TY - JOUR T1 - Late Pleistocene-Holocene oceanographic variability in the Okhotsk Sea; geochemical, lithological and paleontological evidence AN - 51332501; 2004-061334 AB - Sedimentary, geochemical and paleontological data, extracted from a sediment core taken from the central Okhotsk Sea, record climatic and sedimentary changes over the past 100 ky. Benthic foraminiferal oxygen isotope record and accelerator mass spectrometry (AMS) (super 14) C data provide the basis for the core age chronology. Planktonic and benthic foraminiferal delta (super 18) O and delta (super 13) C measurements, magnetic susceptibility, ice rafted debris and coarse fraction content, carbonate and organic carbon content, and diatom and pollen spectra show major changes in regional climate, sea surface conditions, ice extent and sedimentary regime, which are correlated with the global glacial-interglacial changes of marine isotope stages (MIS) 1 through 5.3. Regional cooling and intensification of winter sea ice formation during the last glaciation increased the northern shelf surface water density and Sea of Okhotsk Intermediate Water (SOIW) formation. In addition to major Milankovitch-scale changes, lithological, geochemical and paleontological indices also show suborbital oscillations in Okhotsk Sea hydrology, sedimentation and regional climate. These shorter-term oscillations are characterized by coupled maxima in ice rafted debris and sediment coarse fraction (lithodynamic indices, LDI) values, and most are associated with cold events involving enhanced winter ice formation and intensification of SOIW and North Pacific intermediate water (NPIW) formation. The terminations of LDI maxima were induced by climate warming and reductions in ice formation and were accompanied by sharp decreases in planktonic foraminiferal delta (super 18) O. During the glacial terminations of MIS 2 and 4, however, the onset of suborbital-scale LDI maxima occurs close to sharp negative delta (super 18) O shifts in planktonic foraminifera (delta (super 18) Opf) associated with climate warming. In these special cases, the LDI maxima occurred under warm climate and rising sea levels and did not lead to increases in SOIW or NPIW ventilation.

The SIA system interfaced aerosol sampling with multiplexed microsphere immunoassay-flow cytometric detection. Metering and sequestering of microspheres using SIA was found to be reproducible and reliable, over 24-h periods of autonomous operation. Four inbuilt immunoassay controls showed excellent immunoassay and system stability over five days of unattended continuous operation. Titration curves for two biological warfare agents, Bacillus anthracis and Yersinia pestis, obtained using the automated SIA procedure were shown to be similar to those generated using a manual microtiter plate procedure.

However, the physical mechanism by which magnesium alters the external form of calcite has remained controversial due to a lack of direct experimental insight. Here we use in situ AFM observations of step dynamics and growth-hillock morphology to resolve the role of Mg (super 2+) in governing calcite surface morphologies. We show that Mg (super 2+) directly modifies the surface morphology of calcite as a consequence of differential interaction with four crystallographically controlled step directions. Step-specific interactions are especially evident at low Mg/Ca ratios in solution, where steps with acute step-edge geometries ([441]- and [481]-) are observed to be rough while obtuse steps ([441]+ and [481]+) remain smooth. Higher Mg/Ca solution ratios cause the edges of both step-types to become rough and the growth spiral to approach an elliptical form. During this process, new [421] step directions are generated by decreased growth velocities at the intersection of the + or - directions. As these steps flow along the [010] vector, they accumulate and result in the formation of pseudofacets with an orientation that approximates a (010) face. We propose that this phenomenon is the result of strain at the intersection of nonequivalent step-types, resulting in differential Mg (super 2+) incorporation across the boundary between those steps. This hypothesis is supported by estimates of the incorporated strain as well as observations of growth-hillock recovery from impurity poisoning that indicate the presence of "remembered" strain at the boundary of the nonequivalent step-types. The results of this study offer a plausible molecular-scale explanation for elongate calcite crystals that are commonly observed in sedimentary environments. This novel explanation for habit modification of calcite by impurities arises from step-specific impurity interactions rather than the face-specific interactions commonly assumed in previous models (Folk 1974; Lahann 1978).

The interpretation of these seismological models in terms of chemical composition and temperature thus relies on the knowledge of the chemical composition, structure and elastic properties of some candidate materials relevant to geophysics. We will describe some recent advances in experimental mineral physics which yield essential information on the elastic properties of pertinent materials of Earth's mantle and core. In particular, we show that inelastic X-ray scattering (IXS) proves to be a well suited spectroscopic technique for the study of phonon dispersion in materials under high pressure. Inelastic scattering experiments carried out on polycrystalline samples provide measurements of orientationally averaged longitudinal acoustic velocities whereas investigations on single crystals yield elastic moduli. Such a technique is thus highly interesting for mineral physicists and offers a great potential in providing essential elastic data and their pressure and/or temperature dependence on most compounds of geophysical interest.

Phospholipid fatty acid analysis revealed that approximately 104-105 viable cells per gram of dry rock are extant, and water availability was shown to be the primary factor limiting microbial growth in situ. Phosphate and carbon limitation, however, also suppress final cell densities by at least one order of magnitude under saturated conditions. Despite these limiting factors, significant growth of aerobic chemoheterotrophic microorganisms was shown to occur in unconcentrated simulated groundwater with or without addition of a reduced carbon source (7 x 10 super(7) and 8 x 10 super(6) planktonic cells/mL, respectively), indicating that when water becomes available in the repository environment, microbial growth will ensue. Organisms that were isolated from stationary cultures grown from Yucca Mountain rock in concentrated and unconcentrated simulated groundwaters showed significant 16S rDNA sequence divergence from reference organisms. Different (but related) organisms were isolated from concentrated and unconcentrated groundwater-grown cultures. Generally, as experimental conditions approached those expected to be encountered in situ, the organisms isolated were more divergent from reference organisms. Organisms that were isolated have metabolic properties that could allow them to be active and grow within the repository environment if water availability is sufficient.

One solution is to study the gene expressed at a single ectopic site in cis. We have designed and constructed a vector that allows homologous recombination into a gene encoding a frame-shifted IS1016-V6 protein in the Haemophilus influenzae Rd KW20 chromosome (HI1018). This site is the location of the 35 kilobase capsule locus in encapsulated type b and d strains. This locus is not present in the nontypeable Rd KW20 strain, thus allowing ectopic expression of genes homologously recombined into HI1018 without polar effects.

AN - 71947601; 15152935 AB - A new radiation phantom with humanoid shape and adjustable thickness (RPHAT) has been developed. Unlike the RANDO phantom which is a fixed thickness, this newly designed phantom has adjustable thickness to address the range of thicknesses of real-world patients. RPHAT allows adjustment of the body thickness by being sliced in the coronal (instead of axial) direction. Centre slices are designed so that more sections can be added or removed while maintaining the anthropomorphic shape. A prototype of the new phantom has been successfully used in a study investigating peripheral dose delivery, where the amount of scatter within the patient, and therefore the patient thickness, plays a critical role in dose deposition. This newly designed phantom is an important tool to improve the quality of radiation therapy.

The light chains of BoNTs are unique zinc proteases that have stringent substrate specificity and require exceptionally long substrates. We have determined the crystal structure of the protease domain from BoNT serotype A (BoNT/A). The structure reveals a homodimer in a product-bound state, with loop F242-V257 from each monomer deeply buried in its partner's catalytic site. The loop, which acts as a substrate, is oriented in reverse of the canonical direction for other zinc proteases. The Y249-Y250 peptide bond of the substrate loop is hydrolyzed, leaving the Y249 product carboxylate coordinated to the catalytic zinc. From the crystal structure of the BoNT/A protease, detailed models of noncanonical binding and proteolysis can be derived which we propose are also consistent with BoNT/A binding and proteolysis of natural substrate synaptosome-associated protein of 25 kDa (SNAP-25). The proposed BoNT/A substrate-binding mode and catalytic mechanism are markedly different from those previously proposed for the BoNT serotype B.

AN - 71902930; 14735274 AB - Direct measurement of tritium atoms by accelerator mass spectrometry (AMS) enables rapid low-activity tritium measurements from milligram-sized samples and permits greater ease of sample collection, faster throughput, and increased spatial and/or temporal resolution. Because existing methodologies for quantifying tritium have some significant limitations, the development of tritium AMS has allowed improvements in reconstructing tritium exposure concentrations from environmental measurements and provides an important additional tool in assessing the temporal and spatial distribution of chronic exposure. Tritium exposure reconstructions using AMS were previously demonstrated for a tree growing on known levels of tritiated water and for trees exposed to atmospheric releases of tritiated water vapor. In these analyses, tritium levels were measured from milligram-sized samples with sample preparation times of a few days. Hundreds of samples were analyzed within a few months of sample collection and resulted in the reconstruction of spatial and temporal exposure from tritium releases. Although the current quantification limit of tritium AMS is not adequate to determine natural environmental variations in tritium concentrations, it is expected to be sufficient for studies assessing possible health effects from chronic environmental tritium exposure.

AN - 71899616; 15123790 AB - The human FANCG/XRCC9 gene, which is defective in Fanconi anemia complementation group G (FA-G) cells, was first cloned by genetic complementation of the mitomycin C (MMC) sensitivity of CHO mutant UV40. The CHO NM3 mutant was subsequently assigned to the same complementation group. The parental AA8 CHO cells are hemizygous at the FancG locus, and we identified frameshift mutations that result in N-terminal truncations of the protein in both UV40 and NM3. Hypersensitivity to DNA cross-linking agents, such as MMC, typically characterizes FA cells. By introducing the native CHO FancG gene into mutant NM3, we demonstrate that hamster FancG fully corrects the 3-fold sensitivity to methyl methanesulfonate (MMS) as well as the 10-fold sensitivity to MMC, whereas resistance to ionizing radiation did not increase appreciably. In contrast, hamster cDNA transformants showed incomplete correction for both MMC and MMS sensitivity. The constitutively expressed FancG protein is present in the cytoplasmic, nuclear and chromatin fractions. FancG protein levels and subcellular localization do not change appreciably as a function of cell cycle position. Our results are consistent with roles of FancG in both the nuclear and cytoplasmic compartments to maintain genomic stability in response to various genotoxic agents.

Melilite in some CAIs is replaced by spinel and Al-diopside and/or by anorthite, whereas spinel-pyroxene assemblages in CAIs and AOAs appear to be replaced by anorthite. Forsterite grains in several AOAs are replaced by low-Ca pyroxene. None of the CAIs or AOAs show evidence for Fe-alkali metasomatic or aqueous alteration. The mineralogy, textures, and bulk chemistry of most Acfer 094 refractory inclusions are consistent with their origin by gas-solid condensation and may reflect continuous interaction with SiO and Mg of the cooling nebula gas. It appears that only a few CAIs experienced subsequent melting. The Al-rich chondrules (ARCs; >10 wt% bulk Al (sub 2) O (sub 3) ) consist of forsteritic olivine and low-Ca pyroxene phenocrysts, pigeonite, augite, anorthitic plagioclase, + or -spinel, FeNi-metal, and crystalline mesostasis composed of plagioclase, augite and a silica phase. Most ARCs are spherical and mineralogically uniform, but some are irregular in shape and heterogeneous in mineralogy, with distinct ferromagnesian and aluminous domains. The ferromagnesian domains tend to form chondrule mantles, and are dominated by low-Ca pyroxene and forsteritic olivine, anorthitic mesostasis, and Fe,Ni-metal nodules. The aluminous domains are dominated by anorthite, high-Ca pyroxene and spinel, occasionally with inclusions of perovskite; have no or little FeNi-metal; and tend to form cores of the heterogeneous chondrules. The cores are enriched in bulk Ca and Al, and apparently formed from melting of CAI-like precursor material that did not mix completely with adjacent ferromagnesian melt. The inferred presence of CAI-like material among precursors for Al-rich chondrules is in apparent conflict with lack of evidence for melting of CAIs that occur outside chondrules, suggesting that these CAIs were largely absent from chondrule-forming region(s) at the time of chondrule formation. This may imply that there are several populations of CAIs in Acfer 094 and that mixing of "normal" CAIs that occur outside chondrules and chondrules that accreted into the Acfer 094 parent asteroid took place after chondrule formation. Alternatively, there may have been an overlap in the CAI- and chondrule-forming regions, where the least refractory CAIs were mixed with Fe-Mg chondrule precursors. This hypothesis is difficult to reconcile with the lack of evidence of melting of AOAs which represent aggregates of the least refractory CAIs and forsterite grains.

One of the most abundant of these amines, 2-amino-1-methyl-6-phenylimidazo[4, 5-b]pyridine (PhIP), induces breast, colon and prostate tumors in rats. Human dietary epidemiology studies suggest a strong correlation between either meat consumption or well- done muscle meat consumption and cancers of the colon, breast, stomach, lung and esophagus. For over 20 years our laboratory has helped define the human exposure to these dietary carcinogens. In this report we describe how various environmental exposures may modulate the risk from exposure to heterocyclic amines, especially PhIP. To assess the impact of foods on PhIP metabolism in humans, we developed an LC/MS/MS method to analyze the four major PhIP urinary metabolites following the consumption of a single portion of grilled chicken. Adding broccoli to the volunteers' diet altered the kinetics of PhIP metabolism. At the cellular level we have found that PhIP itself stimulates a significant estrogenic response in MCF-7 cells, but even more interestingly, co-incubation of the cells with herbal teas appear to enhance the response. Numerous environmental chemicals found in food or the atmosphere can impact the exposure, metabolism, and cell proliferation response of heterocyclic amines.

Techniques that can help better characterize particulate matter are required to better understand the constituents, causes, and sources of PM sub(2.5) aerosols. Measurement of the super(14)C/C ratio of the PM sub(2.5) aerosols, the absence of super(14)C in fossil carbon materials, and the known super(14)C/C levels in contemporary carbon materials allow the use of a two-component model to derive contemporary and fossil carbon contents of the particulate matter. Such data can be used to estimate the relative contributions of fossil fuels and biogenic aerosols to the total aerosol loading. Here, the methodology for performing such an assessment using total suspended particulate hi-vol aerosol samplers to collect PM sub(2.5) aerosols on quartz fiber filters and the technique of accelerator mass spectrometry to measure super(14)C/C ratios is presented and illustrated using PM sub(2.5) aerosols collected at Yosemite National Park.

AN - 85377219; pmid-15101641 AB - Time-reversal (T/R) communications is a new application area motivated by the recent advances in T/R theory. Although perceived by many in signal processing as simply an application of matched-filter theory, a T/R receiver offers an interesting solution to the communications problem for a reverberant channel. In this paper, the performance of various realizations of the T/R receiver for an acoustic communications experiment in air is described along with its associated processing. The experiment is developed to evaluate the performance of point-to-point T/R receivers designed to extract a transmitted information sequence propagating in a highly reverberant environment. It is demonstrated that T/R receivers are capable of extracting the transmitted coded sequence from noisy microphone sensor measurements with zero-symbol error. The processing required to validate these experimental results is discussed. These results are also compared with those produced by an equivalent linear equalizer or inverse filter, which provides the optimal solution when it incorporates all of the reverberations.

Four ice avalanches were identified on the north slope of the Burhan Budai Shan several kilometers east of the Kunlun Pass, and two were identified on the south slope of the eastern Yuxi Feng, which is approximately 50 km west of the Kunlun Pass. These ice avalanches originated from steep-sided ice caps and progressed over and past the termini of outlet valley glaciers. In the Burhan Budai Shan, the ice avalanches comprised ice and snow that reached 2-3 km down valley beyond the snouts of the contemporary glaciers. Detailed study of the largest ice avalanche (B2) shows that the initial movement over the contemporary glacier was turbulent in nature, having a velocity >35 ms (super -1) . Beyond the contemporary glacier, the ice avalanche was confined within steep valley walls and entrenched paraglacial fans. Before coming to rest, this ice avalanche moved as a Bingham plastic flow at a velocity of < or =21 ms (super -1) . These ice avalanches transported little rock debris, and it is thus unlikely that they are important in contributing to the landscape evolution of this region. Yet, given the appropriate geologic and climatic conditions, ice avalanching may be an important process in the landscape evolution of high mountainous terrains. The frequency of such events is unknown, but such phenomena may become more common in the future as a consequence of increased glacier and slope instability caused by human- induced climate change. Ice avalanches, therefore, likely constitute a significant geologic hazard in the near future.

Geochemical tracer techniques including stable isotopes of water, tritium/helium-3 (T/ (super 3) He) dating, and deliberate gas tracer experiments are ideally suited for these investigations. These tracers were used to evaluate flow near an artificial recharge site in northern Orange County, California, where approximately 2.5X10 (super 8) m (super 3) (200,000 acre-feet) of water are recharged annually. T/ (super 3) He ages show that most of the relatively shallow ground water within 3 km of the recharge facilities have apparent ages 20 years at approximately 6 km. Gas tracer experiments using sulfur hexafluoride and xenon isotopes were conducted from the Santa Ana River and two spreading basins. These tracers were followed in the ground water for more than two years, allowing subsurface flow patterns and flow times to be quantified. Results demonstrate that mean horizontal ground water velocities range from 4 km/year. The leading edges of the tracer patch moved at velocities about twice as fast as the center of mass. Leading edge velocities are important when considering the potential transport of microbes and other "time sensitive" contaminants and cannot be determined easily with other methods. T/ (super 3) He apparent ages and tracer travel times agreed within the analytical uncertainly at 16 of 19 narrow screened monitoring wells. By combining these techniques, ground water flow was imaged with time scales on the order of weeks to decades.

Identification of a particular mineral or amorphous solid in a heterogeneous mixture by XAS depends on the spectral uniqueness of the element in the bonding environment associated with a component, and on absorption effects from the components and the matrix. A suite of 27 common, Fe-bearing reference compounds, including sulfides, carbonates, phosphates, oxides, oxyhydroxides, and phyllosilicates, was analyzed to empirically assess the utility of X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) for identifying a particular Fe mineral (or class of minerals) in a soil or sediment mixture. We show that XANES spectral features are useful for distinguishing qualitatively among major mineral classes, but not necessarily for identifying minerals within classes. A practical detection limit (based on empirical mixtures) for most mineral classes is on the order of 5% of the total atomic Fe absorption, but detection limits vary depending on the spectral uniqueness of the components, the number of components, and the matrix. Calibration curves for Fe sulfide and non-sulfide (phyllosilicate+ or -oxide) component mixtures were made independently from the analyses of XANES and EXAFS fluorescence spectra of binary and ternary mineral mixtures (at 5% total Fe) in a quartz matrix to mimic natural sediments. Because of differences in sample and matrix absorption and fluorescence among sulfide and phyllosilicate minerals, apparent component fractions of pyrite derived from fits deviated significantly from linear binary mixtures. We show that corrections for non-linear fluorescence (as much as 20%) are particularly important for binary mineral mixtures with different densities and absorption characteristics (such as sulfides and phyllosilicates), and for mixtures with similar component abundances (i.e., far from one end-member). An application of the fluorescence calibration for XANES and EXAFS is shown for natural samples. This study points out the importance of a high-quality, experimentally consistent reference compound library, and the need for calibration of fluorescence spectra, in order to quantify accurately the component fractions of complex mixtures using XAS.

We present a novel method of estimating epicentral distance by integrating observed travel times (Lg-Pn and Sn-Pn) measured on three-component (3C) single-station data with theoretical travel times for the same phase combinations determined from 3D velocity models. Theoretical travel times for the body-wave phases are estimated using raytracing through a 3D P- and S-wave velocity model, while the travel times for Lg are estimated either using raytracing techniques or with a constant velocity determined from synthetics. Backazimuths are determined by applying polarization techniques on 3C data. The backazimuth and distance are then used to determine the epicenter for the event. The results of applying this 3D single-station location methodology to well-located events in southern Asia show mislocation errors that are typically less than 6% of the total propagation path distance.

