TY - JOUR T1 - Detective quantum efficiency dependence on x-ray energy weighting in mammography. AN - 85265985; pmid-10619253 AB - An evaluation of the dependence of detective quantum efficiency (DQE) on the incident energy spectrum has been made for mammography. The DQE dependence on the energy spectrum has been evaluated for energy-integrating detectors, photon-counting detectors, and detectors that measure the energy of each photon. To isolate the effect of the x-ray energy spectrum the detector has been assumed to be ideal, i.e., all noise sources are assumed to be zero except for quantum fluctuations. The result shows that the improvement in DQE, if the energy-integrating detector is compared to a single-photon counting detector, is of the order of 10%. Comparing the energy-integrating detector and the detector measuring the energy for each photon the improvement is around 30% using a molybdenum anode spectrum typical in mammography. It is shown that the optimal weight factors to combine the data in the case the energy is measured are very well approximated if the weight factors are proportional to E(-3). Another conclusion is that in calculating the DQE, a detector should be compared to one that uses ideal energy weighting for each photon since this provides the best signal-to-noise ratio. This has generally been neglected in the literature.

AN - 69423533; 10649861 AB - In laboratory experiments, we investigated two task/ambient conditioning systems with air supplied from desk-mounted air outlets to efficiently ventilate the breathing zone of heated manikins seated at desks. In most experiments, the task conditioning systems provided outside air while a conventional ventilation system provided additional space cooling but no outside air. Air change effectiveness (i.e., exhaust air age divided by age of air at the manikin's face) was measured with a tracer gas step-up procedure. Other tracer gases simulated the release of pollutants from nearby occupants and from the floor covering, and the associated pollutant removal efficiencies (i.e., exhaust air concentrations divided by concentrations at manikin's face) were calculated. High values of air change effectiveness (approximately 1.3 to 1.9) and high values of pollutant removal efficiency (approximately 1.2 to 1.6) were measured when these task conditioning systems supplied 100% outdoor air at a flow rate of 7 to 9 L s-1 per occupant. Air change effectiveness was reasonably well correlated with the pollutant removal efficiency. Overall, the experimental data suggest that these task/ambient conditioning systems can be used to improve ventilation and air quality or to save energy while maintaining a typical level of IAQ at the breathing zone.

However, integration of dynamic data typically requires the solution of an inverse problem that can be computationally intensive and becomes practically infeasible for fine-scale reservoir models. A critical issue here is computation of sensitivity coefficients, the derivatives of dynamic production history with respect to model parameters such as permeability and porosity. We propose a new analytic technique that has several advantages over existing approaches. First, the method utilizes an extremely efficient three-dimensional multiphase streamline simulator as a forward model. Second, the parameter sensitivities are formulated in terms of one-dimensional integrals of analytic functions along the streamlines. Thus, the computation of sensitivities for all model parameters requires only a single simulation run to construct the velocity field and generate the streamlines. The integration of dynamic data is then performed using a two-step iterative inversion that involves (i) "lining up" the breakthrough times at the producing well and then (ii) matching the production history. Our approach follows from an analogy between streamlines and ray tracing in seismology. The inverse method is analogous to seismic waveform inversion and thus, allows us to utilize efficient methods from geophysical imaging. We have applied the proposed approach to a highly heterogeneous carbonate reservoir in west Texas. The reservoir model consists of 50,000 cells and includes multiple patterns with 42 wells. Water-cut histories from 27 producing wells are utilized to characterize porosity and permeability distribution in the reservoir, a total of 100,000 parameters.

Basin-scale hydrologic processes and other local climate impacts related to water resources such as reservoir management, crop and forest productivity, and ecosystem response require climate information at scales that are much finer than current and future GCM resolutions. The Regional Climate System Model (RCSM) is a dynamic downscaling system that has been used since 1994 for short-term precipitation and streamflow predictions and seasonal hindcast analysis with good skill. During the 1997-1998 winter, experimental seasonal forecasts were made in collaboration with the NOAA Climate Prediction Center and UCLA with promising results. Preliminary studies of a control and 2xCO sub(2) perturbation for the southwestern U.S. have been performed.

CH sub(4) concentrations in soil gas samples from areas with high residual refinery waste concentrations were found to fluctuate greatly in response to seasonal changes in groundwater levels. The super(14)C content of the CH sub(4) was low (0.03-0.10 times modern), indicating that it was predominantly formed from the refinery wastes. The delta super(13)C and delta D values of the CH sub(4) were consistent with formation via acetate fermentation. The source of the acetate to drive this reaction is not clear but could be due to either aerobic degradation of the hydrocarbons caused by influx of oxygen-enriched rainwater or anaerobic hydrocarbon degradation. In the vadose zone, the delta super(13)C and delta D values of the CH sub(4) increased as its concentration decreased, indicating that the CH sub(4) was being oxidized by methanotrophic bacteria. This is confirmed by large decreases in the delta super(13)C values and super(14)C content of coexisting CO sub(2). The results of this study show that soil microorganisms can utilize highly weathered hydrocarbons to produce significant concentrations of CH sub(4). They also demonstrate how easily misleading conclusions about levels of intrinsic bioremediation can be drawn from spatially or temporally limited sample sets.

AN - 69412864; 10638840 AB - The LBNL/QGI occupational carbon monoxide (CO) dosimeter (LOCD), a new, inexpensive CO passive sampler, was field-validated in an occupational exposure assessment study in the Moscone Convention Center (MCC) in San Francisco, CA in January, 1997. The LOCD measures time-weighed-average (TWA) CO exposures from 10 to 800 parts per million hours (ppm h; accuracy +/- 20%; precision 10 ppm h). This device represents a major improvement over currently available low-cost personal CO monitors. At the MCC, over 1000 workers set up and remove exhibitions. Forty propane-powered forklifts moved materials throughout the 42,000 m2 of exhibit halls. Diesel truck emissions enter the building via three internal underground loading docks. The LOCD was used to measure 154 worker exposures on 3 days. Sampler performance was compared to a standard method at 15 fixed sites. The geometric mean (GM) of all 154 exposures was 7 ppm (geometric standard deviation (GSD) = 1.6); 10% of the exposures was 10 ppm or more. Dock Walkers and Forklift Operators had the highest exposures (maximum = 34 ppm) with GM (GSD) of 9 (1.7) and 9 (1.6) ppm, respectively. Attendants and Installer/Decorators had the lowest exposures with GMs of 6 (1.6) and 7 (1.4), respectively. The Cal/OSHA personal exposure limit for CO is 25 ppm time-weighted average (TWA).

AN - 69216097; 10537284 AB - We have uncovered a novel role for the cyclin-dependent kinase inhibitor, p57KIP2, during the immortalization of cultured human mammary epithelial cells (HMECs). HMECs immortalized after chemical carcinogen exposure initially expressed little or no telomerase activity, and their telomeres continued to shorten with passage. Cell populations whose mean terminal restriction fragment (TRF) length declined to < or = 3 kb exhibited slow heterogeneous growth and contained many nonproliferative cells. These conditionally immortal HMEC cultures accumulated large quantities of p57 protein. With continued passage, the conditionally immortal cell populations very gradually converted to a fully immortal phenotype of good uniform growth, expression of high levels of telomerase activity, and stabilization of telomere length. The fully immortal HMECs that grew well did not accumulate p57 in G0 or during the cell cycle. DNA and RNA analysis of mass populations and individual subclones of conditionally immortal HMEC line 184A1 showed that continued growth of conditionally immortal cells with critically short telomeres was repeatedly accompanied by loss of the expressed p57 allele and transient expression of the allele imprinted previously. Conditionally immortal 184A1 with mean TRF > 3 kb, infected with retroviruses containing the p57 gene, exhibited premature slow heterogeneous growth. Conversely, exogenous expression of human telomerase reverse transcriptase (hTERT), the catalytic subunit of telomerase, in 184A1 with mean TRF > 3 kb prevented both the slow heterogeneous growth phase and accumulation of p57 in cycling populations. These data indicate that in HMECs that have overcome replicative senescence, p57 may provide an additional barrier against indefinite proliferation. Overcoming p57-mediated growth inhibition in these cells may be crucial for acquisition of the unlimited growth potential thought to be critical for malignant progression.

A recently proposed fast/slow hypothesis states that a fast mechanism can only sense the instantaneous absolute value of the MF, and that a slow mechanism is potentially capable of sensing features such as frequency and relative orientation and magnitude of the field components. Here we applied the fast/slow hypothesis to a breast cancer model system: A 1.2 kT(rms), 60-Hz field inhibits tamoxifen's (TAM's) cytostatic action in MCF-7 cells via a MF interaction. We measured the growth of MCF-7 cells treated with TAM over 7 d, within different MFs: a sinusoidal, 60-Hz, 0.2-kT(rms) field; a sinusoidal, 60-Hz, 1.2-kT(rms) field; and a full-wave rectified version of the 1.2-kT(rms) sinusoidal field. A fast mechanism should not be able to distinguish between the latter two exposures. We observe that the rectified 1.2-kT field does not inhibit TAM's action, but that the 1.2-kT sinusoidal field does. Therefore, the 1.2-kT MF inhibition of TAM's cytostatic action operates via a relatively slow mechanism, and we predict that there exists a biologically dynamic complex capable of sensing a 1.2-kT, 60-Hz sinusoidal MF with an intrinsic time-scale of 17 ms or longer, the period of the 60-Hz applied field.

AN - 70827946; 10524433 AB - PURPOSEBoronated protoporphyrin (BOPP) is a candidate for use in both boron neutron capture therapy (BNCT) and photodynamic therapy (PDT) of glioblastoma multiforme (GBM). Our objectives are to identify factors that influence the uptake and retention of BOPP in vitro and to determine BOPP distribution in a human glioma cell line in vitro. This information will aid the development of compounds and treatment strategies that increase the effectiveness of BNCT therapy for GBM.METHODS AND MATERIALSThe amount, distribution pattern, and site of internalization of BOPP were assessed using fluorescence microscopy. Living human glioma (SF-767) cells were imaged after a 24-h exposure to BOPP (20-135.6 microg/ml, normal serum). Dose-dependent uptake of BOPP was determined using both fluorescence microscopy of individual living cells and inductively-coupled plasma-atomic emission spectroscopy (ICP-AES) analysis of cell pellets. Lysosome- or mitochondria-specific fluorescent probes were used to identify the cellular compartment containing BOPP. Two human fibroblast cell lines, AG-1522 (LDL receptor-positive) and GM019-15C (LDL receptor-deficient), were used to investigate LDL receptor-dependent BOPP uptake. The dependence of BOPP uptake on lipoproteins in the media was determined by exposing each of the three cell types to BOPP in medium containing either normal (NS) or lipoprotein deficient serum (LPDS).RESULTSBOPP accumulated in the lysosomes of human glioma cells in vitro, and not in the mitochondria, as reported for C6 rat glioma cells in vitro. BOPP uptake was concentration-dependent and was also dependent on the amount of lipoproteins in the medium. Over the range of incubation concentrations studied and at the single exposure duration time point investigated (24 h), all cells retained a similar amount of BOPP. At the lowest incubation concentration (20 microg/ml, NS), the amount of boron retained was near 10(9) atoms per cell (15 microg B/g cells). Lysosomes containing high concentrations of BOPP were randomly distributed throughout the cytoplasm; however, larger lysosomes containing BOPP were concentrated around the cell nucleus. Little or no BOPP accumulated in the cell nucleus. At incubation concentrations of 20 and 40 microg/ml (24-h time point), BOPP uptake in SF-767 cells was reduced in LPDS compared with NS (66% reduction). A similar result was observed for normal human fibroblasts (AG-1522 cells, 40 microg/ml, 24 h). At 40 microg/ml, in both NS and LPDS at 24 h, BOPP accumulation in LDL receptor-deficient human fibroblasts (GM019-15C cells) was reduced relative to AG-1522 cells. BOPP accumulation in GM019-15C cells (40 microg/ml, 24 h) was not affected by serum lipoprotein levels.CONCLUSIONIn cell culture, BOPP is taken up by human glioma cells via the LDL pathway and is compartmentalized into cellular lysosomes. Knowledge of this mechanism of BOPP uptake and retention will be important in attempts to modify toxicity and efficacy of this drug.

The application of the VLB technology at the BNL site involved a surface-modified colloidal silica (CS), which gels upon addition of an appropriate electrolyte. Lance injection was used for the CS barrier emplacement. The lance injections occur in three stages: primary, secondary, and tertiary. The geometry of the barrier is based on the wedge model. The first design is based on optimization principles and determines the parameters that maximize uniformity and minimize permeability by minimizing an appropriate objective function while meeting the design criteria. These include a maximum hydraulic conductivity of 10 super(-7) cm/s and a minimum thickness of 1 m. The second design aims to meet the same criteria and reflects standard chemical grouting practices. The combined effects of the key design parameters (i.e., lance spacing, injection location and spacing, gel time, injection rate, and volume) on the barrier permeability are studied. The optimization-based design is shown to have a significantly better performance than the standard engineering design. The interpenetration of adjacent CS bulbs appears to be of critical importance in meeting the barrier specifications. The three-dimensional simulations show that the barrier performance depends heavily on the path by which the final state is achieved. The in situ field measurements of the barrier permeability are consistent with, and appear to validate, the model predictions.

The effect of spatial variability in the velocity field and the sorption kinetics are modeled to see the combined effect of the two processes on the spreading of the solute injected at a point in the aquifer. The main result of this work is a transport model based on a discrete formulation that includes local dispersion and leads to nonasymptotic behavior in the spreading of the plume in a direction normal to the mean flow velocity.

The two most popular models to explain g-ray bursts are the coalescence of two compact objects such as neutron stars or black holes, or the catastrophic collapse of a massive star in a very energetic supernova-like explosion. Here we show that, about three weeks after the g-ray burst of 26 March 1998, the transient optical source associated with the burst brightened to about 60 times the expected flux, based upon an extrapolation of the initial light curve. Moreover, the spectrum changed dramatically, with the colour becoming extremely red. We argue that the new source is an underlying supernova. If our hypothesis is true then this provides evidence linking cosmologically located g-ray bursts with deaths of massive stars.

Based on the theorem of potential and the principle of superposition, an analytical solution is derived in this study to calculate the capture zone for two arbitrarily located wells that pump water from a confined aquifer at an equal flow rate. The general two-well capture zone is composed of two sub-capture zones, one for each well. The shapes of the two sub-capture zones and their relative locations change with variations of the orientation and the separation of the two wells. The solution can be useful in verifying available numerical codes, as well as in solving practical field problems.

AN - 70048304; 10496217 AB - An RNA spin-labeling technique was developed using the well-characterized interaction between the HIV Rev peptide and the Rev response element (RRE) RNA as a model system. Spin-labeled RNA molecules were prepared by incorporating guanosine monophosphorothioate (GMPS) at the 5' end using T7 RNA polymerase and then covalently attaching a thiol-specific nitroxide spin label. Three different constructs of the RRE RNA were made by strategically displacing the 5' end within the native three-dimensional structure. Nitroxide-to-nitroxide distance measurements were made between the specifically bound RNA and peptide using electron paramagnetic resonance (EPR) spectroscopy. The dipolar EPR method can reliably measure distances up to 25 A, the calculation of which is derived from the 1/r3 dependence of the broadening of EPR lines in motionally frozen samples. This RNA-labeling technique, dubbed 5' displacement spin labeling, extends the usefulness of the dipolar EPR method developed for analysis of protein structure. The advantage of this technique is that it is applicable to large RNA systems such as the ribosome, which are difficult to study by other structural methods. JF - RNA (New York, N.Y.)

AN - 70034511; 10484327 AB - The cell adhesion molecule intercellular adhesion molecule-1 (ICAM-1) plays a pivotal role in inflammatory responses. Quercetin (3,3',4',5,7-pentahydroxyflavone), a naturally occurring dietary flavonol, has potent anti-inflammatory properties. The effect of quercetin on ICAM-1 expression induced by agonists phorbol 12-myristate 13-acetate (PMA) and tumor necrosis factor-alpha (TNF-alpha) in human endothelial cell line ECV304 (ECV) was investigated. Quercetin treatment downregulated both PMA- and TNF-alpha-induced surface expression, as well as the ICAM-1 mRNA levels, in ECV cells in a dose-dependent (10-50 microM) manner. Quercetin had no effect on PMA- or TNF-alpha-induced nuclear factor-kappaB (NF-kappaB) activation. However, under similar conditions a remarkable dose-dependent downregulation of activator protein-1 (AP-1) activation was observed. This decrease in AP-1 activation was observed to be associated with the inhibitory effects of quercetin on the c-Jun NH2-terminal kinase (JNK) pathway. These results suggest that quercetin downregulates both PMA- and TNF-alpha-induced ICAM-1 expression via inhibiting both AP-1 activation and the JNK pathway.

A method is described for higher Se isotope ratio precision measurements using < or = 500 ng Se, and combining double-spike corrected TIMS analysis and purification by hydride generation. Fractionation experiments indicate strong fractionation during selenate reduction to selenite, little or no fractionation for selenite sorption, oxidation of reduced Se in soils, and Se volatilization by algae and soil samples. Selenate reduction and selenite reduction are the major Se istope fractionating processes.

The apparatus is analogous to the Reid vapor pressure apparatus that is used for vapor pressure measurement of light hydrocarbons. This system overcomes many of the shortcomings experienced when the Reid method is applied to heavy crudes. We explain the operation of the system and present results from measurement of heavy crudes from Southern California. Measurements on oil samples collected from storage tanks agreed well with analysis of headspace gases in the tanks.

Although oceans, biomass burning, and industrial production are identified as the major sources, the fraction of CH3Br that is contributed by each source is not well known. A mass-balance approach that exploits differences in the carbon isotopic signature (delta 13C) of CH3Br sources and sinks may provide a means of reducing uncertainties in the atmospheric budget. This approach depends on the distinctiveness of industrially produced methyl bromide. Our delta 13C measurements of industrial CH3Br from the three largest manufacturers worldwide yield a weighted average of -54.4 per thousand relative to the Peedee Belemnite standard. This result suggests that industrial CH3Br is isotopically distinct and that the carbon isotopic composition of atmospheric CH3Br may indicate what fraction of atmospheric CH3Br is anthropogenic.

In contrast to many mammalian receptors which signal by oligomerizing upon ligand binding, the chemotaxis receptors are dimeric even in the absence of their ligands, and their signalling does not depend on a monomer-dimer equilibrium. Bacterial chemotaxis receptors are composed of a ligand-binding domain, a transmembrane domain consisting of two helices TM1 and TM2, and a cytoplasmic domain. All known bacterial chemotaxis receptors have a highly conserved cytoplasmic domain, which unites signals from different ligand domains into a single signalling pathway to flagella motors. Here we report the crystal structure of the cytoplasmic domain of a serine chemotaxis receptor of Escherichia coli, which reveals a 200 angstrom-long coiled-coil of two antiparallel helices connected by a "U-turn". Two of these domains form a long, supercoiled, four-helical bundle in the cytoplasmic portion of the receptor. JF - Nature AU - Kim, K K AU - Yokota, H AU - Kim, S-H AD - Dep.

Well-characterized samples of vermiculite and hydrobiotite were exposed to aqueous uranyl under conditions designed to promote surface sorption either at fixed charge ion-exchange sites or at amphoteric surface hydroxyl sites. The local structure of uranium in the sorption samples was directly measured using uranium L (sub 3) -edge extended X-ray absorption fine structure (EXAFS). Polarized L (sub 1) - and L (sub 3) -edge X-ray absorption near-edge structure (XANES) measurements were used to characterize the orientation of uranyl groups in layered samples. X-ray diffraction (XRD) measurements of interlayer spacings were used to assess the effects of ion-exchange and dehydration upon the mineral structure. The most significant findings are: (1) Under conditions which greatly favor ion-exchange sorption mechanisms, uranyl retains a symmetric local structure suggestive of an outer-sphere complex, with a preferred orientation of the uranyl axis parallel to the mineral layers; (2) Upon dehydration, the ion-exchange complexes adopt a less symmetric structure, consistent with an inner-sphere complex, with less pronounced orientation of the uranyl axis; and (3) For conditions which favor sorption at surface hydroxyl sites, uranyl has a highly distorted equatorial shell, indicative of stronger equatorial ligation, and the detection of a neighboring U atom suggests the formation of surface precipitates and/or oligomeric complexes.

The existence of each trace metal at the single site in the bulk crystal is significant in view of previous studies showing that these trace elements are incorporated differentially at multiple, structurally distinct surface sites occurring in nonequivalent growth steps on calcite surfaces. The octahedral coordination for Ba is particularly noteworthy because of its large size (35% larger than host Ca) and the fact that it rarely exists as a major constituent with such a low coordination number. Analysis of the local distortion and relaxation around the impurities shows a nearly complete contraction of the structure around Co (super 2+) and Zn (super 2+) . The Co-O and Zn-O first-shell distances are only slightly longer than in CoCO (sub 3) and ZnCO (sub 3) , with a site compliance of approximately 80-90%. Displacements of higher shells relative to those in calcite decrease rapidly, but irregularly, over a short distance, and the relaxation may be largely confined within 6-7 Aa of the impurity. The dilation around the large Pb (super 2+) and Ba (super 2+) ions in calcite also shows a high degree of site compliance (85-90%). Relaxation around Pb and Ba also appears to be restricted, but extending further for Ba than for Pb. The limited observations suggest that compliance of the octahedral site in calcite is larger than for the cation site in the rocksalt structure. The high compliance for the metal site in calcite may reflect the corner-sharing topology of the structure and is also probably the reason that calcite shows such a wide range of isovalent substitutions in nature. The findings also provide a direct indication of the local strain associated with a dilute substitutional solid solution.

As the air component flows mainly in the heterogeneous fracture system, air-injection tests can be used to determine the hydrological properties and parameters of the fracture networks. In situ air-injection tests have been carried out in 30 boreholes drilled in a fractured rock block of 13 X 21.5 X 18 m (super 3) in the underground facility at Yucca Mountain. These in situ field tests consist of a constant rate flow injection in one of the boreholes, while the pressure response is monitored in all 30 boreholes of the rock block. This paper presents a simultaneous inversion for 21 air-injection tests in 21 separate boreholes using TOUGH2, a three-dimensional numerical code for multiphase, multicomponent transport [Pruess, 1991; Pruess et al., 1996]. Spatially variable fracture permeability is used as an adjustable parameter to fit the measured pressure responses. For most of the pneumatic experiments the calculated pressure changes match the measured data well. Estimated permeabilities range over 5 orders of magnitude, from 10 (super -15) to 8 X 10 (super -11) m (super 2) , indicating large spatial variability in permeability of the heterogeneous fracture system.

PAHs are recalcitrant, hydrophobic compounds and sorption to biological solids may be a significant mechanism for the removal of PAHs from refinery wastewater. The goal of this research was to investigate PAH sorption by bacterial biomass and examine the relationship between PAH biosorption and biodegradation. In this study, phenanthrene was used as a model PAH for biosorption studies and pyrene and fluoranthene were used as model compounds in biodegradation studies. It was found that phenanthrene biosorption varied with bacterial genus and species. Bacteria with the highest sorption capacity (K sub(p)) belong to the Nocardioforms, organisms that often cause solids separation problems in activated sludge plants. Consequently, blooms of these difficult to settle organisms in refinery treatment plants could exasperate PAH releases to the environment. The measured sorption capacities were reproducible and appeared to represent surface sorption, based on the apparent competition between naphthalene and phenanthrene for sorption sites. Based on a comparison of K sub(p) values, pure bacterial cultures can serve as valid models of biosorption by activated sludge MLSS. Finally it was found that PAH sequestration by high K sub(p), non-degraders has a significant impact on PAH biodegradation. The results of this study suggest that although biosorption can decrease the rate of PAH biodegradation in the short term, it can also result in the removal of PAHs from the wastewater and PAH retention in the treatment system where it may be ultimately biodegraded. This research improves our understanding of processes contributing to PAH degradation in petroleum refinery wastewater treatment plants.

Measurements of sodium chloride and ammonium sulfate aerosols were performed for comparison. Our experimental approach involved producing single component aerosol particles of a known size, and measuring the fraction of aerosol number concentrations (CN) that act as CCN at several supersaturations. The particle diameter (D sub(50)) at which the CCN/CN ratio of 0.50 is reached is defined as the critical, or activation, diameter. These experimentally derived diameters are compared with the theoretical critical diameter (D sub(C)). The results indicate that highly water-soluble organic compounds exhibit critical diameters that approach that of ammonium sulfate.

In 1998, the program saved about 0.5 billion kWh through the distribution of tools, case studies, and information on best practices and technology. That figure is expected to rise to more than 1.7 billion kWh in 2000. Pumps, which collectively use more electricity than any other single type of equipment, have been one of the program's primary targets. This article focuses on potential energy efficiency improvements in systems with centrifugal pumps.

This paper presents analytical solutions for air flow in faulted vadose zones of large or small thicknesses. The focus is on those sites where the fault zone is more permeable than its adjacent rock matrix. On the basis of the assumptions of a two-dimensional air flow in the matrix and a one-dimensional air flow in the fault zone, analytical solutions are presented for a sinusoidal atmospheric pressure variation. A procedure is then provided for extending the application of the solutions to an arbitrary atmospheric pressure variation. The solutions can help determine air permeability of leaky faults in the vadose zone.

Efficiency of the chemical speciation and water--rock--gas interaction calculations is important for modeling field-scale multidimensional reactive transport problems. An improved efficient model, REACT, for simulating water--rock--gas interaction under equilibrium and kinetic conditions, has been developed. In this model, equilibrium and kinetic reactions are solved simultaneously by Newton--Raphson iteration. The REACT speciation model was coupled with the multidimensional nonisothermal multiphase flow and mass transport code TOUGH2, resulting in the general purpose reactive chemical transport simulator TOUGHREACT. An application to supergene copper enrichment of a typical copper protore that includes the sulfide minerals pyrite (FeS sub(2)) and chalcopyrite (CuFeS sub(2)) is presented. The efficiency and convergence of the present model is demonstrated from this numerically difficult application that involves very large variations in the concentrations of oxygen, and sulfide and sulfate species. TOUGHREACT provides a detailed description of water--rock--gas interactions during fully transient, multiphase, nonisothermal flow and transport in hydrologically and geochemically heterogeneous media. The code is helpful for assessment of acid mine drainage remediation, geothermal convection, waste disposal, contaminant transport and water quality.

AN - 69838056; 10375668 AB - Single photon emission computed tomography (SPECT) and the dopamine (DA) transporter tracer, 2 beta-carboxymethoxy-3 beta-(4-iodophenyl)tropane ([123I]beta-CIT), were used to determine DA transporter density in 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP)-lesioned monkeys with varying degrees of parkinsonism. The clinical stage of parkinsonism corresponded to SPECT measures of striatal DA transporter density suggesting that more severe parkinsonism was associated with a greater degree of dopaminergic terminal degeneration. These findings are similar to those reported earlier using positron emission tomography (PET) and the DA metabolism tracer, 6-[18F]fluoro-L-m-tyrosine (FMT), indicating that both are good methods for evaluating nigrostriatal degeneration in MPTP primate models.

AN - 85251308; pmid-10354458 AB - The recently developed "microscope" based on a high-Tc dc SQUID (superconducting quantum interference device) is used to detect the magnetic fields produced by the motion of magnetotactic bacteria, which have permanent dipole moments. The bacteria, in growth medium at room temperature, can be brought to within 15 micron of a SQUID at liquid nitrogen temperature. Measurements are performed on both motile and nonmotile bacteria. In the nonmotile case, we obtain the power spectrum of the magnetic field noise produced by the rotational Brownian motion of the ensemble of bacteria. Furthermore, we measure the time-dependent field produced by the ensemble in response to an applied uniform magnetic field. In the motile case, we obtain the magnetic field power spectra produced by the swimming bacteria. Combined, these measurements determine the average rotational drag coefficient, magnetic moment, and the frequency and amplitude of the vibrational and rotational modes of the bacteria in a unified set of measurements. In addition, the microscope can easily resolve the motion of a single bacterium. This technique can be extended to any cell to which a magnetic tag can be attached.

AN - 69914396; 10416266 AB - The derivation of the optimal design for an upcoming toxicokinetic study of butadiene in humans is presented. The specific goal of the planned study is to obtain a precise estimate of butadiene metabolic clearance for each study subject, together with a good characterization of its population variance. We used a two-compartment toxicokinetic model, imbedded in a hierarchical population model of variability, in conjunction with a preliminary set of butadiene kinetic data in humans, as a basis for design optimization. Optimization was performed using Monte Carlo simulations. Candidate designs differed in the number and timing of exhaled air samples to be collected. Simulations indicated that only 10 air samples should be necessary to obtain a coefficient of variation of 15% for the estimated clearance rate, if the timing of those samples is properly chosen. Optimal sampling times were found to closely bracket the end of exposure. This efficient design will allow the recruitment of more subjects in the study, in particular to match prescribed levels of accuracy in the estimate of the population variance of the butadiene metabolic rate constant. The techniques presented here have general applicability to the design of human and animal toxicology studies.

AN - 69806698; 10359596 AB - The erythroid membrane cytoskeletal protein 4.1 is the prototypical member of a genetically and topologically complex family that is generated by combinatorial alternative splicing pathways and is localized at diverse intracellular sites including the nucleus. To explore the molecular determinants for nuclear localization, we transfected COS-7 cells with epitope-tagged versions of natural red cell protein 4.1 (4.1R) isoforms as well as mutagenized and truncated derivatives. Two distant topological sorting signals were required for efficient nuclear import of the 4.1R80 isoform: a basic peptide, KKKRER, encoded by alternative exon 16 and acting as a weak core nuclear localization signal (4.1R NLS), and an acidic peptide, EED, encoded by alternative exon 5. 4.1R80 isoforms lacking either of these two exons showed decreased nuclear import. Fusion of various 4.1R80 constructs to the cytoplasmic reporter protein pyruvate kinase confirmed a requirement for both motifs for full NLS function. 4.1R80 was efficiently imported in the nuclei of digitonin-permeabilized COS-7 cells in the presence of recombinant Rch1 (human importin alpha2), importin beta, and GTPase Ran. Quantitative analysis of protein-protein interactions using a resonant mirror detection technique showed that 4.1R80 bound to Rch1 in vitro with high affinity (KD = 30 nM). The affinity decreased at least 7- and 20-fold, respectively, if the EED motif in exon 5 or if 4.1R NLS in exon 16 was lacking or mutated, confirming that both motifs were required for efficient importin-mediated nuclear import of 4.1R80.

Samples of grouted sand were made by pouring sand into liquid grout in molds, with the grout diluted to concentrations ranging from 5 to 27% silica by weight. The unconfined compressive strength of the grouted sand, measured after 7 days, was proportional to the silica concentration, up to a maximum of 400 kPa. The hydraulic conductivity of the grouted sand decreased with increasing silica concentration in a nearly log-linear manner down to a minimum of 2X10 (super -9) cm/s, and was below 1X10 (super -7) cm/s for grouts with 7.4% silica or more. Inclusion of 5% volumetric saturation of organics (tetrachloroethene, CCl (sub 4) , or aniline) in the samples had little effect on the strength or hydraulic conductivity. Samples were immersed in test liquids (organics, HCl diluted to pH 3, distilled water saturated with organics, and distilled water control) for up to 1 year. All samples increased in strength except for those immersed in aniline; samples immersed in water saturated with aniline were also weaker than control samples.

Coordination with the structural inspection process is an important component of how the results of this research will be put into practice. Passive fire protection needs to be evaluated for its ability to contain a fire with limited fire fighting capability. Consideration should also be given to the concept that certain occupancies may not be safe in some structures while these same structures could be safely used for other occupancies. Another important area of study is the exterior passive fire protection. The envelope of a structure can be more vulnerable to a fire if the building has been "pounded" by impact with adjacent structures. In this report we assume that the postearthquake safety evaluation is being conducted by a "rapid evaluation team" which, in the first instance, identifies both the apparently safe and the obviously unsafe structures and then proceeds to evaluate more difficult damage conditions.

For an 8 m receiver offset we find that the relative dielectric constant cannot be resolved for frequencies below 500 kHz in a half-space. In the range of 500 kHz to 4 MHz, the relative dielectric constant for a half-space cannot be resolved for resistivities below approximately 200 Omega m. As frequency increases above 4 MHz the dielectric constant can be resolved for increasingly conductive material. A radial basis function neural network is used to analyze large numbers of half-space models to determine the best set of frequencies and receiver offsets to produce the most accurate estimates of resistivity and dielectric constant. For an 8 m receiver offset the ellipticity value over a half-space is never less than -0.447 for a frequency range between 31 kHz and 2 MHz. For two-layer earth models we find that the relative dielectric constant of the second layer cannot be resolved for our frequency range using a modular neural network. Ellipticities from 2 frequencies are sufficient to determine a resistivity, but increasing the number of ellipticities using different frequencies and more than one separation improves the accuracy of resistivity and relative dielectric constant values.

Winds in this region are directed by summer and winter monsoons in addition to diurnal land-sea effects. An analysis of national Eritrean and historical Italian wind records indicated marginal wind resources in the central highlands near the Eritrean capital of Asmera. An analysis of wind speed records recorded at two sites in the southern port city of Aseb indicate mean annual 10-m wind speeds of 9.5 m s super(-1) at the windier site. Surface wind speed records for the Red Sea suggest that similar potential may be found along the lower 200 km of the Eritrean coastline. Based on these findings, wind-generated electricity in this region should be substantially cheaper than the current supply generated from imported diesel.

These solutions account for diffusion in the pores, surface diffusion, mass transfer between the mobile and immobile water fractions, linear sorption (equilibrium or kinetic), and radioactive decay. Fully analytical solutions for both through-diffusion and reservoir depletion studies are obtained in the Laplace space, which are subsequently numerically inverted to provide the solution in time. The effects of the various diffusion, sorption, and geometric parameters on the solutions under both equilibrium and kinetic linear sorption are investigated. The semianalytical solutions are coupled with an optimization algorithm for parameter estimation, and diffusion and sorption parameters are determined using experimental data. The sernianalytical solutions are shown to have significant advantages over the conventional graphical approach because (1) they are not based on the often invalid assumption of constant upstream and negligible downstream concentrations, (2) they double the amount of data from which to extract the pertinent diffusion and sorption parameters, and (3) they allow differentiation between equilibrium and kinetic sorption.

AN - 69804707; 10350517 AB - The effectiveness of various tracers for measurements of exposure to environmental tobacco smoke (ETS) as a complex chemical mixture is based on the physicochemical properties of four major organic components and their dynamic behavior in indoor environments. For the particulate matter (PM) component and the very volatile organic compounds, emission and ventilation rates are generally the most important processes controlling indoor concentrations and exposures of nonsmokers. For the volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs), sorption on and desorption from indoor surfaces are additional processes that influence exposures. Laboratory and modeling studies of the dynamic behavior of nicotine, an SVOC, and PM indicate that nicotine can be used to estimate PM exposures from ETS in indoor environments when certain criteria are met: (italic>a(/italic>) smoking occurs regularly in the environment, (italic>b(/italic>) the system is near quasi-steady state, and (italic>c(/italic>) sampling time is longer than the characteristic times for removal processes. Measurements in residential and workplace buildings also support the use of nicotine as a tracer for PM in ETS. Recent laboratory and field data indicate that the VOCs from ETS can be traced using compounds with similar physicochemical properties, such as 3-ethenylpyridine, pyrrole, or pyridine. The effectiveness of nicotine for estimating exposures to the VOCs and SVOCs has not been determined, although these constitute major mass fractions of ETS.

AN - 69772065; 10338006 AB - Alanine scanning mutagenesis of the HyHEL-10 paratope of the HyHEL-10/HEWL complex demonstrates that the energetically important side chains (hot spots) of both partners are in contact. A plot of deltadeltaG(HyHEL-10_mutant) vs. deltadeltaG(HEWL_mutant) for the five of six interacting side-chain hydrogen bonds is linear (Slope = 1). Only 3 of the 13 residues in the HEWL epitope contribute >4 kcal/mol to the free energy of formation of the complex when replaced by alanine, but 6 of the 12 HyHEL-10 paratope amino acids do. Double mutant cycle analysis of the single crystallographically identified salt bridge, D32H/K97, shows that there is a significant energetic penalty when either partner is replaced with a neutral side-chain amino acid, but the D32(H)N/K97M complex is as stable as the WT. The role of the disproportionately high number of Tyr residues in the CDR was evaluated by comparing the deltadeltaG values of the Tyr --> Phe vs. the corresponding Tyr --> Ala mutations. The nonpolar contacts in the light chain contribute only about one-half of the total deltadeltaG observed for the Tyr --> Ala mutation, while they are significantly more important in the heavy chain. Replacement of the N31L/K96 hydrogen bond with a salt bridge, N31D(L)/K96, destabilizes the complex by 1.4 kcal/mol. The free energy of interaction, deltadeltaG(int), obtained from double mutant cycle analysis showed that deltadeltaG(int) for any complex for which the HEWL residue probed is a major immunodeterminant is very close to the loss of free energy observed for the HyHEL-10 single mutant. Error propagation analysis of double mutant cycles shows that data of atypically high precision are required to use this method meaningfully, except where large deltadeltaG values are analyzed.

AN - 69752118; 10321038 AB - Transmission soft X-ray microscopy is now capable of achieving resolutions that are typically 5 times better than the best-visible light microscopes. With expected improvements in zone plate optics, an additional factor of two may be realized within the next few years. Despite the high resolution now available with X-ray microscopes and the high X-ray contrast provided by biological molecules in the soft X-ray region (lambda = 2-5 nm), molecular probes for localizing specific biological targets have been lacking. To circumvent this problem, X-ray excitable molecular probes are needed that can target unique biological features. In this paper we report our initial results on the development of lanthanide-based fluorescent probes for biological labeling. Using scanning luminescence X-ray microscopy (SLXM, Jacobsen et al., J. Microscopy 172 (1993) 121-129), we show that lanthanide organo-polychelate complexes are sufficiently bright and radiation resistant to be the basis of a new class of X-ray excitable molecular probes capable of providing at least a fivefold improvement in resolution over visible light microscopy. Lanthanide probes, able to bind 80-100 metal ions per molecule, were found to give strong luminescent signals with X-ray doses exceeding 10(8) Gy, and were used to label actin stress fibers and in vitro preparations of polymerized tubulin.

AN - 69529063; 11989488 AB - Neutron fluences have been measured from 155 MeV/nucleon 4He and 12C ions stopping in an Al target at laboratory angles between 10 and 160 deg. The resultant spectra were integrated over angle and energy above 10 MeV to produce total neutron yields. Comparison of the two systems shows that approximately two times as many neutrons are produced from 155 MeV/nucleon 4He stopping in Al and 155 MeV/nucleon 12C stopping in Al. Using an energy-dependent geometric cross-section formula to calculate the expected number of primary nuclear interactions shows that the 12C + Al system has, within uncertainties, the same number of neutrons per interaction (0.99 +/- 0.03) as does the 4He + Al system (1.02 +/- 0.04), despite the fact that 12C has three times as many neutrons as does 4He. Energy and angular distributions for both systems are also reported. No major differences can be seen between the two systems in those distributions, except for the overall magnitude. Where possible, the 4He + Al spectra are compared with previously measured spectra from 160 and 177.5 MeV/nucleon 4He interactions in a variety of stopping targets. The reported spectra are consistent with previously measured spectra. The data were acquired to provide data applicable to problems dealing with the determination of the radiation risk to humans engaged in long-term missions in space; however, the data are also of interest for issues related to the determination of the radiation environment in high-altitude flight, with shielding at high-energy heavy-ion accelerators and with doses delivered outside tumor sites treated with high-energy hadronic beams.

The study is based on a two-dimensional (2-D) north-south vertical cross-section, using both the effective continuum and the dual-permeability modeling approaches. A study was also conducted on a three-dimensional (3-D) model using the effective continuum approach. The 2-D model conducted in 1996 uses a average uniform infiltration rate of 4.4 mm/year and a thermal load of 83 kW/acre. The 3-D model uses an spatially varying infiltration rate and a revised average thermal load of 87.6 kW/acre. For the rock properties used in the Topopah Springs (TSw) hydrogeological unit, heat pipe conditions develop above and below the repository in 10-100 years in both models. The average temperature of the boiling zone is about 96 degrees C. This boiling zone is confined to the TSw hydrogeological unit and lasts about 1000 years. At the top of the CHn (vitric/zeolitic interface), predicted maximum temperature is about 70-75 degrees C after about 2000 years. The model predicts a temperature increase of approximately 30 degrees C at the water table. The results show that thermal loading at the repository also results in significant changes in the moisture distributions at the repository horizon and the zone directly above and below it. A large increase in liquid and gas flux, several orders of magnitude above ambient conditions, is predicted near the repository. This study indicates the ECM and dual-k modeling approaches provide similar simulation results, in terms of temperature and moisture flow and distribution. The only difference is that at early times, the ECM model predicts more extensive boiling conditions. Localized dry-out is predicted in areas with low infiltration flux within the central part of the repository. However, because coarse grids were used, average saturation in the matrix blocks representing the repository indicates will remain high even when the regions near repository are completely dry. Analysis of the flux pattern at the top and bottom boundaries of the repository shows that the liquid always flows into the repository for most the thermal loading period (up to 10,000 years).

Modeling is conducted as part of a continuing effort (Wittwer et al., 1995; Bodvarsson and Bandurraga, 1996; Bodvarsson et al., 1997) using TOUGH2, a multiphase, integrated finite difference numerical model (Pruess, 1991) calibrated using available saturation, water potential and pneumatic data from six boreholes (Bodvarsson et al., 1997). Modeling results indicate that wetter future climatic conditions may increase lateral diversion above low permeability units of the Calico Hills nonwelded (CHn) hydrogeologic unit, and decrease lateral diversion above the Paintbrush nonwelded (PTn) hydrogeologic unit. The existence of lateral diversion above the CHn hydrogeologic unit is important if this diversion allow moisture to bypass altered zeolitic layers where radionuclides potentially released from the repository could be sorbed. Lateral diversion within the PTn hydrogeologic unit is important because it could redistribute the spatial distribution of net infiltration above the repository horizon. Nevertheless, no field evidence of lateral diversion in the PTn unit has been observed, suggesting that faulting or interface heterogeneities limit lateral flow. Collection and analysis of additional geochemical data may decrease uncertainty in capability of the PTn and altered CHn hydrogeologic units to create barriers to vertical flow, improving confidence in future climatic predictions.

Modeling studies are based on field investigations of the unsaturated zone (UZ) at Yucca Mountain, Nevada. Perched water data have been compiled, analyzed, and incorporated into a three-dimensional (3-D) UZ flow model developed to investigate perched water phenomena at Yucca Mountain. A conceptual model of perched water occurrences is discussed, and a series of comprehensive computer modeling studies on perched water at the site are presented. The model has been calibrated using perched water data observed in six boreholes, and reproduces water-perching conditions in the unsaturated zone of the mountain. Both steady-state and transient simulations have been conducted. The steady-state simulation results are in agreement with the observed perched water data, including water saturation and potential profiles and perched water elevations. Transient numerical pumping tests were performed using pumping testing data collected in the field from two boreholes. The numerical pumping test results match observed water levels collected during pumping and recovery periods.

A large number of boreholes have been drilled at the site, and an underground tunnel, the exploratory studies facility (ESF), has been constructed. A variety of boreholes and underground tests have been conducted that have provided large amounts of data from the UZ. This paper summarizes some of the current knowledge of geological and hydrological characteristics of the site and provides the framework for a series of technical papers that follow in this issue. A brief discussion is also given to the repository safety strategy for Yucca Mountain and the UZ site-scale flow model.

This poses difficult challenges for mathematical modeling. We summarize recent field observations of subsurface flow and transport from semi-arid regions, discuss alternative approaches for modeling fast preferential flow, and evaluate prospects for resolving current uncertainties. It is concluded that modeling of flow in fractured unsaturated zones is complex, but feasible, while modeling of transport processes is more difficult and less certain. We emphasize that successful modeling requires clear and specific objectives, but does not necessarily require a complete and detailed understanding of all processes and properties of a system. In order to achieve a robust modeling capability, as needed for engineering assessment and design of waste containment systems, it is suggested that two or more alternative modeling approaches be developed simultaneously for a given site.

The hydrogeologic parameters are calibrated using an inversion code (ITOUGH2) to fit measured core sample and in situ data according to statistical criteria. The available data include saturations, water potentials, pneumatic pressure records, and pore water age estimates based on geochemical analyses. Five 1-D columns are extracted from the 3-D site-scale model and used in an inversion that matches data from the five boreholes simultaneously. This results in layer-averaged fracture and matrix permeabilities and van Genuchten fitting parameters. The columns are then refined and individual inversions are performed with each 1-D model to develop a spatially varying parameter set. A number of sensitivity studies are performed to evaluate the effects of modeling assumptions on the calibrated parameters. Several fracture-matrix interaction formulations are also investigated during the study. The results show that the calibrated parameter set concluded to be most consistent with the conceptual model provides a good fit to the ambient data. The study also shows that the choice of the fracture-matrix interaction formulation has a significant effect on the calibrated parameter set.

A massive effort to collect data for characterization of the thermo-hydrologic behavior of the unsaturated zone is being conducted at the site. Several boreholes have been instrumented by the United States Geological Survey and the Nye County Nuclear Waste Repository Project Office for passive pneumatic monitoring of the subsurface. One-, two- and three-dimensional numerical models are used to simulate the observed subsurface pressure variations. The data are inverted using these models in order to characterize the unsaturated system and estimate the pneumatic diffusivity of important geologic features. Blind predictions of subsurface response and subsequent comparison to recorded data have built confidence in the models of Yucca Mountain. Inversions show that the pneumatic response of the system is dominated by the Paintbrush non-welded unit (PTn). Faults are shown to be fast pathways for gas flow but affect subsurface response only on a relatively local scale. Estimates of the diffusivity of the tuffs that comprise Yucca Mountain range from a low of 0.008 m super(2)/s in the non-welded pre-Yucca bedded tuff layer to a high of 4 m super(2)/s in the densely welded, fractured Topopah Spring tuff. Estimates of diffusivity in fault zones at Yucca Mountain range between 0.03 m super(2)/s and 1500 m super(2)/s with the highest being in the Drill Hole Wash fault where it intersects the Topopah Spring tuff.

Simulations of steady-state and transient moisture flow, transient gas flow, tracer transport, and thermal loading scenarios are performed, using a variety of numerical approaches to treat fracture-matrix (F-M) interactions, including an effective continuum model (ECM) and several varieties of dual-continua models. For the dual-continua models, we investigate the effect of varying the number of matrix gridblocks per fracture gridblock, the formulation applied for calculating F-M interface area, and whether or not global matrix-to-matrix flow occurs (dual-permeability vs. dual-porosity models). The key findings of the work based on a 1-D column are as follows. For steady-state moisture flow, most of the numerical and conceptual models provide similar results for saturation and fracture flow profiles. The ECM adequately models the steady-state processes because the system is not too far away from F-M equilibrium. For both transient moisture flow and transient transport in a steady flow field, the ECM is not adequate in general. Within the dual-continua models, the formulation for F-M interface area can have a major effect on the hydrodynamic response to an infiltration pulse and tracer arrival at various horizons, with fracture responses becoming earlier as F-M interface area decreases. The number of matrix blocks also has a significant effect on response time, with the more accurate multi-matrix-gridblock models yielding slower fracture response times. For transient gas flow arising from barometric pressure variations, the ECM adequately models the process, because F-M gas flow occurs rapidly compared to the time scale of the barometric pressure variations. For thermal loading, preliminary studies indicate that the ECM does not capture all the significant physical processes, because rapid fluid and heat flow can occur in the fractures before the matrix has a chance to equilibrate.

Coupled thermal-hydrological-mechanical-chemical processes in the fractured rock mass around the heater were monitored by numerous sensors emplaced among 30 boreholes. Periodic active testing of cross-hole radar tomography, neutron logging, electrical resistivity tomography, and interference air permeability tests probed the change of moisture content in the rock mass. Thermal-hydrological processes in the SHT have been simulated using a 3-D numerical model and compared to the monitored data. The good agreement between the temperature data and simulated results indicates that the thermal-hydrological responses of the SHT in the 9 months of heating are well-represented by the coupled thermal-hydrological numerical model. The dominant heat transfer process is by conduction and the signature of vapor and liquid counter flow is subtle in the temperature data. The simulated result of a dry-out zone of about 1 m (at the end of the heating phase) around the heater hole, and a condensation zone of increased liquid saturation outside of the dry-out zone, is consistent with the radar tomography and air permeability data. Tomography data and post-test laboratory measurements indicate that the moisture content is larger below than above the heater horizon, suggesting gravity drainage of condensate in the fractures. Model studies show that gravity drainage occurs in simulations using the dual permeability conceptual model, but is absent in the effective-continuum model, where matrix and fractures are required to be in thermodynamic equilibrium at all times.

The model takes into account the simultaneous flow dynamics of liquid water, vapor, air and heat in the highly heterogeneous, fractured porous rock in the unsaturated zone (UZ). This model is intended for use in the prediction of the current and future conditions in the UZ so as to aid in the assessment of the system performance of the proposed repository. The modeling approach is based on a mathematical formulation of coupled multiphase, multicomponent fluid and heat flow through porous and fractured rock. Fracture and matrix flow is treated using both dual-permeability and effective-continuum modeling approaches. The model domain covers a total area of approximately 43 km super(2), and uses the land surface and the water table as its top and bottom boundaries. In addition, site-specific data, representative surface infiltration, and geothermal conditions are incorporated into the model. The reliability and accuracy of the model have been the subject of a comprehensive model calibration study, in which the model was calibrated against measured data, including liquid saturation, water potential and temperature. It has been found that the model is generally able to reproduce the overall system behavior at Yucca Mountain with respect to moisture profiles, pneumatic pressure variations in different geological units, and ambient geothermal conditions.

The test results suggest that (1) a niche opening (short drift excavated for this study) acts as a capillary barrier; (2) a seepage threshold exists; and (3) the seepage is a fraction of the liquid released above the ceiling. Before seepage quantification, air injection and liquid release tests at two niche locations were conducted to characterize the fracture flow paths. Nearly two-order-of-magnitude changes in air permeability values were measured before and after niche excavation. The dyed liquid flow paths, together with a localized wet feature potentially associated with an ambient flow path, were mapped during dry excavation operations. After niche excavation, the seepage is quantified by the ratio of the water mass dripped into a niche to the mass released above the opening at selected borehole intervals. For the first set of five tests conducted at Niche 3650 site, the ratios range from 0% (no dripping for two tests) to 27.2%. Changes in flow path distributions and water accumulation near seepage threshold were observed on the niche ceiling. The seepage test results compare reasonably well with model results without parameter adjustments, using capillary barrier boundary condition in the niche and two-dimensional and three-dimensional conceptualizations to represent discrete fracture and fracture network for the flow paths. Model analyses of the niche tests indicate that the seepage is very sensitive to the niche boundary condition and is moderately sensitive to the heterogeneity of the fracture flow paths and to the strengths of matrix imbibition. Strong capillary strength and large storage capacity of the fracture flow paths limit the seepage. High permeability value also enhances diversion and reduces seepage for low liquid release rate.

Chloride concentrations in infiltrating water were calculated from aerial distributions of precipitation and infiltration rates for the current climatic conditions and for the last glacial maximum, combined with effective chloride concentrations in precipitation. Modeled concentrations are roughly similar to measured porewater chloride concentrations from the Paintbrush nonwelded tuffs in the Exploratory Studies Facility (ESF) tunnel and in boreholes suggesting that the mean infiltration rate over the site is unlikely to be higher than the calculated mean infiltration rate for the modem climate ( similar to 5 mm/year; [Flint, A.L., Hevesi, J.A., Flint, L.E., 1996. Conceptual and Numerical Model of Infiltration for the Yucca Mountain Area, Nevada. Milestone 3GU1623M. U.S. Geol. Surv. Water Res. Invest. Rep. U.S. Geological Survey, Denver, CO]). Porewaters from the late Pleistocene (> 10 ka) could be present in the Paintbrush bedded tuffs and in the underlying Topopah Spring welded tuffs (TSw), predominately under regions of thick alluvium having little infiltration. However, porewaters at the potential repository level may have a higher proportion of Holocene recharge due to the higher calculated infiltration rate in this region. Dual-permeability simulations show that in low infiltration regions chemical disequilibrium can exist between fracture and matrix porewaters, as a result of the climate change 10,000 years ago. Below the potential repository level, simulations show significant mixing due to lateral flow on top of the low permeability basal vitrophyre in the Topopah Spring unit and on zeolitized tuffs in the Calico Hills unit. Perched water chloride concentrations are closely matched using the calculated conditions for the last glacial maximum climate, with some component of Holocene recharge. Measured strontium concentrations in the UZ and in the perched water bodies can be roughly matched by assuming conservative behavior in nonzeolitic units and strong ion exchange in zeolitic units, and indicate that the perched water bodies are poorly mixed. Differences in the Cl contents of samples having a bomb-pulse Cl-36 signature and those with a modern ratio indicate that waters of intermediate super(36)Cl/Cl ratios may be mixtures, that without other isotopic data could be inferred as either Pleistocene or Holocene age waters.

