TY - JOUR T1 - Operando Grazing Incidence Small-Angle X-ray Scattering/X-ray Diffraction of Model Ordered Mesoporous Lithium-Ion Battery Anodes. AN - 1863702845; 28145689 AB - Emergent lithium-ion (Li+) batteries commonly rely on nanostructuring of the active electrode materials to decrease the Li+ ion diffusion path length and to accommodate the strains associated with the insertion and de-insertion of Li+, but in many cases these nanostructures evolve during electrochemical charging-discharging. This change in the nanostructure can adversely impact performance, and challenges remain regarding how to control these changes from the perspective of morphological design. In order to address these questions, operando grazing-incidence small-angle X-ray scattering and X-ray diffraction (GISAXS/GIXD) were used to assess the structural evolution of a family of model ordered mesoporous NiCo2O4 anode films during battery operation. The pore dimensions were systematically varied and appear to impact the stability of the ordered nanostructure during the cycling. For the anodes with small mesopores (≈9 nm), the ordered nanostructure collapses during the first two charge-discharge cycles, as determined from GISAXS. This collapse is accompanied by irreversible Li-ion insertion within the oxide framework, determined from GIXD and irreversible capacity loss. Conversely, anodes with larger ordered mesopores (17-28 nm) mostly maintained their nanostructure through the first two cycles with reversible Li-ion insertion. During the second cycle, there was a small additional deformation of the mesostructure. This preservation of the ordered structure lead to significant improvement in capacity retention during these first two cycles; however, a gradual loss in the ordered nanostructure from continuing deformation of the ordered structure during additional charge-discharge cycles leads to capacity decay in battery performance. These multiscale operando measurements provide insight into how changes at the atomic scale (lithium insertion and de-insertion) are translated to the nanostructure during battery operation. Moreover, small changes in the nanostructure can build up to significant morphological transformations that adversely impact battery performance through multiple charge-discharge cycles.

AN - 1870987463; 28223687 AB - A major challenge limiting the practical applications of nanomaterials is that the activities of nanostructures (NSs) increase with reduced size, often sacrificing their stability in the chemical environment. Under oxidative conditions, NSs with smaller sizes and higher defect densities are commonly expected to oxidize more easily, since high-concentration defects can facilitate oxidation by enhancing the reactivity with O2 and providing a fast channel for oxygen incorporation. Here, using FeO NSs as an example, we show to the contrary, that reducing the size of active NSs can drastically increase their oxidation resistance. A maximum oxidation resistance is found for FeO NSs with dimensions below 3.2 nm. Rather than being determined by the structure or electronic properties of active sites, the enhanced oxidation resistance originates from the size-dependent structural dynamics of FeO NSs in O2. We find this dynamic size effect to govern the chemical properties of active NSs.

AN - 1861583508; 28103035 AB - We report a tunable library of N,N,N'-trisubstituted selenourea precursors and their reaction with lead oleate at 60-150 °C to form carboxylate-terminated PbSe nanocrystals in quantitative yields. Single exponential conversion kinetics can be tailored over 4 orders of magnitude by adjusting the selenourea structure. The wide range of conversion reactivity allows the extent of nucleation ([nanocrystal] = 4.6-56.7 μM) and the size following complete precursor conversion (d = 1.7-6.6 nm) to be controlled. Narrow size distributions (σ = 0.5-2%) are obtained whose spectral line widths are dominated (73-83%) by the intrinsic single particle spectral broadening, as observed using spectral hole burning measurements. The intrinsic broadening decreases with increasing size (fwhm = 320-65 meV, d = 1.6-4.4 nm) that derives from exciton fine structure and exciton-phonon coupling rather than broadening caused by the size distribution.

Aqueous PEO45 -PDEAm41 -PDBAm12 solutions, which undergo a thermally induced sphere-to-worm transition in dilute solution, were found to reversibly form soft (G'≈10 Pa) free-standing physical gels after 10 min at 55 °C. PEO45 -PDEAm89 -PDBAm12 copolymer solutions, which undergo a thermally induced transition from spheres to large compound micelles (LCM) in dilute solution, underwent phase separation after heating at 55 °C for 10 min owing to sedimentation of LCMs. The reversibility of LCM formation was investigated as a non-specific method for removal of a water-soluble dye from aqueous solution. The composition and size of the central responsive block in these polymers dictate the microscopic and macroscopic response of the polymer solutions as well as the rates of transition between assemblies.

AN - 1857754193; 28073258 AB - The leading edge of catalysis research motivates physical understanding of the growth of nanoscale oxide structures on different supporting oxide materials that are themselves also nanostructured. This research opens up for consideration a diverse range of facets on the support material, versus the single facet typically involved in wide-area growth of thin films. Here, we study the growth of ceria nanoarchitectures on practical anatase titania powders as a showcase inspired by recent experiments. Density functional theory (DFT)-based methods are employed to characterize and rationalize the broad array of low energy nanostructures that emerge. Using a bottom-up approach, we are able to identify and characterize the underlying mechanisms for the facet-dependent growth of various ceria motifs on anatase titania based on formation energy. These motifs include 0D clusters, 1D chains, 2D plates, and 3D nanoparticles. The ceria growth mode and morphology are determined by the interplay of several factors including the role of the common cation valence, the interface template effect for different facets of the anatase support, enhanced ionic binding for more compact ceria motifs, and the local structural flexibility of oxygen ions in bridging the interface between anatase and ceria structures.

However, current representations vary markedly between TBMs, contributing uncertainty to projections of global carbon fluxes. Here we compared the representation of photosynthesis in seven TBMs by examining leaf and canopy level responses of photosynthetic CO sub(2) assimilation (A) to key environmental variables: light, temperature, CO sub(2) concentration, vapor pressure deficit and soil water content. We identified research areas where limited process knowledge prevents inclusion of physiological phenomena in current TBMs and research areas where data are urgently needed for model parameterization or evaluation. We provide a roadmap for new science needed to improve the representation of photosynthesis in the next generation of terrestrial biosphere and Earth system models.

Here, we use real-time environmental transmission electron microscopy (E-TEM) to observe nucleation and self-organization of CNTs into vertically aligned forests. Upon introduction of the carbon source, we observe a large scatter in the onset of nucleation of individual CNTs and the ensuing growth rates. Experiments performed at different temperatures and catalyst particle densities show the critical role of CNT density on the dynamics of self-organization; low-density CNT nucleation results in the CNTs becoming pinned to the substrate and forming random networks, whereas higher density CNT nucleation results in self-organization of the CNTs into bundles that are oriented perpendicular to the substrate. We also find that mechanical coupling between growing CNTs alters their growth trajectory and shape, causing significant deformations, buckling, and defects in the CNT walls. Therefore, it appears that CNT-CNT coupling not only is critical for self-organization but also directly influences CNT quality and likely the resulting properties of the forest. Our findings show that control of the time-distributed kinetics of CNT nucleation and bundle formation are critical to manufacturing well-organized CNT assemblies and that E-TEM can be a powerful tool to investigate the mesoscale dynamics of CNT networks.

AN - 1851287194; 27936537 AB - Multiwalled carbon nanotubes (MWNTs) represent a promising support medium for electrocatalysts, especially Pt nanoparticles (NPs). The advantages of using MWNTs include their large surface area, high conductivity, as well as long-term stability. Surface functionalization of MWNTs with various terminal groups, such as -COOH, -SH, and -NH2, allows for rational electronic tuning of catalyst-support interactions. However, several issues still need to be addressed for such systems. First, over the course of an electrochemical run, catalyst durability can decrease, due in part to metal NP dissolution, a process facilitated by the inherently high surface defect concentration within the support. Second, the covalent functionalization treatment of MWNTs adopted by most groups tends to lead to a loss of structural integrity of the nanotubes (NTs). To mitigate for all of these issues, we have utilized two different attachment approaches (i.e., covalent versus noncovalent) to functionalize the outer walls of pristine MWNTs and compared the catalytic performance of as-deposited ultrathin (<2 nm) 1D Pt nanowires with that of conventional Pt NPs toward the oxygen reduction reaction (ORR). Our results demonstrated that the electrochemical activity of Pt nanostructures immobilized onto functionalized carbon nanotube (CNT) supports could be dramatically improved by using ultrathin Pt nanowires (instead of NPs) with noncovalently (as opposed to covalently) functionalized CNT supports. Spectroscopic evidence corroborated the definitive presence of charge transfer between the metal catalysts and the underlying NT support, whose direction and magnitude are a direct function of (i) the terminal chemistry as well as (ii) the attachment methodology, both of which simultaneously impact upon the observed electrocatalytic performance. Specifically, the use of a noncovalent π-π stacking method coupled with a -COOH terminal moiety yielded the highest performance results, reported to date, for any similar system consisting of Pt (commercial NPs or otherwise) deposited onto carbon-based supports, a finding of broader interest toward the fabrication of high-performing electrocatalysts in general.

The atmosphere at that time contained more carbon dioxide than at any other period thereafter. Carbon dioxide sustained greenhouse conditions, accelerated the weathering of a primitive crust, and may have led to conditions conducive to forming the building blocks of life. The conversion of inorganic carbon and nitrogen to the essential building blocks of life may have been facilitated by clays, zeolites, sulfides, and metal alloys that had been formed as the crust reacted with a warm and carbonated (seltzer) ocean. Geochemical modeling constrains the conditions favorable for the formation of these potential mineral catalysts.

Vertical velocity observations are presented using cumulative frequency histograms and weighted mean profiles to provide insights in a manner suitable for global climate model scale comparisons (spatial domains from 20km to 60km). Convective profile sensitivity to changes in environmental conditions and seasonal regime controls is also considered. Aggregate and ensemble average vertical velocity, convective area fraction, and mass flux profiles, as well as magnitudes and relative profile behaviors, are found consistent with previous studies. Updrafts and downdrafts increase in magnitude with height to midlevels (6 to 10km), with updraft area also increasing with height. Updraft mass flux profiles similarly increase with height, showing a peak in magnitude near 8km. Downdrafts are observed to be most frequent below the freezing level, with downdraft area monotonically decreasing with height. Updraft and downdraft profile behaviors are further stratified according to environmental controls. These results indicate stronger vertical velocity profile behaviors under higher convective available potential energy and lower low-level moisture conditions. Sharp contrasts in convective area fraction and mass flux profiles are most pronounced when retrievals are segregated according to Amazonian wet and dry season conditions. During this deployment, wet season regimes favored higher domain mass flux profiles, attributed to more frequent convection that offsets weaker average convective cell vertical velocities. Key Points * Characterization of vertical velocity, area fraction, and mass flux profiles for Amazon convection * Profiles aligned to be statistically representative of ensemble and aggregate convective properties to GCM domain scales * Convective profiles indicate significant sensitivity to environmental forcing, wet and dry season regime controls JF - Journal of Geophysical Research: Atmospheres AU - Giangrande, Scott E AU - Toto, Tami AU - Jensen, Michael P AU - Bartholomew, Mary Jane AU - Feng, Zhe AU - Protat, Alain AU - Williams, Christopher R AU - Schumacher, Courtney AU - Machado, Luiz AD - Environmental and Climate Sciences Department, Brookhaven National Laboratory, Upton, New York, USA.

AN - 1835356323; 27543389 AB - Botulinum neurotoxins (BoNT) are among the most poisonous substances known, and of the 7 serotypes (A-G) identified thus far at least 4 can cause death in humans. The goal of this work was identification of inhibitors that specifically target the light chain catalytic site of the highly pathogenic but lesser-studied E serotype (BoNT/E). Large-scale computational screening, employing the program DOCK, was used to perform atomic-level docking of 1.4 million small molecules to prioritize those making favorable interactions with the BoNT/E site. In particular, 'footprint similarity' (FPS) scoring was used to identify compounds that could potentially mimic features on the known substrate tetrapeptide RIME. Among 92 compounds purchased and experimentally tested, compound C562-1101 emerged as the most promising hit with an apparent IC50 value three-fold more potent than that of the first reported BoNT/E small molecule inhibitor NSC-77053. Additional analysis showed the predicted binding pose of C562-1101 was geometrically and energetically stable over an ensemble of structures generated by molecular dynamic simulations and that many of the intended interactions seen with RIME were maintained. Several analogs were also computationally designed and predicted to have further molecular mimicry thereby demonstrating the potential utility of footprint-based scoring protocols to help guide hit refinement.

AN - 1816864206; 27421079 AB - High-resolution transmission electron microscopy (HRTEM) examination of nanoparticles requires their placement on some manner of support - either TEM grid membranes or part of the material itself, as in many heterogeneous catalyst systems - but a systematic quantification of the practical imaging limits of this approach has been lacking. Here we address this issue through a statistical evaluation of how nanoparticle size and substrate thickness affects the ability to resolve structural features of interest in HRTEM images of metallic nanoparticles on common support membranes. The visibility of lattice fringes from crystalline Au nanoparticles on amorphous carbon and silicon supports of varying thickness was investigated with both conventional and aberration-corrected TEM. Over the 1-4nm nanoparticle size range examined, the probability of successfully resolving lattice fringes differed significantly as a function both of nanoparticle size and support thickness. Statistical analysis was used to formulate guidelines for the selection of supports and to quantify the impact a given support would have on HRTEM imaging of crystalline structure. For nanoparticles ≥1nm, aberration-correction was found to provide limited benefit for the purpose of visualizing lattice fringes; electron dose is more predictive of lattice fringe visibility than aberration correction. These results confirm that the ability to visualize lattice fringes is ultimately dependent on the signal-to-noise ratio of the HRTEM images, rather than the point-to-point resolving power of the microscope. This study provides a benchmark for HRTEM imaging of crystalline supported metal nanoparticles and is extensible to a wide variety of supports and nanostructures.

AN - 1813627817; 27353886 AB - Botulinum neurotoxins (BoNTs) are the most poisonous biological substance known to humans. They cause flaccid paralysis by blocking the release of acetylcholine at the neuromuscular junction. Here, we report a number of small molecule non-peptide inhibitors of BoNT serotype E. The structure-activity relationship and a pharmacophore model are presented. Although non-peptidic in nature, these inhibitors mimic key features of the uncleavable substrate peptide Arg-Ile-Met-Glu (RIME) of the SNAP-25 protein. Among the compounds tested, most of the potent inhibitors bear a zinc-chelating moiety connected to a hydrophobic and aromatic moiety through a carboxyl or amide linker. All of them show low micromolar IC50 values.

The growth depends on various environmental conditions, and in particular, on flow rates. Modeling the evolution of such properties is difficult both at the porescale where the phase morphology can be distinguished, as well as during upscaling to the corescale effective properties. Experimental data on biofilm growth is also limited because its collection can interfere with the growth, while imaging itself presents challenges.In this paper we combine insight from imaging, experiments, and numerical simulations and visualization. The experimental dataset is based on glass beads domain inoculated by biomass which is subjected to various flow conditions promoting the growth of biomass and the appearance of a biofilm phase. The domain is imaged and the imaging data is used directly by a computational model for flow and transport. The results of the computational flow model are upscaled to produce conductivities which compare well with the experimentally obtained hydraulic properties of the medium. The flow model is also coupled to a newly developed biomass-nutrient growth model, and the model reproduces morphologies qualitatively similar to those observed in the experiment.

MC3E science objectives were motivated by the need to improve our understanding of midlatitude continental convective cloud system life cycles, microphysics, and GPM precipitation retrieval algorithms. To achieve these objectives, a multiscale surface- and aircraft-based in situ and remote sensing observing strategy was employed. A variety of cloud and precipitation events were sampled during MC3E, of which results from three deep convective events are highlighted. Vertical structure, air motions, precipitation drop size distributions, and ice properties were retrieved from multiwavelength radar, profiler, and aircraft observations for a mesoscale convective system (MCS) on 11 May. Aircraft observations for another MCS observed on 20 May were used to test agreement between observed radar reflectivities and those calculated with forward-modeled reflectivity and microwave brightness temperatures using in situ particle size distributions and ice water content. Multiplatform observations of a supercell that occurred on 23 May allowed for an integrated analysis of kinematic and microphysical interactions. A core updraft of 25 m s super(-1) supported growth of hail and large raindrops. Data collected during the MC3E campaign are being used in a number of current and ongoing research projects and are available through the ARM and NASA data archives.

Uropathogenic strains of Escherichia coli use this pathway to assemble P and type 1 pili, which facilitate colonization of the kidney and bladder, respectively. Pilus assembly requires a periplasmic chaperone and outer membrane protein termed the usher. The chaperone allows folding of pilus subunits and escorts the subunits to the usher for polymerization into pili and secretion to the cell surface. Based on previous structures of mutant versions of the P pilus chaperone PapD, it was suggested that the chaperone dimerizes in the periplasm as a self-capping mechanism. Such dimerization is counterintuitive because the chaperone G1 strand, important for chaperone-subunit interaction, is buried at the dimer interface. Here, we show that the wild-type PapD chaperone also forms a dimer in the crystal lattice; however, the dimer interface is different from the previously solved structures. In contrast to the crystal structures, we found that both PapD and the type 1 pilus chaperone, FimC, are monomeric in solution. Our findings indicate that pilus chaperones do not sequester their G1 beta -strand by forming a dimer. Instead, the chaperones may expose their G1 strand for facile interaction with pilus subunits. We also found that the type 1 pilus adhesin, FimH, is flexible in solution while in complex with its chaperone, whereas the P pilus adhesin, PapGII, is rigid. Our study clarifies a crucial step in pilus biogenesis and reveals pilus-specific differences that may relate to biological function. IMPORTANCE Pili are critical virulence factors for many bacterial pathogens. Uropathogenic E. coli relies on P and type 1 pili assembled by the chaperone/usher pathway to adhere to the urinary tract and establish infection. Studying pilus assembly is important for understanding mechanisms of protein secretion, as well as for identifying points for therapeutic intervention. Pilus biogenesis is a multistep process. This work investigates the oligomeric state of the pilus chaperone in the periplasm, which is important for understanding early assembly events. Our work unambiguously demonstrates that both PapD and FimC chaperones are monomeric in solution. We further demonstrate that the solution behavior of the FimH and PapGII adhesins differ, which may be related to functional differences between the two pilus systems.

AN - 1809048610; 27355699 AB - Amyloid-β (Aβ) is a 39-42 residue protein produced by the cleavage of the amyloid precursor protein (APP), which subsequently aggregates to form cross-β amyloid fibrils that are a hallmark of Alzheimer's disease (AD). The most prominent forms of Aβ are Aβ1-40 and Aβ1-42, which differ by two amino acids (I and A) at the C-terminus. However, Aβ42 is more neurotoxic and essential to the etiology of AD. Here, we present an atomic resolution structure of a monomorphic form of AβM01-42 amyloid fibrils derived from over 500 (13)C-(13)C, (13)C-(15)N distance and backbone angle structural constraints obtained from high field magic angle spinning NMR spectra. The structure (PDB ID: 5KK3 ) shows that the fibril core consists of a dimer of Aβ42 molecules, each containing four β-strands in a S-shaped amyloid fold, and arranged in a manner that generates two hydrophobic cores that are capped at the end of the chain by a salt bridge. The outer surface of the monomers presents hydrophilic side chains to the solvent. The interface between the monomers of the dimer shows clear contacts between M35 of one molecule and L17 and Q15 of the second. Intermolecular (13)C-(15)N constraints demonstrate that the amyloid fibrils are parallel in register. The RMSD of the backbone structure (Q15-A42) is 0.71 ± 0.12 Å and of all heavy atoms is 1.07 ± 0.08 Å. The structure provides a point of departure for the design of drugs that bind to the fibril surface and therefore interfere with secondary nucleation and for other therapeutic approaches to mitigate Aβ42 aggregation.

AN - 1806438844; 27376686 AB - After more than a decade, it is still unknown whether the plasmon-mediated growth of silver nanostructures can be extended to the synthesis of other noble metals, as the molecular mechanisms governing the growth process remain elusive. Herein, we demonstrate the plasmon-driven synthesis of gold nanoprisms and elucidate the details of the photochemical growth mechanism at the single-nanoparticle level. Our investigation reveals that the surfactant polyvinylpyrrolidone preferentially adsorbs along the nanoprism perimeter and serves as a photochemical relay to direct the anisotropic growth of gold nanoprisms. This discovery confers a unique function to polyvinylpyrrolidone that is fundamentally different from its widely accepted role as a crystal-face-blocking ligand. Additionally, we find that nanocrystal twinning exerts a profound influence on the kinetics of this photochemical process by controlling the transport of plasmon-generated hot electrons to polyvinylpyrrolidone. These insights establish a molecular-level description of the underlying mechanisms regulating the plasmon-driven synthesis of gold nanoprisms.

AN - 1807279940; 27327863 AB - Chemical doping has been demonstrated to be an effective method for producing high-quality, large-area graphene with controlled carrier concentrations and an atomically tailored work function. The emergent optoelectronic properties and surface reactivity of carbon nanostructures are dictated by the microstructure of atomic dopants. Co-doping of graphene with boron and nitrogen offers the possibility to further tune the electronic properties of graphene at the atomic level, potentially creating p- and n-type domains in a single carbon sheet, opening a gap between valence and conduction bands in the 2-D semimetal. Using a suite of high-resolution synchrotron-based X-ray techniques, scanning tunneling microscopy, and density functional theory based computation we visualize and characterize B-N dopant bond structures and their electronic effects at the atomic level in single-layer graphene grown on a copper substrate. We find there is a thermodynamic driving force for B and N atoms to cluster into BNC structures in graphene, rather than randomly distribute into isolated B and N graphitic dopants, although under the present growth conditions, kinetics limit segregation of large B-N domains. We observe that the doping effect of these BNC structures, which open a small band gap in graphene, follows the B:N ratio (B > N, p-type; B < N, n-type; B═N, neutral). We attribute this to the comparable electron-withdrawing and -donating effects, respectively, of individual graphitic B and N dopants, although local electrostatics also play a role in the work function change.

AN - 1804197159; 27295061 AB - In this work, we use electron energy-loss spectroscopy to map the complete plasmonic spectrum of aluminum nanodisks with diameters ranging from 3 to 120 nm fabricated by high-resolution electron-beam lithography. Our nanopatterning approach allows us to produce localized surface plasmon resonances across a wide spectral range spanning 2-8 eV. Electromagnetic simulations using the finite element method support the existence of dipolar, quadrupolar, and hexapolar surface plasmon modes as well as centrosymmetric breathing modes depending on the location of the electron-beam excitation. In addition, we have developed an approach using nanolithography that is capable of meV control over the energy and attosecond control over the lifetime of volume plasmons in these nanodisks. The precise measurement of volume plasmon lifetime may also provide an opportunity to probe and control the DC electrical conductivity of highly confined metallic nanostructures. Lastly, we show the strong influence of the nanodisk boundary in determining both the energy and lifetime of surface plasmons and volume plasmons locally across individual aluminum nanodisks, and we have compared these observations to similar effects produced by scaling the nanodisk diameter.

The study is focused on the definition of probabilities and distribution functions for the defined taxonomy of sky conditions. Correlations of the Clearness Index are investigated with different meteorological variables, to finally highlight that the only important correlation besides the irradiance is given by the relative humidity, though with a negative pattern. In conclusion, the analysis has shown that the three constraints of the standard test conditions (1000 W/m super(2), 25 degree C, air mass of 1.5 global) normally applied for laboratory characterisation of PV modules are actually never simultaneously met outdoor.

Although integration and meta-analysis of these samples has become routine in the plant research community, it is often hampered by a lack of metadata or differences in annotation styles of different labs. In this study, we carefully selected and integrated 6057 Arabidopsis microarray expression samples from 304 experiments deposited to the Gene Expression Omnibus (GEO) at the National Center for Biotechnology Information (NCBI). Metadata such as tissue type, growth conditions and developmental stage were manually curated for each sample. We then studied the global expression landscape of the integrated data set and found that samples of the same tissue tend to be more similar to each other than to samples of other tissues, even in different growth conditions or developmental stages. Root has the most distinct transcriptome, compared with aerial tissues, but the transcriptome of cultured root is more similar to the transcriptome of aerial tissues, as the cultured root samples lost their cellular identity. Using a simple computational classification method, we showed that the tissue type of a sample can be successfully predicted based on its expression profile, opening the door for automatic metadata extraction and facilitating the re-use of plant transcriptome data. As a proof of principle, we applied our automated annotation pipeline to 708 RNA-seq samples from public repositories and verified the accuracy of our predictions with sample metadata provided by the authors. Significance Statement A total of 6057 Arabidopsis microarray expression samples from 304 experiments deposited to NCBI GEO were computationally integrated and consistently re-annotated. We demonstrate that the tissue type of microarray samples can be accurately predicted from the expression profile. Thus missing or incomplete metadata of transcriptome data sets can be automatically reconstructed.

AN - 1790458934; 27165117 AB - We have studied (001) surface terminated cerium oxide nanoparticles grown on a ruthenium substrate using physical vapor deposition. Their morphology, shape, crystal structure, and chemical state are determined by low-energy electron microscopy and micro-diffraction, scanning probe microscopy, and synchrotron-based X-ray absorption spectroscopy. Square islands are identified as CeO2 nanocrystals exhibiting a (001) oriented top facet of varying size; they have a height of about 7 to 10 nm and a side length between about 50 and 500 nm, and are terminated with a p(2 × 2) surface reconstruction. Micro-illumination electron diffraction reveals the existence of a coincidence lattice at the interface to the ruthenium substrate. The orientation of the side facets of the rod-like particles is identified as (111); the square particles are most likely of cuboidal shape, exhibiting (100) oriented side facets. The square and needle-like islands are predominantly found at step bunches and may be grown exclusively at temperatures exceeding 1000 °C.

Currently used or proposed cathode recycling processes are multistep procedures which involve sequences of mechanical, thermal, and chemical leaching, where only the base material is recovered and significant processing is required to generate a recycled electrode structure. Another significant issue facing lithium based batteries is capacity fade due to structural degradation of the electroactive material upon extending cycling. Herein, inspired by heterogeneous catalyst thermal regeneration strategies, we present a new facile cathode recycling process, where previously used cathodes are removed from a cell, heat treated, and then inserted into a new cell restoring the delivered capacity and cycle life. An environmentally sustainable manganese based material is employed, where binder-free self-supporting (BFSS) electrodes are prepared using a fibrous, high aspect ratio manganese oxide active material. After 200 discharge-charge cycles, the recycled BFSS electrodes display restored crystallinity and oxidation state of the manganese centers with the resulting electrochemistry (capacity and coulombic efficiency) reminiscent of freshly prepared BFSS cathodes. Notably, the BFSS electrode structure is robust with no degradation during the cell disassembly, electrode recovery, washing, and heat treatment steps; thus no post-processing is required for the recycled electrode. This work shows for the first time that a thermal regeneration method previously employed in catalyst systems can fully restore battery electrochemical performance, demonstrating a novel electrode recycling process which could open up new possibilities for energy storage devices with extended electrode lifecycles.

The as-prepared gamma -Fe sub(2)O sub(3)/C was introduced to the application of wastewater treatment, and methylene blue (MB) was used to simulate the oxidative degradation process of organic pollutants. Carbon coexisted in the gamma -Fe sub(2)O sub(3)/C nanocomposite could well serve as a preconcentrator of MB dyes and consequently the catalytic performance was strongly enhanced. Moreover, the gamma -Fe sub(2)O sub(3)/C catalyst could be easily recycled by magnetic separation for effective reuse. This work not only prepared gamma -Fe sub(2)O sub(3)/C nanocomposite by a quite facile method, but also successfully employed it as a catalyst for degradation of organic pollutants under mild condition.

AN - 1772145933; 26840127 AB - Lasing in solution-processed nanomaterials has gained significant interest because of the potential for low-cost integrated photonic devices. Still, a key challenge is to utilize a comprehensive knowledge of the system's spectral and temporal dynamics to design low-threshold lasing devices. Here, we demonstrate intrinsic lasing (without external cavity) at low-threshold in an ultrathin film of coupled, highly crystalline nanospheres with overall thickness on the order of ∼λ/4. The cavity-free geometry consists of ∼35 nm zinc oxide nanospheres that collectively localize the in-plane emissive light fields while minimizing scattering losses, resulting in excitonic lasing with fluence thresholds at least an order of magnitude lower than previous UV-blue random and quantum-dot lasers (<75 μJ/cm(2)). Fluence-dependent effects, as quantified by subpicosecond transient spectroscopy, highlight the role of phonon-mediated processes in excitonic lasing. Subpicosecond evolution of distinct lasing modes, together with three-dimensional electromagnetic simulations, indicate a random lasing process, which is in violation of the commonly cited criteria of strong scattering from individual nanostructures and an optically thick sample. Subsequently, an electron-hole plasma mechanism is observed with increased fluence. These results suggest that coupled nanostructures with high crystallinity, fabricated by low-cost solution-processing methods, can function as viable building blocks for high-performance optoelectronics devices.

Previous studies have shown that oxygen release can be reduced by the migration of transition metal cations from octahedral sites to tetrahedral sites during heating. Such site-preferred migration is determined by the electronic structure of cations. Taking advantage of the unique electronic structure of the environmental friendly Fe, this is selected as substitution element in a high energy density material LiNi sub(0.5)Mn sub(1.5)O sub(4) to improve the thermal stability. The optimized LiNi sub(0.33)Mn sub(1.33)Fe sub(0.33)O sub(4) material shows significantly improved thermal stability compared with the unsubstituted one, demonstrated by no observed oxygen release at temperatures as high as 500 degree C. Due to the electrochemical contribution of Fe, the high energy density feature of LiNi sub(0.5)Mn sub(1.5)O sub(4) is well preserved. A naturally abundant and environmentally benign element, iron (Fe), is introduced into LiNi sub(0.5)Mn sub(1.5)O sub(4) spinel based on an understanding of the relationship between the electronic structure of transition metal elements and the safety characteristics of cathodes. The LiNi sub(0.33)Mn sub(1.34)Fe sub(0.33)O sub(4) material shows significant improvements in safety characteristics by inhibiting oxygen release upon heating, while maintaining the high energy density of LiNi sub(0.5)Mn sub(1.5)O sub(4).

In this work, using combined X-ray, UV-vis, and Moessbauer spectroscopic approaches, we were able to identify and quantify the long-time sought ferric speciation over time during ferric oxyhydroxide formation in partially-neutralized ferric nitrate solutions ([Fe (super 3+) ] = 0.2 M, 1.8 < pH < 3). Results demonstrate that Fe exists mainly as Fe(H (sub 2) O) (sub 6) (super 3+) , mu -oxo aquo dimers and ferrihydrite, and that with time, the mu -oxo dimer decreases while the other two species increase in their concentrations. No larger Fe oligomers were detected. Given that the structure of the mu -oxo dimer is incompatible with those of all Fe oxides and oxyhydroxides, our results suggest that reconfiguration of the mu -oxo dimer structure occurs prior to further condensation leading up to the nucleation of ferrihydrite.

(super 238) U is assigned a half-life of (4.4683 + or - 0.0096) Ga, i.e. a decay constant lambda (sub 238) = (0.155125 + or - 0.000333) Ga (super -1) . The coverage factor is k = 2 for this and all other estimates presented here. The (super 238) U half-life can be used as a reference for the half-lives/decay constants of all other isotopic geochronometers. A revision of the half-life of (super 235) U based on intercomparison of natural geological samples is premature. The improved repeatability of mass spectrometric measurements has revealed Type B uncertainties that had been dismissed as subordinate in the past. The combined uncertainty of these as yet incompletely charted and quantified sources of Type B uncertainty may be no smaller than the currently accepted uncertainty of the alpha counting experiments. A provisional value for the (super 234) U half-life can be calculated with the assumption of secular equilibrium in the analyzed natural samples. This assumption has not yet been verified independently and its metrological traceability appears sub-optimum. A Type B evaluation suggests that the ca. 0.17% offset between the N( (super 234) U)/N( (super 238) U) number-ratios of the natural samples used to estimate the (super 235) U half-life and those of the four samples used to estimate the (super 234) U half-life should be compounded into the standard measurement uncertainty of the latter. The resulting provisional uncertainty interval (k = 2) for the (super 234) U half-life is (244.55-247.77) ka, corresponding to lambda (sub 234) = (2.8203-2.8344) Ma (super -1) .

AN - 1733190498; 26318574 AB - Metallic tungsten (W) was initially assumed to be environmentally benign and a green alternative to lead. However, subsequent investigations showed that fishing weights and munitions containing elemental W can fragment and oxidize into complex monomeric and polymeric tungstate (WO4) species in the environment; this led to increased solubility and mobility in soils and increased bioaccumulation potential in plant and animal tissues. Here we expand on the results of our previous research, which examined tungsten toxicity, bioaccumulation, and compartmentalization into organisms, and present in this research that the bioaccumulation of W was related to greater than 50% reduction in the mechanical properties of the snail (Otala lactea), based on depth-sensing nanoindentation. Synchrotron-based X-ray fluorescence maps and X-ray diffraction measurements confirm the integration of W in newly formed layers of the shell matrix with the observed changes in shell biomechanical properties, mineralogical composition, and crystal orientation. With further development, this technology could be employed as a biomonitoring tool for historic metals contamination since unlike the more heavily studied bioaccumulation into soft tissue, shell tissue does not actively eliminate contaminants.

AN - 1735335441; 26411301 AB - A rapid method for the synthesis of carbon-11 radiolabeled indole was developed using a sub-nanomolar quantity of no-carrier-added [(11)C]cyanide as radio-precursor. Based upon a reported synthesis of 2-(2-nitrophenyl)acetonitrile (), a highly reactive substrate 2-nitrobenzyl bromide () was evaluated for nucleophilic [(11)C]cyanation. Additionally, related reaction conditions were explored with the goal of obtaining of highly reactive 2-(2-nitrophenyl)-[1-(11)C]acetonitrile () while inhibiting its rapid conversion to 2,3-bis(2-nitrophenyl)-[1-(11)C]propanenitrile (). Next, a RANEY® Nickel catalyzed reductive cyclization method was utilized for synthesizing the desired [2-(11)C]indole with hydrazinium monoformate as the active reducing agent. Extensive and iterative screening of basicity, temperature and stoichiometry was required to overcome the large stoichiometry bias that favored 2-nitrobenzylbromide () over [(11)C]cyanide, which both caused further alkylation of the desired nitrile and poisoned the RANEY® Nickel catalyst. The result is an efficient two-step, streamlined method to reliably synthesize [2-(11)C]indole with an entire radiochemical yield of 21 ± 2.2% (n = 5, ranging from 18-24%). The radiochemical purity of the final product was >98% and specific activity was 176 ± 24.8 GBq μmol(-1) (n = 5, ranging from 141-204 GBq μmol(-1)). The total radiosynthesis time including product purification by semi-preparative HPLC was 50-55 min from end of cyclotron bombardment.

AN - 1747307104; 26545157 AB - The rational design and synthesis of narrow-gap colloidal semiconductor nanocrystals (NCs) is an important step toward the next generation of solution-processable photovoltaics, photodetectors, and thermoelectric devices. SnTe NCs are particularly attractive as a Pb-free alternative to NCs of narrow-gap lead chalcogenides. Previous synthetic efforts on SnTe NCs have focused on spherical nanoparticles. Here we report new strategies for synthesis of SnTe NCs with shapes tunable from highly monodisperse nanocubes, to nanorods (NRs) with variable aspect ratios, and finally to long, straight nanowires (NWs). Reaction at high temperature quickly forms thermodynamically favored nanocubes, but low temperatures lead to elongated particles. Transmission electron microscopy studies of reaction products at various stages of the synthesis reveal that the growth and shape-focusing of monodisperse SnTe nanocubes likely involves interparticle ripening, while directional growth of NRs and NWs may be initiated by particle dimerization via oriented attachment.

AN - 1746871791; 26639353 AB - Clostridium botulinum neurotoxin (BoNT) is released as a progenitor complex, in association with a non-toxic-non-hemagglutinin protein (NTNH) and other associated proteins. We have determined the crystal structure of M type Progenitor complex of botulinum neurotoxin E [PTC-E(M)], a heterodimer of BoNT and NTNH. The crystal structure reveals that the complex exists as a tight, interlocked heterodimer of BoNT and NTNH. The crystal structure explains the mechanism of molecular assembly of the complex and reveals several acidic clusters at the interface responsible for association at low acidic pH and disassociation at basic/neutral pH. The similarity of the general architecture between the PTC-E(M) and the previously determined PTC-A(M) strongly suggests that the progenitor M complexes of all botulinum serotypes may have similar molecular arrangement, although the neurotoxins apparently can take very different conformation when they are released from the M complex.

AN - 1738818479; 26580482 AB - Developing novel electrocatalysts for small molecule oxidation processes, including formic acid oxidation (FAOR), methanol oxidation reaction (MOR), and ethanol oxidation reaction (EOR), denoting the key anodic reactions for their respective fuel cell configurations, is a significant and relevant theme of recent efforts in the field. Herein, in this report, we demonstrated a concerted effort to couple and combine the benefits of small size, anisotropic morphology, and tunable chemical composition in order to devise a novel "family" of functional architectures. In particular, we have fabricated not only ultrathin 1-D Pd(1-x)Cu(x) alloys but also Pt-coated Pd(1-x)Cu(x) (i.e., Pt∼Pd(1-x)Cu(x); herein the ∼ indicates an intimate association, but not necessarily actual bond formation, between the inner bimetallic core and the Pt outer shell) core-shell hierarchical nanostructures with readily tunable chemical compositions by utilizing a facile, surfactant-based, wet chemical synthesis coupled with a Cu underpotential deposition technique. Our main finding is that our series of as-prepared nanowires are functionally flexible. More precisely, we demonstrate that various examples within this "family" of structural motifs can be tailored for exceptional activity with all 3 of these important electrocatalytic reactions. In particular, we note that our series of Pd(1-x)Cu(x) nanowires all exhibit enhanced FAOR activities as compared with not only analogous Pd ultrathin nanowires but also commercial Pt and Pd standards, with Pd9Cu representing the "optimal" composition. Moreover, our group of Pt∼Pd(1-x)Cu(x) nanowires consistently outperformed not only commercial Pt NPs but also ultrathin Pt nanowires by several fold orders of magnitude for both the MOR and EOR reactions in alkaline media. The variation of the MOR and EOR performance with the chemical composition of our ultrathin Pt∼Pd(1-x)Cu(x) nanowires was also discussed.

AN - 1840622138; 2016-098577 AB - While scientists have a good theoretical understanding of the heat capacity of both solids and gases, a general theory of the heat capacity of liquids has always remained elusive. Apart from being an awkward hole in our knowledge, heat capacity--the amount of heat needed to change a substance's temperature by a certain amount--is a relevant quantity that it would be nice to be able to predict. I will introduce a phonon-based approach to liquids and supercritical fluids to describe its thermodynamics in terms of sound propagation. I will show that the internal liquid energy has a transverse sound propagation gaps and explain their evolution with temperature variations on the P-T diagram. I will explain how this theoretical framework covers the Debye theory of solids, the phonon theory of liquids, and thermodynamic limits such as the Delong-Petit and the ideal gas thermodynamic limits. As a results, the experimental evidence for the new thermodynamic boundary in the supercritical state (the Frenkel line) on the P-T phase diagram will be demonstrated. Then, I will report on inelastic X-ray scattering experiments combined with the molecular dynamics simulations on deeply supercritical Ar. The presented results unveil the mechanism and regimes of sound propagation in the liquid matter and provide compelling evidence for the adiabatic-to-isothermal longitudinal sound propagation transition. As a result, a universal link will be demonstrated between the positive sound dispersion (PSD) phenomenon and the origin of transverse sound propagation revealing the viscous-to-elastic crossover in compressed liquids. Both can be considered as a universal fingerprint of the dynamic response of a liquid. They can be used then for a signal detection and analysis of a dynamic response in deep water and other fluids which is relevant for describing the thermodynamics of gas giants. The consequences of this finding will be discussed, including a physically justified way to demarcate the interior and the atmosphere in gas giants such as Jupiter and Saturn.

Nebular magnetic fields are thought to play a dominant role in global disk evolution by driving angular momentum transport via the magneto-rotational instability and/or magnetized disk winds, with the magnetically-driven accretion rate proportional to the square of the field strength. Previous paleomagnetic analyses of the Semarkona meteorite found evidence for a approximately 5-50 mu T solar nebular field at approximately 2-3 My after the formation of calcium-aluminum-rich inclusions (CAIs), which consist of the first solids condensed from the cooling protoplanetary disk. These field strengths are consistent with stellar accretion rates of approximately 10 (super -8) M (sub sun) /yr as typically observed for Sun-like stars. A key remaining question is the time when the nebular magnetic field and solar nebula itself dispersed. To address this, we analyzed the paleomagnetism of angrites, a class of exceptionally well-preserved igneous rocks that should retain magnetic records beginning just approximately 4 My after CAI formation. Here we present paleomagnetic, rock magnetic, and synchrotron-based transmission X-ray microscopic analyses of the quenched angrites D'Orbigny, Sahara 99555 and Asuka 881371. Our data show that the magnetic field at the angrite parent body region was < approximately 0.1 mu T at approximately 4 My after CAI formation. This indicates that the nebular magnetic field had rapidly declined by at least a factor of approximately 50 by that time, such that the magnetically driven solar accretion rate was well below 10-11 M (sub sun) /yr. Because a strong nebular magnetic field was likely present throughout most of the gaseous disk lifetime, our results suggest that the solar nebula itself had probably already dispersed by approximately 4 My after CAI formation. This dispersal time agrees with typical protoplanetary disk lifetimes inferred from infrared excesses for sun-like protostars. Our results suggest that the formation of the solar system giant planets, as well as the gas phase planetary migration, had largely completed by approximately 4 My after CAI formation. Furthermore, the formation of chondrules after this period would have not required substantial magnetic fields or nebular gas, thereby favoring planetesimal collision models over nebular shocks and magnetic reconnection.

Scanning transmission x-ray microscopy (STXM) analysis of the soil showed that Pu was present in its polymeric form and associated with Fe- and Mn- oxides and aluminosilicates. Uranium analysis by x-ray diffraction (mu -XRD) revealed discrete U-containing mineral phases, viz., schoepite, sharpite, and liebigite; synchrotron x-ray fluorescence (mu -XRF) mapping showed its association with Fe- and Ca-phases; and mu -x-ray absorption near edge structure (mu -XANES) confirmed U(IV) and U(VI) oxidation states. Addition of citric acid or glucose to the soil and incubated under aerobic or anaerobic conditions enhanced indigenous microbial activity and the dissolution of Pu. Detectable amount of Am and no U was observed in solution. In the citric acid-amended sample, Pu concentration increased with time and decreased to below detection levels when the citric acid was completely consumed. In contrast, with glucose amendment, Pu remained in solution. Pu speciation studies suggest that it exists in mixed oxidation states (III/IV) in a polymeric form as colloids. Although Pu(IV) is the most prevalent and generally considered to be more stable chemical form in the environment, our findings suggest that under the appropriate conditions, microbial activity could affect its solubility and long-term stability in contaminated environments.

Here, we explore reordering transitions in thin films of block-copolymer cylinder-forming polystyrene-block-poly(methyl methacrylate). We observe several transient states as films order towards horizontally-aligned cylinders. In particular, there is an early-stage reorganization from randomly-packed cylinders into hexagonally-packed vertically-aligned cylinders; followed by a reorientation transition from vertical to horizontal cylinder states. These transitions are thermally activated. The growth of horizontal grains within an otherwise vertical morphology proceeds anisotropically, resulting in anisotropic grains in the final horizontal state. The size, shape, and anisotropy of grains are influenced by ordering history; for instance, faster heating rates reduce grain anisotropy. These results help elucidate aspects of pathway-dependent ordering in block-copolymer thin films.

AN - 1735328695; 26459556 AB - UNLABELLEDBacterial pathogens Neisseria meningitidis and Brucella abortus pose threats to human and animal health worldwide, causing meningococcal disease and brucellosis, respectively. Mortality from acute N. meningitidis infections remains high despite antibiotics, and brucellosis presents alimentary and health consequences. Superoxide dismutases are master regulators of reactive oxygen and general pathogenicity factors and are therefore therapeutic targets. Cu,Zn superoxide dismutases (SODs) localized to the periplasm promote survival by detoxifying superoxide radicals generated by major host antimicrobial immune responses. We discovered that passive immunization with an antibody directed at N. meningitidis SOD (NmSOD) was protective in a mouse infection model. To define the relevant atomic details and solution assembly states of this important virulence factor, we report high-resolution and X-ray scattering analyses of NmSOD and of SOD from B. abortus (BaSOD). The NmSOD structures revealed an auxiliary tetrahedral Cu-binding site bridging the dimer interface; mutational analyses suggested that this metal site contributes to protein stability, with implications for bacterial defense mechanisms. Biochemical and structural analyses informed us about electrostatic substrate guidance, dimer assembly, and an exposed C-terminal epitope in the NmSOD dimer. In contrast, the monomeric BaSOD structure provided insights for extending immunogenic peptide epitopes derived from the protein. These collective results reveal unique contributions of SOD to pathogenic virulence, refine predictive motifs for distinguishing SOD classes, and suggest general targets for antibacterial immune responses. The identified functional contributions, motifs, and targets distinguishing bacterial and eukaryotic SOD assemblies presented here provide a foundation for efforts to develop SOD-specific inhibitors of or vaccines against these harmful pathogens.IMPORTANCEBy protecting microbes against reactive oxygen insults, SODs aid survival of many bacteria within their hosts. Despite the ubiquity and conservation of these key enzymes, notable species-specific differences relevant to pathogenesis remain undefined. To probe mechanisms that govern the functioning of Neisseria meningitidis and Brucella abortus SODs, we used X-ray structures, enzymology, modeling, and murine infection experiments. We identified virulence determinants common to the two homologs, assembly differences, and a unique metal reservoir within meningococcal SOD that stabilizes the enzyme and may provide a safeguard against copper toxicity. The insights reported here provide a rationale and a basis for SOD-specific drug design and an extension of immunogen design to target two important pathogens that continue to pose global health threats.

AN - 1736415257; 26389724 AB - For alkali-metal-ion batteries, probing the dynamic processes of ion transport in electrodes is critical to gain insights into understanding how the electrode functions and thus how we can improve it. Here, by using in situ high-resolution transmission electron microscopy, we probe the dynamics of Na transport in MoS2 nanostructures in real-time and compare the intercalation kinetics with previous lithium insertion. We find that Na intercalation follows the two-phase reaction mechanism, that is, trigonal prismatic 2H-MoS2 → octahedral 1T-NaMoS2, and the phase boundary is ∼2 nm thick. The velocity of the phase boundary at <10 nm/s is 1 order smaller than that of lithium diffusion, suggesting sluggish kinetics for sodium intercalation. The newly formed 1T-NaMoS2 contains a high density of defects and series superstructure domains with typical sizes of ∼3-5 nm. Our results provide valuable insights into finding suitable Na electrode materials and understanding the properties of transition metal dichalcogenide MoS2.

AN - 1731784357; 26522088 AB - The seven antigenically distinct serotypes (A-G) of botulinum neurotoxin (BoNT) are responsible for the deadly disease botulism. BoNT serotype A (BoNT/A) exerts its lethal action by cleaving the SNARE protein SNAP-25, leading to inhibition of neurotransmitter release, flaccid paralysis and autonomic dysfunction. BoNTs are dichain proteins consisting of a ∼ 100 kDa heavy chain and a ∼ 50 kDa light chain; the former is responsible for neurospecific binding, internalization and translocation, and the latter for cleavage of neuronal SNARE proteins. Because of their extreme toxicity and history of weaponization, the BoNTs are regarded as potential biowarfare/bioterrorism agents. No post-symptomatic therapeutic interventions are available for BoNT intoxication other than intensive care; therefore it is imperative to develop specific antidotes against this neurotoxin. To this end, a cyclic peptide inhibitor (CPI-1) was evaluated in a FRET assay for its ability to inhibit BoNT/A light chain (Balc). CPI was found to be highly potent, exhibiting a Ki of 12.3 nM with full-length Balc448 and 39.2 nM using a truncated crystallizable form of the light chain (Balc424). Cocrystallization studies revealed that in the Balc424-CPI-1 complex, the inhibitor adopts a helical conformation, occupies a high percentage of the active site cavity and interacts in an amphipathic manner with critical active site residues. The data suggest that CPI-1 prevents SNAP-25 from accessing the Balc active site by blocking both the substrate binding path at the surface and the Zn(2+) binding region involved in catalysis. This differs from linear peptide inhibitors described to date which block only the latter.

AN - 1733192828; 26342082 AB - Aspergillus fumigatus is the most virulent species within the Aspergillus genus and causes invasive infections with high mortality rates. The exopolysaccharide galactosaminogalactan (GAG) contributes to the virulence of A. fumigatus. A co-regulated five-gene cluster has been identified and proposed to encode the proteins required for GAG biosynthesis. One of these genes, sph3, is predicted to encode a protein belonging to the spherulin 4 family, a protein family with no known function. Construction of an sph3-deficient mutant demonstrated that the gene is necessary for GAG production. To determine the role of Sph3 in GAG biosynthesis, we determined the structure of Aspergillus clavatus Sph3 to 1.25 Å. The structure revealed a (β/α)8 fold, with similarities to glycoside hydrolase families 18, 27, and 84. Recombinant Sph3 displayed hydrolytic activity against both purified and cell wall-associated GAG. Structural and sequence alignments identified three conserved acidic residues, Asp-166, Glu-167, and Glu-222, that are located within the putative active site groove. In vitro and in vivo mutagenesis analysis demonstrated that all three residues are important for activity. Variants of Asp-166 yielded the greatest decrease in activity suggesting a role in catalysis. This work shows that Sph3 is a glycoside hydrolase essential for GAG production and defines a new glycoside hydrolase family, GH135.

AN - 1732596210; 26467312 AB - Self-organization of fluorescent nanoparticles, using biological molecules such as phospholipids to control assembly distances, is a promising method for creating hybrid nanostructures. We report here the formation of hybrid condensed phases made of anisotropic nanoparticles and phospholipids. Such structure formation is driven by electrostatic interaction between the nanoparticles and the phospholipids, and results in the formation of a 2D rectangular liquid crystal, as confirmed by high-resolution Small-Angle X-ray Scattering (SAXS). Moreover, we show that the fluorescent properties of the NPs are not modified by the self-assembly process.

AN - 1727994797; 26257399 AB - C. elegans MnSOD-3 has been implicated in the longevity pathway and its mechanism of catalysis is relevant to the aging process and carcinogenesis. The structures of MnSOD-3 provide unique crystallographic evidence of a dynamic region of the tetrameric interface (residues 41-54). We have determined the structure of the MnSOD-3-azide complex to 1.77-Å resolution. Analysis of this complex shows that the substrate analog, azide, binds end-on to the manganese center as a sixth ligand and that it ligates directly to a third and new solvent molecule also positioned within interacting distance to the His30 and Tyr34 residues of the substrate access funnel. This is the first structure of a eukaryotic MnSOD-azide complex that demonstrates the extended, uninterrupted hydrogen-bonded network that forms a proton relay incorporating three outer sphere solvent molecules, the substrate analog, the gateway residues, Gln142, and the solvent ligand. This configuration supports the formation and release of the hydrogen peroxide product in agreement with the 5-6-5 catalytic mechanism for MnSOD. The high product dissociation constant k4 of MnSOD-3 reflects low product inhibition making this enzyme efficient even at high levels of superoxide.

AN - 1721917825; 26208874 AB - Methamphetamine's widepread abuse and concerns that it might increase Parkinson's disease led us to assess if the reported loss of dopamine transporters (DAT) in methamphetamine abusers (MA) reflected damage to dopamine neurons. Using PET with [(11)C]cocaine to measure DAT, and with [(11)C]raclopride to measure dopamine release (assessed as changes in specific binding of [(11)C]raclopride between placebo and methylphenidate), which was used as a marker of dopamine neuronal function, we show that MA (n=16), tested during early detoxification, had lower DAT (20-30%) but overall normal DA release in striatum (except for a small decrease in left putamen), when compared to controls (n=15). In controls, DAT were positively correlated with DA release (higher DAT associated with larger DA increases), consistent with DAT serving as markers of DA terminals. In contrast, MA showed a trend for a negative correlation (p=0.07) (higher DAT associated with lower DA increases), consistent with reduced DA re-uptake following DAT downregulation. MA who remained abstinent nine-months later (n=9) showed significant increases in DAT (20%) but methylphenidate-induced dopamine increases did not change. In contrast, in controls, DAT did not change when retested 9 months later but methylphenidate-induced dopamine increases in ventral striatum were reduced (p=0.05). Baseline D2/D3 receptors in caudate were lower in MA than in controls and did not change with detoxification, nor did they change in the controls upon retest. The loss of DAT in the MA, which was not associated with a concomitant reduction in dopamine release as would have been expected if DAT loss reflected DA terminal degneration; as well as the recovery of DAT after protracted detoxification, which was not associated with increased dopamine release as would have been expected if DAT increases reflected terminal regeneration, indicate that the loss of DAT in these MA does not reflect degeneration of dopamine terminals.

AN - 1728675321; 26378240 AB - Lignin, a rigid biopolymer in plant cell walls, is derived from the oxidative polymerization of three monolignols. The composition of monolignol monomers dictates the degree of lignin condensation, reactivity, and thus the degradability of plant cell walls. Guaiacyl lignin is regarded as the condensed structural unit. Polymerization of lignin is initiated through the deprotonation of the para-hydroxyl group of monolignols. Therefore, preferentially modifying the para-hydroxyl of a specific monolignol to deprive its dehydrogenation propensity would disturb the formation of particular lignin subunits. Here, we test the hypothesis that specific remodeling the active site of a monolignol 4-O-methyltransferase would create an enzyme that specifically methylates the condensed guaiacyl lignin precursor coniferyl alcohol. Combining crystal structural information with combinatorial active site saturation mutagenesis and starting with the engineered promiscuous enzyme, MOMT5 (T133L/E165I/F175I/F166W/H169F), we incrementally remodeled its substrate binding pocket by the addition of four substitutions, i.e. M26H, S30R, V33S, and T319M, yielding a mutant enzyme capable of discriminately etherifying the para-hydroxyl of coniferyl alcohol even in the presence of excess sinapyl alcohol. The engineered enzyme variant has a substantially reduced substrate binding pocket that imposes a clear steric hindrance thereby excluding bulkier lignin precursors. The resulting enzyme variant represents an excellent candidate for modulating lignin composition and/or structure in planta.

AN - 1719420354; 26358292 AB - Mutations in rhodopsin can cause misfolding and aggregation of the receptor, which leads to retinitis pigmentosa, a progressive retinal degenerative disease. The structure adopted by misfolded opsin mutants and the associated cell toxicity is poorly understood. Förster resonance energy transfer (FRET) and Fourier transform infrared (FTIR) microspectroscopy were utilized to probe within cells the structures formed by G188R and P23H opsins, which are misfolding mutants that cause autosomal dominant retinitis pigmentosa. Both mutants formed aggregates in the endoplasmic reticulum and exhibited altered secondary structure with elevated β-sheet and reduced α-helical content. The newly formed β-sheet structure may facilitate the aggregation of misfolded opsin mutants. The effects observed for the mutants were unrelated to retention of opsin molecules in the endoplasmic reticulum itself.

The catalyst is produced by heating an earth-abundant and low-cost mixture of ammonium tungstate, soybean powder and graphene nanoplatelets (WSoyGnP). The catalyst compound consists of tungsten carbide (W sub(2)C and WC) and tungsten nitride (WN) nanoparticles decorated on graphene nanoplatelets. The catalyst demonstrates an overpotential ( eta sub(10), the potential at a current density of 10 mA cm super(-2)) of 0.105 V, which is the smallest among tungsten-based HER catalysts in acidic media. The coupling with graphene significantly reduces the charge transfer resistance and increases the active surface area of the product, which are favorable for enhancing the HER activity. Therefore, the approach of employing biomass and other less expensive materials as precursors for the production of catalysts with high HER activity provides a new path for the design and development of efficient catalysts for the hydrogen production industry.

AN - 1708897149; 26275678 AB - Botulinum neurotoxins (BoNTs) are among the most potent biological toxin known to humans, and are classified as Category A bioterrorism agents by the Centers for Disease Control and prevention (CDC). There are seven known BoNT serotypes (A-G) which have been thus far identified in literature. BoNTs have been shown to block neurotransmitter release by cleaving proteins of the soluble NSF attachment protein receptor (SNARE) complex. Disruption of the SNARE complex precludes motor neuron failure which ultimately results in flaccid paralysis in humans and animals. Currently, there are no effective therapeutic treatments against the neurotoxin light chain (LC) after translocation into the cytosols of motor neurons. In this work, high-throughput in silico screening was employed to screen a library of commercially available compounds from ZINC database against BoNT/A-LC. Among the hit compounds from the in silico screening, two lead compounds were identified and found to have potent inhibitory activity against BoNT/A-LC in vitro, as well as in Neuro-2a cells. A few analogs of the lead compounds were synthesized and their potency examined. One of these analogs showed an enhanced activity than the lead compounds.

The analysis was performed in the context of a U.S. Department of Energy effort to develop a compendium of informative nuclear fuel cycle performance data. The objective of this paper is to determine whether intermediate spectrum systems, having a majority of fission events occurring with incident neutron energies between 1 eV and 10 super(5) eV, perform as well as fast spectrum systems in this fuel cycle. The intermediate spectrum options analyzed include tight lattice heavy or light water-cooled reactors, continuously refueled molten salt reactors, and a sodium-cooled reactor with hydride fuel. All options were modeled in reactor physics codes to calculate their lattice physics, spectrum characteristics, and fuel compositions over time. Based on these results, detailed metrics were calculated to compare the fuel cycle performance. These metrics include waste management and resource utilization, and are binned to accommodate uncertainties. The performance of the intermediate systems for this self-sustaining thorium fuel cycle was similar to a representative fast spectrum system. However, the number of fission neutrons emitted per neutron absorbed limits performance in intermediate spectrum systems.

Using in situ energy dispersive X-ray diffraction (EDXRD) of an intact battery, the location and distribution of silver metal nanoparticles generated upon reduction-displacement deposition within an Ag sub(2)VP sub(2)O sub(8) cathode containing a pre-existing percolation network can be observed for the first time. This study yielded unexpected results where higher rate initial discharge generated a more effective conductive matrix. This stands in contrast to cells with cathodes with no conductive additive where a low rate initial discharge proved more effective. These results provide evidence that using conductive additives in conjunction with an in situ reduction-displacement deposition of silver metal provides a path toward the ultimate goal of complete electrical contact and full utilization of all electroactive particles.

