TY - JOUR T1 - Water ordering and redox process at hematite-water interfaces AN - 886907291; 2011-073698 AB - Reactions at hematite-water interfaces affect contaminant fate and transport, partially control biogeochemical iron cycling, and fractionate iron isotopes. The ability to predict and quantify these and other important processes in nature requires a fundamental understanding of the structure of hematite-water interfaces and the reactions that occur here. The ordering of water at hematite surfaces and the structural transformations these surfaces undergo as a result of reaction with aqueous Fe(II) have been characterized. Water takes on an ordered arrangement near the hematite (012) and (110) surfaces, with the degree of ordering declining away from the surface on the length scale of approximately 1-2 nanometers. Fe(II) induces orientation-dependent structural changes to hematite surfaces that suggest growth occurs on (001) and dissolution on (110) and (012). This behavior occurs under both neutral (pH 7) and acidic (pH 3) conditions. Fe(II) presumably serves a catalytic role, transporting Fe between different surfaces through solution with electrons conducting back through the hematite structure in the reverse direction. This dynamic interfacial redox process may be responsible for the recent observations of electron transfer and isotope fractionation in Fe(II)-iron oxide systems.

Gayathri Gopalakrishnan, M. Cristina Negri, Paul L. Benda and John Quinn, Argonne National Laboratory. Phytoremediation or contaminant removal using plants has been deployed at multiple sites to remediate contaminated soil and groundwater. Research has shown that trees are low-cost, rapid and relatively simple to use monitoring systems as well as inexpensive alternatives to traditional pump-and-treat systems (Vroblesky et al. 1999, Struckhoff et al. 2005, Gopalakrishnan et al 2008). However, a better understanding of the mechanisms governing the fate and transport of chemicals in plants is required to accurately predict the performance of phytoremediation systems. Plant uptake models have been developed based on direct absorption of the chemical into the root in combination with microbial degradation, followed by contaminant translocation in the transpiration stream (xylem), sorption in the plant tissue and transpiration by the leaves or diffusion out of the tree (Trapp and McFarlane, 1995; Burken and Schnoor, 1998; Ma and Burken, 2004). These models have been developed for ideal conditions that match those in the laboratory, which are approximations of field conditions. Comparison of field data with model results has indicated that model parameters such as the diffusion coefficient obtained in the field are 2-100 times greater than laboratory results (Ma and Burken 2004, Gopalakrishnan et al. 2008). This study investigates the scale effect on model parameters such as sap flow rate and diffusion coefficient as a result of differences in plant sizes, for example between hydroponic plants in the laboratory and large trees in the field. These results are then evaluated using existing models for contaminant fate and transport in plants at a phytoremediation site at Argonne National Laboratory to determine system performance as related to contaminant remediation and hydraulic control.

Bioreduction experiments were conducted with uranyl acetate as the electron acceptor and sodium lactate as the electron donor under resting cell conditions in a 30 mM NaHCO (sub 3) buffer, and in a PIPES-buffered artificial groundwater (PBAGW). MR-1 was cultured in batch mode in a defined minimal medium with a specified air-to-medium volume ratio such that electron acceptor (O (sub 2) ) limiting conditions were reached just when cells were harvested for subsequent experiments. The rate of U(VI) bioreduction was manipulated by varying the cell density and the incubation temperature (1.0X10 (super 8) cell ml (super -1) at 20 degrees C or 2.0X10 (super 8) cell ml (super -1) at 37 degrees C) to generate U(IV) solids at "fast" and "slow" rates in the two different buffers. The presence of Ca in PBAGW buffer altered U(VI) speciation and solubility, and significantly decreased U(VI) bioreduction kinetics. High resolution transmission electron microscopy was used to measure uraninite particle size distributions produced under the four different conditions. The most common primary particle size was 2.9-3.0 nm regardless of U(VI) bioreduction rate or background electrolyte. Extended X-ray absorption fine-structure spectroscopy was also used to estimate uraninite particle size and was consistent with TEM results. The reactivity of the biogenic uraninite products with dissolved oxygen was tested, and neither U(VI) bioreduction rate nor background electrolyte had any statistical effect on oxidation rates. With MR-1, uraninite particle size was not controlled by the bioreduction rate of U(VI) or the background electrolyte. These results for MR-1, where U(VI) bioreduction rate had no discernible effect on uraninite particle size or oxidation rate, contrast with our recent research with Shewanella putrefaciens CN32, where U(VI) bioreduction rate strongly influenced both uraninite particle size and oxidation rate. These two studies with Shewanella species can be viewed as consistent if one assumes that particle size controls oxidation rates, so the similar uraninite particle sizes produced by MR-1 regardless of U(VI) bioreduction rate would result in similar oxidation rates. Factors that might explain why U(VI) bioreduction rate was an important control on uraninite particle size for CN32 but not for MR-1 are discussed.

By using ultra-small angle X-ray scattering (USAXS) before and after combustion of microaggregates at 350 degrees C, we took advantage of differences in X-ray scattering contrast among soil minerals, OM, and air to evaluate the distribution of the total- and OM-filled porosity within microaggregates (53-250mu m in diameter). Systematic changes in microaggregate structure were observed for long-term field manipulations of land use (a chronosequence of tallgrass prairie restorations) and agricultural management (conventional tillage versus no-till at two levels of nitrogen fertilization). Our results imply that OM preservation arose from the evolution of the architectural system of microaggregates during their formation and stabilization. Soils and treatments with increasing OM in microaggregates were associated with encapsulation of colloidal OM by minerals, thereby creating protected OM-filled pores at the submicron scale within the microaggregate structure. For example, in the prairie chronosequence, microaggregates from the cultivated soil had the lowest concentration of OM, but 75% of the OM that had survived cultivation was in OM-filled pores. Following restoration, the concentration of OM in microaggregates increased rapidly, but the proportion of OM in OM-filled pores declined initially and then increased over time until 90% of the OM was in OM-filled pores. OM totally encapsulated within the pore structure can create spatial and kinetic constraints on microbial access to and degradation of OM. Encapsulation of OM increases the capacity for its protection relative to sorption on mineral surfaces, and comparison of its extent among treatments suggests important feedback loops. The use of USAXS, which has not previously been applied to the study of soil aggregate structures and the distribution of OM within those structures, provided new information on the mechanisms of OM protection in soil microaggregates, and insights relevant to strategies for enhancing carbon-sequestration in soil through changes in agricultural management practices and land use.

These changes alter gaseous compositions, C and N storage capacities and microbial communities among different regions within soil aggregates. Recent advances in X-ray microtomography enable the examination of intact pore networks within soil aggregates at resolutions as small as 3 microns. We hypothesize repeated and nondestructive quantitative visualizations of aggregates and soil volumes treated with multiple D/W cycles can be used to compare and identify the most ideal intra-aggregate pore structures for maximizing soil C sequestration in natural ecosystems. Geostatistical and multifractal methods provide concise characteristics of pore spatial distributions within the aggregates and are useful for comparing these alterations among soils. We compared similar air-dried aggregates from the same soil type which were subjected to multiple wetting and drying (WD) cycles. Soil aggregate samples were scanned on the bending beam line, station 13-BM-D of the GeoSoilEnvironCARS (GSECARS) at the Advanced Photon Source (APS) of Argonne National Laboratory (ANL). Incident energy of 73 keV was used to establish image resolutions from 3.3 to 13.1 microns. Geostatistical analyses confirmed our hypothesis that repeated WD cycles dramatically alter the spatial arrangements of soil particles and associate pore geometries. Aggregates with WD pretreatments developed greater spatial correlation ranges that parallel with increased 13C sorption away from respiring microorganisms. T-RFLP electropherograms of PCR-amplified 16S rDNA microbial nucleotides demonstrated significant shifts in the abundance of unique microbial ribotypes within exterior and interior regions of macroaggregates subjected to 0 and 5 D/W cycles. Modifications of intra-aggregate pores to reduce aerobic and anaerobic greenhouse gases will be described in greater detail.

This paper presents a case study showing how the hydraulic effect was simulated and evaluated to assist in both the initial design and subsequent performance validation of a full-scale field application. An integrated remediation system incorporating large-scale plantings and in-stream wetlands was designed and engineered to mitigate and control dissolved carbon tetrachloride being discharged from groundwater to surface water in a creek at a contaminated site in Murdock, Nebraska. The hydraulic control component of the remediation system was designed by using calibrated groundwater flow and transport models. The three-dimensional MODFLOW-2000 and MT3D codes were used for model development and simulation. Modules for evapotranspiration, well pumping, and drainage were applied in MODFLOW-2000 to simulate the functions of shallow plantings, deep plantings, and the hydraulically connected wetlands, respectively. The model was well calibrated with water level and contaminant data, plus measured flows from drain tiles in the area. The simulated results identified an optimal remedial configuration of shallow and deep planting zones and in-stream wetlands. The simulated hydraulic effects suggested (1) local drawdown in the planting area, resulting in significant hydraulic containment of contaminated groundwater; (2) a reduction of 90% in seepage of carbon tetrachloride to the creek; and (3) further mitigation in the wetlands. Since system installation in 2005, extensive monitoring for performance evaluation has included surface water and groundwater chemistry; plant tissue analyses; and plant growth, water flow, and weather data--plus sap flow data collected recently. Beneficial hydraulic effects have been recorded and partly quantified even at very early growth stages. The effects will be validated as the trees grow larger and increasingly exert their influence on the system.

We developed methodologies for rainfall-runoff and groundwater recharge computations that heavily rely on observations extracted from a wide-range of global remote sensing data sets (TRMM, SSM/I, Landsat TM, AVHRR, AMSR-E) using the arid Sinai Peninsula (SP) and the Eastern Desert (ED) of Egypt as our test sites. A two-fold exercise was conducted. Temporal remote sensing data (TRMM, AVHRR and AMSR-E) were extracted from global data sets over the test sites using RESDEM, the Remote Sensing Data Extraction Model, and were then used to identify and to verify precipitation events throughout the past nine years (1998-2006). The verification process is an automated technique which first identifies the presence of clouds and then test for an increase in soil moisture and vegetation intensity difference images following a precipitation event. A SWAT model was developed and calibrated against observed runoff values from Wadi Girafi and then used to provide a continuous simulation (1998-2006) of the hydrologic variables for the major (area > or = 2000 km (super 2) ) watersheds in the SP (Watir, El-Arish, Dahab, Awag) and the ED (Qena, Hammamat, Asyuti, Tarfa, El-Quffa, El-Batur, Kharit, Hodein, Allaqi). For the investigated watersheds in the SP, average annual runoff, and average annual recharge through transmission losses were found to be: 80.5 X 10 (super 6) m (super 3) , and 87.3 X 10 (super 6) m (super 3) , respectively, whereas in the ED these values are: 17.5 X 10 (super 6) m (super 3) , and 86.1 X 10 (super 6) m (super 3) , respectively. The adopted approach is not a substitute for traditional methodologies that rely on extensive datasets from rain gauge and stream flow networks, yet could provide first order estimates for rainfall, runoff, and recharge over large sectors of the arid world lacking adequate coverage with spatial and temporal precipitation and field data.

If the concentration varies with time, the actual time of exposure affects the quantity ingested. The influence of the timing of exposure and of individual variability in the volume of water ingested on estimated impacts for a contamination event has received limited attention. We examine the significance of ingestion timing and variability in the volume of water ingested by using a number of models for ingestion timing and volume. Contaminant concentrations were obtained from simulations of an actual distribution system for cases involving contaminant injections lasting from 1 to 24 h. We find that assumptions about exposure can significantly influence estimated impacts, especially when injection durations are short and impact thresholds are high. The influence of ingestion timing and volume should be considered when assessing impacts for contamination events.

At these depots, workers must don protective clothing that increases their risk of heat-related injury. Because of the difficulty in making continuous, accurate measurements of wet bulb globe temperature outdoors, the authors have developed a model of the wet bulb globe temperature that relies only on standard meteorological data available at each storage depot for input. The model is composed of separate submodels of the natural wet bulb and globe temperatures that are based on fundamental principles of heat and mass transfer, has no site-dependent parameters, and achieves an accuracy of better than 1°C based on comparisons with wet bulb globe temperature measurements at all depots.

Thus far, economic studies of nuclear hydrogen tend to focus on the levelized cost of hydrogen without accounting for the risks and uncertainties that potential investors would face. We present a financial model based on real options theory to assess the profitability of different nuclear hydrogen production technologies in evolving electricity and hydrogen markets. The model uses Monte Carlo simulations to represent uncertainty in future hydrogen and electricity prices. It computes the expected value and the distribution of discounted profits from nuclear hydrogen production plants. Moreover, the model quantifies the value of the option to switch between hydrogen and electricity production, depending on what is more profitable to sell. We use the model to analyze the market viability of four potential nuclear hydrogen technologies and conclude that flexibility in output product is likely to add significant economic value for an investor in nuclear hydrogen. This should be taken into account in the development phase of nuclear hydrogen technologies.

AAO nanowells with an average pore diameter of 73nm and with 2, 6, and 12min anodization time were immersed in a surfactant solution and coated with an 8nm film of palladium nanoparticles. The electrical resistance change of the nanostructured sensor with hydrogen gas exposure was used as the sensing parameter. The AAO nanowells and nanostructures were characterized using atomic force microscopy (AFM), field emission scanning electron microscopy (FESEM), and contact angle measurements. Using argon as a carrier gas, hydrogen concentrations as low as 0.05vol.% (500ppm) can be detected at room temperature. Response times as fast as 1.15s were obtained for the AAO nanowell-Pd nanostructure detector which compared to current devices and nanostructures in development, is found to be considerably faster without compromising sensor response magnitude and selectivity.

AN - 69657506; 18853803 AB - Electron transfer mediators (ETMs) such as low-molecular-mass quinones (e.g., juglone and lawsone) and humic substances are believed to play a role in many redox reactions involved in contaminant transformations and the biogeochemical cycling of many redox-active elements (e.g., Fe and Mn) in aquatic and terrestrial environments. This study examines the effects of a series of compounds representing major classes of natural and synthetic organic ETMs, including low-molecular-mass quinones, humic substances, phenazines, phenoxazines, phenothiazines, and indigo derivatives, on the bioreduction of lepidocrocite (gamma-FeOOH) by the dissimilatory Fe(III)-reducing bacterium Shewanella putrefaciens CN32. Although S. putrefaciens CN32 was able to reduce lepidocrocite in the absence of exogenous ETMs, the addition of exogenous ETMs enhanced the bioreduction of lepidocrocite. In general, the rate of Fe(II) production correlated well with the reduction potentials of the ETMs. The addition of humic acids or unfractionated natural organic matter at concentrations of 10 mg organic CL(-1) resulted in, at best, a minimal enhancement of lepidocrocite bioreduction. This observation suggests that electron shuttling by humic substances is not likely to play a major role in Fe(lll) bioreduction in oligotrophic environments such as subsurface sediments with low organic C contents.

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].

Chronosequence approaches offer unique opportunities to use space-for-time substitution to quantify the recovery of ecosystem C and N stocks and estimate the potential of restoration practices for C sequestration. We studied the distribution of C and N stocks in two chronosequences that included long-term cultivated lands, 3- to 26-year-old prairie restorations, and remnant prairie on two related soil series. Results from the two chronosequences did not vary significantly and were combined. Based on modeling predictions, the recovery rates of different ecosystem components varied greatly. Overall, C stocks recovered faster than N stocks, but both C and N stocks recovered more rapidly for aboveground vegetation than for any other ecosystem component. Aboveground C and N reached 95% of remnant levels in only 13 years and 21 years, respectively, after planting to native vegetation. Belowground plant C and N recovered several decades later, while microbial biomass C, soil organic C (SOC), and total soil N recovered on a century timescale. In the cultivated fields, SOC concentrations were depleted within the surface 25 cm, coinciding with the depth of plowing, but cultivation apparently led to redistribution of soil C, increasing SOC stocks deeper in the soil profile. The restoration of prairie vegetation was effective at rebuilding soil organic matter (SOM) in the surface soil. Accrual rates were maintained at 43 g C; m super(-2); yr super(-1) and 3 g N; m super(-2); yr super(-1) in the surface 0.16 Mg/m super(2) soil mass during the first 26 years of restoration and were predicted to reach 50% of their storage potential (3500 g C/m super(2)) in the first 100 years. We conclude that restoration of tallgrass prairie vegetation can restore SOM lost through cultivation and has the potential to sequester relatively large amounts of SOC over a sustained period of time. Whether restored prairies can retain the C apparently transferred to the subsoil by cultivation practices remains to be seen.

AN - 69318005; 18617797 AB - As part of the requirement for terminating the licenses of nuclear power plants or other nuclear facilities, license termination plans or decommissioning plans are submitted by the licensee to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. Decommissioning plans generally refer to the decommissioning of nonreactor facilities, while license termination plans specifically refer to the decommissioning of nuclear reactor facilities. To provide a uniform and consistent review of dose modeling aspects of these plans and to address NRC-wide knowledge management issues, the NRC, in 2006, commissioned Argonne National Laboratory to develop a Web-based training course on reviewing radiological dose assessments for license termination. The course, which had first been developed in 2005 to target specific aspects of the review processes for license termination plans and decommissioning plans, evolved from a live classroom course into a Web-based training course in 2006. The objective of the Web-based training course is to train NRC staff members (who have various relevant job functions and are located at headquarters, regional offices, and site locations) to conduct an effective review of dose modeling in accordance with the latest NRC guidance, including NUREG-1757, Volumes 1 and 2. The exact size of the staff population who will receive the training has not yet been accurately determined but will depend on various factors such as the decommissioning activities at the NRC. This Web-based training course is designed to give NRC staff members modern, flexible access to training. To this end, the course is divided into 16 modules: 9 core modules that deal with basic topics, and 7 advanced modules that deal with complex issues or job-specific topics. The core and advanced modules are tailored to various NRC staff members with different job functions. The Web-based system uses the commercially available software Articulate, which incorporates audio, video, and animation in slide presentations and has glossary, document search, and Internet connectivity features. The training course has been implemented on an NRC system that allows staff members to register, select courses, track records, and self-administer quizzes.

While the scope of this theory is attractive, the specifics of the model remain unconvincing. After a critical assessment of the currency theory of emotion, a field model of emotion is introduced that adds expressiveness by locating emotional valence within its cognitive context, thereby creating an integrated orientation field. The result is a model which claims less in the way of motivational specificity, but is more satisfactory in modeling the dynamic interaction between cognitive and emotional orientations at both individual and social levels.

The structure was modeled and refined in space group I4/m. An accurate room-temperature structure was also obtained by using synchrotron high-resolution powder X-ray diffraction (HRPXRD) data and Rietveld structure refinement. From HRPXRD, the cell parameters are a = 12.16711(2), c = 7.575466(5) Aa, and V = 1121.461(3) Aa (super 3) ; {1-O} and {T2-O} are 1.643(1) and 1.672(1), respectively, so the T1 (Al (sub 0.25) Si (sub 0.75) ) and T2 (Al (sub 0.46) Si (sub 0.54) ) sites are partially ordered at room temperature. On heating, the {T-O} distances indicate that the T1 and T2 sites become more Si- and Al-rich, respectively, and therefore, ordering increases unusually with increasing temperature. This increase in Al-Si ordering occurs from 892 to 900 degrees C. At 900 degrees C, the T1 site becomes fully ordered with only Si atoms, while the T2 site contains Al (sub 0.51) Si (sub 0.49) and therefore, is fully disordered. On cooling, the sample does not fully revert back to the original partially ordered state. At 300 degrees C, all the cell parameters are smaller because of the increased Al-Si ordering that is quenched in.

The measured thicknesses were substantially lower than those of test plates with similar power from other reactors available in the literature. The main reason is believed to be due to the lower pH (pH 5.1-5.3) of the primary coolant water in the ATR than in the other reactors (pH 5.9-6.5) for which we have data. An empirical model for oxide film thickness predictions on aluminum alloy used as fuel cladding in the test reactors was developed as a function of irradiation time, temperature, surface heat flux, pH, and coolant flow rate. The applicable ranges of pH and coolant flow rates cover most research and test reactors.

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.

MgSiO (sub 3) -rich silicate melts were among the primary components of the magma ocean and thus played essential roles in the chemical differentiation of the early Earth. Diverse macroscopic properties of silicate melts in Earth's interior, such as density, viscosity, and crystal-melt partitioning, depend on their electronic and short-range local structures at high pressures and temperatures. Despite essential roles of silicate melts in many geophysical and geodynamic problems, little is known about their nature under the conditions of Earth's interior, including the densification mechanisms and the atomistic origins of the macroscopic properties at high pressures. Here, we have probed local electronic structures of MgSiO (sub 3) glass (as a precursor to Mg-silicate melts), using high-pressure x-ray Raman spectroscopy up to 39 GPa, in which high-pressure oxygen K-edge features suggest the formation of tricluster oxygens (oxygen coordinated with three Si frameworks; (super [3]) O) between 12 and 20 GPa. Our results indicate that the densification in MgSiO (sub 3) melt is thus likely to be accompanied with the formation of triculster, in addition to a reduction in nonbridging oxygens. The pressure-induced increase in the fraction of oxygen triclusters >20 GPa would result in enhanced density, viscosity, and crystal-melt partitioning, and reduced element diffusivity in the MgSiO (sub 3) melt toward deeper part of the Earth's lower mantle.

The paper begins by discussing the often-misunderstood nature of transparency and offers an alternative explanation as conceptualized by the authors. In addition, various subcomponents of transparency are introduced and explained. Then two simple, but useful, models are introduced in an attempt to help clarify the way in which the authors view the concept. Both models are based on analogies that draw loosely from the field of optics.

AN - 70742357; 18484336 AB - With limited exceptions, proteins that account for the amyloidoses appear to be evolutionarily unrelated. Transthyretin is classified as having an "immunoglobulin-like" fold as found in light chain variable and constant domains. Thus, these amyloidogenic proteins have significant conformational similarity. In the absence of primary structure similarity sufficient to justify an inference of an evolutionary relationship, transthyretin is considered an analog of immunoglobulin domains having accrued the immunoglobulin-like fold by some form of convergent evolution of structure. Improvements in sequence comparison tools and strategies, coupled with recent logarithmic increases in the availability of primary structure data, now make it possible to suggest that transthyretin and immunoglobulins may have a common evolutionary origin. In addition, lactadherin, the medin fragment of which accounts for the most common form of human amyloid, also appears to be evolutionarily linked to transthyretin and immunoglobulins.

To address this issue, we consider the classic newsboy problem. The principles used to manage uncertainty for that case are applied to two stylized exposure examples, one for high dose and high dose rate radiation and the other for ammonia. Both incorporate expert judgment on uncertainty quantification in the dose-response relationship. The mathematical technique of probabilistic inversion also plays a key role. We propose a coupled approach, whereby scientists quantify the dose-response uncertainty using techniques such as structured expert judgment with performance weights and probabilistic inversion, and stakeholders quantify associated loss rates.

Recent developments of third-generation synchrotron X-ray sources and X-ray-based microscopy approaches for studying microbial systems have proved their utility as complements to the very powerful approaches regularly employed by electron microscopists. In addition, in recent geomicrobiological studies, researchers have begun to take advantage of the strengths of each technique by using the superior spatial resolution of the electron microscope (relative to the X-ray microscope) and the superior elemental sensitivity of the X-ray microscope (relative to the electron microscope), along with the ability of the X-ray microscope to spatially probe the chemical speciation of elements. The benefits of integrating these two nanoprobes for investigating the same microenvironments within a geomicrobial system are far superior to those of independent studies separately employing each probe.

One of the most devastated of these natural systems is the Tigris-Euphrates watershed that over the past three decades has witnessed the construction of over 60 engineering projects that eliminated seasonal flooding, reduced natural flow and dramatically reduced the areal extent (1966: 8000 km (super 2) ; 2002: 750 km (super 2) ) of the Mesopotamian Marshes downstream. We constructed a catchment-based continuous (1964-1998) rainfall runoff model for the watershed (area: 10 (super 6) km (super 2) ) using the Soil Water Assessment Tool (SWAT) model to understand the dynamics of the natural flow system, and to investigate the impacts of reduced overall flow and the related land cover and landuse change downstream in the marshes. The model was calibrated (1964-1970) and validated (1971-1998) against stream flow gauge data. Using the calibrated model we calculated the temporal variations in the average monthly flow rate (AMFR), the average monthly peak flow rate (AMPFR), and annual flow volume (AFV) of the Tigris and Euphrates into the marshes at a location near Al-Basrah city (31 degrees N, 47.5 degrees E) throughout the modeled period. Model results indicate that the AMPFR (6301 m (super 3) /s) and average annual flow volume (AAFV: 80X10 (super 9) m (super 3) /yr) for period A (10/1/1965-09/30/1973), preceding the construction of the major dams is progressively diminished in periods B1 (10/1/1973-09/30/1989; AMPFR: 3073 m (super 3) /s; AAFV: 55X10 (super 9) m (super 3) /yr) and B2 (10/1/1989-09/30/1998; AMPFR, 2319 m (super 3) /s; AAFV: 50X10 (super 9) m (super 3) /yr) that witnessed the construction of the major dams (B1: Keban, Tabqa, Hamrin, Haditha, Mosul, Karakaya; B2: Ataturk) due to the combined effects of filling artificial lakes, evaporation and infiltration of impounded water and its utilization for irrigation purposes. To investigate the impacts of reduced flow on the areal extent of the marshes, we examined the variation in marsh size extracted from temporal satellite data (1966, 1975, 1976, 1977, 1984, 1985, 1986, 1987) acquired around the same approximate time period (July to September) of the year versus simulated AFV for the period preceding the onset (1987) of major local engineering projects (e.g., Crown of Battles River, Loyalty to the Leader Canal, Mother of Battles River) in and around the investigated marshes. Results indicate that the areal extent of the Central and Al-Hammar marshes (e.g., 1966: 7970 km (super 2) , 1977: 6680 km (super 2) , 1984: 5270 km (super 2) ) decreases with a decrease in AFV (e.g., 1966: 60.8X10 (super 9) m (super 3) , 1977: 56.9X10 (super 9) m (super 3) , 1984: 37.6X10 (super 9) m (super 3) ). Using a relationship that describes the impact of reduced AFV on the areal extent of the marshes, we evaluated the impact of additional reductions in flow that will result from the implementation of the planned engineering projects on the Tigris-Euphrates system over the next few years. Upon completion of the ongoing South Eastern Anatolia project, with projected reductions in AFV exceeding 5X10 (super 9) m (super 3) /yr, the sustainable marshes in the Central and Al-Hammar area will be reduced by at least an additional 550 km (super 2) .

However, because typical sediment chemistry is not kinetically conducive to the precipitation of these minerals, the mechanism behind their formation has remained a fundamental mystery. Here, we present evidence from high-sensitivity X-ray and electrodialysis techniques to describe a mechanism by which abundant diatom-derived polyphosphates play a critical role in the formation of calcium phosphate minerals in marine sediments.

A bulk modulus (K (sub 0) ) ranging between 255 and 261 GPa is obtained when the Au scales consistent with the Pt scale are used and the data are fit to the second order Birch-Murnaghan (BM) equation. When the third order BM equation is used, we obtain K (sub 0) =250-264 GPa and K (sub 0) (super ') =3.7-4.5, which is consistent with previous low-pressure X-ray diffraction and Brillouin measurements. Within experimental uncertainties (0.5% in volume and 6% in bulk modulus), we do not resolve differences in the EOS between Fe-bearing (up to 15%) and Fe-free Pv to 1 Mbar (2600-km depth in the mantle). This is in contrast with the much larger effect of the Fe spin transition for the EOS of ferropericlase (Fp) reported recently. This is perhaps due to much more diverse states of Fe (e.g., oxidation, coordination, and spin states) in Pv than in Fp.

Emissions of sulfur dioxide peaked in about 1996, and emissions of the carbonaceous aerosols peaked in about 1994-1995, due to a variety of economic, environmental, and social forces. These emissions are converted to their contributions to aerosol optical depth (AOD) over East Asia, using regional results from the GOCART global chemical transport model. We calculate that, on average, AOD over China rose from a value of 0.25 in 1980, peaked at a value of about 0.305 in 1995-1996, and then decreased to about 0.29 in 2000. This trend is consistent with surface shortwave irradiance measurements at 52 weather stations in China, as well as with other radiation-related trends. It may also be consistent with a rise in mean surface temperatures in China starting about the middle of the 1990s.

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.

However, the characterization of multiheme cytochromes has been significantly retarded by the numerous experimental challenges encountered by researchers who attempt to overexpress these proteins, especially if isotopic labeling is required. Here we describe a methodology for isotopic labeling of multiheme cytochromes c overexpressed in Escherichia coli, using the triheme cytochrome PpcA from Geobacter sulfurreducens as a model protein. By combining different strategies previously described and using E. coli cells containing the gene coding for PpcA and the cytochrome c maturation gene cluster, an experimental labeling methodology was developed that is based on two major aspects: (i) use of a two-step culture growth procedure, where cell growth in rich media was followed by transfer to minimal media containing super(15)N-labeled ammonium chloride, and (ii) incorporation of the heme precursor delta-aminolevulinic acid in minimal culture media. The yields of labeled protein obtained were comparable to those obtained for expression of PpcA in rich media. Proper protein folding and labeling were confirmed by UV- visible and NMR spectroscopy. To our knowledge, this is the first report of a recombinant multiheme cytochrome labeling and it represents a major breakthrough for functional and structural studies of multiheme cytochromes.

The sensor domains were isolated, purified, characterized in solution, and their crystal structures were determined. In the crystal, both sensor domains form swapped dimers and show a PAS-type fold. The swapped segment consists of two helices of about 45 residues at the N terminus with the hemes located between the two monomers. In the case of the GSU0582 sensor, the dimer contains a crystallographic 2-fold symmetry and the heme is coordinated by an axial His and a water molecule. In the case of the GSU0935 sensor, the crystals contain a non-crystallographic dimer, and surprisingly, the coordination of the heme in each monomer is different; monomer A heme has His-Met ligation and monomer B heme has His-water ligation as found in the GSU0582 sensor. The structures of these sensor domains are the first structures of PAS domains containing covalently bound heme. Optical absorption, electron paramagnetic resonance and NMR spectroscopy have revealed that the heme groups of both sensor domains are high-spin and low-spin in the oxidized and reduced forms, respectively, and that the spin-state interconversion involves a heme axial ligand replacement. Both sensor domains bind NO in their ferric and ferrous forms but bind CO only in the reduced form. The binding of both NO and CO occurs via an axial ligand exchange process, and is fully reversible. The reduction potentials of the sensor domains differ by 95 mV (-156 mV and -251 mV for sensors GSU0582 and GSU0935, respectively). The swapped dimerization of these sensor domains and redox-linked ligand switch might be related to the mechanism of signal transduction by these chemotaxis proteins.

X-ray diffraction data and Raman spectra of aluminous magnesium metasilicate post-perovskite are inconsistent with the CaIrO (sub 3) structure. Instead the observations are consistent with structures intermediate between the perovskite and the CaIrO (sub 3) structure. Ab initio calculations show that the enthalpies of the kinked structures are slightly higher than the CaIrO (sub 3) structure at 0 K. Finite temperature, minor element chemistry, kinetics of phase transformation, and actual stress regime are plausible reasons for the observed differences between the present and the previously reported post-perovskite phases.

Specular X-ray reflectivity data for orthoclase in contact with 0.01 m RbCl solution at pH 5.5 reveal a systematic increase in electron density adjacent to the mineral surface with respect to that observed in contact with de-ionized water (DIW). Quantitative analysis indicates that Rb (super +) adsorbs at a height of 0.83+ or -0.03 Aa with respect to the bulk K (super +) site with a nominal coverage of 0.72+ or -0.10 ions per surface unit mesh (55.7Aa (super 2) ). These results are consistent with an ion-exchange reaction in which Rb (super +) occupies an inner-sphere adsorption (IS) site. In contrast, X-ray reflectivity data for orthoclase in contact with 0.01 m Sr(NO (sub 3) ) (sub 2) solution at pH 5.3 reveal few significant changes with respect to DIW. Resonant anomalous X-ray reflectivity was used to probe Sr (super 2+) adsorption and to image its vertical distribution. This element-specific measurement reveals that Sr (super 2+) adsorbs with a total coverage of 0.37+ or -0.02 ions per surface unit mesh, at a substantially larger height (3.28+ or -0.05 Aa) than found for Rb (super +) , and with a relatively broad density distribution (having a root-mean-square width of 1.88+ or -0.08 Aa for a single-peak model), implying that Sr (super 2+) adsorbs primarily as a fully-hydrated outer-sphere (OS), species. Comparison to a two-height model suggests that 13+ or -5% of the adsorbed Sr (super 2+) may be present as an IS species. This partitioning implies a approximately 5 kJ/mol difference in free energy between the IS and OS Sr (super 2+) on orthoclase. Differences in the partitioning of Sr (super 2+) between IS and OS species for orthoclase (001) and muscovite (001) suggest control by the geometry of the IS adsorption site. Results for the OS distribution are compared to predictions of the Poisson-Boltzmann equation in the strong coupling regime, which predicts an intrinsically narrow vertical diffuse ion distribution; the OS distribution might thus be thought of as the diffuse ion profile in the limit of high surface charge.

In situ resonant surface X-ray scattering measurements of arsenate adsorption at pH 5 in 0.01M NaCl on corundum and hematite (012) surfaces demonstrate that arsenate surface complexation is unexpectedly bimodal, adsorbing simultaneously as inner- and outer-sphere species. In addition, this bimodal behavior is found to be independent of the total arsenate solution concentration, and thus surface coverage, over the range of 10 (super -6) to 10 (super -3) M. Alternative mechanisms to produce the observed As distributions, such as arsenate dimerization or surface precipitation of an aluminum or ferric arsenate, are inconsistent with the experimentally-determined total and As-specific density profiles. Based on the location of the outer-sphere arsenate in relation to the surfaces studied, possible binding mechanisms include electrostatic attraction, hydrogen bonding to surface oxygen functional group, and configurational stabilization by interfacial water. Although the observation of outer-sphere arsenate surface complexes on a metal oxide surface is unprecedented, it is unclear if such species were absent in previous molecular-scale studies, as it is difficult for methods commonly used to investigate the mechanisms of arsenate adsorption to conclusively identify or rule out the presence of outer-sphere species when inner-sphere species are also present.

Increasing the hydrophobicity of the RTIL cation eventually leads to nitrato complex extraction as the predominant mode of partitioning, regardless of nitrate concentration.

AN - 70397767; 18293937 AB - Photosystem I (PSI) is a large membrane protein that catalyzes light-driven electron transfer across the thylakoid membrane from plastocyanin located in the lumen to ferredoxin in the stroma. Metal analysis reveals that PSI isolated from the cyanobacterial membranes of Synechococcus leopoliensishas a near-stoichiometric 1 molar equiv of Zn (2+) per PSI monomer and two additional surface metal ion sites that favor Cu (2+) binding. Two-dimensional hyperfine sublevel correlation (HYSCORE) spectroscopy reveals coupling to the so-called remote nitrogen of a single histidine coordinated to one of the Cu (2+) centers. EPR and X-ray absorption fine structure (XAFS) studies of 2Cu-PSI complexes reveal the direct interaction of ferredoxin with the Cu (2+) centers on PSI, establishing the location of native metal sites on the ferredoxin docking side of PSI. On the basis of these spectroscopic results and previously reported site-directed mutagenesis studies, inspection of the PSI crystal structure reveals a cluster of three highly conserved residues, His(D95), Glu(D103), and Asp(C23), as a likely Cu (2+) binding site. The discovery of surface metal sites on the acceptor side of PSI provides a unique opportunity to probe the stromal region of PSI and the interactions of PSI with its reaction partner, the soluble electron carrier protein ferredoxin.

In this article we describe the examination of Li sub(1.2Ni) sub(0).2Mn sub(0.6O) sub(2) (x = 0.2 in Li[Li sub(1/3-2x/3Ni) sub(x)Mn sub(2/3-x/3]O) sub(2)) samples by X-ray diffraction (XRD), high-resolution electron microscopy (HREM), scanning transmission electron microscopy (STEM), electron diffraction, X-ray energy dispersive spectroscopy (EDS), and electron energy loss spectroscopy (EELS). The studies were conducted on freshly prepared oxides, and on oxide electrodes that were electrochemically activated by cycling twice between 4.8 and 2.0 V vs. Li[super]+/Li. Rectangular and parallelogram shaped dot arrays with a spacing of 0.43 nm observed in HREM and STEM images along the [inline image][inline image] zone axis, as well as streaks at 1/3 n [inline image][inline image] (n = integer) positions in corresponding electron diffraction patterns, indicated ordering of Li-ions in the transition-metal (TM) (0 0 0 1) layers following several stacking sequences, bounded by stacking faults, along the c-axis. Chemical analysis by EDS and EELS showed that Mn, Ni and O were present in all portions of the samples examined; no evidence of elemental segregation was observed either within the grains or at grain boundaries.

The heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to the Fe(III) oxides increased with increasing pH and was coincident with a second event of Fe2+(aq) adsorption. The reaction was almost instantaneous above pH 7. In contrast, the reduction rates of Tc(VII) by DCB-reduced phyllosilicates were not sensitive to pH or to added Fe2+(aq) that adsorbed to the clay. The reduction kinetics were orders of magnitude slower than observed for the Fe(III) oxides, and appeared to be controlled by structural Fe(II). The following affinity series for heterogeneous Tc(VII) reduction by Fe(II) was suggested by the experimental results: aqueous Fe(II) approximately adsorbed Fe(II) in phyllosilicates [ion-exchangeable and some edge-complexed Fe(II)]< structural Fe(II) in phyllosilicates< Fe(II) adsorbed on Fe(III) oxides. Tc-EXAFS spectroscopy revealed that the reduction products were virtually identical on hematite and goethite that were comprised primarily of sorbed octahedral TcO (sub 2) monomers and dimers with significant Fe(III) in the second coordination shell. The nature of heterogeneous Fe(III) resulting from the redox reaction was ambiguous as probed by Tc-EXAFS spectroscopy, although Mossbauer spectroscopy applied to an experiment with (super 56) Fe-goethite with adsorbed (super 57) Fe(II) implied that redox product Fe(III) was goethite-like. The Tc(IV) reduction product formed on the DCB-reduced phyllosilicates was different from the Fe(III) oxides, and was more similar to Tc(IV) oxyhydroxide in its second coordination shell. The heterogeneous reduction of Tc(VII) to less soluble forms by Fe(III) oxide-adsorbed Fe(II) and structural Fe(II) in phyllosilicates may be an important geochemical process that will proceed at very different rates and that will yield different surface species depending on subsurface pH and mineralogy.

Argonne National Laboratory, a PCP supporting laboratory, and Savi Technology, a Lockheed Martin Company, are collaborating in the development of the RFID system, a process that involves hardware modification (form factor, seal sensor and batteries), software development and irradiation experiments. Savannah River National Laboratory and Argonne will soon field test the active RFID system on Model 9975 drums, which are used for storage and transportation of fissile and radioactive materials. Potential benefits of the RFID system are enhanced safety and security, reduced need for manned surveillance, real time access of status and history data, and overall cost effectiveness.

The monomer consists of two separately folded domains, an amino acid kinase (AAK) domain and an N-acetyltransferase (NAT) domain connected through a 10-Aa linker. The monomers assemble into a hexameric ring that consists of a trimer of dimers with 32-point symmetry, inner and outer ring diameters of 20 and 100Aa, respectively, and a height of 110Aa sub(.) Each AAK domain interacts with the cognate domains of two adjacent monomers across two 2-fold symmetry axes and with the NAT domain from a second monomer of the adjacent dimer in the ring. The catalytic sites are located within the NAT domains. Three active site residues, Arg super(316), Arg super(425), and Ser super(427), anchor N-acetylglutamate in a position at the active site to form hydrogen bond interactions to the main chain nitrogen atoms of Cys super(356) and Leu super(314), and hydrophobic interactions to the side chains of Leu super(313) and Leu super(314). The mode of binding of acetyl-CoA and CoA is similar to other NAT family proteins. The AAK domain, although catalytically inactive, appears to bind arginine. This is the first reported crystal structure of any NAGS, and it provides insights into the catalytic function and arginine regulation of NAGS enzymes.

DESIGN: An enterprise Grid software infrastructure, called caGrid version 1.0 (caGrid 1.0), has been developed as the core Grid architecture of the NCI-sponsored cancer Biomedical Informatics Grid (caBIG super(TM)) program. It is designed to support a wide range of use cases in basic, translational, and clinical research, including 1) discovery, 2) integrated and large-scale data analysis, and 3) coordinated study. MEASUREMENTS: The caGrid is built as a Grid software infrastructure and leverages Grid computing technologies and the Web Services Resource Framework standards. It provides a set of core services, toolkits for the development and deployment of new community provided services, and application programming interfaces for building client applications. RESULTS: The caGrid 1.0 was released to the caBIG community in December 2006. It is built on open source components and caGrid source code is publicly and freely available under a liberal open source license. The core software, associated tools, and documentation can be downloaded from the following URL: https://cabig.nci.nih.gov/workspaces/Architecture/caGrid. CONCLUSIONS: While caGrid 1.0 is designed to address use cases in cancer research, the requirements associated with discovery, analysis and integration of large scale data, and coordinated studies are common in other biomedical fields. In this respect, caGrid 1.0 is the realization of a framework that can benefit the entire biomedical community.

These targets include peak and rated power efficiencies of 60% and 50%, respectively, specific power and power densities of 650 We kg[super]-1 and 650 We L[super]-1, and manufactured costs of $45 and 30 kWe[super]-1 for 80 kWe[super]-1 net systems in the 2010 and 2015 systems, respectively. In this paper, we discuss the use of fuel cell system models to examine the performance and projected manufactured costs of 2005 systems and the improvements needed to meet the 2010 and 2015 system level targets. It appears possible to meet most of the 2010 performance targets with advances such as the nano-structured thin film electrocatalysts and a modified electrolyte membrane capable of operating at up to 95 [deg]C, at least for short periods. To meet the 2015 targets, however, the fuel cell systems may need to operate without pressurization at higher temperatures of up to 120 [deg]C without the need to humidify the fuel gas and air, along with several other improvements in stack and balance-of-plant components. Our simulations provide quantitative estimates of the various performance and cost parameters of the near-term and the advanced systems that can achieve the targets set for automotive fuel cell system development.

For the diffraction measurements, intensity reflection data were collected at temperatures of 295, 110 and 20 K using time-of-flight neutron diffraction methods to further examine two reversible, order-disorder type phase transitions occurring at 273 and 155 K [Cmcm (>273 K)-->Pmcn (P2 (sub 1) cn (Pmcn phase transition is the change-over of strong hydrogen bonding from the OH group to the H (sub 2) O molecule. The lowest-wavenumber OH(H (sub 2) O) band at 2780 (super -1) at 4 K is broad and asymmetric, which is related to strong hydrogen bonding, and is characterized by cm strong anharmonicity. This band was deconvoluted into a number of combination modes consisting of an internal-H (sub 2) O and various external-H (sub 2) O vibrations.

The structure was also refined at 25 degrees C using synchrotron high-resolution powder X-ray-diffraction (HRPXRD) data that gave the pseudohexagonal unit-cell parameters a 10.60791(2), c 5.88603(1) Aa, and V 573.605(2) Aa (super 3) at room temperature. The expansion of the gaudefroyite structure is nearly isotropic and is caused mainly by an increase in the Ca1-O3 distance. The volume change from 25 degrees to 486 degrees C is 2.2(2)%. Beyond 486 degrees C, significant changes were observed in the X-ray-diffraction traces; they indicate the formation of a minor second phase that exsolved from the host gaudefroyite.

It has been used successfully for material research, biology and environmental studies, e.g. in the form of mu -X-ray fluorescence and spectromicroscopy with a spatial resolution of <100 nm. With the combination of high-resolution microscopy and spectroscopy it is possible to determine elemental composition as well as chemical speciation, and also identify trace elements to nm-resolution. Samples from soils and groundwater aquifers have been imaged to visualize the appearance of structures on the nm- and mu m-scale. The effect of changing chemical conditions in an aqueous environment on the appearance of these structures has been imaged and evaluated. Clay dispersions, microhabitats and morphological effects of biologically-induced redox changes of humic substances have been imaged tomographically, conveying a detailed three-dimensional presentation of the specimen structure. Using the spectromicroscopy potential, the distribution of organic and inorganic components, as well as different inorganic components, has been studied. Spectra were analysed for major chemical constituents and were used, for example, to assess different sulphur species in an entire soil profile.

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 analyses divide into two parts: in the first part, the latest design of the reactor core proposed by General Atomics, which takes advantage of four fuel rings, has been modeled in deep details by the Monte Carlo MCNP code and a burnup process has been simulated by the MCB code. In the second part, the TRISO coated particle performances have been investigated by the PANAMA code with the goal of verifying the design constraints proposed by General Atomics. During burnup, the refueling and shuffling schedule followed the one-pass deep burn concept, where the fuel is utilized, since fabrication for the Gas Turbine-Modular Helium Reactor, without any reprocessing until the final disposal into the geological repository. During the reactor operation, the fast fluence on all TRISO particles layers has been evaluated and the production of the key fission products monitored. During an hypothetical reactor accident scenario, the TRISO particle failure fraction has been estimated.

Previous studies have demonstrated that diamonds may be synthesized in laboratory from a supercritical COH fluid at wide range of T = 1200 degrees C 1500 degrees C, and P = 7 -10 GPa. However, mechanism and kinetics of diamond nucleation from graphite and amorphous carbon in presence of such a fluid are not well constrained. We have conducted several ultrahigh-pressure experiments in laser-heated diamond anvil cell assisted with synchrotron in-situ microX-ray measurements. With these techniques we were able to establish time during which the diamonds nucleation took place. Powdered amorphous carbon (impurity < 2 ppm) and graphite (99.9% pure) were used for starting materials as a carbon source. Oxalic acid dihydrate (COOH)2.2H2O) and glucose (C6H12O6) in amount of 3 wt% were added to the starting material as a source of fluid. The prepared samples heated by laser beam at temperature of 1400-1700 degrees C were kept at pressures 8-10 GPa for 10-50 minutes. The run products show that nanocrystals of diamond were nucleated from amorphous carbon in CO2-rich fluid environment. The fastest rate of diamond nucleation and growth (15 micron size crystals) was observed in the mixture of amorphous carbon with glucose which provides CH4-rich environment. Only nanometric diamond nuclei were observed in the run product started with graphite and glucose. We have also established that under anhydrous conditions, no diamond nucleation took place in the pure graphite, but a few nanometric size diamond crystals were observed in the amorphous carbon at T = 1700-1900 degrees C, P = 10 GPa. Our results revealed that the kinetics of diamond nucleation depend on the starting materials: diamond nucleates and grows faster from amorphous carbon than from graphite in the presence of COH fluid; in our anhydrous experiments diamond nucleates only from amorphous carbon. These results demonstrate that diamonds nucleation from anhydrous graphite is hampered because of the well-known kinetic barrier, and emphasize the promoting role of a supercritical COH fluid for graphite transformation to diamond.

AN - 70153611; 18091155 AB - Performance testing results involving the operation of a gaseous-effluent tritium sampling system are provided. A system description, including design improvements made over the course of several years of operation, is also presented. The sampling technique is based on using ethylene glycol bubblers for collecting tritiated water entrained as vapor in a nitrogen purge gas from a hot cell facility. Tritiated gas is converted to water vapor using a high temperature copper oxide bed; newly-formed water molecules are readily collected in a second set of ethylene glycol bubblers. For a single bubbler containing 20 mL of ethylene glycol, the tritium collection efficiency was determined to be 98.3%. To optimize performance and to minimize the volume of mixed waste generated, tests were performed to evaluate variations in the collection efficiency as a function of sorbent volume. For purposes of comparison the performance of water-filled bubblers was also evaluated. With two water bubblers connected in series the overall collection efficiency was quite satisfactory at 95.4%, although appreciable water losses were evident. The bed oxidation efficiency for tritiated gas was evaluated over a range of temperatures; at a catalyst bed temperature of 350 degrees C nearly all the gas was converted to water vapor. System memory effects were assessed by measuring the amount of residual contamination present in the bubblers after purging the sampling system for a week offline. Contamination problems arising from previous sampling periods were inconsequential. The overall uncertainty associated with the total quantity of tritium discharged to the environment based on the results of the performance testing was estimated to be +/-24% at the 95% confidence level.

The room temperature samples above pH 3.1 all had similar Fourier transforms of their HEXS data, which were obtained from suspended slurries or precipitates. In contrast, the hydrothermal sample precipitates showed considerable variation in their HEXS correlations at longer distances. The XRD pattern of the hydrothermal sample with a pH of 5.1 exhibited Bragg reflections indexable as soddyite. While showing no evidence of crystallinity using XRD, the hydrothermal sample at pH 6 showed similar HEXS correlations, which evolved in samples at increasing pH into correlations more consistent with sodium boltwoodite. These findings are supported by thermodynamic modeling. The structural correlations seen in the HEXS data to distances of about 4A are similar in all samples prepared at pH 4 or higher. This similarity of structure is used to propose a model for solid formation that includes a uranyl silicate building block, or synthon, which preorganizes in solution. Varying the pH changes how these synthons link into larger structures.

In recognition of its importance, the Department of Homeland Security includes public confidence as one of the principal metrics used to assess the consequences of terrorist attacks. Hence, a detailed understanding of the variations in public confidence among individuals, terrorist event types, and as a function of time is critical to developing this metric. In this exploratory study, a questionnaire was designed, tested, and administered to small groups of individuals to measure public confidence in the ability of federal, state, and local governments and their public safety agencies to prevent acts of terrorism. Data was collected from three groups before and after they watched mock television news broadcasts portraying a smallpox attack, a series of suicide bomber attacks, a refinery explosion attack, and cyber intrusions on financial institutions, resulting in identity theft. Our findings are: (a) although the aggregate confidence level is low, there are optimists and pessimists; (b) the subjects are discriminating in interpreting the nature of a terrorist attack, the time horizon, and its impact; (c) confidence recovery after a terrorist event has an incubation period; and (d) the patterns of recovery of confidence of the optimists and the pessimists are different. These findings can affect the strategy and policies to manage public confidence after a terrorist event.

The hydrogen atoms of the dimethyl ammonium cation, which hydrogen bond to oxygen atoms of the formate framework, are disordered at room temperature. X-ray powder diffraction, dielectric constant, and specific heat data show that 1 undergoes an order- disorder phase transition on cooling below similar to 156 K. We present evidence that this is a classical paraelectric to antiferroelectric phase transition that is driven by ordering of the hydrogen atoms. This sort of electrical ordering associated with order-disorder phase transition is unprecedented in hybrid frameworks and opens up an exciting new direction in rational synthetic strategies to create extended hybrid networks for applications in ferroic- related fields.

In the oxidized forms, nearly identical NRVS patterns are observed, with strong bands from Fe-S stretching modes peaking around 335 cm super(-1), and additional features observed as high as the B sub(2u) mode at 6421 cm super(-1). Both forms of Rc FdVI have also been investigated by resonance Raman (RR) spectroscopy. There is good correspondence between NRVS and Raman frequencies, but because of different selection rules, intensities vary dramatically between the two kinds of spectra. For example, the B sub(3u) mode at 6288 cm super(-1), attributed to an asymmetric combination of the two FeS sub(4) breathing modes, is often the strongest resonance Raman feature. In contrast, it is nearly invisible in the NRVS, as there is almost no Fe motion in such FeS sub(4) breathing. NRVS and RR analysis of isotope shifts with super(36)S-substituted into bridging S super(2-) ions in Rc FdVI allowed quantitation of S super(2-) motion in different normal modes. We observed the symmetric Fe-Fe stretching mode at 6190 cm super(-1) in both NRVS and RR spectra. At still lower energies, the NRVS presents a complex envelope of bending, torsion, and protein modes, with a maximum at 78 cm super(-1). The super(57)Fe partial vibrational densities of states (PVDOS) were interpreted by normal-mode analysis with optimization of Urey-Bradley force fields. Progressively more complex D sub(2h) Fe sub(2)S sub(2)S' sub(4), C sub(2h) Fe sub(2)S sub(2)(SCC) sub(4), and C sub(1) Fe sub(2)S sub(2)(Cys) sub(4) models were optimized by comparison with the experimental spectra. After modification of the CHARMM22 all-atom force field by the addition of refined Fe-S force constants, a simulation employing the complete protein structure was used to reproduce the PVDOS, with better results in the low frequency protein mode region. This process was then repeated for analysis of data on the reduced FdVI. Finally, the degree of collectivity was used to quantitate the delocalization of the dynamic properties of the redox-active Fe site. The NRVS technique demonstrates great promise for the observation and quantitative interpretation of the dynamical properties of Fe-S proteins.

For DMPC-based biomembranes, polymers whose PPO chain length is less than that of the bilayer thickness insert weakly into the membrane with the PEO blocks on the same side of the bilayer, leading to delocalization of the PEO at the membrane-water interface. This polymer architecture has been found not to alter the membrane fluidity and roughness. Conversely, polymers whose chain length is sufficient to span the lipid bilayer are tightly integrated, projecting their PEO chains into the water channels on opposing sides of the bilayer. The coiled conformational state of the PEO chains produces steric pressure on the bilayer, causing a thinning of the membrane and leading to a rigid, less-mobile bilayer than systems where the polymer is introduced as the lipid conjugate.

In this work, we purified and biochemically characterized four predicted glutaminases from Escherichia coli (YbaS and YneH) and Bacillus subtilis (YlaM and YbgJ). The proteins demonstrated strict specificity to L-glutamine and did not hydrolyze D- glutamine or L-asparagine. In each organism, one glutaminase showed higher affinity to glutamine (E. coli YbaS and B. subtilis YlaM; K sub(m) 7.3 and 7.6 mM, respectively) than the second glutaminase (E. coli YneH and B. subtilis YbgJ; K sub(m) 27.6 and 30.6 mM, respectively). The crystal structures of the E. coli YbaS and the B. subtilis YbgJ revealed the presence of a classical b-lactamase-like fold and conservation of several key catalytic residues of b-lactamases (Ser74, Lys77, Asn126, Lys268, and Ser269 in YbgJ). Alanine replacement mutagenesis demonstrated that most of the conserved residues located in the putative glutaminase catalytic site are essential for activity. The crystal structure of the YbgJ complex with the glutaminase inhibitor 6-diazo-5-oxo-L-norleucine revealed the presence of a covalent bond between the inhibitor and the hydroxyl oxygen of Ser74, providing evidence that Ser74 is the primary catalytic nucleophile and that the glutaminase reaction proceeds through formation of an enzyme- glutamyl intermediate. Growth experiments with the E. coli glutaminase deletion strains revealed that YneH is involved in the assimilation of L- glutamine as a sole source of carbon and nitrogen and suggested that both glutaminases (YbaS and YneH) also contribute to acid resistance in E. coli.

The structure of the modified material and the local environment of aluminum were investigated using X-ray diffraction, HRTEM, XPS, super(27)Al MAS NMR, and [xi]-potential measurements. The effect of the aluminum modification on interaction between the dye and photocatalyst, the interfacial electron transfer process, and thereby the degradation of dye pollutants under visible irradiation were also examined by FTIR spectra and UV-vis diffuse reflectance spectra. It was found that, rather than incorporating into the crystal lattice of TiO sub(2), the aluminum forms an overlayer of Al sub(2)O sub(3) on the surface of TiO sub(2), interfaced with Ti-O- Al bonds. It is interesting that the carboxylate-containing dyes such as Rhodamine B (RhB) adsorb preferentially on the Al sub(2)O sub(3), rather than the Ti(IV) sites on the surface of TiO sub(2). The photodegradation rate observed for RhB is nearly 5-fold faster than that obtained in the pristine TiO sub(2) system. The photodegradation of dyes on the aluminum(III)-modified photocatalyst is of great dependence on the structure and anchoring group of the dyes. Structure with carboxylate as anchoring group and amino group as electron donor is favorable for degradation. The mechanistic details are discussed on the basis of experimental results.

Over the past few years, the major challenge associated with metagenomics shifted from generating to analyzing sequences. High-throughput, low-cost next-generation sequencing has provided access to metagenomics to a wide range of researchers. Results A high-throughput pipeline has been constructed to provide high-performance computing to all researchers interested in using metagenomics. The pipeline produces automated functional assignments of sequences in the metagenome by comparing both protein and nucleotide databases. Phylogenetic and functional summaries of the metagenomes are generated, and tools for comparative metagenomics are incorporated into the standard views. User access is controlled to ensure data privacy, but the collaborative environment underpinning the service provides a framework for sharing datasets between multiple users. In the metagenomics RAST, all users retain full control of their data, and everything is available for download in a variety of formats. Conclusion The open-source metagenomics RAST service provides a new paradigm for the annotation and analysis of metagenomes. With built-in support for multiple data sources and a back end that houses abstract data types, the metagenomics RAST is stable, extensible, and freely available to all researchers. This service has removed one of the primary bottlenecks in metagenome sequence analysis - the availability of high-performance computing for annotating the data.

Mechanistic insights can be gleaned from the quantitative analysis of biomolecular signals that drive multicellular patterning during the natural processes of embryonic and adult development. This review describes three critical layers of signal processing that govern multicellular patterning: spatiotemporal presentation of extracellular cues, intracellular signaling networks that mediate crosstalk among extracellular cues, and finally, intranuclear signal integration at the level of transcriptional regulation. At every level in this hierarchy, the quantitative attributes of signals have a profound impact on patterning. We discuss how experiments and mathematical models are being used to uncover these quantitative features and their impact on multicellular phenotype.

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.

This study estimates the potential life-cycle energy and emission effects associated with using bio-butanol as a transportation fuel. It employs a well-to-wheels (WTW) analysis tool: the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model. The estimates of life-cycle energy use and greenhouse gas (GHG) emissions are based on an Aspen Plus(r) simulation for a corn-to-butanol production process, which describes grain processing, fermentation, and product separation. Bio-butanol-related WTW activities include corn farming, corn transportation, butanol production, butanol transportation, and vehicle operation. In this study, we also analyzed the bio-acetone that is coproduced with bio-butanol as an alternative to petroleum-based acetone. We then compared the results for bio-butanol with those of conventional gasoline. Our study shows that driving vehicles fueled with corn-based butanol produced by the current ABE fermentation process could result in substantial fossil energy savings (39%-56%) and avoid large percentage of the GHG emission burden, yielding a 32%-48% reduction relative to using conventional gasoline. On energy basis, a bushel of corn produces less liquid fuel from the ABE process than that from the corn ethanol dry mill process. The coproduction of a significant portion of acetone from the current ABE fermentation presents a challenge. A market analysis of acetone, as well as research and development on robust alternative technologies and processes that minimize acetone while increase the butanol yield, should be conducted.

However, the high similarity of 16S and 23S rRNA sequences of Bacillus cereus group organisms (up to 99-100%) and repeatedly failed attempts to develop molecular typing systems that would use DNA sequences to discriminate between species within this group have resulted in several suggestions to consider B. cereus and B. thuringiensis, or these two species together with B. anthracis, as one species. Recently, we divided the B. cereus group into seven subgroups, Anthracis, Cereus A and B, Thuringiensis A and B, and Mycoides A and B, based on 16S rRNA, 23S rRNA and gyrB gene sequences and identified subgroup-specific makers in each of these three genes. Here we for the first time demonstrated discrimination of these seven subgroups, including subgroup Anthracis, with a 3D gel element microarray of oligonucleotide probes targeting 16S and 23S rRNA markers. This is the first microarray enabled identification of B. anthracis and discrimination of these seven subgroups in pure cell cultures and in environmental samples using rRNA sequences. The microarray bearing perfect match/mismatch (p/mm) probe pairs was specific enough to discriminate single nucleotide polymorphisms (SNPs) and was able to identify targeted organisms in 5 min. We also demonstrated the ability of the microarray to determine subgroup affiliations for B. cereus group isolates without rRNA sequencing. Correlation of these seven subgroups with groupings based on multilocus sequence typing (MLST), fluorescent amplified fragment length polymorphism analysis (AFLP) and multilocus enzyme electrophoresis (MME) analysis of a wide spectrum of different genes, and the demonstration of subgroup-specific differences in toxin profiles, psychrotolerance, and the ability to harbor some plasmids, suggest that these seven subgroups are not based solely on neutral genomic polymorphisms, but instead reflect differences in both the genotypes and phenotypes of the B. cereus group organisms.

Choppers are cooled internally by recirculated distilled water maintained at 15 degree C. Numerous metallic components are used to fabricate the choppers and cooling system; water contacts many of these components, establishing a corrosion cell. T sub(o) chopper system corrosion products were investigated analytically. Results showed elevated concentrations of soluble and precipitated iron and copper in cooling water. A chemical-based corrosion strategy was implemented in a T sub(o) chopper system during mechanical tests not involving system irradiation. Chemical analyses showed that a chemical corrosion inhibitor stopped system corrosion for 6 months after its introduction. Corrosion cessation was beneficial, as mechanical tests were performed without interruption from precipitate wear on mechanical parts, flowmeter blockage, or a decrease in heat transfer capabilities. Aqueous chemical changes occurring in the cooling system upon inhibitor addition are discussed.

However, their distribution with red blood cells (RBCs) and leukocytes is not so well studied and understood. Our three-phase computational fluid dynamics approach including plasma, RBCs, and leukocytes was used to numerically simulate the local hemodynamics in such a flow regime. This model has tracked the wall shear stress (WSS), phase distributions, and flow patterns for each phase in a concentrated suspension shear flow of blood. Unlike other computational approaches, this approach does not require dispersion coefficients as an input. The non-Newtonian viscosity model was applied to a wide physiological range of hematocrits, including low shear rates. The migration and segregation of blood cells in disturbed flow regions were computed, and the results compared favorably with available experimental data. The predicted higher leukocyte concentration was correlated with relatively low WSS near the stenosis having a high WSS. This behavior was attributed to flow- dependent interactions of the leukocytes with RBCs in pulsatile flow. This three-phase hemodynamic analysis may have application to vulnerable plaque formation in arteries with in vivo complex flow conditions.