In order to provide a quantitative basis for interpreting and predicting the distribution of aqueous species between heulandite and aqueous solutions, ion exchange equilibrium between heulandite and aqueous solutions with respect to the binary cation pairs Ca (super 2+) -K (super +) , Ca (super 2+) -Na (super +) , K (super +) -Na (super +) , K (super +) -Sr (super 2+) , Na (super +) -Sr (super 2+) , and Ca (super 2+) -Sr (super 2+) was investigated. Homoionic Ca-, K-, and Na-heulandites prepared from natural heulandite were equilibrated with 0.1 N Cl (super -) solutions containing various proportions of the cations in a given binary pair at 55 and 85 degrees C to define isotherms describing partitioning of the cations over a wide range of heulandite and solution composition with respect to the cations in each pair. In general, the experiments equilibrated rapidly, within 11 to 15 weeks at 55 degrees C and 3 to 4 weeks at 85 degrees C. The exception was the Ca (super 2+) -Sr (super 2+) binary exchange, which did not equilibrate even after 3 months at 55 degrees C and 4 weeks at 85 degrees C. Slow exchange of Sr (super 2+) for Ca (super 2+) also prohibited preparation of homoionic Sr-heulandite from the natural (Ca-rich) heulandite within 10 weeks in 2N SrCl (sub 2) solution at 90 degrees C, although near homoionic Sr-heulandite was produced by exchange of K- and Na-heulandite. Experimentally determined isotherms were used to derive equilibrium constants for the ion exchange reactions and asymmetric Margules models describing the extent of non-ideality in extraframework solid solutions in heulandite. Regressed equilibrium constants for Ca (super 2+) -Na (super +) , Ca (super 2+) -K (super +) , and K (super +) -Na (super +) binary cation pairs at 55 degrees C are internally consistent among each other (complying with the triangle rule), indicating good accuracy of these data. The maximum departure from internal consistency among the equilibrium constants for three binary pairs was 900 J per mole of charge equivalents (eq) for the 55 degrees C experiments and 2300 J eq (super -1) for the 85 degrees C experiments. The applicability of the present experimental results and thermodynamic models was assessed by calculating the composition of heulandite in Icelandic geothermal systems from known compositions using the regressed thermodynamic properties of Ca (super 2+) -Na (super +) exchange at 85 degrees C. Calculations predict an average Ca mole fraction [defined as Ca/(Ca+Na)] in heulandite of 0.74, in excellent agreement with observed compositions of heulandite from geothermal and metamorphic systems in Iceland (0.75). Thermodynamic data for heulandite ion-exchange derived in this study can be used to predict partitioning of Ca, K, Na, and Sr between heulandite and aqueous solutions in geologic systems. Because heulandite is the most effective sink for Sr in basaltic aquifers that have undergone zeolite facies metamorphism, the experimental results of this study will provide essntial data for modeling Sr transport in aquifers in low-grade metabasalts.

The aim of the CEP was to provide University campuses with site-specific assessments of their earthquake strong motion exposure, to complement estimates they obtain from consultants according to the state-of-the-practice (SOP), i.e. Building Codes (UBC 97, IBC 2000), and Probabilistic Seismic Hazard Analysis (PSHA). The Building Codes are highly simplified tools, while the more sophisticated PSHA is still somewhat generic in its approach because it usually draws from many earthquakes not necessarily related to the faults threatening the site under study. Between 1996 and 2001, the site-specific studies focused on three campuses: Riverside, San Diego, and Santa Barbara. Each campus selected 1-3 sites to demonstrate the methods and procedures used by the CEP: Rivera Library and Parking Lots (PL) 13 and 16 at UCR, Thornton Hospital, the Cancer Center, and PL 601 at UCSD, and Engineering I building at UCSB. The project provided an estimate of strong ground motions at each selected site, for selected earthquake scenarios. These estimates were obtained by using an integrated geological, seismological, geophysical, and geotechnical approach, that brings together the capabilities of campus and laboratory personnel. Most of the site-specific results are also applicable to risk evaluation of other sites on the respective campuses. The CEP studies have provided a critical assessment of whether existing campus seismic design bases are appropriate. Generally speaking, the current assumptions are not acknowledging the severity of the majority of expected motions. Eventually, both the results from the SOP and from the CEP should be analyzed, to arrive at decisions concerning the design-basis for buildings on UC campuses.

Specimens were placed between two transducers, and the resonant frequencies of vibration were measured between 0.5 and 1.4 MHz. The elastic constants determined from the measured resonant frequencies in hydrated dentin exhibited slight hexagonal anisotropy, with the stiffest direction being perpendicular to the axis of the tubules (E sub(11)=25.1 GPa). This hexagonal anisotropy was small (E sub(33)/E sub(11)=0.92), and almost disappeared when the specimens were dried. In addition, there was a pronounced anisotropy in the Poisson's ratio of wet dentin: nu sub(21)=0.45; nu sub(31)=0.29. With drying in air, this anisotropy vanished: nu sub(21)= nu sub(31)=0.29. The isotropic Young's modulus of dried dentin was 28.1 GPa. RUS shows promise for determining the elastic constants in mineralized tissues.

AN - 71766503; 15036006 AB - We devised an assay to quantify the metabolites of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) in human urine following a single exposure to well-cooked meat. Our method uses LC/MS/MS to detect four metabolites and four deuterated internal standard peaks in a single chromatographic run. N2-OH-PhIP-N2-glucuronide was the most abundant urinary metabolite excreted by the 12 individuals who participated in our study. N2-PhIP glucuronide was the second most abundant metabolite for 8 of the 12 volunteers. The stability of PhIP metabolism over time was studied in three of the volunteers who repeated the assay eight times over a 2.5 year-period. PhIP metabolite excretion varied in each subject over time, although the rate of excretion was more constant. Our results suggest that quantifying PhIP metabolites should make future studies of individual susceptibility and dietary interventions possible. JF - Journal of chromatography.

AN - 80173168; 14585809 AB - The developmental consequences of chromosomal aberrations in embryos include spontaneous abortions, morphological defects, inborn abnormalities, and genetic/chromosomal diseases. Six germ-cell mutagens with different modes of action and spermatogenic stage sensitivities were used to investigate the relationship between the types of cytogenetic damage in zygotes with their subsequent risk of postimplantation death and of birth as a translocation carrier. Independent of the mutagen used, over 98% of paternally transmitted aberrations were chromosome type, rather than chromatid type, indicating that they were formed during the period between exposure of male germ cells and initiation of the first S phase after fertilization. There were consistent one-to-one agreements between the proportions of a) zygotes with unstable aberrations and the frequencies of dead embryos after implantation (slope = 0.87, confidence interval [CI]: 0.74, 1.16) and b) zygotes with reciprocal translocations and the frequency of translocation carriers at birth (slope = 0.74, CI: 0.48, 2.11). These findings suggest that chromosomal aberrations in zygotes are highly predictive of subsequent abnormal embryonic development and that development appears to proceed to implantation regardless of the presence of chromosomal abnormalities. Our findings support the hypothesis that, for paternally transmitted chromosomal aberrations, the fate of the embryo is already set by the end of G1 of the first cell cycle of development.

AN - 66644634; 15209414 AB - With the vast technological and informational resources increasingly available from investments in "genomics," toxicology and much of biological science, is faced with previously undreamed of opportunities and equally daunting challenges. The ability to generate the large quantities of data becoming routinely available could not be imagined a decade ago. The complexities of data analysis are increasingly the rate-limiting element in scientific advances. The expectations that these large scientific investments will reduce the incidence of human disease and improve health are very high. An emphasis on genetic variation and Toxicogenetics is expected to yield risk estimates for specific rather than average individuals and individuals with varied lifestyles and complex patterns of exposure. Examples from studies of polymorphic variation in DNA repair genes in the healthy population and cancer risk highlight the complexity and challenges of incorporating genetic variation into quantitative estimates of risk associated with environmentally relevant exposures. Similar issues exist in selecting the animal models most appropriate for predicting human risk from environmental exposures to toxic agents.

Rapid incision of approximately 0.2 mm/yr from 2.7 to ca. 1.5 Ma slowed markedly to approximately 0.03 mm/yr thereafter, likely reflecting the combined effects of a transient erosional response to Pliocene rock uplift and periodic mantling of riverbeds with glacially derived sediment in the late Quaternary. While approximately 400 m of incision has occurred in the past 2.7 m.y., outpacing interfluve erosion and thereby increasing the local relief, canyons as deep as 1.6 km existed prior to that time. These new erosion rates strengthen the case for tectonically driven late Cenozoic uplift.

Although the trapped noble gases in five DaG samples show ratios typical of solar or planetary gases, in all other DaG samples, they are dominated by atmospheric contamination, which increases with the degree of weathering. Cosmic ray exposure (CRE) ages of DaG chondrites range from approximately 1 Myr to 53 Myr. The CRE age distribution of 10 DaG L chondrites shows a cluster around 40 Myr due to four members of a large L6 chondrite shower. The CRE age distribution of 19 DaG H chondrites shows only three ages coinciding with the main H chondrite peak at approximately 7 Myr, while seven ages are <5 Myr. Two of these H chondrites with short CRE ages (DaG 904 and 908) show evidence of a complex exposure history. Five of the H chondrites show evidence of high shielding conditions, including low (super 22) Ne/ (super 21) Ne ratios and large contributions of neutron-capture (super 36) Cl and (super 41) Ca. These samples represent fragments of two or more large pre-atmospheric objects, which supports the hypothesis that the high H/L chondrite ratio at DaG is due to one or more large unrecognized showers. The (super 14) C concentrations correspond to terrestrial ages <35 kyr, similar to terrestrial ages of chondrites from other regions in the Sahara but younger than two DaG achondrites. Despite the loss of cosmogenic (super 36) Cl and (super 41) Ca during oxidation of metal and troilite, concentrations of (super 36) Cl and (super 41) Ca in the silicates are also consistent with (super 14) C ages <35 kyr. The only exception is DaG 343 (H4), which has a (super 41) Ca terrestrial age of 150+ or -40 kyr. This old age shows that not only iron meteorites and achondrites but also chondrites can survive the hot desert environment for more than 50 kyr. A possible explanation is that older meteorites were covered by soils during wetter periods and were recently exhumed by removal of these soils due to deflation during more arid periods, such as the current one, which started approximately 3000 years ago. Finally, based on the (super 26) Al/ (super 21) Ne and (super 10) Be/ (super 21) Ne systematics in 16 DaG meteorites, we derived more reliable estimates of the (super 10) Be/ (super 21) Ne production rate ratio, which seems more sensitive to shielding than was predicted by the semi-empirical model of Graf et al. (1990) but less sensitive than was predicted by the purely physical model of Leya et al. (2000).

The delta (super 13) C values of DOC in the Missouri River varied approximately 2.0 per mil over a one-year period and approximately followed mean water temperature. This suggested contribution of algae components into the DOC pool. Dissolved hydrophobic acids, which constituted approximately 50% of the DOC showed little variation and were consistent with terrestrial plant-derived material (-25 to -28 per mil). Daily mean stream flow measurements at St. Josephs and at Hermann were used to compute the fraction of water derived upstream of the State of Missouri versus that derived within State. The concentration and radiocarbon ( (super 14) C) content of DOC sampled in St. Louis exhibited strong linear correlation with fraction of discharge and were related to the marked regional climate differences between upstream (approx. 20 in rain/yr) and downstream (approx. 40 in rain/yr) of this large river system. The DOC concentration varied from 3.0 mg/L for upstream-dominated discharge to 7.0 mg/L for downstream-dominant. The dissolved hydrophobic acids in upstream discharge had (super 4) C contents as low as 87 pmc; whereas, in downstream discharge it was near 100 pmc. To better understand the (super 14) C variability, the (super 14) C content of several dissolved hydrophobic acids isolated from rivers and lakes representing various climates were measured. The (super 14) C data ranged from 77 to 130 pmc and showed a strong positive correlation with the mean annual precipitation rate (10 in/yr to 80 in/yr; proxy for net primary productivity) of the sample area. The range in calculated apparent (super 14) C ages is at least a factor of five higher than the range represented in precipitation rates, suggesting soil retention likely has a secondary role in controlling the (super 14) C variability of hydrophobic acids in water.

Organic carbon loading to the SWP is a growing concern for water utilities serving 23 million Californians owing to the potential for DOC to form harmful disinfection by-products. An accurate conceptual understanding of carbon dynamics within the Sacramento-San Joaquin Delta and SWP is critically needed to assess the impact of proposed CALFED ecosystem restoration activities (e.g., construction of in-Delta reservoirs and tidal wetlands). The 14C content of DOC was measured in riverine input to the Delta and in three agricultural drains during the spring runoff period (April 2003) and at the start of the irrigation season (June 2003). DOC fractions measured included bulk DOC and dissolved hydrophobic acids (HPOA). In the agricultural drains the 14C content of HPOA compounds and bulk DOC overlapped and ranged from 0.73 to 0.86 pmc. The 14C content of bulk DOC and HPOA fractions in riverine input to the Delta was higher, ranging from 0.96 to 1.07 pmc. The 14C content of SWP waters, ca. 1.00 pmc, was bracketed by the riverine and agricultural values and showed little variation between the two sampling dates. In contrast, mean 14C content of HPOA in the rivers increased from 0.96 to 1.08 pmc between April and June, while in the agricultural drains mean values declined slightly from 0.81 to 0.79 pmc. Using HPOA 14C content and a simple two-component mixing model we estimated that, during April 2003, 93% of the carbon in the SWP was derived from riverine inputs. During June 2003 DOC loading to the SWP was split about equally between riverine inputs and agricultural drainage.

Incision significantly accelerated beginning at the onset of the last glacial period (30 to 35 ky). A vertical transect of 4 samples, each on one prominent terrace (21 m elevation range) suggests that from >100 to approximately 32 ky, the Susquehanna incised through competent schist at 150 m below present and river discharge and sediment load were presumably elevated by glacial meltwater. Furthermore, 14 samples collected in a cross section at the upper end of the gorge yield an incision rate of 0.6 m/ky (R (super 2) = 0.94) commencing approximately 31 ky. Similarly, mean ages from numerous samples collected longitudinally along each of the terrace levels suggest incision rates between 0.6 and 0.7 m/ky beginning approximately 30 ky and ending approximately 14 ky. Alternatively, amalgamating the results of 24 samples collected in vertical transects down the fronts of 3 mid-channel islands suggest incision at 0.1 m/ky from approximately 46 to approximately 24 ky, increasing to 1.0 m/ky between approximately 21 and approximately 14 ky. The timing and rate of incision along both the glaciated Susquehanna and unglaciated Potomac Rivers (100 km south) are remarkably similar (0.8 m/ky from 37 to 13 ky) suggesting that large rivers draining the Atlantic Passive margin are responding to regional forcings likely including climate induced changes in flood frequency, sediment load, and isostasy.

For 12 basins south of the Wisconsin glacial margin, the sediment generation (erosion) rates range from 8-19 m/My, with a mean of 13 m/My. The 10-Be based rates are positively correlated (R (super 2) = 0.5) with sediment yields obtained from USGS gaging stations at the sample sites, implying broadly consistent rates of sediment yield on decadal time scales and erosion on millennial timescales. However, this correlation does not include three Piedmont basins with sediment yields that imply erosion rates in excess of 30 m/My. These three basins are heavily farmed, including widespread use of traditional agricultural practices. Results are forthcoming for an additional 72 sediment samples, dominantly from basins <10 sq. km in area. Most of these basins are south of the Wisconsin glacial margin, have mean slopes that span a range of 20 degrees , represent three lithologies (sandstone, shale, and schist), and are distributed among the Appalachian Plateaus, Piedmont, and Valley and Ridge physiographic provinces. The results from these basins will be used to investigate relationships between sediment generation rates and GIS-measurable characteristics of the present-day landscape.

The magnitude of the oceanic reservoir age in the inland waters of the Georgia Basin and Puget Lowland of northwestern North America is inferred from radiocarbon ages on shell-wood pairs in Saanich Inlet and previously published estimates. The weighted mean oceanic reservoir correction in the early and mid Holocene is -720+ or -90 yr, slightly smaller than, but not significantly different from, the modern value. The correction in late-glacial time is -950+ or -50 yr. Valley-head sites yield higher reservoir values (-1200+ or -130 yr) immediately after deglaciation. The magnitude of the gyttja reservoir effect is inferred from pairs of bulk gyttja and plant macrofossil ages from four lakes in the region. Incorporation of old carbon into basal gyttja yields ages from bulk samples that are initially about 600 yr too old. The reservoir age declines to less than 100 yr after the first millennium of lake development. When these corrections are accounted for, dates of deglaciation and late-glacial sea-level change in the study area are pushed forward in time by more than 500 yr.

The simulations with prescribed SSTs and sea ice are available from the Atmospheric Model Intercomparison Project (AMIP), and coupled ocean-atmosphere simulations are available from the Coupled Model Intercomparison Project (CMIP). We compare CMIP runs from two coupled models sharing a common atmosphere component (but different ocean components) with the atmosphere component's AMIP run. All three simulations have similar errors that presumably originate in the atmosphere component. Replacing the observed SSTs and sea ice amounts in the AMIP simulation with the interactive submodels used in the CMIP simulations tends to degrade the level of agreement with climate observations. Increases in root-mean-square (RMS) errors, however, are mostly less than 30% and often less than 10% of the magnitude of natural climate variations. Exceptions to this rule occur mainly in the tropics, most notably for geopotential height at 500 hPa and for temperature near the tropopause. These variables show increases in RMS errors that are comparable to observational standard deviations. The coupled model simulations are taken from the end of 300 year control runs without flux "corrections" at the ocean-atmosphere interface. Their similarity to results from the prescribed SST atmosphere model implies that modern coupled models can maintain stable multicentury simulations without flux adjustments.

Different mixtures and configurations of quartz sand and 10% Na-montmorillonite clay were investigated using solutions of NaCl, CaCl (sub 2) , and deionized water. A sample containing 10% dispersed clay was also studied using fluids containing 20- and 500-ppm trichloroethylene (TCE). Each sample's electrical properties after fluid saturation were measured at frequencies between 10 (super -2) and 10 (super 6) Hz by using the four-electrode method with Ag-AgCl inner electrodes at room temperature and 412 kPa confining pressure, which corresponds to a soil depth of 15-20 m. Our results show that adding TCE had a small effect on electrical resistivity: resistivity was greater at higher concentrations of TCE. The influence of TCE on electrical properties was most prominent in plots of loss tangent as a function of frequency. These plots showed that loss-tangent peaks occurred at approximately 200 Hz and that peak and peak frequency were smaller at higher concentrations of TCE. Additional experiments were performed on a sample that contained a distinct clay layer parallel to the current flow. The electrical properties of the sample were measured as it was saturated with deionized water and CaCl (sub 2) solutions, and as an ethanol-water mixture (80:20) was flowed through the sample. Resistivity increased by about a factor of 4 as the ethanol mixture replaced the water solution. Nondestructive x-ray imaging of the sample at various stages of dewatering indicated a decrease in the thickness of the clay layer as more pore volumes of ethanol-water were flowed. Our results show that electrical measurements are useful tools for characterizing porous rocks and soils and that it is feasible to remotely detect the presence and follow the transport of contaminants such as TCE in the subsurface.

However, most of these records are compromised by chronological flaws, making problematic any comparisons with climatic interpretations based on other records (e.g., GISP2 in Greenland). We report here a high-resolution pollen record with a secure chronology constrained by 26 (super 14) C dates on terrestrial macrofossils from Steel Lake, central Minnesota. About 11.2 ka cal BP (11,000 calibrated yr before present) the late-glacial Picea forest near Steel Lake was succeeded abruptly by Pinus banksiana and/or resinosa. The Pinus forest began to open 9.4 ka cal BP with the expansion of prairie taxa, and a pine parkland or savanna prevailed until about 8 ka cal BP, when Quercus replaced Pinus to become the dominant tree in the prairie areas for 4500 yr. The close chronological control permits the correlation of key vegetational changes with those at other reliably dated sites in the eastern Dakotas and in Minnesota, suggesting that the abrupt decline of the spruce forest was time-transgressive from southwest to northeast during 2000 yr, and that the development of prairie was time-transgressive in the same direction over 2600 yr. Correlation of key pollen horizons at Steel Lake with those in the high-resolution pollen profiles of Elk Lake, ca. 50 km northwest of Steel Lake, suggests that the well-known Elk Lake varve chronology for the early Holocene is about 1000 yr too young.

The life histories of each individual animal are modeled separately. The individuals can have the status of residents or wanderers and belong to behaviorally differing groups of juveniles or adults and males or females. Their territory defending and monogamous behavior is taken into consideration. The resource, green vegetation, grows depending on seasonal climatic characteristics and is diminished due to the herbivore's grazing. Other specifics such as a varying personal energetic level due to feeding and starvation of the individuals, mating preferences, avoidance of competitors, dispersal of juveniles, as a result of site overgrazing, etc., are included in the model. We determined model parameters from real data for the species Microtus ochrogaster (prairie vole). The simulations are done for a case of an enclosed habitat without predators or other species competitors. The goal of the study is to find the relation between size of habitat and population persistence. The experiments with the model show the populations go extinct due to severe overgrazing, but that the length of population persistence depends on the area of the habitat as well as on the presence of fragmentation. Additionally, the total population size of the vole population obtained during the simulations exhibits yearly fluctuations as well as multi-yearly peaks of fluctuations. This dynamics is similar to the one observed in prairie vole field studies.

Thus, rather than evaluating the ecological impact on species in the immediate vicinity of the release, it may be more ecologically meaningful to determine if population impacts occur at the landscape level. In order to do this, the cumulative impact of all releases in the landscape under consideration must be evaluated. If the release sites are viewed as localized areas that are no longer available for use by ecological receptors (i.e., no longer part of the habitat), this can be thought of as a form of habitat fragmentation. Habitat fragmentation is typically viewed as the loss of large areas of habitat within a landscape, leaving small isolated patches of intact habitat within a hostile matrix. Small-scale contaminant releases, on the other hand, result in small uninhabitable areas within a primarily intact habitat. With this consideration in mind, we analyzed the wildlife and conservation biology literature to determine if information on habitat size requirements such as home-range or critical patch size could inform us about the potential for impact at the landscape level from release sites based on the size of the release alone. We determined that evaluating the impact of release size had to be conducted within a contextual basis (considering the existing state of the landscape). Therefore, we also reviewed the population modeling literature to determine if models could be developed to further evaluate the impact of the spatial extent of chemical releases on the landscape. We identified individual-based models linked to geographic information systems to have the greatest potential in investigating the role of release size with respect to population impacts at the landscape level.