AN - 1701297783; 26232259 AB - Lifetime exposure to high concentrations of hexavalent chromium [Cr(VI)] in drinking water results in intestinal damage and an increase in duodenal tumors in B6C3F1 mice. To assess whether these tumors could be the result of a direct mutagenic or genotoxic mode of action, we conducted a GLP-compliant 7-day drinking water study to assess crypt health along the entire length of the duodenum. Mice were exposed to water (vehicle control), 1.4, 21, or 180 ppm Cr(VI) via drinking water for 7 consecutive days. Crypt enterocytes in Swiss roll sections were scored as normal, mitotic, apoptotic, karyorrhectic, or as having micronuclei. A single oral gavage of 50mg/kg cyclophosphamide served as a positive control for micronucleus induction. Exposure to 21 and 180 ppm Cr(VI) significantly increased the number of crypt enterocytes. Micronuclei and γ-H2AX immunostaining were not elevated in the crypts of Cr(VI)-treated mice. In contrast, treatment with cyclophosphamide significantly increased numbers of crypt micronuclei and qualitatively increased γ-H2AX immunostaining. Synchrotron-based X-ray fluorescence (XRF) microscopy revealed the presence of strong Cr fluorescence in duodenal villi, but negligible Cr fluorescence in the crypt compartment. Together, these data indicate that Cr(VI) does not adversely effect the crypt compartment where intestinal stem cells reside, and provide additional evidence that the mode of action for Cr(VI)-induced intestinal cancer in B6C3F1 mice involves chronic villous wounding resulting in compensatory crypt enterocyte hyperplasia.

AN - 1698960586; 26168344 AB - Nanowire growth by the vapour-liquid-solid (VLS) process enables a high level of control over nanowire composition, diameter, growth direction, branching and kinking, periodic twinning, and crystal structure. The tremendous impact of VLS-grown nanowires is due to this structural versatility, generating applications ranging from solid-state lighting and single-photon sources to thermoelectric devices. Here, we show that the morphology of these nanostructures can be further tailored by using the liquid droplets that catalyse nanowire growth as a 'mixing bowl', in which growth materials are sequentially supplied to nucleate new phases. Growing within the liquid, these phases adopt the shape of faceted nanocrystals that are then incorporated into the nanowires by further growth. We demonstrate this concept by epitaxially incorporating metal-silicide nanocrystals into Si nanowires with defect-free interfaces, and discuss how this process can be generalized to create complex nanowire-based heterostructures.

Excellent concordance with the experimental results shows that the structure of the nanoparticles can be controlled at subnanometer resolution simply by changing the reactant concentration. The results of this study not only offer a better understanding of the complex mechanisms governing reactions in microemulsions, but open up a simple new way to synthesize bimetallic nanoparticles with ad hoc controlled nanostructures.

Uranium dioxide (UO[sub 2]) fuels with various advanced cladding materials were analyzed to provide a reference for cladding performance impacts. This paper also includes evaluation of UN-U[sub 3]Si[sub 5] fuels with Kanthal AF or APMT cladding. The objective of the U[sub 3]Si[sub 5] phase in the UN-U[sub 3]Si[sub 5] fuel concept is to shield the nitride phase from water. Analysis of the rim effect due to self-shielding in the fuel shows that the UN-based ceramic fuels are not expected to have significantly different relative bum-up distributions at discharge relative to the UO[sub 2] reference fuel. It is recognized that the fuel and cladding properties assumed in these assessments are preliminary, and that additional data are necessary for these materials, most significantly under irradiation.

AN - 1691013814; 26100566 AB - Self-assembly of block copolymers is a powerful motif for spontaneously forming well-defined nanostructures over macroscopic areas. Yet, the inherent energy minimization criteria of self-assembly give rise to a limited library of structures; diblock copolymers naturally form spheres on a cubic lattice, hexagonally packed cylinders and alternating lamellae. Here, we demonstrate multicomponent nanomeshes with any desired lattice symmetry. We exploit photothermal annealing to rapidly order and align block copolymer phases over macroscopic areas, combined with conversion of the self-assembled organic phase into inorganic replicas. Repeated photothermal processing independently aligns successive layers, providing full control of the size, symmetry and composition of the nanoscale unit cell. We construct a variety of symmetries, most of which are not natively formed by block copolymers, including squares, rhombuses, rectangles and triangles. In fact, we demonstrate all possible two-dimensional Bravais lattices. Finally, we elucidate the influence of nanostructure on the electrical and optical properties of nanomeshes.

Separation of parameterization biases single-column model CAM5 simulations of shallow cumulus AN - 1701503307; PQ0001794583 AB - Climatically important low-level clouds are commonly misrepresented in climate models. The FAst-physics System TEstbed and Research (FASTER) Project has constructed case studies from the Atmospheric Radiation Measurement Climate Research Facility's Southern Great Plain site during the RACORO aircraft campaign to facilitate research on model representation of boundary-layer clouds. This paper focuses on using the single-column Community Atmosphere Model version 5 (SCAM5) simulations of a multi-day continental shallow cumulus case to identify specific parameterization causes of low-cloud biases. Consistent model biases among the simulations driven by a set of alternative forcings suggest that uncertainty in the forcing plays only a relatively minor role. In-depth analysis reveals that the model's shallow cumulus convection scheme tends to significantly under-produce clouds during the times when shallow cumuli exist in the observations, while the deep convective and stratiform cloud schemes significantly over-produce low-level clouds throughout the day. The links between model biases and the underlying assumptions of the shallow cumulus scheme are further diagnosed with the aid of large-eddy simulations and aircraft measurements, and by suppressing the triggering of the deep convection scheme. It is found that the weak boundary layer turbulence simulated is directly responsible for the weak cumulus activity and the simulated boundary layer stratiform clouds. Increased vertical and temporal resolutions are shown to lead to stronger boundary layer turbulence and reduction of low-cloud biases.

Case study development and ensemble large-scale forcings AN - 1701492555; PQ0001794580 AB - Observation-based modeling case studies of continental boundary layer clouds have been developed to study cloudy boundary layers, aerosol influences upon them, and their representation in cloud- and global-scale models. Three 60 h case study periods span the temporal evolution of cumulus, stratiform, and drizzling boundary layer cloud systems, representing mixed and transitional states rather than idealized or canonical cases. Based on in situ measurements from the Routine AAF (Atmospheric Radiation Measurement (ARM) Aerial Facility) CLOWD (Clouds with Low Optical Water Depth) Optical Radiative Observations (RACORO) field campaign and remote sensing observations, the cases are designed with a modular configuration to simplify use in large-eddy simulations (LES) and single-column models. Aircraft measurements of aerosol number size distribution are fit to lognormal functions for concise representation in models. Values of the aerosol hygroscopicity parameter, Kappa , are derived from observations to be ~0.10, which are lower than the 0.3 typical over continents and suggestive of a large aerosol organic fraction. Ensemble large-scale forcing data sets are derived from the ARM variational analysis, European Centre for Medium-Range Weather Forecasts, and a multiscale data assimilation system. The forcings are assessed through comparison of measured bulk atmospheric and cloud properties to those computed in "trial" large-eddy simulations, where more efficient run times are enabled through modest reductions in grid resolution and domain size compared to the full-sized LES grid. Simulations capture many of the general features observed, but the state-of-the-art forcings were limited at representing details of cloud onset, and tight gradients and high-resolution transients of importance.

Large-eddy simulations of cumulus clouds and evaluation with in situ and ground-based observations AN - 1701486075; PQ0001794572 AB - A 60h case study of continental boundary layer cumulus clouds is examined using two large-eddy simulation (LES) models. The case is based on observations obtained during the RACORO Campaign (Routine Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) Clouds with Low Optical Water Depths (CLOWD) Optical Radiative Observations) at the ARM Climate Research Facility's Southern Great Plains site. The LES models are driven by continuous large-scale and surface forcings and are constrained by multimodal and temporally varying aerosol number size distribution profiles derived from aircraft observations. We compare simulated cloud macrophysical and microphysical properties with ground-based remote sensing and aircraft observations. The LES simulations capture the observed transitions of the evolving cumulus-topped boundary layers during the three daytime periods and generally reproduce variations of droplet number concentration with liquid water content (LWC), corresponding to the gradient between the cloud centers and cloud edges at given heights. The observed LWC values fall within the range of simulated values; the observed droplet number concentrations are commonly higher than simulated, but differences remain on par with potential estimation errors in the aircraft measurements. Sensitivity studies examine the influences of bin microphysics versus bulk microphysics, aerosol advection, supersaturation treatment, and aerosol hygroscopicity. Simulated macrophysical cloud properties are found to be insensitive in this nonprecipitating case, but microphysical properties are especially sensitive to bulk microphysics supersaturation treatment and aerosol hygroscopicity. Key Points * LES captures macro/microphysical variations under varying forcing and aerosol * Model results sensitive to measured aerosol size spectrum and hygroscopicity * Intermodel microphysics differences caused by the supersaturation treatments JF - Journal of Geophysical Research: Atmospheres AU - Endo, Satoshi AU - Fridlind, Ann M AU - Lin, Wuyin AU - Vogelmann, Andrew M AU - Toto, Tami AU - Ackerman, Andrew S AU - McFarquhar, Greg M AU - Jackson, Robert C AU - Jonsson, Haflidi H AU - Liu, Yangang AD - Brookhaven National Laboratory, Upton, New York, USA.

AN - 1667344898; 25703901 AB - The biological effect of ionic liquids (ILs) is one of the highly debated topics as they are being contemplated for various industrial applications. 1-ethyl-3-methylimidazolium acetate ([EMIM][Ac]) showed remarkable hormesis on anaerobic Clostridium sp. and aerobic Pseudomonas putida. Bacterial growth was stimulated at up to 2.5 g L(-1) and inhibited at >2.5 g L(-1) of [EMIM][Ac]. The growth of Clostridium sp. and P. putida were higher by 0.4 and 4-fold respectively, in the presence of 0.5 g L(-1) [EMIM][Ac]. Assessment of the effect of [EMIM][Ac] under different growth conditions showed that the hormesis of [EMIM][Ac] was mediated via regulation of medium pH. Hormetic effect of [EMIM][Ac] was evident only in medium with poor buffering capacity and in the presence of a fermentable substrate as the carbon source. The hormetic effect of [EMIM][Ac] on bacterial growth is most likely associated with the buffering capacity of acetate anion. These observations have implications in ILs toxicity studies and ecological risk assessment.

AN - 1680956976; 25923720 AB - It has been observed that wurtzite II-VI semiconducting nanobelts transform into single-crystal, periodically branched nanostructures upon heating. The mechanism of this novel transformation has been elucidated by heating II-VI nanobelts in an environmental transmission electron microscope (ETEM) in oxidizing, reducing, and inert atmospheres while observing their structural changes with high spatial resolution. The interplay of surface reconstruction of high-energy surfaces of the wurtzite phase and environment-dependent anisotropic chemical etching of certain crystal surfaces in the branching mechanism of nanobelts has been observed. Understanding of structural and chemical transformations of materials via in situ microscopy techniques and their role in designing new nanostructured materials is discussed.

AN - 1669839598; 25679799 AB - The persistence of polychlorinated biphenyl (PCB) Aroclor 1248 in soils and sediments is a major concern because of its toxicity and presence at high concentrations. In this study, we developed an integrated remediation system for PCBs using chemical catalysis and biodegradation. The dechlorination of Aroclor 1248 was achieved by treatment with bimetallic nanoparticles Pd/nFe under anoxic conditions. Among the 32 PCB congeners of Aroclor 1248 examined, our process dechlorinated 99%, 92%, 84%, and 28% of tri-, tetra-, penta-, and hexachlorinated biphenyls, respectively. The resulting biphenyl was biodegraded rapidly by Burkholderia xenovorans LB400. Benzoic acid was detected as an intermediate during the biodegradation process. The toxicity of the residual PCBs after nano-bio treatment was evaluated in terms of toxic equivalent values which decreased from 33.8×10(-5)μgg(-1) to 9.5×10(-5)μgg(-1). The residual PCBs also had low cytotoxicity toward Escherichia coli as demonstrated by lower reactive oxygen species levels, lower glutathione peroxidase activity, and a reduced number of dead bacteria.

Tabletop Nd:YAG lasers with up to several Joules of energy are mainly used to create ablation plasmas for stable operations. The obtained charge states depend on laser power density and target species. Two types of ion extraction schemes, direct plasma injection scheme (DPIS) and conventional static extraction, are used depending on the application. We optimized and selected a suitable laser irradiation condition and a beam extraction scheme to meet the requirement of the following accelerator system. We have demonstrated to accelerate more than 5 10 super(10) of C super(6+) ions using the DPIS. We successfully commissioned a low-charge ion beam provider to the user facilities in BNL. To achieve higher current, higher charge state and lower emittance, further studies will continue.

The process entails the conversion of multifunctional oxygenates generated from biomass pyrolysis over a metal oxide catalyst into ketonic-rich monofunctional molecules suitable for making hydrocarbon fuel components for gasoline, diesel, and jet fuel. A number of catalysts were explored, for example, anatase TiO sub(2) nanorods, CeO sub(x)-TiO sub(2) mixed oxides, pure CeO sub(2), ZrO sub(2), and MgO. Under pyrolysis conditions, ceria-based catalysts were effective in the conversion of hydroxy-carbonyls, anhydrosugars, and carboxylic acids into acetone, 2-butanone, pentanones, C6/C7 ketones, cyclopentanone, and 2-cyclopentenones. The highest carbon yield (23.5%) of ketonic precursors was achieved on the pure CeO sub(2).

We show that maskelynite of shock class 2 is structurally more similar to fused glass than to crystalline plagioclase. However, there are slight but significant differences-preservation of original preimpact igneous zoning, anisotropy at infrared wavelengths, X-ray anisotropy, and preservation of some intermediate range order-which are all consistent with a solid-state transformation from plagioclase to maskelynite.

Upon heating, the electrochemically delithiated LMO changed into Mn sub(3)O sub(4) phase at around 250 [degrees]C. Formation of MnO with rock-salt structure started at 520 [degrees]C. This observation is in contrast to the previous report for chemically delithiated LMO in air, in which a process of [lambda]-MnO sub(2) transforming to [beta]-MnO sub(2) was observed. Oxygen peak was not observed in all cases, presumably as a result of either consumption by the carbon or detection limit. CO sub(2) profile correlates well with the phase transition and indirectly suggests the oxygen release of the cathode. Introducing NCM into LMO has two effects: first, it makes the high temperature rock-salt phase formation more complicated with more peaks in CO sub(2) profile due to different MO (M = Ni, Mn, Co) phases; secondly, the onset temperature of CO sub(2) release is lowered, implying lowered oxygen release temperature. Upon heating, XRD patterns indicate the NCM part reacts first, followed by the LMO part. This confirms the better thermal stability of LMO over NCM.

AN - 1654700820; 25564871 AB - A quantitative description of recombination processes in nanostructured semiconductor photocatalysts-one that distinguishes between bulk (charge transport) and surface (chemical reaction) losses-is critical for advancing solar-to-fuel technologies. Here we present an in situ experimental framework that determines the bias-dependent quantum yield for ultrafast carrier transport to the reactive interface. This is achieved by simultaneously measuring the electrical characteristics and the subpicosecond charge dynamics of a heterostructured photoanode in a working photoelectrochemical cell. Together with direct measurements of the overall incident-photon-to-current efficiency, we illustrate how subtle structural modifications that are not perceivable by conventional X-ray diffraction can drastically affect the overall photocatalytic quantum yield. We reveal how charge carrier recombination losses occurring on ultrafast time scales can limit the overall efficiency even in nanostructures with dimensions smaller than the minority carrier diffusion length. This is particularly true for materials with high carrier concentration, where losses as high as 37% are observed. Our methodology provides a means of evaluating the efficacy of multifunctional designs where high overall efficiency is achieved by maximizing surface transport yield to near unity and utilizing surface layers with enhanced activity.

The complexity and accuracy of these models are suitable for evaluating the transient impact on bulk power systems. Of particular interest is the grid inertial response in such situations as different penetration levels of solar generation and fast cloud transient induced solar generation decrease coupled with outages that recurrently occur in the grid, e.g., a generator trip. The impact of such events on the grid frequency responses is investigated using a simplified simulation approach to account for the locational or spatial irradiance variation patterns and cloud movements. Responsive battery energy storage systems are recognized as an effective means to improve the inertial response.

In an attempt to determine under what conditions the solubilities of Cu, Fe, and Zn are maximized in MVPs, we performed experiments in the MVP-intermediate solid solution-pyrrhotite-quartz+ or -bornite system at 500-700 degrees C, 100 MPa and at an oxygen fugacity buffered by Ni-NiO. The MVP was composed initially of NaCl+KCl+HCl+H (sub 2) O, with a starting total salinity of 5 wt.% NaCl (equivalent) and HCl set to <2000 mu g/g. Experiments were performed with a supercritical fluid (500 and 600 degrees C) and in the vapor+brine region of immiscibility (700 degrees C). Fluid inclusions were trapped in quartz after equilibrating with Cu-Fe sulfides and a gold metal capsule. Synthetic fluid inclusions were analyzed by synchrotron x-ray microprobe at GSECARS of the Advanced Photon Source at Argonne National Laboratory. Fe, Cu, and Zn concentrations in the supercritical fluid at 500 degrees C were found to be approximately 1500 mu g/g, 350 mu g/g and 250 mu g/g, respectively. The concentrations of Fe, Cu, and Zn in the supercritical fluid at 600 degrees C were approximately 10,000 mu g/g, 800 mu g/g, and 350 mu g/g, respectively. Fe and Zn concentrations in the vapor at 700 degrees C were approximately 5000 mu g/g and approximately 350 mu g/g, respectively, and did not vary with sulfur fugacity. Cu concentrations in the vapor at 700 degrees C increased from approximately 300 mu g/g to approximately 2500 mu g/g with increasing sulfur fugacity, but never surpassed the concentration of Cu in the brine ( approximately 7000 mu g/g). Fe, Cu, and Zn are always higher in the brine ( approximately 30000, 7000, and 2000 mu g/g, respectively) than coexisting vapor or low salinity supercritical fluid illustrating these metals strong affinities for chloride. We hypothesize that Cu, Fe and Zn will complex predominantly with chloride and partition preferentially in the brine whereas Cu can also complex with reduced sulfur species, such as HS-, and may be substantially enhanced in a vapor or low salinity supercritical fluid in addition to brine. Thus, Cu can be effectively transported in both low- and high- salinity fluids enriched with reduced sulfur species in select subsolidus, hydrothermal systems.

While the origin of life itself remains one of the most significant scientific questions to be solved, any plausible scenario requires sufficient concentrations of phosphate ions to allow for the formation of phosphate-containing molecular building blocks that would eventually lead to life. Assuming that life originated in an aqueous environment, any scenario has to overcome the low total inorganic phosphate concentration (PO (sub 4) ) imposed by the low solubility of hydroxyapatite, which is referred to as the "phosphate problem". We used detailed, quantitative water-rock interaction modeling to explore the constraints on phosphate concentration on the early Earth. Building on earlier work, we calculated the composition of water interacting with komatiite-a proxy for a primitive crust-as a function of the partial pressure of CO (sub 2) (P (sub CO2) ) at a temperature of 75 degrees C. The resulting fluid (essentially primitive seawater) was then subjected to a maximum of ten evaporation cycles. Using present-day P (sub CO2) as a constraint, the primitive seawater and the brine after ten cycles of evaporation has a molar PO (sub 4) /Ca ratio that is smaller than unity (PO (sub 4) /Ca=0.3 in final brine). Elevating P (sub CO2) to twice the present-day levels pushes the primitive seawater and its brine across a chemical divide that leads to a molar PO (sub 4) /Ca ratio that is larger than unity (PO (sub 4) /Ca=8.2 in final brine). While the modest increase in P (sub CO2) leads to PO (sub 4) /Ca>1, the total PO (sub 4) concentration in the final brine was less than 4 10 (super -4) M. Further increasing P (sub CO2) to tenfold the present-day level leads to PO (sub 4) concentration in the final brine in the mM range, which is within biologically relevant values. With P (sub CO2) at 1 atm, the PO (sub 4) concentration in the final brine reaches 59 mM. Further increasing P (sub CO2) has no effect. In summary, this study shows for the first time that it is possible to overcome the "phosphate problem" by constraining P (sub CO2) -levels on the early Earth up to approximately 1 atm or higher. Independent published estimates of the atmospheric composition of the early earth suggest P (sub CO2) levels well above 1 atm, supporting the notion that primitive seawater and its brines could have had phosphate concentrations that are biologically relevant.

Use of crystalline garnets as waste forms to immobilize actinide radionuclides from nuclear wastes appears to be advantageous. Previous studies show that large loadings of uranium (U), and its analogues such as cerium (Ce) and thorium (Th) can be incorporated in garnet host phases, which have good aqueous durability at natural conditions. In this study, we synthesized a series of U-bearing garnet phases, Ca (sub 3) U (sub x) Zr (sub 2-x) Fe (sub 3) O (sub 12) (x=0.5-0.7), as well as the Ca (sub 3) (Zr (sub 2) )SiFe (super 3+) (sub 2) O (sub 12) end-member for comparison. The oxidation states of U in these phases were examined by X-ray photoelectron spectroscopy and X-ray absorption spectroscopy. U was found in mixed pentavalent and hexavalent oxidation states in the phases with x=0.6 and 0.7. The oxidation state and coordination environment of Fe were investigated by (super 57) Fe-Mossbauer spectroscopy. Our results show that all the Fe cations in the U-substituted garnets are tetrahedrally coordinated Fe (super 3+) but in two different local environments. The enthalpies of formation of garnets from constituent oxides and elements were determined by high temperature oxide melt solution calorimetry. The thermodynamic analyses demonstrate that these substituted garnets can be stabilized under reducing conditions. Structural and thermodynamic analysis further provides explanations for the formation and stabilization of the natural uranium garnet elbrusite-(Zr), and supports the potential use of Ca (sub 3) UxZr (sub 2-x) Fe (sub 3) O (sub 12) phases as viable waste forms for U and other actinides.

Analysing these data, the monthly mean values of tau (0.50 mu m) and alpha and the relative frequency histograms of the daily mean values of both parameters were determined for winter-spring and summer-autumn in the Arctic and for austral summer in Antarctica. The Arctic and Antarctic covariance plots of the seasonal median values of alpha versus tau (0.50 mu m) showed: (i) a considerable increase in tau (0.50 mu m) for the Arctic aerosol from summer to winter-spring, without marked changes in alpha ; and (ii) a marked increase in tau (0.50 mu m) passing from the Antarctic Plateau to coastal sites, whereas alpha decreased considerably due to the larger fraction of sea-salt aerosol. Good agreement was found when comparing ground-based sun-photometer measurements of tau (lambda ) and alpha at Arctic and Antarctic coastal sites with Microtops measurements conducted during numerous AERONET/MAN cruises from 2006 to 2013 in three Arctic Ocean sectors and in coastal and off-shore regions of the Southern Atlantic, Pacific, and Indian Oceans, and the Antarctic Peninsula. Lidar measurements were also examined to characterise vertical profiles of the aerosol backscattering coefficient measured throughout the year at Ny-Alesund. Satellite-based MODIS, MISR, and AATSR retrievals of tau (lambda ) over large parts of the oceanic polar regions during spring and summer were in close agreement with ship-borne and coastal ground-based sun-photometer measurements. An overview of the chemical composition of mode particles is also presented, based on in-situ measurements at Arctic and Antarctic sites. Fourteen log-normal aerosol number size-distributions were defined to represent the average features of nuclei, accumulation and coarse mode particles for Arctic haze, summer background aerosol, Asian dust and boreal forest fire smoke, and for various background austral summer aerosol types at coastal and high-altitude Antarctic sites. The main columnar aerosol optical characteristics were determined for all 14 particle modes, based on in-situ measurements of the scattering and absorption coefficients. Diurnally averaged direct aerosol-induced radiative forcing and efficiency were calculated for a set of multimodal aerosol extinction models, using various Bidirectional Reflectance Distribution Function models over vegetation-covered, oceanic and snow-covered surfaces. These gave a reliable measure of the pronounced effects of aerosols on the radiation balance of the surface-atmosphere system over polar regions. Abstract Copyright (2015) Elsevier, B.V.

AN - 1652396135; 25607953 AB - Growth in sucrose medium was previously found to trigger the expression of functions involved in the plant associated life style of the endophytic bacterium Enterobacter sp. 638. Therefore, comparative transcriptome analysis between cultures grown in sucrose or lactate medium was used to gain insights in the expression levels of bacterial functions involved in the endophytic life style of strain 638. Growth on sucrose as a carbon source resulted in major changes in cell physiology, including a shift from a planktonic life style to the formation of bacterial aggregates. This shift was accompanied by a decrease in transcription of genes involved in motility (e.g., flagella biosynthesis) and an increase in the transcription of genes involved in colonization, adhesion and biofilm formation. The transcription levels of functions previously suggested as being involved in endophytic behavior and functions responsible for plant growth promoting properties, including the synthesis of indole-acetic acid, acetoin and 2,3-butanediol, also increased significantly for cultures grown in sucrose medium. Interestingly, despite an abundance of essential nutrients transcription levels of functions related to uptake and processing of nitrogen and iron became increased for cultures grown on sucrose as sole carbon source. Transcriptome data were also used to analyze putative regulatory relationships. In addition to the small RNA csrABCD regulon, which seems to play a role in the physiological adaptation and possibly the shift between free-living and plant-associated endophytic life style of Enterobacter sp. 638, our results also pointed to the involvement of rcsAB in controlling responses by Enterobacter sp. 638 to a plant-associated life style. Targeted mutagenesis was used to confirm this role and showed that compared to wild-type Enterobacter sp. 638 a ΔrcsB mutant was affected in its plant growth promoting ability.

AN - 1641018378; 25131339 AB - We report use of PEG-DSPE coated oxidized graphene nanoribbons (O-GNR-PEG-DSPE) as agent for delivery of anti-tumor drug Lucanthone (Luc) into Glioblastoma Multiformae (GBM) cells targeting base excision repair enzyme APE-1 (Apurinic endonuclease-1). Lucanthone, an endonuclease inhibitor of APE-1, was loaded onto O-GNR-PEG-DSPEs using a simple non-covalent method. We found its uptake by GBM cell line U251 exceeding 67% and 60% in APE-1-overexpressing U251, post 24h. However, their uptake was ~38% and 29% by MCF-7 and rat glial progenitor cells (CG-4), respectively. TEM analysis of U251 showed large aggregates of O-GNR-PEG-DSPE in vesicles. Luc-O-GNR-PEG-DSPE was significantly toxic to U251 but showed little/no toxicity when exposed to MCF-7/CG-4 cells. This differential uptake effect can be exploited to use O-GNR-PEG-DSPEs as a vehicle for Luc delivery to GBM, while reducing nonspecific cytotoxicity to the surrounding healthy tissue. Cell death in U251 was necrotic, probably due to oxidative degradation of APE-1.

AN - 1640483349; 25352572 AB - Current drinking water standards for chromium are for the combined total of both hexavalent and trivalent chromium (Cr(VI) and Cr(III)). However, recent studies have shown that Cr(III) is not carcinogenic to rodents, whereas mice chronically exposed to high levels of Cr(VI) developed duodenal tumors. These findings may suggest the need for environmental standards specific for Cr(VI). Whether the intestinal tumors arose through a mutagenic or non-mutagenic mode of action (MOA) greatly impacts how drinking water standards for Cr(VI) are derived. Herein, X-ray fluorescence (spectro)microscopy (µ-XRF) was used to image the Cr content in the villus and crypt regions of duodena from B6C3F1 mice exposed to 180 mg/l Cr(VI) in drinking water for 13 weeks. DNA damage was also assessed by γ-H2AX immunostaining. Exposure to Cr(VI) induced villus blunting and crypt hyperplasia in the duodenum--the latter evidenced by lengthening of the crypt compartment by ∼2-fold with a concomitant 1.5-fold increase in the number of crypt enterocytes. γ-H2AX immunostaining was elevated in villi, but not in the crypt compartment. µ-XRF maps revealed mean Cr levels >30 times higher in duodenal villi than crypt regions; mean Cr levels in crypt regions were only slightly above background signal. Despite the presence of Cr and elevated γ-H2AX immunoreactivity in villi, no aberrant foci indicative of transformation were evident. These findings do not support a MOA for intestinal carcinogenesis involving direct Cr-DNA interaction in intestinal stem cells, but rather support a non-mutagenic MOA involving chronic wounding of intestinal villi and crypt cell hyperplasia.

of toxin (Rot), a central regulator of Staphylococcus aureus virulence. AN - 1634275160; 25331435 AB - Staphylococcus aureus is responsible for a large number of diverse infections worldwide. In order to support its pathogenic lifestyle, S. aureus has to regulate the expression of virulence factors in a coordinated fashion. One of the central regulators of the S. aureus virulence regulatory networks is the transcription factor repressor of toxin (Rot). Rot plays a key role in regulating S. aureus virulence through activation or repression of promoters that control expression of a large number of critical virulence factors. However, the mechanism by which Rot mediates gene regulation has remained elusive. Here, we have determined the crystal structure of Rot and used this information to probe the contribution made by specific residues to Rot function. Rot was found to form a dimer, with each monomer harboring a winged helix-turn-helix (WHTH) DNA-binding motif. Despite an overall acidic pI, the asymmetric electrostatic charge profile suggests that Rot can orient the WHTH domain to bind DNA. Structure-based site-directed mutagenesis studies demonstrated that R(91), at the tip of the wing, plays an important role in DNA binding, likely through interaction with the minor groove. We also found that Y(66), predicted to bind within the major groove, contributes to Rot interaction with target promoters. Evaluation of Rot binding to different activated and repressed promoters revealed that certain mutations on Rot exhibit promoter-specific effects, suggesting for the first time that Rot differentially interacts with target promoters.

AN - 1629954845; 25107347 AB - The inhalation of mineral particulates and other earth materials, such as coal, can initiate or enhance disease in humans. Workers in occupations with high particulate exposure, such as mining, are particularly at risk. The ability of a material to generate an inflammatory stress response (ISR), a measure of particle toxicity, is a useful tool in evaluating said exposure risk. ISR is defined as the upregulation of cellular reactive oxygen species (ROS) normalized to cell viability. This study compares the ISR of A549 human lung epithelial cells after exposure to well-characterized common metal-sulfide ore mineral separates. The evaluation of the deleterious nature of ore minerals is based on a range of particle loadings (serial dilutions of 0.002m(2)/mL stock) and exposure periods (beginning at 30min and measured systematically for up to 24h). There is a wide range in ISR values generated by the ore minerals. The ISR values produced by the sphalerite samples are within the range of inert materials. Arsenopyrite generated a small ISR that was largely driven by cell death. Galena showed a similar, but more pronounced response. Copper-bearing ore minerals generated the greatest ISR, both by upregulating cellular ROS and generating substantial and sustained cell death. Chalcopyrite and bornite, both containing ferrous iron, generated the greatest ISR overall. Particles containing Fenton metals as major constituents produce the highest ISR, while other heavy metals mainly generate cell death. This study highlights the importance of evaluating the chemistry, oxidation states and structure of a material when assessing risk management.

2016-077705 AB - Commercial-scale methane (CH (sub 4) ) extraction from natural hydrate deposits remains a challenge due to, among other factors, a poor understanding of hydrate-host sediment interactions under low-temperature and high-pressure conditions that are conducive to their existence. We report the use of synchrotron X-ray computed microtomography (CMT) to image, for the first time, time-resolved pore-scale methane CH (sub 4) hydrate growth from an aqueous solution containing 5 wt % barium chloride (BaCl (sub 2) ) and pressurized CH (sub 4) hosted in glass beads, all contained in an aluminum cell with an effective volume of 3.5 mL. Multiple two-dimensional (2-D) cross-sectional images show CH (sub 4) hydrates, with 7.5 mu m resolution, distributed in patches throughout the system without dependence on distance from the cell walls. The time-resolved three-dimensional (3-D) images, constructed from the 2-D slices, exhibited pore-filling hydrate formation from dissolved CH (sub 4) gas, similar to natural CH (sub 4) hydrates (sI) in the marine environment. Furthermore, the 3-D images show that the aqueous phase was the wetting phase of the glass beads, i.e., the host and the formed hydrate were separated by an aqueous layer. These results provide some fundamental understanding of the nucleation phenomenon of gas hydrate formation at the pore scale. Pore-filling CH (sub 4) hydrate growth is likely to result in a reduced bulk modulus, and thus, could affect seafloor stability during the reverse phenomenon, i.e., dissociation of natural hydrate deposits.

Although some parameterizations started to address the issue of subgrid variability by introducing a subgrid probability distribution function for relevant quantities, the spatial structure has been typically ignored and thus the subgrid-scale interactions cannot be accounted for physically. Here we present a new statistical-physics-like approach whereby the spatial autocorrelation function can be used to physically capture the net effects of subgrid cloud interaction with radiation. The new approach is able to faithfully reproduce the Monte Carlo 3D simulation results with several orders less computational cost, allowing for more realistic representation of cloud radiation interactions in large-scale models.

(2013). The ranges of these quantities given in these assessments and also in the Fourth (2007) IPCC Assessment are analyzed here within the framework of a planetary energy balance model, taking into account the observed increase in global mean surface temperature over the instrumental record together with best estimates of the rate of increase of planetary heat content. This analysis shows systematic differences among the several assessments and apparent inconsistencies within individual assessments. Importantly, the likely range of ECS to doubled CO sub(2) given in AR5, 1.5-4.5 K/(3.7 W m super(-2)) exceeds the range inferred from the assessed likely range of forcing, 1.2-2.9 K/(3.7 W m super(-2)), where 3.7 W m super(-2) denotes the forcing for doubled CO sub(2). Such differences underscore the need to identify their causes and reduce the underlying uncertainties. Explanations might involve underestimated negative aerosol forcing, overestimated total forcing, overestimated climate sensitivity, poorly constrained ocean heating, limitations of the energy balance model, or a combination of effects. Key Points * Recent assessments of climate sensitivity exhibit apparent inconsistencies. * Causes of the inconsistencies and differences need to be identified.

Given that most synchrotron facilities have user programs which grant academic researchers access to facilities and x-ray imaging equipment free of charge, a key limitation or hindrance for small research groups interested in conducting x-ray imaging experiments is the financial cost associated with post-experiment data analysis. While the cost of high performance computing hardware continues to decrease, expenses associated with licensing commercial software packages for quantitative image analysis continue to increase, with current prices being as high as $24,000 USD, for a single user license. As construction of the Nation's newest synchrotron accelerator nears completion, a significant effort is being made here at the National Synchrotron Light Source II (NSLS-II), Brookhaven National Laboratory (BNL), to provide an open-source, experiment-to-publication toolbox that reduces the financial and technical 'activation energy' required for performing sophisticated quantitative analysis of multidimensional porous media data sets, collected using cutting-edge x-ray imaging techniques. Implementation focuses on leveraging existing open-source projects and developing additional tools for quantitative analysis. We will present an overview of the software suite that is in development here at BNL including major design decisions, a demonstration of several test cases illustrating currently available quantitative tools for analysis and characterization of multidimensional porous media image data sets and plans for their future development.

Although uncertainties associated with AF-derived paleointensity estimates are up to a factor of 3, these values are too high to be explained by current lunar dynamo models: based on estimates of the power available to drive a dynamo in the early history of the Moon, it is expected that the field intensity should have been of the order of a few mu T. Thermal demagnetization-based techniques such as the Thellier-Thellier paleointensity method have much lower uncertainties on the paleofield, but attempts have consistently failed due to alteration of the metal-bearing lunar samples when heated. We have recently designed the first system to conduct thermal demagnetization with oxygen fugacity control using mixtures of H2 and CO2 to mitigate alteration. We are applying this method to the following lunar samples: Regolith breccia 15498. Impact melt from this breccia acquired a magnetization at 1.0-1.3 Ga. We conducted a Thellier-Thellier paleointensity experiment in a controlled atmosphere with oxygen fugacity at IW-1 log(atm). pTRM checks indicate that alteration is negligible up to 500 degrees C. A paleointensity of 3.2 mu T is obtained for the origin-trending high-temperature (>250 degrees C) component. This is consistent with estimates based on AF-demagnetization data. Troctolite 76535. A single plagioclase crystal from 4.2 Gyr-old troctolite 76535 was thermally demagnetized in a controlled atmosphere with oxygen fugacity at IW-1 log(atm). The synchrotron transmission X-ray microscopy and hysteresis parameters show that the major magnetization carriers are fine-grained pseudo-single domain metal inclusions. Due to the small size and weak magnetization of the sample (natural remanent magnetization (NRM) approximately 5 X 10-12 Am2), measurements are performed with a SQUID microscope. The NRM is stable in direction and intensity up to 450 degrees C, and rapidly decays between 450 degrees C and 550 degrees C. Partial TRM (pTRM) acquisitions were performed at 450 degrees C and 550 degrees C. Based on this limited data, a paleofield of at least 45 mu T is obtained, which is consistent with estimates given by AF methods.

The small sizes of these bodies ( approximately 102 km) enable a new opportunity to understand the physics of dynamo generation in a size regime with distinct thermal evolution parameters that are more accessible to model than planets. One key unknown about planetesimal dynamos is their onset time. Theoretical studies have suggested that it might occur instantaneously after large-scale melting (Weiss et al. 2008, Elkins-Tanton et al. 2011) while others have argued that a dynamo could be delayed by approximately 6 My (Sterenborg and Crowley 2013) or longer. Here we present the first paleomagnetic study that has constrained the onset time of a planetesimal dynamo, which has key implications for the physics of core formation, planetary thermal evolution and dynamo generation mechanisms. Our study focused on angrites, a group of ancient basaltic achondrites from near the surface of an early differentiated planetesimal. With unshocked, unbrecciated textures and Pb/Pb ages ranging from only approximately 3-10 My younger than the formation of calcium aluminum inclusions (CAIs), they are among the oldest known and best preserved planetary igneous rocks. We used a new CO2 + H2 gas mixture system (Suavet et al. 2014) for controlled oxygen fugacity thermal paleointensity experiments on two of the oldest angrites (D'Orbigny and SAH 99555; 4564.4 Ma) and a younger angrite (Angra dos Reis; 4557.7 Ma). For D'Orbigny and SAH 99555, we found that the natural remanence (NRM) demagnetizes at much lower temperatures than lab-applied thermoremanence (TRM), indicating that their NRMs are dominantly overprints from the Earth's field and hand magnets. In contrast, the NRM of Angra dos Reis behaves similarly to a TRM, confirming its thermal origin. We estimate the paleointensities to be < 0.2 mu T for D'Orbigny and SAH 99555 and approximately 10 mu T for Angra dos Reis. This indicates that the angrite parent body dynamo originated between 3 and 10 My after CAI formation. Our results are consistent with planetesimal evolution models calling for dynamos delayed by mantle heating due to radiogenic 26Al. Furthermore, these data suggest that external nebular fields in the angrite parent body region had declined to < 0.2 mu T at 3 My after CAI formation.

However, because uncalibrated magnetic extraction techniques were used to provide material for TEM imaging of the biogenic magnetite, it is difficult to quantitatively analyze their concentration in the bulk clay. In this study, we use a synchrotron transmission X-ray microscope to image bulk CIE clay. We first take mosaic images of sub-millimeter-sized bulk clay samples, in which we can identify many of the various types of giant biogenic magnetite crystals, as well as several other types of iron minerals, such as pyrite framboids, siderite, and detrital magnetite. However, limited by the instrument resolution ( approximately 50 nm), we are not able to identify MTB chains let alone isolated magnetic nanoparticles that may be abundant the clay. To quantitatively estimate the concentration of the giant biogenic magnetite, we re-deposited the bulk clay sample in an alcohol solution on a silicon nitride membrane for 2D X-ray scans. After scanning a total area of 0.55 mm2 with average clay thickness of 4 mu m, we identified approximately 40 spearheads, approximately 5 spindles and a few elongated rods and estimated their total magnetization as SD particles to be less than about 10% of the mass normalized clay for the scanned area. This result suggests that the giant biogenic magnetite is not a major source of the SD signal for the clay and is in good agreement with rock magnetic analyses using high-resolution first-order reversal curves and thermal fluctuation tomography on bulk CIE clay showing that most of the magnetite occurs as isolated, near-equant SD particles [Wang et al. 2013 PNAS]. This would also exclude a significant contribution from MTB chains and points to a non-biogenic origin, such as a comet impact plume condensate, for the magnetic nanoparticles [Kent et al. 2003 EPSL] in the very rapidly deposited CIE clays [Wright & Schaller 2014 PNAS].

Formation waters have often a high ionic strength. In this study, we determined the zeta potential (zeta ) of anatase in potassium chloride solutions with concentrations up to 3M (25 degrees C). The zeta potential is the potential at the hydrodynamic shear plane. In this study, we made use of the electro-acoustic effect. This effect is based on the development of a measureable potential/current when the electrical double layer outside the shearplane is separated from a charged particle through rapid oscillation induced by a sound wave. The advantage of this type of measurement is that the particles are not subjected to a high electric field (common to typical zeta potential measurements), which leads to electrode reactions and a shift of solution pH. Measurements were collected by subtracting the ion vibration current (IVI) due to the presence of potassium and chloride ions from the CVI. The correction is necessary for measurements in solutions with I > 0.25 M. This subtraction was done at each of the measurement conditions by centrifuging the slurrly, measuring the IVI of the supernatant, reconstituting the slurry, and then measuring CVI of the slurry. Subtraction of IVI at each condition is critical because IVI changes with pH and accounts for most of raw signal. The results show that the anatase isoelectric point shifts from a pH approximately 6.5 to a value of approximately 4.5 at 1M KCl. At ionic strength in excess of 1 M KCl, the surface appears to be slightly negatively charged accross the pH range accessible by this technique (pH 2.5-10). The loss of an isoelectric point suggests that KCl is no longer an indifferent electrolyte at 1 M KCl and higher. The results are in disagreement with earlier measurements in which anatase was shown to have a positive charge at high ionic strength across the pH scale. The difference between the current and earlier work is likely a result of the IVI correction. While anatase is unlikely to be of importance in a waste environment, the work provides a method to determine charge on more relevant mineral surfaces. This can then lead to a better representation of the fate for radionuclides in the subsurface.

AN - 1718051841; 2015-092427 AB - Metal oxides are a major component of suspended aerosol particulate matter. The molecular level understanding of metal oxide surfaces has important implications in trace gas adsorption and/or chemical processing in atmospheric aerosol chemistry. The extent to which water molecularly adsorbs and/or dissociates at metal oxide interfaces under ambient conditions is becoming increasingly recognized through fundamental studies via spectroscopy and microscopy tools. We will be presenting recent efforts to understand the interfacial chemistry of metal oxide single crystal and thin film surfaces exposed to ambient water vapor conditions using in-vacuo X-ray Photoelectron Spectroscopy (XPS), ambient pressure XPS, scanning tunneling microscopy (STM), and computer simulations. Results highlight the importance of surface chemistry, metal oxide crystal termination, and external humidity conditions on the interfacial dynamics and chemistry of water at metal oxide interfaces.

AN - 1625345645; 25295712 AB - An interface between toluene and water was utilized to synthesize ca. 10 nm thick of anatase TiO2 nanosheets (NSs) with 82% exposure of {001} facets. In this procedure, highly corrosive and toxic HF, which was generally used to prepare TiO2 NSs with largely exposed high energy facets, was avoided. Furthermore, the surfaces of the NSs were quite clean as suggested by XPS analysis. Serving as anode materials in lithium-ion batteries, these as-prepared anatase TiO2 NSs manifested a low initial irreversible capacity loss (12.5% at 1 C), an excellent capacity retention at 10 C charge-discharge rate (101.9 mA h g(-1) after 100 cycles), and enhanced rate performance at 0.5-10 C current rates in compared with Degussa P25 TiO2 nanoparticles (NPs). Their excellent electrochemical performances were mainly derived from the large proportion of {001} exposed facets and a very short diffusion pathway, which allowed fast and efficient Li(+) transportation in the electrodes.

AN - 1610757337; 25219849 AB - Magnetoresistance is the change in a material's electrical resistance in response to an applied magnetic field. Materials with large magnetoresistance have found use as magnetic sensors, in magnetic memory, and in hard drives at room temperature, and their rarity has motivated many fundamental studies in materials physics at low temperatures. Here we report the observation of an extremely large positive magnetoresistance at low temperatures in the non-magnetic layered transition-metal dichalcogenide WTe2: 452,700 per cent at 4.5 kelvins in a magnetic field of 14.7 teslas, and 13 million per cent at 0.53 kelvins in a magnetic field of 60 teslas. In contrast with other materials, there is no saturation of the magnetoresistance value even at very high applied fields. Determination of the origin and consequences of this effect, and the fabrication of thin films, nanostructures and devices based on the extremely large positive magnetoresistance of WTe2, will represent a significant new direction in the study of magnetoresistivity.

The data support a crucial role for triacylglycerol metabolism in fatty acid breakdown in leaves. Triacylglycerol (TAG) metabolism is a key aspect of intracellular lipid homeostasis in yeast and mammals, but its role in vegetative tissues of plants remains poorly defined. We previously reported that PHOSPHOLIPID:DIACYLGLYCEROL ACYLTRANSFERASE1 (PDAT1) is crucial for diverting fatty acids (FAs) from membrane lipid synthesis to TAG and thereby protecting against FA-induced cell death in leaves. Here, we show that overexpression of PDAT1 enhances the turnover of FAs in leaf lipids. Using the trigalactosyldiacylglycerol1-1 (tgd1-1) mutant, which displays substantially enhanced PDAT1-mediated TAG synthesis, we demonstrate that disruption of SUGAR-DEPENDENT1 (SDP1) TAG lipase or PEROXISOMAL TRANSPORTER1 (PXA1) severely decreases FA turnover, leading to increases in leaf TAG accumulation, to 9% of dry weight, and in total leaf lipid, by 3-fold. The membrane lipid composition of tgd1-1 sdp1-4 and tgd1-1 pxa1-2 double mutants is altered, and their growth and development are compromised. We also show that two Arabidopsis thaliana lipin homologs provide most of the diacylglycerol for TAG synthesis and that loss of their functions markedly reduces TAG content, but with only minor impact on eukaryotic galactolipid synthesis. Collectively, these results show that Arabidopsis lipins, along with PDAT1 and SDP1, function synergistically in directing FAs toward peroxisomal beta -oxidation via TAG intermediates, thereby maintaining membrane lipid homeostasis in leaves.

Remote sensing research at the leaf and canopy scales has demonstrated the ability to characterize the biochemical status of vegetation canopies using reflectance spectroscopy, including at the leaf level and canopy level from air- and spaceborne imaging spectrometers. We developed a set of accurate and precise spectroscopic calibrations for the determination of leaf chemistry, morphology, and isotopic composition of temperate and boreal tree species using spectra of dried and ground leaf material. This study demonstrates the potential for rapid and accurate estimation of key foliar traits of forest canopies that are important for ecological research and modeling activities, with a single calibration equation valid over a wide range of northern temperate and boreal species and leaf physiognomies. The results provide the basis to characterize important variability between and within species, and across ecological gradients using a rapid, cost-effective, easily replicated method.

AN - 1561974659; 25208691 AB - Galvanic replacement reactions provide an elegant way of transforming solid nanoparticles into complex hollow morphologies. Conventionally, galvanic replacement is studied by stopping the reaction at different stages and characterizing the products ex situ. In situ observations by liquid-cell electron microscopy can provide insight into mechanisms, rates and possible modifications of galvanic replacement reactions in the native solution environment. Here we use liquid-cell electron microscopy to investigate galvanic replacement reactions between silver nanoparticle templates and aqueous palladium salt solutions. Our in situ observations follow the transformation of the silver nanoparticles into hollow silver-palladium nanostructures. While the silver-palladium nanocages have morphologies similar to those obtained in ex situ control experiments the reaction rates are much higher, indicating that the electron beam strongly affects the galvanic-type process in the liquid-cell. By using scavengers added to the aqueous solution we identify the role of radicals generated via radiolysis by high-energy electrons in modifying galvanic reactions.

The probability of transformation is presumed to scale with the number of potentially lethal damages that are repaired in a surviving cell or the interactions of such damages. The theory predicts that at doses corresponding to high survival, the transformation frequency is the sum of simple polynomial functions of dose; linear, quadratic, etc, essentially as described in widely used linear-quadratic expressions. The presumed cause of this difference is that, unlike UV photons, a single x-ray or neutron may generate more than one lethal damage in a cell, so the distribution of such damages in the population is not accurately described by Poisson statistics. However, the complete sigmodial dose-response data for neoplastic transformations can be fit using the repair-dependent functions with all parameters determined only from transformation frequency data.

Part 1: Retrieved cloud liquid water path at three ARM sites AN - 1622617815; 20864926 AB - Statistical characteristics of cloud variability are examined for their dependence on averaging scales and best representation of probability density function with the decade-long retrieval products of cloud liquid water path (LWP) from the tropical western Pacific (TWP), Southern Great Plains (SGP), and North Slope of Alaska (NSA) sites of the Department of Energy's Atmospheric Radiation Measurement Program. The statistical moments of LWP show some seasonal variation at the SGP and NSA sites but not much at the TWP site. It is found that the standard deviation, relative dispersion (the ratio of the standard deviation to the mean), and skewness all quickly increase with the averaging window size when the window size is small and become more or less flat when the window size exceeds 12h. On average, the cloud LWP at the TWP site has the largest values of standard deviation, relative dispersion, and skewness, whereas the NSA site exhibits the least. Correlation analysis shows that there is a positive correlation between the mean LWP and the standard deviation. The skewness is found to be closely related to the relative dispersion with a correlation coefficient of 0.6. The comparison further shows that the lognormal, Weibull, and gamma distributions reasonably explain the observed relationship between skewness and relative dispersion over a wide range of scales.

Part 2: Implication for parameterizations of microphysical and radiative transfer processes in climate models AN - 1622609135; 20864922 AB - The effects of subgrid cloud variability on grid-average microphysical rates and radiative fluxes are examined by use of long-term retrieval products at the Tropical West Pacific, Southern Great Plains, and North Slope of Alaska sites of the Department of Energy's Atmospheric Radiation Measurement program. Four commonly used distribution functions, the truncated Gaussian, Gamma, lognormal, and Weibull distributions, are constrained to have the same mean and standard deviation as observed cloud liquid water content. The probability density functions are then used to upscale relevant physical processes to obtain grid-average process rates. It is found that the truncated Gaussian representation results in up to 30% mean bias in autoconversion rate, whereas the mean bias for the lognormal representation is about 10%. The Gamma and Weibull distribution function performs the best for the grid-average autoconversion rate with the mean relative bias less than 5%. For radiative fluxes, the lognormal and truncated Gaussian representations perform better than the Gamma and Weibull representations. The results show that the optimal choice of subgrid cloud distribution function depends on the nonlinearity of the process of interest, and thus, there is no single distribution function that works best for all parameterizations. Examination of the scale (window size) dependence of the mean bias indicates that the bias in grid-average process rates monotonically increases with increasing window sizes, suggesting the increasing importance of subgrid variability with increasing grid sizes.

Emphasis is on the usefulness of radar observations from the C-band and X-band scanning ARM precipitation radars (CSAPR and XSAPR, respectively) for rainfall estimation products to distances within 100 km of the Lamont, Oklahoma, ARM facility. The study utilizes a dense collection of collocated ARM, NASA Global Precipitation Measurement, and nearby surface Oklahoma Mesonet gauge records to evaluate radar-based hourly rainfall products and campaign-optimized methods over individual gauges and for areal rainfall characterizations. Rainfall products are also evaluated against the performance of a regional NWS Weather Surveillance Radar-1988 Doppler (WSR-88D) S-band dual-polarization radar product. Results indicate that the CSAPR system may achieve similar point and arealgauge bias and root-mean-square (RMS) error performance to a WSR-88D reference for the variety of MC3E deep convective events sampled. The best campaign rainfall performance was achieved when using radar relations capitalizing on estimates of the specific attenuation from the CSAPR system. The XSAPRs demonstrate limited capabilities, having modest success in comparison with the WSR-88D reference for hourly rainfall accumulations that are under 10 mm.

AN - 1558521281; 25006244 AB - Phytochromes are multidomain photoswitches that drive light perception in plants and microorganisms by coupling photoreversible isomerization of their bilin chromophore to various signaling cascades. How changes in bilin conformation affect output by these photoreceptors remains poorly resolved and might include several species-specific routes. Here, we present detailed three-dimensional models of the photosensing module and a picture of an entire dimeric photoreceptor through structural analysis of the Deinococcus radiodurans phytochrome BphP assembled with biliverdin (BV). A 1.16-Å resolution crystal structure of the bilin-binding pocket in the dark-adapted red light-absorbing state illuminated the intricate network of bilin/protein/water interactions and confirmed the protonation and ZZZssa conformation of BV. Structural and spectroscopic comparisons with the photochemically compromised D207A mutant revealed that substitutions of Asp-207 allow inclusion of cyclic porphyrins in addition to BV. A crystal structure of the entire photosensing module showed a head-to-head, twisted dimeric arrangement with bowed helical spines and a hairpin protrusion connecting the cGMP phosphodiesterase/adenylyl cyclase/FhlA (GAF) and phytochrome-specific (PHY) domains. A key conserved hairpin feature is its anti-parallel, two β-strand stem, which we show by mutagenesis to be critical for BphP photochemistry. Comparisons of single particle electron microscopic images of the full-length BphP dimer in the red light-absorbing state and the photoactivated far-red light-absorbing state revealed a large scale reorientation of the PHY domain relative to the GAF domain, which alters the position of the downstream histidine kinase output module. Together, our data support a toggle model whereby bilin photoisomerization alters GAF/PHY domain interactions through conformational modification of the hairpin, which regulates signaling by impacting the relationship between sister output modules.

AN - 1558523325; 25039789 AB - Superhydrophobic sponges and sponge-like materials have attracted great attention recently as potential sorbent materials for oil spill cleanup due to their excellent sorption capacity and high selectivity. A major challenge to their broad use is the fabrication of superhydrophobic sponges with superior recyclability, good mechanical strength, low cost, and manufacture scalability. In this study, we demonstrate a facile, cost-effective, and scalable method to fabricate robust, superhydrophobic sponges through the silanization of commercial melamine sponges via a solution-immersion process. The silanization was achieved through secondary amine groups on the surface of the sponge skeletons with alkylsilane compounds, forming self-assembled monolayers on the surface of sponge skeletons. This resulted in our ability to tune the surface properties of the sponges from being hydrophilic to superhydrophobic with a water contact angle of 151.0°. The superhydrophobic silanized melamine sponge exhibited excellent sorption capacity for a wide range of organic solvents and oils, from 82 to 163 times its own weight, depending on the polarity and density of the employed organic solvents and oils, and high selectivity and outstanding recyclability with an absorption capacity retention greater than 90% after 1000 cycles. These findings offer an effective approach for oil spill containment and environmental remediation.

To examine the existing techniques of cloud property retrieval and explore the underlying reasons for uncertainties, a newly developed approach that allows for simultaneous retrievals of cloud fraction and cloud albedo from ground-based shortwave broadband radiation measurements, XL2013, is used to derive cloud fraction and cloud albedo from ground-based shortwave broadband radiation measurements at the Department of Energy Atmospheric Radiation Measurement Southern Great Plains site. The new results are compared with the separate retrieval of cloud fraction and cloud albedo using Long2006 and Liu2011, respectively. The retrievals from the broadband radiation measurements are further compared with those based on shortwave spectral measurements (Min2008). The comparison shows overall good agreement between the retrievals of both cloud fraction and cloud albedo, with noted differences, however. The Long2006 and Min2008 cloud fractions are greater on average than the XL2013 values. Compared to Min2008 and Liu2011, the XL2013 cloud albedo tends to be greater for thin clouds but smaller for thick clouds, with the differences decreasing with increasing cloud fraction; the neglect of land surface albedo and cloud absorption by Liu2011 also contributes the difference in cloud albedo. Further analysis reveals that the approaches that retrieve cloud fraction and cloud albedo separately may suffer from mutual contamination of errors in retrieved cloud fraction and cloud albedo.

The electrochemical results show that deposition of small SnO sub(2) NPs onto the pc-Pt electrode surface significantly enhances the catalytic performance of Pt. Infrared spectroscopy measurements show the effect that small SnO sub(2) particles have on the removal of CO from the Pt surface and suggest that the electrocatalytic C-C bond splitting activity of Pt, the key step in full conversion of ethanol to CO sub(2), is not affected by the addition of the -OH species provided by the SnO sub(2) particles. Also, it is shown that controlled deposition of SnO sub(2) is needed in order to control the rate of partial oxidation to acetic acid compared to full oxidation to CO sub(2). The combined results provide new insight into the role of SnO sub(2) co-catalysts in promoting the electro-oxidation of ethanol to CO sub(2) on Pt surfaces.

Although recent studies indicate that salicylic acid (SA) may also be important in this context by interfering with IAA signaling, comparatively little is known about its impact on the plant's physiology, metabolism, and growth characteristics. Using carbon-11, a short-lived radioisotope (t sub(1/2) = 20.4 min) administered as super(11)CO sub(2) to maize plants (B73), we measured changes in these functions using SA and IAA treatments. IAA application decreased total root biomass, though it increased lateral root growth at the expense of primary root elongation. IAA-mediated inhibition of root growth was correlated with decreased super(11)CO sub(2) fixation, photosystem II (PSII) efficiency, and total leaf carbon export of super(11)C-photoassimilates and their allocation belowground. Furthermore, IAA application increased leaf starch content. On the other hand, SA application increased total root biomass, super(11)CO sub(2) fixation, PSII efficiency, and leaf carbon export of super(11)C-photoassimilates, but it decreased leaf starch content. IAA and SA induction patterns were also examined after root-herbivore attack by Diabrotica virgifera to place possible hormone crosstalk into a realistic environmental context. We found that 4 days after infestation, IAA was induced in the midzone and root tip, whereas SA was induced only in the upper proximal zone of damaged roots. We conclude that antagonistic crosstalk exists between IAA and SA which can affect the development of maize plants, particularly through alteration of the root system's architecture, and we propose that the integration of both signals may shape the plant's response to environmental stress.

Observations are obtained from an impact disdrometer with a near continuous record of operation over five consecutive wet seasons (200611). Bulk rainfall characteristics are partitioned according to diurnal accumulation, convective and stratiform precipitation classifications, objective monsoonal regime, and MJO phase. Findings support previous Darwin studies suggesting a significant diurnal and DSD parameter signal associated with both convectivestratiform and wet season monsoonal regime classification. Negligible MJO phase influence is determined for cumulative disdrometric statistics over the Darwin location.

The relatively low rate capability is one of the major problems that need to be resolved for these materials. To gain insight into the key factors that limit the rate capability, in situ X-ray absorption spectroscopy (XAS) and X-ray diffraction (XRD) studies of the cathode material, Li sub(1.2)Ni sub(0.15)Co sub(0.1)Mn sub(0.55)O sub(2) [0.5Li(Ni sub(0.375)Co sub(0.25) Mn sub(0.375))O sub(2).0.5 Li sub(2)MnO sub(3)], are carried out. The partial capacity contributed by different structural components and transition metal elements is elucidated and correlated with local structure changes. The characteristic reaction kinetics for each element are identified using a novel time-resolved XAS technique. Direct experimental evidence is obtained showing that Mn sites have much poorer reaction kinetics both before and after the initial activation of Li sub(2)MnO sub(3), compared to Ni and Co. These results indicate that Li sub(2)MnO sub(3) may be the key component that limits the rate capability of Li-rich layered materials and provide guidance for designing Li-rich layered materials with the desired balance of energy density and rate capability for different applications. In the cathode material Li sub(1.2)Ni sub(0.15)Co sub(0.1)Mn sub(0.55)O sub(2) [0.5Li(Ni sub(0.375)Co sub(0.25)M n sub(0.375))O sub(2).0.5Li sub(2)MnO sub(3)] the capacity contributed from different components and elements is elucidated and correlated with the local structure changes. The reaction kinetic characteristics for each element are been identified and differentiated. It is observed that Li sub(2)MnO sub(3) may be the key component determining the rate capability of the Li-rich layered materials.