A prediction of the seepage rate is particularly complicated for the potential repository site at Yucca Mountain, NV, which is located in a thick sequence of unsaturated, fractured tuffs. Underground openings in unsaturated media might act as capillary barriers, diverting water around them. In the present work, we study the potential rates of seepage into drifts as a function of predicted percolation flux at Yucca Mountain, based on a stochastic model of the fractured rock mass in the drift vicinity. A variety of flow scenarios are considered, assuming estimated present-day and predicted future climate conditions. We show that the heterogeneity in the flow domain is a key factor controlling seepage rates, since it causes channelized flow and local ponding in the unsaturated flow field. The rates of seepage are related in a complex non-linear manner to the rock properties, the size and shape of the drift, the degree of heterogeneity, and the assumed percolation scenario.

An "orthogonal" suppressor tRNA was derived from Saccharomyces cerevisiae tRNA sub(2) super(Gln). This yeast orthogonal tRNA is not a substrate in vitro or in vivo for any Escherichia coli aminoacyl-tRNA synthetase, including E. coli glutaminyl-tRNA synthetase (GlnRS), yet functions with the E. coli translational machinery. Importantly S. cerevisiae GlnRS aminoacylates the yeast orthogonal tRNA in vitro and in E. coli, but does not charge E. coli tRNA super(Gln). This yeast-derived suppressor tRNA together with yeast GlnRS thus represents a completely orthogonal tRNA/synthetase pair in E. coli suitable for the delivery of unnatural amino acids into proteins in vivo. A general method was developed to select for mutant aminoacyl-tRNA synthetases capable of charging any ribosomally accepted molecule onto an orthogonal suppressor tRNA. Finally, a rapid nonradioactive screen for unnatural amino acid uptake was developed and applied to a collection of 138 amino acids. The majority of glutamine and glutamic acid analogs under examination were found to be uptaken by E. coli. Implications of these results are discussed.

Upon phosphorylation by the TGFbeta receptors, Smad2 and Smad3 homoligomerize and heteroligomerize with Smad4, translocate to the nucleus and activate transcription of TGFbeta responsive genes. Smad3 and Smad4 have been shown to bind to various sites in the PAI-1 promoter. To determine the number of Smad-binding sites within the 94-base pair major TGFbeta-responsive region and the mechanism of Smad-mediated transactivation, we systematically mapped the Smad-binding sites and show that Smad4 and Smad3 bind cooperatively to two adjacent DNA elements in this region. Both elements were required for TGFbeta-induced, Smad3- and Smad4-dependent activation of PAI-1 transcription. Contrary to previous reports, transactivation of the PAI-1 promoter was mediated by the amino- but not carboxyl-terminal domains of the Smads. Furthermore, oligomerization of Smad3 markedly enhanced its binding to the two binding sites. Finally, a Smad4 mutation identified in a human pancreatic carcinoma that inactivates Smad4 signaling abolished Smad4 DNA binding activity, hence preventing transactivation of TGFbeta-responsive genes. These results underscore the importance of the Smad4 DNA binding activity in controlling cell growth and carcinogenesis.

The (super 132) Xe/ (super 36) Ar ratios are as high as approximately 576 times the ratio in air and represent the largest relative Xe-enrichments ever observed in terrestrial fluids. The Xe isotopic composition is indistinguishable from air. We show that these samples cannot be explained by equilibration of oil with air saturated water and secondary enrichment via a Rayleigh distillation gas stripping process. Based on laboratory studies of others with potential petroleum source rocks, we believe the source of this enriched heavy noble gas component was adsorbed air initially trapped in/on the source rocks that was expelled and mixed with the hydrocarbons during expulsion and primary migration. Kr and Xe enrichments decrease with increasing (super 36) Ar concentration. We propose a model in which an initial Kr-Xe-enriched hydrocarbon becomes diluted with noble gases extracted from air saturated groundwater during expulsion, migration, and storage. The model generates an integrated water/hydrocarbon ratio for the production fluid which indicates a minimal role for water in hydrocarbon expulsion and migration. The results are interpreted to provide time/geometrical constraints on the mechanisms by which hydrocarbons can migrate as a separate phase.

The extreme surface sensitivity of ARXPS permits concluding that the chemical composition of the near-surface region differs from the bulk because of the strong anisotropy of the margarite structure. Depth profiling was carried out by angle resolved spectroscopy that is a non destructive measuring technique. More grazing polar angles sample increasingly superficial layers of the margarite. The topmost layers are made up of C, due to the mineral/atmosphere interaction. At low grazing angles the concentration of Si increases, and both Al and Ca decreases; therefore we conclude that the tetrahedral sheet is the topmost monolayer. Repulsion between the octahedral and tetrahedral sheets is probably responsible for the cleavage. Photoelectron diffraction effects are also clearly evidenced by Si, Ca, and Al. Single-scattering cluster calculations were performed in simulating scanned angle core emission. The calculated patterns do not show a reasonable agreement with experimental data.

The simulated radial distribution functions then were used to compute the total radial distribution function for interlayer water, a physical quantity that can be determined experimentally by H/D isotopic-difference neutron diffraction. The simulated total radial distribution functions were compared with that for bulk liquid water, and with a total radial distribution function determined experimentally for the two-layer hydrate of Na-montmorillonite by Powell et al. (1997). This comparison suggested that water molecules in the two-layer hydrate of montmorillonite have nearest-neighbor configurations which differ significantly from the tetrahedral ordering of nearest neighbors that characterizes bulk liquid water.

We suggest that most such seepage proceeds in an unsteady, episodic manner in localized preferential pathways. Mechanisms are proposed and explored which permit water to flow relatively freely in networks of interconnected fractures in the presence of strong suction pressures from an unsaturated rock matrix. Imbibition into the rock matrix is reduced by limited wetted area, the episodic nature of flow, and possibly also by the presence of mineral coatings of low permeability on the fracture walls. These effects and conditions combine to limit total imbibition rates to values less than saturated matrix hydraulic conductivity, leaving the rock matrix in partially saturated conditions even as water is flowing freely in portions of the fracture network. The proposed conceptual model is elaborated and substantiated with analytical estimates and numerical simulation studies. Mechanisms are demonstrated that can funnel distributed seepage into spatially localized preferential paths. Subsequent horizontal broadening from dispersive mechanisms is found to be a slow process for fractures of high intrinsic permeability. The presence of an unsaturated rock matrix provides constraints on fracture-matrix interface areas for imbibition and on the frequency of episodic deep seepage events. Further studies are needed to test the proposed model.

AN - 70862390; 10097044 AB - Clay minerals are layer type aluminosilicates that figure in terrestrial biogeochemical cycles, in the buffering capacity of the oceans, and in the containment of toxic waste materials. They are also used as lubricants in petroleum extraction and as industrial catalysts for the synthesis of many organic compounds. These applications derive fundamentally from the colloidal size and permanent structural charge of clay mineral particles, which endow them with significant surface reactivity. Unraveling the surface geochemistry of hydrated clay minerals is an abiding, if difficult, topic in earth sciences research. Recent experimental and computational studies that take advantage of new methodologies and basic insights derived from the study of concentrated ionic solutions have begun to clarify the structure of electrical double layers formed on hydrated clay mineral surfaces, particularly those in the interlayer region of swelling 2:1 layer type clay minerals. One emerging trend is that the coordination of interlayer cations with water molecules and clay mineral surface oxygens is governed largely by cation size and charge, similarly to a concentrated ionic solution, but the location of structural charge within a clay layer and the existence of hydrophobic patches on its surface provide important modulations. The larger the interlayer cation, the greater the influence of clay mineral structure and hydrophobicity on the configurations of adsorbed water molecules.

These tools relay conformational states, conformational dynamics, and activity of single biological molecules to physical observables, unmasked by ensemble averaging. Distributions and time trajectories of these observables can therefore be measured during a reaction without the impossible need to synchronize all the molecules in the ensemble. The progress in applying these tools to biological studies with the use of fluorophores that are site-specifically attached to macromolecules is reviewed.

However, field conductivity data are usually measured at a different scale (usually smaller) than that of the gridblocks. The present paper describes an approach for upscaling to block-scale, which combines the rigorous result of small-value perturbation analysis with a plausible generalization of the first-order results to large variance. Steady-state flow through a block of stochastically heterogeneous medium, with constant values of the hydraulic head at the two opposite sides, is analysed. An upscaling rule and relationship is obtained between the local-scale hydraulic conductivity and the expected mean and variance of blockscale conductivity, where the block size is comparable with the correlation scale of the local conductivity field. The rather simple expressions that are obtained are validated using data from numerical experiments. Further, a generalized spatial power-averaging method to calculate the block-scale conductivity from values of local-scale conductivity is developed, in which the exponent value is given as a function of the ratios of flow domain dimensions to the respective correlation length.

Most of these surveys used a high frequency piezoelectric seismic source to obtain P-wave velocity tomograms. Additionally, we deployed a new type of borehole seismic source, know as an orbital vibrator, in a crosswell seismic survey as part of the subsurface characterization program at this contaminated groundwater site. This source, know as an orbital vibrator, allows simultaneous acquisition of P- and S-waves. The orbital vibrator was developed for oil field applications and, to our knowledge, this is the first environmental scale crosswell application. Both velocity and attenuation tomograms have been calculated. The velocity tomograms show a relationship to contaminant propagation in the groundwater (as measured by logs and cores). Zones of high contaminant flow are consistent with zones of low velocity (both P- and S-wave) and high attenuation. We believe horizontal fracture zones at the boundaries of basalt flows are controlling the contaminant flow and the seismic properties. Additionally, high amplitude guided waves are observed and we believe these waves delineate thin (1-2 m) zones of velocity contrast which relate to fracturing and, in some instances, coincide with contaminate flow.

An induced polarization (IP) survey of the CTP shows a very strong polarization anomaly and a modest resistivity response associated with the simulated waste. The data have been interpreted using a three-dimensional (3-D) inversion algorithm based on the simultaneous iterative reconstruction technique (SIRT) and finite difference forward modeling to form a subsurface model of complex resistivity. The edges of the waste zone are well resolved. Limited depth extent is recognized, though the bottom of the waste appears too deep. The intrinsic polarizability of the waste material has been estimated by means of a forward modeling experiment. The IP method holds promise as a technique to distinguish buried waste from pockets of conductive soil material, such as are present at the CTP.

The dielectric constant and amplitude attenuation values obtained from inversion of the radar data, as well as the seismic P-wave velocity values obtained from inversion of the seismic data, reveal similar spatial patterns. Comparison of this tomographic information with coincident wellbore logs suggest that the geophysical attributes are sensitive to hydrogeological variations. Information obtained from the radar tomography data were used to produce 2-D, high-resolution images of porosity and electrical conductivity. Comparison of these images with coincident log data reveal that these estimates are reasonable and suggests that the tomography data will be useful at this site for delineating variations in hydrological parameters.

Plane wave analysis is used to obtain a dispersion equation for the velocities of fracture channel waves. Analysis of this equation demonstrates that parallel fractures form an elastic waveguide that supports two symmetric and two antisymmetric dispersive Rayleigh channel waves, each with particle motions and velocities that are sensitive to the normal and tangential stiffnesses of the fractures. These fracture channel waves degenerate to shear waves when the fracture stiffnesses are large, to Rayleigh waves and Rayleigh-Lamb plate waves when the fracture stiffnesses are low, and to fracture interface waves when the fractures are either very closely spaced or widely separated. For intermediate fracture stiffnesses typical of fractured rock masses, fracture channel waves are dispersive and exhibit moderate to strong localization of guided wave energy between the fractures. The existence of these waves is examined using laboratory acoustic measurements on a fractured marble plate. This experiment confirms the distinct particle motion of the fundamental antisymmetric fracture channel wave (A (sub 0) mode) and demonstrates the ease with which a fracture channel wave can be generated and detected.

Intramolecular fluorescence resonance energy transfer and fluorescence polarization anisotropy measurements of fluorescently labeled staphylococcal nuclease molecules reveal distinct patterns of fluctuations that may be attributed to protein conformational dynamics on the millisecond time scale. Intermolecular fluorescence resonance energy transfer measurements provide information about the dynamic interactions of staphylococcal nuclease with single substrate molecules. The experimental methods demonstrated here should prove generally useful in studies of protein folding and enzyme catalysis at single-molecule resolution.

AN - 69571060; 9927445 AB - In vitro, the protein complex Chromatin Assembly Factor-I (CAF-I) from human or yeast cells deposits histones onto DNA templates after replication. In Saccharomyces cerevisiae, the CAC1, CAC2, and CAC3 genes encode the three CAF-I subunits. Deletion of any of the three CAC genes reduces telomeric gene silencing and confers an increase in sensitivity to killing by ultraviolet (UV) radiation. We used double and triple mutants involving cac1Delta and yeast repair gene mutations to show that deletion of the CAC1 gene increases the UV sensitivity of cells mutant in genes from each of the known DNA repair epistasis groups. For example, double mutants involving cac1Delta and excision repair gene deletions rad1Delta or rad14Delta showed increased UV sensitivity, as did double mutants involving cac1Delta and deletions of members of the RAD51 recombinational repair group. cac1Delta also increased the UV sensitivity of strains with defects in either the error-prone (rev3Delta) or error-free (pol30-46) branches of RAD6-mediated postreplicative DNA repair but did not substantially increase the sensitivity of strains carrying null mutations in the RAD6 or RAD18 genes. Deletion of CAC1 also increased the UV sensitivity and rate of UV-induced mutagenesis in rad5Delta mutants, as has been observed for mutants defective in error-free postreplicative repair. Together, these data suggest that CAF-I has a role in error-free postreplicative damage repair and may also have an auxiliary role in other repair mechanisms. Like the CAC genes, RAD6 is also required for gene silencing at telomeres. We find an increased loss of telomeric gene silencing in rad6Delta cac1Delta and rad18Delta cac1Delta double mutants, suggesting that CAF-I and multiple factors in the postreplicative repair pathway influence chromosome structure.

Volcanic glass that texturally appears unaltered is found to have delta (super 18) O and delta D values that are significantly higher than fresh volcanic glasses. The positive shift in delta (super 18) O and delta D values is proportional to the amount of hydration and chemical alteration of the glass samples. Initial hydration of the glass results in the exchange of Na for H: later hydration results in the loss of K and Fe in exchange for H and Na. The delta (super 18) O values of the most hydrated glass, and clay minerals from bentonite and metabentonite layers are approximately in equilibrium with slightly modified seawater. The delta D values of the hydrated glass, and clay minerals from bentonite and metabentonite layers, are significantly depleted in D relative to seawater and suggest meteoric exchange associated with tectonic uplift and erosion in the Pliocene and Pleistocene. Smectite from bentonite layers has delta (super 18) O and delta D values similar to the most hydrated glass samples, suggesting similar glass-water and smectite-water fractionation factors. Kaolinite and mixed-layered illite-smectite (I-S) altered from smectite have lower delta (super 18) O and higher delta D values than their precursor. The delta (super 18) O and delta D of nonvolcanic siliceous mudstones from the Pt. Arguello oil field show an unusual decrease in delta D with increasing burial depth that probably reflects the presence of organic hydrogen in the analyzed samples as well as possible D-depleted formation waters from detrital illite-water and hydrocarbon-water exchange.

An induced polarization (IP) survey of the CTP shows a very strong polarization and a modest resistivity response associated with the simulated waste. A three-dimensional (3-D) inversion algorithm based on the simultaneous iterative reconstruction technique (SIRT) and finite difference forward modelling has been applied to generate a subsurface model of complex resistivity. The lateral extents of the waste zone are well resolved. Limited depth extent is recognized, but the bottom of the waste appears too deep. With a modelling experiment, the intrinsic polarizability of the waste material is determined. Since IP is a technique for detection of diffuse occurrences of metallic material, this method holds promise as a method to distinguish buried waste from conductive soil material.

The amino acid sequences encoded by the PCR fragments, three RadA protein sequences previously published (21), and two new complete RadA sequences were aligned with representative bacterial RecA proteins and eucaryal Rad51 and Dmc1 proteins. The alignment supported the existence of four insertions and one deletion in the archaeal and eucaryal sequences relative to the bacterial sequences. The sizes of three of the insertions were found to have taxonomic and phylogenetic significance. Comparative analysis of the RadA sequences, omitting amino acids in the insertions and deletions, shows a cladal distribution of species which mimics to a large extent that obtained by a similar analysis of archaeal 16S rRNA sequences. The PCR technique also was used to amplify fragments of 15 radA genes from uncultured natural sources. Phylogenetic analysis of the amino acid sequences encoded by these fragments reveals several clades with affinity, sometimes only distant, to the putative RadA proteins of several species of Crenarcheota. The two most deeply branching archaeal radA genes found had some amino acid deletion and insertion patterns characteristic of bacterial recA genes. Possible explanations are discussed. Finally, signature codons are presented to distinguish among RecA protein family members.

The newly created Bose-Einstein condensates,--clouds of millions of ultracold, weakly interacting alkali-metal atoms that occupy a single quantum state--offer the possibility of investigating superfluidity in the weak-coupling regime. An outstanding question is whether Bose-Einstein condensates exhibit a mesoscopic quantum analogue of the macroscopic vortices in superfluids, and what its experimental signature would be. Here we report calculations of the low-energy states of a rotating, weakly interacting Bose gas. We find a succession of transitions between stable vortex patterns of differing symmetries that are in general qualitative agreement with observations of rotating superfluid helium, a strong-coupling superfluid. Counterintuitively, the angular momentum per particle is not quantized. Some angular momenta are forbidden, corresponding to asymmetrical unstable states that provide a physical mechanism for the entry of vorticity into the condensate.

Constant or spatially varying sorption kinetics can be modeled using the recursion approach. The sorption and desorption rates are modeled as two independent random processes with a prescribed mean and covariance structure with spatial variability in the rate parameters included as well. The recursion solution, in terms of the probability density function for solute travel times, is derived by specifying transition probabilities for moving between the aqueous and sorbed phases. A few simple examples are used to illustrate the approach. The computer implementation leads to a very rapid algorithm that is easily extended to cover cases beyond the basic model presented here.

The objectives of the paper are to evaluate the design of a transient, radial, multi-step outflow experiment, and to determine unsaturated hydraulic parameters using inverse modeling. We conducted numerical simulations, sensitivity analyses, and synthetic data inversions to assess the suitability of the proposed experiment for concurrently estimating the parameters of interest. We calibrated different conceptual models against transient flow and pressure data from a multi-step, radial desaturation experiment to obtain estimates of absolute permeability, as well as the parameters of the relative permeability and capillary pressure functions. We discuss the differences in the estimated parameter values and illustrate the impact of the underlying model on the estimates. We demonstrate that a small error in absolute permeability, if determined in an independent experiment, leads to biased estimates of unsaturated hydraulic properties. Therefore, we perform a joint inversion of pressure and flow rate data for the simultaneous determination of permeability and retention parameters, and analyze the correlations between these parameters. We conclude that the proposed combination of a radial desaturation experiment and inverse modeling is suitable for simultaneously determining the unsaturated hydraulic properties of a single soil sample, and that the inverse modeling technique provides the opportunity to analyze data from nonstandard experimental designs.

Direct transform of frequency domain EM fields to wavefield domain is known to be an ill-posed problem since the kernel of the integral transform is highly damped. In this study, instead of solving such an unstable problem, we approximate the wavefield in the transformed domain by ray series expansion. We further assume that reflected and/or refracted energy are weak enough to be neglected compared to that of direct wave, which is valid when the conductivity contrast between background medium and the target anomalous body is low. Picking of the peak arrival may then be reduced to computing the traveltime of direct wave which, in turn, to estimating the coefficients of the first terms in ray series expansion. The closed-form solution for vertical magnetic fields due to a vertical magnetic dipole source in a homogeneous whole space is shown to be the first terms in the series expansion. The adaptive simulated annealing scheme is used to estimate the coefficients of the ray series, which provided fast and stable results. We can extract the exact traveltime in the whole space with four-frequency data while the direct wavefield transform needs at least ten frequencies to show the correct event. The nonlinear traveltime tomography using thus extracted peak arrival times from the synthetic data shows reasonable images of the conductivity structure between boreholes.

It also becomes easy to disentangle uncertainty from variability, through hierarchical statistical modeling. Appropriate numerical techniques can be found, for example, in the recently developed arsenal of Markov chain, Monte Carlo simulations. The developments in this area can actually be viewed as extensions of the traditional or standard Monte Carlo methods for uncertainty analysis. Following a brief review of the techniques, examples of Bayesian analyses of physiologically-based pharmacokinetic models are presented for tetrachloroethylene and dichloromethane. The discussion touches on some open problems and perspectives for the proposed methods.

AN - 69393779; 10626220 AB - Numerous carcinogens or their bifunctional metabolites modify DNA bases by forming additional exocyclic rings on the base moiety. These modifications form exocyclic rings between N1 and N6 of dA, N3 and N4 of dC or N1 and N2 of dG, as well as the N2 and N3 of dG. This study focuses on the reaction products of dA and dC with chloroacetaldehyde, bis-chloroethyl nitrosourea and para-benzoquinone, which form etheno, ethano and para-benzoquinone derivatives, respectively. The three dC adducts and three dA adducts were each incorporated site-specifically into 25-nucleotide-long deoxyoligonucleotides. All duplexes with a single modified dA or dC adduct opposite the normal complement showed decreased thermal stability, as compared with the unmodified control duplex. The destabilizations ranges from -2 degrees C to -13 degrees C, depending on saturation, the size of the adduct and the nature of the base. Energy-minimized molecular models of the duplexes illustrate various degrees of distortions by the adducts, the para-benzoquinone adducts showing the greatest distortion.

AN - 69392885; 10626224 AB - Two human carcinogens that have been extensively studied are vinyl chloride and benzene. The active metabolites used in this study are chloroacetaldehyde (CAA) and para-benzoquinone (pBQ). Each forms exocyclic adducts between the N1 and N6 of A, the N3 and N4 of C and the N1 and N2 of G. Only CAA has been found to form the N2,3 adduct of G. CAA and pBQ adducts differ structurally in size and in the number of added rings, pBQ adding two rings to the base, while etheno bases have a single five-membered ring. The mechanism of repair of these two types of adducts by human enzymes has been studied in our laboratory with defined oligodeoxynucleotides and a site-specific adduct. The etheno derivatives are repaired by DNA glycosylase activity; two mammalian glycosylases are responsible: alkylpurine-DNA-N-glycosylase (APNG) and mismatch-specific thymine-DNA glycosylase. The former repairs 1,N6-ethenoA (epsilon A) as rapidly as the original substrate, 3-methyladenine, while the latter repairs 3,N4-ethenoC (epsilon C) more efficiently than the G/T mismatch. Our finding that there are separate enzymes for epsilon A and epsilon C has been confirmed by the use of tissue extracts from an APNG knockout mouse. As pBQ is much less efficient than CAA in modifying bases, the biochemical studies required total synthesis of the nucleosides. Furthermore, the pBQ adduct-containing oligomers are cleaved, to various extents by a different class of enzyme: human and bacterial N-5'-alkylpurine (AP) endonucleases. The enzyme incises such oligomers 5' to the adduct and generates 3'-hydroxyl and 5'-phosphoryl termini but leaves the modified base on the 5'-terminus of the 3' cleavage fragment ('dangling base'). Using active-site mutants of the human AP endonuclease, we found that the active site for the primary substrate, abasic (AP) site, is the same as that for the bulky pBQ adducts. There appears to be no clear rationale for the widely differing recognition and repair mechanisms for these exocyclic adducts, as shown for the repair of the same types of modification on different bases (e.g. epsilon A and epsilon C) and for completely unrelated lesions (e.g. AP site and pBQ adducts). Another important variable that affects the rate and extent of repair is the effect of neighbouring bases.

AN - 69389537; 10626211 AB - Benzene is a widely known carcinogen and a cause of bone-marrow toxicity and leukaemia in humans. para-Benzoquinone is a stable metabolite of benzene. Its reaction with deoxycytidine, deoxyadenosine and deoxyguanosine produces the major stable exocyclic compounds (3-hydroxy)-1,N4-benzetheno-2'-deoxycytidine, (9-hydroxy)-1,N6-benzetheno-2'-deoxyadenosine and (7-hydroxy)-1,N2-benzetheno-2'-deoxyguanosine, respectively, on a large scale and at high yield. The desired products were identified by fast atom bombardment-mass spectrometry, proton nuclear magnetic resonance and UV spectroscopy. These adducts were converted to the fully protected phosphoramidites and incorporated site-specifically into a series of oligonucleotides. 1,N6-Ethano-2'-deoxyadenosine is one of the exocyclic adducts formed during DNA reaction with the antitumour agent, 1,3-bis(2-chloroethyl)nitrosourea. This compound was synthesized on a large scale with a high yield (62%) and then was converted to the phosphoramidite and incorporated site-specifically into oligonucleotides. The coupling efficiency of the incorporation of all these adducts was high (> or = 93%). After de-protection and purification of these oligomers, enzymatic hydrolysis and analysis by high-performance liquid chromatography confirmed the presence of the adduct in the oligomers. These oligomers are being used to investigate the biochemical and physical properties of these adducts.

The solubility of high-valence cations increases with peralkalinity. Hafnium solubility has been determined for a wide range of compositions in which the degree of peralkalinity was varied. One composition (NIST SRM 1830; P = 0. 99) was chosen to compare Hf(IV) and U(IV) solubility, while a wide variety are planned to compare Pu(IV) and Hf(IV) solubility. The U oxidation state for SRM 1830 (reducing conditions) was determined as tetravalent by X-ray absorption spectroscopy. Solubility in all glasses was determined by noting the presence of crystals using either XRD or an optical microscope. Crystals of U (sub 3) O (sub 7) (or U (sub 2) O (sub 5) -UO (sub 2) ) precipitated from the U glasses and hafnia (HfO (sub 2) ) precipitated from the Hf glasses. The solubility limit of Hf in SRM 1830 is 9.86 mol% Hf. The solubility limit of U in the same glass, under oxidizing conditions is 6.73 mol% U(IV), and therefore, because we know that higher-valence U is more soluble in glass than lower-valence U, the solubility limit of U(IV) in the reduced SRM 1830 is less than 6.73 mol% and much less than the Hf limit. In the reduced glass, a U(IV)-O bond length of 2.32A and a coordination number of 7 for U(IV) were determined by extended X-ray absorption fine structure (EXAFS) spectroscopy. In contrast, the average Hf-O bond length in two similar peralkaline glasses is 2.04A (+ or -0.2), with a Hf coordination number of 6. These results indicate that Hf is not a good surrogate for U(IV). An EXAFS analysis of Hf-bearing SRM 1830 may strengthen this conclusion.

In the constraint the a priori information can be expressed by two limits: lower and upper bounds. This is a kind of inequality constraint, which is usually employed in linear programming. In this paper, we have derived this parameter constraint as a generalized version of positiveness constraint of parameter, which is routinely used in the inversion of electrical and EM data. However, the two bounds are not restricted to positive values. The width of two bounds reflects the reliability of ground information, which is obtained through well logging and surface geology survey. The effectiveness and convenience of this inequality constraint is demonstrated through the smoothness-constrained inversion of synthetic magnetotelluric data.

Results indicate that different uranyl species occur in the calcite and aragonite, with the principal difference found in the equatorial coordination of the linear uranyl moiety (O = U = O). In aragonite the coordination is by three bidentate CO3 groups and is similar to that for the aqueous uranyl triscarbonato complex, the dominant U(VI) species in the growth solutions. The XAFS spectra for aragonite also reveal Ca atoms at 3. 8-4. 7 Aa from the uranium. In contrast, the equatorial coordination of the O = U = O moiety in calcite has an oxygen shell at a closer distance (2.33 vs. 2.43 Aa) and apparently with fewer oxygens than in aragonite. Weak contributions from carbon and possibly additional oxygen atoms at 2.89-3.20 Aa indicate these are CO3 groups, but with a different configuration than in aragonite and in the aqueous uranyl species. No backscatterers are evident beyond approximately 3.2 Aa, suggesting disorder or possibly more than one structural environment in the calcite sample. Structural differences between aragonite and calcite, or their surfaces, influence the local coordination of the coprecipitated uranyl species. The equatorial coordination of the aqueous uranyl species remains largely intact during incorporation into aragonite, but undergoes a change during incorporation into calcite, possibly from bidentate to monodentate coordination. Although it is not possible to determine the exact positions of the uranyl species within the different carbonate structures, the observed local configurations around the U(VI) atoms must give rise to significant local disruption of the structure, which may affect the solubility of uranyl-containing calcite and aragonite. The apparent disorder in the calcite and its absences in the aragonite may also suggest that calcite is not well suited for the long-term sequestration of U(VI). And the metastability of aragonite also makes it unsuitable. These findings also offer insight to the observation that uranium is preferentially taken up by aragonite relative to calcite.

The samples were highly vesicular basalts (most samples contained greater than 50% vesicles) with 5-10% olivine phenocrysts up 4 mm in diameter. Visible organisms on surfaces of the rock were dominated by a pale greenish-gray fruticose lichen identified as Stereocaulon volcanii. Individual lichens were generally 2 mm or less in diameter. In the rock, the lichens penetrated to depths of as much as 5 mm, generally filling or lining vesicles. Within this biologically active zone, the rock was visibly oxidized to a reddish-brown, particularly in the area directly beneath the organisms. Olivine phenocrysts in these areas were variably altered and several unidentified secondary minerals were observed. Elemental maps of the lichens indicated that copper (and to a lesser extent zinc) was concentrated within the lichens. Higher concentrations of metals in the lichens were observed adjacent to small grains of Fe-oxide minerals in the rocks, possibly indicating that the lichens were preferentially breaking down Fe-oxide minerals (e.g., hematite, magnetite) in order to access high concentrations of trace metals contained in those minerals. Micro-XAFS analyses of copper in several of highest concentration regions of the lichens identified small (less than 10 microns in diameter) grains of copper metal at the core of the hot spots. These grains also contained high concentrations of metallic-like cobalt. Anomalous concentrations of cobalt were not observed in the elemental maps, but it is possible that it was masked by interference from iron (which was not observed in the metal grains).Uptake of metals by lichens has been observed by a number of researchers. For the most part, however, this has been limited to areas with anomalously high concentrations of metals (e.g., mine dumps). These studies indicate that Stereocaulon volcanii is capable of concentrating trace metals in pristine environments.

To investigate the metabolic controls on this large variation in isotope discrimination, we have used a mass-balance approach coupled with stable carbon isotope measurements of the residual CH (sub 4) , CO (sub 2) and cell biomass produced during laboratory chemostat experiments with pure cultures of type I and type II methanotrophs. We find that during oxidation and assimilation of methane, Methylomonas Methanica (type I) and Methylosinus trichosporium Ob3b (type II) both produce CO (sub 2) significantly depleted in (super 13) C relative to CH (sub 4) , with a maximum CH (sub 4) -CO (sub 2) fractionation greater than 30 per mil. The similarity of the d (super 13) C values of CO (sub 2) produced by these methanotrophs, under conditions of copper excess and copper limitation, demonstrates that there is little difference in the intrinsic fractionation factors for particulate vs. soluble MMO. However, differences in the carbon assimilation pathway of type I and type II organisms results in a large difference in biomass d (super 13) C values. For M. methanica, the d (super 13) C values of CO (sub 2) and biomass are nearly equivalent. In contrast, the d (super 13) C values of the biomass produced by M. trichosporium Ob3b is enriched in (super 13) C by approximately 16 per mil relative to CO (sub 2) throughout growth. However, regardless of MMO type or carbon assimilation pathway, the measured CH (sub 4) -CO (sub 2) and CH (sub 4) -biomass fractionation factors decrease dramatically during exponential growth. For example, although the CH (sub 4) -CO (sub 2) fractionation is larger than 30 per mil in the early stages of growth, it decreases to as little as 4-7 per mil during exponential growth. Thus, we will show that the magnitude of the overall CH (sub 4) -CO (sub 2) fractionation is directly correlated to variations in the CH (sub 4) utilization rate at different growth stages and that the CH (sub 4) -biomass fractionation can be predicted from the CH (sub 4) -CO (sub 2) fractionation and the carbon-assimilation pathway.

Data analysis of observed pressure buildups in injection and monitoring wells indicates non-linear flow behavior including pore-fluid redistribution and inertial flow, as well as the presence of constant pressure boundaries. A method for visualization of cross-well pressure connectivity was developed which reveals good connection within individual lava-flow units, but poor pressure response across rubble zones separating lava-flow units.

These tests were repeated after niche excavation. Increases of nearly two orders of magnitude were measured between the pre-excavation air-permeability values and the post-excavation air-permeability values. These increases could be interpreted as the opening of pre-existing natural fractures induced by stress releases associated with niche excavation. For the horizontal fractures above the niche, the effective fracture apertures increased with the unloading and removing of rock mass in the niche opening. The pre-excavation permeability distribution was used to characterize the initial fracture aperture distributions. Stress redistribution was evaluated with simple continuum models. The fracture opening and the corresponding fracture permeability increases associated with the stress releases were calculated. Calculated post- to pre-excavation permeability ratios compared well with the measured values for most of the borehole intervals.

Mass dispersion in a turbulent fluid has not been widely studied in the subsurface because most groundwater flow through porous media is assumed laminar. However, in aquifers characterized by large conduits and caverns the flow is not always laminar, as confirmed by recent U.S. Geological Survey studies in the Lower Floridan Aquifer. This provided the primary motivation for the study, as well as the current interest in aquifer storage and recovery technology. Theoretically, the transport of particles in nonlinear turbulent flow can be fully described by solving the governing differential equations if the turbulent velocity field is completely known (generally impossible). A semi-empirical velocity distribution equation, based on flow through parallel plates, has been developed to predict the advective transport component of the mass transport equation. Both flow and mass transport are simulated using a cylindrical coordinate system. Chemical tracer measurements conducted by the U.S. Geological Survey in the Lower Floridan Aquifer, Okeechobee County, Florida were used in the model calibration process.

The aquifer, comprised of up to 40 feet of sandy outwash, has a water table within 15 feet of land surface, and has highly variable hydraulic conductivities (4 to 192 feet per day) and organic-carbon contents (0.20 to 160 grams per kilogram). Shallow depths to ground water and relatively large hydraulic conductivities make the aquifer susceptible to leaching of fertilizers, pesticides, and volatile organic compounds discharged at the land surface. Water in the aquifer contains substantial concentrations of iron and manganese and has been affected by leachate from road de-icers (chloride and sodium). Recharge-age dating water samples with chlorofluorocarbon and tritium concentrations indicated that greater concentrations of nutrients, pesticides, and volatile organic compounds were detected in more recently recharged water to the aquifer. Concentrations of prometon, a long-lasting herbicide, were correlated to percentages of park land surrounding wells. Acetone and bromide were detected in greater concentrations in ground water near roadways, possibly due to emissions from gasoline combustion.

These radionuclides are present naturally in soils and rocks. Previous work in this laboratory has shown that radon is readily taken up from soil into vascular plants via the transpiration stream and eventually released into the atmosphere by diffusion through the leaf cuticle independent of water transport. We postulated that this process could be the basis of reducing radon transport into residential basements from the soil. Several important uncertainties in this concept are discussed here. Results of outdoor mesocosm experiments carried out with soil contaminated with Ra-226 are presented. A computerized plant water-uptake model was used to determine whether radon removal from soil by vegetation could be predicted at a specific site using a few soil and vegetation parameters. This work-in-progress indicates that on the order of 100 MBq per day may be removed per hectare of soil by transpiring vegetation.

Following a detailed hydrogeologic investigation to define the concentration, rate and extent of AN movement in the subsurface, a two-phase remediation program was implemented. The first phase consists of active removal of the highest concentrations of AN using extraction wells and off-site treatment of discharge water. The second phase passively monitors the effectiveness of natural attenuation of residual AN concentrations and provides necessary information to adjust the active removal system to insure minimal product migration. Periodic monitor well network sampling with analyses for AN, acrylamide, acrylic acid, acetic acid, propionic acid as well as other indicator parameters has confirmed consistent degradation of AN. Threshold concentrations below which significant AN degradation is initiated and decay half life variability of AN and degradation daughter products in ground water were determined. In less than two years, a five-fold decrease in AN ground water concentrations has been documented.

In NE Germany the discharge of ground water from quaternary deposits is one of the main components needed to describe the hydrologic and substance system. The development of a hydrogeological data model is therefore prerequisite for modeling the ground water component. GIS technologies make it possible to develop a method to describe the hydrogeological conditions of aquifer systems in regions of pleistocene deposits and in watersheds larger than 2000 km (super 2) by using available hydrogeological data and digital elevation models. The resulting data models are sufficiently accurate to describe the heterogeneity of the aquifer. The method was validated by investigations and calculations carried out in a pleistocene aged watershed covering 220 km (super 2) and applied for modeling ground water residence times in a mesoscale watershed (covering 2,400 km (super 2) ).

Performance evaluations and cost-benefit analyses were performed by US Naval Facilities Engineering Service Center (NFESC) at the Moffett Field site, which were sponsored by the Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP). The Moffett Field PRB uses a funnel-and-gate system design. The funnel is made of interlocking steel sheet piles and the gate consists of a reactive cell filled with zero-valent granular iron. Performance monitoring was conducted at the site to demonstrate the effectiveness of the PRB technology in capturing and remediating ground water that contained dissolved chlorinated hydrocarbon compounds. The primary contaminants of concern at Moffett Field in the vicinity of the PRB were trichloroethene (TCE), cis-1,2 dichloroethene (cDCE), and perchloroethene (PCE) at upgradient concentrations of about 2,900 micrograms per liter (ug/L), 280 ug/L, and 26 ug/L, respectively. Monitoring events included measuring water levels, testing field parameters, and ground-water quality sampling at about 75 monitoring points. Tracer tests using bromide solutions and flow-velocity meter testing were also completed in April and August 1997. Iron cell coring samples were collected and analyzed in December 1997 for early indications of chemical precipitation. The iron cell coring analyses and geochemical modeling from Moffett Field indicated that changes in inorganic chemistry may be caused by precipitation of calcium carbonates, iron-sulfide, and hydroxide compounds. Chemical precipitates are of significant concern because of the potential loss of reactivity and permeability in the iron cell. Long-term performance and life-expectancies of PRBs are generally unknown. The DoD ESTCP, Environmental Protection Agency (EPA), and Department of Energy (DOE) are sponsoring additional performance evaluations at several PRB sites to help find answers to the longevity concerns. In the meantime, these agencies are also attempting to help gain widespread regulatory acceptance and user confidence in implementing the PRB technology.

Water bearing strata in the basin and associated subbasins include consolidated bedrock units in the northern highlands, and Tertiary and Quaternary basin (bolson) fill units in the central to southernmost portions of the basin. Recharge occurs mostly from ephemeral recharge along mountain fronts and from infiltration beneath perennial streams. Under predevelopment conditions, ground water flowed north-to-south from the northern highlands, across the international border, to phreatic playas and alkali flats in Mexico where ground water discharged by evaporation. Extensive ground-water development has currently altered the directions of ground-water flow locally toward pumping centers near Deming and Columbus, New Mexico, and Palomas, Mexico. Hydrochemical facies in the basin developed as a result of water-rock interaction and evaporation along flowpaths. Hydrochemical facies vary from calcium-bicarbonate ground waters with total dissolved solids (TDS) less than 500 mg/L in the northern half of the basin, to sodium-bicarbonate ground waters with TDS greater than 500 mg/L in the central part of the basin, to sodium-sulfate and sodium-sulfate-chloride ground waters with TDS greater than 1,000 mg/L in the southernmost segment of the basin. Different hydrochemical facies and higher TDS developed as ground water flowed north-to-south. The primary processes responsible for hydrochemical evolution and salinization include gypsum and halite dissolution, exchange on clay particles of bound sodium for calcium and magnesium in solution, and evapotranspiration from vegetation and evaporative discharge at phreatic playas.

An overview of Quality Assurance requirements necessary to carry out field sampling methods and the laboratory analyses in Florida are provided in this communication. The underlying principles of sound Quality Assurance controls are discussed along with the components of the Quality Assurance Plan (QAP) framework. The approval process at the state and federal levels is also discussed. The need for QAP approvals for pesticide monitoring and analyses programs is a result of heightened awareness of Quality Assurance issues in this state. This discussion should prove to be useful to state and federal regulators, researchers and the members of the environmental surveillance teams.

Treated ground water is now a critical component of many municipal water supplies; at the same time ground water extraction often serves to control or minimize the spread of ground-water contamination. Although treated ground water can be safe and cost-effective, the associated costs and risks, particularly relative to surface water supplies, are not always understood by the general public or regulatory agencies. In Southern California, treated ground water is used by numerous municipalities to supplement potable water supplies. The systems for treating these supplemental supplies typically involve air stripping and/or granular activated carbon technologies to remove volatile organic compounds (VOCs). Although treating contaminated ground water is often considered too costly to be acceptable, the additional cost to remove low concentrations of VOCs typically ranges from $20 to $30 per acre-foot, while the overall cost of producing ground water, including replenishment or water district costs, is normally less than $200 per acre-foot. Available data indicate that treatment costs to remove VOCs are a minimal component of ground-water cost. In comparison, the overall cost for imported surface water typically is about $430 per acre-foot. The acute risk associated with using treated ground water to supplement potable water supplies is also minimal relative to surface water supplies. Ground water generally is of higher quality and has a lower risk of biological contamination than does surface water. The relatively low cost and risk of using treated contaminated ground water make it a sensible supplement to public water supplies.

It is space saving, pollutant removal effective, and pro ground water recharge. It is favorably used in highly urbanized areas where space is tight and soils are usually moderately to rapidly permeable. Infiltration facilities also become necessities to mitigate groundwater recharge impact by new development under local and state regulations. However, an infiltration trench design is more difficult than an open pond due to the complicated subsurface hydrogeologic conditions. Infiltration rate is determined not only by the permeability of the soil, but also by the geometry of the trench and the water depth in the trench. An accurate infiltration rate is critical for an appropriate design function for flood control and stormwater quality enhancement. However, to conduct a complete hydrogeologic study for every infiltration trench design would not be cost-effective for a small project. Therefore, a simple and practical method to determine realistically accurate infiltration rates will be very helpful for the design of small scale projects and the preliminary design of large scale projects. This paper presents a simple mathematical model of infiltration rate calculation for circular and rectangular shaped infiltration facilities. The model is verified by in-situ percolation tests, and provides satisfactory results. Some design recommendations are also discussed based on first hand design experience.

An adequate supply of potable water at reasonable cost is critical to the vitality of the area. Both resource managers and water suppliers are seeking to maintain sources of supply and the health of the ecosystem. Appropriate allocations of available resources that balance various demands are required. Even with ample water resources due to rainfall averages that exceed 50 inches per year, water resource management that accounts for the highly irregular temporal and spatial distribution of rainfall is critical to protect natural resources while providing reliable supplies. New approaches in water resource management are required, including advanced tools for simulation and analysis of hydrologic system behavior. To that end, Tampa Bay Water, a Regional Water Supply Authority has supported major consultant and staff efforts to develop an integrated surface water and groundwater (ISGW) model of the Central Northern Tampa Bay area. The model domain includes 11 wellfields that supply water to the six Member Government utilities. The integrated model is expandable to cover areas that may serve as future sources of water supply. Currently, the model uses rainfall data from 10 gages located throughout the area and simulates water withdrawals from all permitted wells within the area. Simulation results from the integrated model are used to develop an Optimized Regional Operations Plan (OROP) for the Agency's wellfields to minimize environmental impacts, meet the water supply requirements of the Member Governments, and satisfy Water Use Permit regulatory criteria.

The studies performed include: 1) Conceptual analysis of the injection site geological and hydrogeological conditions; 2) Evaluation of the impact of the different driving forces on contaminant transport; 3) Solution of calibration problem for hydrogeological properties distribution in Horizon I (the aquifer which hosts the intermediate-level LRW); 4) Simulation of contaminants migration in Horizon I taking into account hydraulic interaction with Horizon II (the aquifer above Horizon I containing the low-level LRW); 5) Solution of calibration problem for hydrogeological properties distribution in Horizon II; 6) Simulation of contaminant migration in Horizon II; 7) Sensitivity analysis of the potential impact of uncertainty in hydrogeological properties distribution on contaminant migration in Horizon I. The results of these studies indicate that for the normal evolution scenario, the potentially most hazardous LRW injected into Horizon I are reliably isolated from the biosphere for a period of no less than 1,000 years.

The flowline is oriented between the Diablo Plateau of western Texas and the Sierra de San Ignacio of northern Chihuahua, Mexico. Results of the cross-sectional model with geologically distributed values of permeability provided a good fit to the predevelopment potentiometric surface. Moderately-low recharge rates and travel times predicted by the model agree with published estimates and estimates derived by environmental isotopes. Model results suggest potential for some transboundary movement of ground water. The model was used to estimate recharge rates that are needed to establish flow capacity in the southeastern Hueco aquifer. Flow capacity is the maximum amount of water that a flow system can accept and transmit. Usually this results in regional saturation of the water table at land surface. Moisture is not available for flow capacity to be attained in the southeastern Hueco aquifer today, but flow capacity may have been established in the aquifer during the pluvial periods of the late Pleistocene Epoch. The recharge rates that are required to establish flow capacity in the numerical model are 293% higher than initial calibration recharge rates in the U.S. portion of the model. The recharge rates that are required to establish flow capacity in Mexico are 1,064% higher than initial calibration recharge rates.

A theoretical approach and a geochemical model of the forming of the (super 4) He/ (super 40) Ar-ratios are suggested. Quantitative estimates of these theoretical considerations are found to be in concordance with actual observations. For the time evolution of the (super 3) He/ (super 4) He-ratio a "bubble-model" of discharge is suggested. It is developed for conditions, when helium-traps are formed in boundary zones of the crystalline basement and the sedimentary envelope of the Tunka Depression of the Baikal Rift Zone. Tests of the model suggested were performed on a number of boreholes and springs, where actual data were received. This allowed to design methods of distinguishing helium and argon dissolved in water under natural condition or under technogenic impact.

A field demonstration designed to test remediation of aerobic shallow ground water that contains trichloroethene with cottonwood trees in a 0.2-hectare area at the Naval Air Station, Fort Worth, Tex. began in April 1996. Ground water was sampled in July 1997, November 1997, February 1998, and June 1998. Analyses from samples indicate that tree roots have the potential to create anaerobic conditions in the ground water that will facilitate degradation of trichloroethene by microbially mediated reductive dechlorination. Reduction of dissolved oxygen is the primary microbially mediated reaction occurring in the ground water beneath the planted trees. Dissolved oxygen concentrations, which varied across the site, were smallest near a mature cottonwood tree (about 20-years old) 60 meters southwest of the cottonwood plantings. Data indicate that methanogenesis is the most probable reaction occurring near the mature cottonwood tree. Reductive dechlorination either is not occurring or is not a primary process away from the mature tree. This conclusion is also supported by isotopic data of carbon-13 in trichloroethene at locations away from the mature tree, indicating that trichloroethene concentration is probably controlled by the physical process of volatilization from ground water into the unsaturated zone.

The catchment is 7 km (super 2) , contains two wetlands, and is drained by the Borschi stream. A constructed drainage system, beaver dams, and floodgates modify the natural water levels of the stream, and influence seasonal changes in the extent of flooded soils. Contributing pathways that are considered include ground-water transport, overland flow, interaction with stream bottom sediments, and surface connection between the Borschi stream and the wetlands. Evidence is presented that suggests the wetlands and seasonally-flooded soils are currently the main source of (super 90) Sr in the Borschi stream.

Intense alteration of portions of the mountain landscape led to severe changes in water and sediment regimes of many western rivers. Some long-abandoned mines and waste piles continue to pollute mountain streams. Water management structures and legal systems are other enduring legacies of nineteenth-century mining in the western states. Mining continues to be an active land use and a potential pollution source in various mountain regions of the West. Although regulation and technology have reduced the release of mining-related contaminants into streams and lakes, available technology is not widely implemented because of added costs. The larger-scale of some operations can provide the financial resources to control pollution but also creates the risk of large releases in the event of failure of pollution control techniques. This paper provides an overview of historical and current impacts of mining for metals on water resources in mountain ranges of the western states as well as a summary of efforts at controlling pollution. A novel regulatory approach to mine pollution recently adopted by Mono County in eastern California is described.

Transpiration, climate, soil-moisture, and tree-root data were collected and used to parameterize and validate the hydrologic model PROSPER, which was used to simulate evapotranspiration for a 12-year period and to determine the trees' uptake of contaminated water from the saturated zone (aquifer). Simulated annual evapotranspiration from the combined unsaturated and saturated zones ranges from 25 to 48 centimeters for the period when the tree plantations have achieved a closed canopy (year 12 and beyond), depending on assumptions regarding climatic conditions, soil-water availability, and root growth. Simulated annual uptake from the saturated zone for year 12 and beyond ranges from 12 to 28 centimeters. The ground-water flow model MODFLOW was used to simulate the effects of this predicted transpiration on ground-water flow in the aquifer. Although transpiration from the aquifer is predicted to reach between 50 and 90 percent of the initial volumetric flux of ground water through the demonstration site, the outflow of contaminated ground water from the site will likely be reduced by only 20 to 30 percent. The discrepancy between predictions for volume of water transpired from the aquifer and the reduction in volumetric outflow of contaminated ground water can be attributed to a predicted increase in ground water inflow to the site and the release of water from storage in the aquifer. It may be possible to achieve a greater amount of hydraulic control if additional trees are planted.

ER - TY - JOUR T1 - Contaminants modeling with TOX15 AN - 52103124; 2002-041751 AB - Control of toxics pollution in surface waters requires an adequate knowledge of transport and transformation phenomena which address these substances to their final fate; thus, the application of models could provide a quantitative assessment of their effects on the aquatic ecosystem. The Water Quality Analysis Simulation Program (WASP), which has been developed by US EPA, is one of the more widely applied modeling systems to study water quality problems in streams, lakes and estuaries. In this paper, TOXI5, which is the part of WASP addressed to toxics pollution problem, has been applied to a case study in a flooded limestone quarry located in Bedford County, Indiana, which has been previously polluted with equal quantities of the insecticides DDE and Lindane. The results obtained show a good agreement with field observations; particularly, model results point out the different removal mechanism for DDE and Lindane.

Typically, these impacts are evaluated in terms of increasing flood potential or degradation of water quality due to contamination. However, minimal attention is given to ground-water impacts associated with disturbance of surface coverage, which may lead to prevention of ground-water recharge, alteration of the ground-water elevation, diversion of ground-water flow, and adjustment in ground water/surface water interactions. This paper presents perspectives on ground-water impacts associated with changes in surface cover. The effects of altering surface cover are documented from three sites. Case study illustrates the effects of reduced ground-water recharge to a sensitive wetland from the development of a parking area for a large regional shopping mall. Case study #2 documents how ground-water flow patterns are altered by changing surface cover conditions. The third case study illustrates how computer models can be utilized to predict ground-water impacts due to alteration of the surface cover. The results of the paper indicate that urbanization may have significant impacts to the underlying ground-water system, and these ultimately may influence surface streams and ecological habitats.

EDYS (Ecological DYnamics Simulation) is a PC-based model designed to predict changes in ecological systems resulting from natural and anthropogenic stressors. EDYS consists of climate, soils, plant, animal, hydrological, spatial, landscape, disturbance and management modules. The soil module represents each horizon at the application site. The plant module includes above- and below-ground components for each species of interest. The disturbance module includes contaminants, drought, nutrient availability, herbivory, fire, trampling, shading, and competition. The hydrological module simulates precipitation, evapotranspiration, infiltration, runoff, erosion, and contaminant transport. The landscape module incorporates multi-scale simulations from small plots to entire watersheds. EDYS has been used in ERAs, impact assessments of environmental changes on erosion and water supply, and simulation of ecosystem responses to stressors at military reservations, mines, national parks, and watersheds in the United States and Australia. Applications for watershed invasion by juniper and for the US Air Force Academy are presented to illustrate landscape-level hydroecological responses to training, fire, drought, grazing, vegetation control, and revegetation.

Manipulation of the oxidation-reduction (redox) status of a vadose zone is a viable approach for in-situ remediation of a redox-sensitive contaminant like chromate. It was hypothesized that by creating a reducing zone through introducing a reductant into the vadose zone, the soluble and sorbed Cr(VI) will be reduced and precipitated resulting in an immobile and less toxic Cr(III) mineral phase. Therefore, the objective of this study was to evaluate potential reductants and their effectiveness to reduce highly Cr(VI)-contaminated soil or sediment samples collected from the vadose zone beneath the plating facility. The reductants evaluated were sodium dithionite, 1-ascorbic acid, and hydroxylamine. These reductants reduced chromate present in soils/sediments, and each provided a unique geochemical environment. Sodium dithionite proved to be the most effective reductant to detoxify chromate present in the vadose zone materials.

