TY - JOUR T1 - Exposure temperature, but not donor age, is a confounding factor for in vitro translocation production by chronic irradiation. AN - 69884219; 10404996 AB - PURPOSETo assess the effects of incubation temperature during irradiation, and of donor age, on the in vitro induction of chromosomal translocations in human lymphocytes.MATERIAL AND METHODSLymphocytes from six human male donors were scored, using fluorescence in situ hybridization, for the presence of chromosomal translocations involving chromosomes 1 to 6 after in vitro, chronic exposure (delivered continuously over 48 h at 37 degrees C or at 20 degrees C) to tritium beta-rays or 60Co gamma-rays.RESULTSNo age-related difference in the alpha coefficients of the fitted induction curves was observed for gamma-ray-exposed lymphocytes obtained from four donors whose ages ranged from 24 to 79 years, or for tritium beta-ray-exposed lymphocytes from two donors aged 36 and 62 years. Duplicate samples from one donor, irradiated concurrently at 20 degrees C or 37 degrees C, gave significantly different alpha coefficients: 0.128+/-0.008 and 0.053+/-0.004, respectively (p<0.0001). The S-ratio (the ratio of induced complete to incomplete translocations) was found to be independent of radiation dose, donor age and exposure temperature.CONCLUSIONSFor biodosimetry in chronic irradiation situations, the use of alpha coefficients derived from the dose-response curves of cells chronically irradiated in vitro at body temperature is recommended. With respect to induction rates, donor age does not appear to be a confounding factor. The S-ratio is independent of radiation doses, exposure temperatures, or donor ages.

AN - 69852149; 10385140 AB - Epidemiology studies have indicated that certain dietary components, including well-cooked meat, are risk determinants for colon cancer. Cooked meat can contain significant quantities of heterocyclic aromatic amines (HCAs), which have been established as carcinogens in laboratory animals. 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is usually the most mass-abundant HCA, with concentrations up to 480 ppb. We used accelerator mass spectrometry to establish whether DNA and protein adducts can be detected in humans exposed to a quantity of PhIP comparable with levels of exposure that occur in the diet. Five human volunteers were administered a dietary-relevant dose of [14C]PhIP (70-84 microg) 48-72 h before surgery for removal of colon tumors. Blood samples were collected at various time points, and albumin, hemoglobin, and WBC DNA were extracted for analysis by accelerator mass spectrometry. Tissue samples were collected during surgery and used to assess either tissue available doses of [14C]PhIP or adduct levels. The results of this study show: (a) PhIP is activated to a form that will bind to albumin, hemoglobin, and WBC DNA in peripheral blood. WBC DNA adducts were unstable and declined substantially over 24 h; (b) PhIP is bioavailable to the colon, with levels in normal tissue in the range 42-122 pg PhIP/g tissue; and (c) PhIP binds to both protein and DNA in the colon. DNA adduct levels in the normal tissue were 35-135 adducts/10(12) nucleotides, which was significantly lower than tumor tissue. The results of this study demonstrate that PhIP is bioavailable to the human colon following defined dietary-relevant doses and forms DNA and protein adducts.

AN - 69764584; 10332518 AB - Eighty computer users with musculoskeletal disorders participated in a 6-month, randomized, placebo-controlled trial evaluating the effects of four computer keyboards on clinical findings, pain severity, functional hand status, and comfort. The alternative geometry keyboards tested were: the Apple Adjustable Keyboard [kb1], Comfort Keyboard System [kb2], Microsoft Natural Keyboard [kb3], and placebo. Compared to placebo, kb3 and to a lesser extent kb1 groups demonstrated an improving trend in pain severity and hand function following 6 months of keyboard use. However, there was no corresponding consistent improvement in clinical findings in the alternative geometry keyboard groups compared to the placebo group. Overall, there was a significant correlation between improvement of pain severity and greater satisfaction with the keyboards. These results provide evidence that keyboard users may experience a reduction in hand pain after several months of use of some alternative geometry keyboards.

The main advantage of the method is its ability to automatically find a suitable network structure and naturally correctly identify explosions as such. The explosion site recognition was done using extracted waveform attributes of various kind event records from the small-aperture array FINESS in Finland. The recognition was done by using P-S phase arrival differences and rough azimuth estimates to provide a first robust epicentre location. This, in turn, leads to correct mining district identification where more detailed tuning was performed using different phase amplitude and signal-to-noise attributes. The explosions studied here originated in mines and quarries located in Finland, coast of Estonia and in the St. Petersburg area, Russia. Although the Helsinki bulletins in 1995 and 1996 listed 1649 events in these areas, analysis was restricted to the 380 (ML> or =2) events which, besides, were found in the reviewed event bulletins (REB) of the CTBTO/UN prototype international data centre (pIDC) in Arlington, VA, USA. These 380 events with different attributes were selected for the learning stage. Because no "ground-truth" information was available the corresponding mining, "code" coordinates used earlier to compile Helsinki bulletins were utilized instead. The novel self-organizing method was tested on 18 new event recordings in the mentioned area in January-February 1997, out of which 15 were connected to correct mines. The misconnected three events were those which did not have all matching attributes in the self-organizing maps (SOMs) network.

Etna Volcano and in the Acri region (southern Italy) AN - 52465252; 1999-046938 AB - The PC-based automatic seismic data processing (ASDP) software module uses a multi-algorithm approach and a new procedure (MSA) for signal detection, phase grouping and event identification and location. It is designed for an efficient and accurate processing of local earthquakes records provided by single-site and array stations. Results from ASDP processing of two different data sets are analysed to evaluate its performance. By comparing of ASDP pickings with those revised manually the detection and subsequently the location capabilities of this software are assessed. The first data set is composed of 330 local microearthquakes (1.7< or =M< or =3.8) recorded in the Mt. Etna volcano area by a telemetered analog seismic network. Digital data conversion of data is performed at the network centre operated by the Istituto Internazionale di Vulcanologia of C.N.R. The second data set comprises 40 ultra-microearthquakes (0.5< or =M< or =2.0) recorded by a temporary array of four digital three-component stations, deployed in the Acri region (southern Calabria). For the Etnean earthquakes, a comparison of the automatic results with the manual picks indicates that the ASDP module can accurately pick 80% of the P-waves (differences are within 0.15 s) and 65% of the S-waves (differences are within 0.3 s). A peculiarity for these events is that the majority of the 3 three-component station records do not exhibit distinct S-waves. This statistics includes records with a strong noise (ground tremors and/or system electronic disturbances), but does not include false alarms due to non-seismic signals. Conversely, if we consider high-dynamic recordings of seismic digital data in a low-noise environment (Acri temporary array) the ASDP module can accurately pick 93% of the P-waves (differences with manual estimations are less than 0.1 s) and 87% of the S-waves (differences with manual estimations are less than 0.2 s). For this type of data with a favourable signal-to-noise ratio the automatic back-azimuths estimates are also extremely accurate in the 87% of the cases (differences estimations with those revised by an analyst and deriving from hypocenter solutions are generally within 10 degrees ). In general, our results indicate that both automatic ASDP and manual hypocenter locations are comparable within the estimated errors bounds. Furthermore, the comparison of ASDP automatic locations with those performed by XRTP-IASPEI software, routinely used for automatic locations at the Mt. Etna seismic network, indicates a better performance of the ASDP module.

In some countries, the local seismicity is equivalent to felt earthquakes but the problem remains since both earthquakes and explosions are and will be recorded by local stations. These events will therefore enter the network data center processing system, and thus, be subjected to further analysis. Source classification schemes are not always well suited for this kind of needed analysis at local distance ranges (not easily transportable). Besides, epicenter determinations may be less accurate in cases of few station reportings. The common denominator for failures is the modest usages of the information potential contained in seismic recordings being represented by a few time/amplitude parameters for the Pn- and Lg-phases. On the other hand, seismic waveform similarities for closely spaced earthquakes and explosions in particular are well established observationally. In this study period, we explore the possibility of using single station three-component (3C) covariance matrix traces from a priori known explosion sites (learning) for automatically recognizing subsequent explosions from the same site. To ensure adequate sampling, we used the nine different complex covariance time domain elements in combination with a suit of 12 bandpass filters equivalent to 108 observation pieces for a single event recording. We used a neural net scheme for teaching the computer to recognize new explosion recordings from a specific site through scanning of hundreds of detector segmented waveform files. No epicenter information was used in this analysis. The output was a single number between Zero and Four (log-scale) with an acceptance threshold (repeated explosion) of 1.2-analyst friendly usage. Actual tests were performed on two explosion sites of western Norway for which ground truth information was available. The 100% correct decisions were obtained between "site explosions" and hundreds of non-site events. A brute force test on the relative merits of the 12 frequency bands used gave that the 2-4 Hz and 8-12 Hz spectral parts were most informative. Experiment tied to two quarry sites for which ground truth information was lacking gave less sharp separation of site and non-site events. Since covariance elements comprise P- and S-waveform jointly, good spatial sampling is ensured even for single site 3C stations; beyond 10 km from the epicenter the scores were in the non-site category. The above approach to event discrimination is very flexible as we may combine several 3C stations with even z-component stations and besides, no analyst action in any way will be needed.

Several large and complex software packages for automatic and interactive analysis of seismic data have been developed in recent years mainly for UNIX-based systems, and some of these programs use a variety of artificial intelligence techniques. Here, the first operational version of a new software package, named PC-Seism, for analyzing seismic data from a local network is presented. This package, composed of three separate modules, provides an example of a new generation of visual object-oriented programs for interactive and automatic seismic data processing run on a personal computer. In particular, we discuss the automatic procedures implemented in the ASDP (Automatic Seismic Data Processing) module. A multi-algorithm approach to the on-line detection and location of local earthquakes is adopted in ASDP, and its operative mode is similar to that used in more complex systems, where the algorithms run on different processors and parallel computations are generally performed. Since highly complex computation routines may still be prohibitive for current PC when the number of analyzing traces becomes large, we have opted for simplicity and have planned three main routines (working in cascade mode) and a multi-station analysis (MSA) procedure in ASDP, to recognize phase picking, declare and locate earthquakes. Basically, signal detection on a single-component trace is obtained by a short-term average to long-term average ratio (STA/LTA) taken along a characteristic function (CF) envelope generated from the seismogram. To confirm and identify earthquake phase arrivals and to discard noise disturbances, two other sections of analysis are applied on short signal windows after the declared triggers. A spectral analysis is applied as detector of earthquake phase arrivals. Furthermore, for three-component data, the application of a polarization filter is used to identify P- and S-phases. Therefore in order to optimize the efficiency of a seismic monitoring system, the software is provided with full detection capability and makes use of a high degree of automation, aimed at minimizing the analyst's workload. PC-Seism and, in particular, the ASDP module are under constant review. In fact, the modular structure of the program will allow us to develop it with new and improved capabilities. Future developments improvements in ASDP will concern the application of other detection algorithms and routines to recognize secondary phases in regional and teleseismic earthquakes.

Being a very useful tool for frequency content studies, the spectrogram method sometimes failed to recognize ripple-fired or spatially separated mine blasts. Due to short delays commonly used (20-40 ms) and complicated crust structure in the region, prominent spectral scalloping of the spectrogram is not observed regularly and is not coherent at different stations. Mean vertical-component Pg/Lg spectral ratio in the band 8 to 20 Hz serves quite well as a discriminant but its value, in general, significantly depends on the particular mine and epicenter location. We have found that no single method can yet assure reliable discrimination between seismic signals from earthquakes and explosions in this region. A self-training algorithm, based on the comparison of "demeaned" envelopes, which grouped events by means of hierarchical cluster analysis, P/S discriminant, was implemented to classify a data set of 18 months of routine observations. A total of 366 out of 374 records were successfully classified and separated into 19 groups of events. This algorithm is especially useful when data analyzed are from sparse networks or from a region of complicated crust structure where averaging over the network can lead to systematic error.

In this study, we have demonstrated the quadratic neural network (QNN) potential capabilities in application to the seismic signal classification problems and show that the efficiency achieved here, is much better to what obtained with conventional multilayer neural networks. Firstly, we have performed some pre-processing on the long period recordings to cancel out the instrumental and attenuation side effects. Secondly, we have extracted the ARMA filter coefficients of the windowed P-wave phase through some matrix manipulations using the conventional Prony ARMA modeling scheme. The derived coefficients are then applied to QNN for training and classification. The results have shown that a quadratic neuron is likely to have a performance similar to that of a multilayer perceptron when the target is to discriminate distribution of points in clusters within the input space.

The method is used for step-by-step testing of candidate discrimination features to find the optimum (combination) subset of features, with the decision taken on a rigorous statistical basis. Linear (LDF) and Quadratic (QDF) Discriminant Functions based on Gaussian distributions of the discrimination features are implemented and statistically grounded; the features may be transformed by the Box-Cox transformation z = (1/alpha )(y (super alpha ) -1) to make them more Gaussian. Tests of the method were successfully conducted on seismograms from the Israel Seismic Network using features consisting of spectral ratios between and within phases. Results showed that the QDF was more effective than the LDF and required five features out of 18 candidates for the optimum set. It was found that discrimination improved with increasing distance within the local range, and that eliminating transformation of the features and failing to correct for noise led to degradation of discrimination.

We have performed new (super 36) Cl, (super 26) Al, (super 10) Be, and noble gas measurements, including determination of the shielding parameter, S = (super 4) He/ (super 21) Ne, in samples with published K data. The K isotopic data, coupled to (super 36) Ar and (super 36) Cl concentrations permit selection of meteorites which have only experienced simple (constant geometry) irradiation histories. These objects can be used for the calibration of shielding-dependent production rates within these metallic detectors. In order to carry out production rate calibrations based on (super 40) K- (super 41) K data, we assume constancy of the cosmic flux during the interval 150 to 700 My ago. We note that meteorites with very old potassium ages cannot be included in this calibration, as these meteorites require distinct parameter sets. A calibration data set representing a total of 13 meteorites was used to compute long-term (0.5 Gy) average production rates. These average production rates of (super 36) Cl from this particular calibration set are significantly (28%) lower than those determined for the recent (< or =10 My) cosmic ray flux. We also document here the quality of the resulting potassium production rate parameter M (sub 0) (S) with a calculated isochron for irons of group IVA.

Using events with lower signal-to-noise ratios (SNR) would increase the amount of data from these regions. Lower SNR events can add significant numbers to data sets, but recordings of these events must be carefully filtered. For a given region, conventional methods of filter selection can be quite subjective and may require intensive analysis of many events. To reduce this laborious process, we have developed an automated method to provide optimal filters for low SNR regional or teleseismic events. As seismic signals are often localized in frequency and time with distinct time-frequency characteristics, our method is based on the decomposition of a time series into a set of subsignals, each representing a band with f/Delta f constant (constant Q). The SNR is calculated on the pre-event noise and signal window. The band pass signals with high SNR are used to indicate the cutoff filter limits for the optimized filter. Results indicate a significant improvement in SNR, particularly for low SNR events. The method provides an optimum filter which can be immediately applied to unknown regions. The filtered signals are used to map the seismic frequency response of a region and may provide improvements in travel-time picking, azimuth estimation, regional characterization, and event detection. For example, when an event is detected and a preliminary location is determined, the computer could automatically select optimal filter bands for data from non-reporting stations. Results are shown for a set of low SNR events as well as 379 regional and teleseismic events recorded at stations ABKT, KIV, and ANTO in the Middle East.

The semblance and the average spectral ratio of low-to-high frequency energy were evaluated, using a subset of 7-10 stations for a given event. Semblance and spectral ratio values, calculated from ISN seismograms, were found to be higher for earthquakes, where the analyzed waves are richer in low-frequency energy and have more coherent spectral shapes than explosions. These observations are contrary to those observed for local events. The best performance is provided in the frequency bands (0.6-1 Hz)/(1-3 Hz) (for the ratio) and (0.6-2 Hz) (for the semblance). Joint application of the two discriminants showed almost full separation (95%) between the two populations. Some explosions exhibited pronounced minima (nulls) near 1 Hz which could be interpreted in terms of interference of P- and pP-waves from a source at the depth of several hundreds of meters. Nevertheless, this feature could not be utilized as a discriminant: many explosions revealed strong variability of this minimum across the ISN network and some earthquakes also distinctly exhibited this feature. The ISN and NORESS discrimination performances were compared. The latter records showed the same (as the ISN) relation between spectral ratio values for earthquakes and explosions, whereas the character of semblance was reversed. The ratios in the frequency bands (0.6-0.8 Hz)/(0.6-10 Hz) yield full separation of the two populations. In general, the spectral ratio performance appears to be better for NORESS recordings, whereas the spectral semblance is better for the ISN data.

Mawson signals are continuously transmitted to the National Data Center (NDC) in Canberra and also forwarded to the International Data Centre (IDC) in Washington, where further event analysis is performed. Numerous seismic signals are recorded on seismograms from the Mawson station, with a likely mechanism of sudden fracturing of ice. The aim of this study was to find a procedure which will effectively discriminate seismic signals from these icequakes and thus speed up the analysis of the other detected events. An automatic algorithm was designed to identify icequakes according to their characteristics: frequency content, duration, azimuth, inclination and magnitude. The program was tested on a few datasets of randomly selected periods and one comprised of records of nuclear explosions detonated in the period of 1995/96. The preliminary results showed that this method was capable of distinguishing icequakes and could substantially improve the production of an automated event list.

The automatic, on-line, earthquake analysis performed by the SIL network can be divided into three categories. (1) Single-station analysis performed at the site stations producing information about all incoming phases. A short message with data on the phase is sent to the center. (2) Multi-station analysis done at the center, using the phase reports from the stations and producing information about all detected events including estimates of location, magnitude and fault plane solutions. (3) Alert reporting to notify the operators of the network in cases of a priori defined changes in parameters derived from the single- and multi-station analysis. The system is designed for maximum automatic operation and minimum operational cost and has shown to be capable of automatic evaluation of more then 1000 earthquakes per day or episodically several earthquakes per minute. While no attempt is made to detect and locate teleseismic events, teleseismic data is automatically saved, based on e-mail messages from global seismological networks. Groups of events are analyzed using correlation techniques to obtain accurate absolute and relative locations of earthquakes with similar waveforms. In some areas within the network, most of the earthquakes correlate very highly with each other. Based on this a new approach is being taken regarding the automatic operation of the network. A geographically indexed data base will be created where different classes of earthquakes are stored. As new earthquakes are recorded by the network the system automatically looks for similar waveforms in this data base and, if found, takes the onset and first motion direction picks from there. The algorithm is planned to be implemented in late 1999. New methods have been developed to estimate the stress tensor based only on the microearthquake focal mechanisms and accurate relative locations. This is planned to be implemented into the automatic on-line procedures. Methods and related software are being developed for real-time monitoring of fault movements based on the high accuracy locations and fault plane solutions.

The organization is unique in its field, because it does not operate any stations, but acts as an intermediate between data users and data producers. The core activity of ORFEUS is the operation of a data center, which archives seismic waveform data of large seismic events and offers both off-line (CD-ROM) and on-line (Internet, WWW) access to both the archived data and global near real time Spyder (super R) data. ORFEUS coordination function is largely realized through its working groups and web site, which presently provide, among others, station siting and equipment overviews, technical information and support and a Seismological Software Library (SSL). Cooperation with other centers, for example, on data formats, is coordinated through the Federation of Digital Seismograph Networks (FDSN). Future developments emphasize improved data access through the Internet (WWW, Automatic Data Request Manager, NetDC protocol) and a regional version of the Global Spyder (super R) : EuroSpyder. Regularly, work meetings and workshops are organized to discuss future developments and its impact on ORFEUS.

The method consists of the computation of the cumulative sum (CUSUM) of a test statistic, in this case, the absolute value of the trace amplitude, addition of a linear trend to the result and finding minima of the resulting function by various methods. The minima are located at the times where sudden increases in the trace amplitudes occur, i.e., at the phase onsets. The method requires frequency prefiltering in order to enhance the amplitude changes at the phase onsets. It was found that this algorithm performed comparably to a human analyst in finding onset times for Pn arrivals with varying S/N ratios. Moreover, when applied to the rest of the seismogram, it was effective in finding the onset times of the rest of the regional arrivals as long as these were clearly visible. In the rest of the cases, where there are many poorly defined arrivals, an analyst would also have difficulties in uniquely defining onset times. The method also shares with the human analyst the tendency to pick the onset times late when an emergent arrival is buried in noise.

