The behavior cannot be fully represented by a frequency-independent power-law model, as is commonly assumed. The lack of an accurate representation of P (sub n) and S (sub n) geometric spreading in a spherical Earth model impedes our ability to characterize Earth properties including anelasticity. We conduct numerical simulations to quantify P (sub n) and S (sub n) geometric spreading in a spherical Earth model with constant mantle-lid velocities. Based on our simulation results, we present new empirical P (sub n) and S (sub n) geometric-spreading models in the form G(r,f) = [10 (super n (sub 3) (f)) /r (sub 0) ](r (sub 0) /r) (super n (sub 1) (f)log(r (sub 0) /r)+n (sub 2) (f)) and n (sub i) (f) = n (sub i1) [log(f/f (sub 0) )] (super 2) +n (sub i2) log(f/f (sub 0) )+n (sub i3) , where i = 1, 2, or 3; r is epicentral distance; f is frequency; r (sub 0) = 1 km; and f (sub 0) = 1 Hz. We derive values of coefficients n (sub ij) by fitting the model to computed P (sub n) and S (sub n) amplitudes for a spherical Earth model having a 40-km-thick crust, generic values of P and S velocities, and a constant-velocity uppermost mantle. We apply the new spreading model to observed data in Eurasia to estimate average P (sub n) attenuation, obtaining more reasonable results compared to using a standard power-law model. Our new P (sub n) and S (sub n) geometric-spreading models provide generally applicable reference behavior for spherical Earth models with constant uppermost-mantle velocities.

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

Capillary electrophoresis coupled with ICP-MS (CE-ICP-MS) is a rapid and sensitive method to separate and detect metal species at trace-element concentrations. In this study CE-ICP-MS was used to measure partitioning of the rare earth elements (REE) between HS and a competing ligand (EDTA) under near environmental conditions (pH 6-10, 0.1 mol L (super -1) NaNO (sub 3) , 100 nmol L (super -1) REE, 10 mg L (super -1) HS). Conditional binding constants, K (sub c,LnHS) , were calculated for REE complexed with Elliot soil humic acid, Pahokee peat humic acid, Summit Hill soil humic acid, and Suwannee River natural organic matter and compared to existing data for REE complexation by Leonardite coal humic acid and Suwannee River fulvic acid. Results of these experiments show an increase in log K (sub c,LnHS) with decrease in ionic radius for REE-humic complexes (the lanthanide contraction effect), overall log K (sub c,LnHS) values ranging from 9 and 16 and indicating strong REE-HS binding, and a 2.7 log unit variation in K (sub c,LnHS) among humic sources. The inter-humic affinity for REE correlates with proton affinity and aromaticity of the HS sources.

The siderophore structure was characterized using 1D and 2D super(1)H, super(13)C and super(15)N NMR techniques (DQFCOSY, TOCSY, NOESY, HSQC and LR-HSQC) and was confirmed using ESI-MS and MS/MS experiments. The structural characterization revealed that the siderophore, rhodobactin, is a mixed ligand hexadentate siderophore with two catecholate and one hydroxamate moieties for iron chelation. We further investigated the effects of Fe concentrations on siderophore production and found that Fe limiting conditions (Fe concentrations from 0.1 mu M to 2.0 mu M) facilitated siderophore excretion. Our interests lie in the role that siderophores may have in binding metals at mixed contamination sites (containing metals/radionuclides and organics). Given the broad metabolic capacity of this microbe and its Fe scavenging ability, R. rhodochrous OFS may have a competitive advantage over other organisms employed in bioremediation.

Analysis of isotope labeling patterns requires knowledge of the fates of individual atoms and moieties in reactions, which can be difficult to collect in a useful form when considering a large number of enzymatic reactions. RESULTS: We report carbon-fate maps for 4605 enzyme-catalyzed reactions documented in the KEGG database. Every fate map has been manually checked for consistency with known reaction mechanisms. A map includes a standardized structure-based identifier for each reactant (namely, an InChI super(TM) string); indices for carbon atoms that are uniquely derived from the metabolite identifiers; structural data, including an identification of homotopic and prochiral carbon atoms; and a bijective map relating the corresponding carbon atoms in substrates and products. Fate maps are defined using the BioNetGen super(TM) language (BNGL), a formal model-specification language, which allows a set of maps to be automatically translated into isotopomer mass-balance equations. AVAILABILITY: The carbon-fate maps and software for visualizing the maps are freely available Supplementary information: Supplementary data are available at Bioinformatics online.

2, Effects of pre-existing structure AN - 51253882; 2008-062969 AB - The capture of vertically rising dikes by faults is examined with a combination of an analytic solution, numerical simulations and field observations. One of the numerical solutions and the field observations also provide insight into the intrusion of sills into the hanging wall of faults that are reactivated when lubricated by magma. The approximate analytic solution indicates that dike capture by a fault will be limited primarily to steeply-dipping faults. Capture will become easier, meaning that it will be possible for faults with shallower dips, as the intersection of the dike with the fault occurs at smaller depths. Capture will also be easier as it is harder for crack to grow in the hanging wall; this may be interpreted in terms of a higher tensile strength or in terms of shorter pre-existing cracks or higher fracture toughness. Numerical analysis using a discrete element code confirms this conclusion but also shows that the analytic solutions overestimate the difficulty of intruding a pre-existing fault, the maximum deviation occurring for faults dipping at 45 degrees . This finding that dike capture by faults should be restricted to high-angle faults and shallow depths is supported by field observations of exhumed Miocene basaltic volcanic terrain in central Nevada, USA. Differences in style seen in other regions are attributed to both the rock properties and the regional stress field. The numerical solutions also indicate that synintrusive fault slip is likely to lead to formation of sills in the hanging wall at depths of a few hundred meters or less: a finding that is also consistent with the field observations in Nevada.

Caldera formation was preceded by >10 Myr of volcanism dominated by intermediate composition rocks (57-70% SiO (sub 2) ) that contain components derived from the lithospheric mantle and Precambrian crust. Simple mixing between crust-dominated silicic melts and mantle-dominated mafic magmas, fractional crystallization, and assimilation accompanied by fractional crystallization are the principal mechanisms involved in the production of these intermediate lavas. A variety of isotopically distinct crustal sources were involved in magmatism between 13 and 6 Ma, but only one type (or two very similar types) of crust between 6 and 2 Ma. This long history constitutes a record of accommodation of mantle-derived magma in the crust by melting of country rock. The post-2 Ma Bandelier Tuff and associated rhyolites were, in contrast, generated by melting of hybridized crust in the form of buried, warm intrusive rocks associated with pre-6 Ma activity. Major shifts in the location, style and geochemical character of magmatism in the JMVF occur within a few million years after volcanic maxima and may correspond to pooling of magma at a new location in the crust following solidification of earlier magma chambers that acted as traps for basaltic replenishment.

Dauphine twinning is highly temperature sensitive, being initiated at a macroscopic differential stress of 50-100 MPa and, at 500 degrees C, saturates at 400 MPa. From normalized diffraction intensities the patterns of preferred orientation (or texture) can be inferred. They indicate a partial reversal of twinning during unloading. The remaining twins impose residual stresses corresponding to elastic strains of 300-400 microstrain. Progressive twinning on loading and reversal during unloading, and temperature dependence, can be reproduced with finite element model simulations.

As part of an initial hydrogeologic characterization to examine the impact of HE contamination, four boreholes were drilled into the vadose zone to depths between 38.1 and 63.3 m. The study objectives were to characterize contaminant nature and extent and to identify potential source areas and transport pathways. Besides providing an example of HE transport in the vadose zone, this study shows the value of integrating chloride and stable isotope tracer approaches with contaminant distribution information, and it provides insights on semiarid vadose zone behavior in the little studied, but widespread ponderosa pine forests of the American Southwest. Chloride-based vadose zone residence time estimates (1950-6080 yr) suggest that downward flow and transport over much of the mesa is limited. However, the presence of HE-contaminated transient saturated zones in two boreholes indicates that localized fast pathways also occur. Stable isotope data (delta (super 18) O and delta D) suggest that the source areas for contamination are former HE outfall discharge ponds that provide focused recharge to the transient saturated zones.

The prediction accuracy of any such model is critically dependent on the quality of the input parameters. Limited availability of (detailed) soil hydraulic data for large-scale hydroclimatic models (with grids ranging from several kilometers to several hundred kilometers) is a major challenge. To address this need, pedotransfer functions (PTFs) have been used to estimate the required soil hydraulic parameters from other available or easily measurable soil properties. While most previous studies derive and adopt these parameters at matching spatial scales (1:1) of input and output data, we have developed a methodology to derive soil water retention functions at the point or local scale using the PTFs trained with coarser scale input data. This study was a novel application of an artificial neural network (ANN)-based PTF scheme across two spatial support scales within the Rio Grande basin in New Mexico. The ANN was trained using soil texture and bulk density data from the SSURGO database (scale 1:24,000) and then used for predicting soil water contents at different pressure heads with point-scale data (1:1) inputs. The resulting outputs were corrected for bias before constructing the soil water characteristic curve using the van Genuchten equation. A hierarchical approach with training data derived from multiple clustered subwatersheds (with varying spatial extent) was used to study the effect of the increase in spatial extent. The results show good agreement between the soil water retention curves constructed from the ANN-based PTFs and field observations at the local scale near Las Cruces, NM. The robustness of the multiscale PTF methodology was further tested with a separate data set from the Little Washita watershed region in Oklahoma. Overall, ANN coupled with bias correction was found to be a suitable approach for deriving soil hydraulic parameters at a finer scale from soil physical properties at coarser scales and across different spatial extents. The approach could potentially be used for downscaling soil hydraulic properties.

These deposits contain potentially valuable paleoclimatic records. We report OSL ages for a section of unconsolidated Quaternary sediments exposed in the southwest part of Valle Toledo within Valles caldera. The sequence represents the transition over time from lacustrine to fluvial deposition at the site. We present a stratigraphically coherent depositional chronology for the Valle Toledo section consistent with the available radiocarbon constraint based on analysis of bootstrapped dose distributions derived from data collected by IRSL MAAD procedures. The ages suggest the existence of a late Pleistocene lake in Valle Toledo from at least 48.5 ka to approximately 44 ka, which is considerably younger than age interpretations based on correlation to a >500 ka rhyolite dam across San Antonio Creek. This study helps to emphasize the need for additional research to decipher the geologic history of the intra-caldera lakes as well as to correlate the records of climate and environmental change among the lacustrine deposits within Valles caldera.

Two tracer tests were performed using the Vadose Zone Research Park (VZRP) at the Idaho National Laboratory (INL). The first test occurred under quasi-steady-state conditions and the second was initiated in a much drier system and thus provided information regarding flow and transport under transient conditions. A one-dimensional analytical model was used to fit breakthrough curves resulting from the two tracer tests. The results of this modeling provide insight into the nature of flow in the fractured basalt, surficial alluvium, and sedimentary interbeds that comprise the vadose zone of the eastern Snake River Plain. Flow through the fractured basalt is focused and preferential in nature, and multiple flow paths arise due to numerous fractures functioning as transmissive pathways in addition to flow splitting along geologic contacts. Flow velocities were significantly higher during the test with the wetter flow domain, presumably due to increases in hydraulic conductivity associated with higher water contents of the geologic materials. Perching was observed above the alluvium-basalt contact and above the lower boundary of a locally continuous sedimentary interbed. The perching behavior between the two contacts was fundamentally different; the perched layer above the alluvium-basalt contact was neither laterally extensive nor temporally persistent in the absence of infiltration from the surface. In contrast, the perched layer along the interbed was significantly thicker and gave rise to lateral flow over distances on the order of hundreds of meters. Vertical transport is shown to occur predominantly through the main bulk of the sedimentary material of the interbed; lateral flow appears to occur primarily in the fractured basalt directly above the interbed.

Selection occurs via multispecies, stochastic population dynamics with reproduction probabilities that depend nonlinearly on the population densities of all species resident in the community. New species are introduced through mutation. Both models are amenable to exact linear stability analysis, and we compare the analytic results with large-scale kinetic Monte Carlo simulations, obtaining the population size as a function of an average interspecies interaction strength. Over time, the models self-optimize through mutation and selection to approximately maximize a community potential function, subject only to constraints internal to the particular model. If the interspecies interactions are randomly distributed on an interval including positive values, the system evolves toward self-sustaining, mutualistic communities. In contrast, for the predator-prey case the matrix of interactions is antisymmetric, and a nonzero population size must be sustained by an external resource. Time series of the diversity and population size for both models show approximate 1/f noise and power-law distributions for the lifetimes of communities and species. For the mutualistic model, these two lifetime distributions have the same exponent, while their exponents are different for the predator-prey model. The difference is probably due to greater resilience toward mass extinctions in the food-web like communities produced by the predator-prey model.

Using a Jacobian-free Newton-Krylov (JFNK) fully implicit solution method preconditioned with the SIMPLE (Numerical Heat Transfer and Fluid Flow. Hemisphere: New York, 1980) algorithm using centred discretization in space and three-level discretization in time converges with second-order accuracy for these problems. In the case of non-dimensional freezing, the temporal accuracy is sensitive to the choice of velocity attenuation parameter. By comparing to solutions with first-order backward Euler discretization in time, it is shown that the second-order accuracy in time is required to resolve the fine-scale convection structure during early gallium melting. Qualitative discrepancies develop over time for both the first-order temporal discretized simulation using the JFNK-SIMPLE algorithm that converges the nonlinearities and a SIMPLE-based algorithm that converges to a more common mass balance condition. The discrepancies in the JFNK-SIMPLE simulations using only first-order rather than second-order accurate temporal discretization for a given time step size appear to be offset in time.

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

These uncertainties include the amounts of Pu inhaled, the temporal exposure pattern of Pu air concentration, the particle-size distribution and solubility of the inhaled aerosols. To date, little individual and workplace-specific information has been used to assess these parameters for the Mayak workforce. However, extensive workplace-specific alpha activity air monitoring data set has been collated, which, if coupled with individual occupational histories, can potentially provide customised intake scenarios for individual Mayak workers. The most available Pu air concentration data are annual averages, which exist for over 100 defined work stations at radiochemical and chemical-metallurgical manufacturing facilities and basically for the whole period of Mayak production operations. Much sparser but more accurate data on Pu concentrations in workers' breathing zone are available for some major workplaces and occupations. The latter demonstrate that within a working shift, Pu concentrations varied over a range of several orders of magnitude depending on the nature of the operations performed. An approach to use the collated data set for individual intake reconstruction is formulated and its practical application is demonstrated. Initial results of ongoing experimental study on historic particle size at Mayak PA and their implications for intake estimation are presented.

Of the many particle properties that affect individualised dose estimates, particle solubility in lung fluids can be most important. This study compares in vitro dissolution rates of several plutonium industrial compounds present at different stages of the Mayak processing cycle using three different solvents. The results are then used to develop values of absorption parameters for individual dose assessments. In this study, the dissolution rates of nitrate, oxide and mixed plutonium aerosols were determined using a serum ultrafiltrate stimulant (SUF), phagolysosomal simulant fluid and Ringer's solution, all using a static system. According to the results obtained with SUF, Pu nitrate is absorbed into the blood to a larger extent than predicted using model parameters currently applied for Mayak workers. Absorption into the blood of 21.5 vs. 3% of deposited nuclide as current model predicts results in underestimation of systemic burden and overestimation of the lung dose. These data are being used to provide improved retrospective dose assessments for inhaled plutonium aerosols.

Since direct and diffuse radiation measurements include cloud effects, spring and summer dust and the variable summer monsoon rains, we concentrate in this paper on wintertime (November-February) aerosol optical depth measurements. The aerosol optical depth is derived from cloud-free turbidity measurements beginning in the 1960s and more recent sun photometer direct aerosol optical depth measurements. We compare the sun photometer derived trends with the pyranometer-derived trends using a radiative transfer model. These results are then compared to total ozone mapping spectrometer (TOMS) satellite-derived regional aerosol optical depths from 1980 to 2000. The results show that inclusion of the earlier turbidity measurements helps to establish an increasing regional turbidity trend. However, most of the increasing trend is confined to the larger cities in the Ganges River Basin of India (mainly Calcutta and New Delhi) with other cities showing a much less increase. Regional satellite data show that there is an increasing trend in aerosol off the coast of India and over the Ganges River Basin. The increase over the Ganges River Basin is consistent with population trends over the region during 1980-2000.

The analyses were obtained using an IR-laser coupled to a GC-IRMS interface. Ablation pits averaged 200 x 50 [mu]m, making it possible to sample individual or small bundles of osteons. Cortical bone is remodeled along osteons throughout a mammals life. Therefore, data at this scale can record seasonal variations in diet and drinking water during the adult stages of a mammal, whereas teeth provide may provide information about the juvenile years of a mammal. Average delta super(18)O and delta super(13)C values for the sheep from southwestern Ontario, Canada, were 14.0 and -16.1ppt, respectively. No trend was observed in the isotopic composition of the sheeps osteons, consistent with its constant diet and water supply. The delta super(18)O (14.2 to 16.6ppt) and delta super(13)C (-19.2 to -15.6ppt) values of osteons from White- Tailed deer from nearby Pinery Provincial Park, however, varied systematically and were negatively correlated. Oxygen isotope values of the osteons correlated well with changes in the delta super(18)O values of the main water source for these deer: winter average, -10.7ppt; summer average, -8.6ppt. The variation in delta super(13)C values of the osteons reflects changes in diet; summer diet consisted mainly of leafy C sub(3) vegetation (-28.4ppt), whereas winter diet comprised bark (-25.6ppt), C sub(4) grasses ( delta super(13)C, -12.7ppt), and corn stalks and husks (-11.3ppt).

In the fall of 2005, the group received an internal Los Alamos request to perform aerosol collection efficiency tests on two air samplers manufactured by the Bladewerx Corporation (Rio Rancho, NM). This paper presents the results from tests performed in the wind tunnel facility at a test velocity of 0.5 m s super(-1). The SabreAlert (Portable Workplace Monitor) and the SabreBZM (Breathing Zone Monitor) are both designed to detect and measure the presence of alpha emitting isotopes in atmospheres. The SabreAlert was operated at two test air flow rates of 6 and 45 liters per minute (LPM), and the SabreBZM was operated at two test air flow rates of 3 and 19 LPM. The aerosol collection efficiencies of both samplers were evaluated with oleic acid (monodisperse) liquid droplet aerosols tagged with sodium fluorescein tracer. These test aerosols varied in size from about 2.3 to 17.2 microns (aerodynamic equivalent diameter). The SabreAlert was roughly 100% efficient in aerosol collection at a flow rate of 6 LPM, and had an aerodynamic cutpoint diameter of 11.3 microns at the 45 LPM flow rate. The SabreBZM had an aerodynamic cutpoint diameter of 6.7 microns at the 3 LPM flow rate, but the SabreBZM aerosol collection efficiency never exceeded 13.6% at the 19 LPM test flow rate condition.

The system flexibility includes how it detects, captures, and processes event data. Custom data capture boards utilizing analog to digital converters (ADCs) and field programmable gate arrays (FPGA) detect events and capture correlated event data. A commercial DSP board processes the captured data and sends the results over the IEEE 1394 bus to the host computer that provides a user interface for acquisition, display, analysis, and storage. The system collects list mode data, correlated pulse shapes, or streaming data from a variety of detector types using Linux, Mac OS X, and Windows host computers. It extracts pulse features not found on commercial systems with excellent sensitivity and linearity over a wide dynamic range. List mode data are saved in FCS 3.0 formatted files while streaming or correlated waveform data are saved in custom format files for postprocessing. Open, reconfigurable cytometric acquisition system is compact, scaleable, flexible, and modular. Programmable feature extraction algorithms have exciting possibilities for both new and existing applications. The recent availability of a commercial data capture board will enable general availability of similar systems.

Comparable results were obtained from site-specific super(15)N-labeled WT-PLB embedded inside DOPC/DOPE (1,2-dioleoyl-sn-glycero-3-phosphocholine/1,2-dioleoyl-sn-glycero- 3 -phosphoethanolamine) mechanically oriented phospholipids' bilayers. The new NMR data support a pinwheel geometry of WT-PLB, but disagree with a bellflower structure in micelles, and indicate that the orientation of the cytoplasmic domain of the WT-PLB is similar to that reported for the monomeric AFA-PLB mutant.

7636638 AB - Numerous laboratory studies report carbon monoxide, hydrocarbon, and particulate matter emission reductions with a slight nitrogen oxides emission increase from engines operating with biodiesel and biodiesel blends as compared to using petroleum diesel. We conducted a field study on a fleet of school buses to evaluate the effects of biodiesel use on gaseous and particulate matter fuel-based emission factors under real-world conditions. The field experiment was carried out in two phases during winter 2004. In January (phase I), emissions from approximately 200 school buses operating on petroleum diesel were measured. Immediately after the end of the first phase measurement period, the buses were switched to a 20% biodiesel blend. Emission factors were measured again in March 2004 (phase II) and compared with the January emission factors. To measure gaseous emission factors we used a commercial gaseous remote sensor. Particulate matter emission factors were determined with a combination of the gaseous remote sensor, a Lidar (light detection and ranging), and transmissometer system developed at the Desert Research Institute of Reno, NV, U.S.A. Particulate matter emissions from school buses significantly increased (up to a factor of 1.8) after the switch from petroleum diesel to a 20% biodiesel blend. The fuel used during this campaign was provided by a local distributor and was independently analyzed at the end of the on-road experiment. The analysis found high concentrations of free glycerin and reduced flash points in the B100 parent fuel. Both measures indicate improper separation and processing of the biodiesel product during production. The biodiesel fuels used in the school buses were not in compliance with the U.S.A. ASTM D6751 biodiesel standard that was finalized in December of 2001. The U.S.A. National Biodiesel Board has formed a voluntary National Biodiesel Accreditation Program for producers and marketers of biodiesel to ensure product quality and compliance with the ASTM standard. The results of our study underline the importance of the program since potential emission benefits from biodiesel may be reduced or even reversed without appropriate fuel quality control on real-world fuels.