Risk assessment and risk management of arsenic contaminated sites requires a better understanding of arsenic-mineral interactions. Aluminosilicate minerals, such as feldspars and clays, are the most abundant constituents occurring in aquifer sediments, soils, and as suspended particles in ground water. Naturally occurring substances (e.g., iron, manganese, humic acid) can associate with minerals. Consequently, they could influence the behavior of alominosilicate minerals to arsenic adsorption. This laboratory work demonstrated that Fe and Mn oxide coatings on feldspar and kaolinite could alter the surface physicochemical properties of the minerals, causing an increase in the adsorption of arsenite and arsenate. Minerals treated with humic acid showed a significant decrease in the adsorption of As(V), but little change in the adsorption of As(III). The oxidation of As(III) to As(V) was significantly catalyzed by iodine ions associated with minerals, although present in trace amounts.

In June 1998, the agency signed the Partnership Agreement with the Southwest Florida Water Management District (SWFWMD) and the Member Governments to end decades of water litigation. The Optimized Regional Operations Plan (OROP) is a requirement of the new consolidated water use permit under the Agreement. The Operations Plan will outline the production schedule among eleven of the Agency's regional wellfields in such a way that effects to nearby wetlands and lakes will be minimized. To that end, an optimization model has been developed to maximize ground-water levels at a selected set of monitoring sites. Variations in water levels for a forecast period are accounted for by applying preferential weighting to monitoring sites according to their prevailing ground-water levels compared to established target levels. The current formulation includes the following: (1) meet demands for delivery of water at Points of Connection to Member Government systems; (2) meet regulatory requirements for production limits and minimum ground-water levels; (3) operate within physical constraints of the Agency's transmission and treatment systems; (4) account for spatial and temporal variability of rainfall influences on ground-water levels. The solution provides weekly pumping rates at each production well for the forecast period and the resultant transmission network flow to the Member Government Points of Connection. Details of the optimization model formulation, solution technique, and its implementation will be discussed.

It is often hypothesized that the interlayer region of low-order montmorillonite hydrates (up to three adsorbed water layers) can be pictured as a two-dimensional ionic solution. Our recent Monte Carlo and molecular dynamics simulations of interlayer configurations in the low-order hydrates of Li-, Na-, and K-Wyoming montmorillonite are examined comparatively in order to assess the accuracy of the ionic solution picture. The results indicate that local ordering of water molecules around the interlayer cations is indeed like that in a concentrated ionic solution. However, competition between the cations and water protons for negatively-charged sites in the clay layer, and between the cations and clay structural hydroxyls for itinerant water oxygens, also contribute significant complexity to the molecular structure of water in montmorillonite interlayers.

The purpose of the ESF Thermal Test is to acquire a more in-depth understanding of the coupled thermal, mechanical, hydrological, and chemical processes likely to be encountered in the rock mass surrounding the potential geological repository at Yucca Mountain. These processes are monitored by a multitude of sensors to measure the temperature, humidity, gas pressure, and mechanical displacement, of the rock formation in response to the heat generated by the heaters. In addition to collecting passive monitoring data, active hydrological and geophysical testing is also being carried out periodically in the DST. These active tests are intended to monitor changes in the moisture redistribution in the rock mass, to collect water and gas samples for chemical and isotopic analysis, and to detect microfiacturing due to heating. On December 3, 1998, the heaters in the DST were activated. The planned heating phase of the DST is 4 years, and the cooling phase following the power shutoff will be of similar duration. The present report summarizes interpretation and analysis of thermal, hydrological, chemical, and geophysical data for the first 6 months; it is the first of many progress reports to be prepared during the DST.

Successful GPR profiling of the subsurface media to delineate the distribution of permafrost, water-table, and bedrock depths is critical for successful ground-water flow modeling in cold-regions environments. This work develops a coupled processing system capable of handling GPR data characterized by a high degree of uncertainty and geophysical ambiguities. Neural network modules were designed to accomplish two main processing goals: 1) recognizing the "subsurface pattern" and 2) estimating depths of subsurface layers like permafrost, ground-water table, and bedrock. A preprocessing procedure transformed raw GPR data into a small-feature vector containing the most representative and discriminative features of the signal which were used as inputs for the neural network. An independent, consecutive-layer identification system processed the same extracted features into depth and dielectric constant information to identify the stratified layers sequentially. The two strategies are complementary. Using both in a coupled system increased the confidence of either system alone. The developed and trained system is fast enough for real-time, field-operations in conjunction with industrial GPR equipment.

SEGEP has more than doubled Southeast Geysers injection rates, significantly mitigating steam production decline. Injection-induced seismicity was observed both before and after the SEGEP startup. For MEQ's of magnitude (M)2.0 there was no discernable change in activity, with about 4 events per year recorded both before and after SEGEP. The largest events recorded, M = 2.6 and 2.4, occurred over a year prior to SEGEP. The absence of a correlation in the M> or =2.0 range is consistent with previous analyses of injection-induced seismicity both at The Geysers and at Larderello field, Italy. These observations suggest a magnitude ceiling for injection-induced seismicity at both steamfields.

During the early years of operation, all waste brines were sent to an evaporation pond built west of the production area. In 1989, cooled pond brines began to be successfully injected into the reservoir along the western boundary of the geothermal system. The injection rate varied over the years; being at present around 20% of the total fluid extracted. As expected under the continental desert conditions prevailing in the area, the temperature and salinity of the pond brines change with the seasons, being higher during the summer and lower during the winter. The chemistry of pond brines is also affected by precipitation of silica, oxidation of H (sub 2) S and reaction with airborne clays. Several production wells in the western part of the field (CP-I area) showed beneficial effects from injection. The chemical (chloride, isotopic) and physical (enthalpy, flow rate) changes observed in producers close to the injectors are reviewed. Some wells showed steam flow increases, in others steam flow decline rates flattened. Because of their higher density, injected brines migrated downward in the reservoir and showed up in deep wells.

These projects will reduce greenhouse gas (GHG) emissions or sequester carbon, and will also result in non-GHG benefits (i.e., environmental, economic, and social benefits). Monitoring, evaluating, reporting, and verifying (MERV) guidelines are needed for these projects to accurately determine their net GHG, and other, benefits. Implementation of MERV guidelines is also intended to: (1) increase the reliability of data for estimating GHG benefits; (2) provide real-time data so that mid-course corrections can be made; (3) introduce consistency and transparency across project types and reporters; and (4) enhance the credibility of the projects with stakeholders. In this paper, we review the issues involved in MERV activities. We identify several topics that future protocols and guidelines need to address, such as: (1) establishing a credible baseline; (2) accounting for impacts outside project boundaries through leakage; (3) net GHG reductions and other benefits; (4) precision of measurement; (5) MERV frequency and the persistence (sustainability) of savings, emissions reduction, and carbon sequestration; (6) reporting by multiple project participants; (7) verification of GHG reduction credits; (8) uncertainty and risk; (9) institutional capacity in conducting MERV; and (10) the cost of MERV.

Mixing ventilation or rather displacement ventilation? AN - 17313394; 4594658 AB - Experimental investigations and practical experiences in Europe have proved that hydronic cooled ceilings are able to remove high cooling loads without impairing thermal comfort. As hydronic cooled ceilings cannot remove latent loads and pollutants, e.g., CO sub(2), VOCs, odors, additional ventilation has to be applied. Often, displacement ventilation is used, which is able to provide lower pollutant levels in the occupation zone than mixing flow systems, if the occupants are causing most of the pollution. Unfortunately, the advantage of the displacement flow, in respect to the air quality, can vanish when cooled ceilings are used to remove the major part of the sensible cooling load. For these applications, a combination of a cooled ceiling with a mixing ventilation system might be more appropriate. This paper presents the results of an investigation examining the distribution of tracer gas in a test chamber which is equipped with a radiant cooled ceiling. There is both a displacement flow system and a mixing flow system available, so that the concentrations of the tracer gas within the occupation zone characterizing the air quality can be compared directly and evaluated under similar conditions. The vertical air temperature rise is taken into consideration as well, as it influences the displacement flow and is an important issue for assessing thermal comfort. The results show the interaction of the portion of the cooling load being removed by the supply air, the air quality in the occupied zone and the vertical air temperature rise. The figures and tables presented show which of the two supply air systems investigated have advantages over the other.

It is well suited to deal with complex real-world thermo-hydro-geochemical problems for singlephase variably water saturated porous media flow systems. The model considers a wide range of hydrological and thermodynamic as well as chemical processes such as aqueous complexation, acid-base, redox, mineral dissolution/precipitation, gas dissolution/ex-solution, ion exchange and adsorption via surface complexation. Under unsaturated conditions only water flow is considered, although gas pressures are allowed to vary in space in a depth-dependent manner specified by the user. In addition to the fully iterative sequential approach (SIA), a sequential non-iterative approach (SNIA), in which transport and chemistry are de-coupled, was implemented and tested. The accuracy and numerical performance of SIA and SNIA have been compared using several test cases. The accuracy of SNIA depends on space and time discretization as well as on the nature of the chemical reactions. The capability of the code to model a real case study in the field is illustrated by its application to the modeling of the hydrochemical evolution of the Llobregat Delta aquitard in northeastern Spain over the last 3500 years during when fresh-water flow from a lower aquifer displaced the native saline aquitard waters. Manzano and Custodio carried out a reactive transport model of this case study by using the PHREEQM code and considering water flow, aqueous complexation, cation exchange and calcite dissolution. Their results compare favorably well with measured porewater chemical data, except for some of the cations. Our code is not only able to reproduce the results of previous numerical models, but leads to computed concentrations which are closer to measured data mainly because our model takes into consideration redox processes in addition to the processes mentioned above. A number of sensitivity runs were performed with TRANQUI in order to analyze the effect of errors and uncertainties on cation selectivities.

The recently completed Escherichia coli genome sequence revealed that the largest family of paralogous E. coli proteins is composed of ABC transporters. Many eukaryotic proteins of medical significance belong to this family, such as the cystic fibrosis transmembrane conductance regulator (CFTR), the P-glycoprotein (or multidrug-resistance protein) and the heterodimeric transporter associated with antigen processing. Here we report the crystal structure at 1.5 angstrom resolution of HisP, the ATP-binding subunit of the histidine permease, which is an ABC transporter from Salmonella typhimurium. We correlate the details of this structure with the biochemical, genetic and biophysical properties of the wild-type and several mutant HisP proteins. The structure provides a basis for understanding properties of ABC transporters and of defective CFTR proteins.

AN - 70102804; 9837917 AB - Previous experiments on DNA sequence context reported that base modification, replication, and repair are affected by the nature of neighbor bases. We now report that repair by mammalian alkylpurine-DNA-N-glycosylases (APNG) of 15-mer oligonucleotides with a central 1,N6-ethenoadenine (epsilonA), flanked by 5' and 3' tandem bases, is also highly sequence dependent. Oligonucleotides with the central sequences -GGepsilonAGG- or -CCepsilonACC- are repaired 3-5-fold more efficiently than those containing -AAepsilonAAA- or -TTepsilonATT- when using human or mouse APNG. Melting curves of the same duplexes showed that oligomers with G.C/C. G neighbors were less denatured than those with A.T/T.A neighbors at 37 degreesC. This sequence-dependent difference in denaturation correlates with the relative thermodynamic stability of oligomers with G.C/C.G or A.T/T.A neighbors. The dependence of repair on thermal stability was confirmed by enzyme reactions performed over 0-45 degreesC. Under these conditions, repair of epsilonA flanked by G.C/C.G was dramatically increased at 37 degreesC with continuous increase up to 45 degreesC, in contrast to that with flanking A.T/T. A pairs, which was in agreement with the degree of denaturation of these duplexes. These results indicate that the thermodynamic stability conferred by base pairs flanking epsilonA plays an essential role in maintaining the integrity of the duplex structure which is necessary for repair.

AN - 79632064; 11725795 AB - Neutron fluences were measured from 435 MeV/nucleon Nb ions stopping in a Nb target and 272 MeV/nucleon Nb ions stopping in targets of Nb and Al for neutrons above 20 MeV and at laboratory angles between 3 degrees and 80 degrees. The resultant spectra were integrated over angles to produce neutron energy distributions and over energy to produce neutron angular distributions. The total neutron yields for each system were obtained by integrating over the angular distributions. The angular distributions from all three systems are peaked forward, and the energy distributions from all three systems show an appreciable yield of neutrons with velocities greater than the beam velocity. Comparison of the total neutron yields from the two Nb + Nb systems suggests that the average neutron multiplicity decreases with decreasing projectile energy. Comparison of the total yields from the two 272 MeV/nucleon systems suggests that the total yields show the same dependence on projectile and target mass number as do total inclusive neutron cross sections. The data are compared with Boltzmann-Uehling-Uhlenbeck model calculations. JF - Physical review.

Understanding key driving forces in the energy end-use sectors provides insights for development of projections of future greenhouse gas emissions. This paper examines global and regional historical trends in energy use and carbon emissions in the industrial, buildings, transport, and agriculture sectors. Activity and economic drivers as well as trends in energy and carbon intensity are evaluated. We show that macro-economic indicators, such as GDP, are insufficient for comprehending trends and driving forces at the sectoral level. These indicators need to be supplemented with sector-specific information for a more complete understanding of future energy use and greenhouse gas emissions.

AN - 70088001; 9840181 AB - DNA double-strand breaks (DSBs) were measured within a 3.2-Mbp NotI fragment on chromosome 21 of cells of a normal human fibroblast cell line. Correct rejoining of DSBs was followed by measuring reconstitution of the original-size NotI fragment, and this was compared to total rejoining as measured by a conventional pulsed-field gel electrophoresis technique (FAR assay). After 80 Gy of particle irradiations with LETs in the range of 7-150 keV/microm, it was found that the repair kinetics was generally slower after irradiation with high-LET particles compared to X irradiation and that a larger proportion of the breaks remained unrepaired after 24 h. On the other hand, the misrejoining frequency as measured by the difference between correct and total rejoining after 24 h did not change with LET, but was approximately the same for all radiations at this dose, equal to 25-30% of the initial breaks. This result is discussed in relation to formation of chromosomal aberrations, deletion mutations and other biological end points.

At the potential high-level nuclear waste repository at Yucca Mountain, water flowing in fast pathways may ultimately contact waste packages and transport radionuclides to the accessible environment. Sixteen experiments were conducted to visualize heat-driven liquid flow in fracture models that included (1) assemblies of roughened glass plates, (2) epoxy replicas of rock fractures, and (3) a fractured specimen of Topopah Spring tuff. Continuous rivulet flow was observed for high liquid flow rates, intermittent rivulet flow and drop flow for intermediate flow rates, and film flow for lower flow rates and wide apertures. Heat pipe conditions (vapor-liquid counterflow with phase change) were identified in five of the seven experiments in which spatially resolved thermal monitoring was performed but not when vapor-liquid counterflow was hindered by very narrow apertures and when an inadequate working fluid volume was used.

The irrigation-induced selenium toxicity discovered at Kesterson changed public perception of agriculture as a benign consumer of water, eroded the political power of the agricultural lobby, and has contributed to a revision in the allocation of water between the cities, agriculture and the environment. The Mono Lake Decisions of 1983 and 1994 set an equally important precedent in affirming the State's public trust obligation to preserve public resources and to reconsider previous water right allocations in the light of evolving knowledge and changing priorities. Both of these issues were important precursors for the current multi-billion dollar State and Federal (CALFED) initiative to 'fix' the myriad of biologic, hydrologic and water quality problems of the San Francisco Bay estuary. In this paper, we compare the Kesterson and Mono Lake controversies and discuss the role of science and research in attempting to resolve these issues. We conclude by drawing linkages to the current CALFED initiative and suggesting implications for future water quality management in California's lakes and reservoirs.

Predicted salt loads from the water quality forecasting model, SJRIODAY, were consistently within plus or minus 11 percent of actual, within plus or minus 14 percent for seven-day forecasts, and within plus or minus 26 percent for 14-day forecasts for the 16-month trial period. When the 48 days dominated by rainfall/runoff events were eliminated from the data set, the error bar decreased to plus or minus 9 percent for the model and plus or minus 11 percent and plus or minus 17 percent for the seven-day and 14-day forecasts, respectively. Constraints on the use of the model for salinity management on the San Joaquin River include the number of entities that control or influence water quality and the lack of a centralized authority to direct their activities. The lack of real-time monitoring sensors for other primary constituents of concern, such as selenium and boron, limits the application of the model to salinity at the present time. A case study describes wetland drainage releases scheduled to coincide with high river flows and significant river assimilative capacity for salt loads.

The amount and location of simulated monthly precipitation agrees well with observations. Soil water content variation was closely correlated with precipitation. Land-surface evaporation and the surface energy budget were strongly controlled by soil moisture content. A sensitivity test with reduced initial soil moisture content suggested that near-surface soil moisture spins up quickly after heavy precipitation events. However, variations in the initial soil moisture field may alter details of the simulated precipitation which can introduce further complexity in climate simulations.

Furthermore, many biological studies would be aided by the ability to assemble biomolecules under physiological conditions. These challenges have motivated the development of chemoselective ligation, the selective covalent coupling of mutually and uniquely reactive functional groups under mild, aqueous conditions. This technique has attracted significant attention recently for the synthesis of biological macromolecules of defined homogeneous composition, the design of self-assembling drugs and the chemical remodeling of cell surfaces.

AN - 70038603; 9811839 AB - Etheno adducts in DNA arise from multiple endogenous and exogenous sources. Of these adducts we have reported that, 1,N6-ethenoadenine (epsilonA) and 3,N4-ethenocytosine (epsilonC) are removed from DNA by two separate DNA glycosylases. We later confirmed these results by using a gene knockout mouse lacking alkylpurine-DNA-N-glycosylase, which excises epsilonA. The present work is directed toward identifying and purifying the human glycosylase activity releasing epsilonC. HeLa cells were subjected to multiple steps of column chromatography, including two epsilonC-DNA affinity columns, which resulted in >1,000-fold purification. Isolation and renaturation of the protein from SDS/polyacrylamide gel showed that the epsilonC activity resides in a 55-kDa polypeptide. This apparent molecular mass is approximately the same as reported for the human G/T mismatch thymine-DNA glycosylase. This latter activity copurified to the final column step and was present in the isolated protein band having epsilonC-DNA glycosylase activity. In addition, oligonucleotides containing epsilonC.G or G/T(U), could compete for epsilonC protein binding, further indicating that the epsilonC-DNA glycosylase is specific for both types of substrates in recognition.

AN - 70028774; 9806616 AB - Shortly after the discovery of polonium and radium by Marie Curie and her husband and colleague, Pierre Curie, it was learned that exposure to these alpha-particle emitters produced deleterious biological effects. The mechanisms underlying the increased biological effectiveness of densely ionizing radiations, including alpha particles, neutrons and highly energetic heavy charged particles, remain an active area of investigation. In this paper, we review recent advances in several areas of the radiobiology of these densely ionizing radiations, also known as heavy ions. Advances are described in the areas of DNA damage and repair, chromosome aberrations, mutagenesis, neoplastic transformation in vitro, genomic instability, normal tissue radiobiology and carcinogenesis in vivo. We focus on technical innovations, including novel applications of pulsed-field gel electrophoresis, fluorescence in situ hybridization (FISH), linkage analysis, and studies of gene expression and protein expression. We also highlight the use of new cellular and animal systems, including those with defined DNA repair deficiencies, as well as epithelial cell model systems to assess neoplastic transformation both in vitro and in vivo. The studies reviewed herein have had a substantial impact on our understanding of the genotoxic effects of heavy ions as well as their distinct effects on tissue homeostasis. The use of these radiations in cancer therapy is also discussed. The use of both heavy-ion and proton therapy is on the upswing in several centers around the world, due to their unique energy deposition characteristics that enhance the therapeutic effect and help reduce damage to normal tissue.

FTIR and Raman spectroscopic studies indicate that the reactive OH and H (sub 2) O sites linked to Ca/Al atoms cannot be distinguished unambiguously because of the strong overlap in the OH stretching region. Two of the three SO (super 2-) (sub 4) polyhedra exhibit weaker H-bonding with structural water, and have the S-O symmetric stretch at a higher wave number than that of aqueous solutions. Arsenate sorption in ettringite caused changes in ettringite OH/H (sub 2) O and SO (super 2-) (sub 4) vibrations which varied as a function of solid phase AsO (super 3-) (sub 4) concentration, mode of sorption and pH. It is suggested that AsO (super 3-) (sub 4) forms inner-sphere complexes in all adsorption samples. The coprecipitated samples show similar AsO (super 3-) (sub 4) bonding to the adsorption samples at high sorption densities.

These parameters are usually inferred by minimizing the sum of the squared differences between the observed system state and the one calculated by a mathematical model. The robustness of the least squares criterion, however, has to be questioned because of the tendency of outliers in the measurements to strongly influence the outcome of the inversion. We have examined alternative approaches to the standard least squares formulation. The robustness of these estimators has been tested by means of Monte Carlo simulations of a synthetic experiment, in which both non-Gaussian random errors and systematic modeling errors have been introduced. The approach was then applied to data from an actual gas-pressure-pulse-decay experiment. The study demonstrates that robust estimators have the potential to reduce estimation bias in the presence of noisy data and minor systematic errors, which may be a significant advantage over the standard least squares method.

AN - 73974540; 9753738 AB - An RNA 'kissing' complex is formed by the association of two hairpins via base pairing of their complementary loops. This sense-antisense RNA motif is used in the regulation of many cellular processes, including Escherichia coli ColE1 plasmid copy number. The RNA one modulator protein (Rom) acts as a co-regulator of ColE1 plasmid copy number by binding to the kissing hairpins and stabilizing their interaction. We have used heteronuclear two-dimensional NMR spectroscopy to map the interface between Rom and a kissing complex formed by the loop of the trans -activation response (Tar) element of immunodeficiency virus 1 (HIV-1) and its complement. The protein binding interface was obtained from changes in amide proton signals of uniformly 15N-labeled Rom with increasing concentrations of unlabeled Tar-Tar*. Similarly, the RNA-binding interface was obtained from changes in imino proton signals of uniformly 15N-labeled Tar with increasing concentrations of unlabeled Rom. Our results are in agreement with previous mutagenesis studies and provide additional information on Rom residues involved in RNA binding.

As-O vibrations of metal AsO (super 3-) (sub 4) complexes are listed from this work, for haidingerite, pharmacolite, sainfeldite, berzelite, scorodite, erythrite and annabergite. The IR and Raman spectra indicate that the AsO (super 3-) (sub 4) geometry is strongly distorted by protonation, and the relative effects of the AsO (super 3-) (sub 4) polyhedra decrease in the order H (super +) >> cation > or = H (sub 2) O, this trend being valid for several metal arsenates. Metal complexation of protonated arsenate does not significantly change the group frequencies of that arsenate polyhedra. Theoretical vibrational spectra of simple AsO (super 3-) (sub 4) -proton and -metal clusters are calculated and together with experimental results on structurally known AsO (super 3-) (sub 4) models, provide a working hypothesis for the interpretation of spectral information in the AsO (super 3-) (sub 4) systems. AsO (super 3-) (sub 4) coordination is difficult to identify when it is protonated, but its coordination on substrate surfaces can bei interpreted accurately using IR and Raman spectroscopy when it is not protonated.

To quantify these processes as accurately as possible is a theoretically challenging and practically important issue. In this study, we propose a new formulation for modeling flow and transport in unsaturated fractured rocks. The formulation is mainly based on a hypothesis that only a portion of connected fractures are active in conducting water. Analysis of the relevant data with the new formulation suggests that about 18-27% of the connected fractures in the Topopah Spring welded (TSw) unit (the potential repository unit) of Yucca Mountain are active under ambient conditions. The relatively high percentage of active fractures is consistent with field observations from a variety of sources. Sensitivity analyses are performed to investigate effects of the "activity" of connected fractures on flow and transport behavior in unsaturated rocks.

Use of the federally owned San Luis Drain was made contingent on the formation of a regional drainage management authority by the project proponents and compliance with strict monthly and annual selenium-load targets and agreement to strict monthly and annual selenium-load targets for discharges from the 97,000-acre (44,000 hectares) project area. During the first year of this 5-year project, the Grasslands Basin farmers were successful in reducing selenium export from the project area by 44% and 33% when compared to water years 1995 and 1996. Although monthly targets were exceeded during the spring months of 1997, in part due to unusually high rainfall runoff from the project area and upper watershed, the goals of the project were met. There is popular sentiment that more was learned about selenium drainage management and achieved in selenium load reductions by participating water districts during the first year of the project than in the past decade.

The results verify that the storage is related to the fracture opening, which is dependent on the combined stiffness of the fracture and the ambient rock mass. In most practical cases the storage is entirely controlled by the normal stiffness of the fractures. The strong coupling to the fracture opening implies that the storage capacity can be estimated from the pressure dependency of the fracture aperture in a high-pressure injection test. Such high-pressure injection tests can be conducted in addition to a conventional low-pressure test to independently determine the storativity of the fracture. This provides an additional validation of the evaluated storativity, which implies not only that the value is more accurately assessed but also that other hydraulic properties can be determined more unambiguously. The method of high-pressure injection testing is applied in field experiments to deep fractures in granitic rocks at two sites, and its usefulness is demonstrated in an analysis of the field data.

The crystal structure of the entire 1,285 amino acid di-chain neurotoxin was determined at 3.3 Angstrom resolution. The structure reveals that the translocation domain contains a central pair of alpha helices 105 Angstrom long and a similar to 50 residue loop or belt that wraps around the catalytic domain. This belt partially occludes a large channel leading to a buried, negative active site -- a feature that calls for radically different inhibitor design strategies from those currently used. The fold of the translocation domain suggests a mechanism of pore formation different from other toxins. Lastly, the toxin appears as a hybrid of varied structural motifs and suggests a modular assembly of functional subunits to yield pathogenesis.

Fab-10 complexes have been determined for wild-type (WT) and epitope-mutated lysozymes by a homogeneous solution method based on the 95% reduced enzymatic activity of the complex. The values fall within a narrow 10-fold range [(0.18 to 1.92) x 10(6) M(-1)s(-l)]. The affinity constants, K(D), cover a broader, 440-fold, range from 0.075 to 33 nM. Values of K(D) as high as 7 microM were obtained for the complexes prepared from some mutations at HEWL positions 96 and 97, but the associated kinetic constants could not be determined. The values of k(on) are negatively correlated with side-chain volume at position 101HEWL, but are essentially independent of this parameter for position 21HEWL substitutions. The multiple mutations made at positions 21HEWL and 101HEWL provide sufficient experimental data on complex formation to evaluate phi values [phi = (deltadeltaGon)/(deltadeltaG(D))] at these two positions to begin to define trajectories for protein-protein association. The data, when interpreted within the concept of a two-step association sequence embracing a metastable encounter complex intermediate, argue that the rate determining step at position 21HEWL (phiavg = 0.2) is encounter complex formation, but the larger phi(avg) value of 0.36 experienced for most position 101HEWL mutations indicates a larger contribution from the post-encounter annealing process at this site for these replacements.

This hypothesis was tested by validating and demonstrating the use of SEIRA with a metal-overlayer configuration to identify qualitatively on vesicular basalt surfaces the highly localized differences in the chemical composition and in the structure of clusters of endolithic bacteria, vesicles, and minerals. The metal-overlayer configuration was achieved by evaporating a thin gold-film on basalt specimen surfaces. Fourier-transform SEIRA microspectra of the specimen surfaces were recorded in the 650-4000 cm super(-1) infrared region at a resolution of 4 cm super(-1) on a Fourier-transform infrared spectrometer coupled to an infrared microscope. All bacteria-inhabiting surfaces exhibited infrared absorption bands indicative of bacterial cells, bands that became ideal biomarkers by which to detect the presence of bacteria. All basalt surfaces exhibited infrared absorption bands indicative of silicates, bands that became ideal mineral markers by which to detect the presence of silicate-containing minerals and locations of vesicles (gas-bubble cavities). Comparative analysis of space-resolved microspectra suggested that bacteria in the vesicular basalt lived not only on the vesicle surface but that they also penetrated and lived beneath the vesicle surface. The penetration terminated when calcicplagioclase feldspar became the dominant constituent mineral in the vesicular basalt.

Two pathways are considered. In the direct pathway, a reduction in cooling energy use translates into reduced demand for generation capacity and, thus, reduced precursor emissions from electric utility power plants. In the indirect pathway, reduced air temperatures can slow the atmospheric production of ozone as well as precursor emission from anthropogenic and biogenic sources. The simulations suggest small impacts on emissions following implementation of cool communities in the SoCAB. In summer, for example, there can be reductions of up to 3% in NO sub(x) emissions from in-basin power plants. The photochemical simulations suggest that the air quality impacts of these direct emission reductions are small. However, the indirect atmospheric effects of cool communities can be significant. For example, ozone peak concentrations can decrease by up to 11% in summer and population-weighted exceedance exposure to ozone above the California and National Ambient Air Quality Standards can decrease by up to 11 and 17%, respectively. The modeling suggests that if these strategies are combined with others, such as mobile-source emission control, the improvements in ozone air quality can be substantial.

We characterize light-induced changes in protein conformation by electron diffraction difference Fourier maps, and relate these to previous work on photocycle intermediates by infrared (FTIR) spectroscopy. Samples illuminated at 170K are confirmed by FTIR spectroscopy to be in the L state; a difference Fourier projection map shows no structural change within the 0.35-nm resolution limit of our data. Difference maps obtained with samples illuminated at 220K, 230K, and 240K, respectively, reveal a progressively larger structural response in helix F when the protein is still in the M state, as judged by the FTIR spectra. Consistent with previous structural studies, an adjustment in the position or in the degree of ordering of helix G accompanies this motion. The model of the photocycle emerging from this and previous studies is that bacteriorhodopsin experiences minimal change in protein structure until a proton is transferred from the Schiff base to Asp super(85). The M intermediate then undergoes a conformational evolution that opens a hydrated "half-channel," allowing the subsequent reprotonation of the Schiff base by Asp super(96).

The objective functions involved are often topographically complex and may contain many local minima. Because of these reasons, the inverse solutions are commonly very sensitive to the initial guess of the parameters when conventional optimizers are used. This paper presents an annealing-simplex method that incorporates simulated annealing strategies into a classical downhill simplex method. An upward infiltration experiment was used as an example of inverse estimation to test the method. Numerical experiments of both minimizing an algebraic function and inversion of upward infiltration data showed that the new method successfully converged to the global minimum in all cases, irrespective of the initial hydraulic parameter estimates, while the classical downhill method often converged to unfavorable local minima. The CPU times needed for the annealing-simplex method to estimate 5 and 7 hydraulic parameters simultaneously are about a half hour and 1 hour on a PC, respectively. Additionally, no special requirements are imposed on the objective function, and the method is independent of the details of the simulation submodel. Therefore the proposed method should be applicable to other optimization problems in water resources when it is important to have a robust global search capability.

The Hopland watershed of the Russian River in the northern California Coastal Range and the headwater of the North Fork American River in the northern Sierra Nevada were selected to investigate the hydroclimate, snow budget, and streamflow at different elevations. Simulated precipitation and streamflow at the Hopland basin closely approximated observed values. An intercomparison between the semidistributed TOPMODEL and two versions of the lumped Sacramento model for the severe storm event of January 1995 indicates that both types of models predicted a similar response of river outflows from this basin, with the exception that TOPMODEL predicted a faster recession of river flow with less base flow after precipitation ended. Precipitation in this low-elevation watershed was predominantly in the form of rain, causing a fast streamflow response. The high-elevation Sierra Nevada watershed received most of its precipitation as snowfall. As a result, the frozen water held in surface storage delayed runoff and streamflow. Application of a simple elevation-dependent snowfall and rainfall partitioning scheme showed the significance of finescale terrain variation in the surface hydrology at high-elevation watersheds.

The protein is closely associated with cell proliferation in the G sub(1)-S stage of the cell cycle. Recent findings show that the eIF-5A proteins are highly expressed in tumor cells and act as a cofactor of the Rev protein in HIV-1-infected cells. The mature eIF is the only protein known to have the unusual amino acid hypusine, a post-translationally modified lysine. The crystal structure of eIF-5A from Methanococcus jannaschii (MJ eIF-5A) has been determined at 1.9 Aa and 1.8 Aa resolution in two crystal forms by using the multiple isomorphous replacement method and the multiwavelength anomalous diffraction method for the first crystal form and the molecular replacement method for the second crystal form. The structure consists of two folding domains, one of which is similar to the oligonucleotide-binding domain found in the prokaryotic cold shock protein and the translation initiation factor IF1 despite the absence of any significant sequence similarities. The 12 highly conserved amino acid residues found among eIF-5As include the hypusine site and form a long protruding loop at one end of the elongated molecule.

The sHSPs can form large multimeric structures and have a wide range of cellular functions, including endowing cells with thermotolerance in vivo and being able to act as molecular chaperones in vitro; sHSPs do this by forming stable complexes with folding intermediates of their protein substrates. However, there is little information available about these structures or the mechanism by which substrates are protected from thermal denaturation by sHSPs. Here we report the crystal structure of a small heat-shock protein from Methanococcus jannaschii, a hyperthermophilic archaeon. The monomeric folding unit is a composite beta -sandwich in which one of the beta -strands comes from a neighbouring molecule. Twenty-four monomers form a hollow spherical complex of octahedral symmetry, with eight trigonal and six square "windows". The sphere has an outer diameter of 120 angstroms and an inner diameter of 65 angstroms. JF - Nature AU - Kim, Kyeong Kyu AU - Kim, R AU - Kim, Sung-Hou AD - Phys. Biosci.

A sHSP homologue of Methanococcus jannaschii, a hyperthermophilic Archaeon, forms a homogeneous multimer comprised of 24 monomers with a molecular mass of 400 kDa in contrast to other sHSPs that show heterogeneous oligomeric complexes. Electron microscopy analysis revealed a spherically shaped oligomeric structure ~15-20 nm in diameter. The protein confers thermal protection of other proteins in vitro as found in other sHSPs. Escherichia coli cell extracts containing the protein were protected from heat- denatured precipitation when heated up to 100 degree C, whereas extracts from cells not expressing the protein were heat-sensitive at 60 degree C. Similar results were obtained when purified sHSP protein was added to an E. coli cell lysate. The protein also prevented the aggregation of two purified proteins: single-chain monellin (SCM) at 80 degree C and citrate synthase at 40 degree C.

AN - 80013961; 9671489 AB - Chromatin assembly factor I (CAF-I) is a three-subunit histone-binding complex conserved from the yeast Saccharomyces cerevisiae to humans. Yeast cells lacking CAF-I (cacDelta mutants) have defects in heterochromatic gene silencing. In this study, we showed that deletion of HIR genes, which regulate histone gene expression, synergistically reduced gene silencing at telomeres and at the HM loci in cacDelta mutants, although hirDelta mutants had no silencing defects when CAF-I was intact. Therefore, Hir proteins are required for an alternative silencing pathway that becomes important in the absence of CAF-I. Because Hir proteins regulate expression of histone genes, we tested the effects of histone gene deletion and overexpression on telomeric silencing and found that alterations in histone H3 and H4 levels or in core histone stoichiometry reduced silencing in cacDelta mutants but not in wild-type cells. We therefore propose that Hir proteins contribute to silencing indirectly via regulation of histone synthesis. However, deletion of combinations of CAC and HIR genes also affected the growth rate and in some cases caused partial temperature sensitivity, suggesting that global aspects of chromosome function may be affected by the loss of members of both gene families.

Last updated - 2017-02-22 ER - TY - JOUR T1 - Differential cleavage of oligonucleotides containing the benzene-derived adduct, 1,N6-benzetheno-dA, by the major human AP endonuclease HAP1 and Escherichia coli exonuclease III and endonuclease IV. AN - 73929195; 9744526 AB - We report here that the newly synthesized DNA adduct, 1,N6-benzetheno-dA (pBQ-dA), in defined oligonucleotides [Chenna and Singer, Chem. Res. Toxicol., 8, 865-874], is a substrate for the major human AP endonuclease, HAP1, and the Escherichia coli AP endonucleases, exonuclease III and endonuclease IV. The mechanism of cleavage is identical to that reported previously for 3,N4-benzetheno-dC (pBQ-dC) and leads to a phosphodiester bond cleavage 5' to the adduct. There are, however, significant differences in the rate of cleavage of this adduct by these enzymes. The two bacterial AP endonucleases are both much more efficient than the human repair enzyme. In addition, using two random oligodeoxynucleotide sequences containing a single pBQ-dA, exonuclease III and endonuclease IV are similarly active, while HAP1 shows a distinct sequence preference of approximately 10-fold in efficiency of cleavage. The repair of this adduct by the three recombinant enzymes is further confirmed by using both active site mutant HAP1 proteins and by E.coli mutant strains lacking exonuclease III and/ or endonuclease IV. This sequence-dependent repair of pBQ-dA by HAP1 may play an important role in modulating benzene-induced carcinogenesis.

S. civilian nuclear waste program is unique in its focus on disposal of high-level wastes in the unsaturated zone (UZ), above the water table. The potential repository site currently under investigation is located in a semi-arid region of the southwestern U. S. at Yucca Mountain, Nevada. The geology of the site consists of layered sequences of faulted, fractured, and bedded tuffs. The groundwater table is approximately 600 m beneath the land surface, while the proposed repository horizon is at a nominal depth of approximately 375 m. In this kind of environment, two-phase flow is not just a localized perturbation to natural conditions, as in the saturated zone, but is the predominant mode of water and gas flow. The purpose of this report is to review the current understanding of gas and water flow, and mass transport, in the unique hydrogeologic environment of Yucca Mountain. Characteristics of the Yucca Mountain site are examined, and concepts and mathematical modeling approaches are described for variably saturated flow in thick unsaturated zones of fractured rock. The paper includes a brief summary of the disposal concept and repository design, as developed by a team of engineering contractors to the U. S. Department of Energy (DOE), with strong participation from the DOE National Laboratories.

T2SOLV includes all the Preconditioned Conjugate Gradient (PCG) solvers used in T2CG1, the current solver package, as well as LUBAND, a new direct solver and DLUSTB, a PCG solver based which implements the BiCGSTAB(m) method. LUBAND, the new direct solver, is faster, more reliable and capable of solving problems orders of magnitude larger than the MA28 routine which it replaces. A significant capability of T2VOC is two types of matrix preprocessing, which make possible the solution of a class of challenging numerical problems (previously tractable only with direct solvers) using the PCG routines. For regular grids, the size of problems tractable with direct solvers is doubled by implementing a D4 alternative diagonal gridblock ordering option.

Because changes in K sub(a) were caused largely by changing amounts of water in the formation and to a small extent by diurnal and seasonal temperature fluctuations, TDR served as a useful indicator of the moisture status in the formation. Our results indicate that wetting and drying were spatially variable within and immediately beyond a 7 x 8 m super(2) pond. Various locations close to the surface responded to fast flow, whereas others showed evidence of poor hydraulic communication with the surface. Data collected during a rainfall event, which occurred a few days after ponding ceased, indicated that this boundary condition evoked a similar hydrologic response to ponding. This effort suggests that TDR is a useful tool for detecting moisture changes in fractured media.

AN - 79980062; 9651245 AB - Mitochondrial cytochrome bc1 complex performs two functions: It is a respiratory multienzyme complex and it recognizes a mitochondrial targeting presequence. Refined crystal structures of the 11-subunit bc1 complex from bovine heart reveal full views of this bifunctional enzyme. The "Rieske" iron-sulfur protein subunit shows significant conformational changes in different crystal forms, suggesting a new electron transport mechanism of the enzyme. The mitochondrial targeting presequence of the "Rieske" protein (subunit 9) is lodged between the two "core" subunits at the matrix side of the complex. These "core" subunits are related to the matrix processing peptidase, and the structure unveils how mitochondrial targeting presequences are recognized. JF - Science (New York, N.Y.)

AN - 80030448; 9679214 AB - Environmental tobacco smoke (ETS) is suspected to be a major source of exposure to many of the compounds identified as toxic air contaminants. However, we lack emission factors for many of the ETS air toxics for the brands of cigarettes which currently dominate the market and therefore cannot adequately estimate contributions of ETS to such exposures. This study provides up-to-date emission factors for selected air toxics and other volatile organic compounds (VOCs) in simulated ETS and uses them in a mass balance model to evaluate the potential contribution of ETS to air toxics in indoor air and, therefore to indoor exposures to air toxics. Emission factors (microgram/cigarette) were determined for 21 VOCs (including two aldehydes), nicotine and particulate matter in a room-sized (20-m3) environmental chamber with stainless-steel walls, operated under static conditions, using diluted sidestream smoke (no exhaled mainstream smoke) to simulate ETS. Experiments were conducted for Kentucky Reference cigarette 1R4F and for each of six commercial cigarette brands with major market shares. The variabilities in the ETS emission factors among brands of cigarettes were relatively small, ranging from 16 to 31% (expressed as the coefficient of variation) among the six brands. The concentrations of most of the VOCs did not change over the 4-hour periods of the experiments. However, concentrations of 3-ethenylpyridine, phenol, o-cresol and m,p-cresol showed consistent decreases over time, indicating removal by means other than the very low air infiltration rate (0.03 h-1), e.g., deposition onto the chamber surfaces. Emission factors for these compounds were calculated to take these losses into account and the rate constants for these losses were estimated. To estimate indoor concentrations and inhalation exposures to 16 VOCs, nicotine and PM-2.5, the average emission factors for the six commercial brands were used in a time-dependent mass-balance model for two scenarios: a typical office building and an average residence. In general, the indoor concentrations of the air toxics from ETS, under conditions selected to be "typical" rather than extreme, are comparable in magnitude to average outdoor concentrations, indicating that ETS can be a significant contributor to the total indoor concentration and the inhalation exposure for these species. At higher smoking rates, exposures to VOCs from ETS could be several times higher than those modeled under more "typical" conditions.

AN - 79972492; 9645664 AB - Chemically, 237Np(V) is as toxic as U(VI), and radiologically, about as toxic as 239Pu. Depending on redox conditions in vivo, 237Np exists as weakly complexing Np(V) (NpO2+) or as Np(IV), which forms complexes as stable as those of Pu(IV). Ten multidentate catecholate (CAM) and hydroxypyridinonate (HOPO) ligands with great affinity for Pu(IV) were compared with CaNa3-DTPA for in vivo chelation of 237Np. Mice were injected intravenously with 237NpO2Cl: those in a kinetic study were killed 1 to 2880 min; in ligand studies, fed mice were injected intraperitoneally with a ligand 5, 60, or 1440 min after 237Np(V) (molar ratio 5.6 to 73), mice fasted for 16 h were gastrically intubated with a ligand 3 min after 237Np(V) (molar ratio 5.6 to 274), and all were killed 24 h after ligand administration; tissues and excreta were radioanalyzed. Rapid plasma clearance and urinary excretion of 237Np(V) resemble U(VI); deposition and early retention in skeleton and liver resemble Pu(IV). The x-ray absorption near edge structure spectroscopy (XANES) spectra of femora of 237Np(V)-injected mice, compared with spectra of Np(V) and Np(IV) from reference solids, showed predominantly Np(IV). Significant in vivo 237Np chelation was obtained with all of the HOPO and CAM ligands injected at molar ratio 22; the HOPO ligands reduced 237Np in skeleton, liver, and other soft tissue, on average, to 72, 25, and 25% of control, respectively, while CaNa3-DTPA was ineffective. Two HOPO ligands injected 60 min after 237Np (molar ratio 5.6) significantly reduced body and liver 237Np, and three HOPO ligands given orally (molar ratio > or = 73) significantly reduced body and liver 237Np, compared with controls. Combined with earlier work, these results indicate that: the dominant neptunium species circulating and excreted in urine is Np(V), while that in bone and liver deposits is Np(IV); Np(V) must be reduced to Np(IV) before it can be stably chelated; efficient decorporation of neptunium requires multidentate ligands that form exceptionally stable actinide(IV) chelates and facilitate Np(V) reduction.

AN - 79623783; 11542637 AB - It has recently been demonstrated experimentally that DNA damage induced by high LET radiation in mammalian cells is non-randomly distributed along the DNA molecule in the form of clusters of various sizes. The sizes of such clusters range from a few base-pairs to at least 200 kilobase-pairs. The high biological efficiency of high LET radiation for induction of relevant biological endpoints is probably a consequence of this clustering, although the exact mechanisms by which the clustering affects the biological outcome is not known. We discuss here results for induction and repair of base damage, single-strand breaks and double-strand breaks for low and high LET radiations. These results are discussed in the context of clustering. Of particular interest is to determine how clustering at different scales affects overall rejoining and fidelity of rejoining of DNA double-strand breaks. However, existing methods for measuring repair of DNA strand breaks are unable to resolve breaks that are close together in a cluster. This causes problems in interpretation of current results from high LET radiation and will require new methods to be developed.

Short- and long-term Ni sorption experiments were carried out (< or = two months). The results show that mixed-cation hydroxide phases occur on gibbsite, pyrophyllite and Na-montmorillonite, forming within minutes. the formation of these phases is apparently effected by the addition of a metal cation, such as Ni, to an environment containing a source of hydrolysed species such as Al(III). Non-specific and/or specific adsorption, dissolution of Al and nucleation of a mixed Ni/Al phase occur at the mineral/liquid interface. The importance of combining time-dependent or kinetics studies with spectroscopy for understanding sorption processes at the solid/liquid interface, is demonstrated.

The gas is released mainly as diffuse emissions from normal-temperature soils, but some gas issues from steam vents or leaves the mountain dissolved in cold groundwater. The rate of gas discharge increased significantly in 1989 following a 6-month period of persistent earthquake swarms and associated strain and ground deformation that has been attributed to dike emplacement beneath the mountain. An increase in the magmatic component of helium discharging in a steam vent on the north side of Mammoth Mountain, which also began in 1989, has persisted until the present time. Anomalous CO (sub 2) discharge from soils first occurred during the winter of 1990 and was followed by observations of several areas of tree kill and/or heavier than normal needlecast the following summer. Subsequent measurements have confirmed that the tree kills are associated with CO (sub 2) concentrations of 30-90% in soil gas and gas flow rates of up to 31,000 g m (super -2) d (super -1) at the soil surface. Each of the tree-kill areas and one area of CO (sub 2) discharge above tree line occurs in close proximity to one or more normal faults, which may provide conduits for gas flow from depth. We estimate that the total diffuse CO (sub 2) flux from the mountain is approximately 520 t/d, and that 30-50 t/d of CO (sub 2) are dissolved in cold groundwater flowing off the flanks of the mountain. Isotopic and chemical analyses of soil and fumarolic gas demonstrate a remarkable homogeneity in composition, suggesting that the CO (sub 2) and associated helium and excess nitrogen may be derived from a common gas reservoir whose source is associated with some combination of magmatic degassing and thermal metamorphism of metasedimentary rocks. Furthermore, N (sub 2) /Ar ratios and nitrogen isotopic values indicate that the Mammoth Mountain gases are derived from sources separate from those that supply gas to the hydrothermal system within the Long Valley caldera. Various data suggest that the Mammoth Mountain gas reservoir is a large, low-temperature cap over an isolated hydrothermal system, that it predates the 1989 intrusion, and that it could remain a source of gas discharge for some time.

Despite numerous studies of the energetics of the cation-P interaction in synthetic host-guest systems, its energetic value in biological systems is less well understood. The measurement of cation-P energies by conventional site-directed mutagenesis is complicated by the absence of naturally occurring positively charged isosteres of neutral amino acids; nonisosteric replacements introduce perturbations that are difficult to quantify or subtract out. Consequently, we have used unnatural amino acid mutagenesis with an isosteric pair of unnatural amino acids to quantify the energetic contribution of an engineered cation-P interaction in the interior of staphylococcal nuclease (SNase) to overall protein stability. A hydrophobic pocket composed of two phenylalanine side chains and one tyrosine side chain is occupied in wild-type (WT) SNase by Val super(74) (Scheme 1). This neutral valine residue was replaced with the cationic residue S-methylmethionine using suppressor tRNA methodology (Scheme 1, B). The neutral isostere of S-methylmethionine, homoleucine, was also incorporated into position 74 for purposes of comparison (Scheme 1, A). The thermodynamic stabilities of the two mutants (which have near wild-type catalytic parameters) as well as the difference in aqueous solvation energies of the S-methylmethionine and homoleucine side chains were measured. An upper limit of 2.6 kcal mol super(-1) was obtained for the energy of the engineered cation-P interaction in SNase, in the absence of significant differences in packing interactions for the two mutant proteins.

AN - 79909025; 9611094 AB - We report beam characterization and dosimetric measurements made using a 56Fe beam extracted from the Brookhaven National Laboratory Alternating Gradient Synchrotron (AGS) with a kinetic energy of 1087 MeV/nucleon. The measurements reveal that the depth-dose distribution of this beam differs significantly from that obtained with a 600 MeV/nucleon iron beam used in several earlier radiobiology experiments at the Lawrence Berkeley National Laboratory's BEVALAC. We present detailed measurements of beam parameters relevant for radiobiology, including track- and dose-averaged linear energy transfer (LET), fragment composition and LET spectra measured behind sample holders used in irradiations of biological samples. We also report measurements of fluence behind three depths (1.94, 4.68 and 9.35 g cm(-2)) of polyethylene targets with the 1087 MeV/nucleon beam, and behind 1.94 g cm(-2) of polyethylene with a 610 MeV/nucleon beam delivered by the AGS. These results are compared to earlier measurements with the 600 MeV/nucleon beam at the BEVALAC.

For this reason the marine MT method traditionally has been used only at periods of 103 to 105 s to probe deep mantle structure; rarely does a sea-floor MT response extend to a 100-s period. To be useful for mapping continental shelf structure at depths relevant to petroleum exploration, however, MT measurements need to be made at periods between 1 and 1000 s. This can be accomplished using ac-coupled sensors, induction coils for the magnetic field, and an electric field amplifier developed for marine controlled-source applications. The electrically quiet sea floor allows the attenuated electric field to be amplified greatly before recording; in deep (1-km) water, motional noise in magnetic field sensors appears not to be a problem. In shallower water, motional noise does degrade the magnetic measurement, but sea-floor magnetic records can be replaced by land recordings, producing an effective sea-surface MT response. Field trials of such equipment in 1-km-deep water produced good-quality MT responses at periods of 3 to 1000 s; in shallower water, responses to a few hertz can be obtained. Using an autonomous sea-floor data logger developed at Scripps Institution of Oceanography, marine surveys of 50 to 100 sites are feasible.

Structure-based sequence alignment shows that common residues localize in the nucleotide-binding site and a region that interacts with the nucleotide of the next tubulin subunit in the protofilament, suggesting that tubulin and FtsZ use similar contacts to form filaments. Surfaces that would make lateral interactions between protofilaments or interact with motor proteins are, however, different. The highly conserved nucleotide-binding sites of tubulin and FtsZ clearly differ from those of EF-Tu and other GTPases, while resembling the nucleotide site of glyceraldehyde-3-phosphate dehydrogenase. Thus, tubulin and FtsZ form a distinct family of GTP-hydrolyzing proteins.

We now know that microorganisms exist in every conceivable place on Earth, even in extreme environments. Temperature may be the only limitation as to where they can and cannot exist and/or function. As more small subunit rDNA sequence information becomes available there is a real need to start turning the information into knowledge that can be applied to better elucidate and understand structure-function relationships within ecosystems, develop new culturing methods, and discover new products and processes. It has been stated on numerous occasions that the 21 super(st) century is the century for biology. Within that context, we must address the real value of microbial diversity.

AN - 79898296; 9606609 AB - Many important issues in carcinogenesis can be addressed using our Carcinogenic Potency Database, which analyzes and standardizes the literature of chronic carcinogenicity tests in laboratory animals. This review is an update and overview of our analyses during the past 15 years, using the current database that includes results of 5152 experiments on 1298 chemicals. We address the following: 1. More than half the 1298 chemicals tested in long-term experiments have been evaluated as carcinogens. We describe this positivity rate for several subsets of the data (including naturally occurring and synthetic chemicals), and we hypothesize and important role in the interpretation of results for increased cell division due to administration of high doses. 2. Methodological issues in the interpretation of animal cancer tests: constraints on the estimation of carcinogenic potency and validity problems associated with using the limited data from bioassays to estimate human risk, reproducibility of results in carcinogenesis bioassays, comparison of lifetable and summary methods of analysis, and summarizing carcinogenic potency when multiple experiments on a chemical are positive. 3. Positivity is compared in bioassays for two closely related species, rats and mice, tested under similar experimental conditions. We assess what information such a comparison can provide about interspecies extrapolation. 4. Rodent carcinogens induce tumors in 35 different target organs. We describe the frequency of chemicals that induce tumors in rats or mice at each target site, and we compare target sites of mutagenic and nonmutagenic rodent carcinogens. 5. A broad perspective on evaluation of possible cancer hazards from rodent carcinogens is given, by ranking 74 human exposures (natural and synthetic) on the HERP indes.