Annual mean Delta 14C has a dynamic range of nearly 175ppt, with a total range of nearly 200ppt. Prebomb values average -56ppt and the annual mean postbomb maxima occurs in 1985 with a value of +117%. Interannual variability in the record reflects surface current variations in conjunction with surface wind changes associated with ENSO. During El Nino years the waters of the Solomon Sea reflect a stronger influence of waters advected in from the east by the SEC and less 'pure' subtropical water. This is most likely accomplished by a southward shift of the equatorward branch of the SEC during El Nino. There is an overall decrease in the relative proportion of eastern tropical water that is interpreted as a decrease in the strength and intensity of the shallow circulation of the tropical Pacific during the latter portion of the twentieth century. If validated, this secular trend bears strongly upon the rate of extratropical-tropical recirculation and the redistribution of heat and salt within the tropical Pacific.

Interest in the phenomena waxed in the 1980s, but models developed at that time remain limited by the lack of both detailed, time-resolved wet deposition pattern measurements for model confirmation and real-time rain data for model execution. Recently, new rain products have become available that can revolutionize real-time use of precipitation scavenging models on the regional scale. We have utilized a 4-km, hourly resolution precipitation data set from the Arkansas Red-Basin River Forecast Center. A standard below-cloud aerosol scavenging model has been modified to incorporate the potentially larger scavenging in heavy rain events. This paper demonstrates the model on a sample rainfall data set. The simulations demonstrate the concentrating effect of rainfall, especially heavy rain, on deposition patterns. Wet deposition played an important role in the simulated fate and transport, removing as much as 70% of the released aerosol.

Recent developments in response to threats posed by chemical and biological warfare agents. AN - 71552605; 14660116 AB - Recent terrorist events underscore the urgent need to develop a comprehensive set of health-protective cleanup standards and effective decontamination technologies for use in the restoration of civilian facilities. Accurate scientific information remains limited in the area of biological warfare agents. However, new guidelines and calculated cleanup values are emerging for initial re-entry and long-term reoccupation following use of chemical warfare agents. This article addresses airborne, soil, and surface exposures following release of G-type chemical warfare agents and VX. Cleanup goals should be tailored to the type of population that may be exposed, potential exposure times, and other scenario-specific considerations. Three different airborne concentrations are proposed for cleanup of public sector facilities. One value is recommended for initial re-entry; a more conservative value is recommended for long-term monitoring and increased public confidence; and a third, even more conservative concentration represents essentially a no-effect level for round-the-clock airborne exposure. Health-based cleanup levels are provided for contaminated residential and industrial soil. Results are presented on the outcome of a preliminary risk assessment to determine safe surface levels (e.g., walls, floors, and handrails) for cleanup after exposure to the G agents and VX. Because specific cleanup criteria for most biological warfare agents remain problematic, recommendations are made for filling the knowledge gaps.

We report here the presence of a (super 13) C depletion associated with a (super 15) N enrichment in an anhydrous interplanetary dust particle. Our observations suggest that the anomalies are carried by heteroatomic organic compounds. Theoretical models indicate that low-temperature formation of organic compounds in cold interstellar molecular clouds can produce carbon and nitrogen fractionations, but it remains to be seen whether the specific effects observed here can be reproduced.

AN - 51827042; 2004-054167 AB - Understanding the nature and composition of larger extraterrestrial bodies that may collide with the Earth is important. One source of information lies in the record of ancient impact craters, some of which have yielded chemical information as to the impacting body. Many deeply eroded craters have no remaining melt sheet or ejecta yet may contain impactor residue within basement fractures. The emplacement mechanism for fractionated siderophile residues is likely to be gaseous, although, melt droplets and some solid materials may survive. For breccia- and melt-filled fractures to contain extraterrestrial material, they must form very early in the impact process. Most current numerical models do not dwell on the formation and location of early major fractures, although, fractures in and around small craters on brittle glass exposed to hypervelocity impact in low Earth orbit have been successfully simulated. Modelling of fracture development associated with larger craters may help locate impact residues and test the models themselves.

Our study sites are distributed along a 2 km ridgeline transect that spans 2090 to 2750 m in altitude, and encompasses marked contrasts in both vegetative cover and snow depth, but is underlain by a single, roughly uniform, granodiorite bedrock. Cosmogenic nuclides in colluvial soils reveal that denudation rates vary by less than a factor of 1.4 (104-144 t/km (super 2) /yr) along this transect. Bulk elemental analyses indicate that, relative to the parent rock, soils are less intensively weathered with increasing altitude, and show little evidence of weathering-related mass losses near the top of the ridge. Chemical weathering rates decrease rapidly with increasing altitude, both in absolute terms (from 24 to 0 t/km (super 2) /yr) and as a fraction of total denudation rates (from 20 to 0%). Thus these results indicate an increasing dominance of physical erosion with altitude. The observed decrease in chemical weathering rates is greater than one would predict from the decrease in mean annual temperature using simple weathering kinetics, suggesting that weathering rates along our transect may also be affected by the progressive decline in vegetative cover and increase in snow depth with increasing altitude. These results, considered together with weathering rate measurements for a wide range of climates in the Sierra Nevada, USA, suggest that chemical weathering rates may be particularly sensitive to differences in climate at higher-altitude sites. Consistent with this hypothesis, chemical weathering rates fall virtually to zero at the highest sites on our transect, suggesting that sparsely vegetated, high-altitude crystalline terrain may often be characterized by extremely slow silicate weathering rates.

Constant Kd models for describing radionuclide retardation are not valid under these conditions because of strong competition for sorption sites by abundant Na+ ions, and because of dramatically changing solution compositions with time as the highly concentrated tank fluid becomes diluted as it mixes with infiltrating rainwater. A mechanistic multicomponent sorption model is required that can account for effects of competition and spatially and temporally variable solution compositions. To investigate the influence of the high ionic strength tank fluids on Cs (super +) migration, numerical calculations are performed using the multiphase-multicomponent reactive transport code FLOTRAN. The computer model describes reactive transport in nonisothermal, variably saturated porous media including both liquid and gas phases. Pitzer activity coefficient corrections are used to describe the high ionic strength solutions. The calculations take into account multicomponent cation exchange based on measured selectivity coefficients specific to the Hanford sediments. Solution composition data obtained from Well 299-W23-19, documenting a moderately concentrated leak from the SX-115 tank, are used to calibrate the model. In addition to exchange of cations Na (super +) , K (super +) , Ca (super 2+) , and Cs (super +) , aqueous complexing and a kinetic description of precipitation and dissolution of calcite are also included in the calculations. The fitted infiltration rate of 0.08 m yr-1, and fitted cation exchange capacity of 0.05 mol kg-1 are consistent with measured values for the Hanford sediments. A sensitivity analysis is performed for Na (super +) concentrations ranging from 5 to 20 m to investigate the mobility of Cs (super +) interacting with a highly concentrated background electrolyte solution believed to have been released from the SX-108/SX-109 tanks. The calculations indicate that during the initial period of the tank leak when Cs (super +) is associated with high Na (super +) concentrations, there is little retardation of the Cs (super +) plume. However, as time increases the Na (super +) and Cs (super +) profiles become chromatographically separated due to differences in their selectivity coefficients and dilution of the tank leak plume with infiltrating rainwater. Eventually the two species become separated spatially, and Cs (super +) becomes highly retarded and remains essentially fixed in the sediments by cation exchange. For the 20 m Na (super +) simulated tank leak, the sorbed Cs (super +) profile is in close agreement with data obtained from the slant borehole and consistent with the estimated tank supernatant concentration. The simulations suggest that natural attenuation processes should result in strong fixation of Cs (super +) in the vadose zone in spite of the release of high Na (super +) concentrations during a tank leak event.

Optical trapping immobilizes the particle while maintaining it in the center of the laser beam path and within the laser focus, thus maximizing the collection of its Raman signals. The single particle is completely isolated from other particles and substrate surfaces, therefore eliminating any unwanted background signals and ensuring that information is collected only from the selected, individual particle. In this work, an inverted confocal Raman microscope is combined with optical trapping to probe and analyze bacterial spores in solution. Rapid, reagentless detection and identification of bacterial spores with no false positives from a complex mixed sample containing polystyrene and silica beads in aqueous suspension is demonstrated. In addition, the technique is used to analyze the relative concentration of each type of particle in the mixture. Our results show the feasibility for incorporating this technique in combination with a flow cytometric-type scheme in which the intrinsic Raman signatures of the particles are used instead of or in addition to fluorescent labels to identify cells, bacteria, and particles in a wide range of applications.

This article describes a mass spectrometry-based analytical technique for the real-time and reagentless characterization of individual airborne cells without sample preparation. We characterize the mass spectral signature of individual Bacillus spores and demonstrate the ability to distinguish two Bacillus spore species, B. thuringiensis and B. atrophaeus, from one another very accurately and from the other biological and nonbiological background materials tested with no false positives at a sensitivity of 92%. This example demonstrates that the chemical differences between these two Bacillus spore species are consistently and easily detected within single cells in seconds.

Polar DOM was the most abundant DOM fraction, accounting for 56% of the isolated DOM. Colloidal organic matter was (super 14) C-age dated to be about 100% modern carbon and all of the DOM fractions were (super 14) C-age dated to be between 94 and 95% modern carbon. Average structural models of each DOM fraction were derived that incorporated quantitative elemental and infrared, (super 13) C-NMR, and electrospray/mass spectrometric data. The polar DOM model consisted of open-chain N-acetyl hydroxy carboxylic acids likely derived from N-acetyl heteropolysaccharides that constituted the colloidal organic matter. The less polar DOM fraction models consisted of aliphatic alicyclic ring structures substituted with carboxyl, hydroxyl, ether, ester, and methyl groups. These ring structures had characteristics similar to terpenoid precursors. All DOM fractions in the Great Salt Lake are derived from algae and bacteria that dominate DOM inputs in this lake.

Other natural boundary conditions included variable flow velocity and undersaturation of seawater with respect to the hydrate-forming species. Four cylindrical test specimens of pure, polycrystalline CH (sub 4) and CO (sub 2) hydrate were grown and fully compacted in the laboratory, then transferred by pressure vessel to the seafloor (1028 m depth), exposed to the deep ocean environment, and monitored for 27 hours using time-lapse and HDTV cameras. Video analysis showed diameter reductions at rates between 0.94 and 1.20 mu m/s and between 9.0 and 10.6.10 (super -2) mu m/s for the CO (sub 2) and CH (sub 4) hydrates, respectively, corresponding to dissolution rates of 4.15+ or -0.5 mmol CO (sub 2) /m (super 2) s and 0.37+ or -0.03 mmol CH (sub 4) /m (super 2) s. The ratio of the dissolution rates fits a diffusive boundary layer model that incorporates relative gas solubilities appropriate to the field site, which implies that the kinetics of the dissolution of both hydrates is diffusion-controlled. The observed dissolution of several mm (CH (sub 4) ) or tens of mm (CO (sub 2) ) of hydrate from the sample surfaces per day has major implications for estimating the longevity of natural gas hydrate outcrops as well as for the possible roles of CO (sub 2) hydrates in marine carbon sequestration strategies.

AN - 51716115; 2005-042784 AB - Some of the most valuable paleoclimate archives yet recovered are the multi-proxy records from the Greenland GISP2 and GRIP ice cores. The crucial importance of these data arises in part from the strong correlations that exist between the Greenland delta (super 18) O records and isotopic or other proxies in numerous other Northern Hemisphere paleoclimate sequences. These correlations could, in principle, allow layer-counted ice-core chronologies to be transferred to radiocarbondated paleoclimate archives, thus providing a (super 14) C calibration for the Last Glacial Maximum and Isotope Stage 3, back to the instrumental limits of the (super 14) C technique. However, this possibility is confounded by the existence of numerous different chronologies, as opposed to a single (or even a "best") ice-core time scale. This paper reviews how the various chronologies were developed, summarizes the differences between them, and examines ways in which further research may allow a (super 14) C calibration to be established.

Thus, it is desirable, when possible, to use calibration data obtained from secure dendrochronologically-dated wood from the corresponding hemisphere. In this paper, we outline the recent work and point the reader to the internationally recommended data set that should be used for future calibration of Southern Hemisphere (super 14) C dates.

The new data map (super 14) C variations ranging from the current limit of the tree-ring calibration (11,900 calendar years before present [cal BP], Kromer and Spurk 1998, now updated to 12,400 cal BP, see Kromer et al., this issue), to the (super 14) C-dating limit of 50,000 cal BP, with detailed structure between 14 to 16 cal kyr BP and 19 to 24 cal kyr BP. Samples older than 25,000 cal BP were analyzed with high-precision (super 231) Pa dating methods (Pickett et al. 1994; Edwards et al. 1997) as a rigorous second check on the accuracy of the (super 230) Th ages. These are the first coral calibration data to receive this additional check, adding confidence to the age data forming the older portion of the calibration. Our results, in general, show that the offset between calibrated and (super 14) C ages generally increases with age until about 28,000 cal BP, when the recorded (super 14) C age is nearly 6800 yr too young. The gap between ages before this time is less; at 50,000 cal BP, the recorded (super 14) C age is 4600 yr too young. Two major (super 14) C-age plateaus result from a 13 ppm drop in Delta (super 14) C between 14-15 cal kyr BP and a 700 ppm drop in Delta (super 14) C between 22-25 cal kyr BP. In addition, a large atmospheric Delta (super 14) C excursion to values over 1000 ppm occurs at 28 cal kyr BP. Between 20 and 10 cal kyr BP, a component of atmospheric Delta (super 14) C anti-correlates with Greenland ice Delta (super 18) O, indicating that some portion of the variability in atmospheric Delta (super 14) C is related to climate change, most likely through climate-related changes in the carbon cycle. Furthermore, the 28-kyr excursion occurs at about the time of significant climate shifts. Taken as a whole, our data indicate that in addition to a terrestrial magnetic field, factors related to climate change have affected the history of atmospheric (super 14) C.

Samples were collected at 3 European mountain sites at height levels of 1205 m (Schauinsland), 1800 m (Vermunt), and 3450 m asl (Jungfraujoch), and analyzed in the Heidelberg Radiocarbon Laboratory. The data set from Jungfraujoch (1986-2003) is considered to represent the free tropospheric background level at mid-latitudes of the Northern Hemisphere, as it compares well with recent (yet unpublished) measurements made at the marine baseline station Mace Head (west coast of Ireland). The Vermunt and Schauinsland records are significantly influenced by regional European fossil fuel CO (sub 2) emissions.

Here, we present the revised Holocene oak chronology (HOC) and the Preboreal pine chronology (PPC) with respect to revisions, critical links, and extensions. Since 1998, the HOC has been strengthened by new trees starting at 10,429 BP (8480 BC). Oaks affected by cockchafer have been identified and discarded from the chronology. The formerly floating PPC has been cross-matched dendrochronologically to the absolutely dated oak chronology, which revealed a difference of only 8 yr to the published (super 14) C wiggle-match position used for IntCal98. The 2 parts of the PPC, which were linked tentatively at 11,250 BP, have been revised and strengthened by new trees, which enabled us to link both parts of the PPC dendrochronologically. Including the 8-yr shift of the oak-pine link, the older part of the PPC (pre-11,250 BP) needs to be shifted 70 yr to older ages with respect to the published data (Spurk 1998). The southern German part of the PPC now covers 2103 yr from 11,993-9891 BP (10,044-7942 BC). In addition, the PPC was extended significantly by new pine chronologies from other regions. A pine chronology from Avenches and Zurich, Switzerland, and another from the Younger Dryas forest of Cottbus, eastern Germany, could be crossdated and dendrochronologically matched to the PPC. The absolutely dated tree-ring chronology now extends back to 12,410 cal BP (10,461 BC). Therefore, the tree-ring based (super 14) C calibration now reaches back into the Central Younger Dryas. With respect to the Younger Dryas-Preboreal transition identified in the ring width of our pines at 11,590 BP, the absolute tree-ring chronology now covers the entire Holocene and 820 yr of the Younger Dryas.

These (super 14) C data for the summer season of each hemisphere were employed to construct zonal, hemispheric, and global data sets for use in regional and global carbon model calculations including calibrating and comparing carbon cycle models. In addition, extended monthly atmospheric (super 14) C data sets for 4 different zones were compiled for age calibration purposes. This is the first time these data sets were constructed to facilitate the dating of recent organic material using the bomb (super 14) C curves. The distribution of bomb (super 14) C reflects the major zones of atmospheric circulation. JF - Radiocarbon AU - Hua, Quan AU - Barbetti, Mike A2 - Reimer, Paula J.

While several high-resolution records exist beyond this limit, these data sets exhibit discrepancies of up to several millennia. As a result, no calibration curve for the time range 26-50 cal kyr BP can be recommended as yet, but in this paper the IntCal04 working group compares the available data sets and offers a discussion of the information that they hold.

The method takes account of uncertainty on both the (super 14) C and calendar scales, coherently integrating data, the calendar age estimates of which arise from different dating methods. It also allows for correlation between observations, if they have particular sources of uncertainty in common. We adopt an approach based on a random walk model, tailoring it to take account of possible calendar age offsets between different data sources by adding a random effect component. The latter allows us to use the same modeling framework for constructing the new calibration curve IntCal04, the comparison curve NotCal04, the Southern Hemisphere curve SHCal04, and the marine calibration curve Marine04.

Based on the strong rise of Delta (super 14) C at the onset of the Younger Dryas (YD) and wiggle-matching of the decadal-scale Delta (super 14) C fluctuations, we can anchor the floating chronology to the Cariaco varve chronology. We observe a marine reservoir correction higher than hitherto assumed for the Cariaco site, of up to 650 yr instead of 400 yr, for the full length of the comparison interval. The tree-ring Delta (super 14) C shows several strong fluctuations of short duration (a few decades) at 13,800, 13,600, and 13,350 cal BP. The amplitude of the strong Delta (super 14) C rise at the onset of the YD is about 40 ppm, whereas in the marine data set the signal appears stronger due to a re-adjustment of the marine mixed-layer Delta (super 14) C towards the atmospheric level.

The new calibration data set for terrestrial samples extends from 0-26 cal kyr BP, but with much higher resolution beyond 11.4 cal kyr BP than IntCal98. Dendrochronologically-dated tree-ring samples cover the period from 0-12.4 cal kyr BP. Beyond the end of the tree rings, data from marine records (corals and foraminifera) are converted to the atmospheric equivalent with a site-specific marine reservoir correction to provide terrestrial calibration from 12.4-26.0 cal kyr BP. A substantial enhancement relative to IntCal98 is the introduction of a coherent statistical approach based on a random walk model, which takes into account the uncertainty in both the calendar age and the (super 14) C age to calculate the underlying calibration curve (Buck and Blackwell, this issue). The tree-ring data sets, sources of uncertainty, and regional offsets are discussed here. The marine data sets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed in brief, but details are presented in Hughen et al. (this issue a). We do not make a recommendation for calibration beyond 26 cal kyr BP at this time; however, potential calibration data sets are compared in another paper (van der Plicht et al., this issue).

Several ways of reporting (super 14) C activity levels relative to a standard were also established, but no specific instructions were given for reporting nuclear weapons-testing (post-bomb) (super 14) C levels in samples. Because the use of post-bomb (super 14) C is becoming more prevalent in forensics, biology, and geosciences, a convention needs to be adopted. We advocate the use of fraction modern with a new symbol F (super 14) C to prevent confusion with the previously used Fm, which may or may not have been fractionation-corrected. We also discuss the calibration of post-bomb (super 14) C samples and the available data sets and compilations, but do not give a recommendation for a particular data set.

Background measurements are provided for the period when Cariaco samples were run, as well as revisions leading to the most recent version of the floating varve chronology. The floating Cariaco chronology has been anchored to an updated and expanded Preboreal pine tree-ring data set, with better estimates of uncertainty in the wiggle-match. Pending any further changes to the dendrochronology, these results represent the final Cariaco 58PC calibration data set.

The "flatness" of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against (super 14) C dates. The calibration process, within such a confined age range, however, relies heavily on the structural accuracy of the calibration curve. We have therefore re-measured, at decadal intervals, a section of the Irish oak chronology for the period AD 495-725. These measurements have been included in IntCal04.