The testing includes the routine production of a daily bulletin of global seismic activity, several days after real time, since the beginning of 1995. A wider variety of seismic phases are used for location than is the practice of existing agencies producing global bulletins at greater delays, and another difference is that observed slowness vectors are used in addition to arrival time. Comparisons of pIDC bulletins with those provided by national agencies that operate denser networks have demonstrated both random and systematic errors in location that often exceed the formal error estimates. The pIDC is developing and testing techniques to reduce systematic biases through region- and path-dependent corrections to travel-time and slowness, and to better account for random errors. Initial results from this very long-term project are encouraging. JF - Physics of the Earth and Planetary Interiors AU - Bondar, Istvan AU - North, Robert G A2 - Husebye, E. S. A2 - Dowla, F. U.

The representation of a time series with an autoregressive (AR) process of low order can be applied to both multi-component and single-component traces of broadband and short period seismograms. In three-component analysis the AR coefficients are represented as second-order tensors and include potential cross-coupling between the different components of the seismogram. Power spectrum estimation using autoregressive methods is demonstrated to be effective for both signal and noise and has the advantage over FFT methods in that it is smoother and less susceptible to statistical noise. The order of the AR process required to resolve the detail of the spectra is higher for a complex signal than for the preceding noise. This variation in the weighting of the AR coefficients provides an effective way to characterise data in a similar way to Spectragrams and Vespagrams and can be achieved with as few as five AR coefficients. For three-component analysis a display of the nine AR coefficients can be readily organised with three AR-grams for each of the original data components. The various elements of the AR tensor coefficients reflect different changes in the seismogram. The presence of secondary phases is often clearer on a cross-correlation AR-gram (NE or EN) than on the autocorrelation AR-gram (NN or NE). The variations in the weighting of the AR coefficients can be exploited in two different styles of approach to onset time estimation (phase picking). In the first method, two different AR representations are constructed for different portions of the record and the onset time is estimated from the point of transition. In the second method, a single AR representation is constructed and the onset time estimation is based on the growth of a component which is not represented by the AR process. Both methods can be applied to both single and three-component data. For large impulsive P phases, both methods picked the onset time within two samples of the manually estimated onset time. For S phases, where the energy is present on all three components, three-component AR onset time estimation is preferred to that using a single component. The approach is very robust with the three-component method picking the onset time of a very small S phase on a broad-band record to within 0.5 s of the best manual estimate.

The installation is almost complete. The effort has been focused on the accessibility of data from our Data Center. Data can be obtained either on line through the WWW GEOSCOPE server (http://geoscope.ipgp.jussieu.fr), or through our anonymous ftp, or through CD-ROM production or through the IRIS/SPYDER system for large earthquakes. In the near future easier ways will be available, such as autoDRM (automatic Data Request Management) and NetDC requests (Networked Data Centers, protocol proposed by the IRIS DMC of Seattle).

The data include 53 seismic events occurring in northern Israel with magnitudes of M (sub L) = 1.0-2.6 and at distances of 15-310 km. Within the 1-4 km/s range we measured the velocity V (sub ms) at which the envelope reaches its maximum for each ISN station. A simple linear discrimination function c = b+0.33a, based on an empirical relationship between the V (sub ms) and R: V (sub ms) = a+b ln(R) provides effective separation between the regional earthquakes and explosions. These results are attributed to different excitation of regional surface waves from these two types of seismic events.

The (super 13) C/ (super 12) C measurements represent the first global data set with time series records presented for Point Barrow, Alaska (71 degrees N), Olympic Peninsula, Washington (48 degrees N), Mauna Loa, Hawaii (20 degrees N), American Samoa (14 degrees S), Cape Grim, Australia (41 degrees S), and Baring Head, New Zealand (41 degrees S). North-south trends of the (super 13) C/ (super 12) C and D/H of atmospheric CH (sub 4) from air samples collected during oceanographic research cruises in the Pacific Ocean are also presented. The mean annual delta (super 13) C increased southward from about -47.7 per mil at 71 degrees N to -41.2 per mil at 41 degrees S. The amplitude of the seasonal cycle in delta (super 13) C ranged from about 0.4 per mil at 71 degrees N to 0.1 per mil at 14 degrees S. The seasonal delta (super 13) C cycle at sites in tropical latitudes could be explained by CH (sub 4) loss via reaction with OH radical, whereas at temperate and polar latitudes in the northern hemisphere seasonal changes in the delta (super 13) C of the CH (sub 4) source were needed to explain the seasonal cycle. The higher delta (super 13) C value in the southern (-47.2 per mil) versus northern (-47.4 per mil) hemisphere was a result of interhemispheric transport of CH (sub 4) . A slight interannual delta (super 13) C increase of 0.02+ or -0.005 per mil yr (super -1) was measured at all sites between 1990 and 1995. The mean delta D of atmospheric CH (sub 4) was -86+ or -3 per mil between 1989 and 1995 with a 10 per mil depletion in the northern versus southern hemisphere. The (super 14) C content of CH (sub 4) measured at 48 degrees N increased from 122 to 128 percent modern between 1987 and 1995. The proportion of CH (sub 4) released from fossil sources was 18+ or -9% in the early 1990s as derived from the (super 14) C content of CH (sub 4) . Copyright 1999 by the American Geophysical Union.

In our Control simulation, we place all rejected salt in the top ocean-model level. In the Plume simulation, we instantaneously mix rejected salt into the subsurface ocean, to a maximum depth which depends on local density gradients. This mimics the effects of subgrid-scale convection of rejected salt. The results of the Plume simulation are more realistic than those of the Control simulation: the spatial pattern of simulated salinities (especially in the Southern Ocean), deep-ocean temperatures, simulated sea-ice extents and surface air temperatures all agree better with observations. A similar pair of simulations using horizontal tracer diffusion instead of the Gent-McWilliams eddy parameterization show similar changes due to instantaneous mixing of rejected salt.

Mass balances were monitored by measuring both the rate of disappearance of TCE and the rate of appearance of CO sub(2) and Cl super(-). Dilute buffer solutions were used to fix pH and stoichiometrically sufficient amounts of dissolved O sub(2) were used to make the reactions pseudo zero-order in O sub(2). Using a standard chemical kinetic approach, two orders-of-magnitude in initial TCE concentration were spanned and the resulting double-log plot (log concentration vs. log initial rate) was used to determine the rate constant (k = 5.77 plus or minus 1.06x10 super(-7) s super(-1)) and "true" (i.e., with respect to concentration, not time) reaction order (n sub(c) = 0.85 plus or minus 0.03) for the rate law. By determining rate constants over the temperature interval 343-373 K, the Arrhenius activation energy (E sub(a)) for the reaction was determined to be 108.0 plus or minus 4.5 kJ/mol. The rate law and derived kinetic parameters may be used in reactive transport simulators in order to account for aqueous oxidation of TCE as a function of temperature.

Expressions derived from least squares regression analysis of experimental clinopyroxene-liquid pairs describe clinopyroxene-melt equilibria, and allow calculation of equilibrium clinopyroxene compositions. The calibration database includes clinopyroxenes synthesized from natural and synthetic basalt compositions at 0-100 kbar and 1350-2450 K. Empirical expressions were also derived since these provide more precise estimates of clinopyroxene compositions, and may be easily incorporated into existing liquid line-of-descent models. They are also useful for calculation of high P liquid fractionation and for constraining P-T conditions for basalts produced by partial melting of a pyroxene-bearing source. Since models of mantle melting often rely on expressions involving simple element ratios, partition coefficients (K (super cpx/liq) (sub d) ) for Na and Ti were calibrated as a function of P, T and composition. K (super cpx/liq) (sub Na) , while sensitive to composition was relatively insentitive to P and T, whereas K (super cpx/liq) (sub Na) increased substantially with increasing P, being > 1 in some experiments. Since oceanic basalts have variable Na/Ti values, the potential exists for partial melting depths to be inferred from K (super cpx/liq) (sub Na) .

The inorganic N (sub 2) fluxes were computed during 210 days from 1 December 1994 to 30 June 1995, and input to the model included sets of upstream river discharges and solute concentrations and tidal forcings. The computed transient N (sub 2) fluxes are compared to estimates based on an estuarine steady-state assumption for the period when an N (sub 2) -limited Phaeocystis bloom developed in the North Sea; underestimation of the steady-state method is of an order of 100 %.

Its hanging wall consists of conglomerate of the Pliocene Burang Formation, and its footwall is composed of granite-gneiss, granitic mylonite and carbonate mylonite of the Pre-Cambrian Nyalam Group. 208Pb/232Th ion microprobe dating of undeformed and deformed leucogranite emplaced into the mylonite in the footwall of the fault yields ages of 8.0+ or -0.2 Ma and 19+ or -1 Ma respectively, and regional geological data also show that the normal fault is a component part of the large-scale WNW-trending southern Xizang detachment extensional structure developed along the northern slope of the Higher Himalayas. The authors infer that the change of the strike of the extensional fault from NNW to N-S in the Burang Basin and the formation of the basin are related to the right-lateral Karakorum fault system.

The process would be greatly facilitated by a portable instrument that could be used in any suspect location and was capable of rapidly detecting and characterizing microbial pathogens. Nucleic acid analysis is preferable to immunoassays for such a test because detailed genetic information can be obtained about a particular microbe's virulence, antibiotic resistance, and epidemiology. A growing number of these bacterial test use polymerase chain reaction (PCR) because of its demonstrated effectiveness, sensitivity, and reliability. For field use, a variation of standard PCR called real-time PCR is the most practical, because it does not require time-consuming post-PCR manipulation and processing of the reaction with slab gel and capillary electrophoresis, hybridization to immobilized oligonucleotides, or mass spectrometry.

AN - 69757900; 10329906 AB - This chapter reviews the epidemiology, manifestations, etiologic agents, and exposure controls related to occupational allergies from animals and insects, including both respiratory and dermatologic responses. The overall prevalence of allergic respiratory symptoms in exposed workers is about 23% 4-9% of exposed individuals develop asthma. Symptom development is related to duration and intensity of exposure. The most prevalent dermatologic findings are contact urticaria and eczematous dermatitis. While a history of atopy is associated with the risk of symptom development, this factor has poor predictive value for any given individual. Similarly, skin testing and RAST testing are not sufficiently predictive to be recommended as screening tools, although they may identify individuals at some increased risk. The specific tissue sources of the major allergens are reviewed; for laboratory rats and mice, a urinary protein complex has been implicated. Environmental control of antigens is key in the prevention of allergic disease. Task-specific engineering controls, general environmental hygiene, training, and medical surveillance of workers are important elements of the prevention program.

Matrix glasses (MgO approximately 9 wt.%) have H (sub 2) O, Cl, and B contents considerably in excess of the values expected from mantle melting or fractional crystallization of parental Loihi magmas. Glass inclusions have H (sub 2) O, Cl, and B contents ranging from the high values of the matrix glasses to lower concentrations that are more typical of Hawaiian magmas. Concentrations of other incompatible elements (e.g., K (sub 2) O, P (sub 2) O (sub 5) , and Be) in matrix glasses and glass inclusions are uncorrelated with their H (sub 2) O, Cl, and B contents. Glass inclusions show considerable scatter in major element compositions compared to matrix glasses, but except for H (sub 2) O, Cl, and B, the average glass inclusion composition corresponds well to the matrix glass compositions. We propose that the glass inclusions represent compositionally diverse liquids present within the magmatic plumbing system at Loihi that were mixed and homogenized to produce the liquid that quenched to the matrix glass on eruption. This range of liquid compositions present at depth was trapped by crystallizing olivine prior to blending and homogenizing and therefore preserves a compositional diversity not present in erupted whole rocks. The high H (sub 2) O, Cl, and B contents of matrix glasses and some glass inclusions, and the range of H (sub 2) O, Cl, and B concentrations in glass inclusions, are best explained by variable extents of assimilation by Loihi magmas of H (sub 2) O-Cl-B-rich, seawater-derived components prior to eruption. The required assimilants range from material similar in composition to seawater to materials with Cl/H (sub 2) O and B/H (sub 2) O ratios much higher than seawater. Our preferred explanation (similar to that suggested for MORB by Michael and Schilling, 1989) [Michael, P. J., Schilling, J. G., 1989. Chlorine in mid-ocean ridge magmas: Evidence for assimilation of seawater-influenced components. Geochim. Cosmochim. Acta, 53, p. 3131-3143.] is that most of the assimilated materials were brines (or rocks containing brines in inclusions or along grain boundaries) enriched in Cl by high temperature phase separation of seawater in sub-sea-floor hydrothermal circulation systems. Addition of approximately 1.0 wt.% of a 15 wt.% NaCl brine can explain the H (sub 2) O and Cl contents of the matrix glasses. Addition of altered basalt cannot readily account for the Cl and H (sub 2) O contents of matrix glasses and glass inclusions, but may be required to account for their elevated B contents. The enrichment in Cl and contamination with atmospheric noble gases observed in other samples from Loihi could also result from assimilation of Cl-enriched, seawater-derived components.

Isotope closure temperatures in buffered rocks are intermediate between simpler predictions based on "wet" (1 kbar hydrothermal) and "dry" (P<1 atm, H (sub 2) O-absent) diffusion experiments, but are typically within approximately 50 degrees C of closure temperature estimates that use "wet" diffusion rates, yet 200-300 degrees C different from "dry." Even though many rocks may be "dry" in that they lack a hydrous fluid that is physically present during cooling, buffering of f (sub H2O) results in quasi-"wet" diffusion rates. Re-evaluation of published data shows that most rocks indeed exhibit substantial isotope resetting that is best matched by predictions of f (sub H2O) -buffering models. Wet- and dry-diffusion models somewhat overestimate and greatly underestimate resetting respectively. Previous interpretations invoking "dry" diffusion rates may derive from erroneous fractionation factors or faster cooling rates than assumed. The rare preservation of isotope closure temperatures that are higher than predicted may reflect faster than expected cooling rates or extraordinarily low f (sub H2O) in conjunction with anhydrous assemblages.

One objective of this experiment was to evaluate the effect of differing source depth on the regional wave field. Analysis of regional seismic phases lead to the observation that regional P/S wave amplitude ratios in the 1- to 5-Hz band increase as a function of source depth. However, at frequencies greater than about 5 Hz, the relative amplitudes of P and S waves remain approximately constant for the differing depth shots. Similarly, regional coda spectra are amplified in the 1- to 5-Hz band for the shallow shots. At local distances, Rg is the dominant seismic phase, with peak amplitudes in the 0.7- to 5-Hz range, and Rg is strongest for the shallower shots. Within the short distance spanned by the local stations (<20 km), Rg is rapidly attenuated, and the attenuation is accompanied by a significant shift in peak amplitude toward lower frequency. At regional distances, Rg is below the noise level. The coincident frequency band in which local Rg rapidly loses energy and regional S phases are amplified points toward Rg scattering as the dominant mechanism causing the discrepancies between P/S amplitude ratios in this study. These observations are particularly relevant to the understanding of physical processes affecting regional P/S discriminants and may lead to improvements in discriminant methods.

However, propagation path effects lead to variability in regional-phase amplitudes that, if not accounted for, can reduce or eliminate the ability of P/S ratios to identify the seismic source. Here we compare four different methodologies that account for the effect of heterogeneous structure on P/S amplitude variance: (1) distance corrections, (2) path-specific crustal wave-guide parameter regressions, (3) cap averaging (running mean smoothing), and (4) kriging. The predictability of each method is established by cross-validation (leave-one-out) analysis. We apply these techniques to Pn/Lg, Pg/Lg, and Pn/Sn observations in three frequency bands from 0.75 to 6.0 Hz at station ABKT (Alibek, Turkmenistan), site of a primary station of the International Monitoring System (IMS). Paths to ABKT sample diverse crustal structures (e.g., various topographic, sedimentary, and geologic structures), leading to great variability in the observed P/S amplitude ratios. For these data to be useful for isolating source characteristics, the scatter needs to be reduced by accounting for the path effects, and the resulting distribution needs to be Gaussian for most existing spatial interpolation and discrimination strategies to have valid application. Each method reduces the scatter of the P/S amplitude measurements with varying degrees of success; however, kriging has the distinct advantages of providing the greatest variance reduction and a continuous correction surface with an estimate of the model uncertainty. The largest reductions in scatter are found for the lowest frequency P/S ratios (<3.0 Hz).

Stable isotope characterization can contribute needed information on the formative mechanisms of malachite by establishing the source materials and temperature of formation. The equilibrium (super 18) O and (super 13) C isotope fractionations between malachite (super *) and water and between CO (sub 2) gas and malachite were determined by slow precipitation experiments over the temperature range 0 to 50 degrees C: 1000 ln alpha Oxygen mal (super AK) -water = 2.66 (10 (super 6) /T (super 2) ) + 2.66 and 1000 ln alpha Carbon CO (sub 2) -mal = -1.85 (10 (super 6) /T (super 2) ) + 10.51 where temperature (T) is in Kelvin, and where mal (super *) represents the acid liberated CO (sub 2) corrected as total calcite oxygen. This internally consistent method renders the acid correction unnecessary for application of the mal (super *) -water thermometer. Natural malachites have delta (super 18) O and delta (super 13) C values that are similar to those for caliches and speleothems. This similarity supports the field evidence of malachite forming caliche-like crusts and speleothem-like structures, and bears upon the conditions of its genesis. The delta (super 18) O values of +18 to +31 per mil standard mean ocean water (SMOW) for natural malachites are dominantly controlled by the delta (super 18) O values of ambient meteoric waters and the surface temperatures. Most malachites have delta (super 13) C values between 0 and -21 per mil Peedee belemnite (PDB) reflecting a combination of vegetation-respired soil CO (sub 2) and carbonate rock-derived carbon. A strong correlation between the delta (super 18) O values of malachites and local modern meteoric waters suggests that malachites are relatively young, or alternatively, that they are easily exchanged. Using the mal (super *) -water thermometer, formation temperatures of 5 degrees to 35 degrees C are estimated. These temperatures correlate reasonably well with the modern local air temperatures. However, samples from massive sulfide deposits such as Broken Hill, Australia, have estimated temperatures as high as 58 degrees C, probably reflecting the heat generated by sulfide oxidation during weathering.

Overpressured fluids commonly emerge from high elevation springs in these areas, having a typical basinal fluid character. For example, in the Rumsey Hills, springs are saline (up to 2 wt. percent NaCl) and have isotopically enriched delta (super 18) O values (-7.5 to +5.0 per mil; Davisson et al., 1994). delta (super 11) B decreases from +39.5 to +21.5 per mil as boron concentrations increase from 4 to 200 ppm, consistent with boron desorption from clays at approximately 100 degrees C. Similar temperatures calculated from chemical geothermometers suggest fluid sources of approximately 4km . (super 87) Sr/ (super 86) Sr ratios of dissolved Sr decrease from 0.70702 to 0.70585 with increasing Ca/Na ratios, consistent with active plagioclase albitization at similar depths. However, two (super 3) He/ (super 4) He ratios (Ra = 0.2 and 1.9) measured in natural gases effervescing from springs indicate significant mantle contribution and possible fluid sources >>4 km. The saline spring discharge can be related to volume strain, such as pore volume dewatering in undeformed sediments within the wedge. This type of fluid expulsion has been shown in similar areas to occur aseismically within fault-bounded blocks (Melchiorre et al., 1999). However, at depth sediments are likely already dewatered and fluid transport probably occurs along faults rooted to the mantle. Additional evidence is inferred from CO (sub 2) -rich saline waters emerging as springs from Great Valley rocks approximately 40 km north of Mt. Diablo. The delta (super 13) C of the CO (sub 2) (-5.0+ or -1.0 per mil) in equilibrium with high dissolved inorganic carbon (up to 8300 ppm) is similar to known mantle values.

