TY - JOUR T1 - Monitoring aquifer depletion from space; case studies from the Saharan and Arabian Aquifers AN - 1696876064; 2015-068339 AB - Access to potable fresh water resources is a human right and a basic requirement for economic development in any society. In arid and semi-arid areas, the characterization and understanding of the geologic and hydrologic settings of, and the controlling factors affecting, these resources is gaining increasing importance due to the challenges posed by increasing population. In these areas, there is immense natural fossil fresh water resources stored in large extensive aquifers, the transboundary aquifers. Yet, natural phenomena (e.g., rainfall patterns and climate change) together with human-related factors (e.g., population growth, unsustainable over-exploitation, and pollution) are threatening the sustainability of these resources. In this study, we are developing and applying an integrated cost-effective approach to investigate the nature (i.e., natural and anthropogenic) and the controlling factors affecting the hydrologic settings of the Saharan (i.e., Nubian Sandstone Aquifer System [NSAS], Northwest Sahara Aquifer System [NWSA]) and Arabian (i.e., Arabian Peninsula Aquifer System [APAS]) aquifer systems. Analysis of the Gravity Recovery and Climate Experiment (GRACE)-derived Terrestrial Water Storage (TWS) inter-annual trends over the NSAS and the APAS revealed two areas of significant TWS depletions; the first correlated with the Dakhla Aquifer System (DAS) in the NSAS and second with the Saq Aquifer System (SAS) in the APAS. Annual depletion rates were estimated at 1.3 + or - 0.66 X 10 (super 9) m (super 3) /yr and 6.95 + or - 0.68 X 10 (super 9) m (super 3) /yr for DAS and SAS, respectively. Findings include (1) excessive groundwater extraction, not climatic changes, is responsible for the observed TWS depletions; (2) the DAS could be consumed in 350 years if extraction rates continue to double every 50 years and the APAS available reserves could be consumed within 60-140 years at present extraction (7.08 X 10 (super 9) m (super 3) /yr) and depletion rates; and (3) observed depletions over DAS and SAS and their absence across the remaining segments of the NSAS and the APAS suggest the aquifers are at near-steady conditions except for the DAS and SAS that are witnessing unsteady transient conditions. Implications for applying the methodologies advocated for assessment and optimum management of a large suite of fossil aquifers worldwide are clear.

Understanding how this stratification was established is at the center of many interrogations in Earth sciences, such as why is there Fe3+ in Earth, was there a secular change in the redox state of the mantle, how does recycling affect redox conditions in the Earth? Iron isotopic variations have been detected in igneous rocks but interpretation of those results is uncertain because the database of equilibrium fractionation factors between phases is incomplete or even entirely missing for some phases. This can be addressed using a synchrotron by measuring the mean force constant of iron bonds, which is proportional to the third moment of the spectra measured by nuclear resonant inelastic x-ray scaterring. Those force constant measurements help us understand why oceanic crust has heavy iron isotopic composition relative to chondrites, they can explain the large isotopic fractionation measured in silicic melts, and they can help us test the idea that core formation fractionated iron isotopes. New NRIXS measurements of synthetic phases enriched in 57Fe that shed new light on these questions will be presented.

The P-T conditions of the cores of Mars, Mercury, Earth's moon, Io and Ganymede are thought to lie in the stability field of fcc-structured Fe alloyed with approximately 10 wt% Ni (e.g., Fei et al. 2005). Geomagnetic surveys suggest these terrestrial bodies either have or once had a magnetic dynamo (e.g., Margot et al. 2007), which likely requires the presence of a liquid metallic core surrounding a solid inner core. Therefore, an accurate determination of the melting temperature of fcc-structured Fe-Ni at high pressure will provide constraints on the thermal structure of these small terrestrial bodies, and in turn, may provide insight to their magnetic dynamo and interior evolution history. We have developed a new metric for detecting the solid-liquid phase boundary of Fe-bearing materials at high-pressures using synchrotron Mossbauer spectroscopy (SMS). Focused synchrotron radiation with 1 meV bandwidth passes through a laser-heated Fe-bearing sample inside a diamond-anvil cell. The characteristic SMS time signal vanishes when melting occurs. This process is described by the Lamb-Mossbauer factor, a quantity that is directly related to the mean-square displacement of the Fe atoms. Therefore, we measure the atomic dynamics in the material, in contrast to a static diffraction measurement. The SMS technique provides a new and independent means of melting point determination for materials under high-pressure, as well as access to vibrational properties of the solid near its melting point (Jackson et al. 2013). Accurate melting temperatures of the sample are also necessary factors in constructing reliable melting curves. However, most conventional temperature measurement methods in laser-heated diamond-anvil cell studies are often too slow ( approximately 0.3 Hz) to capture the sample's transient temperature fluctuations, which can be significant for materials near their melting points. To accurately capture this effect and reduce uncertainties in melting temperatures, we have developed a Fast Temperature Readout (FasTeR) spectrometer in-line with nuclear resonance scattering measurements under extreme conditions at Sector 3-ID-B of the Advanced Photon Source. Dedicated to determining the sample's temperature near its melting point, FasTeR features a fast readout rate ( approximately 100 Hz), high sensitivity, large dynamic range and well-constrained focus. FasTeR may also be ideal for a variety of short time-scale measurements conducted at high-temperatures. FasTeR has been successfully combined with SMS measurements on compressed fcc-structured Fe alloyed with 10 wt% Ni to determine the melting curve by monitoring the dynamics of the atoms.

Nearly all of the Earth is composed of polymineral aggregates, including the lower mantle, which is of critical importance for understanding the geodynamic evolution of the planet. Geodynamic models predict large strains due to convection in the mantle, and polycrystal plasticity simulations suggest strong crystallographic preferred orientation (CPO). However, these models ignore interaction among phases, which is important for the lower mantle, estimated to be composed of approximately 25% soft magnesiowustite (Mg,Fe)O and approximately 70% harder Mg-perovskite (MgSiO (sub 3) ). Grains of the soft phase may become interconnected and act as a lubricant between grains of the harder phase, or the soft phase may not be interconnected, causing deformation to be absorbed by the harder phase. To study the effect of a second phase on CPO, we performed deformation experiments in the deformation-DIA (D-DIA) at the Advanced Photon Source (APS) while collecting X-ray diffraction patterns in situ. Since D-DIA cannot reach pressures of the lower mantle, we chose analog minerals halite (NaCl) and neighborite (NaMgF (sub 3) ) with the same structures and relative strengths as the original mantle minerals. Information on grain structure and distribution before and after deformation was collected using X-ray microtomography, both at the APS and the Advanced Light Source (ALS). Results from D-DIA experiments show that when present in as little as 25%, the soft phase absorbs much of the deformation, greatly reducing CPO of the harder phase. Conversely, CPO in NaCl is highest for the sample with highest NaCl content. This suggests that crystallographic orientation develops and evolves best in rocks largely composed of one mineral phase, and the addition of a second phase greatly hinders CPO, even at high strain. In addition, microtomography data shows that soft NaCl surrounds the harder grains of NaMgF (sub 3) . These findings are very encouraging, and we continue our study of two-phase deformation texture and microstructure with fast Fourier transform (FFT) modeling which takes into account interactions among grains.

However, only recently the method became practicable for real case investigations due to significant analytical improvements [1]. In this study radioactive noble gas isotopes ( (super 81) Kr, (super 85) Kr and (super 39) Ar) were applied for the characterisation of fracture waters in the deep gold mines of the Witwatersrand Basin, South Africa [2]. Those waters catalyzed interest because of deep microbial communities that persists to depths of over 3 km [3]. The key objective of the present study is to further constrain the origin of the fluids, to determine the timing of deep subsurface life and to test the (super 81) Kr method in all kinds of environments. In contrast to expectations [4] we discovered that underground production of (super 81) Kr is a significant process in the rocks of the Withwatersrand and Ventersdorp Supergroups. All measured (super 81) Kr activities from fracture water were significantly higher than in atmospheric equilibrium. This is most likely related to elevated U/Th concentrations in the rock strata. Radiometric decay dating is complicated in such cases. [1]. W. Jiang et al., Geochim. Cosmochim. Acta 91, 1 (2012). [2].T. C. Onstott et al., Geomicrobiology J. 26, 269 (2009). [3].G.

(1998) reported that the post-spinel transition occurs at 21.3 GPa and 1850 K using Anderson et al. (1989) Au scale in Mg (sub 2) SiO (sub 4) , while a later laser-heated diamond-anvil cell (LHDAC) study (Shim et al., 2001) reported 23.8 GPa using Holmes et al. (1989) Pt scale at the same temperature. The 2.6-GPa difference has been attributed to the accuracy of the pressure scales. However, high-temperature equations of state (EOS) of Au and Pt have been compared only at a limited pressure-temperature range in multi-anvil press (Fei et al., 2004). We have compared the thermal EOS of Au, Pt, and MgO at 20-30 GPa and 1700-2100 K in LHDAC combined with synchrotron X-ray diffraction at the GSECARS and HPCAT sectors of APS through two different approaches: (1) determination of the post-spinel boundary in a MgO-Al (sub 2) O (sub 3) -SiO (sub 2) pyrolitic composition using the Au and Pt scales, and (2) unit-cell volume measurements on separate MgO+Au and MgO+Pt mixtures. In order to prevent alloying between Pt and Au, we did not mix them, but prepared separate samples and loaded in separate DACs. All the samples were loaded with an argon medium. Diffraction pattern analysis shows that deviatoric stress should be less than 1 GPa at high temperature. Spectroradiometry data show that temperature gradients should be less than 100 K. We found that the post-spinel boundary occurs at 23.4+ or -0.2 GPa (at 1850 K) if Holmes et al. (1989) Pt scale is used, while at 24.3+ or -0.2 GPa for Fei et al. (2007) Pt scale. In separate measurements, the transition occurs at 25.8+ or -0.2 GPa for Anderson et al. (1989) Au scale and 27.6+ or -0.2 GPa for Fei et al. (2007) Au scale, indicating 3.3+ or -0.3 GPa discrepancy between Fei et al. (2007) Pt and Au scales, thermal parts of which are mainly constrained by intercalibration data at 21-24 GPa and 1400-2200 K in multi-anvil press (Fei et al., 2004). Our data on MgO+Pt mixtures show that pressures from Fei et al. (2007) Pt scale is 1.9+ or -0.6 GPa lower than those of Speziale et al. (2000) MgO scale at 20-30 GPa and 1700-2100 K. Our MgO+Au mixture data indicate that Fei et al. (2007) Au scale is 0.9+ or -0.3 GPa higher than the MgO scale in the pressure-temperature range, suggesting a pressure difference of 2.8+ or -0.6 GPa between Fei et al. (2007) Pt and Au scales at the pressure-temperature conditions expected for the post-spinel transition, consistent with what we found for the post-spinel phase boundary determination. Anderson et al. (1989) Au scale yields a post-spinel phase transition pressure of 21.3 GPa for multi-anvil data (Irifune et al. 1998) and 25.8+ or -0.2 GPa for our LHDAC data. While the comparison should be made with caution because of kinetic effects and compositional differences, the discrepancy may indicate that much of the 3-GPa difference identified from our two different sets of experiments may result from technical differences between multi-anvil press and LHDAC, including pressure effects on thermocouple calibration and emissivity of the laser couplers, as well as inaccuracy of existing pressure scales. The 3-GPa discrepancy correspond to a depth uncertainty of 85 km near 660 km depth, placing severe limitations in our ability to apply laboratory results to the interpretation of seismic studies.

A reliable estimate of the degassing flux is critical to the use of (super 4) He as a dating tool in groundwater studies. The degassing flux is also important for understanding fluid and heat transport in the mantle and the rust. An independent tracer of groundwater age is required in order to deconvolute the two signals of the external, degassing flux and in situ production. Estimates of degassing flux mostly have relied upon shorter-lived radionuclides such as (super 14) C and tritium and the resulting flux estimates have a significant variability (Torgersen, 2010). In the Guarani Aquifer in Brazil, an effective crustal (super 4) He degassing flux into the aquifer was estimated from (super 81) Kr ages ranging from about 70 Ka to 570 Ka. We then used the model framework of Toregesen and Ivey (1985), modified to include a diffusive reduction of originally uniform crustal helium flux from basement rocks through a thick sedimentary layer beneath the aquifer, to calculate a distribution of radiogenic (super 4) He within the aquifer. With this framework, we obtain (super 4) He ages that are consistent with ages based on (super 81) Kr and (super 14) C, and with a crustal degassing flux equivalent to that estimated from U and Th contents in the crust. The model framework for the Guarani Aquifer is also applied to data from other deep aquifers in Africa and Australia and our results suggest that the continental flux of (super 4) He may be uniform, at least in stable continental areas. Additionally, a reliable estimate of the (super 4) He degassing flux also helps to constrain the surficial discharge of deep groundwater.

During our nano-mineralogy investigation of the Tissint meteorite with a combined analytical scanning electron microscope and synchrotron diffraction approach, two new shock-induced minerals have been discovered; these provide new insights into understanding shock conditions and impact processes on Mars. Ahrensite (IMA 2013-028), the Fe-analogue (gamma -Fe (sub 2) SiO (sub 4) ) of ringwoodite, is a new high-pressure mineral identified in Tissint. Both ahrensite and ringwoodite occur in Tissint as fine-grained polycrystalline aggregates in the rims of olivines around some shock-melt pockets. The morphology and texture of these silicate-spinels suggest formation by a solid-state transformation from Fe-rich olivine. Associated with the ahrensite and ringwoodite, inside melt pockets, often resides a thin layer of vitrified silicate-perovskite and magnesio-wustite or wustite. Such transitions represent a unique pressure and temperature gradient. Tissintite (IMA 2013-027), (Ca,Na,)AlSi (sub 2) O (sub 6) with the C2/c clinopyroxene structure, is a new jadeite-like mineral in Tissint. It appears as fine-grained aggregates within plagioclase glass, inside many shock-melt pockets. Both ahrensite and tissintite are high-pressure minerals formed by shock during the impact event(s) on Mars that excavated and ejected the rock off Mars. We will discuss the path of structure analysis for both new-mineral cases. Such novel methodology be utilized for many cases of mineralogical phase identification or structure analysis; this demonstrates how nano-mineralogy can be addressed and how it may play a unique role in meteorite and Mars rock research, in general.

However a fundamental relationship between mineral lattice preferred orientation (LPO or fabrics), kerogen, and elastic properties of shale remains questionable. Here we present different synchrotron X-ray techniques to capture microstructural transformations in Kimmeridge Shale upon temperature-induced anhydrous maturation. At room condition, the sample is mainly composed of clays 72 vol.%, quartz (15 vol.%), pyrite (11 vol.%), and a small amount of pyrite (2 vol.%). Illite-group is the dominating clay with 50 vol.% present. Illite-mica (30 vol.%) shows the highest degree of LPO (3.33 m.r.d.), which is consistent with previous studies (Wenk et al 2008, Voltolini et al. 2009, Kanitpanyacharoen et al. 2011). However the illite-smectite group exhibits relatively weaker degree of LPO due to the disordered nature of the structure. Chlorite shows the least degree of LPO due to its total clay content, which is only 2 vol.%. Upon heating to 300 degrees C, the phase proportions did not change much and the degrees of all clay minerals fabrics remain fairly consistent. The high-resolution 3D imaging technique allows us to record different stages of kerogen transformation, particularly a significant gas bubble formation at 400 degrees C. Upon heating up to 500 degrees C, kerogen shrinkage (17 vol.%) and clay matrix expansion continued and appeared more pronounced after 10 hours of heating. The consistent results from both experiments confirm that no significant change of mineral fabrics and microstructural features below 300 degrees C observed. These findings further infer that the evolution of clay fabrics and kerogen maturation may affect elastic anisotropy consistently at the temperature below 300 degrees C. The reduction of kerogen greatly influences elastic anisotropy properties and the identification of the promising source in the hydrocarbon reservoir.

In addition to deep ice cores, old ice can also be found at ice margin sites and blue ice areas (BIAs) where it is exposed due to local ice dynamics and ablation. BIAs have great potential for paleoclimate studies, as large quantities of old ice are available at the surface where it can be sampled with relative ease. Determining the age of the ablating ice is the main difficulty in using BIAs for climate reconstructions. There is significant scientific interest in obtaining glacial ice dating beyond 800 ka, as such an archive would extend the ice core record further back in time; such old ice can potentially be found in Antarctic BIAs such as the Allan Hills site, providing a strong impetus to developing reliable (absolute) dating tools for glacial ice. (super 81) Kr is naturally produced in the upper atmosphere by cosmic ray interactions with the stable isotopes of Kr. The long half-life (229 ka) of (super 81) Kr allows for radiometric dating in the 50 ka - 1.5 Ma age range, well past the reach of radiocarbon dating. Recent technological advances in Atom Trace Trap Analysis (ATTA) have reduced sample requirements to 40-80 kg of ice, which can realistically be obtained from BIAs and ice margins. We present the first successful (super 81) Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four approximately 350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using ATTA. The (super 81) Kr radiometric ages agree with independent age estimates obtained from stratigraphic dating techniques with a root mean square offset of 6.5 ka. Our experimental methods and sampling strategy are validated by 1) (super 85) Kr and (super 39) Ar analyses that show the samples to be free of modern air contamination, and 2) air content measurements that show the ice did not experience gas loss. We estimate the error in the (super 81) Kr ages due to past geomagnetic variability to be below 3 ka. We show that ice from the Eemian interglacial period (130-115 ka BP) can be found in abundance near the surface of Taylor Glacier. Our study paves the way for reliable radiometric dating of ancient ice in blue ice areas and margin sites, greatly enhancing their scientific value as archives of old ice and meteorites. As sample requirements continue to decrease, (super 81) Kr dating of ice cores is a future possibility.

It is constructed within halite beds of the Permian-age Salado Formation. The Culebra Dolomite, confined within Rustler Formation evaporites, is a potential pathway for radionuclide transport from the repository to the accessible environment in the human-disturbed repository scenario. Although extensive subsurface characterization and numerical flow modeling of groundwater has been done in the vicinity of the WIPP, few studies have used natural isotopic tracers to validate the flow models at this site. We performed measurements of the cosmogenic isotopic tracer (super 81) Kr (half-life 229,000 yr) in two Culebra monitoring wells near the WIPP site, and compared (super 81) Kr model ages with the results of an ensemble of flow models. The (super 81) Kr model ages were approximately 130,000 and approximately 330,000 yr for high-transmissivity and low-transmissivity portions of the aquifer, respectively. These model ages are in broad agreement with flow model results, when taking into account diffusive exchange of Kr between the aquifer and the stagnant zones of the confining formations.

The instrument is based on Atom Trap Trace Analysis (ATTA), a novel laser based atom counting technique that allows detection of long lived noble gas radioisotopes (Kr-81, Kr-85 and Ar-39) with extremely low abundance (1E-16 to 1E-10). At the center of the instrument is a magneto-optical trap (MOT), which traps and counts only the atoms of the desired isotope. This unique feature makes ATTA free of interference from any other isotopes or molecular species. For Kr-81 dating in the age range of 150 - 1,500 kyr, the required sample size is 5 - 10 micro-L STP of krypton gas, which can be extracted from approximately 100 - 200 kg of water or 40 - 80 kg of ice. Several recent developments in our lab may lead to further improvements to the current ATTA-3 apparatus: 1) The isotopic abundance ratio between the unknown, rare isotope (either Kr-81 or Kr-85) and the stable, abundant isotope (Kr-83) is measured. Here the stable isotope serves as a control isotope. A new method has been developed that allows more accurate measurements of the control isotope Kr-83. Combined with the ability to measure the rare Kr-81 and Kr-85 isotopes, this scheme allows ATTA-3 to directly determine (super 81) Kr/Kr and (super 85) Kr/Kr ratios without other supplemental measurements, to reduce the overall uncertainties of the measured isotope ratios, and also to improve the long term stability of the system. 2) The current capacity of the ATTA-3 instrument is about 120 samples per year. The throughput is mainly limited by the so called "memory effect", which is caused by the residual samples trapped in the system after each measurement. These residual samples are gradually released in subsequent measurements, causing cross-sample contaminations. In order to mitigate this problem, we wash the system with a xenon discharge for about 36 hours between measurements. This practice limits the overall sample processing speed. Preliminary investigations of the memory effect indicate that it can be reduced and the wash time between measurements shortened. This will increase the number of samples that the ATTA-3 instrument can handle annually in the future. This work is supported by DOE, Office of Nuclear Physics, under contract DE-AC02-06CH11357.

Recent advances in detector technology allow collecting these images at unprecedented frame rates. For a high x-ray flux density synchrotron facility like the Advanced Photon Source (APS), the detector exposure time ranges from hundreds of milliseconds to hundreds of picoseconds, making possible to acquire a full 3D micrometer-resolution dataset in less than one second. The micron resolution limitation of parallel x-ray beam projection systems can be overcame by Transmission X-ray Microscopes (TXM) where part of the image magnification is done in x-ray regime using x-ray optics like capillary condensers and Fresnel zone plates. These systems, when installed on a synchrotron x-ray source, can generate 2D images with up to 20 nm resolution with second exposure time and collect a full 3D nano-resolution dataset in few minutes. mu -XCT and TXM systems available at the x-ray imaging beamlines of the APS are routinely used in material science and geoscience applications where high-resolution and fast 3D imaging are instrumental in extracting in situ four-dimensional dynamic information. In this presentation we describe the computational challenges associated with mu -XCT and TXM systems and present the framework and infrastructure developed at the APS to allow for routine multi-scale data integration between the two systems.

Using a diamond anvil cell with high-energy synchrotron X-ray, the total scattering of metallic glass Yb-Mg-Zn was studied at pressure up to 30GPa in a hydrostatic isopropanol pressure-medium. The local structure was investigated through direct Fourier transformation of the structure factor [S(Q)], pair distribution function (PDF) [G(r)] with background correction. Polyamorphic phase transition is achieved because smaller atoms are extruded into the clearance of the larger rare earth atoms and 4f electrons delocalized. Phase transition from a low-density state to a high-density state occurs, smaller atoms can be extruded is one of two reasons for the high compressibility of rare earth BMG. The second reason is the delocalization of 4f electrons, which can induce the volume collapse of rare earth atoms.

Local structures in melts trend to show short range ordering within a few tenths of a nanometer, which are often considered to be correlated with the atomic arrangements of their solid counterparts. For non-crystalline samples, such as amorphous materials and melts, Due to their lack of periodicity, diffraction patterns from amorphous and liquid phases are very broad; therefore, it is challenging to obtain density information under high-pressure conditions. On the other hand, x-ray microtomography can provide density and geometry information on samples regardless of their crystallinity. Synchrotron x-ray microtomography enables us to carry out in situ density measurements on liquids at high pressures. Thus, we can address whether there are liquid-liquid phase transitions of gallium and better understand the physical processes of phase transitions.

Single-crystal X-ray diffraction measurements confirmed the stability of Fe (sub 7) C (sub 3) up to core pressures, and provide support for the scenario of carbon-rich inner core on the basis of density match [Chen et al., 2012]. To further test the hypothesis of Fe (sub 7) C (sub 3) -dominant inner core, we have performed nuclear resonant inelastic X-ray scattering (NRIXS) measurements of Fe (sub 7) C (sub 3) up to 150 GPa at 300 K, in order to determine the shear-wave (V (sub S) ) and compressional-wave (V (sub P) ) velocities for comparison with seismic models. Our results show that the high-spin to low-spin magnetic transition in Fe (sub 7) C (sub 3) near 50 GPa, as manifested by the change of compression behavior and our recent X-ray Emission Spectroscopy measurements, also significantly affects the pressure dependence of the V (sub S) and V (sub P) . Extrapolating the measured sound velocities to the relevant core pressures and temperatures, we found that the non-magnetic Fe (sub 7) C (sub 3) could reproduce the V (sub S) of the inner core, making it potentially the largest reservoir of carbon in Earth.

Therefore, it is important to understand the physical properties of Al,Fe-rich mantle silicate perovskite. We have synthesized Fe,Al-rich mantle silicate perovskites from two different starting materials [Mg (sub 2) FeAl (sub 2) Si (sub 3) O (sub 12) (Alm33) and Mg (sub 2.5) Fe (sub 0.5) Al (sub 2) Si (sub 3) O (sub 12) (Alm17)] and conducted in-situ synchrotron X-ray diffraction (GSECARS and HPCAT) and Mossbauer spectroscopy (Sector 3) in the laser heated diamond-anvil cell at Advanced Photon Source. The garnet starting materials were synthesized in the multi-anvil press at Arizona State University. The starting materials were mixed with 10 wt% Au powder (internal pressure standard) and loaded with an Ar or Ne pressure medium in the diamond-anvil cell for X-ray diffraction measurements. Pure starting materials are loaded in the diamond-anvil cell with an Ne or KCl pressure medium for synchrotron Mossbauer measurements. In synchrotron Mossbauer spectroscopy, we obtained pressure from the unit-cell volumes of pressure media combined with their equations of state. During the laser heating of the Alm33 starting material at approximately 66 GPa and approximately 2300 K, perovskite was synthesized with a small amount of stishovite. For the same starting material, pure perovskite was synthesized at 90 GPa and approximately 2300 K. For the Alm17 starting material, perovskite was synthesized with a small amount of stishovite at 65-92 GPa and approximately 2200K. Between 60 and 90 GPa, the unit-cell volumes of the Alm33 and Alm17 perovskites are only slightly higher (0.3-0.6%) than that of Mg-end member perovskite and are comparable to that of (Mg (sub 0.85) Fe (sub 0.15) )SiO (sub 3) perovskite, indicating higher density of the Al,Fe-rich perovskite in subducting oceanic crust than surrounding mantle. Both Al,Fe-rich perovskites show a steep increase in unit-cell volume during decompression between 60 and 40 GPa, suggesting either spin transition or metastability at the pressure range. We successfully quenched both Al,Fe-rich perovskites and measured the unit-cell volumes at 1 bar: 166.3+ or -0.1 Aa (super 3) for Alm17 perovskite, and 165.0+ or -0.2 Aa (super 3) for Alm33 perovskite. Our direct measurements indicate that the combined effects of Fe and Al on the unit-cell volume is much greater at lower pressures ( approximately 2%) than those observed at higher pressure (0.3-0.6%). The preliminary spectral fitting of synchrotron Mossbauer data indicates that 50 approximately 80% of iron is Fe (super 3+) in both Al,Fe-rich pervoskites, suggesting that similar degree of charge disproportionation reaction occurs in Al-rich mantle silicate perovskite. This result is in disagreement with a recent thermodynamic prediction by Nakajima et al. (2012, JGR) that Fe (super 3+) concentration may be very low (near zero) in Al-rich perovskite.

Using a laser-heated diamond anvil cell, our experiments at pressures of 95-105 GPa and temperatures of 2200 approximately 2400 K show that such perovskite is unstable; it loses its Fe and disproportionates into a nearly Fe-free MgSiO3 pv and an Fe-rich (Mg,Fe)SiO3 phase with a previously unknown hexagonal structure, causing a small volume reduction. Using the newly developed high-pressure multigrain crystallography technique, we have identified 154 individual crystallites belonging to the hexagonal phase in one experiment, each has a unique orientation matrix with as many as 27 diffraction spots that gives identical unit-cell parameters, while 130 individual crystallites of the coexisting pv phase were indexed to the known Pbnm space group. This new mineral physics observation leads to a fresh view on geophysical, geochemical and geodynamic paradigms for the lower mantle below 2000 kilometers depth.

High pressure-temperature and Si alloying effects on sound velocities of Fe are of great importance to establish satisfactorily geophysical and geochemical models of the core. To date, the nature of the stable phase of iron in the Earth's inner core is still on debate. Several recent theoretical and experimental studies have suggested that Fe in the core would be stabilized in the body-centered cubic (bcc) phase with respect to the hexagonal close-packed (hcp) phase. These studies have further concluded that the addition of Si in the core can also enhance the stability of the bcc-Fe. Therefore, it is also of critical importance to understand the elastic behavior of bcc Fe-Si alloys at high pressure and temperature. However, there are only a few studies on sound velocities of bcc-Fe either at high pressure or at high temperature. Here we have investigated the compressional wave velocity (VP) and density (rho ) profiles of bcc-Fe and Fe0.85Si0.15 alloy (8 wt% Si) using high-energy resolution inelastic X-ray scattering (HERIX) and synchrotron X-ray diffraction spectroscopies in an externally-heated diamond anvil cell (EHDAC) at high P-T conditions. Our results show a strong VP reduction at elevated temperatures even at a constant density. Compared with the literature velocity results for bcc and hcp Fe-Si alloys, the bcc-Fe and Fe-Si alloy exhibit higher VP than their hcp phase counterparts at the bcc-hcp transition pressures. If the bcc phase is present in Earth's inner core, our results here indicate that a few wt% of Si as the major light element is needed to compensate the density-velocity deficit of the inner core. Due to the extremely high elastic anisotropy of bcc Fe-Si alloy, a certain portion of the bcc Fe-Si alloy with the lattice-preferred orientation can produce VP and VS anisotropies to potentially account for the observed seismic anisotropy in the inner core.

Kim et al. reported that IL growth was reduced as Si reduced Al diffusion to U-Mo [1],[2]. As the fuel loading increases, however, the total amount of Si is reduced in the fuel meat. Furthermore, the effective Si amount available to nearby U-Mo particles decreases locally where the fuel particle population is high. All of the above reduce the effect of Si addition in suppressing IL growth.

The RPL multiresolution hierarchy is being designed to ultimately span the full range of length and time scales present in relevant reactor design and safety analyses scenarios. Accomplishing this aggressive goal requires that RPL components exhibit good parallel scalability from desktop to petaflop computing platforms.

2013-093472 AB - MgSiO (sub 3) akimotoite is stable relative to majorite-garnet under low-temperature geotherms within steeply or rapidly subducting slabs. Two compositions of Mg-akimotoite were synthesized under similar conditions: Z674 (containing about 550 ppm wt H (sub 2) O) was synthesized at 22 GPa and 1,500 degrees C and SH1101 (nominally anhydrous) was synthesized at 22 GPa and 1,250 degrees C. Crystal structures of both samples differ significantly from previous studies to give slightly smaller Si sites and larger Mg sites. The bulk thermal expansion coefficients of Z674 are (153-839 K) of a (sub 1) = 20(3) X 10 (super -9) K (super -2) and a (sub 0) = 17(2) X 10 (super -6) K (super -1) , with an average of alpha (sub 0) = 27.1(6) X 10 (super -6) K (super -1) . Compressibility at ambient temperature of Z674 was measured up to 34.6 GPa at Sector 13 (GSECARS) at Advanced Photon Source Argonne National Laboratory. The second-order Birch-Murnaghan equation of state (BM2 EoS) fitting yields: V (sub 0) = 263.7(2) Aa (super 3) , K (sub T0) = 217(3) GPa (K' fixed at 4). The anisotropies of axial thermal expansivities and compressibilities are similar: alpha (sub a) = 8.2(3) and alpha (sub c) = 10.68(9) (10 (super -6) K (super -1) ); beta (sub a) = 11.4(3) and beta (sub c) = 15.9(3) (10 (super -4) GPa). Hydration increases both the bulk thermal expansivity and compressibility, but decreases the anisotropy of structural expansion and compression. Complementary Raman and Fourier transform infrared (FTIR) spectroscopy shows multiple structural hydration sites. Low-temperature and high-pressure FTIR spectroscopy (15-300 K and 0-28 GPa) confirms that the multiple sites are structurally unique, with zero-pressure intrinsic anharmonic mode parameters between -1.02 X 10 (super -5) and +1.7 X 10 (super -5) K (super -1) , indicating both weak hydrogen bonds (O-H...O) and strong OH bonding due to long O...O distances.

AN - 1443415984; 24067076 AB - A significant issue related to Palladium (Pd) based catalysts is that sulfur-containing species, such as alkanethiols, can form a PdSx underlayer on nanoparticle surface and subsequently poison the catalysts. Understanding the exact reaction pathway, the degree of sulfidation, the chemical stoichiometry, and the temperature dependence of this process is critically important. Combining energy-filtered transmission electron microscopy (EFTEM), X-ray diffraction (XRD), and X-ray absorption spectroscopy experiments at the S K-, Pd K-, and L2,3-edges, we show the kinetic pathway of Pd nanoparticle sulfidation process with the addition of excess amount of octadecanethiol at different temperatures, up to 250 °C. We demonstrate that the initial polycrystalline Pd-oleylamine nanoparticles gradually become amorphous PdSx nanoparticles, with the sulfur atomic concentration eventually saturating at Pd/S = 66:34 at 200 °C. This final chemical stoichiometry of the sulfurized nanoparticles closely matches that of the crystalline P16S7 phase (30.4% S), albeit being structurally amorphous. Sulfur diffusion into the nanoparticle depends strongly on the temperature. At 90 °C, sulfidation remains limited at the surface of nanoparticles even with extended heating time; whereas at higher temperatures beyond 125 °C, sulfidation occurs rapidly in the interior of the particles, far beyond what can be described as a core-shell model. This indicates sulfur diffusion from the surface to the interior of the particle is subject to a diffusion barrier and likely first go through the grain boundaries of the nanoparticle.

It is of interest in bioremediation efforts due to its dechlorination and metal-reducing capabilities. To gain an understanding on A. dehalogenans' abilities to adapt to diverse environments we analyzed its signal transduction proteins. The A. dehalogenans genome codes for a large number of sensor histidine kinases (HK) and methyl-accepting chemotaxis proteins (MCP); among these 23 HK and 11 MCP proteins have a sensor domain in the periplasm. These proteins most likely contribute to adaptation to the organism's surroundings. We predicted their three-dimensional folds and determined the structures of two of the periplasmic sensor domains by X-ray diffraction. Most of the domains are predicted to have either PAS-like or helical bundle structures, with two predicted to have solute-binding protein fold, and another predicted to have a 6-phosphogluconolactonase like fold. Atomic structures of two sensor domains confirmed the respective fold predictions. The Adeh_2942 sensor (HK) was found to have a helical bundle structure, and the Adeh_3718 sensor (MCP) has a PAS-like structure. Interestingly, the Adeh_3718 sensor has an acetate moiety bound in a binding site typical for PAS-like domains. Future work is needed to determine whether Adeh_3718 is involved in acetate sensing by A. dehalogenans. The Anaeromyxobacter dehalogenans CP-C genome codes for a large number of sensor histidine kinases (HK) and methyl accepting chemotaxis proteins (MCP); among these 23 HK and 11 MCP proteins have a sensor domain in the periplasm. These proteins most likely contribute to adaptation to the organism's surroundings. We predicted their three-dimensional folds and determined the structures of two of the periplasmic sensor domains by X-ray diffraction.

To better understand the non-trivial spatio-temporal correlations emerging in the course of collective swimming in suspensions of motile bacteria, a simple model is employed: a bacterium is represented as a force dipole with size, through the use of a short-range repelling potential, and shape. The model emphasizes two fundamental mechanisms: dipolar hydrodynamic interactions and short-range bacterial collisions. Using direct particle simulations validated by a dedicated experiment, we show that changing the swimming speed or concentration alters the time scale of sustained collective motion, consistent with experiment. Also, the correlation length in the collective state is almost constant as concentration and swimming speed change even though increasing each greatly increases the input of energy to the system. We demonstrate that the particle shape is critical for the onset of collective effects. In addition, new experimental results are presented illustrating the onset of collective motion with an ultrasound technique. This work exemplifies the delicate balance between various physical mechanisms governing collective motion in bacterial suspensions and provides important insights into its mesoscopic nature.

Currently, analysis of XRF images is often done using manually defined regions of interest (ROIs). However, since advances in synchrotron instrumentation have enabled the collection of very large data sets encompassing hundreds of cells, manual approaches are becoming increasingly impractical. We describe here the use of soft clustering to identify cell ROIs based on elemental contents, using data collected over a sample of the malaria parasite Plasmodium falciparum as a test case. Soft clustering was able to successfully classify regions in infected erythrocytes as "parasite," "food vacuole," "host," or "background." In contrast, hard clustering using the k-means algorithm was found to have difficulty in distinguishing cells from background. While initial tests showed convergence on two or three distinct solutions in 60% of the cells studied, subsequent modifications to the clustering routine improved results to yield 100% consistency in image segmentation. Data extracted using soft cluster ROIs were found to be as accurate as data extracted using manually defined ROIs, and analysis time was considerably improved.

Access to this energy resource requires the action of fungal and bacterial enzymes to break down the lignin polymer into a complex assortment of aromatic compounds that can be transported into the cells. To improve our understanding of the utilization of lignin by microorganisms, we characterized the molecular properties of solute binding proteins of ATP-binding cassette transporter proteins that interact with these compounds. A combination of functional screens and structural studies characterized the binding specificity of the solute binding proteins for aromatic compounds derived from lignin such as p-coumarate, 3-phenylpropionic acid and compounds with more complex ring substitutions. A ligand screen based on thermal stabilization identified several binding protein clusters that exhibit preferences based on the size or number of aromatic ring substituents. Multiple X-ray crystal structures of protein-ligand complexes for these clusters identified the molecular basis of the binding specificity for the lignin-derived aromatic compounds. The screens and structural data provide new functional assignments for these solute-binding proteins which can be used to infer their transport specificity. This knowledge of the functional roles and molecular binding specificity of these proteins will support the identification of the specific enzymes and regulatory proteins of peripheral pathways that funnel these compounds to central metabolic pathways and will improve the predictive power of sequence-based functional annotation methods for this family of proteins.Proteins 2013; 81:1709-1726.

They are designed on the basis of possible contamination events but often address only a narrow range in event conditions. The influence on their performance of conditions different from those assumed in the design generally is not considered. Using results from simulations done with network models for 11 actual WDSs, it is shown here that CWS performance for high-consequence events can degrade substantially (by an order of magnitude) when conditions such as contaminant toxicity and injection time differ from those used in the design. Generally, increasing the number of sensors does not reduce this sensitivity to changed conditions. The significance of uncertain conditions varies substantially among WDSs. As a consequence of performance changes that occur when conditions change, mean-case designs generally outperform worst-case designs when the objective is to minimize worst-case adverse effects over a range of conditions. The results of this work can be used to implement more robust designs for CWSs, while reducing computational requirements.

Because CA problems can naturally be divided into separate subtasks, parallel computing helps to speed up the computation time. This paper proposes a master/slave parallel computing architecture and studies the computation of CA in a large-scale power system through high performance computing, adopting a message passing interface for implementation. In particular, although the execution time of CA varies, there is a tradeoff between having an imbalanced workload and "paying" a synchronization penalty for parallel computing: either factor blocks the progress of scalability. The proposed layered dynamic scheduling method is effective to tackle the challenge of high synchronization cost and workload imbalance and have the potential to further scale for the N - 2 contingency analysis.

However, the number of studies assessing its water use remains limited. This work aims to analyze the impacts of forest-based biofuel on water resources and quality by using a water footprint approach. A method established here is tailored to the production system, which includes softwood, hardwood, and short-rotation woody crops. The method is then applied to selected areas in the southeastern region of the United States to quantify the county-level water footprint of the biofuel produced via a mixed alcohol gasification process, under several logistic systems, and at various refinery scales. The results indicate that the blue water sourced from surface or groundwater is minimal, at 2.4 liters per liter of biofuel (l/l). The regional-average green water (rainfall) footprint falls between 400 and 443 l/l. The biofuel pathway appears to have a low nitrogen grey water footprint averaging 25 l/l at the regional level, indicating minimal impacts on water quality. Feedstock mix plays a key role in determining the magnitude and the spatial distribution of the water footprint in these regions.

However, estimates of the quantity, decomposability, and combustibility of OC contained in permafrost-region soils remain highly uncertain, thereby limiting our ability to predict the release of greenhouse gases due to permafrost thawing. Substantial differences exist between empirical and modeling estimates of the quantity and distribution of permafrost-region soil OC, which contribute to large uncertainties in predictions of carbon-climate feedbacks under future warming. Here, we identify research challenges that constrain current assessments of the distribution and potential decomposability of soil OC stocks in the northern permafrost region and suggest priorities for future empirical and modeling studies to address these challenges.

To improve the hydraulic modeling of wire-wrap spacers in a rod bundle, a three-dimensional momentum source model (MSM) has been developed to model the anisotropic flow without the need to resolve the geometric details of the wire-wraps. The MSM is examined for 7-pin and 37-pin bundles steady-state simulations using the commercial CFD code STAR-CCM+. The calculated steady-state inter-subchannel cross flow velocities match very well in comparisons between bare bundles with the MSM applied and the wire-wrapped bundles with explicit geometry. The validity of the model is further verified by mesh and parameter sensitivity studies. Furthermore, the MSM is applied to a 61 -pin EBR-Il experimental subassembly for both steady state and PLOF transient simulations. Reasonably accurate predictions of temperature, pressure, and fluid flow velocities have been achieved using the MSM for both steady-state and transient conditions. Significant computing resources are saved with the MSM since it can be used on a much coarser computational mesh.

A comprehensive investigation of this electrolyte in a high-voltage graphite/LiNi sub(0.5)Mn sub(1.5)O sub(4) (LNMO) cell was carried out to evaluate its voltage stability under various charging conditions. Although the carbonate-based electrolyte was relatively stable when the graphite/LNMO cell was charged to 4.8 V at room temperature, the introduction of a constant-voltage charging step aggravated the oxidative decomposition of the electrolyte. Further increase in the cell charging voltage to 4.9 V or above and further increase in the temperature to 55 degree C caused cell performance to deteriorate dramatically.

In the presence of a 'medium' carbon charge and least-cost dispatch, units with CCS are operated with higher utilization rates than fossil energy plants without carbon capture, hence lowering CO sub(2) emissions. This path helps to lower the capital outlays that will be necessary to make a transition to a full portfolio of advanced low-carbon technologies. Required research, development and demonstration can be financed by a portion of the carbon charge revenue.

The structures of phases alpha , beta and gamma have been determined from the single-crystal data at pressures of 2.3(1), 11.1(1), and 14.6(1)GPa, respectively. The two new high-pressure transitions, very similar in their character to the P2 (sub 1) /c-C2/c transformation of cpx, make opx approximately as dense as cpx above 12.3(1)GPa and significantly change the elastic anisotropy of the crystal, with the [100] direction becoming almost twice as stiff as in the ambient alpha -opx phase. Both transformations involve mainly tetrahedral rotation, are reversible and are not expected to leave microstructural evidence that could be used as a geobarometric proxy. The high Fe (super 2+) content in Fs (sub 82) shifts the alpha -beta transition to slightly lower pressure, compared to MgSiO (sub 3) , and has a very dramatic effect on reducing the (meta) stability range of the beta -phase.

The resulting precipitates were characterized by TEM, SEM, XRD, IR spectroscopy, Mossbauer spectroscopy, EXAFS spectroscopy, and chemical analyses. The kinetics and the stoichiometry of oxidation were also determined. Chemical analyses revealed that all the P introduced was immobilized up to an introduced P/Fe molar ratio of 0.6-0.7. In the presence of excess phosphate, the maximum P/Fe ratio of the precipitates was found to be equal to about 0.86. Incorporation of phosphate hindered the sorption of dissolved carbonates, but favored the immobilization of monovalent cations such as Na or K. The number of OH (super -) ions per Fe atom introduced during the reaction decreased from 2 in the absence of P to about 1.5+ or -0.1 in the presence of excess phosphate. In all cases, no residual Fe(II) could be detected. In the absence of phosphate, the samples were composed of poorly crystallized ferrihydrite, lepidocrocite and goethite nanoparticles. Even just a small amount of phosphate (P/Fe=0.02) was sufficient to effectively restrict the formation of goethite. In contrast, the formation of lepidocrocite was detected by XRD for P/Fe ratios as high as 0.1. At higher P/Fe ratios, only non-crystalline particles were detected. For 0.10.5, a new category of particles with characteristic length scales larger than 10 nm appeared and became prominent as P/Fe increased. The transition was accompanied by a change in color of the suspension, from dark red to light yellow. For an introduced P/Fe ratio larger than 1, only the larger particles remained. As the introduced P/Fe ratio increased further, the incorporated P/Fe ratio increased only slightly. In contrast the size of the particles increased significantly, reaching a size larger than 50 nm in the presence of a large excess of PO (sub 4) (super 3-) . The kinetics of oxidation and hydrolysis were shown to obey a typical autocatalytic process in the presence as well as in the absence of PO (sub 4) (super 3-) .

For this, a large data set obtained by MPL systems operating at 532 nm during the 4 year period 2007-2010 was used to derive vertical profiles of AOD (z) by combining the corresponding AOD data as an input from an independent measurement using nearly colocated multifilter rotating shadowband radiometer (MFRSR) systems at five different U.S. Department of Energy Atmospheric Radiation Measurement (ARM) Program sites-three permanent sites (SGP in north-central Oklahoma, at 36.6 degree N, 97.5 degree W, 320 m; TWP-Darwin in the tropical western Pacific, at 12.4 degree S, 130.9 degree E, 30 m; and NSA at Barrow on the North Slope of Alaska, at 71.3 degree N, 156.6 degree W, 8 m) and two mobile facility sites (GRW at Graciosa Island in the Azores, at 39 degree N, 28 degree W, 15 m; and FKB in the Black Forest of Germany, at 48.5 degree N, 8.4 degree E, 511 m). Therefore, amount of data used in this study is constrained by the availability of the MFRSR data. The MPL raw data were averaged for 30 s in time and 30 m in altitude. The diurnally averaged AOD (z) profiles from 4 years were combined to obtain a multiyear vertical profile of AOD (z) climatology at various ARM sites, including diurnal, day-to-day, and seasonal variabilities. Most aerosols were found to be confined to 0-2 km (approximately the planetary boundary layer region) at all sites; however, all sites exhibited measurable aerosols well above the mixed layer, with different height maxima. The entire data set demonstrates large day-to-day variability at all sites. However, there is no significant diurnal variation in AOD (z) at all sites. Significant interannual variability was observed at the SGP site. Clear seasonal variations in AOD (z) profiles exist for all five sites, but seasonal behavior was distinct. Moreover, the different seasonal variability for the lower level (0 to ~2 km) versus the level above indicates a contribution of different types of air masses from different sources. The lower annual mean AOD (z) values (0.093 plus or minus 0.033 for daytime and 0.093 plus or minus 0.05 for nighttime) observed near the surface at GRW are not unexpected for maritime aerosols (mostly sea salt), and the corresponding higher values at SGP (0.118 plus or minus 0.038 for daytime and 0.11 plus or minus 0.05 for nighttime), FKB (0.124 plus or minus 0.042 for daytime and 0.127 plus or minus 0.047 for nighttime), and TWP (0.13 plus or minus 0.078 for daytime and 0.14 plus or minus 0.073 for nighttime) are usual for continental aerosols. The annual mean AOD (z) values observed near the surface during daytime and nighttime for NSA were 0.1 plus or minus 0.042 and 0.09 plus or minus 0.037, respectively. These results will aid the scientific community in understanding aerosol properties and boundary layer dynamics and in improving the incorporation of aerosol radiative effects into global climate models.

In prismatic reactors, hexagonal graphite bricks are used as reflectors and fuel bricks. In the reactor environment, graphite bricks experience high temperature and neutron dose. This leads to dimensional changes (swelling and or shrinkage) of these bricks. Irradiation dimensional changes may affect the structural integrity of the individual bricks as well as of the overall core. The present paper presents a generic procedure for stress analysis of prismatic core graphite components using graphite reflector as an example. The procedure is demonstrated through commercially available ABAQUS finite element software using the option of user material subroutine (UMAT). This paper considers General Atomics Gas Turbine-Modular Helium Reactor (GT-MHR) as a bench mark design to perform the time integrated stress analysis of a typical reflector brick considering realistic geometry, flux distribution and realistic irradiation material properties of transversely isotropic H-451 grade graphite.

This CMFD method employs standard Monte Carlo techniques to estimate nonlinear functionals (ratios of integrals), which are used in low-order CMFD equations to obtain the eigenvalue and discrete representations of the eigenfunction. In a "feedback" procedure, the Monte Carlo fission source is then modified to match the resulting CMFD fission source. The proposed new methods differ from the CMFD-accelerated Monte Carlo method only in the definition of the nonlinear functionals. The new methods are compared with the CMFD-accelerated Monte Carlo method for two high-dominance-ratio test problems. All of the hybrid methods rapidly converge the Monte Carlo fission source, enabling a large reduction in the number of inactive cycles. However, the new methods stabilize the fission source more efficiently than the CMFD-accelerated Monte Carlo method, enabling a reduction in the number of active cycles as well. Also, in all the hybrid methods, the apparent variance of the eigenfunction is nearly equal to the real variance, so the real statistical error is well estimated from a single calculation. This is a major advantage over the standard Monte Carlo method, in which the real variance is typically underestimated due to intercycle correlations.

The county-level analysis focuses on open-pond algae cultivation systems located in 17 states in the southern United States. Several scenarios were developed to examine the water availability for algae bio-oil production under various water resource mixing MWW and freshwater. The results of the analysis indicate that water availability can significantly affect the selection of an algal refinery site and therefore the potential production of algal bio-oil. The production of one liter of algal bio-oil requires 1036-1666L of water at the state level, in which 3% to 91% can be displaced by MWW , depending on the biorefinery location. This water requirement corresponds to a total of 25billion liters of bio-oil produced if the spatially and temporally available MWW effluent together with 10% of total available freshwater are used. The production of algal bio-oil is only 14% of estimated production under the assumption that all of the water demand can be fulfilled without any restriction. In addition, if only the spatially and temporally available effluent is used as the sole source of water, the total bio-oil production is estimated to be 9 billion liters. This study not only quantifies the water demands of the algal bio-oil, but it also elucidates the importance of taking water sustainability into account in the development of algal bio-oil.

One uncertainty in generating these projections is the choice of boundary forcing applied. In this study the Nested Regional Climate Model (NRCM) is used with a grid spacing of 12 km over the United States (excluding Hawaii) to dynamically downscale 2.5 degree National Centers for Environmental Prediction-U.S. Department of Energy Reanalysis-2 data, with different applications of spectral nudging (SN) for the boundary conditions. Nine numerical experiments for July 2005-each with different wavenumbers and nudging duration periods, applied to different model layers-evaluated the performance of SN in downscaling near-surface fields. The calculations were compared with the North America Regional Reanalysis dataset over four subregions of the contiguous 48 states. Results show significant differences with different wavenumbers, nudging duration periods, and nudging altitudes. The short-period SN with three waves, applied above 850 hPa, showed the highest skill in simulating precipitation, whereas whole-period SN produced a higher skill level and performed slightly better than short-period SN for surface temperature and 10-m wind, respectively. Differences in the performance of SN applied at different altitudes were not significant. On the basis of the comparisons for precipitation, surface temperature, and wind fields over entire contiguous states, whole-period nudging with six waves starting above 850 hPa for downscaling calculations for climate-related variables is recommended.

Eric Miller has stated that, much of the behavior of interest (in integrated urban modeling) involves the interaction among people (Miller 2006). The first such effects to be studied and incorporated in travel demand models were interactions within households, for example serving dependents, modeling joint trips, task allocation and joint scheduling (Miller and Roorda 2003). Several of these features are now common aspects of activity-based models implemented by planning agencies, e.g. the CT-RAMP family of models (Vovsha et al. 2010). However, it is clear that many types of interaction behavior can occur outside of the household context and that even within the household many types of interaction behavior still remain to be studied and modeled. The effects of agent-interactions and the constraints on behavior that they can impose are still only partially understood. In addition, while much work has been done on understanding the basic characteristics and formation processes of social networks outside of the household and their impacts on aspects of activitytravel (e.g. Habib and Carrasco 2011), comparatively little has been done to integrate these findings into activity-based model frameworks as suggested by Arentze and Timmermans (2008). More theoretical understanding of the behaviors that govern agent interactions, both within and outside of the household, and especially on how information exchange and decisionmaking occurs within agent groups is needed.

The nation's top government stories have recently focused on the "fiscal cliff," automatic spending cuts to the government, and budgets under continuing resolution. In addition, many U.S. Department of Energy (DOE) sites have switched from production to environmental cleanup mode, and the national laboratories are devoting less of their work to nuclear or radiological research and development. As a result, radiation protection organizations are facing uncertainty and significant budget pressures and are forced to do more with less; minimal staffing levels are expected to continue to support radiological work and maintain full compliance while under increasing scrutiny of regulators. Ideally, the radiation protection program was strong, robust, and mature prior to the budget pressures. It is easier to maintain a strong program than to create a new program or upgrade a program that needs significant revisions. However, even in the case of creating a new program, efficiencies can be gained by using a graded approach, establishing a good rapport with the regulator, working with stakeholders to develop acceptable approaches, and using approved consensus standards in lieu of developing new approaches. The presentation evaluates methods for upgrading or revising existing programs as well as for developing new programs, including outsourcing of specific program elements, increased usage of commercial vendors, and nontraditional staffing approaches. Lessons learned and the pros and cons from DOE case studies are presented.

The overall amount, rate, and form of C released to the atmosphere in a warmer world will influence the strength of the permafrost C feedback to climate change. We used a survey to quantify variability in the perception of the vulnerability of permafrost C to climate change. Experts were asked to provide quantitative estimates of permafrost change in response to four scenarios of warming. For the highest warming scenario (RCP 8.5), experts hypothesized that C release from permafrost zone soils could be 19-45 Pg C by 2040, 162-288 Pg C by 2100, and 381-616 Pg C by 2300 in CO (sub 2) equivalent using 100-year CH (sub 4) global warming potential (GWP). These values become 50 % larger using 20-year CH (sub 4) GWP, with a third to a half of expected climate forcing coming from CH (sub 4) even though CH (sub 4) was only 2.3 % of the expected C release. Experts projected that two-thirds of this release could be avoided under the lowest warming scenario (RCP 2.6). These results highlight the potential risk from permafrost thaw and serve to frame a hypothesis about the magnitude of this feedback to climate change. However, the level of emissions proposed here are unlikely to overshadow the impact of fossil fuel burning, which will continue to be the main source of C emissions and climate forcing.

AN - 1365056023; 23281210 AB - The unique ability of plasmonic nanostructures to guide, enhance, and manipulate subwavelength light offers multiple novel applications in chemical and biological sensing, imaging, and photonic microcircuitry. Here the reproducible, giant light amplification in multiscale plasmonic structures is demonstrated. These structures combine strongly coupled components of different dimensions and topologies that resonate at the same optical frequency. A light amplifier is constructed using a silver mirror carrying light-enhancing surface plasmons, dielectric gratings forming distributed Bragg cavities on top of the mirror, and gold nanoparticle arrays self-assembled into the grating grooves. By tuning the resonances of the individual components to the same frequency, multiple enhancement of the light intensity in the nanometer gaps between the particles is achieved. Using a monolayer of benzenethiol molecules on this structure, an average SERS enhancement factor ∼10⁸ is obtained, and the maximum enhancement in the interparticle hot-spots is ∼3 × 10¹⁰, in good agreement with FDTD calculations. The high enhancement factor, large density of well-ordered hot-spots, and good fidelity of the SERS signal make this design a promising platform for quantitative SERS sensing, optical detection, efficient solid state lighting, advanced photovoltaics, and other emerging photonic applications.

We investigated the decomposition mechanism of delithiated cathode materials at thermal abuse conditions using Li sub(1.1)[Ni sub(1/3)Mn sub(1/3)Co sub(1/3)] sub(0.9)O sub(2) as a model cathode material. An in-situ high-energy X-ray diffraction technique was established as an alternative to conventional thermal analysis techniques like differential scanning calorimetry and accelerating rate calorimetry. The X-ray diffraction data revealed that the thermal decomposition pathway of delithiated Li sub(1-x)[Ni sub(1/3)Mn sub(1/3)Co sub(1/3)] sub(0.9)O sub(2) strongly depended on the exposed chemical environment, like solvents and lithium salts. A phase transformation of dry delithiated Li sub(1-x)[Ni sub(1/3)Mn sub(1/3)Co sub(1/3)] sub(0.9)O sub(2) was observed at about 278 degree C, and its onset temperature was reduced to about 197 degree C with the presence of the electrolyte. It is suggested that the reduction in thermal stability is possibly related to proton intercalation into the delithiated material. An in-situ high-energy X-ray diffraction technique is deployed to investigate the thermal decomposition of a delithiated Li sub(1-x)[Ni sub(1/3)Mn sub(1/3)Co sub(1/3)] sub(0.9)O sub(2) cathode during thermal abuse. A mechanism based on proton intercalation is proposed to explain the negative impact of LiPF sub(6) on the thermal stability of Li sub(1-x)[Ni sub(1/3)Mn sub(1/3)Co sub(1/3)] sub(0.9)O sub(2).

It has received extensive in-pile and out-of-pile tests and analyses, so ample data have been accumulated. The major fuel geometry for an MTR type research and test reactor is a plate, containing a fuel meat that comprises fuel particles dispersed in an inert matrix such as aluminum. The most popular cladding material is aluminum alloy. Cladding is directly bonded to the fuel meat. The main performance topics dealt with for an MTR type fuel plate are plate dimension changes and fuel temperature. Thermal properties of the non-irradiated fuel constituents and cladding are well known. However, during irradiation, thermal degradation of the fuel meat and cladding occurs. This paper summarizes the modeling methods to estimate the thermal degradation of U-Mo dispersion in Al, designated U-Mo/Al hereafter, during irradiation.

This mechanism permits U-Mo fuel to achieve high burnup by effectively relieving stresses at the fuel end region, where peak stresses are otherwise expected because peak fission product induced fuel swelling occurs there. ABAQUS FEA was employed to examine whether the observed phenomenon can be simulated using physical-mechanical data available in the literature. The simulation results obtained for several plates with different fuel fabrication and loading scheme showed that the measured data were able to be simulated with a reasonable creep rate coefficient. The obtained creep rate constant lies between values for pure uranium and MOX, and is greater than all other ceramic uranium fuels.

Currently, the predictive mean residence time relies on an empirical entrainment coefficient with a range in variance due to the absence of hydraulic and geomorphic quantities driving mass exchange. Two empirically derived relationships are presented for the mean residence time of lateral cavities-a prevalent and widely recognized type of transient storage-in gravel-bed rivers and streams that incorporates hydraulic and geomorphic parameters. The relationships are applicable for gravel-bed rivers and streams with a range of cavity width to length (W/L) aspect ratios (0.2-0.75), shape, and Reynolds numbers (Re, ranging from 1.0 X 10 (super 4) to 1.0 X 10 (super 7) ). The relationships equate normalized mean residence time to nondimensional quantities: Froude number, Re, W/L, depth ratio (ratio of cavity to shear layer depth), roughness factor (ratio of shear to channel velocity), and shape factor (representing degree of cavity equidimensionality). One relationship excludes bed roughness (equation (13)) and the other includes bed roughness (equation (14)). The empirically derived relationships have been verified for conservative tracers (R (super 2) of 0.83) within a range of flow and geometry conditions. Topics warranting future research are testing the empirical relationship that includes the roughness factor using parameters measured in the vicinity of the cavity to reduce the variance in the correlation, and further development of the relationship for nonconservative transport.

Large differences were found in all code predictions. However, considering the large uncertainty of the TED temperature measurements in the experiments, the CFD simulation results are reasonably well in agreement with the experiments. Additionally, the CFD temperature predications are overestimated at the inner pins but underestimated at the outer pins if a fixed heat flux boundary condition is used. It can be concluded that the detailed conjugate heat transfer should be modeled to account for the heat conduction in the fuel pins for more accurate temperature predictions in the wire-wrapped pin-bundles.

The dominant part of that cost and of the overall uncertainty of the cost of electricity comes generally from the capital cost of the nuclear reactors. Included in the AFC CBR is an estimate of the overnight capital cost for the fully deployed steady state systems. The challenge is to develop an estimate that is accurate and defensible based on the available information which often comes from data that are not representative of these conditions. The available data needs to be transformed into the specific overnight capital cost (SOCC) in the appropriate constant year dollars for the technology, scale, and other conditions of the final full scale (FS) Nth-of-a-kind (NOAK) commercial power plant. This requires a number of adjustments that can be quite uncertain. This paper reviews a proposed methodology in the 2012 update to the AFC CBR to address this challenge in a way that clearly documents the assumptions made to estimate this parameter, to ensure consistency between reactor concepts and also to provide other benefits to the users such as the ability to change those assumptions if desired. Also include is a summary of the proposed reactor costs in the 2012 update to the AFC CBR.

Moreover, it is currently being proposed as metallic fuel candidates for fast reactors due to its ideal thermal properties. More recent efforts were also spent to investigate the behaviors of this material along with U-Zr alloys under fast reactor conditions. Although microstructures and behaviors of U-Mo particles under irradiations in dispersion fuels have been quite extensively investigated with transmission electron microscopy (TEM) at RERTR temperature regimes (usually no higher than 200 degree C), the behaviors of monolithic U-Mo alloys have not been well understood at this microscopic level.

With a supported research background on a variety of options including the strengths and weaknesses of the various fuel cycle options we can make optimal decisions for future political and economic factors. Such research has been carried out using the Code for Advanced Fuel Cycle Analysis (CAFCA). From its early development in the comparison of two advanced fuel cycle options to its current status at multi cycle and multi reactor type optimization, CAFCA has become a resource for analysis of the intricacies of the nuclear fuel cycle which require a dynamic study.

A critical requirement for these candidate fuels is stable swelling behavior over their expected lifetime. In-reactor deformation of these materials is primarily driven by irradiation induced swelling where the primary component is fission gas (Xe and Kr) generated by decay of the primary fission products. An understanding of the behavior of the gas in the material as a function of design operating conditions, such as temperature and fission-rate, is greatly leveraged by the development of mechanistic models. Due to the inherent uncertainty of proposed behavioral mechanisms resulting from the unavailability of critical materials properties of the irradiated material, these models require extensive validation. In-reactor experiments and the associated post-irradiation examinations are expensive. In addition, it is very difficult to validate single effect mechanisms from a multivariate environment. For that reason, ion implantation experiments are often used to facilitate the validation process. However, the interpretation of ion implantation experiments and the mapping of the observed phenomena to an in-reactor environment is complicated by the non-homogeneous nature of the implantation process, thin specimen size that introduces surface effects, as well as operating conditions that are outside the range of in-reactor design specifications.