Each process is directly linked to a corresponding trapping mechanism: immiscible plume migration to hydrodynamic trapping, plume-water interaction to solubility trapping, and plume-mineral interaction to mineral trapping. In this study, reactive transport modelling of CO (sub 2) storage in a shale-capped sandstone aquifer at Sleipner has elucidated and established key parametric dependencies of these fundamental processes, the associated trapping mechanisms, and sequestration partitioning among them during consecutive ten-year prograde (active-injection) and retrograde (post-injection) regimes. Intra-aquifer permeability structure controls the path of immiscible CO (sub 2) migration, thereby establishing the spatial framework of plume-aquifer interaction and the potential effectiveness of solubility and mineral trapping. Inter-bedded thin shales, which occur at Sleipner, retard vertical and promote lateral plume migration, thereby significantly expanding this framework and enhancing this potential. Actual efficacy of these trapping mechanisms is determined by compositional characteristics of the aquifer and caprock: the degree of solubility trapping decreases with increasing formation-water salinity, whereas that of mineral trapping is proportional to the bulk concentration of carbonate-forming elements, principally Fe, Mg, Ca, Na and Al. In the near-field environment of Sleipner-like settings, 80-85% by mass of injected CO (sub 2) remains and migrates as an immiscible fluid phase, 15-20% dissolves into formation waters, and less than 1% precipitates as carbonate minerals. This partitioning defines the relative effectiveness of hydrodynamic, solubility, and mineral trapping on a mass basis. Seemingly inconsequential, mineral trapping has enormous strategic significance: it maintains injectivity, delineates the storage volume, and improves caprock integrity. Four distinct mechanisms have been identified: dawsonite [NaAlCO (sub 3) (OH) (sub 2) ] cementation occurs throughout the intra-aquifer plume, while calcite-group carbonate [principally (Fe,Mg,Ca)CO (sub 3) ] precipitate via disparate processes along lateral and upper plume margins, and by yet another process within inter-bedded and caprock shales. The coupled mineral dissolution/precipitation reaction associated with each mechanism reduces local porosity and permeability. For Sleipner-like settings, the magnitude of such reduction for dawsonite cementation is near negligible; hence, this process effectively maintains initial CO (sub 2) injectivity. Of similarly small magnitude is the reduction associated with formation of carbonate rind along upper and lateral plume boundaries; these processes effectively delineate the CO (sub 2) storage volume, and for saline aquifers anomalously rich in Fe-Mg-Ca may partially self-seal the plume. Porosity and permeability reduction is most extreme within shales, because their clay-rich mineralogy defines bulk Fe-Mg concentrations much greater than those of saline aquifers. In the basal caprock shale of our models, these reductions amount to 4.5 and 13%, respectively, after the prograde regime. During the retrograde phase, residual saturation of immiscible CO (sub 2) maintains the prograde extent of solubility trapping while continuously enhancing that of mineral trapping. At the close of our 20-year simulations, initial porosity and permeability of the basal caprock shale have been reduced by 8 and 22%, respectively. Extrapolating to hypothetical complete consumption of Fe-Mg-bearing shale minerals (here 10 vol.% Mg-chlorite) yields an ultimate reduction of about 52 and 90%, respectively, after 130 years. Hence, the most crucial strategic impact of mineral trapping in Sleipner-like settings: it continuously improves hydrodynamic seal integrity of the caprock and, therefore, containment of the immiscible plume and solubility-trapped CO (sub 2) .

We analyzed MH sediments from West Olaf Lake (WOL) and Steel Lake (SL) in Minnesota to examine the effects of warm/dry climatic conditions on prairie-woodland ecosystems. Mineral composition and carbonate 18O were used to determine climatic variations, whereas pollen assemblages, charcoal 13C, and charcoal accumulation rates were used to reconstruct vegetation composition, C3 and C4 plant abundance, and fire. The ratio of aragonite/calcite at WOL and 18O at SL suggest that pronounced droughts occurred during the MH but that drought severity decreased with time. From charcoal 13C data we estimated that the MH abundance of C4 plants averaged 50% at WOL and 43% at SL. At WOL C4 abundance was negatively correlated with aragonite/calcite, suggesting that severe moisture deficits suppressed C4 plants in favor of weedy C3 plants (e.g., Ambrosia). As climate ameliorated C4 abundance increased (from 33 to 66%) at the expense of weedy species, enhancing fuel availability and fire occurrence. In contrast, farther east at SL where climate was cooler and wetter, C4 abundance showed no correlation with 18O-inferred aridity. Woody C3 plants (e.g., Quercus) were more abundant, biomass flammability was lower, and fires were less important at SL than at WOL. Our results suggest that C4 plants are adapted to warm/dry climatic conditions, but not to extreme droughts, and that the fire regime is controlled by biomass-climate interactions.

(1) Numerous hydrostatic and uniaxial compaction experiments on pure, gas-saturated porous hydrate indicate that effective pressures approaching 100 MPa are required to fully compact sI methane hydrate and sII methane-ethane hydrate. This compares with effective compaction pressures of less than 1 MPa for the compaction of granular ice near its melting temperature. (2) Hydrate/sand aggregates synthesized by the ice-to-hydrate method are found to be more cohesive and durable that comparable ice/sand aggregates. This observation is consistent with experience in drill coring of hydrate/sand intervals compared with that in permafrost. (3) Triaxial compression tests indicate that sI methane hydrate and sII methane-ethane hydrate have ductile flow strengths that are 20 to 100 times stronger than ice under the same conditions, suggesting that their effects in increasing the strength of sediments may be larger than the effect of ice formation in arctic soils in producing permafrost. These results suggest that hydrates may have similar roles as the diagenetic minerals quartz and carbonates during lithogenesis. Such strengthening effects of hydrates in sediments should be lost during thermal decomposition. This weakening effect of hydrate decomposition is in addition to the pore-pressure effect of gas release. Hydrate decomposition is endothermic and rate controlled by heat flow at temperatures above above 0 C. These properties place severe limits on the conditions under which decomposition may be thermally and mechanically unstable.

The data were interpreted manually and with a computer algorithm. The algorithm interpretation was adjusted to be consistent with atmospheric methane stratigraphic ties to the GISP2 (Greenland Ice Sheet Project 2) ice core, (super 10) Be stratigraphic ties to the dendrochronology (super 14) C record and the dated volcanic stratigraphy. The algorithm interpretation is more consistent and better quantified than the tedious and subjective manual interpretation.

By comparing apatite fission-track ages with cosmogenic data, erosion rates in southern Tibet appear to be decelerating since the Miocene, whereas in the Kunlun, erosion rates have accelerated over the same timescale. Such secular changes suggest that the southern and central regions of the plateau had formed their present flat relief by the Pleistocene. Unusually high erosion rates along the northern margin of the plateau may reflect intense tectonic activity during the Holocene. These findings indicate that over much of the high plateau erosion rates are exceptionally low, and therefore the sources of detritus carried by the great Asian rivers that rise in Tibet lie overwhelmingly in bedrocks at lower altitudes. This study illustrates the potential of cosmogenic studies for unraveling the most recent phase of the erosion/exhumation history of orogenic belts that cannot be resolved by either Ar-isotope or fission-track thermochronometers.

We show that summits in the Torngat and Kaumajet mountains were covered by ice during the Last Glacial Maximum, and that their felsenmeer cover probably survived multiple glaciation events. For similar lithologies, soils on felsenmeer covered summits are signigicantly more weathered than those below the felsenmeer limit, displaying higher concentrations of crystalline iron, amorphous aluminium, and silicium extracted with oxalate. Secondary minerals such as gibbsite and kaolinite occur in felsenmeer soils, whereas those formed in till lacked these secondary minerals. (super 10) Be and (super 26) Al exposure ages for nine of ten samples, from high-elevation tors and autochthonous felsenmeer blocks, range from 73+ or -6 to 157+ or -15 ka. By contrast, ages of 11.4+ or -1.0 and 11.7+ or -1.0 ka are measured for bedrock in the much lower Saglek zone, indicating extensive (>3 m) glacial erosion of this zone during Late Wisconsinan glaciation. (super 26) Al/ (super 10) Be ratios demonstrate that exposure of the high-elevation surfaces was interrupted during at least one cosmic ray shielding event by either ice or till cover. In either case, Late Wisconsinan glaciers could not have extensively eroded these surfaces. Five erratics dated above the Saglek zone, including one in the felsenmeer zone, have exposure ages ranging from 11.6+ or -1.0 to 13.6+ or -0.7 ka. This indicates that valley and high-elevation ice persisted through the Younger Dryas Chron and provides further evidence that the highlands were not nunataks during the Late Wisconsinan period.

The specimen was collected from a drill core on the Huon Peninsula and has been independently dated with (super 230) Th. A site-specific reservoir correction has been applied to the results, and coral growth bands were used to calibrate individual growth years. Alternating density bands, which are the result of seasonal growth variations, were subsampled to provide 2 integrated 6-month (super 14) C measurements per year. This allows for 20 independent measurements to be averaged for each decadal value of the (super 14) C calibration, making these results the highest resolution data set available for this brief time range. The finestructure of the data set exhibits (super 14) C oscillations with frequencies on the order of 4 to 10 yr, similar to those observed in modern coral (super 14) C records.

The latter record was first published by Bard et al. (2004a,b), with the subsequent addition of some data by Shackleton et al. (2004). These data sets are compared with the IntCal98 record (Stuiver et al. 1998) and with data sets based on other archives, such as varves of Lake Suigetsu (Kitagawa and van der Plicht 1998, 2000), speleothems from the Bahamas (Beck et al. 2001), and Cariaco sediments (Hughen et al. 2004). Up to 26,000 cal BP, the Iberian Margin data agree within the errors of the other records. By contrast, in the interval between 33,000 and 41,000 cal BP, the Iberian Margin record runs between the Lake Suigetsu and Bahamian speleothem data sets, but it agrees with the few IntCal98 coral data and the Cariaco record.

The new calibration data sets extend an additional 2000 yr, from 0-26 cal kyr BP (Before Present, 0 cal BP = AD 1950), and provide much higher resolution, greater precision, and more detailed structure than IntCal98. For the Marine04 curve, dendrochronologically-dated tree-ring samples, converted with a box diffusion model to marine mixed-layer ages, cover the period from 0-10.5 cal kyr BP. Beyond 10.5 cal kyr BP, high-resolution marine data become available from foraminifera in varved sediments and U/Th-dated corals. The marine records are corrected with site-specific (super 14) C reservoir age information to provide a single global marine mixed-layer calibration from 10.5-26.0 cal kyr BP. A substantial enhancement relative to IntCal98 is the introduction of a random walk model, which takes into account the uncertainty in both the calendar age and the (super 14) C age to calculate the underlying calibration curve (Buck and Blackwell, this issue). The marine data sets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed here.

In this power plant, methane is combusted with oxygen in a gas generator to produce the working fluid for the turbines. The combustion produces a gas mixture composed of steam and carbon dioxide. These gases drive multiple turbines to produce electricity. The turbine discharge gases pass to a condenser where water is captured. A stream of pure carbon dioxide then results that can be used for enhanced oil recovery or for sequestration. The analysis considers a complete power plant layout, including an air separation unit, compressors and intercoolers for oxygen and methane compression, a gas generator, three steam turbines, a reheater, two preheaters, a condenser, and a pumping system to pump the carbon dioxide to the pressure required for sequestration. This analysis is based on a 400 MW electric power generating plant that uses turbines that are currently under development by a U.S. turbine manufacturer. The high-pressure turbine operates at a temperature of 1089 K (1500DGF) with uncooled blades, the intermediate-pressure turbine operates at 1478 K (2200DGF) with cooled blades and the low-pressure turbine operates at 998 K (1336DGF). The power plant has a net thermal efficiency of 46.5%. This efficiency is based on the lower heating value of methane, and includes the energy necessary for air separation and for carbon dioxide separation and sequestration.

The project exploits Internet browser technology and low-cost PC hardware, incorporates an Internet node, with access control, for depositing a minimal set of XML-based graphics files for presentation in an identical map format. Side-by-side viewing and televideo conferencing will permit rapid evaluation, data elaboration and recalculation (if necessary) and should produce strong consensus among decision makers. Successful completion affords easy utilisation by national/international organisations and non-nuclear states at risk of trans-boundary incursion.

To do this, the organism must invade and survive within both epithelial and endothelial cells. We have identified a facilitator of NTHi survival inside human cells, virulence-associated protein D (vapD sub(Hi), encoded by gene HI0450). Both vapD sub(Hi) and a flanking gene, HI0451, exhibit the genetic and physical characteristics of a toxin/antitoxin (TA) locus, with VapD sub(Hi) serving as the toxin moiety and HI0451 as the antitoxin. We propose the name VapX sub(Hi) for the HI0451 antitoxin protein. Originally identified on plasmids, TA loci have been found on the chromosomes of a number of bacterial pathogens, and have been implicated in the control of translation during stressful conditions. Translation arrest would enhance survival within human cells and facilitate persistent or chronic mucosal infections. Isogenic mutants in vapD sub(Hi) were attenuated for survival inside human respiratory epithelial cells (NCI-H292) and human brain microvascular endothelial cells (HBMEC), the in vitro models of mucosal infection and the blood-brain barrier, respectively. Transcomplementation with a vapD sub(Hi) allele restored wild-type NTHi survival within both cell lines. A PCR survey of 59 H. influenzae strains isolated from various anatomical sites determined the presence of a vapD sub(Hi) allele in 100% of strains. Two isoforms of the gene were identified in this population; one that was 91 residues in length, and another that was truncated to 45 amino acids due to an in-frame deletion. The truncated allele failed to transcomplement the NTHi vapD sub(Hi) survival defect in HBMEC. Subunits of full-length VapD sub(Hi) homodimerized, but subunits of the truncated protein did not. However, truncated protein subunits did interact with full-length subunits, and this interaction resulted in a dominant-negative phenotype. Although Escherichia coli does not contain a homologue of either vapD sub(Hi) or vapX sub(Hi), overexpression of the VapD sub(Hi) toxin in trans resulted in E. coli cell growth arrest. This arrest could be rescued by providing the VapX sub(Hi) antitoxin on a compatible plasmid. We conclude that vapD sub(Hi) and vapX sub(Hi) may constitute a H. influenzae TA locus that functions to enhance NTHi survival within human epithelial and endothelial cells.

Gene network models are needed to interpret the resulting large and complex data sets. Rationally designed perturbations (e.g., gene knock-outs) can be used to iteratively refine hypothetical models, suggesting an approach for high-throughput biological system analysis. We introduce an approach to gene network modeling based on a scalable linear variant of fuzzy logic: a framework with greater resolution than Boolean logic models, but which, while still semi-quantitative, does not require the precise parameter measurement needed for chemical kinetics-based modeling. Results: We demonstrated our approach with exhaustive search for fuzzy gene interaction models that best fit transcription measurements by microarray of twelve selected genes regulating the yeast cell cycle. Applying an efficient, universally applicable data normalization and fuzzification scheme, the search converged to a small number of models that individually predict experimental data within an error tolerance. Because only gene transcription levels are used to develop the models, they include both direct and indirect regulation of genes. Conclusions: Biological relationships in the best-fitting fuzzy gene network models successfully recover direct and indirect interactions predicted from previous knowledge to result in transcriptional correlation. Fuzzy models fit on one yeast cell cycle data set robustly predict another experimental data set for the same system. Linear fuzzy gene networks and exhaustive rule search are the first steps towards a framework for an integrated modeling and experiment approach to high-throughput "reverse engineering" of complex biological systems.

For a porous aggregate medium such as granular tuff, the total water content is comprised of surface water and interior water. The surface water component (water film around grains and pendular water between the grain contacts) could serve as a predominant diffusion pathway. To investigate the extent to which surface water films and contact points affect solute diffusion in unsaturated gravel, we examined the configuration of water using X-ray computed tomography (CT) in partially saturated gravel and made quantitative measurements of diffusion at multiple water contents using two different techniques. In the first, diffusion coefficients of KCl in 2- to 4-mm granular tuff at multiple water contents were calculated from electrical conductivity (EC) measurements using the Nernst- Einstein equation. In the second, we used laser ablation with inductively coupled plasma-mass spectrometry (LA/ICP-MS) to perform microscale mapping, allowing the measurement of diffusion coefficients for a mixture of chemical tracers for tuff cubes and tetrahedrons having two contact geometries (cube-cube and cube-tetrahedron). The X-ray computed tomography images show limited contact between grains, and this could hinder the pathways for diffusive transport. Experimental results show the critical role of surface water in controlling transport pathways and hence the magnitude of diffusion. Even with a bulk volumetric water content of 1.5%, the measured solute diffusion coefficient is as low as 1.5 x 10 super(-14) m super(2) s super(-1) for tuff gravel.

The test was carried out under conditions simulating those expected during actual remediation of a single shell tank located at the U. S. Department of Energy Hanford Reservation, Washington. A system was developed for the experiment to allow remote operation during the entire test. Approximately 54,000 liters of concentrated sodium thiosulfate (simulating tank waste) were episodically released from a steel tank in a blind test lasting 110 days (no knowledge of the release episodes during the course of the test were provided). ERT data were collected using an array of point electrodes installed in boreholes around the tank. Each day during the test a leak or no-leak condition was declared based solely on analysis of the electrical data. The success rate of the declarations made during the test was only 57%, however, further analysis carried out at the end of the test resulted in a significant improvement of the success rate. The results suggest that ERT, used either with custom built electrode arrays or existing steel cased wells, can provide an effective means of monitoring remediation or long-term integrity of underground storage tanks.

AN - 71453325; 14642568 AB - Xrcc1 knockout embryos show increased DNA breakage and apoptosis in tissues of the embryo proper prior to death at embryonic day E6.5. An additional deficiency in Trp53 allows Xrcc1(-/-) embryos to enlarge slightly and initiate gastrulation although ultimately death is delayed by less than 24h. Death presumably results from DNA damage that reaches toxic levels in the post-implantation mouse embryo. To investigate the level of XRCC1 protein needed for successful mouse development, we derived Xrcc1 transgene-complemented Xrcc1(-/-) mice that express Xrcc1 within the normal range or at a greatly reduced level (<10% normal). The greatly reduced XRCC1 protein level destabilized the XRCC1 partner protein DNA ligase III (LIG3) but still allowed for successful mouse development and healthy, fertile adults. Fibroblasts from these animals exhibited almost normal alkylation sensitivity measured by differential cytotoxicity. Thus, a large reduction of both XRCC1 and DNA ligase III has no observable effect on mouse embryogenesis and post-natal development, and no significant effect on cellular sensitivity to DNA alkylation. The presence of XRCC1, even at reduced levels of expression, is therefore capable of supporting mouse development and DNA repair.

AN - 71511927; 14710934 AB - The sorption of uranium on to Ordinary Portland Cement (OPC)/Pulverized Fuel Ash (PFA, fly ash) grout material has been investigated with respect to time, pH, grout:uranium ratio and the chemical composition of the supporting solution. The information obtained is of relevance to the disposal of low-level nuclear waste. The grout material has been chemically characterised and is negatively charged above pH 2.3. At the uranium concentrations studied (2 microM) all uranyl hydroxide aqueous species are expected to be monomeric, rather than polymeric. Uranium(VI) sorption on to the grout material has been explained in terms of inner sphere complexation binding by means of hydroxide bridge formation between the uranium and grout surface. It is also proposed that oligomeric uranyl species are formed across the grout surface, perhaps stabilising the repulsive effects of the negatively charged grout surface and anionic uranyl hydroxide species. Thermodynamic modelling has been used to explain the sorption variation versus solution pH and identifies potential binding mechanisms.

The purpose of this study is to determine the origin and history of waters associated with the formation, using long-lived cosmogenic and stable isotope systems. Ratios of (super 129) I/I and stable isotope values (delta D and delta (super 18) O) were determined in waters from close to 100 wells, (super 36) Cl/Cl ratios for a subset of these samples. A significant group of samples has (super 129) I/I ratios between 100X10 (super -15) and 200X10 (super -15) , indicating minimum iodine ages close to 60 Ma. If these ages are corrected for the addition of fissiogenic (super 129) I, they are compatible with the depositional age of the Fruitland Formation (Late Cretaceous). Several sets of waters are clearly present within the data. A group dominated by infiltration of recent surface waters is restricted to the uplifted basin margins, with a lateral extent of less than 5 km from outcrop, and is characterized by (super 129) I/I ratios in excess of 1500X10 (super -15) and meteoric delta D, delta (super 18) O, and (super 36) Cl/Cl signatures. The rest of the basin is characterized by several subsets of formation waters which have undergone variable degrees of iodine enrichment through diagenesis as well as variable degrees of dilution. The first subgroup is found in coals of relatively low vitrinite reflectance and moderate enrichment of iodine. This subgroup predominantly consists of entrapped pore fluids, although it may also contain waters which infiltrated the coals at the time of the Laramide uplift, between 25 and 30 Ma. A second subgroup consists of formation waters associated with coals of high vitrinite reflectance. Despite subsequent uplift, the high iodine concentrations and low (super 129) I/I ratios of this subgroup, as well as a moderate depletion of deuterium relative to (super 18) O, suggest that these waters were not significantly altered since the time when diagenetic reactions occurred in the deepest portion of the basin. A third subgroup, with higher delta D and delta (super 18) O values as well as higher (super 129) I/I ratios, extends roughly west to east at the New Mexico-Colorado state line and corresponds to a region of extensive fracturing of the coalbeds. In this case, the higher (super 129) I/I ratios are probably due to contributions of fissiogenic (super 129) I through fracture flow, perhaps from deeper formation waters. Our results do not support models of subsequent basin-wide groundwater migration in the Fruitland Formation. The combined use of (super 129) I and (super 36) Cl with stable isotope studies provides valuable information as to the hydrologic history of coalbed methane deposits, as well as their potential for commercial exploitation.