We present a 10-a regional trend of NO sub(x) emissions in China from 1995 to 2004 using a bottom-up methodology and compare the emission trends with the NO sub(2) column trends observed from GOME and SCIAMACHY, the two spaceborne instruments. We use a dynamic methodology to reflect the dramatic change in China's NO sub(x) emissions caused by energy growth and technology renewal. We use a scenario analysis approach to identify the possible sources of uncertainties in the current bottom-up inventory, in comparison with the satellite observation data. Our best estimates for China's NO sub(x) emissions are 10.9 Tg in 1995 and 18.6 Tg in 2004, increasing by 70% during the period considered. NO sub(x) emissions and satellite-based NO sub(2) columns show broad agreement in temporal evolution and spatial distribution. Both the emission inventory data and the satellite observations indicate a continuous and accelerating growth rate between 1996 and 2004 over east central China. However, the growth rate from the emission inventory is lower than that from the satellite observations. From 1996 to 2004, NO sub(x) emissions over the region increased by 61% according to the inventory, while a 95% increase in the NO sub(2) columns measured by satellite was observed during the same period. We found good agreement during summertime but a large discrepancy during wintertime. The consistency between the summertime trends suggests that the bias cannot be due to systematic error of activity data or emission factors. The reasons for the discrepancy cannot yet be fully identified, but possible explanations include an underestimation in seasonal emission variations, variability of meteorology, NO sub(x) injection height, and the increasing trend of sulfate aerosols.

Samples deformed in torsion under Newtonian creep display development of texture (or crystallographic preferred orientation) as documented with synchrotron X-ray diffraction measurements. Complex diffraction patterns were deconvoluted with the Rietveld method to obtain quantitative texture information. Torsion samples deformed up to shear strains of 4 and samples deformed in compression at higher stresses to total strains of 0.3 develop clear textures. Texture and shape preferred orientation (SPO) of torsion samples display a monoclinic pattern with an asymmetry inclined against the sense of shear, consistent with polycrystal plasticity simulations that assume the deformation is accomplished by dislocation glide. These results show that a material deforming in linear-viscous creep can develop a strong texture, in striking contrast to the paradigm that the presence of a texture precludes low-stress Newtonian behavior. Our observations show that the presence or absence of crystallographic preferred orientation is not sufficient to uniquely infer the dominant rheological/mechanical regime, as sometimes applied for interpretation of seismic anisotropy in the Earth.

The derived electron-density profile in BaCl (sub 2) shows two sharp peaks near the mica surface at 1.98(2) and 3.02(4)Aa corresponding to the heights of a mixture of Ba (super 2+) ions and water molecules adsorbed in ditrigonal cavities and water molecules coordinated to the Ba (super 2+) ions, respectively. This pattern indicates that most Ba (super 2+) ions are adsorbed on the mica surface as inner-sphere complexes in a partially hydrated form. The amount of Ba (super 2+) ions in the ditrigonal cavities compensates more than 90% of the layer charge of the mica surface. The electron-density profiles of the fulvic acids (FAs) adsorbed on the mica surface, in the absence of Ba (super 2+) , had overall thicknesses of 4.9-10.8 Aa and consisted of one broad taller peak near the surface (likely hydrophobic and positively-charged groups) followed by a broad humped pattern (possibly containing negatively-charged functional groups). The total interfacial electron density and thickness of the FA layer increased as the solution FA concentration increased. The sorbed peat FA which has higher ash content showed a higher average electron density than the sorbed soil FA. When the muscovite reacted with a pre-mixed BaCl (sub 2) -ESFA II solution, the positions of the two peaks nearest the surface matched those in the BaCl (sub 2) solution. However, the occupancy of the second peak decreased by about 30% implying that the hydration shell of surface-adsorbed Ba (super 2+) was partially substituted by FA. The two surface peaks were followed by a broad less electron-dense layer suggesting a sorption mechanism in which Ba (super 2+) acts dominantly as a bridging cation between the mica surface and FA. When the muscovite reacted first with FA and subsequently with BaCl (sub 2) , more Ba (super 2+) could be adsorbed on the FA-coated mica surface. The peak closest to the mica included Ba (super 2+) ions adsorbed directly on the mica in an amount similar to that in the BaCl (sub 2) solution but more broadly distributed. A second peak observed within the FA layer suggests that the FA coating provides additional sites for Ba (super 2+) sorption. The results indicate that enhanced uptake of heavy metals can occur when an organic coating already exists on a mineral surface.

A framework has been developed for life cycle management regarding type B radioactive and fissile materials packaging, drawing upon current US Department of Energy (DOE) storage standards and examples from interim storage of Pu bearing materials in model 9975 transportation packagings. Key issues highlighted during long term storage of Pu bearing materials included gas generation and stability of PuO sub(2+x); other operation safety issues highlighted for interim storage of model 9975 transportation packagings included the need to consider a facility design basis fire event and the long term behaviour of packaging components such as Celotex and elastomeric O-ring seals. The principles of aging management are described, and the key attributes and examples of effective aging management programmes are provided based on the guidance documents for license renewal of nuclear power plants. The Packaging Certification Program of DOE Environmental Management, Office of Safety Management and Operations, plans to expand its mission into packaging certification for storage and aging management, as well as application of advanced technology, such as radiofrequency identification, for life cycle management of radioactive materials packagings.

The Basin includes most of the southeastern part of the Bering Sea Outer Continental Shelf, including all of Bristol Bay. The area supports important habitat for a wide variety of species and globally significant habitat for birds and marine mammals, including a number of federally listed species. Villages and communities of the Alaska Peninsula and other areas bordering or near the Basin rely on its natural resources (especially commercial and subsistence fishing) for much of their sustenance and livelihood. The offshore area of the North Aleutian Basin is considered to have important hydrocarbon reserves, especially natural gas. JF - Report.

A molecule of SVN consists of a single chain 95 amino acids long, with an almost perfect sequence repeat that creates two very similar domains (RMS deviation 0.25 Aa for 40 pairs of C alpha atoms). The crystal structure differs significantly from a previously published NMR structure of the same protein, with the RMS deviations calculated separately for the N- and C-terminal domains of 5.3 Aa and 3.7 Aa, respectively, and a very different relationship between the two domains. In addition, the disulfide bonding pattern of the crystal structures differs from that described in the previously published mass spectrometry and NMR studies.

Powders of synthetic soddyite, (UO (sub 2) ) (sub 2) (SiO (sub 4) )(H (sub 2) O) (sub 2) , and uranophane, Ca[(UO (sub 2) )(SiO (sub 3) OH)] (sub 2) (H (sub 2) O) (sub 5) , were synthesized under mild hydrothermal conditions in the presence of Np (super 5+) . Synthesis experiments were conducted at various temperatures and pH of the initial solutions. Powders of soddyite exhibit increasing Np concentration with the synthesis temperature at a pH of 4, consistent with substitution of Np (super 5+) for U (super 6+) in the structure. In contrast, the general decrease of the Np concentration in powders of uranophane with increasing synthesis temperature is inconsistent with incorporation of Np (super 5+) into the structure of uranophane. These results further support the possibility that uranyl phases that form in a geological repository may impact Np mobility, but also demonstrate that additional studies of the impact of the crystal structure on incorporation are needed.

A fundamental understanding of these important processes requires knowledge of the structure of mineral-water interfaces. High-resolution specular X-ray reflectivity was used to determine the structure of the hematite (0 1 2)-water interface. Relaxation of the surface was observed to be minor, and water was found to order near the hematite surface. Two sites of adsorbed water are inferred to be ordered laterally, one bridging between triply coordinated functional groups and the other bridging between the singly coordinated functional groups on the surface, as steric constraints limit the possible arrangements of water molecules occurring at the observed heights above the hematite surface. Relaxations of the hematite and corundum (0 1 2) surfaces, which are isostructural, are similar and limited primarily to the top most layer of the structures. No significant changes to the interfacial stoichiometry (i.e., partial occupancy of surface species) are observed in either case. The structure of interfacial water is similar on the hematite and corundum (0 1 2) surfaces as well, although water appeared to be less well ordered on the hematite surface. This may be due to expected differences in the oxygen exchange rates from surface functional groups or the apparent better matching of the corundum oxygen lattice to the natural structural ordering in water, and suggests that the dielectric constant gradients of interfacial water may differ on the two surfaces. Similar charging behavior is expected for these surfaces as similar types of surface functional groups are exposed. Although generally similar, subtle differences in the reactivity of hematite and corundum (0 1 2) surfaces to arsenate adsorption, and possibly the adsorption of other species, may be related to the difference in ordering of interfacial water observed in this study.

The 200 Area sediments contained uranyl silicate mineralization (sodium boltwoodite) in restrictive microfractures in granitic clasts, in the vadose zone over a narrow range in depth. Well logging and column experiments indicated that tank wastes migrated deeper than observed in core samples. The 300 Area sediments included metatorbernite and uranium at low concentrations associated with detrital aluminosilicates, along with other mineral phases that could accommodate uranyl, such as uranophane and calcium carbonate. The association of contaminant uranyl with Hanford formation sediments provided a persistent source of uranium to groundwater. The results of both studies suggest that the formation of secondary solid uranyl-bearing phases influences the subsequent release of uranium to the environment and that our understanding of these processes and individual waste sites is incomplete.

We sought small organic molecules for lead candidate CYP51 inhibitors. The changes in CYP51 spectral properties following ligand binding make CYP51 a convenient target for high-throughput screening technologies. These changes are characteristic of either substrate binding (type I) or inhibitor binding (type II) in the active site. We screened a library of 20,000 organic molecules against Mycobacterium tuberculosis CYP51 (CYP51 sub(Mt)), examined the top type I and type II binding hits for their inhibitory effects on M. tuberculosis in broth culture, and analyzed them spectrally for their ability to discriminate between CYP51 sub(Mt) and two reference M. tuberculosis CYP proteins, CYP130 and CYP125. We determined the binding mode for one of the top type II hits, alpha -ethyl-N-4-pyridinyl-benzeneacetamide (EPBA), by solving the X-ray structure of the CYP51 sub(Mt)-EPBA complex to a resolution of 1.53 Aa. EPBA binds coordinately to the heme iron in the CYP51 sub(Mt) active site through a lone pair of nitrogen electrons and also through hydrogen bonds with residues H259 and Y76, which are invariable in the CYP51 family, and hydrophobic interactions in a phylum- and/or substrate-specific cavity of CYP51. We also identified a second compound with structural and binding properties similar to those of EPBA, 2-(benzo[d]-2,1,3-thiadiazole-4-sulfonyl)-2-amino-2-phenyl-N-(pyri d inyl-4)-acetamide (BSPPA). The congruence between the geometries of EPBA and BSPPA and the CYP51 binding site singles out EPBA and BSPPA as lead candidate CYP51 inhibitors with optimization potential for efficient discrimination between host and pathogen enzymes.

F. tularensis replicates within several cell types, eventually causing cell death by inducing apoptosis. In this study, a modified Himar1 transposon (HimarFT) was used to mutagenize F. tularensis LVS. Approximately 7,000 Km super(r) clones were screened using J774A.1 macrophages for reduction in cytopathogenicity based on retention of the cell monolayer. A total of 441 candidates with significant host cell retention compared to the parent were identified following screening in a high-throughput format. Retesting at a defined multiplicity of infection followed by in vitro growth analyses resulted in identification of approximately 70 candidates representing 26 unique loci involved in macrophage replication and/or cytotoxicity. Mutants carrying insertions in seven hypothetical genes were screened in a mouse model of infection, and all strains tested appeared to be attenuated, which validated the initial in vitro results obtained with cultured macrophages. Complementation and reverse transcription-PCR experiments suggested that the expression of genes adjacent to the HimarFT insertion may be affected depending on the orientation of the constitutive groEL promoter region used to ensure transcription of the selective marker in the transposon. A hypothetical gene, FTL_0706, postulated to be important for lipopolysaccharide biosynthesis, was confirmed to be a gene involved in O-antigen expression in F. tularensis LVS and Schu S4. These and other studies demonstrate that therapeutic targets, vaccine candidates, or virulence-related genes may be discovered utilizing classical genetic approaches in FRANCISELLA: JF - Infection and Immunity AU - Maier, Tamara M AU - Casey, Monika S AU - Becker, Rachel H AU - Dorsey, Caleb W AU - Glass, Elizabeth M AU - Maltsev, Natalia AU - Zahrt, Thomas C AU - Frank, Dara W AD - Department of Microbiology and Molecular Genetics, Medical College of Wisconsin, 8701 Watertown Plank Road, Milwaukee, Wisconsin 53226.

We present Chisel, a computational framework and a pipeline for an automated, high-resolution analysis of evolutionary variations of enzymes. Chisel allows automatic as well as interactive identification, and characterization of enzymatic sequences. Such knowledge can be utilized for comparative genomics, microbial diagnostics, metabolic engineering, drug design and analysis of metagenomes. RESULTS: Chisel is a comprehensive resource that contains 8575 clusters and subsequent computational models specific for 939 distinct enzymatic functions and, when data is sufficient, their taxonomic variations. Application of Chisel to identification of enzymatic sequences in newly sequenced genomes, analysis of organism-specific metabolic networks, 'binning' of metagenomes and other biological problems are presented. We also provide a thorough analysis of Chisel performance with other similar resources and manual annotations on Shewanella oneidensis MR1 genome. AVAILABILITY: Chisel is available for interactive use at http://compbio.mcs.anl.gov/CHISEL. The website also provides a user manual, clusters and function-specific computational models.

Although a specific biological function of the gene product is unknown, the ArsH protein was annotated as a member of the NADPH-dependent FMN reductase family based on a conserved (T/S)XRXXSX(T/S) fingerprint motif common for FMN binding proteins. Presented here are the first crystal structure of an ArsH protein from Shigella flexneri refined at 1.7 Aa resolution and results of enzymatic activity assays that revealed a strong NADPH-dependent FMN reductase and low azoreductase activities. The ArsH apo protein has an alpha / beta / alpha -fold typical for FMN binding proteins. The asymmetric unit consists of four monomers, which form a tetramer. Buried surface analysis suggests that this tetramer is likely to be the relevant biological assembly. Dynamic light scattering experiments are consistent with this hypothesis and show that ArsH in solution at room temperature does exist predominantly in the tetrameric form.

We hypothesized that relatively slow rates of U(VI) bioreduction would yield larger UO (sub 2) precipitates that would be more resistant to oxidation than those produced by rapid U(VI) bioreduction. We manipulated U(VI) bioreduction rates by varying the density of Shewanella putrefaciens CN32 added to U(VI) containing solutions with lactate as an electron donor. Characterization of biogenic UO (sub 2) particles by extended X-ray absorption fine-structure spectroscopy and transmission electron microscopy revealed that UO (sub 2) nanoparticles formed by relatively slow rates of U(VI) reduction were larger and more highly aggregated than those formed by relatively rapid U(VI) reduction. UO (sub 2) particles formed at various rates were incubated under a variety of abiotically and biologically oxidizing conditions. In all cases, UO (sub 2) that was formed by relatively slow U(VI) reduction was oxidized at a slower rate and to a lesser extent than UO (sub 2) formed by relatively rapid U(VI) bioreduction, suggesting that the stability of UO (sub 2) in situ may be enhanced by stimulation of relatively slow rates of U(VI) reduction.

While regional studies are useful in depicting broad stratigraphic relationships, they are not designed for assessing groundwater flow at more focused scales. Geostatistical methods provide a means of quantifying the vertical and lateral correlation of subsurface units. This study considers the application of two techniques: binary indicators for permeable vs. impermeable categorization, and transition probability geostatistics for handling a larger set of material types. The analysis is focused on a 4.5-county portion of central Minnesota. During Late Wisconsinan glaciation, the region was invaded by five ice lobes of different provenance. Maps of glacial landform/sediment assemblages are available from the Minnesota Department of Natural Resources and additional maps of glacial sediments and stratigraphy have been compiled by the Minnesota Geological Survey. The study area contains over 11,000 logged wells, mostly consisting of water well data. Geostatistical analysis was carried out on well logs grouped according to the specific glacial landform/sediment assemblages. The results identified the relative differences in vertical and lateral correlation among the various geomorphological units. In addition, high-quality rotasonic logs from several locations provide a point of comparison to detailed site-specific correlation relationships. The results of this study may guide data collection strategies for regional or local studies, assess uncertainty, and support a stochastic approach to groundwater flow modeling in glaciated terrain.

An integrated approach from Egypt and Saudi Arabia AN - 50462260; 2009-073406 AB - Water shortages in the Middle East are affecting human welfare and economic activity. The strong and growing demand for water in the region justifies concentrated efforts for identification and assessment of hydrologic settings favorable for groundwater entrapment and utilization that could potentially reduce these water shortages. We report two such settings currently overlooked: (1) highly fractured basement aquifers within the Najd Shear System (NSS), the largest (length: 1600 km; width: 200 km) recognized pre-Mesozoic (530-550 Ma) transcurrent fault system (Egypt and Arabia), and (2) areas of regional natural discharge in the Eastern Desert (ED), Egypt and in the Empty Quarter (EQ), Saudi Arabia. Spatial analysis of remote sensing, geologic, hydrologic, and geochemical data sets revealed a causal association between locations of productive wells and distribution of NSS structural elements. Specifically at: (1) intersection of Najd shear zones and fault systems, (2) intersections of two or more fault systems, (3) intersections of Najd-related dykes with main valleys, and (4) within tectonic melange. Locations with similar settings should be targeted for groundwater exploration. Using isotopic, geochemical, field, and remote sensing data we show: (1) aquifers cropping out at the foothills of the Red Sea mountains were recharged by precipitation over high-elevation mountainous areas, and/or by precipitation during moist climate intervals of the late Pleistocene, (2) regional groundwater flow (ED: E to W; EQ: W to E) discharges via deep-seated fault systems defining the River Nile and Gulf of Suez Complex (Egypt) and in extensive inland sabkhas in SE Arabia. Using calibrated groundwater flow models for discharge areas (Wadi Asyuti) along the River Nile and assuming similar geologic settings and discharge rates around the River Nile and the Gulf of Suez, an estimated 70 X 10 (super 7) m (super 3) /yr of groundwater may be available for sustainable development. Utilization of groundwater discharged in Arabian sabkhas is hindered by excessive salinization (TDS up to 92,000 mg/L) due to dissolution of salts from sabkhas and/or salt diapirs and concentrated by significant evaporation (delta H values ranging from -34ppm to +19ppm). Instead, efforts should concentrate on harvesting groundwater in areas west of the sabkhas/salt diapirs.

The transformation involves conversion of surface Fe(III) to Fe(II) by electron transfer from adsorbed reductant molecules followed by Fe(II) solubilization and precipitation of new phases. In the absence of direct scrutiny, single site models of this dissolution process have prevailed. Some Fe(III)-oxides such as hematite are semiconductors with a propensity for fast charge redistribution and limited electron diffusion by solid-state electron transport. Microscopic evidence suggests that sites of Fe(II) release are coupled to a process of mobile charge segregation through the surface to specific crystallographic regions. At room temperature charge carrier mobility depends on the diffusion of small polarons occurring by Fe(II/III) valence interchange. Molecular dynamics simulations and ab initio calculations predict high rates of small polaron hopping in the hematite bulk and at (001) and (012) surfaces in vacuum and in equilibrium with an overlying bulk water phase. The collective results suggest surface-specific Fe(II/III) valence cycling via oxidative Fe(II) adsorption and solid-state electron migration as a mechanism for oxide transformation. X-ray reflectivity measurements of Fe(II) interaction with hematite (001) show growth of an Fe(III) surface phase, confirming this view. The emerging picture for iron oxide transformation is one of multiple aproximal site communication by electron transport. This model has important implications for our understanding of chemical behavior at oxide-water interfaces, and therefore also the chemistry of soils and sediments.

Such processes affect contaminant fate and transport, biogeochemical element cycling, ore deposit formation, biomineralization, and nuclear waste disposal. The ability to predict and quantify these and other important processes in nature requires a fundamental understanding of the structure of mineral-water interfaces and the reactions that occur here. I will present highlights from my recent experimental work that show that the accepted model of how arsenate adsorbs to minerals may be incorrect and that reveal the dynamic behavior of an iron oxide mineral surface that may occur during biogeochemical iron cycling. I will conclude with a list of my predictions, some realistic and some far-fetched, of the discoveries we may make in the next 50 years concerning interfacial adsorption and redox reactions, and the effect these discoveries may have on how humans interact with the environment.

A fundamental understanding of these reactions, however, ultimately rests on our ability to visualize such interfaces before, during and after reactions in complex environments through in-situ measurements with Aa-scale resolution so that elementary processes can be resolved. Recent advances in imaging interfacial processes with various extensions of high resolution X-ray scattering will be described, specifically those that illustrate elemental/chemical sensitivities, lateral spatial resolution, and temporal resolution. Examples include: 1) imaging adsorbate distributions above an interface; 2) imaging sub-nanometer high interfacial topography with X-ray microscopy; and 3) observing interfacial reactions in real-time at elevated temperature and extreme pH. We will discuss the possible future impact of these capabilities to understand increasingly complex phenomena at ever more realistic conditions.

In this study we examined the potential for the uptake and reduction of U(VI) in the presence of biogenic green rust, (BioGR) biogenic magnetite (BioMAG), and biogenic siderite (BioSID) resulting from the reduction of Fe(III) oxides by Shewanella putrefaciens CN32. Suspensions of biogenic Fe(II) phases were pasteurized (70 ° C for 1 h) to eliminate the potential for microbial reduction of U(VI) and washed repeatedly to remove any soluble reductants. The suspensions were then spiked with uranyl chloride solution. Within 48 h, the total solution-phase U(VI) concentrations decreased from 500 μ M to 1.5 μ M in the U-BioGR system, to 392 μ M in the U-BioMAG system, and to 472 μ M in the U-BioSID system, as determined by ICP- OES. Analysis of the samples by U L sub(III) extended X-ray absorption fine structure spectroscopy (EXAFS) indicated that despite a stoichiometric excess of Fe(II), no more than 6% of U(VI) was reduced in the U- BioSID system, and no more than 22% of U(VI) was reduced in the U-BioMAG system. For comparison, in the U-BioGR system, no less than 80% of U(VI) was reduced to U(IV). Uptake of U(VI) by BioGR and BioMAG was accompanied by the formation of nanoparticulate uraninite. The U EXAFS data from the U-BioSID system was consistent with partial U(VI)/U(IV) substitution for Fe(II) in the surface layer of siderite particles and adsorption of U(IV). Our results clearly demonstrate that there are significant differences in reactivity among biogenic Fe(II) phases with respect to the uptake and reduction of U(VI).

Wide-angle x-ray scattering (WAXS) can be easily carried out on proteins and small molecules in solution in the absence of chemical tags or derivatives. The authors demonstrate that WAXS is a sensitive probe of ligand binding to proteins in solution and can distinguish between nonfunctional and productive binding. Furthermore, similar ligand-binding modes translate into similar scattering patterns. This approach has high potential as a novel, generic, low-throughput assay for functional ligand binding.

The HMW1 and HMW2 adhesins are major virulence factors in nontypeable Haemophilus influenzae and are prototype two-partner secretion pathway exoproteins. A key step in the delivery of HMW1 and HMW2 to the bacterial surface involves targeting to the HMW1B and HMW2B outer membrane translocators by an N-terminal region called the secretion domain. Here we present the crystal structure at 1.92Aa of the HMW1 pro-piece (HMW1-PP), a region that contains the HMW1 secretion domain and is cleaved and released during HMW1 secretion. Structural analysis of HMW1-PP revealed a right-handed beta -helix fold containing 12 complete parallel coils and one large extra-helical domain. Comparison of HMW1-PP and the Bordetella pertussis FHA secretion domain (Fha30) reveals limited amino acid homology but shared structural features, suggesting that diverse TpsA proteins have a common structural domain required for targeting to cognate TpsB proteins. Further comparison of HMW1-PP and Fha30 structures may provide insights into the keen specificity of TpsA-TpsB interactions.

Ehp was identified through a genomic scan as an uncharacterized secreted protein from S. aureus, and immunoblotting of conditioned S. aureus culture medium revealed that the Ehp protein was secreted at the highest levels during log-phase bacterial growth. The mature Ehp polypeptide is composed of 80 residues and is 44% identical to the complement inhibitory domain of S. aureus Efb (extracellular fibrinogen-binding protein). We observed preferential binding by Ehp to native and hydrolyzed C3 relative to fully active C3b and found that Ehp formed a subnanomolar affinity complex with these various forms of C3 by binding to its thioester-containing C3d domain. Site-directed mutagenesis demonstrated that Arg super(75) and Asn super(82) are important in forming the Ehp.C3d complex, but loss of these side chains did not completely disrupt Ehp/C3d binding. This suggested the presence of a second C3d-binding site in Ehp, which was mapped to the proximity of Ehp Asn super(63). Further molecular level details of the Ehp/C3d interaction were revealed by solving the 2.7-Aa crystal structure of an Ehp.C3d complex in which the low affinity site had been mutationally inactivated. Ehp potently inhibited C3b deposition onto sensitized surfaces by the alternative complement activation pathway. This inhibition was directly related to Ehp/C3d binding and was more potent than that seen for Efb-C. An altered conformation in Ehp-bound C3 was detected by monoclonal antibody C3-9, which is specific for a neoantigen exposed in activated forms of C3. Our results suggest that increased inhibitory potency of Ehp relative to Efb-C is derived from the second C3-binding site in this new protein.

Changes in regional temperature and precipitation patterns may have significant implications on our existing and future power system infrastructure. In this paper, we use results from regional climate models to examine the impacts of projected changes in temperature and precipitation on the development and operations of the power system in the Western United States. We study three scenarios to evaluate potential effects of climate change on the electricity demand as well as on the power supply side. Impacts are measured in terms of changes in investment requirements, fuel and generation mix, emissions of greenhouse gases and criteria pollutants, and thermal power water withdrawals and consumption. We also identify potential issues regarding the western transmission grid. Our methodology includes a long-term investment algorithm that takes into account interdependencies between hydroelectric, thermal power, and non-dispatchable resources, such as wind turbines. We also include temporal aspects associated with hydropower energy constraints, wind variability, thermal power plant availability, and hourly load profiles. Thermal power plant availability and resulting generation and fuel consumption are based on maintenance outage schedules and a probabilistic dispatch algorithm that accounts for random forced outages. We conclude with some observations regarding the vulnerability of our electricity infrastructure to projected regional climate changes.

This study examines the effects of a series of compounds representing major classes of natural and synthetic organic ETMs (including low molecular-mass quinones, humic substances, phenazines, phenoxazines, phenothiazines, and indigo derivatives) on the bioreduction of lepidocrocite (γ -FeOOH) by the dissimilatory Fe(III)-reducing bacterium Shewanella putrefaciens CN32. S. putrefaciens CN32 was able to reduce lepidocrocite in the absence of exogenous ETMs; however, relative to the control, all of the synthetic ETMs examined in this study enhanced the bioreduction of lepidocrocite. The extent of the enhanced bioreduction increased with decreasing reduction potential of the given ETM redox couple. However, the addition of Suwannee River fulvic acid, humic acid, or unfractionated NOM (10 mg organic C L super(-1)) resulted in, at best, a minimal enhancement of lepidocrocite bioreduction relative to the control that did not contain any added exdogenous ETM. These results suggest that the relative contribution of humic substances to microbially mediated Fe(III) reduction may be minimal in low-carbon environments such as oligotrophic lakes and typical groundwaters.

Contributions to soil respiration come both from free-living soil microorganisms decomposing soil organic matter (heterotrophic respiration) and from roots and rhizosphere microorganisms (autotrophic respiration). Little is known about the factors underlying the partitioning of soil respiration into auto- and heterotrophic components, although increasing evidence shows that these components respond differently to vegetation, climate and environmental factors. We investigated biotic and abiotic factors that affect auto- and heterotrophic respiration in a 19-year-old restored tall grass prairie at Fermi National Accelerator Laboratory in Batavia, IL. Four automated soil respiration chambers continuously measured soil CO sub(2) efflux during the growing season. Total soil respiration was separated into its hetero- and autotrophic components by using a stable- isotope mass balance technique based on the differential super(13)C/ super(12)C ratio of the respired CO sub(2) from roots and soil at the site. Keeling plot measurements and root and soil incubations were conducted every three weeks at midday and at night to detect temporal changes in the end members that affect mass balance calculations during the growing season. Continuous measurements were also made of soil moisture, soil temperature, and net ecosystem exchange derived from eddy correlation techniques. Preliminary results show that regardless of diurnal variation, the proportion of autotrophic respiration to total respiration was larger during the earlier part of the growing season while the proportion of nighttime heterotrophic respiration to total respiration increased later in the growing season. Our results suggest that differential controlling factors for soil respiration components might be operating differently in time.

Coenzyme F sub(4) sub(2) sub(0)-2 biosynthesis from 7,8-didemethyl-8-hydroxy-5-deazariboflavin (Fo) and lactaldehyde involves six enzymatic steps and five proteins (CofA, CofB, CofC, CofD, and CofE). CofE, a F sub(4) sub(2) sub(0)-0: gamma -glutamyl ligase, is responsible for the last two enzymatic steps; it catalyses the GTP-dependent addition of two L-glutamate residues to F sub(4) sub(2) sub(0)-0 to form F sub(4) sub(2) sub(0)-2. CofE is found in archaea, the aerobic actinomycetes, and cyanobacteria. Here, we report the first crystal structure of the apo-F sub(4) sub(2) sub(0)-0: gamma -glutamyl ligase (CofE-AF) from Archaeoglobus fulgidus and its complex with GDP at 2.5 A and 1.35 A resolution, respectively. The structure of CofE-AF reveals a novel protein fold with an intertwined, butterfly-like dimer formed by two-domain monomers. GDP and Mn super(2) super(+) are bound within the putative active site in a large groove at the dimer interface. We show that the enzyme adds a glutamate residue to both F sub(4) sub(2) sub(0)-0 and F sub(4) sub(2) sub(0)-1 in two distinct steps. CofE represents the first member of a new structural family of non-ribosomal peptide synthases. phosphodiester of 7,8-didemethyl-8-hydroxy-5-deazariboflavin JF - Journal of Molecular Biology AU - Nocek, B AU - Evdokimova, E AU - Proudfoot, M AU - Kudritska, M AU - Grochowski, L L AU - White, R H AU - Savchenko, A AU - Yakunin, A F AU - Edwards, A AU - Joachimiak, A AD - Biosciences, Argonne National Laboratory, 9700 South Cass Avenue, Building 202, Argonne, IL 60439, USA, andrzejj@anl.gov Y1 - 2007/09/14/ PY - 2007 DA - 2007 Sep 14 SP - 456 EP - 469 PB - Elsevier Science, P.O.

2011-092979 AB - Recent studies have suggested that Paleozoic hyperoxia enabled animal gigantism, and the subsequent hypoxia drove a reduction in animal size. This evolutionary hypothesis depends on the argument that gas exchange in many invertebrates and skin-breathing vertebrates becomes compromised at large sizes because of distance effects on diffusion. In contrast to vertebrates, which use respiratory and circulatory systems in series, gas exchange in insects is almost exclusively determined by the tracheal system, providing a particularly suitable model to investigate possible limitations of oxygen delivery on size. In this study, we used synchrotron x-ray phase-contrast imaging to visualize the tracheal system and quantify its dimensions in four species of darkling beetles varying in mass by 3 orders of magnitude. We document that, in striking contrast to the pattern observed in vertebrates, larger insects devote a greater fraction of their body to the respiratory system, as tracheal volume scaled with mass (super 1.29) . The trend is greatest in the legs; the cross-sectional area of the trachea penetrating the leg orifice scaled with mass (super 1.02) , whereas the cross-sectional area of the leg orifice scaled with mass (super 0.77) . These trends suggest the space available for tracheae within the leg may ultimately limit the maximum size of extant beetles. Because the size of the tracheal system can be reduced when oxygen supply is increased, hyperoxia, as occurred during late Carboniferous and early Permian, may have facilitated the evolution of giant insects by allowing limbs to reach larger sizes before the tracheal system became limited by spatial constraints.

These features represent a challenge for computational science. We discuss how a leading software framework for advanced scientific computing (the Portable Extensible Toolkit for Scientific Computation, PETSc) can facilitate the development of geodynamics simulations. To illustrate our use of PETSc, we describe simulations of (i) steady-state, non-Newtonian passive flow and thermal structure beneath a mid-ocean ridge, (ii) magmatic solitary waves in the mantle, and (iii) the formation of localized bands of high porosity in a two-phase medium being deformed under simple shear. We highlight two supplementary features of PETSc, structured storage of application parameters and self-documenting output, that are especially useful for geodynamics simulations.

While most heavy element compositions were consistent with model predictions for the slow neutron capture process (s-process) in low-mass (1.5-3 M) asymptotic giant branch stars of solar metallicity when viewed on single-element three-isotope plots, grains with compositions deviating from model predictions were identified on multi-element plots. These grains have compositions that cannot result from any neutron capture process but can be explained by contamination in some elements with solar system material. Previous work in which only one heavy element per grain was examined has been unable to identify contaminated grains. The multi-element analyses of this study detected contaminated grains which were subsequently eliminated from consideration. The uncontaminated grains form a data set with a greatly reduced spread on the three-isotope plots of each element measured, corresponding to a smaller range of (super 13) C pocket efficiencies in parent AGB stars. Furthermore, due to this reduced spread, the nature of the stellar starting material, previously interpreted as having solar isotopic composition, is uncertain. The constraint on (super 13) C pocket efficiencies in parent stars of these grains may help uncover the mechanism responsible for formation of (super 13) C, the primary neutron source for s-process nucleosynthesis in low-mass stars.

A sudden change in compressibility at nearly equal 14 GPa and a rapid increase of resistivity at nearly equal 12 K were detected, whereas magnetic phase transformation and magnetic field dependence of the low-temperature resistivity do not occur at temperatures down to 4.2 K. An interaction between conduction electrons and the two-level systems is suggested to explain the temperature and field dependences of resistivity of the BMG alloy. Although the cause of the unusual change in compressibility at nearly equal 14 GPa is not clear, we believe that it could be linked with the unique electron structure of cerium in the amorphous matrix. An electronic phase transition in BMG alloys, most likely a second-order amorphous-to-amorphous phase transition, is suggested.

Loss of sortase leads to large reductions in virulence, which identifies sortase as a target for the development of antibacterials. By screening 135,625 small molecules for inhibition, we report here that aryl ( beta -amino)ethyl ketones inhibit sortase enzymes from staphylococci and bacilli. Inhibition of sortases occurs through an irreversible, covalent modification of their active site cysteine. Sortases specifically activate this class of molecules via beta -elimination, generating a reactive olefin intermediate that covalently modifies the cysteine thiol. Analysis of the three-dimensional structure of Bacillus anthracis sortase B with and without inhibitor provides insights into the mechanism of inhibition and reveals binding pockets that can be exploited for drug discovery.

The total length of roads for the tests was 186km. Data were obtained for 37,255 effective driving cycles, including 17,216 on arterial roads, 15,444 on residential roads, and 4595 on highways. The impacts of speed and acceleration on fuel consumption and emissions were analyzed. Results show that trucks spend an average of 16.5% of the time in idling mode, 25.5% in acceleration mode, 27.9% in deceleration mode, and only 30.0% at cruise speed. The average emission factors of CO, total hydrocarbons (THC), and NO sub(x) for the selected vehicles are (4.96+/-2.90), (1.88+/-1.03) and (6.54+/-1.90)gkm super(-) super(1), respectively. The vehicle emission rates vary significantly with factors like speed and acceleration. The test results reflect the actual traffic situation and the current emission status of diesel trucks in Shanghai. The measurements show that low-speed conditions with frequent acceleration and deceleration, particularly in congestion conditions, are the main factors that aggravate vehicle emissions and cause high emissions of CO and THC. Alleviating congestion would significantly improve vehicle fuel economy and reduce CO and THC emissions.

Eleven rounds of random mutagenesis and screening via fluorescence-activated cell sorting yielded a GFP mutant containing 20 amino acid substitutions. The mutant protein in fluorinated form showed improved folding efficiency both in vivo and in vitro, and the median fluorescence of cells expressing the fluorinated protein was improved approximately 650-fold in comparison to that of cells expressing fluorinated GFPm. The success of this approach demonstrates the feasibility of engineering functional proteins containing many copies of abiological amino acid constituents.

AN - 68122142; 17625910 AB - The characterization of a bioelectronic composite prepared by molecular wiring of a bacterial photosynthetic reaction center (RC) to a metal (Au) electrode is described. Two unique attachment sites on the protein surface were studied as sites for electrical connections--a polyhistidine tag introduced by site-directed mutagenesis and a native cysteine amino acid residue. These two attachment sites were evaluated independently and found to serve effectively in coupling the protein to the electrode surface asymmetrically. Cyclic voltammetry (CV) was used to monitor protein integrity and confirm protein chemisorption and orientation to the organofunctionalized gold electrode. Single-protein transport measurements made with conductive atomic force microscopy (C-AFM) were used to study the electrical transport. Current-voltage (I-V) curves obtained by wiring the protein at the polyhistidine tag showed diodelike behavior. The cysteine attachment site does not serve as an efficient means to address the protein electrically. Scanning tunneling spectroscopy (STS) performed on RCs coupled at the donor side under both dark- and white-light-illuminated conditions confirmed the C-AFM studies.

CaIrO (sub 3) is orthorhombic (Cmcm, space group 63, Z = 4) with best-fit unit-cell parameters, a = 3.14147(5) Aa, b = 9.87515(19), c = 7.29711(11), and V = 226.3754(78) Aa (super 3) at 1 bar and 300 K. The c-axis of CaIrO (sub 3) has a small compressibility and a large thermal expansion when compared to the other principal axes. Rietveld structure refinement reveals changes in CaIrO (sub 3) as a function of temperature in terms of IrO (sub 6) octahedra distortion. Dissociation of CaIrO (sub 3) at high temperature has possible implications for the post-perovskite MgSiO (sub 3) structure, Earth's lower mantle, and D" layer.

The model simulated the major abrupt vegetation collapse in the southern Sahara at about 5 ka, consistent with the proxy records. Local precipitation, however, shows a much more gradual decline with time, implying a lack of strong positive vegetation feedback on annual rainfall during the collapse. The vegetation change in northern Africa is driven by local precipitation decline and strong precipitation variability. In contrast, the change of precipitation is dominated by internal climate variability and a gradual monsoonal climate response to orbital forcing. In addition, some minor vegetation changes are also simulated in different regions across northern Africa The model also simulated a gradual annual mean surface cooling in the subtropical North Atlantic towards the latest Holocene, as well as a reduced seasonal cycle of SST. The SST response is caused largely by the insolation forcing, while the annual mean cooling is also reinforced by the increased coastal upwelling near the east boundary. The increased upwelling results from a southward retreat of the North Africa monsoon system, and, in turn, an increased northeasterly trade wind. The simulated changes of SST and upwelling are also largely consistent with marine proxy records, albeit with a weaker magnitude in the model. The mismatch between the collapse of vegetation and gradual transition of rainfall suggests that the vegetation collapse is not caused by a strong positive vegetation feedback. Instead, it is suggested that the Mid-Holocene collapse of North African vegetation is caused mainly by a nonlinear response of the vegetation to a precipitation threshold in the presence of strong climate variability. The implication to the modeling and observations is also discussed.

The N- and C-terminal domains are conserved across the family and contain a dimetal-binding motif in a putative active site. YqfO contains an insert in the middle of the protein, present in a minority of bacterial family members. The structure of YqfO was determined at a resolution of 2.2 Aa and reveals conservation of the putative active site. It also reveals the previously unknown structure of the insert, which despite extremely limited sequence conservation, bears great similarity to PII, CutA, and a number of other trimeric regulatory proteins. Our results suggest that this domain acts as a signal sensor to regulate the still-unknown catalytic activity of the more-conserved domains.

The bill - which incorporates efficiency and alternative energy goals, including a 40% increase in vehicle fuel economy by 2020 - is heading to the House of Representatives for more discussions. This paper considers the legacy of the 1975 Energy Policy Conservation Act, the CAFE standards for cars and how new fuel economy standards will impact the automobile industry and the nation. Fuel economy can be achieved through technology but also requires consumer awareness and commitment.

We uncovered the atomic arrangement by real-space modeling of the pair distribution function (PDF) derived from direct Fourier transformation of the total x-ray scattering. The PDF for ferrihydrite synthesized with the use of different routes is consistent with a single phase (hexagonal space group P6 (sub 3) mc; a = approximately 5.95 angstroms, c = approximately 9.06 angstroms). In its ideal form, this structure contains 20% tetrahedrally and 80% octahedrally coordinated iron and has a basic structural motif closely related to the Baker-Figgis delta -Keggin cluster. Real-space fitting indicates structural relaxation with decreasing particle size and also suggests that second-order effects such as internal strain, stacking faults, and particle shape contribute to the PDFs.

The creep rupture life at relatively low applied stresses was shortest in a helium environment containing 500 vppm oxygen (He + O2), while it was the longest in helium containing 675 vppm methane (He + CH4). However, the rupture strain was significantly lower in the He + CH4environment compared to that in pure helium (He) and He + O2. The low rupture strain in the He + CH4 is caused by cleavage fracture. In the He + CH4 environment, the fracture mode was cleavage at lower applied stresses and ductile at higher applied stresses while in the He and He + O2, a ductile fracture was observed at all stress levels. The apparent activation energy for creep was determined in all three environments, and it appears to be independent of stress in the He, dependent in the He + CH4, while in the He + O2 environment the stress dependence could not be conclusively established.

High-throughput, ligation-independent cloning (LIC) vectors used extensively for production and purification of single proteins were modified to allow simultaneous expression of interacting proteins and selective purification of functional complexes. Transfer of the LIC region of vector pMCSG7 (L. Stols, M. Gu, L. Dieckman, R. Raffen, F.R. Collart, M.I. Donnelly. A new vector for high-throughput, ligation-independent cloning encoding a tobacco etch virus protease cleavage site. Protein Expr. Purif. (2002) 25, 8- 15) into commercial vectors with alternative, compatible origins of replication allowed introduction of standard LIC PCR products into the vectors by uniform protocols. Replacement of the His-tag encoding region of pMCSG7 with a sequence encoding the S-tag enabled selective purification of interacting proteins based on the His-tag associated with one member of the complex. When expressed separately and mixed, the ScoAB subunits failed to interact productively; no transferase activity was detected, and S-tagged ScoB failed to co-purify with His-tagged ScoA. Co-expression, in contrast, generated active transferase that catalyzed the predicted reaction. The ScoAB complex was purified by standard high-throughput metal-ion affinity chromatography procedures, crystallized robotically, and its structure was determined by molecular replacement.

Members of the public and politicians are poised for action. The first climate change bills in Congress are expected to emerge later this summer. The rate of global warming can be reduced by removing some carbon dioxide (CO sub(2)) from the atmosphere. The method of CO sub(2) abatement that is most likely to be used on a large scale involves underground injection of CO sub(2) into stable formations. This process is known by several different names: (e.g., carbon sequestration (our preferred term), carbon geosequestration, and carbon capture and storage). If carbon sequestration is conducted in large enough volumes to have a meaningful impact on global warming, it is likely that thousands or tens of thousands of injection wells will need to be developed and permitted in the United States.

Magnetic spheres were prepared by a modified single oil-in-water emulsion-solvent evaporation method utilizing highly- concentrated hydrophobic magnetite and poly(d,l lactide-co-glycolide) (PLGA). Hydrophobic magnetite prepared using oleic acid exhibited high magnetite concentrations (84 wt.%) and good miscibility with biopolymer solvents to form a stable oily suspension. The oily suspension was then emulsified within an aqueous solution containing poly(vinyl alcohol). After rapid evaporation of the organic solvent, we obtained solid magnetic nanospheres. We characterized these spheres in terms of external morphology, microstructure, size and zeta potential, magnetite content and distribution within the nanospheres, and magnetic properties. The results showed good encapsulation where the magnetite distorted the smooth surface morphology only at the highest magnetite concentrations. The mean diameter was 360-370 nm with polydispersity indices of 0.12-0.20. We obtained high magnetite content (40-60%) and high magnetization (26-40 emu/g). The high magnetization properties were obtained while leaving sufficient polymer to retain drugs making these biodegradable spheres suitable as a potential platform for the design of magnetically-guided drug delivery and other in vivo biomagnetic applications.

First, almost all of the radioactivity is initially in the waste form, mainly in the spent nuclear fuel (SNF) or nuclear waste glass. Second, over long periods, after the engineered barriers are degraded, the waste form is a primary control on the release of radioactivity. Thus, it is essential to know the physical and chemical state of the waste form after hundreds of thousands of years. The United States Department of Energy's Yucca Mountain Repository Program has initiated a long-term program to develop a basic understanding of the fundamental mechanisms of radionuclide release and a quantification of the release as repository conditions evolve over time. Specifically, the research program addresses four critical areas: (a) SNF dissolution mechanisms and rates; (b) formation and properties of U6+-secondary phases; (c) waste form-waste package interactions in the near-field; and (d) integration of in-package chemical and physical processes. The ultimate goal is to integrate the scientific results into a larger scale model of source term and near-field processes. This integrated model will be used to provide a basis for understanding the behaviour of the source term over long time periods (greater than 105 years). Such a fundamental and integrated experimental and modelling approach to source term processes can also be readily applied to development of advanced waste forms as part of a closed nuclear fuel cycle. Specifically, a fundamental understanding of candidate waste form materials stability in high temperature/high radiation environments and near-field geochemical/hydrologic processes could enable development of advanced waste forms 'tailored'to specific geologic settings.

We estimate that global biofuel consumption rose from about 1000 Tg in 1850 to 2460 Tg in 2000, an increase of 140%. In the late 19th century, biofuel consumption in North America was very high, similar to 220-250 Tg/yr, because widespread land clearing supplied plentiful fuelwood. At that time biofuel use in Western Europe was lower, similar to 180-200 Tg/yr. As fossil fuels became available, biofuel use in the developed world fell. Compensating changes in other parts of the world, however, caused global consumption to remain remarkably stable between 1850 and 1950 at similar to 1200 plus or minus 200 Tg/yr. It was only after World War II that biofuel use began to increase more rapidly in response to population growth in the developing world. Between 1950 and 2000, biofuel use in Africa, South Asia, and Southeast Asia grew by 170%, 160%, and 130%, respectively.

Consistent with all known uranyl oxide hydrate minerals, metaschoepite [(UO (sub 2) ) (sub 4) O(OH) (sub 6) ](H (sub 2) O) (sub 5) , contains sheets of uranyl polyhedra with H (sub 2) O groups located in the interlayer. Several crystals along the series from metaschoepite to Na-substituted metaschoepite (Na-MS), approximate formula Na[(UO (sub 2) ) (sub 4) O (sub 2) (OH) (sub 5) ](H (sub 2) O) (sub 5) , have been synthesized and their structures have been determined. Each contains sheets of uranyl pentagonal bipyramids that are topologically identical to those in metaschoepite, schoepite and fourmarierite. The sheets are electroneutral in metaschoepite, but substitution of O for OH located at the equatorial vertices of the uranyl polyhedra gives a charged sheet that is balanced by incorporation of Na in the interlayer. Synthesis of crystals of Na-MS from a solution containing approximately 500 ppm Np (super 5+) , followed by analysis of the crystals using laser-ablation inductively coupled-plasma mass-spectroscopy, demonstrated that the crystals incorporate Np. This is in contrast to earlier studies that showed no incorporation of Np (super 5+) in synthetic metaschoepite (which has electroneutral sheets), and supports the hypothesis that Np (super 5+) incorporation is more likely in uranyl oxide hydrates with charged species in the interlayer.

Predicting this behavior in the environment requires an understanding of the mechanisms of arsenate adsorption. In this study, the binding site and adsorption geometry of arsenate on the hematite (012) surface is investigated. The structure and termination of the hematite (012)-water interface were determined by high resolution X-ray reflectivity, revealing that two distinct terminations exist in a roughly 3:1 proportion. The occurrence of multiple terminations appears to be a result of sample preparation, and is not intrinsic to the hematite (012) surface. X-ray standing wave (XSW) measurements were used to determine the registry of adsorbed arsenate to the hematite structure, and thus the binding site and geometry of the resulting surface complex. Arsenate forms a bridging bidentate complex on two adjacent singly coordinated oxygen groups on each of the two distinct terminations present at the hematite surface. Although this geometry is consistent with that seen in past studies, the derived As-Fe distances are longer, the result of the topology of the FeO (sub 6) octahedra on the (0 12) surface. As EXAFS-derived As-Fe distances are often used to determine the adsorption mechanism in environmental samples (e.g., mine tailings, contaminated sediments), this demonstrates the importance of considering the possible sorbent surface structures and arrangements of adsorbates when interpreting such data. As multiple functional groups are present and multiple binding geometries are possible on the hematite (012) surface, the XSW data suggest that formation of bridging bidentate surface complexes on singly coordinated oxygen sites is the preferred adsorption mechanism on this and most other hematite surfaces (provided those surfaces contain adjacent singly coordinated oxygen groups). These measurements also constrain the likely reaction stoichiometry, with only the protonation state of the surface complex undetermined. Although bridging bidentate inner-sphere surface complexes comprised the majority of the adsorbed arsenate present on the hematite (012) surface, there is an additional population of sorbed arsenate species that could not be characterized by the XSW measurements. These species are likely more disordered, and thus more weakly bound, than the bridging bidentate complexes, and may play a role in determining the fate, transport, and bioavailability of arsenate in the environment. Finally, the possibility of obtaining species-specific XSW measurements by tuning the incident beam energy to specific features in a XANES spectrum is described.

In this study, the crystallographic preferred orientation of clay platelets that contributes to elastic anisotropy was determined quantitatively by hard monochromatic X-ray synchrotron diffraction in two different shales from drillholes off the coast of Nigeria. To analyze complicated diffraction images with five different phases (illite/smectite, kaolinite, quartz, siderite, feldspar) and many overlapping peaks, we applied a methodology based on the crystallographic Rietveld method. The goal was to describe the intrinsic physical properties of the sample (phase composition, crystallographic preferred orientation, crystal structure, and microstructure) and compute macroscopic elastic properties by averaging single crystal properties over the orientation distribution for each phase. Our results show that elastic anisotropy resulting from crystallographic preferred orientation of the clay particles can be determined quantitatively.

This result has at least two-fold importance: first, it is a new petrologic technique to examine the behavior of a single sample under a large range of effective oxygen fugacity; and second, it is a mechanism for planetary electric fields to generate potentially significant chemical heterogeneities within planetary interiors. The redox state of Fe and V within a partially melted basaltic andesite was manipulated in situ in a piston-cylinder experiment with a DC power supply providing a source and sink of electrons to the sample. A 1 V electrical potential difference was applied across vanadium-doped synthetic basalt samples for 24 h. at 20 kbar and 1400 degrees C in a specially-designed piston cylinder sample assembly. Three experiments were performed: a control sample with no applied voltage, one with bottom ground and top anode (+1 V), and a third with top ground and bottom anode (+1 V). Synchrotron-based X-ray absorption near edge structure spectroscopy (XANES) was used to provide maps of iron and vanadium oxidation states with 5 mu mm X 5 mu m spatial resolution throughout the recovered samples. Systematic increasing oxidation states of V and Fe were observed approaching the anode. Oxidation states were mapped to corresponding local oxygen fugacities by comparison with a series of samples synthesized under known oxygen fugacity conditions from previous studies. Both Fe and V markers indicate that the 1 V potential drop across the sample induces effective oxygen fugacity perturbations of 10 orders of magnitude. Therefore, it is possible that the presence of modest poloidal electric fields ( approximately 10 (super -6) V/m) within the Earth's outer core may provide an electrochemical driving force for localized charge transfer reactions in certain overlying mantle areas, generating local order-of-magnitude differences in effective oxygen fugacity.

We present in this paper a number of future scenarios of emissions of black carbon (BC) and organic carbon (OC) by world region, which we combine with sulfate (SO sub(4)) assessed in terms of the emissions of its precursor, SO sub(2). We find that aerosol emissions from the household and industrial sectors are likely to decline along almost all future pathways. Transportation emissions, however, are subject to complex interacting forces that can lead to either increases or decreases. Biomass burning declines in many scenarios, but the Amazon rainforests remain vulnerable if unsustainable economic growth persists. East Asia is the key region for primary aerosols, and trends in China will have a major bearing on the direction and magnitude of releases of BC (expected reductions in the range of 640-1290 Gg), OC (reductions of 520-1900 Gg), and SO sub(2) (ranging from an increase of 21 Tg to a reduction of 30 Tg). Analysis of joint BC, OC, and SO sub(2) emission changes identifies a number of key world regions and economic sectors that could be effectively targeted for aerosol reductions.

The recent identification of green rusts as products of the reduction of Fe(III) oxides and oxyhydroxides by Shewanella putrefaciens, a dissimilatory iron-reducing bacterium (DIRB), suggests that green rusts may play a role in the redox cycling of Fe in many aquatic and terrestrial environments. We examined the potential for green rust formation resulting from the bioreduction of lepidocrocite( gamma -FeOOH) by a series of Shewanella species (S. alga BrY, S. amazonensis SB2B, S. baltica OS155, S. denitrificans OS217T, S. loihica PV-4, S. oneidensis MR-1, S. putrefaciens ATCC 8071, S. putrefaciens CN32, S. saccharophilia, and Shewanella sp. ANA-3). All Shewanella species, with the exception of S. denitrificans OS217T, were able to couple the oxidation of formate to the reduction of Fe(III) in lepidocrocite; however there were significant differences among species with respect to the rate and extent of Fe(II) production. Despite these differences, green rust was the only Fe(II)-bearing solid phase formed under our experimental conditions, as indicated by X-ray diffraction, Mossbauer spectroscopy, and scanning electron microscopy. The formation of green rust by Shewanella species isolated from a wide range of habitats and possessing varied metabolic capabilities suggests that under favorable conditions biogenic green rusts may be formed by a diverse array of DIRB.

a key to sustainable utilization of fossil groundwater AN - 742910304; 2010-048659 AB - Rising demands for fresh water supplies in arid lands are leading to excessive exploitation and unsustainable mining of non-renewable fossil groundwater. Using the Nubian Aquifer of Saharan Africa as a test site, we demonstrate an integrated approach to identify areas of discharge that could have gone undetected, and to model extraction that is sustained by natural discharge. Using isotopic and geochemical analyses along with field and remote sensing data we show that discharge of the Nubian Aquifer is occurring on a larger scale, primarily through deep-seated fault systems, and that ascending groundwater discharges into relatively thick alluvial aquifers proximal to the fault complex that defines the River Nile and the Gulf of Suez. We develop a hydrologic model to assess the discharge and to constrain sustainable extraction in the Asyuti area along the River Nile and to demonstrate a replicable model for similar reservoirs. A two-dimensional groundwater flow model was constructed and calibrated against head data from 19 wells. Results point to a significant contribution to the Asyuti groundwater system from rising Nubian groundwater (3.19X10 (super 7) m (super 3) /yr: 75% of incoming flow) and a modest contribution (1.08X10 (super 7) m (super 3) /yr: 25% of incoming flow) from surface runoff. Approximately 2.5X10 (super 7) m (super 3) /yr of groundwater could be used in a sustainable manner in Asyuti. Assuming geologic settings and discharge rates similar to those at Asyuti, we estimate that 70X10 (super 7) m (super 3) /yr of groundwater may be available for sustainable development in similar settings around the River Nile and the Gulf of Suez.

The examples, drawn from late prehistoric and Bronze Age societies that developed at the onset of urbanization, show how small communities might respond to various resource stresses and environmental fluctuations. The computer simulations demonstrate that some households gain resources at the expense of others and the community becomes more economically differentiated through time with some households benefiting at the expense of others. The approaches discussed demonstrate that complex societies were capable of a wide range of responses to stresses that could be absorbed or amplified via a number of social, economic, or demographic processes.

The asymmetric unit contains a hexamer of structurally identical monomers. The monomer is a globular domain with a long beta -hairpin protrusion that distinguishes this structure. This beta -hairpin occupies a central position in the hexamer, and its residues participate in the majority of interactions between subunits of the hexamer. We suggest that the structure of Stm3548 presents a new hexamerization motif. Because the residues participating in interdomain interactions are highly conserved among close members of protein family DUF1355 and buried solvent accessible area for the hexamer is significant, the hexamer is most likely conserved as well. A light scattering experiment confirmed the presence of hexamer in solution.

AN - 61654687; 200720985 AB - In the application of new technologies that address the terrorism problem, an objective is to ensure that the technology does not cause more problems than it solves. Potential new technologies, including convergences of genomics, robotics, information technology, and nanotechnology, might rapidly develop. As with any technological advance, each of these offers a mixture of benefits and risks. At first, a direct approach is reviewed by looking at how these technologies might deter the motive, means, and opportunity for terrorist activities. While there are many potential deterrence applications, other issues are identified that might cause unintended problems in the system. Some of these problems include the possible contribution to terrorist motives by increasing stresses toward divisiveness in society, terrorist means through the development of dual-use technologies, or terrorist opportunities by further developing technological vulnerabilities. Next, a more systemic approach is taken by reviewing a wider range of issues, such as resource availability, management of science and technology, and general societal trends. The balance between technological change and social response is important in realizing benefits while mitigating unintended consequences such as harmful uses through terrorist actions. To explore issues concerning this balance, possible technological development scenarios are reviewed, including the possibility of accelerating or slowing technological development. Some recent recommendations are considered within this context. The need for a balance between technological and social response in this asymmetric situation suggests that the benefits of a rapid technological response against terrorism might not be as large as those observed during World War II.

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.

The freshly cleaved dolomite (104) surface in contact with the saturated solution has a stoichiometric termination, a distinct surface hydration layer and small surface structural displacements, similar to those observed previously at the calcite-water interface. After reaction with supersaturated solutions dolomite is terminated by a two-layer thick Ca-rich film with substantial structural displacements of the cations. With subsequent exposure to a saturated solution this surface was transformed to an interfacial structure different from the freshly cleaved surface, having a reduced density of the outermost surface layer and a Ca-rich second layer. These results provide new insight into the lack of dolomite growth in modern carbonate environments (i.e., the "dolomite problem"), suggesting that this behavior is associated with a combination of thermodynamic and kinetic factors, including (1) growth of compositionally modified epitaxial Ca (sub X) Mg (sub 2-X) (CO (sub 3) ) (sub 2) layers having thicknesses limited by lattice strain, (2) slow incorporation of Mg during layer growth, and (3) partial irreversibility of surface reactions.

The microarray was developed as a universal fingerprint device consisting of 390 genome-independent 9mer probes. The genomes of B. anthracis strains are monomorphic and therefore, typically difficult to distinguish using conventional molecular biology tools or microarray data clustering techniques. Using support vector machines (SVMs) as a supervised learning technique, we show that a low-density fingerprint microarray contains enough information to discriminate between B.anthracis strains with 90% sensitivity using a reference library constructed from six replicate arrays and three replicates for new isolates.

We examined how soil microbial community composition changed with depth and along a successional gradient of native prairie restoration. We predicted that carbon would be the primary control on both microbial biomass and community composition, and that deeper, low-carbon soils would be more similar to low-carbon agricultural soils than to high carbon remnant prairie soils. Soil microbial community composition was characterized using phospholipid fatty acid (PLFA) analysis, and explicitly linked to environmental data using structural equations modeling (SEM). We found that total microbial biomass declined strongly with depth, and increased with restoration age, and that changes in microbial biomass were largely attributable to changes in soil C and/or N concentrations, together with both direct and indirect impacts of root biomass and magnesium. Community composition also shifted with depth and age: the relative abundance of sulfate-reducing bacteria increased with both depth and restoration age, while gram-negative bacteria declined with depth and age. In contrast to prediction, deeper, low-C soils were more similar to high-C remnant prairie soils than to low-C agricultural soils, suggesting that carbon is not the primary control on soil microbial community composition. Instead, the effects of depth and restoration age on microbial community composition were mediated via changes in available phosphorus, exchangeable calcium, and soil water, together with a large undetermined effect of depth. Only by examining soil microbial community composition shifts across sites and down the soil column simultaneously were we able to tease apart the impact of these correlates environmental variables.

Recent developments in x-ray optics at third-generation synchrotron sources have provided a resource for highly sensitive visualization and quantitation of metalloproteins in biological samples. Here, we report the application of x-ray fluorescence microscopy (XFM) toin vitro models of angiogenesis and neurogenesis, revealing a surprisingly dramatic spatial relocalization specific to capillary formation of 80-90% of endogenous cellular copper stores from intracellular compartments to the tips of nascent endothelial cell filopodia and across the cell membrane. Although copper chelation had no effect on process formation, an almost complete ablation of network formation was observed. XFM of highly vascularized ductal carcinomas showed copper clustering in putative neoangiogenic areas. This use of XFM for the study of a dynamic developmental process not only sheds light on the copper requirement for endothelial tube formation but highlights the value of synchrotron-based facilities in biological research.

We found yhhF to be a gene encoding for m super(2)G966 specific 16 S rRNA methyltransferase. Disruption of the yhhF gene by kanamycin resistance marker leads to a loss of modification at G966. The modification could be rescued by expression of recombinant protein from the plasmid carrying the yhhF gene. Moreover, purified m super(2)G966 methyltransferase, in the presence of S-adenosylomethionine (AdoMet), is able to methylate 30 S ribosomal subunits that were purified from yhhF knock-out strain in vitro. The methylation is specific for G966 base of the 16 S rRNA. The m super(2)G966 methyltransferase was crystallized, and its structure has been determined and refined to 2.05Aa sub(.) The structure closely resembles RsmC rRNA methyltransferase, specific for m super(2)G1207 of the 16 S rRNA. Structural comparisons and analysis of the enzyme active site suggest modes for binding AdoMet and rRNA to m super(2)G966 methyltransferase. Based on the experimental data and current nomenclature the protein expressed from the yhhF gene was renamed to RsmD. A model for interaction of RsmD with ribosome has been proposed.