While development of hardware and computing techniques enables models of high fidelity and resolution, the data obtained by running such codes has significant computational cost. We resolve the contradiction between the need for data, and the cost of simulation by querying the simulation code at multiple levels of fidelity and relating multi-fidelity data by statistical models. Previously, we presented elements of analysis on multi-fidelity training data. We are now demonstrating effectiveness on codes of higher complexity, with a fluid mechanics solver Nek5000 used as an example.

The application of Eq. 3 assumes that the experimental prompt decay constant is corrected by a correction factor calculated by numerical simulations. The correction factor takes also into account the longer neutron generation time in the reflector zone.

The effect of grain subdivision is to effectively enhance fission gas bubble (FGB) swelling due to increased grain boundaries. Inter-granular FGB swelling, i.e., FGB formation and growth at the grain boundaries, is much larger than the intra-granular FGB swelling. Recrystallized fuel volume fractions of U-Mo fuels irradiated to fission densities reaching 5.7 x 10(21) f/cm(3) were measured. Analytical expressions of recrystallization kinetics of U-Mo fuel during irradiation have been developed through the usage of the Avrami equation, a phenomenological equation which is also used to describe similar typical transformation reactions, such as new phase formation. In this work, we present a novel FGB swelling model of U-Mo fuel that is expressed in terms of Mo content, extent of cold work (fuel powder fabrication method), and fission density.

The phase was characterized by SEM, EBSD, synchrotron micro-Laue diffraction, micro-Raman, and EPMA. The mean chemical composition of the type kangite is (wt%) TiO (sub 2) 36.6, Sc (sub 2) O (sub 3) 26.4, ZrO (sub 2) 11.3, Al (sub 2) O (sub 3) 7.0, Y (sub 2) O (sub 3) 5.4, CaO 3.9, MgO 3.14, Dy (sub 2) O (sub 3) 1.8, SiO (sub 2) 1.7, V (sub 2) O (sub 3) 1.31, Er (sub 2) O (sub 3) 0.92, FeO 0.8, Gd (sub 2) O (sub 3) 0.60, Ho (sub 2) O (sub 3) 0.40, Tb (sub 2) O (sub 3) 0.18, Cr (sub 2) O (sub 3) 0.09, ThO (sub 2) 0.04, O -0.3, sum 101.28, which leads to an empirical formula calculated on the basis of 3 O atoms of [(Sc (sub 0.54) Al (sub 0.16) Y (sub 0.07) V (sub 0.03) Gd (sub 0.01) Dy (sub 0.01) Er (sub 0.01) ) (super 3+) (sub Sigma 0.83) (Ti (sub 0.66) Zr (sub 0.13) ) (super 4+) (sub Sigma 0.79) (Mg (sub 0.11) Ca (sub 0.06) Fe (sub 0.02) ) (super 2+) (sub Sigma 0.19) [] (sub 0.19) ] (sub Sigma 2.00) O (sub 3) . Synchrotron micro-Laue diffraction (i.e., an energy scan by a high-flux X-ray monochromatic beam) on one type domain at submicrometer resolution revealed that kangite has a cation-deficient Ia3 bixbyite-type cubic structure. The cell parameters are a=9.842(1) Aa, V=953.3(1) Aa (super 3) , Z=16, which leads to a calculated density of 3.879 g/cm (super 3) . Kangite is a new ultra-refractory mineral, likely originating through low-temperature oxidation of a Sc-,Ti (super 3+) -enriched high-temperature condensate oxide dating to the birth of the Solar System.

Four scenarios were considered. The two current uses considered were on-site industrial use and off-site residential use with farming. The two future uses (i.e., after an institutional control period of100 y) were on-site recreational use and on-site residential use with farming. The RESRAD-OFFSITE code was used for the current-use off-site residential/farming scenario and RESRAD (onsite) was used for the other three scenarios. Contaminants of concern were identified from the past operations conducted in the buildings and the actual characterization done at the site. Derived Concentration Guideline Levels were developed for all four scenarios using deterministic and probabilistic approaches, which include both "peak-of-the-means" and "mean-of-the-peaks" analyses. The future-use on-site residential/farming scenario resulted in the most restrictive Derived Concentration Guideline Levels for most radionuclides.

In addition, agriculture could influence above- and below-ground carbon storage. Development of models that represent agriculture is necessary to address these impacts. We have developed an approach to integrate agriculture representations for three crop types - maize, soybean, and spring wheat - into the coupled carbon-nitrogen version of the Community Land Model (CLM), to help address these questions. Here we present the new model, CLM-Crop, validated against observations from two AmeriFlux sites in the United States, planted with maize and soybean. Seasonal carbon fluxes compared well with field measurements for soybean, but not as well for maize. CLM-Crop yields were comparable with observations in countries such as the United States, Argentina, and China, although the generality of the crop model and its lack of technology and irrigation made direct comparison difficult. CLM-Crop was compared against the standard CLM3.5, which simulates crops as grass. The comparison showed improvement in gross primary productivity in regions where crops are the dominant vegetation cover. Crop yields and productivity were negatively correlated with temperature and positively correlated with precipitation, in agreement with other modeling studies. In case studies with the new crop model looking at impacts of residue management and planting date on crop yield, we found that increased residue returned to the litter pool increased crop yield, while reduced residue returns resulted in yield decreases. Using climate controls to signal planting date caused different responses in different crops. Maize and soybean had opposite reactions: when low temperature threshold resulted in early planting, maize responded with a loss of yield, but soybean yields increased. Our improvements in CLM demonstrate a new capability in the model - simulating agriculture in a realistic way, complete with fertilizer and residue management practices. Results are encouraging, with improved representation of human influences on the land surface and the potentially resulting climate impacts.

Humans have emitted Hg to the atmosphere for millennia, and this Hg has deposited and accumulated into ecosystems globally. Here we present a global biogeochemical model with fully coupled atmospheric, terrestrial, and oceanic Hg reservoirs to better understand human influence on Hg cycling and timescales for responses. We drive the model with a historical inventory of anthropogenic emissions from 2000 BC to present. Results show that anthropogenic perturbations introduced to surface reservoirs (atmosphere, ocean, or terrestrial) accumulate and persist in the subsurface ocean for decades to centuries. The simulated present-day atmosphere is enriched by a factor of 2.6 relative to 1840 levels, consistent with sediment archives, and by a factor of 7.5 relative to natural levels (2000 BC). Legacy anthropogenic Hg re-emitted from surface reservoirs accounts for 60% of present-day atmospheric deposition, compared to 27% from primary anthropogenic emissions, and 13% from natural sources. We find that only 17% of the present-day Hg in the surface ocean is natural and that half of its anthropogenic enrichment originates from pre-1950 emissions. Although Asia is presently the dominant contributor to primary anthropogenic emissions, only 17% of the surface ocean reservoir is of Asian anthropogenic origin, as compared to 30% of North American and European origin. The accumulated burden of legacy anthropogenic Hg means that future deposition will increase even if primary anthropogenic emissions are held constant.

Component-based software engineering enables the integration of plug-and-play components, but significant additional challenges must be addressed in any specific domain in order to produce a usable development and simulation environment that also encourages contributions and adoption by entire communities. In this paper we describe the challenges in creating a coupling environment for Earth-surface process modeling and the innovative approach that we have developed to address them within the Community Surface Dynamics Modeling System.

In California, California sage scrub (CSS) is one of the most endangered plant communities in the US and requires close monitoring in order to conserve this important biological resource. We investigate the utility of remote-sensing approaches-object-based image analysis applied to pansharpened QuickBird imagery (QBPS/OBIA) and multiple endmember spectral mixture analysis (MESMA) applied to SPOT imagery (SPOT/MESMA)-for estimating fractional cover of true shrub, subshrub, herb, and bare ground within CSS communities of southern California. We also explore the effectiveness of life-form cover maps for assessing CSS conditions. Overall and combined shrub cover (i.e., true shrub and subshrub) were estimated more accurately using QBPS/OBIA (mean absolute error or MAE, 8.9 %) than SPOT/MESMA (MAE, 11.4 %). Life-form cover from QBPS/OBIA at a 2525 m grid cell size seems most desirable for assessing CSS because of its higher accuracy and spatial detail in cover estimates and amenability to extracting other vegetation information (e.g., size, shape, and density of shrub patches). Maps derived from SPOT/MESMA at a 5050 m scale are effective for retrospective analysis of life-form cover change because their comparable accuracies to QBPS/OBIA and availability of SPOT archives data dating back to the mid-1980s. The framework in this study can be applied to other physiognomically comparable shrubland communities.

In an effort to understand how its interactions with biological surfaces may affect its movement in the environment, we investigated neptunyl interactions with Bacillus subtilis endospores and their exudates. The exudates were dominated by dipicolinic acid. Spectrophotometric investigations of the chemical form of neptunyl in exudate solutions are consistent with the formation of 1:1 neptunyl-dipicolinate complexes. Using neptunyl-endospore adsorption data and spectrophotometric measurements of neptunyl-dipicolinate complexes, we determined thermodynamic stability constants for both species. Neptunyl adsorption onto the endospore surface decreased with an increasing pH, which corresponds to increasing aqueous complexation of neptunyl by dipicolinate. Adsorption was also highly ionic strength dependent with adsorption increasing as ionic strength decreased. With stability constants determined in this work, we compared controls on neptunyl partitioning in a simulated system with B. subtilis endospores, vegetative cells, and generic natural organic matter. Neptunyl complexation by B. subtilis endospore exudates exerted the greatest biological control in the simulated systems. Abstract Copyright (2013) Elsevier, B.V.

This article discusses some of the progress that scientists have made with the use of so-called "omic" techniques (metagenomics, metatranscriptomics, and metaproteomics) and the limitations and major challenges these approaches are currently facing. These 'omic methods have been used to describe the taxonomic structure of microbial communities in different environments and to discover new genes and enzymes of industrial and medical interest. However, microbial community structure varies in different spatial and temporal scales and none of the 'omic techniques are individually able to elucidate the complex aspects of microbial communities and ecosystems. In this article we highlight the importance of a spatiotemporal sampling design, together with a multilevel 'omic approach and a community analysis strategy (association networks and modeling) to examine and predict interacting microbial communities and their impact on the environment.

We physically isolated particulate (>53 mu m), silt-, and clay-sized organic matter from soils collected over two decades from a perennial C (sub 3) grassland established on long-term agricultural soil with a predominantly C (sub 4) isotopic signature. Silt- and clay-sized fractions were then subjected to a sequential chemical fractionation (acid hydrolysis followed by peroxide oxidation) to isolate long-lived C pools. We quantified (super 14) C and the natural (super 13) C isotopic label in the resulting fractions to identify and evaluate pools responsible for long-lived SOM. After removal of particulate organic matter ( approximately 14% of bulk soil C) sequential chemical treatment removed 80% of mineral-associated C. In all mineral-associated fractions, at least 55% of C (sub 4) -derived C was retained 32 years after the switch to C (sub 3) inputs. However, C (sub 3) -C increased substantially beginning approximately 25 years after the switch. Radiocarbon-based turnover times ranged from roughly 1200-3000 years for chemically resistant mineral-associated pools, although some pools turned over faster under C (sub 3) grassland than in a reference agricultural field, indicating that new material had entered some pools as early as 14 years after the vegetation switch. These findings provide further evidence that SOM chemistry does not always reflect SOM longevity and resistance to microbial decomposition. Even measureable SOM fractions that have extremely long mean turnover times (>1500 years) can have a substantial component that is dynamic over much shorter timescales.

SiO is preferable because of its high capacity and the Sn-Fe-C alloys could be used as a buffer material to extend the cycle life of cells. Rather than expensive and toxic cobalt, we selected cheap and environmentally benign iron instead. The aim of this work is to find the optimal point by tuning the composition of Sn-Fe-C in the hope of obtaining better electrochemical performance. Different combinations were studied by high-energy X-ray diffraction and electrochemical methods. The results indicated that carbon can improve the cycle life, the amount of iron affects phase formation greatly, and the FeSn sub(2) phase should be avoided because of its detrimental effect on cycle life. The 50 wt% SiO-50 wt% Sn sub(30)Fe sub(30)C sub(4 0) composition was studied using the pair distribution function and Mossbauer spectroscopy.

Optimal siting of offshore facilities requires accurate knowledge of the relationship between distance and the visibility of wind turbines. Past assessments of offshore wind turbine visibility were based on smaller turbines and facilities in use at the time and underestimate visibility for current projects, which use more and larger larger turbines. This study is a preliminary assessment of the visibility of offshore wind facilities in the United Kingdom. Study objectives included identifying the maximum distances the facilities could be seen in both daytime and nighttime views and assessing the effect of distance on visual contrasts associated with the facilities. Results showed that small to moderately sized facilities were visible to the unaided eye at distances greater than 42 km [26 miles (mi)], with turbine blade movement visible up to 39 km (24 mi). At night, aerial hazard navigation lighting was visible at distances greater than 39 km (24 mi). The observed wind facilities were judged to be a major focus of visual attention at distances up to 16 km (10 mi), were noticeable to casual observers at distances of almost 29 km (18 mi), and were visible with extended or concentrated viewing at distances beyond 40 km (25 mi).

Often phage genes occur in clusters of atypical G+C content that reflect integration of the foreign DNA. However, some phage genes occur in isolation without other phage gene neighbors, probably resulting from horizontal gene transfer. In these cases, the phage gene product is unlikely to function as a component of a mature phage particle, and instead may have been co-opted by the host for its own benefit. The product of one such gene from Salmonella enterica serovar Typhimurium, STM3605, encodes a protein with modest sequence similarity to phage-like lysozyme (N-acetylmuramidase) but appears to lack essential catalytic residues that are strictly conserved in all lysozymes. Close homologs in other bacteria share this characteristic. The structure of the STM3605 protein was characterized by X-ray crystallography, and functional assays showed that it is a stable, folded protein whose structure closely resembles lysozyme. However, this protein is unlikely to hydrolyze peptidoglycan. Instead, STM3605 is presumed to have evolved an alternative function because it shows some lytic activity and partitions to micelles.

PTS-dependent translocation through the cell membrane is coupled with phosphorylation of the incoming sugar. After translocation through the bacterial membrane, the beta -glycosidic bond in 6'-P- beta -glucoside is cleaved, releasing 6-P- beta -glucose and the respective aglycon. This reaction is catalyzed by 6-P- beta -glucosidases, which belong to two glycoside hydrolase (GH) families: GH1 and GH4. Here, the high-resolution crystal structures of GH1 6-P- beta -glucosidases from Lactobacillus plantarum (LpPbg1) and Streptococcus mutans (SmBgl) and their complexes with ligands are reported. Both enzymes show hydrolytic activity towards 6'-P- beta -glucosides. The LpPbg1 structure has been determined in an apo form as well as in a complex with phosphate and a glucose molecule corresponding to the aglycon molecule. The S. mutans homolog contains a sulfate ion in the phosphate-dedicated subcavity. SmBgl was also crystallized in the presence of the reaction product 6-P- beta -glucose. For a mutated variant of the S. mutans enzyme (E375Q), the structure of a 6'-P-salicin complex has also been determined. The presence of natural ligands enabled the definition of the structural elements that are responsible for substrate recognition during catalysis.

This study presents the successful pilot test conducted with continuous but varying feed conditions over a protracted period. The UF membrane process consistently provided a constant permeate quality at all tested operating conditions, virtually independent of the feed water characteristics and the feed Hg concentration (0.5-22.7 ppt). The treatment target of less than 1.3 ppt of Hg was met and exceeded for all tested conditions during the pilot study. Turbidity measurements were <0.5 NTU (with a MDL of 0.5 NTU) 85% of the time and <0.16 NTU 95% of the time when analyzed on-line. The TMP values were below the specification of (negative) 7-12 psi at all tested conditions during the pilot-study. Weekly maintenance cleans and monthly clean in place (CIP) events were very effective in consistently restoring the membrane permeability during the pilot-study.

Protein assembly in the envelope of B. anthracis requires S-layer homology domains (SLH) within S-layer proteins and S-layer-associated proteins (BSLs), which associate with the secondary cell wall polysaccharide (SCWP), an acetylated carbohydrate that is tethered to peptidoglycan. Here, we investigated the contributions of two putative acetyltransferases, PatA1 and PatA2, on SCWP acetylation and S-layer assembly. We show that mutations in patA1 and patA2 affect the chain lengths of B. anthracis vegetative forms and perturb the deposition of the BslO murein hydrolase at cell division septa. The patA1 and patA2 mutants are defective for the assembly of EA1 in the envelope but retain the ability of S-layer formation with Sap. SCWP isolated from the patA1 patA2 mutant lacked acetyl moieties identified in wild-type polysaccharide and failed to associate with the SLH domains of EA1. A model is discussed whereby patA1- and patA2-mediated acetylation of SCWP enables the deposition of EA1 as well as BslO near the septal region of the B. anthracis envelope.

Prior studies of the Yellowstone system using stable noble gas isotopes show that the thermal fluids contain a mixture of atmospheric, mantle, and crustal components. Noble gas radionuclide measurements provide complementary chronometric information regarding subsurface residence times of thermal fluids, from decay of (super 81) Kr and (super 85) Kr as well as in situ production and release of nucleogenic (super 39) Ar and radiogenic (super 40) Ar* in the reservoir rock. Argon-39 isotopic abundances in air-corrected samples exceed those of atmospheric Ar by 705 to 1217%, indicating substantial Ar contribution to thermal fluids by fluid-rock interaction. Upper limits on deep thermal fluid mean residence times, estimated from (super 39) Ar/ (super 40) Ar* ratios, are about 100kyr for features in the Gibbon and Norris Geyser Basin areas, and is about 30kyr in Lower Geyser Basin, with the key assumption that the fluid acquires its crustal component of Ar in Quaternary volcanic rock of the Yellowstone Caldera. Input of crustal Ar from older aquifer rocks would reduce these apparent mean residence times.

AN - 1287888132; 23346956 AB - Controlled assembly of nanoparticles into asymmetric configurations is of great interest due to their novel properties and promising applications. In this Article, we report a generic strategy for the synthesis of dimer nanoclusters and asymmetric nanoassemblies by using magnetic colloidal substrates, on which tailored surface modification and controlled physical confinement are applied. The modularity of our approach facilitates the fabrication of asymmetric nanostructures with varying sizes, shapes, compositions, surface chemistry, and surface hydrophobicity. Success in the syntheses sheds a light on the versatility of our strategy in rationally designing and synthesizing asymmetric nanostructures with tailored properties and functionalities.

Despite the simple structure, some of these materials like troilite (FeS) exhibit complex phase diagrams and rich polymorphism, involving significant changes in interatomic bonding and physical properties. NiP (oP16) represents one of the two principal structure distortions found in the nickel arsenide family and is characterized by P-P bonding interactions that lead to the formation of P (sub 2) dimers. In the current study, the single-crystal synchrotron X-ray diffraction technique, aided by first principles density functional theory (DFT) calculations, has been applied to examine the compression behavior of NiP up to 30 GPa. Two new reversible displacive phase transitions leading to orthorhombic high-pressure phases with Pearson symbols oP40 and oC24 were found to occur at approximately 8.5 and 25.0 GPa, respectively. The oP40 phase has the primitive Pnma space group with unit cell a = 4.7729(5) Aa, b = 16.6619(12) Aa, and c = 5.8071(8) Aa at 16.3(1) GPa and is a superstructure of the ambient oP16 phase with multiplicity of 2.5. The oC24 phase has the acentric Cmc2 (sub 1) space group with unit cell a = 9.695(6) Aa, b = 5.7101(9) Aa, and c = 4.7438(6) Aa at 28.5(1) GPa and is a superstructure of the oP16 phase with multiplicity of 1.5. DFT calculations fully support the observed sequence of phase transitions. The two new phases constitute logical next stages of P sublattice polymerization, in which the dilution of the P (sub 3) units, introduced in the first high-pressure phase, decreases, leading to compositions of Ni (sub 20) (P (sub 3) ) (sub 4) (P (sub 2) ) (sub 4) and Ni (sub 12) (P (sub 3) ) (sub 4) , and provide important clues to understanding of phase relations and transformation pathways in the NiAs family.

To address the energy security and urban air-pollution concerns that emerge from rapid vehicle population growth, China has initiated the Thousands of Vehicles, Tens of Cities (TVTC) Program to accelerate the new energy vehicle (NEV) commercialization. In this paper, we summarize the efforts made by the Chinese government since 1995 in the areas of research and development, demonstration, and communalization of NEVs; evaluate the progress of NEV demonstration; and provide some recommendations for future development. Our analysis has determined that the deployment of NEVs for the TVTC Program is lagging behind the original plan and, on average, only 26-36% of the goals have been attained by October 2011. Although China has approved many NEV models for sale, significantly more than 50% of them are not in production. On the other hand, stimulated by the policy shift, electric vehicle production has increased considerably, thereby contributing 23% and 44% of the total NEV production in 2010 and 2011, respectively. Additionally, because of the constraints imposed by price and technology maturity, lead-acid battery technology is a substantial factor in the high-volume sales of top NEV car models.

Further, insertion of LcrV-capped needles from a calcium-rich environment into host cells may trigger the low-calcium signal for effector translocation. Here, we used a genetic approach to test the hypothesis that the needle cap responds to the low-calcium signal by promoting injectisome assembly. Growth restriction of Yersinia pestis in the absence of calcium (low-calcium response [LCR+] phenotype) was exploited to isolate dominant negative lcrV alleles with missense mutations in its amber stop codon (lcrV*327). The addition of at least four amino acids or the eight-residue Strep tag to the C terminus was sufficient to generate an LCR- phenotype, with variant LcrV capping type III needles that cannot assemble the YopD injectisome component. The C-terminal Strep tag appears buried within the cap structure, blocking effector transport even in Y. pestis yscF variants that are otherwise calcium blind, a constitutive type III secretion phenotype. Thus, LcrV*327 mutants arrest the needle cap in a state in which it cannot respond to the low-calcium signal with either injectisome assembly or the activation of type III secretion. Insertion of the Strep tag at other positions of LcrV produced variants with wild-type LCR+, LCR-, or dominant negative LCR- phenotypes, thereby allowing us to identify discrete sites within LcrV as essential for its attributes as a secretion substrate, needle cap, and injectisome assembly factor.

Our approach is unique because the dynamics of the iron atoms are monitored. This process is described by the Lamb-Mossbauer factor, which is related to the mean-square displacement of the iron atoms. Focused synchrotron radiation with 1 meV bandwidth passes through a laser-heated (super 57) Fe sample inside a diamond-anvil cell, and the characteristic SMS time signature vanishes when melting occurs. At our highest compression measurement and considering thermal pressure, we find the melting point of iron to be T (sub M) =3025+ or -115 K at P=82+ or -5 GPa. When compared with previously reported melting points for iron using static compression methods with different criteria for melting, our melting trend defines a steeper positive slope as a function of pressure. The obtained melting temperatures represent a significant step toward a reliable melting curve of iron at Earth's core conditions. For other terrestrial planets possessing cores with liquid portions rich in metallic iron, such as Mercury and Mars, the higher melting temperatures for compressed iron may imply warmer internal temperatures.

This research shows that employing an [alpha]-MnO sub(2)/ramsdellite-Mn O sub(2) electrode/electrocatalyst results in the formation of lithium-oxide-like discharge products in propylene carbonate, which has been reported to be extremely susceptible to decomposition. X-ray photoelectron data have shown that what are likely lithium oxides (Li sub(2)O sub(2) and Li sub(2)O) appear to form and decompose on the air electrode surface, particularly at the MnO sub(2) surface, while Li sub(2)CO sub(3) is also formed. By contrast, cells without [alpha]-MnO sub(2)/ramsdellite-Mn O sub(2) fail rapidly in electrochemical cycling, likely due to the differences in the discharge product. Relatively high electrode capacities, up to 5000 mAh/g (carbon + electrode/electrocatalyst), have been achieved with non-optimized air electrodes. Insights into reversible insertion reactions of lithium, lithium peroxide (Li sub(2)O sub(2)) and lithium oxide (Li sub(2)O) in the tunnels of [alpha]-MnO sub(2), and the reaction of lithium with ramsdellite-MnO sub(2), as determined by first principles density functional theory calculations, are used to provide a possible explanation for some of the observed results. It is speculated that a Li sub(2)O-stabilized and partially-lithiated electrode component, 0.15Li sub(2)O.[alpha]-Li sub(x)MnO sub(2), that has Mn super(4+/3+) character may facilitate the Li sub(2)O sub(2)/Li sub(2)O discharge/charge chemistries providing dual electrode/electrocatalyst functionality. Lithium-oxygen batteries offer extremely attractive theoretical energy densities and thus represent a rapidly emerging area of research. Developing efficient, long-lasting Li-O sub(2) cells will require many technological improvements. Regarding the charge hysteresis, this approach develops transition metal oxide electrocatalysts that have a natural affinity to form compounds with Li sub(2)O, the ultimate discharge product in a non-aqueous Li-O sub(2) cell.

Highly ordered crystalline Si particles are deposited onto graphene sheets by using a liquid chlorosilane as Si source. The Si-graphene composite exhibits high utilization of Si in charge-discharge processes. The capacity retention of 90% after 500full cycles and an average Coulombic efficiency in excess of 99.5% are achieved in half cells. Moreover, atomic layer deposition (ALD) Al sub(2)O sub(3) coating is directly applied on the Si-graphene electrode, which greatly suppresses the side reactions between the electrode and electrolyte, resulting in the enhancement in initial Coulombic efficiency and reversible capacity. Finally, a 3.6V full cell device is demonstrated, which works very well by combining a Si-graphene anode with a Li-excess layer-structured composite Li sub(1.2)Ni sub(0.2)Mn sub(0.6)O sub(2) cathode. This approach is very promising for realizing a high-energy lithium-ion battery. Acting the part: The deposition of crystalline silicon particles onto graphene sheets provides a composite anode material for lithium ion battery. The composite exhibits a high utilization of Si, ultrastable cycling properties, and a high Coulombic efficiency. ALD Al sub(2)O sub(3) coating suppresses side reactions between Si-graphene anode and electrolyte. A 3.6V full cell combining the Si-graphene anode and a Li sub(1.2)Ni sub(0.2)Mn sub(0.6)O sub(2) cathode works very well.

This paper describes an ongoing field study being conducted by the U.S. Department of Agriculture at a test site in Nebraska, in which selective vegetation plantings are being used to mitigate the impacts of contaminated groundwater discharge to a naturally gaining stream. At the test site, preliminary studies demonstrated that the naturally occurring vegetation along a gaining stream was capable of intercepting several contaminants identified in the groundwater feeding the stream. The contaminants of concern in the groundwater included carbon tetrachloride, as a result of historic grain storage and fumigation activities upgradient of the headwaters, and nitrate contributed from surrounding agricultural lands. To capitalize on these observations, the natural vegetation was augmented by the planting of selected dry-land species, and the creation of a in-stream wetland, in an 8-acre area surrounding the headwaters area. To document the effects of the vegetation enhancements on contaminant migration via the groundwater-surface water interface, a comprehensive strategy has been implemented to monitor the site since 2006. The key elements of this multi-faceted program have included: hydrologic monitoring, involving continuous tracking of water levels and stream flow rates; the measurement of sap flow rates to investigate the movement of fluids within the vegetation; and direct water and vegetation sampling for contaminant and geochemical analyses. The investigation results from the past seven years quantitatively demonstrate that significant and beneficial changes have occurred in the hydrologic, geochemical, and biological characteristics of the groundwater and surface water environments, and in the transport, transformation, and reduction of contaminants within these systems, in response to the vegetation enhancements. The experience gained from this test has provided both fundamental and practical information pertinent to the application of enhanced vegetation (and wetlands), for manipulation of the hydrologic processes, and potential contaminant mitigation, in other similar near-surface environments.

However, each vehicle type incurs a significant initial cost penalty compared with a conventional vehicle powered by an internal combustion engine. Three PHEV cars and an AEV car are selected to assess cost-effectiveness from the consumers' perspective. Daily travel to and from work is isolated from other vehicle travel data from the U.S. National Household Travel Survey, and five daily distance categories are investigated. Three driving cycle runs are used: one developed by following cars in Los Angeles, California, in 1992, the Worldwide Harmonized Light-Duty Test Cycle, and a real driving record selected from the Kansas City metropolitan area in Kansas and Missouri. Probable charging patterns for each PHEV and the AEV are investigated for three of five daily distance categories. Overnight charging and workplace charging also are examined. The possibility for multiple charges at work is considered, as is the possibility of a charge after work, before the day's end. The degree of importance of spending a given pool of money to upgrade a residential (versus workplace) charging station is discussed. Two indicators of effectiveness of battery pack utilization are developed [a charge-depleting effectiveness factor and grid kilowatt-hours used per day per dollar of incremental vehicle expense (cost-effectiveness)], and target markets for cars used for work for each powertrain type are suggested.

AN - 1549619417; 2014-059641 AB - The Nubian Sandstone Aquifer System (NSAS) covers large territories (area: 2X10 (super 6) km (super 2) ) in four countries: Sudan (17%), Libya (34%), Chad (11%), and Egypt (38%). The NSAS comprises two interconnected major basins: the Kufra Basin in Libya, Sudan, and Chad and Dakhla Basin in Egypt. In this study, we are developing and applying an integrated cost-effective approach to understand the hydrologic setting of the NSAS and the factors (i.e., natural and/or anthropogenic) controlling it evolution. In this understanding we are trying to answer these questions: (1) is the NSAS used in a sustainable manner, or it is being depleted? (2) if the latter is true, how long could it be used and what would the optimum extraction rates be? Analysis of the Gravity Recovery and Climate Experiment (GRACE)-derived Terrestrial Water Storage (TWS) inter-annual trends over the NSAS revealed an area of significant TWS depletion (1.3+ or -0.66X10 (super 9) m (super 3) /yr) that is correlated with the Dakhla Basin in Egypt. Findings include (1) excessive groundwater extraction, not climatic changes, is responsible for the observed TWS depletion; (2) we estimate that the Dakhla Basin in Egypt, if mined at present extraction rates, could last for a period approaching 4000 years. If, instead, we were to adopt the projected rates of artificial extraction in 2070 (2.8X10 (super 9) m (super 3) /yr) and the present natural discharge rates (0.506X10 (super 9) m (super 3) /yr), it will be consumed in less than half this period (1500 years), and in an even shorter time period (350 years) if the extraction rates continue to double every 50 years; and (3) observed depletions over the Dakhla Basin and their absence across the remaining segments of the NSAS suggest that the aquifer is at near-steady conditions except for the Dakhla Basin that is witnessing unsteady transient conditions. Implications for applying the methodologies advocated for assessment and optimum management of a large suite of fossil aquifers worldwide are clear.

As a consequence of the extreme climate event, reduction of power generation, regulatory suspension of water rights and profound ecological impacts were observed due to water shortage during and thereafter the drought. To improve understanding of potential risk of decreasing water supply and energy production at Texas, an assessment of water availability and its potential impacts on power generation during drought was performed. In this impact analysis, we identified three drought scenarios based on historical drought records and projected climate from the GFDL and the PCM global climate models, for greenhouse gas emission scenarios A1B, A2, and B1 defined by the IPCC. The three drought scenarios include (1) 2011 drought conditions (the worst drought in history), with the current level of water use; (2) a single-year drought (2022) projected for the period of 2020-2030, with the assumed projected water use level for 2030; and (3) a multiple-year drought constructed with climate data for 1950-1957 and water demand projected for 2030. The projected drought scenario in 2022 and the historical droughts in 2011 and 1950-1957 represent two different precipitation patterns in the Texas-Gulf river basin. A hydrologic model was constructed for the Texas-Gulf river basin by incorporating climate and water use data corresponding to three drought scenarios, respectively, and 125 reservoirs currently supporting water withdrawal for various sectors and cooling water for power generation. The model outputs provide a base to identify vulnerable watersheds that have low water availability for the water demand required in the area and low-storage reservoirs that are at risk of providing insufficient water supply for thermoelectric cooling and other water users. The spatial distribution of the potentially vulnerable watershed and reservoirs further suggest that drought impacted areas are highly correlated with the high-population areas at the vicinity of the large metropolitan areas in Texas. The results of this impact analysis provide insights for long-term power generation planning as well as spatial water constraints on regional economic development.

With Egypt's population increasing from thirty million in the 1960's to over eighty million today and expected to rise to over 110 million by 2035, the most critical issue is quantifying the current and projected water sources for drinking supplies and agriculture. Given the inaccessible terrain and lack of adequate hydrologic monitoring networks, it is difficult to assess the hydrologic systems in Egypt and much of the Middle East and North Africa (MENA). We developed and applied an integrated approach to quantify the partitioning of precipitation into runoff, recharge, and evapo-transpiration in Egypt using hydrologic measurements extracted from satellite remote sensing. We constructed and successfully calibrated satellite-driven hydrologic models using TRMM-based precipitation, ASTER elevation, AVHRR soil moisture, and Landsat landuse and landcover data for the largest watersheds of Egypt from 1998-2013. Our earlier models were calibrated against streamflow measurements from Wadi Girafi; the calibrated parameters were then applied to ungauged basins using physical catchment descriptors. More recently, the models were further calibrated against recharge estimates extracted soil temperature probes. Climate change scenarios were performed using CO2 emission estimates from the IPCC fourth assessment report to project the change in precipitation and temperature and the subsequent impact on recharge in Egypt. First-order estimates of the average annual modern recharge for the Nubian aquifer (13.0X10 (super 6) m (super 3) /yr) and the shallow Alluvial aquifers in the Sinai Peninsula for the investigated watersheds (456X10 (super 6) m (super 3) /yr) and the shallow Alluvial aquifers in the Eastern Desert (147X10 (super 6) m (super 3) /yr) were computed using the SWAT (Soil Water Assessment Tool) model and public source global remote sensing data sets. These transferable procedures have successfully been applied to watersheds in Morocco, Turkey, and Kuwait, where preliminary estimates of the average annual recharge in the investigated watersheds are 5.2X10 (super 9) m (super 3) , 2.9X10 (super 9) m (super 3) , and 1.5X10 (super 9) m (super 3) . Results provide a clearer picture of the water resources in Egypt and the MENA region as a whole.

Water requirements to support various solar technologies - for cooling systems and/or equipment cleaning - are an important factor because of water rights and ecological water considerations in this arid region. Impacts were analyzed for the Final Programmatic Environmental Impact Statement for Solar Energy Development in Six Southwestern States, released in July 2012 by the Bureau of Land Management and the U.S. Department of Energy. As a follow-on study, groundwater modeling analyses were conducted to evaluate the drawdown associated with a range of development levels and technologies at a select set of solar energy zones. The approaches of these models ranged from one-dimensional analytical models to three-dimensional numerical models which were in some cases derived from existing federal agency modeling efforts and in other cases were newly constructed using public information. Results indicate that the impacts on water levels depend strongly on the water demand of the considered solar energy technology.

However, only recently the method became practicable for real case investigations due to significant analytical improvements [1]. In this study radioactive noble gas isotopes ( (super 81) Kr, (super 85) Kr and (super 39) Ar) were applied for the characterisation of fracture waters in the deep gold mines of the Witwatersrand Basin, South Africa [2]. Those waters catalyzed interest because of deep microbial communities that persists to depths of over 3 km [3]. The key objective of the present study is to further constrain the origin of the fluids, to determine the timing of deep subsurface life and to test the (super 81) Kr method in all kinds of environments. In contrast to expectations [4] we discovered that underground production of (super 81) Kr is a significant process in the rocks of the Withwatersrand and Ventersdorp Supergroups. All measured (super 81) Kr activities from fracture water were significantly higher than in atmospheric equilibrium. This is most likely related to elevated U/Th concentrations in the rock strata. Radiometric decay dating is complicated in such cases.

Based on the report, it was proposed that melt may be neutrally or negatively buoyant in the deep mantle. Nomura et al. [2011] attributed the iron partitioning change to a sharp high-spin to low-spin change in iron, which was found in their measurements on a Fe-diluted (5%) Mg-silicate glass at a similar pressure. However, Andrault et al. [2012] found no sharp change in iron partitioning between silicate melt and minerals in an Al-bearing system up to 120 GPa. We measured the electronic configuration of iron in two different iron-rich (20%) Mg-silicate glasses at high pressure and 300 K in the diamond-anvil cell combined with X-ray Emission Spectroscopy (XES) and Nuclear Forward Scattering (NFS): Al-free glass up to 135 GPa and Al-bearing glass up to 93 GPa. We found no sharp changes in the spin state of iron up to our maximum pressure. Instead, the population of low-spin iron increases gradually from 1 bar in both glasses, but significant population of iron still remains high spin (40-50%) even at 90-135 GPa. Our observation is consistent with the expectation of gradual response of disordered systems to compression due to the existence of diverse coordination environments for iron in the glasses and continuous structural adjustment of the disordered system with pressure. If our results on Mg-silicate glasses can provide some insights for iron in mantle melts, the spin transition in iron should be gradual and further smeared out at the high temperatures of mantle melts [Sturhahn et al., 2005], and therefore unlikely to induce a sharp change in iron partitioning in the deep mantle.

It is assumed that by restricting the competitive coordination reaction in solution it is possible to study the unperturbed sorption reaction. The adsorption of tetravalent thorium to the muscovite (001) basal plane gives a cautionary example, where the change from a weakly coordinating anion (Cl (super -) ) to a non-coordinating anion (ClO (sub 4) (super -) ) has a drastic and unexpected effect on the sorption behavior of the cation. Results from surface X-ray diffraction techniques in combination with alpha-spectrometry measurements will be presented. On the basis of these results we will demonstrate that Th(IV) exhibits a straightforward sorption behavior driven by electrostatic attraction and, to a lesser degree solution complexation and hydrolysis, when the reaction is studied in NaCl background electrolyte media . Thorium adsorbs up to a slightly higher than charge compensating coverage of 0.4 Th/A (sub UC) predominantly as an extended outer sphere complex with two intact hydration spheres. By the same method and under the same solution conditions--but with NaClO (super -) (sub 4) instead of NaCl--the adsorption behavior changes drastically: no interaction of Th with the interface can be detected under these conditions. The changes in solution chemistry are comparably minor, and it appears unlikely that changes in the complexation behavior can explain this observation. Potential interfacial reaction mechanisms underlying this unanticipated behavior will be discussed.

The Northern Circumpolar Soil Carbon Database (NCSCD) was developed to quantify stocks of soil organic carbon (SOC) in the northern circumpolar permafrost region (a total area of 18.7 X 10 (super 6) km (super 2) ). The NCSCD is a geographical information system (GIS) data set that has been constructed using harmonized regional soil classification maps together with pedon data from the northern permafrost region. Previously, the NCSCD has been used to calculate SOC storage to the reference depths 0-30 cm and 0-100 cm (based on 1778 pedons). It has been shown that soils of the northern circumpolar permafrost region also contain significant quantities of SOC in the 100-300 cm depth range, but there has been no circumpolar compilation of pedon data to quantify this deeper SOC pool and there are no spatially distributed estimates of SOC storage below 100 cm depth in this region. Here we describe the synthesis of an updated pedon data set for SOC storage (kg C m (super -2) ) in deep soils of the northern circumpolar permafrost regions, with separate data sets for the 100-200 cm (524 pedons) and 200-300 cm (356 pedons) depth ranges. These pedons have been grouped into the North American and Eurasian sectors and the mean SOC storage for different soil taxa (subdivided into Gelisols including the sub-orders Histels, Turbels, Orthels, permafrost-free Histosols, and permafrost-free mineral soil orders) has been added to the updated NCSCDv2. The updated version of the data set is freely available online in different file formats and spatial resolutions that enable spatially explicit applications in GIS mapping and terrestrial ecosystem models. While this newly compiled data set adds to our knowledge of SOC in the 100-300 cm depth range, it also reveals that large uncertainties remain. Identified data gaps include spatial coverage of deep (> 100 cm) pedons in many regions as well as the spatial extent of areas with thin soils overlying bedrock and the quantity and distribution of massive ground ice. An open access data-portal for the pedon data set and the GIS-data sets is available online at http://bolin.su.se/data/ncscd/. The NCSCDv2 data set has a digital object identifier (doi:10.5879/ECDS/00000002).

Also in the mid-1990's our group began investigating ion adsorption phenomena (primarily cations) over a wide range of temperatures extending into the hydrothermal regime (10-250 degrees C), mostly on rutile, but also on several other metal oxides[2]. More recently, we have also complimented these macroscopic data with a variety of molecular-level information, including X-ray synchotron experiments, and static DFT as well as classical molecular dynamics (MD) simulations. CD-MUSIC has proven to be a sturdy framework within which we have been able to coherently interpret this assortment of data[3,4]. This contribution will summarize our efforts to rationalize adsorption data for rutile to 250 degrees C within the CD-MUSIC model framework with particular focus on Sr (super 2+) and Zn (super 2+) . Our classical MD simulations suggest that the enhanced adsorption observed macroscopically as temperature increases is due to adsorbed cations moving closer to the surface and shedding more bulk hydration water in the process. CD-MUSIC can mimic this behavior although the agreement is not perfect, suggesting extensions to CD-MUSIC may be warranted.

One set (SCH) was gray-colored and showed extraordinary geochemical characteristics: As (6.7-11.5%), Pb (1.5-2.1%), Zn (0.1-0.2%), and pH (3.1-3.5). The other set (SCL) was brown-colored and had As (0.3-1.2%), Pb (0.02-0.22%), and Zn (0.01-0.02%) at pH of 2.5-3.1. Terminal Restriction Fragment Length Polymorphism revealed that the bacterial communities in SCL were more diverse than those in SCH. The clones identified in SCL were closely related to acidophilic bacteria within the genus of Acidobacterium (18%), Acidomicrobineae (14%), and Leptospirillum (10%). Most clones in SCH were closely related to Methylobacterium (79%) and Ralstonia (19%), both of which are well-known metal-resistant bacteria. The archaeal community in SCL was relatively simple: Thermogymnomonas (32%) and unclassified Euryachaeota (48%). No archaeal community was detected in SCH sediments. Although total As was extremely high, over 95% of it was in the form of scorodite (FeAsO (sub 4) .2H (sub 2) O), as confirmed by XAFS analysis. Water-soluble As was only approximately 208 and approximately 0.06 ppm in SCH and SCL, respectively, which is not known to be toxic to bacteria; As(V) as much as 1000-1300 ppm did not influence bacterial growth. Because As was present in an oxidized and stable form it is likely that other metals released from the sediment were responsible for the differences in microbial community structure (e.g., water soluble Zn was approximately 234 and approximately 6.8 ppm in SCH ad SCL, respectively).

Coprecipitation of Pb with ferric oxyhydroxides occurred at approximately pH 4 and for Zn at pH approximately 5, about 0.5-1.0 pH unit higher than Fe (super 3+) precipitation. Coprecipitation is more efficient than adsorption in removing Pb and Zn from aqueous solutions at similar sorbate/sorbent ratios and pH. HRTEM of the Pb-Fe and Zn-Fe coprecipitates shows a mixture of 2 to 6 nm diameter 2-line ferrihydrite spheres. The co-refinement of the Pb LIII-edge and the Fe Kedge EXAFS spectra suggested that Pb formed a solid solution in the Pb-Fe coprecipitate. Desorption experiments show that more Pb (super 2+) was released from loaded sorbents collected from adsorption experiments than from Pb to Fe coprecipitates at dilute EDTA concentrations. Desorbed Pb (super 2+) versus dissolved Fe (super 3+) data show a linear relationship for coprecipitation desorption experiments but a parabolic relationship for adsorption experiments. Based on these results, we hypothesize that Pb (super 2+) was first adsorbed onto the nanometer-sized, metastable, iron oxyhydroxide polymers of 2-line ferrihydrite with domain size of 2-3 nm. As these nano-particles assembled into larger particles, some Pb (super 2+) was trapped in the iron oxyhydroxide structure and re-arranged to form solid solutions. Our study shows that coprecipitation and adsorption experiments resulted in different Pb and Zn incorporation mechanisms, which could result in different mobility, bioavailability, and long-term stability of trace metals in the environment.

Under alkaline conditions, however, the reduction of Fe (super III) ceases to be energetically favorable and suggests that under these conditions, metal reducers must utilize alternate electron acceptors. One possible alternative is elemental sulfur (S (super 0) ), which is produced when ferric minerals react with dissolved sulfide such as that created by microbial sulfate reduction. Using geochemical modeling, we show that unlike the reduction of ferric minerals, the reduction of S (super 0) becomes more energetically favorable as pH increases. We also show experimentally that, under alkaline conditions, Shewanella oneidensis is capable of reducing S (super 0) to sulfide, which then reacts with ferric minerals to form Fe (super II) . We suggest that in slightly alkaline environments where both sulfate and Fe (super III) are available, metal-reducing bacteria may survive primarily by respiring the S (super 0) created by sulfate-reducing bacteria.

Transformation of aqueous U(VI) to U(IV) under the (bio-)reducing conditions found in many subsurface environments can decrease U solubility due to the precipitation of U(IV) dioxide (uraninite), a process that has been studied extensively for uranium remediation. However, recent evidence suggests that U(VI) reduction can produce complexed U(IV) species in the solid phase, such as U(IV)-phosphate precipitates or surface-adsorbed U(IV) atoms. The molecular speciation and the stability of non-uraninite U(IV) phases is poorly understood, even though this knowledge is essential in predicting uranium behavior at contaminated sites or in the design of nuclear waste repositories. As part of understanding uranium transformations under iron reducing conditions, we examined the reduction of U(VI) by Fe(II) in the presence of Ti(IV). Ti(IV) is commonly present in natural magnetite and has been observed in the magnetic sediment fraction at the Hanford nuclear site. Titanium-doped magnetite nanoparticles of varying Ti content (Fe (sub 3-x) Ti (sub x) O (sub 4) , 0 40 kg) has precluded its use in ice core science to date. Air was extracted on site from four 250 kg polar ice samples obtained from 5-15 m below the surface of Taylor Glacier, McMurdo Dry Valleys, Antarctica. Krypton was separated from the air and dated using Atom Trap Trace Analysis. The (super 81) Kr radiometric ages agree with independent stratigraphic dating techniques within 6 ka. (super 85) Kr analysis shows that the samples are free of modern air contamination, validating our sampling strategy and experimental methods. We show that ice from the Eemian interglacial (130-120 ka BP) can be found in abundance near the surface of Taylor Glacier. Our study paves the way for reliable radiometric dating of ancient ice in BIAs and margin sites, greatly enhancing their scientific value as archives of old ice and meteorites. As sample size requirements continue to decrease, ice core (super 81) Kr dating might be a future possibility.

Temperature-dependent elastic properties, i.e. Young's modulus and Poisson's ratio, were measured for alpha-Fe matrix, M(23)C(6) and Nb(C,N) phases in various crystallographic orientation. Significant differences in the evolution of lattice strain, peak broadening/sharpening, and void development in the alpha-Fe matrix, M(23)C(6) and Nb(C,N) precipitates revealed markedly different deformation and damage mechanisms at low and high temperature in the alloy. The strengthening effect of each type of precipitates measured by lattice strain agrees with the dislocation pile-up model at room temperature, while a different dislocation behavior was observed at 650 degree C. Void volume fraction as a function of strain measured by SAXS can be described by a classic void nucleation and growth model at room temperature but not at 650 degree C, implying a different damage process at high temperature.

Experimental results show the formation and growth of defect clusters including dislocation loops and cavities as a function of increasing atomic displacement dose. At high dose, the dislocation loop structure evolves into an extended dislocation line structure, which appears to remain stable to the high dose levels examined in this study. A high concentration of cavities was also present in the microstructure. Despite high atomic displacement doses, the specimen remained crystalline to a cumulated dose of 5 x 10(15) ions/cm(2), which is consistent with the known stability of the fluorite structure under high dose irradiation. Kinetic Monte Carlo calculations show that oxygen mobility is substantially higher in hypo-stoichiometric UO(2)/CeO(2) than hyper-stoichiometric systems. This result is consistent with the ability of irradiation damage to recover even at intermediate irradiation temperatures.

The measurements were carried out at room temperature on non-irradiated and irradiated specimens exposed to 1, 4, and 10 displacement per atom (dpa) at 40-70 degree C. The EXAFS data for Fe, Cr, Mo, and Nb K-edges were recorded, and the local structure close to the X-ray absorbing atom was determined. Irradiation caused significant reductions in peak amplitude in the Fe, Mo and Nb K-edge Fourier transformed EXAFS. The data showed a systematic decrease in coordination number of neighbor atoms with increasing irradiation dose, and the dose dependence of the coordination loss was dependent on the specific element. The measured damage around Fe sites can be correlated with the dpa value, while the loss of near neighbors around Mo saturated at ~1 dpa. The coordination in the Fe matrix was reduced less by irradiation than either the coordination of Mo in solution or Nb in carbides. It was demonstrated that EXAFS can provide a detailed, atomic level description of radiation damage in complex alloy systems.

The GGA calculations of the ground state structural and elastic properties of UN show an overall better agreement with experimental data compared to LDA or GGA + U. The melting temperature of UN (T(m)) is estimated from the calculated elastic constant, with GGA predicting T(m) = 2944 (plus-or-minus sign) 300 K, in excellent agreement with experimental data. The calculated phonon dispersions of UN agree well with the low temperature measurements. Furthermore, the thermodynamic properties of UN are studied using quasiharmonic approximation by including both lattice vibrational and thermal electronic contributions. The predicted thermodynamic properties, such as enthalpy, entropy, Gibbs energy, heat capacity and thermal expansion coefficient, agree well with experimental data. The derived thermodynamic functions of UN are useful to the thermodynamic modeling of phase stabilities in UN-based materials. This study shows that the thermal electronic energy and entropy due to U 5f electrons are important to describe the free energy of UN, due to the metallic character of UN.

While the replacement of Zr with Mo involves no significant differences in terms of neutron physics (core design), U-TRU-Mo does provide advantages. U-TRU-Mo has lower TRU migration to cladding because of its simpler phase diagram, is advantageous in safety margin due to its higher thermal conductivity and better fuel-cladding-chemical-interaction resistance. High fuel swelling data, obtained at low temperatures, available in the literature are not directly applicable to the TRU-burning advanced fast reactors. The potential high swelling can also be controlled when strong cladding and degassing are used as are adopted for typical U-Pu-Zr fuel. Results and detailed analysis are presented in this paper, indicating the benefits of U-Mo base alloy fuel in TRU-burning advanced fast reactors.

These trends have been ascribed to Soret effect, fluid exsolution, and magmatic differentiation. To understand the cause of Fe isotopic variations in silicic magmas, we measured the Mg, Fe, Zn, and U isotopic compositions of a range of migmatites, granites, and pegmatites with well-characterized petrologic and geochemical contexts. No clear positive correlation is found between the isotopic compositions of Mg, U and Fe, which rules out the process of Soret diffusion. Zinc can easily be mobilized by aqueous fluids as chloride complexes. Pegmatites and some granitic rocks with high delta (super 56) Fe values also have high delta (super 66) Zn values. However, some granites with high delta (super 56) Fe values have unfractionated delta (super 66) Zn values and were presumably poor in fluids (A-type granitoids). For these samples, iron isotopic fractionation during magma differentiation is the most likely interpretation. We used the technique of Nuclear Resonant Inelastic X-ray Spectroscopy at the Advanced Photon Source to measure the mean force constant of Fe in basalt, andesite, dacite, and rhyolite glasses. We find a sudden increase in the force constant of Fe (super 2+) from dacite to rhyolite. The b-factors derived from these force constants were used in a model of magma differentiation using Rhyolite-MELTS. The correlation between delta (super 56) Fe and SiO (sub 2) is well explained by magmatic differentiation.

As a starting point, we have developed a model using a well characterized crystalline aluminosilicate (orthoclase) that has a known structure, but possess key characteristics of waste form glass, such as compositions with multiple cations, pH dependence and formation of secondary phases in dissolution. A Kinetic Monte Carlo study based on first-principles calculations of barriers for water reactions at neutral, protonated and deprotonated sites provided information on the overall dissolution rate and rate-limiting steps. The dissolution rate far from equilibrium is compared to experiments. We have also extended this approach to multi-component glasses, where we calculated reaction energies and barriers from first-principles. Insights into the molecular-level mechanisms of glass dissolution will be used for a coarser scale modeling. This work is aimed at better understanding of the dissolution behavior and development of predictive models for dissolution rates.

Life-cycle greenhouse gas (GHG) emissions of sorghum-based ethanol need to be assessed for sorghum to play a role in meeting that requirement. Results: Multiple sorghum-based ethanol production pathways show diverse well-to-wheels (WTW) energy use and GHG emissions due to differences in energy use and fertilizer use intensity associated with sorghum growth and differences in the ethanol conversion processes. All sorghum-based ethanol pathways can achieve significant fossil energy savings. Relative to GHG emissions from conventional gasoline, grain sorghum-based ethanol can reduce WTW GHG emissions by 35% or 23%, respectively, when wet or dried distillers grains with solubles (DGS) is the co-product and fossil natural gas (FNG) is consumed as the process fuel. The reduction increased to 56% or 55%, respectively, for wet or dried DGS co-production when renewable natural gas (RNG) from anaerobic digestion of animal waste is used as the process fuel. These results do not include land-use change (LUC) GHG emissions, which we take as negligible. If LUC GHG emissions for grain sorghum ethanol as estimated by the US Environmental Protection Agency (EPA) are included (26 g CO sub(2)e/MJ), these reductions when wet DGS is co-produced decrease to 7% or 29% when FNG or RNG is used as the process fuel. Sweet sorghum-based ethanol can reduce GHG emissions by 71% or 72% without or with use of co-produced vinasse as farm fertilizer, respectively, in ethanol plants using only sugar juice to produce ethanol. If both sugar and cellulosic bagasse were used in the future for ethanol production, an ethanol plant with a combined heat and power (CHP) system that supplies all process energy can achieve a GHG emission reduction of 70% or 72%, respectively, without or with vinasse fertigation. Forage sorghum-based ethanol can achieve a 49% WTW GHG emission reduction when ethanol plants meet process energy demands with CHP. In the case of forage sorghum and an integrated sweet sorghum pathway, the use of a portion of feedstock to fuel CHP systems significantly reduces fossil fuel consumption and GHG emissions. Conclusions: This study provides new insight into life-cycle energy use and GHG emissions of multiple sorghum-based ethanol production pathways in the US. Our results show that adding sorghum feedstocks to the existing options for ethanol production could help in meeting the requirements for volumes of renewable, advanced and cellulosic bioethanol production in the US required by the EPA's Renewable Fuel Standard program.

Herein we examine 8,786 bacterial and 8,166 archaeal 16S rRNA gene sequences from an array of monitoring wells in the Mahomet aquifer of east-central Illinois. Using multivariate statistical analyses we provide a comparative analysis of the relationship between groundwater chemistry and the microbial communities attached to aquifer sediment along with those suspended in groundwater. Results: Statistical analyses of 16S rRNA gene sequences showed a clear distinction between attached and suspended communities; with iron-reducing bacteria far more abundant in attached samples than suspended, while archaeal clones related to groups associated with anaerobic methane oxidation and deep subsurface gold mines (ANME-2D and SAGMEG-1, respectively) distinguished the suspended community from the attached. Within the attached bacterial community, cloned sequences most closely related to the sulfate-reducing Desulfobacter and Desulfobulbus genera represented 20% of the bacterial community in wells where the concentration of sulfate in groundwater was high (> 0.2 mM), compared to only 3% in wells with less sulfate. Sequences related to the genus Geobacter, a genus containing ferric-iron reducers, were of nearly equal abundance (15%) to the sulfate reducers under high sulfate conditions, however their relative abundance increased to 34% when sulfate concentrations were 0.2 mM sulfate. In the suspended fraction of wells where the concentration of sulfate was between 0.03 and 0.2 mM, the archaeal community was dominated by sequences most closely related to the ANME-2D, a group of archaea known for anaerobically oxidizing methane. Based on available energy (...G sub(A)) estimations, results varied little for both sulfate reduction and methanogenesis throughout all wells studied, but could favor anaerobic oxidation of methane (AOM) in wells containing minimal sulfate and dihydrogen, suggesting AOM coupled with H sub(2)-oxidizing organisms such as sulfate or iron reducers could be an important pathway occurring in the Mahomet aquifer. Conclusions: Overall, the results show several distinct factors control the composition of microbial communities in the Mahomet aquifer. Bacteria that respire insoluble substrates such as iron oxides, i.e. Geobacter, comprise a greater abundance of the attached community than the suspended regardless of groundwater chemistry. Differences in community structure driven by the concentration of sulfate point to a clear link between the availability of substrate and the abundance of certain functional groups, particularly iron reducers, sulfate reducers, methanogens, and methanotrophs. Integrating both geochemical and microbiological observations suggest that the relationships between these functional groups could be driven in part by mutualism, especially between ferric-iron and sulfate reducers.

Estimates of LUC GHG emissions focus mainly on corn ethanol and vary widely. Increasing the understanding of LUC GHG impacts associated with both corn and cellulosic ethanol will inform the on-going debate concerning their magnitudes and sources of variability. Results: In our study, we estimate LUC GHG emissions for ethanol from four feedstocks: corn, corn stover, switchgrass, and miscanthus. We use new computable general equilibrium (CGE) results for worldwide LUC. U.S. domestic carbon emission factors are from state-level modelling with a surrogate CENTURY model and U.S. Forest Service data. This paper investigates the effect of several key domestic lands carbon content modelling parameters on LUC GHG emissions. International carbon emission factors are from the Woods Hole Research Center. LUC GHG emissions are calculated from these LUCs and carbon content data with Argonne National Laboratory's Carbon Calculator for Land Use Change from Biofuels Production (CCLUB) model. Our results indicate that miscanthus and corn ethanol have the lowest (-10 g CO sub(2)e/MJ) and highest (7.6 g CO sub(2)e/MJ) LUC GHG emissions under base case modelling assumptions. The results for corn ethanol are lower than corresponding results from previous studies. Switchgrass ethanol base case results (2.8 g CO sub(2)e/MJ) were the most influenced by assumptions regarding converted forestlands and the fate of carbon in harvested wood products. They are greater than miscanthus LUC GHG emissions because switchgrass is a lower-yielding crop. Finally, LUC GHG emissions for corn stover are essentially negligible and insensitive to changes in model assumptions. Conclusions: This research provides new insight into the influence of key carbon content modelling variables on LUC GHG emissions associated with the four bioethanol pathways we examined. Our results indicate that LUC GHG emissions may have a smaller contribution to the overall biofuel life cycle than previously thought. Additionally, they highlight the need for future advances in LUC GHG emissions estimation including improvements to CGE models and aboveground and belowground carbon content data.

In this study, porous carbon-supported MnO sub(2) nanorods synthesized at room temperature were explored as an electrocatalyst for rechargeable Li-O sub(2) cells. Both high-energy X-ray diffraction and X-ray absorption fine-structure analyses showed that the prepared MnO sub(2) exhibited a tetragonal crystal structure ( alpha -MnO sub(2)), which has proved to be one of the most efficient catalysts to facilitate the charging of the Li-O sub(2) cell. Under the current synthetic approach, alpha -MnO sub(2) was uniformly distributed onto the surface of a carbon support, without disrupting the porous structure at the surface of the carbon cathode. As a result, the as-prepared catalysts demonstrated good electrochemical behavior, with a capacity of similar to 1400 mA h g super(-1) (carbon + electrocatalyst) under a current density of 100 mA g super(-1) (carbon + electrocatalyst) during the initial discharge. The charge potential was significantly reduced, to 3.5-3.7 V, compared with most of the reported data, which are above 4.0 V. The mechanism of the capacity fade with cycling was also investigated by analyzing the cathode at different states of discharge-charge by X-ray photoelectron spectroscopy.

Hydrothermal liquefaction (HTL) produces more oil from algae than lipid extraction (LE) does because protein and carbohydrates are converted, in part, to oil. Since nitrogen in the algae biomass is incorporated into the HTL oil, and since lipid extracted algae for generating heat and electricity are not co-produced by HTL, there are questions regarding implications for emissions and energy use. We studied the HTL and LE pathways for renewable diesel (RD) production by modeling all essential operations from nutrient manufacturing through fuel use. Our objective was to identify the key relationships affecting HTL energy consumption and emissions. LE, with identical upstream growth model and consistent hydroprocessing model, served as reference. HTL used 1.8 fold less algae than did LE but required 5.2 times more ammonia when nitrogen incorporated in the HTL oil was treated as lost. HTL RD had life cycle emissions of 31,000 gCO sub(2) equivalent (gCO sub(2)e) compared to 21,500 gCO sub(2)e for LE based RD per million BTU of RD produced. Greenhouse gas (GHG) emissions increased when yields exceeded 0.4 g HTL oil/g algae because insufficient carbon was left for biogas generation. Key variables in the analysis were the HTL oil yield, the hydrogen demand during upgrading, and the nitrogen content of the HTL oil. Future work requires better data for upgrading renewable oils to RD and requires consideration of nitrogen recycling during upgrading.

implications for Ag as a novel paleoproductivity proxy AN - 1648909013; 2015-010493 AB - Silver (Ag) has potential for use as a paleoproductivity proxy in environments where a high flux of organic matter creates reducing conditions in sediments. Its proposed sequestration under reducing conditions as the species Ag2S confers an advantage over the more conventional productivity proxy barite, which becomes unreliable when sulfate reduction occurs in sediments. Other conventional productivity proxies (organic carbon and biogenic silica) are subject to rapid remineralization during early diagenesis, whereas Ag is likely to be preserved. Prior studies have hinted that Ag may be delivered to sediments via diatom debris. However, whether Ag is primarily associated with the frustule silica matrix or with diatom organic matter has not been established, and hence the mechanism of Ag delivery to sediments remains ambiguous. In this study we investigated the location of Ag storage in diatoms using synchrotron micro-XRF to map Ag, along with Ca, P, S, Si, and Fe, in single cells of the coastal marine diatom Thalassiosira pseudonana. Diatoms were cultured in the laboratory with Ag added to the growth medium at 50 and 100 ppb. Samples were analyzed at the sub-micron scale at the Advanced Photon Source, Argonne National Laboratory. Detectable Ag concentrations appear to be localized to intracellular "hotspots" that are not associated with frustule Si, either as part of the matrix or surface-adsorbed. Silver "hotspots" are co-localized with Fe, suggesting that Ag is stored within vacuoles, as recently shown for Fe in centric diatoms. Overall, our results support the hypothesis that Ag is delivered to sediments with diatom organic matter and suggest a common strategy by centric diatoms for intracellular sequestration of micronutrient (Fe) and nonessential (Ag) trace metals.