Recently, permanent electrode arrays have been installed at a number of sites as a means of long term monitoring of the integrity of a landfill liner. There has, however, been no scientific study to date which addresses the performance of such systems. Here, we utilise a physical scale model of a landfill liner/cap and investigate the usefulness of grid based and boundary electrode arrays for detecting multiple leaks in a landfill liner or cap. We compare the two electrode geometries under a series of controlled electrical leak experiments and demonstrate how both these arrangements can detect and locate leaks in a geomembrane. We also demonstrate some of the limitations of the method. For example, present data processing schemes can give misleading results when there are multiple leaks. The influence of variation in resistivity of the soil above or below the liner and also boundary current leakage on the performance of the technique is also studied. The results suggest that these two factors, unless they are accounted for, can have a significant impact on the results and subsequently affect the practical value of electrical leak detection systems.

The experimental results indicate a strong dependence of the effective Cs super(+) K sub(d) on the concentrations of other cations, including Na super(+) that is present at high to extremely high concentrations in fluids leaking from the Hanford SX tanks. A strong dependence of the Cs super(+) K sub(d) on the aqueous Cs super(+) concentration is also apparent, with retardation of Cs super(+) increasing from a value of 41 at a Cs super(+) concentration of 10 super(-4) M in the feed solution to as much as 282 at a Cs super(+) concentration of 5x10 super(-7) M, all in a background of 1 M NaNO sub(3). The total cation exchange capacity (CEC) of the Hanford sediment was determined using super(22)Na isotopic equilibrium exchange in a flow-through column experiment. The value for the CEC of 120 mu eq/g determined with this method is compatible with a value of 121.9 mu eq/g determined by multi-cation elution. While two distinct exchange sites were proposed by Zachara et al. [Geochim. Cosmochim. Acta 66 (2002) 193] based on binary batch exchange experiments, a third site is proposed in this study to improve the fit of the Cs super(+)-Na super(+) and Cs super(+)-Ca super(+) exchange data and to capture self-sharpened Cs super(+) breakthrough curves at low concentrations of Cs super(+). Two of the proposed exchange sites represent frayed edge sites (FES) on weathered micas and constitute 0.02% and 0.22% of the total CEC. Both of the FES show a very strong selectivity for Cs super(+) over Na super(+) (K sub(Na-Cs)=10 super(7.22) and 10 super(4.93), respectively). The third site, accounting for over 99% of the total CEC, is associated with planar sites on expansible clays and shows a smaller Na super(+)- Cs super(+) selectivity coefficient of 10 super(1.99). Parameters derived from a fit of binary batch experiments alone tend to under predict Cs super(+) retardation in the column experiments. The transport experiments indicate 72-90% of the Cs super(+) sorbed in experiments targeting exchange on FES was desorbed over a 10- and 24- day period, respectively. At high Cs super(+) concentrations, where sorption is controlled primarily by exchange on planar sites, 95% of the Cs super(+) desorption was desorbed. Most of the difficulty in desorbing Cs super(+) from FES is a result of the extremely high selectivity of these sites for Cs super(+), although truly irreversible sorption as high as 23% was suggested in one experiment. The conclusion that Cs super(+) exchange is largely reversible in a thermodynamic sense is supported by the ability to match Cs super(+) desorption curves almost quantitatively with an equilibrium reactive transport simulation. The model for Cs super(+) retardation developed here qualitatively explains the behavior of Cs super(+) in the Hanford vadose zone underneath a variety of leaking tanks with differing salt concentrations. The high selectivity of FES for Cs super(+) implies that future desorption and migration is very unlikely to occur under natural recharge conditions.

The amounts of MeIQx, DiMeIQx, IFP, and PhIP in the liquid portion of the digestate were compared to levels in the undigested meat to determine the percentage released (accessible fraction). Incubating the meat with amylase and pepsin did not change the accessibility of HAs when compared to incubation with water alone. In contrast, increasing amounts of pancreatin increased the accessibility up to 6.4-fold. Comparing the amounts of the HAs in the liquid to the solid fraction showed that there was more MeIQx, DiMeIQx, and IFP in the liquid fraction. In contrast, PhIP was equally divided between the solid and liquid fractions. For all four compounds, increasing the doneness of the meat decreased the amount of the compound accessible from the meat matrix. Our data suggest that bioaccessability of HAs may vary according to the polarity of the individual HAs and also may depend upon the doneness of the meat. These results may have important ramifications for human feeding studies, which assume that the total amount of each HA in the meat matrix is equally bioavailable.

From 1953 to 1999 delta super(13)C decreased by 0.9ppt. Pre-bomb delta super(14)C is-59ppt, consistent with coral based estimates from the same region and the post-bomb maximum (+121ppt) is achieved in 1973. A 1-D box-diffusion model was employed to quantify vertical diffusivity and air- sea exchange rates. The model suggests that a low vertical diffusion rate (0.1 cm super(2) s super(-1)) coupled with a moderate CO sub(2) exchange rate produces the overall observed shape of the pre-post bomb delta super(14)C record and the general large scale features of the delta super(13)C time series. These parameters are on the low end of values used in ocean-carbon GCMs but are consistent with microscale tracer experiments.

Recently developed detection and identification systems are characterized by increased sensitivity, greater automation, and fewer false alarms. Attempts are also under way to reduce the cost and complexity of field-deployable systems. A broad range of decontamination reagents for equipment and personnel is emerging, but decontamination of large buildings, inaccessible spaces, and sensitive equipment remains problematic.

AN - 71332087; 14596589 AB - Amyloid beta 1-42 (Abeta(1-42)) is a self-associating peptide that becomes neurotoxic upon aggregation. Toxicity originally was attributed to the presence of large, readily formed Abeta fibrils, but a variety of other toxic species are now known. The current study shows that Abeta(1-42) can self-assemble into small, stable globular assemblies free of fibrils and protofibrils. Absence of large molecules was verified by atomic force microscopy (AFM) and nondenaturing gel electrophoresis. Denaturing electrophoresis revealed that the globular assemblies comprised oligomers ranging from trimers to 24mers. Oligomers prepared at 4 degrees C stayed fibril-free for days and remained so when shifted to 37 degrees C, although the spectrum of sizes shifted toward larger oligomers at the higher temperature. The soluble, globular Abeta(1-42) oligomers were toxic to PC12 cells, impairing reduction of MTT and interfering with ERK and Rac signal transduction. Occasionally, oligomers were neither toxic nor recognized by toxicity-neutralizing antibodies, suggesting that oligomers could assume alternative conformations. Tests for oligomerization-blocking activity were carried out by dot-blot immunoassays and showed that neuroprotective extracts of Ginkgo biloba could inhibit oligomer formation at very low doses. The observed neurotoxicity, structure, and stability of synthetic Abeta(1-42) globular assemblies support the hypothesis that Abeta(1-42) oligomers play a role in triggering nerve cell dysfunction and death in Alzheimer's disease.

We compare the climatic response to increased greenhouse gases of the National Center for Atmospheric Research (NCAR) climate model, CCM3, at T42 and T170 resolutions (horizontal grid spacing of 300 and 75km respectively). All simulations use prescribed sea surface temperatures (SST). Simulations of the climate of 2100 ad use SSTs based on those from NCAR coupled model, Climate System Model (CSM). We find that the global climate sensitivity and large-scale patterns of climate change are similar at T42 and T170. However, there are important regional scale differences that arise due to better representation of topography and other factors at high resolution. Caution should be exercised in interpreting specific features in our results both because we have performed climate simulations using a single atmospheric general circulation model and because we used with prescribed sea surface temperatures rather than interactive ocean and sea-ice models.

Cosmogenic radionuclide and optically stimulated luminescence dating indicates that two glacial advances occurred in marine isotope stage (MIS)-3 and MIS-2. In the Anyemaqen Mountains, a third advance occurred in the Early Holocene. We suggest that glaciation was synchronous in the Anyemaqen and Nianbaoyeze Mountains, as well as in other glaciated areas of Tibet and the Himalaya that are influenced by the Asian monsoon. The maximum extent of glaciation occurred early in the last glacial cycle (MIS-3) during a time of increased insolation when the monsoon intensified and supplied abundant precipitation, as snow at high altitude, to feed high-altitude glaciers. This suggests that precipitation, as snow, is fundamental in controlling glaciation in these regions. However, the occurrence of glacial advances during the insolation minimum of MIS-2 suggests that, despite reduced precipitation at this time, the annual temperatures were cold enough to maintain positive glacier mass balances. The numerically defined chronologies for the Anyemaqen and Nianbaoyeze Mountains presented here provide a framework for comparing glacial advances in other parts of high Asia.

The results indicate rapid alluvial transport with minimal alluvial storage and suggest that most of the cosmogenic nuclide inventory in sediments is accumulated while they are eroding from bedrock and travelling down hill slopes. Spatially homogeneous erosion rates of 25- 30 mm/ka are calculated throughout the Great Smoky Mts. It is concluded that rates of erosion for the Appalachians integrated over varying time periods from decades to 100 Ma are similar, the result of equilibrium between erosion and isostatic uplift in the region.

Glaciation in this region is controlled by two major climatic systems: the mid-latitude westerlies and the South Asian monsoon. In addition, significant interannual climatic variability in the region is associated with El Nino-Southern Oscillation. Furthermore, glaciation is strongly influenced by topographic constraints. The glacial system provides water for hundreds of millions of people in central Asia, and variations in the glacial and associated hydrological systems have profound socio-economic and political consequences. Yet despite the regional and global importance of glaciation in High Asia, the dynamics, extent and timing of Late Quaternary glaciation in this region are poorly understood and defined. This is particularly so for the last glacial-interglacial transition. To examine the nature of glacier oscillations, key areas throughout the Himalaya and Tibet were studied using glacial geomorphic mapping, sedimentology, and cosmogenic radionuclide (CRN) surface exposure and optically stimulated luminescence (OSL) dating techniques to define the timing and extent of Late Quaternary glaciation. These studies show a strong monsoonal influence on glaciation, synchroneity of glaciation throughout the region and strong topographic constraints on extent of glaciation. Furthermore, it is evident that glaciation was restricted in extent during the global Last Glacial Maximum (LGM), contrasting with extensive advances during insolation maximum in early part of the last glacial cycle. Nevertheless, notable glacial advances occurred during latter part of the LGM ( approximately 15-16 ka), the Lateglacial Interstadial, and the early Holocene. These glacial advances were most extensive in the monsoon-influenced regions and may have even been more extensive than the LGM advance. The results suggest that glaciation throughout Tibet and the Himalaya is controlled by precipitation changes related to oscillations in the southwest Asian monsoonal system combined with cooling that is broadly coincident with the global cooling cycles.

A significant component of this dextral shear is accommodated along the Owens Valley-White Mountains fault system. A published kinematic model for the Eastern California Shear Zone suggests that 1.4-4.1 mm/yr of Owens Valley fault slip continues northward along the White Mountains fault zone. New geologic mapping, geomorphic, and geochronologic investigations along the White Mountains fault zone shed light on its Quaternary dextral fault slip history and allow us to test this kinematic model. Drainages, shutter ridges, and ridgelines show dextral offsets that range from approximately 5 to 559+ or -7 meters. Beryllium-10 cosmogenic radionuclide dating methods used on in situ boulders demonstrate that the age of the oldest fan surface is 225+ or -25 ka. Minimum offset of drainages developed within the oldest fan surface is 559+ or -7 meters, yielding a minimum late Pleistocene slip rate of 2.5+ or -0.3 mm/yr. Our new data refine a kinematic model proposed for the recent evolution of dextral fault slip in the Eastern California Shear Zone.

Sample sites are at an altitude of 2100 to 2300 m. Stable isotope analyses are used to assess the contribution of cool and warm season precipitation to the recharge budget, and to evaluate the timing and extent of evaporation during recharge. Cool season precipitation (mostly snowfall) accounts for 75 to 80% of the annual precipitation total, and has an average deuterium value that is 40 to 70 permil lighter than average summer rainfall. Perched mountain springs located near each precipitation gauge show small isotopic variations over time (generally less than 5 permil), and are reasonable proxies for average local recharge. Comparison of the stable isotope data for precipitation and springs suggests more than 90% of recharge originates from cool season precipitation. Three of the four springs show isotopic evidence of moderate evaporation, inferred to occur during recharge. Shallow soil infiltration samples collected in lysimeters show variations in infiltration amount from year-to-year, independent of the total precipitation amount. The rate at which the snowpack melts may be a key control on the net infiltration flux. Smaller net infiltration volumes tend to show large evaporation effects whereas larger volumes show little evidence of significant evaporation. Water vapor loss through the soil zone during slow infiltration is inferred to be the dominant control on evaporation during recharge. This work was funded by the Hydrologic Resources Management Program, National Nuclear Security Administration, Nevada Site Office, and was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under contract number W-7405-Eng-48.

Cosmogenic dating ( (super 10) Be and (super 26) Al) of boulders on moraines in valleys bordering the Junin Plain in the central Peruvian Andes (ca. 11 degrees S, 76 degrees W, altitude 4100 m) and in the Cordillera Real of the Bolivian Andes (ca. 16 degrees 16'S, 68 degrees 9'W, altitude 4600 m) indicates that the local last glacial maximum likely occurred during oxygen isotope stage 2, but prior to the inferred peak of Northern Hemisphere continental glaciation (approximately 21,000 calendar years BP). The moraines deposited by older glaciations in the study areas are substantially larger and extend farther downvalley than those of the local last glacial maximum. We have been studying snowline depression at the last glacial maximum in tropical South America. Modern snowline in the region has been estimated from remaining small ice caps and geomorphic evidence at approximately 4800-5000 m. Valleys in the study area bordering the Junin Plain are relatively shallow, having a maximum difference in altitude between headwall and mouth of about 700 m (Alcacocha Valley). This shallow profile constrains snowline depression. Our estimate of the snowline at the local last glacial maximum in Alcacocha Valley is approximately 4600 m, indicating a relatively small snowline depression of about 200-400 m. Estimates of snowline at the last glacial maximum elsewhere in tropical South America range from about 300 m to more than 1000 m, but the related deposits typically have not been dated directly. Few, if any, moraines in tropical South America have been tightly constrained in age to the last glacial maximum of the Northern Hemisphere, or even to a local last glacial maximum. Our results, which include direct dating of moraines from the local last glacial maximum and from previous glaciations, make a fundamental contribution to paleoclimate reconstruction efforts in the tropics.

Disequilibrium in this ratio in a sample implies a complex history of exposure and burial. Measurement of Be-10 and Al-26 in quartz from bedrock surfaces throughout the Ford Ranges, West Antarctica, reveals a history of exposure, burial beneath the West Antarctic Ice Sheet, and survival against sub-glacial erosion. Except for low-altitude surfaces heavily scoured by the ice sheet, all surfaces display disequilibrium in the ratio of Al-26 to Be-10 and have apparent exposure ages significantly older than Holocene deglaciation. The data show that: (1) Effective exposure time increases with altitude on each mountain, (2) The ratio of time-exposed to time covered by ice decreases with altitude on each mountain and roughly decreases inland, (3) Minimum overall burial times range from hundreds of thousands to approximately 3.5 million years, and (4) Maximum limits on the fraction of time-exposed (compared to the time covered by ice) for these samples are as low as 1-5%. These results are consistent with survival of the surfaces through repeated Plio-Pleistocene glaciations, and indicate that the present deglaciation of West Antarctica is among the most extensive in the mid- to late-Quaternary. Bedrock in the Ford Ranges is variably weathered, from clean, glacially abraded surfaces at low altitude, to weathered surfaces at high altitude, showing surficial oxidation, salt and gruss accumulation, widened joints and rounded corners. Our data show that weathered features at high altitude are the result of repeated exposure and glaciation, rather than continuous sub-aerial weathering.

However, interpretations of bulk fluid-calcite experiments in the literature disagree upon the most fundamental assumptions regarding the influences of temperature, growth rate, impurity concentration, and salinity on Mg uptake. To begin addressing this problem, we conducted a new type of calcite growth study: while temperature and solution chemistry were precisely controlled, we directly quantified near-equilibrium, layer-mechanism growth rates and Mg contents of calcite crystals. We measured migration rates of monomolecular steps in situ on individual growth spirals on {104} calcite faces using atomic force microscopy. Solutions containing CaCl (sub 2) , NaHCO (sub 3) , MgCl (sub 2) , and 0.1 molal NaCl flowed continuously over samples. Growth rates were determined at 15-30 degrees C in solutions containing 0-10 (super -4) molal [Mg] and with supersaturations (ln [(aCa++XaCO3--)/Ksp]) of 0.3-1.0. In complementary experiments, we grew seed crystals under identical conditions for several days to produce large growth hillocks for high-resolution electron microprobe analysis. We find that Mg exhibits a pronounced, non-uniform partitioning into growth hillocks with a distinct preference for geometrically obtuse steps ( approximately 100 to >3000 ppm) over acute steps (0 to approximately 800 ppm). This partitioning is opposite to results of Paquette and Reeder (1995; GCA 59:735) for calcite grown at high ionic strength (1-2 molal) with multiple impurities in solution. Our work suggests that the interaction of Mg with calcite surfaces depends upon nanoscale site geometry and also upon the presence or absence of other trace elements. Preliminary findings suggest that of the factors named above, supersaturation has the strongest influence on Mg/Ca in the solid crystals. Our work on inorganic controls of impurity partitioning in calcite sets the stage for investigation of biological effects and for robust interpretation of trace element signatures in biogenic calcite.

Previous studies show that the form and chemistry of biogenic carbonates are affected by factors such as temperature, salinity, water turbidity and dissolved oxygen. To complicate these relationships, complex biological processes, termed "vital effects", also influence the compositions of skeletal materials during mineral formation. Quantifying molecular-scale controls on mineralization in the absence of "vital effects" is essential to sorting out the principles that control compositional signatures of biogenic carbonates. Here we use in situ atomic force microscopy to observe directly the molecular scale effects of Sr on layer growth of abiotic calcite and couple these insights with quantitative measurements of the kinetics and thermodynamics of growth. Strontium inhibits calcite growth by different mechanisms for positive (larger, geometrically more open kink sites) and negative (smaller and more shielded kink sites) surface coordination environments that characterize calcite step edge directions. Low concentrations of strontium enhance the rate of calcite growth through changes in kinetics. A new conceptual model is introduced to explain this behavior. Higher concentrations of strontium inhibit and ultimately stop calcite growth by a step blocking mechanism. The critical supersaturation required to initiate growth increases with increasing levels of strontium. At higher supersaturations, strontium causes growth rates to increase to levels greater than those for the pure system. The step blocking model proposed by Cabrera and Vermilyea (1958) does not predict this experimental behavior. Preliminary evidence indicates that strontium is preferentially incorporated into the positive step directions, and impurity concentrations are not homogeneous throughout the structure. This study demonstrates that strontium and magnesium have different surface interaction mechanisms, showing the importance of understanding growth processes at the nanoscale. We reiterate the significance of interpreting impurity signatures within the framework of step-specific interactions that occur during mineralization.

Less data are available regarding changes in longer, decadal-scale climate cycles through the Holocene. We present sedimentologic, geochemical, and image analysis data from annually laminated Derby Lake, Michigan (43 degrees 16'15"N lat., 85 degrees 7'30"W lon.) suggesting similar changes in decadal-scale variability occurred during the Mid-Holocene. Decadal-scale cycles are expressed in Derby Lake sediment as changes in the carbonate content, with carbonate alternating between high values (40-80%) and low values (<10%) for periods of a few years to multiple decades. Transitions between carbonate-rich and carbonate-depleted sediments are typically abrupt, occurring within 1 to 10 varve years, and form visually striking cm-scale bundles of light carbonate-rich laminations and dark carbonate-depleted laminations. These cycles are documented visually, as well as quantified in sediment grayscale intensity, carbon coulometry, and stable isotope data. Beginning in the early Holocene (8400 cal yr BP), Derby Lake varves were dominantly carbonate rich, with some carbonate depletion events occurring around 8200 cal yr BP. A period of low lake level followed, and Mid-Holocene Derby Lake sediments are dominated by elevated carbonate abundance, and a paucity of carbonate depletion events. Beginning gradually after 5300 cal yr BP, carbonate depletion events recur and continue to increase in frequency and intensity until 1500 cal yr BP, where cycles begin to taper off, with a final carbonate-depletion cycle ending in the Little Ice Age. We suggest that carbonate-depletion cycles are environmentally driven phenomena reflecting changes in decadal-scale climatic variability in Michigan through the Holocene. Links to the Pacific ocean-atmosphere system are suspected drivers in these changes, and the phenomena may also be linked to similar changes observed in the ENSO system during these times.

The older Mattole terraces have higher proportions of unsaturated alkyl and aromatic carbon groups than the more recently formed terraces. Precipitation at Mattole is nearly double that at Santa Cruz which results in increased weathering of parent material. Our NMR results suggest that weathering patterns shape the specific types of carbon stored within the soil mineral matrix.