AN - 79826584; 9560318 AB - Previous studies have demonstrated that the adhesion-plaque protein, zyxin, interacts specifically with a 23 kDa protein, called the cysteine-rich protein 1 (CRP1), which has been implicated in myogenesis. Primary sequence analyses have revealed that both zyxin and CRP1 exhibit multiple copies of a structural motif called the LIM domain. LIM domains, which are defined by the consensus CX2CX16-23HX2CX2CX2CX16-23CX2-3(C,H,D), are found in a variety of proteins that are involved in cell growth and differentiation. Recent studies have established that LIM domains are zinc-binding structures that mediate specific protein-protein interactions. For example, in the case of the zyxin-CRP1 interaction, one of zyxin's three LIM domains is necessary and sufficient for binding to CRP1. Because the CRP1 molecule is comprised primarily of two LIM domains, we were interested in the possibility that the binding site for zyxin on CRP1 might also be contained within a single LIM domain. Consistent with the hypothesis that the LIM domains of CRP1 are critical for the protein's zyxin-binding function, zinc-depleted CRP1 displays a reduced zyxin-binding activity. However, domain mapping analyses have revealed that neither of the two individual LIM domains of CRP1 can support a wild-type interaction with zyxin. Collectively, our results suggest that the binding site for zyxin on CRP1 is not contained within a single contiguous sequence of amino acids.

The reason it has come to the forefront of scientific investigation is the recent interest in predicting solute transport in geological media as part of safety assessment of geologic isolation of nuclear or toxic wastes. Solute transport is much more sensitive to medium heterogeneity than is temperature or pressure. In this paper, experimental observations of tracer transport over distances ranging from centimeters to hundreds of meters are reviewed, and theoretical efforts to explain or model these observations are summarized. Processes that may explain some of the experimental observations without the use of flow-channeling models are discussed. The paper concludes with a discussion of the implications of flow channeling on the practical problems related to contaminant transport in geologic systems.

Cytochrome bc sub(1) transfers electrons from ubiquinol to cytochrome c and uses the energy thus released to form an electrochemical gradient across the inner membrane. Our X-ray crystal structures of the complex from chicken, cow and rabbit in both the presence and absence of inhibitors of quinone oxidation, reveal two different locations for the extrinsic domain of one component of the enzyme, an iron-sulphur protein. One location is close enough to the supposed quinol oxidation site to allow reduction of the Fe-S protein by ubiquinol. The other site is close enough to cytochrome c sub(1) to allow oxidation of the Fe-S protein by the cytochrome. As neither location will allow both reactions to proceed at a suitable rate, the reaction mechanism must involve movement of the extrinsic domain of the Fe-S component in order to shuttle electrons from ubiquinol to cytochrome c sub(1). Such a mechanism has not previously been observed in redox protein complexes.

This study demonstrates the application of micro-X-ray absorption near-edge structure (micro-XANES) spectroscopy for obtaining such direct, in-situ, spatially and temporally resolved information for selenium. The experiments determine the fate of soluble Se(VI) ponded over water-saturated oxidizing versus reducing sediments. Scanning micro-XANES analyses showed Se(VI) removal from ponded waters by diffusion into sediments and by conversion to Se(0) in the reducing sediment. Zones of accumulation of insoluble Se(0) ware heterogeneously distributed. These results show that the scale over which volume averaging of chemical species is performed at sediment-water boundaries must be selected carefully and that the spatial resolution offered by micro-XANES is well-suited for these types of investigations.

A thorough understanding of non-Newtonian fluid flow through porous media is of fundamental importance in these engineering applications. Considerable progress has been made in our understanding of single-phase porous flow behavior of non-Newtonian fluids through many quantitative and experimental studies over the past few decades. However, very little research can be found in the literature regarding multi-phase non-Newtonian fluid flow or numerical modeling approaches for such analyses. For non-Newtonian fluid flow through porous media, the governing equations become nonlinear, even under single-phase flow conditions, because effective viscosity for the non-Newtonian fluid is a highly nonlinear function of the shear rate, or the pore velocity. The solution for such problems can in general only be obtained by numerical methods. We have developed a three-dimensional, fully implicit, integral finite difference simulator for single- and multi-phase flow of non-Newtonian fluids in porous/fractured media. The methodology, architecture and numerical scheme of the model are based on a general multi-phase, multi-component fluid and heat flow simulator-TOUGH2. Several rheological models for power-law and Bingham non-Newtonian fluids have been incorporated into the model. In addition, the model predictions on single- and multi-phase flow of the power-law and Bingham fluids have been verified against the analytical solutions available for these problems, and in all the cases the numerical simulations are in good agreement with the analytical solutions. In this presentation, we will discuss the numerical scheme used in the treatment of non-Newtonian properties, and several benchmark problems for model verification. In an effort to demonstrate the three-dimensional modeling capability of the model, a three-dimensional, two-phase flow example is also presented to examine the model results using laboratory and simulation results existing for the three-dimensional problem with Newtonian fluid flow.

AN - 79621997; 10819525 AB - Ionizing radiation is a complete carcinogen, able both to initiate and promote neoplastic progression and is a known carcinogen of human and murine mammary gland. Tissue response to radiation is a composite of genetic damage, cell death and induction of new gene expression patterns. Although DNA damage is believed to initiate carcinogenesis, the contribution of these other aspects of radiation response are beginning to be explored. Our studies demonstrate that radiation elicits rapid and persistent global alterations in the mammary gland microenvironment. We postulate that radiation-induced microenvironments may affect epithelial cells neoplastic transformation by altering their number or susceptibility. Alternatively, radiation induced microenvironments may exert a selective force on initiated cells and/or be conducive to progression. A key impetus for these studies is the possibility that blocking these events could be a strategy to interrupt neoplastic progression.

As a part of a project for studying the biological effect of the p-BQ adducts, we report here on the first biophysical characterization of oligodeoxyribonucleotide duplexes containing a single site-specific p-BQ-C, using thermal denaturation and circular dichroism (CD). We find that the thermal and thermodynamic stabilities of the control duplex are reduced by p-BQ-C. The T sub(m) value decreases by 12.6 degree C at the duplex concentration of 1.5 mu M and the Delta G degree by 10.2 kcal/mol. The latter was determined from the concentration dependence of the T sub(m) values. The destabilization has little dependence on the nature of the opposite base. This reduction is higher than that of the single base mismatches studied (-4.9 to -7.9 kcal/mol) and is close to that observed with an adjacent double mismatch-containing duplex (-11.3 kcal/mol). The overall B-conformation of the duplex with a p-BQ-C is, however, only slightly altered, relative to the parent duplex, as shown by CD spectra. The p-BQ-C-containing duplex has been found recently to be a good substrate for the major human AP endonuclease as compared to an abasic site-containing duplex. We now find that the thermodynamic properties and the localized conformational changes of a p-BQ-C-containing duplex are apparently related to those reported for a duplex containing an abasic site.

Our analysis shows that substantial reductions in future greenhouse gas emissions can be realized through the use of more energy-efficient technologies that save money and reduce pollution at the same time. These carbon reductions can therefore be achieved at negative net cost to society.

This paper presents conceptual and numerical models which aim at developing an understanding of water seepage behavior in such media, and exploring conditions for fast preferential flow. Water seepage has been numerically simulated in heterogeneous fractures, which were conceptualized as two-dimensional heterogeneous porous media. Flow was found to proceed in dendritic patterns along preferential paths, giving rise to such features as localized ponding and bypassing. Fast preferential flow can occur from 'external' (non-uniform boundary conditions) or 'internal' mechanisms (heterogeneities), or a combination thereof. A most effective condition for fast preferential flow is the presence of sub-horizontal barriers of significant length. Limited parameter variation studies have shown strong dependence of seepage patterns on fracture permeability and applied flow rate. The temporal evolution of seeps proceeds on a vast range of time scales. This casts doubt on the applicability of steady-state concepts for water migration in unsaturated zones of fractured rock where infiltration is episodic. An approximate invariance of seepage behavior was derived for simultaneous space-and-time scaling, suggesting that seepage patterns should appear more vertically elongated as the scale of observation is increased. Numerical simulation experiments have confirmed this invariance, as well as its limits of applicability.

Thus, both calculated reaction paths should be theoretically identical whatever the chemical complexity of the water-rock system (i.e., multicomponent, multireaction zones kinetically and equilibrium-controlled). We propose to use this property to numerically test the thermo-kinetic hydrochemical Eulerian codes and we employ it to verify the algorithm of the 1D finite difference code KIRMAT. Compared to the other methods to perform such numerical tests (i.e., comparisons with analytical, semi-analytical solutions, between two Eulerian hydrochemical codes), the advantage of this new method is the absence of constraints on the chemical complexity of the modelled water-rock systems. Moreover, the same thermo-kinetic databases and geochemical functions can be easily and mechanically used in both calculations, when the numerical reference comes from the Eulerian code with no transport terms (u and D = 0) and modify to be consistent with the definition of the open system mode in geochemical modelling. The ability of KIRMAT to treat multicomponent pure advective transport, subjected to several kinetically equilibrium-controlled dissolution and precipitation reactions, and to track their boundaries has been successfully verified with the property of interest. The required numerical validation of the reference calculations is bypassed in developing the Eulerian code from an already checked single reaction path code. A forward time-upstream weighting scheme (a mixing cell scheme) is used in this study. An appropriate choice of grid spacing allows to calculate within the grid size uncertainty the correct mineral reaction zone boundaries, despite the presence of numerical dispersion. Its correction enables us to improve the convergence and to extend the numerical test to mixed advective-dispersive mass transport. However, the skewness factor involves numerical oscillations that prevent to compute different grid spacing. The use of a different controlled time step constraint in both calculations induces some inconsistencies into the validation tests. This numerical validation method may be applied as well as to check a thermo-kinetic hydrochemical finite element based code, from a 1D heterogeneous systems, and 2D-3D systems provided that they are designed so as to be 1D equivalent. A one-step algorithm and the use of a numerical reference coming from the Eulerian code to be tested ensure the potential success (accuracy) of the numerical validation method.

For NMR and X-ray crystallography, proteins in the tens of milligrams are needed. One can control many of the variables needed to successfully overproduce heterologous proteins in Escherichia coli. These include vectors, promoters and signals for translational initiation and transcriptional termination. There are several variables intrinsic to the coding region of genes that one has less control over. These include impediments to transcription and translational elongation, mRNA stability and codon usage. Although some of these can be identified by mutational analysis, this can be a difficult, time consuming and expensive process. One strategy used to eliminate the negative effects of rare codons when overproducing a protein in E. coli is to have multiple plasmid borne copies of the tRNA genes corresponding to the problematic codons. The genome of Methanococcus jannaschii has a GC content of about 30%, hence the codon usage of genes from this organism is skewed favoring A or T at the third position and overproduction of M. jannaschii proteins in E. coli can be problematic. In particular, two codon preferences for arginine (AGG and AGA) and one for isoleucine (AUA) in M. jannaschii and P. aerophilum are very rare in E. coli. We decided to test if extra plasmid copies of the tRNA genes required for decoding AGG and AGA (arginine) and AUA (isoleucine) codons would increase the amount and quality of archaeal proteins overproduced in E. coli.

AN - 79672976; 9435255 AB - In this report we document the creation of transgenic mice in which the native ratio of A and B forms of progesterone receptor (PR) has been altered by the introduction of additional A form as transgene. We also show that in these mice there is an aberration in mammary development. In ovariectomized prepubertal PR-A transgenic mice, end buds with unusual morphology persist after ovariectomy, and in young adult nonovariectomized mice, mammary glands have extensive lateral branching. The glands of adult mice also exhibit ductal hyperplasia with a disorganized basement membrane and decreased cell-cell adhesion, features commonly associated with neoplasia. Because progesterone is a mitogenic hormone in mammary glands and PR is required for mammary development, these data provide direct evidence that in vivo a regulated expression of the two isoforms of PR is critical for appropriate cellular response to progesterone and that for mammary glands this may have major implications to carcinogenesis.

AN - 79631277; 11542785 AB - Two assay were employed to study the induction and repair of DNA double-strand breaks (dsbs) in normal human fibroblasts after exposure to particle radiation covering an LET range from 1 to 350 keV/micrometer. The hybridization assay allows measurement of absolute induction frequencies in defined regions of the genome and quantitates rejoining of correct DNA ends while the FAR assay determines all rejoining events, correct and incorrect. Assuming Poisson statistics for the number of breaks per DNA fragment investigated, and thus neglecting any clustering of breaks, we found the induction rate to decrease with increasing LET of the particles. RBE values compared to 225 kVp X-rays dropped to 0.48 for the highest LETs. Repair studies of X-ray-induced dsbs showed that almost all breaks (>95%) are rejoined after incubation times of 24 h while the frequency for correct rejoining is only 70%. Thus about 25% of the initially induced breaks are rejoined by the connection of incorrect DNA ends. Postirradiation incubation after particle irradiation showed less efficient total rejoining with increasing LET and an impaired ability for correct rejoining. The frequency for rejoining of incorrect DNA ends was found to be independent of LET. The possible biological significance of the different rejoining events is discussed.

AN - 69256096; 11541622 AB - This paper surveys some recent accelerator-based measurements of the nuclear fragmentation of high energy nuclei in shielding and tissue-equivalent materials. These data are needed to make accurate predictions of the radiation field produced at depth in spacecraft and planetary habitat shielding materials and in the human body by heavy charged particles in the galactic cosmic radiation. Projectile-target combinations include 1 GeV/nucleon 56Fe incident on aluminum and graphite and 600 MeV/nucleon 56Fe and 290 MeV/nucleon 12C on polyethylene. We present examples of the dependence of fragmentation on material type and thickness, of a comparison between data and a fragmentation model, and of multiple fragments produced along the beam axis.

Until recently, understanding of the atomic scale structure of solid solutions has been limited. We have analyzed divalent Co, Zn, Pb, and Ba XAFS spectra of synthetic and natural trace-element containing calcite samples to determine the local distortion and relaxation around these impurities substituting for Ca. The octahedral coordination found for Ba is noteworthy because of its large size (35% larger than host Ca) and the fact that it rarely exists as a major constituent with such a low coordination number. Multishell fits of XAFS spectra show a nearly complete contraction of the structure around divalent Co and Zn. The Co-O and Zn-O first-shell distances are only slightly longer than in CoCO (sub 3) and ZnCO (sub 3) , with a site compliance of 80-90%. The dilation around the large divalent Pb and Ba ions in calcite also shows a high site compliance. More distant C, O, and Ca shells for all samples show displacements relative to those in pure calcite that decrease rapidly with radial distance, revealing that the relaxation is mostly confined within roughly 6 7 Aa around the impurity, although the dilation around Ba may have a slightly greater radial extent. Comparison of these observations with XAFS studies of other solid solutions suggests that the compliance of the octahedral site in calcite is larger than for the cation site in the rocksalt structure, where significant variation of first-shell interatomic distances with composition has been found. The high compliance for the metal site in calcite may reflect the corner-sharing topology of the structure, and may also be the reason that calcite shows such a wide range of isovalent substitutions in nature. The findings provide a direct indication of the localized strain associated with a dilute substitutional solid solution of calcite and may be applicable to solutions involving other rhombohedral carbonates.

The (super 132) Xe/ (super 36) Ar ratios are as high as approximately 576 times the ratio in air and represent the largest relative Xe-enrichments ever observed in terrestrial fluids. The isotopic composition of this component is indistinguishable from air. Based upon earlier laboratory studies, we believe that the source of this Kr, Xe enriched component was air initially trapped in the petroleum source rocks which was subsequently expelled and mixed with hydrocarbons during oil formation and expulsion. The Kr and Xe enrichments are positively correlated with each other but inversely correlated with (super 36) Ar concentration. Here we propose a model in which Kr-Xe-enriched oil becomes diluted with noble gases extracted from air saturated groundwater during hydrocarbon expulsion, migration, and/or storage. The model generates an integrated production fluid water/oil ratio of approximately 6-80 gm-water/gm-carbon. We conclude from these low water/oil ratios that aqueous solution of oil and methane has had a limited role in the generation, migration, and accumulation of hydrocarbons in southern San Joaquin Basin. This is in agreement with inferences made from absolute and differential solubilities of heavy and light oils in water. It is likely that effective diffusivities of noble gases in water control the rate at which oils acquire noble gases from air saturated water. Water-oil exposure times for given geometries can be evaluated, since the volume of water in diffusive contact is constrained by the model derived water/oil ratios.

The Drift Scale heater Test (DST) centers around a 47. 5-m-long, 5-m-diameter heated drift. Heat released from emplaced nuclear waste is simulated with 9 canister and 50 wing electrical heaters. Heating was initiated on December 3, 1998 at a power of 188 kW. The planned heating period of the DST is four years, followed by a cooling period of similar duration. The DST is situated in non-lithophysal, intensely fractured partially saturated welded tuff. While water is held mainly in the very low permeability matrix, the fractures are mostly air-filled. Pre-heat characterization of the DST test block by cross-hole air permeability tests show that the fractures are well connected, forming a heterogeneous continuum with permeability values ranging from millidarcy to a few darcies. Heat generated from waste in a high-level nuclear waste repository causes water to boil, and moisture is transported in the vapor phase and condenses in cooler region. The thermal hydrological processes encountered in the DST are studied via continuous monitoring of temperature, gas pressure, and humidity in the rock mass. In addition, active testing through cross-hole ground penetrating radar surveys, cross-hole air injection tests, and gas tracer tests, are conducted periodically. Increases in liquid saturation in the fractures due to condensation is reflected by a reduction of local air permeability values. Changes in matrix liquid saturation will also be reflected in cross-hole radar tomograms. Predictions of the thermal-hydrological conditions of the DST have been carried out prior to the start of the DST. Both the passive monitoring and active testing data for the first six months of heating have been compared to simulated results. The agreement between prediction and measurements is good, providing much valuable insight into coupled processes.

Modeling results indicate that the wetting front generally propagates fast along fractures with relatively weak matrix imbibition. Influx into drift will not be observed until local accumulation of water above the drift ceiling overcomes the capillary barrier effect of the drift. A sensitivity study with a simple cylindrical model was used to explain the field detection of large influx at an underground alcove (Alcove 1) observed nearly 2 months after the onset of infiltration. Probes were installed in boreholes in the alcove to monitor the moisture changes of fracture network system within an infiltration test zone. Similar probes were installed at the starting point of a new drift (the Cross Drift) and at the cross-over point in an existing drift (the ESF Main Drift) below the new drift to detect the construction water from the Tunnel Boring Machine. Preliminary analyses indicated that flow paths through fractured tuff could be localized and the construction water migration could be detected approximately 10 m below the drift. From the construction water migration predictions, the drift influx was shown to be sensitive to the construction water release rate of the TBM. If construction water loss is less than 100 liters per meter of excavation, little or no influx is expected using a set of parameters for a highly connected, homogeneous fracture network. The model results were compared with observations made at the cross-over point below as the TBM passed over. Similar models with local heterogeneities in the fracture network could explain the observed tracer signatures found in cores of boreholes drilled below the ESF. The comparisons between modeling and field monitoring results in these underground alcove and borehole studies lead to better understanding of large-scale processes of liquid flow and transport in unsaturated, fractured porous media.

To properly map out the spatial heterogeneity, the packed borehole intervals were chosen to be nominally 0.3 m long. For the seven-borehole cluster at Niche 3650, approximately 50,000 curves of pressure response were generated in the cross-hole tests. Overall permeability of the known fast-path niche (Niche 3566) is higher than that of the bomb-pulse-fast-path-free niche (Niche 3650). The tests were conducted in the borehole clusters before and after niche excavation. At Niche 3650, the permeability values measured after niche excavation were about two orders of magnitude larger than those measured before niche excavation. At Niche 3566, the radial boreholes through brecciated zones tested inside the niche had significantly higher permeability values than the axial boreholes parallel to the niche axis drilled through relatively competent rock mass. Similar numbers of tests were also conducted at Niche 3107 below a lithophysal-non-lithophysal contact, at Niche 4788 in an extensively fractured zone, at the fracture-matrix interaction test bed in Alcove 6, and at the Paintbrush non-welded flow test bed in Alcove 4. An automated data collection system was developed to systematically select the test interval and collect the cross-hole data. The air permeability test results were used to characterize the test sites, select borehole intervals for liquid releases, and quantify the spatial variability which could have significant effects on the predictions of the unsaturated zone drift scale model for the Yucca Mountain site.

Volumes of liquid were released in boreholes above the niches to represent the arrival of episodic fast flow events at the repository horizon. Of the 16 zones tested, water seeped into the niche from 10 intervals, water appeared at the niche ceiling but did not drip in 3 cases, and water did not appear at all when introduced into the 3 remaining zones. The seepage percentage, defined as the amount of water seeped into the niche divided by the amount released into the rock, ranged from 0% to 56%, with the anomalous high value corresponding to a test that started within 2 hours of a preceding test conducted on the same interval. Based on repeat experiments with different time periods between tests, redistribution of injected water in the fracture system appears to occur within one day to two weeks. As the liquid release rate decreased, seepage percentage decreased until reaching a seepage threshold, below which no seepage occurs. The relationships between seepage threshold data and saturated hydraulic conductivity values were used to derive two capillarity or sorptivity related parameters, representing two types of in situ fractures: nearly vertical individual fractures and a network of interconnected fractures. Steady downward flow through homogeneous porous medium and other simple assumptions were used to interpret the fitting parameters. The field test results also substantiated model interpretations using simple two- and three-dimensional models for transient niche seepage processes. The seepage test results from this and other five niches are used to calibrate the unsaturated zone drift scale model for input to the total system performance assessment of the Yucca Mountain site.

Conventional sampling or borehole techniques used for characterization are costly and invasive, and limit collection of measurements at a density needed for detailed site investigation. The purpose of this paper is to explore the use geophysical data for estimation of hydrogeological parameters and their spatial correlation structure. The first two methodologies presented focus on producing high resolution estimates of hydrological properties using densely sampled geophysical data and limited borehole data. Although we find that high resolution geophysical data are useful for obtaining these estimates, in practice they often sample only a portion of the aquifer under investigation. Stochastic simulation techniques are commonly used to generate hydrogeological values for the rest of the study volume; these techniques require as input information about the parameter's spatial covariance structure. The third and last section focuses on using high resolution tomographic data together with limited borehole data to infer the log-permeability spatial correlation structure.

The highest reservoir Cl concentrations are found on the West Bank, but stand in apparent conflict with maximum reservoir pressure values found in the east. B/Cl, N (sub 2) /Ar and CO (sub 2) /He maxima all occur on the East Bank. The current model holds that there are two heat sources in the present-day system, with that on the East Bank comprised of an actively degassing and relatively shallow-seated magmatic intrusion.

This paper reviews the general guidelines for drinking water quality and the scale of the global problem. It reviews the various water disinfection technologies that may be applicable to achieve the desired quality of drinking water in developing countries. It then summarizes financing problems that deter extending access to safe drinking water to the unserved population and identifies feasible policy positions for enhancing availability of drinking water in these countries.

The transient diffusion equation proposed by Fourier early in the 19th century for heat conduction in solids constitutes the basis for inverting hydraulic test data collected in the field to estimate the two basic parameters of interest, namely, hydraulic conductivity and hydraulic capacitance. Combining developments in fluid mechanics, heat conduction, and potential theory, the civil engineers of the 19th century, such as Darcy, Dupuit, and Forchheimer, solved many useful problems of steady state seepage of water. Interest soon shifted towards the understanding of the transient flow process. The turn of the century saw Buckingham establish the role of capillary potential in governing moisture movement in partially water-saturated soils. The 1920s saw remarkable developments in several branches of the Earth sciences; Terzaghi's analysis of deformation of watersaturated earth materials, the invention of the tensiometer by Willard Gardner, Meinzer's work on the compressibility of elastic aquifers, and the study of the mechanics of oil and gas reservoirs by Muskat and others. In the 1930s these led to a systematic analysis of pressure transients from aquifers and petroleum reservoirs through the work of Theis and Hurst. The response of a subsurface flow system to a hydraulic perturbation is governed by its geometric attributes as well as its material properties. In inverting field data to estimate hydraulic parameters, one makes the fundamental assumption that the flow geometry is known a priori. This approach has generally served us well in matters relating to resource development primarily concerned with forecasting fluid pressure declines. Over the past two decades, Earth scientists have become increasingly concerned with environmental contamination problems. The resolution of these problems requires that hydraulic characterization be carried out at a much finer spatial scale, for which adequate information on geometric detail is not forthcoming. Traditional methods of interpretation of field data have relied heavily on analytic solutions to specific, highly idealized initial-value problems. The availability of efficient numerical models and versatile spreadsheets of personal computers offer promising opportunities to relax many unavoidable assumptions of analytical solutions and interpret field data much more generally and with fewer assumptions. Currently, a lot of interest is being devoted to the characterization of permeability. However, all groundwater systems are transient on appropriate timescales. The dynamics of groundwater systems cannot be understood without paying attention to capacitance. Much valuable insights about the dynamic attributes of groundwater systems could be gained by long-term passive monitoring of responses of groundwater systems to barometric changes, Earth tides, and ocean tides.

This paper reviews the general guidelines for drinking water quality and the scale of the global problem. It reviews the various water disinfection technologies that may be applicable to achieve the desired quality of drinking water in developing countries. It then summarizes financing problems that deter extending access to safe drinking water to the unserved population and identifies feasible policy positions for enhancing availability of drinking water in these countries.

Greenhouse gas emissions from the developing world are rising faster than those from other countries, and many studies have noted that it would not be possible to stabilize climate change without reducing the growth of these emissions. Can this be achieved without affecting economic growth and social fabric in these countries? Mitigation studies indicate that if energy efficiency and forestry options are implemented judiciously, emissions can be reduced at a negative cost without affecting economic growth. The studies also suggest that this would increase significantly the worldwide demand for natural gas and renewable technologies. Country studies show that the aggregate mitigation potential in the forestry sector is higher, and the costs per tonne of carbon are lower, than reported earlier by global studies. Barriers to the implementation of energy and forestry options need to be explicitly taken into consideration because these may change the priority of options and the choice of policy measures.

Information about the three-dimensional folds of these proteins may provide insight into their possible functions. To predict the folds for protein sequences with little or no homology to proteins of known function, we used computational neural networks trained on the database of proteins with known three-dimensional structures. Global descriptions of protein sequences based on physical and structural properties of the constituent amino acids were used as inputs for neural networks. Of the 131, 498, and 868 protein sequences of unknown function from Mycoplasma genitalium, Haemophilus influenzae, and Methanococcus jannaschii (Fleischmann et al. 1995), we have made high-confidence fold assignments for 4, 10, and 19 sequences, respectively.

Office worker response to the system and occupant-based modifications to the control system are investigated to determine if the design and operation of the prototype system can be improved. Key findings from the study are: (1) the prototype integrated envelope and lighting system is ready for field testing, (2) most office workers (N = 14) were satisfied with the system, and (3) there were few complaints. Additional studies are needed to explain how illuminance distribution, lighting quality, and room design can affect workplace illuminance preferences.

Lipoprotein(a) assembly with human and rabbit apolipoprotein B AN - 16274729; 4284349 AB - The in vivo analysis of lipoprotein(a) (Lp(a)), an independent atherosclerosis risk factor in humans, has been limited in part by its restricted distribution among mammals. Although transgenic mice have been created containing Lp(a), the relatively small size of the mouse has precluded some studies. To examine the properties of this molecule in a significantly larger mammal, we have used a 270-kilobase yeast artificial chromosome clone containing the human apolipoprotein(a) (apo(a)) gene and a 90-kilobase P1 phagemid clone containing the human apolipoprotein B (apoB) gene to create transgenic rabbits that express either or both transgenes. Expression of both transgenes was tissue specific and localized predominantly to the liver. Average apolipoprotein plasma levels in the rabbits were 2.5 mg/dl for apo(a) and 17.6 mg/dl for human apoB. In contrast to observations in apo(a) transgenic mice, we found that apo(a) plasma levels in the rabbits were stable throughout sexual maturity. Also, apo(a) formed a covalent association with the endogenous rabbit apoB albeit with a lower efficiency than its association with human apoB. The analysis of Lp(a) transgenic rabbits has provided new insights into apo(a) expression and Lp(a) assembly. In addition, these transgenic rabbits potentially will provide an improved experimental model for the in vivo analysis of Lp(a) and its role in promoting atherosclerosis and restenosis.

Realization of clinical and medical science applications beyond lung airspace imaging requires methods of efficient delivery of laser-polarized xenon to tissues. because of the short spin-lattice relaxation times and relatively low concentrations of xenon attainable in the body. Preliminary results from the application of a polarized xenon injection technique for in vivo super(129)Xe NMR/MR1 are extrapolated along with a simple model of xenon transit to show that the peak local concentration of polarized xenon delivered to tissues by injection may exceed that delivered by respiration by severalfold.

AN - 79463792; 9398663 AB - Examination of the process of immortal transformation in early passages of two human mammary epithelial cell (HMEC) lines suggests the involvement of an epigenetic step. These lines, 184A1 and 184B5, arose after in vitro exposure of finite lifespan 184 HMEC to a chemical carcinogen, and both are clonally derived. Although early-passage mass cultures of 184A1 and 184B5 maintained continuous slow growth, most individual cells lost proliferative ability. Uniform good growth did not occur until 20-30 passages after the lines first appeared. Early-passage cultures expressed little or no telomerase activity and telomeres continued to shorten with increasing passage. Telomerase activity was first detected when the telomeres became critically short, and activity levels gradually increased thereafter. Early-passage cultures had little or no ability to maintain growth in transforming growth factor-beta (TGFbeta); however, both mass cultures and clonal isolates showed a very gradual increase in the number of cells displaying progressively increased ability to maintain growth in TGFbeta. A strong correlation between capacity to maintain growth in the presence of TGFbeta and expression of telomerase activity was observed. We have used the term "conversion" to describe this process of gradual acquisition of increased growth capacity in the absence or presence of TGFbeta and reactivation of telomerase. We speculate that the development of extremely short telomeres may result in gradual, epigenetic-based changes in gene expression. Understanding the underlying mechanisms of HMEC conversion in vitro may provide new insight into the process of carcinogenic progression in vivo and offer novel modes for therapeutic intervention.

These relationships for the pores of four sandstones were found to lie between 1.43 and 1.49, while that of an Indiana limestone was found to be 1.67. We show how the perimeter-area power-law relationship of pores, along with a pore-size distribution, can be used to estimate the hydraulic permeability. A discussion is given of how the fractal dimension of the pore perimeter derived by Mandelbrot for islands whose boundaries are fractal: P = l (super D) A (super D/2) , where l is some constant that depends on the length of the measuring grid size and D is the fractal dimension of the pore perimeter and influences permeability.

More than half of the 4000+ events in our 1987 to 1996 catalog exhibit this trait. In general, recurrence intervals (0.5 to 2 yr) scale with the magnitude of the repeating events for the on-scale range (Mw 0.2 to 1.3) in this study. The similar waveforms, superimposed locations, quasi-periodic recurrence, and uniform size of these characteristic events permit relative hypocenter location accuracy of meters and predictable occurrence times within windows of a few months. Clustered characteristic events occur at depths as shallow as about 3 km, and these are feasible targets for deep scientific drilling and observation at the focus of a subsequent small earthquake within an active plate-boundary fault zone. At Parkfield, the achievable location accuracy to which a hypocenter can be specified as well as the predictability of its occurrence time appear to be uniquely favorable for in situ fault-zone measurements.

These new technologies will soon enable rapid screening of populations at risk, as well as the broader public, for a variety of genes known to be associated with increased risk. These include specific oncogenes, tumor suppressor genes and DNA repair enzymes. Use of these technologies also presents a number of ethical issues, both in screening and in use of the information about individuals. Overall, the use of rapid genotyping technologies will introduce a specificity and possible group identifiers that will present new challenges to the determination of risk within the EPA mandate.

Yet, the variability and complexity of biological systems pose unique challenges in model building and adjustment. Recent tools from Bayesian statistical inference can be brought together to solve these problems. As an example, the authors modeled the development of biofilm in an industrial pilot drinking-water network. The relationship between chlorine disinfectant, organic carbon, and bacteria concentrations was described by differential equations. Using a Bayesian approach, they derived statistical distributions for the model parameters, on the basis of experimental data. The model was found to adequately fit both prior biological information and the data, particularly at chlorine concentrations between 0.1 and 2 mg/liter. Bacteria were found to have different characteristics in the different parts of the network. The model was used to analyze the effects of various scenarios of water quality at the inlet of the network. The biofilm appears to be very resistant to chlorine and confers a large inertia to the system. Free bacteria are efficiently inactivated by chlorine, particularly at low concentrations of dissolved organic carbon.

AN - 79460749; 9371767 AB - It has previously been reported that 1,N6-ethenoadenine (epsilonA), deaminated adenine (hypoxanthine, Hx), and 7,8-dihydro-8-oxoguanine (8-oxoG), but not 3,N4-ethenocytosine (epsilonC), are released from DNA in vitro by the DNA repair enzyme alkylpurine-DNA-N-glycosylase (APNG). To assess the potential contribution of APNG to the repair of each of these mutagenic lesions in vivo, we have used cell-free extracts of tissues from APNG-null mutant mice and wild-type controls. The ability of these extracts to cleave defined oligomers containing a single modified base was determined. The results showed that both testes and liver cells of these knockout mice completely lacked activity toward oligonucleotides containing epsilonA and Hx, but retained wild-type levels of activity for epsilonC and 8-oxoG. These findings indicate that (i) the previously identified epsilonA-DNA glycosylase and Hx-DNA glycosylase activities are functions of APNG; (ii) the two structurally closely related mutagenic adducts epsilonA and epsilonC are repaired by separate gene products; and (iii) APNG does not contribute detectably to the repair of 8-oxoG.

AN - 79574490; 9520127 AB - Despite the importance of lipoprotein(a) [Lp(a)] as an atherogenic risk factor, very little information, especially from in vivo studies, is available concerning which structural features of apo(a) contribute to the interactions of Lp(a) with the vessel wall and its proatherogenic properties. Nearly all the proposed and proven activities of apolipoprotein(a) [apo(a)] focus on its high degree of sequence homology with plasminogen and the possibility that structural features shared by these two molecules contribute to the atherogenesis associated with high Lp(a) plasma levels in humans. In these studies, we examined the properties of three forms of Lp(a) differing at postulated lysine-binding domains contained in the constituent apo(a). We used the recombinant adenoviral gene delivery system to produce apo(a) in the plasma of human apoB transgenic mice, resulting in high levels of Lp(a) similar to those found in the plasma of humans. By comparison of in vitro lysine-binding properties of these forms of Lp(a) with measurements of Lp(a) vascular accumulation in the mice, we have demonstrated that lysine-binding defective forms of Lp(a) have a diminished capacity for vascular accumulation in vivo.

AN - 79448357; 9392429 AB - Human carriers of apolipoprotein A-I(Milano) (Arg173 --> Cys substitution in apolipoprotein A-I) are characterized by an HDL deficiency in which small, dense HDL accumulate in plasma. Because affected individuals are heterozygous for this mutation, the full impact of apolipoprotein A-I(Milano) (apoA-I(Milano)) on HDL-cholesterol metabolism is unknown. In this study, apoA-I(Milano) transgenic mice were used to evaluate the extent of apoA-I(Milano) dimerization and HDL particle size restriction in the absence of wild-type apoA-I. Murine apoA-I knockout mice were utilized to express apoA-I(Milano) and human apoA-II in the presence of wild-type, human apoA-I (apoA-IMilano/A-Iwt/A-II) and in its absence (apoA-IMilano/A-II). Plasma HDL-cholesterol concentrations were similar (30 mg/dl) in both lines of apoA-I(Milano) transgenic mice. In the apoA-IMilano/A-Iwt/A-II phenotype, 14% of the apoA-I(Milano) formed homodimers and 33% formed heterodimers with apoA-II. ApoA-I(Milano) homodimers increased by 71% in the apoA-IMilano/A-II transgenics and was associated with an abundance of small, 7.6-nm HDL3-sized particles compared to the 9.5, 8.3, and 7.6-nm-sized particles in apoA-IMilano/A-Iwt/A-II mice. The unesterified cholesterol/cholesteryl ester mole ratio of HDL was elevated by 45% in apoA-IMilano/A-Iwt/A-II mice and by 90% in apoA-IMilano/A-II transgenics compared to wild-type (human apoA-I/A-II). Both apoA-I(Milano) transgenics possessed normal levels of plasma LCAT activity, but endogenous cholesterol esterification rates were reduced by 50% compared to controls. Thus, HDL particle size restriction was not the result of impaired LCAT activation; rather, dimerization of apoA-I(Milano) limited the esterification of cholesterol on endogenous HDL. In the absence of wild-type apoA-I, the more extensive dimerization of apoA-I(Milano) severely limited cholesteryl ester accumulation on plasma HDL accounting for the abundance of small, 7.6-nm HDL3 particles in apoA-IMilano/A-II mice.

AN - 79385315; 9356539 AB - In a national survey, 199 male and 152 female vegetarian runners and 7054 male and 1837 female omnivorous runners provided data on weekly intakes of alcohol, red meat, fish, and fruit, and weekly distance run. This information was compared with physician-supplied medical data to test whether 1) running benefits vegetarians, 2) alcohol and running distance contribute independently to concentrations of high-density-lipoprotein (HDL) cholesterol, and 3) running mitigates the hypertensive effects of alcohol. Greater reported weekly distance run by vegetarians was associated with greater HDL-cholesterol concentrations [slopes +/- SEs for men and women, respectively: 0.003 +/- 0.001 and 0.005 +/- 0.002 (mmol/L)/km] and lower waist (-0.06 +/- 0.02 and-0.08 +/- 0.02 cm/km), hip (-0.05 +/- 0.03 and -0.07 +/- 0.02 cm/km), and chest (-0.05 +/- 0.02 cm/km for both) circumferences. In men and women, alcohol and running distance contributed independently to higher HDL-cholesterol concentrations. Men who ran > 72 km and drank > 177 mL (6 oz) alcohol/wk were five times more likely to have clinically defined high HDL cholesterol (> or = 1.55 mmol/L, or > or = 60 mg/dL) than were nondrinkers running < 24 km/wk. Regardless of running level, men's blood pressure increased in association with alcohol intake. These data suggest that 1) running distance in vegetarians and vegans has the same relation to HDL cholesterol (increasing) and adiposity (decreasing) as reported previously for omnivores, 2) alcohol and running distance contribute independently to higher HDL cholesterol, and 3) running does not abate the hypertensive effects of alcohol in men. Also, vigorous exercise provides important health benefits beyond those obtained by diet.

Water content estimates are needed, for example, to model and predict pollutant transport through the vadose zone and to subsequently design an efficient and reliable remediation plan. The characteristics of preferential flow paths, as well as the location and geometry of these features, are necessary to model and predict flow and transport in complex geological media such as fractured or strongly heterogeneous porous systems.

Scanning Electron Microscopy (SEM) is used to inspect the fracture surfaces and it is found that fracture propagation occurs through a process of grain debonding and ejection from the sample. A two-dimensional boundary integral simulation models the effect of grain removal on subsequent fracturing by reducing the Young's modulus of failed grains, thereby allowing the compressive loading stress to be transferred to adjoining grains and grain contacts. It is found that this stress concentration is sufficient to induce additional grain failure and macroscopic fracture growth perpendicular to the applied load.

Because of the uncertainty inherent in subsurface transport prediction, an integral part of predictive modeling is uncertainty analysis. We have investigated the uncertainty of simulated trichloroethylene (TCE) concentrations due to parameter uncertainty and variation in conceptual model. The transport simulation is performed with T2VOC, a three-dimensional integral finite difference code for three-phase (gas, aqueous, non-aqueous phase liquid), three-component (air, water, volatile organic compound), nonisothermal subsurface flow. Our modeling is based on an actual site and considers a three-dimensional system with a thick vadose zone (25 m) into which 35,000 kg of TCE was disposed of in surface trenches over 10 years. Subsurface transport involves TCE moving in the vadose and saturated zones from the source trench toward a nearby residence and includes the processes of advection, diffusion, and adsorption over extended distances and timescales. Uncertainties in the calculated concentrations due to variance in the major transport parameters are quantified using the inverse modeling code ITOUGH2. ITOUGH2 calculates uncertainty in the T2VOC simulation by both first-order, second-moment (FOSM) and Monte Carlo analyses. Significant uncertainty in simulated TCE concentrations at a site of potential human exposure is observed owing to uncertainty in permeability, porosity, diffusivity, chemical solubility, and adsorption within a single conceptual model. For the case study considered the linear FOSM analysis generally captures the uncertainty range calculated by the more accurate Monte Carlo method. Calculations also show that significant output uncertainty is introduced by conceptual model variation. Because human exposure and health risk depend strongly on contaminant concentrations, risk assessment and remediation selection based on transport simulation is meaningful only if the analysis includes quantitative estimates of transport simulation uncertainty.

It has often been noted that mutation is favored in certain sequence contexts, sometimes termed 'hot spots'. This approach to the contribution of neighboring sequences does not permit a systematic study of both the qualitative and quantitative mutational frequencies. In the present experiments we have chosen to use the exocyclic adduct, 1,N super(6)-etheno A ( epsilon A), site-specifically placed in a defined 25-mer oligonucleotides in which epsilon A is flanked by differing 5' and 3' tandem bases. Mutation was assessed using an in vitro replication assay and five polymerases of varying fidelity. The relevant central sequences were 3' arrow right 5' -CC- epsilon A-CC-, -GG- epsilon A-GG-, -TT- epsilon A-TT-, -AA- epsilon A-AA-, -GG- epsilon A-TT-, -TT- epsilon A-AA-, -AT- epsilon A-TT- and -TA- epsilon A-TA-. Using the Klenow fragment (Kf) (exo super(+) or exo super(-)) of E.coli Pol I, it was found the epsilon A is an ambiguous base and, with varying efficiencies, all four dNTPs could be inserted opposite epsilon A in all sequences. However, only 3' arrow right 5' -TT- epsilon A-TT-, -GG- epsilon A-TT- and -AT- epsilon A-TT- were fully extended to a significant extent. The only sequences essentially blocked at the position of epsilon A were -AA- epsilon A-AA- and -TT- epsilon A-AA-. The others were intermediate. When replication was performed with Sequenase, MMLV RT or HIV RT, different patterns were observed, in which replication terminated one base prior to epsilon A, at epsilon A, or one base after epsilon A without further extension. In favored sequences, using the Klenow fragment, an epsilon A times N pair could be extended to form normal basepairs. No extension could be demonstrated in sequences in which tandem adenines were 5' to epsilon A. Kinetic data showed that two of the epsilon A times N pairs, epsilon A times A and epsilon A times C, could form at 10 mu M or less dNTP. Which bases were preferentially inserted opposite epsilon A was a function of the flanking bases. Under the kinetic conditions used, epsilon A times T did not form even at 1 mM dTTP. These results indicate that the chemical structure of an adduct is not the only determinant of mutagenic efficiency. It is likely that the effect of the adduct on replication is due to the changes in the structural environment conferred by the flanking bases.

Recently, highly differentiated cultured lung epithelial cell lines grown with basolateral side feeding technique have become available that can mimic airspace, epithelium, and interstitium of lung parenchyma. Cultured lung epithelium coupled with Ussing's short-circuit current technique was used as a cellular model system for lung preservation. A parametric study was conducted to correlate the effects of luminal fluid composition (University of Wisconsin (UW) solution and phosphate-buffered saline) and storage gas (air vs nitrogen) at 4 degree C for 24 h on postischemic electrogenic properties (transepithelial ion transport and resistance). The results showed that cells were better preserved with the UW solution on both sides as measured by their transepithelial resistance, an indicator of tight junction integrity (R sub(te) similar to 65% of control values similar to 135 Omega cm super(2)). In addition, they responded better to mediators that stimulate chloride secretion than cells preserved with other conditions. Cells preserved with no additional fluid on the apical side had substantially lowered R sub(te) (<20%) than those preserved with an additional thin layer of fluid ( similar to 35-65%). This cellular model system is a realistic representation of lung epithelium and can provide an accurate assessment of preservation quality through the measurements of tight junction integrity and active ion transport.

AN - 79335455; 9334193 AB - Monochloramine derivatives are long lived physiological oxidants produced by neutrophils during the respiratory burst. The effects of chemically prepared monochloramine (NH2Cl) on protein kinase C (PKC) and PKC-mediated cellular responses were studied in elicited rat peritoneal neutrophils and human Jurkat T cells. Neutrophils pretreated with NH2Cl (30-50 microM) showed a marked decrease in the respiratory burst activity induced by phorbol 12-myristate 13-acetate (PMA), which is a potent PKC activator. These cells, however, were viable and showed a complete respiratory burst upon arachidonic acid stimulation, which induces the respiratory burst by a PKC-independent mechanism. The NH2Cl-treated neutrophils showed a decrease in both PKC activity and PMA-induced phosphorylation of a 47-kDa protein, which corresponds to the cytosolic factor of NADPH oxidase, p47(phox). Jurkat T cells pretreated with NH2Cl (20-70 microM) showed a decrease in the expression of the interleukin-2 receptor alpha chain following PMA stimulation. This was also accompanied by a decrease in both PKC activity and nuclear transcription factor-kappaB activation, also without loss of cell viability. These results show that NH2Cl inhibits PKC-mediated cellular responses through inhibition of the inducible PKC activity.

AN - 79401714; 9356295 AB - The 900-kDa botulinum neurotoxin complex serotype A has been crystallized by the lipid-layer two-dimensional crystallization technique. Based on the binding characteristics of the hemagglutinating portion of the complex, a number of ganglioside/ lipid mixtures were tested but only lactosyl ceramide/1-palmityl-2-oleoyl-sn-glycero-3-phosphocholine was found to crystallize the complex. The optimum lipid mixture contained 75 mass % lactosyl ceramide and 25 mass % 1-palmityl-2-oleoyl-sn-glycero-3-phosphocholine. Using protein concentrations from 5 to 500 micrograms/ml and pH and 5 acetate buffer, we have obtained crystals that diffract to better than 15 A when prepared in negative stain. A projection map with a resolution of 30 A was calculated with unit cell dimensions of a = b = 157 A and P3 symmetry. The complex is triangular in shape with six distinct lobes observed. Additionally, six smaller structures protrude from the triangular core.

Different saturation scenarios were applied varying from fully saturated to highly unsaturated conditions, corresponding to different infiltration rates into the soil. It was found that the solute travels along preferred flow paths, which may be called channels. The degree of channeling, the location of channels, and the hydraulic properties along channels are a function of the mean saturation in the flow domain. Strong channeling effects were obtained in both fully saturated and in low-saturation cases. At intermediate saturation values, channeling effects are less significant, and the system exhibits a more homogeneous flow pattern. The dispersion of solutes as shown in the calculated tracer breakthrough curves essentially reflects the degree of channeling and thus is saturation dependent; in cases when flow channeling is less evident we observe much smaller dispersion than in cases with strong channeling. The hydraulic properties of the channels appeared to be an invariant of the actual location and geometry, indicating that they may be an intrinsic characteristic of the soil heterogeneity and the water saturation.

In vivo analysis of the role of lysine binding sites using recombinant adenovirus. AN - 79277667; 9294116 AB - Although the mechanism by which lipoprotein(a) [Lp(a)] contributes to vascular disease remains unclear, consequences of its binding to the vessel surface are commonly cited in postulated atherogenic pathways. Because of the presence of plasminogen-like lysine binding sites (LBS) in apo(a), fibrin binding has been proposed to play an important role in Lp(a)'s vascular accumulation. Indeed, LBS are known to facilitate Lp(a) fibrin binding in vitro. To examine the importance of apo(a) LBS in Lp(a) vascular accumulation in vivo, we generated three different apo(a) cDNAs: (a) mini apo(a), based on wild-type human apo(a); (b) mini apo(a) containing a naturally occurring LBS defect associated with a point mutation in kringle 4-10; and (c) human- rhesus monkey chimeric mini apo(a), which contains the same LBS defect in the context of several additional changes. Recombinant adenovirus vectors were constructed with the various apo(a) cDNAs and injected into human apoB transgenic mice. At the viral dosage used in these experiments, all three forms of apo(a) were found exclusively within the lipoprotein fractions, and peak Lp(a) plasma levels were nearly identical (approximately 45 mg/dl). In vitro analysis of Lp(a) isolated from the various groups of mice confirmed that putative LBS defective apo(a) yielded Lp(a) unable to bind lysine-Sepharose. Quantitation of in vivo Lp(a) vascular accumulation in mice treated with the various adenovirus vectors revealed significantly less accumulation of both types of LBS defective Lp(a), relative to wild-type Lp(a). These results indicate a correlation between lysine binding properties of Lp(a) and vascular accumulation, supporting the postulated role of apo(a) LBS in this potentially atherogenic characteristic of Lp(a).

However, there is an unresolved issue for the structural event which initiates the transmembrane signal upon binding to the ligand. Biochemical and genetic evidence implies an intrasubunit mechanism (monomeric model) whereas crystallographic evidence implies an intersubunit mechanism (dimeric model). Crystallographic evidence has been ambiguous because all the apo protein structures contained a pseudoligand sulfate, and a completely ligand-free structure has not been available thus far. Here we present the crystal structure of the ligand binding domain of the aspartate receptor free of the ligand aspartate or pseudoligand sulfate. The structural comparison of this structure with those of ligand-bound and pseudoligand-bound forms revealed that, on ligand or pseudoligand binding, the conformational change in the ligand-binding domain is relatively small, but there is a considerable rotation between two subunits, supporting the dimeric model.

AN - 79281673; 9295108 AB - MPTP 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is a neurotoxin that produces degeneration of nigrostriatal dopaminergic neurons and a chronic parkinsonian condition in primates. Positron emission tomography (PET) studies of rhesus macaques at various time points following unilateral MPTP administration demonstrated a different time course of degeneration in the dopaminergic terminals in the putamen and in the cell bodies in the substantia nigra, consistent with other evidence of retrograde degeneration. In addition, the substantia nigra showed a transient upregulation in dopaminergic function in the lesioned hemisphere indicating functional compensation. This plasticity has important implications for the therapeutic effects of growth factors and other potential treatments for neurodegenerative diseases.

The energy region covered by this experiment is critical for an understanding of galactic cosmic ray propagation and space radiation biophysics. Surviving primary beam particles and fragments with charges from 12 to 25 produced within a forward cone of half-angle 61 mrad were detected using a silicon detector telescope to identify their charge and the cross sections were calculated after correction of the measured yields for finite target thickness effects. The cross sections are compared to model calculations and to previous measurements. Cross sections for the production of fragments with even-numbered nuclear charges are seen to be enhanced in almost all cases. JF - Physical review.

AN - 79178973; 9250405 AB - A crucial question in repair is how do enzymes recognize substrates. In surveying the relevant literature, it becomes evident that there are no rules which can be clearly applied. At this time it appears that uracil glycosylase is the only repair enzyme for which all the known substrates can be rationalized on the basis of chemical structure. When surveying the multiplicity of substrates for m3A-DNA glycosylase, it is difficult, on the basis of present knowledge, to explain why 1,N6-etheno-A (epsilon A) is as good a substrate, if not better, than m3A for which the enzyme is named. There is no apparent unifying chemical structure which is required for recognition. It should also be noted that many studies of the mechanism of m3A-DNA glycosylase only utilized-N-3- and N-7-alkylpurines. On this basis, an electron-deficient purine, and later pyrimidine, was considered to be the recognition signal. Since epsilon A and Hx do not fall in this class, this is one illustration of why exploring new substrates becomes important in elucidating enzyme mechanisms. Ubiquitous enzymes, such as 5'-AP endonucleases, are present in both prokaryotes and eukaryotes. The primary function is the same, i.e., repair of an AP site which occurs through natural processes or from the action of DNA glycosylases. There are, however, completely unrelated substrates such as the exocyclic adducts pBQ-dC and pBQ-dG. pBQ-dC is repaired by both the human HAP1 and E. coli Exo III and Endo IV, while pBQ-dG is only repaired by the E. coli enzymes. Yet, when repair of these adducts occurs, it is by the same unusual pathway which differs from the usual base excision repair mechanism. This finding may ultimately not be as unusual as it now seems. The understanding of substrate recognition by repair enzymes, which can have different repair pathways, is complex. For example, three exocyclic derivatives which each have either the same modification (1,N4-epsilon dA and 3,N4-epsilon dC) or the same base with different modifying groups (3,N4-epsilon dC and 3,N4-pBQ-dC) are repaired by three separate enzymes and two mechanism (Figure 9). Investigators have also reported that two separate enzymes and pathways can be found for simple adducts such as m6G and O4T. It is not clear why, for these adducts, both MGMT and excision repair can be utilized. This could be visualized as a "backup" system and may be more common than now known. We cannot think like an enzyme or vice versa. In the absence of enough necessary information, we can only be descriptive. What information is necessary for further understanding? (1) More detailed structural studies of adducts in defined oligonucleotides would be useful. (2) New substrates should be explored. For example, is the mechanism for PBQ-dC (and pBQ-dG) repair unique? This involves guesswork and intuition. (3) For the adducts mentioned in this Perspective and others, understanding enzyme/substrate recognition will be facilitated by cocrystallography and site-directed mutagenesis. (4) Genetic approaches, such as knockouts or targeted mutations in repair genes, should be expanded in order to focus on the physiological role of a specific enzyme. Above all: structure, structure, structure! Enzymologists, organic chemists, physical chemiste, X-ray crystallographers, and others must combine forces if the fundamental problems addressed here are to be understood.