Preferred variant selection and orientation memory under the influence of deviatoric stress are the 'fingerprints' of the transformation mechanism, driving force, and microstructure. For the alpha -epsilon transition in iron - significant to the structure and anisotropy of the Earth's inner core - these have been studied primarily by texture analysis of polycrystalline powders; the convoluted nature of these data, however, render it essentially impossible to examine variant selection, and even precise orientation relationships themselves. Recently developed X-ray diffraction techniques have made it possible to answer these questions. Results from two measurements are presented. First, heterogeneous variant selection was observed and the specific alpha /epsilon orientation relationship was determined under quasi-static loading using High Energy Diffraction Microscopy at beamline 1-ID of APS-ANL. Second, the spatial heterogeneity and mutual exclusivity among epsilon variants was observed at the incipient transition using the Laue mu -diffraction technique at beamline 12.3.2. of ALS-LBNL. In both cases, a 60X25mu m single crystal of iron was pressurized in a DAC and measured before and after the alpha -epsilon transition at 13GPa. In the HEDM experiment, spatial resolution is sacrificed for domain-averaged orientation and strain resoltuion, making it possible to quantify the magnitude of the applied deviatoric stress in situ. In the Laue mu -Diffraction technique, the local lattice orientations are mapped with 1mu m resolution, displaying marked spatial variation. These pilot experiments open new possibilities for investigating high pressure/high temperature transformations in situ. By mapping both orientations and lattice strains, the nature of the mechanisms and driving forces can be illuminated.

Over the past few years a variety of new highly refractory minerals which are early condensates have been discovered in meteorites. These phases pose extreme difficulties for rigorous structure analysis because they occur usually in few individual crystals of 1 - 3 micron diameter. The same problems hold for high pressure phases occurring in melt veins in S5-6 level shocked meteorites. We have examined the structure of early condensates and minerals in shock melt veins using synchrotron based micro-Laue-, micro-monochormatic diffraction and EBSD.

Precise measurements of crystallographic information of (Mg,Fe)SiO3 at the pressure (P) and temperature (T) conditions within Earth's lower mantle are therefore critical for interpreting seismic observations. X-ray single-crystal structural analysis provides the most unambiguous information for characterizing phases of interest. However, the structures of perovskite (Pv) above approximately 90 GPa and the post-perovskite (PPv) phases cannot be recovered back to ambient conditions. Consequently, studies of the high pressure phases in (Mg,Fe)SiO3 are restricted to polycrystalline samples within a diamond anvil cell (DAC) device. Our goal is to in-situ indentify crystal orientations of individual grains and then apply conventional single-crystal structural analysis to the individual grains. The first and most important step is to grow relatively large grains.. The crystal sizes of individual grains were determined to be within 500 nm X 500 nm by a two-dimension scan using the 300 X 500 nm2 X-ray beam at 34 ID-E of APS. The second step is to collect the single crystal diffraction data while the sample sits at the orientation center of the omega (omega ) rotation stage. Once the orientation matrix is determined, the diffraction spots can be assigned to the grain of origin and peak intensities can be evaluated for the structural refinement. A total of 130 grains belonging to the Pv phase were indexed with up to 48 reflections for each grain and all of them can be assigned to the known Pbnm space group. Similarly, up to 54 reflections for each grain of the PPv phase can be assigned to the Cmcm space group. Up to four equivalent reflections were indentified for both of the orthorhombic symmetries. Figure 1 shows four symmetric equivalent reflections for the {121} of the Pv phase and three reflections for the {223} of the PPv phase. To our knowledge, this is the first report on in-situ single-crystal structural analysis for both the Pv and PPv phases in (Mg,Fe)SiO3 at deep lower mantle P-T conditions.

Both types of filters suffer from the problem of generating extreme outliers in the ensembles produced in a nonlinear system. This is especially true for the deterministic filter with a large ensemble size. The outliers can persist for a long time, generate substantial separation from the other ensemble members, and contribute to large errors in the ensemble mean analysis. To address the problem of extreme outliers, a new technique is developed that randomly divides the full ensemble into sub-ensembles of equal size for each observation at each analysis step. All sub-ensembles are updated independently using deterministic filter algebra. The random subgrouping technique removes the effects of extreme outliers in two ways: the smaller ensemble size for each sub-ensemble limits the deviation of an outlier from the ensemble mean and the random subgrouping prevents the long-term persistence of an outlier. Test results, using the random subgrouping technique on two low-order models (Lorenz-63 and Lorenz-96) and a global QG atmospheric model coupled to a slab ocean, show that the new scheme significantly improves performance compared to regular stochastic and deterministic filters.

Fundamental knowledge of the kinetics of these processes is based primarily on experimental observations of reactions at faces of single crystals or macroscopic data from pure mineral powder suspensions. Sorption reactions at crystal faces are generally very fast, on the order of microseconds or less, with reaction times often limited only by film diffusion at the mineral-water interface. In well-stirred suspensions of aquifer sediments, however, sorptive equilibrium can take many hours or days to achieve steady-state concentrations. We have examined the potential reasons for sorption rate limitation using uranium(VI) sorption by sediments from a sandy aquifer in Savannah River, South Carolina (USA). U(VI) sorption by sand-sized grains from the aquifer is dominated by reaction with secondary mineral coatings on quartz and feldspar grains. The coatings studied were on the order of 15 microns in thickness (i.e., from quartz grain to aqueous solution) and composed primarily of clay minerals and hematite of varying particle size. Microfocused-XRF imaging of elemental concentrations (e.g., U, Fe) of polished cross-sections of the grain/coating contact showed strong spatial correlations of U and Fe within the coatings, regardless of the length of reaction time (30 minutes to 4 weeks). The spatial resolution of the mu -XRF technique is of the order of 2 microns in horizontal directions, but the uncertainty of the observed spatial gradients is high due to grain curvature away from the polished surface and fluorescence contributed from the entire 30 micron thickness of a typical grain/epoxy thin section. TEM characterization of focused-ion-beam (FIB), vertically-extracted samples of the grain-coating contact shows that complex pore networks exist within the coatings of variable dimensions and unknown connectivity. Using scanning TEM (STEM) tomography, it can be seen that there are large numbers of pore throat sizes less than 10 nm within the coatings. We hypothesize that diffusion through these pores, which likely have electrically charged surfaces, controls the observed macroscopic rates of U(VI) sorption in batch experiments with sand grains. Evidence to support this hypothesis was observed by studying U and Fe fluorescence spatial variation within FIB samples (1 micron thick) at 200 nm spatial resolution. With this greater spatial resolution, it is possible to see U concentration variations within the coatings that are dependent on the time of sorption reaction, and illustrates how the coating environment constitutes a diffusion constraint to achieve adsorptive equilibrium between an aqueous phase and the mineral surfaces. Including this diffusion constraint within conceptual models for reactive contaminant transport may be significant at the field scale, because secondary mineral coatings are potentially both sinks and sources of contaminants depending on the history of a contaminated site. This is important in resolving long-term transport predictions at DOE sites, such as Hanford and Savannah River, where equilibrium versus kinetic reactive transport models are being evaluated.

Drought indices (meteorological, agricultural and hydrological) define departures from normal conditions and are used as proxies for monitoring water availability. Many of these indices exclude significant controlling factor(s), do not work well in specific settings and regions, and often require long (> or =50 yr) calibration time periods and substantial meteorological data, limiting their application in areas lacking adequate observational networks. Additional uncertainties are introduced by the models used in computing model-dependent indices. Aside from these uncertainties, none of these indices measure the variability in terrestrial water storage (TWS), a term that refers to the total vertically integrated water content in an area regardless of the reservoir in which it resides. Inter-annual trends in TWS were extracted from monthly Gravity Recovery and Climate Experiment (GRACE) data acquired (04/2002 to 08/2011) over Africa and correlated (in a GIS environment) with relevant temporal remote sensing, geologic, hydrologic, climatic, and topographic datasets. Findings include the following: (1) large sectors of Africa are undergoing statistically significant variations (+36 mm/yr to -16 mm/yr) due to natural and man-made causes; (2) warming of the tropical Atlantic ocean apparently intensified Atlantic monsoons and increased precipitation and TWS over western and central Africa's coastal plains, proximal mountainous source areas, and inland areas as far as central Chad; (3) warming in the central Indian Ocean decreased precipitation and TWS over eastern and southern Africa; (4) the high frequency of negative phases of the North Atlantic Oscillation (NAO) increased precipitation and TWS over northwest Africa; (5) deforestation in the Congo Basin and southern Tanzania decreased TWS and (6) the construction of dams (e.g., Merowe High Dam, Tekeze, Amerti-Neshi, Beles, Gilgel Gibe I, Gilgel Gibe II, and Karadobi) throughout the GRACE period increased TWS in upstream Nile Valley countries. Given the 10-year monthly GRACE record of water availability data (represented by GRACE TWS) acquired on the sub-basin scale across the globe, and the plans underway for deployment of a GRACE follow-up (2016-2026), consideration should be given to using GRACE TWS data as an alternative, viable drought index, and for monitoring the impacts of human interventions on hydrologic systems.

Groundwater age is an important parameter that integrates aquifer recharge and flow dynamics and provides the ability to reliably constrain groundwater models. We have used multiple isotope tracers (C-14, He-4, and Kr-81) to estimate the age of groundwater along a 400-km transect in the north-eastern part of the Guarani Aquifer System (GAS) in Brazil. Carbon-14 measurements were made with an AMS, He-4 by mass-spectrometry, and Kr-81 by atom trap trace analysis (ATTA). Groundwater samples were collected along a groundwater flow path that runs from the outcrop area in the east to the deep confined section in the west, where the aquifer is up to about 1000 m deep. Present groundwater recharge occurs in the outcrop areas, as indicated by the presence of tritium and modern 14C. Carbon-14 activities reach values below detection limit at relatively short distances (a few km) from the outcrop. Abundance of 81Kr (half-life 229 Ka), in samples free of C-14, decreases from 0.81+ or -0.11 (expressed as (81Kr/Kr)sample/(81Kr/Kr)air) in the east to 0.18+ or -0.03 in the western-most sample (estimated age=566+ or -60 ka). Measured 4He-excess is far above that expected from in-situ production rates in sandstone aquifers and overestimates the age by several orders of magnitude. We used 81Kr ages to calibrate the 4He geochronometer which indicates a basal flux of about 2.8X10-11 cm3 STP He/cm2/a. This flux is lower than most estimates of basal flux in previous studies and will allow a wider use of 4He for groundwater dating and aquifer characterization.

We have investigated how the surface roughness and capillary potential Pc influences the thickness of a KCsI2 brine film on different minerals (silica and mica) under confinement with supercritical (sc) CO2. The thicknesses of brine films coating interior surfaces of mineral windows in a high-pressure cell were determined through synchrotron X-ray fluorescence of iodide ion at 7.8 MPa and 40 degrees C (representative of conditions at about 0.75 km below the land surface), with scCO2 as the immiscible confining fluid. The area-averaged film thicknesses on both silica and mica windows measured within a narrow Pc range from 0.18 to 3.7 kPa were found to be strongly controlled by surface roughness. The film thickness dependence on Pc was moderate (decreased 25% to 50%) on mica surfaces, and minor (decreased about 6% to 25%) on silica. We observed thicker brine films on mica, than on silica. The area-averaged film thicknesses on the 330 nm root mean square roughness (Rrms) silica surface ranged from 265 nm to 249 nm over the applied Pc range. The film thicknesses on the 146 nm Rrms mica surface ranged from 505 nm to 402 nm over the same range of Pc. The film thickness-Pc relation was obtained for the drainage and rewetting process on both minerals. Film thicknesses on the smoother mica surfaces were similar to DLVO-predicted values, while measurements on the smooth silica were only about 25% of the predicted thicknesses. The thickness-Pc relation of silica was nonhysteretic. But measurements on mica showed clear hysteresis, apparently indicative of changes in wettability during the drainage and rewetting process. Further experimental and computational studies on brine films wetting mineral surfaces over wider ranges of capillary pressures are needed in order to better understand film behavior under geologic CO2 sequestration conditions.

Periodic adjustments in river stage changes temporal and spatial patterns in hydraulic pressure, initiates propagation of lateral and vertical hyporheic flux, and affects the riparian ecological system by changing the hyporheic penetration distance, hyporheic flux rate, and thermal conditions in river banks. While this issue has been largely neglected by watershed scientists and managers, there is the potential to use hyporheic metrics in setting dam release rules and restoring downstream river reaches. In order to evaluate the hyporheic feedbacks of various dam release patterns, this study applied a computational fluid dynamics (CFD) model to simulate the interaction of open water hydrographs on porous media lateral hyporheic exchange for the Green River, Utah, downstream of Flaming Gorge Dam. The CFD initially represented the river as a straight channel with a thick porous media extending from the channel banks and bottom. The dam release hydrographs changed the patterns of hyporheic flux at the river banks, the penetration distance of the hyporheic flux, the subsurface thermal patterns, and the residence time of water in the subsurface. The results suggest the undulating river stage downstream of dam releases can initiate patterns of hyporheic exchange similar to those induced by restoration of river bed morphology.

As a bottleneck of many high-resolution studies, robust and efficient Stokes solvers are needed. These methods are necessarily multilevel and require accurate coarse representations of operators. The problems arising in lithosphere dynamics are challenging for standard methods due to multiscale structures creating long-range interaction through thin structures that are difficult to accurately represent using in coarse spaces. We incorporate aspects of multigrid, domain decomposition, and multiscale finite element methods to adaptively construct coarse spaces that allow rapid coarsening in smooth regions without sacrificing accuracy in heterogeneous regions. These methods have the additional benefit of working with highly parallel smoothers that can also be used for nonlinear problems.

To develop a quantitative understanding of iron isotopic fractionation at high temperature, it is critical to establish equilibrium isotopic fractionation factors between Fe (super 2+) and Fe (super 3+) in minerals and melts. The reduced partition function ratio (beta -factor) controlling equilibrium isotopic fractionation can be derived from Nuclear Resonant Inelastic X-ray Scattering (NRIXS) measurements at a synchrotron facility. For the (super 56) Fe/ (super 54) Fe ratio at high temperature, we simply have 1,000 Xln beta =2,904/T (super 2) with the average force constant of the bonds holding iron in position (in N/m), which is calculated by taking the 3rd moment of the NRIXS scattering probability function (Dauphas et al. 2012). We have measured the force constants of olivine and silicate glasses of basalt, andesite, dacite, and rhyolite compositions synthesized under controlled redox conditions. XANES and conventional Moessbauer measurements were also performed on the same glasses to characterize the Fe (super 3+) /Fe (sub tot) ratio and coordination environment of iron. In basalt, andesite, and dacite, we find that increases with the Fe (super 3+) /Fe (sub tot) ratio. Extrapolation to pure Fe (super 2+) and Fe (super 3+) gives equilibrium isotopic fractionation between these two redox states of nearly equal +0.2 to +0.3 ppm at magmatic temperatures ( nearly equal 1,300 degrees C). For comparison, the precision of stable iron isotope analyses by MC-ICPMS is nearly equal + or -0.03 ppm, so redox state can influence the iron isotopic composition of magmatic rocks. However, this fractionation is insufficient to explain the heavy iron isotopic composition of MORBs and we are currently investigating whether pressure or other parameters can influence iron beta -factor in magmas. We have also found that the force constant of Fe (super 2+) in rhyolitic melt is high, which explains the heavy Fe isotopic compositions of some granitoids. Dauphas N. et al. 2009. Earth Planet. Sci.

We are investigating thresholds of bed mobility, dynamic hyporheic storage during floods, and effects on biogeochemical reactions in streams. We investigated hydrogeomorphology in several streams prior to, during, and after a flood. Fine particles were readily deposited onto the bed during baseflow but penetrated more shallowly in hyporheic flow compared with solutes due to the high rate of filtration of fine particles. Due to shallower storage in the bed, fine particles were rapidly entrained during the rising limb of the flood hydrograph. In contrast, solutes were transported deeper and stored longer in hyporheic flow paths during baseflow. Rather than being flushed by the flood, we observed that solutes were stored longer due to expansion of hyporheic flow paths beneath the temporarily enlarged bedforms during the flood. Three important timescales determined the fate of solutes and fine particles: (1) flood duration, (2) relaxation time of flood-enlarged bedforms back to former dimensions, and (3) resulting adjustments and lag times of hyporheic flow. These interactions explain why we observed a peak accumulation of natural particulate organic matter between 2 and 4 cm deep in the bed, i.e., below the scour layer of mobile bedforms but above the maximum depth of particle penetration with hyporheic flow. Thus, physical interactions between bed mobility and hyporheic transport influence how organic matter is stored in the bed and how long it is retained, which affects decomposition rate and metabolism of this southeastern Coastal Plain stream. In a related study of mixed cobble-gravel-sand bed in the Iowa River, IA we measured and modeled hydraulic transport and stream metabolism to determine thresholds of bed shear stress that disrupt stream metabolism. Floods over a four-year period were classified in two disturbance categories based on a critical Shields stress for sand and gravel-bed rivers. Floods not exceeding the critical Shields stress entrained only fine particles from the bed which depressed stream metabolism for 5 days or less due to turbidity effects. Floods exceeding the critical Shields stress depressed stream metabolism for greater than 15 days due to periphyton being dislodged from a fully mobilized bed. Dynamic interactions between hyporheic flow, bed mobility, and flow variation had strong but differential influences on in-stream retention of solutes and fine particulates. These hydrogeomorphic relationships have implications for microbial respiration of organic matter, carbon and nutrient cycling, and fate of contaminants in streams.

Iron oxide nanoparticles can act as sinks and/or carriers for heavy metal contaminants; therefore, it is important to develop a better understanding of factors affecting their formation. Organic coatings are ubiquitous in aqueous environments where they can exist on mineral surfaces (e.g., biofilm), as nanoparticle surface coatings (e.g., natural organic matter), or be introduced as coagulants in water treatment systems. These surface coatings could influence the formation of iron oxide nanoparticles and thus, the mobility of aqueous contaminants. Therefore, to better understand the fate and transport of contaminants in complex aqueous environments, we need more accurate information about mechanisms governing heterogeneous and homogeneous nucleation and growth of iron(III) hydroxide nanoparticles in the presence of organic surface coatings. In this work, we used a unique measurement technique allowing for simultaneous small-angle X-ray scattering (SAXS) and grazing incidence (GISAXS) analysis to monitor nanoparticle nucleation in solution and at substrate surfaces. Clean quartz, and polyaspartate- and alginate-coated substrates were chosen as model substrates to represent mineral coatings, engineered organic coatings and natural organic coatings. Polyaspartate was determined to be the most negatively charged substrate and quartz to be the least negatively charged substrate; however, after 2 h of reaction, the total nanoparticle volume calculations--determined from GISAXS--indicate that precipitation of positively-charged iron(III) hydroxide nanoparticles is 10 times higher on the quartz substrate than on the polyaspartate substrate. This implies that electrostatics do not govern iron(III) hydroxide nucleation. Furthermore, homogeneous nucleation approximately 250 mu m above the substrate surface was highest in the presence of the polyaspartate substrate and least in the presence of the quartz substrate. Based on contact angle measurements and surface characterization, we concluded that the degree of hydrophilicity may control heterogeneous nucleation. Differences in substrate surface energy and potential arrangements of functional groups at the substrate surface (-OH and -COOH) may also contribute to the observed trends. These results provide new information for elucidating the effects of polymeric organic substrate coatings on the size, volume, and location of nucleating iron hydroxides, which will help predict nanoparticle interactions in natural and engineered systems. While iron oxide nanoparticles have been extensively studied in aqueous systems, there are still few studies providing in situ hetero- and homogeneous nucleation in the presence of relevant environmental organic substrates, which can aid in modeling the fate and transport of nanoparticles and contaminants in aqueous systems.

These ultra-low velocity zones (ULVZs) have been interpreted as aggregates of partially molten material (e.g. Williams and Garnero 1996, Hernlund and Jellinek, 2010) or as solid, iron-enriched residues (e.g. Knittle and Jeanloz, 1991; Mao et al., 2006; Wicks et al., 2010), typically based on proposed sources of velocity reduction. The stabilities of these structure types have been explored through dynamic models that have assembled a relationship between ULVZ stability and density (Hernlund and Tackley, 2007; Bower et al., 2010). Now, to constrain the chemistry of ULVZs, more information is needed on the relationship between density and sound velocity of candidate phases. Recently, we have shown that the characteristically low sound speeds of ULVZs can be produced by small amounts of iron-rich (Mg,Fe)O, which is likely to be found in iron-rich assemblages based on current partitioning studies (eg. Sakai et al., 2010; Tange et al., 2009). We determined the Debye velocity (V (sub D) ) of (Mg (sub .16) (super 57) Fe (sub .84) )O using nuclear resonant inelastic x-ray scattering (NRIXS), and calculated the seismically relevant compressional (V (sub P) ) and shear (V (sub S) ) wave velocities up to 120 GPa using an equation of state of a similar composition (Wicks et al., 2010). These densities and sound velocities, in turn, are consistent with reasonable morphologies of modeled solid ULVZs (Bower et al., 2011). To increase the accuracy of density and sound velocity predictions, measurements must be made at elevated temperatures to correctly predict the properties of iron-rich (Mg,Fe)O at mantle conditions. In this study, we present the pressure-volume-temperature equation of state of (Mg (sub .06) (super 57) Fe (sub .94) )O measured up to pressures of 120 GPa and temperatures of 2000 K. Volume was measured with x-ray diffraction at beamline 13-ID-D of the Advanced Photon Source, where high pressures and temperatures are achieved in a diamond anvil cell with in-situ laser heating. The sample was mixed with Fe metal buffer/pressure standard with a neon pressure medium, with salt plates on either side as thermal insulator. We will discuss these density measurements and their impact on sound velocities of iron-rich (Mg,Fe)O in the context of a solid ULVZ.

Magnesium-silicate perovskite is the dominant mineral of the Earth's lower mantle. The composition of perovskite in the mantle is likely dominated by the MgSiO3 component but it also contains small but nearly equal amounts of Al and Fe. It is likely that the Fe content of magnesium-silicate perovskite varies in the lower mantle as a result of the effect of pressure on the partitioning of Fe between magnesium-silicate perovskite and coexisting ferropericlase and possibly due to the presence of chemical heterogeneities that may arise either from subduction of oceanic crust or the presence of primordial material. In order to interpret one dimensional seismic velocity profiles for the lower mantle it is crucial not only to determine velocities for the major minerals such as magnesium-silicate perovskite but also to assess the effect of major chemical substitutions on the elasticity. Using ultrasonic interferometry in the multianvil we measured densities and P and S velocities of monomineralic hot-pressed powdered samples of magnesium silicate perovskite at conditions encompassing the upper region of Earth's lower mantle. We examined these properties for the MgSiO3 end member perovskite plus samples of the same phase containing Fe and Fe and Al. These measurements were performed at the APS synchrotron x-ray source to enable pressure and sample length measurements and were performed up to 25 GPa and 1200 K. The results allow models for seismic wave velocities in the lower mantle to be tested against seismic models and for variations in velocity in the lower mantle to be understood in terms of temperature and composition.

The study of electronic and magnetic properties of iron oxides under high pressure is essential to enhance our knowledge of these materials and the geophysical phenomena they are involved in. Here, we report the results of Synchrotron Mossbauer Spectroscopy (SMS) in the forward scattering geometry to determine the nuclear hyperfine field parameters of Fe-ions in the recently discovered iron oxide - Fe (sub 4) O (sub 5) . Fe (sub 4) O (sub 5) - synthesized at high pressure and temperature - is stable in the pressure range 5 - 30 GPa and is recoverable in ambient conditions (super 1) . Fe (sub 4) O (sub 5) crystallizes in the orthorhombic Cmcm structure and the Fe atoms occupy three non-equivalent sites at 4a, 8f and 4c Wyckoff positions. 57Fe SMS spectra were collected at several different pressures in the range 0 - 33 GPa. The SMS spectra were fitted using two sites for pressures upto 18 GPa and a single site above 18 GPa. The magnetic properties and electronic environment of the iron sites deduced from the refined hyperfine parameters as a function of pressure will be discussed and compared with the results of standard Mossbauer spectroscopy.

High-pressure studies of iron bearing spinels attract extensive attention in order to understand strong electronic correlation such as the charge transfer, electron hopping, electron high-low spin transition, Jahn-Teller distortion and charge disproponation in the lower mantle or subduction zone [1]. Experiment Structure transitions of Fe3-xSixO4, Fe3-xTixO4 Fe3-xCrxO4 spinel solid solution have been investigated at high pressure up to 60 GPa by single crystal and powder diffraction studies using synchrotron radiation with diamond anvil cell. X-ray emission experiment (XES) at high pressure proved the spin transition of Fe-Kbeta from high spin (HS) to intermediate spin state (IS) or low spin state (LS). Mossbauer experiment and Raman spectra study have been also conducted for deformation analysis of Fe site and confirmation of the configuration change of Fe atoms. Jahn-Teller effect A cubic-to-tetragonal transition under pressure was induced by Jahn-Teller effect of IVFe2+ (3d6) in the tetrahedral site of Fe2TiO4 and FeCr2O4, providing the transformation from 43m (Td) to 42m (D2d). Tetragonal phase is formed by the degeneracy of e orbital of Fe2+ ion. Their c/a ratios are c/a<1 due to dx2-y2 orbital of the electronic tetrahedral configuration. However, Fe3O4 (I), Fe2SiO4 (N), do not have a tetragonal polymorph because of no IVFe2+ ion [2]. Spin transition HS-to-LS transition starts from 15.6 GPa in Fe3O4, 19.6 GPa in Fe2TiO4, 17GPa in Fe2SiO4. The transition is more capable due to VIFe2+ in the octahedral site. The extremely shortened octahedral bonds result in a distortion of 8-fold cation site. This structure change is accelerated by HS-LS transition of Fe2+ in the 8-fold coordination site. Post spinel transition The transition to orthorhombic post-spinel structure with Cmcm has been confirmed in the whole compositional range of Fe3-xTixO4 and Fe3-xCrxO4 . There are M1 and M2 in the orthorhombic phase. Fe2+ and Ti4+ are disordered in the M2 site. At pressures above 53 GPa, Fe2TiO4 structure further transforms to Pmma. This structure change results in the order-disorder transition [2]. New structure of Fe2SiO4 The spin transition exerts an influence to Fe2SiO4 spinel structure and triggers two distinct curves of the lattice constant in the spinel phase. The reversible structure transition from cubic to pseudo-rhombohedral phase was observed at about 45 GPa. This transition is induced by the 20% shrinkage of ionic radius of VIFe2+at the low sin state. Laser heating experiment at 1500 K has confirmed the decomposition from the pseudo-rhombohedral phase to two oxides of FeO and SiO2.

While investigating the stability and decomposition products of siderite (FeCO (sub 3) ) at conditions of the Earth's mantle we obtained, at 10 GPa and about 1800 K, a single crystal of unknown phase. High pressure and temperatures were achieved using a laser heated diamond anvil cell. Diffraction data were obtained using highly focused synchrotron x-rays. Structural solution and refinement of the single crystal diffraction pattern indicate that the phase is a new compound with formula Fe (sub 4) O (sub 5) . The phase has orthorhombic symmetry where iron is 6-coordinated in layers of trigonal prisms and edge-sharing octahedra. First-principle calculations show that Fe (sub 4) O (sub 5) is stable at high pressure with respect to its possible breakdown products (FeO and Fe (sub 3) O (sub 4) in the cubic and orthorhombic structures). We performed several HP-HT syntheses starting from mixtures of pure Fe+Fe (sub 3) O (sub 4) and Fe+Fe (sub 2) O (sub 3) in appropriate proportions. Fe (sub 4) O (sub 5) was synthesized in the range 10-20 GPa readily upon heating at temperature in the range 1500-2500 K. Upon decompression and further heating we observed the decomposition of Fe (sub 4) O (sub 5) at approximately 5 GPa and 1800 K, to wustite and magnetite; whereas cold decompression shows that orthorhombic Fe (sub 4) O (sub 5) is a phase retrievable to ambient conditions. The new Fe-O compound has a broad fundamental and applicative significance, spanning planetary science, physics, chemistry and materials science. Also, the new iron oxide is a plausible phase of deep Earth, considering that it is rather reduced and taking into account the high heterogeneity of the upper mantle. Many peridotite from deep (>200-300 km) subduction zones contain olivine and garnet rich in Fe (sub 3) O (sub 4) lamellae exsolution which attest to the decompression of precursor phases that had formed at profound depths preceding mantle upwelling. Microdiamonds from UHP gneisses also contain abundant Fe (sub x) O (sub y) nanometric inclusions whose structures and stoichiometries are not known yet, though the depth of the host rock subduction is determined as >250 km. These examples and recent findings of iron oxides coexisting with wustite and ferrites as inclusions in superdeep diamonds from Brazil suggest potential areas for searching for natural Fe (sub 4) O (sub 5) within terrestrial rocks. The importance of Fe (sub 4) O (sub 5) would greatly exceed its abundance for the role it might have in redox equilibria that, in turn, affect elements speciation and partitioning.

Reads derived from known microorganisms can easily be identified and analyzed using fast homology search algorithms and a suitable reference database, but the unknown sequences are often ignored in further analyses, biasing conclusions. Nevertheless, it is possible to use more data in a comparative metagenomic analysis by creating a cross-assembly of all reads, i.e. a single assembly of reads from different samples. Comparative metagenomics studies the interrelationships between metagenomes from different samples. Using an assembly algorithm is a fast and intuitive way to link (partially) homologous reads without requiring a database of reference sequences.Results: Here, we introduce crAss, a novel bioinformatic tool that enables fast simple analysis of cross-assembly files, yielding distances between all metagenomic sample pairs and an insightful image displaying the similarities.

This is a time-consuming task that is computationally intensive (though not computationally complex). Here we present a novel approach to annotate metagenomes using unique k-mer oligopeptide sequences from 7 to 12 amino acids long. We demonstrate that k-mer-based annotations are faster and approach the sensitivity and precision of blastx-based annotations without loosing accuracy. A last-common ancestor approach was also developed to describe the members of the community.

We provide new estimates for the energy consumed and greenhouse gases (GHGs) emitted during enzyme and yeast manufacture, including contributions from key ingredients such as starch, glucose, and molasses. We incorporated these data into Argonne National Laboratory's Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation model and observed that enzymes and yeast together contribute 1.4 and 27 % of farm-to-pump GHG emissions for corn and cellulosic ethanol, respectively. Over the course of the entire corn ethanol life cycle, yeast and enzymes contribute a negligible amount of GHG emissions, but increase GHG emissions from the cellulosic ethanol life cycle by 5.6 g CO sub(2)e/MJ.

The structures of single mutants at residue 58 have shown larger deviations in another part of the protein molecule than at the site of the mutation. Closer examination of the crystal packing has revealed the origin of this unexpected structural change. The site of mutation is within Van der Waals distance from another protein molecule related by a crystallographic twofold axis within the crystal. The structural changes occurred at or near the mutation site have led to a slight adjustment of the surface residues in contact. The observed deviations between the native and the mutant molecular structures are derived from the new crystal packing even though the two crystals are essentially isomorphous. Without careful consideration of the crystal lattice a non-expert looking at only the coordinates deposited in the Protein Data Bank could draw erroneous conclusion that mutation in one part of the molecule affected the structure of the protein in a distant part of the molecule.

Using the Eastern Desert (ED) of Egypt (225,000 km (super 2) ) and the Sinai Peninsula (61,000 km (super 2) ) as test sites, we demonstrate practical and cost-effective integrated (geochemistry, geophysics, and modeling) solutions that utilize web-based geographic information system (GIS) (http://www.esrs.wmich.edu/webmap) technologies and take advantage of readily available global remote sensing data sets. Adopted methodologies allowed: (1) development of conceptual models for hydrogeologic settings conducive to groundwater entrapment and augmentation, including groundwater in fractured basement aquifers, groundwater impounded by dike swarms crosscutting alluvial aquifers, and groundwater residing in alluvial aquifers associated with ascending deep-seated fossil waters; (2) selection of criteria to identify and validate the preferred distribution of each of these aquifer types and usage of the selected criteria and observations from the GIS data sets to identify, test, and refine potential well locations; and (3) construction and calibration of hydrologic models to estimate average annual recharge over the major watersheds in the Sinai (463 X 10 (super 6) m (super 3) /yr) and ED (171 X 10 (super 6) m (super 3) /yr) and the average modern contributions to Nubian fossil aquifers (Sinai: 13 X 10 (super 6) m (super 3) /yr), and to model the partitioning of precipitation as a function of precipitation amounts. The successful application of the integrated and cost-effective methodologies developed for the study areas should invite similar applications in arid regions elsewhere.

In situ measurements of the specular reflectivity signal to a vertical structural resolution of 0.45 Aa are used to define the interfacial structure, including vertical displacement patterns of the Ca and CO (sub 3) groups as well as the nature of interfacial water. These new data show two organized interfacial water layers, consistent with previous results, and distortion of the interfacial calcite structure to a depth of four to six unit cells, at least two deeper than previously reported. These results are in reasonable agreement with recent computational studies, at least in terms of the locations of the first and second water layers. The difference between the interfacial structure derived from previous X-ray reflectivity results and that presented here emphasizes the need for high-precision measurements to provide a robust understanding of the interfacial structures of reactive minerals in aqueous environments.

Here, we demonstrate an analysis of pristine and modified CNTs, in dry and wet state using soft X-ray spectromicroscopy with energies around the C 1s K-shell edge (280eV-300eV). Apart from that, suspensions of the CNTs and the colloidal fraction as well as the extracted humic substances of a chernozem soil sample were studied. The effect of the different sample environments on the CNTs were observable both in the microscopic images and the spectral data, e.g., in aqueous environment the CNTs built clusters. Since CNTs are mainly analyzed under sterile laboratory conditions, this study intends to show how to investigate CNTs and their interaction with other substances under ambient conditions. One of the major objectives was, whether differences between CNTs and organic soil particles are distinguishable at all, and subsequently, how to describe the observed interactions.

In light of predicted climate change and a more unified approach to mitigate greenhouse gas emissions, the soil's ability to sequester C, and thus to act as a sink or a source for atmospheric CO (sub 2) has received growing interest. Organomineral assemblages are a unique niche in C cycling, with large capacity for storing anthropogenic C. However, the underlying biogeochemical mechanisms for C sequestration through organomineral associations are not yet well understood. One of the major challenges to study C sequestration in organomineral assemblages is lack of non-invasive analytical tools with a potential to obtain molecular-level information about the interactions between C and mineral components in submicron geochemical environments. In the present study, we have effectively employed synchrotron-based STXM-NEXAFS spectroscopy to access the K- and L-edges of biogeochemically relevant elements (C, N, Ca, Fe, Al, Si) to identify and image micro- and nano-C sequestration environments, and conduct submicron-level investigation of the compositional chemistry and other interactive features of C and minerals present in these hotspots using ultrathin section of intact organomineral assemblage. The C K-edge NEXAFS spectromicroscopy micrographs clearly demonstrated the existence of spatially distinct seemingly terminal micro- and nano-C repository zones, where organic C was sequestered in apparent agglomeration in the investigated organomineral assemblage. These submicron-C repository environments were only a few micrometers apart from each other; yet they were considerably different compositionally from each other. The organic C in the first repository environment was pyrogenic in origin, largely composed of quinone, phenols, ketones and aromatic ring structures. However, the second hotspot was dominated by filament-like structure, with striking similarity to the C 1s NEXAFS spectral signatures of organic C isolated from soil fungal and bacteria, and dominated by resonances from aliphatic-C and C=N bonds of imidazol structures, carboxyl/carbonyl-C, amide- and O-alkyl-C functionalities. The composition of organic C in the organomineral interface around the strand-like structure was highly complex and composed of polysaccharides, amino sugars, amino acids, nucleic acids, and phospholipid fatty acid structures with polar and non-polar termini. The chemistry of mineral matter in the organomineral interface was also equally complex, ranging from Ca, Fe and Al ions, Fe and Al oxides, hydroxides and oxyhydroxides to phyllosilicates, which could provide a variety of polyvalent cations, hydroxyl surface functional groups and edge sites that can attract and bind microbial biomolecules. Based on the enormous complexity of the organic C functionalities and the coexistence of various inorganic components in the organomineral interface, it is possible to suggest that no single binding mechanism could be accountable for the organic C stored in the investigated submicron-C repository environment. Our results seem to suggest that the apparent C sequestration in the micro- and nano-C repository environment appear to be the cumulative result of physical protection and heterogeneous binding mechanisms ranging from ion exchange, hydrogen bonding, and hydrophobic bonding on silicate clay-organic complexes to adsorption on external and internal surfaces of clay minerals.

A key assumption in these studies is that bioenergy crops will be grown in a manner similar to current agricultural crops such as corn and hence would affect the environment similarly. In this study, we investigate an alternative cropping system where bioenergy crops are grown in buffer strips adjacent to current agricultural crops such that nutrients present in runoff and leachate from the traditional row-crops are reused by the bioenergy crops (switchgrass, miscanthus and native prairie grasses) in the buffer strips, thus providing environmental services and meeting economic needs of farmers. The process-based biogeochemical model Denitrification-Decomposition (DNDC) was used to simulate crop yield, nitrous oxide production and nitrate concentrations in leachate for a typical agricultural field in Illinois. Model parameters have been developed for the first time for miscanthus and switchgrass in DNDC. Results from model simulations indicated that growing bioenergy crops in buffer strips mitigated nutrient runoff, reduced nitrate concentrations in leachate by 60-70% and resulted in a reduction of 50-90% in nitrous oxide emissions compared with traditional cropping systems. While all the bioenergy crop buffers had significant positive environmental benefits, switchgrass performed the best with respect to minimizing nutrient runoff and nitrous oxide emissions, while miscanthus had the highest yield. Overall, our model results indicated that the bioenergy crops grown in these buffer strips achieved yields that are comparable to those obtained for traditional agricultural systems while simultaneously providing environmental services and could be used to design sustainable agricultural landscapes.

We find a steep 1990-2009 decline of -0.046+ or -0.010 ng m (super -3) a (super -1) (-2.5% a (super -1) ) over the NA (steeper than at Northern Hemispheric land sites) but no significant decline over the SA. Surface water Hg (super 0) measurements in the NA show a decline of -5.7% a (super -1) since 1999, and limited subsurface ocean data show an approximately 80% decline from 1980 to present. We use a coupled global atmosphere-ocean model to show that the decline in NA atmospheric concentrations can be explained by decreasing oceanic evasion from the NA driven by declining subsurface water Hg concentrations. We speculate that this large historical decline of Hg in the NA Ocean could have been caused by decreasing Hg inputs from rivers and wastewater and by changes in the oxidant chemistry of the atmospheric marine boundary layer.

While investigating the stability and decomposition products of siderite (FeCO (sub 3) ) at conditions of the Earth's mantle we obtained, at 10 GPa and about 1800 K, a single crystal of unknown phase. Diffraction data were obtained using highly focused synchrotron x-rays. Structural solution and refinement of the single crystal diffraction pattern indicate that the phase is a new compound with formula Fe (sub 4) O (sub 5) [1]. The phase has orthorhombic symmetry where iron is 6-coordinated in layers of trigonal prisms and edge-sharing octahedra. First-principle calculations show that Fe (sub 4) O (sub 5) is stable at high pressure with respect to its possible breakdown products. We performed several HP-HT syntheses starting from mixtures of pure Fe+Fe (sub 3) O (sub 4) and Fe+Fe (sub 2) O (sub 3) . Fe (sub 4) O (sub 5) was synthesized in the range 10-20 GPa readily upon heating at temperature in the range 1500-2500 K. Upon decompression and further heating we observed the decomposition of Fe (sub 4) O (sub 5) at approximately 5GPa and 1800K, to wuestite and magnetite; whereas cold decompression shows that orthorhombic Fe (sub 4) O (sub 5) is a phase retrievable to ambient conditions. The new Fe-O compound has a broad fundamental and applicative significance, spanning planetary science, physics, chemistry and materials science. Also, the new iron oxide is a plausible phase of deep Earth, considering that it is rather reduced and taking into account the high heterogeneity of the upper mantle. Many peridotite from deep (>200-300km) subduction zones contain olivine and garnet rich in Fe (sub 3) O (sub 4) lamellae exsolution which attest to the decompression of precursor phases that had formed at profound depths preceding mantle upwelling [2]. Microdiamonds from UHP gneisses also contain abundant Fe (sub x) O (sub y) nanometric inclusions whose structures and stoichiometries are not known yet, though the depth of the host rock subduction is determined as >250 km [3]. These examples and recent findings of iron oxides coexisting with wuestite and ferrites as inclusions in superdeep diamonds from Brazil [4] suggest potential areas for searching for natural Fe (sub 4) O (sub 5) within terrestrial rocks.

AN - 1237084023; 22831969 AB - Mean blood cadmium (B-Cd) concentrations are two- to threefold higher in smokers than in nonsmokers. The basis for this phenomenon is not well understood. We conducted a detailed, multifaceted study of cadmium exposure in smokers. Groups were older smokers (62±4 years, n = 25, 20% male) and nonsmokers (62±3 years, n = 16, 31% male). Each subject's cigarettes were machine smoked, generating individually paired measures of inhaled cadmium (I-Cd) versus B-Cd; I-Cd and B-Cd were each evaluated three times, at monthly intervals. Urine cadmium (U-Cd) was analyzed for comparison. In four smokers, a duplicate-diet study was conducted, along with a kinetic study of plasma cadmium versus B-Cd. Female smokers had a mean B-Cd of 1.21ng Cd/ml, with a nearly 10-fold range (0.29-2.74ng Cd/ml); nonsmokers had a lower mean B-Cd, 0.35ng Cd/ml (p < 0.05), and narrower range (0.20-0.61ng Cd/ml). Means and ranges for males were similar. Estimates of cadmium amounts inhaled daily for our subjects smoking ≥ 20 cigarettes/day were far less than the 15 µg Cd reported to be ingested daily via diet. This I-Cd amount was too low to alone explain the 3.5-fold elevation of B-Cd in our smokers, even assuming greater cadmium absorption via lungs than gastrointestinal tract; cadmium accumulated in smokers' lungs may provide the added cadmium. Finally, B-Cd appeared to be linearly related to I-Cd values in 75% of smokers, whereas 25% had far higher B-Cd, implying a possible heterogeneity among smokers regarding circulating cadmium concentrations and potentially cadmium toxicity.

17317909 AB - The sodium battery has the potential to be the next generation rechargeable system which utilizes cheaper and more abundant sodium material but affords nearly the same power as lithium batteries. One of the key barriers for the sodium battery is the lack of stable anode materials which can insert sodium ions reversibly at relatively low potential. This contribution reports the sodium insertion in a series of organic carboxylate based materials: (C sub(8)H sub(4)Na sub(2)O sub(4)), (C sub(8)H sub(6)O sub(4)), (C sub(8)H sub(5)NaO sub(4)), (C sub(8)Na sub(2)F sub(4)O sub(4)), (C sub(10)H sub(2)Na sub(4)O sub(8)), (C sub(14)H sub(4)O sub(6)) and (C sub(14)H sub(4)Na sub(4)O sub(8)) at low voltage (below 0.6 V vs.Na/Na super(+)). These organic anode materials can insert reversibly up to 2 Na per molecule with good cycleability.

Physical methods allow the fabrication of a variety of magnetic structures with tightly controlled magnetic properties and geometry, which makes them very attractive for a cost-efficient mass-production in the fast growing field of nanomedicine. Stand-alone fabricated particles along with integrated devices combining lithographically defined magnetic structures and synthesized magnetic tags will be considered. Applications of microfabricated multifunctional magnetic structures for future medicinal purposes range from ultrasensitive in vitro diagnostic bioassays, DNA sequencing and microfluidic cell sorting to magnetomechanical actuation, cargo delivery, contrast enhancement and heating therapy.

The expression of Mmr is controlled by the TetR-like transcriptional regulator Rv3066, whose open reading frame is located downstream of the mmr operon. To understand the structural basis of Rv3066 regulation, we have determined the crystal structures of Rv3066, both in the absence and presence of bound ethidium, revealing an asymmetric homodimeric two-domain molecule with an entirely helical architecture. The structures underscore the flexibility and plasticity of the regulator essential for multidrug recognition. Comparison of the apo-Rv3066 and Rv3066-ethidium crystal structures suggests that the conformational changes leading to drug-mediated derepression is primarily due to a rigid body rotational motion within the dimer interface of the regulator. The Rv3066 regulator creates a multidrug-binding pocket, which contains five aromatic residues. The bound ethidium is found buried within the multidrug-binding site, where extensive aromatic stacking interactions seemingly govern the binding. In vitro studies reveal that the dimeric Rv3066 regulator binds to a 14-bp palindromic inverted repeat sequence in the nanomolar range. These findings provide new insight into the mechanisms of ligand binding and Rv3066 regulation.

We measured the beta -factors of goethite FeO(OH), potassium-jarosite KFe (sub 3) (SO (sub 4) ) (sub 2) (OH) (sub 6) , and hydronium-jarosite (H (sub 3) O)Fe (sub 3) (SO (sub 4) ) (sub 2) (OH) (sub 6) , by Nuclear Resonant Inelastic X-ray Scattering (NRIXS, also known as Nuclear Resonance Vibrational Spectroscopy - NRVS or Nuclear Inelastic Scattering - NIS) at the Advanced Photon Source. These measurements were made on synthetic minerals enriched in (super 57) Fe. A new method (i.e., the general moment approach) is presented to calculate beta -factors from the moments of the NRIXS spectrum S(E). The first term in the moment expansion controls iron isotopic fractionation at high temperature and corresponds to the mean force constant of the iron bonds, a quantity that is readily measured and often reported in NRIXS studies. The mean force constants of goethite, potassium-jarosite, and hydronium-jarosite are 314+ or -14, 264+ or -12, and 310+ or -14 N/m, respectively (uncertainties include statistical and systematic errors). The general moment approach gives (super 56) Fe/ (super 54) Fe beta -factors of 9.7, 8.3, and 9.5 ppm at 22 degrees C for these minerals. The beta -factor of goethite measured by NRIXS is larger than that estimated by combining results from laboratory exchange experiments and calculations based on electronic structure theory. Similar issues have been identified previously for other pairs of mineral-aqueous species, which could reflect inadequacies of approaches based on electronic structure theory to calculate absolute beta -factors (differences in beta -factors between aqueous species may be more accurate) or failure of laboratory experiments to measure mineral-fluid equilibrium isotopic fractionation at low temperature. We apply the force constant approach to published NRIXS data and report 1000Xlnbeta for important Fe-bearing phases of geological and biochemical relevance such as myoglobin, cytochrome f, pyroxene, metal, troilite, chalcopyrite, hematite, and magnetite.

The growth mechanism including the morphological and crystalline evolution has been carefully studied with time-dependent X-ray diffraction, electron microscopy, and controlled synthesis. The as-synthesized MnO(2) nanostructures are incorporated in air cathodes of lithium--air batteries as electrocatalysts for the oxygen reduction and evolution reactions. The characterization reveals that the electrodes made of single-crystalline α-MnO(2) nanotubes exhibit much better stability than those made of α-MnO(2) nanowires and δ-MnO(2) nanosheet-based microflowers in both charge and discharge processes.

AN - 1038229116; 22817384 AB - Silicon is of significant interest as a next-generation anode material for lithium-ion batteries due to its extremely high capacity. The reaction of lithium with crystalline silicon is known to present a rich range of phenomena, including electrochemical solid state amorphization, crystallization at full lithiation of a Li(15)Si(4) phase, hysteresis in the first lithiation-delithiation cycle, and highly anisotropic lithiation in crystalline samples. Very little is known about these processes at an atomistic level, however. To provide fundamental insights into these issues, we develop and apply a first principles, history-dependent, lithium insertion and removal algorithm to model the process of lithiation and subsequent delithiation of crystalline Si. The simulations give a realistic atomistic picture of lithiation demonstrating, for the first time, the amorphization process and hinting at the formation of the Li(15)Si(4) phase. Voltages obtained from the simulations show that lithiation of the (110) surface is thermodynamically more favorable than lithiation of the (100) or (111) surfaces, providing an explanation for the drastic lithiation anisotropy seen in experiments on Si micro- and nanostructures. Analysis of the delithiation and relithiation processes also provides insights into the underlying physics of the lithiation-delithiation hysteresis, thus providing firm conceptual foundations for future design of improved Si-based anodes for Li ion battery applications.

Since a significant amount of scCO sub(2) is sequestered below ground in the process, a constant supply is required. We therefore combined the scCO sub(2) geothermal power plant with an upstream coal power plant that captured a portion of its CO sub(2) emissions, compressed it to scCO sub(2), and transported the scCO sub(2) by pipeline to the geothermal power plant. Emissions and energy consumption from all operations spanning coal mining and plant construction through power production were considered, including increases in coal use to meet steam demand for the carbon capture. The results indicated that the electricity produced by the geothermal plant more than balanced the increase in energy use resulting from carbon capture at the coal power plant. The effective heat rate (BTU coal per total kW?h of electricity generated, coal plus geothermal) was comparable to that of traditional coal, but the ratio of life cycle emissions from the combined system to that of traditional coal was 15% when 90% carbon capture efficiency was assumed and when leakage from the surface was neglected. Contributions from surface leakage were estimated with a simple model for several hypothetical surface leakage rates.

At 18 wells, we trapped the microbes that attached to aquifer sediment and used molecular techniques to examine the bacterial populations. We used multivariate statistics to compare the composition of bacterial communities among the wells with respect to the chemistry of the groundwater. We found groundwater at each well was considerably richer in ferrous iron than sulfide, indicating iron-reducing bacteria should, by established criteria, dominate the sulfate reducers. Our results show, however, that areas where groundwater contains more than a negligible amount of sulfate (>0.03 mM), populations related to sulfate reducers of the generaDesulfobacter and Desulfobulbus were of nearly equal abundance with putative iron reducers related to Geobacter, Geothrix, and Desulfuromonas. Whereas sulfate is a key discriminant of bacterial community structure, we observed no statistical relationship between the distribution of bacterial populations in this aquifer and the concentration of either ferrous iron or dissolved sulfide. These results call into question the validity of using the relative concentration of these two ions to predict the nature of bacterial activity in an aquifer. Sulfate reducers and iron reducers do not appear to be segregated into discrete zones in the aquifer, as would be predicted by the theory of competitive exclusion. Instead, we find the two groups coexist in the subsurface in what we suggest is a mutualistic relationship. Key Points * The amount of sulfate in groundwater controls bacterial community structure * Iron reducers and sulfate reducers co-exist in this aquifer * Ferrous iron and sulfide do not correspond to bacterial community structure JF - Water Resources Research AU - Flynn, Theodore M AU - Sanford, Robert A AU - Santo Domingo, Jorge W AU - Ashbolt, Nicholas J AU - Levine, Audrey D AU - Bethke, Craig M AD - Department of Geology, University of Illinois at Urbana-Champaign, Urbana, Illinois, USA., tflynn@anl.gov Y1 - 2012/09// PY - 2012 DA - Sep 2012 SP - [np] PB - American Geophysical Union, 2000 Florida Ave., N.W.

Many aspects of this complexity, from the number of species to the total number of interactions, are currently very difficult to examine directly. However, extraordinary efforts are being made to make these systems accessible to scientific investigation. While recent advances in high-throughput sequencing technologies have improved accessibility to the taxonomic and functional diversity of complex communities, monitoring the dynamics of these systems over time and space - using appropriate experimental design - is still expensive. Fortunately, modeling can be used as a lens to focus low-resolution observations of community dynamics to enable mathematical abstractions of functional and taxonomic dynamics across space and time. Here, we review the approaches for modeling bacterial diversity at both the very large and the very small scales at which microbial systems interact with their environments. We show that modeling can help to connect biogeochemical processes to specific microbial metabolic pathways.

Specifically, comparison between seismic V (sub P) - rho profiles of the core and candidate Fe alloys provides first-order information on the amount and type of potential light elements-including H, C, O, Si, and/or S-needed to compensate the density deficit of the core. To address this issue, here we have surveyed and analyzed the literature results in conjunction with newly measured V (sub P) - rho results of hexagonal closest-packed (hcp) Fe and hcp-Fe (sub 0.85) Si (sub 0.15) alloy using in situ high-energy resolution inelastic X-ray scattering and X-ray diffraction. The nature of the Fe-Si alloy where Si is readily soluble in Fe represents an ideal solid-solution case to better understand the light-element alloying effects. Our results show that high temperature significantly decreases the V (sub P) of hcp-Fe at high pressures, and the Fe-Si alloy exhibits similar high-pressure V (sub P) - rho behavior to hcp-Fe via a constant density offset. These V (sub P) - rho data at a given temperature can be better described by an empirical power-law function with a concave behavior at higher densities than with a linear approximation. Our new datasets, together with literature results, allow us to build new V (sub P) - rho models of Fe alloys in order to determine the chemical composition of the core. Our models show that the V (sub P) - rho profile of Fe with 8 wt% Si at 6,000 K matches well with the Preliminary Reference Earth Model of the inner core.

BEAMS is a Bayesian framework for using data from multiple species in statistical inference when one has the probability that each data point belongs to a given species, corresponding in this context to different types of SNe with their probabilities derived from their multi-band light curves. We run the BEAMS algorithm on both Gaussian and more realistic SNANA simulations with of order 10 (super 4) SNe, testing the algorithm against various pitfalls one might expect in the new and somewhat uncharted territory of photometric SN cosmology. We compare the performance of BEAMS to that of both mock spectroscopic surveys and photometric samples that have been cut using typical selection criteria. The latter typically either are biased due to contamination or have significantly larger contours in the cosmological parameters due to small data sets. We then apply BEAMS to the 792 SDSS-II photometric SNe with host spectroscopic redshifts. In this case, BEAMS reduces the area of the Omega (sub m ) , Omega (sub Lambda ) contours by a factor of three relative to the case where only spectroscopically confirmed data are used (297 SNe). In the case of flatness, the constraints obtained on the matter density applying BEAMS to the photometric SDSS-II data are Omega (super BEAMS) (sub m ) = 0.194 + or - 0.07. This illustrates the potential power of BEAMS for future large photometric SN surveys such as Large Synoptic Survey Telescope. Copyright (Copyright) 2012. The American Astronomical Society.

Inaccurate and inconsistent annotations exist as a result of errors generated from mass automated annotation, and currently act as a barrier to the application of bioinformatics. The purpose of this effort was to improve the SEED by improving the connection of functional roles to literature references. Direct literature references (DLits), found through searches of PubMed and other online databases such as SwissProt, were attached to protein sequences within the PubSEED to provide literature support for the roughly 2,500 distinct functional roles used to construct metabolic models within the Model SEED. Only DLits in which a researcher asserted the function of a protein were attached to sequences. Starting from a list of 1,072 functional roles that did not previously have DLit support, we were able to connect sequences to literature for 655 functional roles, at least 484 of which were in the original list of unsupported roles. When added to the existing set of sequences having DLits, the resulting set of DLit-sequence pairs (the foundation set) now connects approximately 4,300 DLits to approximately 5,600 distinct protein sequences obtained from approximately 16,000 genes (some of these genes have identical protein sequences). From the foundation set, we construct projection sets such that each set contains one member of the foundation set and projections of its functional role onto similar genes. The projection sets revealed 120 inconsistent annotations within the SEED. Two types of inconsistencies were corrected through manual annotation in the PubSEED: instances in which two identical protein sequences had been annotated with different functions, and instances when projected functions contradicted previous annotations. 26,785 changes to gene function assignment, 219 of which were to previously uncharacterized proteins, resulted in a more consistent and accurate set of input data from which to construct revised metabolic models within the Model SEED.

We describe a bioclimatic modeling approach that leverages artificial neural networks to predict microbial community structure as a function of environmental parameters and microbial interactions. This method was better at predicting observed community structure than were any of several single-species models that do not incorporate biotic interactions. The model was used to interpolate and extrapolate community structure over time with an average Bray-Curtis similarity of 89.7. Additionally, community structure was extrapolated geographically to create the first microbial map derived from single-point observations. This method can be generalized to the many microbial ecosystems for which detailed taxonomic data are currently being generated, providing an observation-based modeling technique for predicting microbial taxonomic structure in ecological studies.

Another objective is to assess the feasibility of using the fuel discharged at the minimum required BU for fabricating the starter of an additional B&B core without separation of actinides and most of the solid fission products. A melt-refining process is used to remove gaseous and volatile fission products and to replace the cladding when it reaches its 200 displacements per atom radiation damage limit. Additional objectives are to assess the validity of a simplified zero-dimensional (0-D) neutron balance analysis for determination of the minimum BU required and the maximum BU attainable in a B&B mode of operation and to apply this 0-D methodology to assess the feasibility of establishing a B&B mode of operation in fast reactor cores made of different combinations of fuels, coolants, and structural materials. It is found that the minimum BU required to sustain the B&B mode in the referenced depleted uranium-fueled B&B reactor is 19.4% FIMA. The number of excess neutrons that can be generated by the fuel discharged at 19.4% FIMA is found sufficient to establish the B&B mode in another B&B core. The net doubling time for starting new B&B reactors with fuel discharged from operating B&B reactors is 12.3 yr. The minimum BU required to sustain the B&B mode of operation in alternative core designs was found to be 29% FIMA when using Pb-Bi coolant with metallic uranium fuel and 40% FIMA when using nitride fuel with sodium coolant. The B&B mode of operation cannot be established using thorium fuel and liquid-metal coolant. The results derived from the neutron balance analysis strongly depend on the value of the estimated neutron leakage probability and the fraction of neutrons lost in the reactivity control systems. A neutron balance performed using a simplified 0-D core model, although not accurate due to, primarily, inaccurate spectra predictions, provides reasonable estimates of the minimum required and the maximum attainable BUs despite the fact that its k(x) evolution prediction is inaccurate. The 0-D approach can save much computational effort and time and is found to be useful for scoping analysis.

This study investigates the location and occurrence of this inorganic material to the angstrom level using non-invasive small angle scattering techniques. Microstructural analysis conducted on matrix and vitrain samples, collected from the subbituminous coals of the Huntly coalfield, found that the inorganic material is located in the 12.5Aa65% of the variance in community diversity. The results suggested that seasonal changes in environmental variables are more important than trophic interactions. Interestingly, microbial association network analysis showed that correlations in abundance were stronger within bacterial taxa rather than between bacteria and eukaryotes, or between bacteria and environmental variables.

AN - 917854793; 22148185 AB - Tailoring nanoarchitecture of materials offers unprecedented opportunities in utilization of their functional properties. Nanostructures of vanadium oxide, synthesized by electrochemical deposition, are studied as a cathode material for rechargeable Na-ion batteries. Ex situ and in situ synchrotron characterizations revealed the presence of an electrochemically responsive bilayered structure with adjustable intralayer spacing that accommodates intercalation of Na(+) ions. Sodium intake induces organization of overall structure with appearance of both long- and short-range order, while deintercalation is accompanied with the loss of long-range order, whereas short-range order is preserved. Nanostructured electrodes achieve theoretical reversible capacity for Na(2)V(2)O(5) stochiometry of 250 mAh/g. The stability evaluation during charge-discharge cycles at room temperature revealed an efficient 3 V cathode material with superb performance: energy density of ~760 Wh/kg and power density of 1200 W/kg. These results demonstrate feasibility of development of the ambient temperature Na-ion rechargeable batteries by employment of electrodes with tailored nanoarchitectures.

Losses of up to a third of particulate organic carbon occurred after continuous exposure to full-strength sunlight for dozens of hours, with similar amounts appearing as photodissolved organic carbon. Nitrogen dissolved similarly, appearing partly as ammonium. Modified experiments with interruption of irradiation to include extended dark incubation periods increased loss of total organic carbon, implying remineralization by some combination of light and microbes. These photodissolution reactions respond strongly to water content, with reaction extent under air-dry to fully wet conditions increasing by a factor of 3-4 fold. Light limitation was explored using lamp intensity and soil depth experiments. Reaction extent varied linearly with lamp intensity. Depth experiments indicate that attenuation of reaction occurs within the top tens to hundreds of micrometers of soil depth. Our data allow only order-of-magnitude extrapolations to field conditions, but suggest that this type of reaction could induce loss of 10-20% of soil organic carbon in the top 10cm horizon over a century. It may therefore have contributed to historical losses of soil carbon via agriculture, and should be considered in soil management on similar time scales.

We considered approximately 400 emission control measures to reduce these pollutants by using current technology and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming approximately 0.5 degree C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deaths from outdoor air pollution and increases annual crop yields by 30 to 135 million metric tons due to ozone reductions in 2030 and beyond. Benefits of methane emissions reductions are valued at $700 to $5000 per metric ton, which is well above typical marginal abatement costs (less than $250). The selected controls target different sources and influence climate on shorter time scales than those of carbon dioxide-reduction measures. Implementing both substantially reduces the risks of crossing the 2 degree C threshold.

N1 - Last updated - 2017-01-24 ER - TY - JOUR T1 - Pore formation during dehydration of a polycrystalline gypsum sample observed and quantified in a time-series synchrotron X-ray micro-tomography experiment AN - 1777466787; 2016-026478 AB - We conducted an in-situ X-ray micro-computed tomography heating experiment at the Advanced Photon Source (USA) to dehydrate an unconfined 2.3 mm diameter cylinder of Volterra Gypsum. We used a purpose-built X-ray transparent furnace to heat the sample to 388 K for a total of 310 min to acquire a three-dimensional time-series tomography dataset comprising nine time steps. The voxel size of 2.2 mu m (super 3) proved sufficient to pinpoint reaction initiation and the organization of drainage architecture in space and time. We observed that dehydration commences across a narrow front, which propagates from the margins to the centre of the sample in more than four hours. The advance of this front can be fitted with a square-root function, implying that the initiation of the reaction in the sample can be described as a diffusion process. Novel parallelized computer codes allow quantifying the geometry of the porosity and the drainage architecture from the very large tomographic datasets (2048 (super 3) voxels) in unprecedented detail. We determined position, volume, shape and orientation of each resolvable pore and tracked these properties over the duration of the experiment. We found that the pore-size distribution follows a power law. Pores tend to be anisotropic but rarely crack-shaped and have a preferred orientation, likely controlled by a pre-existing fabric in the sample. With on-going dehydration, pores coalesce into a single interconnected pore cluster that is connected to the surface of the sample cylinder and provides an effective drainage pathway. Our observations can be summarized in a model in which gypsum is stabilized by thermal expansion stresses and locally increased pore fluid pressures until the dehydration front approaches to within about 100 mu m. Then, the internal stresses are released and dehydration happens efficiently, resulting in new pore space. Pressure release, the production of pores and the advance of the front are coupled in a feedback loop.