AN - 1490752934; 24316798 AB - As green solvents ionic liquids (ILs) show high potential in nuclear industry for extraction and purification of actinides. However, to date relatively little information has been gained on ILs application in microbial processes, for example biosorption of radionuclides. We investigated the effects of three ILs, 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6), N-ethylpyridinium trifluoroacetate (EtPyCF3COO) and N-ethylpyridinium tetrafluoroborate (EtPyBF4) on the growth and biosorption of uranium by Clostridium sp. The ILs affected the growth of the bacterium as evidenced by decreases in optical density, total gas production, and organic acids production from glucose metabolism. The IC50-48h of three ILs decreased in the order of BMIMPF6 (8.26mM)>EtPyBF4 (7.04mM)>EtPyCF3COO (4.05mM). Uranium biosorption by the bacterial cells decreased by 75% in the presence of 1% (v/v) BMIMPF6 and by about 90% with 1% (v/v) EtPyBF4 or EtPyCF3COO, in comparison to the control without ILs. The diminished biosorption may be attributed to the membrane damages induced by EtPyBF4 and EtPyCF3COO, which can be visualized by Transmission Electron Microscope (TEM) analysis. Energy-dispersive X-ray spectroscopy (EDS) analysis revealed the accumulation of uranium inside peripheral membrane of the cells exposed to uranium alone or with BMIMPF6, while little or no accumulation was observed in the presence of EtPyBF4 and EtPyCF3COO. These results imply that potential toxicity of ILs towards microorganisms is a particularly important issue in limiting its biotechnological applications.

While operating experience with thorium-based fuels has been relatively limited, many design studies have been performed in the US and internationally examining options for the utilization of thorium in a broad spectrum of reactor types. These are motivated by the nuclear and physical characteristics of thorium-based fuels and fuel cycles and their associated benefit including reduced production of plutonium and higher actinides and potential improvements in reactor performance, safety, and waste characteristics.

Detailed physics analyses have been performed for explicit analysis examples to inform the Evaluation and Screening process. This particular fuel cycle analysis example is a three-stage fuel cycle with continuous recycle. The high-level objectives of the fuel cycle are to utilize existing thermal reactor technology, in this example case pressurized water reactors (PWRs) coupled with Th-based fuel to extend uranium resources, while burning transuranic isotopes in an externally driven system, in this example case an Accelerator Driven System (ADS). Figure 1 shows the interpretation of the fuel cycle.

The target cross section (area facing in the beam direction) is proportional to beam current, and determines the shielding requirements of the upstream magnets, the blanket size, and any loss of neutrons in the target volume before they enter the blanket. The target cross section is determined by the size of the drift tube window, which separates the drift tube vacuum from the target. The defining parameter is the areal current density in A/cm super(2) on the window. Note that since beam power is the product of beam energy and current these two parameters can be traded off against each other to optimize the system.

Multiple geogenic processes contribute to the release and mobilization of As and control the spatial variation of low and high-As localizations. The current study focuses on As sorption and release mechanisms from sediment fractions to groundwaters within aquifers. It also probes the extent of bioaccumulation, speciation, and localization of As within rice cultivated in these soils with high As irrigation waters. Results indicate contents of organic matter (OM) within sediments, and dominance of Fe and Mn together play a key role in sorption of As. Extractions from core sediments collected in contrasting low and high-As areas indicate residual and Fe-oxyhydroxide fractions dominating As adsorption. OM-adsorbed As, Fe and Mn were quantified by NaOCl extractions on the sediments. Leftover dissolved organic carbon (DOC) from the above extracts demonstrated sediment-bound organics varying from shallow to deep parts even within the high-As areas. Positive correlations were observed between total As (As (sub T) ) in groundwater and dissolved Fe-Mn ratios; As (sub T) and DOC in groundwater; and bulk As and TOC of sediments. Rice samples collected from low and high-As areas (n=14) and domestically purchased (n=10) were de-husked, dried, ground, and microwave digested. IC-ICP-DRC-MS analyses show a diverse range of As uptake by rice grains cultivated in both dry and wet seasons. Our results indicate rice grains with long and slender (LS) physical dimensions bioconcentrated on average more As than short and stocky (SS) grains. Rice samples that exceeded 125 mu g/kg AsT (n=10) were selected for water digestion and HPLC-ICP-MS analysis for speciation. Organic As (MMA, DMA) and As (V) were undetectable at <1 mu g/kg. As (III) was the dominant species, detected in 40% of samples in concentrations between 6.8 mu g/kg and 52.3 mu g/kg. mu XANES and mu XRF analyses were conducted to further investigate As speciation and map As localization to reveal important uptake mechanisms within rice grains.

This program (available online at http://www.xmaptools.com) provides a method to standardize raw electron microprobe data and includes functions to calculate the oxide weight percent compositions for various minerals. A set of external functions is provided to calculate structural formulae from the standardized analyses as well as to estimate pressure-temperature conditions of crystallization, using empirical and semi-empirical thermobarometers from the literature. Two graphical user interface modules, Chem2D and Triplot3D, are used to plot mineral compositions into binary and ternary diagrams. As an example, the software is used to study a high-pressure Himalayan eclogite sample from the Stak massif in Pakistan. The high-pressure paragenesis consisting of omphacite and garnet has been retrogressed to a symplectitic assemblage of amphibole, plagioclase and clinopyroxene. Mineral compositions corresponding to approximately 165,000 analyses yield estimates for the eclogitic pressure-temperature retrograde path from 25 kbar to 9 kbar. Corresponding pressure-temperature maps were plotted and used to interpret the link between the equilibrium conditions of crystallization and the symplectitic microstructures.

Spectra were measured on several areas within a nearly pure 100 X 200 mu m forsterite grain containing 0.13 wt% Cr. XANES findings indicate highly reduced Cr (super 2+) species, with no clear evidence of Cr (super 3+) or Cr (super 6+) . EXAFS data indicate an average 2.02 Aa Cr-O nearest-neighbor distance, consistent with Cr-O distances found in square-planar Cr (super 2+) O (sub 4) sites observed in synthetic crystalline silicates, and an average 2.69 Aa Cr-Si second-nearest neighbor distance, consistent with Cr (super 2+) substituting for Mg (super 2+) in the forsterite M(1) site. Nearest-neighbor Debye-Waller factor and coordination number parameters indicate Cr (super 2+) is likely entering forsterite in disordered sites that are possible intermediates between M(1) and square-planar Cr (super 2+) O (sub 4) configurations. Preliminary Cr XAS measurements on sulfides within this meteorite also indicate Cr (super 2+) in CrS (sub 6) octahedra.

In this work, pore-network modeling was used to predict permeability based on pore- and pore-throat size distributions determined from analysis of 2D scanning electron microscopy (SEM) images of thin sections and 3D X-ray computed microtomography (CMT) data. The analyzed specimens were a Viking sandstone sample from the Alberta sedimentary basin and an experimental column of reacted Hanford sediments. For the column, a decrease in permeability due to mineral precipitation was estimated, but the permeability estimates were dependent on imaging technique and resolution. X-ray CT imaging has the advantage of reconstructing a 3D pore network while 2D SEM imaging can easily analyze sub-grain and intragranular variations in mineralogy. Pore network models informed by analyses of 2D and 3D images at comparable resolutions produced permeability estimates with relatively good agreement. Large discrepancies in predicted permeabilities resulted from small variations in image resolution. Images with resolutions 0.4 to 4mu m predicted permeabilities differing by orders of magnitude. While lower-resolution scans can analyze larger specimens, small pore throats may be missed due to resolution limitations, which in turn overestimates permeability in a pore-network model in which pore-to-pore conductances are statistically assigned. Conversely, high-resolution scans are capable of capturing small pore throats, but if they are not actually flow-conducting predicted permeabilities will be below expected values. In addition, permeability is underestimated due to misinterpreting surface-roughness features as small pore throats. Comparison of permeability predictions with expected and measured permeability values showed that the largest discrepancies resulted from the highest resolution images and the best predictions of permeability will result from images between 2 and 4mu m resolution. To reduce permeability underestimation from analyses of high-resolution images, a resolution threshold between 3 and 15mu m was found to be effective, but it is not known whether this range is applicable beyond the samples studied here.

Here a new analytical approach is presented that simultaneously infers cloud albedo and cloud fraction from surface-based measurements of total and direct radiative fluxes. An inspection of the analytical formulation reveals that cloud fraction is primarily determined by the relative cloud radiative forcing for the direct radiation, defined as the difference between the clear-sky and all-sky direct downwelling radiative fluxes normalized by the clear-sky direct downwelling radiative fluxes, while cloud albedo is primarily determined by the ratio of the relative cloud radiative forcing for the total downwelling radiation to the relative cloud radiative forcing for the direct radiation. The new analytical approach is validated using synthetic measurements generated by the rapid radiative transfer model (RRTM) algorithm with known cloud inputs and some surface- and satellite-based measurements. The effect of cloud absorption is further corrected based on a suite of numerical experiments. The new approach demonstrates the utility of partitioning total radiation into direct and diffuse radiation, and eliminates the potential contamination of errors in existing approaches that retrieve cloud fraction and cloud albedo separately.

Geological disposal method has been chosen in many countries including Korea. A safety issue after the closure of geological repository has been raised, because microbial activities lead overpressure in the underground facilities through gas production. In particular, biodegradable organic materials derived from low- and intermediate-level radioactive wastes play important role on microbial activities in the geological repository. This study performed large scale in-situ experiments using organic wastes and groundwater, and investigated geochemical alteration and microbial activities at early stage ( nearly equal 63 days) as representative of the period, after closure of the geological repository. The geochemical alteration controlled significantly the microorganism types and populations. Database of the biogeochemical alteration facilitates prediction of radionuclides' mobility and establishment of remedial strategy against unpredictable accidents and hazards at early stage right after closure of the geological repository.

Here the influence of co-injected hydrogen sulfide and sulfur dioxide on the reactivity of hematite-bearing sandstones was evaluated as a function of salt content and water/rock ratio. The reactivity of the Triassic Moenkopi red sandstone under scCO2-dominated conditions (supercritical fluid around the point of injection) and water-dominated conditions (aqueous phase influenced by the injection of scCO2) was studied. Flow-through experiments were used to simulate scCO2-dominated conditions. Crushed sandstone packed in a column was exposed to a co-mingled stream of supercritical CO2 and an aqueous H2S or SO2 solution (75 degrees C). Batch experiments to simulate water-dominated conditions were conducted in small autoclaves that were loaded with crushed sandstone, a small amount of water, and dry ice before to 75 degrees C. The role of water/rock ratio was explored by conducting experiments at a water/rock ratio of 4.3/1 and 1.4/1. The reacted sandstones were recovered at the conclusion of each type of experiment and analyzed for changes in mineralogical composition using X-ray Diffraction. Selected reaction products were also studied using Mossbauer spectroscopy, FTIR, and Visible Near Infrared (VNIR) spectroscopy. The results of the flow through experiments, simulating scCO2-dominated conditions, showed no changes in the iron mineralogy of the sand, regardless of whether pure scCO2 or scCO2 co-mingled with SO2 or H2S was used. By contrast, batch experiments, simulating water-dominated conditions, showed significant changes in iron mineralogy. The presence of sulfide led to the conversion of the hematite component in the sandstone to pyrite at all salt concentrations (0-6 M NaCl). In experiments with sulfide and sulfite, siderite and pyrite formed, but siderite was favored at higher salinity and lower water/rock ratio. Availability of water at the mineral surface might be a critical factor in the reactivity of co-injected sulfur gasses. In the regime dominated by scCO2, co-mingled sulfur gasses do not react with the hematite component in the sandstone. In water-dominated conditions, exposure to SO2 and scCO2 has no effect on the iron mineralogy, but the addition of H2S leads to conversion of hematite to pyrite and siderite, and this conversion increases with higher water content. The implication of this study is that within the scCO2 plume there will be little or no change in permeability as a result of reactions with iron minerals. However, just beyond the plume, co-mingled H2S with or without SO2 will react with hematite and lead to new minerals that may affect permeability.

Cysteine represents an organic molecule with functionalities (O, S, N functional groups) and a C backbone that may mimic the functional groups present in organic matter from terrestrial and aquatic environments. In the present study we explore the redox speciation and coordination environment of Fe and the roles of the various ligand atoms of cysteine (C, N, S) in iron-organic redox coupling and transformations. The changes in oxidation state of Fe, C, N, and S in laboratory-synthesized Fe(II)-cysteine (synthesized from ferrous sulfate) and Fe(III)-cysteine (synthesized from ferric nitrate) complexes are monitored as a function of time using synchrotron X-ray absorption spectroscopy (Fe L (sub 2) , (sub 3) -edge XANES; C, N and S K-edge XANES; Fe K-edge EXAFS) and theoretical multiplet calculations using the program CTM4XAS (Charge Transfer Multiplet for X-ray Absorption Spectroscopy). CTM4XAS calculations show that 80% of the total Fe in both the Fe(II)-cysteine and the Fe(III)-cysteine complexes is present as Fe (super 2+) initially (t=0), thus indicating preservation of Fe(II) in Fe(II)-cysteine and reduction of Fe(III) in Fe(III)-cysteine at initial conditions, the latter caused by an internal electron transfer reaction from S of -SH on the cysteine molecule. After 12 months, however, approximately 60% of the total Fe is present as Fe (super 3+) in the Fe(II)-cysteine complex whereas approximately 67% of the total Fe is present as Fe (super 2+) in the Fe(III)-cysteine complex. The fact that a larger proportion of the Fe in the Fe(III)-cysteine complex remained reduced after 12 months than that in the Fe(II)-cysteine complex suggests that the reduced Fe in Fe(III)-cysteine after 12 months is further stabilized via preferential binding with the donor atoms of cysteine. Stabilization via preferential binding is supported by a coordination environment that changed from tetrahedral Fe (super 2+) binding to S at a distance of 2.3Aa at t=0 for both Fe(II,III)-cysteine complexes, to Fe (super 3+) in an octahedral coordination with O/N atoms at a distance of 2.05Aa (most prevalent in Fe(II)-cysteine) and Fe (super 2+) in tetrahedral coordination with S/O/N atoms at an average distance of 2.15Aa (most prevalent in Fe(III)-cysteine) at t=12 months. Redox changes in the -NH (sub 2) and -SH groups of cysteine accompanied the Fe redox changes thus reflecting the true potential of cysteine as a redox ligand. Our studies of the Fe(II,III)-cysteine complexes add valuable information to the existing literature on the redox chemistry of Fe-cysteine systems by shedding light on the electron exchange pathways that may occur within the complexes and by providing a detailed depiction of the iron-ligand structure and coordination. The presence and persistence of Fe(II) or Fe(III) in complexes with soluble organics have implications for Fe biological availability and Fe mobility and transport in terrestrial as well as in aquatic environments.

AN - 1435844742; 23843033 AB - One means of combining the unique physical and chemical properties of both carbon nanotubes and complementary material motifs (such as metal sulfide quantum dots (QDs), metal oxide nanostructures, and polymers) can be achieved by generating carbon nanotube (CNT)-based heterostructures. These materials can be subsequently utilized as novel and interesting constituent building blocks for the assembly of functional light energy harvesting devices and because of their architectural and functional flexibility, can potentially open up novel means of using and taking advantage of existing renewable energy sources. In this review, we present the reliable and reproducible synthesis of several unique model CNT-based heterostructured systems as well as include an accompanying discussion about the charge transfer and energy flow properties of these materials for their potential incorporation into a range of practical solar energy conversion devices.

AN - 1412162789; 23357359 AB - Protein misfolding and aggregation are the hallmark of a number of diseases including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and the prion diseases. In all cases, a naturally-occurring protein misfolds and forms aggregates that are thought to disrupt cell function through a wide range of mechanisms that are yet to be fully unraveled. Fourier transform infrared (FTIR) spectroscopy is a technique that is sensitive to the secondary structure of proteins and has been widely used to investigate the process of misfolding and aggregate formation. This review focuses on how FTIR spectroscopy and spectroscopic microscopy are being used to evaluate the structural changes in disease-related proteins both in vitro and directly within cells and tissues. Finally, ongoing technological advances will be presented that are enabling time-resolved FTIR imaging of protein aggregation directly within living cells, which can provide insight into the structural intermediates, time scale, and mechanisms of cell toxicity associated with aggregate formation.

Through optimization of the electrolyte and binder, the microsized Na sub(2)Ti sub(3)O sub(7) electrode delivers a reversible capacity of 188 mA h g super(-1) in 1 M NaFSI/PC electrolyte at a current rate of 0.1C in a voltage range of 0.0-3.0 V, with sodium alginate as binder. The average Na storage voltage plateau is found at ca. 0.3 V vs. Na super(+)/Na, in good agreement with a first-principles prediction of 0.35 V. The Na storage properties in Na sub(2)Ti sub(3)O sub(7) are investigated from thermodynamic and kinetic aspects. By reducing particle size, the nanosized Na sub(2)Ti sub(3)O sub(7) exhibits much higher capacity, but still with unsatisfied cyclic properties. The solid-state interphase layer on Na sub(2)Ti sub(3)O sub(7) electrode is analyzed. A zero-current overpotential related to thermodynamic factors is observed for both nano- and microsized Na sub(2)Ti sub(3)O sub(7). The electronic structure, Na super(+) ion transport and conductivity are investigated by the combination of first-principles calculation and electrochemical characterizations. On the basis of the vacancy-hopping mechanism, a quasi-3D energy favorable trajectory is proposed for Na sub(2)Ti sub(3)O sub(7). The Na super(+) ions diffuse between the TiO sub(6) octahedron layers with pretty low activation energy of 0.186 eV. The sodium storage properties of layered Na sub(2)Ti sub(3)O sub(7), as a potential anode material for sodium-ion batteries, are elaborated from thermodynamic and kinetic aspects. An interesting zero-current overpotential related to thermodynamic factors in Na sub(2)Ti sub(3)O sub(7) is studied.

AN - 1426749575; 23286528 AB - Oxides play a central role in important industrial processes, including applications such as the production of renewable energy, remediation of environmental pollutants, and the synthesis of fine chemicals. They were originally used as catalyst supports and were thought to be chemically inert, but now they are used to build catalysts tailored toward improved selectivity and activity in chemical reactions. Many studies have compared the morphological, electronic, and chemical properties of oxide materials with those of unoxidized metals. Researchers know much less about the properties of oxides at the nanoscale, which display distinct behavior from their bulk counterparts. More is known about metal nanoparticles. Inverse-model catalysts, composed of oxide nanoparticles supported on metal or oxide substrates instead of the reverse (oxides supporting metal nanoparticles), are excellent tools for systematically testing the properties of novel catalytic oxide materials. Inverse models are prepared in situ and can be studied with a variety of surface science tools (e.g. scanning tunneling microscopy, X-ray photoemission spectroscopy, ultraviolet photoemission spectroscopy, low-energy electron microscopy) and theoretical tools (e.g. density functional theory). Meanwhile, their catalytic activity can be tested simultaneously in a reactor. This approach makes it possible to identify specific functions or structures that affect catalyst performance or reaction selectivity. Insights gained from these tests help to tailor powder systems, with the primary objective of rational design (experimental and theoretical) of catalysts for specific chemical reactions. This Account describes the properties of inverse catalysts composed of CeOx nanoparticles supported on Cu(111) or CuOx/Cu(111) as determined through the methods described above. Ceria is an important material for redox chemistry because of its interchangeable oxidation states (Ce⁴⁺ and Ce³⁺). Cu(111), meanwhile, is a standard catalyst for reactions such as CO oxidation and the water-gas shift (WGS). This metal serves as an ideal replacement for other noble metals that are neither abundant nor cost effective. To prepare the inverse system we deposited nanoparticles (2-20 nm) of cerium oxide onto the Cu(111) surface. During this process, the Cu(111) surface grows an oxide layer that is characteristic of Cu₂O (Cu¹⁺). This oxide can influence the growth of ceria nanoparticles. Evidence suggests triangular-shaped CeO₂(111) grows on Cu₂O(111) surfaces while rectangular CeO₂(100) grows on Cu₄O₃(111) surfaces. We used the CeOx/Cu₂O/Cu(111) inverse system to study two catalytic processes: the WGS (CO + H₂O → CO₂ + H₂) and CO oxidation (2CO + O₂ → 2CO₂). We discovered that the addition of small amounts of ceria nanoparticles can activate the Cu(111) surface and achieve remarkable enhancement of catalytic activity in the investigated reactions. In the case of the WGS, the CeOx nanoparticle facilitated this process by acting at the interface with Cu to dissociate water. In the CO oxidation case, an enhancement in the dissociation of O₂ by the nanoparticles was a key factor. The strong interaction between CeOx nanoparticles and Cu(111) when preoxidized and reduced in CO resulted in a massive surface reconstruction of the copper substrate with the introduction of microterraces that covered 25-35% of the surface. This constitutes a new mechanism for surface reconstruction not observed before. These microterraces helped to facilitate a further enhancement of activity towards the WGS by opening an additional channel for the dissociation of water. In summary, inverse catalysts of CeOx/Cu(111) and CeO₂/Cu₂O/Cu(111) demonstrate the versatility of a model system to obtain insightful knowledge of catalytic processes. These systems will continue to offer a unique opportunity to probe key catalytic components and elucidate the relationship between structure and reactivity of novel materials and reactions in the future.

AN - 1443381294; 23775793 AB - The effects of diverse stresses on promoter selectivity and transcription regulation by the tumor suppressor p53 are poorly understood. We have taken a comprehensive approach to characterizing the human p53 network that includes p53 levels, binding, expression and chromatin changes under diverse stresses. Human osteosarcoma U2OS cells treated with anti-cancer drugs Doxorubicin (DXR) or Nutlin-3 (Nutlin) led to strikingly different p53 gene binding patterns based on chromatin immunoprecipitation with high-throughput sequencing experiments. Although two contiguous RRRCWWGYYY decamers is the consensus binding motif, p53 can bind a single decamer and function in vivo. Although the number of sites bound by p53 was six times greater for Nutlin than DXR, expression changes induced by Nutlin were much less dramatic compared with DXR. Unexpectedly, the solvent dimethylsulphoxide (DMSO) alone induced p53 binding to many sites common to DXR; however, this binding had no effect on target gene expression. Together, these data imply a two-stage mechanism for p53 transactivation where p53 binding only constitutes the first stage. Furthermore, both p53 binding and transactivation were associated with increased active histone modification histone H3 lysine 4 trimethylation. We discovered 149 putative new p53 target genes including several that are relevant to tumor suppression, revealing potential new targets for cancer therapy and expanding our understanding of the p53 regulatory network.

The retrieval of cloud, drizzle, and turbulence parameters using radar Doppler spectra is challenged by the convolution of microphysical and dynamical influences and the overall uncertainty introduced by turbulence. A new technique that utilizes recorded radar Doppler spectra from profiling cloud radars is presented here. The technique applies to areas in clouds where drizzle is initially produced by the autoconversion process and is detected by a positive skewness in the radar Doppler spectrum. Using the Gaussian-shape property of cloud Doppler spectra, the cloud-only radar Doppler spectrum is estimated and used to separate the cloud and drizzle contributions. Once separated, the cloud spectral peak can be used to retrieve vertical air motion and eddy dissipation rates, while the drizzle peak can be used to estimate the three radar moments of the drizzle particle size distribution. The technique works for nearly 50% of spectra found near cloud top, with efficacy diminishing to roughly 15% of spectra near cloud base. The approach has been tested on a large dataset collected in the Azores during the Atmospheric Radiation Measurement Program (ARM) Mobile Facility deployment on Graciosa Island from May 2009 through December 2010. Validation of the proposed technique is achieved using the cloud base as a natural boundary between radar Doppler spectra with and without cloud droplets. The retrieval algorithm has the potential to characterize the dynamical and microphysical conditions at cloud scale during the transition from cloud to precipitation. This has significant implications for improving the understanding of drizzle onset in liquid clouds and for improving model parameterization schemes of autoconversion of cloud water into drizzle.

Considering the need for improved quantitative precipitation forecasts, it is crucial that the cloud modeling community better understands the reasons for these differing conclusions and knows the relevance of these sensitivities for the numerical weather prediction. This study examines the role of environmental conditions and storm type on the sensitivity of precipitation simulations to the nature of the rimed ice species (graupel or hail). Idealized 3D simulations of supercells/multicells and squall lines have been performed in varying thermodynamic environments. It has been shown that for simulation periods of sufficient length (>2 h), graupel-containing and hail-containing storms produce domain-averaged surface precipitation that is more similar than many earlier studies suggest. While graupel is lofted to higher altitudes and has a longer residence time aloft than hail, these simulations suggest that most of this graupel eventually reaches the surface and the surface precipitation rates of hail- and graupel-containing storms converge. However, environmental conditions play an important role in the magnitude of this sensitivity. Storms in large-CAPE environments (typical of storms in the U.S. Midwest) are more sensitive than their low-CAPE counterparts (typical of storms in Europe) to the nature of the rimed ice species in terms of domain-average surface precipitation. Supercells/multicells are more sensitive than squall lines to the nature of the rimed ice species in terms of spatial precipitation distribution and peak precipitation, disregarding of the amount of CAPE.

These new data increase confidence about the predicted range of radioactive ballistic fragments that could endanger first responders and the public. The results of the most recent complete set of experiments indicate that the previously recommended initial hazard boundary corresponding to the potential for acute health effects can be reduced from 500 m to 250 m. This revised recommendation is independent of the total activity of the radioactive material. The assessment of the potential range and effects of dispersal from small particles as aerosol remains unchanged from the guidance issued in 2006. New recommendations are offered on sheltering versus evacuation and how to conduct the initial field measurements so as to make early decisions on protecting the public and responders, and providing coherent data for an assessment scientist to make a first estimate of the source term in the device.

AN - 1367881841; 23721080 AB - Using in situ liquid cell electron microscopy we investigate Pd growth in dilute aqueous Pd salt solutions containing Au nanoparticle seeds. Au-Pd core-shell nanostructures are formed via deposition of Pd(0), generated by the reduction of chloropalladate complexes by radicals, such as hydrated electrons (eaq(-)) induced by the electron beam in the solution. The size and shape of the Au seeds determine the morphology of the Pd shells, via preferential Pd incorporation in low-coordination sites and avoidance of extended facets. Analysis of the Pd incorporation on Au particles at different distances from a focused electron beam provides a quantitative picture of the growth process and shows that the growth is limited by the diffusion of eaq(-) in the solution.

The complexity and accuracy models of these components are suitable for evaluating the cloud transient impact on bulk power system. Of particular interest is the grid inertial response in situations such as for high penetration levels of solar generation and/or the fast cloud transient induced solar generation decrease coupled with outages that recurrently occur in the grid, e.g., a generator trip. The impact of such events on the grid frequency responses is investigated using a simplified simulation approach to account for the irradiance variation patterns. Responsive battery energy storage systems (BESSs) are recognized as an effective means to improve the inertial response, as investigated and demonstrated in this study.

Information from multiple sources shows that during the October 29, 2012 hurricane Sandy, virtually all PV systems received no damage by the storm and, if not disconnected, they produced electricity following the storm. The same was observed in previous disasters. In the aftermath of Hurricanes Katrina and Rita, PV systems were used to support the Gulf States' disaster response efforts. The Fukushima earthquake and tsunami destroyed three nuclear reactors causing "meltdown" and radiation releases, whereas the many thousands of PV roof-top arrays were left undamaged. These experiences show that PV systems, in addition to being environmentally benign, can also sustain extreme weather conditions like hurricanes, earthquakes and tsunamis.

Previous research in rodents has shown that exercise may attenuate the rewarding effects of drugs of abuse. The present study examined the effects of high and low exercise on cocaine responses in male Wistar rats that had been trained to self-administer and were compared to a group of sedentary rats. High exercise rats (HE) ran daily on a treadmill for 2h and low exercise (LE) ran daily for 1h. After 6 weeks of this exercise regimen, rats were tested over 2 days for reinstatement (day 1: cue-induced reinstatement; day 2: cocaine-primed reinstatement). During cue-induced reinstatement, the sedentary rats showed the expected increase in active lever responses when compared to maintenance, whereas these increased responses were inhibited in the exercised rats (HE and LE). During cocaine-primed reinstatement, however, there was a significant increase in active lever presses when compared to maintenance only in the HE group. This data suggests that chronic exercise during abstinence attenuates the cue-induced reinstatement seen in the sedentary rats by 26% (LE) and 21% (HE). In contrast, only the high exercise rats exhibited sensitized cocaine-seeking behavior (active lever presses) following cocaine-primed reinstatement. Finally, while sedentary rats increased locomotor activity during cocaine-primed reinstatement over that seen with cocaine during maintenance, this was not observed in the exercised rats, suggesting that exercise may interfere with the sensitized locomotor response during cocaine reinstatement.

Using X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HR-TEM), the ZrO (sub 2) were found to be 2-3 nm tetragonal crystalline nanoparticles. Strong interfacial interaction between the ZrO (sub 2) nanoparticles and the MWCNT surface was observed by near-edge X-ray absorption fine structure spectroscopy (NEXAFS) at the carbon K-edge and the oxygen K-edge, and this strong metal-oxide/support interaction through oxygen functionalities on the MWCNT surface leads to small ZrO (sub 2) particle size and thermal stability. The ZrO (sub 2) particle size can be well tuned by varying ZrO (sub 2) loading and annealing temperature, as studied by XRD, HR-TEM, in-situ small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS), and NEXAFS. Such materials can be turned into solid acid catalysts by sulfur impregnation (S-ZrO (sub 2) /MWCNT), which has potential applications in fuel cells and biomass processing.

We have determined the average concentrations of the following trace and minor elements in teeth from a variety of coastal and pelagic shark species: Fe, Cr, Co, Mn, Ba, Cu, Al, U, Pb, Ni, V, Zn, Mg, Ce, and Sr. The teeth analyzed were collected from the jaws of recently deceased individuals of the following species: Galeocerdo cuvier (tiger shark), Carcharhinus limbatus (black tip), Carcharias taurus (sand tiger), Carcharhinus leucas (bull shark), Prionace glauca (blue shark), Isurus oxyrinchus (mako shark), Carcharhinus brevipinna (spinner shark), Carcharhinus obscurus (dusky shark),and Hexanchus griseus (bluntnose six gill shark). Trace and minor element concentrations were measured using an ICP-MS; tooth enameloid ranged from <1 ppm for U, to 1000s of ppm for Sr. For individual sharks elemental concentrations in enameloid did not vary greatly from tooth to tooth in the functional tooth row, nor was there wide variation in concentration between teeth in functional and adjacent pre-functional tooth rows. The concentrations for each particular element in enameloid were generally similar from species to species, with some notable exceptions (e.g., relatively low Sr in Carcharhinus brevipinna). We interpret the general uniformity in composition of enameloid across species to mean that the life habits of the animals we tested and their food sources were sufficiently broad to have exposed our sharks to average conditions of oceanic chemistry. The elemental concentrations of modern shark teeth reported here provide base level values that allow for the detection of diagenetic changes in fossil shark tooth chemistry. These base values were also used as a basis to quantify total diagenetic change in Carcharias sp. teeth associated with the Cretaceous/Paleogene boundary on the New Jersey Coastal Plain. Carcharias sp. teeth were analyzed using Synchrotron microbeam X-ray fluorescence (SXRF) to quantify the Fe, Pb, Sr and U concentrations. Differences in the chemistry between modern and fossil teeth can reasonably be attributed to diagenetic changes. Detecting and quantifying such variations may prove helpful in improving the reliability of geochronological dates obtained for fossil shark teeth.

The formation of Mo sub(2)C is investigated by thermogravimetry and in situX-ray diffraction. X-ray absorption analysis reveals that Mo sub(2)C nanoparticles are inlaid or anchored into the carbon supports, and the electronic modification makes the surface exhibit a relatively moderate Mo-H bond strength. It is found that carbon nanotube-supported Mo sub(2)C showed superior electrocatalytic activity and stability in the hydrogen evolution reaction (HER) compared to the bulk Mo sub(2)C. An overpotential of 63 mV for driving 1 mA cm super(-2) of current density was measured for the nanotube-supported Mo sub(2)C catalysts; this exceeds the activity of analogous Mo sub(2)C catalysts. The enhanced electrochemical activity is facilitated by unique effects of the anchored structure coupled with the electronic modification.

However, direct evaluation of the parameterization schemes for these surface fluxes is rare due to limited observations. This study takes advantage of the long-term observations of surface fluxes collected at the Southern Great Plains site by the Department of Energy Atmospheric Radiation Measurement program to evaluate the six surface flux parameterization schemes commonly used in the Weather Research and Forecasting (WRF) model and three U.S. general circulation models (GCMs). The unprecedented 7-yr-long measurements by the eddy correlation (EC) and energy balance Bowen ratio (EBBR) methods permit statistical evaluation of all six parameterizations under a variety of stability conditions, diurnal cycles, and seasonal variations. The statistical analyses show that the momentum flux parameterization agrees best with the EC observations, followed by latent heat flux, sensible heat flux, and evaporation ratio/Bowen ratio. The overall performance of the parameterizations depends on atmospheric stability, being best under neutral stratification and deteriorating toward both more stable and more unstable conditions. Further diagnostic analysis reveals that in addition to the parameterization schemes themselves, the discrepancies between observed and parameterized sensible and latent heat fluxes may stem from inadequate use of input variables such as surface temperature, moisture availability, and roughness length. The results demonstrate the need for improving the land surface models and measurements of surface properties, which would permit the evaluation of full land surface models.

AN - 1273777529; 23252934 AB - We report chemical modification of self-assembled block copolymer thin films by ultraviolet light that enhances the block-selective affinity of organometallic precursors otherwise lacking preference for either copolymer block. Sequential precursor loading and reaction facilitate formation of zinc oxide, titanium dioxide, and aluminum oxide nanostructures within the polystyrene domains of both lamellar- and cylindrical-phase modified polystyrene-block-poly(methyl methacrylate) thin film templates. Near-edge X-ray absorption fine structure measurements and Fourier transform infrared spectroscopy show that photo-oxidation by ultraviolet light creates Lewis basic groups within polystyrene, resulting in an increased Lewis base-acid interaction with the organometallic precursors. The approach provides a method for generating both aluminum oxide patterns and their corresponding inverses using the same block copolymer template.

AN - 1273354714; 23244762 AB - Two-dimensional or ultrathin layered materials are attracting broad interest in both fundamental science and applications. While exfoliation can provide high-quality single- and few-layer flakes with nanometer to micrometer size, the development of wafer-scale synthesis methods is important for realizing the full potential of ultrathin layered materials. Here we demonstrate the growth of high quality few-layer boron nitride (BN) films with controlled thickness by magnetron sputtering of B in N(2)/Ar, a scalable process using only benign, nontoxic reagents. BN films up to two atomic layers are synthesized by reactive deposition at high substrate temperatures. Thicker monocrystalline BN films with an arbitrary number of atomic layers are achieved in a two-step process comprising cycles of alternating room temperature deposition and annealing. Tunneling transport across these BN films shows pinhole-free insulating behavior on μm(2) scales, demonstrating the realization of high quality ultrathin dielectrics.

A quarter century ago, the International Union of Pure and Applied Chemistry (IUPAC) recommended values for half-lives (decay constants) for a series of long-lived nuclides, many of which could be used for dating materials. The IUGS and the IUPAC recommendations differed in many cases. More than a decade ago, geochronologists began writing articles suggesting that updates should be made to the original IUGS recommendations because of the existence of more recent data on the original isotopic information that had been presented and because of the absence of any uncertainties that were associated with that data. A few years ago, an inter-Union Task Group of members of IUGS and IUPAC was formed to make 'Recommendations for Isotopic Data in the Geosciences' and was approved by their Executive Boards. The rationale was similar, there were new data now available and the associated uncertainties need to be added to all recommended values. The procedure for any recommendation of isotopic data would involve a re-evaluation of the measurement uncertainty budgets for each experiment, especially for the 'type-B' or non-statistical uncertainties, before combining the overall uncertainties and determining a recommended value. A number of isotopes will be discussed.

A combination of x-ray microscopy, elemental mapping and XANES spectroscopy at the K-absorption edge of sulfur was used to analyze the elemental and particulate composition of an urban soil loaded with debris from WWII, exemplary from Berlin, Germany. The goal was to specify and analyze the sulfur pool of soils with major anthropogenic impact, i.e. the dumping of war debris. This impact obviously influences soil composition and soil formation processes, but may, due to sulfate leaching, also be a substantial risk to urban water quality. The sulfur load of different debris components was studied and the sulfur content of different soil samples was evaluated and correlated to different parameters, such as position of the respective soil horizon within the soil profile or location of the soil profile in the surrounding terrain. With XANES spectroscopy, the averaged sulfur pool of whole soil horizons as well as of single debris components was studied. With X-ray fluorescence imaging and spectromicroscopy, soil aggregates, debris particles, and soil solution were analyzed on the micrometer and sub-micrometer scale. Different soil and debris constituents could be assigned to elemental distribution patterns within collected fluorescence maps, allowing for a detailed analysis of the sulfur pool and release from war debris in subsequent studies. These measurements show highly heterogeneous sample composition and clear gradients in sulfur speciation and oxidation state within single particles. The weathering of the anthropogenic material is therefore directly observable. A detailed understanding of this sulfur lixiviation is central to preserve urban water quality.

Although pore-scale mineral variation can profoundly affect fracture fluid flow [1] and the mass transfer of organics, metals and salts, major knowledge gaps exist due to the lack of experimental observations of pore-scale processes at fracture boundaries. We conducted core-flooding experiments with fractured carbonate-rich caprock samples and showed that while calcite dissolution is the primary geochemical driver of alterations to fracture geometry, permeability evolves based on a complex relationship between initial fracture geometry, mineral spatial heterogeneity and variation, fluid chemistry and flow rate [2]. To investigate the underlying causes of spatial variability of dissolution and fracture geometry alteration, we developed a new flow-through cell that enables 2D x-ray imaging of mineral-specific dissolution at a fracture surface. The parallel plate design provides an idealized fracture geometry to derive the relationship between flow rate, reaction rate, and mineral spatial heterogeneity and variation. In the flow-cell, a subsample of the carbonate-rich caprock core described above was reacted with acidified brine. The extent of dissolution was spatially correlated with calcite abundance relative to less soluble dolomite and silicate minerals, which is qualitatively consistent with the core-flooding experiment. In a second set of experiments with a limestone specimen, however, the extent of dissolution was not strictly correlated with the occurrence of calcite. Instead, the pattern and extent of dissolution suggested secondary causes such as calcite morphology, the presence of argillaceous minerals and other diagenetic features. These experimental results help define the combinations of brine chemistry, caprock mineralogy and flow rates with a high probability for geochemical alterations that increase fracture permeability.

Its unit-cell parameters were measured by in situ high-T powder X-ray diffraction up to 600 degrees C at ambient P. The T-V data were fitted with a polynomial expression for the volumetric thermal expansion coefficient (alpha (sub T) = a (sub 0) + a (sub 1) T), yielding a (sub 0) = 2.47(21) X 10 (super -5) K (super -1) and a (sub 1) = 1.45(36) X 10 (super -8) K (super -2) . Compression experiments at ambient T were conducted up to 10.40 GPa with a diamond-anvil cell combined with synchrotron X-ray radiation. A second-order Birch-Murnaghan equation of state was used to fit the P-V data, yielding K (sub T) = 97(3) GPa and V (sub 0) = 360.55(9) Aa (super 3) . These newly determined thermal expansion data and compression data were used to thermodynamically calculate the P-T curves of the following reactions: 2 sanidine (KAlSi (sub 3) O (sub 8) ) = wadeite (K (sub 2) Si (sub 4) O (sub 9) ) + kyanite (Al (sub 2) SiO (sub 5) ) + coesite (SiO (sub 2) ) and wadeite (K (sub 2) Si (sub 4) O (sub 9) ) + kyanite (Al (sub 2) SiO (sub 5) ) + coesite/stishovite (SiO (sub 2) ) = 2 hollandite (KAlSi (sub 3) O (sub 8) ). The calculated phase boundaries are generally consistent with previous experimental determinations.

AN - 1239056768; 23239355 AB - Clostridium botulinum neurotoxin is the most poisonous substance known to humans. It is a potential biowarfare threat and a public health hazard. The only therapeutics available is antibody treatment which will not be effective for post-exposure therapy. There are no drugs available for post-intoxication treatment. Accordingly, it is imperative to develop effective drugs to counter botulism. Available structural information on botulinum neurotoxins both alone and in complex with their substrates offers an efficient method for designing structure-based drugs to treat botulism.

These meteorites are usually connected to low albedo asteroid, which present visible/near-IR absorption explained by iron related absorption within phyllosilicates and oxides. In order to obtain quantitative insight into the mineralogy of iron-bearing phases, we have measured X-ray absorption near-edge spectroscopy at the iron K-edge of matrix from carbonaceous chondrites. This method enables to constrain the redox state and environment of iron in these meteorites. For this study, we selected seven CM chondrites and the CI Orgueil, expected to span a range of aqueous alteration degrees. Our analysis of the pre-edge features show that the redox state of Orgueil (CI) is dominated by octahedral Fe and that the Fe (super 3+) /(Fe (super 3+) + Fe (super 2+) ) atomic ratio is above 80%. Full-inversion of the spectra suggests that the iron budget is dominated by iron oxides, with additional contributions from phyllosilicate. In the case of the CM, the iron speciation appears different that in the case of Orgueil. Cronstedtite is identified from the inversion of the spectra, and suggested by the presence of significant amount of tetrahedral Fe (super 3+) . Within the CM chondrites, a trend of aqueous alteration appears presents, and which is roughly correlated to the scheme defined by Rubin et al. (2007). This trend is characterized by an increase in the amount of iron oxides. Two shock metamorphosed CM are present in our dataset (PCA 91008, WIS 91600). If WIS 91600 does not appear distinguishable, from the CM trend, in the case of PCA 91008, shock metamorphism did impact the pre-edge intensity and an increased amount of anhydrous silicates is found.

However, 2D imaging methods continue to offer complementary insights into processes controlling sub-grain scale variations in mineralogy and intragranular porosity that are often difficult to observe with 3D methods. For example, 2D imaging studies of mineral precipitation-induced changes in the pore network structure including detailed observations of distributions of secondary mineral precipitates can be coupled with 3D image analysis of a pore network to determine the pore properties required to infer permeability. In this work, the combined advantages of 2D and 3D imaging methods are highlighted through 3D X-ray Computed Microtomography (X-ray CT) and 2D Scanning Electron Microscopy (SEM) imaging of a reacted column experiment in the context of the Hanford, WA site and a sedimentary rock sample from the Alberta basin. Both samples were imaged using 3D X-ray CT imaging at a voxel resolution of 4 mu m and analyzed using 3DMA Rock to determine pore and throat size distributions as well as pore coordination numbers. Polished sections were then created from each sample and imaged using 2D SEM imaging with resolutions of 0.4 mu m for the reacted column and an order of magnitude larger for the sedimentary rock. 2D images were analyzed using an erosion dilation method to determine pore and throat size distributions that were then corrected using sample-specific bias correction factors. The permeability of each sample was predicted from pore network models informed with the 2D or 3D pore and throat size distributions and the coordination numbers determined from the 3D analysis. Differences in 2D and 3D image resolutions resulted in over- or under-estimating small pore throats and led to predicted permeabilities that differed by orders of magnitude. For both samples, higher resolution images resulted in over-estimating small pore throats and under-estimating expected permeability. While higher resolution images are generally favored, they may not improve predictions of permeability as they require additional processing to distinguish small flow-conducting pore throats from surface roughness features. While 3D imaging is required to determine the network coordination, 2D imaging is necessary to understand where secondary minerals precipitate within the pore network and to quantify sub-grain scale variations. These advantages are demonstrated through SEM imaging of polished sections from the reacted column experiment. 2D images revealed that secondary mineral precipitates occurred as a relatively uniform coating on grain surfaces, unrelated to mineralogy, pore size, or other factors. SEM images also revealed new observations of sub-grain scale variations that showed that Hanford sand grains have a high amount of intragranular porosity and mineral precipitates formed in intragranular regions. These observations, which are important to understanding the reactive system, could not have been made if 3D imaging was used exclusively.

The caustic wastes leachate induces primary mineral dissolution (releasing Si) and subsequent secondary precipitation (feldspathoids, such as sodalite and cancrinite) in the sediments. The dissolution-precipitation reactions affect the transport of radioactive elements (90Sr and 137Cs) in the sub-surface through changing the morphology of the sediments. We studied here the changes of the morphology of the sediments caused by exposure of quartz sand or Hanford sediments to simulated tank waste leachates (2 M Na+, 1 M OH-, 1.053 M NO3-, 0.05 M Al3+ and 10-5 M Sr2+) using a series of steady-state-flow saturated column experiments. The 3D structures were determined using synchrotron computed microtomography (CMT) at the National Synchrotron Light Source. Sequential measurements were made at intervals over an exposure time of up to approximately 620 days with a pixel size of 4 mu m in mini columns (ID2.1 mm) packed with quartz sand, or with a pixel size of 11 mu m in intermediate size columns (ID19 mm) packed with Hanford sediments. Values for porosity as a function of treatment time were obtained showing major changes. Good agreement was found between the microstructure porosity determinations with results obtained from measurements on the composition of the treatment fluids. The results also show the changes in the three dimensional morphology of the sediment structures as a function of the treatment time. Good agreement was also found between observed and simulated porosity and aqueous chemistry obtained using the reactive transport simulator STOMP. A comparison of the CMT results with complementary high-resolution scanning electron microscopy scans will also be presented.

The mainstream approach to tackle this complex system relies on earth system modeling (ESM) that is based on various conservation principles (e.g., conservation of energy, mass and momentum), breaks the Earth system into ever smaller units, and includes ever more processes. Despite the great progress over the last few decades, the bottom-up ESM approach still suffers from many deficiencies such as highly uncertain climate sensitivity and cloud feedbacks. This study explores a new theoretical framework that treats the Earth system as a whole and seeks entropy-based principles in addition to those conservation principles (e.g., energy conservation). In particular, we show that even at steady state, radiation entropy is highly imbalanced with the outgoing longwave radiation carrying much more radiation entropy than the incoming solar radiation, and that the Earth system as a whole works to maximize the radiation entropy imbalance by building close connection between incoming shortwave and outgoing longwave radiation. The entropy-based theory provides a possible explanation of why the Earth albedo varies around 0.3 during the Holocene.

In most bacterial systems, the periplasmic component is the primary determinant of specificity of the transport complex as a whole. Here, the X-ray crystal structure of a periplasmic glucose-binding protein (GBP) from Thermotoga maritima determined at 2.4Aa resolution is reported. The molecule consists of two similar alpha / beta domains connected by a three-stranded hinge region. In the current structure, a ligand ( beta -D-glucose) is buried between the two domains, which have adopted a closed conformation. Details of the substrate-binding sites revealed features that determine substrate specificity. In toto, ten residues from both domains form eight hydrogen bonds to the bound sugar and four aromatic residues (two from each domain) stabilize the substrate through stacking interactions.

Therefore, we studied soils on a mofette site in the Czech Republic at three spots differing in the partial pressures of soil CO (sub 2) (p(CO (sub 2) )=0.04, 1, and 1). We recorded 69 Fe K-XANES spectra in 5 regions of interest on 3 thin sections in fluorescence mode. Iron was enriched in filled pores, e.g., former root channels. Generally, most of the Fe was identified in different clay minerals (smectites, illites and chlorites). Minor pedogenic Fe contributors were ferrihydrite, green rust, magnetite, maghemite, vivianite and siderite, whereas typical soil Fe (hydr)oxides such as goethite, hematite or lepidocrocite were never doubtlessly identified. The Fe(II)-containing minerals were particularly detected at p(CO (sub 2) )=1 indicating an effect of soil CO (sub 2) on the formation of secondary Fe phases. Organic Fe complexes were less important, and their formation seemed to be inhibited at p(CO (sub 2) )=1. We thus conclude that geogenic CO (sub 2) affects pedogenesis and causes quantitative and qualitative variations of Fe speciation. Abstract Copyright (2012) Elsevier, B.V.

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.

Such nano-scale morphological description of these high-specific-surface-area compounds show promise for improved understanding of soils, sediments or groundwater aquifers. However, present high-quality X-ray microscopes are located at synchrotron radiation facilities resulting in limited applicability and accessibility for colloid scientists. Here we investigate the applicability of a laboratory-scale transmission X-ray microscope for studies of colloids of the environment. The microscope is based on a laser-plasma source in combination with multilayer and zone plate optics. Samples are held at atmospheric pressure in their natural wet state. We show images revealing the nano-scale morphology of the clay nontronite, soils such as chernozem and luvisol, and the mineral hematite, an iron oxide. Comparative studies of dried substances clearly show the need for imaging in the wet state. The image quality approaches that of synchrotron-based microscopes, albeit at longer exposure times. Stereo imaging is investigated as a means for giving 3D information with shorter exposure times than tomography requires. Finally the future development of the laboratory X-ray microscope is discussed, especially with regard to the reduction of exposure times. Abstract Copyright (2012) Elsevier, B.V.

The original Cu nanoparticles, approximately 30nm in diameter, were composed of Cu(I) and Cu(II) species, presumably a Cu(I) core surrounded by oxidized Cu(II). When the Cu nanoparticles were initially added to the biofilm, Cu nanoparticles were occasionally found as individual particles but most frequently were observed as aggregates. The aggregates were in association with diatoms and the extracellular polymeric substances (EPS) of the biofilm. In addition, a new Cu(II) species, as evident from a shift in its peak position (-0.4eV) relative to the Cu nanoparticles, was found to be sorbed by the diatoms after 5 min and was still detected after 7 days. Evidently, the Cu nanoparticles had undergone dissolution, followed by sorption of ionic Cu(II) by the diatoms. The bacteria and cyanobacteria in the biofilm did not apparently sorb detectable amounts of Cu at any time. C 1s measurements indicated that the Cu(II) from solution was sorbed by the lipid-rich extracellular polymeric substances associated with the diatoms. These observations demonstrated that both the Cu nanoparticles and dissolution products remained associated with the river biofilm through interactions with specific biopolymers up to 7 days following exposure. Therefore, for some metal nanomaterials, sorption of the solid phase with subsequent dissolution and re-sorption are significant with respect to their chemodynamics and effects on the biofilm, especially when trophic transfer events are considered. Importantly, these interactions provide an entry point for copper into the aquatic food web. Abstract Copyright (2012) Elsevier, B.V.

In these settings, particles of ZnS are formed in the presence of natural organic acids such as humic substances, proteins and other biomolecules that will interfere with cluster growth and aggregation kinetics. Thiol-containing organics such as cysteine are capable of adsorbing to clusters and nanoparticles of metal sulfides as they precipitate from solution. The thiols induce electrostatic repulsive forces at particle interfaces resulting in slow aggregation rates. The aim of this work was to investigate how cysteine influences the nucleation and growth rate of ZnS during early stages (less than one day) of precipitation. Results from time-resolved small angle X-ray scattering and dynamic light scattering confirmed that cysteine altered the ZnS precipitation process by decreasing aggregation rates of polynuclear ZnS clusters (smallest size <1 nm). Furthermore, with decreased aggregation between clusters induced by cysteine, the growth rates of the nanoclusters appeared to increase. Characterization of the precipitation products by Zn extended X-ray absorption spectroscopy also indicated that an excess of cysteine relative to ZnS resulted in larger subunits compared to mixtures with equimolar quantities of cysteine and ZnS. Overall these results provide clues toward the mechanism by which natural organic ligands interfere with the ZnS precipitation process in sediments and enable nanoscale clusters or particles to persist.

Along with information about atomic arrangements, the diffraction pattern arising from a collection of nanoparticles contains information on the grain size, shape and defect structure and cannot simply be treated as a broadened collection of Bragg peaks. The Debye equation, a sum over all pairs of atoms in the particle, calculates the scattering at each value of Q, rather than at discrete values of hkl. Especially when atomic arrangements are well known, modeling using the Debye equation allows the refinement of particle shape, allowing the investigation of dominant growth axes. We show the example of 6-line ferrihydrite, fitting the diffraction pattern using a disc of 2.3(1)nm in the ab plane and 6(2)nm along the c axis. A powerful and intuitive way to help examine the diffraction pattern is to take the Fourier transform of the normalized total scattering (Bragg and diffuse), giving the pair distribution function (PDF). The PDF represents a bond length distribution of the material weighted by the respective scattering powers of the contributing atoms. Using examples from the literature, we show that by analyzing the medium range correlations ( approximately 5-15A), the structure of a nanoparticle can be distinguished using PDFs generated from model structures.

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.

Significantly shorter induction times for the ferrihydrite formation have been macroscopically observed in the presence of chlorite particles, thus indicating heterogeneous nucleation as a major precipitation mechanism. A combination of Scanning Electron Microscopy (SEM) and Scanning Transmission X-Ray microscopy (STXM) on the O K-edge and Fe L-edge was used to clearly distinguish ferric iron precipitates from chlorite and to obtain the spatial distribution of iron precipitates on the chlorite surface under conditions of homogenous and heterogeneous formation. Oxygen K-edge results show the precipitation of a highly hydrolyzed chlorite surface associated ferric iron phase under heterogeneous conditions. Precipitates with different oxygen K-edge features are observed on the chlorite basal faces compared to the edge surfaces which can be attributed to cluster size effects and differences in the O/OH ratio. The results obtained from iron L-edge XANES corroborate the observations of the oxygen K-edge, indicating a thin surface layer of ferric iron precipitates and preferential precipitation at the chlorite edge surfaces. Under conditions where homogeneous ferrihydrite formation dominates, beside surface coatings separate iron colloids/nanoparticles are observed. Iron L-edge analysis and the pre-edge splitting on the oxygen K-edge indicate a higher long-range order/lower hydration comparable to ferrihydrite reference spectra. The results show that the Fe(III) secondary phase formation as surface coating or nanoparticles and their spatial distribution depends on the degree of supersaturation. These observations may have direct consequences for the retention and mobility of various contaminants in aquifer systems and potential remediation strategies.

Although the electrical output of an individual SMR is relatively small compared to that of typical commercial nuclear plants, they can be grouped to produce as much energy as a utility demands. Furthermore, SMRs can be used for other purposes, such as producing hydrogen and generating process heat.

Three sensitivity experiments were applied to two composites of 15 convective and 15 frontal stratiform intense precipitation events observed in a coastal midlatitude region (Belgium), which were evaluated against satellite-retrieved cloud properties and radar-rain-gauge derived surface precipitation. It is found that the cloud optical thickness distribution was well captured by all experiments, although a significant underestimation of cloudiness occurred in the convective composite. The cloud-top-pressure distribution was improved most by more realistic snow size distributions (including a temperature-dependent intercept parameter and non-spherical snow for the calculation of the slope parameter), due to increased snow depositional growth at high altitudes. Surface precipitation was far less sensitive to whether graupel or hail was chosen as the rimed ice species, as compared to previous idealized experiments. This smaller difference in sensitivity could be explained by the stronger updraught velocities and higher freezing levels in the idealized experiments compared to typical coastal midlatitude environmental conditions.

The Upper Peter mineralization consists of native Au in quartz-carbonate veins with 1 wt.% sulfides dominated by pyrite and arsenopyrite although stibnite, the primary Sb-bearing sulfide mineral, can be locally significant. Dissolved Sb concentrations can reach up to 349 mu g L (super -1) in the mine pool. Sediments were collected for detailed geochemical and mineralogical characterization at locations along the 350-m flow path, which includes a 100-m shallow channel within the adit, a sediment settling pond about 45 m beyond the adit portal and an open wetland another 120 m farther downstream. From the mine pool to the wetland outlet, dissolved Sb in the drainage drops from 199 mu g L (super -1) to below the detection limit due to the combined effect of dilution and removal from solution. Speciation analyses using X-ray absorption near-edge structure (XANES) spectroscopy indicate that Sb(III)-S accounts for around 70% of total Sb in the sediments in the main pool at the far end of the adit. At a short distance (24 m) downstream of the main adit pool, however, Sb(III)-O and Sb(V)-O species represent > or =50% of total Sb in the bulk sediments, indicating significant oxidation of the primary sulfides inside the adit. Although Sb appears largely oxidized in the bulk samples collected near the portal, Sb(III)-S species are nevertheless present in the <53-mu m fraction, suggesting a higher oxidation rate for stibnite in the coarser grains, possibly due to galvanic interaction with pyrite. Secondary Sb species released from the sulfide oxidation are most likely sorbed/co-precipitated with Fe-, Mn-, and Al-oxyhydroxides along the flow channel in the adit and in the sediment settling pond, with the Fe phase being the dominant sink for Sb.

At pH 5, with an applied potential of -0.96 V vs. NHE (overpotential of -0.55 V), the complexes are highly efficient, having both high rate constants and Faradaic efficiencies (F.E.s) for the selective reduction of CO sub(2) to CO. When the pH is below the pK sub(a) (pH < 2) of the Ni(H) species (pK sub(a)s: 0.5-2), the F.E.s are still high but product selectivity changes to yield predominantly H sub(2) from the reduction of water. At least two of the complexes investigated are better electrocatalysts than [Ni(cyclam)] super(2+), probably due to: (i) surface geometries that are suitable for adsorption onto the mercury electrode surface, and (ii) electronic effects of methyl groups or cyclohexane rings on the cyclam backbone. Mechanistic studies by pulse radiolysis show evidence of Ni(CO sub(2)) adducts for two of the catalysts, with K sub(C)O sub(2) similar to 10 M super(-1) for the reaction of Ni super(I) with CO sub(2) in aqueous solution.

We predicted a negative relationship between age and the amount of value placed on self-esteem boosts. We also investigated the correlates of liking versus wanting self-esteem boosts (and other pleasant rewards) on depression. A nationally representative sample of American adults (N = 867) indicated how much they liked and wanted several pleasant rewards (i.e., sex, food, alcohol, money, friendship, self-esteem boost). They also completed a standardized measure of depressive symptoms. As expected, there was a negative relationship between age and valuing self-esteem boosts, sex, and alcohol. People with depressive symptoms wanted self-esteem boosts, even though they did not like them very much. Similar effects were obtained for depressive symptoms and alcohol and friendship. This is the first research to show that self-esteem boosts are more valued among a nationally representative sample of younger American adults. It also is the first research to explore the association between depression and the motivation to boost self-esteem. People with depressive symptoms want self-esteem, and may pursue it, but this pursuit may feel unrewarding because they do not derive pleasure from it.

