analytical solution, model calibration and prediction uncertainty AN - 1420512541; 2013-064182 AB - A vertically-integrated analytical model for dissolved phase transport is described that considers a time-dependent DNAPL source based on the upscaled dissolution kinetics model of Parker and Park with extensions to consider time-dependent source zone biodecay, partial source mass reduction, and remediation-enhanced source dissolution kinetics. The model also considers spatial variability in aqueous plume decay, which is treated as the sum of aqueous biodecay and volatilization due to diffusive transport and barometric pumping through the unsaturated zone. The model is implemented in Excel/VBA coupled with (1) an inverse solution that utilizes prior information on model parameters and their uncertainty to condition the solution, and (2) an error analysis module that computes parameter covariances and total prediction uncertainty due to regression error and parameter uncertainty. A hypothetical case study is presented to evaluate the feasibility of calibrating the model from limited noisy field data. The results indicate that prediction uncertainty increases significantly over time following calibration, primarily due to propagation of parameter uncertainty. However, differences between the predicted performance of source zone partial mass reduction and the known true performance were reasonably small. Furthermore, a clear difference is observed between the predicted performance for the remedial action scenario versus that for a no-action scenario, which is consistent with the true system behavior. The results suggest that the model formulation can be effectively utilized to assess monitored natural attenuation and source remediation options if careful attention is given to model calibration and prediction uncertainty issues.

AN - 69828970; 19031894 AB - Many geochemical reactions that control aqueous metal concentrations are directly affected by solution pH. However, changes in solution pH are strongly buffered by various aqueous phase and solid phase precipitation/dissolution and adsorption/desorption reactions. The ability to predict acid-base behavior of the soil-solution system is thus critical to predict metal transport under variable pH conditions. This studywas undertaken to develop a practical generic geochemical modeling approach to predict aqueous and solid phase concentrations of metals and anions during conditions of acid or base additions. The method of Spalding and Spalding was utilized to model soil buffer capacity and pH-dependent cation exchange capacity by treating aquifer solids as a polyprotic acid. To simulate the dynamic and pH-dependent anion exchange capacity, the aquifer solids were simultaneously treated as a polyprotic base controlled by mineral precipitation/ dissolution reactions. An equilibrium reaction model that describes aqueous complexation, precipitation, sorption and soil buffering with pH-dependent ion exchange was developed using HydroGeoChem v5.0 (HGC5). Comparison of model results with experimental titration data of pH, Al, Ca, Mg, Sr, Mn, Ni, Co, and SO4(2-) for contaminated sediments indicated close agreement suggesting that the model could potentially be used to predictthe acid-base behavior of the sediment-solution system under variable pH conditions.

Resource managers on military installations have the delicate task of balancing the training needs of soldiers effectively with the need to maintain a high quality of ecological conditions. This study considers ways that ecological indicators can provide information on impacts that training has on environmental characteristics that occur at different scales and in different sectors of the environment. The characteristics examined include soil chemistry, soil microbes, and vegetation. A discriminant function analysis was conducted to determine whether ecological indicators could differentiate among different levels of military use. A combination of 10 indicators explained 90% of the variation among plots from five different military use levels. Results indicated that an appropriate suite of ecological indicators for military resource managers includes soil, microbial, and vegetation characteristics. Since many of these indicators are related, managers at this location potentially have freedom to choose indicators that are relatively easy to measure, without sacrificing information.

Issues related to the supply of ethanol, which may turn out to be of even greater concern, are not analyzed here. A model of consumers' decisions to purchase E85 versus gasoline based on prices, availability, and refueling frequency is derived, and preliminary results for 2010, 2017, and 2030 consistent with the president's 2007 biofuels program goals are presented. A limited sensitivity analysis is carried out to indicate key uncertainties in the trade-off between the number of stations and fuels. The analysis indicates that to meet a 2017 goal of 26 billion gallons of E85 sold, on the order of 30% to 80% of all stations may need to offer E85 and that 125 to 200 million flexible-fuel vehicles (FFVs) may need to be on the road, even if oil prices remain high. These conclusions are tentative for three reasons: there is considerable uncertainty about key parameter values, such as the price elasticity of choice between E85 and gasoline; the future prices of E85 and gasoline are uncertain; and the method of analysis used is highly aggregated--it does not consider the potential benefits of regional strategies or the possible existence of market segments predisposed to purchase E85. Nonetheless, the preliminary results indicate that the 2017 biofuels program goals are ambitious and will require a massive effort to produce enough FFVs and ensure widespread availability of E85.

Data were measured continuously up to a fast neutron dose of approximately 1 x 10[super]25 n/m[super]2 (E 0.1 MeV). Data are interpreted in terms of the added thermal resistance and materials compared on this basis. Following this analysis it is shown that for the three materials studied, which have significantly different initial thermal conductivity values, the accumulation of thermal resistance is greater for the materials with lower initial thermal conductivity. Given that vacancies dominate phonon scattering at these irradiation temperatures and dose levels, these data clearly indicate that materials of higher perfection have a slower rate of stable vacancy accumulation during irradiation.

Over the irradiation temperature range studied ([not, vert, similar]850-1475 [deg]C) and neutron dose range (2-10 x 10[super]25 n/m[super]2 (E 0.1 MeV)) the Graftech PCEA and SGL NBG-10 candidate nuclear graphite had similar densification to that of Great Lakes Carbon nuclear graphite H-451. In this temperature and dose range all materials remained in the densification stage. Additionally, the effect of high-temperature irradiation on the dimensional stability of high-quality carbon fiber composites was investigated. A high thermal conductivity three-dimensional carbon fiber composite, FMI-222, and a very high thermal conductivity one-dimensional carbon fiber composite MKC-1PH, were studied. Results indicate that a greater than anticipated dimensional change occurred for these composites. Moreover, the dimensional stability of the 3D composite appears to be a strong function of the sample size chosen, thus raising the question of the appropriate size sample to use to determine irradiation-induced dimensional change for these materials.

The basis of the creep model is discussed and the experimental data required to evaluate the terms in the creep model are reported and discussed. The model, which corrects the true (crystal) creep strain for the effect of creep on the dimensional change component of the creep specimen, is shown to be a good fit to the data. Creep strain data for H-451 graphite irradiated at 900 [deg]C under a tensile stress of 6 MPa are also reported, along with the required experimental data to evaluate the terms in the creep model. The model is shown to inadequately represent the high dose (post volume turn-around) H-451 tensile creep strain data. Reasons for the models limitation are discussed and an approach to a potentially improved graphite irradiation creep model is suggested.

The VHTR can have a prismatic or pebble bed design and is powered by TRISO fuel in the form of a fuel compact (prismatic) or pebble (pebble bed). The US is scheduled to build a demonstration VHTR at the Idaho National Laboratory site by 2020. The first step toward building of this facility is development and qualification of the fuel for the reactor. This paper summarizes the research and development efforts performed at Oak Ridge National Laboratory (ORNL) toward development of a qualified fuel compact for a VHTR.

Using standard size (and shape) specimens, large enough in size to accommodate the inherent local microstructure differences between graphite samples, resulted in non-uniform oxidation profiles and preferential binder oxidation; this was not expected based on the linearity of Arrhenius plots and the (large) values of activation energy. It was found that the transition between the regimes 1 and 2 of graphite oxidation occurs gradually, depending both on the oxidation temperature and rate of oxygen supply. Nevertheless, measuring oxidation rates obtained on standard size samples provides a basis for a meaningful comparison among materials, which may serve as much needed information for predictive models.

Risk is calculated as a quantitative value representing population at risk from exposure at standard exposure levels. Historical meteorological data are used to characterize weather conditions as the frequency of wind speed and direction pairs. The meteorological data drive atmospheric transport and dispersion modeling of the threats, the results of which are used to calculate risk values. Sensor locations are determined via an iterative dynamic programming algorithm whereby threats detected by sensors placed in prior iterations are removed from consideration in subsequent iterations. In addition to the risk-based placement algorithm, the proposed methodology provides a quantification of the marginal utility of each additional sensor. This is the fraction of the total risk accounted for by placement of the sensor.

2011-033202 AB - Contaminants in radioactive wastewaters disposed of into the Y-12 Security Complex S-3 ponds for 32 years have migrated into the surrounding soil and groundwater. This experiment studied the potential role of organo-polyphosphates for uranium and thorium adsorption and immobilization. Phytate is a naturally occurring polyphosphate produced commercially for its utility as a metal chelating and precipitating agent. Polyphosphates can react with contaminants by adsorption, ion exchange, and/or coprecipitation. Forty small (5-10 g) permeable environmental leaching capsules (PELCAPs) were prepared to contain polyacrylamide, alone or in association with soil and polyphosphates. PELCAPs were submerged in contaminated groundwater then repeatedly retrieved and assayed using X-ray fluorescence spectrometry (XRF). Uranium and Th levels were compared to other elements (Sr, Rb, Fe, Mn, and Zr) which remained relatively constant. The small uptake of U and Th by polyacrylamide alone reflected the diffusion of dissolved ions into the gel. Thorium uptake was initially highest by soil only, but the final values of soil and soil + phytates were relatively similar. Uranium uptake values were initially highest in soil + Na phytate, but uptake was quickly dominated by soil + Ca phytate. Future studies will determine the mechanisms of attenuation and degree of leaching of the contaminant-laden PELCAPs. One-half of the PELCAPs will undergo sequential laboratory extractions to determine rates of ion diffusion by deionized water, weak ionic exchange by dissolved salts, and extraction of adsorbed soil oxides by dilute acid. The other half of the PELCAPs will be submerged in uncontaminated in situ groundwater. PELCAPs will be analyzed to determine which materials maintain radionuclide fixation longest relative to the contaminant uptake. As XRF data are insufficient to conclude the specific means of attenuation, the additional analytical methods of laboratory extractions and in situ leaching will assist in determining these mechanisms of radionuclide fixation.

However, the paleoecological meaning of carbon isotopes in pedogenic carbonate can change with the scale at which one considers the data. We describe studies of modern soils, paleosols, and C4/C3 vegetation boundaries in the Chihuahuan Desert of North America and elsewhere which reveal four scales important for paleoecologic interpretations. (1) At the broadest scale, the biome scale (tens to thousands of km), an isotopic record interpreted as C3 forests replacing C4 grasslands may actually represent C3 desertscrub replacing C4 grasslands as the result of aridity. (2) At the landscape scale (hundreds m to km), an isotopic record of paleoecology can be influenced by landforms, which has bearing on the accuracy of scaling up paleoclimatic interpretations to larger regions. (3) At the soil profile scale (m), an isotopic record contained in soils of stable geomorphic surfaces will be more overprinted (and less detailed) than isotopic records in soils of aggrading environments. (4) At the rhizosphere scale (mu m to mm), carbonates formed on roots lack the 14-17ppm enrichment observed at broader scales, revealing different fractionation processes at different scales. A multi-scale approach applied to carbon isotopes in pedogenic carbonate will improve accuracy of paleoecologic interpretations and increase understanding of landscape processes that impact C4/C3 competition.

At the field-scale, such pore-scale processes result in transport parameters being dependent on the scale of measurement. Because of the difficulty in examining flow and transport in the field, few studies have correlated pore structure with contaminant transport, which is the objective of this study. Intact, layered, heterogeneous sediment cores were collected such that flow was imposed parallel to or perpendicular to bedding. Nonreactive tracers, uranium(VI), cobalt-EDTA (ethylenediaminetetraacetate), and Brilliant Blue FCF dye were applied under partially-saturated conditions. Subsequently, the cores were dissembled and sectioned to determine the distribution of particle size, dye, and water content with respect to layering. A relationship was found between particle size, water content and flowpaths within wet, fine-grained layers when flow was imposed parallel to beds. This indicated extensive flow bypassing of dry, coarser-grained sediments and explained observed high dispersivity values, multiple U(VI) peaks, and a low modeled effective water content. Cores in which flow crosses beds are currently in preparation. It is predicted that flow will interact to a greater extent with dry, coarse-grained beds than when flow was exclusively parallel to beds, but that the extent of interaction will be dependent upon water content and characteristics of layering. The final results of this study will determine linkages between sedimentary pore structure, water content, and contaminant transport in anisotropic unsaturated media.

Cephapirin sodium salt (CHP) is a first generation cephalosporin antibiotic used widely in the dairy cattle industry. Raman spectroscopy was used to investigate the mechanisms of CHP adsorption onto quartz (SiO (sub 2) ) and feldspars at different solution pH values. Depending on the charge and surface properties of the mineral, different reaction mechanisms including electrostatic attraction, monodentate and bidentate complexation were found to be responsible for CHP sorption. The zwitterion (CHP degrees ) adsorbs to a quartz (super (+)) surface by electrostatic attraction of the carboxylate anion group (-COO (super -) ) at a low pH, but adsorbs to a quartz (super (-)) surface through electrostatic attraction of the pyridinium cation and possibly COO (super -) bridge complexes at higher pH conditions. CHP (super -) bonds to a quartz (super (-)) surface by bidentate complexation between one oxygen of -COO (super -) and oxygen from the carbonyl (C=O) of the acetoxymethyl group. On an orthoclase feldspar (KAlSi (sub 3) O (sub 8) ) surface of mixed charge, CHP degrees forms monodentate complexes between C=O as well as possible -COO (super -) bridges and/or electrostatic attachments to localized edge (hydr)oxy-Al surfaces. CHP (super -) adsorbs to orthoclase (super (-)) through monodentate C=O complexation. Additional preliminary data suggest that related mechanisms are responsible for CHP adsorption to albite (NaAlSi (sub 3) O (sub 8) ) and other Na-Ca plagioclase feldspars. Mechanisms observed in the current study may operate for the sorption of other cephalosporin antibiotics with similar functional group chemistry. This research demonstrates that Raman spectroscopic techniques can be effective for evaluating sorption processes and mechanisms of a hydrophilic antibiotic at relatively low sorbed concentrations ( approximately 100 mu mol/kg range).

Synthetic ClO (sub 4) (super -) is enriched locally in areas affected by military and industrial activities, whereas natural ClO (sub 4) (super -) is widely distributed in arid environments, possibly as a result of atmospheric deposition and evapotranspirative concentration. In addition, ClO (sub 4) (super -) appears to be present in some areas as a result of agricultural application of natural nitrate (NO (sub 3) (super -) ) fertilizer containing ClO (sub 4) (super -) from the Atacama Desert in Chile. Because the ClO (sub 4) (super -) /NO (sub 3) (super -) ratio of Atacama NO (sub 3) (super -) deposits and historical fertilizer products is higher than the ClO (sub 4) (super -) /NO (sub 3) (super -) ratio of recommended drinking-water limits, ClO (sub 4) (super -) can exceed drinking-water limits even where Atacama NO (sub 3) (super -) was only a small fraction of the total fertilizer N applied. Atacama ClO (sub 4) (super -) is presumed to have accumulated with NO (sub 3) (super -) largely from atmospheric deposition and is recognized isotopically by low delta (super 37) Cl and high Delta (super 17) O values. ClO (sub 4) (super -) with these isotopic characteristics is a sensitive indicator of Atacama NO (sub 3) (super -) fertilizer use and has been identified in groundwater from several areas of the USA. At one such site in New York beneath agricultural land, concentrations of ClO (sub 4) (super -) are relatively low near the water table and higher in deeper older groundwaters (20-30 yrs), possibly because application rates of Atacama NO (sub 3) (super -) fertilizer, and(or) ClO (sub 4) (super -) concentrations in the imported fertilizer products, decreased in recent years. Similarly, groundwater ClO (sub 4) (super -) in some former agricultural sites in southern California is plausibly related to past Atacama NO (sub 3) (super -) fertilizer use. After entering groundwater, ClO (sub 4) (super -) and NO (sub 3) (super -) both are persistent in oxic conditions and are subject to microbial reduction under suboxic conditions, although ClO (sub 4) (super -) degradation commonly is inhibited in the presence of NO (sub 3) (super -) . During biodegradation, ClO (sub 4) (super -) and NO (sub 3) (super -) exhibit coupled isotopic fractionation with relatively constant ratios of epsilon O/epsilon Cl ( nearly equal 2.5 + or - 0.2) and epsilon O/epsilon N ( nearly equal 0.8 + or - 0.2), respectively.

This increased CO (sub 2) is believed to be responsible for a significant rise in global temperature over the past several decades. Global-scale climate modeling suggests that the temperature increase will continue, at least over the next few hundred years, leading to glacial melting and rising sea levels. Increased atmospheric CO (sub 2) also leads to ocean acidification, which will have drastic consequences for marine ecosystems. In an attempt to solve these problems, many have proposed the large-scale sequestration of CO (sub 2) from our atmosphere. This introductory article presents a summary of some of the evidence linking increasing atmospheric CO (sub 2) concentration to global warming and ocean acidification and our efforts to stem this rise though CO (sub 2) sequestration.

If CCS is implemented on the scale needed to make noticeable reductions in atmospheric CO (sub 2) , a billion metric tons or more must be sequestered annually--a 250 fold increase over the amount sequestered today. Securing such a large volume will require a solid scientific foundation defining the coupled hydrologic-geochemical-geomechanical processes that govern the long-term fate of CO (sub 2) in the subsurface. Also needed are methods to characterize and select sequestration sites, subsurface engineering to optimize performance and cost, approaches to ensure safe operation, monitoring technology, remediation methods, regulatory overview, and an institutional approach for managing long-term liability.

Rhodococcus erythropolis, IGTS8 was used as the biocatalyst. Optimal conditions for bacterial growth and DBT desulfurization were investigated. Optimization of fermentation conditions was necessary to obtain high cell densities including controlling accumulation of acetate. Under optimal operating conditions, the maximum optical density at 600 nm (OD600) was measured to be 26.6 at 118 h of cultivation. When biodesulfurization of DBT in model oil with a high cell density culture of IGTS8 was investigated, accumulation of sulfate was found to limit the extent of desulfurization. A sulfate removal step was added to obtain a single-stage integrated biodesulfurization process. Sulfate removal was achieved via an aqueous bleed stream and use of a separation unit to recycle the organic phase. A proof of principle of a complete system capable of biocatalyst growth, induction, desulfurization and by-product separation was demonstrated. This system enables simplification of the biodesulfurization process and has potential to lower the operating cost of the bioprocess.

As part of the recent US Department of Energy's Advanced Gas Reactor Fuel Development and Qualification program, Oak Ridge National Laboratory has utilized advancements in computer automation, digital imaging, and image analysis to modernize US optical microscopy techniques for coated particle nuclear fuel. Automated optical microscopy has enabled detailed and objective analysis of individual particles (hundreds of measurements per particle) and of large sample sizes that far exceed the capabilities of conventional manual microscopy methods (analysis of 1500-5000 particles is common). Demonstrative examples of the capabilities of this automated optical microscopy are given for: (a) shadow imaging of kernels, coated fuel particles, and graphite matrix overcoated particles and (b) cross-sectional analysis of coated fuel particles to determine layer thicknesses.

These results, along with historical application records, are used to estimate vertical-migration rates and perform a mass balance. The presence of (super 60) Co results solely from the sludge-application process. Soil, vegetation, and surface-water samples were collected. Eleven soil cores were sectioned into 3-cm increments and analyzed by gamma-ray spectrometry. No (super 60) Co was detected in the vegetation or water samples. The downward migration rate of (super 60) Co in the upper 15 cm of soil ranged from 0.50 to 0.73 cm/yr.

The scanning microbeam setup we have developed at the XOR-UNI beamline at the Advanced Photon Source (APS) is versatile in that it provides 1D, 2D or 3D scans (including depth resolution), and can alternate between polychromatic- and monochromatic-beam modes. Focusing in both modes uses elliptical Kirkpatrick-Baez (K-B) reflecting mirrors. Beam diameters of ~500 nm FWHM are now routine, and 90 nm focus has been demonstrated. In white-beam mode, a CCD detector records a complete Laue diffraction pattern, which is analyzed with an automated indexing program. These X-ray diffraction patterns provide real-space maps of the local lattice structure, crystal orientation, grain morphology, and strain tensor. Spatially-resolved X-ray microdiffraction studies are now providing previously unavailable measurements of local microstructures. These measurements, in turn, yield new insights in several classic fields of materials science. This paper will illustrate the application of polychromatic scanning X-ray microscopy with examples from 1D, 2D and 3D materials systems. In 1D systems, we have mapped the structure and orientation of an individual ZnO nanorod along with the associated Ge catalyst particle used to control the nanocrystal growth. In 2D systems, X-ray microdiffraction studies have revealed the mechanisms for local crystallographic tilting in epitaxial oxide films grown on textured Ni substrates for superconducting applications. In 3D systems, X-ray microscopy investigations have included in-situ studies of microstructural evolution during thermal grain growth in polycrystalline aluminum. In general, these spatially-resolved measurements provide important new insights and are valuable as input for theoretical and computer modeling studies of a wide range of material processes.

The U containing precipitates fluoresce a bright green under ultraviolet (UV) short-wave light which identify U-rich coatings on the gravel. Scanning electron microscopy (SEM) microprobe analysis show U concentration ranges from 1.6-19.8% (average of 7%) within the coatings with higher concentrations at the interface of the dolomite fragments. X-ray absorption near edge structure spectroscopy (XANES) indicate that the U is hexavalent and extended X-ray absorption fine structure spectroscopy (EXAFS) shows that the uranyl is coordinated by carbonate. The exact nature of the uranyl carbonates are difficult to determine, but some are best described by a split K+-like shell similar to grimselite [K4Na(UO2)(CO3)3.H2O] and other regions are better described by a single Ca2+-like shell similar to liebigite [Ca2(UO2)(CO3)3.11(H2O)] or andersonite [Na2CaUO2(CO3)3 . 6H2O]. The U precipitates are found in the form of white to light yellow cracked-formations as coatings on the dolomite gravel and as detached individual precipitates, and are associated with amorphous basalumnite [Al4(SO4)(OH)10.4H2O].

In this study the intent of habitat valuation was to inform the decision-making process for remediation of chemical contaminants on specific lands or surface water bodies. Methods were developed to summarize dimensions of habitat value for six representative aquatic and terrestrial contaminated sites at the East Tennessee Technology Park (ETTP) on the US Department of Energy Oak Ridge Reservation in Oak Ridge, TN, USA. Several general valuation metrics were developed for three broad categories: site use by groups of organisms, site rarity, and use value added from spatial context. Examples of use value metrics are taxa richness, a direct measure of number of species that inhabit an area, complexity of habitat structure, an indirect measure of potential number of species that may use the area, and land use designation, a measure of the length of time that the area will be available for use. Measures of rarity included presence of rare species or communities. Examples of metrics for habitat use value added from spatial context included similarity or complementarity of neighboring habitat patches and presence of habitat corridors. More specific metrics were developed for groups of organisms in contaminated streams, ponds, and terrestrial ecosystems. For each of these metrics, cutoff values for high, medium, and low habitat value were suggested, based on available information on distributions of organisms and landscape features, as well as habitat use information. A companion paper describes the implementation of these habitat valuation metrics and scoring criteria in the remedial investigation for ETTP.

The scheme is based on an a posteriori error estimate for the discontinuous Galerkin finite-element methods. A stability factor is involved in the error estimate and it is used to adapt the time step and control the global temporal error for the backward Euler method. The stability factor can be estimated by solving a dual problem. The stability factor is not sensitive to the accuracy of the dual solution and the overhead computational cost can be minimized by solving the dual problem using large time steps. Numerical experiments are conducted to show the application and the performance of the automatic time stepping scheme. Implementation of the scheme can lead to improvements in accuracy and efficiency of groundwater flow models.

The focus of the assessment was a testing program at the Cibola Range, which involved an Apache Longbow helicopter firing Hellfire missiles at moving targets, that is, M60-A1 tanks. The problem formulation for the assessment included conceptual models for three component activities of the test, helicopter overflight, missile firing, and tracked vehicle movement, and two ecological endpoint entities, woody desert wash communities and desert mule deer (Odocoileus hemionus crooki) populations. An activity-specific risk assessment framework was available to provide guidance for assessing risks associated with aircraft overflights. Key environmental features of the assessment area include barren desert pavement and tree-lined desert washes. The primary stressors associated with helicopter overflights were sound and the view of the aircraft. The primary stressor associated with Hellfire missile firing was sound. The principal stressor associated with tracked vehicle movement was soil disturbance, and a resulting, secondary stressor was hydrological change. Water loss to desert washes and wash vegetation was expected to result from increased ponding, infiltration, and/or evaporation associated with disturbances to desert pavement. A plan for estimating integrated risks from the three military activities was included in the problem formulation.

The focus was a testing program at Cibola Range that involved an Apache Longbow helicopter firing Hellfire missiles at moving targets, that is, M60-A1 tanks. This article describes the ecological risk assessment, using the MERAF, for the tracked vehicle movement component of the testing program. The principal stressor associated with tracked vehicle movement was soil disturbance, and a resulting, secondary stressor was hydrological change. Water loss to desert wash vegetation was hypothesized to result from increased infiltration and/or evaporation associated with vehicle disturbances to surrounding desert pavement, potentially affecting mule deer as well as vegetation. The simulated exposure of wash vegetation to water loss was quantified using estimates of disturbed land area from a digital orthogonal quarter quadrangle aerial photo and field observations, a 30-m digital elevation model, the flow accumulation feature of ESRI ArcInfo GIS, and a two-step runoff process dependent on soil characteristics and the extent of disturbance. In all simulated scenarios, the absolute amount of water lost increased with distance from the disturbance downslope in the washes; however, the percentage of water lost was greatest in land areas immediately downslope of a disturbance. Potential effects on growth and survival of desert wash trees were quantified by comparing water availability from the hydrologic model to water volume thresholds required for wash trees to survive and persist, derived from a local study. For both the incremental risk of the test program and for the combination of test and pretest disturbances, this demonstration of MERAF found no significant risk to either wash vegetation growth and survival or mule deer abundance and reproduction.

The focus was a testing program at Cibola Range, which involved an Apache Longbow helicopter firing Hellfire missiles at moving targets, that is, M60-A1 tanks. This article describes the ecological risk assessment for the missile launch and detonation. The primary stressor associated with this activity was sound. Other minor stressors included the detonation impact, shrapnel, and fire. Exposure to desert mule deer (Odocoileus hemionus crooki) was quantified using the Army sound contour program BNOISE2, as well as distances from the explosion to deer. Few effects data were available from related studies. Exposure-response models for the characterization of effects consisted of human 'disturbance' and hearing damage thresholds in units of C-weighted decibels (sound exposure level) and a distance-based No-Observed-Adverse-Effects Level for moose and cannonfire. The risk characterization used a weight-of-evidence approach and concluded that risk to mule deer behavior from the missile firing was likely for a negligible number of deer, but that no risk to mule deer abundance and reproduction is expected.

Major constraints for grassland restoration are high soil fertility and limited dispersal ability of plant species to target sites. Usually, studies focus on soil fertility or on methods to introduce plant seeds. However, the question is whether soil fertility reduction is always necessary for getting plant species established on target sites. In a three-year field experiment with ex-arable soil with intensive farming history, we tested single and combined effects of soil fertility reduction and sowing mid-successional plant species on plant community development and soil biological properties. A controlled microcosm study was performed to test short-term effects of soil fertility reduction measures on biomass production of mid-successional species. Soil fertility was manipulated by adding carbon (wood or straw) to incorporate plant-available nutrients into organic matter, or by removing nutrients through top soil removal (TSR). The sown species established successfully and their establishment was independent of carbon amendments. TSR reduced plant biomass, and effectively suppressed arable weeds, however, created a desert-like environment, inhibiting the effectiveness of sowing mid-successional plant species. Adding straw or wood resulted in short-term reduction of plant biomass, suggesting a temporal decrease in plant-available nutrients by microbial immobilisation. Straw and wood addition had little effects on soil biological properties, whereas TSR profoundly reduced numbers of bacteria, fungal biomass and nematode abundance. In conclusion, in ex-arable soils, on a short-term sowing is more effective for grassland restoration than strategies aiming at soil fertility reduction.

infrared spectroscopic investigation AN - 50608206; 2008-114714 AB - The structural variations of synthetic zircon (ZrSiO (sub 4) ) single crystals irradiated at room temperature by 280 keV Pb (super +) ions (with fluences up to 1X10 (super 15) ions/cm (super 2) ) were investigated using infrared (IR) spectroscopy. Like metamict zircon whose crystal structure is damaged and amorphized by naturally occurring alpha -decay events, the Pb (super +) -irradiated zircon crystals show a dramatic decrease in reflectivity. However, no significant decrease in wavenumbers of the stretching vibrations of SiO (sub 4) tetrahedra in zircon was detected. The Pb (super +) -implanted zircon exhibits new IR bands, indicating irradiation-induced new vibrations or domains, clusters or phases in addition to SiO (sub 2) and ZrO (sub 2) . IR features consistent with those of Pb silicates (with a divalent state, i.e., Pb (super 2+) ) are also found in the irradiated sample. This finding implies that some of the radiogenic Pb in natural zircon might not actually reside in the zircon lattice or in ZrSiO (sub 4) phases, but form new local domains or clusters. Infrared bands of OH-stretching vibrations were also detected in the irradiated synthetic zircon, which was originally free from OH features prior to the irradiation. These results indicate that H can easily diffuse into the irradiated layer or into irradiated-induced phases to form OH or and hydrous species after the irradiated material is damaged. The type and content of hydrous species vary with irradiation fluences.

Electricity production using its natural electron acceptor, iron, as the electron mediating agent at pH values ,4.0 was demonstrated. Accumulation of Fe(III) at the electrode, however, restricted current output. The combination of nitrilotriacetic acid and Phenosafranin as electron mediators increased the power output to 12.7mW/m super(2) in a two-chamber air-sparged fuel cell. Direct electron transfer from the microorganisms to the anode was also investigated but was not detected under the conditions studied.

In the aqueous concentration range investigated (11-112 mu mol/L cephapirin), adsorption to nearly pure quartz filter sands (0.50-3.35 mm diameter) is low. Isotherms are S-shaped and most display a region of minimum adsorption, where decreased adsorption occurs with increasing solution concentration, followed by increased adsorption at higher concentrations. Cephapirin adsorption to quartz-rich, feldspar-bearing dune sands (0.06-0.35 mm diameter), and the smallest quartz filter sand investigated (0.43-0.50 mm), can be described by linear sorption isotherms over the range of concentrations investigated. Distribution coefficients (K sub(d)) range from 0.94 to 3.45 L/kg. No systematic relationship exists between grain size and amount of adsorption for any of the sands investigated. Cephapirin adsorption is positively correlated to the feldspar ratio (K-feldspar/(albite + Ca-plagioclase). Feldspar-ratio normalization of distribution coefficients was more effective than organic carbon normalization at reducing variability of K sub(d) values in the dune sands investigated.Original Abstract: Des experiences par lots ont ete realisees pour etudier l'adsorption de la cefapirine (un antibiotique tres utilise en veterinaire) sur differentes tailles de sables a faible teneur en carbone organique (0.08-0.36% du poids total). Dans les concentrations aqueuses investies (11 a 112 mu mol/L de cefapirine), l'adsorption sur des sables de quartz pratiquement purs (diametre de 0.50-3.35 mm) est faible. Les isothermes ont une forme en S et representent surtout une region d'adsorption minimum, ou la decroissance de l'adsorption apparait avec une augmentation de la concentration de la solution, suivie par une augmentation de l'adsorption a des concentrations plus importantes. L'adsorption de la cefapirine sur du sable (0.06-0.35 mm) de dune riche en quartz et contenant du feldspath et un filtre a sable quartzeux plus petit (0.43-0.50 mm), peut etre decrit par des isothermes de sorption lineaires sur l'echelle de concentrations etudiees. Les coefficients de distribution (K sub(d)) se situent entre 0.94 et 3.45 L/kg. Pour tous les sables etudies aucune relation systematique n'existe entre la taille des grains et l'importance de l'adsorption. L'adsorption de la cefapirine est correlee positivement avec le rapport de feldspath (K-feldspath/(albite + Ca-plagioclase). La normalisation des coefficients de distribution par rapport au rapport de Feldspath est plus efficace que la normalisation par rapport au carbone organique a des variabilites de K sub(d) reduites dans les sables de dune etudies. Experimentos en batch fueron realizados para investigar la adsorpcion de cefapirina (un antibiotico veterinario usado ampliamente) en arenas de varios tamanos con bajo contenido de carbon organico total (0.08-0.36%pt.). En el rango de concentracion acuosa investigado (11 to 112 mu mol/L, de cefapirina), la adsorpcion es baja en filtros de arenas con cuarzo casi puro (0.50-3.35 mm-diametro). Las isotermas tienen forma-S y la mayoria muestran una region de adsorpcion minima, donde ocurre adsorpcion decreciente con concentracion de solucion creciente, seguida por un incremento de adsorpcion a concentraciones mayores. La adsorpcion de cefapirina en dunas de arenas ricas en cuarzo y conteniendo feldespato (0.06-0.35 mm-diametro), y en el filtro de arena mas pequeno investigado (0.43-0.50 mm), puede ser descrita por isotermas de sorpcion lineales en todo el rango de concentraciones investigado. Los coeficientes de distribucion (K sub(d)) van de 0.94 a 3.45 L/kg. No existe relacion sistematica entre la granulometria y la cantidad de adsorpcion en ninguna de las arenas investigadas. La adsorpcion de cefapirina esta positivamente correlacionada con la razon de feldespato (K-feldespato/(albita + Ca-plagioclasa). La normalizacion de coeficientes de distribucion de la razon de feldespato fue mas efectiva que la normalizacion de carbon organico en la reduccion de variabilidad de valores de K sub(d) en las dunas de arena investigadas.

Inhalation of nanoparticles is of great concern, because nanoparticles can be easily aerosolized. Imaging techniques that can visualize local populations of nanoparticles at nanometre resolution within the structures of cells are therefore important super(3). Here we show that cells obtained from mice exposed to single-walled carbon nanohorns can be probed using a scanning probe microscopy technique called scanning near field ultrasonic holography. The nanohorns were observed inside the cells, and this was further confirmed using micro Raman spectroscopy. Scanning near field ultrasonic holography is a useful technique for probing the interactions of engineered nanomaterials in biological systems, which will greatly benefit areas in drug delivery and nanotoxicology.

The new steels were patterned after the commercial steels, with the objective that the new steels have yield stress and ultimate tensile strength and impact toughness in a Charpy test comparable to or better than the steels they replaced. That objective was achieved in reduced-activation steels developed in Japan, Europe, and the United States. Although tensile and impact toughness of the reduced-activation steels exceed those of the commercial steels they were patterned after, their creep-rupture properties are inferior to some commercial steels they replaced. They are even more inferior to commercial steels developed since the 1980s. In this paper, compositional differences between reduced-activation steels and new commercial steels are examined, and compositions are proposed for development of new-and-improved reduced-activation steels.

Modeling efforts that attempt to treat all counties as equivalent units, while assuming a homogeneous modeling structure for all the units, may miss important information regarding the statistical and causal relationships between economic activity and transportation infrastructure. This study examines the interrelationships between infrastructure and activity using two Washington State highway infrastructure datasets in combination with county-level employment, wages, and establishment numbers for several industrial sectors for a subset of counties from 1990 to 2004. Estimates using vector autoregressions, error correction models, and directed acyclic graphs are made. The results show that the relationships between infrastructure investment and economic activity are often weak and are not uniform in effect. Adapted from the source document.

Geographic data on the distribution of endangered and threatened species can be used to improve ongoing efforts for species conservation in the United States. At present no spatial database exists which maps out the location of endangered species for the US. However, spatial descriptions do exist for the habitat associated with all endangered species, but in a form not readily suitable to use in a geographic information system (GIS). In our study, the principal challenge was extracting spatial data describing these critical habitats for 472 species from over 1000 pages of the Federal Register. In addition, an appropriate database schema was designed to accommodate the different tiers of information associated with the species along with the confidence of designation; the interpreted location data was geo-referenced to the county enumeration unit producing a spatial database of endangered species for the whole of US. The significance of these critical habitat designations, database scheme and methodologies will be discussed. Adapted from the source document.

Comparisons between high- and low-temperature diffusion studies suggest that several factors play important roles under lower-temperature conditions that are not significant at higher temperatures. Water concentrations in rhyolitic glasses hydrated at low temperatures are significantly greater than in those hydrated at high temperatures and low pressures. Surface concentrations, which equilibrate quickly with the surrounding environment at high temperature, change far more slowly as temperature decreases, and may not equilibrate at room temperature for hundreds or thousands of years. Temperature extrapolations of high- and low-temperature diffusion data are not consistent, suggesting that a change in mechanism occurs. These differences may be due to the inability of "self-stress", caused by the in-diffusing species, to relax at lower temperature. Preliminary calculations suggest that the level of stress caused by glass-water interaction may be greater than the tensile strength of the glass. On a microstuctural scale, extrapolations of high-temperature Fourier transform infrared spectroscopy (FTIR) data to lower temperatures suggests that there should be little or no hydroxyl present in glasses hydrated at low temperature. Comparisons of low-temperature hydration results among SiO (sub 2) , obsidian, and albite compositions show distinct differences, and features are present in the spectra that do not occur at high temperature. Analysis of H (sub 2) O and D (sub 2) O diffusion also suggest that mechanistic differences occur between low- and high-temperature diffusive processes.

Operational characteristics of pressure-driven separations are in part controlled by the membrane pore size, charge of particulates, transmembrane pressure and the requirement for sufficient water flux to overcome fouling. With long term use filters decline in permeance due to filter-cake plugging of pores, fouling, or filter deterioration. Though metallic filter tube development at ORNL has focused almost exclusively on gas separations, a small study examined the applicability of these membranes for tangential filtering of aqueous suspensions of bacterial-sized particles. A mixture of fluorescent polystyrene microspheres ranging in size from 0.5 to 6 mu m in diameter simulated microorganisms in filtration studies. Compared to a commercial filter, the ORNL 0.6 mu m filter averaged approximately 10-fold greater filtration efficiency of the small particles, several-fold greater permeance after considerable use and it returned to approximately 85% of the initial flow upon backflushing versus 30% for the commercial filter. After filtering several liters of the particle-containing suspension, the ORNL composite filter still exhibited greater than 50% of its initial permeance while the commercial filter had decreased to less than 20%. When considering a greater filtration efficiency, greater permeance per unit mass, greater percentage of rejuvenation upon backflushing (up to 3-fold), and likely greater performance with extended use, the ORNL 0.6 mu m filters can potentially outperform the commercial filter by factors of 100-1000 fold.

Specimens were irradiated at reactor coolant temperature (80 DGC) to doses ranging from 7.2 X 10-5 to 0.28 dpa in the High Flux Isotope Reactor. Tensile tests were carried out between -50 and 100 DGC at strain rates of 1 X 10-5-1 X 10-2 s-1. Thermal activation analysis based on tensile data was performed to understand the low-temperature deformation mechanism. Irradiation softening and reduced dependence on test temperature and strain rate of the yield stress was observed in the annealed Mo after low-dose neutron irradiation (<0.003 dpa). Higher dose neutron irradiation caused athermal hardening only. The stress-relieved Mo showed a weaker dependence on test temperature and strain rate of the yield stress than the annealed Mo, and the dependence of the yield stress of the stress-relieved Mo was nearly unchanged after irradiation. Comparison of the experimental values of activation parameters with the theoretical predictions of dislocation models indicates that the Fleischer model of interactions of dislocations with tetragonal strains gave a better description of the activation process than the double-kink model, which implies a scavenging effect. The reduced test temperature and strain rate dependence following irradiation may be explained by the decreased effective stress due to trapping of interstitial solute species by neutron-produced defects.

This irradiation hardening causes embrittlement observed in a Charpy impact test as an increase in the ductile-brittle transition temperature. Little or no change in strength is observed in steels irradiated above 425-450 DGC. Therefore, the general conclusion has been that no embrittlement occurs above these temperatures. In a recent study, significant embrittlement was observed in F82H steel irradiated at 500 DGC to 5 and 20 dpa without any change in strength. Earlier studies on several conventional steels also showed embrittlement effects above the irradiation-hardening temperature regime. Indications are that this embrittlement is caused by irradiation-accelerated or irradiation-induced precipitation. Observations of embrittlement in the absence of irradiation hardening that were previously reported in the literature have been examined and analyzed with computational thermodynamics calculations to illuminate and understand the effect.

Results from X-ray absorption near-edge structure (XANES) spectroscopy revealed that gamma -sterilized sediments were actually better sorbents of U(VI), despite the absence of any measurable biological activity. These results indicate that gamma -irradiation induced significant physico-chemical changes in the sediment which is contrary to numerous other studies identifying gamma -sterilization as an effective and minimally invasive technique. To identify the extent and method of alteration of the soil as a result of gamma -sterilization, untreated soil samples, physically separated size fractions, and chemically extracted fractions of the soil were analyzed pre- and post-sterilization. The effects of sterilization on mineralogy, pH, natural organic matter (NOM), cation exchange capacity (CEC), and iron oxidation state were determined. Results indicated that major mineralogy of the clay and whole sediment samples was unchanged. Sediment pH decreased only slightly with gamma -irradiation; however, irradiation produced a significant decrease in CEC of the untreated sediments and affected both the organic and inorganic fractions. Mossbauer spectra of non-sterile and gamma -sterilized sediments measured more reduced iron present in gamma -sterilized sediments compared to non-sterile samples. Our results suggest that sterilization by gamma -irradiation induced iron reduction that may have increased the sorption and/or reduction of U(VI) onto these sediments. However, Mossbauer and batch sorption data are somewhat contradictory, the former indicates that the iron oxide or iron hydroxide minerals are more significantly reduced while the later indicates that reduced clay minerals account for greater sorption of U(VI).

Organic (O) horizon carbon (C) stocks were measured at several occasions before, during and after the experiment and mineral soil C stocks before and after the experiment. In the O horizon, higher C stocks were observed in the dry treatment compared to the ambient and wet, attributable to a combination of enhanced litter inputs and reduced decomposition. No precipitation treatment effects on mineral soil C stocks were found to a depth of 60cm. Conversely, long-term reductions in surface mineral soil C stocks were surprisingly high for all treatments (3.5-2.7% C in the 0-15cm layer and from 0.6 to 0.5% in the 15-30cm layer) over the duration of the experiment. A clear explanation for this temporal trend in C storage was not readily apparent.

Recently, Hauptman & Langs (2003; Acta Cryst. A59, 250-254) have shown that neutron diffraction data can be used to solve macromolecular structures by direct methods and that solution is aided by the presence of negatively scattering H atoms in the structure. Selective-labeling protocols allow the design and production of H/D-labeled macromolecular structures in which the ratio of H to D atoms can be precisely controlled. Methyl selective-labeling protocols were applied to introduce (1H-d methyl)-leucine and (1H-g methyl)-valine into deuterated rubredoxin from Pyrococcus furiosus (PfRd). Here, the production, crystallization and preliminary neutron analysis of a selectively CH3-protonated deuterated PfRd sample, which provided a high-quality neutron data set that extended to 1.75Aa resolution using the new LADI-III instrument at the Institut Laue-Langevin, are reported. Preliminary analysis of neutron density maps allows unambiguous assignment of the positions of H atoms at the methyl groups of the valine and leucine residues in the otherwise deuterated rubredoxin structure.

Bioreduction was achieved by conditioning groundwater above ground and then stimulating growth of denitrifying, Fe(III)-reducing, and sulfate-reducing bacteria in situ through weekly injection of ethanol into the subsurface. After nearly 2 years of intermittent injection of ethanol, aqueous U levels fell below the U.S. Environmental Protection Agency maximum contaminant level for drinking water and groundwater (<30 kg/liter or 0.126 kM). Sediment microbial communities from the treatment zone were compared with those from a control well without biostimulation. Most-probable-number estimations indicated that microorganisms implicated in bioremediation accumulated in the sediments of the treatment zone but were either absent or in very low numbers in an untreated control area. Organisms belonging to genera known to include U(VI) reducers were detected, including Desulfovibrio, Geobacter, Anaeromyxobacter, Desulfosporosinus, and Acidovorax spp. The predominant sulfate-reducing bacterial species were Desulfovibrio spp., while the iron reducers were represented by Ferribacterium spp. and Geothrix spp. Diversity-based clustering revealed differences between treated and untreated zones and also within samples of the treated area. Spatial differences in community structure within the treatment zone were likely related to the hydraulic pathway and to electron donor metabolism during biostimulation.

Miniature tensile specimens of three pure tantalum metals, ISIS Ta, Aesar Ta1, Aesar Ta2, and one tantalum alloy, Ta-1W, were irradiated by neutrons in the high flux isotope reactor (HFIR) at ORNL to doses ranging from 0.00004 to 0.14 displacements per atom (dpa) in the temperature range 60-100 DGC. Also, two tantalum-tungsten alloys, Ta-1W and Ta-10W, were irradiated by protons and spallation neutrons in the LANSCE facility at LANL to doses ranging from 0.7 to 7.5 dpa and from 0.7 to 25.2 dpa, respectively, in the temperature range 50-160 DGC. Tensile tests were performed at room temperature and at 250 DGC at nominal strain rates of about 10-3 s-1. All neutron-irradiated materials underwent progressive irradiation hardening and loss of ductility with increasing dose. The ISIS Ta experienced embrittlement at 0.14 dpa, while the other metals retained significant necking ductility. Such a premature embrittlement in ISIS Ta is believed to be due to high initial oxygen concentrations picked up during a pre-irradiation anneal. The Ta-1W and Ta-10W specimens irradiated in spallation condition experienced prompt necking at yield since irradiation doses for those specimens were high (0.7 dpa). At the highest dose, 25.2 dpa, the Ta-10W alloy specimen broke with little necking strain. Among the test materials, the Ta-1W alloy displayed the best combination of strength and ductility. The plastic instability stress and true fracture stress were nearly independent of dose. Increasing test temperature decreased strength and delayed the onset of necking at yield.

At the nominal operating power (1.4 MW), it will have thermal neutron fluxes approximately an order of magnitude greater than any existing pulsed spallation source. It thus brings a serious challenge to the lifetime of the moderator poison sheets. The SNS moderators are integrated with the inner reflector plug (IRP) at a cost of $2 million a piece. A replacement of the inner reflector plug presents a significant drawback to the facility due to the activation and the operation cost. Although there are a lot of factors limiting the lifetime of the inner reflector plug, like radiation damage to the structural material and helium production of beryllium, the bottle-neck is the lifetime of the moderator poison sheets. Increasing the thickness of the poison sheet extends the lifetime but would sacrifice the neutronic performance of the moderators. A compromise is accepted at the current SNS target system which uses thick Gd poison sheets at a projected lifetime of 6 MW-years of operation. The calculations in this paper reveal that Cd may be a better poison material from the perspective of lifetime and neutronic performance. In replacing Gd, the inner reflector plug could reach a lifetime of 8 MW-years with 5% higher peak neutron fluxes at almost no loss of energy resolution.

Previous work has shown an order of magnitude decrease in damage for a gas layer developed in a stagnant mercury target for an in-beam experiment. This work is aimed at extending these results to the more complex conditions introduced by a flowing mercury target system. A water-loop has been fabricated to provide initial insights on potential gas injection methods into a flowing liquid. An existing full-scale flow loop designed to simulate the Spallation Neutron Source target system will be used to extend these studies to mercury. A parallel analytical effort is being conducted using computational fluid dynamics (CFD) modeling to provide direction to the experimental effort. Some preliminary simulations of gas injection through a single hole have been completed and show behavior of the models that is qualitatively meaningful.

In support of the Strategic Environmental Research and Development Program project, the particulate matter (PM) and gaseous emissions from two T56 engines on a parked C-130 aircraft were characterized at the Kentucky Air National Guard base in Louisville, KY. Conventional and research-grade instrumentation and methodology were used in the field campaign during the first week of October 2005. Particulate emissions were sampled at the engine exit plane and at 15 m downstream. In addition, remote sensing of the gaseous species was performed via spectroscopic techniques at 5 and 15 m downstream of the engine exit. It was found that PM mass and number concentrations measured at 15-m downstream locations, after dilution-correction generally agreed well with those measured at the engine exhaust plane; however, higher variations were observed in the far-field after natural dilution of the downstream measurements was accounted for. Using carbon dioxide-normalized data we demonstrated that gas species measurements by extractive and remote sensing techniques agreed reasonably well.

Tests were performed using an ultrasonic vibratory horn with specimens attached at the tip. All of the solutes examined, which included 5 wt% In, 10 wt% In, 4.4 wt% Cd, 2 wt% Ga, and a mixture that included 1 wt% each of Pb, Sn, and Zn, were found to increase cavitation-erosion as measured by increased weight loss and/or surface profile development compared to exposures for the same conditions in pure mercury. Qualitatively, each solute appeared to increase the tenacity of the post-test wetting of the Hg solutions and render the Hg mixture susceptible to manipulation of droplet shape.

Two main areas were investigated. First, damage dependence on three mercury conditions - stagnant, flowing, and flowing with bubble injection - was investigated by employing a small mercury target loop with replaceable damage test specimens. One hundred beam pulses were passed through the loop mercury and specimen pair for each test condition. Damage with flowing mercury (V = 0.4 m/s) was less than half that which was incurred with stagnant mercury. Gas bubble injection added into the flow further reduced damage to about one-fourth that of stagnant mercury. Acoustic emissions from cavitation bubble collapse were concurrently measured on the exterior of the loop using a laser Doppler vibrometer and were correlated to the observed damage. The second area of experimentation was erosion rate dependence on proton beam intensity. Prior research had indicated that incubation-phase cavitation erosion rate is strongly dependent on beam intensity, by a power law with the exponent perhaps as large as 4. The 2005 results are inconsistent with earlier in-beam test results and do not support the power law dependence. This paper will provide a detailed description of the experiment, present results and discuss the findings.

The project was initiated in 1999, with groundbreaking in December of 1999. Final integrated system testing for the mercury target, cryogenic moderators, shutter systems, water and other utility systems and all control and safety systems were completed in April 2006 and first beam on target was delivered April 28, 2006. This paper will give an overview of the system testing conducted in preparation for beam operation and initial operating experience with low power beams. One area of testing was extensive remote handling testing in the target service bay to demonstrate all key operations associated with the target and mercury loop. Many improvements were implemented as a result of this experience. Another set of tests involved bringing the supercritical cryogenic moderator systems on line. Again, lessons learned here resulted in system changes. Testing of the four water loops was very time consuming because of the complexity of the systems and many instrumentation issues had to be resolved. A temporary phosphor view-screen was installed on the front of the target which has been extremely useful in evaluating the beam profile on the target. Initial profile results will be presented. Target system performance for initial beam operation will be discussed. In general, all systems performed well with excellent availability. There were some unexpected findings. For example, xenon spallation gas products are believed to have deposited on a downstream gold amalgamation bed designed to remove mercury vapor and this disposition increased the local dose rate. A summary of findings and plans for ramping up in power will be given.

Of the 2,827 putative proteins, 2,026 proteins have predicted functions and 801 are without conserved functional domains, yet 747 of these have similarity to other predicted proteins in databases. Gene homologs from Nitrosomonas europaea and Nitrosomonas eutropha were the best match for 42% of the predicted genes in N. multiformis. The N. multiformis genome contains three nearly identical copies of amo and hao gene clusters as large repeats. The features of N. multiformis that distinguish it from N. europaea include the presence of gene clusters encoding urease and hydrogenase, a ribulose-bisphosphate carboxylase/oxygenase-encoding operon of distinctive structure and phylogeny, and a relatively small complement of genes related to Fe acquisition. Systems for synthesis of a pyoverdine-like siderophore and for acyl-homoserine lactone were unique to N. multiformis among the sequenced genomes of ammonia-oxidizing bacteria. Gene clusters encoding proteins associated with outer membrane and cell envelope functions, including transporters, porins, exopolysaccharide synthesis, capsule formation, and protein sorting/export, were abundant. Numerous sensory transduction and response regulator gene systems directed toward sensing of the extracellular environment are described. Gene clusters for glycogen, polyphosphate, and cyanophycin storage and utilization were identified, providing mechanisms for meeting energy requirements under substrate-limited conditions. The genome of N. multiformis encodes the core pathways for chemolithoautotrophy along with adaptations for surface growth and survival in soil environments.

Tracer transport in the mobile domain is characterized by a travel-time distribution, and mass transfer rates are described by a convolution product of concentrations in the mobile domain and a memory function rather than predefining the mass transfer model. A constant first-order reaction is assumed to occur only in the mobile domain. Analytical solutions in Laplace domain can be derived for both conservative and reactive breakthrough curves (BTCs). Temporal-moment analyses are presented by using the first and second moments of conservative and reactive BTCs and the mass consumption of the reactant for an inverse Gaussian travel-time distribution. In terms of moment matching, there is no need for one to specify the mass transfer model. With the same capacity ratio and the mean retention time, all mass transfer models will lead to the same moment-derived reaction rate coefficients. In addition, the consideration of mass transfer generally yields larger estimations of the reaction rate coefficient than models ignoring mass transfer. Furthermore, the capacity ratio and the mean retention time have opposite influences on the estimation of the reaction rate coefficient: the first-order reaction rate coefficient is positively linearly proportional to the capacity ratio, but negatively linearly proportional to the mean retention time.

2008-096290 AB - The estimation of effective hydraulic parameters of variably saturated layered sediments has been extensively studied using deterministic, stochastic, and combined modeling approaches. Heterogeneity and scale dependence remain as major obstacles, however, for the prediction of water flow and contaminant transport at many U.S. Department of Energy sites. We used a physically based Cantor bar model to describe scale dependence of the fractions of coarse and fine materials in layered sediments. The Cantor bar is determined by three fractal parameters: the subdivision factor, b, the fractal dimension, D, and the iteration level, i, which can be estimated from observation (e.g., borehole logs). Because b and D are scale invariant, the model can be used to predict layering at scales other than the observation scale. Together with a composite medium approximation (COMA), the Cantor bar model can be used to predict effective hydraulic properties as a function of scale. Numerical simulation results showed that COMA works well for steady-state unsaturated flow through a stratigraphic sequence comprised of thin layers of fine material interbedded within a coarse material. Further work is necessary to validate the model predictions by performing measurements at different scales, and to assess the applicability of this approach for transient flow.

This approach allowed relatively rapid reactions to be studied from under- and over-saturation by continuous in situ pH monitoring after addition of basic or acidic titrant, respectively, to a pre-equilibrated, well-stirred suspension of the solid powder. The magnitude of each perturbation was kept small to maintain near-equilibrium conditions. For the case of boehmite, multiple pH-jumps at different starting pHs from over- and under-saturated solutions gave the same observed, first order rate constant consistent with the simple or elementary reaction: Al(OOH) (sub (cr)) +H (sub 2) O (sub (l)) +OH (super -) Al(OH) (sub 4) (super -) . This relaxation technique allowed us to apply a steady-state approximation to the change in aluminum concentration within the overall principle of detailed balancing and gave a resulting mean rate constant, (2.2+ or -0.3)X10 (super -5) kg m (super -2) s (super -1) , corresponding to a 1sigma uncertainty of 15%, in good agreement with those obtained from the traditional approach of considering the rate of reaction as a function of saturation index. Using the more traditional treatment, all dissolution and precipitation data for boehmite at 100.3 degrees C were found to follow closely the simple rate expression: R (sub net,boehmite) = 10 (super -5.485) {m (sub OH-) }{1-exp(Delta G (sub r) /RT)}, with R (sub net) in units of mol m (super -2) s (super -1) . This is consistent with Transition State Theory for a reversible elementary reaction that is first order in OH (super -) concentration involving a single critical activated complex. The relationship applies over the experimental Delta G (sub r) range of 0.4-5.5 kJ mol (super -1) for precipitation and -0.1 to -1.9 kJ mol (super -1) for dissolution, and the pH (sub m) = -log(mH (super +) ) range of 6-9.6. The gibbsite precipitation data at 50 degrees C could also be treated adequately with the same model: R (sub net,gibbsite) = 10 (super -5.86) {m (sub OH-) }{1-exp(Delta G (sub r) /RT)}, over a more limited experimental range of Delta G (sub r) (0.7-3.7 kJ mol (super -1) ) and pH (sub m) (8.2-9.7).

This is mainly due to their ease of application and the more recent advancements incorporating nano-sized generation of particles that find deeper penetration routes and more efficient administration of the drug to specific target organs. Their effectiveness heavily relies on the uniformity of the chemical composition of these aerosolized drugs. Thus, it calls for a real-time on-line analytical tool that can accurately characterize the chemical constituents of the drug powder particles generated to ensure a stringent quality control. We present laser-induced breakdown spectroscopy (LIBS) for the first time as an efficient analytical tool to carry out on-line quantitative chemical characterization of aerosolized drugs. We used three different carbon based aerosolized drugs, namely L-ascorbic acid 2-phosphate sesquimagnesium salt hydrate (C6H9Mg1.5O9P·xH2O), Iron(II) L-ascorbate (C12H14FeO12), and DL-pantothenic acid hemicalcium salt (C9H16NO50.5Ca) for our quantitative LIBS studies here. Our results show that LIBS can effectively estimate the quantitative ratios of carbon to various trace elements for each of these drugs, thereby enabling on-line unique characterization of individual aerosolized drugs. The quantitative LIBS technique predicted the [C]/[Mg], [C]/[Fe], and [C]/[Ca] ratios as 4.02 ± 0.76, 12.42 ± 2.36, and 18.47 ± 4.39 for each of the above aerosolized drugs, respectively. Within error limits, we find these ratios in good agreement with the respective stoichiometric values of 4, 12, and 18 corresponding to the drugs above. Thus, the work demonstrated the utility and validity of LIBS in accurate on-line identification of drug powders during real-time manufacturing processes.

Species that follow a capital-breeding strategy tend to evolve longer intervals between reproductive events and tend to have characteristics that we associate with higher extinction risk. To examine whether these ideas are relevant for fishes, we assembled life history data for fish species, including an index of extinction risk, the interval between spawning events, the degree of parental care, and whether or not the species migrates to spawn. These data were used to evaluate two hypotheses: (1) fish species with a major accessory activity to spawning (migration or parental care) spawn less often and (2) fish species that spawn less often are at greater risk of extinction. We tested these hypotheses by applying two alternative statistical methods that account for phylogenetic correlation in cross-taxon comparisons. The two methods predicted average intervals between spawning events 0.13-0.20 years longer for fishes with a major accessory activity. Both accessories, above-average parental care and spawning migration, were individually associated with longer average spawning intervals. We conclude that the capital-breeding paradigm is relevant for fishes. We also confirmed the second hypothesis, that species in higher IUCN extinction risk categories had longer average spawning intervals. Further research is needed to understand the relationship between extinction risk and spawning interval, within the broader context of life history traits and aquatic habitats.

As-irradiated microstructure was characterized by room-temperature electrical resistivity measurements, transmission electron microscopy (TEM) and positron annihilation spectroscopy (PAS). Tensile tests were carried out between -50 and 100 DGC over the strain rate range 1 X 10-5 to 1 X 10-2 s-1. Fractography was performed by scanning electron microscopy (SEM), and the deformation microstructure was examined by TEM after tensile testing. Irradiation-induced defects became visible by TEM at 0.001 dpa. Both their density and mean size increased with increasing dose. Submicroscopic three-dimensional cavities were detected by PAS even at 0.0001 dpa. The cavity density increased with increasing dose, while their mean size and size distribution was relatively insensitive to neutron dose. It is suggested that the formation of visible dislocation loops was predominantly a nucleation and growth process, while in-cascade vacancy clustering may be significant in Mo. Neutron irradiation reduced the temperature and strain rate dependence of the yield stress, leading to radiation softening in Mo at lower doses. Irradiation had practically no influence on the magnitude and the temperature and strain rate dependence of the plastic instability stress.

This study assembles the tensile test data obtained through multiple irradiation and post-irradiation experiments, in which tensile specimens were irradiated up to 13.1 dpa at 80-1000 DGC and tested at -194 to 1000 DGC. Irradiation at 80-609 DGC increased yield stress significantly, up to 170%, while the increase of yield stress after irradiation at 784-936 DGC was not significant. The plastic instability stress was strongly dependent on test temperature but was nearly independent of irradiation dose and temperature. The true fracture stress showed weak dependences on test temperature, irradiation dose and temperature when ductile failure occurred. Among the test materials the stress-relieved ODS material in the longitudinal direction (ODS-LSR) displayed the highest resistance to irradiation embrittlement due to its relatively high fracture stress. The critical temperature for shear failure (CTSF) was defined and evaluated for the test materials and the CTSF values were compared with the ductile-to-brittle transition temperatures (DBTT) based on ductility data.

After exposure, a small mass gain was measured, indicating that the layer did inhibit dissolution. However, characterization of the external layer determined that it had transformed to LiAlO2 with an increased thickness and a much larger grain size than the original layer. This observation has implications for the use of Al2O3 as a permeation barrier in Pb-Li cooled fusion blanket systems.

Gene expression was quantified at the mRNA level with transcriptomics and at the protein level with quantitative proteomics using super(15)N metabolic labeling. Protein relative abundances, along with their confidence intervals for statistical significance evaluation, were estimated with the software ProRata. Both -omics measurements were used as the transcriptomics provided near-full genome coverage of gene expression profiles and the quantitative proteomics ascertained abundance changes of over 1600 proteins. The integrated gene expression data are consistent with the hypothesis that p-coumarate is converted to benzoyl-CoA, which is then degraded via a known aromatic ring reduction pathway. For the metabolism of p-coumarate to benzoyl-CoA, two alternative routes, a beta -oxidation route and a non- beta -oxidation route, are possible. The integrated gene expression data provided strong support for the non- beta -oxidation route in R. palustris. A putative gene was proposed for every step in the non- beta -oxidation route.

Whereas it has been demonstrated that organic matter has high gas adsorption capacity, the mechanisms and the consequences of this adsorption in subsurface conditions are poorly understood. Small-angle scattering techniques can provide unique, pore-size-specific insight into the density of adsorbed CO (sub 2) . This study reports the results of the first small-angle neutron scattering (SANS) and ultra-small angle neutron scattering (USANS) studies on coal, using the Seelyville Coal from the Illinois Basin as an example. Experimental conditions employed in this work were chosen to simulate a range of coal subsurface conditions including those at 518 feet depth (P,T) = (1-50 bar, 16 degrees C), and the coal was saturated with subcritical CO (sub 2) . Experimental results illustrate that coal microstructure is unaffected by pressurised subcritical CO (sub 2) , and these findings suggest that depths of burial do not constitute a stability barrier to storage of CO (sub 2) . The physical density of CO (sub 2) , fluid phase adsorbed in the porous coal matrix exceeds by a factor of 3-4 the density of the bulk fluid at the same thermodynamic conditions. The applied methodology can be extended to studies of the sorption kinetics and capability of other naturally occurring porous materials of interest for carbon geological storage (saline aquifers, porous rocks, basalts, etc.) as well as investigations of supercritical fluid mixtures (e.g. CO (sub 2) and methane) in various coals.

This perchlorate, which may have both synthetic and natural sources, is problematic from the public health perspective because the highly soluble perchlorate anion is relatively inert and difficult to remove by conventional water treatment methods. We have developed methods to measure the stable isotope ratios of Cl and O in perchlorate, as well as methods to extract and recover measurable amounts of perchlorate from natural waters in which perchlorate concentrations may be in the ppb range. Stable isotope ratios of Cl and O in perchlorate from different sources have been measured, including synthetic perchlorate reagents, natural perchlorate-bearing salt deposits, and perchlorate extracted from various ground water aquifers. These data can clearly distinguish the source(s) of perchlorate in many locations, and can be used to evaluate the extent of in situ microbial perchlorate reduction because of the large and systematic kinetic isotope effects on both O and Cl that have been measured in laboratory cultures. Additional studies are in progress to understand the isotopic diversity of natural perchlorate, which appears to vary geographically.

Computational inference of protein interaction networks and protein complexes from MS data are challenging. Advances are required in developing robust and seamlessly integrated procedures for assessment of protein-protein interaction affinities, mathematical representation of protein interaction networks, discovery of protein complexes and evaluation of their biological relevance. RESULTS: A multi-step but easy-to-follow framework for identifying protein complexes from MS pull-down data is introduced. It assesses interaction affinity between two proteins based on similarity of their co-purification patterns derived from MS data. It constructs a protein interaction network by adopting a knowledge-guided threshold selection method. Based on the network, it identifies protein complexes and infers their core components using a graph-theoretical approach. It deploys a statistical evaluation procedure to assess biological relevance of each found complex. On Saccharomyces cerevisiae pull-down data, the framework outperformed other more complicated schemes by at least 10% in F sub(1)-measure and identified 610 protein complexes with high-functional homogeneity based on the enrichment in Gene Ontology (GO) annotation. Manual examination of the complexes brought forward the hypotheses on cause of false identifications. Namely, co-purification of different protein complexes as mediated by a common non-protein molecule, such as DNA, might be a source of false positives. Protein identification bias in pull-down technology, such as the hydrophilic bias could result in false negatives.

Approximating the seasonal CO sub(2) emission cycle using a 2-harmonic Fourier series with coefficients as a function of latitude, the annual fluxes are decomposed into monthly flux estimates based on data for the United States and applied globally. These monthly anthropogenic CO sub(2) flux estimates are then used to model atmospheric CO sub(2) concentrations using meteorological fields from the NASA GEOS-4 data assimilation system. We find that the use of monthly resolved fluxes makes a significant difference in the seasonal cycle of atmospheric CO sub(2) in and near those regions where anthropogenic CO sub(2) is released to the atmosphere. Local variations of 2-6 ppmv CO sub(2) in the seasonal cycle amplitude are simulated; larger variations would be expected if smaller source-receptor distances could be more precisely specified using a more refined spatial resolution. We also find that in the midlatitudes near the sources, synoptic scale atmospheric circulations are important in the winter and that boundary layer venting and diurnal rectifier effects are more important in the summer. These findings have implications for inverse-modeling efforts that attempt to estimate surface source/sink regions especially when the surface sinks are colocated with regions of strong anthropogenic CO sub(2) emissions.

It is an extracellular commensal, requiring an extract of Thermoproteus tenax for growth, and the genome sequence reveals that biosynthetic pathways for purines, most amino acids, and most cofactors are absent. In fact, T. pendens has fewer biosynthetic enzymes than obligate intracellular parasites, although it does not display other features that are common among obligate parasites and thus does not appear to be in the process of becoming a parasite. It appears that T. pendens has adapted to life in an environment rich in nutrients. T. pendens was known previously to utilize peptides as an energy source, but the genome revealed a substantial ability to grow on carbohydrates. T. pendens is the first crenarchaeote and only the second archaeon found to have a transporter of the phosphotransferase system. In addition to fermentation, T. pendens may obtain energy from sulfur reduction with hydrogen and formate as electron donors. It may also be capable of sulfur-independent growth on formate with formate hydrogen lyase. Additional novel features are the presence of a monomethylamine:corrinoid methyltransferase, the first time that this enzyme has been found outside the Methanosarcinales, and the presence of a presenilin-related protein. The predicted highly expressed proteins do not include proteins encoded by housekeeping genes and instead include ABC transporters for carbohydrates and peptides and clustered regularly interspaced short palindromic repeat-associated proteins.

Large-scale nitrogen budgets show that an average of about 20-25 per cent of the nitrogen added to the biosphere is exported from rivers to the ocean or inland basins, indicating that substantial sinks for nitrogen must exist in the landscape. Streams and rivers may themselves be important sinks for bioavailable nitrogen owing to their hydrological connections with terrestrial systems, high rates of biological activity, and streambed sediment environments that favour microbial denitrification. Here we present data from nitrogen stable isotope tracer experiments across 72 streams and 8 regions representing several biomes. We show that total biotic uptake and denitrification of nitrate increase with stream nitrate concentration, but that the efficiency of biotic uptake and denitrification declines as concentration increases, reducing the proportion of in-stream nitrate that is removed from transport. Our data suggest that the total uptake of nitrate is related to ecosystem photosynthesis and that denitrification is related to ecosystem respiration. In addition, we use a stream network model to demonstrate that excess nitrate in streams elicits a disproportionate increase in the fraction of nitrate that is exported to receiving waters and reduces the relative role of small versus large streams as nitrate sinks.

AN - 70364948; 18320426 AB - The Craig-Gordon model (C-G model) [H. Craig, L.I. Gordon. Deuterium and oxygen 18 variations in the ocean and the marine atmosphere. In Stable Isotopes in Oceanographic Studies and Paleotemperatures, E. Tongiorgi (Ed.), pp. 9-130, Laboratorio di Geologia Nucleare, Pisa (1965).] has been synonymous with the isotope effects associated with the evaporation of water from surface waters, soils, and vegetations, which in turn constitutes a critical component of the global water cycle. On the occasion of the four decades of its successful applications to isotope geochemistry and hydrology, an attempt is made to: (a) examine its physical background within the framework of modern evaporation models, (b) evaluate our current knowledge of the environmental parameters of the C-G model, and (c) comment on a general strategy for the use of these parameters in field applications. Despite its simplistic representation of evaporation processes at the water-air interface, the C-G model appears to be adequate to provide the isotopic composition of the evaporation flux. This is largely due to its nature for representing isotopic compositions (a ratio of two fluxes of different isotopic water molecules) under the same environmental conditions. Among many environmental parameters that are included in the C-G model, accurate description and calculations are still problematic of the kinetic isotope effects that occur in a diffusion-dominated thin layer of air next to the water-air interface. In field applications, it is of importance to accurately evaluate several environmental parameters, particularly the relative humidity and isotopic compositions of the 'free-atmosphere', for a system under investigation over a given time-scale of interest (e.g., hourly to daily to seasonally). With a growing interest in the studies of water cycles of different spatial and temporal scales, including paleoclimate and water resource studies, the importance and utility of the C-G model is also likely to grow in the future.

First, the uncertainties in different emission source categories are discussed and then the results of a base simulation and three sensitivity simulations conducted with a global chemical transport model for mercury (CTM-Hg) are presented. The total Hg emissions in the four scenarios range from 6600 to 9400 Mg/a. The sensitivity studies investigate the impact of the range in uncertainty in natural emissions, emissions of previously deposited Hg, and anthropogenic emissions both in China and worldwide, while taking into account constraints imposed by available data (current/pre-industrial emission ratio of 2-4). In one case, natural emissions and emissions of previously deposited Hg were changed to represent a mid point of the range of values found in the literature. This lead to a 16% increase in background emissions, i.e., natural emissions and emissions of previously deposited Hg combined. Increasing natural emissions by 16% or Chinese anthropogenic emissions by 100% yielded atmospheric Hg concentrations comparable with those measured across the globe without any changes to the atmospheric chemistry. Increasing natural emissions and emissions of previously deposited Hg by 16% and all anthropogenic emissions by 100% as compared to the base scenario yielded atmospheric Hg concentrations that were not compatible with measurements and changes in the chemical behavior of Hg in the atmosphere would be required to yield results that are consistent with observed Hg concentrations. The current uncertainty in total Hg emissions at the global scale is placed at about a factor of two.

Terrestrial landscapes may act as new sources of atmospheric Hg, and as repositories or temporary residences for anthropogenically and naturally derived atmospheric Hg. The role of terrestrial surfaces as sources and sinks of atmospheric Hg must be quantified in order to develop regional and global Hg mass balances, and to assess the efficacy of regulatory controls on anthropogenic point sources in reduction of human Hg exposure. Continued field research has allowed for refinement of emission estimates for geothermal and volcanic, and Hg mineralized areas in the western USA to approximately 1.2-3.0, and 10-20 Mg/a, respectively. The emission estimate for areas of Hg mineralization in the western USA includes only identified Hg deposits and occurrences, and since other areas of geologic Hg enrichment such as Au and Ag deposits are not considered, the range in values is most likely an underestimate. Laboratory and field measurements have improved understanding of air-surface Hg exchange associated with soils with low or natural background concentrations of Hg (<100 ppb), litter-covered forest floors, and foliar surfaces, all of which have large spatial coverage. Deposition of atmospheric Hg and re-emission are important processes occurring at these surfaces on diel and seasonal time scales. Foliage is a significant sink for atmospheric elemental Hg, however, the net flux associated with low Hg containing soils is uncertain. Mass balances developed for soil-air exchange using measured fluxes and estimated deposition indicate that over a year background soils may exhibit no net flux. This suggests that the residence time for elemental Hg in the air is on the order of hours to weeks. Short term exchange would result in a homogenous air Hg concentration due to constant mixing and in an apparent calculated residence time that is most likely too long (one year). Recycling of atmospheric Hg between natural background soils and foliar surfaces also provides a mechanism for long-term atmospheric contamination and continued deposition in pristine ecosystems well after anthropogenic sources are controlled.

This paper summarizes a study carried out for the Pew Center on Global Climate Change that takes a broader look at the potential role of a climate-friendly built environment including not only considerations of how buildings are constructed and used, but also how they interface with the electric grid and where they are located in terms of urban densities and access to employment and services. In addition to summarizing mechanisms of change (barriers and drivers) the paper reviews a set of policies that could bring carbon emissions in the building sector in 2025 almost back to 2004 levels. By the middle of the century the combination of green buildings and smart growth could deliver the deeper reductions that many believe are needed to mitigate climate change.

Using salt-activated enzymes to transform molecules tethered to solid surfaces in organic phase requires solubilization of enzymes in the solvents. Methods of improving performance of salt-lyophilized enzymes, further, via chemical modification, and use of surfactants and surfactants to create fine emulsions prior to lyophilization are investigated. The reaction system used is transesterification of N-acetyl phenylalanine ethyl ester with methanol or propanol. Initial rate of formation of amino acid esters by subtilisin Carlsberg (SC) was studied and found to increase two to sevenfold by either chemical modification or addition of surfactants in certain solvents, relative to the salt (only)-lyophilized enzyme. The method to prepare highly dispersed enzymes in a salt-surfactant milieu also improved activity by two to threefold. To test the effect of chemical modification on derivatization of drug molecules, acylation of bergenin was investigated using chemically modified SC.