The overpressured fluids emerge at high elevations (to 1500') as geochemically distinctive, high- (super 18) O springs and have resulted in numerous blowouts. From west to east, fluid chemistry grades from CO (sub 2) -rich, travertine-depositing springs and mud volcanoes, to chloride-rich springs that deposit halite, and finally to overpressured, chloride-rich, subsurface fluids commonly associated with oil or gas. Fluid chemistry parallels the change in the predominant tectonic character from strike-slip dominated in the western Coast Ranges to the fold and thrust structures of the eastern Coast Ranges, and ultimately to the Sacramento Valley.

Hydrocarbon gas geochemistry provides evidence that gases from onshore gas seeps and wells in Franciscan melanges as far south as Briceland are related to one another and to offshore gas seeps in the Eel River basin west of Eureka. Ten onshore gas occurrences and two submarine seeps (at water depths of 520 m and 41 m) were sampled. Each onshore occurrence produces wet gas. The onshore occurrences are clearly related by similar hydrocarbon gas composition and, in most cases, by carbon isotopic composition of the hydrocarbon gases methane through butane. Methane carbon isotopic compositions ranged from -53 to -31 per mil.

Numerous seeps occur in the Cape Mendocino-Eel River basin areas, Point Arena, Point Reyes, San Mateo-Santa Cruz-Santa Clara counties, western San Joaquin Valley, the coastal and mountainous areas of Santa Barbara-Ventura counties, and in the Los Angeles basin (the Rancho La Brea Tar Pit being a famous example). Many natural gas seeps occur with active springs throughout the Coast Ranges. These oil and gas seeps generally occur in the western and southern portion of California where tectonic activity has uplifted petroleum carrier beds and reservoir rocks which are then breached by erosion. On the basis of available thermal maturity data, these oil and gas seeps generally occur in thermally immature host rock.

We have performed measurements of bulk conductivity as a function of temperature of an Fo (sub 80) -basalt partial melt between 684 degrees and 1244 degrees C at controlled oxygen fugacity. Melt fraction and composition variations with temperature calculated using MELTS [Ghiorso and Sack, 1995] indicate that the effect on melt conductivity of changing melt composition is balanced by changes in temperature (T). Thus bulk conductivity as a function of T or melt fraction in this system can be calculated assuming a constant melt conductivity. The bulk conductivity is well modeled by simple parallel calculations, by the Hashin-Shtrikman upper bound, or by Archie's law (sigma (sub partial) (sub melt) /sigma (sub melt) = C (sub 1) X (sub m) (super n) ). We estimate apparent values of the Archie's law parameters between 1150 degrees and 1244 degrees C as C (sub 1) = 0.73 + or - 0.02 and n = 0.98 + or -0.01. Estimates of the permeability of the system are obtained by using an electrical conductivity-critical scale length relationship and range from approximately 10 (super -14) to 10 (super -18) m (super 2) , comparing favorably with previously published values.

The authors employ two CRAY supercomputers for different parts of the decoupled calculation: the flow field is computed on the T3D massively parallel computer, and the contaminant migration is simulated on the C90 vector supercomputer. The authors compare simulation results for subsurface models based on homogeneous and heterogeneous conceptual models and find that the heterogeneities have a profound impact on the character of contaminant migration.

Forty-eight to seventy-two hours prior to surgery, subjects received a 70-84 [mgr]g dose of super(14)C. Urine and blood were analyzed by HPLC for PhIP and PhIP metabolites. Metabolites were identified based on HPLC co-elution with authentic PhIP metabolite standards, mass spectral analysis and susceptibility to enzymatic cleavage. In two subjects, 90% of the administered [ super(14)CPhIP dose was eliminated in the urine, whereas in the other, only 50% of the dose was found in the urine. One subject excreted three times more radioactivity in the first 4 h than did the others. Twelve radioactive peaks associated with PhIP were detected in the urine samples. The relative amount of each metabolite varied by subject, and the amounts of each metabolite within subjects changed over time. In all three subjects the most abundant urinary metabolite was identified as 2-hydroxyamino-1-methyl-6-phenylimidazo[4,5-b]pyridine- N super(2)-glucuronide (N-hydroxy-PhIP-N super(2)-glucuronide, accounting for 47-60% of the recovered counts in 24 h. PhIP accounted for <1% of the excreted radiolabel in all three patients. Other metabolites detected in the urine at significant amounts were 4-(2-amino-1-methylimidazo[4,5-b]pyrid-6-yl)phenyl sulfate, N-hydroxy-PhIP-N super(3)-glucuronide and PhIP-N super(2)-glucuronide. In the plasma, N-hydroxy-PhIP-N super(2)-glucuronide accounted for 60, 18 and 20% of the recovered plasma radioactivity at 1 h post PhIP dose in subjects 1, 2 and 3 respectively. Plasma PhIP was 56-17% of the recovered dose at 1 h post exposure. The relatively high concentration of N-hydroxy-PhIP-N super(2)-glucuronide and the fact that it is an indicator of bioactivation make this metabolite a potential biomarker for PhIP exposure and activation. Determining the relative differences in PhIP metabolites among individuals will indicate metabolic differences that may predict individual susceptibility to carcinogenic risk from this suspected dietary carcinogen.

AN - 69638222; 10082924 AB - In this paper, we present data on chromosome aberration frequencies in mice which served as unexposed controls in a variety of radiation and chemical toxicology experiments conducted in our laboratory in recent years. All chromosome aberration data were obtained by chromosome painting. In peripheral blood lymphocytes from 102 animals, the frequencies of translocations and insertions increased significantly with age. No increase with age was seen for dicentrics or acentric fragments. When the data were analyzed by strain, the age-related increase in translocation frequencies was observed only in the 71 homozygous C57BL/6 mice and not in any of the three heterozygous strains. Very few aberrations of any type were observed in 62 bone marrow samples, and no effect of age was seen for any aberration type in this tissue. These results are similar to those observed in unexposed humans, and suggest that the increase in translocations is not the result of accumulated damage from chronic 'background' environmental exposures but instead may be due to biological processes associated with aging.

However, the time between recorded frames can include several glottal cycles. Thus, only disorders that persist for many tens of cycles can be distinguished. To observe more transient events, a higher frame rate is needed. Highspeed digital cameras provide such an option. These cameras offer good resolution, easy operation, & very fast frame rates (up to 12000 fps) that allow for capture of transitory events, such as onsets & offsets of voicing & the details of a single vibratory cycle. These attributes can prove useful to voice clinicians & researchers alike. Here, the use of such cameras with & without image intensifiers is examined in a clinical & research setting & recommendations are offered for their operation, including the synchronization of the frame information with audio or other data. Specific information is offered on the Kodak EktaPro Hi-Spec Motion Analyzer Model 1012 with Intensified lmager Model VSG. 7 Figures, 2 References.

AN - 69275693; 10552422 AB - Mixtures of amino acids, creatine, and glucose simulating the composition of six different kinds of meats (beef, chicken breast, chicken thigh, turkey breast, pork, and fish) were dry-heated to simulate the formation of heterocyclic amines in meats. The presence of 16 heterocyclic amines was investigated in the model systems and in the six meats and their corresponding meat drippings to determine the importance of meat composition to heterocyclic amine formation. Nine mutagenic amines (IQ, MeIQ, 8-MeIQx, 4,8-DiMeIQx, PhIP, IQx, IFP, DMIP, and TMIP) were found to be present at concentrations >0.1 ng/g in some of the model systems and in some of the meats or pan residues. Heterocyclic amine concentrations clearly are affected by precursor composition in this model system, and the same nine heterocyclic amines formed in the meat and in the model system show that this is a well-controlled surrogate for the reaction conditions that occur in meats during cooking.

The carbon reservoir effect purported to exist in Quaternary lacustrine sediments of the McMurdo Dry Valleys was investigated by studying (super 14) C distribution, and testing alternate dating techniques. Our results show that the carbon reservoir effect is not pervasive. Stream and near-shore microbial mats and dissolved inorganic carbon (DIC) in the surface waters of Lake Fryxell are in equilibrium with modern (super 14) CO (sub 2) . The surface waters of Lake Hoare and Lake Bonney, however, have DIC (super 14) C ages of 1650 and 2080 yr B.P., respectively. These older age estimates are suggested to be due to the direct input of large amounts of glacial melt with relict DIC. On the other hand, Lake Fryxell receives only a minor component of its inflow directly from a glacier, while a large component must travel long distances in numerous shallow ephemeral streams after leaving local valley glaciers. This mode of melt-water input allows the water to equilibrate with modern CO (sub 2) before entering the lake. Bottom-water (super 14) C ages for Lake Hoare closely match surface sediment ages, supporting the widely published period approximately 1200 yr B.P. (after a 1650 yr reservoir correction) when most dry valley lakes apparently evaporated to small brine ponds and/or disappeared completely. Lake Bonney bottom-water is approximately 8000 yr B.P. Carbon dating is shown to be a viable technique for lake edge deposits, and possibly lake bottom deposits where a correction to the sediment surface age can be obtained. However, we conclude that deep-water paleolake deposits can not be reliably dated using (super 14) C alone because of an inability to determine the age of the reservoir correction (i.e. accounting for the initial carbon reservoir, plus the age of the bottom water). A suite of alternative and complimentary dating techniques were tested on modern and late Holocene lacustrine deposits. These include thermoluminescence (TL), (super 210) Pb, (super 137) Cs, and paleomagnetism. Of these techniques, TL (or the more sensitive optically stimulated luminescence) holds the most promise for correcting lake sediment (super 14) C ages. TL dating of the modern Lake Hoare sediments showed an approximately 1000 yr relict signal. This signal is unaffected by the age of the lake water. Both (super 210) Pb and (super 137) Cs occurred in very low levels in the sediments and do not appear to be viable dating techniques for the perennially ice-covered lakes of the McMurdo Dry Valleys. Paleomagnetism was not suited to the coarse-grained nature of Lake Hoare bottom sediments, but could be a useful alternative given a finer sediment type.

Four of these (sarcopside, graftonite, johnsomervilleite, and galileiite) constitute the majority of occurrences. The IIIB iron meteorites are confined to occurrences of only these four phosphates. The IIIA iron meteorites may contain one or more of these four phases; they may also contain other rarer phosphates, and silica (in two instances) and a silicate rock (in one instance). Thus, the IIIA lithophile chemistry is more varied than that of the IIB meteorites. Based on petrographic relations, sarcopside appears to be the first phosphate to form. Graftonite is probably formed by recrystallization of sarcopside. Johnsomervilleite and galileiite exsolved as enclaves in sarcopside or graftonite at lower temperatures, although some of these also nucleated as separate crystals. The IIIAB phosphates are carriers of a group of incompatible lithophile elements: Fe, Mn, Na, Ca, and K, and, rarely, Mg as well as Pb. These elements (and O) were concentrated in a residual, S-rich liquid during igneous fractional crystallization of the IIIAB core mass. The phosphates formed by oxidation of P as the core solidified and excluded O, which increased its partial pressure in the residual liquid. The trace siderophile trends in bulk IIIAB metal are paralleled by a mineralogical trend of the phosphate minerals that formed. For IIIAB meteorites with low-Ir contents in the metal, the phosphates are mainly Fe-Mn phases; at intermediate Ir values, more Na-bearing phosphates appear; at the highest Ir values, the rarer Na-, K-, Mg-, Cr-, and Pb- bearing phosphates appear. The absence of significant amounts of Mg, Si, Al, and Ti suggest depletion of these elements in the core by the overlying mantle.

Also presented is a generalization of a proven electrical resistance tomography (ERT) algorithm, to account for electrical impedance. Three methods are used to reconstruct electrical impedance data and their results compared. The first two methods employ approximate relationships between the measurements and reconstructed tomograph while the third approach employs fully complex algebra to account for the real and imaginary components of electrical impedance data. The electrical impedance tomography (EIT) and the perturbation analysis (PA) algorithms provided useful magnitude and phase images for the frequency range of 0.0625 to 64 Hz; images for 256 and 1024 Hz are also presented but these were not reliable. The frequency effect (FE) approach did not produce reliable phase images. Comparisons of the ERT and EIT magnitude images show that both methods provided equivalent results for the water blank, copper rod and PVC rod targets. The EIT magnitude images showed better spatial resolution for the sand-lead mixture target. Phase images from both methods located reasonably well anomalies of both high and low contrast induced polarization (IP) and provided better spatial resolution than the magnitude images. When IP was absent from the data, the EIT and PA algorithms reconstructed phase values consistent with the data noise levels.

As part of an on-going project with the goal of improving underground imaging, we are developing rock physics theories for relating elastic wave velocities to soil composition and fluid-flow parameters. Here we use effective medium theories to estimate velocities of unconsolidated sand-peat moss mixtures and compare the estimates to measured compressional and shear velocities from low-pressure laboratory experiments. We found that a self-consistent effective medium theory model using sand and porous peat as the constituents provides estimated velocities that are in good agreement with measured velocities.

We have used the finite-difference frequency-domain formulation of Beilenhoff et al. (1992) and the anisotropic PML (perfectly matched layer) approach (Berenger, 1994) to specify boundary conditions following Wu et al. (1997). PML deals with the fact that the computations must be done in a finite domain even though the real problem is effectively of infinite extent. The resulting formulas for the forward solver reduce to a problem of the form Ax = y, where A is a non-Hermitian matrix with real values off the diagonal and complex values along its diagonal. The matrix A may be either symmetric or nonsymmetric depending on details of the boundary conditions chosen (i.e., the particular PML used in the application). The basic equation must be solved for the vector x (which represents field quantities such as electric and magnetic fields) with the vector y determined by the boundary conditions and transmitter location. Of the many forward solvers that could be used for this system, relatively few have been thoroughly tested for the type of matrix encountered in our problem. Our studies of the stability characteristics of the Bi-CG algorithm raised questions about its reliability and uniform accuracy for this application. We have found the stability characteristics of Bi-CGSTAB [an alternative developed by van der Vorst (1992) for such problems] to be entirely adequate for our application, whereas the standard Bi-CG was quite inadequate. We have also done extensive validation of our code using semianalytical results as well as other codes. The new code is written in Fortran 90 and is designed to be easily parallelized, but we have not yet tested this feature of the code. An adjoint method is being developed for solving the inverse problem for conductivity imaging (for mapping underground plumes), and this approach, when ready, will make repeated use of the current forward modeling code.

Recent research indicates that many common contaminants can be destroyed in situ by hydrous pyrolysis/oxidation (HPO), eliminating the need for costly surface treatment and disposal. Steam injection, combined with supplemental air, can create the conditions in which HPO occurs. Field testing of this process, conducted in the summer of 1997, indicates rapid destruction of polycyclic aromatic hydrocarbons (PAHs). Previous work established a suite of underground geophysical imaging techniques capable of providing sufficient knowledge of the physical changes in the subsurface during thermal treatment at sufficient frequencies to be used to monitor and guide the heating and extraction processes. In this field test, electrical resistance tomography (ERT) and temperature measurements provided the primary information regarding the temporal and spatial distribution of the heated zones. Verifying the in situ chemical destruction posed new challenges. We developed field methods for sampling and analyzing hot water for contaminants, oxygen, intermediates and products of reaction. Since the addition of air or oxygen to the contaminated region is a critical aspect of HPO, noble gas tracers were used to identify fluids from different sources. The combination of physical monitoring with noble gas identification of the native and injected fluids and accurate fluid sampling resulted in an excellent temporal and spatial evaluation of the subsurface processes, from which the amount of in situ destruction occurring in the treated region could be quantified. The experimental field results constrain the destruction rates throughout the site, and enable site management to make accurate estimates of total in situ destruction based on the recovered carbon. As of October, 1998, over 400,000 kg (900,000 lb) of contaminant have been removed from the site; about 18% of this has been destroyed in situ.

Data were collected four times starting in July and ending in early September, 1998. ERT baseline images show a resistivity structure which is consistent with the known lithology in the rear part of the test block. There appears to be a low resistivity region in the front half of the block, particularly near the bottom. Difference images from August 19 and September 9 show clear and consistent resistivity decreases in the region near injection holes 18, 20, and 21 which can be associated with the injection of conductive water. The images show very little effect in the region around the other injection holes, 23, and 24 through 27 where far less water was injected. Difference images from August 19 and September 9 show resistivity decreases which could be interpreted as water moving down into the block. This is the same region which has an anomalously low resistivity in the baseline image. These results should be considered preliminary, and are subject to further interpretation.

Earlier work had been done at the same site by Wilt et al. (1996). This site is an interesting test for techniques under development for environmental engineering, because it can be viewed as an excellent analog of a shallow environmental remediation using steam injection. Surface magnetic field data (vertical and radial fields, magnitude and phase) were collected using 18 receiver stations along two profiles which ran radially from the EM transmitter well from 5 m to 120 m. The data at each surface station were collected while the EM transmitter was raised slowly from a depth of 120 m to a final depth of 20 m. As part of this experiment, a calibration of the EM transmitter was also performed. Magnetic field data from Lost Hills were successfully collected, including both vertical and horizontal (surface radial) magnitude and phase data along a northerly profile and along a westerly profile. We have observed that the radial receiver data appear to be better behaved than the vertical receiver data, suggesting that these data may be less sensitive to environmental clutter (numerous metallic pipes crisscrossing the site at the surface) than are the vertical data. Some simple 1-D modeling has been done to confirm that the expected conductivity change in the steam zone should produce an observable anomaly in the measured data when comparing the pre-steam to the post-steam conditions. Results of this test were positive. Further analyses of these data making use of a new code developed in a companion paper are in progress and will presented separately.

The VSP method consisted of using a multilevel hydrophone array giving 48 channels of recorded seismic data per shot. Hydrophone spacing was 0.5 m, with anti-tubewave baffling devices inserted between each phone, and at each end of the array to slow down and attenuate tube wave noise contaminating the desired data signals. The seismic source consisted of an impact weight-drop machine. The VSP data was processed, and inverted to produce 2D p-wave interval velocity sections with up to 0.5 m of vertical resolution in the unconsolidated sediments below the water table. Multiple 2D velocity sections were created, corresponding to radial arms of walk-away shot point records from multiple wells. These 2D velocity sections were then visually projected into the 3D survey volume, together with well locations, predefined hydrostratigraphic unit (HSU) layer boundaries, and the interpreted isopach map of a major HSU of interest. The interactive graphical display of all these data in 3D allowed correlations to be made between the VSP velocity images and the pre-existing data. The discovery of several low velocity zones below the water table was attributed to partially saturated pore spaces. Two thin (less than 1 m thick) layers with p-wave velocities as low as 500 m/s appeared to be perched on top of major aquifers undergoing pump extraction and treatment. Gas analysis from water samples taken from one of the aquifers indicated normal atmospheric air as a probable gas source. High pumping flow rates (20 to 30 gal/min) may help to explain how venturi action could be responsible for the intake of air from the vadose zone into porous but less permeable silty-sand units overlying sand-gravel aquifers. Possible uses for this VSP technique would be to delineate the zone of pumping influence, and help in the choice of suitable new well locations for either pumping or monitoring.

Measurements include frequency-dependent electrical properties using the four-electrode technique (10 mHz to 1 MHz), permeability, porosity, and acoustic velocities. We mixed clean Ottawa (quartz) sand with Na-montmorillonite (Wyoming bentonite) in a number of different configurations containing 0 to 10% clay: as a dispersed mixture, as discrete clay clusters, and arranged in distinct layers. Solutions of CaCl (sub 2) ranging from 0.0005 N to 0.75 N (0.05 to 64 mS/cm) and deionized water were used as saturating fluids. We found the electrical properties to be dependent on clay content, fluid conductivity, and microstructure in a complex fashion. Increasing fluid conductivity and increasing clay content generally resulted in higher electrical conductivity. For an individual sample, two main regions of conduction exist: a region dominated by surface conduction and a region where the ionic strength of the saturating fluid controlled conduction. The sample geometry (dispersed, nondispersed, or layered clay configuration) was found to greatly affect the magnitude of the surface conductance in the range of low fluid conductivity.