2011-046582 AB - Phosphorus Near Edge X-ray Fluorescence Spectroscopy (P-NEXFS) data were collected on phosphorus containing phases including organic and inorganic compounds and minerals. Although phases containing P in the plus five oxidation state P(V) in a tetrahedral PO (sub 4) structure have similar primary fluorescence peak positions, the size, shape, and positions of secondary spectral features are diagnostic for different compounds and minerals. In particular, calcium phosphates exhibited a notable post-peak shoulder at 2154.5 eV, while oxidized iron phosphates had a distinctive pre-peak feature at 2148 eV. Polyphosphates have a broad secondary peak located approximately 2 eV higher in energy than a similar feature in phosphate esters and diesters. Compounds containing P(V) in structures other than PO (sub 4) tetrahedra such as phosphonates have a primary peak shifted about 1 eV lower than corresponding organo-phosphates. Organo-phosphates with P in the plus three oxidation state P(III) such as phosphines had primary fluorescence peaks shifted still further down in energy (2-3 eV). The substitution of aromatic carbon groups in close proximity to P structures in organic compounds generated both pre- and post-peak features as well as a number of secondary peaks. In addition, X-ray fluorescence mapping of P, Si, Al, Mg, and Na was conducted on a marine sediment sample with sub-micron spatial resolution. Phosphorus was heterogeneously distributed in the sample and not correlated on a broad scale with any other element examined. Much of the P present in the sample was located in small, 0.6-8 mu m size, P-rich domains. Several P-rich regions were examined with P-NEXFS using a focused beam with 60 nm resolution and were found to consist of either calcium phosphate or polyphosphate phases. The presence of significant polyphosphate-dominated regions in a marine sediment sample supports the recent observations that such phases can play an important role in marine P cycling. The combination of fluorescence mapping and P-NEXFS data collection on fine particles provides a powerful new tool for environmental phosphorus studies.

The inelastic method provides specific vibrational information, for example, the phonon density of states, and, in combination with compression data, it permits the determination of sound velocities and Gruneisen parameters under high pressure and high temperature. The Mossbauer method provides hyperfine interactions between the resonant nucleus and electronic environment, such as isomer shifts, quadrupole splittings, and magnetic fields, which provide important information on valence, spin state, and magnetic ordering. Both methods use a nuclear resonant isotope as a probe and can be applied under high pressure and high temperature. The physical mechanism of nuclear resonant scattering and the specifics in applications to Earth materials are presented with reference to several high-pressure studies on iron-bearing compounds.

Sampling branches is a potentially more cost-effective and easier method than sampling tree cores, with less risk of damage to the tree. This approach was tested at Argonne National Laboratory, where phytoremediation is being used to remove tetrachloroethene (PCE), trichloroethene (TCE), and carbon tetrachloride (CCl (sub 4) ) from soil and ground water. The phytoremediation system consists of shallow-rooted willows planted in an area with contaminated soil and deep-rooted poplars planted in an area with clean soil and contaminated ground water. Branch samples were collected from 126 willows and 120 poplars. Contaminant concentrations from 31 soil borings and six monitoring wells were compared to those from branches of adjacent trees. Regression equations with correlation coefficients of at least 0.89 were obtained, which were found to be chemical specific. Kriged profiles of TCE concentration based on soil and willow branch data were developed and showed good agreement. Profiles based on ground water data could not be developed due to lack of sufficient monitoring wells for a meaningful statistical analysis. An analytical model was used to simulate TCE concentrations in tree branches from soil concentrations; the diffusion coefficient for TCE in the tree was used as the fitting parameter and the best-fit value was two orders of magnitude greater than literature values. This work indicates that tree branch sampling is a useful approach to assess contaminant distribution and potentially to determine where to locate monitoring wells or perform detailed soil analysis.

Under the Advanced Fuel Cycle Initiative of the United States Department of Energy (USDOE), studies have been conducted of spent nuclear fuel reprocessing and recycling strategies to evaluate the effects on nuclear waste characteristics and the impact on geological disposal. The first area of emphasis has been on increasing the utilization of space in the repository, where the loading of the repository is limited by the decay heat of the emplaced materials. It has been shown that it is essential to remove plutonium and americium for recycling, since these two elements are the dominant source of the decay heat limiting the loading density of spent nuclear fuel. Once these elements are removed, additional removal of caesium and strontium for separate storage allows further increases in loading density. Alternative strategies involving delay of placement and extended operation of the repository have also been evaluated, since some of the important isotopes have relatively short half-lives and can decay significantly during extended storage. Fuel cycle options, including limited actinide recycle in thermal reactors and continuous, or repeated, actinide recycle in thermal or fast reactors have been studied to quantify the practical increases in utilization of repository space. Limited recycle results in relatively little benefit, while continuous recycle provides the means to achieve large increases in repository loading density. However, with such increases comes the potential to increase the dose rates associated with releases from the repository. Preliminary results indicate that the peak dose rates with increased repository utilization are at most comparable to those for direct disposal of spent fuel.

Tamper-indicating seals and standard data encryption/integrity techniques, however, do not provide sufficient security, especially against electronic and physical attacks in the context of international nuclear safeguards. This article presents an alternative approach for assuring the integrity of monitoring data called the "One-Time Pad of Digits Substitutions" (OPODS). This cipher is a combination of the unbreakable one-time keypad, and the traditional substitution cipher. OPODS provides unbreakable security prior to an adversary trespassing inside nuclear monitoring hardware (even if the trespassing goes undetected), and good security after.

The scaffolds were characterized for structure and morphology by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD) techniques. The scaffolds have a porous nanofibrous morphology with random fibers in the range of 500-700 nm diameters, depending on the composition. FT-IR and XRD showed the presence of nanoHA in the fibers. The surface roughness and diameter of the fibers increased with the presence of nanoHA in biocomposite fiber as evident from AFM images. Tensile testing and nanoindendation were used for the mechanical characterization. The pure collagen fibrous matrix (without nanoHA) showed a tensile strength of 1.68 plus or minus 0.10 MPa and a modulus of 6.21 plus or minus 0.8 MPa with a strain to failure value of 55 plus or minus 10%. As the nanoHA content in the randomly oriented collagen nanofibers increased to 10%, the ultimate strength increased to 5 plus or minus 0.5 MPa and the modulus increased to 230 plus or minus 30 MPa. The increase in tensile modulus may be attributed to an increase in rigidity over the pure polymer when the hydroxyapatite is added and/or the resulting strong adhesion between the two materials. The vapor phase chemical crosslinking of collagens using glutaraldehyde further increased the mechanical properties as evident from nanoindentation results. A combination of nanofibrous collagen and nanohydroxyapatite that mimics the nanoscale features of the extra cellular matrix could be promising for application as scaffolds for hard tissue regeneration, especially in low or nonload bearing areas.

Two major mechanisms, (bio)chemical alteration and physicochemical protection, stabilize soil organic C (SOC) and thereby control its turnover. With (bio)chemical alteration, SOC is transformed by biotic and abiotic processes to chemical forms that are more resistant to decomposition and, in some cases, more easily retained by sorption to soil solids. With physicochemical protection, biochemical attack of SOC is inhibited by organomineral interactions at molecular to millimeter scales. Stabilization of otherwise decomposable SOC can occur via sorption to mineral and organic soil surfaces, occlusion within aggregates, and deposition in pores or other locations inaccessible to decomposers and extracellular enzymes. Soil structure is a master integrating variable that both controls and indicates the SOC stabilization status of a soil. One potential option for reducing SOC turnover and enhancing sequestration, is to modify the soil physicochemical environment to favor the activities of fungi. Specific practices that could accomplish this include manipulating the quality of plant C inputs, planting perennial species, minimizing tillage and other disturbances, maintaining a near-neutral soil pH and adequate amounts of exchangeable base cations (particularly calcium), ensuring adequate drainage, and minimizing erosion. In some soils, amendment with micro- and mesoporous sorbents that have a high specific surface - such as fly ash or charcoal - can be beneficial.

Sentra consists of two principal components, a manually curated list of signal transduction proteins in 202 completely sequenced prokaryotic genomes and an automatically generated listing of predicted signaling proteins in 235 sequenced genomes that are awaiting manual curation. In addition to two-component histidine kinases and response regulators, the database now lists manually curated Ser/Thr/Tyr protein kinases and protein phosphatases, as well as adenylate and diguanylate cyclases and c-di-GMP phosphodiesterases, as defined in several recent reviews. All entries in Sentra are extensively annotated with relevant information from public databases (e.g. UniProt, KEGG, PDB and NCBI). Sentra's infrastructure was redesigned to support interactive cross-genome comparisons of signal transduction capabilities of prokaryotic organisms from a taxonomic and phenotypic perspective and in the framework of signal transduction pathways from KEGG. Sentra leverages the PUMA2 system to support interactive analysis and annotation of signal transduction proteins by the users.

Introduction of yPheRS (T415G) and a mutant yeast phenylalanine amber suppressor tRNA (ytRNA super(Phe) sub(CUA_UG)) into an E. coli expression host allowed site-specific incorporation of three of these analogues (6ClW, 6BrW, and BT) into recombinant murine dihydrofolate reductase in response to amber stop codons with at least 98% fidelity. All three analogues were introduced at the Trp66 position in the chromophore of a cyan fluorescent protein variant (CFP6) to investigate the attendant changes in spectral properties. Each of the analogues caused blue shifts in the fluorescence emission and absorption maxima. The CFP6 variant bearing BT at position 66 exhibited an unusually large Stokes shift (56 nm). An expanded set of genetically encoded Trp analogues should enable the design of new proteins with novel spectral properties.

NMPDR contains the complete genomes of similar to 50 strains of pathogenic bacteria that are the focus of our curators, as well as >400 other genomes that provide a broad context for comparative analysis across the three phylogenetic Domains. NMPDR integrates complete, public genomes with expertly curated biological subsystems to provide the most consistent genome annotations. Subsystems are sets of functional roles related by a biologically meaningful organizing principle, which are built over large collections of genomes; they provide researchers with consistent functional assignments in a biologically structured context. Investigators can browse subsystems and reactions to develop accurate reconstructions of the metabolic networks of any sequenced organism. NMPDR provides a comprehensive bioinformatics platform, with tools and viewers for genome analysis. Results of precomputed gene clustering analyses can be retrieved in tabular or graphic format with one-click tools. NMPDR tools include Signature Genes, which finds the set of genes in common or that differentiates two groups of organisms. Essentiality data collated from genome-wide studies have been curated. Drug target identification and high-throughput, in silico, compound screening are in development.

Through a series of experiments at a pilot scale test facility, we explored the lower limits of groundwater U(VI) that can be achieved by in-situ biostimulation and the effects of dissolved oxygen on immobilized uranium. Weekly 2 day additions of ethanol over a 2-year period stimulated growth of denitrifying, Fe(III)-reducing, and sulfate-reducing bacteria, and immobilization of uranium as U(IV), with dissolved uranium concentrations decreasing to low levels. Following sulfite addition to remove dissolved oxygen, aqueous U(VI) concentrations fell below the U.S. Environmental Protection Agengy maximum contaminant limit (MCL) for drinking water (<30 mg L super(-1) or 0.126 mM). Under anaerobic conditions, these low concentrations were stable, even in the absence of added ethanol. However, when sulfite additions stopped, and dissolved oxygen (4.0-5.5 mg L super(-1)) entered the injection well, spatially variable changes in aqueous U(VI) occurred over a 60 day period, with concentrations increasing rapidly from <0.13 to 2.0 mM at a multilevel sampling (MLS) well located close to the injection well, but changing little at an MLS well located further away. Resumption of ethanol addition restored reduction of Fe(III), sulfate, and U(VI) within 36 h. After 2 years of ethanol addition, X-ray absorption near-edge structure spectroscopy (XANES) analyses indicated that U(IV) comprised 60-80% of the total uranium in sediment samples. At the completion of the project (day 1260), U concentrations in MLS wells were less than 0.1 mM. The microbial community at MLS wells with low U(VI) contained bacteria that are known to reduce uranium, including Desulfovibrio spp. and Geobacter spp., in both sediment and groundwater. The dominant Fe(III)-reducing species were Geothrix spp. JF - Environmental Science & Technology AU - Wu, Wei-Min AU - Carley, Jack AU - Luo, Jian AU - Ginder-Vogel, Matthew A AU - Cardenas, Erick AU - Leigh, Mary Beth AU - Hwang, Chiachi AU - Kelly, Shelly D AU - Ruan, Chuanmin AU - Wu, Liyou AU - Van Nostrand, Joy AU - Gentry, Terry AU - Lowe, Kenneth AU - Mehlhorn, Tonia AU - Carroll, Sue AU - Luo, Wensui AU - Fields, Matthew W AU - Gu, Baohua AU - Watson, David AU - Kemner, Kenneth M AU - Marsh, Terence AU - Tiedje, James AU - Zhou, Jizhong AU - Fendorf, Scott AU - Kitanidis, Peter K AU - Jardine, Philip M AU - Criddle, Craig S AD - Department of Civil and Environmental Engineering, Stanford University, Stanford, California 94305, Environmental Sciences Division, Oak Ridge National Laboratory, P.O.

However, concentrations of fine particulate matter and ozone in Beijing often exceed healthful levels in the summertime. Based on the US EPAs Models-3/CMAQ model simulation over the Beijing region, we estimate that about 34+ACU- of PM+AEAAQA-d2.5+AEA- on average and 35-60+ACU- of ozone during high ozone episodes at the Olympic Stadium site can be attributed to sources outside Beijing. Neighboring Hebei and Shandong Provinces and the Tianjin Municipality all exert significant influence on Beijings air quality. During sustained wind flow from the south, Hebei Province can contribute 50-70+ACU- of Beijings PM+AEAAQA-d2.5+AEA- concentrations and 20-30+ACU- of ozone. Controlling only local sources in Beijing will not be sufficient to attain the air quality goal set for the Beijing Olympics. There is an urgent need for regional air quality management studies and new emission control strategies to ensure that the air quality goals for 2008 are met.

The Laetoli vertebrate fossil fauna is also of great interest because its taxonomic composition, especially in the family Bovidae, differs from that of other East African faunas of comparable age. However, the taphonomic history and paleoecological context of the Upper Laetolil fossil faunal assemblage is not fully understood. Furthermore, the depositional environment of the Upper Laetolil Beds was initially associated with a dry, savanna-like environment characterized by grassland, shrubs, and isolated trees. However, revised stratigraphy and taphonomy at Localities 8 and 9 indicate an existence of more complex depositional environments than those previously described. Fossil faunal remains from the Upper Laetolil Beds are represented by highly variable numbers of skeletal parts dominated by heavily fractured and/or modified distal, proximal, and midshaft fragments of varying sizes, and many isolated teeth. Unlike marine fossil deposits, which furnish thick sections with rich fossil accumulations of invertebrates, the Laetoli deposits are most commonly composed of low-density accumulations with terrestrial faunal assemblages that differ significantly from modern counterparts. Observed changes in faunal composition at Laetoli especially between the Lower and Upper Units, have been noted, but their cause has not been established.

BaCO (sub 3 ) transforms from an alpha orthorhombic Pmcn structure to a trigonal R3m beta -structure at 811 degrees C. The orthorhombic structure is isotypic with aragonite, CaCO (sub 3) . In trigonal BaCO (sub 3) the CO (sub 3) group has one orientation and shows no rotational disorder. In the orthorhombic phase the distances increase while the distances decrease linearly with T. After the 811 degrees C (sub ) phase transition the distances increase while the distances decrease. There is also a 2.8% volume increase at the phase transition.

The measurements were carried out at 300MPa and to 700 degrees C in a gas-medium high-pressure apparatus. On heating, both the elastic bulk (K (sub s) ) and shear moduli (G) decrease linearly to 350 degrees C. By combining with extant thermal expansion data, the values for the room-temperature K (sub s) and G, and their temperature derivatives are as follows: K (sub 0) = 176.3(7)GPa, G (sub 0) = 80.1(2)GPa, (K (sub s) / T) (sub p) (sub ) = - 0.032(3)GPa K (super -1) and (G/ T) (sub p) = - 0.012(1)GPa K (super -1) . Between 350 and 400 degrees C, there are abrupt increases of 1.4% in both the elastic moduli and these closely coincide with the magnetic Curie transition that was observed by thermal analyses at about 360 degrees C.

Results from this study have implications for both uranium remediation (e.g., in situ stabilization) and uranium resource exploration (e.g., near-surface geochemical sampling). The primary uranium ore (coffinite and uraninite hosted in quartzo-feldspathic gneiss) weathers to saprolites containing the same uranium concentration as the underlying ore (approximately 1000 mg U/kg saprolites). In these water saturated (below water table) saprolites the uranium is retained as uranyl phosphates of the meta-autunite group (mainly meta-uranocircite). Above the water table the soils overlying the deposit contain approximately 200 mg uranium per kg soil (20 times higher than uranium concentrations in similar soils formed from unmineralized rocks adjacent to the deposit). In these unsaturated zone soils uranium is retained by two processes: (1) incorporation into barium-strontium-calcium aluminum phosphate minerals of the crandallite group (mainly gorceixite), and (2) sorption of uranium with phosphorous onto iron oxides that coat the surfaces of other soil minerals. Thermodynamic calculations suggest that the meta-autunite group minerals present in the saprolites below the water table are not stable in the unsaturated zone soils overlying the deposit due to the drop in soil pH from approximately 6.0 down to approximately 4.5. Mineralogical observations suggest that, once exposed to the unsaturated environment, the meta-autunite group minerals react to form U(VI)-bearing aluminum phosphates and U(VI) surface complexes or nano-precipitates associated with ferric oxides. These results therefore indicate that models predicting U(VI) speciation in phosphate amended soils must simultaneously account for variations in pH, ion activities (aluminum appears to be particularly important) and surface complexation with iron oxide mineral surfaces.

We therefore developed several simple total- and posttranslational modification-specific, on-chip staining methods to quantitatively assess the quality of gel element protein arrays manufactured with whole-cell lysate in vitro protein fractions derived from two- dimensional liquid-phase fractionation (PF2D) technology. A linear dynamic range of at least 3 logs was observed for protein stains and immobilized protein content, with a lower limit of detection at 8 pg of protein per gel element with Deep Purple protein stain and a field-portable microarray imager. Data demonstrate the successful isolation, separation, transfer, and immobilization of putative transmembrane proteins from Yersinia pestis KIM D27 with the combined PF2D and gel element array method. Internal bovine serum albumin standard curves provided a method to assess on-chip PF2D transfer and quantify total protein immobilized per gel element. The basic PF2D array fabrication and quality assurance/quality control methods described here therefore provide a standard operating procedure and basis for developing whole-proteome arrays for interrogating host-pathogen interactions, independent of sequenced genomes, affinity tags, or a priori knowledge of target cell composition.

While it has long been recognized that paleogeography may potentially influence atmospheric CO (sub 2) via the continental silicate weathering feedback, no numerical simulations have been done, because of the lack of a spatially resolved climate-carbon model. GEOCLIM, a coupled numerical model of the climate and global biogeochemical cycles, is used to investigate the consequences of the Pangea breakup. The climate module of the GEOCLIM model is the FOAM atmospheric general circulation model, allowing the calculation of the consumption of atmospheric CO (sub 2) through continental silicate weathering with a spatial resolution of 7.5 degrees long x 4.5 degrees lat. Seven time slices have been simulated. We show that the breakup of the Pangea supercontinent triggers an increase in continental runoff, resulting in enhanced atmospheric CO (sub 2) consumption through silicate weathering. As a result, atmospheric CO (sub 2) falls from values above 3000 ppmv during the Triassic down to rather low levels during the Cretaceous (around 400 ppmv), resulting in a decrease in global mean annual continental temperatures from about 20 degrees C to 10 degrees C. Silicate weathering feedback and paleogeography both act to force the Earth system toward a dry and hot world reaching its optimum over the last 260 Myr during the Middle-Late Triassic. In the super continent case, given the persistent aridity, the model generates high CO (sub 2) values to produce very warm continental temperatures. Conversely, in the fragmented case, the runoff becomes the most important contributor to the silicate weathering rate, hence producing a CO (sub 2) drawdown and a fall in continental temperatures. Finally, another unexpected outcome is the pronounced fluctuation in carbonate accumulation simulated by the model in response to the Pangea breakup. These fluctuations are driven by changes in continental carbonate weathering flux. Accounting for the fluctuations in area available for carbonate platforms, the simulated ratio of carbonate deposition between neritic and deep sea environments is in better agreement with available data.

The remaining non-metallic fraction, commonly called shredder residue is presently land-filled. Over four and a half million metric tonnes of shredder residue is generated in the United States annually and essentially all of it is landfilled. About 15 million tonnes are generated worldwide. Shredder residue contains, among other materials, polymers that could be recovered and recycled. Argonne National Laboratory is developing technology for producing revenue streams, such as plastics, from shredder residue. This paper describes a process developed by Argonne National Laboratory for the separation and recovery of plastics from shredder residue. The process consists of two parts. First, the plastics are mechanically separated from the shredder residue as a mixed polymer concentrate and then the individual plastics are separated from the polymer concentrate via a froth flotation process. The process has been demonstrated in a mechanical separation pilot plant that has a design capacity of 1.8 tonnes/hour followed by a froth flotation pilot plant that has a capacity of 500 kg/hour. Preliminary process economic analyses indicate that the process is potentially economical.

The report evaluates management policy and related issues regarding scrap metal generated in regulated facilities that have been under radiological control or have radiological concerns. It has been estimated that more than 9 million metric tons of scrap metal of all types that have been associated with the production or use of radioactive materials will be generated during the coming decades at various facilities across the United States. Currently, disposition of such metal has encountered particular obstacles, primarily because of the lack of a consistent disposition policy, systematic regulatory provisions, and, above all, public understanding. Without clarity in the regulatory passage, much of the scrap metal, including metal that has not been contaminated, could be mischaracterized as low-level radioactive waste, resulting in a costly disposition operation. NCRP Report No. 141 identifies this general category of metal as "potentially radioactive scrap metal" (PRSM) and discusses the viable disposition options for facilitating its management. Because much of the PRSM has been found to contain very low residual radioactivity or even none at all, one consideration is to release such metal outside of the radiological control framework. This would require the development and implementation of a set of strict release standards in the United States that would necessarily be risk-based and supported by a comprehensive management scheme. Developing a policy of this kind, however, would entail the resolution of many issues, not the least of which would be public acceptance, including that of the metal industry, of the possible recycling of PRSM in the general commerce.

The 3Y- TZP/40 vol.% HA composites were fabricated by conventional ceramic processing by cold pressing premixed 3Y-TZP and HA powders into pellets. Densification ([asymptotic to]90%) of composites was achieved by sintering composite powder compacts at 1450 not equal to for 5 h. Optimum self-joining of 3Y-TZP/40 vol.% HA composites was obtained at 1300 not equal to for a strain rate of 5 x 10 super(-5)/s. The flow stress during joining was 40 MPa. Microstructural and mechanical characterizations of the joint interface demonstrated that there were no discernible differences between the joint and the composite material away from the interface.

2006-085623 AB - Neighborite (NaMgF (sub 3) ) with the perovskite structure, transforms to a post-perovskite (ppv) phase between 27 and 30 GPa. The ppv phase is observed to the highest pressures achieved (56 GPa) at room temperature and transforms to an as yet unknown phase upon heating. Rietveld structure refinement using monochromatic synchrotron X-ray diffraction data provide models for the perovskite and post-perovskite structures at high pressure. The refined models at 27(1) GPa indicate some inter-octahedral F-F distances rival the average intra-octahedral distance, which may cause instability in the perovskite structure and drive the transformation to the post-perovskite phase. The ratio of A-site to B-site volume (V (sub A) /V (sub B) ) in perovskite structured NaMgF (sub 3) (ABX (sub 3) ), spans from 5 in the zero-pressure high-temperature cubic perovskite phase to 4 in this high-pressure perovskite phase at 27(1) GPa, matching the V (sub A) /V (sub B) value in post-perovskite NaMgF (sub 3) . Using Rietveld refinement on post-perovskite structure models, we observe discrepancies in pattern fitting, which may be described in terms of development of sample texture in the diamond-anvil cell, recrystallization, or a change of space group to Cmc2 (sub 1) , a non-isomorphic subgroup of CMCM:the space group describing the structure of CaIrO (sub 3) .

Using the 4-site non-electrostatic model of Fein et al. [Fein, J. B., Boily, J.-F., Yee, N., Gorman-Lewis, D., Turner, B. F., 2005. Potentiometric titrations of Bacillus subtilis cells to low pH and a comparison of modeling approaches. Geochim. Cosmochim. Acta 69 (5), 1123-1132.] to describe the bacterial surface reactivity to protons, our bulk enthalpy measurements can be used to determine the following site-specific enthalpies of proton adsorption for Sites 1-4, respectively: -3.5 + or - 0.2, -4.2 + or - 0.2, -15.4 + or - 0.9, and -35 + or - 2 kJ/mol, and these values yield the following third law entropies of proton adsorption onto Sites 1-4, respectively: +51 + or - 4, +78 + or - 4, +79 + or - 5, and +60 + or - 20 J/mol K. An alternative data analysis using a 2-site Langmuir-Freundlich model to describe proton binding to the bacterial surface (Fein et al., 2005) resulted in the following site-specific enthalpies of proton adsorption for Sites 1 and 2, respectively: -3.6 + or - 0.2 and -35.1 + or - 0.3 kJ/mol. The thermodynamic values for Sites 1-3 for the non-electrostatic model and Site 1 of the Langmuir-Freundlich model of proton adsorption onto the bacterial surface are similar to those associated with multifunctional organic acid anions, such as citrate, suggesting that the protonation state of a bacterial surface site can influence the energetics of protonation of neighboring sites. Our bulk Cd enthalpy data, interpreted using the 2-site non-electrostatic Cd adsorption model of Borrok et al. [Borrok, D., Fein, J. B., Tischler, M., O'Loughlin, E., Meyer, H., Liss, M., Kemner, K. M., 2004b. The effect of acidic solutions and growth conditions on the adsorptive properties of bacterial surfaces. Chem. Geol. 209 (1-2), 107-119.] to account for Cd adsorption onto B. subtilis, yield the following site-specific enthalpies of Cd adsorption onto bacterial surface Sites 2 and 3, respectively: -0.2 + or - 0.4 and +14.4 + or - 0.9 kJ/mol, and the following third law entropies of Cd adsorption onto Sites 2 and 3, respectively: +57 + or - 4 and +128 + or - 5 J/mol K. The calculated enthalpies of Cd adsorption are typical of those associated with Cd complexation with anionic oxygen ligands, and the entropies are indicative of inner sphere complexation by multiple ligands. The experimental approach described in this study not only yields constraints on the molecular-scale mechanisms involved in proton and Cd adsorption reactions, but also provides new thermodynamic data that enable quantitative estimates of the temperature dependence of proton and Cd adsorption reactions.

A fundamental understanding of adsorption processes is desired in order to predict the fate of contaminants in complexes systems and to generalize about the behavior of these elements in the environment. The adsorption of arsenate (AsO (sub 4) (super 3-) ) at pH 5 on the (012) surfaces of corundum and hematite was studied using resonant anomalous X-ray reflectivity (RAXR). Two distinct sorbed arsenate species were observed in roughly equal proportions: an inner-sphere species consistent with a bridging bidentate complex, and an outer-sphere species, presumably adsorbed via hydrogen bonding. The relative fraction of arsenate adsorbed in the outer-sphere complex was generally independent of the arsenate concentration in solution. These results suggest that outer-sphere arsenate adsorption may be a significant sequestration mechanism that has been largely overlooked in past studies and whose impacts on the fate and bioavailability of arsenic need further evaluation.

The samples come from hydrothermal gold deposits: the Archean Drysdale deposit in Kalgoorlie, Western Australia (DRY1) and the Caledonian, intrusion-related Stepnyak deposit in Kazakhstan (USP31). Laser-ablation ICP-MS analyses reveal that both samples are characterized by bell-shape chondrite-normalized REE patterns with a maximum enrichment around Eu, and a small positive or no Eu anomaly. USP31 displays a complex zoning between this pattern and a strongly LREE-enriched pattern with a strong positive Eu-anomaly. The XANES spectroscopy reveals the coexistence of Eu (super 2+) and Eu (super 3+) in both scheelite samples DRY1 and USP31. The oxidation of Eu in USP31 appears to be inhomogeneous within a single crystal, with zones containing a mixture of Eu (super 2+) and Eu (super 3+) and zones containing more than 90% Eu (super 2+) . This study shows that it is possible to obtain semiquantitative element-distribution maps for LREE as well as, in optimal conditions, EuL (sub 3) XANES spectra on a bending magnet beamline equipped with a solid-state detector.

Arsenic in aerobic environments is predominantly arsenate, however under reducing conditions arsenite species dominate. In anoxic or sulfidic environments thioarsenite ((As(OH) (sub x) (SH) (sub y) (super z-) ) species along with arsenite are known to play key roles in arsenic speciation. Although thioarsenite species are know to be important in sulfidic environments, little is know about their formation, structure, chemistry, and their stability in the environment. In particular, information is sparse relating to the redox behavior of arsenate and arsenite in the presence of aqueous sulfide and at variable pH. In order to address these questions a series of solutions containing arsenate in the presence of sulfide species and at variable pH were analyzed using extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge spectroscopy (XANES) analysis. With these techniques it was possible to obtain kinetic information about the reductive precipitation of arsenic and changes in speciation of arsenate to arsenite and/or thioarsenite with time. In addition, structural data pertaining to thioarsenite in solution and in solid phase were obtained. The results of these experiments will be presented.

The objective of this study was to characterize patterns of soil nutrients, soil respiration and N mineralization with stand development, as well as to determine the mechanisms driving those patterns. We measured in situ N mineralization and soil respiration monthly during the 2002 growing season and used multiple regression analysis to determine the important factors controlling these processes. Growing-season soil respiration rates ranged from a low of 156 g C/m super(2 )in the 7-year-old stand to a high of 254 g C/m super(2 )in the 22-year-old stand, but exhibited no clear pattern with stand age. In general, soil respiration rates peaked during the months of July and August when soil temperatures were highest. We used a modified gamma function to model a temporal trend in total N mineralization (total N mineralization = 1.853-0.276 x age x e super(-0.814) super( x ) super(age); R super(2) = 0.381; P = 0.002). Total N mineralization decreased from 2.8 g N/m super(2) in the 1-year-old stand to a minimum value of 0.5 g N/m super(2) in the 14-year-old stand, and then increased to about 1.5 g N/m super(2) in mature stands. Changes in total N mineralization were driven by a transient spike in N turnover in the mineral soil immediately after wildfire, followed by a gradual accrual of a slow-cycling pool of N in surface organic horizons as stands matured. Thus, in Michigan jack pine forests, the accumulation of surface organic matter appears to regulate N availability following stand-replacing wildfire.

In the current study, Affymetrix S. aureus GeneChips were used to define transcriptome changes in response to cold shock, heat shock, stringent, and SOS response-inducing conditions. Additionally, the RNA turnover properties of each response were measured. Each stress response induced distinct biological processes, subsets of virulence factors, and antibiotic determinants. The results were validated by real-time PCR and stress-mediated changes in antimicrobial agent susceptibility. Collectively, many S. aureus stress-responsive functions are conserved across bacteria, whereas others are unique to the organism. Sets of small stable RNA molecules with no open reading frames were also components of each response. Induction of the stringent, cold shock, and heat shock responses dramatically stabilized most mRNA species. Correlations between mRNA turnover properties and transcript titers suggest that S. aureus stress response-dependent alterations in transcript abundances can, in part, be attributed to alterations in RNA stability. This phenomenon was not observed within SOS-responsive cells.

7061880 AB - The pikromycin (Pik)/methymycin biosynthetic pathway of Streptomyces venezuelae represents a valuable system for dissecting the fundamental mechanisms of modular polyketide biosynthesis, aminodeoxysugar assembly, glycosyltransfer, and hydroxylation leading to the production of a series of macrolide antibiotics, including the natural ketolides narbomycin and pikromycin. In this study, we describe four x-ray crystal structures and allied functional studies for PikC, the remarkable P450 monooxygenase responsible for production of a number of related macrolide products from the Pik pathway. The results provide important new insights into the structural basis for the C10/C12 and C12/C14 hydroxylation patterns for the 12-(YC-17) and 14-membered ring (narbomycin) macrolides, respectively. This includes two different ligand-free structures in an asymmetric unit (resolution 2.1 Aa) and two co-crystal structures with bound endogenous substrates YC-17 (resolution 2.35 Aa)or narbomycin (resolution 1.7 Aa). A central feature of the enzyme-substrate interaction involves anchoring of the desosamine residue in two alternative binding pockets based on a series of distinct amino acid residues that form a salt bridge and a hydrogen-bonding network with the deoxysugar C3' dimethylamino group. Functional significance of the salt bridge was corroborated by site-directed mutagenesis that revealed a key role for Glu-94 in YC-17 binding and Glu-85 for narbomycin binding. Taken together, the x-ray structure analysis, site-directed mutagenesis, and corresponding product distribution studies reveal that PikC substrate tolerance and product diversity result from a combination of alternative anchoring modes rather than an induced fit mechanism.

Batteries are a key enabling technology for the development of clean, fuel-efficient vehicles and are key to making today's hybrid electric vehicles a success Fuel cells are the key enabling technology for a future hydrogen economy and have the Potential to revolutionize the way we power our nations, offering cleaner, more efficient alternatives to technology. Additionally fuel cells are significantly more energy efficient than combustion-based power generation technologies. Fuel cells are projected to have energy efficiency twice that internal combustion engines. However before fuel cells can realize their potential, significant challenges remain. The two most important are cost and durability for both automotive stationary applications. Recent electrocatalyst developments have shown that Pt alloy catalysts have increased activity and greater durability than Pt catalysts. The durability of convertional fluorocarbon membranes is improving, and hydrocarbon-based membranes have also shown promise of equaling the performance of fluorocarbon membranes at lower cost. Recent announcements have also provided indications that fuel cells can start from freezing conditions without significant deterioration. Hydrogen storage systems for vehicles are inadequate to meet customer driving range expectations (>300 miles or 500 km) without intrusion into vehicle cargo or passenger space. The United States Department of Energy has established three centers of Excellence for hydrogen storage materials development The centers are focused on complex metal hydrides that can be regenerated onboard a vehicle, chemical hydrides that require off-board reprocessing, and carbon-based storage materials. Recent developments have shown progress toward the 2010 DOE targets. In addition DOE has established an independent storage material testing center to verify storage capacity of promising materials. These developments point to a viable path to achieving the DOE/FreedomCAR cost and performance goals. The transition to hydrogen-powered fuel cell vehicles will occur over the next 10-15 years.

Its use as a tracer of oceanic export via sinking particles has stimulated a rapidly increasing number of studies that require analyses of (super 234) Th in both marine and freshwater systems. The original (super 234) Th method is labor intensive. Thus, there has been a quest for simpler techniques that require smaller sample volumes. Here, we review current methodologies in the collection and analysis of (super 234) Th from the water column, discuss their individual strengths and weaknesses, and provide an outlook on possible further improvements and future challenges. Also included in this review are recommendations on calibration procedures and the production of standard reference materials as well as a flow chart designed to help researchers find the most appropriate (super 234) Th analytical technique for a specific aquatic regime and known sampling constraints.

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.

Recent proxy data analyses suggest that some aspects of climate change within the Cretaceous appear to be decoupled from CO (sub 2) evolution at the geological time scale. Here, we investigate the impact of paleogeography on the global climate with the climate model FOAM, using a Early, Mid and Late Cretaceous continental configuration. We find that changes in geography from the Early to Mid-to-Late Cretaceous cause a large decrease of the seasonal cycle. First order identified processes are the decreased continentality of the mid-to-high latitudes from the Mid Cretaceous and the increase of the latent heat transport into the winter hemisphere which induce a wetter and a cloudier atmosphere capable of diminishing the winter cooling of the continents. Owing to the modifications of the seasonal cycle in response to the tectonic forcing, the equator-to-pole thermal gradient is reduced from the Early to Mid-to-Late Cretaceous. We nevertheless still do not succeed in simulating warm enough polar temperatures and a definitive theory still waits for an integrated approach explicitly accounting for each factor influencing the thermal gradient (ocean dynamics, stratospheric clouds, and vegetation). Our study also suggests a mechanism that can weaken the correlation between CO (sub 2) and climate changes during the Cretaceous as evolving geography from the Early to Late Cretaceous, through the response of the water cycle and the changes in the thermal gradient, results in a 3.8 degrees C global warming at a constant atmospheric CO (sub 2) level. This demonstrates that the paleogeography may affect the relation between pCO (sub 2) and the climate history and consequently has to be accounted for when linking the atmospheric CO (sub 2) evolution and the climate record at geological time scales.

We show that the inter-annual trend in solar radiation between 1980 and 2000 mirrors the trend in primary emissions of SO sub(2) and black carbon, which together contribute about one-third of global average aerosol optical depth. Combined global emissions of these two species peaked in 1988-1989. The two-decadal rate of decline in aerosol loading resulting from these emission changes, 0.13% yr super(-1), can be compared with the reported increase in solar radiation of 0.10% yr super(-1) in 1983-2001. Regional patterns of aerosol and radiation changes are also qualitatively consistent. We conclude that changes in the aerosol burden due to changing patterns of anthropogenic emissions are likely contributing to the trends in surface solar radiation.

The crystal structure of mouse hepatitis virus strain A59 (MHV-A59) nsp15 is reported at 2.15-Aa resolution. nsp15 is an XendoU endoribonuclease and is the first one from this family to have its structure unveiled. The MHV-A59 nsp15 monomer structure has a novel protein fold. Two nsp15 trimers form a back-to-back hexamer that is believed to be the functional unit. The structure reveals the catalytic site including the highly conserved residues His262, His277, and Lys317, which is supported by mutagenesis analysis. Gel filtration and enzyme activity assays confirmed that the hexamer is the active form for nsp15 and demonstrate the specificity of nsp15 for uridylate. The high sequence conservation of nsp15 in coronaviruses, including that of severe acute respiratory syndrome, suggests that this protein may provide a new target for the design of antiviral therapeutics.

AN - 68612023; 16491121 AB - To gain insight into the function of human protein kinase X (PrKX), a signal-transduction protein required for macrophage differentiation, we identified regulatory subunit I alpha of protein kinase A, T54 and Smad6 as partners for this protein using a yeast two-hybrid interaction screen. Interactions between PrKX and these proteins were substantiated by co-immunoprecipitation. Interaction between Smad6 and PrKX was also confirmed in human myeloid HL-60 cells following their phorbol 12-myristate 13-acetate (PMA)-induced differentiation into macrophages. In vitro phosphorylation assays demonstrated that PrKX phosphorylates Smad6 at a serine residue. Mutagenesis of this site resulted in abrogation of PrKX phosphorylation. Both PrKX and Smad6 were shown to be co-localized to the nuclear compartment of HL-60 cells during their macrophage differentiation where PrKX levels are induced and Smad6 protein levels remain relatively constant while levels of serine phosphorylation of Smad6 increase. By using in vitro electrophoretic mobility shift assays and in vivo chromatin immunoprecipitation, we also demonstrate that during macrophage differentiation Smad6 displays an increased binding to the human osteopontin, Id2, and Hex gene promoters, which correlates to an observed increased expression of these genes. Finally, vector-based RNA interference experiments established that both Smad6 and PrKX proteins are required for PMA-induced cell attachment and spreading.

AN - 68712851; 16889378 AB - We conducted a mobility chains, or well-to-wheels (WTW), analysis to assess the energy and emission benefits of cellulosic biomass for the U.S. transportation sector in the years 2015-2030. We estimated the life-cycle energy consumption and emissions associated with biofuel production and use in light-duty vehicle (LDV) technologies by using the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model. Analysis of biofuel production was based on ASPEN Plus model simulation of an advanced fermentation process to produce fuel ethanol/protein, a thermochemical process to produce Fischer-Tropsch diesel (FTD) and dimethyl ether (DME), and a combined heat and power plant to co-produce steam and electricity. Our study revealed that cellulosic biofuels as E85 (mixture of 85% ethanol and 15% gasoline by volume), FTD, and DME offer substantial savings in petroleum (66-93%) and fossil energy (65-88%) consumption on a per-mile basis. Decreased fossil fuel use translates to 82-87% reductions in greenhouse gas emissions across all unblended cellulosic biofuels. In urban areas, our study shows net reductions for almost all criteria pollutants, with the exception of carbon monoxide (unchanged), for each of the biofuel production option examined. Conventional and hybrid electric vehicles, when fueled with E85, could reduce total sulfur oxide (SO(x)) emissions to 39-43% of those generated by vehicles fueled with gasoline. By using bio-FTD and bio-DME in place of diesel, SO(x) emissions are reduced to 46-58% of those generated by diesel-fueled vehicles. Six different fuel production options were compared. This study strongly suggests that integrated heat and power co-generation by means of gas turbine combined cycle is a crucial factor in the energy savings and emission reductions.

AN - 68088031; 16495082 AB - Many proteins require the binding of trace metals such as Ca, Fe, Cu, or Zn, which may modulate their structure, function, or activity. To determine if there were any overall changes in metalloprotein distribution or metal concentration during the process of macrophage differentiation we induced human myeloid HL-60 leukemia cells with phorbol 12-myristate 13-acetate (PMA) and quantitatively mapped their metal content using hard X-ray fluorescence micro-analysis. We found a transient increase in the zinc content of HL-60 cell nuclei during the early stages of differentiation induction. This finding was confirmed by spectrofluorometry in HL-60 cells and extended to U-937 leukemia cells. A role for protein kinase C-beta (PKC-beta) in this process was established by examining zinc content in an HL-60 variant, HL-525, which is PKC-beta deficient, and in HL-525 cells in which PKC-beta was restored by stable overexpression. Chemical chelation of both Cu and Zn served to inhibit macrophage differentiation in HL-60 cells, indicating a requirement for these metals during this process. Finally, we demonstrate that growth of HL-60 cells in a low-zinc environment removes their susceptibility to PMA-induced differentiation, and that this capacity can be partially restored by the addition of exogenous zinc.

AN - 57657882; 421316 AB - New multimodel simulations of Bronze Age Mesopotamian settlement system dynamics, using advanced object-based simulation frameworks, are addressing fine-scale interaction of natural processes (crop growth, hydrology, etc.) and social processes (kinship-driven behaviors, farming and herding practices, etc.) on a daily basis across multigenerational model runs. Key components of these simulations are representations of initial settlement populations that are demo-graphically and socially plausible, and detailed models of social mechanisms that can produce and maintain realistic textures of social structure and dynamics over time. The simulation engine has broad applicability and is also being used to address modern problems such as agroeconomic sustainability in Southeast Asia. This article describes the simulation framework and presents results of initial studies, highlighting some social system representations.

Structural relaxations of atom positions in the 2M (sub 1) muscovite were small (< or =0.07Aa) and occurred over a distance of 30 to 40 Aa perpendicular to the interface. Cations in all solutions were sorbed dominantly in the first and second solution layers adjacent to the mineral surface. The derived heights of the first solution layer in KCl and CsCl solutions, 1.67(6)-1.77(7) and 2.15(9)-2.16(2) Aa, respectively, differ in magnitude by the approximate difference in crystallographic radii between K and Cs, and correspond closely to the interlayer cation positions in bulk K- and Cs-mica structures. The first solution layer heights in CaCl (sub 2) and BaCl (sub 2) solutions, 2.46(5)-2.56(11) and 2.02(5) Aa, respectively, differ in a sense opposite to that expected based on crystallographic or hydrated radii of the divalent cations. The derived ion heights in all solutions imply that there is no intercalated water layer between the first solution layer and the muscovite surface. Molecular compositions were assigned to the first two solution layers in the electron density profiles using models that constrain the number density of sorbed cations, water molecules, and anions by considering the permanent negative charge of the muscovite and average solution density. The models result in partial charge balance (at least 50%) by cations sorbed in the first two layers in the 0.01 m solutions and approximately full charge balance in the 0.5m solutions. Damped oscillations of model water density away from the first two solution layers agree with previous X-ray reflectivity results on the muscovite (001) surface in pure water.

However, only about 800 tonnes per year can be explained by direct anthropogenic emissions from China, which is by far the largest emitting nation in the region. There are quite high uncertainties (ñ40-50 percent) associated with this estimate, however, especially associated with mercury releases from metal extraction processes (about a factor of 2-4). This paper examines the likely magnitude of emissions from other sources of mercury and compares the estimated total emissions with fluxes inferred from observations and modeling studies. Because of rapid growth in coal use and industrial production in the region in recent years, it is important to normalize the time periods of compared data sources. Additional emission sources considered, some of which should be considered quite tentative and preliminary, include: natural sources (soil, vegetation, volcanic, and geothermal), re-emission of previously deposited mercury, previously unconsidered anthropogenic sources, emissions from other East Asian countries, and global background mercury. The paper constrains the source magnitudes within bounds of predicted uncertainty, as a guide to more detailed source characterizations in the future. These preliminary data may also prove helpful for improved modeling of trans-Pacific and inter- hemispheric transport of Asian mercury.

The system was designed specifically for a former government facility where a large carbon tetrachloride plume in groundwater is being discharged to surface water in a downgradient creek. Contamination levels exceed regulatory limits in both groundwater and surface water. The plume, which is more than 1,000 meter long and 300 meter wide, resulted from activities during 1950s and 1960s. The remediation system combines (1) hot- spot hydraulic control involving extraction of groundwater and treatment with a modified spray system that irrigates recreational lands, (2) interception of the carbon tetrachloride plume before the contaminated groundwater enters the creek through use of phytodegradation technology (including deep-rooted trees planted in wells), and (3) supplemental treatment by an engineered wetland immediately downgradient of the contaminated-groundwater discharge zone. To meet treatment goals, the systematic design process involved determination of design parameters through simulation of existing surface water runoff, evapotranspiration from the various vegetation types, groundwater flow, and contaminant transport; and selection of appropriate vegetation species and components for the engineered phytoremediation system and constructed wetland. Throughout system design, the remedial systems were integrated to (1) minimize interference from clean surface water and infiltrating soil water, while optimizing direct uptake of contaminated groundwater by the phytoremediation system; (2) exploit multiple treatment effects by reducing the hot-spot contaminant concentration and coupling the phytoremediation system with the supplemental wetland treatment system; (3) meet requirements for low maintenance; and (4) maximize benefits to the ecosystem and local community. This large-scale, integrated remediation system was implemented in spring-summer 2005 and is now being monitored through use of various advanced techniques.

Total RNA was extracted from subsurface sediments and interrogated directly, without a PCR step. Bead array validation studies with total RNA derived from 24 isolates indicated that the behavior and response of the 16S rRNA-targeted oligonucleotide probes could not be predicted based on the primary nucleic acid sequence. Likewise, signal intensity (absolute or normalized) could not be used to assess the abundance of one organism (or rRNA) relative to the abundance of another organism (or rRNA). Nevertheless, the microbial community structure and dynamics through time and space and as measured by the rRNA-targeted bead array were consistent with previous data acquired at the site, where indigenous sulfate- and iron-reducing bacteria and near neighbors of Desulfotomaculum were the organisms that were most responsive to a change in injected acetate concentrations. Bead array data were best interpreted by analyzing the relative changes in the probe responses for spatially and temporally related samples and by considering only the response of one probe to itself in relation to a background (reference) environmental sample. By limiting the interpretation of the data in this manner and placing it in the context of supporting geochemical and microbiological analyses, we concluded that ecologically relevant and meaningful information can be derived from direct microarray analysis of rRNA in uncharacterized environmental samples, even with the current analytical uncertainty surrounding the behavior of individual probes on tunable bead arrays.

It was discovered a long time ago and its use in food preservation and processing and as a specialty chemical has grown over the years with current production of about 120 000 t yr-1. Its potential as a major chemical feedstock, derived from renewable carbohydrates by sustainable technologies, to make plastics, fibers, solvents and oxygenated chemicals, had also been recognized. Recently, new technologies have emerged that can overcome major barriers in separations and purification and processing. Advances in electrodialysis (ED) and bipolar membranes and one particular process configuration termed the double ED process, a specific combination of desalting ED followed by water-splitting ED with bipolar membranes, has given very promising results, showing a strong potential for an efficient and economic process for recovery and purification of lactic acid without generating a salt waste. For the production of polymers, several advances in catalysts and process improvements have occurred in the technology to produce dilactide and its polymerization to produce plastics and fibers by Natureworks LLC, which is the leader in lactic polymer technology and markets. Other advances in esterification technology with pervaporation and development of biosolvent blends also have a high potential for green solvents in many applications. Recently, a considerable amount of pioneering effort in technology, product development and commercialization has been expended by several companies. To overcome the barriers to replace long-established petroleum-derived products, further real support from consumer, regulatory and government organizations is also needed.

(Adventus) has developed a combination of controlled-release solid carbon and zero valent iron (ZVI) particles to yield a highly effective material for stimulating the reductive dechlorination of otherwise persistent organic solvents present in groundwater. The materials are known as EHC, and can be employed as fill material for permeable reactive barriers or injected into groundwater and contaminant source zones in a variety of ways. Following placement of EHC into the subsurface environment, indigenous heterotrophic bacteria consume the organic component of EHC (processed fibrous organic material) and consume dissolved oxygen thereby reducing the redox potential in groundwater. In addition, these bacteria ferment carbon and release a variety of volatile fatty acids (acetic, propionic, butyric) into the groundwater plume which serve as electron donors for other bacteria, including dehalogenators and halorespiring species. Finally, the small ZVI particles (i.e., between 10 and 50 *m) provide substantial reactive surface area that stimulates direct chemical dechlorination and an additional drop in the redox potential of the groundwater. These physical, chemical, and biological processes combine to create a strongly reducing (e.g., -600 mV Eh) environment that stimulates both chemical and microbiological dechlorination of solvents in groundwater. In situ chemical reduction (ISCR) is defined as the combined effect of stimulated biological oxygen consumption (via "fermentation" of complex organic carbon sources), direct chemical reduction with reduced metals, and the corresponding enhanced decomposition reactions that are realized at the lowered redox (Eh) conditions. These combined effects are unique to EHC, technology. EHC can be safely and easily applied to the subsurface environment in number of ways for the treatment of chlorinated volatile organic compounds (CVOCs), chlorinated organic pesticides, heavy metals and other persistent compounds (e.g., perchlorate).

This inventory improves and updates the a priori CO emission inventory prepared in support of NASA's TRACE-P mission in the spring of 2001. Analysis of CO observations using chemical transport models in inverse and forward modes suggested that China's emissions were underestimated by about 50%. We have reexamined the source characteristics and conclude that emissions from cement kilns, brick kilns, and the iron and steel industry were underestimated. Our new estimate for China's CO emissions in 2001 is 157 Tg, 36% higher than the TRACE-P estimate for the year 2000 of 116 Tg. Bottom-up and modeled emission estimates are now in good agreement, which represents a major success story for the TRACE- P mission. The new inventory has been gridded at 30 min x 30 min resolution and tested with the CFORS/STEM-2K1 model, considerably improving the correlation between model predictions and observations (bias reduced from 27% to 9%). Propagation-of-error estimates in the new inventory yield an uncertainty of plus or minus 68% (95% confidence intervals), lower than the TRACE-P value of plus or minus 156%; however, the good agreement with results from inverse and forward models implies a greater level of confidence than this. The largest remaining uncertainties concern (1) characterization of open vegetation burning, which cannot be resolved without new field studies; (2) emission factors for small combustion devices, for which emissions testing is urgently needed; and (3) residential fuel consumption, which may require a reassessment of China's official statistics.

We found that the dual tag, his sub(6)-tag-maltose-binding protein (MBP), intended to facilitate purification and enhance proteins' solubility, disrupted such a pipeline, requiring additional screening and purification steps. Not all proteins rendered soluble by fusion to MBP remained soluble after its proteolytic removal, and in those cases where the protein remained soluble, standard purification protocols failed to remove completely the stoichiometric amount of his sub(6)-tagged MBP generated by proteolysis. Both liabilities were alleviated by construction of a vector that produces fusion proteins in which MBP, the his sub(6)-tag and the target protein are separated by highly specific protease cleavage sites in the configuration MBP-site-his sub(6)-site-protein. In vivo cleavage at the first site by co-expressed protease generated untagged MBP and his sub(6)-tagged target protein. Proteins not truly rendered soluble by transient association with MBP precipitated, and untagged MBP was easily separated from the his-tagged target protein by conventional protocols. The second protease cleavage site allowed removal of the his sub(6)-tag.

Prephenate dehydrogenases exist as either monofunctional or bifunctional enzymes. The bifunctional enzymes are diverse, since the prephenate dehydrogenase domain is associated with other enzymes, such as chorismate mutase and 3-phosphoskimate 1-carboxyvinyltransferase. We report the first crystal structure of a monofunctional prephenate dehydrogenase enzyme from the hyper-thermophile Aquifex aeolicus in complex with NAD super(+). This protein consists of two structural domains, a modified nucleotide-binding domain and a novel helical prephenate binding domain. The active site of prephenate dehydrogenase is formed at the domain interface and is shared between the subunits of the dimer. We infer from the structure that access to the active site is regulated via a gated mechanism, which is modulated by an ionic network involving a conserved arginine, Arg super(250). In addition, the crystal structure reveals for the first time the positions of a number of key catalytic residues and the identity of other active site residues that may participate in the reaction mechanism; these residues include Ser super(126) and Lys super(246) and the catalytic histidine, His super(147). Analysis of the structure further reveals that two secondary structure elements, beta 3 and beta 7, are missing in the prephenate dehydrogenase domain of the bifunctional chorismate mutase-prephenate dehydrogenase enzymes. This observation suggests that the two functional domains of chorismate mutase-prephenate dehydrogenase are interdependent and explains why these domains cannot be separated.

AN - 67906858; 16510295 AB - The receptor for advanced glycation endproducts (RAGE) is a multiligand receptor that binds a variety of structurally and functionally unrelated ligands, including advanced glycation endproducts (AGEs), amyloid fibrils, amphoterin, and members of the S100 family of proteins. The receptor has been implicated in the pathology of diabetes as well as in inflammatory processes and tumor cell metastasis. For the present study, the extracellular region of RAGE (exRAGE) was expressed as a soluble, C-terminal hexahistidine-tagged fusion protein in the periplasmic space of Escherichia coli. Proper processing and folding of the purified protein, predicted to contain three immunoglobulin-type domains, was supported by the results of electrospray mass spectroscopy and circular dichroism experiments. Sedimentation velocity experiments showed that exRAGE was primarily monomeric in solution. Binding to several RAGE ligands, including AGE-BSA, immunoglobulin light chain amyloid fibrils, and glycosaminoglycans, was demonstrated using pull-down, dot-blot, or enzyme-linked microplate assays. Using surface plasmon resonance, the interaction of exRAGE with AGE-BSA was shown to fit a two-site model, with KD values of 88 nM and 1.4 microM. The E. coli-derived exRAGE did not bind the advanced glycation endproduct Nepsilon-(carboxymethyl)lysine, as reported for the cellular receptor, and the possible role of RAGE glycosylation in recognition of this ligand is discussed. This new RAGE construct will facilitate detailed studies of RAGE-ligand interactions and provides a platform for preparation of site-directed mutants for future structure/function studies.

The Raman spectra were normalized and treated as vectors. The inner products among the Raman spectra are shown to correlate linearly with the ordered state of the crystals, suggesting that such an analysis of Raman spectra can, in principle, be used to rapidly estimate the ordering state of a mineral, and thus many other crystal properties related to the atomic order-disorder.

We have examined antimony speciation associated with the oxidation of stibnite (Sb (sub 2) S (sub 3) )-bearing waste rock in the eastern Tintina Gold Province (TGP). The TGP is a 150,000 km (super 2) area comprised of >15 gold belts and districts in western Yukon and east-central Alaska, in a region bounded by the Tintina and the Denali-Kaltag fault systems and underlain by Paleozoic metasedimentary rocks and mid-Cretaceous granitoids. Late-stage, fine- to coarse-grained stibnite, occurring in trace to minor amounts, is common within many of the ca. 90 Ma precious metal-bearing veins and stockworks in this region. Field measurements (pH, specific conductance, temperature), 0.45-mu m filtered water samples, and <63-mu m fraction stream sediments were collected at numerous sites within and downstream from waste rock at abandoned mine sites. These sites included three gold mines (e.g., Scrafford, McCarty, and Chatham Creek,) within the Fairbanks mining district in Alaska, and the Keno Hill Pb-Ag-Zn deposits in the Yukon. Water and sediment samples were analyzed for major, minor, and trace elements by ICP-mass spectrometry and for major anion compositions by ion chromatography. The stream waters ranged in pH from 5.5-8.5, with specific conductance from 17-694 S/cm, and can be described as Ca-HCO (sub 3) (super -) type waters. Our results show that the Sb concentrations in the <63-mu m stream sediments range broadly from 4 to 5700 ppm, and correlate well with As, Fe, and Al. Dissolved (<0.45 mu m) Sb concentrations were found to range from <0.3-634 mu g/L; however, the correlation with As, Fe, and/or Al is inconsistent. Antimony concentrations were an order of magnitude higher in both sediments and waters when draining exposed waste rock and tailings, compared to buried or re-vegetated waste-rock and tailings. Results of x-ray absorption spectroscopy analyses (XAFS and XANES) of the <63-mu m fraction stream sediments, and of secondary mineral weathering surfaces indicate that Sb in the stream sediments is in the form of Sb(V) and most likely adsorbed onto iron hydroxide, whereas secondary weathering phases appear to be a mixed Sb(III)/Sb(V) oxide. In contrast, As in stream sediments has been observed as both As(III) and As(V), thus indicating that Sb and As are not behaving in a chemically similar manner.

Spectra were obtained using both fluorescence and electron yields to obtain information representative of the bulk as well as the surface. Where appropriate, NEXAFS spectra have been interpreted by comparison with the densities of unfilled states and simulated spectra derived from ab initio calculations using primarily the FEFF8 code and to a lesser extent WIEN2k. Metal 2p and S 2p photoelectron spectra excited by monochromatised Al K (sub alpha ) X-rays were determined for each of the surfaces characterised by NEXAFS spectroscopy. The X-ray excited Cu LMM Auger spectrum was also determined for each copper-containing sulfide. FEFF8 calculations were able to simulate the experimental NEXAFS spectra quite well in most cases. For covellite and chalcocite, it was found that FEFF8 did not provide a good simulation of the Cu L (sub 3) -edge spectra, but WIEN2k simulations were in close agreement with the experimental spectra. Largely on the basis of these simulations, it was concluded that there was no convincing evidence for chalcopyrite to be represented as Cu (super II) Fe (super II) S (sub 2) , and no strong argument for some of the Cu in either bornite or covellite to be regarded as Cu(II). The ab initio calculations for chalcopyrite and bornite indicated that the density of Cu d-states immediately above the Fermi level was sufficient to account for the Cu L (sub 3) -edge absorption spectrum, however these incompletely filled Cu d-states should not be interpreted as indicating some Cu(II) in the sulfide structure. It was also concluded that the X-ray absorption spectra were quite consistent with the initial oxidation products on chalcopyrite and bornite surfaces being iron oxide species, and inconsistent with the concomitant formation of copper-oxygen species.

These films were deposited on highly conductive Si substrates at different temperatures (from 400 to 800DGC), using microwave plasma enhanced chemical vapor deposition with argon-rich Ar/CH4 gas mixtures and different relative amounts of hydrogen (0-20%). Scanning electron microscopy studies showed that all the films are dense and continuous. Results of cyclic voltammetry test revealed that when there was <2% of hydrogen in the plasma, the film obtained renders the surface electrochemically inactive, with very low leakage currents (4 X 10-7 A/cm2 at -5 V). In addition, in vivo tests of the UNCD-coated Si samples were performed by implanting them in the eyes of rabbits for 4-6 months within the eye physiological environment. According to all these results, it was concluded that UNCD is a promising candidate for use as the encapsulating coatings for implantable retinal microelectronic devices.

AN - 67951685; 16683586 AB - The disposal of basic sodium aluminate and acidic U(VI)-Cu(ll) wastes in the now-dry North and South 300 A Process Ponds atthe Hanford site resulted in a groundwater plume of U(VI). To gain insight into the geochemical processes that occurred during waste disposal and those affecting the current and future fate and transport of this uranium plume, the solid-phase speciation of uranium in a depth sequence of sediments from the base of the North Process Pond through the vadose zone to groundwater was investigated using standard chemical and mineralogical analyses, electron and X-ray microprobe measurements, and X-ray absorption fine structure spectroscopy. Near-surface sediments contained uranium coprecipitated with calcite, which formed due to overneutralization of the waste ponds with base (NaOH). At intermediate depths in the vadose zone, metatorbernite [Cu(UO2PO4)2 x 8H2O] precipitated, likely during pond operations. Uranium occurred predominantly sorbed onto phyllosilicates in the deeper vadose zone and groundwater; sorbed uranium was also an important component at intermediate depths. Since the calcite-bearing pond sediments have been removed in remediation efforts, uranium fate and transport will be controlled primarily by desorption of the sorbed uranium and dissolution of metatorbernite.

Such low compressional and shear wave velocities and high Poisson's ratio are also observed experimentally in post-perovskite silicate phase containing up to 40 mol% FeSiO (sub 3) endmember. The iron-rich post-perovskite silicate is stable at the pressure-temperature and chemical environment of the core-mantle boundary and can be formed by core-mantle reaction. Mantle dynamics may lead to further accumulation of this material into the ultralow-velocity patches that are observable by seismology.