However, the extent to which striatal DA function in METH predicts recovery has not been evaluated. Here we assessed whether striatal DA activity in METH abusers is associated with clinical outcomes. Brain DA D2 receptor (D2R) availability was measured with positron emission tomography and [ super(11)C]raclopride in 16 METH abusers, both after placebo and after challenge with 60 mg oral methylphenidate (MPH) (to measure DA release) to assess whether it predicted clinical outcomes. For this purpose, METH abusers were tested within 6 months of last METH use and then followed up for 9 months of abstinence. In parallel, 15 healthy controls were tested. METH abusers had lower D2R availability in caudate than in controls. Both METH abusers and controls showed decreased striatal D2R availability after MPH and these decreases were smaller in METH than in controls in left putamen. The six METH abusers who relapsed during the follow-up period had lower D2R availability in dorsal striatum than in controls, and had no D2R changes after MPH challenge. The 10 METH abusers who completed detoxification did not differ from controls neither in striatal D2R availability nor in MPH-induced striatal DA changes. These results provide preliminary evidence that low striatal DA function in METH abusers is associated with a greater likelihood of relapse during treatment. Detection of the extent of DA dysfunction may be helpful in predicting therapeutic outcomes.

AN - 1028023047; 22801721 AB - The possibility of generating MgH(2) nanoparticles from Grignard reagents was investigated. To this aim, five Grignard compounds, i.e. di-n-butylmagnesium, tert-butylmagnesium chloride, allylmagnesium bromide, m-tolylmagnesium chloride, and methylmagnesium bromide were selected for the potential inductive effect of their hydrocarbon group in leading to various magnesium nanostructures at low temperatures. The thermolysis of these Grignard reagents was characterised in order to determine the optimal conditions for the formation of MgH(2). In particular, the use of di-n-butylmagnesium was found to lead to self-assembled and stabilized nanocrystalline MgH(2) structures with an impressive hydrogen storage capacity, i.e. 6.8 mass%, and remarkable hydrogen kinetics far superior to that of milled or nanoconfined magnesium. Hence, it was possible to achieve hydrogen desorption without any catalyst at 250 °C in less than 2 h, while at 300 °C, hydrogen desorption took only 15 min. These superior performances are believed to result from the unique physical properties of the MgH(2) nanocrystalline architecture obtained after hydrogenolysis of di-n-butylmagnesium.

AN - 1023533553; 22733161 AB - We have investigated surface CO oxidation on "inverse catalysts" composed of SnO(x) nanostructures supported on Pt(111) using X-ray photoelectron spectroscopy (XPS), low-energy ion scattering spectroscopy (LEISS) and temperature-programmed desorption (TPD). Nanostructures of SnO(x) were prepared by depositing Sn on Pt(111) pre-covered by NO(2) layers at low temperatures. XPS data show that the SnO(x) nanoparticles are highly reduced with Sn(II)O being the dominant oxide species, but the relative concentration of Sn(II) in the SnO(x) nanoparticles decreases with increasing Sn coverage. We find that the most active SnO(x)/Pt(111) surface for CO oxidation has smallest SnO(x) coverage. Increasing the surface coverage of SnO(x) reduces CO oxidation activity and eventually suppresses it altogether. The study suggests that reduced Sn(II)O, rather than Sn(IV)O(2), is responsible for surface CO oxidation. The occurrence of a non-CO oxidation reaction path involving reduced Sn(II)O species at higher SnO(x) coverages accounts for the decreased CO oxidation activity. From these results, we conclude that the efficacy of CO oxidation is strongly dependent on the availability of reduced tin oxide sites at the Pt-SnO(x) interface, as well as unique chemical properties of the SnO(x) nanoparticles.

The increase in heat content of the world ocean, obtained as the average of several recent compilations, is found to be linearly related to the increase in global temperature over the period 1965-2009; the slope, augmented to account for additional heat sinks, which is an effective heat capacity of the climate system, is 21.8 + or - 2.1 W year m (super -2) K (super -1) (one sigma), equivalent to the heat capacity of 170 m of seawater (for the entire planet) or 240 m for the world ocean. The rate of planetary heat uptake, determined from the time derivative of ocean heat content, is found to be proportional to the increase in global temperature relative to the beginning of the twentieth century with proportionality coefficient 1.05 + or - 0.06 W m (super -2) K (super -1) . Transient and equilibrium climate sensitivities were evaluated for six published data sets of forcing mainly by incremental greenhouse gases and aerosols over the twentieth century as calculated by radiation transfer models; these forcings ranged from 1.1 to 2.1 W m (super -2) , spanning much of the range encompassed by the 2007 assessment of the Intergovernmental Panel on Climate Change (IPCC). For five of the six forcing data sets, a rather robust linear proportionality obtains between the observed increase in global temperature and the forcing, allowing transient sensitivity to be determined as the slope. Equilibrium sensitivities determined by two methods that account for the rate of planetary heat uptake range from 0.31 + or - 0.02 to 1.32 + or - 0.31 K (W m (super -2) ) (super -1) (CO (sub 2) doubling temperature 1.16 + or - 0.09-4.9 + or - 1.2 K), more than spanning the IPCC estimated "likely" uncertainty range, and strongly anticorrelated with the forcing used to determine the sensitivities. Transient sensitivities, relevant to climate change on the multidecadal time scale, are considerably lower, 0.23 + or - 0.01 to 0.51 + or - 0.04 K (W m (super -2) ) (super -1) . The time constant characterizing the response of the upper ocean compartment of the climate system to perturbations is estimated as about 5 years, in broad agreement with other recent estimates, and much shorter than the time constant for thermal equilibration of the deep ocean, about 500 years.

Emphasis is placed on the state of understanding of Earth's energy flows and their susceptibility to perturbations, with particular emphasis on the roles of clouds and aerosols. More accurate measurements of the total solar irradiance and the rate of change of ocean enthalpy help constrain individual components of the energy budget at the top of the atmosphere to within + or -2 W m (super -2) . The measurements demonstrate that Earth reflects substantially less solar radiation and emits more terrestrial radiation than was believed even a decade ago. Active remote sensing is helping to constrain the surface energy budget, but new estimates of downwelling surface irradiance that benefit from such methods are proving difficult to reconcile with existing precipitation climatologies. Overall, the energy budget at the surface is much more uncertain than at the top of the atmosphere. A decade of high-precision measurements of the energy budget at the top of the atmosphere is providing new opportunities to track Earth's energy flows on timescales ranging from days to years, and at very high spatial resolution. The measurements show that the principal limitation in the estimate of secular trends now lies in the natural variability of the Earth system itself. The forcing-feedback-response framework, which has developed to understand how changes in Earth's energy flows affect surface temperature, is reviewed in light of recent work that shows fast responses (adjustments) of the system are central to the definition of the effective forcing that results from a change in atmospheric composition. In many cases, the adjustment, rather than the characterization of the compositional perturbation (associated, for instance, with changing greenhouse gas concentrations, or aerosol burdens), limits accurate determination of the radiative forcing. Changes in clouds contribute importantly to this adjustment and thus contribute both to uncertainty in estimates of radiative forcing and to uncertainty in the response. Models are indispensable to calculation of the adjustment of the system to a compositional change but are known to be flawed in their representation of clouds. Advances in tracking Earth's energy flows and compositional changes on daily through decadal timescales are shown to provide both a critical and constructive framework for advancing model development and evaluation.

We present the current status of lattice-QCD weak matrix element calculations needed to obtain the elements and phase of the Cabibbo-Kobayashi-Maskawa (CKM) matrix and to test the Standard Model in the quark-flavor sector. We then discuss evidence that may hint at the presence of new physics beyond the Standard Model CKM framework. Finally, we discuss two opportunities where we expect lattice QCD to play a pivotal role in searching for, and possibly discovery of, new physics at upcoming high-intensity experiments: rare decays and the muon anomalous magnetic moment. The next several years may witness the discovery of new elementary particles at the Large Hadron Collider (LHC). The interplay between lattice QCD, high-energy experiments at the LHC, and high-intensity experiments will be needed to determine the underlying structure of whatever physics beyond-the-Standard Model is realized in nature.

Selective dissolution of spoil samples in combination with solid phase characterization using microbeam X-ray absorption near edge structure (mu XANES) spectroscopy and microbeam X-ray fluorescence (mu XRF) mapping were used to assess As associations in spoils ten years after CZA treatment. The results show that As preferentially associates with poorly crystalline Fe-oxyhydroxides as opposed to crystalline Fe-(oxyhydr)oxide phases. The crystalline Fe(III)-phases dominated in the treated spoil and exceeded those of the untreated spoil three-fold, but only 2.6-6.8% of total As was associated with this fraction. Correlation maps of As:Fe reveal that As in the CZA-treated spoils is primarily contained in surface coatings as precipitates and sorbates. Arsenic binding with poorly crystalline Fe-oxyhydroxides did not inhibit As uptake by plants. Abstract Copyright (2012) Elsevier, B.V.

Carbonate carbon isotope values shifted toward positive before the end of the Permian period and then shifted negative above the PTB into the Triassic period. Molecular carbon isotope values of biomarkers followed the same trend at and below the PTB and remained negative in the Triassic layer. These biomarkers were acyclic isoprenoids, ranging from C (sub 15) to C (sub 40) , steranes (C (sub 27) dominates) and terpenoids that were all significantly more abundant in samples from the Permian layer than those from the Triassic layer. The Triassic layer was distinguished by the dominance of higher molecular weight (waxy) n-alkanes. Stable carbon isotope values of individual components, including n-alkanes and acyclic isoprenoids such as phytane, isop-C (sub 25) , and squalane, are depleted in delta (super 13) C by up to 8-10 ppm in the Triassic samples as compared to the Permian. Measured molecular and isotopic variations of organic matter in the PT layers support the generally accepted view of Permian oceanic stagnation followed by a massive upwelling of toxic deep waters at the PTB. A series of large-scale (global) outgassing events may be associated with the carbon isotope shift we measured. This is also consistent with the lithological evidence we observed of white thin-clay layers in this region. Our findings, in context with a generally accepted stagnant Permian ocean, followed by massive upwelling of toxic deep waters might be the major causes of the largest global mass extinction event that occurred at the Permian-Triassic boundary.

Concretions represent approximately 8% of the sediment by mass ( approximately 7% by volume), are irregularly distributed and have a near-normal size distribution with a mean diameter of 1.53 mm and graphic standard deviation of 0.64 mm. X-ray diffraction (XRD) and attenuated total reflectance (ATR) spectroscopy indicate that the concretions are composed of ambient sediments: quartz, montmorillonite, and feldspar, and a minor phosphatic phase that is also implied by geochemistry; however, the concretions preferentially exclude coarser grain sizes, and are cemented by hematite and goethite. Optical observations and synchrotron X-ray fluorescence (XRF) chemical mapping indicate that concretions are massive to weakly zoned with respect to hematitic cements. Compared to the surrounding sediments, concretion rare earth elements (REE) are elevated in total abundances, exhibit light rare earth element (LREE)-enrichment, and possess negative Ce-anomalies; Th/U ratios are lower due to elevated U. Mass balance calculations indicate that approximately 20% of the concretions are composed of iron oxides and that approximately 30 mm (super 3) of ambient sediment is required to provide the hematitic cement in a single 1.5 mm diameter concretion. Element mobility during concretion formation was tested assuming different immobile elements (Al, Ti, Zr). Assuming Zr immobility provides intermediate results, and indicates the following gains in concretions: Pb (572%), Fe (322%), Mn (142%), REE (438-116%), V (138%), U (124%), Ni (84%), and Nb (58%); other elements show either gains or losses of less than + or -50%. Ce-anomalies, low Th/U, and elevated V and U abundances point to a significant redox influence on element distributions in the concretions. High iron content, crude internal concentric banding, and redox controls suggest that the concretions are formed in seasonally variable, but generally moist, soil conditions with annual precipitation >130 cm. Trace element enrichment patterns are broadly consistent with derivation from downward percolating weathering fluids. Although the New Haven Arkose pedogenic concretions have significant differences and were clearly formed by different mechanisms than hematitic spherules discovered on Mars, they nevertheless exhibit a number of textural (e.g., sphericity, size distributions) and geochemical (e.g., Ni enrichments) similarities that support models suggesting that the Martian spherules are formed as sedimentary concretions.

AN - 1009540389; 22488413 AB - Synthetic DNA nanostructures are most commonly held together via Holliday junctions. These junctions allow for a wide variety of different angles between the double helices they connect. Nevertheless, only constructs with a very limited selection of angles have been built, to date, because of the computational complexity of identifying structures that fit together with low strain at odd angles. I have developed an algorithm that finds over 95% of the possible solutions by breaking the problem down into two portions. First, there is a problem of how smooth rods can form triangles by lying across one another. This problem is easily handled by numerical computation. Second, there is the question of how distorted DNA double helices would need to be to fit onto the rod structure. This strain is calculated directly. The algorithm has been implemented in a Mathematica 8 notebook called Holliday Triangle Hunter. A large database of solutions has been identified. Additional interface software is available to facilitate drawing and viewing models.

To do so, the sensitivity of surface precipitation is evaluated in two-dimensional idealized squall-line simulations with respect to the level of complexity in the bulk microphysics schemes of H. Morrison et al. and of J. A. Milbrandt and M. K. Yau. Factors examined include the number of predicted moments for each of the precipitating hydrometeors, the number and nature of ice categories, and the conversion term formulations. First, it is shown that simulations of surface precipitation and cold pools are not only a two-moment representation of rain, as suggested by previous research, but also by two-moment representations for all precipitating hydrometeors. Cold pools weakened when both rain and graupel number concentrations were predicted, because size sorting led to larger graupel particles that melted into larger raindrops and caused less evaporative cooling. Second, surface precipitation was found to be less sensitive to the nature of the rimed ice species (hail or graupel). Production of hail in experiments including both graupel and hail strongly depends on an unphysical threshold that converts small hail back to graupel, indicating the need for a more physical treatment of the graupel-to-hail conversion. Third, it was shown that the differences in precipitation extremes between the two-moment microphysics schemes are mainly related to the treatment of drop breakup. It was also shown that, although the H. Morrison et al. scheme is dominated by deposition growth and low precipitation efficiency, the J. A. Milbrandt and M. K. Yau scheme is dominated by riming processes and high precipitation efficiency.

While drills and exercises are highly effective tools in rehearsing for an emergency, the accidents at the Fukushima Daiichi Nuclear Power Plants presented real-world complexities that are difficult or impossible to simulate in such training. Customarily, the modeled hypothetical event used to create a drill or exercise data set is simple, well defined, and closely resembles conventional assumptions about the type of that event Consequently, the modeling performed by players from the outset closely resembles the planner's hypothetical event. This approach also entails idealized, uniform data in the simulated plume and ground deposition scenarios created for the drill that match the modeling closely. The real-world event that occurred in Japan sharply deviated from the simple picture ordinarily created for drills and exercises that typically involve a release of radioactivity that is of short duration, a single puff with constant meteorology, or simple deviation such as a wind shift to bifurcate the plume. In the very early stages, accurate plume and deposition model predictions were difficult to produce due to the lack of field monitoring data and other information. In contrast to drills and exercises where plant monitoring data is available, there was much less plant monitoring data, essentially no reactor state information, and the meteorological conditions and releases were much more complex. Inevitably, the measurements in Japan were not homogeneous, thus presenting technical challenges to assessors tasked with ensuring the quality of the finished assessments and data products for government officials, the responder community, and the public. In this paper, examples of some operational real-world complexities are considered. Procedures, measurements, or radiological assessments from the Fukushima response are not in the purview of this paper.

AN - 1009540552; 22525749 AB - Clostridium botulinum neurotoxins are classified as Category A bioterrorism agents by the Centers for Disease Control and Prevention (CDC). The seven serotypes (A-G) of the botulinum neurotoxin, the causative agent of the disease botulism, block neurotransmitter release by specifically cleaving one of the three SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins and induce flaccid paralysis. Using a structure-based drug-design approach, a number of peptide inhibitors were designed and their inhibitory activity against botulinum serotype A (BoNT/A) protease was determined. The most potent peptide, RRGF, inhibited BoNT/A protease with an IC(50) of 0.9 µM and a K(i) of 358 nM. High-resolution crystal structures of various peptide inhibitors in complex with the BoNT/A protease domain were also determined. Based on the inhibitory activities and the atomic interactions deduced from the cocrystal structures, the structure-activity relationship was analyzed and a pharmacophore model was developed. Unlike the currently available models, this pharmacophore model is based on a number of enzyme-inhibitor peptide cocrystal structures and improved the existing models significantly, incorporating new features.

AN - 1001956201; 22473590 AB - Plasmonics and photonics demand new methods for the controlled construction of nanoparticle (NP) arrays. Complex, low-symmetry configurations of DNA-functionalized NPs are obtained by connection to scaffolds of branched and folded DNA nanostructures. However, the stabilization of these branched structures by Mg(2+) counterions also drives the uncontrolled aggregation of NPs. We demonstrate, using a two-dimensional DNA scaffold, that derivatizing gold nanoparticles (AuNPs) with zwitterionic ligands overcomes this problem.

Novel data analysis methods were developed, de-coupling for the first time the size and time-dependence of particle growth rates by fitting the aerosol general dynamic equation to size distributions obtained at an instant in time. Size distributions of freshly nucleated total aerosol (neutral and charged) were measured during two intensive measurement campaigns in different environments (Atlanta, GA and Boulder, CO) using a recently developed electrical mobility spectrometer with a diethylene glycol-based ultrafine condensation particle counter as the particle detector. One new particle formation (NPF) event from each campaign was analyzed in detail. At a given instant in time during the NPF event, size-resolved growth rates were obtained directly from measured size distributions and were found to increase approximately linearly with particle size from ~1 to 3 nm geometric diameter, increasing from 5.5 +/- 0.8 to 7.6 +/- 0.6 nm h super(-1) in Atlanta (13:00) and from 5.6 +/- 2 to 27 +/- 5 nm h super(-1) in Boulder (13:00). The resulting growth rate enhancement Gamma , defined as the ratio of the observed growth rate to the growth rate due to the condensation of sulfuric acid only, was found to increase approximately linearly with size from ~1 to 3 nm geometric diameter. For the presented NPF events, values for Gamma had lower limits that approached ~1 at 1.2 nm geometric diameter in Atlanta and ~3 at 0.8 nm geometric diameter in Boulder, and had upper limits that reached 8.3 at 4.1 nm geometric diameter in Atlanta and 25 at 2.7 nm geometric diameter in Boulder. Nucleated particle survival probability calculations comparing the effects of constant and size-dependent growth indicate that neglecting the strong dependence of growth rate on size from 1 to 3 nm observed in this study could lead to a significant overestimation of CCN survival probability.

This work examines changes in pore structure due to these reactions in a previously-conducted column experiment. The column was sectioned and 2D images of the pore space were generated using backscattered electron microscopy and energy dispersive X-ray spectroscopy. A pre-precipitation scenario was created by digitally removing mineral matter identified as secondary precipitates. Porosity, determined by segmenting the images to distinguish pore space from mineral matter, was up to 0.11 less after reaction. Erosion-dilation analysis was used to compute pore and throat size distributions. Images with precipitation had more small and fewer large pores. Precipitation decreased throat sizes and the abundance of large throats. These findings agree with previous findings based on 3D X-ray CMT imaging, observing decreased porosity, clogging of small throats, and little change in large throats. However, 2D imaging found an increase in small pores, mainly in intragranular regions or below the resolution of the 3D images. Also, an increase in large pores observed via 3D imaging was not observed in the 2D analysis. Changes in flow conducting throats that are the key permeability-controlling features were observed in both methods. Abstract Copyright (2012) Elsevier, B.V.

Industrial roadmaps and analysts forecasts share visions of solar power becoming a major contributor to national and global electricity grids, with several terawatts of cumulative deployment by 2050 or earlier. For photovoltaics technology to become a major sustainable player in a competitive power-generation market, it must provide abundant, affordable electricity, with environmental impacts dramatically lower than those from conventional power generation. This article summarizes the prospects in each of three basic aspects of sustainability, namely, system costs, environmental impacts, and resource availability, all of which are examined in the context of prospective life-cycle assessment. Indeed, these three aspects are closely related: Increasing the efficiency of material recovery by recycling spent modules will become increasingly important in resolving cost, resource, and environmental constraints on large-scale sustainable growth.

In this paper, the in situ high-pressure angle dispersive X-ray diffraction experiment on TiSi2 (for C54 phase, space group:Fddd) has been performed using a diamond anvil cell with synchrotron radiation at room temperature. The diffraction patterns of C54 phase TiSi2 were gathered and its high-pressure structural stability was systematically analyzed. The lattice constants were refined using Rietveld method. With fixed B0 as 4, isothermal bulk modulus at ambient pressure was estimated as 169(2) GPa, according to a secondorder Birch-Murnaghan equation of state.

A second-order Birch-Murnaghan equation of state was used to fit the data. As the substitution of the PO (sub 4) (super 3-) cations by the VO (sub 4) (super 3-) cations progresses, the isothermal bulk modulus steadily decreases, with a maximum reduction of about 16% (from 68.4(16) GPa for Pb (sub 10) (PO (sub 4) ) (sub 6) F (sub 2) to 57.2(28) GPa for Pb (sub 10) (VO (sub 4) ) (sub 6) F (sub 2) ). For the entire composition range, the a-axis dimension remains more compressible than the c-axis dimension, with the ratio of the axial bulk moduli (K (sub T-c) :K (sub T-a) ) larger than 1. The ratio of K (sub T-c) to K (sub T-a) increases from about 1.04(4) to 1.23(14) as the composition parameter x increases from 0 to 6, suggesting that the apatite solid solutions Pb (sub 10) [(PO (sub 4) ) (sub 6-x) (VO (sub 4) ) (sub x) ]F (sub 2) become more elastically anisotropic.

Disks of enriched zinc were prepared by electrodeposition of [super]68Zn on aluminum or titanium substrate and isolated in the aluminum capsule for irradition. Irradiations were carried out with 128, 105 and 92 MeV protons for at least 24 h. After irradiation the disk was chemically processed to measure production yield and specific activity of [super]67Cu and to reclaim the target material. The recovered [super]68Zn was irradiated and processed again. The chemical procedure comprised BioRad cation exchange, Chelex-100 and anion exchange columns. Reduction of the oxidation degree of copper allowed for more efficient Cu/Co/Zn separation on the anion exchange column. No radionuclides other than copper isotopes were detected in the final product. The chemical yield of [super]67Cu reached 92-95% under remote handling conditions in a hot box. Production yield of [super]67Cu averaged 29.2 mu Ci/[ mu A-hg [super]68Zn] (1.08 MBq/[ mu A-hg [super]68Zn]) in 24 h irradiations. The best specific activity achieved was 18.6 mCi/ mu g (688.2 MBq/ mu g).

Similar deficits have been reported in cocaine-addicts and cocaine-exposed primates. We found that D2R/D3R binding availability negatively correlated with measures of body weight at the time of scan (ventral striatum), at 1 (ventral striatum) and 2 months (dorsal and ventral striatum) post scan in rats. Cocaine preference was negatively correlated with D2R/D3R binding availability 2 months (ventral striatum) post scan. Our findings suggest that inherent deficits in striatal D2R/D3R signaling are related to obesity and drug addiction susceptibility and that ventral and dorsal striatum serve dissociable roles in maintaining weight gain and cocaine preference. Measuring D2R/D3R binding availability provides a way for assessing susceptibility to weight gain and cocaine abuse in rodents and given the translational nature of PET imaging, potentially primates and humans.

Trace gas and aerosol measurements are presented as a function of longitude, altitude, and dew point in this study. Spatial distributions are consistent with an upper atmospheric source for O sub(3) and South American coastal sources for marine boundary layer (MBL) CO and aerosol, most of which is acidic sulfate. Pollutant layers in the free troposphere (FT) can be a result of emissions to the north in Peru or long range transport from the west. At a given altitude in the FT (up to 3 km), dew point varies by 40 degree C with dry air descending from the upper atmospheric and moist air having a boundary layer (BL) contribution. Ascent of BL air to a cold high altitude results in the condensation and precipitation removal of all but a few percent of BL water along with aerosol that served as CCN. Thus, aerosol volume decreases with dew point in the FT. Aerosol size spectra have a bimodal structure in the MBL and an intermediate diameter unimodal distribution in the FT. Comparing cloud droplet number concentration (CDNC) and pre-cloud aerosol (D sub(p)>100 nm) gives a linear relation up to a number concentration of ~150 cm super(-3), followed by a less than proportional increase in CDNC at higher aerosol number concentration. A number balance between below cloud aerosol and cloud droplets indicates that ~25 % of aerosol with D sub(p)>100 nm are interstitial (not activated). A direct comparison of pre-cloud and in-cloud aerosol yields a higher estimate. Artifacts in the measurement of interstitial aerosol due to droplet shatter and evaporation are discussed. Within each of 102 constant altitude cloud transects, CDNC and interstitial aerosol were anti-correlated. An examination of one cloud as a case study shows that the interstitial aerosol appears to have a background, upon which is superimposed a high frequency signal that contains the anti-correlation. The anti-correlation is a possible source of information on particle activation or evaporation.

However, the molecular effects of, e.g., adhesion/aggregation bonds of blood clotting can be on the order of nm. The coupling of the disparate length and timescales between such molecular levels and macroscopic transport represents a major computational challenge. To address this challenge, a multiscale numerical approach based on discrete particle dynamics (DPD) methodology derived from molecular dynamics (MD) principles is proposed. The feasibility of the approach was firstly tested for its ability to simulate viscous flow conditions. Simulations were conducted in low Reynolds numbers flows (Re = 25-33) through constricted tubes representing blood vessels with various degrees of stenosis. Multiple discrete particles interacting with each other were simulated, with 1.24-1.36 million particles representing the flow domain and 0.4 million particles representing the vessel wall. The computation was carried out on the massive parallel supercomputer NY BlueGene/L employing NAMD-a parallel MD package for high performance computing (HPC). Typical recirculation zones were formed distal to the stenoses. The velocity profiles and recirculation zones were in excellent agreement with computational fluid dynamics (CFD) 3D Navier-Stokes viscous fluid flow simulations and with classic numerical and experimental results by YC Fung in constricted tubes. This feasibility analysis demonstrates the potential of a methodology that widely departs from a continuum approach to simulate multiscale phenomena such as flow induced blood clotting.

The Pt mass activity of the Pt sub(ML)/IrNi/C electrocatalyst obtained in a scale-up synthesis is approximately 3 times higher than that of the commercial Pt/C electrocatalyst. The electronic and geometrical effects of the IrNi substrate on the Pt monolayer result in its higher catalytic activity than that of Pt nanoparticles. The structure and composition of the core-shell nanoparticles were verified using transmission electron microscopy and in situX-ray absorption spectroscopy, while a potential cycling test was employed to confirm the stability of the electrocatalyst. Our experimental results, supported by the density functional calculations using a sphere-like model, demonstrate an effective way of using Pt that can resolve key problems of cathodic oxygen reduction hampering fuel cell commercialization.

CSIRO has sought to address the lack of information by focusing on the generation of detailed chemical and mineralogical data from a range of Australian uranium deposit types (e.g. IOCGU, surficial, metasomatite, unconformity-related, and sandstone-hosted). For representative samples from each deposit, the abundance and type of uranium minerals and associated gangue were determined using a combination of techniques including XRD, high-resolution electron probe microanalysis (EPMA), QEMScan and synchrotron-based X-ray microscopy (mu -XRF and -mu XRD). This study presents data from one type of uranium deposit, the low-grade surficial or calcrete-hosted uranium (CHU) group. Results showed three uranium phases were present: the more abundant phase was carnotite (K (sub 2) [UO (sub 2) ] (sub 2) [VO (sub 4) ]2.3H (sub 2) O) while the two minor phases were uraninite (UO (sub 2) ) and uranothorite ([U,Th]SiO (sub 4) ). Carnotite was present as micro-grain (<2-7 mu m) inclusions within silicate and calcareous gangue. In rare occurrences, carnotite also formed a cement phase binding unmineralised gangue grains. Uraninite and uranothorite were associated with the carnotite cement. The multiple techniques contributed key pieces of information to accurately characterise the ore and provided insight into the mineralogical factors of importance when considering uranium extraction e.g. carnotite inclusions within gangue will likely require liberation prior to leaching, plus the incomplete alteration of a pre-existing uranium mineralisation phase may result in relict U (super 4+) species requiring a separate extraction/leach process.

L-ribulokinase, encoded by the araB gene, catalyzes conversion of L-ribulose to L-ribulose-5-phosphate, the second step in the catabolic pathway. Unlike other kinases, ribulokinase exhibits diversity in substrate selectivity and catalyzes phosphorylation of all four 2-ketopentose sugars with comparable k sub(cat) values. To understand ribulokinase recognition and phosphorylation of a diverse set of substrates, we have determined the X-ray structure of ribulokinase from Bacillus halodurans bound to L-ribulose and investigated its substrate and ATP co-factor binding properties. The polypeptide chain is folded into two domains, one small and the other large, with a deep cleft in between. By analogy with related sugar kinases, we identified super(447) GG LPQ K super(452) as the ATP-binding motif within the smaller domain. L-ribulose binds in the cleft between the two domains via hydrogen bonds with the side chains of highly conserved Trp126, Lys208, Asp274, and Glu329 and the main chain nitrogen of Ala96. The interaction of L-ribulokinase with L-ribulose reveals versatile structural features that help explain recognition of various 2-ketopentose substrates and competitive inhibition by L-erythrulose. Comparison of our structure to that of the structures of other sugar kinases revealed conformational variations that suggest domain-domain closure movements are responsible for establishing the observed active site environment.

Our goal is to understand the accumulation and storage of nitrogen in soils. The overarching hypothesis that drives this research is that heterocyclic N compounds derived from the decomposition of litter are transported and accumulate in the soil column. The analytical approaches typically used to study N-containing compounds are not sensitive to the presence of heterocyclic N. This has resulted in the general belief that amide-N (as in proteins/peptides) is the only N form important in N accumulation and storage in soils. Still, biomolecules such as DNA are composed of heterocyclic N containing subunits and these molecules, although in lower concentrations than amide-N in proteins/peptides, are chemically recalcitrant, sorb onto soil solids, and are thus expected to accumulate and persist in natural soil environments. In this investigation, we used an innovative technique, nitrogen X-ray absorption near edge structure (N-XANES) spectroscopy, to determine the N chemical forms in temperate forest soils as a function of depth and varying mineralogy. Soil columns (down to approx. 1 meter) were collected from two forest locations in Pennsylvania. These include an Inceptisol soil with mineralogy dominated by illite and chlorite, and a Spodosol soil with mineralogy dominated by Fe oxides, illite and kaolinite, but that also contains organic matter accumulations at depths of about 25-50 cm. The N K-edge (409.9 eV) XANES spectra was collected at the National Synchrotron Light Source, BNL. The N-XANES spectra of these forest soils can be divided into two regions: pi * resonances at 398-404 eV and sigma * resonances at 404-420 eV. Furthermore, the spectra reveal two well-resolved pi * resonances, one (lower energy pi *) corresponding to spectral features present in biomolecules such as DNA/RNA and their constituent nucleic acids, and a second resonance (higher energy pi *) which is present in proteins and their constituent amino acids and polypeptides. We observed an increase in the lower energy pi * resonance with soil depth that was mirrored by a decrease in the higher energy pi * resonance. This trend is consistent for all soil columns, except when an accumulation of organic matter occurs in deep soil layers. The lower energy pi * resonance originates from molecular structures with extended pi -electron systems and indicate the presence of heterocyclic N compounds. Thus, our results indicate N long-term leaching processes result in the selective accumulation of heterocyclic N compounds at soil depths. The accumulation of heterocyclic N at soil depths might be a consequence of its presumed recalcitrance and/or bonding to mineral surfaces.

METHOD: The biodistribution and toxicological profile of this porphyrin has been shown to be favourable for another bimodal radiotherapy technique, boron neutron-capture therapy. For the XRT studies, CuTCPBr was formulated in either 9% Cremophor registered (BASF Corporation, Ludwigschafen, Germany) EL and 18% propylene glycol (9% CRM) or a revised formulation comprising 1% Cremophor ELP, 2% Tween 80 registered (JT Baker, Mansfield, MA), 5% ethanol and 2.2% PEG 400 (CTEP formulation), which would be more clinically acceptable than the original 9% CRM formulation. Using the 9% CRM formulation of CuTCPBr, doses of 100, 210 or 400 mg kg-1 of body weight were used in combination with single doses of 25-35 Gy 100 kVp X-rays. RESULTS: While doses of 100 mg kg-1 and 210 mg kg-1 did not result in any significant enhancement of tumour response, the 400 mg kg-1 dose did. A dose modification factor of 1.20 plus or minus 0.10 was obtained based on the comparison of doses that produced a 50% local tumour control probability. With the CTEP formulation of CuTCPBr, doses of 83 and 170 mg kg-1 produced significant radiation enhancement, with dose modification factors based on the TCP50 of 1.29 plus or minus 0.15 and 1.84 plus or minus 0.24, respectively. CONCLUSION: CuTCPBr significantly enhanced the efficacy of XRT in the treatment of EMT-6 carcinomas in mice. The CTEP formulation showed a marked improvement, with over 9% CRM being associated with higher dose modification factors. Moreover, the radiation response in the skin was not enhanced.

A lack of knowledge about its biogeochemistry coupled with its unique and advantageous properties have led to an explosion of W based products for domestic, military, and industrial applications. Recently W has come under scrutiny following a CDC investigation of a leukemia cluster in Fallon, Nevada which implicated high levels of W in the drinking water as a probable cause. Besides W's potential health hazards, recent studies have shown that the WO (sub 4) (super 2-) oxyanion is soluble in water, capable of moving through soils. Also, dissolution of W metal leads to decreases in bacterial biomass in soils and increases in fungal biomass, also having adverse effects on plant life. The hypothesis to be tested is that the physical and chemical changes from chemical weathering, mineral dissolution and precipitation, and/or redox reactions catalyzed by microbial activity control W transport and sequestration. These parameters control W by means of adsorptive/desorptive reactions, reductive/oxidative mineral dissolution or aqueous complexation with sulfide. Three sites have been chosen for geochemical and mineralogical analysis; two sites of high W concentrations (Fallon and Hoisington, KS) and one site of low concentration (Carrizo aquifer, Texas). Surface samples from within the town of Fallon and in-lake sediments from Cheyenne Bottoms Refuge in Hoisington have both shown high levels of W. The first step used in understanding the W-sediment association is x-ray microprobe aided speciation and bulk XANES, utilizing synchrotron radiation. This is done with mu XRF mapping accompanied by mu XANES and mu XRD on mineral/sediment grains and also elucidates the association of W with other elements (Ca, Fe, Mn, Fe, As, Cu, Mo, Ti, Zn). Sediment samples from Fallon were analyzed for bulk W speciation, and the data showed predominately W-VI, though the presence of minor shoulders in the spectra may indicate the presence of other species. The mu XRF map revealed that the highest density of W hotspots was in samples nearest the hard-metal facility, and good correlations were found with Fe. Sequential extractions are also being done to understand the partitioning of sediment fractions and preference of W to bind with various fractions.

They cause paralysis at less than picomolar concentration by blocking neurotransmitter release. BoNT consists of a heavy chain and a light chain. The C-terminal half of the heavy chain allows the toxin to bind to the presynaptic membrane while the N-terminal half helps in forming a channel in the endosomal membrane to allow the light chain to escape into the cytosol. While the binding and catalytic mechanisms are well understood now, the details of translocation still remain a mystery. A full length BoNT-A heavy chain (BAHC) has been cloned, over expressed and purified from inclusion bodies by solubilising with a detergent. Preliminary crystallographic results show that BAHC forms a tetramer in the crystal lending experimental support for tetrameric pore formation for the light chain to pass through the endosomal membrane.

AN - 912428344; 22141466 AB - Many researchers have focused in recent years on resolving the crucial problem of capacity fading in Li ion batteries when carbon anodes are replaced by other group-IV elements (Si, Ge, Sn) with much higher capacities. Some progress was achieved by using different nanostructures (mainly carbon coatings), with which the cycle numbers reached 100-200. However, obtaining longer stability via a simple process remains challenging. Here we demonstrate that a nanostructure of amorphous hierarchical porous GeO(x) whose primary particles are ~3.7 nm diameter has a very stable capacity of ~1250 mA h g(-1) for 600 cycles. Furthermore, we show that a full cell coupled with a Li(NiCoMn)(1/3)O(2) cathode exhibits high performance.

Leakage of CO (sub 2) -acidified brine may lead to geochemical alterations of the fracture geometry that may alter fracture permeability. Accurate prediction of CO (sub 2) leakage potential requires bridging the gap between small-scale models and laboratory experiments, which have limited scope in space and time, and basin-scale leakage models. Results from two CO (sub 2) -acidified brine flow-through experiments performed on artificially-fractured carbonate caprock samples will be presented. Although the two experiments used core samples taken from the same formation only centimeters apart, they resulted in two very different outcomes with respect to fracture permeability evolution. One experiment exhibited extensive deterioration along the fracture due primarily to dissolution of calcite, while the other exhibited a net decrease in fracture permeability due to a combination of mineral precipitation and particle clogging. The stark difference observed in the two experiments, for rocks from the same formation, suggests caprock fracture evolution is highly sensitive to variations in mineral spatial heterogeneity, brine composition and flow conditions. In addition to the laboratory experiments, we have developed a reactive-transport pore-network model that is capable of simulating alterations in network permeability and porosity due to flow of a CO (sub 2) -acidified brine phase through carbonate rocks. The pore-network model will help us identify the important flow and geochemical conditions in which precipitation and dissolution occur. These small-scale projects will be used to inform a basin-scale leakage model of the pertinent range of geochemical conditions that should be tested in order to determine 1-D permeability evolution of leakage pathways. Finally, simplified mathematical rules will be derived to describe the geochemical alterations of flow paths and potential for permeability to change over time.

AN - 905670023; 21592305 AB - The seven serotypes of Clostridium botulinum neurotoxins (A-G) are the deadliest poison known to humans. They share significant sequence homology and hence possess similar structure-function relationships. Botulinum neurotoxins (BoNT) act via a four-step mechanism, viz., binding and internalization to neuronal cells, translocation of the catalytic domain into the cytosol and finally cleavage of one of the three soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNARE) causing blockage of neurotransmitter release leading to flaccid paralysis. Crystal structures of three holotoxins, BoNT/A, B and E, are available to date. Although the individual domains are remarkably similar, their domain organization is different. These structures have helped in correlating the structural and functional domains. This has led to the determination of structures of individual domains and combinations of them. Crystal structures of catalytic domains of all serotypes and several binding domains are now available. The catalytic domains are zinc endopeptidases and share significant sequence and structural homology. The active site architecture and the catalytic mechanism are similar although the binding mode of individual substrates may be different, dictating substrate specificity and peptide cleavage selectivity. Crystal structures of catalytic domains with substrate peptides provide clues to specificity and selectivity unique to BoNTs. Crystal structures of the receptor domain in complex with ganglioside or the protein receptor have provided information about the binding of botulinum neurotoxin to the neuronal cell. An overview of the structure-function relationship correlating the 3D structures with biochemical and biophysical data and how they can be used for structure-based drug discovery is presented here.

Activity was determined by analyzing the hydrolysis of para-nitrobenzene carbohydrate derivatives. In general, the enzymes were most active in the dimethyl phosphate ionic liquids, followed by acetate. Generally speaking, activity decreased sharply for concentrations of [emim][dep] above 10% v/v, while the other ionic liquids showed less impact on activity up to 20% v/v.

Secondary minerals of sodalite and cancrinite have been shown to nucleate on, and cement together, quartz grains. These secondary precipitates have been found to uptake radionuclides in their network of channels and cages. In this work, thin sections from unreacted and reacted column experiments packed with Hanford sand grains were imaged using 2D Scanning Electron Microscopy (SEM). SEM image analysis reveals large amounts of intragranular pore space in both the reacted and unreacted sands. Grayscale Backscattered Electron (BSE) images were thresholded to separate grain and pore pixels. To quantify the amount of intragranular pore space, a set of images were manually created with the intragranular pore space removed, or the grains filled-in. Porosity, and intragranular porosity, was determined by counting and comparing the number of pore pixels in each pair of images. Intragranular pore space accounts for up to 14% of total porosity. Quartz dissolution in intragranular regions increases the proportion of intragranular pore space in reacted samples. Diffusion of tank waste into these free silica rich areas provides a favorable environment for cancrinite precipitates to form and a potential significant trapping mechanism for radionuclides. Part of this work was to quantify where, within a single pore and a network of pores, precipitation occurred. While the bulk amount of cancrinite precipitation occurred on grain surfaces, cancrinite precipitates were also found in intragranular pore spaces. Up to 10% of total precipitation occurred in intragranular pore space. However, as the system recovers and clean water flow returns, radionuclides incorporated into precipitates in intragranular regions may act as a secondary long term leaching source for contaminants. To determine the trapping or leaching potential from intragranular regions, the diffusion time from intraparticle pores is determined using a radial grain diffusion model. Surface precipitates may increase diffusion times and further limit radionuclide transport to the formation water.

While effects on porosity are relatively well understood, changes in permeability are more difficult to estimate. In this work, pore-network modeling is used to estimate the permeability of a porous medium using pore and throat size distributions. These distributions can be determined from 2D Scanning Electron Microscopy (SEM) images of thin sections or from 3D X-ray Computed Tomography (CT) images of small cores. Each method has unique advantages as well as unique sources of error. 3D CT imaging has the advantage of reconstructing a 3D pore network without the inherent geometry-based biases of 2D images but is limited by resolutions around 1 mu m. 2D SEM imaging has the advantage of higher resolution, and the ability to examine sub-grain scale variations in porosity and mineralogy, but is limited by the small size of the sample of pores that are quantified. A pore network model was created to estimate flow permeability in a sand-packed experimental column investigating reaction of sediments with caustic radioactive tank wastes in the context of the Hanford, WA site. Before, periodically during, and after reaction, 3D images of the porous medium in the column were produced using the X2B beam line facility at the National Synchrotron Light Source (NSLS) at Brookhaven National Lab. These images were interpreted using 3DMA-Rock to characterize the pore and throat size distributions. After completion of the experiment, the column was sectioned and imaged using 2D SEM in backscattered electron mode. The 2D images were interpreted using erosion-dilation to estimate the pore and throat size distributions. A bias correction was determined by comparison with the 3D image data. A special image processing method was developed to infer the pore space before reaction by digitally removing the precipitate. The different sets of pore property distributions were used to generate different network flow models, to examine permeability alterations due to reaction-induced changes in throat sizes. 3D CT images, limited to a resolution of approximately 4 microns, miss small throats present at grain-to-grain contacts. The higher resolution of SEM images captures small throats between grains, however grain surface roughness and other small scale features may be misinterpreted. Precise determination of throat distributions requires careful thresholding to distinguish flow-conducting throats from throats leading to pores that are really just surface roughness. Using the pore network model, the sensitivity of permeability to the throat size roughness threshold was evaluated. Permeabilities calculated from the 2D and 3D pore and throat size distributions are compared to determine the impact of the lower resolution 3D images missing small throats.

Fractures in these caprocks, whether preexisting or newly created due to CO (sub 2) injection, may serve as leakage pathways for the injected CO (sub 2) . The hydrodynamic properties of these fractures, e.g. permeability and relative permeability, are primarily controlled by fracture geometries, aperture and roughness, which are subject to alteration caused by reactions between CO (sub 2) -acidified brine and minerals along the fracture faces. In this study, computational fluid dynamics simulations were performed on fracture geometries representing the initial and final conditions of an experiment in which a fractured carbonate caprock sample was exposed to CO (sub 2) -acidified brine flow. This experiment exhibited a net decrease in average fracture aperture. X-ray computed micro-tomography scans taken before and after the experiment were thresholded and used to reconstruct the fracture geometries. The generated meshes were refined and used in OpenFOAM for single-phase flow simulations to estimate intrinsic permeabilities. The simulation results carry important implications regarding the impact of geochemical reactions along the fracture pathway on hydrodynamic properties. Results from this study will provide important insights for leakage risk assessment of CO (sub 2) storage sites with potentially fractured caprocks.

To better understand these geochemical processes we have developed a reactive transport pore network model to investigate the mechanisms by which upscaled parameters for porosity and permeability change due to spatially heterogeneous dissolution or precipitation of carbonate minerals. The parameter space explored consists of the concentration of CO (sub 2) in brine, the pH as controlled by the amount of Ca (super 2+) and Mg (super 2+) in solution, the flow conditions (i.e. diffusion- or advection-controlled regimes) and the heterogeneous distribution of reactive minerals. Our results indicate that the evolution of permeability and porosity fields differ significantly with boundary pH and flow regime. With boundary pH values above 5 precipitation of calcite is the dominant mechanism by which porosity and permeability change. The flow regimes dictate the evolution of porosity vs. permeability curves, which can be bundled into a family of curves. The heterogeneous distribution of minerals creates conditions under which dissolution dominated systems might create precipitation followed by dissolution or vice versa and the evolution of the upscaled parameters depend on the type of mineral heterogeneity.

Compared to other environments the absorption spectrum shows higher intensity at the shortest wavelengths, and a weak apparent absorption peak is observed at 280 nm. The resolved fluorescence excitation spectrum has five peaks at positions corresponding to those observed in the absorption spectrum. The position of the fluorescence maximum depends on the excitation wavelength. Excitation below 220 nm displays a fluorescence maximum at 305 nm, while for excitations at higher wavelengths the maximum occurs at 335 nm. The results suggest that multiple-emission excited electronic states are populated in low-temperature gas matrices. Excitation at 265 nm produces a phosphorescence spectrum with a well-resolved vibrational structure and a maximum at 415 nm. The fluorescence decays corresponding to excitation at increasing energy of each resolved band could be fit with a double exponential, with the shorter and longer lifetimes ranging from 1.7 to 3.3 ns and from 12 to 23 ns, respectively. Only for the excitation at 180 nm one exponential is required, with the calculated lifetimes of 3.3 ns. The presented results provide an experimental evidence of the existence of multiple site-selected excited electronic states, and may help elucidate the possible deexcitation pathways of adenine. The additional application of synchrotron radiation proved to result in a significant enhancement of the resolution and spectral range of the phenomena under investigation.

It utilizes the energy of the Fe Kalpha absorption edge and its pre-edge, which are known to be very sensitive to the oxidation state of Fe. Previous work has concentrated on the pre-edge region, and studies of isotropic glasses and garnets with restricted compositional ranges have yielded excellent results. However, broader application of micro-XANES has been hampered by differential interactions of the plane-polarized X-ray beam with anisotropic crystals that result in + or - 15-20% errors for Fe (super 3+) /Sigma Fe measurements based on pre-edge spectra of randomly-oriented crystals. Moreover, different mineral groups require separate calibration lines because the geometries of their Fe polyhedra are so variable. Finally, use of solely the pre-edge region for modeling Fe (super 3+) contents ignores valuable information contained in the main absorption edge. We demonstrate here that these problems can be overcome by use of oriented standards and multivariate analysis. For anisotropic mineral groups, we have acquired spectra with the crystals oriented with the polarization direction of the synchrotron beam is parallel to the X, Y, and Z optical orientation directions in the crystals, providing end-members of spectra for samples with extremes of Fe (super 3+) /Sigma Fe and orientation. We extracted the pre-edge region of the XANES spectra to fit component peaks representing contributions from both Fe (super 2+) and Fe (super 3+) in this region, and created a calibration curve that regresses the area-normalized centroid of those pre-edges to known Fe (super 3+) /Sigma Fe from bulk methods. These results were compared with those from multivariate analysis models such as partial least-squares analysis (PLS), which predict Fe (super 3+) /Sigma Fe using spectra from the entire XANES region. Results shows that multivariate analysis yields equivalent or more accurate predictions of Fe (super 3+) in garnets, amphiboles, micas, and glasses to techniques based on the pre-edge region only, with improved robustness and generalizability.

Substantial fractions of about half of the proteins formed insoluble aggregates, consistent with the hypothesis that these proteins were produced at rates or in amounts that exceeded the protein-folding capacity of GroEL. In addition, large fractions of three overexpressed GroEL client proteins were localized in an extra-cytoplasmic, osmotically-sensitive compartment, suggesting they had initially accumulated in the cytoplasm as soluble unfolded polypeptides and thus were able to access a protein export pathway. Consistent with this model, an intrinsically unfoldable, hydrophilic, non-secretory polypeptide was quantitatively exported from the E. coli cytoplasm into an osmotically-sensitive compartment. Our results support the conclusion that a soluble, unfolded conformation alone may be sufficient to direct non-secretory polypeptides into a protein export pathway for signal peptide-independent translocation across the inner membrane, and that export rather than degradation by cytoplasmic proteases is the preferred fate for newly-synthesized, soluble, unfolded polypeptides that accumulate in the cytoplasm. The stable folded conformation of exported GroEL client proteins further suggests that the requirement for GroEL may be conditional on protein folding in the molecularly-crowded environment of the cytoplasm.

AN - 885280039; 21780827 AB - Core-shell nanoparticles increasingly are found to be effective in enhancing catalytic performance through the favorable influence of the core materials on the active components at the surface. Yet, sustaining high activities under operating conditions often has proven challenging. Here we explain how differences in the components' diffusivity affect the formation and stability of the core-shell and hollow nanostructures, which we ascribe to the Kirkendall effect. Using Ni nanoparticles as the templates, we fabricated compact and smooth Pt hollow nanocrystals that exhibit a sustained enhancement in Pt mass activity for oxygen reduction in acid fuel cells. This is achieved by the hollow-induced lattice contraction, high surface area per mass, and oxidation-resistant surface morphology--a new route for enhancing both the catalysts' activity and durability. The results indicate challenges and opportunities brought by the nanoscale Kirkendall effect for designing, at the atomic level, nanostructures with a wide range of novel properties.

The structural models of the as-prepared hydrated phases and their dehydrated forms at elevated temperature were refined in space group Fdd2 using in situ synchrotron X-ray powder diffraction data and Rietveld methods. The unit-cell volumes of the hydrated NH (sub 4) -exchanged natrolites at ambient conditions, (NH (sub 4) ) (sub 16(2)) Al (sub 16) Si (sub 24) O (sub 80) .14.1(9)H (sub 2) O and (NH (sub 4) ) (sub 5.1(1)) K (sub 10.9(1)) Al (sub 16) Si (sub 24) O (sub 80) .15.7(3)H (sub 2) O, are found to be larger than that the original sodium-natrolite by ca. 15.6% and 12.8%, respectively. Upon temperature increase, the fully NH (sub 4) -exchanged natrolite undergoes dehydration at ca. 150 degrees C with ca. 16.4% contraction in the unit-cell volume. The dehydrated phase of the fully NH (sub 4) -exchanged natrolite exhibits marginal volume expansion up to 425 degrees C and then becomes amorphized during temperature decrease and exposure to atmospheric condition. In the case of the partially NH (sub 4) -exchanged natrolite, the dehydration starts from ca. 175 degrees C with approximately 15.1% volume contraction and leads to a partial phase separation to show a phase related to the dehydrated K-natrolite. The degree of the phase separation decreases with temperature increase up to 475 degrees C, concomitant to the gradual volume contraction occurring in the partially NH (sub 4) -exchanged natrolite in the dehydrared state. Upon temperature decrease and exposure to atmospheric condition, only the dehydrated K-natrolite is recovered as a crystalline phase from the partially NH (sub 4) -exchanged natrolite. In the hydrated model of the fully NH (sub 4) -exchanged natrolite, the ammonium cations and water molecules are statistically distributed along the elliptical channels, similar to the disordered pattern observed in natrolites exchanged with larger alkali metal cations such as the K-, Rb-, and Cs-forms. The dehydrated model of the fully NH (sub 4) -exchanged natrolite at 400 degrees C is essentially same as the one reported previously from the sample prepared by direct melt exchange method using sodium-natrolite. Both the hydrated and dehydrated structures of the partially NH (sub 4) -exchanged natrolite at RT and at 400 degrees C, respectively, are characterized by having two separate sites for the ammonium and potassium cations. Comparing the structural models of the monovalent cation forms studied so far, we find that the rotation angle of the natrolite chain is inversely proportional to the cation radius both in the hydrated and dehydrated phases. The distribution pattern of the non-framework species along the natrolite channel also seems to be related to the non-framework cation radius and hence to the chain rotation angle.

However the variability in the distribution of these brain hubs is unknown due in part to the overwhelming computational demands associated to their localization. Recently we developed a fast algorithm to map the local functional connectivity density (lFCD). Here we extend our method to map the global density (gFDC) taking advantage of parallel computing. We mapped the gFCD in the brain of 1031 subjects from the 1000 Functional Connectomes project and show that the strongest hubs are located in regions of the default mode network (DMN) and in sensory cortices, whereas subcortical regions exhibited the weakest hubs. The strongest hubs were consistently located in ventral precuneus/cingulate gyrus (previously identified by other analytical methods including lFCD) and in primary visual cortex (BA 17/18), which highlights their centrality to resting connectivity networks. In contrast and after rescaling, hubs in prefrontal regions had lower gFCD than lFCD, which suggests that their local functional connectivity (as opposed to long-range connectivity) prevails in the resting state. The power scaling of the probability distribution of gFCD hubs (as for lFCD) was consistent across research centers further corroborating the "scale-free" topology of brain networks. Within and between-subject variability for gFCD were twice than that for lFCD (20% vs. 12% and 84% vs. 34%, respectively) suggesting that gFCD is more sensitive to individual differences in functional connectivity.

Such life-cycle analyses of energy technologies are essential, especially as material and energy flows are often interwoven, and divergent emissions into the environment may occur at different life-cycle-stages. This approach is well exemplified by our description of material and energy flows in four commercial PV technologies, i.e., mono-crystalline silicon, multi-crystalline silicon, ribbon-silicon, and cadmium telluride. The same life-cycle approach is applied to the balance of system that supports flat, fixed PV modules during operation. We also discuss the life-cycle environmental metrics for a concentration PV system with a tracker and lenses to capture more sunlight per cell area than the flat, fixed system but requires large auxiliary components. Select life-cycle risk indicators for PV, i.e., fatalities, injures, and maximum consequences are evaluated in a comparative context with other electricity-generation pathways.

The environmental issues related to the installation and operation phases of such facilities have not, so far, been addressed comprehensively in the literature. Here we identify and appraise 32 impacts from these phases, under the themes of land use intensity, human health and well-being, plant and animal life, geohydrological resources, and climate change. Our appraisals assume that electricity generated by new solar power facilities will displace electricity from traditional U.S. generation technologies. Altogether we find 22 of the considered 32 impacts to be beneficial. Of the remaining 10 impacts, 4 are neutral, and 6 require further research before they can be appraised. None of the impacts are negative relative to traditional power generation. We rank the impacts in terms of priority, and find all the high-priority impacts to be beneficial. In quantitative terms, large-scale solar power plants occupy the same or less land per kW h than coal power plant life cycles. Removal of forests to make space for solar power causes CO sub(2 emissions as high as 36 g CO) sub(2) kW h[super]-1, which is a significant contribution to the life cycle CO sub(2 emissions of solar power, but is still low compared to CO) sub(2) emissions from coal-based electricity that are about 1100 g CO sub(2 kW h[super]-1.)

An analytical expression is first derived to quantify the relationship between cloud radiative forcing, cloud fraction, and cloud albedo. The analytical expression is then used to deduce a new approach for inferring cloud albedo from concurrent surface-based measurements of downwelling surface shortwave radiation and cloud fraction. High-resolution decade-long data on cloud albedos are obtained by use of this surface-based approach over the US Department of Energy's Atmospheric Radiaton Measurement (ARM) Program at the Great Southern Plains (SGP) site. The surface-based cloud albedos are further compared against those derived from the coincident GOES satellite measurements. The three long-term (1997-2009) sets of hourly data on shortwave cloud radiative forcing, cloud fraction and cloud albedo collected over the SGP site are analyzed to explore the multiscale (diurnal, annual and inter-annual) variations and covariations. The analytical formulation is useful for diagnosing deficiencies of cloud-radiation parameterizations in climate models.

However, DMA application at the pilot or industrial production scale remains infeasible because of the low mass throughput. A simple way to scale up DMA operation is to use multiple DMA columns. The manufacture and maintenance costs of existing DMAs, however, limit such a scale-up. A cost-effective DMA column (named cDMA) has thus been developed in this work to address the above issue. To reduce its manufacturing cost, the prototype was constructed using parts requiring little machining. The cDMA column was also designed for easy maintenance and easy variation of the classification length for any application-specified size range. In this study, prototypes with two particle classification lengths, 1.75 and 4.50 cm, were constructed and their performance was experimentally evaluated at sheath-to-aerosol flowrate ratios of 5:1, 10:1, and 15:1 via the tandem DMA (TDMA) technique. It was concluded that both prototype cDMAs, operated at a sheath/aerosol flowrate ratio less than 15:1 and with a polydisperse aerosol flowrate of 1.0 lpm, achieved sizing resolution comparable to that offered by Nano-DMA. The longer cDMA had comparable transmission efficiency to that of Nano-DMA, and the shorter cDMA exceeded the performance of Nano-DMA. Hence, the cDMA with the shorter (1.75 cm) classification length is better suited for the characterization of macromolecular samples. DMA application at the pilot or industrial production scale remains infeasible because of the low mass throughput of DMAs. The manufacture and maintenance costs of existing DMAs are limiting factors for the scale-up operation using multiple columns. In this work we have developed a cost-effective DMA column (named cDMA) to address the cost issues. Tandem DMA experiment has shown that the developed cDMAs have the performance in general comparable or better than that of Nano-DMA.

Here we compare biologic rhythms gleaned from mammoth's hairs with those of modern human hair. Four mammoths' hairs came from varying locations in Siberia 4600 km, four time zones, apart ranging in age between 18,000 and 20,000 years before present. We used two contemporaneous human hairs for comparison. Power spectra derived from hydrogen isotope ratios along the length of the hairs gave insight into biologic rhythms, which were different in the mammoths depending on location and differed from humans. Hair growth for mammoths was approximately 31 cms/year and approximately 16 cms/year for humans. Recurrent annual rhythms of slow and fast growth varying from 3.4 weeks/cycles to 8.7 weeks/cycles for slow periods and 1.2 weeks/cycles to 2.2 weeks/cycles for fast periods were identified in mammoth's hairs. The mineral content of mammoth's hairs was measured by electron microprobe analysis (k-ratios), which showed no differences in sulfur amongst the mammoth hairs but significantly more iron then in human hair. The fractal nature of the data derived from the hairs became evident in Mandelbrot sets derived from hydrogen isotope ratios, mineral content and geographic location. Confocal microscopy and scanning electron microscopy showed varied degrees of preservation of the cuticle largely independent of age but not location of the specimens. X-ray fluorescence microprobe and fluorescence computed micro-tomography analyses allowed evaluation of metal distribution and visualization of hollow tubes in the mammoth's hairs. Seasonal variations in iron and copper content combined with spectral analyses gave insights into variation in food intake of the animals. Biologic rhythms gleaned from power spectral plots obtained by modern methods revealed life style and behavior of extinct mega-fauna.

AN - 864780917; 21474305 AB - In this study, the effect of ionic liquids, 1-ethyl-3-methylimidazolium acetate [EMIM][Ac], 1-ethyl-3-methylimidazolium diethylphosphate [EMIM][DEP], and 1-methyl-3-methylimidazolium dimethylphosphate [MMIM][DMP] on the growth and glucose fermentation of Clostridium sp. was investigated. Among the three ionic liquids tested, [MMIM][DMP] was found to be least toxic. Growth of Clostridium sp. was not inhibited up to 2.5, 4 and 4 g L(-1) of [EMIM][Ac], [EMIM][DEP] and [MMIM][DMP], respectively. [EMIM][Ac] at <2.5 g L(-1), showed hormetic effect and stimulated the growth and fermentation by modulating medium pH. Total organic acid production increased in the presence of 2.5 and 2 g L(-1) of [EMIM][Ac] and [MMIM][DMP]. Ionic liquids had no significant influence on alcohol production at <2.5 g L(-1). Total gas production was affected by ILs at ≥ 2.5 g L(-1) and varied with type of methylimidazolium IL. Overall, the results show that the growth and fermentative metabolism of Clostridium sp. is not impacted by ILs at concentrations below 2.5 g L(-1).