Geostatistical methods are used to characterize the spatial variability of geologic facies that control subsurface variability of permeability and electrical resistivity. Synthetic ERT data sets are generated from geostatistical realizations of alluvial facies architecture.

Three methods are used to invert electrical impedance data and their tomographs compared. The first method uses an electrical resistance tomography (ERT) algorithm (designed for DC resistivity inversion) to perform impedance magnitude inversion and a linearized perturbation approach (PA) to invert the imaginary part. The second approximate method compares ERT magnitude inversions at two frequencies and uses the frequency effect (FE) to compute phase tomographs. The third approach, electrical impedance tomography (EIT), employs fully complex algebra to account for the real and imaginary components of electrical impedance data. The EIT approach provided useful magnitude and phase images for the frequency range of 0.0625 to 64 Hz; images for higher frequencies were not reliable. Comparisons of the ERT and EIT magnitude images show that both methods provided equivalent results for the water blank, copper rod and PVC rod targets. The EIT magnitude images showed better spatial resolution for a sand-lead mixture target. Phase images located anomalies of both high and low contrast IP and provided better spatial resolution than the magnitude images. When IP was absent from the data, the EIT algorithm reconstructed phase values consistent with the data noise levels.

ERT was also used to monitor the water flood of a thin-wall grout barrier to verify its hydraulic integrity. Both case studies were done by comparing images of electrical resistivity before and after a change was induced in the subsurface. Barrier materials or flood water were imaged as anomalies which were more electrically conducting than the native sandy soils at the test sites. Although the spatial resolution of the ERT was not sufficient to resolve flaws in the barrier under construction smaller than a reconstruction voxel (50 cm on a side), the images did show the spatial extent of the barrier materials and therefore the general shape of the structure.

Porosity, composition (clay content), and fluid content and identification are of particular interest. The ultrasonic (100-500 kHz) pulse transmission technique was used to collect data for highly attenuating materials appropriate to the vadose zone. Up to several meters of overburden was simulated by applying low uniaxial stress of 0.1 MPa to the sample. The approach has been to make baseline measurements for pure quartz sand, because the elastic properties are relatively well known except at the lowest pressures. Second phases are then added to modify the sample microstructure and ultrasonic measurements are made to characterize the effect of the admixed second phase. Samples are fabricated from Ottawa sand mixed with a swelling clay (Wyoming bentonite), and with a common organic soil amendment, peat. Compressional (P) velocities are low, ranging from 169 to 360 m/s for the mixtures at low stress. Shear (S) velocities are about half of the compressional velocity, but show different sensitivity to microstructure. Adding clay increases the shear amplitude dramatically with respect to P, and also changes the sensitivity of the velocities to load. These experiments demonstrate that P and S velocities are sensitive to the amount and type of admixed second phase, even at low concentrations. Other properties of the transmitted signals which include the ratio of S and P amplitudes, velocity gradient with depth, and the frequency content of transmitted pulses, provide additional information and are not now used in near-surface surveys.

Based on the radionuclide concentrations and the noble gas signatures we conclude the 26 H-chondrite samples represent at least 13 different falls. The exposure ages of most H-chondrites are in the range of 4-10 million years (My). This age range encompasses the well-established exposure age peak at approximately 7 My and an additional feature at approximately 4 My. We determined the terrestrial ages on the basis of the (super 36) Cl concentration as well as using the relation between the (super 36) Cl/ (super 10) Be ratio and the (super 10) Be concentration. This relation also corrects for shielding effects and reduces the uncertainty in the age by approximately 25% compared to simple (super 36) Cl terrestrial ages. About 40% of the meteorites are older than 100 thousand years (ky), but none are older than 200 ky. The relatively short terrestrial ages suggest that Frontier Mountain is a young meteorite stranding area. This seems to be supported by the bedrock exposure history, which shows a recent surface exposure < or =70 ky.

Thirty-five computer users used the adjustable split design keyboard for 7-14 days during their usual work and were instructed to adjust the keyboard to the opening angle they preferred. At the end of this period, three-dimensional motion analysis was performed to compare the distribution of wrist joint angles while subjects typed on a conventional keyboard and the adjustable keyboard adjusted to the subject's preferred angle. The mean preferred opening angle was 14 degree plus or minus 10. The mean ulnar deviation of the subjects who selected the opening angles between 21 and 28 degree (n = 12) decreased from 18 degree plus or minus 5 on the flat to 14 degree plus or minus 5 on the adjustable (p < 0.05), while those who selected 0 to 10 degree (n = 6) and 11 to 20 degree (n = 17) split angles showed no significant differences in ulnar deviation. Mean wrist extension on the adjustable keyboard was 17 degree plus or minus 5 and was significantly less than the 24 degree plus or minus 5 observed on the conventional keyboard and most likely due to the presence of palm support. On average, subjects reported that the adjustable keyboard was more comfortable (0.5 plus or minus 0.5) (worse = -1, same = 0, better, = 1) in comparison with the conventional keyboard.

AN - 69563345; 9935154 AB - [2-14C]2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) was administered orally (304 ng/kg body-weight dose based upon an average 70-kg-body-weight subject) to 5 human colon-cancer patients (58 to 84 years old), as well as to F344 rats and B6C3F1 mice. Colon tissue was collected from the human subjects at surgery and from the rodents 3.5 to 6 hr after administration. Colon DNA-adduct levels and tissue available doses were measured by accelerator mass spectrometry (AMS). The mean levels of MeIQx in the histologically normal colon tissue were not different among the human (97 +/- 26 pg MeIQx/g), rat (133 +/- 15 pg/g) or mouse (78 +/- 10 pg/g) tissues; and no difference existed between the levels detected in human normal and tumor tissue (101 +/- 15 pg/g). Mean DNA-adduct levels in normal human colon (26 +/- 4 adducts/10(12) nucleotides) were significantly greater (p < 0.01) than in rats (17.1 +/- 1 adduct/10(12) nucleotides) or mice (20.6 +/- 0.9 adduct/10(12) nucleotides). No difference existed in adduct levels between normal and tumor tissue in humans. These results show that MeIQx forms DNA adducts in human colon at low dose, and that the human colon may be more sensitive to the effects of MeIQx than that of mice or rats.

AN - 69593496; 10029687 AB - This study was conducted to determine whether the frequency of hypoxanthine phosphoribosyltransferase (HPRT) deficient lymphocyte mutants would detect an effect of radiation exposure in a population of Russians who were exposed to low levels of radiation while working in 1986 and 1987 as liquidators cleaning up after the Chernobyl nuclear power reactor accident. The HPRT lymphocyte cloning assay was performed on peripheral blood lymphocytes collected between 1992 and 1996 from 142 liquidators and 66 Russian controls, and between 1989 and 1993 from 231 American controls. Russian and American controls were not significantly different for either cloning efficiency or mutant frequency (MF); inclusion of both sets of controls in the analysis increased the ability to detect a Chernobyl exposure effect in the liquidators. After adjusting for age and smoking, the results revealed no significant difference in cloning efficiency of Chernobyl liquidators relative to Russian controls but a significant, 24% increase in liquidator HPRT mutant frequency over Russian controls (90% confidence interval was 7% to 45% increase). The analytical method also accounted for differences in precision of the individual estimates of log CE and log MF and accommodated for outliers. The increase in HPRT mutant frequency of liquidators is an attribute of the exposed population as a whole rather than of individuals. These results demonstrate that, under appropriate circumstances, the HPRT specific locus mutation assay of peripheral blood lymphocytes can be used to detect a semi-acute, low dose radiation exposure of a population, even 6 to 10 years after the exposure.

Conversely, if the depth of soil varies across an actively eroding landscape, then rates of soil production will also vary and, consequently the landscape will not be in morphologic equilibrium. The slow evolution of hillslopes relative to the tempo of climatic variations and tectonic adjustments would suggest that local morphologic disequilibrium may be expected in many landscapes. Here, we explore this issue of equilibrium landscapes through a previously developed model that predicts the spatial variation in thickness of soil as a consequence of the local balance between soil production and erosion. First, we confirm the assumption in the model that soil production varies inversely with the thickness of soil using two independent methods. One method uses the theoretical prediction that at local steady state (soil production equals removal), the depth of soil should vary inversely with hillslope curvature. The second method relies on direct measurements of in situ produced concentrations of cosmogenic (super 10) Be and (super 26) Al in bedrock at the base of the soil column. For our study site in Northern California, the two methods agree and yield the expression that the rate of soil production declines exponentially with the thickness of soil from 0.077 mm/year with no soil mantle to 0.0077 mm/year under 1 m of soil. We then use this function of soil production in a coupled production and diffusive model of sediment transport to explore the controls on the spatial variation of the depth of soil on four separate spur ridges (noses) where we measured the data for the function of soil production. Model predictions are sensitive to boundary conditions, grid scale, and run time. Nonetheless, we found good agreement between predicted and observed depths of soil as long as we used the observed function of soil production. The four noses each have spatially varying curvature and, consequently, have varying depths of soil, implying morphologic disequilibrium. We suggest that our study site has been subjected to a wave of incision and varying intensities of erosion because of tectonic and climatic oscillations that have a frequency shorter than the morphologic response time of the landscape.

Using the ratio, (super 26) Al/ (super 10) Be, we calculate that striated outcrops of Sioux Quartzite in southwestern Minnesota (southern margin) were last overrun by ice at least 500,000 years ago. Weathered bedrock tors on the once-glaciated uplands of Baffin Island (northern margin) are eroding no faster than 1.1 m Myr (super -1) , the equivalent of at least 450,000 years of surface and near-surface exposure. Our data demonstrate that exposure ages and erosion rates calculated from single nuclides can underestimate surface stability dramatically because any intermittent burial, and the resultant lowering of nuclide production rates and nuclide abundances, will remain undetected.

Dating depositional surfaces like terraces that are older than the range of (super 14) C, however, is difficult. We employ a cosmogenic radionuclide (CRN) profile technique that addresses a major problem of CRN dating on such surfaces: nuclide inheritance. By measuring (super 10) Be and (super 26) Al profiles, we constrain the exposure age and the mean CRN inheritance for the deposit. The CRN profile also yields a self-check on the assumptions underlying the method. We report our attempts to date terraces along the Wind River, WY. Like many sequences of western North American fluvial terraces, these are inferred to reflect oscillation between glacial and interglacial conditions in the headwaters. Previous dating of some of these terraces and the associated terraces and glacial deposits makes this a unique location to compare dating methods. Dates from five sites along the Bull Lake-glacial correlative terrace (WR-3) are approximately 118-125 ka, which agrees with dates on Bull Lake-age moraines and independent age estimates on the terrace, and is consistent with the model of terrace-glacial relationship. CRN inheritance is significant and highly variable, requiring it be considered despite the additional sampling complexity. Assuming all inheritance in WR-3 deposits arises during exhumation in the headwaters, we obtain minimum mean rates of exhumation of approximately 13-130 m/My for the source rocks. Alternatively, assuming the CRNs are inherited during clast transport, the time of fluvial transport from source to terrace is > approximately 10 ka; it increases downstream and is lower for sand than cobbles. The CRN ages for older terraces (WR-7 = approximately 300 ka and WR-15 = approximately 510 ka) are lower by approximately 50% than previous estimates based on tephrochronology; the most plausible explanation is eolian deflation of a once thicker loess cover on the terrace surfaces. Mean thicknesses of loess of approximately 0.5-1.5 m are required to reconcile these concentrations of CRN with the previous estimates of age. Difficulty in dating the older terraces emphasizes that geologic caution, independent estimates of age, and multiple sample sites should still be part of dating depositional surfaces with CRNs, even when employing the inheritance-correction technique.

Melting depths are obtained from pressure-sensitive mineral-melt partition coefficients for Na, Ti, Hf, and the rare earth elements (REE). Melting depths are estimated by comparing model aggregate melt compositions to natural basalts from Hawaii and the East Pacific Rise (EPR). Variations in melting depths in a peridotite mantle are sufficient to yield observed differences in Na/Ti, Lu/Hf, and Sm/Yb between Hawaii and the EPR. Initial melting depths of 95-120 km are calculated for EPR basalts, while melting depths of 200-400 km are calculated for Hawaii, indicating a mantle that is 300 degrees C hotter at Hawaii. Some isotope ratios at Hawaii are correlated with Na/Ti, indicating vertical stratification to isotopic heterogeneity in the mantle; similar comparisons involving EPR lavas support a layered mantle model. Abundances of Na, Ti, and REE indicate that garnet pyroxenite and eclogite are unlikely source components at Hawaii and may be unnecessary at the EPR. The result that some geochemical features of oceanic lavas appear to require only minor variations in mantle mineral proportions (2% or less) may have important implications regarding the efficiency of mantle mixing. Heterogeneity required by isotopic studies might be accompanied by only subtle differences in bulk composition, and material that is recycled at subduction zones might not persist as mineralogically distinct mantle components.

The physical model was constructed to simulate most of the features of the numerical model used to calculate the large SEG/EAGE synthetic seismic data set. The physical model is slightly simplified, since it could not be constructed with the velocity gradients used in the numerical model. Two data sets were collected from the model, one a simulation of a traditional marine survey, the other a simulation of a survey with vertical arrays of receivers. The main reason for collecting the two data sets was to compare images obtained from the marine survey with those obtained from the vertical receiver arrays.

Measurements include frequency-dependent electrical properties using the four-electrode technique (10 mHz to 1 MHz), permeability, porosity, and acoustic velocities. We mixed clean quartz sand with Na-montmorillonite in a number of different configurations containing 0 to 10% clay: as a dispersed mixture, as discrete clay clusters, and arranged in distinct layers. Solutions of CaCl2 ranging from 0.0005 N to 0.75 N (0.05 to 64 mS/cm) and deionized water were used as saturating fluids. We found the electrical properties to be dependent on clay content, fluid conductivity, and microstructure in a complex fashion. Increasing fluid conductivity and increasing clay content generally resulted in higher electrical conductivity. For an individual sample, two main regions of conduction exist: a region dominated by surface conduction and a region where the ionic strength of the saturating fluid controlled conduction. The sample geometry (dispersed, non-dispersed, or layered clay configuration) was found to greatly affect the magnitude of the surface conductance in the range of low fluid conductivity.

Quantification of the effect of such steel casing on the induced field is the most significant limitation of the technique. Recent data acquired at a site in Richmond, California quantify the effect of steel casing on induction measurements and demonstrate this effect to be separable. This unique site contains adjacent steel and plastic wells in which frequency soundings demonstrate low spectrum (1.0 - 50 Hz) measurements an effective means of isolating the casing response from the formation response. It is also shown that the steel casing effect on the induction coil is highly localized, and limited to less than 0.30 meters above and below the coil.

Several features in the elastic modeling code implemented on a massive parallel computer have been enhanced for realistic simulation of elastic waves in large geological models. Based on a velocity model derived from horizon-based pre-stack depth migration velocity analysis, multi-component synthetic seismograms have been generated. The synthetics resemble the field observations in terms of the arrival times of many coherent events including strong converted waves and differential waveform characteristics exhibited in the vertical and horizontal components, respectively. Many of these coherent arrivals can be identified through observation of the time-lapse snapshots of the velocity/stress distribution in a grid volume. Comparison of the synthetic and observed VSP gathers reveals the effects of the complex subsurface media on elastic wave propagation.

In some cases, however, installing multiple downhole electrodes is too costly (e.g., deep targets) or risky (e.g., contaminated sites). For these cases we have examined the possibility of using the steel casings of existing boreholes as electrodes. The first case we investigated used an array of steel casings as electrodes. This results in very few data and thus requires additional constraints to limit the domain of possible inverse solutions. Simulations indicate that the spatial resolution and sensitivity are understandably low but it is possible to coarsely map the lateral extent of subsurface processes such as steam floods. A hybrid case uses traditional point electrode arrays combined with long-conductor electrodes (steel casings). Although this arrangement provides more data, in many cases it results in poor reconstructions of test targets.

AN - 69768418; 10335376 AB - Heterocyclic aromatic amines (HAA) and polycyclic aromatic hydrocarbons (PAH) are mutagens and animal carcinogens sometimes formed when foods are heated or processed. Determining their role in cancer etiology depends on comparing human exposures and determining any significant dose-related effects. Chemical analysis of foods shows that flame-grilling can form both PAH and HAA, and that frying forms predominantly HAA. With detection limits of about 0.1 ng/g, amounts found in commercially processed or restaurant foods range from 0.1 to 14 ng/g for HAA, and levels of PAH up to 1 ng/g in a liquid smoke flavoring. Laboratory fried samples have greater amounts of PAH, up to 38 ng/g in hamburgers, and high levels of HAA, over 300 ng/g, are measured in grilled chicken breast. Understanding the processing conditions that form PAH and HAA can lead to methods to greatly reduce their occurrence in processed foods.

AN - 69594072; 10037323 AB - A pair of multicolor FISH assays (X-Y-21 and A-M-16) was developed for human sperm to simultaneously measure sex ratios; aneuploidies involving chromosomes 1, 16, 21, X, and Y; meiotic diploidies; and structural aberrations involving chromosome 1p. Sex ratios in sperm were not significantly different from unity among healthy men. Baseline frequencies of disomic sperm for chromosomes 1, 8, and 21 were similar (6.7 per 10(4) sperm, 95% CI of 5.6-8.1), suggesting that among these three chromosomes, chromosome 21 was not especially prone to nondisjunction. Frequencies of disomy 16 sperm were significantly lower, however (3.5 per 10(4) sperm, 95% CI of 2.0-6.2; P < 0.02). The baseline frequencies of sperm disomy by FISH for chromosomes 16 and 21 were validated against aneuploidy data obtained by the hamster-egg technique for human sperm cytogenetics. The frequencies of X-X, Y-Y, X-Y ("Klinefelter") sperm and sex-null ("Turner") sperm were 5.5, 5.1, 5.5, and 7.8 per 10(4) sperm, respectively. For chromosomes 16 and 21, the frequencies of nullisomic and disomic sperm were similar, suggesting that gain and loss events occurred symmetrically. However, more gain than loss was reported for chromosomes 1, X, and Y. The frequency of MI and MII diploid sperm (with flagella) was approximately 12 per 10(4) (range 8.3-16.7 per 10(4) sperm). Based on flagella data, the frequency of somatic cells in the semen was estimated to be approximately 1.8 per 10(4) sperm. Loss or gain of a portion of chromosome-arm 1p occurred in 5.5 per 10(4) sperm, and the percentage of sperm carrying structural aberrations within the haploid genome as calculated from FISH (1.4%), was similar to that obtained with the hamster-egg technique. These complementary sperm FISH assays have promising applications in studies of chromosomally abnormal sperm after exposure to occupational, medical, and environmental toxicants.

AN - 69571462; 9973089 AB - In the present study, F ratios for both stable chromosome aberrations, i.e. ratios of translocations to pericentric inversions, and unstable aberrations, i.e. dicentrics and centric rings, were measured using fluorescence in situ hybridization. F ratios for stable aberrations measured after exposure to low (2.89 Gy 60Co gamma rays) and high-LET (0.25 Gy 56Fe ions; 1.25 Gy 56Fe ions; 3.0 Gy 12C ions) radiation were 6.5 +/- 1.5, 4.7 +/- 1.6, 9.3 +/- 2.5 and 10.4 +/- 3.0, respectively. F ratios for unstable aberrations measured after low (2.89 Gy 60Co gamma rays) and high-LET (0.25 Gy 56Fe ions; 3.0 Gy 12C ions) radiations were 6.5 +/- 1.6, 6.3 +/- 2.3 and 11.1 +/- 3.7, respectively. No significant difference between the F ratios for low- and high-LET radiation was found. Further tests on the models for calculation of the F ratio proposed by Brenner and Sachs (Radiat. Res. 140, 134-142, 1994) showed that the F ratio may not be straightforward as a practical fingerprint for densely ionizing radiation.