The majority of water samples are very dilute and are predominantly steam that condensed in the sampling lines. A few samples with up to approximately 80 ppm Cl may contain rock-pore fluids. Suites of water samples with distinctive compositions were collected from packed-off intervals in two boreholes. These generally low-pH samples contained large amounts of Cl (up to 1,250 ppm) and SO (sub 4) (up to 821 ppm), plus detectable Cr, Mn, Ni, and Zn. The neoprene (polychloroprene) packers were considered possible sources of fluid modification, because they contain both Cl and S. Steel components of the packers are possible sources of the transition metals. Two types of heating tests were performed on neoprene and tuff samples. In the flow-through test, air was circulated through test cells with ground samples of neoprene or tuff or through an empty test cell at 190, 130, and 90 degrees C. The air was then bubbled through water to extract soluble volatile species. Water samples associated with neoprene contained elevated chloride (up to 18,791 ppm) and sulfate (up to 155 ppm) and had lower pH than samples from the other test cells. More acidic and higher chloride samples were collected from neoprene at higher temperature. In follow-up tests at lower temperatures, detectable lowering of pH due to neoprene degradation was noted at temperatures as low as 59 degrees C, with a pronounced pH effect at 71 degrees C. Boiling-water tests contacted tuff or neoprene directly with boiling water for eight days. The pH of water with tuff was buffered by tuff-gas reactions. For water with neoprene, the pH was not strongly affected, yet chloride (up to 339 ppm) and sulfate (up to 55 ppm) were produced. In the flow-through test, oxygen was readily available, resulting in the generation of HCl from the oxidized neoprene. In the boiling test, the oxygen concentration was insufficient for much oxidation of neoprene to occur. The tests show that generation of Cl-rich low pH waters may occur in borehole intervals at sub-boiling and near-boiling temperatures with temperature gradients within the packed intervals.

Ratios greater than 1,250X10 (super -15) were previously reported from the northern Exploratory Studies Facility (ESF) tunnel and were interpreted to have a bomb-pulse source indicating percolation to depths of 200 to 300 m below land surface in the last 50 years. In contrast, samples from the southern ESF had (super 36) Cl/Cl ratios near the Holocene meteoric value of 500X10 (super -15) , despite generally similar hydrogeologic conditions. Attempts to reproduce high ratios yielded mixed results. To resolve the issue, the U.S. Department of Energy requested an independent validation study (VS), organized by the U.S. Geological Survey, to corroborate the presence of bomb-pulse (super 36) Cl/Cl ratios. The VS used core primarily from 4-m-long boreholes drilled across a fractured zone where 11 of 18 ESF tunnel-wall samples and 8 of 10 core samples were previously reported to have bomb-pulse (super 36) Cl/Cl ratios. New VS samples were crushed and sieved between 2- and 19-mm screens and passively leached for 1 hr in deionized water. Leaching experiments showed that small variations in grain size and leach times had only minor effects on soluble Cl extractions. The short leach time resulted in low Cl concentrations and large (super 36) Cl/Cl errors, but maximized the probability of detecting bomb-pulse (super 36) Cl/Cl signatures. Leachates of 40 VS samples had a mean Cl concentration of 0.141 (+ or -0.026 2Xstandard error) mg/kg rock and a mean (super 36) Cl/Cl ratio of 337 (+ or -45 2Xstandard error)X10 (super -15) (range of 137 to 717X10 (super -15) ). Low Cl concentrations that do not correlate with (super 36) Cl/Cl ratios are consistent with a single, low- (super 36) Cl/Cl meteoric Cl source rather than mixtures of bomb-pulse and rock (or other) sources. Thus, the VS did not independently corroborate earlier results despite efforts to maximize extraction of bomb-pulse Cl and efforts to use core from some of the same boreholes used previously. Differences in sampling, leaching, and analysis are not likely causes for the discrepancies.

The experimental results indicate a strong dependence of the effective Cs+ Kd on the concentrations of other cations, including Na+, which is present at high to extremely high concentrations in fluids leaking from the Hanford SX tanks. The data not only show a dependence of the Cs+ Kd with regard to the aqueous Cs+ concentration, but also with temperature. The focus of this presentation will be on the temperature effect of cesium exchange on Hanford sediments. At 80 degrees C, cesium mobility is about 2 times higher than at 25 degrees C for solutions of similar composition. At low cesium concentrations (5 X 10-7M) cesium retardation increases from Rd = 117 at 80 degrees C to Rd = 282 at 25 degrees C. Similar trends are observed at higher cesium concentrations and higher salt solutions. In 1 M NaNO3 and 10-4M Cs solutions, we report Cs Rd = 17 at 80 degrees C and Rd = 41 at 25 degrees C. In higher salt solutions that are more representative of tank liquours (7.5 M NaNO3) 10-4 M Cs is retarded by a factor of 4 at 80 degrees C and a factor of 8 at 25 degrees C. The decrease in retardation with increasing temperature may be attributed to solution chemistry temperature effects as well as temperature effects of the ion exchange reaction. We will employ Pitzer thermodynamic database together with our multi-site cation exchange model to determine contributions from solution chemistry and ion exchange with the Hanford sediments.

These, and additional new magnetostratigraphic data presented here, derive from drill cores penetrating the Cold Creek flood bar in the Pasco Basin, a depositional sink for much of the material scoured from the Channeled Scabland during Missoula Floods and other similar events. The eastern part of the Cold Creek bar records a magnetostratigraphy characterized by reversed polarity at the base with normal polarity above and reversed polarity on top. We hypothesize that the normal zone is the Jaramillo subchron (0.99-1.07 Ma), or less likely, the Olduvai subchron (1.77-1.95 Ma). We test these possibilities by cosmogenic burial dating (Granger and Musikar, 2001), using the differential radioactive decay of (super 26) Al and (super 10) Be. We sampled 2 paleosols from drill cores of eastern Cold Creek bar as well as 14 kyr Missoula Flood sediments from Badger Coulee for cosmogenic burial dating. We chose the paleosols to increase the likelihood that sufficient cosmogenic nuclides would have accumulated in the samples prior to burial to allow application of this technique. We analyzed the 14 kyr sample to provide an estimate of the inherited cosmogenic nuclide ratio. Measurable inherited concentrations in the same proportion as that produced at the surface would indicate that burial dating could be applied throughout the stratigraphy. If not, then only the paleosols should be dated by this technique. Initial results suggest that sufficient cosmogenic nuclides concentrations are present in these sediments to make burial dating feasible.

Models used to describe chemical transport processes in the vadose zone, however, depend on the reaction kinetics--this is particularly true for naturally derived species like U and Sr. However, dissolution rates of sediments are difficult to quantify due to uncertainties associated with both the amount of reactive surface area available in the sediment and the thermodynamic driving forces for the chemical reactions. Mineral dissolution rates measured in the laboratory typically predict rates that are 2 to 4 orders of magnitude faster than estimates based on field measurements. Such experimental rates, which are commonly measured under far-from-equilibrium conditions, are not broadly applicable to many natural systems. Unfortunately, relatively few field measurements of in situ reaction rates are available, and most of those are on silicate soils. Almost no field measurements exist for deep vadose zone materials or for rocks in the saturated zone. The U-series isotope system can be used to quantify reaction rates in aquifers and thick vadose zone environments. The approach is based on alpha -recoil of (super 234) Th atoms across grain boundaries, which enriches the pore fluid in (super 234) U. Dissolution of the solid phase releases mainly (super 238) U to the pore fluid, so that the (super 234) U/ (super 238) U ratio of the pore fluid is a measure of the local ratio of the dissolution U flux to the alpha -recoil flux. U concentrations and isotope measurements ( (super 234) U/ (super 238) U) are combined with a multicomponent reactive transport model with kinetic treatment of reaction rates in order to constrain reaction rates in the vadose zone at the Hanford Site. U measurements for pore waters, bulk solids, exchangeable and selected mineral phases were conducted on an uncontaminated 70 meter vadose zone core within the 200 West area. The pore water (super 234) U/ (super 238) U activity ratios range from 1.04 to 1.20 in the pore fluids and exchangeable fractions, 1.0 in the bulk solids and from 0.94 to 1.0 in the various size fractions. The measured (super 234) U/ (super 238) U ratios for the vadose zone core yield weathering rates of approximately 10 (super -6.4) yr (super -1) , in general agreement with estimates based on other methods.

Here we describe how long-term chemical weathering rates can be measured for actively eroding landscapes using cosmogenic nuclides together with a geochemical mass balance of weathered soil and parent rock. We tested this approach in the Rio Icacos watershed, Puerto Rico, where independent studies have estimated weathering rates over both short and long timescales. Results from the cosmogenic/mass balance method are consistent with three independent sets of weathering rate estimates, thus confirming that this approach yields realistic measurements of long-term weathering rates. This approach can separately quantify weathering rates from saprolite and from overlying soil as components of the total. At Rio Icacos, nearly 50% of Si weathering occurs as rock is converted to saprolite; in contrast, nearly 100% of Al weathering occurs in the soil. Physical erosion rates are measured as part of our mass balance approach, making it particularly useful for studying interrelationships between chemical weathering and physical erosion. Our data show that chemical weathering rates are tightly coupled with physical erosion rates, such that the relationship between climate and chemical weathering rates may be obscured by site-to-site differences in the rate that minerals are supplied to soil by physical erosion of rock. One can normalize for variations in physical erosion rates using the "chemical depletion fraction", which measures the fraction of total denudation that is accounted for by chemical weathering. This measure of chemical weathering intensity increases with increasing average temperature and precipitation in data from climatically diverse granitic sites, including tropical Rio Icacos and six temperate sites in the Sierra Nevada, California. Hence, across a wide range of climate regimes, analysis of chemical depletion fractions appears to effectively account for site-to-site differences in physical erosion rates, which would otherwise obscure climatic effects on chemical weathering rates. Our results show that by quantifying rates of physical erosion and chemical weathering together, our mass balance approach can be used to determine the relative importance of climatic and nonclimatic factors in regulating long-term chemical weathering rates.

Vesuvius AN - 51736747; 2005-025638 AB - The U-Th/He system can potentially be used for dating volcanic rocks with ages as young as a few thousand years and as old as several million years, thus providing a valuable supplement to radiocarbon and K-Ar dating. Garnet phenocrysts from the 79 AD eruption of Mt. Vesuvius were dated to evaluate the accuracy with which the necessary measurements and corrections can be made. The determined age, corrected for diffusive loss of He, alpha ejection, and initial U-series disequilibrium, is 1885+ or -188 yr which compares well with the known age of 1923 yr. U and Th concentrations were measured by isotope dilution on different aliquots than were used for He concentration measurements. Step-wise degassing yielded an Arrhenius relationship for He diffusion in garnet with an activation energy of 91.31+ or -5.76 kJ/mol and ln D (sub 0) /a (super 2) = -2.00+ or -0.56. The uniformity of U and Th concentrations in garnet was checked by ion microprobe analysis. The (super 234) U/ (super 238) U and (super 230) Th/ (super 238) U activity ratios were measured by MC-ICPMS. The results suggest that with proper analysis and corrections, the U-Th/He method can be used to date young volcanic minerals with useful precision and accuracy, and may therefore be valuable for dating volcanic rocks that have low K or are otherwise difficult to date accurately with Ar-Ar or radiocarbon.

Las Vegas lies above a deep sedimentary basin (maximum depth 5-km) formed by extensional tectonics in the Basin and Range Province. The potential for large earthquakes in the region and possible future nuclear tests at the Nevada Test Site (NTS) expose Las Vegas to seismic risk. Seismologists, computer scientists, engineers at Lawrence Livermore National Laboratory (LLNL), the University of Nevada Reno (UNR) and the University of Nevada Las Vegas (UNLV) are evaluating the response of the basin to seismic ground motion and its effect on structures, with particular emphasis on large structures. Recordings in Las Vegas of earthquakes and historical nuclear explosions at the Nevada Test Site (NTS) have provided valuable constraints on ground motion in the basin. Site response results show that ground motions in the basin can be amplified by factors of 20 or more relative to sites on Las Vegas Valley's periphery. Site response is strongly correlated with basin depth. Additional broadband data have been recorded to augment the coverage of earlier network data. Ground motions are being synthesized using an empirical convolution (transfer function) methodology. Geotechnical investigations of specific sites using ReMi and SASW are being performed to understand the relationship between ground motions and shallow seismic structure. In particular the presence of thick deposits of unconsolidated alluvial fill and strengthening effects of carbonate cementation. Seismic refraction studies are refining the basin depth model reported by Langenheim et al. (2001) based on gravity and seismic reflection. Preliminary results provide constraints on the fill velocities and are consistent with depth-to-basement model. All these results are being integrated into a community geophysical model of the region for use in finite-difference wave propagation calculations. Observed and simulated ground motions from scenario nuclear tests and earthquakes are being used to predict the response of structures in Las Vegas.

It is recognized as being seismically active, containing at least eight tectonically active faults capable of producing mid-scale earthquakes within a highly populated region. In the mid 1950's through the early 1990's, Blume & Associates deployed an array of seismometers in Las Vegas Valley to monitor ground-motions created from nuclear testing at the Nevada Test Site. The coverage area was constrained by the city limits during this era. However, with rapid growth of the City of Las Vegas within the last decade, there is a lack of data within the city's recently expanded northeastern region; the area estimated to be the deepest portion of the basin. To address this issue, Lawrence Livermore National Laboratory (LLNL) and the University of Nevada Las Vegas (UNLV) deployed an array of twelve broadband seismometers in the northern region of the valley in September 2002. These stations recorded data continuously through late January 2003. To better model the depth to basement and basin geometry, differential travel time residuals were calculated through the cross-correlation of P-waves from global teleseismic events. The calculated delay times in the northern regions show variations up to 0.5 seconds over distances of 15 km or less. The residual pattern is consistent across the region and is attributed to zones of thicker basin fill. This supports earlier models of the Las Vegas Basin. Additionally, a collection of regional events in close proximity to the Town of Lavic, in southern California, is inline with the broadband array. The regional Rayleigh and Love waves will be used to calculate the inter-station phase velocity along a portion of the ray path and a phase velocity dispersion curve. This analysis will provide insight to the shear velocity structure of the basin. These studies will contribute to improved models of Las Vegas basin by assessing basin shape, volume, and shear velocity structure of the basin fill. Results of this study will be pertinent to assessing and modeling ground-motions in Las Vegas Valley in the event of an earthquake or future nuclear testing at the Nevada Test Site.

Within Holtwood Gorge, model exposure ages increase with elevation above the modern river bed. The lowest terraces, levels 1 and 2, are 0.25 and 3 m above the modern channel. They yield, respectively, mean exposure ages of 14.0+ or -1.3 ky (n = 11) and 19.2+ or -3.1 ky (n = 25). A single sample from the level 3 terrace (8.5 m above the channel) yields an age of 31.6+ or -3.3 ky. A heavily weathered and eroded high point, standing approximately 20 meters above the modern channel yields a lower limiting age of >97.2+ or -10.5 ky. Model ages for samples collected between the level 2 and 3 terraces range from 17.6+ or -1.9 ky and 23.0+ or -2.5 ky. In order to constrain the spatial and temporal pattern of erosion recorded within the gorge and infer the driving force(s), we collected samples at different spatial scales on each of the three prominent terraces levels. Ages for clusters of three samples 10 to 15 meters apart on both the level 1 and 2 terraces are in tight agreement (50 m drop in sea level during the LGM, implicating climate as the driver of incision. Decreasing ages upstream suggest that this terrace is a time-transgressive surface, sequentially abandoned as the river incised toward level 1 by way of knickpoint retreat. Deglaciation outburst flooding down the Susquehanna River, as suggested by Kochel and Parris (2000, GSA-Abstracts with Programs, v. 32, p. A-28) probably lowered the channel bed further via block quarrying of level 1. Such outburst floods are a plausible explanation for the Latest Pleistocene mean model age, the rough surface texture, and lack of an age gradient along the level 1 terrace.

The low-gradient East Range Road piedmont has two major geomorphic surfaces, an incised (up to a few meters) surface proximal to the upland source basins, and a low-relief surface approximately 1 km from the uplands. Activities of (super 10) Be and (super 26) Al decrease exponentially at depth in a 2-meter pit (EP1) dug into the incised surface. A model of the nuclide decrease at depth suggests the upper 2 meters of sediment was deposited approximately 76,000 ka and has been stable (or has had minimal erosion) since. The nuclide-based age of the surface is consistent with the time required to develop a massive Ck/K horizon (stage III) in the bottom meter of sediment. Activities of (super 10) Be and (super 26) Al in a 1.5-meter pit dug into the low-relief surface (EP2) neither increase nor decrease at depth. A model of the nuclide data, when set in the context of soil development--3 buried soil horizons--presents a scenario of three stable surfaces (each lasting between 10,000 and 25,000 years) and each followed by rapid deposition (40 to 250 mm ky (super -1) ). The total time represented in EP2 is between 57,000 to 75,000 years, a range also consistent with the time required to develop the soils present in EP2. Upland basin sediment has the lowest nuclide activity, sediment from the proximal incised piedmont surface has the highest activity, and sediment from the distal low-relief surface has an intermediate nuclide activity. Using a weighted nuclide-mixing model we determined that approximately 75% of sediment in transport down the piedmont erodes from the upland basins while the remaining 25% is eroded from the incised piedmont surface. Nuclide activities of sediment collected from the incised channels and from the low-relief surface increased steadily down the piedmont. Based on the sediment budget and the down piedmont increase in nuclide activity, we modeled average down gradient sediment speeds of 8 to 23 cm y (super -1) .

Complexes that recognize chromatin are defined by several distinct groups of proteins that either directly modify histones or interact with histone-DNA complexes. A protein microarray format was used to analyze the interaction of various DNA repair proteins with chromatin components. We applied proteins, antibodies and DNA to functionalized glass slides and interrogated the slides with our proteins of interest to identify novel protein-protein interactions for proteins involved in DNA double-strand break repair. Here we demonstrate that the DNA repair protein RAD51B, and not its cognate partner RAD51C, interacts with histones and not nucleosomes. Nucleosome-specific interactions were demonstrated with the recently identified SWI/SNF protein, SMARCAL1. Unique RAD51B-histone interactions were corroborated using Far Western analysis. This is the first demonstration of an interaction between RAD51B and histone proteins that may be important for the successful repair of DNA double-strand breaks.

The system is designed to provide early warning to civilians in the event of a terrorist attack. The final APDS will be completely automated, offering aerosol sampling, inline sample preparation fluidics, multiplexed detection and identification immunoassays, and orthogonal, multiplexed PCR (nucleic acid) amplification and detection. The system performance (current capabilities include aerosol collection, multiplexed immunoassays, sample archiving, data reporting, and alarming) was evaluated in a field test conducted in a Biosafety Level 3 facility, where the system was challenged with, and detected, a series of aerosolized releases containing two live, virulent biological threat agents (Bacillus anthracis and Yersinia pestis).

Characteristic mass spectra from individual bacterial endospores of Bacillus subtilis var. niger were obtained in a bipolar aerosol time-of-flight mass spectrometer using a pulsed 266-nm laser for molecular desorption and ionization. Spectra from single spores collected at an average fluence of similar to 0.1 J/cm super(2) frequently contain prominent peaks attributed to arginine, dipicolinic acid, and glutamic acid, but the shot-to-shot (spore-to-spore) variability in the data may make it difficult to consistently distinguish closely related Bacillus species with an automated routine. Fortunately, a study of the laser power dependence of the mass spectra reveals clear trends and a finite number of "spectral types" that span most of the variability. This, we will show, indicates that a significant fraction of the variability must be attributed to fluence variations in the profile of the laser beam.

AN - 73609604; 12950105 AB - De novo aberrations in chromosome structure represent important categories of paternally transmitted genetic damage. Unlike numerical abnormalities, the majority of de novo structural aberrations among human offspring are of paternal origin. We report the development of a three-color fluorescence in situ hybridization (FISH) assay (CT8) to detect mouse sperm carrying structural and numerical chromosomal abnormalities. The CT8 assay uses DNA probes for the centromeric and telomeric regions of chromosome 2, and a probe for the subcentromeric region of chromosome 8. The CT8 assay was used to measure the frequencies of sperm carrying certain structural aberrations involving chromosome 2 (del2ter, dup2ter, del2cen, dup2cen), disomy 2, disomy 8, and sperm diploidy. Analysis of approximately 80,000 sperm from eight B6C3F1 mice revealed an average baseline frequency of 2.5 per 10,000 sperm carrying partial duplications and deletions of chromosome 2. Extrapolated to the entire haploid genome, approximately 0.4% of mouse sperm are estimated to carry structural chromosomal aberrations, which is more than fivefold lower than the spontaneous frequencies of sperm with chromosome structural aberrations in man. We validated the CT8 assay by comparing the frequencies of abnormal segregants in sperm of T(2;14) translocation carriers detected by this assay against those detected by chromosome painting cytogenetic analysis of meiosis II spermatocytes. The CT8 sperm FISH assay is a promising method for detecting structural chromosome aberrations in mouse sperm with widespread applications in genetics, physiology, and genetic toxicology.