An rpoS mutant was examined under steady-state conditions with acetate as an electron donor and fumarate as an electron acceptor and with additional transcriptional profiling using Fe(III) as an electron acceptor. Expression analysis revealed that RpoS acts as both a positive and negative regulator. Many of the RpoS-dependent genes determined play roles in energy metabolism, including the tricarboxylic acid cycle, signal transduction, transport, protein synthesis and degradation, and amino acid metabolism and transport. As expected, RpoS activated genes involved in oxidative stress resistance and adaptation to nutrient limitation. Transcription of the cytochrome c oxidase operon, necessary for G. sulfurreducens growth using oxygen as an electron acceptor, and expression of at least 13 c-type cytochromes, including one previously shown to participate in Fe(III) reduction (MacA), were RpoS dependent. Analysis of a subset of the rpoS mutant proteome indicated that 15 major protein species showed reproducible differences in abundance relative to those of the wild-type strain. Protein identification using mass spectrometry indicated that the expression of seven of these proteins correlated with the microarray data. Collectively, these results indicate that RpoS exerts global effects on G. sulfurreducens physiology and that RpoS is vital to G. sulfurreducens survival under conditions typically encountered in its native subsurface environments.

Here, we employ a novel combination of microenvironmental manipulation and microarray data filtration over narrowly delineated temporal data series to identify the morphogenesis component apart from the proliferation component, as pooled human microvascular-derived endothelial cells are induced to form capillary-like structures in vitro in a murine tumor-derived matrix. The 217 morphogenesis-specific genes identified using this subtractive transcriptomics approach are mostly independent of the angiogenic proteins currently used as therapeutic targets for aberrant angiogenesis. Quantitative real-time PCR was used to validate 20% of these transcripts. Immunofluorescent analysis of proliferating and tube-forming cells validates at the protein level the morphogenesis-specific expression pattern of 16 of the 217 gene products identified. The transcripts that are selectively up-regulated in tube-forming endothelial cells reveal a temporal expression pattern of genes primarily associated with intracellular trafficking, guided migration, cytoskeletal reorganization, cellular adhesion, and proliferation inhibition. These data show that a sequential up-regulation of genes that establish and maintain polarity occurs during migration and morphogenesis of in vitro human endothelial cells undergoing tubulogenesis; some of which may well be effective as novel antiangiogenic drug targets.

Considerable air pollution is caused by the manufacturing industries themselves and by the power plants, trucks, and ships that support them. We estimate that 10-40% of emissions of primary SO sub(2), NO sub(x), RSP, and VOC in the region are caused by export-related activities. Using the STEM-2K1 atmospheric transport model, we estimate that these emissions contribute 5-30% of the ambient concentrations of SO sub(2), NO sub(x), NO sub(z), and VOC in the region. One reason that the exported goods are cheap and therefore attractive to consumers in developed countries is that emission controls are lacking or of low performance. We estimate that state-of-the-art controls could be installed at an annualized cost of $0.3-3 billion, representing 0.3-3% of the value of the goods produced. We conclude that mitigation measures could be adopted without seriously affecting the prices of exported goods and would achieve considerable human health and other benefits in the form of reduced air pollutant concentrations in densely populated urban areas.

Within Staphylococcus aureus, virulence factor transcript synthesis is regulated by a number of two-component regulatory systems, the DNA binding protein SarA, and the SarA family of homologues. However, little is known about the factors that modulate mRNA stability or influence transcript degradation within the organism. As our entree to characterizing these processes, S. aureus GeneChips were used to simultaneously determine the mRNA half-lives of all transcripts produced during log-phase growth. It was found that the majority of log-phase transcripts (90%) have a short half-life (<5 min), whereas others are more stable, suggesting that cis- and/or trans-acting factors influence S. aureus mRNA stability. In support of this, it was found that two virulence factor transcripts, cna and spa, were stabilized in a sarA-dependent manner. These results were validated by complementation and real-time PCR and suggest that SarA may regulate target gene expression in a previously unrecognized manner by posttranscriptionally modulating mRNA turnover. Additionally, it was found that S. aureus produces a set of stable RNA molecules with no predicted open reading frame. Based on the importance of the S. aureus agr RNA molecule, RNAIII, and small stable RNA molecules within other pathogens, it is possible that these RNA molecules influence biological processes within the organism.

13866691 AB - Hemodynamic data on the roles of physiologically critical blood particulates are needed to better understand cardiovascular diseases. The blood flow patterns and particulate buildup were numerically simulated using the multiphase non-Newtonian theory of dense suspension hemodynamics in a realistic right coronary artery (RCA) having various cross sections. The local hemodynamic factors, such as wall shear stress (WSS), red blood cell (RBC) buildup, viscosity, and velocity, varied with the spatially nonuniform vessel structures and temporal cardiac cycles. The model generally predicted higher RBC buildup on the inside radius of curvature. A low WSS region was found in the high RBC buildup region, in particular, on the area of maximum curvature of a realistic human RCA. The complex recirculation patterns, the oscillatory flow with flow reversal, and vessel geometry resulted in RBC buildup due to the prolonged particulate residence time, specifically, at the end of the diastole cycle. The increase of the initial plasma viscosity caused the lower WSS. These predictions have significant implications for understanding the local hemodynamic phenomena that may contribute to the earliest stage of atherosclerosis, as clinically observed on the inside curvatures and torsion of coronary arteries.

These targets represent a heterogeneous group of proteins which for expression purposes were separated into cytoplasmic and helical membrane protein categories. Target selection was refined using a bioinformatic approach to generate a list of 50 experimental targets. A group consisting of forty-four cytoplasmic and signal-containing protein targets were amplified and cloned into multiple expression vectors. For this target category, we obtained 48% soluble expression products. In addition, we used a domain expression approach for six high molecular weight proteins predicted to contain membrane spanning helices to obtain soluble domain products. These results validate the utility of a bioinformatically driven high throughput approach to increase the number of soluble proteins or protein domains which can be used for multiple downstream applications.

200619210 AB - Progress in some fields has been shown to occur through a sequence of high-activity periods that often exhibit logistic growth patterns. Previously, this was demonstrated for local environmental issues during the U.S. Progressive Era through an analysis of environmental (aerial & water-borne) diseases. Later (1970s & 1980s), logistic growth trends in interest (articles & legislation) in national environmental concerns was demonstrated. Recently, environmental attention has included global issues resulting in several international environmental treaties that attempt to address the concerns. Logistic analysis is applied to the recent trends of interest in international environmental issues. This interest is measured at many levels: popular magazine articles, popular books, research-oriented books, & international treaties. There are indications that the elevated level of international environmental interest might have passed the midpoint, in the 1990s, of a 5-decade period. This recent period is compared with previously identified periods concerning local & national environmental issues. Possible reasons for the trends include the recent increasing rate & scope of technological development & the related, perhaps delayed social response. Potential future trends might indicate the relative rate of technological development & social resolution of its impacts. A possible leading indicator is the business & governance response to new technologies, like nanotechnology, which might be responsibly developed to mitigate previous environmental issues without introducing new unintended environmental consequences.

With its subgrid-scale distribution scheme, the PASS model couples surface meteorological observations with satellite remote sensing data to update root-zone available moisture and to simulate surface evapotranspiration rates at high resolution over extended areas. The PASS model is observationally driven, making use of extensive parameterizations of surface properties and processes. Heterogeneities in surface conditions are spatially resolved to an extent determined primarily by the satellite data pixel size. The purpose of modeling the spatial and interannual variability of water budget components at the regional scale is to evaluate the PASS model's ability to bridge a large grid cell of a climate model with its subgrid-scale variation. Modeled results indicate that annual total evapotranspiration at the WRW is about 66%-88% of annual precipitation--reasonable values for southeastern Kansas--and that it varies spatially and temporally. Seasonal distribution of precipitation plays an important role in evapotranspiration estimates. Comparison of modeled runoff with stream gauge measurements demonstrated close agreement and verified the accuracy of modeled evapotranspiration at the regional scale. In situ measurements of energy fluxes compare favorably with the modeled values for corresponding grid cells, and measured surface soil moisture corresponds with modeled root-zone available moisture in terms of temporal variability despite very heterogeneous surface conditions. With its ability to couple remote sensing data with surface meteorology data and its computational efficiency, PASS is easily used for modeling surface hydrological components over an extended region and in real time. Thus, it can fill a gap in evaluations of climate model output using limited field observations.

Various sources of information may be used to build a conceptual understanding of flow in the system, including drilling data, well tests, geophysical surveys, tracer tests, and spring gaging. These data were assembled to model flow numerically in Germany's Malm Formation, at a site where water disappears from the beds of ephemeral stream valleys, flows through conduit systems, and discharges to springs along surface water features. Modeling was performed by using a finite-difference approach, with drain networks, representing the conduit component of flow, laced throughout the porous medium along paths inferred on the basis of site data. This approach represents an improvement over other karst models that attempt to represent a conduit by a single, specialized model node at the spring location or by assigning a computationally problematic extremely high permeability to a zone.

To better understand the metabolic processes involved in the metal-reduction capability of this microbe, the proteins expressed by cells grown anaerobically with either fumarate or ferric citrate as electron acceptor were compared. Proteins were separated by 2-DE under denaturing or nondenaturing conditions, and proteins varying in abundance with a high level of statistical significance (p<0.0001) were identified by peptide mass analysis. Denaturing 2-DE revealed significant differences in the relative abundance of the membrane proteins OmpA and peptidoglycan-associated lipoprotein, several metabolic enzymes, and, in addition, superoxide dismutase and rubredoxin oxidoreductase. Nondenaturing 2-DE revealed elevated catalase in cells grown with ferric citrate. These results suggest that, in addition to adjustments in membrane transport and specific metabolic pathways in response to these two different electron acceptors, distinct differences exist in the oxidative environment within the cell when fumarate or soluble ferric citrate is provided as electron acceptor. Although an anaerobe, G. sulfurreducens appears to have alternate mechanisms for dealing with reactive oxygen species in response to increased intracellular soluble iron.

We estimate that total Hg emissions from all anthropogenic sources increased at an average annual rate of 2.9% during the period 1995-2003, reaching 696 ( plus or minus 307) t in 2003, with a speciation split of 395 t of Hg super(0), 230 t of Hg super(2+), and 70 t of Hg super(p). Nonferrous metals smelting and coal combustion continue to be the two leading mercury sources in China, as nonferrous metals production and coal consumption keep increasing. Nonferrous metals smelting and coal combustion together contributed similar to 80% of total Hg emissions during the past decade. Hg emissions from coal combustion increased from 202 t in 1995 to 257 t in 2003 at an average annual rate of 3.0%. Among all of the coal consumption sectors, the power sector is the leading one in Hg emissions growth, up by 5.9% annually. Hg emissions from nonferrous metals smelting increased from 230 t in 1995 to 321 t in 2003 at an average annual rate of 4.2%. Although Hg emissions related to gold smelting decreased since 1996, other nonferrous metals such as zinc, lead, and copper contributed significant Hg growth at annual rates of 8.5%, 13.0%, and 6.9%, respectively. At provincial level, the trends of Hg emissions show significant variation. The uncertainty level decreased from plus or minus 78% (95% confidence interval) in the estimate of total emissions in 1995, to plus or minus 44% in 2003. This is primarily attributed to the decreased emissions from those Hg sources with the largest uncertainty in both activity levels and emission factors, such as artisanal gold smelting, mercury mining, and battery/fluorescent lamp production.

DO - http://dx.doi.org/10.1021/es060406x ER - TY - JOUR T1 - US work on technical and economic aspects of electrolytic, thermochemical, and hybrid processes for hydrogen production at temperatures below 550 degree C AN - 20227455; 8106120 AB - Hydrogen demand is increasing, but there are few options for affordable hydrogen production free of greenhouse gas emissions. Nuclear power is one of the most promising options. Most research is focused on high-temperature electrolytic and thermochemical processes for nuclear-generated hydrogen, but it will be many years before very high temperature reactors become commercially available. For light water reactors or supercritical reactors, low-temperature water electrolysis is a currently available technology for hydrogen production. Higher efficiencies may be gained through thenno-electrochemical hydrogen production cycles, but there are only a limited number that have heat requirements consistent with the lower temperatures of light-water reactor technology. Indeed, active research is ongoing for only three such cycles in the USA. Reductions in electricity and system costs would be needed (or the imposition of a carbon tax) for low-temperature water electrolysis to compete with today's costs for steam methane reformation. The interactions between hydrogen and electricity markets and hydrogen and electricity producers are complex and will evolve as the markets evolve.

Interaction of cyanobacteria with aqueous gold(III)- chloride initially promoted the precipitation of nanoparticles of amorphous gold(I)-sulfide at the cell walls, and finally deposited metallic gold in the form of octahedral (111) platelets ( similar to 10 nm to 6 mm) near cell surfaces and in solutions. The XAS results confirm that the reduction mechanism of gold(III)- chloride to metallic gold by cyanobacteria involves the formation of an intermediate Au(I) species, gold(I)-sulfide.

The columns were operated above-ground at a contaminated field site to serve as physical models of an in situ bio-barrier for U and Tc removal from groundwater. Groundwater containing 4 mM U and 520 pM Tc was pumped through the columns for 20 months. One column received additions of ethanol to stimulate activity of indigenous microorganisms; a second column received no ethanol and served as a control. U(VI) and Tc(VII) removal was sustained for 20 months ( similar to 189 pore volumes) in the stimulated column under sulfate- and Fe(III)-reducing conditions. Less apparent microbial activity and only minor removal of U(VI) and Tc(VII) were observed in the control. Sequential sediment extractions and XANES spectra confirmed that U(IV) was present in the stimulated column, although U(IV) was also detected in the control; extremely low concentrations precluded detection of Tc(IV) in any sample. These results provide additional evidence that bio- immobilization may be effective for removing U and Tc from groundwater. However, long-term effectiveness of bio-immobilization may be limited by hydraulic conductivity reductions or depletion of bioavailable Fe(III).

The public protein sequence databases (e.g., NCBInr, UniProt) each contain millions of entries, and private databases add thousands more. Although much of the sequence information in these databases is redundant, each database uses distinct identifiers for the identical protein sequence and often contains unique annotation information. Users of one database obtain a database-specific sequence identifier that is often difficult to reconcile with the identifiers from a different database. When multiple databases are used for searches or the databases being searched are updated frequently, interpreting the protein identifications and associated annotations can be problematic. We have developed a database of unique protein sequence identifiers called Sequence Globally Unique Identifiers (SEGUID) derived from primary protein sequences. These identifiers serve as a common link between multiple sequence databases and are resilient to annotation changes in either public or private databases throughout the lifetime of a given protein sequence. The SEGUID Database can be downloaded (http://bioinformatics.anl.gov/SEGUID/) or easily generated at any site with access to primary protein sequence databases. Since SEGUIDs are stable, predictions based on the primary sequence information (e.g., pI, M sub(r)) can be calculated just once; we have generated approximately 500 different calculations for more than 2.5 million sequences. SEGUIDs are used to integrate MS and 2-DE data with bioinformatics information and provide the opportunity to search multiple protein sequence databases, thereby providing a higher probability of finding the most valid protein identifications.

Structures with low absorption contrast have been visualized using in-line phase contrast imaging. The experiments have been performed at the Advanced Photon Source, a third generation source of synchrotron radiation. The source provides highly coherent X-ray radiation with high photon flux (>10 super(14) photons/s) at high photon energies (5-70 keV). Thick gerbil cochlear slices have been imaged and were compared with those obtained by light microscopy. Furthermore, intact gerbil cochleae have been imaged to identify the soft tissue structures involved in the hearing process. The present experimental approach was essential for visualizing the inner ear structures involved in the hearing process in an intact cochlea. Microsc. Res. Tech., 2006.

We present the first prediction, to the authors knowledge, of particulate buildup on the inside curvature using the multiphase theory of dense suspension hemodynamics. In this study, the particulates are red blood cells (RBCs). The location of RBC buildup on the inside curvature correlates with lower wall shear stress (WSS) relative to the outside curvature. These predictions provide insight into how blood- borne particulates interact with artery walls and hence, have relevance for understanding atherogenesis since clinical observations show that atherosclerotic plaques generally form on the inside curvatures of arteries. The buildup of RBCs on the inside curvature is driven by the secondary flow and higher residence times. The higher viscosity in the central portion of the curved vessel tends to block their flow, causing them to migrate preferentially through the boundary layer. The reason for this is the nearly neutrally buoyant nature of the dense two-phase hemodynamic flow. The two-phase non-Newtonian viscosity model predicts greater shear thinning than the single-phase non- Newtonian model. Consequently, the secondary flow induced in the curvature is weaker. The waveforms for computed hemodynamic parameters, such as hematocrit, WSS, and viscosity, follow the prescribed inlet velocity waveforms. The lower oscillatory WSS produced on the inside curvature has implications for understanding thickening of the intimal layer.

Phages are biotinylated efficiently ([ge]50 %) when grown in E. coli cells coexpressing BirA, and such viral particles can be immobilized on a streptavidin-coated support and released by protease cleavage within the combinatorial peptide. We have used this library to map the specificity of human Factor Xa and a neuropeptidase, neurolysin (EC3.4.24.16). Validation by analysis of isolated peptide substrates has revealed that neurolysin recognizes the motif hydrophobic-X-Pro-Arg-hydrophobic, where Arg-hydrophobic is the scissile bond.

Here, we show, through meta-analysis techniques, that these experiments collectively exhibited a 5.6% increase in soil C over 2-9 years, at a median rate of 19 g C m super(-2) yr super(-1). We also measured C accrual in deciduous forest and grassland soils, at rates exceeding 40 g C m super(-2) yr super(-1) for 5-8 years, because both systems responded to CO sub(2) enrichment with large increases in root production. Even though native C stocks were relatively large, over half of the accrued C at both sites was incorporated into microaggregates, which protect C and increase its longevity. Our data, in combination with the meta-analysis, demonstrate the potential for mineral soils in diverse temperate ecosystems to store additional C in response to CO sub(2) enrichment.

To more fully constrain the utility of this approach using a previously described gel-pad microarray format, artificial neural networks (NNs) were trained to recognize noisy or low-quality data, as might derive from nonspecific fluorescence, poor hybridization, or compromised data collection. The NNs were trained to classify dissociation profiles (melts) into groups based on selected characteristics (e.g., initial signal intensity, area under the curve) using a data set of 21,044 profiles derived from 186 probes hybridized to a study set of RNA extracted from 32 microbes common to the human oral cavity. Three melt profile groups were identified: one group consisted mostly of ideal melt profiles; another group consisted mostly of poor melt profiles; and, the remainder were difficult to classify. Screening of melting profiles of perfect-match hybrids revealed inconsistencies in the form of melting profiles even for identical probes on the same microarray hybridized to same target rRNA. Approximately 18% of perfect-match duplex types were correctly classified as poor. Experimental variability and deviation from ideal melt behavior were shown to be attributable primarily to a method of local background subtraction that was very sensitive to displacement of the grid frames used for image capture (both determined by the image analysis system) and duplexes with low binding constants. Additional results showed that long RNA fragments limit the discriminating power among duplex types.

Often these proteins have no associated biochemical or cellular functions. The SG success has resulted in an accelerated deposition of novel structures. In some cases the structural bioinformatics analysis applied to these novel structures has provided specific functional assignment. However, this approach has also uncovered limitations in the functional analysis of uncharacterized proteins using traditional sequence and backbone structure methodologies. A novel method, named pvSOAR (pocket and void Surface of Amino Acid Residues), of comparing the protein surfaces of geometrically defined pockets and voids was developed. pvSOAR was able to detect previously unrecognized and novel functional relationships between surface features of proteins. In this study, pvSOAR is applied to several structural genomics proteins. We examined the surfaces of YecM, BioH, and RpiB from Escherichia coli as well as the CBS domains from inosine-5'-monosphate dehydrogenase from Streptococcus pyogenes, conserved hypothetical protein Ta549 from Thermoplasm acidophilum, and CBS domain protein mt1622 from Methanobacterium thermoautotrophicum with the goal to infer information about their biochemical function.

These enzymes utilize the ubiquitous methyl donor SAM as a cofactor to methylate proteins, small molecules, lipids, and nucleic acids. Here we present the crystal structure of PH1915 from Pyrococcus horikoshii OT3, a predicted SAM-dependent methyltransferase. This protein belongs to the Cluster of Orthologous Group 1092, and the presented crystal structure is the first representative structure of this protein family. Based on sequence and 3D structure analysis, we have made valuable functional insights that will facilitate further studies for characterizing this group of proteins. Specifically, we propose that PH1915 and its orthologs are rRNA- or tRNA-specific methyltransferases.

Proline biosynthesis can occur via two pathways, one from glutamate and the other from arginine. In both pathways, the last step of biosynthesis, the conversion of Delta super(1)-pyrroline-5-carboxylate (P5C) to l-proline, is catalyzed by Delta super(1)-pyrroline-5-carboxylate reductase (P5CR) using NAD(P)H as a cofactor. We have determined the first crystal structure of P5CR from two human pathogens, Neisseria meningitides and Streptococcus pyogenes, at 2.0A and 2.15A resolution, respectively. The catalytic unit of P5CR is a dimer composed of two domains, but the biological unit seems to be species-specific. The N-terminal domain of P5CR is an alpha / beta / alpha sandwich, a Rossmann fold. The C-terminal dimerization domain is rich in alpha -helices and shows domain swapping. Comparison of the native structure of P5CR to structures complexed with l-proline and NADP super(+) in two quite different primary sequence backgrounds provides unique information about key functional features: the active site and the catalytic mechanism. The inhibitory l-proline has been observed in the crystal structure.

The Q super(-) sub(A) and Q super(-) sub(B) radical species in Fe-removed/Zn-replaced protonated RCs substituted with deuterated quinones are distinguishable with pulsed D-band (130 GHz) EPR and provide native probes of both the low-temperature Q super(-) sub(A)Q sub(B) arrow right Q sub(A)Q sub(B) event and the structure of trapped conformational substates. We report here the first spectroscopic evidence that cryogenically trapped, light-induced changes enable low-temperature Q super(-) sub(A)Q sub(b) arrow right Q sub(a)Q super(-) sub(b) electron transfer in the B. viridis RC and the first observation of an inactive, trapped P super(+)Q super(-) sub(B) state in both R. sphaeroides and B. viridis RCs that does not recombine at 20 K. The high resolution and orientational selectivity of HF electron-nuclear double resonance (ENDOR) allows us to directly probe protein environments around Q super(-) sub(B) for distinct P super(+)Q super(-) sub(B) kinetic RC states by spectrally selecting specific nuclei in isotopically labeled samples. No structural differences in the protein structure near Q super(-) sub(B) or reorientation (within 5 degree ) of Q super(-) sub(B) was observed with HF ENDOR spectra of two states of P super(+)Q super(-) sub(B): "active" and "inactive" states with regards to low-temperature electron transfer. These results reveal a remarkably enforced local protein environment for Q sub(B) in its reduced semiquinone state and suggest that the conformational change that controls reactivity resides beyond the Q sub(B) local environment.

Of particular significance is the circulation's effect on the dispersion of pollutants such as ozone and aerosols produced in and around the city. To investigate these effects, the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) was used to perform numerical simulations for two lake-breeze events-one in July 1999 and another in July 2002. The model runs were verified with data from several locations around the Chicago area. The simulated breeze circulation decreased the rate of increase in air temperature while penetrating roughly 12 km inland and lasting about 8 h, in reasonable agreement with observations. Furthermore, the inland penetration distance was related to the strength of the maximum vertical velocity within the front. Calculations of trajectories and transport of particles showed that the breeze tended to transport particles trapped within it to the north when release occurred before the circulation came ashore, whereas particles released at the time of the breeze's landfall or afterward moved more northeasterly, in the direction of the prevailing wind. Thirty-four percent of all released particles were trapped by the circulation and raised to a height of at least 300 m, and 20% of the particles remained in the lowest 100 m above the surface. In addition, sensitivity tests showed little change in the modeled breeze when measured surface temperatures for Lake Michigan were used as initial conditions and boundary conditions in the place of surface skin temperature (as derived by the National Centers for Environmental Prediction). Raising the lake temperatures significantly in the simulation yielded a more elongated vertical circulation and a briefer lake-breeze event that did not reach as far inland.

The USDA requires a detection process that is easy to implement and use, cost effective, and very sensitive. Currently specially trained beagles, their handlers, human inspectors, and X-ray machines accomplish the bulk of this work. In an attempt to augment the beagle brigade, Argonne National Laboratory is developing electronic nose devices by detecting and identifying characteristic or associated odors to address the agricultural threats. The electronic nose is a device that uses an array of chemical sensors to mimic the way a human nose samples and processes odors. Each sensor produces independent responses for a given odor that are then converted from chemical signals to electrical ones with a connected data processor. The collection of all the sensors responses produces a `pattern" for a given odor. The data processing system compares the pattern of an unknown odor with a library of patterns previously databased. If a pattern matches one in the library, the odor is identified. The sensitivity of most electronic noses is in the low ppm ( mu L/L) range and not sufficient to detect contraband in the environment. In order to improve the sensitivity, methods for improving the sampling of contraband were explored and will be presented.

Because of its toxicity, mercury must be removed from agent prior to incineration or be scrubbed from incineration exhaust to prevent release into the atmosphere. Understanding mercury/agent interactions is critical if either atmospheric or aqueous treatment processes are used. We investigate and compare the state of mercury in water to that in thiodiglycol, a mustard simulant, as co-contaminants are introduced. The effects of sodium hypochlorite and sodium hydroxide, common neutralization chemicals, on mercury in water and simulant with and without co-contaminants present are examined using X-ray absorption fine spectroscopy (XAFS).

In these areas, the limited fresh water resources and the rising demands due to increasing population is leading to political, economical, and social instabilities. We present an integrated methodology to identify alternative renewable water resources; the advocated methodology heavily relies on satellite-based global data sets that are readily available world-wide. We adopt a catchment-based continuously distributed hydrologic model to quantify the spatial and temporal distribution of surface runoff and potential groundwater recharge. The model includes two modules: (1) automated data processing module, and (2) catchment-based distributed surface runoff module. The data processing module extracts precipitation, air temperature, surface temperature, soil moisture, solar radiation, and normalized vegetation difference index (NDVI) values from a suite of satellite data (TRMM, SSM/I, AVHRR, METEOSAT). This is enabled through a series of operations including assimilation, compilation, calibration, georeferencing, stacking, geographical sub-setting, and threshold filtering. The surface runoff module provides a continuous simulation of the overland flow, channel flow, transmission loss, evaporation on bare soils and evapo-transpiration (ET) on vegetated canopy, and potential recharge to shallow groundwater system. The developed procedures were applied to the Eastern Desert of Egypt (220,000 km2), an area where adequate hydrologic monitoring systems are absent. The following series of datasets were generated as inputs to our model: 1) 3-hourly precipitation data (1998-2005--TRMM), (2) 4-hourly precipitation (1987-2005--SSM/I), (3) NDVI Maps (1987-2005--AVHRR), (4) Soil Moisture, (5) Land Surface Temperature Maps (1987-2005--AVHRR), and (6) Lithologic Maps. The model automatically integrates these datasets to provide temporal and spatial estimates for runoff and recharge in the investigated basins ( approximately 6000) of the Eastern Desert. Similar applications for understanding the hydrology and dynamics of water systems in arid regions and water availability in these areas are clear.

The results show that Zn is homogeneously distributed through most of the ferromagnesian minerals, commonly following Fe, for which it probably substitutes. The distribution of Cu is more complex, and includes Cu-rich patches of as yet unknown mineralogy that are widespread in all minerals. Median Cu and Zn contents for magmatic minerals, estimated excluding the Cu-rich patches, are lower and higher, respectively, than those of volcanic rocks in the area. Copper must thus have behaved incompatibly, whereas Zn behaved compatibly during magmatic crystallization. Decreasing contents of Cu from core to rim were observed in biotite fom the volcanic rocks, but Cu and Zn zoning is absent in ferromagnesian minerals in the intrusive rocks. Altered rims on biotite in the intrusive rocks are enriched in Cu and locally in Zn and may reflect post-crystallization migration of a late magmatic vapour phase.

In this study, we measured Np adsorption onto a common gram-positive soil bacterium, Bacillus subtilis. We performed batch adsorption experiments with Np(V) solutions as a function of pH, from 2.5 to 8, as a function of total Np concentration from 1.29 X 10 (super -5) M to 2.57 X 10 (super -4) M, and as a function of ionic strength from 0.001 to 0.5 M NaClO (sub 4) . Under most pH conditions, Np adsorption is reversible and exhibits an inverse relationship with ionic strength, with adsorption increasing with increasing pH. At low pH in the 0.1 M ionic strength systems, we observed irreversible adsorption, which is consistent with reduction of Np(V) to Np(IV). We model the adsorption reaction using a nonelectrostatic surface complexation approach to yield ionic strength dependent NpO (sub 2) (super +) -bacterial surface stability constants. The data require two bacterial surface complexation reactions to account for the observed adsorption behavior: R-L (sub 1) (super -) + NpO (sub 2) (super +) R-L (sub 1) -NpO (sub 2) (super 0) and R-L (sub 2) (super -) + NpO (sub 2) (super +) R-L (sub 2) -NpO (sub 2) (super 0) , where R represents the bacterium to which each functional group is attached, and L (sub 1) and L (sub 2) represent the first and second of four discrete site types on the bacterial surface. Stability constants (log K values) for the L (sub 1) and L (sub 2) reactions in the 0.001 M system are 2.3+ or -0.3 and 2.3+ or -0.2, and in the 0.1 M system the values are 1.7+ or -0.2 and 1.6+ or -0.2, respectively. The calculated neptunyl-bacterial surface stability constants are not consistent with values predicted using the linear free energy correlation approach from Fein et al. (2001), suggesting that possible unfavorable steric interactions and the low charge of NpO (sub 2) (super +) affects Np-bacterial adsorption.

However, the term coprecipitation is loosely used in a phenomenological sense, and the mechanism of coprecipitation is poorly understood. To understand coprecipitation mechanism and develop quantitative models, we studied Pb (super 2+) and Fe (super 3+) coprecipitation by measuring the sorption edges at ambient temperature, pressure, and various Fe:Pb ratios, with High-resolution Transmission and Analytical Electron Microscopy (HR TEM-AEM), Extended X-ray Absorption Fine Structure (EXAFS) analysis, and geochemical modeling of solid solution and surface complex formation. The coprecipitates have an X-ray diffraction pattern typical of 2-line ferrihydrite. HRTEM shows that the freshly formed coprecipitates are single crystalline spheres with approximately 5 nanometer diameter and with clear lattice images showing no massive defects. Coprecipitation of Pb (super 2+) with ferrihydrite begins at about pH 4, and the sorption edges are located at a lower pH than published sorption edges from adsorption experiments under otherwise similar experimental conditions. In other words, coprecipitation removes the same amount of Pb (super 2+) with about half the amount of the carrier constituent Fe (super 3+) , clearly indicating that coprecipitation is more efficient than adsorption in removing Pb (super 2+) from aqueous solutions. HRTEM-AEM analysis confirms that Pb (super 2+) is associated with the ferrihydrite. Both HRTEM-AEM and EXAFS did not detect any Pb-concentrated phases in the coprecipitates cluster or at single crystal edges. Hence, occlusion and surface precipitation are excluded as major coprecipitation mechanisms. EXAFS shows distinct spectrum patterns different from those of adsorbed Pb (super 2+) under otherwise similar conditions, indicating different Pb (super 2+) incorporation patterns. After ageing for one year, Pb (super 2+) -ferrihydrite with a Pb/Pb+Fe ratio of 10% transformed into a mixture of lepidocrocite, goethite, and 2-line ferrihydrite. In contrast, ferrihydrite with no co-precipitated Pb (super 2+) transformed to goethite needles, and ferrihydrite with 7% Zn/Fe+Zn remained as spherical ferrihydrite. Thus, co-precipitated divalent metals altered the rate of ferrihydrite transformation to more ordered iron oxyhydroxides.

It is commonly observed that apparent steady-state reaction rates of silicate minerals in aquifers decrease with the duration of the reaction. This observation has been attributed to various factors, including: increasing total surface area, decreasing reactive surface area, accumulation of leached layers and surface precipitates and/or organic adsorbates, and approach of the system to thermodynamic equilibrium (decreasing reaction affinity). Many of these factors are now accessible to direct experimental observation at the molecular scale by using synchrotron x-ray scattering methods on single crystals with well defined surface areas and controlled reaction conditions (solution composition, temperature, flow rate). For example, X-ray scattering studies of orthoclase dissolution involving gem-quality single-crystal surfaces under acidic and basic, far-from-equilibrium conditions, have shown that layer-by-layer dissolution rates on different crystal faces can be measured precisely, dissolution is essentially congruent, and the commonly described "leached layer" consists of secondary Si- and/or Al-rich oxyhydroxide precipitates (Teng et al., GCA 65, 2001; Fenter et al., GCA 67, 2003). Growth rates, structures, and epitaxial relationships of secondary precipitates can also be measured precisely (e.g., Chiarello et al., GCA 61, 1997), as can those of adsorbed organic layers (e.g., Fenter and Sturchio, GCA 63, 1999). Recent results have begun to elucidate the structures of water and the electrical double-layer at the mineral-water interface (Fenter and Sturchio, Prog. Surf. Sci. 77, 2004; Zhang et al., Langmuir 20, 2004); these advances may lead to more accurate molecular-scale models of mineral-water interfacial reaction kinetics. Enhanced understanding of molecular-scale reaction mechanisms and kinetics at the mineral-water interface will ultimately be transferable to larger-scale (spatial and temporal) aquifer systems, reducing the prevailing uncertainties and enabling the formulation of more realistic aquifer models.

Two different techniques, X-ray emission spectroscopy (XES) and synchrotron Moessbauer spectroscopy (SMS), were used by different groups to detect spin state changes under pressure. In this study, we apply both techniques to the same sample in order to derive additional information on the pressure induced spin state changes in Al-bearing perovskite. XES spectra of an Al-bearing perovskite (Mg (sub 0.87) Fe (sub 0.09) )(Si (sub 0.94) Al (sub 0.10) )O (sub 3) from 21 to 100 GPa suggest that iron experiences a gradual loss of magnetic moment with increasing pressure (Li et al. 2004). At 100 GPa, the residual magnetic moment is about 60% of the initial value at 1 bar. According to conventional Moessbauer data, our sample contains 53% Fe (super 3+) and 47% Fe (super 2+) , each taking one crystallographic site. Assuming that valence states and sites do not change with pressure, a number of scenarios can account for the XES observations, including 1) Fe (super 2+) changes into the low-spin state, while Fe (super 3+) stays in the high-spin state, 2) both Fe (super 2+) and Fe (super 3+) change into intermediate-spin states, and 3) Fe (super 2+) stays in the high-spin state, while Fe (super 3+) changes into the low-spin state. From XES data alone, these alternative scenarios cannot be readily resolved. Our new SMS data are in excellent agreement with the results of conventional Moessbauer measurements at ambient conditions. The high pressure SMS results show that the difference in the isomer shifts of Fe (super 2+) and Fe (super 3+) decreases with increasing pressure. Considering the expected changes in IS associated with spin changes, scenario 3) can be excluded. The likely scenarios that can explain both the XES and SMS data are that Fe (super 2+) changes from the high-spin state to the low-spin state or that both Fe (super 2+) and Fe (super 3+) change into intermediate-spin states by 100 GPa. Thus, the combination of these two complimentary techniques provides new insights into the spin state of iron in lower mantle perovskite.

Using crystal field theory and an extended Bragg-Williams mean-field theory, we predict an extended high-spin to low-spin crossover region along the geotherm for Fe-dilute systems depending on crystal-field splitting, pairing energy, and cooperative interactions. In particular, spin transitions in ferromagnesium silicate perovskite and ferropericlase, the dominant lower mantle components, should occur in a wide temperature-pressure range. We also derive a gradual volume change associated with such transitions in the lower mantle. The gradual density changes and the wide spin crossover regions seem incompatible with lower mantle stratification resulting from a spin transition.

The resulting stratigraphic package may include materials with a wide distribution of permeabilities, along with such variability that hole-to-hole correlations may be difficult to determine. Wellhead protection (WHP) programs rely on various approaches for delineating zones of protection. One method involves detailed numerical groundwater flow modeling of an area surrounding a well or wellfield, including justifiable boundary conditions, accurately estimated input parameter values, and a suitable subsurface model. But for WHP modeling in glaciated terrain, the complicated stratigraphy may preclude the creation of a valid subsurface model. Geostatistical analysis of high-quality and/or high-density drilling data from the vicinity of the wellfield may provide the necessary means for stochastic modeling of stratigraphy and groundwater flow. This presentation is focused on a case study in central Minnesota, where a wellfield is located in an area where several ice lobes converged to create a highly heterogeneous hydrogeologic framework. Two methods under investigation are indicator kriging and transition probability geostatistics. The results describe the 3-D correlation structure of the aquifer and aquitard units, and multiple, equally probable realizations provide a probabilistic WHP model.

Initially, a series of site-specific investigations were compiled, a hierarchical analysis that characterized the hydrologic system of the watershed was performed, conceptual models for the hydrologic system were developed, and uncertainties about the hydrologic system and likelihood of possible contaminant migration pathways were identified. This subsequent site-specific study focused on two tailings sites, Prospector Square and Silver Maple Claims, which are environmentally significant to the watershed and located in the middle of the Park City community. Four steps with significant results were then accomplished: 1) A steady-state numerical model was calibrated to show that the Park City Formation hydrologic input into the alluvial system is significant and affects the remediation process; 2) Sensitivity analysis was conducted to show variations of alluvial hydraulic conductivity for all model layers, variation of Silver Creek stream-bed conductance along the Prospector Square and Silver Maple Claims, variation of the Pace-Homer irrigation ditch-bed conductance, variation of the engineered Prospector drain pipe conductance, and variation of recharge rates for the upper model layer; 3) Potential contaminant pathways in the hydrologic system were evaluated using particle transport functions; and 4) The impact of remedial measures on the contaminant pathways was evaluated including: lining of Silver Creek in the Prospector Square area; lining of the Pace-Homer ditch; and discontinuing the engineered Prospector Square drain function. The results of this study, to be used to aid decision-makers in selecting and implementing multiple remedial actions, demonstrate the importance of evaluating engineering solutions simultaneously with a systems approach.

AN - 68611982; 16178814 AB - Selections from phage-displayed combinatorial peptide libraries are an effective strategy for identifying peptide ligands to target proteins. Existing protocols for constructing phage-displayed libraries utilize either ligation into double-stranded phage DNA or Kunkel mutagenesis with single-stranded phagemid DNA. Although the Kunkel approach rapidly provides library sizes of up to 10(11), as many as 20% of the phagemids may be non-recombinant. With several modifications to current Kunkel protocols, we have generated peptide libraries with sizes of up to 10(11) clones and recombination frequencies approaching 100%. The production of phage libraries, as opposed to phagemid libraries, simplifies selection experiments by eliminating the need for helper phage. Our approach relies upon the presence of an amber stop codon in the coding region of gene III of bacteriophage M13. Oligonucleotides containing randomized stretches of DNA are annealed to the phage genome such that the randomized region forms a heteroduplex with the stop codon. The oligonucleotide is then enzymatically extended to generate covalently-closed, circular DNA, which is electroporated into a non-suppressor strain of Escherichia coli. If the amber stop codon is present in the DNA molecule, protein III is not synthesized and the phage cannot propagate itself. This method is customizable for the display of either random or focused peptide libraries. To date, we have constructed 22 different libraries ranging from 8-20 amino acids in length, utilizing complete or reduced codon sets.

The resulting film containing 2.4 wt.% platinum was then reduced under H (sub 2) at 150 degrees C for 2-4 h, turning black upon reduction. XRD shows development of Pt(0) by the appearance of crystalline peaks upon reduction. A lineshape analysis using the Scherrer equation of the (220) peak shows Pt(0) particles from 3.8 nm to 7.5 nm depending upon processing conditions. These values are confirmed by TEM, and a high dispersion of the metal throughout the matrix is evident. XRD and TGA confirm that PEO is stable to the processing conditions. In situ small-angle X-ray scattering measurements of the reduction process were also performed. Under an inert, non-reducing atmosphere, the shape of the scattering curve does not change as the temperature is raised from 30 degrees C to 150 degrees C. Analysis of the scattering curves using the general unified fit (GUF) equation yields one Rg value of 80 A from 30 to 150 degrees C under He, which is assumed to arise from the overall film morphology. Under H (sub 2) , however, the shape of the scattering curves visually changes between 100 and 120 degrees C. Two structural levels are needed to fit these curves at moderate temperatures in the GUF equation, with two subsequent Rg values. One of these Rg values corresponds to the film morphology (Rg = 80-90 A), while the other has an Rg = 18-19 A with a corresponding diameter of 4.8-5.1 nm.

Mineralogy affects microbial metabolism and ecology in a system; microbes, in turn, can affect the system's mineralogy. Increasingly, synchrotron-based X-ray experiments are in routine use for determining an element's valence state and coordination chemistry, as well as for examining the role of microbes in metal transformations.

Development of methods for the in vivo substitution of methionine by selenomethionine (SeMet) has revolutionized the process for determination of structures of soluble proteins in recent years. Herein, we report methods for biosynthetic incorporation of SeMet into induced intracytoplasmic membrane proteins of two species of the Rhodobacter genus of purple non-sulfur photosynthetic bacteria. Amino acid analysis of a membrane protein complex that was purified to homogeneity determined that the extent of SeMet incorporation was extensive and approached quantitative replacement. Diffraction-quality crystals were obtained from SeMet-labeled membrane proteins purified from 2 l of culture. These methods augment the potential utility of photosynthetic bacteria and their inducible membrane systems for the production of foreign membrane proteins for structure determination.

The sludge simulants are representative of materials created as a result of the operation of the Bismuth Phosphate (sludges B and M), PUREX (sludge P), and REDOX (sludge R) processes at Hanford. Leaching with oxidants under alkaline conditions has been proposed as a means of reducing the chromium content of actual sludge samples prior to their vitrification. With identical amounts of plutonium deposited on each sludge sample, the percentage of radiotracer Pu leached from the sludges increased in the order P=R>B. This order is the reverse of the chromium content of the sludges. The percentage of plutonium leached was independent of its initial oxidation state. The reverse trends of chromium content and plutonium leaching can be understood in terms of Pu re-adsorption onto the MnO sub(2) generated as Cr(III) (and other substrates) are oxidized by permanganate/manganate. The effect of chelating agents that are known to be present in tank wastes (EDTA, gluconate, glycolate, oxalate, and citrate) on KMnO sub(4) reduction/MnO sub(2) production and redeposition of plutonium was also studied and found to have varied effects on the process of oxidative dissolution/Pu redeposition. Overall, it appears that the MnO sub(2) produced as a byproduct of oxidation helps to control Pu concentrations in the leachate phase. Oxidation of Pu to the hexavalent state without concomitant production of MnO sub(2) leads to greater plutonium content in the leachate. The results are discussed, emphasizing the potential impact of oxidative leaching on plutonium mobilization from actual tank-waste sludge.

To gain insight into the geochemical processes that occurred during waste disposal and those affecting the current and future fate and transport of this uranium plume, the solid-phase speciation of uranium in a depth sequence of sediments from the base of the North Process Pond through the vadose zone to groundwater was investigated using standard chemical and mineralogical analyses, electron and X-ray microprobe measurements, and X-ray absorption fine structure spectroscopy. Near-surface sediments contained uranium coprecipitated with calcite, which formed due to overneutralization of the waste ponds with base (NaOH). At intermediate depths in the vadose zone, metatorbernite [Cu(UO sub(2)PO sub(4)) sub(2); 8H sub(2)O] precipitated, likely during pond operations. Uranium occurred predominantly sorbed onto phyllosilicates in the deeper vadose zone and groundwater; sorbed uranium was also an important component at intermediate depths. Since the calcite-bearing pond sediments have been removed in remediation efforts, uranium fate and transport will be controlled primarily by desorption of the sorbed uranium and dissolution of metatorbernite.

AN - 68470849; 16090992 AB - We study velocity statistics of electrostatically driven granular gases. For two different experiments, (i) nonmagnetic particles in a viscous fluid and (ii) magnetic particles in air, the velocity distribution is non-Maxwellian, and its high-energy tail is exponential, P(upsilon) approximately exp(-/upsilon/). This behavior is consistent with the kinetic theory of driven dissipative particles. For particles immersed in a fluid, viscous damping is responsible for the exponential tail, while for magnetic particles, long-range interactions cause the exponential tail. We conclude that velocity statistics of dissipative gases are sensitive to the fluid environment and to the form of the particle interaction.

Beryllium-7 (7Be) is produced in the upper troposphere and lower stratosphere by the interaction of cosmogenic particles with atmospheric nitrogen and oxygen. 7Be has a 53.29-day half-life (478 keV) and is known to attach to fine particles in the atmosphere once it is formed. It has been suggested that O3 from aloft can be transported into rural and urban regions during stratospheric-tropospheric folding events leading to increased background levels of O3 at the surface. 7Be can be used as a tracer of upper atmospheric air parcels and the O3 associated with them. Aerosol samples with a 2.5-um cutoff were collected during 12-hr cycles (day/night) for a 30-day period at Deer Park, TX, near Houston, in August-September of 2000, and at Waddell, AZ, near Phoenix, in June-July of 2001. A comparison of 7Be levels with 12-hr O3 averages and maxima shows little correlation. Comparison of nighttime and daytime O3 levels indicate that during the day, when mixing is anticipated to be higher, the correlation of 7Be with O3 in Houston is approximately twice that observed at night. This is consistent with mixing and with the anticipated loss of O3 by reaction with nitric oxide (NO) and dry deposition. At best, 30% of the O3 variance can be explained by the correlation with 7Be for Houston, less than that for Phoenix where no significant correlation was seen. This result is consistent with the intercept values obtained for 7Be correlations with either O3 24-hr averages or O3 12-hr maxima and is also in the range of the low O3 levels (25 ppb) observed at Deer Park during a tropical storm event where the O3 is attributable primarily to background air masses. That is, maximum background O3 level contributions from stratospheric sources aloft are estimated to be in the range of 15-30 ppb in the Houston, TX, and Phoenix, AZ, area, and levels above these are because of local tropospheric photochemical production.

The primary concern has been the potential health effects resulting from exposure to residual radioactive materials to be released for unrestricted use. These debates have intensified in the last decade as many regulated facilities are seeking viable management decisions on the disposition of the large amounts of materials potentially containing very low levels of residual radioactivity. Such facilities include the nuclear weapons complex sites managed by the U.S. Department of Energy, commercial power plants licensed by the U.S. Nuclear Regulatory Commission (NRC), and other materials licensees regulated by the NRC or the Agreement States. Other facilities that generate radioactive material containing naturally occurring radioactive materials (NORM) or technologically enhanced NORM (TENORM) are also seeking to dispose of similar materials that may be radioactively contaminated. In contrast to the facilities operated by the DOE and the nuclear power plants licensed by the U.S. Nuclear Regulatory Commission, NORM and TENORM facilities are regulated by the individual states. Current federal laws and regulated do not specify criteria for releasing these materials that may contain residual radioactivity of either man-made or natural origin from regulatory controls. In fact, the current regulatory scheme offers no explicit provision to permit materials being released as "non-radioactive," including those that are essentially free of contamination. The only method used to date with limited success has been case-by-case evaluation and approval. In addition, there is a poorly defined and inconsistent regulatory framework for regulating NORM and TENORM. Some years ago, the International Atomic Energy Agency introduced the concept of clearance, that is, controlling releases of any such materials within the regulatory domain. This paper aims to clarify clearance as an important disposition option for solid materials, establish the framework and basis of release, and discuss resolutions regarding the implementation of such a disposition option.

These synthesis techniques utilize the molecular recognition properties of many biological molecules to nucleate and control growth of the nanoscale structure. Phage-displayed peptide libraries are a powerful tool to identify peptides that selectively recognize and bind to a variety of inorganic surfaces that are utilized in electronic and photonic devices. These libraries have been used extensively to study the peptide- mediated nucleation and growth of some metallic and semiconducting materials, and the application to designed nanostructures has been demonstrated.

The iron-rich phase is up to 20% denser than any known silicate at the core-mantle boundary. The high mean atomic number of the silicate greatly reduces the seismic velocity and provides an explanation to the low-velocity and ultra-low-velocity zones. Formation of this previously undescribed phase from reaction between the silicate mantle and the iron core may be responsible for the unusual geophysical and geochemical signatures observed at the base of the lower mantle.

Citrate synthase activity of these organisms is of interest due to its key role in acetate metabolism. Prior sequencing of the genome of Geobacter sulfurreducens revealed a putative citrate synthase sequence related to the citrate synthases of eukaryotes. All citrate synthase activity in G. sulfurreducens could be resolved to a single 49-kDa protein via affinity chromatography. The enzyme was successfully expressed at high levels in Escherichia coli with similar properties as the native enzyme, and kinetic parameters were comparable to related citrate synthases (k sub(cat) = 8.3 s super(-1); K sub(m) = 14.1 and 4.3 mu M for acetyl coenzyme A and oxaloacetate, respectively). The enzyme was dimeric and was slightly inhibited by ATP (K sub(i) = 1.9 mM for acetyl coenzyme A), which is a known inhibitor for many eukaryotic, dimeric citrate synthases. NADH, an allosteric inhibitor of prokaryotic hexameric citrate synthases, did not affect enzyme activity. Unlike most prokaryotic dimeric citrate synthases, the enzyme did not have any methylcitrate synthase activity. A unique feature of the enzyme, in contrast to citrate synthases from both eukaryotes and prokaryotes, was a lack of stimulation by K super(+) ions. Similar citrate synthase sequences were detected in a diversity of other Geobacteraceae members. This first characterization of a eukaryotic-like citrate synthase from a prokaryote provides new insight into acetate metabolism in Geobacteraceae members and suggests a molecular target for tracking the presence and activity of these organisms in the environment.

Cell wall anchoring in Staphylococcus aureus occurs by a transpeptidation mechanism requiring surface proteins with C-terminal sorting signals as well as sortase enzymes. The genome sequence of Bacillus anthracis encodes three sortase genes and eleven surface proteins with different types of cell wall sorting signals. Purified B. anthracis sortase A cleaved peptides encompassing LPXTG motif-type sorting signals between the threonine (T) and the glycine (G) residues in vitro. Sortase A activity could be inhibited by thiol-reactive reagents, similar to staphylococcal sortases. B. anthracis parent strain Sterne 34F sub(2), but not variants lacking the srtA gene, anchored the collagen-binding MSCRAMM (microbial surface components recognizing adhesive matrix molecules) BasC (BA5258/BAS4884) to the bacterial cell wall. These results suggest that B. anthracis SrtA anchors surface proteins bearing LPXTG motif sorting signals to the cell wall envelope of vegetative bacilli.

Birch's law revisited AN - 51703293; 2005-048137 AB - Sound velocities of hexagonal close-packed iron (hcp-Fe) were measured at pressures up to 73 gigapascals and at temperatures up to 1700 kelvin with nuclear inelastic x-ray scattering in a laser-heated diamond anvil cell. The compressional-wave velocities (V (sub P) ) and shear-wave velocities (V (sub S) ) of hcp-Fe decreased significantly with increasing temperature under moderately high pressures. V (sub P) and V (sub S) under high pressures and temperatures thus cannot be fitted to a linear relation, Birch's law, which has been used to extrapolate measured sound velocities to densities of iron in Earth's interior. This result means that there are more light elements in Earth's core than have been inferred from linear extrapolation at room temperature.

However, clinical data are very sparse and, in the case of antibody-related proteins, the collected sequences have large variability with only a small subset of variations relevant to the protein pathogenicity (function). On this basis, these sequences represent a model system for development of strategies to recognize the small subset of function-determining variations among the much larger number of primary structure diversifications introduced during evolution. Under such conditions, most protein classification algorithms have limited accuracy. To address this problem, we propose a support vector machine (SVM)-based classifier that combines sequence and 3D structural averaging information. Each amino acid in the sequence is represented by a set of six physicochemical properties: hydrophobicity, hydrophilicity, volume, surface area, bulkiness and refractivity. Each position in the sequence is described by the properties of the amino acid at that position and the properties of its neighbors in 3D space or in the sequence. A structure template is selected to determine neighbors in 3D space and a window size is used to determine the neighbors in the sequence. The test data consist of 209 proteins of human antibody immunoglobulin light chains, each represented by aligned sequences of 120 amino acids. The methodology is applied to the classification of protein sequences collected from patients with and without amyloidosis, and indicates that the proposed modified classifiers are more robust to sequence variability than standard SVM classifiers, improving classification error between 5 and 25% and sensitivity between 9 and 17%. The classification results might also suggest possible mechanisms for the propensity of immunoglobulin light chains to amyloid formation.

How the Chinese household sector develops during the next 50 years will have an important bearing on future aerosol concentrations, because the range of possible outcomes (about 550 Gg yr super(-1)) is greater than total BC emissions in either the United States or Europe (each about 400-500 Gg yr super(-1)). In some Intergovernmental Panel on Climate Change scenarios biofuels persist in rural China for at least the next 50 years, whereas in other scenarios a transition to cleaner fuels and technologies effectively mitigates BC emissions. This paper discusses measures and policies that would help this transition and also raises the possibility of including BC emission reductions as a post-Kyoto option for China and other developing countries.

To describe this relationship, it is necessary to develop new computational approaches at the single-cell level. RESULTS: We have developed AgentCell, a model using agent-based technology to study the relationship between stochastic intracellular processes and behavior of individual cells. As a test-bed for our approach we use bacterial chemotaxis, one of the best characterized biological systems. In this model, each bacterium is an agent equipped with its own chemotaxis network, motors and flagella. Swimming cells are free to move in a 3D environment. Digital chemotaxis assays reproduce experimental data obtained from both single cells and bacterial populations. AVAILABILITY: AgentCell is available on request from the authors.

AN - 67731855; 15824576 AB - The dose assessments for sites containing residual radioactivity usually involve the use of computer models that employ input parameters describing the physical conditions of the contaminated and surrounding media and the living and consumption patterns of the receptors in analyzing potential doses to the receptors. The precision of the dose results depends on the precision of the input parameter values. The identification of sensitive parameters that have great influence on the dose results would help set priorities in research and information gathering for parameter values so that a more precise dose assessment can be conducted. Two methods of identifying site-specific sensitive parameters, deterministic and probabilistic, were compared by applying them to the RESRAD computer code for analyzing radiation exposure for a residential farmer scenario. The deterministic method has difficulty in evaluating the effect of simultaneous changes in a large number of input parameters on the model output results. The probabilistic method easily identified the most sensitive parameters, but the sensitivity measure of other parameters was obscured. The choice of sensitivity analysis method would depend on the availability of site-specific data. Generally speaking, the deterministic method would identify the same set of sensitive parameters as the probabilistic method when 1) the baseline values used in the deterministic method were selected near the mean or median value of each parameter and 2) the selected range of parameter values used in the deterministic method was wide enough to cover the 5th to 95th percentile values from the distribution of that parameter.

One interpretation hypothesizes that technological progress is likely to continue at increasingly higher rates of change. Another interpretation, which includes data from the beginning of the universe to the present, suggests that the universe is approaching a transition point in a logistic development of complexity. This logistic development is similar to the way ideas or products diffuse in a population, i.e., the rate of discovery in a field of knowledge is proportional to the amount discovered & the amount to be discovered. To test a part of this hypothesis, a leading indicator field (fundamental physics) was identified & the events in the history of this field were analyzed. Twelve subfields were identified & grouped into six stages. Each stage seemed to demonstrate a logistic-like development. By analyzing both the median time of development & the characteristic time of development of these stages, the overall development of this one field was found to suggest logistic development. These data seem to indicate that development in fundamental physics is slowing down, with at least one subfield beyond string physics yet to be developed. The data tend to support the hypothesis that a knowledge field can develop logistically. Tables, Figures, References.

Borehole data provide subsurface information that is vital to investigations ranging from local contaminated site assessments to regional water resources studies. However, data in either case are typically sparse, and hole-to-hole correlation of units may be difficult. Evaluating the complexities and associated uncertainties in unit correlations may be performed through 3-D analysis of the data set's covariance and/or transition probabilities. Several data-rich Midwestern study areas show clear structure in 3-D variogram analyses of their aquifer/aquitard frameworks, as well as in their transition probabilities of multiple material types. One of these sites has 700+ boreholes per square km with sampling by continuous split spoons. This high-quality, high-density dataset overcomes the usual problem of studies relying on borehole data: too few data in the horizontal direction. Geostatistical analysis of these data-rich sites provide a means of 1) determining the data density appropriate for understanding spatial hydrogeological structure, and 2) assessing uncertainty and variability in regional studies relying on large databases of relatively sparse drilling data.

Analyses of sediments from Lake Superior suggest that the atmosphere is an important pathway for PBDE transport in the Great Lakes Basin. Atmospheric measurements of PBDEs at locations of the Integrated Atmospheric Deposition Network (IADN) indicate that levels are greater by a factor of 10 in Chicago than in remote locations of the Great Lakes Basin. We will use a one-dimensional process-scale model that couples chemical transport and atmosphere-water exchange mechanisms to evaluate atmospheric deposition of PBTs. A conventional resistance scheme is used to describe the dry atmosphere-water exchange of the vapor- and particle-phase PBDEs. The concentration of PBDEs in the atmospheric compartment will be constrained by the IADN measurements to estimate atmosphere-water exchange over Lake Michigan.

Most investigations into the effect of DMRB on sediment geochemistry utilize various synthetic oxides as the Fe (super III) source (e.g., ferrihydrite, goethite, hematite). These synthetic materials do not represent the mineralogical composition of natural systems, and do not account for the effect of sediment mineral composition on microbially mediated processes. Our experiments with a DMRB (Shewanella putrefaciens 200) and a divalent metal (Zn (super II) ) indicate that, while complexity in sediment mineral composition may not strongly impact the degree of "microbial iron reducibility," it does alter the geochemical consequences of such microbial activity. The ferrihydrite and clay mineral content are key factors. Microbial reduction of a synthetic blend of goethite and ferrihydrite (VHSA-G) carrying previously adsorbed Zn (super II) increased both [Zn (super II) -aq] and the proportion of adsorbed Zn (super II) that is insoluble in 0.5 M HCl. Microbial reduction of Fe (super III) in similarly treated iron-bearing clayey sediment (Fe-K-Q) and hematite sand, which contained minimal amounts of ferrihydrite, had no similar effect. Addition of ferrihydrite increased the effect of microbial Fe (super III) reduction on Zn (super II) association with a 0.5 M HCl insoluble phase in all sediment treatments, but the effect was inconsequential in the Fe-K-Q. Zinc k-edge X-ray absorption spectroscopy (XAS) data indicate that microbial Fe (super III) reduction altered Zn (super II) bonding in fundamentally different ways for VHSA-G and Fe-K-Q. In VHSA-G, ZnO (sub 6) octahedra were present in both sterile and reduced samples; with a slightly increased average Zn-O coordination number and a slightly higher degree of long-range order in the reduced sample. This result may be consistent with enhanced Zn (super II) substitution within goethite in the microbially reduced sample, though these data do not show the large increase in the degree of Zn-O-metal interactions expected to accompany this change. In Fe-K-Q, microbial Fe (super III) reduction transforms Zn-O polyhedra from octahedral to tetrahedral coordination and leads to the formation of a ZnCl (sub 2) moiety and an increased degree of multiple scattering. This study indicates that, while many sedimentary iron minerals are easily reduced by DMRB, the effects of microbial Fe (super III) reduction on trace metal geochemistry are dependent on sediment mineral composition.

The objective of this study was to determine how soil pretreatment affects PLFA analysis and interpretation. Two grinding (ground and control) and five soil sample sizes (0.125-5 g) in factorial combinations were applied to restored or remnant prairie soils. In the restored soil, the smaller soil aliquots were more likely to result in outlying values of community composition, suggesting small-scale heterogeneity in microbial community distribution. Grinding reduced this variability in community composition, with no outliers, even with the lowest size in ground soils. However, grinding increased the abundance of eukaryotic relative to prokaryotic PLFAs, and we hypothesize that grinding exposed root cells and the interior of fungal hyphae to extraction. We suggest that in soils with high root densities, soils should not be ground as grinding may obscure changes in the microbial community by exaggerating the eukaryotic signal from roots. However, in soils with low rooting densities, grinding will reduce heterogeneity and ensure that eukaryotic biomarkers are not underestimated.

AN - 67455992; 15728972 AB - With brilliant synchrotron X-ray sources, microsecond time-resolved synchrotron X-ray radiography and tomography have been used to elucidate the detailed three-dimensional structure and dynamics of high-pressure high-speed fuel sprays in the near-nozzle region. The measurement allows quantitative determination of the fuel distribution in the optically impenetrable region owing to the multiple scattering of visible light by small atomized fuel droplets surrounding the jet. X-radiographs of the jet-induced shock waves prove that the fuel jets become supersonic under appropriate injection conditions and that the quantitative analysis of the thermodynamic properties of the shock waves can also be derived from the most direct measurement. In other situations where extremely axial-asymmetric sprays are encountered, mass deconvolution and cross-sectional fuel distribution models can be computed based on the monochromatic and time-resolved X-radiographic images collected from various rotational orientations of the sprays. Such quantitative analysis reveals the never-before-reported characteristics and most detailed near-nozzle mass distribution of highly transient fuel sprays.

All mammalian and microbial enzymes identified to date are members of the heme oxygenase superfamily and assume similar monomeric structures with an all alpha-helical fold. Here we describe the crystal structures of IsdG and IsdI, two heme-degrading enzymes from Staphylococcus aureus. The structures of both enzymes resemble the ferredoxin-like fold and form a beta -barrel at the dimer interface. Two large pockets found on the outside of the barrel contain the putative active sites. Sequence homologs of IsdG and IsdI were identified in multiple Gram-positive pathogens. Substitution of conserved IsdG amino acid residues either reduced or abolished heme degradation, suggesting a common catalytic mechanism. This mechanism of IsdG-mediated heme degradation may be similar to that of the structurally related monooxygenases, enzymes involved in the synthesis of antibiotics in STREPTOMYCES: Our results imply the evolutionary adaptation of microbial enzymes to unique environments.