The consequential redistribution of water, radiation, and nutrient availability modified the ecosystem phenology, species composition, and forced the ecosystem to transition into a new state. We hypothesize that the hydrological processes in the ecosystem were also altered due to the mortality. Thus, our objective is to investigate changes in the soil-vegetation-atmosphere continuum across the plot, watershed, and ecoregion scales. The plot site is located near Los Alamos in Northern New Mexico (1.5 hectare), the watershed is the Rio Ojo Caliente Basin (1,050 km super(2)), a subbasin of the Upper Rio Grande, and the ecoregion consists of Pinus edulis, or pinon, across the Four Corners Region of Arizona, Colorado, New Mexico, and Utah (245,000 km super(2)). These sites are chosen because a significant portion of the woodland ecosystem (pinon-juniper) was affected during the mortality event. Examining a remotely-sensed vegetation index (1-km AVHRR NDVI from 1989 to 2007), there is an increasing trend in the NDVI from 1989 to 1998 (pre-drought period), a decreasing trend from 1999 to 2003 (drought period), and a dramatic increasing trend from 2004 to 2007 (post-drought period) in which the NDVI rebounds to nearly pre-drought magnitudes. This pattern exists across the three spatial scales and signifies a profound alteration in the ecosystem, for while the vegetation composition was altered to a great degree, the system rapidly recovered photosynthetically during the post-drought period. This may be attributable to the decrease in the less- responsive overstory (pinon mortality) and increase in the more-responsive understory (grasses and shrubs exploiting newly available resources). In order to examine hydrological changes, temporal patterns in gauge-based precipitation (frozen and unfrozen) and air temperature, and spatial-temporal patterns in PRISM precipitation, air temperature, and a soil moisture index are compared to the NDVI. The aim of this research is to explore the consequences of a severe drought married with elevated temperatures on vegetation and water resources. As the intensity and frequency of droughts are expected to increase in the southwestern U.S. with rising temperatures (IPCC 2007), this research contributes to our knowledge of ecosystem and hydrologic response to the changing climate.

While much of the significant body of international literature is accessible, many important works remain largely unknown or inaccessible. Some of the more difficult and essential documents to access are what is characterized as gray literature, which includes maps, databases, technical reports, graduate theses or dissertations, images, video, and government publications. Also, karst-related documents published in less-accessible languages are hard to access or find. The creation and implementation of the Karst Information Portal (KIP) beginning in 2005 addresses these and other information access and management problems by focusing on providing a global portal to provide a gateway to the Web for karst information and services. Digital versions of many karst resources will be available through KIP. Databases, datasets, bibliographies, images, gray literature, etc. that have been created world-wide by karst scientists, explorers, and educators will be accessible through KIP federated searching (i.e. simultaneous search of multiple data sources) identified karst sites on the Internet. In June 2007, an enhanced KIP was launched that includes The Guide to Speleological Literature database, a scanning electron micrograph repository, and links to key electronic karst resources. Like other well-known portals, such as Chronos, the KIP will continue to grow as users and developers bring more information within the network. We seek to expand KIP by developing partnerships to populate the portal with pertinent databases, maps, gray literature, and other information of interest to the geoscience community. Knowledge discovery, commenting by users, and collaborative workspaces (collaboratoria) are being tested through an image database of scanning electron micrographs in a joint project with Los Alamos National Laboratory. The KIP has the potential to transform geologic, biological, paleontological, archaeological, and historical research in karst by creating knew knowledge through the integration of international information in the discipline.

Scaling is related to heterogeneity in rock properties and the associated variability in local diffusion coefficients. But, it is also dependent on the ratio of the volume of open fractures to the wetted surface area, which varies at different scales ranging from aperture variations in single fractures to different fracture geometry within connected networks. To test concepts of scaling for problems ranging from bench-scale fractured-rock column experiments to fracture network characterization to kilometer-scale predictions, we have developed and implemented a novel generalized dual-porosity model (GDPM) within Los Alamos National Laboratory's FEHM groundwater flow and transport simulator. The GDPM formulation provides high numerical resolution in secondary matrix nodes near the primary fracture nodes, which decreases with distance away from the fractures, thus enabling highly efficient and accurate simulations of concentration fronts moving between the two continua without any limitations on the geometry or the reaction chemistry complexity. In this presentation, we first compare GDPM simulations with those achieved with analytical solution and particle tracking methods in the analysis of transport parameters for reactive and non-reactive solutes in column-scale studies. Then we evaluate upscaling methodologies for complex reactive processes that account for heterogeneity in diffusion coefficients, apertures, reactive minerals, and wetted surface area ratios first for single fractures with variable aperture distributions and then for networks involving multiple fractures. With the multiple scales considered in this study, we aim to derive field-scale model parameters for mass transfer coefficients, solute sorption to immobile minerals via both kinetic and equilibrium reactions, and solute reactions with colloidal particles. We have derived a transition probability method for upscaling individual parameters such as the matrix diffusion coefficient and are now extending the method to include multiple governing parameters such as fracture aperture and density.

Colorado's Piceance Basin alone contains approximately 500 billion barrels of recoverable shale oil, equivalent to half the world's proven oil reserves. It is conceivable that this region could eventually produce a quarter of the US daily demand, or up to 5 million barrels per day (Mmbbl/d). With the development of oil shale in the Piceance Basin, the Upper Colorado River and its tributaries would become an important source of water for operations. This talk aims to assess the potential impact of oil shale development on basin water resources, and in particular, the White River, CO. In-situ oil shale operations may require between 1 and 3 barrels of water per barrel of oil produced, including water requirements associated with power generation for in-situ heating processes, refining, retorting, cooling, dust control and reclamation. If water for industry related population growth is also counted then a 2.5 Mmbbl/d oil shale operation in the Green River basin (Wyoming, Utah, and Colorado) could require between 0.2 and 0.4 million acre feet per year (acre-ft/yr) of water 1,2,3. This is 3.5% to 8% of the 5.3 million acre-ft/yr 3 of water allocated to these Upper Colorado River States. This is based on average annual flows for the Colorado River and does not account for climate variability. We performed a water availability analysis for an oil shale production rate of 500,000 barrels per day (bbl/d) focused in the Piceance Basin. This analysis suggests that the White River should be able to support new water demands for oil shale if extractions from the river are limited to about 70,000 acre-ft/yr, and an additional 16,000 acre-ft of reservoir capacity is built in the river basin to accommodate drought. 1, Bartis, J.

However, this work and previous studies show that (super 14) C moving through a carbonate aquifer can experience significant retardation. In this study, batch experiments were conducted to help understand the mechanisms that control (super 14) C retardation, and improve reactive transport models. Groundwater (super 14) C is typically present as part of the bicarbonate anion, which tends not to sorb at naturally occurring groundwater pHs. Even in the absence of sorption, there are several processes that may retard (super 14) C. These include matrix diffusion, precipitation/dissolution, and isotopic exchange with aquifer carbonate minerals. Batch experiments using (super 14) C, high purity calcite, and dolomite were conducted to evaluate these processes. Minerals used in the experiments were analyzed via BET and SEM. The experimental variables included mineral saturation state, particle age, and particle size, all of which affected (super 14) C uptake. Experiments suggest that (super 14) C is very reactive with carbonate minerals, and that (super 14) C activity is lost via a non-equilibrium uptake process that cannot be described by an isotherm. A conceptual model of (super 14) C uptake that captures the non-equilibrium retardation behavior was developed, incorporating exchange/sorption, exchange/recrystallization, and solid-phase diffusion reactions. Carbon-14 uptake was modeled numerically using a continuous distribution of mass-transfer rate coefficients. The numerical model describes a process where the sorbent mineral surface is divided into compartments, and a unique reaction rate is applied to each, rather than treating the mineral surface as a homogeneous, single reaction rate mass sink. The set of reaction rates is calculated with a continuous gamma probability density function. Mass-transfer rates varied from relatively fast (10 (super -2) h (super -1) ) to very slow (10 (super -15) h (super -1) ), depending on the experimental variables.

Disposal of this water represents about 10% of the cost of hydrocarbon production. Inexpensive treatment technologies can lower the cost of disposal and also generate higher quality water for other uses. Surfactant-modified zeolite (SMZ) has been shown to effectively sorb a variety of nonpolar organic compounds from water. SMZ was tested as a medium to remove benzene, toluene, ethylbenzene, and xylenes (BTEX) from produced water generated during extraction of coal bed methane. BTEX removal is necessary prior to surface discharge of produced waters or as a pretreatment for reverse osmosis. We demonstrated in laboratory column experiments that BTEX-saturated SMZ is readily regenerated by air sparging. There was no loss in BTEX sorption capacity, and a minor decrease in the hydraulic conductivity of the SMZ, after 50 sorption/regeneration cycles. Based upon the laboratory results a pilot-scale produced-water treatment system was designed and tested at a reinjection facility in the San Juan Basin, New Mexico. The SMZ-based system was designed to treat up to 110 liters (30 gallons) of produced water per hour on a continuous basis by running two SMZ columns in parallel. The system performed as predicted based on laboratory results over repeated feed and regeneration cycles during the month-long operation. The BTEX-laden sparge gases were treated with a vapor-phase bioreactor system resulting in an emissions-free process.

Results of these experiments will be presented. Experiments are performed in a 30 cm long 6 mm inner diameter glass tube with tracer solutions of varying ionic strengths containing suspended microspheres and tritiated water, which is a conservative tracer. The first set of experiments is designed to examine the transport of microspheres of different sizes through the tube with conditions that minimize attachment and detachment, and therefore represent only the effects of dispersion. Subsequent experiments are replicas of the first with increasing ionic strengths, thus promoting attachment. The full experiment is repeated with the addition of packed glass bead media to the column. The microspheres chosen for this work are yellow-green carboxylate-modified latex in sizes of 0.2, 0.5, 1.0 and 2.0 microns. Samples are analyzed for tritium concentrations by Liquid Scintillation Analyzer (LSC) and microspheres are counted by Flow Cytometry. Data are presented as a dimensionless ratio of measured concentration to initial concentration (C/Co) varying with dimensionless pore volume (volume eluted/pore volumes). These data will give information about dispersion, attachment-detachment, and exclusion under simple and controlled conditions at a scale chosen to bridge the gap between microscopic scale experiments and bench-scale column experiments.

As one of the three largest Quaternary silicic calderas in North America, the Jemez has received great scrutiny by volcanologists. The Jemez Mountains is also a key locality where the plate-tectonic connection between seafloor spreading and isotopic age determination of the Jaramillo magnetic polarity chron was first established. Advances in (super 40) Ar/ (super 39) Ar isotopic-age determination have rendered old conventional K-Ar ages obsolete due to their imprecision and inaccurate young ages caused by incomplete degassing of sanidine. About 400 (super 40) Ar/ (super 39) Ar ages in the past two decades have been obtained on the rhyolites, dacites, andesites, basalts, and basanites of the Miocene to Quaternary Jemez volcanic field, and the interfingering Pliocene Cerros del Rio volcanic field to the east. In coordination with geologic mapping and hydrogeologic investigations of the Los Alamos-Espanola Basin area, a new synthesis of (super 40) Ar/ (super 39) Ar age determinations has been compiled. Individual (super 40) Ar/ (super 39) Ar age determinations may be highly precise, with relative analytical uncertainty as good as 0.1% for laser fusion analysis of sanidine. Yet the actual accuracy of age determination (for instance, relative to the Geomagnetic Polarity Time Scale) may be inadequately resolved due to the need to calculate ages relative to the age of a secondary monitor mineral. Ages reported for the commonly used monitors MMhb-1 hornblende (513.9 Ma-523.1 Ma) and Fish Canyon Tuff sanidine (27.57-28.27 Ma) vary as much as 2%, and (super 40) Ar/ (super 39) Ar data for the Jemez volcanic field have been published using this range of different monitor values. The argon geochronologic community has recently adopted a middle value of 28.02 Ma on Fish Canyon sanidine in order to consistently report data from labs using different internal standards. For the first time, we report on the (super 40) Ar/ (super 39) Ar geochronologic framework of the Jemez and Cerros del Rio volcanic field with all age determinations normalized to the same monitor value. New observations and interpretations on the timing and pattern of Jemez volcanism and its tectonic setting result from these recalculations.

Our data indicate activity along basin-margin faults early in rifting and that middle Miocene development of the Santa Clara Fault may possibly have allowed linkage of a central fault system (CFS) that accommodated rift inter-basinal strain in the late Miocene through Quaternary. The east-dipping Pajarito (PF), Santa Clara (SCF) and Black Mesa (BMF) faults divide the basin into a west-tilted, eastern half-graben and the structural bench of the Abiquiu embayment. East-down faulting along both basin margins occurred early in rift development (late Oligocene) and probably accompanied westward tilting and basanite-basaltic volcanism at 25-26 Ma. Some Laramide reverse faults were probably reactivated as extensional faults during late Oligocene time. A compressed stratigraphic section overlying an angular unconformity on the PF footwall indicates late Oligocene-Miocene movement along that structure. In the northeastern basin, comparison of stratal thicknesses and tilts parallel to and across structures suggests subsidence along faults and monoclines between 18 and 15 Ma. Good exposures east of Espanola show dips decreasing up-section, indicating west-tilting during mid-Miocene deposition. Stratal thickness differences between the footwall and hanging wall of the SCF become progressively more pronounced between 16 and 10 Ma, particularly after approximately 12.7 Ma, indicating increased throw rates on this fault. The significant post-12.7 Ma rate increase, plus stratigraphic evidence supporting 11-13 Ma movement along faults between the SCF and PF, may possibly have accompanied development of a linked central fault system (CFS) accommodating inter-basinal strain between the San Luis and Albuquerque Basins. The SCF produced approximately 430-500 m of stratigraphic separation after 10 Ma. The Pliocene-age Puye Fm is locally tilted 3-5 degrees W adjacent to east-down faults near the CFS; Pliocene strata further east are tilted 0-1 degrees W near Santa Fe. Local transverse folding in the immediate hanging-wall of the SCF may have begun in the late Miocene, but mostly developed in the latest Miocene through early Pliocene, and probably accompanied a component of lateral slip along the CFS.

Mex. is one of the Rio Grande rift's largest (>700 km (super 2) ) basaltic volcanic fields: it records the late-stage, volcano-tectonic evolution of the SW part of the Espanola Basin. The CdRVF reflects both regional proclivity toward Pliocene basaltic volcanism following protracted Neogene extensional tectonism and localized eruptive response to migration of basin- bounding faults. Approximately 180 km (super 3) of flat-lying basalt, andesite, and minor dacite lava flows and pyroclastic deposits of the CdRVF were erupted from > 50 exposed vents between 2.8Ma and 1.14 Ma. In the subsurface, volcanic deposits are interbedded with Santa Fe Group basin-fill sediment deposited in actively subsiding sub-basins of the southernmost Espanola Basin. Major basin-bounding faults in this area are characterized by predominantly N- and NW-trending, inward dipping faults having mostly dip-slip and subordinate strike-slip displacement. Although major basin-bounding structures were established prior to the onset of volcanism, protracted extension resulted in basinward migration of graben-bounding faults. In the area of the CdRVF, this resulted in a westward migration of active faulting. Phases of coeval volcanism at 2.8-2.6 Ma, 2.5-2.2 Ma, and 1.5-1.1Ma, were of decreasing eruptive volume and are delineated on the basis of mapped stratigraphy, argon geochronology, paleomagnetic and aeromagnetic properties, and records a simultaneous westward migration of eruptive centers. The alignment of vent areas with mapped or inferred faults strongly suggests deep magmatic conduits are utilizing local structures (faults and fractures, developed in response to regional stress). However, near-surface feeder dikes associated with eroded cinder cones record orientations that are not typically correlative with regional fault patterns suggesting near-surface conduits are independent of regional strain.

On the Atlantic continental shelf in New England, we estimate that up to 2800 cubic kilometers of freshwater are sequestered in Cretaceous, Tertiary, and Pleistocene sands below sea level. Scientific drilling during the 1970's revealed that TDS concentrations on the Atlantic continental shelf displays significant lateral variability. Off Long Island and New Jersey, for example, relatively low salinity groundwaters (less than 5000 ppm) extends over 150 km offshore. However, low salinity groundwater along the continental shelf off North Carolina, Georgia, and Florida are restricted to a few tens of km from the modern coastline at most. Two mechanisms have been proposed to explain the occurrence of offshore freshwater in New England: direct meteoric recharge from precipitation and ice sheet recharge beneath the Laurentide ice which extended as far south as Long Island. To study the Pleistocene hydrogeology of the continental shelf in New England, we have recently developed a new, parallel paleohydrogeologic model (PGEOFE) capable of representing Pleistocene sea level fluctuations, the waxing and waning of ice sheets, lithosphere flexure, permafrost generation, variable-density groundwater flow, heat, and solute transport. To honor the geology and morphology of the continental shelf, we have constructed a numerical model which extends from Maine to New Jersey using 5.8 million tetrahedral elements. To simulate millions of years of the hydrologic system, this parallel code was run on 256 processors using the NSF Teragrid Network. We found that sea level low stands were incapable of driving saltwater far offshore due to their low hydraulic gradients during sea level low stands. Ice sheet loading was a far more effective mechanism in driving freshwater seaward. However, this mechanism is limited to relatively short time periods (about 4000 years) when ice sheets overrun the continental shelf. We found that the presence of Hudson submarine canyons, a site where Pliocene sands crop out on the continental slope, plays and important role in focusing groundwater discharge during Pleistocene sea level low stands. This goes a long way towards explaining why New Jersey has so much freshwater so far offshore.

AN - 742774177; pmid-17902836 AB - alpha-plutonium's volume-corrected polycrystal elastic moduli were measured between 18 K and the upper limit of its occurrence, near 400 K. The two independent moduli for a polycrystal-bulk and shear-behave smoothly, indicating no phase transition. Both moduli show the same 50% increase on cooling, an order of magnitude larger than in other metals. The Debye temperature obtained from low-temperature elastic moduli, 207 K, significantly exceeds most previous estimates. The Gruneisen parameter gamma=5.3, obtained from the temperature dependence of the bulk modulus, is intermediate among previous estimates using other approaches, alpha-plutonium's Poisson ratio nu is low: 0.18, nearly temperature independent, and its small decrease on warming opposes usual behavior. The high gamma, large but equal bulk modulus and shear modulus fractional stiffening on cooling, and near-temperature-invariant nu are attributed to a single mechanism: 5-f electron localization-delocalization.

In contrast, most models of explosive flow in volcanic conduits either treat the multiphase mixture as a single fluid (pseudo-fluid approximation) and/or assume steady flow, thereby eliminating the potential for time-dependent effects related to multiphase dynamics. The 8 September 1977 explosive eruption of basaltic tephra through a geothermal borehole (Namafjall, Iceland) provides a unique test case for multiphase volcanic processes, given that its vertical extent ( approximately 1 km) is similar to that of natural volcanic conduits and its geometry is exactly known. We model this eruption by solving separate, time-dependent governing equations for conservation of mass, momentum, and energy of the gas and particle phases, allowing for drag and heat transfer between the phases. Model results are consistent with the development of transient waves of high particle concentration that propagate up the borehole, resulting in complex compressible flow phenomena along with ejection of particles in pulses in a manner that is consistent with observations at Namafjall. These transient processes occur even though the influx of gas and particles at the base of the borehole is treated as constant. Our results indicate that transient multiphase behavior is likely to be common in volcanic conduit flows, and that a key topic of future research is quantifying the types of time-dependent behaviors and their impacts on eruption column dynamics.

Estimates of local isostatic equilibration and potential energy, in tandem with lithosphere-related geoid anomalies, can be used to estimate paleolithospheric thickness, providing a clearer understanding of how and why continental topography is developed. We employ several simplifying assumptions about the crustal and mantle lithosphere density and structure (and readily acknowledge that our results are therefore first-order approximations) to predict the pre-orogenic structure of the lithosphere. At the outset we emphasize that while this approach does not provide an exhaustive evaluation of the deformation mechanism, it does serve to quantify the relative role played by the variations in the crustal and upper mantle components of the lithosphere. In this way we are able to use independent measurement of lithospheric geoid anomalies, current (post-orogenic) elevation and lithospheric structure, and paleoelevation information to estimate topographic development and structural support over time. Application of this technique to the southwestern United States indicates that the uplift of the Colorado Plateau is the result of processes in both the crust and mantle lithosphere and that the lithosphere of the pre-orogenic Southern Basin and Range was thinned relative to the Northern Basin and Range and Colorado Plateau. Although we use the southwestern U.S. as an example, this method can help constrain uplift mechanisms for any region for which the structure and geoid anomaly of the modern lithosphere is well understood.

Tools exist to automate workflow so that as the needs of the physics process model change (increased resolution through high gradients, decreased resolution to speed computations) the workflow can be streamlined and be independent of specific GFM format. GFMs, in which 3D space is divided into volumes bounded by surface, edges and vertices, are conceptually similar to engineering CAD models (planes, trains and automobiles). However, most GFMs do not have key features of CAD models. They do not have a full model description that includes information about geometry, topology and material properties. Most GFMs do not have an application programming interface (API) to perform geometric and topological queries. GFMs are often good sources for presentation graphics and support limited export capabilities. As a result, it is difficult to build a general mesh generation application that interacts with GFMs developed by different geologic modeling packages. Some of the differences between geologic and engineering set-up are highlighted based on examples from basin scale hydrology and fault system. Features that impact mesh design include: 1) discretization, 2) physics process model and 3) computational resources. These factors influence mesh design but workflow is still tightly tied to the underlying GFM. Next generation GFM tools can be enhanced by development more functional APIs and adoption of selected standards from engineering CAD. However, fundamental differences exist between engineering CAD and geologic models. The wholesale adoption of engineering standards will not solve some of the outstanding bottlenecks in the workflow interfacing 3D GFMs with physics process models. In the meantime, set-up workflow must be adapted to the GFMs available.