These solutions, referred to as acid mine drainage (AMD), adversely affect environmental quality. When AMD mixes with neutral water bodies, such as in rivers or during wetland treatment, interacts with rock surfaces, or reacts with lime during remediation, neutralization occurs. As a result, ferric iron (Fe (super 3+) ) hydrolyzes and precipitates as Fe oxyhydroxide nanoparticles, such as ferrihydrite and schwertmannite. However, the formation pathways of these nanoparticles are relatively unknown largely due to their rapid formation rates and low abundances of initially-formed species. In this study, we used in situ time-resolved synchrotron radiation X-ray diffraction (XRD), quick-scanning extended X-ray absorption fine structure (QEXAFs) and UV-Vis spectroscopic techniques to study the products formed initially (2 < t < 60 minutes) when ferric iron sulfate solutions ([Fe (super 3+) ] = 0.2 M) are partially neutralized ([HCO (sub 3) (super -) ]/[Fe (super 3+) ] < 3) by addition of NaHCO (sub 3) . When [HCO (sub 3) (super -) ]/[Fe (super 3+) ] = 0.6 (initial pH approximately 2.2), the only particles formed were ferrihydrite-like clusters that were stable throughout the duration of the experiment. When [HCO (sub 3) (super -) ]/[Fe (super 3+) ] = 1 (initial pH approximately 2.5), the ferrihydrite-like molecular clusters formed initially but mostly disappeared and were replaced by schwertmannite. Schwertmannite and larger ferrihydrite particles formed immediately when [HCO (sub 3) (super -) ]/[Fe (super 3+) ] = 2 (initial pH approximately 2.7), but the ferrihydrite particles completely disappeared and were replaced by schwertmannite. The schwertmannite particle size increased with reaction time, and extensive particle aggregation occurred. The ferrihydrite-like cluster is very intriguing and its structure deserves further characterization. The data are consistent with Fe (sub 13) having Baker-Figgis delta -keggin structure, i.e., the motif in the ferrihydrite structure proposed by Michel et al.. The existence of the cluster may result from sulfate binding on its surface, preventing the cluster from growing into larger ferrihydrite particles. In conclusion, the results suggest that particular molecular clusters and small nanoparticles may be important, early-formed components of natural acidic solutions.

The mineralogy and oxidation state (speciation) of iron have been shown to influence fractional iron solubility (soluble iron/total iron). In this study, iron speciation was determined in single particles at urban and rural sites in Georgia USA using synchrotron-based techniques, such as X-ray Absorption Near-Edge Structure (XANES) spectroscopy and microscopic X-ray fluorescence measurements. Soluble and total iron content (soluble + insoluble iron) of these samples was measured using spectrophotometry and synchrotron-based techniques, respectively. These bulk measurements were combined with synchrotron-based measurements to investigate the relationship between iron speciation and fractional iron solubility in ambient aerosols. XANES measurements indicate that iron in the single particles was present as a mixture of Fe(II) and Fe(III), with Fe(II) content generally between 5 and 35% (mean: approximately 25%). XANES and elemental analyses (e.g. elemental molar ratios of single particles based on microscopic X-ray fluorescence measurements) indicate that a majority (74%) of iron-containing particles are best characterized as Al-substituted Fe-oxides, with a Fe/Al molar ratio of 4.9. The next most abundant group of particles (12%) was Fe-aluminosilicates, with Si/Al molar ratio of 1.4. No correlation was found between fractional iron solubility (soluble iron/total iron) and the abundance of Al-substituted Fe-oxides and Fe-aluminosilicates present in single particles at any of the sites during different seasons, suggesting solubility largely depended on factors other than differences in major iron phases.

In the present study, we collected Trichodesmium colonies from the Sargasso Sea and investigated their elemental signature. Element concentrations and spatial distributions in colonies were compared using inductively coupled plasma mass spectrometry (ICPMS), CHN analysis, and synchrotron x-ray fluorescence (SXRF) mapping. Trichodesmium's cellular stoichiometry of 647C:111N:1P deviated significantly from the canonical Redfield ratio and illustrates the P-limiting condition at the time of sampling. Additionally, ICPMS and SXRF analysis confirmed that the metallome of Trichodesmium is enriched in V, Fe and Ni in comparison to other phytoplankton. Surprisingly, V was the most abundant metal in Trichodesmium, and the V quota was up to 4-fold higher than the corresponding Fe quota. Furthermore, SXRF mapping revealed the presence of V and Fe hotspots. These hotspots typically spanned over several contiguous cells. The spatial distribution of Ni differed from V and Fe and was enriched in transverse walls between attached cells. As hotspots of V, Fe, or Ni were spatially decoupled from each other, we conclude that external adsorption of aerosol particles on Trichodesmium trichomes did not contribute to the elevated element quotas. Fe hotspots were found in only ca. 10% of analysed trichome sections, and Fe enrichment in contiguous cells may be linked to diazocytes as zones of nitrogen fixation in Trichodesmium. In contrast, genomic analyses indicated that V is not directly associated with nitrogenase in Trichodesmium. V maybe used in V-dependent haloperoxidases to protect the oxygen susceptible nitrogen fixing enzyme nitrogenase from reactive oxygen species (ROS) such as hydrogen peroxide, but genomic evidence for such an enzymatic role of V is also currently lacking. The presence of Ni in transverse walls is in agreement with genomic evidence for the presence of Ni-superoxide dismutase and/or NiFe hydrogenase. Both Ni-containing enzymes are beneficial for nitrogen fixation by either inactivation of the ROS species superoxide or the catalyzation of hydrogen, respectively. We conclude that the enrichment of these metals is directly or indirectly linked to nitrogen fixation in Trichodesmium.

The goal of the study was twofold: to examine the impact of scenarios for market penetration and charging of PHEVs on the electric utilities and transmission grid and to estimate the potential reductions in petroleum use and greenhouse gas (GHG) emissions attributable to PHEV miles traveled on primarily grid electricity. Three charging scenarios for PHEVS were examined: (a) begin recharging upon arrival at home at the end of the last daily trip, (b) complete recharging of batteries just before the start of the first daily trip, and (c) any additional charging opportunity during the daytime. The three charging scenarios produced distinct hourly electric load profiles, with the opportunity-charging scenario resulting in a significant increase in load during the daytime. However, when the utility dispatch simulations were run for these charging scenarios in the WECC area, they all exhibited similar marginal-generation mixes (dominated by the natural gas combined-cycle technology) to satisfy the PHEV load, and GHG emissions were within 2 % of each other. A well-to-wheel analysis revealed that the marginal-generation mixes produced 40% to 45% lower GHG emissions by PHEVs than did conventional gasoline internal combustion engine vehicles.

A standard Kirkpatrick-Baez (KB) mirror system uses two separated elliptical mirrors at glancing angles to the X-ray beam and sequentially arranged at 90 degree to each other to focus X-rays successively in the vertical and horizontal directions. A nested KB mirror system has the two mirrors positioned perpendicular and side-by-side to each other. Compared to a standard KB mirror system, Montel optics can focus a larger divergence and the mirrors can have a shorter focal length. As a result, nested mirrors can be fabricated with improved demagnification factor and ultimately smaller focal spot, than with a standard KB arrangement. The nested system is also more compact with an increased working distance, and is more stable, with reduced complexity of mirror stages. However, although Montel optics is commercially available for laboratory X-ray sources, due to technical difficulties they have not been used to microfocus synchrotron radiation X-rays, where ultra-precise mirror surfaces are essential. The main challenge in adapting nested optics for synchrotron microfocusing is to fabricate mirrors with a precise elliptical surface profile at the very edge where the two mirrors meet and where X-rays scatter. For example, in our application to achieve a sub-micron focus with high efficiency, a surface figure root-mean-square (rms) error on the order of 1nm is required in the useable area along the X-ray footprint with a a arrow right 40.1mm-diameter cross section. In this paper we describe promising ways to fabricate precise nested KB mirrors using our profile coating technique and inexpensive flat Si substrates.

Many of these environments are characterized by periodic or seasonal cycling of redox conditions (e.g., redoximorphic soils in areas with seasonal flooding) that create the opportunity for cycling of Fe between oxidized and reduced forms. In recent years evidence has been building that suggests that the green rust mineral fougerite plays a central role in Fe redox cycling in these environments. Carbonate green rust was produced in anoxic defined mineral medium containing 75 mM formate and 80 mM Fe (super III) , in the form of phosphate doped (0.7 mass % P) lepidocrocite, inoculated with Shewanella putrefaciens CN32. The green rust was then oxidized by introducing sterile air into the headspace. After 24 h the suspensions were sparged with sterile Ar and re-inoculated with S. putrefaciens CN32. Samples were collected for measurement of Fe (super II) and characterization of the secondary mineralization products by powder X-ray diffraction, scanning electron microscopy, and (super 57) Fe Mossbauer spectroscopy. Results of the analysis of the product of green rust oxidation were consistent with ferric green rust. In our experiment, the oxidation of green rust by O (sub 2) to ferric green rust occurred over a period of 24 h without the formation of other Fe (super III) oxide phases. However, the initial green rust was formed in the presence of phosphate and sorption of phosphate or silicate by green rust has been shown to promote oxidation of green rust to ferric green rust by suppressing the dissolution of green rust, a prerequisite for the formation of other ferric phases such as lepidocrocite or goethite. After re-inoculation, total Fe (super II) concentrations rebounded to pre-oxidation concentrations and green rust was observed as the dominant secondary mineralization product. Since phosphate and silicate are typically available in soils and sediments, similar conditions may be encountered in-situ. Thus, our results indicate the potential for cycling of green rust between reduced and oxidized forms under redox dynamics similar to those encountered in environments that alternate between iron-reducing and oxic conditions and are consistent with the identification of green rust in soils/sediments with seasonal redox cycling.

It is known that such reactions can be controlled by the presence of solid surfaces. Previous work showed that crystalline Al-hydroxide phases formed on the surface of muscovite mica with an apparent epitaxial relationship to the underlying surface, but the molecular-scale interfacial processes that initiate the reactions are not well understood. We investigated the formation of an Al-hydroxide phase on the basal surface of single crystal muscovite by monitoring changes in muscovite-solution interfacial structure using in-situ high resolution x-ray reflectivity. Experimental solutions were prepared with a fixed total Al content (1 mM) as a function of pH. At pH 4, we observed sorbed Al (super 3+) species formed an approximately 2A thick film. The thickness and the vertical structure of the film matches those of a single Al dioctahedral sheet, i.e., gibbsite, Al(OH) (sub 3) , phase. The films formed at lower pH (2 and 3) are structurally more disordered and are less dense (i.e., covered a smaller fraction of the surface) than that formed at pH 4. These observations can be attributed to decrease in the concentration of hydrolyzed Al species with decreasing pH, both in the solution and at the surface. No film formation was observed at alkaline conditions (pH 9-12) where Al (super 3+) occurs primarily as an anionic species, Al(OH) (sub 4) (super -) . The difference implies that the formation of the film is initiated by adsorption of positively-charged Al species at the negatively charged surface. The results demonstrate that the growth of secondary minerals and the structural control of underlying substrates can be investigated in situ, in real time, and with a molecular-scale resolution. The results also suggest a new capability to characterize the reactivity of nanomineral films with a high resolution.

(super 81) Kr-dating, a concept pursued over the past four decades by numerous laboratories employing a variety of techniques, is now available for the first time to the earth science community at large. This is made possible by the development of ATTA-3, an efficient and selective atom counter based on the Atom Trap Trace Analysis method and capable of measuring both (super 81) Kr/Kr and (super 85) Kr/Kr ratios of environmental samples in the range of 10 (super -14) -10 (super -10) . The instrument was calibrated with 12 samples whose (super 85) Kr/Kr ratios were independently measured using Low Level Decay Counting, including six samples that were measured in a blind arrangement. Compared to the previously reported ATTA-2 instrument, the counting rates of ATTA-3 are higher by two orders of magnitude and the required sample size lower by one order of magnitude. For (super 81) Kr-dating in the age range of 200 - 1,500 kyr, the required sample size is 5 - 10 micro-L STP of krypton gas, which can be extracted from approximately 100 - 200 kg of water or 40 - 80 kg of ice. Moreover, a laser-induced quenching scheme was developed to enable measurements of both the rare (super 81,85) Kr and the abundant (super 83) Kr, whose isotopic abundances differ by 11 orders of magnitude. This scheme allows ATTA-3 to directly determine (super 81) Kr/Kr and (super 85) Kr/Kr ratios without other supplemental measurements. Combining the significant reduction in sample size with several advances in the measurement procedure, ATTA-3 represents the state-of-the-art instrument for routine analysis of these rare noble gas tracers for a wide range of earth science applications. More information regarding ATTA-3 is posted at http://www.phy.anl.gov/mep/atta/.

Because of its vast size and the potential for large regional flow systems to occur, the GAB has been considered an ideal basin to test emerging groundwater dating techniques such as Cl-36 and He-4. However both of these techniques are subjected to large degrees of uncertainty, as they require a detailed understanding of different sources and sinks of these two isotopes. Contrasting this Kr-81 is considered to be an ideal tracer as it contains only one source, the atmosphere with no or at most minimal sub surface production. Our study area is focused on the western margin of the GAB between the Finke River system in the Northern Territory and the iconic Dalhousie springs in South Australia. This represents the direction of groundwater flow from recharge to discharge through the Dalhousie spring complex. For the first time we have provided a comprehensive suite of analyse not only of Cl-36, He-4, C-14, Ar-39, stable isotopes of the water molecule and noble gases but also, Kr-85 and Kr-81. Our preliminary results indicate a spectrum of "tracer groundwater ages" ranging from modern as indicated by C-14 and Ar-39 up to hundreds of thousands of years as indicated by Kr-81, Cl-36 and He-4. We suggest that this groundwater flow transect may represent an ideal type section for understanding different isotope systematic in order to obtain a greater knowledge of regional groundwater flow.

The presence of complexing ligands significantly modifies the reduction potential of Hg (super II) , influencing its abiotic reduction. We tested the ability of magnetite, a biogenic mineral commonly found in subsurface environments, to reduce Hg (super II) complexed with carboxyl, chloride, and sulfhydryl ligands. These ligands are important constituents of subsurface geomedia. Since the binding constants of Hg-chloro complexes fall between -carboxyl and -sulfhydryl complexes, we further investigated the reduction of the Hg-chloride complex by magnetite containing varying Fe (super 2+) stoichiometry (the bulk Fe (super 2+) /Fe (super 3+) ratio, x). Hg (super II) adsorbed to Bacillus subtilis at high and low Hg:biomass ratios (corresponding to Hg complexation predominantly with carboxyl and sulfhydryl groups, respectively) was reacted with magnetite under anoxic conditions, and the solid phase was examined by Hg L (sub III) edge XAS. When Hg (super II) was bound predominantly to carboxyl groups, reduction of Hg (super II) to Hg (super 0) occurred within 2 h and 2 d at pH 6.5 and 5.0, respectively. When Hg (super II) was bound to sulfhydryl groups, it was not reduced by magnetite after 2 months of reaction at pH 6.5 or 5.0. In the presence of chloride, Hg (super II) was rapidly reduced to Hg (super 0) by stoichiometric (x=0.48) magnetite. The reduction of the Hg (super II) -chloride complex by more oxidized forms of magnetite (x=0.38 and 0.28) was kinetically hindered due to the formation of calomel (Hg (super I) (sub 2) Cl (sub 2) ) as a stable intermediate reaction product. However, reaction kinetics slowly progressed towards reduced Hg (super 0) after 4 months of reaction. These results suggest that the complexation of Hg (super II) with carboxyl, chloride, and sulfhydryl exhibits a progressively increased inhibition of the reduction of Hg (super II) to Hg (super 0) by magnetite. Since Hg is typically present in aquatic and terrestrial systems at low concentrations, binding of Hg (super II) to high affinity sulfhydryl sites on bacteria could have important implications for the potential reduction of Hg (super II) to Hg (super 0) and the overall mobility of Hg under Fe-reducing conditions.

However, these measurements do not provide for direct identification of the important site or sites involved in metal binding. Conversely, X-ray Absorption Spectroscopy (XAS) measurements can rigorously identify the important adsorption sites, but are less precise for determining reaction stoichiometry and stability constant values. We use these complementary techniques to elucidate the nature and extent of metal (Cd and Hg) adsorption onto typical Gram-positive and Gram-negative bacterial cell envelops. The bulk metal adsorption measurements indicate that adsorption can be reasonably explained by a 1:1 metal:site reaction stoichiometry over a wide range of metal loading conditions. However, 1:3 and 1:4 metal:site reaction stoichiometry was required to model the adsorption data at sub-ppm metal loading conditions. The SCM and XAS results are consistent with each other, indicating monodentate binding of metals onto both the carboxyl and the phosphoryl sites at higher metal loadings, and multi-dentate binding of metals onto sulfhydryl sites at the lowest metal loadings. The universal adsorption behavior of metal adsorption by biomass proposed by SCM was verified by XAS for bacterial consortium (containing diverse bacterial species) sampled from pristine environments. SCM and XAS have not only shown consistency for studying the metal-bacteria interactions as a function of pH and metal loadings, but also resulted in surprisingly precise match for determining the relative abundance of sulfhydryl sites on different bacterial species. However, SCM approach suffers from significant limitations under geochemical conditions favoring complete sorption of metals onto the biomass.

Calcite (104) cleavage surfaces were reacted with Pb-EDTA aqueous solution (0.09 mM Pb, 0.11 mM EDTA, 0.5 mM Ca, pH 8.35) at room temperature for times ranging from minutes to hours. Freshly cleaved calcite was placed in a flow-through cell, and reacted first with calcite-saturated solution and then Pb-EDTA solution, both at 0.3 mL/min. In situ synchrotron XR measurements revealed evidence for incorporation of Pb into the calcite lattice as well as the formation of cerrusite (PbCO3) with its (021) plane oriented parallel to calcite (104). The reacted calcite was further studied ex situ by atomic force microscopy (AFM) and optical microscopy. AFM imaging of the reacted surface outside the X-ray beam footprint showed narrow overgrowths atop steps and sparse precipitates on terraces (Fig. 1a). Different behavior was seen within the X-ray beam footprint; it contained abundant trapezoidal-and hexagonal-shaped precipitates oriented mainly along a single crystallographic direction, which is consistent with heteroepitaxial cerussite (021) overgrowths (Figs. 1b and 2). X-ray microfluorescence spectroscopy showed that the trapezoidal growth islands are Pb-rich. Features similar to those in Fig. 1a were observed by AFM in separate ex situ experiments without exposure to X-rays. These observations suggest that the X-ray beam enhanced precipitation even at bulk-undersaturated conditions with respect to cerussite (log SI = -2.3), possibly by photolytic destabilization of the Pb-EDTA2-solution complex.

To develop atomistic-informed constitutive models for the dissolution rate, we chose to study a well-characterized crystalline aluminosilicate - orthoclase - as initial model system. Time resolved X-ray reflectivity was previously used to obtain the face-specific dissolution rates of orthoclase (001) surfaces under a wide range of pH and temperature conditions. By studying elementary reactions of water and ions on orthoclase using first-principles methods, and combining these studies with Kinetic Monte Carlo (KMC) simulations, our goal is to develop fundamental models to understand the observed experimental dependence of dissolution rates on pH and temperature. We have performed first-principles-based modelling of surface site distribution as a function of pH and temperature on orthoclase surfaces of two different orientations (001) and (010). Differences in the surface species distribution are found for the two surfaces, suggesting different initial dissolution behavior. To evaluate reaction pathways, we have performed first-principles calculations of reaction barriers for water reactions with neutral, protonated and deprotonated sites of constituting network formers Si and Al (Fig. 1). The calculated reaction barriers together with the surface site distribution model are used to estimate the overall dissolution rates and compare with experimental values. Kinetic Monte Carlo studies were used to validate a phenomenological constitutive model. This work is aimed at better understanding of the dissolution behavior and development of predictive models for dissolution rates.

To understand the abiotic factors contributing to this process, we investigated the reduction of U (super VI) to U (super IV) by magnetite, a common rock forming mineral and product of microbial Fe (super III) respiration. U (super VI) reactivity with pure, stoichiometric magnetite (Fe (super II) Fe (super III) (sub 2) O (sub 4) ,Fe (super 2+) /Fe (super 3+) = 0.5) is compared to that with a series of oxidized (Fe (super 2+) /Fe (super 3+) or = 0.38) reduce U (super VI) to uraninite (U (super IV) O (sub 2) ) nanoparticles, whereas more oxidized magnetites (Fe (super 2+) /Fe (super 3+) < 0.38) adsorb U (super VI) as an inner-sphere complex without transferring electrons. The observed redox reactivity between magnetite and U (super VI) can be correlated with measured reduction potentials for magnetite and with published thermodynamic parameters for U (super IV) /U (super VI) redox couples [3]. Titanomagnetite nanoparticles with Ti formula contents up to x = 0.5 and Fe (super 2+) /Fe (super 3+) ratios between 0.5 and 1.2 can also reduce U (super VI) to U (super IV) . EXAFS spectra indicate that the reduced U (super IV) atoms are not incorporated in uraninite. The speciation of U (super IV) appears to be controlled by Ti-content and not by the Fe (super 2+) /Fe (super 3+) ratio, as the reduction of U (super VI) by partially oxidized x = 0.5 titanomagnetite results in the same non-uraninite U (super IV) species. This work highlights previously unexplored thermodynamic and geochemical factors that may influence the speciation and solubility of uranium in the subsurface. The observation of non-uraninite U (super IV) species in this study, as well as in carbonate and phosphate bearing systems in previous studies [4-6] suggests the need for a better understanding of the stability of reduced U (super IV) .

Sequence similarity search results encoded in an open, exchangeable format have the potential to limit the needs for computational reanalysis of these data sets. A prerequisite for sharing of similarity results is a common reference. Description: We introduce a mechanism for automatically maintaining a comprehensive, non-redundant protein database and for creating a quarterly release of this resource. In addition, we present tools for translating similarity searches into many annotation namespaces, e.g. KEGG or NCBI's GenBank.

These capabilities are expected to reduce the cost of nuclear reactor system and fuel form design cycles and improve future reactor designs for enhanced safety performance and reduced capital cost. A nuclear reactor modeling and simulation tool suite which realizes this vision, called SHARP(1), is being developed by Argonne National Laboratory in collaboration with Lawrence Livermore National Laboratory, Idaho National Laboratory, Oak Ridge National Laboratory, and other U.S. DOE and university contributors.

Combining with in situ XRD measurements, the Debye sound velocity of FP35 was determined from the low-energy region of the partial phonon density of states (DOS) obtained from NRIXS measurements in the pressure range of 70 to 140 GPa. In order to obtain an accurate description of the equation of state (EOS) for FP35, separate XRD measurements were performed up to 126 GPa at 300 K. A new spin crossover EOS was introduced and applied to the full P-V data set, resulting in a zero-pressure volume V (sub 0) = 77.24 + or - 0.17 Aa (super 3) , bulk modulus K (sub 0) = 159 + or - 8 GPa and its pressure-derivative K' (sub 0) = 4.12 + or - 0.42 for high-spin FP35 and K (sub 0,LS) = 72.9 + or - 1.3 Aa (super 3) , K (sub 0,LS) = 182 + or - 17 GPa with K' (sub 0,LS) fixed to 4 for low-spin FP35. The high-spin to low-spin transition occurs at 64 + or - 3 GPa. Using the spin crossover EOS and Debye sound velocity, we derived the shear (V (sub S) ) and compressional (V (sub P) ) velocities for FP35. Comparing our data with previous results on (Mg,Fe)O at similar pressures, we find that the addition of iron decreases both V (sub P) and V (sub S) , while elevating their ratio (V (sub P) /V (sub S) ). Small amounts (<10%) of low-spin FP35 mixed with silicates could explain moderate reductions in wave speeds near the core mantle boundary (CMB), while a larger amount of FP35 near the CMB would not allow a large structure to maintain neutral buoyancy.

In this paper we present an optimization analysis based on the implementation of a genetic algorithm (GA) subroutine to a numerical ray-tracing Monte Carlo model of an LSC, SIMSOLAR-P. The initial use of the GA implementation in SIMSOLAR-P is to find the optimal parameters of a hypothetical "perfect luminescent material" that obeys the Kennard Stepanov (K-S) thermodynamic relationship between emission and absorption. The optimization balances the efficiency losses in the wavelength shift and PV conversion with the efficiency losses due to re-scattering of light out of the collector. The theoretical limits of efficiency are provided for one, two and three layer configurations; the results show that a single layer configuration is far from optimal and adding a second layer in the LSC with wavelength shifted material in the near infrared region significantly increases the power output, while the gain in power by adding a third layer is relatively small. The results of this study provide a theoretical upper limit to the performance of an LSC and give guidance for the properties required for luminescent materials, such as quantum nanocrystals, to operate efficiently in planar LSC configurations.

As sites continue to be assessed, the topic of resilience is emerging as a necessary focus in risk management and infrastructure protection. Enhancing the resilience of critical infrastructures requires determining the ability of systems to withstand specific threats and return to normal operations after degradation. Thus, comprehensive consideration of all parts of infrastructure systems, from threats to consequences, is needed. The methodology must generate reproducible results that can support decision-making in risk management, disaster response, and business continuity. Argonne National Laboratory, in collaboration with the DHS Protective Security Coordination Division, has developed a comprehensive methodology that uses uniform and consistent data to develop a resilience index (RI). Using the RI to compare similar facilities can provide vital benefits to owners-operators as well as DHS.

Here, the design and experimental results of an in-situ synchrotron enhanced x-ray scanning tunneling microscope (SXSTM) system are presented. The system is designed to allow monochromatic synchrotron radiation to enter the chamber, illuminating the sample with x-ray radiation, while an insulator-coated tip (metallic tip apex open for tunneling, electron collection) is scanned over the surface. A unique feature of the SXSTM is the STM mount assembly, designed with a two free-flex pivot, providing an angular degree of freedom for the alignment of the tip and sample with respect to the incoming x-ray beam. The system designed successfully demonstrates the ability to resolve atomic-scale corrugations. In addition, experiments with synchrotron x-ray radiation validate the SXSTM system as an accurate analysis technique for the study of local magnetic and chemical properties on sample surfaces.

Because of extensive urban development in the past fifty years, this ecologically significant community type is highly degraded and fragmented. To conserve endangered CSS communities, monitoring internal conditions of communities is as crucial as monitoring distributions of the community type in the region. Vegetation type mapping and field sampling of individual plants provide ecologically meaningful information about CSS communities such as spatial distribution and species compositions, respectively. However, both approaches only provide spatially comprehensive information but no information about internal conditions or vice versa. Therefore, there is a need for monitoring variables which fill the information gap between vegetation type maps and field-based data. A number of field-based studies indicate that life-form fractional cover is an effective indicator of CSS community health and habitat quality for CSS-obligated species. This study investigates the effectiveness of remote sensing approaches for estimating fractional cover of true shrub, subshrub, herb, and bare ground in CSS communities of southern California. Combinations of four types of multispectral imagery ranging from 0.15m resolution scanned color infrared aerial photography to 10m resolution SPOT 5 multispectral imagery and three image processing models - per-pixel, object-based, and spectral mixture models - were tested. An object-based image analysis (OBIA) routine consistently yielded higher accuracy than other image processing methods for estimating all cover types. Life-form cover was reliably predicted, with error magnitudes as low as 2%. Subshrub and herb cover types required finer spatial resolution imagery for more accurate predictions than true shrub and bare ground types. Positioning of sampling grids had a substantial impact on the reliability of accuracy assessment, particularly for cover estimates predicted using multiple endmember spectral mixture analysis (MESMA) applied to SPOT imagery. Of the approaches tested in this study, OBIA using pansharpened QuickBird imagery is one of the most promising approaches because of its high accuracy and processing efficiency and should be tested for more heterogeneous CSS landscapes. MESMA applied to SPOT imagery should also be examined for effectiveness in estimating factional cover over more extensive habitat areas because of its low data cost and potential for conducting retrospective studies of vegetation community conditions.

It is found that an Avrami-Erofeyev type model, normally used in solid-gas systems, can be modified for this two-step reaction to describe the measured kinetics of hydrogen release and the observed double peaks in release rates. The kinetic model indicates that temperatures in excess of 200 degree C are needed for complete conversion (release of 2.35 H sub(2-equivalents) in a reasonably compact flow reactor with <20 s AB/IL residence time. A non-isothermal, plug flow reactor model indicates that heat transfer to ethylene glycol at 80 degree C alone is not sufficient to control the peak temperature to <250 degree C in the exothermic decomposition reaction. The peak temperature, however, can be controlled by partial recycling of the spent AB/IL mixture. The reactor can also be operated adiabatically to obtain complete conversion while limiting the peak temperature through recycle. In a flow reactor where the feed stream is heated by mixing with the recycle stream there is a minimum recycle ratio for complete conversion. This minimum recycle ratio is a function of the reactor outlet temperature, which is determined by heat transfer.)

SIMS lateral resolution has reached nearly equal 50 nm and useful yields are at most a few percent. We are completing construction of CHILI (the CHicago Instrument for Laser Ionization), a resonant ionization mass spectrometry (RIMS) nanobeam instrument designed for isotopic and chemical analysis at the few-nm scale with a useful yield of > or =35% [1]. CHILI is equipped with a COBRA-FIB high resolution liquid metal ion gun (LMIG) and an e-CLIPSE Plus field emission electron gun from Orsay Physics, each of which can be focused to <4 nm. The electron gun will be used for secondary electron imaging, as the built-in optical microscope is diffraction-limited to nearly equal 0.5 mu m. A piezoelectric stage capable of reproducible nm-scale motions and equipped with a sample holder that will accept a wide variety of sample mounts is operational. The flight tube for the time-of-flight mass spectrometer mounted vertically above the sample chamber; this assembly is mounted in the center of an H-shaped laser table equipped with active vibration cancellation devices. The table has been demonstrated to have a vertical vibrational amplitude of less than 0.2 nm. Resonant ionization will be done with six Ti:sapphire tunable solid state lasers pumped with three 40W Nd:YLF lasers, which will allow two to three elements to be analyzed simultaneously. Ion detection in existing RIMS instruments [2,3] is done with a microchannel plate with a single anode. Isotope ratio precision is limited by counting statistics, as no more than one ion of the most abundant isotope of an element can be counted for each pulse. CHILI will initially be equipped with such a detector, but we are developing a multianode detector to significantly improve the count-rate capability. CHILI reflects many recent developments in instrument design, and most technical properties are pushed towards their physical limits. CHILI will be applied to a multitude of cosmochemical problems such as analysis of cometary and contemporary interstellar dust from the Stardust mission, asteroidal dust from the Hayabusa mission, a wide variety of samples from meteorites and IDPs, and, in a few years, asteroidal samples returned by the OSIRIS-REx mission.

The most interesting of these isotopes from an AGB nucleosynthetic standpoint are the trace isotopes (super 54) Cr and (super 58) Fe, which are predicted to have deviations from average Solar System ratios of nearly equal 100ppm and >200ppm, respectively. The other isotopes of Cr and Fe are essentially unchanged by AGB stars, and are representative of the isotopic composition of the protostellar cloud from which the SiC grains formed. They are thus tracers of Galactic Chemical Evolution, and provide a benchmark for the isotopic composition of the galaxy some five to seven billion years ago. SiC grains were isolated from the Murchison meteorite using high purity reagents and techniques specifically designed to prevent contamination with terrestrial Cr and Fe. Grains from the 2-4 mu m size fraction were pressed into a high purity gold foil. Chromium and iron isotopic compositions were measured by Resonance Ionization Mass Spectrometry (RIMS) using new techniques specifically developed for high precision isotopic analysis of iron-peak elements. The Cr isotopic compositions of 19 grains form a distinct group. Several grains had resolvable (>2sigma ) (super 50) Cr and (super 53) Cr deficits ranging as low as -178ppm. The (super 54) Cr/ (super 52) Cr delta -values were all within 2sigma of the Solar System value, though most were slightly higher. The average delta -values for the grains were -45+ or -31ppm for (super 50) Cr, -37+ or -21ppm for (super 53) Cr, and +25+ or -26ppm for (super 54) Cr. Iron results are pending. Given that AGB stars change most Fe and Cr isotope ratios very little, and that these grains' progenitor stars formed from a few hundred million to about three billion years before the Solar System formed (assuming their initial masses were 1.5 - 3 solar masses), and that grain interstellar residence times are likely less than nearly equal 100 - 200 million years, the Fe and Cr isotopes in mainstream grains largely retain the composition of the interstellar medium from about 5 to 7.5 billion years ago. Comparing our data to predictions for Cr synthesis in Type II and Type Ia supernovae (the main producers of Cr) shows deviations from simple mixing lines (assuming appropriate metallicities and initial mass functions). The mixing model predicts greater deficits in (super 50) Cr and/or (super 53) Cr than is seen in the grains. In the case of (super 54) Cr, a 100ppm enhancement due to AGB nucleosynthesis nearly accounts for the deviation from the mixing line.

One of the alternatives considered in the PEIS involves development within identified solar energy zones (SEZs) that individually cover approximately 10 to 1,000 km (super 2) , located primarily in desert valleys of the Basin and Range physiographic region. Land-disturbing activities in these alluvium-filled valleys have the potential to adversely affect ephemeral streams with respect to their hydrologic, geomorphic, and ecologic functions. Regulation and management of ephemeral streams typically falls under the spectrum of federal, state, and local programs, but scientifically based guidelines for protecting ephemeral streams with respect to land-development activities are largely nonexistent. The PEIS analysis attempts to identify critical ephemeral streams by evaluating the integral functions of flood conveyance, sediment transport, groundwater recharge, and supporting ecological habitats. The initial approach to classifying critical ephemeral streams involved identifying large, erosional features using available flood hazards mapping, historical peak discharges, and aerial photographs. This approach identified ephemeral features not suitable for development (based primarily on the likelihood of damaging floods and debris flows) to address flood conveyance and sediment transport functions of ephemeral streams. Groundwater recharge and the maintenance of riparian vegetation and wildlife habitats are other functions of ephemeral streams. These functions are typically associated with headwater reaches rather than large-scale erosional features. Recognizing that integral functions of ephemeral streams occur over a range of spatial scales and are driven by varying climatic-hydrologic events, the PEIS analysis assesses ephemeral streams according to their position in the basin, stream order, and the recurrence intervals of runoff events in the basin. A key constraint on this approach is the lack of high-resolution hydrologic, geomorphic, and ecological data for ephemeral streams in remote desert basins of the southwest United States. Consultation with stakeholders and management agencies is an additional component to assist with our analysis where data limitations exist. Results from these analyses identify critical ephemeral stream reaches to be avoided during development activities based on a mix of quantitative and qualitative measures. Long-term monitoring of these systems is needed to assess the avoidance criteria and to help advance development of the tools needed to help manage and protect the integral functions of ephemeral stream networks in arid environments.

Placing constraints on the core's carbon content requires knowledge on the phase stability, density, and sound velocities of relevant iron-carbon alloys under the corresponding pressure and temperature conditions. Recent technological advances have opened new windows on viewing the structure and vibrational properties of iron-rich materials under megabar pressure and high temperature. Here we report new experimental results on the equations-of-state and phonon density-of-states of compressed Fe3C and Fe7C3 under core pressures and elevated temperatures. The measurements use specialized diamond-anvil cell designs and newly developed single-crystal X-ray diffraction (SXD) and nuclear resonant inelastic X-ray scattering (NRIXS) techniques. Our data reveal intriguing behavior of the two carbides under extreme conditions, including pressure-induced magnetic transitions, "invar-like" compressiblity, and significant phonon softening under high temperature. The results bear on the presence and role of carbon in the Earth's core.

Percolation of liquid iron-rich alloy through a crystalline silicate matrix has been suggested as a possible core formation mechanism, especially for the differentiation of planetesimals during the early history of our solar system, since radioactive decay of short-lived isotopes in the small accreting bodies cannot provide enough heat to form extensive melting (i.e. magma ocean). Previous experimental results looking at dihedral angles in silicate metal samples synthetized at elevated pressures and temperatures suggest that percolation is unlikely to be an efficient mechanism in our planet. However, experimental conditions in previous work have been limited in upper mantle conditions (<30GPa). Moreover the measurement of dihedral angles using transmission electron microscopy or backscattered electron microscopy may not generate satisfactory statistics. Nanoscale x-ray computed tomography (nanoXCT) has exciting potential as an accurate probe to study the 3D connectivity and permeability of core forming melts in crystalline silicates. Using a laser-heated diamond anvil cell, experimental conditions over the entire pressure-temperature range in the lower mantle can be accessed. In this study, we compressed and heated the mixture of iron-rich alloy + orthopyroxene, and then used a focused ion beam (FIB) to mill the quenched samples to extract a portion for nano-XCT. Pilot studies from our group using 3D nano XCT have demonstrated the ability to image the detailed morphology of the iron-alloy and silicates, along with details of Fe-FeS eutectic intergrowth patterns, which help to distinguish the relative Fe content in Fe and FeS. Data resulting from the combination of these techniques could improve our understanding of planetary core-forming processes.

Despite considerable study during the past three decades, the origin of the high-pressure cubic-rhombohedral transition in this fundamental material is still not fully understood. We applied a high-pressure nanoscale x-ray diffraction imaging technique to investigate Fe0.94O under pressure. The results reveal non-reflection (110) domain wall structures that form due to the rhombohedral distortion, which suggest the transition is ferroelectric in nature and originates from the defects intrinsic to the material. This conclusion is supported by first-principles density functional theory (DFT) calculations that consider the defects.

Knowing the elasticity of iron and its alloys is thus critical to understanding the physics and chemistry of the Earth's core. In particular, the alloying effects of light elements on the elasticity of iron are of great importance to establishing satisfactory geophysical and geochemical models of the Earth's core. For example, comparison between compressional wave velocity-density (Vp-rho ) relation of candidate iron-light element alloys and seismic velocity profiles at pressure-temperature (P-T) conditions relevant to the core provides a direct constraint on the composition of the Earth's core. According previous studies, different light elements can have distinct effects on the elasticity of iron under high P-T. It should be noted that high temperatures can also affect the Vp behavior of iron-light element alloys under the pressures. Thus the experimental Vp-rho results of iron alloys at simultaneous high P-T conditions are indispensable to establish a more reasonable composition model of the Earth's core. Here we have measured the Vp-rho relation of Fe-Si alloy under high pressures using in situ high-energy resolution inelastic X-ray scattering (HERIX) and X-ray diffraction in a diamond anvil cell (DAC). Compared with previous Vp studies on iron, these results allow us to derive the alloying effect of silicon on the Vp of hcp-Fe. Our data are also used to critically evaluate seismic and geochemical models of the core, providing new insights into understanding seismic observations and chemical composition of the Earth's inner core.

Quartz is composed solely of corner-sharing SiO4 silica tetrahedra, a primary building block of many of the Earth's crustal and mantle minerals, lunar and Martian minerals, and meteoritic minerals. Quartz is therefore an outstanding model material for investigating the response of this fundamental structural unit to changes in P, T, and x. These facts have spawned a vast literature of experimental and theoretical studies of quartz at ambient and non-ambient conditions. Investigations into the behavior of quartz at high pressure have revealed an anomalous distortion in the silicate tetrahedron with pressure not typically seen in other silicates. The tetrahedron assumes a very distinct geometry, becoming more like the Sommerville tetrahedron of O'Keeffe and Hyde (1996) as pressure increases. Traditionally, this distortion has been considered a compression mechanism for quartz, along with Si-O-Si angle-bending and a very small component of bond compression. However, tetrahedral volume decreases by only 1% between 0.59 GPa and 20.25 GPa, while unit cell volume decreases by 21%. Therefore, most of the compression in quartz is happening in tetrahedral voids, not in the silicate tetrahedron, and the distortion of the silicate tetrahedron may not be the direct consequence of decreasing volume in response to increasing pressure. The structure of quartz at high temperature and high pressure, including new structural refinements from synchrotron singe-crystal data collected to 20.25 GPa, is compared to the following three hypothetical quartz crystals: (1) Ideal quartz with perfectly regular tetrahedra and the same volume and Si-O-Si angle as its observed. (2) Model quartz with the same Si-O-Si angle and cell parameters as its observed equivalent, derived from ideal by altering the axial ratio. (3) BCC quartz with a perfectly body-centered cubic arrangement of oxygen anions and the same volume as its observed equivalent. The ideal quartz model presented in this talk verifies the rigid unit mode theory conclusion that there is no intrinsic geometric constraint that forces distortion in the tetrahedron as quartz compresses. A comparison of observed and ideal quartz shows that angle-bending alone compresses ideal quartz as effectively as reducing temperature and increasing pressure in observed quartz. This begs the question: why does the tetrahedron distort with pressure? Comparison of the new experimental data and data recorded in the literature for quartz with these hypothetical crystal structures shows that quartz becomes more ideal as temperature increases, more BCC as pressure increases, and that model quartz is a very good representation of observed quartz under all conditions. This is consistent with the hypothesis that quartz compresses through Si-O-Si angle-bending, which is resisted by anion-anion repulsion resulting in increasing distortion of the c / a axial ratio from ideal as temperature decreases and/or pressure increases. The anomalous tetrahedral distortion observed in quartz as pressure increases should not be considered a compression mechanism, and results from repulsive nonbonded oxygen-oxygen interactions.

Despite its abundance, the properties of orthopyroxene at high pressure remain ambiguous (e.g., Zhang et al. 2011; Jahn 2008; Kung et al. 2004). We explored select properties of a synthetic powdered orthoenstatite (Mg (sub 0.87) (super 57) Fe (sub 0.13) ) (sub 2) Si (sub 2) O (sub 6) sample by X-ray diffraction (XRD) and nuclear resonance inelastic X-ray scattering (NRIXS) as a function of pressure in a neon pressure medium at 300 K. The XRD measurements were carried out at beamline 12.2.2 of the Advanced Light Source (Berkeley, CA), and the sample was studied up to 34 GPa. NRIXS measurements were carried out at sector 3ID-B of the Advanced Photon Source (Chicago, IL) in the pressure range of 3 to 17 GPa. From the raw NRIXS data, the partial phonon density of states (DOS) was derived (e.g., Sturhahn 2004). The volume (or pressure) dependence of several properties, such as the Lamb-Mossbauer factor, mean force constant, specific heat, vibrational entropy, and vibrational kinetic energy were determined from the DOS. We will discuss our results from these combined studies and the implications for Earth's upper mantle.

However, little is known for the spin state of iron in melts in the mantle. We have measured the Mossbauer spectra of (Mg (sub 0.8) Fe (sub 0.2) )(Si (sub 0.9) Al (sub 0.1) )O (sub 3) glass up to 93 GPa at 300 K in the diamond-anvil cell at Sector 3 of the APS. At ambient conditions, 64% of iron in the glass has a high quadrupole splitting value (QS=2.2 mm/s) consistent with high-spin Fe (super 2+) and 36% has a low QS value (=0.7 mm/s) consistent with high-spin Fe (super 3+) . The ratio of high QS to low QS populations is unchanged by 6 GPa. The population of the low QS site increases rapidly from 34% to 57% between 6 and 32 GPa, followed by a more gradual increase to 68% between 32 and 93 GPa, indicating that 50% of Fe (super 2+) changes from high QS to low QS in the pressure range. According to recent first-principles calculations, low- or intermediate-spin Fe (super 2+) has QS=0.5 approximately 1.5 approximately mm/s which overlaps with the QS of high-spin Fe (super 3+) . Therefore, the increase in the low QS site population can be related to a decrease in the spin moment of 50% of Fe (super 2+) between 6 and 93 GPa. If our findings are applicable for silicate melts, the spin transition in silicate melts may occur over a much wider depth range (200-2500 km) starting at a much shallow depth (200 km) than those in perovskite and ferropericlase in the mantle.

However, it needs to be very careful when applying the control strategy if inequality state constraints are active because handling the state constraints is one of the difficult issues in optimal control problems. In contrast to HEVs, Plug-in Hybrid Electric Vehicles (PHEVs) possibly consume all of the available electric energy, and so the activation of the state constraint on minimum State of Charge (SOC) is, unfortunately, a very common control problem for PHEVs. This paper describes mathematical derivations for an additional condition necessary for the inequality state constraints and solves the problem with several control options. Whereas PMP-based control allows a unique solution for HEVs. this paper shows that the control idea based on PMP produces a number of alternative solutions for PHEVs. However, battery efficiencies can be considered to evaluate the optimality of each solution, and simulation results from several control options show that maximizing a blended-mode control is the best solution to saving fuel for PHEVs. In terms of performance, the results of applying blended-mode control are very close to those obtained by applying a global optimal solution obtained from Dynamic Programming (DP).

The effect of initial sulfate concentration on U(VI) reduction was also tested. Both oleate and EVO were effective electron donor sources for U(VI) reduction. Accumulation of acetate as a major product and the removal of aqueous U(VI) were observed and were associated with sulfate reduction. Both oleate and EVO supported U(VI) reduction but at slower rates with a comparable but slightly lower extent of reduction than ethanol. X-ray absorption near-edge spectroscopy (XANES) analysis confirmed reduction of U(VI) to U(IV). The extent of U(VI) reduction in solid phase was negatively influenced by aqueous calcium concentration. The majority of electrons of the three substrates were consumed by sulfate reduction, Fe(III) reduction, and methanogenesis. Initial U(VI) concentration in the aqueous phase increased with increased sulfate concentration (1 versus 5 mM), likely due to U(VI) desorption from the solid phase. At the higher initial sulfate concentration more U(VI) was reduced and fewer electrons were used in methanogenesis. Analysis of bacterial and archeal populations using 16S rRNA gene libraries showed a significant increase in Deltaproteobacteria after biostimulation. The microbial community structures developed with oleate and EVO were significantly distinct from those developed with ethanol. Bacteria similar to Desulforegula spp. was predominant for oleate and EVO degradation but were not observed in ethanol-amended microcosms. Known U(VI)-reducing bacteria in the microcosms amended with the three electron donor sources included iron(III) reducing Geobacter spp. but in lower abundances than sulfate-reducing Desulfovibrio spp. The test results were used for the design a field test by one-time injection of EVO to the subsurface for U(VI) reduction in Area 2 of the ORIFRC site.

Pilot-scale studies of in-situ U(VI) reduction were conducted at a site adjacent to the former S3 ponds (source zone) of the U.S. Department of Energy Oak Ridge Field Research Center, Oak Ridge, TN. The site contains uranium concentrations up to 800 mg/kg in soil and 250 mu M (60 mg/L) in groundwater. In field tests, flushing and pH adjustment decreased aqueous U concentrations by more than 1000 fold from 30-40 to nearly equal 1 mg/L. Ethanol addition stimulated microbial reduction of U(VI) and decreased U concentrations below the U.S. EPA maximum contaminant level for drinking water (30 ppb). U(VI) reduction was concomitant with iron(III)- and sulfate respiration. Spectroscopic analyses indicated sequential changes in the solid-associated uranium: U(VI) initially bound to mineral-surface and organic-bound complexes containing phosphate and carbonate, or as hydroxide and phosphate precipitates, was reduced mainly to a U(IV)-Fe complex. The U(IV) was stable under anaerobic conditions, but partially remobilized upon exposure to oxygen. In separate experiments, nitrate was injected into a reduced region of the subsurface containing previously immobilized U(IV). The nitrate was reduced to nitrite, ammonium, and nitrogen gas; sulfide levels decreased; and Fe(II) levels increased then deceased. Re-reduction of oxidized sediments released Fe(II) and soluble U(VI), suggesting that the decrease in soluble U during reoxidation was due to U(VI) sorption to Fe(III) oxides. Follow-up laboratory studies established that both biotically-generated hydrogen sulfide and soluble ferrous iron species reduce U(VI). For a sulfate-reducing bacterium isolated from the Oak Ridge site, microbially-generated sulfide could explain the observed rate of U(VI) reduction. Laboratory studies established that soluble Fe(II) was able to reduce soluble U(VI) at rapid rates when conditions were thermodynamically favorable, resulting in formation of U(IV)-Fe precipitate. Finally, U(IV) formed by sulfate- and iron-reducing enrichments was evaluated for re-oxidation. In a sulfate-reducing enrichment, oxygen oxidized and mobilized U(IV), but less mobilization occurred in the Fe(III)-reducing enrichment, and the mobilized U(VI) was ultimately removed from solution. In three-year batch microcosm experiments, uranium remained immobilized in re-oxidized sediment at pH 6.5-7 and DO 5-6 mg/L. Addition of nitrate did not mobilize uranium. The results suggest that long-term sequestration of uranium is feasible and may be achievable through sequential reduction and oxidation.

Understanding the impact of pore-scale environments (e.g. spatial heterogeneity, chemical gradients, and redox potential) is essential for modeling contaminant fate and transport in the subsurface. The driver for biogeochemical processes at the pore scale changes from macroscopic advection to microscale diffusion, and this has a significant effect on the retention of soluble, highly mobile contaminants such as U(VI). Here, etched-silicon microfluidic models with defined chemistry, mineralogy, microbiology, and flow regimes are used for the incremental development of complex microenvironments that approach real-world systems. We demonstrate the colonization of such pore spaces by an anaerobic Fe(III)-reducing bacterium, the enzymatic reduction of a bioavailable Fe(III) phase within this environment, and the subsequent effects of both oxidized and reduced Fe phases on uranium biogeochemistry under flow conditions using both X-ray Microprobe (XMP) and X-ray Absorption Spectroscopy (XAS). Precipitated Fe(III) phases within the microfluidic model were most effectively reduced in the presence of an electron shuttle (e.g. AQDS), with Fe(II) ions adsorbing onto mineral precipitates and surfaces. In the absence of Fe, U(VI) was effectively reduced by the microbial population to insoluble U(IV), which was precipitated in discrete regions associated within biomass. In the presence of both oxidized and reduced Fe phases however, differing effects were observed with regards to U behavior; oxidized U(VI) was frequently adsorbed to poorly crystalline Fe(III), and reduced U(IV) associated with more reduced regions of the microscale flow cell. In the future, the flexibility in the design of the microfluidic models, in combination with advanced characterization techniques, will allow us to further probe a range of pore-structures with distinctive physical, chemical and biological properties to provide a better understanding of biogeochemical redox processes occurring at the pore scale and their impact on contaminant transport.

The EVO injection took place in Area 2 of the IFRC located about 300 m downgradient of the former S-3 disposal ponds. Liquid wastes, disposed in the ponds from 1951 to 1983, were primarily composed of nitric acid, plating wastes containing various metals (Cr, Ni) radionuclides (U, Tc), inorganics (nitrate, sulfate) and organic contaminants (tetrachloroethylene, acetone). Prior pond closure in 1987, large volumes of waste fluids migrated into the subsurface, down Bear Creek Valley and into Bear Creek. Contaminants detected at Area 2 were transported through a high permeability gravelly fill that is considered a preferred transport pathway for U to Bear Creek. Groundwater in the gravelly fill is contaminated with U (1-3 mg/L), sulfate (95-130 mg/L), and nitrate (20-40 mg/L) and 500 mg/kg or higher U has been detected on the solid phase of the fill material. The objective of this study is to investigate the feasibility and long-term sustainability of U(VI) reduction and immobilization, and nitrate degradation in the high permeability, high flow gravel fill using EVO as the electron donor. A one-time EVO injection was conducted over a 2 hour period in the highly permeable gravel (hydraulic conductivity 0.08 cm/sec) in the well instrumented IFRC Area 2 field plot. Extensive monitoring of geochemical parameters, dissolved gases and microbial populations were conducted during the test. A bromide tracer test was conducted prior to the injection of the EVO to assess transport pathways and rates. Geochemical analysis of site groundwater demonstrated the sequential bioreduction of oxygen, nitrate, Mn(IV), Fe(III) and sulfate. Transient accumulation of acetate was observed as an intermediate in the oil degradation. Reduction and removal of U and nitrate from groundwater was observed in all wells in hydraulic connection to the injection wells after 2-4 weeks. U concentrations in groundwater were reduced to below 30 ppb (US EPA drinking water standard) at some well locations and nitrate was reduced to below detectable levels. Rebound of U in groundwater was observed together with the rebound of sulfate concentrations as the EVO was consumed. The flux of U and nitrate contamination from groundwater to the surface water receptor (Bear Creek) was significantly reduced by the EVO injection over a one year period. Uranium (VI) reduction to U(IV) in the field tests was confirmed by X-ray absorption near-edge spectroscopy (XANES) analysis. The reduced U(IV) was determined by X-ray absorption fine structure (XAFS) to be in an Fe-U complex, not uraninite. The activities of major Fe(III)- and sulfate-reducing bacteria with U(VI)-reducing capability as well as methanogens was stimulated after injection of the oil.

Yet, few students are able to experience research projects at national facilities due to limited accessibility caused in part by limited involvement in the local academic institution, constrained working areas at the experimental stations, and/or travel costs. We present a virtual and remote beam-line for deep Earth mineral physics studies using nuclear resonant and inelastic x-ray scattering methods at Sector 3 of the Advanced Photon Source at Argonne National Laboratory. Off-site students have the capability of controlling their measurements via secure internet connections and webcams. Students can access a "view only mode" for ease of interaction and safety-control. More experienced users have exclusive control of the experiment and can remotely change variables within the experimental setup.

Previous studies have shown that both aquifers are receiving modern recharge under the current drier climatic conditions. The validity of these advocated models was tested using geophysical (conventional Electrical Resistivity, [ER]) and isotopic (O, H) data, and estimates for modern recharge were obtained using continuous rainfall-runoff modeling over the period 1998-2007. First-order estimates of the average annual modern recharge for the NSS aquifer ( nearly equal 13.0 x 10 (super 6) m (super 3) /yr) and the shallow Alluvial aquifers in the Sinai Peninsula for the investigated watersheds (456 x 10 (super 6) m (super 3) /yr) and the shallow Alluvial aquifers in the Eastern Desert (147 x 10 (super 6) m (super 3) /yr) were computed using the SWAT (Soil Water Assessment Tool) model and readily available global remote sensing data sets (e.g., TRMM). Projections of climate change over North Africa from three of the leading general circulation models (GCMs) (GISS, GFDL, and UKMO) indicate a potentially high degree of vulnerability in the future precipitation amounts in Egypt. For each of the major watersheds and the Nubian Sandstone outcrops, we ran the calibrated model over the investigation period (1998-2007) using the obtained average annual precipitation and additional values of 10, 50, 100, and 150 mm. The SWAT model outputs were then used to extract relationships describing variations in runoff, recharge, and evaporation in relation to average annual precipitation amounts. Using developed tools on a web-based GIS interface we described these relationships under various climatic trends. Using a 10% decrease in rainfall in Egypt results in decreasing the average annual recharge to the shallow Alluvial aquifers in the Sinai Peninsula (384 x 10 (super 6) m (super 3) /yr) and in the Eastern Desert (111 x 10 (super 6) m (super 3) /yr). The observed differences between the watersheds in the partitioning of precipitation and in their response to increasing precipitation, is largely related to the variations in their lithologic characteristics. Findings bear on the sustainable exploitation of the Nubian Sandstone and shallow Alluvial aquifers, where the aquifer is being locally recharged, and on the exploitation of similar extensive aquifers largely recharged in previous wet climatic periods yet are still receiving modest modern meteoric contributions.

UCVM provides researchers with two new capabilities: (1) the ability to query Vp, Vs, and density from any standard regional California velocity model through a uniform interface, and (2) the ability to combine multiple velocity models into a single state-wide model. These features are crucial in order to support large-scale ground motion simulations and to facilitate improvements in the underlying velocity models. UCVM provides integrated support for the following standard velocity models: SCEC CVM-H, SCEC CVM-S and the CVM-SI variant, USGS Bay Area (cencalvm), Lin-Thurber Statewide, and other smaller regional models. New models may be easily incorporated as they become available. Two query interfaces are provided: a Linux command line program, and a C application programming interface (API). The C API query interface is simple, fully independent of any specific model, and MPI-friendly. Input coordinates are geographic longitude/latitude and the vertical coordinate may be either depth or elevation. Output parameters include Vp, Vs, and density along with the identity of the model from which these material properties were obtained. In addition to access to the standard models, UCVM also includes a high resolution statewide digital elevation model, Vs30 map, and an optional near-surface geo-technical layer (GTL) based on Ely's Vs30-derived GTL. The elevation and Vs30 information is bundled along with the returned Vp,Vs velocities and density, so that all relevant information is retrieved with a single query. When the GTL is enabled, it is blended with the underlying crustal velocity models along a configurable transition depth range with an interpolation function. Multiple, possibly overlapping, regional velocity models may be combined together into a single state-wide model. This is accomplished by tiling the regional models on top of one another in three dimensions in a researcher-specified order. No reconciliation is performed within overlapping model regions, although a post-processing tool is provided to perform a simple numerical smoothing. Lastly, a 3D region from a combined model may be extracted and exported into a CVM-Etree. This etree may then be queried by UCVM much like a standard velocity model but with less overhead and generally better performance due to the efficiency of the etree data structure.

CyberShake simulates between 6 and 32 slip distributions for each event at a slip sampling resolution of 1 km, and we calculate stress changes on fault surfaces at the same resolution, a level of detail which is unprecedented in studies of stress transfer and which allows us to study the way that variabilities in slip on the source can affect imparted stress changes. We find that earthquakes rupturing the southern San Andreas Fault generally decrease Coulomb stress on right-lateral faults in the Los Angeles Basin, while M>7 events on the San Jacinto, Elsinore, Newport-Inglewood and Palos Verdes Faults generally decrease stress on parallel right-lateral faults but increase Coulomb stress on the Mojave or San Bernardino sections of the San Andreas. Stress interactions between strike-slip and thrust faults and between the San Andreas and Garlock Faults depend on the rupture area of the source. Coulomb stress changes imparted by simulated SAF events to locations on the San Jacinto and Garlock Faults within approximately 8 km of the San Andreas appear to be influenced more by the nearby distribution of high and low slip on the San Andreas than by the overall slip distribution across the entire rupture. Using a simplified model, we calculate that an area of no slip surrounded by high slip on a rupture imparts strong Coulomb stress increases < or =7 km to either side of the source fault, possibly explaining the apparent approximately 8-km range of influence of local slip on the San Andreas. Additionally, we devise a method for evaluating uncertainty values in Coulomb stress changes caused by uncertainties in the strike, dip and rake of the receiver fault. These findings may be useful in understanding stress interactions between faults of different orientations and rakes, stress transfer and variability at short distances from the source fault, and applications of uncertainty values to Coulomb stress changes.

A paratransit bus consists of custom passenger compartments mounted onto separate cutaway chassis. The lack of dedicated national crashworthiness standards, along with different construction methods used by paratransit fleet manufacturers, can result in a wide variance of passenger compartment structural strength. In August 2007, the Florida Department of Transportation (FDOT), to ensure adequate crashworthiness performance, introduced a standard stipulating that newly acquired buses must be tested for rollover and side impact conditions. The rollover test is performed using a tilt table test according to UN-ECE Regulation 66. The side impact test involves the impact of a bus by a common sport utility vehicle or pickup truck. In the current study, an original finite element model of a paratransit bus was used in LS-DYNA registered simulations of both the rollover and the side impact testing procedures per FDOT standard. Using LS-OPT registered , a metamodel-based approach was used to perform multi-objective optimisation of the bus structure for the rollover and the side impact tests. The linear ANOVA and the Sobol's indices approach were used for sensitivity analysis. The structural components of the bus having the greatest influence on the bus performance in the simulated test scenarios were identified. The simulation results show that the original bus design would pass the FDOT testing procedure. However, appropriate redistribution of the mass can noticeably increase its strength for the side impact case.

Numerous processes in geodynamics fall into this category. For example, the evolution of viscous fluid flow and heat transport within the mantle (Stokes flow+energy conservation), the dynamics of melt migration (Stokes flow+Darcy flow+porosity evolution) and landscape evolution (Stokes+diffusion/advection over a surface). The development of software to numerically investigate processes that are described through the composition of different physics components are typically (a) designed for one particular set of physics and are never intended to be extended, or coupled to other processes (b) enforce that certain non-linearity's (or coupling) are explicitly removed from the system for reasons of computational efficiency, or due the lack of a robust non-linear solver (e.g. most models in the mantle convection community). We describe a software infrastructure which enables us to easily introduce new physics with minimal code modifications; tightly couple all physics without introducing splitting errors; exploit modern linear/non-linear solvers and permit the re-use of monolithic preconditioners for individual physics blocks (e.g. saddle point preconditioners for Stokes). Here we present a number of examples to illustrate the flexibility and importance of using this software infra-structure. Using the Stokes system as a prototype, we show results illustrating (i) visco-plastic shear banding experiments, (ii) how coupling Stokes flow with the evolution of the material coordinates can yield temporal stability in the free surface evolution and (iii) the discretisation error associated with decoupling Stokes equation from the heat transport equation in models of mantle convection with various rheologies.

The pulse power capability at low SOC is attractive for applications, such as plug-in hybrid electric vehicles (PHEVs), which require pulse power operation over the entire useable SOC window. A lithium- and manganese-rich transition-metal layered-oxide (LMR-NMC), also classified as a layered-layered oxide material, is blended with a lithium iron phosphate (LFP) to achieve a potentially low-cost, high-performance electrode. The LMR-NMC material provides high energy by delivering cathode material gravimetric energy densities greater than 890 Wh kg super(-1. The pulse power capability of this material at low SOC is greatly improved by incorporating a modest quantity of LFP. The LFP serves as an internal redox couple to charge and discharge the more rate-limited LMR-NMC material at moderate to low SOCs.)

Ceria (CeO sub(2)) was selected as a surrogate material for uranium dioxide (UO sub(2)) due to its many similar properties to UO sub(2). Ion beam energies were chosen such that both cavities and gas bubbles structures were induced by ion irradiations. The ion irradiation experiments were carried out at 600 degree C, at which temperature, cavity/gas bubble structures are believed to be immobile in this material. Lanthanum (La) was chosen as a dopant in CeO sub(2) to investigate the effect of impurities.

While deterministic approaches use a point forecast of wind power output, WPF uncertainty in the stochastic UC alternative is captured by a number of scenarios that include cross-temporal dependency. A comparison among a diversity of UC strategies (based on a set of realistic experiments) is presented. The results indicate that representing WPF uncertainty with wind power scenarios that rely on stochastic UC has advantages over deterministic approaches that mimic the classical models. Moreover, the stochastic model provides a rational and adaptive way to provide adequate spinning reserves at every hour, as opposed to increasing reserves to predefined, fixed margins that cannot account either for the system's costs or its assumed risks.