AN - 69243238; 10554178 AB - BACKGROUNDExposures to cadmium have been reported to reduce male fertility and there are several hypotheses that suggest how reduced male fertility may result from incorporation of cadmium into sperm chromatin. The purpose of this study was to determine whether mice subjected to long-term intraperitoneal cadmium exposure incorporated cadmium into their sperm chromatin.METHODSMale mice were exposed to 0.1 mg/kg body weight cadmium in the form of CdCl2 via intraperitoneal injection once per week for 4, 10, 26, and 52 weeks and then sacrificed. The cadmium contents of the liver, testes, pooled sperm, and pooled spermatids from dosed and control animals were determined by atomic absorption spectroscopy. Cadmium and zinc contents in individual sperm and spermatid heads were determined by particle-induced x-ray emission.RESULTSAtomic absorption spectroscopy revealed that although cadmium accumulated in the liver and testes, cadmium was not detected in pooled sperm or spermatid samples down to minimum detectable limits of 0.02 microg/g dry weight. Particle-induced x-ray emission analyses did not show the presence of cadmium in any sperm or spermatid head down to minimum detectable limits of 15 microg/g dry weight. Particle-induced x-ray emission analyses also demonstrated that phosphorus, sulfur, and zinc concentrations in individual sperm and spermatid heads were not altered by exposure to CdCl2.CONCLUSIONSBecause cadmium was not incorporated into sperm chromatin at levels above 0.02 microg/g dry weight, the data cast doubt on hypotheses that suggest that reduced male fertility may result from incorporation of cadmium into sperm chromatin.

The SVAT leads to general warming of the climate over continents in association with enhanced sensible heat fluxes. The wetness bias of AGCM is reduced drastically with reductions in latent heat fluxes and precipitation. There is reduction in cloudiness when the SVAT is coupled which results in increased solar radiation at the surface. Upward long wave radiation increases in association with increases in land surface temperature. Although the coupling of SVAT improves surface fluxes of heat and water vapor, these changes are mainly offset by changes in solar and infrared radiative fluxes. Global mean energy balance at the surface and the top of atmosphere is improved marginally.

The (super 240) Pu/ (super 239) Pu ratio of these samples indicates that an underground nuclear test 1.3 km N of the sample collection site was the origin of the Pu. The extent of radionuclide migration may thus have been significantly underestimated in previous models of radionuclide transport, and the implications for the containment of radwaste are discussed.

The required equipment is readily available from scientific equipment supply houses at minimal cost. Pollen samples from lake sediments required about 4 h of hand picking, whereas samples from marine sediments required about 8 h labor. Pollen dates from marine sediments were much older than expected. We are attempting to resolve whether this is due to contamination of the pollen or the presence of significant quantities of old reworked pollen. Pollen dates from lake sediments associated with Mazama Ash were consistent with other published ages; however, replicate dates on pollen samples from above the ash were consistently older than the surrounding sediment. Our results suggest that caution must be used when interpreting pollen dates if the potential for sediment reworking is present.

Geological and vegetation mapping are attempted through spectral classification of imagery. Particular hot spring areas in the caldera are targeted for analysis. The data is analyzed for unique geobotanical patterns in the vicinity of hot springs as well as gross identification of dominant plant and mineral species. Spectra used for the classifications come from a vegetation spectral library created for plant species found to be associated with geothermal processes. This library takes into account the seasonality of vegetation by including spectra for species on a monthly basis. Geological spectra are taken from JPL and USGS mineral libraries. Preliminary classifications of hot spring areas indicate some success in mineral identification and less successful vegetation species identification. The small spatial extent of individual plants demands either subpixel analysis or increased spatial resolution of imagery. Future work will also include preliminary analysis of a hyperspectral thermal imagery dataset and a multitemporal air photo dataset. The combination of these remotely sensed datasets for Long Valley will yield a valuable product for geothermal exploration efforts in other regions.

It includes both discontinuous and continuous Fe-Mg reactions; contours of Fe/(Fe + Mg) for continuous reactions define P-T vectors along which continuous melting will occur. For biotite-bearing assemblages (garnet + biotite + sillimanite + K-feldspar + liquid, and garnet + biotite + cordierite + K-feldspar + liquid), Fe/(Fe + Mg) contours have negative gradients; melting occurs with increasing T or P. For biotite-absent assemblages (garnet + cordierite + sillimanite + K-feldspar + liquid, and garnet + cordierite + orthopyroxene + K-feldspar + liquid), Fe/(Fe + Mg) contours have zero gradients; melting occurs only with increasing P. The grid predicts abundant matrix K-feldspar only if rocks are heated at 3.8 kbar, and generation of late biotite + sillimanite replacing garnet, cordierite, or as selvages around leucosomes, is only common in rocks in which melt is not removed. Also there is a predicted field for dehydration melting of staurolite at 5-12 kbar. Textures in migmatities from New Hampshire, USA, suggest that prograde dehydration melting reactions are very nearly completely reversible during cooling and crystallization in rocks in which melt is not removed. Therefore many reaction textures in 'low-grade' migmatites may represent retrograde rather than prograde reactions.

Without recharge, hydrodynamic pressures would eventually fall, and methane would desorb and be lost. Recharge is also thought to be responsible for sustaining convergent, upward flow of water on which other hydrodynamic elements of the trap are partially dependent. Our work suggests that the pervasive permeability (cleat) system necessary to sustain this type of hydraulic conductivity does not exist in the Fruitland Formation. Nor do we find evidence for the upward (cross-formational) flow that this model requires. Waters from wells in the Colorado portion of the basin show higher TDS and chloride concentrations closer to outcrop than should be expected if the proposed models are correct. Iodine ( (super 129) I) dating of waters indicates minimum ages of 4 mybp (Pleistocene) to 45 mybp (Eocene). Spatial distributions of these ages and water chemistry suggest significant barriers to down-dip water flow from the outcrop and appear to correlate with patterns in well performance. These data, interpreted in the context of available production data, indicate that at least some portions of the basin contain waters relatively unaffected by outcrop recharge.

The current plan for the disposal of the excess Pu is to incorporate it into a crystalline ceramic with a matrix composition described by the quaternary zirconolite/pyrochlore system: CaHfTi (sub 2) O (sub 7) - CaPuTi (sub 2) O (sub 7) - CaUTi (sub 2) O (sub 7) - Gd (sub 2) Ti (sub 2) O (sub 7) . An impurity phase found in this system is U-rich brannerite, UTi (sub 2) O (sub 6) , which is also commonly found in many uranium deposits as (U,Th,Ca,Y)(Ti,Fe) (sub 2) O (sub 6) . Pyrochlore is a common accessory mineral in many geologic settings and has a nominal stoichiometry, ABTi (sub 2) O (sub 7) , where A = Ca, REE and B = U, Th, REE, and can occur with a wide variety of substitutions on the A and B sites. In order to develop a useful model for the thermodynamic stability of these complex solid solutions, it is necessary to determine the energetics of the end-member phases. High temperature oxide melt solution calorimetry was used to characterize the energetics of CaMTi (sub 2) O (sub 7) -pyrochlore where M = Hf, Zr, Ce; a Gd-substituted pyrochlore, Gd (sub 2) Ti (sub 2) O (sub 7) ; and MTi (sub 2) O (sub 6) - brannerite where M = Ce, Th. The enthalpies of formation from the binary oxides at 298.15 K were calculated (kJ per mole, errors are reported as 2 standard deviaitons of the mean in parentheses): CaHfTi (sub 2) O (sub 7) = -111.2(4.3), CaZrTi (sub 2) O (sub 7) = -88.7(4.0), CaCeTi (sub 2) O (sub 7) = +67.9(25.7), Gd (sub 2) Ti (sub 2) O (sub 7) = -113.0(5.0), CeTi (sub 2) O (sub 6) = +113.3(3.1) and ThTi (sub 2) O (sub 6) = +18.3(1.6). Solution calorimetry of uranium pyrochlore, CaUTi (sub 2) O (sub 7) and uranium brannerite, UTi (sub 2) O (sub 6) is underway. Data for their formation enthalpies will be presented. The enthalpy of formation of the brannerites becomes more exothermic with increasing tetravalent cation radius, that of the pyrochlores becomes more endothermic.

The craters are usually sharply defined, show a distinct central mound, and are surrounded by radial fractures. Vertical sections show prominent conical fracturing, and a bright halo zone below the crater floors. Thin sections exhibit distinct open (tensile) fractures below the crater floor, and zones adjacent to the craters where 100% of the quartz grains show well-developed planar features. On the other hand, thin sections of the contact zones lack evidence of any dissolution processes. Thus, we reject the pressure dissolution model and favor dynamical deformation by shock from the nearby Azuara impact structure and its possible Rubielos de la Cerida twin crater (mid-Tertiary? age). Accordingly, the cratering in the conglomerates is explained by shock acceleration of the cobbles combined with rarefaction, spallation, and reverberation processes. The shock cratering of the quartzite cobbles is associated with intense subparallel macroscopic and microscopic fracturing in the conglomerates that shows radial and/or tangential orientation with respect to the centers of Azuara and proposed Rubielos structures. The closely spaced intergranular microfractures are decorated with fresh-water fluid inclusions, which have hydrothermal trapping temperatures of about 200 degrees C. This type of deformation has now been simulated in shock experiments on artificial conglomerates, confirming the impact model. We suggest that these deformations may be typical in shocked autochthonous conglomerates, and that they may provide a signature of impacts in cases where shock metamorphism is weak or absent.

There is a need to reconstruct the magnitude and frequency of past climatic change in this region to understand and model the dynamics of the main climatic systems that operate today in Central Asia and for testing general circulation models that are used to predict future global and regional environmental change. However, the timing of glaciation in these regions is poorly constrained. This is partially due to the lack of organic material within sediments in these high altitude environments which therefore inhibits the use of radiocarbon dating. During the last few years, however, we have been able to make improved reconstructions of the former extent and timing of glaciation in the Himalayas using detailed mapping, and optically stimulated luminescence and cosmogenic dating. Our results show that in the Karakoram Mountains of northern Pakistan, preliminary cosmogenic dating constrains four glaciations at approximately 50-60 ka, approximately 22-25 ka, approximately 16-18 ka and approximately 10-12 ka. Further south in the middle Indus valley and Swat Himalaya OSL dates constrain glaciations at approximately 77 ka, approximately 38 ka, approximately 27 ka, approximately 21-23 and approximately 15 ka. In northern India cosmogenic dating provides evidence for glacial advances at approximately 10 ka and approximately 14 ka. In the Khumbu Himal, OSL dating constrains two advances at approximately 10 ka and at approximately 18-25 ka. These data show that multiple glaciations have occurred throughout the Himalayas during the last glacial cycle, and that glaciation was regionally asynchronous. Furthermore, the maximum extent of glaciation occurred earlier than the northern hemisphere last glacial maximum (LGM: approximately 18-22 ka) when the northern hemisphere ice sheets reached their maximum.

Of particular interest are effects of heterogeneities on flow and transport under unsaturated and partially saturated conditions, migration behavior of colloids in fractured and unfractured tuff and the effect of scaling (lab scale to field scale and then to site scale). Implementation of the test requires determining the movement of radionuclide surrogates tracers in a closely-monitored infiltration experiment using a large, in situ, 10 mX10 mX7 m tuff block. Several geophysical methods are used to monitor tracer position as a function of time: 1- Electrical resistance tomography (ERT) provides 3D images of electrical resisitvity at approximately one month intervals. Of course, introduction of the tracer into the rock mass changes the electrical resistivity, therefore the ERT images are interpreted in terms of moisture content changes relative to a background, pretest condition. In addition, however, pre-experiment, baseline images have helped to delineate heterogeneity in the test block. 2- Cross borehole radar tomography provides 2D images of electromagnetic permitivity in four planes. These images can also be interpreted in terms of moisture content changes. As a result of the 200 MHz operating frequency, this method provides particularly high resolution images. 3- Borehole neutron logging provides 1D data of moisture content along several boreholes. This method provides the highest spatial resolution data but with limited spatial coverage. Taken together, these data provide valuable insight into the actual flow and transport during the test and make it possible to extend the limited information available from the post experiment coring.

Analysis of aquifer (channel) connectivity, simulation of complex response to a pumping test, assessment of effective hydraulic conductivity, and transport analysis provokes a "connected network" paradigm for the system and suggests potential shortcomings of more conventional paradigms of subsurface heterogeneity. Owing to mathematical expediency, most previous models of complex heterogeneity (e.g., Gaussian random field models) have focused on aquifer units, thereby neglecting potentially critical processes occurring in aquitard units. This evolution of assumptions and paradigms closely parallels the history of pumping-test model development, which initially emphasized simplified, homogeneous models (e.g., Theis equation), but were gradually improved to include aquitard materials as well (e.g., leaky aquifer theory). In typically heterogeneous formations, aquitard materials comprise 50-percent or more of the system. Simulation of complex response to a 24-hr pumping test demonstrated plausibility of the connected network paradigm while providing insights into hydraulic processes. Simulated time-drawdown responses at observation well locations were most sensitive to hydraulic properties of the aquitard materials. Contrary to conventional leaky aquifer paradigms, decreasing K of the aquitard (floodplain) facies increased, rather than decreased, drawdowns at observation points located in aquifer zones that would appear to be separate from the channel stratum being pumped. Because of the extensive connectivity of channel sediments effective hydraulic conductivity parallel to the channels (dip direction) is merely the arithmetic mean. K in strike and vertical directions are both controlled by more complex hydraulics due to circuitous connectivity transverse to the channel orientations. Channel connectivity and vertical K are sensitive to spatial cross correlation between channel and levee facies in the geostatistical spatial model, demonstrating that facies juxtapositional tendencies can be hydrologically significant. High-resolution transport simulations further illustrate the network paradigm and demonstrate the negative consequences of characterizing only the aquifers and neglecting the aquitards.

There are two uncertainties associated with them: 1) surface processes that control the overall growth rate; 2) dependence of growth mechanism upon supersaturation. We compare experimental evidence with fundamental growth theories to show where popular affinity-based rate expressions hold or break down. Using in situ Atomic Force Microscopy (AFM), we conducted calcite growth experiments to determine (1) the supersaturation (s) range where growth occurs only by spiral formation; (2) the critical supersaturation that initiates a surface nucleation mechanism; (3) step velocities, Vs, and the slopes of growth hillocks, p; (4) normal growth rates, Rm, for single spirals; and (5) dependence of Rm upon dislocation source structure. We find that, at lower values of s (0 to 0.8), growth is initiated solely by surface imperfections including screw dislocations. Thus, crystal defect-originated growth, in particular, spiral growth, is the manifested mechanism. When s >0.8, 2-D nucleation becomes increasingly important. Measurements of Rm for {104} faces grown by single spirals indicate a superlinear dependence of Rm upon chemical affinity. AFM observations demonstrate that growth kinetics is controlled by dislocation source structures in addition to supersaturation and the dominant growth mode is hillock formation initiated at complex dislocation sources. General surface process-based rate expressions were derived by analyzing the dependence of p upon dislocation source structures to reveal a complex relationship between Rm and chemical affinity. These expressions can be approximated by second order affinity-based rate laws only under special conditions: (1) growth proceeds only by the development of single-sourced, single spirals and (2) growth occurs at the very near-equilibrium conditions where spiral formation is the only operative mechanism. This suggests that chemical affinity-based rate laws obtained by measuring temporal changes in solution chemistry yield composite rates from different dislocation sources and do not generally give meaningful interpretations of growth mechanism. By combining direct observations with macroscopic methods, improved rate laws with greater predictive capabilities may be possible.

AN - 52275415; 2001-006905 AB - A popular model for the origin of the Tibetan plateau invokes rapid uplift at approximately 8 Ma resulting from lithospheric delamination. Numerous data have been used to support this model, including onset of extension in one well-dated Tibetan graben, a shift in plant communities from C3- to C4-dominated, and changes in Indian Ocean sedimentation patterns, all occurring at about 8 Ma. Independent GCM's further indicate that rapid plateau uplift should have initiated or intensified the monsoon throughout southeastern Asia and the Indian subcontinent. Thus, if Tibetan uplift indeed occurred rapidly at approximately 8 Ma, there should be a readily recognizable change in climate seasonality (i.e., variations in temperature and/or rainfall patterns), with low seasonality prior to 8 Ma, and high seasonality after 8 Ma. New oxygen isotope data from fossil tooth enamel from the Siwaliks of Pakistan show little difference in seasonal climate intensity from at least 9.5 Ma to the present. 61 analyses from 1 bovid and 9 equid teeth reveal smooth changes in isotope composition along each tooth, consistent with seasonal changes in climate. These data show a shift from an average composition of approximately 18 per mil (SMOW) at 9.5 Ma to approximately 23.5 per mil at 0-3 Ma, as expected from well-documented changes in animal diet from C3- to C4-dominated during this time (C4 plants have a higher d18O compared to C3 plants). Most importantly, however, there is little obvious change in isotope variability: samples from 9.5 Ma vary between 15 and 20 per mil, whereas samples from 0-3 Ma vary between 21 and 26 per mil. The approximately 5 per mil variation in 0-3 Ma samples closely matches the approximately 5 per mil seasonal variation observed in Pakistani river water. The lack of a significant change in isotope seasonality between 3 and 9.5 Ma implies the Asian monsoon was already intensely active by 9.5 Ma. Thus if indeed the Asian monsoon was triggered by the establishment of some critical plateau elevation, then that elevation must have been reached prior to 9.5 Ma.

Complex proteins and their amino acid residues are believed to play determinate roles in biomineralization phenomena but their effects on kinetics, thermodynamics, and growth morphology are not understood. Advances in our ability to unravel biologically-induced mineralization by microscopic in situ observation have rejuvenated interests in understanding how microbes and higher organisms synthesize minerals at very near-equilibrium conditions.This study quantifies the effect of amino acids and related organic compounds on step migration rates for the (104) calcite surface using in situ Fluid Cell AFM. L-aspartic and L-glutamic acids are abundant in natural biomineralizing systems while maleic, malonic, and L-alpha-aminobutyric acids were selected to probe mechanisms by which individual functional groups modify growth. Experiments were conducted using control and 0.01 molal organic-doped solutions, at pH = 8.5, IS = 0.1, and supersaturations = 0.6-1.2. Calcium and carbonate activity ratios were adjusted to approximately 1.0 for each solution. Measurements of step velocities show that glutamic acid acts as an overall inhibitor to single spiral growth. In contrast, L-alpha-aminobutyric acid, which lacks a carboxylic functional group, increased step velocities. All of the compounds affected growth morphology by changing and rounding the dominant step edge directions except L-alpha-aminobutyric acid. The extents of the rate enhancing/inhibiting effects were dependent upon supersaturation. These findings indicate the site-specific interactions of carboxyl and amine groups with the four types of kink sites found at calcite step edges. Our analysis suggests that unique growth geometries result from perturbations in microscopic kinetics and possibly thermodynamics.

The incorporation of Mg (super 2+) into magnesian calcite is of particular interest due to its ubiquitous occurrence as an impurity in carbonate biominerals and the accompanying organism-specific controls on Mg content through the complex processes of biomineralization. A complete understanding of the macroscopic processes that govern calcium carbonate formation in Mg-bearing biogeochemical environments, requires a microscopic understanding of the mechanisms involved. Contact mode fluid-cell Atomic Force Microscopy (AFM) was used to determine the effect of Mg (super 2+) on calcite growth kinetics in a flow-through environment. The parameters fundamental to calcite mineralization, step velocity (v) and hillock slope (p), were measured through in situ observations of individual growth spirals, as a function of supersaturation and Mg (super 2+) impurity levels. Individual step velocities for both the (+) and (-) vicinal faces were measured to be uninhibited in solutions with [Mg (super 2+) ]/[Ca (super 2+) ] up to 0.2, although steps along the (-) direction appeared to be pinned by an impurity fence. At higher [Mg (super 2+) ]/[Ca (super 2+) ], step velocities along both directions steadily decreased, and step edges along all directions were significantly pinned by impurities. Complete inhibition of growth was observed as [Mg (super 2+) ]/[Ca (super 2+) ] approached two. Significant changes in hillock morphology that resulted from deviations in both the dominant growth direction and terrace widths were observed as a function of Mg. The step velocity and terrace width data are consistent with established crystal growth impurity models for inhibition by incorporation. Findings from this study are the first to document the microscopic role of magnesium in mediating calcite growth kinetics and the first to determine the mechanism of inhibition within the context of crystal growth impurity models.