He concludes that temporary storage of carbon in the terrestrial biosphere 'achieves effectively no climate-change mitigation'. His strongly worded statement begs for a response. This paper argues that Kirschbaum's conclusion is an artifact of the specific perspective of his analysis and his choice of a definition for climate-change impact. Even temporary sinks put us on a lower path for climate change, a path that will not otherwise be accessible. For carbon sinks in the terrestrial biosphere, we argue that sooner is better and longer is better, but even known temporary sinks have value.

Factors influencing the structuring of microbial communities, including availability of nutrients and water, pH, and soil texture, can vary considerably with soil depth and within soil aggregates. Here we investigated changes in the microbial and functional communities within soil aggregates obtained along a soil profile spanning the surface, vadose zone, and saturated soil environments. The composition and diversity of microbial communities and specific functional groups involved in key pathways in the geochemical cycling of nitrogen, Fe, and sulfur were characterized using a coupled approach involving cultivation-independent analysis of both 16S rRNA (bacterial and archaeal) and functional genes (amoA and dsrAB) as well as cultivation-based analysis of Fe(III)-reducing organisms. Here we found that the microbial communities and putative ammonia-oxidizing and Fe(III)-reducing communities varied greatly along the soil profile, likely reflecting differences in carbon availability, water content, and pH. In particular, the Crenarchaeota 16S rRNA sequences are largely unique to each horizon, sharing a distribution and diversity similar to those of the putative (amoA-based) ammonia-oxidizing archaeal community. Anaerobic microenvironments within soil aggregates also appear to allow for both anaerobic- and aerobic-based metabolisms, further highlighting the complexity and spatial heterogeneity impacting microbial community structure and metabolic potential within soils.

In order to obtain a high quality product, carbon black should remain dispersed during all phases of the gelation process. In this study, the surface and structural properties of several commercial carbon black materials, and the use of dispersing agents was examined with the goal of finding optimal conditions for stabilizing submicron-sized carbon black dispersions. Traditional methods for stabilizing dispersions, based on the use of dispersing agents, failed to stabilize carbon dispersions against large pH variations, typical for the internal gelation process. An alternate dispersing method was proposed, based on using surface-modified carbons functionalized with strongly ionized surface groups (sodium sulfonate). With a proper choice of surface modifiers, these advanced carbons disperse easily to particles in the range of 0.15-0.20 is a subset of m and the dispersions remain stable during the conditions of internal gelation.

These measurements show the effect of varying the deposition conditions, especially the deposition temperature, on the density and optical anisotropy of the carbon layers. Additional heat treatment studies of the coated particles at various stages illustrate the strong effect of post-deposition thermal processing on these two pyrolytic carbon properties. Such post-deposition heat treatment occurs during SiC deposition and fuel compact firing, resulting in increased anisotropy and density of the pyrolytic carbon layers.

AN - 20148195; 8235872 AB - Hydroelectric power provides a cheap source of electricity with few carbon emissions. Yet, reservoirs are not operated sustainably, which we define as meeting societal needs for water and power while protecting long-term health of the river ecosystem. Reservoirs that generate hydropower are typically operated with the goal of maximizing energy revenue, while meeting other legal water requirements. Reservoir optimization schemes used in practice do not seek flow regimes that maximize aquatic ecosystem health. Here, we review optimization studies that considered environmental goals in one of three approaches. The first approach seeks flow regimes that maximize hydropower generation, while satisfying legal requirements, including environmental (or minimum) flows. Solutions from this approach are often used in practice to operate hydropower projects. In the second approach, flow releases from a dam are timed to meet water quality constraints on dissolved oxygen (DO), temperature and nutrients. In the third approach, flow releases are timed to improve the health of fish populations. We conclude by suggesting three steps for bringing multi-objective reservoir operation closer to the goal of ecological sustainability: (1) conduct research to identify which features of flow variation are essential for river health and to quantify these relationships, (2) develop valuation methods to assess the total value of river health and (3) develop optimal control softwares that combine water balance modelling with models that predict ecosystem responses to flow.

The underlying hypothesis is that mild winters and warm, early springs, which are expected to occur as the climate warms, may induce premature plant development, resulting in exposure of vulnerable plant tissues and organs to subsequent late-season frosts. The 2007 spring freeze in the eastern United States provides an excellent opportunity to evaluate this hypothesis and assess its large-scale consequences. In this article, we contrast the rapid prefreeze phenological advancement caused by unusually warm conditions with the dramatic postfreeze setback, and report complicated patterns of freeze damage to plants. The widespread devastation of crops and natural vegetation occasioned by this event demonstrates the need to consider large fluctuations in spring temperatures a real threat to terrestrial ecosystem structure and functioning in a warming climate.

8111874 AB - Nitrogen fixation was measured in constructed old-field ecosystems that were exposed for 3 years to different combinations of elevated atmospheric [CO sub(2)] and temperature (300 ppm and 3 degree C above ambient, respectively), and ambient or reduced soil moisture (corresponding to 25 or 2 mm rainfall per week). The old-fields included seven planted herbaceous annual and perennial species, including two legumes (Trifolium pratense and Lespedeza cuneata). Potential asymbiotic N sub(2)-fixation by soils, measured in laboratory incubations, was significantly less under the "dry" treatment but was estimated to contribute little overall to annual ecosystem N budgets. Foliar N concentrations declined significantly under elevated [CO sub(2)]. Effects of the three environmental factors on the mean ( plus or minus SE) fraction of legume N derived from atmospheric N sub(2) (FN dfa) varied from year-to-year, and FN dfa ranged from 0.64 plus or minus 0.05 to 0.94 plus or minus 0.03 depending on species and growing season. High rates of symbiotic N2-fixation (4.6-12 g N m super(-2) y super(-1)) that annually contributed from 44% to 51% to the aboveground N stock in the old-field community was an important process driving changes in species composition over the 3-year experiment. Lespedeza biomass increased over time at the expense of several other species, including the other N-fixer, Trifolium. The dominance of Lespedeza in our ecosystem was due to high symbiotic N sub(2)-fixation rates, as well as shading effects on other species. The high symbiotic N sub(2)-fixation rates were largely independent of manipulations of [CO sub(2)], temperature, and water. The relatively high percentage of the aboveground N stock in this ecosystem contributed by symbiotic N sub(2)-fixation suggests that non-legume species may have benefited indirectly via reduced community demands on soil N supplies. Species-specific traits were important in the constructed ecosystems, indicating that multi-species studies are required for understanding complex interactions among environmental factors and dynamic changes in community composition.

These autotrophic and mixotrophic sulfur-oxidizing bacteria are believed to contribute substantially to the oxidative portion of the global sulfur cycle. In order to better understand the ecology and roles of sulfur-oxidizing epsilonproteobacteria, in particular those of the widespread genus Sulfurimonas, in biogeochemical cycles, the genome of Sulfurimonas denitrificans DSM1251 was sequenced. This genome has many features, including a larger size (2.2 Mbp), that suggest a greater degree of metabolic versatility or responsiveness to the environment than seen for most of the other sequenced epsilonproteobacteria. A branched electron transport chain is apparent, with genes encoding complexes for the oxidation of hydrogen, reduced sulfur compounds, and formate and the reduction of nitrate and oxygen. Genes are present for a complete, autotrophic reductive citric acid cycle. Many genes are present that could facilitate growth in the spatially and temporally heterogeneous sediment habitat from where Sulfurimonas denitrificans was originally isolated. Many resistance-nodulation-development family transporter genes (10 total) are present; of these, several are predicted to encode heavy metal efflux transporters. An elaborate arsenal of sensory and regulatory protein-encoding genes is in place, as are genes necessary to prevent and respond to oxidative stress.

The model was developed as part of an effort to update the models of the International Commission on Radiological Protection (ICRP) for addressing intakes of radionuclides by workers but is also applicable to environmental or medical exposures to inorganic forms of radiocobalt. The model can be used in conjunction with any respiratory, gastrointestinal, or wound model that provides predictions of the time-dependent feed of cobalt to blood. In contrast to the ICRP's current systemic model for cobalt, which is a simple open catenary system, the proposed model is constructed within a physiologically realistic framework that depicts recycling of cobalt between blood and tissues and transfer from blood to excretion pathways. Compared with the ICRP's current model, the proposed model yields similar predictions of whole-body retention but substantially different predictions of the systemic distribution of cobalt as a function of time after uptake to blood.

Simulations were conducted for 17 locations in the southeastern United States with mean annual temperatures ranging from 13.1 to 19.4 super(o)C. The LINKAGES stand growth model, modified to include the ''RothC'' soil C and soil N model, simulated tree growth and soil C status. Nitrogen fertilization significantly increased cumulative cottonwood aboveground biomass in the three rotations from a site average of 106 to 272Mg/ha in 21 years. The equivalent site averages for loblolly pine showed a significant increase from 176 and 184Mg/ha in 25 years with fertilization. Location results, compared on the annual sum of daily mean air temperatures above 5.5 super(o)C (growing-degree-days), showed contrasts. Loblolly pine biomass increased whereas cottonwood decreased with increasing growing-degree-days, particularly in cottonwood stands receiving N fertilization. The increment of biomass due to N addition per unit of control biomass (relative response) declined in both plantations with increase in growing-degree-days. Average soil C in loblolly pine stands increased from 24.3 to 40.4Mg/ha in 25 years and in cottonwood soil C decreased from 14.7 to 13.7Mg/ha after three 7-year rotations. Soil C did not decrease with increasing growing-degree-days in either plantation type suggesting that global warming may not initially affect soil C. Nitrogen fertilizer increased soil C slightly in cottonwood plantations and had no significant effect on the soil C of loblolly stands.

The distribution of mobile suspended sediments and immobile bed sediments is controlled by hydrologic transport as well as erosion and deposition processes. The fate and transport of water quality constituents involving a variety of chemical and physical processes is mathematically described by a system of reaction equations for immobile constituents and advective-dispersive-reactive transport equations for mobile constituents. To circumvent stiffness associated with equilibrium reactions, matrix decomposition is performed via Gauss-Jordan column reduction. After matrix decomposition, the system of water quality constituent reactive transport equations is transformed into a set of thermodynamic equations representing equilibrium reactions and a set of transport equations involving no equilibrium reactions. The decoupling of equilibrium and kinetic reactions enables robust numerical integration of the partial differential equations (PDEs) for non-equilibrium-variables. Solving non-equilibrium-variable transport equations instead of individual water quality constituent transport equations also reduces the number of PDEs. A variety of numerical methods are investigated for solving the mixed differential and algebraic equations. Two verification examples are compared with analytical solutions to demonstrate the correctness of the code and to illustrate the importance of employing application-dependent numerical methods to solve specific problems.

This warming results primarily from increased concentrations of atmospheric greenhouse gases (GHG), especially CO (sub 2) , emitted from the burning of fossil fuels. The amount of CO (sub 2) currently added to the atmosphere is approximately 30 Gt/yr, and this could double by 2050. Capture and sequestration of CO (sub 2) in deep geological formations-depleted petroleum fields and saline aquifers-is the most plausible option to reduce GHG emissions and mitigate global warming. Geochemical studies, culminating in solute transport modeling, are essential for successful sequestration as they provide an understanding of CO (sub 2) -brine-mineral interactions that determine the long-term storage security and reservoir performance. Reservoir capacity and integrity are strongly affected by the CO (sub 2) trapping mechanisms: 1) As a supercritical and buoyant fluid below a cap rock, "hydrodynamic trapping", and in the pores of reservoir rocks, "residual trapping"; 2) dissolved in formation water as H (sub 2) CO (sub 3) (super o) , HCO (sub 3) (super -) and other species, "solution trapping"; and/or 3) precipitated as calcite, magnesite and siderite, "mineral trapping". Calculations indicate that the bulk of CO (sub 2) will be stored initially as supercritical fluid, because target reservoirs are likely to have T and P values higher than 31 degrees C and 74 bar, the critical values for CO (sub 2) . Formation water contacting the injected CO (sub 2) will rapidly dissolve it to saturation-3-5% of brine weight, depending on its chemical composition and reservoir conditions. Mineral trapping would be slower, but more permanent. Geochemical methods, some novel, were used in the Frio Brine Pilot tests near Houston, Texas to investigate the potential for the storage of CO (sub 2) in saline aquifers. Detailed chemical and isotopic analyses of brine, associated gases, and added tracers proved powerful tools in: 1- Tracking the flow of the injected CO (sub 2) in the injection zone (C-sand); 2-showing that injected CO (sub 2) was not detected in shallow groundwater or at ground level; 3- detecting that some CO (sub 2) leaked into the overlying B-sand that is separated from C by 15 m of shale and siltstone; 4- showing major mobilization of metals (Fe, Pb, etc) and toxic organic compounds (BTEX, PAHs, etc) following CO (sub 2) injection; 5- showing major changes in chemical and isotopic compositions of formation water , including a dramatic drop in calculated brine pH (from 6.3 to 3.0) following CO (sub 2) injection. Geochemical modeling, chemical data and Fe isotopes indicate rapid dissolution of minerals, especially calcite and Fe-oxyhydroxides, and show that some of the Fe and other metal increases were caused by corrosion of well pipe. Geochemical techniques, which have more sensitive natural and added chemical and isotopic tracers than geophysical methods, are recommended for CO (sub 2) injection sites both to assure selection of safe sites and to monitor injection performance.

High-resolution X-ray crystallographic structures of protein complexes can reveal the details of their function and provide a basis for many computational and experimental approaches. Differentiation between biological and non-biological contacts and reconstruction of the intact complex is a challenging computational problem. A successful solution can provide additional insights into the fundamental principles of biological recognition and reduce errors in many algorithms and databases utilizing interaction information extracted from the Protein Data Bank (PDB). Results We have developed a method for identifying protein complexes in the PDB X-ray structures by a four step procedure: (1) comprehensively collecting all protein-protein interfaces; (2) clustering similar protein-protein interfaces together; (3) estimating the probability that each cluster is relevant based on a diverse set of properties; and (4) combining these scores for each PDB entry in order to predict the complex structure. The resulting clusters of biologically relevant interfaces provide a reliable catalog of evolutionary conserved protein-protein interactions. These interfaces, as well as the predicted protein complexes, are available from the Protein Interface Server (PInS) website (see Availability and requirements section). Conclusion Our method demonstrates an almost two-fold reduction of the annotation error rate as evaluated on a large benchmark set of complexes validated from the literature.

We find temperature increases of 3-9oC over Northern India by the end of thiscentury. We will discuss the implications and resulting alterations of the hydrologic cycle as the climate evolvesfrom 2000-2100. In particular, we will assess the changes in the surface latent and sensible heat energy budget, the Indian regional water budgets including trends in the timing and duration of the Indian monsoon and theresulting impacts on mean river flow and hydroelectric power generation potential. These analyses will also beexamined within the context of heat index, droughts, floods and related estimates of societal robustness andresiliency. We will compare our new insights with the existing literature. Climate simulations based on the SRESA2 and B1 scenarios forced with land cover have indicated increased cloud cover and precipitation, resulting indecreased incident radiation and higher latent heat fluxes, in India during June, July and August by 2050(Feddema et al., 2005). Analyses of historical records in the context of the Indian Monsoon Rainfall (IMR) havesuggested an evolving relation of IMR with natural climate variability caused by El Nino events (Krishna Kumar etal., 2006), studied the combined effects of natural climate variability and global warming (Kripalini et al., 2003) onIMR, as well as demonstrated an increasing trend of extreme rain events in a warming environment (Goswami etal., 2006). In addition, the vulnerability of the Indian agriculture sector to climate change was analyzed andmapped at district-levels by combining with multiple global stressors (O'Brien et al., 2004).[[References:::(1) Feddema, J.J., Oleson, K.W., Bonan, G.B., Mearns, L.O., Buja, L.E., Meehl, G.A., and W.M.

The science of data mining is concerned with scaling up of algorithms in statistics, machine learning, nonlinear dynamics, and other data science disciplines, for applications to massive data. Themassive volumes of simulated and remotely sensed data generated by the earth science communities requiredata science algorithms that can scale. Thus, new insights about trends in the statistical properties of heat waves or severe storms at decadal to century time scales may be obtained from observations and climate modelsimulations based on statistical methods applied to specific locations. However, when terabytes of climatemodel scenarios and ensembles generated from IPCC runs need to be analyzed to detect where and when in the global, regional, or local areas change in severe weather patterns are more likely, the problem gets into thepurview of data mining.Earth sciences data are intrinsically spatial and temporal in nature; however, conventional data mining oftenimplicitly assume independence of learning samples. Therefore utilization of techniques from the still emergingfield of spatial and spatio-temporal data mining, which explicitly model spatial and spatiotemporal intricacies,becomes critical. On the other hand, the inherent feedback loops, nonlinear processes and thresholds in climate, meteorology and hydrology may lead to new challenges and research opportunities in spatial and spatio-temporal data mining. In addition to analysis of climate, weather and hydrological observations and modelsimulations, spatial and spatio-temporal knowledge discovery can be useful in understanding, analyzing, andmodeling the impact of extremes or change on critical infrastructures and ecosystems. Thus, while spatialstatistics may not be able to readily determine or utilize the co-occurrence of river networks and electrical grids todetermine the anticipated impact of flooding on electrical power outages, spatial data mining can offer new andinteresting solutions.This is especially true if we view infrastructures or ecosystems as patterns of interconnected systems with spatial and/or functional dependency. These patterns depend on several attributes including the density of populationbeing served, the number of times each infrastructure failure is dependent on the failure of other infrastructures,and the path and intensity of the extreme weather events. For example, the co-location of two or more electricalsubstations along the path of a Tornado will have more impacts on other infrastructures than if the substationsare spatially distant from each other. Spatial data mining techniques can expose other information and revealhidden interdependencies that are useful for inference and accurate predictions. The recent literature in the areaof modeling ecosystems or infrastructure interdependencies under stress often suggests the use of complexadaptive systems. The development of aggregate indicators and similarity measures for infrastructure orecosystem components are required, which in turn can be facilitated by spatial and spatio-temporal data mining.We present a short tutorial on spatial and spatio-temporal data mining, with a particular emphasis on how theycan offer new solutions over and above data science approaches commonly used by the earth science orimpacts communities. We provide preliminary case studies to illustrate the possibilities.

We are developing a C accounting framework that can estimate C dynamics and net emissions associated with changes in land management. One component of this framework integrates field measurements, inventory data, and remote sensing products to estimate changes in soil C and to estimate where these changes are likely to occur at a subcounty (30- by 30-m) resolution. We applied this framework component to a midwestern region of the United States that consists of 679 counties approximately centered around Iowa. We estimated the 1990 baseline soil C to a maximum depth of 3 m for this region to be 4117 Tg. Cumulative soil C accumulation of 70.3 Tg was estimated for this region between 1991 and 2000, of which 33.8 Tg is due to changes in tillage intensity. Without accounting for soil C loss following changes to more intensive tillage practices, our estimate increases to 45.0 Tg C. This difference indicates that on-site permanence of soil C associated with a change to less intensive tillage practices is approximately 75% if no additional economic incentives are provided for soil C sequestration practices. This C accounting framework offers a method to integrate inventory and remote sensing data on an annual basis and to transparently account for alternating annual trends in land management and associated C stocks and fluxes.

The 2007 IPCC report statesthat extreme hydro-meteorological events, ranging from heat waves and cold spells to extreme rainfall events orice storms, are likely to increase in intensity, duration and frequency over the next several decades. While theuncertainties in our current understanding of climate impacts on certain weather extremes like hurricanes may be high, the net damage in the future is expected to increase anyway owing to enhanced stresses caused bypopulation growth and land use changes. The first step is to quantify the expected exacerbation in the intensity-duration-frequency (IDF) of extreme weather and hydrologic events in light of climate change and assess theuncertainties thereof. Climate model projections need to be developed or downscaled at regional to local scalesrelevant to the scales of such hazards and their impacts on infrastructures and their interdependencies. Thesecond step is to quantify the expected impact on infrastructures caused by the exacerbated hazards. Thus,infrastructures designed to outlast specific return levels of precipitation or wind may be under additional stress ifclimate change causes the return levels to intensify. The third step is to develop precise and dynamic geospatialrisk indices. The risk computations need to consider the IDF of weather or hydrologic hazards, aggregatemeasures of infrastructure resilience and vulnerability, the consequences of infrastructure damage onpopulation, economy and environment, and the capabilities and measures that can be brought to bear to mitigatethe risks. One additional requirement is to investigate specific infrastructures in more depth and quantify theincremental stresses on specific failure points. The ultimate goal is to develop decision frameworks to enablestrategic planners as well as specific infrastructure managers analyze and evaluate alternate courses of action,which in turn may range from reinforcing hydraulic structures or developing sensor-based smart infrastructures,to developing redundancy and emergency plans leading to resilience in the face of possible hazards. Thus, what-if capabilities are required to understand root causes, and quantify the value of investments in mitigation oradaptation strategies in terms of cost-benefit analysis, where both short and longer-term costs as well asreduction in risks need to be considered and evaluated. This presentation will describe current and anticipatedresearch at the Oak Ridge National Laboratory in some of these areas.

Magnesium concentration was varied (up to 20 mmol/L) at constant ionic strength (I = 0.101, 0.202, 0.304, 0.406, and 0.509 mol/kg NaNO sub(3)), pH 8.1, total [U(VI)] = 10.4 mu mol/L under equilibrium with atmospheric CO sub(2). The results indicate that only the MgUO sub(2)(CO sub(3)) sub(3) super(2-) complex is formed. The cumulative formation constant extrapolated to zero ionic strength is similar regardless of the activity correction convention used: log beta sub(113) super(0) = 25.8 +/- 0.5 using the Davies equation and = 25.02 +/- 0.08 using specific ion interaction theory (SIT). Uranium sorption onto the exchange resin decreased in the presence of Mg putatively due to the formation of MgUO sub(2)(CO sub(3)) sub(3) super(2-) that had a lower affinity for the resin than UO sub(2)(CO sub(3)) sub(3) super(4-). Uranium sorption results are consistent with an equivalent anion exchange reaction between NO sub(3) super(-) and UO sub(2)(CO sub(3)) sub(3) super(4-) species to retain charge neutrality regardless of Mg concentration. No Mg was associated with the anion exchange resin indicating that the MgUO sub(2)(CO sub(3)) sub(3) super(2-) complex did not sorb.

Conflicting results have been reported with regard to the reliability of microarray results using this method. To explain it, we hypothesize that data processing is a critical element that impacts the data quality. Results Microarray experiments were performed in a g-proteobacterium Shewanella oneidensis. Pair-wise comparison of three experimental conditions was obtained either with two labeled cDNA samples co-hybridized to the same array, or by employing Shewanella genomic DNA as a standard reference. Various data processing techniques were exploited to reduce the amount of inconsistency between both methods and the results were assessed. We discovered that data quality was significantly improved by imposing the constraint of minimal number of replicates, logarithmic transformation and random error analyses. Conclusion These findings demonstrate that data processing significantly influences data quality, which provides an explanation for the conflicting evaluation in the literature. This work could serve as a guideline for microarray data analysis using genomic DNA as a standard reference.

In many bacterial species, coordinate regulation of iron homeostasis depends on the protein product of a Fur gene. Fur also plays roles in virulence, acid tolerance, redox-stress responses, flagella chemotaxis and metabolic pathways. Results We conducted physiological and transcriptomic studies to characterize Fur in Shewanella oneidensis, with regard to its roles in iron and acid tolerance response. A S. oneidensisfur deletion mutant was defective in growth under iron-abundant or acidic environment. However, it coped with iron depletion better than the wild-type strain MR-1. Further gene expression studies by microarray of the fur mutant confirmed previous findings that iron uptake genes were highly de-repressed in the mutant. Intriguingly, a large number of genes involved in energy metabolism were iron-responsive but Fur-independent, suggesting an intimate relationship of energy metabolism to iron response, but not to Fur. Further characterization of these genes in energy metabolism suggested that they might be controlled by transcriptional factor Crp, as shown by an enriched motif searching algorithm in the corresponding cluster of a gene co-expression network. Conclusion This work demonstrates that S. oneidensis Fur is involved in iron acquisition and acid tolerance response. In addition, analyzing genome-wide transcriptional profiles provides useful information for the characterization of Fur and iron response in S. oneidensis.

The collection of these k-mer frequency distributions is unique to each genome and termed the genome's barcode. Results We found that for each genome, the majority of its short sequence fragments have highly similar barcodes while sequence fragments with different barcodes typically correspond to genes that are horizontally transferred or highly expressed. This observation has led to new and more effective ways for addressing two challenging problems: metagenome binning problem and identification of horizontally transferred genes. Our barcode-based metagenome binning algorithm substantially improves the state of the art in terms of both binning accuracies and the scope of applicability. Other attractive properties of genomes barcodes include (a) the barcodes have different and identifiable characteristics for different classes of genomes like prokaryotes, eukaryotes, mitochondria and plastids, and (b) barcodes similarities are generally proportional to the genomes' phylogenetic closeness. Conclusion These and other properties of genomes barcodes make them a new and effective tool for studying numerous genome and metagenome analysis problems.

Background The relationship between the hyperthermophiles Ignicoccus hospitalis and Nanoarchaeum equitans is the only known example of a specific association between two species of Archaea. Little is known about the mechanisms that enable this relationship. Results We sequenced the complete genome of I. hospitalis and found it to be the smallest among independent, free-living organisms. A comparative genomic reconstruction suggests that the I. hospitalis lineage has lost most of the genes associated with a heterotrophic metabolism that is characteristic of most of the Crenarchaeota. A streamlined genome is also suggested by a low frequency of paralogs and fragmentation of many operons. However, this process appears to be partially balanced by lateral gene transfer from archaeal and bacterial sources. Conclusions A combination of genomic and cellular features suggests highly efficient adaptation to the low energy yield of sulfur-hydrogen respiration and efficient inorganic carbon and nitrogen assimilation. Evidence of lateral gene exchange between N. equitans and I. hospitalis indicates that the relationship has impacted both genomes. This association is the simplest symbiotic system known to date and a unique model for studying mechanisms of interspecific relationships at the genomic and metabolic levels.

Using a high resolution modification to the 2-MGEM, it is possible to obtain generalized ellipsometry images of coating layer cross-sections with a pixel size of 2.5 is a subset of m and an optical resolution of 4 is a subset of m. The most important parameter that can be extracted from these ellipsometry images is the diattenuation, which can be directly related to the optical anisotropy factor (OAF or OPTAF) used in previous characterization studies of tristructural isotropic (TRISO) coated particles. Because high resolution images can be obtained, the data for each coating layer contains >6000 points, allowing considerable statistical analysis. This analysis has revealed that the diattenuation of the inner pyrocarbon (IPyC) and outer pyrocarbon (OPyC) coatings varies significantly throughout the layer. The 2-MGEM data can also be used to determine the principal axis angle of the pyrocarbon layers, which is nearly perpendicular to the TRISO radius (i.e., growth direction) and corresponds to the average orientation of the graphene planes.

We used X-ray absorption spectroscopy to determine the valence state and chemical speciation of U in sediment samples collected at a variety of depths through the contaminant plume at the Field Research Center at Oak Ridge, TN, before and after approximately 400 days of in situ biostimulation, as well as in duplicate bioreduced sediments after 363 days of resting conditions. The results indicate that U(VI) in subsurface sediments was partially reduced to 10-40% U(IV) during biostimulation. After biostimulation, U was no longer bound to carbon ligands and was adsorbed to Fe/Mn minerals. Reduction of U(VI) to U(IV) continued in sediment samples stored under anaerobic condition at <4 degree C for 12 months, with the fraction of U(IV) in sediments more than doubling and U concentrations in the aqueous phase decreasing from 0.5-0.74 to <0.1 mu M. A shift of uranyl species from uranyl bound to phosphorus ligands to uranyl bound to carbon ligands and the formation of nanoparticulate uraninite occurred in the sediment samples during storage.

In this study, a tetracycline-inducible small hairpin RNA (shRNA) vector system was designed for silencing cyan fluorescent protein (CFP) expression and delivered alongside the yfp marker gene into Chinese hamster ovary cells using impalefection on spatially indexed vertically aligned carbon nanofiber arrays (VACNFs). The VACNF architecture provided simultaneous delivery of multiple genes, subsequent adherence and proliferation of interfaced cells, and repeated monitoring of single cells over time. Following impalefection and tetracycline induction, 53.1% +/- 10.4% of impalefected cells were fully silenced by the inducible CFP- silencing shRNA vector. Additionally, efficient CFP silencing was observed in single cells among a population of cells that remained CFP-expressing. This effective transient expression system enables rapid analysis of gene- silencing effects using RNAi in single cells and cell populations.

Using argon carrier gas, a HayeSep DB porous polymer phase, and sequential thermal conductivity and reductive gas detectors, the protocol achieved sufficient separation and sensitivity to measure the mixing ratio of all these gases in a single 0.5 mL gas sample collected in situ, stored, transported, and injected using a gastight syringe. Within 4 days of immersion in groundwater, the simple passive in situ sampler, whether initially filled with He or air, attained an equivalent and constant mixing ratio for five of the seven detected gases. The abundant mixing ratio of N sub(2)O, averaging 2.6%, indicated that significant denitrification is likely ongoing within groundwater contaminated with uranium, acidity, nitrate, and organic carbon from a group of four closed radioactive wastewater seepage ponds at the Oak Ridge Field Research Center. Over 1000 passive gas samples from 12 monitoring wells averaged 56% CO sub(2), 32.4% N sub(2), 2.6% O sub(2), 2.6% N sub(2)O, 0.21% CH sub(4), 0.093% H sub(2), and 0.025% CO with an average recovery of 95 +/-14% of the injected gas volume.

Through systematic sampling with active and passive sampling techniques, we found dipnetting to be significantly more effective than three types of passive traps. During surveys for Flatwoods Salamander larvae at Fort Stewart Military Installation, GA in 2005 and 2006, we found that pond residency varied by at least 1.5 months between the 2 years due to the timing of pond filling. In addition, our latest capture on 23 May 2005 was about 2 weeks later than previously recorded at any site range-wide. A simple growth model was used to evaluate likely hatching dates based on significant rain events, observed sizes at capture, and likely growth rates. This analysis suggested that the primary dates of hatching occurred in late February 2005 and early January 2006, a difference that corresponds to that seen in the residency of the latest larval stages. A review of the survey records for Fort Stewart for the past 13 years shows a steep decline in the number of occupied ponds from near 20 to a single pond for the past two years (the only documented breeding success in a natural pond since 1999).

In this paper, we report experimental and modeling results of ferrihydrite colloid release under the influence of citrate species. Using a 3-plane surface complexation model, equilibrium constants were obtained for the three proposed inner-sphere complexes by fitting a citrate adsorption isotherm on ferrihydrite at pH 4, and a pH adsorption envelop with 0.64 mM citrate. The constants were used in a reactive transport model for simulating reaction fronts of dissolved species during injection of citrate in ferrihydrite-coated quartz columns. Simulation results show that sorption alone may not adequately describe the breakthrough curves. Inclusions of ferrihydrite dissolution and re-adsorption of Fe(III) improve the prediction of dissolved species transport. Additionally, matrix diffusion may be needed for improved prediction. For the release of colloidal iron oxides it was shown that both oxide dissolution and interfacial repulsion controlled the process during complete breakthrough. However, the peak release of colloids, which occurred during the actual breakthrough of dissolved species, was mainly brought about by electric double layer forces. These particles underwent detachment-deposition-detachment cycles along the flow path, and emerged in the effluent with the major reaction front. To quantitatively predict colloid release, a semi-empirical linear correlation was established, linking the calculated electric potential to experimental colloid release rates. The model may be applied to the prediction and scaling of aquifer remediation studies involved in the injection of organic ligands to mobilize particle bound contaminants.

Little is known about metal reduction and immobilization under extreme conditions, and only recently bacterial reduction of metals has been demonstrated under extremely alkaline conditions. The objective of this study was to examine metal reduction and mineral formation using an alkaliphilic bacterium, Alkaliphilus metalliredigens (QYMF), isolated from a leachate-pond containing high levels of salt (Na concentration = 440-12,100 mg/L) and boron (2,000-3,000 mg/L) at pH 9.0-10.0. The bacterium was able to use lactate, acetate, and hydrogen as alternative electron donors and Fe(III)-citrate, Fe(III)-ethylenediaminetetraacetate (EDTA), selenate (SeO (sub 4) (super 2-) ), chromate (CrO (sub 4) (super 2-) ), and Co(III)-EDTA as electron acceptors at medium pH = 9.5. The reduction of Fe(III)-citrate and Fe(III)-EDTA in the presence of K (sub 2) HPO (sub 4) and boron resulted in the precipitation of vivianite [Fe (sub 3) (PO (sub 4) ) (sub 2) .8H (sub 2) O]. Formation of sparingly soluble iron phosphates, mediated by the alkaliphilic Fe(III)-reducing bacterium, sequestered iron, phosphate, and other metals into more stable and less toxic forms. These results suggest that bioremediation of metal-contaminated alkaline environments may be feasible, and that the process of metal-reduction may occur in alkaline habitats.

Agricultural practices have environmental impacts that affect a wide range of ecosystem services, including water quality, pollination, nutrient cycling, soil retention, carbon sequestration, and biodiversity conservation. In turn, ecosystem services affect agricultural productivity. Understanding the contribution of various agricultural practices to the range of ecosystem services would help inform choices about the most beneficial agricultural practices. To accomplish this, however, we must overcome a big challenge in measuring the impact of alternative agricultural practices on ecosystem services and of ecosystem services on agricultural production. A framework is presented in which such indicators can be interpreted as well as the criteria for selection of indicators. The relationship between agricultural practices and land-use change and erosion impact on chemical use is also discussed. Together these ideas form the basis for identifying useful indicators for quantifying the costs and benefits of agricultural systems for the range of ecosystem services interrelated to agriculture.

For structured media where preferential flow prevails over the matrix flow, however, the Fe content determined from homogenized samples may not well represent the Fe available for biogeochemical reactions. In this study ammonium oxalate extraction was performed on a core of intact saprolite where physical structure was preserved. An unsaturated flow setup was modified with the intent of allowing the extraction under two pore tensions, 15 and 0 cm of water, although a malfunctioning vacuum regulator made this more difficult than anticipated. Approximately 85% of the oxalate- extractable Fe was contained within the finer pore domain (matrix potential larger than 15 cm). Less than 15.5% of the extracted Fe mass (an upper bound) was present in domains of pore tension less than15 cm. To the extent that Fe(III) oxides play an important role in contaminant biogeochemistry and solute transport, their distribution in structured subsurface media is critical to the understanding of these processes.

However, the effectiveness of hydropower license requirements nationwide has not been demonstrated. One requirement that has become more common is 'run-of-river' (ROR) operation, which restores a natural flow regime. It is widely believed that ROR requirements (1) are mandated to protect aquatic biota, (2) decrease hydropower generation per unit flow, and (3) decrease energy revenue. We tested these three assumptions by reviewing hydropower projects with license-mandated changes from peaking to ROR operation. We found that ROR operation was often prescribed in states with strong water-quality certification requirements and migratory fish species. Although benefits to aquatic resources were frequently cited, changes were often motivated by other considerations. After controlling for climate, the overall change in annual generation efficiency across projects because of the change in operation was not significant. However, significant decreases were detected at one quarter of individual hydropower projects. As expected, we observed a decrease in flow during peak demand at 7 of 10 projects. At the remaining projects, diurnal fluctuations actually increased because of operation of upstream storage projects. The economic implications of these results, including both producer costs and ecologic benefits, are discussed. We conclude that regional-scale studies of hydropower regulation, such as this one, are long overdue. Public dissemination of flow data, license provisions, and monitoring data by way of on-line access would facilitate regional policy analysis while increasing regulatory transparency and providing feedback to decision makers.

Over the last two decades, US biomass forecasts have become increasingly complex and sensitive to environmental and economic considerations; however, more model development and research is needed. In particular, the landscape and regional tradeoffs of differing biofeedstock supplies need to be addressed, especially with regard to water quality concerns and wildlife/biodiversity. Feedstock assessments need to be done in the context of the direction of land-use change induced by biofeedstock production; they need to take into consideration both the starting environmental and economic conditions before the land was used to supply biofeedstocks and the probable future conditions that would result in the absence of biofeedstock production. To evaluate sustainability, process-oriented models need to be coupled or used to inform sector models and more work needs to be done on developing environmental metrics that are useful for evaluating economic and environmental tradeoffs. These challenges are exciting and worthwhile as they will enable the bioenergy industry to capture the environmental and social benefits of biofeedstock production and reduce risks.

The data showed that the response of D. vulgaris to increased pH is generally similar to that of Escherichia coli but is apparently controlled by unique regulatory circuits since the alternative sigma factors (sigma S and sigma E) contributing to this stress response in E. coli appear to be absent in D. vulgaris. Genes previously reported to be up-regulated in E. coli were up-regulated in D. vulgaris; these genes included three ATPase genes and a tryptophan synthase gene. Transcription of chaperone and protease genes (encoding ATP-dependent Clp and La proteases and DnaK) was also elevated in D. vulgaris. As in E. coli, genes involved in flagellum synthesis were down-regulated. The transcriptional data also identified regulators, distinct from sigma S and sigma E, that are likely part of a D. vulgaris Hildenborough-specific stress response system. Characterization of a study set of mutants with genes implicated in alkaline stress response deleted confirmed that there was protective involvement of the sodium/proton antiporter NhaC-2, tryptophanase A, and two putative regulators/histidine kinases (DVU0331 and DVU2580).

Extreme value theory has been widely applied to the hydrologic sciences and hydraulic engineering. However, rigorous approaches to quantify dependence structures among extreme values in space and time have not been reported in the literature. Previous researchers have quantified the dependence among extreme values through the concept of (pairwise bivariate) tail dependence coefficients. For estimation of the tail dependence coefficients, we apply a recently developed method [Kuhn G. On dependence and extremes. PhD thesis (Advisor: C. Kluppelberg), Munich University of Technology, 2006] which utilized the multivariate tail dependence function of a subclass of elliptical copulas. This study extends the previous approach in the context of space and time by considering pairs of spatial grids in South America and quantifying the dependence among precipitation extremes based on the time series at each spatial grid. In addition, Kendall's tau is used to estimate the pairwise copula correlation (for an elliptical copula) of precipitation between all grids in South America. The geospatial-temporal dependence measures are applied to precipitation observations from 1940 to 2005 as well as simulations from the Community Climate System Model version 3 (CCSM3) for 1940-2099. New insights are obtained regarding the spatio-temporal dependence structures for precipitation over South America both with regard to correlation as well as tail dependence.

Each microcosm contained an uranium-contaminated sediment (up to 2.8 g U/kg) suspended in buffer with bicarbonate at concentrations of either 1 or 40 mM and sulfate at either 1.1 or 3.2 mM. Ethanol or acetate was used as an electron donor. Results indicate that ethanol yielded in significantly higher U(VI) reduction rates than acetate. A low bicarbonate concentration (1 mM) was favored for U(VI) bioreduction to occur in sediments, but high concentrations of bicarbonate (40 mM) and sulfate (3.2 mM) decreased the reduction rates of U(VI). Microbial communities were dominated by species from the Geothrix genus and Proteobacteria phylum in all microcosms. However, species in the Geobacteraceae family capable of reducing U(VI) were significantly enriched by ethanol and acetate in low-bicarbonate buffer. Ethanol increased the population of unclassified Desulfuromonales, while acetate increased the population of Desulfovibrio. Additionally, species in the Geobacteraceae family were not enriched in high-bicarbonate buffer, but the Geothrix and the unclassified Betaproteobacteria species were enriched. This study concludes that ethanol could be a better electron donor than acetate for reducing U(VI) under given experimental conditions, and electron donor and groundwater geochemistry alter microbial communities responsible for U(VI) reduction.

TOR-39 AN - 847437626; 13884784 AB - The potentially toxic effects of soluble lanthanide (L) ions, although microbially induced mineralization can facilitate the formation of tractable materials, has been one factor preventing the more widespread use of L-ions in biotechnology. Here, we propose a new mixed-L precursor method as compared to the traditional direct addition technique. L (Nd, Gd, Tb, Ho and Er)-substituted magnetites, L sub(y) Fe sub(3-y) O sub(4) were microbially produced using L-mixed precursors, L sub(x) Fe sub(1-x) OOH, where x=0.01-0.2. By combining lanthanides into the akaganeite precursor phase, we were able to mitigate some of the toxicity, enabling the microbial formation of L-substituted magnetites using a metal reducing bacterium, Thermoanaerobacter sp. TOR-39. The employment of L-mixed precursors enabled the microbial formation of L-substituted magnetite, nominal composition up to L sub(0.06)Fe sub(2.94)O sub(4), with at least tenfold higher L-concentration than could be obtained when the lanthanides were added as soluble salts. This mixed-precursor method can be used to extend the application of microbially produced L-substituted magnetite, while also mitigating their toxicity.

These isotopic values may be used to reconstruct past climate and ecosystems (C3 versus C4 vegetation). Some soils contain large carbonate nodules (>2 cm diameter) that exhibit delta (super 13) C isotopic gradients of up to 2-3 per mil across the nodule and have an internal structure that resembles concentric growth rings. These isotopic gradients are used to potentially track relative nodule movement in soil profiles. Some nodules possibly move within and even across microenvironments displaced by several centimeters. The isotopic gradients of the nodules may also track climate and ecosystem changes associated with relative changes in soil depth caused by soil movement. In order to make accurate climate and ecosystem interpretations, soil organic matter and pedogenic carbonate should be demonstrated to have formed in isotopic equilibrium at their respective soil depth.

All 65 a of data from 1940-2004 are analyzed for spatial variability. The temporal variability is investigated at each spatial grid by utilizing 25-a moving windows from 1965-2004 and visualized through plots of the slope of the regression line in addition to its quality measure (R (super 2) ). The Poisson-generalized Pareto (Poisson-GP) model, which is a peaks over threshold (POT) approach, is applied to weekly precipitation maxima residuals based on the 95%-quantile threshold, while daily data are utilized to analyze the number of consecutive daily extremes and daily extremes in a month based on the 99%-quantile threshold. Using the Poisson-GP model, we compute parameters of the GP distribution, return levels (RL) and a new measure called the precipitation extremes volatility index (PEVI). The PEVI measures the variability of extremes and is expressed as a ratio of return levels. From 1965-2004, the PEVI shows increasing trends in the Amazon basin except eastern parts, few parts of the Brazilian highlands, north-west Venezuela including Caracas, north Argentina, Uruguay, Rio De Janeiro, Sao Paulo, Asuncion, and Cayenne. Catingas, few parts of the Brazilian highlands, Sao Paulo and Cayenne experience increasing number of consecutive 2- and 3-days extremes from 1965-2004. The number of daily extremes, computed for each month, suggest that local extremes occur mostly from December to April with July to October being relatively quiet periods.

Stream water DIN and SRP concentrations in Walker Branch, a first-order deciduous forest stream in eastern Tennessee, show a repeated pattern of annual maxima in summer and biannual minima in spring and autumn. Temporal variations in catchment hydrologic flow paths result in lower winter and higher summer nutrient concentrations, but do not explain the spring and autumn nutrient minima. Ambient nutrient uptake rates were measured 2-3 times per week over an 18-month period and compared to daily rates of gross primary production (GPP) and ecosystem respiration (ER) to examine the influence of in-stream biotic activity on nutrient export. GPP and ER rates explained 81% of the variation in net DIN retention with high net NO sub(3) super(-) uptake (and lower net NH sub(4) super(+) release) rates occurring during spring and autumn and net DIN release in summer. Diel nutrient concentration patterns were examined several times throughout the year to determine the relative importance of autotrophic and heterotrophic activity on net nutrient uptake. High spring GPP corresponded to daily decreases in NO sub(3) super(-) over the illuminated hours resulting in high diel NO sub(3) super(-) amplitude which dampened as the canopy closed. GPP explained 91% of the variance in diel NO sub(3) super(-) amplitude. In contrast, the autumn nutrient minima was largely explained by heterotrophic respiration since GPP remained low and little diel NO sub(3) super(-) variation was observed during the autumn.

First, a conventional approach is to apply ICRP models per se. An alternative method involves individualised fitting of bioassay data using Bayesian statistical methods. A third approach is to develop an independent dosimetry system for Mayak workers by adapting ICRP models using a dataset of available bioassay measurements for this population. Thus, a dataset of 42 former Mayak workers, who died of non-radiation effects, with both urine bioassay and post-mortem tissue data was used to test these three approaches. All three approaches proved to be adequate for bioassay and tissue interpretation, and thus for Pu dose reconstruction purposes. However, large discrepancies are observed in the resulting quantitative dose estimates. These discrepancies can, in large part, be explained by differences in the interpretation of Pu behaviour in the lungs in the context of ICRP lung model. Thus, a careful validation of Pu lung dosimetry model is needed in Mayak worker dosimetry systems.

When CO sub(2) storage is properly measured and taken into account, underestimations of NEE on calm nights can be greatly reduced. Using CO sub(2) data from a 12-level profile at the Missouri Ozark flux site (an oak- hickory forest in central Missouri, USA), we demonstrate that the lower canopy layer (below the thermal inversion) is a disproportionately large contributor to the total CO sub(2) storage. This is because time derivative of CO sub(2) density ([delta]c/[delta]t) generally shows increasing magnitude of mean and standard deviation with decreasing heights at night and from sunrise to 1000 h in both growing and dormant seasons. Effects of resolution and configuration in a profiling system on the accuracy of CO sub(2) storage estimation are evaluated by comparing subset profiles to the 12-level benchmark profile. It is demonstrated that the effectiveness of a profiling system in estimating CO sub(2) storage is not only determined by its number of sampling levels but, more importantly, by its vertical configuration. To optimize a profile, one needs to balance the influence of two factors, [delta]c/[delta]t and layer thickness, among all vertical sections within a forest. As a key contributor to the total CO sub(2) storage, the lower canopy requires a higher resolution in a profile system than the layers above. However, if the upper canopy is oversparsely sampled relative to the lower canopy, the performance of a profile system might be degraded since, in such a situation, the influence of layer thickness dominates over that of [delta]c/[delta]t. We also find that because of different level of complexity in canopy structure, more sampling levels are necessary at our site in order to achieve the same level of accuracy as at a boreal aspen site. These results suggest that in order to achieve an adequate accuracy in CO sub(2) storage measurements, the number of sampling levels in a profile and its design should be subject to the site properties, e.g., canopy architecture and the resulted thermodynamic and flow structures. If CO sub(2) density from a single profile is averaged in time and then used in assessing CO sub(2) storage to reduce random errors, biases associated with this averaging procedure become inevitable. Generally, larger window sizes used in averaging CO sub(2) density generate poorer estimates of CO sub(2) storage. If absolute errors are concerned, it appears that the more significant the CO sub(2) storage is during a period, the larger effects the averaging procedure has. JF - Journal of Geophysical Research.

Direct and nested PCR with specific 16S rRNA gene-targeted primer pairs distinguished strain SZ from other known chlorinated ethene-dechlorinating bacteria and closely related Geobacter isolates, including its closest cultured relative, G. thiogenes. Detection limits for direct and nested PCR were approximately 1 x 10 super(6) and 1 x 10 super(4) 16S rRNA gene copies per mu l of template DNA, respectively. A quantitative real-time PCR (qPCR) approach increased the sensitivity to as few as 30 16S rRNA gene copies per mu l of template DNA but was less specific. Melting curve analysis and comparison of the shapes of amplification plots identified false-positive signals and distinguished strain SZ from G. thiogenes when analyzed separately. These indicators were less reliable when target (strain SZ) DNA and nontarget (G. thiogenes) DNA with high sequence similarity were mixed, indicating that the development of qPCR protocols should not only evaluate specificity but also explore the effects of nontarget DNA on the accuracy of quantification. Application of specific tools detected strain SZ-like amplicons in PCE-dechlorinating consortia, including the bioaugmentation consortium KB-1, and two chlorinated ethene-impacted groundwater samples. Strain SZ-like amplicons were also detected in 13 of 22 groundwater samples following biostimulation at the uranium- and chlorinated solvent-contaminated Integrated Field-Scale Subsurface Research Challenge (IFC) site in Oak Ridge, TN. The numbers of strain SZ-like cells increased from below detection to 2.3 x 10 super(7) plus or minus 0.1 x 10 super(7) per liter groundwater, suggesting that strain SZ-like organisms contribute to contaminant transformation. The G. lovleyi strain SZ-specific tools will be useful for monitoring bioremediation efforts at uranium- and/or chlorinated solvent-impacted sites such as the Oak Ridge IFC site.

S. oneidensis MR-1 can reduce Mn(IV) and Fe(III) oxides and can produce current in microbial fuel cells. The mechanisms that are employed by S. oneidensis MR-1 to execute these processes have not yet been fully elucidated. Several different S. oneidensis MR-1 deletion mutants were generated and tested for current production and metal oxide reduction. The results showed that a few key cytochromes play a role in all of the processes but that their degrees of participation in each process are very different. Overall, these data suggest a very complex picture of electron transfer to solid and soluble substrates by S. oneidensis MR-1.

These inter-site coordinated experiments represent a shift towards research whose goal is to understand how the drivers of ecosystem structure and function change across major continental-scale environmental gradients. LINX consisted of two consecutive, inter-site studies involving super(15)N-tracer additions to streams to determine rates and mechanisms of nitrogen cycling at the scale of entire stream reaches. The LINX studies, which lasted for a decade, were the first to use the super(15)N addition approach to determine gross rates of ammonium and nitrate uptake, nitrification, and denitrification under ambient conditions in stream ecosystems across several biomes and many types of land use. The LINX studies documented the important roles of stream hydrology (flow and transient storage zones), chemistry (N concentrations), and biology (in- stream gross primary production and respiration rates) in controlling N uptake and retention. Stream network models based on field results showed that streams are important sites for N retention in the landscape. Although LINX demonstrated the importance of experiments conducted across stream networks, these studies were limited in duration and could not address questions dealing with long-term impacts. STREON, the stream component of the planned National Ecological Observatory Network (NEON), is intended to use long-term observations and experimental nutrient and consumer organism manipulations to understand controls and forecast changes in stream ecosystems. The observations, to be conducted in a network of more than 20 streams across the U.S. and Puerto Rico over 30 years, will involving state-of-the- art in situ sensors and data communication devices as well as periodic sampling and analyses to determine hydrologic, geomorphologic, biogeochemical, and biological properties and processes. The experiments, to be conducted at about 10 sites over at least 10 years, will involve N and P additions and secondary consumer exclosures to provide a better understanding of how eutrophication and consumer extinction and extirpation, two of the most pervasive forms of environmental change, interact to affect stream ecosystems. Together, the STEON observational and experimental studies will provide critical information on effects of such stresses as climate change, land use change, invasive species, and N deposition on stream ecosystems.

The data are consistent with an oxygen diffusion coefficient of 10 (super -23.5+ or -1) cm (super 2) /s. Furthermore, this gradient is found in a zircon that contains clear textural evidence of recrystallization in nearby regions. This finding shows that through careful textural and chemical analysis, primary information can be extracted from a zircon that has also undergone partial recrystallization. The oxygen isotope ratios found in zircon have been used to infer magmatic and pre-magmatic histories, including the presence of liquid water on the surface of earliest Earth. Recently, these interpretations have been questioned with the assertion that zircon may not retain its primary oxygen isotope signature through metamorphism. The slow diffusion confirmed by these results supports interpretations that assume preservation of magmatic compositions.

Hydrates are potentially large sources of natural gas for human energy needs, directly affect seafloor stability, and play roles in the global carbon cycle and climate change through the release or sequestering of greenhouse gases. However, very little data exists on how hydrates form in nature or where they are likely to accumulate in sediment. Novel meso-scale (10-50 liter) experiments to closely monitor the formation and dissociation of methane hydrates in sediment on a centimeter scale are underway at Oak Ridge National Laboratory's Gas Hydrates Laboratory. Experiments are completed inside the Seafloor Process Simulator (SPS), a 72-L Hastelloy C-22 pressure vessel, which is temperature-controlled inside an explosion-proof cold room. Temperature and strain within the sediment is monitored by a Luna Distributed Sensing System, a fiber optics-based system with data-gathering gratings every 1 centimeter. Total fiber length for any given experiment is at least 4.5 meters. Hydrate formation was observed spatially along three fiber planes within the sediment volume. Hydrate formation and dissociation were first observed along the walls of the chamber, moving inwards through the sediment. Hydrate was observed to form faster and more plentifully near the vessel wall, with formation and dissociation inception times increasing toward the center at rates of 5.5 cm min-1 and 84.4 cm min-1, respectively. Preliminary results also demonstrate the self-limiting effects of hydrate formation. The exothermic reaction raises local temperatures, pushing the system out of the methane hydrate stability field (MHSF), causing hydrate formation to cease before complete transformation of methane and water into hydrate. Subsequent hydrate formation was observed once temperatures dropped to within the MHSF. The results of these experiments can be applied to hydrate formation models as well as natural gas production scenarios from sediment hosted hydrate deposits.

To complement uses of the traditional chemically synthesized magnetite (chem-magnetite) biomagnetite must be exhibit highly reproducible sizes and be available in scalable qualities. Here we emphasize potentially advantageous properties of biomagnetite regarding size, reproducibility and scaling availability. Average crystallite size (ACS) of biomagnetites ranging from 10-100 nm was determined after varied 1) incubation times, 2) substitution of metal and lanthanide species, 3) degrees of congruent incorporation or retardation of substitution elements, 4) bacterial species with their varied ability to substitute elemental species, and 6) incubation temperature that can influence coalescence. The microbial production of biomagnetite has demonstrated capacity to make highly crystalline nanoscale particles of metal-substituted ferrites including compounds of Co, Ni, Cr, Mn, Zn and the rare earths in large quantity. Selected Zn-substituted magnetite (nominal composition of Zn sub(0.6)Fe sub(2.4)O sub(4)) has been recovered at over 1 kg (wet weight) in batches from 30 L fermentations. The massively produced extracellular magnetites were confirmed to exhibit good mono- dispersity via transmission electron microscopy (TEM). TEM also validated highly reproducible ACS of 13.10.8 nm size as determined through X-ray diffraction (N=7) at a 99 % confidence level. Based on the scale-up experiments performed using the 35 L reactor, the reduction in ACS variability and shorted incubation times of several days may be attributed to increases of electron donor input, and availability of divalent ions of the substitution metal with less ferrous ions in the case of doped magnetite, or a combination of the above. While costs of commercial nanometer sized magnetite (25-50 nm) may vary from $500/kg to > $1,000/kg, microbial mass production is likely capable of producing 13-90 nm magnetite or doped magnetites at a fraction of the cost of traditional chemical synthesis. While there are numerous approaches for the synthesis of nanoparticles, bacterial fermentation of magnetite or metal-substituted magnetite may represent a disruptive manufacturing technology with respect to yield, reproducibility and scalability.

Precipitation events and stream flow are analyzed to investigate anticipated changes in the intensity, duration and frequency of extreme events, while land surface wetness is analyzed in conjunction with other variables to anticipate extreme water-related stresses. In particular, changes in projected global population and water availability are compared at high space-time precisions to develop hotspots for water scarcity. Uncertainties in temperature and precipitation are assessed by comparing the CCSM3 model outputs with reanalysis data, which are in turn based on observations and available from the National Centers for Environmental Prediction (NCEP). The possibility of developing uncertainty characterizations for projected stream flow is explored.

In addition to providing accurate morphological information, AFM can be exploited to investigate membrane protein localization and molecular interactions on the surface of living cells. A prerequisite for these studies is the development of robust procedures for sample preparation. While such procedures are established for intact bacteria, they are only beginning to emerge for bacterial spheroplasts. Spheroplasts are useful research models for studying mechanosensitive ion channels, membrane transport, lipopolysaccharide translocation, solute uptake, and the effects of antimicrobial agents on membranes. Furthermore, given the similarities between spheroplasts and cell wall-deficient (CWD) forms of pathogenic bacteria, spheroplast research could be relevant in biomedical research. In this paper, a new technique for immobilizing spheroplasts on mica pretreated with aminopropyltriethoxysilane (APTES) and glutaraldehyde is described. Using this mounting technique, the indentation and cell elasticity of glutaraldehyde-fixed and untreated spheroplasts of E. coli in liquid were measured. These values are compared to those of intact E. coli. Untreated spheroplasts were found to be much softer than the intact cells and the silicon nitride cantilevers used in this study.

Due to their high sequence divergence, sensory domains are difficult to identify. We systematically look for novel sensory domains using sensitive profile-based searches initiated with regions of signal transduction proteins where no known domains can be identified by current domain models. RESULTS: Using profile searches followed by multiple sequence alignment, structure prediction and domain architecture analysis, we have identified a novel sensory domain termed FIST, which is present in signal transduction proteins from Bacteria, Archaea and Eucarya. Chromosomal proximity of FIST-encoding genes to those coding for proteins involved in amino acid metabolism and transport suggest that FIST domains bind small ligands, such as amino acids.

The results were somewhat surprising and indicated that a fundamental assumption in geospatial analysis, namely that variability increases with increasing spatial scale, did not apply for at least five of the 11 soil properties measured over a 0.5-km super(2) area. Composite mineral soil samples (15 cm deep) were collected at 1, 5, 10, 50, 250, and 500 m distances from a center point along transects in a north, south, east, and westerly direction. A null hypothesis of equal variance at different spatial scales was rejected (P[less-than-or-equals, slant]0.05) for mineral soil C concentration, silt content, and the C-to-N ratios in particulate organic matter (POM), mineral-associated organic matter (MOM), and whole surface soil. Results from different tests of spatial variation, based on coefficients of variation or a Mantel test, led to similar conclusions about measurement variability and geographic distance for eight of the 11 variables examined. Measurements of mineral soil C and N concentrations, C concentrations in MOM, extractable soil NH sub(4)-N, and clay contents were just as variable at smaller scales (1-10 m) as they were at larger scales (50-500 m). On the other hand, measurement variation in mineral soil C-to-N ratios, MOM C-to-N ratios, and the fraction of soil C in POM clearly increased from smaller to larger spatial scales. With the exception of extractable soil NH sub(4)-N, measured soil properties in the forest ecosystem could be estimated (with 95% confidence) to within 15% of their true mean with a relatively modest number of sampling points (n[less- than-or-equals, slant]25). For some variables, scaling up variation from smaller to larger spatial domains within the ecosystem could be relatively easy because small-scale variation may be indicative of variation at larger scales.

Though originally developed for NASA, the Mercury development consortium now includes funding from NASA, USGS, and DOE. Mercury supports the reuse of metadata by enabling searching across a range of metadata specification and standards including XML, Z39.50, FGDC, Dublin-Core, Darwin-Core, EML, and ISO-19115. Mercury provides a single portal to information contained in distributed data management systems. It collects metadata and key data from contributing project servers distributed around the world and builds a centralized index. The Mercury search interfaces then allow the users to perform simple, fielded, spatial and temporal searches across these metadata sources. One of the major goals of the recent redesign of Mercury was to improve the software reusability across the 12 projects which currently fund the continuing development of Mercury. These projects span a range of land, atmosphere, and ocean ecological communities and have a number of common needs for metadata searches, but they also have a number of needs specific to one or a few projects. To balance these common and project-specific needs, Mercury's architecture has three major reusable components; a harvester engine, an indexing system and a user interface component. The harvester engine is responsible for harvesting metadata records from various distributed servers around the USA and around the world. The harvester software was packaged in such a way that all the Mercury projects will use the same harvester scripts but each project will be driven by a set of project specific configuration files. The harvested files are structured metadata records that are indexed against the search library API consistently, so that it can render various search capabilities such as simple, fielded, spatial and temporal. This backend component is supported by a very flexible, easy to use Graphical User Interface which is driven by cascading style sheets, which make it even simpler for reusable design implementation. The new Mercury system is based on a Service Oriented Architecture and effectively reuses components for various services such as Thesaurus Service, Gazetteer Web Service and UDDI Directory Services. The software also provides various search services including: RSS, Geo-RSS, OpenSearch, Web Services and Portlets, integrated shopping cart to order datasets from various data centers (ORNL DAAC, NSIDC) and integrated visualization tools.

Climate simulations based on the assumptions implicit in the A1F1 scenario for the period 2000- 2100 using CCSM3 are analyzed. In particular, we will assess the changes in the surface latent and sensible heat energy budget, the Indian regional water budgets including trends in the timing and duration of the Indian monsoon and the resulting impacts on mean river flow and hydroelectric power generation potential. These analyses will also be examined within the context of heat index, droughts, floods and related estimates of societal robustness and resiliency. We will interpret these new A1F1 results within the context of the previous climate simulations based on the SRES A2 and B1 scenarios forced with land cover and atmospheric CO2. Analyses of historical records in the context of the Indian Monsoon Rainfall (IMR) have suggested an evolving relation of IMR with natural climate variability caused by El Nino events. We will report on the combined effects of natural climate variability and global warming on IMR and assess the trend of extreme rain and temperature events in a warming environment.

Most models indicate that injection of CO (sub 2) into deep sedimentary formations will lead to the formation of various carbonate minerals, including the common phases calcite (CaCO (sub 3) ), dolomite (CaMg(CO (sub 3) ) (sub 2) ), magnesite (MgCO (sub 3) ), siderite (FeCO (sub 3) ), as well as the far less common mineral, dawsonite (NaAlCO (sub 3) (OH) (sub 2) ). Nevertheless, the equilibrium and kinetics that control the precipitation of stable carbonate minerals are poorly understood and few experiments have been performed to validate computer codes that model CO (sub 2) sequestration. In order to reduce this uncertainty we measured the solubility of synthetic dawsonite according to the equilibrium: NaAlCO (sub 3) (OH) (sub 2(cr)) + 2H (sub 2) O (sub (l)) Al(OH) (sub 4) (super -) + HCO (sub 3) (super -) + Na (super +) + H (super +) , from under- and oversaturated solutions at 50-200 degrees C in basic media at 1.0 mol.kg (super -1) NaCl. The solubility products (Q (sub s) ) obtained were extrapolated to infinite dilution to obtain the solubility constants (K (sub s) (super o) ). Combining the fit of these logK (sub s) (super o) values and fixing Delta C (sub p,r) (super o) at -185.5 J.mol (super -1) .K (super -1) at 25 degrees C, which was derived from the calorimetric data of Ferrante et al. [Ferrante, M. J., Stuve, J. M., and Richardson, D. W., 1976. Thermodynamic data for synthetic dawsonite. U.S. Bureau of Mines Report Investigation, 8129, Washington, D.C., 13 p.], the following thermodynamic parameters for the dissolution of dawsonite were calculated at 25 degrees C: Delta G (sub r) (super o) = 102.1 kJ.mol (super -1) , Delta H (sub r) (super o) = 97.0 kJ.mol (super -1) and Delta S (sub r) (super o) = -17.1 J.mol (super -1) .K (super -1) . Subsequently, we were able to derive values for the Gibbs energy of formation (Delta (sub f) G (sub 298.15) (super o) = -1782+ or -2 kJ.mol (super -1) ), enthalpy of formation (Delta (sub f) H (sub 298.15) (super o) = -1960+ or -7 kJ.mol (super -1) ) and entropy (S (sub 298.15) (super o) = 131+ or -2 J.mol (super -1) .K (super -1) ) of dawsonite. These results are within the combined experimental uncertainties of the values reported by Ferrante et al. (1976). Predominance diagrams are presented for the dawsonite/boehmite and dawsonite/bayerite equilibria at 100 degrees C in the presence of a saline solution with and without silica-containing minerals.

To test the involvement of Fur in the growth response and transcriptional regulation of D. vulgaris, a targeted mutagenesis procedure was used for deleting the fur gene. Growth of the resulting Delta fur mutant (JW707) was not affected by iron availability, but the mutant did exhibit increased sensitivity to nitrite and osmotic stresses compared to the wild type. Transcriptional profiling of JW707 indicated that iron-bound Fur acts as a traditional repressor for ferrous iron uptake genes (feoAB) and other genes containing a predicted Fur binding site within their promoter. Despite the apparent lack of siderophore biosynthesis genes within the D. vulgaris genome, a large 12-gene operon encoding orthologs to TonB and TolQR also appeared to be repressed by iron-bound Fur. While other genes predicted to be involved in iron homeostasis were unaffected by the presence or absence of Fur, alternative expression patterns that could be interpreted as repression or activation by iron-free Fur were observed. Both the physiological and transcriptional data implicate a global regulatory role for Fur in the sulfate-reducing bacterium D. vulgaris.

The daunting prospect of complete nitrate removal prior to the reduction of uranium provides a strong incentive to explore bioremediation strategies that allow for uranium bioreduction and stabilization in the presence of nitrate. Typical in situ strategies involving the stimulation of metal-reducing bacteria are hindered by low-pH environments and require that the persistent nitrate must first and continuously be removed or transformed prior to uranium being a preferred electron acceptor. This work investigated the possibility of stimulating nitrate-indifferent, pH-tolerant microorganisms to achieve bioreduction of U(VI) despite nitrate persistence. Enrichments from U-contaminated sediments demonstrated nearly complete reduction of uranium with very little loss of nitrate from pH 5.7-6.2 using methanol or glycerol as a carbon source. Bacterial 16S rRNA genes were amplified from uranium-reducing enrichments (pH 5.7-6.2) and sequenced. Phylogenetic analyses classified the clone sequences into four distinct clusters. Data from sequencing and terminal-restriction fragment length polymorphism (T-RFLP) profiles indicated that the majority of the microorganisms stimulated by these enrichment conditions consisted of low G+C Gram-positive bacteria most closely related to Clostridium and Clostridium-like organisms. This research demonstrates that the stimulation of a natural microbial community to immobilize U through bioreduction is possible without the removal of nitrate.

Atom probe tomography has been used to demonstrate the importance of the post weld stress relief treatment in reducing the matrix copper content in high copper alloys, the formation of 2-nm-diameter copper-, nickel-, manganese- and silicon-enriched precipitates during neutron irradiation in copper containing RPV steels, and the coarsening of these precipitates during post irradiation heat treatments. Atom probe tomography has been used to detect 2-nm-diameter nickel-, silicon- and manganese-enriched clusters in neutron irradiated low copper and copper free alloys. Atom probe tomography has also been used to quantify solute segregation to, and precipitation on, dislocations and grain boundaries.

Reactor conditions for several designs offer challenges for engineers and designers concerning which structural and cladding materials to use. Depending on operating conditions, some of the designs favor the use of elevated-temperature ferritic/martensitic steels for in-core and out-of core applications. This class of commercial steels has been investigated in previous work on international fast reactor and fusion reactor research programs. More recently, international fusion reactor research programs have developed and tested elevated-temperature reduced-activation steels. Steels from these fission and fusion programs will provide reference materials for future fission applications. In addition, new elevated-temperature steels have been developed in recent years for conventional power systems that also need to be considered for the next generation of nuclear reactors.

NBG-10 graphite was developed as a candidate core structural material for the pebble bed modular reactor (PBMR) currently being designed in South Africa, and for prismatic reactor concepts being developed in the USA and Europe. NBG-10 is one of several graphites included in the US-DOE Very High Temperature Reactor (VHTR) program. Thirty-six NBG-10 graphite flexure bars have been successfully irradiated in a series of 18 HFIR PTT capsules at ORNL. The capsule irradiation temperatures were 294 - 25, 360 - 25 and 691 - 25 DGC. The peak doses attained were 4.93, 6.67, and 6.69 X 1025 n/m2 [E > 0.1 MeV] at 294, 360, and 691 DGC, respectively. The high temperature irradiation volume and dimensional change behavior, and flexure strength and elastic modulus changes of NBG-10 were similar to other extruded, near-isotropic grades, such as H-451, which has been irradiated previously at ORNL. The low temperature (294 DGC) irradiation volume and dimensional change behavior was also as expected for extruded graphites, i.e., exhibiting low dose swelling prior to shrinkage. This behavior was attributed to the relaxation of internal stress arising from the graphite manufacturing process and specimen machining. While the data reported here do not represent a complete database for NBG-10 graphite, they give a measure of confidence that the current generation of nuclear graphites will behave in a familiar and well understood manner.

While there has been significant developmental work on manufacturing the fuel particles, detailed understanding of the effects of the complex in-service stress state combined with realistic materials property data under irradiation on fuel particle survival is not adequately understood. This particularly frustrates the modeling efforts that seek to improve fuel performance through basic understanding. In this work a compilation of non-irradiated and irradiated properties of SiC are provided and reviewed and analyzed in terms of application to TRISO fuels. In addition to a compilation and review of literature data, new data generated to fill holes in the existing database is included, specifically in the high-temperature irradiation regime. Another critical piece of information, the strength of the SiC/Pyrolytic carbon interface, was measured and is included, along with a formalism for its analysis. Finally, recommended empirical treatments of the data are suggested.

The mixed-oxide fuel was fabricated at Los Alamos National Laboratory by a master-mix process and has been irradiated in the advanced test reactor at the Idaho National Laboratory. Previous withdrawals of the same fuel have occurred at 9, 21, 30, and 40 GWd/MT. Oak Ridge National Laboratory manages this test series for the Department of Energy's Fissile Materials Disposition Program. This paper describes the preparation of the mixed-oxide fuel, the equipment design, and the irradiation history of the test capsules, and discusses the significance of the more important observations of the post-irradiation examinations. Code predictions (FRAPCON-3 and TRANSURANUS) are presented and compared with available post-irradiation examination data for the highest and lowest powered mixed-oxide capsules. Fuel performance has been excellent and consistent with code predictions and with existing US and European experience.

In this study, a micro-indentation fiber push-out test was applied to measure the interfacial shear properties of a model TRISO-coated tube. Of particular emphasis is that this study developed a non-linear shear-lag model for a transversely isotropic composite material due to insufficiency in the existing isotropic models as applied to layered TRISO-coating systems. In the model, the effects of thermal residual stresses and the roughness-induced clamping stress were identified as particularly important. The rigorous model proposed in this study provides more reasonable data on two important interfacial parameters: the interfacial debond shear strength and the interfacial friction stress. The modified model coupled with experiments yields an interfacial debond shear strength of 240 - 40 MPa. This high interfacial strength, though slightly lower than that obtained by the existing isotropic model (280 MPa), allows significant loads to be transferred between inner PyC and SiC in application. Additionally, an interfacial friction stress of 120 - 30 MPa was determined. This high friction stress is attributed primarily to the roughness at the cracked interface rather than clamping effects due to differing coefficients of thermal expansion.

Irradiated Mo was tensile tested over a temperature range of -50 to 100 DGC at a strain rate of 1 X 10-3 s-1. It was found that the yield stress of irradiated Mo decreased at lower temperatures and increased at higher temperatures, resulting in reduced temperature dependence of yielding at lower doses (0.001 dpa). The temperature dependence of the yield stress for unirradiated and irradiated Mo is consistent with the theoretical expression of the Fleischer model for interactions of dislocations with tetragonal strain fields.

The materials used were chemical vapor deposition (CVD) SiC and SiC/SiC composites reinforced with either Hi-Nicalon(TM) Type-S, Hi-Nicalon(TM) or Sylramic(TM) fibers fabricated by chemical vapor infiltration. A statistically significant population of flexural samples were irradiated up to 4.6 X 1025 n/m2 (E > 0.1 MeV) at 300, 500, and 800 DGC in the High Flux Isotope Reactor at Oak Ridge National Laboratory. Dimensions and weights of the flexural bars were measured before and after the neutron irradiation. Mechanical properties were evaluated by four point flexural testing. Volume increase was seen for all bend bars following neutron irradiation. The magnitude of swelling depended on irradiation temperature and material, while it was nearly independent of irradiation fluence over the fluence range studied. Flexural strength of CVD SiC increased following irradiation depending on irradiation temperature. Over the temperature range studied, no significant degradation in mechanical properties was seen for composites fabricated with Hi-Nicalon(TM) Type-S, while composites reinforced with Hi-Nicalon(TM) or Sylramic fibers showed significant degradation. The effects of irradiation on the Weibull failure statistics are also presented suggesting a reduction in the Weibull modulus upon irradiation. The cause of this potential reduction is not known.

nanophase metallic Fe synthesis AN - 51375650; 2007-101948 AB - Lunar regolith contains important materials that can be used for in-situ resource utilization (ISRU) on the Moon, thereby providing for substantial economic savings for development of a manned base. However, virtually all activities on the Moon will be affected by the deleterious effects of the adhering, abrasive, and pervasive nature of lunar dust (<20 mu m portion of regolith, which constitutes approximately 20 wt% of the soil). In addition, the major impact-produced glass in the lunar soil, especially agglutinitic glass (60-80 vol% of the dust), contains unique nanometer-sized metallic Fe (np-Fe (super 0) ), which may pose severe pulmonary problems for humans. The presence of the np-Fe (super 0) imparts considerable magnetic susceptibility to the fine portion of the lunar soil, and dust mitigation techniques can be designed using these magnetic properties. The limited availability of Apollo lunar soils for ISRU research has made it necessary to produce materials that simulate this unique np-Fe (super 0) property, for testing different dust mitigation methods using electromagnetic fields, and for toxicity studies of human respiratory and pulmonary systems, and for microwave treatment of lunar soil to produce paved roads, etc. A method for synthesizing np-Fe (super 0) in an amorphous silica matrix is presented here. This type of specific simulant can be used as an additive to other existing lunar soil simulants.