While most geologic framework models reflect the distribution of mapped geologic units or groups of units, the need sometimes exists for models of physical properties at a subunit scale to reflect the spatial variance of the properties within the unit. Often there are not sufficient direct geologic observations to accurately define the spatial variation of properties within units. Regional geophysical studies, conceptual models such as facies models, and/or stochastic methods may be used to define distribution of properties at this level of detail. Numerous tools are available to create geologic framework models and to provide 3-D visualizations of models of physical properties. These tools range from high-cost ($100K+) geologic modeling packages, to moderately-priced geologic information systems (GIS), to open-source visualization packages. A blend of such products have been used at Los Alamos National Laboratory to create a number of 3-D geologic framework models as well as visualizations of framework and physical properties models. Three-dimensional geologic framework models are presented for the Pajarito Plateau in New Mexico and Rainier Mesa in Nevada, illustrating strengths and weaknesses of some of the available software packages. A 3-D model of subsurface resistivity beneath the Pajarito Plateau may assist in the assignment of groundwater flow properties within units of the geologic framework model.

The Mortandad Canyon watershed encompasses 8.4 km2 (3.3 mi2) that drains eastwards across the Pajarito Plateau and crosses both LANL and San Ildefonso Pueblo land to its confluence with the Rio Grande. Research activities at LANL resulted in effluent discharges to Mortandad Canyon containing inorganic and organic chemicals and radionuclides. The Mortandad Canyon HFM was constructed using multiple types of field data to constrain the intricate stratigraphy that underlies the watershed. Bandelier Tuff from the Jemez volcanic field overlies interbedded Pliocene basalt and alluvial fan deposits and Miocene sedimentary deposits resulting in heterogeneous and discontinuous hydrostratigraphic units. These units control the migration of pore waters and dissolved contaminants through a thick (approx. 245-m) vadose zone. Multiple data integration and gridding techniques were utilized to render the 3D aquifer framework consisting of a shallow alluvial system, intermediate vadose zone containing localized perched ground water, and a deep regional aquifer. The HFM illustrates that the alluvial aquifer is a losing system due to preferential infiltration resulting in higher pore water contents extending downward towards two perched-intermediate ground water zones associated with dense basalt units. The HFM facilitated the calculation of contaminant mass inventories utilizing grids that represent the distribution of volumetric water content and associated contaminants (specifically nitrate and perchlorate). The mass inventories were within 15% of historic release estimates, indicating that the model accounts for the bulk of contaminant mass residing in the subsurface. The HFM is presently being used to convey the site conceptual models of pore water and contaminant distribution to LANL regulators and the general public, facilitating their participation in critical decisions about site characterization and remediation. Future HFM applications may include supporting risk-based modeling and remedial design evaluations.

Volcanological, geochemical, and time-volume characteristics of the Plio-Pleistocene part of the Southwestern Nevada volcanic field (SNVF) suggest it is an example of an extremely low volume-flux end member of basaltic volcanic fields. The SNVF has produced 17 volcanoes of dominantly trachybasaltic composition over the past 5 Myr with a total volume of slightly less than 6 km3. Eruptive volumes decreased between Pliocene- and Pleistocene-age volcanoes. Major element data suggest that most of the magmas underwent similar degrees of fractionation during ascent, and trace element compositions indicate a decrease in the degree of partial melting of the lithospheric mantle source since approximately 3 Ma. Isotopic data support an interpretation wherein magmas ascended relatively quickly from their source regions with little if any interaction with crustal rocks. Relationships between age and cumulative erupted volume indicate that the repose interval between eruptive episodes is determined by the volumes of prior episodes and, since approximately 3 Ma, an average eruption rate of approximately 0.5 km3/Myr, i.e., the field is time-predictable. All of these features support a model wherein magmatism is a passive result of regional tectonic strain. Partial melt resides in pockets of lithospheric mantle that are relatively enriched in hydrous minerals; slow deformation focuses melt, occasionally resulting in sufficiently high melt pressure to drive dikes upward and feed eruptive episodes. Larger source volumes result in larger eruptive volumes and wider dikes that relieve relatively more strain in the crust than smaller volume events, and therefore are followed by longer repose intervals required for recovery of crustal stresses. We suggest that time-predictability may be a fundamental property of tectonically controlled basaltic fields, where melt accumulation and ascent are controlled by tectonic strain rate. This behavior contrasts with magmatically controlled fields where magma flux is sufficiently high to overwhelm local tectonic strain, eruptions are primarily caused by magmatic processes that build pressure in reservoirs, and the systems are more likely to be volume-predictable.

Knowing this, several agencies undertook an investigation to evaluate flow paths and date the modern and submodern components of the groundwater-flow system at Los Alamos, New Mexico and the surrounding areas. At Los Alamos, groundwater is modern (post-1943), submodern (pre-1943), or mixed (containing both pre- and post-1943 components). The regional aquifer primarily consists of submodern groundwater. Mixed-age groundwater results from initial infiltration of surface water, followed by mixing with perched alluvial and intermediate-depth groundwater and the regional aquifer. No groundwater investigation is complete without using tritium/helium-3 and carbon-14 dating methods to quantify amounts of modern, mixed, and/or submodern components present in samples. Computer models of groundwater flow and transport at Los Alamos should be calibrated to groundwater ages for perched intermediate zones and the regional aquifer determined from this investigation. Results of this study clearly demonstrate the occurrence of multiple flow paths and groundwater ages occurring within the Sierra de los Valles, beneath the Pajarito Plateau, and at the White Rock Canyon springs. Localized groundwater recharge occurs within several canyons dissecting the Pajarito Plateau. Perched intermediate-depth groundwater and the regional aquifer beneath Pueblo Canyon, Los Alamos Canyon, Sandia Canyon, Mortandad Canyon, Pajarito Canyon, and Canon de Valle contain a modern component. This modern component consists of tritium, nitrate, perchlorate, chromate, boron, uranium, and/or high explosive compounds. It is very unlikely that there is only one transport or travel time, ranging from 25 to 62 years, for these conservative chemicals migrating from surface water to the regional water table. Lengths of groundwater flow paths vary within deep saturated zones containing variable concentrations of tritium. The 4-series springs discharging within White Rock Canyon contain a modern component of groundwater, primarily tritium. Average groundwater ages for the regional aquifer beneath the Pajarito Plateau vary from 565 to 10,817 years, based on unadjusted carbon-14 measurements.

The salient displays over 90 degrees of orogenic curvature, which appears related to a combination of primary thickness variations in the sedimentary wedge, differential shortening to maintain orogenic wedge taper, and interaction with Laramide foreland uplifts. Paleomagnetic data from the Triassic Ankareh Formation record systematic counter-clockwise rotations ( approximately 10 to 30 degrees ) in the northern part of the salient, with larger (up to 50 degrees ) rotations in frontal thrust sheets that interacted with the Gros Ventre foreland uplift, and variable ( approximately 10 to 40 degrees ) clockwise in the southern part of the salient that interacted with the Uinta Uplift. A strike test indicates an average of approximately 1/4 primary curvature and 3/4 secondary rotation to produce orogenic curvature, with additional complications near oblique ramps and transfer zones. Cleavage at high angles to bedding, minor folds, wedge faults, and cross striking veins in the Ankareh and Jurassic Twin Creek Formations record widespread early LPS and minor tangential extension parallel to structural trends. Principal shortening directions estimated from mesoscopic structures, strain, and AMS fabrics fan about the salient, remaining subperpendicular to structural trends, reflecting a combination of initial curvature and secondary rotation of LPS fabrics during thrusting. Strain analysis of deformed fossils and reduction spots indicates that internal shortening varies from generally <10% in frontal thrust sheets (but locally increases toward salient ends), to 20% in more interior sheets. Rotation and strain patterns, combined with offset of local piercing points, indicate that translation was overall eastward, with locally curved and partly fanned displacement trajectories toward the salient ends. A series of backbone cross sections around the salient indicate approximately 80 to 120 km of bulk shortening from major folds and faults in the Crawford, Absaroka, and Hogsback thrust systems (decreasing toward salient ends), with an additional approximately 10 to 30 km of internal shortening from strain. Work is underway to construct 3D restorations of swaths centered about the backbone sections, incorporating strain and rotation data.

A stepwise inverse method was developed to estimate the model parameters by coupling observation data from different sources and at various spatial scales ranging from single-well test, multiple-well pumping test to regional aquifer long-term monitoring data. To determine the flow parameters for these hydrofacies, we started from statistical analyses of outcrop permeability measurements and single-well slug or pumping test results to define the prior distributions of the parameters. This prior information was used to define the parameter initial values and the lower and upper bounds for inverse modeling. A number of inverse modeling scenarios were conducted including using drawdown data from the PM-2 and PM-4 pump tests separately, and a joint inversion coupling PM-2 and PM-4 pump test data, and head data from regional aquifer long-term monitoring which was started from the mid-1940s. Parameter sensitivity coefficients for different data sets were computed to analyze the parameter identifiability in different scenarios. Finally, the coupled inversion results offer a reasonable fitting to all data sets. The uncertainty of estimated parameters for the hydrofacies is addressed with the eigenvalues of covariance matrix and the parameter confidence intervals. The scale-dependence of permeability is discussed based on the influence ranges of the pumping tests and the spatial scales of the data sets.

New analyses include the 2004 transient Death Valley Regional (ground water) Flow System (DVRFS) model, the new hydrogeologic framework model (HFM), and the 2003 unsaturated zone (UZ) flow model. This model includes the following: (1) reflect the current understanding of SZ flow, (2) enhance model validation and uncertainty analyses, (3) improve locations and definitions of fault zones, (4) enhance grid resolution (500 m grid spacing to 250 m grid spacing), and (5) incorporate new data not used in the previous revision. The flow model was completed using the three dimensional, finite element heat and mass transfer computer code, FEHM V2.24. The SZ site scale flow model was calibrated with the commercial parameter estimation code, PEST to achieve a minimum difference between observed water levels and predicted water levels, and also between volumetric/mass flow rates along specific boundary segments predicted by the SZ regional scale and site scale models. 161 water level and head measurements having different weights were used for calibration. A comparison between measured water level data and the potentiometric surface yielded an RMSE of 20.7 m (weighted RMSE of 8.8 m). The calibrated model was used to evaluate the impact of alternative models on flow paths and specific discharge predicted by the model. Confidence in the results of the mathematical model was built by comparing: (1) calculated to observed hydraulic heads; and (2) calibrated to measured permeabilities and therefore specific discharge. In addition, it was confirmed that the flowpaths leaving the region of the repository are consistent with those inferred both from gradients of measured head and from independent water chemistry data. Uncertainties in the SZ site scale flow model were quantified because all uncertainty contributes to inaccuracy in system representation and response. Null space and solution space uncertainties were investigated and assessed.

The focus has been on the development of a single universal genetic operator for population evolution that is always efficient for a diverse set of optimization problems. However, existing theory and numerical experiments have demonstrated that it highly unlikely that such a universal operator exists. In this paper we show that significant advances in the field of evolutionary computation can be made if we embrace a concept of self-adaptive multimethod optimization, the goal of which is to develop a combination of search methods that have all the desirable properties to efficiently handle a wide variety of response surfaces. We present a new optimization algorithm, called AMALGAM-SO, that implements this new concept of multimethod search, and implements a restart strategy with successively increasing population size. Benchmark results in various dimensions, including real-world applications show that AMALGAM-SO is generally superior in efficiency, robustness and reliability to currently available search algorithms. The new search method is relatively easy to implement, and is designed to take full advantage of the power of distributed computer networks.

With increasing extension, the interaction between the faults results in a combined rotational and distortional strain field in which relay zones evolve. Existing models of relay zones do not address the three dimensional evolution of this complex strain field. Using a commercial finite element package ABAQUS, we have developed a three dimensional nonlinear numerical model to analyze the influence of (1) fault separation, (2) fault overlap/gap, (3) relative orientation of faults and, (4) material properties on the evolution of strain paths and fault interactions at various structural positions within the relay zone. The model uses simple fault geometries, isotropic material properties, displacement based boundary conditions and models the faults as frictional sliding surfaces. The model demonstrates that even under orthogonal extension and an overall plane strain deformation, the relay zone evolves in a three dimensional strain field along a non-coaxial strain path. The results suggest that the model derived maximum principal extension directions deviate from the regional extension direction within the relay zones. This deviation increases with a decreasing separation to overlap ratio between the normal faults. For a given value of the separation/overlap ratio, maximum deviation occurs at a structural level where the tip lines of the normal faults are closest. In addition, the sense of deflection (clockwise or counterclockwise) of the model derived principal strain and stress vectors from the imposed regional extension direction remains consistent at different structural positions in a synthetic relay zone. However in the case of an antithetic relay zone, this deflection sense changes in a systematic manner with the structural elevation. In general, in an antithetic relay zone, the sense of deflection of the principal strain and stress vectors changes across the structural elevation at which the tip lines of the normal faults are closest.

However, extensional processes have left the Colorado Plateau (CP) relatively undeformed, and it has emerged as a distinct tectonic province. New images of the lithosphere-scale structure constructed from the first complete deep seismic imaging transect of the CP in the "LA RISTRA" experiment show that CP crustal thickness exhibits highly variability (42-50 km) near its center and thins to 30-35 km thick at the edges, where the highest elevations are observed. Isostatic calculations constrained by these results show that only approximately 25% of central CP elevations can be explained by thickened crust alone, CP margins requiring nearly total mantle compensation. Travel-time body wave velocity inversions show a sharp, large magnitude contrast across the CP-Great Basin transition extending from the base of the crust to about 200 km depth. Also imaged is a fast seismic anomaly from 300 to 600 km depth beneath the NW portion of the model. Very slow P and S velocities beneath the Great Basin require the existence of partial melt and/or higher than average water content. We propose that the sharp contrast in mantle seismic properties across the western CP edge corresponds to differential lithospheric modification, during and subsequent to Farallon subduction and foundering across a boundary marking the western extent of unmodified Proterozoic mantle lithosphere. We interpret the deep fast anomaly as a remnant of thickened Farallon Plate and/or detached continental lithosphere that has sunk to transition zone depths. Shear-wave splitting observations suggest a system dominated by mantle flow around and deflected by a wedge-shaped lithospheric root beneath the CP.

The deposits of this lake were cored in May 2004 (GLAD5 project, hole VC-3) and 81 m of mostly lacustrine silty mud was recovered. A chronology has been established for VC-3 with a basal tephra Ar-Ar date of 552 + or - 3 kyr, and a detailed orbitally tuned record of organic carbon and other climate sensitive proxies of climate in the record. In this orbitally tuned record, glacial terminations V and VI correlate in time with other long Pleistocene records (marine SPECMAP, Lake Baikal) and two geomagnetic field polarity events in the core (14alpha and 11alpha ) correlate with globally recognized events. This record spans a critical interval of the middle Pleistocene from MIS 14 (552 kyr B.P.) to MIS 9 ( approximately 310 kyr B.P.), at which time the lacustrine sediments filled the available accommodation space in the caldera moat. Multiple analyses including core sedimentology and stratigraphy, sediment density and rock magnetic properties, organic carbon content and carbon isotopic ratios, C/N ratios, and pollen content reveal at least two glacial/interglacial cycles in the core (MIS 14 to MIS 9). Glacial terminations V and VI and interglacials MIS 13 and MIS 11 are captured at a high resolution. Both of these interglacials are relatively long compared with the intervening glacials, and interglacial MIS 13 is significantly muted in amplitude compared with MIS 11. Large amplitude hydrologic variability is evident in the interglacial MIS 11 section. Here, prominent wet-dry cycles with a approximately 11 ka duration are shown by correlative changes in sedimentology (laminated vs. mudcracked horizons) and in lake productivity (organic carbon). We hypothesize that this variability arises from a split-precessional cycle that modulates the strength of the southwest North American summer monsoon and hence summer rainfall amounts and lake levels during this extended interglacial period.

The system records paleoseismicity associated with Rio Grande Rift extension, with individual faults recording events as young as 2 ka. Both natural canyons and excavated trenches provide evidence that can be used to better understand the near-surface evolution of coseismic fault-zone structure and architecture. The main faults of the Pajarito system exhibit clay-rich fault cores surrounded by damage zones that are dominated by minor faults and fractures. Damage zone character varies with the degree of welding of the ash-flow tuff (ignimbrite) cooling units that constitute the Bandelier Tuff. Of particular interest are glassy non-welded units, which exhibit porosities of approximately 30-55%, and are locally so poorly lithified that they can be disaggregated by hand. These have been compared mechanically to poorly lithified sands. Recent work indicates that structures developed in such sands depend on strain rate: seismic strain rates result in the formation of deformation bands, whereas aseismic creep is recorded by grain alignment through distributed particulate flow. In glassy non-welded units of the Bandelier Tuff, damage zone structures are deformation bands, consistent with the documented history of seismicity. In contrast, many faults in older poorly lithified sediments of the Rio Grande Rift include both foliated zones formed through particulate flow, termed "mixed zones", and deformation bands. We hypothesize that the presence of mixed zones in these older fault zones may reflect a longer history that included episodes of aseismic creep.

It is characterized by sharp velocity transitions and underlies Colorado's highest topography. The CREST experiment involves: 1) mantle-scale seismic imaging using 60 3-D passive IRIS PASSCAL-supported stations (siting in 2007; installation in 2008) coordinated with 18 concurrent embedded EarthScope USArray stations; 2) geologic and thermochronologic studies of the uplift history of the Colorado Rockies; 3) studies of mantle to surface interconnections via mantle degassing, hydrochemistry, and neotectonics. Lowest mantle velocities coincide with the intersection of the NE-trending Proterozoic Colorado mineral belt and the NNW-trending extension of the Rio Grande Rift (Fig. 2), suggesting a geodynamic process in which Cenozoic and still-active asthenospheric upwelling and uplift are influenced by Proterozoic lithospheric heterogeneity. Time-space correlations between Cenozoic rock uplift and denudation patterns, magmatism, modern hydrothermal systems, and the modern-day mantle anomaly indicate that the Aspen anomaly may have been tectonically active at several times in the Cenozoic. Magmatism in central Colorado has been episodic, and includes Laramide volcanism of the Colorado mineral belt, Yellowstone-sized volumes of Oligocene volcanics near the anomaly (San Juan volcanic field) and 25-0 Ma basaltic magmatism at the edges of the anomaly. The highest peaks of the Colorado Rockies are located above the mantle anomaly and major drainage is radial away from the anomaly suggesting broad mantle-driven epeirogenic surface uplift. Apatite fission track data from the MWX well on the edge of the anomaly indicates the initiation of rapid exhumation at approximately 6 Ma, perhaps related to Neogene uplift. Mantle degassing and high heat flow through hot springs and CO2 springs indicate continued mantle devolatilization. Highest 3He/4He values are up to 2.17 Ra ( approximately 0.25 of MORB) at Poncha Pass at the north end of the Rio Grande rift, and mantle 3He/4He values ranging between 0.1 and 2.17 Ra are detected in almost all the hot springs in Colorado. Aqueous geochemical modeling indicate significant flux of mantle-derived CO2 (109 to 1010 mol C/yr). Emerging data offer potential for understanding ongoing mantle-to-surface interconnections.

The regional aquifer beneath the Pajarito Plateau contains background concentrations of total dissolved uranium ranging from 1.3 to 10.5 nanomolar (nM), and measurable dissolved oxygen (0.06 to 0.19 millimolar, mM), nitrate(N) (<0.11 mM) and sulfate (<0.07 mM). The regional aquifer varies from a calcium-sodium-bicarbonate to a sodium-calcium-bicarbonate solution with bicarbonate concentrations exceeding 1.1 mM. Uranyl carbonato complexes are predicted to dominate in groundwater. Concentrations of natural reductants including hydrogen sulfide and dissolved organic carbon are not sufficient to enhance stability of uranium(IV) complexes and solid phases. Background distributions of total dissolved uranium are believed to be controlled by chemical alteration of volcanic glass, specific adsorption of uranium(VI) complexes onto hydrous ferric oxide, and cation exchange of uranyl cation with calcium in smectite. The regional aquifer shows variable saturation with soddyite and is oversaturated with haiweeite depending on calcium and/or silica activity. Anthropogenic uranium has been released from laboratory outfalls to surface water since 1943. Surface water on the Pajarito Plateau provides recharge to alluvial and perched-intermediate depth groundwater and the regional aquifer. Elevated above-background concentrations of uranium (maximum of 50 nM) occur in the regional aquifer downgradient from Laboratory outfalls. Nitrate, perchlorate, and/or tritium coreleased with uranium(VI) have migrated to the regional aquifer at depths of 183 m or greater within 40 years since 1943. These chemicals are used to determine the source of uranium in addition to uranium isotopes. Laboratory uranium contamination in groundwater is limited to west of the Rio Grande. East of the Rio Grande between Santa Fe and Espanola, background concentrations of total dissolved uranium up to 7.6 micromolar have been detected. This area contains numerous volcanic glass deposits in various stages of alteration and roll-front uranium(VI) ore bodies.

The Espanola Basin is complexly faulted and includes a northwestern structural bench called the Abiquiu embayment (AE) and a west-tilted eastern half-graben, in whose western part lie three deep half-grabens adjoining a NNE-striking central fault system (CFS). Being an important contributory segment of the ancestral Rio Grande drainage, this basin contains evidence of five major depositional systems: 1) arkosic alluvial-slope sediments (AAS) on the hanging-wall ramp derived from the Sangre de Cristo Mts.; 2) volcanic-bearing alluvial fan deposits derived from the Jemez Mts.; 3) lithic to arkosic arenite associated with two southward flowing axial rivers on the basin floor; 4) south-flowing, volcanic-bearing alluvial-slope deposits in the AE; and 5) an eolian dune field in the northwest part of the basin. Correlation of distinctive lithofacies and abundant dated tephra allow basin-wide correlations that document the dynamics of these depositional systems. Between 28-25 Ma, the AAS prograded west during subsidence and probable tilting of the eastern half-graben. In the NE part of the basin, eastward migration of the basin-floor fluvial system during 18-16 Ma may be a response to localized, fault-related subsidence there. Between 16 and 6 Ma, the AAS progressively prograded west towards the CFS. Inferred linkage of these faults by the late Miocene led to erosion of the AE. Eolian sedimentation dominated the northwestern basin between 13.4-12 Ma, paradoxically a time of marked coarsening in the basin fluvial systems. Shortly afterwards (11-12 Ma), two rivers merged to form the ancestral Rio Grande. Between 12-9 Ma, the basin floor narrowed and briefly migrated 2.6 km onto the CFS footwall ca. 11 Ma. Late Miocene development of the Jemez volcanic field produced alluvial fans on the western flank of the basin. In the late Miocene through Pliocene, sediment preservation was greatest in the three deep half-grabens adjoining the CFS. Comparison of facies distributions and faults indicate that deposition was influenced by faulting. Invoking only tectonic controls, however, do not fully explain these distributions, so upland drainage evolution and climatic influences were also important.