We measured 10Be and 26Al in 16 sediment and 8 bedrock samples representing sediment sources and sinks. We use these data to determine long-term, time-integrated (10 (super 4) years) rates of sediment generation, identify sediment source areas and sediment generation processes, and compare rates of bedrock erosion for different lithologies. We calculated a basin-wide bedrock-equivalent lowering rate of 29+ or -6 m/My and, assuming steady-state, a long-term sediment export rate of 79+ or -17 tons/km (super 2) /yr from channel sediment collected near the outlet of Nahal Yael. Our data yield erosion rate estimates slightly lower (36%) than sediment export rates calculated using the historical sediment loading data. Measurement of cosmogenic nuclides in geomorphic features provides insight into processes shaping desert environments. Throughout most of the basin (excluding the uppermost highlands), average 10Be concentrations measured in the bedrock samples (2.4+ or -0.63X10 (super 5) atoms/g) were significantly greater than those measured in the channel sediment (1.25+ or -0.04X10 (super 5) atoms/g), hillslope colluvium (1.25+ or -0.05X10 (super 5) atoms/g), and basin alluvium stored in terraces (1.56+ or -0.15X10 (super 5) atoms/g). These data suggest that most sediment is generated on the hillslopes under colluvial cover rather than from weathering of exposed bedrock. The slightly higher nuclide concentrations measured in basin alluvium as compared to channel sediment and hillslope colluvium indicate sediment storage for a minimum of 5 ky. Additionally, nuclide data suggests differences in rates of erosion for different lithologies. From our data, we find that gneissic granite erodes more slowly (13.8 + or - 3.4 m/My), than pelitic schist (28.0+ or -19.6 m/My) or amphibolite (16.5+ or -5.4 m/My).

These methods have been used to successfully date shallow groundwater in numerous settings. CFC ages are based on the atmospheric growth curve of CFCs and the solubility relationship between dissolved gases and natural waters. The Tritium/ (super 3) He method of groundwater dating is based on the decay relationship between tritium derived primarily from thermonuclear bomb tests in the early 1960s, and its daughter isotope, (super 3) He (half-life = 12.43 yr). Tracer ages produced by both methods agree reasonably well, however, the Tritium/ (super 3) He ages are systematically younger. The difference between the tracer ages is most likely caused by a relatively deep unsaturated zone (causing the CFC concentration of the soil air at the water table to lag behind the free atmosphere). Degradation of CFC can be ruled out because (1) the spring water is oxygenated and (2) the CFC-11 and CFC-12 ages agree. Mixing with a very old water (>50 yrs) seems unlikely because of the relatively low (super 4) He concentrations. Excellent agreement was found between the calculated tracer ages and the chemistry of the spring waters in the study area. Springs with similar tracer ages had very similar chemistry despite the fact that they could be found in different areas of the watershed. With increasing age of the spring water, there is an increase in total conductivity, suggestive of more evolved groundwaters and longer exposure to chemical weathering reactions. This is further evidenced by the similar correlation between calcium, the primary cation released by chemical weathering reactions in this area, and tracer age. Calculated chemical weathering rates decrease with increasing spring water age.

The solubility data were regressed to derive the cumulative and stepwise hydrolysis constants for Ti(IV) in aqueous solution. The data were accurately modeled using the hydrolysis species: Ti(OH)3(+), Ti(OH)4(aq) and Ti(OH)5(-). The following cumulative hydrolysis constants (log K, reactions written with respect to the solid oxide) and stepwise hydrolysis constants were determined by regression. These data are required to model the aqueous geochemical behavior of Ti(IV) in solution and provide a baseline for the Ti solubility-limited radionuclide release rates for ceramic titanate wasteforms of interest to the Plutonium Immobilization Project.

The test specimen is a 0.25 X 0.25 X 0.50 m rectangular prism bisected by an artificial (saw-cut) fracture orthogonal to the tuff fabric. Water was supplied by a point source at the center of the fracture under various pressures of up to 0.04 MPa. Both fluid flow and mechanical properties were found to be anisotropic and strongly correlated with the ash flow fabric. Fluid mass-balance measurements revealed that only minor imbibition of water occurred through the fracture surfaces and that flow rates were independent of normal stress to 14.0 MPa and temperature to 140 degrees C. Flow through the fracture occurred largely through un-correlated porosity that intersected the fracture plane.

Using a finite-difference code, we compute thermal stress changes. We evaluate possible permeability enhancement resulting from shear slip along various mapped fracture sets after 50 years of heating, for rock in the near-field environment of the proposed repository. Our results indicate permeability enhancement of a factor of 2 for regions about 10 to 30 m above drifts, for north-south striking vertical fractures. Shear slip and permeability increases of a factor of 4 can occur in regions just above drifts, for east-west striking vertical fractures. Information on how permeability may change over the lifetime of a geologic repository is important to the prediction and evaluation of repository performance.

In the SHT, a horizontal, 5-m-long, line-heat source was used to heat a rock pillar for nine months. Moisture movement was monitored during and after heating using electrical-resistance tomography (ERT) and neutron-logging techniques. Results indicate drying in regions of the rock where temperature reached 60 degrees C and above. The drying zone is asymmetric and is not centered on the heater, but has lobes extending above and to the sides of the heater. Predicted temperatures agreed well with observations. A coldtrap effect was predicted, in the heater borehole, that efficiently transfers heat along the heater borehole to the excavation wall. A simple thermomechanical analysis of the SHT shows that shear zones predicted for vertical fractures coincide with regions of increased moisture content derived from ERT measurements.

Geothermal field fluids ( approximately 12-14 ka) appear derived from water similar in composition to non-thermal groundwater observed today in valley artesian wells (also approximately 14 ka). Geothermal fluid interaction with mafic rocks (Humboldt Lopolith) appears to be common, and significant reaction with granodiorite may also occur. Despite widespread occurrence of carbonate rocks, largescale chemical interaction appears minor. Age asymmetry of the ranges, more extensive interaction with deep-seated waters in the west, and distribution of springs and artesian wells suggest the existence of a regional upward hydrologic gradient with an axis in proximity to the Stillwater range.

Similar to previous measurements on samples from The Geysers, CA, we observed a gradual increase in resistivity when pore pressure was decreased below the phase-boundary pressure of free water, an indication that boiling is controlled not only by temperature and pressure, but also by pore size distribution. Other important phenomena observed were strong resistance fluctuations during boiling that may be chaotic, and salt deposition that caused sample cracking.

Aseismic areas correlate with zones of abnormally high pore fluid pressures (AHPs) >130% of hydrostatic. Level line surveys suggest that aseismic areas have experienced significant historical uplift. Moreover, these aseismic areas show a remarkable correlation with perennial saline springs that represent technically expelled formation fluid, as indicated by their perennial flow, delta (super 18) O and delta D enrichment to +6.3 per mil and -13 per mil respectively, elevated [B] to 331 ppm, and chemistry dominated by Na and Cl. Aseismic areas are dominantly located at the center of structural blocks that are under compression and are bounded by major faults and seismicity belts. Volumetric strain within these blocks creates pockets of overpressured formation fluid that greatly reduce seismic activity while promoting aseismic uplift. Seismic cross sections reveal three-dimensional pockets of aseismicity that are floored and surrounded by scattered hypocenters. We suggest that overpressured formation fluids originate at depths of 1 to 7 km within these pockets, on the basis of Na-K-Ca geothermometry estimates that are consistent with stratigraphic information and available drill hole data. These overpressured fluid pockets may also influence seismicity on major faults, such as the upper 3 km of the active Greenville fault, which is relatively aseismic where it separates two overpressured pockets. Decreasing flow rates observed at some saline springs may represent a local transition to a period of increased seismic activity. While many studies have linked generation of earthquakes to man-made fluid overpressures, our data show that the dominant, long-term effect of AHPs is to reduce seismicity and promote uplift.

The experiments were performed in an internally heated, gas-pressure vessel with a load train that produced strain rates between 10 (super -6) and 10 (super -5) s (super -1) . Samples were deformed at temperatures of 354 degrees to 502 degrees C and pressures of 100 to 170 MPa in atmospheres of Ar or mixtures of 95% CO (sub 2) with 5% CO or 5% CH (sub 4) , compositions that are well within the field of graphite stability at the run conditions. In experiments using Nugget sandstone, resistance reached a minimum value when the maximum temperature was achieved and good electrode contact was made. The resistance then increased as the experiment continued, probably due to dry out of the sample, a change in the oxidation state of the Fe-oxide associated with the cement, or destruction of current-bearing pathways. At approximately 200-MPa end load, the rock sample failed. Plots of load and resistance versus time show several interesting features. In one experiment, for example, as the end load reached about 175 MPa, resistance stopped increasing and remained fairly constant for a period of approximately 0.5 hour. During loading, the end load displayed small decreases that were simultaneous with small decreases in resistance; when the end load (and the displacement) indicated rock failure, resistance decreased dramatically, from approximately 150 MOmega to 100 MOmega . In a single experiment, the Westerly granite also showed a decrease in resistance during dilatancy. The nature and distribution of carbon in the run products were studied by electron microprobe and time-of-flight secondary-ion mass spectroscopy (TOP-SIMS). Carbon observed by mapping with the former is clearly observed on micro-cracks that, based on the microtexture, are interpreted to have formed during the deformation. The TOF-SIMS data confirm the electron-probe observations that carbon is present on fracture surfaces. These observations and experimental results lead to the hypothesis that as microfractures open in the time leading up to failure along a fracture, carbon is deposited as a continuous film on the new, reactive mineral surfaces, and this produces a decrease in resistance. Subsequent changes in resistance occur as connectivity of the initial fracture network is altered by continued deformation. Such a process may explain some electromagnetic effects associated with earthquakes. Copyright 1999 by the American Geophysical Union.

The results of isotopic analyses are first described then a 2-dimensional scoping model developed to gain insights into the groundwater movement revealed by the analyses. The production of a more realistic 3-dimensional model of groundwater flow in the forebay recharge area is discussed. The model was based on a new representation of geological heterogeneity which was known to influence local flow and transport behaviour in the subsurface. It and the isotopic analyses helped the understanding of flow paths, migration rates and residence times of recharged groundwater and the identification of source composition. These issues were important from the perspective of the regulation of recharge facilities and nearby production wells. Although isotopic estimates of groundwater age served to discriminate between several equally acceptable simulations calibrated to head data only, the results also suggested that groundwater reaching a well spanned a wide range of ages, thus demonstrating the importance of geological heterogeneity. Detailed results are shown for the region. JF - Water Resources Research AU - Tompson, AFB AU - Carle, S F AU - Rosenberg, N D AU - Maxwell, R M AD - Lawrence Livermore National Laboratory, Calif.

The versatility of SPH is offset by its computational expense which limits the practicability of SPH for large problems involving low Reynolds number flow. A parallel pore-scale numerical model based on SPH is described for modeling flow phenomena in porous media. Aspects of SPH which complicate parallelization are emphasized. The speed of the method is demonstrated to be proportional to the number of processors for test cases where load balance was achieved. The parallel algorithm permits the application of SPH to more complicated porous media problems than previously considered. For such problems, best performance is achieved when several soil grains are simulated by each processor. Finally, future applications of the method and possible extensions are discussed.

The variation is consistent with higher-latitude recharge following continuous flow paths along north-south trending graben valleys and systematically increasing in delta super(18)O due to mixing with lower-latitude, higher- delta super(18)O recharge. The data do not suggest that large masses of groundwater with unusually low delta super(18)O values were recharged during the last pluvial period as suggested by previous workers. Many delta super(18)O- delta D pairs in groundwater indicate variable amounts of evaporation relative to the global meteoric water line. The precipitation rate and type (rain versus snow) for a given geographic area controls the extent of evaporation. A "model" delta super(18)O value was calculated from evaporated groundwaters by subtracting postcloud evaporation. The distribution of these model delta super(18)O values suggest new regional groundwater flow paths previously undocumented. Dissolved inor anic carbon in groundwaters collected from deep regional flow systems typically has low super(14)C concentrations ( less than or equal to 12% modern carbon). In contrast, groundwaters collected from the carbonate rock of the Spring Mountains and alluvium of Forty Mile Canyon have higher super(14)C contents, indicating more recent recharge. Because of nonlinear mixing of super(14)C, groundwater in the regional flow system likely acquired most of its observable super(14)C from mixtures of young, locally recharged groundwater.

AN - 69168849; 10022292 AB - DNA adducts are nucleotide bases that have been covalently modified by reactive electrophilic chemical intermediates, and have been extensively researched for their role in mutagenesis and carcinogenesis. However, many DNA adduct measurement techniques have difficulty in the quantification of adducts at realistic human exposure levels. We are using the extremely sensitive analytical technique of accelerator mass spectrometry (AMS) to study adducts either at low dose or directly in humans. AMS is a technique for measuring isotope ratios with high selectivity, attomole sensitivity (10(-18) mol) and precision of 0.5-10%, depending on isotope level and preparation method. This sensitivity and precision is being used to study the dose-response, toxicokinetics, and toxicodynamics of DNA adduct formation and removal following administration of very low doses of chemicals.

AN - 69170343; 9988374 AB - A mechanistically based cytodynamic two-stage (CD2) cancer model was shown recently to predict both ecologic US county data and underground-miner data on lung-cancer mortality (LCM) vs radon concentration, indicating biological plausibility of the apparent negative dose-response relation exhibited by the ecologic data. To further investigate this hypothesis, the CD2 model was fitted to combine age-specific LCM data vs estimated radon-exposure in white females of age 40+ years in 2821 US counties during 1950-1954 using new estimates of county-specific mean residential radon exposure, and in five cohorts of underground nonsmoking miners. The negative association of radon levels and corresponding county-level LCM rates apparent in women dying in 1950-1954 (11% of whom never smoked) was also apparent in women of age 60+ years (5% of whom never smoked). The CD2 fit obtained to the combined residential and occupational data was found to predict the combined data using biologically plausible parameter values, and also to predict inverse dose-rate effects exhibited in nonsmoking miner data to which the CD2 model was not fit. These results are consistent with the hypothesis that residential radon exposure has a nonlinear U-shaped relation to LCM risk, and that current linear extrapolation models substantially overestimate such risk.

Experiments with typical seawater microbial populations were contrasted with a sterile control, and reactions were monitored chemically and isotopically. Biologically mediated experiments produce twice the mass of authigenic phases than abiotic experiments and the phases are different. Abiotic alteration of glass dissolves basaltic Si and Ca and scavenges seawater Mg, while biotic alteration removes Ca from seawater. Such opposing behavior of Ca and Mg in biotic and abiotic alteration of basaltic glass may have important implications for the carbon cycle and the exchange processes between ocean crust and seawater. (super 87) Sr/ (super 86) Sr data of glass and alteration products suggest that biological mediation enhances both the diffusion of seawater Sr into glass by a factor of 3-4, and the dissolution of basaltic Sr into seawater by a factor of 20-40. The dependence of chemical exchange processes between seawater and glass on biological activity implies that chemical fluxes from water-rock interaction at low temperatures may change as life on Earth evolves.

AN - 52506365; 1999-018671 AB - The top 20 cm of sediments at active cold seeps in Monterey Bay, coastal California, contain framboidal pyrite that occurs as infillings and pseudomorphs of the chambers of the tests of foraminifera and rarely as irregularly shaped grains. Sulfur isotope compositions obtained with the ion microprobe show depletions in (super 34) S (delta (super 34) S = -41 to -5 per mil, CDT), and large variations both within and among these pyrite grains. Intergranular differences in delta (super 34) S values in the same sediment are as large as 35 per mil, and intragranular zoning reaches 15 per mil. Zoning is regular in some grains, with systematic isotope changes from core to rim or from one foraminiferal chamber to another, but irregular in others. The regular zoning is consistent with an increase in (super 34) S through time. Backscattered-electron imaging reveals three types of pyrite: isolated framboids in a porous aggregation ("PF-pyrite"), agglomerated framboids with cementing interstitial pyrite ("F+I-pyrite"), and recrystallized pyrite with isolated relicts of framboids ("RF-pyrite"). In individual grains, RF-pyrite cores grade into F+I-pyrite toward grain rims, and F+I-pyrite grades into PF-pyrite at the grain edges. These textures are consistent with a paragenetic sequence whereby framboids first agglomerate (PF-pyrite), then cement (F-I-pyrite), and finally recrystallize (RF-pyrite). The delta (super 34) S values of RF-pyrite are generally lower than that of F+I-pyrite; if the paragenetic sequence is correct, then this trend parallels the regular core-rim isotopic zoning observed in some grains. The implied increase in delta (super 34) S with time is consistent with Rayleigh fractionation of sulfur in a closed system. Bacteria are intimately involved in the production of pyrite from our samples, and heterogeneous colonization by bacteria provides a simple explanation for the sulfur isotope heterogeneity among and within grains: The foraminifera provide open space for colonization and local nutrients for bacterial growth, whereas the cell walls of the bacteria may provide a local nucleation site for sulfides. If so, then initial colonization is reflected in lower delta (super 34) S values, whereas later bacterial emigration to other foraminifera chambers is indicated by higher delta (super 34) S values.

Spectra from samples recovered from shock pressures of 12-20 GPa show a broadening of the (super 29) Si NMR peak and the development of asymmetry toward lower NMR frequency (indicating an increase in the mean Si-O-Si intertetrahedral bond angle). NMR spectra of samples shock compressed above approximately 25 GPa show increasing amounts of a separate amorphous phase of SiO (sub 2) with a mean Si-O-Si bond angle roughly 5 degrees narrower, and 10-15% denser, than fused SiO (sub 2) . Small amounts of crystalline material remain with a mean Si-O-Si bond angle up to 3 degrees larger than unshocked alpha -quartz. The recovery of dense glass indicates that post-shock temperatures were sufficiently low to also preserve stishovite, had any been created in our experiments. The paucity of stishovite or (super [6]) Si in an amorphous phase in our recovered samples suggests that the formation of stable, high-coordinated Si is kinetically hindered in shock compression experiments up to about 35-40 GPa, except in regions of high temperature, such as planar deformation features (PDFs), microfaults (pseudotachylites), or voids.

Three water types were distinguished with the tracers, each having a very different history. Two of the water types were found in south-eastern Colorado where the Dakota is poorly confined. The tracer data suggest that the first group recharged locally during the last few thousand years and the second group was composed of ground water that recharged earlier during a cooler climate, presumably during the last glacial period (LGP) and mixed aged water. The paleotemperature record archived in this groundwater system indicates that south-eastern Colorado was about 5 degrees C cooler during the LGP than during the late Holocene. Similar temperature changes derived from dissolved noble gases in other aquifer systems have been reported earlier for the south-western United States. The third water type was located down gradient of the first two in the confined Dakota in western and central Kansas. Groundwater residence time of this water mass is on the order of 104-105 yrs and its recharge location is near the Colorado and Kansas border down gradient of the other water types. The study shows the importance of using multiple tracers when investigating ground water systems.

AN - 70006457; 9797104 AB - OBJECTIVETo determine whether moderate cigarette smoking and alcohol consumption in teenage men is associated with increases in disomic sperm and detectable changes in semen quality.DESIGNCohort study.SETTINGMilitary recruiting station, Teplice, Czech Republic.PATIENT(S)Ten current smokers (20 cigarettes per day for at least 2 years, exposure confirmed by urine cotinine) who also consumed alcohol and 15 nonsmokers. All patients were exactly 18 years old, healthy, and of unproven fertility.MAIN OUTCOME MEASURE(S)Sperm aneuploidy by multicolor fluorescence in situ hybridization for chromosomes 8, X, and Y; conventional semen analyses; computer-aided sperm analysis for motility; and sperm chromatin structure analysis.RESULTSSmokers showed elevated frequencies of sperm aneuploidy (Y disomy, P <0.001; aggregate of X, Y, and 8 disomies, P <0.01); reduced linearity of sperm motion (P <0.05); and more "round-headed" sperm (P <0.01). Smokers' semen contained fewer sperm (P <0.001) and fewer motile sperm (P <0.02), which was attributable, in part, to shorter abstinence intervals among smokers (P <0.02).CONCLUSION(S)Cigarette smoking among teenagers was associated with increases in disomic sperm and a diminution in specific aspects of semen quality. Such defects may affect male fertility and may increase future chances of fathering offspring with aneuploidy syndromes.