Soil containing 2600 mg kg (super -1) Cu was amended with a combination of 5 wt% compost and 2 wt% iron grit, and vegetated. Sequential extraction was combined with extended X-ray absorption fine structure (EXAFS) spectroscopy to correlate changes in Cu distribution across five fractions with changes in the predominant Cu compounds two years after treatment in parallel treated and untreated field plots. Exchangeable Cu dominated untreated soil, most likely as Cu(II) species non-specifically bound to natural organic matter. The EXAFS spectroscopic results are consistent with the sequential extraction results, which show a major shift in Cu distribution as a result of soil treatment to the fraction bound to poorly crystalline Fe oxyhydroxides forming binuclear inner-sphere complexes.

The core samples are from the Amherstburg limestone, which is the caprock for a CO (sub 2) storage demonstration project in northern Michigan, USA. The evolution of fracture aperture was monitored in real time using X-ray computed tomography (CT). Before and after the experiment, 3-D reconstructions of the fracture structure, aperture and surface roughness were examined at higher resolution via micro X-ray CT. The cores were then sectioned and examined with scanning electron microscopy, X-ray fluorescence and micro X-ray diffraction. Although all three samples were of nearly identical mineralogical composition, the brine flow rates, initial brine compositions, and initial fracture permeabilities differed across the three samples. These differences in flow conditions and fluid composition generated different degrees of fracture deterioration. The first run resulted in substantial erosion of the fracture surface, while the second run had a decrease in fracture permeability that may be attributed to mineral precipitation along the fracture. Spectroscopic analysis of the samples after CO (sub 2) -brine flow demonstrated preferential calcite dissolution. Mineral spatial heterogeneity coupled with the preferential dissolution of calcite led to non-uniform degradation along the fracture and an increase in surface roughness. In areas where calcite is intermixed with dolomite and other silicate minerals the dissolution of calcite leads to the formation of a degraded zone along the fracture boundary, resulting in a smaller increase in fracture aperture. The potential mineral precipitation found in the second run is in stark contrast to the rapid mineral dissolution found in the first and suggests a complex interplay of mineral spatial heterogeneity, brine composition, and flow conditions controlling caprock fracture evolution. Results from this study will be we used to frame a discussion on how flow through caprock fractures may be influenced by geochemical alteration of fracture geometry.

This work uses experimental, computational, and analytical methods to investigate thermal mechanisms that drive electric power production in the TPV systems. An objective of this work is to produce results that will lead to the development of systems that generate enough electricity such that the boiler is self-powering. An important design constraint employed in this investigation is the use of conventional, yellow-flame oil burners, integrated with a typical boiler. The power production target for the systems developed here is 100 W - the power requirement for a boiler that uses low-power auxiliary components. The important heat transfer coupling mechanisms that drive power production in the systems studied are discussed. The results of this work may lead to the development of systems that export power to the home electric system.

The way this modification occurs is studied at the oil-water interface for a range of alkanes and two ionic surfactants. A liquid interfacial monolayer, consisting of a mixture of alkane molecules and surfactant tails, is found. Upon cooling, it freezes at T (sub s) , well above the alkane's bulk freezing temperature, T (sub b) . The monolayer's phase diagram, derived by surface tensiometry, is accounted for by a mixtures-based theory. The monolayer's structure is measured by high-energy X-ray reflectivity above and below T (sub s) . A solid-solid transition in the frozen monolayer, occurring approximately 3 degrees C below T (sub s) , is discovered and tentatively suggested to be a rotator-to-crystal transition.

However, the time course for iron accumulation is currently unclear. Using the PSAPP mouse model of amyloid plaque formation, we conducted a time course study of metal ion content and distribution [iron (Fe), copper (Cu), and zinc (Zn)] in the cortex and hippocampus using X-ray fluorescence microscopy (XFM). We found that iron in the cortex was 34% higher than age-matched controls at an early stage, corresponding to the commencement of plaque formation. The elevated iron was not associated with the amyloid plaques. Interestingly, none of the metal ions were elevated in the amyloid plaques until the latest time point (56 weeks), where only the Zn content was significantly elevated by 38%. Since neuropathological changes in human Alzheimer's disease are presumed to occur years before the first cognitive symptoms appear, quantification of brain iron content could be a powerful marker for early diagnosis of Alzheimer's disease.

We investigated the life-cycle energy implications of amorphous silicon (a-Si) PV designs using a nanocrystalline silicon (nc-Si) bottom layer in the context of a comparative, prospective life-cycle analysis framework. Three R&D options using nc-Si bottom layer were evaluated and compared to the current triple-junction a-Si design, i.e., a-Si/a-SiGe/a-SiGe. The life-cycle energy demand to deposit nc-Si was estimated from parametric analyses of film thickness, deposition rate, precursor gas usage, and power for generating gas plasma. We found that extended deposition time and increased gas usages associated to the relatively high thickness of nc-Si lead to a larger primary energy demand for the nc-Si bottom layer designs, than the current triple-junction a-Si. Assuming an 8% conversion efficiency, the energy payback time of those R&D designs will be 0.7-0.9 years, close to that of currently commercial triple-junction a-Si design, 0.8 years. Future scenario analyses show that if nc-Si film is deposited at a higher rate (i.e., 2-3 nm/s), and at the same time the conversion efficiency reaches 10%, the energy-payback time could drop by 30%.

Members of the species P. putida show a diverse spectrum of metabolic activities, which is indicative of their adaptation to various niches, which includes the ability to live in soils and sediments contaminated with high concentrations of heavy metals and organic contaminants. Pseudomonas putida strains are also found as plant growth-promoting rhizospheric and endophytic bacteria. The genome sequences of several P. putida species have become available and provide a unique tool to study the specific niche adaptation of the various P. putida strains. In this review, we compare the genomes of four P. putida strains: the rhizospheric strain KT2440, the endophytic strain W619, the aromatic hydrocarbon-degrading strain F1 and the manganese-oxidizing strain GB-1. Comparative genomics provided a powerful tool to gain new insights into the adaptation of P. putida to specific lifestyles and environmental niches, and clearly demonstrated that horizontal gene transfer played a key role in this adaptation process, as many of the niche-specific functions were found to be encoded on clearly defined genomic islands.

AN - 869815363; 14515115 AB - We investigated the effects on the growth of the anaerobic bacterium, Clostridium sp., of the ionic liquid, 1-methoxyethyl-3-methyl imidazolium [MOEMIM]+, derived from imidazolium cation and paired with one of a variety of counter-ions, viz., tetrafluoroborate [ BF 4 ] - , hexafluorophosphate [ PF 6 ] - , trifluoroacetate [ CF 3 COO ] - , bis(trifluoromethane)sulfonamide [ Tf 2 N ] - , methane sulfonate [OMS], and 1-butyl-3-methyl imidazolium tetrafluoroborate [BMIM][BF4]. These anions, in association with [MOEMIM]+ lowered the growth rate of the bacterium, showing the following trend: [ Tf 2 N ] - a[control] [ PF 6 ] - > [ BF 4 ] - > [ CF 3 COO ] - >[OMS]a degree . Anions incorporating fluorine were more toxic than those without it, and their toxicity rose with an increase in the number of fluorine atoms. Also, [MOEMIM]+ [ BF 4 ] - was less toxic than [BMIM]+ [ BF 4 ] - , probably due to the presence of a methoxyethyl functional group integrated in the cation side chain.

In the presence of 0.5- and 1% of [BMIM][PF6] or [EtPy][CF3COO] the growth of bacteria was inhibited, whereas exposing them to 1% [EtPy][BF4] increased the lag period wherein bacteria adapt to growth conditions before continuing to grow. However, at higher concentrations (5% and 10%), no growth was observed. The inhibitory effects were evident by a decrease in the optical density of the culture, a decline in the consumption of the carbon source, citric acid, and a change in the size of the bacterium. At concentrations below 1%, [EtPy][BF4] was metabolized by P. fluorescens in the presence of citric acid. Oxidation of the side alkyl-chain of [EtPy][BF4] caused the accumulation of N-hydroxylethylpyridinium and pyridinium as major degradation products.

They are similar in sequence to fatty acyl-coenzyme A (CoA) ligases (FACLs). However, while FACLs perform a two-step catalytic reaction, AMP ligation followed by CoA ligation using ATP and CoA as cofactors, FAALs produce only the acyl adenylate and are unable to perform the second step. We report X-ray crystal structures of full-length FAAL from Escherichia coli (EcFAAL) and FAAL from Legionella pneumophila (LpFAAL) bound to acyl adenylate, determined at resolution limits of 3.0 and 1.85 Aa, respectively. The structures share a larger N-terminal domain and a smaller C-terminal domain, which together resemble the previously determined structures of FAAL and FACL proteins. Our two structures occur in quite different conformations. EcFAAL adopts the adenylate-forming conformation typical of FACLs, whereas LpFAAL exhibits a unique intermediate conformation. Both EcFAAL and LpFAAL have insertion motifs that distinguish them from the FACLs. Structures of EcFAAL and LpFAAL reveal detailed interactions between this insertion motif and the interdomain hinge region and with the C-terminal domain. We suggest that the insertion motifs support sufficient interdomain motions to allow substrate binding and product release during acyl adenylate formation, but they preclude CoA binding, thereby preventing CoA ligation.

However, the neurobiological effects by which MPH improves cognition are still poorly understood. Here, functional magnetic resonance imaging (fMRI) was used together with working memory (WM) and visual attention (VA) tasks to test the hypothesis that 20 mg oral MPH would increase activation in the dorsal attention network (DAN) and deactivation in the default mode network (DMN) as well as improve performance during cognitive tasks in healthy men. The group of subjects that received MPH (MPH group; N = 16) had higher activation than the group of subjects who received no medication (control group: N = 16) in DAN regions (parietal and prefrontal cortex, regions increasingly activated with increased cognitive load) and had increased deactivation in the insula and posterior cingulate cortex (regions increasingly deactivated with increased cognitive load) and these effects did not differ for the VA and the WM tasks. These findings provide the first evidence that MPH enhances activation of the DAN whereas it alters DMN deactivation. This suggests that MPH (presumably by amplifying dopamine and noradrenergic signaling) modulates cognition in part through its effects on DAN and DMN.

The degree of the framework collapse indicated by the unit-cell volume contraction depends on the size of the non-framework cation: K-exchanged natrolite undergoes an 18.8% unit-cell volume contraction when dehydrated at 175 degrees C, whereas Rb- and Cs-exchanged natrolites show unit-cell volume contractions of 18.5 and 15.2% at 150 and 100 degrees C, respectively. In the hydrated phases, the dehydration-induced unit-cell volume reduction diminishes as the cation size increases and reveals increasingly a negative slope as smaller cations are substituted into the pores of the natrolite structure. The thermal expansion of the unit-cell volumes of the dehydrated K-, Rb-, and Cs-phases have positive thermal expansion coefficients of 8.80X10 (super -5) K (super -1) , 1.03X10 (super -4) K (super -1) , and 5.06X10 (super -5) K (super -1) , respectively. Rietveld structure refinements of the dehydrated phases at 400 degrees C reveal that the framework collapses are due to an increase of the chain rotation angles, psi , which narrow the channels to a more elliptical shape. Compared to their respective hydrated structures at ambient conditions, the dehydrated K-exchanged natrolite at 400 degrees C shows a 2.2-fold increase in psi , whereas the dehydrated Rb- and Cs-natrolites at 400 degrees C reveal increases of psi by ca. 3.7 and 7.3 times, respectively. The elliptical channel openings of the dehydrated K-, Rb-, to Cs-phases become larger as the cation size increases. The disordered non-framework cations in the hydrated K-, Rb-, and Cs-natrolite order during dehydration and the subsequent framework collapse. The dehydrated phases of Rb- and Cs-natrolite can be stabilized at ambient conditions.

To learn more about metals in ALS, we determined the metallation states of human wild-type or mutant (G37R, G93A, and H46R/H48Q) SOD1 proteins from SOD1-ALS transgenic mice spinal cords. SOD1 was gently extracted from spinal cord and separated into insoluble (aggregated) and soluble (supernatant) fractions, and then metallation states were determined by HPLC inductively coupled plasma MS. Insoluble SOD1-rich fractions were not enriched in copper and zinc. However, the soluble mutant and WT SOD1s were highly metallated except for the metal-binding-region mutant H46R/H48Q, which did not bind any copper. Due to the stability conferred by high metallation of G37R and G93A, it is unlikely that these soluble SOD1s are prone to aggregation in vivo, supporting the hypothesis that immature nascent SOD1 is the substrate for aggregation. We also investigated the effect of SOD1 overexpression and disease on metal homeostasis in spinal cord cross-sections of SOD1-ALS mice using synchrotron-based x-ray fluorescence microscopy. In each mouse genotype, except for the H46R/H48Q mouse, we found a redistribution of copper between gray and white matters correlated to areas of high SOD1. Interestingly, a disease-specific increase of zinc was observed in the white matter for all mutant SOD1 mice. Together these data provide a picture of copper and zinc in the cell as well as highlight the importance of these metals in understanding SOD1-ALS pathology.

Skin, particularly the epidermis, consisting mainly of keratinocytes with potential for proliferation and malignant transformation, absorbs the majority of the radiation dose. Therefore, we used normal human keratinocytes to investigate and quantify the DNA damage caused by secondary radiation. Its manifestation depends on the presence of retinol in the serum-free media, and is regulated by phosphatidylinositol 3-kinases. We simulated the generation of secondary radiation after the impact of protons and iron ions on an aluminum shield. We also measured the intensity and the type of the resulting secondary particles at two sample locations; our findings agreed well with our predictions. We showed that secondary particles inflict DNA damage to different extents, depending on the type of primary radiation. Low-energy protons produce fewer secondary particles and cause less DNA damage than do high-energy protons. However, both generate fewer secondary particles and inflict less DNA damage than do high mass and energy ions. The majority of cells repaired the initial damage, as denoted by the presence of 53BPI foci, within the first 24 hours after exposure, but some cells maintained the 53BP1 foci longer.

In this work, we evaluated the concordance between the new INS (inelastic neutron scattering) technology and the DC method. The comparisons were carried out in the high C content (30-40%) organic soils of Willard, Ohio (4 sites), in natural forest in Willard, Ohio (1 site), and in a watershed pasture, with a approximately 10 degrees slope, in Coshocton, Ohio (5 sites). In addition to these stationary measurements, the organic soil and the pasture were continuously scanned with the inelastic neutron scattering (INS) system to obtain the transects' mean C value. Both types of measurements, INS and DC, registered a decline in the surface density of C along transects in the watershed and in the organic soil. Similarly, both recorded a drop in C in the organic soil of about 0.16%. In the pastureland, declines in C levels of 0.08% and 0.10% were observed, respectively, by DC and INS. Combining the results from the three sites yielded a very satisfactory correlation between the INS- and DC-responses, with a regression coefficient, r (super 2) , value of about 0.99. This suggests the possibility of establishing a universal regression line for various soil types. In addition, we demonstrated the ability of INS to measure the mean value over transect. In organic soil the mean value of an INS scan agreed, approximately 0.5%, with the mean values of the DC analysis, whereas large discrepancy between these two was recorded in the pastureland. Overall, the various trends observed in C measurements by INS concurred with those determined by the DC method, so enhancing the confidence in the new INS technology.

Sensitivities included the use of empirically derived relations to calculate the slope parameter and diagnose the intercept parameter of the exponential snow and rain size distributions and sensitivities to the treatment of hail/graupel. A detailed evaluation of the experiments against various high temporal resolution and spatially distributed observational data was performed to understand how moist processes responded to the implemented size distribution modifications. Net vapour consumption by microphysical processes was found to be unaffected by snow or rain size distribution modifications, while it was reduced replacing formulations for hail by those typical for graupel, mainly due to intense sublimation of graupel. Cloud optical thickness was overestimated in all experiments and all cases, likely due to overestimated snow amounts. The overestimation slightly deteriorated by modifying the rain and snow size distributions due to increased snow depositional growth, while it was reduced by including graupel. The latter was mainly due to enhanced cloud water collection by graupel and reduced snow depositional growth. Radar reflectivity and cloud optical thickness could only be realistically represented by inclusion of graupel during a stratiform case, while hail was found indispensable to simulate the vertical reflectivity profile and the surface precipitation structure. Precipitation amount was not much altered by any of the modifications made and the general overestimation was only decreased slightly during a supercell convective case.

However, some of this chemical variety may be due to contamination or alteration during particle capture in aerogel. We investigated six carbonaceous Stardust samples that had been previously analyzed and six new samples from Stardust Track 80 using correlated transmission electron microscopy (TEM), X-ray absorption near-edge structure spectroscopy (XANES), and secondary ion mass spectroscopy (SIMS). TEM revealed that samples from Track 35 containing abundant aliphatic XANES signatures were predominantly composed of cometary organic matter infilling densified silica aerogel. Aliphatic organic matter from Track 16 was also observed to be soluble in the epoxy embedding medium. The nitrogen-rich samples in this study (from Track 22 and Track 80) both contained metal oxide nanoparticles, and are likely contaminants. Only two types of cometary organic matter appear to be relatively unaltered during particle capture. These are (1) polyaromatic carbonyl-containing organic matter, similar to that observed in insoluble organic matter (IOM) from primitive meteorites, interplanetary dust particles (IDPs), and in other carbonaceous Stardust samples, and (2) highly aromatic refractory organic matter, which primarily constitutes nanoglobule-like features. Anomalous isotopic compositions in some of these samples also confirm their cometary heritage. There also appears to be a significant labile aliphatic component of Wild 2 organic matter, but this material could not be clearly distinguished from carbonaceous contaminants known to be present in the Stardust aerogel collector.

This study aims at understanding of how biofilm formation changes the mineral surface. Adhesion and mechanical properties (e.g. elastic modulus) were investigated by atomic force microscopy (AFM), while the chemical composition of the biofilm was mapped by scanning transmission X-ray microscopy (STXM). We investigated single-layered biofilms formed by Bacillus subtilis on Lysogeny broth-agar plates in the presence or absence of goethite. Synchrotron-based STXM C K-edge image sequences, recorded at a spatial resolution of < or =25 nm, were converted to component maps of proteins, polysaccharides, nucleic acids and lipids by linear combination fitting. STXM revealed that proteins, nucleic acids and lipids were mainly located inside the cells, while polysaccharides dominate in the extracellular polymeric substances (EPS). In the presence of goethite, we found a higher concentration of nucleic acids in the EPS and the goethite needles were covered by nucleic acids. This supports the view that nucleic acids mediate EPS binding to mineral surfaces and are required for establishing biofilms. Quantitative nanomechanical properties measurement by AFM indicated that the DMT modulus (elastic modulus) of the goethite surface decreased from approximately 40 GPa to approximately 84 MPa after biofilm formation. The adhesion between the AFM tip and the goethite surface in air increased from approximately 2 nN to approximately 12 nN after biofilm formation. We hypothesize that nucleic acids are intentionally excreted by B. subtilis when e.g. goethite surfaces are present. This preferentially adsorbed nucleic acid-rich material is responsible for the observed changes in the mechanical surface properties of goethite.

Typically XPS measurments are performed under ultra-high vacuum conditions, which are far removed from many environmental or technologically relevant conditions. The development of synchrotron based Ambient Pressure XPS (AP-XPS) that incorporates a differentially pumped electrostatic lens system into the electron energy analyzer has made possible XPS measurments at pressure up to about 5 Torr. In this presentation, after a brief introduction to the AP-XPS technique, results using AP-XPS to investigate the reduction of a chemisorbed oxygen layer on Ni (100) by hydrogen will be discussed. Among transition metal oxides, NiO has been the focus of extensive fundamental studies due to its applications in catalysis and potential magnetic devices. The reduction of NiO has been studied at elevated pressure conditions using a broad range of techniques including X-ray Diffraction [1], and Near Edge X-ray Absorbtion Spectroscopy [2] among others. Relatively unexplored is the reduction of chemisorbed oxygen on the surfaces of Ni single crystals at elevated pressures. We have investigated the reduction of the c (2X2)-O chemisorbed layer on Ni (100) using AP-XPS at temperatures from 100 degrees C to 150 degrees C and pressures up to 0.5 Torr. The presence of small NiO clusters, located at step edges as shown by scanning tunneling microscopy, have a significant impact on the reduction kinetics of the c (2X2)-O layer. These clusters are preferentially reduced compared to the c (2X2)-O layer and increase the reduction rate of the c (2X2)-O layer, quite likely from spill-over of dissociated hydrogen from the NiO islands.

Both the section and the SCMT images show that sulfides melt, coalesce, and migrate to the MMs surface. The decomposition of sulfides may occur during all these stages. Given the sulfide morphologies and compositions that we see in section, we think the breakdown of Ni sulfides produces the FeNi beads. The SCMT images show that metal beads are common in melted MMs, >50% have them. Vesicles in porphyritic and scoriaceous MMs are also probably formed as sulfides decompose. Not only do sulfides abut the vesicles but also the temperatures at which sulfides decompose overlap those at which MM surfaces first melt and temporarily seal, suggesting that S gases could produce most of these vesicles. As the vesicle shapes and patterns of distribution differ among MM classes, tomography can be used to nondestructively screen for specific types of MMs. Tomography is a powerful tool for visualizing the three-dimensional distribution of metal beads, sulfides, mean densities, and vesicles in MMs. JF - Meteoritics & Planetary Science AU - Taylor, Susan AU - Jones, Keith W AU - Herzog, Gregory F AU - Hornig, Claire E Y1 - 2011 PY - 2011 DA - 2011 SP - 1498 EP - 1509 PB - Meteoritical Society, Fayetteville, AR VL - 46 IS - 10 SN - 1086-9379, 1086-9379 KW - vesicular texture KW - tomography KW - synchrotron computed microtomography KW - iron-nickel alloys KW - textures KW - nickel sulfides KW - microstructure KW - cosmic spherules KW - melts KW - gases KW - electron probe data KW - morphology KW - visualization KW - micrometeorites KW - meteorites KW - computed tomography KW - metals KW - nickel KW - sulfur KW - alloys KW - sulfides KW - 05B:Petrology of meteorites and tektites UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1287375255?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Meteoritics+%26+Planetary+Science&rft.atitle=Tomography%3B+a+window+on+the+role+of+sulfur+in+the+structure+of+micrometeorites&rft.au=Taylor%2C+Susan%3BJones%2C+Keith+W%3BHerzog%2C+Gregory+F%3BHornig%2C+Claire+E&rft.aulast=Taylor&rft.aufirst=Susan&rft.date=2011-01-01&rft.volume=46&rft.issue=10&rft.spage=1498&rft.isbn=&rft.btitle=&rft.title=Meteoritics+%26+Planetary+Science&rft.issn=10869379&rft_id=info:doi/10.1111%2Fj.1945-5100.2011.01245.x L2 - http://cavern.uark.edu/~meteor/ LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2013, American Geosciences Institute.

The diffraction data for types II(sII) and H(sH) were refined to the known structures with space groups Fd3m and P63/mmc, respectively. Upon compression, sI methane hydrate transforms to the sII phase at 120 MPa, and then to the sH phase at 600 MPa. The sII methane hydrate was found to coexist locally with sI phase up to 500 MPa and with sH phase up to 600 MPa. The pure sH structure was found to be stable between 600 and 900 MPa. Methane hydrate decomposes at pressures above 3 GPa to form methane with the orientationally disordered Fm3m structure and ice VII(Pn3m). The results highlight the role of guest(CH (sub 4) )-host(H (sub 2) O) interactions in the stabilization of the hydrate structures under pressure.

Murshidabad, an eastern district in West Bengal, India, where groundwaters are highly As-affected (up to approximately 4000 mu g/l), was chosen as our study area. Objectives were: (1) characterize sediment cores and groundwaters in areas with contrasting As concentrations; (2) describe the extent of spatial variability of dissolved As concentrations in shallow (<60 m) aquifers; (3) identify source (s) of aquifer recharge to understand the bioavailability and mobilization of As from sediments to groundwaters. Surface (0-2m) and core (2-40m) sediments and water from shallow and deep tubewells, irrigation, ponds, and major rivers were collected during two field seasons. The low-As Pleistocene terrace sediments are orange-brown, whereas the high-As Holocene floodplain sediments are grey. Mineralogical examination reveals the Pleistocene sediments as mainly quartz and feldspars coated with Fe (III) oxides/hydroxides, whereas the Holocene sediments also contain clay minerals, micas, amphiboles, carbonates, and accessories. Sequential extractions show As present chiefly in specifically-sorbed phases and associated with amorphous and poorly-crystalline hydrous oxides of Fe (Al and Mn). Hydrochemistry shows reducing conditions in high-As waters (high Fe, HCO (sub 3) (super -) , PO (sub 4) (super 3-) , NH (sub 4) (super +) , As (III):As (sub T) ; low NO (sub 3) (super -) , NO (sub 2-) , Cl (sub -) , SO (sub 4) (super 2-) ); low-As areas showed converse relationships with these values. The complex spatial variability of dissolved As levels may result from variable flow paths induced by well-pumping and seasonal flooding, buried As-rich lenses, distribution of microbial communities, etc. Stable isotope values for delta (super 2) H and delta (super 18) O in water samples plot on the local meteoric water line between summer monsoon and dry season precipitation, indicating the high As groundwater originates as local precipitation that has not experienced any appreciable evaporation. Furthermore, the stable isotopes demonstrate that the high As groundwaters are not recharged by local pond waters, which have undergone substantial evaporation.

The current status of the knowledge on the primary SSA production flux, mainly for particles with r (sub 80) (equilibrium radius at 80% relative humidity) less than 1 mu m, has recently been reviewed by de Leeuw et al. (2011). These authors discussed the production of sea-spray particles and its dependence on controlling factors which have been investigated in laboratory studies that have examined the dependences on water temperature, salinity, and the presence of organics, and in field measurements with micrometeorological techniques that use newly developed fast optical particle sizers. Extensive measurements show that water-insoluble organic matter contributes substantially to the composition of SSA particles with r (sub 80) < 0.25 mu m and in locations with high biological activity can be the dominant constituent. Order-of-magnitude variation remains in estimates of the size-dependent production flux per white area, the quantity central to formulations of the production flux based on the whitecap method. This variation indicates that the production flux may depend on quantities, such as the volume flux of air bubbles to the surface, that are not accounted for in current models. Variation in estimates of the whitecap fraction as a function of wind speed contributes additional, comparable uncertainty to production flux estimates. de Leeuw et al. (2011) conclude that despite the many gains in understanding in recent years, the uncertainty in the SSA production flux remains sufficiently great that present knowledge of this quantity cannot usefully constrain the representation of emissions of SSA in chemical transport models or climate models that include aerosols. As a consequence it is not yet possible to improve the modeling of these emissions much beyond the current state of affairs which shows nearly two orders of magnitude spread in current estimates of global annual SSA emissions.

Using experimental and theoretical probes of the local structure, we demonstrate this behavior in binary lead chalcogenides, which were believed to adopt the ideal, undistorted rock-salt structure at all temperatures. The behavior is consistent with a simple thermodynamic model in which the emerging dipoles are stabilized in the disordered state at high temperature due to the extra configurational entropy despite the fact that the undistorted structure has lower internal energy. Our findings shed light on the anomalous electronic and thermoelectric properties of the lead chalcogenides. Similar searches may show that the phenomenon is more widespread.

Zrt-, Irt-like proteins (ZIPs) represent a major route for entry of zinc ions into cells, but how ZIPs promote zinc uptake has been unclear. Here we report the molecular characterization of ZIPB from Bordetella bronchiseptica, the first ZIP homolog to be purified and functionally reconstituted into proteoliposomes. Zinc flux through ZIPB was found to be nonsaturable and electrogenic, yielding membrane potentials as predicted by the Nernst equation. Conversely, membrane potentials drove zinc fluxes with a linear voltage-flux relationship. Direct measurements of metal uptake by inductively coupled plasma mass spectroscopy demonstrated that ZIPB is selective for two group 12 transition metal ions, Zn2+ and Cd2+, whereas rejecting transition metal ions in groups 7 through 11. Our results provide the molecular basis for cellular zinc acquisition by a zinc-selective channel that exploits in vivo zinc concentration gradients to move zinc ions into the cytoplasm.

However, the bacterial analog of ubiquitin, prokaryotic ubiquitin-like protein (Pup), is an intrinsically disordered protein that bears little sequence or structural resemblance to the highly structured ubiquitin. Thus, it was unknown how pupylated proteins were recruited to the proteasome. Here, we show that the Mycobacterium proteasomal ATPase (Mpa) has three pairs of tentacle-like coiled coils that recognize Pup. Mpa bound unstructured Pup through hydrophobic interactions and a network of hydrogen bonds, leading to the formation of an alpha -helix in Pup. Our work describes a binding-induced folding recognition mechanism in the Pup-proteasome system that differs mechanistically from substrate recognition in the ubiquitin-proteasome system. This key difference between the prokaryotic and eukaryotic systems could be exploited for the development of a small molecule-based treatment for tuberculosis.

This acidification has the potential to enhance water-rock interactions such as dissolution and precipitation of carbonate minerals. As a result, the integrity of the caprock may be altered by the acidified brine, thereby affecting the potential for leakage of the injected CO<2) . To investigate the impact of leakage of CO<2) -acidified brine through caprock fractures, a flow-through experiment was conducted on a fractured sample of caprock. This caprock is a specimen of the Amherstburg formation in the Michigan sedimentary basin, and is a fine-grained carbonate composed primarily of calcite and dolomite. This formation overlies the Bass Islands Dolostone, the target formation for an injection demonstration project. The core sample was artificially fractured prior to the experiment and incased in epoxy to prevent lateral flow. Experimental temperature and pressure conditions were 40°C and 10 MPa, corresponding to injection at depths of approximately 1 km. The initial brine composition was representative of water previously reacted with the injection formation minerals under CO<2) -saturated conditions. The flow-through experiment was conducted within a medical-grade CT scanner allowing for continued scanning of the core during active injection. Additionally, pre- and post-injection scans were taken with a micro-CT scanner providing voxel resolution of 27 µm, roughly five times better than that achieved via the medical scanner. Mineral dissolution along the fracture network is evident in both the CT imaging and analysis of brine effluent composition. After one week of brine flow, the micro-CT scans show increases in fracture aperture as large as 2 mm which in some cases is more than a 20-fold increase in aperture width. Further work will apply synchrotron-based x-ray diffraction CT and x-ray fluorescence imaging methods in an attempt to couple geochemical and spatial alterations within single pores along a flowpath. The ability to observe geochemical reactions at different scales provides the unique opportunity to relate how mineral dissolution and precipitation at the pore-scale impacts core-scale flow characteristics relevant to understanding the evolution of caprock integrity.

A systematic decrease in Ti-in-quartz solubility occurs between 5 and 20 kbar. Titanium K-edge X-ray absorption near-edge structure (XANES) measurements demonstrate that Ti (super 4+) substitutes for Si (super 4+) on fourfold tetrahedral sites in quartz at all conditions studied. Molecular dynamic simulations support XANES measurements and demonstrate that Ti incorporation onto fourfold sites is favored over interstitial solubility mechanisms. To account for the P-T dependence of Ti-in-quartz solubility, a least-squares method was used to fit Ti concentrations in quartz from all experiments to the simple expression RTlnX (sub yiO2) (super quartz) = -60952 = 1.520 . t(K) - 1741.P(kbar) + RTlna (sub TiO2) where R is the gas constant 8.3145 J/K, T is temperature in Kelvin, X (sub TiO2) (super quartz) is the mole fraction of TiO (sub 2) in quartz and a (sub TiO2) is the activity of TiO (sub 2) in the system. The P-T dependencies of Ti-in-quartz solubility can be used as a thermobarometer when used in combination with another thermobarometer in a coexisting mineral, an independent P or T estimate of quartz crystallization, or well-constrained phase equilibria. If temperature can be constrained within + or -25 degrees C, pressure can be constrained to approximately + or -1.2 kbar. Alternatively, if pressure can be constrained to within + or -1 kbar, then temperature can be constrained to approximately + or -20 degrees C.

AN - 861987468; 2011-036089 AB - The mantle X-discontinuity, usually assigned to positive seismic velocity reflectors in the 260-330 km depth range, has proved difficult to explain in terms of a single mineralogical phase transformation in part because of its depth variability. The coesite to stishovite transition of SiO (sub 2) matches deeper X-discontinuity depths but requires 5-10% free silica in the mantle to match observed impedance contrast. The orthoenstatite (OEn) to high-pressure clinoenstatite (HPCen) transformation of MgSiO (sub 3) also broadly coincides with depths of the X but requires chemically depleted and orthoenstatite-rich lithology at 300 km depth in order to match observed seismic impedance contrast. On the basis of high-pressure infrared spectroscopy, X-ray diffraction, and Raman spectroscopy, we show that 1300 ppm variation of H (sub 2) O content in MgSiO (sub 3) can displace the transition of low-pressure clinoenstatite (LPCen) to HPCen by up to 2 GPa, similar to previous quench experiments on the OEn to HPCen phase transition, where about 30-45 km (1.0-1.5 GPa) of deflection could occur per 0.1 wt% H (sub 2) O. If the mantle X-discontinuity results from pyroxene transitions in a depleted harzburgite layer, because of the strong influence of minor amounts of water on the transformation boundary, the depth of the mantle X-discontinuity could serve as a potentially sensitive indicator of water content in the upper mantle.

The radioactive isotope super(11)C (t sub(1/2) 20.4 min), administered to intact leaves of Nicotiana tabacum L. (cv Samsun) as super(11)CO sub(2) gas enabled us to measure changes in new carbon partitioning into soluble sugar and amino acid pools of [ super(11)C]photosynthate. A 500 mu M MeJA treatment resulted in a decrease in the [ super(11)C]soluble sugar pool and an increase in the [ super(11)C]amino acid pool after 4 h. This pattern was more pronounced 15 h after treatment. We also examined the timeline for super(11)C-partitioning into aromatic amino acid metabolites of the shikimate pathway. [ super(11)C]Tyrosine, [ super(11)C]phenylalanine and [ super(11)C]tryptophan were elevated 1.5-fold, 12-fold and 12-fold, respectively, relative to controls, 4 h after MeJA treatment, while endogeneous pools were unchanged. This suggests that only new carbon is utilized during early stages of defense induction. By 15 h, [ super(11)C]tyrosine and [ super(11)C]phenylalanine returned to baseline while [ super(11)C]tryptophan was elevated 30-fold, suggesting that MeJA exerts selective control over the shikimate pathway. Finally, we measured trans-cinnamic acid levels as a gauge of downstream phenolic metabolism. Levels were unchanged 4 h after MeJA treatment relative to controls, but were increased 2-fold by 15 h, indicating a lag in response of secondary metabolism.

The structure of (H (sub 3) O)Fe(SO (sub 4) ) (sub 2) is found to be the same as a recently reported structure determined from single-crystal diffraction by Peterson et al. (2009), who synthesized the same compound using a hydrothermal method. The phase boundary between rhomboclase and (H (sub 3) O)Fe(SO (sub 4) ) (sub 2) as a function of temperature (T) and relative humidity (RH) was determined by environment-controlled in situ X-ray diffraction (XRD) method. The stability of (H (sub 3) O)Fe(SO (sub 4) ) (sub 2) against rhomboclase was further evaluated under a simulated martian condition (constant 50% RH, -20 degrees C, 6 mbar CO (sub 2) ). Both phases remained after 14 days with no observable transition. This result suggests that hydrate ferric sulfate minerals might not respond to diurnal RH fluctuation under the extremely slowed kinetics expected on the martian surface.

However, there is a scarcity of data on upstream water factors and discrepancies of data from different sources. We reviewed previous studies of water use in electricity generation and used full-life cycle accounting to evaluate water demand factors, both withdrawal and consumption, for conventional- and renewable-electrical power plants. Our investigation showed that moving to technologies like photovoltaics and wind offers the best option for conserving our water supply. We also emphasize the importance of employing a transparent, balanced approach in accounting life-cycle water usages.

Additional work is required to establish a proper conversion factor of INS readings to conventional units. a- The INS system has the potential to detect smaller changes in soil elemental composition than is currently possible with conventional methods. Forest soils are pivotal to understanding global carbon (C) cycling and evaluating policies for mitigating global change. However, they are very difficult to monitor because of the heterogeneity of soil characteristics, the difficulty of representative sampling, and the slow time scale of response to environmental change. Here we demonstrate that use of gamma-ray spectroscopy facilitates in situ non-destructive analysis of C and other elements in forest soils. In this approach the element-specific gamma-rays are induced by fast and thermal neutrons interacting with the nuclei of the elements present in the soil. Background gamma-rays emanating from naturally occurring radionuclides in the forest are recorded as well. We applied this approach in a mature northern hardwood forest on glacial till soils at the Bartlett Experimental Forest in New Hampshire, USA. The inelastic neutron scattering (INS) system yielded strong signals in gamma-ray counts/h, from C and other elements present in the soil matrix that included silicon, oxygen, hydrogen, iron, aluminum, manganese and potassium. The INS sensitivity for carbon was 20.656 countsh super(-1) kg super(-1) Cm super(-2) based on current net C gamma-ray counts and the data for the O horizon and mineral soil to a depth of 30cm obtained from a nearby quantitative soil pit (7.35kgCm super(-2)). We estimate the minimum detectable change to be 140.34kgCm super(-2), which is 5% of the current soil C content, and the minimum detectable limit to be 0.23kgCm super(-2). Eight % reproducibility from 11 measurements was limited, in part, by the large variability in the system counting geometry due to the uneven forest microtopography. The INS approach has the potential to revolutionize belowground monitoring of C and other elements, because the possibility of detecting a 5% change in forest soils has not been possible with destructive sampling methods.

The aerosol size distribution and composition often showed strong diurnal variation associated with traffic emissions and aging of aerosols through coagulation and local photochemical production of secondary aerosol species. CCN concentrations (N sub(CCN)) are derived using Koehler theory from the measured aerosol size distribution and various simplified aerosol mixing state and chemical composition, and are compared to concurrent measurements at five supersaturations ranging from 0.11% to 0.35%. The influence of assumed mixing state on calculated N sub(CCN) is examined using both aerosols observed during MILAGRO and representative aerosol types. The results indicate that while ambient aerosols often consist of particles with a wide range of compositions at a given size, N sub(CCN) may be derived within ~20% assuming an internal mixture (i.e., particles at a given size are mixtures of all participating species, and have the identical composition) if great majority of particles has an overall (hygroscopicity parameter) value greater than 0.1. For a non-hygroscopic particle with a diameter of 100 nm, a 3 nm coating of sulfate or nitrate is sufficient to increase its from 0 to 0.1. The measurements during MILAGRO suggest that the mixing of non-hygroscopic primary organic aerosol (POA) and black carbon (BC) particles with photochemically produced hygroscopic species and thereby the increase of their to 0.1 take place in a few hours during daytime. This rapid process suggests that during daytime, a few tens of kilometers away for POA and BC sources, N sub(CCN) may be derived with sufficient accuracy by assuming an internal mixture, and using bulk chemical composition. The rapid mixing also indicates that, at least for very active photochemical environments such as Mexico City, the timescale during daytime for the conversion of hydrophobic POA and BC to hydrophilic particles is substantially shorter than the 1-2 days used in some global models. The conversion time scale is substantially longer during night. Most POA and BC particles emitted during evening hours likely remain non-hygroscopic until efficiently internally mixed with secondary species in the next morning. The results also suggest that the assumed mixing state strongly impacts calculated N sub(CCN) only when POA and BC represent a large fraction of the total aerosol volume. One of the implications is that while physically unrealistic, external mixtures, which are used in many global models, may also sufficiently predict N sub(CCN) for aged aerosol, as the contribution of non-hygroscopic POA and BC to overall aerosol volume is often substantially reduced due to the condensation of secondary species.

AN - 733997469; 20552213 AB - DNA-damaging agents can induce clustered lesions or multiply damaged sites (MDSs) on the same or opposing DNA strands. In the latter, attempts to repair MDS can generate closely opposed single-strand break intermediates that may convert non-lethal or mutagenic base damage into double-strand breaks (DSBs). We constructed a diploid S. cerevisiae yeast strain with a chromosomal context targeted by integrative DNA fragments carrying different damages to determine whether closely opposed base damages are converted to DSBs following the outcomes of the homologous recombination repair pathway. As a model of MDS, we studied clustered uracil DNA damages with a known location and a defined distance separating the lesions. The system we describe might well be extended to assessing the repair of MDSs with different compositions, and to most of the complex DNA lesions induced by physical and chemical agents.

13401024 AB - Angle-resolved photoemission has developed into one of the leading probes of the electronic structure and associated dynamics of condensed matter systems. As with any experimental technique the ability to resolve features in the spectra is ultimately limited by the resolution of the instrumentation used in the measurement. Previously developed for sharpening astronomical images, the Lucy-Richardson deconvolution technique proves to be a useful tool for improving the photoemission spectra obtained in modern hemispherical electron spectrometers where the photoelectron spectrum is displayed as a 2D image in energy and momentum space.

Mtb requires the proteasome to resist killing by the host immune system. The detailed assembly process and the gating mechanism of Mtb proteasome have remained unknown. Using cryo-electron microscopy and X-ray crystallography, we have obtained structures of three Mtb proteasome assembly intermediates, showing conformational changes during assembly, and explaining why the b-subunit propeptide inhibits rather than promotes assembly. Although the eukaryotic proteasome core particles close their protein substrate entrance gates with different amino terminal peptides of the seven a-subunits, it has been unknown how a prokaryotic proteasome might close the gate at the symmetry axis with seven identical peptides. We found in the new Mtb proteasome crystal structure that the gate is tightly sealed by the seven identical peptides taking on three distinct conformations. Our work provides the structural bases for assembly and gating mechanisms of the Mtb proteasome.

13251810 AB - Phytochromes are a collection of dimeric photoreceptors that direct a diverse array of responses in plants and microorganisms through photoconversion between a red light-absorbing ground state Pr, and a far-red light-absorbing photoactivated state Pfr. Photoconversion from Pr to Pfr is initiated by a light-driven rotation within the covalently attached bilin, which then triggers a series of protein conformational changes in the binding pocket. These movements ultimately affect an appended output module, which often has reversible protein kinase activity. Propagation of the light signal from the bilin to the output module likely depends on the dimerization interface but its architecture and response to phototransformation remain unclear. Here, we used single particle cryoelectron microscopy to determine the quaternary arrangement of the phytochrome dimer as Pr, using the bacteriophytochrome (BphP) from Deinococcus radiodurans. Contrary to the long-standing view that the two monomers are held together solely via their C-terminal region, we provide unambiguous evidence that the N-terminal bilin-binding region of BphP also provides a dimerization interface with the C-terminal kinase domain appearing as a more flexible appendage. The BphP monomers dimerize in parallel with the polypeptides intimately twisting around each other in a right-handed fashion. Based on this electron microscopic picture, we propose that the light-driven conformational changes transmitted from the chromophore to the output module along the spine of this extensive dimer interface is the central feature underpinning phytochrome signaling.

To examine the temporal and anatomical profile of neuroinflammation and NMDA receptors (NMDAR) in a stroke model, rats (N = 17) were subjected to a 90 min occlusion of the middle cerebral artery (MCAO) and compared to sham (N = 5) and intact (N = 4) controls. Striatal and parietal cortical infarction was confirmed by MRI 24 h after reperfusion. Animals were killed 14 or 30-40 days later and consecutive coronal cryostat sections were processed for quantitative autoradiography with the neuroinflammation marker [ super(3)H]PK11195 and the NMDAR antagonist [ super(3)H]MK801. Significantly increased specific binding of [ super(3)H]PK11195 relative to non-ischemic controls was observed in the ipsilateral striatum (> 3 fold, p 2 fold) with smaller (20%-80%) but statistically significant (p = 0.002-0.04) ipsilateral increases in other regions partially involved in the infarct such as the parietal and piriform cortex, and in the lateral septum, which was not involved in the infarct. Trends for increases in PBR density were also observed in the contralateral hemisphere. In the same animals, NMDAR specific binding was significantly decreased bilaterally in the septum, substantia innominata and ventral pallidum. Significant decreases were also seen in the ipsilateral striatum, accumbens, frontal and parietal cortex. The different anatomical distribution of the two phenomena suggests that neuroinflammation does not cause the observed reduction in NMDAR, though loss of NMDAR may be locally augmented in ipsilateral regions with intense neuroinflammation. Persistent, bilateral loss of NMDAR, probably reflecting receptor down regulation and internalization, may be responsible for some of the effects of stroke on cognitive function which cannot be explained by infarction alone.

AN - 733315880; 20408587 AB - We evaluated the cytotoxicity of various morphological classes of TiO(2) nanostructures (including 0-D nanoparticles, 1-D nanorods, and 3-D assemblies) toward living cells. These TiO(2) nanostructures were modified with fluorescent dye molecules, mediated via a dopamine linkage, in order to facilitate a confocal study of their internalization. Specifically, we noted that both TiO(2) 1-D nanorods and 0-D nanoparticles could internalize into cells after 24 h of incubation time. However, only incubation with TiO(2) 1-D nanorods and 3-D micrometer-scale sea urchin-like assemblies at concentrations of up to 125 microg/mL yielded data suggestive of cell viabilities of close to 100%. Moreover, upon irradiation with UV light for periods of a few minutes at energy densities of up to 1 J/cm(2), we observed up to 60% mortality rates, indicative of the cytotoxic potential of photoirradiated TiO(2) nanostructures due to the generation of reactive oxygen species.

H11-11), a potentially important biofuel feed stock plant. The Enterobacter sp. 638 genome sequence reveals the presence of a 4,518,712 bp chromosome and a 157,749 bp plasmid (pENT638-1). Genome annotation and comparative genomics allowed the identification of an extended set of genes specific to the plant niche adaptation of this bacterium. This includes genes that code for putative proteins involved in survival in the rhizosphere (to cope with oxidative stress or uptake of nutrients released by plant roots), root adhesion (pili, adhesion, hemagglutinin, cellulose biosynthesis), colonization/establishment inside the plant (chemiotaxis, flagella, cellobiose phosphorylase), plant protection against fungal and bacterial infections (siderophore production and synthesis of the antimicrobial compounds 4-hydroxybenzoate and 2-phenylethanol), and improved poplar growth and development through the production of the phytohormones indole acetic acid, acetoin, and 2,3-butanediol. Metabolite analysis confirmed by quantitative RT-PCR showed that, the production of acetoin and 2,3-butanediol is induced by the presence of sucrose in the growth medium. Interestingly, both the genetic determinants required for sucrose metabolism and the synthesis of acetoin and 2,3-butanediol are clustered on a genomic island. These findings point to a close interaction between Enterobacter sp. 638 and its poplar host, where the availability of sucrose, a major plant sugar, affects the synthesis of plant growth promoting phytohormones by the endophytic bacterium. The availability of the genome sequence, combined with metabolome and transcriptome analysis, will provide a better understanding of the synergistic interactions between poplar and its growth promoting endophyte Enterobacter sp. 638. This information can be further exploited to improve establishment and sustainable production of poplar as an energy feedstock on marginal, non-agricultural soils using endophytic bacteria as growth promoting agents. Poplar is considered as the model tree species for the production of lignocellulosic biomass destined for biofuel production. The plant growth promoting endophytic bacterium Enterobacter sp. 638 can improve the growth of poplar on marginal soils by as much as 40%. This prompted us to sequence the genome of this strain and, via comparative genomics, identify functions essential for the successful colonization and endophytic association with its poplar host. Analysis of the genome sequence, combined with metabolite analysis and quantitative PCR, pointed to a remarkable interaction between Enterobacter sp. 638 and its poplar host with the endophyte responsible for the production of a phytohormone, and a precursor for another that poplar is unable to synthesize, and where the production of the plant growth promoting compounds depended on the presence of plant synthesized compounds, such as sucrose, in the growth medium. Our results provide the basis to better understanding the synergistic interactions between poplar and Enterobacter sp. 638. This information can be further exploited to improve establishment and sustainable production of poplar on marginal, non-agricultural soils using endophytic bacteria such as Enterobacter sp. 638 as growth promoting agents.

AN - 746160745; 13137441 AB - The observed increase in global mean surface temperature (GMST) over the industrial era is less than 40% of that expected from observed increases in long-lived greenhouse gases together with the best-estimate equilibrium climate sensitivity given by the 2007 Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Possible reasons for this warming discrepancy are systematically examined here. The warming discrepancy is found to be due mainly to some combination of two factors: the IPCC best estimate of climate sensitivity being too high and/or the greenhouse gas forcing being partially offset by forcing by increased concentrations of atmospheric aerosols; the increase in global heat content due to thermal disequilibrium accounts for less than 25% of the discrepancy, and cooling by natural temperature variation can account for only about 15%. Current uncertainty in climate sensitivity is shown to preclude determining the amount of future fossil fuel CO sub(2) emissions that would be compatible with any chosen maximum allowable increase in GMST; even the sign of such allowable future emissions is unconstrained. Resolving this situation, by empirical determination of the earth's climate sensitivity from the historical record over the industrial period or through use of climate models whose accuracy is evaluated by their performance over this period, is shown to require substantial reduction in the uncertainty of aerosol forcing over this period.

The new Maia X-ray detector system provides a quantum leap for the method in terms of data acquisition rate. It is now possible to rapidly collect fully quantitative maps of the distribution of major and trace elements at micrometer spatial resolution over areas as large as 1X5 cm (super 2) . Fast data acquisition rates also open the way to X-ray absorption near-edge structure (XANES) imaging, in which spectroscopic information is available at each pixel in the map. These capabilities are critical for studying inhomogeneous Earth materials. Using a 96-element prototype Maia detector, we imaged thin sections of an oxidized pisolitic regolith (2X4.5 mm (super 2) at 2.5X2.5 mu m (super 2) pixel size) and a metamorphosed, sedimentary exhalative Mn-Fe ore (3.3X4 mm (super 2) at 1.25X5 mu m (super 2) ). In both cases, As K-edge XANES imaging reveals localized occurrence of reduced As in parts of these oxidized samples, which would have been difficult to recognize using traditional approaches.

In batch experiments, acetate-fed granular biofilms incubated aerobically reduced 0.2 mM Cr(VI) from a minimal medium at 0.15 mM day-1 g-1, with reduction of 0.17 mM day-1 g-1 under anaerobic conditions. There was negligible removal of Cr(VI) (i) without granular biofilms, (ii) with lyophilized granular biofilms, and (iii) with granules in the absence of an electron donor. Analyses by X-ray absorption near edge spectroscopy (XANES) of the granular biofilms revealed the conversion of soluble Cr(VI) to Cr(III). Extended X-ray absorption fine-structure (EXAFS) analysis of the Cr-laden granular biofilms demonstrated similarity to Cr(III) phosphate, indicating that Cr(III) was immobilized with phosphate on the biomass subsequent to microbial reduction. The sustained reduction of Cr(VI) by granular biofilms was confirmed in fed-batch experiments. Our study demonstrates the promise of granular-biofilm-based systems in treating Cr(VI)-containing effluents and wastewater.

To determine McrA's binding specificity, we cloned and expressed recombinant McrA with a C-terminal StrepII tag (rMcrA-S) to facilitate protein purification and affinity capture of human DNA fragments with m5C residues. Sequence analysis of a subset of these fragments and electrophoretic mobility shift assays with model methylated and unmethylated oligonucleotides suggest that N(Y > R) m5CGR is the canonical binding site for rMcrA-S. In addition to binding HpaII-methylated double-stranded DNA, rMcrA-S binds DNA containing a single, hemimethylated HpaII site; however, it does not bind if A, C, T or U is placed across from the m5C residue, but does if I is opposite the m5C. These results provide the first systematic analysis of McrA's in vitro binding specificity.

The results show that in the morning hours in the city center, the VOC distribution is dominated by non-methane hydrocarbons (NMHCs) but with a substantial contribution from oxygenated volatile organic compounds (OVOCs), predominantly from primary emissions. Alkanes account for a large part of the NMHC distribution in terms of mixing ratios. In terms of reactivity, NMHCs also dominate overall, especially in the morning hours. However, in the afternoon, as the boundary layer lifts and air is mixed and aged within the basin, the distribution changes as secondary products are formed. The WRF-Chem (Weather Research and Forecasting with Chemistry) model and MOZART (Model for Ozone and Related chemical Tracers) were able to approximate the observed MCMA daytime patterns and absolute values of the VOC OH reactivity. The MOZART model is also in agreement with observations showing that NMHCs dominate the reactivity distribution except in the afternoon hours. The WRF-Chem and MOZART models showed higher reactivity than the experimental data during the nighttime cycle, perhaps indicating problems with the modeled nighttime boundary layer height. A northeast transport event was studied in which air originating in the MCMA was intercepted aloft with the Department of Energy (DOE) G1 on 18 March and downwind with the National Center for Atmospheric Research (NCAR) C130 one day later on 19 March. A number of identical species measured aboard each aircraft gave insight into the chemical evolution of the plume as it aged and was transported as far as 1000 km downwind; ozone was shown to be photochemically produced in the plume. The WRF-Chem and MOZART models were used to examine the spatial extent and temporal evolution of the plume and to help interpret the observed OH reactivity. The model results generally showed good agreement with experimental results for the total VOC OH reactivity downwind and gave insight into the distributions of VOC chemical classes. A box model with detailed gas phase chemistry (NCAR Master Mechanism), initialized with concentrations observed at one of the ground sites in the MCMA, was used to examine the expected evolution of specific VOCs over a 1-2 day period. The models clearly supported the experimental evidence for NMHC oxidation leading to the formation of OVOCs downwind, which then become the primary fuel for ozone production far away from the MCMA.

This system underwent tests at a facility constructed specifically for testing, under controlled conditions, various detection systems for monitoring near-surface transport and accumulations of CO (sub 2) fluxes emanating from a shallow buried, slotted horizontal well. The INS System was assessed by comparing the results from placing it above the horizontal well at a spot with a known high CO (sub 2) leak identified and quantified the previous years, with those obtained from background readings adjacent to the well. At two different "Hot Spots", a suppression of about 14% in 2008 and about 7% in 2009 in carbon content above the well in comparison to the background signal was observed. An overview of these results is presented.

A slotted horizontal well divided into six zones was installed in the shallow subsurface. The scale and CO (sub 2) release rates were chosen to be relevant to developing monitoring strategies for geological carbon storage. The field site was characterized before injection, and CO (sub 2) transport and concentrations in saturated soil and the vadose zone were modeled. Controlled releases of CO (sub 2) from the horizontal well were performed in the summers of 2007 and 2008, and collaborators from six national labs, three universities, and the U.S. Geological Survey investigated movement of CO (sub 2) through the soil, water, plants, and air with a wide range of near surface detection techniques. An overview of these results will be presented.

There is ongoing debate about the differing health effects of asbestiform vs. non-asbestiform amphiboles, which can occur together with no apparent compositional differences. To help address these unresolved issues, we are studying the oxidation state of Fe in well-characterized amphiboles of both habits from the former vermiculite mine near Libby, Montana. The bulk sample of this amphibole is 65% Fe (super 3+) . X-ray absorption near-edge spectroscopy was used to measure Fe (super 3+) contents in one fragment, one puff-ball (randomly-oriented cryptocrystals), and two fibers. Each sample was mounted on a glass fiber inserted into an individual goniometer head. A polarizing light microscope was used to identify the X, Y, and Z optical orientations of each crystal, and three mutually-perpendicular directions for the puff-ball. The goniometer heads were taken to beamline X26A at the National Synchrotron Light Source, and mounted so that each crystallographic direction could be made to coincide with the incident polarized X-ray beam of the synchrotron. Using mutually-orthogonal Kirkpatrick-Baez silica mirrors to produce a focused beam of monochromatic x-rays <10 mu m in diameter, the structure of the Fe K absorption edge was scanned from 7080-8100 eV using a high resolution Si(311) monochromator. Pre-edge peaks were extracted and fit using Lorentzian lineshapes to determine their component peaks. All spectra of all samples in all orientations were dominated by a prominent peak with a centroid at 7114.33(3) eV; this likely represents Fe (super 3+) in all samples. In spectra of the puff-ball and the two fibers, the second-largest peak, was at approximately 7113.07(10) eV. In the fragment, the latter peak is present at lower energies (7112.30 in X and 7112.62 eV in Y); this shift suggests that the fragment is slightly more reduced than the fibers. This second peak is likely a combination of superimposed Fe (super 2+) and Fe (super 3+) contributions In two of the fiber samples, we can resolve structure in this composite peak, showing peaks at approximately 7113.03 eV and 7111.86 eV that might represent contributions from Fe (super 2+) and Fe (super 3+) , respectively. Overall, if the fibers represent the bulk Fe (super 3+) at 65% Fe (super 3+) , then these data suggest that the fragments might be approximately 50-55% Fe (super 3+) .

15118959 AB - Superoxide dismutases are enzymes that function to catalytically convert superoxide radical to oxygen and hydrogen peroxide. These enzymes carry out catalysis at near diffusion controlled rate constants via a general mechanism that involves the sequential reduction and oxidation of the metal center, with the concomitant oxidation and reduction of superoxide radicals. That the catalytically active metal can be copper, iron, manganese or, recently, nickel is one of the fascinating features of this class of enzymes. In this review, we describe these enzymes in terms of the details of their catalytic properties, with an emphasis on the mechanistic differences between the enzymes. The focus here will be concentrated mainly on two of these enzymes, copper, zinc superoxide dismutase and manganese superoxide dismutase, and some relatively subtle variations in the mechanisms by which they function.

The source of contamination was a plume that contained an estimated 7000kg of dissolved U that seeped into the subsurface as a result of an accident that occurred during filling of tank BX-102. The desorption character and kinetics of U were also determined by experiment in order to assess the mobility of U in the vadose zone. Most samples contained too little moisture to obtain quantitative information on pore water compositions. Concentrations of U (and contaminant phosphate-P) in pore waters were therefore estimated by performing 1:1 sediment-to-water extractions and the data indicated concentrations of these elements were above that of uncontaminated "background" sediments. Further extraction of U by 8N nitric acid indicated that a significant fraction of the total U is relatively immobile and may be sequestered in mobilization-resistant phases. Fine- and coarse-grained samples in sharp contact with one another were sub-sampled for further scrutiny and identification of U reservoirs. Segregation of the samples into their constituent size fractions coupled with microwave-assisted digestion of bulk samples showed that most of the U contamination was sequestered within the fine-grained fraction. Isotope exchange ( (super 233) U) tests revealed that approximately 51% to 63% of the U is labile, indicating that the remaining fund of U is locked up in mobilization-resistant phases. Analysis by Micro-X-ray Fluorescence and Micro-X-ray Absorption Near-Edge Spectroscopy (mu -XRF and mu -XANES) showed that U is primarily associated with Ca and is predominately U(VI). The spectra obtained on U-enriched "hot spots" using Time-Resolved Laser-Induced Fluorescence Spectroscopy (TRLIFS) provide strong evidence for uranophane-type [Ca(UO (sub 2) ) (sub 2) (SiO (sub 3) OH) (sub 2) (H (sub 2) O) (sub 5) ] and uranyl phosphate [Ca(UO (sub 2) ) (sub 2) (PO (sub 4) ) (sub 2) (H (sub 2) O) (sub 10-12) ] phases. These data show that disseminated micro-precipitates can form in narrow pore spaces within the finer-grained matrix and that these objects are likely not restricted to lithic fragment environments. Uranium mobility may therefore be curtailed by precipitation of uranyl silicate and phosphate phases, with additional possible influence exerted by capillary barriers. Consequently, equilibrium-based desorption models that predict the concentrations and mobility of U in the subsurface matrix at Hanford are unnecessarily conservative.