Background values for groundwater are typically defined as constituent concentrations in waters directly upstream of a known source. These values are then compared to values directly downgradient of the source. In the case of the laboratory, however, the complex hydrogeology, natural variability of groundwater, geographic setting, and multiple historic releases make this background model impractical. Geographically the Laboratory is in the upward reaches of the Sierra de los Valles watershed which limits upgradient sampling locations of the regional aquifer. Groundwater in the regional aquifer beneath the Pajarito Plateau moves generally from northwest to southeast, where it discharges at or near the Rio Grande. Along the flow path the water interacts with rocks and mineral phases to produce more evolved water with relatively high total dissolved solids. Groundwater is also found in isolated but substantial perched water bodies in the vadose zone. Background must account for natural variability within the vadose zone and the regional aquifer. Potential background locations were selected based on length of sampling record, quality of well, consistency of sampling location for springs, and lack of impact from Laboratory activities. Locations were grouped using a cluster analysis and principal component analysis of geochemical constituents. The groups established through this statistical approach fit well with the current understanding of the groundwater flow system, which reflects groundwaters of varying ages, and displaying various degrees of rock/water interaction. The Pajarito Plateau background group consists of 29 locations. A suite of statistical values was calculated for perched intermediate groundwater and the regional aquifer which is now being used to screen analytical data to identify potential contamination. Monitoring data can be screened more appropriately based on association with a background characteristic of the Pajarito Plateau group. As additional background locations are identified over time, background may be refined using the same statistical approach.

This transitional basin comprises a main active segment between "platforms" that became stable after the initial phases of rifting in the Miocene. We will focus on the Albuquerque Basin transition. The SAGE Geophysical Field Course has access to over 200 km of seismic reflection profiles and some borehole data in the southern Espanola Basin that were acquired for petroleum exploration in the 1970's. These data have been a valuable supplement to the geophysical data gathered by SAGE in its 25 years of operation in the area. The interpretation has been integrated with the recent geophysical and geologic investigations by the U.S. Geological Survey and NM Bureau of Geology in the area. Several previously unappreciated results have been obtained from these data. The SW margin of the Laramide Sangre de Cristo/Brazos Uplift has been mapped in the subsurface adjacent to a complete pre-Tertiary section. A fault zone, controlling deposition of Oligocene volcanic rocks, has been identified on the eastern side of the basin extending from the Tijeras-Canoncito fault zone in the south, underneath western Santa Fe to where it connects to better exposed faults to the north. The western-most fault in this zone is the 35km long San Isidro Crossing Fault. The fault zone is always associated with changes in dip of the basin floor, and may have pre-rift ancestry. The Eocene Galisteo Basin has been mapped from its northern and eastern margins, thickening to the south. Uplift associated with rift extension in the northern Albuquerque Basin to the west has folded all pre-rift units about a N-S axis in the platform area. The transfer of extension from the Albuquerque Basin to the Espanola Basin terminates the folding in a hinge zone and develops the Espanola Rift basin to the north. The hinge zone roughly coincides with the thinning of the pre-Tertiary sediments on the Laramide Uplift. We now view the Espanola Basin as a composite expression of both Laramide and rift elements.

The speed with which these models can be built depends upon the set of available software tools, the complexity of the geology to be modeled, and the programming and/or scripting abilities that the model maker possesses. Geologic scenarios of multiple faults and complex folding may require piecewise building of a composite model. Proper models for depositional geometries of units may benefit from specific surface interpolation tools. Generally, the modeler can augment scattered "exact" data such as contact information from outcrops or drill holes, with conceptual data controls to enforce a reasonable model from the tools at hand. The 3-D geologic model which comprises the hydrogeologic framework model for the Pajarito Plateau in northern New Mexico was created using the ArcInfo GIS. The model spans four geologic quadrangles and is comprised of 28 geologic units and subunits that reflect the complex structural and depositional history of the sedimentary and volcanic rocks in this region of the Rio Grande Rift system. This model is presently used in groundwater flow and contaminant transport studies at Los Alamos National Laboratory. The techniques used to transfer geologic information into a usable framework model are varied and can be complex. The global availability of digital elevation model (DEM) data allows two-dimensional measurements of "hard" contact locations from outcrop mapping, well logging, and/or cross-sections, to be processed into sets of contact surfaces which fully define the geologic volumes of the model extent with high-fidelity at the control points. The true accuracy of the model can be enhanced by the judicious application of conceptual contours, developed from geologic intuition and "soft" constraints such as geophysical measurements, or the recorded absence of units within a drill hole.

Traditional graphical methods of classification typically use only major ions, while the multivariate statistical methods can include trace metal data and other geochemical parameters such as pH. This provides a more complete evaluation of water quality facies. The cluster analysis is a neutral approach to delineation of facies, without the bias of preconceived notions such as flow paths, anthropogenic inputs, or geographical features. From this, a picture of natural, or background, water quality can be extracted. The conceptual model of regional ground water is based on multiple chemistry, numerical modeling, and physical hydrogeologic studies. Regional ground water infiltrates in the Jemez Mountains in the west and Sangre de Cristo Mountains in the east, converging and discharging at the Rio Grande, with a concurrent increase in total dissolved solids and metals with residence time. Different ground water facies exist within this flow regime and the geochemistry is controlled by host rock interactions and altered by dilution and mixing with surface water and alluvial or intermediate depth waters. In addition, 50 years of human residence and industrial activity has added chemical signatures to some areas. PCA and CA methods were used to extract different water groupings or facies and the associated natural background water chemistry from these complicating factors. Water supply wells, monitoring wells, and local springs supplied data on inorganic constituents from 2000-present. Three statistically distinct ground water groups were found. Waters sampled from near the Rio Grande showed higher TDS and levels of some metals, likely indicating older, more evolved regional ground water. Waters from the western Pajarito Plateau showed lower TDS and metals, indicating a less evolved facies, while water sampled from the central Plateau showed intermediate TDS and metals and is likely indicative of mixed waters.

This model has evolved significantly since its initial development as a groundwater flow model for the entire 6,000 km (super 2) Espanola Basin. The original basin model was developed in 1998 in order to simulate groundwater flow along the major basins of the Rio Grande Rift. The U.S. Geological Survey and other researchers contributed to the effort of defining the initial conceptual model and provided the supporting datasets. Numerous papers have been presented and published in the past nine years documenting the evolution of this model. This presentation describes the latest developments with the LRGM, including: the development of new boundary conditions including a new infiltration map that is used for recharge; model calibration; and analyses of flow paths by forward and reverse particle tracking using geochemical tracer data. Although there is a thick unsaturated zone above the regional aquifer, the infiltration map is applied as a recharge map directly to the water table. Model calibration uses multi-scale datasets and is the subject of a companion paper in this conference (Dai et al., Session T27). Flow path analyses indicate that flow paths to Los Alamos water supply wells rarely originate at the water table, but rather, originate in deeper groundwaters at the western boundary of the model due to extreme stratigraphic anisotropy. However, there are some flow paths from the water table to deep water supply well screens indicating the existence of a vertical component of flow. LANL has been an active participant in the Espanola Basin Technical Advisory Group (EBTAG), and continues to work with collaborators from other agencies to ensure consistency and defensibility in groundwater modeling approaches. Future work planned for the LRGM includes the extension of the regional model boundaries using the latest geological data to include the Buckman well-field, an important water supply source for the city of Santa Fe, New Mexico. The extension of the model boundaries will be conducted in collaboration with EBTAG members in order to evaluate the potential impact of LANL activities on water supplies at the Buckman well-field.

The structure of the aquifer architecture is mathematically characterized by a canonical representation of the transition probability matrix, solved by an eigenvalue decomposition method. Whereas the eigenvalue decomposition has been numerically solved previously, we show here that it can be analytically solved under the assumptions that cross-transition probabilities are dictated by facies proportions and that the juxtapositional tendencies of the facies are symmetric. Although limited by the assumptions, analytical solutions provide more immediate insights about the relationships between transition probability and facies proportion and mean length. The analytical solution is first tested by comparison with the numerical solutions and then used to represent hydrofacies architecture within expressions for the spatial covariance of conductivity and the macrodispersivity. The relationship between the longitudinal macrodispersivity and integral scale, the indicator correlation length, and the facies proportion is represented in an equation for estimating the field-scale dispersivity. An example is used to show how sedimentary structures, conductivity contrasts, and facies mean lengths affect the scales of the macrodispersivity. Copyright 2007 by the American Geophysical Union.

We report colocated seismic and infrasound observations from reentry of NASA's Stardust sample return capsule (SSRC) on 15 January 2006. The velocity of the SSRC (initially 12.5 km/s) was the highest ever for an artificial object, lying near the low end of the 11.2-72 km/s range typical of meteoroids. Our infrasonic/seismic recordings contain an initial N wave produced by the hypersonic shock front, followed approximately 10 s later by an enigmatic series of weak, secondary pulses. The seismic signals also include an intervening dispersed wave train with the characteristics of an air-coupled Rayleigh wave. We determine an acoustic-seismic coupling coefficient of 7.3 + or - 0.2 mu m s (super -1) /Pa. This represents an energy admittance of 2.13 + or - 0.15%, several orders of magnitude larger than previous estimates derived from earthquake or explosive analogs. Theoretical seismic response was computed using in situ V (sub P) and V (sub S) measurements, together with laboratory density measurements from samples of the clay-rich playa. Treatment of the air-ground interface as an idealized air-solid contact correctly predicts the initial pulse shape but underestimates its seismic amplitude by a factor of approximately 2. Full-wave synthetic seismograms simulate the air-coupled Rayleigh wave and suggest that the secondary arrivals are higher-order Airy phases. Part of the infrasound signal appears to arise from coupling of ground motion into the air, much like earthquake-induced sounds. Copyright 2007 by the American Geophysical Union.

Transmission matrices can be used to estimate age-dependent forces of infection in age-structured, compartmental models for the study of infectious diseases. We analyze the social network generated by the synthetic population of Portland and extract mixing patterns. Our results show that the mixing within the population consists of two groups, children and adults. Children interact most frequently with other children close to their own age, while adults interact with a wider range of age groups and the durations of typical adult contacts are shorter than typical contacts between children. Furthermore, the transmission matrix shows that children are more likely to acquire infection than adults. All rights reserved, Elsevier JF - Social networks AU - Valle, S.Y.

Therefore, a renewed interest in 'harder-to-get' unconventional fuels has emerged in both industry and government with directed focus on world class hydrocarbon resources within a corridor extending from Canada southward through the Rocky Mountain States. Within this Western Energy Corridor, co-located with significant conventional hydrocarbon and renewable energy resources, lie some of the world's richest unconventional hydrocarbon resources in oil shales, oil sands and coal for coal-to-liquid conversion. However, development of these resources poses substantial environmental concerns as well as increasing competition for limited resources of water and habitat. With large-scale energy development in the predominantly rural region, local communities, infrastructures, and economies will face increasing demands for roads, electricity, law enforcement, labor, and other support services. The Western Energy Corridor Initiative (WECI) seeks to develop an integrated assessment of the impacts of unconventional fuel development, the interrelationships of planned energy developments in different basins, and the resultant demands placed on the region. This initial WECI study focuses on two of the most important current issues for industry, regulators, and stakeholders -- the assessment of carbon and water resources issues, impacts, and management strategies. Through scenario analyses using coupled systems and process level models, this study investigates the viability of integrated development of multiple energy resources in a carbon neutral and environmentally acceptable manner, and the interrelationships of various energy resource development plans. The modeling framework is designed to extend to include infrastructure, employment, training, fiscal and economic demands placed on the region as a result of various development and climate change scenarios. The multi-scale modeling approach involves a systems dynamics (SD) modeling framework linked with more detailed models such as one for basin-scale hydrology investigating the spatial relationships of water rights and requirements, reservoir locations, and climate change impacts (the details of the SD model and the hydrologic model are presented in other contributions by Pasqualini et al. and Wilson et al.). A link to a CO2 sequestration performance assessment model is also being built to enable analysis of alternative carbon management options. With these evolving capabilities, our analyses consider interdependent demands and impacts placed on the region for various development scenarios.

CO2-PENS is a hybrid process/system model composed of a library of process level modules linked together to allow simulations to span a range of spatial and temporal scales. SACROC is the oldest CO2-EOR operation in the Permian Basin and has been operational for over 35 years. We describe how CO2-PENS is used to couple CO2 migration at three different scales; from a reservoir module, through a borehole leakage module, and into an aquifer impact module. Both the reservoir module and wellbore leakage module are based on abstractions of the underlying physics of multiphase fluid flow, using reductions in complexity to allow fast Monte-Carlo simulation while capturing the behavior of these processes. Finally, we show how results from CO2-PENS can be used to delineate areas that are susceptible to ground water impacts from CO2 leakage and discuss how this information can be used in risk analysis.

In order for wellbore leakage to occur, km-scale processes must deliver CO sub(2) from the point of injection to the wellbore. But, in order for the wellbore to actually leak, μ m-scale processes must operate to allow CO sub(2) to flow up the wellbore. In this study, we describe experiments and modeling of microscale processes accompanying CO sub(2) leakage along the cement-casing interface. This work fits within a broader predictive study of CO sub(2) sequestration performance (Viswanathan et al. 2008, Env Sci and Tech, in press) that includes calculation of CO sub(2)-migration times to wellbores. Experiments carried out in this report consisted of synthetic wellbore systems constructed of Portland cement and casing-grade steel in which a mixture of CO sub(2) and brine were forced along the cement-casing interface at in situ sequestration conditions (40 ° C and 14 MPa). The CO sub(2)-brine mixture was pre- equilibrated by flow through limestone before encountering the cement-casing composite. (The limestone- equilibrated fluid was calculated to be strongly out of equilibrium with both cement and the casing.) We used a high CO sub(2)-brine flux (10-20 ml/hour along the interface) and hypothesized that the interface would widen with time due to dissolution of either or both cement and steel. In addition to experiments, we conducted reactive transport modeling of cement reactivity using FLOTRAN, which was modified to allow representation of solid solution in the dominant cement phase, calcium-silicate-hydrate. We also developed a corrosion model for the steel. The experimental results showed that the steel was more reactive than the Portland cement. Extensive deposits or oxidation products of FeCO sub(3)-rich material developed at the interface and in some places led to an apparent closure of the interface despite the large flux through the system. In contrast, alteration of the cement appeared to be limited by diffusion of CO sub(2) into the cement matrix and carbonation of the cement to CaCO sub(3). The cement interface did not appear to have been significantly eroded. The experiment was used to calibrate numerical models for corrosion rates and for cement carbonation. These results were applied to interpret samples recovered from a CO sub(2)-enhanced oil recovery field (SACROC in West Texas; Carey et al. 2007, Int J. Greenhouse Gas Control, 1: 75-85). The results suggest that CO sub(2)-brine flux must have been limited along the cement-casing interface because the casing showed very little corrosion. They also suggest that CO sub(2) penetration along the cement-formation interface was limited in volume because the depth of carbonation at SACROC was limited. These microscale models suggest that cement-casing flow has the potential to be self-limiting due to precipitation of CO sub(2) and that standard logging measurements of casing integrity can be used to assess whether significant flow of CO sub(2)-brine has occurred at the casing interface.

Our instrument measured aerosol absorption, scattering and single scattering albedo at 405, 532, and 781 nm. There were 42 complementary measurements of cloud microphysics, aerosol chemistry, and ice composition. On numerous flights we intercepted and interrogated pervasive pollution layers aloft Alaska. The absorption and scattering signals occurred in layers from 1 to 6 km above the surface and approached 200 to 30 (Mm) super(-1) respectively. Alternating light and dark aerosol layers with single scatter albedo ranging from 0.7 to 0.95 were evident, and they extended over vast areas. Real time satellite data assimilated transport models indicate that this pollution was imported from Chinese dust storms and Siberian fires as well as from Eurasian energy sectors. Our wavelength dependent optical properties are used to diagnose the soot, dust, sulfate and organic components of this complex soup of pollutants. We are testing the fidelity of our diagnostics by analyzing chemical compositions from a single particle laser ablation spectrometer instrument developed by Pacific Northwest National Laboratory. We use our optical observations to estimate a direct radiative forcing by pollution of the order of 10 to 30 of W m super(- 2). This forcing by aerosols is much larger than that by greenhouse gases. Our results underscore the need to accurately treat long range pollution transport in models to simulate the observed rapid melting of the Arctic ice sheet.

However, the challenge in obtaining milligrams of isotopically labeled TMPs to study these highly hydrophobic peptides by nuclear magnetic resonance (NMR) is significant. In the present work, a protocol is developed to produce, isotopically label, and purify TMPs in high yield as well as to initially characterize the TMPs with CD and both solution and solid-state NMR. Six TMPs from three integral membrane proteins, CorA, M2, and KdpF, were studied. CorA and KdpF are from Mycobacterium tuberculosis, while M2 is from influenza A virus. Several milligrams of each of these TMPs ranging from 25 to 89 residues were obtained per liter of M9 culture. The initial structural characterization results showed that these peptides were well folded in both detergent micelles and lipid bilayer preparations. The high yield, the simplicity of purification, and the convenient protocol represents a suitable approach for NMR studies and a starting point for characterizing the transmembrane domains of membrane proteins.

Red diode lasers minimize power consumption and cost, but limit fluorophore selection. Low-cost DPSS laser pointer modules could possibly offer increased wavelength selection but presumed emission instability has limited their use. A $160 DPSS 532 nm laser pointer module was first evaluated for noise characteristics and then used as the excitation light source in a custom-built flow cytometer for the analysis of fluorescent calibration and alignment microspheres. Eight of ten modules tested were very quiet (RMS noise 0.6% between 0 and 5 MHz). With a quiet laser pointer module as the light source in a slow-flow system, fluorescence measurements from alignment microspheres produced CVs of about 3.3%. Furthermore, the use of extended transit times and 1 mW of laser power produced both baseline resolution of all 8 peaks in a set of Rainbow microspheres, and a detection limit of <20 phycoerythrin molecules per particle. Data collected with the transit time reduced to 25 s (in the same instrument but at 2.4 mW laser output) demonstrated a detection limit of 75 phycoerythrin molecules and CVs of about 2.7%. The performance, cost, size, and power consumption of the tested laser pointer module suggests that it may be suitable for use in conventional flow cytometry, particularly if it were coupled with cytometers that support extended transit times.

Our objectives in this research are to examine these vegetation changes in detail and to determine whether they translated to changes in hydrological processes. We chose the Rio Ojo Caliente, a subbasin of the Rio Grande, as a study site since a significant portion of the woodland ecosystem (pinon-juniper) was affected. Examining a remotely-sensed vegetation index (1-km AVHRR NDVI from 1989 to 2006), there is an increasing trend in the mean NDVI from 1989 to 1998 (pre-drought period), a decreasing trend from 1999 to 2003 (drought period), and a dramatic increasing trend from 2004 to 2006 (post-drought period) in which the mean NDVI rebounds to pre- drought magnitudes. Streamflow records from 1932 to 2006 show the watershed to be primarily spring snowmelt-driven, although monsoonal summer precipitation also plays a significant role. We compare the temporal variability in the streamflow to the NDVI, including the mean, anomalies from the mean, and seasonally- based duration curves, and find significant correlations (correlation coefficient ρ = -0.61) between the streamflow and NDVI at approximately a three-month lag (NDVI lagging streamflow). In analyzing the three phases of the drought, the correlation is slightly stronger during the pre-drought (ρ = -0.64) and drought (ρ = -0.65) periods, yet markedly stronger during the post-drought period (ρ = -0.74). This suggests that the coupling between vegetation water use and streamflow is tighter after the drought. This may be attributable to the reduction in the less-responsive overstory (pinnon mortality) and increase in the more-responsive understory (grasses and shrubs exploiting newly available resources). Temporal patterns in gauge-based precipitation (frozen and unfrozen) and air temperature, and spatial-temporal patterns in PRISM precipitation, air temperature, and a soil moisture index are also compared to the NDVI. While the vegetation composition was altered to a great degree in the Rio Ojo Caliente Basin, the system rapidly recovered both photosynthetically and hydrologically during the post-drought wet period, although the dynamic between vegetation water use and streamflow was slightly altered. The aim of this research is to explore the consequences of a severe drought married with elevated temperatures on vegetation and water resources. As the intensity and frequency of droughts are expected to increase in the southwestern U.S. with rising temperatures (IPCC 2007), this research contributes to our knowledge of ecosystem and hydrologic response to the changing climate.

Chemicals are transported around the country via trains and trucks and often go through populated areas on their journey. Many of the chemicals, like chlorine and phosgene, are toxic and when released into the air are heavier-than-air dense gases that hug the ground and result in high airborne concentrations at breathing level. There is considerable concern about the vulnerability of these stored and transported chemicals to terrorist attack and the impact a release could have on highly-populated urban areas. There is the possibility that the impacts of a dense gas release within a city would be exacerbated since the buildings might act to trap the toxic cloud at street level and channel it over a large area down side streets. However, no one is quite sure what will happen for a release in cities since there is a dearth of experimental data. There are a number of fast-running dense gas models used in the air pollution and emergency response community, but there are none that account for the complex flow fields and turbulence generated by buildings. As part of this presentation, we will discuss current knowledge regarding dense gas releases around buildings and other obstacles. We will present information from wind tunnel and field experiments, as well as computational fluid dynamics modeling. We will also discuss new fast response modeling efforts which are trying to account for dense gas transport and dispersion in cities.