Good agreement was observed in the iron beta -factors of metallic iron (alpha -Fe) and hematite calculated using both Moessbauer- and INRXS-derived data, which supports the validity and reliability of the calculations. Based on this excellent agreement, we suggest the use of the present data on the iron beta -factors of hematite as a reference. The previous Moessbauer-derived iron beta -factor for magnetite has been modified significantly based on the Fe-sublattice density of states obtained from the INRXS experiments. This resolves the disagreement between naturally observed iron isotope fractionation factors for mineral pairs involving magnetite and those obtained from the calculated beta -factors. The correctness of iron beta -factor for pyrite has been corroborated by the good agreement with experimental data of sulfur isotope geothermometers of pyrite-galena and pyrite-sphalerite. A good correlation between the potential energy of the cation site, the oxidation state of iron and the iron beta -factor value has been established. Specifically, ferric compounds, which have a higher potential energy of iron than ferrous compounds, have higher beta -factors. A similar dependence of beta -factors on the oxidation state and potential energy could be extended to other transition metals. Extremely low values of INRXS-derived iron beta -factors for troilite and Fe (sub 3) S significantly widen the range of iron beta -factors for covalently bonded compounds.

Deformation-induced martensite transformation and dislocation channeling were observed at irradiation dose higher than 0.1 dpa. Estimation of the resolved shear stress (RSS) associated with each dislocation channel indicated a tendency for the RSS and channel width to be greatest when the angle between tensile axis and slip plane normal is around 45DG. Furthermore, channel width increased with increasing RSS, indicating that the most extensive localized channel deformation tends to occur at a high RSS level. Deformation-induced martensite phase was found at various strain levels even at room temperature and tends to be exhibited mainly at intersections of channels. This suggests that a very high stress could lead to the gamma -> alpha martensite formation by the spreading of a Shockley partial dislocation over successive 1 1 1fcc planes.

The stress-strain behavior of the multilayered interphase composites remained unmodified after irradiation. The PyC interphase composite increased in ultimate tensile stress and strain to failure following neutron irradiation, whereas the proportional limit stress exhibited a slight decrease. Potential mechanisms for these changes include accommodation of misfit stress through irradiation creep, reduced interfacial friction, and differential swelling among individual composite constituents.

Tensile specimens machined from the alloys were tested at room temperature and at temperatures ranging from 360 DGC to 800 DGC in air using a strain rate of 10-3 s-1. The results showed that the high-temperature strength of the NC strengthened alloys was significantly better than that of the oxide strengthened alloys. The room temperature yield strengths of the two alloys containing the NC were 1469 MPa and 1261 MPa while the yield strengths of the two oxide dispersion alloys were 819 MPa (Y-Ti-oxides) and 583 MPa (Ti-oxides). However, the ductility of the oxide strengthened alloys was better than that of the NC strengthened alloys.

As the first step in determining the long-term compatibility of SiC/SiC in Pb-Li, specimens of high-purity, chemical vapor deposited (CVD) SiC were exposed in capsules for up to 5000 h at 800 DGC and 1000 h at 1200 DGC. Dissolved Si was detected in the Pb-Li after the highest temperature exposures suggesting that SiC may be limited to <1100 DGC in Pb-Li. Aluminide coatings are being considered for corrosion resistant coatings for the tubing between the first wall and the heat exchanger. Initial results indicate that, in Pb-Li at 700 DGC, FeCrAl, Fe3Al and NiAl form a protective alumina layer which reduces dissolution compared to type 316 stainless steel.

Small (12.5 mm in diameter with thickness of 4.6 mm) disk-shaped compact tension specimens were irradiated at average temperatures of 250 DGC and 377 DGC to 4 dpa. Small, 3.33 X 3.33 X 25 mm, pre-cracked Charpy specimens were irradiated at 300 DGC and 500 DGC to 5 dpa. Transition fracture toughness was evaluated in terms of the reference temperature T0 for each irradiation temperature and dose and compared to unirradiated T0. Current fracture toughness shifts compared with T0 shifts of F82H and 9Cr2WVTa steels irradiated at similar conditions. The present results show that JLF-1, F82H, and 9Cr-2WVTa steels have very similar resistance to radiation embrittlement after doses of 4-5 dpa in the temperature range from 250 DGC to 500 DGC.

During intermediate annealing at 1000 DGC in the 10-4 Torr vacuum regime, oxygen penetration into the tube wall is controlled by the development of a semi-protective surface oxide (linear-parabolic oxidation conditions); oxygen-hardened surface layers lead to a high incidence of surface cracking during the final stages of cold drawing. In the 10-5 Torr regime, under linear kinetic oxidation conditions, rapid oxygen penetration results in unacceptably high levels of oxygen pick-up (1500 wppm). In the 10-7 Torr vacuum regime, molecular impingement rates are reduced to the point where overall oxygen pick-up is reduced to <100 wppm. Improved cleaning/gettering procedures also restrict carbon and nitrogen pick-up to very low levels.

A constant bend strain was applied to thin strip samples during neutron irradiation to fluences 0.2-4.2 dpa at various temperatures in the range 400 to 1080 DGC. Irradiation creep strain at 0.7 dpa were estimated to be 2.7(-2.6) X 10-7 and 1.5(-0.8) X 10-6 (MPa dpa)-1 at 600 to 950 DGC and 1080 DGC, respectively, whereas linear-averaged creep compliances of 1-2 X 10-6 (MPa dpa)-1 were obtained for doses of 0.6-0.7 dpa at all temperatures. Monocrystalline 3C SiC samples exhibited significantly smaller transient creep strain and greater subsequent deformation when loaded along 0 1 1 direction.

The materials investigated were Hi-Nicalon(TM) Type-S fiber reinforced chemically vapor infiltrated SiC matrix composites with varied interphases: monolayered pyrolytic carbon (PyC) or multilayered PyC/SiC. The neutron fluence was 7.7 X 1025 n/m2 (E > 0.1 MeV), and the irradiation temperature was 800 DGC. Interfacial shear properties were evaluated by the fiber push-out test method. A modified shear-lag model was applied to analyze the interfacial shear parameters. Test results indicate that the interfacial debond shear strength and the interfacial friction stress for the multilayer composites were significantly degraded by irradiation. Nevertheless, the multilayer composites retained sufficient interfacial shear properties so that overall composite strength after neutron irradiation was unaffected. The actual mechanism of interphase property decrease for the multilayer composites is unknown. The interfacial shear properties of the irradiated monolayer composites appear unaffected.

Materials were irradiated in a range of temperature from 200 to 1500 DGC and from a fraction of a dpa to 6 dpa. Data on swelling and room temperature thermal conductivity are presented. The swelling behavior below 800 DGC agrees well with the literature values. Data in the range of 1000-1600 DGC indicates that swelling increases as the dose is increased from 2 dpa to 6 dpa, at higher-swelling with increasing irradiation temperature. Any peak in void swelling apparently occurs at irradiation temperature >1500 DGC (>0.6Tm). In the 1100-1200 DGC temperature range, volumetric swelling is apparently at a minimum though increases from 0.2% to 0.4% as dose increases from 2 dpa to 6 dpa. The maximum swelling was found to be 1.5% at the maximum dose and temperature of this study, 6 dpa and 1500 DGC. Room temperature thermal conductivity data over the entire temperature range are presented and a direct correlation between the thermal defect resistance and swelling is seen for materials irradiated at temperature less than 800 DGC. Above 1000 DGC the correlation between swelling and thermal defect resistance breaks down indicating a changing microstructure at high temperature to a microstructure less effective at scattering phonons on a swelling-normalized basis.

Within this program, three capsules containing a variety of specimen designs were irradiated at two design temperatures in the ORNL High Flux Isotope Reactor (HFIR). Two capsules, RB-11J and RB-12J, were irradiated in the HFIR removable beryllium positions with europium oxide (Eu2O3) thermal neutron shields in place. Specimens were irradiated up to 5 dpa. Capsule JP25 was irradiated in the HFIR target position to 20 dpa. The design temperatures were 300 DGC and 500 DGC. Precracked third-sized V-notch Charpy (3.3 X 3.3 X 25.4 mm) and 0.18 T DC(T) specimens were tested to determine transition and ductile shelf fracture toughness before and after irradiation. The master curve methodology was applied to evaluate the fracture toughness transition temperature, T0. Irradiation induced shifts of T0 and reductions of JQ were compared with Charpy V-notch impact properties. Fracture toughness and Charpy shifts were also compared to hardening results.

In this paper, the experience gleaned from previous programs to develop materials for high temperature structural applications is used to identify and discuss some of the most critical issues that must be addressed in the development of candidate materials for fusion structural applications. Critical issues discussed include radiation-induced solute segregation and implications on phase stability in the development of high-performance alloys/ceramics; the effects of very large amounts of helium on mechanical properties and the implications for alloy design/development; development of high temperature design methodology and incorporation of radiation effects into this methodology; the effects of radiation damage on flow localization, and the implications and approach to control the phenomena; and considerations of mass transfer and corrosion in complex fusion systems.

The potential for these materials have been widely discussed and is now understood to be (1) the ability to operate in temperature regimes much higher than for metallic alloys, (2) an inherent low level of long-lived radioisotopes that reduces the radiological burden of the structure, and (3) perceived tolerance against neutron irradiation up to high temperatures. This paper reviews the recent progress in development, characterization, and irradiation effect studies for SiC composites for fusion energy applications. It also makes the case that SiC composites are progressing from the stage of potential viability and proof-of-principle to one where they are ready for system demonstration, i.e., for flow channel inserts in Pb-Li blankets. Finally, remaining general and specific technical issues for SiC composite development for fusion applications are identified.

Both the formation and relaxation energies of single He defects and small He clusters were accounted for in the fitting process. The new potential consists of a repulsive pair-potential term and a three-body interaction term, and was applied in combination with three commonly used iron interatomic potentials, and a potential describing the behavior of helium in vacuum. As an application of the new potential, the stability of He-vacancy clusters at zero temperature was evaluated. The calculated results were similar for all three Fe potentials, and the new potentials provide results that are more consistent with ab initio calculations than those obtained from previous Fe-He potentials.

Based on the science of precipitate strengthening, a thermo-mechanical treatment (TMT) was developed that increased the strength from room temperature to 700 DGC of commercial nitrogen-containing steels and new steels designed for the TMT. At 700 DGC increases in yield stress of 80 and 200% were observed for a commercial steel and a new steel, respectively, compared to commercial normalized-and-tempered steels. Creep-rupture strength was similarly improved. Depending on the TMT, precipitates were up to eight-times smaller at a number density four orders of magnitude greater than those in a conventionally heat treated steel of similar composition.

Post-irradiation examination included electrical resistivity and tensile properties measured at room temperature. Microstructure of irradiated specimens was examined by TEM and the defect cluster density and cluster mean size were characterized. Measurements of electrical resistivity and cluster density showed sublinear defect accumulation behavior. The mean size of visible defect clusters increased with increasing dose. Yield stress decreased at 7.2 X 10-5 and 7.2 X 10-4 dpa, then increased significantly with increasing dose up to 0.072 dpa and saturated. It appeared that there was a transition in hardening from weak obstacles to strong obstacles. It is suggested that the formation of sessile defect clusters in neutron-irradiated Mo is mainly associated with diffusive nucleation and growth rather than in-cascade clustering.

Specimens were tested at several temperatures in the transition region with at least four tests at each temperature to allow application of the Weibull statistic/master curve analysis procedure. The largest specimens were 1 T C(T) compact specimens. Broken halves of 1 T C(T) specimens were later used to machine and test smaller, 0.4 T C(T) and 0.18 T DC(T), specimens more suitable for irradiation experiments. The scatter of fracture toughness was rather high relative to scatter predicted by conventional master curve concept, but was similar for larger and smaller specimens. It was assumed that this material exhibited inhomogeneity of fracture toughness. Random inhomogeneity analysis provides a very good description of the scatter of fracture toughness data of F82H steel. At the same time, values of T0 derived using conventional and random inhomogeneity analyses are similar. TEM and SEM analysis helped identify microstructural features that might be responsible for such behavior.

A single crystal iron sample was irradiated at 60 DGC in the High Flux Isotope Reactor at the Oak Ridge National Laboratory to a fluence of 1 X 1023 n/m2 (E > 0.1 MeV), or 0.01 dpa. Diffuse X-ray scattering measurements were carried out at the Advanced Photon Source at the Argonne National Laboratory on three specimens: unirradiated, as-irradiated, and irradiated and annealed for one hour at 450 DGC (IA). The specimens were cooled to 40 K to minimize thermal diffuse scattering. Subsequent measurements of the specimen lattice parameter were completed at ORNL. The diffuse scattering in the as-irradiated specimen was dominated by interstitial defect clusters exhibiting a tetragonal distortion consistent with a 1 0 0 type defect. Substantial recovery of this defect component was observed following the anneal at 450 DGC. A lattice parameter increase was observed following irradiation, which is also consistent with a substantial population of interstitial type defects. A net lattice parameter decrease was observed in the IA specimen, indicating loss of the interstitial defects with a residual population of vacancy-type defects.

In this paper, the fracture toughness and tensile properties of an ODS steel with nominal composition Fe-12Cr-2.5W-0.4Ti-0.25Y2O3 (designated 12YWT) were investigated and compared to commercial reduced-activation ferritic/martensitic (RAFM) steels. Small, 1.6-mm thick and 3.2-mm wide, 3-point bend specimens were used for fracture toughness characterization of this steel. Specimens were fatigue pre-cracked to initial crack length (a) to width (W) ratio of 0.45 and tested quasi-statically in the temperature range from -50 DGC to 550 DGC. Specimens tested up to 50 DGC exhibited elastic-plastic cleavage fracture that was typical for the transition region in ferritic steels. The master curve transition temperature, T0, for the 12YWT alloy was determined to be 102 DGC. Specimens tested at 100 DGC and higher exhibited ductile stable crack growth. In these cases, the J-integral at the onset of stable crack growth (JIc) was determined from the J-R curves. Their equivalent values in terms of stress intensity factor, KJIc, were about 93 MPa√ m at 100 DGC and decreased to 53 MPa√ m at 550 DGC. This study showed that oxide dispersion strengthening resulted in significant decreases in the toughness properties compared to commercial RAFM steels, although appreciable level of toughness was still retained. Tensile tests were performed at temperatures between room temperature and 800 DGC. As expected, this material exhibited very high yield strength, 1300 MPa, at room temperature. For comparison, the yield strength of commercial RAFM steels is about 550 MPa. Yield strength of 12YWT decreases as test temperature increases and at 800 DGC it is about 323 MPa.

Individual TEM images of Frank loops formed on each {1 1 1} plane revealed that their population strongly depended upon their orientation with respect to the incident beam direction. However, no significant difference in loop growth rates was observed between each habit plane. The anisotropic loop evolution has not been reported for neutron-irradiated SiC. Our examination shows that a grain, containing {1 1 1} planes nearly parallel to the irradiated surface, was largely strained toward the free surface by the preferential formation of Frank loops on the plane. Compressive stress following the anisotropic swelling in ion-irradiated specimen may affect the loop evolution. The possible mechanism of the anisotropic loop evolution observed here is accounted for by the stress induced preferential nucleation of Frank loops.

In the first method hoop stress is applied to a thin-walled tubular specimen by internal pressurization using a polyurethane insert. The second method is a crushing technique, in which tubular specimen is fractured by diametrical compressive loading. Tubular SiC specimens with a wall thickness of about 100 is a subset of m and inner diameters of about 0.9 mm (SiC-A) and 1 mm (SiC-B) were extracted from surrogate nuclear fuels and tested using the two test methods. Mean fracture stresses of 239, 263, and 283 MPa were measured for SiC-A and SiC-B by internal pressurization, and SiC-A by diametrical loading, respectively. In addition, size effects in the fracture stress were investigated using tubular alumina specimens with various sizes. A significant size effect was found in the experimental data and was also predicted by the effective area-based scaling method.

Exposure to 0.1% O sub(2) caused a decrease in the growth rate without affecting viability. Concerted upregulation of the predicted peroxide stress response regulon (PerR) genes was observed in response to the 0.1% O sub(2) exposure. Several of the candidates also showed increases in protein abundance. Among the remaining small number of transcript changes was the upregulation of the predicted transmembrane tetraheme cytochrome c sub(3) complex. Other known oxidative stress response candidates remained unchanged during the low-O sub(2) exposure. To fully understand the results of the 0.1% O sub(2) exposure, transcriptomics and proteomics data were collected for exposure to air using a similar experimental protocol. In contrast to the 0.1% O sub(2) exposure, air exposure was detrimental to both the growth rate and viability and caused dramatic changes at both the transcriptome and proteome levels. Interestingly, the transcripts of the predicted PerR regulon genes were downregulated during air exposure. Our results highlight the differences in the cell-wide responses to low and high O sub(2) levels in D. vulgaris and suggest that while exposure to air is highly detrimental to D. vulgaris, this bacterium can successfully cope with periodic exposure to low O sub(2) levels in its environment.

Under both common garden and warm greenhouse conditions (day/night temperature of 33/25 degree C), the Florida genotype exhibited more growth than the Minnesota genotype. To determine the physiological parameters associated with this response, plants were acclimated to ambient (27/25 degree C) or moderately elevated (33/25 degree C) temperatures for 21 days before measurement of net photosynthesis at temperatures ranging from 25 to 48 degree C. In vivo measurements of gas exchange and chlorophyll a fluorescence of ambient-acclimated plants revealed that, compared with the Minnesota genotype, the Florida genotype maintained a higher photosynthetic rate, higher stomatal conductance, more open PSII reaction centers, a greater PSII quantum yield and a lower quantum requirement for photosystem II ( phi sub(PSII)) per mole of CO sub(2) fixed ( phi sub(CO2)) throughout the measurement temperature range. When both genotypes were acclimated at 33/25 degree C and measured at 33 degree C, analysis of the response of net photosynthesis to calculated intercellular CO sub(2) concentration indicated that the maximal rate of Rubisco carboxylation (V sub(cmax)) decreased more in the Minnesota genotype than in the Florida genotype in response to elevated temperature. Additionally, phi sub(PSII)/ phi sub(CO2) at 33 degree C was markedly higher for Minnesota plants under photorespiratory conditions, but similar to Florida plants under non-photorespiratory conditions. The results indicate that the higher net photosynthetic rate at 33/25 degree C of the Florida genotype compared with the Minnesota genotype could be a result of several mechanisms, including the maintenance of a higher V sub(cmax) and a more efficient quantum requirement of PSII per mole of CO sub(2) fixed, which is likely the result of lower photorespiration.

8111713 AB - Headwater streams are key sites of nutrient and organic matter processing and retention, but little is known about temporal variability in gross primary production (GPP) and ecosystem respiration (ER) rates as a result of the short duration of most metabolism measurements in lotic ecosystems. We examined temporal variability and controls on ecosystem metabolism by measuring daily rates continuously for 2 years in Walker Branch, a first-order deciduous forest stream. Four important scales of temporal variability in ecosystem metabolism rates were identified: (1) seasonal, (2) day-to-day, (3) episodic (storm-related), and (4) inter-annual. Seasonal patterns were largely controlled by the leaf phenology and productivity of the deciduous riparian forest. Walker Branch was strongly net heterotrophic throughout the year with the exception of the open-canopy spring when GPP and ER rates were co-equal. Day-to-day variability in weather conditions influenced light reaching the streambed, resulting in high day-to-day variability in GPP particularly during spring (daily light levels explained 84% of the variance in daily GPP in April). Episodic storms depressed GPP for several days in spring, but increased GPP in autumn by removing leaves shading the streambed. Storms depressed ER initially, but then stimulated ER to 2-3 times pre-storm levels for several days. Walker Branch was strongly net heterotrophic in both years of the study, with annual GPP being similar (488 and 519 g O sub(2) m super(-2) y super(-1) or 183 and 195 g C m super(-2) y super(-1)) but annual ER being higher in 2004 than 2005 (-1,645 vs. -1,292 g O sub(2) m super(-2) y super(-1) or -617 and -485 g C m super(-2) y super(-1)). Inter-annual variability in ecosystem metabolism (assessed by comparing 2004 and 2005 rates with previous measurements) was the result of the storm frequency and timing and the size of the spring macroalgal bloom. Changes in local climate can have substantial impacts on stream ecosystem metabolism rates and ultimately influence the carbon source and sink properties of these important ecosystems.

Nationwide, state-level energy efficiency programs have targeted all sectors of the economy and have employed a wide range of methods to promote energy efficiency. Standard residential and industrial programs typically identify between 20% and 30% energy savings in homes and plants, respectively. Over a 20-year period of time, an average state that aggressively pursues even a limited array of energy efficiency programs can potentially reduce total state energy use by as much as 20%. Well-designed energy efficiency programs can be expected to help overcome numerous barriers to the market penetration of energy efficient technologies and accelerate the market penetration of the technologies. Energy efficiency programs are cost-effective; typical benefit-cost ratios exceed 3:1 and are much higher when non-energy and macroeconomic benefits are included. Indeed, energy efficiency and associated programs and investments can create significant numbers of new jobs and enhance state tax revenues. Several states have incorporated energy efficiency into their economic development programs. It should also be noted that increasing amounts of venture capital are being invested in the energy sector in general and in specific technologies like solar power in particular.

Electrical resistivity, hardness and tensile properties are compared between the as-annealed and aged conditions. Microstructural evaluations were performed by optical, scanning electron microscopy and transmission electron microscopy. An increase in the amount of grain boundary precipitation with increasing aging temperature was found to decrease the electrical resistivity and material strength. Precipitation at the grain boundaries was found to be a mixture of monoclinic and cubic structures, suggesting the development of mixed Hf oxides, carbides and nitrides. Precipitate development caused pronounced embrittlement of the alloy following aging at 1398 K.

Molybdenum alloys with rhenium contents of 41-47.5% (wt%), in particular, have good creep resistance and ductility in both base metal and weldments. However, irradiation-induced changes such as transmutation and radiation-induced segregation could lead to precipitation and, ultimately, radiation-induced embrittlement. The objective of this work is to evaluate the performance of Mo-41Re and Mo-47.5Re after irradiation at space reactor relevant temperatures. Tensile specimens of Mo-41Re and Mo-47.5Re alloys were irradiated to 0.7 displacements per atom (dpa) at 1073, 1223, and 1373 K and 1.4 dpa at 1073 K in the High Flux Isotope Reactor at Oak Ridge National Laboratory. Following irradiation, the specimens were strained to failure at a rate of 1 X 10-3 s-1 in vacuum at the irradiation temperature. In addition, unirradiated specimens and specimens aged for 1100 h at each irradiation temperature were also tested. Fracture mode of the tensile specimens was determined. The tensile tests and fractography showed severe embrittlement and IG failure with increasing temperatures above 1100 K, even at the lowest fluence. This high temperature embrittlement is likely the result of irradiation-induced changes such as transmutation and radiation-induced segregation. These factors could lead to precipitation and, ultimately, radiation-induced embrittlement. The objective of this work is to examine the irradiation-induced degradation for these Mo-Re alloys under neutron irradiation.

The electrical resistivity, hardness and tensile properties of the alloys were measured both before and after aging, along with the alloy microstructures though investigation by optical and electron microscopy techniques. The Mo-41Re alloy retained a single-phase solid solution microstructure following 1100 h aging at all temperatures, exhibiting no signs of precipitation, despite measurable changes in resistivity and hardness in the 1098 K aged material. Annealing Mo-47.5Re for 1 h at 1773 K resulted in a two-phase alpha Mo + sigma structure, with subsequent aging at 1398 K producing a further precipitation of the sigma phase along the grain boundaries. This resulted in increases in resistivity, hardness and tensile strength with a corresponding reduction in ductility. Aging Mo-47.5Re at 1098 and 1248 K led to the development of the xi phase along grain boundaries, resulting in decreased resistivity and increased hardness and tensile strength while showing no loss in ductility relative to the as-annealed material.

Long-term microstructural stability is a requirement of these materials for their use in this type of creep dominated application. Early work on refractory metal alloys has shown aging embrittlement occurring for some niobium and tantalum-base alloys at temperatures near 40% of their melting temperatures in either the base metal or in weldments. Other work has suggested microstructural instabilities during long-term creep testing, leading to decreased creep performance. This paper examines the effect of aging 1100 h at 1098, 1248 and 1398 K on the microstructural and mechanical properties of two niobium (Nb-1Zr and FS-85), tantalum (T-111 and ASTAR-811C) and molybdenum (Mo-41Re and Mo-47.5Re) base alloys. Changes in material properties are examined through mechanical tensile testing coupled with electrical resistivity changes and microstructural examination through optical and electron microscopy analysis.

Comparative genome sequence analysis of three cultured representatives suggests that cellular requirements for nitrogen are largely provided by regenerated ammonium and organic compounds (polyamines, allophanate, and urea), while typical sources of carbon include amino acids, glyoxylate, and aromatic metabolites. An unexpectedly large number of genes are predicted to encode proteins involved in the production, degradation, and efflux of toxins and metabolites. A mechanism likely involved in cell-to-cell DNA or protein transfer was also discovered: vir-related genes encoding a type IV secretion system typical of bacterial pathogens. These suggest a potential for interacting with neighboring cells and impacting the routing of organic matter into the microbial loop. Genes shared among the three roseobacters and also common in nine draft Roseobacter genomes include those for carbon monoxide oxidation, dimethylsulfoniopropionate demethylation, and aromatic compound degradation. Genes shared with other cultured marine bacteria include those for utilizing sodium gradients, transport and metabolism of sulfate, and osmoregulation.

The objectives of this study were to develop methods for producing M-substituted magnetite nanoparticles with a high rate of metal substitution by biological processes and to identify factors affecting the production of nano-crystals. The thermophilic and psychrotolerant iron-reducing bacteria had the ability to form M-substituted magnetite nano-crystals (M sub(y)Fe sub(3) sub(-) sub(y)O sub(4)) from a doped precursor, mixed-M iron oxyhydroxide, (M sub(x)Fe sub(1) sub(-) sub(x)OOH, x approximately equal to 0.5, M is Mn, Zn, Ni, Co and Cr). Within the range of 0.01 approximately equal to x approximately equal to 0.3, using the mixed precursor material enabled the microbial synthesis of more heavily substituted magnetite compared to the previous method, in which the precursor was pure akaganeite and the dopants were present as soluble metal salts. The mixed precursor method was especially advantageous in the case of toxic metals such as Cr and Ni. Also this new method increased the production rate and magnetic properties of the product, while improving crystallinity, size control and scalability.

AN - 70534005; 17229488 AB - This paper presents a reaction-based water quality transport model in subsurface flow systems. Transport of chemical species with a variety of chemical and physical processes is mathematically described by M partial differential equations (PDEs). Decomposition via Gauss-Jordan column reduction of the reaction network transforms M species reactive transport equations into two sets of equations: a set of thermodynamic equilibrium equations representing N(E) equilibrium reactions and a set of reactive transport equations of M-N(E) kinetic-variables involving no equilibrium reactions (a kinetic-variable is a linear combination of species). The elimination of equilibrium reactions from reactive transport equations allows robust and efficient numerical integration. The model solves the PDEs of kinetic-variables rather than individual chemical species, which reduces the number of reactive transport equations and simplifies the reaction terms in the equations. A variety of numerical methods are investigated for solving the coupled transport and reaction equations. Simulation comparisons with exact solutions were performed to verify numerical accuracy and assess the effectiveness of various numerical strategies to deal with different application circumstances. Two validation examples involving simulations of uranium transport in soil columns are presented to evaluate the ability of the model to simulate reactive transport with complex reaction networks involving both kinetic and equilibrium reactions.

The model considers aquatic equilibrium chemistry of uranium and other groundwater constituents, uranium sorption and precipitation, and the microbial reduction of nitrate, sulfate and U(VI). Kinetic sorption/desorption of U(VI) is characterized by mass transfer between stagnant micro-pores and mobile flow zones. The model describes the succession of terminal electron accepting processes and the growth and decay of sulfate-reducing bacteria, concurrent with the enzymatic reduction of aqueous U(VI) species. The effective U(VI) reduction rate and sorption site distributions are determined by fitting the model simulation to an in-situ experiment at Oak Ridge, TN. Results show that (1) the presence of nitrate inhibits U(VI) reduction at the site; (2) the fitted effective rate of in-situ U(VI) reduction is much smaller than the values reported for laboratory experiments; (3) U(VI) sorption/desorption, which affects U(VI) bioavailability at the site, is strongly controlled by kinetics; (4) both pH and bicarbonate concentration significantly influence the sorption/desorption of U(VI), which therefore cannot be characterized by empirical isotherms; and (5) calcium-uranyl-carbonate complexes significantly influence the model performance of U(VI) reduction.

13859099 AB - Fructose-1,6-bisphosphate (F-1,6-P2) is an allosteric activator of two key enzymes of glycolysis: phosphofructokinase and pyruvate kinase. Regulation of glycolysis in a wild-typeSaccharomyces cerevisiae and a recombinantEscherichia coli by a dead-end structural analog of F-1,6-P2 was studied. 2,5-Anhydromannitol (2,5-AM), a structural analog of b-d-fructose, was used. On being taken up by the cells, 2,5-AM was converted into its monophosphate and diphosphate by the enzymes of the glycolytic pathway. The final product, 2,5-anhydromannitol-1,6-bisphosphate, could not be metabolized further and, therefore, accumulated inside the cells. Glucose and fructose were used as substrates. It was found that 2,5-AM at concentrations of 1 mM or less did not have any effect on either substrate consumption or ethanol production. At concentrations of 2,5-AM of 2.5 mM or greater, significant inhibition of both glucose and fructose was observed, with fructose inhibition much more severe. We discuss the possible mechanisms of glycolysis inhibition by 2,5-AM at high concentrations and the regulation of glycolysis by this compound.

Contrary to the claim made by Zhou and Zheng [Zhou, G. T., and Zheng, Y. F. (2003) An experimental study of oxygen isotope fractionation between inorganically precipitated aragonite and water at low temperatures. Geochim. Cosmochim. Acta 67, 387-399], there is excellent agreement between fractionation factors that were experimentally determined by means of slow, inorganic precipitation of calcite from solutions and those obtained largely from theoretical, statistical-mechanical calculations of the reduced partition function ratios. This agreement strongly suggests that calcite was precipitated from a solution very close to isotopic equilibrium. However, recently Zhou and Zheng [Zhou, G. T., and Zheng, Y. F. (2005) Effect of polymorphic transition on oxygen isotope fractionation between aragonite, calcite and water: a low-temperature experimental study. Am. Miner. 90, 1121-1130] presented, without any explanation, conclusions on these major aspects that contradict the previous statements of Zhou and Zheng (2003). The apparent discrepancy in calcite-water oxygen isotope fractionation between experimental and theoretical studies discussed by Zhou and Zheng (2003) originates from the "mineral-water interaction" term in the modified increment method, which was developed by one of the authors (Y. F. Zheng). We call for evidence for the theoretical nature of the modified increment method, which has never been presented in any of Zheng's papers. Without such evidence, great caution must be exercised in using fractionation factors derived from the modified increment method.

We estimate the largest category of economic losses from electricity outages-business interruption-in the context of a total blackout of electricity in Los Angeles. We advance the state of the art in the estimation of the two factors that strongly influence the losses: indirect effects and resilience. The results indicate that indirect effects in the context of general equilibrium analysis are moderate in size. The stronger factor, and one that pushes in the opposite direction, is resilience. Our analysis indicates that electricity customers have the ability to mute the potential shock to their business operations by as much as 86%. Moreover, market resilience lowers the losses, in part through the dampening of general equilibrium effects.

The present study applied integrative star-plot analysis to evaluate effects of stressors over several levels of biological organization ranging from the sub-organism to the community level at study sites subjected to different levels of contaminant stress. An aquatic ecosystem health index (AEHI), based on the sum of all the star-plot areas over these levels of biological organization, was developed to reflect an integrative and holistic assessment of stressors on ecosystem health. Star-plot areas ranged from 1.96 at a reference site to 0.79-1.08 at sites located at increasing distances downstream from a pulp mill discharge. The values of the AEHI were positively correlated with the index of biotic integrity (IBI) scores (Pearson's r=0.824). The AEHI can be used to evaluate the overall health status of aquatic systems, to identify those levels of biological organization that have the greatest response to environmental stressors, and to help identify possible causes of observed effects. Results from this study suggest that the AEHI approach can avoid false-negative responses that can occur from assessing effects at only one level of biological organization.

We investigated the pulmonary toxicity of single-walled carbon nanohorns (SWCNHs), a relatively new carbon-based nanomaterial that is structurally similar to SWCNTs. Mice were exposed to 30 µg of surfactant-suspended SWCNHs or an equal volume of vehicle control by pharyngeal aspiration and sacrificed 24 hours or 7 days post-exposure. Total and differential cell counts and cytokine analysis of bronchoalveolar lavage fluid demonstrated a mild inflammatory response which was mitigated by day 7 post-exposure. Whole lung microarray analysis demonstrated that SWCNH-exposure did not lead to robust changes in gene expression. Finally, histological analysis showed no evidence of granuloma formation or fibrosis following SWCNH aspiration. These combined results suggest that SWCNH is a relatively innocuous nanomaterial when delivered to mice in vivo using aspiration as a delivery mechanism.

We examined the effects of tree susceptibility and resistance to herbivory on litter microarthropod and soil microbial communities to test the general hypothesis that herbivore driven changes in litter inputs and soil microclimate will feedback to the microbial community. Our study population consisted of individual pinon pine trees that were either susceptible or resistant to the stem-boring moth (Dioryctria albovittella) and susceptible pinon pine trees from which the moth herbivores have been manually removed since 1982. Moth herbivory increased pinon litter nitrogen concentrations (16%) and decreased canopy precipitation interception (28%), both potentially significant factors influencing litter and soil microbial communities. Our research resulted in three major findings: (1) In spite of an apparent increase in litter quality, herbivory did not change litter microarthropod abundance or species richness. (2) However, susceptibility to herbivores strongly influenced bulk soil microbial communities (i.e., 52% greater abundance beneath herbivore-resistant and herbivore-removal trees than susceptible trees) and alkaline phosphatase activity (i.e., 412% increase beneath susceptible trees relative to other groups). (3) Season had a strong influence on microbial communities (i.e., microbial biomass and alkaline phosphatase activity increased after the summer rains), and their response to herbivore inputs, in this semi-arid ecosystem. Thus, during the dry season plant resistance and susceptibility to a common insect herbivore had little or no observable effects on the belowground organisms and processes we studied, but after the rains, some pronounced effects emerged.

Pressure-driven atomization/nebulization, ultrasonic generation, and electrospraying are common aerosol generation techniques that are currently used. Electrospray produced monodispersed isolated particles, when the original material was reasonably monodisperse, which may be most suited for use in experiments requiring single-size aerosol population. The technique however requires the use of a conductive solution that may not be suitable in biological experiments. Also, in the generation of single walled carbon nanohorns (SWNHs), we found that electrospray produced an anonymous peak that was not consistent with currently known SWNH nanostructures. This adds to an uncertainty about its utility in nanotoxicological experiments. Though producing controllable larger cluster sizes, ultrasonic generation might be a relatively straightforward process for reproducibly generating nanoparticle aggregates for nanotoxicological research. Note that the ultrasonic generation is not to be confused with sonication that is commonly used to homogenize a colloidal suspension. The aerosol population produced by a pressure-driven atomizer was very broad, suitable for experiments requiring a simple, easy means to deliver/disperse colloidal suspensions where size distribution is not a major concern. Advantages and disadvantages of each method are presented in relation to future toxicology experiments.

Looking a half-century or more into the future, one of the key issues for the world's cities is coping with rapid growth, especially when cities are in locations vulnerable to environmental stress, and a very salient example of an emerging environmental stress is climate change. How might a city--especially in the developing world--be vulnerable to impacts of climate change, and what kinds of responses make sense for them now in a larger context of sustainable development?

Several attempts to find core tau p scaling based on the same dataset have reached contradictory conclusions: core particle diffusivity inversely proportional to density, scaling proportional to density, and scaling independent of collisionality (density independence). The analyses have also varied the assumed boundary conditions. In all three cases, ELM-averaged transport was analyzed. To see what can be learned about resolution of such differences through possible systematic SOL effects on particle transport scaling, using the available edge/SOL data for these core particle transport experiments, we analyze representative cases from the JET trace T experimental database. The pulses considered cover a range in average core electron density, with approximately constant tritium puffing rates. The study is motivated by the realization that, although these experiments were not designed for such a purpose, similar future 'trace T' experiments could better characterize the SOL, and thus its influence of on particle transport in the edge/pedestal region (0.8 < rho < 1) since important elements of the tritium pathway are measured: the external T2 gas puff rate , and, from the neutron analysis, the influx to the plasma core region at rho = 0.8 and the efflux from the core . Systematic effects on edge/pedestal particle transport scaling in puffing experiments are found to depend on the status of saturation in the near-inlet region, on the details of ELM-induced particle expulsion from both core and SOL, and on the degree of near-wall T enrichment.

To be able to compare with observations in this complex environment, a model for carbon generation and transport has been created to include contributions from the important, but non-ideal, processes of carbon generation from material in intra-tile gaps and from poorly adherent re-deposited layers. Consistency simulations have been carried out to assess the degree to which the spot observations represent local emission, due to possibly long mean free paths of high-energy emitted particles, or from impurities transported into the spectroscopic field of view from other areas. Model results are compared with the experimental trends in the ratio of CII and D alpha emission with power and edge parameters. In the course of the analysis a potentially important vector has been found for transport of re-deposited material to more remote locations and its significance discussed.

These experiments were conducted with 0.6 Ip 0.9 MA, 1 < PNBI < 6 MW, on-axis toroidal field Bt = 0.45 T, in a lower-single null discharge shape with elongation mu 2.0, triangularity delta 0.45, and the ion grad-B drift toward the X-point. As PNBI was raised from 1 MW to 6 MW, the outer divertor peak heat flux was observed to increase up to 6 MW/m2. A break in the slope of peak heat flux vs. power was observed at heating power 3 MW, which we interpret as the transition of the divertor toward the high recycling regime and well away from the detachment threshold. The peak heat flux was also observed to increase strongly with Ip.

The National Academy of Sciences has called for the careful application of systems analysis tools to structure the complex assessment required. Others, raising cautionary notes, question whether a consistent and plausible transition to hydrogen light-duty vehicles can be identified and whether that transition would, on balance, be environmentally preferred. Modeling the market transition to hydrogen-powered vehicles is an inherently complex process encompassing hydrogen production, delivery and retailing, vehicle manufacturing, and vehicle choice and use. This paper describes the integration of key technological and market factors in a dynamic transition model, Hy Trans. The usefulness of Hy Trans and its predictions depends on three key factors: the validity of the economic theories that underpin the model, the authenticity with which the key processes are represented, and the accuracy of specific parameter values used in the process representations. The paper summarizes the theoretical basis of Hy Trans and, with sensitivity analysis, highlights the implications of key parameter specifications.

Faster than expected transport of contaminants in the vadose zone is typically attributed to either physical hydrologic processes such as development of preferential flow pathways, or to geochemical processes such as the formation of stable, anionic complexes with organic chelates, e.g., ethylenediaminetetraacetic acid (EDTA). The goal of this paper is to determine whether hydrological processes in the Hanford sediments can influence the geochemistry of the system and hence control transport of Sr (super 2+) and SrEDTA (super 2-) . The study used batch isotherms, saturated packed column experiments, and an unsaturated transport experiment in an undisturbed core. Isotherms and repacked column experiments suggested that the SrEDTA (super 2-) complex was unstable in the presence of Hanford sediments, resulting in dissociation and transport of Sr (super 2+) as a divalent cation. A decrease in sorption with increasing solid:solution ratio for Sr (super 2+) and SrEDTA (super 2-) suggested mineral dissolution resulted in competition for sorption sites and the formation of stable aqueous complexes. This was confirmed by detection of MgEDTA (super 2-) , MnEDTA (super 2-) , PbEDTA (super 2-) , and unidentified Sr and Ca complexes. Displacement of Sr (super 2+) through a partially-saturated undisturbed core resulted in less retardation and more irreversible sorption than was observed in the saturated repacked columns, and model results suggested a significant reservoir (49%) of immobile water was present during transport through the heterogeneous layered sediments. The undisturbed core was subsequently disassembled along distinct bedding planes and subjected to sequential extractions. Strontium was unequally distributed between carbonates (49%), ion exchange sites (37%), and the oxide (14%) fraction. An inverse relationship between mass wetness and Sr suggested that sandy sediments of low water content constituted the immobile flow regime. Our results suggested that the sequestration of Sr (super 2+) in partially-saturated, heterogeneous sediments was most likely due to the formation of immobile water in drier regions having low hydraulic conductivities.

AN - 70463158; 17385904 AB - Proteome alterations in the metal-reducing bacterium Shewanella oneidensis MR-1 in response to different acute dose challenges (0.3, 0.5, or 1 mM) of the toxic metal chromate [Cr(VI)] were characterized with multidimensional HPLC-MS/MS. Proteome measurements were performed and compared on both quadrupole ion traps as well as linear trapping quadrupole mass spectrometers. We have found that the implementation of multidimensional liquid chromatography on-line with the rapid scanning, high throughput linear trapping quadrupole platform resulted in a dramatic increase in the number of measured peptides and, thus, the number of identified proteins. A total of 2406 functionally diverse, nonredundant proteins were identified in this study, representing a relatively deep proteome coverage for this organism. The core molecular response to chromate challenge under all three concentrations consisted predominantly of proteins with annotated functions in transport and binding (e.g., components of the TonB1 iron transport system, TonB-dependent receptors, and sulfate transporters) as well as a functionally undefined DNA-binding response regulator (SO2426) that might play a role in mediating metal stress responses. In addition, proteins annotated as a cytochrome c, a putative azoreductase, and various proteins involved in general stress protection were up-regulated at the higher Cr(VI) doses (0.5 and 1 mM) only. Proteins down-regulated in response to metal treatment were distributed across diverse functional categories, with energy metabolism proteins dominating. The results presented in this work demonstrate the dynamic dosage response of S. oneidensis to sub-toxic levels of chromate.

We find the aggregate impacts of a $25/ton carbon tax on the SRB economy are likely to be negative but modest -- an approximately one-third of 1% reduction in Gross Regional Product (GRP) in the short-run and double that amount in the long-run. However, unlike many previous studies, we find that the carbon tax is mildly progressive as measured by income bracket changes, per capita equivalent variation, and Gini coefficient changes based on expenditure patterns. The dominant factors affecting the distributional impacts are the pattern of output, income and consumption impacts that affect lower income groups relatively less than higher income ones, an increase in transfer payments favoring lower income groups, and decreased corporate profits absorbed primarily by higher income groups.

Thus, the presence of magnetite and/or hematite in rocks has been linked to a specific oxidation environment. However, the availability of reductants or oxidants in many geologic and industrial environments appears to have been too low to account for the transformations of iron oxides through redox reactions. Here, we report the results of hydrothermal experiments in mildly acidic and H (sub 2) -rich aqueous solutions at 150 degrees C, which demonstrate that transformations of magnetite to hematite, and hematite to magnetite, occur rapidly without involving molecular O (sub 2) or H (sub 2) : Fe (sub 3) O (sub 4) (Mt)+2H (sub (aq)) (super +) Fe (sub 2) O (sub 3) (Hm)+Fe (sub (aq)) (super 2+) +H (sub 2) O. The transformation products are chemically and structurally homogeneous, and typically occur as euhedral single crystals much larger than the precursor minerals. This suggests that, in addition to the expected release of aqueous ferrous species to solution, the transformations involve release of aqueous ferric species from the precursor oxides to the solution, which reprecipitate without being reduced by H (sub 2) . These redox-independent transformations may have been responsible for the formation of some iron oxides in natural systems, such as high-grade hematite ores that developed from Banded Iron Formations (BIFs), hematite-rich deposits formed on Mars, corrosion products in power plants and other industrial systems.

Parallel visualization systems are becoming more common in scientific computing due to the decreasing hardware costs and availability of the open source software to support such architecture. High-resolution displays allow scientists to visualize very large data sets with minimal loss of details. Such systems have a big promise especially in the field of GIS because users can naturally combine several geographic scales on a single display. This paper discusses architecture, implementation, and operation of pd-GRASS-a GRASS GIS extension for high-performance parallel visualization on tiled displays. pd-GRASS is specifically well suited for very large geographic data sets, such as light detecting and ranging data or high-resolution nation-wide geographic databases. This paper also briefly touches on computational efficiency, performance, and potential applications for such systems.

However, little information is gained for the members of the community present at low frequencies, especially those representing yet-uncultured taxa, which include the bulk of the diversity present in most environments. Here we used phylogenetically directed cell separation by fluorescence in situ hybridization and flow cytometry, followed by amplification and sequencing of a fraction of the genomic DNA of several bacterial cells that belong to the TM7 phylum. Partial genomic assembly allowed, for the first time, a look into the evolution and potential metabolism of a soil representative from this group of organisms for which there are no species in stable laboratory cultures. Genomic reconstruction from targeted cells of uncultured organisms isolated directly from the environment represents a powerful approach to access any specific members of a community and an alternative way to assess the community's metabolic potential.

The framework is most pertinent to the spatial scale of residential treatment systems located adjacent to small ponds, streams, or lagoons and some parts of shallow estuaries. Freshwater and estuarine ecosystems are distinguished based on differences in nutrient dynamics. Phosphorus exposure is the major determinant of phytoplankton production in most North American lakes. Nitrate can be directly toxic to aquatic biota such as amphibians. In shallow estuaries or lagoons, nitrogen is the primary stressor, which can be directly toxic to vegetation or can interact with biota to produce secondary stressors (limited light penetration, oxygen limitation, reduction in habitat, or reduction in forage vegetation or prey). Algal production, macrophyte production, fish community abundance and production, benthic community abundance and production, and amphibian community abundance and production are examples of risk assessment endpoint properties. Models and measurement methods for the characterization of exposure and effects are discussed, as well as sources and quantification of uncertainty. Example weight-of-evidence tables are presented for failure scenarios involving traditional and emerging onsite wastewater system technologies.

The Charpy transition temperature shift data contained in the Power Reactor Embrittlement Database is used in this study. Six parameters-Cu, Ni, P, neutron fluence, irradiation time, and irradiation temperature - are used in the embrittlement prediction models. The results indicate that this new embrittlement predictor achieved reductions of about 49.5% and 52% in the uncertainties for plate and weld data, respectively, for pressurized water reactor and boiling water reactor data, compared with the Nuclear Regulatory Commission Regulatory Guide 1.99, Rev. 2. The implications of dose-rate effect and irradiation temperature effects for the development of radiation embrittlement models are also discussed.

13858574 AB - Clostridium thermocellum is an anaerobic, thermophilic bacterium that can directly convert cellulosic substrates into ethanol. Microarray technology is a powerful tool to gain insights into cellular processes by examining gene expression under various physiological states. Oligonucleotide microarray probes were designed for 96.7% of the 3163 C. thermocellum ATCC 27405 candidate protein-encoding genes and then a partial-genome microarray containing 70 C. thermocellum specific probes was constructed and evaluated. We detected a signal-to-noise ratio of three with as little as 1.0 ng of genomic DNA and only low signals from negative control probes (nonclostridial DNA), indicating the probes were sensitive and specific. In order to further test the specificity of the array we amplified and hybridized 10 C. thermocellum polymerase chain reaction products that represented different genes and found gene specific hybridization in each case. We also constructed a whole-genome microarray and prepared total cellular RNA from the same point in early-logarithmic growth phase from two technical replicates during cellobiose fermentation. The reliability of the microarray data was assessed by cohybridization of labeled complementary DNA from the cellobiose fermentation samples and the pattern of hybridization revealed a linear correlation. These results taken together suggest that our oligonucleotide probe set can be used for sensitive and specific C. thermocellum transcriptomic studies in the future.

In this work, we report on tracer tests conducted in a well system comprising two injection and two extraction wells designed for an in situ bioremediation of uranium at Oak Ridge, TN, about 2 years after the start of operation. The domain of the flow field can be divided into an inner cell, an outer cell, and transition zones. To characterize advective-dispersive transport, two tracer tests were performed with the injection of bromide solution. The system was operated as during groundwater remediation, and the tracer was partially recirculated. Breakthrough curves (BTCs) were measured in the extraction wells and the multi-level sampling (MLS) ports. The methods of transfer function and temporal moments were implemented to analyze the BTCs. By jointly evaluating the temporal moments of the BTCs in the extraction wells, we can conveniently estimate the recirculating flow fractions in different zones. This approach does not require the detailed characterization of the flow field. The parameters of transfer functions fitted at the MLS wells indicate the flow field may have changed over the tracer test period. This observation indicates that bioremediation influences the flow field even when the well pumping rates are kept constant, which suggests that aquifer characterization may need to be repeated during bioremediation. The methods of transfer functions and temporal moments with tracer tests are flexible, economical, and well-suited to evaluate the performance of the system during long periods of remediation.

AN - 70487801; 17494393 AB - This study examines secondary production and periphyton-invertebrate food web energetics at two sites in an industrially contaminated, nutrient-enriched stream. Secondary production data and data from the literature were used to calculate potential amounts of mercury transferred from periphyton to chironomid larvae and into terrestrial food webs with emerging adults. The nutritional quality of periphyton was characterized using energy content, chlorophyll a, protein, ash-free dry mass (AFDM), and percentage of organic matter. Chironomid larvae (Orthocladiinae: Cricotopus spp.) comprised 96% of all macroinvertebrates collected from stones at the two sites. Cricotopus production was extremely high: production was 59.5 g AFDM x m(-2) x yr(-1) at the site upstream of a 1-ha settling basin and 32.4 g AFDM x m(-2) x yr(-1) at the site below the basin. Apparent differences in annual secondary production were associated with reduced organic content (i.e., nutritional quality) of the periphyton matrix under different loading of total suspended solids. The periphyton matrix at both sites was contaminated with inorganic (Hg(II)) and methyl (MeHg) mercury. The amount of Hg(II) potentially ingested by Cricotopus was calculated to be 49 mg Hg(II) x m(-1) x yr(-1) at the upstream site and 19 mg Hg(II)x m(-2) x yr(-1) at the downstream site. Mercury ingestion by Cricotopus at the downstream site was calculated to be 2% of the estimated annual deposition of particulate-bound Hg(II) to the stream bed. Emergence of adult Cricotopus was calculated to remove 563 microg Hg(II)x m(-2) x yr(-1) from the stream at the upstream site and 117 microg Hg(II) x m(-2) x yr(-1) at the downstream site, which amounted to 4.1 g Hg(II)/yr for the 2.1-km reach of stream included in this study. The ratio of metal export in emergence production to surface area for the study stream was 10 to 10(3) times higher than ratios calculated for lakes using data from the literature. This study is the first well-documented example of extremely high aquatic insect production in an industrially contaminated, nutrient-enriched stream, and it highlights the application of production measurements to examine the role of aquatic insect production in the trophic transfer of energy and persistent contaminants in aquatic food webs and into terrestrial food webs.

A robust technique for sample storage and transfer from experimental apparatus to stable isotope mass spectrometer provides a methodology for integration of both carbon and hydrogen isotope characterization of reactants and products generated during abiogenic synthesis experiments. Experiments were performed with and without pretreatment of magnetite to remove background carbon associated with the mineral catalyst. Prior to experiments, the abundance and carbon isotope composition of all carbon-bearing components were determined. Time-series samples of the fluid from all experiments indicated significant concentrations of dissolved CO and C (sub 1) -C (sub 3) hydrocarbons and relatively large changes in dissolved CO (sub 2) and H (sub 2) concentrations, consistent with formation of additional hydrocarbon components beyond C (sub 3) . The existence of relatively high dissolved alkanes in the experiment involving non-pretreated magnetite in particular, suggests a complex catalytic process, likely involving reinforcing effects of mineral-derived carbon with newly synthesized hydrocarbons at the magnetite surface. Similar reactions may be important mechanisms for carbon reduction in chemically complex natural hydrothermal systems. In spite of evidence supporting abiotic hydrocarbon formation in all experiments, an "isotopic reversal" trend was not observed for (super 13) C values of dissolved alkanes with increasing carbon number. This may relate to the specific mechanism of carbon reduction and hydrocarbon chain growth under hydrothermal conditions at elevated temperatures and pressures. Over time, significant (super 13) C depletion in CH (sub 4) suggests either depolymerization reactions occurring in addition to synthesis, or reactions between the C (sub 1) -C (sub 3) hydrocarbons and carbon species absorbed on mineral surfaces and in solution.

Two samples of Reed Dolomite from southwestern Nevada were cut into cylinders approximately 4X6 mm in size. The cores were sealed in gold capsules with isotopically enriched water (H (sub 2) (super 18) O or HD (super 18) O (sub 0.5) (super 16) O (sub 0.5) ). The samples were heated in a cold-seal hydrothermal apparatus to 650-750 degrees C at 100 MPa for durations ranging from 2-59 days. The cores were then sectioned and examined by EPMA, XRD, and SIMS techniques. All experiments showed some amount of reaction regardless of duration or temperature. Reaction products occurred mainly along grain boundaries, fractures within grains, and along sample edges. Ion images and isotope-ratio analysis indicated that reaction products exchanged with infiltrating fluids. Reaction rates were calculated from measured extents of reaction, which were determined from automated EPMA modes. At 700 degrees C, we measured reaction rates ranging from 3.8X10 (super -14) to 2.3X10 (super -12) mol/mm (super 2) .s. The extent of reaction is proportional to the square root of time, suggesting a diffusion-controlled process. A shrinking-core model for the dolomite breakdown reaction fits the grain-size data, suggesting that diffusion of H (sub 2) O and CO (sub 2) through the mantle of reaction products controlled the rate. Apparent activation energies for that diffusion are approximately 283+ or -32 kJ/mol for coarse-grained samples and approximately 333+ or -36 kJ/mol for fine-grained samples. Initial reaction occurred relatively fast near the surface of dolomite grains, but continued diffusion through the reaction products ultimately controlled the rate of dolomite breakdown.

This offshoring phenomenon is studied from a political, economic, technological and strategic perspective. Next, an analytical model is developed for achieving strategic advantage from offshoring based on global partnerships. The model studies the impact of offshoring with respect to the complexity and strategic nature of the tasks and presents a decision strategy for obtaining value through offshoring of increasingly complex tasks. The result is an integrated '24-hour knowledge factory' that is based on a sustainable global model rather than a short term fiscal model. This 24-hour paradigm embodies the shift-style workforce that evolved for the manufacturing sector during the Industrial Revolution and relies on a set of critical success factors in the current environment. A case example is provided from IBM to illustrate these underlying critical success factors.

The Energy Policy Act of 2005 encouraged the development of these sources of renewable energy in the United States, and there is growing interest in deploying them globally. The technologies that would extract electricity from free-flowing streams, estuaries, and oceans have not been widely tested. Consequently, the U.S. Department of Energy convened a workshop to (1) identify the varieties of hydrokinetic energy and wave energy conversion devices and their stages of development, (2) identify where these technologies can best operate, (3) identify the potential environmental issues associated with these technologies and possible mitigation measures, and (4) develop a list of research needs and/or practical solutions to address unresolved environmental issues. We review the results of that workshop, focusing on potential effects on freshwater, estuarine, and marine ecosystems, and we describe recent national and international developments.Original Abstract: Una nueva generacion de tecnologia hidrocinetica y la transformacion de la energia derivada de las, olas naturales permiten derivar electricidad a partir del movimiento del agua sin alterar su cauce natural. En los Estados Unidos de America la Ley de Politica de Energia aprobada en el 2005 promueve el desarrollo de este tipo de tecnologia de production de energia renovable y en todo el mundo hay un creciente interes por impulsarla. Este tipo de tecnologia que podria extraer energia de las corrientes de los rios, estuarios y oceanos no ha sido evaluada. Consecuentemente, el Departamento de Energia de los Estados Unidos de America organizo un taller de trabajo para (1) identificar los dife-rentes equipos que se utilizan para la produccion de energia extraida del movimiento del agua y su grado de desarrollo, (2) identificar los mejores lugares para aplicar dicha tecnologia, (3) identificar los impactos potenciales y medidas de mitigacion asociadas a su uso, y (4) enlistar las necesidades de investigacion y soluciones practicas aplicables a topicos ambientales. Nosotros revisamos los resultados del taller de trabajo, enfocandonos en los impactos potenciales sobre los ecosistemas fluviales, estuarinos y marinos y describimos los avances de investigacion nacional e internacional.

The first process was a lipase-mediated chemo-enzymatic reaction, whereas the second one was a one-step enzymatic process using chloroperoxidase. The PO produced through the chemo-enzymatic process is a racemic product, whereas the latter process (based on chloroperoxidase) produces an enantio-pure product. The former process thus falls under the category of high-volume commodity chemical (PO); whereas the latter is a low-volume, high-value product (SO).

Four principal fracture mechanisms were considered: cleavage fracture, low temperature ductile fracture, transgranular creep fracture, and intergranular creep fracture. The methodology was applied to calculate fracture mechanism maps for several selected reactor materials, CuCrZr, 316 type stainless steel, F82H ferritic-martensitic steel, V4Cr4Ti and Mo. The calculated fracture maps are in good agreement with empirical maps obtained from experimental observations. The fracture mechanism maps of unirradiated metals and alloys were modified to include radiation hardening effects on cleavage fracture and high temperature helium embrittlement. Future refinement of fracture mechanism maps is discussed.

After irradiation to significant doses, these alloys show radiation-induced strengthening and often experience prompt necking at yield followed by large necking deformation. In the present work, the critical true stresses for deformation and fracture events, such as yield stress (YS), plastic instability stress (PIS), and true fracture stress (FS), were obtained from uniaxial tensile tests or calculated using a linear strain-hardening model for necking deformation. At low dose levels where no significant embrittlement was detected, the true fracture stress was nearly independent of dose. The plastic instability stress was also independent of dose before the critical dose-to-prompt-necking at yield was reached. A few bcc alloys such as ferritic martensitic steels experienced significant embrittlement at doses above 1 dpa; and the true fracture stress decreased with dose. The materials fractured before yield at or above 10 dpa. JF - Journal of Nuclear Materials AU - Byun, T S AD - Oak Ridge National Laboratory, P.O.

High number densities, 5 and 7 X 1023 m-3, respectively, of 2-nm-diameter copper-, nickel-, manganese- and silicon-enriched precipitates were observed after neutron irradiation. These copper-enriched precipitates were observed both in the matrix of the steel and also preferentially located along the dislocations. No appreciable differences were observed in the sizes or the compositions of the precipitates in the matrix and on the dislocations. The average interparticle distance along the dislocations was 11 - 3 nm. Phosphorus segregation was also evident along the dislocations in both welds. No other nanoscale intragranular phases were observed in these neutron irradiated welds.

Currently, the database contains damage energy, displacement, helium, and hydrogen cross sections for 23 elemental targets irradiated by proton and neutron projectiles up to 3.2 GeV. In this paper, the focus is on proton-induced helium cross sections, but it is shown that for high energies (above about 500 MeV) proton- and neutron-induced helium cross sections are almost equal. The cross section calculations were run on the Cascade-Exciton Model code (no options) and also on the Bertini code with three nuclear level-density models and multistage pre-equilibrium model on and off. Calculation and experimental results are compared. For various targets, we tried to determine which code and options give best agreement with experiment. In some cases, such determinations are uncertain, partly because of limited and conflicting experimental information and partly perhaps because of the need for modifications in the codes.

A new method of solving the two-dimensional master equation (ME) describing He-vacancy cluster evolution has been applied to calculate helium bubble evolution in a stainless steel irradiated with alpha particles near room temperature and annealed in the temperature range of 600-900 °C. For the first time, the evolution of the helium bubble size distribution function was precisely calculated in 2-D phase space and good agreement with experimental results was obtained. The results indicate that Brownian motion of bubbles via surface vacancy diffusion provides a reasonable explanation for bubble evolution during annealing, most bubbles are found to be near the equilibrium state during the evolution at temperatures of 700 °C and higher, lack of vacancies at temperatures lower than 700 °C prevents bubble growth, and use of a non-ideal He equation of state (EOS) increases the bubble density and size relative to the case when the ideal EOS is used.

Here we report that the Siberian permafrost isolates Exiguobacterium sibiricum 255-15, E. sibiricum 7-3, Exiguobacterium undae 190-11 and E. sp. 5138, as well as Exiguobacterium antarcticum DSM 14480, isolated from a microbial mat sample of Lake Fryxell (McMurdo Dry Valleys, Antarctica), were able to grow at temperatures ranging from -6 to 40 super(o)C. In comparison to cells grown at 24 super(o)C, the cold-grown cells of these strains tended to be longer and wider. We also investigated the effect of growth conditions (broth or surface growth, and temperature) on cryotolerance of the Exiguobacterium strains. Bacteria grown in broth at 4 super(o)C showed markedly greater survival following freeze-thawing treatments (20 repeated cycles) than bacteria grown in broth at 24 super(o)C. Surprisingly, significant protection to repeated freeze-thawing was also observed when bacteria were grown on agar at either 4 or 24 super(o)C.

Information system projects usually have numerous uncertainties and several conditions of risk that make their economic evaluation a challenging task. Each year, several information system projects are cancelled before completion as a result of budget overruns at a cost of several billions of dollars to industry. Although engineering economic analysis offers tools and techniques for evaluating risky projects, the tools are not enough to place information system projects on a safe budget/selection track. There is a need for an integrative economic analysis model that will account for the uncertainties in estimating project costs, benefits, and useful lives of uncertain and risky projects. In this study, we propose an approximate method of computing project present value using the concept of fuzzy modeling with special reference to information system projects. This proposed model has the potential of enhancing the project selection process by capturing a better economic picture of the project alternatives. The proposed methodology can also be used for other real-life projects with high degree of uncertainty and risk.

Saprolite is a collective term referring to partially-weathered bedrock. It exists extensively in the subsurface. Because the parent bedding structures are maintained during the weathering process, saprolite soils are characterized by intensive fractures and secondary deposits of minerals such as Al-, Fe- and Mn-oxides on the fracture surfaces. Movement of reactive species through the soils may be influenced by diffusion into the rock matrix, a physical mass transfer (PMT) process, and interfacial chemical reactions, a chemical mass transfer (CMT) process. The PMT and CMT processes are phenomenologically similar but mechanistically different. In this research, previous laboratory observations from a Br and Co(II)EDTA tracer injection into an undisturbed saprolite soil column were used. Mechanistic reactive transport models were formulated to quantify the PMT and CMT processes. The PMT process was independently characterized by using the non-reactive tracer Br. Model parameters thus obtained were subsequently used as constraints to quantify the CMT processes involving Co(II)EDTA and its oxidation product Co(III)EDTA. Our calculations indicated that the PMT rates of the less reactive Co(III)EDTA were comparable with their theoretical CMT rates. In contrast, for the more reactive species Co(II)EDTA, CMT rates are higher than PMT rates. Evaluations of alternative CMT process models further confirmed one of our hypotheses on the basis of previous experimental understandings. The hypothesis suggested that competition from Fe-oxide for Co(II)EDTA may account for the majority of the decrease of Co(III)EDTA effluent concentrations that resulted in the separation of total Co and Co(III)EDTA breakthrough curves. Because Co(III)EDTA is more mobile than Co(II)EDTA in the subsurface, the results of this research suggest independent quantifications of CoEDTA PMT and CMT processes if laboratory results are to be interpreted correctly and scaled up for field and predictive uses.

AN - 70305810; 17295465 AB - A computational approach has been developed for performing efficient and reasonably accurate toxicity evaluation and prediction. The approach is based on computational neural networks linked to modern computational chemistry and wavelet methods. In this paper, we present details of this approach and results demonstrating its accuracy and flexibility for predicting diverse biological endpoints including metabolic processes, mode of action, and hepato- and neurotoxicity. The approach also can be used for automatic processing of microarray data to predict modes of action.

AN - 68994263; 17174358 AB - Mutagenic, reproductive, and toxicity effects of two closely related chemicals, ethylnitrosourea (ENU) and methylnitrosourea (MNU), were compared at equimolar and near-equimolar doses in the mouse specific-locus test in a screen of all stages of spermatogenesis and spermiogenesis. In stem-cell spermatogonia (SG), ENU is more than an order of magnitude more mutagenic than MNU. During post-SG stages, both chemicals exhibit high peaks in mutation yield when differentiating spermatogonia (DG) and preleptotene spermatocytes are exposed. The mutation frequency induced by 75mgMNU/kg during this peak interval is, to date, the highest induced by any single-exposure mutagenic treatment - chemical or radiation - that allows survival of the exposed animal and its germ cells, producing an estimated 10 new mutations per genome. There is thus a vast difference between stem cell and differentiating spermatogonia in their sensitivity to MNU, but little difference between these stages in their sensitivity to ENU. During stages following meiotic metaphase, the highest mutation yield is obtained from exposed spermatids, but for both chemicals, that yield is less than one-quarter that obtained from the peak interval. Large-lesion (LL) mutations were induced only in spermatids. Although only a few of the remaining mutations were analyzed molecularly, there is considerable evidence from recent molecular characterizations of the marker genes and their flanking chromosomal regions that most, if not all, mutations induced during the peak-sensitive period did not involve lesions outside the marked loci. Both ENU and MNU treatments of post-SG stages yielded significant numbers of mutants that were recovered as mosaics, with the proportion being higher for ENU than for MNU. Comparing the chemicals for the endpoints studied and additional ones (e.g., chromosome aberrations, toxicity to germ cells and to animals, teratogenicity) revealed that while MNU is generally more effective, the opposite is true when the target cells are SG.

In these examples, the earliest quartz cements have the highest delta (super 18) O values (up to 33ppm; mean=26.0ppm, V-SMOW) indicative of low temperature precipitation at depths of 0 to 1.1 km. Some paragenetically early cement phases, however, have lighter isotopic values that suggest either precipitation from isotopically depleted water or precipitation at higher temperatures. Subsequent generations of quartz cements have progressively lower delta (super 18) O values (mean=+16.1+ or -3%%) consistent with precipitation at higher temperatures. These data combined with petrographic observations indicate quartz cementation began in near-surface vadose and phreatic zones; the next stage of cementation is characterized by syntaxial burial cement overgrowths. Regionally and stratigraphically, well-sorted sandstone facies that were initially aquifers preferentially experienced early quartz cementation, which resulted in cement-bridged pore throats at relatively shallow depths of 0-2 km and very early in their burial history transforming these units into diagenetic aquitards. As a result, these units did not experience mineralization. Compositionally and texturally immature braided fluvial facies did not experience early addition of quartz cement, but are instead marked by minor syntaxial overgrowth cement that make up <5% of the intergranular volume, formed at depths of 3-5 km, and were variably replaced by illite and chlorite during burial. These lithologies were still open to fluid movement at critical times in the basin when U and Pb-Zn-Ag deposits formed, and as a result experienced mineralization. Because of these relationships, the hydraulic properties of these Proterozoic sandstones would be difficult to predict based simply on their original texture.

Strain PM1 also degrades aromatic (benzene, toluene, and xylene) and straight-chain (C sub(5) to C sub(12)) hydrocarbons present in petroleum products. Whole-genome analysis of PM1 revealed an similar to 4-Mb circular chromosome and an similar to 600-kb megaplasmid, containing 3,831 and 646 genes, respectively. Aromatic hydrocarbon and alkane degradation, metal resistance, and methylotrophy are encoded on the chromosome. The megaplasmid contains an unusual t-RNA island, numerous insertion sequences, and large repeated elements, including a 40-kb region also present on the chromosome and a 29-kb tandem repeat encoding phosphonate transport and cobalamin biosynthesis. The megaplasmid also codes for alkane degradation and was shown to play an essential role in MTBE degradation through plasmid-curing experiments. Discrepancies between the insertion sequence element distribution patterns, the distributions of best BLASTP hits among major phylogenetic groups, and the G+C contents of the chromosome (69.2%) and plasmid (66%), together with comparative genome hybridization experiments, suggest that the plasmid was recently acquired and apparently carries the genetic information responsible for PM1's ability to degrade MTBE. Comparative genomic hybridization analysis with two PM1-like MTBE-degrading environmental isolates ( similar to 99% identical 16S rRNA gene sequences) showed that the plasmid was highly conserved (ca. 99% identical), whereas the chromosomes were too diverse to conduct resequencing analysis. PM1's genome sequence provides a foundation for investigating MTBE biodegradation and exploring the genetic regulation of multiple biodegradation pathways in M. petroleiphilum and other MTBE-degrading beta-proteobacteria.

The complete genome sequence showed that T. fusca has a single circular chromosome of 3,642,249 bp predicted to encode 3,117 proteins and 65 RNA species with a coding density of 85%. Genome analysis revealed the existence of 29 putative glycoside hydrolases in addition to the previously identified cellulases and xylanases. The glycosyl hydrolases include enzymes predicted to exhibit mainly dextran/starch- and xylan-degrading functions. T. fusca possesses two protein secretion systems: the sec general secretion system and the twin-arginine translocation system. Several of the secreted cellulases have sequence signatures indicating their secretion may be mediated by the twin-arginine translocation system. T. fusca has extensive transport systems for import of carbohydrates coupled to transcriptional regulators controlling the expression of the transporters and glycosylhydrolases. In addition to providing an overview of the physiology of a soil actinomycete, this study presents insights on the transcriptional regulation and secretion of cellulases which may facilitate the industrial exploitation of these systems.

Clusters containing iron nanoparticles ( similar to 50 nm in diameter) were found to combust entirely in the solid state due to the high surface-to-volume ratio typical of nanoparticles. Optical temperature measurements indicated that combustion was rapid similar to 500 ms), and occurred at relatively low peak combustion temperatures (1000-1200 K). Combustion produces a mixture of Fe(III) oxides. X-ray diffraction and gravimetric analysis indicated that combustion was nearly complete (93-95% oxidation). Oxide nanoparticles could be readily reduced at temperatures between 673 K and 773 K using hydrogen at 1 atm pressure, and then passivated by the growth of a thin oxide layer. The nanostructuring of the particles is retained throughout the combustion-regeneration cycle. Modeling of the combustion process is in good agreement with observed combustion characteristics.

At the Fort Benning Military Installation (near Columbus, Georgia), spatial variability in intensity of military training results in a wide range of intensities of upland disturbance in stream catchments. A set of 8 streams in catchments spanning this upland disturbance gradient was selected for investigation of the impact of disturbance intensity on hydrodynamics and nutrient uptake. The size of transient storage zones and rates of NH sub(4) super(+) uptake in all study streams were among the lowest reported in the literature. Upland disturbance did not appear to influence stream hydrodynamics strongly, but it caused significant decreases in instream nutrient uptake. In October 2003, coarse woody debris (CWD) was added to one half of the study streams (spanning the disturbance gradient) in an attempt to increase hydrodynamic and structural complexity, with the goals of enhancing biotic habitat and increasing nutrient uptake rates. CWD additions had positive short-term (within 1 mo) effects on hydrodynamic complexity (water velocity decreased and transient storage zone cross-sectional area, relative size of the transient storage zone, fraction of the median travel time attributable to transient storage over a standardized length of 200 m, and the hydraulic retention factor increased) and nutrient uptake (NH sub(4) super(+) uptake rates increased). Our results suggest that water quality in streams with intense upland disturbances can be improved by enhancing instream biotic nutrient uptake capacity through measures such as restoring stream CWD.

Cr6+ was reduced to Cr3+ in the non-sterilized lactate, ethanol, and acetate-amended soils; however, soils amended with lactate reduced significantly more chromium. Soils sterilized by gamma -irradiation reduced almost no Cr6+, indicating that Cr6+ reduction was at least indirectly biological in nature. Analyses of small subunit (ssu) rRNA genes amplified from the column sediments showed significantly different bacterial populations within the amended soils that may be due to carbon source or to aerobic micropockets within the sediment columns.

AN - 70347043; 17408188 AB - A panel of international experts was convened in Madison, Wisconsin, in 2005, as part of the 8th International Conference on Mercury as a Global Pollutant. Our charge was to address the state of science pertinent to source attribution, specifically our key question was: "For a given location, can we ascertain with confidence the relative contributions of local, regional, and global sources, and of natural versus anthropogenic emissions to mercury deposition?" The panel synthesized new research pertinent to this question published over the past decade, with emphasis on four major research topics: long-term anthropogenic change, current emission and deposition trends, chemical transformations and cycling, and modeling and uncertainty. Within each topic, the panel drew a series of conclusions, which are presented in this paper. These conclusions led us to concur that the answer to our question is a "qualified yes," with the qualification being dependent upon the level of uncertainty one is willing to accept. We agreed that the uncertainty is strongly dependent upon scale and that our question as stated is answerable with greater confidence both very near and very far from major point sources, assuming that the "global pool" is a recognizable "source." Many regions of interest from an ecosystem-exposure standpoint lie in between, where source attribution carries the greatest degree of uncertainty.