AN - 69970443; 9778319 AB - This is the first demonstration of the use of accelerator mass spectrometry (AMS) as a tool for the measurement of 3H with attomole (10(-18) mol) sensitivity in a biological study. AMS is an analytical technique for quantifying rare isotopes with high sensitivity and precision and has been most commonly used to measure 14C in both the geosciences and more recently in biomedical research. AMS measurement of serially diluted samples containing a 3H-labeled tracer showed a strong correlation with liquid scintillation counting. The mean coefficient of variation of 3H AMS based upon the analysis of separately prepared aliquots of these samples was 12%. The sensitivity for 3H detection in tissue, protein, and DNA was approximately 2-4 amol/mg of sample. This high sensitivity is comparable to detection limits for 14C-labeled carcinogens using 14C AMS and demonstrates the feasibility of 3H AMS for biomedical studies. One application of this technique is in low-dose, dual-isotope studies in conjunction with 14C AMS. We measured the levels of 3H-labeled 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and 14C-labeled 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) in rat liver tissue and bound to liver DNA and protein 4.5 h following acute administration of individual or coadministered doses in the range of 4-5100 pmol/kg of body weight. Levels of PhIP and MeIQx in whole tissue and bound to liver protein were dose-dependent. MeIQx-protein and -DNA adduct levels were higher than PhIP adduct levels, which is consistent with their respective carcinogenicity in this organ. Coadministration of PhIP and MeIQx did not demonstrate any measurable synergistic effects compared to administration of these compounds individually. These studies demonstrate the application of AMS for the low-level detection of 3H in small biological samples and for its use in conjunction with 14C AMS for dual-labeling studies.

AN - 69954414; 9768853 AB - Radiation exposures from tritium make up a substantial fraction of the occupational and accidental radiation exposures associated with the nuclear power industry. Tritiated water, the most abundant form of tritium, is of particular interest because it is readily taken up by human cells and its irradiation of the cells is spread over a period of days. To approximate the prolonged exposure and the conditions that the cells of an individual would experience in vivo, we irradiated human lymphocytes with tritiated water for 48 h in a 1:1 blood:medium mix. For estimation of the tritium beta-ray dose, a cellular water content of 0.78, based on measurements of human lymphoblastoid cells in culture medium, was used. A modified dose calculation formula was developed for the radiation exposure conditions. A total of 48,014 metaphases (14,482 in irradiated samples and 33,532 in control, unirradiated samples) in human lymphocytes cultured for 72 h after exposure were analyzed for chromosome translocations using fluorescence in situ hybridization. The linear slope (alpha coefficient) of the dose-response curve was measured to be (3.93+/-0.42) x 10(-2) and (5.26+/-0.48) x 10(-2) translocations per cell per gray for complete translocations (tc) and complete translocations plus incomplete translocations [ti(Ab)], respectively, when the data were fitted to a linear model using a weighted least-squares method. The alpha coefficient for tc is significantly lower than that for conventionally measured dicentrics after tritium beta irradiation, but the alpha coefficient for tc + ti(Ab) does not differ significantly from that for dicentrics. This is in agreement with theoretical considerations. The importance of scoring criteria is stressed.

These inaccuracies are caused by inherent averaging in the model, and, as a result, exact data values cannot be directly recovered at a point in the model. Seismic characterization involves cataloging reference events so that inaccuracies in the model can be mapped at these points and true data values can be retained through a correction. Application of these corrections to a new event requires the accurate prediction of the correction value at a point that is near but not necessarily coincident with the reference events. Given that these reference events can be sparsely distributed geographically, both interpolation and extrapolation of corrections to the new point are required. In this study, we develop a closed-form representation of Bayesian kriging (linear prediction) that incorporates variable spatial damping. The result is a robust nonstationary algorithm for spatially interpolating geophysical corrections. This algorithm extends local trends when data coverage is good and allows for damping (blending) to an a priori background mean when data coverage is poor. Benchmark tests show that the technique gives reliable predictions of the correction value along with an appropriate uncertainty estimate. Tests with travel-time residual data demonstrate that combining variable damping with an azimuthal coverage criterion reduces the large errors that occur with more classical linear prediction techniques, especially when values are extrapolated in poor coverage regions. In the travel-time correction case, this technique generates both seismic corrections along with uncertainties and can properly incorporate model error in the final location estimate. Results favor the applicability of this nonstationary algorithm to other types of seismic corrections such as amplitude and attenuation measures.

Recent observations of experimentally induced transformations between (Mg,Fe) (sub 2) SiO (sub 4) olivine (alpha ) and its high pressure polymorphs, wadsleyite (beta ) and ringwoodite (gamma ), demonstrate that both these assumptions can be invalid, thus complicating the extrapolation of experimental kinetic data. Incoherent grain boundary nucleation appears to have dominated in most previous experimental studies of the alpha -beta -gamma transformations because of the use of starting materials with small (<10-20 mu m) grain sizes. In contrast, when large (0.6 mm) olivine single crystals are reacted, intracrystalline nucleation of both beta and gamma becomes the dominant mechanism, particularly when the P-T conditions significantly overstep the equilibrium boundary. At pressures of 18-20 GPa intracrystalline nucleation involves (i) the formation of stacking faults in the olivine, (ii) coherent nucleation of gamma -lamellae on these faults and (iii) nucleation of beta on gamma . In other experiments, intracrystalline nucleation is also observed during the beta -gamma transformation. In this case coherent nucleation of gamma appears to occur at the intersections of dislocations with (010) stacking faults in beta , which suggests that the nucleation rate is stress dependent. Reaction rims of beta /gamma form at the margins of the olivine single crystals by grain boundary nucleation. Measurements of growth distance as a function of time indicate that the growth rate of these rims decrease towards zero as transformation progresses. The growth rate slows because of the decrease in the magnitude of the Gibbs free energy (stored elastic strain energy) that develops as a consequence of the large volume change of transformation. On a longer time scale, growth kinetics may be controlled by viscoelastic relaxation.

The data are assembled for assessing quantitatively the hypothesis that dense, aqueous fluids are the medium for mass transfer of B, Be and Li during subduction, and that these elements in fluid coexist with phases that may be residual during high-P slab dehydration. A model is presented for the behaviour of these elements during progressive dehydration of the oceanic crust. Average clinopyroxene-fluid partition coefficients are approximately 0.02 (B), approximately 2 (Be) and approximately 0.2 (Li) and are 100 X (B, Li) to 1000 X (Be) larger than values for garnet. A comparison of clinopyroxene-fluid partition coefficients for B-Be, B-Nb and Li-Yb with clinopyroxene-silicate melt values shows that B/Be, B/Nb and Li/Yb ratios will be significantly fractionated in coexisting aqueous fluid with respect to the residual solid. Raised ratios of these elements in island arc lavas relative to MORB are consistent with their origin by fluid-mediated slab-to-mantle transport. When a slab reaches a depth of 200 km, B/Be and B/Nb in the dehydration residue has been reduced to approximately 5-12 % of initial values.

Plasmid pPCP1 (9.610 bp) has a GC content of 45.3% and encodes two previously known virulence factors, an associated protein, and a single copy of IS100. Plasmid pCD1 (70,504 bp) has a GC content of 44.8%. It is known to encode a number of essential virulence determinants, regulatory functions, and a multiprotein secretory system comprising the low-calcium response stimulation that is shared with the other two Yersinia species pathogenic for humans (Y. pseudotuberculosis and Y. enterocolitica). A new pseudogene, which occurs as an intact gene in the Y. enterocolitica and Y. pseudotuberculosis-derived analogues, was found in pCD1. It corresponds to that encoding the lipoprotein YlpA. Several intact and partial insertion sequences and/or transposons were also found in pCD1, as well as six putative structural genes with high homology to proteins of unknown function in other yersiniae. The sequences of the genes involved in the replication of pCD1 are highly homologous to those of the cognate plasmids in Y. pseudotuberculosis and Y. enterocolitica, but their localization within the plasmid differs markedly from those of the latter. Plasmid pMT1 (100,984 bp) has a GC content of 50.2%. It possesses two copies of IS100, which are located 25 kb apart and in opposite orientations. Adjacent to one of these IS100 inserts is a partial copy of IS285. A single copy of an IS200-like element (recently named IS1541) was also located in pMT1. In addition to 5 previously described genes, such as murine toxin, capsule antigen, capsule anchoring protein, etc., 30 homologues to genes of several bacterial species were found in this plasmid, and another 44 open reading frames without homology to any known or hypothetical protein in the databases were predicted.

Both the strain field and mode of magmatism (plutonism vs. volcanism) in the late Miocene Peruvian Andes were controlled by the degree to which the arc-parallel component of the plate slip vector was partitioned into the arc. Strong strike-slip partitioning at ca. 8 Ma produced arc-parallel sinistral shear, strike-slip intercordilleran basins and east-west-oriented tension fractures that facilitated emplacement of the Cordillera Blanca batholith (ca. 8.2+ or -0.2 Ma). Periods during which the strike-slip component was not partitioned into the arc (ca. 10 and ca. 7 Ma) were associated with roughly arc-normal contraction and ignimbrite volcanism. The data thus support the contention that contraction within continental magmatic arcs favors volcanism, whereas transcurrent shear favors plutonism. The tie between oblique convergence and batholith emplacement in late Miocene Peruvian Andes provides a modern analogue for batholiths emplaced as the result of transcurrent shear in ancient arcs.

This program is unique because of elevated levels of radioactivity encountered during drilling (>3.7E+6 Bq/I (super 3) H), extreme completion depths (>950 m), and the expense of constructing new wells (>$1E+6/borehole). Sites of five nuclear tests have been drilled. Three of the events were fired in Yucca Flat which is a hydrologically closed basin and two were fired in fractured volcanics of Pahute Mesa. Results from Yucca Flat indicate that volatile and refractory radionuclides, fractionated at zero time, are not highly mobile under saturated conditions. In contrast, boreholes completed on Pahute Mesa intercept high concentrations of tritium (>3.7E+6 Bq/I (super 3) H) and other radionuclides transported more than 300 m from event cavities as dissolved species or as colloids.

Recrystallized, granulite-facies (725 degrees C) wollastonite ores from the N Adirondack highlands essentially contain clinopyroxene (a Di-Hd solid solution) + garnet (a Grs-Adr solid solution) + or - wollastonite, and exhibit a systematic dependence of measured fractionations on the Fe (super 3+) content of calcic garnet: Delta (Cpx-CaGrt) = (0.14 + or - 0.12) + (0.78 + or - 0.20)X (sub Adr) and Delta (Wo-CaGrt) = (0.15 + or - 0.22) + (0.57 + or - 0.33)X (sub Adr) . In eclogites formed at T < or = 650 degrees C: measured compositions of Ca-poor garnet and omphacite combined with experimental data indicate that Ca-poor, Fe-rich garnet is enriched in (super 18) O compared to both diopside and grossular. Extrapolating to 1000 K, Delta (Alm-Di) approximately 0.2% and Delta (Alm-Grs) approximately 0.5%. Orthopyroxene and clinopyroxene from Gore Mountain, New York, show a constant fractionation, independent of rock type, as expected if they have the same closure T. These data imply Delta (Opx-Cpx)Delta approximately 0.7% at 1000 K. Measured fractionations among Ca-poor garnet, orthopyroxene, clinopyroxene and hornblende in the Gore Mountain rocks further indicate an (super 18) O enrichment in Ca-poor garnet over Grs ( approximately 0.5% at 1000 K). The new measurements consistently indicate a significant isotope effect for the simple octahedral cation substitutions Fe (super 3+) Al (sub -1) (Grs vs Adr) and Ca(Fe,Mg) (sub -1) (Ca-poor garnet vs Grs; Opx vs Cpx).

The refined model coordinates have a rms deviation of 0.22 Ae relative to the same structure determined at room temperature and 2.0 Ae resolution. Several regions of main-chain and side-chain disorder have been identified for 21 out of 269 residues in one polypeptide chain. Hydrogen atoms appear as significant peaks in the F sub(o) - F sub(c) difference electron density map, and carbon, nitrogen, and oxygen atoms can be differentiated. The estimated standard deviation (ESD) for all main-chain non-hydrogen bond lengths is 0.009 Ae and 0.5 degree for bond angles based on an unrestrained full-matrix least-squares refinement. Hydrogen bonds are resolved in the serine protease catalytic triad (Ser-His-Asp). Electron density is observed for an unusual, short hydrogen bond between aspartic acid and histidine in the catalytic triad. The hydrogen atom, identified by NMR in numerous serine proteases, appears to be shared by the heteroatoms in the bond. This represents the first reported correlation between detailed chemical features identified by NMR and those in a cryo-cooled crystallographic structure determination at ultrahigh resolution. The short hydrogen bond, designated "catalytic hydrogen bond", occurs as part of an elaborate hydrogen bond network, involving Asp of the catalytic triad. While unusual, these features appear to have conserved analogues in other serine protease families although specific details differ from family to family.

Comparison of human subjects and F344 rats. AN - 80056133; 9698300 AB - Covalent binding of the food-borne heterocyclic amine 2-amino-3, 8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) to albumin and hemoglobin (Hb), 3.5-6.0 hr after oral administration of a single dose of either 21.3 or 228.0 microg of [14C]MeIQx (304 and 3257 ng/kg of body weight, respectively, based on a 70-kg subject weight), was studied in human volunteers using accelerator mass spectrometry. Human protein adduct levels were compared with data obtained for male F344 rats 4.5 hr after oral administration of 0.94-11,420 ng/kg of body weight [14C]MeIQx. Dose-dependent levels of MeIQx-albumin and MeIQx-Hb adducts were detected in both humans and rats. In each case, the regression coefficient (slope) of the dose-response curve was approximately 1. The highest levels of adduct formation per unit dose of MeIQx occurred with human albumin, followed by rat albumin, human Hb, and rat Hb (in that order). Although the human subjects were elderly and underwent colon resection surgery during the study period, the results indicate that formation of albumin and Hb adducts is dose dependent and that a trend exists for higher adduct levels per unit dose in humans, compared with F344 rats. Furthermore, MeIQx-albumin adducts are likely to provide a more sensitive marker of exposure to MeIQx than are MeIQx-Hb adducts.

AN - 80033142; 9682148 AB - We described the use of Nuclear microscopy (microbeam PIXE) for the quantitative micron scale analysis of platinum based chemotherapeutic agents in individual cell and tissue slices. We demonstrate that microbeam PIXE has the sensitivity and accuracy to quantitatively measure the uptake of the chemotherapeutic agent cis-diamminedichloroplatinum (II) (cisplatin) and monitor other endogenous metal contents in single cells in a time- and dose-dependent fashion. Additionally, the technique can quantitatively image therapeutic levels of cisplatin and cisplatin analogs including cis-diammine[1,1-cyclobutanedicarboxylato] platinum (II) (carboplatin) in tissues from an animal model. This quantitative imaging microscopy has general application for the sensitive measurement of metal containing drugs/compounds at the cellular level and allows the study of cellular distribution and mechanism of action related to toxic response and cell function.

Two terrace risers offset by 24+ or -3 and 33+ or -4 m, having respective ages of 1788+ or -388 and 2914+ or -471 yr, imply a slip rate of 12.1+ or -2.6 mm/yr. The full range of ages obtained (< or =22.8 k.y., most of them between 6.7 and 1.4 k.y.) confirm that terrace deposition and incision, hence landform evolution, are modulated by post-glacial climate change. Coupled with minimum offsets of 9-12 m, this slip rate implies that great earthquakes (M approximately 8) with a recurrence time of 800-1000 yr, rupture the Kunlun fault near 94 degrees E.

The results show that changes in clinopyroxene chemistry produce important shifts in inter-element partitioning. The partition coefficients of HFSE increase by factors of 2-8 due to increased (super [4]) Al in the clinopyroxenes, while other elements show little change between compositions. The relative partitioning of HFSE is also affected by (super [4]) Al variations in the clinopyroxene. The decoupling of HFSE and Sr from the REE in peridotites and melt inclusions may be due to partition coefficient changes due to decreases in clinopyroxene Al (sub 2) O (sub 3) with progressive melting. Depletions of Nb relative to Ta and Zr relative to Hf in mantle-derived magmas, reflect their peridotite source previously depleted by melt extraction in the presence of residual clinopyroxene with moderate Al (sub 2) O (sub 3) amounts.

In cases where a substance is widely used in commerce or is naturally occurring in the environment, compliance costs can be substantial because of nationwide requirements to add expensive control technologies. Uncertainties in a dose-response function further impact risk management decisions because they may correspond to large differences in health benefit per unit exposure reduction. These problems are highlighted in the case of plausibly hormetic environmental carcinogens, for which a linear-no-threshold (LNT) dose-response model has been the traditional regulatory default assumption. In this case, model uncertainty is pivotal, and risk management is consequently inherently controversial. However, marginal cost functions that arise for plausibly hormetic carcinogens are expected to possess a common analytic feature that may be particularly useful for this type of risk management problem. Specifically, marginal cost functions in this context are expected to have roots reflecting contaminant concentration values above which regulatory goals may be optimally placed subject to cost constraints. Here we illustrate this heuristic feature in the case of residential radon, using both a LNT model and a biologically plausible hormetic model to predict associated risks of lung cancer mortality.

In this study, steady-state effluent concentrations and dissolution/precipitation features associated with crushed quartz and tuff dissolution at 240 degree C have been determined experimentally using a plug-flow reactor (PFR) and scanning electron microscopy (SEM) techniques, then modeled with the reactive transport simulator GIMRT using a linear rate law from transition state theory (TST). For quartz dissolution, interdependence of the specific surface area (A sub(m)) and reaction rate constant (k sub(m)) predicted from the modeling agrees closely with that obtained from an analytical solution to the reaction-transport equation without diffusion/dispersion, verifying the advection-dominant nature of the PFR experiments. Independently-determined A sub(qtz) and k sub(qtz) from the literature are shown to be internally consistent with respect to the model and analytical interdependence, implying appropriateness of the linear TST rate law and adequacy of BET-determined A sub(m) for use in modeling PFR experiments. Applications of this integrated approach for monomineralic dissolution include assessment of internal consistency among independent A sub(m) and k sub(m) data, estimation of k sub(m) from BET-determined A sub(m), and rapid evaluation of alternative rate laws. For tuff dissolution, accurate simulation of the experimental steady-state effluent concentrations (to within 3% for Na, Al and K; to within 15% for Si and Ca) and dearth of alteration phases (<1 vol.% in the model) defines minimum supersaturation thresholds for nucleation of primary minerals (to suppress their secondary precipitation) and the (non-unique) relative k sub(m) of hydrous aluminosilicates. For such multicomponent, multiphase experiments, reactive transport simulators provide the only practical means of estimating and constraining these kinetic parameters. Despite the approximations and uncertainties inherent in present-day models, close agreement between the experimental and simulation results reported herein provides an important measure of confidence for extending the modeling approach to address increasingly complex systems for which development of experimental analogs is impractical or impossible.