AN - 898206182; 21894944 AB - Galvanic replacement reaction between silver nanowires and an aqueous solution of HAuCl(4) has been successfully monitored in real time by using in situ transmission X-ray microscopy (TXM) in combination with a flow cell reactor. The in situ observations clearly show the morphological evolution of the solid silver nanowires to hollow gold nanotubes in the course of the reaction. Careful analysis of the images reveals that the galvanic replacement reaction on the silver nanowires involves multiple steps: (i) local initiation of pitting process; (ii) anisotropic etching of the silver nanowires and uniform deposition of the resulting gold atoms on the surfaces of the nanowires; and (iii) reconstruction of the nanotube walls via an Ostwald ripening process. The in situ TXM represents a promising approach for studying dynamic processes involved in the growth and chemical transformation of nanomaterials in solutions, in particular for nanostructures with dimensions larger than 50 nm.

X-ray emission spectroscopy and synchrotron Mossbauer spectroscopy reveal a rapid increase in the population of low-spin Fe (super 3+) in Fe (super 3+) , Al-bearing Pv over a narrow pressure range near 70 GPa, which is in sharp contrast with Al-free Fe (super 3+) -bearing Pv, where Fe (super 3+) undergoes a gradual spin transition, and with Al-free Fe (super 2+) -bearing Pv, where Fe (super 2+) does not become low spin. At low pressure, Fe (super 3+) and Al expand the perovskite lattice. However, near the pressure range of the abrupt increase in the low-spin population, the unit-cell volume of Fe (super 3+) , Al-bearing Pv becomes similar to that of Mg-endmember Pv, while those of Al-free Fe (super 3+) -bearing Pv and Al-free Fe (super 2+) -bearing Pv remain larger throughout the lower mantle. Consequently, Pv in Al-rich systems should have lower density in the shallow lower mantle but similar or greater density than Pv in pyrolite in the deep lower mantle, affecting the buoyancy and mechanical stability of heterogeneities. Although the Fe (super 3+) spin transition in Pv is unlikely to cause a seismic discontinuity at mantle temperatures, it may result in a large change in bulk sound speed at 1200-1800 km depth, such that a vertically extending structure with an elevated amount of Fe (super 3+) would generate slower and faster anomalies above and below the depth of the spin transition, respectively, relative to the surrounding mantle. This may have important implications for bulk sound speed anomalies observed at similar depths in seismic tomography studies.

In one experiment, NaCl was used as the pressure-transmitting medium (ambient pressure to 36 GPa), and in the other experiment, Ne surrounded the sample (4.1 to 26.8 GPa). The hyperfine parameters of the M1 and M2 sites at room pressure are in excellent agreement with previous literature values obtained using conventional Mossbauer spectroscopy and yield (Mg (sub 0.980) Fe (sub 0.020(5)) )(Mg (sub 0.760) Fe (sub 0.240) )Si (sub 2) O (sub 6) as the chemical formula. Analyses of both data sets reveal a change in the trend or discontinuity in the hyperfine parameters around 10 GPa, indicative of a transformation in orthopyroxene. However, the detailed behaviors of the iron sites with pressure appear to depend on the local stress conditions provided by the different pressure media. Our observations may help explain the reported variations in structural transition behavior for orthopyroxenes at high pressures.

In addition, long-period ( approximately 7-day) growth increments and annual growth increments have been observed in mammoth tusks. Such increments are used to determine individual age and season of death, and to provide temporal calibration for dentin compositional (e.g., stable isotope) series. Because the clarity of daily growth increments varies in thin sections imaged with conventional light microscopy, it has been difficult to verify the expected relationship between supposed daily and annual growth increments ( approximately 365 daily growth increments per annual increment) by direct counting. Alternatives to continuous accretion marked by daily increments include the possibility of periods of the year during which dentin accretion might have stopped, or the possibility that mammoths living in the arctic, like some other arctic vertebrates, exhibited a lack of circadian organization under the constant-light conditions of the arctic summer. Using synchrotron X-ray phase-contrast imaging, we are able to observe daily growth increments throughout sections of arctic mammoth tusks. Each daily increment is approximately 14 to 23 microns in thickness. There are about 365 "daily" increments within the "annual" growth increments that have been analyzed, suggesting that the observed features do represent daily and annual features. This also shows that dentin accretion is continuous throughout the year. Furthermore, the consistent formation of daily growth lines may indicate that arctic mammoths maintained circadian organization throughout the year despite the lack of 24-hour light/dark cues in the summer and winter. It is also possible that the analyzed annual growth increments were actually formed when these mammoths were living south of the Arctic Circle, exposed to year-round 24-hour light/dark cues.

Geostatistical methods provide a means for exploring that correlation structure and providing input to groundwater flow models. In this study, geostatistical methods were initially applied to nearly 300 km of drilling data derived from 11,000 private well drilling logs and 200 high-quality monitoring well logs. Analyses were focused on a 12,000-km (super 2) region in central Minnesota dominated by the Rainy, Superior, and Wadena lobes. The drilling data were categorized according to the logged sediment descriptions and analyzed in a variety of geomorphologically distinct zones using binary indicator geostatistics and transition probability geostatistics. A lack of stationarity was observed, consistent with a fundamental complexity of glacial depositional and erosional processes. Correlation generally varied as much between geographically distinct zones of like geomorphology as it did between zones of different geomorphology. These geostatistical methods were then tested to evaluate their relative effectiveness in supporting numerical flow modeling within a model domain containing the higher quality data. For the indicator variography and kriging approach, the flow model relied on the kriging results by grading the hydraulic conductivity (K) values between high and low values on the basis of the indicator output. Calibration was performed by systematic testing of various plausible end members of the K range. The transition probability runs were calibrated by stochastic inverse modeling. A baseline single-K analysis was also performed and calibrated through inverse modeling. Resulting K values from all four approaches were comparable, with the indicator kriging providing a very slight edge in terms of the calculated errors at calibration targets. The modeling suggests that in complex glaciated terrain, in which lateral correlation of hydrostratigraphic units is small relative to grid spacing and drilling data spacing, a single-K model provides a suitable approach to determining regional groundwater flow, despite the large contrasts in K prevalent in glacial drift materials.

Several previous studies have shown that CaCO (sub 3) + FeO + H (sub 2) O and similar reactions will produce methane at a wide variety of pressures, but there are outstanding questions regarding the potential role played by interactions with the gasket, and the amount of methane produced tends to be low. Here we have attempted to increase the methane yield by utilizing Fe metal, rather than FeO, and we have incorporated Au-lined gaskets to avoid potential interactions with the gasket. As expected, the amount of methane produced appears to be substantially increased as indicated by the relative intensity of the C-H stretching vibration in Raman measurements. We have also used synchrotron X-ray diffraction to examine crystalline phases upon temperature quench and after the samples have been decompressed to ambient pressure. Notably, the diffraction data from laser-heated samples is surprisingly complex, with closely spaced regions of the sample producing dramatically different diffraction patterns. Specifically, Fe, FeO and Fe (sub 3) O (sub 4) can be found in close proximity, in addition to unreacted CaCO (sub 3) and newly formed Ca(OH) (sub 2) . Furthermore, some diffraction patterns contain peaks from phases that we have been unable to identify, but we suspect these are produced by obscure Fe-Ca oxides. Accordingly, it is clear that laser-heated samples possess dramatic chemical variation as a result of steep temperature gradients, and we are unable to make a definitive determination of the methane-forming reaction. Nevertheless, we observe very strong methane formation at pressures ranging from 2-10 GPa and temperatures ranging from 1,000-2,500 K, and it is clear that catalytic reactions with the gasket are not necessary for these reactions to proceed.

The 2008 Yucca Mountain TSPA represented the culmination of more than two decades of advances both in underlying scientific understanding of the site and its engineered barrier systems, and in the application of probabilistic risk assessment methods to the long-term behavior of geologic repositories. The probabilistic estimates of million-year annual radiation doses to hypothetical humans living near the site considered a full range of uncertainties in the performance of natural and engineered systems and the consequences of unlikely disruptive events, as required by NRC regulations, and represented the most complete and detailed development to date of a system-level modeling approach adopted in various forms by most repository programs worldwide. Although the details of the 2008 TSPA were unavoidably site-specific and cannot be readily transferred to other potential disposal concepts, the approach remains broadly applicable and is likely to be an important part of the site selection, characterization, and licensing processes as the United States repository program moves forward. The Department of Energy's Used Fuel Disposition Campaign (within the Office of Nuclear Energy) is currently using simplified modeling tools to evaluate the potential performance of generic disposal concepts including mined repositories in crystalline rocks, clay/shale rocks, and salt, as well as deep boreholes in crystalline rocks. Although greatly simplified by necessity to apply to generic concepts, these performance assessment models build on the insights gained from the Yucca Mountain TSPA and other similar analyses in the US and internationally.

Here we show that the addition of 25% Fe in MgSiO (sub 3) perovskite increases its density and bulk sound velocity (V (sub phi ) ) by 4-6% and 6-7%, respectively, at lower-mantle pressures. Based on concurrent synchrotron X-ray emission and Mossbauer spectroscopic studies of the samples, the increase in V (sub phi ) and density can be explained by the occurrence of the low-spin Fe (super 3+) and the extremely high-quadrupole component of Fe (super 2+) . Combining these experimental results with thermodynamic modeling, our results indicate that iron-rich perovskite can produce an increase in density and a value of V (sub phi ) that is compatible with seismic observations of reduced shear-wave velocity in regions interpreted as dense, stiff piles in the lower mantle. Therefore, the existence of Fe-rich perovskite in the lower mantle may help elucidate the cause of the lower-mantle large low-shear-velocity provinces (LLSVPs) where enhanced density and V (sub phi ) are seismically observed to anti-correlate with the reduced shear wave velocity.

In this study, we report the first experimental measurements of phonon density of states, sound velocities, and Debye temperatures of Fe (sub 3) C up to 47 GPa and 1450 K using the nuclear resonant inelastic X-ray scattering (NRIXS) method in a laser-heated diamond anvil cell. Within the investigated pressure and temperature range, the effect of temperature on compressional velocity v (sub p) falls within the measurement uncertainties. The shear velocity v (sub s) decreases with increasing temperature in a non-linear fashion: at approximately 15 GPa, v (sub s) decreases by approximately 12% between 300 K and 740 K; at approximately 46 GPa, temperature produces a approximately 5% reduction between 300 and 960 K and a approximately 6% further reduction between 960 K and 1370-1450 K. The high-temperature v (sub s) of Fe (sub 3) C deviates from Birch's law behavior toward smaller values, potentially matching the anomalously low v (sub s) in the inner core under the relevant pressure and temperature conditions. Our results support Fe (sub 3) C as a major component of the inner core.

From each measured phonon DOS, we determined the vibrational free energy (F (sub vib) ) and mean-square displacement of atoms, . The volume dependence of F (sub vib) is directly related to the vibrational thermal pressure, which we combine with previously reported theoretical values for the electronic and anharmonic thermal pressures to find the total thermal pressure (P (sub th) ). In addition, we obtained the shape of epsilon -Fe's melting curve from the volume dependence of our , and anchored it with an experimentally determined melting point to obtain the high-pressure melting behavior of epsilon -Fe. Considering thermal pressure and anharmonic effects, we found epsilon -Fe's melting temperature at the pressure of Earth's core-mantle boundary (P=135 GPa) to be 3500+ or -100 K. Extrapolating our melting curve to the pressure of the inner-core boundary (ICB, P=330 GPa), where Earth's solid inner-core and liquid outer-core are in contact, we determined a melting temperature for epsilon -Fe of 5600+ or -200 K. Finally, combining this temperature constraint with our P (sub th) , we determined the density of epsilon -Fe under ICB conditions to be 13.50+ or -0.03 g/cm (super 3) , which is 5.5+ or -0.2% higher than the seismically inferred density at the ICB.

The authors present the effect of using 802.11aab/g wireless technology on real-time traffic surveillance systems. Although numerous studies have focused on studying the quality requirements for video streaming using a simulation environment, there is limited information on such performance in a real world environment. This study analyzed key video quality parameters, including packet jitter and packet rate, suggesting necessary guidelines for the transportation agency personnel to use when evaluating and selecting surveillance and communication tools. Study of the packet jitter showed that jitter and skipped video are strongly correlated with one another. Moreover, tolerated jitter ranges were identified that would ensure smooth traffic surveillance video. Findings indicated that to avoid jitter-related problems and to minimize the discontinuity of surveillance video, a 1-s play-out buffer size should be added to traffic surveillance communication systems. Analysis of packet rate suggested that an average value of 23aapackets/s can ensure smooth video continuity for traffic surveillance applications. Further analysis of multiple surveillance videos streaming simultaneously revealed the importance of knowing the available bandwidth for video transmission. Multiple video streaming over a wireless network indicated that the available bandwidth plays an important role in deciding the perceptual quality of the video.

AN - 883008267; 21714495 AB - Silver metal nanoparticle (NP) enhanced fluorescence is investigated in thin films of cyanobacterial Photosystem I trimer complexes (PSI) by correlating confocal laser scanning microscopy, dark-field imaging, and fluorescence lifetime measurements. PSI represents an interesting light-harvesting complex with a 20 nm diameter that is not uniformly contained within the surface-localized plasmon field of the NPs. With weak far-field illumination, 5- to 20-fold fluorescence enhancement is observed for PSI complexes adjacent to NPs, arising from efficient nanoparticle light collection and subsequent localized, surface plasmon excitation of PSI. Enhanced PSI fluorescence is detected most prominently near "rafts" of aggregated NPs that more completely fill the confocal field of view. These results demonstrate opportunities to probe energy transfer within photosynthetic complexes using plasmonic excitation and to design nanostructures for optimizing artificial light-harvesting systems.

However, in some bacterial and fungal species alternative routes of d-galactose assimilation have been identified. In the so-called De Ley-Doudoroff pathway, d-galactose is metabolized into pyruvate and d-glyceraldehyde 3-phosphate in five consecutive reactions carried out by specific enzymes. The penultimate step in this pathway involves the phosphorylation of 2-oxo-3-deoxygalactonate to 2-oxo-3-deoxygalactonate 6-phosphate catalyzed by 2-oxo-3-deoxygalactonate kinase, with ATP serving as a phosphoryl-group donor. Here, a crystal structure of 2-oxo-3-deoxygalactonate kinase from Klebsiella pneumoniae determined at 2.1Aa resolution is reported, the first structure of an enzyme from the De Ley-Doudoroff pathway. Structural comparison indicates that the enzyme belongs to the ASKHA (acetate and sugar kinases/hsc70/actin) family of phosphotransferases. The protein is composed of two alpha / beta domains, each of which contains a core common to all family members. Additional elements introduced between conserved structural motifs define the unique features of 2-oxo-3-deoxygalactonate kinase and possibly determine the biological function of the protein.

Companion adsorption experiments were also conducted for comparison. The macroscopic chemical and near atomic scale HRTEM data supplemented our molecule scale analysis with EXAFS (Kelly et al., 2008). Coprecipitation of Pb (super 2+) with ferric oxyhydroxides occurred at approximately pH 4 and is more efficient than adsorption in removing Pb (super 2+) from aqueous solutions at similar sorbate/sorbent ratios and pH. X-ray Diffraction (XRD) shows peaks of lepidocrocite and two additional broad peaks similar to fine particles of 2-line ferrihydrite (2LFh). HRTEM of the Pb-Fe coprecipitates shows a mixture of 2-6 nm diameter spheres and 8-20 by 200-300 nm needles, both uniformly distributed with Pb (super 2+) . Geochemical modeling shows that surface complexation models fit the experimental data of low Pb:Fe ratios when a high site density is used. Desorption experiments show that more Pb (super 2+) was released from loaded sorbents collected from adsorption experiments than from Pb to Fe coprecipitates at dilute EDTA concentrations. Desorbed Pb (super 2+) versus dissolved Fe (super 3+) data show a linear relationship for coprecipitation (CPT) desorption experiments but a parabolic relationship for adsorption (ADS) experiments. Based on these results, we hypothesize that Pb (super 2+) was first adsorbed onto the nanometer-sized, metastable, iron oxyhydroxide polymers of 2LFh with domain size of 2-3 nm. As these nano-particles assembled into larger particles, some Pb (super 2+) was trapped in the iron oxyhydroxide structure and re-arranged to form solid solutions. Therefore, the CPT contact method produced more efficient removal of Pb (super 2+) than the adsorption contact method, and Pb (super 2+) bound in CPT solids represent a more stable sequestration of Pb (super 2+) in the environment than Pb (super 2+) adsorbed on iron oxyhydroxide surfaces.

AN - 880716396; 21664641 AB - Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a potential human carcinogen, and its contamination of subsurface environments is a significant threat to public health. This study investigated abiotic and biological degradation of RDX in contaminated aquifer material. Anoxic batch systems were started with and without pre-aeration of aquifer material to distinguish initial biological RDX reduction from abiotic RDX reduction. Aerating the sediment eliminated chemical reductants in the native aquifer sediment, primarily Fe(II) sorbed to mineral surfaces. RDX (50 μM) was completely reduced and transformed to ring cleavage products when excess concentrations (2mM) of acetate or lactate were provided as the electron donor for aerated sediment. RDX was reduced concurrently with Fe(III) when acetate was provided, while RDX, Fe(III), and sulfate were reduced simultaneously with lactate amendment. Betaproteobacteria were the dominant microorganisms associated with RDX and Fe(III)/sulfate reduction. In particular, Rhodoferax spp. increased from 21% to 35% and from 28% to 60% after biostimulation by acetate and lactate, respectively. Rarefaction analyses demonstrated that microbial diversity decreased in electron-donor-amended systems with active RDX degradation. Although significant amounts of Fe(III) and/or sulfate were reduced after biostimulation, solid-phase reactive minerals such as magnetite or ferrous sulfides were not observed, suggesting that RDX reduction in the aquifer sediment is due to Fe(II) adsorbed to solid surfaces as a result of Fe(III)-reducing microbial activity. These results suggest that both biotic and abiotic processes play an important role in RDX reduction under in situ conditions.

In this study, cracking susceptibility of austenitic stainless steels was investigated by using slow strain rate tensile (SSRT) tests in a simulated pressurized water reactor (PWR) environment. The specimens were irradiated to 5, 10, and 48 dpa in the BOR60 reactor at 320 degree C. The SSRT results showed that yield strength was increased significantly in irradiated specimens while ductility and strain hardening capability were decreased. Irradiation hardening was found to be saturated below 10 dpa. The irradiated yield strength of cold-worked specimens was higher than that of solution-annealed specimens. Fractographic examinations were also performed on the tested specimens, and the dominant fracture morphology was ductile dimples. Intergranular cracking was rarely seen on the fracture surface. Transgranular cleavage cracking, however, was found more frequently on the specimen tested in simulated PWR environment.

In low-DO environments, crack growth rate (CGR) is significantly lower than that in high-DO environment. A strong dependence of CGR on corrosion potential has also been seen in irradiated SSs. While it has been shown that reducing the potential reduced the CGRs of irradiated SSs, some high-dose specimens have shown elevated CGRs even in low potential environments. Thus, it is not clear how irradiation affects the dependence of CGR on corrosion potential. In this study, a disk-shaped compact tension specimen of Type 316 SS was tested in low-DO environment. The specimen was irradiated in the BOR-60 reactor to 5 dpa at 320 degree C. Postirradiation CGR and fracture toughness tests were performed. The effect of unloading on crack growth behavior in low-DO environment is discussed.

The environmental enhancement of cyclic CGRs for Alloy 690 HAZ was comparable to that measured for the same alloy in the as-received condition. The two Alloy 690 HAZ samples tested exhibited maximum SCC CGR rates of 10-11 m/s in the simulated PWR environment at 320 degree C, however, on average, these rates are similar or only slightly higher than those for the as-received alloy.

Compact tension specimens were fabricated with the notch in Alloy 182 and oriented towards the WOL, and tested in a simulated PWR environment. The first such test revealed that the SCC rates in Alloy 182 were found to decrease by an order of magnitude ahead of the interface, and that the crack advanced from Alloy 182 into Alloy 52M. The post test examination found that crack branching occurred at the interface between the two allows. Growth in Alloy 52M along the interface appears severe, approx. 10-10 m/s. While for the most part (70%) the crack propagated along the interface, SCC cracking was also found to extend into Alloy 52M along the original direction. This cracking is substantial, yielding SCC rates of 10-11 m/s.

In order to meet the objective, specimens made from a laboratory-prepared Alloy 152 double-J weld in the as-welded condition were tested. For the SCC CGR measurements, the specimens were pre-cracked under cyclic loading in a primary water environment, and the cyclic CGRs were monitored to determine the transition from the fatigue transgranular fracture mode to the intergranular SCC fracture mode. The environmental enhancement of cyclic CGRs for Alloy 152 was minimal; nevertheless, the transition from transgranular to intergranular cracking was successful. Weld samples tested from the single heat of Alloy 152 exhibited SCC CGR rates of 10-11 m/s in the simulated PWR environment at 320 degree C, which was only about an order of magnitude lower than typical for Alloy 182.

However, difficulties with reprocessing have rendered this choice inappropriate, leading to the need to study alternative elements. In this work, we discuss the results of an atomistic modeling effort which allows for the systematic study of several possible alloying additions. Based on the behavior observed in the phase diagrams, beryllium or bismuth additions suggest themselves as possible options to replace Si. The results of temperature-dependent simulations using the Bozzolo-Ferrante-Smith (BFS) method for the energetics for varying concentrations of either element are shown, indicating that Be could have a substantial effect in stopping Al interdiffusion, while Bi does not. Details of the calculations and the dependence of the role of each alloying addition as a function of temperature and concentration (of beryllium or bismuth in Al) are shown.

Results for the gamma U- beta Zr solid solution are discussed, including the behavior of the lattice parameter and coefficient of thermal expansion as a function of concentration and temperature. Output from these calculations is used to study the surface structure of gamma U- beta Zr for different crystallographic orientations, determining the concentration profiles, surface energy, and segregation behavior. The analysis is completed with simulations of the deposition of Fe, Ni and Cr on U-Zr substrates with varying Zr concentration. All results are discussed and interpreted by means of the concepts of strain and chemical energy underlying the BFS method, thus obtaining a simple explanation for the observed Zr segregation and its influence in allowing for cladding elements diffusion into the U-Zr fuel.

In this study, two OTM materials, La sub(0.7Sr) sub(0).3Cu sub(0.2Fe) sub(0).8O sub(3-[delta] (LSCF) and BaFe) sub(0).9Zr sub(0.1O) sub(3)-[delta] (BFZ), were prepared by a conventional solid-state technique. In tests with an LSCF thin-film tube (thickness [asymptotic to]30 [micro]m) as an OTM, hydrogen was produced by flowing simulated product streams from coal gasification on one side of the OTM and steam on the other side. In this method, the coal gas on the oxygen-permeate side drives the removal of oxygen from the other hydrogen-generation side of the OTM, where hydrogen and oxygen are produced by water splitting. With CO (99.5% purity) flowing on the oxygen-permeate side, the hydrogen production rate of the LSCF tube was measured to be [asymptotic to]19.6 cm[super]3/min at 900 [deg]C, indicating that hydrogen can be produced at a significant rate by using product streams from coal gasification. Concentration polarization effects were found to lower the hydrogen production rate of the LSCF thin-film tube at high temperatures. This process also yields a CO sub(2-rich product stream that is ready for sequestration. The other candidate OTM material, BFZ, was tested by measuring its oxygen-permeation flux, DC conductivity, and hydrogen production, and by evaluating its microstructure. The dependences of the hydrogen production rate of BFZ disks (thickness, [asymptotic to]1.6 mm) on water partial pressure and temperature were determined while flowing 80% CO) sub(2)/He over a graphite rod on the oxygen-permeate side and humidified N sub(2 on the hydrogen-generation side.

In another, slow pressure increase experiment, the monoclinic high-pressure phase-II was observed to form at nearly equal 1.8 GPa, in agreement with earlier in situ studies, and its crystal structure has been unambiguously determined. Single-crystal data have been used to refine the structure models of both phases over the range of pressure up to the threshold of formation of cristobalite X-I at nearly equal 12 GPa, providing important constraints on the feasibility of the two competing silica densification models proposed in the literature, based on quantum mechanical calculations. Preliminary diffraction data obtained for cristobalite X-I reveal a monoclinic unit cell that contradicts the currently assumed model.

While this is largely true, we show using the Sinai Peninsula as our test site that the aquifer is locally receiving modern recharge under the current dry climatic conditions. The validity of the advocated model was tested using geophysical (conventional electrical resistivity [ER]) and isotopic (O, H) data, and estimates for modern recharge were obtained using continuous rainfall-runoff modeling over the period 1998-2007. Interpretations of ER profiles are consistent with the presence of unconfined NSS aquifers flooring recharge areas at the foothills of the crystalline basement in Sinai at Baraga (thickness: 20 to >188 m; resistivity: 16-130 Omega m) and Zalaga (thickness: 27 to >115 m; resistivity: 3-202 Omega m). The isotopic composition (delta D: -22.7 to -32.8 ppm; delta (super 18) O: -4.47 to -5.22 ppm) of groundwater samples from wells tapping the NSS aquifer underlying recharge areas is consistent with mixing between two endmembers: (1) fossil groundwater with isotopic compositions similar to those of the Western Desert NSS aquifer (delta D: -72 to -81 ppm; delta (super 18) O: -10.6 to -11.9 ppm), and (2) average modern meteoric precipitation (delta D: -9.84 ppm; delta (super 18) O: -3.48 ppm) in Sinai, with the latter endmember being the dominant component. A first-order estimate for the average annual modern recharge for the NSS aquifer was assessed at approximately 13.0X10 (super 6) m (super 3) /yr using the SWAT (Soil Water Assessment Tool) model. Findings bear on the sustainable exploitation of the NSS aquifer, where the aquifer is being locally recharged, and on the exploitation of similar extensive aquifers that were largely recharged in previous wet climatic periods but are still receiving modest modern meteoric contributions.

A parameter optimization method based on the nonlinear Levenberg-Marquardt algorithm is used. The mmW sensor works at 94 GHz and can detect the vital signs of a human subject from a few to tens of meters away. The reflected mmW signal is typically affected by respiration, body movement, background noise, and electronic system noise. Processing of the mmW radar signal is, thus, necessary to obtain the true HR. The down-converted received signal in this case consists of both the real part (I-branch) and the imaginary part (Q-branch), which can be considered as the cosine and sine of the received phase of the HR signal. Instead of fitting the converted phase angle signal, the method directly fits the real and imaginary parts of the HR signal, which circumvents the need for phase unwrapping. This is particularly useful when the SNR is low. Also, the method identifies both beat-to-beat HR and individual heartbeat magnitude, which is valuable for some medical diagnosis applications. The mean HR here is compared to that obtained using the discrete Fourier transform.

The compressibility of this high-silica-activity phase D (Mg (sub 1.0) Si (sub 1.7) H (sub 3.0) O (sub 6) ) has been measured up to 55.8 GPa at ambient temperature by powder X-ray diffraction. The volume (V) decreases smoothly with increasing pressure up to 40 GPa, consistent with the results reported in earlier studies. However, a kink is observed in the trend of V versus pressure above approximately 40 GPa, reflecting a change in the compression behavior. The data to 30 GPa fit well to a third-order Birch-Murnaghan equation of state (EoS), yielding V (sub o) = 85.1 + or - 0.2 Aa (super 3) ; K (sub o) = 167.9 + or - 8.6 GPa; and K' (sub o) = 4.3 + or - 0.5, similar to results for Fe-Al-free phase D reported by Frost and Fei (1999). However, these parameters are larger than those reported for Fe-Al-bearing phase D and for Fe-Al-free phase D. The abnormal volume change in this study may be attributed to the reported hydrogen bond symmetrization in phase D. Fitting a third-order Birch-Murnaghan EoS to the data below 30 GPa yields a bulk modulus K (sub o) = 173 (2) GPa for the hydrogen-off-centered (HOC) phase and K (sub o) = 212 (15) GPa for the data above 40 GPa for the hydrogen-centered (HC) phase, assuming K' (sub o) is 4. The calculated bulk modulus K (sub o) of the HC phase is 18% larger than the bulk modulus K (sub o) of the HOC phase.

Iron-bearing phases are the most important redox-active minerals in nature and the complex chemistry of these materials exemplifies the challenges in understanding solid phase redox reactions. For example, following the exposure of ferric iron (Fe (super 3+) ) (oxyhydr)oxides to reducing agents, interfacial electron transfer (ET) can lead to several transformation pathways including release of soluble ferrous iron (Fe (super 2+) ) (dissolution), formation of alternative ferric or mixed valence phases (transformation), or particle growth. Understanding and predicting such redox processes will require the application of time-resolved methods capable of observing the intermediate species that control reaction path. We have applied an optical-pump-X-ray-probe method with subnanosecond time resolution to study the fate of ferrous iron sites formed by electron injection at the surface of three phases of ferric iron (oxyhydr)oxides. We used this approach, combined with conventional kinetics studies, to distinguish the timescales for the elementary redox processes occurring during the reductive dissolution of 6-line ferrihydrite, maghemite and hematite nanoparticles. For each phase we quantified the rates of Fe-to-Fe electron hopping, the rates of interfacial electron transfer, the lifetime of kinetic electron trapping within the nanoparticles, and the rates of the full reaction including ferrous iron release into solution. Comparison of these rates which span from the nanosecond to the second scale reveal new insights into the electronic and structural factors controlling the redox reactivity of these phases.

The monovalent anion Tc(VII)O (sub 4) (super -) (pertechnetate) is subject to subsurface migration but Tc is considerably less soluble in its most reduced form, Tc(IV)O (sub 2) . Reduction can be catalyzed directly by a range of anaerobic microorganisms but also indirectly by products of microbial metabolism including ferrous iron and sulfide. We have investigated Tc(VII) reduction reactions in Hanford subsurface sediments and in well-defined model systems that include metal-reducing microorganisms and Fe-bearing minerals to explore speciation effects on reaction rates and Tc endproducts. In Hanford sediments collected from anoxic regions of the subsurface or oxic sediments subjected to microbial reduction, 2 X 10 (super -5) M (20 mM) aqueous Tc(VII) was reduced to below the detection limit (3.98 X10 (super -9) M) over times ranging from days to months. The rate and extent of reduction was dependent on sediment source, Fe(II) speciation, and sulfide concentration. X-ray microprobe analyses, including fluorescence mapping, elemental multichannel analysis, and micro-diffraction, were used to deduce Tc speciation and mineralogic association in the various sediments. In bioreduced Hanford formation sediments Tc(IV) was associated with phyllosilicates (mica), as indicated by associated Fe and Rb (analogous to K) signals. X-ray absorption spectroscopy (XAS) revealed the presence of Tc(IV)O (sub 2) and Fe(III)- associated Tc(IV). Tc(VII) was also reduced by sediment-associated biogenic sulfide; Tc-S bonding at the nearest coordination environment around absorber Tc atom was revealed by XAS. These results indicate that Fe(II) associated with Hanford subsurface sediments can be a facile reductant of Tc(VII)O (sub 4) (super -) and that the rate of reduction and nature of Tc end product is a function of Fe(II) speciation. These results have implications for far-field (super 99) Tc migration at Hanford where groundwater flow paths traverse Fe(II)-bearing sediments that can reduce Tc(VII) to relatively insoluble Tc(IV) phases.

The muscovite (001)-electrolyte interface is apparently simple, with a fixed lattice charge of the muscovite located below the surface and without under-coordinated surface oxygen sites that would lead to a strong pH dependent surface charge. Yet, we find that the adsorption structure of cations at this interfaces is unexpectedly complex. Previously, we found that Rb (super +) adsorbs in the ditrigonal site as an inner-sphere (IS) species, while Sr (super 2+) adsorbs as both IS and outer-sphere (OS) species [1]. A systematic study of a range of divalent cations has shown that there exists a third adsorbed species, an extended OS species (OS (sub ext) ), and the partitioning between these three species is controlled by the cation hydration enthalpy [2]. Ongoing work has extended these observations to other multivalent ions (Y (super 3+) , Th (super 4+) ) whose adsorption structure can be understood in the same context as that observed for divalent ions. We have also explored the role of competitive adsorption to influence the distribution of adsorbed cations. Specifically we have found that the partitioning of cations between IS, OS and OS (sub ext) species can change with the introduction of competing cations. Furthermore, the introduction of natural organic matter (in the form of dissolved fulvic acid) can dramatically alter the adsorbed cation distribution which is controlled by a balance between cation hydration, cation organophillicity, and cation-mineral interactions.

There is a need to develop a fundamental understanding of actinide-aggregate formation under conditions that promote hydrolysis. We are developing the scientific basis for a molecular-level understanding of nanoaggregate species in terms of their structures, stabilities, formation reactions, and surface reactivities, particularly the formation of colloidal particles containing heavy elements. In addition, this research will help us to meet the need to develop new separations strategies for next generation nuclear fuels that are better able to remove stable metal aggregates without the need for extreme solution conditions. Our focus is on the initial aqueous reactions including olation and oxolation as well as the acidity of metal ions in solution. For the +2 metal aquo ions, it is possible to predict the size of the first solvation shell by predicting the correct pK (sub a) in terms of experiment. Positive ions with a charge > +2 require more solvent shells in order to predict the pK (sub a) reliably. We have studied a wide range of oxolaton and olation reactions of +2 cations and the type of reaction that dominates in terms of the thermodynamics is dependent on the cation size, the size of the first solvation shell, and the electronic structure of the ion. The structures of (ThO (sub 2) ) (sub n) nanoclusters have been studied and compared to the analogous transition metal nanoclusters. Calculations of the hydrolysis reactions of the nanoclusters provide for the first time an estimate of the physisorption and dissociative chemisortion energies of H (sub 2) O on the ThO (sub 2) surface. The electronic structure of nanoparticles containing a Th (sub 6) O (sub 8) core will be discussed including predictions of particle acidity and proton location. These particles are of interest as they contain a Th (sub 6) O (sub 8) core embedded in an anion shell. There is good agreement between theory and experiment for the structures of the clusters.

The membrane electrode assemblies in the reference PEFC stack use nanostructured, thin-film ternary catalysts supported on organic whiskers and a modified perfluorosulfonic acid membrane. The analyses show that the stack Pt content can be reduced by 50% and the projected high-volume manufacturing cost by >45% for the stack and by 25% for the system, if the design-point system efficiency is lowered from 50% to 40%. The resulting penalties in performance are a <1% reduction in the system peak efficiency; a 2-4% decrease in the system efficiency on the urban, highway, and LA92 drive cycles; and a 6.3% decrease in the fuel economy of the modeled hybrid fuel-cell vehicle on the combined cycle used by EPA for emission and fuel economy certification. The stack heat load, however, increases by 50% at full power (80 kW sub(e)) but by only 23% at the continuous power (61.5 kW sub(e)) needed to propel the vehicle on a 6.5% grade at 55 mph. The reduced platinum and system cost advantages of further lowering the design-point efficiency from 40% to 35% are marginal. The analyses indicate that thermal management in the lower efficiency systems is very challenging and that the radiator becomes bulky if the stack temperature cannot be allowed to increase to 90-95 degree C under driving conditions where heat rejection is difficult.

Although both processes harvest the energy in sunlight, they operate in distinctly different ways and produce different types of products: biomass or chemical fuels in the case of natural photosynthesis and nonstored electrical current in the case of photovoltaics. In order to find common ground for evaluating energy-conversion efficiency, we compare natural photosynthesis with present technologies for photovoltaic-driven electrolysis of water to produce hydrogen. Photovoltaic-driven electrolysis is the more efficient process when measured on an annual basis, yet short-term yields for photosynthetic conversion under optimal conditions come within a factor of 2 or 3 of the photovoltaic benchmark. We consider opportunities in which the frontiers of synthetic biology might be used to enhance natural photosynthesis for improved solar energy conversion efficiency.

Biosyn registered , a bioabsorbable co-polymer of glycolide, dioxanone, and trimethylene carbonate, was successfully electrospun into tubular conduits for the first time for soft tissue applications. At an electric field strength of 1 kV cm-1 over a distance of 22 cm (between the Taylor cone and the collector) and at a flow rate of 1.5 ml h-1 different concentrations of Biosyn/HFP solutions (5-20%) were spun into nanofibers and collected on a rotating mandrel (diameter 4 mm) at 300 and 3125 r.p.m. Scaffolds were characterized for structural and morphological properties by differential scanning calorimetry and scanning electron microscopy and for mechanical properties by uniaxial tensile testing (in both the circumferential and longitudinal directions). Biosyn registered tubular scaffolds (internal diameter 4 mm) have been shown to exhibit a highly porous structure (60-70%) with a randomly oriented nanofibrous morphology. The polymer solution concentration directly affects spinnability and fiber diameter. At very low concentrations (a[copy1/25%) droplets were formed due to electrospraying. However, as the concentration increased the solution viscosity increased and a "bead-on-string" morphology was observed at 10%. A further increase in concentration to 13% resulted in "bead-free" nanofibers with diameters in the range 500-700 nm. Higher concentrations (a[copy3420%) resulted in the formation of microfibers (1-1.4 mu m diameter) due to increased solution viscosity. It has also been noted that increasing the mandrel speed from 300 to 3125 r.p.m. produced a reduction in the fiber size. Uniaxial tensile testing of the scaffolds revealed the mechanical properties to be attractive for soft tissue applications. As the fiber diameters of the scaffold decrease the tensile strength and modulus increase. There is no drastic change in tensile properties of the scaffolds tested under hydrated and dry conditions. However, a detailed study on the biodegradation and biomechanics of electrospun Biosyn conduits under physiological pressure conditions is required to ensure potential application as a vascular graft.

Long-term aluminum hydroxide precipitation tests in borated water AN - 889424028; 14977177 AB - Long-term aluminum (Al) hydroxide precipitation tests were conducted in slightly alkaline solutions containing 2500 ppm boron. The solution temperature was cycled to obtain a temperature history more representative of emergency core cooling system temperatures after a loss-of-coolant accident. The observed Al precipitation boundary was close to predicted results for amorphous precipitates, which are higher than the solubility expected for crystalline forms. Bench-scale and loop head loss test results under various conditions were successfully combined into single map in a temperature - 'pH + p[Al] sub(T') domain, which yielded two bounding lines for Al hydroxide solubility in borated alkaline water that depend on whether or not loop head loss tests with Al alloy coupons are included. Precipitates were observed to form either as fine, cloudy suspensions, which showed very little tendency to settle, or as flocculated precipitates. The flocculation tendency of the precipitates can be qualitatively explained by a colloid stability theory or a phase diagram for protein solutions.

This subcritical assembly was constructed to study the physics and the operation of accelerator-driven subcritical systems (ADS) for transmuting the light water reactors (LWR) spent nuclear fuel. The YALINA Booster facility has been accurately modeled, with no material homogenization, by the Monte Carlo codes MCNPX (MCNP/MCB) and MONK. The MONK geometrical model matches that of MCNPX. The assembly has also been analyzed by the deterministic code ERANOS. In addition, the differences between the effective neutron multiplication factor and the source multiplication factors have been examined by alternative calculational methodologies. The analyses include the delayed neutron fraction, prompt neutron lifetime, generation time, neutron flux profiles, and spectra in various experimental channels. The accuracy of the numerical models has been enhanced by accounting for all material impurities and the actual density of the polyethylene material used in the assembly (the latter value was obtained by dividing the total weight of the polyethylene by its volume in the numerical model). There is good agreement between the results from MONK, MCNPX, and ERANOS. The ERANOS results show small differences relative to the other results because of material homogenization and the energy and angle discretizations.The MCNPX results match the experimental measurements of the [super]3He(n,p) reaction rates obtained with the californium neutron source.

However, exposure to neutron irradiation for extended periods not only changes the microstructure and microchemistry of these steels, but also degrades their fracture properties. The existing data on irradiated austenitic SSs are reviewed to determine the effects of key parameters such as material type and condition and irradiation temperature, dose, and dose rate on neutron embrittlement. Differences in the radiation-induced degradation of fracture properties between LWR and fast-reactor irradiations are also discussed. The results are used to (a) define a threshold fluence above which irradiation effects on fracture toughness of the material are significant, (b) evaluate the potential of neutron embrittlement under LWR operating conditions, and (c) assess the potential effects of voids on fracture toughness.

It has been debated whether using corn ethanol results in any energy and greenhouse gas benefits. This issue has been especially critical in the past several years, when indirect effects, such as indirect land use changes, associated with U.S. corn ethanol production are considered in evaluation. In the past three years, modeling of direct and indirect land use changes related to the production of corn ethanol has advanced significantly. Meanwhile, technology improvements in key stages of the ethanol life cycle (such as corn farming and ethanol production) have been made. With updated simulation results of direct and indirect land use changes and observed technology improvements in the past several years, we conducted a life-cycle analysis of ethanol and show that at present and in the near future, using corn ethanol reduces greenhouse gas emission by more than 20%, relative to those of petroleum gasoline. On the other hand, second-generation ethanol could achieve much higher reductions in greenhouse gas emissions. In a broader sense, sound evaluation of U.S. biofuel policies should account for both unanticipated consequences and technology potentials. We maintain that the usefulness of such evaluations is to provide insight into how to prevent unanticipated consequences and how to promote efficient technologies with policy intervention.

Argonne National Laboratory (ANL) of USA and Kharkov Institute of Physics and Technology (KIPT) of Ukraine have been collaborating on the conceptual design development of an experimental neutron source facility consisting of an electron accelerator driven sub-critical assembly. The neutron source driving the sub-critical assembly is generated from the interaction of 100KW electron beam with a natural uranium target. The sub-critical assembly surrounding the target is fueled with low enriched WWR-M2 type hexagonal fuel assemblies. The U-235 enrichment of the fuel material is <20%. The facility will be utilized for basic and applied research, producing medical isotopes, and training young specialists. With the 100KW electron beam power, the total thermal power of the facility is a arrow right 4360kW including the fission power of a arrow right 4260kW. The burnup of the fissile materials and the buildup of fission products continuously reduce the system reactivity during the operation, decrease the neutron flux level, and consequently impact the facility performance. To preserve the neutron flux level during the operation, the fuel assemblies should be added and shuffled for compensating the lost reactivity caused by burnup. Beryllium reflector could also be utilized to increase the fuel life time in the sub-critical core.

These data were analyzed in a geographic information system environment together with relevant data sets (e.g., topography, geology, remote sensing) to assess the utility of GRACE for monitoring elements of hydrologic systems on local scales. The following were observed over the Niger, Congo, and Nile Basins: (1) large persistent anomalies (standard deviation, SD>10 cm) on SD images over periods of 2-7 yr; (2) anomalous areas originate at mountainous source areas that receive high precipitation, extend downslope toward mountain foothills, and often continue along main channels, wetlands, or lakes that drain these areas; (3) time-series analyses over anomalous areas showed that seasonal mass variation lags behind seasonal precipitation; and (4) seasonal mass variations showed progressive shift in phase and decrease in amplitude with distance from the mountainous source areas. Results indicate that (1) the observed temporal mass variations are largely controlled by elements of the hydrologic cycle (e.g., runoff, infiltration, groundwater flow) and have not been obscured by noise, as previously thought; and (2) it is possible to use GRACE to investigate the temporal local responses of a much larger suite of hydrologic systems (watersheds, lakes, rivers, and marshes) and domains (source areas and lowlands) within watersheds and subbasins worldwide.

Bioreduction experiments were conducted with combinations of chlorite, U(VI), and anthraquinone-2,6-disulfonate (AQDS). Abiotic experiments were conducted to quantify the reduction of U(VI) by chemically-reduced chlorite-associated Fe(II), the oxidation of nanoparticulate U(IV) by unaltered structural Fe(III) in chlorite, and the sorption of U(VI) to chlorite, to elucidate interactions between U(VI)/U(IV) and Fe(II)/Fe(III)-chlorite. Solids were characterized by X-ray diffraction, scanning electron microscopy, and X-ray absorption spectroscopy to confirm Fe and U reduction and reoxidation. U(VI) enhanced the reduction of structural Fe(III) in chlorite and nanoparticulate U(IV) was oxidized by structural Fe(III) in chlorite, demonstrating that U served as an effective electron shuttle from S. oneidensis MR-1 to chlorite-Fe(III). Abiotic reduction of U(VI) by chlorite-associated Fe(II) was very slow compared to biological U(VI) reduction. The rate of nanoparticulate U(IV) oxidation by dissolved oxygen increased in the presence of chlorite-associated Fe(II), but the extent of U(IV) oxidation decreased as compared to no-chlorite controls. In identical experiments conducted with bioreduced suspensions of nanoparticulate U(IV) and nontronite (another iron-bearing phyllosilicate), the rate of U(IV) oxidation by dissolved oxygen increased in the presence of nontronite-associated Fe(II). In summary, we found that structural Fe(III) in chlorite delayed the onset of U(VI) loss from solution, while chlorite-associated Fe(II) enhanced the oxidation rate of U(IV) by dissolved oxygen, indicating that chlorite-associated Fe(II) could not protect nanoparticulate U(IV) from oxygen intrusion but instead increased the oxidation rate of U(IV).

In this study we show that the formation of Au-anomalous calcrete can be biomediated through the activity of resident microorganisms, and may not simply be the result of passive nucleation on inactive cells or evapotransporative processes. Calcified microfossils are highly abundant in calcrete from the Barns Au-prospect in South Australia. These microfossils are morphological analogues of calcified cells and biofilms formed in laboratory experiments conducted with active bacterial cultures enriched from Au-anomalous calcareous sand from the Barns prospect. Calcium carbonates precipitated by these cultures consisted mostly of calcite, which is the main carbonate mineral in calcrete. Synchrotron micro-X-ray fluorescence (S-mu XRF) mapping was used to assess the distribution of Au, Zn, Ca and other metals in Ca carbonates precipitated by active bacterial cultures. On a mu m-scale the distribution of Au was heterogeneous in these Ca carbonates and differed from base metal distribution, thus mimicking the spatial separation of these metals observed in calcrete. The speciation of Au in Ca carbonates precipitated by active bacteria was measured using micro-X-ray absorption near edge structure spectroscopy (mu -XANES) and resembled that observed in Au-anomalous calcrete closely. While metallic Au was observed in Au 'hotpots', ionic Au was detected in the halo surrounding the 'hotspot'. In contrast, the precipitates produced in the presence of dead bacterial cells or by raising solution pH or pCO (sub 2) , i.e., hydroxylapatite, portlandite and vaterite, respectively, did not reflect the mineralogy of calcrete. Gold distribution and speciation in vaterite, formed by raising pCO (sub 2) , were homogenous and did not reproduce the variation observed in calcrete and Ca carbonates precipitated by active cells. Increasing the supersaturation with respect to Ca in solution by incremental drying of the medium produced only X-ray amorphous precipitates, or hydroxylapatite in the presence heat-killed cells. In conclusion, this study shows that active microbial processes that combine biogenic Ca carbonatogenesis with Au precipitation are likely to drive the formation of Au-anomalous calcrete.

Reconciling contradictory geochemical and geophysical observations at ocean ridges requires a better understanding of transport properties in partially molten rocks. Using X-ray synchrotron microtomography, we obtained three-dimensional data on melt distribution for mantle peridotite with various melt fractions. At melt fractions as low as 0.02, triple junctions along grain edges dominated the melt network; there was no evidence of an abrupt change in the fundamental character of melt extraction as melt fraction increased to 0.2. The porosity of the partially molten region beneath ocean ridges is therefore controlled by a balance between viscous compaction and melting rate, not by a change in melt topology.

The experiments use the extraordinary sensitivity provided by H-atom ARAS detection with an unreversed light source to measure both the total decomposition rate and the branching to radical products versus molecular products, with the molecular products arising predominantly through roaming according to the theoretical analysis. The experimental observations also provide a measure of the rate coefficient for H + CH sub(3OCH) sub(3). An evaluation of the available experimental results for H + CH sub(3OCH) sub(3) can be expressed by a three parameter Arrhenius expression as, [inline image] The potential energy surface is explored with high level ab initio electronic structure theory. The dynamics of roaming versus radical formation is studied with a reduced dimensional trajectory approach. The requisite potential energy surface is obtained from an interpolative moving least squares fit to wide-ranging ab initio data for the long-range interactions between methyl and methoxy. The predicted roaming and radical micro-canonical fluxes are incorporated in a master equation treatment of the temperature and pressure dependence of the dissociation process. The tight (i.e., non-roaming) transition states leading to a variety of additional molecular fragments are also included in the master equation analysis, but are predicted to have a negligible contribution to product formation. The final theoretical results reliably reproduce the measured dissociation rate to radical products reported here and are well reproduced over the 500-2000 K temperature range and the 0.01-300 bar pressure range by the following modified Arrhenius parameters for the Troe falloff format:[inline image]The experimentally observed branching ratio of 0.19 +/- 0.07 provides a direct measure of the contribution from the roaming radical mechanism.

TG data show a 25.6+ or -0.1% weight loss below 300 degrees C, ascribed to the removal of surface water since PDF analysis shows no change in the structure of ferrihydrite up to this temperature. The transformation to hematite occurs at around 415+ or -1 degrees C (peak temperature) at a heating rate of 10 degrees C/min, with no obvious weight change during or after the transformation. In situ PDF analysis indicates that the ferrihydrite bulk structure remained intact up to the direct transition to crystalline hematite, with no intermediate phases, crystalline or amorphous, formed. In situ IR data shows the extent of absorption attributable to OH stretching in ferrihydrite at 215 degrees C dropped to 10% of its room-temperature value. These results suggest ferrihydrite contains very little structural OH: the molar ratio of OH/Fe is 0.18+ or -0.01. A recently proposed akdalaite-like ferrihydrite model has an OH/Fe equal to 0.2, consistent with this result. The 3-phase model proposed by Drits et al. (1993) has an average formula close to FeOOH, with an OH/Fe equal to 1.0, far more than suggested by our experiments. Based on the constraints set by the estimated water content and the PDF signatures, we examined possible anion packing types and local structural motifs in ferrihydrite, and demonstrate that ABAC is the only feasible packing type and that a peak at 3.44(2) Aa in PDF provides indirect evidence for the presence of tetrahedral Fe.

This species is known as a key intermediate in Thermal DeNO sub(x), where NH sub(3) is used as a reducing agent for selective non-catalytic reduction of NO. In addition, NNH has been proposed to facilitate formation of NO from thermal fixation of molecular nitrogen through the so-called NNH mechanism. The importance of NNH for formation and reduction of NO depends on its thermal stability and its major consumption channels. In the present work, we study reactions on the NNH + O, NNH + O sub(2), and NH sub(2) + O sub(2) potential energy surfaces using methods previously developed by Miller, Klippenstein, Harding, and their co-workers. Their impact on Thermal DeNO sub(x) and the NNH mechanism for NO formation is investigated in detail.

Interaction layer (IL) growth between fuel particles and the matrix is one of performance issues. The interaction layer growth data for U sub(3)Si, U sub(3)Si sub(2) and USi dispersions in Al were obtained from both out-of-pile and in-pile tests. The IL is dominantly U(AlSi) sub(3) from out-of-pile tests, but its (Al + Si)/U ratio from in-pile tests is higher than the out-of-pile data, because of amorphous behavior of the ILs. IL growth correlations were developed for U sub(3)Si-Al and U sub(3)Si sub(2)-Al. The IL growth rates were dependent on the U/Si ratio of the fuel compounds. During irradiation, however, the IL growth rates did not decrease with the decreasing U/Si ratio by fission. It is reasoned that transition metal fission products in the IL compensate the loss of U atoms by providing chemical potential for Al diffusion and volume expansion by solid swelling and gas bubble swelling. The addition of Mo in U sub(3)Si sub(2) reduces the IL growth rate, which is similar to that of UMo alloy dispersion in a silicon-added Al matrix.

Modern engines employ micro-orifices with different orifice designs. It is critical to characterize the effects of various designs on engine performance and emissions. In this study, a recently developed primary breakup model (KH-ACT), which accounts for the effects of cavitation and turbulence generated inside the injector nozzle is incorporated into a CFD software CONVERGE for comprehensive engine simulations. The effects of orifice geometry on inner nozzle flow, spray, and combustion processes are examined by coupling the injector flow and spray simulations. Results indicate that conicity and hydrogrinding reduce cavitation and turbulence inside the nozzle orifice, which slows down primary breakup, increasing spray penetration, and reducing dispersion. Consequently, with conical and hydroground nozzles, the vaporization rate and fuel air mixing are reduced, and ignition occurs further downstream. The flame lift-off lengths are the highest and lowest for the hydroground and conical nozzles, respectively. This can be related to the rate of fuel injection, which is higher for the hydroground nozzle, leading to richer mixtures and lower flame base speeds. A modified flame index is employed to resolve the flame structure, which indicates a dual combustion mode. For the conical nozzle, the relative role of rich premixed combustion is enhanced and that of diffusion combustion reduced compared to the other two nozzles. In contrast, for the hydroground nozzle, the role of rich premixed combustion is reduced and that of non-premixed combustion is enhanced. Consequently, the amount of soot produced is the highest for the conical nozzle, while the amount of NO sub(x) produced is the highest for the hydroground nozzle, indicating the classical tradeoff between them.

However, exposure to neutron irradiation for extended periods changes the microstructure (radiation hardening) and microchemistry (radiation-induced segregation) of these steels, and degrades their fracture properties. Irradiation-assisted stress corrosion cracking (IASCC) is another degradation process that affects LWR internal components exposed to neutron radiation. The existing data on irradiated austenitic SSs were reviewed to evaluate the effects of key parameters such as material composition, irradiation dose, and water chemistry on IASCC susceptibility and crack growth rates of these materials in LWR environments. The significance of microstructural and microchemistry changes in the material on IASCC susceptibility is also discussed. The results are used to determine (a) the threshold fluence for IASCC and (b) the disposition curves for cyclic and IASCC growth rates for irradiated SSs in LWR environments.

In addition to the classic PTS system, a PTS-independent secondary system has been described in which nucleotide-dependent sugar kinases are used for monosaccharide phosphorylation. Fructokinase (FK), which phosphorylates d-fructose with ATP as a cofactor, has been shown to be a member of this secondary system. Bioinformatic analysis has shown that FK is a member of the "ROK" (bacterial Repressors, uncharacterized Open reading frames, and sugar Kinases) sequence family. In this study, we report the crystal structures of ROK FK from Bacillus subtilis (YdhR) (a) apo and in the presence of (b) ADP and (c) ADP/d-fructose. All structures show that YdhR is a homodimer with a monomer composed of two similar alpha / beta domains forming a large cleft between domains that bind ADP and d-fructose.

Successful modeling of battery designs relies upon accurate calculation of the area specific impedance (ASI). A simplified calculation of the ASI is presented that accounts for physical limitations without performing computationally expensive calculations. The limiting currents for transport within the electrolyte and within the intercalation materials are implemented into a linear form of the Butler-Volmer equation to calculate the interfacial impedance. Lithium-ion batteries are then designed to examine the effect of power to energy ratio on battery dimensions. A large ASI is shown to be detrimental to battery design regardless if the increase in impedance results from mass transport limitations or a reduction in electrochemical active area due to small electrode loadings. The smaller electrochemical active area does not increase the voltage losses of a battery when a constant C-rate is maintained. However, the higher ASI values from low electrode loadings require a larger separator and current collector area resulting in a greater battery volume and weight to achieve similar energy and power requirements when compared to a system with a lower ASI.

Comparing to the electrolyte used in the conventional lithium-ion batteries, which are flammable, volatile, and highly reactive organic carbonate solvents, silicon-based electrolytes are thermally and chemically stable, less flammable and environmental benign. Tri(ethylene glycol)-substituted trimethylsilane (1NM3) was identified as a focus of investigation due to its high conductivity and low viscosity. We present the results of a systematic investigation of the 1NM3-based electrolytes with lithium bis(oxalate)borate (LiBOB) salt, including temperature dependent ionic conductivity and lithium cell performance. Lithium-ion cell with LiNi sub(1/3)Co sub(1/3)Mn sub(1/3)O sub(2) as the positive electrode and MAG graphite as the negative electrode has shown excellent cyclability using 1NM3-LiBOB as electrolyte.

The populations of highway vehicles and two-wheelers are projected under three different scenarios on the basis of economic growth and average household size in India. The results show that by 2040, the number of highway vehicles in India would be 206-309 million. The oil demand projections for the Indian transportation sector are based on a set of nine scenarios arising out of three vehicle-growth and three fuel-economy scenarios. The combined effects of vehicle-growth and fuel-economy scenarios, together with the change in annual vehicle usage, result in a projected demand in 2040 by the transportation sector in India of 404-719 million metric tons (8.5-15.1 million barrels per day). The corresponding annual CO2 emissions are projected to be 1.2-2.2 billion metric tons.

This work investigates the impact of the electrode thickness on the energy density of (Li-ion) batteries. The impedance results from the hybrid pulse power characterization (HPPC) test indicate that the electrode resistance is inversely proportional to the electrode thickness. This feature makes it possible to use thicker electrodes in (Li-ion) batteries to meet PHEV power requirements. The practical electrode thickness is determined to be around 100 km, if considering the electrode mechanical integrity when using conventional PVDF binders. Furthermore, cycle performance shows that cells with a higher loading density have a similar capacity retention to cells with a lower loading density.

Both compounds exhibit a reversible redox wave over 4 V vs Li/Li super(+) with better solubility in a commercial electrolyte (1.2 M LiPF sub(6) dissolved in ethylene carbonate/ethyl methyl carbonate (EC/EMC 3/7) than the di-tert-butyl-substituted 1,4-dimethoxybenzene (DDB). The electrochemical stability of DBBD1 and DBBD2 was tested under charge/discharge cycles with 100% overcharge at each cycle in MCMB/LiFePO sub(4) and Li sub(4)Ti sub(5)O sub(12)/LiFePO sub(4) cells. DBBD2 shows significantly better performance than DBBD1 for both cell chemistries. The structural difference and reaction energies for decomposition have been studied by density functional calculations.

The collaboration rules that typically govern large science experiments as well as social networks of scientists span across the institutional security boundaries. A common concern is that the increased openness may allow malicious attackers to spread more readily around the grid. We consider how to optimally respond to attacks in open grid environments. To show how and why attacks spread more readily around the grid, we first discuss how collaborations manifest themselves in the grids and form the collaboration network graph, and how this collaboration network graph affects the security threat levels of grid participants. We present two mixed-integer program (MIP) models to find the optimal response to attacks in open grid environments, and also Calculate the threat level associated with each grid participant, Given an attack scenario, our optimal response model aims to minimize the threat levels at unaffected participants while maximizing the uninterrupted scientific production (continuing collaborations).

Constituent-material production and the subsequent manufacturing of batteries are emphasized. Of particular interest is estimation of the impact of battery material recycling on battery manufacturing. Because some materials come from comparatively less plentiful resources, the recycling of lithium ion batteries and the potential impact on battery-production life-cycle burdens are discussed. This effort represents the early stage of lithium ion battery life-cycle analysis, in which processes are characterized preparatory to detailed data acquisition. Notwithstanding the lack of data on production of battery materials, it is estimated that the energy use and greenhouse gas emissions associated with battery manufacturing make up only a small percentage of a plug-in hybrid vehicle's total life-cycle energy use. Further, the recycling of battery materials potentially can significantly reduce the material production energy.

Here, a stochastic approach is considered for explicitly including uncertainty in safety parameters by applying Monte Carlo sampling coupled with established deterministic reactor safety analysis tools. The Monte Carlo approach yields frequency distributions for reactor safety metrics (e.g., peak temperatures) that can be compared to performance limits, allowing for an improved determination of the safety margin and a clear determination of which safety parameters are most important to the transient response. Because the approach enables the estimation of probabilities for violating safety boundaries, it should be useful in a risk-based regulatory environment. It has the advantage of not requiring any substantial rewriting of existing safety analysis computer codes.

An electron accelerator drives a sub-critical facility (ADS) is used for generating the neutron source. The facility will be utilized for performing basic and applied nuclear researches, producing medical isotopes, and training young nuclear specialists. Monte Carlo code MCNPX has been utilized as the major design tool for the design, due to its capability to transport electrons, photons, and neutrons at high energies. However the ADS shielding calculations with MCNPX need enormous computational resources and the small neutron yield per electron makes sampling difficulty for the Monte Carlo calculations. The high energy electrons (E > 100 MeV) generate very high energy neutrons and these neutrons dominant the total radiation dose outside the shield. The radiation dose caused by high energy neutrons is [inline image]3-4 orders of magnitude higher than that of the photons. However, the high energy neutron fraction within the total generated neutrons is very small, which increases the sampling difficulty and the required computational time. To solve these difficulties, the user subroutines of MCNPX are utilized to generate a neutron source file, which record the generated neutrons from the photonuclear reactions caused by electrons. This neutron source file is utilized many times in the following MCNPX calculations for weight windows (importance function) generation and radiation dose calculations. In addition, the neutron source file can be sampled multiple times to improve the statistics of the calculated results. In this way the expensive electron transport calculations can be performed once with good statistics for the different ADS shielding problems. This paper presents the method of generating and utilizing the neutron source file by MCNPX for the ADS shielding calculation and similar accelerator facilities, and the accurate radiation dose analyses outside the shield using modest computational resources.

However, little experimental or computational work has been performed on the dynamics of fuel injectors. Recent studies have shown that it is possible to measure the three-dimensional geometry of the injector nozzle, and to track changes in that geometry as the needle opens and closes in real time. This has enabled the dynamics of the injector to be compared with the dynamics of the spray, and allows computational fluid dynamics (CFD) simulations to use realistic time-dependent flow passage geometries. In this study, X-ray phase-enhanced imaging has been used to perform time-resolved imaging of the needle seat area in several common-rail diesel injection nozzles. The fuel distributions of the sprays emitted by these injectors were also studied with fast X-ray radiography. Correlations between eccentric motions of the injector needle valve and oscillations in the fuel density as it emerges from the nozzle are examined.