Particularly in the biodetection arena, a rapid development of new platforms has largely been stimulated by a spectrum of novel nanomaterials with physical properties that offer efficient, sensitive and inexpensive molecular sensing. Recently, DNA-functionalized nano-objects have emerged as a new class of nanomaterials that can be controllably assembled in predesigned structures. Such DNA-based nanoscale structures might provide a new detection paradigm due to their regulated optical, electrical and magnetic responses, chemical heterogeneity and high local biomolecular concentration. The specific biorecognition DNA and its physical-chemical characteristics allows for an exploitation of DNA-functionalized nanomaterials for sensing of nucleic acids, while a broad tunability of DNA interactions permits extending their use for detection of proteins, small molecules and ions. We discuss the progress that was achieved in the last decade in the exploration of new detection methods based on DNA-incorporating nanomaterials as well as their applications to gene delivery. The comparison between various detection platforms, their sensitivity and selectivity, and specific applications are reviewed.

Human apurinic endonuclease 1 (Ape1, Ref-1, APEX, HAP1, AP endo) is a multifunctional protein involved in base excision repair of DNA and a redox-dependent transcriptional co-activator. This study investigated whether there is a direct relationship between Ape1 and radioresistance in glioma cells, employing the human U87 and U251 cell lines. U87 is intrinsically more radioresistant than U251, which is partly attributable to more cycling U251 cells found in G2/M, the most radiosensitive cell stage, while more U87 cells are found in S and G1, the more radioresistant cell stages. But observed radioresistance is also related to Ape1 activity. U87 has higher levels of Ape1 than does U251, as assessed by Western blot and enzyme activity assays (~1.5-2 fold higher in cycling cells, and ~10 fold higher at G2/M). A direct relationship was seen in cells transfected with CMV-Ape1 constructs; there was a dose-dependent relationship between increasing Ape1 overexpression and increasing radioresistance. Conversely, knock down by siRNA or by pharmacological down regulation of Ape1 resulted in decreased radioresistance. The inhibitors lucanthone and CRT004876 were employed, the former a thioxanthene previously under clinical evaluation as a radiosensitizer for brain tumors and the latter a more specific Ape1 inhibitor. These data suggest that Ape1 may be a useful target for modifying radiation tolerance.

AN - 734214264; 19875443 AB - Lignin is a complex polymer derived from the oxidative coupling of three classical monolignols. Lignin precursors are methylated exclusively at the meta-positions (i.e. 3/5-OH) of their phenyl rings by native O-methyltransferases, and are precluded from substitution of the para-hydroxyl (4-OH) position. Ostensibly, the para-hydroxyls of phenolics are critically important for oxidative coupling of phenoxy radicals to form polymers. Therefore, creating a 4-O-methyltransferase to substitute the para-hydroxyl of monolignols might well interfere with the synthesis of lignin. The phylogeny of plant phenolic O-methyltransferases points to the existence of a batch of evolutionarily "plastic" amino acid residues. Following one amino acid at a time path of directed evolution, and using the strategy of structure-based iterative site-saturation mutagenesis, we created a novel monolignol 4-O-methyltransferase from the enzyme responsible for methylating phenylpropenes. We show that two plastic residues in the active site of the parental enzyme are vital in dominating substrate discrimination. Mutations at either one of these separate the evolutionarily tightly linked properties of substrate specificity and regioselective methylation of native O-methyltransferase, thereby conferring the ability for para-methylation of the lignin monomeric precursors, primarily monolignols. Beneficial mutations at both sites have an additive effect. By further optimizing enzyme activity, we generated a triple mutant variant that may structurally constitute a novel phenolic substrate binding pocket, leading to its high binding affinity and catalytic efficiency on monolignols.

The quantitative health objectives (QHOs) established numerical limits for these metrics and the policy statement identified a calculation scheme for estimating the risk metrics based on probabilistic risk assessments (PRAs) carried out at various plants. The original policy statement also included a large release goal but this goal, defined to be a release that could lead to an offsite early fatality, was later dropped from further consideration as the numerical value assigned was found to be in conflict with the value of the QHO for early fatalities. For operating light water reactors (LWRs), surrogate risk metrics were developed for QHO 1 and 2, viz., core damage frequency (CDF) and large early release frequency (LERF), that can be estimated from level 1 and level 2 PRAs without having to go through a site-specific level 3 PRA.

We present here complete genome sequences of two E. coli B strains, REL606, used in a long-term evolution experiment, and BL21(DE3), widely used to express recombinant proteins. The two genomes differ in length by 72,304 bp and have 426 single base pair differences, a seemingly large difference for laboratory strains having a common ancestor within the last 67 years. Transpositions by IS1 and IS150 have occurred in both lineages. Integration of the DE3 prophage in BL21(DE3) apparently displaced a defective prophage in the l attachment site of B. As might have been anticipated from the many genetic and biochemical experiments comparing B and K-12 over the years, the B genomes are similar in size and organization to the genome of E. coli K-12 MG1655 and have >99% sequence identity over ~92% of their genomes. E. coli B and K-12 differ considerably in distribution of IS elements and in location and composition of larger mobile elements. An unexpected difference is the absence of a large cluster of flagella genes in B, due to a 41 kbp IS1-mediated deletion. Gene clusters that specify the LPS core, O antigen, and restriction enzymes differ substantially, presumably because of horizontal transfer. Comparative analysis of 32 independently isolated E. coli and Shigella genomes, both commensals and pathogenic strains, identifies a minimal set of genes in common plus many strain-specific genes that constitute a large E. coli pan-genome.

The recent reduction in the cost of 2nd generation thin-film PV is remarkable, meeting the production milestone of $1 per watt in the fourth quarter of 2008. This achievement holds great promise for the future. However, the questions remaining are whether the expense of PV modules can be lowered further, and if there are resource- and environmental-impact constraints to growth. I examine the potential of thin-films in a prospective life-cycle analysis, focusing on direct costs, resource availability, and environmental impacts. These three aspects are closely related; developing thinner solar cells and recycling spent modules will become increasingly important in resolving cost, resource, and environmental constraints to large scales of sustainable growth.

The current series of studies is a preliminary exploration of the psychometric properties of the SURPS in two populations (undergraduate and high school students). In study 1, an analysis of the internal structure of two versions of the SURPS shows that the abbreviated version best reflects the 4-factor structure. Concurrent, discriminant, and incremental validity of the SURPS is supported by convergent/divergent relationships between the SURPS subscales and other theoretically relevant personality and drug use criterion measures. In Study 2, the factorial structure of the SURPS is confirmed and evidence is provided for its test-retest reliability and validity with respect to measuring personality vulnerability to reinforcement-specific substance use patterns. In Study 3, the SURPS was administered in a more youthful population to test its sensitivity in identifying younger problematic drinkers. The results from the current series of studies demonstrate support for the reliability and construct validity of the SURPS, and suggest that four personality dimensions may be linked to substance-related behavior through different reinforcement processes. This brief assessment tool may have important implications for clinicians and future research.

This paper investigates the effect of mixed Ni-Al hydroxide precipitate formation and aging on Ni solubility and bioavailability in laboratory contaminated soils. Two Delaware agricultural soils were reacted with a 3 mM Ni solution for 12 months at pH's above and below the threshold for mixed Ni-Al hydroxide formation. Ni speciation was determined at 1, 6, and 12 months using X-ray absorption spectroscopy (XAS). Precipitate solubility was examined through desorption experiments using HNO3 and EDTA as desorbing agents, whereas metal bioavailability was assessed using a Ni-specific bacterial biosensor. For both soils, the formation of Ni-Al hydroxide surface precipitates resulted in a reduction in the fraction of desorbed and bioavailable Ni. However, precipitate dissolution was greater, particularly with EDTA, than in published studies on isolated soil clay fractions, and less affected by aging processes. These results suggest that mixed Ni-Al hydroxide phases forming in real world environments may be both longer-lasting and more susceptible to ligand-promoted dissolution than previously expected.

Consequently, plants undergo evapotranspiration that contaminates the ambient air and, thus, undermines the merits of phytoremediation. Under laboratory conditions, endophytic bacteria equipped with the appropriate degradation pathways can improve in planta degradation of volatile organic contaminants. However, several obstacles must be overcome before engineered endophytes will be successful in field-scale phytoremediation projects. Here we report the first in situ inoculation of poplar trees, growing on a TCE-contaminated site, with the TCE-degrading strain Pseudomonas putida W619-TCE. In situ bioaugmentation with strain W619-TCE reduced TCE evapotranspiration by 90% under field conditions. This encouraging result was achieved after the establishment and enrichment of P. putida W619-TCE as a poplar root endophyte and by further horizontal gene transfer of TCE metabolic activity to members of the poplar's endogenous endophytic population. Since P. putida W619-TCE was engineered via horizontal gene transfer, its deliberate release is not restricted under European genetically modified organisms (GMO) regulations.

AN - 733946253; 19846769 AB - Suberin, a polyester polymer in the cell wall of terrestrial plants, controls the transport of water and nutrients and protects plant from pathogenic infections and environmental stresses. Structurally, suberin consists of aliphatic and aromatic domains; p-hydroxycinnamates, such as ferulate, p-coumarate, and/or sinapate, are the major phenolic constituents of the latter. By analyzing the "wall-bound" phenolics of mutant lines of Arabidopsis deficient in a family of acyl-CoA dependent acyltransferase (BAHD) genes, we discovered that the formation of aromatic suberin in Arabidopsis, primarily in seed and root tissues, depends on a member of the BAHD superfamily of enzymes encoded by At5g41040. This enzyme exhibits an omega-hydroxyacid hydroxycinnamoyltransferase activity with an in vitro kinetic preference for feruloyl-CoA and 16-hydroxypalmitic acid. Knocking down or knocking out the At5g41040 gene in Arabidopsis reduces specifically the quantity of ferulate in suberin, but does not affect the accumulation of p-coumarate or sinapate. The loss of the suberin phenolic differentially affects the aliphatic monomer loads and alters the permeability and sensitivity of seeds and roots to salt stress. This highlights the importance of suberin aromatics in the polymer's function.

AN - 734059575; 19780622 AB - Phthalic acid, a ubiquitous organic ligand, formed soluble mono- and biligand complexes with a uranyl ion that was then reduced to a U(IV)-phthalate by a Clostridium species under anaerobic conditions. We confirmed the reduction of the hexavalent uranium to the tetravalent oxidation state by UV-vis absorption and X-ray absorption near edge structure spectroscopy. Sequential micro- and ultrafiltration of the solution revealed that the bioreduced uranium was present as a colloid with particles between 0.03 and 0.45 microm. Analysis with extended X-ray absorption fine structure revealed the association of the reduced uranium with the phthalic acid as a repeating biligand 1:2 U(IV):phthalic acid polymer. This is the first report of the formation of a U(IV) complexed to two phthalic acid molecules in the form of a polymeric colloid. Although it was proposed that the bioreduction and the precipitation of uranium might be an invaluable strategy to immobilize uranium in contaminated environments, our results suggest that the organic ligands present there might hinder the precipitation of the bioreduced uranium under anaerobic conditions and, thereby, enhance its environmental mobility as uranium organic complexes or colloids.

Metal ions of zinc (Zn), copper (Cu), iron (Fe), and calcium (Ca) are elevated in human amyloid plaques and are thought to be involved in neurodegeneration. Transgenic mouse models of AD also exhibit amyloid plaques, but fail to exhibit the high degree of neurodegeneration observed in humans. In this study, we imaged the Zn, Cu, Fe, and Ca ion distribution in the PSAPP transgenic mouse model representing end-stage AD (N = 6) using synchrotron X-ray fluorescence (XRF) microprobe. In order to account for differences in density in the plaques, the relative protein content was imaged with synchrotron Fourier transform infrared microspectroscopy (FTIRM) on the same samples. FTIRM results revealed a 61% increase in protein content in the plaques compared to the surrounding tissue. After normalizing to protein density, we found that the PSAPP plaques contained only a 29% increase in Zn and there was actually less Cu, Fe, and Ca in the plaque compared to the surrounding tissue. Since metal binding to Ab is thought to induce redox chemistry that is toxic to neurons, the reduced metal binding in PSAPP mice is consistent with the lack of neurodegeneration in these animals. These findings were in stark contrast to the high metal ion content observed in human AD plaques, further implicating the role of metal ions in human AD pathology.

The 2.9-Aa resolution structure of the zinc transporter YiiP from Escherichia coli reveals a richly charged dimer interface stabilized by zinc binding. Site-directed fluorescence resonance energy transfer (FRET) measurements and mutation-activity analysis suggest that zinc binding triggers hinge movements of two electrically repulsive cytoplasmic domains pivoting around four salt bridges situated at the juncture of the cytoplasmic and transmembrane domains. These highly conserved salt bridges interlock transmembrane helices at the dimer interface, where they are well positioned to transmit zinc-induced interdomain movements to reorient transmembrane helices, thereby modulating coordination geometry of the active site for zinc transport. The cytoplasmic domain of YiiP is a structural mimic of metal-trafficking proteins and the metal-binding domains of metal-transporting P-type ATPases. The use of this common structural module to regulate metal coordination chemistry may enable a tunable transport activity in response to cytoplasmic metal fluctuations.

AN - 67649180; 19716751 AB - More than 80% of addicted individuals fail to seek treatment, which might reflect impairments in recognition of severity of disorder. Considered by some as intentional deception, such 'denial' might instead reflect dysfunction of brain networks subserving insight and self-awareness. Here we review the scant literature on insight in addiction and integrate this perspective with the role of: (i) the insula in interoception, self-awareness and drug craving; (ii) the anterior cingulate in behavioral monitoring and response selection (relevant to disadvantageous choices in addiction); (iii) the dorsal striatum in automatic habit formation; and (iv) drug-related stimuli that predict emotional behavior in addicted individuals, even without conscious awareness. We discuss implications for clinical treatment including the design of interventions to improve insight into illness severity in addiction.

21125379; 11058994 AB - Salvinorin A (SA) is a potent kappa opioid agonist with a brief duration of action. Consistent with this, our previous positron emission tomography (PET) studies of carbon-11 labeled SA showed that brain levels decrease rapidly after intravenous administration. SA is rapidly metabolized, giving the much less potent salvinorin B (SB), which is presumed to be responsible in part for SA's brief duration of action. To test this, we labeled the metabolically stable methyl ester of SA and SB with carbon-11 and compared their pharmacokinetics by PET imaging after intravenous administration to baboons. Labeling of salvinorin B ethoxymethyl ether (EOM-SB), a derivative with greater potency and resistance to metabolism, provided an additional test of the role of metabolism in brain efflux. Plasma analysis confirmed that SB and EOM-SB exhibited greater metabolic stability than SA. However, the three compounds exhibited very similar pharmacokinetics in brain, entering and exiting rapidly. This suggests that metabolism is not solely responsible for the brief brain residence time of SA. We determined that whole-brain concentrations of EOM- SB declined more slowly than SA after intraperitoneal administration in rodents. This is likely due to a combination in EOM-SB's increased metabolic stability and its decreased plasma protein affinity. Our results suggest that protecting salvinorin A derivatives from metabolism will prolong duration of action, but only when administered by routes giving slow absorption.

In this review, we present the normalized land requirements during the life cycles of conventional- and renewable-energy options, covering coal, natural gas, nuclear, hydroelectric, photovoltaics, wind, and biomass. We compared the land transformation and occupation matrices within a life-cycle framework across those fuel cycles. Although the estimates vary with regional and technological conditions, the photovoltaic (PV) cycle requires the least amount of land among renewable-energy options, while the biomass cycle requires the largest amount. Moreover, we determined that, in most cases, ground-mount PV systems in areas of high insolation transform less land than the coal-fuel cycle coupled with surface mining. In terms of land occupation, the biomass- fuel cycle requires the greatest amount, followed by the nuclear-fuel cycle. Although not detailed in this review, conventional electricity-generation technologies also pose secondary effects on land use, including contamination and disruptions of the ecosystems of adjacent lands, and land disruptions by fuel-cycle- related accidents.

Water containing 7-14 mg L (super -1) PCE was added to the test bed. Perchloroethylene, trichloroethylene, and cis-dichloroethylene were detected in the effluent at an average of 0.12 mg L (super -1) , 3.9 mg L (super -1) , and 1.9 mg L (super -1) , respectively. The total mass of chlorinated ethenes in the water was reduced by 99%. Over 95% of the recovered chlorine was as free chloride in the soil, indicating near-complete dehalogenation of the PCE. Transpiration, volatilization, and accumulation in the trees were all found to be minor loss mechanisms. In contrast, 98% of PCE applied to an unplanted soil chamber was recovered as PCE in the effluent water or volatilized into the air. These results suggest that phytoremediation can be an effective method for treating PCE-contaminated groundwater in field applications. Abstract Copyright (2009) Elsevier, B.V.

The experiment is complicated somewhat as logistics dictated that the column spent significant amounts of time in a sealed state (acting as a batch reactor). Changes accompanying a net reduction in porosity of 4% were quantified including: (1) a 25% net decrease in pores resulting from a 38% loss in the number of pores <10 (super -4) mm (super 3) in volume and a 13% increase in the number of pores of larger size; and (2) a 38% decrease in the number of throats.

AN - 67533092; 18953667 AB - Proteome and transcriptome analysis, combined with mutagenesis, were used to better understand the response of Cupriavidus metallidurans CH34 against lead(II). Structural Pb(II)-resistance genes of the pMOL30-encoded pbrUTRABCD operon formed the major line of defense against Pb(II). However, several general stress response mechanisms under the control of alternative sigma factors such as sigma24/rpoK, sigma32/rpoH and sigma28/fliA were also induced. In addition, the expression of the pbrR(2) cadA pbrC(2) operon of the CMGI-1 region and the chromosomally encoded zntA were clearly induced in the presence of Pb(II), although their respective gene products were not detected via proteomics. After inactivation of the pbrA, pbrB or pbrD genes, the expression of the pbrR(2) cadA pbrC(2) operon went up considerably. This points towards synergistic interactions between pbrUTRABCD and pbrR(2) cadA pbrC(2) to maintain a low intracellular Pb(II) concentration, where pbrR(2) cadA pbrC(2) gene functions can complement and compensate for the mutations in the pbrA and pbrD genes. This role of zntA and cadA to complement for the loss of pbrA was further confirmed by mutation analysis. The pbrB:: colonsTn(Km2) mutation resulted in the most significant decrease of Pb(II) resistance, indicating that Pb(II) sequestration, avoiding re-entry of this toxic metal ion, forms a critical step in the pbr-encoded Pb(II) resistance mechanism.

AN - 67474751; 19590267 AB - Ongoing uncertainties have existed regarding possible effects at low photon energies of two copper filters covering Element 1 of the Harshaw Type-8814 thermoluminescent dosimeter badge casing. To address these, Brookhaven National Laboratory's (BNL) Personnel Monitoring Group conducted a test in which Type-8814 badges with one copper filter covering Element 1 were irradiated at several low-energy levels side-by-side with the same number of badges with two copper filters covering Element 1. A review of exposures to personnel at Brookhaven Laboratory to possible low-energy photon flux was also conducted. From both the test and the review of exposures, it can be concluded that, for radiological work under the conditions at BNL, there is no apparent dosimetric difference if one or two copper filters cover Element 1 of the Type-8814 badge.

The arsenic-induced transcriptome of C. metallidurans CH34 showed that the genes most upregulated in the presence of arsenate were all located within the ars operon, with none of the other numerous heavy metal resistance systems present in CH34 being induced. A transcriptional fusion between the luxCDABE operon and the arsR promoter/operator (P/O) region was used to confirm the in vivo induction of the ars operon by arsenite and arsenate. The arsR gene was cloned into expression vectors allowing for the overexpression of the ArsR protein as either his-tagged or untagged protein. The ability of the purified ArsR proteins to bind to the ars P/O region was analyzed in vitro by gel mobility shift assays. ArsR showed an affinity almost exclusively to its own ars P/O region. Dissociation of ArsR and its P/O region was metal dependent, and based on decreasing degrees of dissociation three groups of heavy metals could be distinguished: As(III), Bi(III), Co(II), Cu(II), Ni(II); Cd(II); Pb(II) and Zn(II), while no dissociation was observed in the presence of As(V).

Its binding profile indicates that [ super(11)C]PR04.MZ may be suited as a PET radioligand for the non-invasive exploration of striatal and extrastriatal DAT populations. As a key feature, its structural design facilitates both, labelling with fluorine-18 at its terminally fluorinated butynyl moiety and carbon-11 at its methyl ester function. The present report concerns the efficient [ super(11)C]MeI mediated synthesis of [ super(11)C]PR04.MZ from an O-desmethyl precursor trifluoroacetic acid salt with Rb sub(2)CO sub(3) in DMF in up to 95 +/- 5% labelling yield. A preliminary mu PET-experiment demonstrates the reversible, highly specific binding of [ super(11)C]PR04.MZ in the brain of a male Sprague-Dawley rat.

Diffraction-enhanced imaging (DEI) uses a monochromatic x-ray beam and a silicon crystal analyzer to produce images in which attenuation contrast is greatly enhanced and x-ray refraction at tissue boundaries can be detected. The aim of this study was to test the efficacy of conventional x-ray tube-based DEI for the detection of soft tissues in experimental samples. Materials and Methods - Cadaveric human tali (normal and degenerated) and a knee and thumb were imaged with DEI using a conventional x-ray tube and DEI setup that included a double-silicon crystal monochromator and a silicon crystal analyzer positioned between the imaged object and the detector. Results - Diffraction-enhanced images of the cadaveric tali allowed the visualization of cartilage and its specific level of degeneration for each specimen. There was a significant correlation between the grade of cartilage integrity as assessed on the tube diffraction-enhanced images and on their respective histologic sections (r = 0.97, P = .01). Images of the intact knee showed the articular cartilage edge of the femoral condyle, even when superimposed by the tibia. In the thumb image, it was possible to visualize articular cartilage, tendons, and other soft tissues. Conclusion - DEI based on a conventional x-ray tube allows the visualization of skeletal and soft tissues simultaneously.

11812712 AB - The NASA Langley Research Center (LaRC) airborne High Spectral Resolution Lidar (HSRL) measures vertical profiles of aerosol extinction, backscatter, and depolarization at both 532 nm and 1064 nm. In March of 2006 the HSRL participated in the Megacity Initiative: Local and Global Research Observations (MILAGRO) campaign along with several other suites of instruments deployed on both aircraft and ground based platforms. This paper presents high spatial and vertical resolution HSRL measurements of aerosol extinction and optical depth from MILAGRO and comparisons of those measurements with similar measurements from other sensors and model predictions. HSRL measurements coincident with airborne in situ aerosol scattering and absorption measurements from two different instrument suites on the C-130 and G-1 aircraft, airborne aerosol optical depth (AOD) and extinction measurements from an airborne tracking sunphotometer on the J-31 aircraft, and AOD from a network of ground based Aerosol Robotic Network (AERONET) sun photometers are presented as a validation of the HSRL aerosol extinction and optical depth products. Regarding the extinction validation, we find bias differences between HSRL and these instruments to be less than 3% (0.01 km super(− 1)) at 532 nm, the wavelength at which the HSRL technique is employed. The rms differences at 532 nm were less than 50% (0.015 km super(− 1)). To our knowledge this is the most comprehensive validation of the HSRL measurement of aerosol extinction and optical depth to date. The observed bias differences in ambient aerosol extinction between HSRL and other measurements is within 15-20% at visible wavelengths, found by previous studies to be the differences observed with current state-of-the-art instrumentation (Schmid et al., 2006).

Using the conserved sequence motifs of BAHD members, we searched the genome sequences of Populus and Arabidopsis, and identified, respectively, 94- and 61-putative genes. Subsequently, we analyzed the phylogeny, gene structure, and chromosomal distribution of BAHD members of both species; then, we profiled expression patterns of BAHD genes by "in silico" northern- and microarray-analyses based on public databases, and by RT-PCR. While our genomic- and bioinformatic- analyses provided full sets of BAHD superfamily genes, and cleaned up a few existing annotation errors, importantly it led to our recognizing several unique Arabidopsis BAHD genes that inversely overlapped with their neighboring genes on the genome, and disclosing a potential natural anti-sense regulation for gene expressions. Systemic gene-expression profiling of BAHD members revealed distinct tissue-specific/preferential expression patterns, indicating their diverse biological functions. Our study affords a strong knowledge base for understanding BAHD members' evolutionary relationships and gene functions implicated in plant growth, development and metabolism.

AN - 67462324; 19543288 AB - Clostridium botulinum neurotoxins (BoNTs) cleave neuronal proteins responsible for neurotransmitter release, causing the neuroparalytic disease botulism. BoNT serotypes B, D, F and G cleave and inactivate vesicle-associated membrane protein (VAMP), each at a unique peptide bond. The specificity of BoNTs depends on the mode of substrate recognition. We have investigated the mechanism of substrate recognition of BoNT F by determining the crystal structures of its complex with two substrate-based inhibitors, VAMP 22-58/Gln58D-cysteine and 27-58/Gln58D-cysteine. The inhibitors bind to BoNT F in the canonical direction (as seen for BoNTs A and E substrates) but are positioned specifically via three major exosites away from the active site. The cysteine sulfur of the inhibitors interacts with the zinc and exists as sulfinic acid in the inhibitor VAMP 27-58/Gln58D-cysteine. Arg133 and Arg171, which form part of two separate exosites, are crucial for substrate binding and catalysis.

However, the biogenicity of these putative microfossils has been called into question, primarily because the sample collection locality is a black, carbon-rich, brecciated chert dike representing an Archean submarine hydrothermal spring, suggesting a formation via an abiotic organic synthesis mechanism. Here we describe the macromolecular hydrocarbon structure, carbon bonding, functional group chemistry, and biotic element abundance of carbonaceous matter associated with these filamentous features. These characteristics are similar to those of biogenic kerogen from the ca. 1.9 Ga old Gunflint Formation. Although an abiotic origin cannot be entirely ruled out, it is unlikely that known abiotic synthesis mechanisms could recreate both the structural and compositional complexity of this ancient carbonaceous matter. Thus, we find that a biogenic origin for this material is more likely, implying that the Apex microbe-like features represent authentic biogenic organic matter.

Diffraction enhanced imaging (DEI), a phase contrast x- ray imaging technique, has greater soft tissue contrast than conventional radiography and generates higher resolution images than magnetic resonance microimaging. Thus, in this proof of principle study, DEI in micro-CT mode was performed on the brains of AD-model mice to determine if DEI can visualize A beta plaques. Results revealed small nodules in the cortex and hippocampus of the brain. Histology confirmed that the features seen in the DEI images of the brain were A beta plaques. Several anatomical structures, including hippocampal subregions and white matter tracks, were also observed. Thus, DEI has strong promise in early diagnosis of AD, as well as general studies of the mouse brain.

Infrared radiation was used to obtain Fourier transform infrared (FTIR) spectra from which water concentrations were calculated, and to map variations in water concentrations across zones of spherulites and glass from the approximately 23 million year old Sycamore Canyon lava flow of southern Arizona. Lighter-colored, thicker flow bands consist of gray glass, fine-grained quartz, and large (1.0 to 1.5 mm) spherulites. Darker-colored, thinner flow bands consist of orange glass and smaller (0.1 to 0.2 mm) spherulites. The centers of both large and small spherulites are occupied by either (1) a quartz or sanidine crystal, (2) a granophyric intergrowth, or (3) a vesicle. Mapping of water concentration (dominantly OH (super -) in glass and OH (super -) and H (sub 2) O in sanidine crystals) illustrates fluctuating water availability during quenching of the host melt. Textures of large spherulites in the lighter (gray) bands in some cases indicate complex quenching histories that suggest that local water concentration controlled the generation of glass versus crystals. Small spherulites in darker (orange) bands have only one generation of radiating crystal growth. Both the glass surrounding spherulites, and the crystals in the spherulites contain more water in the gray flow bands than in the orange flow bands. Flow banding in the Sycamore Canyon lava flow may have originated by the stretching of a magma that contained pre-existing zones (vesicles or proto-vesicles) of contrasting water concentration, as the magma flowed in the conduit and on the surface. Variation in the original water concentration in the alternating layers is interpreted to have resulted in differences in undercooling textures in spherulites in the lighter compared to the darker flow bands.

AN - 67361110; 19478067 AB - Anterior cingulate cortex (ACC) hypoactivations during cognitive processing characterize drug addicted individuals as compared with healthy controls. However, impaired behavioral performance or task disengagement may be crucial factors. We hypothesized that ACC hypoactivations would be documented in groups matched for performance on an emotionally salient task. Seventeen individuals with current cocaine use disorders (CUD) and 17 demographically matched healthy controls underwent functional magnetic resonance imaging during performance of a rewarded drug cue-reactivity task previously shown to engage the ACC. Despite lack of group differences in objective or subjective task-related performance, CUD showed more ACC hypoactivations throughout this emotionally salient task. Nevertheless, intensity of emotional salience contributed to results: (i) CUD with the largest rostroventral ACC [Brodmann Area (BA) 10, 11, implicated in default brain function] hypoactivations to the most salient task condition (drug words during the highest available monetary reward), had the least task-induced cocaine craving; (ii) CUD with the largest caudal-dorsal ACC (BA 32) hypoactivations especially to the least salient task condition (neutral words with no reward) had the most frequent current cocaine use; and (iii) responses to the most salient task condition in both these ACC major subdivisions were positively intercorrelated in the controls only. In conclusion, ACC hypoactivations in drug users cannot be attributed to task difficulty or disengagement. Nevertheless, emotional salience modulates ACC responses in proportion to drug use severity. Interventions to strengthen ACC reactivity or interconnectivity may be beneficial in enhancing top-down monitoring and emotion regulation as a strategy to reduce impulsive and compulsive behavior in addiction.

We propose a conceptual explanation of this finding and illustrate it using a simple model in which metabolic and regulatory networks of prokaryotes are shaped by horizontal gene transfer of coregulated metabolic pathways. Adapting to a new environmental condition monitored by a new transcription factor (e.g., learning to use another nutrient) involves both acquiring new enzymes and reusing some of the enzymes already encoded in the genome. As the repertoire of enzymes of an organism (its toolbox) grows larger, it can reuse its enzyme tools more often and thus needs to get fewer new ones to master each new task. From this observation, it logically follows that the number of functional tasks and their regulators increases faster than linearly with the total number of genes encoding enzymes. Genomes can also shrink, e.g., because of a loss of a nutrient from the environment, followed by deletion of its regulator and all enzymes that become redundant. We propose several simple models of network evolution elaborating on this toolbox argument and reproducing the empirically observed quadratic scaling. The distribution of lengths of pathway branches in our model agrees with that of the real-life metabolic network of Escherichia coli. Thus, our model provides a qualitative explanation for broad distributions of regulon sizes in prokaryotes.

These fibers mediate adhesion to various surfaces, including host cells, and play crucial roles in pathogenesis. Pili are polymers composed of thousands of individual subunit proteins. Understanding how these subunit proteins cross the bacterial envelope and correctly assemble at the cell surface is important not only for basic biology but also for the development of novel antimicrobial agents. The chaperone/usher pilus biogenesis pathway is one of the best-understood protein secretion systems, thanks largely to innovative efforts in biophysical techniques such as X-ray crystallography and cryo-electron microscopy. Such a combined approach holds promise for further elucidating remaining questions regarding the multi-step and highly dynamic pilus assembly process, as well as for studying other protein secretion and organelle biogenesis systems.

No phase transition has been observed within the pressure range investigated. Axial and volume isothermal Equations of State (EoS) of vanadinite were determined. Fitting the P-V data with a third-order Birch-Murnaghan (BM) EoS, using the data weighted by the uncertainties in P and V, we obtained: V 0 = 681(1) Aa3, K 0 = 41(5) GPa, and K' = 12.5(2.5). The evolution of the lattice constants with P shows a strong anisotropic compression pattern. The axial bulk moduli were calculated with a third-order "linearized" BM-EoS. The EoS parameters are: a 0 = 10.3302(2) Aa, K 0(a) = 35(2) GPa and K'(a) = 10(1) for the a-axis; c 0 = 7.3520(3) Aa, K 0(c) = 98(4) GPa, and K'(c) = 9(2) for the c-axis (K 0(a):K 0(c) = 1:2.80). Axial and volume Eulerian-finite strain (fe) at different normalized stress (Fe) were calculated. The weighted linear regression through the data points yields the following intercept values: Fe a (0) = 35(2) GPa for the a-axis, Fe c (0) = 98(4) GPa for the c-axis and Fe V (0) = 45(2) GPa for the unit-cell volume. The slope of the regression lines gives rise to K' values of 10(1) for the a-axis, 9(2) for the c-axis and 11(1) for the unit cell-volume. A comparison between the HP-elastic response of vanadinite and the iso-structural apatite is carried out. The possible reasons of the elastic anisotropy are discussed.

For example, the aircraft flew too fast and its altitude was too high. Part 2 (this paper) then focuses on the examination of several possible improvements on the mobile cloud tomography method by means of observation system simulation experiment. We find that the incorporation of the L sub(1) norm total variation regularization in the tomographic retrieval algorithm better reproduces small scale discontinuous structure than the widely used L sub(2) norm Tikhonov regularization and successfully resolves sharp cloud edges. The simulation experiments reveal that a typical ground-based mobile cloud tomography setup substantially outperforms an airborne one because of its slower moving speed and greater contrast in microwave brightness between clouds and the cosmic background. The simulations show that, as expected, the retrieval error increases monotonically with radiometer noise level and the uncertainty in background brightness temperature. It is also revealed that a slower platform or a faster scanning radiometer results in more scan cycles and better overlapping between the swaths of successive scan cycles, both of which are highly favorable for cloud tomography retrieval. The last factor examined is aircraft height. It is shown that the best retrieval is obtained when the aircraft data are collected at the altitudes between 500 m to 1000 m above the cloud top. To summarize, this research demonstrates the feasibility of tomographically retrieving cloud structure using current scanning microwave radiometer technology and provides several general guidelines by which to improve future field-based studies of cloud tomography.

AN - 67232872; 19439595 AB - Positron emission tomography studies in drug-addicted patients have shown that exposure to drug-related cues increases striatal dopamine, which displaces binding of the D(2) ligand, [(11)C]-raclopride. However, it is not known if animals will also show cue-induced displacement of [(11)C]-raclopride binding. In this study, we use [(11)C]-raclopride imaging in awake rodents to capture cue-induced changes in dopamine release associated with the conditioned place preference model of drug craving. Ten animals were conditioned to receive cocaine in a contextually distinct environment from where they received saline. Following conditioning, each animal was tested for preference and then received two separate [(11)C]-raclopride scans. For each scan, animals were confined to the cocaine and/or the saline-paired environment for the first 25 min of uptake, after which they were anesthetized and scanned. [(11)C]-raclopride uptake in the saline-paired environment served as a within-animal control for uptake in the cocaine-paired environment. Cocaine produced a significant place preference (p = 0.004) and exposure to the cocaine-paired environment decreased [(11)C]-raclopride binding relative to the saline-paired environment in both the dorsal (20%; p < 0.002) and ventral striatum (22%; p < 0.05). The change in [(11)C]-raclopride binding correlated with preference in the ventral striatum (R(2) = -0.87; p = 0.003). In this region, animals who showed little or no preference exhibited little or no change in [(11)C]-raclopride binding in the cocaine-paired environment. This noninvasive procedure of monitoring neurochemical events in freely moving, behaving animals advances preclinical molecular imaging by interrogating the degree to which animal models reflect the human condition on multiple dimensions, both biological and behavioral.

Secondary precipitates of U(VI) silicate precipitates (boltwoodite and uranophane) were present dominantly in shallow-depth sediments (15-16 m bgs), while adsorbed U(VI) phases and polynuclear U(VI) surface precipitates were considered to dominate in intermediate-depth sediments (20-25 m bgs). Only natural uranium was observed in the deeper sediments (>28 m bgs) with no signs of contact with tank wastes containing Hanford-derived U(VI). Across all depths, most of the U(VI) was preferentially associated with the silt and clay size fractions of sediments. Strong correlation between U(VI) and Ca was found in the shallow-depth sediments, especially for the precipitated U(VI) silicates. Because U(VI) silicate precipitates dominate in the shallow-depth sediments, the released U(VI) concentration by macroscopic (bi)carbonate leaching resulted from both desorption and dissolution processes. Having different U(VI) surface phases in the Hanford contaminated sediments indicates that the U(VI) release mechanism could be complicated and that detailed characterization of the sediments using several different methods would be needed to estimate U(VI) fate and transport correctly in the vadose zone.

AN - 67218045; 19420266 AB - When exposed to drug conditioned cues (stimuli associated with the drug), addicted individuals experience an intense desire for the drug, which is associated with increased dopamine cell firing. We hypothesized that drug-related words can trigger activation in the mesencephalon, where dopaminergic cells are located. During functional magnetic resonance imaging (fMRI), 15 individuals with cocaine use disorders and 15 demographically matched healthy control subjects pressed buttons for color of drug-related versus neutral words. Results showed that the drug words, but not neutral words, activated the mesencephalon in the cocaine users only. Further, in the cocaine users only, these increased drug-related mesencephalic responses were associated with enhanced verbal fluency specifically for drug words. Our results for the first time demonstrate fMRI response to drug words in cocaine-addicted individuals in mesencephalic regions as possibly associated with dopaminergic mechanisms and with conditioning to language (in this case drug words). The correlation between the brief verbal fluency test, which can be easily administered (crucial for clinical studies), and fMRI cue reactivity could be used as a biomarker of neurobiological changes in addiction.

We recently reported that one night of sleep deprivation increased dopamine in striatum (measured with [ super(11)C]raclopride, a PET radiotracer that competes with endogenous dopamine for binding to D2 receptors) and that these increases were associated with impaired performance in a visual attention task. To better understand this association here we evaluate the relationship between changes in striatal dopamine (measured as changes in D2 receptor availability using PET and [ super(11)C]raclopride) and changes in brain activation to a visual attention task (measured with BOLD and fMRI) when performed during sleep deprivation versus during rested wakefulness. We find that sleep induced changes in striatal dopamine were associated with changes in cortical brain regions modulated by dopamine (attenuated deactivation of anterior cingulate gyrus and insula) but also in regions that are not recognized targets of dopaminergic modulation (attenuated activation of inferior occipital cortex and cerebellum). Moreover, the increases in striatal dopamine as well as its associated regional activation and deactivation patterns correlated negatively with performance accuracy. These findings therefore suggest that hyperstimulation of D2 receptors in striatum may contribute to the impairment in visual attention during sleep deprivation. Thus, while dopamine increases in prefrontal regions (including stimulation of D1 receptors) may facilitate attention our findings suggest that hyperstimulation of D2 receptors in striatum may impair it. Alternatively, these associations may reflect a compensatory striatal dopamine response (to maintain arousal) that is superimposed on a larger response to sleep deprivation.

Procedures Freely moving adult male rats were given SA intraperitoneally during uptake and trapping of the brain metabolic radiotracer, 2-deoxy-2-[F-18]fluoro-d-glucose (FDG), followed by image acquisition in a dedicated animal positron emission tomography (PET) system. Age-matched control animals received vehicle treatment. Animal behavior during FDG uptake was recorded digitally and later analyzed for locomotion. Group differences in regional FDG uptake normalized to whole brain were determined using Statistical Parametric Mapping (SPM) and verified by region of interest (ROI) analysis. Results SA-treated animals demonstrated significant increases in FDG uptake compared to controls in several brain regions associated with the distribution of KOR such as the periaqueductal grey, bed nucleus of the stria terminalis and the cerebellar vermis, as well as in the hypothalamus. Significant bilateral activations were also observed in the auditory, sensory, and frontal cortices. Regional decreases in metabolic demand were observed bilaterally in the dorsolateral striatum and hippocampus. Locomotor activity did not differ between SA and vehicle during FDG uptake. Conclusions We have provided the first extensive maps of cerebral metabolic activation due to the potent Kappa -opioid agonist, salvinorin A. A major finding from our small animal PET studies using FDG was that neural circuits affected by SA may not be limited to direct activation or inhibition of kappa-receptor-expressing cells. Instead, salvinorin A may trigger brain circuits that mediate the effects of the drug on cognition, mood, fear and anxiety, and motor output.

For each formulation the dominant source of Aitken mode particles is NPF with only a minor contribution from primary emissions, whereas for the accumulation mode both emissions and transfer of particles from the Aitken mode are important. The dominant sink of Aitken mode number is coagulation, whereas the dominant sink of accumulation mode number is wet deposition (including cloud processing), with a minor contribution from coagulation. The aerosol mass concentration, which is primarily in the accumulation mode, is relatively insensitive to NPF formulation despite order-of-magnitude differences in the Aitken mode number concentration among the different parameterizations. The dominant sensitivity of accumulation mode number concentration is to the number of emitted particles (for constant mass emission rate). Comparison of modeled aerosol properties with aircraft measurements shows, as expected, better agreement in aerosol mass concentration than in aerosol number concentration for all NPF formulations considered. These comparisons yield instances of rather accurate simulations in the planetary boundary layer, with poor model performance in the free troposphere attributed mainly to lack of representation of biomass burning and/or to long-range transport of particles from outside the model domain. Agreement between model results and measurements is improved by using smaller grid cells (12 km versus 60 km). JF - Journal of Geophysical Research.

AN - 67128030; 19265437 AB - The flavoenzyme nitroalkane oxidase is a member of the acyl-CoA dehydrogenase superfamily. Nitroalkane oxidase catalyzes the oxidation of neutral nitroalkanes to nitrite and the corresponding aldehydes or ketones. Crystal structures to 2.2 A resolution or better of enzyme complexes with bound substrates and of a trapped substrate-flavin adduct are described. The D402N enzyme has no detectable activity with neutral nitroalkanes [Valley, M. P., and Fitzpatrick, P. F. (2003) J. Am. Chem. Soc. 125, 8738-8739]. The structure of the D402N enzyme crystallized in the presence of 1-nitrohexane or 1-nitrooctane shows the presence of the substrate in the binding site. The aliphatic chain of the substrate extends into a tunnel leading to the enzyme surface. The oxygens of the substrate nitro group interact both with amino acid residues and with the 2'-hydroxyl of the FAD. When nitroalkane oxidase oxidizes nitroalkanes in the presence of cyanide, an electrophilic flavin imine intermediate can be trapped [Valley, M. P., Tichy, S. E., and Fitzpatrick, P. F. (2005) J. Am. Chem. Soc. 127, 2062-2066]. The structure of the enzyme trapped with cyanide during oxidation of 1-nitrohexane shows the presence of the modified flavin. A continuous hydrogen bond network connects the nitrogen of the CN-hexyl-FAD through the FAD 2'-hydroxyl to a chain of water molecules extending to the protein surface. Together, our complementary approaches provide strong evidence that the flavin cofactor is in the appropriate oxidation state and correlates well with the putative intermediate state observed within each of the crystal structures.

These metals are used selectively in the manufacture of solar cells, and emission and energy factors in their production are used in the life cycle analysis (LCA) of photovoltaics. Significant changes have occurred in the production and associated emissions for these metals over the last 10 years, which are not described in the LCA databases. Furthermore, emission and energy factors for several of the by-products of the base metal production were lacking. This review article aims in updating the life cycle inventories associated with the production of the base metals (Zn, Cu), and defining the production paths and emission and energy allocations for the minor metals (Cd, Ge, In, Mo, Se, and Te) used in photovoltaics.

AN - 67039084; 18496524 AB - Individuals with current cocaine use disorders (CUD) form a heterogeneous group, making sensitive neuropsychological (NP) comparisons with healthy individuals difficult. The current study examined the effects on NP functioning of four factors that commonly vary among CUD: urine status for cocaine (positive vs negative on study day), cigarette smoking, alcohol consumption, and dysphoria. Sixty-four cocaine abusers were matched to healthy comparison subjects on gender and race; the groups also did not differ in measures of general intellectual functioning. All subjects were administered an extensive NP battery measuring attention, executive function, memory, facial and emotion recognition, and motor function. Compared with healthy control subjects, CUD exhibited performance deficits on tasks of attention, executive function, and verbal memory (within one standard deviation of controls). Although CUD with positive urine status, who had higher frequency and more recent cocaine use, reported greater symptoms of dysphoria, these cognitive deficits were most pronounced in the CUD with negative urine status. Cigarette smoking, frequency of alcohol consumption, and dysphoria did not alter these results. The current findings replicate a previously reported statistically significant, but relatively mild NP impairment in CUD as compared with matched healthy control individuals and further suggest that frequent/recent cocaine use [corrected] may mask underlying cognitive (but not mood) disturbances. These results call for development of pharmacological agents targeted to enhance cognition, without negatively impacting mood in individuals addicted to cocaine.

AN - 66987520; 19201512 AB - Globally carbon nanoparticles are increasingly utilized, yet it is not known if these nanoparticles pose a threat to the environment or human health. This investigation examined 'as-prepared', and acid cleaned carbon nanoparticle physicochemical characteristics (by FTIR, TEM, FESEM, UV-VIS and X-ray microanalysis), and whether these characteristics changed following 2.5-7yr exposure to pH neutral saline or fresh water. To determine if these aqueous aged nanotubes were cytotoxic, these nanotubes were incubated with human epithelial monolayers and analyzed for cell viability (vital staining) and ultrastructural nanoparticle binding/localization (TEM, FESEM). The presence of Ni and Y catalyst, was less damaging to cells than CNT lattice surface oxidation. Extended fresh water storage of oxidized CNTs did not reduce surface reactive groups, nor lessen cell membrane destruction or cell death. However storing oxidized CNTs in saline or NOM significantly reduced CNT-induced cell membrane damage and increased cell survival to control levels.

Here, we evaluate the utility of 6-([ super(18)F]fluoroacetamido)-l-hexanoicanilide ([ super(18)F]FAHA) for positron emission tomography imaging of HDAC activity in the baboon brain. For this purpose, we assessed its in vivo biodistribution, sensitivity to HDAC inhibition, metabolic stability and the distribution of the putative metabolite [ super(18)F]fluoroacetate ([ super(18)F]FAC). Methods: [ super(18)F]FAHA and its metabolite [ super(18)F]FAC were prepared, and their in vivo biodistribution and pharmacokinetics were determined in baboons. [ super(18)F]FAHA metabolism and its sensitivity to HDAC inhibition using suberanilohydroxamic acid (SAHA) were assessed in arterial plasma and by in vitro incubation studies. The chemical form of F-18 in rodent brain was assessed by ex vivo studies. Distribution volumes for [ super(18)F]FAHA in the brain were derived. Results: [ super(18)F]FAHA was rapidly metabolized to [ super(18)F]FAC, and both labeled compounds entered the brain. [ super(18)F]FAHA exhibited regional differences in brain uptake and kinetics. In contrast, [ super(18)F]FAC showed little variation in regional brain uptake and kinetics. A kinetic analysis that takes into account the uptake of peripherally produced [ super(18)F]FAC indicated that SAHA inhibited binding of [ super(18)F]FAHA in the baboon brain dose-dependently. In vitro studies demonstrated SAHA-sensitive metabolism of [ super(18)F]FAHA to [ super(18)F]FAC within the cell and diffusion of [ super(18)F]FAC out of the cell. All radioactivity in brain homogenate from rodents was [ super(18)F]FAC at 7 min postinjection of [ super(18)F]FAHA. Conclusion: The rapid metabolism of [ super(18)F]FAHA to [ super(18)F]FAC in the periphery complicates the quantitative analysis of HDAC in the brain. However, dose-dependent blocking studies with SAHA and kinetic modeling indicated that a specific interaction of [ super(18)F]FAHA in the brain was observed. Validating the nature of this interaction as HDAC specific will require additional studies. Published by Elsevier Inc.

Since the emission inventories and dilution will directly affect predictions of total organic matter and consequently total particulate matter, our objective is to assess the uncertainties in predicted POA before testing and evaluating the performance of secondary organic aerosol (SOA) treatments. Carbon monoxide (CO) is well simulated on most days both over the city and downwind, indicating that transport and mixing processes were usually consistent with the meteorological conditions observed during MILAGRO. Predicted and observed elemental carbon (EC) in the city was similar, but larger errors occurred at remote locations since the overall CO/EC emission ratios in the national emission inventory were lower than in the metropolitan emission inventory. Components of organic aerosols derived from Positive Matrix Factorization of data from several Aerodyne Aerosol Mass Spectrometer instruments deployed both at ground sites and on research aircraft are used to evaluate the model. Modeled POA was consistently lower than the measured organic matter at the ground sites, which is consistent with the expectation that SOA should be a large fraction of the total organic matter mass. A much better agreement was found when modeled POA was compared with the sum of measured QUOTATION_MARKprimary anthropogenicQUOTATION_MARK and QUOTATION_MARKbiomass burningQUOTATION_MARK components on most days, suggesting that the overall magnitude of primary organic particulates released was reasonable. The modeled POA was greater than the total observed organic matter when the aircraft flew directly downwind of large fires, suggesting that biomass burning emission estimates from some large fires may be too high. Predicted total observed organic carbon (TOOC) was also analyzed to assess how emission inventory estimates of volatile organic compounds may impact predictions of SOA.

AN - 66873292; 19118561 AB - Clostridium botulinum produces seven antigenically distinct neurotoxins [C. botulinum neurotoxins (BoNTs) A-G] sharing a significant sequence homology. Based on sequence and functional similarity, it was believed that their three-dimensional structures will also be similar. Indeed, the crystal structures of BoNTs A and B exhibit similar fold and domain association where the translocation domain is flanked on either side by binding and catalytic domains. Here, we report the crystal structure of BoNT E holotoxin and show that the domain association is different and unique, although the individual domains are similar to those of BoNTs A and B. In BoNT E, both the binding domain and the catalytic domain are on the same side of the translocation domain, and all three have mutual interfaces. This unique association may have an effect on the rate of translocation, with the molecule strategically positioned in the vesicle for quick entry into cytosol. Botulism, the disease caused by BoNT E, sets in faster than any other serotype because of its speedy internalization and translocation, and the present structure offers a credible explanation. We propose that the translocation domain in other BoNTs follows a two-step process to attain translocation-competent conformation as in BoNT E. We also suggest that this translocation-competent conformation in BoNT E is a probable reason for its faster toxic rate compared to BoNT A. However, this needs further experimental elucidation.

AN - 66742491; 19016239 AB - Preventing relapse poses a significant challenge to the successful management of methamphetamine (METH) dependence. Although no effective medication currently exists for its treatment, racemic gamma vinyl-GABA (R,S-GVG, vigabatrin) shows enormous potential as it blocks both the neurochemical and behavioral effects of a variety of drugs, including METH, heroin, morphine, ethanol, nicotine, and cocaine. Using the reinstatement of a conditioned place preference (CPP) as an animal model of relapse, the present study specifically investigated the ability of an acute dose of R,S-GVG to block METH-triggered reinstatement of a METH-induced CPP. Animals acquired a METH CPP following a 20-day-period of conditioning, in which they received 10 pairings of alternating METH and saline injections. During conditioning, rats were assigned to one of four METH dosage groups: 1.0, 2.5, 5.0, or 10.0 mg/kg (i.p., n = 8/group). Animals in all dosage groups demonstrated a robust and consistent CPP. This CPP was subsequently extinguished in each dosage group with repeated saline administration. Upon extinction, all groups reinstated following an acute METH challenge. On the following day, an acute dose of R,S-GVG (300 mg/kg, i.p.) was administered 2.5 h prior to an identical METH challenge. R,S-GVG blocked METH-triggered reinstatement in all four groups. Given that drug re-exposure may potentiate relapse to drug-seeking behavior, the ability of R,S-GVG to block METH-triggered reinstatement offers further support for its use in the successful management of METH dependence.

12510583 AB - The association of endophytic bacteria with their plant hosts has a beneficial effect for many different plant species. Our goal is to identify endophytic bacteria that improve the biomass production and the carbon sequestration potential of poplar trees (Populus spp.) when grown in marginal soil and to gain an insight in the mechanisms underlying plant growth promotion. Members of the Gammaproteobacteria dominated a collection of 78 bacterial endophytes isolated from poplar and willow trees. As representatives for the dominant genera of endophytic gammaproteobacteria, we selected Enterobacter sp. strain 638, Stenotrophomonas maltophilia R551-3, Pseudomonas putida W619, and Serratia proteamaculans 568 for genome sequencing and analysis of their plant growth-promoting effects, including root development. Derivatives of these endophytes, labeled with gfp, were also used to study the colonization of their poplar hosts. In greenhouse studies, poplar cuttings (Populus deltoides x Populus nigra DN-34) inoculated with Enterobacter sp. strain 638 repeatedly showed the highest increase in biomass production compared to cuttings of noninoculated control plants. Sequence data combined with the analysis of their metabolic properties resulted in the identification of many putative mechanisms, including carbon source utilization, that help these endophytes to thrive within a plant environment and to potentially affect the growth and development of their plant hosts. Understanding the interactions between endophytic bacteria and their host plants should ultimately result in the design of strategies for improved poplar biomass production on marginal soils as a feedstock for biofuels.

A vertical release pure CO2 fumigation system was superimposed on an existing prediluted CO2 fumigation system and operated on alternate days. The FACE system using prediluted CO2 fumigation technology exhibited less temporal and spatial variability than the pure CO2 fumigation system. The pure CO2 fumigation system tended to over-fumigate the upwind portions of the plot and used 25% more CO2 than the prediluted CO2 fumigation system. The increased CO2 use by the pure CO2 system was exacerbated at low wind speeds. It is not clear if this phenomenon will also be observed in plots with smaller diameters and low-stature vegetation.

However, recent drastic cost reductions in the production of photovoltaics (PV) pave the way for enabling this technology to become cost competitive with fossil fuel energy generation. We show that with the right incentives, cost competitiveness with grid prices in the US (e.g., 6-10 US[cents]/kWh) can be attained by 2020. The intermittency problem is solved by integrating PV with compressed air energy storage (CAES) and by extending the thermal storage capability in concentrated solar power (CSP). We used hourly load data for the entire US and 45-year solar irradiation data from the southwest region of the US, to simulate the CAES storage requirements, under worst weather conditions. Based on expected improvements of established, commercially available PV, CSP, and CAES technologies, we show that solar energy has the technical, geographical, and economic potential to supply 69% of the total electricity needs and 35% of the total (electricity and fuel) energy needs of the US by 2050. When we extend our scenario to 2100, solar energy supplies over 90%, and together with other renewables, 100% of the total US energy demand with a corresponding 92% reduction in energy-related carbon dioxide emissions compared to the 2005 levels.

A major obstacle to studying natural hydrate systems has been the absence of a sophisticated mimic apparatus in which the hydrate formation phenomenon can be reproduced with precision. We have designed and constructed a bench-top unit, namely flexible integrated study of hydrates (FISH), for this purpose. The unit is fully instrumented to precisely record temperatures, pressures and changes in gas volume during absorption/evolution. The Labview software allows rapid and continuous data collection during the hydrate formation/dissociation cycle. In our integrated approach, several host sediments collected from Blake Ridge, a well-researched hydrate site, were characterized using the computed microtomography technique at Beamline X-26A of the National Synchrotron Light Source at Brookhaven National Laboratory. The characterized depleted sediments were then used to study the hydrate formation/decomposition kinetics under various pressures in the FISH unit. We report two hydrate formation methods: one under continuous methane gas-flow conditions (dynamic mode) and the other in which hydrates are formed from the dissolved gas phase by diffusion (static mode). Also reported is a depressurization method, namely the step-down pressure method, to yield gas evolution data. Data from such runs with host sediment from the deepest site (667 metres) is presented. During hydrate formation, the data reveals a temperature signature that is consistent with an exothermic hydrate formation event. In the decomposition cycle, data at various pressures was analysed to yield curves with similar slopes, suggesting a zero-order dependence.

Larger numbers of AS transgenics have to be screened to achieve a targeted level of suppression compared to RNAi. We hypothesized combining AS with RNAi might result in enhanced gene suppression compared to either method individually. AS and HP-RNAi were combined as hairpin antisense (HPAS) constructs containing ~125 bp sense and antisense portions of an untranslated region of the target gene separated by an intron containing an antisense copy of a portion of the target coding region. The 12-desaturase FAD2, the w3-desaturase FAD3 and b-ketoacyl-ACP synthase (KAS) II were targeted in Arabidopsis to evaluate changes in oil composition with AS, HP and HPAS constructs driven by the phaseolin promoter. Modest but statistically significant enhancements in oilseed phenotypes were observed with HPAS relative to AS and HP-RNAi. Phenotypes for HPAS suppression of FAD2 and FAD3 were indistinguishable from their strongest mutant alleles. Our data suggest that HPAS may be useful for: (1) achieving levels of suppression comparable to those of gene knockouts in a tissue specific manner. (2) Maximizing suppression of suboptimal RNAi constructs and (3) minimizing the screening of transgenics to achieve desired oilseed composition.

To rapidly characterize phenolic OMT activities, we adapted Gibbs' reagent, the dye originally used for detecting phenols, to develop a convenient assay method for measuring the catalytic properties of enzymatic transmethylation of phenolics. We demonstrated that Gibbs' reagent reacted with phenolics yielding distinct absorptive characters that we used to further develop the assay to monitor the reactivities of phenolic OMTs. To validate the method, we identified two caffeate/5-hydroxyferulate 3/5-O-methyltransferases (COMTs) from the black cottonwood, Populus trichocarpa. Together with a few other plant type I OMTs, we demonstrated that our Gibbs' reagent-mediated colorimetric assay could reliably determine the functions and kinetic parameters of phenolic OMTs. Because Gibbs' reagent reacting with different regioselectively modified phenolics displays different colorimetric properties, the assay method can be used to monitor both substrate specificity and the regioselectivity of phenolic OMTs.

AN - 66715164; 19554734 AB - A novel single-walled carbon nanotube (SWNT)-based tumor-targeted drug delivery system (DDS) has been developed, which consists of a functionalized SWNT linked to tumor-targeting modules as well as prodrug modules. There are three key features of this nanoscale DDS: (a) use of functionalized SWNTs as a biocompatible platform for the delivery of therapeutic drugs or diagnostics, (b) conjugation of prodrug modules of an anticancer agent (taxoid with a cleavable linker) that is activated to its cytotoxic form inside the tumor cells upon internalization and in situ drug release, and (c) attachment of tumor-recognition modules (biotin and a spacer) to the nanotube surface. To prove the efficacy of this DDS, three fluorescent and fluorogenic molecular probes were designed, synthesized, characterized, and subjected to the analysis of the receptor-mediated endocytosis and drug release inside the cancer cells (L1210FR leukemia cell line) by means of confocal fluorescence microscopy. The specificity and cytotoxicity of the conjugate have also been assessed and compared with L1210 and human noncancerous cell lines. Then, it has unambiguously been proven that this tumor-targeting DDS works exactly as designed and shows high potency toward specific cancer cell lines, thereby forming a solid foundation for further development.