Such investigations of extremely small and dilute (super 57) Fe-bearing samples have become possible through the development of SMS. Our results are explained in the framework of the "three-doublet" model, which assumes two Fe (super 2+) -like site and one Fe (super 3+) -like site that are well distinguishable by the hyperfine fields at the location of the Fe nuclei. At low pressures, Fe (super 3+) /Sigma Fe is about 0.40 for both samples. Our results show that at pressures extending into the lowermost mantle the fraction of Fe (super 3+) remains essentially unchanged, indicating that pressure alone does not alter the valence states of iron in (Mg,Fe)SiO (sub 3) perovskite. The quadrupole splittings of all Fe sites first increase with increasing pressure, which suggests an increasingly distorted (noncubic) local iron environment. Above pressures of 40 GPa for Pv10 and 80 GPa for Pv05, the quadrupole splittings are relatively constant, suggesting an increasing resistance of the lattice against further distortion. Around 70 GPa, a change in the volume dependence of the isomer shift could be indicative of the endpoint of a continuous transition of Fe (super 3+) from a high-spin to a low-spin state.

Measured (super 36) Cl/Cl ratios yield apparent residence times from approximately 0.2 to 1.2X10 (super 6) years in the deep (600-1200 m) groundwater (assuming constant Cl) and < or =0.16X10 (super 6) years in the shallow (<600 m) groundwater. Values of delta (super 37) Cl in the groundwater strengthen the application of the (super 36) Cl dating method by constraining Cl sources and identifying groundwater mixing. Dissolved gases were measured in some of the deep groundwater samples. Measured (super 4) He concentrations indicate accumulation of radiogenic (super 4) He that is qualitatively consistent with the age progression indicated by the (super 36) Cl/Cl ratios, but the flux of external (super 4) He from the underlying crust has not been quantified and is not constant throughout the aquifer. Concentrations of (super 40) Ar range from 3.3 to 6.7X10 (super -4) ccSTP/g and indicate excess air incorporation at recharge. Measured (super 40) Ar/ (super 36) Ar ratios do not exceed the atmospheric ratio. A two-dimensional numerical hydrodynamic transect of the aquifer was modeled from the area of the Uweinat Uplift to the northern Bahariya Oasis. Predicted groundwater velocities in the deep portion of the aquifer are 0.5-3.5 m/yr with groundwater residence times up to 9X10 (super 5) years; residence times up to 1.3X10 (super 6) years are predicted in the confining shale. Aquifer properties are estimated by using the model to fit the measured (super 36) Cl/Cl ratios. Under these conditions, hydrodynamic residence times are within about 30% of those calculated from (super 36) Cl when mixing of Cl- is accounted for in the highest-Cl- deep groundwaters. By mutually calibrating multiple methods (hydrodynamic, (super 36) Cl, and (super 4) He), a consistent picture of the Nubian Aquifer has emerged in which lateral flow from a southern recharge area dominates the deep horizons, while shallow horizons contain younger, autochthonous recharge.

In most cases, the effectiveness of the remedial actions in terms of dose savings cannot be demonstrated directly, but can be established with the help of environmental assessment models, through the assessment of future radiological impacts. It should be emphasized that, given the complexity of the processes involved and our current understanding of how they operate, these models are simplified descriptions of the behaviour of radionuclides in the environment and therefore imperfect. One way of testing and improving the reliability of the models is to compare their predictions with real data and/or the predictions of other models. Within the framework of the Remediation Assessment Working Group (RAWG) of the BIOMASS (BIOsphere Modelling and ASSessment) programme coordinated by IAEA, two scenarios were constructed and applied to test the reliability of environmental assessment models when remedial actions are involved. As a test site, an area of approximately 100 ha contaminated by the discharges of an old radium extraction plant in Olen (Belgium) has been considered. In the first scenario, a real situation was evaluated and model predictions were compared with measured data. In the second scenario the model predictions for specific hypothetical but realistic situations were compared. Most of the biosphere models were not developed to assess the performance of remedial actions and had to be modified for this purpose. It was demonstrated clearly that the modeller's experience and familiarity with the mathematical model, the site and with the scenario play a very important role in the outcome of the model calculations. More model testing studies, preferably for real situations, are needed in order to improve the models and modelling methods and to expand the areas in which the models are applicable.

These differences are evident in the variations in lithology, bed thickness and distribution and can impact the interpretation of reservoir potential. Modeling and analysis indicate that the largest changes in insolation occur relatively rapidly, during periods of high eccentricity at the scale of precession. At precession-scale ( approximately 20 kyr), northern and southern hemisphere insolation cycles are 10 kyrs out of phase. The climate of one hemisphere is at a maximum while the other is at a minimum. Consequently, similar climatic successions in opposite hemispheres and associated sediment yield cycles will be 10 kyrs out of phase, as well. Prior to the Plio-Pleistocene, glacioeustatic cycles were controlled by the southern pole because the northern pole could not maintain a significant continental icecap. The result is that similar climatic successions in the northern hemisphere will have yield cycles with distinctly different phase relationships to glacioeustasy than the southern hemisphere. Such differences will not exist in an ice-free world. Evaluating sediment delivery systems and sea level in context with climate change, permits forecasting and high grading of regions prone to maximum coarse yield in and around lowstands; conditions prone to the development of sand rich submarine fans. Where and when fan deposition had the highest probability of occurrence is a function of the existence of an icecap, the hemisphere and the regional climatic succession.

In contrast, the Sakmarian has been interpreted as an icehouse world; a time with low atmospheric CO2 and major glaciation. These "end-member" conditions were not invariant. Milankovitch cycles produced climate changes throughout both these periods. To determine how climates varied, we used the Fast Ocean/Atmosphere Model (FOAM) at Argonne National Laboratory. Insolation extremes occur during periods of high eccentricity combined with the effects of precession, which can generate the highest summer and lowest winter insolation cases, and high obliquity, which can cause the greatest insolation contrast between summer and winter. To evaluate these effects on climate, simulations were run for each end member; one using a precession value placing the northern hemisphere closest to the sun in the summer, and one placing the northern hemisphere farthest from the sun in the summer. The model results showed: (1) interaction of eccentricity and precession is responsible for most climate variation; obliquity being responsible for far less change; (2) eccentricity and precession cause the northern and southern hemisphere climates to be out of phase; (3) within hemispheres, some regions demonstrate large climate changes while others remain stable; (4) climate changes related to Milankovitch cyclicity occur in both greenhouse and icehouse worlds; and (5) climate related processes such as weathering, erosion, sedimentation and deposition will be strongly affected by changes in orbital patterns, as well.

It is commonly accepted that the interfacially active component of crude oil is prevalent in the highest molecular weight, most polar fraction, namely the resins and asphaltenes. We describe the results from a core-flood experiment which suggests there is a role for low molecular weight multifunctional compounds towards enabling surface property alteration. During the core-flood experiment, oil was flowed through a water saturated 1m length siltstone core (porosity, 12%; permeability, 0.01mD) under subsurface conditions (70 degrees C and 7,000psi). Approximately one pore volume of oil was flowed through the core and the experiment was terminated. The siltstone was cut into sections and the core extract petroleum was extracted using organic solvents. The core extract petroleum displayed changes in colour intensity, increasing towards the inlet end of the core. High resolution mass spectrometry indicated the samples from the inlet end of the core were enriched in low molecular weight (100-200 Daltons) pigmented compounds containing one or more; nitrogen, oxygen or sulphur atoms. Environmental Scanning Electron Microscopy was used to observe water spreading phenomena on freshly exposed core surfaces. The changes in water spreading behaviour as described by ESEM along the core indicates that changes in surface wetting tendencies changed gradually from oil-wet at the inlet to water wet at the outlet. We propose that the removal of key surfactant during petroleum migration may impact the nature of crude oil / brine / rock interactions in petroleum accumulations.

However, the step is often error-prone because of its underlying algorithms, which rely mainly on a simple similarity analysis, and lack of guidance from biological rules. We present herein a knowledge-based protein annotation algorithm. Our objectives are to reduce errors and to improve annotation confidences. This algorithm consists of two major components: a knowledge system, called "RuleMiner," and a voting procedure. The knowledge system, which includes biological rules and functional profiles for each function, provides a platform for seamless integration of multiple sequence analysis tools and guidance for function annotation. The voting procedure, which relies on the knowledge system, is designed to make (possibly) unbiased judgments in functional assignments among complicated, sometimes conflicting, information. We have applied this algorithm to 10 prokaryotic bacterial genomes and observed a significant improvement in annotation confidences. We also discuss the current limitations of the algorithm and the potential for future improvement. Proteins 2005.

Measures of energy intensity based on average practice are of little use in corporate management of energy use or for public policy goal setting. In the context of companyor plant-level indicators, it is more useful to have a measure of energy intensity that is capable of indicating where a company or plant lies within a distribution of performance. In other words, is the performance close to (or far from) the industry best practice? This article presents a parametric/statistical approach that can be used to measure best practice, thereby providing a measure of the difference, or "efficiency gap," at a plant, company, or overall industry level. The approach requires plant-level data and applies a stochastic frontier regression analysis used by the ENERGY STAR industrial energy performance indicator (EPI) to energy intensity. Stochastic frontier regression analysis separates energy intensity into three components: systematic effects, inefficiency, and statistical (random) error. The article outlines the method and gives examples of EPI analysis conducted for two industries, breweries and motor vehicle assembly. In the EPI developed with the stochastic frontier regression for the auto industry, the industry median "efficiency gap" was around 27%.

The CMR exploits a metal-insulator transition between a low-T ferromagnetic-metallic ground state and a high-T paramagnetic-insulating phase. The nature of the ferromagnetic-metallic ground state in this manganite remains controversial, and the results are presented here to resolve this problem by showing that its electronic structure is very similar to the pseudogap phase with a nodal-antinodal dichotomous character of the copper oxide high-T superconductors. The results question the assumption that the pseudogap state in the copper oxides and nodal-antinodal dichotomy are signatures of the superconductivity state.

Greenhouse gas emission implications of oil sands recovery and upgrading AN - 17416831; 6530573 AB - Production of oil sands in western Canada has increased significantly in recent years. The processes of recovering and upgrading oil sands require a large amount of steam and hydrogen, the production of which demands considerable energy and generates a large amount of greenhouse gas (GHG) emissions. In fact, the majority of natural gas available in western Canada would be consumed by oil sands operations, if natural gas continues to be the fuel for the operations and if the scale of oil sands operations increases as predicted. Also, the amount of GHG emissions generated from the operations could challenge Canada's ability to meet its Kyoto Treaty commitment, which is to reduce its total GHG emissions. In this paper, we (1) analyze energy use and GHG emissions of Canadian oil sands recovery and upgrading and (2) compare the results with those of (a) current practices (e.g., where steam and hydrogen are produced with natural gas) and (b) alternative practices of providing steam and hydrogen. Although we found that the current practices require a large amount of natural gas and generate significant amounts of GHGs, such alternatives as using nuclear power to provide steam and hydrogen can help reduce natural gas requirements and reduce GHG emissions. In contrast, if coal is used to generate steam and hydrogen, GHG emissions could increase to levels that exceed those associated with current practices. We realize that nuclear-based options are long-term options. However, there is also an anticipated long-term demand for hydrogen for stationary and transportation applications. Although vehicles using hydrogen as a fuel are still.

We estimate that China's emissions were 536 (+/-236) t of total mercury. This value includes open biomass burning, but does not include natural sources or re-emission of previously deposited mercury. Approximately 45% of the Hg comes from non-ferrous metals smelting, 38% from coal combustion, and 17% from miscellaneous activities, of which battery and fluorescent lamp production and cement production are the largest. Emissions are heaviest in Liaoning and Guangdong Provinces, where extensive smelting occurs, and in Guizhou Province, where there is much small-scale combustion of high-Hg coal without emission control devices. Emissions are gridded at 30x30 min spatial resolution. We estimate that 56% of the Hg in China is released as Hg super(0), 32% as Hg super(2+), and 12% as Hg super(p). Particulate mercury emissions are high in China due to heavy burning of coal in residential and small industrial settings without PM controls. Emissions of Hg super(2+) from coal-fired power plants are high due to the absence of flue-gas desulfurization units, which tend to dissolve the soluble divalent mercury. Metals smelting operations favor the production of elemental mercury. Much of the Hg is released from small-scale activities in rather remote areas, and therefore the activity levels are quite uncertain. Also, emissions test data for Chinese sources are lacking, causing uncertainties in Hg emission factors and removal efficiencies. Overall, we calculate an uncertainty level of +/-44% (95% confidence interval) in the estimate of total emissions. We recommend field testing of coal combustors and smelters in China to improve the accuracy of these estimates.

One property is the Rattlesnake Creek (RSC) portion of the Ashland sites. The RSC stream sediments are contaminated with thorium-230, radium-226, and uranium. The US ACE is closing RSC using protocols contained within the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). At RSC, the US ACE developed site-specific derived concentration guideline level (DCGL) cleanup requirements consistent with the MARSSIM guidance. Because of uncertainty about the distribution of contamination within the creek, the US ACE used the Triad approach to collect data and design remedial actions. Systematic planning helped target the areas of concern, develop a conceptual site model, and identify data gaps to be addressed before remediation plans were finalized. Preremediation sampling and analysis plans were designed to be explicitly consistent with final status survey requirements, allowing data sets to support both excavation planning needs and closure requirements in areas where contamination was not encountered above DCGL standards. Judicious use of real- time technologies such as X-ray fluorescence and gamma walkover surveys minimized expensive off- site alpha spectrometry analyses, and at the same time provided the ability to respond to unexpected field conditions.

Quantitation of the abundances of amino acids found at each position in a sequence motif can provide a basis for understanding the structural and functional constraints at each point. Distribution of information across a motif has been used previously, but the non-intuitive nature of the analysis has limited its impact. RESULTS: Here, we introduce a quantitative measure of amino acid sequence diversity (DIVAA) that has a simple, intuitive meaning. Diversity, as a measure of sequence conservation or variation, is inextricably linked to the probability of selecting identical pairs from a distribution. We demonstrate its utility through the analysis of four populations: ATP-binding P-loops, hypervariable domains of kappa light chains, signal sequences, and the N-and C-termini of proteins. DIVAA provides a simple means to generate hypotheses concerning the contribution of individual residues to the functional and evolutionary relationships among proteins.

We report results for the structure of the apatite (100)-water interface obtained with high-resolution specular X-ray reflectivity from a natural growth surface of Durango fluorapatite. A uniform termination at the crystallographic unit-cell boundary was determined. An atomistic model of the interfacial structure is compared to the experimental results and optimized through non-linear least-squares fitting in which the structural parameters were selected to be both physically and chemically plausible. The best-fit structure includes a Ca- and/or F-deficient outermost surface, minimal structural relaxations of the near-surface apatite crystal, and the presence of a layered interfacial water structure exhibiting two distinct water layers. The height of the first water layer is 2.64(9) Aa relative to the relaxed surface with 3.5(1.3) water molecules per surface unit-cell area (64.9 Aa (super 2) ). A second layer of adsorbed water is found 1.53(5) Aa above the first layer, followed by a nearly featureless profile of the bulk liquid water. The layered structure of water is interpreted as being due to hydrogen bonding at the solid-water interface. The interfacial structure shows a strong similarity with the octacalcium phosphate structure projected along a surface normal direction.

The most abrupt change occurs in the narrow compositional range 38% SiO (sub 2) to 33% SiO (sub 2) (Mg (sub 2) SiO (sub 4) ). These structural changes reflect a change from a glass characterized by corner shared SiO (sub 4) tetrahedra and an approximately equal mixture of MgO (sub 4) and MgO (sub 5) polyhedra, to one in which the average coordination of magnesium by oxygen is increased from 4.5+ or -0.1 to 5.0+ or -0.1. Both these local environments are very different from that of their crystalline counterparts. Reverse Monte Carlo (RMC) simulation fits to the experimental neutron, and X-ray diffraction data have been performed to extract the partial radial distribution functions for the enstatite and forsterite glasses. The structural changes are interpreted as a change in the underlying configurational landscape and are considered to be a manifestation of similar structural changes in the stable liquid. These configurational changes are associated with a discontinuous change in the rheological properties of these glass-forming liquids close to the forsterite composition and suggest differences in the transport properties of magnesium silicate liquids at high pressure. Preliminary data on compressed magnesium silicate glasses indicates that higher coordinate Mg-O is expected to be more stable with increasing pressure.

The molecule consists of a typical four-helix antiparallel bundle with overhand connection. However, its oligomerization into a trimer leads to a coiled 'super-helix' which is novel for such bundles. Its central feature, a six-stranded coiled coil, is also novel for proteins. TA1238 does not have strong sequence homologues in databases, but shows strong structural similarity with some proteins in the Protein Data Bank. The function could not be inferred from the sequence but the structure, with some rearrangement, bears some resemblance to the active site region of cobalamin adenosyltransferase (TA1434). Specifically, TA1238 retains Arg104, which is structurally equivalent to functionally critical Arg119 of TA1434. For such conformational change, the overhand connection of TA1238 might need to be involved in a gating mechanism that might be modulated by ligands and/or by interactions with the physiological partners. This allowed us to hypothesize that TA1238 could be involved in cobalamin biosyntheses.

Information on their high-pressure, vibrational dynamic behavior is essential for interpreting seismic observations and for theoretical modeling of the Earth's deep interior. Hydrogen has been suggested as possible lower atomic weight components in the Earth's core. Hydrogen in the core would have profound implications on the H budget within the Earth and our understanding of the physics and chemistry of the core. X-ray diffraction (XRD) experiments show that stoichiometric FeH is formed at 3 GPa from the reaction of Fe and fluid hydrogen, and this compound is stable to at least 62 GPa. With the limitation of XRD alone, however, important geophysical and crystal chemical information about FeH is still lacking. We have conducted nuclear resonant inelastic scattering (NRIXS) experiments on FeH to over 50 GPa in a diamond anvil cell at ambient temperature and at high temperature using laser-heating. The collected NRIXS spectra have been summed, and converted to a partial (Fe related) phonon density of state for final analysis. The initial slope coupled with hydrostatic equation of state data yields VP and VS for comparison to seismic observations for insight into core chemistry and physics.

To address a nation's or a region's water-related sustainability problems, one key element is characterizing and quantifying renewable water resources for better management. Because of limited access and monitoring systems, quantifying renewable water resources in arid and semiarid areas is a great challenge. We developed an integrated approach to improve estimates of renewable water resources. The approach (1) applies spatial and temporal precipitation estimates from multi-satellite data, (2) extracts land use and land cover from remote sensing data, and (3) simulates all watersheds in the region by using a rainfall-runoff model based on interpretation of satellite data. We applied this integrated characterization method to the eastern desert of Egypt, a region where rain gauges and other monitoring systems are extremely sparse. Several satellites, including TRMM, SSM/I, and geostationary IR satellites are currently used to estimate rainfall. NASA recently began producing a merged dataset from multiple satellites yielding precipitation rate with a high temporal and spatial coverage. The TRMM products used include four data sets: (1) 3B40RT combined microwave; (2) 3B41RT, microwave calibrated to geo-IR; and (3) 3B42RT, merged microwave and geo-IR, (4) and the 3B42 multisensor estimates. We used these 1-hr or 3-hr precipitation rate estimates, produced with a 0.25 by 0.25 degree resolution, covering the entire eastern desert, to generate high-resolution precipitation patterns for the eastern desert for 2003 and 2004. These precipitation rates were validated by rainfall the few rain gauges located on the edges of the Eastern Desert. The Eastern Desert of Egypt includes several large-scale watersheds. Spatial integration of remote sensing data (TM, MSS, MODIS) was used to identify land use and land cover (LCLU) and soil types for all watersheds. With improved spatial and temporal precipitation patterns as input, plus distributions of LCLU and soil types, we applied a rainfall-runoff model to determine temporal and spatial distributions for renewable water resources of meteoric origin in each watershed. This estimated overall water budget, based on renewable water resources, provides a quantitative basis for sustainable management.

To identify and quantify renewable groundwater resources, the hydrologic systems of the eastern desert are being studied in a new research program that began in 2003; the effort is supported by the United Nations Development Program and the Global Environmental Facility International Water Program. The Assiuty hydrologic system is an important, complex system in the Eastern Desert, where water demand is high because of progressive, ongoing agricultural development. Previous studies of the Assiuty watershed and our current investigation of groundwater isotopic and geochemical affinities indicate two possible water sources for the shallow groundwater aquifer being investigated: (1) surface water infiltration from runoff caused by sporadic precipitation and (2) upward discharge of deep groundwater from the Nubian aquifer through sub-vertical faults near, and sub-parallel to, the Nile River Graben. In this study, we developed an Assiuty shallow groundwater flow model with constrains on hydrologic properties based on data from 77 wells, calibrated with 19 water level measurements. The results simulated with the final calibrated model suggest that 77% of groundwater in the Assiuty shallow system is replenished from the deep Nubian Aquifer via faults, with 23% or less coming from surface water runoff. Scenarios of future water usage were simulated with the calibrated model and evaluated for sustainable management.

All samples were found to convert entirely or partially into the CaIrO (sub 3) postperovskite structure, which was recently reported for pure MgSiO (sub 3) . The incorporation of Fe greatly reduces the pressure needed for the transition and establishes the new phase as the major component of the D" layer. With the liquid core as an unlimited reservoir of iron, core-mantle reactions could further enrich the iron content in this phase and explain the intriguing seismic signatures observed in the D" layer.

It implements a pathway analysis methodology to evaluate potential radiation exposures resulting from the recycling of contaminated scrap metals and the reuse of surface-contaminated materials and equipment. For modeling purposes, it divides the entire metal recycling process into six steps: (1) scrap delivery, (2) scrap melting, (3) ingot delivery, (4) product fabrication, (5) product distribution, and (6) use of finished product. RESRAD-RECYCLE considers the reuse of surface-contaminated materials in their original forms. It contains representative exposure scenarios for each recycling step and the reuse process; users can also specify scenarios if desired. The model calculates individual and collective population doses for workers involved in the recycling process and for the public using the finished products. The results are then used to derive clearance levels for the contaminated materials on the basis of input dose restrictions. The model accounts for radiological decay and ingrowth, dilution and partitioning during melting, and distribution of refined metal in the various finished products, as well as the varying densities and geometries of the radiation sources during the recycling process. A complete material balance in terms of mass and radioactivity during the recycling process can also be implemented. In an international validation study, the radiation doses calculated by RESRAD-RECYCLE were shown to agree fairly well with actual measurement data.

AN - 66983342; 15492267 AB - The role of putrescine, spermidine and spermine in phorbol 12-myristate-13-acetate (PMA)-induced macrophage differentiation was examined in human HL-60 and U-937 myeloid leukemia cells. Unlike other polyamines, spermine affected this differentiation by acting as a negative regulator. This negative regulation was established by showing that the PMA-induced macrophage phenotype, but not PMA-associated replication arrest, was abrogated (a) by replenishing the PMA-evoked decrease in cellular spermine levels with this polyamine from an exogenous source and (b) by blocking PMA-induced expression of the polyamine catabolic enzyme N(1)-spermidine/spermine acetyltransferase (SSAT) with antisense oligonucleotides in the presence of low substrate level. The PMA-evoked reduction in cellular spermine appears to result from an increase in the activity of SSAT and a decrease in the activity of ornithine decarboxylase, the polyamine biosynthetic enzyme. To a degree, these changes are due to corresponding changes in the expression of the genes that code for these enzymes. When cell differentiation is initiated, SSAT expression is increased after PMA-evoked activation of protein kinase C-beta. The present studies raise the possibility that agents able to reduce spermine levels in patients' myeloid leukemia cells may enhance the activity of differentiation therapy drugs for this type of leukemia.

AN - 67014773; 15506202 AB - Adsorption of uranyl at the surface of calcite was investigated by using batch sorption experiments and synchrotron X-ray standing wave (XSW) measurements. Aqueous solutions containing 236U(VI) (4.5 x 10(-7) to 1.0 x 10(-4) M) and EDTA (5.0 x 10(-7) to 1.1 x 10(-4) M) were reacted for 90 s to 60 min with freshly cleaved calcite (104) surfaces and calcite powders. Surface exchange coefficients, sorption kinetics, and influence of powder surface area/solution volume (SA/V) ratio were investigated by alpha-counting of 236U. Powder sorption results at SA/V = 870 cm2/mL fit a Freundlich isotherm [log [U]surface (in monolayers) = log K + n log [U]aq (in moles/L)], where K = 1.9+/-0.5 and n = 0.9+/-0.1, consistent with uptake of U(VI) by a specific surface reaction where the availability of sorption sites is nonlimiting in the U concentration range measured. Measured U(VI) coverages along this isotherm, based on the calcite (104) surface Ca site density, ranged from 0.04% to 5.4% of a monolayer. Steady state surface coverages were obtained within 90 s. Sorption of U(VI) on calcite (104) single-crystal cleavage surfaces using identical solutions yielded higher coverages, because of increased step density induced by dissolution at the relatively low SA/V ratio (approximately 1) of these measurements. The crystallographic location of the sorbed U(VI) was examined with the synchrotron XSW technique. Measurements were performed at the Advanced Photon Source on fresh calcite (104) cleavage surfaces reacted for 90 s with U(VI) solutions. Coherent fractions for sorbed U ranged from 0.14 to 0.62, and the mean value of the U coherent position was 0.84+/-0.02. This position was independent of dissolved U(VI) concentration and corresponds to a distance between the U atom and the calcite (104) plane of 2.55+/-0.06 A. These results are consistent with U(VI) adsorption atthe calcite surface as an inner-sphere uranyl-carbonate surface complex bonded with the outer oxygen atom(s) of a single surface carbonate group.

The molecule displayed a modified Rossman fold. MoaB is assembled into a hexamer composed of two trimers. The monomers have high structural similarity with two proteins, MogA and MoeA, from the molybdenum cofactor synthesis pathway in E. coli, as well as with domains of mammalian gephyrin and plant Cnx1, which are also involved in molybdopterin synthesis. Structural comparison between these proteins and the amino acid conservation patterns revealed a putative active site in MoaB. The structural analysis of this site allowed to advance several hypothesis that can be tested in further studies.

Through funding from the U.S. Department of Energy (DOE), Argonne National Laboratory, in conjunction with ChevronTexaco and Marathon Oil, developed an innovative, interactive website to provide technically sound, unbiased information about drilling waste management options. The website, known as the Drilling Waste Management Information System (DWMIS), includes a technology description module to familiarize readers with available options, a regulatory module to summarize existing state, federal, and possibly international regulations concerning drilling waste management, and an interactive technology identification module to help users identify waste management options available for their region. The DWMIS will benefit operators by providing easy access to U.S. regulations and waste management options thus allowing them to choose the option with the most environmental and economic benefits. The website will also provide unbiased information to countries developing drilling waste regulations so that the ceuntries will have a basis for allowing operators to use the most economic, environmentally appropriate waste management options, rather than restricting operators to only those options that are commonly used in a particular country. This presentation describes the modules of the website and offers a detailed description of the decision-tree flow chart used in the technology identification module.

In addition to interactive technology description and identification components, DWMIS features a regulatory module. Drilling waste management practices are subject to all applicable federal and state regulatory requirements. The regulatory module of DWMIS is designed to offer a first resource window through (1) providing contact information for state and federal regulatory agencies, including names, addresses, and telephone numbers; (2) offering capsule summaries of state and federal regulations; and (3) referring the reader to agency homepages and the texts of the regulations via Web hyperlinks. This presentation, a companion to Innovative and Interactive Drilling Waste Management Information System (John A. Veil et al.), describes the process of assembling, distilling, and presenting the information condensed into the regulatory module, along with challenges encountered in the process. The overview will include examples and screenshots. JF - 11TH ANNUAL INTERNATIONAL PETROLEUM ENVIRONMENTAL CONFERENCE.

Binding properties of bacteria may also be affected by nutrient and oxygen levels present during their growth. We measured Cd, Co, and Pb adsorption onto bacteria by using (1) bacteria washed with acidic solutions (pH nearly equal 1.5), (2) non-acid-washed bacteria exposed to acidic parent solutions, and (3) non-acid-washed bacteria exposed to neutral parent solutions. The purpose was to determine the effect of acidic conditions on the adsorptive properties of Pseudomonas mendocina, Pseudomonas aeruginosa, Bacillus subtilis, and Bacillus cereus. We also measured Co adsorption onto bacteria (Pseudomonas fluorescens) grown under nutrient-rich and nutrient-limited conditions and onto the facultative bacterium Shewanella oneidensis MR-1 grown under aerobic and anaerobic conditions. Bacteria exposed to acidic solutions adsorbed more metals than bacteria not exposed to such solutions. We attribute the increase in adsorption to the irreversible displacement of structurally bound Mg and Ca by protons. After displacement, the protonated sites can participate in reversible metal adsorption reactions. Thermodynamic modeling suggests that concentrations of functional group sites on bacterial surfaces increase by as much as five times in response to acid washing, assuming that stability constants for the bacterial surface complexes remain the same. Although the sizes of the bacteria changed markedly in response to nutrient limits and oxygen content during growth, the mass-normalized extent of Co adsorption onto both P. fluorescens and S. oneidensis MR-1 was independent of growth conditions. We conclude that adsorption constants derived from experiments in which the bacteria are never exposed to acidic conditions probably provide the most accurate estimates of the extent of bacteria-metal adsorption in natural settings.

The magnetic hyperfine fields derived from the time spectra of the synchrotron Moessbauer spectroscopy show that the low-pressure magnetic phase displays two magnetic hyperfine field sites and that a magnetic collapse occurs at 21 GPa. The magnetic to non-magnetic transition significantly affects the elastic, thermodynamic, and vibrational properties of Fe (sub 3) S. The magnetic collapse of Fe (sub 3) S may also affect the phase relations in the iron-sulfur system, changing the solubility of sulfur in iron under higher pressures. Determination of the physical properties of the non-magnetic Fe (sub 3) S phase is important for the interpretation of the amount and properties of sulfur present in the planetary cores. Sound velocities of Fe (sub 3) S obtained from the measured partial phonon density of states (PDOS) for (super 57) Fe incorporated in the alloy show that Fe (sub 3) S has higher compressional and shear wave velocity than those of hcp-Fe and hcp-Fe (sub 0.92) Ni (sub 0.08) alloy under high pressures, making sulfur a potential light element in the Earth's core based on geophysical arguments. The V (sub P) and V (sub S) of the non-magnetic Fe (sub 3) S follow a Birch's law trend whereas the slopes decrease in the magnetic phase, indicating that the decrease of the magnetic moment significantly affects the sound velocities. If the Martian core is in the solid state containing 14.2 wt.% sulfur, it is likely that the non-magnetic Fe (sub 3) S phase is a dominant component and that our measured sound velocities of Fe (sub 3) S can be used to construct the corresponding velocity profile of the Martian core.

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.

We also analyzed 30 gyrB sequences for B. cereus group strains with published 16S rRNA sequences. Our findings indicated that the three most common species of the B. cereus group, B. cereus, Bacillus thuringiensis, and Bacillus mycoides, were each heterogeneous in all three gene sequences, while all analyzed strains of Bacillus anthracis were found to be homogeneous. Based on analysis of 16S and 23S rRNA sequence variations, the microorganisms within the B. cereus group were divided into seven subgroups, Anthracis, Cereus A and B, Thuringiensis A and B, and Mycoides A and B, and these seven subgroups were further organized into two distinct clusters. This classification of the B. cereus group conflicts with current taxonomic groupings, which are based on phenotypic traits. The presence of B. cereus strains in six of the seven subgroups and the presence of B. thuringiensis strains in three of the subgroups do not support the proposed unification of B. cereus and B. thuringiensis into one species. Analysis of the available phenotypic data for the strains included in this study revealed phenotypic traits that may be characteristic of several of the subgroups. Finally, our results demonstrated that rRNA and gyrB sequences may be used for discriminating B. anthracis from other microorganisms in the B. cereus group.

We found that in frozen RC crystals, QB occupies primarily the proximal binding site. In contrast, our room temperature structure showed that QB is largely in the distal position. Both data sets were collected in dark-adapted conditions. We estimate that the occupancy of the QB site is 80% with a proximal: distal ratio of 4:1 in frozen RC crystals. We could not separate the effect of freezing from the effect of the cryoprotectants ethylene glycol or glycerol. These results could have far-reaching implications in structure/function studies of electron transfer in the acceptor quinone complex because the above are the most commonly used cryoprotectants in spectroscopic experiments.

Sorting and attachment of these proteins is directed by C-terminal signals. Sortase B of S. aureus recognizes a motif NPQTN, cleaves the polypeptide after the Thr residue, and attaches the protein to pentaglycine cross-bridges. Sortase B of B. anthracis is thought to recognize the NPKTG motif, and attaches surface proteins to m-diaminopimelic acid cross-bridges. We have determined crystal structure of sortase B from B. anthracis and S. aureus at 1.6 and 2.0 Aa resolutions, respectively. These structures show a beta -barrel fold with alpha -helical elements on its outside, a structure thus far exclusive to the sortase family. A putative active site located on the edge of the beta -barrel is comprised of a Cys-His-Asp catalytic triad and presumably faces the bacterial cell surface. A putative binding site for the sorting signal is located nearby.

Beryllium-7 is produced in the upper troposphere and lower stratosphere and after formation rapidly attaches itself to fine aerosol particles. Measurements of super(7)Be at ground level can therefore be used as a tracer of stratospheric/tropospheric folding events, leading to injection of ozone and upper atmospheric aerosols into the lower atmosphere. Since its concentration varies little on regional scales it can also be used to detect and correct for sampling problems in particulate monitoring networks. Lead-210 and its progeny, super(210)Bi, and super(210)Po can also be used to determine the apparent tropospheric residence times for fine aerosols by looking at the super(210)Bi/ super(210)Pb and super(210)Po/ super(210)Pb activity ratios. Reported here are measurements of the natural radionuclides super(7)Be and super(210)Pb, taken at two sites near Pittsburgh, PA in the summer of 2001 and at a site near Centerton, New Jersey in 1999 during the NEOPS field campaign. Beryllium-7 results show no evidence of upper atmospheric input during the sampling period. Apparent residence times as calculated from super(210)Po/ super(210)Pb ratios are shorter for Pittsburgh than for Centerton, and shorter for both sites than those obtained previously in other areas, indicating a local aerosol source as well as a higher loading of water-soluble species such as sulfate and nitrate. A comparison of fine and course aerosol lifetimes shows no contribution of excess super(210)Po from wind-blown soil or from coal-fired power plants.

AN - 72001335; 15180044 AB - The detonation of a radiological dispersal device (RDD) could produce significant social and economic damage, the extent of which would depend largely on how quickly and effectively cleanup levels were established and on public acceptance of those levels. This paper shows that current radiological cleanup laws and regulations, models for converting dose or risk goals to cleanup concentrations, and existing site-specific criteria were not designed specifically for RDD cleanups but, absent changes, would apply by default. The goals and approaches of these legal and methodological structures often conflict; using them in response to terrorism could undermine public confidence, cause delays, and produce unnecessary costs or unacceptable cleanups. RDD cleanups would involve immediate priorities not envisioned in the existing radiological cleanup framework, such as balancing radiation risks with the health, economic, and other societal impacts associated with access to the infrastructure necessary to sustain society (e.g., hospitals, bridges, utilities). To minimize the achievement of terrorism goals, the elements of an RDD cleanup response--including updating existing legal/regulatory structures to clarify federal authority, goals, and methods for developing RDD cleanup criteria--must be in place soon; given the complexity of the issues and the potential societal impact, this effort should be expedited.

The empirical approach uses statistical modeling to develop a relationship between the radiances observed at the satellite and in situ measurements of sediment concentration. The semi-analytical approach begins with the theoretical relationships between the concentrations in the water and the expected radiances received at the satellite. In either case, the algorithm depends on the particular sensor of concern, and the success of the retrievals tends to vary with the location and time of year, limiting the general utility of the results. We have used in situ data collected from southern Lake Michigan during the EEGLE and observations from SeaWiFS to develop a single-channel (550 nm) semi-analytical algorithm for suspended sediment concentration. By using Bayesian statistical methods along with a linked hydrodynamic, sediment-transport model, we were able to assess the performance of the algorithm as applied to different regions of Lake Michigan at different times of the year. Our results show that the relationship is robust though the sensitivity of the concentration estimates to the reflectance increases at higher (> 5 mg/L) sediment concentrations.

Quantitative analysis of peptide population sequence diversity and bias patterns has the power to significantly enhance the impact of these methods. We have developed a suite of computational tools for the analysis of peptide populations and made them accessible by integrating fifteen software programs for the analysis of combinatorial peptide sequences into the REceptor LIgand Contacts (RELIC) relational database and web-server. These programs have been developed for the analysis of statistical properties of peptide populations; identification of weak consensus sequences within these populations; and the comparison of these peptide sequences to those of naturally occurring proteins. RELIC is particularly suited to the analysis of peptide populations affinity selected with a small molecule ligand such as a drug or metabolite. Within this functional context, the ability to identify potential small molecule binding proteins using combinatorial peptide screening will accelerate as more ligands are screened and more genome sequences become available. The broader impact of this work is the addition of a novel means of analyzing peptide populations to the phage display community.

In an attempt to simplify the fluidic requirements for integrated biodetection systems, we used tunable surface microparticles both as an rRNA affinity purification resin in a renewable microcolumn sample preparation system and as the sensor surface in a flow cytometer detector. The tunable surface detection limits in both low- and high-salt buffers were 1 ng of total RNA ( similar to 10 super(4) cell equivalents) in 15-min test tube hybridizations and 10 ng of total RNA ( similar to 10 super(5) cell equivalents) in hybridizations with the automated system (30-s contact time). RNA fragmentation was essential for achieving tunable surface suspension array specificity. Chaperone probes reduced but did not completely eliminate cross-hybridization, even with probes sharing <50% identity to target sequences. Nonpurified environmental extracts did not irreparably affect our ability to classify color-coded microparticles, but residual environmental constituents significantly quenched the Alexa-532 reporter fluor. Modulating surface charge did not influence the interaction of soluble environmental contaminants with conjugated beads. The automated system greatly reduced the effects of fluorescence quenching, especially in the soil background. The automated system was as efficacious as manual methods for simultaneous sample purification, hybridization, and washing prior to flow cytometry detection. The implications of unexpected target cross-hybridization and fluorescence quenching are discussed relative to the design and implementation of an integrated microbial monitoring system.

Even with a less efficient but higher power density 0.6 V per cell than the base case 0.7 V per cell at the rated power point, the hydrogen fuel cell vehicles are projected to offer essentially the same fuel economy multiplier. The key to obtaining high fuel economy as measured on standardized urban and highway drive schedules lies in maintaining high efficiency of the fuel cell (FC) system at low loads. To achieve this, besides a high performance fuel cell stack, low parasitic losses in the air management system (i.e., turndown and part load efficiencies of the compressor-expander module) are critical.

With over 100 genomes completely sequenced and countless more to follow, the next frontier for biological science will be bringing `genomes to life' through a complete, predictive understanding of biological entities in their natural environments. Although organisms and model systems vary, the experimental and technological path to quantitatively connect genotype with phenotype begins with the analysis of global mRNA expression, for without mRNA there are no proteins to study or metabolic fluxes to measure. However, simply participating in global expression profiling experiments presupposes a significant up-front investment in organism- and gene system-specific oligonucleotides or cDNA probes, a practical and pervasive bottleneck that continues to limit microarray technology, global expression profiling and systems biology studies to large laboratories with relatively deep pockets. In this issue, Roth et al. address this problem using a microarray platform for gene expression analysis designed to be applicable to any biological system.

This seemingly simple cost effectiveness methodology requires making careful choices, such as whether to employ (1) user costs or societal costs, (2) manufacturer- or consumer-level costs, (3) emission reductions in non-attainment areas only or in both non-attainment and attainment areas, and (4) annual or pollution-season emission reductions. Researchers must also carefully consider how to determine baseline emissions, whether to use multiple-pollutant emission reductions, and whether to apply emission discounting. Because there are various ways to address these issues and because different studies employ different assumptions regarding costs and emission reductions, the results of cost effectiveness studies can be significantly different and can sometimes contradict one another. This paper summarizes and adjusts the cost effectiveness results from completed studies, allowing determination of the relative cost effectiveness of key mobile source emission control measures. The paper also summarizes the cost effectiveness of stationary control measures, permitting a comparison of mobile and stationary control measures. The results of this study indicate that, except for alternative-fuel vehicles (and considering a range of uncertainties), the emission control cost of many mobile source control measures is below $10,000 per ton of emissions reduced.

(super 81) Kr ages range from approximately 2 X 10 (super 5) to approximately 1 X 10 (super 6) yr, correlate with (super 36) Cl/Cl ratios, and are consistent with lateral flow of groundwater from a recharge area near the Uweinat Uplift in SW Egypt. Low delta (super 2) H values of the (super 81) Kr-dated groundwater reveal a recurrent Atlantic moisture source during Pleistocene pluvial periods. These results indicate that the (super 81) Kr method for dating old groundwater is robust and such measurements can now be applied to a wide range of hydrologic problems.

Site conditions and landscape context are critical factors influencing the functions that created wetlands perform. We developed a spatial model and used a geographic information system (GIS) to identify suitable locations for wetland mitigation sites. The model used six variables to characterize site conditions: hydrology, soils, historic condition, vegetation cover, adjacent vegetation, and land use. For each variable, a set of suitability scores was developed that indicated the wetland establishment potential for different variable states. Composite suitability scores for individual points on the landscape were determined from the weighted geometric mean of suitability scores for each variable at each point. These composite scores were grouped into five classes and mapped as a wetland mitigation suitability surface with a GIS. Sites with high suitability scores were further evaluated using information on the feasibility of site modification and project cost. This modeling approach could be adapted by planners for use in identifying the suitability of locations as wetland mitigation sites at any site or region.

The process uses 96-well plates and is automated from the level of primer design to the detection of soluble protein by a tag detection screen. This process was applied to a set of cytoplasmic targets from Bacillus subtilis to produce clones expressing soluble protein for incorporation into the structure determination pipeline of the Midwest Center for Structural Genomics. We also evaluated the feasibility of these plate-based methods for domain-based cloning and expression of secretory proteins and putative soluble domains of membrane proteins. This approach shows promise for implementation in a high throughput format and could provide additional target resources for structure determination. The continued development of new technologies that can be implemented in an automated format will be essential for continued success in the structural genomic programs.

Samples from this class of proteins are not only difficult to produce in quantities sufficient for analysis by X-ray diffraction or NMR, but their hydrophobic properties add extra dimension to their purification and subsequent crystallization. New systems that seek to tackle the production problems are in development. In our laboratory, one such strategy exploits the unique physiology of the Rhodobacter species of photosynthetic bacteria where we have designed an overexpression system that coordinates the heterologous production of targeted hydrophobic proteins with nascent, unfilled membranes that can be used to harbor them. In this study, we describe the means by which purification of recombinant membrane proteins produced in such a fashion can be purified efficiently from Rhodobacter membranes using relatively higher-throughput, semi-automated methods. These protocols utilize a state-of-the-art FPLC super(TM) system for affinity chromatography, followed by gel filtration or ion exchange chromatography to enhance purity for crystallization attempts. The Rhodobacter expression system coupled with the semi-automation of purification steps represents an advance towards the development of a strategy for obtaining structures for membrane proteins at a more rapid pace.

The additional challenge in structural genomics is the need to produce high numbers of proteins with low sequence similarities and poorly characterized or unknown properties. 'Structural-biology-grade' proteins must be generated in a quantity and quality suitable for structure determination experiments using X-ray crystallography or nuclear magnetic resonance (NMR). The choice of protein purification and handling procedures plays a critical role in obtaining high-quality protein samples. The purification procedure must yield a homogeneous protein and must be highly reproducible in order to supply milligram quantities of protein and/or its derivative containing marker atom(s). At the Midwest Center for Structural Genomics we have developed protocols for high-throughput protein purification. These protocols have been implemented on AKTA EXPLORER 3D and AKTA FPLC 3D workstations capable of performing multidimensional chromatography. The automated chromatography has been successfully applied to many soluble proteins of microbial origin. Various MCSG purification strategies, their implementation, and their success rates are discussed in this paper. abbreviations MCSG - Midwest Center for Structural Genomics; IMAC - immobilized metal affinity chromatography; TEV - tobacco etch virus; - beta -ME - beta -mercaptoethanol; DTT - dithiothreitol; EDTA - ethylenediaminetetraacetate; SDS-PAGE - polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate.

Protein Expr. Purif. 29, 311-320]. The method greatly reduces the time and effort needed to produce native proteins for structural or functional studies. We now demonstrate that the approach is also well suited for production of proteins in defined media with incorporation of selenomethionine to facilitate structure determination by multiwavelength anomalous diffraction. Induction of a random set of Bacillus stearothermophilus target genes under the new protocols generated soluble selenomethionyl proteins in good yield. Several selenomethionyl proteins were purified in good yields and three were subjected to amino acid analysis. Incorporation of selenomethionine was determined to be greater than 95% in one protein and greater than 98% in the other two. In the preceding paper [Zhao et al., this issue, pp. 87-93], the approach is further extended to production of [U- super(15)N]- or [U- super(13)C, U- super(15)N]-labeled proteins. The approach thus appears suitable for high-throughput production of proteins for structure determination by X-ray crystallography or nuclear magnetic resonance spectroscopy.

The protein contains a three-heme core that is surrounded by 71 amino acid residues. An unusual feature of this cytochrome is that it has 17 lysine residues, but only nine hydrophobic residues that are larger than alanine. The details of the structure are described and compared with those of cytochrome c sub(7) from Desulfuromonas acetoxidans and with cytochromes c sub(3). The two cytochrome c sub(7) molecules have sequences that are 46% identical, but the arrangements of the hemes in the two structures differ; the rms deviation of all alpha -carbons is 2.5 AA. These cytochromes can reduce various metal ions. The reduction site of the chromate ion in D. acetoxidans is occupied by a sulfate ion in the crystal structure of PpcA. We identified four additional homologues of cytochrome c sub(7) in the G. sulfurreducens genome and three polymers of c sub(7)-type domains. Of the polymers, two have four repeats and one has nine repeats. On the basis of sequence alignments, one of the hemes in each of the cytochrome c sub(7)-type domains does not have the bis-histidine coordination. The packing of the molecules in the crystal structure of PpcA suggests that the polymers have an elongated conformation and might form a "nanowire".

Using a combination of amino acid sequence analysis, three-dimensional crystal structure information, and kinetic analysis, we have characterized TA0175 as phosphoglycolate phosphatase from Thermoplasma acidophilum. The crystal structure of TA0175 revealed two distinct domains, a larger core domain and a smaller cap domain. The large domain is composed of a centrally located five-stranded parallel beta -sheet with strand order S10, S9, S8, S1, S2 and a small beta -hairpin, strands S3 and S4. This central sheet is flanked by a set of three alpha -helices on one side and two helices on the other. The smaller domain is composed of an open faced beta -sandwich represented by three antiparallel beta -strands, S5, S6, and S7, flanked by two oppositely oriented alpha -helices, H3 and H4. The topology of the large domain is conserved; however, structural variation is observed in the smaller domain among the different functional classes of the haloacid dehalogenase superfamily. Enzymatic assays on TA0175 revealed that this enzyme catalyzed the dephosphorylation of phosphoglycolate in vitro with similar kinetic properties seen for eukaryotic phosphoglycolate phosphatase. Activation by divalent cations, especially Mg super(2+), and competitive inhibition behavior with Cl super(-) ions are similar between TA0175 and phosphoglycolate phosphatase. The experimental evidence presented for TA0175 is indicative of phosphoglycolate phosphatase.

AN - 80150553; 14768865 AB - Green rusts, mixed Fe(II)/Fe(III) hydroxide minerals present in many suboxic environments, have been shown to reduce a number of organic and inorganic contaminants. The reduction of halogenated ethanes was examined in aqueous suspensions of green rust, both alone and with the addition of Ag(I) (AgGR) and Cu(II) (CuGR). Hexachloroethane (HCA), pentachloroethane (PCA), 1,1,1,2-tetrachloroethane (1,1,1,2-TeCA), 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA), 1,1,1-trichloroethane (1,1,1-TCA), 1,1,2-trichloroethane (1,1,2-TCA), 1,1-dichloroethane (1,1-DCA), and 1,2-dibromoethane were reduced in the presence of green rust alone, AgGR, or CuGR; only 1,2-dichloroethane and chloroethane were nonreactive. The reduction was generally more rapid for more highly substituted ethanes than for ethanes having fewer halogen groups (HCA > PCA > 1,1,1,2-TeCA > 1,1,1-TCA > 1,1,2,2-TeCA > 1,1,2-TCA > 1,1-DCA), and isomers with the more asymmetric distributions of halogen groups were more rapidly reduced than the isomer with greater symmetry (e.g., 1,1,1-TCA > 1,1,2-TCA). The addition of Ag(I) or Cu(II) to green rust suspensions resulted in a substantial increase in the rate of halogenated ethane reduction as well as significant differences in the product distributions with respect to green rust alone.

AN - 71558103; 14592740 AB - Changes in the microbial community during bioremediation of explosives-contaminated soil in a molasses-fed bioslurry process were examined. Upon addition of molasses to laboratory-scale reactors, total culturable heterotrophs increased rapidly by three to four orders of magnitude. However, heat-shocked heterotrophs and the percentage of gram-positive bacterial isolates did not increase until the soluble concentrations of 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrobenzene (TNB) began to decrease. The number of identified phospholipid fatty acids (PLFA) and the total PLFA concentration also exhibited an immediate increase in response to molasses addition, while the concentration of branched PLFA, indicative of the gram-positive population, remained low until soluble TNT and TNB concentrations had significantly decreased. This same general relationship between explosives degradation and gram-positive-specific PLFA was observed during an experiment with a large field-scale bioslurry lagoon reactor. These results indicate that the gram-positive organisms, which have been shown to be severely impacted by even low concentrations of TNT and TNB [Current Microbiol. 35 (1997) 77; Environ. Toxicol. Chem. 17 (1998) 2185], are able to increase in concentrations after explosives compounds are reduced to non-inhibitory levels, and should therefore be able to reestablish themselves in remediated soils.

This finding, coupled with the observation of Tc spectral lines in certain stars, shows that the majority of presolar SiC grains come from low-mass asymptotic giant branch stars, and that the amount of (super 99) Tc produced in such stars is insufficient to have left a detectable (super 99) Ru anomaly in early solar system materials.

Unit-cell volumes of a powdered sample were determined in situ as a function of pressure up to 27 GPa in a diamond anvil cell (DAC), by using angle-dispersive synchrotron X-ray diffraction (XRD) techniques. Unit-cell volumes were fitted to a Birch-Murnaghan equation of state, resulting in a room-temperature bulk modulus for the zircon structure, K (sub TO) = 199+ or -1 GPa, and ambient pressure unit-cell volume V (sub 0) = 260.89+ or -0.03 Aa (super 3) , when (delta K (sub T0) /delta P) (sub T) = K' (sub T0) is fixed at 4. This bulk modulus is over 12% lower than that suggested by earlier measurements using impure, natural zircon sample. In addition, we observed the start of the transformation of zircon to reidite (scheelite-structured ZrSiO (sub 4) ) at a pressure of 19.7 GPa, over 3 GPa lower than previously determined for natural (impure) zircon. Together with compressibility measurements of a trace-element-doped zircon, these observations suggest that impurities affect the phase transition kinetics and compressibility of zircon, and by analogy, perhaps of other silicate minerals.

A genotyping array targeting four virulence factor genes in enterohemorrhagic Escherichia coli (EHEC) was tested. The arrays were clearly able to differentiate between E. coli O157:H7 genotypes and E. coli O91:H2. Non-pathogenic E. coli and non-target organisms were not detected on this array. In the second study, an hsp70 gene single nucleotide polymorphism (SNP) array for specific Cryptosporidium parvum detection was constructed to differentiate between principle genotypes. SNPs, and hence differences between genotypes, were easily detected on this type of array. In the third study an array for Helicobacter pylori was tested for simultaneous SNP discrimination and presence or absence of virulence factor genes. Results from this study showed that both SNP discrimination for some conserved genes, and the presence or absence of virulence factor genes was possible. In the fourth study, multiplexing was achieved by direct hybridization and detection of mRNA to the array. For highly expressed genes, visible signal was detected at 312.5 ng of total RNA, indicating that these new methods may have sufficient environmental sensitivity without the need to perform PCR.

However, averting these health damages by investing in clean energy and industrial technologies and measures can be expensive. Many cities do not have the capital to make such investments or may prefer to invest that capital elsewhere. In this article, we examine the city of Shanghai, China, and perform an illustrative cost/benefit analysis of air pollution control. Between 1995 and 2020 we expect that Shanghai will continue to grow rapidly. Increased demands for energy will cause increased use of fossil fuels and increased emissions of air pollutants. In this work, we examine emissions of particles smaller than 10 mu m in diameter (PM10), which have been associated with inhalation health effects. We hypothesize the establishment of a new technology strategy for coal-fired power generation after 2010 and a new industrial coal-use policy. The health benefits of pollution reduction are compared with the investment costs for the new strategies. The study shows that the benefit-to-cost ratio is in the range of 1-5 for the power-sector initiative and 2-15 for the industrial-sector initiative. Thus, there appear to be considerable net benefits for these strategies, which could be very large depending on the valuation of health effects in China today and in the future. This study therefore provides economic grounds for supporting investments in air pollution control in developing cities like Shanghai.

However, for assigning proteins to an attribute class within a family these methods may introduce more free parameters than are needed. There are fewer members and there is less variability among sequences within a family. We describe a method for organizing proteins in a family that exhibits up to an order of magnitude reduction in the number of parameters. The basis is the log odds ratio commonly used to measure similarity. We adapt this to characterize the sequence dissimilarities that give rise to attribute differentiation. This leads to the definition of Class Attribute Substitution Matrices (CLASSUM), a dual of the BLOSUM. Results: The method was applied to classify sequences hierarchically in the lambda and kappa subgroups of the immunoglobulin superfamily. Positions conferring class were identified based on the degree of amino acid variability at a position. The CLASSUM computed for these positions classified better than 90% of test data correctly compared with 35-50% for BLOSUM-62. The expected value for a random matrix is 14%. The results suggest that family-specific data- derived substitution matrices can improve the resolution of automated methods that use generic substitution matrices for searching for and classifying proteins.

A screening risk assessment was conducted to determine if measured concentrations of DU-associated radionuclides in site soils exceed radionuclide levels considered protective of biota. While concentrations of individual radionuclides did not exceed acceptable levels, total radionuclide concentrations could result in potentially unacceptable doses to exposed biota. Thus, a receptor-specific assessment was conducted to estimate external and internal radiological doses to vegetation and wildlife known or expected to occur at the sites. Wildlife evaluated included herbivores, omnivores, and top-level predators. Internal dose estimates to wildlife considered exposure via fugitive dust inhalation and soil and food ingestion; root uptake was the primary exposure route evaluated for vegetation. Total doses were compared with acceptable dose levels of 1.0 and 0.1 rad/day for vegetation and wildlife, respectively, with potentially unacceptable risks indicated for doses exceeding these levels. All estimated doses were below or approximated acceptable levels, typically by an order of magnitude or more. These results indicate that current levels of DU in soils do not pose unacceptable radiological risks to biota at the sites evaluated.

Studies to evaluate the energy and emission impacts of vehicle/fuel systems have to address allocation of the energy use and emissions associated with petroleum refineries to various petroleum products because refineries produce multiple products. The allocation is needed in evaluating energy and emission effects of individual transportation fuels. Allocation methods used so far for petroleum-based fuels (e.g., gasoline, diesel, and liquefied petroleum gas [LPG]) are based primarily on mass, energy content, or market value shares of individual fuels from a given refinery. The aggregate approach at the refinery level is unable to account for the energy use and emission differences associated with producing individual fuels at the next sub-level: individual refining processes within a refinery. The approach ignores the fact that different refinery products go through different processes within a refinery. Allocation at the subprocess level (i.e., the refining process level) instead of at the aggregate process level (i.e., the refinery level) is advocated by the International Standard Organization. In this study, we seek a means of allocating total refinery energy use among various refinery products at the level of individual refinery processes. Main Features. We present a petroleum refinery-process-based approach to allocating energy use in a petroleum refinery to petroleum refinery products according to mass, energy content, and market value share of final and intermediate petroleum products as they flow through refining processes within a refinery. The approach is based on energy and mass balance among refining processes within a petroleum refinery. By using published energy and mass balance data for a simplified U.S. refinery, we developed a methodology and used it to allocate total energy use within a refinery to various petroleum products. The approach accounts for energy use during individual refining processes by tracking product stream mass and energy use within a refinery. The energy use associated with an individual refining process is then distributed to product streams by using the mass, energy content, or market value share of each product stream as the weighting factors. Results. The results from this study reveal that product-specific energy use based on the refinery process-level allocation differs considerably from that based on the refinery-level allocation. We calculated well-to-pump total energy use and greenhouse gas (GHG) emissions for gasoline, diesel, LPG, and naphtha with the refinery process-based allocation approach. For gasoline, the efficiency estimated from the refinery-level allocation underestimates gasoline energy use, relative to the process-level-based gasoline efficiency. For diesel fuel, the well-to-pump energy use for the process-level allocations with the mass- and energy-content-based weighting factors is smaller than that predicted with the refinery-level allocations. However, the process-level allocation with the market-value-based weighting factors has results very close to those obtained by using the refinery-level allocations. For LPG, the refinery-level allocation significantly overestimates LPG energy use. For naphtha, the refinery-level allocation overestimates naphtha energy use. The GHG emission patterns for each of the fuels are similar to those of energy use. Conclusions. We presented a refining-process-level-based method that can be used to allocate energy use of individual refining processes to refinery products. The process-level-based method captures process-dependent characteristics of fuel production within a petroleum refinery. The method starts with the mass and energy flow chart of a refinery, tracks energy use by individual refining processes, and distributes energy use of a given refining process to products from the process. In allocating energy use to refinery products, the allocation method could rely on product mass, product energy contents, or product market values as weighting factors. While the mass- and energy-content-based allocation methods provide an engineering perspective of energy allocation within a refinery, the market-value-based allocation method provides an economic perspective. The results from this study show that energy allocations at the aggregate refinery level and at the refining process level could make a difference in evaluating the energy use and emissions associated with individual petroleum products. Furthermore, for the refining-process-level allocation method, use of mass - energy content - or market value share-based weighting factors could lead to different results for diesel fuels, LPG, and naphtha. We suggest that, when possible, energy use allocations should be made at the lowest subprocess level - a confirmation of the recommendation by the International Standard Organization for life cycle analyses. Outlook. The allocation of energy use in petroleum refineries at the refining process level in this study follows the recommendation of ISO 14041 that allocations should be accomplished at the subprocess level when possible. We developed a method in this study that can be readily adapted for refineries in which process-level energy and mass balance data are available. The process-level allocation helps reveal some additional energy and emission burdens associated with certain refinery products that are otherwise overlooked with the refinery-level allocation. When possible, process-level allocation should be used in life-cycle analyses.

Astronomical evidence for the formation of SiC in expanding circumstellar atmospheres of asymptotic giant branch (AGB) carbon stars is provided by infrared (IR) studies. However, identification of the crystallographic structure of SiC from IR spectra is controversial. Since >95% of the presolar SiC isolated from meteorites formed around carbon stars, a determination of the structure of presolar SiC is, to first order, a direct determination of the structure of circumstellar SiC. We therefore determined the polytype distribution of presolar SiC from the Murchison CM2 carbonaceous meteorite using analytical and high-resolution transmission electron microscopy (TEM). High-resolution lattice images and electron diffraction of 508 individual SiC grains demonstrate that only two polytypes are present, the cubic 3C (beta -SiC) polytype (79.4% of population by number) and the hexagonal 2H (alpha -SiC) polytype (2.7%). Intergrowths of these two polytypes are relatively abundant (17.1%). No other polytypes were found. A small population of one-dimensionally disordered SiC grains (0.9%), whose high density of stacking faults precluded classification as any polytype, was also observed. The presolar origin of 2H alpha -SiC is unambiguously established by tens-of-nanometers-resolution secondary ion mass spectroscopy (NanoSIMS). Isotopic maps of a TEM-characterized 2H alpha -SiC grain exhibit non-solar isotopic compositions of (super 12) C/ (super 13) C = 64+ or -4 and (super 14) N/ (super 15) N = 575+ or -24. These measurements are consistent with mainstream presolar SiC thought to originate in the expanding atmospheres of AGB carbon stars. Equilibrium condensation calculations together with inferred mineral condensation sequences predict relatively low SiC condensation temperatures in carbon stars. The laboratory observed condensation temperatures of 2H and 3C SiC are generally the lowest of all SiC polytypes and fall within the predictions of the equilibrium calculations. These points account for the occurrence of only 2H and 3C polytypes of SiC in circumstellar outflows. The 2H and 3C SiC polytypes presumably condense at different radii (i.e., temperatures) in the expanding stellar atmospheres of AGB carbon stars. Abstract Copyright (2003) Elsevier, B.V.

It has provided a means of soliciting stakeholder input before key decisions are made. The projects developed under the ACWA Program are characterized as major federal actions and therefore also must meet the requirements of the National Environmental Policy Act (NEPA). One of these is the requirement for public participation in the environmental impact assessment process. This case study describes the ACWA Dialogue and NEPA processes, and examines their relationship in the implementation of the ACWA Program. The examination suggests that involving the public at the beginning of a program through a Dialogue-like process can introduce environmental considerations early in the project development process and contribute to the development of a more informed public. These factors improve the overall efficacy of public participation, strengthening the link between project development and environmental assessment in a manner consistent with the original intent of NEPA.