ER - TY - JOUR T1 - A note on the seismic response of rigid cantilever retaining walls AN - 1671334197; 14602414 AB - The elasticity based dynamic response of retaining walls, attached to a semi-infinite elastic backfill stratum, has yet to be solved exactly. There are three analytical approximation approaches in the literature to simplify the equations of motion. The solutions based on these approaches can be numerically implemented. However, the frequency range for which these solutions may provide accurate results has not yet been established. In this paper, the exact frequency equation and frequency spectra for the problem under free vibration are presented first, and the three simplified equations of motion are then reviewed. Next, the exact frequency spectra are then used to assess the frequency range of applicability of the three approximation approaches. It is concluded that for all practical values of Poisson's ratio, all three approaches provide a reasonable approximation to the exact solution in the low frequency range of the first mode. The first mode response of the horizontal and rocking impedance functions, for the rigid retaining wall are then derived, based on the simplified equations of motion, and the numerical data are presented for the low frequency range identified.

We focus on a 28-year time period of satellite era from 1980 to 2007, during which a suite of aerosol data from satellite observations, ground-based measurements, and intensive field experiments have become available. We analyze the long-term global and regional aerosol trends and their relationship to the changes of aerosol and precursor emissions and assess the role aerosols play in the multi-decadal change of solar radiation reaching the surface (known as "dimming" or "brightening") at different regions of the world, including the major anthropogenic source regions (North America, Europe, Asia) that have been experiencing considerable changes of emissions, dust and biomass burning regions that have large interannual variabilities, downwind regions that are directly affected by the changes in the source area, and remote regions that are considered to representing "background" conditions.

Our recent work has explored the molecular-scale structural transformations of hematite surfaces that result from this process. Under both acidic (pH 3) and neutral (pH 7) conditions Fe(II) induces layer-by-layer dissolution or growth of the hematite (110) and (012) surfaces. In contrast, the hematite (001) surface develops a <1 nm-thick discontinuous film that displays structural relaxations different from the underlying surface. This demonstrates that Fe(II) activates localized growth and dissolution independent of macroscopic Fe(II) adsorption. We have further explored the effect of this process on the fate of the structurally-compatible trace element Ni. For both hematite and goethite we observe that aqueous Fe(II) induces the incorporation of adsorbed Ni into the iron oxide structure. In addition, pre-incorporated Ni is released into solution by Fe(II). The rates of release and incorporation are orders of magnitude slower than the rate of macroscopic Fe(II) adsorption but comparable to iron isotope equilibration. We propose that Fe(II) catalyzes a thermodynamically-controlled redistribution of Ni among the mineral bulk, mineral surface, and aqueous solution. This work has implications for the validity of proxies for ocean composition on the early Earth and micronutrient and contaminant availability in soil, sedimentary, and aquatic systems.

With this demonstration, ATTA has reached a new milestone of detecting isotopes at the abundance level of less than one part per quadrillion. Along with the previously demonstrated analyses of (super 81) Kr (229, 000 yr, approximately 10 (super -12) ) and (super 85) Kr (10.8 yr, approximately 10 (super -11) ), ATTA can now analyze all three long-lived noble gas radioisotopes covering a wide range of ages and applications in the earth sciences. The detection of (super 39) Ar was made possible by a large improvement (X100) in both the counting rate and counting efficiency of the ATTA method. We have developed a new apparatus (ATTA-3) to perform (super 81) Kr dating with a required sample size of 10-100 liters of water or ice.

To address this need, we determined potential impacts for 12 actual systems serving populations ranging from similar to 10 super(4) to over 10 super(6) persons by simulating contamination events for the systems. We found several consistent patterns in the estimated impacts (defined as the size of the population receiving an ingestion dose above a given level). Significant impacts, those similar to worst-case impacts, result from injections of contaminants at only a minority of nodes. For contaminants with high thresholds for adverse effects, significant exposures are concentrated near the injection location, and impacts are not sensitive to population served. However, for contaminants with low thresholds, significant exposures are present over a significant fraction of the system, and impacts are sensitive to population. When exposures are concentrated near the injection node, the area affected tends to decrease with increasing population density. Accounting for all possible exposures and events may complicate the design of contamination warning systems.

Natural magnetites present in sediments are typically highly impure with titanium, and structural Fe (III) replacement by Ti (IV) yields a proportional increase in the relative Fe (II) content in the metal sublattice to maintain bulk charge neutrality. Titanomagnetite (Fe (sub 3-x) Ti (sub x) O (sub 4) ) nanoparticles provide a high surface area pristine material for batch studies to evaluate the availability and reactivity of Fe (II) at the mineral surface. Fe (sub 3-x) Ti (sub x) O (sub 4) nanoparticles accept structural Ti (IV) into the octahedral metal sublattice up to x = 0.4; higher values up to x = 0.6 yield discrete amorphous Fe (II)/Ti (IV) phases on particle exteriors. In aqueous suspension, there is a net driving force for the movement of Fe (II) from the bulk Fe (sub 3-x) Ti (sub x) O (sub 4) structure to the nanoparticle surface with subsequent release of Fe (II) into solution to reach an equilibrium distribution between interior structural Fe (II)/Fe (III), near-surface Fe (II)/Fe (III), and aqueous Fe (II). Consumption of structural Fe (II) through both dissolution and redox reactions results in the replacement of octahedral cations with vacancies to form an Fe (II)-deficient titanomaghemitized surface. Spontaneous Fe (II) release from the solid into solution increases in extent systematically with both Ti-content and decreasing pH. The presence of Tc (VII) in solution, as an electron accepting probe molecule, also increases this driving force as Fe (II) at the surface reacts with the Tc (VII) to form of a mixed Fe (III)-Tc (IV) co-precipitate. In principle, this titanomaghemitization process is reversible and, under reducing conditions, structural reducing equivalents can be restored by an external Fe (II) source. Pre-oxidized Fe (sub 3-x) Ti (sub x) O (sub 4) nanoparticles were found to be systematically restorable to Tc (VII) reduction rate behavior of pristine titanomagnetites by exposure to various concentrations of aqueous Fe (II). The findings demonstrate that the reactive structural Fe (II) pool can be resupplied in these Fe (sub 3-x) Ti (sub x) O (sub 4) phases and suggest that the mechanism involves facile coupled electron/ion transport across the mineral-water interface.

Their particles' formation and transport can alter the porosity and permeability of geo-media. Therefore, more accurate quantitative and qualitative information about mineral nucleation and growth is required. In this work, we used a time-resolved simultaneous small angle x-ray scattering (SAXS)/grazing incidence (GISAXS) setup for real-time monitoring of water-mineral interfacial reactions. To observe the size, shape, distribution, and phase of hydrous iron oxide and calcium carbonate nanoparticles on quartz and mica surfaces as well as in solutions, we also used complementary techniques, such as atomic force microscopy, high resolution transmission electron microscopy, high resolution X-ray diffraction, and grazing incidence wide angle x-ray scattering. The solutions included different ionic strengths of sodium nitrate, arsenate, aluminum, and polyaspartate. The mineral nucleation and growth modes were monitored as a function of exposure time. We delineated the quantitative contributions between homogenous and heterogeneous mechanisms at varied environmental conditions. Hydrous iron oxide nanoparticles formed preferentially along steps rather than terraces, while amorphous calcium carbonate did not show any clear preference. Under aqueous conditions, newly formed nanoparticles did not exhibit any facets. The presence of arsenate and aluminum ions significantly influenced the sizes and crystallinities of hydrous iron oxide nanoparticles and altered their nucleation and growth kinetics. This study provides more accurate depiction of nucleation and growth of environmentally important minerals in solution as well as at active interfaces. Our findings have implications not only for hydrous oxide- or carbonate-containing biogeochemical systems, but also for environmental remediation (heavy metal removal and nuclear waste deposition site remediation) and geoengineering applications (geologic CO (sub 2) sequestration).

We examined the ability of three dissimilatory metal-reducing bacteria (Anaeromyxobacter dehalogenans strain K, Geobacter sulfurreducens PCA, and Shewanella putrefaciens CN32) to reduce U (VI) in three forms: hydrogen uranyl phosphate (HUP) nanoparticles on the cell wall of Bacillus subtilis bacteria precipitated by passive cell wall biomineralization; abiotically precipitated HUP; and aqueous uranyl ion. The reduction experiments were conducted at pH=6.8 with presence and absence of bicarbonate and phosphate. X-ray Absorption Fine Structure spectroscopy (XANES and EXAFS) showed varied reduction extent of U (VI) by the three bacteria. The biogenic HUP mineral was consistently more easily reduced than the abiotic HUP under the same experimental conditions. Higher extent of reduction was observed in the presence of bicarbonate. Reduction experiments under conditions that inhibited the HUP dissolution (i.e. high phosphate concentrations) showed smaller extents of U (VI) reduction. These results indicate reduction of the dissolved U (VI) species in the system, as opposed to direct electron transfer to the HUP mineral. EXAFS analysis shows that the reduced U (IV) species are consistent with mono-and bi-dentate phosphate complexation of the U (IV) atoms, as found in the U (super IV) Ca (PO (sub 4) ) (sub 2) mineral ningyoite.

The shape of the phonon DOS remained similar at all compression points, while the maximum (cutoff) energy increased regularly with decreasing volume. As a result, we present a generalized scaling law to describe the volume dependence of epsilon -Fe's total phonon DOS which, in turn, is directly related to the ambient temperature vibrational Gruneisen parameter (gamma (sub vib) ). Fitting our individual gamma (sub vib) data points with gamma (sub vib) = gamma (sub vib,0) (V/V (sub 0) ) (super q) , a common parameterization, we found an ambient pressure gamma (sub vib,0) = 2.0 + or - 0.1 for the range q = 0.8 to 1.2. We also determined the Debye sound velocity (v (sub D) ) from the low-energy region of the phonon DOS and our in situ measured volumes, and used the volume dependence of v (sub D) to determine the commonly discussed Debye Gruneisen parameter (gamma (sub D) ). Comparing our gamma (sub vib) (V) and gamma (sub D) (V), we found gamma (sub vib) to be approximately 10% larger than gamma (sub D) at any given volume. Finally, applying our gamma (sub vib) (V) to a Mie-Gruneisen type relationship and an approximate form of the empirical Lindemann melting criterion, we predict the vibrational thermal pressure and estimate the high-pressure melting behavior of epsilon -Fe at Earth's core pressures.

This study investigates the effects of 9, 10-anthraquinone-2, 6-disulfonate (AQDS), a synthetic electron shuttle often used as a surrogate for quinone moieties in humic substances, on transformations of Fe, S, and U under reducing conditions. Experiments were conducted in defined mineral medium containing 30 mM Fe (III), 5 mM sulfate, and 10 mM acetate, with and without 100 mu M AQDS and inoculated with sediment from the Rifle, CO, USA, Integrated Field Research Challenge (IFRC) Site. After the system reached steady state with respect to Fe (III) and sulfate reduction, aliquots of suspension were collected from each system and one set was pasteurized at 70 degrees C for 1 hr. The suspensions were then spiked with 500 mM U (VI). After 48 h, 100% of the added U was removed from solution in the non-pasteurized AQDS system. However, only 58%, 25%, and 11% of added U was removed in the no AQDS non-pasteurized, AQDS pasteurized, and no AQDS pasteurized systems, respectively. U XANES analysis of the hydrated solids indicated that, with the exception of the pasteurized system without AQDS, the majority (85-95%) of the U associated with the solids was reduced to U (IV). The results of the EXAFS analysis of U (IV) in the systems with and without AQDS (not pasteurized) are consistent with the formation of nanoparticulate uraninite. The results of this study suggest that microbial reduction was the dominant process contributing to the reduction of U (VI) over the timescale of this experiment and that the presence of AQDS enhanced both biotic and abtiotic/microbially mediated U (VI) reduction.

Added electron acceptors included 2-line ferrihydrite, goethite, or lepidocrocite, in the presence or absence of sulfate. The batch systems were inoculated with the native microbial community present in a subsurface sediment. The rate of Fe (super III) reduction was low in the absence of sulfate. However, the rate and extent of Fe (super III) reduction increased more than 10 times with 10 mM sulfate. Sulfate reduction occurred concurrently with Fe (super III) reduction suggesting abiotic Fe (super III) reduction by sulfide. X-ray absorption fine-structure (XAFS) analysis confirmed the formation of ferrous sulfide as the major secondary mineral phase in these incubations. The rates of sulfate and Fe (super III) reduction were significantly faster with lactate than with acetate. Lactate promoted both sulfate and Fe (super III) reduction in all incubations, while acetate stimulated sulfate and Fe (super III) reduction only in ferrihydrite and goethite incubations. Acetate oxidation was coupled with sulfate and Fe (super III) reduction; however, lactate was rapidly fermented to acetate and propionate, followed by propionate oxidation coupled with sulfate reduction. Terminal Restriction Fragment Length Polymorphism (T-RFLP) yielded unique microbial community profiles. The presence of sulfate resulted in distinct community development likely due to the proliferation of acetate- or propionate-utilizing, sulfate-reducing bacteria. During the experiment, the community in lepidocrocite incubations evolved in a very different way compared to those in the other Fe (super III) (hydr)oxide incubations indicating that the nature of the Fe (super III) (hydr)oxide can affect microbial community development. However, after the complete consumption of sulfate the microbial community compositions in all incubations (except lepidocrocite plus acetate incubation) were similar to each other. These results show that the availability of sulfate, the type of Fe (super III) (hydr)oxide present, and the added electron donor can have a strong effect on the development of subsurface microbial communities.

Since landfill gas (LFG) is a renewable resource, this energy is considered renewable. When used as a vehicle fuel, LFG-based compressed natural gas (CNG) consumes up to 1,100 Btu of fossil fuel and generates up to 120 g of carbon dioxide equivalent (gCO(2)e) greenhouse gas emissions per mile on a well-to-wheel basis. This amount compares with about 7,500 Btu and 500 gCO(2)e per mile for CNG from fossil natural gas and 8,000 Btu and 650 gCO(2)e per mile for petroleum gasoline. Liquefying the LFG consumes another 400+ Btu of fossil fuel and 30+ gCO(2)e per mile if grid electricity is used for the process. However, if some of the LFG is used to generate electricity for gas cleanup and liquefaction (or compression), liquefied natural gas (or CNG) produced from LFG can have no fossil fuel input and only minimal CO(2)e emissions on a well-to-wheel basis. This renewable natural gas is among the lowest carbon fuels in compressed or liquid form.

Precise knowledge of the mineral composition of the host phases is required for ultimate disposal. As determined by several analytical techniques, stable pollucite and celsian phases formed after sintering of bentonite and a simulated waste at 1200 degree C. This relatively low temperature was likely a result of several impurities in the bentonite and simulated waste stream. While most of the waste metal ions were enriched in the crystalline phases, trace amounts remained in a silica-rich glassy region with other impurities.

Pu uptake to the muscovite (001) surface from Pu (super 3+) solutions in a 0.1M NaClO (sub 4) background electrolyte at pH 3 follows an approximate Langmuir isotherm with an apparent adsorption constant, K (sub app) =5X10 (super 4) M (super -1) , and with a maximum coverage that is consistent with the amount needed to fully compensate the surface charge by trivalent Pu. The XR results show that the muscovite surface reacted with a 10 (super -3) M Pu (super 3+) solution (at pH 3 with 0.1M NaClO (sub 4) ) and dried in the ambient environment, maintains a 30-40 Aa thick layer, indicating the presence of a residual hydration layer (possibly including adventitious carbon). The RAXR results indicate that Pu sorbs on the muscovite surface with an intrinsically broad distribution with an average height of 18 Aa, substantially larger than heights expected for any specifically adsorbed inner- or outer-sphere complexes. These results are discussed in the context of recent studies of cation adsorption trends on muscovite and the possible roles of Pu hydrolysis species in controlling the Pu-muscovite interactions.

Nitrate (NO sub(3) super(-)) uptake rates inferred using the nutrient spiraling model underestimated the total NO sub(3) super(-) mass loss by 82%, which was attributed to the exclusion of dispersion and transient storage. The transient storage model was more accurate with respect to the NO sub(3) super(-) mass loss ( plus or minus 20%) and also demonstrated that uptake in the main channel was more significant than in storage zones. Conservative tracer fitting was unable to produce transport parameter estimates for a riffle-pool transition of the study reach, while forward modeling of solute transport using measured/scaled transport parameters matched conservative tracer breakthrough curves for all reaches. Additionally, solute exchange between the main channel and embayment surface storage zones was quantified using first-order theory. These results demonstrate that it is vital to account for transient storage in quantifying nutrient uptake, and the continued development of measurement/scaling techniques is needed for reactive transport modeling of streams with complex hydraulic and geomorphic conditions.

During recrystallization the grain size is transformed from micron to sub-micron sizes. The intergranular bubble-size distribution post-recrystallization is found to evolve with similar kinetics and morphology to that pre-recrystallization with any differences primarily due to gas content and initial and/or boundary conditions (e.g., fuel microstructure). The predictions of the theory are compared with measured bubble-size distributions in pre and post recrystallized U-10Mo alloy fuel.

These processes control the fuel air mixing, which in turn is critical for the combustion process. The differences in the physical properties of petrodiesel and biodiesel are expected to significantly alter the inner nozzle flow and spray structure and, thus, the performance and emission characteristics of the engine. In this study, the inner nozzle flow dynamics of these fuels are characterized by using the mixture-based cavitation model in FLUENT v6.3. Because of its lower vapor pressure, biodiesel was observed to cavitate less than petrodiesel. Higher viscosity of biodiesel resulted in loss of flow efficiency and reduction in injection velocity. Turbulence levels at the nozzle orifice exit were also lower for biodiesel. Using the recently developed KH-ACT model, which incorporates the effects of cavitation and turbulence in addition to aerodynamic breakup, the inner nozzle flow simulations are coupled with the spray simulations in a "quasi-dynamic" fashion. Thus, the influence of inner nozzle flow differences on spray development of these fuels could be captured, in addition to the effects of their physical properties. Spray penetration was marginally higher for biodiesel, while cone angle was lower, which was attributed to its poor atomization characteristics. The computed liquid lengths of petrodiesel and biodiesel were compared with data from Sandia National Laboratories. Liquid lengths were higher for biodiesel due to its higher boiling temperature and heat of vaporization. Though the simulations captured this trend well, the liquid lengths were underpredicted, which was attributed to uncertainty about the properties of biodiesel used in the experiments. Parametric studies were performed to determine a single parameter that could be used to account for the observed differences in the fuel injection and spray behavior of petrodiesel and biodiesel; fuel temperature seems to be the best parameter to tune.

AN - 764545062; 20704288 AB - A density functional theory study of the decomposition of methanol on Cu(4) and Co(4) clusters is presented. The reaction intermediates and activation barriers have been determined for reaction steps to form H(2) and CO. For both clusters, methanol decomposition initiated by C-H and O-H bond breaking was investigated. In the case of a Cu(4) cluster, methanol dehydrogenation through hydroxymethyl (CH(2)OH), hydroxymethylene (CHOH), formyl (CHO), and carbon monoxide (CO) is found to be slightly more favorable. For a Co(4) cluster, the dehydrogenation pathway through methoxy (CH(3)O) and formaldehyde (CH(2)O) is slightly more favorable. Each of these pathways results in formation of CO and H(2). The Co cluster pathway is very favorable thermodynamically and kinetically for dehydrogenation. However, since CO binds strongly, it is likely to poison methanol decomposition to H(2) and CO at low temperatures. In contrast, for the Cu cluster, CO poisoning is not likely to be a problem since it does not bind strongly, but the dehydrogenation steps are not energetically favorable. Pathways involving C-O bond cleavage are even less energetically favorable. The results are compared to our previous study of methanol decomposition on Pd(4) and Pd(8) clusters. Finally, all reaction energy changes and transition state energies, including those for the Pd clusters, are related in a linear, Brønsted-Evans-Polanyi plot. JF - The journal of physical chemistry.

To ensure energy security, significant efforts have been made to explore renewable energy sources and broaden the energy portfolio. However, the uncertainty and regional impacts associated with a new mix of energy resources for various regions under climate forcings are not well understood and fully explored in a systematic manner. We examine the water resource region of Upper Mississippi River Basin (UMRB), which plays a central role of biofuel production in United States, by using a soil and water assessment tool. The study is to evaluate potential impacts on water flows, nutrient cycles, and environmental integrity under projected biofuel growth, change in land use, and global climate change. The key elements of the water flow components (such as surface runoff, soil water storage, groundwater recharge, etc.) and soil properties that alter balance of water flows are investigated to identify their responses to potential biofuel production and climate change. The resultant changes in nutrient loading in river water are predicted accordingly. Some of dynamic interrelationships among water, biofuel production, and climate change are quantified and demonstrated to address future sustainability.

The timing of road salt application relative to thaw events and spring rains is critical to understanding the potential effect of salt on aquatic ecology. Also important is determining whether the watershed flushes the chloride or accumulates it from year to year. In this study, a wetland system in northeast Illinois was monitored for five years by collecting continuous (hourly) specific conductivity readings at key stations, supplemented by occasional hand measurements at many additional locations. The wetlands receive runoff from parking lots, road, forested areas, and a highway cloverleaf. In addition to the conductivity measurements, water samples were collected at various times and locations corresponding to a wide range of conductivity measurements and analyzed for chloride content. These were strongly correlated to the conductivity values (R (super 2) =0.99) and allowed the numerous conductivity readings to be used to represent chloride concentration with confidence. The study demonstrated the value of numerous, quick, and inexpensive continuous and manual water conductivity measurements for assessing the road salt load of waters within and entering the wetland basin. The data demonstrated that the chloride concentrations at individual measurement stations fluctuate wildly throughout the year, with large increases during the salting season, and sudden, but brief, decreases resulting from winter, spring, or summer rain. The data also show that winter salting has a prolonged effect on the chloride concentrations in the wetland, as chloride concentrations had an overall downward trend during the spring growth season and summer, yet remained above background levels until July. Such observations are significant in evaluating the effects of the salt on the wetland ecology, but they would not have been possible with a traditional water sampling program.

We adopted methodologies that heavily rely on readily available remote sensing datasets for the assessment, management, and hydrologic modeling of the water resources of such remote and inadequately gauged regions. The Soil and Water Assessment Tool was selected for continuous (1998-2005) rainfall-runoff modeling of the NE part of the Pishin Lora Basin (NEPL), a politically unstable area that is lacking adequate rain gauge and stream flow data. To account for the paucity of rain gauge and stream flow gauge data, inputs to the model included satellite-based TRMM precipitation data and modeled runoff was calibrated against satellite-based observations. These include: (1) monthly estimates of the water volumes impounded by the Khushdil Khan and the Kara Lora Reservoirs, and (2) inferred wet versus dry conditions in streams across the NEPL throughout the examined period. Calibrations were also conducted against observed flow reported from the Burj Aziz Khan station at the NEPL outlet. Model simulations indicate: (1) average annual precipitation (1998-2005), surface runoff, and net recharge are 1,300 X 10 (super 6) m (super 3) , 148 X 10 (super 6) m (super 3) , and 361 X 10 (super 6) m (super 3) , respectively; (2) within the NEPL watershed, precipitation and runoff are high for the NE (precipitation: 194 mm/y; runoff: 38 X 10 (super 6) m (super 3) /y) and NW (134 mm/y; 26 X 10 (super 6) m (super 3) /y) basins compared to the southern basin (124 mm/y; 8 X 10 (super 6) m (super 3) /y); and (3) construction of delay action dams in the NE and NW basins of the NEPL could increase recharge from 361 X 10 (super 6) m (super 3) /y up to 432 X 10 (super 6) m (super 3) /y and achieve sustainable extraction. The adopted methodologies should not be considered as a substitute for traditional field-based approach, provide first order estimates for rainfall, runoff, and recharge in the arid and semi-arid parts of the world that are inaccessible and/or lack adequate coverage with stream flow and precipitation data.

Geostatistical methods provide a means for exploring that correlation structure, allowing comparisons of results from different geomorphological settings and approaches. In this study, indicator geostatistics and transition probability geostatistics are applied to nearly 300 km of drilling data derived from over 11,000 private well drilling logs and over 200 high-quality well logs from monitoring well installation. Analyses are focused on a 12,000-km (super 2) region in central Minnesota in a setting dominated by the late-Wisconsinan Rainy, Superior, and Wadena lobes. The drilling data are categorized according to the logged sediment descriptions. In one scheme, the materials are separated according to presumed high or low hydraulic conductivity (K) for use in binary indicator geostatistical and transition probability geostatistical analyses. In another, the number of categories is expanded to five on the basis of combined K and depositional setting information for use in a separate transition probability analysis. The data are separated into different geomorphological settings associated with various depositional environments of several ice advances. Vertical variograms are very well supported in all geomorphological areas, while lateral variograms vary from well supported to random scatter. The ratio of vertical to lateral range varies but has an average value of ten. Results for the numerous geomorphological settings indicate overlapping geostatistical ranges, sills, and vertical lens thicknesses. A lack of stationarity was observed, consistent with a fundamental complexity of glacial depositional and erosional processes. Correlation generally varied as much between geographically distinct zones of like geomorphology as it did between zones of different geomorphology. High-resolution data associated with monitoring well installation typically deviated from the private well data; this is attributed to site-specific geology and detailed logging of thin units. Overall results underscore the difficulty in correlative assumptions in glaciated regions.

Despite its importance in biogeochemistry, many questions remain about the mechanism of this electron transfer reaction, in part because the speed of the fundamental chemical steps renders them inaccessible to conventional study. Time-resolved X-ray spectroscopy is a technique that can overcome this limitation and measure changes in oxidation state and structure occurring on the ultrafast timescale. We use this approach, in conjunction with femtosecond optical spectroscopy, to measure electron transfer rates and the speciation of Fe atoms in iron oxide nanoparticles following laser excitation of a surface-bound dye molecule. Both maghemite and ferrihydrite nanoparticles were synthesized by co-precipitation of Fe (super 3+) in basic solution with a varying amount of Fe (super 2+) , giving particles 1.5-3 nm in diameter. UV/vis absorption and fluorescence spectroscopy showed that the dye, 2,7-dichlorofluorescein, binds strongly to the particle surface and that its emission is quenched fully when bound. Under steady-state photoexcitation, dye-sensitized particles evolve Fe (super 2+) (aq) over time, indicating electron transfer from sensitizer to particle followed by reductive dissolution. Pump-probe X-ray absorption spectroscopy measurements at the Fe K edge show the transient formation of reduced iron species within approximately 100 ps following laser excitation of the dye molecule, which is not seen. Ultrafast optical spectroscopy of the sensitizer molecule shows electron injection occurs within the X-ray pulse length. No transient species were observed in control experiments using unsensitized particles.nanoparticles. These data represent the first direct real-time observation of the dynamics of ferrous ion formation and its subsequent transformations in iron oxide.

Therefore, more accurate quantitative and qualitative information about the mechanisms and kinetics of nanoparticle development at surfaces is required. However, direct in situ observations of nanoparticle development have been challenging because of lack of proper tools. In this work, we have used a time-resolved simultaneous small angle X-ray scattering (SAXS)/grazing incidence (GISAXS) setup for real-time monitoring of water-mineral interfacial reactions. The size, shape, and distribution of hydrous ferric oxide nanoparticles on quartz surfaces as well as in solutions and their growth modes were monitored as a function of exposure time, ionic strength, and the presence of arsenate. Nanoparticles formed preferrentially along steps rather than terraces due to highly reactive dangling bonds at steps. Under aqueous conditions, newly formed nanoparticles did not exhibit any facets. However, clear facet formation of ferric oxide nanoparticles at surfaces were observed when they were dried overnight. This implies the importance of in situ observations of hydrous oxide nanoparticles. In the absence of any other metal ions, the earliest nuclei sizes of iron oxides are 1.7 + or - 0.5 nm. On the other hand, the presence of arsenate ions significantly influenced nanoparticle sizes and crystallinities of hydrous nanoparticles and altered the kinetics of the ferric oxide nucleation and growth. For comparison, we conducted complementary measurements of their morphology with atomic force microscopy for interfacial observations, as well as dynamic light scattering and high resolution transmission electron microscopy for particle observations in solutions. Using an environmental in situ time-resolved SAXS/GISAXS setup, this study provides more accurate depiction of evolving nanoparticle distributions and topology at an active interface without dehydration. Our findings have implications not only to hydrous ferric oxide containing biogeochemical systems such as acid mine drainage (AMD) but also to any type of precipitation processes at solid-water interfaces in environmental research.

Such stabilization (or lack of it) can also have a major effect on the nanoparticle structure by affecting the strain profile throughout the particle, and controlling whether structural transformations are readily promoted. Natural nanoparticles may also be stabilized by the presence of a surface layer or thin shell of sorbed ligands, and this study investigated how different ligand types (NaCl, CaCl (sub 2) , Na (sub 2) SO (sub 4) , C (super 6) H (super 6) S, H (super 2) O, C (super 6) H (super 5) Cl, CH (super 3) OH) affected the internal structures and strain in synthetic 3 nm ZnS nanoparticles. The work was in part motivated by several earlier studies of ZnS strain and aggregation-based transformations by Ben Gilbert and colleagues, that indicated the major influence of nanoparticle surface environment [1-3]. Using analysis of the pair-distribution-function (PDF) obtained from high energy x-ray scattering at the Advanced Photon Source, it was found that the stronger the surface ligand or surface complex binding interaction, the larger was the well-defined crystalline core of the nanoparticles, and the thinner the surface shell having high disorder [4]. Analogous molecular dynamics simulations of the ligand-nanoparticle interactions yielded very similar results. Ab initio calculations using a segment of the nanoparticle surface and the sorbed molecular group were used to quantify the interaction strength. The study verified that PDF analysis can ascertain the effect of surface ligand binding on nanoparticle structure, thereby indicating the magnitude of the surface interactions. 1. B. Gilbert, F.

Despite this link to orogenic behavior, difficulties associated with the actual strain measurements have limited the use of strain in interpreting ductile deformation and orogenic kinematics. Here, we develop a new technique to rapidly measure 3D strains directly from a sample's internal volume information, eliminating much of the labor and interpolation associated with traditional 3D strain measurements. Our technique uses an X-ray synchrotron source to image a sample's 3D internal X-ray absorption coefficient at micron resolution. The X-ray absorption coefficient is directly related to atomic number and density, allowing, in this application, quartz grains to be distinguished from overgrowths and selvages. We employ autocorrelation to rapidly and automatically measure the 3D strain from the X-ray absorption information. Here we present X-ray microtomography strain measurements (and provide comparisons with traditional thin-section measurements) for 52 pressure-solved sandstones from the Olympic subduction complex in Washington State. These strain measurements suggest overall vertical extension and sub-horizontal shortening in the direction of convergence for the Olympic subduction complex. This rapid new strain measurement technique will increase both the quality and quantity of strain measurements, leading to improved interpretations of ductile deformation and widespread field-based constraints on orogenic kinematics.

Differential absorption X-ray tomography (DAT) can be used to qualitatively and quantitatively document textures of zircon and REE-minerals in situ and in 3D. The method takes advantage of large jumps in X-ray attenuation near absorption edges to generate 3D elemental maps for selected elements. A key limitation is the strong dependence of the maximum sample diameter on the absorption edge energy. For most major elements in silicate rocks, only sub-mm samples can be imaged. Many elements with higher atomic number (e.g. Sr) appear dispersed in major minerals and are unsuited for DAT. Zr and REE are major components of certain accessory minerals and have absorption edges at energies suitable for imaging samples up to approximately 1 cm in diameter. This is particularly fortunate, given that zircon and REE-minerals preserve rich records of magmatic evolution. We apply DAT to pumice from Peach Spring Tuff (PST) and Mount St. Helens (MSH) and present a few illustrative examples of the kinds of data that can be extracted using a combination of DAT and conventional tomography. Several factors make DAT particularly interesting for studies of accessory minerals: (1) Textures and contact relations between accessory minerals can be documented in 3D, as exemplified by the discovery of numerous zircon crystals included in titanite and in contact with allanite and magnetite in PST pumice; (2) Different populations of accessory minerals can be recognized and studied in textural context, as demonstrated by the identification of two populations of zircon crystals in MSH pumice: a population of zircon crystals included in other minerals, and a population of zircon crystals fully embedded in glass; (3) Crystal size distributions can be readily obtained, and provide information on the crystal nucleation and growth histories, including inferences on the timescales of magmatic crystallization. Particularly when combined with compositional and age data, the ability to visualize and document accessory minerals in 3D and in textural context opens exciting new possibilities for the study of accessory minerals and of the rocks in which they are contained.

WD is caused by mutations in ATP7B and subsequent copper overload. However, copper levels alone do not predict severity of the disease. We demonstrate that temporal and spatial distribution of copper in hepatocytes may play an important role in WD pathology. High resolution synchrotron-based x-ray fluorescence imaging in situ indicates that copper does not continuously accumulate in Atp7b-/- hepatocytes, but reaches a limit at 90-300 fmol. The lack of further accumulation is associated with the loss of copper transporter Ctr1 from the plasma membrane and the appearance of copper-loaded lymphocytes and extracellular copper deposits. The WD progression is characterized by changes in subcellular copper localization and transcriptome remodeling. The synchrotron-based x-ray fluorescence imaging and mRNA profiling both point to the key role of nucleus in the initial response to copper overload and suggest time-dependent sequestration of copper in deposits as a protective mechanism. The metabolic pathways, up-regulated in response to copper, show compartmentalization that parallels changes in subcellular copper concentration. In contrast, significant down-regulation of lipid metabolism is observed at all stages of WD irrespective of copper distribution. These observations suggest new stage-specific as well as general biomarkers for WD. The model for the dynamic role of copper in WD is proposed.

The tank is assumed to be rigid. Critical response quantities for rigid annular tanks are evaluated over wide ranges of parameters involved and the results presented in a form convenient for use in practical applications. The effect of tank flexibility on the response is then assessed by the procedure proposed by Veletsos and Yang (1977). Simple approximation equations for estimating the fundamental frequency of the outer tank wall-liquid and inner tank wall-liquid systems are proposed.

However, seismic and mineral physics observations of the polarized Vs are still emerging. Thus far, the Vs anisotropy of the constitute iron crystals at relevant pressures of the Earth's core has remained mostly theoretical mainly because of the technical difficulties involved in measuring reliable Vs velocities of iron crystals. Here we have measured azimuthal Vs anisotropy of highly textured hcp-Fe at high pressures using nuclear resonant inelastic X-ray scattering, a technique sensitive to Vs, in a diamond anvil cell. Our results show that the azimuthal Vs is 2-4% faster along the crystallographic c axis than along the a axis at 158 GPa and 172 GPa. If one describes the Vp anisotropy of the inner core as a result of the textured hcp-Fe crystals, it is conceivable that azimuthal and polarized Vs anisotropies with a magnitude of a few percent also exist in the region. Since Vp and Vs of candidate iron phases behave quite differently in theoretical predictions, our results here indicate that future seismic observations of the Vs and Vp anisotropies of the inner core thus hold the key to deciphering the causes for the seismic and dynamic signatures as well as constitute iron phase(s) of the region.

The Monte Carlo simulation results are compared with the ICE-Experimental measurements for burnup up to 30GWD/t. The comparison shows the good capabilities of the MCNPX computer code package for predicting the depletion of the uranium fuel and the buildup of the plutonium isotopes in a PWR thermal reactor. The Monte Carlo simulation results show also good agreements with the experimental data for calculating several long-lived and stable fission products. However, for the americium and curium actinides, it is difficult to judge the predication capabilities for these actinides due to the large uncertainties in the ICE-Experimental data. In the MCNPX numerical simulations, a pin cell model is utilized to simulate the fuel lattice of the nuclear power reactor. Temperature dependent libraries based on JEFF3.1 nuclear data files are utilized for the calculations. In addition, temperature dependent libraries based ENDF/B-VII nuclear data files are utilized and the obtained results are very close to the JEFF3.1 results, except for a1410% differences in the prediction of the minor actinide isotopes buildup.

A general theory is that the geography of Europe facilitated the development of diverse and independent states and resultant competition among them. Over the past 500years, the sequence of leading states began with Portugal and the Netherlands on the edge of continental Western Europe, then moved to the British Isles, and finally moved across the Atlantic Ocean to the United States. The transitions of leadership from one state to another occurred about every 100years. This sequence suggests that leadership moves from smaller states to larger states (although not to the largest existing state at the time), perhaps because larger states have the flexibility to develop more complex organizational processes and adapt new technology. To explore this theory further, this paper analyzes state population data at the beginning and end of each leadership period. The data reveal an accelerating initial population sequence. Further understanding is gained from comparing the populations of the preceding and succeeding states at the time of each transition: the succeeding state's population is usually about two times larger than that of the preceding state. It is also seen that over time, the new organizational processes and technologies developed by the leading state are diffused and adapted by other states. Evidence of the effects of this diffusion should be seen in the dynamics of relative productivity and energy use (since the relative advantage of new ideas and technology can be maintained for a short period of about 100years). This paper investigates these trends in population, trade, and resources to provide insight on possible future transitions.

With the addition of an appropriate amount of TOS (no more than 1 wt%) to MCMB/NCM cells, the capacity retention was significantly improved at 55 C compared with cells containing pristine electrolyte. Aging tests at 55 C indicated that the capacity retention of the negative electrode had benefited as a result of the formation of a stable passivation film at the surface of the carbon electrode due to TOS reduction. Electrochemical impedance spectroscopy showed that a TOS addition of more than 0.5 wt% increased the cell interfacial impedance. Differential scanning calorimetry showed that the thermal stability of lithiated MCMB was also improved with the TOS addition.

The initial membrane water content (l, the number of water molecules per sulfonic acid site) is found to be an important parameter that determines whether a successful unassisted self-start is possible. For a given initial subfreezing temperature at startup, there is a critical l (l sub(h)), above which self-start is not possible because the product water completely engulfs the catalyst layers with ice before the stack can warm-up to 0 C. There is a second value of l (l sub(l)), below which the stack can be self-started without forming ice. Between l sub(l) and l sub(h), the stack can be self-started, but with intermediate formation of ice that melts as the stack warms up to 0 C. Both l sub(l) and l sub(h) are functions of the initial stack temperature, cell voltage at startup, membrane thickness, catalyst loading, and stack heat capacity. If the stack is purged during the previous shutdown by flowing air in the cathode passages, then depending on the initial amount of water in the membrane and gas diffusion layers and the initial stack temperature, it may not be possible to dry the membrane to the critical l for a subsequent successful startup. There is an optimum l for robust and rapid startup and shutdown. Startup and shutdown time and energy may be unacceptable if the l is much less than the optimum. Conversely, a robust startup from subfreezing temperatures cannot be assured if the l is much higher than this optimum.

The compounds were fully characterized by super(1)H, super(13)C, and super(29)Si nuclear magnetic resonance (NMR) spectroscopy. Upon doping with lithium bis(oxalato)borate (LiBOB) or LiPF sub(6), the disiloxane electrolytes showed conductivities up to 6.2 x 10 super(-4) S cm super(-1) at room temperature. The thermal behavior of the electrolytes was studied by differential scanning calorimetry, which revealed very low glass transition temperatures before and after LiBOB doping and much higher thermal stability compared to organic carbonate electrolytes. Cyclic voltammetry measurements showed that disiloxane-based electrolytes with 0.8 M LiBOB salt concentration are stable to 4.7 V. The LiBOB/disiloxane combinations were found to be good electrolytes for lithium-ion cells; unlike LiPF sub(6), LiBOB can provide a good passivation film on the graphite anode. The LiPF sub(6)/disiloxane electrolyte was enabled in lithium-ion cells by adding 1 wt% vinyl ethylene carbonate (VEC). Full cell performance tests with LiNi sub(0.80)Co sub(0.15)Al sub(0.05)O sub(2) as the cathode and mesocarbon microbead (MCMB) graphite as the anode show stable cyclability.

This stream is generated during reprocessing of light-water-reactor spent fuel to recycle the actinides and separate fission products for waste disposal. U and Tc are co-extracted from a nitric acid solution using tri-n-butylphosphate in dodecane, so that Tc(VII) is present in the strip solution after the actinide separations. The goal is to separate uranyl from the pertechnetate in this U-Tc stream and then sequester Tc in the metallic form. Our approach is based on reductive stripping of pertechnetate either from aqueous solution (for column extractions) or organic solvents (for liquid-liquid extractions). In both of these methods, metallic zinc in the presence of formic acid serves as a reducing agent, and 99Tc is recovered as a co-precipitate of Zn(II) hydroxide and hydrous Tc(IV) oxide, with a Zn:Tc ratio between 1:1 and 2:1 mol/mol. This solid residue can be reduced to a Zn-Tc alloy by high temperature (500-700 degree C) hydrogenation, and the resulting heterophase alloy can be added to a metallic Fe-Zr-Mo waste form that is processed at 1600 degree C, with subsequent loss of Zn by evaporation. Alternatively, Zn and Tc can be separated and 99Tc sequestered as NH4TcO4 for further reduction to Tc(0) metal. The aqueous Zn reduction process removes similar to 90% of 99Tc per cycle. The nonaqueous Zn reduction in 1:1 methanol - formic acid removes 60-70% of 99Tc per cycle, depending on the extracting agent (such as a tetraalkylammonium nitrate). The extracting agent is recycled in the process. The pertechnetate is extracted from the aqueous phase into 1,2-dichloroethane, which is removed by evaporation and reused. The residue is either calcined and steam reformed to Tc(0) or processed by the nonaqueous Zn reduction method. These methods can be used not only to remove the pertechnetate from the U-Tc product stream, but also to sequester the pertechnetate from aqueous waste streams generated through the processes described in this paper, thereby closing the cycle. The same approaches can be used to close the 99Tc cycle for other methods that are currently being developed at Los Alamos and Argonne National Laboratories.

Insoluble solid organic residues can form by oxidative processes associated with thermochemical sulfate reduction (TSR) as well as by thermal chemical alteration (TCA) of petroleum. TCA may follow non-thermal processes, such as biodegradation and asphaltene precipitation, that produce viscous fluids enriched in polar compounds that are then altered into solid bitumens. It is difficult to distinguish solid bitumen formed by TCA from TSR since both processes occur under relatively high temperatures. The focus of the present work is to characterize solid bitumen samples associated with TSR- or TCA-processes using a combination of solid-state X-ray Photoelectron Spectroscopy (XPS), Sulfur X-ray Absorption Near Edge Structure Spectroscopy (S-XANES), and (super 13) C NMR. Naturally occurring solid bitumens from three locations, Nisku Formation, Brazeau River area (TSR-related); La Barge Field, Madison Formation (TSR-related); and, the Alaskan North Slope, Brooks Range (TCA-related), are compared to solid bitumens generated in laboratory simulations of TSR and TCA. The chemical nature of solid bitumens with respect to organic nitrogen and sulfur can be understood in terms of (1) the nature of hydrocarbon precursor molecules, (2) the mode of sulfur incorporation, and (3) their concentration during thermal stress. TSR-solid bitumen is highly aromatic, sulfur-rich, and nitrogen-poor. These heteroatom distributions are attributed to the ability of TSR to incorporate copious amounts of inorganic sulfur (S/C atomic ratio >0.035) into aromatic structures and to initial low levels of nitrogen in the unaltered petroleum. In contrast, TCA-solid bitumen is derived from polar materials that are initially rich in sulfur and nitrogen. Aromaticity and nitrogen increase as thermal stress cleaves aliphatic moieties and condensation reactions take place. TCA-bitumens from the Brooks Range have <75% aromatic carbon. TCA-bitumens exposed to greater thermal stress can have a higher aromaticity, like that observed in TSR-bitumens. Organic sulfur in TCA-organic solids remains relatively constant with increasing maturation (S/C atomic ratio <0.035) due to offsetting preservation and H (sub 2) S elimination reactions. Although S-XANES and (super 13) C NMR provide information needed to understand changes in structure and reactivity that occur in the formation of petroleum solids, in some cases XPS analysis is sufficient to determine whether a solid bitumen is formed by TCA or TSR.

We find that futures prices tend to be higher than spot prices. The average convenience yield is therefore negative, but varies by season and depends on the storage levels in hydro reservoirs. The average realized return on holding a long position in the futures market is also negative. The negative convenience yield and risk premium contrast empirical findings in most other commodity markets. We argue that differences between the supply and demand sides in terms of risk preferences and the ability to take advantage of short-term price variations can contribute to explain the observed relationship between spot- and futures prices. In addition, our analysis shows that the relationship between spot and futures prices is clearly linked to the physical state of the system, such as hydro inflow, reservoir levels, and demand.

Zinc has been shown to play a key role in differentiation of non-pluripotent cell types, but here its role in hESCs is directly examined. By mapping the distribution of metals in hESCs at high resolution by x-ray fluorescence microprobe (XFM) and by analyzing subcellular metal content, we have found evidence that loss of pluripotency is directly correlated with an increase in nuclear zinc. Zinc elevation not only redefines our understanding of the mechanisms that support pluripotency, but also may act as a biomarker and an intervention point for stem cell differentiation.

AN - 748936556; 20698618 AB - Atomic layer deposition (ALD) is used to deposit ruthenium-platinum nanostructured catalysts using 2,4-(dimethylpentadienyl)(ethylcyclopentadienyl) ruthenium, trimethyl(methylcyclopentadienyl) platinum, and oxygen as precursors. Transmission electron microscopy shows discrete 1.2 nm nanoparticles decorating the surface of the spherical alumina support. The Ru-Pt particles are crystalline and have a crystal structure similar to pure platinum. X-ray fluorescence measurements show that the nanoparticle composition is controlled by the ratio of metal precursor ALD cycles. X-ray absorption spectroscopy at the Ru K-edge indicates a nearest neighbor Ru-Pt interaction consistent with a bimetallic composition. Methanol decomposition reactions further confirm a Ru-Pt interaction and show enhanced methanol conversion for the bimetallic nanoparticles when compared to catalysts comprised of a mixture of pure Pt and Ru nanoparticles of similar loading. These results demonstrate that ALD is a viable technique for synthesizing mixed-metal nanostructures suitable for catalysis and other applications.

Recently, particles of zero-valent iron (ZVI) have been used with limited success for in situ remediation of carbon tetrachloride. We studied a modified microparticulate product that combines controlled-release carbon with ZVI for stimulation of in situ chemical reduction of persistent organic compounds in groundwater. With this product, a number of physical, chemical, and microbiological processes were combined to create very strongly reducing conditions that stimulate rapid, complete dechlorination of organic solvents. In principle, the organic component of ZVI microparticles is nutrient rich and hydrophilic and has high surface area capable of supporting the growth of bacteria in the groundwater environment. In our experiments, we found that as the bacteria grew, oxygen was consumed, and the redox potential decreased to values reaching -600 mV. The small modified ZVI particles provide substantial reactive surface area that, in these conditions, directly stimulates chemical dechlorination and cleanup of the contaminated area without accumulation of undesirable breakdown products. The objective of this work was to evaluate the effectiveness of ZVI microparticles in reducing carbon tetrachloride under laboratory and field conditions. Changes in concentrations and in chemical and physical parameters were monitored to determine the role of the organic products in the reductive dechlorination reaction. Laboratory and field studies are presented.

DBDB can easily dissolve in carbonate-based electrolytes, which facilitates its practical use in lithium-ion batteries; however, it has poor electrochemical stability compared to 2,5-di-tert-butyl-1,4-dimethoxybenzene (DDB). The structures of DBDB and DDB were investigated using X-ray crystallography and density functional calculations. The structures differ in the conformations of the alkoxy bonds probably due to the formation of an intramolecular hydrogen bond in the case of DBDB. We investigated reaction energies for decomposition pathways of neutral DBDB and DDB and their radical cations and found little difference in the reaction energies, although it is clear that kinetically, decomposition of DBDB is more favorable.

The TiO sub(2)-C nanoparticles provide a reversible capacity of [not, vert, similar]200 mAh g super(-1), which exceeds the theoretical capacity of the commercially attractive spinel anode, Li sub(4)Ti sub(5)O sub(12) (175 mAh g super(-1)) and is competitive with the capacity reported for other TiO sub(2) products. The processing method is extremely versatile and has implications for preparing, in a single step, a wide variety of electrochemically active compounds that are coated, in situ, with carbon.

Potentiometric titrations were used to characterize the functional group reactivity of the S. oneidensis cells, and we model the titration data using the same type of non-electrostatic surface complexation approach as was applied to titrations of B. subtilis suspensions by Fein et al. (2005). Similar to the results for B. subtilis, the S. oneidensis cells exhibit buffering behavior from approximately pH 3-9 that requires the presence of four distinct sites, with pK sub(a) values of 3.3 +/- 0.2, 4.8 +/- 0.2, 6.7 +/- 0.4, and 9.4 +/- 0.5, and site concentrations of 8.9(+/-2.6) x 10 super(-5), 1.3(+/-0.2) x 10 super(-4), 5.9(+/-3.3) x 10 super(-5), and 1.1(+/-0.6) x 10 super(-4) moles/g bacteria (wet mass), respectively. The bulk Cd isotherm adsorption data for both species, conducted at pH 5.9 as a function of Cd concentration at a fixed biomass concentration, were best modeled by reactions with a Cd:site stoichiometry of 1:1. EXAFS data were collected for both bacterial species as a function of Cd concentration at pH 5.9 and 10 g/L bacteria. The EXAFS results show that the same types of binding sites are responsible for Cd sorption to both bacterial species at all Cd loadings tested (1-200 ppm). Carboxyl sites are responsible for the binding at intermediate Cd loadings. Phosphoryl ligands are more important than carboxyl ligands for Cd binding at high Cd loadings. For the lowest Cd loadings studied here, a sulfhydryl site was found to dominate the bound Cd budgets for both species, in addition to the carboxyl and phosphoryl sites that dominate the higher loadings. The EXAFS results suggest that both Gram-positive and Gram-negative bacterial cell walls have a low concentration of very high-affinity sulfhydryl sites which become masked by the more abundant carboxyl and phosphoryl sites at higher metal:bacteria ratios. This study demonstrates that metal loading plays a vital role in determining the important metal-binding reactions that occur on bacterial cell walls, and that high affinity, low-density sites can be revealed by spectroscopy of biomass samples. Such sites may control the fate and transport of metals in realistic geologic settings, where metal concentrations are low.

13258747 AB - A multi-atom gas-bubble nucleation mechanism in uranium-alloy nuclear fuel operating in the high-temperature equilibrium gamma phase is proposed based on interpretation of measured intragranular bubble-size distribution data. This model is contrasted with the conventional two-atom nucleation mechanism within the context of a mechanistic calculation of the fission-gas bubble-size distribution. The results of the analysis enable the calculation of safety margins for unrestrained fuel swelling. These safety margins contain an uncertainty primarily tied to uncertainties in the values of the volume and Xe diffusion coefficients.

Here we review the significant progress made in the design and creation of a minimal organism. We discuss how comparative genomes, gene essentiality data, naturally small genomes, and metabolic modeling are all being applied to produce a catalogue of the biological functions essential for life. We compare the minimal gene sets from three published sources with functions identified in 13 existing gene essentiality datasets. We examine how genome-scale metabolic models have been applied to design a minimal metabolism for growth in simple and complex media. Additionally, we survey the progress of efforts to construct a minimal organism, either through implementation of combinatorial deletions in Bacillus subtilis and Escherichia coli or through the synthesis and implantation of synthetic genomes.

We report a strategy for simultaneous extraction of protein with food-grade biobased solvents (ethyl lactate, d-limonene, and distilled methyl esters) and enzymatic saccharification of glucan in DGS. This approach would produce a high-value animal feed while simultaneously producing additional sugars for ethanol production. Preliminary experiments on protein extraction resulted in recovery of 15-45% of the protein, with hydrophobic biobased solvents obtaining the best results. The integrated hydrolysis and extraction experiments showed that biobased solvent addition did not inhibit hydrolysis of the cellulose. However, only 25-33% of the total protein was extracted from DGS, and the extracted protein largely resided in the aqueous phase, not the solvent phase. We hypothesize that the hydrophobic solvent could not access the proteins surrounded by the aqueous phase inside the fibrous structure of DGS due to poor mass transfer. Further process improvements are needed to overcome this obstacle.

The temporal variation of temperature required for the computation of the reaction rate constants is obtained from the solution of the energy equation. NO sub(x)formation is modeled by using a six step mechanism with eight species instead of the traditional equilibrium calculations based on the Zeldovich mechanism. Fuel combustion chemistry is modeled by a single-step global reaction. Effects of various stages of combustion on NO sub(x)formation is included using a phenomenological burning rate model. The effects of composition and temperature on the thermophysical properties of the working fluid are included in the computations. Comparison with measured single-cylinder engine-out NO shows good agreement with experimental data. The validated model is then used to demonstrate the impact of various operating parameters such as injection timing and EGR on engine-out NO sub(x) This fast, robust model has potential applications in model-based real-time control strategies seeking to reduce feed gas NO sub(x)emissions from diesel engines.

13314831 AB - The SEED integrates many publicly available genome sequences into a single resource. The database contains accurate and up-to-date annotations based on the subsystems concept that leverages clustering between genomes and other clues to accurately and efficiently annotate microbial genomes. The backend is used as the foundation for many genome annotation tools, such as the Rapid Annotation using Subsystems Technology (RAST) server for whole genome annotation, the metagenomics RAST server for random community genome annotations, and the annotation clearinghouse for exchanging annotations from different resources. In addition to a web user interface, the SEED also provides Web services based API for programmatic access to the data in the SEED, allowing the development of third-party tools and mash-ups. The currently exposed Web services encompass over forty different methods for accessing data related to microbial genome annotations. The Web services provide comprehensive access to the database back end, allowing any programmer access to the most consistent and accurate genome annotations available. The Web services are deployed using a platform independent service-oriented approach that allows the user to choose the most suitable programming platform for their application. Example code demonstrate that Web services can be used to access the SEED using common bioinformatics programming languages such as Perl, Python, and Java. We present a novel approach to access the SEED database. Using Web services, a robust API for access to genomics data is provided, without requiring large volume downloads all at once. The API ensures timely access to the most current datasets available, including the new genomes as soon as they come online.

The real-time XR measurements show characteristic intensity oscillations as a function of time indicative of the successive removal of individual layers. The dissolution rate in 0.01 m NaOH increases approximately linearly with increasing NaCl concentration up to 2m NaCl. XRIM measurements of the lateral interfacial topography/structure were made for unreacted surfaces and those reacted in 0.01 m NaOH/1.0 m NaCl solution for 15, 30 and 58 min. The XRIM images reveal that the dissolution reaction leads to the formation of micron-scale regions that are characterized by intrinsically lower reflectivity than the unreacted regions, and appears to be nucleated at steps and defect sites. The reflectivity signal from these reacted regions in the presence of NaCl in solution is significantly lower than that calculated from an idealized layer-by-layer dissolution process, as observed previously in 0.1 m NaOH in the absence of added electrolyte. This difference suggests that dissolved NaCl results in a higher terrace reactivity leading to a more three-dimensional process, consistent with the real-time XR measurements. These observations demonstrate the feasibility of XRIM to gain new insights into processes that control interfacial reactivity, specifically the role of electrolytes in feldspar dissolution at alkaline conditions.

Electron-microprobe-derived compositions show up to 5.39 wt.% FeO in the darkest material, which is among the highest Fe concentration known for true beryl. The Al site totals average 2.05, with a maximum of 2.10 apfu, which implies that there is more Fe present in the sample than can be accommodated at the Al position. Charge-balance considerations and Mossbauer spectra show that the Fe is present as both Fe (super 2+) and Fe (super 3+) . Optical absorption and Mossbauer spectra and the results of the X-ray and neutron single-crystal refinements suggest that there is very little Fe at the tetrahedral or channel sites. Previous investigators have proposed that the color of blue beryl is due to intervalence charge-transfer (IVCT) between Fe (super 2+) and Fe (super 3+) cations. The anisotropy of the optical absorption spectra suggest that if the mechanism responsible for the color in our samples is IVCT, the vector between the ions involved must be oriented approximately parallel to c. The only vectors that fulfill this condition and have a realistic length (2.300 Aa) are 4d-Al and 6g-Be. Given the close proximity of the Si positions (closer than any anion sites), it is difficult to conceive of the substitution taking place at the interstitial 4d site. However, Fe could substitute at the interstitial 6g position, but likely only in very small amounts, because of the need to maintain local charge-balance. Unfortunately, there is no evidence of this in the Mossbauer spectra or in difference-Fourier maps of the X-ray- and neutron-diffraction data. For the former technique, it is likely that any doublet arising from Fe in the 6gO (sub 6) polyhedron is too similar to the Fe in the AlO (sub 6) octahedra to be resolved for either Fe (super 2+) or Fe (super 3+) . Calculations suggest that the concentration of Fe involved in the IVCT process is 0.08 apfu Fe, of which half (0.04 apfu, 0.17 e (super -) ) would potentially be at the interstitial site. This amount of electrons and this nuclear density are likely too small to be seen on the difference-Fourier maps.

Future U.S. Water Consumption: The Role of Energy Production. Journal of the American Water Resources Association (JAWRA) 46(3):447-460. DOI: 10.1111/j.1752-1688.2009.00413.x Abstract: This study investigates how meeting domestic energy production targets for both fossil and renewable fuels may affect future water demand. It combines projections of energy production developed by the U.S. Department of Energy with estimates of water consumption on a per-unit basis (water-consumption coefficients) for coal, oil, gas, and biofuels production, to estimate and compare the domestic freshwater consumed. Although total domestic freshwater consumption is expected to increase by nearly 7% between 2005 and 2030, water consumed for energy production is expected to increase by nearly 70%, and water consumed for biofuels (biodiesel and ethanol) production is expected to increase by almost 250%. By 2030, water consumed in the production of biofuels is projected to account for nearly half of the total amount of water consumed in the production of all energy fuels. Most of this is for irrigation, and the West North Central Region is projected to consume most of this water in 2030. These findings identify an important potential future conflict between renewable energy production and water availability that warrants further investigation and action to ensure that future domestic energy demand can be met in an economically efficient and environmentally sustainable manner.

Comparison of predicted radionuclide concentrations in the different species types with measured values highlighted a number of areas where additional work and understanding is required to improve the predictions of radionuclide transfer. For some species, the differences could be explained by ecological factors such as trophic level or the influence of stable analogues. Model predictions were relatively poor for mammalian species and herpetofauna compared with measured values, partly due to a lack of relevant data. In addition, concentration ratios are sometimes under-predicted when derived from experiments performed under controlled laboratory conditions representative of conditions in other water bodies.

A number of approaches have been developed for estimating the exposure of wildlife and some of these are being used to conduct regulatory assessments. There is a requirement to compare the outputs of such approaches against available data sets to ensure that they are robust and fit for purpose. In this paper we describe the application of seven approaches for predicting the whole-body ( super(90)Sr, super(137)Cs, super(241)Am and Pu isotope) activity concentrations and absorbed dose rates for a range of terrestrial species within the Chernobyl exclusion zone. Predictions are compared against available measurement data, including estimates of external dose rate recorded by thermoluminescent dosimeters attached to rodent species. Potential reasons for differences between predictions between the various approaches and the available data are explored.

Although the modifications did not change the crystallographic structure of the surface-modified samples, they exhibited better cyclability at elevated temperature (55 degree C) compared with pristine LiNi sub(0.5)Mn sub(1.5)O sub(4). The material that was surface modified with ZrO sub(2) gave the best cycling performance, only 4% loss of capacity after 150 cycles at 55 degree C. Electrochemical impedance spectroscopy demonstrated that the improved performance of the ZrO sub(2)-surface-modified LiNi sub(0.5)Mn sub(1.5)O sub(4) is due to a small decrease in the charge transfer resistance, indicating limited surface reactivity during cycling. Differential scanning calorimetry showed that the ZrO sub(2)-modified LiNi sub(0.5)Mn sub(1.5)O sub(4) exhibits lower heat generation and higher onset reaction temperature compared to the pristine material. The excellent cycling and safety performance of the ZrO sub(2)-modified LiNi sub(0.5)Mn sub(1.5)O sub(4) electrode was found to be due to the protective effect of homogeneous ZrO sub(2) nano-particles that form on the LiNi sub(0.5)Mn sub(1.5)O sub(4), as shown by transmission electron microscopy.

This photoreaction is initiated by the absorption of UVA light, and it readily occurs even at low temperature. The decarboxylation is observed for miscellaneous organic carboxylates, including the nonvolatile products of kerogen oxidation (that are currently thought to accumulate in the soil) as well as alpha -amino acids and peptides. Our study indicates that there may be no "safe haven" for these organic compounds on Mars; oxidation by reactive radicals, such as hydroxyl, is concerted with photocatalytic reactions on the oxide particles. Acting together, these two mechanisms result in mineralization of the organic component. The photooxidation of acetate (the terminal product of radical oxidation of the aliphatic component of kerogen) on the iron(III) oxides results in the formation of methane; this reaction may account for seasonably variable production of methane on Mars. The concomitant reduction of Fe(III) in the regolith leads to the formation of highly soluble ferrous ions that contribute to weathering of the soil particles.

12975163 AB - Biosynthesis of lysine and meso-diaminopimelic acid in bacteria provides essential components for protein synthesis and construction of the bacterial peptidoglycan cell wall. The dapE operon enzymes synthesize both meso-diaminopimelic acid and lysine and, therefore, represent potential targets for novel antibacterials. The dapE-encoded N-succinyl-l,l-diaminopimelic acid desuccinylase functions in a late step of the pathway and converts N-succinyl-l,l-diaminopimelic acid to l,l-diaminopimelic acid and succinate. Deletion of the dapE gene is lethal to Helicobacter pylori and Mycobacterium smegmatis, indicating that DapE's are essential for cell growth and proliferation. Since there are no similar pathways in humans, inhibitors that target DapE may have selective toxicity against only bacteria. A major limitation in developing antimicrobial agents that target DapE has been the lack of structural information. Herein, we report the high-resolution X-ray crystal structures of the DapE from Haemophilus influenzae with one and two zinc ions bound in the active site, respectively. These two forms show different activity. Based on these newly determined structures, we propose a revised catalytic mechanism of peptide bond cleavage by DapE enzymes. These structures provide important insight into catalytic mechanism of DapE enzymes as well as a structural foundation that is critical for the rational design of DapE inhibitors.