Last updated - 2017-02-22 ER - TY - JOUR T1 - Fast uptake and long-lasting binding of methamphetamine in the human brain: comparison with cocaine. AN - 69756421; 18708148 AB - Methamphetamine is one of the most addictive and neurotoxic drugs of abuse. It produces large elevations in extracellular dopamine in the striatum through vesicular release and inhibition of the dopamine transporter. In the U.S. abuse prevalence varies by ethnicity with very low abuse among African Americans relative to Caucasians, differentiating it from cocaine where abuse rates are similar for the two groups. Here we report the first comparison of methamphetamine and cocaine pharmacokinetics in brain between Caucasians and African Americans along with the measurement of dopamine transporter availability in striatum. Methamphetamine's uptake in brain was fast (peak uptake at 9 min) with accumulation in cortical and subcortical brain regions and in white matter. Its clearance from brain was slow (except for white matter which did not clear over the 90 min) and there was no difference in pharmacokinetics between Caucasians and African Americans. In contrast cocaine's brain uptake and clearance were both fast, distribution was predominantly in striatum and uptake was higher in African Americans. Among individuals, those with the highest striatal (but not cerebellar) methamphetamine accumulation also had the highest dopamine transporter availability suggesting a relationship between METH exposure and DAT availability. Methamphetamine's fast brain uptake is consistent with its highly reinforcing effects, its slow clearance with its long-lasting behavioral effects and its widespread distribution with its neurotoxic effects that affect not only striatal but also cortical and white matter regions. The absence of significant differences between Caucasians and African Americans suggests that variables other than methamphetamine pharmacokinetics and bioavailability account for the lower abuse prevalence in African Americans.

It is shown that inadequate representation of relative dispersion in climate models leads to an overestimation of cloud albedo, resulting in a negative bias of global mean shortwave cloud radiative forcing that can be comparable to the warming caused by doubling CO2 in magnitude, and that this dispersion bias is likely near its maximum for ambient clouds. Relative dispersion is empirically expressed as a function of the quotient between cloud liquid water content and droplet concentration (i.e., water per droplet), yielding an analytical formulation for the first aerosol indirect effect. Further analysis of the new expression reveals that the dispersion effect not only offsets the cooling from the Twomey effect, but is also proportional to the Twomey effect in magnitude. These results suggest that unrealistic representation of relative dispersion in cloud parameterization in general, and evaluation of aerosol indirect effects in particular, is at least in part responsible for several outstanding puzzles of the aerosol-cloud conundrum: for example, overestimation of cloud radiative cooling by climate models compared to satellite observations; large uncertainty and discrepancy in estimates of the aerosol indirect effect; and the lack of interhemispheric difference in cloud albedo.

AN - 69872227; 19068806 AB - Uranium contamination of the environment from mining and milling operations, nuclear-waste disposal, and ammunition use is a widespread global problem. Natural attenuation processes such as bacterial reductive precipitation and immobilization of soluble uranium is gaining much attention. However, the presence of naturally occurring organic ligands can affect the precipitation of uranium. Here, we report that the anaerobic spore-forming bacteria Clostridia, ubiquitous in soils, sediments, and wastes, capable of reduction of Fe(III) to Fe(II), Mn(IV) to Mn(II), U(VI) to U(IV), Pu(IV) to Pu(III), and Tc(VI) to Tc(IV); reduced U(VI) associated with citric acid in a dinuclear 2:2 U(VI): citric acid complex to a biligand mononuclear 1:2 U(IV):citric acid complex,which remained in solution, in contrast to reduction and precipitation of uranium. Our findings show that U(VI) complexed with citric acid is readily accessible as an electron acceptor despite the inability of the bacterium to metabolize the complexed organic ligand. Furthermore, it suggests that the presence of organic ligands at uranium-contaminated sites can affect the mobility of the actinide under both oxic and anoxic conditions by forming such soluble complexes.

AN - 69697035; 18775489 AB - Clustered DNA damages-multiple oxidized bases, abasic sites, or strand breaks within a few helical turns-are potentially mutagenic and lethal alterations induced by ionizing radiation. Endogenous clusters are found at low frequencies in unirradiated normal human cells and tissues. Radiation-sensitive hematopoietic cells with low glycosylase levels (TK6 and WI-L2-NS) accumulate oxidized base clusters but not abasic clusters, indicating that cellular repair genotype affects endogenous cluster levels. We asked whether other factors, i.e., in the cellular microenvironment, affect endogenous cluster levels and composition in hematopoietic cells. TK6 and WI-L2-NS cells were grown in standard medium (RPMI 1640) alone or supplemented with folate and/or selenium; oxidized base cluster levels were highest in RPMI 1640 and reduced in selenium-supplemented medium. Abasic clusters were low under all conditions. In primary hematopoietic stem and progenitor cells from four non-tobacco-using donors, cluster levels were low. However, in cells from tobacco users, we observed high oxidized base clusters and also abasic clusters, previously observed only in irradiated cells. Protein levels and activity of the abasic endonuclease Ape1 were similar in the tobacco users and nonusers. These data suggest that in highly damaging environments, even normal DNA repair capacity can be overwhelmed, leaving highly repair-resistant clustered damages.

The recombinant mcrA minus BL21(DE3) host produces active McrA as evidenced by its acquired ability to selectively restrict the growth of T7 phage containing DNA methylated in vitro by HpaII methylase. The mcrA coding region contains several non- optimal E. coli triplets. Addition of the pACYC-RIL tRNA encoding plasmid to the BL21(DE3) host increased the yield of recombinant McrA (rMcrA) upon induction about 5- to 10-fold. McrA protein expressed at 37 C is insoluble but a significant fraction is recovered as soluble protein after autoinduction at 20 C. rMcrA protein, which is predicted to contain a Cys sub(4)-Zn super(2+) finger and a catalytically important histidine triad in its putative nuclease domain, binds to several metal chelate resins without addition of a poly-histidine affinity tag. This feature was used to develop an efficient protocol for the rapid purification of nearly homogeneous rMcrA. The native protein is a dimer with a high a-helical content as measured by circular dichroism analysis. Under all conditions tested purified rMcrA does not have measurable nuclease activity on HpaII methylated (Cm super(5)CGG) DNA, although the purified protein does specifically bind HpaII methylated DNA. These results have implications for understanding the in vivo activity of McrA in "restricting" m super(5)C-containing DNA and suggest that rMcrA may have utility as a reagent for affinity purification of DNA fragments containing m super(5)C residues.

13266380 AB - Relatively recently, inorganic colloids have been invoked to reconcile the apparent contradictions between expectations based on classical dissolved-phase Pu transport and field observations of 'enhanced' Pu mobility (Kersting et al. Nature 1999, 397, 56-59). A new paradigm for Pu transport is mobilization and transport via biologically produced ligands. This study for the first time reports a new finding of Pu being transported, at sub-pM concentrations, by a cutin-like natural substance containing siderophore-like moieties and virtually all mobile Pu. Most likely, Pu is complexed by chelating groups derived from siderophores that are covalently bound to a backbone of cutin-derived soil degradation products, thus revealing the history of initial exposure to Pu. Features such as amphiphilicity and small size make this macromolecule an ideal collector for actinides and other metals and a vector for their dispersal. Cross-linking to the hydrophobic domains (e.g., by polysaccharides) gives this macromolecule high mobility and a means of enhancing Pu transport. This finding provides a new mechanism for Pu transport through environmental systems that would not have been predicted by Pu transport models.

AN - 69546696; 18658150 AB - Clostridium botulinum neurotoxins are the most potent toxins to humans. The recognition and cleavage of SNAREs are prime evente in exhibiting their toxicity. We report here the crystal structure of the catalytically active full-length botulinum serotype E catalytic domain (BoNT E) in complex with SNAP-25 (a SNARE protein) substrate peptide Arg(180)-Ile(181)-Met(182)-Glu(183) (P1-P3'). It is remarkable that the peptide spanning the scissile bond binds to but bypasses cleavage by the enzyme and inhibits the catalysis fairly with K(i) approximately 69 microm. The inhibitory peptide occupies the active site of BoNT E and shows well defined electron density. The catalytic zinc and the conserved key residue Tyr(350) of the enzyme facilitate the docking of Arg(180) (P1) by interacting with its carbonyl oxygen that displaces the nucleophilic water. The general base Glu(212) side chain interacts with the main chain amino group of P1 and P1'. Conserved Arg(347) of BoNT E stabilizes the proper docking of the Ile(181) (P1') main chain, whereas the hydrophobic pockets stabilize the side chains of Ile(181) (P1') and Met(182) (P2'), and the 250 loop stabilizes Glu(183) (P3'). Structural and functional analysis revealed an important role for the P1' residue and S1' pocket in driving substrate recognition and docking at the active site. This study is the first of its kind and rationalizes the substrate cleavage strategy of BoNT E.

AN - 69572334; 18513362 AB - We studied modulation of the P300 by monetary reward expected to be received on a sustained attention task in 18 individuals with current cocaine use disorders (CUD) and 18 control subjects. Results in the controls revealed sensitivity to money as measured with P300 amplitude and speed of behavioral response and their intercorrelations. In contrast, despite generally faster P300 waveforms and higher self-reported interest in the task, individuals with CUD did not display these responses to money versus nonreward; at the behavioral level, this impairment correlated with frequency of recent cocaine use. These preliminary results suggest a compromised sensitivity to a secondary reinforcer in CUD. This deficit, which needs to be replicated in larger samples of people with currently active versus abstaining CUD, may underlie the compromised ability to advantageously modify behavior in response to changing inner motivations and environmental contingencies.

AN - 69498014; 18712423 AB - BACKGROUND, AIM, AND SCOPEThe subsurface at the Oak Ridge Field Research Center represents an extreme and diverse geochemical environment that places different stresses on the endogenous microbial communities, including low pH, elevated nitrate concentrations, and the occurrence of heavy metals and radionuclides, including hexavalent uranium [U(VI)]. The in situ immobilization of U(VI) in the aquifer can be achieved through microbial reduction to relatively insoluble U(IV). However, a high redox potential due to the presence of nitrate and the toxicity of heavy metals will impede this process. Our aim is to test biostimulation of the endogenous microbial communities to improve nitrate reduction and subsequent U(VI) reduction under conditions of elevated heavy metals.MATERIALS AND METHODSColumn experiments were used to test the possibility of using biostimulation via the addition of ethanol as a carbon source to improve nitrate reduction in the presence of elevated aqueous nickel. We subsequently analyzed the composition of the microbial communities that became established and their potential for U(VI) reduction and its in situ immobilization.RESULTSPhylogenetic analysis revealed that the microbial population changed from heavy metal sensitive members of the actinobacteria, alpha- and gamma-proteobacteria to a community dominated by heavy metal resistant (nickel, cadmium, zinc, and cobalt resistant), nitrate reducing beta- and gamma-proteobacteria, and sulfate reducing Clostridiaceae. Coincidentally, synchrotron X-ray absorption spectroscopy analyses indicated that the resulting redox conditions favored U(VI) reduction transformation to insoluble U(IV) species associated with soil minerals and biomass.DISCUSSIONThis study shows that the necessary genetic information to adapt to the implemented nickel stress resides in the endogenous microbial population present at the Oak Ridge FRC site, which changed from a community generally found under oligotrophic conditions to a community able to withstand the stress imposed by heavy metals, while efficiently reducing nitrate as electron donor. Once nitrate was reduced efficient reduction and in situ immobilization of uranium was observed.CONCLUSIONSThis study provides evidence that stimulating the metabolism of the endogenous bacterial population at the Oak Ridge FRC site by adding ethanol, a suitable carbon source, results in efficient nitrate reduction under conditions of elevated nickel, and a decrease of the redox potential such that sulfate and iron reducing bacteria are able to thrive and create conditions favorable for the reduction and in situ immobilization of uranium. Since we have found that the remediation potential resides within the endogenous microbial community, we believe it will be feasible to conduct field tests.RECOMMENDATIONS AND PERSPECTIVESBiostimulation of endogenous bacteria provides an efficient tool for the successful in situ remediation of mixed-waste sites, particularly those co-contaminated with heavy metals, nitrate and radionuclides, as found in the United States and other countries as environmental legacies of the nuclear age.

AN - 69446154; 18566042 AB - The biodistribution of [1-(14)C]ethanol in rodents was examined to determine sites of concentration of ethanol or its metabolites that may contribute to its toxicological and pharmacokinetic characteristics. After i.v. administration of [1-(14)C]ethanol in mice, radioactivity showed a widespread distribution among body organs. Determination of the proportion of tissue radioactivity accounted for by volatile [1-(14)C]ethanol versus nonvolatile (14)C metabolites indicated that tissue radioactivity was mostly in the form of the latter, even as early as 5 min after injection, indicating a rapid metabolism of the radiolabeled ethanol to labeled metabolites. In a separate study, radioactivity was imaged using whole-body autoradiography after i.v. administration in rats. High levels of radioactivity were observed in the Harderian gland, preputial gland, and pancreas at 15 and 60 min after injection. High levels of radioactivity were also apparent at the later time point in the intestinal tract, indicating hepatobiliary excretion of radiolabeled metabolites. Moderate levels of radioactivity were present in the liver, lungs, salivary glands, bone marrow, and kidney cortex. In conclusion, after i.v. [(14)C]ethanol administration, radioactivity initially distributes widely among body organs but concentrates in specific tissues at subsequent time points. Especially notable in the current study was the high concentration of radioactivity accumulating in the pancreas. It is thus tempting to speculate that the well documented high incidence of pancreatic disease observed in human chronic alcoholism may be related to a propensity of this organ to accumulate ethanol and/or reactive ethanol metabolites.

The Centers for Disease Control and Prevention (CDC) has declared them as Category A biowarfare agents. The most potent among them, botulinum neurotoxin type A (BoNT/A), cleaves its substrate synaptosome-associated protein of 25 kDa (SNAP-25). An efficient drug for botulism can be developed only with the knowledge of interactions between the substrate and enzyme at the active site. Here, we report the crystal structures of the catalytic domain of BoNT/A with its uncleavable SNAP-25 peptide super(197)QRATKM super(202) and its variant super(197)RRATKM super(202) to 1.5 Aa and 1.6 Aa, respectively. This is the first time the structure of an uncleavable substrate bound to an active botulinum neurotoxin is reported and it has helped in unequivocally defining S1 to S5' sites. These substrate peptides make interactions with the enzyme predominantly by the residues from 160, 200, 250 and 370 loops. Most notably, the amino nitrogen and carbonyl oxygen of P1 residue (Gln197) chelate the zinc ion and replace the nucleophilic water. The P1'-Arg198, occupies the S1' site formed by Arg363, Thr220, Asp370, Thr215, Ile161, Phe163 and Phe194. The S2' subsite is formed by Arg363, Asn368 and Asp370, while S3' subsite is formed by Tyr251, Leu256, Val258, Tyr366, Phe369 and Asn388. P4'-Lys201 makes hydrogen bond with Gln162. P5'-Met202 binds in the hydrophobic pocket formed by the residues from the 250 and 200 loop. Knowledge of interactions between the enzyme and substrate peptide from these complex structures should form the basis for design of potent inhibitors for this neurotoxin. Author Summary Botulinum neurotoxins are the most poisonous substance to humans. The ease with which the bacteria can be grown, its potency and persistence have made it a potential bioterrorism agent, and accordingly, botulinum neurotoxin has been declared as Category A agent by the Centers of Disease Control and Prevention. Since it is both a potential bioweapon and a bioterrorism agent, it is imperative to develop counter measures and therapeutics for these neurotoxins, as none are available so far except experimental vaccines and an FDA-approved equine antitoxin. Our work presented here is an important milestone towards achieving this goal. The best antidote can be developed by blocking the active site of any enzyme. The crystal structures of substrate peptide-enzyme complex presented here map the interactions between the two and provide critical information for designing effective drugs against this toxin.

The Fe and Co K-edge XAS results showed that the major charge compensation at the metal sites during charge is achieved by the oxidation of Fe[super]2+ ions at lower potential plateau ([not, vert, similar]3.6 V) and the oxidation of Co[super]2+ ions at higher potential plateau ([not, vert, similar]5.0 V). The gradual shift of main edge features in P K-edge XANES spectra showed that P[single bond]O bonds become less covalent during delithiation, due to the increased covalency of Fe[super]3+[single bond]O bonds via the inductive effect. From the observation of pre-edge peaks, it is concluded that the electrochemical delithiation of Li sub(1-xFePO) sub(4) result in the hybridization of P 3p states with the metal 3d states.

Skeletal tissue samples from 135 individuals from an early nineteenth century Philadelphia cemetery (First African Baptist Church) were studied by electrothermal atomic absorption spectrometry and X-ray fluorescence for lead content. High bone lead levels led to investigation of possible diagenetic effects. These were investigated by several different approaches including distribution of lead within bone by X-ray fluorescence, histological preservation, soil lead concentration and acidity as well as location and depth of burial. Bone lead levels were very high in children, exceeding those of the adult population that were buried in the cemetery, and also those of present day adults. The antemortem age-related increase in bone lead, reported in other studies, was not evidenced in this population. Lead was evenly deposited in areas of taphonomic bone destruction. Synchrotron X-ray fluorescence studies revealed no consistent pattern of lead microdistribution within the bone. Our conclusions are that post-mortem diagenesis of lead ion has penetrated these archaeological bones to a degree that makes their original bone lead content irretrievable by any known method. Increased bone porosity is most likely responsible for the very high levels of lead found in bones of newborns and children. Copyright John Wiley & Sons. Reproduced with permission.

This paper revisits and extends the cloud tomography method by rigorously examining the nature of the resultant mathematical problem and its close relationship to the physical configuration of microwave radiometers. The singular value decomposition (SVD) analysis reveals that the retrieval of cloud LWC fields from microwave emission is highly ill-posed, and requires special techniques to solve it. The truncated SVD approach along with the L-curve method for choosing the optimal truncating point is used to obtain a better retrieval of cloud LWC. A group of sensitivity studies show that the retrieval accuracy is determined by several factors, including the number of radiometers, the spatial resolution of output, the number of scanning angles, the radiometer characteristics (e.g., noise level, beam width), the physical arrangement of radiometers, and the uncertainty in the ancillary temperature and water vapor mixing ratio data. When more radiometers and/or more scanning angles are used, and/or the radiometer beam width is reduced, and/or when a coarser output resolution is acceptable, the retrieval problem becomes less ill-posed, and a better retrieval can be obtained. Moreover, the observation system simulations demonstrate that the cloud tomography method is able to retrieve the cloud structures generated by cloud resolving models with a good accuracy. For a setup consisting of four microwave radiometers of typical noise level 0.3 K, the tomography method is capable of retrieving the LWC to within 5% of the maximum LWC in the simulated stratocumulus and broken cumulus cases, with a spatial resolution of a few hundred meters.

These serotypes are highly specific in their proteolytic cleavage of SNAP-25 (synaptosomal-associated protein of 25 kDa), VAMP (vesicle associated membrane protein) or syntaxin. The catalytic domain (light chain, LC) of the neurotoxin has a Zn super(2+) dependent endopeptidase activity. In order to design drugs and inhibitors against these toxins, high level overexpression and characterization of LC of BoNTs along with the development of assays to monitor their proteolytic activity becomes important. Using the auto-induction method, we attained a high level expression of BoNT/C1(1-430) yielding more than 30 mg protein per 500 ml culture. We also developed an efficient assay to measure the activity of serotype C1 based on a HPLC method. SNAP-25 with varying peptide length has been reported in literature as substrates for BoNT/C1 proteolysis signifying the importance of remote exosites in BoNT/C1 required for activity. Here, we show that a 17-mer peptide corresponding to residues 187-203 of SNAP-25, which has earlier been shown to be a substrate for BoNT/A, can be used as a substrate for quantifying the activity of BoNT/C1(1-430). There was no pH dependence for the proteolysis, however the presence of dithiothreitol is essential for the reaction. Although the 17-mer substrate bound 110-fold less tightly to BoNT/C1(1-430) than SNAP-25, the optimal assay conditions facilitated an increase in the catalytic efficiency of the enzyme by about 5- fold.

Botulinum neurotoxin type A is the most potent among the clostridial neurotoxins, and to date there is no post-exposure therapeutic intervention available. To develop inhibitors leading to drug design, it is imperative that critical interactions between the enzyme and the substrate near the active site are known. Although enzyme-substrate interactions at exosites away from the active site are mapped in detail for botulinum neurotoxin type A, information about the active site interactions is lacking. Here, we present the crystal structures of botulinum neurotoxin type A catalytic domain in complex with four inhibitory substrate analog tetrapeptides, viz. RRGC, RRGL, RRGI, and RRGM at resolutions of 1.6-1.8Aa. These structures show for the first time the interactions between the substrate and enzyme at the active site and delineate residues important for substrate stabilization and catalytic activity. We show that OH of Tyr super(366) and NH sub(2) of Arg super(363) are hydrogen-bonded to carbonyl oxygens of P1 and P1' of the substrate analog and position it for catalytic activity. Most importantly, the nucleophilic water is replaced by the amino group of the N-terminal residue of the tetrapeptide. Furthermore, the S1' site is formed by Phe super(194), Thr super(215), Thr super(220), Asp super(370), and Arg super(363). The K sub(i) of the best inhibitory tetrapeptide is 157 nM.

AN - 69162091; 18418874 AB - Dopamine (DA) D2 receptor (D2R) agonists and antagonists can modulate self-administration behavior, conditioned place preference, and locomotor responses to cocaine. Low levels of D2R have also been observed in cocaine addicted subjects and in non human primates after chronic cocaine exposures. Prior studies had shown that D2R upregulation in the nucleus accumbens (NAc) in rodents trained to self-administer alcohol markedly attenuated alcohol preference and intake. Here we assess the effects of D2R upregulation in the NAc on cocaine intake in rats trained to self-administer cocaine. Following 2 weeks of i.v. cocaine self-administration (CSA), rats were stereotaxically treated with an adenovirus that carried the D2R gene to upregulate D2R in the NAc. D2R vector treatment resulted in a significant decrease (75%) in cocaine infusions and lever presses (70%) for cocaine. This effect lasted 6 days before cocaine consumption returned to baseline levels, which corresponds roughly to the time it takes D2R to return to baseline levels. These findings show that CSA and D2R in the NAc are negatively correlated and suggest that cocaine intake is modulated in part by D2R levels in NAc. Thus strategies aimed at increasing D2R expression in NAc may be beneficial in treating cocaine abuse and addiction. JF - Synapse (New York, N.Y.)

The bacteria were incubated with (i) 0.1 mM Ce(III), (ii) 1 mM Mn(II), and, (iii) 0.1 mM Ce(III) and 1 mM Mn(II) for 288 h at 30 degrees C, and the oxidation states of Ce and Mn then were measured by X-ray Absorption Near Edge Structure (XANES). We also determined the elemental distributions in the bacteria and precipitates by Scanning-Proton Induced X-ray Emission (S-PIXE). In the absence of Mn(II), the concentration of Ce rapidly decreased to 0.03 mM, increased to 0.06 mM, and then remained there. In the presence of Mn(II), the concentration of Ce fell rapidly to approximately 0.015 mM, and then rose to 0.05 mM, and finally declined to 0.005; a black precipitate containing Mn was formed during this last phase. Mn-bearing precipitates also formed in the medium containing only Mn. XANES analysis of the precipitate revealed the presence of Mn(III) and (IV), and Ce (III) and (IV). Ce (III) was detected in solution, and with the bacteria. S-PIXE analyses of the precipitates showed that Ce was associated with Mn, and not with the bacteria. These results suggest that the precipitation of Ce is preceded by its accumulation by the bacterium, followed by its oxidization to Ce(IV) by the Mn(III, IV)-containing precipitates that the bacteria generate.

The six proteins of the Saccharomyces cerevisiae ORC that form a stable complex bind to origins of DNA replication and recruit prereplicative complex (pre-RC) proteins, one of which is Cdc6. To further understand the function of ORC we recently determined by single-particle reconstruction of electron micrographs a low-resolution, 3D structure of S. cerevisiae ORC and the ORC-Cdc6 complex. In this article, the spatial arrangement of the ORC subunits within the ORC structure is described. In one approach, a maltose binding protein (MBP) was systematically fused to the N or the C termini of the five largest ORC subunits, one subunit at a time, generating 10 MBP-fused ORCs, and the MBP density was localized in the averaged, 2D EM images of the MBP-fused ORC particles. Determining the Orc1-5 structure and comparing it with the native ORC structure localized the Orc6 subunit near Orc2 and Orc3. Finally, subunit-subunit interactions were determined by immunoprecipitation of ORC subunits synthesized in vitro. Based on the derived ORC architecture and existing structures of archaeal Orc1-DNA structures, we propose a model for ORC and suggest how ORC interacts with origin DNA and Cdc6. The studies provide a basis for understanding the overall structure of the pre-RC.

Our algorithm enables automatic recovery of the amplitude and phase of the complex-valued objects with diffraction-limited resolution, starting from selected-area electron diffraction (SAED) patterns recorded from partially overlapping regions in STEM/CTEM. Based on a 'differential map' (DM) approach, the ACD algorithm meets very general requirements and, similar to 'hybrid input-output' (HIO) algorithm, can be applied to non-periodic, real or complex structures. In contrast to many other algorithms, it is not limited by the object's finite size or tight object support. Wide-field-of-view reconstructions for the complex-object-wave amplitude and phase made with ACD algorithm from SAED patterns down to sub-Angstrom resolution show the potential of diffractive imaging for quantitative analysis of functional materials at different length scales in terms of absorption and scattering mechanisms.

Materials that have served the nuclear sector well may not be suitable to play such a role which demands that the material comprising the beam-intercepting element must, in addition to the long exposure which leads to accumulated irradiation damage, also endure short exposure that manifests itself as thermo-mechanical shock. The ability of materials to resist irradiation-induced degradation of its properties that control shock and fatigue is of primary interest. The need for such materials that extend beyond resistance to the neutron-driven irradiation damage of reactor components has led to an extensive search and experimentation with new alloys and composites. These new high-performance materials, which appear to possess the right combination of mechanical and physical properties, are explored through a multi-phased experimental study at Brookhaven National Laboratory (BNL). This study, which brings together the interest in accelerator targets of different facilities around the world, seeks to simulate conditions of both short and long exposure to proton beams to assess the survivability potential of these new alloys and composite materials. While thermo-mechanical shock effects have been studied in the early stages of this comprehensive effort, it is irradiation damage that is currently the focus of the study and results to-date are presented in this paper along with the status and objectives of on-going studies. Of special interest are results depicting damage reversal through post-irradiation annealing in some of the materials. High fluences of 200 and/or 117 MeV protons provided by the BNL Linac beam that serves the Isotope Production Facility were used to assess irradiation damage in these new composites and alloys.

After initial characterization of the impact of the plume caused by an RDD, there will be considerable pressure from the public to allow them to return and quickly collect their belongings, and, eventually, to reoccupy residences and to reopen businesses. The FRMAC procedures principally deal with early and intermediate phase dose assessment, but do include late phase assessment procedures. However, the late phase assessments do not include complex geometries, such as the internal structure of buildings. This paper identifies areas where more specificity is needed to rapidly provide assessments to health officials and senior decision-makers. In this regard, there is no national consensus method to calculate projected dose inside buildings after an RDD event that addresses selecting the exposure pathways, scenarios, key parameters, etc. Therefore, to demonstrate an approach that exemplifies some of the technical and policy issues, which are unresolved, four exposure scenarios (residential, industrial, public park, park worker) were evaluated to determine the level of contamination that would deliver a dose equivalent of 10 mSv in the first year, excluding exposure during the first 4 d (emergency phase). In addition, the retrieval of personal belongings was simulated by assessing a 1-h exposure for the residential and industrial scenarios. RESRAD-BUILD was used to calculate the surface concentration of 60Co, 90Sr, 137Cs, 192Ir, 226Ra, 238Pu, 241Am, and 252Cf that would lead to a 10 mSv reference dose for these exposure periods. These example studies are intended to provide insights and guidance on how a municipal health agency can begin to develop a response plan, and to understand how the assessment process will determine the dose impacts resulting from an RDD event. The model's predictions heavily depend on the choice of the model's parameters; for several key ones, there are large uncertainties about their appropriate values. To avoid having to make hasty decisions during an emergency after an RDD attack, this analysis demonstrates that a detailed protocol for calculating dose should be developed prospectively so that decision-makers already are fully familiar with the process and its ensuing products.

AN - 69185507; 18353858 AB - Clustered damages-two or more closely opposed abasic sites, oxidized bases or strand breaks-are induced in DNA by ionizing radiation and by some radiomimetic drugs. They are potentially mutagenic or lethal. High complexity, multilesion clusters (three or more lesions) are hypothesized as repair-resistant and responsible for the greater biological damage induced by high linear energy transfer radiation (e.g. charged particles) than by low linear energy transfer X- or gamma-rays. We tested this hypothesis by assessing human abasic endonuclease Ape1 activity on two- and multiple-lesion abasic clusters. We constructed cluster-containing oligonucleotides using a central variable cassette with abasic site(s) at specific locations, and 5' and 3' terminal segments tagged with visually distinctive fluorophores. The results indicate that in two- or multiple-lesion clusters, the spatial arrangement of uni-sided positive [in which the opposing strand lesion(s) is 3' to the base opposite the reference lesion)] or negative polarity [opposing strand lesion(s) 5' to the base opposite the reference lesion] abasic clusters is key in determining Ape1 cleavage efficiency. However, no bipolar clusters (minimally three-lesions) were good Ape1 substrates. The data suggest an underlying molecular mechanism for the higher levels of biological damage associated with agents producing complex clusters: the induction of highly repair-resistant bipolar clusters.

AN - 70414591; 18355684 AB - INTRODUCTIONThe only radiotracer available for the selective imaging of muscarinic M2 receptors in vivo is 3-(3-(3-[18F]fluoropropyl)thio)-1,2,5-thiadiazol-4-yl)-1,2,5,6-tetrahydro-1-methylpyridine) ([18F]FP-TZTP). We have prepared and labeled 3-(3-(3-fluoropropylthio)-1,2,5-thiadiazol-4-yl)-1,2,5,6-tetrahydro-1-methylpyridne (FP-TZTP, 3) and two other TZTP derivatives with 11C at the methylpyridine moiety to explore the potential of using 11C-labeled FP-TZTP for positron emission tomography imaging of M2 receptors and to compare the effect of small structural changes on tracer pharmacokinetics (PK) in brain and peripheral organs.METHODS11C-radiolabeled FP-TZTP, 3-(3-propylthio)-TZTP (6) and 3,3,3-(3-(3-trifluoropropyl)-TZTP (10) were prepared, and log D, plasma protein binding (PPB), affinity constants, time-activity curves (TACs), area under the curve (AUC) for arterial plasma, distribution volumes (DV) and pharmacological blockade in baboons were compared.RESULTSValues for log D, PPB and affinity constants were similar for 3, 6 and 10. The fraction of parent radiotracer in the plasma was higher and the AUC lower for 10 than for 3 and 6. TACs for brain regions were similar for 3 and 6, which showed PK similar to the 18F tracer, while 10 showed slower uptake and little clearance over 90 min. DVs for 3 and 6 were similar to the 18F tracer but higher for 10. Uptake of the three tracers was significantly reduced by coinjection of unlabeled 3 and 6.CONCLUSIONSmall structural variations on the TZTP structure greatly altered the PK in brain and behavior in blood with little change in the log D, PPB or affinity. The study suggests that 11C-radiolabeled 3 will be a suitable alternative to [18F]FP-TZTP for translational studies in humans.

AN - 70195920; 18188044 AB - Traditionally, the concept of As Low As Reasonably Achievable (ALARA) has been applied to the workplace and to protect the public. The goals are to minimize small incremental exposures on a daily basis or per specific task, and on a yearly basis, thereby to keep the total annual dose equivalent as far below regulatory limits as practical. In an extreme emergency caused by radiological or nuclear terrorism, or a large scale radiological accident, it is proposed that the same principles can be applied to protect First Responders against potentially large exposures.

If the process is accompanied by effective control over the interactions between the blocks and all entropic effects, then the resultant structures will be ordered with a precision hard to achieve with other fabrication methods. But it remains challenging to use self-assembly to design systems comprised of different types of building blocks-to realize novel magnetic, plasmonic and photonic metamaterials, for example. A conceptually simple idea for overcoming this problem is the use of 'encodable' interactions between building blocks; this can in principle be straightforwardly implemented using biomolecules. Strategies that use DNA programmability to control the placement of nanoparticles in one and two dimensions have indeed been demonstrated. However, our theoretical understanding of how to extend this approach to three dimensions is limited, and most experiments have yielded amorphous aggregates and only occasionally crystallites of close-packed micrometre-sized particles. Here, we report the formation of three-dimensional crystalline assemblies of gold nanoparticles mediated by interactions between complementary DNA molecules attached to the nanoparticles' surface. We find that the nanoparticle crystals form reversibly during heating and cooling cycles. Moreover, the body-centred- cubic lattice structure is temperature-tuneable and structurally open, with particles occupying only approx4% of the unit cell volume. We expect that our DNA-mediated crystallization approach, and the insight into DNA design requirements it has provided, will facilitate both the creation of new classes of ordered multicomponent metamaterials and the exploration of the phase behaviour of hybrid systems with addressable interactions.

Satellite-borne sensors measure the mean intensities emanating from heterogeneous vegetated pixels. The theory of radiative transfer in stochastic media provides the most logical linkage between satellite observations and the three-dimensional canopy structure through a closed system of simple equations which contains the mean intensity and higher statistical moments directly as its unknowns. Although this theory has been a highly active research field in recent years, its potential for satellite remote sensing of vegetated surfaces has not been fully realized because of the lack of models of a canopy pair-correlation function that the stochastic radiative transfer equations require. The pair correlation function is defined as the probability of finding simultaneously phytoelements at two points. This paper presents analytical and Monte Carlo generated pair correlation functions. Theoretical and numerical analyses show that the spatial correlation between phytoelements is primarily responsible for the effects of the three-dimensional canopy structure on canopy reflective and absorptive properties. The pair correlation function, therefore, is the most natural and physically meaningful measure of the canopy structure over a wide range of scales. The stochastic radiative transfer equations naturally admit this measure and thus provide a powerful means to investigate the three-dimensional canopy structure from space. Canopy reflectances predicted by the stochastic equations are assessed by comparisons with the PARABOLA measurements from coniferous and broadleaf forest stands in the BOREAS Southern Study Areas. The pair correlation functions are derived from data on tree structural parameters collected during field campaigns conducted at these sites. The simulated canopy reflectances compare well with the PARABOLA data.

In this strategy, animals are injected intravenously (i.v.) through a catheterized line and permitted to move freely for 30 min during uptake of the imaging agent, in this case super(11)C-raclopride. After this Awake Uptake period, animals are anesthetized and scanned for 25 min. We tested the utility of this strategy for measuring changes in striatal super(11)C-raclopride binding under control conditions (awake and freely moving in the home cage) and with several drug challenges: a loading dose of unlabeled raclopride, pretreatment with methamphetamine (METH) or pretreatment with gamma -vinyl-GABA [S(+)-GVG] followed by METH. An additional group of animals underwent a stress paradigm that we have previously shown increases brain dopamine. For drug challenge experiments, the change in super(11)C-raclopride binding was compared to data from animals that were anesthetized for the uptake period ("Anesthetized Uptake") and full time activity curves were used to calculate super(11)C-raclopride binding. Regardless of the drug treatment protocol, there was no difference in super(11)C-raclopride striatum to cerebellum ratio between the Awake versus the Anesthetized Uptake conditions. Awake and Anesthetized groups demonstrated over 90% occupancy of dopamine receptors with a loading dose of cold raclopride, both groups demonstrated a 30% reduction in super(11)C-raclopride binding from METH pretreatment and this effect was modulated to the same degree by GVG under both uptake conditions. Restraint during Awake Uptake decreased super(11)C-raclopride binding by 29%. These studies support a unique molecular imaging strategy in which radiotracer uptake occurs in freely moving animals, after which they are anesthetized and scanned. This imaging strategy extends the applicability of small animal PET to include functional neurotransmitter imaging and the neurochemical correlates of behavioral tasks.

Distention is one of the mechanisms that modulates food intake. We measured regional brain activation during dynamic gastric balloon distention in 18 health subjects using functional magnetic resonance imaging and the blood oxygenation level-dependent (BOLD) responses. The BOLD signal was significantly changed by both inflow and outflow changes in the balloon's volume. For lower balloon volumes, water inflow was associated with activation of sensorimotor cortices and right insula. The larger volume condition additionally activated left posterior amygdala, left posterior insula and the left precuneus. The response in the left amygdala and insula was negatively associated with changes in self-reports of fullness and positively with changes in plasma ghrelin concentration, whereas those in the right amygdala and insula were negatively associated with the subject's body mass index. The widespread activation induced by gastric distention corroborates the influence of vagal afferents on cortical and subcortical brain activity. These findings provide evidence that the left amygdala and insula process interoceptive signals of fullness produced by gastric distention involved in the controls of food intake.

Abuse results in rapid onset and short-lasting effects that include visual hallucinations and motor- function impairment. Salvinorin A, the psychoactive component of S. divinorum, is a uniquely potent agonist at [kappa]-opioid receptors, targets for new therapeutic drugs. We labeled salvinorin A with C-11 by acylation of salvinorin B with [ super(11)C]-acetyl chloride to study whether its kinetic behavior in the brain parallels its uniquely fast, yet brief physiological effects. Positron emission tomography (PET) studies performed in 6 adult female baboons indicated extremely rapid brain uptake reaching a peak accounting for 3.3% of the total administered dose in 40 s and clearing with a half-life of 8 min. [ super(11)C]-salvinorin A was distributed throughout the brain with the highest concentration in the cerebellum and a notable concentration in the visual cortex, perhaps accounting for its physiological effects when smoked. Naloxone administration did not reduce the overall concentration of [ super(11)C]-salvinorin A significantly nor did it change its regional distribution. Peripheral organ kinetics suggested at least two modes of metabolism and excretion occur: through the renal and biliary systems. Our findings have revealed that the exceptionally rapid uptake and brief duration of salvinorin A in the brain match the time-course of visual hallucinations for S. divinorum when smoked. The effects of salvinorin A may occur at < 10 mu g in the human brain, emphasizing its remarkable potency.

We have determined the three-dimensional crystal structures of HutI from Agrobacterium tumefaciens (At-HutI) and an environmental sample from the Sargasso Sea Ocean Going Survey (Es-HutI) bound to the product [N-formimino-L-glutamate (NIG)] and an inhibitor [3- (2,5-dioxoimidazolidin-4-yl)propionic acid (DIP)], respectively. In both structures, the active site is contained within each monomer, and its organization displays the landmark feature of the amidohydrolase superfamily, showing a metal ligand (iron), four histidines, and one aspartic acid.

In this study, effluents of an industrial dye producer were subjected to distinct treatment trains following an initial qualitative characterization. The effectiveness of ozonation and a treatment using white rot fungi (WRF) and their enzymes were compared with respect to parameters such as residual color, toxicity on human cells, and genotoxicity. A combined ozonation/WRF process was also investigated. The effluent exhibited significant toxicity that was reduced by only 10% through ozonation, whereas the fungal treatment achieved a 35% reduction. A combined treatment (ozone/WRF) caused an abatement of the toxicity by more than 70%. In addition, the initial genotoxicity of the effluent was still present after the ozone treatment, while it was completely removed through the fungal treatment.

A series of selection criteria are imposed to eliminate data points with non-urban emission influences. Biomass burning has urban and non-urban sources that are distinguished on the basis of CH sub(3)CN and CO. In order to account for dilution in the urban plume, aerosol concentrations are normalized to CO which is taken as an inert tracer of urban emission, proportional to the emissions of aerosol precursors. Time evolution is determined with respect to photochemical age defined as -Log sub(10) (NO sub(x)/NO sub(y)). The geographic distribution of photochemical age and CO is examined, confirming the picture that Mexico City is a source region and that pollutants become more dilute and aged as they are advected towards T1 and T2, surface sites that are located at the fringe of the City and 35 km to the NE, respectively. Organic aerosol (OA) per ppm CO is found to increase 7 fold over the range of photochemical ages studied, corresponding to a change in NO sub(x)/NO sub(y) from nearly 100% to 10%. In the older samples the nitrate/CO ratio has leveled off suggesting that evaporation and formation of aerosol nitrate are in balance. In contrast, OA/CO increases with age in older samples, indicating that OA is still being formed. The amount of carbon equivalent to the deduced change in OA/CO with age is 56 ppbC per ppm CO. At an aerosol yield of 5% and 8% for low and high yield aromatic compounds, it is estimated from surface hydrocarbon observations that only similar to 9% of the OA formation can be accounted for. A comparison of OA/CO in Mexico City and the eastern U.S. gives no evidence that aerosol yields are higher in a more polluted environment.

Based on PV production data of 2004-2006, this study presents the life-cycle greenhouse gas emissions, criteria pollutant emissions, and heavy metal emissions from four types of major commercial PV systems: multicrystalline silicon, monocrystalline silicon, ribbon silicon, and thin-film cadmium telluride. Life-cycle emissions were determined by employing average electricity mixtures in Europe and the United States during the materials and module production for each PV system. Among the current vintage of PV technologies, thin-film cadmium telluride (CdTe) PV emits the least amount of harmful air emissions as it requires the least amount of energy during the module production. However, the differences in the emissions between different PV technologies are very small in comparison to the emissions from conventional energy technologies that PV could displace. As a part of prospective analysis, the effect of PV breeder was investigated. Overall, all PV technologies generate far less life-cycle air emissions per GWh than conventional fossil-fuel-based electricity generation technologies. At least 89% of air emissions associated with electricity generation could be prevented if electricity from photovoltaics displaces electricity from the grid.

As MnSOD has been shown to remove superoxide radical with varying efficiency depending upon its cellular origin, a comparison of the Drad MnSOD efficiency with that of both human and Escherichia coli MnSODs was undertaken. Pulse radiolysis studies demonstrate that, under identical ratios of enzyme to superoxide radical, the dismutation efficiencies scaled as Drad MnSOD > E. coli MnSOD > human MnSOD. Further, Drad MnSOD is most effective at high superoxide fluxes found under conditions of high radioactivity. A mechanism is postulated to account for the differences in the activities of the MnSODs that considers the release of peroxide as not always an optimal process.

Complex signaling by molecules within and between cells controls homeostasis and adaptation of the whole organism against perturbations. Energy depositions from ionizing radiation in tissue micro-masses trigger stochastically local molecular events that may result in structural damage with consequent short or long term changes in function. Damage to DNA in a tissue element increases over a certain dose range linearly with the energy deposited. This is a defined risk of DNA damage production by the energy deposition events. A second risk describes the probability of damage propagation from the primary site at the basic level of molecular organization to higher levels of the organism. This second risk depends on both quality and quantity of perturbations received at the basic level, and on the resistance by homeostatic controls against transfer of such damage. The homeostatic signaling that controls the second risk at different levels does not respond to small perturbations in a linear fashion. Moreover, protective responses under homeostatic control at the various levels of biological organization may become up-regulated temporarily and specifically by low level perturbations. These adaptive responses reflect the tolerance of homeostatic control, and, thus, also depend on dose. The low-dose induced temporary up-regulations of protection may operate also against non-radiogenic perturbations; for instance against those from metabolic products, such as reactive oxygen species (ROS). At single cell exposures below at 0.1 Gy, adaptive protections against propagation of non-radiogenic damage often tend to outweigh permanent manifestations of radiogenic damage. The quality and extent of homeostatic responses are under genetic control. Thus, complex systems responses encompass both damage and prevention of further damage and its propagation to higher levels; they are expected to vary among individuals. The balance between health risk and benefit of low-level radiation exposure of any given individual may become predictable by gene-expression profiles in un-irradiated and irradiated tissue cells of this individual at some future time.

It is an integral part of the atmospheric-terrestrial C exchange cycle mediated via photosynthesis; furthermore, it emerged recently as a new trading commodity, i.e., "carbon credits." When carefully manipulated, C sequestration by the soil could balance and mitigate anthropogenic CO sub(2) emissions into the atmosphere that are believed to contribute to global warming. The pressing need for assessing the soil's C stocks at local, regional, and global scales, now in the forefront of much research, is considerably hindered by the problems besetting dry-combustion chemical analyses, even with state-of-the-art procedures. To overcome these issues, we developed a new method based on gamma-ray spectroscopy induced by inelastic neutron scattering (INS). The INS method is an in situ, nondestructive, multielemental technique that can be used in stationary or continuous- scanning modes of operation. The results from data acquired from an investigated soil mass of a few hundred kilograms to an approximate depth of 30 cm are reported immediately. Our initial experiments have demonstrated the feasibility of our proposed approach; we obtained a linear response with C concentration and a detection limit between 0.5 and 1% C by weight.

Under Anaerobic Conditions AN - 19300225; 8133725 AB - An anaerobic, gram positive, spore-forming bacterium Clostridium sp., common in soils and wastes, capable of reduction of Fe(III) to Fe(II), Mn(IV) to Mn(II), Tc(VII) to Tc(IV), and U(VI) to U(IV), reduced Pu(IV) to Pu(III). Addition of super(242)Pu (IV)-nitrate to the bacterial growth medium at pH 6.4 resulted in the precipitation of Pu as amorphous Pu(OH) sub(4) due to hydrolysis and polymerization reactions. The Pu (1 x 10 super(-5) M) had no effect upon growth of the bacterium as evidenced by glucose consumption; carbon dioxide and hydrogen production; a decrease in pH of the medium from 6.4 to 3.0 due to production of acetic and butyric acids from glucose fermentation; and a change in the Eh of the culture medium from +50 to -180 mV. Commensurate with bacterial growth, Pu was rapidly solubilized as evidenced by an increase in Pu concentration in solution which passed through a 0.03 mu m filtration. Selective solvent extraction of the culture by thenoyltrifluoroacetone (TTA) indicated the presence of a reduced Pu species in the soluble fraction. X-ray absorption near edge spectroscopic (XANES) analysis of Pu in the culture sample at the Pu L sub(III) absorption edge (18.054 keV) showed a shift of -3 eV compared to a Pu(IV) standard indicating reduction of Pu(IV) to Pu(III). These results suggest that, although Pu generally exists as insoluble Pu(IV) in the environment, under appropriate conditions, anaerobic microbial activity could affect the long-term stability and mobility of Pu by its reductive dissolution.

The heat capacity of the global ocean, obtained from regression of ocean heat content versus global mean surface temperature, GMST, is 14 + or - 6 W a m (super -2) K (super -1) , equivalent to 110 m of ocean water; other sinks raise the effective planetary heat capacity to 17 + or - 7 W a m (super -2) K (super -1) (all uncertainties are 1-sigma estimates). The time constant pertinent to changes in GMST is determined from autocorrelation of that quantity over 1880-2004 to be 5 + or - 1 a. The resultant equilibrium climate sensitivity, 0.30 + or - 0.14 K/(W m (super -2) ), corresponds to an equilibrium temperature increase for doubled CO (sub 2) of 1.1 + or - 0.5 K. The short time constant implies that GMST is in near equilibrium with applied forcings and hence that net climate forcing over the twentieth century can be obtained from the observed temperature increase over this period, 0.57 + or - 0.08 K, as 1.9 + or - 0.9 W m (super -2) . For this forcing considered the sum of radiative forcing by incremental greenhouse gases, 2.2 + or - 0.3 W m (super -2) , and other forcings, other forcing agents, mainly incremental tropospheric aerosols, are inferred to have exerted only a slight forcing over the twentieth century of -0.3 + or - 1.0 W m (super -2) .

The non-interlocked, globular structure of subunits in the knob trimer implies that trimers assemble from prefolded monomers through a dimer intermediate, but these intermediates have not been observed and the mechanism of assembly therefore remains uncharacterized. Here we report that expression of the Ad serotype 2 (Ad2) knob was toxic for thi- strains of Escherichia coli, which are defective in de novo synthesis of thiamine (vitamin B1). Ad2 knob trimers isolated from a thi+ strain copurified through multiple chromatography steps with a small molecule of mass equivalent to that of thiamine diphosphate (ThDP). Mutant analysis did not implicate any specific site for ThDP binding. Our results suggest that ThDP may associate with assembly intermediates and become trapped in assembled trimers, possibly within one of several large cavities that are partially solvent-accessible or buried completely within the trimer interior.

One of their functions is to complex metals resulting in their precipitation. We investigated the interaction of phosphate and low-molecular-weight PolyP (1400-1900Da) with uranyl ion at various pHs. Potentiometric titration of uranyl ion in the presence of phosphate showed two sharp inflection points at pHs 4 and 8 due to uranium hydrolysis reaction and interaction with phosphate. Titration of uranyl ion and PolyP revealed a broad inflection point starting at pH 4 indicating that complexation of U-PolyP occurs over a wide range of pHs with no uranium hydrolysis. EXAFS analysis of the U-HPO sub(4) complex revealed that an insoluble uranyl phosphate species was formed below pH 6; at higher pH (>=8) uranium formed a precipitate consisting of hydroxophosphato species. In contrast, adding uranyl ion to PolyP resulted in formation of U-PolyP complex over the entire pH range studied. At low pH (=<6) an insoluble U-PolyP complex having a monodentate coordination of phosphate with uranium was observed. Above pH 6 however, a soluble bidentate complex with phosphate and uranium was predominant. These results show that the complexation and solubility of uranium with PO sub(4) and PolyP are dependent upon pH.

AN - 68468974; 17969175 AB - PURPOSETo map the induced magnetic field gradients and estimate the magnetic force in the human head during magnetic resonance imaging at 4 Tesla (T).MATERIALS AND METHODSThe magnetic field distribution in the human head was measured using two gradient-echo experiments with different echo times. The phase of the complex image ratio removed the wrapping artifact, characteristic of phase images, and was used to map the magnetic field distribution and calculate the accurate maps of the magnetic field gradients in the human head.RESULTSThe time-independent gradient fields induced by air/tissue interfaces in the head can be 50 times larger than those resulting from the magnetic field inhomogeneity of the MRI magnet. However, the associated magnetic force in the brain is by far smaller than the gravitational force.CONCLUSIONThe induced gradient fields increase the magnetic force on tissues. However, even for tissue components with large magnetic susceptibility such as iron-containing proteins, this force is negligible compared with the gravitational force. Therefore, this study suggests that static and uniform magnetic fields do not have a significant risk for the tissues in the head.

At present differing explicit or implicit choices of the measure of climate change, of definitions of feedbacks, and of the underlying non-feedback climate to which feedbacks must be referred have resulted in differing measures of feedbacks. The single variable that is most commonly taken as a measure of climate response to radiative perturbation is global (and annual) mean (near) surface (air) temperature GMST; climate models indicate that many other changes in Earth's climate scale with change in GMST. The choice of GMST as the index of climate change together with recognition that Earth's energy content H is controlled by shortwave absorption and by longwave emission at the top of the atmosphere as dH/dt = γ J sub(S)/4 - ε σ T sub(s) super(4), where T sub(s) is GMST, γ is the planetary coalbedo (complement of the Bond albedo, ~0.70), J sub(S) is the solar constant (~1368 W m super(-2)), σ is the Stefan-Boltzmann constant, and ε defines an effective emissivity (~0.62) as the ratio of the longwave flux emitted at the top of the atmosphere to that emitted by a black body radiator at the global mean surface temperature, leads to the choice of reference no- feedback or "open loop" climate sensitivity S sub(0) as the equilibrium change in GMST that would result from a small change the planetary energy budget, forcing Δ F, normalized to that forcing, for γ and ε held constant. This definition yields to first order a climate sensitivity in the absence of feedbacks S sub(0) = (dT sub(s)/dΔ F) sub(0) = T sub(s)/γ sub(0JS), where the subscript 0 denotes absence of feedback. For T sub(s) = 288 K, S sub(0) = 0.30 K/(W m super(-2)); for forcing from doubled CO sub(2) taken as Δ F sub(2X) = 3.7 W m super(-2), the corresponding CO sub(2) doubling temperature change (interpreted as a derivative quantity) Δ T sub(2X0) = 1.1 K. This no-feedback sensitivity serves as the basis for considerations of feedbacks which would increase or diminish Earth's climate sensitivity from this no- feedback value. Formally this sensitivity is S = fS sub(0) = S sub(0)/(1-Φ ), where f is the feedback factor and where the total feedback strength is Φ = (d lnγ /d lnT sub(s)) sub(0)/4 - (d lnε /d lnT sub(s)) sub(0)/4; a positive value of Φ denotes positive feedback, an increase in the sensitivity over the no-feedback value. The two contributions to feedback strength denote changes in planetary coalbedo and effective emissivity with change in GMST. A decrease in cloudiness (increase in coalbedo) with increasing GMST would result in positive shortwave feedback (positive contribution to Φ ); similarly an increase in atmospheric water vapor content and associated longwave absorption with increasing GMST (decrease in emissivity) would result in positive longwave feedback. For climate sensitivity Δ T sub(2X) = 3 K (IPCC, 2007) the feedback factor 2.7 corresponds to feedback strength Φ = 0.63. Determining the contributions of individual climate processes to the feedback strength and the sensitivity of feedback to representations of these processes is a major challenge facing the climate modeling community.

AN - 68338083; 17873134 AB - UNLABELLEDThe methamphetamine molecule has a chiral center and exists as 2 enantiomers, d-methamphetamine (the more active enantiomer) and l-methamphetamine (the less active enantiomer). d-Methamphetamine is associated with more intense stimulant effects and higher abuse liability. The objective of this study was to measure the pharmacokinetics of d-methamphetamine for comparison with both l-methamphetamine and (-)-cocaine in the baboon brain and peripheral organs and to assess the saturability and pharmacologic specificity of binding.METHODSd- and l-methamphetamine and (-)-cocaine were labeled with (11)C via alkylation of the norprecursors with (11)C-methyl iodide using literature methods. Six different baboons were studied in 11 PET sessions at which 2 radiotracer injections were administered 2-3 h apart to determine the distribution and kinetics of (11)C-d-methamphetamine in brain and peripheral organs. Saturability and pharmacologic specificity were assessed using pretreatment with d-methamphetamine, methylphenidate, and tetrabenazine. (11)C-d-Methamphetamine pharmacokinetics were compared with (11)C-l-methamphetamine and (11)C-(-)-cocaine in both brain and peripheral organs in the same animal.RESULTS(11)C-d- and l-methamphetamine both showed high uptake and widespread distribution in the brain. Pharmacokinetics did not differ between enantiomers, and the cerebellum peaked earlier and cleared more quickly than the striatum for both. (11)C-d-Methamphetamine distribution volume ratio was not substantially affected by pretreatment with methamphetamine, methylphenidate, or tetrabenazine. Both enantiomers showed rapid, high uptake and clearance in the heart and lungs and slower uptake and clearance in the liver and kidneys. A comparison of (11)C-d-methamphetamine and (11)C-(-)-cocaine showed that (11)C-d-methamphetamine peaked later in the brain than did (11)C-(-)-cocaine and cleared more slowly. The 2 drugs showed similar behavior in all peripheral organs examined except the kidneys and pancreas, which showed higher uptake for (11)C-d-methamphetamine.CONCLUSIONBrain pharmacokinetics did not differ between d-and l-methamphetamine and thus cannot account for the more intense stimulant effects of d-methamphetamine. Lack of pharmacologic blockade by methamphetamine indicates that the PET image represents nonspecific binding, though the fact that methamphetamine is both a transporter substrate and an inhibitor may also play a role. A comparison of (11)C-d-methamphetamine and (11)C-(-)-cocaine in the same animal showed that the slower clearance of methamphetamine is likely to contribute to its previously reported longer-lasting stimulant effects relative to those of (-)-cocaine. High kidney uptake of d-methamphetamine or its labeled metabolites may account for the reported renal toxicity of d-methamphetamine in humans.

AN - 68181904; 17599397 AB - BACKGROUNDMethylphenidate (MP) and amphetamine, which are the mainstay for the treatment of ADHD, have raised concerns because of their reinforcing effects and the fear that their chronic use during childhood or adolescence could induce changes in the brain that could facilitate drug abuse in adulthood.METHODSHere we measured the effects of chronic treatment (8 months) with oral MP (1 or 2 mg/kg), which was initiated in periadolescent rats (postnatal day 30). Following this treatment, rats were tested on cocaine self-administration. In addition at 2 and 8 months of treatment we measured dopamine D2 receptor (D2R) availability in the striatum using [(11)C]raclopride microPET (microPET) imaging.RESULTSAnimals treated for 8 months with 2 mg/kg of MP showed significantly reduced rates of cocaine self-administration at adulthood than vehicle treated rats. D2R availability in the striatum was significantly lower in rats after 2 months of treatment with MP (1 and 2 mg/kg) but significantly higher after 8 months of MP treatment than in the vehicle treated rats. In vehicle treated rats D2R availability decreased with age whereas it increased in rats treated with MP. Because low D2R levels in the striatum are associated with a propensity for self-administration of drugs both in laboratory animals and in humans, this effect could underlie the lower rates of cocaine self-administration observed in the rats given 8 months of treatment with MP.CONCLUSIONSEight month treatment with oral MP beginning in adolescence decreased cocaine-self administration (1 mg/kg) during adulthood which could reflect the increases in D2R availability observed at this life stage since D2R increases are associated with reduced propensity for cocaine self administration. In contrast, two month treatment with MP started also at adolescence decreased D2R availability, which could raise concern that at this life stage short treatments could possibly increase vulnerability to drug abuse during adulthood. These findings indicate that MP effects on D2R expression in the striatum are sensitive not only to length of treatment but also to the developmental stage at which treatment is given. Future studies evaluating the effects of different lengths of treatment on drug self-administration are required to assess optimal duration of treatment regimes to minimize adverse effects on the propensity for drug self administration.

These probes include surface X-ray scattering and spectroscopy, scanning tunneling microscopy and optical second harmonic generation spectroscopy. Experimentally-determined inputs to the most advanced models include geometries of adsorbates, lattice parameters of mineral surface layers, electronic states of surface atoms and site-specific proton balances. This talk will include selections from this developmental history in order to discuss limitations of current experimentally-based conceptions of mineral-water interfaces. One critical limitation is imposed by the lack of a geometric description of the surface proton.

HMW1B has been subjected to extensive biochemical studies to date. However, direct examination of the structure of HMW1B has been lacking, leaving fundamental questions about the oligomeric state, the membrane-embedded {szligbeta}-barrel domain, the approximate size of the {szligbeta}-barrel pore, and the mechanism of translocator activity. In the current study, examination of purified HMW1B by size exclusion chromatography and negative staining electron microscopy revealed that the predominant species was a dimer. In the presence of lipid, purified HMW1B formed two-dimensional crystalline sheets. Examination of these crystals by cryo-electron microscopy allowed determination of a projection structure of HMW1B to 10 Aa resolution. The native HMW1B structure is a dimer of {szligbeta}-barrels, with each {szligbeta}-barrel measuring 40 Aa by 50 Aa in the two orthogonal directions and appearing largely occluded, leaving only a narrow pore. These observations suggest that HMW1B undergoes a large conformational change during translocation of the 125-kDa HMW1 adhesin.