We assessed root turnover with the use of an isotope tracer in two forest free-air carbon dioxide enrichment experiments. Growth at elevated carbon dioxide did not accelerate root turnover in either the pine or the hardwood forest. Turnover of fine root carbon varied from 1.2 to 9 years, depending on root diameter and dominant tree species. These long turnover times suggest that root production and turnover in forests have been overestimated and that sequestration of anthropogenic atmospheric carbon in forest soils may be lower than currently estimated.

This is a fossil groundwater reservoir with recharge that is minor compared to natural discharge and pumping for agricultural and industrial use.a Its water volume ( approximately 5X10 (super 4) km (super 3) ) is equivalent to about 500 years of Nile River discharge. Although there have been a large number of radiocarbon analyses of Nubian aquifer water, indicating that some samples have ages (mean residence times) = 5X10 (super 4) years, and hydrologic models indicate ages up to 10 (super 6) a, there has not yet been a definitive measurement of the age of the Nubian aquifer water and its variation along flowpath. An outstanding question is whether recharge has been restricted mainly to the highlands in the southwest, or has been distributed regionally, during humid climate periods during the Quaternary; each of these recharge modes results in a different distribution of natural radioactive tracers within the aquifer. We address this question using measurements of (super 81) Kr, a new tool for groundwater dating. (super 81) Kr has been recognized as an ideal tracer for groundwater dating in the 50,000-1,000,000-year range, but its low abundance ( approximately 10 (super 3) atoms/L H (sub 2) O) has made routine measurement nearly intractable. We have applied a new analytical method, atom-trap trace analysis (ATTA) (Chen et al., 1999, Science), to measure the (super 81) Kr abundance in samples of Nubian aquifer groundwater. Six groundwater samples were taken from wells screened in the deeper portion of the aquifer (600-1200 m) in major oasis areas of the Western Desert (Baris, Kharga, Dakhla, Farafra, Bahariya). Dissolved gas was bulk-stripped from water in the field. The Kr was separated from the bulk gas and analyzed by low-level counting (LLC) for (super 85) Kr at Bern. It was then spiked with (super 85) Kr, analyzed again by LLC, and shipped to Argonne for analysis of (super 81) Kr/ (super 85) Kr by ATTA. (super 81) Kr ages of the water samples, obtained by comparing their (super 81) Kr/Kr ratios with that of modern air, range from approximately 200 to approximately 1,000 ka. Ages increase with distance along the flowpath and correlate well with (super 36) Cl/Cl ratios.

The area, which lies within the headwaters of the Weber River, was the site of the 2002 Winter Olympics. The watershed is a former silver mining area with a legacy of heavy-metal contamination in waters and soils related to nearly 1,200 miles of mine tunnels, tailings dumps, and waste rock piles. Currently, six active CERCLIS sites are in the watershed, one site is proposed for the National Priorities List, and Silver Creek is listed on the state's 303(d) list for zinc and cadmium and is targeted for TMDL (total maximum daily load) development. Our objective is to use existing data to develop a watershed-based, hierarchical analysis and an integrated conceptual model, focused on groundwater, to aid in characterization of contaminant migration pathways from overlapping sources in the watershed. We characterized the complex, multiscale hydrogeology of the Upper Silver Creek Watershed area by using hierarchical systems analysis of multidisciplinary data. Existing data sources were used to quantify climate, vegetation, surface water, topography, anthropogenic activities, soils, geomorphology, geology, and geochemistry. The hydrogeologic units were delineated spatially from a 3-D geologic model of the area. Significant permeable layers or major conduits for groundwater flow were identified, and hydrogeologic properties of these units were estimated by using available data. The hydrogeologic framework was then displayed as a solid block model to visualize and analyze the watershed system. Both surface water and groundwater subsystems were characterized. Significant groundwater flow, discharge, and recharge areas--and the relationship of these areas to the surrounding terrain and areas of environmental impact--were assessed and interrelated, and a potentiometric surface involving the critical sites was interpreted. The results, which show how each contaminant site is related to the watershed-scale hydrologic system, enable area stakeholders to reassess each site with respect to the whole hydrologic system. The analysis will allow a comprehensive, complex mathematical model to be constructed for future management and decision making.

However, the low-energy x-ray and electron probes require vacuum environment, and are completely inaccessible, blocked by the pressure vessels for high-pressure studies, as the soft x-ray and electron beams. Synchrotron inelastic x-ray scattering (IXS) (also called x-ray Raman) spectroscopy, is capable of penetrating high pressure vessels and probing the bonding of samples at high-pressure in-situ. Although this technique was demonstrated almost forty years ago, it has only recently been successfully applied to ambient pressure studies. Compressed under ambient temperature, graphite undergoes a transition at approximately 17 GPa. The near K-edge spectroscopy of carbon using synchrotron x-ray inelastic scattering reveals that half of the pi-bonds between graphite layers convert to sigma-bonds while the other half remain as pi-bonds in the high-pressure form. The x-ray diffraction pattern of the high-pressure form, using He as a pressure transmitting medium, is consistent with a distorted graphite structure in which bridging carbon atoms between graphite layers pair and form sigma-bonds, while the non-bridging carbon atoms remain unpaired with dangling pi-bonds. The high-pressure form is superhard, capable of indenting cubic diamond single crystals.

Facies associated with various glacial sedimentological settings may have very short lateral correlation distances. Deposits are later affected by ice readvances, by soil formation processes in-between advances, and by fracturing of fine-grained materials. Because of the nature of this depositional setting, a hydrogeological conceptual model for a glaciated terrain may therefore have a high degree of uncertainty at most scales of study. Of importance in hydrogeological analyses is that the properties, such as hydraulic conductivity, of the subsurface vary dramatically, and flaws in conceptual models may lead to inaccurate or inappropriate numerical flow models. Drilling data are typically an abundant source of subsurface information at groundwater contaminant or water resources study areas. These stratigraphic data provide an important means of initializing or refining a site conceptual model, yet hydrostratigraphic correlation may be complicated by the distances between boreholes. We have conducted hydrogeological analyses of several Midwestern study areas that differ in their glacial geologic settings and in the type and density of available drilling data. Techniques include data visualization, geostatistical analyses, and flow modeling. While some sites may be adequately characterized using traditional cross sections, understanding of more complex sedimentary associations requires a combination of quantitative approaches.

It contains approximately 50,000 km (super 3) of groundwater in a thick (up to 3,000 m) sandstone formation with thin interbedded shales. Residence times from 2 X 10 (super 4) -10 (super 6) a are suggested by aquifer hydrodynamics. The hydrology is complex and provides a good test for the robustness of the (super 36) Cl method of groundwater dating. In this study, about 30 groundwater samples from relatively deep (200-1200 m) wells in major oasis areas and shallow (<200 m) wells in the Lake Nasser and Toshka Canal areas were collected and analyzed for chemistry, delta (super 37) Cl, (super 36) Cl, and other stable and radiogenic isotopes. Chloride concentrations range from 21 to 394 ppm and decrease with increasing depth; this is typical for arid environments. Values of delta (super 37) Cl (SMOC) range from -1.16 to +0.51, indicating at least two chloride sources. Processes capable of producing variable delta (super 37) Cl are considered, including diffusion of Cl from saline pore fluids within aquicludes and halite precipitation-dissolution in the vadose zone. (super 36) Cl/Cl ratios range from 16-228 X 10 (super -15) . The data indicate that water from the deeper portions of the aquifer has a single, meteoric source of Cl and can be dated accurately by (super 36) Cl, showing a systematic increase in residence time of 4 X 10 (super 5) a down gradient. Samples from shallow wells have higher Cl (super -) concentrations, variable delta (super 37) Cl values, and generally higher (super 36) Cl activities than those from deeper wells, indicating transient local recharge of Cl-enriched surface waters. Numerical simulations of groundwater flow and chloride transport (including (super 36) Cl) in the aquifer indicate that baseflow from remote recharge areas occupies the deeper portions of the aquifer and follows the contour of the piezometric surface, whereas transient local recharge events influence the chemistry and isotopic characteristics of the shallower portions of the aquifer.

Egypt and other arid and semi-arid countries have adopted aggressive policies to capture surface water resources for reclamation of desert land. The Aswan High Dam, constructed in Egypt in 1964-1968, created the world's second largest artificial lake, Lake Nasser. Recently, as the reservoir has approached maximum storage capacity, several new lake reservoirs (Tushka Lakes) have developed in the lowlands west of Lake Nasser. Using a groundwater flow model, we investigated the dynamic change of the Nubian aquifer related to the development of Lake Nasser and the Tushka Lakes. To fully capture interactions between the surface and groundwater in the study area, the model domain included the area covered by the entire Lake Nasser in Egypt and Sudan, the Tushka Lakes, and their surroundings. The stages and the temporal variations (1967-2002) in the areal extent of the lakes under investigation were extracted from CORONA, Landsat TM, and DTED data and from recorded (1967-2000) surface water levels for Lake Nasser. The topography of the area now covered by water in Lake Nasser was estimated from (1) the areal extent of Lake Nasser in 1967 (CORONA) and 1972 (MSS), (2) DTED acquired in 1989, and (3) historic lake levels. Transient simulations suggest that the Nubian aquifer, a fossil groundwater reservoir, is significantly affected by recharge from Lake Nasser and the Tushka Lakes. To date, the recharge from Lake Nasser to the aquifer amounts to 10 (super 9) m (super 3) . After the lake reached maximum storage capacity, annual recharge decreased from 10 (super 7) m (super 3) /yr in 1996 to 10 (super 6) m (super 3) /yr in 2002. The trend of decreasing recharge is consistent with the gradual reduction of hydraulic gradient between the lake stage and the groundwater level in the Nubian aquifer. Since 1998 excess water in Lake Nasser has been routed through existing flood diversion to the Tushka Lakes. The recharge from these lakes to the Nubian aquifer has been rising (10 (super 5) m (super 3) /yr in 1998 to 10 (super 6) m (super 3) /yr in 2002); currently, recharge from the Tushka Lakes approximates recharge from Lake Nasser. Continuous encroachment of Lake Nasser water onto the lowlands could increase opportunities for sustainable use of fossil water of the Nubian aquifer, now being replenished by Lake Nasser.

X-ray reflectivity data demonstrate a high degree of structural similarity between these two orthoclase-water interfaces. Both interfacial structures include cleavage along the plane of minimal bond breakage resulting in surfaces terminated by non-bridging oxygens; structured water within 5 Aa of the orthoclase surface (consisting of adsorbed species at the surface and layered water above the surface), with a featureless water profile beyond 5 Aa; substitution of outermost K (super +) ions by an oxygen containing species (presumably H (sub 3) O (super +) ); and small structural displacements of the near surface atoms. The interfacial water structure, in comparison with recent results for other mineral-water interfaces, is intermediate between the minimal structure found at calcite-, barite-, and quartz-water interfaces and the more extensive structure found at the muscovite-water interface.

Like other arid and semi-arid nations, Egypt faces demand for development of new agricultural lands to support its increasing population. Overflow of Lake Nasser through a natural flood diversion in Egypt's southwestern desert has formed several new lakes that represent a newly available resource. We are delineating and simulating the natural development of Tushka Lakes resulting from rerouting of excess water from Lake Nasser, as well as projecting the future trend of lake growth. The past gradual formation of the Tushka Lakes, changes in lake extent, and lake stages were analyzed by using a series of Landsat TM, MODIS, ASTER, and shuttle images as well as DTED, and ASTER derived elevation data. The first lake, which emerged in 1998 on the Tushka depression west of Lake Nasser, covered an area of 400 km (super 2) , with a lake stage 172 m above mean sea level (AMSL). In 2000, excess water from Lake Nasser spread farther west, forming three additional lakes across a lowland area of 750 km (super 2) , with lake stages decreasing from east to west (162 m AMSL at the second lake to 147 m at the fourth lake). A recently developed fifth lake to the northwest has a lake stage of 144 m AMSL. All five newly developed Tushka lakes cover a total area of 1,300 km (super 2) , which is more than 20% of the area of Lake Nasser at maximum capacity. The surface water model was constructed and calibrated by adjusting routing parameters against lake stages identified for 1998-2002. The simulation based on the calibrated model suggests that lakes will continue to develop northwestward, toward a large depression including the Darb El-Arbeain area and the southern Kharga Oasis area, bounded by escarpment on the west. Further development of new lakes will generate significant recharge of fresh water to fossil groundwater in the underlying Nubian aquifer and will provide excellent water resources to the Darb El-Arbeain and the southern Kharga Oasis areas in the southwestern desert of Egypt.

The mobility of Np is difficult to predict in part due to its uncertain sorption behavior in geologic systems. In this study, we measured Np adsorption onto a common Gram-positive soil bacterium, Bacillus subtilis. We performed batch adsorption experiments with a 1 ppm Np(V) solution in contact with bacteria as a function of pH, from 2.5 to 8, and as a function of ionic strength, at 0.1M and 0.001M NaClO (sub 4) . Np adsorption exhibits an inverse relationship with ionic strength, and in general, adsorption increases with increasing pH. For example, at pH values of 4 and 8 in the 0.001 M ionic strength system, we measured 22% and 55% removal of the total Np from solution, while at those same pH values in the 0.1 M ionic strength system, Np adsorption was 3% and 17%, respectively. We model the adsorption reaction using a surface complexation approach to yield Np-bacterial surface stability constants. The 0.1 M data only require one bacterial surface complexation reaction (neptunyl-carboxylate) for the best fit: R-COO (super -) + NpO (sub 2) (super +) = R-COO-NpO (sub 2) (super +) (log K = 1.55). Two separate adsorption reactions are needed to account for the increase in adsorption due to the decrease in ionic strength. The two site model invokes neptunyl binding onto a deprotonated carboxyl and onto a neutral phosphoryl group: R-COO (super -) + NpO (sub 2) (super +) = R-COO-NpO (sub 2) (log K = 2.12) and R-POH + NpO (sub 2) (super +) = R-POH-NpO (sub 2) (super +) (log K = 9.05). Our calculated neptunyl-bacterial surface stability constants are consistent with values predicted using the correlation estimation approach from Fein et al. (2001), further indicating that the binding of cations onto bacterial surfaces is largely determined by the electrostatic and chemical properties of the cations. The magnitude of the stability constants indicates that neptunyl binding onto the bacterial surface is considerably weaker than adsorption involving metals such as Cd and Pb, and is similar to metals such as Ca. The calculated stability constants from this study may be integrated into geochemical models to help determine the effect of Np adsorption on the mobility and fate of Np in bacteria-water-rock systems.

Emissions are estimated for all major anthropogenic sources, including biomass burning, in 64 regions of Asia. We estimate total Asian emissions as follows: 34.3 Tg SO sub(2), 26.8 Tg NO sub(x), 9870 Tg CO sub(2), 279 Tg CO, 107 Tg CH sub(4), 52.2 Tg NMVOC, 2.54 Tg black carbon (BC), 10.4 Tg organic carbon (OC), and 27.5 Tg NH sub(3). In addition, NMVOC are speciated into 19 subcategories according to functional groups and reactivity. Thus we are able to identify the major source regions and types for many of the significant gaseous and particle emissions that influence pollutant concentrations in the vicinity of the TRACE-P and ACE- Asia field measurements. Emissions in China dominate the signature of pollutant concentrations in this region, so special emphasis has been placed on the development of emission estimates for China. China's emissions are determined to be as follows: 20.4 Tg SO sub(2), 11.4 Tg NO sub(x), 3820 Tg CO sub(2), 116 Tg CO, 38.4 Tg CH sub(4), 17.4 Tg NMVOC, 1.05 Tg BC, 3.4 Tg OC, and 13.6 Tg NH sub(3). Emissions are gridded at a variety of spatial resolutions from 1 degree x 1 degree to 30 s x 30 s, using the exact locations of large point sources and surrogate GIS distributions of urban and rural population, road networks, landcover, ship lanes, etc. The gridded emission estimates have been used as inputs to atmospheric simulation models and have proven to be generally robust in comparison with field observations, though there is reason to think that emissions of CO and possibly BC may be underestimated. Monthly emission estimates for China are developed for each species to aid TRACE-P and ACE-Asia data interpretation. During the observation period of March/April, emissions are roughly at their average values (one twelfth of annual). Uncertainties in the emission estimates, measured as 95% confidence intervals, range from a low of plus or minus 16% for SO sub(2) to a high of plus or minus 450% for OC.

This reaction permits the synthesis of ribose from other sugars, as well as the recycling of sugars from nucleotide breakdown. Two unrelated types of enzyme can catalyze the reaction. The most common, RpiA, is present in almost all organisms (including Escherichia coli), and is highly conserved. The second type, RpiB, is present in some bacterial and eukaryotic species and is well conserved. In E.coli, RpiB is sometimes referred to as AlsB, because it can take part in the metabolism of the rare sugar, allose, as well as the much more common ribose sugars. We report here the structure of RpiB/AlsB from E.coli, solved by multi-wavelength anomalous diffraction (MAD) phasing, and refined to 2.2A resolution. RpiB is the first structure to be solved from pfam02502 (the RpiB/LacAB family). It exhibits a Rossmann-type alpha beta alpha -sandwich fold that is common to many nucleotide-binding proteins, as well as other proteins with different functions. This structure is quite distinct from that of the previously solved RpiA; although both are, to some extent, based on the Rossmann fold, their tertiary and quaternary structures are very different. The four molecules in the RpiB asymmetric unit represent a dimer of dimers. Active-site residues were identified at the interface between the subunits, such that each active site has contributions from both subunits. Kinetic studies indicate that RpiB is nearly as efficient as RpiA, despite its completely different catalytic machinery. The sequence and structural results further suggest that the two homologous components of LacAB (galactose-6-phosphate isomerase) will compose a bi-functional enzyme; the second activity is unknown.

Asymmetries should be manifested in the clustering of bed thicknesses and other stratigraphic properties. Hemispheric asymmetry should not exist in an ice-free world. To demonstrate the concept, this paper establishes the foundations for the hypothesis and presents the results of a statistical analysis of the synthetic stratigraphy of a tropical monsoonal area.

The carbon number distribution of BAQCs indicates a biological origin. These compounds were observed but not identified in previous studies of 2.0 billion- to 2.2 billion-year-old metasediments and were commonly misidentified in other sediment samples, indicating that BAQCs are widespread in the geological record. The source organisms of BAQCs are unknown, but their paleobiogeographic distribution suggests that they have an affinity for sulfides and might be nonphotosynthetic sulfide oxidizers.

A survey of national, regional, and international publications on biomass burning is conducted to yield consensus estimates of 'typical' (i.e. non-year-specific) estimates of open burning (excluding biofuels). We conclude that 730 Tg of biomass are burned in a typical year from both anthropogenic and natural causes. Forest burning comprises 45% of the total, the burning of crop residues in the field comprises 34%, and 20% comes from the burning of grassland and savanna. China contributes 25% of the total, India 18%, Indonesia 13%, and Myanmar 8%. Regionally, forest burning in Southeast Asia dominates. National, annual totals are converted to daily and monthly estimates at 1 degree x 1 degree spatial resolution using distributions based on AVHRR fire counts for 1999-2000. Several adjustment schemes are applied to correct for the deficiencies of AVHRR data, including the use of moving averages, normalization, TOMS Aerosol Index, and masks for dust, clouds, landcover, and other fire sources. Good agreement between the national estimates of biomass burning and adjusted fire counts is obtained (R super(2) = 0.71-0.78). Biomass burning amounts are converted to atmospheric emissions, yielding the following estimates: 0.37 Tg of SO sub(2), 2.8 Tg of NO sub(x), 1100 Tg of CO sub(2), 67 Tg of CO, 3.1 Tg of CH sub(4), 12 Tg of NMVOC, 0.45 Tg of BC, 3.3 Tg of OC, and 0.92 Tg of NH sub(3). Uncertainties in the emission estimates, measured as 95% confidence intervals, range from a low of plus or minus 65% for CO sub(2) emissions in Japan to a high of plus or minus 700% for BC emissions in India.

AN - 73658926; 13678660 AB - We developed an in vivo model for cadmium-induced bone loss in which mice excrete bone mineral in feces beginning 8 h after cadmium gavage. Female mice of three strains [CF1, MTN (metallothionein-wild-type), and MT1,2KO (MT1,2-deficient)] were placed on a low-calcium diet for 2 weeks. Each mouse was gavaged with 200 microg Cd or vehicle only. Fecal calcium was monitored daily for 9 days, beginning 4 days before cadmium gavage, to document the bone response. For CF1 mice, bones were taken from four groups: +/- Cd, 2 h after Cd and +/- Cd, 4 h after Cd. MTN and MT1,2KO strains had two groups each: +/-Cd, 4 h after Cd. PolyA+ RNA preparations from marrow-free shafts of femura and tibiae of each +/- Cd pair were submitted to Incyte Genomics for microarray analysis. Fecal Ca results showed that bone calcium excreted after cadmium differed for the three mouse strains: CF1, 0.24 +/- 0.08 mg; MTN, 0.92 +/- 0.22 mg; and MT1,2KO, 1.7 +/- 0.4 mg. Gene array results showed that nearly all arrayed genes were unaffected by cadmium. However, MT1 and MT2 had Cd+/Cd- expression ratios >1 in all four groups, while all ratios for MT3 were essentially 1, showing specificity. Both probes for MAPK 14 (p38 MAPK) had expression ratios >1, while no other MAPK responded to cadmium. Vacuolar proton pump ATPase and integrin alpha v (osteoclast genes), transferrin receptor, and src-like adaptor protein genes were stimulated by Cd; other src-related genes were unaffected. Genes for bone formation, stress response, growth factors, and signaling molecules showed little or no response to cadmium. Results support the hypothesis that Cd stimulates bone demineralization via a p38 MAPK pathway involving osteoclast activation.

These analyses are challenging in that the grains are very small, the largest being perhaps a few microns in diameter, and contain only trace concentrations of heavy elements, generally on the order of ppm. In addition, isotopic analysis requires the suppression of isobaric interferences. We describe a unique instrument, based on resonant ionization mass spectrometry, that has successfully characterized such grains for the past several years, and report on some recent upgrades that significantly enhance the instrumental capabilities. The fundamental principles and operational details are discussed, along with illustrative results and plans for future modifications.

Mainstream SiC grains are enriched in s-process barium and show a spread in isotopic composition from solar to dominantly s-process. In the relatively coarse grain size fraction analyzed, there are large grain-to-grain variations of barium isotopic composition. Comparison of single grain data with models of nucleosynthesis in asymptotic giant branch (AGB) stars indicates that the grains most likely come from low mass carbon-rich AGB stars (1.5 to 3 solar masses) of about solar metallicity and with approximately solar initial proportions of r- and s-process isotopes. Measurements of single grains imply a wide variety of neutron-to-seed ratios, in agreement with previous measurements of strontium, zirconium and molybdenum isotopic compositions of single presolar SiC grains.

This triplet energy is transferred from P to C via the bacteriochlorophyll monomer BB. Using time-resolved electron paramagnetic resonance (TREPR), we have examined the temperature dependence of the rates of this triplet energy transfer reaction in the RC of three wild-type species of purple nonsulfur bacteria. Species-specific differences in the rate of transfer were observed. Wild-type Rhodobacter capsulatus RCs were less efficient at the triplet transfer reaction than Rhodobacter sphaeroides RCs, but were more efficient than Rhodospirillum rubrum RCs. In addition, RCs from three mutant strains of R. capsulatus carrying substitutions of amino acids near P and BB were examined. Two of the mutant RCs showed decreased triplet transfer rates compared with wild-type RCs, whereas one of the mutant RCs demonstrated a slight increase in triplet transfer rate at low temperatures. The results show that site-specific changes within the RC of R. capsulatus can mimic interspecies differences in the rates of triplet energy transfer. This application of TREPR was instrumental in defining critical energetic and coupling factors that dictate the efficiency of this photoprotective process.

However, structure alone is often insufficient to deduce the specific biochemical function of a protein. Here we determined the function for a protein using a strategy that integrates structural and bioinformatics data with parallel experimental screening for enzymatic activity. BioH is involved in biotin biosynthesis in Escherichia coli and had no previously known biochemical function. The crystal structure of BioH was determined at 1.7 Aa resolution. An automated procedure was used to compare the structure of BioH with structural templates from a variety of different enzyme active sites. This screen identified a catalytic triad (Ser super(82), His super(235), and Asp super(207)) with a configuration similar to that of the catalytic triad of hydrolases. Analysis of BioH with a panel of hydrolase assays revealed a carboxylesterase activity with a preference for short acyl chain substrates. The combined use of structural bioinformatics with experimental screens for detecting enzyme activity could greatly enhance the rate at which function is determined from structure.

AN - 73436914; 12875393 AB - Green rusts (GRs), mixed iron(II)/iron(III) hydroxide minerals found in many suboxic environments, have been shown to reduce a range of organic and inorganic contaminants, including several chlorinated hydrocarbons. Many studies have demonstrated the catalytic activity of transition metal species in the reduction of chlorinated hydrocarbons, suggesting the potential for enhanced reduction by GR in the presence of an appropriate transition metal catalyst. Reductive dechlorination of carbon tetrachloride (CT) was examined in aqueous suspensions of GR amended with Ag(I), Au(III), or Cu(II). The CT reduction rates were greatly increased for systems amended with Cu(II), Au(III), and Ag(I) (listed in order of increasing rates) relative to GR alone. Observed intermediates and products included chloroform, dichloromethane, chloromethane, methane, acetylene, ethene, ethane, carbon monoxide, tetrachloroethene, and various nonchlorinated C3 and C4 compounds. Product distributions for the reductive dechlorination of CT were highly dependent on the transition metal used. A reaction pathway scheme is proposed in which CT is reduced primarily to methane and other nonchlorinated end products, largely through a series of one-electron reductions forming radicals and carbenes/carbenoids. Recently, X-ray absorption fine structure analysis of aqueous GR suspensions amended with Ag(I), Au(III), or Cu(II) showed that the metals were reduced to their zerovalent forms. A possible mechanism for CT reduction is the formation of a galvanic couple involving the zerovalent metal and GR, with reduction of CT occurring on the surface of the metal and GR serving as the bulk electron source. The enhanced reduction of CT by GR suspensions amended with Ag(I), Au(III), or Cu(II) may prove useful in the development of improved materials for remediation of chlorinated organic contaminants.

The solid, a synthetic (super 57) Fe-enriched Fe(III)-bearing pyroaurite-like phase having terephthalate (TA) in the interlayer [Mg (sub 3) Fe(OH) (sub 8) (TA) (sub 0.5) .2H (sub 2) O], was reduced by Na (sub 2) S (sub 2) O (sub 4) and then reoxidized by K (sub 2) Cr (sub 2) O (sub 7) by means of a novel flow-through cell. Synchrotron Mossbauer spectra were collected in the time domain at 30-s intervals. Integration of the intensity obtained during a selected time interval in the spectra allowed sensitive determination of Fe(II) content as a function of reaction time. Analysis of reaction end member specimens by both the synchrotron technique and conventional Mossbauer spectroscopy yielded comparable values for Mossbauer parameters such as center shift and Fe(II)/Fe(III) area ratios. Slight differences in quadrupole splitting values were observed, however. A reactive diffusion model was developed that fit the experimental Fe(II) kinetic data well and allowed the extraction of second-order rate constants for each reaction. Thus, in addition to rapidly collecting high quality Mossbauer data, the synchrotron technique seems well suited for aqueous rate experiments as a result of the penetrating power of 14.4 keV X-rays and high sensitivity to Fe valence state.

Here we report the temperature dependence of the cation distribution in the 4-2 spinel synthetic qandilite (Mg (sub 2) TiO (sub 4) ) from in situ time-of-flight neutron powder diffraction experiments to 1416 degrees C. At room temperature, Mg (sub 2) TiO (sub 4) is confirmed to have completely inverse cation distribution, with Ti atoms occupying half the octahedrally coordinated cation sites. Cation disordering becomes observable above about 900 degrees C, with 4% of the Ti occupying the tetrahedral site by 1416 degrees C. The rate of reordering on cooling is fast, such that high-temperature disorder is not preserved on cooling to room temperature.

While the long-term depositional sink for some new particles entering the lake, either from rivers or shoreline erosion, has been well documented, the aggregate time scale of the processes by which these particles move from source to sink is not well quantified. These relatively "new" particles may undergo numerous episodes of resuspension and redeposition before making their way through the coastal margin and entering the long term focusing processes active in the depositional basins of the lake. These episodic events can be large in scale and magnitude, resuspending as much or more material than is permanently deposited in the lake on an annual basis. Th-234, a particle reactive radionuclide with a 24 day half-life, would appear to be well suited as a tracer for following rapid particle movement, particle residence times in the overlying water, and alongshore transport processes. The remotely operated vehicle (ROV) deployed technique for collection of surface sediments residing in nondepositional (hard bottom) lakebeds and some preliminary time series results for transient excess Th-234 inventories in the nearshore of Lake Michigan are described.

Our goal has been to collect field data necessary for development, verification, and improvement of the algorithms used for retrieving biological and sedimentological parameters over a wide range of water conditions. In addition to using conventional regression approaches that relate the concentrations of optically active properties to some empirical function of water-leaving radiances, we have been exploring the use of Bayesian statistical methods in concert with hydrodynamic and sediment transport modeling to supplement our sparse dataset and to establish probability distributions for the parameter values. Based on analysis of data collected in southern Lake Michigan during the Episodic Events Great Lakes Experiment (EEGLE) project, the combined Bayesian-modeling method seems especially promising for establishing an algorithm for using satellite data to retrieve suspended sediment concentrations. Transferring the method to develop a more robust chlorophyll retrieval algorithm also should be feasible.

Because of its simplicity, the scalar model is easily incorporated into more complex, multi-dimensional simulation systems and is attractive from both computational and conceptual viewpoints. Spatial dependence may be modeled by varying the parameters describing the sediment response to the imposed flow; much of our field work has been aimed at understanding the relationship between these model parameters and easily measured properties of the local sediments. Although our results are qualitatively reasonable, we would like to improve the model's ability to represent subtle, but realistic, variations in sediment type. To determine the quantitative limitations of our simple modeling approach and our similarly uncomplicated measurement methods, we have been using Bayesian statistics and a Lagrangian particle model to examine our scalar model structure, its sensitivity to variation of its parameters, and changes in the model representation of the important physical processes. We find that the ability to discriminate between different sediment types may depend on the form used for the erosion flux more than on the method used to determine the parameter values.

Drill cores from the shallow portion of the deposit preserve a sharp Fe redox front defined by Fe(III) oxide staining. This front is located near a discontinuity in U mineralogy with U(IV) assemblages (e.g. coffinite, uraninite) on the reducing side, and U(VI) assemblages on the oxidizing side. The discontinuity in U mineralogy does not, however, represent a major discontinuity in whole rock U concentrations, with sample groups from both oxidized and reduced sides of the front generally ranging from 500 to 1000 ppm. This observation suggests that the volume of shallow bedrock associated with the deposit has not lost significant amounts of U during the oxidation and incipient chemical weathering. The precipitation of Ba uranyl phosphate (Ba meta-autunite) is responsible for U retention within this zone. Ground waters sampled from the weathered bedrock aquifer associated with the deposit contain less than 15 mu g l super(-1) dissolved U. This suggests that the low solubility of the Ba meta- autunite limits U concentrations to values lower than the US-EPA maximum contaminant level of 30 mu g l super(-1). Ground water speciation and mineral saturation calculations show that, in addition to Eh and pH, the most important factor controlling this U fixation process is the activity ratio of dissolved phosphate to dissolved carbonate. Experimental results suggest that, at the Coles Hill site, the oxidation of U(IV) to U(VI) and subsequent precipitation of uranyl phosphate occurs rapidly (time scale of weeks) relative to ground water transport (e.g. 20 m/a). Furthermore, based on the rate of downward migration of the redox front, it is estimated that the oldest U(VI) phosphate assemblages associated with the Coles Hill U deposit have been stable for up to 150 ka. These observations have important implications for the design and long term performance assessment of phosphate-based stabilization and reactive barrier techniques.

The SlyA family, which includes SlyA, Rap, Hor, and RovA proteins, is widely distributed in bacterial and archaeal genomes. Current evidence suggests that SlyA-like factors act as repressors, activators, and modulators of gene transcription. These proteins have been shown to up- regulate the expression of molecular chaperones, acid-resistance proteins, and cytolysin, and down-regulate several biosynthetic enzymes. The structure of SlyA from Enterococcus faecalis, determined as a part of an ongoing structural genomics initiative (www.mcsg.anl.gov), revealed the same winged helix DNA-binding motif that was recently found in the MarR repressor from Escherichia coli and the MexR repressor from Pseudomonas aeruginosa, a sequence homologue of MarR. Phylogenetic analysis of the MarR/SlyA family suggests that Sly is placed between the SlyA and MarR subfamilies and shows significant sequence similarity to members of both subfamilies.

AN - 73339737; 12785508 AB - Certain petroleum production activities cause naturally occurring radioactive materials (NORM) to accumulate in concentrations above natural background levels, making safe and cost-effective management of such technologically enhanced NORM (TENORM) a key issue for the petroleum industry. As a result, both industry and regulators are interested in identifying cost-effective disposal alternatives that provide adequate protection of human health and the environment One such alternative, currently allowed in Michigan with restrictions, is the disposal of TENORM wastes in nonhazardous waste landfills. The disposal of petroleum industry wastes containing radium-226 (Ra-226) in nonhazardous landfills was modeled to evaluate the potential radiological doses and health risks to workers and the public. Multiple scenarios were considered in evaluating the potential risks associated with landfill operations and the future use of the property. The scenarios were defined, in part, to evaluate the Michigan policy; sensitivity analyses were conducted to evaluate the impact of key parameters on potential risks. The results indicate that the disposal of petroleum industry TENORM wastes in nonhazardous landfills in accordance with the Michigan policy and existing landfill regulations presents a negligible risk to most of the potential receptors considered in this study.

Many types of data are generated during the course of proteome analysis, including graphic images of the protein profiles, flat files containing numeric data, spreadsheets for assimilating numeric data, and relational database tables for integrating data from multiple experiments. As part of a project to describe the proteomes of microbes of interest to the U.S. Department of Energy, a World-Wide Web-based interface has been developed for the display of protein profiles generated by two-dimensional gel electrophoresis. The web interface is capable of obtaining protein identifications on the fly, interrogating the quantitative data in the context of available genome sequence information, and relating the proteome data to existing metabolic pathway databases. Analysis of protein expression profiles is expedited, providing the capability to efficiently determine the gene locations for proteins modulated in abundance in response to different growth conditions and to locate the positions of the proteins within specific metabolic pathways.

AN - 73424335; 12806107 AB - Atmospheric chemistry is an important discipline for understanding air pollution and its impacts. This mini-review gives a brief history of air pollution and presents an overview of some of the basic photochemistry involved in the production of ozone and other oxidants in the atmosphere. Urban air quality issues are reviewed with a specific focus on ozone and other oxidants, primary and secondary aerosols, alternative fuels, and the potential for chlorine releases to amplify oxidant chemistry in industrial areas. Regional air pollution issues such as acid rain, long-range transport of aerosols and visibility loss, and the connections of aerosols to ozone and peroxyacetyl nitrate chemistry are examined. Finally, the potential impacts of air pollutants on the global-scale radiative balances of gases and aerosols are discussed briefly.

Among other reactions, P450s catalyze the site-specific oxidation of the precursors to macrolide antibiotics in the genus Streptomyces introducing regiochemical diversity into the macrolide ring system, thereby significantly increasing antibiotic activity. Developing effective uses for Streptomyces enzymes in biosynthetic processes and bioremediation requires identification and engineering of additional monooxygenases with activities toward a diverse array of small molecules. To elucidate the molecular basis for substrate specificity of oxidative enzymes toward macrolide antibiotics, the x-ray structure of CYP154C1 from Streptomyces coelicolor A3(2) was determined. Relocation of certain common P450 secondary structure elements, along with a novel structural feature involving an additional beta -strand transforming the five-stranded beta -sheet into a six-stranded variant, creates an open cleft-shaped substrate-binding site between the two P450 domains. High sequence similarity to macrolide monooxygenases from other microbial species translates into catalytic activity of CYP154C1 toward both 12- and 14-membered ring macrolactones in vitro.

Experimental observations show activity of only one of them-the A branch-in wild-type bacterial RCs. In a mutant RC, we now demonstrate that electron transfer can occur along the entire, normally inactive B-branch pathway to reduce the terminal acceptor Q sub(B) on the time scale of nanoseconds. The transmembrane charge-separated state P super(+)Q super(-) sub(B) is created in this manner in a Rhodobacter capsulatus RC containing the F(L181)Y-Y(M208)F-L(M212)H-W(M250)V mutations (YFHV). The W (M250)V mutation quantitatively blocks binding of Q sub(A), thereby eliminating Q sub(B) reduction via the normal A-branch pathway. Full occupancy of the Q sub(B) site by the native UQ sub(10) is ensured (without the necessity of reconstitution by exogenous quinone) by purification of RCs with the mild detergent, Deriphat 160-C. The lifetime of P super(+)Q super(-) sub(B) in the YFHV mutant RC is >6 s (at pH 8.0, 298 K). This charge-separated state is not formed upon addition of competitive inhibitors of Q sub(B) binding (terbutryn or stigmatellin). Furthermore, this lifetime is much longer than the value of similar to 1-1.5 s found when P super(+)Q super(-) sub(B) is produced in the wild-type RC by A-side activity alone. Collectively, these results demonstrate that P super(+)Q super(-) sub(B) is formed solely by activity of the B-branch carriers in the YFHV RC. In comparison, P super(+)Q super(-) sub(B) can form by either the A or B branches in the YFH RC, as indicated by the biexponential lifetimes of similar to 1 and similar to 6-10 s. These findings suggest that P super(+)Q super(-) sub(B) states formed via the two branches are distinct and that P super(+)Q super(-) sub(B) formed by the B side does not decay via the normal (indirect) pathway that utilizes the A-side cofactors when present. These differences may report on structural and energetic factors that further distinguish the functional asymmetry of the two cofactor branches.

AN - 52016936; 2003-018492 AB - The Cretaceous thermal maximum was a major turning point in the history of Earth's climate. This interval of peak warmth in the Turonian has been attributed to very high atmospheric pCO (sub 2) resulting from rapid outgassing rates, although crustal cycling rates peaked in the Aptian-Albian interval. On the basis of coupled ocean-atmosphere model simulations of the middle Cretaceous, we hypothesize that the formation of an Atlantic gateway could have contributed to the Cretaceous thermal maximum. Differences between prerifting and postrifting climate experiments demonstrate substantial regional oceanographic changes in the North and South Atlantic Basins that are consistent with oxygen isotopic evidence used to infer a Cretaceous thermal maximum. The model results help reconcile the paleoclimate record inferred from foraminiferal delta (super 18) O with our understanding of climate dynamics and Cretaceous tectonism.

Similar work in low salinity, estuarine, and freshwater systems has not occurred primarily because the lower concentrations of both parent and daughter nuclides that are typical of these systems often render established methods for the analysis of (super 234) Th inadequate. The application of this radionuclide tracer technique to these systems, however, has great potential. To this end, we present a method for measuring low activities of (super 234) Th in relatively small samples (<200 l) using low background gas-flow proportional counters, a (super 229) Th yield monitor and empirical corrections for the interferences from real and apparent betas that are emitted by other thorium isotopes and their progeny. For samples with low (super 234) Th/ (super 228) Th activity ratios, we improve upon current beta counting methodologies that rely on immediate sample counting, weak beta absorption, or multiple beta counts so that, using the analytical approach outlined here, it should be possible to measure (super 234) Th activities (i) as low as 1.5 dpm/total sample, (ii) up to 2 weeks after radiochemical purification of thorium, and (iii) with only one sample count for alpha and beta activity.

The estimated rates of removal obtained from the (super 90) Sr- (super 90) Y disequilibrium showed good agreement with (a) measured rates of mass removal obtained from settling particle fluxes in sediment traps and the inventories of suspended material and (b) independently obtained removal coefficients for the scavenging behavior of two different isotopes of particle-reactive plutonium, present in the water column because of different processes. Because (super 90) Sr is widespread and readily measurable in freshwater systems as a result of fallout from nuclear weapons testing, the (super 90) Sr- (super 90) Y disequilibrium is a potentially valuable resource for examining particle dynamics in surface waters.

Although its structure is conserved, its primary sequence is highly divergent and gives rise to a plethora of distinct functions. Most structures deposited into the Protein Data Bank consist of the TIM barrel fold, and TIM barrel appears to be the most common fold in yeast. Nearly all TIM barrel proteins are enzymes, and so far, 15 distinct enzymatic functions have been assigned to TIM barrel containing proteins. (The exception, narbonin, has no known function.) Most commonly, their active sites are positioned within the beta alpha loops at the C-terminal end of the protein. TIM barrels are differentiated by auxiliary features such as location (and nature) of additional domains, identity of cofactor, number of ( beta alpha ) units, location of the barrel major axis, and are based on strand and shear number. In general, in all TIM barrels and most other protein folds the main-chain does not cross over (to form a knot), although protein topologies involving formation of a knot have been reported in proteins.

N1 - Last updated - 2012-06-07 ER - TY - JOUR T1 - Orthoclase dissolution kinetics probed by in situ X-ray reflectivity; effects of temperature, pH, and crystal orientation AN - 52015386; 2003-021719 AB - Initial dissolution kinetics at orthoclase (001) and (010) cleavage surfaces were measured for approximately 2 to 7 monolayers as a function of temperature using in situ X-ray reflectivity. The sensitivity of X-ray reflectivity to probe mineral dissolution is discussed, including the applicability of this approach for different dissolution processes and the range of dissolution rates ( approximately 10 (super -12) to 10 (super -6) mol/m (super 2) /sec) that can be measured. Measurements were performed at pH 12.9 for the (001) surface and at pH 1.1 for the (001) and (010) surfaces at temperatures between 46 and 83 degrees C. Dissolution at pH 12.9 showed a temperature-invariant process with an apparent activation energy of 65+ or -7 kJ/mol for the (001) cleavage surface consistent with previous powder dissolution results. Dissolution at pH 1.1 of the (001) and (010) surfaces revealed a similar process for both surfaces, with apparent activation energies of 87+ or -7 and 41+ or -7 kJ/mol, respectively, but with systematic differences in the dissolution process as a function of temperature. Longer-term measurements (five monolayers) show that the initial rates reported here at acidic pH are greater than steady-state rates by a factor of 2. Apparent activation energies at acidic pH differ substantially from powder dissolution results for K-feldspar; the present results bracket the value derived from powder dissolution measurements. The difference in apparent activation energies for the (001) and (010) faces at pH 1.1 reveals an anisotropy in dissolution kinetics that depends strongly on temperature. Our results imply a projected approximately 25-fold change in the ratio of dissolution rates for the (001) and (010) surfaces between 25 and 90 degrees C. The dissolution rate of the (001) surface is higher than that of the (010) surface above 51 degrees C and is projected to be lower below this temperature. These results indicate clearly that the kinetics and energetics of orthoclase dissolution at acidic pH depend on crystal orientation. This dependence may reflect the different manifestation of the Al-Si ordering between the T1 and T2 tetrahedral sites at these two crystal faces and can be rationalized in terms of recent theoretical models of mineral dissolution.

These compounds are ideal for studying FOH solid solution in minerals because natural members of the series generally show little deviation from the ideal composition. In this study, we used powder and single-crystal neutron diffraction and solid-state (super 6) Li MAS, CP MAS, and REDOR NMR techniques to study the effect of FOH substitution on the series. Lattice parameters refined from single-crystal neutron diffraction data show increasing b and decreasing a, c, and V with increasing F/(F+OH). The volume is highest for the OH end-member because of the presence of an additional atom (H). The a and c parameters decrease with increasing F/(F+OH) because the O-H vector is close to the a-c plane and the Al-OH/F vectors are approximately parallel to c. Lattice parameters refined from neutron powder diffraction patterns collected at lower T show that thermal contraction increases with F/(F+OH), presumably because the F anion takes up less space than the OH molecule. The results show that the OH/F position is always fully occupied. The H displacement ellipsoid shows little change with occupancy, which obviously corresponds negatively with increasing F/(F+OH). However, the Li displacement ellipsoid becomes extremely large and anisotropic with increasing F fraction. Most of the distortion is associated with the U (sub 3) eigenvalue, which lies between the c and c (super *) directions. U (sub eq) values corresponding to the Li atom show a greater reduction with decreasing temperature than the other atoms. The temperature dependence of Li is the same regardless of F content. Even when extrapolated to absolute zero the Li displacement ellipsoid is very large, which implies a large static disorder. At the montebrasite end of the series, there are five short Li-phi (phi = O, OH, F) distances and one very long Li-O4 bond. With increasing F content, the Li-O4 distance decreases and the Li-O3f distance increases, such that at the amblygonite end, the coordination is 4+2. The disorder in the Li site is obviously caused by the substitution of F for OH. The driving force is the loss of the hydrogen bond to O4, which causes the Li-O4 bond to strengthen and improves the bond valence to O4. The results show that the H atom position is imbedded within the distorted octahedral oxygen coordination of the Li atom. To represent the disorder better, we used a split Li site model. The results show that Li1 occupancy increases and the Li2 occupancy decreases with increasing F content, and that the Li1-Li2 distance is longer for intermediate compositions than for the end-members. The (super 6) Li MAS NMR experiments provide important structural information complementary to the neutron diffraction results. The spectra of samples in the amblygonite-montebrasite series show two well-resolved peaks, confirming the presence of Li disorder over two distinct sites, and highly resolved (super 6) Li MAS NMR spectra are obtained at the very high magnetic field strength of 18.8 T. The peaks at -0.3 ppm and -0.9 ppm were unambiguously assigned to the Li2(OH) and Li1(F) sites found in the neutron diffraction structures. The isotropic chemical shifts are consistent with the coordinations of these Li sites found in the neutron diffraction structures. The relative intensities of the two peaks across the series of samples reflect the varying F/(F+OH). In addition to confirming the assignments of the peaks, it is possible to measure H-Li2 and F-Li1 internuclear distances by (super 6) Li{ (super 1) H} and (super 6) Li{ (super 19) F} CP and REDOR NMR that are consistent with the corresponding distances from the neutron diffraction structures. The (super 6) Li{ (super 1) H} and (super 6) Li{ (super 19) F} CP and REDOR results indicate that the Li disorder is random throughout the crystals rather than over large domains, a conclusion that cannot be made from diffraction experiments. Variable temperature (super 6) Li MAS NMR spectra confirm that the disorder is static and there is no dynamic exchange involving F, OH, or Li. Each Li ion has access to only one of the two observed sites as determined by the presence of either OH or F in its immediate environment and there is no possibility of a dynamic exchange.

Most show solar system isotopic compositions; however, one is enhanced in the p-process isotopes (super 92) Mo and (super 94) Mo. This is the first such observation and may help to elucidate the astrophysical site of the p-process.

The working group is comprised of technical experts representing DOE national laboratories, the DOE Naval Reactors Program, and DOE contractors. The motivation behind preparing this handbook was to document and disseminate lessons learned and information accumulated from more than 20 years of experience by DOE and its contractors in preparing transport risk assessments that address the shipment of virtually all types of radioactive materials and wastes. The handbook is intended to serve as a primary source of information on conducting transport risk assessments for shipments of radioactive materials or wastes under both normal and accident conditions. The paper provides an overview of the information contained in the handbook. It should be recognised that development of radioactive materials transport risk assessment is an ongoing process, and that the analysis methods are regularly improved.

Methylation of a base in a specific DNA sequence protects DNA from nucleolytic cleavage by restriction enzymes recognizing the same DNA sequence. We have determined at 1.74 Aa resolution the crystal structure of a beta -class DNA MTase MboIIA (M super(.)MboIIA) from the bacterium Moraxella bovis, the smallest DNA MTase determined to date. M super(.)MboIIA methylates the 3' adenine of the pentanucleotide sequence 5'-GAAGA-3'. The protein crystallizes with two molecules in the asymmetric unit which we propose to resemble the dimer when M super(.)MboIIA is not bound to DNA. The overall structure of the enzyme closely resembles that of M super(.)RsrI. However, the cofactor-binding pocket in M super(.)MboIIA forms a closed structure which is in contrast to the open-form structures of other known MTases.

This enzyme plays essential roles in carbohydrate anabolism and catabolism; it is ubiquitous and highly conserved. The structure of RpiA from Escherichia coli was solved by multiwavelength anomalous diffraction (MAD) phasing, and refined to 1.5 Ae resolution (R factor 22.4%, R sub(free) 23.7%). RpiA exhibits an alpha / beta /( alpha / beta )/ beta / alpha fold, some portions of which are similar to proteins of the alcohol dehydrogenase family. The two subunits of the dimer in the asymmetric unit have different conformations, representing the opening/closing of a cleft. Active site residues were identified in the cleft using sequence conservation, as well as the structure of a complex with the inhibitor arabinose-5-phosphate at 1.25 A resolution. A mechanism for acid-base catalysis is proposed.

In this study, we investigated the physical spacing and nucleotide mismatch tolerance between capture and proximal chaperone detector probes that are required to achieve species-specific 16S rRNA detection for the dissimilatory metal and sulfate reducer 16S rRNAs. Microarray specificity was deduced by analyzing signal intensities across replicate microarrays with a statistical analysis-of-variance model that accommodates well-to-well and slide-to-slide variations in microarray signal intensity. Chaperone detector probes located in immediate proximity to the capture probe resulted in detectable, nonspecific binding of nontarget rRNA, presumably due to base-stacking effects. Species-specific rRNA detection was achieved by using a 22-nt capture probe and a 15-nt detector probe separated by 10 to 14 nt along the primary sequence. Chaperone detector probes with up to three mismatched nucleotides still resulted in species-specific capture of 16S rRNAs. There was no obvious relationship between position or number of mismatches and within- or between-genus hybridization specificity. From these results, we conclude that relieving secondary structure is of principal concern for the successful capture and detection of 16S rRNAs on planar surfaces but that the sequence of the capture probe is more important than relieving secondary structure for achieving specific hybridization.

Many of these deficiencies should have been foreseeable, and therefore preventable, at the time the remedy was selected. Analysis of successes and deficiencies noted in the CERCLA five-year reviews highlights the pivotal role that monitoring plans and land use controls have in ensuring remedy protectiveness. The analysis demonstrated that remedy protectiveness assessments and remedy modification justifications depend on robust site and remedy monitoring plans as well as on adequately developed conceptual site models. Comprehensive understanding and inferences regarding past, present, and future land and resource use at the remedy selection stage can enhance remedy protectiveness because stakeholders can determine if land use controls are necessary and if they can be implemented and enforced. The findings from this analysis of five-year reviews of remedy protectiveness are applicable to initial remedy selection decisions and subsequent enhancements of their effectiveness through time.

This technology requires random fragmentation and fluorescent labeling of target nucleic acids prior to hybridization. Radical- generating coordination complexes, such as 1,10-phenanthroline-Cu(II) (OP-Cu) and Fe(II)-EDTA (Fe-EDTA), have been commonly used as sequence nonspecific 'chemical nucleases' to introduce single-strand breaks in nucleic acids. Here we describe a new method based on these radical-generating complexes for random fragmentation and labeling of both single- and double-stranded forms of RNA and DNA. Nucleic acids labeled with the OP-Cu and the Fe-EDTA protocols revealed high hybridization specificity in hybridization with DNA microchips containing oligonucleotide probes selected for identification of 16S rRNA sequences of the Bacillus group microorganisms.We also demonstrated cDNA- and cRNA-labeling and fragmentation with this method. Both the OP-Cu and Fe-EDTA fragmentation and labeling procedures are quick and inexpensive compared to other commonly used methods. A column-based version of the described method does not require centrifugation and therefore is promising for the automation of sample preparations in DNA microchip technology as well as in other nucleic acid hybridization studies.

Using individuals of Achillea millefolium grown under field conditions in Michigan, USA, the hypothesis was tested that seed number was determined largely by plant biomass, while seed germination success depends on tissue nutrient concentrations. The impact was assessed of four biotic and abiotic factors on seed number and germination success: root competition, shoot competition, fertilizer, and removal of fungi by fungicide application. Using a path analysis, it was found that total plant biomass positively affected both seed number and germination success, while inclusion of other variables did not greatly affect the amount of variation the model was able to explain. Fertilizer and fungicide increased, while root and shoot competition decreased both seed number and germination. Fungicide applied to the maternal plant increased biomass but decreased tissue phosphorus concentrations. In species where germination responds to nutrient concentrations, the potential exists for opposing impacts of environmental treatments on different components of fitness. This study suggests that environmental impacts on seed number will outweigh impacts on germination success under field conditions, and that biomass is an adequate surrogate for fitness in herbaceous plants.

As such, they access a limited complement of genetic information and many independent restriction enzymes or probes are required to achieve statistical rigor and confidence in the resulting pattern of DNA fragments. Furthermore, statistical comparison of gel-based fingerprints is complex and nonstandardized. To overcome these limitations of gel-based microbial DNA fingerprinting, we developed a prototype, 47-probe microarray consisting of randomly selected nonamer oligonucleotides. Custom image analysis algorithms and statistical tools were developed to automatically extract fingerprint profiles from microarray images. The prototype array and new image analysis algorithms were used to analyze 14 closely related Xanthomonas pathovars. Of the 47 probes on the prototype array, 10 had diagnostic value (based on a chi-squared test) and were used to construct statistically robust microarray fingerprints. Analysis of the microarray fingerprints showed clear differences between the 14 test organisms, including the separation of X. oryzae strains 43836 and 49072, which could not be resolved by traditional gel electrophoresis of REP-PCR amplification products. The proof-of-application study described here represents an important first step to high-resolution bacterial DNA fingerprinting with microarrays. The universal nature of the nonamer fingerprinting microarray and data analysis methods developed here also forms a basis for method standardization and application to the forensic identification of other closely related bacteria.

The model obtains emission factors from the Biogenic Emission Inventory System (BEIS). This biogenic emissions model, combined with a dry deposition model, was applied with environmental variable values supplied by MM5 (the fifth-generation Mesoscale Model). The modeled temporal variations and spatial distributions of the surface emissions rates of isoprene, monoterpenes, and nitric oxide the eastern US agreed well with reported simulations, measurements, and inferences. Use of the satellite data generates considerable detail in the spatial patterns, high temporal resolution, and a smooth seasonal variation in the emission rates. The new biogenic emissions model was used with a photochemistry modeling system to infer ozone (O sub(3)) concentrations in the lower troposphere above the eastern United States for a two-day case in July 1995, which had O sub(3) episodes studied previously by the Ozone Transport Assessment Group. Compared to the results from the OTAG application of BEIS2, the satellite-data-derived isoprene emissions were slightly lower in the northeastern United States, which resulted in smaller values of O sub(3) concentration and were 3-4 times higher in southeastern mixed forests, which had little impact on O sub(3) except near strong NO sub(x) emission sources.

Bones from fos-deficient mice contain very few osteoclasts; src-/- bones contain osteoclasts that fail to activate. Fos-/- and src-/- mice develop osteopetrotic bones and their teeth do not erupt. These mice were used to determine if cadmium requires c-Fos or c-Src and secondarily functional osteoclasts to decrease bone mineral content. Mice heterozygous for fos deficiency were mated to produce fos-/- and fos+/o (wild-type) offspring. Pups were divided into four groups: fos+/o, Cd-; fos+/o, Cd+; fos-/-, Cd-; and fos-/-, Cd+. Cd+ pups received daily sc injections (50 mu g Cd/kg) on days 17-20 and Cd in drinking water thereafter (10 ppm, days 21-27; 20 ppm, days 27-50). An analogous protocol was followed mating mice heterozygous for src deficiency. For acute exposures, 50-day-old mice were placed on a low-calcium diet and given two sequential 100 mu g Cd doses by gavage, and feces were monitored for excretion of bone calcium. Continuous exposure results demonstrate that cadmium (1) significantly decreased bone calcium content (14-15%) and concentration (12-13%) in both fos+/o and fos-/- mice, (2) doubled multinucleated osteoclast-like cell number in fos-/- bones, and (3) stimulated tooth eruption in 40% of fos-/- mice. Cd gavage stimulated bone calcium excretion in both fos+/o and fos-/- mice. In contrast, cadmium had no effect on bones or teeth in src-/- mice. Results indicate that cadmium can decrease bone mineral via a c-Fos-independent pathway; however, c-Src is required for cadmium to stimulate bone remodeling and tooth eruption pathways.

GATases catalyze two separate reactions at two active sites, which are located either on a single polypeptide chain or on different subunits. In the glutaminase reaction, glutamine is hydrolyzed to glutamate and ammonia, which is added to an acceptor substrate in the synthase reaction. Imidazole glycerol phosphate synthase (IGPS) is a GATase that catalyzes the bifurcation step of the histidine and de novo purine biosynthetic pathways. In yeast, IGPS is a single polypeptide, whereas in bacteria IGPS activity is effected by a complex of a glutaminase subunit, HisH, and a synthase subunit, HisF. IGPS is a class I GATase, which is characterized by a Cys-His-Glu catalytic triad. IGPS is a potential target for antibiotic and herbicide development because the histidine pathway does not occur in mammals. Here, we present the crystal structure of the HisH protein from Thermotoga maritima (TmHisH), which complements the known structure of HisF from the same organism (TmHisF) [Protein Data Bank (PDB) ID 1THF] and HisF from Pyrobaculum aerophilum (PDB ID 1H5Y) and shows high structural similarity with the glutaminase domain of the recently determined structure of IGSP from yeast (HIS7) (PDB ID 1JVN).

Surface complexation modeling can be used to predict metal distributions in water-rock systems, and it has been used to quantify bacterial adsorption of metal cations. However, successful application of these models requires a detailed knowledge not only of the type of bacterial surface site involved in metal adsorption/desorption, but also of the binding geometry. Previous acid-base titrations of B. subtilis cells suggested that three surface functional group types are important on the cell wall; these groups have been postulated to correspond to carboxyl, phosphoryl, and hydroxyl sites. When the U(VI) adsorption to B. subtilis is measured, observed is a significant pH-independent absorption at low pH values (<3.0), ascribed to an interaction between the uranyl cation and a neutrally charged phosphoryl group on the cell wall. The present study provides independent quantitative constraints on the types of sites involved in uranyl binding to B. subtilis from pH 1.67 to 4.80. The XAFS results indicate that at extremely low pH (pH 1.67) UO (sub 2) (super 2+) binds exclusively to phosphoryl functional groups on the cell wall, with an average distance between the U atom and the P atom of 3.64+ or -0.01 Aa. This U-P distance indicates an inner-sphere complex with an oxygen atom shared between the UO (sub 2) (super 2+) and the phosphoryl ligand. The P signal at extremely low pH value is consistent with the UO (sub 2) (super 2+) binding to a protonated phosphoryl group, as previously ascribed. With increasing pH (3.22 and 4.80), UO (sub 2) (super 2+) binds increasingly to bacterial surface carboxyl functional groups, with an average distance between the U atom and the C atom of 2.89+ or -0.02 Aa. This U-C distance indicates an inner-sphere complex with two oxygen atoms shared between the UO (sub 2) (super 2+) and the carboxyl ligand. The results of this XAFS study confirm the uranyl-bacterial surface speciation model.

These libraries behave statistically as though they correspond to populations containing roughly 4.0 plus or minus 1.6% of the random dodecapeptides and 7.9 plus or minus 2.6% of the random constrained heptapeptides that are theoretically possible within the phage populations. Analysis of amino acid residue occurrence patterns shows no demonstrable influence on sequence censorship by Escherichia coli tRNA isoacceptor profiles or either overall codon or Class II codon usage patterns, suggesting no metabolic constraints on recombinant p3 synthesis. There is an overall depression in the occurrence of cysteine, arginine and glycine residues and an overabundance of proline, threonine and histidine residues. The majority of position-dependent amino acid sequence bias is clustered at three positions within the inserted peptides of the dodecapeptide library, +1, +3 and +12 downstream from the signal peptidase cleavage site. Conformational tendency measures of the peptides indicate a significant preference for inserts favoring a beta -turn conformation. The observed protein sequence limitations can primarily be attributed to genetic codon degeneracy and signal peptidase cleavage preferences. These data suggest that for applications in which maximal sequence diversity is essential, such as epitope mapping or novel receptor identification, combinatorial peptide libraries should be constructed using codon-corrected trinucleotide cassettes within vector-host systems designed to minimize morphogenesis-related censorship.

AN - 72107788; 12240724 AB - This paper examines the probability that a localized area with elevated contamination can be found by using a mobile detector. In the case studied, the area of elevated contamination has an elliptical shape and the detector has a circular field of view. The probability of finding the contaminated area is a function of factors related to both the contaminated area and the detector. The paper examines the dependence of the probability on a number of these factors. The results presented are applicable to any characteristic that can be detected with a scanning system that provides complete coverage of an area. They can be used as the basis for designs or evaluations that involve determining whether localized areas of contamination are present in an area of interest.

This paper presents an approach to numerical modeling in which drain cells in a finite-difference model are used as analogs for preferential flowpaths or conduits in karst environments. In this study, conduits in mixed-flow systems are simulated by assigning sequences of adjacent drain cells from the locations of tracer releases, sinkholes, or other karst features to outlet springs along inferred flowpaths. These paths are determined by the locations of losing stream segments, ephemeral stream beds, fracture lineaments, other surficial characteristics, or results of geophysical surveys, combined with the results of dye traces. The elevations of the drains at the discharge ends of the inferred flowpaths are set to the elevations of discharge springs; the elevations at the beginning of the inferred flowpaths are estimated from field data and are adjusted as necessary during model calibration. To simulate a free-flowing conduit, a high conductance is assigned to each drain to promote the removal of water by modeled conduits and to eliminate the need for drain-specific information that would be very difficult to obtain. Calculations were performed for two sites: one near Hohenfels, Germany, and one near St. Louis, Missouri. The potentiometric surfaces produced by these simulations agreed well with field data. The head contours in the vicinity of the karst features behaved in a manner consistent with a flow system having both diffuse and conduit components, and the sum of the volumetric flow out of the drain cells agreed closely with spring discharges and stream flows. Because of the success of this approach, it is recommended for testing of conceptual flow models and for regional studies in which little site-specific information is available, and general flow characteristics are desired.