Recent studies of uranium(VI) bioreduction in the presence of environmentally relevant levels of calcium revealed limited and slowed uranium(VI) reduction and the formation of a Ca-UO (sub 2) -CO (sub 3) complex. However, the stoichiometry of the complex is poorly defined and may be complicated by the presence of a Na-UO (sub 2) -CO (sub 3) complex. Such a complex might exist even at high calcium concentrations, as some UO (sub 2) -CO (sub 3) complexes will still be present. The number of calcium and/or sodium atoms coordinated to a uranyl carbonate complex will determine the net charge of the complex. Such a change in aqueous speciation of uranium(VI) in calcareous groundwater may affect the fate and transport properties of uranium. In this paper, we present the results from X-ray absorption fine structure (XAFS) measurements of a series of solutions containing 50 mu M uranium(VI) and 30 mM sodium bicarbonate, with various calcium concentrations of 0-5mM. Use of the data series reduces the uncertainty in the number of calcium atoms bound to the UO (sub 2) -CO (sub 3) complex to approximately 0.6 and enables spectroscopic identification of the Na-UO (sub 2) -CO (sub 3) complex. At nearly neutral pH values, the numbers of sodium and calcium atoms bound to the uranyl triscarbonate species are found to depend on the calcium concentration, as predicted by speciation calculations.

Individual cell microanalysis by transmission electron microscopy (TEM) using electron energy-loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDXS) demonstrates Cr(II) concentrated near the cytoplasmic membrane, suggesting the terminal reduction pathway is intracellularly localized. Further, estimated cellular Cr(II) concentrations are relatively high at upwards of 0.03-0.09g Cr/g bacterium. Accumulation of Cr(II) is observed in S. oneidensis cells prior to the formation of submicron-sized precipitates of insoluble Cr(III) on their surfaces. Furthermore, under anaerobic conditions, Cr(III) precipitates that encrust cells are shown to contain Cr(II) that is likely bound in the net negatively charged extracellular biopolymers which can permeate the surfaces of the precipitates. In otherwise nearly identical incubations, Cr(III) precipitate formation was observed in cultures maintained anaerobic with bubbled nitrogen but not in three replicate cultures in an anaerobic chamber.

Instead of approximating the time derivative by finite difference, the proposed method approximates the exact solution of the ordinary differential equations. The method is unconditionally stable; the accuracy depends only on the approximation accuracy of the stress; for piecewise constant or linear stress (e.g., pumping) in time, the solution can be exact; and the time step size can be as long as a stress period. The tradeoff is the computational cost, which can be reduced by using larger and less variable time step sizes. Two examples are given to show the performance of the semianalytical time integration method.

Changes in patterns of land cover through time affect the ecological system by altering the proportion and distribution of habitats for species that these cover types support. Landscape patterns, therefore, are important indicators of land-use impacts, past and present, upon the landscape. This analysis of landscape pattern began with a landscape characterization based on witness tree data from 1827 and the 1830s and remotely sensed data from 1974, 1983, 1991, and 1999. The data from the early 1800s, although coarse, were useful in characterizing the historical range of variability in ecological conditions for the area. The steps for the analysis involved the creation of a land-cover database and a time series of land-cover maps, computation of landscape metrics, and evaluation of changes in those metrics over time as evidenced in the land-cover maps. We focused on five cover types (bare/developed land, deciduous forest, mixed forest, pine forest, and non-forest vegetated land), for they reveal information important to resources management at Fort Benning. An examination of land-cover class and landscape metrics, computed from the maps, indicated that a suite of metrics adequately describes the changing landscape at Fort Benning, Georgia. The most appropriate metrics were percent cover, total edge (km), number of patches, descriptors of patch area, nearest neighbor distance, the mean perimeter-to-area ratio, shape range, and clumpiness. Identification of such ecological indicators is an important component of building an effective environmental monitoring system.

AN - 70563201; 17062600 AB - The biokinetic and dosimetric model of the gastrointestinal (GI) tract applied in current documents of the International Commission on Radiological Protection (ICRP) was developed in the mid-1960s. The model was based on features of a reference adult male and was first used by the ICRP in Publication 30, Limits for Intakes of Radionuclides by Workers (Part 1, 1979). In the late 1990s an ICRP task group was appointed to develop a biokinetic and dosimetric model of the alimentary tract that reflects updated information and addresses current needs in radiation protection. The new age-specific and gender-specific model, called the Human Alimentary Tract Model (HATM), has been completed and will replace the GI model of Publication 30 in upcoming ICRP documents. This paper discusses the basis for the structure and parameter values of the HATM, summarises the uncertainties associated with selected features and types of predictions of the HATM and examines the sensitivity of dose estimates to these uncertainties for selected radionuclides. Emphasis is on generic biokinetic features of the HATM, particularly transit times through the lumen of the alimentary tract, but key dosimetric features of the model are outlined, and the sensitivity of tissue dose estimates to uncertainties in dosimetric as well as biokinetic features of the HATM are examined for selected radionuclides.

AN - 70144927; 18192667 AB - The calculation of absorbed dose in skeletal tissues at radiogenic risk has been a difficult problem because the relevant structures cannot be represented in conventional geometric terms nor can they be visualised in the tomographic image data used to define the computational models of the human body. The active marrow, the tissue of concern in leukaemia induction, is present within the spongiosa regions of trabecular bone, whereas the osteoprogenitor cells at risk for bone cancer induction are considered to be within the soft tissues adjacent to the mineral surfaces. The International Commission on Radiological Protection (ICRP) recommends averaging the absorbed energy over the active marrow within the spongiosa and over the soft tissues within 10 microm of the mineral surface for leukaemia and bone cancer induction, respectively. In its forthcoming recommendation, it is expected that the latter guidance will be changed to include soft tissues within 50 microm of the mineral surfaces. To address the computational problems, the skeleton of the proposed ICRP reference computational phantom has been subdivided to identify those voxels associated with cortical shell, spongiosa and the medullary cavity of the long bones. It is further proposed that the Monte Carlo calculations with these phantoms compute the energy deposition in the skeletal target tissues as the product of the particle fluence in the skeletal subdivisions and applicable fluence-to-dose-response functions. This paper outlines the development of such response functions for photons.

Data indicate that elderly persons use more residential energy than younger persons. In this time of steeply rising energy costs, energy is an especially important financial issue for the elderly with low and/or fixed incomes. As the absolute number of elderly as well as their proportion of the total US population both continue to increase, energy and the elderly population looms as another energy policy challenge.

On average, biofilms had the highest biomass followed by service water, and then fracture water. Quinone-based biomass estimates were higher for samples containing Archaea, as determined by SSU rRNA gene analysis. This higher estimate is due to the quinone assay detecting archaeal menaquinones while the PLFA assay does not detect archaeal ether-linked phospholipids. When PLFA community composition was examined, air samples were dominated by normal saturates and polyunsaturates, whereas service water was dominated by monounsaturates, indicating dominance by eukaryotic microorganisms and Gram-negative bacteria, respectively. In contrast, fracture water samples exhibited diverse microbial community profiles. In some samples the ratio of cyclopropyl to monounsaturated fatty acid indicated that the microbial communities may be constrained by conditions such as limited nutrients. The quinone profiles for samples exposed to oxygen showed a higher abundance of ubiquinones, while anoxic samples had higher abundances of menaquinones. The ratio of ubiquinone to menaquinone indicates that many of the fracture waters have been exposed to anoxic conditions for a long time. When the PLFA profiles were combined with the physical and chemical data for redundancy ordination analysis, temperature, pH, Eh, and concentrations of chloride, sulfate and nitrate were indicated as parameters that influenced changes in the microbial community composition. Continued investigations into the deep terrestrial subsurface will provide a better understanding of the microbial communities and their biogeochemical processes.

Magnetite-rich Banded Iron Formations (BIFs) and secondary hematite-rich iron ore formations have been linked to the oxygenation of the ocean and atmosphere, assuming redox transformation of magnetite-hematite. However, magnetite-hematite transformation may proceed though a non-redox (i.e., acid-base) reaction (1): Fe (sub 3) O (sub 4) + 2H (super +) Fe (sub 2) O (sub 3) + Fe (super 2+) + H (sub 2) O. Magnetite is transformed to hematite as a result of leaching Fe (super 2+) from magnetite while hematite is transformed to magnetite as a result of incorporating Fe (super 2+) into hematite. We have examined the reactions (forward and reverse) using a hydrothermal cell with hydrogen electrodes for pH measurements and a hydrogen-permeable membrane for pH (sub 2) measurements The experiments were conducted at 100-250 degrees C under highly reducing conditions (pH (sub 2) = 0.5-50 bar) and mildly acid conditions (pH = 4-6). After the system reached a steady state, iron concentration in the withdrawn sample solutions was measured. The residual solid was analyzed using XRD, SEM and HRTEM. Our experiments have demonstrated that euhedral crystals of hexagonal dipyramidal hematite grow rapidly by reaction between magnetite and acid solutions at T Fe (super 2+) + 4/3H (sub 2) O. No hematite was found in the residual solid from experiments at the temperature. The results of our studies suggest magnetite and hematite act as an acid-base buffer, rather than a redox buffer in low temperature environments. Because magnetite-hematite transformation does not require a redox reaction, secondary hematite-rich iron ore developed from BIFs may have formed by subsurface reaction between magnetite and acidic hydrothermal solutions at T < or = 200 degrees C.

We posit that high temporal estimates of anthropogenic CO2 fluxes will impact the seasonal cycle of atmospheric CO2 concentrations and will impact inversion calculations. Implementing a dual harmonic numerical treatment as a function of latitude the annual fluxes are decomposed into monthly flux estimates. Using these monthly flux estimates we then use the NASA PCTM to transport the annual and monthly fluxes in the atmosphere. We find that the use of monthly fluxes makes a significant difference in the seasonal cycle of atmospheric CO2 in and near those regions where anthropogenic CO2 is released to the atmosphere. Local variations of 2-6 ppm CO2 in the seasonal cycle amplitude are simulated. We also find that in the mid latitudes near the sources synoptic scale atmospheric circulations are important in the winter and that boundary layer venting and rectifier effects are more important in the summer. These finding have implications for inverse models that attempt to estimate surface source/sink regions especially when the surface sinks are co-located with regions of strong anthropogenic CO2 emissions.

A new metric is developed for testing the applicability of extreme value theory on time series data. The shape parameter and return levels are computed and visualized along with their confidence bounds at each spatial location and for multiple time windows. In addition, spatio-temporal correlations and tail dependence are computed and visualized for each pair of points in space over different time windows. The new approaches are applied to observed daily precipitation in South America available at 2.5 degree spatial grids from 1940 to 2004, as well as daily precipitation simulated from the state-of-the-art IPCC (Intergovernmental Panel on Climate Change) model, which in turn are available at 1.4 degree spatial grids from 1870 to 2100. New insights are obtained about precipitation extremes in South America, specifically on the spatio-temporal patterns and trends within or among the extreme values, comparison of dependence among the extremes in space and time with a traditional measure of correlation computed from all available values, and on the ability of climate models to simulate the extreme values as well as the trends or dependence structures within and among these extremes.

Experimental study AN - 20249137; 8549977 AB - Tensile and Charpy specimens of 9Cr-1MoVNb (modified 9Cr-1Mo) and 12Cr-1MoVW (Sandvik HT9) steels and these steels doped with 2% Ni were irradiated at 300 and 400 DGC in the High Flux Isotope Reactor (HFIR) up to approximately 12 dpa and at 393 DGC in the Fast Flux Test Facility (FFTF) to approximately 15 dpa. In HFIR, a mixed-spectrum reactor, (n, alpha ) reactions of thermal neutrons with 58Ni produce helium in the steels. Little helium is produced during irradiation in FFTF. After HFIR irradiation, the yield stress of all steels increased, with the largest increases occurring for nickel-doped steels. The ductile-brittle transition temperature (DBTT) increased up to two times and 1.7 times more in steels with 2% Ni than in those without the nickel addition after HFIR irradiation at 300 and 400 DGC, respectively. Much smaller differences occurred between these steels after irradiation in FFTF. The DBTT increases for steels with 2% Ni after HFIR irradiation were 2-4 times greater than after FFTF irradiation. Results indicated there was hardening due to helium in addition to hardening by displacement damage and irradiation-induced precipitation.

A systematic trend of the methane yields for the different molecular species compared at the same impact energy/D is observed: while all three species lead to methane yields that coincide within the experimental uncertainty at the high energy end of the investigated range, at lower energies the yields diverge by progressively larger amounts, with the incident triatomic molecular ion leading to the largest yields per atom, and the atomic ion to the smallest. The difference at the lowest investigated energy (10 eV/D) is about a factor of two. Total chemical sputtering yields obtained by classical molecular dynamic simulations also indicate that molecular projectiles lead to larger yields per atom than atomic projectiles. The energy dependence of the total yield increase obtained by the simulations, however, is different than that observed experimentally for methane production.

On agricultural lands, changes in land management can cause changes in CO2 emissions from fossil fuel use, agricultural lime, and decomposition of soil carbon. Changes in off-site emissions can occur from the manufacturing of fertilizers, pesticides, and agricultural lime. We are developing a full carbon accounting framework that can be used for estimates of on-site net carbon flux or for full greenhouse gas accounting at a high spatial resolution. Estimates are based on the assimilation of national inventory data, soil carbon dynamics based on empirical analyses of field data, and Landsat-derived remote sensing products with 30x30m resolution. We applied this framework to a mid-western region of the US that consists of 679 counties approximately centered around Iowa. We estimate the 1990 baseline soil carbon for this region to be 4,099 Tg C to a 3m maximum depth. Soil carbon accumulation of 57.3 Tg C is estimated to have occurred in this region between 1991-2000. Without accounting for soil carbon loss associated with changes to more intense tillage practices, our estimate increases to 66.3 Tg C. This indicates that on-site permanence of soil carbon is approximately 86% with no additional economic incentives provided for soil carbon sequestration practices. Total net carbon flux from the agricultural activities in the Midwestern US in 2000 is estimated at about - 5 Tg C. This estimate includes carbon uptake, decomposition, harvested products, and on-site fossil fuel emissions. Therefore, soil carbon accumulation offset on-site emissions in 2000. Our carbon accounting framework offers a method to integrate new inventory and remote sensing data on an annual basis, account for alternating annual trends in land management without the need for model equilibration, and provide a transparent means to monitor changes soil carbon. Our method of integration is capable of estimating regional or national changes in soil carbon while still representing heterogeneity at the sub-county level. Future research will include predictive changes in soil carbon and net carbon flux based on socio-economic drivers, and a sensitivity analysis using high- resolution remote sensing products.

Virtually all processes responsible for storage of carbon in the vegetation and soils of both managed and unmanaged ecosystems are significantly influenced by temperature, precipitation and other climate variables. Accordingly, forecasts of terrestrial carbon sequestration must include the influence of climate on the carbon dynamics of managed and unmanaged ecosystems as well as including purposeful human intervention in the carbon cycling of managed ecosystems. However, the future climates used in carbon management forecasts are often derived from coupled atmosphere-ocean general circulation models that do not include an interactive carbon cycle, and thus they miss important climate-carbon cycle feedbacks. In particular, such analyses miss the feedbacks between purposeful carbon management, its influence on atmospheric CO$_{2}$ and thus climate, and the subsequent influence of climate on managed (and unmanaged) ecosystem carbon sequestration. This decoupling is a source of uncertainty in evaluating potential carbon management options. Here we describe modeling results that analyze components of this uncertainty. We describe a model of global carbon management that includes atmosphere, ocean and terrestrial (managed and unmanaged) carbon cycling. We describe aspects of coupling the carbon cycle model with energy-economic systems. We then present simulations using a future climate generated by an independent climate model. The projected changes in climate release CO$_{2}$ from the terrestrial biosphere (primarily through soil response to warmer temperatures), resulting in higher future CO$_{2}$ concentrations than in the absence of climate change (approximately 50ppm higher by 2100). These simulations indicate that future carbon management must compensate for carbon released in response to feedbacks from climate change as well as the emissions from energy production.

This study investigated the relationship between flow pattern and removal of dissolved phosphorus (P) within vegetative filter strips treating milk house wastewater on two dairy farms located in the Catskills/Delaware watersheds, which are the source of drinking water for New York. Numerous surface and subsurface wells were monitored in the two vegetative filter strips, and chloride tracer was applied to evaluate flow paths. Soluble reactive P concentrations were measured during regular milk house wastewater discharges prior to and during chloride application. Chloride breakthrough showed wastewater flowing preferentially through the vegetative filter strip. The soluble reactive P concentrations were significantly higher within the preferential flow paths compared to the other less saturated parts of the vegetative filter strip. Removal of soluble reactive P was minimal in a saturated flow path, which persisted for 15 m (50 ft) and only began to occur as the wastewater eventually dissipated into drier soil areas. Although soluble reactive P concentrations were eventually reduced to below 0.2 mg L super(-1) (0.2 ppm) at the bottom of both vegetative filter strips, these results suggest the importance of proper design, site and location characteristics, and maintenance to assure uniform distribution and infiltration of wastewater within the vegetative filter strip to maintain effectiveness and prolong the life of the vegetative filter strip.

AN - 19850050; 7342644 AB - In a series of experiments at the DOE FRC site in Oak Ridge we have been examining the interactions among electron donors, rates of uranium, nitrate, and sulfate reduction and community structure. We have found consistently high rates of nitrate and uranium reduction with some electron donors (e.g., glucose and ethanol). However, while methanol stimulation consistently promoted nitrate and sulfate reduction, in only one of five independent experiments with different sediment samples was U reduction stimulated by methanol addition. Four of the five sediment samples for these experiments were taken within three meters of each other in a zone with consistent geochemical characteristics. One of these four samples was the only sample in which U reduction was observed with the methanol addition. After this first observation of methanol stimulation of U reduction, we confirmed the result by repeating the methanol addition on additional archived sediment material from the same sample. Thus, there appear to be sample-scale heterogeneities in the community structure with a relatively uncommon community able to reduce U when stimulated with methanol. We are currently sampling and screening a broader array of sediment samples from the site to determine the prevalence of this community type. Characterization of the microbial community from the initial five experiments using a variety of methods (PLFA, TRFLP, PCR) indicated that there were substantial differences in the community structure related to the type of electron donor added. Further analyses using similar techniques on additional methanol stimulated samples and profiling of the communities using a functional gene array are ongoing. These community composition measurements will be related to uranium reduction rates by non-linear data analysis techniques to understand the specific differences in the communities stimulated by methanol that result in the observed differences in the ability to reduce U.

Antibiotic elements, lanthanide (Nd, Gd, Tb, Ho, and Er)- substituted magnetites were produced by microbial fermentation using LxFe1-xOOH, where x was up to 0.02 which is equivalent to 0.72 mM. Combining lanthanides into the akaganeite precursor phase mitigated some of the toxicity when compared to the traditional method by using pure akaganeite and the dissolved L-salt form. This new technique showed that an upper limit of L-concentrations between 0.02 and 0.1 mM might suppress bacterial activity. At the equivalent L-cation mole fraction, the traditional method increased the concentration of soluble toxic L ions in the final media. The precursor method enabled production of microbially synthesized L-substituted magnetite with an L-concentration 36-fold greater than could be obtained when the lanthanides were added as soluble salts. These results were confirmed by protein assay. The increase of L-concentration in the magnetite evidently manipulates its physical properties such as decreasing Curie temperature and decreasing saturation magnetism of L- substituted magnetite. This mixed precursor method can therefore be used to extend the application for nanofermentation and other bacterial synthesis fields where there is a need for economically low- energy consumable microbial production of nanoscale materials that should involve toxic or inhibitory elements to bacterial growth.

The role of GlnK in nitrogen regulation has been studied in a variety of bacteria but previously has been uncharacterized in the purple nonsulfur anoxygenic phototropic bacterium Rhodopseudomonas palustris. R. palustris has tremendous metabolic versatility in its modes of energy generation and carbon metabolism, and it employs a sensitive nitrogen-ammonium regulation system that may vary from that of other commonly studied bacteria. In R. palustris, there are three annotated forms of pII proteins: GlnK1, GlnK2, and GlnB. Here we describe, for the first time, the characterization of GlnK1, GlnK2, and GlnB modifications as a response to nitrogen availability, thereby providing information about how this bacterium regulates the AmtB ammonium transporter and glutamine synthetase, which controls the rate of glutamate to glutamine conversion. Using a strategy of creating C-terminally tagged GlnK and GlnB proteins followed by tandem affinity purification in combination with top- down mass spectrometry, four isoforms of the GlnK2 and GlnB proteins and two isoforms of the GlnK1 protein were characterized at high resolution and mass accuracy. Wild-type or endogenous expression of all three proteins was also examined under normal ammonium conditions and ammonium starvation to ensure that the tagging and affinity purification methods employed did not alter the natural state of the proteins. All three proteins were found to undergo uridylylation under ammonium starvation conditions, presumably to regulate the AmtB ammonium transporter and glutamine synthetase. Under high-ammonium conditions, the GlnK1, GlnK2, and GlnB proteins are unmodified. This experimental protocol involving high-resolution mass spectrometry measurements of intact proteins provides a powerful method of examining the posttranslational modifications that play a crucial role in both the regulation of the AmtB ammonium transporter and glutamine synthetase within R. palustris.

AN - 68837327; 16957260 AB - The biological impact of 24-h ("chronic") chromium(VI) [Cr(VI) or chromate] exposure on Shewanella oneidensis MR-1 was assessed by analyzing cellular morphology as well as genome-wide differential gene and protein expression profiles. Cells challenged aerobically with an initial chromate concentration of 0.3 mM in complex growth medium were compared to untreated control cells grown in the absence of chromate. At the 24-h time point at which cells were harvested for transcriptome and proteome analyses, no residual Cr(VI) was detected in the culture supernatant, thus suggesting the complete uptake and/or reduction of this metal by cells. In contrast to the untreated control cells, Cr(VI)-exposed cells formed apparently aseptate, nonmotile filaments that tended to aggregate. Transcriptome profiling and mass spectrometry-based proteomic characterization revealed that the principal molecular response to 24-h Cr(VI) exposure was the induction of prophage-related genes and their encoded products as well as a number of functionally undefined hypothetical genes that were located within the integrated phage regions of the MR-1 genome. In addition, genes with annotated functions in DNA metabolism, cell division, biosynthesis and degradation of the murein (peptidoglycan) sacculus, membrane response, and general environmental stress protection were upregulated, while genes encoding chemotaxis, motility, and transport/binding proteins were largely repressed under conditions of 24-h chromate treatment.

The low- delta T scenario had a cumulative (2003-2025) energy increase of 1.09 quadrillion Btu (quads) for cooling/heating demand. Northeastern states had net energy reductions for cooling/heating over the entire period, but in most other regions energy increases for cooling outweighed energy decreases for heating. The high- delta T scenario had significantly increased warming, especially in winter, so decreased heating needs led to a cumulative (2003-2025) heating/cooling energy decrease of 0.82 quads. In both scenarios, CO sub(2) emissions increases from electricity generation outweighed CO sub(2) emissions decreases from reduced heating needs. The results reveal the intricate energy-economy structure that must be considered in projecting consequences of climate warming for energy, economics, and fossil-fuel carbon emissions.

The current treatment facility is aging and is optimized to remove 90 Sr, but future wastewaters are likely to contain mostly activated metals, such as 51 Cr and 64 Cu. Other low- volume wastewaters may contain trace concentrations of Hg and U. Complexing ion- exchange resins and other specialized sorbents were tested for removing trace concentrations of heavy metals. Short-term column tests and batch loading tests were conducted using a surrogate wastewater and various sorbents. These tests showed that metal uptake was very rapid, and that good removal and relatively high loadings could be achieved from a very dilute wastewater surrogate. Forager M-TU (Dynaphore, Inc.) showed the best overall results, removing 91.9% of the Cr, 99.3% of the Cu, >99.7% of the Hg, and >99.9% of the U with a contact time of 120 seconds in a short-term column test.

Several cores were collected near four former unlined adjoining waste disposal ponds. The cores were collected, described, analyzed for U, and compared with ground water geochemistry from surrounding multilevel wells. At some locations, acidic U-contaminated ground water was found to preferentially flow in small remnant fractures weathering the surrounding shale (nitric acid extractable U [U sub(NA)] usually < 50 mg kg super(-1)) into thin (<25 cm) Fe oxide- rich clayey seams that retain U (U sub(NA) 239 to 375 mg kg super(-1)). However, greatest contaminant transport occurs in a 2 to 3 m thick more permeable stratigraphic transition zone located between two less permeable, and generally less contaminated zones consisting of (i) overlying unconsolidated saprolite (U sub(NA) < 0.01 to 200 mg kg super(-1)) and (ii) underlying less-weathered bedrock (U sub(NA) generally < 0.01 to 7 mg kg super(-1)). In this transition zone, acidic (pH < 4) U-enriched ground water (U of 38 mg L super(-1)) has weathered away calcite veins resulting in greater porosity, higher hydraulic conductivity, and higher U contamination (U sub(NA) 106 to 745 mg kg super(-1)) of the weathered interbedded shale and sandstone. These characteristics of the transition zone produce an interval with a high flux of contaminants that could be targeted for remediation.

One treatment is a commercial carburization process in which carbon is impregnated at low temperature at concentrations up to 6 wt% in supersaturated solid solution to depths of about 33 is a subset of m. The surface hardness of 316L steel is raised from 150 to 200HV0.05 (micro-Vickers hardness number at a 50 g load) to 1000-1200HV0.05. It is shown that during subsequent electron beam welding the supersaturated carburized layer in the heat affected zone decomposes to a tiered microstructure of carbide phases in austenite. The hardness of this complex decomposition microstructure is in the range 530-1200HV0.05, depending on the exposure temperature, the local carbon level, and the size of the carbide particles. To test whether the carburized solid solution layer would break down under atomic displacements from proton and neutron irradiation in service, specimens of annealed and 20% cold-rolled 316LN steel were neutron irradiated to 1 dpa at 60-100 DGC. No softening of the layer was detected. Rather, the hardness of the layers was increased by 2-12%, compared to increases of 81% and 43% for the annealed and 20% cold rolled substrate materials, respectively. Optical microscopy examinations of the surfaces of the as-carburized-and-irradiated specimens revealed no sign of decomposition attributable to irradiation.

Sequencing and annotation of the genome revealed a single circular chromosome (3,481,691 bp; G+C content of 50.4%) and a plasmid (40,420 bp) that contain 3,052 and 41 candidate protein-encoding genes, respectively. The genes encoding proteins necessary for the function of known modes of lithotrophy and autotrophy were identified. Contrary to betaproteobacterial nitrifier genomes, the N. oceani genome contained two complete rrn operons. In contrast, only one copy of the genes needed to synthesize functional ammonia monooxygenase and hydroxylamine oxidoreductase, as well as the proteins that relay the extracted electrons to a terminal electron acceptor, were identified. The N. oceani genome contained genes for 13 complete two-component systems. The genome also contained all the genes needed to reconstruct complete central pathways, the tricarboxylic acid cycle, and the Embden-Meyerhof-Parnass and pentose phosphate pathways. The N. oceani genome contains the genes required to store and utilize energy from glycogen inclusion bodies and sucrose. Polyphosphate and pyrophosphate appear to be integrated in this bacterium's energy metabolism, stress tolerance, and ability to assimilate carbon via gluconeogenesis. One set of genes for type I ribulose-1,5-bisphosphate carboxylase/oxygenase was identified, while genes necessary for methanotrophy and for carboxysome formation were not identified. The N. oceani genome contains two copies each of the genes or operons necessary to assemble functional complexes I and IV as well as ATP synthase (one H super(+)-dependent F sub(0)F sub(1) type, one Na super(+)-dependent V type).

Key facility performance parameters are summarized and plans for initial operation are described. Early efforts produced a conceptual design in 1997; the project itself was initiated in 1999, with the official groundbreaking taking place in December of 1999. As of April 2005 building construction was complete and the overall project was more than 90% complete. The design of the target and surrounds are finished and the first target was installed in June 2005. First beam on target is expected in June, 2006. The engineering design of the target region is described. The key systems comprise the mercury target, moderator and reflector assemblies, remote handling systems, utilities and shielding. Through interactions with the 1 GeV proton beam, the target, moderators and reflectors produce short pulse neutrons in thermal energy ranges, which are transported to a variety of neutron scattering instruments. The mercury target module itself is described in more detail. Materials issues are expected to govern the overall lifetime and have influenced the design, fabrication and planned operation. A wide range of materials research and development has been carried out to provide experimental data and analyses to ensure the satisfactory performance of the target and to set initial design conditions. Materials R&D concentrated mainly on cavitation erosion, radiation effects, and mercury compatibility issues, including investigations of the mechanical properties during exposure to mercury. Questions that would require future materials research are discussed.

The detection method is based on the diffusion of the radioactive gas in the gel material, and the subsequent measurement of trapped products of the natural decay of radon by gamma spectrometry. From the several radon daughters with gamma radiation emission ( super(214)Pb, super(214)Bi, super(214)Po, super(210)Pb, super(210)Po), two elements, super(214)Pb (0.352 MeV) and super(214)Bi (0.609 MeV), were chosen for the analysis in this work; in order to determine the best sensitivity, corrections were made for the short half-life of the analysed isotopes. For the gamma spectrometry analysis, a hyperpure germanium solid state detector was used, associated with a PC multichannel analyser card with Maestro super( registered ) and Microsoft super( registered ) Excel super( registered ) software. The results show the viability of the method: a linear response in a wide radon concentration range (450-10,000 Bq m super(-3)), reproducibility of data, easy handling and low cost of the gel material. This detection methodology opens new possibilities for measurements of radon and other radioactive gases.

We predicted that diurnal and day-to-day variations in NO sub(3) super(-) uptake rate would be larger in the West Fork than in the East Fork in early spring because of higher rates of primary productivity resulting from a more stable substratum in the West Fork. We also predicted minimal diurnal variations in both streams in late spring after forest leaf emergence when light levels and primary productivity are uniformly low. Reach-scale rates of gross primary production (GPP) were determined using the diurnal dissolved O sub(2) change technique, and reach-scale rates of NO sub(3) super(-) uptake were determined by tracer super(15)N-NO sub(3) super(-) additions. In the West Fork, significant diurnal and day-to-day variations in NO sub(3) super(-) uptake were related to variations in light level and primary productivity in early spring but not in late spring, consistent with our predictions. In early spring, West Fork NO sub(3) super(-) uptake rates were 2 to 3 x higher at midday than during predawn hours and 50% higher on 2 clear days than on an overcast day several days earlier. In the East Fork, early spring rates of GPP were 4 to 5 x lower than in the West Fork and diurnal and day-to-day variations in NO sub(3) super(-) uptake rates were <30%, considerably lower than in the West Fork. However, diurnal variations in NO sub(3) super(-) uptake rates were greater in late spring in the East Fork, possibly because of diurnal variation in water temperature. Our results indicate the important role of autotrophs in nutrient uptake in some forested streams, particularly during seasons when forest vegetation is dormant and light levels are relatively high. Our results also have important implications for longer-term assessments of N cycling in streams that rely on daytime measurements or measurements only under limited weather conditions (i.e., clear days).

Physicochemical and mineralogical characterization of U-contaminated soils in deeply weathered saprolite at Area 2 of the DOE Field Research Center (FRC) site, Oak Ridge, TN, was accomplished to examine the feasibility of bioremediation. Concentrations of U in soil-saprolite (up to 291 mg kg super(-1) in oxalate-extractable U sub(o)) were closely related to low pH (ca. 4-5), high effective cation exchange capacity without Ca (64.7-83.2 cmol sub(c) kg super(-1)), amorphous Mn content (up to 9910 mg kg super(-1)), and the decreased presence of relative clay mineral contents in the bulk samples (i.e., illite 2.5-12 wt. %, average 32 wt. %). The pH of the fill material ranged from 7.0 to 10.5, whereas the pH of the saprolite ranged from 4.5 to 8. Uranium concentration was highest (about 300 mg kg super(-1)) at around 6 m below land surface near the saprolite-fill interface. The pH of ground water at Area 2 tended to be between 6 and 7 with U concentrations of about 0.9 to 1.7 mg L super(-1). These site specific characteristics of Area 2, which has lower U and nitrate contamination levels and more neutral ground water pH compared with FRC Areas 1 and 3 (ca. 5.5 and <4, respectively), indicate that with appropriate addition of electron donors and nutrients bioremediation of U by metal reducing microorganisms may be possible.

comparison of X-ray standing wave, X-ray absorption spectroscopy, and density functional theory results AN - 51370732; 2007-106583 AB - Adsorption of Zn (super 2+) at the rutile TiO (sub 2) (110)-aqueous interface was studied with Bragg-reflection X-ray standing waves (XSW), polarization-dependent surface extended X-ray absorption fine structure (EXAFS) spectroscopy, and density functional theory (DFT) calculations to understand the interrelated issues of adsorption site, its occupancy, ion-oxygen coordination and hydrolysis. At pH 8, Zn (super 2+) was found to adsorb as an inner-sphere complex at two different sites, i.e., monodentate above the bridging O site and bidentate between two neighboring terminal O sites. EXAFS results directly revealed a four or fivefold first shell coordination environment for adsorbed Zn (super 2+) instead of the sixfold coordination found for aqueous species at this pH. DFT calculations confirmed the energetic stability of a lower coordination environment for the adsorbed species and revealed that the change to this coordination environment is correlated with the hydrolysis of adsorbed Zn (super 2+) . In addition, the derived adsorption locations and the occupancy factors of both sites from three methods agree well, with some quantitative discrepancies in the minor site location among the XSW, EXAFS, and DFT methods. Additional XSW measurements showed that the adsorption sites of Zn (super 2+) were unchanged at pH 6. However, the Zn (super 2+) partitioning between the two sites changed substantially, with an almost equal distribution between the two types of sites at pH 6 compared to predominantly monodentate occupation at pH 8.

In true stress-true strain analyses, however, the strain localization does not significantly affect macroscopic strain-hardening behavior. It was attempted to explain the strain-hardening behavior during strain localization in terms of long-range back stresses. In theoretical modeling the long-range back stress was formulated as a function of the number of residual pileup dislocations at a grain boundary and the number of localized bands formed in a grain. The strain-hardening rates in channel deformation were calculated for ten face-centered cubic (fcc) and body-centered cubic (bcc) metals. A few residual dislocations in each channel could account for the strain-hardening rates as high as those for uniform deformation. It was also shown that the strain-hardening behavior predicted by the long-range back stress model resembled the empirical strain-hardening behaviors, which result from both localized and non-localized deformations. The predicted plastic instability stress was comparable to the tensile test data.

This micro-organism is orangey in colour, Gram-negative, polarly flagellated, facultatively anaerobic and psychrotolerant (temperature range, 0- 42 not equal to ). No growth was observed with nitrate, nitrite, DMSO or thiosulfate as the electron acceptor and lactate as the electron donor. The major fatty acid detected in strain PV-4 super(T) was iso-C sub(15 : 0). Strain PV-4 super(T) had ubiquinones consisting mainly of Q-7 and Q-8, and possessed menaquinone MK-7. The DNA G+C content of the strain was 53.8 mol% and the genome size was about 4.5 Mbp. Phylogenetic analyses based on 16S rRNA gene sequences placed PV-4 super(T) within the genus Shewanella. PV-4 super(T) exhibited 16S rRNA gene sequence similarity levels of 99.6 and 97.5 %, respectively, with respect to the type strains of Shewanella aquimarina and Shewanella marisflavi. DNA from strain PV-4 super(T) showed low mean levels of relatedness to the DNAs of S. aquimarina (50.5 %) and S. marisflavi (8.5 %). On the basis of phylogenetic and phenotypic characteristics, the bacterium was classified in the genus Shewanella within a distinct novel species, for which the name Shewanella loihica sp. nov. is proposed. The type strain is PV-4 super(T) (=ATCC BAA- 1088 super(T)=DSM 17748 super(T)). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain PV-4 super(T) is DQ286387. The fatty acid compositions of strain PV-4 super(T) and S. aquimarina JCM 12193 super(T) are detailed in a supplementary table in IJSEM Online.

In addition to temporal transcriptomics, total protein, carbohydrate, lactate, acetate, and sulfate levels were measured. The microarray data were examined for statistically significant expression changes, hierarchical cluster analysis, and promoter element prediction and were validated by quantitative PCR. As the cells transitioned from the exponential phase to the stationary phase, a majority of the down-expressed genes were involved in translation and transcription, and this trend continued at the remaining times. There were general increases in relative expression for intracellular trafficking and secretion, ion transport, and coenzyme metabolism as the cells entered the stationary phase. As expected, the DNA replication machinery was down-expressed, and the expression of genes involved in DNA repair increased during the stationary phase. Genes involved in amino acid acquisition, carbohydrate metabolism, energy production, and cell envelope biogenesis did not exhibit uniform transcriptional responses. Interestingly, most phage-related genes were up-expressed at the onset of the stationary phase. This result suggested that nutrient depletion may affect community dynamics and DNA transfer mechanisms of sulfate-reducing bacteria via the phage cycle. The putative feoAB system (in addition to other presumptive iron metabolism genes) was significantly up-expressed, and this suggested the possible importance of Fe super(2+) acquisition under metal-reducing conditions. The expression of a large subset of carbohydrate-related genes was altered, and the total cellular carbohydrate levels declined during the growth phase transition. Interestingly, the D. vulgaris genome does not contain a putative rpoS gene, a common attribute of the delta -Proteobacteria genomes sequenced to date, and the transcription profiles of other putative rpo genes were not significantly altered. Our results indicated that in addition to expected changes (e.g., energy conversion, protein turnover, translation, transcription, and DNA replication and repair), genes related to phage, stress response, carbohydrate flux, the outer envelope, and iron homeostasis played important roles as D. vulgaris cells experienced electron donor depletion.

Taking advantage of multiple micrometeorological and ecophysiological measurements and a prolonged drought in the middle of the 2005 growing season at this site, we studied how soil moisture, atmospheric vapor pressure deficit (VPD), and net radiation affected surface energy partitioning. We stratified these factors to minimize potential confounding effects of correlation among them. We found that all three factors had direct effects on surface energy partitioning, but more important, all three factors also had crucial indirect effects. The direct effect of soil moisture was characterized by a rapid decrease in Bowen ratio with increasing soil moisture when the soil was dry and by insensitivity of Bowen ratio to variations in soil moisture when the soil was wet. However, the rate of decrease in Bowen ratio when the soil was dry and the level of soil moisture above which Bowen ratio became insensitive to changes in soil moisture depended on atmospheric conditions. The direct effect of increased net radiation was to increase Bowen ratio. The direct effect of VPD was very nonlinear: Increased VPD decreased Bowen ratio at low VPD but increased Bowen ratio at high VPD. The indirect effects were much more complicated. Reduced soil moisture weakened the influence of VPD but enhanced the influence of net radiation on surface energy partitioning. Soil moisture also controlled how net radiation influenced the relationship between surface energy partitioning and VPD and how VPD affected the relationship between surface energy partitioning and net radiation. Furthermore, both increased VPD and increased net radiation enhanced the sensitivity of Bowen ratio to changes in soil moisture and the effect of drought on surface energy partitioning. The direct and indirect effects of atmospheric conditions and soil moisture on surface energy partitioning identified in this paper provide a target for testing atmospheric general circulation models in their representation of land-atmosphere coupling.

AN - 68612439; 16820490 AB - Microarray technology provides the opportunity to identify thousands of microbial genes or populations simultaneously, but low microbial biomass often prevents application of this technology to many natural microbial communities. We developed a whole-community genome amplification-assisted microarray detection approach based on multiple displacement amplification. The representativeness of amplification was evaluated using several types of microarrays and quantitative indexes. Representative detection of individual genes or genomes was obtained with 1 to 100 ng DNA from individual or mixed genomes, in equal or unequal abundance, and with 1 to 500 ng community DNAs from groundwater. Lower concentrations of DNA (as low as 10 fg) could be detected, but the lower template concentrations affected the representativeness of amplification. Robust quantitative detection was also observed by significant linear relationships between signal intensities and initial DNA concentrations ranging from (i) 0.04 to 125 ng (r2 = 0.65 to 0.99) for DNA from pure cultures as detected by whole-genome open reading frame arrays, (ii) 0.1 to 1,000 ng (r2 = 0.91) for genomic DNA using community genome arrays, and (iii) 0.01 to 250 ng (r2 = 0.96 to 0.98) for community DNAs from ethanol-amended groundwater using 50-mer functional gene arrays. This method allowed us to investigate the oligotrophic microbial communities in groundwater contaminated with uranium and other metals. The results indicated that microorganisms containing genes involved in contaminant degradation and immobilization are present in these communities, that their spatial distribution is heterogeneous, and that microbial diversity is greatly reduced in the highly contaminated environment.

AN - 68607726; 16818613 AB - The primary cilium is a microtubule-based antenna-like structure that emanates from the surface of virtually all cells in the mammalian body. It is anchored to the cell by the basal body, which develops from the mother centriole of the centrosome in a manner that is coordinately regulated with the cell cycle. The primary cilium is a sensory organelle that receives both mechanical and chemical signals from other cells and the environment, and transmits these signals to the nucleus to elicit a cellular response. Recent studies revealed that multiple components of the Sonic hedgehog and platelet-derived growth factor receptor-alpha signal transduction pathways localize to the primary cilium, and that loss of the cilium blocks ligand-induced signaling by both pathways. In light of the major role that these pathways play in numerous types of cancer, we anticipate that the emerging discoveries being made about the function of the primary cilium in signaling pathways that are critical for embryonic development and tissue homeostasis in adults will also provide novel insights into the molecular mechanisms of carcinogenesis.

Fluid samples obtained from the injection and observation wells before CO (sub 2) injection showed a Na-Ca-Cl-type brine with 93,000 mg/L total dissolved solids (TDS) at near saturation with CH (sub 4) at reservoir conditions. Following CO (sub 2) breakthrough, samples showed sharp drops in pH (6.5-5.7), pronounced increases in alkalinity (100-3000 mg/L as HCO (sub 3) ) and Fe (30-1100 mg/L), and significant shifts in the isotopic compositions of H (sub 2) O, dissolved inorganic carbon (DIC), and CH (sub 4) . Geochemical modeling indicates that brine pH would have dropped lower but for the buffering by dissolution of carbonate and iron oxyhydroxides. This rapid dissolution of carbonate and other minerals could ultimately create pathways in the rock seals or well cements for CO (sub 2) and brine leakage. Dissolution of minerals, especially iron oxyhydroxides, could mobilize toxic trace metals and, where residual oil or suitable organics are present, the injected CO (sub 2) could also mobilize toxic organic compounds. Environmental impacts could be major if large brine volumes with mobilized toxic metals and organics migrated into potable groundwater. The delta (super 18) O values for brine and CO (sub 2) samples indicate that supercritical CO (sub 2) comprises approximately 50% of pore-fluid volume approximately 6 mo after the end of injection. Postinjection sampling, coupled with geochemical modeling, indicates that the brine gradually will return to its preinjection composition.

This approach is, however, sensitive to temperature and humidity under earth-surface conditions. This has made obsidian hydration dating more difficult, but potentially provides a unique tool for paleoclimatic reconstructions. In this paper we present the first successful application of this approach, based on combining laboratory-based experimental calibrations with archaeological samples from the Chalco site in the Basin of Mexico, dated using stratigraphically correlated (super 14) C results and measuring hydration depths by secondary ion mass spectrometry. The resultant data suggest, first, that this approach is viable, even given the existing uncertainties, and that a cooling trend occurred in the Basin of Mexico over the past 1450 yr, a result corroborated by other paleoclimatic data.

Microarrays typically measure expression across genomic space, creating a massive matrix of co-expression that must be mined to extract only the most relevant gene interactions. We describe a graph theoretical approach to extracting co-expressed sets of genes, based on the computation of cliques. Unlike the results of traditional clustering algorithms, cliques are not disjoint and allow genes to be assigned to multiple sets of interacting partners, consistent with biological reality. A graph is created by thresholding the correlation matrix to include only the correlations most likely to signify functional relationships. Cliques computed from the graph correspond to sets of genes for which significant edges are present between all members of the set, representing potential members of common or interacting pathways. Clique membership can be used to infer function about poorly annotated genes, based on the known functions of better-annotated genes with which they share clique membership (i.e., 'guilt-by-association'). We illustrate our method by applying it to microarray data collected from the spleens of mice exposed to low-dose ionizing radiation. Differential analysis is used to identify sets of genes whose interactions are impacted by radiation exposure. The correlation graph is also queried independently of clique to extract edges that are impacted by radiation. We present several examples of multiple gene interactions that are altered by radiation exposure and thus represent potential molecular pathways that mediate the radiation response.

This HSI system is based on state-of-the-art liquid crystal tunable filter technology coupled to an endoscope. The goal of this unique HSI technology being developed is to obtain spatially resolved images of the slight differences in luminescent properties of malignant versus non-malignant tissues. In this report, the development of the instrument is discussed and the capability of the instrument is demonstrated by observing mouse carcinomas in-vivo. It is shown that the instrument successfully distinguishes between normal and malignant mouse skin. It is hoped that the results of this study will lead to advances in the optical diagnosis of cancer in humans.

The complex dynamics of cellular processes demand the integration of methodologies that describe biological systems at the levels of regulation, gene and protein expression, and metabolite production. Genomic microarray analysis of the transcriptome dynamics of midexponential phase cells subjected to 1 mm potassium chromate (K(2)CrO(4)) at exposure time intervals of 5, 30, 60, and 90 min revealed 910 genes that were differentially expressed at one or more time points. Strongly induced genes included those encoding components of a TonB1 iron transport system (tonB1-exbB1-exbD1), hemin ATP-binding cassette transporters (hmuTUV), TonB-dependent receptors as well as sulfate transporters (cysP, cysW-2, and cysA-2), and enzymes involved in assimilative sulfur metabolism (cysC, cysN, cysD, cysH, cysI, and cysJ). Transcript levels for genes with annotated functions in DNA repair (lexA, recX, recA, recN, dinP, and umuD), cellular detoxification (so1756, so3585, and so3586), and two-component signal transduction systems (so2426) were also significantly up-regulated (p < 0.05) in Cr(VI)-exposed cells relative to untreated cells. By contrast, genes with functions linked to energy metabolism, particularly electron transport (e.g. so0902-03-04, mtrA, omcA, and omcB), showed dramatic temporal alterations in expression with the majority exhibiting repression. Differential proteomics based on multidimensional HPLC-MS/MS was used to complement the transcriptome data, resulting in comparable induction and repression patterns for a subset of corresponding proteins. In total, expression of 2,370 proteins were confidently verified with 624 (26%) of these annotated as hypothetical or conserved hypothetical proteins. The initial response of S. oneidensis to chromate shock appears to require a combination of different regulatory networks that involve genes with annotated functions in oxidative stress protection, detoxification, protein stress protection, iron and sulfur acquisition, and SOS-controlled DNA repair mechanisms.

Physical and chemical properties of natural aquifer systems, such as reactive iron-oxide surface area and hydraulic conductivity, are often highly heterogeneous in complex ways that can exert significant control on transport, natural attenuation, and active remediation processes. Typically, however, few data on the detailed distribution of these properties are available for incorporation into predictive models. In this study, we integrate field-scale geophysical, hydrologic, and geochemical data from a well-characterized site with the results of laboratory batch-reaction studies to formulate two-dimensional numerical models of reactive transport in a heterogeneous granular aquifer. The models incorporate several levels of coupling, including effects of ferrous iron sorption onto (and associated reduction of reactive surface area of) ferric iron surfaces, microbial growth and transport dynamics, and cross-correlation between hydraulic conductivity and initial ferric iron surface area. These models are then used to evaluate the impacts of physical and chemical heterogeneity on transport of trace levels of uranium under natural conditions, as well as the effectiveness of uranium reduction and immobilization upon introduction of a soluble electron donor (a potential biostimulation remedial strategy).

Fluid samples obtained from the injection and observation wells before, during and after CO (sub 2) injection show a Na-Ca-Cl type brine with 93,000 mg/L TDS and near saturation of CH (sub 4) at reservoir conditions. As injected CO (sub 2) gas reached the observation well, results showed sharp drops in pH (6.5 to 5.7), pronounced increases in alkalinity (100 to 3000 mg/L as HCO (sub 3) ) and Fe (30 to 1100 mg/L), and significant shifts in the isotopic compositions of H (sub 2) O and DIC. Geochemical modeling indicates that brine pH would have dropped lower, but for buffering by dissolution of calcite and Fe oxyhydroxides. Post-injection results show the brine gradually returning to its pre-injection composition.

A process is described by which laboratory bioassays, computational fluid dynamics models, and field studies can be integrated to evaluate the significance of fluid shear stresses that occur in a turbine. Areas containing potentially lethal shear stresses were identified near the stay vanes and wicket gates, runner, and in the draft tube of a large Kaplan turbine. However, under typical operating conditions, computational models estimated that these dangerous areas comprise less than 2% of the flow path through the modeled turbine. The predicted volumes of the damaging shear stress zones did not correlate well with observed fish mortality at a field installation of this turbine, which ranged from less than 1% to nearly 12%. Possible reasons for the poor correlation are discussed. Computational modeling is necessary to develop an understanding of the role of particular fish injury mechanisms, to compare their effects with those of other sources of injury, and to minimize the trial and error previously needed to mitigate those effects. The process we describe is being used to modify the design of hydroelectric turbines to improve fish passage survival.

The high-nickel, low-manganese, low-copper VVER-1000 weld and forging exhibited lower than predicted levels of embrittlement during neutron irradiation. The Palisades weld exhibits a Delta T41 J of 102 DGC which was significantly lower than the value of 154 DGC predicted by Reg. Guide 1.99 Rev. 2. Atom probe tomography revealed nickel-, manganese-, and silicon-enriched precipitates in both the VVER-1000 base and weld materials after neutron irradiation. A high number density of copper-, nickel-, manganese-, silicon- and phosphorus-enriched precipitates were observed in the Palisades weld after neutron irradiation. Atom probe tomography also revealed high levels of phosphorus segregation to the dislocations in all three materials.

This paper defines and explains the deformation modes in 316 and 316LN stainless steels and suggests the procedures to produce a deformation mode map. A variety of microstructural features such as dislocation tangles and pileups, dislocation channels, stacking faults, and twins have been observed in the deformation of irradiated stainless steels. Attempts were also made to depict macroscopic phenomena such as uniform deformation, necking, and final fracture in the map. Stress criteria for twinning, channeling, plastic instability, and final failure were proposed and used to establish boundaries between the different deformation modes. Two alternative strain localization mechanisms, twinning and channeling, shared the high-dose region. The region of stable plastic deformation became narrower as dose increased, while the elastic deformation region was enlarged with dose and the unstable deformation region was kept unchanged over the whole dose range.

We considered three He defect configurations: two He atoms in an interstitial position and two and three He atoms located in one vacancy. To study He-vacancy clusters containing more He atoms, we used a multi-scale approach and constructed an empirical potential fitted to both formation and relaxation energies of a single He defect and small He clusters obtained from the first principles calculations. The potential consists of a repulsive pair-interaction part and a many-body attractive term describing the cohesion. The potential was used to study stability of He-vacancy clusters at zero temperature. The binding energy of a He atom to a He-cluster varies from 1.3 eV to 1.9 eV depending on the cluster size. When more than six He atoms are placed into a vacancy an Fe self-interstitial atom (SIA) is produced. The SIA binding energy to a He-di-vacancy cluster decreases from 5.0 eV to 0.7 eV as the number of He atoms increases. The results obtained are consistent with experimental observations of helium desorption reported in the literature.

Excessive crystallographic anisotropy leads to unwanted anisotropic dimensional changes during irradiation that can cause the TRISO coatings to fail. Early optical methods were developed in the 60s and 70s to measure this anisotropy by taking advantage of the large optical anisotropy of graphite. Since that time, there have been significant improvements in both the theoretical understanding and experimental techniques in the understanding of optical anisotropy. Here we discuss a new method, based on the two-modulator generalized ellipsometer (2-MGE) to measure the optical anisotropy. This technique has been demonstrated to measure the optical diattenuation to an accuracy from -0.001 to -0.005 and the preferred direction of the crystallites to an accuracy of better than -2DG with a spatial resolution of better than 5 is a subset of m. Diattenuation 'pictures' of the nuclear fuel cross-sections reveal that the inner pyrocarbon layer (IPyC) is far from uniform both in the degree of diattenuation and in the direction of the principal axis. The 2-MGE technique is faster, more accurate, and collects considerably more data than previous optical anisotropy measurements of TRISO fuel particles.

To further investigate the genomic diversity among this group and to help characterize lineages of the plague organism that have no sequenced members, we present here the genomes of two isolates of the "classical" antiqua biovar, strains Antiqua and Nepal516. The genomes of Antiqua and Nepal516 are 4.7 Mb and 4.5 Mb and encode 4,138 and 3,956 open reading frames, respectively. Though both strains belong to one of the three classical biovars, they represent separate lineages defined by recent phylogenetic studies. We compare all five currently sequenced Y. pestis genomes and the corresponding features in Yersinia pseudotuberculosis. There are strain-specific rearrangements, insertions, deletions, single nucleotide polymorphisms, and a unique distribution of insertion sequences. We found 453 single nucleotide polymorphisms in protein-coding regions, which were used to assess the evolutionary relationships of these Y. pestis strains. Gene reduction analysis revealed that the gene deletion processes are under selective pressure, and many of the inactivations are probably related to the organism's interaction with its host environment. The results presented here clearly demonstrate the differences between the two biovar antiqua lineages and support the notion that grouping Y. pestis strains based strictly on the classical definition of biovars (predicated upon two biochemical assays) does not accurately reflect the phylogenetic relationships within this species. A comparison of four virulent Y. pestis strains with the human-avirulent strain 91001 provides further insight into the genetic basis of virulence to humans.

Irradiated specimens were characterized using transmission electron microscopy (TEM). Visible defect clusters were not detectable by TEM for doses below 0.001 dpa. Both the density and average size of the dislocation loops increased with increasing dose level. Spatially heterogeneous rafts of dislocation loops lying predominantly on {1 1 1} habit planes were visible for doses above 0.2 dpa. A high density of small cavities (number density >1024 m-3, 1 nm diameter) was detected following irradiation to 0.79 dpa. The neutron irradiation led to an increase in the yield stress and a decrease in the uniform elongation as a function of increasing dose. Examination of specimens after tensile deformation revealed localized deformation in the form of cleared dislocation channels. Relatively few channels were formed in the uniform elongation region of the gage section. Dislocation channels on multiple slip systems were observed in the deformation region near the fracture surface, presumably due to the multiaxial stress state produced during necking and fracture of the tensile specimen.

Three different destruction processes were observed: a triangular Frank loop remained after the collapse (Type 1), the whole SFT was incorporated into a gliding dislocation as multiple super jog segments (Type 2), and an apex portion of the original SFT remained as a smaller SFT while the base portion was annihilated (Type 3). The remnants of Type 1 and 2 destruction processes were similar to those of previous models proposed by Kimura, indicating that these processes are based on dislocation reactions as assumed in Kimura models. On contrary, the Type 3 process, which was entirely different from Kimura models, is occasionally accompanied by vacancy migration.

The alloy that was neutron irradiated to a fluence of 5 X 1023 n m-2 exhibited a high number density of Cu-enriched precipitates and a shift in the ductile-to-brittle transformation temperature of Delta T41J = 96 DGC. Annealing for 168 h at 460 DGC coarsened these Cu-enriched precipitates and recovered the embrittlement. The material that was re-irradiated to a total fluence 1.7 X 1023 n m-2 also exhibited a high number density of Cu-enriched precipitates and a Delta T41J shift of 56 DGC. Annealing the re-irradiated material for 168 h at 460 DGC coarsened these precipitates and recovered the embrittlement.

Neutron irradiation in the range of 65-100 DGC up to 1 displacement per atom (dpa) induced a high number density of black spots, stacking fault tetrahedra (SFT) and Frank loops, which resulted in irradiation-induced hardening. Deformation of irradiated fcc materials induced various microstructures, such as dislocation channels, stacking faults, and twins. In the 316SS irradiated to 0.1-0.8 dpa, the deformation microstructure consisted of a mixture of dislocation bands, tangles, twins, dislocation channels, and also martensite phase. Deformation-induced martensite transformation tends to occur with dislocation channeling, suggesting that localized deformation could lead to transformation of austenite to martensite at a high stress level. At higher irradiation doses (0.1-1 dpa), dislocation channeling became the dominant deformation mode in fcc materials, and is coincident with prompt plastic instability at yield. The channel width seems to be wider when the angle between tensile direction and dislocation slip direction is close to 45DG. Furthermore, the correlation between channel width and resolved shear stress appears to be material dependent, with copper having the greatest slope and 316SS the smallest.

The microstructural stability of MA/ODS Fe-14 wt% Cr-3% W-0.4% Ti-0.3% Y2O3 ferritic alloys was investigated by atom probe tomography. Atom probe tomography revealed that these MA/ODS 14YWT ferritic alloys contain a high number density of nanometer scale titanium-, yttrium- and oxygen-enriched nanoclusters in the as-extruded condition. These nanoclusters were found to be extremely resistant to coarsening at temperatures of at least 1000 DGC.

Scanning electron microscope observations coupled with fractal analysis revealed the multi-scale nature of the textured coating. Both stylus based profilometric measurements and fractal analysis indicated non-linear nature of the relationship between laser processing speed at constant pulse frequency (10 kHz) and roughness of the textured coating. The textured coatings produced with all the three processing speeds (40, 160, 290 cm/min) were fractal over certain length scales. Processing at 40 cm/min resulted in structures that are fractal across a large number of length scales where as higher processing speeds resulted in fractality over fewer length scales. The processing speed influenced the zirconia content in the coating and the phase transformation within Ti-matrix of the coating. Within the coating, while zirconia content decreased the amount of retained beta -Ti increased with increase in processing speed. Such physical and chemical transformations are desired in a titanium bio-implant for effective contact with protein, cells and tissues at various length scales and its effective chemical performance in bio-environment.

Complete genome sequencing revealed that the E. canis genome consists of a single circular chromosome of 1,315,030 bp predicted to encode 925 proteins, 40 stable RNA species, 17 putative pseudogenes, and a substantial proportion of noncoding sequence (27%). Interesting genome features include a large set of proteins with transmembrane helices and/or signal sequences and a unique serine-threonine bias associated with the potential for O glycosylation that was prominent in proteins associated with pathogen-host interactions. Furthermore, two paralogous protein families associated with immune evasion were identified, one of which contains poly(G-C) tracts, suggesting that they may play a role in phase variation and facilitation of persistent infections. Genes associated with pathogen-host interactions were identified, including a small group encoding proteins (n = 12) with tandem repeats and another group encoding proteins with eukaryote-like ankyrin domains (n = 7).

More than 700 genes were found to be significantly affected (P less than or equal to 0.05) upon cold shock challenge, especially at 8 degree C. The temporal gene expression patterns of the classical cold shock genes varied, and only some of them, most notably so1648 and so2787, were differentially regulated in response to a temperature downshift. The global response of S. oneidensis to cold shock was also characterized by the up-regulation of genes encoding membrane proteins, DNA metabolism and translation apparatus components, metabolic proteins, regulatory proteins, and hypothetical proteins. Most of the metabolic proteins affected are involved in catalytic processes that generate NADH or NADPH. Mutational analyses confirmed that the small cold shock proteins, So1648 and So2787, are involved in the cold shock response of S. oneidensis. The analyses also indicated that So1648 may function only at very low temperatures.

Increased salinity is an important and frequent fluctuation faced by D. vulgaris in its natural habitat. In liquid culture, exposure to excess salt resulted in striking elongation of D. vulgaris cells. Using data from transcriptomics, proteomics, metabolite assays, phospholipid fatty acid profiling, and electron microscopy, we used a systems approach to explore the effects of excess NaCl on D. vulgaris. In this study we demonstrated that import of osmoprotectants, such as glycine betaine and ectoine, is the primary mechanism used by D. vulgaris to counter hyperionic stress. Several efflux systems were also highly up-regulated, as was the ATP synthesis pathway. Increases in the levels of both RNA and DNA helicases suggested that salt stress affected the stability of nucleic acid base pairing. An overall increase in the level of branched fatty acids indicated that there were changes in cell wall fluidity. The immediate response to salt stress included up-regulation of chemotaxis genes, although flagellar biosynthesis was down-regulated. Other down-regulated systems included lactate uptake permeases and ABC transport systems. The results of an extensive NaCl stress analysis were compared with microarray data from a KCl stress analysis, and unlike many other bacteria, D. vulgaris responded similarly to the two stresses. Integration of data from multiple methods allowed us to develop a conceptual model for the salt stress response in D. vulgaris that can be compared to those in other microorganisms.

AN - 67880009; 16621779 AB - Acute exposure guideline levels (AEGLs) have been developed for the chemical warfare agents GB, GA, GD, GF, VX, and sulfur mustard. These AEGLs were approved by the National Advisory Committee for Acute Exposure Guideline Levels for Hazardous Substances after Federal Register publication and comment, and judged as scientifically valid by the National Research Council Committee on Toxicology Subcommittee on AEGLs. AEGLs represent general public exposure limits for durations ranging from 10 min to 8 h, and for three levels of severity (AEGL-1, AEGL-2, AEGL-3). Mild effects are possible at concentrations greater than AEGL-1, while life-threatening effects are expected at concentrations greater than AEGL-3. AEGLs can be applied to various civilian and national defense purposes, including evacuation and shelter-in-place protocols, reentry levels, protective clothing specifications, and analytical monitoring requirements. This report documents development and derivation of AEGL values for six key chemical warfare agents, and makes recommendations for their application to various potential exposure scenarios.

7425330 AB - We encapsulated radioisotope-spiked soil within a water- permeable polyacrylamide matrix cast in a small cylindrical geometry ( similar to 5 cm3) to measure the persistence of immobilized soil contaminants. As a proof-of-principle, soils contained within these permeable environmental leaching capsules (PELCAPs) were labeled with either 85Sr or 134Cs and were leached in both laboratory tests and continuously it in situ with ground and stream waters at two field sites on the Oak Ridge Reservation. Groups of PELCAPs were retrieved, assayed nondestructively for radioisotopes via gamma spectroscopy, and then replaced in ground and surface water over a six month period. PELCAPs that contained no soil readily and quantitatively leached either 85Sr or 134Cs into laboratory extractants or ground or surface water with effective diffusion coefficients (D_eff) of (1.14 pm 0.06) and (4.8 pm 0.2) times 10-6 cm2/s, respectively. These D_eff values are within an order-of-magnitude of those reported for aqueous solutions at 25degC. PELCAPs containing thermally- treated soil quantitatively retained both isotopes in the field tests and in laboratory sequential extractions. PELCAPs containing untreated soil readily leached >90% of 85Sr but <1% of 134Cs during field leaching at both sites. Soils were quantitatively retained in the PELCAP polymer matrix and maintained their cation exchange capacities during the exposure period. Permeable polymer encapsulation methods, such as PELCAPs, offer the potential capability to conveniently test large numbers of soils and soil treatments for contaminant release and uptake under actual field environmental conditions.

Only 4% of the native longleaf pine (Pinus palustris) forest remains intact. Besides the loss of species, habitats, and ecosystem services associated with longleaf pine forests, the environmental concerns of the region include air, water, and noise pollution. The mix of federal and private ownership in this region leads to complicated land-management issues that will likely become even more difficult as the city of Columbus continues its projected growth along the northern border of Fort Benning. To understand how anthropogenic developments affect the environment, we are developing a Regional Simulator (RSim) to project future developments and their impacts on environmental conditions. Using RSim, we can identify the potential effects of growth on noise and air pollution, water-borne nutrients, and habitats for focal species. Noise impacts are already large in the areas of current and projected urban growth for the region. This knowledge of potential futures allows options for environmental protection to be considered. A key lesson from this analysis is that regional simulation models are a cost-effective way to assess the long-term environmental implications of anthropogenic growth and development.

The site is being remediated as one of the top cleanup prioritization for the Oak Ridge Accelerated Remediation endeavor. Site landlords, Bechtel Jacobs Co., LLC (BJC) are installing a minimal RCRA cap with the primary objective of controlling the infiltration of storm water into the hundreds of unconfined waste trenches containing radioactive and organic waste. The site now offers a unique scientific opportunity to track the kinetic evolution of post- cap processes influencing contaminant migration and immobilization, because we have many years of pre-cap coupled processes information and knowledge. Since the cap is certain to disrupt the near steady-state contaminant discharge profiles that have existed for many years from the site, we have been quantifying the influence of post-cap hydrological, geochemical, and microbial processes on contaminant discharge as a function of scale and time in an effort to assess local-scale cap influences versus regional scale groundwater flow influences on contaminant discharge. We have been allowed to maintain numerous groundwater monitoring wells at a field site and these have a rich historical data set with regard to hydrology, geochemistry, microbiology, and contaminant flux. Our objectives are to investigate cap induced changes in (1) groundwater and surface hydrology and contaminant flux, (2) geochemistry and contaminant speciation, and (3) microbial community structure and organic contaminant degradation and inorganic contaminant immobilization. Our approach monitors coupled processes during base-flow and during storm events in both the groundwater and surface water discharge from the site and the surrounding watershed. Pre- and post-cap data will than be modeled with a multiprocess, multicomponent, transport model which is linked to pre- and post-cap surface water hydrograph analysis from the site and the surrounding watershed. Our goal is to provide an improved fundamental understanding of the long-term fate and transport of contaminants and an improved ability to predict system response to remedial actions. The experimental and numerical results from this investigation will provide knowledge and information in previously unexplored areas of cap performance with regard to coupled hydrology, geochemistry, microbiology, and contaminant flux in humid regimes. The products will support DOEs mission of long-term stewardship of contaminated environments and be transferable to other site where similar remediation exists or is planned.

Multiple displacement amplification (MDA) using h29 DNA polymerase was used to amplify whole genomes from environmental, contaminated, subsurface sediments. By first amplifying the genomic DNA (gDNA), biodiversity analysis and gDNA library construction of microbes found in contaminated soils were made possible. The MDA method was validated by analyzing amplified genome coverage from approximately five Escherichia coli cells, resulting in 99.2% genome coverage. The method was further validated by confirming overall representative species coverage and also an amplification bias when amplifying from a mix of eight known bacterial strains. We extracted DNA from samples with extremely low cell densities from a U.S. Department of Energy contaminated site. After amplification, small-subunit rRNA analysis revealed relatively even distribution of species across several major phyla. Clone libraries were constructed from the amplified gDNA, and a small subset of clones was used for shotgun sequencing. BLAST analysis of the library clone sequences showed that 64.9% of the sequences had significant similarities to known proteins, and "clusters of orthologous groups" (COG) analysis revealed that more than half of the sequences from each library contained sequence similarity to known proteins. The libraries can be readily screened for native genes or any target of interest. Whole-genome amplification of metagenomic DNA from very minute microbial sources, while introducing an amplification bias, will allow access to genomic information that was not previously accessible.

Strain PV-4 AN - 19957038; 6812817 AB - A marine psychrotolerant, dissimilatory Fe(III)-reducing bacterium, Shewanella sp. strain PV-4, from the microbial mat at a hydrothermal vent of Loihi Seamount in the Pacific Ocean has been further characterized, with emphases on metal reduction and iron biomineralization. The strain is able to reduce metals such as Fe(III), Co(III), Cr(VI), Mn(IV), and U(VI) as electron acceptors while using lactate, formate, pyruvate, or hydrogen as an electron donor. Growth during iron reduction occurred over the pH range of 7.0 to 8.9, a sodium chloride range of 0.05 to 5%, and a temperature range of 0 to 37 degree C, with an optimum growth temperature of 18 degree C. Unlike mesophilic dissimilatory Fe(III)-reducing bacteria, which produce mostly superparamagnetic magnetite (35 nm) at temperatures from 18 to 37 degree C. The genome size of this strain is about 4.5 Mb. Strain PV-4 is sensitive to a variety of commonly used antibiotics except ampicillin and can acquire exogenous DNA (plasmid pCM157) through conjugation.

The mesophyll-feeding scale insect (Matsucoccus acalyptus) found near Sunset Crater National Monument in northern Arizona, USA significantly increases pinon (Pinus edulis) needle litter nitrogen (N) and phosphorus (P) concentrations by 50%, as well as litter inputs to soil by 21%. Because increases in needle litter quality and quantity of this magnitude should affect the microbial communities responsible for decomposition, we tested the hypothesis that insect herbivory causes a shift in soil microbial and litter microarthropod function. Four major findings result from this research: (1) Despite increases in needle inputs due to herbivory, soil carbon (C) was 56% lower beneath scale-susceptible trees than beneath resistant trees; however, soil moisture, N, and pH were similar among treatments. (2) Microbial biomass was 80% lower in soils beneath scale-susceptible trees when compared to resistant trees in the dry season, while microbial enzyme activities were lower beneath susceptible trees in the wet season. (3) Bacterial community-level physiological profiles differed significantly between susceptible and resistant trees during the dry season but not during the wet season. (4) There was a 40% increase in Oribatida and 23% increase in Prostigmata in susceptible needle litter relative to resistant litter. Despite these changes, the magnitude of microbial biomass, activity, and community structure response to herbivory was lower than expected and appears to take a long time to develop. These results suggest that herbivores impact soils in subtle, but important ways; we suggest that while litter chemistry may strongly mediate soil fertility and microbial communities in mesic ecosystems, the influence is lower than expected in this primary succession xeric ecosystem where season mediates differences in microbial populations. Understanding how insect herbivores alter the distribution of susceptible and resistant trees and their associated decomposer communities in arid environments may lead to better prediction of how these ecosystems respond to climatic change.

7544893 AB - Because of their unique physical and chemical properties, vertically aligned carbon nanofibres (VACNFs) show promise in improving current analytical measurement techniques. Chemical functionalization schemes will be necessary to fully realize this promise. Functionalization of the VACNFs with biomolecules or other species can impart specific chemical or physical properties. We report on two methods for immobilizing biomolecules on the surface of VACNFs. One attachment scheme makes use of a class of heterocycl40 xromatic dye compounds to specifically adsorb onto VACNFs. The second scheme involves covalently coupling biomolecules through cross-linking to carboxylic acid sites on the sidewalls of the carbon nanofibres. The observed adsorption and covalent coupling properties are consistent with the physical structure and chemical characteristics of the VACNFs.

AN - 67824884; 16537572 AB - The mammalian Nell1 gene encodes a protein kinase C-beta1 (PKC-beta1) binding protein that belongs to a new class of cell-signaling molecules controlling cell growth and differentiation. Over-expression of Nell1 in the developing cranial sutures in both human and mouse induces craniosynostosis, the premature fusion of the growing cranial bone fronts. Here, we report the generation, positional cloning and characterization of Nell1(6R), a recessive, neonatal-lethal point mutation in the mouse Nell1 gene, induced by N-ethyl-N-nitrosourea. Nell1(6R) has a T-->A base change that converts a codon for cysteine into a premature stop codon [Cys(502)Ter], resulting in severe truncation of the predicted protein product and marked reduction in steady-state levels of the transcript. In addition to the expected alteration of cranial morphology, Nell1(6R) mutants manifest skeletal defects in the vertebral column and ribcage, revealing a hitherto undefined role for Nell1 in signal transduction in endochondral ossification. Real-time quantitative reverse transcription-PCR assays of 219 genes showed an association between the loss of Nell1 function and reduced expression of genes for extracellular matrix (ECM) proteins critical for chondrogenesis and osteogenesis. Several affected genes are involved in the human cartilage disorder Ehlers-Danlos Syndrome and other disorders associated with spinal curvature anomalies.

AN - 68006947; 16600046 AB - BACKGROUNDShewanella oneidensis MR-1 is a facultative, gram-negative bacterium capable of coupling the oxidation of organic carbon to a wide range of electron acceptors such as oxygen, nitrate and metals, and has potential for bioremediation of heavy metal contaminated sites. The complete 5-Mb genome of S. oneidensis MR-1 was sequenced and standard sequence-comparison methods revealed approximately 42% of the MR-1 genome encodes proteins of unknown function. Defining the functions of hypothetical proteins is a great challenge and may need a systems approach. In this study, by using integrated approaches including whole genomic microarray and proteomics, we examined knockout effects of the gene encoding SO1377 (gi24372955), a member of the conserved, hypothetical, bacterial protein family COG2268 (Clusters of Orthologous Group) in bacterium Shewanella oneidensis MR-1, under various physiological conditions.RESULTSCompared with the wild-type strain, growth assays showed that the deletion mutant had a decreased growth rate when cultured aerobically, but not affected under anaerobic conditions. Whole-genome expression (RNA and protein) profiles revealed numerous gene and protein expression changes relative to the wild-type control, including some involved in iron metabolism, oxidative damage protection and respiratory electron transfer, e. g. complex IV of the respiration chain. Although total intracellular iron levels remained unchanged, whole-cell electron paramagnetic resonance (EPR) demonstrated that the level of free iron in mutant cells was 3 times less than that of the wild-type strain. Siderophore excretion in the mutant also decreased in iron-depleted medium. The mutant was more sensitive to hydrogen peroxide and gave rise to 100 times more colonies resistant to gentamicin or kanamycin.CONCLUSIONOur results showed that the knock-out of SO1377 gene had pleiotropic effects and suggested that SO1377 may play a role in iron homeostasis and oxidative damage protection in S. oneidensis MR-1.

AN - 68587005; 16803652 AB - A new analytical procedure was developed for the quantitation of nonsmoker salivary cotinine. Small volumes of saliva were diluted with water, fortified with cotinine-d3 (internal standard), then passed through small extraction columns. The analyte and internal standard were eluted with 0.1% (v/v) acetic acid/acetonitrile. Aliquots of each extract were analyzed directly, without chromatographic separation, using chip-based (NanoMate) nanospray tandem mass spectrometry. The calculated detection limit was 0.49 ng cotinine/mL saliva. This method was used to quantify salivary cotinine collected from nonsmoking human subjects living in one of three environmental tobacco smoke (ETS) exposure categories or "cells": 1. smoking home/smoking workplace; 2. smoking home/nonsmoking workplace; and 3. nonsmoking home/smoking workplace. Samples were collected during five sequential days, including Saturday, as part of a larger study to evaluate potential variability in exposure to ETS. Salivary cotinine measurements were made for the purpose of excluding misclassified smokers and for comparison with known levels of exposure to airborne nicotine in each exposure category. The concentrations observed were consistent with those reported from other large studies reported elsewhere. A non-parametric statistical test was applied to the data within each cell. No statistically significant differences were found between the mean cotinine concentrations collected on a weekday as compared to those collected on a weekend day. When the non-parametric test was applied to the three cells, a statistically significant difference was observed between cell 1 compared to cells 2 and 3. The salivary cotinine concentrations were thus statistically invariant over a five-day exposure period, and they were greatest under the conditions of smoking home and smoking workplace.