Tripling the anthropogenic aerosols over China and India has a small cooling effect (about -0.12degC) on the global mean surface air temperature with a slight reduction in global mean precipitation by similar to -0.8%. On the other hand, global reduction of anthropogenic aerosols by a factor of ten would warm the global surface temperatures by 0.4 degC - 0.8 degC in less than 10 years after the reduction takes place as well as an increase in global precipitation by 3.0% - 3.3%. Comparisons of NCAR and NASA model simulations also suggest that the indirect effects of aerosols are about 1-2 times the direct effects of aerosols. Tripling Asian anthropogenic aerosols results in regional cooling and a reduction in precipitation primarily in Asia, with cooling (warming) also noted over the high latitudes of Northern (Southern) Hemisphere. Warming and increase in precipitation in the case of global reduction of aerosols are concentrated mainly over polluted land areas in both hemispheres. Tropical regions experience large changes in precipitation in both scenarios. We provide new insights into the climate model sensitivities of global mean temperatures and rainfall to aerosol forcing. Our results underscore the urgency of reducing greenhouse gas accumulation rates as the world reduces air pollution to improve human health and that potential increased Asian pollution, offsets only a small fraction of the warming by greenhouse gases.

One of the models modules produces an approximated three-dimensional wind field around buildings using an empirical diagnostic approach. A second module calculates the contaminant transport and dispersion using an urbanized Lagrangian random-walk dispersion model, incorporating gradient diffusion and non-local mixing to produce building-induced turbulence. QUICs GUI includes a city builder for creating building domains, a meteorology builder to specify wind profiles, and a source GUI for location(s), geometry, type, and amount of release. Recent code improvements include the ability to release, track, and deposit particles of multiple size distribution, an explosive release accompanied by a buoyant plume, and a post-processing Depositional calculator, which sums deposition on horizontal and vertical surfaces, as a function of particle size bins. Los Alamos National Laboratory and the U.S. Environmental Protection Agency have worked to formulate hypothetical RDD urban releases with the objective of a pre-emptive prediction of contaminant air concentrations, their dispersion, and subsequent surface contaminant deposition, and relate these concentrations to the Protective Action Guides for emergency response and clean-up concentration metrics, with provided examples. We will discuss model development, applications, and direction for further research.

AN - 20002868; 8326637 AB - In this presentation results from a cloud-resolving model that can efficiently examine the impact of aerosols on non-drizzling stratus clouds will be shown. Because the model tracks aerosols and cloud droplets in a Lagrangian framework, it does not suffer from numerical errors associated with advection and unlike most Eulerian approaches, the method can accurately track cloud boundaries as they move across a grid cell. The model is able to reproduce cloud water mixing ratio and vertical velocity statistics from the DYCOMS-II field program. The ability of the model to assess the impact of changes in aerosol number and composition on a stratus deck will be presented. Specifically, by using activation curves appropriate for soluble, insoluble, or a mixture of both types of aerosols and for certain extreme aerosol regimes, i.e., a majority of the aerosols are hydrophobic, limiting situations will be examined in this numerical framework that may, in fact, occasionally occur in the atmosphere, e.g., an oceanic stratus field downwind of a large urban area. Expectedly, results from these simulations support previous ship track observations that for increasing aerosol numbers cloud number concentrations increase, whereas cloud droplet radii decrease near cloud top. But, these simulations also suggest that the correlation between cloud number concentration and aerosol number concentration may be a function of aerosol type.

Shock-loading was performed below (12.5GPa) and above (14GPa) the pressure-induced epsilon phase transition occurring at 13GPa. Using electron microscopy and electron backscatter diffraction, twinning and microbanding were observed only in the shock-prestrained specimens. Quasi-static compression tests showed an increase in yield and compressive strengths with increased peak shock stress. SHPB tests produced shear localization in all specimens, with shear banding occurring only in the shock-prestrained specimens. Transmission electron microscopy revealed that, at the shear band edge, elongated cells dominate the microstructure, with more shock-induced twins remaining intact in the 12.5GPa specimen than in the 14GPa specimen.

Such higher-level data often correspond to train, subsystem or system failure events. The fully Bayesian approach also automatically propagates the highest-level data to lower levels in the fault tree. A simple example illustrates our approach.

However, they are energy intensive, have a higher carbon footprint than conventional fossil fuels and present significant demands on water resources in the Rocky Mountain West. We are applying the Watershed Analysis Risk Management Framework (WARMF)basin-scale hydrologic model to address the impacts of climate change and variability on water resources within the context of energy and fuel development in the upper Colorado River basin. WARMF performs physics based energy and water balances on a sub-watershed basis and routes flow through soils and a network of streams, lakes and reservoirs to a watershed outlet. A climate change module has been developed to modify historical meteorological data in order to examine the impacts of climate change scenarios in the basin. The model is parameterized and calibrated for the White, Upper Colorado and Gunnison Rivers in Colorado from their headwaters to the Utah border. These rivers are the most likely to be impacted by new extractions of water for oil shale development in the Piceance Basin in Western Colorado. The model predicts that a three degree Celsius change in temperature could result in an average annual reduction in stream flow by 15 to 20 percent and a shift toward earlier snowmelt runoff. In addition, model output is used within a systems dynamics modeling framework to examine water resource management strategies for a range of energy production growth scenarios and the interdependencies between water use, energy production, carbon management, population growth, infrastructure, and economics in western basins.

The largest reserve of oil shale in the world is located in the western interior of North America, and includes parts of Colorado, Utah, and Wyoming. Development of oil shale in this area could reduce or eliminate the U.S. dependence on foreign fuel sources. However, oil shale production carries a number of potential environmental impacts. Fuel production associated with oil shale will create increasing competition for limited resources such as water, while potentially negatively impacting air quality, water quality, habitat, and wildlife. Water use, wastewater management, greenhouse gas emissions, air pollution, and land use are the main environmental issues that oil shale production involves. A proper analysis of the interrelationships between these factors and those of the new energy needs required for production is necessary to avoid serious negative impacts to the environment and the economies. We have developed a system dynamics integrated assessment model to evaluate potential fuel production capacity from oil shale within the limits of environmental quality, land use, and economics. Recognizing that the impacts of oil shale development are the outcomes of a complex process that involve water, energy, climate, social pressures, economics, regulations, technical advances, etC. and especially their couplings and feedbacks, we developed our model using the system dynamics (SD) modeling approach. Our SD model integrates all of these components and allows us to analyze the interdependencies among them. Our initial focus has been to address industry, regulator, and stakeholder concerns regarding the quantification and management of carbon and water resources impacts. The model focuses on oil shale production in the Piceance Basin in Colorado, but is inherently designed to be extendable to larger regions, levels of production, and different unconventional fuels.

AN - 68257754; 17644643 AB - The bacterial reduction of actinides has been suggested as a possible remedial strategy for actinide-contaminated environments, and the bacterial reduction of Pu(VI/V) has the potential to produce highly insoluble Pu(IV) solid phases. However, the behavior of plutonium with regard to bacterial reduction is more complex than for other actinides because it is possible for Pu(IV) to be further reduced to Pu(III), which is relatively more soluble than Pu(IV). This work investigates the ability of the metal-reducing bacteria Geobacter metallireducens GS15 and Shewanella oneidensis MR1 to enzymatically reduce freshly precipitated amorphous Pu(IV) (OH)(4) [Pu(IV)(OH)(4(am))] and soluble Pu(IV)(EDTA). In cell suspensions without added complexing ligands, minor Pu(III) production was observed in cultures containing S. oneidensis, but little or no Pu(III) production was observed in cultures containing G. metallireducens. In the presence of EDTA, most of the Pu(IV)(OH)(4(am)) present was reduced to Pu(III) and remained soluble in cell suspensions of both S. oneidensis and G. metallireducens. When soluble Pu(IV)(EDTA) was provided as the terminal electron acceptor, cell suspensions of both S. oneidensis and G. metallireducens rapidly reduced Pu(IV)(EDTA) to Pu(III)(EDTA) with nearly complete reduction within 20 to 40 min, depending on the initial concentration. Neither bacterium was able to use Pu(IV) (in any of the forms used) as a terminal electron acceptor to support growth. These results have significant implications for the potential remediation of plutonium and suggest that strongly reducing environments where complexing ligands are present may produce soluble forms of reduced Pu species.

Here we show that periodic supercontinent cycles are unlikely if thermal instabilities originating at the core-mantle boundary are of sufficient strength. We couple multiple mobile continents with vigorous mantle convection in a spherical geometry. Regular supercontinent cycles lasting 400 + or - 50 m.y. occur in idealized models with three continents and a mantle heated purely from within by radioactive decay. In a model incorporating six continents and strong mantle plumes, this regularity is broken and supercontinents form only sporadically. Our results suggest that periodic supercontinent cycles are unlikely to occur in realistic Earth models.

We summarize physical volcanological, geochemical, and time-volume characteristics of the Plio-Pleistocene part of the Southwestern Nevada Volcanic Field (SNVF) as an example of an extremely low volume-flux end member of basaltic fields. The SNVF has produced 17 volcanoes of dominantly trachybasaltic composition over the past 5 Myr with a total volume of slightly less than 6 km (super 3) . Eruptive fissure lengths, volumes, and inferred lava effusion rates decreased between Pliocene- and Pleistocene-age volcanoes. Major element data suggest that most of the magmas underwent similar degrees of fractionation during ascent, and trace element compositions indicate a decrease in the degree of partial melting of the lithospheric mantle source since approximately 3 Ma. Isotopic data support an interpretation wherein magmas ascended relatively quickly from their source regions with little if any interaction with crustal rocks. Relationships between age and cumulative erupted volume indicate that the repose interval between eruptive episodes is determined by the volumes of prior episodes and, since approximately 3 Ma, an average eruption rate of approximately 0.5 km (super 3) /Myr, i.e., the field is time-predictable. All of these features support a model wherein magmatism is a passive result of regional tectonic strain. Partial melt resides in pockets of lithospheric mantle that are relatively enriched in hydrous minerals; slow deformation focuses melt, occasionally resulting in sufficiently high melt pressure to drive dikes upward and feed eruptive episodes. Larger source volumes result in larger eruptive volumes and wider dikes that relieve relatively more strain in the crust than smaller volume events, and therefore are followed by longer repose intervals required for recovery of crustal stresses. We suggest that time-predictability may be a fundamental property of tectonically controlled basaltic fields, where melt accumulation and ascent are controlled by tectonic strain rate. This behavior contrasts with magmatically controlled fields where magma flux is sufficiently high to overwhelm local tectonic strain, eruptions are primarily caused by magmatic processes that build pressure in reservoirs, and the systems are more likely to be volume-predictable.

It is well known that the youngest Ko'olau (Makapu'u-stage) shield lavas define a geochemical endmember for Hawaiian lavas in terms of CaO and SiO (sub 2) contents and isotopic ratios of O, Sr, Nd, Hf, Pb, and Os. We find that their MnO content is also distinct. Despite the small range in MnO, 0.146 to 0.176 wt%, the precision of our data is sufficient to show that among unaltered Ko' olau lavas MnO content is correlated with Nd-Hf-Pb isotopic ratios, La/Nb and Al (sub 2) O (sub 3) /CaO elemental ratios, and contents of SiO (sub 2) , MgO and Na (sub 2) O+K (sub 2) O adjusted for olivine fractionation. These trends are consistent with two-component mixing; one endmember is a SiO (sub 2) -rich, MnO-, and MgO-poor dacite or andesite melt, generated by low degree (10-20%) partial melting of eclogite. Since this low-MgO endmember (dacite or andesite melt) has very low FeO and MnO contents, mixing of high Fe/Mn dacite or andesite melt with a MgO-rich picritic melt, the other endmember, does not significantly increase the Fe/Mn in mixed magmas; consequently, Ko'olau and Kilauea lavas have similar Fe/Mn. We conclude that the high Fe/Mn in Hawaiian lavas relative to mid-ocean ridge basalt originates from the high MgO endmember in Hawaiian lavas.

Either the Allende CAIs were isotopically disturbed or the differentiation of magmatic irons (groups IIAB, IID, IIIAB, and IVB) all occurred 10 (super 3) , which is lowered by the ubiquitous presence of metal inclusions to (super 180) Hf/ (super 184) W>10 in bulk fassaite. Metal alloy (Ni approximately 50%) is the sole host of W ( approximately 500 ppm) in Ef2, while opaque assemblages (OAs) and secondary veins are the hosts of W in Golfball. A large metal alloy grain from Ef2, EM2, has (super 180) Hf/ (super 184) W100 ppm W with no detectable Pt or S. This vein provides evidence for transport of oxidized W in the CAI. Because of the ubiquitous distribution of OAs, interpretations of the (super 182) Hf- (super 182) W isochron reported for Allende CAIs include: (i) all W in the OAs was derived by alteration of CAI metal, or (ii) at least some of the W in OAs may have been equilibrated with radiogenic W during metamorphism of Allende. Since (ii) cannot be ruled out, new (super 182) Hf- (super 182) W determinations on CAIs from reduced CV3 chondrites are needed to firmly establish the initial W isotopic composition of the solar system.

We assume that the constitutive relation between the unsaturated hydraulic conductivity and the pressure head follows an exponential model, and treat the saturated hydraulic conductivity K (sub s ) as a random function and the pore size distribution parameter alpha as a random constant. Unlike the solution given in Lu and Zhang (2004) in which Kirchhoff transformation was used and the solution to pressure head variance was presented as a function of (cross-)covariances related to the intermediate, Kirchhoff-transformed variable, the solution to the pressure head variance presented in this paper is an explicit function of the input variabilities. In addition, we also give analytical solutions to the statistics of the unsaturated hydraulic conductivity and the effective water content. These first-order analytical solutions are compared with those from Monte Carlo simulations. We also investigated the effect of uncertain boundary conditions, the relative contribution of input variabilities to the head variance, and the possible errors introduced by treating the correlated alpha field as a random constant in the analytical solutions. The results indicate that the uncertain constant head at the bottom of a deep soil column may not have a significant effect on predicting flow statistics in the upper portion of the column. Furthermore, it is found that treating alpha as a random constant is justified when the correlation length of alpha is relatively large as compared to the layer thickness.

DOC concentrations decreased, with P concentrations, along a water quality gradient from the agriculturally impacted areas in the northern Everglades to the more pristine Everglades National Park. delta 13C values of DOC in the area reflect contributions of both wetland vegetation and sugarcane from agriculture. Radiocarbon ages of DOC, POC and DIC in the Everglades ranged from 2.01ka BP to '>modern'. The old 14C ages of DOC and POC were found in impacted areas near the Everglades Agricultural Area (EAA) in the northern Everglades. In contrast, DOC and POC in pristine marsh areas had near modern or '>modern' 14C ages. These data indicate that a major source of POC and DOC in impacted areas is the degradation of historic peat deposits in the EAA. In the pristine areas of the marsh, DOC represents a mix of modern and historic C sources, whereas POC comes from modern primary production as indicated by positive Delta 14C values, suggesting that DOC is transported farther away from its source than POC. High Delta 14C values of DIC indicate that dissolution of limestone bedrock is not a significant source of DIC in the Everglades wetlands. As a restored wetland moves towards its 'original' or 'natural'state, the 14C signatures of DOC should approach that of modern atmosphere. In addition, measurements of concentration and C isotopic composition of DOC in two small constructed wetlands (i.e., test cells) indicate that these freshwater wetland systems contain a labile DOC pool with rapid turnover times of 26-39days and that the test cells are overall net sinks of DOC.

Bioanalyte sensing schemes based on coupling of reversible nanotube fluorescence quenching to redox reactions paired to enzymatic peroxide generation have also been pursued super(5). Here we show a new approach to highly sensitive nanotube-based optical sensing. Single-walled carbon nanotubes interacting with dye-ligand conjugates-a redox-active dye molecule that is covalently bound to a biological receptor ligand (such as biotin in this case)-showed fluorescence quenching. Further interaction between the receptor ligand on the conjugates and target analytes (avidin in this case) induced the recovery of the quenched fluorescence, forming the basis of the sensing scheme. Nanomolar sensitivity was attained with high specificity for the target analyte. This is a versatile approach because a wide range of conjugation possibilities exists between the potential receptors and redox quenchers.

7542097 AB - Diffusion cell experiments were conducted to measure nonsorbing solute matrix diffusion coefficients in forty-seven different volcanic rock matrix samples from eight different locations (with multiple depth intervals represented at several locations) at the Nevada Test Site. The solutes used in the experiments included bromide, iodide, pentafluorobenzoate (PFBA), and tritiated water ( super(3)HHO). The porosity and saturated permeability of most of the diffusion cell samples were measured to evaluate the correlation of these two variables with tracer matrix diffusion coefficients divided by the free-water diffusion coefficient (D sub(m)/D super( approximately equal to )). To investigate the influence of fracture coating minerals on matrix diffusion, ten of the diffusion cells represented paired samples from the same depth interval in which one sample contained a fracture surface with mineral coatings and the other sample consisted of only pure matrix. The log of (D sub(m)/D super( approximately equal to )) was found to be positively correlated with both the matrix porosity and the log of matrix permeability. A multiple linear regression analysis indicated that both parameters contributed significantly to the regression at the 95% confidence level. However, the log of the matrix diffusion coefficient was more highly-correlated with the log of matrix permeability than with matrix porosity, which suggests that matrix diffusion coefficients, like matrix permeabilities, have a greater dependence on the interconnectedness of matrix porosity than on the matrix porosity itself. The regression equation for the volcanic rocks was found to provide satisfactory predictions of log(D sub(m) /D super( approximately equal to )) for other types of rocks with similar ranges of matrix porosity and permeability as the volcanic rocks, but it did a poorer job predicting log(D sub(m)/D super( approximately equal to )) for rocks with lower porosities and/or permeabilities. The presence of mineral coatings on fracture walls did not appear to have a significant effect on matrix diffusion in the ten paired diffusion cell experiments.

15326441 AB - Dengue, a vector-borne disease, thrives in tropical and subtropical regions worldwide. A retrospective analysis of the 2002 dengue epidemic in Colima located on the Mexican central Pacific coast is carried out. We estimate the reproduction number from spatial epidemic data at the level of municipalities using two different methods: (1) Using a standard dengue epidemic model and assuming pure exponential initial epidemic growth and (2) Fitting a more realistic epidemic model to the initial phase of the dengue epidemic curve. Using Method I, we estimate an overall mean reproduction number of 3.09 (95% CI: 2.34, 3.84) as well as local reproduction numbers whose values range from 1.24 (1.15, 1.33) to 4.22 (2.90, 5.54). Using Method, the overall mean reproduction number is estimated to be 2.0 (1.75, 2.23) and local reproduction numbers ranging from 0.49 (0.0, 1.0) to 3.30 (1.63, 4.97). Method I systematically overestimates the reproduction number relative to the refined Method, and hence it would overestimate the intensity of interventions required for containment. Moreover, optimal intervention with defined resources demands different levels of locally tailored mitigation. Local epidemic peaks occur between the 24th and 35th week of the year, and correlate positively with the final local epidemic sizes ([rho] = 0.92, P-value 0.001). Moreover, final local epidemic sizes are found to be linearly related to the local population size (P-value 0.001). This observation supports a roughly constant number of female mosquitoes per person across urban and rural regions.

However, continuing viral replication in the presence of drug therapy can lead to the emergence of drug-resistant virus variants, which subsequently results in incomplete viral suppression and a greater risk of disease progression. In this paper, we use a simple mathematical model to study the mechanism of the emergence of drug resistance during therapy. The model includes two viral strains: wild-type and drug-resistant. The wild-type strain can mutate and become drug-resistant during the process of reverse transcription. The reproductive ratio sub(0) for each strain is obtained and stability results of the steady states are given. We show that drug-resistant virus is more likely to arise when, in the presence of antiretroviral treatment, the reproductive ratios of both strains are close. The wild-type virus can be suppressed even when the reproductive ratio of this strain is greater than1. A pharmacokinetic model including blood and cell compartments is employed to estimate the drug efficacies of both the wild-type and the drug-resistant strains. We investigate how time-varying drug efficacy (due to the drug dosing schedule and suboptimal adherence) affects the antiviral response, particularly the emergence of drug resistance. Simulation results suggest that perfect adherence to regimen protocol will well suppress the viral load of the wild-type strain while drug-resistant variants develop slowly. However, intermediate levels of adherence may result in the dominance of the drug-resistant virus several months after the initiation of therapy. When more doses of drugs are missed, the failure of suppression of the wild-type virus will be observed, accompanied by a relatively slow increase in the drug-resistant viral load.

The structural resurgent dome of the Valles caldera was uplifted approximately 1000 m above the surrounding caldera floor during resurgence. The upper Bandelier Tuff, which yields an age of 1.256 + or - 0.010 Ma (2sigma ; ages relative to Fish Canyon tuff sanidine at 28.02 Ma), is the lower constraint on the timing of resurgence. The oldest postcollapse ring fracture dome, Cerro del Medio, is the upper time constraint and yields an age of 1.229 + or - 0.017 Ma for one of its oldest flow lobes. Therefore resurgent uplift probably occurred within 54 ka, at a minimum rate of 1.9 cm/yr. Sanidine phenocrysts from rhyolites of the postcollapse intracaldera Deer Canyon and Redondo Creek members yield (super 40) Ar/ (super 39) Ar single-crystal laser fusion ages ranging from 1.229 + or - 0.013 Ma to 1.283 + or - 0.017 Ma (Deer Canyon Member; n = 8) and 1.208 + or - 0.017 Ma to 1.239 + or - 0.017 Ma (Redondo Creek Member; n = 4). With one exception from each unit, these ages are statistically indistinguishable from the upper Bandelier Tuff, indicating that eruption of these postcollapse rhyolites probably commenced shortly after caldera formation. Melt inclusion hosted excess argon was not found to have a measurable effect on the age of sanidine from the upper Bandelier Tuff or the Deer Canyon Member.