It is a sole-source aquifer that supplies water to more than 1.5 million people in San Antonio and the Austin-San Antonio corridor. Severe flooding occurred in portions of south-central Texas between October 17 and 19, 1998. At least 30 in. of rainfall was documented in southern Hays County. The USGS indicated that about 2,300 mi2 in 12 counties received at least 12 in. of rain. Response to the October 1998 rainfall included flooding of major rivers and streams, increases in water levels in monitor wells, and increased flows from discharge springs, including such major discharge locations as San Marcos and Comal Springs. Historical flood peaks were recorded by 27 streamflow-gaging stations; one gage on the Guadalupe River measured a peak flow that was 2.6 times the previously recorded high flow. A statistical study of the hydrological data (river flows, spring flows, and water levels in monitor wells) associated with the storm event indicated the following: the response of river and stream flows was very rapid with pronounced peaks in flow and rapid recession curves, typical of a karst environment; responses of flows from discharge springs were rapid, indicating a strong connection with surface water; a more rapid rise to peak flows in San Marcos Springs relative to Comal Springs may correspond with a smaller watershed or a higher transmissivity aquifer; the time needed for flows from discharge springs to return to their pre-event values were long and depended on the size of the watershed and the aquifer transmissivity; periods of nearly constant discharge from springs indicated the presence of substantial storage in the Edwards Aquifer at a depth less than that achieved for peak discharges; cross-correlation between flows in San Marcos and Comal Springs was high for a zero-day lag time, consistent with a conceptual model in which there is strong communication with surface waters; and water levels in wells completed in similar recharge and fresh-water zones showed high cross-correlation.

A series of shaking table tests of the structure were performed for a fixed base design and for a base isolation design. Two different types of LRB were used: natural rubber bearings (NRB) and lead rubber bearings (LLRB). Three different designs for the LLRB were tested; each design had a different diameter of lead plug, and thus, different damping values. Artificial time histories of peak ground acceleration 0.4g were used in both the tests and the analyses. In both shaking table tests and analyses, as expected, the acceleration responses of the seismically isolated test structure were considerably reduced. However, the shear displacement at the isolators was increased. To reduce the shear displacement in the isolators, the diameter of the lead plug in the LLRB had to be enlarged to increase isolator damping by more than 24%. This caused the isolator stiffness to increase, and resulted in amplifying the floor acceleration response spectra of the isolated test structure in the higher frequency ranges with a monotonic reduction of isolator shear displacement.

While hydrogen will likely be the ultimate fuel to power fuel-cell vehicles, because of current infrastructure constraints, hydrogen-carrying fuels are being investigated as transitional fuel-cell fuels. A complete well-to-wheels (WTW) evaluation of fuel-cell vehicle energy and emission effects that examines (1) energy feedstock recovery and transportation; (2) fuel production, transportation, and distribution; and (3) vehicle operation must be conducted to assist decision makers in selecting the fuel-cell fuels that achieve the greatest energy and emission benefits. A fuel-cycle model developed at Argonne National Laboratory - called the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model - was used to evaluate well-to-wheels energy and emission impacts of various fuel-cell fuels. The results show that different fuel-cell fuels can have significantly different energy and greenhouse gas emission effects. Therefore, if fuel-cell vehicles are to achieve the envisioned energy and emission reduction benefits, pathways for producing the fuels that power them must be carefully examined.

This paper focuses on the approach of obtaining a variance from existing, applicable LDR treatment standards. It describes the types of available variances, which include (1) determination of equivalent treatment (DET); (2) treatability variance; and (3) treatment variance for contaminated soil. The process for obtaining each type of variance is also described. Data are presented showing that historically the U.S. Environmental Protection Agency (EPA) processed DET petitions within one year of their date of submission. However, a 1999 EPA policy change added public participation to the DET petition review, which may lengthen processing time in the future. Regarding site-specific treatability variances, data are presented showing an EPA processing time of between 10 and 16 months. Only one generically applicable treatability variance has been granted, which took 30 months to process. No treatment variances for contaminated soil, which were added to the federal LDR program in 1998, are identified as having been granted.

Expression of VHb in heterologous bacteria often enhances growth and increases yields of recombinant proteins and production of antibiotics, especially under oxygen-limiting conditions. There is evidence that VHb interacts with bacterial respiratory membranes and cytochrome bo proteoliposomes. We have examined whether there are binding sites for VHb on the cytochrome, using the yeast two-hybrid system with VHb as the bait and testing every Vitreoscilla cytochrome bo subunit as well as the soluble domains of subunits I and II. A significant interaction was observed only between VHb and intact subunit I. We further examined whether there are binding sites for VHb on cytochrome bo from Escherichia coli and Pseudomonas aeruginosa, two organisms in which stimulatory effects of VHb have been observed. Again, in both cases a significant interaction was observed only between VHb and subunit I. Because subunit I contains the binuclear center where oxygen is reduced to water, these data support the function proposed for VHb of providing oxygen directly to the terminal oxidase; it may also explain its positive effects in Vitreoscilla as well as in heterologous organisms.

The clathrate cages are multiply occupied, with a cluster of two H (sub 2) molecules in the small cage and four in the large cage. Substantial softening and splitting of hydrogen vibrons indicate increased intermolecular interactions. The quenched clathrate is stable up to 145 kelvin at ambient pressure. Retention of hydrogen at such high temperatures could help its condensation in planetary nebulae and may play a key role in the evolution of icy bodies.

AFM images revealed the presence of approximately 0.1 to 1 mu m-wide flat terraces delimited by steps of one to several unit cells in height. These steps follow approximately directions given by the intersection of growth faces. Modeling of X-ray reflectivity data indicates that surface silica groups on flat terraces have only one free Si-O bond each (presumably hydroxylated), except for some having two free Si-O bonds observed on a single (100) surface. Vertical relaxation of atomic positions (<0.4 Aa for terminal oxygens and <0.2 Aa for silicon and oxygen atoms fully coordinated to structural tetrahedra) is limited to a depth of 14 Aa. Electron density profiles for all measured interfaces are consistent with a single layer of adsorbed water, with no evidence for additional organization of water molecules into distinct layers extending into the bulk solution. Similar interfacial structures were observed for natural and annealed surfaces of identical crystallographic orientation, indicating that extensive reconstruction of the silica network at the quartz surface did not occur under the annealing conditions.

We measure productivity while treating pollution as an undesirable output. Our estimates show that technical change has contributed to productivity and environmental performance growth in the container glass industry, an energy and pollution intensive sector. Changes in inter-plant efficiency over time have made this productivity growth more rapid than otherwise would have occurred with the underlying technical change. The efficiency estimates show that there are both opportunities to improve productivity and reduce pollution in this industry, as well as productivity losses associated with the emissions control. The shadow prices for NOx, the undesirable output we analyze, is quite high compared to other regulated sectors.

Five distinct amorphous forms were studied with neutron scattering, and many more forms may be possible. Radial distribution functions indicate that the structure evolves systematically between 4 and 8 angstroms. The phase transformations in low-temperature liquid water may be much more complex than currently understood.

AN - 72034661; 12198962 AB - The Army requires analytical methods that can detect chemical agents down to the low part-per-billion (ppb) levels in their waste streams in order to meet various state regulations regarding the classification of hazardous waste. Analytical methods were developed for the measurement of sarin (GB) and soman (GD) at ppb levels that involved preconcentration of relatively large volumes (40-150 microliters) of a chloroform extract onto a sorbent cartridge, followed by thermal desorption and analysis by GC-flame photometric detection. Certified reporting limits (CRLs) achieved with these methods ranged from 8.3 to 19 ppb for GB and from 1.8 to 5.3 ppb for GD in the three matrices screened. Method detection limits (MDLs) achieved with these methods ranged from 1.7 to 8.2 ppb for GB and from 0.39 to 1.2 ppb for GD.

Water content, soil organic matter (SOM), and metal oxides (MOs) were found to be the factors most influential in the fate and transport of gaseous ozone in unsaturated porous media. The migration velocity of the gaseous ozone front was inversely proportional to the MO content of the porous media. Increased water content at fixed gas flux decreased the ozone breakthrough time proportionally as a result of reduced gas pore volume (PV) in the column, and increased pore water interfered with reactions of gaseous ozone with SOM and MOs on the surface of porous media. The feasibility of in-situ ozone injection for the remediation of unsaturated soils contaminated with either phenanthrene or diesel-range organics (DROs) was investigated under various conditions. The maximum removal after 1 h of ozone injection was achieved in columns packed with baked sand, followed, in descending order, by glass beads and by sand, indicating that catalytic ozone decomposition with MOs in columns packed with baked sand enhanced hydroxyl radical formation and resulted in increased contaminant removal. Overall removal efficiency of multicomponent C (sub 10) -C (sub 24) DROs after 14 h of ozonation was 78.7%. Ozone transport was retarded considerably because of the high ozone demand of DROs, requiring more than 6 h for the gaseous ozone to initially break through the soil column under the experimental conditions tested in this study. Overall, gaseous ozone was readily delivered and transported to remediate unsaturated soils contaminated with phenanthrene and DROs.

At high population densities, these pheromones elicit diverse responses that include bioluminescence, biofilm formation, production of antimicrobials, DNA exchange, pathogenesis and symbiosis. Many of these regulatory systems require a pheromone-dependent transcription factor similar to the LuxR protein of Vibrio fischeri. Here we present the structure of a LuxR-type protein. TraR of Agrobacterium tumefaciens was solved at 1.66 ansgrom as a complex with the pheromone N-3-oxooctanoyl-L-homoserine lactone (OOHL) and its TraR DNA-binding site. The amino-terminal domain of TraR is an alpha / beta / alpha sandwich that binds OOHL, whereas the carboxy-terminal domain contains a helix--turn--helix DNA-binding motif. The TraR dimer displays a two-fold symmetry axis in each domain; however, these two axes of symmetry are at an approximately 90 degree angle, resulting in a pronounced overall asymmetry of the complex. The pheromone lies fully embedded within the protein with virtually no solvent contact, and makes numerous hydrophobic contacts with the protein as well as four hydrogen bonds: three direct and one water-mediated.

AN - 71830084; 12071692 AB - We outline a high throughput process for the production of bacterial expression clones using automated liquid handlers. The protocol consists of a series of interlinked methods representing liquid manipulations or incubations on various stations of the automation system. The methods employ the ligation-independent cloning approach that enables the simultaneous production of plasmids for different expression systems. The current cloning protocol spans 3 days with a linear throughput of 400 targets per production run. This automated approach enables the production of large numbers of bacterial expression clones and ultimately purified proteins. Although they were developed for structural genomics, these molecular protocols can also be applied in high throughput strategies such as those used for site-specific mutagenesis or protein interaction studies.

AN - 71785397; 12046755 AB - An external exposure model has been developed for the RESRAD computer code that provides flexibility in modeling soil contamination configurations for calculating external doses to exposed individuals. This model is based on the dose coefficients given in the U.S. Environmental Protection Agency's Federal Guidance Report No. 12 (FGR-12) and the point kernel method. It extends the applicability of FGR-12 data to include the effects of different source geometries, such as cover thickness, source thickness, source area, and shape of contaminated area of a specific site. A depth factor function was developed to express the dependence of the dose on the source thickness. A cover-and-depth factor function, derived from this depth factor function, takes into account the dependence of dose on the thickness of the source region and the thickness of the cover above the source region. To further extend the model for realistic geometries, area and shape factors were derived that depend not only on the lateral extent of the contamination, but also on source thickness, cover thickness, and radionuclides present. Results obtained with the model generally compare well with those from the Monte Carlo N-Particle transport code.

To estimate initial losses over sub-basins, transmission losses through channel routing, and downstream runoff, we developed an integrated model combining spatial rainfall distribution, an appropriate basin unit hydrograph, and appropriate infiltration parameters. Watersheds and stream networks identified from digital terrain elevation data were verified by comparison with co-registered Landsat thematic mapper scenes and geologic maps. Records of a November 1994 storm event acquired from rain gauges along the Nile River and the Red Sea shore were used to generate a spatial precipitation distribution for the study area. A 2 hour design hyetograph was adopted from rain gauge data for the 1994 flood event. The model was tested against records from the November 1994 flood event at the outlets of the Tarfa and Hammamat watersheds. Groundwater recharge rates were estimated for the alluvial aquifers within the major watersheds of the north Eastern Desert. We estimated that during the 1994 flood event, the ground water recharge through transmission losses ranged from 21 to 31% (Tarfa: 15.8X10 (super 6) m (super 3) ; Asyuti: 20X10 (super 6) m (super 3) , Qena: 49X10 (super 6) m (super 3) , Hammamat: 59X10 (super 6) m (super 3) ) of the precipitated volume. The initial losses ranged from 65 to 77%. Only 3-7% of the precipitation reached the watershed outlets. Archival data show that rainfall events of the size of the November 1994 storm or larger occur every 40 months; thus, the annual recharge rates for the Tarfa, Asyuti, Qena, and Hammamat alluvial aquifers are estimated at 4.7X10 (super 6) m (super 3) , 6X10 (super 6) m (super 3) , 14.7X10 (super 6) m (super 3) , and 17.7X10 (super 6) m (super 3) , respectively. Implications for the use of these renewable ground waters and similar water resources in other arid areas of Egypt and in neighboring countries are clear.

These levels are expressed as dosages measured in milligram-minutes per cubic meter (mg-min/m super(3)). The National Advisory Council has also proposed acute emergency guideline levels (AEGLs) for the agents. The AEGLs are threshold exposure limits for the general public for mild effects, serious adverse effects, and lethality. They are expressed as air concentrations (in units of mg/m super(3)) and are applicable to emergency exposure periods ranging from 10 min to 8 h. The report discusses strengths and deficiencies in the levels, important parameters (i.e., exposure time, breathing rate) that need to be explicitly addressed in deriving the guideline levels, and possible impacts that could result from using AEGLs instead of guideline dosages in future assessments.

However, as described by Simpson's paradox, this is not necessarily a reasonable expectation. The impact of Simpson's paradox on an ecological question was tested using a meta-analysis of data on plant responses to arbuscular mycorrhizas. Although species-level response commonly declines as phosphorus availability increases, we hypothesized that the community-level response could either decline or remain constant. As expected, mycorrhizal response of individual species declined significantly as P supply increased. The response averaged across multiple species was negative but not robust, so we cannot distinguish clearly between the hypotheses. It is impossible to assume that community-level responses to environmental gradients are the same as those found at species level. We recommend that experimental tests of hypotheses should allow species identity to change with the environment.

The Thermotoga maritima TM0065 gene codes for a protein (TM-IclR) that is homologous to the IclR family. We have determined the crystal structure of TM-IclR at 2.2 Aa resolution using MAD phasing and synchrotron radiation. The protein is composed of two domains: the N-terminal DNA-binding domain contains the winged helix-turn-helix motif, and the C-terminal presumed regulatory domain is involved in binding signal molecule. In a proposed signal-binding site, a bound Zn super(2+) ion was found. In the crystal, TM-IclR forms a dimer through interactions between DNA-binding domains. In the dimer, the DNA-binding domains are 2-fold related, but the dimer is asymmetric with respect to the orientation of signal-binding domains. Crystal packing analysis showed that TM-IclR dimers form a tetramer through interactions exclusively by signal-binding domains. A model is proposed for binding of IclR-like factors to DNA, and it suggests that signal-dependent transcription regulation is accomplished by affecting an oligomerization state of IclR and therefore its affinity for DNA target.

AN - 71661853; 11993994 AB - We report on the unexpected structural changes caused by substitution of acidic amino acids in the Q(B) binding pocket of the bacterial photosynthetic reaction center by alanines. The mutations targeted key residues L212Glu and L213Asp of this transmembrane protein-cofactor complex. The amino acid substitutions in the L212Ala-L213Ala mutant reaction center ("AA") were known to affect the delivery of protons after the light-induced generation of Q(B)(-), which renders the AA strain incapable of photosynthetic growth. The AA structure not only revealed side chain rearrangements but also showed movement of the main chain segments that are contiguous with the mutation sites. The alanine substitutions caused an expansion of the cavity rather than its collapse. In addition, Q(B) is found mainly in the binding site that is proximal to the iron-ligand complex (closest to Q(A)) as opposed to its distal binding site (furthest from Q(A)) in the structure of the wild-type reaction center. The observed rearrangements in the structure of the AA reaction center establish a new balance between charged residues of an interactive network near Q(B). This structurally and electrostatically altered complex forms the basis for future understanding of the structural basis for proton transfer in active reaction centers which retain the alanine substitutions but carry a distant compensatory mutation.

Egypt constructed (1964-1971) the Aswan High Dam, creating the Lake Nasser reservoir (length: 500 km; average width: 12 km) and is constructing the Tushka Canal to channel 5.0X10 (super 9) m (super 3) /yr of Lake Nasser water to reclaim 0.5X10 (super 6) acres of desert lands. The model, constrained by regional-scale groundwater flow and near-lake head data, was successfully calibrated to temporal-observation heads from 1970 to 2000 that reflect variations in lake levels. Predictive analyses for the subsequent 50-yr period were conducted by employing the calibrated model. Simulations of long-term effects, beyond year 2000, of Lake Nasser on recharge and temporal groundwater head (base case scenario) show that recharge from the lake will continue at a much slower rate than during the 30-yr period of 1970-2000 (with approximately 86% reduction in 30-yr recharge). The modest projected pumping and injection activities in the study area are not expected to cause major deviation in the overall head distribution compared to the base case scenario. The investigation of effects of the new irrigation land development on the Nubian aquifer indicated that many of the proposed irrigation areas, especially those with small aquifer thickness, will become fully saturated with introduced water, resulting in potential flooding and salinization.

AN - 72895374; 12805978 AB - Section 316(b) of the Clean Water Act (CWA) requires that "the location, design, construction, and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact." As the U.S. Environmental Protection Agency (EPA) develops new regulations to implement Section 316(b), much of the debate has centered on adverse impingement and entrainment impacts of cooling-water intake structures. Depending on the specific location and intake layout, once-through cooling systems withdrawing many millions of gallons of water per day can, to a varying degree, harm fish and other aquatic organisms in the water bodies from which the cooling water is withdrawn. Therefore, opponents of once-through cooling systems have encouraged the EPA to require wet or dry cooling tower systems as the best technology available (BTA), without considering site-specific conditions. However, within the context of the broader scope of the CWA mandate, this focus seems too narrow. Therefore, this article examines the phrase "minimizing adverse environmental impact" in a holistic light. Emphasis is placed on the analysis of the terms "environmental" and "minimizing." Congress chose "environmental" in lieu of other more narrowly focused terms like "impingement and entrainment," "water quality," or "aquatic life." In this light, BTA for cooling-water intake structures must minimize the entire suite of environmental impacts, as opposed to just those associated with impingement and entrainment. Wet and dry cooling tower systems work well to minimize entrainment and impingement, but they introduce other equally important impacts because they impose an energy penalty on the power output of the generating unit. The energy penalty results from a reduction in plant operating efficiency and an increase in internal power consumption. As a consequence of the energy penalty, power companies must generate additional electricity to achieve the same net output. This added production leads to additional environmental impacts associated with extraction and processing of the fuel, air emissions from burning the fuel, and additional evaporation of freshwater supplies during the cooling process. Wet towers also require the use of toxic biocides that are subsequently discharged or disposed. The other term under consideration, "minimizing," does not equal "eliminating." Technologies may be available to minimize but not totally eliminate adverse environmental impacts.

In addition, federal courts are beginning to apply the Americans with Disabilities Act to emergency planning. This study characterizes special-needs households that are located in the vicinity of a chemical weapons storage site in AL. For this study, a special-needs household is defined as a residence having at least one person with physical or mental problems, a transportation dependence, or a child who is home alone at times & requires assistance from outside the family or current circle of relatives, friends, & neighbors to take specific protective actions. Attitudes toward specific protective actions & an assessment of the ability of the special-needs household to take those actions were also sought out. Approximately 9% of the community's households were identified as containing persons with special needs who require assistance during emergencies. The study also identified the highly perishable nature of special-needs population records maintained by emergency management agencies. During a data-verification process conducted 3 months after the data collection effort concluded, almost half of the previously identified 3,294 individuals with special needs had their situation change or could not be reached for verification. Concurrently, 1,090 new persons with special needs identified themselves as needing assistance. Recommendations are made to the emergency planning community for addressing the support needs of special populations. 3 Tables, 28 References. Adapted from the source document.

On the basis of assumptions for the mass transfer and reactions of ozone, three approaches were considered: equilibrium, kinetic, and lump models. Water-saturation-dependent reactions of gaseous ozone with soil organic matter (SOM) and phenanthrene were employed. The models were solved numerically by using the finite-difference method, and the model parameters were determined by using the experimental data of Hsu [The use of gaseous ozone to remediate the organic contaminants in the unsaturated soils, PhD Thesis, Michigan State Univ. East Lansing, MI, 1995]. The transport of gas-phase ozone is significantly retarded by ozone consumption due to reactions with SOM and phenanthrene, in addition to dissolution. An operation time of 156 h was required to completely remove phenanthrene in a 5-m natural soil column. In actual situations, however, the operation time is likely to be longer than the ideal time because of unknown factors including heterogeneity of the porous medium and the distribution of SOM and contaminant. The ozone transport front length was found to be very limited (<1 m). The sensitivity analysis indicated that SOM is the single most important factor affecting in situ ozonation for the remediation of unsaturated soil contaminated with phenanthrene. Models were found to be insensitive to the reaction mechanisms of phenathrene with either gas-phase ozone or dissolved ozone. More study is required to quantify the effect of OH super([character]) formation on the removal of contaminant and on ozone transport in the subsurface.

Although the probabilistic analysis for each site will be unique because of the probabilistic inputs selected, their site-specific distributions, and any interrelationship between the inputs, the insights gained during the participation of the RESRAD-OFFSITE computer code in the Biosphere Modelling and Assessment and Biospheric Model Validation probabilistic studies will be useful guides in performing other probabilistic dose and risk analyses. Correlation and regression analysis can be performed on raw or ranked data, and the appropriate analysis can be chosen on the basis of the coefficient of determination. Partial (rank) correlation coefficients and standardized (rank) regression coefficients can be used to identify probabilistic inputs that have a linear (or monotonic) effect on probabilistic outputs and to quantify these effects. A suite of scatter plots can be used to confirm this identification and to also identify the inputs that have nonlinear, nonmonotonic effects on probabilistic outputs.

The primary radionuclide of concern in NORM wastes are radium-226 (Ra-226) of the uranium-238 decay series; radium-228 of the thorium-232 decay series is also present, but usually at lower concentrations. The production waste streams most likely to be contaminated by elevated radium concentrations include produced water, scale, and sludge. Scales and sludges removed from production equipment sometimes are disposed of by landspreading, a method in which wastes are spread over the soil surface to allow the hydrocarbon component of the wastes to degrade. The disposal of NORM-contaminated wastes by landspreading was modeled to evaluate potential radiological doses to the general public. A variety of future land use scenarios-including residential, industrial, recreational, and agricultural scenarios-were considered. The waste streams considered included scales and sludges containing NORM above background levels. The RESRAD computer code was used to estimate the radiological doses for the maximally exposed receptor for each scenario. Depending on the land-use scenario, potential exposure pathways evaluated for the general public included external radiation; inhalation of contaminated particulates; inhalation of indoor and outdoor radon-222; inadvertent ingestion of contaminated soil; and ingestion of crops, milk, and meat grown on the property. Potential doses were modeled for a unit concentration of 1 Bq g super(-1) of Ra-226 in soil. Because dose increases linearly with radium concentration, doses were extrapolated for a range of radium concentrations.

Although crystalline Np(IV) dioxide NpO2 is believed to be the thermodynamically stable Np solid in groundwaters similar to those found in and around Yucca Mountain, NpO2 may be kinetically inhibited from precipitating from homogeneous Np(V)-containing solutions below approximately 200 C. In addition, low concentrations of dissolved Np in oxidizing, uranium-saturated waters may favor the co-precipitation of Np in U(VI) (uranyl) solids, as reported recently in corrosion experiments on spent nuclear fuel. Here we report recent corrosion experiments with Np-doped U oxides, in which the starting solids were exposed to water-saturated air for several weeks in sealed stainless-steel vessels. Our results indicate that uranyl oxyhydroxides incorporate small amounts of Np, and that crystalline NpO2 will precipitate at 150 C and 90 C. The coexistence of Np-bearing uranyl compounds with pure Np oxides helps to define the limit of Np solubility in the structures of uranyl compounds under the experimental conditions. Applying our results to a recently developed model for predicting dissolved Np concentrations in U-saturated groundwaters shows reasonable agreement with experimentally measured Np concentration from studies on the aqueous corrosion of spent nuclear fuels.

AN - 71437927; 11847333 AB - Synchrotron x-radiography and a fast x-ray detector were used to record the time evolution of the transient fuel sprays from a high-pressure injector. A succession of 5.1-microsecond radiographs captured the propagation of the spray-induced shock waves in a gaseous medium and revealed the complex nature of the spray hydrodynamics. The monochromatic x-radiographs also allow quantitative analysis of the shock waves that has been difficult if not impossible with optical imaging. Under injection conditions similar to those found in operating engines, the fuel jets can exceed supersonic speeds and result in gaseous shock waves. JF - Science (New York, N.Y.)

AN - 71504429; 11873511 AB - Mice homozygous for the autosomal recessive "wasted" mutation (wst/wst) have abnormalities in T lymphocytes and in the anterior motor neuron cells of the spinal cord, leading to sensitivity to low doses of ionizing radiation, hind limb paralysis, and immunodeficiency. This defect results in a failure to gain weight by 20 days of age and death by 28 days. The wasted mutation (previously mapped to mouse chromosome 2) is shown to be a 3-bp deletion in a T cell-specific (and perhaps motor-neuron-specific) regulatory region (promoter) of the proliferating cell nuclear antigen (PCNA) gene on mouse chromosome 2. A regulatory element is also shown to be important in PCNA expression in T lymphocytes and motor neuron cells affected by the 3-bp deletions in the PCNA promoter. The model is as follows. Absence of PCNA expression in the thymuses (and motor neurons) of wasted mice causes cellular apoptosis. This absence of expression is mediated by a positive transfactor that can bind to the wild-type but not to the wasted mutant PCNA promoter. The bound protein induces late expression of PCNA in T lymphocytes and prevents onset of radiation sensitivity in the cells.

AN - 71413017; 11797897 AB - Workplace air sampling was performed during the decommissioning of a previously active plutonium glovebox facility located at Argonne National Laboratory. Personal air samplers (PAS) were used to measure breathing zone activity concentrations of workers engaged in size-reducing contaminated gloveboxes. Stationary air samplers (SAS) were used to measure the work area activity concentrations and test their application in providing representative sampling of breathing zone activity concentrations. The relative response of these samplers (PAS:SAS) was tracked during the course of the decommissioning work, with results yielding favorable agreement to within a factor of +/-5. A cascade impactor was used to determine the particle size distribution of workplace aerosols. The average activity median aerodynamic diameter (AMAD) was estimated to be 3.0 microm, with a corresponding geometric standard deviation of 2.4. A gas-flow proportional counter was utilized to measure the gross alpha activity collected on both the SAS glass fiber and the PAS cellulose fiber filters. A subset of this filter group was subsequently analyzed using an alpha spectrometer post radiochemical processing and isotopic separation. The quantity of alpha activity measured on the SAS filters was generally within +/-30% of the alpha spectrometry measurements. However, measurements made of the activity present on the PAS cellulose fiber filters were consistently underestimated using a gas-flow proportional counter, suggesting a small correction factor of 15-20% to account for the absorption of alpha particle emissions.

AN - 72811406; 12515341 AB - As more is learned about the complex nature and extent of environmental impacts from progressive human disturbance, scientists, policy analysts, decision makers, educators, and communicators are increasingly joining forces to develop strategies for preserving and protecting the environment. The Eco-Informa Foundation is an educational scientific organization dedicated to promoting the collaborative development and sharing of scientific information. The Foundation participated in a recent international conference on environmental informatics through a special symposium on integrating information for better environmental decisions. Presentations focused on four general themes: (1) remote sensing and data interpretation, including through new knowledge management tools; (2) risk assessment and communication, including for radioactively contaminated facilities, introduced biological hazards, and food safety; (3) community involvement in cleanup projects; and (4) environmental education. The general context for related issues, methods and applications, and results and recommendations from those discussions are highlighted here.

AN - 71351437; 11751325 AB - We have examined the influence of surface hydrogen bonds on the stability of proteins by studying the effects of mutations of human immunoglobulin light chain variable domain (V(L)). In addition to the variants Y27dD, N28F, and T94H of protein kappa IV Len that were previously described, we characterized mutants M4L, L27cN, L27cQ, and K39T, double mutant M4L/Y27dD, and triple mutant M4L/Y27dD/T94H. The triple mutant had an enhanced thermodynamic stability of 4.2 kcal/mol. We determined the structure of the triple mutant by x-ray diffraction and correlated the changes in stability due to the mutations with changes in the three-dimensional structure. Y27dD mutant had increased stability of Len by 2.7 kcal/mol, a large value for a single mutation. Asp27d present in CDR1 formed hydrogen bonds with the side-chain and main-chain atoms within the loop. In the case of the K39T mutant, which reduces stability by 2 kcal/mol, Lys39 in addition to forming a hydrogen bond with a carbonyl oxygen of a neighboring loop may also favorably influence the surface electrostatics of the molecule. We showed that hydrogen bonds between residues in surface loops can add to the overall stability of the V(L) domains. The contribution to stability is further increased if the surface residue makes more than one hydrogen bond or if it forms a hydrogen bond between neighboring turns or loops separated from each other in the amino acid sequence. Based on our experiments we suggest that stabilization of proteins might be systematically accomplished by introducing additional hydrogen bonds on the surface. These substitutions are more straightforward to predict than core-packing interactions and can be selected to avoid affecting the protein's function.

RESRAD is a multimedia pathway analysis code designed to evaluate radiological exposures resulting from radiological contamination in soil. The dose distribution was obtained by using a set of default parameter distribution/values. Most of the variations in the output dose distribution could be attributed to uncertainty in a small set of input parameters that could be considered as sensitive parameter distributions. The identification of the sensitive parameters is a first step in the prioritization of future research and information gathering. When site-specific parameter distribution/values are available for an actual site, the same process should be used with these site-specific data. Regression analysis used to identify sensitive parameters indicated that the dominant pathways depended on the radionuclide and source configurations. However, two parameter distributions were sensitive for many radionuclides: the external shielding factor when external exposure was the dominant pathway and the plant transfer factor when plant ingestion was the dominant pathway. No single correlation or regression coefficient can be used alone to identify sensitive parameters in all the cases. The coefficients are useful guides, but they have to be used in conjunction with other aids, such as scatter plots, and should undergo further analysis.

The RESRAD code applies to the cleanup of sites (soils) and the RESRAD-BUILD code applies to the cleanup of buildings and structures. This work describes the procedure used to enhance the deterministic RESRAD and RESRAD-BUILD codes for probabilistic dose analysis. A six-step procedure was used in developing default parameter distributions and the probabilistic analysis modules. These six steps include (1) listing and categorizing parameters; (2) ranking parameters; (3) developing parameter distributions; (4) testing parameter distribution for probabilistic analysis; (5) developing probabilistic software modules; and (6) testing probabilistic modules and integrated codes. The procedures used can be applied to the development of other multimedia probabilistic codes. The probabilistic versions of RESRAD and RESRAD-BUILD codes provide tools for studying the uncertainty in dose assessment caused by uncertain input parameters. The parameter distribution data collected in this work can also be applied to other multimedia assessment tasks and multimedia computer codes.

After transuranic wastes were identified as a separate category of radioactive wastes (distinct from low-level wastes) in 1970 by the U.S. Atomic Energy Commission, they were generally segregated and placed in retrievable storage pending the availability of a geologic repository. Updated information on buried transuranic wastes was recently developed to support future decisions on how to manage these materials. This paper summarizes the approach used to develop this information for U.S. Department of Energy facilities and presents the volumes and transuranic activities of these wastes. The total volume of buried transuranic wastes at DOE sites is approximately 126,000 m super(3) with a much smaller volume (about 11,000 m super(3)) disposed of at intermediate depths. The reported transuranic activity in these previously disposed of wastes is about 28,000 TBq.

These time series estimates show considerable variability, some of which results from failure of the chlorophyll retrieval algorithm, especially during carbonate precipitation events (whitings) that occur in the early fall, and some of which reflects annual and inter-annual variations in phytoplankton abundance. Comparing years, the average chlorophyll concentration was higher in 1999 than in either 1998 or 2000. Both 1998 and 1999 showed patterns consistent with a spring bloom followed by a late summer minimum, but this pattern was much harder to discern in 2000. Because the estimated chlorophyll concentrations were lower in 1998 than in 1999, integrated primary production, estimated by using a multivariate model driven with the satellite observations along with in situ temperature measurements, also appeared to be lower in 1998 than in 1999. This is in contrast with independent estimates, based both on the isotopic composition of organic carbon and the flux of biogenic silica collected in sequencing sediment traps located 30 m below the surface in the middle of the southern basin, that show higher production in 1998 than in either 1999 or 2000.

Spermidine synthase (putrescine aminopropyltransferase, PAPT) catalyzes the biosynthesis of spermidine, a ubiquitous polyamine. The crystal structure of the PAPT from Thermotoga maritima (TmPAPT) has been solved to 1.5 Angstrom resolution in the presence and absence of AdoDATO (S-adenosyl-1,8-diamino-3-thiooctane), a compound containing both substrate and product moieties. This, the first structure of an aminopropyltransferase, reveals deep cavities for binding substrate and cofactor, and a loop that envelops the active site. The AdoDATO binding site is lined with residues conserved in PAPT enzymes from bacteria to humans, suggesting a universal catalytic mechanism. Other conserved residues act sterically to provide a structural basis for polyamine specificity. The enzyme is tetrameric; each monomer consists of a C-terminal domain with a Rossmann-like fold and an N-terminal beta -stranded domain. The tetramer is assembled using a novel barrel-type oligomerization motif.

When the spin-polarized EPR spectra are recorded at the high field, the singlet-triplet mixing in the radical pairs becomes faster due to the increase of Zeeman interaction, and a sequential electron transfer polarization model, which includes both the primary and secondary radical pairs, should be considered. Application of the sequential electron transfer polarization model for the interpretation of the bacterial RC proteins with a 'slow' electron transfer rate reveals the importance of the protein dynamics. It was shown that the reorganization energy for the electron transfer process between P865HQA and P865HQA, but not the change in the structure of the donor-acceptor complex, is a dominant factor that alters the electron transfer rate. The relaxation data, obtained in the delay after laser flash experiment, have been used to estimate the magnetic interaction in the weakly coupled radical pair. High-frequency spin-polarized EPR spectra allow the quantitative characterization of isotopically labeled quinone exchange in the PS I reaction center proteins.

AN - 72355029; 11746831 AB - The human myeloid HL-60 cell line and its cell variant HL-525 were used to study signaling events leading to apoptosis induction by phorbol 12-myristate 13-acetate (PMA), an activator of protein kinase C (PKC) enzymes. Unlike parental cells, HL-525 cells are PKC-beta deficient and resistant to PMA-induced apoptosis. These cells regain susceptibility to apoptosis induction after transfection with a PKC-beta expression vector. By using this vector and specific neutralizing monoclonal antibodies (mAbs), it was established that PMA-induced apoptosis also called for an interaction between cell-surface alpha(5)beta(1)-integrin and its deposited ligand fibronectin (FN), which is downstream of PKC-beta activation. Experiments with mAbs, the PKC-beta vector, and exogenous FN revealed that the next step entailed an interaction between secreted tumor necrosis factor-alpha and its type I receptor. By using a sphingomyelinase inhibitor, it was concluded that the subsequent step involved ceramide production. Moreover, a permeable ceramide was effective in inducing apoptosis in both HL-60 and HL-525 cells, and this induction was caspase-1 and/or -4 dependent because an inhibitor of these caspases abrogated the induced apoptosis. Based on these and related differentiation studies, we conclude that the above signaling events, the early ones in particular, are shared with PMA-induced macrophage differentiation in the HL-60 cells. It is likely that once these cells acquire their macrophage phenotype and perform their tasks, they become superfluous and are eliminated from the body by a self-triggered apoptotic process that involves our proposed signaling scheme.

However, we find that China's CO sub(2) emissions declined by 7.3% between 1996 (the peak year) and 2000, and CH sub(4) emissions declined by 2.2% between 1997 (the peak year) and 2000. This happened partly because China undertook a radical reform of its coal and energy industries. In addition, China's economy suffered during the Asian economic crisis of 1997 to 1998 to an extent not yet fully understood, and many factories curtailed production or shut down because of economic restructuring policies, resulting in a decline in coal production and consumption. Although China is not a party to the Kyoto Protocol, these recent developments have important implications for the formulation of climate change policies.

ER - TY - JOUR T1 - Structure of Thermotoga maritima stationary phase survival protein SurE: a novel acid phosphatase. AN - 72281562; 11709173 AB - BACKGROUNDThe rpoS, nlpD, pcm, and surE genes are among many whose expression is induced during the stationary phase of bacterial growth. rpoS codes for the stationary-phase RNA polymerase sigma subunit, and nlpD codes for a lipoprotein. The pcm gene product repairs damaged proteins by converting the atypical isoaspartyl residues back to L-aspartyls. The physiological and biochemical functions of surE are unknown, but its importance in stress is supported by the duplication of the surE gene in E. coli subjected to high-temperature growth. The pcm and surE genes are highly conserved in bacteria, archaea, and plants.RESULTSThe structure of SurE from Thermotoga maritima was determined at 2.0 A. The SurE monomer is composed of two domains; a conserved N-terminal domain, a Rossman fold, and a C-terminal oligomerization domain, a new fold. Monomers form a dimer that assembles into a tetramer. Biochemical analysis suggests that SurE is an acid phosphatase, with an optimum pH of 5.5-6.2. The active site was identified in the N-terminal domain through analysis of conserved residues. Structure-based site-directed point mutations abolished phosphatase activity. T. maritima SurE intra- and intersubunit salt bridges were identified that may explain the SurE thermostability.CONCLUSIONSThe structure of SurE provided information about the protein's fold, oligomeric state, and active site.

Yet, how do those charged with deploying emergency services ensure that their efforts will be adequate? Because it is difficult to coordinate detailed planning between responding agencies & the community itself, this paper suggests that the US Army's decision making process, & its synchronization matrix, be adapted & utilized for disaster planning on the civilian level. This particular plan relies heavily on integration, coordination, & synchronization. If these strategies are incorporated, response planning will move away from the current trend of self-reliance & self-sufficiency & will become more effective & efficient. 2 Tables, 4 Figures, 22 References.

The geology consists of coastal plain sediments, of which the presence or absence of clay layers is probably the greatest control for the vertical migration of DNAPL. Geophysical methods consisted of two-dimensional electrical resistivity imaging (2D-ERI), borehole electrical and natural-gamma logging, and direct-push electric logging. Results from modeling the 2D-ERI data provide gross spatial distributions and trends of electrical properties of the subsurface, which can be directly correlated with the underlying geology. The 2D-ERI data have mapped an electrically resistive layer ranging from 7 to 15 m in thickness interpreted to be sands and silts of Pliocene to Holocene in age, which represent a potential contaminant storage and/or migration zone. The base of this zone coincides with an upper clay unit where the resistive layer is thinner (<9 m), and with a lower clay unit where it is thickest. Borehole logging was used to provide vertical control on the position and extent of clay horizons. A thin clay horizon was consistently detected at an average depth of 8m, and most likely acts as the primary barrier against vertical migration of the contamination as contaminant levels are consistently the greatest immediately above. Comparison between the borehole and surface geophysical data indicate that the 2D-ERI models do not fully resolve all of the clay horizons, and that greater vertical resolution is afforded by borehole logging. Combined use of borehole and surface data allows for a more consistent interpretation of the 2D-ERI models, and by extension, provides better information for placing monitor/sampling wells. A topographic depression on the clay surface was mapped using both the resistivity and borehole data.

This paper describes these two new initiatives, discusses some concerns with their outcome, and provides some insight into their potential applicability to the United States market. In particular, the paper compares the regulatory conditions governing fuel economy (test regimes, emissions standards) and the differences in the cost-effectiveness of new fuel economy technology (given differences in fuel prices, vehicle taxation, and other factors affecting technology cost/fuel savings tradeoffs) for the three markets. European and Japanese market conditions are more conducive to improving fuel economy because of less stringent emissions standards (that make direct injection engines more feasible and will likely allow better performance from them) and much higher fuel prices than in the US. However, factors such as high vehicle taxes and, in some European countries, a high percentage of company cars may narrow the gap between the US market and the European market. And very high rates of driving in the US also enhance the cost-effectiveness of efficiency technologies.

Analysis of the crystal structures of complexes between proteins and small molecule ligands revealed that virtually all ligands of molecular weight 300 Da or greater have a continuous binding epitope of 5 residues or more. This observation led to the development of a technique for binding site identification which involves statistical analysis of an affinity-selected set of peptides obtained by screening of libraries of random, phage-displayed peptides against small molecules attached to solid surfaces. A random sample of the selected peptides is sequenced and used as input for a similarity scanning program which calculates cumulative similarity scores along the length of the putative receptor. Regions of the protein sequence exhibiting the highest similarity with the selected peptides proved to have a high probability of being involved in ligand binding. This technique has been employed successfully to map the contact residues in multiple known targets of the anticancer drugs paclitaxel (Taxol), docetaxel (Taxotere) and 2-methoxyestradiol and the glycosaminoglycan hyaluronan, and to identify a novel paclitaxel receptor [1]. These data corroborate the observation that the binding properties of peptides displayed on the surface of phage particles can mimic the binding properties of peptides in naturally occurring proteins. It follows directly that structural context is relatively unimportant for determining the binding properties of these disordered peptides. This technique represents a novel, rapid, high resolution method for identifying potential ligand binding sites in the absence of three-dimensional information and has the potential to greatly enhance the speed of development of novel small molecule pharmaceuticals.

Peptide- and cDNA display methods have the potential to contribute to understanding the mechanisms of certain classes of drugs and to help map protein-protein interactions of physiological importance. Although the critical contribution of comprehensive amino acid sequence databases has been recognized, of equal importance might be structural genomics concepts in the application of display system technology to proteomics research. Lessons learned from the study of antibody-antigen interactions are reviewed here and applied to the field of display technology with the goal of delineating major factors involved in the successful mimicry of natural protein-ligand interactions.

Distinct processes were observed, involving mainly terrace roughening at pH = 1.1 and step motion at pH = 12.9. A gel-like surface coating was observed to form at acidic pH under slow fluid flow-rate conditions. No coating was observed either at alkaline pH or at acidic pH under high fluid flow-rate conditions. The corresponding dissolution rates were measured directly at pH = 1.1 and 12.9 at approximately 50 degrees C using real-time X-ray reflectivity measurements, and reacted interface structures were derived from crystal truncation rod measurements after reaction at both acidic and alkaline pH. Our observations reveal, under these experimental conditions, that 1) orthoclase dissolution is controlled by at least two separate surface reactions having distinct reactive sites; 2) dissolution is stoichiometric at alkaline pH and only minimally nonstoichiometric (limited to one unit-cell depth) at acidic pH; previously identified nonstoichiometric layer thicknesses derived from macroscopic measurements are associated with the formation of the gel-like coatings; 3) dissolution rates measured at freshly cleaved (001) surfaces are comparable to those derived from steady-state powder dissolution rates for both alkaline and acidic pH; and 4) elevated transient dissolution rates are not observed for freshly cleaved surfaces but are obtained under alkaline conditions after reacting the orthoclase (001) surface at acidic pH. These observations clarify differences in orthoclase dissolution mechanisms as a function of pH, demonstrate the utility of AFM and X-ray scattering methods for measuring Aa-scale structures and face-specific dissolution rates on single crystals and place new constraints on the understanding of alkali feldspar weathering processes.

Site NAPL concentrations are typically evaluated using the U.S. Environmental Protection Agency's tiered risk-based corrective action (RBCA) system. Tier 1 uses conservative assumptions and little site-specific data, while tier 2 requires more detailed site-specific data. This paper presents an engineering approach that can be used to predict maximum groundwater NAPL concentrations resulting from NAPL spills. This screening tool was developed by deriving an analytical solution for a partial differential equation describing NAPL transport through the unsaturated zone. Model processes include dissolution, advection, dispersion, sorption, volatilization, and first-order degradation. Results are obtained using two nondimensional parameters and engineering plots for a wide range of conditions. A brief study is provided to demonstrate the application of the model. Because the engineering plots are easy to use and facilitate sensitivity analyses, the model is recommended for screening and RBCA tier 2 analyses.

The SPME field kit sampler is ideal for collecting air and water samples in the field and transporting samples safely to the laboratory. The sampler also allows the sample to be introduced into the GC-MS system without further sample preparation. Results of the tests with Sarin using the SPME technique indicate that a sample collection time of 5 min is sufficient to detect 100 ng/L of Sarin in air. For water samples, Sarin is detected at a concentration of 12 mu g/mL or higher. This method is ideal for screening samples for quick response situations.

Accurate H atom positions were determined at 295 K, 100 K, and 20 (10) K. Only one H position of approximately 50% occupancy was observed for each structure, which confirms a disordered H model. Time-of-flight single-crystal neutron data were also collected at 295 K and 20 K for the Val Malenco clinohumite as an additional check on space group symmetry. The crystal structure of the Kukh-i-Lal clinohumite was further investigated by X-ray single-crystal refinement at 295 K and by piezoelectric measurements. A few, very weak, symmetry-forbidden reflections were observed for each crystal at both ambient and lower temperatures. The same reflections were observed by all methods used. No temperature dependence is indicated, as no additional peaks appear at low temperature, and the intensity of the reflections are sample dependent. It appears that the real structure is made up of P2 (sub 1) and Pb domains so that violations are due to ordering of both H and Ti. No distinct piezoelectric effect was observed that would indicate the absence of a center of symmetry. This points to the simultaneous presence of various enantiomorphic domains, which cancels the piezo-electric effect of individual domains. The decrease in unit-cell volume with F substitution in clinohumites can be explained by the higher concentration of H-site vacancies and the coupled cationic and anionic substitution on the M3 and O/F site.

Implications of Transitioning to a New Transportation Energy Future AN - 20241138; 7501706 AB - U.S. motorists were reminded twice recently (in the spring of 2000 and again in the spring of 2001) that gasoline and diesel fuel prices can escalate rapidly. The escalation of motor fuel prices served as a reminder for some of the energy crises of the 1970s. While there were no price controls and long lines at service stations this time, there was uncertainty about how high fuel prices would go. Beginning in 2000, the Office of Transportation Technologies in the U.S. Department of Energy (DOE)began an examination of the long-term availability of petroleum supplies for U.S. motor vehicles as well as the projected demand. Included in this analysis was a forecast for the future energy demand of automobiles and trucks, as well as several strategies for the use of alternative fuels and the introduction of new propulsion system technologies into the vehicles. The analysis was extended for fifty years to determine the effects on oil and energy demand as well as greenhouse gas emissions as these fuels and vehicle technologies permeated the fleet of vehicles over time. The study participants included staff from several national laboratories, contractors, and the department. This paper summarizes the major findings of the first phase of the study. Forecasts of world petroleum supply and demand are reviewed. The implications (with attention devoted to energy issues and greenhouse gas emissions) of U.S. transportation energy demand under various technology strategies are then examined.

We have estimated the emissions of BC in China, where roughly one-fourth of global anthropogenic emissions is believed to originate. China's high rates of usage of coal and biofuels are primarily responsible for high BC emissions. This paper pays particular attention to the application of appropriate emission factors for China and the attenuation of these emissions where control devices are used. Nevertheless, because of the high degree of uncertainty associated with BC emission factors, we provide ranges of uncertainty for our emission estimates, which are approximately a factor of eight. In our central case, we calculate that BC emissions in China in 1995 were 1342 Gg, about 83% being generated by the residential combustion of coal and biofuels. We estimate that BC emissions could fall to 1224 Gg by 2020. This 9% decrease in BC emissions can be contrasted with the expected increase of 50% in energy use; the reduction will be obtained because of a transition to more advanced technology, including greater use of coal briquettes in place of raw coal in cities and towns. The increased use of diesel vehicles in the future will result in a greater share of the transport sector in total BC emissions. Spatially, BC emissions are predominantly distributed in an east-west swath across China's heartland, where the rural use of coal and biofuels for cooking and heating is widespread. This is in contrast to the emissions of most other anthropogenically derived air pollutants, which are closely tied to population and industrial centers.

ER - TY - JOUR T1 - Heterogeneous NO sub(x) chemistry in the polluted PBL AN - 18180437; 5206176 AB - The significance of heterogeneous mechanisms in controlling gas-phase NO sub(x) (NO, NO sub(2)) mixing ratios in polluted urban air, especially during nighttime, is not well established. Several recent studies have suggested that carbon soot can provide an effective surface for mediating the inter conversion among several NO sub(y) members. However, a number of such reactions reported in the literature have widely varying reaction probabilities and often conflicting pathways. We evaluated several of these reactions and choose the NO sub(2) conversion to HONO on the surface of soot particles for further analysis with a box photochemical model. These calculations show that the conversion of NO sub(2) to HONO on particle surfaces produces a large, measurable signal (up to several parts per billion) in nighttime HONO mixing ratios. Inclusion of this reaction was also shown to have significant impacts on ozone, OH and HO sub(2) in the polluted planetary boundary layer (PBL). The sensitivity of these results to the different reaction rate probabilities ( gamma ) and particle surface areas was also examined.

Our databases and mechanistic understanding of the degradation of such highly irradiated components, however, are not well established. A key question is the nature of irradiation-assisted intergranular cracking at very high doses, i.e. is it purely mechanical failure or is it stress-corrosion cracking? In this work, hot-cell tests and microstructural characterization were performed on Type 304 SS from the hexagonal fuel can of the decommissioned EBR-II reactor after irradiation to approximately 50 dpa at approximately 370 degree C. Slow-strain-rate tensile tests were conducted at 289 degree C in air and in water at several levels of electrochemical potential (ECP), and microstructural characteristics were analyzed by scanning and transmission electron microscopies. The material deformed significantly by twinning and exhibited surprisingly high ductility in air, but was susceptible to severe intergranular stress corrosion cracking (IGSCC) at high ECP. Low levels of dissolved O and ECP were effective in suppressing the susceptibility of the heavily irradiated material to IGSCC, indicating that the stress corrosion process associated with irradiation-induced grain-boundary Cr depletion, rather than purely mechanical separation of grain boundaries, plays the dominant role. However, although IGSCC was suppressed, the material was susceptible to dislocation channeling at a low ECP, and this susceptibility led to a poor work-hardening capability and low ductility.

The electrosleeve, which is nanocrystalline pure nickel, loses its strength at temperatures greater than 400 degree C during severe accidents because of grain growth. A grain growth model and the Hall-Petch relationship were used to calculate the loss of flow stress as a function of time and temperature during the accident. Available tensile test data, as well as high-temperature failure tests, on notched electrosleeved tube specimens were used to derive the basic parameters of the failure model. The model was used to predict the failure temperatures of electrosleeved tubes with throughwall and part-throughwall axial cracks in the parent tube during a postulated severe accident transient.

Degenerate PCR primers based on published sequence information gave internal gene fragments homologous to known DKGRs. Nested primers specific for the internal fragments were combined with random primers to amplify flanking gene fragments from the environmental DNA, and two hypothetical full-length genes were predicted from the combined sequences. Based on these predictions, specific primers were used to amplify the two complete genes in single PCRs. These genes were cloned and expressed in Escherichia coli. The purified gene products catalyzed the reduction of 2,5-diketo-D-gluconic acid to 2-keto-L-gulonic acid. Compared to previously described DKGRs isolated from Corynebacterium spp., these environmental reductases possessed some valuable properties. Both exhibited greater than 20-fold-higher k sub(cat)/Km values than those previously determined, primarily as a result of better binding of substrate. The Km values for the two new reductases were 57 and 67 mu M, versus 2 and 13 mM for the Corynebacterium enzymes. Both environmental DKGRs accepted NADH as well as NADPH as a cosubstrate; other DKGRs and most related aldo-keto reductases use only NADPH. In addition, one of the new reductases was more thermostable than known DKGRs.

Emissions of sulfur dioxide (SO sub(2)) and nitrogen oxides (NO sub(x)) have been increasing steadily, as nations strive to increase their levels of economic development. Coal and fuel oil have been the main choices for powering industrial development; and, until recently, only a few countries had taken steps to avert the atmospheric emissions that accompany fuel combustion. This paper discusses trends in emissions of SO sub(2) and NO sub(x) that have occurred in Asian countries in the period 1985-1997, using results from the RAINS-Asia computer model and energy-use trends from the IEA Energy Statistics and Balances database. Emissions of SO sub(2) in Asia grew from 26.6 Tg in 1985 to 33.7 Tg in 1990 and 39.2 Tg in 1997. Though SO sub(2) emissions used to grow as fast as fossil-fuel use, recent limitations on the sulfur content of coal and oil have slowed the growth. The annual-average emissions growth between 1990 and 1997 was only 2.2%, considerably less than the economic growth rate. Emissions of NO sub(x), on the other hand, continue to grow rapidly, from 14.1 Tg in 1985 to 18.7 Tg in 1990 and 28.5 Tg in 1997 (6.2% per year between 1990 and 1997), with no signs of abating. Thus, though SO sub(2) remains the major contributor to acidifying emissions in Asia, the role of NO sub(x) will become more and more important in the future.

AN - 71098474; 11483004 AB - Expression of the human apoptosis modulator protein Bax in Escherichia coli is highly toxic, resulting in cell lysis at very low concentrations (Asoh, S., et al., J. Biol. Chem. 273, 11384-11391, 1998). Attempts to express a truncated form of murine Bax in the periplasm by using an expression vector that attached the OmpA signal sequence to the protein failed to alleviate this toxicity. In contrast, attachment of a peptide based on a portion of the E. coli cochaperone GroES reduced Bax's toxicity significantly and allowed good expression. The peptide, which was attached to the N-terminus, included the amino acid sequence of the mobile loop of GroES that has been demonstrated to interact with the chaperonin, GroEL. Under normal growth conditions, expression of this construct was still toxic, but generated a small amount of detectable recombinant Bax. However, when cells were grown in the presence of 2% ethanol, which stimulated overproduction of the molecular chaperones GroEL and DnaK, toxicity was reduced and good overexpression occurred. Two-dimensional gel electrophoresis analysis showed that approximately 15-fold more GroES-loop-Bax was produced under these conditions than under standard conditions and that GroEL and DnaK were elevated approximately 3-fold.

It is a major challenge to assemble a simulation system that can successfully capture the dynamics of complex ecological systems and an even more serious challenge to be able to adapt such a simulation to shifting and expanding analytical requirements and contexts. The dynamic information architecture system (DIAS) is a flexible, extensible, object-based framework for developing and maintaining complex simulations. DIAS supports simulations in which the real-world entities that make up ecological systems are represented as software `entity objects'. The object-oriented integrated dynamic landscape analysis and modeling system (OO-IDLAMS) provides a good example of how DIAS has been used to build a suite of models for the purpose of assessing the ecological impacts of military land use and land management practices. OO-IDLAMS is a prototype conservation modeling suite that provides military environmental managers and decision-makers with a strategic, integrated and adaptive approach to natural resources planning and ecosystem management. The OO-IDLAMS prototype used Fort Riley, Kansas as a case study to demonstrate DIAS' capabilities to offer flexibility, interprocess dynamics and cost-effective reuse of code for ecosystem modeling and simulation. DIAS can also readily lend itself to other applications in ecological risk assessment. It has great potential for the integration of ecological models (associated with biological uptake and effects) with environmental fate and transport models. A DIAS ecological risk assessment application could be used to predict the magnitude and extent of ecological risks and evaluate remedy effectiveness in a timely and cost-effective manner.

At the same time, federal and state governments are promoting the use of alternative fuel vehicles as a means to curb local air pollution. As yet, the impact of this movement toward alternative fuels with respect to toxic emissions has not been well studied. The purpose of this paper is to compare toxic emissions from vehicles operating on a variety of fuels, including reformulated gasoline (RFG), natural gas, ethanol, methanol, liquid petroleum gas (LPG), and electricity. This study uses a version of Argonne National Laboratory's Greenhouse Gas, Regulated Emissions, and Energy Use in Transportation (GREET) model, appropriately modified to estimate toxic emissions. The GREET model conducts a total fuel-cycle analysis that calculates emissions from both downstream (e.g., operation of the vehicle) and upstream (e.g., fuel production and distribution) stages of the fuel cycle. We find that almost all of the fuels studied reduce 1,3-butadiene emissions compared with conventional gasoline (CG). However, the use of ethanol in E85 (fuel made with 85% ethanol) or RFG leads to increased acetaldehyde emissions, and the use of methanol, ethanol, and compressed natural gas (CNG) may result in increased formaldehyde emissions. When the modeling results for the four air toxics are considered together with their cancer risk factors, all the fuels and vehicle technologies show air toxic emission reduction benefits.

The crystals were initially grown undoped, but later Dy was added to the flux without any other charge-compensating species. With Dy and P added, in equal molar proportions, the zircon crystals incorporated 1.37 mol% (6.99 wt%) Dy and 1.36 mol% (1.33 wt%) P, a factor of 5.3 increase in Dy over the crystals grown without P intentionally added to the flux. The other P+REE-doped zircon crystals displayed an approximately 1000-fold increase in REE and P from La through Lu, a result of decreasing ionic radii. The incorporation of P (super 5+) allowed, in a general sense, the xenotime-type coupled substitution of (REE (super 3+) , Y (super 3+) )+P (super 5+) = Zr (super 4+) +Si (super 4+) . From La to Nd, however, P exceeds REE, from Sm to Gd, the REE are generally equal to P, and from Tb to Lu the REE exceed P. The Y- and P-doped zircon behaved more like middle-REE (MREE)-doped zircon than heavy-REE (HREE)-doped zircon crystals in their ability to incorporate Y (and P) and to maintain charge neutrality. To investigate the incorporation of Dy with no P added to the flux, the P to LREE excess, and the HREE to P excess in the doped zircon, secondary ion mass spectrometry (SIMS) analyses were completed on selected crystals. In the Dydoped crystals, the SIMS analyses revealed minor amounts of P, Li, and Mo in the crystals. These elements contributed to charge balance required by the excess Dy. In REE-and P-doped zircon, the SIMS analyses detected Li and Mo, and the Li and Mo may also provide charge balance for excess REE in the HREE+P-doped crystals.

REE are incorporated into the Zr site in the zircon structure, and some Zr appears to be displaced to the Si site. Crystals doped with middle REE (MREE, Sm to Dy) and Y, plus P follow the xenotime substitution (REE (super 3+) +P (super 5+) = Zr (super 4+) +Si (super 4+) ) rather closely, whereas crystals doped with heavy REE (HREE, Er to Lu) deviate from the xenotime substitution, having REE:P atomic ratios significantly greater than one. Xenotime substitution requires that P (super 5+) replace Si (super 4+) , but this substitution becomes limited by strain at the Si site in HREE-doped crystals. As Si sites become saturated with P (super 5+) , additional charge balance in synthetic zircon crystals may be provided by Mo (super 6+) and Li (super +) from the flux entering interstitial sites, accounting for an additional 0.3 to 0.6 at% HREE beyond that balanced by P (super 5+) ions. Heavy REE are more compatible in the zircon structure than are LREE and MREE, and HREE substitution is ultimately limited by the inability of the zircon structure to further accommodate charge-compensating elements. Thus the limit on REE concentrations in zircon is not a simple function of REE (super 3+) ionic radii but depends in a complex way on structural strain at Zr and Si sites, which act together to limit REE and P incorporation. The mechanisms that limit the coupled xenotime substitution change from LREE to HREE. This change means that REE fractionation in zircon may vary according to the availability of charge-compensating elements. REE partition coefficients between zircon and melt must also depend in part on the availability of charge-compensating elements and their compatibility in the zircon structure.

Estimated chlorophyll concentrations started to increase rapidly on June 2, peaked at two or three times background levels in mid-June, and subsided rapidly by early July. The chlorophyll peak appears simultaneously throughout the open waters of southern basin, an area of almost 25,000 km super(2), which suggests that the bloom resulted from a basin-wide phenomenon. Concurrent meteorological and thermister records show that a moderately strong, though brief, storm occurred on June 2 and caused a considerable deepening of the thermocline that lasted for several weeks. The decline in estimated chlorophyll concentration coincides with the strengthening of stratification and seasonal isolation of the epilimnion. It appears that this short bloom accounts for a considerable fraction of the year's algal primary production in southern Lake Michigan and that the bloom itself was triggered by a transient meteorological event that happened to occur when the lake was at a critical point in its annual thermal cycle.

The method has three key features. First, DNA to be amplified is enriched at gel pads by its hybridization with immobilized primers. mSecond, different sets of specific primers are immobilized within various gel pads, and primers are detached within gel pads just before polymerase chain reaction to enhance the amplification. A gel pad may contain an additional permanently immobilized dormant primer that is activated to carry out the allele-specific primer extension reaction to detect mutations. Third, multiple polymerase chain reactions are confined within nanoliter gel pads covered and separated from each other with mineral oil. The method was applied to simultaneously identify several abundant drug-resistant mutations in three genes of Mycobacterium tuberculosis.