These authors however, failed to refer to an earlier study of Ridley et al.,1997 (Environ.Sci.Technol. 31, 1922-1925) in which it was shown that the release of Al (super 3+) from gibbsite under the specified conditions was approximately 10 X faster in the sulphate medium than in the chloride solution, and appeared to be controlled by a zero-order rate-determining reaction in batch experiments at far-from-equilibrium conditions.Thus the fact that sulphate greatly enhances the dissolution rate of gibbsite under these conditions is not a new finding but had previously been reported.

This approach requires only accurate equations of state (EOS) for pure isotopic end-members (H (sub 2) O and D (sub 2) O), which are available in the literature. The effect of pressure or density on the RIPFR of water was calculated relative to that of ideal-gas water at infinitely low pressure for the temperature range from 0 to 527 degrees C. For gaseous and low-pressure (ca. 20 MPa) supercritical phases, the RIPFR of water decreases (0.5-6 ppm) with increasing pressure (or density) to 100 MPa. This rather unique phenomenon is ascribed to the inverse molar volume isotope effects (MVIE) of liquid and high-density supercritical waters, V(D (sub 2) O) > V(H (sub 2) O), while other substances including minerals show the normal MVIE. These theoretical predictions were experimentally confirmed by Horita et al. [Horita, J., Cole, D. R., Polyakov, V. B., Driesner, T., 2002. Experimental and theoretical study of pressure effects on hydrogen isotope fractionation in the system brucite-water at elevated temperatures. Geochim. Cosmochim. Acta 66, 3769-3788.] for the system brucite-water. Although the P-T ranges for the EOS of normal and heavy waters are rather limited, our modeling indicates that the RIPFR of water continues to decrease with pressure above 100 MPa. The method developed here can be applied to any other geologic fluids, if accurate EOS for their isotopic end-members is available. These results have important implications for the interpretation of high-pressure isotopic partitioning in the Earth, the outer planets, and their moons.

Therefore, we have developed a model that builds on extensive data that are available from public lands and extends them to surrounding private lands. This model is applied for a five-county region in Georgia to predict habitats for the gopher tortoise (Gopherus polyphemus), based on analysis of documented locations of gopher tortoise burrows at the Fort Benning military installation in west central Georgia. Burrow associations with land cover, soil, topography and water observed within the military installation were analyzed with binary logistic regression. This analysis helped generate a probability map for the occurrence of gopher tortoise burrows in the five-county region surrounding Fort Benning. Ground visits were made to test the accuracy of the model in predicting gopher tortoise habitat. The results showed that information on land cover, soils, and distances to streams and roads can be used to predict gopher tortoise burrows. This approach can be used to better understand and effectively carry out gopher tortoise habitat restoration and preservation activities.

SSU rRNA cloned sequences from groundwater samples that represent different bacterial divisions were sequenced multiple times with the same sequencing primer. From comparison of sequence alignments with unedited data, confidence intervals were obtained from both a 'double binomial' model of sequence comparison and by non-parametric methods. The results indicated that similarity values below 0.9946 are likely derived from dissimilar sequences at a confidence level of 0.95, and not sequencing errors. The results confirmed that screening by direct sequence determination could be reliably used to differentiate at the species level. However, given sequencing errors comparable to those seen in this study, sequences with similarities above 0.9946 should be treated as the same sequence if a 95% confidence is desired.

In this paper, the first spectroscopic results for microcantilevers coated with Bacillus anthracis (BA) are presented. These results, for B. anthracis from 2.5 to 14.5 mu m, are compared with results from microcantilevers coated with Bacillus cereus (BC) and standard spectroscopic absorption data. The results demonstrate strong correlation between the deflection measurements and the reference spectroscopic absorption peaks. An advantage of this microcantilever-based method over traditional spectroscopy is that much smaller amounts of material (nanogram quantities) can be detected in comparison with the milligram amounts needed for standard methods. Another advantage is that the complete system can be relatively small without sacrificing spectral resolution.

6736717 AB - Much of modern condensed matter physics is understood in terms of elementary excitations, or quasiparticles-fundamental quanta of energy and momentum. Various strongly interacting atomic systems are successfully treated as a collection of quasiparticles with weak or no interactions. However, there are interesting limitations to this description: in some systems the very existence of quasiparticles cannot be taken for granted. Like unstable elementary particles, quasiparticles cannot survive beyond a threshold where certain decay channels become allowed by conservation laws; their spectrum terminates at this threshold. Such quasiparticle breakdown was first predicted for an exotic state of matter-super-fluid super(4)He at temperatures close to absolute zero, a quantum Bose liquid where zero-point atomic motion precludes crystallization. Here we show, using neutron scattering, that quasiparticle breakdown can also occur in a quantum magnet and, by implication, in other systems with Bose quasiparticles. We have measured spin excitations in a two-dimensional quantum magnet, piperazinium hexachlorodicuprate (PHCC), in which spin-1/2 copper ions form a non-magnetic quantum spin liquid, and find remarkable similarities with excitations in superfluid super(4)He. We observe a threshold momentum beyond which the quasiparticle peak merges with the two-quasiparticle continuum. It then acquires a finite energy width and becomes indistinguishable from a leading-edge singularity, so that excited states are no longer quasiparticles but occupy a wide band of energy. Our findings have important ramifications for understanding excitations with gapped spectra in many condensed matter systems, ranging from band insulators to high-transition-temperature superconductors.

AN - 67644016; 16466381 AB - The impact of legacy nuclear waste on the compositional diversity and distribution of sulfate-reducing bacteria in a heavily contaminated subsurface aquifer was examined. dsrAB clone libraries were constructed and restriction fragment length polymorphism (RFLP) analysis used to evaluate genetic variation between sampling wells. Principal component analysis identified nickel, nitrate, technetium, and organic carbon as the primary variables contributing to well-to-well geochemical variability, although comparative sequence analysis showed the sulfate-reducing bacteria community structure to be consistent throughout contaminated and uncontaminated regions of the aquifer. Only 3% of recovered dsrAB gene sequences showed apparent membership to the Deltaproteobacteria. The remainder of recovered sequences may represent novel, deep-branching lineages that, to our knowledge, do not presently contain any cultivated members; although corresponding phylotypes have recently been reported from several different marine ecosystems. These findings imply resiliency and adaptability of sulfate-reducing bacteria to extremes in environmental conditions, although the possibility for horizontal transfer of dsrAB is also discussed.

The Oak Ridge soil under investigation is a saprolite sequence of interbedded weathered shale and limestone obtained at the capillary fringe with a pH near 7.6. Experiments were conducted on unaltered soils under anaerobic and aerobic conditions using both batch and column systems. Soils were biostimulated using 25 mM ethanol, lactate, or acetate. Initial Cr(VI) concentrations ranged from 1 to 20 ppm. Results from batch and column studies indicate that significantly more chromium was associated with the solid phase in soils stimulated with lactate compared to both ethanol- and acetate-induced soils. Distribution coefficients calculated from batch data imply an order of magnitude increase in solid phase chromium in lactate-induced soils. Preliminary results from x-ray absorption near edge spectroscopy (XANES) suggest the chromium associated with the solid phase is sparingly soluable Cr(III). Results from batch experiments indicate that direct reduction of chromium by lactate cannot account for the majority of the solid phase chromium. Analyses of column effluents indicate that different microbial populations developed in soils stimulated with different carbon sources. Plate counting revealed differences in both the number and species of cells active within the soils. More detailed analyses will be completed using 16s rRNA technique to identify the major bacterial species present. Future experiments using XANES should indicate if chromium reduction is due to direct metabolism by indigenous bacteria or is indirectly related to the amount of reduced iron in the system.

FRC researchers found that introducing naturally occurring humic substances (organic matter found in soil) can accelerate the chemical reduction and immobilization of these contaminants. At the same time, the researchers demonstrated that co-contaminants in the subsurface, such as nitrate, and elevated concentrations of other chemicals, like calcium, can inhibit the chemical reduction process and can reoxidize uranium, making it more mobile. Extensive work has been conducted to identify the microorganisms present in the harsh FRC subsurface environment (an environment that is acidic and that contains high concentrations of nitrate and metals that tend to be toxic to most microorganisms). Work conducted to date has begun to determine which specific microorganisms can be used to promote the chemical reduction of radionuclides directly or indirectly. This research relies on genomic sequencing; cutting-edge techniques such as the use of functional gene arrays; and such novel devices as "bug traps", coupons that trap microbes below the ground's surface. In addition to investigating naturally occurring microbial communities in the FRC's subsurface, researchers have used novel geophysical, hydraulic, and tracer techniques for characterizing and monitoring subsurface processes and groundwater flow. For example, seismic and resistivity techniques are used to create three-dimensional images of the subsurface geology and of contaminated groundwater plumes. Taken together, FRC research findings have contributed to the DOE Office of Biological and Environmental Research goal of understanding the processes that influence the transport and fate of contaminants, the effectiveness and long-term consequences of extant remediation options, and the development of improved remediation strategies--especially for currently intractable contaminants or conditions.

Empirically determined transition temperatures at high pressure in NaNbO (sub 3) and BaTiO (sub 3) (barium titanate) and modifications made to the HDAC experimental setup at the University of Tennessee, Knoxville are also presented. NaNbO (sub 3) is one in a group of well-studied minerals with perovskite-type structure. It has six known structural transitions between -100 degrees C and 641 degrees C at atmospheric pressure. In this study, the monoclinic to orthorhombic transition occurring at 373 degrees C and 1 atm was found to be most applicable in HDAC studies because it is rapid, reversible and easily identified by an abrupt change in birefringence. At high pressure this transition was found to have a positive Clapeyron slope ( approximately 6.0 MPa/ degrees C) that intersects density isochores of pure water. An evaluation of high-pressure transition temperatures determined in HDAC studies for BaTiO (sub 3) and NaNbO (sub 3) shows that, in contrast to Shen et al. (1996), our data results in more accurate transition temperatures on the heating cycle rather than the cooling cycle of each experiment. This may result from fluid loss reduction techniques, which were implemented in the experimental setup. These modifications include a decrease in gasket diameter, a reduction in the amount of gasket polishing, and heating/cooling of the sample chamber in small ( approximately 300 degrees C) intervals.

Current contaminant distributions in the vadose zone are dependent upon the hydrological and geochemical heterogeneities of the sedimentary deposit, particularly grain size, water content, and mineralogy. The goal of this study is to determine the influence of these sedimentary heterogeneities upon the fate and transport of the contaminants uranium(VI) and CoEDTA. Geochemical reactivity was measured in batch kinetic, isotherm, and miscible displacement experiments. Coupled hydrological and geochemical processes were quantified by the displacement of nonreactive tracers and contaminants through large samples of unsaturated and intact sediments. Mechanisms of U(VI) reaction were found to be influenced by sediment type (siliciclastic or carbonate), surface area, and iron oxide content, while CoEDTA mobility was primarily influenced by Mn-oxide content. Sediment texture and the presence of interbedded fine-grained layers were found to significantly influence the hydrology. This study will highlight findings from the geochemical and hydrological investigations in order to provide an integrated approach to understanding subsurface metal transport at Hanford and elsewhere.

Oil peaking analysis from an optimist's perspective AN - 20381534; 7764703 AB - This study addresses several questions concerning the peaking of conventional oil production from an optimist's perspective. Is the oil peak imminent? What is the range of uncertainty? What are the key determining factors? Will a transition to unconventional oil undermine or strengthen OPEC's influence over world oil markets? These issues are explored using a model combining alternative world energy scenarios with an accounting of resource depletion and a market-based simulation of transition to unconventional oil resources. No political or environmental constraints are allowed to hinder oil production, geological constraints on the rates at which oil can be produced are not represented, and when USGS resource estimates are used, more than the mean estimate of ultimately recoverable resources is assumed to exist. The issue is framed not as a question of 'running out' of conventional oil, but in terms of the timing and rate of transition from conventional to unconventional oil resources. Unconventional oil is chosen because production from Venezuela's heavy-oil fields and Canada's Athabascan oil sands is already underway on a significant scale and unconventional oil is most consistent with the existing infrastructure for producing, refining, distributing and consuming petroleum. However, natural gas or even coal might also prove to be economical sources of liquid hydrocarbon fuels. These results indicate a high probability that production of conventional oil from outside of the Middle East region will peak, or that the rate of increase of production will become highly constrained before 2025. If world consumption of hydrocarbon fuels is to continue growing, massive development of unconventional resources will be required. While there are grounds for pessimism and optimism, it is certainly not too soon for extensive, detailed analysis of transitions to alternative energy sources.

Sequencing and analysis of its genome revealed a single circular chromosome of 3,402,093 bp encoding 3,143 predicted proteins. There were extensive similarities to genes in two alphaproteobacteria, Bradyrhizobium japonicum USDA110 (1,300 genes) and Rhodopseudomonas palustris CGA009 CG (815 genes). Genes encoding pathways for known modes of chemolithotrophic and chemoorganotrophic growth were identified. Genes encoding multiple enzymes involved in anapleurotic reactions centered on C sub(2) to C sub(4) metabolism, including a glyoxylate bypass, were annotated. The inability of N. winogradskyi to grow on C sub(6) molecules is consistent with the genome sequence, which lacks genes for complete Embden-Meyerhof and Entner-Doudoroff pathways, and active uptake of sugars. Two gene copies of the nitrite oxidoreductase, type I ribulose-1,5-bisphosphate carboxylase/oxygenase, cytochrome c oxidase, and gene homologs encoding an aerobic-type carbon monoxide dehydrogenase were present. Similarity of nitrite oxidoreductases to respiratory nitrate reductases was confirmed. Approximately 10% of the N. winogradskyi genome codes for genes involved in transport and secretion, including the presence of transporters for various organic-nitrogen molecules. The N. winogradskyi genome provides new insight into the phylogenetic identity and physiological capabilities of nitrite-oxidizing bacteria. The genome will serve as a model to study the cellular and molecular processes that control nitrite oxidation and its interaction with other nitrogen-cycling processes.

The system consists of a laser, endoscope, AOTF, and two cameras coupled with optics and electronics. Initial results show that the system can delineate normal and malignant mouse tissues real-time. The analysis shows that malignant tissues consistently exhibit less fluorescent intensity in the wavelength band from 440 to 540 nm with a peak intensity of around 490 nm. The analysis also shows key spectroscopic differences between normal and malignant tissues. Further, these results are compared to real-time spectroscopic data and show good correlation.

Given the importance of SRB-mediated reduction for bioremediation of metal ion contaminants, ongoing research on D. vulgaris has been in the direction of elucidating regulatory mechanisms for this organism under a variety of stress conditions. This work presents a global view of this organism's response to elevated growth temperature using whole-cell transcriptomics and proteomics tools. Transcriptional response (1.7-fold change or greater; Z greater than or equal to 1.5) ranged from 1,135 genes at 15 min to 1,463 genes at 120 min for a temperature up-shift of 13 degree C from a growth temperature of 37 degree C for this organism and suggested both direct and indirect modes of heat sensing. Clusters of orthologous group categories that were significantly affected included posttranslational modifications; protein turnover and chaperones (up-regulated); energy production and conversion (down-regulated), nucleotide transport, metabolism (down-regulated), and translation; ribosomal structure; and biogenesis (down-regulated). Analysis of the genome sequence revealed the presence of features of both negative and positive regulation which included the CIRCE element and promoter sequences corresponding to the alternate sigma factors sigma super(32) and sigma super(54). While mechanisms of heat shock control for some genes appeared to coincide with those established for Escherichia coli and Bacillus subtilis, the presence of unique control schemes for several other genes was also evident. Analysis of protein expression levels using differential in-gel electrophoresis suggested good agreement with transcriptional profiles of several heat shock proteins, including DnaK (DVU0811), HtpG (DVU2643), HtrA (DVU1468), and AhpC (DVU2247). The proteomics study also suggested the possibility of posttranslational modifications in the chaperones DnaK, AhpC, GroES (DVU1977), and GroEL (DVU1976) and also several periplasmic ABC transporters.

6644674 AB - Brine spills associated with petroleum extraction can reduce the amount of suitable habitat and increase habitat fragmentation for many terrestrial animals. We conducted a simulation study to quantify the effects of habitat loss and fragmentation on a solitary mammal predator. To provide focus, we adopted biological attributes of the American badger (Taxidea taxus) and environmental attributes of the Tallgrass Prairie Preserve in Oklahoma. We simulated badger activities on landscapes with different degrees of habitat loss and fragmentation using a spatially explicit and individual-based population model. Both habitat loss and fragmentation increased the incidence of habitat- related mortality and decreased the proportion of eligible females that mated, which decreased final population sizes and the likelihood of persistence. Parameter exploration suggested that steep, threshold-like, responses to habitat loss occurred when animals included high-risk habitat in their territories. Badger populations showed a steeper decline with increasing habitat loss on landscapes fragmented by spills than on less fragmented landscapes. Habitat fragmentation made it difficult for badgers to form high-quality territories, and exposed individuals to higher risk while seeking to establish a territory. Our simulations also suggest that an inability to find mates (an Allee effect) becomes increasingly important for landscapes that support a sparse distribution of territories. Thus, the presence of unmated females with territories may foreshadow population decline in solitary species that do not normally tolerate marginal adults.

Previous experiments focused on noise sources or noise propagation through gene networks by measuring noise magnitudes. However, in theoretical analysis, we showed that noise frequency content is determined by the underlying gene circuits, leading to a mapping between gene circuit structure and the noise frequency range. An intriguing prediction from our previous studies was that negative autoregulation shifts noise to higher frequencies where it is more easily filtered out by gene networks-a property that may contribute to the prevalence of autoregulation motifs (for example, found in the regulation of similar to 40% of Escherichia coli genes). Here we measure noise frequency content in growing cultures of E. coli, and verify the link between gene circuit structure and noise spectra by demonstrating the negative autoregulation-mediated spectral shift. We further demonstrate that noise spectral measurements provide mechanistic insights into gene regulation, as perturbations of gene circuit parameters are discernible in the measured noise frequency ranges. These results suggest that noise spectral measurements could facilitate the discovery of novel regulatory relationships.

Efforts to enhance terrestrial organic carbon sequestration have traditionally focused on aboveground biomass and surface soils. An unexplored potential exists in thick lower horizons of widespread, mature soils such as Alfisols, Ultisols, and Oxisols. We present a case study of fate and transport of dissolved organic carbon (DOC) in a highly weathered Ultisol, involving spatial scales from the laboratory to the landscape. Our objectives were to interpret processes observed at various scales and provide an improved understanding of coupled hydrogeochemical mechanisms that control DOC mobility and sequestration in deep subsoils within humid climatic regimes. Our approach is multiscale, using laboratory-scale batch and soil columns (0.2 by 1.0 m), an in situ pedon (2 by 2 by 3 m), a well-instrumented subsurface facility on a subwatershed (0.47 ha), and ephemeral and perennial stream discharge at the landscape scale (38.4 ha). Laboratory-scale experiments confirmed that lower horizons have the propensity to accumulate DOC, but that preferential fracture flow tends to limit sequestration. Intermediate-scale experiments demonstrated the beneficial effects of C diffusion into soil micropores. Field- and landscape-scale studies demonstrated coupled hydrological, geochemical, and microbiological mechanisms that limit DOC sequestration, and their sensitivity to local environmental conditions. Our results suggest a multi-scale approach is necessary to assess the propensity of deep subsoils to sequester organic C in situ. By unraveling fundamental organic C sequestration mechanisms, we improve the conceptual and quantitative understanding needed to predict and alter organic C budgets in soil systems.

The occurrence of two-phase fluid inclusions decreases from shock stage 0 to shock stage 1, while single-phase inclusions increase, likely as a result of re-equilibration. In shock stages 2 and 3, both two-phase and single-phase inclusions decrease with increasing shock stage, indicating that fluid inclusion vesicles are destroyed due to plastic deformation and phase changes in the host minerals. However, quartz clasts entrained in shock stage 4 melts contain both single-phase and two-phase inclusions, demonstrating the rapid quenching of the melt and the heterogeneous nature of impact deformation. Inclusions in naturally shocked polycrystalline samples survive at higher shock pressures than those in single crystal shock experiments. However, fluid inclusions in both experimental and natural samples follow a similar trend in re-equilibration at low to moderate shock pressures leading to destruction of inclusion vesicles in higher shock stages. This suggests that shock processing may lead to the destruction of fluid inclusions in many planetary materials and likely contributed to shock devolatilization of early planetesimals.

Gamma distributions are used as parametric models of the transfer functions. Apparent parameters of classical transport models may be estimated from those of the gamma distributions by matching temporal moments. We demonstrate the method by application to measured data taken at a field experiment on bioremediation conducted in a multiple-well system in Oak Ridge, TN. Breakthrough curves (BTCs) of a conservative tracer (bromide) and a reactive compound (ethanol) are measured at multi-level sampling (MLS) wells and in extraction wells. The BTCs of both compounds are jointly analyzed to estimate the first-order degradation rate of ethanol. To quantify the tracer loss, we compare the approaches of using a scaling factor and a first-order decay term. Results show that by including a scaling factor both gamma distributions and inverse-Gaussian distributions (transfer functions according to the advection-dispersion equation) are suitable to approximate the transfer functions and estimate the reactive rate coefficients for both MLS and extraction wells. However, using a first-order decay term for tracer loss fails to describe the BTCs at the extraction well, which is affected by the nonuniform distribution of travel paths.

Analysis of the 2,909,809-bp genome will facilitate our molecular and biochemical understanding of the unusual metabolic repertoire of this bacterium, including its ability to couple denitrification to sulfur-compound oxidation, to catalyze anaerobic, nitrate-dependent oxidation of Fe(II) and U(IV), and to oxidize mineral electron donors. Notable genomic features include (i) genes encoding c-type cytochromes totaling 1 to 2 percent of the genome, which is a proportion greater than for almost all bacterial and archaeal species sequenced to date, (ii) genes encoding two [NiFe]hydrogenases, which is particularly significant because no information on hydrogenases has previously been reported for T. denitrificans and hydrogen oxidation appears to be critical for anaerobic U(IV) oxidation by this species, (iii) a diverse complement of more than 50 genes associated with sulfur-compound oxidation (including sox genes, dsr genes, and genes associated with the AMP-dependent oxidation of sulfite to sulfate), some of which occur in multiple (up to eight) copies, (iv) a relatively large number of genes associated with inorganic ion transport and heavy metal resistance, and (v) a paucity of genes encoding organic-compound transporters, commensurate with obligate chemolithoautotrophy. Ultimately, the genome sequence of T. denitrificans will enable elucidation of the mechanisms of aerobic and anaerobic sulfur-compound oxidation by beta -proteobacteria and will help reveal the molecular basis of this organism's role in major biogeochemical cycles (i.e., those involving sulfur, nitrogen, and carbon) and groundwater restoration.

We applied nonlinear and generalized linear data analysis methods to relate microbial biomarkers (phospholipids fatty acids, PLFA) to groundwater geochemical characteristics at the Shiprock uranium mill tailings disposal site that is primarily contaminated by uranium, sulfate, and nitrate. First, predictive models were constructed using feedforward artificial neural networks (NN) to predict PLFA classes from geochemistry. To reduce the danger of overfitting, parsimonious NN architectures were selected based on pruning of hidden nodes and elimination of redundant predictor (geochemical) variables. The resulting NN models greatly outperformed the generalized linear models. Sensitivity analysis indicated that tritium, which was indicative of riverine influences, and uranium were important in predicting the distributions of the PLFA classes. In contrast, nitrate concentration and inorganic carbon were least important, and total ionic strength was of intermediate importance. Second, nonlinear principal components (NPC) were extracted from the PLFA data using a variant of the feedforward NN. The NPC grouped the samples according to similar geochemistry. PLFA indicators of Gram-negative bacteria and eukaryotes were associated with the groups of wells with lower levels of contamination. The more contaminated samples contained microbial communities that were predominated by terminally branched saturates and branched monounsaturates that are indicative of metal reducers, actinomycetes, and Gram-positive bacteria. These results indicate that the microbial community at the site is coupled to the geochemistry and knowledge of the geochemistry allows prediction of the community composition.

As-prepared inorganic films, consisting of packed nanoparticles, were formed by heat-induced hydrolysis and condensation in acidic aqueous solutions of hafnium inorganic salt. The effects of several key synthesis process parameters-such as temperature, concentration of the hafnium salt, and acidity (i.e., concentration of added hydrochloric acid)-on the thickness, growth kinetics, and surface features of the films were studied through characterization by ellipsometry, atomic force microscopy, and transmission electron microscopy. In addition, solid particle precipitation in the bulk solutions was investigated with real-time dynamic light scattering and small-angle X-ray scattering techniques (for solid particle nucleation and growth kinetics) as well as with scanning electron microscopy (for visualizing solid size and morphology). The formation of hafnia films occurs right after the induction period, which is the time corresponding to the turbidity appearance due to solid particle formation in the bulk solutions. The initial growth rate of the film increases with increasing temperature and hafnium salt concentration and decreasing hydrochloric acid concentration. Our results suggest that the heterogeneous nucleation and growth mechanism might be responsible for the formation of the first layer of hafnia on the SAM surface. However, under the conditions tested, hafnia films seem to grow thicker mainly by a "cluster growth" mechanism due to adherence of nanoparticles from the bulk solutions. Although decreasing in the rate of nucleation and growth, nanoclusters or nanoparticles (continuously formed after the induction period) can still contribute to film deposition. The effects of process parameters on the film growth rate are consistent with the trend of their effects on particle growth rate in the bulk solutions. Tests of multiple batch deposition on the same surface, suggesting a liquid-flow deposition scheme, show a potential to improve film growth kinetics and to reduce film surface roughness. In comparison with zirconia systems, the hydrolysis and film growth rate for hafnia systems are slower; however, the film characteristics of hafnia are quite similar to those of zirconia.

Microarray analysis revealed that cells elicited both general and specific transcriptome responses when challenged with environmental acid (pH 4) or base (pH 10) conditions over a 60-min period. Global responses included the differential expression of genes functionally linked to amino acid metabolism, transcriptional regulation and signal transduction, transport, cell membrane structure, and oxidative stress protection. Response to acid stress included the elevated expression of genes encoding glycogen biosynthetic enzymes, phosphate transporters, and the RNA polymerase sigma-38 factor (rpoS), whereas the molecular response to alkaline pH was characterized by upregulation of nhaA and nhaR, which are predicted to encode an Na super(+)/H super(+) antiporter and transcriptional activator, respectively, as well as sulfate transport and sulfur metabolism genes. Collectively, these results suggest that S. oneidensis modulates multiple transporters, cell envelope components, and pathways of amino acid consumption and central intermediary metabolism as part of its transcriptome response to changing external pH conditions.

Transcriptome analysis was used to identify the genes of MR-1 responding to 40 Gy (D sub(20)). We observed the induction of 170 genes and repression of 87 genes in MR-1 during a 1-h recovery period after irradiation. The genomic response of MR-1 to IR is very similar to its response to UV radiation (254 nm), which included induction of systems involved in DNA repair and prophage synthesis and the absence of differential regulation of tricarboxylic acid cycle activity, which occurs in IR-irradiated D. radiodurans. Furthermore, strong induction of genes encoding antioxidant enzymes in MR-1 was observed. DNA damage may not be the principal cause of high sensitivity to IR, considering that MR-1 carries genes encoding a complex set of DNA repair systems and 40 Gy IR induces less than one double-strand break in its genome. Instead, a combination of oxidative stress, protein damage, and prophage-mediated cell lysis during irradiation and recovery might underlie this organism's great sensitivity to IR.

Over the 400-d study period the trapped gas in laboratory columns was small, with a maximum measured at 1.3% pore volume. Low levels of dissolved H (sub 2) (g) were measured (up to 0.07 + or - 0.02 M). Free moving gas bubbles were not observed. Thus, porosity loss, which was determined by tracer tests to be 25-30%, is not accounted for by residual gas trapped in the iron. The removal of aqueous species (i.e., NO (sub 3) (super -) , Ca, and carbonate alkalinity) indicates that mineral precipitation contributed more significantly to porosity loss than did the trapped gases. Using the stoichiometric reactions between Fe (super 0) and NO (sub 3) (super -) , an average corrosion rate of 1.7 mmol kg (super -1) d (super -1) was derived for the test granular iron. This rate is 10 times greater than Fe (super 0) oxidation by H (sub 2) O alone, based on H (sub 2) gas production. NO (sub 3) (super -) ion rather than H (sub 2) O was the major oxidant in the groundwater in the absence of molecular O (sub 2) . The N-mass balance [e.g., N (sub 2) (g) and NH (sub 4) (super +) and NO (sub 3) (super -) ] suggests that abiotic reduction of NO (sub 3) (super -) dominated at the start of Fe (super 0) treatment, whereas N (sub 2) production became more important once the microbial activity began. These laboratory results closely predict N (sub 2) gas production in a separated large column experiment that was operated for approximately 2 yr in the field, where a maximum of approximately 600 ml d (super -1) gas volumes was detected, of which 99.5% (v/v) was N (sub 2) . We conclude that NO (sub 3) (super -) suppressed the production of H (sub 2) (g) by competing with water for Fe (super 0) oxidation, especially at the beginning of water treatment when Fe (super 0) is highly reactive. Depends on the groundwater composition, gas venting may be necessary in maintaining PRB performance in the field. Abstract Copyright (2006) Elsevier, B.V.

AN - 734275107; 18369407 AB - Mechanisms of cellular adaptation may have some commonalities across different organisms. Revealing these common mechanisms may provide insight in the organismal level of adaptation and suggest solutions to important problems related to the adaptation. An increased rate of mutations, referred as the mutator phenotype, and beneficial nature of these mutations are common features of the bacterial stationary-state mutagenesis and of the tumorigenic transformations in mammalian cells. We argue that these commonalities of mammalian and bacterial cells result from their stress-induced adaptation that may be described in terms of a common model. Specifically, in both organisms the mutator phenotype is activated in a subpopulation of proliferating stressed cells as a strategy to survival. This strategy is an alternative to other survival strategies, such as senescence and programmed cell death, which are also activated in the stressed cells by different subpopulations. Sustained stress-related proliferative signalling and epigenetic mechanisms play a decisive role in the choice of the mutator phenotype survival strategy in the cells. They reprogram cellular functions by epigenetic silencing of cell-cycle inhibitors, DNA repair, programmed cell death, and by activation of repetitive DNA elements. This reprogramming leads to the mutator phenotype that is implemented by error-prone cell divisions with the involvement of Y family polymerases. Studies supporting the proposed model of stress-induced cellular adaptation are discussed. Cellular mechanisms involved in the bacterial stress-induced adaptation are considered in more detail.

AN - 68755961; 16915698 AB - A biological process for removal of mercury from coal is under investigation. Iron and sulfur oxidizing bacteria have previously been used for desulfurization of coal and for mineral mining. We have shown that removal of mercury from coal is also possible via the same principles. Two pure cultures, Leptospirillum ferrooxidans and Acidithiobacillus ferrooxidans and four environmental consortium samples obtained from an acid mine drainage site were studied for mercury removal from coal. Four different coal samples were included in the study and the preliminary results have shown that up to 20% of the mercury can be removed in batch cultures compared to control. Additional parameters such as media composition and inoculum size were also studied. This is the first report demonstrating successful leaching of mercury from coal using biological treatment.

AN - 57679466; 00491169 AB - The Defense Advanced Research Projects Agency Virtual Soldier Project recently investigated methods to predict outcomes from penetrating wounds based on comparison of complex mathematical models and clinical data including baseline X-ray computed tomography and post-wound imaging. A need of the project was to correlate three-dimensional anatomy to extensive information, including pathophysiology of the wounded soldier, using the anatomical geometry as an interface. To address this need, Oak Ridge National Laboratory developed the HotBox, a user interface that links a given point in space (a voxel) to the structural knowledge ontology describing the anatomy at that location. In addition, the HotBox links the location to the individual's physiological state (vital signs) and a description of the wound. The implementation and use of the HotBox is explained and the implications for the future of medical records, pre-surgical planning, image-guided surgery, and post-surgical treatment and rehabilitation are discussed.

Landfill gas (LFG) is a low-BTU gas composed of approximately 50% methane CH (sub 4) , 40% carbon dioxide (CO (sub 2) ), and 10% miscellaneous gases, including non-methane volatile organic compounds (NMVOCs). Most CH (sub 4) and CO (sub 2) generated in solid-waste landfills is flared and vented -- a practice that ignores environmental impacts and potential economic value. A possibly profitable economic option involves injecting LFG, or a CO (sub 2) enriched residual LFG gas into subsurface coal seams. Because CO (sub 2) and NMVOCs are preferentially adsorbed on coal surfaces, the CH (sub 4) concentration of LFG could be increased as it flows through a coal seam from an injection well toward a nearby production well. In addition, adsorbed CH (sub 4) present in the coal prior to LFG injection could be released as sorption proceeds, allowing additional amounts of CH (sub 4) to be produced. In this way, both profitable CH (sub 4) production and cost-effective CO (sub 2) sequestration are realized. This concept is being tested through field, laboratory, and simulation studies by injecting LFG derived from a large landfill in the Kansas City metropolitan area into underlying Middle Pennsylvanian coals. Sorption/desorption experiments provide data to model gas behavior during and after LFG injection into an underground coal seam. Gas flow-through experiments will help understand permeability changes due to swelling as LFG is adsorbed onto the coal and CH (sub 4) is desorbed from it. Widespread distribution of organic shale and coalbeds provide potential targets for such value-added sequestration.

Production is generally from multiple high-volatile A and B bituminous coals, 1 to 3 ft thick, in the Middle Pennsylvanian (Desmoinesian) Cherokee and Marmaton Groups, at depths of 500 to 1,500 ft. Enhanced coalbed natural gas (ECBNG) technologies provide possible methods to increase CBNG production, and at the same time sequester CO (sub 2) . At 5% of global CO (sub 2) production the cement industry is a major anthropogenic source of CO (sub 2) . Kiln gas, which is principally N (sub 2) , CO (sub 2) , and water vapor from the calcination process, can potentially be utilized as the injected gas for an ECBNG recovery project. The development of an ECBNG recovery project utilizing kiln gas requires a reservoir model to understand its effects on reservoir performance. Attendant to this task, well-log and core data of the Cherokee and Marmaton Groups within Wilson County, Kansas, were used to create a detailed structural and stratigraphic framework in the vicinity of a large cement plant. Production and completion data from nearby CBNG wells also were needed for determining coal-seam permeability. Desorption tests determined gas content of coals. These tests were followed by laboratory analyses of the coals to determine their gas saturation and swelling in the presence of kiln gas. A series of reservoir simulations were run to investigate methods to improve CBNG recovery, as well as assessing the geological and economic feasibility of sequestering cement-kiln emissions in subsurface coal seams.

Sampler retrieval after several days of immersion in groundwater allowed the direct injection of the sample onto a gas chromatograph (GC), simplifying field collection and sample handling over the commonly used "bubble stripping" method for H sub(2) analyses. A GC was modified by sequencing a thermal conductivity (TC) detector followed by a reductive gas (RG) detector so that linear calibration of H sub(2) over the range 0.2-200 000 ppmv was attained using a 0.5-mL gas sample; inclusion of the TC detector allowed the simultaneous quantification of other fixed gases (O sub(2), CO sub(2), He, and Ne) to which the RG detector was not responsive. Uptake kinetics for H sub(2) and He indicated that the passive sampler reached equilibrium within 12 h of immersion in water.

Enzymes are biocatalysts working as highly efficient machines at the molecular level. In the past, enzymes have been viewed as static entities and their function has been explained on the basis of direct structural interactions between the enzyme and the substrate. A variety of experimental and computational techniques, however, continue to reveal that proteins are dynamically active machines, with various parts exhibiting internal motions at a wide range of time-scales. Increasing evidence also indicates that these internal protein motions play a role in promoting protein function such as enzyme catalysis. Moreover, the thermodynamical fluctuations of the solvent, surrounding the protein, have an impact on internal protein motions and, therefore, on enzyme function. In this review, we describe recent biochemical and theoretical investigations of internal protein dynamics linked to enzyme catalysis. In the enzyme cyclophilin A, investigations have lead to the discovery of a network of protein vibrations promoting catalysis. Cyclophilin A catalyzes peptidyl-prolyl cis/trans isomerization in a variety of peptide and protein substrates. Recent studies of cyclophilin A are discussed in detail and other enzymes (dihydrofolate reductase and liver alcohol dehydrogenase) where similar discoveries have been reported are also briefly discussed. The detailed characterization of the discovered networks indicates that protein dynamics plays a role in rate-enhancement achieved by enzymes. An integrated view of enzyme structure, dynamics and function have wide implications in understanding allosteric and co-operative effects, as well as protein engineering of more efficient enzymes and novel drug design.

Black spruce and jack pine foliage both emitted and absorbed Hg(0), exhibiting compensation points near atmospheric Hg(0) concentrations of similar to 2-3 ng m super(-) super(3). Using enriched stable Hg isotope spikes, patterns of spike Hg(II) retention on foliage were investigated. Hg(0) evasion rates from foliage were simultaneously measured using the chamber to determine if the decline of foliar spike Hg(II) concentrations over time could be explained by the photoreduction and re-emission of spike Hg to the atmosphere. This mass balance approach suggested that spike Hg(0) fluxes alone could not account for the measured decrease in spike Hg(II) on foliage following application, implying that either the chamber underestimates the true photoreduction of Hg(II) to Hg(0) on foliage, or other mechanisms of Hg(II) loss from foliage, such as cuticle weathering, are in effect. The radiation spectrum responsible for the photoreduction of newly deposited Hg(II) on foliage was also investigated. Our spike experiments suggest that some of the Hg(II) in wet deposition retained by the forest canopy may be rapidly photoreduced to Hg(0) and re-emitted back to the atmosphere, while another portion may be retained by foliage at the end of the growing season, with some being deposited in litterfall. This finding has implications for the estimation of Hg dry deposition based on throughfall and litterfall fluxes.

Iron and sulfur oxidizing bacteria have previously been used for desulfurization of coal and for mineral mining. We have shown that removal of mercury from coal is also possible via the same principles. Two pure cultures, Leptospirillum ferrooxidans and Acidithiobacillus ferrooxidans and four environmental consortium samples obtained from an acid mine drainage site were studied for mercury removal from coal. Four different coal samples were included in the study and the preliminary results have shown that up to 20% of the mercury can be removed in batch cultures compared to control. Additional parameters such as media composition and inoculum size were also studied. This is the first report demonstrating successful leaching of mercury from coal using biological treatment.

The fabrication, operating principle, and applications of these systems and their capacity for in vivo analysis and optical imaging at the single-cell level are discussed. Recently the cross-disciplinary integration of nanotechnology, biology, and photonics has been revolutionizing important areas in molecular biology, especially diagnostics and therapy at the molecular and cellular levels. Nanobiosensors and nanoprobes are a relatively new class of biosensing and imaging devices that allow for analytical measurements in individual living cells. These devices have the capacity to sense individual chemical species in specific locations within a cell. This article discusses the usefulness and potential of these nanotechnology-based systems in biological research and their applications to monitoring individual living cells.

Indeed, in several ways, eastern China, especially, seems to demonstrate changes that are opposite in sign of those observed over other mid-latitude land regions of the northern hemisphere. The main variable that may be characterized as such is total cloud cover (TCC). Several studies [e.g., Kaiser (1998; 2000); Kaiser and Qian (2002)] have shown that most of China has experienced a decrease in TCC over the last half of the twentieth century, whereas most other land areas of the globe with surface- observed cloud data that show any significant change have shown increases [e.g., Angel (1990) for the United States; Jones and Henderson-Sellers (1992) for Australia]. The decrease in cloudiness over China is made even more interesting (indeed, perplexing) by the concomitant decrease in sunshine duration that is also found [Kaiser and Qian (2002)]. Normally one would of course expect that a long-term decrease in cloud amount would result in an increase in sunshine duration, but this has not been observed for China. The marked decrease in sunshine duration described in Kaiser and Qian (2002) has been attributed to well-documented increases in atmospheric anthropogenic aerosol loading (mainly sulfate) over China during recent decades due to increased fossil fuel combustion. These aerosols produce haze that is thought to enhance the backscatter and absorption of incoming solar radiation and thus weaken the direct solar radiation needed to activate the sunshine recorder, especially early and late in the day when the atmospheric path length is greater. A related question still to be resolved is: How might this increased atmospheric haze affect the ability of surface observers to estimate the fraction of the celestial dome covered by clouds? Could the increased haze at least in part be responsible for the decreasing trend in TCC? In this presentation we will attempt to answer this question by comparing the surface-observed TCC record over China with ISCCP satellite observations available for the common data period of 1984-2002. While it is known that satellite estimates of TCC are typically greater than concurrent surface-observed TCC, we will be comparing the correlation and trends from the two records in order to see if they differ in such a way as to explain any effect the aerosol haze might have on the surface- based observations. We will also present updates of and examine relationships between several other primary meteorological variables for China, such as near- surface air temperature, precipitation, evaporation, relative humidity, soil moisture, and solar irradiance. Along with looking at things at the individual station level and at the country level, as in our past analyses of Chinese climate, we will also use a gridded analysis to depict trends, correlations, and their statistical significance.

Results of previous environmental monitoring suggested limited mobilization in the impact area and no transport of du into the nation's largest estuary. To determine if physical and biological reactions constitute mechanisms involved in limiting contaminant transport, the sorption and biotransformation behavior of the radionuclide was studied using geochemical modeling and laboratory microcosms (500 ppb U(VI) initially). An immediate decline in dissolved U(VI) concentrations was observed under both sterile and non-sterile conditions due to rapid association of U(VI) with natural organic matter in the sediment. Reduction of U(VI) to U(IV) occurred only in non-sterile microcosms. In the non-sterile samples, intrinsic bioreduction of uranium involved bacteria of the order Clostridiales and was only moderately enhanced by the addition of acetate (41% vs. 56% in 121 days). Overall, this study demonstrates that the migration of depleted uranium from the APG site into the Chesapeake Bay may be limited by a combination of processes that include rapid sorption of U(VI) species to natural organic matter, followed by slow, intrinsic bioreduction to U(IV). At the Aberdeen Proving Ground in Maryland, USA, migration of depleted uranium into the Chesapeake Bay is limited by rapid sorption of the radionuclide to natural organic matter followed by slow biological reduction of water-soluble U(VI) to the insoluble and less toxic U(IV) species.

The problem has been investigated in small scale (1-2 L) digesters in the laboratory; however, very little scale-up to intermediate scales are available. We report production of methane in a 100-L digester and the results of an investigation into the effect of partial mixing induced by gas upflow/recirculation in the digester. The digester was operated for a period of about 70 d (with 16-d hydraulic retention time) with and without the mixing induced by gas recirculation through an internal draft tube. The results show a clear effect of mixing on digester operation. Without any mixing, the digester performance deteriorated within 30-50 d, whereas with mixing continuous production of methane was observed. This study demonstrates the importance of mixing and its critical role in design of large scale anaerobic digesters.

However, few studies have examined the response of deciduous forests to increases or decreases in precipitation. Therefore, the throughfall displacement experiment (TDE) was established in 1993 near Oak Ridge, Tennessee to examine the sensitivity of an upland oak (Quercus spp.) forest to ambient, wet (+33%), and dry (-33%) precipitation regimes. Sap flux measurements on co-occurring tree species were scaled using species-specific estimates of stand sapwood area to derive daily and seasonal rates of canopy transpiration (E sub(C)) from 2000 to 2003. With the exception of 2003, which was an extremely wet year, daily E sub(C) in the dry plot, and occasionally during extended droughts in the ambient and wet plots, declined as water potential in the upper 0.35 m soil profile approached -3.0 MPa. Seasonal patterns of soil water potential and treatment-specific differences in E sub(C) were dependent on precipitation frequency and intensity. Supplemental precipitation added to the wet plot increased seasonal E sub(C) on average by 9% (range -1% to 19%), whereas extended periods of drought on the dry plot in 2000, 2001, and 2002 were sufficient to reduce seasonal E sub(C) by 26-30% compared with the ambient plot. There was a strong correlation between seasonal E sub(C) and the water stress integral, a cumulative index of drought severity and duration. A polynomial fitted to these data indicated that reductions in seasonal E sub(C) on the order of 40% were possible given TDE-imposed reductions in soil water potential. Application of this equation to all years of the TDE (1994-2003) revealed considerable interannual and treatment-specific variation in canopy transpiration. In general, a 33% removal of throughfall on the dry plot during 1995, 1998, and 2002 resulted in a 23-32% reduction in seasonal E sub(C) compared with the ambient plot. While droughts in deciduous forests are often limited in duration and tend to occur late in the growing season, soil water deficits of the magnitude observed in this study have the potential to impact local and regional forest water budgets.

But there is a lack of high-throughput methods to elucidate recognition events between carbohydrates and proteins. This paper reported a convenient and efficient method for preparing oligosaccharide microarrays, wherein the underivatized oligosaccharide probes were efficiently immobilized on aminooxyacetyl functionalized glass surface by formation of oxime bonding with the carbonyl group at the reducing end of the suitable carbohydrates via irreversible condensation. Prototypes of carbohydrate microarrays containing 10 oligosaccharides were fabricated on aminooxyacetyl functionalized glass by robotic arrayer. Utilization of the prepared carbohydrate microarrays for the characterization of carbohydrate-protein interaction reveals that carbohydrates with different structural features selectively bound to the corresponding lectins with relative binding affinities that correlated with those obtained from solution-based assays. The limit of detection (LOD) for lectin ConA on the fabricated carbohydrate microarrays was determined to be 0.008 mu g/mL. Inhibition experiment with soluble carbohydrates also demonstrated that the binding affinities of lectins to different carbohydrates could be analyzed quantitatively by determining IC sub(50) values of the soluble carbohydrates with the carbohydrate microarrays. This work provides a simple procedure to prepare carbohydrate microarray for high-throughput parallel characterization of carbohydrate-protein interaction.

These models can be useful for determining binding energetics, predicting the structures of specific ternary complexes with T-cell receptors, and designing new molecules interacting with these complexes. The main difficulties are (1) adequate sampling of the large number of conformational degrees of freedom for the flexible peptide, (2) predicting subtle changes in the MHC interface geometry upon binding, and (3) building models for numerous MHC allotypes without known structures. Whereas previous studies have approached the sampling problem by dividing the conformational variables into different sets and predicting them separately, we have refined the Biased-Probability Monte Carlo docking protocol in internal coordinates to optimize a physical energy function for all peptide variables simultaneously. We also imitated the induced fit by docking into a more permissive smooth grid representation of the MHC followed by refinement and reranking using an all-atom MHC model. Our method was tested by a comparison of the results of cross-docking 14 peptides into HLA-A*0201 and 9 peptides into H-2K super()bas well as docking peptides into homology models for five different HLA allotypes with a comprehensive set of experimental structures. The surprisingly accurate prediction (0.75 Aa backbone RMSD) for cross-docking of a highly flexible decapeptide, dissimilar to the original bound peptide, as well as docking predictions using homology models for two allotypes with low average backbone RMSDs of less than 1.0 Aa illustrate the method's effectiveness. Finally, energy terms calculated using the predicted structures were combined with supervised learning on a large data set to classify peptides as either HLA-A*0201 binders or nonbinders. In contrast with sequence-based prediction methods, this model was also able to predict the binding affinity for peptides to a different MHC allotype (H-2K super()b, not used for training, with comparable prediction accuracy.

By means of this process, an entire neural stimulation circuit, including stimulating electrode, connection trace, and contact pad, can be fused into one continuous, integrated structure where different sections can have different heights, widths, and shapes. The technique is suitable for mass production, and the fabricated electrode is robust and very flexible. More importantly for biomedical applications, the entire fabricated structure can be packed at room temperature onto a biocompatible flexible substrate, such as polydimethylsiloxane, parylene, and polyimide as well as other temperature- sensitive or vacuum-sensitive materials. The electrodes and wires have about the same electrical resistivities as bulk materials and desirable electrochemical properties, including low impedance.

Catchments at the Fort Benning Military Installation (near Columbus, Georgia) experience a range of upland disturbance intensities due to spatial variability in the intensity of military training. We used this disturbance gradient to investigate the effects of upland soil and vegetation disturbance on stream chemistry. During baseflow, mean total suspended sediment (TSS) concentration and mean inorganic suspended sediment (ISS) concentration increased with catchment disturbance intensity (TSS: R super(2) = 0.7, p = 0.005, range = 4.0-10.1 mg L super(-1); ISS: R super(2) = 0.71, p = 0.004, range = 2.04-7.3 mg L super(-1)); dissolved organic carbon (DOC) concentration (R super(2) = 0.79, p = 0.001, range = 1.5-4.1 mg L super(-1)) and soluble reactive phosphorus (SRP) concentration (R super(2) = 0.75, p = 0.008, range = 1.9-6.2 kg L super(-1)) decreased with increasing disturbance intensity; and ammonia (NH sub(4) super(+)), nitrate (NO sub(3) super(-)), and dissolved inorganic nitrogen (DIN) concentrations were unrelated to disturbance intensity. The increase in TSS and ISS during storms was positively correlated with disturbance (R super(2) = 0.78 and 0.78, p = 0.01 and 0.01, respectively); mean maximum change in SRP during storms increased with disturbance (r = 0.7, p = 0.04); and mean maximum change in NO sub(3) super(-) during storms was marginally correlated with disturbance (r = 0.58, p = 0.06). Soil characteristics were significant predictors of baseflow DOC, SRP, and Ca super(2+), but were not correlated with suspended sediment fractions, any nitrogen species, or pH. Despite the largely intact riparian zones of these headwater streams, upland soil and vegetation disturbances had clear effects on stream chemistry during baseflow and stormflow conditions.

Antibodies or antigens were immobilized in the PET-coated glass slides by electrostatic adsorption and entrapment of porous structure of the 3-D polymer film and thus establishing a platform for parallel analysis. Both antigen and antibody microarrays were fabricated on the PET-coated slides, and direct and indirect immunoassays on protein microarrays for multiple-analyte detection were demonstrated. Microarrays produced on these PET-coated slides have consistent spot morphology and provide performance features needed for proteomic analysis. The protein microarrays on the PET films provide LOD as low as 6 pg/mL and dynamic ranges up to three orders of magnitude, which are wider than the protein microarrays fabricated on aldehyde and poly-L-lysine functionalized slides. The PET films constructed by self-assembly technique in aqueous solution is green chemistry based, cost-effective method to generate 3-D thin film coatings on glass surface, and the coated slide is well suited for immobilizing many types of biological molecules so that a wide variety of microarray formats can be developed on this type of slide.

We have implemented a C library, named libSRES, to facilitate a fast implementation of computer software for study of non-linear biochemical pathways. This library implements a ( mu , lambda )-ES evolutionary optimization algorithm that uses stochastic ranking as the constraint handling technique. Considering the amount of computing time it might require to solve a parameter-estimation problem, an MPI version of libSRES is provided for parallel implementation, as well as a simple user interface. libSRES is freely available and could be used directly in any C program as a library function. We have extensively tested the performance of libSRES on various pathway parameter-estimation problems and found its performance to be satisfactory.

The lignin contents varied from 22.7% to 25.8% and the S/G ratio from 1.8 to 2.3. Selected samples spanning these ranges were hydrolyzed with dilute (1%) sulfuric acid to release fermentable sugars. The conditions were chosen for partial hydrolysis of the hemicellulosic fraction to maximize the expression of variation among samples. The results indicated that both lignin contents and S/G ratio significantly affected the yield of xylose. For example, the xylose yield of the 25.8% lignin and 2.3 S/G (high lignin, high S/G) sample produced 30% of the theoretical yield, whereas the xylose yield of the 22.7% lignin and 1.8 S/G (low lignin, low S/G) was 55% of the theoretical value. These results indicate that lignin content and composition among genetic variants within a single species can influence the hydrolyzability of the biomass.

Here, we present a six-year record of N dynamics of a sweetgum (Liquidambar styraciflua) stand exposed to elevated [CO sub(2)] in the free-air CO sub(2) enrichment (FACE) experiment at Oak Ridge, Tennessee, USA. We also evaluate the concept of PNL for this ecosystem from the perspective of N uptake, content, distribution, and turnover, and N-use efficiency. Leaf N content was 11 % lower on a leaf mass basis (N sub(M)) and 7% lower on a leaf area basis (N sub(A)) in CO sub(2)-enriched trees. However, there was no effect of [CO sub(2)] on total canopy N content. Resorption of N during senescence was not altered by [CO sub(2)], so N sub(M) of litter, but not total N content, was reduced. The N sub(M) of fine roots was not affected, but the total amount of N required for fine-root production increased significantly, reflecting the large stimulation of fine-root production in this stand. Hence, total N requirement of the trees was higher in elevated [CO sub(2)], and the increased requirement was met through an increase in N uptake rather than increased retranslocation of stored reserves. Increased N uptake was correlated with increased net primary productivity (NPP). N-use efficiency, however, did not change with CO sub(2) enrichment because increased N productivity was offset by lower mean residence time of N in the trees. None of the measured responses of plant N dynamics in this ecosystem indicated the occurrence of PNL, and the stimulation of NPP by elevated [CO sub(2)] was sustained for the first six years of the experiment. Although there are some indications of developing changes in the N economy, the N supply in the soil at this site may be sufficient to meet an increasing demand for available N, especially as the roots of CO sub(2)-enriched trees explore deeper in the soil profile.

Studies indicated that MR-1 was able to grow aerobically in complex medium in the presence of 180 mM SrCl sub(2) but showed severe growth inhibition at levels above that concentration. Temporal gene expression profiles were generated from aerobically grown, mid-exponential-phase MR-1 cells shocked with 180 mM SrCl sub(2) and analyzed for significant differences in mRNA abundance with reference to data for nonstressed MR-1 cells. Genes with annotated functions in siderophore biosynthesis and iron transport were among the most highly induced (>100-fold [P < 0.05]) open reading frames in response to acute Sr stress, and a mutant (SO3032::pKNOCK) defective in siderophore production was found to be hypersensitive to SrCl sub(2) exposure, compared to parental and wild-type strains. Transcripts encoding multidrug and heavy metal efflux pumps, proteins involved in osmotic adaptation, sulfate ABC transporters, and assimilative sulfur metabolism enzymes also were differentially expressed following Sr exposure but at levels that were several orders of magnitude lower than those for iron transport genes. Precipitate formation was observed during aerobic growth of MR-1 in broth cultures amended with 50, 100, or 150 mM SrCl sub(2) but not in cultures of the SO3032::pKNOCK mutant or in the abiotic control. Chemical analysis of this precipitate using laser-induced breakdown spectroscopy and static secondary ion mass spectrometry indicated extracellular solid-phase sequestration of Sr, with at least a portion of the heavy metal associated with carbonate phases.

A batch test was performed to study the biodegradability of the wastewater, and the result indicated that a combination anaerobic-aerobic treatment system was effective in removing organic matter from the high-strength pharmaceutical wastewater. Based on the batch test, a pilot-scale system composed of an anaerobic baffled reactor followed by a biofilm airlift suspension reactor was designed. At a stable operational period, effluent chemical oxygen demand (COD) from the anaerobic baffled reactor ranged from 1,432 to 2,397 mg/L at a hydraulic retention time (HRT) of 1.25 day, and 979 to 1,749 mg/L at an HRT of 2.5 day, respectively, when influent COD ranged from 9,736 to 19,862 mg/L. As a result, effluent COD of the biofilm airlift suspension reactor varied between 256 and 355 mg/L at HRTs of from 5.0 to 12.5 h. The antibiotics ampicillin and aureomycin, with influent concentrations of 3.2 and 1.0 mg/L, respectively, could be partially degraded in the anaerobic baffled reactor: ampicillin and aureomycin removal efficiencies were 16.4 and 25.9% with an HRT of 1.25 day, and 42.1 and 31.3% with HRT of 2.5 day, respectively. Although effective in COD removal, the biofilm airlift suspension reactor did not display significant antibiotic removal, and the removal efficiencies of the two antibiotics were less than 10%.

Simulated effects of translocation on white sturgeon AN - 17103184; 6729930 AB - Restoring connectivity is viewed as an important recovery option for fish species adversely affected by river fragmentation. This simulation study quantified the genetic and demographic effects of translocation on metapopulations of white sturgeon (Acipenser transmontanus) inhabiting a series of long (source) and short (sink) river segments. Genetic effects were predictable; upstream translocations increased introgression and downstream translocations had no effect. Demographic results suggest that indiscriminant effort to reconnect populations may do more harm than good. Simulated river systems with high interspersion of long and short segments and along segments far upstream tended to benefit most from translocation, but only when narrow screening or downstream passage was also provided below the river segment receiving fish. When combined with narrow screening, upstream translocation to a long segment subsidizing several downstream short segments produced the best results. Downstream passage outperformed narrow screening only when the translocation recipient was a short segment in a river system with low interspersion and no long, upstream river segment. This model-based evaluation of reconnection options has helped to refine ideas about restoring populations in fragmented rivers by predicting which options benefit riverine metapopulations as a whole.

Simulated effects of upstream passage on white sturgeon. AN - 17101123; 6729929 AB - River fragementation by dams has often preceded declines in sturgeon populations, which suggests that reconnecting populations would contribute to their recovery. This study used a population viability model to quantify the effects of upstream passage at dams on white sturgeon (Acipenser transmontanus) metapopulations inhabitating a series of long (source) and short (sink) river segments. Simulated river systems with high interspersion of long and short segments and a long segment far upstream supported the healthiest metapopulations, suggesting biological criteria for siting dams. Contary to expectation, the model predicted that upstream passage, without screening or downstream passage, was harmful to the metapopulation as a whole. However, upstream passage was beneficial when downstream migration was either restricted (by screening larger fish) or made safe (by providing downstream passage). The combination of upstream and downstream passage was most beneficial at dams above a long river segment. Screening, alone or combined with upstream passage, was most beneficial at dams below a long segment. These theoretical results highlight the need for filed research to evaluate management options and provide practical guidance for restoring sturgeon metapopulations in large rivers.

AN - 68891269; 16351154 AB - Use of a porous flow-through electrode at the upstream ground contact or at both the upstream ground contact and the high-voltage emitter contact in an electrospray ion source was shown to provide for new types of electrochemical experiments utilizing only the electrochemistry inherent to electrospray. The normal stainless steel bore-through union serving as the upstream grounding point in a floated electrospray emitter system was replaced with a high surface area porous flow-through electrode assembly to achieve effective electrochemical reduction of analytes at this point in positive ion mode, and effective electrochemical oxidation of analytes in negative ion mode. This was demonstrated by the oxidation of 3,4-dihydroxybenzoic acid and reserpine in negative ion mode and by the reduction of thionine in positive ion mode. In the case of reversible oxidation (3,4-dihydroxybenzoic acid) and reduction (thionine) processes, partial rereduction and reoxidation of the products due to reaction with products generated by cathodic and anodic processes at the emitter were observed, respectively. By implementing two high surface area porous flow-through electrodes in the system, one as the upstream grounding point and the other as the emitter electrode, a multiple-step reaction scheme was achieved that included consecutive electrochemical reduction and oxidation reactions and a following chemical reaction as demonstrated by the hydroquinone tagging of an initially disulfide-linked peptide.

AN - 69062529; 16390591 AB - Perchlorate (ClO4-) has recently emerged as a widespread contaminant in drinking water and groundwater supplies in the United States, and a need exists for rapid detection and monitoring of this contaminant. In this study, surface-enhanced Raman spectroscopy (SERS) was studied as a means of ClO4- detection, and new sol-gel-based SERS substrates were developed by self-assembly of silver colloidal nanoparticles with various functionalized silane reagents. These substrate materials were tailored to allow detection of ClO4- in water with improved sorptivity, stability, and sensitivity and with the ability to detect ClO4- at concentrations as low as 10(-6) M (or 100 microg/L) with good reproducibility. Similar techniques were used to fabricate capillary SERS flow cells by assembling functionalized silver nanoparticles capable of attracting ClO4- to the SERS surface or the internal wall of glass capillaries. These capillary flow cells could be readily configured to allow for in situ, nondestructive detection of ClO4- via fiber optics.

Here we present the genome of B. abortus 2308, the virulent prototype biovar 1 strain, and its comparison to the two other human pathogenic Brucella species and to B. abortus field isolate 9-941. The global distribution of pseudogenes, deletions, and insertions supports previous indications that B. abortus and B. melitensis share a common ancestor that diverged from B. suis. With the exception of a dozen genes, the genetic complements of both B. abortus strains are identical, whereas the three species differ in gene content and pseudogenes. The pattern of species-specific gene inactivations affecting transcriptional regulators and outer membrane proteins suggests that these inactivations may play an important role in the establishment of host specificity and may have been a primary driver of speciation in the genus BRUCELLA: Despite being nonmotile, the brucellae contain flagellum gene clusters and display species-specific flagellar gene inactivations, which lead to the putative generation of different versions of flagellum-derived structures and may contribute to differences in host specificity and virulence. Metabolic changes such as the lack of complete metabolic pathways for the synthesis of numerous compounds (e.g., glycogen, biotin, NAD, and choline) are consistent with adaptation of brucellae to an intracellular life-style.

RuBisCo enzyme with an enhanced CO sub(2)/O sub(2) specificity would boost the ability to make great progress in agricultural production and environmental management. RuBisCos in marine non-green algae, resulting from an earlier endo-symbiotic event, diverge greatly from those in green plants and cyanobacteria and, further, have the highest CO sub(2)/O sub(2) specificity whereas RuBisCos in cyanobacteria have the lowest. We assumed that there exist different levels of CO sub(2)/O sub(2) specificity-determining factors, corresponding to different evolutionary events and specificity levels. Based on this assumption, we devised a scheme to identify these substrate-determining factors. From this analysis, we are able to discover different categories of the CO sub(2)/O sub(2) specificity-determining factors that show which residue substitutions account for (relatively) small specificity changes, as happened in green plants, or a tremendous enhancement, as observed in marine non-green algae. Therefore, the analysis can improve our understanding of molecular mechanisms in the substrate specificity development and prioritize candidate specificity-determining surface residues for site-directed mutagenesis.

6904110 AB - Estimates of contaminant fluxes from DNAPL sources as a function of time and DNAPL mass reduction are important to assess the long-term sustainability and costs of monitored natural attenuation and to determine the benefits of partial source removal. We investigate the accuracy of the upscaled mass transfer function (MTF) proposed by Parker and Park [Parker JC, Park E. Modeling field- scale dense nonaqueous phase liquid dissolution kinetics in heterogeneous aquifers. WRR 2004; 40:W05109] to describe field-scale dissolved phase fluxes from DNAPL sources for a range of scenarios generated using high-resolution 3-D numerical simulations of DNAPL infiltration and long-term dissolved phase transport. The results indicate the upscaled MTF is capable of accurately describing field-scale DNAPL dissolution rates as a function of time. For finger-dominated source regions, an empirical mass depletion exponent in the MTF takes on values greater than one which results in predicted mass flux rates that decrease continuously with diminishing DNAPL mass over time. Lens-dominated regions exhibit depletion exponents less than one, which results in more step- function like mass flux versus time behavior. Mass fluxes from DNAPL sources exhibiting both lens- and finger-dominated subregions were less accurately described by the simple MTF, but were well described by a dual-continuum model of the same form for each subregion. The practicality of calibrating a dual- continuum model will likely depend on the feasibility of obtaining spatially resolved field measurements of contaminant fluxes or concentrations associated with the subregions using multilevel sampling or some other means.

Land-use impacts on ecological processes include local extirpations, introductions of new species, changes in land-cover extent, changes in juxtaposition of land-cover types, changes to disturbance regimes, changes in vegetation structure and composition, and effects on air, water, and light quality, and noise pollution. Effects of land-use changes on ecological processes are discussed with special reference to changes in rural environments. Our premise is that better understanding of ecological processes improves land management. Mitigation strategies are presented with respect to management of initial ecological conditions, of the changes themselves, and of the altered system. The paper focuses on proactive environmental management efforts and identifies key research issues as (1) quantifying land-use legacies, (2) determining conditions under which land use modifies impacts of other stressors, (3) identifying conditions under which deleterious impacts can be avoided, (4) understanding cumulative impacts of land-use change, (5) improving our understanding of how land use alters resistance or susceptibility to invasion and impacts of pollutants, (6) crafting socioeconomically reasonable incentives for restoring or reducing effects of land-use practices, and (7) accelerating the integration of social and ecological sciences.

One critical feedback occurs if C uptake by the biosphere increases in response to the fossil-fuel driven increase in atmospheric [CO sub(2)] ("CO sub(2) fertilization"), thereby slowing the rate of increase in atmospheric [CO sub(2)]. Carbon exchanges between the terrestrial biosphere and atmosphere are often first represented in models as net primary productivity (NPP). However, the contribution of CO sub(2) fertilization to the future global C cycle has been uncertain, especially in forest ecosystems that dominate global NPP, and models that include a feedback between terrestrial biosphere metabolism and atmospheric [CO sub(2)] are poorly constrained by experimental evidence. We analyzed the response of NPP to elevated CO sub(2) ( approximately 550 ppm) in four free-air CO sub(2) enrichment experiments in forest stands. We show that the response of forest NPP to elevated [CO sub(2)] is highly conserved across a broad range of productivity, with a stimulation at the median of 23 plus or minus 2%. At low leaf area indices, a large portion of the response was attributable to increased light absorption, but as leaf area indices increased, the response to elevated [CO sub(2)] was wholly caused by increased light-use efficiency. The surprising consistency of response across diverse sites provides a benchmark to evaluate predictions of ecosystem and global models and allows us now to focus on unresolved questions about carbon partitioning and retention, and spatial variation in NPP response caused by availability of other growth limiting resources.

The facility was involved in a variety of research programmes, including nuclear fuel fabrication, spent nuclear fuel decladding, and reactor operation and disassembly. Most of the documented intakes involved inhalation of enriched uranium (U), fission products, or plutonium (Pu). Highest doses were estimated for a group of workers exposed to airborne uranium aluminide (UAl sub(x)) during the fabrication of reactor fuel plates. Much of the exposure to UAl sub(x) occurred early in the fuel fabrication programme, before it was recognised that intake and lung retention were being underestimated from urinary data due to an unexpected delayed dissolution of the inhaled material. In workers who had been removed from exposure, the rate of urinary excretion of U increased for a few months, peaked, and then declined at a rate consistent with moderately soluble material. This pattern differs markedly from the monotonically decreasing absorption rates represented by the default absorption types in the Human Respiratory Tract Model (HRTM) of the International Commission on Radiological Protection (ICRP). This paper summarises the findings on the behaviour of UAl sub(x) in these workers and describes material-specific parameter values of the HRTM based on this information.

AN - 69058723; 16300676 AB - BACKGROUNDAnalysis of an allelic series of point mutations in a gene, generated by N-ethyl-N-nitrosourea (ENU) mutagenesis, is a valuable method for discovering the full scope of its biological function. Here we present an efficient gene-driven approach for identifying ENU-induced point mutations in any gene in C57BL/6J mice. The advantage of such an approach is that it allows one to select any gene of interest in the mouse genome and to go directly from DNA sequence to mutant mice.RESULTSWe produced the Cryopreserved Mutant Mouse Bank (CMMB), which is an archive of DNA, cDNA, tissues, and sperm from 4,000 G1 male offspring of ENU-treated C57BL/6J males mated to untreated C57BL/6J females. Each mouse in the CMMB carries a large number of random heterozygous point mutations throughout the genome. High-throughput Temperature Gradient Capillary Electrophoresis (TGCE) was employed to perform a 32-Mbp sequence-driven screen for mutations in 38 PCR amplicons from 11 genes in DNA and/or cDNA from the CMMB mice. DNA sequence analysis of heteroduplex-forming amplicons identified by TGCE revealed 22 mutations in 10 genes for an overall mutation frequency of 1 in 1.45 Mbp. All 22 mutations are single base pair substitutions, and nine of them (41%) result in nonconservative amino acid substitutions. Intracytoplasmic sperm injection (ICSI) of cryopreserved spermatozoa into B6D2F1 or C57BL/6J ova was used to recover mutant mice for nine of the mutations to date.CONCLUSIONSThe inbred C57BL/6J CMMB, together with TGCE mutation screening and ICSI for the recovery of mutant mice, represents a valuable gene-driven approach for the functional annotation of the mammalian genome and for the generation of mouse models of human genetic diseases. The ability of ENU to induce mutations that cause various types of changes in proteins will provide additional insights into the functions of mammalian proteins that may not be detectable by knockout mutations.

AN - 68844276; 16318194 AB - A compact frequency-modulated, continuous wave (FM-cw) lidar system for measurement of distributed aerosol plumes and hard targets is presented. The system is based on intensity modulation of a laser diode and quadrature detection of the return signals. The advantages of using laser diode amplitude modulation and quadrature detection is a large reduction in the hardware required for processing and storing return signals as well as the availability of off-the-shelf integrated electronic components from the wireless and telecommunication communities. Equations to invert the quadrature signal components and determine spatial distributions of multiple targets are derived. Spatial scattering intensities are used to extract aerosol backscatter coefficients, which can then be directly compared to microphysics aerosol models for environmental measurements. Finally, results from laboratory measurements with a monostatic FM-cw lidar system with both hard targets and aerosols are discussed.

AN - 68690937; 16126304 AB - Geochemical and mineralogical changes were evaluated at a field Fe0-PRB at the Oak Ridge Y-12 site concerning operation performance during the treatment of U in high NO3- groundwater. In the 5-yr study period, the Fe0 remained reactive as shown in pore water monitoring data, where increases in pH and the removal of certain ionic species persisted. However, coring revealed varying degrees of cementation. After 3.8-yr treatment, porosity reduction of up to 41.7% was obtained from mineralogical analysis on core samples collected at the upgradient gravel-Fe0 interface. Elsewhere, Fe0 filings were loose with some cementation. Fe0 corrosion and pore volume reduction at this site are more severe due to the presence of NO3- at a high level. Tracer tests indicate that hydraulic performance deteriorated: the flow distribution was heterogeneous and under the influence of interfacial cementation a large portion of water was diverted around the Fe0 and transported outside the PRB. Based on the equilibrium reductions of NO3- and SO4(2-) by Fe0 and mineral precipitation, geochemical modeling predicted a maximum of 49% porosity loss for 5 yr of operation. Additionally, modeling showed a spatial distribution of mineral precipitate volumes, with the maximum advancing from the interface toward downgradient with time. This study suggests that water quality monitoring, coupled with hydraulic monitoring and geochemical modeling, can provide a low-cost method for assessing PRB performance.

Homologous genes for both C-P lyase and phosphonatase degradative pathways are distributed in distantly related bacterial species. The phn gene clusters for the C-P lyase pathway show great structural and compositional variation among organisms, but all contain phnG-phnM genes that are essential for C-P bond cleavage. In the gamma -proteobacterium Erwinia carotovora, genes common to phosphonate biosyntheses were found in neighboring positions of those for the C-P lyase degradative pathway and in the same transcriptional direction. A gene encoding a hypothetical protein DUF1045 was found predominantly associated with the phn gene cluster and was predicted functionally related to C-P bond cleavage. Genes for phosphonate degradation are frequently located in close proximity of genes encoding transposases or other mobile elements. Phylogenetic analyses suggest that both degradative pathways have been subject to extensive lateral gene transfers during their evolution. The implications of plasmids and transposition in the evolution of phosphonate degradation are also discussed.

Stressors such as noise, ozone, and ozone precursors cross installation boundaries, and effects of urbanization and highway development are regional in scale. Ecological populations are not limited to one side of the installation boundary. Therefore, a framework for transboundary ecological risk assessment at military installations is under development. This article summarizes the problem formulation stage. Components include: (1) regional management goals such as installation Integrated Natural Resources Management Plans and land acquisition, (2) involvement of multiple stressors, and (3) large- scale assessment endpoint entities. Challenges of selecting measures of exposure include: quantifying exposure to aggregate stressors, describing land cover consistently in the region, describing rates of land-cover transition, scaling local measurements to a region, and aggregating or isolating exposures from within and outside of the installation. Measures of effect that are important to transboundary or regional ecological risk assessments at military installations are those that represent: effects at a distance from the stressor, large-scale effects, effects of habitat change or fragmentation, spatial extrapolations of localized effects, and integrated effects of multiple stressors. These factors are reflected in conceptual models.