The technological importance of these materials, however, depends on their radiation damage resistance properties at elevated temperatures. We investigated the degree of retention of 33keV super(4)He super(+) implanted at temperatures ranging from 490 super(o)C to 660 super(o)C in CuNb multilayer composites with layer thicknesses from 4nm to 100nm. Analysis by elastic recoil detection (ERD) with 12MeV super(1) super(2)C super(3) super(+) beam demonstrates that the fraction of retained He decreases with increasing temperature and decreasing layer thickness, suggesting that interfaces between neighboring Cu and Nb layers serve as pathways for fast diffusion of implanted He out of the CuNb multilayer composites. Atomic-scale simulations of radiation damage cascades indicate that this property stems from the ability of CuNb interfaces to quickly absorb defects created during these cascades.

Tests are presented for two-dimensional and three-dimensional pumped systems that are homogeneous or that have simple heterogeneity. The parent and child grids are simulated using the block-centered finite-difference MODFLOW and control-volume finite-element FEHM models, respectively. The models are solved iteratively through head-dependent (child model) and specified-flow (parent model) boundary conditions. Boundary conditions for models with nonmatching grids or zones of different hydraulic conductivity are derived and tested against heads and flows from analytical or globally-refined models. Results indicate that for homogeneous two- and three-dimensional models with matched grids (integer number of child cells per parent cell), the new method is nearly as accurate as the coupling of two MODFLOW models using the shared-node method and, surprisingly, errors are slightly lower for nonmatching grids (noninteger number of child cells per parent cell). For heterogeneous three-dimensional systems, this paper compares two methods for each of the two sets of boundary conditions: external heads at head-dependent boundary conditions for the child model are calculated using bilinear interpolation or a Darcy-weighted interpolation; specified-flow boundary conditions for the parent model are calculated using model-grid or hydrogeologic-unit hydraulic conductivities. Results suggest that significantly more accurate heads and flows are produced when both Darcy-weighted interpolation and hydrogeologic-unit hydraulic conductivities are used, while the other methods produce larger errors at the boundary between the regional and local models. The tests suggest that, if posed correctly, the ghost-node method performs well. Additional testing is needed for highly heterogeneous systems. Abstract Copyright (2007) Elsevier, B.V.

Here we focus on hepatitis B virus (HBV) dynamics during the acute stages of the infection and analyze the immune mechanisms responsible for viral clearance. We start by presenting the basic model used to interpret HBV therapy studies conducted in chronically infected patients. We then introduce additional models to study acute infection where immune responses presumably play an important role in determining whether the infection will be cleared or become chronic. We add complexity incrementally and explain each step of the modeling process. Finally, we validate the model against experimental data to determine how well it represents the biological system and, consequently, how useful are its predictions. In particular, we find that a cell-mediated immune response plays an important role in controlling the virus after the peak in viral load.

AN - 70668949; 17596864 AB - UNLABELLEDWhen patients chronically infected with hepatitis C virus (HCV) are placed on antiviral therapy with pegylated interferon (IFN)-alpha or IFN-alpha plus ribavirin (RBV), HCV RNA generally declines in a biphasic manner. However, a triphasic decline has been reported in a subset of patients. A triphasic decline consists of a first phase (1-2 days) with rapid virus load decline, followed by a "shoulder phase" (4-28 days) in which virus load decays slowly or remains constant, and a third phase of renewed viral decay. We show that by including the proliferation of both uninfected and infected cells, a viral kinetic model can account for a triphasic HCV RNA decay. The model predicts that a triphasic decline occurs only in patients in which a majority of hepatocytes are infected before therapy. The shoulder phase does not represent the intrinsic death rate of infected cells, but rather the third phase slope is close to the intrinsic death rate of infected cells when overall drug efficacy is close to 1.CONCLUSIONTriphasic responses can be predicted from a generalization of existent viral kinetic models through the inclusion of homeostatic proliferation of hepatocytes. This generalized model can also explain the viral kinetics seen in flat partial responders. Finally, the enhanced third phase in patients treated with IFN-alpha in combination with RBV versus patients treated with IFN-alpha alone can be explained by a mutagenic effect of RBV against HCV.

Ordinary kriging, the starting point in the development of other geostatistical techniques, has a number of serious limitations, chief among which is the intrinsic hypothesis of the (second-order) stationarity of the underlying random field. Attempts to overcome this limitation have led to the development of ever more complex flavors of kriging. We pursue an opposite strategy that consists of finding the simplest possible technique that is adequate for the task of facies delineation. Guided by the principle of parsimony, we identify nearest-neighbor classification (NNC) as a viable alternative to geostatistics among deterministic techniques. We demonstrate that when used for the purpose of facies delineation, NNC, which has no fitting parameters and operational assumptions, outperforms indicator kriging, which has several parameters.

The laboratory tests included 15 separate tracer transport experiments conducted in 8 fractured cores (4 from each location) and 17 diffusion cell experiments conducted in matrix material adjacent to the fractures. All of the experiments featured two nonsorbing tracers with free diffusion coefficients differing by a factor of approximately 3 to allow the effects of diffusion to be distinguished from the effects of advection, dispersion, and source-term tailing in the experiments. When considering all the laboratory and field transport experiments collectively, the lumped mass transfer parameter that characterizes matrix diffusion rates, &frac{\phi_{\rm m}}{b}\sqrt{D_{\rm m}}; (sec (super -1/2) ) (where phi (sub m) is the matrix porosity, b is the effective fracture half-aperture, and D (sub m) is the matrix diffusion coefficient), appears to decrease as time and length scales of observation increase. However, these decreasing trends largely disappear when the laboratory and field data are considered separately, and there is little difference in D (sub m) values measured at different timescales in laboratory experiments using the same rocks. Also, the overall variability in phi (sub m) and D (sub m) in the laboratory experiments is not large enough to account for the order-of-magnitude smaller field-scale values of &frac{\phi_{\rm m}}{b}\sqrt{D_{\rm m}}; compared to lab-scale values. We conclude that experimentally observed trends of &frac{\phi_{\rm m}}{b}\sqrt{D_{\rm m}}; versus time or distance scale in saturated fractured rocks at the Nevada Test Site are dominated by differences in effective fracture apertures in the various experiments, with a tendency toward larger apertures in the field experiments. These results underscore the importance of acquiring a better understanding of the factors that control effective fracture apertures as a function of distance scale in fractured media if values of &frac{\phi_{\rm m}}{b}\sqrt{D_{\rm m}}; from laboratory and field tracer experiments are to be reliably extrapolated to time and distance scales in risk assessment models.

The KLME approach combines the Karhunen-Loeve decomposition of the underlying random conductivity field and the perturbative and polynomial expansions of dependent variables including the hydraulic head, flow velocity, dispersion coefficient, and solute concentration. The equations obtained in this approach are sequential, and their structure is formulated in the same form as the original governing equations such that any existing simulator, such as Modular Three-Dimensional Multispecies Transport Model for Simulation of Advection, Dispersion, and Chemical Reactions of Contaminants in Groundwater Systems (MT3DMS), can be directly applied as the solver. Through a series of two-dimensional examples, the validity of the KLME approach is evaluated against the classical Monte Carlo simulations. Results indicate that under the flow and transport conditions examined in this work, the KLME approach provides an accurate representation of the mean concentration. For the concentration variance, the accuracy of the KLME approach is good when the conductivity variance is 0.5. As the conductivity variance increases up to 1.0, the mismatch on the concentration variance becomes large, although the mean concentration can still be accurately reproduced by the KLME approach. Our results also indicate that when the conductivity variance is relatively large, neglecting the effects of the cross terms between velocity fluctuations and local dispersivities, as done in some previous studies, can produce noticeable errors, and a rigorous treatment of the dispersion terms becomes more appropriate.

During and following the most recent eruption in 1989-1990 the Alaska Volcano Observatory deployed up to 10 seismometers to improve real-time monitoring capabilities at Redoubt and continues to produce an annual earthquake catalog with associated arrival times for this volcano. We compute a three-dimensional P wave velocity model using double-difference tomography combined with waveform cross-correlation techniques to identify families of similar earthquakes and increase earthquake location precision at Redoubt. Absolute and differential times for well-constrained events are used to simultaneously invert for hypocenter location and P wave velocity structure. Shot and earthquake arrival times recorded by temporary stations deployed on Redoubt in July 1991 supplement the catalog picks. Double-difference tomography reduces uncertainties associated with absolute and relative earthquake locations and provides a clearer picture of three-dimensional velocity heterogeneity. All Redoubt data available through November 2005 are relocated through the three-dimensional model, and we investigate seismicity associated with the 1989-1990 eruption and compare cross-correlation coefficients to identify similar earthquakes within the catalog. Waveform similarity is high at Redoubt, especially during the eruptive phases, and event families include long-period shallow summit, hybrid, and both shallow summit and midcrust level volcano-tectonic earthquakes. We do not resolve a low-velocity feature in the three-dimensional P wave model that can be interpreted as a source magma chamber and prefer the idea of an interconnected body of dikes and sills as the source of magma erupted in 1989-1990.

To demonstrate this, we add a laterally varying upper mantle gradient to the standard P (sub n ) time-term tomography technique, and apply to a data set from Asia compiled using ground truth, event location criteria. We observe strong lateral variations in the gradient, ranging from -0.001 to 0.003 s (super -1) , with high gradients associated with the Tethys convergence zone. The gradient patterns may reflect lateral variations in the thermal gradient of the mantle lid. Variance reduction is 63% with respect to P (sub n ) tomography without gradients. Adding gradients allows the use of longer path lengths, improving velocity image definition in high-gradient regions with sparse station distribution, such as Tibet.

Hydrogen enhancements are seen at the poles, but the physical form, abundance and distribution of this hydrogen remains controversial. Using a pixon-based image reconstruction algorithm to effectively improve spatial resolution, we derive maps of the lunar south polar water-equivalent hydrogen concentration that are fully consistent with the orbital neutron measurements, with abundances greater than 0.5 wt% in some permanently shadowed locations. This is much greater than the highest solar wind hydrogen abundance in returned lunar samples, and may indicate ice between regolith grains. If the hydrogen distribution is inhomogeneous within a permanently shadowed crater, then even higher abundances are implied. In Shackleton crater, for example, the derived count rates are consistent with 10% of the crater floor area having 20-wt% water-equivalent hydrogen, and the remainder at 0.25 wt%.

AN - 20866219; 7560557 AB - It is generally accepted that plasmids containing the same origin of replication are incompatible. We have re-examined this concept in terms of the plasmid copy number, by introducing plasmids containing the same origin of replication and different antibiotic resistance genes into bacteria. By selecting for resistance to only one antibiotic, we were able to examine the persistence of plasmids carrying resistances to other antibiotics. We find that plasmids are not rapidly lost, but are able to persist in bacteria for multiple overnight growth cycles, with some dependence upon the nature of the antibiotic selected for. By carrying out the experiments with different origins of replication, we have been able to show that higher copy number leads to longer persistence, but even with low copy plasmids, persistence occurs to a significant degree. This observation holds significance for the field of protein engineering, as the presence of two or more plasmids within bacteria weakens, and confuses, the connection between screened phenotype and genotype, with the potential to wrongly assign specific phenotypes to incorrect genotypes.

These controls are specifically designed to rule out artifacts derived from 'double transformants'-i.e. cells transformed with, or infected by, two different plasmids simultaneously. These seem to have been the source of past artifacts and, as demonstrated here, are far more common than generally recognized. By following standard protocols for cloning, plasmid isolation, subcloning, in combination with functional assays, the presence of such artifacts can be ruled out.

These models typically evaluate bird behaviour by focusing on a single optimization currency, such as total migration time or energy-use, without explicitly considering trade-offs between the involved objectives. In this paper, we demonstrate that this classic single-objective approach downplays the importance of variability in bird behaviour. In the light of these considerations, we therefore propose to use a full multi-criteria optimization method to isolate the set of non-dominated, efficient or Pareto optimal solutions. Unlike single-objective optimization where there is only one combination of bird behaviour maximizing fitness, the Pareto solution set represents a range of optimal solutions to conflicting objectives. Our results demonstrate that this multi-objective approach provides important new ways of analyzing how environmental factors and behavioural constraints have driven the evolution of migratory behaviour. |l en JF - Journal of Avian Biology AU - A Vrugt, Jasper AU - van Belle, Jelmer AU - Bouten, Willem Y1 - 2007/07// PY - 2007 DA - Jul 2007 SP - 432 EP - 442 PB - Blackwell Publishing Ltd., 9600 Garsington Road VL - 38 IS - 4 SN - 0908-8857, 0908-8857 KW - Animal Behavior Abstracts; Ecology Abstracts KW - Flight KW - Aves KW - Energy KW - Migration KW - Y 25080:Orientation, Migration and Locomotion KW - D 04040:Ecosystem and Ecology Studies UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20433625?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%3Aecology&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Journal+of+Avian+Biology&rft.atitle=Pareto+front+analysis+of+flight+time+and+energy+use+in+long-distance+bird+migration&rft.au=A+Vrugt%2C+Jasper%3Bvan+Belle%2C+Jelmer%3BBouten%2C+Willem&rft.aulast=A+Vrugt&rft.aufirst=Jasper&rft.date=2007-07-01&rft.volume=38&rft.issue=4&rft.spage=432&rft.isbn=&rft.btitle=&rft.title=Journal+of+Avian+Biology&rft.issn=09088857&rft_id=info:doi/10.1111%2Fj.2007.0908-8857.03909.x LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2008-01-01 N1 - Last updated - 2011-12-13 N1 - SubjectsTermNotLitGenreText - Aves; Migration; Energy; Flight DO - http://dx.doi.org/10.1111/j.2007.0908-8857.03909.x ER - TY - JOUR T1 - Literature review of thermal and radiation performance parameters for high-temperature, uranium dioxide fueled cermet materials AN - 20262027; 8550468 AB - High-temperature fissile-fueled cermet literature was reviewed. Data are presented primarily for the W-UO2 as this was the system most frequently studied; other reviewed systems include cermets with Mo, Re, or alloys as a matrix. Failure mechanisms for the cermets are typically degradation of mechanical integrity and loss of fuel. Mechanical failure can occur through stresses produced from dissimilar expansion coefficients, voids created from diffusion of dissimilar materials or formation of metal hydride and subsequent volume expansion. Fuel loss failure can occur by high temperature surface vaporization or by vaporization after loss of mechanical integrity. Techniques found to aid in retaining fuel include the use of coatings around UO2 fuel particles, use of oxide stabilizers in the UO2, minimizing grain sizes in the metal matrix, minimizing impurities, controlling the cermet sintering atmosphere, and cladding around the cermet.

Samples were prepared via sintering in either Ar or N2 (with and without 6% H2) and at 1300 DGC or 1600 DGC. A significant difference in the hardness was measured ranging from 1000 (Kg/mm2) in samples sintered at 1600 DGC in argon to 100 (Kg/mm2) in samples sintered at 1300 DGC in nitrogen. Samples with 6% hydrogen added to the sintering environment experienced a decrease in hardness, as well as an increase in intergranular cracking as compared to samples sintered without hydrogen, suggesting hydrogen embrittlement. Grain size was more uniform in samples sintered in pure Ar as compared to Ar-H2, while the latter had a larger fraction of high angle grain boundaries than the former. Cracking around indents had a clear tendency to follow high angle boundaries, which were found to be intrinsically weak in ZrN.

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

The partition coefficient (K sub(d)) is useful for characterizing the soil-solution exchange kinetics and is an important factor for predicting relative amounts of a radionuclide transported to groundwater compared to that remaining on soil surfaces and thus available for transport through erosion processes. Measurements of K sub(d) for super(238)U are particularly useful because of the extensive use of super(238)U in military applications and associated testing, such as done at Los Alamos National Laboratory (LANL). Site-specific measurements of K sub(d) for super(238)U are needed because K sub(d) is highly dependent on local soil conditions and also on the fine soil fraction because super(238)U concentrates onto smaller soil particles, such as clays and soil organic material, which are most susceptible to wind erosion and contribute to inhalation exposure in off-site populations. We measured K sub(d) for uranium in soils from two neighboring semiarid forest sites at LANL using a U.S. Environmental Protection Agency (EPA)-based protocol for both whole soil and the fine soil fraction (diameters <45 mu m). The 7-d K sub(d) values, which are those specified in the EPA protocol, ranged from 276-508 mL g super(-1) for whole soil and from 615-2249 mL g super(-1) for the fine soil fraction. Unexpectedly, the 30-d K sub(d) values, measured to test for soil-solution exchange equilibrium, were more than two times the 7-d values. Rates of adsorption of super(238)U to soil from solution were derived using a 2-component (FAST and SLOW) exponential model. We found significant differences in K sub(d) values among LANL sampling sites, between whole and fine soils, and between 7-d and 30-d K sub(d) measurements. The significant variation in soil-solution exchange kinetics among the soils and soil sizes promotes the use of site-specific data for estimates of environmental transport rates and suggests possible differences in desorption rates from soil to solution (e.g., into groundwater or lung fluid). We also explore potential relationships between wind erosion, soil characteristics, and K sub(d)values. Combined, our results highlight the need for a better mechanistic understanding of soil-solution partitioning kinetics for accurate risk assessment.

MtrA is a member of the OmpR/PhoB family of response regulators and represents the fourth family member for which a structure of the protein in its inactive state has been determined. As is true for all OmpR/PhoB family members, MtrA possesses an N-terminal regulatory domain and a C-terminal winged helix-turn-helix DNA-binding domain, with phosphorylation of the regulatory domain modulating the activity of the protein. In the inactive form of MtrA, these two domains form an extensive interface that is composed of the alpha 4- beta 5- alpha 5 face of the regulatory domain and the C-terminal end of the positioning helix, the trans-activation loop, and the recognition helix of the DNA-binding domain. This domain orientation suggests a mechanism of mutual inhibition by the two domains. Activation of MtrA would require a disruption of this interface to allow the alpha 4- beta 5- alpha 5 face of the regulatory domain to form the intermolecule interactions that are associated with the active state and to allow the recognition helix to interact with DNA. Furthermore, the interface appears to stabilize the inactive conformation of MtrA, potentially reducing the rate of phosphorylation of the N-terminal domain. This combination of effects may form a switch, regulating the activity of MtrA. The domain orientation exhibited by MtrA also provides a rationale for the variation in linker length that is observed within the OmpR/PhoB family of response regulators.

This study examines how well a nonlinear rupture inversion method recovers a set of known dynamic rupture parameters on a synthetic fault based on the 2000 western Tottori, Japan earthquake (M (sub w) 6.6). Rupture evolution on the fault is governed by a slip-weakening friction law. A direct-search method known as the neighborhood algorithm (Sambridge, 1999) is used to find optimal values of both the initial stress distribution and the slip-weakening distance on the fault, based on misfit values between known and predicted strong-motion displacement records. The yield stress and frictional sliding stress on the fault are held constant. A statistical assessment of the results shows that, for this test case, the inversion succeeds in locating all parameters to within + or -14% of their true values. With the model configuration used in this study, the parameters located in the central rupture area are better resolved than the parameters located at the sides and bottom of the fault. In addition, a positive linear correlation between the mean initial stress and the slip-weakening distance is identified. The investigation confirms that dynamic rupture inversion is useful for determining rupture parameters on the fault, but that intrinsic trade-offs and poor resolution of some parameters limit the amount of information that can be unambiguously inferred from the results. In addition, this study demonstrates that using a statistical approach to assess nonlinear inversion results shows how sensitive the misfit measure is to the various parameters, and allows a level of confidence to be attached to the output parameter values.

All but one of the >10 springs occur at the lower contact of the distal olivine-bearing basaltic andesite lavas of the Tuxpan shield, a 0.49- to 0.60-Ma-old cluster of monogenetic scoria cones and lava flows. The Tuxpan shield has a maximum radius of 6 km and was constructed on top of a folded and faulted Cretaceous basement consisting largely of marine limestones, marls, and shales. The mineral waters are characterized by moderate temperatures (28 to 32 degrees ), mild acidity (pH from 5.5 to 6.5), relatively high discharge rates, effervescence of CO (sub 2) gas, clarity at emergence and abundant subsequent precipitation of hydrous iron, silica oxides, and carbonates around pool margins and issuing streamlets. Chemical and isotopic (deuterium, oxygen, and tritium) analyses of water and gas samples obtained during the period 1991-1997 indicate that the springs are largely composed of meteoric water from a local source with relatively short residence times (water ages of 7 to 25 years). Spring waters are chemically characterized by moderate SiO (sub 2) , Ca+Mg nearly equal to Na+K, high HCO (sub 3) , moderate to low Cl, low F and SO (sub 4) , high B, moderate Li, while Br and As are low. In contrast, Fe+Mn is exceptionally high. Thus, the Jungapeo waters cannot be regarded as high-temperature geothermal fluids. Instead, they resemble soda spring waters similar to other low-to-medium temperature soda waters in the world. Gas samples are extremely rich in CO (sub 2) with no detectable geothermal H (sub 2) S or H (sub 2) and very low contents of CH (sub 4) and NH (sub 3) , indicating the gases are not derived from a high-temperature resource. Carbon-13 analyses of CO (sub 2) show a narrow range (-6.7 per mil and -7.2 per mil) that falls within the range for MORB CO (sub 2) . Thus, most CO (sub 2) seems to originate from the mantle but some CO (sub 2) could originate from thermal degradation of organic remains in underlying Cretaceous rocks. (super 3/4) He ratios range from about 2 to 3 Rc/Ra, indicating that a small mantle/magmatic He component is present in the gases. In conclusion, the mineral waters are the surface expression of a low-temperature geothermal system of limited size that originates from the combined effects of a high regional heat flow and (possibly) the remnant heat released from subjacent basaltic andesite magma bodies that constitute the root zone of the Tuxpan shield.