AN - 71435134; 14630535 AB - PURPOSETo characterize the cellular functions associated with the altered transcript profiles of mouse brain exposed to low-dose in vivo gamma-irradiation.MATERIALS AND METHODSCerebral RNA was isolated at 30 min and 4 h after whole-body irradiation at 0.1 or 2 Gy, hybridized to random oligonucleotide arrays, and evaluated for time and dose-response patterns by multifactorial analyses.RESULTSBrain irradiation modulated the expression patterns of 1574 genes, of which 855 showed more than 1.5-fold variation. about 30% of genes showed dose-dependent variations, including genes exclusively affected by 0.1 Gy. About 60% of genes showed time-dependent variation with more genes affected at 30 min than at 4 h. Early changes involved signal transduction, ion regulation and synaptic signalling. Later changes involved metabolic functions including myelin and protein synthesis. Low-dose radiation also modulated the expression of genes involved in stress response, cell-cycle control and DNA synthesis/repair.CONCLUSIONSDoses of 0.1 Gy induced changes in gene expression that were qualitatively different from those at 2 Gy. The findings suggest that low-dose irradiation of the brain induces the expression of genes involved in protective and reparative functions, while down-modulating genes involved in neural signalling activity.

Yet whereas numerous magma transport arguments involve hydrous and SiO (sub 2) -rich volcanic products, current clinopyroxene-liquid thermobarometers have been calibrated only from basaltic liquid compositions. To remedy this deficiency, new thermobarometers have been calibrated using new experiments that include hydrated (water-undersaturated) and SiO (sub 2) -rich liquids ranging to 71.3 wt% SiO (sub 2) . As with prior models, the new calibrations are based on jadeite crystallization and jadeite-diopside+hedenbergite exchange equilibria: P(kbar) = -88.3 + 2.82X10 (super -3) T(K)ln {[Jd (super cpx) ] / [Na (super liq) Al (super liq) (Si (super liq) ) (super 2) ]} + 2.19X10 (super -2) T(K)-25.1 ln[Ca (super liq) Si (super liq) ] + 7.03[Mg' (super liq) ] + 12.4 ln[Ca (super liq) ] 10 (super 4) /T(K) = 4.60-4.37X10 (super -1) ln{[Jd (super cpx) Ca (super liq) Fm (super liq) ] / [DiHd (super cpx) Na (super liq) Al (super liq) ]} - 6.54X10 (super -1) ln[Mg' (super liq) ] - 3.26X10 (super -1) ln[Na (super liq) ] - 6.32X10 (super -3) [P(kbar)] - 0.92 ln[Si (super liq) ] + 2.74X10 (super -1) ln[Jd (super cpx) ]. Here, T is in Kelvins and P is in kbar. Jd (super cpx) is the mole fraction of jadeite in clinopyroxene, where pyroxene cations are calculated on the basis of 6 O atoms, and Jd is the lesser of Na or (super VI) Al; remaining Al is used to form CaTs. DiHd (super cpx) is the mole fraction of diopside + hedenbergite in clinopyroxene, calculated as the fraction of Ca remaining after forming CaTs (= (super VI) Al-Jd), CaTiAl (sub 2) O (sub 6) [= ( (super IV) Al-CaTs)/2], and CaCr (sub 2) SiO (sub 6) ? (= Cr/2). Terms such as Al (super liq) refer to the cation fraction of AlO (sub 1.5) in the liquid, Fm (super liq) is the sum FeO (super liq) +MgO (super liq) , and Mg' (super liq) is the cation fraction ratio MgO (super liq) /(MgO (super liq) +FeO (super liq) ). Errors are similar to earlier models that utilize basalt compositions only. For the barometer, R (super 2) = 0.97 and the standard error of estimate (SEE) is 1.7 kbar for the regression data; for the thermometer R (super 2) = 0.96 and the SEE is 33 K. The models are applied to Neogene lavas from the Tibetan Plateau, and Neogene-Quaternary lavas from the eastern Snake River Plain (SRP), Idaho. Crystallization depths for Tibet cluster at the middle/lower crust boundary. Magma-crust density relationships suggest that the middle crust may act as a level of neutral buoyancy. In the SRP, however, magmas appear to bypass several possible density traps. We suggest that fracture properties, such as dike size and aspect ratio, control magma transport in the SRP.

Before this, buffering was primarily accomplished by adjustment of shallow-water carbonate deposition to balance oceanic inputs from weathering on land. Neoproterozoic ice ages of near-global extent and multimillion-year duration and the formation of distinctive sedimentary (cap) carbonates can thus be understood in terms of the greater sensitivity of the Precambrian carbon cycle to the loss of shallow-water environments and CO (sub 2) -climate feedback on ice-sheet growth.

In this paper, we utilize a detailed numerical model of groundwater flow in a region encompassing a large artificial groundwater recharge operation in Orange County, California to evaluate the potential for transport of viruses and protozoan oocysts in such a system, as dictated by a transport model that includes colloid filtration and microbial inactivation components. The purpose of the model is not oriented towards the analysis of any perceived or real microbial contamination, but rather is directed at understanding the influence of aquifer heterogeneity within the modeled system. The transport model is based upon a novel representation of geologic heterogeneity, a high-resolution flow simulator, and an efficient streamline-based transport algorithm. Example virus transport simulations illustrate a large degree of variability in virus breakthrough across water supply pumping wells, with shallower wells providing less than two orders of magnitude of virus removal, and deeper wells indicating many orders of magnitude of virus removal. Simulation results also show variability among pathogens modeled, with Cryptosporidium parvum filtered to a much greater degree than other pathogens. Comparison to transport of an abiotic colloid and a conservative chemical tracer are provided to illustrate the influence of filtration and inactivation on the transport process. The results emphasize the need for improved microbial transport models in realistic aquifer systems, more reliable virus characterization methods and monitoring networks, and their ultimate integration into a broader epidemiological and regulatory framework for aquifer management.

AN - 73651610; 12971803 AB - The understanding of beryllium chemistry in human body fluids is important for understanding the prevention and treatment of chronic beryllium disease. Thermodynamic modeling has traditionally been used to study environmental contaminant migration and rarely in the examination of metal (particularly beryllium) toxicology. In this work, a chemical thermodynamic speciation code (MINTEQA2) has been used to model and understand the chemistry of beryllium in simulated human biological fluids such as intracellular, interstitial, and plasma fluids, a number of airway surface fluids for patients with lung conditions, saliva, sweat, urine, bile, gastric juice, and pancreatic fluid. The results show that predicted beryllium solubility and speciation vary markedly between each simulated biological fluid. Formation of beryllium hydroxide and/or phosphate was observed in most of the modeled fluids, and results support the postulation that beryllium absorption in the gastrointestinal tract may be limited by the formation of beryllium phosphate solids. It is also postulated that beryllium is potentially 13% less soluble in the airway surface fluid of a patient with asthma when compared to a "normal" case. The results of this work, supported by experimental validation, can aid in the understanding of beryllium toxicology. Our results can potentially be applied to assessing the feasibility of biological monitoring or chelation treatment of beryllium body burden.

AN - 71378046; 14632059 AB - A commercially available alpha-particle spectrometer and 210Po alpha-particle source were used to determine the mass of microgram quantities of biomolecules. Samples were deposited in microliter volumes on thin silicon nitride windows and dried. The energy loss of the alpha-particles after traversing the sample was converted to a mass using tabulated alpha-particle stopping powers. The measurement was absolute, independent of biomolecule species, and no standards were needed for quantitation. The method has a dynamic range of 0.1-100 microg for deposits of diameter 1-2 mm. The precision varies from approximately 20% at 100 ng to a few percent at 5-100 microg. The silicon nitride windows allow multimodal analysis of the same quantified sample, including PIXE probing of elemental abundances, molecular identification by mass spectrometry, and isotopic quantitation of interactions. The method was used with accelerator mass spectrometry to quantify specific activities of microgram quantities of 14C-labeled proteins.

These variations occurred with periodicities similar to those of solar activity and appear to be coherent with time series of the cosmogenic nuclides (super 14) C and (super 10) Be as well as North Atlantic drift ice. Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.

Radiocarbon dates from three core sites constrain the timing of late Quaternary paleoenvironmental changes in the Central Andes and highlight the site-specific factors that limit the radiocarbon geochronometer. With the exception of mid-Holocene sediments, all cores are generally devoid of macrophyte fragments, thus bulk organic fractions are used to build core chronologies. Comparisons of radiocarbon results for chemically defined fractions (bulk decalcified, humate, humin) suggest that ages derived from all fractions are generally coherent in the post-13,500 yr BP time interval. In the pre-13,500 yr BP time interval, ages derived from humate extracts are significantly younger (300-7000 years) than ages from paired humin residues. Gross age incoherencies between paired humate and humin sub-fractions in pre-13,500 yr BP sediments from all core sites probably reflect the net downward migration of humates. Ages derived from bulk decalcified fractions at our shallow water (90 m) and deep water (230 m) core sites consistently fall between ages derived from humate and humin sub-fractions in the pre-13,500 yr BP interval, reflecting that the bulk decalcified fraction is predominantly a mixture of humate and humin sub-fractions. Bulk decalcified ages from the pre-13,500 yr BP interval at our intermediate depth core site (150 m) are consistently older than humate (youngest) and humin sub-fractions. This uniform, reproducible pattern can be explained by the mobilization of a relatively older organic sub-fraction during and after the re-acidification step following the alkaline treatment of the bulk sediment. The inferred existence of this "alkali-mobile, acid-soluble" sub-fraction implies a different depositional/post-depositional history that is potentially associated with a difference in source material. While internally consistent geochronologies can be developed for the Lake Titicaca sequence using different organic fractions, mobile organic sub-fractions and fractions containing mobile sub-fractions should generally be avoided in geochronology studies. Consequently, we believe humin and/or bulk decalcified ages provide the most consistent chronologies for the post-13,500 yr BP interval, and humin ages provide the most representative ages for sedimentation prior to 13,500 yr BP interval. Using the age model derived from the deep water core site and a previously published isotope-based lake-level reconstruction, we present a qualitative record of lake level in the context of several ice-core records from the western hemisphere. We find the latest Pleistocene lake-level response to changing insolation began during or just prior to the Bolling/Allerod period. Using the isotope-based lake-level reconstruction, we also find the 85-m drop in lake level that occurred during the mid-Holocene was synchronous with an increase in the variability of ice-core delta (super 18) O from a nearby icecap, but was not reflected in any of the polar ice-core records recovered from the interior of Antarctica and Greenland.

Laboratory measured electrical resistivities of samples of sedimentary rocks known to border the fault to the east are comparable to resistivities of the anomalous zone. We suggest that the anomalous region results from conductive sedimentary rocks in a plunging syncline that is adjacent to the fault, rather than caused by fractured rock. If correct, the current surface trace of the San Andreas fault at Middle Mountain does not form the boundary between the Salinian block and the North American plate. Instead, that boundary is approximately 1 km west and collocated with current seismicity. Abstract Copyright Copyright 2003 by the American Geophysical Union.

AN - 73609835; 12948828 AB - Twenty-five commercial pet foods were analyzed for mutagenic activity using the Ames/Salmonella test with strain TA98 and added metabolic activation. All but one gave a positive mutagenic response. Fourteen of these samples were analyzed for heterocyclic amine mutagens/carcinogens and all but one contained 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and 10 of 14 contained 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) as analyzed by HPLC and confirmed by photodiode array peak matching. From these findings it is hypothesized that there is a connection between dietary heterocyclic amines and cancer in animals consuming these foods.

AN - 73560913; 12902424 AB - UNLABELLEDRadioimmunotherapy for non-Hodgkin's lymphoma often results in surprisingly high response rates compared with those expected from estimated absorbed radiation doses. Several factors, including radiobiologic response, selective targeting, and heterogeneous absorbed radiation within the lymphoma, are likely to contribute to the lack of a dose-response relationship. This article investigates the impact of nodal regression on absorbed radiation dose and applies a correction factor to account for its effect.METHODSThe radioactivity in and regression of 37 superficial lymph nodes were measured in 7 non-Hodgkin's lymphoma patients treated with 775-3,450 MBq/m(2) of (131)I-Lym-1 monoclonal antibody. Nodal dimensions were measured with calipers and radioactivity was quantitated using gamma-camera imaging on multiple days after (131)I-Lym-1 injection. Both nodal regression and radioactivity were fit with monoexponential functions. Formulas were developed to account for simultaneous change in nodal mass and radioactivity. All lymph nodes with size and radioactivity measurements, and exponential-fit coefficients of determination of >0.8, were included in the analysis.RESULTSA 3 orders-of-magnitude node-to-node variation in initial radiopharmaceutical concentration (MBq/g) was observed, with the highest concentrations in the smallest nodes. Reduction in radioactivity as a function of time (biologic half-life) varied by about a factor of 2. In contrast, the rate of nodal regression varied by orders of magnitude, from a 14-h half-time to no regression at all. Five nodes regressed with a half-time that was shorter than their observed effective radiopharmaceutical half-life. Accounting for the effect of nodal regression resulted in dose corrections ranging from 1 (no correction) to a factor of >10, with 70% of nodes requiring a correction factor of at least 20% and >50% of nodes requiring a correction factor of >2. Corrected for nodal regression, 46% of nodes analyzed had absorbed radiation doses of >10 Gy and 32% had doses of >20 Gy.CONCLUSIONThese results highlight the importance of accounting for change in mass, particularly tumor regression, when assessing absorbed radiation dose for tissues whose mass changes during the time the radiation dose is being absorbed.

AN - 73323885; 12757787 AB - The addition of oxygen-bearing compounds to diesel fuel considerably reduces particulate emissions. TGME and DBM have been identified as possible diesel additives based on their physicochemical characteristics and performance in engine tests. Although these compounds will reduce particulate emissions, their potential environmental impacts are unknown. As a means of characterizing their persistence in environmental media such as soil and groundwater, we conducted a series of biodegradation tests of DBM and TGME. Benzene and methyl tertiary butyl ether (MTBE) were also tested as reference compounds. Primary degradation of DBM fully occurred within 3 days, while TGME presented a lag phase of approximately 8 days and was not completely degraded by day 28. Benzene primary degradation occurred completely by day 3 and MTBE did not degrade at all. The total mineralized fractions of DBM and TGME achieved constant values as a function of time of approximately 65% and approximately 40%, respectively. Transport predictions show that, released to the environment, DBM and TGME would concentrate mostly in soils and waters with minimal impact to air. From an environmental standpoint, these results combined with the transport predictions indicate that DBM is a better choice than TGME as a diesel additive.

Using geomorphology and (super 10) Be cosmogenic radionuclide dating, a succession of moraines from three glaciated valleys is dated to 18-20 ka (Last Glacial Maximum), 15-16 ka (Heinrich Event 1), 12-13 ka (Younger Dryas Stade), and 5-9 ka (early-middle Holocene). These ages substantiate the view that glaciation throughout the American Cordilleras was synchronous during the late Quaternary. Furthermore, these data show that glacial advances in southern California occur when a significant decrease in summer temperature is coupled with an increase in moisture flux producing high winter snowfall. This allows for perennial snow accumulation that may, under appropriate conditions, persist to form glacial ice.

Comparable increases are evident in climate model experiments. The latter show that human-induced changes in ozone and well-mixed greenhouse gases account for similar to 80% of the simulated rise in tropopause height over 1979-1999. Their primary contributions are through cooling of the stratosphere (caused by ozone) and warming of the troposphere (caused by well-mixed greenhouse gases). A model-predicted fingerprint of tropopause height changes is statistically detectable in two different observational ("reanalysis") data sets. This positive detection result allows us to attribute overall tropopause height changes to a combination of anthropogenic and natural external forcings, with the anthropogenic component predominating.

AN - 73500335; 12875410 AB - Electro-osmosis, a coupled-flow phenomenon in which an applied electrical potential gradient drives water flow, may be used to induce water flow through fine-grained sediments. Test cell measurements of electro-osmotic transport in clayey cores extracted from the 27-31 m depth range of the Lawrence Livermore National Laboratory site indicate the importance of pH control within the anode and cathode reservoirs. In our first experiment, pH was not controlled. As a result, carbonate precipitation and metals precipitation occurred near the cathode end of the core, with acidification near the anode. The combination of these acid and base reactions led to the decline of electro-osmotic flow by a factor of 2 in less than one pore volume. In a second experiment, long-term water transport (>21 pore volumes) at stable electro-osmotic conductivity (k(eo) approximately 1 x 10(-9) m2/s-V) was effected with anode reservoir pH > 8, and cathode reservoir pH < 6. Hydraulic conductivity (k(h)) of the same core was 4 x 10(-10) m/s under a 0.07 MPa hydraulic gradient without electro-osmosis. Stable electro-osmotic flow was measured at a velocity of 4 x 10(-7) m/s under a 4 V/cm voltage gradient, and no hydraulic gradient-3 orders of magnitude greater than the hydraulic flow. We also observed chloroform production in the anode reservoir, resulting from electrochemical production of chlorine gas reacting with trace organics.

Our analysis is based on a multicentury present-day climate simulation performed with an ENSO-resolving Coupled General Circulation Model (CGCM). In consistency with observations, it is found that ENSO variance undergoes changes with a time scale of about 10-20 years. This decadal beat is closely linked to the second dominant pattern of tropical (sub)surface temperature variability. The dipole-like characteristic of this mode is generated mainly by the interplay of horizontal, vertical advection and mixing. We suggest a nonlinear mechanism, which is capable of generating decadal tropical climate anomalies as well as decadal ENSO amplitude modulations (DEAMs) without invoking extratropical dynamics. This mechanism is based on the idea of homoclinic orbits. This new paradigm is validated using a low-dimensional ENSO model that is derived empirically from the CGCM simulation.

These include the degree to which a gene can be silenced, the length of time for which the gene remains silenced, the degree of recovery of gene function, and the effects of the silencing process on general cell functions. We hypothesized that changing the nucleic acid composition of the siRNA constructs used for silencing would affect these parameters. With siRNA gene silencing of the glucose-6-phosphate dehydrogenase gene as a baseline, we found that siDNA molecules have an effect that is similar in duration but lesser in degree, whereas hybrid DNA:RNA molecules have an effect that is enormously greater in both duration and degree.

Cosmogenic radionuclide (CRN) surface exposure dating of moraine boulders defines the timing of each glacial advance and refines the previous glacial chronologies. The CRN data show that glaciation was most extensive during the early part of the last glacial (marine oxygen isotype stage [MIS] 3 and earlier), but limited during MIS 2 (the global Last Glacial Maximum) and the Holocene. A previously assumed Neoglacial advance is dated to 3.6+ or -0.3 ka and the CRN dates confirm a glacial advance ca. 1 ka. These results show that glaciations on the south side of Everest were not synchronous with the advance of Northern Hemisphere ice sheets, yet glaciations within the Himalaya, the world's highest mountain belt, were synchronous during the late Quaternary. The existence of glacial advances during times of increased insolation suggests that enhanced moisture delivered by an active south Asian summer monsoon is largely responsible for glacial advances in this part of the Himalaya. These data allow us to quantify the importance of global climate change and monsoon influence on glaciation in the Himalaya.

The baseline experiment was a long integration of a state-of-the-art-coupled atmosphere-ocean-land general circulation model (GCM). A sensitivity experiment was conducted in which the ocean and atmosphere were fully interactive but the soil moisture was specified. This paper describes a connection found between land-atmosphere coupling and midlatitude sea surface temperature (SST) variability in the North American-North Atlantic sector. Specifying soil moisture results in a reduction in surface and atmospheric temperature variability and also an increase in net heat flux variability. Surface temperature variance is reduced because it is constrained by the fixed soil moistures. Since the surface temperature cannot equilibrate with a given atmospheric anomaly, the resulting heat flux will be quite large and will act to damp the atmospheric anomaly. This is consistent with larger heat flux variance and reduced temperature variance in the simulation with suppressed land processes. SST anomalies in the midlatitude Atlantic are sensitive to air temperature and moisture anomalies modified over the North American continent, so it is not unexpected that SST variance is significantly reduced when land temperature variability decreases. Oceanic "re-emergence" operates in both simulations but is weaker in the fixed soil moisture integration, particularly in a region of the western North Atlantic contiguous with North America. Reemergence is the mechanism by which late winter ocean temperature anomalies are sequestered below the stable summer ocean mixed layer and reentrained into the deepening autumn mixed layer. The larger oceanic anomalies in the fully coupled simulation decay more slowly and are a partial explanation for stronger reemergence. However, during the second winter, the atmospheric forcing favors the same sign of SST anomalies as those reemerging and, therefore, acts to reinforce the anomalies in the fully coupled simulation. An area averaged SST index was constructed for the region of the western North Atlantic where reemergence was most notably reduced. This index was used to construct composites which suggest that, in the fully coupled model, land surface temperature and SST anomalies both reemerge the second winter, whereas in the suppressed land processes simulation, there is no winter-to-winter reappearance of land surface temperature anomalies.