In RCs from all species, the electrochromic response of the bacteriopheophytin cofactors associated with Q super(-) sub(A)Q sub(B) arrow right Q sub(A)Q super(-) sub(B) electron transfer is slowed in the presence of Cu super(2+). This slowing is similar to the metal ion effect observed for RCs from Rb. sphaeroides where Zn super(2+) was bound to a specific site on the surface of the RC [Utschig et al. (1998) Biochemistry 37, 8278]. The coordination environments of the Cu super(2+) sites were probed with electron paramagnetic resonance (EPR) spectroscopy, providing the first direct spectroscopic evidence for the existence of a second metal site in RCs from Rb. capsulatus and Rps. viridis. In the dark, RCs with Cu super(2+) bound to the surface exhibit axially symmetric EPR spectra. Electron spin echo envelope modulation (ESEEM) spectral results indicate multiple weakly hyperfine coupled super(14)N nuclei in close proximity to Cu super(2+). These ESEEM spectra resemble those observed for Cu super(2+) RCs from Rb. sphaeroides [Utschig et al. (2000) Biochemistry 39, 2961] and indicate that two or more histidines ligate the Cu super(2+) at the surface site in each RC. Thus, RCs from Rb. sphaeroides, Rb. capsulatus, and Rps. viridis each have a structurally analogous Cu super(2+) binding site that is involved in modulating the Q super(-) sub(A)Q sub(B) arrow right Q sub(A)Q super(-) sub(B) electron-transfer process. Inspection of the Rps. viridis crystal structure reveals four potential histidine ligands from three different subunits (M16, H178, H72, and L211) located beneath the Q sub(B) binding pocket. The location of these histidines is surprisingly similar to the grouping of four histidine residues (H68, H126, H128, and L211) observed in the Rb. sphaeroides RC crystal structure. Further elucidation of these Cu super(2+) sites will provide a means to investigate localized proton entry into the RCs of Rb. capsulatus and Rps. viridis as well as locate a site of protein motions coupled with electron transfer.

Organic modified clays derived from the reactions of montmorillonite (containing 93-95% montmorillonite from a bentonite, <1% quartz, and 4-6% opal CT) with octadecyltrichlorosilane (C (sub 18) H (sub 37) SiCl (sub 3) ) and octadecyltrimethoxysilane [C (sub 18) H (sub 37) Si(OMe) (sub 3) ] are highly hydrophobic. Surface loadings of the modified clays depend on the organosilane and the solvent, and they range from 10 to 25 wt. %. The organic species are probably adsorbed to the outer surfaces and bound to the edges of the clay via condensation with edge-OH groups. Encapsulation of montmorillonite with C (sub 18) H (sub 37) SiCl (sub 3) and C (sub 18) H (sub 37) Si(OMe) (sub 3) resulted in a hydrophobic coating that acts like a "cage" around the clay particles to limit diffusion. Basal spacings of the organic modified clays remain at approximately 15 Aa upon heating to 400 degrees C in N (sub 2) , whereas those of unmodified clays collapse to approximately 10 Aa. A considerable reduction in surface area (by 75-90%) for organic modified clays is observed, which is consistent with the existence of a surface coating. The solvent used can affect the amount of organic silane coated on the clay particles, whereas the difference between the products prepared using C (sub 18) H (sub 37) SiCl (sub 3) and C (sub 18) H (sub 37) Si(OMe) (sub 3) in the same solvent is relatively small. The carbon and oxygen K-edge NEXAFS spectroscopy of the modified montmorillonite surfaces showed that surface coatings on the outside of the clay particles exist. The encapsulating system may allow for economical remediation and storage of hazardous materials.

The US Environmental Protection Agency (EPA) is presently developing regulations to limit the influence of transported ozone on areas that are having difficulty meeting the ambient air quality standard. EPA has proposed stringent control measures for emissions of nitrogen oxides (NO sub(x)) in 22 states of the eastern US. The strategy would necessitate the use of selective catalytic reduction or similar high-performance technology on almost all major power plants in the region, as well as extensive controls on industrial sources. This paper suggests several alternative approaches that would achieve equal or better environmental improvement at lower cost. These include focusing control efforts on sources closer to the North-east Corridor, pushing controls on close-in sources to a higher level of technology performance, and relaxing the stringency of requirements for states remote from ozone problem areas. All the approaches examined are two to three times more cost-effective than EPA's proposed approach in the North-east Corridor.

Concern has been expressed that anthropogenic radioisotopes may have been released at some of the study areas, with the potential of posing health risks to human or ecological receptors. This concern was addressed by thoroughly searching archival records, sampling and analyzing environmental media, and performing an aerial radiation survey. The aerial radiation survey techniques employed have been used over all U.S. Department of Energy and commercial reactor sites. Use of the Aerial Measurement System (AMS) allowed investigators to safely survey areas where surveys using hand-held instruments would be difficult to perform. In addition, the AMS delivered a full spectrum of the measured gamma radiation, thereby providing a means of determining which radioisotopes were present at the surface. As a quality check on the aerial measurements, four ground truth measurements were made at selected locations and compared with the aerial data for the same locations. The results of the survey revealed no evidence of surface radioactive contamination. The measured background radiation, including the cosmic contribution, ranged from 4 to 11 mu R/h.

Recently, Fein et al. (1997) developed a chemical equilibrium approach to quantify metal adsorption onto cell walls, treating the sorption as a surface complexation phenomenon. However, such models are based on circumstantial bulk adsorption evidence only, and the nature and mechanism of metal binding to cell walls for each metal system have not been determined spectroscopically. The results of XAFS measurements at the Cd K-edge and U L3-edge on Bacillus~subtilis exposed to these elements show that, at low pH, U binds to phosphoryl groups while Cd binds to carboxyl functional groups.

Opponents of hydro power development have created and published volumes of information, often critical of the resource. But what are the facts? Knowledgeable, objective people realise that any source of energy, even renewable energy, has a consequence; either technical, environmental or social/economic in nature. Hydro power is no different to any other renewable; only its consequences are different. The Implementing Agreement on Hydropower Technologies and Programmes of the International Energy Agency (IEA), has recognised the need for balanced information and has recently implemented a programme on public awareness of hydro power. This initiative is designed to develop and bring to the public debate balanced information on a wide array of topics associated with hydro power. Phase II of the Implementing Agreement on hydro power began in May 2000 and the executive committee has adopted public awareness as a strategic initiative. A strategic awareness annex has been created and is moving forward in developing and implementing public awareness of hydro power. The challenges to creating a public awareness network are significant. To meet those challenges participants have established four objectives.

Water from this basin, the second largest in South Korea, supports a total population of more than 13 million people. Rapid industrial expansion, urbanization, and population growth have dramatically increased the demand for water and have severely degraded water quality, particularly near large industrial complexes and in the lower portion of the basin. Management strategies for the entire basin through to the year 2011 were evaluated with a computer model for basin-wide predictions of water flow and quality (HSPF). This continuous-event model was developed and calibrated using site-specific data for the basin over a two-year period (1994-1995) that included periods of both high (monsoonal) and low (drought) flows. Water quality impacts for different wastewater treatment strategies were assessed in terms of biochemical oxygen demand (BOD), nitrogen (N) and phosphorous (P) levels. The results of the study indicate that BOD levels in the main stem of the Nakdong River below the Kumhogang (a major tributary with low flow and heavy pollution loads) cannot be significantly improved by reducing direct BOD loads from point sources along the river. To reduce main stem BOD levels, the nutrient loading to the river must be reduced. In order to reduce these loads, additional advanced treatment methods (i.e., tertiary treatment) must be incorporated in the treatment facilities to remove N and P. The discharge inventory data further suggest that a large portion of N and P loads are derived from non-point agricultural practices. Reduction of these loads is difficult to accomplish and may require extensive modifications in agricultural and land-use practices. The modeling framework developed provides a means to evaluate these and other basin management strategies.

The sampler consists of a Viton diaphragm pump; a differential-pressure flow controller; a 2-position, 3-port valve; a 10-port multiposition valve; and a digital valve sequence programmer that controls the sequence and timing of the electrically actuated valves. All connecting tubing was constructed from Silcosteel tubing. Two configurations of the automated sampler and a passive collection system were evaluated by comparing the combined sampling precisions of the three systems with the analytic precision, derived from replicate analyses of an ambient air sample. The analytic precision was generally < +/- 5%, with higher values observed for analytes with mixing ratios in the tens of pptv. However, analytic precision values for methanol and ethanol were poor, greater than +/- 20%. Values for sampling precision were greater by about a factor of 2 than the analytic precision. The poor results for the light oxygenated hydrocarbons could be caused by sorption of the analytes in the preconcentration and sampling systems and difficulties in peak integration.

Analyses were performed on native coals directly, or fractions isolated by sink--float techniques. Mineral phases of kaolinite, quartz, and illite-montmorillinite clays could readily be distinguished nonquantitatively by (super 29) Si NMR techniques using direct detection or cross polarization. (super 27) Al NMR was used to determine quantitatively the amounts of tetrahedral and octahedral aluminum forms present. The (super 27) Al NMR results were consistent with mineralogical analyses by XRD, showing that increases in tetrahedral content paralleled illitization of the clay minerals. A remarkably good relationship also was found between the total amount of tetrahedral aluminum associated with the mineral matter and degree of maturation of the organic matter in the coal. The data suggest that illitization of the clays can be used as a mineralogical thermal maturity indicator for Type II kerogens, as demonstrated for the Argonne Premium coals, provided that contributions from organo-chelated aluminum species and detrital mineral matter are taken into account.

The minicolumn combines a guanidine thiocyanate method of nucleic acid isolation with a newly developed hydroxyl radical-based technique for DNA and RNA labeling and fragmentation. DNA and RNA can also be fractionated through differential binding of double- and single-stranded forms of nucleic acids to the silica. The procedure involves sequential washing of the column with different solutions. No vacuum nitration steps, phenol extraction, or centrifugation is required. After hybridization, the overall fluorescence pattern is captured as a digital image or as a Polaroid photo. This three-component system was used to discriminate Escherichia coli, Bacillus subtilis, Bacillus thuringiensis, and human HL60 cells. The procedure is rapid: beginning with whole cells, it takes approximately 25 min to obtain labeled DNA and RNA samples and an additional 25 min to hybridize and acquire the microarray image using a stationary image analysis system or the portable imager.

Spatial variations of aliphatic hydrocarbons in surficial sediments were consistent with a lakeward movement of riverine sediments in a series of resuspension-settling cycles in which an unresolved complex mixture (UCM) of hydrocarbons associated with dense sediments is deposited in nearshore areas, fine-grained sediments of terrestrial origin accumulate in the deep basin, and planktonic hydrocarbons are depleted by microbial degradation during transport to the deep basin. The rate of accumulation of the UCM (a marker of petroleum residues) in deep basin sediments has increased by more than an order of magnitude since 1880, from 60 mu g m super(-2) times a super(-1) to approximately 960 mu g m super(-2) times a super(-1) in 1980. Crude estimates of the atmospheric loading of the UCM (1100 mu g m super(-2) times a super(-1)) indicate that accumulations in deep-basin sediments might be supported by atmospheric deposition. Agreement was poor between the atmospheric flux of the terrestrial n-alkanes ( capital sigma C sub(25), C sub(27), C sub(29), C sub(31)) to the deep basin (3200 mu g m super(-2) times a super(-1)) and the sediment accumulation rate (660 mu g m super(-2) times a super(-1)). Understanding of atmospheric fluxes, estimated from the very few available data, would be improved by more frequent measurement of the levels of aliphatic hydrocarbons in air and precipitation and a better knowledge of the particle deposition velocities and precipitation scavenging coefficients.

AN - 70963334; 11428134 AB - A method is described for near-quantitative extraction of micromolar concentrations of chlorinated aliphatic hydrocarbons (CAHs) from water for determination of chlorine (Cl) isotope ratios. A low pressure, carrier-gas procedure of extraction was proven to be applicable to CH2Cl2, CCl4, C2H2Cl2, and C2HCl3. The pH of the water was adjusted with NaOH to prevent extraction of CO2 from air and/or dissolved inorganic carbonate species. Recoveries of CAH samples (approximately 15 mumol), added to and extracted from approximately 340 ml of water, averaged approximately 96%. Average changes in the delta 37Cl values of the CAHs, attributable to the extraction process, were -0.01 +/- 0.06@1000. Significant isotopic fractionation of Cl was measured during partial extraction of C2CHCl3 from water, indicating that near-quantitative extraction is required for reliable stable Cl isotope analysis of CAHs. This method is also suitable for the extraction of dissolved CAH for gas chromatography-combustion-isotope ratio mass spectrometric measurements of hydrogen and carbon.

Activities of ( (super 228) Ra) and ( (super 226) Ra) were analyzed in fresh and saline ground waters, brines, and rocks. The fluids have a wide salinity range (200-250,000 mg l (super -1) total dissolved solids). The ( (super 226) Ra) activity ranges from 0.66-7660 dpm kg (super -1) and correlates with salinity and other alkaline earth element (Ca, Sr, and Ba) concentrations. The range of ( (super 228) Ra: (super 226) Ra) ratios in the fluids (0.06-1.48) is similar to that in the aquifer rocks (0.21-1.53). The relatively low mean fluid ( (super 228) Ra: (super 226) Ra) ratio (0.30) reflects the low Th:U ratio of the predominant carbonate aquifer rock. Radium occurs mostly (> or =77%) as Ra (super 2+) species in the fluids. Salinity-dependent sorption-desorption processes (with log K values from 10 (super 0) -10 (super 4) and negatively correlated with salinity), involving Th-enriched surface coatings on aquifer flow channels, can explain the rapid solid-fluid transfer of Ra isotopes in the system and the correlation of Ra with salinity.

We investigated the future effects of the Tushka Canal project on the Nubian Aquifer and on the saline water intrusion in the central delta. A 2-dimensional groundwater flow model was built and calibrated against observed data by accounting for the transient recharge caused by intensive lake fluctuations during the calibration period (1970-2000). The simulation results indicate: (1) The recharge front from the lake is expected to advance northwestward at an average rate of 0.1-0.4 km/yr without posing flooding risks for the irrigation areas. (2) The pumping/injection rates expected in the project will cause no major impacts, except for the formation of some local cones of depression and ground water mounds. (3) Irrigation recharge will complicate the groundwater flow by introducing the modern lake waters and could potentially cause flooding and salinization in the vicinity of the proposed irrigation areas. A two-dimensional density-dependent groundwater flow and solute transport model (FEMWATER; Lin et al., 1997) was used to simulate the effects of increased extraction of the Nile aquifer groundwater and decreased recharge resulting from the diversion of Nile water through the Tushka Canal on the salt water intrusion in the central delta aquifer. The current understanding is that extraction in the southern and central delta is less likely to produce major changes in salinity distribution. Our simulation results, however, indicate that the projected extraction could potentially increase the concentration of the total dissolved solids by up to 1000 ppm in the study area over the next ten years.

The output of these models has usually been validated by comparison with paleoclimate indicators, such as coals, tillites, or evaporite deposits. However, these model/data comparisons are usually far from rigorous. Most comparisons have relied on subjective visual interpretations (i.e., comparing by ?eye?) for several reasons. First of all, model performance can vary spatially on both global and regional scales, so that climate predictions may be highly generalized. Second, paleoclimate indicators could be formed by processes not considered within general circulation models. For example, GCM?s do not include regional drainage, an important aspect of soil formation, and thus would not be able to accurately predict the spatial distribution of key soil types. Third, although the boundary conditions of climate change at multiple scales, each climate model run represents only a single climate state. In contrast, paleoclimate indicators are time averaged and thus can incorporate multiple states, including extreme conditions. Finally, the definition of what constitute a ?match? between model results and indicators is also problematic. Most paleoclimate indicators are defined in general terms, such as hot and seasonally wet, but such definitions are difficult to assess against the more precise climate models. Model/data comparisons have thus generally been qualitative rather than quantitative. New approaches are clearly needed to improve climate model/data comparisons. We are addressing this issue using the distribution of evaporites as a test case. Evaporites are generally defined as forming in warm and dry regions that are seasonally wet. In reality, a wide variety of conditions can lead to evaporite formation. We are producing a quantitative calibration of the occurrence of recent evaporites against a climate model for modern boundary conditions. This calibration is then used to produce a predictive relationship between climate variables and evaporite formation. Models of ancient climates can then be used to predict evaporite occurrence in the geologic past. The predicted distributions are then compared with known occurrences to validate the approach.

These data indicate that the residual double bond present in mature Class I ambers is not located in the A/B ring structure of these materials and that C17 of the original labdanoid precursors is retained in mature Class I ambers as a methyl group. These data also suggest that the reaction which results in formation of the residual unsaturated structure in mature ambers also results in a second covalent connection between the A/B ring system and the polymer backbone, probably through C8 of the original labdanoid structure.

Comparisons were made between inferences made from ASTER images and TM images acquired over the same area and during the same season. In the study area, three terranes are juxtaposed: the Kohistan terrane, the Karakoram terrane, and the Hindukush terrane and a compositionally diverse suite of rock units are exposed. These include clastic, carbonate and low grade metamorphic rocks of the Hindukush terrane, Karakoram Batholith, paragneiss, Triassic limestone and the young clastic sediments of the Purit Formation of the Karakoram terrane, arc volcanic and plutonic rocks of the Kohistan terrane and rocks of the Shyok Suture melange. The selected scenes were acquired in the summer season (July/August 2000) to minimize spectral interference from snow and clouds. Vegetative cover is minimal except in the valleys. The first three of the ASTER bands have a higher spatial resolution (15 m) than the Landsat TM (30 m) images and thus provide detailed topographical and geological information. The locations of the suture zones between the Kohistan terrane, the Karakoram plate, and the Hindukush terrane are readily discernable on the ASTER data but not as well on the Landsat TM images. Similarly, faults (e.g., Reshun Fault) are also visible in ASTER data. The relatively large number of bands (14) and the longer wavelength regions (VIR 0.520-0.860, SWIR 1.600-2.430 and TIR 8.125-11.650 micrometer) covered by the ASTER data allows discrimination between a wide range of compositions that are not readily recognized from the TM data. These include carbonate, and adjoining sedimentary units, mafic and ultramafic rocks of Shyok Suture melange, the dioritic batholiths in Kohistan and Karakoram, and the volcanic rocks of the Kohistan terrane. The latter are mafic to intermediate in compositions. ASTER data was found to be useful for lithologic and structural investigations of this highly remote and inaccessible area of northern Pakistan. Implications for similar applications elsewhere are clear.

Complex hydrogeological conditions and the transient water use rates of trees require the application of numerical modeling to address such issues as hydraulic containment, seasonality, and system design. In 1999, 809 hybrid poplars and willows were planted to phytoremediate the 317 and 319 Areas of Argonne National Laboratory near Chicago, Illinois. Contaminants of concern are volatile organic compounds and tritium. The site hydrogeology is a complex framework of glacial tills interlaced with sands, gravels, and silts of varying character, thickness, and lateral extent. A total of 420 poplars were installed using a technology to direct the roots through a 25-ft (8-m)-thick till to a contaminated aquifer. Numerical modeling was used to simulate the effect of the deep-rooted poplars on this aquifer of concern. Initially, the best estimates of input parameters and boundary conditions were determined to provide a suitable match to historical transient groundwater flow conditions. The model was applied to calculate the future effect of the developing deep-rooted poplars over a 6 year period. The first 3 years represent the development period of the trees. In the fourth year, canopy closure is expected to occur; modeling continues through the first 3 years of the mature plantation. Monthly estimates of water use by the trees are incorporated. The modeling suggested that the mature trees in the plantation design will provide a large degree of containment of groundwater from the upgradient source areas, despite the seasonal nature of the trees' water consumption. The results indicate the likely areas where seasonal dewatering of the aquifer may limit the availability of water for the trees. The modeling also provided estimates of the residence time of groundwater in the geochemically altered rhizosphere of the plantation.

Hundreds of these sites were used for research and production in support of the national defense mission, including facilities managed by and for the U.S. Department of Energy. An extensive federal cleanup program is underway to develop appropriate environmental management responses for these facilit following the general framework developed by the U.S. Environmental Protection Agency (EPA) for Superfund sites. Risks estimated for the public, workers, and ecological resources as part of this EPA framework are intended to serve as input to the overall cleanup plans. Methods and data exist to predict risks for workers involved in common cleanup activities, such as excavation and transportation of wastes for disposal. While worker risks have not often been the driving factor in determining whether active cleanup measures are taken, in certain cases, results of the worker risk analyses have been used to guide the response actions and develop activity-specific protection plans. This paper identifies approaches used to estimate worker risks and illustrates ways to present the results in a manner that can effectively inform cleanup decisions.

Intergenerational equity refers to the fairness of access to resources across generations. Environmental restoration cleanup levels can have unintended and unfair consequences for future generations' access to resources. The potentially higher costs associated with using low, non-risk-based cleanup levels for remediation may divert funding from other activities that could have a greater beneficial impact on future generations. Low, non-risk-based cleanup levels could also result in more damage to the nation\""s resources than would occur if a higher cleanup level were used. The loss or impairment of these resources could have an inequitable effect on future generations. However, intergenerational inequity could arise if sites are not completely restored and if access to and use of natural and cultural resources are unfairly limited as a result of residual contamination. In addition to concerns about creating possible intergenerational inequities related to selected cleanup levels, the tremendous uncertainties associated with sites and their restoration can lead site planners to rely on stewardship by default. An ill-conceived stewardship program can contribute to intergenerational inequity by limiting access to resources while passing on risks to future generations and not preparing them for those risks. This paper presents a basic model and process for designing stewardship programs that can achieve equity among generations.

The primary use of the detector is in a three-dimensional (3-D) computed tomography (CT) system. The detector is a two- dimensional (2-d) flat panel array consisting of a 1024 \times 1024 matrix of photodiodes placed on a 100-\mum center. Combined with a Lanex(tm) scintillator, the detector-sensor presents an ideal solution for high-resolution industrial X-ray imaging applications. Modulation transfer function (MTF), determined from a 2-D projection image of a line-pair phantom, shows that the detector can achieve a resolution of 140 \mum at 50% contrast, and a resolution of approximately one pixel (100 \mum) at 20% of maximum image contrast. Further, examination of monolithic ceramic material with projection data from this detector demonstrates that such a flat-panel detector has promise for use in a CT system to provide highly resolved information. The reconstructed CT image of a ceramic hole-phantom demonstrates that the smallest holes (with a diameter of 300 \mum) can be detected with a spatial resolution of \sim 150 \mum at 50% contrast.

PASS-generated estimates of bulk canopy stomatal resistance were used in a dry deposition module to compute gas deposition velocities with a horizontal resolution of 200 m for approximately 5000 km super(2) of agricultural crops and rangeland. Results were compared with measurements of O sub(3) flux and concentrations made during April and May 1997 at two surface stations and from an aircraft. The trend in simulated O sub(3) deposition velocity during soil moisture drydown over a period of a few days matched the trend observed at the two surface stations. For areas under the aircraft flight paths, the variability in simulated O sub(3) deposition velocity was substantially smaller than the observed variability, while the averages over tens of kilometers were usually in agreement within 0.1 cm s super(-1). Model results indicated that soil moisture can have a major role in deposition of O sub(3) and other substances strongly affected by canopy stomatal resistance.

In particular, a major issue associated with a contaminated structure is whether there is a realistic potential for future use of the structure. This issue should be addressed early in a planning process. The resolution of this issue significantly affects other major issues associated with management of a contaminated structure such as: (1) What are the expected costs associated with management of the structure?

The mutant carries out a balanced fermentation of glucose to give approximately 1 mol of succinate, 0.5 mol of acetate, and 0.5 mol of ethanol per mol of glucose. The causative mutation was mapped to the ptsG gene, which encodes the membrane-bound, glucose-specific permease of the phosphotransferase system, protein EIICB super(glc). Replacement of the chromosomal ptsG gene with an insertionally inactivated form also restored growth on glucose and resulted in the same distribution of fermentation products. The physiological characteristics of the spontaneous and null mutants were consistent with loss of function of the ptsG gene product; the mutants possessed greatly reduced glucose phosphotransferase activity and lacked normal glucose repression. Introduction of the null mutant into strains not blocked in the ability to ferment glucose also increased succinate production in those strains.

HPSEC systems often use a variable wavelength UV-vis detector, which detects the analytes based upon their chromophoric composition. HS contain a range of moieties with chromophores having unique molar absorptivities (for a given wavelength), and the calculated MW may be dependent upon the wavelength chosen for the analysis. As a consequence, the choice of wavelength becomes an important parameter for the reliable determination of MW by HPSEC. The effect of UV-vis detector wavelength on the determination of the MW distribution of selected humic and fulvic acids by HPSEC is examined in this paper. For the HS examined, both the number (M sub(n)) and weight average (M sub(w)) MW increased with increasing wavelength. The relative increase in MW was most pronounced for Lake Fryxell fulvic acid, with a 63 and 21% increase in M sub(n) and M sub(w), respectively, between 220 and 380 nm. The increases observed for Suwannee River humic and fulvic acids were less pronounced. M sub(n) was more sensitive to changes in detector wavelength than M sub(w), and as a result the target HS appeared to be less polydisperse at higher wavelengths. Within the range of wavelengths commonly used for the determination of MW of HS by HPSEC (i.e., 220-280 nm), the magnitude of the increases in MW was not significant compared to variability in MW that results from changes to other operational parameters in HPSEC.

The natural or unperturbed component is equivalent to that part of the atmospheric CO (sub 2) distribution which is controlled by non-anthropogenic CO (sub 2) fluxes from the ocean and terrestrial biosphere. Models should be able to reproduce the true north-south gradient in CO (sub 2) due to the natural component before they can reliably estimate present-day CO (sub 2) sources and sinks and predict future atmospheric CO (sub 2) . We have estimated the natural latitudinal distribution of atmospheric CO (sub 2) , relative to the South Pole, using measurements of atmospheric CO (sub 2) during 1959-1991 and corresponding estimates of anthropogenic CO (sub 2) emissions to the atmosphere. Key features of the natural latitudinal distribution include: (1) CO (sub 2) concentrations in the northern hemisphere that are lower than those in the southern hemisphere; (2) CO (sub 2) concentration differences that are higher in the tropics (associated with outgassing of the oceans) than those currently measured; and (3) CO (sub 2) concentrations over the southern ocean that are relatively uniform. This natural latitudinal distribution and its sensitivity to increasing fossil fuel emissions both indicate that near-surface concentrations of atmospheric CO (sub 2) in the northern hemisphere are naturally lower than those in the southern hemisphere. Models that find the contrary will also mismatch present-day CO (sub 2) in the northern hemisphere and incorrectly ascribe that region as a large sink of anthropogenic CO (sub 2) .

Dates of sediment lead peaks (1978 + or - 2) accord with prior observations of a 6 year lag between the occurrence of maximum atmospheric lead in 1972 and peak coral lead in 1978. Smaller lags of 1-2 years occur between the maximum atmospheric radionuclide fallout and peaks in sediment temporal records of (super 137) Cs and Pu. Such lags are consequences of system time averaging (STA) in which atmospherically delivered particle-associated constituents accumulate and mix in a (sedimentary?) reservoir before transferring to permanent sediments and coral. STA model calculations, using time-dependent atmospheric inputs, produced optimized profiles in excellent accord with measured sediment (super 137) Cs, Pu, lead, and coral lead distributions. Derived residence times of these particle tracers (16 + or - 1, 15.7 + or - 0.7, 19 + or - 3, and 16 + or - 2 years, respectively) are comparable despite differences in sampling locations, in accumulating media, and in element loading histories and geochemical properties. For a 16 year weighted mean residence time, STA generates the observed 6 year lead peak lag. Evidently, significant levels of nondegradable, particle-associated contaminants can persist in Florida Bay for many decades following elimination of external inputs. Present results, in combination with STA model analysis of previously reported radionuclide profiles, suggest that decade-scale time averaging may occur widely in recent coastal marine sedimentary environments.

Live fine root mass (LFR) showed less seasonal variation than dead fine root mass (DFR), which was correlated with seasonal changes in soil moisture and soil temperature. LFR mass increased significantly (by 86%) in the elevated CO sub(2) treatment, with an increment of 37 g(dry weight) m super(-2) above the control plots after two years of CO sub(2) fumigation. There was no long-term increment in DFR associated with elevated CO sub(2), but significant seasonal accumulations of DFR mass occurred during the summer of the second year of fumigation. Overall, root net primary production (RNPP) was not significantly different, but annual carbon inputs were 21.7 gC m super(-2) y super(-1) (68%) higher in the elevated CO sub(2) treatment compared to controls. Specific root respiration was not altered by the CO sub(2) treatment during most of the year; however, it was significantly higher by 21% and 13% in September 1997 and May 1998, respectively, in elevated CO sub(2). We did not find statistically significant differences in the C/N ratio of the root tissue, root decomposition or phosphatase activity in soil and roots associated with the treatment. Our data show that the early response of a loblolly pine forest ecosystem subject to CO sub(2) enrichment is an increase in its fine root population and a trend towards higher total RNPP after two years of CO sub(2) fumigation.

These are the first in situ measurements of the orthoclase-water interface structure performed to Angstrom-scale resolution. The orthoclase (001) cleavage surface has minimal roughness, and only one of two possible surface terminations is exposed. The X-ray data show that (1) the silica network at the orthoclase surface is terminated by an oxygen-containing species (e.g., O or OH) having a coverage of 1.9 + or - 0.25 ML (the expected coverage is 2.0 ML, where 1 ML = 1 atom/55.76 Aa (super 2) ), (2) the outermost layer of K (super +) ions have been removed with a derived coverage of 0.0 + or - 0.08 ML (the bulk truncated K (super +) coverage is 1.0 ML), and (3) a complex relaxation profile affecting the near-surface structure propagates approximately 26 Aa into the orthoclase with a maximum relaxation of approximately 0.15 Aa near the surface. These data are inconsistent with K (super +) ion depletion below the topmost K (super +) layer. These results provide a new baseline for understanding the initial steps of the feldspar dissolution process, demonstrate the power of combining X-ray scattering techniques with scanning probe microscopies for understanding the intrinsic characteristics of complex mineral-water interface systems, and suggest a new approach for understanding feldspar dissolution mechanisms.

All four models make comparable predictions for the plume centerline concentrations of the primary contaminants in the aquifer for a distance of up to about 300 m from the source. MEPAS, MMSOILS, and RESRAD make similar predictions for the transverse concentration profiles in the aquifer. The four models make considerably different predictions for the temporal concentration profiles of the progeny in the aquifer. The profiles differ in shape, magnitude of the peak, and in width. The differences are a result of the simplifying assumptions underlying each of the models.

In this paper, we report on the first use of (super 81) Kr to determine the age of groundwater from four wells in the Great Artesian Basin in Australia. As the concentration of (super 81) Kr in old groundwater is only a few hundred atoms per liter, krypton was extracted from large (16000 l) groundwater samples and was analyzed for the isotopic abundance of (super 81) Kr by accelerator mass spectrometry (AMS) with a cyclotron. (super 81) Kr/Kr isotope ratios of (1.54 + or - 0.22) X 10 (super -13) , (1.78 + or - 0.26) X 10 (super -13) , (2.19 + or - 0.28) X 10 (super -13) and (2.63 + or - 0.32) X 10 (super -13) , respectively, were measured for these samples. It is reasonable to assume that krypton dissolved in surface water in contact with the atmosphere has the known atmospheric (super 81) Kr/Kr ratio of (5.20 + or - 0.40) X 10 (super -13) . The observed reduction of isotope ratios in the groundwater samples can then be interpreted as being due to radioactive decay since recharge. This results in respective groundwater ages of: (4.02 + or - 0.51) X 10 (super 5) yr, (3.54 + or - 0.50) X 10 (super 5) yr, (2.87 + or - 0.38) X 10 (super 5) yr and (2.25 + or - 0.42) X 10 (super 5) yr. The main emphasis of this paper lies on the description of the analytic procedure to extract a reliable (super 81) Kr signal from large groundwater samples. Although the uncertainties are still relatively large (primarily due to counting statistics caused by the low cyclotron AMS efficiency), the new technique enabled for the first time a definite determination of residence times for old groundwater with (super 81) Kr. It thus confirms the hope that this radionuclide may become a very valuable tool for groundwater dating.

One of a pair of PCR primers was immobilized inside a separate microchip polyacrylamide porous gel pad of 0.1 x 0.1 x 0.02 (or 0.04) mu m in size and 0.2 (or 0.4) nL in volume. The amplification was carried out simultaneously both in solution covering the microchip array and inside gel pads. Each gel pad contained the immobilized forward primers, while the fluorescently labeled reverse primers, as well as all components of the amplification reaction, diffused into the gel pads from the solution. To increase the amplification efficiency, the forward primers were also added into the solution. The kinetics of amplification was measured in real time in parallel for all gel pads with a fluorescent microscope equipped with a charge-coupled device (CCD) camera. The accuracy of the amplification was assessed by using the melting curves obtained for the duplexes formed by the labeled amplification product and the gel-immobilized primers during the amplification process; alternatively, the duplexes were produced by hybridization of the extended immobilized primers with labeled oligonucleotide probes. The on-chip amplification was applied to detect the anthrax toxin genes and the plasmid-borne beta -lactamase gene responsible for bacterial ampicillin resistance. The allele-specific type of PCR amplification was used to identify the Shiga toxin gene and discriminate it from the Shiga-like one. The genomic mutations responsible for rifampicin resistance of the Mycobacterium tuberculosis strains were detected by the same type of PCR amplification of the rpoB gene fragment isolated from sputum of tuberculosis patients. The on-chip PCR amplification has been shown to be a rapid, inexpensive and powerful tool to test genes responsible for bacterial toxin production and drug resistance, as well as to reveal point nucleotide mutations.

Human exposure can occur as a result of handling these compounds, routine low-level effluent releases to the environment from processing facilities, or materials being accidentally released from storage locations or during processing or transportation. Exposure to uranium can result in both chemical and radiological toxicity, but in most instances chemical toxicity is of greater concern. This article discusses the chemical toxic effects from human exposure to depleted uranium compounds that are likely to be handled during the long-term management and use of depleted uranium hexafluoride (UF sub(6)) inventories in the United States. It also reviews representative publications in the toxicological literature to establish appropriate reference values for risk assessments. Methods are described for evaluating chemical toxicity caused by chronic low-level exposure and acute exposure. Example risk evaluations are provided for illustration. Preliminary results indicate that chemical effects of chronic exposure to uranium compounds under normal operating conditions would be negligibly small. Results also show that acute exposures under certain accident conditions could cause adverse chemical effects among the populations exposed.

For the case of gibbsite precipitated on a kaolinite powder substrate we demonstrate a simple method having a minimum detection limit of 0.1 wt%, using pure gibbsite as the intensity reference in mechanical mixtures of gibbsite and kaolinite. The amount of gibbsite precipitated onto kaolinite at 80 degrees C, pH 3 is higher when determined from solution chemistry than from the X-ray method, and the difference in amounts increases with increasing Al concentration in solution. This discrepancy can be explained by assuming that a fraction of the precipitated material is effectively invisible to the X-ray diffraction technique, either due to a small diffracting domain size along the gibbsite [001] direction or formation of an Al-phase that is amorphous to X-rays. This method should be generally useful for a range of mineral mixtures where at least one intense reflection for the phase of interest is not obscured. The ability to identify, characterize, and quantify trace phases by X-ray diffraction, especially when combined with surface analysis by electron or atomic force imaging, is an important complement to the conventional approach of monitoring solution composition in growth kinetics experiments.

An approach for contaminant transport model testing is calibration based on large-scale laboratory experiments. This paper is the first of two papers in which the calibration of a two-dimensional variable fracture network model for radioactive tracers is formulated as an inverse problem using a Bayes-Markov approach. This paper gives the framework for the inverse problem and describes a novel contaminant transport model appropriate for this problem. The subsequent paper presents the details of the algorithm for the inverse problem solution. The prior information for fracture aperture distribution is assumed in the form of Markov random fields (MRF). In particular, the class of auto-models has been successful in reproducing the connectivity in extreme values of fracture apertures, and experimentally observed flow channeling. A continuous model, conditional autoregressive model, and a discrete, auto-binomial model have been applied. The mathematical model for the contaminant transport in the discrete fracture network is based on the numerical inversion of the Laplace transform. This methodology is free of numerical dispersion, but requires a large number of terms to reconstruct very steep contaminant fronts.

In particular, Markov random field (MRF) models have been proposed as a priori distribution functions for fracture apertures. The fracture reconstruction is based on the a posteriori distribution function simulation using a Markov chain Monte Carlo procedure. A two-level estimation-reconstruction algorithm has been developed. On the first level, the fracture apertures are reconstructed using simulated annealing (SA), with the Metropolis-Hastings dynamics. The MRF parameters are assumed known. On the second level, after several sweeps of the entire field using SA, the MRF parameters are updated using the method of pseudolikelihood. The competing models are finally compared using an asymptotic form of the Bayes factor.

The OT-HS binding was characterized by linear isotherms. The K sub(doc) values measured in this study were several orders of magnitude greater than would be predicted based only on nonpolar interactions with HS (as estimated by K sub(ow)). Binding of tri-n-butyltin (TBT) by Aldrich humic acid decreased with increasing salinity and pH, indicating that ionic interactions predominate in TBT-HS binding. Thus, the binding of OT by HS observed in this study occurs primarily through complexation, with secondary contributions from nonpolar interactions. The effects of the physicochemical properties of HS (e.g., molecular weight, % aromaticity, oxygen content) on TBT-HS binding was examined with HS from a range of sources, including a commercial humic acid and HS from aquatic and terrestrial sources. Although binding of organic contaminants by HS has been correlated with various structural features of HS, no meaningful relationship between any of the HS properties examined in this study and the extent of TBT-HS binding was found.

This review will summarize the details for crystallization of modified hectorites along with their characterization and materials applications. Among the several potential uses of these synthetic materials, there are two important applications concerning catalysis and composites. The fate of the template dictates which of these applications is pertinent. First, if the organic molecule or polymer is used with the intention of acting as templates of pore structure, then the organic template is removed after the modified clay has been crystallized. Upon template removal, the now porous materials are examined for their use as potential catalysts and catalyst supports. We have recently proven a correlation between catalyst pore size in the mesoporous range and the size and concentration of a polymeric template that is used. Preliminary hydrodesulfurization catalytic results have been obtained using these materials. If, on the other hand, intercalants are allowed to remain as a part of the structure, then a distinctive class of organic-inorganic composites becomes possible. When polymeric intercalants are used, especially at high concentrations, the materials have relevance to nanocomposite applications. Work in this area has focused on incorporating polymers at higher than 85 wt.% of the nanocomposite.

Although long-term, incremental changes in climate can have serious consequences, it is usually the extreme, surprising events that cause the most damage to human health and property. Different taxonomies of surprise are explored, drawing from literature concerning diverse aspects of human society. Surprise is revealed to be a subjective concept in many respects, triggered by such factors as prior experience, belief systems, and media exposure. How policymakers have reacted to climate surprises in the past is considered, particularly with regard to choices made between pro-active and reactive measures. It is concluded that, while some kinds of surprise are truly unpredictable, there are other types that could be anticipated and their adverse effects forestalled.

In the initial step, a cyclic hypomanganate ester is formed via an activated organometallic complex. The initial reaction is a rate-limiting step (second-order rate constant k sub(1p) = 0.65-0.68 M super(-1) s super(-1) at 21 degree C) and independent of pH. In the second step, the decomposition of the cyclic ester with complete chlorine liberation proceeds quickly via various reaction pathways to form four carboxylic acids. Approximately 77% of the TCE was transformed to formic acid at pH 4, while 95-97% of the TCE was transformed to oxalic and glyoxylic acids at pH values of 6-8. Kinetic data suggest that the decomposition rate of the cyclic ester is at least 100 times higher than its formation rate. In the final step, all carboxylic acids are oxidized by permanganate to the final product, CO sub(2). Second-order rate constants of k sub(3ap) = 0.075-0.35 M super(-1) s super(-1), k sub(3bp) = 0.13-0.37 M super(-1) s super(-1), and k sub(3cp) = 0.073-0.11 M super(-1) s super(-1) over a pH range of 4-8 at 21 degree C were estimated for oxidation of formic, glyoxylic, and oxalic acids, respectively. The oxidation rate of carboxylic acids and accumulation rate of CO sub(2) increase with decreasing pH.

AN - 71254088; 10892727 AB - Several studies with two-dimensional gel electrophoresis (2-DE) have shown that the abundance of numerous mouse liver proteins is altered in response to treatment with chemicals known to cause peroxisome proliferation. The peptide masses from tryptic digests of two liver proteins showing dramatic decreases in abundance in response to numerous peroxisome proliferators were used to search sequence databases. The selenium-binding protein 2 (SBP2 formerly 56 kDa acetaminophen-binding protein, AP 56) and selenium-binding protein 1 (SBP1 formerly 56 kDa selenium-binding protein, SP 56) in mouse liver, proteins with a high degree of sequence similarity, were the highest ranked identities obtained. Identity with SBP2 was subsequently confirmed by immunodetection with specific antiserum. Treatment of mice with 0.025% ciprofibrate resulted in the more basic of this pair of proteins being decreased to 30% of control abundance while the acidic protein was decreased to 7% of the control amount. Dexamethasone treatment, in contrast, caused increases of 80% and 20% in the abundance of the acidic and basic forms, respectively. Administration of dexamethasone to mice in combination with ciprofibrate produced expression of the acidic SBP2 at 23% of the control level and the basic SBP2 at 36%, a slightly moderated reduction compared with the decrease that occurred with ciprofibrate alone. These data suggest that peroxisome proliferators such as ciprofibrate cause a decrease in the abundance of the SBP2, which leads to increased cell proliferation, even in the presence of an inhibitor such as dexamethasone. Such a decrease in SBP, thought to serve as cell growth regulation factors, could be central to the nongenotoxic carcinogenicity of the peroxisome proliferators observed in rodents.

Concentrations of Pb and combustion-derived PAHs in Crystal Lake sediments have increased by factors of 8 and 3, respectively, over the past 150 years. In contrast, levels of perylene increased with depth in the sediment, indicating that postdepositional formation of this PAH might be occurring. Atmospheric fluxes of anthropogenic Pb and combustion-derived PAHs were estimated to be 10,000 mu g m (super -2) a (super -1) and 34 mu g m (super -2) a (super -1) , respectively. The settling sediment fluxes of planktonic n-alkanes (Sigma C (sub 15) , C (sub 17) , C (sub 19) ) and terrestrial n-alkanes (Sigma C (sub 25) , C (sub 27) , C (sub 29) , C (sub 31) ) in Crystal Lake were 4,400 mu g m (super -2) a (super -1) and 10,500 mu g m-2 a (super -1) , respectively, whereas their accumulation rates in pelagic sediments were 270 mu g m (super -2) a (super -1) and 7,100 mu g m (super -2) a (super -1) , respectively. The large difference between the settling sediment flux and the accumulation rate of the planktonic n-alkanes in the sediments is ascribed to microbial degradation during or soon after deposition. In contrast, the terrestrial n-alkanes are incorporated in a wax matrix and are protected from degradation. The contribution of terrestrial n-alkanes to the organic carbon of the sediments has remained relatively constant over the past 150 years. About 20% of the organic carbon that is incorporated in the present-day sediments of Crystal Lake can be attributed to the deposition of pine pollen in the lake. Deforestation of the region in the late 1800s apparently caused terrigenous inputs and primary productivity of nonsiliceous plankton to increase, because planktonic and terrestrial n-alkane concentrations in the sediment increased at about the same time. However, since about 1900 concentrations of organic carbon and of terrestrial and planktonic n-alkanes in Crystal Lake sediments have decreased, and concentrations of Al and combustion-derived PAH have increased. These occurrences might reflect a decrease in pollen dispersal in the region and an increase in the atmospheric deposition of fly ash from coal-burning power plants.

We used a micro-array consisting of three-dimensional gel-elements containing all possible hexamers (total of 4096 probes). Hybridization of fluorescently labelled viral cDNA samples with such microchips resulted in a pattern of spots that was registered and quantified by a computer-linked CCD camera, so that the sequence of the original cDNA could be deduced. The method could reliably identify single point mutations, since each of them affected fluorescence intensity of 12 micro-array elements. Micro-array hybridization of DNA mixtures with varying contents of point mutants demonstrated that the method can detect as little as 10% of revertants in a population of vaccine virus. This new technology should be useful for quality control of live viral vaccines, as well as for other applications requiring identification and quantification of point mutations.

Approximately 40 NMOCs with 6-10 carbon atoms were observed in samples analyzed by high-resolution gas chromatography with the flame ionization detector. Nineteen NMOCs in this molecular weight range (6 aliphatic oxygenates; 1 aromatic hydrocarbon; and 4 acyclic, 5 monocyclic, and 3 bicyclic monoterpenoids) were identified by ion trap mass spectrometry. Mass spectrometry was particularly useful for identifying myrcene and cis-3-hexenylcetate, which coeluted on a fused-silica capillary column coated with a 1- mu m-thick film of polydimethylsiloxane. An evaluation of the reactivity of the grassland emissions revealed that the aliphatic oxygenates have lifetimes of a few hours with respect to oxidation by OH and O sub(3) in the atmosphere. This value is similar to the lifetimes of the bicyclic monoterpenoids. The expected lifetimes of the monoterpenoids with respect to oxidation by NO sub(3) are only several minutes.

USDOE established the US Center (ISINSC) at Argonne National Laboratory (ANL) in October 1995. MINATOM MINATOM established the Russian Center (RINSC) at the Research and Development Institute of Power Engineering (RDIPE) in Moscow in July 1996. In April 1998 the Russian center became a semi-independent, autonomous organization under MINATOM. The goals of the center are to: Cooperate in the development of technologies associated with nuclear safety in nuclear power engineering; Be international centers for the collection of information important for safety and technical improvements in nuclear power engineering; and Maintain a base for fundamental knowledge needed to design nuclear reactors. The strategic approach is being used to accomplish these goals is for the two centers to work together to use the resources and the talents of the scientists associated with the US Center and the Russian Center to do collaborative research to improve the safety of Russian-designed nuclear reactors. The two centers started conducting joint research and development projects in January 1997. Since that time the following ten joint projects have been initiated: INSC databases-web server and computing center; Coupled codes-Neutronic and thermal-hydraulic; Sever accident management for Soviet-designed reactors; Transient management and advanced control; Survey of relevant nuclear safety research facilities in the Russian Federation; Computer code validation for transient analysis of VVER and RBMK reactors; Advanced structural analysis; Development of a nuclear safety research and development plan for MINITOM; Properties and applications of heavy liquid metal coolants; and Material properties measurement and assessment. Currently, there is activity in eight of these projects. Details on each of these joint projects are given.

This fault system bounds to the west the 8km deep Baringo Basin which itself lies within the axial valley of the central Kenya Rift. It mainly affects a middle Pleistocene trachytic dome (510ka), the so-called Baringo Trachyte (BT). A morphotectonic study of the 10km long BT master fault and associated downthrow geometries provides constraints on the evolution of a magma-type rift fault system from an initial stage of crack opening through to propagation. A model of radial fault growth is proposed in order to account for the longitudinal segmentation of the main fault escarpment from the median part to the tips. The small-scale half-graben geometry developed in the median high-strain zone is progressively accommodated laterally by both flexure and related narrow compensation grabens. The resulting crack swarms are well-developed at the free southern tip zone. Both the spatial distribution of rock-breaking products and their relations to the immediate hangingwall provide further evidence for this hypothesis. Well-developed screes and other gravity-driven structures (slumps) preferentially occur along the median part of the Baringo Trachyte Fault Escarpment, probably as earthquake-induced features. The hangingwall fault zone shows an asymmetrical triangular-shape with a maximum width of about half the length of the main scarp. This zone of maximum deformation and subsidence appears to be laterally controlled by two major, conjugate, transverse basement discontinuities lying with a conjugate geometry. Its internal architecture is dominated by antithetic westerly-dipping normal faults bounding discrete half-grabens, locally infilled by syn-tectonic volcaniclastics. Chronological data on hydrothermal silica filling open cracks on the BT footwall suggest that the master fault evolution occurred from 345 to 198ka, as the possible result of at least four major normal faulting earthquakes.

AN - 51210597; 2000-048831 AB - Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies (43-72 degrees C) is floored by hollow tubes composed of aragonite needle botryoids that encrust sulfide-oxidizing Aquificales bacteria. The travertine of the pond facies (30-62 degrees C) varies in composition from aragonite needle shrubs formed at higher temperatures to ridged networks of calcite and aragonite at lower temperatures. Calcite "ice sheets", calcified bubbles, and aggregates of aragonite needles ("fuzzy dumbbells") precipitate at the air-water interface and settle to pond floors. The proximal-slope facies (28-54 degrees C), which forms the margins of terracette pools, is composed of arcuate aragonite needle shrubs that create small microterracettes on the steep slope face. Finally, the distal-slope facies (28-30 degrees C) is composed of calcite spherules and calcite "feather" crystals. Despite the presence of abundant microbial mat communities and their observed role in providing substrates for mineralization, the compositions of spring-water and travertine predominantly reflect abiotic physical and chemical processes. Vigorous CO (sub 2) degassing causes a +2 unit increase in spring water pH, as well as Rayleigh-type covariations between the concentration of dissolved inorganic carbon and corresponding delta (super 13) C. Travertine delta (super 13) C and delta (super 18) O are nearly equivalent to aragonite and calcite equilibrium values calculated from spring water in the higher-temperature ( approximately 50-73 degrees C) depositional facies. Conversely, travertine precipitating in the lower-temperature (< approximately 50 degrees C) depositional facies exhibits delta (super 13) C and delta (super 18) O values that are as much as 4 per mil less than predicted equilibrium values. This isotopic shift may record microbial respiration as well as downstream transport of travertine crystals. Despite the production of H (sub 2) S and the abundance of sulfide-oxidizing microbes, preliminary delta (super 34) S data do not uniquely define the microbial metabolic pathways present in the spring system. This suggests that the high extent of CO (sub 2) degassing and large open-system solute reservoir in these thermal systems overwhelm biological controls on travertine crystal chemistry.

(super 238) Pu/ (super 239+240) Pu activity ratios are also reported for alpha spectrometric analyses undertaken on a subset of these samples. Our results indicate that the Pu in sediments on the Alaskan shelf and slope, as well as that in the deep basins (Amerasian and Eurasian) of the Arctic Ocean, has its origin in stratospheric and tropospheric fallout. Sediments from the Ob and Yenisei Rivers show isotopic Pu signatures that are distinctly different from those of northern-hemisphere stratospheric fallout and indicate the presence of weapons-grade Pu originating from nuclear fuel reprocessing wastes generated at Russian facilities within these river catchments. Consequently, sediments of the Eurasian Arctic Ocean, particularly those in the Barents and Kara Seas, probably contain a mixture of Pu from stratospheric fallout, tropospheric fallout, and fuel-reprocessing wastes of riverine origin. In particular, the (super 241) Pu/ (super 239) Pu ratios observed in these sediments are inconsistent with significant contributions of Pu to the arctic sediments studied from western European reprocessing facilities, principally Sellafield in the UK. Several other potential sources of Pu to arctic sediments can also be excluded as significant based upon the transuranic isotope ratios presented.

The U.S. Department of Energy (DOE) is the agency responsible for managing most of the depleted UF sub(6) that has been produced in the United States. The total quantity of depleted UF sub(6) that DOE has to or will have to manage is approximately 700,000 Mg. Studies have been conducted to evaluate the various alternatives for managing this material. This paper evaluates and summarizes the alternative of disposal as low-level waste (LLW). Results of the analysis indicate that UF sub(6) needs to be converted to a more stable form, such as U sub(3)O sub(8), before disposal as LLW. Estimates of the environmental impacts of disposal in a dry environment are within the currently applicable standards and regulations. Of the currently operating LLW disposal facilities, available information indicates that either of two DOE facilities - the Hanford Site or the Nevada Test Site - or a commercial facility - Envirocare of Utah - would be able to dispose of up to the entire DOE inventory of depleted UF sub(6).

For these studies, Cu super(2+) was bound specifically to a surface site on native Fe super(2+)-containing RCs from Rhodobacter sphaeroides R-26 and to the native non-heme Fe site in biochemically Fe-removed RCs. The cw and pulsed EPR results clearly indicate two spectroscopically different Cu super(2+) environments. In the dark, the RCs with Cu super(2+) bound to the surface site exhibit an axially symmetric EPR spectrum with g sub( parallel ) = 2.24, A sub( parallel ) = 160 G, g sub( perpendicular ) = 2.06, whereas the values g sub( parallel ) = 2.31, A sub( parallel ) = 143 G, and g sub( perpendicular ) = 2.07 were observed when Cu super(2+) was substituted in the Fe site. Examination of the light-induced spectral changes indicate that the surface Cu super(2+) is at least 23 Ae removed from the primary donor (P super(+)) and reduced quinone acceptor (Q sub(A) super(-)). Electron spin-echo envelope modulation (ESEEM) spectra of these Cu-RC proteins have been obtained and provide the first direct solution structural information about the ligands in the surface metal site. From these pulsed EPR experiments, modulations were observed that are consistent with multiple weakly hyperfine coupled super(14)N nuclei in close proximity to Cu super(2+), indicating that two or more histidines ligate the Cu super(2+) at the surface site. Thus, metal and EPR analyses confirm that we have developed reliable methods for stoichiometrically and specifically binding Cu super(2+) to a surface site that is distinct from the well characterized Fe site and support the view that Cu super(2+) is bound at or near the Zn site that modulates electron transfer between the quinones Q sub(A) and Q sub(B) (Q sub(A) super(-)Q sub(B) arrow right Q sub(A)Q sub(B) super(-)) and proton uptake by Q sub(B) super(-). Detailed EPR spectroscopic characterization of these Cu super(2+)-RCs will provide a means to investigate the role of local protein environments in modulating electron and proton transfer.

AN - 70910309; 10680354 AB - The application of artificial intelligence techniques for performance optimization of the fuel lean gas reburn (FLGR) system is investigated. A multilayer, feedforward artificial neural network is applied to model static nonlinear relationships between the distribution of injected natural gas into the upper region of the furnace of a coal-fired boiler and the corresponding oxides of nitrogen (NOx) emissions exiting the furnace. Based on this model, optimal distributions of injected gas are determined such that the largest NOx reduction is achieved for each value of total injected gas. This optimization is accomplished through the development of a new optimization method based on neural networks. This new optimal control algorithm, which can be used as an alternative generic tool for solving multidimensional nonlinear constrained optimization problems, is described and its results are successfully validated against an off-the-shelf tool for solving mathematical programming problems. Encouraging results obtained using plant data from one of Commonwealth Edison's coal-fired electric power plants demonstrate the feasibility of the overall approach. Preliminary results show that the use of this intelligent controller will also enable the determination of the most cost-effective operating conditions of the FLGR system by considering, along with the optimal distribution of the injected gas, the cost differential between natural gas and coal and the open-market price of NOx emission credits. Further study, however, is necessary, including the construction of a more comprehensive database, needed to develop high-fidelity process models and to add carbon monoxide (CO) emissions to the model of the gas reburn system.

These models represent typical analytically based tools that are used in human-risk and endangerment assessments at installations containing radioactive and hazardous contaminants. The objective is to demonstrate an approach for developing an adequate source term by simplifying an existing, real-world, (super 90) Sr plume at DOE's Hanford installation in Richland, WA, for use in a multimedia benchmarking exercise between MEPAS, MMSOILS, PRESTO, and RESRAD. Source characteristics and a release mechanism are developed and described; also described is a typical process and procedure that an analyst would follow in developing a source term for using this class of analytical tool in a preliminary assessment.

AN - 70803074; 10608304 AB - Concentrations of 232Th and activity ratios of 228Th to 232Th and 230Th to 232Th were determined in autopsy samples from five former employees of a thorium refinery. The ranges of 232Th activity concentrations (mBq per gram of wet tissue) were 0.17-94 in lungs, 3.9-1210 in pulmonary lymph nodes, 0.14-1.19 in bones, 0.015-0.68 in liver, 0.97-5.8 in spleen, and 0.009-0.068 in kidneys. These concentrations are 10 to 1,000 times greater than have been reported for persons not occupationally exposed to thorium. In most of the samples, the ratios of 228Th to 232Th and 230Th to 232Th activity at death of the subject were 0.2-0.4 and 0.1-0.2, respectively. 228Th to 228Ra activity ratios (+/- standard errors) of 0.86 +/- 0.11 in lungs and 1.18 +/- 0.13 in lymph nodes of one subject were obtained by calculation from ratios of 228Th to 232Th.

Efficient use of energy can also improve the air quality & reduce pollution. Therefore, municipalities should explore & encourage the development & implementation of efficient energy systems. Integrated hybrid energy systems can be designed to meet the total energy requirements of large & small communities. These systems can yield significant energy & cost savings when compared with independent systems serving individual units or when compared with the conventional practice of buying power from a utility & producing thermal energy on-site. To maximize energy & cost savings, the design engineer should look beyond the conventional when designing such systems.

Current estimates indicate that methane in hydrates exceeds fixed carbon in petroleum reserves by about a factor of three. This is a large potential source of energy, capable of lasting for centuries. In response, Japan, Korea, Norway, India and Canada are actively investigating the acquisition of methane from hydrates as an energy source. Their success could significantly restructure the global economy. While a large international focus is on methane hydrates as a source of energy, hydrates are also thought to influence ocean carbon cycling, global warming, and coastal sediment stability. Thus, methane hydrates are a significant emerging research issue. While the global distribution and quality of hydrate fields are certainly being pursued, this presentation describes more fundamental investigations of naturally formed methane hydrates. Specifically, the Naval Research Laboratory (NRL) has initiated research on the influence of hydrates on ocean floor geoacoustical and geotechnical properties. In addition, NRL and Argonne National Laboratory (ANL) have studied methane hydrates from different regions of the world ocean for variations in structure and composition. This presentation compares the methane hydrate structure, composition, and source of carbon for samples taken from the Norwegian-Greenland Sea and the Gulf of Mexico. Structural analysis is compared using x-ray diffraction. Composition is described from gas chromatography, and the carbon source is identified with carbon isotope analysis.

The conclusions drawn from these analyses are inconsistent with the current widely held "polycadinene" model for the macromolecular structure of these materials. Double bond characteristics observed by one and two dimensional NMR spectroscopy do not match those in the proposed "polycadinene" structure. Based on these observations it is suggested that the proposed "polycadinene" structure for these materials is inadequate and requires revision. Elemental and NMR data also suggest a significant contribution from functionalized monomers.

One often overlooked component of risk and impact assessments is the impact of environmental remedial actions on cultural groups proximate to contaminated sites. Cultural im-pact assessments should be undertaken because of both the im-portance of one"s culture to one"s quality of life and the role they could play in augmenting sound human health risk assess-ments. This paper presents a basis for why cultural impact as-sessments should be considered and a model for how they might be undertaken.

The evaluation assessed three different exposure scenarios: recreational use, tunnel maintenance worker, and residential use. The recreationist and maintenance worker scenarios were evaluated by using RESRAD-BUILD, a computer model for analyzing the radiological doses resulting from remediation and occupancy of structures contaminated with radioactive material. The recreationist was assumed to use the tunnels as an overnight shelter for eight hours per day for one week. The maintenance worker was assumed to spend 20 hours per year working in the tunnel. Six exposure pathways were considered for both scenarios in dose assessment. The gradual removal of surface contamination over time and ingrowth of decay products were considered in calculating the dose at different times. The maximum dose would occur immediately after the release and was estimated to be 1.9 mrem/yr for the recreationist and 0.9 mrem/yr for the maintenance worker. The residential scenario was evaluated by using the probabilistic RESRAD code. It was assumed that total activity from the tunnels would be brought into the near-surface layer by future human activities. Eight exposure pathways were considered. The maximum yearly dose for this very unlikely scenario would occur immediately after the release and was less than 4 mrem/yr for the maximally exposed individual. The assessment demonstrates that both codes are suitable for nuclear facility decontamination and decommissioning sites, where buildings and structures with residual radioactivity must be evaluated to facilitate property transfer or release.

Even though these fungal mediated feedbacks and linkages involve lower-organizational level processes (e.g. photo-assimilate partitioning, interfacial assimilate uptake and transport mechanisms, intraradical versus extraradical fungal growth), they influence higher-organizational scales that affect community and ecosystem behavior (e.g. whole-plant photosynthesis, biodiversity, nutrient and carbon cycling, soil structure). Hence, incorporating AM fungi into research directed at understanding many of the diverse environmental issues confronting society will require knowledge of how these fungi respond to or initiate changes in vegetation dynamics, soil fertility or both. Within the last few years, the rapid advancement in the development of analytical tools has increased the resolution by which we are able to quantify the mycorrhizal symbiosis. It is important that these tools are applied within a conceptual framework that is temporally and spatially relevant to fungus and host. Unfortunately, many of the studies being conducted on the mycorrhizal symbiosis at lower organizational scales are concerned with questions directed solely at understanding fungus or host without awareness of what the plant physiologist or ecologist needs for integrating the mycorrhizal association into larger organizational scales or process levels. We show by using the flow of C from plant-to-fungus-to-soil, that through thoughtful integration, we have the ability to bridge different organizational scales. Thus, an essential need of mycorrhizal research is not only to better integrate the various disciplines of mycorrhizal research, but also to identify those relevant links and scales needing further investigation for understanding the larger-organizational level responses.

In particular, a major issue associated with a contaminated structure is whether there is a realistic potential for future use of the structure. This issue should be addressed early in a planning process. The resolution of this issue significantly affects other major issues associated with management of a contaminated structure such as: (1) What are the expected costs associated with management of the structure? (2) What regulatory requirements are applicable? (3) What characterization is needed? (4) What risk assessment is necessary? and (5) What remediation decisions must be made? This article considers all of these issues.