In this study, an experiment-based, high-resolution hydraulic conductivity map offers a test case to evaluate this parameter. Various hydrogeological units are distinguished, each is of irregular shape with distinct heterogeneity pattern created by physical sedimentation. Extending a previous study which used numerical upscaling to compute equivalent conductivities for these units (at two upscaling scales) [Zhang, Y., Gable, C.W., Person, M., 2006. Equivalent hydraulic conductivity of an experimental stratigraphy - implications for basin-scale flow simulations. Water Resources Research 42, W05404. doi:10.1029/2005WR004720], this study compares them with local statistics and effective conductivities predicted by a stochastic theory. Results suggest that for a system with moderate lnK variance (4.07) and low topographic slope ( approximately 1 degrees ), the arithmetic mean (K (sub A) ) provides a good estimate for the maximum principal component (K (sub max) ) of the equivalent conductivity. The minimum principal component (K (sub min) ) lies between the harmonic and geometric means: its closeness to the geometric mean is affected by heterogeneity pattern and upscaling scale. Using K (sub max) (alternatively, the arithmetic mean), geometric mean, and ln(K) variance, the stochastic theory predicts a K (sub min) that is consistent with the up-scaled value. Similarly, knowing K (sub min) , K (sub max) predicted by theory is also consistent with the up-scaled value. For most deposits (some with variance greater than 1), a low-variance version of the theory is more accurate than a high-variance version. However, the increase of topographic slope (to approximately 4 degrees ) and total lnK variance (to 16) result in increased deviation of K (sub max) from K (sub A) . High variance also results in significantly larger anisotropy ratio, possibly due to the dominance of preferential flow. Finally, for select units, equivalent conductivity exhibits scale effect. Field scale representative elementary volume thus does not exist and upscaling the full unit is necessary to obtain the representative conductivity.

The genome consists of a single, circular, 4.43-Mb chromosome containing 3,790 open reading frames, 1,986 of which have been assigned a tentative function. Two of the most striking characteristics of C. hutchinsonii are its rapid gliding motility over surfaces and its contact-dependent digestion of crystalline cellulose. The mechanism of C. hutchinsonii motility is not known, but its genome contains homologs for each of the gld genes that are required for gliding of the distantly related bacteroidete Flavobacterium johnsoniae. Cytophaga-Flavobacterium gliding appears to be novel and does not involve well-studied motility organelles such as flagella or type IV pili. Many genes thought to encode proteins involved in cellulose utilization were identified. These include candidate endo-{szligbeta}-1,4-glucanases and {szligbeta}-glucosidases. Surprisingly, obvious homologs of known cellobiohydrolases were not detected. Since such enzymes are needed for efficient cellulose digestion by well-studied cellulolytic bacteria, C. hutchinsonii either has novel cellobiohydrolases or has an unusual method of cellulose utilization. Genes encoding proteins with cohesin domains, which are characteristic of cellulosomes, were absent, but many proteins predicted to be involved in polysaccharide utilization had putative D5 domains, which are thought to be involved in anchoring proteins to the cell surface.

We are investigating the solubility and speciation of plutonium(VI) carbonate under conditions relevant to natural waters and brines such as those found near some geologic radioactive waste repositories. The solid Pu(VI) phase PuO2CO3(s) was prepared and its solubility was measured in NaCl and NaClO4 solutions in a CO2 atmosphere as a function of pH and ionic strength (0.1-5.6m). The concentration of soluble plutonium in solution was calculated from spectroscopic data and liquid scintillation counting. Spectroscopic measurements also revealed the plutonium oxidation state.

The analysis was carried out by performing three tests with different oxygen concentration on the recuperator where the heat transfer rate is susceptible to fouling, and introducing a correlation for the fouling factor. The comparison of fouling factors obtained with each oxygen level is presented, the relationship between fouling factors and oxygen concentrations is correlated, and the effects of oxidation on heat transfer are demonstrated qualitatively by wetting conditions of the samples.

The complete genome of a model obligate methanol and methylamine utilizer, Methylobacillus flagellatus (strain KT) was sequenced. The genome is represented by a single circular chromosome of approximately 3 Mbp, potentially encoding a total of 2,766 proteins. Based on genome analysis as well as the results from previous genetic and mutational analyses, methylotrophy is enabled by methanol and methylamine dehydrogenases and their specific electron transport chain components, the tetrahydromethanopterin-linked formaldehyde oxidation pathway and the assimilatory and dissimilatory ribulose monophosphate cycles, and by a formate dehydrogenase. Some of the methylotrophy genes are present in more than one (identical or nonidentical) copy. The obligate dependence on single-carbon compounds appears to be due to the incomplete tricarboxylic acid cycle, as no genes potentially encoding alpha-ketoglutarate, malate, or succinate dehydrogenases are identifiable. The genome of M. flagellatus was compared in terms of methylotrophy functions to the previously sequenced genomes of three methylotrophs, Methylobacterium extorquens (an alphaproteobacterium, 7 Mbp), Methylibium petroleiphilum (a betaproteobacterium, 4 Mbp), and Methylococcus capsulatus (a gammaproteobacterium, 3.3 Mbp). Strikingly, metabolically and/or phylogenetically, the methylotrophy functions in M. flagellatus were more similar to those in M. capsulatus and M. extorquens than to the ones in the more closely related M. petroleiphilum species, providing the first genomic evidence for the polyphyletic origin of methylotrophy in BETAPROTEOBACTERIA: JF - Journal of Bacteriology AU - Chistoserdova, Ludmila AU - Lapidus, Alla AU - Han, Cliff AU - Goodwin, Lynne AU - Saunders, Liz AU - Brettin, Tom AU - Tapia, Roxanne AU - Gilna, Paul AU - Lucas, Susan AU - Richardson, Paul M AU - Lidstrom, Mary E AD - University of Washington, Seattle, Washington.

In this paper, we describe a signal processing technique named MIMICRI that may help link motor theory with automatic speech recognition by providing a practical approach to recovering articulator positions from acoustics. MIMICRI's name reflects three important operations it can perform on time-series data: it can reduce the dimensionality of a data set (manifold inference); it can blindly invert nonlinear functions applied to the data (mapping inversion); and it can use temporal context to estimate intermediate data (contextual recovery of information). In order for MIMICRI to work, the signals to be analyzed must be functions of unobservable signals that lie on a linear subspace of the set of all unobservable signals. For example, MIMICRI will typically work if the unobservable signals are band-pass and we know the pass-band, as is the case for articulator motions. We discuss the abilities of MIMICRI as they relate to speech processing applications, particularly as they relate to inverting the mapping from speech articulator positions to acoustics. We then present a mathematical proof that explains why MIMICRI can invert nonlinear functions, which it can do even in some cases in which the mapping from the unobservable variables to the observable variables is many-to-one. Finally, we show that MIMICRI is able to infer accurately the positions of the speech articulators from speech acoustics for vowels. Five parameters estimated by MIMICRI were more linearly related to articulator positions than 128 spectral energies.

These detectors collect counts that are used to determine whether to trigger an alarm. Several candidate alarm rules are evaluated, with attention to background suppression caused by the vehicle. Because the count criterion leads to many nuisance alarms and because background suppression by the vehicle is smaller for ratios of counts, analysis of a ratio criterion is included. Detection probability results that consider the effects of 5 factors are given for 2 signal-injection studies, 1 for counts, and 1 for count ratios.

The breakup of Pangea, the last supercontinent, was accompanied by the emplacement of the largest known continental flood basalt, the Central Atlantic Magmatic Province, which caused massive extinctions at the Triassic-Jurassic boundary (Marzoli et al., 1999). However, there is little support for a plume origin for this catastrophic event (McHone, 2000). On the basis of convection modeling in an internally heated mantle, this paper shows that continental aggregation promotes large-scale melting without requiring the involvement of plumes. When only internal heat sources in the mantle are considered, the formation of a supercontinent causes the enlargement of flow wavelength and a subcontinental increase in temperature as large as 100 degrees C. This temperature increase may lead to large-scale melting without the involvement of plumes. Our results suggest the existence of two distinct types of continental flood basalts, caused by plume or by mantle global warming.

The (super 238) U- (super 230) Th disequilibria measured on separated groundmass phases yield an internal isochron age of 68 ka (+24/-20 ka; 2sigma ). This value cannot be directly compared with surface exposure ages unless erosion rates are known. The apparent (zero erosion) ages determined from both the (super 3) He concentration (47.5+ or -5 ka; 2sigma ) and the (super 36) Cl concentration (41.2+ or -8.8 ka; 2sigma ) are significantly younger than the U-Th isochron age. When minimum estimates of surface erosion based on flow morphology are considered, the (super 3) He concentrations indicate a minimum exposure age of 60 ka, in good agreement with the U-Th isochron age, with a minimum erosion rate of 1.7 mm/k.y. and an erosion rate as high as 5 mm/k.y. in other locations. Correcting for erosion has little effect on the model (super 36) Cl age and, as a result, the (super 36) Cl age is significantly younger than the U-Th isochron age and erosion-corrected (super 3) He ages; this discordance is attributed to a lack of closed-system behavior in the (super 36) Cl system. These new ages have local significance for the geochronology of the Zuni-Bandera volcanic field; however, their larger significance is in their applicability to dating Quaternary basalts and quantifying erosion rates.

Herein, however, the potential for fossil spring deposits to infer water sources and palaeoflowpaths through trace elements and stable and radiogenic isotopes is examined. Past discharge (70 to 285 ka) in the Tecopa Basin in the Death Valley region of southeastern California is represented by tufa deposits, including mounds, pools, cemented ledges and rare calcite feeder veins. delta (super 18) O values indicate that spring discharge was a mixture of far-travelled (regional) water with a significant, and perhaps dominant contribution of local recharge on a nearby range front and alluvial pediment, rather than simply representing an elevated regional water table. delta (super 13) C values indicate regional water had a high TDS, whereas solute data imply low overall solute contents, consistent with dilution by a large component of local recharge. Radiogenic isotope data (U-series, (super 87) Sr/ (super 86) Sr) for tufa indicate that siliciclastic rocks (a regional aquitard) interacted with discharging water. To access this aquitard, regional flow was probably partitioned into a permeable north-south damage zone of a north-south range-bounding fault along the foot of the Resting Spring Range, which ultimately controlled the location of groundwater discharge. Existing models for modern discharge in the Tecopa Basin, by contrast, call upon westward interbasin flow in carbonate rocks from the Spring Mountains through the intervening (and nearly perpendicular) Nopah and Resting Spring Ranges. Understanding the controls on regional groundwater flow is critical in this and other arid regions where water is, by definition, a scarce resource. Thus, although it is a case study, this report highlights a fruitful approach to palaeohydrology that can be widely applied. Abstract Copyright (2007), Wiley Periodicals, Inc. JF - JQS.

The Re/Os ratios of most ureilites show evidence for a recent disturbance, probably related to Re mobility during weathering, and no meaningful chronological information can be extracted from the present data set. The ureilite (super 187) Os/ (super 188) Os ratios span a range from 0.11739 to 0.13018, with an average of 0.1258+ or -0.0023 (1sigma ), similar to typical carbonaceous chondrites, and distinct from ordinary or enstatite chondrites. The similar mean of (super 187) Os/ (super 188) Os measured for the ureilites and carbonaceous chondrites suggests that the ureilite parent body probably formed within the same region of the solar nebula as carbonaceous chondrites. From the narrow range of the (super 187) Os/ (super 188) Os distribution in ureilite meteorites it is further concluded that Re was not significantly fractionated from Os during planetary differentiation and was not lost along with the missing ureilitic melt component. The lack of large Re/Os fractionations requires that Re/Os partitioning was controlled by a metal phase, and thus metal had to be stable throughout the interval of magmatic processing on the ureilite parent body.

AN - 36666732; 3425488 AB - In the context of rising regional instability and conflict, along with increased incidents of global terrorism, in a dynamic, uncertain security environment, emerging nuclear and other weapons of mass destruction threats-both state proliferation and terrorism-are seen as growing dangers giving rise to increasing global insecurity. The international nuclear nonproliferation regime, the centerpiece of which is the Nuclear Non-proliferation Treaty (NPT), is essential to current and future non-proliferation efforts and needs to be maintained and strengthened, not replaced. The normative and legal weight of the regime is important for counterterrorism as well as non-proliferation, but it will not likely directly affect the behaviour of so-called 'rogue states' and terrorists. Preventing them from achieving their objectives if they attempt to wield nuclear and radiological weapons may deter and dissuade them, as may a credible prospect of punishment. The interaction of non-proliferation and deterrence, so clear during the Cold War history of the NPT, remain crucial parts of an increasingly complex picture.

To help understand the biogeochemistry of Mexico City a comprehensive international multi-agency Megacity Initiative: Impact on Regional and Global Environment (MILAGRO) field campaign was conducted in March 2006. We report diurnal and weekly observations of molecular hydrogen, CO, and CO2 in Mexico City. A regular diurnal profile with peak concentrations of hydrogen in early morning caused by the high traffic and shallow boundary layer was revealed. A record level of hydrogen of 5 ppm, a factor of 10 above background levels, was measured. We hypothesize that most of the hydrogen is coming from automobiles. However, we did observe emissions from other industrial or power plant sources. Analysis of the H2/CO, CO/CO2, and H2/CO2 ratios are developed as a chemical fingerprinting method to delineate these sources and relate them to combustion efficiency. We utilize H2/CO ratios to diagnose traffic patterns, for example the early morning H2/CO peak is attributed to sluggish rush our traffic. We also observe significantly (25%) lower hydrogen during the weekend holidays than workdays. Finally, regional scale modeling of the Mexico City hydrogen cycle is performed using the Weather Research Forecast: Chemistry (WRF-CHM) model at 1 km resolution. The model results are compared to our measurements to gain a quantitative understanding of hydrogen sources and sinks in Mexico City. Our findings are significant to the understanding of the global hydrogen cycle and developing an urban baseline for hydrogen to assess potential perturbations to it from transitioning to a hydrogen economy.

While particular aspects of the regional environmental impacts of cities on their surroundings have been thoroughly investigated, e.g., air quality and acid rain, relatively little effort has been focused on the net radiative impact of a megacity on global climate. The range of radiative impacts from a megacity covers many spatial and temporal scales from short-term regional-scale effects due to aerosols and relatively short-lived gases (ozone) to long-term global-scale impacts due to longer-lived trace gases (e.g., carbon dioxide, methane). In this study we combine chemistry- transport model simulations from the Model for Ozone And Related Chemical Tracers (MOZART-2) with in situ and satellite observations from the Aerosol Robotic Network (AERONET) and the Moderate Resolution Imaging Spectroradiometer (MODIS) to calculate the global radiative forcing of megacity emissions. We also explore the radiative impact of various emission control strategies that focus on improving regional air quality. Our results suggest that the warming by greenhouse gases like carbon dioxide and ozone can be moderated or exacerbated by aerosols depending on their optical properties. As the size and number of megacities increase and clean air regulations are implemented, metrics such as the net radiative forcing may become increasingly important in comparing the impact of urban centers and assessing the trade-offs between improving local air quality and minimizing global radiative impacts.

The need for field deployable nucleic acid detection demands inexpensive, facile systems without sacrificing information capacity or sensitivity. Here we describe a novel microarray platform capable of rapid, sensitive nucleic acid detection without specialized instrumentation. The approach is based on a miniaturized lateral flow device that makes use of hybridization-mediated target capture. The miniaturization of lateral flow nucleic acid detection provides multiple advantages over traditional lateral flow devices. Ten-microliter sample volumes reduce reagent consumption and yield analyte detection times, excluding sample preparation and amplification, of <120 s while providing sub-femtomole sensitivity. Moreover, the use of microarray technology increases the potential information capacity of lateral flow. Coupled with a hybridization-based detection scheme, the lateral flow microarray (LFM) enables sequence-specific detection, opening the door to highly multiplexed implementations for broad-range assays well suited for point-of-care and other field applications. The LFM system is demonstrated using an isothermal amplification strategy for detection of Bacillus anthracis, the etiologic agent of anthrax. RNA from as few as two B. anthracis cells was detected without thermocycling hardware or fluorescence detection systems.

The optical properties are related to chemical composition, size distribution, and morphology, which also have implications for human health and environmental degradation. During the MILAGRO field campaign, we measured ensemble aerosol absorption and angle-integrated scattering in Mexico City. These measurements were performed using the Los Alamos aerosol photoacoustic instrument with an integrated nephelometer (LAPA) operating at 781 nm. The LAPA was mounted on-board the Aerodyne Inc. mobile laboratory, which hosted a wide variety of gaseous and aerosol instruments. During the campaign, the Aerodyne mobile laboratory was moved to different sites, capturing the influence of spatial and temporal parameters including location, aging, elevation, and sources on ambient air pollution. The LAPA operated almost continuously between the 3rd and the 28th of March 2006. During the same period we collected ambient aerosols on more than 100 Nuclepore filters for scanning electron microscopy (SEM) analysis. Filter samples were collected during specific pollution events and different times of the day. Subsequently, SEM images of selected filters were taken to study particle morphology. The elemental composition of a few individual particles was also qualitatively assessed by energy dispersive X-ray spectroscopy. Between March 7th and 19th the laboratory was sampling air close to the top of the Pico Tres Padres, a similar to 3000 m high mountain on the north side of the Mexico City. Daily changes of aerosol loading and pollutant concentrations followed the expected diurnal variations of the boundary layer height. Here we report a preliminary analysis of aerosol absorption, scattering, and morphology at Pico Tres Padres for three specific days (9th, 11th and 12th of March 2006). The single scattering albedo (ratio of scattering to total extinction) during these three days showed a characteristic drop in the tens-of-minutes-to-hour time frame immediately following the growth of the boundary layer above the sampling site. Later in the day the single scattering albedo grew steadily to reach a maximum in the late afternoon. The SEM images show a wide variety of aerosol shapes including fractal-like chain aggregates (possibly soot), spherical particles (possibly tar balls), cylinders, and irregular non-fractal shapes. The increased afternoon single scattering albedo in the hottest part of the day qualitatively correlated with a relative increase in spherical particles that typically are not strongly light absorbing relative to fractal- like chain aggregates that are typically strongly light absorbing. These changes in optical properties and/or morphology can be explained by multiple mechanisms such as the collapse of fractal-like chain aggregates due to thermal effects and/or condensation of volatile compounds, coating by organic compounds, and photochemical secondary organic particle formation. Elemental analysis of a few individual particles yielded a relative large carbon abundance combined with smaller fractions of oxygen, silicon, metals, and other elements.

The US. Department of Energy has no uniform requirements for packaging and storage of nuclear materials other than those declared excess and packaged to DOE-STD-3013-2000. This report describes a methodology for prioritizing a large inventory of nuclear material containers so that the highest risk containers are repackaged first. The methodology utilizes expert judgment to assign respirable fractions and reactivity factors to accountable levels of nuclear material at Los Alamos National Laboratory. A relative risk factor is assigned to each nuclear material container based on a calculated dose to a worker due to a failed container barrier and a calculated probability of container failure based on material reactivity and container age. This risk-based methodology is being applied at LANL to repackage the highest risk materials first and, thus, accelerate the reduction of risk to nuclear material handlers.

AN - 70555601; 17533826 AB - We identify water-soluble (23 degrees C) crude oil NSO nonvolatile acidic, basic, and neutral crude oil hydrocarbons by negative-ion ESI and continuous flow FD FT-ICR MS at an average mass resolving power, m/deltam50% = 550,000. Of the 7000+ singly charged acidic species identified in South American crude oil, surprisingly, many are water-soluble, and much more so in pure water than in seawater. The truncated m/z distributions for water-soluble components exhibit preferential molecular weight, size, and heteroatom class influences on hydrocarbon solubility. Acidic water-soluble heteroatomic classes detected at >1% relative abundance include O, O2, O3, O4, OS, O2S, O3S, O4S, NO2, NO3, and NO4. Parent oil class abundance does not directly relate to abundance in the water-soluble fraction. Acidic oxygen-containing classes are most prevalent in the water-solubles, whereas acidic nitrogen-containing species are least soluble. In contrast to acidic nitrogen-containing heteroatomic classes, basic nitrogen classes are water-soluble. Water-soluble heteroatomic basic classes detected at >1% relative abundance include N, NO, NO2, NS, NS2, NOS, NO2S, N2, N2O, N2O2, OS, O2S, and O2S2.

AN - 70363870; 17225213 AB - Our objectives are to quickly interpret symptoms of emergency patients to identify likely syndromes and to improve population-wide disease outbreak detection. We constructed a database of 248 syndromes, each syndrome having an estimated probability of producing any of 85 symptoms, with some two-way, three-way, and five-way probabilities reflecting correlations among symptoms. Using these multi-way probabilities in conjunction with an iterative proportional fitting algorithm allows estimation of full conditional probabilities. Combining these conditional probabilities with misdiagnosis error rates and incidence rates via Bayes theorem, the probability of each syndrome is estimated. We tested a prototype of computer-aided differential diagnosis (CADDY) on simulated data and on more than 100 real cases, including West Nile Virus, Q fever, SARS, anthrax, plague, tularaemia and toxic shock cases. We conclude that: (1) it is important to determine whether the unrecorded positive status of a symptom means that the status is negative or that the status is unknown; (2) inclusion of misdiagnosis error rates produces more realistic results; (3) the naive Bayes classifier, which assumes all symptoms behave independently, is slightly outperformed by CADDY, which includes available multi-symptom information on correlations; as more information regarding symptom correlations becomes available, the advantage of CADDY over the naive Bayes classifier should increase; (4) overlooking low-probability, high-consequence events is less likely if the standard output summary is augmented with a list of rare syndromes that are consistent with observed symptoms, and (5) accumulating patient-level probabilities across a larger population can aid in biosurveillance for disease outbreaks.