Among other uses, such models are employed both to detect anthropogenic effects in the climate record of the past century and to project future climatic changes due to human production of greenhouse gases and aerosols. CMIP has archived output from both constant forcing ("control run") and perturbed (1% per year increasing atmospheric carbon dioxide) simulations. This report summarizes results form 18 CMIP models. A third of the models refrain from employing ad hoc flux adjustments at the ocean-atmosphere interface. The new generation of non-flux-adjusted control runs are nearly as stable as--and agree with observations nearly as well as--the flux-adjusted models. Both flux-adjusted and non-flux-adjusted models simulate an overall level of natural internal climate variability that is within the bounds set by observations. These developments represent significant progress in the state of the art of climate modeling since the Second (1995) Scientific Assessment Report of the Intergovernmental Panel on Climate Change (IPCC; see Gates et al. [Gates, W. L., et al., 1996. Climate models--Evaluation. Climate Climate 1995: The Science of Climate Change, Houghton, J. T., et al. (Eds.), Cambridge Univ. Press, pp. 229-284]). In the increasing-CO (sub 2) runs, differences between different models, while substantial, are not as great as one might expect from earlier assessments that relied on equilibrium climate sensitivity.

To evaluate internal climate variability, we apply spectral analysis to time series of surface air temperature (SAT) from nine coupled general circulation model (GCM) simulations, three recent global paleotemperature reconstructions, and Northern Hemisphere (NH) instrumental records. Our comparison is focused on the NH due to the greater spatial and temporal coverage and validation of the available NH temperature reconstructions. The paleotemperature reconstructions capture the general magnitude of NH climate variability, but not the precise variance and specific spatial, temporal, or periodic signals demonstrated in the instrumental record. The models achieved varying degrees of success for each measure of variability analyzed, with none of the models consistently capturing the appropriate variability. In general, the models performed best in the analysis of combined mean annual land and marine variability.

This is potentially important for the global climate since the release of latent heat due to condensation of water vapour and fallout of rain from cumulus convection is the most important source for available potential energy in the free troposphere. Beyond this, cumulus convection is a key process in controlling the water vapour content of the atmosphere. The sensitivity of the global climate to modification in rain efficiency of convective clouds due to the suppression of drop coalescence by anthropogenic aerosols is studied by using the atmospheric general circulation model (A-GCM), ECHAM4. This paper presents results from a 15-year sensitivity study, which considers the aerosol effect on warm precipitation formation. Effects on ice processes are not included yet, and therefore the results likely underestimate the magnitude of the full effects due to suppression of precipitation. Instantaneous forcing is large locally (up to 100% reduction of precipitation and the related latent heat release) but confined to small areas, leading to small large-scale mean anomalies in the convective heating and therefore the vertical temperature gradient. We found a definite perturbation of the global circulation, showing distinct sensitivity to the impact of aerosols on suppressing rainfall.

The gravity wave retardation (GWR) method is a simple technique that slows down surface waves and allows a simple explicit integration to be used. Here the method is discussed and applied to a layer model of the tropical Indian Ocean subject to monthly climatological wind forcing. The errors introduced by the GWR method on the barotropic ocean circulation and sea surface elevation are analyzed. Comparison to a model integration with a flat bottom demonstrates that GWR integrations with a speed-up factor up to 16 indeed capture some influence of the bottom relief, in the sense that the GWR solutions have less error than if topography was ignored. Integrations with a speed-up factor of up to 8 are found to model the barotropic circulation well, implying that the GWR method can be applied to climate modelling.

Based on radioactive decay along a water flow path the (super 81) Kr/Kr ratios are directly converted to groundwater residence times. Results are in a range of 225-400 kyr with error bars in the order of 15% primarily due to counting statistics in the cyclotron accelerator mass spectrometer measurement. Additional uncertainties from subsurface production and/or exchange with stagnant porewaters in the confining shales appear to be of the same order of magnitude. These (super 81) Kr ages are then used to calibrate the (super 36) Cl and the (super 4) He dating methods. Based on elemental analyses of rock samples from the sandstone aquifer as well as from the confining Bulldog shale the in situ flux of thermal neutrons and the corresponding (super 3) He/ (super 4) He and (super 36) Cl/Cl ratios are calculated. From a comparison of: (i) the (super 3) He/ (super 4) He ratios measured in the groundwater samples with the calculated in situ ratios in rocks and (ii) the measured delta (super 37) Cl ratios with the (super 4) He concentrations measured in groundwater it is concluded that both helium and chloride are most likely added to the aquifer from sources in the stagnant porewaters of the confining shale by diffusion and/or mixing. Based on this "working hypothesis" the (super 36) Cl transport equation in groundwater is solved taking into account: (i) radioactive decay, (ii) subsurface production in the sandstone aquifer (with an in situ (super 36) Cl/Cl ratio of 6X10 (super -15) ) and (iii) addition of chloride from a source in the confining shale (with a (super 36) Cl/Cl ratio of 13X10 (super -15) ). Lacking better information it is assumed that the chloride concentration increased linearly with time from an (unknown) initial value C (sub i) to its measured present value C = C (sub i) +C (sub a) , where C (sub a) represents the (unknown) amount of chloride added from subsurface sources. Using the (super 81) Kr ages of the four groundwater samples and a reasonable initial (super 36) Cl/Cl ratio of 125X10 (super -15) , which is consistent with other studies in this part of the GAB, it is then possible to determine (C (sub i) ,C (sub a) ) parameter sets for all four samples and consequently to simulate the Cl and the (super 36) Cl evolution with time. Strong evidence that the whole procedure is adequate comes from: (i) a comparison of C (sub i) with the calculated noble gas recharge temperatures (NGRT) indicating that a higher NGRT is related to higher input chloride concentrations C (sub i) (because of higher evapotranspiration) and (ii) a comparison of C (sub a) with the measured (super 4) He concentration confirming the idea that both chloride and helium are added to the groundwater in parallel. It turns out that the four samples fall into two groups: (i) for two of the samples (Raspberry Creek and Oodnadatta) initial (super 36) Cl concentrations are high and (super 36) Cl dating based on radioactive decay is possible. The (super 4) He accumulation rate for these two samples is low (0.2X10 (super -10) cm (super 3) STP (super 4) He/(cm (super 3) water yr)); (ii) for the other two samples (Duck Hole and Watson Creek) the initial (super 36) Cl concentration is low and therefore subsurface processes dominate resulting in almost constant (super 36) Cl concentrations with time; (super 36) Cl groundwater dating is not possible.

The same computer codes were used to construct the atmosphere, ocean, sea ice and land surface components of the two models, and they employ the same types of sub-grid-scale parameterization schemes. The two model versions differ primarily, but not solely, in their spatial resolution. Comparisons are made of results from six coarse-resolution R15 climate change experiments and three medium-resolution R30 experiments in which levels of greenhouse gases (GHGs) and sulfate aerosols are specified to change over time. The two model versions yield similar global mean surface air temperature responses until the second half of the 21st century, after which the R15 model exhibits a somewhat larger response. Polar amplification of the Northern Hemisphere's warming signal is more pronounced in the R15 model, in part due to the R15's cooler control climate, which allows for larger snow and ice albedo positive feedbacks. Both models project a substantial weakening of the North Atlantic overturning circulation and a large reduction in the volume of Arctic sea ice to occur in the 21st century. Relative to their respective control integrations, there is a greater reduction of Arctic sea ice in the R15 experiments than in the R30 simulations as the climate system warms. The globally averaged annual mean precipitation rate is simulated to increase over time, with both model versions projecting an increase of about 8% to occur by the decade of the 2080s. While the global mean precipitation response is quite similar in the two models, regional differences exist, with the R30 model displaying larger increases in equatorial regions.

Though the spatial and temporal pattern of radiative forcing from greenhouse gases differs from that of sunlight, it was shown in a recent study that these schemes would largely mitigate regional or seasonal climate change for a doubling of the atmospheric CO (sub 2) content. Here, we examine the ability of reduced solar luminosity to cancel the effects of quadrupling of CO (sub 2) content. In agreement with our previous study, geoengineering schemes could markedly diminish regional and seasonal climate change. However, there are some residual climate changes: in the geoengineered 4XCO (sub 2) climate, a significant decrease in surface temperature and net water flux occurs in the tropics; warming in the high latitudes is not completely compensated; the cooling effect of greenhouse gases in the stratosphere persists and sea ice is not fully restored. However, these residual climate changes are much smaller than the change from quadrupling of CO (sub 2) without reducing solar input. Caution should be exercised in interpretation because these results are from a single model with a number of simplifying assumptions. There are also many technical, environmental and political reasons not to implement geoengineering schemes.

The composite materials were found to be superior in removing uranium from a stock solution compared to GAC alone evaluated by a modified ASTM D 3860-98 method for batch testing. The testing results were evaluated using a Freundlich adsorption model. The best performing material has parameters of n = 2.87 and K sub(f) = 1169 compared to n = 1.00, and K sub(f) = 20 for GAC alone. The composite materials were formed by mixing (CH sub(3)O) sub(4)Si with the hydrophobic sol-gel precursor, (CH sub(3)O) sub(3)-SiCH sub(2)CH sub(2)CF sub(3) and with specified modifiers, such as H sub(3)-PO sub(4), Ca(NO sub(3)) sub(2), and (C sub(2)H sub(5)O) sub(3)SiCH sub(2)CH sub(2)P(O)(OC sub(2)H sub(5)) sub(2), gelation catalysts, and GAC in a supercritical reactor system. After gelation, supercritical extraction, and sieving, the composites were tested. Characterization by FTIR and super(31)P NMR indicate the formation of phosphate in the case of the H sub(3)PO sub(4) and Ca(NO sub(3)) sub(2) composites and phosphonic acid related compounds in the phosphonate composite. These composite materials have potential application in the clean up of groundwater at DOE and other facilities.

AN - 85370694; pmid-12765392 AB - The theory of time-reversal super-resolution imaging of point targets embedded in a reciprocal background medium [A. J. Devaney, "Super-resolution imaging using time-reversal and MUSIC," J. Acoust. Soc. Am. (to be published)] is generalized to the case where the transmitter and receiver sensor arrays need not be coincident and for cases where the background medium can be nonreciprocal. The new theory developed herein is based on the singular value decomposition of the generalized multistatic data matrix of the sensor system rather than the standard eigenvector/eigenvalue decomposition of the time-reversal matrix as was employed in the above-mentioned work and other treatments of time-reversal imaging [Prada, Thomas, and Fink, "The iterative time reversal process: Analysis of the convergence," J. Acoust. Soc. Am. 97, 62 (1995); Prada et al., "Decomposition of the time reversal operator: Detection and selective focusing on two scatterers," J. Acoust. Soc. Am. 99, 2067 (1996)]. A generalized multiple signal classification (MUSIC) algorithm is derived that allows super-resolution imaging of both well-resolved and non-well-resolved point targets from arbitrary sensor array geometries. MUSIC exploits the orthogonal nature of the scatterer and noise subspaces defined by the singular vectors of the multistatic data matrix to form scatterer images. The time-reversal/MUSIC algorithm is tested and validated in two computer simulations of offset vertical seismic profiling where the sensor sources are aligned along the earth's surface and the receiver array is aligned along a subsurface borehole. All results demonstrate the high contrast, high resolution imaging capabilities of this new algorithm combination when compared with "classical" backpropagation or field focusing. Above and beyond the application of seismo-acoustic imaging, the time-reversal super-resolution theory has applications in ocean acoustics for target location, and ultrasonic nondestructive evaluation of parts.

AN - 73269344; 12745215 AB - An experimental approach is described for determining protein-small molecule non-covalent ligand binding sites and protein conformational changes induced by ligand binding. The methodology utilizes time resolved limited proteolysis and the high throughput analysis capability of MALDI TOF MS to determine the binding site in a tetanus toxin C-fragment (51 kDa)-doxorubicin (543 Da) non-covalent complex. Comparing relative ion abundances of peptides released from the time resolved limited proteolysis of tetanus toxin C-fragment (TetC) and the TetC-doxorubicin complex every 10 min from 10 to 120 min of digestion revealed that the binding of doxorubicin induced a significant change in surface topology of TetC. Four of the twenty-nine peptides observed by MALDI MS, including amino acids 351-360, 299-304, 305-311 and 312-316, had a lower abundance in the TetC-doxorubicin complex relative to TetC from 10 to 100 min of digestion. A decrease in ion abundance suggests doxorubicin obstructs the access of the protease to one or both termini of these peptides, identifying doxorubicin binding site(s). Conversely, five peptide ions, including amino acids 335-350, 364-375, 364-376, 281-298, and 316-328, all had a greater abundance in the digest of the complex, indicating an increase in accessibility to these sites. These five peptides flank regions of decreased ion abundance, suggesting that doxorubicin not only binds to the surface, but also induces a conformational change in TetC.

In northern Peru (6 degrees S), a stable magnetic component from six Permo-Triassic sites passes fold and reversal tests. The overall mean pole agrees well with Late Permian to Triassic poles from cratonal South America, suggesting this part of Peru has experienced neither significant rotation nor latitudinal transport since the Permo-Triassic. In southern Peru (13 to 16 degrees S), thermal demagnetization isolates stable magnetic components in 16 of 22 Upper Permian to Lower Jurassic sites collected along the transition between the Altiplano and the Eastern Cordillera. These 16 sites are rotated 14 to 147 degrees counterclockwise and pass an inclinations-only fold test. Within the same structural zone, three other Permo-Triassic sites as well as 10 Paleocene sites also show important counterclockwise rotations [Roperch and Carlier, J. Geophys. Res. 97 (1992) 17233-17249; Butler et al., Geology 23 (1995) 799-802]. The large magnitude and exclusively counterclockwise sense of rotation suggest that the tectonic regime included an important sinistral shear component. No correlation exists between rotation amount and rock age, suggesting the rotations are post-Paleocene in age. Because the rotations occur along the fringe of the Eastern Cordillera, they were likely produced during its structural formation, hence from the Late Oligocene to Present. Sinistral shear acting in the northern part of the Bolivian Orocline appears much more pronounced than that north of the Abancay Deflection, which likely arises from differences in convergence obliquity.

The faulting is simulated as a stochastic process with the spatial variation of the key parameters determined by probability distribution functions. The wave propagation from source to site is accounted for by using small earthquake recordings as empirical Green's functions (EGF). This accounts for the regional effects of scattering, attenuation and structure while providing the basis for a broadband (0.5-10 Hz) time history. Because we are interested in sites where the ground motion is expected to be severe, we have included nonlinear wave propagation through the soil. The material properties of the soil column have been determined from laboratory tests, borehole logs and confirmed through seismological modeling of weak motion. We have computed 240 three-component acceleration time histories to represent the range of ground motion one might expect from a M 6.8 earthquake for a site that is located 10 km above the hanging wall of blind thrust (7.1 km closest distance). Based on the suite of time histories we computed a S.D. of 0.45 (natural log units) for the acceleration response spectra in the passband 0.5-10 Hz. The total S.D. (modeling plus parameterization) is 0.6 in natural log units. The mean acceleration response spectrum is near the median 10% in 50-year probabilistic seismic hazard analysis (PSHA) spectrum for the site; the 84% spectrum of the simulations is closer to the 5% in 50 years median spectrum.

The chert clasts were derived from the Senonian Mishash Formation, a chert-bearing chalk, which is widely exposed in the Nahal Zin drainage basin, the drainage system that supplied most of the material to the beach ridges. Simple exposure ages, assuming only exposure at the beach ridge sampling sites, range from 35 to 354 ky; using the ratio (super 26) Al/ (super 10) Be, total clast histories range from 0.46 to 4.3 My, unrelated to the clasts' current position and exposure period on the late Pleistocene beach ridges, 160-177 m below sea level. Optically stimulated luminescence dating of fine sediments from the same and nearby beach ridges yielded ages of 20.0+ or -1.4 ka and 36.1+ or -3.3 ka. These ages are supported by the degree of soil development on the beach ridges and correspond well with previously determined ages of Lake Lisan, which suggest that the lake reached its highest stand around 27 000 cal. years BP. If the clasts were exposed only once and than buried beyond the range of significant cosmogenic nuclide production, then the minimum initial exposure and the total burial times before delivery to the beach ridge are in the ranges 50-1300 ky and 390-3130 ky respectively. Alternatively, the initial cosmogenic dosing could have occurred during steady erosion of the source bedrock. Back calculating such rates of rock erosion suggests values between 0.4 and 12 m My (super -1) . The relatively long burial periods indicate extended sediment storage as colluvium on slopes and/or as alluvial deposits in river terraces. Some clasts may have been stored for long periods in abandoned Pliocene and early Pleistocene routes of Nahal Zin to the Mediterranean before being transported again back into the Nahal Zin drainage system and washed on to the shores of Lake Lisan during the late Pleistocene.

Three systems were examined: (1) a column packed with homogenized aquifer material, (2) undisturbed aquifer cores, and (3) a section of a semi-confined alluvial aquifer encompassing approximately 2000 m (super 2) . Tracer experiments were conducted using non-reactive tracers with different aqueous diffusion coefficients, based on the assumption that the impact of diffusion-mediated mass-transfer processes on solute transport will be dependent upon the magnitude of the diffusion coefficient. For the homogenized packed column, the breakthrough curves for the different tracers were very similar, and the attendant dispersivities were identical. These results indicate, as would be expected, that physical-heterogeneity related diffusive mass transfer did not measurably contribute to solute transport in the homogeneously packed column. Conversely, the results obtained for the undisturbed aquifer cores indicate that diffusive mass transfer, possibly associated with diffusion between zones of lower and higher advection, contributed to solute transport in this system. For the field test, the magnitudes of the dispersivity coefficients were different for the different tracers. Thus, solute transport at the field scale appeared to be influenced by diffusive mass transfer, most likely associated with mass transfer between regions of lower and higher permeability. These results illustrate that tracer tests using tracers with different diffusivities can be used to help elucidate the relative contribution of diffusion-mediated mass transfer to solute transport.

The microbial growth results from the introduction of water, ground support, and waste package materials into the deep unsaturated rock. The simulations, which spanned 1 million years, were accomplished using a newly developed computer code, Microbial Impacts to the Near-Field Environment Geochemistry (MING). MING uses environmental thresholds for limiting microbial growth to temperatures below 120 degrees C and above relative humidities of 90% in repository drifts. Once these thresholds are met, MING expands upon a mass balance and thermodynamic approach proposed by McKinley et al. [FEMS Microbiol. Rev. 20 (1997) 545] by using kinetic rates to supply constituents from design materials and constituent fluxes including solubilized rock components into the drift to perform two separate mass balance calculations as a function of time. The first (nutrient limit) assesses the available nutrients (C, N, P and S) and calculates how many microorganisms can be produced based on a microorganism stoichiometry of C (sub 160) (H (sub 280) O (sub 80) )N (sub 30) P (sub 2) S. The second (energy limit) calculates the energy available from optimally combined redox couples for the temperature and pH at that time. This optimization maximizes those reactions that produce >15 kJ/mol (limit on useable energy) using an iterative linear optimization technique. The final available energy value is converted to microbial mass at a rate of 1 kg of biomass (dry weight) for every 64 MJ of energy. These two values (nutrient limit and energy limit) are then compared and the smaller value represents the number of microorganisms that can be produced over a specified time. MING can also be adapted to investigate other problems of interest as the model can be used in saturated and unsaturated environments and in laboratory situations to establish microbial growth limitations. Other projected uses include investigations of contaminated locations where monitored natural attenuation or engineered bioremediation could be employed.

Most laser safety courses "in-house commercial" discuss laser accidents, causes, and types of injury. Many do not address appropriate actions to be taken if such an accident occurs. This article reviews a sampling of laser accidents that have occurred and provides a quick overview of the appropriate steps to take when a laser accident occurs.

AN - 73203367; 12694741 AB - The pesticide phosphine (PH(3)) is a suspected carcinogen and a known clastogen which has been shown to produce chromosome damage in agricultural workers. To confirm and extend these results we evaluated 22 phosphine appliers and 26 controls matched for age and smoking status. Two independent methods were used to evaluate exposure: fluorescence in situ hybridization (FISH) with whole-chromosome paints of chromosomes 1, 2, and 4 labeled in a single color to quantify translocations in peripheral lymphocytes, and the glycophorin A (GPA) assay to quantify phenotypically mutant (NĂ˜ or NN) erythrocytes. No differences in the frequency of translocations were found in the phosphine appliers compared to the controls, and no effect of cigarette smoking was observed. However, a significant increase in the frequency of translocations with age (P<0.0001) was seen. No effect of phosphine exposure or cigarette smoking was observed in the GPA assay. These results are in contrast to previous findings from this same population which showed an increase in chromosome aberrations among phosphine appliers. The results are most easily interpreted as supporting the effectiveness of the personal protective equipment that is now worn by the workers but which was not employed prior to and during the earlier studies.

In both blind and standard laboratory trials, we demonstrate the simultaneous detection of four simulant agents from a single sample. The challenge agents comprise broad classes of pathogens (virus, protein toxins, bacterial spores, vegetative cells). Assay performance of each analyte was optimized, and dose-response curves and the limits of detection (LODs) for individual analytes are presented. Assay performance, including dynamic range, sensitivity, and LODs for liquid arrays and enzyme-linked immunosorbant assay were compared and are shown to be similar. Maximum assay sensitivity is obtained in similar to 1 h, and good sensitivity is achieved in as little as 30 min. Although the sample matrixes are very complex, even for highly multiplexed assays the samples do not exhibit evidence of nonspecific binding, demonstrating that the assays also have high specificity.