The source is assumed to be located at the top (or the bottom) of the aquifer, and the initial concentration is assumed to be zero everywhere in the aquifer. Both constant-flux and constant-concentration sources are treated. For cases of a constant-flux source, we present exact analytical solutions considering the following transport mechanisms: advection in the horizontal direction, dispersions in both horizontal and vertical directions, adsorption, and biodegradation. For cases of a constant-concentration source, we present simplified analytical solutions by neglecting dispersion in the horizontal direction. For both kinds of sources, the solutions for aquifers with a relatively large or small thickness are presented and compared. The solutions for the two different source conditions are also compared for similar cases. The comparisons indicate that simpler solutions, used in appropriate cases, can give the same results as those given by more complex solutions. Example calculations are given to show the movement of the contamination front, the steady-state concentration profiles, and the applications to determine dispersivities. The analytical solutions developed in this study can be useful in site characterization, groundwater monitoring, and remediation.

Fluid inclusion and stable isotope analyses of secondary hydrothermal minerals in core samples from three scientific observation holes (SOH) drilled into the rift zone indicate that the geothermal system is dominated by meteoric waters to depths of as much as 1500 m below sea level. Calculated delta (super 18) O and delta D values for fluids on the north side of the rift zone indicate that the deep meteoric fluids may be derived from precipitation on the upper slopes of Mauna Loa Volcano. In the interior of the rift zone, recharge is dominated by seawater mixed with local meteoric water. Water/rock ratios in the rift area are approximately 2, but strongly (super 18) O-enriched fluids in the deeper parts of the SOH-2 and SOH-4 drill holes (on the north side of the rift) indicate that the fluids underwent extensive interaction with rocks prior to reaching this part of the rift zone. Marine carbonates at the subaerial to submarine transition (between 1700 and 1780 m depth) in SOH-4 have not fully equilibrated with the fluids, suggesting that the onset of hydrothermal activity in this area was relatively recent (<2000 years). This may represent increased volcanic activity along the rift after the end of the Ai La'au phase of eruptive activity at the Kilauea summit approximately 1000 years ago, or it may reflect progressive evolution of the hydrothermal system in response to southward migration of intrusive activity within the rift.

With sensor-based demand-controlled ventilation (SBDCV), the rate of ventilation (i.e., rate of outside air supply) also varies with time to compensate for the changes in pollutant generation. Compared to ventilation without feedback, SBDCV offers two potential advantages: (1) better control of indoor pollutant concentrations; and (2) lower energy use and peak energy demand. SBDCV has the potential to improve indoor air quality by increasing the rate of ventilation when indoor pollutant generation rates are high and occupants are present. SBDCV can also save energy by decreasing the rate of ventilation when indoor pollutant generation rates are low or occupants are absent. After providing background information on indoor air quality and ventilation, this report provides a relatively comprehensive discussion of SBDCV. Topics covered in the report include basic principles of SBDCV, sensor technologies, technologies for controlling air flow rates, case studies of SBDCV, application of SBDCV to laboratory buildings, and research needs. SBDCV appears to be an increasingly attractive technology option. Based on the review of literature and theoretical considerations, the application of SBDCV has the potential to be cost- effective in applications with the following characteristics: (a) a single or small number of dominant pollutants, so that ventilation sufficient to control the concentration of the dominant pollutants provides effective control of all other pollutants; (b) large buildings or rooms with unpredictable temporally variable occupancy or pollutant emission; and (c) climates with high heating or cooling loads or locations with expensive energy.

Two million years ago, the cycles match the 41,000-year period of Earth's obliquity. This supports the Croll/Milankovitch theory, which attributes the cycles to variation in insolation. But for the past million years, the spectrum is dominated by a single 100,000-year feature and is a poor match to the predictions of insulation models. The spectrum can be accounted for by a theory that derives the cycles of glaciation from variations in the inclination of Earth's orbital plane.

AN - 79019774; 9169929 AB - Soluble uranyl ion [UO2(2+), U(VI)] is a kidney poison. Uranyl ion accumulates in bone, and the high specific activity uranium isotopes induce bone cancer. Although sought since the 1940's, no multidentate ligand was identified, until now, that efficiently and stably binds U(VI) at physiological pH, promotes its excretion, and reduces deposits in kidneys and bone. Ten multidentate ligands patterned after natural siderophores and composed of sulfocatechol [CAM(S)], carboxy-catechol [CAM(C)], or hydroxypyridinone [Me-3,2-HOPO] metal-binding units have been tested for in vivo chelation of U(VI). Ligands were injected intraperitoneally (i.p.) into mice 3 min after intravenous (i.v.) injection of 233U or (232+235)U as UO2Cl2 [ligand-to-metal molar ratio 75 to 92]. Regardless of backbone structure, denticity, or binding unit, all 10 ligands significantly reduced kidney U(VI) compared with controls or with mice given CaNa3-DTPA, and four CAM(S) or CAM(C) ligands also significantly reduced skeleton U(VI). Several ligands removed U(VI) from kidneys, when injected at 1 or 24 h. Injected at molar ratios > or = 300, 5-LIO(Me-3,2-HOPO) and TREN-(Me-3,2-HOPO) reduced kidney U(VI) to about 10% of control. Given orally to fasted mice at molar ratios > or = 300, those ligands significantly reduced kidney U(VI). In mice injected i.v. with 0.42 micromol kg(-1) of 235U and given 100 micromol kg(-1) of one of those Me-3,2-HOPO ligands i.p. daily for 10 d starting at 1 h after the U(VI)) loss of kidney U(VI) was greatly accelerated, and the kidneys of treated mice showed no microscopic evidence of renal injury. Crystals of uranyl chelates with linear tetradentate ligands containing bidentate Me-3,2-HOPO groups demonstrate a 1:1 structure. Considering low toxicity, effectiveness, and reasonable cost, the structurally simple linear tetradentate ligands based on the 5-LI backbone (diaminopentane) offer the most promising approach to a clinically acceptable therapeutic agent for U(VI). Work is in progress to identify the most suitable CAM or HOPO binding unit(s).

The various criteria and indicators for sustainable forest management put forth by different, institutions are critically explored. Specific types of climate change mitigation policies/projects in the forest sector are identified and examined in the light of the general, criteria for sustainable forest management. Areas of compatibility and contradiction between the climate mitigation objectives and the minimum criteria for sustainable forest management are identified and discussed. Emphasis is put on the problems of monitoring and verifying carbon benefits associated with such projects given their impacts on pre-existing policy objectives on sustainable forest, management. The implications of such policy interactions on assignment of carbon credits from forest projects under Joint Implementation/Activities Implemented Jointly initiatives are discussed. The paper concludes that a comprehensive monitoring and verification regime must include an impact assessment on the criteria covered under other agreements such as the Biodiversity and/or Desertification Conventions. The actual carbon credit assigned to a specific project should at least take into account the negative impacts on the criteria for sustainable forest management. The value of the impacts and/or the procedure to evaluate them need to be established by interested parties such as the Councils of the respective Conventions.

The paper provides background information on the technical potential for C conservation and sequestration worldwide and the average costs of achieving it. It reviews policy measures that have been successfully applied at regional and project levels toward the reduction of atmosphere greenhouse gases. It also describes both national programs and jointly implemented international activities. The monitoring methods, and the items to monitor, differ across these categories. Remote sensing is a good approach for the monitoring of C conservation, but not for C substitution, which requires estimation of the fossil fuels that would be displaced and the continued monitoring of electricity generation sources. C storage, on the other hand, includes C in products which may be traded internationally. Their monitoring will require that bi- or multi-lateral protocols be set up for this purpose.

We deployed a 24-level hydrophone array with 0.5-m level spacing down a preexisting poly vinyl chloride (PVC) cased well. Data acquisition time was quick. Only 15 multioffset shot points using a hammer-on-plate source were needed to acquire reflection data between the water table at 3 m and the bedrock at 35 m to produce a depth section image. This image extended 9 m from the receiver well, yielding resolutions between fresh-water-bearing sands and impermeable muds and clays of better than 1 m. Depth accuracy of the image was confirmed by good correlation with cone penetrometer logs. We used conventional wavefield separation and VSP-CDP mapping techniques to image the data. Tube waves, created by seismic arrivals at cross-sectional area changes in the borehole fluid column, were the primary source of coherent noise in the data. The tube-wave arrival structure was complicated by the hydrophone array, which generated and scattered tube waves at each hydrophone pod. To combat the tube wave interference, we inserted closed-cell-foam baffles between elements. The baffles attenuated and slowed the tube waves, and reduced generation and scattering. A comparison between unbaffled and baffled VSP data showed that baffling increased the maximum useful frequency from 300 Hz to over 900 Hz. By contrast, surface shot data recorded at the same site, using buried 40-Hz vertical geophones, exhibited useful frequencies of less than 250 Hz. In addition, coherent noise in surface shot records caused by air waves and first arrivals made it very difficult to identify shallow reflections above 25 m. Reflections from depths as shallow as 10 m were easy to identify in the baffled VSP data.

The hydraulic conductivity of an unconfined block of Bishop Tuff was measured over a range of near-zero matric potentials, where differences between hydraulic conductivities obtained without and with wax sealing of its lateral sides allowed isolation of film flow effects. Tensiometer and flux measurements showed that surface film flow in this system was significant for matric potentials greater (more positive) than about -250 Pa. In this range the average film thickness was shown to be potential dependent and proportional to the observed enhanced hydraulic conductivity. Measured average surface film thicknesses ranged from 2 to 70 mu m, with average film velocities in the range of 2 to 40 m d (super -1) (about 10 (super 3) times faster than that of the pore water under unit gradient saturated flow). Our experiments demonstrate that hydraulic properties of macroscopic surfaces of porous media are quantifiable, related to surface roughness, and potentially important in the flow of water in vadose environments. This study further shows that contrary to existing conceptual models, unsaturated flow in fractures cannot generally be predicted solely on the basis of aperture distribution information. The high velocities of these surface films suggest that film flow can be an important mechanism contributing to fast flow in unsaturated fractures and macropores, especially in media characterized by low-permeability matrix and along regions of convergent flow in partially saturated fractures.

The construction and performance of two versions of the "surface tensiometer," developed for determining near-zero values of matric potential on rock surfaces, are described. Laboratory surface tensiometer measurements were made on a natural fracture surface of a Bishop Tuff block equilibrated with a water table boundary set at elevations ranging from -51 to +25 mm relative to the tensiometers. All equilibrium readings were within 10 Pa of ideal values, and most were within 5 Pa. Response times associated with this instrument-rock system were in qualitative agreement with the matric potential-dependent hydraulic properties of the rock block.

The information provided by those explanatory variables is roughly equivalent to collecting an extra 12 observations per county, effectively doubling the amount of information in a typical county. Predicted county geometric means are subject to standard errors of 15% to 30% for typical counties, with the uncertainty in a given county depending on the number of radon measurements in the county and the amount of information about the geologic province that contains the county. After controlling for soil radium concentration and the effect of measuring in a basement vs. the first floor, typical geologic provinces are found to be associated with elevation or depression of indoor radon concentrations by 30% on average, with some provinces having effects of considerably larger magnitude.

Conventional sampling or borehole techniques for estimating these parameters are costly, time consuming, and invasive, all of which limit collection of hydrogeological data at a spacing needed for detailed site characterization. Incorporation of two- or three-dimensional densely sampled geophysical data with conventional hydrological data increases the amount of data available for the characterization and thus has the potential to significantly improve the hydraulic parameter estimates over those obtained from borehole data alone. The hydraulic estimation procedure can be greatly improved by incorporating dielectric information potentially available from ground penetrating radar (GPR), a noninvasive, high-resolution geophysical method. The procedures for collecting and processing GPR data in the format needed for the proposed estimation technique are relatively new and still a topic of research; our method requires as a starting point the ability to estimate dielectric constants from GPR data. Numerical experiments were performed to investigate the general utility of the GPR-assisted estimation technique under a range of conditions. Three bimodal systems were investigated, each system being composed of a sand facies together with another facies with a larger clay volume fraction; each facies was defined using characteristic values of clay content, porosity, and permeability. Using dielectric information and petrophysical relations, degree of saturation and intrinsic permeability values at each location within the three systems were identified. For bimodal systems, a dielectric constant measurement corresponds to two possible values of saturation and intrinsic permeability at each location; single values of saturation and intrinsic permeability were estimated from these values using the principle of maximum likelihood. Results from case studies demonstrate that a combination of GPR data with conventional borehole data significantly improves the estimates of saturation and has the potential to improve the estimates of permeability over those obtained from well bore data alone. The proposed method should be especially advantageous for vadose zone characterization in areas favorable for GPR data acquisition, where detailed hydraulic parameter information is required but the drilling of numerous boreholes is prohibited.

Light-colored roofs reflect more sunlight than dark roofs, so they keep buildings cooler and reduce air-conditioning demand. Typically, rooftops in the United States are dark, and thus there is a potential for saving energy and money by changing to reflective roofs. Naturally, the expected savings are higher in southern, sunny, and cloudless climates. In this study, we make quantitative estimates of reduction in peak power demand and annual cooling electricity use that would result from increasing the reflectivity of the roofs. Since light-colored roofs also reflect heat in the winter, the estimates of annual electricity savings are a net value corrected for the increased wintertime energy use. Savings estimates only include direct reduction in building energy use and do not account for the indirect benefit that would also occur from the reduction in ambient temperature, i.e. a reduction in the heat island effect. This analysis is based on simulations of building energy use, using the DOE-2 building energy simulation program. Our methodology starts with specifying 11 prototypical buildings: single- family residential (old and new), office (old and new), retail store (old and new), school (primary and secondary), health (hospital and nursing home), and grocery store. Most prototypes are simulated with two heating systems: gas furnace and heat pumps. We then perform DOE-2 simulations of the prototypical buildings, with light and dark roofs, in a variety of climates and obtain estimates of the energy use for air conditioning and heating.

AN - 85280318; pmid-9098221 AB - We compared a physiological model of 82Rb kinetics in the myocardium with two reduced-order models to determine their usefulness in assessing physiological parameters from dynamic PET data. METHODS: A three-compartment model of 82Rb in the myocardium was used to simulate kinetic PET ROI data. Simulations were generated for eight different blood-flow rates reflecting the physiological range of interest. Two reduced-order models commonly used with myocardial PET studies were fit to the simulated data, and parameters of the reduced-order models were compared with the physiological parameters. Then all three models were fit to the simulated data with noise added. Monte Carlo simulations were used to evaluate and compare the diagnostic utility of the reduced-order models. A description length criterion was used to assess goodness of fit for each model. Finally, fits to simulated data were compared with fits to actual dynamic PET data. RESULTS: Fits of the reduced-order models to the three-compartment model noise-free simulated data produced model misspecification artifacts, such as flow parameter bias and systematic variation with flow in estimates of nonflow parameters. Monte Carlo simulations showed some of the parameter estimates for the two-compartment model to be highly variable at PET noise levels. Fits to actual PET data showed similar variability. One-compartment model estimates of the flow parameter at high and low flow were separated by several s.d.s for both the simulated and the real data. With the two-compartment model, the separation was about one s.d., making it difficult to differentiate a high and a low flow in a single experiment. Fixing nonflow parameters reduced flow parameter variability in the two-compartment model and did not significantly affect variability in the one-compartment model. Goodness of fit indicated that, at realistic noise levels, both reduced-order models fit the simulated data at least as well as the three-compartment model that generated the data. CONCLUSION: The one-compartment reduced-order model of 82Rb dynamic PET data can be used effectively to compare myocardial blood-flow rates at rest and stress levels. The two-compartment model can differentiate flow only if a priori values are used for nonflow parameters.

Our objective was to develop seismic methodologies for imaging gas-filled fractures in naturally fractured gas reservoirs. The crosswell (1/4 m receiver spacing, 50 to 100 m well separation) surveys used a piezoelectric source and hydrophones before, during, and after an air injection that we designed to displace water from a fracture zone. Our intent was to increase the visibility of the fracture zone to seismic imaging and to confirm previous hydrologic data that indicated a preferred pathway. For the single well seismic imaging (a piezoelectric source and an eight-element hydrophone array at 1/4 m spacing), we also recorded data before and after the air injection. The crosswell results indicate that the air did follow a preferred pathway that was predicted by hydrologic modeling. In addition, the single well seismic imaging using vertical common depth-point (CDP) gathers indicated an anomaly consistent with the anomaly location of crosswell and hydrologic inversion results. Following the field tests, a slant well was drilled and cored to confirm the existence and nature of the rock associated with the seismic anomalies. A vertical fracture was intersected within less than 1 m of where the seismic results had predicted.

Water compositions are generally consistent with a diagenetically altered seawater combined with dilute meteoric water. Stevens and deeper fluids are generally Na-enriched at the expense of Ca which may suggest dissolution by organic acids. The exceptions are the Ca- and Br-enriched waters of the Shallow Oil Zone. Br concentrations show a general decrease deeper in the fields. The Shallow Oil Zone and the deeper Point of Rocks/Phacoides waters establish two endmembers with most samples confined to a rapidly changing mixing zone within the Miocene Stevens (NPR#1) and the Antelope (Cymric) Formations. The Br enrichments may be the results of (1) seawater evaporated to halite precipitation followed by dilution, (2) membrane filtration, or (3) a chemical affinity between Br and organics like that observed for I. Rare gas measurements show the highest Xe enrichments ever measured in natural fluids. Xe enrichments dominate the gases of the Shallow Oil Zone and decrease deeper in the section along a mixing line with a typical air saturated water of the Phacoides/Pt of Rocks. There is also a three component mixing relation for F (super Xe) vs. F (super He) among the Shallow Oil Zone (high F (super Xe) ), the Antelope Shale (high F (super He) ) and the Phacoides/Pt of Rocks (low F (super Xe) and F (super He) ). The Antelope Shale samples suggest a U-rich shale member. The Phacoides/Pt of Rocks samples contain a component of mantel He.

AN - 78908944; 9098552 AB - The tracer 6-[18F]fluoro-L-m-tyrosine (FMT) was studied with regard to its biochemistry and kinetics, as well as its utility in evaluating brain dopaminergic function in primates before and after 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) treatment using positron emission tomography (PET). Plasma analysis of FMT and its F18-labeled metabolites 6-fluoro-3-hydroxyphenylacetic acid (FPAC) and 6-fluoro-3-hydroxyphenylethylamine (FMA) during PET scanning enabled kinetic analysis of FMT uptake. A separate study examined brain FMT metabolism in MPTP-naive monkeys euthanized 60 or 120 min after FMT injection. Almost 60% of total plasma F-18 activity was associated with FPAC and FMA 120 min after FMT injection. The FMT signal accumulated preferentially in dopaminergic areas such as caudate and putamen. This bilateral FMT signal was disrupted after unilateral intracarotid artery (ICA) MPTP infusion which reduced ipsilateral striatal activity. A three compartment three kinetic rate constant model for FMT uptake revealed reduced FMT decarboxylation (k3) in ipsilateral caudate and putamen after unilateral MPTP although a further decrease was not evident after intravenous MPTP. FPAC was the major F-18 species in all brain regions except in cerebellum where FMT was predominant 60 min post-mortem. FPAC was most concentrated in dopaminergic areas whereas lower levels occurred in areas containing few dopamine terminals. These data demonstrate preferential FMT metabolism and F-18 retention in dopaminergic tissue and support the use of FMT to evaluate normal and abnormal dopaminergic function.

If the ground is sufficiently resistive ground penetrating radar (GPR) may be used and its interpretation usually relies on high frequency, wave field, representation in which pulse transit time is measured and dielectric properties are recovered. We have investigated the use of EM fields of intermediate frequency range, 1 to 100 MHz, where both diffusion and wave fields must be considered and new measurement strategies must be used to recover both conductivity and electric permittivity from the data. We have chosen to analyze the ground response at these intermediate frequencies by way of the surface impedance for plane waves. At these frequencies impedance measurements require scaling up the magnetic field sensors used for low frequency EM and scaling down the dipole antennas used in radar. The impedance has a distinct advantage in that coupling to the source is unnecessary, and the source can always be positioned far enough away to yield plane waves at the receiver. This in turn permits the use of a wide range of fairly standard imaging codes for interpreting the result. The high-frequency EM impedance is shown to be very sensitive to ground electrical properties and strongly dependent on the angle of incidence. In this paper we demonstrate methods for evaluating the incident angle, correcting the impedance data for normal incidence, and finally imaging the electrical conductivity and permittivity of simple layered earth models.

The Idaho National Laboratory (INEL) Cold Test Pit (CTP) has been carefully constructed to simulate stored hazardous waste occurrences. IP and resistivity surveys of the CTP show a very strong IP response and a modest resistivity response associated with the simulated waste. Several false positive resistivity anomalies are noted. 2-D inversion of the data accurately determine the lateral limits of the waste zone. The depth of burial indicated is deeper than reported by the construction engineers. Limited depth extent is recognized, in distinction to results from other, resistivity-based, methods, but it also appears too deep. IP holds promise as a method for locating buried waste.

Eleven distinct EM systems, covering the geophysical spectrum, acquired data on a grid over the Idaho National Engineering Laboratory (INEL) Cold Test Pit (CTP). The systems are investigated and evaluated for the purpose of identifying and reviewing existing geophysical characterization instrumentation (commercial and experimental), integrating those technologies with multi-dimensional interpretational algorithms, and identifying gaps in shallow subsurface EM imaging technology. The EMID data, are valuable for testing and evaluating new interpretational software, and developing techniques for integrating multiple datasets. The experimental field techniques shows how the acquisition of data in a variety of array configurations can considerably enhance interpretation. All data are available on the world wide web (http://vetem.lbl.gov). Educators and students are encouraged to use the data for both classroom and graduate studies. The purpose of this paper is to explain why, where, how and what kind of data were collected. It is left to the reader to assess the value of a given system for their particular application. Information about the EMID is organized into two general categories: survey description and system evaluation.

AN - 78806345; 9003707 AB - New ligands for in vivo chelation of Pu(IV) are being synthesized and evaluated in mice for efficacy and toxicity. Biokinetic studies of the new ligands, CaNa3-DTPA, and Pu(IV) are major components of those investigations. Young adult female mice were injected intravenously (iv) with 3H-inulin, 14C-CaNa3-DTPA, or 238Pu(IV) citrate to provide baseline data for plasma clearance, tissue uptake, and excretion rates and to determine the dilution volume (VOD) and renal clearance rate (RC) of filterable substances. Published plasma clearance data for iv-injected 14C-CaNa3-DTPA and Pu(IV) citrate in Reference Man, dog, and rat were collected. Based on combined data for 3H-inulin and 14C-CaNa3-DTPA, VOD = 17% of body weight and RC = 18 mL kg(-1) min(-1) for mice. Retention of 14C-CaNa3-DTPA in the four species is proportional to body weight and inversely proportional to RC: Integrals of the retention of 14C-CaNa3-DTPA from R(t) = 1.0 to R(t) = 0.05 are 108, 43, 28, and 10 DF min, respectively, for Reference Man, dog, rat, and mouse. Clearances of iv-injected Pu(IV) citrate from plasma are in the same order: The plasma curve integrals from injection to 1440 min are 840, 640, 280, and 67 DF min, respectively, for Reference Man, dog, rat, and mouse. In mice, a large fraction of newly injected Pu(IV) is rapidly transferred to the interstitial water of bulk soft tissue (excluding liver and kidneys), from which it is cleared at the same rate as from the plasma. Rapid plasma clearance, escape into interstitial water (22%ID at 20 min), significant early urinary excretion (8%ID in 12 h), and prompt deposition in liver and skeleton (complete in 12 h) are evidence of inefficient binding to plasma protein (mainly transferrin) of newly injected Pu(IV) in mice. Conversely, slow plasma clearance, little early urinary excretion, and delayed deposition in liver and skeleton reflect more efficient binding by transferrin of newly injected Pu(IV) in Reference Man and dog. Pharmacokinetic parameters (effective dosage, effective concentration) of CaNa3-DTPA, alone or combined with plasma Pu(IV) integrals, yielded only qualitative predictions of the relative efficacies of CaNa3-DTPA therapy in four species. The need for improved models of Pu(IV) and ligand biokinetics and the suitability of the three animals for predicting chelation therapy outcomes in humans are discussed.

This method is based on an algorithm related to the Hough transform which is modified to find sinusoidal rather than linear patterns. The algorithm uses the high-intensity contrast between the fracture aperture and the rock wall, as well as the sinusoidal trajectory defined by the intersection of the borehole and the fracture. The analysis rate of the algorithm itself is independent of fracture contrast and network complexity. The method has successfully identified fractures both in test cases containing several fractures in a noisy background and in real borehole images. The analysis rate was 0.3-1.2 minutes/m of input data, compared to an average of 12 minutes/m using an existing interactive method. An automatic version under development should open new possibilities for site characterization, such as real-time exploration and analysis of tunnel stability and support requirements as construction proceeds.

AN - 85264623; pmid-9015815 AB - A comparison is made between two methods of parameter estimation for analysis of dynamic experiments in which the input function is noisy. Noise in the input function leads to uncertainties in the calculated model-predicted values, and therefore the covariance matrix of the residuals is a function of the model parameters. Statistical uncertainties in the model-predicted values significantly change the nature of the fitting process and the quality of the results. The initial method uses a weighted least-squares criterion where the weighting matrix is the inverse of the full covariance matrix of the residuals, incorporating both the noise in the output data and the noise in the input function. The methodology was applied to dynamic emission tomography studies of the heart, where the blood (input) and tissue (output) tracer concentrations at each time are derived from two regions of interest in the same tomographic section. The second method introduces additional parameters to describe the input function, and adds terms to the weighted sum of squares which comprise the criterion. Instead of only summing the weighted terms to account for differences between the model and the output function, there is a second set of terms to account for the differences between the model and the input function. The two methods have different theoretical bases and appear to optimize different criteria, but it is shown here that they are equivalent to one another. The criterion which they minimize is the same under certain matrix invertibility constraints, which must be satisfied to ensure the stability of either method.

AN - 79425584; 9383244 AB - We have previously reported that environmental-level magnetic fields (1.2 microT [12 milligauss], 60 Hz) block the growth inhibition of the hormone melatonin (10(-9) M) on MCF-7 human breast cancer cells in vitro. We now report that the same 1.2 microT, 60 Hz magnetic fields significantly block the growth inhibitory action of pharmacological levels of tamoxifen (10(-7) M). In biophysical studies we have taken advantage of Faraday's Law of Current Induction and tested whether the 1.2 microT magnetic field or the associated induced electric field is responsible for this field effect on melatonin and tamoxifen. We observe that the magnetic field component is associated with the field blocking effect on melatonin and tamoxifen function. To our knowledge the tamoxifen studies represent the first experimental evidence for an environmental-level magnetic field modification of drug interaction with human breast cancer cells. Together, these findings provide support to the theory that environmental-level magnetic fields can act to modify the action of a drug or hormone on regulation of cell proliferation. Melatonin and tamoxifen may act through different biological pathways to down-regulate cell growth, and further studies are required to identify a specific biological site of interaction for the 1.2 microT magnetic field.

AN - 79107884; 9214581 AB - Low-molecular weight antioxidants in rat peritoneal neutrophils undergo rapid redox recycling, so measurements were made of their initial content and subsequent changes during the respiratory burst, when superoxide formation is maximized. Endogenous vitamin E, ascorbate and total glutathione (reduced + oxidized) were not significantly changed during 30 min of respiratory burst, which was stimulated by phorbol 12-myristate 13-acetate (PMA). When de novo synthesis of glutathione was inhibited by buthionine-[S,R] sulfoximine (BSO), the glutathione content rapidly decreased in activated neutrophils but not in resting cells. The lost total glutathione was recovered neither from the incubation medium nor as a protein-bound form, which suggests that irreversible oxidation of glutathione occurs. Furthermore, the glutathione loss continues even 30 min after PMA stimulation, when the respiratory burst has almost ceased. The decrease of glutathione was prevented by added catalase, or by addition of NaN3 or KCN which inhibits myeloperoxidase (MPO). Superoxide dismutase had no protective effects. These findings suggest the involvement of an MPO-H2O2-halide system in the accelerated consumption of glutathione during the respiratory burst. Additional studies showed that neutrophil-derived chloramines found in the extracellular medium could lead to intracellular glutathione loss. Incubation of resting cells with chemically produced membrane permeable monochloramine in the presence of BSO resulted in a decrease of glutathione, whereas membrane-impermeable taurine-chloramine was less effective. We conclude that chloramines are responsible for accelerated glutathione turnover in neutrophils during the respiratory burst. Permeable extracellular chloramines derived from the respiratory burst activity, such as monochloramine, can reenter cells and react with thiols.

Our simple model is based on the assumption of an infinitely long uniform casing embedded in a homogenous full space. Nevertheless the results indicate that if the pipe characteristics are independently known then the formation signal can be accurately recovered. This is best done at a single frequency where the pipe attenuation is modest. In fact we show that the optimal frequency for formation signal recovery is defined mainly by the pipe parameters and is largely independent of the formation conductivity.

The displacement-discontinuity boundary conditions were used to model the fractures explicitly. The effect of fracture spacing on the wavefield generated by an explosion source was examined by changing the spacing from 0.6 to 0.15 of a wavelength. A wavefield was computed for a transversely anisotropic (TI) medium with elastic moduli equivalent to the effective static moduli of the most densely fractured system. The results showed significant differences between the amplitudes, velocities, and frequency content of the waves in the explicit and equivalent medium fracture models. These differences result from frequency-dependent time delays and filtering across each fracture and channeling along fractures that are not included in the zero-frequency effective medium description. These effects lead to an unusually strong velocity and amplitude anisotropy which cannot explained by the TI medium approximation. The characterization may prove useful in characterizing fractures in reservoir rock.

The ODD method divides a large domain into several small overlapping subdomains. The method allows the exchange of waves between the subdomains through the overlapping regions without the need for any internal interface connecting conditions. For each subdomain, calculations are performed independently. Thus, it is possible to use different numerical algorithms in each subdomain. The method not only saves computing time, but also gives nearly the same accuracy as conventional methods. This paper describes the ODD algorithm when wave propagation in the subdomains are computed using the finite difference and the pseudospectral methods. An example of the method for a two-dimensional domain divided into 25 subdomains demonstrates the computing efficiency and flexibility of the ODD method.

Our high-resolution studies (chemical elements, delta (super 13) C, delta (super 18) O, calcareous nannofossils, planktonic and benthic foraminifera) show that below the marl-clay transition there is a 40-50cm thick interval (corresponding to 10-20 kyr) containing a detailed record of a gradual succession of faunal and geochemical events culminating in the benthic extinctions. Planktonic foraminiferal and nannofossil changes (e.g., the onset of demise in Fasciculithus genus) occur a few meters below the marl-clay transition. In the limestone 50cm below the base of the clay, a prominent glauconite maximum indicates that sea-floor oxygenation suddenly decreased. Glauconite continues to be common until the onset of clay deposition. A whole-rock negative delta (super 13) C shift (1.6), most likely reflecting an original sea-water trend, is gradually developed over the 40cm of greenish brown marls immediately below the clay. At the base of these marls there is a small, significant iridium anomaly of 133 ppt Ir compared with an average background of 38 ppt. In the marls the demise of the Fasciculithus species accelerates, Gavelinella beccariiformis becomes extinct, and the abundance of Acarinina species begins to increase. The superjacent 4m of clay is devoid of original calcite in its lower part and has a low calcareous content higher up. At calcareous levels in the clay an unusual planktonic foraminifera fauna occurs, dominated by Acarinina species. When marl deposition returns, delta (super 13) C gradually increases and then stabilizes at values about 0.5 lower than before the isotopic excursion. The delta (super 13) C excursion spans in total 5m, probably corresponding to 200-400 kyr. The fasciculiths disappear shortly after the stabilization of delta (super 13) C. Here we also present a whole-rock delta (super 13) C profile through the entire Paleocene section at Zumaya. The profile is very similar to previous profiles registered in well preserved deep-sea material, suggesting that whole-rock delta (super 13) C at Zumaya can be used for correlation. The origin of the Ir anomaly nearly equal 40cm below the benthic extinction event is enigmatic. It may be impact-related; however, the clearly gradual sequence of environmental events in the 50cm below the dissolution clay, are more readily reconciled with changing oceanic circulation and palaeogeographic change, possibly in connection with volcanism, than with an instantaneous impact. The small Ir anomaly may reflect such volcanism, sea-water precipitates, or a small impact event, possibly unrelated to the palaeoenvironmental change.

The Sr, Nd and trace element compositions of basalts erupted over the past 20 Ma in the Basin and Range indicate that the magmas were melted from varying proportions of lithospheric and asthenospheric mantle. Helium, neon and argon isotopes were measured in these basalts to characterize the noble gas isotopic characteristics of lithospheric mantle. There is a substantial range of helium R/Ra values observed (3.0 to 7.8), and these values correlate roughly with Nd and Sr isotopic ratios. Basalts from eastern California and western Nevada have relatively high R/Ra values of 5.5 to 7.8 and a restricted variation in Sr and Nd isotopes. Basalts from southern Nevada and eastern Arizona have lower R/Ra values (3.0 to 6.3) and a wider range in Nd and Sr isotopic ratios. We infer that the lithosphere beneath eastern California (the Eastern Sierra Province, or ESP) has a similar He/Nd ratio to that of depleted mantle. The lithosphere beneath the east-central Basin and Range (ECBR) has a higher He/Nd ratio than depleted mantle. The differing noble gas contents and isotopic signatures of the two lithospheric provinces may be a consequence of differences in age, but may also reflect more extensive degassing west of the cratonal margin due to extensive Mesozoic and younger volcanism. It has been proposed that a major source of volatiles in extensional basins is infiltration of small-degree melts from the convecting mantle into the lithosphere; however, the lack of MORB-like helium isotopic signatures in these basalts and the radiogenic nature of the lithospheric mantle noble gases suggests that this model is incorrect for the southwestern U.S. The lack of helium isotopic signatures higher than MORB supports the prevailing wisdom that such signatures are uniquely associated with mantle plumes containing volatiles from the lower mantle rather than a helium-3 rich mantle lithosphere.

The test was carried out by ponding water in a 6.5 Acre basin (diameter about 200 m) for about one month. Several conservative and non-conservative tracers were added to the water after one week of the test. The distribution of tracers was monitored using gamma logging (used to detect the gamma-emitted radioactive tracers), and suction lysimeters (used to collect water samples). It was determined that flow through vertical fractures was the major component of flow, significantly exceeding the lateral movement of water. Data analysis using one-dimensional advective-dispersive transport model showed that the tracer breakthrough curves (BTCs) cannot be forced into this conventional model, because this model cannot describe the spatial variations in tracer movement that occur within the fracture system. For example, tracers that were applied one week after the beginning of the test did not always follow the same pathways as the initial water movement. In order to study the spatial and temporal distribution of tracer in the subsurface, we prepared a three-dimensional visualization of results showing the arrival time and types of breakthrough curves for different locations. A physical explanation for different types of BTCs is given using a set of diagrams illustrating the fundamental geometric components of fracture patterns. Based on this analysis, we believe that a conceptual model of the tracer transport should include multiple fast paths, which allow abrupt transitions in the BTCs. To simulate tracer movement in fractured basalt, a compartment model based on a series of exponential functions is being developed. The results of this work will be used to help develop a dynamic-chaotic model of flow in fractured basalt.

Chloride concentrations in infiltrating water were calculated from areal distributions of precipitation and infiltration for the current climatic conditions and for the last glacial maximum, combined with measured chloride concentrations in precipitation, and estimated surface fluxes. This study suggests that the calculated mean current infiltration rate ( approximately 4.9 mm/year) is probably a maximum value for the Yucca Mountain site, and it may be as low as 1 mm/year. Analysis of the chloride data and three-dimensional modeling showed that waters from the last glacial maximum or prior could be present in the Paintbrush bedded tuffs, and in the underlying Topopah Spring welded tuffs, predominately under regions of thick alluvium having little infiltration. Model results are roughly similar to variations in pore salt chloride from the Exploratory Studies Facility tunnel, indicating predominantly vertical flow under high and low infiltration regions. At greater depths, there is significant mixing due to lateral flow in the Calico Hills Unit. Perched water chloride concentrations are closely matched using the calculated conditions for the last glacial maximum. This work has significant implications for the interpretation of "bomb-pulse" Cl-36/Cl ratios, which may be strongly masked by high chloride concentrations around faults that intersect low-lying regions of thick alluvium. This result has since been supported by the finding of "bomb-pulse" tritium in the tunnel at the Ghost Dance Fault, where no bomb-pulse Cl-36/Cl ratios were found.

This study complements laboratory experiments, underground heater tests, and simulations to better understand the effect of repository heat on coupled chemical-hydrological processes and the attendant consequences to repository performance of reduced or enhanced fracture permeability, as time- and temperature-dependent mineralogical changes will occur while fluid movement takes place at elevated temperatures for thousands of years.Because fracture flow is the dominant flow regime in the TSw, the focus of attention is on alteration around and within fractures. Complex fracture networks within the TSw are either sub-horizontal or steeply inclined. Sub-horizontal fractures consist of a silica polymorph (cristobalite?), are coated by a <.1 mm thick sheet of Fe/Mn oxides, are virtually healed, and are surrounded by a 2-10 cm bleached zone consisting of a silica polymorph with felted texture. A second fracture set of later generation cuts the sub-horizontal set, generally strikes N-S, and usually dips at a high angle. These fractures are generally filled with cristobalite, calcite, quartz, potassium-feldspar and a barium-rich phase. Alteration around high-angle fractures is less than around the sub-horizontal set. High-angle fracture-filling features vary in thickness from <1-10 mm, with openings ranging from vuggy regions 1 cm across to regions that are completely healed. Drift-scale heater test simulations suggest that fluid flow rates under repository heating will be orders of magnitude higher (1000s of m (super 3) /m (super 2) /year) than in the past (11 Ma) hydrothermal system. Calcite should be mobilized in amounts sufficient to see new overgrowths on pre-existing calcites. Overall, secondary minerals would be the same: carbonates, clays, zeolites, and silica polymorphs. An increase in permeability is shown near the drift, with no regions of reduced permeability. Regions that are opened up are those that have quickly been brought into contact with boiling-zone condensate. Sealed regions could be expected where condensate flow is long and saturation of secondary mineral phases is reached under cooler conditions (40-60 degrees C). Laboratory experiments mimicking the same heater test conditions corroborate that secondary mineral assemblages will be texturally different from the present, with more calcite-rich clinoptilolites intimately intergrown with mixed-layer illite/smectite clays. Mapping of mineralogical heterogeneity permits identification of candidate areas where alteration will take place, and will serve as the basis of sensitivity studies to determine the scale at which heterogeneity needs to be represented to predict behavior of the system.

The form of convection in the liquid-dominated Salton Sea Geothermal System (SSGS), California, has been hypothesized to consist of layered convection cells. Such flow patterns have been observed in thermohaline convection in viscous liquid systems such as the oceans. However, additional flow processes arise in porous media systems due to the presence of the solid matrix. These processes include thermal retardation, hydrodynamic dispersion, and viscous drag due to permeability effects. We have developed a simple model for brine density that takes into account the effects of dissolved sodium chloride and calcium chloride as well as temperature on liquid density. We use this density model in the TOUGH2 simulator to study thermohaline convection in a system modeled after the SSGS. TOUGH2 uses the integral finite difference method with residual formulation and fully coupled solution technique for solving the strongly coupled equations governing thermohaline convection in porous media. Our simulations show the general dynamics of porous media thermohaline convection in a liquid-dominated geothermal system, and the effects of porosity and permeability in particular. In thermohaline convection, enhanced transport of brine over heat in low porosity regions cannot occur because buoyancy caused by heat and brine together drive the flow. In the case of permeability anisotropy, layered thermohaline convection can persist for more than one million years provided the vertical permeability is smaller than the horizontal permeability. Layered thermohaline convection inhibits mixing and can explain many of the observations made at the Salton Sea Geothermal System over the years.

During early diagenesis and dewatering processes anoxic conditions are maintained by bacterial action. However, the geologic record abounds with examples of clearly oxic mineral assemblages in metapelites (hematite and magnetite bearing rocks). Indeed, even typically reduced sulfide+graphite-bearing metapelites exhibit f(O (sub 2) ) values close to the QFM buffer. Such "oxic" assemblages are found in closed-system metamorphic rocks with no evidence of further modification of bulk chemistry other than loss of H (sub 2) O and CO (sub 2) in response to changes of temperature and pressure. Such oxic metamorphic assemblages may be contrasted with "anoxic" metamorphic assemblages which are generally graphite-rich and also pyrite- or pyrrhotite-rich. In general, these are also characterized by a distinct suite of elements such as V, Zn which are associated in modern environments with organic-rich shales.Apparently, between sedimentation and metamorphism routinely anoxic sedimentary conditions are changed such that the metamorphosed equivalents are seemingly oxic. We propose by means of appropriate phase diagrams, to illustrate the various pathways by which these seemingly conflicting conditions may be produced by combinations of pH, temperature, and pressure. This type of analysis may be geologically useful both for discerning and reconstructing subduction histories as well as deducing initial paleo-oceanographic conditions from metamorphic rocks.

It has previously been shown in the chemical engineering literature that CH (sub 4) hydrate stability conditions in electrolyte solutions are related to the activity of water (a (sub w) ). Here we present additional experimental data in support of this relationship and then use the relationship to address issues relevant to geophysicists. Pressure and temperature conditions of CH (sub 4) hydrate dissociation were determined for 10 solutions containing variable concentrations of Cl (super -) , SO (sub 4) (super 2-) Br (super -) , Na (super +) , K (super +) , Mg (super 2+) , NH (sub 4) (super +) , and Cu (super 2+) . The reciprocal temperature offset of CH (sub 4) hydrate dissociation between the CH (sub 4) -pure water system and each of these solutions (and for other electrolyte solutions in literature) is directly related to the logarithm of the activity of water (lna (sub w) ). Stability conditions for CH (sub 4) hydrate in any pore water system therefore can be predicted simply and accurately by calculating lna (sub w) . The effect of salinity variation and chemical diagenesis on CH (sub 4) hydrate stability conditions in the marine environment can be evaluated by determining how these processes affect lna (sub w) of pore water.

Rapid exchange reactions buffer the groundwater isotope ratios, and a two-stage evolution is observed. After a perturbation in the system an exchange front, which can be described by a retardation equation, propagates through the system at a velocity equal to the groundwater velocity divided by a retardation factor. If steady boundary conditions are maintained, the exchange front is advected out of the system and a quasi-steady state develops in which dissolution reactions influence the isotope ratios but the exchange reactions have no effect. Because clay minerals which readily exchange ions or water molecules with groundwater are found in most hydrologic systems, exchange reactions may significantly affect interpretation of isotopic data.

Lawrence Berkeley National Laboratory and were used to constrain flow velocities and search for preferential flow paths. In the Orinda formation siltstone, (super 87) Sr/ (super 86) Sr increases strongly over tens of meters along presumed flow paths, indicating slow groundwater flow. Dissolved Sr is close to isotopic equilibrium with the exchangeable Sr in the clays, and the observed (super 87) Sr/ (super 86) Sr increase is interpreted as a cation exchange front moving slowly through the unit combined with dissolution of minerals with relatively high (super 87) Sr/ (super 86) Sr ratios. The data are inverted using a one-dimensional transport-dissolution-exchange model; the results indicate long-term average flow velocities of less than 0.2 m/yr which are consistent with (super 14) C measurements. The data suggest a lack of strong preferential flow paths through this unit. Copyright 1997 by the American Geophysical Union.

Proton translocation by bacteriorhodopsin (bR), the light-driven proton pump in Halobacterium salinarium, involves this kind of a change in the accessibility of the centrally located retinal Schiff base. This key event in bR's photocycle ensures that proton release occurs to the extracellular side and proton uptake from the cytoplasmic side. To study the role of protein conformational changes in this reprotonation switch, spin labels were attached to pairs of engineered cysteine residues in the cytoplasmic interhelical loops of bR. Light-induced changes in the distance between a spin label on the EF interhelical loop and a label on either the AB or the CD interhelical loop were observed, and the changes were monitored following photoactivation with time-resolved electron paramagnetic resonance (EPR) spectroscopy. Both distances increase transiently by about 5 angstrom during the photocycle. This opening occurs between proton release and uptake, and may be the conformational switch that changes the accessibility of the retinal Schiff base to the cytoplasmic surface after proton release to the extracellular side.

The N-terminal domain of NtrC, which acts positively on the remainder of the protein, is homologous to a large family of signal transduction domains called receiver domains. Phosphorylation of an aspartate residue in a receiver domain modulates the function of a downstream target, but the accompanying structural changes are not clear. In the present work we examine structural and functional differences between the wild-type receiver domain of NtrC and mutant forms carrying constitutively activating substitutions. Combinations of such substitutions resulted in both increased structural changes in the N-terminal domain, monitored by NMR chemical shift differences, and increased transcriptional activation by the full-length protein. Structural changes caused by substitutions outside the active site (D86N and A89T) were not only local but extended over a substantial portion of the N-terminal domain including the region from alpha -helix 3 to beta -strand 5 ("3445 face") and propagating to the active site. Interestingly, the activating substitution of glutamate for aspartate at the site of phosphorylation (D54E) also triggered structural changes in the 3445 face. Thus, the active site and the 3445 face appear to interact.

In such cases, simultaneous measurement of carbon-14 helps to determine sources. The method was applied at a petrol station where hydrocarbons were the only source of carbon-14 free carbon. Both delta carbon-13 and carbon-14 were measured in soil gas carbon dioxide and inorganic carbon dissolved in the groundwater. Low carbon-14 concentrations and high delta carbon-13 established that the soil gas carbon dioxide derived from methanogenesis of hydrocarbons and not from the dissolution of the shells of marine organisms which were prevalent at the site. Additionally, low carbon-14 content linked with a 16 ppt drop in delta carbon-13 values in the carbon dioxide across a semipermeable layer beneath the station building confirmed that microbial oxidation of methane was occurring within this zone.

A pilot-scale demonstration was carried out in a shallow catchment basin at the Savannah river site contaminated by radionuclides. Colloidal silica was used as the barrier liquid, producing a chemically benign, nearly impermeable barrier through a large increase in viscosity following injection into the subsurface. The simulations showed that it might be difficult to inject significant quantities of gel over a practical time frame into low-permeability formations. Higher injection rates might be possible in conditions where there was anisotropic or heterogeneous permeability.

AN - 78652312; 9118927 AB - In assessing the distribution and metabolism of toxic compounds in the body, measurements are not always feasible for ethical or technical reasons. Computer modeling offers a reasonable alternative, but the variability and complexity of biological systems pose unique challenges in model building and adjustment. Recent tools from population pharmacokinetics, Bayesian statistical inference, and physiological modeling can be brought together to solve these problems. As an example, we modeled the distribution and metabolism of benzene in humans. We derive statistical distributions for the parameters of a physiological model of benzene, on the basis of existing data. The model adequately fits both prior physiological information and experimental data. An estimate of the relationship between benzene exposure (up to 10 ppm) and fraction metabolized in the bone marrow is obtained and is shown to be linear for the subjects studied. Our median population estimate for the fraction of benzene metabolized, independent of exposure levels, is 52% (90% confidence interval, 47-67%). At levels approaching occupational inhalation exposure (continuous 1 ppm exposure), the estimated quantity metabolized in the bone marrow ranges from 2 to 40 mg/day.

AN - 78541827; 8919076 AB - Past efforts to identify areas with higher than average indoor radon concentrations by examining the statistical relationship between local mean concentrations and physical parameters such as the soil radium concentration have been hampered by the variation in local means caused by the small number of homes monitored in most areas. In this paper, indoor radon data from a survey in Minnesota are analyzed to minimize the effect of finite sample size within counties, to determine the true county-to-county variation of indoor radon concentrations in the state, and to find the extent to which this variation is explained by the variation in surficial radium concentration among counties. The analysis uses hierarchical modeling, in which some parameters of interest (such as county geometric mean radon concentrations) are assumed to be drawn from a single population, for which the distributional parameters are estimated from the data. Extensions of this technique, known as random effects regression and mixed effects regression, are used to determine the relationship between predictive variables and indoor radon concentrations; the results are used to refine the predictions of each county's radon levels, resulting in a great decrease in uncertainty. The true county-to-county variation of geometric mean radon levels is found to be substantially less than the county-to-county variation of the observed geometric means, much of which is due to the small sample size in each county. The variation in the logarithm of surficial radium content is shown to explain approximately 80% of the variation of the logarithm of geometric mean radon concentration among counties. The influences of housing and measurement factors, such as whether the monitored home has a basement and whether the measurement was made in a basement, are also discussed. The statistical method can be used to predict mean radon concentrations, or applied to other geographically distributed environmental parameters.

In the multiplicative approach, the rat model parameters are multiplied by the ratio of the mean values between humans and rats. Additive scaling of the distributions is defined by adding the difference between the average human value and the average rat value to each rat value. Finally, allometric scaling relies on established extrapolation relationships using power functions of body weight. A physiologically-based pharmacokinetic model was fitted independently to rat and human benzene disposition data. Human model parameters obtained by extrapolation and by fitting were used to predict the total bone marrow exposure to benzene and the quantity of metabolites produced in bone marrow. We found that extrapolations poorly predict the human data relative to the human model. In addition, the prediction performance depends largely on the quantity of interest. The extrapolated models underpredict bone marrow exposure to benzene relative to the human model. Yet, predictions of the quantity of metabolite produced in bone marrow are closer to the human model predictions. These results indicate that the multiplicative and allometric techniques were able to extrapolate the model parameter distributions, but also that rats do not provide a good kinetic model of benzene disposition in humans.

AN - 78572861; 8943004 AB - The major human apurinic/apyrimidinic (AP) endonuclease (class II) is known to cleave DNA 5' adjacent to an AP site, which is probably the most common DNA damage produced hydrolytically or by glycosylase-mediated removal of modified bases. p-Benzoquinone (pBQ), one of the major benzene metabolites, reacts with DNA to form bulky exocyclic adducts. Herein we report that the human AP endonuclease directly catalyzes incision in a defined oligonucleotide containing 3,N4-benzetheno-2'-deoxycytidine (pBQ-dC) without prior generation of an AP site. The enzyme incises the oligonucleotide 5' to the adduct and generates 3'-hydroxyl and 5'-phosphoryl termini but leaves the pBQ-dC on the 5' terminus of the cleavage fragment. The AP function of the enzyme is not involved in this action, as no preexisting AP site is present nor is a DNA glycosylase activity involved. Nicking of the pBQ-dC adduct also leads to the same "dangling base" cleavage when two Escherichia coli enzymes, exonuclease III and endonuclease IV, are used. Our finding of this unusual mode of action used by both human and bacterial AP endonucleases raises important questions regarding the requirements for substrate recognition and catalytic active site(s) for this essential cellular repair enzyme. We believe this to be the first instance of the presence of a bulky carcinogen adduct leading to this unusual mode of action.

AN - 78591489; 8947529 AB - Induction of DNA double-strand breaks (dsbs) in mammalian cells is dependent on the spatial distribution of energy deposition from the ionizing radiation. For high LET particle radiations the primary ionization sites occur in a correlated manner along the track of the particles, while for X-rays these sites are much more randomly distributed throughout the volume of the cell. It can therefore be expected that the distribution of dsbs linearly along the DNA molecule also varies with the type of radiation and the ionization density. Using pulsed-field gel and conventional gel techniques, we measured the size distribution of DNA molecules from irradiated human fibroblasts in the total range of 0.1 kbp-10 Mbp for X-rays and high LET particles (N ions, 97 keV/microns and Fe ions, 150 keV/microns). On a mega base pair scale we applied conventional pulsed-field gel electrophoresis techniques such as measurement of the fraction of DNA released from the well (FAR) and measurement of breakage within a specific NotI restriction fragment (hybridization assay). The induction rate for widely spaced breaks was found to decrease with LET. However, when the entire distribution of radiation-induced fragments was analysed, we detected an excess of fragments with sizes below about 200 kbp for the particles compared with X-irradiation. X-rays are thus more effective than high LET radiations in producing large DNA fragments but less effective in the production of smaller fragments. We determined the total induction rate of dsbs for the three radiations based on a quantitative analysis of all the measured radiation-induced fragments and found that the high LET particles were more efficient than X-rays at inducing dsbs, indicating an increasing total efficiency with LET. Conventional assays that are based only on the measurement of large fragments are therefore misleading when determining total dsb induction rates of high LET particles. The possible biological significance of this non-randomness for dsb induction is discussed.