Although most Ti(IV) oxides are poor electronic conductors, new methods developed to synthesize nanometer scale primary particles have achieved the higher rate capability needed for modern commercial applications. In this report, the anionic water stable titanium oxalate anion [TiO(C sub(2)O sub(4)) sub(2)] super(2-) was isolated in high yield as the insoluble DABCO (1,4-diazabicyclo[2.2.2]octane) salt. Powder X-ray diffraction studies show that the titanium dioxide material isolated after annealing in air is initially amorphous, converts to N-doped anatase above 400 degree C, then to rutile above 600 degree C. Electrochemical studies indicate that the amorphous titanium dioxide phase within a carbon matrix has a stable cycling capacity of [not, vert, similar]350 mAh g super(-1). On crystallizing at 400 degree C to a carbon-coated anatase the capacity drops to 210 mAh g super(-1), and finally upon carbon burn-off to 50 mAh g super(-1). Mixtures of the amorphous titanium dioxide and Li sub(4)Ti sub(5)O sub(12) showed a similar electrochemical profile and capacity to Li sub(4)Ti sub(5)O sub(12) but with the addition of a sloping region to the end of the discharge curve that could be advantageous for determining state-of-charge in systems using Li sub(4)Ti sub(5)O sub(12).

This paper discusses the role of demand response (DR) as an integral component in alleviating the problem and coping with this shortfall. It reviews current experience with DR programs, analyzes China's situation and makes suggestions for DR implementation. Although China's DR programs offer high potential to succeed, they require substantial efforts in resolving such key issues as the programs' funding mechanisms, pricing, and relationship with electricity industry reform.

Long-term cultivation has depleted substantial soil organic matter (SOM) stocks that once existed in the region's native ecosystems. In central Illinois, free-air CO2 enrichment technology was used to investigate the effects of elevated [CO2] on SOM pools in a conservation tilled corn-soybean rotation. After 5 and 6 y of CO2 enrichment, we investigated the distribution of C and N among soil fractions with varying ability to protect SOM from rapid decomposition. None of the isolated C or N pools, or bulk-soil C or N, was affected by CO2 treatment. However, the site has lost soil C and N, largely from unprotected pools, regardless of CO2 treatment since the experiment began. These findings suggest management practices have affected soil C and N stocks and dynamics more than the increased inputs from CO2-stimulated photosynthesis. Soil carbon from microaggregate-protected and unprotected fractions decreased in a conservation tilled corn-soybean rotation despite increases in primary production from exposure to atmospheric CO2 enrichment.

The protein was crystallized using reagents prepared in D sub(2)O. About 86% of the amide hydrogen atoms are either partially or fully exchanged, which correlates well with the atomic depth of the amide nitrogen atom and the secondary structure type, but with notable exceptions. Each of the four residues that provide copper ligands is partially deuterated. The model reveals the dynamic nature of the protein, especially around the copper-binding site. A detailed analysis of the presence of deuterated water molecules near the exchange sites indicates that amide hydrogen exchange is primarily due to the flexibility of the protein. Analysis of the electron transfer path through the protein shows that residues in that region are highly dynamic, as judged by hydrogen/deuterium exchange. This could increase the rate of electron transfer by transiently shortening through-space jumps in pathways or by increasing the atomic packing density. Analysis of C-Ha<[macr]X bonding reveals previously undefined roles of these relatively weak H bonds, which, when present in sufficient number can collectively influence the structure, redox, and electron transfer properties of amicyanin.

AN - 733532275; 20195017 AB - Palladium has been extensively studied as a material for hydrogen sensors because of the simplicity of its reversible resistance change when exposed to hydrogen gas. Various palladium films and nanostructures have been used, and different responses have been observed with these diverse morphologies. In some cases, such as with nanowires, the resistance will decrease, whereas in others, such as with thick films, the resistance will increase. Each of these mechanisms has been explored for several palladium structures, but the crossover between them has not been systematically investigated. Here we report on a study aimed at deciphering the nanostructure-property relationships of ultrathin palladium films used as hydrogen gas sensors. The crossover in these films is observed at a thickness of approximately 5 nm. Ramifications for future sensor developments are discussed.

AN - 733342001; 20121062 AB - Critical photonic, electronic, and magnetic applications of two-dimensional nanocrystal superlattices often require nanostructures in perfect single-crystal phases with long-range order and limited defects. Here we discovered a crystalline phase with quasi-long-range positional order for two-dimensional nanocrystal superlattice domains self-assembled at the liquid-air interface during droplet evaporation, using in situ time-resolved X-ray scattering along with rigorous theories on two dimensional crystal structures. Surprisingly, it was observed that drying these superlattice domains preserved only an orientational order but not a long-range positional order, also supported by quantitative analysis of transmission electron microscopy images.

X-ray reflectivity measurements indicated that Fe(II) induces changes in the structure of all three surfaces under both acidic (pH 3) and neutral (pH 7) conditions. The structural changes were generally independent of pH although the extent of surface transformation varied slightly between acidic and neutral conditions; no systematic trends with pH were observed. Induced changes on the (110) and (012) surfaces include the addition or removal of partial surface layers consistent with either growth or dissolution. In contrast, a <1 nm thick, discontinuous film formed on the (001) surface that appears to be epitaxial yet is not a perfect extension of the underlying hematite lattice, being either structurally defective, compositionally distinct, or nanoscale in size and highly relaxed. Resonant anomalous X-ray reflectivity measurements determined that the surface concentration of Fe(II) present after reaction at pH 7 was below the detection limit of approximately 0.5-1 mu mol/m (super 2) on all surfaces. These observations are consistent with Fe(II) oxidative adsorption, whereby adsorbed Fe(II) is oxidized by structural Fe(III) in the hematite lattice, with the extent of this reaction controlled by surface structure at the atomic scale. The observed surface transformations at pH 3 show that Fe(II) oxidatively adsorbs on hematite surfaces at pH values where little net adsorption occurs, based on historical macroscopic Fe(II) adsorption behavior on fine-grained hematite powders. This suggests that Fe(II) plays a catalytic role, in which an electron from an adsorbed Fe(II) migrates to and reduces a lattice Fe(III) cation elsewhere, which subsequently desorbs in a scenario with zero net reduction and zero net adsorption. Given the general pH-independence and substantial mass transfer involved, this electron and atom exchange process appears to be a significant subsystem within macroscopic pH-dependent Fe(II) adsorption.

The total amount of Sr (super 2+) adsorbed from a 1 x 10 (super -2) mol/kg SrCl (sub 2) and 100 mg/kg Elliott Soil Fulvic Acid II (ESFA II) solution at pH 5.5 compensated 81 + or - 5% of the muscovite surface charge, less than previously measured (118 + or - 5%) in an ESFA II-free solution with the same Sr concentration and pH. Inner-sphere (IS) and outer-sphere (OS) Sr (super 2+) constituted 87% of the total adsorbed species in IS:OS proportions of 19:81 compared to 42:58 in the solution without FA, suggesting that adsorbed FA competes with the IS Sr (super 2+) for surface sites. The coverage of both IS and OS Sr (super 2+) decreased even more in a pH 3.5 solution containing the same concentration of FA and 0.5 x 10 (super -2) mol/kg Sr(NO (sub 3) ) (sub 2) , whereas a significant amount of Sr (super 2+) accumulated farther from the surface in the FA layer. The amount of Sr (super 2+) incorporated in the nearly equal 10A thick FA layer decreased by 79% with decreasing FA concentration (100 --> 1 mg/kg) and increasing Sr (super 2+) concentration (0.5 x 10 (super -2) --> 1 x 10 (super -2) mol/kg) and pH (3.5 --> 3.6). These results indicate not only that adsorbed FA molecules (and perhaps also H (sub 3) O (super +) ) displace Sr (super 2+) near the muscovite surface, but also that the sorbed FA film provides binding sites for additional Sr (super 2+) away from the surface. When a muscovite crystal pre-coated with FA after reaction in a 100 mg/kg ESFA II solution for 50 h was subsequently reacted with a 0.5 x 10 (super -2) mol/kg Sr(NO (sub 3) ) (sub 2) and 100 mg/kg ESFA II solution at pH 3.7, a significant fraction of Sr (super 2+) was distributed in the outer part of the FA film similar to that observed on fresh muscovite reacted at pH 3.5 with a pre-mixed Sr-FA solution at the same concentrations. However, this Sr (super 2+) sorbed in the pre-adsorbed organic film was more widely distributed and had a lower coverage, suggesting that pre-sorbed FA may undergo fractionation and/or conformational changes that diminish its capacity, and that of the muscovite (001) surface, for adsorbing the aqueous Sr cation.

13268742 AB - Biogenic FeII phases (magnetite, green rust, siderite, vivianite, etc.) provide a reservoir of reducing capacity in many subsurface environments that may contribute to the reduction of contaminants such as UVI. We have examined the uptake and reduction of UVI in the presence of biogenic green rust (BioGR), magnetite (BioMAG), and siderite (BioSID) formed during the reduction of FeIII oxides by Shewanella putrefaciens CN32. Within 48 h, total solution-phase UVI concentrations decreased from 500*mM to 1.5*mM, 392*mM, and 472*mM in the U-BioGR, U-BioMAG, and U-BioSID systems, respectively. Analysis of the samples by U LIII extended X-ray absorption fine structure spectroscopy (EXAFS) indicated that despite a stoichiometric excess of FeII, no more than 6% of UVI was reduced to UIV in the U-BioSID system, and no more than 22% of UVI was reduced in the U-BioMAG system. For comparison, in the U-BioGR system, >99% of UVI was reduced to UIV. Uptake of UVI by BioGR and BioMAG was accompanied by formation of nanoparticulate uraninite. The U EXAFS data for the U-BioSID system were consistent with partial UVI/UIV substitution for FeII in the surface layer of siderite particles and adsorption of UIV.

Our diffraction measurements revealed that the incorporation of Fe (super 3+) has virtually no effect on the volume of PPv, in contrast to Fe (super 2+) , which increases the volume. Therefore, incorporation of Fe (super 3+) increases the density of PPv much more effectively than Fe (super 2+) . Moessbauer spectroscopy suggests that Fe (super 3+) enters PPv through charge-coupled substitution and is high spin in the bipolar prismatic site and low spin in the octahedral site (i.e., mixed spin state). Our results may have important implications for the gravitational stability of lower-mantle heterogeneities.

Most experimental works so far have used superparamagnetic materials. This report describes a first approach based on interfacing cells with lithographically defined microdiscs that possess a spin-vortex ground state. When an alternating magnetic field is applied the microdisc vortices shift, creating an oscillation, which transmits a mechanical force to the cell. Because reduced sensitivity of cancer cells toward apoptosis leads to inappropriate cell survival and malignant progression, selective induction of apoptosis is of great importance for the anticancer therapeutic strategies. We show that the spin-vortex-mediated stimulus creates two dramatic effects: compromised integrity of the cellular membrane, and initiation of programmed cell death. A low-frequency field of a few tens of hertz applied for only ten minutes was sufficient to achieve similar to 90% cancer-cell destruction in vitro.

Thus, in addition to conventional recycling facilities for polymer waste (PW), innovative solutions are required. This paper describes a solvent-free process that converts PW such as low-density (LD) and high-density polyethylene (HDPE) into multi-walled carbon nanotubes (MWCNTs) via thermal dissociation in the presence of chemical catalysts in a closed system under autogenic pressure. Specifically, the optimization of process parameters, e.g. selection and amounts of catalysts, density effects of PE, autogenic pressure measurements, and a reaction mechanism for the growth of MWCNTs is explained. The composition, morphology, and atomic structure of the as-obtained MWCNTs are characterized employing advanced structural, spectroscopic, and imaging techniques. We have measured the unique magnetic and electrical conductivity behaviours of as-prepared MWCNTs to assess their potential applications as advanced materials. This reproducible process presents an opportunity to use PW as a feedstock for the production of MWCNTs, industrially significant value-added products. Among the known methods for the fabrication of MWCNTs, the present controlled dissociation of PW is one of the inexpensive and straightforward methods.

However, it may result from many different mechanisms, some requiring direct cell contact and others resulting from the diffusion of reactive species in solution. Published results are contradictory due to differences in particle preparation, bacterial strain, and experimental conditions. It has been recently found that C60 nanoparticles can cause direct oxidative damage to bacterial proteins and membranes, including causing a loss of cell membrane potential (depolarization). However, this did not correlate with toxicity. In this study we perform a similar analysis using fluorescent CdTe quantum dots, adapting our tools to make use of the particles' fluorescence. We find that two Gram positive strains show direct electron transfer to CdTe, resulting in changes in CdTe fluorescence lifetimes. These two strains also show changes in membrane potential upon nanoparticle binding. Two Gram negative strains do not show these effects--nevertheless, they are over 10-fold more sensitive to CdTe than the Gram positives. We find subtoxic levels of Cd2+ release from the particles upon irradiation of the particles, but significant production of hydroxyl radicals, suggesting that the latter is a major source of toxicity. These results help establish mechanisms of toxicity and also provide caveats for use of certain reporter dyes with fluorescent nanoparticles which will be of use to anyone performing these assays. The findings also suggest future avenues of inquiry into electron transfer processes between nanomaterials and bacteria.

Rietveld refinement of the X-ray diffraction patterns revealed that our sample was dominated by CaIrO (sub 3) -type post-perovskite. Combined Moessbauer and X-ray emission results show that Fe in post-perovskite is predominantly Fe (super 2+) (70%) in the intermediate-spin state with extremely high quadrupole splitting of 3.77(25) mm/s. The remaining 30% Fe can be assigned to two sites. Compared with recent studies, our results indicate that the intermediate-spin Fe (super 2+) is stabilized in CaIrO (sub 3) -type post-perovskite over a wide range of Fe content, whereas the low-spin Fe (super 3+) is more dominant in the 2 X 1 kinked post-perovskite structure. The characterization of these structural and compositional effects on the spin and valence states of Fe in post-perovskite can help in understanding the geochemical and geophysical behavior of the core-mantle region.

The effect of electronic environment of the iron sites on the sound velocities were tracked in situ using synchrotron Moessbauer spectroscopy. We found the sound velocities of (Mg (sub .16) Fe (sub .84) )O to be much lower than those in other presumed mantle phases at similar conditions, most notably at very high pressures. Conservative estimates of the effect of temperature and dilution on aggregate sound velocities show that only a small amount of iron-rich (Mg,Fe)O can greatly reduce the average sound velocity of an assemblage. We propose that iron-rich (Mg,Fe)O be a source of ultra-low velocity zones. Other properties of this phase, such as enhanced density and dynamic stability, strongly support the presence of iron-rich (Mg,Fe)O in localized patches above the core-mantle boundary.

On an annual basis, natural sources account for 5207 Mg of mercury released to the global atmosphere, including the contribution from re-emission processes, which are emissions of previously deposited mercury originating from anthropogenic and natural sources, and primary emissions from natural reservoirs. Anthropogenic sources, which include a large number of industrial point sources, are estimated to account for 2320 Mg of mercury emitted annually. The major contributions are from fossil-fuel fired power plants (810 Mg yr (super -1) ), artisanal small scale gold mining (400 Mg yr (super -1) ), non-ferrous metals manufacturing (310 Mg yr (super -1) ), cement production (236 Mg yr (super -1) ), waste disposal (187 Mg yr (super -1) ) and caustic soda production (163 Mg yr (super -1) ). Therefore, our current estimate of global mercury emissions suggests that the overall contribution from natural sources (primary emissions+re-emissions) and anthropogenic sources is nearly 7527 Mg per year, the uncertainty associated with these estimates are related to the typology of emission sources and source regions.

A simplified phase diagram for the pentanary system comprised of H3PW12O40, HNO3, H2O, TBP, and n-octane reveals an extremely low initial concentration of H3PW12O40 (1.1mM) at the LOC (limiting organic concentration) condition, far lower than the most effective third-phase-forming inorganic acid, namely HClO4. The results from small-angle neutron scattering (SANS) indicate that the interparticle attraction energy--U(r) calculated through application of the Baxter sticky sphere model to the SANS data at the LOC condition--does not approach the -2 kBT value associated with phase splitting in previous studies of TBP third-phase formation. The third-phase formation model based on attractive interactions between polar cores of reverse micelles, successfully developed for TBP and other extraction systems does not apply to the extraction of H3PW12O40. Rather, the separation of a third-phase from the TBP organic phase stems from the limited solubility of the heavy and highly polar H3PW12O40-TBP species in the alkane diluent.

No formation of a heavy organic phase (third phase) was observed with TEHP and TOP under the experimental conditions used, whereas for 0.4M TOPO the HCl limiting organic concentration (LOC) at 23 degree C was 0.32M (with 5.1M HCl in the equilibrium aqueous phase). For higher HCl concentrations in the aqueous phase, the organic phase splits into a light and a heavy layer. For TEHP and TOP, the SANS results, interpreted using the Baxter model for hard spheres with surface adhesion, indicated the formation of only small reverse micelles with little intermicellar attraction. For TOPO, the scattering signals suggested the formation of much larger and strongly interacting micelles. The critical values of the stickiness parameter, tau -1, and the interaction potential energy, U(r), for the LOC sample in the TOPO system were consistent with the model for third-phase formation previously developed for tri-n-butyl phosphate (TBP). According to this model, organic phase splitting is due to van der Waals interactions between the polar cores of reverse micelles formed by the extractants in the organic phase.

We set up a series of increasingly complex models with such features as learning-by-doing, adjustment cost, and capital investment. The models are written in continuous time and then discretised by using different methods to transform them into large-scale non-linear programs. We use a modelling language and numerical optimisation methods to solve the optimisation problem. Our results are consistent with findings in the literature and highlight the impact the discretisation choice has on the solution and accuracy.

The system, developed by the PCP team at Argonne National Laboratory, involves hardware modification, application software development, secured database and web server development, and irradiation experiments. In April 2008, Argonne tested key features of the RFID tracking and monitoring system in a weeklong, 1700 mile (2736 km) demonstration employing 14 empty type B fissile material drums of three designs (models 9975, 9977 and ES-3100) that have been certified for shipment by the DOE and the US Nuclear Regulatory Commission. The demonstration successfully integrated global positioning system (GPS) technology for vehicle tracking, satellite/cellular (general packet radio service, or GPRS) technologies for wireless communication, and active RFID tags with multiple sensors (seal integrity, shock, temperature, humidity and battery status) on drums. In addition, the demonstration integrated geographic information system (GIS) technology with automatic alarm notifications of incidents and generated buffer zone reports for emergency response and management of staged incidents. The demonstration was sponsored by EM and the US National Nuclear Security Administration, with the participation of Argonne, Savannah River and Oak Ridge National Laboratories. Over 50 authorised stakeholders across the country observed the demonstration via secured Internet access. The DOE PCP and national laboratories are working on several RFID system implementation projects at selected DOE sites, as well as continuing device and systems development and widening applications beyond DOE sites and possibly beyond nuclear materials to include other radioactive materials.

DO - http://dx.doi.org/10.1179/174650910X12628787557739 ER - TY - JOUR T1 - Spin state of ferric iron in MgSiO (sub 3) perovskite and its effect on elastic properties AN - 742906654; 2010-047593 AB - Recent studies have indicated that a significant amount of iron in MgSiO (sub 3) perovskite (Pv) is Fe (super 3+) (Fe (super 3+) /Sigma Fe = 10-60%) due to crystal chemistry effects at high pressure (P) and that Fe (super 3+) is more likely than Fe (super 2+) to undergo a high-spin (HS) to low-spin (LS) transition in Pv in the mantle. We have measured synchrotron Mossbauer spectroscopy (SMS), X-ray emission spectroscopy (XES), and X-ray diffraction (XRD) of Pv with all iron in Fe (super 3+) in the laser-heated diamond-anvil cell to over 100 GPa. Fe (super 3+) increases the anisotropy of the Pv unit cell, whereas Fe (super 2+) decreases it. In Pv synthesized above 50 GPa, Fe (super 3+) enters into both the dodecahedral (A) and octahedral (B) sites approximately equally, suggesting charge coupled substitution. Combining SMS and XES, we found that the LS population in the B site gradually increases with pressure up to 50-60 GPa where all Fe (super 3+) in the B site becomes LS, while Fe (super 3+) in the A site remains HS to at least 136 GPa. Fe (super 3+) makes Pv more compressible than Mg-endmember below 50 GPa because of the gradual spin transition in the B site together with lattice compression. The completion of the spin transition at 50-60 GPa increases bulk modulus with no associated change in density. This elasticity change can be a useful seismic probe for investigating compositional heterogeneities associated with Fe (super 3+) .

Synthetic rutile and natural cassiterite, with 0.1-0.2 wt% impurities, remain crystalline up to a fluence of 5X10 (super 15) ions cm (super -2) without evidence for amorphization at 50 K. Natural brookite and anatase, with 0.3-0.5 wt% impurities, become amorphous at fluences of 8.1X10 (super 14) and 2.3X10 (super 14) ions cm (super -2) , respectively. We have also studied two natural rutile samples containing approximately 1.7 and 1.2 wt% impurities. These samples became amorphous at 9.2X10 (super 14) and 8.6X10 (super 14) ions cm (super -2) at 50 K, respectively. Further analyses of the fluence-temperature data for natural brookite, rutile, and anatase give critical amorphization temperatures of 168+ or -11, 209+ or -8, and 242+ or -6 K, respectively. Results are briefly discussed with respect to several criteria for radiation resistance, including aspects of the structure, bonding, and energetics of defect formation and migration.

These peptides fall structurally into three different classes, I, II, III, with class IIa being pediocin-like single entities and class IIb being two-peptide bacteriocins. Self-protective cognate immunity proteins are usually co-transcribed with these toxins. Several examples of cognates for IIa have already been solved structurally. Streptococcus pyogenes, closely related to LAB, is one of the most common human pathogens, so knowledge of how it competes against other LAB species is likely to prove invaluable. We have solved the crystal structure of the gene-product of locus Spy_2152 from S. pyogenes, (PDB:2fu2), and found it to comprise an anti-parallel four-helix bundle that is structurally similar to other bacteriocin immunity proteins. Sequence analyses indicate this protein to be a possible immunity protein protective against class IIa or IIb bacteriocins. However, given that S. pyogenes appears to lack any IIa pediocin-like proteins but does possess class IIb bacteriocins, we suggest this protein confers immunity to IIb-like peptides. Combined structural, genomic and proteomic analyses have allowed the identification and in silico characterization of a new putative immunity protein from S. pyogenes, possibly the first structure of an immunity protein protective against potential class IIb two-peptide bacteriocins. We have named the two pairs of putative bacteriocins found in S. pyogenes pyogenecin 1, 2, 3 and 4.

enabling geosciences gateways to cyberinfrastructure AN - 753849258; 2010-067473 AB - Cyberinfrastructure science and engineering gateways have become an important modality to connect science and engineering communities and cyberinfrastructure. The use of cyberinfrastructure through gateways is fundamental to the advancement of science and engineering. However, learning science gateway technologies and developing science gateways remain a significant challenge, given that science gateway technologies are still actively evolving and often include a number of sophisticated components. A geosciences gateway must be designed to accommodate legacy methods that geoscientists use in conventional computational tools. The research described in this paper establishes an open-source toolkit-SimpleGrid for learning and developing science gateways based on a service-oriented architecture using a component-based approach that allows flexible separation and integration of the components between geocomputation applications and cyberinfrastructure.

SEM analysis of scaffolds showed random nanofibrous morphology and well-interconnected pore network. Due to protein blending, the fiber diameter was reduced from 800-950 nm range to 300-500 nm range. Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) results confirmed the blended composition and crystallinity of fibers. Pure PDS scaffold under hydrated state exhibited a tensile strength of 5.61 ? 0.42 MPa and a modulus of 17.11 ? 1.13 MPa with a failure strain of 216.7 ? 13%. The blending of PDS with elastin and gelatin has decreased the tensile properties. A trilayer tubular scaffold was fabricated by sequential electrospinning of blends of elastin/gelatin, PDS/elastin/gelatin, and PDS/gelatin (EG/PEG/PG) to mimic the complex matrix structure of native arteries. Under hydrated state, the trilayer conduit exhibited tensile properties (tensile strength of 1.77 ? 0.2 MPa and elastic modulus of 5.74 ? 3 MPa with a failure strain of 75.08 ? 10%) comparable to those of native arteries. In vitro degradation studies for up to 30 days showed about 40% mass loss and increase in crystallinity due to the removal of proteins and cleavage-induced crystallization of PDS. Biotechnol.

However, recent experimental evidence of fluctuating DO concentrations near the sediment-water interface suggests that turbulence and coherent motions control the mass transfer, and the surface renewal theory gives a more mechanistic model for quantifying fluxes. Both models involve quantifying the mass transfer coefficient (k) and the relevant concentration difference ( c). This study compared several empirical models for quantifying k based on both thin-film and surface renewal theories, as well as presents a new method for quantifying c (dynamic approach) that is consistent with the observed DO concentration fluctuations near the interface. Data were used from a series of flume experiments that includes both physical and kinetic uptake limitations of the flux. Results indicated that methods for quantifying k and c using the surface renewal theory better estimated the DO flux across a range of fluid-flow conditions.

In order to reach grid parity, however, costs must be reduced substantially. Inexpensive materials generally exhibit efficiencies too low for practical application, but by controlling the morphology on the nanoscale there are opportunities to achieve significant improvements in this area. Block copolymers, which naturally self-assemble into periodic ordered nanostructures, can be utilized in diverse ways to control morphology, ranging from active layers to structure directors to a combination of these methodologies.

The mannitol-specific PTS catalyze the uptake and phosphorylation of d-mannitol. The uptake system comprises several genes encoded in the single operon. The expression of the mannitol operon is regulated by a proposed transcriptional factor, mannitol operon repressor (MtlR) that was first studied in Escherichia coli. Here we report the first crystal structures of MtlR from Vibrio parahemeolyticus (Vp-MtlR) and its homolog YggD protein from Shigella flexneri (Sf-YggD). MtlR and YggD belong to the same protein family (Pfam05068). Although Vp-MtlR and Sf-YggD share low sequence identity (22%), their overall structures are very similar, representing a novel all a-helical fold, and indicate similar function. However, their lack of any known DNA-binding structural motifs and their unfavorable electrostatic properties imply that MtlR/YggD are unlikely to bind a specific DNA operator directly as proposed earlier. This structural observation is further corroborated by in vitro DNA-binding studies of E. coli MtlR (Ec-MtlR), which detected no interaction of Ec-MtlR with the well characterized mannitol operator/promoter region. Therefore, MtlR/YggD belongs to a new class of transcription factors in bacteria that may regulate gene expression indirectly as a part of a larger transcriptional complex.

It was assumed that an RDD event would result in outside surface contamination of the exterior walls and roofs of surrounding buildings, as well as associated paved areas and lawns. The contaminants also might move inside the buildings and deposit on floors and interior walls. Some important input parameters include occupancy factors, building characteristics, and weathering of surface contamination. The modeling results include predicted external dose rates, relative contributions from important surfaces, annual and cumulative doses, and radionuclide concentrations. Potential countermeasures evaluated include grass removal, soil removal, and washing of paved areas.

Journal of the American Water Resources Association (JAWRA) 45(6):1379-1389. Abstract: Arctic communities are increasingly faced with social-ecological changes that act at variable speeds and spatial scales. Such changes will affect vital resources, particularly water supplies. Currently, there are few computational tools that integrate multiple social and environmental processes in order to aid communities' adaptation to change through decision support systems. This paper proposes a modeling and simulation approach that can integrate such processes at different spatiotemporal scales in order to address issues affecting community water supplies. In this paper, a modeling and simulation tool is developed and applied to a case study on the Seward Peninsula. Initial results, using both field observations and computation, show projected patterns of water use, perceptions of water availability, and long-term consumption trends. More broadly, the paper demonstrates the need for developing tools that address issues at the community level for better understanding human and hydrological interactions and policy decisions affecting water supplies.

12529442 AB - Even before the United States' entry-into-force of the Additional Protocol (AP) in January 2009, the United States has been promoting universal adherence to the AP to strengthen both nuclear safeguards and broader nuclear nonproliferation objectives. This commitment was exemplified in the U.S. AP Implementation Act and Senate Resolution of Ratification, which require the Administration to report annually to Congress on measures taken to achieve the adoption of the AP in non-nuclear weapon states (NNWSs), as well to report assistance provided to the International Atomic Energy Agency (IAEA) for the effective implementation of APs in those states. Under the International Nuclear Safeguards and Engagement Program (INSEP) of the U.S. Department of Energy/National Nuclear Security Administration (DOE/NNSA), bilateral cooperation arrangements have been initiated with selected NNWSs to help meet the U.S. goals related to universal adherence to the AP. The INSEP's international AP implementation program collaborates with technical experts in partner countries to understand AP implementation issues and to develop a methodology and system to implement the AP. The engagement program is expected to assist countries in signing the AP, bringing it into force, and effectively implement the AP, depending on where that country is in the process.

14133218 AB - The decline of many snake populations is attributable to habitat loss, and knowledge of habitat use is critical to their conservation. Resource characteristics (e.g., relative availability of different habitat types, soils, and slopes) within a landscape are scale-dependent and may not be equal across multiple spatial scales. Thus, it is important to identify the relevant spatial scales at which resource selection occurs. We conducted a radiotelemetry study of eastern hognose snake (Heterodon platirhinos) home range size and resource use at different hierarchical spatial scales. We present the results for 8 snakes radiotracked during a 2-year study at New Boston Air Force Station (NBAFS) in southern New Hampshire, USA, where the species is listed by the state as endangered. Mean home range size (minimum convex polygon) at NBAFS (51.7 plus or minus 14.7 ha) was similar to that reported in other parts of the species' range. Radiotracked snakes exhibited different patterns of resource use at different spatial scales. At the landscape scale (selection of locations within the landscape), snakes overutilized old-field and forest edge habitats and underutilized forested habitats and wetlands relative to availability. At this scale, snakes also overutilized areas containing sandy loam soils and areas with lower slope (mean slope = 5.2% at snake locations vs. 6.7% at random locations). We failed to detect some of these patterns of resource use at the home range scale (i.e., within the home range). Our ability to detect resource selection by the snakes only at the landscape scale is likely the result of greater heterogeneity in macrohabitat features at the broader landscape scale. From a management perspective, future studies of habitat selection for rare species should include measurement of available habitat at spatial scales larger than the home range. We suggest that the maintenance of open early successional habitats as a component of forested landscapes will be critical for the persistence of eastern hognose snake populations in the northeastern United States.

For samples with anoxic pretreatment, the contribution of reduced inorganic S compounds (monosulfide, pyrite) to total S increased with soil depth for the Cambisol and the Stagnosol, but decreased for the Histosols; the opposite trend was noticed for the contribution of reduced organic S (organic mono- and disulfides, thiols). The contribution of reduced S to the soil S pool increased and the contribution of oxidized S compounds decreased in the sequence Cambisol-Stagnosol-Histosol 1 (permanently anoxic). Histosol 2 (seasonally oxic) showed a markedly larger contribution of oxidized and intermediate S compounds to total S than Histosol 1. The dominating Fe-bearing phases in the Cambisol were Fe(III) oxyhydroxides; the contribution of sulfide-bound Fe was <5% of total Fe in all horizons. In Histosol 1, the contribution of sulfide-bound Fe increased with soil depth up to 50% in the Cr horizon, whereas in Histosol 2 Fe(III) phases strongly dominated in all horizons. After conventional oxic sample pretreatment, the contribution of reduced inorganic S to total S was markedly decreased in all soils. In the organic surface horizons, the contribution of reduced organic S was increased to the same extent; the contribution of oxidized S (sulfate) remained more or less unchanged. In the mineral soil, the contribution of sulfate and the mean oxidation state of sulfur (MOS) were strongly increased after oxic sample preparation. In Histosol 1, oxic sample pretreatment resulted in oxidation of labile Fe(II) compounds, probably sulfides or Fe(II)-S-org-complexes, to Fe(III). Our study shows that for anoxic wetland soils which contain inorganic sulfide and/or divalent Fe, the exclusion of O (sub 2) during the entire period between sampling and analysis is crucial for a correct S and Fe speciation. Only after appropriate sample preparation, clear relationships between the mean oxidation states of S and Fe (MOFe) on one hand and soil hydrological conditions on the other become evident: a concomitant systematic decrease of MOS and MOFe from the well-aerated Cambisol to the permanently anoxic Histosol 1, and larger MOS and MOFe in the seasonally oxic Histosol 2 than in Histosol 1 indicate a close coupling of S and Fe cycling in the soils. Finally, the results of our study suggest that in organic horizons of wetland soils inorganic sulfide S is overestimated and reduced organic S is underestimated by S K-edge XANES, if a significant portion of the thiol groups in reduced organic S is complex-bound to Fe (super 2+) or other chalcophilic metal cations. This is supported by the observation that synthetic organic compounds (cysteine; 1,3,5-trimer-captotriazine [TMT]; ferredoxin) after addition of Fe show spectra with pre-edge peaks at energies <2472 eV that are typical for inorganic sulfide.

The Ne ions were implanted sequentially at two different energies to create a more uniform depth distribution. The targets were stable under high beam loads. To reduce the amount of oxygen contamination on the target's surface, a procedure of chemical cleaning and thermal outgassing of targets was developed. The impact of this treatment on implanted Ne targets was investigated and found to reduce the oxygen amount by a factor of 4. The depth profile of the implanted Ne atoms was studied via narrow (p,g) resonances while the oxygen contamination was monitored using the Deuteron-Induced g-ray Emission (DIGE) method.

Our analysis revealed that the amount of irrigation water used to grow biofuel feedstocks varies significantly from one region to another and that water consumption for biofuel production varies with processing technology. In oil exploration and production, water consumption depends on the source and location of crude, the recovery technology, and the amount of produced water re-injected for oil recovery. Our results also indicate that crop irrigation is the most important factor determining water consumption in the production of corn ethanol. Nearly 70% of U.S. corn used for ethanol is produced in regions where 10-17 liters of water are consumed to produce one liter of ethanol. Ethanol production plants are less water intensive and there is a downward trend in water consumption. Water requirements for switchgrass ethanol production vary from 1.9 to 9.8 liters for each liter of ethanol produced. We found that water is consumed at a rate of 2.8-6.6 liters for each liter of gasoline produced for more than 90% of crude oil obtained from conventional onshore sources in the U.S. and more than half of crude oil imported from Saudi Arabia. For more than 55% of crude oil from Canadian oil sands, about 5.2 liters of water are consumed for each liter of gasoline produced. Our analysis highlighted the vital importance of water management during the feedstock production and conversion stage of the fuel lifecycle.

Radiography allows quantitative measurements of the fuel distribution in sprays to be made with high temporal and spatial resolution. Measurements have been made at different values of injection pressure, ambient density, and with two different nozzle geometries to understand the influences of these parameters on the spray structure of the biodiesel blend. These measurements have been compared with corresponding measurements of Viscor, a diesel calibration fluid, to demonstrate the fuel effects on the spray structure. Generally, the biodiesel-blend spray has a similar structure to the spray of Viscor. For the nonhydroground nozzle used in this study, the biodiesel-blend spray has a slightly slower penetration into the ambient gas than the Viscor spray. The cone angle of the biodiesel-blend spray is generally smaller than that of the Viscor spray, indicating that the biodiesel-blend spray is denser than the Viscor spray. For the hydroground nozzle, both fuels produce sprays with initially wide cone angles that transition to narrow sprays during the steady-state portion of the injection event. These variations in cone angle with time occur later for the biodiesel-blend spray than for the Viscor spray, indicating that the dynamics of the injector needle as it opens are somewhat different for the two fuels.

13268274 AB - The Pearl River Delta region (PRD) of China has long suffered from severe ground-level ozone pollution. Knowledge of the sources of volatile organic compounds (VOCs) is essential for ozone chemistry. In this work, a speciated VOC emission inventory was established on the basis of updated emissions and local VOC source profiles. The top 10 species, in terms of ozone formation potentials (OFPs), consisted of isoprene, mp-xylene, toluene, ethylene, propene, o-xylene, 1,2,4-trimethylbenzene, 2-methyl-2-butene, 1-butene, and *a-pinene. These species contributed only 35.9% to VOCs emissions but accounted for 64.1% of the OFP in the region. The spatial patterns of the VOC source inventory agreed well with city-based source apportionment results, especially for vehicle emissions and industry plus VOC product-related emissions. Mapping of the OFPs and measured ozone concentrations indicated that the formation of higher ozone in the south and southeast of the PRD region differed from that in the Conghua area, a remote area in the north of the PRD. We recommend that the priorities for the control of VOC sources include motorcycles, gasoline vehicles, and solvent use because of their larger OFP contributions.

Here we report that the biomineralization of Au nanoparticles in the metallophillic bacterium Cupriavidus metallidurans CH34 is the result of Au-regulated gene expression leading to the energy-dependent reductive precipitation of toxic Au(III)-complexes. C. metallidurans, which forms biofilms on Au grains, rapidly accumulates Au(III)-complexes from solution. Bulk and microbeam synchrotron X-ray analyses revealed that cellular Au accumulation is coupled to the formation of Au(I)-S complexes. This process promotes Au toxicity and C. metallidurans reacts by inducing oxidative stress and metal resistances gene clusters (including a Au-specific operon) to promote cellular defense. As a result, Au detoxification is mediated by a combination of efflux, reduction, and possibly methylation of Au-complexes, leading to the formation of Au(I)-C-compounds and nanoparticulate Au (super 0) . Similar particles were observed in bacterial biofilms on Au grains, suggesting that bacteria actively contribute to the formation of Au grains in surface environments. The recognition of specific genetic responses to Au opens the way for the development of bioexploration and bioprocessing tools.

13268265 AB - Samples of a naturally bioreduced, U-contaminated alluvial sediment were characterized with various microscopic and spectroscopic techniques and wet chemical extraction methods. The objective was to investigate U association and interaction with minerals of the sediment. Bioreduced sediment comprises 10% of an alluvial aquifer adjacent to the Colorado River, in Rifle, CO, that was the site of a former U milling operation. Past and ongoing research has demonstrated that bioreduced sediment is elevated in solid-associated U, total organic carbon, and acid-volatile sulfide, and depleted in bioavailable Fe(III) confirming that sulfate and Fe(III) reduction have occurred naturally in the sediment. SEM/EDS analyses demonstrated that framboidal pyrites (FeS2) of different sizes (10-20 *mm in diameter), and of various microcrystal morphology, degree of surface weathering, and internal porosity were abundant in the <53 *mm fraction (silt + clay) of the sediment and absent in adjacent sediments that were not bioreduced. SEM-EMPA, XRF, EXAFS, and XANES measurements showed elevated U was present in framboidal pyrite as both U(VI) and U(IV). This result indicates that U may be sequestered in situ under conditions of microbially driven sulfate reduction and pyrite formation. Conversely, such pyrites in alluvial sediments provide a long-term source of U under conditions of slow oxidation, contributing to the persistence of U of some U plumes.

It is believed that the Nubian Aquifer in the WD, ED, and SP was recharged in the previous wet climatic periods. While this statement is true for the WD, it is not for the ED and Sinai. In dry climatic periods similar to the ones we are witnessing today, the Nubian Sandstone (NSS) Aquifer in the Western Desert of Egypt is receiving no local recharge because negligible rain is precipitating. That is not apparently the case in the ED and more so in the Sinai Peninsula. In both areas, precipitation over the mountains is channeled downstream over the NSS cropping out at the foothills of the Red Sea hills providing ample opportunities for groundwater recharge. The conceptual model outlined above has been successfully tested in the SP using geophysical, isotopic, and rainfall-runoff modeling. Interpretations of conventional Electrical Resistivity (ER) profiles is consistent with the presence of unconfined Nubian Sandstone saturated aquifers flooring recharge areas at the foothills of the crystalline basement in Sinai at the Baraga (thickness: 65-100m; resistivity: 100-125 ohm.m) and Zalaga (thickness: 20-166.7-m; resistivity: 25-130 ohm.m) locations. The isotopic composition of groundwater samples from wells tapping Nubian aquifer underlying recharge areas (delta D: -22.7 to -32.8ppm) is consistent with these waters being mixtures of two end members: (1) fossil Nubian groundwater with compositions similar to the WD Nubian samples (delta D -72 to -81ppm) and, (2) modern meteoric precipitation (delta D -19.9 to -22.5ppm) now residing in fractured basement in the SP. The average annual modern recharge over the Nubian Aquifer was assessed at 3.2 X 10 (super 5) m (super 3) /yr applying the SWAT (Soil Water Assessment Tool) Hydrologic Model.

The nonracemic amino acids of meteorites provide the only reported natural example of molecular asymmetry measured outside of the biosphere. Did life inherit such asymmetry from these and other prebiotic molecules of extraterrestrial origin? This presentation will describe laboratory gas gun experiments conducted to test whether amino acids preserve their chirality through the extreme temperature and pressure changes associated with shock processing. A mixture of amino acids, including racemic enantiomers and single enantiomer species, was dissolved in water. Aliquots of this solution were sealed inside stainless steel capsules and subjected to a planar impact by copper projectiles traveling at velocities of 1-1.2 km/s. These velocities, which represent a near-upper limit for our gas gun assembly, correspond to the vertical component of a low angle, terrestrial impact. Pressures generated from shock waves traveling through the capsules were calculated based on impedence matching; temperature histories were calculated using equations of state data for water. Solutions were characterized by liquid chromatography and mass spectrometry before and after an experiment. While the liquids recovered from the shocked capsules exhibited chemical change with respect to their relative abundance of amino acids, all of the initial amino acid species were still present. We determined that the initial chirality of our amino acids was preserved.

In particular, the reduction of Fe(III) is one of the most important chemical changes that takes place in the development of anaerobic soils and sediments, and the reductive dissolution of iron-bearing minerals by microbes plays a critical role in this process. Despite its importance in biogeochemistry, many questions remain about the mechanism of this electron transfer reaction, in part because the speed of the fundamental chemical steps renders them inaccessible to conventional study. Ultrafast time-resolved x-ray spectroscopy is a technique that can overcome this limitation and measure changes in oxidation state and structure occurring during chemical reactions that can be initiated by a fast laser pulse. We use this approach with approximately 100 ps resolution to monitor the speciation of Fe atoms in maghemite nanoparticles following photo-induced electron transfer from a surface-bound photoactive dye molecule. Magnetite nanoparticles, synthesized by co-precipitation of Fe(II) and Fe(III) in basic aqueous solution, were oxidized by O (sub 2) to give maghemite particles 2-3 nm in diameter (by XRD). UV/vis absorption and fluorescence spectroscopy showed that the dye, 2,7-dichlorofluorescein, binds strongly to the particle surface and that its emission is quenched fully when bound. Under steady-state photoexcitation, dye-sensitized particles evolved Fe (super 2+) (aq) over time, indicating successful electron transfer from sensitizer to particle, followed by reductive dissolution. Pump-probe X-ray absorption spectroscopy measurements at the Fe K edge, using a free jet of a deoxygenated aqueous suspension of dye-sensitized maghemite, showed the transient formation of a reduced iron species following laser excitation. No transient species were observed in control experiments using unsensitized nanoparticles. These data represent the first direct real-time observation of the dynamics of ferrous ion formation and subsequent re-oxidation or dissolution in iron oxide.

This study investigated abiotic and biological degradation of RDX within contaminated aquifer sediment. Batch incubations of contaminated aquifer material were performed with and without pre-aeration to distinguish biological RDX reduction from abiotic RDX reduction. Acetate or lactate was added as an electron donor to promote the biological reduction of RDX. Without pre-aeration of the sediment, RDX was reduced by coupled abiotic and biological processes. Abiotic RDX reduction in the sediment was attributed to chemical reductants in the native aquifer sediment, primarily Fe(II) associated with mineral surfaces. To assess biological process alone, chemical reductants in the native sediment were removed by pre-aeration. RDX (50mu M) was completely reduced and transformed to ring cleavage products when 2mM of acetate or lactate as the electron donor were provided. Biomass increased 3 and 1.6 times in the presence of acetate and lactate, respectively, suggesting that electron donors added to contaminated aquifer sediments can stimulate RDX biotransformation. RDX reduction occurred concurrently with iron reduction when acetate was provided, while both iron and sulfate reduction were dominant when lactate was provided. This indicates that acetate and lactate promote the development of different types of microbial communities and different terminal electron accepting processes, which in turn control the dynamics of RDX transformation. Although significant amounts of iron and/or sulfate were reduced, reactive minerals (i.e., magnetite, green rust, and sulfide minerals) were not observed, suggesting RDX reduction in the aquifer sediment is likely due to surface associated Fe(II). These results suggest that both biotic and abiotic processes can play an important role in RDX reduction under in situ conditions. Investigation of the dominant microorganisms associated with RDX, Fe(III), and/or sulfate reduction using total microbial community analysis (i.e., clone library construction and high-throughput sequencing) is ongoing.

Here we report the effects of Fe (super 3+) and Al (super 3+) on Mg-silicate perovskite at high pressure. Perovskites with 0.09Fe (sub 2) O (sub 3) . 0.91MgSiO (sub 3) and 0.05Fe (sub 2) O (sub 3) . 0.05Al (sub 2) O (sub 3) . 0.9MgSiO (sub 3) were synthesized above 50 GPa in the laser-heated diamond-cell. The spin state of Fe (super 3+) was determined by synchrotron Mossbauer spectroscopy and X-ray emission spectroscopy at high-pressure. The effect of trivalent cation substitution on the unit cell volume of perovskite was investigated using synchrotron X-ray diffraction. Above 50 GPa, Fe (super 3+) and Al (super 3+) enter the perovskite structure primarily by charge-coupled substitution. When Fe (super 3+) exists alone in perovskite, it enters both the dodecahedral and octahedral sites. With compression, Fe (super 3+) in the octahedral site undergoes a gradual change to the low spin state, while Fe (super 3+) in the dodecahedral site remains high spin to at least 136 GPa. The spin transition results in a low bulk modulus for perovskite below 60 GPa. When Fe3+ exists together with Al, at low pressure the majority of Fe (super 3+) sits in the dodecahedral site in the high spin state. However, we found a rapid increase in the low spin Fe (super 3+) fraction in the octahedral site of perovskite at approximately 70 GPa. Because low spin Fe (super 3+) is similar in size to Al (super 3+) , more Fe (super 3+) enters the octahedral site at higher pressure, while Al (super 3+) must enter into the dodecahedral site. Above 80 GPa, approximately half of the Fe (super 3+) exists in the octahedral site. As a result of the site mixing, the Al-bearing perovskite has a significantly smaller volume at lowermost mantle pressures.

X-ray reflection interface microscopy (XRIM), a capability established recently at the Advanced Photon Source, is a powerful new tool for interfacial studies. XRIM probes interfaces through the reflection of a focused X-ray microbeam, and therefore has all of the sensitivities of X-ray reflectivity (XR) including interfacial structure and composition. The use of an X-ray objective lens enables the lateral variation of the X-ray reflectivity signal to be spatially resolved, thereby yielding images of lateral topography and structure with direct sensitivity to sub-nm vertical features (e.g., unit-cell height steps). The first results on the application of XRIM to probing interfacial reactivity will be described, in which we observe dissolution of the orthoclase (001) surface at alkaline pH. Specifically, ex-situ XRIM images, combined with in-situ time-resolved XR measurements reveal changes in the dissolution rate and dissolution process due to the addition of NaCl. Recent results on the extending this capability to imaging in-situ processes will be described, including both the challenges and the unique opportunities.

Our work in recent years has sought to provide new insight into metal oxide-water interfaces in two areas: the ordering of water and the mechanisms of oxoanion adsorption at these interfaces. We have explored the structure of interfacial water on a number of hematite (alpha -Fe (sub 2) O (sub 3) ) and corundum (alpha -Al (sub 2) O (sub 3) ) surfaces. While ordering in this water appears to be a general phenomenon, with the degree of ordering declining away from the surface on the length scale of approximately 1-2 nanometers, quantitative differences in water structure and positional disorder exist among the different surfaces examined. We have also recently investigated arsenate (AsO (sub 4) (super 3-) ) adsorption on the (012) surfaces of these minerals and have demonstrated that the accepted conceptual model for this process has been missing a key mechanism: outer-sphere adsorption. We observed that arsenate simultaneously forms inner- and outer-sphere surface complexes at pH 5 and 0.01 M ionic strength on both oxides. We have begun to investigate the dependence of this unexpectedly complex adsorption behavior on pH, ionic strength, and the crystallographic orientation of the sorbent mineral phase. These studies explore how variations in chemical conditions and interfacial water ordering affect arsenate adsorption behavior. Our observations suggest a connection between the molecular-scale arrangement of water near a mineral surface and the chemical properties of that surface.

Despite their tamper-indicating features, all of these products can be quickly and easily tampered with, either before or after sample collection, while leaving little or (usually) no evidence to be detected. Either false-positive or false-negative drug test results could then occur. A brief review of other security practices and standards associated with urine drug testing suggests there may often be additional serious security problems. Given the importance of drug testing and the fact that illicit drug tests have a huge impact on people's careers, livelihoods, and reputations, better security, especially better tamper detection features, would seem warranted.

At relatively low applied stresses and at low temperatures, the presence of methane in helium reduced the rupture strain significantly while increasing the rupture life relative to the behavior in pure helium. The degradation in rupture strain is due to the occurrence of cleavage fracture in the He + CH sub(4) environment; this explanation is also supported by high activation energy (Q = 723 kJ/mol) for creep in He + CH sub(4). At higher applied stresses and also at higher temperatures, creep-rupture behavior in He and He + CH sub(4) was similar. Creep response in pure He and in CO-CO sub(2) follows a dislocation climb-controlled power-law behavior whereas that in He + CH sub(4) has a different behavior as indicated by the high stress exponent (n = 9.8). The activation energy for creep in pure He was 391 kJ/mol and in CO-CO sub(2) was 398 kJ/mol, and appeared to be independent of stress in both environments. On the other hand, in He + CH sub(4), the activation energy (Q = 723 kJ/mol) seems to be dependent on stress.

There is no optimum method of establishing the stringency of a standard, but policymakers can be informed by analyses of technology cost-effectiveness from the viewpoint of different actors (e.g., society, vehicle purchasers) and of "top runners" - vehicles in the current fleet, or projections of future leading vehicles, that can serve as models for average vehicles some years later. The focus of the paper is on the US light vehicle fleet, with some discussion of applications to the European Union. A "leading edge" midsize car for the 2020 timeframe is identified, and various types of attribute-based standards are discussed. For the US, a 12-15 year target for new vehicle fleet improvement of 30-50% seems a reasonable starting point for negotiations. For 2030 or so, doubling current fuel economy is possible. In both cases, adjustments must be made in response to changing economic circumstances and government and societal priorities.

11072632 AB - Oxidation experiments were conducted at 1000-1200 not equal to in flowing steam with samples of as-received Zr-1Nb alloy E110 tubing and/or polished E110 tubing. The purpose was to determine the oxidation behavior of this alloy under postulated loss-of-coolant accident conditions in light water reactors. The as-received E110 tubing exhibited a high degree of susceptibility to nodular oxidation and breakaway oxidation at relatively low test times, as compared to other cladding alloys. The nodules grew much more rapidly at 1000 not equal to than 1100 not equal to , as did the associated hydrogen uptake. The oxidation behavior was strongly affected by the surface condition of the materials. Polishing to [asymptotic to]0.1 mu m roughness (the roughness of the as-received tubing was [asymptotic to]0.4 mu m) delayed breakaway oxidation. Polishing also removed surface impurities. For polished samples oxidized at 1100 not equal to , no significant nodular oxidation appeared up to 1000 s. For polished samples oxidized at 1000 not equal to , hydrogen uptake >100 wppm was delayed from [asymptotic to]300 s to >900 s. Weight-gain coefficients were determined for pre-breakaway oxidation of polished-only and machined-and-polished E110 tubing samples: 0.162 (mg/cm super(2))/s super(0.5) at 1000 not equal to and 0.613 (mg/cm super(2))/s super(0.5) at 1100 not equal to .

Nanoporous systems engineered to mimic natural filtration systems are actively being developed for use in smart implantable drug delivery systems, bioartificial organs, and other novel nano-enabled medical devices. Recent advances in nanoscience have made it possible to precisely control the morphology as well as physical and chemical properties of the pores in nanoporous materials that make them increasingly attractive for regulating and sensing transport at the molecular level. In this work, an overview of nanoporous membranes for biomedical applications is given. Various in vivo and in vitro membrane applications, including biosensing, biosorting, immunoisolation, and drug delivery, are presented. Different types of nanoporous materials and their fabrication techniques are discussed with an emphasis on membranes with ordered pores. Desirable properties of membranes used in implantable devices, including biocompatibility and antibiofouling behavior, are discussed. The use of surface modification techniques to improve the function of nanoporous membranes is reviewed. Despite the extensive research carried out in fabrication, characterization, and modeling of nanoporous materials, there are still several challenges that must be overcome in order to create synthetic nanoporous systems that behave similarly to their biological counterparts.

The enzyme CapD generates amide bonds with peptidoglycan cross-bridges to anchor capsular material within the cell wall envelope of B. anthracis. The capsular biosynthetic pathway is essential for virulence during anthrax infections and can be targeted for anti-infective inhibition with small molecules. Here, we present the crystal structures of the g-glutamyltranspeptidase CapD with and without a-l-Glu-l-Glu dipeptide, a non-hydrolyzable analog of poly-g-d-glutamic acid, in the active site. Purified CapD displays transpeptidation activity in vitro, and its structure reveals an active site broadly accessible for poly-g-glutamate binding and processing. Using structural and biochemical information, we derive a mechanistic model for CapD catalysis whereby Pro super(427), Gly super(428), and Gly super(429) activate the catalytic residue of the enzyme, Thr super(352), and stabilize an oxyanion hole via main chain amide hydrogen bonds.

13268048 AB - This research evaluated a method of controlled base addition for immobilizing uranium (U) and technetium (Tc) through co-precipitation with aluminum (Al) and other metal ions which co-exist in a highly contaminated acidic environment. The batch and column experiments indicate that the addition of strong base (NaOH) provided a rapid yet effective means of sequestering U, Tc, and toxic metal ions such as nickel (Ni2+) and cobalt (Co super(2+)) in the sediment and groundwater. Greater than 94% of soluble U (as UO sub(2) super(2+)) and >83% of Tc (as TcO super(4-)) can be immobilized at pH above 4.5 by co-precipitation with Al-oxyhydroxides. The presence of sediment minerals appeared to facilitate co-precipitation of these contaminants at lower pH values than those in the absence of sediments. The immobilized U and Tc were found to be stable against dissolution in Ca(NO sub(3)) sub(2) solution (up to 50 mM) because of the formation of strong surface complexes between U or Tc and Al-oxyhydroxides. This research concludes that, as long as a relatively high pH (>5) and a low carbonate concentration are maintained, both U and Tc can be effectively immobilized under given site-specific conditions.

We infer these grains crystallized from shock-generated melt over a time interval of <1 mu s, the maximum time over which our experiment reached and sustained pressure sufficient to stabilize this phase. This rapid crystal growth rate ( nearly equal 1 m/s) suggests that, contrary to the conclusions of previous studies of the occurrence of high-pressure phases in shock-melt veins in strongly shocked meteorites, the growth of high-pressure phases from the melt during shock events is not diffusion-controlled. Another process, such as microturbulent transport, must be active in the crystal growth process. This result implies that the times necessary to crystallize the high-pressure phases in shocked meteorites may correspond to shock pressure durations achieved on impacts between objects 1-5 m in diameter and not, as previously inferred, nearly equal 1-5 km in diameter. These results may also provide another pathway for syntheses, via shock recovery, of some high-value, high-pressure phases.

The second heat treatment simulated the manufacturing cycle for large components, and is directly relevant for the ITER divertor components. Specimens were neutron irradiated at [not, vert, similar]80 C to two fluences, 2 x 10 super(24) and 2 x 10 super(25) n/m super(2) (E > 0.1 MeV), corresponding to displacement doses of 0.15 and 1.5 displacements per atom (dpa). Tensile and fracture toughness tests were carried out at room temperature. Significant irradiation hardening and plastic instability at yield occurred in both heat treatment conditions with a saturation dose of [not, vert, similar]0.1 dpa. Neutron irradiation slightly reduced fracture toughness in CuCrZr SAA and CuCrZr SCA. The fracture toughness of CuCrZr remained high up to 1.5 dpa (J sub(Q )> 200 kJ/m super(2)) for both heat treatment conditions.

AN - 67631297; 19725673 AB - We present a nuclear radiation detection mechanism using millimeter waves as an alternative to conventional detection. It is based on the concept that nuclear radiation causes ionization of air and that if we place a dielectric material near the radiation source, it acts as a charge accumulator of the air ions. We have found that millimeter waves can interrogate the charge cloud on the dielectric material remotely. This concept was tested with a standoff millimeter wave system by monitoring the charge levels on a cardboard tube placed in an x-ray beam.

The experiments were conducted as a function of pH and demonstrate that the complex mixtures of bacteria, containing both Gram-positive and Gram-negative species, yield relatively simple EXAFS spectra, a result which indicates that only a limited number of functional group types contribute to Cd binding for each bacterial consortium. The EXAFS spectra indicate that the average Cd binding environment in the river water consortium varies significantly with pH, but the manufacturing gas plant consortium exhibits a Cd binding environment that remains relatively constant over the pH range examined. The EXAFS data for the river water consortium were modeled using carboxyl, phosphoryl and sulfhydryl sites. However, only carboxyl and phosphoryl sites were required to model the manufacturing gas plant consortium data under similar experimental conditions. This is the first EXAFS study to identify and quantify the relative importance of metal binding sites in bacterial consortia. Although our results indicate differences in the binding environments of the two consortia, the data suggest that there are broad similarities in the binding environments present on a wide range of bacterial cell walls.

Single-phase computational fluid dynamics (CFD) analyses fail to account for particulate migration. Consequently, inconsistencies arise when correlating adhesion with wall shear stress (WSS). The purpose of this paper is to present, to our knowledge, the first computational analysis of in vitro U937 monocyte-like human cell adhesion data using a coupled multiphase CFD-population balance adhesion model. The CFD model incorporates multiphase non-Newtonian hemodynamic models to compute the spatial distributions of freely flowing monocytes and WSSs in control volumes adjacent to the wall. Measurements of monocyte adhesion onto an E-selectin-coated flow model that included an idealized stenosis and an abrupt expansion were available from the literature. In this study, we develop a new monolayer population balance adhesion model, based on the widely accepted mechanism of ligand-receptor binding, coupled to the CFD results. The monolayer population balance model accounts for the interactions of freely flowing, rolling, and adhering monocytes with surfaces via first-order reactions, transport of rolling cells in the monolayer, and the concept of a WSS detachment threshold, clearly evident in the adhesion experiments. The new paradigm of coupling the multiphase hemodynamic CFD model with the proposed adhesion model is illustrated by determining and interpreting the model parameters for experimental datasets having Reynolds numbers of 100 and 140. The coupled multiphase CFD adhesion model is able to simultaneously predict the spatial variations in freely flowing monocytes, their adherent number density, and carrier fluid WSSs adjacent to ligand-coated flow cell surfaces.

Studies in experimental animals have addressed whether very low concentrations of dietary cadmium can negatively impact the skeleton. This overview evaluates results in experimental animals regarding mechanisms of action on bone and the application of these results to humans. Results demonstrate that long-term dietary exposures in rats, at levels corresponding to environmental exposures in humans, result in increased skeletal fragility and decreased mineral density. Cadmium-induced demineralization begins soon after exposure, within 24 h of an oral dose to mice. In bone culture systems, cadmium at low concentrations acts directly on bone cells to cause both decreases in bone formation and increases in bone resorption, independent of its effects on kidney, intestine, or circulating hormone concentrations. Results from gene expression microarray and gene knock-out mouse models provide insight into mechanisms by which cadmium may affect bone. Application of the results to humans is considered with respect to cigarette smoke exposure pathways and direct vs. indirect effects of cadmium. Clearly, understanding the mechanism(s) by which cadmium causes bone loss in experimental animals will provide insight into its diverse effects in humans. Preventing bone loss is critical to maintaining an active, independent lifestyle, particularly among elderly persons. Identifying environmental factors such as cadmium that contribute to increased fractures in humans is an important undertaking and a first step to prevention.

We show that the newly added NO sub(x) emissions from new power plants in Inner Mongolia, China, were detected by the Ozone Monitoring Instrument (OMI) aboard NASA's Aura satellite. Increase rates of NO sub(2) columns from OMI and NO sub(x) emissions from inventories are even in quantitative agreement in cases where new facilities are added to already-developed regions. This study confirms that the OMI products are quite capable of identifying the construction of large new emitting facilities through detection of their NO sub(x) emissions.

AN - 67612765; 19708356 AB - Evidence is increasing for the mobility and bioavailability of aqueous mercury(II) species being related to the interactions of mercury with dissolved organic matter (DOM). Here, we assess the relative roles of the mineral surface and DOM in controlling mercury(II) uptake at the muscovite (001)-solution interface using interface-specific X-ray reflectivity combined with element-specific resonant anomalous X-ray reflectivity. Experiments were performed with single crystals of muscovite and solutions of 100 mg/kg Elliott Soil Fulvic Acid II and 0.5-1 x 10(-3) mol/kg Hg(NO3)2 at pH 2-12 Mercury(II) adsorbed from a 1 x 10(-3) mol/kg Hg(II) solution at pH 2 without fulvic acid (FA) as inner- and outer-sphere complexes that compensated 55(4)% of the permanent negative charge of the muscovite surface. The remaining charge presumably was compensated by hydronium. The enhanced uptake of Hg(II) (compensating 128% of the muscovite surface charge) and FA (43% more adsorbed compared to the amount from a similar solution without Hg), along with a broader distribution of Hg(II) at the interface, occurred by adsorption from a premixed solution of 1 x 10(-3) mol/kg Hg(NO3)2 and 100 mg/kg FA at pH 2. Adsorption of Hg(II) and FA, likely as complexes, decreased significantly as pH increased from 3.7 to 12 in solutions of 0.5 x 10(-3) mol/kg Hg(NO3)2 and 100 mg/kg FA. Preadsorbed FA molecules provide different binding environments and stability for Hg(II) than dissolved FA, which may be attributed to conformational differences, fractionation, or kinetic effects in the presence of the mineral surface, at least at these relatively high concentrations of aqueous Hg(II).

13267727 AB - Aerosol distributions in Asia calculated over a 4-year period and constrained by satellite observations of aerosol optical depth (AOD) are presented. Vast regions in Asia that include >80% of the population have PM2.5 concentrations that exceed on an annual basis the WHO guideline of 10 *mg/m3, often by factors of 2 to 4. These high aerosol loadings also have important radiative effects, causing a significant dimming at the surface, and mask 45% of the warming by greenhouse gases. Black carbon (BC) concentrations are high throughout Asia, representing 5-10% of the total AOD, and contributing significantly to atmospheric warming (its warming potential is 55% of that due to CO2). PM levels and AODs in year 2030, estimated based on simulations that consider future changes in emissions, are used to explore opportunities for win-win strategies built upon addressing air quality and climate change together. It is found that in 2030 the PM2.5 levels in significant parts of Asia will increase and exacerbate health impacts; but the aerosols will have a larger masking effect on radiative forcing, due to a decrease in BC and an increase in SO2 emissions.