Genes involved in resistance to the heavy metals Co(II), Cr(VI), Hg(II), and Ni(II) are concentrated in a 34-kb region on pMOL28, and genes involved in resistance to Ag(I), Cd(II), Co(II), Cu(II), Hg(II), Pb(II), and Zn(II) occur in a 132-kb region on pMOL30. We identified three putative genomic islands containing metal resistance operons flanked by mobile genetic elements, one on pMOL28 and two on pMOL30. Transcriptomic analysis using quantitative PCR and microarrays revealed metal-mediated up-regulation of 83 genes on pMOL28 and 143 genes on pMOL30 that coded for all known heavy metal resistance proteins, some new heavy metal resistance proteins (czcJ, mmrQ, and pbrU), membrane proteins, truncated transposases, conjugative transfer proteins, and many unknown proteins. Five genes on each plasmid were down-regulated; for one of them, chrI localized on pMOL28, the down-regulation occurred in the presence of five cations. We observed multiple cross-responses (induction of specific metal resistance by other metals), suggesting that the cellular defense of C. metallidurans against heavy metal stress involves various regulons and probably has multiple stages, including a more general response and a more metal-specific response.

While greenhouse gas forcing is relatively well known, aerosol forcing remains quite uncertain, with central value (1750-2005) of -1.2 W m super(-2) [range -0.6 to -2.4 W m super(-2), 5-95%; IPCC AR4, 2007; negative forcing denotes cooling influence]. Forward calculations of aerosol forcing are based on modeled aerosol loading and properties and/or from observed loadings of aerosols and correlations of aerosol loadings and cloud albedo. Alternatively aerosol forcing can be inferred by inverse calculations based on assumed climate sensitivity, measured change in GMST, and forcings other than by aerosols. Here I rely on recent empirical determination of Earths equilibrium climate sensitivity (Schwartz, 2007) as the quotient of climate system time constant [tau] and effective heat capacity C. [tau] is determined from autocorrelation of GMST over 1880-2004 as 5 +- 1 yr (uncertainties are 1-sigma estimates). Effective heat capacity is determined from change in global ocean heat content with increasing GMST over 1955- 2000, 14 +- 6 W yr m super(-2) K super(-1), equivalent to 110 m of ocean water; other sinks raise the effective planetary heat capacity C to 17 +- 7 W yr m super(-2) K super(-1). The resultant equilibrium climate sensitivity, 0.30 +- 0.14 K/(W m super(-2)), corresponds to an equilibrium temperature increase for doubled CO sub(2) of 1.1 +- 0.5 K, well lower than current IPCC estimates. The short time constant implies that GMST is in near equilibrium with applied forcings and hence that net climate forcing over the twentieth century can be obtained from the observed temperature increase over this period, 0.57 +- 0.08 K, as 1.9 +- 0.9 W m super(-2). For radiative forcing by incremental greenhouse gases, 2.2 +- 0.3 W m super(-2), other forcings over the twentieth century, mainly by incremental tropospheric aerosols, are inferred to be slight, -0.3 +- 1.0 W m super(-2). While the central value of this estimate is quite small, the range encompasses both fairly substantial negative forcing as well as possible positive forcing. These considerations emphasize the need for improved forward calculations of aerosol forcing to constrain estimates of climate sensitivity and to permit evaluation of climate models from their skill in reproducing temperature change over the twentieth century. --- Schwartz S.

AN - 20172591; 8328496 AB - Mexico City has a more concentrated set of emission sources than found in most, if not all, areas of the U.S., resulting in very high concentrations of gas phase pollutants. It is of interest to determine whether secondary organic aerosol (SOA) per unit precursor depends on absolute concentration. If it did, then the growth of megacities would lead to a different set of impacts compared to the situation where the same number of people and the same amount of industrial activity remain spread out over several smaller population centers. An expectation that SOA production might be greater in regions with high emissions can be justified on the basis of the absorptive/partitioning model, in which aerosol yields increase when there is a large amount of organics in the aerosol phase into which low volatility VOCs can partition. SOA production in Mexico City urban air masses is determined from the change in OA/CO as a function of photochemical age. Dilution is accounted for by normalizing results to CO, an urban tracer that is assumed to be emitted in proportion to SOA precursors. SOA production, so determined during the 2006 Milagro campaign, is compared with that determined in the eastern U.S. by ourselves and others during the 2002 and 2004 NEAQS campaigns. To provide a context for this comparison, we contrast chemical conditions in Mexico City with the NEAQS domain. Subject to several caveats, the Mexico City value for SOA per unit CO is similar to that found in the eastern U.S. JF - Proceedings of the American Geophysical Union 2007 Fall Meeting AU - Kleinman, L AU - Springston, S AU - Daum, P AU - Lee, Y AU - Nunnermacker, L AU - Senum, G AU - Wang, J AU - Weinstein-Lloyd, J AU - Alexander, M AU - Hubbe, J AU - Ortega, J AU - Canagaratna, M AU - Jayne, J Y1 - 2007/10// PY - 2007 DA - Oct 2007 KW - Pollution Abstracts; Meteorological & Geoastrophysical Abstracts KW - A21G-08 KW - Age KW - Atmospheric pollution models KW - Urban air KW - Mexico, Distrito Federal, Mexico City KW - American Geophysical Union KW - air masses KW - Tracers KW - Volatile organic compound emissions KW - Emissions KW - Industrial areas KW - Geophysics KW - uncertainty KW - Urban areas KW - Aerosols KW - Organic aerosols in atmosphere KW - USA KW - Photochemicals KW - Volatile organic compounds KW - M2 551.510.42:Air Pollution (551.510.42) KW - P 0000:AIR POLLUTION UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20172591?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/Pollution+Abstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.genre=book&rft.jtitle=&rft.atitle=&rft.au=Kleinman%2C+L%3BSpringston%2C+S%3BDaum%2C+P%3BLee%2C+Y%3BNunnermacker%2C+L%3BSenum%2C+G%3BWang%2C+J%3BWeinstein-Lloyd%2C+J%3BAlexander%2C+M%3BHubbe%2C+J%3BOrtega%2C+J%3BCanagaratna%2C+M%3BJayne%2C+J&rft.aulast=Kleinman&rft.aufirst=L&rft.date=2007-10-01&rft.volume=&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=Is+There+a+Megacity+Effect+on+SOA+Production%3F&rft.title=Is+There+a+Megacity+Effect+on+SOA+Production%3F&rft.issn=&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2008-07-01 N1 - Last updated - 2011-12-14 ER - TY - JOUR T1 - Widespread disruption in brain activation patterns to a working memory task during cocaine abstinence. AN - 68301031; 17765877 AB - Cocaine abstinence is associated with impaired performance in cognitive functions including attention, vigilance and executive function. Here we test the hypothesis that cognitive dysfunction during cocaine abstinence reflects in part impairment of cortical and subcortical regions modulated by dopamine. We used functional magnetic resonance imaging (fMRI) to study brain activation to a verbal working memory task in cocaine abusers (n=16) and healthy controls (n=16). Compared to controls, cocaine abusers showed: (1) hypoactivation in the mesencephalon, where dopamine neurons are located, as well as the thalamus, a brain region involved in arousal; (2) larger deactivation in dopamine projection regions (putamen, anterior cingulate, parahippocampal gyrus, and amygdala); and (3) hyperactivation in cortical regions involved with attention (prefrontal and parietal cortices), which probably reflects increased attention and control processes as compensatory mechanisms. Furthermore, the working memory load activation was lower in the prefrontal and parietal cortices in cocaine abusers when compared with controls, which might reflect limited network capacity. These abnormalities were accentuated in the cocaine abusers with positive urines for cocaine at time of study (as compared to cocaine abusers with negative urines) suggesting that the deficits may reflect in part early cocaine abstinence. These findings provide evidence of impaired function of regions involved with executive control, attention and vigilance in cocaine abusers. This widespread neurofunctional disruption is likely to underlie the cognitive deficits during early cocaine abstinence and to reflect involvement of dopamine as well as other neurotransmitters.

Mammalian homologs of YiiP play critical roles in zinc homeostasis and cell signaling. Here, we report the x-ray structure of YiiP in complex with zinc at 3.8 angstrom resolution. YiiP is a homodimer held together in a parallel orientation through four Zn super(2+) ions at the interface of the cytoplasmic domains, whereas the two transmembrane domains swing out to yield a Y-shaped structure. In each protomer, the cytoplasmic domain adopts a metallochaperone-like protein fold; the transmembrane domain features a bundle of six transmembrane helices and a tetrahedral Zn super(2+) binding site located in a cavity that is open to both the membrane outer leaflet and the periplasm.

AN - 70721234; 17582746 AB - Cocaine affects sensory perception and attention, but little is known about the neural substrates underlying these effects in the human brain. We used functional magnetic resonance imaging (fMRI) and a sustained visuospatial attention task to assess if the visual attention network is dysfunctional in cocaine abusers (n=14) compared to age-, gender-, and education-matched controls (n=14). Compared with controls, cocaine abusers showed (1) hypo-activation of the thalamus, which may reflect noradrenergic and/or dopaminergic deficits; (2) hyper-activation in occipital and prefrontal cortices, which may reflect increased visual cortical processing to compensate for inefficient visual thalamic processing; and (3) larger deactivation of parietal and frontal regions possibly to support the larger hemodynamic supply to the hyper-activated brain regions. These findings provide evidence of abnormalities in thalamo-cortical responses in cocaine abusers that are likely to contribute to the impairments in sensory processing and in attention. The development of therapies that diminish these thalamo-cortical deficits could improve the treatment of cocaine addiction.

AN - 70713250; 17630637 AB - This paper describes the activities that were involved with transferring, packaging, and shipping sixteen legacy fuel coupons and the unusual techniques employed. After remaining on the Brookhaven National Laboratory (BNL) Isotopes and Special Material (ISM) Group's inventory for several years, the fuel coupons were finally deemed waste in 2004. The fuel coupons were originally destined for the Hanford Site and were packaged according to Hanford's disposal criteria. After losing the Hanford Site disposal option shortly after packaging the coupons, the Savannah River Site (SRS) became the next option. The fuel coupons would be sent to SRS and stored in an underwater storage facility. This outlet required that the fuel coupons be repackaged and placed into a Shielded Inner Storage Can (SISC) for transfer into the SRS storage pool. Because the initial package had not been envisioned to require any repackaging, the resulting effort required many non-traditional techniques.

Within well-mixed boundary layers on four cloudy days, vertical profiles measured on board the Twin Otter show that dry aerosol size, volume concentration, and scattering coefficients all increased with increasing altitude, whereas the total number concentration remained essentially constant. A one-dimensional model, which uses simultaneous meteorological measurements as inputs, shows that the observed increase in aerosol volume concentration with increasing altitude is consistent with in- cloud sulfate production at the top of the boundary layer. The sulfate production rate was sufficiently fast to overcome the homogenization resulting from turbulent mixing. In contrast, on cloud-free days, measurements on a second aircraft show nearly uniform aerosol volume concentrations within well-mixed boundary layers. The observed vertical gradients in aerosol volume concentration suggest that even within well-mixed boundary layers, surface measurements may not be representative of aerosols properties (e.g., loading and scattering coefficients, etc.) at elevated altitudes, especially when SO sub(2) concentration and cloud coverage are high.

Gas hydrates can (a) be free floating in the sediment matrix, (b) contact, but do not cement, existing sediment grains, or (c) actually cement and stiffen the bulk sediment. Seismic surveys, often used to prospect for hydrates over a large area, can provide knowledge of the location of large hydrate concentrations because the hydrates within the sediment pores modify seismic properties. The ability to image a sample at the grain scale and to determine the porosity, permeability and seismic profile is of great interest since these parameters can help in determining the location of hydrates with certainty. We report here on an investigation of the structure of methane hydrate sediments at the grain-size scale using the synchrotron radiation-based computed microtomography (CMT) technique. Work has started on the measurements of the changes occurring as tetrahydrofuran hydrate, a surrogate for methane hydrate, is formed in the sediment.

Quantification methods were determined from test/retest studies, and sensitivity to pharmacological blockade was tested with different doses of atomoxetine (ATX), a drug that binds to the NET with high affinity (K sub(i)=2-5 nM). Methods: Twenty-four male subjects were divided into different groups for serial 90-min PET studies with [ super(11)C](S,S)-MRB to assess reproducibility and the effect of blocking with different doses of ATX (25, 50 and 100 mg, po). Region-of-interest uptake data and arterial plasma input were analyzed for the distribution volume (DV). Images were normalized to a template, and average parametric images for each group were formed. Results: [ super(11)C](S,S)-MRB uptake was highest in the thalamus (THL) and the midbrain (MBR) [containing the locus coeruleus (LC)] and lowest for the caudate nucleus (CDT). The CDT, a region with low NET, showed the smallest change on ATX treatment and was used as a reference region for the DV ratio (DVR). The baseline average DVR was 1.48 for both the THL and MBR with lower values for other regions [cerebellum (CB), 1.09; cingulate gyrus (CNG) 1.07]. However, more accurate information about relative densities came from the blocking studies. MBR exhibited greater blocking than THL, indicating a transporter density similar to 40% greater than THL. No relationship was found between DVR change and plasma ATX level. Although the higher dose tended to induce a greater decrease than the lower dose for MBR (average decrease for 25 mg=24 plus or minus 7%; 100 mg=31 plus or minus 11%), these differences were not significant. The different blocking between MBR (average decrease=28 plus or minus 10%) and THL (average decrease=17 plus or minus 10%) given the same baseline DVR indicates that the CDT is not a good measure for non-NET binding in both regions. Threshold analysis of the difference between the average baseline DV image and the average blocked image showed the expected NET distribution with the MBR (LC) and hypothalamus>THL>CNG and CB, as well as a significant change in the supplementary motor area. DVR reproducibility for the different brain regions was similar to 10%, but intersubject variability was large. Conclusions: The highest density of NETs was found in the MBR where the LC is located, followed by THL, whereas the lowest density was found in basal ganglia (lowest in CDT), consistent with the regional localization of NETs in the nonhuman primate brain. While all three doses of ATX were found to block most regions, no significant differences between doses were found for any region, although the average percent change across subjects of the MBR did correlate with ATX dose. The lack of a dose effect could reflect a low signal-to-noise ratio coupled with the possibility that a sufficient number of transporters were blocked at the lowest dose and further differences could not be detected. However, since the lowest (25 mg) dose is less than the therapeutic doses used in children for the treatment of attention-deficit/hyperactivity disorder ( similar to 1.0 mg/kg/day), this would suggest that there may be additional targets for ATX's therapeutic actions.

The C6 enzyme-linked immunosorbent assay, based on the IR6 region of VlsE, has become widely used in both the United States and Europe. We mapped the antigenic epitopes of IR6 to a shorter sequence that is equivalent in sensitivity and specificity to the full-length IR6 25-residue peptide. In addition, we observed significant differences in sensitivity between serum panels (60 to 100%), indicating that the selection of the serum panels can shape the apparent overall sensitivity of the assay. Contrary to prior reports, the assay sensitivity is greater when the IR6 peptide is derived from the sequence of the same infecting Borrelia genospecies. Using our North American panels and the two panels obtained from European Lyme disease patients, we determined that the IR6 assay that is based on a single genospecies of Borrelia spp. is not optimal for use as a universal diagnostic assay for Lyme disease.

On a newly modified 'drug' fluency task, individuals with cocaine use disorders who tested positive for cocaine at study day named more drug-related words than control subjects. The number of words provided on the classical semantic fluency task (animals and fruits/vegetables) did not differ between the groups. While the individuals with cocaine use disorders who tested negative for cocaine at study day did not differ from the control subjects in total words named on this task, a qualitative analysis indicated that both cocaine subgroups provided significantly more words pertaining to the experience of using drugs (paraphernalia, administration) than the matched control subjects. These results demonstrate that compared to classical neurocognitive assessment tools, newly tailored measures may be more sensitive to cocaine use disorders, psychopathologies that are often characterized by mild neuropsychological deficits but a well-circumscribed attentional bias to drug-related cues. Future studies are needed to probe the exact cognitive processes and neural circuitry underlying performance on this cue-sensitive 1-min measure.

Thus radiation regimes of proton exposure before HZE particle exposure simulate space radiation exposure, and measurement of the frequency of neoplastic transformation of human primary cells to anchorage-independent growth simulates an initial step in cancer induction. Although previous investigations indicated a synergistic increase in transformation yields in the cells exposed to protons followed by HZE particles, these experiments did not differentiate between the effect of splitting of the dose into two fractions and that of changing the ion beams. To test this, we irradiated cells with split doses of either protons or HZE particles, then measured clonogenic survival and neoplastic transformation, as measured by colony formation in semi-solid soft agar medium. The data show that the split dose of 20 cGy plus 20 cGy of either H or HZE ions gave about the same effect as the 40 cGy uninterrupted dose, quite different from the effect of the mixed ion beam H + HZE irradiation. We also asked if lower proton doses than 20 cGy followed 15 min later by 20 cGy of HZE ions gave greater than additive transformation frequencies. Substantial increases in transformation levels were observed for all proton doses tested, including 1 cGy. These results point to the signal importance of protons in affecting the effect of space radiation on human cells.

The samples, with lateral dimensions on the micrometer scale, were prepared on a silicon dioxide surface by direct exfoliation of crystalline graphite. The single-layer films were identified by using Raman spectroscopy. Topographic images of single-layer samples display the honeycomb structure expected for the full hexagonal symmetry of an isolated graphene monolayer. The absence of observable defects in the STM images is indicative of the high quality of these films. Crystals composed of a few layers of graphene also were examined. They exhibited dramatically different STM topography, displaying the reduced threefold symmetry characteristic of the surface of bulk graphite.

The further evolution of this effort involved the enlightened support of the Department of Energy (then AEC and ERDA) coupled with the lively interests of the archaeological, fine-arts and art-historical communities, their professional academics and the many graduate and undergraduate students who participated in the Brookhaven project. But more than new scientific methodologies, concepts and instrumentation were deployed. What developed was a large-scale, truly interdisciplinary effort, where scholars of the humanities and sciences worked side by side in a remarkable way, each led by the other, to the mutual benefit and increase of their knowledge and understanding. A paradigm of co-operation between arts and sciences was initiated: this paper presents a record of the process and its outcome, a novel blending of science and humanism that is very much taken for granted by research workers today.

Therefore, it remains unclear which brain region is relevant to the principal cognitive/behavioral function that is being studied, and which areas are activated either due to the additional cognitive function required to complete the task, or as a consequence of brain connectivity. The recent combination of transcranial magnetic stimulation (TMS) with fMRI holds promise for clarifying this dilemma. Using a pulse of magnetic field, TMS can non-invasively stimulate a specific brain region, thereby allowing brain activity to be manipulated as an independent variable, while, based upon the Blood Oxygenation Level Dependence (the BOLD effect), fMRI can evaluate the brain's response to this localized stimulus, highlighting the functional network directly associated with the stimulated site.

Although the terminal oxygenase from CHY-1 exhibits limited sequence similarity with well characterized RHDs from the naphthalene dioxygenase family, the crystal structure determined to 1.85 A by molecular replacement revealed the enzyme to share the same global alpha sub(3) beta sub(3) structural pattern. The catalytic domain distinguishes itself from other bacterial non-heme Rieske iron oxygenases by a substantially larger hydrophobic substrate binding pocket, the largest ever reported for this type of enzyme. While residues in the proximal region close to the mononuclear iron atom are conserved, the central region of the catalytic pocket is shaped mainly by the side chains of three amino acids, Phe350, Phe404 and Leu356, which contribute to the rather uniform trapezoidal shape of the pocket. Two flexible loops, LI and LII, exposed to the solvent seem to control the substrate access to the catalytic pocket and control the pocket length. Compared with other naphthalene dioxygenases residues Leu223 and Leu226, on loop LI, are moved towards the solvent, thus elongating the catalytic pocket by at least 2 A. An 11 A long water channel extends from the interface between the alpha and beta subunits to the catalytic site. The comparison of these structures with other known oxygenases suggests that the broad substrate specificity presented by the CHY-1 oxygenase is primarily due to the large size and particular topology of its catalytic pocket and provided the basis for the study of its reaction mechanism.

An Aerodyne aerosol mass spectrometer (AMS) was operated with a measurement cycle of 30 s, about an order of magnitude faster than used for ground-based measurements. Noise levels within a single measurement period were sub [mu]g m super(-3). Volume data derived from the AMS were compared with volume measurements from a Passive Cavity Aerosol Spectrometer (PCASP) optical particle detector and a Twin Scanning Electrical Mobility Spectrometer (TSEMS); calculated light scattering was compared with measured values from an integrating nephelometer. The median ratio for AMS/TSEMS volume was 1.25 (1.33 with an estimated refractory component); the median ratio for AMS/nephelometer scattering was 1.18. A dependence of the AMS collection efficiency on aerosol acidity was quantified by a comparison between AMS and PCASP volumes in two high sulfate plumes. For the entire field campaign, the average aerosol concentration was 11 [mu]g m super(-3). Compared with monitoring data from the IMPROVE network, the organic component made up a large fraction of total mass, varying from 70% in clean air to 40% in high concentration sulfate plumes. In combination with other optical and chemical measurements, the AMS gave information on secondary organic aerosol (SOA) production and the time evolution of aerosol light absorption. CO is taken as a conservative tracer of urban emissions and the ratios of organic aerosol and aerosol light absorption to CO examined as a function of photochemical age. Comparisons were made to ratios determined from surface measurements under conditions of minimal atmospheric processing. In air masses in which the NO sub(x) to NO sub(y) ratio has decreased to 10%, the ratio of organic aerosol to CO has quadrupled indicating that 75% of the organic aerosol is secondary. Also, the ratio of light absorption to CO has more than doubled, which is interpreted as an equivalent increase in the light absorption efficiency of black carbon due to aerosol ageing.

Allantoate amidohydrolase catalyzes the conversion of allantoate to (S)-ureidoglycolate, one of the crucial alternate steps in purine metabolism. The crystal structure of a ternary complex of allantoate amidohydrolase with its substrate allantoate and an allosteric effector, a sulfate ion, from Escherichia coli was determined to understand better the catalytic mechanism and substrate specificity. The 2.25 A resolution X-ray structure reveals an a/b scaffold akin to zinc exopeptidases of the peptidase M20 family and lacks the (b/a) sub(8)-barrel fold characteristic of the amidohydrolases. Arrangement of the substrate and the two co-catalytic zinc ions at the active site governs catalytic specificity for hydrolysis of N-carbamyl versus the peptide bond in exopeptidases. In its crystalline form, allantoate amidohydrolase adopts a relatively open conformation. However, structural analysis reveals the possibility of a significant movement of domains via rotation about two hinge regions upon allosteric effector and substrate binding resulting in a closed catalytically competent conformation by bringing the substrate allantoate closer to co-catalytic zinc ions. Two cis-prolyl peptide bonds found on either side of the dimerization domain in close proximity to the substrate and ligand-binding sites may be involved in protein folding and in preserving the integrity of the catalytic site.

This article presents the five most commonly used techniques, explains how each produces images, and describes how researchers interpret them. The authors give examples of key findings illustrating how each technique has extended and deepened our knowledge of the neurobiological bases of drug abuse and addiction, and they address potential clinical and therapeutic applications.

AN - 70305001; 17379090 AB - OBJECTIVENormal tissues, including the central nervous system, tolerate single exposures to narrow planes of synchrotron-generated x-rays (microplanar beams; microbeams) up to several hundred Gy. The repairs apparently involve the microvasculature and the glial system. We evaluate a hypothesis on the involvement of bystander effects in these repairs.METHODSConfluent cultures of bovine aortic endothelial cells were irradiated with three parallel 27-microm microbeams at 24 Gy. Rats' spinal cords were transaxially irradiated with a single microplanar beam, 270 microm thick, at 750 Gy; the dose distribution in tissue was calculated.RESULTSWithin 6 hours following irradiation of the cell culture the hit cells died, apparently by apoptosis, were lost, and the confluency was maintained. The spinal cord study revealed a loss of oligodendrocytes, astrocytes, and myelin in 2 weeks, but by 3 months repopulation and remyelination was nearly complete. Monte Carlo simulations showed that the microbeam dose fell from the peak's 80% to 20% in 9 microm.CONCLUSIONSIn both studies the repair processes could have involved "beneficial" bystander effects leading to tissue restoration, most likely through the release of growth factors, such as cytokines, and the initiation of cell-signaling cascades. In cell culture these events could have promoted fast disappearance of the hit cells and fast structural response of the surviving neighboring cells, while in the spinal cord study similar events could have been promoting angiogenesis to replace damaged capillary blood vessels, and proliferation, migration, and differentiation of the progenitor glial cells to produce new, mature, and functional glial cells.

Here, we show that, after transplantation into an animal model, neurons derived from mouse ES cells survived for over 32 weeks, maintained midbrain markers, and had sustained behavioral effects. Microdialysis in grafted animals showed that dopamine (DA) release was induced by depolarization and pharmacological stimulants. Positron emission tomography measured the expression of presynaptic dopamine transporters in the graft and also showed that the number of postsynaptic DA D sub(2) receptors was normalized in the host striatum. These data suggest that ES cell-derived neurons show DA release and reuptake and stimulate appropriate postsynaptic responses for long periods after implantation. This work supports continued interest in ES cells as a source of functional DA neurons. Disclosure of potential conflicts of interest is found at the end of this article.

AN - 69021647; 17236790 AB - Habituation enables the organism to attend selectively to novel stimuli by diminishing no-longer necessary responses to repeated stimuli. Because the prefrontal cortex (PFC) has a core role in monitoring attention and behavioral control especially under novelty, neural habituation responses may be modified in drug addiction, a psychopathology that entails PFC abnormalities in both structure and function. Sixteen cocaine abusers and 12 gender-, race-, education-, and intelligence-matched healthy control subjects performed an incentive sustained attention task twice, under novelty and after practice, during functional magnetic resonance imaging. For cocaine abusers practice effects were noted in the PFC (including anterior cingulate cortex/ventromedial rostral PFC, dorsolateral PFC, and medial frontal gyrus) and cerebellum (signal attenuations/decreases: return to baseline); activations in these regions were associated with craving, frequency of use, and length of abstinence. In the control subjects practice effects were instead restricted to posterior brain regions (precuneus and cuneus) (signal amplifications/increases: deactivation away from baseline). Also, only in the cocaine abusers, increased speed of behavioral performance between novelty to practice was associated with a respective attenuation of activation in the thalamus. Overall, we report for the first time a differential pattern of neural responses to repeated presentation of an incentive sustained attention task in cocaine addiction. Our results suggest a disruption in drug addiction of neural habituation to practice that possibly encompasses opponent anterior vs. posterior brain adaptation to the novelty of the experience: overly expeditious for the former but overly protracted for the latter. Overall, cocaine addicted individuals may be predisposed to an increased challenge when required to maintain alertness as a task progresses, not able to optimally utilize a prematurely habituating PFC to compensate with an increased attribution of salience to a desired reward.

Sulfur K-edge X-ray absorption near edge structure (XANES) spectroscopy provided information on the oxidation state and the mechanism of the incorporation of sulfur in FAs. During base flow delta (super 34) S values of groundwater sulfate were slightly depleted to those of recent atmospheric sulfate deposition with mean amount-weighted delta (super 34) S values of around +3ppm. The delta (super 18) O values of groundwater sulfate shifted to lower values compared to those of atmospheric deposition and indicated steadiness from base flow to peak flow. The reduced sulfur species (S (sub -1) /thiol; S (sub 0) /thiophene, disulfide, S (sub +2) /sulfoxide) of soil FAs averaged around 49% of the total sulfur and delta (super 34) S value in FAs was found to be 0.5ppm. The formation of polysulfides and thiols in FAs in concert with a decreasing isotope value of delta (super 34) S in FAs with respect to those of atmospheric deposition sulfate suggests oxidation of H (sub 2) S, enriched in the (super 32) S isotope, with organic material. The depletion of delta (super 18) O-SO (sub 4) (super 2-) by several per mil in groundwater sulfate with respect to those of atmospheric deposition is, therefore, consistent with the hypothesis that SO (sub 4) (super 2-) has been cycled through the organic S pool as well as that groundwater sulfate is formed by oxidation of H (sub 2) S with organic matter in the mineral soil of the catchment area.

Examination of invalid set generation by two representative advection schemes in one dimension for ensembles of 104 test cases spanning a range of initial moment sets and flow velocities reveals invalid set frequencies 0.7% for both schemes. Standard moment methods cannot accommodate invalid sets. Solutions to this problem are presented and evaluated for the ensembles and accurate moment advection free of invalid sets was obtained for both schemes. A new closure scheme insensitive to invalid sets using Lagrange interpolation of moment equation kernels is described and evaluated for condensation, dry deposition, and gravitational settling and found to match the high accuracy of quadrature.

Here we evaluated in cocaine addicted and healthy control participants the subjective sensitivity to reward gradients and its association with neural responses to sustained reward. A self-report questionnaire was used to assess the former. A functional magnetic resonance imaging task that utilized monetary reward as feedback in a blocked design was used to assess the latter. Results revealed that whereas control subjects valued high money more than low money, over half of the cocaine addicted subjects valued all monetary amounts equally. This compromised subjective sensitivity to gradients in reward value was significantly correlated with higher activations to money in the lateral orbitofrontal cortex/inferior frontal gyrus (BA 47) and amygdala, and lower activations in the middle frontal gyrus (BA 6), which together explained 85% of the variability on this rating scale in the cocaine abusers only. These results provide for the first time evidence of restricted subjective sensitivity to gradients of reward in cocaine addiction and of the involvement of frontolimbic brain regions (including the orbitofrontal cortex) in this deficit.

AN - 68951851; 17197102 AB - Our goal in the current report was to design a new functional magnetic resonance imaging (fMRI) task to probe the role of the anterior cingulate cortex (ACC) and orbitofrontal cortex (OFC) in processing of salient symptom-related cues during the simultaneous performance of an unrelated task in drug-addicted persons. We used a novel fMRI color-word drug Stroop task in 14 individuals with cocaine use disorders; subjects had to press for color of drug vs. matched neutral words. Although there were no accuracy or speed differences between the drug and neutral conditions in the current sample of subjects, drug words were more negatively valenced than the matched neutral words. Further, consistent with prior reports in individuals with other psychopathologies using different Stroop fMRI paradigms, our more classical color-word Stroop design revealed bilateral activations in the caudal-dorsal anterior cingulate cortex (cdACC) and hypoactivations in the rostro-ventral anterior cingulate cortex/medial orbitofrontal cortex (rACC/mOFC). A trend for larger rACC/mOFC hypoactivations to the drug than neutral words did not survive whole-brain corrections. Nevertheless, correlation analyses indicated that (1) the more the cdACC drug-related activation, the more negative the valence attributed to the drug words (r=-0.86, P<0.0001) but not neutral words; and (2) the more the rACC/mOFC hypoactivation to drug minus neutral words, the more the errors committed specifically to the drug minus neutral words (r=0.85, P<0.0001). Taken together, results suggest that this newly developed drug Stroop fMRI task may be a sensitive biobehavioral assay of the functions recruited for the regulation of responses to salient symptom-related stimuli in drug-addicted individuals.

We describe a novel radiosurgical approach using interlaced microplanar X-rays which we have termed "microradiosurgery." The use of microbeams allows for 1,000-times greater precision than current clinically employed techniques. As a demonstration of this new method, we produced a approximately 3.8 mm (3) lesion in the rat brain. The lesion was followed over a period of 216 days using 9.4 Tesla magnetic resonance imaging. Our results show a gradually developing lesion at the site of the interlaced beams. The lesion began as a high T2 signal only, but advanced to include a central area of low T1 and mixed T2 signal within 2 months. No lesion was observed in the other side of the brain which was exposed to non-interlaced microbeams only. Interlaced microbeams is an effective method to create focal brain microlesions. This technique may allow the future treatment of pathology not accessible by surgical or more traditional radiosurgical means.

Potassium- and Ba-birnessite, like Na-birnessite, were found to have triclinic symmetry. Rietveld analyses of the XRD patterns for K- and Ba-exchanged birnessite revealed decreases in the a, c, and beta unit-cell parameters, with a decrease of 1.7 and 0.5%, respectively, in unit-cell volume relative to Na-birnessite. Fourier electron difference syntheses revealed that the changes in the configuration of the interlayer species, and the charge, size, and hydration of the substituting cations, serve as the primary controls on changes in unit-cell parameters. Split electron density maxima with centers at (0 0 0.5) were present for Na, K, and Ba end-members; however, with increased substitution of K (super +) for Na (super +) , the axis connecting the split-site maxima rotated from an orientation parallel to the b-axis to along the a-axis. Substitution of Ba (super 2+) for Na (super +) did not result in rotation, but splitting of the interlayer site was more pronounced.

A 5-mm midventricular axial slice was sampled using a modified Look-Locker technique with 1.5 mm in-plane resolution, and 32 time points post-adiabatic inversion. The results confirmed that for most brain tissues, T1 values increased by more than a factor of 3 between 0.2T and 7T, and over this range were well fitted by T1 (s) = 0.583(B0)0.382, T1(s) = 0.857(B0)0.376, and T1(s) = 1.35(B0)0.340 for white matter (WM), internal GM, and blood 1H2O, respectively. The ventricular cerebrospinal fluid (CSF) 1H2O T1 value did not change with B0, and its average value (standard deviation (SD)) across subjects and magnetic fields was 4.3 (-0.2) s. The tissue 1/T1 values at each field were well correlated with the macromolecular mass fraction, and to a lesser extent tissue iron content. The field-dependent increases in 1H2O T1 values more than offset the well-known decrease in typical MRI contrast reagent (CR) relaxivity, and simulations predict that this leads to lower CR concentration detection thresholds with increased magnetic field.

AN - 68389886; 17202543 AB - OBJECTIVEThis study attempted to examine the brain's sensitivity to monetary rewards of different magnitudes in cocaine abusers and to study its association with motivation and self-control.METHODSixteen cocaine abusers and 13 matched healthy comparison subjects performed a forced-choice task under three monetary value conditions while brain activation was measured with functional magnetic resonance imaging. Objective measures of state motivation were assessed by reaction time and accuracy, and subjective measures were assessed by self-reports of task engagement. Measures of trait motivation and self-control were assessed with the Multidimensional Personality Questionnaire.RESULTSThe cocaine abusers demonstrated an overall reduced regional brain responsivity to differences between the monetary value conditions. Also, in comparison subjects but not in cocaine abusers, reward-induced improvements in performance were associated with self-reports of task engagement, and money-induced activations in the lateral prefrontal cortex were associated with parallel activations in the orbitofrontal cortex. For cocaine abusers, prefrontal cortex sensitivity to money was instead associated with motivation and self-control.CONCLUSIONSThese findings suggest that in cocaine addiction 1) activation of the corticolimbic reward circuit to gradations of money is altered; 2) the lack of a correlation between objective and subjective measures of state motivation may be indicative of disrupted perception of motivational drive, which could contribute to impairments in self-control; and 3) the lateral prefrontal cortex modulates trait motivation and deficits in self-control, and a possible underlying mechanism may encompass a breakdown in prefrontal-orbitofrontal cortical communication.

The severity of this other- directed violence (ODV) in the community may be influenced by insight into illness and adherence to psychotropic medications, however, few studies have tested these associations. Sixty male psychotic inpatients, legally detained at a forensic unit in New York City, were assessed with semi-structured interviews, supplemented with information from hospital and official records, family members and the treating clinician. Results indicated that in this unique sample of detained persons with psychotic disorders, (1) increase in the severity of community violence is associated with medication non-adherence, all dimensions of poor insight into illness, and several previously reported covariates such as substance use comorbidity, (2) no relationship was found between insight and adherence in this particular sample, (3) multivariate analyses showed that select covariates, along with medication adherence, and select insight domains predicted a total of 73% of the magnitude of ODV behavior in this sample. Overall, medication non- adherence explained a large amount of how violently participants behaved toward others. Since non-adherence was independent of poor insight, it may be more worthwhile for clinicians to develop treatment strategies to target medication adherence without directly addressing an elusive target such as insight into illness. Treatment addressing medication adherence needs to concomitantly target substance use behaviors since the latter was responsible for a substantial increase in ODV.

SWNTs were functionalized under ambient conditions with either the Knob protein domain from adenovirus serotype 12 (Ad 12 Knob) or its human cellular receptor, the CAR protein, via diimide-activated amidation. We confirmed the biological activity of Knob protein immobilized on the nanotube surfaces by using its labeled conjugate antibody and evaluated the activity and specificity of bound CAR on SWNTs, first, in the presence of fluorescently labeled Knob, which interacts specifically with CAR, and second, with a negative control protein, YieF, which is not recognized by biologically active CAR proteins. In addition, current-gate voltage (I- V sub(g)) measurements on a dozen nanotube devices explored the effect of protein binding on the intrinsic electronic properties of the SWNTs, and also demonstrated the devices' high sensitivity in detecting protein activity. All data showed that both Knob and CAR immobilized on SWNT surfaces fully retained their biological activities, suggesting that SWNT-CAR complexes can serve as biosensors for detecting environmental adenoviruses.

Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drag abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences.

Pfam has two large series of functionally uncharacterized families, known as Domains of Unknown Function (DUFs) and Uncharacterized Protein Families (UPFs). Results Crystal structures of two proteins from Deinococcus radiodurans and Streptomyces coelicolor belonging to Pfam protein family DUF178 (ID: PF02621) have been determined using Selenium-Single-wavelength Anomalous Dispersion (Se-SAD). Based on the structure, we have identified the putative function for this family of protein. Conclusion Unexpectedly, we found that DUF178 Pfam is remarkably similar to Pfam family DUF191 suggesting that the sequence-based classification alone may not be sufficient to classify proteins into Pfam families.

They are used in leak detection in underground storage and pipelines and in atmospheric transport and diffusion research on local, regional, and continental scales. They are likely to be a used globally for monitoring carbon sequestration in geological formations. The atmospheric background levels of these compounds must be accurately known, and trends in their concentrations determined for these compounds to be effective in monitoring CO sub(2) reservoirs and because there are environmental concerns about their release. Results of measurements of perfluorocarbon background concentrations from two recent field programs are presented, and trends in these values examined using data collected over the last 25 years. The current atmospheric concentrations of these compounds are in the low parts per quadrillion levels, and their annual atmospheric growth rate is less than 1 part per quadrillion per year. The environmental effects of these compounds are examined and found to be negligible at current release rates.

This paper highlights the approach of using emission inventories for attainment of demonstration challenges for the next generation of air quality management programs. It uses an integrated energy-emissions-economic decision making methodology of the MARKAL model, which is a well established state-of-the-art tool for energy systems analysis, developed at BNL in the 1970s. The flexible nature of the modeling framework allows comprehensive modeling of highly interconnected energy sub-systems, including energy resources, central and distributed electricity generation technologies, transmission and distribution technologies, end-use consumption technologies, all sectoral demands, related energy emissions and any constraints or policy assumptions that may be applied to the energy system. MARKAL analysis can be done for a short-, medium- or a long-term planning horizon.

AN - 68247639; 17165760 AB - Electrons and holes were injected selectively into poly-2,7-(9,9-dihexylfluorene) (pF) dissolved in a tetrahydrofuran (THF) and a 1,2-dichloroethane (DCE) solution, respectively, using pulse radiolysis. Transient absorption spectra of monoions of both signs revealed two bands attributable to formation of polarons, one in the visible region (pF+* at 580 nm, pF-* at 600 nm) and another in the near-IR region. Additional confirmation for the identification of pF+* and pF-* comes from bimolecular charge-transfer reactions, such as bithiophene-* + pF --> pF-* or pF+* + TTA --> +TTA+* (TTA = tri-p-tolylamine), in which known radical ions transfer charge to pF or from pF. Difference absorption spectra of pF chemically reduced by sodium in THF provided a ratio of absorbance of anions formed to bleaching of the neutral band at 380 nm. In conjunction with pulse-radiolysis results, the data show that each polaron occupies 4.5 +/- 0.5 fluorene units, most probably contiguous units. Extensive reduction of pF by sodium also revealed resistance to formation of bipolarons: excess electrons reside as separate polarons when two or more electrons were injected. Redox equilibria with pyrene and terthiophene by pulse radiolysis established reversible one-electron redox potentials of E0(pF+/0) = +0.66 V and E0(pF0/-) = -2.65 V vs Fc+/0. Together with the excited-state energy, these results predict a singlet exciton binding energy of 0.2 eV for pF in the presence of 0.1 M tetrabutylammonium tetrafluoroborate. This binding energy would increase substantially without an electrolyte.

The very wide range of olivine and low-Ca pyroxene compositions in comet Wild 2 requires a wide range of formation conditions, probably reflecting very different formation locations in the protoplanetary disk. The restricted compositional ranges of Fe-Ni sulfides, the wide range for silicates, and the absence of hydrous phases indicate that comet Wild 2 experienced little or no aqueous alteration. Less abundant Wild 2 materials include a refractory particle, whose presence appears to require radial transport in the early protoplanetary disk.

AN - 68128094; 17093073 AB - Cocaine abuse increases the risk of life-threatening neurological complications such as strokes and seizures. Although the vasoconstricting properties of cocaine underlie its cerebrovascular effects, the mechanisms underlying its neurotoxicity remain incompletely understood. Here, we use optical techniques to measure cerebral blood volume, hemoglobin oxygenation (S(t)O(2)), and intracellular calcium ([Ca(2+)](i)) to test the hypothesis that cocaine increases [Ca(2+)](i) in the brain. The effects of cocaine were compared with those of methylphenidate, which has similar catecholaminergic effects as cocaine (except for serotonin increases) but no local anesthetic properties, and of lidocaine, which has similar local anesthetic effects as cocaine but is devoid of catecholaminergic actions. To control for the hemodynamic effects of cocaine, we assessed the effects of cocaine in animals in which normal blood pressure was maintained by infusion of phenylephrine, and we also measured the effects of transient hypotension (mimicking that induced by cocaine). We show that cocaine induced significant increases ( approximately 10-15%) in [Ca(2+)](i) that were independent of its hemodynamic effects and of the anesthetic used (isofluorance or alpha-chloralose). Lidocaine but not methylphenidate also induced significant [Ca(2+)](i) increases ( approximately 10-13%). This indicates that cocaine at a dose within the range used by drug users significantly increases the [Ca(2+)](i) in the brain and its local anesthetic, but neither its catecholaminergic nor its hemodynamic actions, underlies this effect. Cocaine-induced [Ca(2+)](i) increases are likely to accentuate the neurotoxic effects from cocaine-induced vasoconstriction and to facilitate the occurrence of seizures from the catecholaminergic effects of cocaine. These findings support the use of calcium channel blockers as a strategy to minimize the neurotoxic effects of cocaine.

PCC 51142 has recently been sequenced and observed to contain 35 pentapeptide repeat proteins (PRPs). These proteins, while present throughout the prokaryotic and eukaryotic kingdoms, are most abundant in cyanobacteria. The sheer number of PRPs in cyanobacteria coupled with their predicted location in every cellular compartment argues for important, yet unknown, physiological and biochemical functions. To gain biochemical insights, the crystal structure for Rfr32, a 167-residue PRP with an N-terminal 29-residue signal peptide, was determined at 2.1 Aa resolution. The structure is dominated by 21 tandem pentapeptide repeats that fold into a right-handed quadrilateral beta -helix, or Rfr-fold, as observed for the tandem pentapeptide repeats in the only other PRP structure, the mycobacterial fluoroquinoline resistance protein MfpA from Mycobacterium tuberculosis. Sitting on top of the Rfr-fold are two short, antiparallel alpha -helices, bridged with a disulfide bond, that perhaps prevent edge-to-edge aggregation at the C terminus. Analysis of the main-chain ( Phi , zeta ) dihedral orientations for the pentapeptide repeats in Rfr32 and MfpA makes it possible to recognize the structural details for the two distinct types of four-residue turns adopted by the pentapeptide repeats in the Rfr-fold. These turns, labeled type II and type IV beta -turns, may be universal motifs that shape the Rfr-fold in all PRPs.

This is especially true of the U.S. Department of Energy (DOE) waste sites which hold a complex mixture of heavy metals, radionuclides, and organic solvents. In such environments enzymes that can remediate multiple pollutants are advantageous. We report here evolution of an enzyme, ChrR6 (formerly referred to as Y6), which shows a markedly enhanced capacity for remediating two of the most serious and prevalent DOE contaminants, chromate and uranyl. ChrR6 is a soluble enzyme and reduces chromate and uranyl intracellularly. Thus, the reduced product is at least partially sequestered and nucleated, minimizing the chances of reoxidation. Only one amino acid change, super(Tyr)128 super(Asn), was responsible for the observed improvement. We show here that ChrR6 makes Pseudomonas putida and Escherichia coli more efficient agents for bioremediation if the cellular permeability barrier to the metals is decreased.

We have tested the feasibility of using MRI in conjunction with quantitative image analysis to perform volumetric measurements of the brain in the developing human fetus in utero. The database comprises MR images of a total of 56 fetuses (gestational age 25-41 weeks) referred because of suspected abnormalities due to ultrasound findings, family history or maternal illness and scanned on a 1.5 T MR system using a single-shot fast spin echo (SSFSE) T2 sequence, slice thickness 3 mm, no gap. Four out of the 56 scans could not be used in the analysis due to poor image quality. Automatic segmentation (using NIH Image routines) was found to be unreliable in these fetal brains, so cerebral, cerebellar and ventricular regions were traced manually. Ventricular volumes did not vary with gestational age in normal fetuses (N = 27, R = 0.05, p = 0.8) while cerebral parenchyma and cerebellum volumes increased significantly during the same period (R = 0.67, p = 0.0002 and R = 0.51, p = 0.0066 respectively). Two calculated parameters: percent ventricular asymmetry and volume ratio of ventricles to hemispheric parenchyma were found to be very sensitive to ventricular pathology; such that the mean value of the latter in normal fetuses was 4.4% +/- 0.56 (mean +/- SEM, N = 27) compared to 34.3% +/- 17.6 (N = 6, p < 0.0001) in fetuses with ventriculomegaly. These results support the use of image analysis and MRI to produce normal growth curves as well as quantitative severity assessments of brain pathologies in the developing human fetus.

AN - 68904510; 17004800 AB - Density functional theory (DFT) was employed to investigate the behavior of Mo carbides in the water-gas-shift reaction (WGS, CO + H(2)O --> H(2) +CO(2)). The kinetics of the WGS reaction was studied on the surfaces of Mo-terminated Mo(2)C(001) (Mo-Mo(2)C), C-terminated Mo(2)C(001) (C-Mo(2)C), and Cu(111) as a known active catalyst. Our results show that the WGS activity decreases in a sequence: Cu > C-Mo(2)C > Mo-Mo(2)C. The slow kinetics on C-Mo(2)C and Mo-Mo(2)C is due to the fact that the C or Mo sites bond oxygen too strongly to allow the facile removal of this species. In fact, due to the strong O-Mo and O-C interactions, the carbide surfaces are likely to be covered by O produced from the H(2)O dissociation. It is shown that the O-covered Mo-terminated Mo(2)C(001) (O_Mo-Mo(2)C) surface displays the lowest WGS activity of all. With the Mo oxide in the surface, O_Mo-Mo(2)C is too inert to adsorb CO or to dissociate H(2)O. In contrast, the same amount of O on the C-Mo(2)C surface (O_C-Mo(2)C) does not lead to deactivation, but enhances the rate of the WGS reaction and makes this system even more active than Cu. The good behavior of O_C-Mo(2)C is attributed to the formation of a Mo oxycarbide in the surface. The C atoms destabilize O-poisoning by forming CO species, which shift away from the Mo hollow sites when the surface reacts with other adsorbates. In this way, the Mo sites are able to provide a moderate bond to the reaction intermediates. In addition, both C and O atoms are not spectators and directly participate in the WGS reaction.

It is difficult to understand such a complex system using macroscopic measurements, and chemical techniques that involve leaching or decomposition processes risk altering what may be very delicate states. Synchrotron techniques, however, offer a microscopic to molecular-scale view of intact, carefully-preserved samples. Element-specific X-ray absorption near-edge structure (XANES) spectroscopy provides information on oxidation state and chemical speciation. This can be used for trace elements such as uranium (down to several ppm concentration) as well as for major elements such as P, S, Fe, Mn and Ca. Specific examples will be shown, including uranium oxidation state at the L3 and M5 absorption edges, iron oxidation state, organic/inorganic sulfur speciation, and the identification of calcium, iron, and uranium phosphates using P XANES. More detailed local structural information (such as first- and second-neighbor distances and coordination numbers) can be obtained using extended X-ray absorption fine structure (EXAFS) spectroscopy, for elements at higher concentrations. Examples will include iron oxides and uranium phases. Semi-quantitative spatial distributions of elements can be imaged on the approximately 10-micron scale using synchrotron X-ray fluorescence microanalysis (SXRFMA). This is useful to identify mineral phases present in the sediment, and to determine with which of them the uranium may be associated. Microbeam XANES can then be employed to determine oxidation states etc. at spots of interest, and microbeam diffraction can identify crystalline materials. SXRFMA can also be employed in a microtomographic technique for 3-D structure.

Biogeochemical reactions (interaction with bacterial communities, mineral surfaces, and within pH/Eh gradients) will determine the ultimate fate of water-soluble nanoparticles (transport and persistence) and their ecotoxicity. This research aims to develop a molecular-level chemical understanding of the biogeochemical transformation in the natural environment of nanocrystals and nanoparticles functionalized with organic molecules to enhance their solubility in water. The hypothesis that guides this research is that nanoparticles interact with microorganisms present in soil and groundwater through passive and active mechanisms that alter the chemical form and hence the groundwater transport and soil retention characteristics of the nanoparticles, and ultimately the human exposure route and toxicity. Gold nanoparticles functionalized with citrate were studied for their mechanism of interaction with the soil microorganisms Pseudomonas fluorescens (aerobic) and Clostridium sp. (anaerobic). Changes in the nanoparticle surface chemical functionality and aggregation behavior in water were studied after exposure to growing and resting bacterial cells. Gold nanoparticle surface plasmon resonance, as measured by spectrophotometry, indicated modification of the citrate functionality and aggregation. Soft X-ray scanning transmission spectromicroscopy revealed that nanoparticles were attracted to the bacterial cell surface; nanoparticle-cell interactions were also studied by transmission electron microscopy. These batch studies were conducted in advance of column experiments to study advective-flow conditions and interactions with biofilms. The goal of these studies is to understand the predominant mechanisms of biotransformation in order to predict how such transformations will affect nanoparticle fate and transport in the environment.

The plume was determined to be approximately 4,200 feet long. The source of the plume was a 12-year-old leak in the reactor's spent fuel pool (SFP). This source of groundwater contamination was removed in December 1997 when the pool was drained. While plans were being developed to remediate the tritium plume, the Princeton Avenue Interim Remedial Action (IRA) was implemented at the leading edge of the plume to prevent it from migrating beyond Princeton Avenue. The IRA system went into operation in May 1997 and was transferred into a standby mode in September 2000 when it was demonstrated that the plume concentrations were lower than specific action levels specified in the Record of Decision. Groundwater model simulations forecasted that the tritium plume would radioactively decay and disperse in the aquifer to activities much less than drinking water standards before leaving the BNL site. The model projections also indicated that the plume leading edge would not grow significantly from the 1997 extent mapped as part of the Operable Unit III Remedial Investigation. Because of these projections and because there is no applicable treatment for environmental tritium concentrations, the primary means selected in the OU III Feasibility Study Report to remediate the tritium plume was natural attenuation with extensive monitoring and reporting, combined with limited groundwater extraction in response to specific contingencies. Since September 2000, several contingencies have been activated to manage the natural attenuation of the tritium plume on the BNL property. As of 2006 this strategy of plume management by natural attenuation has met all ROD requirements at minimal cost to BNL and to the satisfaction of all stakeholders JF - Abstracts with Programs - Geological Society of America AU - Burke, Thomas W AU - Hauptmann, Michael G AU - Anonymous Y1 - 2006/10// PY - 2006 DA - October 2006 SP - 198 PB - Geological Society of America (GSA), Boulder, CO VL - 38 IS - 7 SN - 0016-7592, 0016-7592 KW - United States KW - migration KW - monitoring KW - contaminant plumes KW - isotopes KW - Brookhaven National Laboratory KW - pollution KW - tritium KW - simulation KW - feasibility studies KW - remediation KW - ground water KW - aquifers KW - Suffolk County New York KW - models KW - attenuation KW - New York KW - radioactive isotopes KW - hydrogen KW - Upton New York KW - Long Island KW - water pollution KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/50615077?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Modeling+and+monitoring+basis+for+tritium+plume+management+strategies+at+Brookhaven+National+Laboratory&rft.au=Burke%2C+Thomas+W%3BHauptmann%2C+Michael+G%3BAnonymous&rft.aulast=Burke&rft.aufirst=Thomas&rft.date=2006-10-01&rft.volume=38&rft.issue=7&rft.spage=198&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2006 annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Investigation of the molecular level mechanism of the adsorptions is very important to predict the destiny of the adsorbed toxic cation and anions. Solid-state NMR spectroscopy was used to acquire information about surface and bulk hydroxyl groups, which play a role in immobilizing adsorbates, and to study ion sorption itself and the binding sites and the nature of binding of toxic cation and anions in soil minerals. In this study, (super 2) H, (super 6,7) Li, (super 133) Cs and (super 31) P MAS NMR spectroscopy were applied to study the local deuteron environments and the adsorption of lithium and phosphate as model ions on iron oxyhydroxides, lepidocrocite and goethite.

Aerosol components, including sea-salt- (sodium, chloride, magnesium, methansulfonate) and terrestrial/pollution-derived (ammonium, sulfate, nitrate, organics, potassium, and calcium) were measured using the particle-into-liquid sampler-ion chromatography technique and an Aerodyne AMS at a time resolution of 4 min and 30 s, respectively, both covering the size range of similar to 0.08 to 1.5 micrometers. The CCN spectrum was determined at a 1-s time resolution covering a supersaturation range between 0.02% and 1%. The accumulation mode particle size- number distribution was measured using a passive cavity aerosol spectrometer probe; the cloud droplet size-number distribution was determined using a Cloud Aerosol Probe. During the campaign sulfate/organic aerosols were always present, sea-salt aerosols were observed on half of the flights, and no dust or biomass burning contribution was noted as calcium and potassium were always below their limits-of-detection. Based on CCN spectra and cloud droplet number concentrations, the typical supersaturation of the marine stratus clouds was similar to 0.06%, corresponding to a CCN critical diameter between 0.1 and 0.2 micrometer. This large critical diameter makes the aerosol chemical composition measured appropriate for investigating the CCN properties and marine stratus clouds. We note that while sea-salt aerosols and sulfate aerosols were most likely externally mixed, the ensemble exhibits similar CCN properties irrespective of the relative mass concentrations of these two types of aerosols, owing partly to the similar activation properties of NaCl and (NH4)2SO4 aerosols, and that sea- salt particles were larger but fewer, accounting for a small fraction of cloud droplets. The organics did not appear to have significantly affected the CCN properties of the aerosols, suggesting that they were aged and soluble. Back trajectory calculations show that the time elapsed since their most recent land contact was always greater than 1 day.

However, many of these important findings have resulted from studies in vitro using postmortem tissues; as of now, these results have never been verified via in vivo methods because brain imaging of NET in living systems has been hampered due to the lack of suitable radioligands. The fact that all three monoamine (dopamine, norepinephrine, and serotonin) transporters (DAT, NET and SERT) are involved in various neurological and psychiatric diseases further emphasizes the need to develop suitable NET ligands so that researchers will be able to probe the contributions of each monoamine transporter system to specific CNS disorders. In this review article, the design and biological evaluation of several radioligands for imaging the brain NET system with PET are discussed. Based on these characterization studies, including C-11 labeled desipramine (DMI), 2- hydroxydesipramine (HDMI), talopram, talsupram, nisoxetine (Nis), oxaprotiline (Oxap), lortalamine (Lort) and C-11 and F-18 derivatives of reboxetine (RB), methylreboxetine (MRB) and their individual (R, R) and (S, S) enantiomers, in conjunction with studies with radiolabeled 4-iodo- tomoxetine and 2-iodo-nisoxetine, we have identified the superiority of (S, S)-[11C]MRB and the suitability of the MRB analogs as potential NET ligands for PET. In contrast, Nis, Oxap and Lort displayed high uptake in striatum (higher than thalamus). The use of these ligands is further limited by high non-specific binding and relatively low specific signal, as is characteristic of many earlier NET ligands. Thus, to our knowledge, (S, S)-[11C]MRB remains by far the most promising NET ligand for PET studies.

The derivation of number emission rates from inventory mass emission rates requires assumption of an average emitted particle size. Theoretical nucleation rates necessary to calculate ultrafine particle formation rates vary widely among mechanisms and parameterizations. With modal aerosol size representations, calculation of cloud condensation nucleus number concentration is typically based on accumulation mode number concentration (Nacc) and is thus sensitive to these uncertainties. In this study sensitivity studies were performed with a variety of approaches to NPF and several number emission rates, using the Community Multiscale Air Quality (CMAQ) regional-scale model over the continental U.S. with 60-km resolution for July 2004. As intermodal transfer from the Aitken to the accumulation mode (IMTR) is necessary in modal models to maintain distinct modes, and as transfer is not governed by a physical process, large NPF rates introduces a substantial uncertainty in accumulation mode number. Reducing the mean diameter of emitted particles by a factor of 2 (for fixed mass emission rate) for both the Aitken and accumulation modes gave a modest decrease in both NPF rate and IMTR but a substantial increase in Nacc. This results from increased surface area and reduced NPF when emitted mass is apportioned into smaller particles. When the NPF rate is large, the subsequent reduction of NPF rate due to limited H2SO4 was also large when using a 15-min time step. Nucleation and condensation are partially operator- split in CMAQ and when its binary nucleation rate (Vehkamaki et al., 2002) is replaced by the ternary rate (Napari et al., 2002), H2SO4 consumption is biased in favor of NPF. In the Aitken mode, average NPF and coagulation rates are nearly balanced. In the accumulation mode, number emissions and intermodal transfer are balanced by wet deposition.

The goal of this study was to extend previous reports indicating that rats will exhibit a positive conditioned place preference to inhaled toluene vapors and to determine the dose-response relationship for inhaled toluene in terms of exposure concentration and number of exposures. For the conditioned place preference experiments rats were exposed to toluene vapors at concentrations of 800, 2000, 3000 or 5000 ppm in one compartment of a three- compartment box. Results Following six conditioning sessions with toluene, a significant place preference was obtained at 2000 and 3000 ppm, but not at 800 or 5000 ppm. Extending the number of toluene pairings at the 2000 and 3000 ppm concentration to 12 significantly enhanced the place preference compared to that at six pairings. Conclusions These experiments extend our previous finding that rats will show a conditioned place preference to inhaled toluene, and indicate that a reinforcing "dose" of toluene depends on both the concentration and number of pairings.