The demonstration site was Retention Basin 281-3H, a shallow catchment basin at the Savannah River Site, which is contaminated mainly by radionuclides ( (super 137) Cs, (super 90) Sr, and (super 238) Pu). The goals of the field demonstration were (a) to demonstrate the ability to create a continuous subsurface barrier in order to isolate the contaminants, and (b) to demonstrate the continuity, performance, and integrity of the barrier. The site was characterized, and preliminary hydraulic conductivity data were obtained from core samples. Based on the site characteristics and the functional requirements, a conceptual model was developed, the barrier specifications were defined, and lance injection was selected as the emplacement method. The injection strategy for the subsurface conditions at the site was determined using numerical simulations. An appropriate variant of Colloidal Silica (CS) was selected as the barrier liquid based on its relative insensitivity to interactions with the site soils, and the formulation for optimum site performance was determined. A barrier verification strategy, including hydraulic, pneumatic, tracer, and geophysical methods, was developed. A lance water injection test was conducted in order to obtain representative estimates of the hydraulic conductivity and its distribution for the design of the barrier emplacement. The water injection test demonstrated the lack of permeable zones for CS injection, and a decision not to proceed with the barrier emplacement was reached.

AN - 78448816; 8875987 AB - Bcl-2 appears to contribute to neoplasia primarily by promoting cell survival, rather than by stimulating cellular proliferation. Bcl-2, and the related protein Bcl-xL, each suppress apoptosis induced by a wide variety of stimuli in many different cell types. Here we report that suppression of apoptosis by Bcl-2 or Bcl-xL markedly elevates the levels of radiation-induced mutations. This enhanced mutagenesis is the result of an increase in mutation frequency (mutations per survivor) together with a moderate increase in viability. Ectopic expression of either Bcl-2 or Bcl-xL enhances radiation mutagenesis in cells with wtp53. Surprisingly, we found that ectopic expression of Bcl-xL also promotes mutagenesis in p53- cells. These results support the hypothesis that apoptosis plays a crucial role in maintaining genomic integrity by selectively eliminating highly mutated cells from the population.

The demonstration site was Retention Basin 281-3H, a shallow catchment basin at the Savannah River Site (SRS), originally built to control contaminated runoff for the H Reactor, and which has been contaminated mainly by radionuclides. The LBNL viscous barrier technology employs barrier liquids which, when injected into the subsurface, produce chemically benign nearly impermeable barriers through a very large increase in viscosity. The initially low-viscosity liquids are emplaced through multiple injection points in the subsurface and the intersecting plumes merge and completely surround the contaminant source and/or plume. Once in place, they gel or cure to form a nearly impermeable barrier. The barrier liquid to be used in this application is Colloidal Silica (CS), an aqueous suspension of silica microspheres in a stabilizing electrolyte. It has excellent durability characteristics, poses no health hazard, is practically unaffected by filtration, and is chemically and biologically benign.

Both the more conductive fractures and the less permeable matrix are generated within the framework of a single-continuum stochastic model based on nonparametric indicator geostatistics. In the stochastic model the fracture zones are distinguished from the matrix by imposing a long-range correlation structure for a small fraction (the highest approximately 11%) of the hydraulic conductivity in the preferred planes of fracture zones. Results of flow arid transport simulation in three dimensions (3D) are used to illustrate the large spatial variability of point measurements, but for spatially integrated quantities the variability is reduced and results become less sensitive to correlation structure. Therefore it is suggested that spatially integrated quantities may be a more appropriate choice for predicting flow and transport in a strongly heterogeneous medium in that they are more commensurate with the level of our ignorance of the site. The issue of spatial variability giving rise to uncertainty in the site characterization of a heterogeneous medium and the prediction of transport results is also addressed. Simulations are carried out for 3D transport from point tracer sources at hundreds of locations in the medium. The breakthrough curve from each point source release is characterized by two parameters: the mean transport velocity and the dispersion coefficient. The results are presented as a statistical distribution of the transport parameters, thus quantifying the uncertainty in predicting flow and transport based on a limited amount of site characterization data.

The authors have developed a new fluid property module for the reservoir simulator TOUGH2 to model grout injection, taking into account the increase of liquid viscosity as a function of time and gel concentration. They have also incorporated into the simulator a model which calculates soil hydraulic properties after solidification of the gel within the pore space. The new fluid property module has been used to design and analyze laboratory experiments and field pilot tests in saturated and unsaturated formations under a variety of subsurface conditions. These applications include modeling barrier emplacement in highly heterogeneous soils in the vadose zone, grout injection into the saturated zone in combination with extraction wells for flow control, the design of verification strategies, and the analysis of barrier performance. In this paper the authors discuss the modeling approach and present simulation results of multiple grout injections into a heterogeneous, unsaturated formation.

Biomass smoke particles, although composed mostly of organic material, are also known to be efficient CCN. However, because smoke particles consist of mixtures of organic and inorganic species, it has not been established whether the organic component is intrinsically CCN active or is intrinsically inactive and rendered CCN active only through association with water-soluble inorganic species. Here we report results of laboratory experiments on smoke particles produced by combustion of eucalyptus, redwood, and cellulose which show that their water-soluble organic fraction is principally derived from smoldering combustion of the cellulosic fuel content. Because cellulose smoke particles are entirely organic, water soluble, and CCN active (at 0.5% and 0.3% supersaturation), we conclude that the water-soluble organic species in smoke particles from smoldering biomass combustion are responsible for their intrinsic CCN activity.

Fractures can provide preferential flow paths for infiltrating liquids that dramatically accelerate contaminant transport compared to predictions based upon spatially uniform infiltration. The actual liquid distribution during infiltration determines the contact area between the flowing water and rock, and liquid residence time, which in turn affects the potential for rock-water and rock-solute interaction, as well as mass transfer between liquid and gas phases. This report summarizes flow- visualization experiments of water percolation through transparent replicas of a natural rock fracture. We have focused on phenomenological and exploratory experiments that can lead to a conceptual model which incorporates the important physical mechanisms that control flow.

The model couples one-dimensional advection and dispersion with water-rock interaction and radioactive decay. We use a Fickian formulation to model longitudinal macrodispersion and present a formula for the groundwater velocity error introduced when dispersion is ignored, as a function of dispersivity and decrease in percent modern carbon. For example, if the longitudinal dispersivity were one tenth the length of observation and percent modern carbon decreased tenfold along a flow path, the error would be 23%. We also present a method for inversion of (super 87) Sr/ (super 86) Sr and (super 14) C data to obtain carbonate dissolution rates and dissolution-corrected water velocities and apply this technique using published data from the Lincolnshire aquifer, England. The results are similar to those obtained using the delta (super 13) C method. Copyright 1996 by the American Geophysical Union.

Studies of the microscale mechanics involved in preferential flow in general, and unsaturated fast flow paths in particular, require the development of new experimental techniques. A new method for constructing glass micromodels has been developed which permits direct visualization and quantification of flow and transport phenomena in fractured porous media. In the fracture-matrix micromodels a sequential etching procedure was developed in order to provide the necessary contrast of depths between matrix pores and fracture apertures. This high contrast in etching depths ensures that very different capillary properties are associated with micromodel "fractures" and "matrix" blocks. Improved techniques were also developed for reducing the pore sizes of the matrix to a natural fine-grained sandstone pore scale. The improved micromodel pattern designs allow for previously unachievable control of boundary conditions. Various saturated and unsaturated fracture flow and transport processes can be visually and quantitatively studied with these micromodels. A method for directly measuring pore-scale flow velocity distribution through tracing trajectories of suspended fluorescent microspheres was also developed. Examples of applications include measurements of velocity profiles in fractures, imbibition, fracture-matrix transient flow, and matrix diffusion. In general, the improved micromodel method provides a unique tool for exploring some of the previously unrecognized flow and transport processes in fractured porous media. This research is directed at providing microscale explanations to some currently unresolved flow and transport issues important in predicting the larger-scale flow processes.

AN - 78104795; 8693163 AB - Industrial societies have altered the earth's environment in ways that could have important, longterm ecological, economic, and health implications. In this paper, we examine the extent to which uncertainty about global climate change could impact the precision of predictions of secondary outcomes such as health impacts of pollution. Using a model that links global climate change with predictions of chemical exposure and human health risk in the Western region of the United States of America (U.S.), we define parameter variabilities and uncertainties and we characterize the resulting outcome variance. As a case study, we consider the public health consequences from releases of hexachlorobenzene (HCB), a ubiquitous multimedia pollutant. By constructing a matrix that links global environmental change both directly and indirectly to potential human-health effects attributable to HCB released into air, soil, and water, we define critical parameter variances in the health risk estimation process. We employ a combined uncertainty/sensitivity analysis to investigate how HCB releases are affected by increasing atmospheric temperature and the accompanying climate alterations that are anticipated. We examine how such uncertainty impacts both the expected magnitude and calculational precision of potential human exposures and health effects. This assessment reveals that uncertain temperature increases of up to 5 degrees C have little impact on either the magnitude or precision of the public-health consequences estimated under existing climate variations for HCB released into air and water in the Western region of the U.S. JF - Risk analysis : an official publication of the Society for Risk Analysis AU - McKone, T E AU - Daniels, J I AU - Goldman, M AD - University of California, Lawrence Berkeley National Laboratory, Berkeley, USA.

The wavelet transforms allow a drastically different approach in the discretization of space. In contrast to the traditional trigonometric basis functions, wavelets approximate a function not by cancellation but by placement of wavelets at appropriate locations. When an abrupt change, such as a shock wave or a spike, occurs in a function, only local coefficients in a wavelet approximation will be affected. The unique feature of wavelets is their Multi-Resolution Analysis (MRA) property, which allows seamless investigation at any spatial resolution. The use of wavelets is tested in the solution of the one-dimensional Buckley-Leverett problem against analytical solutions and solutions obtained from standard numerical models. Two classes of wavelet bases (Daubechies and Chui-Wang) and two methods (Galerkin and collocation) are investigated. We determine that the Chui-Wang wavelets and a collocation method provide the optimum wavelet solution for this type of problem. Increasing the resolution level improves the accuracy of the solution, but the order of the basis function seems to be less important. Our results indicate that wavelet transforms are an effective and accurate method which does not suffer from oscillations or numerical smearing in the presence of steep fronts.

Carbon emissions from the energy sector dominate total greenhouse gas emissions from China and India, and are becoming more significant in Brazil. We compare least-cost scenarios of carbon emissions from the energy sector for each country. Each scenario was developed using the same linear programming approach. In addition to the costs of providing energy services, we analyze the foreign exchange and capital investment required for alternative scenarios. The results indicate that energy efficiency improvements offer a cost-effective option for restraining emissions in each country. Because of Brazil's abundant natural resources, hydropower and biomass significantly add to the potential for restraining future CO sub(2) emissions from electricity generation and transportation. Compared to the Current Trends scenario, imported natural gas can reduce emissions by 25% in China in 2020 and 32% in India in 2025. For India, importing natural gas is less costly than using domestic coal. Overcoming investment and foreign exchange constraints will hold the key to future emissions reductions; these appear manageable for China and Brazil, but not for India.

Selenium was introduced by ponding 3.0 mM solutions of Se(VI) over previously uncontaminated soils. Analyses of soil waters and ponded waters with conventional laboratory methods [hydride-generation atomic absorption spectrometry (HGAAS) and redox electrodes] and with x-ray absorption spectroscopy (XAS) measurements on sediment and water samples provided direct Se speciation of the dominant valence states. The XAS demonstrated that Se in a contaminated sediment from Kesterson Reservoir occurs primarily as the red, monoclinic elemental form. Selenium(VI) reduction to Se(IV) and removal of both species from the aqueous phases (ponded and pore waters) was observed with HGAAS. Reduction of Se(VI) to Se(0) in the sediments was confirmed with XAS. The XAS on all shallow sediments at the end of the ponding period (48 to 51 d) demonstrated that 99 plus or minus 5% of the Se occurred as Se(0). Rapid reoxidation of Se(0) was observed in some of the previously ponded sediments. About 60% of the Se inventory was reoxidized to a mixture of Se(IV) and Se(VI) in unamended sediments within 2 d after sampling. Selenium in sediments that were amended with organic matter remained in the Se(0) state during this short period.

Oxidized forms are generally more biologically available. Surface and subsurface soils from Se-contaminated Kesterson Reservoir were incubated for 2.5 yr at temperatures of 15, 25, and 35 degree C in order to measure Se oxidation rates and help identify the most readily oxidizable fractions. A range of moisture contents was maintained. Six Se fractions: soluble Se(IV), soluble Se(VI), adsorbed Se, organic Se, carbonate Se, and refractory Se, were monitored via periodic extraction. Oxidation rates were estimated based on changes in the relative proportions of these fractions with time. No significant changes were noted in soils from a depth of 0.45 to 0.55 m. Transformations were observed in surface soils (0-0.10 m). The most prominent change was the oxidation of up to 50% of refractory Se to soluble Se(VI). A smaller portion of the organic Se pool was also oxidized. X-ray absorption spectroscopy indicated the dominance of Se(0) in the refractory pool. First-order oxidation rates were between 0.058 and 0.29 yr super(-1) for organic Se, and between 0.11 and 2.4 yr super(-1) for refractory Se, with a strong positive correlation with temperature. No losses of total Se were observed, indicating the relative insignificance of methylation. An apparent plateau in oxidation of the refractory pool suggests heterogeneity of this pool, with some components more readily oxidized than others. With time, currently reduced Se will be oxidized, although some fractions are likely to remain biologically unavailable for decades.

Flow was found to proceed in dendritic patterns along preferential paths, giving rise to such features as localized ponding and bypassing. Limited parameter variation studies have shown strong dependence of seepage patterns on fracture permeability and applied flow rate. The temporal evolution of seeps proceeds on a vast range of time scales. This casts doubt on the applicability of steady-state concepts for water migration in thick unsaturated zones of fractured rock where infiltration is episodic. An approximate invariance of seepage behavior was derived for simultaneous space-and-time scaling. Numerical simulation experiments have confirmed this invariance, as well as its limits of applicability.

Experiments were conducted using two experimental basements to examine the influence of a subslab gravel layer on advective radon entry driven by steady indoor-outdoor pressure differences. The measurements indicate that a high permeability subslab gravel layer increases the advective radon entry rate into the structure by as much as a factor of 30. A three-dimensional, finite-difference model correctly predicts the effect of a subslab gravel layer and open area configuration on advective radon entry driven by steady indoor-outdoor pressure differences; however, the model underpredicts the absolute entry rate into each structure by a factor of 1.5.

Part 1 of the series presents a simplified analytical solution for cases in which a constant-concentration source is located at the top (or the bottom) of the aquifer. The following transport mechanisms have been considered: advection (in the horizontal direction), transverse dispersion (in the vertical direction), adsorption, and biodegradation. In the simplified solution, however, longitudinal dispersion is assumed to be relatively insignificant with respect to advection, and has been neglected. Example calculations are given to show the movement of the contamination front, the development of concentration profiles, the mass transfer rate, and an application to determine the vertical dispersivity. The analytical solution developed in this study can be a useful tool in designing an appropriate monitoring system and an effective groundwater remediation method.

This dissertation examines an important component of the indoor radon problem: the impacts of wind on soil-gas and radon transport and entry into buildings. The research includes experimental and modeling studies of wind's interactions with a building's superstructure and the resulting soil-gas and radon flows in the surrounding soil. In addition to exploring the effects of steady winds, a novel modeling technique is developed to examine the impacts of fluctuating winds on soil-gas and radon transport.

It is designed to operate in environments that are too conductive for ground penetrating radar (GPR) to be effective, and too shallow for standard electromagnetic systems. The VETEM system is a faster profiling complement to the frequency-domain high frequency sounder (HFS). First field tests of the VETEM were made at the Geophysics Performance Evaluation Range at Rabbit Valley west of Grand Junction, Colorado in June and July, 1995. A number of well defined targets of various types are buried there (Allen, 1995). The VETEM system was next used as part of the Electromagnetics Integrated Demonstration (EMID) at the Cold Test Pit at the Idaho National Engineering Laboratory (INEL) in November, 1995. The Cold Test Pit has a number of subareas with buried objects of various types. For the EMID tests, VETEM was run over three gridded areas: the Primary Grid (PG), the Large Object Pit (LOP), and the Calibration Cell (CC). In this paper we display recorded lines from the LOP that show VETEM is responding to electrical properties of the near surface and to buried objects.

Hence, in many cases, there is a gap in our detection capability between the lower limit of GPR and the upper limit of traditional electromagnetics (EM). Bridging this gap is essential to the characterization of buried waste, contaminant plumes, and other environmental and hydrogeological targets located in the shallow subsurface. The Very Early Time Electromagnetic (VETEM) System is designed to ascertain the conductivity and dielectric properties of the shallow subsurface in conductive terrain (Pellerin et al.; 1994, 1995). Hence, the one-dimensional (1-D) and three-dimensional (3-D) numerical modeling algorithms, developed in the first year of the project, contain the full solution to the EM problem including both displacement and conduction currents. The VETEM system fills a gap between EM and GPR, but all three methods are necessary to successfully image the shallow subsurface. The VETEM participants recognize that other electromagnetic instruments and techniques developed in industry, academia and other research institutions for near-surface investigations have been developed since the baseline study was established for the VETEM project (Mac Lean; 1992, 1993). Many of these new instruments lack the interpretational software necessary for high-resolution 3-D imaging of the subsurface, but directly complement the VETEM instrumentation and can benefit greatly from application of the software developed in the VETEM project. Therefore, to achieve the goal of fully 3-D subsurface imaging, the VETEM project is hosting the Electromagnetic Integrated Demonstration (EMID) at the Idaho National Engineering Laboratory's Cold Test Pit (INEL's CTP). Over a dozen EM systems will acquire data over the same survey area for interpretation in conjunction with the VETEM team. To interpret the EMID data, the VETEM participants have been developing forward modeling software, instrumentation, and interpretational software. In addition to interpretation of field data, the forward modeling algorithms are being used in physical analysis of the problem and in the systems analysis devoted to instrument design. The prototype time-domain instrument employs a magnetic dipole transmitter and receiver and operates from 10 nano-second to a micro-second. The USGS high frequency sounder (HFS), which served as the VETEM proof-of-concept, uses the same antenna geometry as the time-domain instrument and acquires data from 30 kHz to 30 MHz. The first VETEM survey was recently conducted at the INEL's CTP as a part of the EMID. The electromagnetic migration technique is being investigated for interpretation the VETEM data. Multi-dimensional inversion and pattern recognition techniques are also available and will be used on complementary datasets acquired in the EMID.

Role of monomer versus dimer. AN - 77993377; 8626380 AB - The role of apolipoprotein A-II (apoA-II) in high density lipoprotein (HDL) structure and metabolism has been studied previously in transgenic mice overexpressing either human or murine apoA-II. These studies have shown differences between these two groups of transgenic animals in the levels of very low density, low density, and high density lipoproteins, in the HDL particle size distribution, and in the relationship between apoA-II levels and lipoprotein levels. To determine whether these differences are due to the fact that human apoA-II is dimeric and murine apoA-II monomeric, we have examined the effects of monomeric human apoA-II (hA-IImon) in transgenic mice. Site-directed mutagenesis (Cys6 -> Ser) was used to generate 15 transgenic founder lines of hA-IImon mice, that contained plasma hA-IImon concentrations over a 10-fold range (11 mg/dl to 185 mg/dl). The hA-IImon floated in the d < or = 1.21 g/ml fraction and migrated as an apoA-II monomer by nonreducing SDS-polyacrylamide gel electrophoresis. HDL levels were not correlated with hA-IImon levels (r = -0.26); HDL particle size and size distribution, as well as very low density and low density lipoprotein levels and sizes, were unchanged compared to nontransgenic control mice. These results suggest that differences between mice overexpressing human dimeric apoA-II and those overexpressing murine apoA-II are the result of sequence differences between these two apoA-II molecules and are not solely due to the fact that human apoA-II exists as a dimer.

A new dual-probe dynamic pressure technique was developed to measure permeability in situ over different length scales and different spatial orientations in the soil. Soils at three sites were studied using the new technique. Each soil was found to have higher horizontal than vertical permeability. Significant scale dependence of permeability was also observed at each site. Permeability increased by a factor of 20 as sampling scale increased from 0.1 to 2 m in a sand soil vegetated with dry grass, and by a factor of 15 as sampling scale increased from 0.1 to 3.5 m in a sandy loam with mature Coast Live Oak trees (Quercus agrifolia). The results indicate that standard methods of permeability assessment can grossly underestimate advective transport of gas phase contaminants through soils.

AN - 78609059; 8807836 AB - BACKGROUNDSensitive and selective molecular recognition is important throughout biology. Certain organisms and toxins use specific binding at the cell surface as a first step towards invasion. A new series of biomolecular materials, with novel optical and interfacial properties, have been designed to sense molecular recognition events. These polymers, the diacetylenic lipids, have previously been shown to undergo chromatic transitions in response to virus binding to the surface of the material.RESULTSGangliosides that specifically bind cholera toxin, heat-labile Escherichia coli enterotoxin and botulinum neurotoxin were incorporated into a matrix of diacetylenic lipids, 5-10% of which were derivatized with sialic acid. The lipids were self-assembled into Langmuir-Blodgett layers and polymerized with ultraviolet irradiation, yielding a polydiacetylene membrane with a characteristic blue color into which the ganglioside is non-covalently incorporated. When toxin is added, the polymerized membrane turns red. The response is specific and selective, and can be quantified by visible absorption spectrophotometry.CONCLUSIONSPolydiacetylenic lipid membranes offer a general 'litmus test' for molecular recognition at the surface of a membrane. A concentration of 20 ppm of protein could be detected using polymerized thin films. The speed, sensitivity and simplicity of the design offers a new and general approach towards the direct colorimetric detection of a variety of different molecules.

II. Experimental detection. AN - 78001537; 8606930 AB - The basic 30-nm chromatin fiber in the mammalian cell consists of an unknown (possibly helical) arrangement of nucleosomes, with about 1.2 kb of DNA per 10-nm length of fiber. Track-structure considerations suggest that interactions of single delta rays or high-LET particles with the chromatin fiber might result in the formation of multiple lesions spread over a few kilobases of DNA (see the accompanying paper: W.R. Holley and A. Chatterjee, Radiat. Res. 145, 188-199, 1996). In particular, multiple DNA double-strand breaks and single-strand breaks may form. To test this experimentally, primary human fibroblasts were labeled with [3H]thymidine and exposed at 0 degrees C to X rays or accelerated nitrogen or iron ions in the LET range of 97-440 keV/microns. DNA was isolated inside agarose plugs and subjected to agarose gel electrophoresis under conditions that allowed good separation of 0.1-2 kb size DNA. The bulk of DNA remained in the well or migrated only a small distance into the gel. It was found that DNA fragments in the expected size range were formed linearly with dose with an efficiency that increased with LET. A comparison of the yield of such fragments with the yield of total DNA double-strand breaks suggests that for the high-LET ions a substantial proportion (20-90%) of DNA double-strand breaks are accompanied within 0.1-2 kb by at least one additional DNA double-strand break. It is shown that these results are in good agreement with theoretical calculations based on treating the 30-nm chromatin fiber as the target for ionizing particles. Theoretical considerations also predict that the clusters will contain numerous single-strand breaks and base damages. It is proposed that such clusters be designated "regionally multiply damaged sites." Postirradiation incubation at 37 degrees C resulted in a decline in the number of short DNA fragments, suggesting a repair activity. The biological significance of regionally multiply damaged sites is presently unknown.

The relationship is demonstrated between salinity gradients in the Bay and stable isotopic compositions, which show that these compositional variations are recorded in the carbonate shells of molluscs living in the estuary. The use of stable isotope compositions of growth bands in fossil mollusc shells for determining seasonal freshwater inflow and salinity variations in the Bay is evaluated. The Delta (super 18) O and Delta D values and estuarine salinity indicate a linear mixing relationship between sea-water from the Pacific and fresh water from the Sacramento-San Joaquin river system.

AN - 78720604; 9164652 AB - The extracellular matrix (ECM) is a dominant regulator of tissue development and homeostasis. "Designer microenvironments" in culture and in vivo model systems have shown that the ECM regulates growth, differentiation, and apoptosis in murine and human mammary epithelial cells (MEC) through a hierarchy of transcriptional events involving the intricate interplay between soluble and physical signaling pathways. Furthermore, these studies have shown that these pathways direct and in turn are influenced by the tissue structure. Tissue structure is directed by the cooperative interactions of the cell-cell and cell-ECM pathways and can be modified by stromal factors. Not surprisingly then, loss of tissue structure and alterations in ECM components are associated with the appearance and dissemination of breast tumors, and malignancy is associated with perturbations in cell adhesion, changes in adhesion molecules, and a stromal reaction. Several lines of evidence now support the contention that the pathogenesis of breast cancer is determined (at least in part) by the dynamic interplay between the ductal epithelial cells, the microenvironment, and the tissue structure (acini). Thus, to understand the mechanisms involved in carcinogenesis, the role of the microenvironment (ECM as well as the stromal cells) with respect to tissue structure should be considered and studied. Towards this goal, we have established a unique human MEC model of tumorigenesis, which in concert with a three-dimensional assay, recapitulates many of the genetic and morphological changes observed in breast in cancer in vivo. We are currently using this system to understand the role of the microenvironment and tissue structure in breast cancer progression.

AN - 77977878; 8565126 AB - We previously reported our finding that human cells contain glycosylase activity toward all four etheno bases formed in DNA by chloroacetaldehyde and related bi-functional aldehydes. By enzyme purification, including FPLC, we isolated two separate glycosylase activities for 1,N6-ethenoadenine (epsilon A) and for 3,N4-ethenocytosine (epsilon C) respectively, from crude HeLa cell-free extracts, which also contained a number of well-described glycosylases. When Mono-S FPLC purified proteins were assayed against defined oligomers containing either epsilon A or epsilon C, it was found that epsilon A and epsilon C glycosylases were completely separated. It could also be demonstrated that each enzyme bound to and cut only epsilon A- or epsilon C-containing oligomers respectively. There was no overlap in specificity for these two substrates. Several other human glycosylase substrates were also tested and none were cleaved by epsilon C glycosylase. The epsilon C glycosylase activity identified in the present study apparently represents a previously unknown glycosylase. This work also suggests that enzyme recognition of closely related DNA adducts may depend upon subtle changes in local conformation.

Preliminary data has been collected from two sites. One site was the location of a former refinery operated between 1879 and 1903. Contamination levels are spotty, with methane levels of greater than 60% measured in soil gas from one point. At this location, the radiocarbon contents of all the samples are low (<0.3 times modern). The stable carbon isotope ratio of DIC is high (+18 per mil), but carbon dioxide from overlying soil gas is very low (-31.7 per mil at 122 cm and -34.3 per mil at 61 cm). At the other site, approximately 1.4 million liters of AVGAS leaked out of underground fuel storage tanks during the 1960s and early 1970s. The area above the former storage tanks is currently covered with grass, but the contaminant plume extends about 0.8 km underneath an adjacent parking lot. Underneath the parking lot, oxygen levels are less than 2.5% by volume, carbon dioxide is greater than 12%, and methane reaches 25%. Radiocarbon levels in the carbon dioxide and methane are all less than 0.1 times modern indicating that most of the carbon was derived from hydrocarbons. Stable carbon isotope ratios of the carbon dioxide vary significantly, consistent with varying levels of carbon dioxide produced from oxidation of methane. At both sites, in areas of significant contamination, methanogenesis at depth gives way to methane oxidation in shallower samples.

Examination of core and shaft exposures has revealed that there are multiple scales of porosity within the Culebra including: fractures ranging from microscale to large, vuggy zones, and inter-granular porosity. A series of hydraulic and tracer tests has been conducted to evaluate the flow and transport properties of the Culebra. A primary objective of single-well injection-withdrawal and multiwell convergent-flow tracer tests was to evaluate whether there is significant solute diffusion from fractures into the rock matrix. To interpret tracer test results, numerical simulations have been conducted using single- and double-porosity models with homogeneous and heterogeneous hydraulic conductivity fields. Simulations to date indicate that it is not possible to model the single-well data without significant matrix diffusion. These simulations further suggest that both the single- and multiwell data cannot be adequately explained using a classical double-porosity model and heterogeneous permeability fields. However, an excellent fit to the single-well data can be obtained using a model that incorporates a statistical distribution of mass transfer rates (multirate diffusion). This distribution of effective diffusion rates represents variations in fracture spacing (surface area for diffusion and block size) and tortuosity of pores which is consistant with the observed scales of porosity.

We developed a technology to study flow in fractured rocks based on vertical and slanted boreholes equipped with tensiometers, piezometers, thermistors, Time Domain Reflectometry, and electrical resistivity measurements. Based on a scheme of functional components of a basalt flow, we hypothesize that flow in fractured basalt of the vadose zone is primarily affected by: (a) the pattern of interconnected column-bounding (vertical and subvertical) and column-normal (horizontal and subhorizontal) fractures, vesicular layers, and rubble zones, and (b) boundary conditions for water/air flow. For the upper basalt flow, the fracture system has been described on three scales: microscale--smallest discontinuities that act as fluid conductors, mesoscale--a set of merging basalt columns, and macroscale--an individual basalt flow surrounded by rubble zones. Column-bounding fractures, which are primary pathways for fast vertical infiltration, are terminated within the basalt flow and linked to column-normal fractures. It is assumed that when hydraulic pressure in a vertical fracture increases above the critical value, water may penetrate into horizontal fractures, and then a hydraulic connection between column-bounding fractures is established. The central fractured zone and rubble zones are primary pathways for lateral water migration on the macroscale. The near-surface soil-infilled fractures are a controlling factor for ponded infiltration from the land surface. Results of numerical modeling have predicted that preferential flow, which originates along column-bounding fractures, affects the creation of perched water zones within the central fractured zone and rubble zones. This hypothesis will be tested in the infiltration tests planned for July-August 1996.

A thorough understanding of non-Newtonian fluid flow through porous media is of fundamental importance in these engineering applications. Considerable progress has been made in our understanding of single-phase porous flow behavior of non-Newtonian fluids through many quantitative and experimental studies in the past few decades. However, very little research can be found in the literature regarding multi-phase non-Newtonian fluid flow or numerical modeling approaches for such analyses. For non-Newtonian fluid flow through porous media, the governing equations become non-linear, even under single-phase flow conditions, because effective viscosity for the non-Newtonian fluid is a highly non-linear function of the shear rate, or the pore velocity. The solution of such problems can in general only be obtained by numerical methods. We have developed a three-dimensional, fully implicit, integral finite difference simulator for single- and multi-phase flow of non-Newtonian fluids in porous/fractured media. The methodology, architecture and numerical scheme of the model are based on a general multi-phase, multi-component fluid and heat flow simulator, the TOUGH2 code (Pruess, 1991). Several rheological models for Power-law and Bingham non-Newtonian fluids have been incorporated into the model. In addition, the model predictions on single- and multi-phase flow of Power-law and Bingham fluids have been verified against the analytical solutions available for these problems, and in all the cases, the numerical simulations are in good agreement with the analytical solutions. In this presentation, we will discuss the numerical scheme used in the treatment of non-Newtonian properties, and several benchmark problems for model verification.

However, most of these models do not account for fluid or solute exchange between the fractures and the porous matrix, although diffusion into the matrix pores can have a major impact on the spreading of contaminants. In the present paper a new finite element code TRIPOLY is introduced which combines a powerful fracture network simulator with an efficient method to account for the diffusive interaction between the fractures and the adjacent matrix blocks. The fracture network simulator used in TRIPOLY features a mixed Lagrangian-Eulerian solution scheme for the transport in fractures, combined with an adaptive gridding technique to account for sharp concentration fronts. Lagrangian-Eulerian schemes have been introduced in recent years to avoid numerical problems in the solution of the advection-dispersion equation. They are especially effective in advection dominated transport, which may often occur in fractures. Thus TRIPOLY is capable of handling very heterogeneous fracture networks without the need for very fine spatial or temporal discretizations. The fracture-matrix interaction is calculated with an efficient method which has been successfully used in the past for dual-porosity models. Discrete fractures and matrix blocks are treated as two different systems, and the interaction is modeled by introducing sink/source terms in both systems. It is assumed that diffusive transport in the matrix can be approximated as a one-dimensional process, perpendicular to the adjacent fracture surfaces. A direct solution scheme is employed to solve the coupled fracture and matrix equations. The newly developed combination of the fracture network simulator and the fracture-matrix interaction module allows for detailed studies of spreading processes in fractured porous rock. We present a sample application which demonstrate the codes ability of handling large-scale fracture-matrix systems comprising individual fractures and matrix blocks of arbitrary size and shape.

Flow occurs mainly in a few tortuous channels, and solutes traveling along those channels may be transported many times faster than in homogeneous media. This may be very important in problems concerning the transport of toxic wastes. In saturated media flow channels develop along areas of large permeability. In unsaturated soil, however, large permeabilities are correlated to large pore volumes, which drain faster than the smaller pores. This can lead to strongly reduced flow rates along zones of high permeabilities. Thus, the degree of channeling and the location of channels might be very different from the saturated case. To study such behavior, we performed numerical simulations of fluid flow and solute transport in a two-dimensional vertical cross-section of a strongly heterogeneous porous medium. Three realizations of heterogeneous fields were generated in our study using geostatistical methods. Different saturation scenarios were applied varying from fully saturated to highly unsaturated conditions, corresponding to different infiltration rates into the soil. It was found that the degree of channeling, the location of channels and the hydraulic properties along channels are very much dependent on the overall saturation. Strong channeling effects were obtained in both fully saturated and in low saturation cases. However, with fully saturated conditions channels develop along zones of high absolute permeabilities; in the case of low saturation we find channels only in zones of low absolute permeabilities. Within intermediate saturation ranges, channeling effects are less significant and the system exhibits a more homogeneous flow pattern. Here, the strong heterogeneities in the flow field are dampened, and the standard deviation of the effective permeabilities (product of absolute and relative permeabilities) drops significantly compared to the standard deviation of the absolute permeabilities. The dispersion of solutes traveling in such systems corresponds directly to the degree of channeling; in cases when flow channeling is less evident we observe much smaller dispersivities than in cases with strong channeling. The specific location and geometry of the channels can be very different from realization to realization. However, we found that the hydraulic properties of the channels were independent of the particular realization, provided that the same saturation scenario was considered. Thus, flow and transport in the entire porous medium can be characterized in terms of the specific distribution of the channel properties associated with a certain saturation scenario.

Two inverse approaches for constructing fracture flow models were applied to the interference test data. The first approach creates equivalent discontinuum models that conceptualize the fracture system as a partially filled lattice of (constant aperture) conductors which are locally connected or disconnected to reproduce the observed fluid flow behavior. The second approach creates variable aperture lattice models that represent the fracture system as a fully connected network composed of conductors of varying apertures. Both approaches successfully reproduced the transient pressure behavior at the pumping and observation wells and indicated a preferential fracture flow path between two wells aligned in an east-northeast direction, the dominant direction of fracturing mapped in the area. Crosswell and single well seismic experiments were performed before and after air injection designed to displace water from the fracture flow path and increase seismic visibility. The crosswell experiments showed that replacement of water with a gas (in this case air) produces significant changes in the seismic signal. The single well reflection surveys were able to precisely locate the position of the fracture flow path indicated by inverse modelling of the interference tests. To validate the results of the field experiments, we drilled and cored a slant well that intersected the fracture flow path at the target depth.

In mammals, apoB can be edited post-transcriptionally to encode a truncated form of apoB (apoB48) that is unable to form either of these atherogenic lipoproteins. To study the effect of increasing hepatic apoB editing activity on formation of Lp(a), a recombinant adenovirus encoding rat apoBEC-1, the cytidine deaminase component of the apoB mRNA editing complex, was administered to human apoB/apo(a) transgenic mice. This resulted in expression of apoBEC-1 in hepatocytes of these mice, increased hepatic editing of human apoB mRNA, and decreased plasma levels of human apoB100 and Lp(a). The apoBEC-1 recombinant adenovirus was also administered to rabbits, an animal which, like humans, naturally lacks hepatic apoB editing. Expression of the exogenous apoBEC-1 in rabbit liver resulted in editing of up to 10% of apoB mRNA. Hepatic apoB editing was associated with lower LDL levels in these rabbits relative to those treated with a control adenovirus. However, LDL levels were elevated significantly in both animals as a result of adenovirus injection. These studies demonstrate that introduction of the cytidine deaminase apoBEC-1 is sufficient to induce hepatic apoB editing in an animal lacking this activity, and that induction of editing could serve as a novel approach for lowering plasma concentrations of the atherogenic lipoproteins Lp(a) and LDL.

The sparser the data, the larger the subareas must be in order to calculate stable rates. This dilemma is avoided with the technique of density equalizing map projections (DEMP). Boundaries of geographic subregions are adjusted to equalize population density over the entire study area. Case locations plotted on the transformed map should have a uniform distribution if the underlying disease rates are constant. The present report describes the application of the DEMP technique to 401 childhood cancer cases occurring between 1980 and 1988 in four California counties, with the use of map files and population data for the 262 tracts of the 1980 Census. A kth nearest neighbour analysis provides strong evidence for geographic non-uniformity in tract rates (p < 10 super(-4)). No such effect is observed for artificial cases generated under the assumption of constant rates. Work is in progress to repeat the analysis with improved population estimates derived from both 1980 and 1990 Census data. Final epidemiologic conclusions will be reported when that analysis is complete.

A numerical model was used to analyse the coupled problem of fluid flow and rock/fracture deformation during the field tests. Fracture closure and virgin normal stress was determined from the zero-flow pressure in a well pressure-well flow diagram. The cyclic hydraulic jacking tests gave a zero-flow pressure in close agreement with both the shut-in pressure and the weight of the overburden rock for four out of six tested joints. For the two remaining joints the virgin normal stress could be estimated by a linear extrapolation to zero-flow rate. The zero-flow pressure is clearly defined and is insensitive to the transmissivity and non-linear normal stiffness of the fracture near the wellbore. Cyclic hydraulic jacking is therefore an alternative to traditional shut-in analysis when shut-in pressure is difficult to determine.

The regressor variables are the lateral and vertical force components measured at the toe and heel bindings. The Mb and Mk regression model coefficients, standard deviations, and correlation coefficients are dependent on the distance from the center of ankle flexion to the boot top and to the knee. The regression models are applied to skiing runs during which slalom turning, forward/backward leaning, falling, and jumping maneuvers are executed by the subjects.

For example, both the saturated zone and the unsaturated zone at Yucca Mountain, Nevada, contain many hydrogeologic units that are extensively fractured. When modeling the hydrological behavior of these sites, for either the purpose of site characterization or performance assessment, computational gridblocks are often used that contain large numbers of fractures. In order to treat these gridblocks as equivalent continua, it is necessary to develop a procedure for relating the hydraulic properties of the individual fractures, and the topology of the fracture network, to the overall gridblock-scale permeability. One aspect of this problem is that of determining the in situ hydraulic properties of the individual fractures. Another aspect is to reconstruct the three-dimensional geometry of the fracture network based on borehole or outcrop measurements. The final stage in the problem is that of taking a network of known geometry (which may be stochastically generated), and determining its effective gridblock-scale conductivity. The purpose of this paper is to describe a simple procedure for solving this latter problem, and to demonstrate its use in cases of both saturated and unsaturated flow.

AN - 77781513; 8618842 AB - An assay that allows measurement of absolute induction frequencies for DNA double-strand breaks (dsbs) in defined regions of the genome and that quantitates rejoining of correct DNA ends has been used to study repair of dsbs in normal human fibroblasts after x-irradiation. The approach involves hybridization of single-copy DNA probes to Not I restriction fragments separated according to size by pulsed-field gel electrophoresis. Induction of dsbs is quantitated from the decrease in the intensity of the hybridizing restriction fragment and an accumulation of a smear below the band. Rejoining of dsbs results in reconstitution of the intact restriction fragment only if correct DNA ends are joined. By comparing results from this technique with results from a conventional electrophoresis assay that detects all rejoining events, it is possible to quantitate the misrejoining frequency. Three Not I fragments on the long arm of chromosome 21 were investigated with regard to dsb induction, yielding an identical induction rate of 5.8 X 10(-3) break per megabase pair per Gy. Correct dsb rejoining was measured for two of these Not I fragments after initial doses of 80 and 160 Gy. The misrejoining frequency was about 25% for both fragments and was independent of dose. This result appears to be representative for the whole genome as shown by analysis of the entire Not I fragment distribution. The correct rejoining events primarily occurred within the first 2 h, while the misrejoining kinetics included a much slower component, with about half of the events occurring between 2 and 24 h.

The primary objectives of developing the 3-D site-scale model are to predict the ambient hydrogeological conditions and the movement of moisture and gas within the unsaturated zone of the mountain. In addition, the model has the capability of modeling non-isothermal flow and transport phenomena at the mountain. Emplacement of heat-generating, high-level nuclear wastes at Yucca Mountain would create complex multiphase fluid flow and heat transfer processes. The physical mechanisms include conductive and convective heat transfer, phase change phenomena (vaporization and condensation), flow of liquid and gas phases under variably-saturated condition, diffusion and dispersion of vapor and gas, vapor sorption, and vapor-pressure lowering effects.

AN - 77691426; 7583585 AB - The enhanced oxidizability of smaller, more dense LDL is explained in part by a lower content of antioxidants, including ubiquinol-10 and alpha-tocopherol. In the present studies, we also observed greater rates of depletion of alpha-tocopherol (mole per mole LDL per minute) in dense (d = 1,040 to 1,054 g/mL) compared with buoyant (d = 1,026 to 1,032 g/mL) LDL in the presence of either Cu2+ or the radical-generating agent 2-2'-azobis (2-amidinopropane)dihydrochloride. Differences were particularly pronounced at the lowest Cu2+ concentration tested (0.25 mumol/L), with a fivefold greater rate in dense LDL. At higher concentrations (1.0 and 2.5 mumol/L Cu2+), there was a greater dependence of depletion rate on initial amount of alpha-tocopherol, which was reduced in dense LDL, thus resulting in smaller subfraction-dependent differences in depletion rates. Inclusion of ascorbic acid (15 mumol/L), an aqueous antioxidant capable of recycling alpha-tocopherol by hydrogen donation, was found to extend the course of Cu(2+)-induced alpha-tocopherol depletion in both buoyant and dense LDL, but this effect was more pronounced in dense LDL (time to half-maximal alpha-tocopherol depletion was extended 15.6-fold and 21.2-fold in buoyant and dense LDL, respectively, at 2.5 mumol/L Cu2+; P< .05). Thus, dense LDL exhibits more rapid alpha-tocopherol depletion and conjugated diene formation than buoyant LDL when oxidation is performed in the absence of ascorbic acid, but these differences are reversed in the presence of ascorbic acid.(ABSTRACT TRUNCATED AT 250 WORDS) JF - Arteriosclerosis, thrombosis, and vascular biology AU - Tribble, D L AU - Thiel, P M AU - van den Berg, J J AU - Krauss, R M AD - Department of Molecular and Nuclear Medicine, Lawrence Berkeley National Laboratory, Calif, USA.

The welded tuffs have very low permeability, offering protection from flowing groundwater. The repository horizon, although of low permeability, is known to be fractured, suggesting the possibility of fast paths for contaminant transport. As part of the repository evaluation, this study has been undertaken to characterize fractures from Yucca Mountain tuffs. Another purpose of this study is to gain insight into pore-level phenomena occurring during multiphase flow in fractures generally. For this reason measurements were made not only in the actual fractures, but also in transparent replicas that reproduce the fracture void geometry. Use of transparent replicas allows observation of displacement phenomena and estimation of fracture saturation.

Reconnaissance soil-gas surveys found samples from 15 cm depth containing >> 20% CO (sub 2) and trees were dead in areas emitting >> 30% CO (sub 2) . Further soil-gas analyses showed CO (sub 2) emissions up to 96% indicating a total CO (sub 2) flux of > or = 1200 tonnes/day. This forest destruction is a surface manifestation of magmatism in this mountain which shows only weak fumarolic activity and no summit volcanism. The size and duration of the CO (sub 2) flux indicates a large, deep magma source and the tapping of a large reservoir of high-P gas. Analyses are presented of CO (sub 2) , O (sub 2) , N (sub 2) Delta (super 13) C, (super 14) C and (super 3) He/ (super 4) He.

The primary purpose of these operations was to examine the groundwater plume moving from Lake Karachai toward the river. Activities encompassed isolation of hydrologic intervals in two wells and production of water from these intervals, to compare isolated versus open-well sampling methods; surface and soil-water sampling, accompanying radiometric measurements and subsequent chemical analyses; and electrical resistivity profiling in areas of expected contrasting resistivity. Preliminary results indicate that (1) Co-60 and Cs-137 are present in small concentrations in water of the Mishelyak River, (2) analyses of water samples collected by a downhole sampler and of water produced from packed-off intervals agree within limits of laboratory accuracy, attesting to the efficacy of the sampling methods presently used by the Russian workers; and (3) strong contrasts occur between the electrical resistivities of soil and bedrock. Further collaborative work is strongly recommended, and should include more detailed isolation of intervals in wells by multi-packer installations, to better determine the geochemical and hydrological characteristics of the Karachai-Mishelyak system; deployment of a broader soil-water and soil sampling array; a more detailed examination of the distribution and concentration of radionuclides by high-resolution field gamma spectrometry; and a detailing of the area's electrical resistivity setting, using a mobile electromagnetic measurement system.

This realization led to the concept that air injection could be used in the context of remedial strategies to create low permeability barriers to contaminated water and NAPL migration. Air offers a number of significant advantages as a barrier fluid: it is not a contaminant, already exists in the vadose zone, is abundant, easily available, free of charge, and has well-known thermodynamic properties. This report provides a brief summary of air barrier modeling results to date.

Most of this work has dealt with flow and transport in single-phase, isothermal conditions. The present paper is concerned with multiphase and nonisothermal flows in strongly heterogeneous media. A primary driver of our studies is the hydrogeological system at Yucca Mountain, which is currently being evaluated by the Department of Energy for its suitability as the site of the first geologic repository for civilian high-level nuclear wastes in the US Yucca Mountain is located in the and Southwest, near the Nevada-California border. Going from large scale to small, formation heterogeneities at Yucca Mountain include (i) alternating tilting layers of welded and non-welded tuffs with different matrix permeability and variable degree of fracturing, (ii) major fault systems, (iii) well-connected and permeable fracture networks in low-permeability rocks, and (iv) individual fractures with highly variable apertures.

Apo(a) is a large, evolutionary new gene (present primarily in primates) for which considerable controversy exists concerning the factors that regulate its expression. To investigate the in vivo regulation of apo(a), we have created several lines of YAC transgenic mice containing a 110-kb human apo(a) gene surrounded by greater than 60 kb of 5' and 3' flanking DNA. Studies in humans have suggested that acute-phase inducers increase and sex steroids decrease apo(a) concentrations, but these results are controversial. Analysis of the YAC transgenic mice conclusively supports the hypothesized role of sex steroids and refutes the suggested role of acute-phase inducers in regulating the apo(a) gene.

Unlike most previous analyses, we base our analysis on a newly published international data set covering vehicle activity, passenger travel and fuel use by mode. We calculate how changes in activity, modal composition and the energy intensity of each mode contributed to changes in total energy use from travel in nine countries between 1973 and 1992. Increased travel activity and modal shifts boosted energy use, while reduction in modal energy intensities reduced energy use from automobiles in the USA and in air travel throughout the sample of countries. We show how activity, modal shift and modal energy intensities affected CO sub(2) emissions from travel. Noting that the shifts of fuels within transport has been small, even counting shifts in the fuels used to produce the small amount of electricity used for passenger transport in every country, we find that increased activity and modal shifts also raised CO sub(2) emissions from travel in every country except the USA. We discuss briefly how a change in fuel mix, lower transport energy intensities, or even reduced levels of travel might lead to restraining or reducing CO sub(2) emissions from travel.

This is presently done by procedures such as clone fingerprinting, Southern blot analysis or clone end sequencing. We present a complementary analytical technique to map directly cloned DNA sequences on to individual stretched DNA molecules. This approach uses the hydrodynamic force of a receding meniscus to prepare straight high molecular weight DNA molecules that provide a linear template of similar to 2.3 kb/ mu m on to which the cloned probes can be mapped by in situ hybridization. This technique has numerous advantages such as a very high density of mapping templates, reproducible stretching of the mapping template providing a linear genomic scale, determination of clone orientation and direct visualization of DNA repeats. The utility and accuracy of quantitative DNA fiber mapping are illustrated through three examples: (i) mapping of lambda DNA restriction fragments along linearized similar to 49 kb long lambda phage DNA molecules with similar to 1 kb precision; (ii) localization of the overlap between a cosmid and a colinear P1 clone; and (iii) mapping of P1 clones along a similar to 490 kb yeast artificial chromosome (YAC) with similar to 5 kb precision and estimation of the similar to 25 kb gap between them.

The overall root-mean-square deviation for structured regions was 0.75( plus or minus 0.15) angstrom. The three-helix bundle and four-stranded beta -sheet are well defined with rmsd of 0.53( plus or minus 0.10) angstrom and 0.60( plus or minus 0.17) angstrom, respectively Helix H2 is underwound and bent near Pro45. The angle between helix H2 and the proposed recognition helix H3 is 96( plus or minus 6) degree . Detailed comparisons are made with the X-ray structure of this protein as well as other structural studies on HSF. Overall, the results are consistent with the earlier studies. Differences are related to protein-protein interactions in the crystal and dynamics in solution. Backbone dynamics was investigated via super(15)N relaxation. The average R sub(1), R sub(2) and NOE values for residues in segments of secondary structure were 1.9( plus or minus 0.9) s super(-1), 7.8( plus or minus 0.9) s super(-1) and 0.81( plus or minus 0.05), respectively The correlation time based on these data was 5.6( plus or minus 0.4) ns. Motional order parameters were calculated by fitting the relaxation data to one of three models. Low-order parameters were found for residues that comprise the turn between helices H2 and H3 (residues Lys49 to Phe53), and most strikingly the 16 residue wing (residues Va168 to Arg83). These data are consistent with the lack of long-range NOEs identified in these regions. The data provide a basis for comparison with results of the protein-DNA complex. The relationship between structure and function is discussed.

It included process waste assessment, process optimization and treatability analysis of the treatment system, and source reduction assessment. The results of a process waste assessment indicated that over 99.5% of the waste stream was rinsewater and less than 0.5% was characterized as hazardous waste. This finding led to a thorough source reduction assessment. From the process and treatability analysis, it was found that an organic chelating ligand in the wastewater was causing a copper precipitation problem. The results of a series of bench and process experiments indicated that optimization of pH, chemical dosage, and addition of ferrous sulfate were needed to destabilize the complexed copper. The destabilization mechanism of Cu-EDTA with ferrous sulfate at pH 6-9 was discussed. Different separation/recycling technologies were also evaluated through the source reduction assessment. A closed-loop process was simulated and designed. Through the source reduction and treatment process optimization efforts, at least 90% reduction of total acid wastes and wastewater and more than 99% metal removal were achieved. A material lifecycle analysis was also performed. The results indicated that a total quality control strategy is crucial to minimize wastes and reduce product rejection rate.

Using gene targeting in mice, we have deleted a 16 kilobase region encompassing both adult alpha -globin genes. Animals homozygous for this deletion become hydropic and die late in gestation mimicking humans with hydrops fetalis. Introduction of a human alpha -globin transgene rescued these animals from perinatal death thus demonstrating the utility of this murine model in the development of cellular and gene based approaches for treating this human genetic disease.

The IOVPS uses a cyclone inlet for removal of particles greater than 2.5 mu m (D sub(50)) from the airstream, followed by two or three sandblasted glass annular denuders coated with ground particles of an adsorbent resin. The denuders trap the gas-phase species of interest before the airstream passes through a filter and a backup denuder. Extracts of the denuders and filters are analyzed for the semi-volatile species of interest. The IOVPS has been tested and validated for sampling semi-volatile polycyclic aromatic hydrocarbons (PAH) in indoor laboratory room air and environmental tobacco smoke (ETS). Ground XAD-4 was the adsorbent for these initial studies. Gas- and particulate-phase concentrations of semi-volatile PAH are presented for these two environments. The new sampler provides the means for directly determining phase distributions of PAH and other classes of semi-volatile organic species, rather than by difference or by techniques that are subject to large positive and negative artifacts.

