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.