Radiometals that home naturally to bone can be exploited for this purpose, and super(223)Ra (t sub(1/2) = 11.4 days) recently has been studied for therapy of bone tumors in mice and rats. Actinium-225 (t sub(1/2) = 10 days) is also an attractive radioisotope for endoradiotherapy. In a single decay of a super(225)Ac nucleus and its subsequent decay daughters, over 27 MeV ( similar to 90% of total energy) is released by sequential emission of four alpha particles, ranging in energy from 5.7 to 8.4 MeV. Although Ac super(3+) does not home naturally to bone, its parent radioisotope super(225)Ra ( beta super(-), t sub(1/2) = 15 days) can be used as an in vivo source for super(225)Ac. Thus, injection of super(225)Ra takes advantage of the bone-homing properties of radium coupled with the significant amount of energy released from the super(225)Ac decay chain. Our data confirm that a large fraction of radium citrate injected intravenously into mice localizes rapidly in bone. Injected doses per gram (ID/g) for super(225)Ra range from 25% in skull to about 10% in sternum. Once deposited, the super(225)Ra remains in the bone with a biological half life of >40 days. Furthermore, >95% of the daughter radioisotope, super(225)Ac, is retained in the bone. However, a significant fraction of one of the daughter radioisotopes, super(213)Bi, is found in kidney. The biodistribution data indicate that super(225)Ra injection should be a powerful agent for killing cells associated with bone; however, the toxicity of this radioisotope which is similar to that of other a emitters limits the dose that can be tolerated.

The same control, cells pregrown with nitrate and incubated with no electron acceptor, was used for the two time points considered and for both metals. U(VI)-reducing conditions resulted in the upregulation ( greater than or equal to 3-fold) of 121 genes, while 83 genes were upregulated under Cr(VI)-reducing conditions. A large fraction of the genes upregulated [34% for U(VI) and 29% for Cr(VI)] encode hypothetical proteins of unknown function. Genes encoding proteins known to reduce alternative electron acceptors [fumarate, dimethyl sulfoxide, Mn(IV), or soluble Fe(III)] were upregulated under both U(VI)- and Cr(VI)-reducing conditions. The involvement of these upregulated genes in the reduction of U(VI) and Cr(VI) was tested using mutants lacking one or several of the gene products. Mutant testing confirmed the involvement of several genes in the reduction of both metals: mtrA, mtrB, mtrC, and menC, all of which are involved in Fe(III) citrate reduction by MR-1. Genes encoding efflux pumps were upregulated under Cr(VI)- but not under U(VI)-reducing conditions. Genes encoding proteins associated with general (e.g., groL and dnaJ) and membrane (e.g., pspBC) stress were also upregulated, particularly under U(VI)-reducing conditions, pointing to membrane damage by the solid-phase reduced U(IV) and Cr(III) and/or the direct effect of the oxidized forms of the metals. This study sheds light on the multifaceted response of MR-1 to U(VI) and Cr(VI) under anaerobic conditions and suggests that the same electron transport pathway can be used for more than one electron acceptor.

The sensing elements, based on yttria-stabilized zirconia substrates, could be current-biased to a 'NO-selective'sensing condition (for NOx in the concentration range 50-1500ppmV) if the oxide was an alkaline earth-modified lanthanum chromite. Simple variations in electrode geometry (interdigitation of the electrodes or increase of the oxide electrode surface area relative to the Pt electrode) did not affect the magnitude of the NO response or the recovery from exposure to NO. The main effects of temperature appeared to be a decrease in the response magnitude with increasing T and an increase of the recovery time (from NO exposure) with decreasing T.

Transcriptome data indicated that the 32 genes in the nif gene cluster, but not the anf or vnf genes, were induced in wild-type and Mo nitrogenase-expressing strains grown under nitrogen-fixing conditions in Mo-containing medium. Strains that were unable to express a functional Mo nitrogenase due to mutations in Mo nitrogenase structural genes synthesized functional V and Fe nitrogenases and expressed vnf and anf genes in nitrogen-fixing growth media that contained Mo and V at concentrations far in excess of those that repress alternative nitrogenase gene expression in other bacteria. Thus, not only does R. palustris have multiple enzymatic options for nitrogen fixation, but in contrast to reports on other nitrogen-fixing bacteria, the expression of its alternative nitrogenases is not repressed by transition metals. Between 95 and 295 genes that are not directly associated with nitrogenase synthesis and assembly were induced under nitrogen-fixing conditions, depending on which nitrogenase was being used by R. palustris. Genes for nitrogen acquisition were expressed at particularly high levels during alternative nitrogenase-dependent growth. This suggests that alternative nitrogenase-expressing cells are relatively starved for nitrogen and raises the possibility that fixed nitrogen availability may be the primary signal that controls the synthesis of the V and Fe nitrogenases.

AN - 68660764; 16157353 AB - The reported untreated mouse control data from the Oak Ridge National Laboratory assessment of dominant damage (ADD) experiments demonstrate a strong negative correlation between body weight at 4, 5, 7, 9, and 11 weeks of age and number in litter at 3 weeks of age. Independently from the above finding, mother mice are also shown to differ substantially as to the mean weights of their litters. Much literature suggests that, as a general rule, (a) heavier mice are more likely to develop spontaneous and induced tumors earlier and (b) caloric restriction decreases body weights and tumor incidences and increases longevity. The above findings make it likely that many experiments that have been interpreted to demonstrate radiation-induced transgenerational carcinogenesis have instead merely illustrated a confounding effect of extensive induced dominant lethality. That is, because of induced dominant lethality, experimental groups contain heavier mice or rats, which accordingly develop more spontaneous tumors at a faster rate than control groups, with the increased tumor rates having nothing to do with induction of dominant tumor mutations. Our findings prompt suggestions as to possible modifications in the analysis and experimental design of such experiments.

We reason that a coordinated, not independent, action of both conserved and non-conserved residues determine enzymatic activity and specificity. Here, we present a surface patch ranking (SPR) method for in silico discovery of substrate specificity-determining residue clusters by exploring both sequence conservation and correlated mutations. As case studies we apply SPR to several highly homologous enzymatic protein pairs, such as guanylyl versus adenylyl cyclases, lactate versus malate dehydrogenases, and trypsin versus chymotrypsin. Without using experimental data, we predict several single and multi-residue clusters that are consistent with previous mutagenesis experimental results. Most single-residue clusters are directly involved in enzyme-substrate interactions, whereas multi-residue clusters are vital for domain-domain and regulator-enzyme interactions, indicating their complementary role in specificity determination. These results demonstrate that SPR may help the selection of target residues for mutagenesis experiments and, thus, focus rational drug design, protein engineering, and functional annotation to the relevant regions of a protein.

Standard enthalpies of formation of thorite and huttonite are reported for the first time and are -2117.6+ or -4.2 kJ/mol and -2110.9+ or -4.7 kJ/mol, respectively. Based on our measurements, thorite and huttonite are metastable relative to SiO (sub 2) (quartz) and ThO (sub 2) (thorianite) at standard conditions, but are presumably stabilized at high temperature by the entropy contribution. Based on the measured enthalpy of the thorite-huttonite phase transition of 6.7+ or -2.5 kJ/mol, a dP/dT slope for the transformation was calculated as -1.21+ or -0.45 MPa/K.

Understanding of impacts of no-till and traditional agricultural practices on the mechanical properties of aggregates is fundamental to soil management. This study assessed the tensile strength (TS), bulk density (rho (sub agg) ), soil moisture retention (SMR), and soil organic C (SOC) concentration of soil aggregates and determined the interrelationships among aggregate properties under long-term moldboard plow (MP), chisel plow (CP), disk with beef cattle manure (DM), no-till with beef cattle manure (NTM), no-till without beef cattle manure (NT), pasture, and forest systems in the North Appalachian region. Properties were determined on 1- to 8-mm aggregates from 0- to 30-cm soil depth. The TS and SMR (0 to -333 kPa) in NTM were higher than those in MP and CP (P 35 yr) no-till combined with manuring improved the aggregate properties contrasting with conventionally cultivated systems.

Single crystals of the minerals were pre-annealed in a CO (sub 2) atmosphere for 24 h. The crystals were encapsulated in platinum, the capsules were evacuated, and CO (sub 2) was transferred to the capsule before welding. The CO (sub 2) had the isotopic composition of approximately 98% (super 13) C and 90% (super 18) O. The samples were heated in a muffle furnace for periods ranging from 61 to 74 d. After experimentation, the (super 18) O/( (super 18) O + (super 16) O) ratio was measured on a cleavage surface by secondary ionization mass spectrometry depth profiling. The exchanged profile in dolomite is 75 to 200 nm thick, indicating diffusivities of 1.05 X 10 (super -17) cm (super 2) /s at 600 degrees C to 9.33 X 10 (super -19) cm (super 2) /s at 500 degrees C. Profiles in magnesite are much shallower, 25-40 nm at 500 and 600 degrees C, respectively. The data are noisy and give values of D of 2.8-3.1 X 10 (super -19) for both temperatures. The diffusivities of O in dolomite are similar to those in calcite, measured previously, but are about an order of magnitude greater than that in magnesite.

Perchlorate and nitrate both are formed in the atmosphere as a result of photochemical reactions that impart unusual isotopic characteristics including mass-independent signatures. Both species are unusually abundant in the hyper-arid Atacama Desert in Chile because of natural accumulation of salts, and both are present in sodium nitrate fertilizers imported from Chile. Both compounds also have well-known anthropogenic sources that overwhelm the natural sources locally. Nitrate stable isotopes ( (super 15) N: (super 14) N and (super 18) O: (super 17) O: (super 16) O) can provide information about the relative importance of different sources such as atmospheric deposition, nitrification of natural and anthropogenic sources of nitrogen in soils and fertilizers, or local contamination by waste disposal, but the data from both contaminated and uncontaminated settings commonly indicate substantial biogeochemical modification. Perchlorate may be present in groundwater as a result of various combinations of (1) natural production with natural distribution (e.g., local precipitation concentrated by evapotranspiration), (2) natural production with artificial distribution (e.g., application of Chilean nitrate fertilizers containing perchlorate), or (3) artificial production with artificial distribution (e.g., military and commercial releases of synthetic materials). Comprehensive stable isotope analyses ( (super 37) Cl: (super 35) Cl and (super 18) O: (super 17) O: (super 16) O) of perchlorate from known synthetic and natural sources reveal systematic differences in isotopic characteristics that are related to the formation mechanisms. New isotopic data from several different sites in the Western United States prove that both naturally-produced and synthetic sources of perchlorate are present in groundwater at concentrations exceeding 10 mu g/L. More work is needed on the association between perchlorate, nitrate, and other oxyanions in natural and agricultural settings, and the biogeochemical processes that can affect their isotopic compositions.

To assess the significance of Al-oxalate speciation in geological systems we have measured equilibria of the form Al (super 3+) + nC (sub 2) O (sub 4) (super 2-) = Al(C (sub 2) O (sub 4) ) (sub n) (super 3-2n) n < or =3. Formation constants were measured by potentiometric titration using a hydrogen electrode concentration cell. Measurements were made at 8 temperatures ranging from 5 to 150 degrees C and at ionic strengths ranging from 0.1 mol-kg (super -1) to 1.0 mol-kg (super -1) in aqueous NaCl media. When I=0.6 mol-kg (super -1) , the values of Q (sub 1) , Q (sub 2) , and Q (sub 3) increase from 10 (super 5.33) , 10 (super 9.87) , and 10 (super 14.12) , respectively, at 5 degrees C to 10 (super 7.41) , 10 (super 12.76) , and 10 (super 16.94) , respectively, at 125 degrees C.

Small abiotic and biotic particles, including individual, viable bacterial cells, can be attached to the tip of an AFM cantilever. As the mounted object is moved towards a surface in air or solution with sub-nanometer control, forces in the sub-nanoNewton regime can be measured as a function of particle-collector separation. In conjunction with a mathematical construct capable of utilizing experimentally derived force measurements, such as the Interaction Force Boundary Layer (IFBL) model, sticking efficiencies can be obtained and compared with those estimated from column and field studies, as well as DLVO theoretical models. To date, we have determined sticking efficiencies for 2 micron carboxylated polystyrene microspheres and Enterococcus faecalis cells against a silica glass surface, the latter which simulates course quartz grains. Sticking efficiencies for the bacteria are smaller than those determined from column and field studies in comparable systems; however, sticking efficiencies derived from AFM data and the IFBL model more closely represent field data than those calculated via DLVO models. A comparison with different methods of calculating sticking efficiencies suggests that reversible adhesion may be significant in larger-scale transport studies. Finally, various transmission electron microscope (TEM) sample preparation techniques have been developed to better search for nanoparticles in surface water, groundwater, and drinking water distribution systems, and to determine their role in the transport of toxic heavy metals. For example, Mn- and Fe-oxide nanoparticles and various sulfide nanoparticles, as small as 1.5 nm in diameter and all containing heavy metals, have been discovered in the Clark Fork Superfund Complex in Montana, USA. These nanoparticles are clearly important in transporting heavy metals tens to hundreds of kilometers down hydrologic gradient.

We have constructed a 3D field-scale groundwater flow and multicomponent reactive transport model that incorporates multiple TEAPs obtained from a batch TEAP model which has been successfully formulated and used to simulate laboratory experimental observations. Field-scale simulation is conducted using the reaction system and parameters derived from the batch TEAP model and the conceptual model and hydrologic parameters estimated from the results of pumping tests and water level monitoring and model interpretation of a tracer test conducted in August 2004 for a highly heterogeneous surficial aquifer near Oak Ridge, TN. Preliminary simulations are used to understand field-scale processes and evaluate alternative experimental designs involving injection of ethanol to stimulate microbial reduction of uranium and precipitation of U(IV) minerals.

This involved performing a quantitative analysis of the relationships between program results and selected characteristics of the partnerships as well as soliciting opinion data from partnership representatives regarding the factors related to good performance. The statistical analysis revealed that partnership age and the number of projects per partnership were both positively related to all the results measures tested, by themselves and in the presence of each other. The factors most frequently mentioned by the interviewed partnership representatives as influencing good partnership performance were: general assistance from the Rebuild America representative; open communications among all partners; existence of a 'champion' for the partnership; support from the relevant city or state government; effective marketing to attract new partners; strong community interest; quick return on investment; interaction with other community organizations; and continuity of funding. A full discussion of all study findings can be found in the ORNL Report entitled an examination of Rebuild America partnership accomplishments and the factors influencing them (ORNL/CON-490, Oak Ridge National Laboratory, Oak Ridge, TN).

Gene expression patterns were similar irrespective of which metal ion was used as electron acceptor, with 60% of the differentially expressed genes showing similar induction or repression relative to fumarate-respiring conditions. Several groups of genes exhibited elevated expression levels in the presence of metals, including those encoding putative multidrug efflux transporters, detoxification proteins, extracytoplasmic sigma factors and PAS-domain regulators. Only one of the 42 predicted c-type cytochromes in MR-1, SO3300, displayed significantly elevated transcript levels across all metal-reducing conditions. Genes encoding decaheme cytochromes MtrC and MtrA that were previously linked to the reduction of different forms of Fe(III) and Mn(IV), exhibited only slight decreases in relative mRNA abundances under metal-reducing conditions. In contrast, specific transcriptome responses were displayed to individual non-metal electron acceptors resulting in the identification of unique groups of nitrate-, thiosulfate- and TMAO-induced genes including previously uncharacterized multi-cytochrome gene clusters. Collectively, the gene expression results reflect the fundamental differences between metal and non-metal respiratory pathways of S. oneidensis MR-1, where the coordinate induction of detoxification and stress response genes play a key role in adaptation of this organism under metal-reducing conditions. Moreover, the relative paucity and/or the constitutive nature of genes involved in electron transfer to metals is likely due to the low-specificity and the opportunistic nature of the metal-reducing electron transport pathways.

The discrete lattice topology of the model is based on nacre's unique brick and mortar microarchitecture. The mechanical behavior of each of the bonds in the discrete lattice model is governed by the characteristic modular damage evolution of the organic matrix and the mineral bridges between the aragonite platelets. The numerical results obtained using this simple discrete lattice model are in very good agreement with the previously obtained experimental results, such as nacre's stiffness, tensile strength, and work of fracture. The analysis indicates that nacre's superior toughness is a direct consequence of ductility (maximum shear strain) of the organic matrix in terms of repeated unfolding of protein molecules, and its fracture strength is a result of its ordered brick and mortar architecture with significant overlap of the platelets, and shear strength of the organic matrix.

Comparison of the nationally summarized results with other national datasets shows generally good agreement, usually within 2%, and gives insight into the quality of all the data series. Our extension of the state-by-state emissions estimates back to 1960 reveals patterns of change that are coherent across states and can be related to historic events such as energy crises and federal legislation. Most notable is the changing pattern of coal usage, as coal-producing states produce increasingly more energy (mostly for electricity) for other states so that per capita CO sub(2) emissions diverge for states that import as opposed to those that export electricity. The decline in carbon emissions from petroleum products following the 1970s is also evident. Per capita emissions range over an order of magnitude for the different states. The data suggest that differences in per capita emissions arise from differences in many technological, physical, resource, social, and economic factors. The data presented here and the few correlations briefly noted pose a challenge for trying to use per capita emissions as a measure of equity or to provide mitigation targets.

One way to categorize these effects is by the spatial scale of the cause and the impacts. Roads may be viewed from the perspective of road segments, the road network, or roads within land ownership or political boundaries such as counties. This paper examines the hypothesis that the observable impacts of roads on the environment depend on spatial resolution. To examine this hypothesis, the environmental impacts of vehicles and roads were considered at four scales in west central Georgia in and around Fort Benning: a second-order catchment, a third-order watershed, the entire military installation, and the five-county region including Fort Benning. Impacts from an experimental path made by a tracked vehicle were examined in the catchment. Land-cover changes discerned through remote sensing data over the past three decades were considered at the watershed and installation scales. A regional simulation model was used to project changes in land cover for the five-county region. Together these analyses provide a picture of the how environmental impacts of roads and vehicles can occur at different spatial scales. Following tracked vehicle impact with a D7 bulldozer, total vegetation cover responded quickly, but the plant species recovered differently. Soils were compacted in the top 10 cm and are likely to remain so for some time. Examining the watershed from 1974 to 1999 revealed that conversion from forest to nonforest was highest near unpaved roads and trails. At the installation scale, major roads as well as unpaved roads and trails were associated with most of the conversion from forest to nonforest. For the five-county region, most of the conversion from forest to nonforest is projected to be due to urban spread rather than direct road impacts. The study illustrates the value of examining the effects of roads at several scales of resolution and shows that road impacts in west central Georgia are most important at local to subregional scales. The insights from these analyses led to several questions about resource management at different spatial scales.

The experiments were carried out at ocean depths of 1000-1300 m in Monterey Bay, CA, using a larger injector than that initially employed under remotely operated vehicle control and imaging of the product. Solidlike composite particles comprised of water, solid CO sub(2) hydrate, and liquid CO sub(2) were produced in both studies. In the recent injections, the particles consistently sank at rates of similar to 5 cm s super(-1). The density of the sinking particles suggested that similar to 40% of the injected CO sub(2) was converted to hydrate, while image analysis of the particle shrinking rate indicated a CO sub(2) dissolution rate of 0.76-1.29 mu mol cm super(-2) s super(-1). Plume modeling of the hydrate composite particles suggests that while discrete particles may sink 10-70 m, injections with CO sub(2) mass fluxes of 1-1000 kg s super(-1) would result in sinking plumes 120-1000 m below the injection point.

To explore the rates of C cycling in temperate forest soils, we took advantage of a unique opportunity in the form of an inadvertent stand-level (super 14) C-labeling originating from a local industrial release. A simple density fractionation scheme separated SOM into inter-aggregate particulate organic matter (free light fraction, free LF), particulate organic matter occluded within aggregates (occluded LF), and organic matter that is complexed with minerals to form a dense fraction (dense fraction, DF). Minimal agitation and density separation was used to isolate the free LF. The remaining dense sediment was subjected to physical disruption and sonication followed by density separation to separate it into occluded LF and DF. The occluded LF had higher C concentrations and C:N ratios than the free LF, and the C concentration in both light fractions was ten times that of the DF. As a result, the light fractions together accounted for less than 4% of the soil by weight, but contained 40% of the soil C in the 0-15 cm soil increment. Likewise, the light fractions were less than 1% weight of the 15-30 cm increment, but contained more than 35% of the soil C. The degree of SOM protection in the fractions, as indicated by Delta (super 14) C, was different. In all cases the free LF had the shortest mean residence times. A significant depth by fraction interaction for (super 14) C indicates that the relative importance of aggregation versus organo-mineral interactions for overall C stabilization changes with depth. The rapid incorporation of (super 14) C label into the otherwise depleted DF shows that this organo-mineral fraction comprises highly stable material as well as more recent inputs.

Although their oolitic and pisoidal texture suggests energetic and agitated conditions, their mineralogy seems to require a reducing and stagnant environment. Because of this conflict, they have long been considered diagenetic replacements of precursor iron oxide, chamosite, or carbonate ooids. Coated iron sulfide (CIS) grains from the Ordovician Winnipeg Formation of Saskatchewan, Canada, formed as primary diagenetic precipitates under shallow burial conditions, involving intermittent episodes of tractional reworking, grain abrasion, reburial, and precipitation of further concentric laminae. These iron sulfide grains are found in shallow marine sandstones with indications of episodic wave reworking, and indicate sufficient organic-matter burial to promote reducing pore waters and iron sulfide formation. Horizons with strong enrichment of iron sulfide grains (up to 40%) indicate negative net sedimentation to facilitate geochemical "reworking" of iron. CIS grains formed during intervals of maximum sediment starvation, when organic matter was enriched in surface sediments, and rare storm waves intermittently reworked the surface sediment. Alternating laminae of pyrite and marcasite within these grains point to substantial fluctuations in pore-water pH, driven by intermittent oxidation of previously formed iron sulfides. Filamentous and coccoid structures within cortical laminae suggest microbial involvement in lamina formation through providing a growth medium for sulfate-reducing bacteria and potentially a template for mineral growth. Coated iron sulfide grains of the Winnipeg Formation preserve a combined record of condensation, seafloor reworking, fluctuating chemical conditions in the surface sediment, and high surface productivity. This information-rich record is made even more valuable by the fact that the host sediment consists largely of heavily bioturbated monotonous sandstones that could not provide these insights on their own merit.

A series of column experiments was conducted to evaluate the effect of different arrangements of electrodes and ZVI barriers in the column on the TCE removal capacity (RC). In twelve different combinations of ZVI and/or DC application in the test columns, the rate of reductive dechlorination of TCE was improved up to six times with simultaneous application of ZVI and DC compared to that using ZVI only. The most effective arrangement of electrode and ZVI for TCE removal was the column set with ZVI and a cathode installed at the down gradient. Based on the electrokinetic study for the column systems with only DC input, single acid front movement could explain different RCs. An enhanced dechlorination rate of TCE using E2PRB systems, compared to a conventional PRB system, was observed, and is considered to be attributed to more electron sources: (1) external DC, (2) electrolysis of water, (3) oxidation of ZVI, (4) oxidation of dissolved Fe super(2+), (5) oxidation of molecular hydrogen at the cathode, and (6) oxidation of Fe super(2+) in mineral precipitates. Each of these electron sources was evaluated for their potential influencing the TCE RC through the electron competition model and energy consumption. A strong correlation between the quantity of electrons generated, RC, and the energy-effectiveness was found.

At the Savannah River Site, larger, porous particles with monosodium titanate were desired for continuous column operations. The internal gelation process was used to make hydrous titanium oxide microspheres with 32 and 50 wt% monosodium titanate. With actual supernatant, the microspheres with 50 wt% monosodium titanate produced average batch distribution coefficients of 35,000 mL/g for plutonium and 99,000 mL/g for strontium. These microspheres were tested using a simulant and a flow rate of 5.3 bed volumes per hour. The plutonium removal dropped from 99% to 94% while the strontium removal remained nearly 100%. The microspheres exhibited good flow performance and no particle degradation.

The ionic liquids used in this study were 1-butyl-3-methylimidazolium bistrifluoromethanesulfonylimide, 1-hexyl-3-methylimidazolium bistrifluoromethanesulfonylimide, 1-octyl-3-methylimidazolium bistrifluoromethanesulfonylimide, 1-butyl-3-methylimidazolium hexafluorophosphate, trihexyltetradecylphosphonium bistrifluoromethanesulfonylimide, 1-butyl-1-methyl-pyrrolidinium bistrifluoromethanesulfonylimide, trihexyltetradecylphosphonium dodecylbenzenesulfonate, tributyltetradecylphosphonium dodecylbenzenesulfonate, and trihexyltetradecylphosphonium methanesulfonate. Sensitivity of the distribution coefficients to salinity, temperature, concentration, and pH was investigated. Partitioning into the ionic liquid varied considerably. Acetic acid did not significantly partition into the ionic liquid phase, except for the sulfonate-anion ionic liquids. The solubility of hexanoic acid in the ionic liquids was significant, where uptake of the protonated form from aqueous solution was observed for all of the ionic liquids studied. Other organics also showed high distribution coefficients, up to several hundred in the case of toluene and 1-nonanol. The distribution coefficients for toluene, 1-nonanol, cyclohexanone, and hexanoic acid were independent of ionic liquid-to-water ratio over the range from 0.02 to 1.0. The ionic liquids showed a large capacity for some organics, with solubilities measured above 100 g times L super(-1). Regeneration of the ionic liquids by rinsing and heating was studied, with mixed success. These experiments show that certain hydrophobic ionic liquids do have an affinity for organic contaminants in aqueous solution. However, practical application of the ionic liquids tested for detection or removal of selected water-soluble organics from the aqueous waste streams appears to be limited by the small, but significant, solubility of the ionic liquids in the aqueous phase and by difficulty in solvent regeneration. Further work aimed at determination of ionic liquids that dissolve target compounds and are nonhazardous and less soluble in aqueous solutions is recommended.

In the mouse, where the chromosomal deletion coverage is far less extensive than that in Drosophila, substantial coverage of the genome with deletions is strongly desirable. This article reports the generation of three deletion complexes in the distal part of mouse Chromosome (Chr) 15. Chromosomal deletions were efficiently induced by X rays in embryonic stem (ES) cells around the Otoconin 90 (Oc90), SRY-box-containing gene 10 (Sox10), and carnitine palmitoyltransferase 1b (Cpt1b) loci. Deletions encompassing the Oc90 and Sox10 loci were transmitted to the offspring of the chimeric mice that were generated from deletion-bearing ES cells. Whereas deletion complexes encompassing the Sox10 and the Cpt1b loci overlap each other, no overlap of the Oc90 complex with the Sox10 complex was found, possibly indicating the existence of a haploinsufficient gene located between Oc90 and Sox10. Deletion frequency and size induced by X rays depend on the selective locus, possibly reflecting the existence of haplolethal genes in the vicinity of these loci that yield fewer and smaller deletions.

Scenarios for the year 2100 included elevated [CO sub(2)] and [O sub(3)] (+385 ppm and +20 ppb, respectively), warming (+4 degree C), and increased winter precipitation (+20% November-March). Simulations were run with and without adjustments for experimentally observed physiological and biomass adjustments. Initial simplistic model runs for single-factor changes in CO sub(2) and temperature predicted substantial increases (+191% or 508 g C m super(-2) yr super(-1)) or decreases (-206% or -549 g C m super(-2) yr super(-1)), respectively, in mean annual net ecosystem carbon exchange (NEE sub(a) approximately 266 plus or minus 23 g C m super(-2) yr super(-1) from 1993 to 2003). Conversely, single-factor changes in precipitation or O sub(3) had comparatively small effects on NEE sub(a) (0% and -35%, respectively). The combined influence of all four environmental changes yielded a 29% reduction in mean annual NEE sub(a). These results suggested that future CO sub(2)-induced enhancements of gross photosynthesis would be largely offset by temperature-induced increases in respiration, exacerbation of water deficits, and O sub(3)-induced reductions in photosynthesis. However, when experimentally observed physiological adjustments were included in the simulations (e.g. acclimation of leaf respiration to warming), the combined influence of the year 2100 scenario resulted in a 20% increase in NEE sub(a) not a decrease. Consistent with the annual model's predictions, simulations with a forest succession model run for gradually changing conditions from 2000 to 2100 indicated an 11% increase in stand wood biomass in the future compared with current conditions. These model-based analyses identify critical areas of uncertainty for multivariate predictions of future ecosystem response, and underscore the importance of long term field experiments for the evaluation of acclimation and growth under complex environmental scenarios.

As a result, natural or anthropogenic disturbance of upland soil and vegetation can affect instream processes. The Fort Benning Military Installation (near Columbus, Georgia) exhibits a wide range of upland disturbance levels because of spatial variability in the intensity of military training. This gradient of disturbance was used to investigate the effect of upland soil and vegetation disturbance on rates of stream metabolism (ecosystem respiration rate [ER] and gross primary production rate [GPP]). Stream metabolism was measured using an open-system, single-station approach. All streams were net heterotrophic during all seasons. ER was highest in winter and spring and lowest in summer and autumn. ER was negatively correlated with catchment disturbance level in winter, spring, and summer, but not in autumn. ER was positively correlated with abundance of coarse woody debris, but not significantly related to % benthic organic matter. GPP was low in all streams and generally not significantly correlated with disturbance level. Our results suggest that the generally intact riparian zones of these streams were not sufficient to protect them from the effect of upland disturbance, and they emphasize the role of the entire catchment in determining stream structure and function.

To determine what length of oligonucleotide is a better alternative to PCR-generated probes, the performance of oligonucleotide probes was systematically compared to that of their PCR-generated counterparts for 96 genes from Shewanella oneidensis MR-1 in terms of overall signal intensity, numbers of genes detected, specificity, sensitivity, and differential gene expression under experimental conditions. Hybridizations conducted at 42 degree C, 45 degree C, 50 degree C, and 60 degree C indicated that good sensitivities were obtained at 45 degree C for oligonucleotide probes in the presence of 50% formamide, under which conditions specific signals were detected by both PCR and oligonucleotide probes. Signal intensity increased as the length of the oligonucleotide probe increased, and the 70-mer oligonucleotide probes produced signal intensities similar to the intensities obtained with the PCR probes and detected numbers of open reading frames similar to the numbers detected with the PCR probes. PCR amplicon, 70-mer, 60-mer, and 50-mer arrays had detection sensitivities of 5.0, 25, 100, and 100 ng of genomic DNA, which were equivalent to approximately 1.9 x 10 super(6), 9.2 x 10 super(6), 3.7 x 10 super(7), and 3.7 x 10 super(7) copies, respectively, when the array was hybridized with genomic DNA. To evaluate differential gene expression under experimental conditions, S. oneidensis MR-1 cells were exposed to low- or high-pH conditions for 30 and 60 min, and the transcriptional profiles detected by oligonucleotide probes (50-mer, 60-mer, and 70-mer) were closely correlated with those detected by the PCR probes. The results demonstrated that 70-mer oligonucleotides can provide the performance most comparable to the performance obtained with PCR-generated probes.

A large portion of this carbon is in the form of gaseous CO sub(2), and approximately 30% of this CO sub(2) comes from fossil fuel power plants. In addition to rising levels of atmospheric CO sub(2), the earth's temperature is increasing. Since CO sub(2) can act as a trap for heat (similar to the glass in a greenhouse), reduction of CO sub(2) emissions is an important area of research. Separation and sequestration of CO sub(2) are near-term goals for emissions reduction. Better fuel efficiency (in power production, transportation, and other areas) can be considered a mid-term goal. An acceptable long-term goal for reducing emissions is using alternate power sources such as nuclear, solar, and wind power. Because separation and sequestration are short-term goals, they are critical and challenging steps for researchers. Methods that are reviewed in this paper include absorption using solvents or solid sorbents, pressure- and temperature-swing adsorption using various solid sorbents, cryogenic distillation, membranes, and several novel and emerging technologies. Upon completion of this review, it was concluded that the most promising current method for CO sub(2) separation is liquid absorption using monoethanolamine (MEA). While this method is currently most promising, the development of ceramic and metallic membranes for membrane diffusion should produce membranes significantly more efficient at separation than liquid absorption. The other methods investigated in this report are either too new for comparison or appear unlikely to experience significant changes to make them desirable for implementation.

AN - 68616834; 16180137 AB - We have used the new high-throughput mutation-scanning technique temperature-gradient capillary electrophoresis (TGCE) for the identification of point mutations induced by N-ethyl-N-nitrosourea (ENU) in the mouse genome. TGCE detects the presence of heteroduplex molecules formed between a wild-type gene segment and the corresponding homologous segment containing an induced mutation or a naturally occurring single nucleotide polymorphism (SNP). Partially denatured heteroduplex molecules are resolved from homoduplexes by virtue of their differential mobilities during capillary electrophoresis conducted in a finely controlled temperature gradient. Simultaneous heteroduplex analysis of 96 amplicons ranging from 150 to 600 bp in size is achieved in approximately 45 min without the need for predetermining the melting profile of each fragment. Initially, we exploited known mouse mutations to develop TGCE protocols for analyzing unpurified PCR samples amplified from crude tail-DNA preparations. TGCE was then applied to the rapid identification of three new ENU-induced mutations recovered from regional mutagenesis screens of a segment of mouse Chromosome 7. Enzyme assays and quantitative reverse transcription-PCR (qRT-PCR) methods validated these new mutations. Our data demonstrate that rapid mutation scanning with TGCE, followed by sequence verification only of detected positives, is an efficient approach to the identification of point mutations in the mouse genome.

AN - 68522702; 16051393 AB - Geochemical and mineralogical changes were evaluated at a field Fe0-PRB at the Oak Ridge Y-12 site concerning operation performance during the treatment of U in high NO3- groundwater. In the 5-year study period, the Fe0 remained reactive as shown in pore-water monitoring data, where increases in pH and the removal of certain ionic species persisted. However, coring revealed varying degrees of cementation. After 3.8-year treatment, porosity reduction of up to 41.7% was obtained from mineralogical analysis on core samples collected at the upgradient gravel-Fe0 interface. Elsewhere, Fe0 filings were loose with some cementation. Fe0 corrosion and pore volume reduction at this site are more severe due to the presence of NO3- at a high level. Tracer tests indicate that hydraulic performance deteriorated: the flow distribution was heterogeneous and under the influence of interfacial cementation a large portion of water was diverted around the Fe0 and transported outside the PRB. Based on the equilibrium reductions of NO3- and SO4(2-) by Fe0 and mineral precipitation, geochemical modeling predicted a maximum of 49% porosity loss for 5 years of operation. Additionally, modeling showed a spatial distribution of mineral precipitate volumes, with the maximum advancing from the interface toward downgradient with time. This study suggests that water quality monitoring, coupled with hydraulic monitoring and geochemical modeling, can provide a low-cost method for assessing PRB performance.

However, studies have not been performed for examining the retardation of VOCs, based on quantitative analyses of processes contributing to retardation as the function of water content during gas flow through unsaturated soils. No investigations have evaluated whether different factors that contribute to VOC retardation during gas transport have an additive effect, such that the sum of different effects can be used to predict overall transport velocity. A series of gas transport experiments was conducted in a soil column over a range of water contents, using a soil with low organic carbon content (approximately 0.1%), and tetrachloroethene (PCE) and 1,1,1-trichloroethane (TCA) as representative VOCs. Three phase-partitioning processes (partitioning into soil water, adsorption at the soil particles, adsorption at the air-water interface) were evaluated independently. The sum of retardation effects from these processes was then compared with the observed VOC retardation factors. Measured retardation factors for PCE and TCA were in good agreement with those predicted over the range of water contents (0.02-0.24) examined in this study, supporting the additive nature of different phase-partitioning processes for the gas transport of VOCs in soils. Also, the relative contribution of each phase-partitioning process to the total retardation of VOCs during gas transport was a strong function of water content.

The adsorption of Al3+, Cu2+, and para-chlorophenol, respectively, from water decreased as a function of increasing surface oxygen content of the carbons. When the carbon of lowest surface oxygen content was oxidized with ozone to impart a surface oxygen content comparable to that of a carbon with a much higher phosphate level, adsorption of Al3+, Cu2+, and para-chlorophenol from water decreased proportionally. The increase in polarity of the carbon surface was accompanied by a decrease in pH and appeared to be the dominant factor with respect to the adsorption of the target species from water.

The study was conducted at the U.S. Army's Fort Benning installation where vegetation loss and high rates of erosion from intensely used training areas and unpaved roads have resulted in extensive sedimentation in some streams. Diurnal profiles of dissolved oxygen were measured in 10 second-order streams draining catchments which exhibited a range of disturbance levels. Rates of gross primary production (GPP) and total ecosystem respiration (R) per unit surface area were determined for each stream using the single-station diurnal dissolved oxygen change method with direct measurement of air-water oxygen exchange rates. The daily amplitude of the diurnal dissolved oxygen deficit profile was highly correlated with daily rates of GPP, and multiplying the daily amplitude by average stream depth to account for differences in water volume did not improve the correlation. The daily maximum dissolved oxygen deficit was highly correlated with daily rates of R, and multiplying by average stream depth improved the correlation. In general, these indicators of stream metabolism declined sharply with increasing catchment disturbance level, although the indicators of R showed a more consistent relationship with disturbance level than those of GPP. Our results show that the daily amplitude and maximum value of diurnal dissolved oxygen deficit profiles are good indicators of reach-scale rates of metabolism and the effects of catchment-scale disturbance on these metabolism rates. At Fort Benning, and presumably at other military installations, they are useful tools for evaluating trends in impacts from military training or rates of recovery following restoration activities.

A high incidence of cancer in the Mayak workers has been related to the level of exposure to plutonium, but uncertainties in tissue doses have hampered development of dose-risk relationships. As part of an effort to improve dose estimates for these workers, the systemic biokinetic model for plutonium currently recommended by the International Commission on Radiological Protection (ICRP) has been modified to reflect recently developed data and facilitate interpretation of case-specific information. This paper describes the proposed model and discusses its implications for dose reconstruction for the Mayak workers.

AN - 68448019; 16082956 AB - Although humic substances occur ubiquitously in soil and groundwater, their effect on the biological reduction of uranium(VI) and subsequent reoxidation of U(IV) is poorly understood. This study investigated the role of humics in enhancing the bioreduction of U(VI) in laboratory kinetic studies, in field push-pull tests, and in the presence or absence of metal ions such as Ca2+ and Ni2+, which are known to inhibit the biological reduction of U(VI). Results from laboratory experiments indicate that, under strict anaerobic conditions, the presence of humic materials enhanced the U(VI) reduction rates (up to 10-fold) and alleviated the toxicity effect of Ni2+ on microorganisms. Humic acid was found to be more effective than fulvic acid in enhancing the reduction of U(VI). Such an enhancement effect is attributed to the ability of these humics in facilitating electron-transfer reactions and/or in complexing Ca2+ and Ni2+ ions. Similarly, field push-pull tests demonstrated a substantially increased rate of U(VI) reduction when humic acid was introduced into the site groundwater. However, humics were also found to form complexes with reduced U(IV) and increased the oxidation of U(IV) (when exposed to oxygen) with an oxidation halflife on the order of a few minutes. Both of these processes render uranium soluble and potentially mobile in groundwater, depending on site-specific and dynamic geochemical conditions. Future studies must address the stability and retention of reduced U(IV) under realistic field conditions (e.g., in the presence of dissolved oxygen and low concentrations of complexing organics).

AN - 68427553; 16053082 AB - The bioreduction of soluble uranium [U(VI)] to sparingly soluble U(IV) species is an attractive remedial technology for contaminated soil and groundwater due to the potential for immobilizing uranium and impeding its migration in subsurface environments. This manuscript describes a column study designed to simulate a three-step strategy proposed for the remediation of a heavily contaminated site at the U.S. Department of Energy's NABIR Field Research Center in Oak Ridge, TN. The soil is contaminated with high concentrations of uranium, aluminum, and nitrate and has a low, highly buffered pH (approximately 3.5). Steps proposed for remediation are (i) flushing to remove nitrate and aluminum, (ii) neutralization to establish pH conditions favorable for biostimulation, and (iii) biostimulation for U(VI) reduction. We simulated this sequence using a packed soil column containing undisturbed aggregates of U(VI)-contaminated saprolite that was flushed with an acidified salt solution (pH 4.0), neutralized with bicarbonate (60 mM), and then biostimulated by adding ethanol. The column was operated anaerobically in a closed-loop recirculation setup. However, during the initial month of biostimulation, ethanol was not utilized, and U(VI) was not reduced. A bacterial culture enriched from the site groundwaterwas subsequently added, and the consumption of ethanol coupled with sulfate reduction immediately ensued. The aqueous concentration of U(VI) initially increased, evidently because of the biological production of carbonate, a ligand known to solubilize uranyl. After approximately 50 days, aqueous U(VI) concentrations rapidly decreased from approximately 17 to <1 mg/L. At the conclusion of the experiment,the presence of reduced solid phase U(IV) was confirmed using X-ray absorption near edge structure spectroscopy. The results indicate that bioreduction to immobilize uranium is potentially feasible at this site; however, the stability of the reduced U(IV) and its potential reoxidation will require further investigation, as do the effects of groundwater chemistry and competitive microbial processes, such as methanogenesis.

It is designed to suppress harmonic noise from a rotor that varies slightly in amplitude, phase, and frequency and that contaminates aeromagnetic data. The filter provides a powerful harmonic noise-suppression tool for data acquired with modern large-dynamic-range recording systems. This three-step approach -- polynomial fitting, bandpass filtering, and rotor-noise synthesis -- significantly reduces rotor noise without altering the spectra of signals of interest. Two steps before hum filtering -- polynomial fitting and bandpass filtering -- are critical to accurately model the weak rotor noise. During rotor-noise synthesis, amplitude, phase, and frequency are determined. Data are processed segment by segment so that there is no limit on the length of data. The segment length changes dynamically along a line based on modeling results. Modeling the rotor noise is stable and efficient. Real-world data examples demonstrate that this method can suppress rotor noise by more than 95% when implemented in an aeromagnetic data-processing flow.

Along the spatial gradient of the stream, levels of contaminants decreased downstream along with improved responses of instream biota at several levels of biological organization. Recovery of the biota in this stream over the 15 year study period is demonstrated by the temporal relationships between levels of decreasing contaminants and the concomitant responses of the periphyton, macroinvertebrate, and fish communities and changes in the various bioindicators of individual fish health. Decreases in contaminants over a temporal scale were followed closely by an improvement in physiological and organismal-level indicators, increases in the diversity of macroinvertebrate and fish communities, and rapid increases in the chlorophyll a biomass and photosynthesis rate of the periphyton community. These results emphasize that field studies designed to assess and evaluate the effectiveness of restoration activities on stream recovery should incorporate a variety of response endpoints ranging from sensitive and short-term responses to long-term but ecological relevant indicators of change. The close spatial and temporal relationships observed between changes in physicochemical factors and positive responses in various components of the stream biota over the 15-year study period suggest a strong cause and effect relationship between remediation activities and stream recovery. Understanding causal relationships and the mechanistic processes between environmental stressors, stress responses of biota, and the recovery process is important in the effective management and restoration of aquatic ecosystems.

I: New Measurements from Six Operating Landfills in Florida AN - 20632554; 6537532 AB - Mercury-bearing material enters municipal landfills from a wide array of sources, including fluorescent lights, batteries, electrical switches, thermometers, and general waste; however, the fate of mercury (Hg) in landfills has not been widely studied. Using automated flux chambers and downwind atmospheric sampling, we quantified the primary pathways of Hg vapor releases to the atmosphere at six municipal landfill operations in Florida. These pathways included landfill gas (LFG) releases from active vent systems, passive emissions from landfill surface covers, and emissions from daily activities at each working face (WF). We spiked the WF at two sites with known Hg sources; these were readily detected downwind, and were used to test our emission modeling approaches. Gaseous elemental mercury (Hg0) was released to the atmosphere at readily detectable rates from all sources measured; rates ranged from similar to 1-10 ng m-2 hr-1 over aged landfill cover, from similar to 8-20 mg/hr from LFG flares (LFG included Hg0 at ug/m3 concentrations), and from similar to 200-400 mg/hr at the WF. These fluxes exceed our earlier published estimates. Attempts to identify specific Hg sources in excavated and sorted waste indicated few readily identifiable sources; because of effective mixing and diffusion of Hg0, the entire waste mass acts as a source. We estimate that atmospheric Hg releases from municipal landfill operations in the state of Florida are on the order of 10-50 kg/yr, substantially larger than our original estimates, but still a small fraction of current overall anthropogenic losses.

II: Potential Losses of Airborne Mercury before Landfill AN - 20629745; 6537533 AB - Waste distribution and compaction at the working face of municipal waste landfills releases mercury vapor (Hg0) to the atmosphere, as does the flaring of landfill gas. Waste storage and processing before its addition to the landfill also has the potential to release Hg0 to the air if it is initially present or formed by chemical reduction of HgII to Hg0 within collected waste. We measured the release of Hg vapor to the atmosphere during dumpster and transfer station activities and waste storage before landfilling at a municipal landfill operation in central Florida. We also quantified the potential contribution of specific Hg-bearing wastes, including mercury (Hg) thermometers and fluorescent bulbs, and searched for primary Hg sources in sorted wastes at three different landfills. Surprisingly large fluxes were estimated for Hg losses at transfer facilities ( similar to 100 mg/hr) and from dumpsters in the field ( similar to 30 mg/hr for 1000 dumpsters), suggesting that Hg emissions occurring before landfilling may constitute a significant fraction of the total emission from the disposal/landfill cycle and a need for more measurements on these sources. Reducing conditions of landfill burial were obviously not needed to generate strong Hg0 signals, indicating that much of the Hg was already present in a metallic (Hg0) form. Attempts to identify specific Hg sources in excavated and sorted waste indicated few readily identifiable sources; because of effective mixing and diffusion of Hg0, the entire waste mass acts as a source. Broken fluorescent bulbs and thermometers in dumpsters emitted Hg0 at 10 to similar to 100 ug/hr and continued to act as near constant sources for several days.

Rare survivors can maintain telomere length through either activation of telomerase or recombination-based telomere lengthening, and thus proliferate indefinitely. We have explored the possibility that telomeres may be maintained through telomere sister chromatid exchange (T-SCE) in murine telomere reverse transcriptase-deficient (mTert super(-/-)) splenocytes and ES cells. Because telomerase deficiency leads to gradual loss of telomeric DNA in mTert super(-/-) splenocytes and ES cells and eventually to chromosomes with telomere signal-free ends (SFEs), we examined these cell types for evidence of sister chromatid exchange at telomeres, and observed an increase in T-SCEs only in a subset of mTert super(-/-) splenocytes or ES cells that possessed multiple SFEs. Furthermore, T-SCEs were more often detected in ES cells than in splenocytes that harbored a similar frequency of SFEs. In mTert heterozygous (mTert super(+) super(/) super(-)) ES cells or splenocytes, which are known to exhibit a decrease in average telomere length but no SFEs, no increase in T-SCE was observed. In addition to T-SCE, other genomic rearrangements (i.e., SCE) were also significantly increased in mTert super(-/-) ES cells possessing critically short telomeres, but not in splenocytes. Our results suggest that animals and cell culture differ in their ability to carry out genomic rearrangements as a means of maintaining telomere integrity when telomeres become critically shortened.

Biomolecule-containing particles were laboratory-generated and passed through a heated region containing a solution of matrix in equilibrium with the gas phase. Passage into a cooler region created a supersaturation, resulting in rapid deposition of the matrix vapor onto the biomolecule-containing particles, whereupon they were sampled into the inlet of our spectrometer. The coated particles were collimated and individually sized by light-scattering-based time-of-flight. When the sized particle reached the center of the ion trap, it was irradiated with a focused 266-nm laser, and the resulting ions were mass-analyzed. Mass spectra of leucine enkephalin, bradykinin, substance P, and polylysine-containing particles were determined with attomole sensitivity. Structural information of the peptides contained in an individual particle was obtained by tandem mass spectrometry.

We have demonstrated, for the first time, the measurement of H sub(2)O sub(2) production from cigarette smoke without prior separation of the sample. Cigarettes were tested on a commercial smoking machine, such that the whole smoke or gas vapor phase was bubbled through phosphate buffered saline solution at pH 7.4. Aliquots of these solutions were analyzed using an Amplex Red/horseradish peroxidase fluorimetric assay that required only a 2 minute incubation time, facilitating the rapid, facile collection of data. Catalase was used to demonstrate the selectivity and specificity of the assay for H sub(2)O sub(2) in the complex smoke matrix. We measured similar to 7-8 mu M H sub(2)O sub(2) from two reference cigarettes (i.e., 1R4F and 2R4F). We also observed 9x more H sub(2)O sub(2) from whole smoke bubbled samples compared to the gas vapor phase, indicating that the major constituent(s) responsible for H sub(2)O sub(2) formation reside in the particulate phase of cigarette smoke. Aqueous solutions of hydroquinone and catechol, both of which are particulate phase constituents of cigarette smoke, generated no H sub(2)O sub(2) even though they are free radical precursors involved in the production of reactive oxygen species in the smoke matrix.

Sticking efficiencies were calculated in solutions of varying pH and ionic strength and related to maximum distances of transport through a hypothetical soil block using colloid filtration theory. AFM measurements show that the repulsive and attractive forces between E. faecalis cells and a glass surface are a function of ionic strength but are less sensitive to changes in solution pH. Zeta ()-potential measurements of the cells and glass surfaces correlate with these trends. Calculated DLVO energy profiles predict much greater sensitivity to changing solution chemistry. Sticking efficiencies derived from AFM measurements range from 9.6 x 10 super(-17) to 1 in solutions of low ionic strength (IS) and from 2.6 x 10 super(-33) to 1 at higher IS. Corresponding a values determined from DLVO theory are essentially zero in all tested solutions. Sticking efficiencies calculated in this study are smaller than values determined from column and field studies in similar systems; however, a derived from AFM data and the IFBL model more closely represent field data than do values calculated from DLVO energy values. A comparison with different methods of calculating a suggests that reversible adhesion may be significant in column-scale transport studies. , Associate editor: Jeremy B.

Spatial population models typically simulate birth, death, and migration on an input map that describes habitat. Typically, only a single "reference" map is available, but we can imagine that a collection of other, slightly different, maps could be drawn to represent a particular species' habitat. As a first approximation, our approach assumes that spatial uncertainty (i.e. the variation among values assigned to a location by such a collection of maps) is constrained by characteristics of the reference map, regardless of how the map was produced. Our approach produces lower levels of uncertainty than alternative methods used in landscape ecology because we condition our alternative landscapes on local properties of the reference map. Simulated spatial uncertainty was higher near the borders of patches. Consequently, average uncertainty was highest for reference maps with equal proportions of suitable and unsuitable habitat, and no spatial autocorrelation. We used two population viability models to evaluate the ecological consequences of spatial uncertainty for landscapes with different properties. Spatial uncertainty produced larger variation among predictions of a spatially explicit model than those of a spatially implicit model. Spatially explicit model predictions of final female population size varied most among landscapes with enough clustered habitat to allow persistence. In contrast, predictions of population growth rate varied most among landscapes with only enough clustered habitat to support a small population, i.e. near a spatially mediated extinction threshold. We conclude that spatial uncertainty has the greatest effect on persistence when the amount and arrangement of suitable habitat are such that habitat capacity is near the minimum required for persistence.

Tolerance intervals are simply confidence intervals based on percentiles, and they allow selection of acceptable limits (referred to as tolerance limits) and a desired level of statistical confidence for a metric distribution (e.g., of a reference population). We used benthic macroinvertebrate community data from several long-term monitoring projects for streams on the US Department of Energy's Oak Ridge Reservation in eastern Tennessee, USA, for the demonstration. We focused on 3 benthic macroinvertebrate community metrics: density, total taxonomic richness, and taxonomic richness of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa. Tolerance intervals yielded less restrictive thresholds than those produced by simple percentiles because the former approach includes variation of the reference data, whereas percentiles are distribution-free. The less restrictive thresholds produced by tolerance intervals will decrease the frequency with which metric values from test sites will be classified as unacceptable because data variation is included, but thresholds calculated using the tolerance interval approach may be better suited for studies that require a greater level of statistical rigor than routine monitoring or general screening surveys (e.g., biocriteria, environmental impact assessments). Conversely, approaches that use simple percentiles may be more appropriate for screening studies. Greater accuracy of tolerance limits can be achieved by increasing sample size, reducing variation (e.g., removing outliers, data transformation), and including data that incorporate both spatial and temporal variation. However, alternative approaches should be used if the data are not normally distributed. Tolerance limits can be adjusted easily to achieve the level of environmental protection desired or required, while providing a level of statistical confidence in derived thresholds. For this reason, a tolerance interval approach should be considered seriously, particularly if the study objectives require a known level of statistical certainty.

Aglime includes crushed limestone (CaCO sub(3)) and crushed dolomite (MgCa(CO sub(3)) sub(2)). Following the supposition by the Intergovernmental Panel on Climate Change (IPCC) that all C in aglime is eventually released as CO sub(2) to the atmosphere, the U.S. EPA estimated that 9 Tg (Teragram = 10 super(12) g = 10 super(6) metric tonne) CO sub(2) was emitted from an approximate 20 Tg of applied aglime in 2001. A review of historic data on aglime production and use indicates that 30 Tg may better represent the annual U.S. consumption of aglime. More importantly, our review of terrestrial and ocean C dynamics indicates that it is unlikely that all C from aglime is released to the atmosphere following application to soils. On the contrary, the primary pathway for aglime dissolution is reaction with carbonic acid (H sub(2)CO sub(3)) which results in uptake of CO sub(2). Depending on soil pH and nitrogen fertilizer use, a fraction of aglime may react with strong acid sources such as nitric acid (HNO sub(3)), thereby releasing CO sub(2). Data on soil leaching and river transport of calcium (Ca super(2+)) and bicarbonate (HCO sub(3) super(-)) suggest that a significant portion of dissolved aglime constituents may leach through the soil and be transported by rivers to the ocean. Much of the fraction transported to the ocean will precipitate as CaCO sub(3). Bicarbonate remaining in the soil profile is expected to release CO sub(2) following re-acidification of the soil over time. Our analysis indicates that net CO sub(2) emissions from the application of aglime is 0.059 Mg C per Mg limestone and 0.064 Mg C per Mg dolomite. This is in contrast to IPCC estimates of 0.12 and 0.13 Mg C per Mg limestone and dolomite, respectively. Based on our best estimate, the application of 20-30 Tg of aglime in the U.S., consisting of 80% limestone and 20% dolomite, would have resulted in a net 4.4-6.6 Tg CO sub(2) emissions in 2001.

The reaction, O sub(3)+Hg-HgO+O sub(2), is considered to be an unlikely pathway for atmospheric conditions. Considerations given here suggest that the reaction may occur with initial formation of a metastable HgO sub(3) molecule that in laboratory experiments is the source of the HgO product observed to accumulate on the walls of the reactor (HgO sub(3)-HgO(s)+O sub(2)). Laboratory studies of the gas phase reaction, Hg+OH-HgOH (2), have been reported using relative rate measurements initiated by photodissociation of an organic nitrite in mixtures of Hg vapor with NO, air and various reference hydrocarbons. Computer simulations of this reaction system suggest that the use of reactive reference gases (e.g. cyclohexane) leads to the generation of significant ozone in these NO sub(x) RH-air mixtures, and the resulting O sub(3)-Hg reaction can result in an over-estimate of the rate of reaction (2). Also the apparent rate coefficients for reaction (2) are highly dependent on the assumed rate coefficients of its competitive reactions of dissociation in HgOH-Hg+OH (3), and association of HgOH molecule with other free radicals present in the system: HgOH+X-XHgOH (4); X=OH, HO sub(2), RO, RO sub(2), NO, NO sub(2). Reaction (4) competes successfully with HgOH decomposition for the laboratory conditions employed, and the kinetic measurements relate to the rate determining reaction, Hg+OH-HgOH in this case. However, the use of these laboratory measurements of k sub(2) to determine the extent of Hg removal by OH in the troposphere will greatly over-estimate the importance of Hg removal by this reaction.

This is a new operational system that measures chromatographically separated DOC compounds with a total inorganic/organic carbon analyzer (TCA) interfaced with an isotope ratio mass spectrometer (IRMS), and it represents a significant contribution to analytical technology. Leachate samples were collected from the Trail Road Landfill (TRL) site located about 25 km to the west of the city of Ottawa, Canada. Measurements of Eh, pH, electrical conductivity, dissolved oxygen, total dissolved solids, and temperature were completed at the field site. High performance liquid chromatography (HPLC) was used to separate DOC components into fractions for separate analysis on TCA. The TCA is operated in-line with a Thermo-Finnigan Delta (super Plus) continuous-flow isotope ratio mass spectrometer (CF-IRMS) that oxidises organic carbon to CO (sub 2) for measurement of both concentration, by infrared absorption, and delta (super 13) C. DOC fraction collection was based on the detection of discrete peaks of individual compounds, allowing identification of key peaks, such as acetate, with recoveries of up to 100%. The difference in delta (super 13) C values for leachate acetate (-10.7ppm to -16.9ppm VPDB) and the bulk DOC (-24.7ppm VPDB) can be used to distinguish landfill leachate derived DOC and identify biogeochemical reactions. The enrichment of delta (super 13) C in the acetate suggests that this biologically derived compound has become a substrate for secondary biogeochemical reaction, likely methanogenesis.

The increase of carbon and nitrogen concentrations in the core sediments collected near the mouth of the freshwater river suggested that the anthropogenic eutrophication first started in the 1940s due to the increase of loads caused by the increased population in the drainage area. delta (super 15) N of the sediments also implied that the eutrophication continues to date even after the end of population growth, due presumably to the use of chemical fertilizer. Organic carbon and total nitrogen concentrations showed higher values during the early 19th century than the present in the core sediments collected at the east end of the lake where polyhaline water occasionally flows back. These higher concentrations were attributed to more frequent backflow of polyhaline water.

So far, although we have interesting evidence that there are temporal and spatial age offsets between the algal "alkenone" biomarker used for SST (sea surface temperature) estimates and planktonic foraminifera in regions with high sedimentation rates, less is known about such age offsets in the settings of lower sedimentation. In this study, to investigate the potential of biomarkers as an alternative dating proxy to foraminifera in a low sedimentation rate setting, we measured radiocarbon ages of 17 different lipid biomarkers [fatty acids (FAs), n-alkanes, and alkenones], bulk total organic matter (TOC), and foraminifera from two sections (12-15 cm and 21-24 cm depth) of a surface sediment core in the Northwest Pacific. The sedimentation rate, estimated from the TOC, ranged from 10.5 cm/kyr in the core top to 0.9 cm/kyr in the lower part of the core. The ages of the FAs detected at 12-15 cm depth ranged from 530 yr BP (C (sub 18) ) to 3250 yr BP (C (sub 28) ). The (super 14) C analysis of the FAs could be divided into two groups: FAs (C (sub 16) , C (sub 18) ) derived from marine organisms and those (C (sub 24) , C (sub 26) , C (sub 28) ) derived from terrestrial higher plants. The high molecular weight (HMW) FAs' ages were older [2550 yr BP (C (sub 24) ) to 3250 yr BP (C (sub 28) )] than those of the low molecular weight (LMW) FAs [530 yr BP (C (sub 18) ) to 1820 yr BP (C (sub 16) )]. At 21-24 cm depth, the alkenone ages were 7100-7300 yr younger than those of the planktonic foraminifera. In this horizon, the alkenone (super 14) C age (7500 yr BP) and the alkenone-estimated SST (15.3 degrees C) suggest that these alkenones were produced in this region during the Holocene. The alkenone (super 14) C age was also in good agreement with those of the LMW FAs (C (sub 14) , iC (sub 15) , aiC (sub 15) , C (sub 16) , and C (sub 18:1) ) derived from marine plankton and bacteria. Similarly, the TOC age was 5700 yr younger than that of the planktonic foraminifera. These age differences are large compared with those estimated for the horizon at 12-15 cm depth, which was characterized by a relatively higher sedimentation rate. These trends between ages of alkenones, TOC, and planktonic foraminifera are not comparable to the results from sites with high sedimentation rates, such as the Benguella upwelling system [Mollenhauer, G., Eglinton, T.I., Ohkouchi, N., Schneider, R.R., Muller, P.J., Grootes, P.M., et al., 2003. Asynchronous alkenone and foraminifera records from the Benguela upwelling system. Geochim. Cosmochim. Acta 67, 2157-2171] or the Bermuda Rise drift deposit [Ohkouchi, N., Eglinton, T.I., Keigwin, L.D., Hayes, J.M., 2002. Spatial temporal offsets between proxy records in a sediment drift. Science 289, 1224-1227], which are significantly different sedimentary settings from our site. The radiocarbon results from these high sedimentation rate regions suggest that the alkenones are several thousand years older than the coexisting planktonic foraminifera. On the other hand, the age offsets between alkenones and planktonic foraminifera at our site are larger than those from the other sites, and the alkenones are younger than the planktonic foraminifera.

Both [CH (sub 4) ] and delta (super 13) CH (sub 4) showed strong vertical stratifications, but with significant diurnal variations in their intracanopy and above-canopy gradients. The diurnal variations were mainly influenced by atmospheric stability under flooded conditions and by soil temperature under drained conditions, respectively. With the disappearance of floodwater, delta (super 13) CH (sub 4) profiles showed a distinct transition from higher values (-56.1 ppm to -46.0 ppm) to lower values (-68.9 ppm to -47.1 ppm). At the peak emission of CH (sub 4) upon drainage, CH (sub 4) in the canopy air space showed an identical isotopic composition (-70.1 ppm) to CH (sub 4) stored in the soil. CH (sub 4) in retarded flushes showed irregular vertical distributions of delta (super 13) CH (sub 4) , implying varying degrees of the oxidation of CH (sub 4) released. The results clearly indicate that floodwater drainage initially brings about release of less-oxidized CH (sub 4) into the atmosphere in a large quantity. Good linear relationships were found between 1/[CH (sub 4) ] and the corresponding delta (super 13) CH (sub 4) until the peak emission period. However, the net ecosystem delta (super 13) CH (sub 4) (delta (sub E) ), estimated for each sampling time, showed large fluctuations during the day, and was lower than expected. delta (sub E) estimated on a daily scale was -64.2 ppm, -77.8 ppm, and -64.5 ppm for flooded, transient, and drained conditions, respectively.

Human and domesticated and wild animals bone collagen samples found in Ajdovska jama cave, as well as food residuals composed of wheat grains and plants in associated ceramics were isotopically analyzed. The results indicate that the human diet was based on foods of terrestrial origin consisting primarily of cereals and herbivores, most probably the domestic animals raised at that time. The significantly higher delta (super 15) N values found in infants and young children indicate "nursing effects". The pattern of dietary habits rapidly changed in older children accorded similar dietary status as their parents.

Stable carbon and nitrogen isotopes of boar bone collagen may help investigate this hypothesis, as agricultural products or leftovers of human diets can be distinguished from natural diets by their isotopic signature. Sus bones from archaeological sites (1700 to 7000 years BP) from the Japanese archipelago and the Ryukyu Islands were analyzed for carbon and nitrogen isotopes. Sus bones in Honshu, Kyushu, and Hokkaido islands fell into the same isotopic range (delta (super 13) C=-21.0+ or -1.3ppm and delta (super 15) N=4.2+ or -1.1ppm) and showed a similar range to deer (Cervus nippon) (delta (super 13) C=-21.5+ or -1.4ppm and delta (super 15) N=4.3+ or -1.0ppm) in the same regions, indicating that they were generally herbivores and eating mainly C (sub 3) plants in a natural ecosystem. However, Sus from Ryukyu Islands showed inconsistent and widely variable delta (super 15) N ratios, ranging from 4 to 12ppm with mean values of 9.2+ or -1.8ppm. No significant difference was found in delta (super 13) C (-20.2+ or -1.8ppm). Possible environmental and behavioral reasons for this discrepancy were investigated, but no direct evidence on the point was found in the Ryukyu Islands. We conclude that the evidence that suggests that Sus remains found in the Ryukyu Islands may have been imported alive into the islands from agricultural areas overseas after being raised by humans, and were then killed after free ranging on the islands for variable periods.

Throughout the growing season, CO (sub 2) concentration was maintained at 383+ or -11 mu mol mol (super -1) during the day and 446+ or -40 mu mol mol (super -1) at night for ambient CO (sub 2) treatment, and at 706+ or -13 mu mol mol (super -1) (day) and 780+ or -76 mu mol mol (super -1) (night) for the elevated CO (sub 2) treatment. At the grain-filling stage of growth, rice plants in the chambers were supplied with (super 13) C-enriched CO (sub 2) (delta (super 13) C = 413.9 ppm) for 3 days to study the allocation and transformation of photosynthetic carbon to root biomass, water-soluble organic carbon (WSOC) in soil solution, and CO (sub 2) and CH (sub 4) entrapped in the soil. Elevated atmospheric CO (sub 2) concentration not only directly increased the biomass above ground and in the roots by photosynthesis, but also indirectly increased the amounts of CH (sub 4) and CO (sub 2) entrapped in the soil. Most of the CO (sub 2) was dissolved in soil solution, but in contrast most of the CH (sub 4) existed in soil bubbles. When rice was fed with (super 13) C-enriched CO (sub 2) at the grain-filling stage of growth, the increase in (super 13) C of entrapped CO (sub 2) under ambient CO (sub 2) conditions accounted for 1.476% of the increase in (super 13) C of the rice plants and for 1.845% of the increase in (super 13) C of rice plants grown under elevated CO (sub 2) conditions. The increase in (super 13) C of entrapped CH (sub 4) accounted for 0.178% and 0.234% of the increase in (super 13) C of rice plants grown under ambient and elevated CO (sub 2) treatments, respectively. Under conditions of elevated CO (sub 2) the entrapped (super 13) C-CO (sub 21 and (super 13) C-CH (sub 4) increased by 57% and 65%, respectively. The increase in (super 13) C after feeding with (super 13) C-enriched CO (sub 2) , as a proportion of the total C of plants before feeding, was higher for CH (sub 4) entrapped in rice-paddy soil than for CO (sub 2) entrapped in rice-paddy soil, WSOC in soil solution, aboveground biomass, and root biomass under both ambient and elevated CO (sub 2) treatments. This indicates that during the grain-filling stage of rice growth, photosynthesized carbon had the most impact on CH (sub 4) production and accelerated the CH (sub 4) turnover rate.

In the wake of the discovery of large variations in (super 13) C/ (super 12) C ratios among various carbon-bearing materials including plants and fossil fuels, the contentious debate ensued between Kalervo Rankama and Harmon Craig in the early 1950s whether the origin of graphitic carbon in ancient rocks (biogenic vs. abiogenic) can be uniquely identified by its isotopic compositions. During the last half-century, great progress has been made in understanding biogeochemical processes in modern and ancient terrestrial environments. Rapid developments in the last decade of novel analytical techniques and the birth of new geoscience fields such as geomicrobiology and astrobiology has prompted resurgence in the application not only of conventional light stable isotopes, but also of those of metal and other intermediate elements. However, recent debates on the origin of graphitic carbons from Early Archean rocks from Australia and Greenland are very much reminiscent of the Rankama-Craig debate half a century ago. Here, an attempt is made to review briefly the history of isotope biosignatures and to critically assess current criteria for early life. A number of possible abiotic pathways exist that lead to the synthesis of various organic and reduced carbon compounds (alkanes, PAH, amino acids, lipids, graphitic carbon, etc.) depleted in (super 13) C due to large kinetic isotope effects (up to ca. -60PPM). It also seems very likely that the mantle contains indigenous carbons (graphite, diamond, dissolved carbons, carbide) with low delta (super 13) C values (-20ppm to -30ppm), which have previously been considered 1 recycled sedimentary organic carbons or surface contamination. This analysis prompts us to reassess our current and future strategies for identifying early and extraterrestrial life using isotope biosignatures.

The spatial distribution of delta (super 14) C and delta (super 13) C values of sedimentary organic matter was divided into those of (1) estuary, (2) continental shelf, and (3) continental slope. For shelf sediments, respective maxima can be seen for Delta (super 14) C value, C/N ratio and organic carbon content at a station near the river mouth. The mean grain size of surface sediments also exhibits a similar trend. The delta (super 13) C values show a minimum near the river mouth. The shelf composition does not appear to be a simple mixture of terrestrial and marine origin. From the above data, it is considered that the spatial distribution of Delta (super 14) C and delta (super 13) C values may reflect variations in dispersion and deposition processes together with the size fractionation of riverine suspended particles, the resuspension of sediments, and differences in the contribution of marine organic matter.

It is found that the SiO (sub 2) contents in ignited rice plant samples increased generally from roots, through SL (stem and leaves), to husks. Large and systematic silicon isotope fractionation was observed among different organs of individual rice plants. Their delta (super 30) Si values show a generally increasing trend from roots and SL, through husks, to grains, which can be explained by kinetic isotope fractionation in a Rayleigh process. A delta (super 30) Si value of 6.1ppm was obtained from two samples of rice grains, which is much greater than the highest value (3.4ppm) observed in terrestrial samples before. It is inferred that monosilicic acid is the major silicon-bearing component taken up by rice roots. Passive uptake of silicon is important for rice and evapotranspiration may be the major mechanism for the transportation and precipitation of silicon in rice plants. It is suggested that silicon isotope study has a potential application to agriculture and biogeochemistry.

Depositional ages for the 120 samples studied range from 3.3 to 2.2 Ga, and Fe, C, and S contents define several compositional groups, including samples rich in Fe, organic carbon, carbonate, and sulfide. The delta (super 56) Fe values for low-C (sub org) , low-C (sub carb) , and low-S sedimentary rocks are close to 0 ppm, the average of igneous rocks. This range is essentially the same as that of C (sub org) -poor late Cenozoic loess, aerosol, river loads, and marine sediments and those of C (sub org) -poor Phanerozoic-Proterozoic shales. That these delta (super 56) Fe values are the same as those of igneous rocks suggests that Fe has behaved conservatively in bulk sediments during sedimentary transport, diagenesis, and lithification since the Archean. These observations indicate that, if atmospheric O (sub 2) contents rose dramatically between 2.4 and 2.2 Ga, as proposed by many workers, such a rise did not produce a significant change in the bulk Fe budget of the terrestrial sedimentary system. If the Archean atmosphere was anoxic and Fe was lost from bedrock during soil formation, any isotopic fractionation between aqueous ferrous Fe (Fe (sub aq) (super 2+) ) and Fe-bearing minerals must have been negligible. In contrast, if the Archean atmosphere was oxic, Fe would have been retained as Fe (super 3+) hydroxides during weathering as it is today, which would produce minimal net isotopic fractionation in bulk detrital sediments. Siderite-rich samples have delta (super 56) Fe values of -0.5 approximately 0.5 ppm, and experimentally determined Fe (sub aq) (super 2+) -siderite fractionation factors suggest that these rocks formed from Fe (sub aq) (super 2+) that had similar or slightly higher delta (super 56) Fe values. The delta (super 56) Fe values calculated for Fe (sub aq) (super 2+) overlaps those of modern submarine hydrothermal fluids, but it is also possible that Fe (sub aq) (super 2+) had delta (super 56) Fe values higher than those of modern hydrothermal fluids, depending upon the Fe (sub aq) (super 2+) -Fe carbonate fractionation factor that is used. In contrast, C (sub org) -rich samples and magnetite-rich samples have strongly negative delta (super 56) Fe values, generally between -2.3 ppm and -1.0 ppm, and available fluid-mineral fractionation factors suggest that the Fe-bearing minerals siderite and magnetite in these rocks formed in the presence of Fe (sub aq) (super 2+) that had very low delta (super 56) Fe values, between -3 ppm and -1 ppm. Reduction of Fe (super 3+) hydroxide by sulfide, precipitation of sulfide minerals, or incongruent dissolution of silicate minerals are considered unlikely means to produce significant quantities of low-delta (super 56) Fe Fe (sub aq) (super 2+) . We interpret microbial dissimilatory Fe (super 3+) reduction (DIR) as the best explanation for producing such low delta (super 56) Fe values for Fe (sub aq) (super 2+) , and our results suggest that DIR was a significant form of respiration since at least 2.9 Ga.

The 28-norhopanoic acids exist mainly as free acids but are partly bound to kerogen and the polar fraction of the solvent extract via an ester bond. The (super 13) C depletions of C (sub 29) and C (sub 31) 28-norhopanoic acids compared with those of C (sub 30) and C (sub 32) regular hopanoic acids indicate that these 28-demethylated and regular hopanoic acids are derived from different precursor organisms. The Upper Onnagawa Formation contains abundant 28-norhopanoic acids and is characterized by the occurrence of Calyptogena sp. (Bivalvia), which lives in a specific chemoautrophic ecosystem that utilizes chemical substrates from hydrothermal vents or cold seeps. The depletion of 28-norhopanoic acids in (super 13) C compared with kerogen suggests that the 28-norhopanoic acids have been derived from bacteria that utilized (super 13) C-depleted CO (sub 2) as their carbon source.

Models have been developed showing advantages and disadvantages of sole proprietorships, partnerships, and corporations when applied as farm enterprises. In recent years, the farm cooperative business structure has taken on a different complexion, especially when faced with new crops and uses, mixed, multiple, and international markets, and cross-cutting market sectors. These new generation cooperatives have played a particularly strong role in developing renewable energy and agricultural enterprises, especially in the face of proposed new crop rotations, inclusion of perennial crops in these rotations, and different management scenarios based on agro-forestry principles. In this paper, we define conditions under which the farm cooperative is an appropriate business enterprise structure, and review and update the status of four of these new generation cooperative business structures in Minnesota, New York, and Iowa. We assess the status of development of these cooperatives and the market conditions needed for the agriculture, energy, and environmental sectors that comprise these cooperatives.