With the task ventilation system, occupants can adjust the flow rate and direction of air supplied to their work space through floor-mounted supply grilles. Air exits the ventilated space through a ceiling-mounted return grille. To study indoor airflow patterns, the age of air at multiple indoor locations was measured using the tracer gas step-up procedure. To study the intra-room transport of tobacco smoke particles, cigarettes were smoked mechanically in one workstation and particle concentrations were measured at multiple indoor locations. Our major findings are as follows. (1) Deviations from a uniform age of air, and a uniform particle concentration, were generally less than 30%. (2) With two floor-supply units operating and supply air directed toward the occupant, the age of air in the breathing zone was about 20-40% less than the age of air that would occur in the room if the air was perfectly mixed. (3) With two floor-supply units operating, the air appears to travel from the floor to the ceiling in a piston-like flow pattern. (4) With three floor-supply units operating, a two-zone flow pattern, with a piston-like flow in the lower region of the room and mixing in the upper region, was evident at some operating conditions. (5) A strong correlation was found between the rate of change in the average age of air with height and two factors hypothesized to be determinants of the indoor airflow pattern. (6) Workstations without a cigarette smoking machine and with an operating task ventilation system were not significantly protected from tobacco smoke in an adjacent workstation.

Using super(32)P-postlabeling, we observed relative DNA adduct levels of 0 to 13.7 x 10 super(-7) following continuous exposure to 0 to 496 nM B[a]P for 12 days and relative levels of 0 to 10 x 10 super(-7) after exposure to 248 nM B[a]P over a range of 0 to 16 days. Mean numbers of micronuclei were 1.7, 6.3, and 16.4/1000 red blood cells after exposure to 0, 31, and 248 nM B[a]P, respectively, for 14 days. Micronuclei also ranged from 1.3 to 120.5/1000 red blood cells following exposure to 248 nM B[a]P over a range of 0 to 16 days. Comparatively, levels of both DNA adducts and micronuclei were greatly reduced in animals exposed previously to 31 and 248 nM B[a]P, but assayed at metamorphosis. Larvae exposed to 248 nM B[a]P for 14 days took approximately 4 days longer to metamorphose than unexposed larvae. This increased time to metamorphosis was associated with increased DNA adducts and micronuclei in larvae exposed to 248 nM B[a]P. However, DNA adducts and micronuclei also increased in larvae exposed to 31 nM B[a]P, while time to metamorphosis did not. Larval wet weight was reduced by as much as 44% immediately following exposure to B[a]P. However, there was no effect of exposure on wet weight at metamorphosis. Exposed animals were up to 2 developmental stages younger than unexposed animals in one experiment, but differences among exposed and unexposed animals were less distinct in a second experiment. These studies suggest that DNA adducts and micronuclei can be sensitive measures of sublethal DNA damage, as well as possible short-term indicators of indirect effects on fitness in amphibians.

An outline of the structure of the two computer codes is given, together with the relevant equations. A new module, COUPLE, has been written to serve as an interface between TOUGH and WFSA. Two sample problems are given to illustrate the use of the coupled codes. One of these problems compares the results of the new simulation method to those obtained by using the deliverability option in TOUGH. The coupled computing procedure is shown to simulate more accurately the behavior of a geothermal reservoir under exploitation.

We have conducted chamber experiments to test this combination of techniques using an Open Path Fourier Transform Infrared Spectrometer (OP-FTIR) and a standard algebraic reconstruction technique (ART). ART was found to converge to solutions that showed excellent agreement with the ray integral concentrations measured by the FTIR but were inconsistent with simultaneously gathered point sample concentration measurements. A new CT method was developed based on (a) the superposition of bivariate Gaussians to model the concentration distribution and (b) a simulated annealing minimization routine to find the parameters of the Gaussians that resulted in the best fit to the ray integral concentration data. This new method, named smooth basis function minimization (SBFM) generated reconstructions that agreed well, both qualitatively and quantitatively, with the concentration profiles generated from point sampling. We present one set of illustrative experimental data to compare the performance of ART and SBFM. JF - Proceedings of SPIE - The International Society for Optical Engineering.

Several factors affecting the accuracy of the reconstructed map and the detection limits that can be achieved in the field are discussed. The estimated cost and capabilities of the system are compared with those of a more conventional gas monitoring system that might operate over a similar spatial extent. The paper includes a description of a proposed system that is designed to produce a map of multiple gaseous contaminants with a resolution of 12 m x 12 m in a time of approximately 10 minutes by sequentially measuring the contaminant concentrations along 48 intersecting beam paths and then reconstructing the map using a CT algorithm adapted to detect Gaussian plumes.

This process, termed replicative senescence, is thought to be a tumor-suppressive mechanism and an underlying cause of aging. There is ample evidence that escape from senescence, or immortality, is important for malignant transformation. By contrast, the role of replicative senescence in organismic aging is controversial. Studies on cells cultured from donors of different ages, genetic backgrounds, or species suggest that senescence occurs in vivo and that organismic lifespan and cell replicative lifespan are under common genetic control. However, senescent cells cannot be distinguished from quiescent or terminally differentiated cells in tissues. Thus, evidence that senescent cells exist and accumulate with age in vivo is lacking. We show that several human cells express a beta -galactosidase, histochemically detectable at pH 6, upon senescence in culture. This marker was expressed by senescent, but not presenescent, fibroblasts and keratinocytes but was absent from quiescent fibroblasts and terminally differentiated keratinocytes. It was also absent from immortal cells but was induced by genetic manipulations that reversed immortality. In skin samples from human donors of different age, there was an age-dependent increase in this marker in dermal fibroblasts and epidermal keratinocytes. This marker provides in situ evidence that senescent cells may exist and accumulate with age in vivo.

This represents a fundamental step in the application of high-frequency seismic measurements to detect and delineate NAPL contamination in groundwater. The NAPL's used are n-dodecane, iso-octane and Freon 113 registered . P-wave velocity changes almost linearly as a function of the fraction of pore space occupied by NAPL. At a given NAPL fraction, the velocities rank with the bulk moduli of the NAPL's. The percent change in velocity at residual water saturation relative to the water-saturated medium ranges from 15% for n-dodecane to 31% for Freon 113 registered . Velocity changes are significant relative to the ability of seismic methods to detect changes on the order of 5%. These data are described by a model previously derived by G.T. Kuster and M.N. Toksoez of P-wave transmission through a fluid matrix with spherical inclusions that is modified to account for a two-fluid-phase matrix. Amplitude data as a function of NAPL fraction are described by assuming the distribution of NAPL in the column and using attenuation coefficients for the water-saturated and residual-water medium. Amplitudes are shown to be sensitive to both the fraction of NAPL and its distribution, whereas velocity is only a function of NAPL fraction.

The seismicity distribution and resulting seismic velocity structure, coupled with the known geology, are used to characterize the geothermal reservoir. The velocity structure is estimated using the progressive inversion technique of Thurber, (1983). Hypocenters within the CCSF lie between depths of 1.5 and 2.5 km and appear to be associated with the steam production zone. A deeper cluster of events is located beneath an injection well. High-velocity near-surface anomalies correspond to mapped sections of Franciscan metagraywacke and greenstone. Low-velocity anomalies at depth appear to represent sections of Franciscan melange. High Vp/Vs anomalies at depth suggest a recharge region or a condensation zone. The steam producing zone is marked by low Vp/Vs values, suggesting partial liquid saturation of the reservoir rocks.

Specifically, nonlinear-elastic fracture-mechanics tests were performed, as a function of displacement rate and temperature (-54 to 71 degree C), on center-cracked sheet test samples to determine fracture toughness in the form of J-integral resistance curves and viscoelastic resistance curves for the inert propellant H-24; in addition, in situ video imaging was employed to characterize the deformation and interaction between microstructural features and the crack-path morphology. It was found that at the lowest temperatures the increased polymer matrix strength resulted in enhanced cavitation and particle delamination, leading to larger crack-tip fracture process zones and hence to higher fracture toughness. At the high temperatures, the weaker polymer matrix was seen to tear readily and to advance the crack before significant particle delamination or cavitation would occur; this mechanism resulted in small fracture process zones and accounts for the decrease in fracture toughness with increasing temperature. The relationships between the toughness and fracture process in the material are discussed in terms of characterizing parameters for microstructural damage.

These issues of energy efficiency and fire safety are usually examined separately, but in this paper the interaction between these issues is discussed, with emphasis on reflective coatings. The important spectral ranges for radiant control are, in micrometers ( mu m), 0.3-2.5 (sunlight), 4-40 (300 K environmental thermal radiation) and 1-10 (fire). Benefits can be obtained from the development of improved coatings which reflect adverse energy flows and absorb (and emit) favorable energy flows. As a specific important example, white coatings with high solar reflectivity and high IR emissivity can significantly reduce energy use for cooling. Another benefit of high IR reflectivity in the 1-10 mu m wavelength range is enhanced fire safety due to the reflection of IR radiation emitted by fire. Due to overlap of the fire spectrum with both the solar and 300 K thermal spectra, fire retardant coatings can either enhance or impair energy performance. From a research and development point of view there is considerable synergism between coatings for improved energy efficiency and fire safety. Technology developed for improved energy efficiency can be adapted (transferred) to coatings for reflecting fire radiation, and vice versa.

To study the evolution of human breast cancer, a functionally relevant cell culture model is required which recognizes the complexity of the mammary gland's microenvironment. The development of an appropriate breast epithelial cancer cell model will be dependent on the ability to recreate the 'normal' and 'neoplastic' tissue microenvironment in culture. Towards this goal, a 3-dimensional extracellular matrix (ECM) assay, employing a reconstituted basement membrane, has been developed which allows for the rapid and accurate discrimination of normal and neoplastic cells when cultured. To investigate stromal/epithelial cell interactions, we have developed a tumor environment assay which essentially mirrors the tumor microenvironment histologically. The use of a novel, near diploid, human breast epithelial cell line, HMT-3522, which has transformed spontaneously with passage in culture, together with these 3-dimensional culture assays is expected to provide meaningful markers of initiation and progression.

To achieve the necessary selectivity and sensitivity, a method has been devised and tested for extraction and cleanup of gas- and particulate-phase ETS samples. Gas-phase species were trapped by polymeric sorbents, and particles were trapped on filters. The samples were extracted with hot cyclohexane, concentrated, and passed through silica solid-phase extraction columns for cleanup. After solvent change, the PAH were determined by high-performance liquid chromatography with two programmed fluorescence detectors. PAH concentrations in 15-mg aliquots of National Institute of Standards and Technology Standard Reference Material (SRM) 1649 (urban dust/organics) agreed well with published values.

The isotypic variety and conformational flexibility of tubulin have so far made it impossible to obtain crystals for X-ray work. Structural knowledge of tubulin has been limited to about 20 angstroms from X-ray diffraction of oriented microtubules, and from electron microscopy of microtubules and zinc-induced crystalline sheets in negative stain. The sheets consist of protofilaments similar to those in microtubules but associated in an antiparallel arrangement, and their two-dimensional character is ideal for high-resolution electron microscopy. Here we present a three-dimensional reconstruction of tubulin to 6.5 angstroms resolution, obtained by electron crystallography of zinc-induced two-dimensional crystals of the protein. The alpha - and beta -subunits appear topologically similar, in agreement with their sequence homology. Several features can be defined in terms of secondary structure. An apparent alpha -helical portion, adjacent to both interdimer and inter-protofilament contacts, is tentatively attributed to a segment near the carboxy terminus of the protein. We can assign the alpha - and beta -subunits on the basis of projection studies of the binding of taxol, which show one taxol site per tubulin heterodimer, in agreement with the known stoichiometry of taxol in microtubules. These studies indicate that taxol affects the interaction between protofilaments; to our knowledge, this is the first time that a ligand-binding site has been visualized in the tubulin molecule.

In the present study, Ceriodaphnia dubia toxicity tests were used to quantify toxicity of urban runoff at Crandall Creek and the downstream Demonstration Urban Stormwater Treatment (DUST) March in Fremont, California. Acute toxicity, expressed as the median time to lethality (LT50) for C. dubia, was used to compare the relative intensities of toxicity in the system. During or shortly after storm events, horizontal and vertical gradients in LT50 and electrical conductivity were observed, with high correlation between the two parameters. Toxicity diminished as time passed after the storm. The performance of the DUST Marsh as a treatment facility was evaluated for three aspects: detention, dilution, and toxicity removal. We found that toxic storm water generated by small- to medium-sized storms (5 to 25 mm rain) was contained in the marsh. Toxicity was greatly reduced upon dilution of storm water with pre-existing marsh water, and mixing of the water column increased the rate of toxicity diminution. Toxicity reduction, above and beyond that attributable to dilution, was evident in the marsh. Results of this study demonstrate the potential use of toxicity assessments as an integral component of marsh design and management.

Measurements for about 100 miners were performed, using filtered air samples to estimate their decay product exposures and a field gamma ray system to determine corresponding chest activities. These two quantities yielded the deposited lung activity per unit exposure, which is proportional to the product of the average minute volume and the fractional lung deposition, called here the 'filtration ability of lungs' (FAL). The group average FALs were found to be, for drillers, assistant drillers, and inspection personnel, respectively, 0.0079, 0.0067, and 0.0052 m super(3)/min, with approximately 20% standard error. Independent measurements were also made, for a group of mine workers engaged in light work, not only of FAL, but also of breathing rate (minute volume), permitting estimation of the lung deposition fraction, found to average 0.34 plus or minus 0.03. Finally, this value was used together with the group FALs noted to yield upper-bound estimates of the average minute volumes for these job categories, respectively, 0.023 plus or minus 0.004, 0.020 plus or minus 0.004, and 0.015 plus or minus 0.003 m super(3)/min.

Substitution of phenylalanine for tyrosine at position 160 (Y160F) showed 0.4% of the k sub(cat) of wild-type with isocitrate as substrate, while the K sub(m) for isocitrate remained unchanged. When the postulated intermediate, oxalosuccinate, was enzymatically decarboxylated, Y160F showed a higher k sub(cat) and a similar K sub(m) to the wild type values. The rate of reduction of oxalosuccinate to isocitrate by the Y160F mutant was greatly decreased relative to the wild-type. Substitution of methionine for lysine at position 230 decreased k sub(cat) to 1.1% of that of the wild-type and K sub(m) increased by a factor of 500-600. The decarboxylation of oxalosuccinate was undetectable for the K230M mutant. The structure of the site-directed mutants of IDH with and without a bound complex of isocitrate and Mg super(2+) was solved at 2.5 angstrom resolution and compared by difference mapping against previously determined enzyme structures. The structural studies show that (i) the overall protein-folding side chain conformations and active sites of both mutants are isomorphous with wild-type enzyme, (ii) isocitrate and magnesium bind to both enzyme mutants with the same relative conformation and binding interactions as wild-type enzyme, and (iii) the mutated side chains (Phe 160 and Met 230) are positioned for catalysis in a similar conformation as that observed for the wild-type enzyme. Hence, the alteration of the side chain functional groups is directly related to the loss of enzyme activity. Possible roles of the active site tyrosine and lysine are discussed.

Based on numerical predictions, installation of a sub gravel membrane at the study site resulted in a factor of 2 reduction in indoor radon concentrations. Experimental data indicated that installation of "short-circuit" pipes extending between the subslab gravel and outdoors caused an additional factor of 2 decrease in the radon concentration. Consequently, the combination of these two passive radon mitigation features, called the membrane and short-circuit (MASC) technique, we associated with a factor of 4 reduction in indoor radon concentration. The energy-efficient active radon mitigation method, called efficient active subslab pressurization (EASP), required only 20% of the fan energy of conventional active subslab depressurization and reduced the indoor radon concentration by approximately a factor of 15, including the numerically-predicted impact of the sub-gravel membrane.

The regulations also permit electric utilities to earn emission allowances through conservation programs. The utility may verify the savings with "Conservation Verification Protocols (CVPs)". Use of the CVPs encourages monitoring and establishes a consistent procedure for evaluating electricity savings in all sectors and electrical end uses. In limited cases where the energy savings can be reliably predicted, the CVPs are used to stipulate savings or a procedure to calculate them. The CVPs represent new concepts, including a procedure for linking the amount of savings to confident that they occurred and a flexible approach to estimation of subsequent-year energy savings.

Various device types such as p-i-n, n-i-n and n-i-p-i-n structures were fabricated and tested. Photoconductive gain was measured in two time scales: one for short pulses of visible light (< 1 mu sec) which simulates the transit of an energetic charged particle, and the other for rather long pulses of light (1 msec) which simulates x-ray exposure in medical imaging. We used two definitions of photoconductive gain: current gain and charge gain which is an integration of the current gain. We found typical charge gains of 3 approx. 9 for short pulses and a few hundred for long pulses at a dark current level of 10 mA/cm super(2). Various gain results are discussed in terms of the device structure, applied bias and dark current. JF - Materials Research Society Symposium Proceedings. Vol. 377, pp. 767-772. 1995.

Conflicting and unwise use has led to problems of groundwater contamination. Cleanup is often difficult and expensive, and perhaps not even possible in many cases. Construction projects often encounter unanticipated difficulties that increase expenses. Many of the difficulties of predicting mechanical behavior and fluid flow and transport behavior stem from problems in characterizing what cannot be seen. An underground research laboratory, such as can be developed in the nearly 14 miles of tunnel at the Superconducting Super Collider (SSC) site, will provide a unique opportunity to advance scientific investigations of fluid flow, chemical transport, and mechanical behavior in situ in weak and fractured, porous rock on a scale relevant to civil and environmental engineering applications involving the subsurface down to a depth of 100 m. The unique element provided by underground studies at the SSC site is three-dimensional access to a range of fracture conditions in two rock types, chalk and shale. Detailed experimentation can be carried out in small sections of the SSC tunnel where different types of fractures and faults occur and where different rock types or contacts are exposed. The entire length of the tunnel can serve as an observatory for large scale mechanical and fluid flow testing. The most exciting opportunity is to mine back a volume of rock to conduct a post-experiment audit following injection of a number of reactive and conservative tracers. Flow paths and tracer distributions can be examined directly. The scientific goal is to test conceptual models and numerical predictions. In addition, mechanical and hydrological data may be of significant value in developing safe and effective methods for closing the tunnel itself.

This allows one to use nonlinear programming and simulated annealing techniques to solve groundwater management problems, i.e. the optimization of multiphase aquifer remediation. This report contains three illustrative examples to demonstrate the optimization of remediation operations by means of simulation-minimization techniques. The code iteratively determines an optimal remediation strategy (e.g. pumping schedule) which minimizes, for instance, pumping and energy costs, the time for cleanup, and residual contamination. While minimizing the objective function is straightforward, the relative weighting of different performance measures--e.g. pumping costs versus cleanup time versus residual contaminant content--is subject to a management decision process. The intended audience of this report is someone who is familiar with numerical modeling of multiphase flow of contaminants, and who might actually use T2VOC in conjunction with ITOUGH2 to optimize the design of aquifer remediation operations.

This requires identifying grouts, or barrier fluids, which when injected into the subsurface exhibit a large increase in viscosity and eventually solidify, sealing the permeable zones in the aquifer. Simulation and modeling analysis are indispensable tools for designing the injection and predicting the performance of the barrier. In order to model flow and transport in such systems, the thermophysical properties of the fluid mixtures have to be provided, and the governing mass- and energy-balance equations for multiphase flow in porous media have to be solved numerically. The equation-of-state module EOS11 described herein is an extension of the EOS7 module of the TOUGH2 code for flow of saline water and air. In the modeling approach, the chemical grout is treated as a miscible fluid the viscosity of which is a function of time and concentration of the gelling agent in the pore water. If a certain high viscosity is reached and the movement of the grout plume ceases, the gel is assumed to solidify, leading to a new porous medium with changed soil characteristics, i.e. reduced porosity and permeability, increased capillary strength for a given water content, and changed initial saturation distribution.

In this work the fields from a low frequency vertical magnetic dipole have been examined from the specific point of view of their application to the determination of the conductivity of a layered medium. The source and the receiver were placed inside two separate boreholes. The range of penetration of such a crosswell system for typical earth resistivities and for currently available transmitter and receiver technologies was found to be up to 1,000 meters so problems in ground water and petroleum reservoir characteristics can be practically examined. An analysis of the behavior of the magnetic fields at the boundary between two half-spaces showed that the horizontal magnetic field component, H(rho ), and the vertical derivative of a vertical component, delta H (sub z) /delta z, are more sensitive to conductivity variations than H (sub z) . The analysis of derivatives led to the concept of measuring the conductivity directly using a second vertical derivative of H (sub z) . Conductivity profiles interpreted from field data using this technique reproduced accurately the electrical logs for a test site near Devine, Texas. It was found in this study that the inversion techniques are more stable when the first vertical derivative of H (sub z) is used rather than H (sub z) itself. Using data from a salt water injection experiment at the Richmond Field test site in Berkeley it was also found that these robust layer inversions were successful in identifying the preferential flow direction of the injected brine to four boreholes surrounding the injection well.

The CsI(Tl) layers range in thickness from 65 to 220 mu m. We used the two-boat evaporator system to deposit CsI(Tl) layers. This system ensures the formation of the scintillator film with homogenous Tl concentration which is essential for optimizing the scintillation light emission efficiency. The Tl concentration was kept to 0.1-0.2 mole % for the highest light output. Temperature annealing can affect the microstructure as well as light output of the CsI(Tl) film. 200-300C super(0) annealing can increase the light output by a factor of two. The amorphous silicon pixel arrays are p-i-n diodes approximately 1 mu m thick with transparent electrodes to enable them to detect the scintillation light produced by X-rays incident on the CsI(Tl). Digital radiography requires a good spatial resolution. This is accomplished by making the detector pixel size less than 50 mu m. The light emission from the CsI(Tl) is collimated by techniques involving the deposition process on pattered substrates. We have measured MTF of greater than 12 line pairs per mm at the 10% level.

Recent research to evaluate relationships between genotoxic responses and indicators of reproductive success in model animals is described from an ecotoxicological perspective. Genotoxicity can be correlated with reproductive effects such as gamete loss due to cell death; embryonic mortality; and heritable mutations in a range of model animals including polychaete worms, nematodes, sea urchins, amphibians, and fish. In preliminary studies, the polychaete worm, Neanthes arenaceodentata, and the nematode, Caenorhabditis eleqans, have also shown the potential for cumulative DNA damage in gametes. If DNA repair capacity is limited in gametes, then selected life history traits such as long and synchronous periods of gametogenesis may confer vulnerability to genotoxic substances in chronic exposures. Recommendations for future research include strategic development of animal models that can be used to elucidate multiple mechanisms of effect (multiend point) at varying levels of biological organization (multilevel).

We present here a synthesis of the ideas discussed throughout the conference, including definitions of important concepts in the field and critical research needs and opportunities. While there were many opinions expressed on these topics, there was general agreement that there are substantive new opportunities to improve the impact of genetic and molecular ecotoxicology on prediction of sublethal effects of exposure to hazardous substances. Future studies should emphasize integration of genetic ecotoxicology, ecological genetics, and molecular biology and should be directed toward improving our understanding of the ecological implications of genotoxic responses. Ecological implications may be assessed at either the population or ecosystem level; however, a population level focus may be most pragmatic. Recent technical advancements in measuring genetic and molecular responses to toxicant exposure will spur rapid progress. These new techniques have considerable promise for increasing our understanding of both mechanisms of toxicity on genes or gene products and the relevance of detrimental effects to individual fitness.

Sensitivity and selectivity were enhanced by analyzing PAHs under their optimum fluorescence wavelengths. The accuracy of the analytical method was evaluated by determination of PAHs in 5 mg of standard reference material SRM 1649. The method was also successfully employed to analyze major parent PAHs and some alkyl-PAHs from environmental tobacco smoke [ETS] with a sample size of 2 mg using class-selective fluorescence wavelengths. Some alkyl-PAHs were tentatively identified even in the absence of standard compounds. Coeluting pairs were identified and analyzed by careful selection of excitation and emission wavelengths for each compound. Identities of the signals were confirmed by comparing both the retention behavior and the peak-height ratios at two or more different excitation and emission wavelength combinations.

Two separate groups of model parameter derivations were obtained, depending on which data sets were being fitted. The model was then used to simulate five environmental or occupational exposures. Predicted values of the total bone marrow exposure to benzene and cumulative quantity of metabolites produced by the bone marrow were generated for each scenario. The relation between cumulative quantity of metabolites produced by the bone marrow and continuous benzene exposure was also investigated in detail for simulated inhalation exposure concentrations ranging from 0.0039 ppm to 150 ppm. At the level of environmental exposures, no does rate effect was found for either model. The occupational exposures led to only slight dose rate effects.

We report here that transcription of genes encoding 16 S rRNA, a stable RNA species, or cytoplasmic polypeptides leads to very little or no detectable DNA supercoiling even under the optimum conditions in Escherichia coli. This indicates that hydrodynamic drag on the transcription complex (including RNA polymerase, nascent RNA, ribosomes, and nascent polypeptides) is not sufficient to anchor RNA polymerase during coupled transcription-translation. On the other hand, transcription of membrane-associated genes encoding integral inner membrane or exported periplasmic polypeptides leads to apparent DNA supercoiling. Transcription of genes encoding integral inner membrane polypeptides leads to significantly greater anchoring of RNA polymerase than does transcription of genes encoding periplasmic polypeptides. polypeptide. This may reflect differences in the coupling of transcription-translation with membrane association during expression of these two classes of polypeptides. Evidence is further presented to suggest that the anchoring of RNA polymerase is probably achieved through the interaction of nascent polypeptides with the cytoplasmic surface of the inner membrane during coupled transcription-translation. Moreover, transcription of a membrane-associated gene can, under certain circumstances, induce topological anchoring of an RNA polymerase transcribing a neighboring gene that ordinarily is not membrane-associated. Finally, the potential biological consequences of our findings are discussed. JF - Journal of Biological Chemistry AU - Ma, D AU - Cook, D N AU - Pon, Ning G AU - Hearst, JE AD - Dep. Chem., Univ.

Planners are not prepared to deal with the pace of motorization caused by the startling speed of urbanization and growth of disposable income. In addition, planning responses have been constrained by inadequate resources, inappropriate administrative and institutional arrangements for urban management and lack of expertise, all in the face of competing demands for resources elsewhere in the public sector. This article highlights some of the general transportation trends in Asian cities and discusses some of the possible institutional solutions for improving these urban transport systems.

In this new design the photomultiplier tubes and the position sensing circuitry are replaced by 2D array of a-Si:H p-i-n pixel photodetectors and readout circuitry which are built on a substrate. Without the photomultiplier tubes this camera is light weight, hence can be made portable. To predict the characteristics and the performance of this new gamma camera we did Monte Carlo simulations. In the simulations 128 x 128 imaging array of various pixel sizes were used. super(99m)Tc (140 keV) and super(201)Tl (70 keV) were used as radiation sources. From the simulations we could obtain the resolution of the camera and the overall system, and the blurring effects due to scattering in the phantom. Using the Wiener filter for image processing, restoration of the blurred image could be achieved. Simulation results of a-Si:H based gamma camera were compared with those of a conventional gamma camera. JF - Proceedings of SPIE - The International Society for Optical Engineering.

To date, little has been published about the connectivity of this area to the rest of the geothermal field, the interaction between the so-called "typical" reservoir and the underlying high-temperature zone, or the combined potential of both producing horizons. To investigate these issues, a dual-porosity numerical model of The Geysers geothermal system with special emphasis to the NW Geysers was developed. The model was calibrated using production data from 1957 to early 1991. Simulation results and the measured data suggest that: the typical reservoir in NW Geysers is connected to the rest of the field; significant migration of fluids from this part of the reservoir to the rest of The Geysers has occurred; and there still are some undeveloped areas in the NW Geysers with production potential. The production/injection scenarios analyzed with the model suggest that the existing wells are not sufficient to sustain a 60 MWe operation for 30 years starting in 1991. However, the addition of new wells within the licensed boundaries of the Coldwater Creek steamfield, drilled over a period of years, could sustain the steam production required to generate 60 MWe for 30 years. A 130 MWe development is not feasible within the mid-1993 licensed boundaries.

We describe a method using logarithms of probabilities based on seventh-order Markov chains to rapidly identify genomic sequences that do not resemble models of genome organization built from compilations of octanucleotide usage. Data bases have been constructed from Escherichia coli and Saccharomyces cerevisiae DNA sequences of > 1000 nt and human sequences of >10,000 nt. Atypical genes and clusters of genes have been located in bacteriophage, yeast, and primate DNA sequences. We consider criteria for statistical significance of the results, offer possible explanations for the observed variation in genome organization, and give additional applications of these methods in DNA sequence analysis.

The studies revealed that isomerization of isorhodopsin was three times slower than that of rhodopsin indicating the significant role of the 13-methyl group in catalyzing the torsional motion. The quantum yield for isorhodopsin at 0.22 was also threefold lower than for rhodopsin at 0.67. This implied that quantum yield was directly proportional to the torsional motion speed.

We have developed a direct colorimetric detection method based on a polymeric bilayer assembly. The bilayer is composed of a self-assembled monolayer of octadecyl siloxane and a Langmuir-Blodgett layer of polydiacetylene. The polydiacetylene layer is functionalized with receptor-specific ligands such as analogs of sialic acid. The ligand serves as a molecular recognition element, while the conjugated polymer backbone signals binding at the surface by a chromatic transition. The color transition is readily visible to the naked eye as a blue to red color change and can be quantified by visible absorption spectroscopy. The color transition can be inhibited by the presence of soluble inhibitors. Raman spectroscopic analysis shows that the color transition may arise from binding induced strain on the material resulting in bond elongation and conjugation length reduction.

The genes encoding many carotenoid biosynthetic pathways have now been mapped and cloned in several different species, and the availability of cloned genes which encode the biosynthesis of carotenoids not found in the photosynthetic genus Rhodobacter opens up the possibility of introducing a wider range of foreign carotenoids into the bacterial photosynthetic apparatus than would normally be available by producing mutants of the native biosynthetic pathway. For example, the crt genes from Erwinia herbicola, a gram-negative nonphotosynthetic bacterium which produces carotenoids in the sequence of phytoene, lycopene, beta -carotene, beta -cryptoxanthin, zeaxanthin, and zeaxanthin glucosides, are clustered within a 12.8-kb region and have been mapped and partially sequenced. In this paper, part of the E. herbicola crt cluster has been excised and expressed in various crt strains of Rhodobacter sphaeroides. This has produced light-harvesting complexes with a novel carotenoid composition, in which the foreign carotenoids such as beta -carotene function successfully in light harvesting. The outcome of the combination of the crt genes in R. sphaeroides with those from E. herbicola has, in some cases, resulted in an interesting rerouting of the expected biosynthetic sequence, which has also provided insights into how the various enzymes of the carotenoid biosynthetic pathway might interact. Clearly this approach has considerable potential for studies on the control and organization of carotenoid biosynthesis, as well as providing novel pigment-protein complexes for functional studies.

Advantages of this method include (i) the ability to obtain tensiometer measurements far beyond the approximately 9 m-depth often associated with the limit of conventional tensiometry, (ii) ease of regular gauge calibration, and (iii) low cost. Advantages relative to buried, dedicated pressure transducer tensiometers are gained at the expense of substantial losses in gauge sensitivity, S*. In view of this compromise, an analysis was performed to determine the optimal fractional water-filled length, F, for air pocket tensiometers. It is shown that the critical ratio governing the nature of S*-optimization is approximated by (II* -II sub(0))z*, where II* represents the absolute matric head, II sub(0) is the vapor pressure of water expressed in head units, and z* is the depth of the tensiometer tip. When (II* - II sub(0))/z* > 1, S* is optimized when F arrow right 1. However, when (II* - II sub(0))/z* < 1, S* is optimized as F arrow right 0. The central role of (II* - II sub(0))/z* arises from the fact that S* = P sub(a)/V sub(g), where P sub(a) refers to the absolute pressure of all tensiometer headspace gases excluding water vapor, and V sub(g) refers to the volume of the gas phase within the tensiometer headspace. When (II* - II sub(0)) is less than z*, S* goes to zero because the absolute pressure in the tensiometer headspace approaches the vapor pressure of the tensiometer water (P sub(o)) when attempts are made to fill the tensiometer column with liquid water. In the more familiar case of II* - II sub(0) being larger than z*, the dominance of P sub(a) over P sub(o) assures that S* increases as the instrument is filled. To test the predicted nature of S*, laboratory experiments were performed on 1.11-, 6.36-, and 11.91-m long tensiometers over a range of values of (II* - II sub(0)) and F sufficient to provide three orders of magnitude variation in S*. Measured S* agreed well with predicted values, and supports the conclusion that response times are minimized with F arrow right 0, in situations where (II* - II sub(0))/z* < 1.

Selenium loads appear to be reduced by between 25% and 35% while in-transit between the south and north boundaries of the District leading to concern about the fate of this selenium. A study was conducted to identify biological and biochemical mechanisms that could account for possible uptake, immobilization and volatilization of selenium in the Grassland system. The study also attempted to discriminate between natural processes and anthropogenic factors that might explain the seasonal and year to year variations observed in the selenium monitoring data. Isolates from the water column revealed certain aerobic and facultative bacteria that are effective at removing selenite from solution. A preliminary model using the STELLA super(TM) programming language has been developed to explore the relative importance of candidate biological and biochemical mechanisms responsible for the observed in-transit selenium load reduction.

Results of this monitoring program indicate that the soil selenium inventory at Kesterson may be categorized in terms of three main patterns: (1) spatial trends associated with historic Reservoir operations; (2) temporal trends due to the oxidation and remobilization of the selenium inventory and; (3) temporal trends due to seasonal cycles. It is evident that the selenium inventory and distribution within the soil profile will evolve slowly whereby the fraction of the total inventory that is now immobile (est. at 93%) will oxidize to more mobile and bioavailable forms.

Among them, the histidine-binding protein (HisJ) has been extensively studied from the biochemical, physiological, and genetic points of view. The three-dimensional crystal structure of the histidine-binding protein complexed with histidine has been determined at 2.5-angstrom resolution by the molecular replacement method using as a probe structure the previously solved lysine-liganded structure of the lysine-, arginine-, ornithine-binding protein (LAO), which shares 70% sequence identity with HisJ. The structure is bi-lobate; the two lobes, one bigger than the other, are connected by two short strands and are in contact with each other (closed) enclosing the histidine. Charged, polar, and non-polar side chains, as well as the peptide backbone, are involved in tight binding of the histidine. The bound histidine is involved in eight direct hydrogen bonds, six with the bigger lobe and two with the smaller lobe, in one potential water-mediated hydrogen bond with the bigger lobe, as well as in ionic interactions. The HisJ residues surrounding the ligand are the same as the LAO residues interacting with lysine, except for residue 52 which is leucine in HisJ and phenylalanine in LAO. The Leu-52 in HisJ makes a hydrophobic interaction with the imidazole ring of histidine. Of seven mutations affecting the ligand-binding site, five are located in the ligand-binding site, one in a connecting strand, and one at the domains interface. Based on comparisons among related binding proteins, the specific interactions between the ligands and the respective binding protein residues are predicted for the glutamine-binding protein and the opines-binding protein.

A two-dimensional porous-slab model was used with a non-uniform heat flux boundary condition at the bottom. Steady-state solutions are obtained for the phase distribution and heat transfer behavior for cases with different mass of fluid (gas saturation) in place, permeabilities, and capillary pressures. The results obtained show very efficient heat transfer in the vapor-dominated zone due to the development of heat pipes and near-uniform saturations. The phase distribution below the vapor-dominated zone depends on permeability. For relatively high-permeability systems, single-phase liquid zones prevail, with convection providing the energy throughput. For lower permeability systems, a two-phase liquid-dominated zone develops, because single-phase liquid convection is not sufficient to dissipate heat released from the source. These results are consistent with observations from the field, where most high-temperature liquid-dominated two-phase systems have relatively low permeabilities (e.g. Krafla, Iceland; Olkaria, Kenya; Baca, New Mexico). The numerical results obtained also show that for high heat flow a high-temperature single-phase vapor zone can develop below a typical (240 degree C) vapor-dominated zone, as has recently been found at The Geysers, California, and Larderello, Italy.

The C57BL/6 strain differs from most inbred strains by having lower HDL concentrations and a high risk of developing early atherosclerotic lesions when fed an atherogenic diet. The relative HDL deficiency and atherosclerosis susceptibility of the C57BL/6 strain are corrected with the expression of a human apolipoprotein AI (apo AI) transgene in this genetic background. To examine if increases in apo AI and HDL are also effective in minimizing apo E deficiency-induced atherosclerosis, we introduced the human apo AI transgene into the hypercholesterolemic apo E knockout background. Similar elevations of total plasma cholesterol occurred in both the apo E knockout and apo E knockout mice also expressing the human apo AI transgene. The latter animals, however, also showed a two- to threefold increase in HDL and a sixfold decrease in susceptibility to atherosclerosis. This study demonstrates that elevating the concentration of apo AI reduces atherosclerosis in apo E deficient-mice and suggests that elevation of apo AI and HDL may prove to be a useful approach for treating unrelated causes of heightened atherosclerosis susceptibility.

This method reacts yellow phosphorus with O sub(2) in moist air to produce species such as O, O sub(3), PO, and PO sub(2), which are capable of reacting with various types of organics. Toxic organic compounds are converted to small molecular weight organic acids, aldehydes, and/or alcohols, while yellow phosphorus is oxidized into phosphoric acid, which may be recovered as a valuable byproduct.

Our results show that CNN number concentrations (measured at 0.5% supersaturation) and nss SO sub(4) super(2-) mass concentrations (in the range of similar to 400-1700 ng/m super(3)) are significantly correlated at this site. Droplet concentrations in the cumulus clouds studied do not show a discernible trend with nss SO sub(4) super(2-) mass concentrations (in the range of similar to 300-1400 ng/m super(3)). In stratocumulus clouds, a small increase in droplet concentration with nss SO sub(4) super(2-) mass concentrations in the range of similar to 300-1100 ng/m super(3) was observed. We attribute the low sensitivities of the droplet number concentrations to nss SO sub(4) super(2-) mass concentrations to the entrainment/mixing processes in these clouds. The magnitudes of the empirically derived sensitivities are considerably lower than those assumed in recent assessments of the effect of anthropogenic sulfate aerosols on cloud albedo. JF - Tellus.

The model assumes that the VOCs originate predominantly in a uniform slab of polymer backing material. Parameters for the model (the initial concentration of a VOC in the polymer, a diffusion coefficient and an equilibrium polymer/air partition coefficient) are obtained from experimental data produced by a previous chamber study. The diffusion coefficients generally decrease as the molecular weight of the VOCs increase, while the partition coefficients generally increase as the vapor pressure of the compounds decreases. In addition, for two of the study carpets that have a styrene-butadiene rubber (SBR) backing, the diffusion and partition coefficients are similar to independently reported values for SBR. The results suggest that prediction of VOC emissions from new carpets may be possible based solely on a knowledge of the physical properties of the relevant compounds and the carpet backing material. However, a more rigorous validation of the model is desirable. JF - Atmospheric Environment AU - Little, J C AU - Hodgson, A T AU - Gadgil, A J AD - Energy and Environ.

However, the practicing design professional still encounters a large gap between theory and practice when faced with a complex, novel fire protection problem. The first article in this two-part series illustrates the general approach used by a consulting fire protection engineering firm to develop a set of practical fire safety requirements for a situation which lacks any direct pre-existing code guidance--the modification of a bus facility to accommodate vehicles fueled by natural gas. The second article reviews the analysis and the requirements proposed by the authors' consulting firm for a typical natural gas bus facility.

Resting cells of hydrophilic and relatively hydrophobic bacterial strains isolated from groundwater were used as model microorganisms. The degree of hydrophobicity was determined by contact-angle measurements. Glass micromodels allowed the direct observation of bacterial behavior on a pore scale, and three types of sand columns with different gas saturations provided quantitative measurements of the observed phenomena on a porous medium scale. The reproducibility of each breakthrough curve was established in three to five repeated experiments. The data collected from the column experiments can be explained by phenomena directly observed in the micromodel experiments. The retention rate of bacteria is proportional to the gas saturation in porous media because of the preferential sorption of bacteria onto the gas-water interface over the solid-water interface. The degree of sorption is controlled mainly by cell surface hydrophobicity under the simulated groundwater conditions because of hydrophobic forces between the organisms and the interfaces. The sorption onto the gas-water interface is essentially irreversible because of capillary forces. This preferential and irreversible sorption at the gas-water interface strongly influences the movement and spatial distribution of microorganisms.

The goal of PA is to assess, as far quantitatively as possible, whether radioactive contaminants will be released to the groundwater and transported to the accessible environment in adverse quantities should a potential repository for high level radioactive wastes (HLW) be constructed and operated at Yucca Mountain. Ideally, it would be desirable to demonstrate with certitude, using scientific data, that the wastes could be safely contained at the site over a 10,000-year time frame. Nevertheless, the scientific issues involved are many and the necessary data cannot be gathered and interpreted over the next several years to answer all the questions. Yet, available evidence suggests that the site has many attributes favorable for long-term containment of high level radioactive wastes. Under the circumstances, a phased, long-term approach to site characterization appears prudent. Integral to such an approach will be long-term data acquisition and monitoring, should construction be permitted. Considering the complex, difficult-to-access nature of earth systems, the long-term approach should provide for an open-endedness to accommodate unforeseen contingencies which may come to light during long-term monitoring. To guide data acquisition and monitoring, it is necessary to identify the various technical issues relevant to repository performance. We present these issues in a systematic, hierarchial frame-work.

Fluid flow between the fracture network and the matrix blocks is described by analytical expressions that have been derived from approximate solutions to the imbibition equation. These expressions have been programmed into an unsaturated flow simulator, TOUGH, as a source/sink term. Flow processes are then simulated using only fracture elements in the computational grid. The modified code is used to simulate flow along single fractures, and infiltration into pervasively fractured formations. Comparisons are made with simulations carried out using discretization of both the fractures and matrix blocks. The new semi-analytical code is shown to be accurate, and typically requires an order of magnitude less computational time.

The objectives were to characterize indoor air exposures to VOCs, to investigate variations in chemical composition and concentrations among the buildings, and to identify potential sources of the VOCs. Indoor TVOC concentrations ranged from 230 to 7000 mu g m super(-3) with a geometric mean of 510 mu g m super(-3). The highest TVOC concentrations were measured in two buildings with wet-process photocopiers. Geometric mean concentrations of individual VOCs were, with one exception, less than 5 ppb. There was considerable variation in the chemical composition of the VOC mixtures among the buildings. For most buildings, the oxidized hydrocarbons were the dominant class. Factor analysis identified motor vehicle emissions from outdoor air as a major source of seven aromatic and five alkane hydrocarbons. There was evidence of freon leaking from air conditioning or refrigeration systems in several of the buildings.

This site-scale model covers an area of about 30 km super(2) and is bounded by major faults to the east and west. A detailed numerical grid has been developed based on the locations of boreholes, on the spatial distribution of different infiltration zones, hydrogeological units and water level data, and on the offset of the volcanic tuffs due to major faults. Hydrogeologic contour- and isopachs maps, are presented for the different infiltration zones, and for the base of the Tiva Canyon, the Paintbrush, and the Topopah Spring hydrogeological units. One- and two-dimensional simulations have been performed using the TOUGH2 computer code to test the geometry and the accuracy of the model-grid, which consists of about 5000 gridblocks distributed among 17 non-uniform vertical layers representing the four main hydrogeological units of the unsaturated zone.

The deduced amino acid sequence is similar to that of the low-affinity PDEase of S. cerevisiae (PDE1) and the cyclic nucleotide PDEase (PD) of Dictyostelium discoideum. Biochemical analysis of recombinant protein produced in S. cerevisiae indicated that the enzyme behaves as a PDE1 homologue: it hydrolyses both cAMP (K sub(m) = 0.49 mM) and cGMP (K sub(m) = 0.25 mM), does not require divalent cations for maximal activity and is only moderately inhibited by millimolar concentrations of standard PDEase inhibitors. Based on these data, we designate the C. albicans we have cloned, PDE1. Low-stringency genomic Southern blots showed cross-hybridization between C. albicans PDE1 and DNA from Candida stellatoidea, but not with DNA from S. cerevisiae or several closely related Candida species.

Lesion conversion was thought to occur during the initial round of DNA replication or as a consequence of error-prone enzymatic processing of lesions. The standard experimental protocols for the assessment of a variety of radiation-induced endpoints (cell death, specific locus mutations, neoplastic transformation and chromosome aberrations) evaluate these various endpoints at a single snapshot in time. In contrast with the aforementioned approaches, some studies have specifically assessed radiation effects as a function of time following exposure. Evidence has accumulated in support of the hypothesis that radiation exposure induces a persistent destabilization of the genome. This instability has been observed as a delayed expression of lethal mutations, as an enhanced rate of accumulation of non-lethal heritable alterations, and as a progressive intraclonal chromosomal heterogeneity. The genetic controls and biochemical mechanisms underlying radiation-induced genomic instability have not yet been delineated. The aim is to integrate the accumulated evidence that suggests that radiation exposure has a persistent effect on the stability of the mammalian genome.

Normal development and cytogenetic effects (anaphase aberrations) were assessed after the cultures were allowed to develop for 48 h. Using radiolabeled chemicals, we also characterized concentrations in the test water as well as doses in the embryos following 2- and 48-h exposures. We observed dose responses for all chemicals and all responses, except for phenol, which showed no significant effect on development. Fertilization success was never the most sensitive end point. Anaphase aberrations were the most sensitive response for phenol, with an LOEC of 2.5 mg/L exposure concentration. Anaphase aberrations and development were equivalent in sensitivity for benzidine within the tested dose range, and an LOEC of <0.1 mg/L was observed. Development was the most sensitive response for pentachlorophenol (LOEC 1 mg/L). The LOEC values for this study were generally lower than comparable data for aquatic life or human health protection. We conclude that genotoxicity and development evaluations should be included in environmental management applications and that tests developed primarily for human health protection do not reliably predict the effects of toxic substances on aquatic life.

Since the geologic media are heterogeneous and their details can never be known deterministically, long-term prediction of flow and transport in such systems requires new thinking. Thus, it is no longer possible to consider site characterization and predictive modeling calculations to be separate activities; rather they are highly coupled. This paper presents a discussion of the coupling and proposes a framework of technical issues that need to be studied.

Using other polymerases for complete replication, but with limiting enzyme, a pause site before the m super(4)T was observed. In order to investigate whether such a pause could be due to enzyme dissociation or stalling, trapping experiments were designed to aid in differentiating the two mechanisms. Rather than the generally used heparin or sheared DNA trap, these experiments utilized as the acceptor the same oligonucleotide containing unmodified thymine. It was observed that, under enzyme-limiting conditions, the nature of the enzyme played a major role in replication of m super(4)T. With a running start, Kf and calf-thymus polymerase alpha -primase allowed replication beyond the m super(4)T, while Sequenase and T7 showed a strong pause site at the base before m super(4)T. When the oligonucleotide trap was added after different times of replication, it was found that Sequenase remained bound to the template-primer, regardless of whether T or m super(4)T was present. In contrast, Kf dissociated and re-associated rapidly. Thus, m super(4)T appears to be a strong replication block when using limiting amounts of a highly processive enzyme such as Sequenase or T7. This may imply that such enzymes discriminate against forming a poor basepair but remain bound to the primer-template or become inactivated.

The experiments were performed with a laboratory cloud chamber at conditions corresponding to the phase-mixed reaction regime, when the apparent reaction order with respect to NO sub(2) should reflect the aqueous-phase reaction order. Parallel measurements with water bubblers were performed under conditions favoring the mass transport controlled regime. Our results show that the reaction is first order with respect to gaseous NO sub(2) for both reaction regimes. These results differ from results obtained by other workers from experiments with a bulk water system (Lee and Schwartz, 1981), which showed reaction orders of 2 and 1, respectively, for the two regimes. Our results also demonstrate that NO sub(2) reaction with acidified cloud droplets should be a source of gaseous HONO. Finally, we present preliminary evidence of a possible synergism between HNO sub(3) and the uptake and oxidation of NO sub(2) in cloud droplets.

The sampling site received marine fog advected from the San Francisco Bay. Samples of ambient particulate material (total aerosol) were collected using a filter sampler with a heated inlet. Concentrations of Na super(+), K super(+), NH super(+) sub(4), Cl super(-), NO super(-) sub(3), and SO sub(4) super(2-) were measured in the particles and fog water, for which pH was also measured. Black carbon aerosol was determined on the filter samples using optical attenuation. The marine fog showed the influence of mixing and chemical reaction with anthropogenic pollutants. Twenty-six percent of the black carbon wsa present in fog droplets, indicating that incorporations of combustion particles into fog droplets had occurred. Anthropogenic particulate species were not scavenged by fog water as efficiently as sea-salt components. Non-sea-salt SO sub(4) super(2-) was enhanced in the total aerosol during fog compared to dry conditions, and this observation has been interpreted as evidence for heterogeneous production of SO sub(4) super(2-) in fog. The fog had elevated SO sub(4) super(2-) and NO sub(3) super(-)levels compared to sites closer to the ocean. Sufficient NH sub(3)(g) was available to neutralize the increased acidity from anthropogenic H sub(2)SO sub(4) and HNO sub(3) so that the median pH was 4, as compared to pH 2.2 observed in Los Angeles fog water under more polluted conditions. Loss of Cl super(-) from the fog or its precursor aerosol was enhanced compared to other measurements of San Francisco Bay Area fog at more remote locations.

The model is based on McMillan-Mayer solution theory and the generalized mean-spherical approximation to account for electrostatic forces between unlike ions. The Boublik-Mansoori equation of state for hard-sphere mixtures is coupled with the osmotic virial expansion truncated after the second-virial terms to account for short-range forces between molecules. Osmotic second virial coefficients are reported from low-angle laser-light scattering (LALLS) data for binary and ternary aqueous solutions containing polymers and proteins. Ion-polymer specific-interaction coefficients are determined from osmoticpressure data for aqueous solutions containing a water-soluble polymer and an alkali chloride, phosphate or sulfate salt. When coupled with LALLS and osmotic-pressure data reported here, the model is used to predict liquid-liquid equilibria, protein partition coefficients, and electrostatic potentials between phases for both polymer-polymer and polymer-salt aqueous two-phase systems. For bovine serum albumin, lysozyme, and alpha -chymotrypsin, predicted partition coefficients are in excellent agreement with experiment.

AN - 745650864; 73051 AB - The primary event in vision, the cis-trans isomerization of rhodopsin, is resolved with the use of 10 fs blue-green optical pulses. Rhodopsin 11-cis is excited with a 35 fs pump pulse at 500nm, and the transient changes in absorption are measured from 450 to 620 nm using a 10 fs probe pulse at 500 nm, and a 10 fs probe pulse at 620 nm. Within 200 fs, an increased absorption is observed between 550 and 620 nm, indicating the formation of photoproduct on this scale. These measurements demonstrate that the first step in vision is essentially complete in only 200 fs. JF - SPRINGER-VERLAG GMBH & COMPANY KG, BERLIN 33 (GER). 1993.

The system approaches the segmentation problem by assigning each volumetric region to anatomical structure. This is accomplished by satisfying constraints at the pixel level, slice level, and volumetric level. Each slice is represented by an attributed graph, where nodes correspond to regions and links correspond to the relations between regions. These regions are obtained by grouping pixels based on similarity and proximity. The slice level attributed graphs are then coerced to form a volumetric attributed graph, where volumetric consistency can be verified. The main novelty of our approach is in the use of the volumetric graph to ensure consistency from symbolic representations obtained from individuals slices. In this fashion, the system allows errors to be made at the slice level, yet removes them when the volumetric consistency cannot be verified. Once the segmentation is complete, the 3D surfaces of the brain can be constructed and visualized. JF - IEEE, PISCATAWAY, NJ, (USA). pp. 615-616. 1993.

Previously published data, taken in a laboratory environmental chamber, are segregated by sex to test for differences between men and women. These tests indicate a statistically significant difference between the skin temperature responses of men and women to physical activity under thermally neutral conditions, as well as a statistically significant difference in their surface-area-normalized evaporative heat loss. The optimal skin temperatures are found to be essentially equivalent for sedentary males and females (metabolic rate ) 50 kcal/h multiplied by m super(2)), whereas the optimal skin temperature for females is found to be 1.2 degree C lower than that for males at a metabolic rate of 150 kcal/h multiplied by m super(2), suggesting an optimal ambient temperature that is 1.2 degree C lower for active females. The evaporative heat loss regressions suggest an additional 1.3 degree C depression of ambient temperature at all metabolic rates for females; however, it is clear from the data that these regressions are inappropriate at low metabolic rates and that the significance of the regressions is poor (R super(2) identical with 0.38 for females and 0.30 for males). A simplified explanation based upon the standard core-periphery heat transfer model and a few morphological differences between men and women is proposed for understanding the observed differences between the sexes. This explanation is found to be consistent with thermoregulatory differences observed in studies of men and women over a large range of thermal conditions. From an HVAC engineer's or building operator's point of view, the observed differences between men and women should be insignificant in office environment; however, these differences could have an impact on design/operation in industrial or recreational facilities.