Seismic energy of this event was recorded at three nearby seismometers. The origin time of the explosion was determined by analyzing the Rayleigh waves and found to be 06h55m27+ or -2sec coordinated universal time (UTC). Ground truth of the explosion was invoked to assess the accuracy of the location derived from infrasound data recorded over Western Europe. Different infrasonic phases were identified by using array-processing techniques and raytracing through atmospheric models. The analysis showed that the derived location was situated 13 km from the true location. The total area of the uncertainty ellipse, or area to be searched if the source was of unknown origin, was 690 km (super 2) . After the origin time and location, the yield was calculated by comparing infrasonic stratospheric amplitudes with those from a high-explosives dataset and was estimated at 40.9 tons high- explosives equivalent. In summary, this study illustrates the capability of seismic and infrasound data in forensic investigations. Furthermore, the potential of infrasound as a monitoring or verification technique is addressed.

The core was investigated as part of a program to evaluate the integrity of Portland-cement based wellbore systems in CO sub(2)-sequestration environments. The recovered cement had air permeabilities in the tenth of a milliDarcy range and thus retained its capacity to prevent significant flow of CO sub(2). There was evidence, however, for CO sub(2) migration along both the casing-cement and cement-shale interfaces. A 0.1-0.3 cm thick carbonate precipitate occurs adjacent to the casing. The CO sub(2) producing this deposit may have traveled up the casing wall or may have infiltrated through the casing threads or points of corrosion. The cement in contact with the shale (0.1-1 cm thick) was heavily carbonated to an assemblage of calcite, aragonite, vaterite, and amorphous alumino-silica residue and was transformed to a distinctive orange color. The CO sub(2) causing this reaction originated by migration along the cement-shale interface where the presence of shale fragments (filter cake) may have provided a fluid pathway. The integrity of the casing-cement and cement-shale interfaces appears to be the most important issue in the performance of wellbore systems in a CO sub(2) sequestration reservoir.

For these materials applications, radiation damage and relatively large amounts of helium generated during the irradiation damage process are recognized to be major issues with materials durability and performance. In these cases, irradiation damage alone is significant; however the added effect of helium on the accumulation of defects and defect clusters can dramatically imact the effect of the resulting microstructure on physical and mechanical properties. Using a kinetic Monte Carlo method we study embryonic bubble nucleation under irradiation damage conditions and helium generation. Migration of helium, vacancies, self interstitial atoms and their clusters is included in the kinetic Monte Carlo model. We estimate embryonic bubble density, interstitial cluster density and embryonic bubble size as a function of the helium content and displacements per atom. Bubble density and size increases with increasing helium content; there is a slight increase in interstitial cluster density as well.

The electrical resistivity of the plateau ranged over three orders of magnitude ( 2000 Omega m) to a depth of at least 300 m. Borehole and surface-derived data allow the correlation of resistivity images with the hydrogeology of the plateau. As expected, water exerts a significant control on resistivity. However, the presence of large amounts (up to 90%) of clay in some units, in conjunction with water, also has a significant effect, lowering resistivity (to less than or equal to 30 Omega m) more than the presence of clay-free saturated zones alone. Because of the resulting low resistivity, we are able to better delineate a large, known volume of clay-altered volcaniclastic rock and postulate the presence of another. Resistivity values of 100-300 mu m correlate with depths to saturated zones where no clay is present, but they do not allow us to distinguish between one large or several smaller perched groundwater zones and the underlying regional zone of saturation. We imaged a region of significant infiltration related to a sewage treatment plant and to near-surface hydrogeologic conditions conducive to infiltration and correlated with a region of preferential transport of anthropogenic chemicals through the vadose zone. AEM data provide an important synoptic view of the shallow (few hundred meters) resistivity structure of the plateau. Although interpretation of the data is not unique, when combined with borehole geologic, hydrologic, and geo-chemical data, it can provide relative depths to saturated zones, delineate regions of high clay content (zones of alteration), and image regions of recharge to the regional aquifer.

Cities have long been known to be society's predominant engine of innovation and wealth creation, yet they are also its main source of crime, pollution, and disease. The inexorable trend toward urbanization worldwide presents an urgent challenge for developing a predictive, quantitative theory of urban organization and sustainable development. Here we present empirical evidence indicating that the processes relating urbanization to economic development and knowledge creation are very general, being shared by all cities belonging to the same urban system and sustained across different nations and times. Many diverse properties of cities from patent production and personal income to electrical cable length are shown to be power law functions of population size with scaling exponents, beta , that fall into distinct universality classes. Quantities reflecting wealth creation and innovation have beta approximately 1.2 >1 (increasing returns), whereas those accounting for infrastructure display beta approximately 0.8 <1 (economies of scale). We predict that the pace of social life in the city increases with population size, in quantitative agreement with data, and we discuss how cities are similar to, and differ from, biological organisms, for which beta <1. Finally, we explore possible consequences of these scaling relations by deriving growth equations, which quantify the dramatic difference between growth fueled by innovation versus that driven by economies of scale. This difference suggests that, as population grows, major innovation cycles must be generated at a continually accelerating rate to sustain growth and avoid stagnation or collapse.

Implantation fluences from 1.5 to 10x10 super(1) super(6)atoms/cm super(2) were used to control the average size of the nanoparticles. Transmission electron microscopy measurements revealed sizes ranging from ca. 2.5 to 10nm, depending on the implantation fluence. The magnetic properties were determined using a superconducting quantum interference device, with measurements carried out as a function of temperature and applied magnetic field. The results show that magnetic properties are dependent on the dimensions of the nanoparticles, with an increase of the blocking temperature, anisotropy constant, and relative remanent magnetization, and a decrease of the saturation magnetization field decreasing for larger particles.

The crystallization age of LAP 02205 is most precisely dated by an internal Rb-Sr isochron of 2991+ or -14 Ma, with an initial (super 87) Sr/ (super 88) Sr at the time of crystallization of 0.699836+ or -0.000010. Leachable REE-rich phosphate phases of LAP 02205 do not plot on a Sm-Nd mineral isochron, indicating contamination or open system behavior of the phosphates. Excluding anomalous phases from the calculation of a Sm-Nd isochron yields a crystallization age of 2992+ or -85 (initial epsilon (super 143) Nd=+2.9+ or -0.8) that is within error of the Rb-Sr age, and in agreement with other independent age determinations for LAP 02205 from Ar-Ar and U-Pb methods. The calculated (super 147) Sm/ (super 144) Nd source ratios for LAP 02205, various Apollo 12 and 15 basalts, and samples with strong affinities to KREEP (SaU 169, NWA 773, 15386) are uncorrelated with their crystallization ages. This finding does not support the involvement of a common KREEP component as a heat source for lunar melting events that occurred after crystallization of the lunar magma ocean.

2007-123671 AB - The approximately 80 ka Lathrop Wells volcano (southern Nevada, U.S.A.) preserves evidence for a range of explosive processes and emplacement mechanisms of pyroclastic deposits and lava fields in a small-volume basaltic center. Early cone building by Strombolian bursts was accompanied by development of a fan-like lava field reaching approximately 800 m distance from the cone, built upon a gently sloping surface. Lava flows carried rafts of cone deposits, which provide indirect evidence for cone facies in lieu of direct exposures in the active quarry. Subsequent activity was of a violent Strombolian nature, with many episodes of sustained eruption columns up to a few km in height. These deposited layers of scoria lapilli and ash in different directions depending upon wind direction at the time of a given episode, reaching up to approximately 20 km from the vent, and also produced the bulk of the scoria cone. Lava effusion migrated from south to north around the eastern base of the cone as accumulation of lavas successively reversed the topography at the base of the cone. Late lavas were emplaced during violent Strombolian activity and continued for some time after explosive eruptions had waned. Volumes of the eruptive products are: fallout--0.07 km (super 3) , scoria cone--0.02 km (super 3) , and lavas--0.03 km (super 3) . Shallow-derived xenolith concentrations suggest an upper bound on average conduit diameter of approximately 21 m in the uppermost 335 m beneath the volcano. The volcano was constructed over a period of at least seven months with cone building occurring only during part of that time, based upon analogy with historical eruptions. Post-eruptive geomorphic evolution varied for the three main surface types that were produced by volcanic activity: (1) scoria cone, (2) low relief surfaces (including lavas) with abundant pyroclastic material, and (3) lavas with little pyroclastic material. The role of these different initial textures must be accounted for in estimating relative ages of volcanic surfaces, and failure to account for this resulted in previous erroneous interpretation that the volcano's activity was polycyclic (eruptions separated by 1000s-10,000s of years). Lathrop Wells volcano provides an example of the wide range of eruptive processes that can occur with little change in major element composition; the variation in explosive and effusive processes, including their simultaneous occurrence, must result entirely from fluid dynamic, crystallization, and degassing processes in the ascending multiphase magma. The volcano also provides key analog information regarding processes that are important for volcanic risk assessment at the proposed Yucca Mountain radioactive waste repository, approximately 18 km north of the volcano.

Despite the utility of these two isotopes in providing time-signatures for fluid end-members, considerable uncertainty remains regarding the interpretation of "intermediate-age" waters in hydrologic systems. These waters are likely the result of the combination of two or more halogen sources at some time in the past, each with its own characteristic concentration and isotopic composition. In order to unravel the evolution of these "intermediate-age" waters, the effect that infiltration of meteoric water has on the isotopic composition of older formation waters is modeled. Also evaluated is the effect that the timing of dilution has on (super 129) I and (super 36) Cl signatures observed in the present, specifically, the hypothesis that halogen isotopic signatures imparted by the mixing of brine and meteoric waters early in the development of a sedimentary basin are quantitatively different from those imparted by the mixing of old brines with recent meteoric waters. The modeled results are compared to previously published isotopic data from production wells in the Fruitland Formation coalbed methane system. Portions of the basin preserve enough of the original brine source to retain (super 129) I/I ratios roughly recording the age of deposition of organic matter (73-76 Ma) even where some degree of dilution by meteoric water has occurred. However, the (super 129) I signatures of waters that presently contain less than 10% of the original formation water component indicate that mixing has occurred within the past 10 Ma, consistent with recently published (super 4) He data. Both (super 36) Cl concentrations and (super 36) Cl/Cl ratios show that waters containing more than 10% formation water are all in secular equilibrium with the host formation coals. In contrast, waters with less than 1% of the original formation water's Cl (super -) content all have (super 36) Cl/Cl ratios which are greater than secular equilibrium values, indicating the migration of meteoric water into the coal formation more recently than 2 Ma.

Pathogenic strains of H. somnus are a significant cause of systemic disease in cattle. We report the genome sequence of H. somnus 129Pt, a nonpathogenic commensal preputial isolate, and the results of a genome-wide comparative analysis of H. somnus 129Pt, Haemophilus influenzae Rd, and Haemophilus ducreyi 35000HP. We found unique genes in H. somnus 129Pt involved in lipooligosaccharide biosynthesis, carbohydrate uptake and metabolism, cation transport, amino acid metabolism, ubiquinone and menaquinone biosynthesis, cell surface adhesion, biosynthesis of cofactors, energy metabolism, and electron transport. There were also many genes in common among the three organisms. Our comparative analyses of H. somnus 129Pt, H. influenzae Rd, and H. ducreyi 35000HP revealed similarities and differences in the numbers and compositions of genes involved in metabolism, host colonization, and persistence. These results lay a foundation for research on the host specificities and niche preferences of these organisms. Future comparisons between H. somnus 129Pt and virulent strains will aid in the development of protective strategies and vaccines to protect cattle against H. somnus disease.

The resulting global dimethyl sulfide simulation framework was then subjected to variation in plant cell precursor content and the kinetic form of removal terms. Chi square type merit minima were computed analytically along a release rate axis over global, low latitude and localized domains. A band of width 60 degrees centered on the equator proved to be the most effective optimization area because it greatly exceeded resolution of the validation data set but avoided fronts where the driver ecodynamics module overpredicts chlorophyll. Loss terms involving bacterial consumption formulated as bimolecular kinetics and photochemical decay sensitized by dissolved organic matter independently provided superior agreement with data by modulating peaks along the equatorial divergence. Factor of ten reductions in the sulfur precursor content of diatoms or small noncalcite secretors respectively flattened and exaggerated the same features, but intermediate compositions were not tested. The parameter suite of constant intracellular sulfur, second order osmotrophy (microbial uptake) and photochemistry set proportional to photosynthetic radiation is recommended and packaged as a startup mechanism. This particular combination optimizes large-scale reduced sulfur fields across well-understood ecosystems while simultaneously maintaining parsimony. Visualizations from the inverse procedure are offered for multiple mechanisms, as mappings of both normalized deviation and concentration. The value of the rate constant for injection from plant and animal material was often determined to be of the order weeks, consistent with emission via grazing or aging/mortality. Refinement of the model will require linkage to the ecological flows associated with cell disruption, accounting of elemental metabolic stresses which in part govern reduced sulfur storage, addition of true microbial ecology, further studies of open ocean sulfur photochemistry and longer duration/more detailed optimization exercises. A stepwise strategy is outlined for moving through this task list. In next-generation experiments it may prove expedient to fix sulfur content ratios within taxonomic classes while varying the maximum cell content.

AN - 68930274; 17114256 AB - Clostridium botulinum is a taxonomic designation for many diverse anaerobic spore-forming rod-shaped bacteria that have the common property of producing botulinum neurotoxins (BoNTs). The BoNTs are exoneurotoxins that can cause severe paralysis and death in humans and other animal species. A collection of 174 C. botulinum strains was examined by amplified fragment length polymorphism (AFLP) analysis and by sequencing of the 16S rRNA gene and BoNT genes to examine the genetic diversity within this species. This collection contained representatives of each of the seven different serotypes of botulinum neurotoxins (BoNT/A to BoNT/G). Analysis of the16S rRNA gene sequences confirmed previous identifications of at least four distinct genomic backgrounds (groups I to IV), each of which has independently acquired one or more BoNT genes through horizontal gene transfer. AFLP analysis provided higher resolution and could be used to further subdivide the four groups into subgroups. Sequencing of the BoNT genes from multiple strains of serotypes A, B, and E confirmed significant sequence variation within each serotype. Four distinct lineages within each of the BoNT A and B serotypes and five distinct lineages of serotype E strains were identified. The nucleotide sequences of the seven toxin genes of the serotypes were compared and showed various degrees of interrelatedness and recombination, as was previously noted for the nontoxic nonhemagglutinin gene, which is linked to the BoNT gene. These analyses contribute to the understanding of the evolution and phylogeny within this species and assist in the development of improved diagnostics and therapeutics for the treatment of botulism.

Since the expected initial speed of the body was about 12.9 km/s, a four-element ground-based infrasound array was deployed to Wendover, Nevada, USA, to measure the hypersonic booms from the re-entry. At a distance of approximately 33 km from the nominal trajectory, we easily recorded the weak acoustic arrivals and their continued rumbling after the main hypersonic boom arrival. In this paper, we report on subsequent analyses of these data, including an assessment of the expected entry characteristics (dynamics, energetics, ablation and panchromatic luminosity, etc.) on the basis of a bolide/meteor/fireball entry model that was specifically adapted for modeling a re-entering man-made object. Throughout the infrasonic data analyses, we compared our results for Stardust to those previously obtained for Genesis. From the associated entry parameters, we were also able to compute the kinetic energy density conservation properties for the propagating line source blast wave and compared the inviscid theoretical predictions against observed ground-based infrasound amplitude and wave period data as a function of range. Finally, we made a top-down bottom-up assessment of the line source wave normals propagating downward into the complex temperature/sound speed and horizontal wind speed environment during January 15,2006. This assessment proved to be generally consistent with the signal processing analysis and with the observed time delay between the known Stardust entry and the time of observations of infrasound signals, and so forth.

Ash content of sediment layers is estimated using fallout (super 137) Cs as a tracer, and ash concentrations are shown to rapidly decrease through a series of moderate-intensity convective storms in the first rainy season after the fire. Over 90% of the ash was delivered to the reservoir in the first year, and ash concentrations in suspended sediment were negligible after the second year. Delivery of the remainder of the fine sediment also declined rapidly after the first year despite the occurrence of higher-intensity storms in the second year. Fine sediment loads after five years remained significantly above prefire averages. Deposition of coarse-grained sediment was irregular in time and was associated with transport by snowmelt runoff of sediment stored along the upstream channel during short-duration summer floods. Coarse sediment delivery in the first four years was strongly correlated with snowmelt volume, suggesting a transport-limited system with abundant available sediment. Transport rates of coarse sediment declined in the fifth year, consistent with a transition to a more stable channel as the accessible sediment supply was depleted and the channel bed coarsened. Maximum impacts from ash and other fine-grained sediment therefore occurred soon after the fire, whereas the downstream impacts from coarse-grained sediment were attenuated by the more gradual process of bedload sediment transport.

Two bacteriophages, MS-2 and PRD-1, were used as surrogates for human pathogenic enteric viruses during two tracer tests. A vacuum manifold was used to simulate the drainage effects of an underlying unsaturated soil profile, allowing for the collection of percolate samples at 4cm immediately below the infiltrative surface. The impact of effluent applied (septic tank effluent (STE) or a simulated ground water), soil type (medium sand or sandy loam), hydraulic loading rate (5 or 25cm/day) and method of application (four equivalent daily doses or 24 equivalent micro-doses per day) on the removal of viruses were investigated. These unsaturated mini column experiments demonstrated that the removal of viruses within an infiltrative surface zone (of 4cm) generally improved over time under the conditions studied. An exception occurred in sand-filled columns dosed with STE where the removal of PRD-1 decreased after a period of effluent application. Statistical analysis conducted on the calculated percent removal demonstrated that the quality of the effluent applied to the infiltrative surface is important for removal of MS-2 and PRD-1. Hydraulic loading rate also proved important in the removal of viruses. At the time of tracer test 2, columns dosed at the higher HLR (25cm/day) had higher percent removals for both MS-2 and PRD-1. Soil type altered the removal of PRD-1 at the time of the second tracer test, at which time sandy loam had higher removal rates for PRD-1. No significant differences were observed between columns dosed four times daily and those dosed 24 times daily for either bacteriophage at either of the tracer test time points. These data suggest that over a relatively short period of operation the infiltrative surface of soil based wastewater treatment systems can achieve much higher removal then initially measured shortly after startup.

In this paper we describe the first application of consensus engineering to the ab initio creation of a novel fluorescent protein. This was based on the alignment of 31 fluorescent proteins with >62% homology to monomeric Azami green (mAG) protein, and used the sequence of mAG to guide amino acid selection at positions of ambiguity. This consensus green protein is extremely well expressed, monomeric and fluorescent with red shifted absorption and emission characteristics compared to mAG. Although slightly less stable than mAG, it is better expressed and brighter under the excitation conditions typically used in single molecule fluorescence spectroscopy or confocal microscopy. This study illustrates the power of consensus engineering to create stable proteins using the subtle information embedded in the alignment of similar proteins and shows that the benefits of this approach may extend beyond stability.

AN - 70153963; 17766257 AB - One of the challenges to the dose assessment team in response to an inhalation incident in the workplace is to provide the occupational physicians, operational radiation protection personnel and line managers with early estimates of radionuclide intakes so that appropriate consequence management and mitigation can be done. For radionuclides such as Pu, where in vivo counting is not adequately sensitive, other techniques such as the measurement of removable radionuclide from the nasal airway passages can be used. At Los Alamos National Laboratory (LANL), nose swabs of the ET1 region have been used routinely as a first response to airborne Pu releases in the workplace, as well as for other radionuclides. This paper presents the results of analysing over 15 years of nose swab data, comparing these with dose assessments performed using the Bayesian methods developed at LANL. The results provide empirical support for using nose swab data for early dose assessments. For Pu, a rule of thumb is a dose factor of 0.8 mSv Bq(-1), assuming a linear relationship between nasal swab activity and committed effective dose equivalent. However, this value is specific to the methods and models used at LANL, and should not be applied directly without considering possible differences in measurement and calculation methods.

AN - 70143412; 17623684 AB - Workers are routinely monitored by urinalysis for exposure to uranium at Los Alamos National Laboratory. Urine samples are analysed by alpha spectroscopy for 234U, 235U and 238U. Interpretation of the data is complicated by the presence of natural uranium in the workers' drinking water and diet. Earlier methods used drinking water samples to estimate the dietary component in urine excretion. However, there proved to be insufficient correlation between drinking water concentration and excretion rate. Instead, an iterative calculation is used to identify a typical excretion rate for each individual in the absence of occupational intakes. Bayesian dose-assessment methods, first developed for plutonium bioassay at Los Alamos, have been adapted for uranium. These methods, coupled with an algorithm for identifying each individual's baseline level of uranium from environmental sources, yield improved reliability in the identification of occupational intakes.

AN - 70140678; 17766261 AB - Because of the lack of existing information needed to evaluate the risks from inhalation exposures to depleted uranium (DU) aerosols of US soldiers during the 1991 Persian Gulf War, the US Department of Defense funded an experimental study to measure the characteristics of DU aerosols created when Abrams tanks and Bradley fighting vehicles are struck with large-caliber DU penetrators, and a dose and risk assessment for individuals present in such vehicles. This paper describes some of the difficulties experienced in dose assessment modelling of the very complex DU aerosols created in the Capstone studies, e.g. high concentrations, heterogeneous aerosol properties, non-lognormal particle size distributions, triphasic in vitro dissolution and rapid time-varying functions of both DU air concentration and particle size. The approaches used to solve these problems along with example results are presented.

AN - 70138855; 17766262 AB - The US National Council on Radiation Protection and Measurements, in collaboration with the International Commission on Radiological Protection, has been developing a biokinetic and dosimetric model for radionuclide-contaminated wounds. The finalised model is described briefly in this paper, together with the scientific basis and application. The multicompartment model uses first-order linear biokinetics to describe the retention and clearance of a radionuclide deposited in a wound site using seven default retention categories. Examples using plutonium nitrate in colloidal form and uranium in metal fragments show the behaviour of the less soluble forms of radionuclides in wounds, in which long-term retention is predicted. Using uranium as an example, the wound model is coupled to a uranium International Commission on Radiological Protection systemic model to predict urinary excretion patterns for different physicochemical forms of uranium. The latter application is needed for bioassay interpretation.