Sustainability will be a strong factor in the regulatory environment and investments in biofuels. Biomass feedstock production is an important contributor to environmental, social, and economic impacts from biofuels. This study presents a systems approach where the agricultural, energy, and environmental sectors are considered as components of a single system, and environmental liabilities are used as recoverable resources for biomass feedstock production. We focus on efficient use of land and water resources. We conducted a spatial analysis evaluating marginal land and degraded water resources to improve feedstock productivity with concomitant environmental restoration for the state of Nebraska. Results indicate that utilizing marginal land resources such as riparian and roadway buffer strips, brownfield sites, and marginal agricultural land could produce enough feedstocks to meet a maximum of 22% of the energy requirements of the state compared to the current supply of 2%. Degraded water resources such as nitrate-contaminated groundwater and wastewater were evaluated as sources of nutrients and water to improve feedstock productivity. Spatial overlap between degraded water and marginal land resources was found to be as high as 96% and could maintain sustainable feedstock production on marginal lands. Other benefits of implementing this strategy include feedstock intensification to decrease biomass transportation costs, restoration of contaminated water resources, and mitigation of greenhouse gas emissions.

2009-085488 AB - We conducted the first synchronously coupled atmosphere-ocean general circulation model simulation from the Last Glacial Maximum to the Bolling-Allerod (BA) warming. Our model reproduces several major features of the deglacial climate evolution, suggesting a good agreement in climate sensitivity between the model and observations. In particular, our model simulates the abrupt BA warming as a transient response of the Atlantic meridional overturning circulation (AMOC) to a sudden termination of freshwater discharge to the North Atlantic before the BA. In contrast to previous mechanisms that invoke AMOC multiple equilibrium and Southern Hemisphere climate forcing, we propose that the BA transition is caused by the superposition of climatic responses to the transient CO (sub 2) forcing, the AMOC recovery from Heinrich Event 1, and an AMOC overshoot.

In this concept, an intermediate heat exchanger is used to transfer the heat from primary helium from the core to the secondary fluid, which can be helium, a nitrogen/helium mixture, or a molten salt. This paper assesses the issues pertaining to shell-and-tube and compact heat exchangers. A detailed thermal-hydraulic analysis was performed to calculate heat transfer, temperature distribution, and pressure drop inside both printed circuit and shell-and-tube heat exchangers. The analysis included evaluation of the role of key process parameters, geometrical factors in heat exchanger designs, and material properties of structural alloys. Calculations were performed for helium-to- helium, helium-to-helium/nitrogen, and helium-to-salt heat exchangers.

A guideline is needed to incorporate environmental effects in the ASME design rules to improve the performance reliability over long operating times. This paper summarizes the influence of sodium exposure on mechanical performance of selected austenitic stainless and ferritic/martensitic steels. Focus is on Type 316SS and mod.9Cr-1Mo. The sodium effects were evaluated by comparing the mechanical properties data in air and sodium. Carburization and decarburization were found to be the key factors that determine the tensile and creep properties of the steels. A beneficial effect of sodium exposure on fatigue life was observed under fully reversed cyclic loading in both austenitic stainless steels and ferritic/martensitic steels. However, when hold time was applied during cyclic loading, the fatigue life was significantly reduced. Based on the mechanical performance of the steels in sodium, consideration of sodium effects in high temperature structural design of advanced fast reactors is discussed.

MA and la migration test results are analyzed and reactions with the cladding are characterized. Remedies for reducing MA and la migration and reaction with cladding are reviewed. A possible method is proposed that includes the addition of a compound forming element such as indium or thallium in fuel. These elements preferentially form stable compounds with MA and la and should therefore reduce migration of MA and LA. As an intrinsic solution to the issue, the feasibility of the use of U-Pu-Mo alloy as fuel is studied. Unlike U-Pu-Zr, U-Pu-Mo consists of a single phase at typical fuel operation temperatures, and should have negligible fuel constituent redistribution and reduce MA and la migration.

Post-exposure examination included chemical analysis of interstitial impurities in V-4Cr-4Ti to monitor impurity transfer, and tensile tests at room temperature and 500 degree C. Microstructures were characterized by room-temperature electrical resistivity measurements and transmission electron microscopy. Oxygen was not depleted from V-4Cr-4Ti when nitrogen pickup occurred during lithium exposures. In spite of a significant increase in interstitial impurity concentration, the matrix interstitial solute content was reduced due to precipitation. Plate-shaped precipitates in the matrix and globular precipitates at grain boundaries were formed during lithium exposures at 700 degree C, while only globular precipitates were observed at grain boundaries at 800 degree C. Increases in strength, decreases in ductility, and reduced dynamic strain aging resulted. Ductility remained high after 1000 h exposures at both 700 and 800 degree C.

AN - 734144609; 19159128 AB - Monitoring expenses form a significant fraction of the costs associated with remediation of contaminated soil and groundwater sites. A novel monitoring method that could result in significant cost savings is the use of plants as monitoring devices; previous work indicates that plant tissue samples, especially trunk (core) and branch samples, can be used to delineate soil and groundwater plumes at phytoremediation sites. An important factor in reducing the uncertainty associated with this sampling method is development of a technique to analyze, both consistently and accurately, the chemicals stored in plant tissue samples. The present research presents a simple, robust, and inexpensive technique to recover most of the contaminant in plant branch tissue, irrespective of the age or species of the plant. Tricholoroethylene (TCE) was the chemical analyzed. A number of headspace and solvent extraction techniques in the literature were evaluated, including headspace extraction at different incubation times and temperatures and solvent extraction using hexane or hot methanol. Extraction using hot methanol was relatively fast, simple, and reliable; this method recovered more than 89% of the TCE present in branches of five different tree species.

Bioreduction experiments were conducted with combinations and varied concentrations of MR-1, nontronite, U(VI) and the electron shuttle anthraquinone-2,6-disulfonate (AQDS). Abiotic experiments were conducted to quantify U(VI) sorption to NAu-2, the reduction of U(VI) by chemically-reduced nontronite-Fe(II), and the oxidation of uraninite, U (super (IV)) O (sub 2(s)) , by nontronite-Fe(III). When we incubated S. oneidensis MR-1 at lower concentration (0.5X10 (super 8) cell mL (super -1) ) with nontronite (5.0g L (super -1) ) and U(VI) (1.0 mM), little U(VI) reduction occurred compared to nontronite-free incubations, despite the production of abundant Fe(II). The addition of AQDS to U(VI)- and nontronite-containing incubations enhanced both U(VI) and nontronite-Fe(III) reduction. While U(VI) was completely reduced by S. oneidensis MR-1 at higher concentration (1.0X10 (super 8) cell mL (super -1) ) in the presence of nontronite, increasing concentrations of nontronite led to progressively slower rates of U(VI) reduction. U(VI) enhanced nontronite-Fe(III) reduction and uraninite was oxidized by nontronite-Fe(III), demonstrating that U served as an effective electron shuttle from S. oneidensis MR-1 to nontronite-Fe(III). The electron-shuttling activity of U can explain the lack or delay of U(VI) reduction observed in the bulk solution. Little U(VI) reduction was observed in incubations that contained chemically-reduced nontronite-Fe(II), suggesting that biologic U(VI) reduction drove U valence cycling in these systems. Under the conditions used in these experiments, we demonstrate that iron-rich smectite may inhibit or delay U(VI) bioreduction.

We applied 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, and ASTER) using the arid Sinai Peninsula (SP; area: 61,000 km (super 2) ) and the Eastern Desert (ED; area: 220,000 km (super 2) ) of Egypt as our test sites. A two-fold exercise was conducted. Spatiotemporal 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 10 years (1998-2007). This was accomplished by using an automated cloud detection technique to identify clouds and to monitor their propagation prior to and throughout the identified precipitation events, and by examining changes in soil moisture (extracted from AMSR-E data) following the identification of clouds. For the investigated period, 246 of 327 events were verified in the SP, and 179 of 304 in the ED. A catchment-based, continuous, semi-distributed hydrologic model (Soil Water and Assessment Tool model; SWAT) was calibrated against observed runoff values from Wadi Girafi Watershed (area: 3350 km (super 2) ) and then used to provide a continuous simulation (1998-2007) of the overland flow, channel flow, transmission losses, evaporation on bare soils and evapo-transpiration, and groundwater recharge for the major (area: 2014-22,030 km (super 2) ) watersheds in the SP (Watir, El-Arish, Dahab, and Awag) and the ED (Qena, Hammamat, Asyuti, Tarfa, El-Quffa, El-Batur, Kharit, Hodein, and Allaqi) covering 48% and 51% of the total areas of the SP and the ED, respectively. For the investigated watersheds in the SP, the average annual precipitation, average annual runoff, and average annual recharge through transmission losses were found to be: 2955X10 (super 6) m (super 3) , 508X10 (super 6) m (super 3) (17.1% total precipitation (TP)), and 463X10 (super 6) m (super 3) (15.7% TP), respectively, whereas in the ED these values are: 807X10 (super 6) m (super 3) , 77.8X10 (super 6) m (super 3) (9.6% TP), and 171X10 (super 6) m (super 3) (21.2% TP), respectively. Results demonstrate the enhanced opportunities for groundwater development in the SP (compared to the ED) and highlight the potential for similar applications in arid areas elsewhere. The adopted remote sensing-based, regionalization approach is not a substitute for traditional methodologies that rely on extensive field 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.

The long half-life, high environmental mobility (as Tc(VII)O (sub 4) (super -) ) and its possible uptake into the food chain cause (super 99) Tc to be a significant environmental contaminant. In this study, we evaluated the role of Fe(II) in biologically reduced clay mineral, nontronite (NAu-2), in reducing Tc(VII)O (sub 4) (super -) to poorly soluble Tc(IV) species as a function of pH and Fe(II) concentration. The rate of Tc(VII) reduction by Fe(II) in NAu-2 was higher at neutral pH (pH 7.0) than at acidic and basic pHs when Fe(II) concentration was low (<1 mmol/g). The effect of pH, however, was insignificant at higher Fe(II) concentrations. The reduction of Tc(VII) by Fe(II) associated with NAu-2 was also studied in the presence of common subsurface oxidants including iron and manganese oxides, nitrate, and oxygen, to evaluate the effect of these oxidants on the enhancement and inhibition of Tc(VII) reduction, and reoxidation of Tc(IV). Addition of iron oxides (goethite and hematite) to the Tc(VII)-NAu-2 system, where Tc(VII) reduction was ongoing, enhanced reduction of Tc(VII), apparently as a result of re-distribution of reactive Fe(II) from NAu-2 to more reactive goethite/hematite surfaces. Addition of manganese oxides stopped further Tc(VII) reduction, and in case of K (super +) -birnessite, it reoxidized previously reduced Tc(IV). Nitrate neither enhanced reduction of Tc(VII) nor promoted reoxidation of Tc(IV). Approximately 11% of Tc(IV) was oxidized by oxygen. The rate and extent of Tc(IV) reoxidation was found to strongly depend on the nature of the oxidants and concentration of Fe(II). When the same oxidants were added to aged Tc reduction products (mainly NAu-2 and TcO (sub 2) .nH (sub 2) O), the extent of Tc(IV) reoxidation decreased significantly relative to fresh Tc(IV) products. Increasing NAu-2 concentration also resulted in the decreased extent of Tc(IV) reoxidation. The results were attributed to the effect of NAu-2 aggregation that effectively retained Tc(IV) in the solid and decreased its vulnerability to reoxidation. Overall, our results implied that bioreduced clay minerals could play an important role in reducing Tc(VII) and in maintaining the long-term stability of reduced Tc(IV).

The transportation sector relies solely on petroleum for its energy supply. The United States and China are the top two oil-importing countries. A major issue both countries face and are addressing is energy insecurity as a result of the demand for liquid fuels. Improvements in the energy efficiency of vehicles and the substitution of petroleum fuels with alternative fuels can help contain growth in the demand for transportation oil. Although most alternative transportation fuels - when applied to advanced vehicle technologies - can substantially reduce greenhouse emissions, coal-based liquid fuels may increase greenhouse gas emissions by twice as much as gasoline. Such technologies as carbon capture and storage may need to be employed to manage the greenhouse gas emissions of coal-based fuels. At present, there is no ideal transportation fuel option to solve problems related to transportation energy and greenhouse gas emissions. To solve these problems, research and development efforts are needed for a variety of transportation fuel options and advanced vehicle technologies.

The fuel temperature of this plate was higher than for most of the previous silicide-fuel tests where much smaller bubble growth was observed. The apparent conditions for the large bubble growth are high fission density (6.1 x 10 super(21) f/cm super(3)) and high fuel temperature (life-average 160 not equal to ). After analysis of PIE results of U0R040 and previous ANL test plates, a modification to the existing athermal bubble growth model appears to be necessary for high temperature application (above 130 not equal to ). A detailed analysis was performed using a model for the irradiation-induced viscosity of binary alloys to explain the effect of the increased fuel temperature. Threshold curves are proposed in terms of fuel temperature and fission density above which formation and interconnection of bubbles larger than 5 mu are possible.

The prediction of long-term S budgets of forest ecosystems under changing environmental conditions requires a precise quantification of all relevant soil S pools, comprising S species with different remobilization potential. In this study, the S speciation in topsoil horizons of a soil toposequence with different groundwater influence and oxygen availability was assessed by synchrotron-based X-ray absorption near-edge spectroscopy (XANES). Our investigation was conducted on organic (O, H) and mineral topsoil (A, AE) horizons of a Cambisol-Stagnosol-Histosol catena. We studied the influence of topography (i.e., degree of groundwater influence) and oxygen availability on the S speciation. Soil sampling and pretreatment were conducted under anoxic conditions. With increasing groundwater influence and decreasing oxygen availability in the sequence Cambisol-Stagnosol-Histosol, the C : S ratio in the humic topsoil decreased, indicating an enrichment of soil organic matter in S. Moreover, the contribution of reduced S species (inorganic and organic sulfides, thiols) increased systematically at the expense of intermediate S species (sulfoxide, sulfite, sulfone, sulfonate) and oxidized S species (ester sulfate, SOequation image). These results support the concept of different S-retention processes for soils with different oxygen availability. Sulfur contents and speciation in two water-logged Histosols subject to permanently anoxic and temporarily oxic conditions, respectively, were very different. In the anoxic Histosol, reduced S accounted for 57% to 67% of total S; in the temporarily oxic Histosol, reduced S was only 43% to 54% of total S. Again, the extent of S accumulation and the contribution of reduced S forms to total S closely reflected the degree of O2 availability. Our study shows that XANES is a powerful tool to elucidate key patterns of the biogeochemical S cycling in oxic and anoxic soil environments. In contrast to traditional wet-chemical methods, it particularly allows to distinguish organic S compounds in much more detail. It can be used to elucidate microbial S-metabolism pathways in soils with different oxygen availability by combining soil inventories and repeated analyses of a sample in different stages of field or laboratory incubation experiments under controlled boundary conditions and also to study (sub)microspatial patterns of S speciation in aggregated soils.

13267591 AB - The accessibility of precipitated, intragrain U(VI) in a contaminated sediment to microbial reduction was investigated to ascertain geochemical and microscopic transport phenomena controlling U(VI) bioavailability. The sediment was collected from the U.S. Department of Energy Hanford site, and contained uranyl precipitates within the mm-sized granitic lithic fragments in the sediment. Bioreduction was investigated in a culture of a dissimilatory metal-reducing bacterium, Shewanella oneidensis strain MR-1. Measurements of uranium concentration, speciation, and valence in aqueous and solid phases indicated that microbial reduction of intragrain U(VI) proceeded by two mechanisms: (1) sequentially coupled dissolution of intragrain uranyl precipitates, diffusion of dissolved U(VI) from intragrain regions, and microbial reduction of dissolved U(VI); and (2) U(VI) reduction in the intragrain regions by soluble, diffusible biogenic reductants. The bioreduction rate in the first pathway was over 3 orders of magnitude slower than that in comparable aqueous solutions containing aqueous U(VI) only. The slower bioreduction rate was attributed to (1) the release of calcium from the desorption/dissolution of calcium-containing minerals in the sediment, which subsequently altered U(VI) aqueous speciation and slowed U(VI) bioreduction and (2) alternative electron transfer pathways that reduced U(VI) in the intragrain regions and changed its dissolution and solubility behavior. The results implied that the overall rate of bioreduction of intragrain U(VI) will be influenced by the reactive mass transfer of U(VI) and biogenic reductants within intragrain regions, and geochemical reactions controlling major ion concentrations.

Superlattice reflections were resolved throughout the pressure (P) and temperature (T) range of the experiments, confirming that the crystal symmetry of CaPv is neither cubic nor tetragonal. A combination of analyses of the complete two-dimensional intensity datasets (photon energy from 20 to 160 keV and 2theta angle from 3.0 degrees to 9.0 degrees ) and Rietveld refinements at selected wavelengths revealed that the most likely space group of CaPv in the experimental P-T range, and therefore in the Earth's transition zone, is either Pbnm or Cmcm. The difference between these two space groups was too small to resolve with our technique.

The presence of CO (sub 2) affects mineral solubilities, fluid miscibility, and viscosity and wetting properties, and is expected to affect salt speciation. EXAFS measurements of RbBr-H (sub 2) O-CO (sub 2) fluids contained in corundum-osed synthetic fluid inclusions (SFLINCs) have been used to investigate the effect of CO (sub 2) on salt speciation at temperatures to 579 degrees C and pressures to around 0.26 GPa. Forward modelling indicates that solute dehydration is difficult to distinguish from up to around 40% of Rb-Br ion-pairing, so results refer to the total number of nearest neighbours, which are likely to be mostly O present in waters of hydration, but may also include Br, if ion pairing is present. Additionally, results relate to the number of well-ordered neighbours in the first shell, because nearest neighbours with a high degree of disorder may be present but contribute minimally to the EXAFS signal. Analysis of the EXAFS results at the Rb edge for the CO (sub 2) -free solution is consistent with previous work and shows that the number of nearest neighbours for Rb in CO (sub 2) -free solutions decreases from 6+ or -0.6 to 1.4+ or -0.1 as temperature increases from 20 to 534 degrees C. The decrease is accompanied by a decrease in Rb-x bondlengths of 0.05Aa, where x is the first shell scatterer. Results for the CO (sub 2) -bearing solution are different to those for the CO (sub 2) -free solution. The number of nearest neighbours is 16 and 22% less than for the CO (sub 2) -bearing solution at 312 and 445 degrees C respectively. Changes in the numbers of nearest neighbours correlate well with calculated changes in the bulk solution dielectric constant; CO (sub 2) -bearing and CO (sub 2) -free solutions lie on the same trend, which suggests that it may be possible to calculate the number of nearest neighbours from dielectric constant. Rb-x bondlengths for the CO (sub 2) -bearing solution are statistically indistinguishable to those for the CO (sub 2) -free inclusions. Results for Br are worse quality than for Rb so EXAFS analysis could not be completed, however XANES spectra for CO (sub 2) -free and CO (sub 2) -bearing solutions are consistent with solute dehydration similar to that recorded by the Rb spectra. The conclusions of this study provide support for the notion that CO (sub 2) has a fundamental effect on the mechanics of solubility, and that these effects should be incorporated into conceptual and quantitative thermodynamic models.

Creep deformation was characterized by measuring diametral changes of pressurized creep tubes before and after irradiation. It was found that the creep strain rate of the US Heat 832665 of V -4Cr -4Ti exhibited a linear relationship with stress up to [not, vert, similar]180 MPa at 425 C with a creep coefficient of 2.50 x 10 super(-6) MPa super(-1) dpa super(-1). A linear relationship between creep rate and applied stress was observed below [not, vert, similar]110 MPa at 600 C with a creep coefficient of 5.41 x 10 super(-6) MPa super(-1) dpa super(-1); non-linear creep behavior was observed above [not, vert, similar]110 MPa, and it may not be fully accounted by invoking thermal creep. The bilinear creep behavior observed in the same alloy irradiated in BR-10 was not observed in this study.

AN - 67129166; 19233199 AB - X-rays interact with biological matter and cause damage. Proteins and other macromolecules are damaged primarily by ionizing X-ray photons and secondarily by reactive radiolytic chemical species. In particular, protein molecules are damaged during X-ray diffraction experiments with protein crystals, which is, in many cases, a serious hindrance to structure solution. The local X-ray-induced structural changes of the protein molecule have been studied using a number of model systems. However, it is still not well understood whether these local chemical changes lead to global structural changes in protein and what the mechanism is. We present experimental evidence at atomic resolution indicating the movement of large parts of the protein globule together with bound water molecules in the early stages of radiation damage to the protein crystal. The data were obtained from a crystal cryocooled to approximately 100 K and diffracting to 1 A. The movement of the protein structural elements occurs simultaneously with the decarboxylation of several glutamate and aspartate residues that mediate contacts between moving protein structural elements and with the rearrangement of the water network. The analysis of the anisotropy of atomic displacement parameters reveals that the observed atomic movements occur at different rates in different unit cells of the crystal. Thus, the examination of the cooperative atomic movement enables us to better understand how radiation-induced local chemical and structural changes of the protein molecule eventually lead to disorder in protein crystals.

An electrochemical model, based on concentrated solution porous electrode theory, was developed to analyze the GITT experimental results and compare to the original GITT analytical theory. The GITT experimental studies on the oxide active material were conducted between 3.5 and 4.5 V vs. lithium, with the maximum lithium diffusion coefficient value being 10[super]-10 cm[super]2 s[super]-1 at 3.85 V. The lithium diffusion coefficient values obtained from this study agree favorably with the values obtained from an earlier electrochemical impedance spectroscopy study.

Hematite (Fe (sub 2) O (sub 3) ) is an important magnetic carrier mineral for deciphering planetary magnetism and a proxy for Fe in the planetary interiors. Here, we present synchrotron Moessbauer spectroscopy and X-ray diffraction combined with ab initio calculations for Fe (sub 2) O (sub 3) revealing the destruction of magnetic ordering at the hematite --> Rh (sub 2) O (sub 3) -II type (RhII) transition at 70 GPa and 300 K, and then the revival of magnetic ordering at the RhII --> postperovskite (PPv) transition after laser heating at 73 GPa. At the latter transition, at least half of Fe (super 3+) ions transform from LS to HS and Fe (sub 2) O (sub 3) changes from a semiconductor to a metal. This result demonstrates that some magnetic carrier minerals may experience a complex sequence of magnetic ordering changes during impact rather than a monotonic demagnetization. Also local Fe enrichment at Earth's core-mantle boundary will lead to changes in the electronic structure and spin state of Fe in silicate PPv. If the ultra-low-velocity zones are composed of Fe-enriched silicate PPv and/or the basaltic materials are accumulated at the lowermost mantle, high electrical conductivity of these regions will play an important role for the electromagnetic coupling between the mantle and the core.

For these materials crystallographic structures generally fall into 3 categories, which are 2 cubic forms and a hexagonal form. A unique clathrate hydrate structure, previously known only hypothetically, has been synthesized at high pressure and recovered at 77 K and ambient pressure in these experiments. These samples contain Xe as a guest atom and the details of this previously unobserved structure are described here, most notably the host-guest ratio is similar to the cubic Xe clathrate starting material. After pressure quench recovery to 1 atmosphere the structure shows considerable metastability with increasing temperature (T < 160 K) before reverting back to the cubic form. This evidence of structural complexity in compositionally similar clathrate compounds indicates that the reaction path may be an important determinant of the structure, and impacts upon the structures that might be encountered in nature.

To better understand the local electronic environment of high-spin Fe (super 2+) ions in ferropericlase near the transition, we obtained synchrotron Mossbauer spectra (SMS) of (Mg (sub 0.75) , Fe (sub 0.25) )O in externally heated and laser-heated diamond anvil cells at relevant high pressures and temperatures. Results show that the quadrupole splitting (QS) of the dominant high-spin Fe (super 2+) site decreases with increasing temperature at static high pressure. The QS values at constant pressure are fitted to a temperature-dependent Boltzmann distribution model, which permits estimation of the crystal-field splitting energy (Delta (sub 3) ) between the d (sub xy) and d (sub xz) or d (sub zy) orbitals of the t (sub 2g) states in a distorted octahedral Fe (super 2+) site. The derived Delta (sub 3) increases from approximately 36 meV at 1 GPa to 95 meV at 40 GPa, revealing that both high pressure and high temperature have significant effects on the 3d electronic shells of Fe (super 2+) in ferropericlase. The SMS spectra collected from the laser-heated diamond cells within the time window of 146 ns also indicate that QS significantly decreases at very high temperatures. A larger splitting of the energy levels at high temperatures and pressures should broaden the spin crossover in ferropericlase because the degeneracy of energy levels is partially lifted. Our results provide information on the hyperfine parameters and crystal-field splitting energy of high-spin Fe (super 2+) in ferropericlase at high pressures and temperatures, relevant to the electronic structure of iron in oxides in the deep lower mantle.

Tc is highly mobile in its most oxidized state [Tc(VII)O (sub 4) -] and less mobile in the reduced form [Tc(IV)O (sub 2) .nH (sub 2) O]. Here we investigate the potential for oxidation of Tc(IV) that was heterogeneously reduced by reaction with biogenic Fe(II) in two sediments differing in mineralogy and aggregation state; unconsolidated Pliocene-age fluvial sediment from the upper Ringold (RG) Formation at the Hanford Site and a clay-rich saprolite from the Field Research Center (FRC) background site on the Oak Ridge Site. Both sediments contained Fe(III) and Mn(III/IV) as redox active phases, but FRC also contained mass-dominant Fe-phyllosilicates of different types. Shewanella putrefaciens CN32 reduced Mn(III/IV) oxides and generated Fe(II) that was reactive with Tc(VII) in heat-killed, bioreduced sediment. After bioreduction and heat-killing, biogenic Fe(II) in the FRC exceeded that in RG by a factor of two. More rapid reduction rates were observed in the RG that had lower biogenic Fe(II), and less particle aggregation. EXAFS measurements indicated that the primary reduction product was a TcO (sub 2) -like phase in both sediments. The biogenic redox product Tc(IV) oxidized rapidly and completely in RG when contacted with air. Oxidation, in contrast, was slow and incomplete in the FRC, in spite of similar molecular scale speciation of Tc compared to RG. X-ray microprobe, electron microprobe, X-ray absorption spectroscopy, and micro X-ray diffraction were applied to the whole sediment and isolated Tc-containing particles. These analyses revealed that non-oxidizable Tc(IV) in the FRC existed as complexes with octahedral Fe(III) within intra-grain domains of 50-100 mu m-sized, Fe-containing micas presumptively identified as celadonite. The markedly slower oxidation rates in FRC as compared to RG were attributed to mass-transfer-limited migration of O (sub 2) into intra-aggregate and intraparticle domains where Tc(IV) existed; and the formation of unique, oxidation-resistant, intragrain Tc(IV)-Fe(III) molecular species.

Ordering of interfacial water and structural relaxations at the hematite (1 1 0) surface have been investigated in situ using high-resolution specular X-ray reflectivity. These measurements demonstrate that relaxations are constrained to primarily the top nearly equal 5 A of the surface. Near-surface iron atoms do not relax substantially, although the uppermost layer displays an increased distribution width, while the undercoordinated oxygens on the surface uniformly relaxed outward. Two sites of adsorbed water and additional layering of water farther from the surface were observed. Water fully covers the (1 1 0) surface and appears to form a continuous network extending into bulk solution, with positional order decreasing to that of a disordered bulk fluid within 1 nm. The arrangement of water is similar to that on the hematite (0 1 2) surface, which has a similar surface topography, although these surfaces display different vibrational amplitudes or positional disorder of adsorbed water molecules and average spacings of near-surface layered water. Comparison between these surfaces suggests that interfacial water ordering on hematite is controlled primarily by surface structure and steric constraints and that highly ordered water is likely common to most hematite-water interfaces.

Wood [1993] proposed that for most conceivable sulfur to carbon ratios, Fe (sub 3) C could be the major inner core component rather than iron-nickel alloy. A critical test for this hypothesis is to compare the density and sound velocities of Fe (sub 3) C with those of the inner core under corresponding pressure and temperature (P-T) conditions. To date, density of Fe (sub 3) C have been experimentally measured using X-ray diffraction at high pressure and ambient temperature [Scott et al., 2001, Li et al., 2002] or at high temperature and ambient pressure using neutron diffraction technique [Wood et al., 2004]. In our study, we carried out X-ray diffraction experiments of Fe (sub 3) C at simultaneous high pressure and high temperature (up to 18 GPa and 1523 K), using a T-cup device and synchrotron X-ray diffraction setup at beamline 13-ID of the Advanced Photon Source. Based on these results, we have developed a thermal equation of state of Fe (sub 3) C. Our results indicate that addition of carbon to iron can possibly provide a match in density to the Earth's inner core. We have also carried out nuclear resonant scattering measurements on (super 57) Fe-enriched Fe (sub 3) C up to 50 GPa at 300 K [Gao et al., 2008]. On the basis of our nuclear resonant inelastic X-ray scattering spectra and existing equation of state [Scott et al., 2001], we have derived the compressional wave velocity V (sub P) (km/s) = -3.99+1.29 I (density, g/cm (super 3) ) and the shear wave velocity V (sub S) (km/s) = 1.45+0.24 I (g/cm (super 3) ) for the high-pressure nonmagnetic phase. The addition of carbon to iron-nickel alloy brings V (sub P) and V (sub S) closer to seismic observations, supporting carbon as a principal light element in the Earth's inner core.

We have performed new experiments in the Fe-calcite-H (sub 2) O system at pressures from 2 to 10 GPa and temperatures from 500 to 2000 identical with C. We used both laser and resistively heated diamond anvil cells for all experiments and a combination of Raman spectroscopy and synchrotron X-ray diffraction for analysis. Our motivation was to explore a more reducing system than previous experiments in order to favor the methane-forming reaction. We were particularly interested to see if, by improving the methane yield, we can detect the formation of heavier hydrocarbons. As expected, by using Fe rather than FeO as the reducing agent, we observe increased methane production as indicated by Raman spectroscopy. Powder X-ray diffraction data confirm previous results that the oxidation of iron at these conditions produces magnetite. We also detect Ca(OH) (sub 2) and a few diffraction lines from an as yet unidentified phase. Furthermore, we have conducted experiments with Au-lined gaskets to conclusively demonstrate that steel gaskets are not necessary for these reactions to proceed. Finally, spectroscopic evidence suggests the formation of a methane-hydrate structure upon temperature quench from 5 GPa and 650 identical with C (by room temperature the pressure had decreased to 2 GPa; we cannot further constrain the P-T conditions of this clathrate formation from our current dataset). Notably, we have not detected the presence of hydrocarbons heavier than methane.

Common modifications include acid activation and organic treatment. Acid activation has been used for decades to prepare bleaching earths for adsorbing impurities from edible and industrial oils. Organic treatment has sparked an explosive interest in a class of materials called polymer-clay nanocomposites (PCNs). The most commonly used clay mineral in PCNs is montmorillonite, which is the main constituent of bentonite. PCN materials are used for structural reinforcement and mechanical strength, for gas permeability barriers, as flame retardants, and to minimize surface erosion (ablation). Other specialty applications include use as conducting nanocomposites and bionanocomposites.

Fuel burnup was limited to less than 7.8 at.% U in order to capture the fuel-swelling stage prior to irradiation-induced recrystallization. The model couples the calculation of the time evolution of the average intergranular bubble radius and number density to the calculation of the intergranular bubble-size distribution based on differential growth rate and sputtering coalescence processes. Recent results on TEM analysis of intragranular bubbles in U-Mo were used to set the irradiation-induced diffusivity and re-solution rate in the bubble-swelling model. Using these values, good agreement was obtained for intergranular bubble distribution compared against measured post-irradiation examination (PIE) data using grain-boundary diffusion enhancement factors of 15-125, depending on the Mo concentration. This range of enhancement factors is consistent with values obtained in the literature.

However, the effects of light water reactor (LWR) coolant environments were not explicitly considered in the development of the design curves. The existing fatigue-strain-versus-life (-N) data indicate potentially significant effects of LWR coolant environments on the fatigue resistance of pressure vessel and piping steels. Under certain environmental and loading conditions, fatigue lives in water relative to those in air can be a factor of 15 lower for austenitic stainless steels and a factor of 30 lower for carbon and low-alloy steels. This paper reviews the current technical basis for the understanding of the fatigue of piping and pressure vessel steels in LWR environments. The existing fatigue -N data have been evaluated to identify the various material, environmental, and loading parameters that influence fatigue crack initiation and to establish the effects of key parameters on the fatigue life of these steels. Statistical models are presented for estimating fatigue life as a function of material, loading, and environmental conditions. An environmental fatigue correction factor for incorporating the effects of LWR environments into ASME Code fatigue evaluations is described. This paper also presents a critical review of the ASME Code fatigue design margins of 2 on stress (or strain) and 20 on life and assesses the possible conservatism in the current choice of design margins.

13267230 AB - Global Hg emissions are presented for the year 2050 under a variety of assumptions about socioeconomic and technology development. We find it likely that Hg emissions will increase in the future. The range of 2050 global Hg emissions is projected to be 2390-4860 Mg, compared to 2006 levels of 2480 Mg, reflecting a change of -4% to +96%. The main driving force for increased emissions is the expansion of coal-fired electricity generation in the developing world, particularly Asia. Our ability to arrest the growth in Hg emissions is limited by the relatively low Hg removal efficiency of the current generation of emission control technologies for coal-fired power plants (flue-gas desulfurization). Large-scale deployment of advanced Hg sorbent technologies, such as Activated Carbon Injection, offers the promise of lowering the 2050 emissions range to 1670-3480 Mg, but these technologies are not yet in commercial use. The share of elemental Hg in total emissions will decline from today's levels of 65% to 50-55% by 2050, while the share of divalent Hg will increase. This signals a shift from long-range transport of elemental Hg to local deposition of Hg compoundsthough emissions of both species could increase under the worst case.

This study uses Beijing as a case study and focuses on CO, HC, and NOx emissions from hot-stabilized activities of light-duty vehicles. The target year is 2004. The total quantity of emissions, emission intensity, temporal distribution of emissions by hour, and spatial distribution of emissions at 1 km X 1 km resolution are presented and compared with results from other inventory methods commonly used in China. The results show that the total emissions from light-duty vehicles in the Beijing urban area in 2004 were 1141 Mg of CO per day, 48 Mg of HC per day, and 32 Mg of NOx per day. Pollutant emissions from mobile sources show temporal and spatial variation trends that are consistent with the characteristics of people's activities. The inventory developed in this study reflects the influences of vehicle driving patterns in traffic on vehicle emissions on a road link basis, and it could be used to evaluate the impacts of traffic-related emission control measures in China.

AN - 66961029; 19240333 AB - The high-brilliance X-ray beams from undulator sources at third-generation synchrotron facilities are excellent tools for solving crystal structures of important and challenging biological macromolecules and complexes. However, many of the most important structural targets yield crystals that are too small or too inhomogeneous for a ;standard' beam from an undulator source, approximately 25-50 microm (FWHM) in the vertical and 50-100 microm in the horizontal direction. Although many synchrotron facilities have microfocus beamlines for other applications, this capability for macromolecular crystallography was pioneered at ID-13 of the ESRF. The National Institute of General Medical Sciences and National Cancer Institute Collaborative Access Team (GM/CA-CAT) dual canted undulator beamlines at the APS deliver high-intensity focused beams with a minimum focal size of 20 microm x 65 microm at the sample position. To meet growing user demand for beams to study samples of 10 microm or less, a ;mini-beam' apparatus was developed that conditions the focused beam to either 5 microm or 10 microm (FWHM) diameter with high intensity. The mini-beam has a symmetric Gaussian shape in both the horizontal and vertical directions, and reduces the vertical divergence of the focused beam by 25%. Significant reduction in background was achieved by implementation of both forward- and back-scatter guards. A unique triple-collimator apparatus, which has been in routine use on both undulator beamlines since February 2008, allows users to rapidly interchange the focused beam and conditioned mini-beams of two sizes with a single mouse click. The device and the beam are stable over many hours of routine operation. The rapid-exchange capability has greatly facilitated sample screening and resulted in several structures that could not have been obtained with the larger focused beam.

We used the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model to examine the well-to-wheels (WTW) emissions of five criteria pollutants (VOCs, NO sub(x), PM sub(1) sub(0), PM sub(2) sub(.) sub(5), and CO) for nine vehicle/fuel systems: (1) conventional gasoline vehicles; (2) conventional diesel vehicles; (3) ethanol (E85) flexible-fuel vehicles (FFVs) fueled with corn-based ethanol; (4) E85 FFVs fueled with switchgrass-based ethanol; (5) gasoline hybrid vehicles (HEVs); (6) diesel HEVs; (7) electric vehicles (EVs) charged using the average U.S. generation mix; (8) EVs charged using the California generation mix; and (9) hydrogen fuel cell vehicles (FCVs). Pollutant emissions were separated into total and urban emissions to differentiate the locations of emissions, and emissions were presented by sources. The results show that WTW emissions of the vehicle/fuel systems differ significantly, in terms of not only the amounts but also with respect to locations and sources, both of which are important in evaluating alternative vehicle/fuel systems. E85 FFVs increase total emissions but reduce urban emissions by up to 30% because the majority of emissions are released from farming equipment, fertilizer manufacture, and ethanol plants, all of which are located in rural areas. HEVs reduce both total and urban emissions because of the improved fuel economy and lower emissions. While EVs significantly reduce total emissions of VOCs and CO by more than 90%, they increase total emissions of PM sub(1) sub(0) and PM sub(2) sub(.) sub(5) by 35-325%. However, EVs can reduce urban PM emissions by more than 40%. FCVs reduce VOCs, CO, and NO sub(x) emissions, but they increase both total and urban PM emissions because of the high process emissions that occur during hydrogen production. This study emphasizes the importance of specifying a thorough life-cycle emissions inventory that can account for both the locations and sources of the emissions to assist in achieving a fair comparison of alternative vehicle/fuel options in terms of their environmental impacts.

Calcite transforms from R3c to R3m at about T c = 1,240 K. A CO3 group occupies, statistically, two positions with equal frequency in the disordered R3m phase, but with unequal frequency in the partially ordered R3c phase. One position for the CO3 group is rotated by 180 degrees with respect to the other. The unequal occupancy of the two orientations in the partially ordered R3c phase is obtained directly from the occupancy factor, x, for the O1 site and gives rise to the order parameter, S = 2x - 1. The a cell parameter shows a negative thermal expansion at low T, followed by a plateau region at higher T, then a steeper contraction towards T c, where the CO3 groups disorder in a rapid process. Using a modified Bragg-Williams model, fits were obtained for the order parameter S, and for the intensities of the (113) and (211) reflections.

13267009 AB - Metal and hydrogen ion acidity and extreme nitrate concentrations at Department of Energy legacy waste sites pose challenges for successful in situ U and Tc bioimmobilization. In this study, we investigated a potential in situ biobarrier configuration designed to neutralize pH and remove nitrate and radionuclides from nitric acid-, U-, and Tc-contaminated groundwater for over 21 months. Ethanol additions to groundwater flowing through native sediment and crushed limestone effectively increased pH (from 4.7 to 6.9), promoted removal of 116 mM nitrate, increased sediment biomass, and immobilized 94% of total U. Increased groundwater pH and significant U removal was also observed in a control column that received no added ethanol. Sequential extraction and XANES analyses showed U in this sediment to be solid-associated U(VI), and EXAFS analysis results were consistent with uranyl orthophosphate (UO2)3(PO4)2.4H2O(s), which may control U solubility in this system. Ratios of respiratory ubiquinones to menaquinones and copies of dissimilatory nitrite reductase genes, nirS and nirK, were at least 1 order of magnitude greater in the ethanol-stimulated system compared to the control, indicating that ethanol addition promoted growth of a largely denitrifying microbial community. Sediment 16S rRNA gene clone libraries showed that Betaproteobacteria were dominant (89%) near the source of influent acidic groundwater, whereas members of Gamma- and Alphaproteobacteria and Bacteroidetes increased along the flow path as pH increased and nitrate concentrations decreased, indicating spatial shifts in community composition as a function of pH and nitrate concentrations. Results of this study support the utility of biobarriers for treating acidic radionuclide- and nitrate-contaminated groundwater.

In these experiments, all of the electron donors, including echanol, glucose, methanol, and methanol with added humic acids, stimulated the reduction and immobilization of aqueous uranium by the indigenous microbial community. Uranium loss from solution began after the completion of nitrate reduction but essentially concurrent with sulfate reduction. When electron donor concentrations were normalized for their equivalent electron donor potential yield, the rates of uranium reduction were nearly equivalent for all treatments (0.55-0.95 mu mol L (super -1) d (super -1) ). Uranium reduction with methanol proceeded after a 15-d longer lag time relative to that of ethanol or glucose. Significant differences were not found with the inclusion of humic acids. The extent of U reduction in sediment slurries measured by XANES at various time periods after the start of the experiment increased in the order of ethanol (5-7% reduced at 77 and 153 d), glucose (49% reduced at 53 d), and methanol (93% reduced at 90 d). The microbial diversity of ethanol- and methanol-amended microcosms in their late stage of U reduction was analyzed with 16S rRNA gene amplification. Members of the Geobacteraceae were found in all microcosms as well as other potential uranium-reducing organisms, such as Clostridium and Desulfosporosinus. The effectiveness of methanol relative to ethanol at reducing aqueous and sediment-hosted uranium suggests that bioremediation strategies that encourage fermentative poising of the subsurface to a lower redox potential may be more effective for long-term uranium immobilization as compared with selecting an electron donor that is efficiently metabolized by known uranium-reducing microorganisms.

Results showed that majority of Cr(VI) mass was easily removed from the sediments (equilibrium site Kd varied from 0 to 0.33 mL g-1 and equilibrium site fraction was greater than 95%). Long tailings of time-dependent Cr(VI) concentrations above maximum contaminant level of 1.9 *mmol L-1 were also observed (kinetically controlled fraction Kd and desorption reaction half-lives varied from 0 to 45 mL g-1, and from 76.1 to 126 h, respectively). Microscopic and spectroscopic measurements confirmed that Cr was concentrated within fine-grained coatings in small areas mainly rich in phyllosilicates that contained both Cr(III) and Cr(VI). However, Cr(VI) reduction was neither significant nor complete. Under slightly alkaline and oxic conditions, contaminant Cr in the sediments occurred: (i) In the highly mobile pool (over 95% of total Cr); (ii) In the slow and time-dependent releasing pool, which served as long-term source of contamination; (iii) As reduced Cr(III) which most likely formed during Cr(VI) reaction with aqueous, sorbed, or structural Fe(II).

Our experiments with natural siderite reveal spin pairing of d-orbital electrons of Fe (super 2+) at 43 GPa, as evidenced by a sharp volume collapse of about 10%. The initially colorless crystals assume an intense green color after the transition, which progressively turns to red above 60 GPa. We present clear evidence for the instability of an intermediate spin state in siderite at ambient temperature. At the transition pressure, domains of high and low spin siderite coexist. The unit cell volume difference between magnesite and siderite is significantly decreased by the spin transition, enhancing the solubility between the two calcite-type minerals. A siderite component in magnesite at lower mantle pressure would significantly increase its density and slightly increase the carbonate bulk modulus.

Samples were synthesized in situ in the laser-heated diamond cell under reducing conditions. The dominant spin state of iron in perovskite is high spin at pressures below 50 GPa. Above 50 GPa, the spectra shows severe changes which can be explained by appearance of two distinct iron sites with similar site weightings. One site has Mossbauer parameters consistent with high spin Fe (super 2+) , while the other has the parameters previously interpreted as intermediate spin. The latter intermediate-spin assignment is not unique, as similar Mossbauer parameters have been reported for high spin Fe (super 2+) in almandine at ambient pressure. However, our data do not rule out the existence of low-spin iron, which may exist with a smaller fraction and explain the observation of lower spin moments in the X-ray emission spectroscopy of perovskite at high pressure. From these considerations, our preferred interpretation is that iron in perovskite is mixed or high spin to at least 2000 km depths in the mantle, consistent with computational results. Our study also reveals that reducing conditions do not inhibit the formation of Fe (super 3+) in perovskite at deep-mantle pressures.

Evaluation of the time spectra reveals two distinct iron sites, which are well distinguished by their hyperfine fields. The dominant site is consistent with an Fe (super 3+) -like site in a high spin state. The second site is characterized by a small negative isomer shift with respect to alpha -iron and no quadrupole splitting, consistent with a metallic iron phase. Combined with SEM/EDS analyses of the quenched assemblage, our results are consistent with the presence of a metallic iron phase co-existing with a ferric-rich PPv.

The effective Clapeyron slope of the transition from high to low spin is strongly positive in pressure-temperature space and broadens with high temperature. This introduces a net spin-state driving density difference for both upwellings and downwellings. In 2-D cylindrical geometry spin-buoyancy dominantly enhances the positive thermal buoyancy of plumes. Although the additional buoyancy does not fundamentally alter large-scale dynamics, the Nusselt number increases by 5-10%, and vertical velocities by 10-40% in the lower mantle. Advective heat transport is more effective and temperatures in the core-mantle boundary region are reduced by up to 12%. Our findings are relevant to the stability of lowermost mantle structures.

Photosynthetic CO (sub 2) capture from the atmosphere and storage of the C in aboveground and belowground biomass and in soil organic and inorganic forms can be exploited for safe and affordable greenhouse gas (GHG) mitigation [Watson et al., 2000]. Nevertheless, C sequestration in the terrestrial biosphere has not been seriously pursued since its introduction in the Kyoto Protocol over a decade ago. Concerns have been raised that C sequestration in the biosphere is finite and not permanent, that it is difficult to measure and monitor, that there would be "carbon leakage" outside of the mitigation activity, and that any attention paid to environmental sequestration would be a distraction from the central issue of reducing GHG emissions from energy production and use. International accord and success in reducing emissions from the energy system are not coming easily, and concerns about climate change are growing. It is time to reevaluate all available options that might not be permanent yet have the potential to buy time, bridging to a future when new energy system technologies and a transformed energy infrastructure can fully address the climate challenge. Terrestrial sequestration is one option large enough to make a contribution in the coming decades using proven land management methods and with the possibility that new technologies could significantly enhance the opportunity.

Samples were collected from the two thick (>5 m) coal seams in the coalfield and have been analysed for methane and carbon dioxide sorption capacity, petrography, pore size distribution, specific surface area and porosity. Specific surface area (SSA) available for carbon dioxide adsorption, extrapolated to a probe size of 4 A, ranged from 1.25 x 10 (super 6) cm (super -1) to 4.26 x 10 (super 6) cm (super -1) with total porosity varying from 16% to 25%. Porosity was found to be predominantly composed of microporosity, which contributed the majority of the available SSA. Although considerable variation was seen between samples, the results fit well with published rank trends. Gas holding capacity at the reservoir pressure (approximately 4 MPa) ranged from 2.63 to 4.18 m (super 3) /t for methane on a dry, ash-free basis (daf) and from 22.00 to 23.72 m (super 3) /t daf for carbon dioxide. The resulting ratio of CO (sub 2) :CH (sub 4) ranged from 5.7 to 8.6, with an average of 6.7:1. Holding capacities for both methane and carbon dioxide on a dry ash free basis (daf) were found to be correlated with sample microporosity. However, holding capacities for the two gases on an as analysed (aa) basis (that is including mineral matter and moisture), showed no such correlation. Carbon dioxide (aa) does show a negative correlation with both specific surface area and microporosity. As the coals have low inorganic matter content, the reversal is thought to be related to moisture which is likely concentrated in the pore size range 12.5-125 A. Methane holding capacity, both daf and aa, correlates with macroporosity, thus suggesting that the holding capacity of micropores is diminished by the presence of moisture in the pores.

Travel day data from the 2001 National Household Travel Survey (NHTS) were analyzed to identify the share of vehicle miles of travel (VMT) that could be transferred to grid electricity. Various PHEV charge-depleting (CD) ranges were evaluated, and 100% CD mode and potential blended modes were analyzed. The NHTS data were also examined to evaluate the potential for PHEV battery charging multiple times a day. Data from the 2005 American Housing Survey (AHS) were analyzed to evaluate the availability of garages and carports for at-home charging of the PHEV battery. The AHS data were also reviewed by census region and household location within or outside metropolitan statistical areas. To illustrate the lag times involved, the historical new vehicle market share increases for the diesel power train in France (a highly successful case) and the emerging hybrid electric vehicles in the United States were examined. A new vehicle technology substitution model is applied to illustrate a historically plausible successful new PHEV market share expansion. The trends in U.S. light-duty vehicle sales and light-duty vehicle stock were evaluated to estimate the time required for hypothetical successful new PHEVs to achieve the ultimately attainable share of the existing vehicle stock. Only when such steps have been accomplished will the full oil savings potential for the nation be achieved.

Any effort to transition to another fuel with different properties-with both advantages and disadvantages- must make similar adjustments. This paper discusses the existing gaso-line refueling infrastructure and its evolution. It then describes the hydrogen delivery scenario analysis model, an Excel-based tool that calculates the levelized cost of delivering hydrogen from a central production facility to a vehicle by the use of currently available technologies and a typical profile of vehicle use and fueling demand. The results are shown for a status quo, or gasoline-centric case, in which demand reflects the current gasoline-based system and supply responds accordingly, and a hydrogen-centric case, in which some of those patterns are altered. The paper highlights fueling requirements that are particularly problematic for hydrogen and concludes with a discussion of alternative fueling paradigms.

In light of increasing regulation and government incentives for IR, this research analyzed the full fuel cycle effects of contemporary approaches. It compared emissions, energy use, and proximity to urban populations for nine alternatives, including idling, electrified parking spaces, auxiliary power units, and several combinations of these. It also compared effects for the United States and seven states: California, Florida, Illinois, New York, Texas, Virginia, and West Virginia. U.S. average emissions impacts from all onboard IR options were found to be lower than those from a 2007-compliant idling truck. Total particulate emissions from electrified parking spaces were found to be greater than those from a 2007 truck, but such emissions generally occurred in areas with low population density. The lowest energy use, carbon dioxide emissions, and nitrogen oxide emissions are seen with a direct-fired heater combined with electrified parking spaces for cooling, and the lowest particulate-matter emissions were found with a direct-fired heater combined with an onboard device for cooling. As expected, state-to-state variations in the climate and grid fuel mix influence the impacts of the full fuel cycle from IR technologies, and the most effective choice for one location may be less effective elsewhere.

RadTrac has been developed at Argonne National Laboratory as an integrated system for the detection, localization, identification, and tracking of radioactive sources in real time. The system is based on a network of radiation detectors and advanced signal-processing algorithms. Features include video surveillance, automated tracking, easy setup, and logging of all data and images. This paper describes the advanced algorithms that were developed and implemented for source detection, localization, and tracking in real time. In the physio-spatial integration approach to source localization, counts from multiple detectors are processed according to the underlying physics linking these counts to obtain the probability that a source is present at any point in space.

As such, a primary mission of DHS is to protect the public against the use of these devices and to assist state and local responders in finding, locating, and identifying these types of devices and materials used to manufacture these devices. This assistance from DHS to state and local responders comes in the form of grant money to procure radiation detection equipment. In addition to this grant program, DHS has supported the development of American National Standards Institute standards for radiation detection equipment and has conducted testing of commercially available instruments. This paper identifies the types and kinds of commercially available equipment that can be used to detect and identify radiological material for use in traditional search applications as well as primary and secondary screening of personnel, vehicles, and cargo containers. In doing so, key considerations for the conduct of operations are described as well as critical features of the instruments for specific applications. The current state of commercial instruments is described for different categories of detection equipment including personal radiation detectors, radioisotope identifiers, man-portable detection equipment, and radiation portal monitors. In addition, emerging technologies are also discussed, such as spectroscopic detectors and advanced spectroscopic portal monitors.

This research effort couples computational fluid dynamics (CFD) modeling with a variety of experimental observations to provide a valid detailed analysis of the flow within the centrifugal contactor. CFD modeling of the free surface flow in the annular mixing zone using the volume-of-fluid method combined with large eddy simulation of turbulence was found to have very good agreement with the experimental measurements. A detailed comparative analysis of the flow and mixing with different housing vane geometries (four straight vanes, eight straight vanes, and curved vanes) was performed. Two additional variations on the eight straight vane geometry were also simulated. This analysis determined that at the simulated moderate flow rate the four straight mixing vane geometry has greater mixing and fluid residence time as compared to the other mixing vane configurations.

More specifically, we subjected this film to a very brief ( reversible reaction min) hydrogen plasma treatment in a sputter ion plating system to determine if the friction and wear behavior would change. All tests were performed in dry nitrogen using a pin-on-disk machine under a 0.5 N load and at 0.1 m/s sliding velocity. The friction coefficient of as-deposited DLC film was high and unsteady (varying between 0.1 and 0.8) and it could only last for a sliding distance of ~12 m. However, after the hydrogen plasma treatment, the same film was able to provide a friction coefficient of less than 0.01 and lasted for a sliding distance of more than 450 m. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was used to elucidate the nature and extent of the chemical changes that occurred during hydrogen plasma treatment. 2- and 3-D TOF-SIMS images of such surfaces revealed the formation of a hydrogen-rich top surface layer during the hydrogen-plasma treatment. Based on the combined results of tribological and surface analytical studies, we provided a mechanistic explanation for the very critical role of hydrogen on friction and wear of DLC films.

Five approaches were employed to allocate the coproducts: a displacement approach; two allocation approaches, one based on the energy value and the other based on the market value; and two hybrid approaches that integrated the displacement and allocation methods. The relative rankings of soybean-based fuels in terms of energy and environmental impacts were different under the different approaches, and the reasons were analyzed. Results from the five allocation approaches showed that although the production and combustion of soybean-based fuels might increase total energy use, they could have significant benefits in reducing fossil energy use (>52%), petroleum use (>88%), and GHG emissions (>57%) relative to petroleum fuels. This study emphasized the importance of the methods used to deal with coproduct issues and provided a comprehensive solution for conducting a life-cycle assessment of fuel pathways with multiple coproducts.

The radiative contribution to heat transport is usually assumed to be negligible. Here, we report the near-infrared and optical absorption spectra of silicate perovskite, the main constituent of the lower mantle, to 125 gigapascals. Silicate perovskite remains quite transparent up to the pressures at the core-mantle boundary. Estimates of radiative thermal conductivity derived from these spectra approach 10 watts meter (super -1) kelvin (super -1) at lowermost mantle conditions, implying that heat conduction is dominated by radiation. However, the increase in radiative conductivity with temperature (T) is less pronounced than expected from a T (super 3) dependency.

The structure was refined in space group P4 (sub 2) /n. A room-temperature structure, obtained with synchrotron high-resolution powder X-ray-diffraction (HRPXRD) data, has unit-cell parameters a 12.06503(1), c 7.58360(1) Aa, and V 1103.906(2) Aa (super 3) . Moreover, the average bond-distances , and are equal to 1.606(2), 1.726(2) and 1.612(2) Aa, respectively, and correspond to occupancies T1 = [Al (sub 0) Si (sub 1) ], T2 = [Al (sub 0.87) Si (sub 0.13) ], and T3 = [Al (sub 0.02) Si (sub 0.98) ]. At 902 degrees C, , and are equal to 1.591(5), 1.683(8) and 1.686(7) Aa, respectively, and correspond to T1 = [Al (sub 0) Si (sub 1) ], T2 = [Al (sub 0.55) Si (sub 0.45) ], and T3 = [Al (sub 0.57) Si (sub 0.43) ]. At 902 degrees C, the T1 site remains fully occupied by Si atoms, whereas the disorder at the T2 and T3 sites is close to being complete. Several structural parameters show a break at 200 degrees C, which corresponds to disorder of the Na and Ca (= M) atoms. On cooling, the structure does not go back to the initial structural state; some T2-T3 and Na-Ca disorder are quenched in. The type-b reflections that give rise to antiphase-domain boundaries (APBs) are present at all temperatures; they arise from Cl-CO (sub 3) order, instead of Al-Si order. At 902 degrees C, except for the anions, there is no difference between the structure of Me (sub 32.9) in space group P4 (sub 2) /n and that of Me (sub 80) in space group I4/m.

The purpose is to illustrate that crystal structures obtained by HRPXRD are comparable to those obtained by SXTL. The comparisons indicate important and significant differences between the structures obtained by the two methods. The cell parameters obtained by Rietveld refinements using HRPXRD data appear of superior quality to those obtained by SXTL. The distances in pure SiO (sub 4) tetrahedron in quartz, sodalite, and tremolite are 1.6081(3), 1.6100(2), and 1.620(1) Aa, respectively. These values are affected by interstitial cations. In meionite Me (sub 79.6) , the average and distances are 1.647(1) and 1.670(1) Aa, respectively, and they indicate that the occupancies are (Al (sub 0.28) Si (sub 0.72) ) for T1 where the atoms are partially ordered and (Al (sub 0.45) Si (sub 0.55) ) for T2 site where the atoms are nearly disordered, based on sodalite Si-O and Al-O distances of 1.6100(2) and 1.7435(2) Aa, respectively.

However, many of the color maps used in volume rendering provide questionable value in knowledge representation and are non-perceptual thus biasing data analysis or even obscuring information. These drawbacks, coupled with our need for realistic anatomical volume rendering for teaching and surgical planning, has motivated us to explore the auto-generation of color maps that combine natural colorization with the perceptual discriminating capacity of grayscale. As evidenced by the examples shown that have been created by the algorithm described, the merging of perceptually accurate and realistically colorized virtual anatomy appears to insightfully interpret and impartially enhance volume rendered patient data.

Two forms of gaseous Hg were included in the model: elemental Hg (HG(0) and oxidized or reactive Hg (HGO). We simulated three different emission scenarios to evaluate the model's sensitivity. One scenario included no emissions from China, while the others were based on different estimates of Hg emissions in China. The results indicated, in general, that when Hg emissions were included, HG(0) concentrations increased both locally and globally. Increases in Hg concentrations in the United States were greatest during spring and summer, by as much as 7%. Ratios of calculated concentrations of Hg and CO near the source region in eastern Asia agreed well with ratios based on measurements. Increases similar to those observed for HG(0) were also calculated for deposition of HGO. Calculated increases in wet and dry deposition in the United States were 5-7% and 5-9%, respectively.

It is found in all organisms and has been proposed to serve as an energy source in a pre-ATP world. This ubiquitous and abundant biopolymer plays numerous and vital roles in metabolism and regulation in prokaryotes and eukaryotes, but the underlying molecular mechanisms for most activities of polyP remain unknown. In prokaryotes, the synthesis and utilization of polyP are catalyzed by 2 families of polyP kinases, PPK1 and PPK2, and polyphosphatases. Here, we present structural and functional characterization of the PPK2 family. Proteins with a single PPK2 domain catalyze polyP-dependent phosphorylation of ADP to ATP, whereas proteins containing 2 fused PPK2 domains phosphorylate AMP to ADP. Crystal structures of 2 representative proteins, SMc02148 from Sinorhizobium meliloti and PA3455 from Pseudomonas aeruginosa, revealed a 3-layer alpha / beta / alpha sandwich fold with an alpha -helical lid similar to the structures of microbial thymidylate kinases, suggesting that these proteins share a common evolutionary origin and catalytic mechanism. Alanine replacement mutagenesis identified 9 conserved residues, which are required for activity and include the residues from both Walker A and B motifs and the lid. Thus, the PPK2s represent a molecular mechanism, which potentially allow bacteria to use polyP as an intracellular energy reserve for the generation of ATP and survival.

tracking fluid-rock interaction in gold deposits AN - 50469392; 2009-036218 AB - We used mu -XANES spectroscopy to measure the oxidation state of europium in-situ at near-mu m resolution in hydrothermal scheelite from the giant Archean gold deposits of Kalgoorlie, Western Australia. By combining these measurements with mu -XRF imaging, it is possible to distinguish inhomogeneities in Eu (super 2+) /Eu (super 3+) ratios that developed during mineral precipitation from the effects of subsequent hydrothermal alteration and weathering. Thermodynamic analysis reveals that under the conditions typical of the formation of many Au deposits, the Eu (super 2+) /Eu (super 3+) ratio in the hydrothermal fluid is highly sensitive to pH. The range in pH calculated from the Eu (super 2+) /Eu (super 3+) ratios in the analyzed scheelite corresponds to a maximum in Au solubility under the ore-forming conditions, and suggests buffering of pH by the CO (sub 2(aq)) -rich fluid. The primary heterogeneity of the Kalgoorlie scheelite most likely results from pH oscillating between fluid- and rock-buffered conditions, and reflects the dynamics of the hydrothermal system.

A key component of these models is the ability to predict whole-organism activity concentrations in a wide range of wildlife. In this paper, we compare the whole-organism activity concentrations predicted by eight models participating within the IAEA Environmental Modelling for Radiation Safety programme for a range of radionuclides to terrestrial and freshwater organisms. In many instances, there was considerable variation, ranging over orders of magnitude, between the predictions of the different models. Reasons for this variability (including methodology, data source and data availability) are identified and discussed. The active participation of groups responsible for the development of key models within this exercise is a useful step forward in providing the transparency in methodology and data provenance required for models which are either currently being used for regulatory purposes or which may be used in the future. The work reported in this paper, and supported by other findings, demonstrates that the largest contribution to variability between model predictions is the parameterisation of their transfer components. There is a clear need to focus efforts and provide authoritative compilations of those data which are available.

Cytochromes c - electron transfer proteins carrying one or more hemes covalently bound to the polypeptide chain - are essential in most organisms. However, they are one of the most recalcitrant classes of proteins with respect to heterologous expression because post-translational incorporation of hemes is required for proper folding and stability. We have addressed this challenge by designing two families of vectors (total of 6 vectors) suitable for ligation-independent cloning and developing a pipeline for expression and solubility analysis of cytochromes c. This system has been validated by expression analysis of thirty genes from Shewanella oneidensis coding for cytochromes c or cytochromes c-type domains predicted to have 1-4 hemes. Out of 30 targets, 26 (87%) were obtained in soluble form in one or more vectors. This work establishes a methodology for high-throughput expression of this class of proteins and provides a clone resource for the microbiological and functional genomics research communities.