By using high-performance mass spectrometry to characterize the oxidized peptides created by the hydroxyl radical reactions, amino acid solvent-accessibility data for native and denatured C14S Sml1p that revealed a solvent-excluding tertiary structure in the native state were obtained. The data on solvent accessibilities of various amino acids within the protein were then utilized to evaluate the de novo computational models generated by the HMMSTR/Rosetta server. The top five models initially generated by the server all disagreed with both published nuclear magnetic resonance (NMR) data and the solvent-accessibility data obtained in this study. A structural model adjusted to fit the previously reported NMR data satisfied most of the solvent-accessibility constraints. Through minor adjustment of the rotamers of two amino acid side chains for this latter structure, a model that not only provided a lower energy conformation but also completely satisfied previously reported data from NMR and tryptophan fluorescence measurements, in addition to the solvent-accessibility data presented here, was generated.

Here we delineated the cellular response of MR-1 to UV radiation damage by analyzing the transcriptional profile during a 1-h recovering period after UVC, UVB, and UVA exposure at a dose that yields about a 20% survival rate. Although the SOS response was observed with all three treatments, the induction was more robust in response to short-wavelength UV radiation (UVB and UVC). Similarly, more prophage-related genes were induced by short-wavelength UV radiation. MR-1 showed an active detoxification mechanism in response to UVA, which included the induction of antioxidant enzymes and iron-sequestering proteins to scavenge reactive oxygen species. In addition, a great number of genes encoding multidrug and heavy metal efflux pumps were induced following UVA irradiation. Our data suggested that activation of prophages appears the major lethal factor in MR-1 following UVC or UVB irradiation, whereas oxidative damage contributes greatly to the high UVA sensitivity in MR-1.

Therefore, the development of field-usable detection devices for sensitive and selective detection of BW agents is an important issue. In this work, we report a portable biochip system based on complementary metal oxide semiconductor (CMOS) technology that has great potential as a device for single-bacteria detection. The possibility of single-bacteria detection is reported using an immunoassay coupled to laser- induced fluorescence (LIF) detection. Bacillus globigii spores, which are a surrogate species for B. anthracis spores, were used as the test sample. Enzymatic amplification following immunocomplex formation allowed remarkably sensitive detection of B. globigii spores, and could preclude a complicated optical and instrumental system usually required for high-sensitive detection. Atomic force microscopy (AFM) was employed to investigate whether B. globigii spores detected in the portable biochip system exist in single-cell or multicellular form. It was found that B. globigii spores mostly exist in multicellular form with a small minority of single-cell form. The results showed that the portable biochip system has great potential as a device for single- particle or possibly even single-organism detection.

The algorithm works by launching virtual entities that we call `walkers' from each patch of habitat in the map, simulating their travel as they journey through land cover types in the intervening matrix, and finally arrive at a different habitat `island.' Each walker is imbued with a set of user-specified habitat preferences that make its walking behavior resemble a particular animal species. Because the tool operates in parallel on a supercomputer, large numbers of walkers can be efficiently simulated. The importance of each habitat patch as a source or a sink for a species is calculated, consistent with existing concepts in the metapopulation literature. The manipulation of a series of contrived artificial landscapes demonstrates that the location of potential dispersal corridors and relative source and sink importance among patches can be purposefully altered in expected ways. Finally, potential dispersal corridors are predicted among remnant woodlots within three actual landscape maps.

We introduce DBDigger, an algorithm that reorganizes the database identification process to remove a problematic bottleneck. Typically such algorithms determine which candidate sequences can be compared to each spectrum. Instead, DBDigger determines which spectra can be compared to each candidate sequence, enabling the software to generate candidate sequences only once for each HPLC separation rather than for each spectrum. This reorganization also reduces the number of times a spectrum must be predicted for a particular candidate sequence and charge state. As a result, DBDigger can accelerate some database searches by more than an order of magnitude. In addition, the software offers features to reduce the performance degradation introduced by posttranslational modification (PTM) searching. DBDigger allows researchers to specify the sequence context in which each PTM is possible. In the case of CNBr digests, for example, modified methionine residues can be limited to occur only at the C-termini of peptides. Use of "context-dependent" PTM searching reduces the performance penalty relative to traditional PTM searching. We characterize the performance possible with DBDigger, showcasing MASPIC, a new statistical scorer. We describe the implementation of these innovations in the hope that other researchers will employ them for rapid and highly flexible proteomic database search.

The impact of textural and structural parameters on soil strength is moderated by soil organic C (SOC) concentration. Therefore, the objectives of this study were to assess differences in soil strength and SOC concentration in watersheds under long-term (>15 yr) management practices in the North Appalachian region on a predominantly Typic Hapludults on undulating slopes (>6% slope). Seven watersheds without field replication under moldboard plow (MP), chisel plow, disk with beef cattle manure (DiskM), no-till with beef cattle manure (NTm), no-till with no beef cattle manure (NTnm), pasture, and forest were studied. Cone index (CI), shear strength, bulk density (rho b), volumetric moisture content (theta (sub v) ), and SOC concentration were determined at the summit, backslope, and footslope landscape positions at the 0- to 10-, 10- to 20-, and 20- to 30-cm depths. The SOC concentration was slightly higher at the footslope than at the summit position in the cultivated watersheds. The rho b was lower at the footslope than at the summit in NTm (1.22 vs. 1.42 Mg m (super -3) ) and chisel (1.34 vs. 1.47 Mg m (super -3) ) treatments. Forest had the lowest CI (0.19 MPa), shear strength (6.11 kPa), and rho (sub b) (0.93 Mg m (super -3) ) and the highest SOC concentration (62.7 g kg (super -1) ), whereas MP had the highest CI (0.67 MPa), shear strength (25.5 kPa), rho (sub b) (1.44 Mg m (super -3) ), and the lowest SOC concentration (13.6 g kg (super -1) ) in the 0- to 10-cm depth (P0.42; P<0.01). Results show that landscape positions had small effect, but management, particularly manuring, had large and significant effects on soil strength and SOC concentration.

New data from the Upper Permian San Andres Formation of Texas (274-272 Ma) and Salado Formation of New Mexico (251 Ma), analyzed by the environmental scanning electron microscopy (ESEM) X-ray energy-dispersive spectrometry (EDS) method, along with published chemical compositions of fluid inclusions in Permian marine halites from North America (two formations of different ages) and the Central and Eastern European basins (eight formations of four different ages) show that Permian seawater shares chemical characteristics with modern seawater, including SO (sub 4) (super 2-) > Ca (super 2+) at the point of gypsum precipitation, evolution into Mg (super 2+) -Na (super +) -K (super +) -SO (sub 4) (super 2-) -Cl (super -) brines, and Mg (super 2+) /K (super 2+) ratios approximately 5. Permian seawater, however, is slightly depleted in SO (sub 4) (super 2-) and enriched in Ca (super 2+) , although modeling results do not rule out Ca (super 2+) concentrations close to those in present-day seawater. Na (super +) and Mg (super 2+) in Permian seawater are close to (slightly below) their concentrations in modern seawater. Permian and modern seawater are both classified as aragonite seas, with Mg (super 2+) /Ca (super +) ratios >2, conditions favorable for precipitation of aragonite and magnesian calcite as ooids and cements. The chemistry of Permian seawater was modeled using the chemical composition of brine inclusions for three periods: Lower Permian Asselian-Sakmarian (296-283 Ma), Lower Permian Artinskian-Kungurian (283-274 Ma), and Upper Permian Tatarian (258-251 Ma). Parallel changes in the chemistry of brine inclusions from equivalent age evaporites in North America, Central Europe, and Eastern Europe show that seawater underwent secular variations in chemistry over the 50 million years of the Permian. Modeled SO (sub 4) (super 2-) concentrations are 20 mmol per kg H (sub 2) O (mmolal) and 19 mmolal in the Asselian-Sakmarian and Artinskian-Kungurian, with higher concentrations in the Upper Permian Tatarian (23 mmolal). Modeled Ca (super 2+) is at or above its concentration in modern seawater throughout the Permian. Mg (super 2+) is close to (slightly below) its concentration in modern seawater (55 mmolal) in the Asselian-Sakmarian (52 mmolal), and Tatarian (52 mmolal), but slightly higher than modern seawater in the Artinskian-Kungurian (60 mmolal). Mg (super 2+) /Ca (super 2+) ratios are 3.5 (total range = 2.7 to 5.5) in the Lower Permian and rose slightly to 3.7 (total range = 3.1 to 5.8) in the Upper Permian, primarily due to decreases in Ca (super 2+) . These results are consistent with models that predict oscillations in the major-ion composition of Phanerozoic seawater on the basis of changes in the midocean ridge/river water flux ratio driven by changes in the rate of midocean ridge crust production.The Permian was characterized by low sea levels, icehouse conditions, and southern hemisphere glaciation. Such conditions, analogous to the present ice age, and the similarities between Permian seawater and modern seawater, all suggest that general Phanerozoic supercycles, driven by mantle convection and global volcanicity, also control the major-ion chemistry of seawater.

After deposition Hg can be subsequently re-emitted back to the atmosphere. One of the large uncertainties in quantifying Hg emissions from terrestrial surfaces is distinguishing between Hg originally present in the substrate and Hg deposited from the atmosphere and then re-emitted. This study characterized the potential for re-emission of Hg deposited in precipitation to desert soils. Non-polar deserts comprise roughly 36% of the earth's land surface so an understanding the process of air-soil exchange of Hg in these settings is important for development of global mass balance estimates. The study site was located 30 km from Reno, NV, on barren soil with low Hg concentration (0.01 mg Hg/kg). The natural abundance of Hg isotopes in air measured at the site agreed quite well with published values. A solution of 0.1 mg/L (super 198) Hg in the form of HgCl (sub 2) was added to a 4 m (super 2) area of soil in a simulated light rain event. During the night, 8.2+ or -3.6 mu g (super 198) Hg was applied to each m (super 2) of soil, and immediately after soil Hg fluxes were measured using three dynamic flux chambers, and isotope concentrations were determined using ICP-MS. After (super 198) Hg was applied to the soil, there was an immediate release of the isotope, and then emissions decreased exponentially. Within the first six hours after the isotope was added to the soil, approximately 12 ng/m (super 2) of (super 198) Hg was emitted to the atmosphere, followed by a relatively steady flux of the isotope at 0.2+ or -0.2 ng/m (super 2) /h for the remainder of the experiment (62 days). Over this time, approximately 180 ng/m (super 2) or 2.2% of the (super 198) Hg isotope was emitted from the soil. During the experiment, dry deposition of elemental Hg from the atmosphere was measured with an average deposition rate of 0.2+ or -0.1 ng/m (super 2) /h. Emission of Hg from the soil was observed after soil wetting with the isotope solution and after a storm event. The added moisture from the storm event did not affect (super 198) Hg flux. Results suggest that in this desert environment where there is limited precipitation, Hg deposited by wet processes is not readily re-emitted and that dry deposition of elemental Hg may be an important process.

Feebates are a market-based alternative in which vehicles with fuel consumption rates above a 'pivot point' are charged fees while vehicles below receive rebates. By choice of pivot points, feebate systems can be made revenue neutral. Feebates have been analyzed before. This study re-examines feebates using recent data, assesses how the undervaluing of fuel economy by consumers might affect their efficacy, tests sensitivity to the cost of fuel economy technology and price elasticities of vehicle demand, and adds assessments of gas-guzzler taxes or rebates alone. A feebate rate of $500 per 0.01 gallon per mile (GPM) produces a 16 percent increase in fuel economy, while a $1000 per 0.01GPM results in a 29 percent increase, even if consumers count only the first 3 years of fuel savings. Unit sales decline by about 0.5 percent but sales revenues increase because the added value of fuel economy technologies outweighs the decrease in sales. In all cases, the vast majority of fuel economy increase is due to adoption of fuel economy technologies rather than shifts in sales.

The coarse ecoregion divisions accurately capture intuitively-understood regional environmental differences, whereas the finer divisions highlight local condition gradients, ecotones, and clines. Such statistically generated ecoregions can be produced based on user-selected continuous variables, allowing customized regions to be delineated for any specific problem. By creating an objective ecoregion classification, the ecoregion concept is removed from the limitations of human subjectivity, making possible a new array of ecologically useful derivative products. A red-green-blue visualization based on principal components analysis of ecoregion centroids indicates with color the relative combination of environmental conditions found within each ecoregion. Multiple geographic areas can be classified into a single common set of quantitative ecoregions to provide a basis for comparison, or maps of a single area through time can be classified to portray climatic or environmental changes geographically in terms of current conditions. Quantified representativeness can characterize borders between ecoregions as gradual, sharp, or of changing character along their length. Similarity of any ecoregion to all other ecoregions can be quantified and displayed as a 'representativeness' map. The representativeness of an existing spatial array of sample locations or study sites can be mapped relative to a set of quantitative ecoregions, suggesting locations for additional samples or sites. In addition, the shape of Hutchinsonian niches in environment space can be defined if a multivariate range map of species occurrence is available.

The data series for coal and natural gas each reveal a consistent seasonal pattern, with a winter peak for gas and two peaks (summer and winter) for coal. The annual cycle of total emissions has an amplitude of about 20 Tg-C, and is dominated by CO sub(2) released from consumption of natural gas. Summation of the monthly estimates to obtain annual values reveals good agreement with other estimates of CO sub(2) emissions. The varying proportions of CO sub(2) emitted from each fuel type over the course of a year lead to an annual cycle in the carbon isotope ratio ( delta super(13)C), with a range of about 2 ppt. These monthly carbon emissions estimates should be helpful in understanding the carbon cycle by providing (1) monthly-seasonal input for carbon cycle models, (2) estimates of the annual cycle of the super(13)C isotope ratio in fossil-fuel CO sub(2) emissions and (3) data at fine enough time intervals to investigate effects of seasonal climate variations and changes in seasonally dependent use patterns of certain appliances (e.g. air conditioners) on fossil-fuel carbon emissions.

The potential is for an energy revolution as profound as the impact fiber optics has had on communications. The fiber optic 'information superhighway' was constructed by replacing copper wires with a higher capacity alternative. Superconductivity provides an 'energy superhighway' that greatly improves efficiency and capacity. The economic and energy impacts of superconductors are predicted to be huge. Many challenges are being addressed in order for superconductivity to play this important role in the electric power system. The difficult challenge is underway in many countries to manufacture electrical wire from the ceramic high-temperature superconducting (HTS) materials, while in parallel, super-efficient power devices that use these wires are being designed and demonstrated in field trials. The benefits can be substantial: HTS wires that are a resistance-free alternative to conventional wires while carrying 100 times the amount of electricity; oil-free electrical equipment that is environmentally benign, with half the energy losses and half the size of conventional alternatives; and addressable markets estimated to exceed US$10 billion per annum within the next two decades. The savings due to increased efficiency of HTS electric power products may exceed 36 million metric tons of CO sub(2) in Japan, and much higher numbers in the U.S. and Europe, if generation continues to rely upon fossil fuels.

AN - 67718101; 15819203 AB - Despite the key role microalgae play in introducing toxicants into aquatic food webs, little is known about the effects of environmental factors on metal accumulation by these primary producers. Environmental factors such as light and nutrients alter growth rates and may consequently influence metal concentrations in microalgae through growth dilution. Laboratory experiments suggested that metal uptake and elimination by microalgal biofilms were gradual enough to enable dilution of metals within the biofilms by photosynthetically accrued carbon, and a simple kinetic model of metal accumulation predicted significant variation in metal content due to growth dilution over the natural range of microalgal growth rates. The ratio of metal uptake to carbon uptake by microalgal biofilms decreased exponentially with increasing light in short-term laboratory experiments because photosynthesis was much more sensitive to a light gradient than was metal uptake. The effect of light on biofilm metal concentrations was confirmed in situ with a long-term experiment in which experimental shading of biofilms in a metal-contaminated stream decreased biofilm growth rates and caused a 3x increase in biofilm concentrations of twelve metals, including methylmercury. Slow growth at the primary producer level is a likely contributor to higher biotic metal concentrations in shaded, oligotrophic, or cold ecosystems.

Literature reports have concentrated on intensive investigation of static and agitated culture in liquid media containing high nutrient concentrations optimized for maximal cellulose production rates. The behavior of these bacteria on semisolid and solid surfaces has not been specifically addressed. The species Gluconacetobacter hansenii was examined for cellulose synthesis and colony morphology on a range of solid supports, including cotton linters, and on media thickened with agar, methyl cellulose, or gellan. The concentration and chemical structure of the thickening agent were found to be directly related to the formation of contiguous cellulose pellicules. Viability of the bacteria following freezer storage was improved when the bacteria were frozen in their cellulose pellicules.

AN - 67722291; 15819938 AB - Improved surface-based geophysical technologies that are commercially available provide a new level of detail that can be used to guide ground water remediation. Surface-based multielectrode resistivity methods and tomographic seismic refraction techniques were used to image to a depth of approximately 30 m below the surface at the Natural and Accelerated Bioremediation Research Field Research Center. The U.S. Department of Energy (DOE) established the research center on the DOE Oak Ridge Reservation in Oak Ridge, Tennessee, to conduct in situ field-scale studies on bioremediation of metals and radionuclides. Bioremediation studies are being conducted on the saprolite, shale bedrock, and ground water at the site that have been contaminated with nitrate, uranium, technetium, tetrachloroethylene, and other contaminants (U.S. DOE 1997). Geophysical methods were effective in imaging the high-ionic strength plume and in defining the transition zone between saprolite and bedrock zones that appears to have a significant influence on contaminant transport. The geophysical data were used to help select the location and depth of investigation for field research plots. Drilling, borehole geophysics, and ground water sampling were used to verify the surface geophysical studies.

While the limitations and potential pitfalls of conventional refraction methods are well-known the same is not true for refraction tomography. As refraction tomography becomes more widely used, the need to know and understand its capabilities as well as its limitations becomes more critical. In this study we created eight representative models for use in evaluating three commercially available codes as well as refraction tomography in general. These models range from simple two-layer or dipping-layer problems to more complicated models designed to represent features of karst terrains. We demonstrate quantitatively and qualitatively that all three codes perform at a similar level, although each has strengths and weaknesses. Refraction tomography performs well in many situations where conventional methods fail, e.g., where lateral or vertical gradients compose a significant component of the velocity structure.

Under transient flow conditions and with multiscale heterogeneities in the field, previous attempts to scale-up laboratory experiments have not answered definitely the questions about the governing mechanisms and the spatial extent of the influence of small-scale mass transfer processes such as matrix diffusion. The objective of this research is to investigate the effects of multiscale heterogeneity, mechanistic and site model conceptualization, and source term density effect on elucidating and interpreting tracer movement in the field. Tracer release and monitoring information previously obtained in a field campaign of multiple, conservative tracer injection under natural hydraulic gradients at a low-level waste disposal site in eastern Tennessee, United States, is used for the research. A suite of two-pore-domain, or fracture-matrix, groundwater flow and transport models are calibrated and used to conduct model parameter and prediction uncertainty analyses. These efforts are facilitated by a novel nested Latin-hypercube sampling technique. Our results verify, at field scale, a multiple-pore-domain, multiscale mechanistic conceptual model that was used previously to interpret only laboratory observations. The results also suggest that, integrated over the entire field site, mass flux rates attributable to small-scale mass transfer are comparable to that of field-scale solute transport. The uncertainty analyses show that fracture spacing is the most important model parameter and model prediction uncertainty is relatively higher at the interface between the preferred flow path and its parent bedrock. The comparisons of site conceptual models indicate that the effect of matrix diffusion may be confined to the immediate neighborhood of the preferential flow path. Finally, because the relatively large amount of tracer needed for field studies, it is likely that source term density effect may exaggerate or obscure the effect of matrix diffusion on the movement of tracers from the preferred flow path into the bedrock.

We measured daytime lacunal and sediment gas concentrations of Hg, which suggested that the lacunal space acts as temporary storage for Hg and CH sub(4). The absence of detectable Hg super(0) fluxes measured over uprooted (floating) plants and sediment incubation experiments suggest that the Hg super(0) emitted from emergent macrophytes such as Typha and Cladium originates in the sediment. Hg II in the rhizosphere is reduced to Hg super(0) in these sediments by various processes, and is then transported by the plants to the atmosphere by two separate processes. At night, Hg and CH sub(4) formed in the sediment accumulate in the lacunal space after crossing the root-sediment barrier. At sunrise, a form of pressurized through- flow purges the lacunal space of Typha into the atmosphere forming an early morning emission pulse for both gases, and coincidental peaks of CH sub(4) and Hg super(0) suggest that the same lacunal gas transport mechanism is involved. Later in the day while the release of methane continues to deplete the lacunal pool, the Hg super(0) flux increases again to form a second peak in the afternoon when the CH sub(4) emission has decreased. This peak parallels that of transpiration, and is presumably due to xylem transport of Hg super(0) from continued production of Hg super(0) in the rhizosphere, perhaps in response to release of root exudates. A mass balance for this [not, vert, similar]1500 ha wetland suggested that the total transpiration of Hg super(0) is [not, vert, similar]1 kg yr super(-1), or [not, vert, similar]20 times the amount evaded from the water surface.

AN - 67366032; 15650587 AB - The biokinetics of inhaled plutonium were analyzed using compartment models representing their behavior within the respiratory tract, the gastrointestinal tract, and in systemic tissues. The processes of aerosol deposition, particle transport, absorption, and formation of a fixed deposit in the respiratory tract were formulated in the framework of the Human Respiratory Tract Model described in ICRP Publication 66. The values of parameters governing absorption and formation of the fixed deposit were established by fitting the model to the observations in 530 autopsy cases. The influence of smoking on mechanical clearance of deposited plutonium activity was considered. The dependence of absorption on the aerosol transportability, as estimated by in vitro methods (dialysis), was demonstrated. The results of this study were compared to those obtained from an earlier model of plutonium behavior in the respiratory tract, which was based on the same set of autopsy data. That model did not address the early phases of respiratory clearance and hence underestimated the committed lung dose by about 25% for plutonium oxides. Little difference in lung dose was found for nitrate forms.

The database includes both subsoil and topsoil samples. An overall regression equation for predicting oven-dried bulk density from soil properties (R2 = 0.45, P 30%) of the variation in bulk density for Udox, Xererts, Ustands, Aquands, and Saprists. Relationships between bulk density with soil volume measured on oven-dried natural clods and bulk density with soil volume measured at field-moisture content and one-third bar were also determined (R2 = 0.70 and 0.69, respectively; P < 0.001). Utilizing the regression equations developed in this study, oven-dried bulk density predictions were obtained for 71% of the 85608 samples in the database without bulk density measurements. While improving on methods of previous analyses, this study illustrates that regression equations are a feasible alternative for bulk-density estimation.

Biomarkers diagnostic for anoxygenic photosynthesis by Chlorobiaceae are particularly abundant at the boundary and into the Early Triassic. Similar conditions prevailed in the contemporaneous seas off South China. Our evidence for widespread photic-zone euxinic conditions suggests that sulfide toxicity was a driver of the extinction and a factor in the protracted recovery.

AN - 51643107; 2006-008914 AB - Much literature exists regarding processes by which shales are transformed into slates. Included are mechanical, physical, and chemical processes. We consider here some aspects not treated by previous authors. Specifically, we consider the manner in which, during such processes, certain special crystal-chemical and physical properties of phyllosilicates might strongly enhance both their ability to form and recrystallize with a strongly preferred orientation, and the development of the P and Q domains. Regarding the crystal-chemical aspects, we call attention to adjustments in the cell dimensions of muscovite and chlorite in response to compositional changes commonly observed when shale is syntectonically transformed into slate. Typically, in slates, the muscovite is phengite-rich, and the chlorite, relatively Al-rich. Phengite-rich muscovite has elongate a and b cell dimensions, but a markedly shortened c dimension compared to pure muscovite. All three cell dimensions of Al-rich chlorite are shortened, especially in the c dimension. These changes in cell dimensions in phengite-rich muscovite and chlorite, combined with effects expected according to periodic bond-chain theory, may well energetically facilitate the observed flattening. With regard to physical aspects, we point out the potentially important role of the unusually large compressibility of some phyllosilicates, especially along the c cell dimension, and the control on it of the changes in mineral composition during slate formation. We suggest that to varying degrees, these special crystal-chemical and physical properties of phyllosilicates may contribute significantly to the relative ease of development of the typical structure of slates.

Additionally, desorption of U(VI) from spent resins was studied to separate U(VI) from resins with sorbed ClO sub(4) super(-) for waste segregation and minimization. Results indicate that all SBA resins investigated in this study strongly sorb U(VI). The gel-type polyacrylic resin (Purolite A850) showed the highest sorption affinity and capacity for U(VI) but was the least effective in sorbing ClO sub(4) super(-). The presence of SO sub(4) super(2-) had little impact on the sorption of U(VI) but significantly affected the sorption of ClO sub(4) super(-), particularly on monofunctional SBA resins. A dilute acid wash was found to be effective in desorbing U(VI) but ineffective in desorbing ClO sub(4) super(-) from bifunctional resins (Purolite A530E and WBR109). A single wash removed similar to 75% of sorbed U(VI) but only similar to 0.1% of sorbed ClO sub(4) super(-) from the bifunctional resins. On the other hand, only 21.4% of sorbed U(VI) but similar to 34% of sorbed ClO sub(4) super(-) was desorbed from the Purolite A850 resin. This study concludes that bifunctional resins could be used effectively to treat water contaminated with ClO sub(4) super(-) and traces of U(VI), and dilute acid washes could minimize hazardous wastes by separating sorbed U(VI) from ClO sub(4) super(-) prior to the regeneration of the spent resin loaded with ClO sub(4) super(-).

Using an individual-based model, we evaluate whether basic assumptions of species' life-history, drought-susceptibility, and shade tolerance generate dynamics that replicate patterns between and within forest stands. Location: Virginia piedmont, USA. Method: Model verification examines the transition in forest composition and stand structure between mesic, intermediate and xeric sites. At each site, tree location, diameter, and status were recorded in square plots ranging from 0.25 to 1.0 ha. Model validation examines the simulated spatial pattern of individual trees at scales of 1-25 m within each forest site using a univariate Ripley's K function. Results: 7512 live and dead trees were surveyed across all sites. All sites exhibit a consistent, significant shift in pattern for live trees by size, progressing from a clumped understorey (trees greater than or equal to 0.1 m in diameter) to a uniform overstorey (trees > 0.25 m). Simulation results reflect not only the general shift in pattern of trees at appropriate scales within sites, but also the general transition in species composition and stand structure between sites. Conclusions: This shift has been observed in other forest ecosystems and interpreted as a result of competition; however, this hypothesis has seldom been evaluated using simulation models. These results support the hypothesis that forest pattern in the Virginia piedmont results from competition involving species' life-history attributes driven by soil moisture availability between sites and light availability within sites.

The films responded well to a wide range of applied pressures (0.5-50 MPa), providing reliable estimates of pressures even when contained within waterproof plastic packaging, stacked under other films, and exposed at low water temperatures or low and high relative humidities. Waterproof packages of PSF were field-tested by wrapping them around polycarbonate plastic cylinders and passing them down the spillways of hydroelectric dams. Most of the spillway-passed PSF samples had marks indicating impacts. Many of the marks revealed high values of pressure (e.g., >40 MPa) that are likely to injure fish.

This need is most urgent in the area of homeland security, but also extends into medical, environmental, and agricultural sciences. Mass-spectrometry-based analysis is one of the leading technologies in the field with a diversity of different methodologies for biothreat detection. Over the past few years, "shotgun" proteomics has become one method of choice for the rapid analysis of complex protein mixtures by mass spectrometry. Recently, it was demonstrated that this methodology is capable of distinguishing a target species against a large database of background species from a single-component sample or dual-component mixtures with relatively the same concentration (Dworzanski, J. P.; Snyder, A. P.; Chen, R.; Zhang, H.; Wishart, D.; Li, L. Anal. Chem. 2004, 76, 2355-2366). Here, we examine the potential of shotgun proteomics to analyze a target species in a background of four contaminant species. We tested the capability of a common commercial mass-spectrometry-based shotgun proteomics platform for the detection of the target species (Escherichia coli) at four different concentrations and four different time points of analysis. We also tested the effect of database size on positive identification of the four microbes used in this study by testing a small (13-species) database and a large (261-species) database. The results clearly indicated that this technology could easily identify the target species at 20% in the background mixture at a 60, 120, 180, or 240 min analysis time with the small database. The results also indicated that the target species could easily be identified at 20% or 6% but could not be identified at 0.6% or 0.06% in either a 240 min analysis or a 30 h analysis with the small database. The effects of the large database were severe on the target species where detection above the background at any concentration used in this study was impossible, though the three other microbes used in this study were clearly identified above the background when analyzed with the large database. This study points to the potential application of this technology for biological threat agent detection but highlights many areas of needed research before the technology will be useful in real world samples.

The Charpy transition temperature-shift data is used as the primary index of the RPV radiation embrittlement in this study. Six parameters, Cu, Ni, P, neutron fluence, irradiation time, and irradiation temperature are used in the embrittlement prediction models. The results indicate that this new embrittlement predictor achieved about 66% and 53% reductions, respectively, in the uncertainties for the update General Electric (GE) Boiling Water Reactor (BWR) plate and weld data compared to the Nuclear Regulatory Commission (NRC) Regulatory Guide 1.99, Rev. 2 (RG1.99/R2).

Cultures of microorganisms were isolated at 8 degree C on nutrient agar medium prepared in artificial seawater. Isolates in this study could use a wide variety of electron acceptors such as oxygen, nitrate, and metals, and reduce various metals coupled to the oxidation of several organic acids, glucose or hydrogen at temperatures down to 0 degree C. Akaganeite was reduced to either magnetite or siderite, depending on the test conditions. The geochemical profiles at the sample sites from which these strains were isolated spanned a temperature range of 1.8 to 11 degree C, and all showed active oxygen and nitrate reduction as well as metal reduction. This confirms previous reports that sediment microorganisms participating in biogeochemical cycles remain active at low temperatures.

AN - 70152925; 16604703 AB - To support the Nuclear Criticality Safety Program, the Oak Ridge Electron Linear Accelerator (ORELA) has been used to measure the total and capture neutron cross sections of several nuclides in the energy range from 100 eV to -600 keV. Concerns about the use of existing cross section data in nuclear criticality calculations have been a prime motivator for the new cross-section measurements. Our new capture cross sections of aluminium, silicon, chlorine, fluorine and potassium in the energy range from 100 eV to 600 keV are substantially different from the cross sections in evaluated nuclear data files of ENDF/B-VI and JENDL-3.2.

AN - 70150896; 16604687 AB - The effective use of biasing for the Monte Carlo solution of a void streaming problem is essential to obtaining a reasonable result in a reasonable amount of time. Most general purpose Monte Carlo shielding codes allow for the user to select the particular biasing techniques best oriented to the particular problem of interest. The biasing strategy for void streaming problems many times differs from that of a deep penetration problem. The key in void streaming is to bias particles into the streaming path, whereas in deep penetration problems the biasing is aimed at forcing particles through the shield. Until recently, the biasing scheme in the SCALE SAS4 shielding module was considered inadequate for void streaming problems due to the assumed one-dimensional nature of the automated bias prescription. A modified approach to the automated biasing in SAS4 has allowed for significant gains to be realised in the use of the code for void streaming problems. This paper applies the modified SAS4 procedures to a spent fuel storage cask model with vent ports. The results of the SAS4 analysis are compared with those of the ADVANTG methodology, which is an accelerated version of MCNP. Various options available for the implementation of the SAS4 methodology are reviewed and recommendations offered.

AN - 70150463; 16604641 AB - The photo-nuclear physics model capabilities utilising the CEM2k model implemented in the MCNPX code were improved > 100 MeV photon energy by basing the photon transport on experimental photo-absorption cross sections of nuclides rather than on free nucleon cross sections. Below 100 MeV, the photo-nuclear physics model now uses isotope-specific giant dipole resonance (GDR) photo-absorption cross sections that are provided to the code in a parameterised form on a data file. Adjustments of the photo-fission cross sections were implemented to match the BOFOD evaluated data through a CEM2k internal parameter. The physics models with these improvements are better equipped to supplement the tabulated data based photo-nuclear MCNPX capability for isotopes with missing tabulated data evaluations especially in the GDR region, and has improved its predictive power at energies above the GDR resonances.

A variety of typical materials for accelerator shielding, such as concrete and steel, were used for construction of the door to study radiation penetration. A comparison was carried out using both Monte Carlo (code MCNPX) and discrete ordinates (code DORT) methods.

AN - 69046457; 16381717 AB - Because silicon is a major constituent of concrete and soil, neutron and gamma ray information on silicon is important for reactor shielding and criticality safety calculations. Therefore, much effort was put into the ENDF/B-VI evaluation for the three stable isotopes of silicon. The neutron capture cross section of natural silicon was recently measured at the Oak Ridge Electron Linear Accelerator (ORELA) in the energy range 1-700 keV. Using the ENDF/B-VI evaluation for initial values, a new evaluation of the resonance parameters was performed by adding the results of the ORELA capture measurements to the experimental database. The computer code SAMMY was used for the analysis of the experimental data; the new version of SAMMY allows accurate calculations of the self-shielding and multiple scattering effects in the capture measurements. The accuracy of the radiative capture widths of the resonances was improved by this analysis. Accurate values of the s-, p- and d-wave neutron strength functions were also obtained. Although the resonance capture component of the present evaluation is 2-3 times smaller than that in ENDF/B-VI, the total capture cross section is much larger, at least for energies >250 keV, because the direct capture component contributes values of the same order of magnitude as the resonance component. The direct component was not taken into account in the ENDF/B-VI evaluation and was calculated for the first time in the present evaluation.

Existing neutron beam shutters can be replaced with concrete at low power or with concrete and steel at approximately 500 kW of beam power. Potential voids in the hot cell walls are analysed to determine the impact on dose rates as a function of void size.

AN - 69045124; 16381699 AB - Covariance data are required to assess uncertainties in design parameters in several nuclear applications. The error estimation of calculated quantities relies on the nuclear data uncertainty information available in the basic nuclear data libraries, such as the US Evaluated Nuclear Data Library, ENDF/B. The uncertainty files in the ENDF/B library are obtained from the analysis of experimental data and are stored as variance and covariance data. In this paper we address the generation of covariance data in the resonance region done with the computer code SAMMY. SAMMY is used in the evaluation of the experimental data in the resolved and unresolved resonance energy regions. The data fitting of cross sections is based on the generalised least-squares formalism (Bayesian theory) together with the resonance formalism described by R-matrix theory. Two approaches are used in SAMMY for the generation of resonance parameter covariance data. In the evaluation process SAMMY generates a set of resonance parameters that fit the data, and, it provides the resonance parameter covariances. For resonance parameter evaluations where there are no resonance parameter covariance data available, the alternative is to use an approach called the 'retroactive' resonance parameter covariance generation.

AN - 68800731; 16291182 AB - An operational framework is developed to serve as a guideline for investigating causal relationships between environmental stressors and effects on marine biota. Because of the complexity and variability of many marine systems, multiple lines of evidence are needed to understand relationships between stressors and effects on marine resources. Within this framework, a weight of evidence approach based on multiple lines of evidence are developed and applied in a sequential manner by (1) characterizing the study system which involves determining if target biota are impaired, assessment of food and habitat availability, and measuring contaminant levels in the environment, (2) assessing direct effects of contaminant exposure on target biota using biomarkers and assessing indirect effects of exposure using suites of bioindicators, and (3) applying standard causal criteria based on epidemiological principles and diagnostic health profiling techniques to assess potential causes. Use of multiple lines of evidence should also reduce the risk of false positives (Type I error or falsely concluding that there is a causal relationship when there is none) and false negatives (Type II error or falsely concluding there is not a causal relationship when there actually is). Understanding causal relationships and the mechanistic processes between environmental stressors and effects on biota is important in the effective management and restoration of impaired marine ecosystems.

Experimental results show that Nd (super 3) sorbs strongly, even at low temperature, with adsorption commencing below the pH (sub znpc) of rutile. In addition, there is a systematic increase in Nd (super 3) adsorption with increasing temperature. The experimental results were rationalized and described using surface oxygen proton affinities computed from the MUlti SIte Complexation or MUSIC model, coupled with a Stern-based three-layer description of the oxide/water interface. Moreover, molecular-scale information was incorporated successfully into the surface complexation model, providing a unique geometry for the adsorption of Nd (super 3) on rutile. The primary mode of Nd (super 3) adsorption was assumed to be the tetradentate configuration found for Y (super 3) adsorption on the rutile (110) surface from previously described in situ X-ray standing wave experiments, wherein the sorbing cations bond directly with two adjacent "terminal" and two adjacent "bridging" surface oxygen atoms. Similarly, the adsorption of Na counterions was also assumed to be tetradentate, as supported by MD simulations of Na interactions with the rutile (110) surface, and by analogous X-ray standing wave results for Rb adsorption on rutile. Fitting parameters for Nd (super 3) adsorption included binding constants for the tetradentate adsorption complex and capacitance values for the inner-sphere binding plane. In addition, hydrolysis of the tetradentate adsorption complex was permitted and resulted in significantly improved model fits at higher temperature and pH values. The modeling results indicate that the Stern-based MUSIC surface-complexation model adequately accommodates molecular-scale information to uniquely rationalize and describe multivalent ion adsorption systematically into the hydrothermal regime.

The results show overall higher isotopic values for summer versus winter precipitation, but steeper, positive slopes for the winter-precipitation curves. Where soil temperature is equated to mean annual temperature, the summer-precipitation curves are nearly flat at high latitudes and have a negative slope at low latitudes. In all cases, the delta (super 18) O values increase with increasing percent evaporation of soil water. Oxygen isotopic data for Early (Aptian) and Late (Maastrichtian) Cretaceous palaeosol calcite as a function of palaeolatitude of the Western Interior of North America plot in the modern winter-precipitation field, which, along with vertic features, may suggest a winter-wet palaeoclimate. Steeper, positive slopes for the Cretaceous curves compared to the modern curves may be attributable to greater latitudinal gradients in mean annual temperature and soil temperature in the Cretaceous compared to today, and/or to a greater degree of evaporation in Cretaceous soils at low latitudes compared to the modern earth. Distinguishing between these possibilities will require a more complete understanding of the variables that affect oxygen isotopes in pedogenic calcite, as well as better Cretaceous terrestrial palaeoclimate proxies with which to compare the isotopic data.

The application of this approach was successful in a case study on a predominantly agricultural area (Namwon, Korea). For this study, a total of 279 groundwater samples were collected from 93 wells distributed over the study area and analyzed for pH, alkalinity, major cations (Ca (super 2+) , Mg (super 2+) , Na (super +) , K (super +) ), major anions (NO (sub 3) (super -) , Cl (super -) , SO (sub 4) (super 2-) ), and silica. Nitrate, chloride, and sulfate concentrations point to the influence of anthropogenic activities on the groundwater composition. Increasing concentrations of major anions and cations toward the top of the aquifer suggests that they come mostly from surface sources. Mass balance analysis based on reaction stoichiometry reveals that the water chemistry is regulated primarily by the combination of three processes: (1) the weathering of minerals such as silicates, carbonates, and/or lime; (2) the input of Cl/SO (sub 4) salts; and (3) the generation of nitrates (through nitrification and/or aerobic decomposition of organic matter). Based on this mass balance analysis, we could also quantify the contributions of each process to the observed water chemistry. The results show that mineral weathering is the predominant process affecting groundwater chemistry. Groundwaters more influenced by anthropogenic activities generally show the larger effect of mineral weathering, suggesting that (1) the weathering of silicates might be triggered by protons generated from nitrate generation and/or (2) the water chemistry is affected by lime (CaO) applied to cultivated land and/or carbonates (i.e., CaCO (sub 3) ) in cement materials. However, the influence of protons, which can be co-produced with nitrate, on concentrations of major cations and alkalinity due to ion exchange were revealed to be negligible because the studied groundwater has sufficient alkalinity to neutralize those acids.

Despite the fact that the effect of dissolved salts on isotope partitioning in aqueous systems (the isotope salt effect) was discovered in the early 1950s, soon after carbonate paleothermometry commenced, it took isotope geochemists decades to understand the detail and geochemical significance of the effects, particularly those at elevated temperatures. The effect of pressure, which is potentially large under subduction zone and mantle conditions, has been even more elusive. The 1990s witnessed several significant breakthroughs in experimental and theoretical developments for understanding the effect of these variables on equilibrium isotope partitioning. The controversy of high temperature (>100 degrees C) isotope salt effects was finally resolved. It was demonstrated later that significant pressure effects exist for D/H fractionation between a hydrous mineral and water at 200-600 degrees C and at pressures to 0.8 GPa. Theoretical advances in understanding the isotope pressure effects, on both minerals and water, were also made during this period. Finally, and unexpectedly, the effects of dissolved minerals were proved to be significant on isotopic distributions in aqueous systems at high temperature and pressure (750 degrees C and 1.5 GPa). This article reviews historical development of these "other" effects in isotope thermometry, highlighting significant discoveries of the past decade.

These droplets need to be separated before the air is released to the environment. The use of an electric field to separate water droplets from an air stream has been investigated. A test chamber of 10 x 10cm cross-section and approximately 94 cm long mounted vertically was set up without packing, with two parallel-plate steel electrodes facing each other at a distance of 8 cm. An air stream containing water droplets formed by ultrasonic humidifiers was forced through the chamber. A laser-light-scattering particle-sizing system was used to measure the droplet size distribution. The droplet removal efficiency increased approximately linearly with electric field strength over the range investigated except when the field was raised to 3.0 to 3.50kV/cm, suggesting a saturation effect. The analysis showed that the removal efficiency is a function of the initial droplet concentration. For instance, for a droplet concentration of 24.2 g/m3, the maximum removal efficiency was approximately 85%, while that for a concentration of 8.3 g/m3 was 65% under the same experimental conditions. Droplet size measurements revealed that the average size of droplets did not change significantly with voltage; however, the number distribution of drops did change. Appreciable changes in the number of droplets were observed for droplet sizes in a typical range of 4 to 10 mm. The results of this research may be useful in developing effective applications of electric fields for the elimination of mist from air or gaseous streams.

Their generation of methane by anaerobic bacteria suggests that landfills may act as bioreactors for methylated mercury compounds. Since our previous study at a single Florida landfill, gaseous inorganic and methylated mercury species have now been identified and quantified in landfill gas at nine additional municipal landfills in several regions of the US. Total gaseous mercury occurs at concentrations in the mu g m super(-3) range, while methylated compounds occur at concentrations in the ng m super(-3) range at all but one of the landfill sites. Dimethylmercury is the predominant methylated species, at concentrations up to 100 ng m super(-3), while monomethyl mercury was generally lower. Limited measurements near sites where waste is exposed for processing (e.g. working face, transfer areas) suggest that dimethylmercury is released during these activities as well. Although increasing amounts of landfill gas generated in the US are flared (which should thermally decompose the organic mercury to inorganic mercury), unflared landfill gas is a potentially important anthropogenic source of methylated mercury emissions to the atmosphere.

Most existing databases, with few exceptions are not designed to easily support large scale computational analysis, but rather offer exclusively a web interface to the resource. We have recognized the growing need for a database which can be used successfully as a backend to computational analysis tools and pipelines. Such database should be sufficiently versatile to allow easy system integration. Results: GeneKeyDB is a gene-centered relational database developed to enhance data mining in biological data sets. The system provides an underlying data layer for computational analysis tools and visualization tools. GeneKeyDB relies primarily on existing database identifiers derived from community databases (NCBI, GO, Ensembl, et al.) as well as the known relationships among those identifiers. It is a lightweight, portable, and extensible platform for integration with computational tools and analysis environments. Conclusions: GeneKeyDB can enable analysis tools and users to manipulate the intersections, unions, and differences among different data sets.

In solid tumors, the processes of angiogenesis and metastasis potentially give rise to unique epitopes not usually accessible in homeostatic organs. Specific targeting of solid tumors for radioimmunotherapy requires that the targeting agent accumulate rapidly and at high levels at the tumor site. This study involved the selection of scFvs that recognize laminin-1 in vitro from the Tomlinson I and J phage display libraries. Selected, purified scFvs were radioiodinated and injected in tumor-bearing mice. One of these, scFv 15-9, exhibited preferential accumulation at subcutaneous tumors when compared to other antilaminin scFvs or to a control scFv. Autoradio graphic analysis indicated that scFv15-9 also displayed a higher vessel:parenchyma ratio than did two other antilaminin scFvs, scFv 15-6 and scFv 15-1, indicating a preferential accumulation of scFv 15-9 around vessel structures. Immunohisto-chemistry confirmed that scFv 15-9 accumulated at sites of endothelial cells lining vessel structures where significant levels of laminin were present. These data demonstrate that scFv 15-9 binds to a specific epitope on laminin and has potential for tumor endoradiotherapy in subcutaneous tumors.

In this article, we describe two stochastic models for simulating the spatial distribution of brine spills on a landscape. One model uses general assumptions about the spatial arrangement of spills and their sizes; the second model distributes spills by siting rectangular well complexes and conditioning spill probabilities on the configuration of pipes. We present maps of landscapes with spills produced by the two methods and compare the ability of the models to reproduce a specified spill area. A strength of the models presented here is their ability to extrapolate from the existing landscape to simulate landscapes with a higher (or lower) density of oil wells.

The presence of random and seasonal components in hydrological time series, like rainfall or runoff, makes the detection process challenging. Tests with simulated data demonstrate the presence of thresholds, in terms of noise to chaotic-signal and seasonality to chaotic-signal ratios, beyond which the set of currently available tools is not able to detect the chaotic component. The investigations also indicate that the decomposition of a simulated time series into the corresponding random, seasonal and chaotic components is possible from finite data. Real stream-flow data from the Arkansas and Colorado rivers are used to validate these results. Neither of the raw time series exhibits chaos. While a chaotic component can be extracted from the Arkansas data, such a component is either not present or can not be extracted from the Colorado data. This indicates that real hydrologic data may or may not have a detectable chaotic component. The strengths and limitations of the existing set of tools for the detection and modeling of chaos are also studied.

The present study of etoposide effects involved two end points of meiotic events known to occur in primary spermatocytes-chromosomal crossing-over and segregation. By following assortment of 13 microsatellite markers in two chromosomes (Ch 7 and Ch 15) it was shown that etoposide significantly affected crossing-over, but did not do so in a uniform fashion. Treatment generally changed the pattern for each chromosome, leading to local decreases in recombination, a distal shift in locations of crossing-over, and an overall decrease in double crossovers; at least some of these results might be interpreted as evidence for increased interference. Two methods were used to explore etoposide effects on chromosome segregation: a genetic experiment capable of detecting sex-chromosome nondisjunction in living progeny; and the use of FISH (fluorescence in situ hybridization) technology to score numbers of Chromosomes X, Y, and 8 in spermatozoa. Taken together these two approaches indicated that etoposide exposure of pachytene spermatocytes induces malsegregation, and that the findings of the genetic experiment probably yielded a marked underestimate of nondisjunction. As indicated by certain segregants, at least part of the etoposide effect could be due to disrupted pairing of achiasmatic homologs, followed by precocious sister-centromere separation. It has been shown for several organisms that absent or reduced levels of recombination, as well as suboptimally positioned recombination events, may be associated with abnormal segregation. Etoposide is the only chemical tested to date for which living progeny indicates an effect on both male meiotic crossing-over and chromosome segregation. Whether, however, etoposide-induced changes in recombination patterns are direct causes of the observed malsegregation requires additional investigation.

AN - 67217860; 15669338 AB - The detection and identification of microorganisms in natural communities is a great challenge to biologists. Microarray-based genomic technology provides a promising high-throughput alternative to traditional microbial characterization. A novel prototype microarray containing whole genomic DNA, termed community genome array (CGA), was constructed and evaluated. Microarray hybridizations at 55 degrees C using 50% formamide permitted the examined bacteria to be distinguished at the species level, while strain-level differentiation was obtained at hybridization temperatures of 65 or 75 degrees C. The detection limit was estimated to be approximately 0.2 ng with genomic DNA from a single pure culture using a reduced hybridization volume (3 microL). Using mixtures of known amounts of DNA or a known number of cells from 14 or 16 different species, respectively, about 5 ng of genomic DNA or 2.5 x 10(5) cells were detected under the hybridization conditions used. In addition, strong linear relationships were observed between hybridization signal intensity and target DNA concentrations for pure cultures, a mixture of DNA templates, and a population of mixed cells (r2 = 0.95-0.98, P < 0.01). Finally, the prototype CGA revealed differences in microbial community composition in soil, river, and marine sediments. The results suggest that CGA hybridization has potential as a specific, sensitive, and quantitative tool for detection and identification of microorganisms in environmental samples.

AN - 67144595; 15576789 AB - The availability of the complete genome sequence for Shewanella oneidensis MR-1 has permitted a comprehensive characterization of the ferric uptake regulator (Fur) modulon in this dissimilatory metal-reducing bacterium. We have employed targeted gene mutagenesis, DNA microarrays, proteomic analysis using liquid chromatography-mass spectrometry, and computational motif discovery tools to define the S. oneidensis Fur regulon. Using this integrated approach, we identified nine probable operons (containing 24 genes) and 15 individual open reading frames (ORFs), either with unknown functions or encoding products annotated as transport or binding proteins, that are predicted to be direct targets of Fur-mediated repression. This study suggested, for the first time, possible roles for four operons and eight ORFs with unknown functions in iron metabolism or iron transport-related functions. Proteomic analysis clearly identified a number of transporters, binding proteins, and receptors related to iron uptake that were up-regulated in response to a fur deletion and verified the expression of nine genes originally annotated as pseudogenes. Comparison of the transcriptome and proteome data revealed strong correlation for genes shown to be undergoing large changes at the transcript level. A number of genes encoding components of the electron transport system were also differentially expressed in a fur deletion mutant. The gene omcA (SO1779), which encodes a decaheme cytochrome c, exhibited significant decreases in both mRNA and protein abundance in the fur mutant and possessed a strong candidate Fur-binding site in its upstream region, thus suggesting that omcA may be a direct target of Fur activation.

2005-023356 AB - Nanoscale isotope and chemical images of grains of Amelia albite that were reacted with 2 m (super 18) O-enriched solution of KCl show a correspondence between O-isotope exchange and K-Na exchange. Experiments were conducted for 4-6 d at 600 degrees C and 200 MPa. After 6 d, the 150 mu m diameter albite grains had 5-20 mu m rims in which Na was nearly completely replaced by K and in which the O was strongly enriched in (super 18) O. The boundary between the core albite and the K-feldspar replacement is sharp and decorated with numerous pores. The distribution of Na and K, determined by electron probe microanalysis, is uniform within the core and rim and has an abrupt discontinuity at the interface. No evidence exists for K-Na interdiffusion at the resolution of electron probe. The NanoSIMS shows that the interface is also sharp in the distribution of (super 18) O and (super 16) O. The NanoSIMS image data and the electron probe data were coregistered; principal components analysis of the merged data set shows that 86% of the total variance in the data result from a single principal component loaded by the replacement of Na by K and (super 18) O. The combined electron probe and NanoSIMS analyses indicate that both cation and isotope exchange occurred during solution and reprecipitation of the feldspar.

Soils are the primary terrestrial repository for carbon, so minor changes in the balance between belowground carbon storage and release could have major impacts on greenhouse gases. Soil fauna, roots, fungi, and microbes interact with mineral and organic matter to process soil carbon. Studies have been hampered by the difficulty of observing processes beneath the earth's surface, but advances in science and technology are improving our ability to understand belowground ecosystems.

Artillery, wheeled, and tracked vehicle training at military installations can produce soil disturbance and potentially create barren, degraded soils. Ecosystem reclamation is an important component of natural resource management at military installations. Four factors were important to the development of thresholds to recovery of aboveground biomass on degraded soils: (1) initial amounts of aboveground biomass, (2) initial soil C stocks (i.e., soil quality), (3) relative recovery rates of biomass, and (4) soil sand content. Forests and old fields on soils with varying sand content had different predicted thresholds for ecosystem recovery. Soil C stocks at barren sites on Fort Benning were generally below predicted thresholds to 100% recovery of desired future ecosystem conditions defined on the basis of aboveground biomass. Predicted thresholds to ecosystem recovery were less on soils with more than 70% sand content. The lower thresholds for old field and forest recovery on more sandy soils were apparently due to higher relative rates of net soil N mineralization. Calculations with the model indicated that a combination of desired future conditions, initial levels of soil quality (defined by soil C stocks), and the rate of biomass accumulation determine the predicted success of ecosystem recovery on disturbed soils.

In this investigation, a large number of laboratory and field studies that measured the bioaccumulation of inorganic chemicals in plants were reviewed. The objective was to discern whether or not the relationship between the concentration of the element in aboveground vegetation and that in soil was different if the contamination was aged in the field rather than freshly added to soil in salt solution. For two of the eight elements, selenium and cadmium, salt solution experiments were associated with greater soil-plant uptake ratios than field measurements. Thus, these are not reliable data for use in the derivation of plant uptake regressions for screening-level ecological risk assessments at field sites. In contrast, the plant uptake of arsenic, copper, lead, mercury, nickel, and zinc, when added in salt solutions, was generally within the 95%prediction limit of regressions derived from field data. Chemical form, plant taxon, soil type, experimental methodology, and aging may be as important as the source of the chemical in predicting plant uptake of inorganic chemicals from soil.

This system consists of three essential components, Protein Function Groups (PFGs), PFG profiles and rules. The PFGs, established from an integrated analysis of current knowledge of protein functions from Swiss-Prot database and protein family-based sequence classifications, cover all possible cellular functions available in the database. The PFG profiles illustrate detailed protein features in the PFGs as in sequence conservations, the occurrences of sequence-based motifs, domains and species distributions. The rules, extracted from the PFG profiles, describe the clear relationships between these PFGs and all possible features. As a result, the RuleMiner is able to provide an enhanced capability for protein function analysis, such as results from the integrated sequence analysis tools for given proteins can be comparatively analyzed due to the clear feature-PFG relationships. Also, much needed guidance is readily available for such analysis. If the rules describe one-to-one (unique) relationships between the protein features and the PFGs, then these features can be utilized as unique functional identifiers and cellular functions of unknown proteins can be reliably determined. Otherwise, additional information has to be provided.

Spatial uncertainty in these data can propagate into model predictions. Uncertainty analysis, sensitivity analysis, error analysis, error budget analysis, spatial decision analysis, and hypothesis testing using neutral models are all techniques designed to explore the relationship between variation in model inputs and variation in model predictions. Although similar methods can be used to answer them, these approaches address different questions. These approaches differ in (a) whether the focus is forward or backward (forward to evaluate the magnitude of variation in model predictions propagated or backward to rank input parameters by their influence); (b) whether the question involves model robustness to large variations in spatial pattern or to small deviations from a reference map; and (c) whether processes that generate input uncertainty (for example, cartographic error) are of interest. In this commentary, we propose a taxonomy of approaches, all of which clarify the relationship between spatial uncertainty and the predictions of ecological models. We describe existing techniques and indicate a few areas where research is needed.

However, the genetic basis and regulatory mechanisms underlying the ability of S. oneidensis to survive and adapt to various environmentally relevant stresses is poorly understood. To define this organism's molecular response to elevated growth temperatures, temporal gene expression profiles were examined in cells subjected to heat stress by using whole-genome DNA microarrays for S. oneidensis. Approximately 15% (n = 711) of the total predicted S. oneidensis genes (n = 4,648) represented on the microarray were significantly up- or downregulated (P < 0.05) over a 25-min period after shift to the heat shock temperature. As expected, the majority of the genes that showed homology to known chaperones and heat shock proteins in other organisms were highly induced. In addition, a number of predicted genes, including those encoding enzymes in glycolysis and the pentose cycle, serine proteases, transcriptional regulators (MerR, LysR, and TetR families), histidine kinases, and hypothetical proteins were induced. Genes encoding membrane proteins were differentially expressed, suggesting that cells possibly alter their membrane composition or structure in response to variations in growth temperature. A substantial number of the genes encoding ribosomal proteins displayed downregulated coexpression patterns in response to heat stress, as did genes encoding prophage and flagellar proteins. Finally, a putative regulatory site with high conservation to the Escherichia coli capital sigma super(32)-binding consensus sequence was identified upstream of a number of heat-inducible genes.

Chu, H. Ohmoto, Kinetics of isotope exchange reactions involving intra- and intermolecular reactions: I. Rate law for a system with two chemical compounds and three exchangeable atoms. Geochim. Cosmochim. Acta 55 1991 1953-1961]. According to the rate law, the isotope exchange reaction is comprised of one overall intramolecular exchange between sulfane (-SH or SH) and sulfonate (-SO (sub 3) H or SO (sub 3) H) sulfurs of thiosulfate (i.e., SHSO (sub 3) H in thiosulfate) and two overall intermolecular exchanges between sulfide and sulfane sulfur of thiosulfate (i.e., H (sub 2) SSH of thiosulfate) and between sulfide and sulfonate sulfur of thiosulfate (i.e., H (sub 2) SSO (sub 3) H of thiosulfate). The rate constants for the three overall exchange reactions and the equilibrium isotopic fractionation factors among sulfide, sulfane, and sulfonate of thiosulfate were estimated by fitting [F. Uyama, H. Chiba, M. Kusakabe, H. Sakai, Sulfur isotope exchange reaction in the aqueous system: thiosulfate-sulfide-sulfate at hydrothermal temperature. Geochem. J. 19 1985 301-315] experimental data on sulfur isotope exchange between aqueous H (sub 2) S and sodium thiosulfate by the least squares method. At temperatures of 100-170 degrees C, the equilibrium fractionation factors (in per mil) can be expressed as: 1000lnalpha (sub H2S-SH) = -0.327 + or - 0.055(10 (super 2) /T (super 4) ) + 2.676 + or - 0.341(10 (super 6) /T (super 2) ; 1000lnalpha (sub SO3H-SH) = 0.352 + or - 0.009(10 (super 12) /T (super 4) ) + 7.523 + or - 0.054(10 (super 6) /T (super 2) ) and 1000lnalpha (sub SO3H-H2S) = 0.0293 + or - 0.058(10 (super 12) /T (super 4) ) - 4.871 + or - 0.357(10 (super 6) /T (super 2) ) (T in K). At near-neutral pH, the overall rate (m (super -1) s (super -1) ) for the sulfur isotope exchange between H (sub 2) S and -SO (sub 3) H of thiosulfate is described by logk (sub SOH (sub 2) S = 5.14(10 (super 3) /T) + 10.35 (T in K) with an activation energy of 98.3 kJ/mol at 100-170 degrees C. A comparison of the rates of sulfur exchanges among H (sub 2) S, -SH, and -SO (sub 3) H of thiosulfate with the rates of polysulfide-thiosulfate formation and disproportion reactions determined by [W. F. Giggenbach, Kinetics of the polysulfide-thiosulfate disproportionation up to 240 degrees C. Inorg. Chem. 13 1974b 1730-1733] suggests that the sulfur isotope exchanges between aqueous sulfide and thiosulfate may proceed via the formation and disproportionation of polysulfides (e.g., S (sub 3) S (super 2-) , S (sub 4) S (super 2-) , etc.): 10H (sub 2) S+3S (sub 2) O (sub 3) (super 2-) = 4S (sub 3) S (super 2-) +2H (super +) +9H (sub 2) O and S (sub n) S (super 2-) +SSO (sub 3) (super 2-) = S (sub n+1) S (super 2-) +SO (sub 3) (super 2-) . The disproportionation reaction of polysulfides appears to control the exchange rate between S (super 2-) and S (super 6+) atoms in thiosulfate and is considered the rate-determining step in the sulfate-sulfide exchange reaction rather than the intramolecular exchange of thiosulfate proposed by [H. Ohmoto, A. C. Lasaga, Kinetics of reactions between aqueous sulfates and sulfides in hydrothermal systems. Geochim. Cosmochim. Acta 46 1982 1727-1745]. Therefore, polysulfides may play an important role in the chemical and isotopic reactions between aqueous sulfide and sulfate under hydrothermal conditions.

The phase diagram shows a one-phase vapor field, a one-phase brine field, two-phase vapor + halite, vapor + brine, and brine + halite fields, and a three-phase vapor + brine + halite field. The halite-saturated vapor ranges in composition from x (sub NaCl) approximately 0 in CO (sub 2) to 0.08 at the vapor corner of the three-phase field, where x (sub H2O) approximately 0.6. The a (sub H2O) was fixed during the experiment, and the a (sub NaCl) in the vapor was fixed by saturation with halite. The a (sub CO2) was determined by integrating the Gibbs-Duhem equation along the saturation curve, Sigma ITx (sub i) d lna (sub i) = 0. The effect of adding NaCl to H (sub 2) O-CO (sub 2) vapor is represented by values of delta ln(gamma (sub H2O) )/delta x (sub NaCl) ranging from -7 in CO (sub 2) -rich vapor to 3 in H (sub 2) O-rich vapor. The value of delta ln(gamma (sub CO2) )/delta x (sub NaCl) shows an even larger range from 10 to -18 over the same compositional range. The measured values of the activities in the three-component system are combined with models for the activities in the H (sub 2) O-CO (sub 2) and H (sub 2) O-NaCl binaries to calculate the complete phase diagram.

Together they form the final two steps of a new, energy-efficient chemical process (patent pending) for converting serpentine to magnesite. Reaction 2 is also the first reaction in a thermo-electrochemical cycle in which magnesium and hydrogen are produced by the reactions and Reaction 4 proceeds readily at 1 atm, T > 100 degrees C, and is strongly exothermic. Consequently, in a future industrial reactor for producing hydrogen it could provide most of the heat required to form magnesite by Reaction 2. On the other hand, a substantial energy input is necessary to induce Reaction 3. If magnesite can be dissolved in a suitable low-temperature ionic liquid, this reaction could, in principle, be carried out in an electrochemical reactor, with the required energy supplied by solar cells, or by solar-powered turbines.

Because several toxicological studies indicate that trace amounts of perchlorate can cause thyroid cancer and child developmental problems, there is increasing interest in characterizing acceptable contamination levels as well as the ultimate sources of perchlorate in the environment. The stable isotope ratios of Cl and O can potentially be used to distinguish the source(s) of perchlorate in a given location and to evaluate the extent of biodegradation. The stable isotope ratios of Cl and O in anthropogenic perchlorate salts can now be readily measured in milligram amounts, but it is difficult to extract and recover isotopically measurable amounts of perchlorate from natural waters, in which perchlorate concentrations may be of the order of ppb. The recent development of a new class of bifunctional anion exchange resins for efficient sorption and removal of perchlorate, along with a new resin regeneration technique for recovering sorbed perchlorate, both developed at Oak Ridge National Laboratory, provides a means for nearly quantitative recovery of perchlorate from water samples collected in the field for isotopic analysis. Using these innovative separation-recovery technologies, we have begun a systematic characterization of the stable isotope ratios of Cl and O in perchlorate from different sources including anthropogenic perchlorate reagents, natural perchlorate-bearing salt deposits, salt-derived fertilizers, and waters from military and industrial contamination sites. Our preliminary results indicate that there are isotopic differences between various anthropogenic and natural perchlorate sources. When the data set of isotopically characterized perchlorate sources becomes sufficiently representative, stable isotope forensics of perchlorate may become useful for issues of source apportionment, natural attenuation, or monitoring of remediation efforts.

Physical and chemical properties of natural aquifer systems, such as reactive iron oxide surface area and hydraulic conductivity, are often highly heterogeneous in complex ways that can exert significant control on transport, natural attenuation, and active remediation processes. Typically, however, few data on the detailed distribution of these properties are available for incorporation into predictive models. In this study, we integrate field-scale geophysical, hydrologic, and geochemical data from a well-characterized site with the results of laboratory batch reaction studies to formulate numerical models of reactive transport in a heterogeneous granular aquifer. The models incorporate several levels of coupling, including effects of ferrous iron sorption onto (and associated reduction of reactive surface area of) ferric iron surfaces, microbial growth and transport dynamics, and cross-correlation between hydraulic conductivity and initial ferric iron surface area. These models are then used to evaluate the impacts of physical and chemical heterogeneity on transport of trace levels of uranium under natural conditions, as well as the effectiveness of uranium reduction and immobilization upon introduction of a soluble electron donor (a potential biostimulation remedial strategy).

High Ge/Si ratios in the hydrothermal fluids relative to stream waters enable the hot spring flux to be calculated on a watershed basis. As rivers cross the zone of geothermal activity, they develop anomalies in Ge/Si, K (super +) , Cl (super -) , and other solutes. 10 to 20% of the silicate derived alkalinity on the streams is derived from hydrothermal reactions. Observed spring temperatures and calculated fluxes define an overall hydrothermal heat loss in the Narayani Basin of 500 (+500/-250) MW. Fluid inclusions from hydrothermal veins that crosscut the metamorphic deformation fabric constrain temperatures near 300 degrees C and pressures near 1100 bars (Darling et al, 2002), consistent with steep geothermal gradients. The observed heat flow and geothermal gradients are consistent with a simple steady state model of crustal advection and rapid incision. Tectonically advected heat is removed quantitatively by meteoric hydrothermal circulation. A preliminary 2-D model constrains the depth and time scale of meteoric fluid circulation. MCT hot spring fluids often have high delta (super 13) C (sub DIC) , with many springs in the range of +6 to +12 per mil. The springs are supersaturated with CO (sub 2) and actively precipitate travertine. The high delta (super 13) C (sub DIC) can be modeled by a two stage process. Metamorphic decarbonation produces a (super 13) C enriched fluid phase from carbonate decomposition near 400 degrees C, up to about 4 per mil. Degassing in the near subsurface, between ca. 100 and 50 degrees C evolves a 13C-depleted gas phase, with Rayleigh enrichment of the residual DIC. Degassing of 80+ or -20% of the original CO (sub 2) is necessary to drive delta (super 13) C (sub DIC) to +8 to +12 per mil, and these values are consistent with reaction path modeling of the fluids during ascent. Comparison with the silicate alkalinity flux in local rivers implies that the magnitude of CO (sub 2) degassing is similar to the rate of CO (sub 2) uptake by silicate weathering. The net effect of high Himalayan processes on the carbon cycle may be close to zero.

Currently, conventional, statistical-mechanical calculations of molecules provide information on isolated water molecules, i.e., ideal-gas at infinitely low pressures. Furthermore, only very simplistic models are available in the literature for calculating the pressure effect on the reduced isotope partition function ratio (RIPFR) of waters at elevated pressures. We have developed a simple, yet accurate theoretical method for calculating the RIPFR of water at elevated pressures. This approach requires only accurate equations of state (EOS) for pure isotopic end-members (H (sub 2) O and D (sub 2) O), which are available in the literature. The effect of pressure or density on the RIPFR of water was calculated relative to that of ideal-gas water at infinitely low pressure for the temperature range, 0 to 527 degrees C. For gaseous and low-pressure (ca. 20 MPa) supercritical phases, the RIPFR of water decreases (2-5ppm) with increasing pressure (or density) to 100 MPa. This rather unique phenomenon is ascribed to the inverse molar volume isotope effects (MVIE) of water, V(D (sub 2) O)>V(H (sub 2) O), while other substances show the normal MVIE, including minerals. For example, at 500 degrees C we predict that D/H fractionation between a hydrous mineral (or other H-bearing substances) and water decreases by as much as 6ppm between 20 MPa and 100 MPa. These theoretical predictions were experimentally confirmed by Horita et al. (2002) for the system brucite-water. Although the P-T ranges for the EOS of normal and heavy waters are rather limited, our modeling indicates that the RIPFR of water continues to decrease with pressure above 100 MPa. These results have important implications for the interpretation of isotopic partitioning at high-pressures.

The uraninite (UO (sub 2) ) in the Okelobondo reactor zone (500 m depth) has been studied as a means by which to constrain the source term of fission product and actinides elements produced during reactor operation. The source term depends on the neutronic parameters of the reactor, which include the neutron energy spectrum, reactor flux and reactor operation duration. Reactor operation has been modeled using a point-source computer simulation (Oak Ridge Isotope Generation and Depletion, ORIGEN, code) for a light water reactor. The model results have been constrained using secondary ionization mass spectroscopy (SIMS) measurements of fission product isotopes of Nd ( (super 143) Nd, (super 144) Nd, (super 145) Nd and (super 146) Nd) and Te ( (super 125) Te, (super 126) Te, (super 128) Te and (super 130) Te), as well as U ( (super 235) U and (super 238) U) in uraninite from 18 samples distributed across a two-dimensional slice of the reactor zone. The SIMS data were corrected for instrumental mass fractionation using uraninite samples from reactor zone 10 that had been previously characterized by TIMS or ICP-MS. The isotopic compositions of fission product (e.g., (super 143) Nd/ (super 144) Nd (sub measured) =0.859 to 0.978 and (super 125) Te/ (super 128) Te (sub measured) =0.107 to 0.160) and actinide elements in the reactor zone vary significantly from terrestrial values due to fission, spontaneous fission, decay and neutron capture events that occurred during and after reactor operation. Using the constraints placed on the operating conditions by the (super 235) U/ (super 238) U ratio, the pre-reactor concentrations of Nd (150 ppm + or - 75 ppm) and Te (<1 ppm) in uraninite were determined. The final fission product inventories of Nd (90 to 1200 ppm) and Te (10 to 110 ppm) were then calculated as a function of reactor burnup (0.7 to 13.8 GWd/MTU, which corresponds to a range of (super 235) U/ (super 238) U of 0.0072 to 0.0054). Similarly, the ranges of all other fission products and actinides produced during reactor operation were calculated as a function of burnup and time. These results provide a source term against which the present elemental and decay abundances at the fission reactor can be compared. Furthermore, they provide new constraints on the extent to which a "fossil" nuclear reactor can be characterized on the basis of its isotopic signature.

We investigated artificial neural networks for analyzing the distributions of nitrite reductase genes (nirS and nirK) and two sets of dissimilatory sulfite reductase genes (dsrAB sub(1) and dsrAB sub(2)) in small sample sets. Data reduction (to reduce the number of input parameters), cross-validation (to measure the generalization error), weight decay (to adjust model parameters to reduce generalization error), and importance analysis (to determine which variables had the most influence) were useful in developing and interpreting neural network models that could be used to infer relationships between geochemistry and gene distributions. A robust relationship was observed between geochemistry and the frequencies of genes that were not closely related to known dissimilatory sulfite reductase genes (dsrAB sub(2)). Uranium and sulfate appeared to be the most related to distribution of two groups of these unusual dsrAB-related genes. For the other three groups, the distributions appeared to be related to pH, nickel, nonpurgeable organic carbon, and total organic carbon. The models relating the geochemical parameters to the distributions of the nirS, nirK, and dsrAB sub(1) genes did not generalize as well as the models for dsrAB sub(2). The data also illustrate the danger (generating a model that has a high generalization error) of not using a validation approach in evaluating the meaningfulness of the fit of linear or nonlinear models to such small sample sizes.

The primers were specific to copper-dependent nitrite reductase gene (nirK). We were able to detect about 200 copeis of nirK in the presence of abundant non-specific target DNA and about 1.2x10 super(3) Pseudomonas sp. G-179 cells from one gram of sterilized soil by PCR amplification. A 312-bp nirK internal standard (IS) was constructed, which showed very similar amplification efficiency with the target nirKfragment (349 bp) over 4 orders of magnitude (10 super(3)-10 super(6)). The accuracy of this system was evaluated by quantifying various known amount of nirK DNA. The linear regressions were obtained with a R super(2) of 0.9867 for 10 super(3)copies of nirK, 0.9917 for 10 super(4) copies of nirK, 0.9899 for 10 super(5) copies of nirK and 0.9846 for 10 super(6) copies of nirK. A high correlation between measured nirK and calculated nirK (slope of 1.0398, R super(2)=0.9992) demonstrated that an accurate measurement could be achieved with this system. Using this method, we quantified nirK in several A-horizon and stream sediment samples from eastern Tennessee. In general, the abundance of nirK was in the range of 10 super(8)-10 super(9) copies g soil super(-) super(1) dry weight. The nirK content in the soil samples appeared correlated with NH sub(4)(N) content in the soil. The activities of copper-denitrifying bacteria were evaluated by quantifying cDNA of nirK. In most of sample examined, the content of nirK cDNA was less than 10 super(5) copies g soil super(-) super(1) dry weight. Higher nirK cDNA content (>10 super(6) copies g soil super(-) super(1) dry weight) was detected from both sediment samples at Rattlebox Creek and the Walker Branch West Ridge. Although the stream sediment samples at the Walker Branch West Ridge contained less half of the nirK gene content as compared to A-horizon sample, the activities of copper-denitrifying bacteria were almost 600 times higher than in the A-horizon sample.

Of the protein- coding genes (open reading frames [ORFs]), 44% were assigned a function, 48% were conserved but had unknown or uncertain functions, and 7.5% (129 ORFs) were unique to M. maripaludis. Of the unique ORFs, 27 were confirmed to encode proteins by the mass spectrometric identification of unique peptides. Genes for most known functions and pathways were identified. For example, a full complement of hydrogenases and methanogenesis enzymes was identified, including eight selenocysteine-containing proteins, with each being paralogous to a cysteine-containing counterpart. At least 59 proteins were predicted to contain iron-sulfur centers, including ferredoxins, polyferredoxins, and subunits of enzymes with various redox functions. Unusual features included the absence of a Cdc6 homolog, implying a variation in replication initiation, and the presence of a bacterial-like RNase HI as well as an RNase HII typical of the ARCHAEA: The presence of alanine dehydrogenase and alanine racemase, which are uniquely present among the Archaea, explained the ability of the organism to use L- and D-alanine as nitrogen sources. Features that contrasted with the related organism Methanocaldococcus jannaschii included the absence of inteins, even though close homologs of most intein-containing proteins were encoded. Although two-thirds of the ORFs had their highest Blastp hits in Methanocaldococcus jannaschii, lateral gene transfer or gene loss has apparently resulted in genes, which are often clustered, with top Blastp hits in more distantly related groups.