AN - 744745559; 104762 AB - Changes in four early signal transduction (ST) markers in the calcium-inositol phosphate ST cascade have been correlated with ELF field exposures of the lymphocyte. Following mitogen binding early increases in calcium influx, [Ca super(+2)] sub(i), and [pH] sub(i) induce the early response gene c-MYC and drive the cell into mitogenesis and cell proliferation. The ST cascade provides a plausible biological framework for understanding how ELF effects at the cell membrane can lead to changes in gene expression and cell growth. Here we report preliminary results that calcium influx, [Ca super(+2)] sub(i), [pH] sub(i), and the induction of c-MYC, RNA are elevated in mitogen-activated rat thymic lymphocytes exposed to 60 Hz electric or magnetic fields. Dose response evidence from applied electric field exposures and from magnetic field exposures in which an equivalent electric field is induced indicates that the operative exposure parameter is the electric field.

AN - 17010586; 3850814 AB - This document is a preliminary effort to draw together some of the important simulation models that are available to Reclamation or that have been developed by Reclamation since 1987. This document has also attempted to lay out a framework by which these models might be used both for the purposes for which they were originally intended and to support the analysis of other issues that relate to the hydrology and to salt and water quality management within the San Joaquin Valley. To be successful as components of a larger Decision Support System the models should to be linked together using custom designed interfaces that permit data sharing between models and that are easy to use. Several initiatives are currently underway within Reclamation to develop GIS - based and graphics - based decision support systems to improve the general level of understanding of the models currently in use, to standardize the methodology used in making planning and operations studies and to permit improved data analysis, interpretation and display. The decision support systems should allow greater participation in the planning process, allow the analysis of innovative actions that are currently difficult to study with present models and should lead to better integrated and more comprehensive plans and policy decisions in future years.

The acetone extracts of SRM 1649 and Elizabeth, NJ, samples were 46 and 40% carbon, respectively. When compared to the NJ extract, the SRM extract was enriched in aldehydes and ketones and deficient in carboxylic acids. Significant amounts of organic nitrogen were found in both extracts. Infrared spectra and class tests suggested the presence of nitro compounds, organic nitrates or nitrites, amines, and amides. Fluorescence suggested the presence of polycyclic aromatic species.

The crystals diffract to better than 3.0 angstrom and belong to the orthorhombic space group P2 sub(1)2 sub(1)2 sub(1) with unit cell dimensions a = 308.9 angstrom, b = 208.8 angstrom and c = 116.9 angstrom. There is one molecular complex in the asymmetric unit. Two potentially useful heavy-atom derivatives have been obtained. The self-rotation function of the native Patterson map shows local sevenfold symmetry, consistent with the low-resolution structure obtained by electron microscopic techniques. The unit cell dimensions and crystal symmetry together with the shape and size of the proteasome suggest a packing arrangement of proteasome molecules in the unit cell, with their cylinder axis nearly parallel to the crystallographic a-axis.

In bulk soil samples, Ra concentrations range from 0.6 to 1.3 pCi/g, and variations in Ra, Th, and K appear to be controlled mainly by heterogeneities inherited from the parent granitic rock, which contains abundant dikes and inclusions. U in soil and parent rock is concentrated in primary minerals (mainly zircon and sphene), and in secondary sites that are of greater importance for Rn emanation. The main U-bearing secondary sites are weathered sphene, grain boundary coatings, weathered biotite and plagioclase, as well as dense Fe-rich coatings and a REE-phosphate mineral present in near-vertical fracture zones in saprolite underlying shallow loam. Elevated U in these sites generally correlates with high Ti, Al, Fe, and/or P. JF - Environmental Geology AU - Flexser, S AU - Wollenberg, HA AU - Smith, A R AD - Earth Sci.

The objectives of the study included measurements of optical absorption by suspended material, both windblown dust and aerosol "black" carbon. This latter material is a combustion effluent, prevalent in emissions from poorly controlled burning, with a long atmospheric lifetime and a large cross-section for the absorption of visible radiation. The measurements obtained from the analysis of filter samples indicate that only during periods of active dust production was there a significant contribution of dust to total absorption. At other times, the presence of black carbon from local and regional sources accounted for approximately 90 degree of the total aerosol optical absorption. The conclusions are that fuel combustion may produce a greater optical impact on the atmosphere in less-developed areas of the world than that arising from the effects of desert dust production.

Modelling studies have suggested that most of these nuclei are sulphate aerosols derived from both anthropogenic and natural sources. Here we present evidence that organic aerosols also play a key role in cloud nucleation. We determine the relative contributions of sulphate and organic aerosols to CCN concentrations at a marine site known to be influenced by anthropogenic emissions, and find that organic aerosols account for the major part of both the total aerosol number concentration and the CCN fraction. Thus, in regions that are affected by anthropogenic pollutants, organic aerosols may play at least as important a role as sulphate aerosols in determining the climate effect of clouds.

The discrepancy is often attributed to poor understanding of inherently complex field sites. This paper compares measurements of soil-gas entry made at a full-scale test basement located in natural solid with predictions of a three-dimensional finite difference model. The results corroborate the earlier findings, with the model underpredicting the soil-gas entry rate by a factor of 7.

We measured the Fe L edges of Pyrococcus furiosus rubredoxin, using circularly polarized synchrotron radiation, a split-coil superconducting magnet, low sample temperatures, and fluorescence detection. The observed dichroism effect is strong (30%) and in general agreement with the calculation. The method is element- and oxidation state-specific, and the data can be interpreted by established theoretical procedures. Soft x-ray magnetic circular dichroism demonstrates enormous potential as a probe for studying paramagnetic systems in biology, chemistry, and material science.

This information can, therefore, be of great value in planning the Exploratory Studies Facility (ESF) testing in underground drifts at Yucca Mountain. In this paper, we compare the geohydrologic characteristics of tuff units of these two sites and summarize the hydrochemical data indicating the presence of nearly meteoric water in Rainier Mesa tunnels. A simple analytic model is used to evaluate the possibility of propagating transient pulses of water along fractures or faults through the Paintbrush nonwelded tuff unit to reach the tunnel beds below. The results suggest that fast flow could occur without significant mixing between meteoric fracture water and matrix pore water. The implications of these findings on planning for the ESF Calico Hills study at Yucca Mountain are discussed.

AN - 16697778; 2978525 AB - Prediction of a positive result in rodent carcinogenesis bioassays using two instead of four sex-species groups is examined for the subset of chemicals in the Carcinogenic Potency Database that have been tested in four sex-species groups and are positive in at least one. Under the conditions of these bioassays, a very high proportion of rodent carcinogens that are identified as positive by tests in four groups is also identified by results from one sex of each species (86-92%). Additionally, chemicals that are classified as "two-species carcinogens" or "multiple-site carcinogens" on the basis of results from four sex-species groups are also identified as two-species or multiple-site carcinogens on the basis of two sex-species groups. Carcinogenic potency (TD50) values for the most potent target site are similar when based on results from two compared to four sex-species groups. Eighty-five percent of the potency values are within a factor of 2 of those obtained from tests in 4 sex-species groups, 94% are within a factor of 4, and 98% are within a factor of 10.

AN - 16696577; 2978523 AB - The purpose of this report is determine the impact of charged particle irradiation at Lawrence Berkeley Laboratory (LBL) in treating patients with sacral chordomas. Overall survival, local control, complications, and predictive parameters are analyzed. One previously irradiated patient required colostomy, one patient had delayed wound healing following a negative post-radiation biopsy, and one patient developed a second malignancy. There were no genitourinary complications. Our experience indicates that post-operative charged particle irradiation of sacral chordomas appears to result in reasonable local control and survival with acceptable risk, and that additional evaluation on the use of heavy charged particles is warranted.

Liver-derived HSCs from nonthalassemic syngeneic murine fetal donors were transplanted into nonirradiated neonatal beta -thalassemic recipients. Significant erythrocyte chimerism (9-27%) was demonstrated in the majority of recipients at 1 month and remained stable or increased (up to 55%) during long-term follow-up in almost all cases. Chimeras had improved phenotypes, as evidenced by decreased reticulocyte counts, increased mean erythrocyte deformability, and decreased iron deposits in comparison to controls. To investigate whether the high degree of peripheral blood chimerism was predominantly a feature of erythroid elements or was a general feature of all hematopoietic elements, chimeras were created using donor HSCs "tagged" with a DNA transgene. Whereas donor hemoglobin comprised >30% of total hemoglobin, nucleated tagged nonerythroid donor cells comprised <1% of peripheral blood elements. Explanations for the observed selective increase in erythroid chimerism include longer survival of normal donor red cells compared to that of thalassemic red cells and the effective maturation of the donor erythroid elements in the bone marrow in chimeric animals. The latter explanation bears consideration because it is consistent with the process of ineffective erythropoiesis, well documented to occur in thalassemia, in which the majority of thalassemic erythroid cells are destroyed during erythropoiesis prior to release from the bone marrow. The data demonstrate the potential for significant erythroid chimerism and suggest that fetal HSC transplantation may play a significant role in future treatment.

The NEPA process is intended to help officials of the federal government make decisions that are based on an understanding of environmental consequences, and take actions that protect, restore, and enhance the environment. The California Environmental Quality Act of 1970 (CEQA) is similar to NEPA. The California legislature established CEQA to inform both state and local governmental decision-makers and the public about potential significant environmental effects of proposed activities, to identify ways to avoid or reduce environmental impacts, and to disclose to the public the reasons why a project is approved if significant environmental effects are involved. Lawrence Berkeley Laboratory (LBL), complies with the provisions of both NEPA and CEQA. This document defines the responsibilities and authorities for NEPA/CEQA compliance at LBL.

AN - 16655025; 3035033 AB - High-density lipoprotein (HDL) contains two major proteins, apolipoprotein A-I (apoA-I) and apolipoprotein A-II (apoA-II), comprising about 70% and 20% of the total HDL protein mass, respectively. HDL exists in human plasma in two main forms, one containing apoA-I with apoA-II (AI/AII-HDL) and another containing apoA-I without apoA-II (AI-HDL). A strong inverse relationship exists between total plasma HDL concentration and atherosclerosis, but the results of studies examining the relationship between AI-HDL and AI/AII-HDL and atherosclerosis have been conflicting. To determine whether these two HDL populations have different effects on atherogenesis, human apoA-I (AI) and human apoA-I and apoA-II (AI/AII) transgenic mice were produced in an atherosclerosis-susceptible strain. Following an atherogenic diet, despite similar total cholesterol and HDL cholesterol concentrations, the area of atherogenic lesions in the AI/AII mice was 15-fold greater than in the AI animals. The studies show that the protein composition of HDL significantly affects its role in atherogenesis and that AI-HDL is more anti-atherogenic than AI/AII-HDL.

Structural comparison to the cross-linked mutant forms and conformational changes upon ligand binding. AN - 16651310; 3000548 AB - The three-dimensional structures of the ligand-binding domain of the wild-type Salmonella typhimurium aspartate receptor have been determined in the absence (apo) and presence of bound aspartate (complex) and compared to a cross-linked mutant containing a cysteine at position 36 which does not change signaling behavior of the intact receptor. As in the case of the cross-linked mutant receptor, the non-cross-linked ligand-binding domain is dimeric and is composed of 4- alpha -helical bundle monomer subunits related by a crystallographic 2-fold axis in the unbound form and by a non-crystallographic axis is the aspartate-bound form. A comparative study between the non-cross-linked and cross-linked structures has led to the following observations: 1) The long N-terminal helices of the individual subunits in the cross-linked structures are bent toward each other to accommodate the disulfide bond. 2) The rest of the subunit conformation is very similar to that of the wild-type. 3) The intersubunit angle of the cross-linked apo structure is large by about 13 degrees when compared to the wild-type apo structure. 4) The nature and magnitude of the aspartate-induced conformational changes in the non-cross-linked wild-type structures are very similar to those of the cross-linked structures.

AN - 16651216; 3035370 AB - Radon entry into a Florida house whose concrete slab is supported by a permeable concrete-block stem wall and a concrete footer is modeled. The slab rests on backfill material; the same material is used to fill the footer trench. A region of undisturbed soil is assumed to extend 10 m beyond and below the footer. The soil is assumed homogeneous and isotropic except for certain simulations in which soil layers of high permeability or radium content are introduced. Depressurization of the house induces a pressure field in the soil and backfill. The Laplace equation, resulting from Darcy's law and the continuity equation, is solved using a steady-state finite-difference model to determine this field. The mass-transport equation is then solved to obtain the diffusive and advective radon entry rates through the slab; the permeable stem wall; gaps at the intersections of the slab, stem wall, and footer; and gaps in the slab.

AN - 16645261; 53170 AB - An x-ray microscopy resource center for biological x-ray imaging will be built at the Advanced Light Source (ALS) in Berkeley, California. The unique high brightness of the ALS allows short exposure times and high image quality. Two microscopes, an x-ray microscope (XM) and a scanning x-ray microscope (SXM) are planned. These microscopes serve complementary needs. The XM gives images in parallel at comparable short exposure times, and the SXM is optimized for low radiation doses applied to the sample. The microscopes extend visible light microscopy toward significantly higher resolution and permit images of objects in an aqueous medium. High resolution is accomplished by ates. Design considerations to serve the needs of biological x-ray microscopy are given. Also the preliminary design of the microscopes is presented. Multiple wavelength and multiple view images will provide elemental contrast and some degree of 3-D information. JF - INT SOC FOR OPTICAL ENGINEERING, BELLINGHAM, WA (USA).

AN - 16636317; 2985411 AB - A comparison of target organs for mutagens and non-mutagens is presented for 351 rodent carcinogens in the Carcinogenic Potency Database (CPDB) with mutagenicity evaluations in Salmonella . Results are consistent with the hypotheses that in high-dose rodent tests mitogenesis is important in the carcinogenic response for mutagens and non-mutagens alike, and that mutagens have a multiplicative interaction for carcinogenicity because they can both damage DNA directly and cause cell division at high doses. These hypotheses would lead one to expect several results that are found in the analysis: First, a high proportion of both mutagens and non-mutagens induce tumors in rodent bioassays at the MTD. Second, mutagens compared to non-mutagens are: (a) more likely to be carcinogenic; (b) more likely to induce tumors at multiple target sites; and (c) more likely to be carcinogenic in two species. Among carcinogens that induce tumors at multiple sites in both rats and mice, 81% are mutagens; in comparison, among carcinogens that are positive at only a single target site in one species and are negative in the other, 42% are mutagens.

AN - 16622440; 53168 AB - X-ray microscopy has the potential to become a powerful tool for the study of biological samples, allowing the imaging of intact cells and subcellular organelles in an aqueous environment at resolutions previously achievable only by electron microscopy. The ability to examine a relatively thick sample raises the issue of superposition of objects from multiple planes within the sample, making difficult the interpretation of conventional, orthogonally projected images. This paper describes our early attempts at developing three-dimensional methods for x-ray microimaging: the first to use x-ray optics, and to our knowledge, the first demonstrating sub-visible resolutions and natural contrast. These studies were performed using the scanning transmission x-ray microscope (STXM) at the National Synchrotron Light Source, Brookhaven National Laboratory.

AN - 16621058; 53163 AB - Using quantitative scanning transmission x-ray microscopy, zymogen granules isolated from pancreatic acinar cells were observed suspended in aqueous medium at 50 nm resolution. From 3.64 nm x-ray absorption data, the protein content and rate of protein efflux from individual granules were determined. This was accomplished with a specially designed silicon nitride based wet-cell that allowed continuous perfusion and monitoring of individual granules in a variety of different aqueous environments. Granules suspended in 300 mM sucrose, 5 mM phosphate buffer (pH 6.0) were observed to continuously decrease in size and protein content over a period of several hours. Sudden lysis of the granules was not observed. From the flux data, the apparent protein permeability coefficients for individual granules were determined to range from 1 - 10 x 10 super(-10) cm/sec with an average of 4.78 plus or minus 3.0 x 10 super(-10) cm/sec. We believe this is the first quantitative population profile determined for a subcellular organelle developed from measurements of individual members of the population.

For the dithionite-reduced Azotobacter vinelandii Mo-Fe protein, the dominant EXAFS Fourier transform peaks are assigned to Fe-S and Fe-Fe interactions at similar to 2.32 and 2.64 angstrom, as expected for Fe-S clusters. An additional Fe-Mo component at 2.73 angstrom is required to completely fit the EXAFS in the 1-3-angstrom region. In the 3-5-angstrom region, a 3.8-angstrom Fe-Fe component is identified, with an amplitude corresponding to almost one long Fe-Fe interaction, averaged over all of the iron in the sample. Features that can be explained as Fe-S and Fe-Fe interactions at 4.3 and 4.7 angstrom are also observed. A similar pattern of Fe interactions is observed for the reduced A. vinelandii V-Fe protein, except that the short Fe-Mo interaction is no longer required. In both Mo-Fe and V-Fe proteins, the first coordination sphere Fe-S distances contract slightly upon thionine oxidation. The long-range Fe-S and Fe-Fe interactions are very close (within 0.1 angstrom) to corresponding distances in Fe sub(6)S sub(6) prismane clusters. If the amplitudes are adjusted by assuming that only 14 of 30 nitrogenase irons participate in the M center, then they are consistent with recently proposed crystallographic models.

This supplement includes results of 412 long-term, chronic experiments of 147 test compounds and reports the same information about each experiment in the same plot format as the earlier papers: the species and strain of test animal, the route and duration of compound administration, dose level and other aspects of experimental protocol, histopathology and tumor incidence, TD sub(50) (carcinogenic potency) and its statistical significance, dose response, author's opinion about carcinogenicity, and literature citation. We refer the reader to the 1984 publications (1,5,6) for a guide to the plot of the database, a complete description of the numerical index of carcinogenic potency, and a discussion of the sources of data, the rationale for the inclusion of particular experiments and particular target sites, and the conventions adopted in summarizing the literature.

AN - 16498353; 38992 AB - The author argues that it is possible to include decision making operations into reconstruction algorithms. He attempts to demonstrate that it is possible to develop algorithms producing various attributes of reconstructed images or other images related to them directly from the projection data. The concepts are presented through examples, which are conceptually similar. It is assumed that a vector of projection data is available to answer questions pertaining to the unknown underlying density distribution that generated the data, which is estimated in tomography. The questions are posed in terms of a subset of pixels called a region of interest (ROI) or several ROIs. Hypothesis testing is considered in relation to the ROIs. The essence of the approach is that instead of measuring the average value in a ROI in reconstructed images, the author proposes to determine whether the raw data supports or is consistent with the assumption or stated hypothesis.

AN - 16496979; 38990 AB - The mathematical representation of images by visual response functions (VRFs) is considered. The focus is on the use of a natural representation in terms of VRFs based on the pioneering work of J. J. Koenderink at the University of Utrecht on multiscale vision reception fields. Work is described in published literature, as well as new work that can be useful for the representation of anatomical prior knowledge to aid in the reconstruction of tomographic data. The aim is to show how some specific characteristics or features of an image can be found by a machine observer.

AN - 16490257; 2943714 AB - We present the nucleotide and deduced amino acid sequences of four contiguous bacteriochlorophyll synthesis genes from Rhodobacter capsulatus . Three of these genes code for enzymes which catalyze reactions common to the chlorophyll synthesis pathway and therefore are likely to be found in plants and cyanobacteria as well. The pigments accumulated in strains with physically mapped transposon insertion mutations are analyzed by absorbance and fluorescence spectroscopy, allowing us to assign the genes as bchF, bchN, bchB, and bchH, in that order. bchF encodes a bacteriochlorophyll a-specific enzyme that adds water across the 2-vinyl group. The other three genes are required for portions of the pathway that are shared with chlorophyll synthesis, and they were expected to be common to both pathways. bchN and bchB are required for protochlorophyllide reduction in the dark (along with bchL), a reaction that has been observed in all major groups of photosynthesis organisms except angiosperms, where only the light-dependent reaction has been clearly established. The purple bacterial and plant enzymes show 35% identity between the amino acids coded by bchN and chlN (gidA) and 49% identity between the amino acids coded by bchL and chlL (frxC). Furthermore, bchB is 33% identical to ORF513 from the Marchantia polymorpha chloroplast. We present arguments in favor of the probable role of ORF513 (chlB) in protochlorophyllide reduction in the dark. The further similarities of all three subunits of protochlorophyllide reductase and the three subunits of chlorin reductase in bacteriochlorophyll synthesis suggest that the two reductase systems are derived from a common ancestor.

AN - 16463664; 2928406 AB - We have compared the effects of a number of different oligonucleotides on the growth and morphology of normal finite life span and immortality transformed human mammary epithelial cells. The oligonucleotide sequences chosen initially for study were based on that of the NB-1 gene, which encodes a calmodulin-like protein of unknown function. We found that certain thioated oligonucleotides 15-20 residues in length altered the morphology and decreased the growth rate of the normal cells in a concentration-dependent manner. These effects were rapid, occurring within 24-48 h of oligonucleotide addition. The effects, which occurred without an accompanying detectable decrease in the levels of NB-1 mRNA or protein, were most pronounced in the normal epithelial cells, less apparent in the immortalized epithelial cells, and unobserved in normal breast fibroblasts. Identical sequences having mixed phosphodiester and phosphorothioate backbones, or phosphodiester backbones alone, had little or no effect on normal epithelial cell morphology or growth. Two out of seven additional thioated oligonucleotides which were not complementary to NB-1 mRNA, also affected normal epithelial cell morphology and growth when used at similar concentrations (10 mu M). Taken together, the observed effects on normal epithelial cells indicate that certain thioated oligonucleotides may have pharmacological consequences that do not depend on strict complementarity of their sequences to known mRNAs.

AN - 16380427; 2862885 AB - Rate constants for bimolecular reactions between ozone and a group of alkylpyridines were estimated by application of a pseudo-first-order technique involving time-course monitoring of reactor contents. The method used was a modification of an existing protocol for evaluation of gas-phase reaction kinetics. Reaction progress was followed spectroscopically. The method was found to be inadequate for accurate determination of kinetic parameters due to absorptive interferences; however, it was sufficient for defining lower limits of reaction rate constants. Tropospheric reactions of alkylpyridines with ozone were found to be extremely slow, with atmospheric lifetimes of the order of years.

The tool for our investigation is an integral finite difference numerical code which can solve for both diffusive and advective flux of radon in the soil gas which is treated as a slightly compressible fluid. Two different boundary conditions at the house basement are considered: (1) a dirt floor basement so that diffusion is equally or more important than advective transport, and (2) an "impermeable" cement basement except for a 1-cm-wide crack near the perimeter of the basement floor; in which case, advective transport of radon flux dominates. Two frequencies of barometric pressure fluctuation with representative values of amplitudes, based on a Fourier decomposition of barometric pressure data, were chosen in this study: one with a short period of 0.5 hour with pressure amplitude of 50 Pa, the other a diurnal variation with a period of 24 hours with the typical pressure amplitude of 250 Pa. For a homogeneous soil medium with soil permeability to air between 10 (super -13) and 10 (super -10) m (super 2) , we predict that the barometric fluctuations increase the radon entry into the basement by up to 120% of the steady radon inflow into the basement owing to a steady depressurization of 5 Pa. If soil permeability heterogeneity is present, such as the presence of a thin layer of higher permeability aggregate immediately below the basement floor, radon flux due to atmospheric pumping is further increased. Effects of pressure pumping on radon entry are also compared to diffusion-only transport when the steady depressurization is absent. It is found that contribution to radon entry is significant for the basement crack configuration. In particular, for pressure pumping at 0.5-hour period and for a homogeneous medium of permeability of 10 (super -10) m (super 2) , the radon entry is a factor of 10 larger than that predicted by the diffusion-only transport. This may help to explain indoor radon concentrations during times of low steady state driving force. Extending beyond radon transport, the results of this case study establish the importance of transient advective transport resulting from atmospheric pressure variation.

In particular, the study uses detailed numerical models of evaporative coolers linked with the DOE-2 building energy simulation program to study the issues of indoor comfort, energy and peak demand savings with and without supplemental air-conditioning and consumptive water use. In addition, limited surveys are used to assess the current market availability of evaporative cooling in California, typical contractor practices and costs, and general acceptance of the technology among engineers, contractors, and manufacturers. The results show that evaporative coolers can provide significant energy and peak demand savings in California residences, but the impact of the increased indoor humidity on human comfort remains an unanswered question that requires further research and clarification. Evaluated against ASHRAE comfort standards developed primarily for air-conditioning both direct and two-stage evaporative coolers would not maintain comfort at peak cooling conditions due to excessive humidity. However, using bioclimatic charts that place human comfort at the 80% relative humidity line, the study suggests that direct evaporative coolers will work in mild coastal climates, while two-stage models should provide adequate comfort in Title 24 houses throughout California, except in the Imperial Valley. The study also shows that evaporative coolers will increase household water consumption by less than 6% on an annual basis, and as much as 23% during peak cooling months, and that the increases in water cost are minimal compared to the electricity savings. Lastly, a survey of engineers and contractors revealed generally positive experiences with evaporative coolers, with operational cost savings, improved comfort, unproved air quality as the primary benefits in their use.

The mass transfer processes are governed by reactive phase compositions, surface areas, water-rock ratios, reaction rates, and fluid residence times. Experimental dissolution of the vitric phase of the tuff was congruent with respect to Cl in the solid and produced reaction rates which obeyed a general Arrhenius release rate of 250-300 degrees C. The (super 18) O differences between reacted and unreacted rock and fluids, and mass-balance calculations involving Cl in the glass phase, produced comparable water-rock ratios of unity, confirming the importance of irreversible reaction of the vitric tuff. A fluid residence time of approx 2 x 10 (super 3) years is < 0.2% of the age of the hydrothermal system and indicates a geochemically and isotopically open system. Mass transfer calculations generally replicated observed reservoir pH, PCO (sub 2) and PO (sub 2) conditions, cation concentrations, and the secondary mineral assemblage at 250-300 degrees C. The only extraneous component required to maintain observed calcite saturation and high PCO (sub 2) was C, presumably derived from underlying Palaeozoic limestones. Phase rule constraints indicate that Cl was the only incompatible aqueous component not controlled by mineral equilibrium. Concentrations of Cl in the reservoir directly reflect mass transport rates.

To study this problem, a recently developed semianalytical solution for two-phase flow of water and heat in a porous medium has been extended to include an air component and to incorporate several physical effects that broaden its range of applicability. The problem considered is the placement of a constant-strength linear heat source in an infinite homogeneous medium with uniform initial conditions. Under these conditions the governing partial differential equations in radial distance r and time t reduce to ordinary differential equations through the introduction of a similarity variable eta = r/t (super 1/2) . The resulting equations are coupled and nonlinear, necessitating a numerical integration. The similarity solution developed here is used to investigate various physical phenomena related to partially saturated flow in low-permeability rock, such as vapor pressure lowering, pore level phase change effects, and an effective continuum representation of fractured/porous media. Application to several illustrative problems arising in the context of high-level nuclear waste disposal at Yucca Mountain, Nevada, indicates that fluid flow, phase changes, and latent heat transfer may have a significant impact on conditions at the repository.

The attenuating effects are introduced by substituting the real elastic parameters for perfectly elastic media by complex frequency dependent elastic parameters with small imaginary parts. The imaginary parts are formally considered to be of the order of omega (super -1) for omega --> infinity. Under this assumption, it is possible to work with real rays, only the eikonal is complex. The approximate computations based on this algorithm are only a few percent slower than those for perfectly elastic anisotropic media. The range of applicability of the weak attenuation concept is investigated by comparison of ray computations with results of the reflectivity method for an isotropic, constant gradient model. The study indicates that the region of applicability of the weak attenuation concept may be broader than expected. The combined effects of anisotropy and attenuation on the propagation of seismic waves in a three-dimensional model of the uppermost crust with an anisotropic attenuating layer are then studied. The anisotropy as well as the attenuation are supposed to be caused by aligned partially liquid-filled cracks. Hudson's formulas to compute complex effective elastic parameters are used. Frequency responses and VSP synthetic seismograms for different degrees of viscosity of the liquid, and, thus, different degree of attenuation, show the effects of attenuation on the propagating waves. Nine-component VSP vector wavefields are computed for two different source-borehole directions along the strike of the cracks and 45 degrees off the strike of the cracks. The seismograms for the attenuating model are compared with seismograms for the corresponding perfectly elastic model.

This difficult task requires predictions concerning progress in available technology over the 15-year period of the HGP, and continuous reassessment of feasible targets. The priority is to obtain the most useful sequence information first - strategies reviewed below for achieving this involve targeting coding and control regions, analysis and manipulation of genomes of model organisms, and the parallel analysis of homologous genomic regions of both human and model organisms.

We studied reactions of these compounds in solutions with other constituents of the waste streams and suspended clay at concentrations and temperatures higher than expected in natural situations, i.e. at 200 degree C and 250 degree C. Under these conditions, the predominant reaction was the demethylation of cresol to form phenol. This reaction was catalyzed strongly by clay. We were able to quantify phenol production. Other important reactions were a variety of condensation reactions in which two cresol molecules fuse. We found evidence of the intermolecular migration of methyl groups from the molecular weights of some of these condensation reactions. By digesting a sample of reacted clay with hydrofluoric acid we determined that under these conditions phenol and cresol did not bind appreciably to clay but that the condensation products did.

The unique aspect of the conjunctive use model is its coupling of a surface water delivery operations model with a regional groundwater model. A salinity model has been added to utilize surface water model output and allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. The results of scenario runs, performed to data, using the SANTUCM model show table lowering and consequent drainage reduction can be achieved through a combination of source control, land retirement and regional groundwater pumping. The model also shows that water transfers within the existing distribution system are technically feasible and might allow additional releases to be made from Friant Dam for water quality maintenance in the San Joaquin River. However, upstream of Mendota Pool, considerable stream losses to the aquifer are anticipated, amounting to as much as 70% of in-stream flow.

Based on these data, a mass balance model for selenium has been developed and employed to evaluate the rate of leaching, remobilization and volatilization that has occurred since the Reservoir was dried out in 1987. Results from a series of calibration runs were then extrapolated 25 years in the future to forecast the evolution and redistribution of selenium within the soil profile. Projected water-extractable selenium concentrations within the 0.15 to 1 m depth interval were then used to drive a food-chain based risk-assessment model described in a separate report (CH2M Hill, 1992). Inventories of water-extractable selenium in the root zone increased in 4 of the 5 scenarios investigated. However, predicted values for the average concentration of water-extractable selenium in the root zone fall within the range of values observed at Kesterson today. Consequences of these projected increases on wildlife residing in and around Kesterson are addressed in CH2M Hill (1992).

(1960), double-porosity models have been widely used for simulating flow in fractured reservoirs, such as geothermal reservoirs. In a dual-porosity system, the matrix blocks provide most of the storage of the reservoir, whereas the fractures provide the global transmissivity. Initially, most work on dual-porosity models emphasized the development of analytical solutions to idealized reservoir problems. Increasingly, the dual-porosity approach is being implemented by numerical reservoir simulators. Accurate numerical simulation of a dual-porosity problem often requires a prohibitively large number of computational cells in order to resolve the transient pressure gradients in the matrix blocks. We discuss a new dual-porosity model that utilizes a nonlinear differential equation to approximate the fracture/matrix interactions, When implemented into a numerical simulator, it eliminates the need to discretize the matrix blocks, and thereby allows more efficient simulation of reservoir problems.

LTMQ combines a MultiQuadrics (MQ) approximation scheme with a Laplace transform formulation. The use of MQ in the spatial approximations allows the accurate description of problems in complex porous media with a very limited number of nodes. The Laplace transform formulation eliminates the need for time discretization, thus allowing an unlimited time step size without any loss of accuracy. LTMQ is tested against results from three test problems of groundwater flow obtained from a standard Finite Difference (FD) model, as well as from analytical solutions. An excellent agreement between the LTMQ and the analytical and FD solutions is observed, while significant reductions in computer execution times may be achieved.

AN - 16491828; 2944829 AB - Prediction of human cancer risk from the results of rodent bioassays requires two types of extrapolation: A qualitative extrapolation from short-lived rodent species to long-lived humans, and a quantitative extrapolation from near-toxic doses in the bioassay to low-level human exposures. Experimental evidence on the accuracy of prediction between closely related species tested under similar experimental conditions (rats, mice, and hamsters) indicates that: (1) if a chemical is positive in one species, it will be positive in the second species about 75% of the time; however, since about 50% of test chemicals are positive in each species, by chance alone one would expect a predictive value between species of about 50%. (2) If a chemical induces tumors in a particular target organ in one species, it will induce tumors in the same organ in the second species about 50% of the time.

AN - 16446134; 2912626 AB - Applications of ecological toxicity testing to hazardous waste management have increased dramatically over the last few years, resulting in a greater awareness of the need for improved biomonitoring techniques. The authors' lab is developing advanced techniques to assess the genotoxic effects of environmental contamination on ecosystems. We have developed a novel mutagenesis assay using the nematode Caenorhabditis elegans , which is potentially applicable for multimedia studies in soil, sediment, and water. They are also conducting validation studies of a previously developed anaphase aberration test that utilizes sea urchin embryos. Other related efforts include field validation studies of the new tests, evaluation of their potential ecological relevance, and analysis of their sensitivity relative to that of existing toxicity tests that assess only lethal effects, rather than genetic damage.

AN - 16445833; 2911239 AB - Most researchers who have studied effects of low pH on amphibians that breed in temporary ponds measured direct lethal effects on single species. We summarize here results of a study conducted over 4 years in central Pennsylvania that illustrate the potential ecological importance of direct and indirect effects of low pH at lethal and sublethal levels. We argue for use of a multilevel approach (field sampling and experimentation in the laboratory, simulated ponds, and natural ponds) to study such effects on embryonic and larval amphibians of temporary ponds. A greater proportion of our study ponds was lower in pH than any reported previously in North America. Ponds were soft and often had high (Al sub(total)). Median seasonal pHs of 9 ponds were negatively associated with total amounts of rainfall over 4 years, but were not associated with H super(+) deposition during that same period. The pHs of many declined as total rainfall increased. Embryonic mortality of the salamander Ambystoma jeffersonianum) was high in ponds below pH 4.5.

AN - 16443885; 31839 AB - In this paper we examine the possibility of using pure geometrical information from a prior image to assist in the reconstruction of tomographic data sets with lower number of counts. The situation can arise in dynamic studies, for example, in which the sum image from a number of time frames is available, defining desired regions-of-interest (ROIs) with good accuracy, and the time evolution of uptake in those ROIs needs to be obtained from the low count individual data sets. The prior information must be purely geometrical in such a case, so that the activity in the ROIs of the prior does not influence the estimated uptake from the individual time frames. It is also desired that the prior does not impose any other conditions on the reconstructions, i.e., no smoothness or deviation from a known set of values is desired. We attack this problem in the framework of vision response functions (VRFs), based on the work done by J. J. Koenderink in Utrecht. We show that there are assemblies of VRFs that can be presented in a form that is invariant with respect to rotations and translations and that some functions of those invariants can convey the desired geometric prior information independent of the level of activity in the ROIs, except at very low levels. Preliminary results based on a one-dimensional reconstruction problem are presented. Using the zero crossings of the Gaussian derivative form of the Laplacian of a prior image at different scales, a variant of the EM algorithm has been found that allows the reconstruction of low count data sets with those priors. At this time, this involves using a modified conjugate gradient (CG) maximization method for the M-step of the algorithm. The results show that the distorted shapes of reconstructions of data sets with low counts are effectively corrected by the method, although many questions exist at this time about basic and computational issues.

AN - 16398856; 2881032 AB - We propose measuring chlorinated hydrocarbon emissions from hazardous waste incinerators by fragmenting molecules in the exhaust stream with high powered UV laser light, then measuring the subsequent concentration of the CCl fragment via laser induced fluorescence. We have shown that one of the chlorinated hydrocarbons, C sub(2)H sub(5)Cl, can be efficiently fragmented by 193 nm ArF excimer laser under the necessary conditions of atmospheric pressure and elevated temperatures, and in mixtures with air, H sub(2)O, and CO sub(2). When a delayed pulse of light at 271.4 nm is added to the 193 nm pulse, fluorescence from CCl generated by the fragmentation process can be detected. The CCl fluorescence can be easily distinguished from O sub(2) emission excited by the 193 nm laser due to the time interval between the different colored laser pulses. The level of CCl fluorescence is strongly dependent on the C sub(2)H sub(5)Cl concentration for the range of concentrations measured, 3 to 300 ppm. Conversely, CCl fluorescence could not be detected following the fragmentation of mixtures containing 0.15% HCl and 0.2% C sub(2)H sub(4).

AN - 16391138; 2882511 AB - Two approaches were taken to estimate evaporation of water from the surface of a salt-encrusted and Se contaminated soil in a playalike environment at Kesterson Reservoir, California. Direct evaporation flux measurements were made using a lysimetric (gravimetric) approach and revealed a seasonal dependence of bare soil evaporation rates, which ranged from 0.1 to 1.5 mm/d. The low range is suggestive of a vapor-flux control of bare soil evaporation due to the presence of a salt crust. Temporal changes in chloride concentrations and soil moisture content were used in a quantitative assessment of a mean seasonal evaporative flux.

AN - 16389569; 2880667 AB - After failing to take any significant action for years - in part because of the Reagan administration's distaste for environmental regulation - in the mid-1980s EPA launched a wide-ranging campaign to convince everyone who was at even relatively low risk from radon to take remedial action. In its zeal to spur millions of homeowners to act, EPA directed an alarmist - and often misleading or inaccurate - public information effort. The practical outcome has been a confused public, a frustrated EPA, and a large number of households that are still exposed to a very significant cancer risk. No more time should be wasted before putting government radon policy on a practical and effective course. What is needed is a program that provides sound information to the public, focuses first on the homes with genuinely high concentrations, and undertakes a careful evaluation of average exposures, the need to reduce them, and practical measures to do so.

In this paper, we survey attitudes and policy responses among the nations of the world. Public opinion surveys are consistent in showing that considerable sensitivity to environmental issues exists virtually everywhere. JF - ENERGY.

AN - 16355346; 11834 AB - A field study of thermal comfort was conducted in Bangkok, Thailand, in which over 1100 office workers responded to a questionnaire while simultaneous physical measurements were taken. In this study we explore whether there is justification for adopting a comfort standard that differs from those developed for office workers accustomed to more temperate climates. Both air-conditioned and naturally ventilated offices were surveyed. Participants cast votes on standard subjective thermal rating scales and these were correlated with temperature indices that variously account for the thermal impacts of humidity, radiant temperature, air velocity, and clothing levels. Following the criteria used in developing a widely adopted thermal comfort standard, it was found that the upper temperature bound for a Thai comfort standard, instead of being the currently accepted level of 26.1 degree C, should be as high as 31 degree C for office workers accustomed to naturally ventilated spaces, and as high as 28 degree C for those accustomed to air-conditioning. Comparing the responses from the naturally ventilated buildings with both those from the air-conditioned buildings and from studies conducted in the temperate regions provides convincing evidence of acclimatization. These and other findings of this study suggest that interior spaces in Thailand can be cooled to as far lesser degree without sacrificing comfort.

AN - 16342928; 2848653 AB - The human diet contains an enormous background of natural chemicals, such as plant pesticides and the products of cooking, that have not been a focus of carcinogenicity testing. A comparison of possible hazards of 80 daily exposures to rodent carcinogens from a variety of sources is presented, using an index (HERP) that relates human exposure to carcinogenic potency in rodents. A similar ordering would be expected with the use of standard risk assessment methodology for the same human exposure values. Results indicate that, when viewed against the large background of naturally occurring carcinogens in typical portions of common foods, the residues of synthetic pesticides or environmental pollutants rank low. A similar result is obtained in a separate comparison of 32 average daily exposures to natural pesticides and synthetic pesticide residues in the diet.

AN - 16341914; 2852012 AB - We describe a model system to measure the rate of supercoiling by transcription and to estimate the rates of topoisomerase turnover in Escherichia coli . Transcription in a strain lacking topoisomerase I can lead to optimal supercoiling, wherein nearly one positive and one negative superturn are produced for each 10.4 base pairs transcribed. This rapid efficient supercoiling is observed during transcription of membrane-associated gene products, encoded by tet (the gene for tetracycline resistance) and phoA (the gene for E. coli alkaline phosphatase), when the genes are oppositely oriented. Replacement of tet by cat, the gene from Tn9 encoding resistance to chloramphenicol, whose gene product is soluble in the cytosol, reduces the efficiency of supercoiling by RNA polymerase. In a wild-type topoisomerase background, both gyrase and topoisomerase I are kinetically competent to relieve superturns produced by transcription. The results suggest that the level of DNA supercoiling in vivo is probably determined by topoisomerase activity, not by transcription.

AN - 16300894; 2818716 AB - Erwinia herbicola , a nonphotosynthetic bacterium, is yellow colored due to the accumulation of unusually polar carotenoids, primarily mono- and diglucosides of zeaxanthin. We have cloned and expressed the gene for the enzyme that catalyzes the glucosylation of zeaxanthin. The enzyme has an apparent molecular mass of 45 kDa on an SDS/polyacrylamide gel, which is consistent with its calculated molecular mass. In vitro enzymatic activity was demonstrated using UDP-( super(14)C)glucose and zeaxanthin as substrates. The product zeaxanthin diglucoside and its intermediate monoglucoside were identified by thin layer chromatography. The optimum pH and temperature range of the enzyme are 7.0-7.5 and 32-37 degree C, respectively. A hydropathy plot indicates no apparent membrane-spanning regions, and biochemical experiments suggest that the enzyme is weakly membrane-associated. The amino acid sequence derived from the zeaxanthin glycosyltransferase gene shows a small region of high similarity with other glucuronosyl-and glucosyltransferases that use either UDP-activated glucuronic acid or a sugar as one of their substrates.

AN - 16244066; 2769702 AB - The reaction between NH sub(3) and SO sub(2) in thin water films was studied with a focus on the formation of sulfate. The reactions were conducted at 5 and 60% relative humidities or partial pressure of water vapor and at 0.04, 0.16 or 0.20 atm O sub(2) for temperatures between 20 and 50 degree C using a flow reactor and static flask reactors. In the presence of water vapor, the oxidation of SO sub(2) to sulfate was observed only when NH sub(3) was present. The product was primarily (NH sub(4)) sub(2)SO sub(4). Conversion of as much as 81% of the SO sub(2) to sulfate was observed after 10 min of reaction when the initial concentrations of SO sub(2) and NH sub(3) were 1 ppm and the relative humidity was 60%. Conversion was only 1-3% when NH sub(3) and/or water vapor were absent from the system. JF - Atmospheric Environment, Part A AU - Benner, W H AU - Ogorevc, B AU - Novakov, T AD - Appl. Sci.

AN - 16238230; 2767096 AB - The RAD54 gene of Saccharomyces cerevisiae is involved in the recombinational repair of DNA damage. The predicted amino acid sequence of the RAD54 protein shows significant homologies with the yeast SNF2 protein, which is required for the transcriptional activation of a number of diversely regulated genes. These proteins are 31% identical in a 492-amino acid region that includes presumed nucleotide and Mg super(2+) binding sites. We noted previously that the SNF2 protein also shares homology with a partial open reading frame (ORF) that was reported with the sequence of an adjacent gene. This ORF also shares homology with the RAD54 protein. This gene has been identified as RAD16, a gene involved in the excision repair of DNA damage. Analysis of the rad16 deletion mutations indicates that RAD16 encodes a non-essential function and is not absolutely required for excision repair. Outside the region of homology to RAD54 and SNF2, the predicted RAD16 protein contains a novel cysteine-rich motif that may bind zinc and that has been found recently in eleven other proteins, including the yeast RAD18 protein.

AN - 16238164; 2766454 AB - The most effective ways to reduce CO sub(2) emissions are to improve the energy efficiency of each economic sector and to reduce the cutting of tropical and temperate forests around the world. These options, however, may not fully reach their technical and economic potential due to various political and socioeconomic barriers. Other more innovative and less well developed mitigation measures therefore will be required. The most practical of these is to increase CO sub(2) sinks through photosynthesis in both standing tree biomass and in ocean primary producers. In this paper, the use of marine algae as CO sub(2) sinks is reviewed from a technical, engineering/economic, and environmental perspective. Two open ocean options are considered for large-scale CO sub(2) mitigation: the use of phytoplankton through Fe fertilization and macroalgal (kelp) farms, which can be used for both C sequestering and energy production.

AN - 16232075; 2763017 AB - This study investigated soil-gas contamination and the mechanisms of entry of VOC into a house with a basement sited adjacent to a municipal landfill. The VOC were identified and quantified in the soil gas and in indoor and outdoor air. Pressure coupling between the basement and the surrounding soil was measured. Using soil-gas tracers, the pressure-driven advective entry of soil gas was quantified as a function of basement depressurization. From the measurements, estimates were made for the diffusive and advective entry rates of VOC into the house. A comparison of the chlorinated hydrocarbons found in soil gas at the site and in the landfill suggests that the landfill is the source of the halogenated compounds in the vicinity of the house.

Specific dam and dcm sites on the E. coli chromosome were found to be unmethylated in vivo by using pulsed-field gel electrophoresis experiments scanning megabase regions of DNA. Some sites were totally unmethylated. The dam sites display variable methylation depending on the local sequence, and, in general, their methylation shows complex modulation by growth conditions and growth rate, suggesting multiple protection mechanisms. Sites resistant to complete dam or dcm methylation appear to be distributed throughout the chromosome.

AN - 16117855; 2667083 AB - The addition of yellow phosphorus in wet scrubbing systems can result in the high efficiency simultaneous removal of SO sub(2) and NO sub(x) from flue gas. Yellow phosphorus reacts with O sub(2) to produce O sub(3) which selectively oxidizes NO to NO sub(2). Subsequently, NO sub(2) and SO sub(2) are removed from flue gas by dissolution into an aqueous alkaline solution/slurry, where they are converted to ammonium sulfate and gypsum. Yellow phosphorus is oxidized to yield a desirable commercial by-product, phosphoric acid.

In two of the cores a complete sequence was observed in argillic alteration of tuffaceous rocks, passing from smectite (often with kaolinite), to mixed-layer illite-smectite (I/S), to illite with increasing depth. Parts of the sequence were observed in the other cores. Lower-permeability rhyolitic lavas typically showed much sparser clay alteration than tuffs. In cores where alteration of smectite to I/S or illite was seen the distribution of the clay minerals, and of compositional and structural variation in the I/S phase, allowed estimation of pre-existing alteration T and thermal gradients. Present T in zones of I/S or illite alteration, including the present-day, high thermal-gradient intervals in SR and PLV-1, are well below pre-existing alteration T. In SR the alteration thermal gradient in the I/S zone was > twice what it is today, and the T >= 65 degrees C higher. The difference between past and present T probably diminishes in the illite zone below, and may be small in the deeper part of the hole. It appears that in PLV-1 high-T circulation has ended, or receded to below the bottom of the hole. Alteration T in the deeper part of INYO-4, although lower than in SR or PLV-1, were also higher in the past than they are now, and the present high gradient at shallower depth may be a remnant of a palaeo-gradient that once persisted to greater depth. T in MLGRAP-1 were probably >= today's.

Five thermal waters display (super 87) Sr/ (super 86) Sr of 0.7081-0.7078 but show systematically lighter values from W to E in the direction of lateral flow. It is believed this decrease signifies increased interaction of deeply circulating thermal water with relatively fresh volcanic rocks filling the caldera depression. All types of pre-, syn-, and post-caldera volcanic rocks in the W and central caldera have ( (super 87) Sr/ (super 86) Sr) (sub m) of approx 0.7060 and 0.7072; values for Sierra Nevada granodiorites adjacent to the caldera are similar. Sierran pre-intrusive metavolcanic and metasedimentary rocks can have much higher Sr-isotope ratios. Hydrothermally altered volcanic rocks inside the caldera have ( (super 87) Sr/ (super 86) Sr) (sub m) slightly heavier than their fresh volcanic equivalents and hydrothermal calcites (0.7068-0.7105) and occupy a mid-range of values between the volcanic/plutonic rocks and the Sierran metamorphic rocks. The data indicate that the Long Valley geothermal reservoir is first equilibrated in a basement complex that contains at least some metasedimentary rocks. Re- equilibration of Sr-isotope ratios to lower values occurs in thermal water as convecting geothermal fluids flow through the isotopically lighter volcanic rocks of the caldera fill.

Lithologic and O-isotope data for eight wells are presented, along with reconnaissance O-isotope data for volcanic and basement rocks from surface exposures in the area. Measured down-hole O-isotope profiles are compared with model O- isotope profiles, calculated using the current T logs for the wells. Parts of some wells have closely approached O-isotope equilibrium with currently circulating fluids, identifying these sites as natural laboratories for investigations of active hydrothermal processes. Conversely, regions of fossil hydrothermal circulation and alteration provide a clear picture of fossil circulation patterns. The O-isotope profiles are also useful in estimating the longevity of current hydrothermal circulation, identifying areas of lateral fluid flow, determining the vertical extent of the geothermal reservoir at drilled sites, and understanding the geological controls on past and present fluid circulation systems of the caldera.

The state-of-the-art and possible directions of further research in these coupled processes are discussed. Rock fracture behaviors considered include not only dilation, closure, shear, and joint propagation but also changes in flow permeability and chemical sorption and retardation capabilities. These properties are of critical concern in practical considerations of the rock mass as a medium to store and isolate chemical and radioactive wastes. Investigations of coupled processes in two-fracture systems and multifracture systems are identified as important areas for future research. The need to consider coupled processes in borehole testing procedures involving rock fractures is emphasized. Copyright 1991 by the American Geophysical Union.

The results show that the boundary interval holds one of the highest Ir enrichments (320 ng Ir/cm (super 2) ) of all known Cretaceous/Tertiary boundary layers. Iridium concentrations are highest (18 ppb Ir, whole-rock samples) a few centimeters above the base of the clay-rich interval and gradually tail off upsection. Compared with background levels the most Ir-rich interval also shows strongly enhanced concentrations of Cr (215 ppm) and slightly elevated Co concentrations (13 ppm). Rare earth element (REE) abundance patterns change considerably across the Cretaceous/Tertiary boundary interval, reflecting either a change in Cretaceous/Tertiary boundary seawater REE composition or the occurrence of different REE fractionation processes due to changing depositional environment.

The change of the calcareous nannoflora and of the planktonic foraminifers is spread over a laminated interval of about 15 cm thickness. The base of this interval lies in uppermost Maestrichtian chalks, 2 cm below a distinct 2 mm-thick "gray clay" layer, which shows the highest iridium enrichment (18 ppb) measured in this section. No shocked quartz or microspherules, characteristic of an impact, were found. No change in the clay mineralogy, which might be expected for a large volcanic or impact event, could be identified. Elevated metal and iridium concentrations (1.6 ppb) occur already in the bioturbated uppermost Maestrichtian chalks several centimeters below the "gray clay" and decrease above the iridium peak gradually over a laminated 12 cm-thick interval to background values of 0.1-0.3 ppb Ir. Application of bio- and magnetochronology shows that the accumulation rates of carbonates and clays, but not of the metals, decreased dramatically at the Cretaceous/Tertiary boundary, hence the lack of dilution may have led to the observed metal concentrations.

Furthermore, the shape of these curves may change when the injection flow rate is varied. In this paper the conditions under which the breakthrough curve may present multiple peaks are analyzed numerically using stochastically generated fractures. The dispersivities of these peaks are also calculated. It is found that the dispersivity is small for each of the peaks and that the dispersivities of the different peaks in a breakthrough curve are quite similar. The results presented in this paper may be equally applied to tracer tests in a two-dimensional strongly heterogeneous medium. Copyright 1991 by the American Geophysical Union.

Under such conditions, negative correlations were documented between aqueous Se and Fe (super 2+) , Mn, and H (sub 2) S. Locally, the presence of oxidizing species, notably O (sub 2) and NO (sub 3) , suppressed this reduction, permitting Se mobilization in the shallow aquifer. Selenate, the dominant and most oxidized form of Se, was in electrochemical disequilibrium with subordinate concentrations of selenite. Normally slow inorganic reduction rates were accelerated by microbial activity which utilizes oxidized chemical species including selenate as electron donors during the oxidation of organic matter. Two stratified redox barriers to selenium migration were documented beneath Kesterson: an underlying shallow anoxic zone underlying most of the pond bottom, characterized by high organic content and sulfate reduction, and a deeper dynamic front established by localized O (sub 2) infiltration from the overlying ponds and Fe (super 2+) release from aquifer materials. The reducing nature of this deeper aquifer ultimately precludes Se transport to regional groundwater. Copyright 1991 by the American Geophysical Union.