At each temperature, separate functions are used to represent the bubble- and dew-point boundary curves that: originate at the saturation vapor pressure of water (P (super H2O) (sub sat) ) at X (sub CO2) = 0; diverge with increasing pressure up to approximately P (X (super max) (sub CO2) ) where delta P/delta X (sub CO2) = +infinity along the dew-point curve; then converge with increasing pressure above P(X (super max) (sub CO2) ). At temperatures below 265 degrees C and pressures >P(X (super max) (sub CO2) ), the compositions of coexisting liquid and vapor [X (super L(V)) (sub CO2) ] and X (super V(L)) (sub CO2) ] do not converge completely with increasing pressure due to the absence of critical behavior. Thus, relatively simple functions suffice to accurately represent VLE at those temperatures. In contrast, at T>265 degrees C, X (super L(V)) (sub CO2) and X (super V(L)) (sub CO2) converge rapidly as P approaches P (sub c) (the critical pressure in the CO (sub 2) -H (sub 2) O system at a given temperature between 265 and 374 degrees C and P< or =215 MPa). For those temperatures, therefore, more complex VLE formulae are required to achieve close representation of phase relations. For dew-point equations, this includes adding an exponential "correction term" to ensure that delta P/delta X (sub CO2) = 0 at the critical points indicated by corresponding bubble-point functions. Stable liquid-vapor coexistence in mixed-volatile systems requires f (super L) (sub i) = f (super V) (sub I) (isofugacity conditions) for all "i" (volatile components) in the two fluid phases. Thus, the equations presented in this paper specify numerous P-T-X conditions where f (super L) (sub H2O) = f (super V) (sub H2O) and f (super L) (sub CO2) in the CO (sub 2) -H (sub 2) O system. These results have important applications in the ongoing effort to develop a more rigorous thermodynamic model for CO (sub 2) -H (sub 2) O fluids at geologically relevant temperatures and pressures.

The data were collected in part to address concerns about possible undocumented hazardous waste sites. Interpretation of the aeromagnetic data was complicated, however, by the discovery in remote areas of numerous small magnetic anomalies of natural origin. Magnetic susceptibility measurements of core showed that the underlying Copper Ridge Dolomite was non-magnetic. We attribute the magnetic anomalies to the presence of the ferromagnetic mineral maghemite (gamma -Fe (sub 2) O (sub 3) ), which formed during pedogenesis of Fe-enriched colluvium that had infilled low-lying areas, including dolines. We discuss explanations offered in the literature for the formation of magnetic soils, and present evidence based on profile descriptions, thin sections, x-ray diffraction (XRD), and scanning electron microscopy (SEM), that in this case, maghemite formed either by anaerobic microbial Fe reduction followed by the formation of single-domain maghemite, or by abiological weathering and reduction of an Fe-bearing mineral followed by oxidation. Naturally occurring magnetic soils may produce magnetic anomalies similar to those characteristics of anthropogenic objects, such as buried waste drums, and complicate interpretation of airborne geophysical surveys.

Biodegradation, photolysis, and any other process that can be modeled using a first-order decay constant can be included as well. HYTRAS originally modeled the transport of radionuclides and has recently been expanded to include transport of chemicals. The transport of chemicals has been validated using data from an accidental release of the chemicals disulfoton and thiometon into the Rhine River in 1986. For these chemicals, sorption is not an important process. For the range of measured flow velocities, HYTRAS was found to bound the peak arrival times. For the range of measured degradation rates, HYTRAS was found to bound the peak concentrations within 400 km of the source and bound the peak concentrations within a factor of two out to 700 km.

ER - TY - JOUR T1 - Composition and Diversity of Microbial Communities Recovered from Surrogate Minerals Incubated in an Acidic Uranium-Contaminated Aquifer AN - 19939796; 6040293 AB - Our understanding of subsurface microbiology is hindered by the inaccessibility of this environment, particularly when the hydrogeologic medium is contaminated with toxic substances. In this study, surrogate geological media contained in a porous receptacle were incubated in a well within the saturated zone of a pristine region of an aquifer to capture populations from the extant communities. After an 8-week incubation, the media were recovered, and the microbial community that developed on each medium was compared to the community recovered from groundwater and native sediments from the same region of the aquifer, using 16S DNA coding for rRNA (rDNA)-based terminal restriction fragment length polymorphism (T-RFLP). The groundwater and sediment communities were highly distinct from one another, and the communities that developed on the various media were more similar to groundwater communities than to sediment communities. 16S rDNA clone libraries of communities that developed on particles of a specular hematite medium incubated in the same well as the media used for T-RFLP analysis were compared with those obtained from an acidic, uranium- contaminated region of the same aquifer. The hematite-associated community formed in the pristine area was highly diverse at the species level, with 25 distinct phylotypes identified, the majority of which (73%) were affiliated with the beta-PROTEOBACTERIA: Similarly, the hematite-associated community formed in the contaminated area was populated in large part by beta-Proteobacteria (62%); however, only 13 distinct phylotypes were apparent. The three numerically dominant clones from the hematite-associated community from the contaminated site were affiliated with metal- and radionuclide-tolerant or acidophilic taxa, consistent with the environmental conditions. Only two populations were common to both sites.

To promote consistency and an appropriate level of safety, these detailed requirements are based on the Regulations for the Safe Transport of Radioactive Material, developed by the International Atomic Energy Agency. The development and application of these regulations illustrate how international cooperation has led to effective transport-safety requirements that remain technically up-to-date and ensure an appropriate level of safety for all modes of transport.

AN - 67192613; 15619958 AB - By means of the mouse specific-locus test (SLT) with visible markers, which is capable of detecting intragenic mutations as well as larger lesions, about 20 mutagens have been studied comparatively across arrays of male germ-cell stages. In addition, a very large historical control, accumulated over decades, provides data on spontaneous mutations in males. Each mutagen has a characteristic germ-cell-stage sensitivity pattern. Although most chemicals yield their maximum numbers of mutations following exposure of spermatozoa and late spermatids, mutagens have now been identified that peak in each of the major stages of spermatogenesis and spermiogenesis, including those in which effects on recombination can also be induced. Stem-cell spermatogonia have yielded positive results with only five of 15 mutagenic chemicals. In postspermatogonial stages, all chemicals, as well as radiations, induce primarily large lesions (LL). By contrast, in spermatogonia (either stem-cell or differentiating) all chemicals except one (bleomycin) produce very few such lesions. The spectrum of relative mutation frequencies at the seven loci of the SLT is characteristic for treated germ-cell stage and mutagen. Treatments that induce primarily LL are characterized by a great preponderance of s (Ednrb)-locus mutations (possibly due to a paucity of haplo-insufficient genes in the surrounding region); and those that induce very few, if any, LL by a great preponderance of p-locus mutations. Spontaneous locus-spectra differ from both types of treatment-induced spectra; moreover, there are two distinct types of spontaneous spectra, depending on whether mutations occurred in mitotic cells or during the perigametic interval.

AN - 67029712; 15520889 AB - Net environmental benefits are gains in value of environmental services or other ecological properties attained by remediation or ecological restoration minus the value of adverse environmental effects caused by those actions. Net environmental benefit analysis (NEBA) is a methodology for comparing and ranking net environmental benefits associated with multiple management alternatives. A NEBA for chemically contaminated sites typically involves comparison of several management alternatives: (1) leaving contamination in place; (2) physically, chemically, or biologically remediating the site through traditional means; (3) improving ecological value through onsite and offsite restoration alternatives that do not directly focus on removal of chemical contamination; or (4) a combination of those alternatives. NEBA involves activities that are common to remedial alternatives analysis for state regulations and the Comprehensive Environmental Response, Compensation, and Liability Act, post-closure and corrective action permits under the Resource Conservation and Recovery Act, evaluation of generic types of response actions pertinent to the Oil Pollution Act, and land management actions that are negotiated with regulatory agencies in flexible regulatory environments (i.e., valuing environmental services or other ecological properties, assessing adverse impacts, and evaluating remediation or restoration options). This article presents a high-level framework for NEBA at contaminated sites with subframeworks for natural attenuation (the contaminated reference state), remediation, and ecological restoration alternatives. Primary information gaps related to NEBA include nonmonetary valuation methods, exposure-response models for all stressors, the temporal dynamics of ecological recovery, and optimal strategies for ecological restoration.

We applied this method to the investigation of the dynamic process of clathrate hydrate precipitation from CO (sub 2) solution using a high-pressure dissolution system consisting of a high-pressure vessel and optical detecting instruments. The role of stirring was examined. The temperatures studied in the experiments were from 275 to 288 K over a pressure range of 4-8 MPa. Experimental results showed that our method can quantitatively monitor this dynamic process. The volume ratio of precipitated hydrate to that of the pressure-vessel approached 0.09 when a steady state was reached, which took about 100 seconds; more than 60% of the total clathrate hydrate precipitated within 10 seconds at the cooling rates of this experiment. For precipitation, stirring enhanced the cooling and led to a large hydrate precipitation rate from 0.004 to 0.008 in volume ratio per second. For nucleation, however, the residual structure of the solution decreased the amount of hysteresis in the formation of hydrate nuclei during supercooling, of which induction times were reduced by 4-9 minutes.

Our compressional wave speed measurements through partially water-saturated, methane hydrate-bearing Ottawa sands suggest hydrate surrounds and cements sediment grains. The three Ottawa sand packs tested in the Gas Hydrate And Sediment Test Laboratory Instrument (GHASTLI) contain 38(1)% porosity, initially with distilled water saturating 58,31, and 16% of that pore space, respectively. From the volume of methane gas produced during hydrate dissociation, we calculated the hydrate concentration in the pore space to be 70,37, and 20% respectively. Based on these hydrate concentrations and our measured compressional wave speeds, we used a rock physics model to differentiate between potential pore-space hydrate distributions. Model results suggest methane hydrate cements unconsolidated sediment when forming in systems containing an abundant gas phase.

Several samples of methane hydrate were also quenched after various extents of partial reaction for assessment of mid-synthesis textural progression. All laboratory-synthesized hydrates were grown under relatively high-temperature and high-pressure conditions from rounded ice grains with geometrically simple pore shapes, yet all resulting samples displayed extensive recrystallization with complex pore geometry. Growth fronts of mesoporous methane hydrate advancing into dense ice reactant were prevalent in those samples quenched after limited reaction below and at the ice point. As temperatures transgress the ice point, grain surfaces continue to develop a discrete "rind" of hydrate, typically 5 to 30 mu m thick. The cores then commonly melt, with rind microfracturing allowing migration of the melt to adjacent grain boundaries where it also forms hydrate. As the reaction continues under progressively warmer conditions, the hydrate product anneals to form dense and relatively pore-free regions of hydrate grains, in which grain size is typically several tens of micrometers. The prevalence of hollow, spheroidal shells of hydrate, coupled with extensive redistribution of reactant and product phases throughout reaction, implies that a diffusion-controlled shrinking-core model is an inappropriate description of sustained hydrate growth from melting ice. Completion of reaction at peak synthesis conditions then produces exceptional faceting and euhedral crystal growth along exposed pore walls. Further recrystallization or regrowth can then accompany even short-term exposure of synthetic hydrates to natural ocean-floor conditions, such that the final textures may closely mimic those observed in natural samples of marine origin. Of particular note, both the mesoporous and highly faceted textures seen at different stages during synthetic hydrate growth were notably absent from all examined hydrates recovered from a natural marine-environment setting.

In situ observations of the formation of porous CH (sub 4) - and CO (sub 2) -hydrates from deuterated ice Ih powders were made at different pressures and temperatures, using time-resolved neutron diffraction data from the high-flux D20 diffractometer (ILL, Grenoble) as well as in-house gas consumption measurements. The CO (sub 2) experiments conducted at low temperatures are particularly important for settling the open question of the existence of CO (sub 2) hydrates on Mars. We found that at similar excess fugacities, the reaction of CO (sub 2) was distinctly faster than that of CH (sub 4) . A phenomenological model for the kinetics of the gas hydrate formation from powders of spherical ice particles is developed with emphasis on ice-grain fracturing and sample-consolidation effects due to the outward growth of gas hydrate. It describes (1) the initial stage of fast crack-filling and hydrate film spreading over the ice surface and the two subsequent stages which are limited by (2) the clathration reaction at the ice-hydrate interface and/or by (3) the diffusive gas and water transport through the hydrate shells surrounding the shrinking ice cores. In the case of CO (sub 2) -hydrate, the activation energies of the ice-surface coating in stage 1 are estimated to be 5.5 kJ/mol at low temperatures and 31.5 kJ/mol above 220 K, indicating that water molecule mobility at the ice surface plays a considerable role in the clathration reaction. Comparable activation energies of 42.3 and 54.6 kJ/mol are observed in the high temperature range for the reaction- and diffusion-limited stages 2 and 3, respectively.

The model uses the Valderrama modification of the Patel and Teja Equation of State (VPT EoS) for fugacity calculations in fluid phases, while the hydrate phase is modeled using the solid solution theory of van der Waals and Platteeuw (1959), as implemented by Cole and Goodwin (1990). The Kihara model for spherical molecules is applied to calculate the potential function for hydrate-forming gases. To account for capillary pressure effects on phase fugacities, we apply a correction similar to the Poynting correction for saturated liquids. This correction can be applied to any model capable of predicting bulk (unconfined) hydrate phase equilibria. The only new parameter required is hydrate-liquid interfacial tension-values for which we have derived previously from experimental data. The model assumes cylindrical pores, although differs from the majority of existing literature models in how the curvature of the solid-liquid interface is considered; we assume a curvature of 2/r for growth and 1/r for dissociation, in accordance with accepted capillary theory. Model predictions are validated against previously published experimental hydrate dissociation data for binary CO (sub 2) -H (sub 2) O, CH (sub 4) -H (sub 2) O and ternary CH (sub 4) -CO (sub 2) -H (sub 2) O systems, and newly reported data for CH (sub 4) -H (sub 2) O-CH (sub 4) O (3.5 mass% methanol aqueous solutions representing the salinity of seawater) systems, confined to mesoporous silica glass. Good agreement between predictions and experimental data is observed.

Hydrate formation experiments were performed in a 72 L pressure vessel by injecting bubbles of carbon dioxide through a 1 L tube at hydrate formation pressures (1.4 to 3.7 Mpa) and temperatures (2 to 5 degrees C). The results revealed that when even a small fraction (e.g., 5-35%) of the water in which the hydrate formed was recently thawed the overpressure for nucleation was reduced by an average of 50% as compared to untreated distilled water. This observation was confirmed by an analysis of variance (ANOVA) test that indicated that recently thawed water required a significantly lower overpressure compared to the untreated distilled water. In experiments where hydrate nucleated at low overpressure (e.g., 0.75 MPa), hydrate formed at the vapor-liquid interface, encrusting the bubbles with less than 1 g of hydrate accumulation in the first minute. When a higher overpressure was required for nucleation (e.g., 1.3 MPa), hydrate was observed to form abruptly not only on bubbles but also from the bulk liquid phase, typically accumulating a mass of more than 100 g in the first few seconds. Our results show that initiation of hydrate formation is strongly influenced by temperature-dependent pre-structuring of water molecules prior to their contact with gas. Although as little as a 5% volume fraction of pre-structured water may decrease the required overpressure, once hydrate formation commences the mass of hydrate accumulation is dependent on the overpressure.

Under high-pressure and low-temperature conditions, the jet breakup patterns follow distinct Rayleigh, transitional, and spray modes. Droplet size distribution was determined in the different modes, with the spray mode producing the smallest droplets and the most uniform size distribution. The system appears to progress from transitional to spray mode when the Ohnesorge number is approximately 18 Re (super -1) . Using this relationship, it is possible to predict the minimum injection rate necessary for spray mode at any injector diameter. Under hydrate-forming conditions, the jet breakup did not appear to be affected because breakup occurred faster than hydrate formation. However, injection into a confined space could promote droplet coalescence, resulting in a larger average drop size. These results can be used to control hydrate conversion in an ocean CO (sub 2) injection system and to ensure a large dispersion of injected CO (sub 2) during its sequestration in the ocean.

After an initial motivation section with hydrate applications, the hydrate structure are exposed, by considering two formation heuristics. Second, the history of hydrate knowledge both within and without the pipeline is outlined, and examples are given of technology transfer between the two arenas. The hydrate experimental physics and chemistry are then presented on three levels: micro-, meso-, and macroscopic. Finally it is suggested that the state-of-the-art of hydrate thermodynamics is satisfactory for most engineering applications, because the prediction accuracy is close to the experimental accuracy. Hydrate kinetics, on the other hand, is presented as a major physico-chemical challenge for the future.

The results from these kinetic measurements were compared to those obtained from gas hydrate studies. The thermodynamic inhibitory nature of methanol was reflected in the findings as expected. However, some nucleation retardation was also observed at all concentrations studied, with higher concentrations of methanol resulting in ice formation. Addition of poly-N-vinylpyrrolidone (PVP) to THF/water mixtures caused nucleation times to increase and crystal growth to decelerate. No significant synergic effect was observed for THF hydrate inhibition using a combination of PVP and one of two glycol ethers, which were found to dramatically increase nucleation periods in natural gas hydrate formation. Only a slight synergic tendency was observed for the combination from the DSC results, while the Raman data gave no indication of a synergic effect for the combination. The results suggest that the nature of the guest species may be an important factor in the mechanism of hydrate inhibition.

These measurements show that hydrate increases shear strength and p-wave velocity in natural and reconstituted samples. The proportion of this increase depends on (1) the amount and distribution of hydrate present, (2) differences in sediment properties, and (3) differences in test conditions. Stress-strain curves from the Mallik samples suggest that natural gas hydrate does not cement sediment grains. However, stress-strain curves from the Ottawa sand (containing laboratory-formed gas hydrate) do imply cementation is present. Acoustically, rock physics modeling shows that gas hydrate does not cement grains of natural Mackenzie Delta sediment. Natural gas hydrates are best modeled as part of the sediment frame. This finding is in contrast with direct observations and results of Ottawa sand containing laboratory-formed hydrate, which was found to cement grains (Waite et al. 2004). It therefore appears that the microscopic distribution of gas hydrates in sediment, and hence the effect of gas hydrate on sediment physical properties, differs between natural deposits and laboratory-formed samples. This difference may possibly be caused by the location of water molecules that are available to form hydrate. Models that use laboratory-derived properties to predict behavior of natural gas hydrate must account for these differences.

Two regimes of guest dynamics have been identified in the range 10 K to 100 K. Below 50 K, the hydrogen atoms on TMO execute jumps between nonequivalent sites with a jump distance of 2.1 A, consistent with a model of rotations of 90 degrees about the C (sub 2V) molecular axis between sites with unequal occupancy probabilities, and corresponding to an energy difference between sites of approximately 7 me V. Above 50 K, a second dynamical regime appears in which rotational motions of H occur about both the C (sub 2V) axis and a second axis perpendicular to the plane of the molecule. An increase in the activation energy barrier to the motion that appears to accompany the onset of multi-axis motion could be a result of the additional high-energy rotations taking place within more restricted cross sections of the cage.

AN - 51794113; 2004-076545 AB - Kinetic studies are reported of the effect of methanol on the rate of formation of CO (sub 2) - and CH (sub 4) -hydrates by means of in situ time-of-flight neutron powder diffraction. The experiments were carried out at temperatures ranging from 200 to 250 K and pressures up to 7 Mpa. The samples were prepared from mixtures of ground, deuterated ice and deuterated methanol (up to 20 vol%), which were transformed in situ into CO (sub 2) - or CH (sub 4) -hydrates by pressurizing the systems with the corresponding gas. The observed rates of formation of hydrates are orders of magnitude higher than the rate of formation from pure deuterated ice under the same pressure and temperature conditions. Glycols and alcohols, methanol in particular, are long known as thermodynamic inhibitors of hydrate formation. Our study indicates that methanol can also act as a kinetic promoter for the formation of gas hydrates. Preliminary data suggest that the kinetics also depend strongly on concentration and the isotopic composition.

The changes may result from varying pressure or temperature at the seafloor, exploration and exploitation operations, rapid sedimentation or wasting at the seafloor, etc. Pressure and temperature may not be used as independent state variables at the same time to specify the overall state of such dynamic systems. Consequently, a pressure-enthalpy-gas concentration-salinity phase balance model is constructed for calculating phase distribution and transition of the system of marine gas hydrate, which is assumed to contain a liquid phase consisting of water, gas, and salt, a vapor phase consisting of gas only, solid halite, and solid gas hydrate consisting of gas and water. Calculations of phase transition processes demonstrate various dynamic feedback mechanisms involved in dynamically evolving marine gas-hydrate systems. A comprehensive model of fluid flow and transport of heat, water, salt, and gas in marine sediment is developed. Simulations show that gas hydrate dissociation resulting from increasing temperature or decreasing pressure at the seafloor may lead to the development of a three-phase zone with coexistent gas hydrate, free gas, and liquid solution and excess pore pressure in marine gas hydrate systems. The changes considered in this study are rapid (1- (super -2) years) to allow thermodynamic equilibrium throughout. The applicable pressure, temperature, and salinity ranges for the calculations used in this study are sufficiently wide to cover those likely occurring in gas hydrate-bearing marine sediments.

By experimentally studying the conditions under which such a CO (sub 2) gas hydrate film maintains a constant thickness, we determined the processes that control CO (sub 2) hydrate growth rates. A constant film thickness cannot be maintained when the decomposition rate exceeds a certain critical value. The decomposition rate was varied by adjusting the flow velocity of a water stream directed perpendicular to the hydrate film. An increase of the flow speed increased the decomposition rate, which decreased the steady-state film thickness. However, at a critical value, net decomposition occurs and the hydrate film completely dissolves. The critical decomposition rates are roughly proportional to pressure and relatively independent of temperature from 274.6 to 278.7 K. The transport of H (sub 2) O through the hydrate layer to the growth sites near the CO (sub 2) -hydrate interface controls the growth rate when it is relatively small, but the supply of CO (sub 2) molecules limits it at relatively high growth rates.

The dissociation rate decreases with increasing pressure at a given temperature. Dissociation rates at 1.0 MPa parallel the complex, reproducible T-dependence previously observed between 250 and 272 K at 0.1 MPa. The lowest rates were observed near 268 K, such that >50% of the sample can persist for more than two weeks at 0.1 MPa to more than a month at 1 and 2 MPa. Varying the pressure stepwise in a single experiment increased or decreased the dissociation rate in proportion to the rates observed in the isobaric experiments, similar to the rate reversibility previously observed with stepwise changes in temperature at 0.1 MPa. At fixed P, T conditions, the rate of methane hydrate dissociation decreases monotonically with time, never achieving a steady rate. The relationship between time (t) and the extent of hydrate dissociation is empirically described by: Evolved gas (%) = A.t (super B) where the pre-exponential term A ranges from 0 to 16% s (super -B) and the exponent B is generally <1. Based on fits of the dissociation results to Equation 1 for the full range of temperatures (204 to 289 K) and pressures (0.1 to 2.0 MPa) investigated, the derived parameters can be used to predict the methane evolution curves for pure, porous methane hydrate to within + or -5%. The effects of sample porosity and the presence of quartz sand and seawater on methane hydrate dissociation are also described using Equation 1.

Experimental results are in good agreement with available data, and concord well with predictions computed using the model of Van der Waals and Platteeuw (1959). DSC experiments revealed eutectic melting of solid mixtures of gas hydrate and crystallized salt. Corresponding invariant temperatures of melting and phase compositions were computed for various gas pressures. Complete phase diagrams are proposed for the systems (methane+water+sodium chloride) and (methane+water+calcium chloride) at 2 MPa and 10 MPa methane pressure.

We have performed experiments on H (sub 2) O-CO (sub 2) -NaCl fluids at 500 degrees C, 500 bar, to obtain accurate and precise data on their a-X relations and phase equilibria. Two kinds of experiments were performed. First, H (sub 2) O-CO (sub 2) -NaCl samples were reacted at fixed activities of H (sub 2) O = 0.078, 0.350, 0.425, 0.448, 0.553, 0.560, 0.606, 0.678, 0.798, 0.841, and 0.935 to define the tie lines of known H (sub 2) O activity in the halite-vapor and vapor-brine fields. Results indicate that fluids with all but the last of these H (sub 2) O activities lie in the vapor-halite two-phase region and that a fluid with a (sub H (sub 2) O) = 0.841 has a composition close to the three-phase (vapor + brine + halite) field. A second set of experiments was performed to determine the solubility of NaCl in parts of the system in equilibrium with halite. Data from these experiments suggest that the vapor corner of the three-phase field lies at H (sub 2) O contents above X (sub H (sub 2) O) = 0.58 and X (sub NaCl) = 0.06, and below X (sub H (sub 2) O) = 0.75 and X (sub NaCl) = 0.06, which is a significantly more H (sub 2) O-rich composition than indicated by existing thermodynamic models.

We selected three reaction pathways to investigate fractionation: (a) reaction of fine-grained magnetite with dilute aqueous NaCl solutions; (b) reduction of fine-grained hematite through reaction with dilute acetic acid; and (c) oxidation of fine iron power in either pure water or dilute NaCl solutions. Effective use of acetic acid was limited to temperatures up to about 400 degrees C, whereas oxide-solution isotope exchange experiments were conducted at all temperatures. Equilibrium (super 18) O/ (super 16) O fractionation factors were calculated from the oxide-water experiments by means of the partial isotope exchange method, where generally four isotopically different waters were used at any given temperature. Each run product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and on a limited basis, high-resolution transmission electron microscopy (HRTEM) and Mossbauer spectroscopy. Results from the microscopic examinations indicate the formation of well-crystallized octahedra and dodecahedra of magnetite where the extent of crystallization, grain size, and grain habit depend on the initial starting material, P, T, solution composition, and duration of the run.The greatest amount of oxygen isotope exchange ( approximately 90% or greater) was observed in experiments where magnetite either recrystallized in the presence of 0.5 m NaCl from 500 to 800 degrees C or formed from hematite reacted with 0.5 m acetic acid at 300, 350 and 400 degrees C. Fractionation factors (10 (super 3) ln alpha (sub mt-H2) (sub O) ) determined from these partial exchange experiments exhibit a steep decrease (to more negative values) with decreasing temperature down to about 500 degrees C, followed by shallower slope. A least-squares regression model of these partial exchange data, which accounts for analytical errors and errors generated by mass balance calculations, gives the following expression for fractionation that exhibits no minimum: 1000 lnalpha (sub lmt-lw) = -8.984(+ or -0.3803)x+3.302(+ or -0.377)x (super 2) - 0.426(+ or -0.0 92)x (super 3) with an R (super 2) = 0.99 for 300 or =500 degrees C, but differ significantly with estimates based on quasi-theoretical and empirical approaches. Calcite-magnetite and quartz-magnetite fractionation factors estimated from the combination of magnetite beta "s calculated in this study with those for calcite and quartz reported by Clayton and Kieffer (1991) agree very closely with experimentally determined mineral-pair fractionations.

Over the period from 1991 to 2002, there was a slight declining trend in watershed export of dissolved inorganic N via streamflow, despite relatively high and constant wet N deposition rates (5 kg/ha/y). The watershed retains >90% of N deposition inputs. Concentrations of NO sub(3) super(-) and soluble reactive phosphorus (SRP) showed distinct seasonal patterns with autumn and early spring minima and summer maxima. An end-member mixing analysis indicated that these seasonal concentration patterns were largely a result of seasonal variations in in-stream uptake processes, with net uptake of NO sub(3) super(-) and SRP having the greatest impact on streamwater concentrations in November (reductions of 29 mu g N/l and 2.5 mu g P/l, respectively). This was likely a result of high rates of uptake by microbes colonizing new inputs of leaf detritus. For NO sub(3) super(-) there was a secondary peak in net uptake in March and April (about 9 mu g N/l) resulting from increased uptake by stream algae and bryophytes. Summer was a period of net release of NO sub(3) super(-) to streamwater (peaking at 9 mu g N/l in July) and minimal net effects on SRP concentrations. On average, in-stream processes resulted in removal of about 20% of the NO sub(3) super(-) and 30% of the SRP entering the stream from the catchment annually. This study, as well as other recent work, suggests that in-stream processes are important buffers on stream nutrient concentrations and exports reducing the effects of changes in inputs and retention in terrestrial portions of watersheds.

Methods to improve throughput of RNA isolation from tissues are needed. The effects of bead size and composition for disrupting mouse tissues have been evaluated in small centrifuge tubes and optimized for RNA production. The resulting process is inexpensive, resistant to cross-contamination, and amenable to robotic processing. After optimization, very-high-quality RNA can be produced. Comparisons between RNAs isolated by beadmilling (followed by solid-phase purification) and those by conventional isolation processes show that RNA produced by beadmilling is suitable for microarray analyses. Parallel implementation of beadmilling will enable a high-throughput tissue-to-RNA processing system for large-scale microarray analyses.

J. Torrey Bot. Soc. 131: 204-219. 2004.-Combining dendrochronological and documentary reconstructions, this paper investigates the history of the forests at James Madison's Montpelier plantation in the Virginia piedmont from their earliest written account in 1716 through the designation of a National Natural Landmark (NNL) forest in 1987. This forest, informally known as the 'Big Woods,' currently features a live basal area of 43.06 +/-3.44 m super(2) . ha super(-1) (95% Confidence limits) and is dominated by Liriodendron tulipifera, Carya, and Quercus species. Quercus alba tree rings from both the NNL forest and from a forest on Mount Emerson, also located within Montpelier, are used to generate two separate, canopy-disturbance chronologies dating to the early 1700s. Additionally, ages of Q. alba and other tree species provide estimates of decadal establishment in both forests. Comparing these dendrochronological reconstructions of forest history with an analysis of letters and descriptive information from the Madison family and more recent landowners clarifies both the timing and relative magnitude of disturbance and establishment events set forth by the documentary reconstructions. Furthermore, this comparison also reveals that disturbance and establishment events in these two forests frequently coincide with changes in land use and ownership with notable canopy disturbances occurring in 1749, 1880s, 1920s, and 1987 and an establishment episode in the mid-1800s. These events have most likely increased the dominance of L. tulipifera; however, both forests still retain trees that pre-date Madison-family settlement.

Based on partial small-subunit (SSU) rRNA gene sequences (approximately 500 nucleotides), six isolates shared 98.9% nucleotide identity. As a representative, the isolate QYMF was selected for further analysis. QYMF could be grown with Fe(III)-citrate, Fe(III)-EDTA, Co(III)-EDTA, or Cr(VI) as electron acceptors, and yeast extract and lactate could serve as electron donors. Growth during iron reduction occurred over the pH range of 7.5 to 11.0 (optimum, pH 9.5), a sodium chloride range of 0 to 80 g/liter (optimum, 20 g/liter), and a temperature range of 4 to 45 degree C (optimum, approximately 35 degree C), and iron precipitates were formed. QYMF was a strict anaerobe that could be grown in the presence of borax, and the cells were straight rods that produced endospores. Sodium chloride and yeast extract stimulated growth. Phylogenetic analysis of the SSU rRNA gene indicated that the bacterium was a low-G+C gram-positive microorganism and had 96 and 92% nucleotide identity with Alkaliphilus transvaalensis and Alkaliphilus crotonatoxidans, respectively. The major phospholipid fatty acids were 14:1, 16:1 omega 7c, and 16:0, which were different from those of other alkaliphiles but similar to those of reported iron-reducing bacteria. The results demonstrated that the isolate might represent a novel metal-reducing alkaliphilic species. The name Alkaliphilus metalliredigens sp. nov. is proposed. The isolation and activity of metal- reducing bacteria from borax-contaminated leachate ponds suggest that bioremediation of metal-contaminated alkaline environments may be feasible and have implications for alkaline anaerobic respiration.

II. Mercury depletion AN - 16183734; 6000190 AB - Simulations of atomic mercury depletion episodes in the polar spring are now based largely on Br sub(2) and Br-atom initiated chemistry. Chlorine is believed to contribute little to the observed depletion. The role, if any, that the presence of iodine compounds play in Hg-atom depletion is unknown at present. The theoretically predicted instability of the HgI species suggests that I-atom reactions with mercury may be an unimportant loss process. However, iodine atoms react rapidly with ozone to develop IO radicals that interact with BrO radicals to enhance Br- and I-atom concentrations, so an indirect influence of iodine compounds on Hg removal might be expected. Computer simulations are described in this study that test this hypothesis using the homogeneous portion of the chemistry of the mercury depletion in the troposphere. Conditions are chosen equivalent to the 1300-1400 h on a clear day (17 March) at the location of Barrow, Alaska (Atmos. Environ. 37 (2003) 4467). Small amounts of reactive trace gases, representative of the Arctic spring, are present initially with typical background levels of Hg (0.24 ppt) and 50 ppb of O sub(3). The simulations show that gaseous atomic mercury depletion in typical Br sub(2) and BrCl mixtures can be enhanced significantly by the presence of small amounts of iodine-containing compounds (I sub(2), CH sub(2)I sub(2), CH sub(2)IBr, CH sub(2)ICl, IBr, and ICl). The major initial product of the possible mercury reactions is HgBr. The subsequent coupling reactions of this species with Br, BrO, Cl, ClO, I, IO, and OH radicals are expected to lead to a variety of reactive gaseous mercury-containing products.

I. Ozone depletion AN - 16183705; 6000188 AB - Iodine in the atmosphere, identified largely by the presence of IO, is a ubiquitous component of the troposphere in coastal and oceanic areas. The role, if any, that iodine chemistry plays in the polar ozone depletion episodes is not known. These events are rationalized today largely in terms of Br sub(2)- and BrCl-initiated reactions. The potential for enhancement of ozone depletions through the presence of iodine-containing molecules (I sub(2), IBr, ICl, CH sub(2)I sub(2), CH sub(2)IBr, CH sub(2)ICl, and CH sub(3)I) is investigated in this study. Computer simulations of the homogeneous chemistry are made using a reasonably complete reaction mechanism for Br-, Cl- and I-containing species together with representative chemistry of trace gases in the clean troposphere. The extent of uncertain alternative pathways and efficiencies for OIO and I sub(2)O sub(2) photolyses are varied over a range of possible values to establish the sensitivity of the depletion events to these variables. The study shows that significant enhancements of the polar ozone depletion are expected when small amounts of iodine-containing compounds such as CH sub(2)I sub(2), IBr, or ICl are present in a polar air mass containing representative Br sub(2)-BrCl-trace gas mixtures. The synergistic effect of the iodine compounds results from additional halogen-atom formation from IO-IO, IO-BrO, and IO-ClO reactions. Measurements of IO and precursor iodine-containing compounds are encouraged for future polar spring studies, as well as currently acknowledged important trace species (O sub(3), CH sub(2)O, BrO, Br sub(2), and BrCl).

AN - 85288026; pmid-15376666 AB - The problem of determining the shape of an acoustically hard scattering object from remote scattering measurements is considered. An iterative approach is used to find the object shape that minimizes the mean-squared difference between a set of actual and predicted scattering observations. A crucial task in this minimization is the computation of the "shape derivative," or functional gradient, of the mean-square error with respect to the object's shape or boundary. The shape derivative tells us how to update the object's shape to reduce the mean-square error at each iteration. If, for example, the object's boundary is parameterized with N variables, a brute-force approach to computing the shape derivative using finite-differences would require a minimum of N+1 forward solutions per iteration. We show how the shape derivative can be computed with just two forward solutions: one ordinary forward solution and a suitably constructed adjoint solution. This approach is independent of N and is not only far more efficient, but numerically less error prone, than finite-difference schemes for computing derivatives.

AN - 66897623; 15379605 AB - Mechanically sensitive ion channels (MSCs) are ubiquitous. They exist as two major types: those in specialized receptors that require fibrous proteins to transmit forces to the channel, and those in non-specialized tissues that respond to stress in the lipid bilayer. While few MSCs have been cloned, the existing structures show no sequence or structural homology--an example of convergent evolution. The physiological function of MSCs in many tissues is not known, but they probably arose from the need for cell volume regulation. Recently, a peptide called GsMTx4 was isolated from tarantula venom and is the first specific reagent for mechanosensitive channels. GsMTx4 is a approximately 4 kD peptide with a hydrophobic face opposite a positively charged face. It is active in the D and L forms, and appears non-toxic to mice. GsMTx4 has shown physiological effects on cationic MSCs in heart, smooth muscle, astrocytes, and skeletal muscle. By itself, GsMTx4 can serve as a lead compound or as a potential drug. Its availability opens clinical horizons in the diagnosis and treatment of pathologies including cardiac arrhythmia, muscular dystrophy and glioma. JF - Current drug targets.

The spring fluids have total dissolved solids (TDS) up to 7000 mg/L and Na (super +) , and K (super +) typically comprise approximately 50% of the cationic charge, indicating that high-temperature silicate alteration is the dominant source of hot spring alkalinity. HCO (sub 3) (super -) is normally the dominant anion. Sr isotope ratios from the hydrothermal fluids are similar to the range of values found in the host rocks and imply significant fluid-rock interaction with local lithologies. To determine the impact of the hydrothermal solute load on the local and regional river chemistry, we use a chemical mass balance approach to quantify the hot spring discharge. The springs are ubiquitously enriched in germanium (Ge) with high but variable Ge/Si. Himalayan rivers upstream of the hot spring zones have Ge/Si systematics like other unpolluted rivers, but downstream they are highly anomalous, with Ge/Si from 2 to 20 mu mol/mol. Ge and Si appear to behave conservatively during mixing of spring and river, and the large disparity between river and spring [Ge] and Ge/Si ratios makes germanium an effective tracer of hot spring input. We use the Ge/Si mass balance to estimate the spring flux to individual river systems. Our results show that the premonsoon spring flow over the entire Narayani basin is about 2 m (super 3) /s (with a factor of 2 uncertainty), or 0.5% of the total Narayani river discharge. We estimate that the springs provide 25 (+ or -15)% of the silicate-derived alkalinity to the Narayani system during the low-flow season from October to May. Available monsoon season data indicate that the spring flux increases during the monsoon by a factor of 2-3, but this increased flow is diluted by the up to 10X increase in overall river flow. The annual river discharge-weighted mean spring flux is 3.0+ or -1.2 m (super 3) /s for the Narayani; hydrothermal alteration contributes approximately 10% of the annual flux of silicate alkalinity to this large river system.

The method is noninvasive, fast, inexpensive and does not require complex sample preparation. It uses coal grains of about 0.8 mm size mounted in standard pellets as used for petrographic studies. Assuming spherical pore geometry, the scattering data are converted into the pore size distribution in the size range 1 nm (10 Aa) to 20 mu m (200,000 Aa) in diameter, accounting for both open and closed pores. FTIR as well as SAXS and SANS data for seven samples of oriented whole coals and corresponding pellets with vitrinite reflectance (R (sub o) ) values in the range 0.55% to 5.15% are presented and analyzed. Our results demonstrate that pellets adequately represent the average microstructure of coal samples. The scattering data have been used to calculate the maximum surface area available for methane adsorption. Total porosity as percentage of sample volume is calculated and compared with worldwide trends. By demonstrating the applicability of SAXS and SANS techniques to determine the porosity, pore size distribution and surface area in coals, we provide a new and efficient tool, which can be used for any type of coal sample, from a thin slice to a representative sample of a thick seam.

Batch experiments, in which ozone-containing gas was continuously recycled through a soil bed, were conducted to quantify the rate of ozone self-decomposition and the rates of ozone interaction with soil organic and inorganic matter. Column experiments were conducted to measure ozone breakthrough from a soil column. Parameters such as ozone flow rate, soil mass, and ozonation time were varied in these experiments. After ozone concentration had reached steady state, the total organic carbon concentration was measured for all soil samples. The ozonation efficiency, represented by the ratio of soil organic matter consumed to the total ozone input, was quantified for each experiment. Numerical simulations were conducted to simulate experimentally obtained column breakthrough curves. Experimentally obtained kinetic rate constants were used in these simulations, and the results were in good agreement with experimental data. In contrast to previous studies in which soil inorganic matter was completely ignored, our experiments indicate that soil inorganic matter may also promote depletion of ozone, thus reducing the overall ozonation efficiency. Three-dimensional numerical simulations were conducted to predict the efficacy of ozonation for soil remediation in the field. These simulations indicate that such ozonation can be very effective, provided that effective circulation of ozone is achieved through appropriately placed wells.

As a result, they are routinely detected in air and water. Methods and routes of biodegradation of these compounds are being sought. We report that under aerobic, photosynthetic conditions, the cyanobacterium Anabaena sp. transformed methyl parathion first to o, o-dimethyl o-p-nitrosophenyl thiophosphate and then to o, o-dimethyl o-p-aminophenyl thiophosphate by reducing the nitro group. The process of methyl parathion transformation occurred in the light, but not in the dark. Methyl parathion was toxic to cyanobacteria in the dark but did not affect their viability in the light. Methyl parathion transformation was not affected by mutations in the genes involved in nitrate reduction in cyanobacteria.

They also represent a key method for testing hypotheses about the response of forest ecosystems to multiple changing environmental conditions. This paper describes the evaluation of 13 stand-level models varying in their spatial, mechanistic, and temporal complexity for their ability to capture intra- and interannual components of the water and carbon cycle for an upland, oak-dominated forest of eastern Tennessee. Comparisons between model simulations and observations were conducted for hourly, daily, and annual time steps. Data for the comparisons were obtained from a wide range of methods including: eddy covariance, sapflow, chamber-based soil respiration, biometric estimates of stand-level net primary production and growth, and soil water content by time or frequency domain reflectometry. Response surfaces of carbon and water flux as a function of environmental drivers, and a variety of goodness-of-fit statistics (bias, absolute bias, and model efficiency) were used to judge model performance. A single model did not consistently perform the best at all time steps or for all variables considered. Intermodel comparisons showed good agreement for water cycle fluxes, but considerable disagreement among models for predicted carbon fluxes. The mean of all model outputs, however, was nearly always the best fit to the observations. Not surprisingly, models missing key forest components or processes, such as roots or modeled soil water content, were unable to provide accurate predictions of ecosystem responses to short-term drought phenomenon. Nevertheless, an inability to correctly capture short-term physiological processes under drought was not necessarily an indicator of poor annual water and carbon budget simulations. This is possible because droughts in the subject ecosystem were of short duration and therefore had a small cumulative impact. Models using hourly time steps and detailed mechanistic processes, and having a realistic spatial representation of the forest ecosystem provided the best predictions of observed data. Predictive ability of all models deteriorated under drought conditions, suggesting that further work is needed to evaluate and improve ecosystem model performance under unusual conditions, such as drought, that are a common focus of environmental change discussions.

In this paper, we develop Carbon Management Response (CMR) curves that could be used as an alternative to in situ measurements. The CMR curves developed here are based on quantitative reviews of existing global analyses and field observations of changes in soil carbon. The curves show mean annual rates of soil carbon change, estimated time to maximum rates of change, and estimated time to a new soil carbon steady state following the initial change in management. We illustrate how CMR curves could be used in a carbon accounting framework while effectively addressing a number of potential policy issues commonly associated with carbon accounting. We find that CMR curves provide a transparent means to account for changes in soil carbon accumulation and loss rates over time, and also provide empirical relationships that might be used in the development or validation of ecological or Earth systems models.

Penetration of DNA-modified carbon nanofibers into live cells using this platform provides efficient delivery and expression of exogenous genes, similar to "microinjection"-styled methods, but on a massively parallel basis. Spatially registered indices on the substrate allow one to conveniently locate individual cells, facilitating temporal tracking of gene expression events. We describe fabrication and use of this gene delivery platform which consists of arrays of individual carbon nanofibers at 5- mu m pitch within numerically indexed, 100- mu m square grid patterns. Fabrication of these devices on silicon substrates enables mass production of 100 devices (5 mm super(2)) per wafer, with each device providing over 800,000 nanofiber-based "needles" for cellular impalement and gene delivery applications.

AN - 85292482; pmid-15295970 AB - Ultrasonic attenuation in copper and copper-aluminum samples is measured as a function of frequency and average grain size. At low frequencies the attenuation scales quadratically with the frequency and linearly with average grain size. In addition, there is a large difference in attenuation between powder metallurgy samples and cast-and-wrought samples, although their qualitative behaviors are similar both in terms of frequency dependence and grain size dependence. Such difference and the discrepancy with the existing theory may point to mechanisms of scattering by grain boundaries that are not included in the current theoretical model.

AN - 66930284; 15085300 AB - A study was conducted to determine the diversity of 2-, 3-, and 4-chlorobenzoate (CB) degraders in two pristine soils with similar physical and chemical characteristics. Surface soils were collected from forested sites and amended with 500 microg of 2-, 3-, or 4-CB g(-1) soil. The CB levels and degrader numbers were monitored throughout the study. Degraders were isolated, grouped by DNA fingerprints, identified via 16S rDNA sequences, and screened for plasmids. The CB genes in selected degraders were isolated and/or sequenced. In the Madera soil, 2-CB and 4-CB degraded within 11 and 42 d, respectively, but 3-CB did not degrade. In contrast, 3-CB and 4-CB degraded in the Oversite soil within 14 and 28 d, respectively, while 2-CB did not degrade. Approximately 10(7) CFU g(-1) of degraders were detected in the Madera soil with 2-CB, and the Oversite soil with 3- and 4-CB. No degraders were detected in the Madera soil with 4-CB even though the 4-CB degraded. Nearly all of the 2-CB degraders isolated from the Madera soil were identified as a Burkholderia sp. containing chromosomally encoded degradative genes. In contrast, several different 3- and 4-CB degraders were isolated from the Oversite soil, and their populations changed as CB degradation progressed. Most of these 3-CB degraders were identified as Burkholderia spp. while the majority of 4-CB degraders were identified as Bradyrhizobium spp. Several of the 3-CB degraders contained the degradative genes on large plasmids, and there was variation between the plasmids in different isolates. When a fresh sample of Madera soil was amended with 50, 100, or 200 microg 3-CB g(-1), 3-CB degradation occurred, suggesting that 500 microg 3-CB g(-1) was toxic to the degraders. Also, different 3-CB degraders were isolated from the Madera soil at each of the three lower levels of 3-CB. No 2-CB degradation was detected in the Oversite soil even at lower 2-CB levels. These results indicate that the development of 2-, 3-, and 4-CB degrader populations is site-specific and that 2-, 3-, and 4-CB are degraded by different bacterial populations in pristine soils. These results also imply that the microbial ecology of two soils that develop under similar biotic and abiotic environments can be quite different.

AN - 66688622; 15240314 AB - To effectively monitor biodegrading populations, a comprehensive 50-mer-based oligonucleotide microarray was developed based on most of the 2,402 known genes and pathways involved in biodegradation and metal resistance. This array contained 1,662 unique and group-specific probes with <85% similarity to their nontarget sequences. Based on artificial probes, our results showed that under hybridization conditions of 50 degrees C and 50% formamide, the 50-mer microarray hybridization can differentiate sequences having <88% similarity. Specificity tests with representative pure cultures indicated that the designed probes on the arrays appeared to be specific to their corresponding target genes. The detection limit was approximately 5 to 10 ng of genomic DNA in the absence of background DNA and 50 to 100 ng of pure-culture genomic DNA in the presence of background DNA or 1.3 x 10(7) cells in the presence of background RNA. Strong linear relationships between the signal intensity and the target DNA and RNA were observed (r(2) = 0.95 to 0.99). Application of this type of microarray to analyze naphthalene-amended enrichment and soil microcosms demonstrated that microflora changed differently depending on the incubation conditions. While the naphthalene-degrading genes from Rhodococcus-type microorganisms were dominant in naphthalene-degrading enrichments, the genes involved in naphthalene (and polyaromatic hydrocarbon and nitrotoluene) degradation from gram-negative microorganisms, such as Ralstonia, Comamonas, and Burkholderia, were most abundant in the soil microcosms. In contrast to general conceptions, naphthalene-degrading genes from Pseudomonas were not detected, although Pseudomonas is widely known as a model microorganism for studying naphthalene degradation. The real-time PCR analysis with four representative genes showed that the microarray-based quantification was very consistent with real-time PCR (r(2) = 0.74). In addition, application of the arrays to both polyaromatic-hydrocarbon- and benzene-toluene-ethylbenzene-xylene-contaminated and uncontaminated soils indicated that the developed microarrays appeared to be useful for profiling differences in microbial community structures. Our results indicate that this technology has potential as a specific, sensitive, and quantitative tool in revealing a comprehensive picture of the compositions of biodegradation genes and the microbial community in contaminated environments, although more work is needed to improve detection sensitivity.

The oceanic sink accounts for approximately 48% of the total fossil-fuel and cement-manufacturing emissions, implying that the terrestrial biosphere was a net source of CO (sub 2) to the atmosphere of about 39+ or -28 petagrams of carbon for this period. The current fraction of total anthropogenic CO (sub 2) emissions stored in the ocean appears to be about one-third of the long-term potential.

Both of these techniques have potential use for measuring aspects of carbon content and its role in the soil ecosystem. To better understand the relationship between the microbial community and the amount of carbon within mine soils, we examined the diversity among fungal communities in soils with different carbon content using TRFLP. TRFLP was run on 18S rDNA from polymerase chain reaction (PCR) amplification using primers specific for fungi. Results from the TRFLP were compared to sequencing of 18S clones. The diversity based on sequence analysis was much higher than that indicated by the TRFLP-based analysis. Rarefaction analysis of the data indicated that the total diversity was even higher than we were able to measure with both levels of effort; however, it was clear that we effectively sampled the dominant populations. The LIBS technique displayed a strong linear relationship when compared to conventional techniques (LECO and Walkley-Black) of measuring carbon in soils. In addition, discrepancies were noted between the two conventional techniques for soils with high carbon content.

Both the quantity and the quality of soil C inputs influence C storage and the potential for C sequestration. Changes in tillage intensity and crop rotations can also affect C sequestration by changing the soil physical and biological conditions and by changing the amounts and types of organic inputs to the soil. Analyses of changes in soil C and N balances are being supplemented with studies of the management practices needed to manage soil carbon and the implications for fossil-fuel use, emission of other greenhouse gases (such as N sub(2)O and CH sub(4)), and impacts on agricultural productivity. The Consortium for Research on Enhancing Carbon Sequestration in Terrestrial Ecosystems (CSiTE) was created in 1999 to perform fundamental research that will lead to methods to enhance C sequestration as one component of a C management strategy. Research to date at one member of this consortium, Oak Ridge National Laboratory, has focused on C sequestration in soils and we begin here to draw together some of the results.

DNA adduct formation causes alteration of the DNA (RNA) sequence since neither adenine nor guanine can normally bind to its complementary nucleotide base, thymine (uracil) and cytosine respectively. The inability to form these bonds leads to mutations in the DNA double-helix structure during DNA replication, and eventually carcinogenesis. Therefore, the capability to detect and measure PAC species such as BaP in single living cells is important for studies required to establish the limits of BaP exposure necessary for carcinogenesis. Along these lines, we have developed antibody-based optical nanoprobes capable of detecting and measuring BaP in single living cells. The results obtained in this work demonstrate the practical application of antibody-based nanoprobes for performing measurements inside single living cells with their elements and their relationships intact.

We present a nearly continuous 6-year record of fine-root production and mortality from minirhizotron analysis of a closed-canopy, deciduous sweetgum forest in a free-air CO sub(2) enrichment experiment. Annual production of fine roots was more than doubled in plots with 550 ppm CO sub(2) compared with plots in ambient air. This response was the primary component of the sustained 22% increase in net primary productivity. Annual fine-root mortality matched annual production, and the mean residence time of roots was not altered by elevated CO sub(2), but peak fine-root standing crop in midsummer was significantly higher in CO sub(2)-enriched plots, especially deeper in the soil profile. The preferential allocation of additional carbon to fine roots, which have a fast turnover rate in this species, rather than to stemwood reduces the possibility of long-term enhancement by elevated CO sub(2) of carbon sequestration in biomass. However, sequestration of some of the fine-root carbon in soil pools is not precluded, and there may be other benefits to the tree from a seasonally larger and deeper fine-root system. Root-system dynamics can explain differences among ecosystems in their response to elevated atmospheric CO sub(2); hence, accurate assessments of carbon flux and storage in forests in a globally changing atmosphere must account for this unseen and difficult-to- measure component.

Agouti regulates the switch between black and yellow hair pigmentation by signalling through the melanocortin 1 receptor (Mc1r) on melanocytes. Lethal yellow (Ay) and viable yellow (Avy) are dominant regulatory mutations in the mouse agouti gene that cause the wild-type protein to be produced at abnormally high levels throughout the body. Mice harboring these mutations exhibit a pleiotropic syndrome characterized by yellow coat color, obesity, hyperglycemia, hyperinsulinemia, and increased susceptibility to hyperplasia and carcinogenesis in numerous tissues, including the liver. The goal of this research was to determine if ectopic expression of the agouti gene in the liver alone is sufficient to recapitulate any aspect of this syndrome. For this purpose, we generated lines of transgenic mice expressing high levels of agouti in the liver under the regulatory control of the albumin promoter. Expression levels of the agouti transgene in the liver were quantified by Northern blot analysis. Functional agouti protein in the liver of transgenic mice was assayed by its ability to inhibit binding of the alpha-melanocyte stimulating hormone (alphaMSH) to the Mc1r. Body weight, plasma insulin and blood glucose levels were analyzed in control and transgenic mice. Control and transgenic male mice were given a single intraperitoneal injection (10 mg/kg) of the hepatocellular carcinogen, diethylnitrosamine (DEN), at 15 days of age. Mice were euthanized at 36 or 40 weeks after DEN injection and the number of tumors per liver and total liver weights were recorded.RESULTSThe albumin-agouti transgene was expressed at high levels in the livers of mice and produced a functional agouti protein. Albumin-agouti transgenic mice had normal body weights and normal levels of blood glucose and plasma insulin, but responded to chemical initiation of the liver with an increased number of liver tumors compared to non-transgenic control mice.CONCLUSIONSThe data demonstrate that liver-specific expression of the agouti gene is not sufficient to induce obesity or diabetes, but, in the absence of these factors, agouti continues to promote hepatocellular carcinogenesis.

AN - 72026154; 15198828 AB - Perchlorate (ClO4-) has recently emerged as a widespread environmental contaminant found in groundwater and surface water, and there is a great need for rapid detection and monitoring of this contaminant. In this study, we explore the use of surface-enhanced (SERS) and normal Raman spectroscopy for detecting ClO4- at low concentrations. We found that ClO4- is SERS active and, for the first time, were able to detect ClO4- at concentrations as low as 10(-6)-10(-7) M (or 10-100 microg/L) through the application of silver SERS substrates or selective sorbents such as bifunctional anion-exchange resins. The use of selective sorbents greatly enhanced the reproducibility and sensitivity of ClO4- detection by normal Raman spectroscopy. Further exploration and research may allow application of these techniques for in situ, real-time detection and monitoring of ClO4- in environmental samples at even lower concentrations.

AN - 71971494; 15170233 AB - Purified RNA polymerase from Bacillus subtilis and other Gram-positive organisms contains a novel subunit designated delta encoded by the rpoE gene. There is no distinctive phenotype of strains with a disruption of this gene, so the function of delta is very subtle or redundant. We have found, however, that suppression of a block in sporulation of B. subtilis at early stage III owing to disruption of the pdhC gene encoding the E2 subunit of pyruvate dehydrogenase (PDH) was attributable to a Tn10 insertion in the rpoE gene. An independent disruption of this gene also caused suppression. An earlier sporulation block due to absence of the E1beta subunit of PDH was not suppressed. This specific suppression indicates that the delta subunit does have some direct or indirect role in sporulation, probably in the transcription of selected genes at stage II-III of sporulation, which is critical but only when there is functional E2.

AN - 66657412; 15224753 AB - Competitive ion-exchange reactions were studied on a strong-base anion-exchange resin to remove NO3- and uranium from a contaminated groundwater containing high levels of NO3- (approximately 140 mM), SO4(2-) (approximately 10 mM), and U(VI) (approximately 0.2 mM). Results indicate that although SO4(2-) carries divalent negative charges, it showed the least selectivity for sorption by the Purolite A-520E resin, which is functionalized with triethylamine exchange sites. Nitrate was the most strongly sorbed. Sorption selectivity followed the order of NO3- > Cl- > SO4(2-) under the experimental conditions. Nitrate competitively sorbed and displaced previously sorbed SO4(2-) in a column flow-through experiment and resulted in a high elution front of SO4(2-) in the effluent. Although the concentration of uranium in groundwater is orders of magnitude lower than that of NO3- or SO4(2-), it was found to be strongly sorbed by the anion-exchange resin. Because the most stable uranium species in oxic and suboxic environments is the UO2(2+) cation, its strong sorption by anion-exchange resins is hypothesized to be the result of the co-ion effect of NO3- by forming anionic UO2(NO3)3- complexes in the resin matrix. These observations point out a potential alternative remediation strategy that uses strong-base anion-exchange resins to remove uranium from this site-specific groundwater, which has a low pH and a relatively high NO3- concentration.

The timing of this shift in seawater chemistry broadly coincides with the "Cambrian explosion," a brief drop in marine (super 87) Sr/ (super 86) Sr values, and an increase in tectonic activity, suggesting a link between the advent of biocalcification, hydrothermal mid-ocean-ridge brine production, and the composition of seawater. The Early Cambrian surge in oceanic [Ca (super 2+) ] was likely the first such increase following the rise of metazoans and may have spurred evolutionary changes in marine biota.

The experiments were conducted on single, preannealed crystals of Chihuahuan calcite in an isotopically labeled atmosphere, and the diffusion profiles were measured by secondary ionization mass spectrometry (SIMS). At 800 degrees C, D (sub c) and D (sub o) are identical at 0.1 MPa at a value of approximately 10-13.5 cm (super 2) /s. The value of D (sub c) decreases to approximately 10-16 cm (super 2) /s with an increase in pressure to approximately 50 MPa and remains at that value to 200 MPa, but D (sub o) remains nearly constant at a value of approximately 10-14 cm (super 2) /s to 200 MPa. The identical values at low pressure indicate that C and O are migrating together as a carbonate anion. A simple model relates the diffusivity of carbonate anions to the formation of vacancies at the crystal surface, which predicts that D (sub c) varies as 1/f (sub CO2) . The prediction matches the observed decrease in D (sub c) with increasing pressure to 50 MPa. The shapes of the diffusion profiles for the low-pressure experiments indicate compositional dependence of D, which also suggests the influence of CO (sub 2) sorption on the diffusivity. The value of D (sub c) at 0.1 MPa can be fitted to the relation D (sub c) = 0.62 exp[(-291 kJ/mol)/RT]. The activation energy is nearly twice the value determined for D (sub c) at 100 MPa, approximately 166 kJ/mol. The change in slope for log D (sub c) vs. P and the change in E (sub a) between 0.1 and 100 MPa suggest that the migrating C species changes from carbonate anions at low pressure to carbon atoms at P> or =50 MPa. The values of D (sub o) at 0.1 MPa can be fitted to D (sub o) = 0.017 exp[(-261 kJ/mol)/RT], approximately the same as for C at 0.1 MPa and similar to the relation for D (sub o) at 100 MPa: D (sub o) = 0.008 exp[(-242 kJ/mol)/RT].

The corrosion crust of the pipe, soil from inside the pipe, and soil from around the pipe were characterized by chemical means and by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX). The chemical and thermal conditions necessary to produce the identified Pb mineral assemblage was investigated through the development of activity and predominance diagrams. Analysis of total soil Pb concentrations indicates that the lateral movement of Pb from the pipe in the pH >8 soil has exceeded 9 cm. However, background soil Pb concentrations are observed at a lateral distance of 50 cm. The corrosion crust of the lead pipe is composed of litharge [alpha -PbO(s)], cerussite [PbCO (sub 3) (s)], and hydrocerussite [Pb (sub 3) (CO (sub 3) ) (sub 2) (OH) (sub 2) (s)]. Similarly, soil inside the pipe and in the 0- to 1-cm zone around the pipe contains cerussite and hydrocerussite. A detailed thermochemical analysis indicates that the formation of hydrocerussite is favored, relative to cerussite, when the CO (sub 2) partial pressure is approximately atmospheric (10 (super -3.5) atm or 10 (super -4.5) MPa) or less, or when the soil temperature is approximately 25 degrees C or greater. The formation of stable lead phosphates has not occurred in these alkaline environments, even though apatite is present and thermochemical analysis predicts the formation of chloropyromorphite [Pb (sub 5) (PO (sub 4) ) (sub 3) Cl(s)]. If chloropyromorphite is removed from consideration, hydroxypyromorphite [Pb (sub 5) (PO (sub 4) ) (sub 3) OH(s)] is not predicted to form in the presence of apatite.

The US Environmental Protection Agency (USEPA) recently recommended changing the basis for expressing the ambient water quality criterion for mercury from an aqueous concentration to a measure of the methylmercury concentration in fish. This change would make the regulation of mercury in surface waters a site-specific exercise in which fish-based bioaccumulation factors (BAF; the ratio of mercury concentration in fish to the concentration of mercury in water) are used to calculate aqueous concentration limits for total mercury. These limits would then be used to allocate mercury loading among various point and nonpoint sources and guide regulatory actions. In order for this approach to succeed, it is critical that the sitespecific BAFs and methylmercury:total mercury conversion factors be independent of aqueous total mercury concentration (Hg sub(T)). We investigated this relationship by measuring aqueous methylmercury and Hg sub(T)s and mercury in fish in ecologically similar warm-water streams in the southeastern United States. Bioaccumulation factors based on Hg sub(T) in water were found to decrease with increasing Hg sub(T), primarily as a consequence of the reduction in the ratio of aqueous methylmercury to total mercury with increasing Hg sub(T). Methylmercury-based BAFs did not vary as a function of Hg sub(T). The implication of this relationship is that site-specific determination of aqueous Hg sub(T) limits at contaminated sites may use BAFs that would be underestimates of the appropriate BAFs to describe mercury bioaccumulation in the system after mercury inputs have been reduced. In such cases, regulatory limits set using site-specific BAFs might not achieve their intended purpose of reducing mercury contamination in fish to acceptable concentrations.

Forest soils contain the largest and longest lived carbon pools in terrestrial ecosystems and are therefore extremely important to the land-atmosphere exchange of carbon and future climate. Soil respiration is a sensitive integrator of many soil processes that control carbon storage in soil, and is therefore a good metric of changes to soil carbon cycling. Here, we summarize soil respiration data from four forest free-air carbon dioxide enrichment (FACE) experiments in developing and established forests that have been exposed to elevated atmospheric [CO sub(2)] (168 mu L L super(-1) average enrichment) for 2-6 years. The sites have similar experimental design and use similar methodology (closed-path infrared gas analyzers) to measure soil respiration, but differ in species composition of the respective forest communities. We found that elevated atmospheric [CO sub(2)] stimulated soil respiration at all sites, and this response persisted for up to 6 years. Young developing stands experienced greater stimulation than did more established stands, increasing 39% and 16%, respectively, averaged over all years and communities. Further, at sites that had more than one community, we found that species composition of the dominant trees was a major controller of the absolute soil CO sub(2) efflux and the degree of stimulation from CO sub(2) enrichment. Interestingly, we found that the temperature sensitivity of bulk soil respiration appeared to be unaffected by elevated atmospheric CO sub(2). These findings suggest that stage of stand development and species composition should be explicitly accounted for when extrapolating results from elevated CO sub(2) experiments or modeling forest and global carbon cycles.

When deciding whether to recommend evacuation or shelter-in-place, decision makers must weigh the interaction of numerous factors that characterize the release, the meteorological conditions, and the populations that may be affected. This article examines the components of the protective action decision process and describes steps that should be taken in a planning context to prepare for efficient decision making during an emergency.

These venting hydrocarbons fuel extensive micro- and macrofaunal cold seep communities. Of particular interest is the relationship between anaerobic methane-oxidizing archaea and sulfate-reducing bacteria. It has been suggested that sulfate-dependent anaerobic methane oxidation dominates carbon oxidation and attendant authigenic carbonate precipitation at these sites. To test this assumption, we have quantified the relative contributions of dissolved carbon dioxide (Sigma CO (sub 2) ) from a variety of sources--specifically seawater, organic matter, methane, and non-methane liquid and gaseous hydrocarbons--using the carbon isotope compositions of authigenic carbonates and a simple isotopic mass balance. Our model, and a small but representative suite of data from the Gulf, demonstrates that methane is a contributor but is not the dominant source of metabolic energy at the sites of active venting. Instead, oxidation of non-methane hydrocarbons appears to be the primary source of carbonate alkalinity. The secondary role played by methane oxidation has been independently recognized by other workers from organic biomarker relationships and from disparities observed between measured rates of sulfate reduction and methane oxidation. Despite the domination of the carbon reservoir by non-methane sources, oxygen isotope data for the authigenic carbonates bear the mark of appreciable gas hydrate dissociation. This study, rather than being an exhaustive survey of Gulf of Mexico seeps, is intended only to provide a template for the investigation of the abundant authigenic carbonate deposits distributed throughout the geologic record. As in the Gulf of Mexico, many modern and ancient cold seeps are characterized by a complex interplay of carbon sources readily preserved in the delta (super 13) C values of carbonates.

The system is able to detect ordnance as small as 60-mm rounds at 1-m sensor height. We examined several transmitter and receiver configurations. Small loop receivers gave superior signal-to-noise ratios in comparison to larger receiver loops at low heights. Base frequencies of 90 Hz and 270 Hz were less affected than other base frequencies by noise produced by proximity to the helicopter and by vibration of the support structure. For small ordnance, a two-lobed, antisymmetric transmitter loop geometry produced a modest signal-to-noise enhancement compared with a large single rectangular loop, presumably because the antisymmetric transmitter produces smaller eddy currents in the helicopter body, thereby reducing this source of noise. In most cases, differencing of vertically offset receivers did not substantially improve signal-to-noise ratios at very low sensor altitudes. Signal attenuation from transmitter to target and from target to receiver causes signals from smaller ordnance to quickly become indistinguishable from geological background variations, so that above a sensor height of about 3 m only large ordnance items (e.g., bombs and large caliber artillery rounds) were consistently detected.

A percolation model is employed to simulate the distribution of TCE within 10 x 10 x 10 m source zones with spatially heterogeneous aquifer properties following a release event. Distributed aquifer properties and DNAPL saturations are utilized to simulate coupled groundwater flow and long-term dissolved phase transport. Grid-scale dissolution rates are computed based on published bench-scale relationships. Effective field-scale mass transfer coefficients are computed from simulated TCE fluxes at the downstream source zone boundary. Heterogeneity in groundwater velocity and DNAPL distributions leads to field-scale mass transfer coefficients that are much lower than laboratory-scale values. Field-scale mass transfer coefficients are observed to vary in direct proportion to the mean groundwater velocity, in contrast to laboratory studies that indicate proportionality with velocity to a power of ~0.7. Computed field-scale mass transfer coefficients vary approximately in proportion to relative DNAPL mass raised to an empirical depletion exponent, which is 1 for more randomly oriented residual DNAPL regions. The former DNAPL geometries exhibit slow reductions in source concentration and contaminant flux with time as mass depletion proceeds. The latter DNAPL geometries exhibit significant and steady declines in source concentration and contaminant flux with time as depletion occurs.

Red maple (Acer rubrum) and sugar maple (Acer saccharum) seedlings were grown for four growing seasons in open-top chambers and exposed to ambient or elevated carbon dioxide concentration [CO sub(2)] in combination with ambient or elevated temperature. Fine-root production and mortality were monitored using minirhizotrons, and root biomass was determined from soil cores. Both elevated [CO sub(2)] and temperature significantly enhanced production and mortality of fine roots during spring and summer of 1996. At the end of the experiment in September 1997, fine root biomass was significantly lower in elevated temperature chambers, but there were no effects of elevated [CO sub(2)] or the interactions between elevated [CO sub(2)] and temperature. Deciduous trees have dynamic root systems, and their activity can be enhanced by CO sub(2) enrichment and climatic warming. Static measures of root response, such as soil core data, obscure the dynamic nature, which is critical for understanding the response of forest C cycling to global change.

The field experiment consisted of an 8-h addition of 99 atom% K super(15)NO sub(3) and a conservative solute tracer. Two super(15)N tracer addition experiments were performed on consecutive days, the first under ambient NO sub(3) super(-) concentrations (23 mu g N L super(-1)) and the second with a NO sub(3) super(-) addition of approximately 500 mu g N L super(-1). We fit first-order NO sub(3) super(-) uptake and two-box denitrification models to the longitudinal measurements of tracer super(15)N in dissolved NO sub(3) super(-), N sub(2), and N sub(2)O in stream water to determine rates. Total NO sub(3) super(-) uptake rates were 0.028 m super(-1) (0.32 mu g N m super(-2) s super(-1)) and 0.01 m super(-1) (1.6 mu g N m super(-2) s super(-1)) under ambient NO sub(3) super(-) and with NO sub(3) super(-) addition, respectively. Denitrification rates were 0.0046 m super(-1) (uncertainty range of 0.002 to 0.008 m super(-1)) and 910 super(-5) m super(-1) (uncertainty range of 3 10 super(-5) to 2110 super(-5) m super(-1)) under ambient NO sub(3) super(-) and with NO sub(3) super(-) addition, respectively. Denitrification resulted almost exclusively in N sub(2) production (>99%) and comprised about 16% ( plus or minus 10%) of total NO sub(3) super(-) uptake rate under ambient NO sub(3) super(-) concentrations and about 1% ( plus or minus 1%) of total NO sub(3) uptake rate with NO sub(3) super(-) addition. Denitrification rate expressed on a mass flux basis was about 12 mu mol m super(-2) h super(-1) under ambient NO sub(3) super(-) concentrations, a value within the range reported for other streams with low NO sub(3) super(-) concentrations.

We begin by showing that the fundamental elements of information processing in electronic and genetic systems are strikingly similar, and follow this theme through a review of efforts to create synthetic genetic circuits. In particular, we describe and review the "silicon mimetic" approach, where genetic circuits are engineered to mimic the functionality of semiconductor devices such as logic gates, latched circuits, and oscillators. This is followed with a review of the analysis, modeling, and simulation of natural and synthetic genetic circuits, which often proceed in a manner similar to that used for electronic systems. We conclude by presenting examples of naturally occurring genetic and biochemical systems that recently have been conceptualized in terms familiar to systems engineers. Our review of these newly forming fields of research demonstrates that the expertise and skills contained within electrical and computer engineering disciplines apply not only to design within biological systems, but also to the development of a deeper understanding of biological functionality. This review of these efforts points to the emergence of both engineering and basic science disciplines following parallel paths.

Ecosystem models demonstrate the importance of examining the combined effects of the gradually rising concentration of atmospheric CO sub(2) and the climatic change that attends it. Models to forecast future changes need data support to be useful, and data-model fusion has become essential in global change research. There is a wealth of information on plant responses to CO sub(2) and temperature, but there have been few ecosystem-scale experiments investigating the combined or interactive effects of CO sub(2) enrichment and warming. Factorial experiments to investigate interactions can be difficult to design, conduct, and interpret, and their results may not support predictions at the ecosystem scale - in the context of global change they will always be case studies. An alternative approach is to gain a thorough understanding of the modes of action of single factors, and rely on our understanding (as represented in models) to inform us of the probable interactions. Multifactor (CO sub(2) x temperature) experiments remain important, however, for testing concepts, demonstrating the reality of multiple-factor influences, and reminding us that surprises can be expected.

The injector consisted of a coflow reactor wherein water was introduced as a jet into liquid CO sub(2), causing vigorous mixing of the two immiscible fluids to promote the formation of CO sub(2) hydrate that is stable at ambient pressures and temperatures typical of ocean depths greater than similar to 500 m. Using flow rate ratios of water and CO sub(2) of 1:1 and 5:1, particulate composites of CO sub(2) hydrate/liquid CO sub(2)/seawater phases were produced in seawater at depths between 1100 and 1300 m. The resultant composite particles were tracked by a remotely operated vehicle system as they freely traveled in an imaging box that had no bottom or top walls. Results from the field experiments were consistent with laboratory experiments, which were conducted in a 70 L high-pressure vessel to simulate the conditions in the ocean at intermediate depths. The particle velocity and volume histories were monitored and used to calculate the conversion of CO sub(2) into hydrate and its subsequent dissolution rate after release into the ocean. The dissolution rate of the composite particles was found to be higher than that reported for pure CO sub(2) droplets. However, when the rate was corrected to correspond to pure CO sub(2), the difference was very small. Results indicate that a higher conversion of liquid CO sub(2) to CO sub(2) hydrate is needed to form negatively buoyant particles in seawater when compared to freshwater, due primarily to the increased density of the liquid phase but also due to processes involving brine rejection during hydrate formation.

The strain contained the constructed plasmid pGN2 which encoded genes for 2-CB oxidation (cbdA) and the green fluorescent protein (gfp). P. putida GN2 numbers were assessed by plating onto 2-CB minimal media and also by RTm-PCR detection of cbdA and gfp. Addition of P. putida GN2 decreased the time required to degrade 2-CB in all tested soils by more than 7 days. The RTm-PCR estimations of P. putida GN2 numbers strongly correlated with those obtained from plate count methods during active 2-CB degradation. However, after 2-CB degradation in the soils had ceased, RTm-PCR estimations of cbdA and gfp genes were generally one order of magnitude lower than those from plate counts. These results indicate the potential for RTm-PCR to rapidly determine degrader numbers in soil following bioaugmentation but also the need to exercise caution when attempting to determine cell numbers of degraders from the RTm-PCR quantification of plasmid encoded genes after substrate is depleted.