Quantification of the uncertainties associated with natural attenuation, and hence the capacity to limit plume migration and restore an aquifer, is important. In this study, a probabilistic screening model is developed to quantify uncertainties involved in the impact of biodegradation on hydrocarbon plume behavior. The approach is based on Monte Carlo simulation using an analytical solution to the advective-dispersive solute transport equation, including a first-order degradation term, coupled with mass balance constraints on electron acceptor use. Empirical probability distributions for governing parameters are provided as input to the model. Application of the model to an existing LUFT site illustrates the degree of uncertainty associated with model-predicted hydrocarbon concentrations and geochemical indicators at individual site monitoring wells as well as the roles of various parameter assumptions (e.g., hydraulic conductivity, first-order decay coefficient, source term) in influencing forecasts. This information is useful for risk management planning because the degree of confidence that biodegradation will limit the impact of a hydrocarbon plume on potential receptors can be quantified.

AN - 73876674; 9723009 AB - This personal account relates the advent of mutant isolation and other developments in somatic cell genetics that were critical steps toward isolating DNA repair mutants in mammalian cells. The isolation of auxotrophic and temperature-sensitive mutants in genetically stable Chinese hamster cell during the late 1960s and early 1970s provided a conceptual framework in which to later isolate mutations conferring hypersensitivity to ultraviolet radiation, ionizing radiation, and various chemical mutagens. Complementation group analysis of ultraviolet-sensitive mutants helped identify multiple genes that overlapped with the groups of cancer-prone xeroderma pigmentosum, as well as Cockayne syndrome. The first mammalian cell mutants defective in strand-break repair were also discovered. Subsequent cloning of human genes that corrected CHO-cell mutations in nucleotide-excision repair groups 1-6 later led to identifying the key enzymes in the incision steps of this pathway, as well as the CSB protein, which is involved in coupling excision repair and transcription.

This debris layer (BIT-58) extends parallel to the stratigraphy of the ice established from the tephra bands, apparently marking a single depositional event. The shapes, internal texture, major element composition, and levels of cosmogenic nuclides of particles from within BIT-58 all strongly suggest that this material represents ablation debris from the passage of a large H-group ordinary chondrite. Preliminary cosmogenic isotope dating suggests an age of 2.8 Ma, implying that the East Antarctic ice sheet has been stable since that time. The relationship of the Bit-58 layer to known impact events is not clear.

The continual and costly liability is an important corporate incentive to clean contaminated soils. The development of an effective technology for in situ decontamination is a priority issue. Some in situ decontamination processes are similar to enhanced oil recovery schemes and use an integrated heating approach. One such method consists of heating by conduction and convection in conjunction with electrical heating. Advantages of electrical heating are that the energy can be focussed and the soil heated uniformly. The integrated heating approach has been extensively tested in the United States in a joint venture between Lawrence Livermore National Laboratories (LLNL) and the University of California at Berkeley. The most significant test was done at an abandoned Naval Air Base, now named the LLNL Gasoline Spill Site. It has been demonstrated that such an integrated approach can remove hydrocarbon contaminates from in situ at an accelerated rate. The objective of this paper is to present a mathematical model that solves the heat transfer problem for the integrated heating process. The model is also used to investigate the practicality of the process in terms of energy requirements and the time it takes to clean the soil. The mathematical model combines all of the principal heat transfer mechanisms of the process. These are electrical heating, convection, conduction and accumulation of energy. In addition, conductive heat losses from the sides and bottom of the heated volume and the substantial variation of electrical resistivity with temperature are included. Calculations made using the mathematical model developed in this paper are in good agreement with results obtained with the general-purpose reservoir simulator, TETRAD.

This information is needed to predict the effect of these materials on the performance of geologic radioactive waste repositories. Reaction of large amounts of cement used to build the repository with the surrounding rock and groundwater may cause changes in the hydrologic properties of the repository, impact metal canister and waste form corrosion rates, and alter the mobility of actinides in the subsurface. We have determined that 11 angstrom-tobermorite, calcite and quartz is the stable (or at least metastable) mineral assemblage at 200 degree C of complex experiments containing mixtures of cement, Topopah Spring tuff, diesel fuel and 3 mM NaHCO sub(3) from analyses of the solids and solutions. Mesolite did not form in these experiments, despite predictions that it is the most stable phase. A solubility constant for 11 angstrom-tobermorite was calculated to be equal to 10 super(39.4( plus or minus 1.3)) at 200 degree C for the following reaction: Ca sub(5)(SiO sub(2)) sub(6)(OH) sub(10*)0.5H sub(2)O + 10H super(+) = 5Ca super(2+) + 6SiO sub(2(aq)) + 10.5H sub(2)O. 11angstrom - tobermorite (1). This work shows that reaction periods of at least 20 days are required to reach local equilibrium or steady-state.

The authors couple the flexural plate wave (FPW) gravimetric sensor (S.W. Wenzel, R.M. White, IEEE Trans. Electron Devices 35 (1988) 735-743) with a novel mass-amplifying label that increases sensor signal level (a shift of resonant frequency) from that of previous acoustic immunoassays, in which frequency shifts were due solely to the weight of the immunoglobulins. The use of a gravimetric immunoassay with a mass-amplifying label provides an alternative to radioimmunoassay, eliminating the need for radioactive labels that require costly disposal. In addition to gravimetric sensing, the FPW device is also capable of providing a source of ultrasonic agitation, which results in localized mixing near the active immunoglobulin binding area of the device. The authors have observed increased antibody binding using ultrasonic agitation during immunoglobulin incubation periods. Consequently, with ultrasonic agitation, the authors are able to reduce the length of time necessary to complete the immunoassay and also affect the amount of antibody binding.

B, Be and Li are moderately to strongly incompatible in these minerals, the mineral/melt partition coefficients decreasing in the order for olivine, clinopyroxene and orthopyroxene: Li (0.1-0.2) > Be approximately B (0.002-0.03). Amphibole/melt partition coefficients for Be and Li are similar ( approximately 0.2) and larger than those for B ( approximately 0.02). Combining the partitioning data with simple models of melting and solidification allows the evaluation of the accuracy of B/Be, B/K, B/Nb, Be/Nd, Li/V and Li/Yb ratios in primitive magmas reflecting that of their source. The distinction of IAB and OIB sources relative to MORB should be increased to include B/Be, B/Nb and Li/Yb.

The results show significant O isotope effects associated with cation exchange, and using a new predictive approach, high-T fractionations are reproduced. Although O isotope effects of cation exchanges are generally 500 degrees C, they increase strongly at lower T. Because the cation exchanges in amphiboles also occur in many other minerals, the data presented and predictive approach suggest strong control of O isotope fractionations by mineral chemistry in surficial, diagenetic and low-T metamorphic systems. Coexisting amphiboles increasingly partition delta (super 18) O in the order: hornblende < gedrite < cummingtonite < or = anthophyllite.

X-ray concentration maps of the sectioned diffusion charges showed that double-diffusive convection occurred in the experiments along the direction of constant SiO (sub 2) even though the denser melt was placed below the less dense composition; such double-diffusive fingering instabilities are consistent with predictions of linear stability theory.

Highly mutagenic compounds are known to be formed in meat during the cooking process. Since the discovery of such compounds, many studies have been conducted to evaluate their carcinogenic potential. One of the most mutagenic compounds formed in the cooking of meat is 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ). The recent development of mouse chromosome painting probes expand the capability of evaluating these food mutagens as potential clastogens in vivo. In this paper, we demonstrate the induction of chromosome aberrations in mice chronically exposed to MeIQ in their diet. CDF1 female mice were fed 400 ppm MeIQ beginning at 7 wk of age. At 76 wk of age, five control and eight exposed mice were euthanized. Blood and bone marrow cells were obtained and arrested in metaphase. Whole chromosome painting probes were used for fluorescence in situ hybridization of metaphase cells from blood and bone marrow. MeIQ-exposed mice were found to have a twofold increase in translocations and a 16-fold increase in fragments in their peripheral blood compared with controls. No aberrations were observed in the bone marrow. All organs were examined for the presence of tumours and routine histopathological analysis was performed on all organs as well as any tissue with macroscopic abnormalities. Forestomach and/or liver tumours developed in all but one of the mice fed MeIQ, but no such tumours were observed in the control mice. These data indicate that MeIQ is clastogenic and carcinogenic in vivo..

Repair of these potentially mutagenic or lethal lesions is carried out by apurinic/apyrimidinic (AP) endonucleases. To test current models of AP site recognition, we examined the effects of site-specific DNA structural modifications and an F266A mutation on incision and protein-DNA complex formation by the major human AP endonuclease, Ape. Changing the ring component of the abasic site from a neutral tetrahydrofuran (F) to a positively charged pyrrolidine had only a 4-fold effect on the binding capacity of Ape. A non-polar 4-methylindole base analog opposite F had a <2-fold effect on the incision activity of Ape and the human protein was unable to incise or specifically bind 'bulged' DNA substrates. Mutant Ape F266A protein complexed with F-containing DNA with only a 6-fold reduced affinity relative to wild-type protein. Similar studies are described using Escherichia coli AP endonucleases, exonuclease III and endonuclease IV. The results, in combination with previous findings, indicate that the ring structure of an AP site, the base opposite an AP site, the conformation of AP-DNA prior to protein binding and the F266 residue of Ape are not critical elements in targeted recognition by AP endonucleases.

AN - 80044453; 9685572 AB - The repair of DNA damage protects the genome of the cell from the insults of cancer causing agents. This was originally demonstrated in individuals with the rare genetic disease, xeroderma pigmentosum, the prototype of cancer genes, and subsequently in the relationship of mismatch repair to colon cancer. Recent studies suggest that individuals with less dramatic reductions in the capacity to repair DNA damage are observed at polymorphic frequency and these individuals have an increased susceptibility to several types of cancer. Screening of individuals for DNA sequence variation in the exons of 9 DNA repair genes has resulted in identification of 15 different polymorphic amino acid substitution variants. Although the studies to relate these variants to reduced DNA repair capacity and cancer status have not been completed, the available information is sufficient to suggest that DNA repair genes should be incorporated into molecular epidemiology and cancer susceptibility studies. The availability of molecular epidemiology data presents exciting opportunities for refinement of risk estimation models and identification of individuals at increased risk of disease, with resultant opportunities for effective surveillance and early intervention and treatment. The opportunities to acquire susceptibility data are associated with possible perils for establishment of regulations for permissible exposures to carcinogenic agents and also stigmatization of 'at risk' individuals that may result in decreased access to employment opportunities and health care.

AN - 80042993; 9685691 AB - The dichotomy between the doses at which experimental measurements of genetic effects can be made and the doses to which people are exposed is often different by two or more orders of magnitude. This presents a significant problem when determining the effects of low doses of radiation or chemicals. The solution has usually involved extrapolating the data by curve-fitting or by applying theoretical considerations. Both approaches are unsatisfactory due to uncertainties of the assumptions used in each process. The alternative solution has been to increase the sample size enormously at the lower doses. This is impractical beyond a certain point due to the variation in the spontaneous frequency and the need to quadruple the sample size for a doubling of precision. The development of new methods for measuring stable genetic effects, however, permits a simple and effective approach to this problem: if the genetic events being detected have no effect on survival, i.e., are selectively neutral, then the effects of multiple independent treatments will be additive. If the independent treatments are identical, then the effect of each is easily calculated by dividing the total effect by the number of treatments. Here we report a limited test of this approach using mice. Chromosome aberrations induced in lymphocytes and Dlb-1 mutations induced in the small intestine were measured after daily doses of 0.64, 1.85 or 5.5 cGy 137Cs gamma rays administered for 21, 42 or 63 days. The dose response curve for chromosome translocations obtained in this way, combined with the data from single larger acute doses, shows no evidence for a threshold over a 500-fold dose range. Dlb-1 mutations were increased at each dose and time but the results do not permit reliable extrapolations. The results suggest that translocations might be useful for quantifying the effect of doses below 0.05 cGy and that the effect of dose rate and dose fractionation at much lower doses than reported here could be investigated.

AN - 80038294; 9685706 AB - This review surveys the chemical and biological factors that are correlated with the mutagenic activity of the aromatic and heterocyclic amines. Particular attention is given to the predicted quantum chemical properties of the parent amines and their metabolites. A number of chemical properties have been found to correlate well with measured mutagenic potency, including log P, the energies of the frontier orbitals of the parent amines, and the thermodynamic stability of the nitrenium ion, possibly the ultimate DNA-binding species. These correlations are intriguing clues to the mutagenic activity of the aromatic amines; however, many factors still await final explanation, including the exact mechanisms of the metabolic enzymes, the identity(s) of the ultimate DNA-binding species, the reaction mechanism in the DNA-adduction, the role of sequence context in the covalent and non-covalent binding of the adducts, and the role of DNA repair.

AN - 79997292; 9660962 AB - The phenotypically similar hamster mutants irs1 and irs1SF exhibit high spontaneous chromosome instability and broad-spectrum mutagen sensitivity, including extreme sensitivity to DNA cross-linking agents. The human XRCC2 and XRCC3 genes, which functionally complement irs1 and irs1SF, respectively, were previously mapped in somatic cell hybrids. Characterization of these genes and sequence alignments reveal that XRCC2 and XRCC3 are members of an emerging family of Rad51-related proteins that likely participate in homologous recombination to maintain chromosome stability and repair DNA damage. XRCC3 is shown to interact directly with HsRad51, and like Rad55 and Rad57 in yeast, may cooperate with HsRad51 during recombinational repair. Analysis of the XRCC2 mutation in irs1 implies that XRCC2's function is not essential for viability in cultured hamster cells.

AN - 79969029; 9643579 AB - Whole chromosome painting was used to determine whether the use of different sets of paints would influence results obtained from the analysis of human peripheral blood lymphocytes from 27 healthy unexposed subjects. Painting was also used to determine if aberration frequencies are proportional to the size of selected chromosomes in human lymphocytes irradiated in vitro. The in vitro results showed that the frequencies of radiation-induced stable aberrations (i.e. translocations and insertions) in chromosomes 3, 5 and 6 painted in unique colors are proportional to chromosome size. Aberration frequencies in the normal subjects were measured using two different sets of paints, one set for chromosomes 3, 5 and 6 where each chromosome was labeled in a unique color and one set where chromosomes 1, 2 and 4 were painted in a single color. The frequency of aberrations among chromosomes 1-6 in the population as a whole was also found to be proportional to chromosome size. However, some individual subjects had a distribution of damage that was not proportional to chromosome size due to the presence of clones of abnormal cells. Aberration frequencies measured in chromosomes 3, 5 and 6 as a set were highly correlated with those observed in chromosomes 1, 2 and 4 as a set, after adjusting for the different amounts of the genome that were painted. We also determined whether differences exist in the aberration frequencies measured by two scoring systems: the classical method, where reciprocal exchanges are scored as single events, and PAINT, where each break junction is scored as a single event. The two scoring systems gave highly correlated results for translocations and differed by a constant value (PAINT x 0.58 = classical method). Approximately 27% of translocations were observed to be non-reciprocal due to a failure to detect exchanges involving small amounts of material or to a non-reciprocal exchange mechanism. Our results support the hypothesis that cytogenetic evaluations for biodosimetry can be performed with any one or more of the chromosomes studied here and indicate that the aberration frequency measurements are independent of the scoring system selected for the evaluation. We also present a simple statistical method for identifying subjects that may possess clonal aberrations.

AN - 79950022; 9635883 AB - 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is a mammary carcinogen in female rats and is present in a wide variety of cooked meats. We address here the excretion of PhIP and its metabolites into the breast-milk of lactating rats and the ability of chlorophyllin, a food product derivative with chemopreventive properties, to affect these levels at low PhIP doses. Lactating female F344 rats with suckling pups were orally administered 50, 500 and 1000 ng [14C]PhIP/kg body weight. The excretion of the [14C]PhIP into milk and its distribution among the mammary tissue, liver and blood of the dam, as well as among stomach contents and liver of their suckling pups was measured using accelerator mass spectrometry (AMS). PhIP, PhIP-4'-sulfate, 4'-hydroxy-PhIP, and N2-hydroxy-PhIP-N3-glucuronide were found in the milk at all doses. The chlorophyllin (500 microg/kg) co-administration with PhIP (500 ng/kg) caused increased levels of [14C]PhIP in the milk (32%) and stomach contents (35%) of the pups relative to the animals not receiving chlorophyllin at these low PhIP doses. In contrast, lower [14C]PhIP levels in the chlorophyllin treated animals were observed in the blood (47%) and mammary tissue (68%) of the dam, as well as the pup's liver tissue (37%) compared to the animals receiving only PhIP. Chlorophyllin co-administration resulted in an increased amount of N2-hydroxy-PhIP-N3-glucuronide (42%), increased PhIP (79%) and decreased levels of PhIP-4'-sulphate (77%) relative to the animals not receiving chlorophyllin. These results suggest that PhIP and PhIP metabolites are present in the breast-milk of lactating rats at human dietary PhIP exposures and that PhIP is absorbed by the newborn. Furthermore, these results suggest that other dietary components can affect the dosimetry of PhIP in breast-feeding offspring.

At Lawrence Livermore National Laboratory (LLNL), a methodology termed hydrostratigraphic analysis is employed to divide the complex alluvial sediments beneath LLNL into hydrostratigraphic units (HSUs). HSUs are defined as sedimentary sequences whose permeable layers show evidence of hydraulic communication and interconnection. In contrast, hydraulic communication between HSUs is restricted across HSU boundaries. HSUs are based on a comprehensive analysis and integration of chemical, hydrogeological, geological, geophysical, and aquifer test data. At LLNL, eight HSUs have been identified in the underlying 300 foot thick sequence of unconsolidated sediments. The HSU approach is used to optimize the location of wells associated with the monitoring, hydraulic containment, and systematic cleanup of ground water contaminant plumes and their source areas. Borehole and well locations are based on detailed mapping of higher-permeability sediment distribution, ground water gradients, and contaminant distributions in soil and ground water in each HSU. Understanding the subsurface features that control contaminant flow and transport has enabled LLNL to effectively implement remediation plans, decrease cleanup times, and reduce overall project costs. The significant progress made towards hydraulically controlling and cleaning up the contaminant plumes over the last eight years is clearly evidenced by isoconcentration time series maps, hydraulic capture maps, and mass removal rate plots for each HSU. Hydrostratigraphic analysis is a key tool for demonstrating cost-effective ground water cleanup to DOE, the regulators, and the community.

Site 300 is an 11-square mile Department of Energy experimental test facility and superfund site located in the semi-arid, rugged terrain of the Altamont Hills near Tracy, California. Ground water flow at Site 300 occurs mainly in two distinct aquifer types, alluvial and bedrock. The Quaternary alluvial aquifers are 10-30 feet-thick and consist of sand and gravel deposited in southeast- to northeast-trending canyons that ultimately flow into the San Joaquin Valley. The bedrock aquifers occur in the Miocene Neroly Formation, a 500+ foot-thick, fluvial-lacustrine sequence consisting of interbedded claystone, siltstone, sandstone, and conglomerate. The alluvial aquifers are characterized by high hydraulic conductivity and flow velocity. Ground water flow is controlled by channel geometry and contaminant transport is dominated by advective and dispersive processes due to high flow velocities. In contrast, the bedrock aquifers are characterized by low hydraulic conductivity and low ground water flow velocity. Ground water flow is controlled by bedrock structure and contaminant transport is strongly influenced by diffusive and sorptive processes due to very low flow velocities. Plume migration at the site is influenced by the seasonal interaction between these two flow systems. Evidence demonstrating the interaction between these two flow systems and their impact on trichloroethylene and tritium plumes will be presented to illustrate these concepts.

Site 300 is an 11-square mile Department of Energy explosives test facility and Superfund site located in the semi-arid, rugged terrain of the California Coast Ranges near Tracy, California. The sources for one plume are two unlined landfills containing tritium-bearing debris. Local changes in ground water levels have caused releases of tritium from the landfills to the vadose zone and ground water. The source for the second plume is an explosives testing platform, where tritium has accumulated in the shallow subsurface. Rainfall percolating through the platform carries tritium downward to ground water. Semi-annual tritium activity contour maps and saturated thickness maps from 1985 to 1997 (approximately one tritium half-life) were developed to determine changes in plume locations and total tritium activity. We find that despite releases of tritium to ground water, 1) the locations of the lower tritium-activity contours do not change substantially with time, and 2) the dominant plume attenuation mechanism appears to be radioactive decay.

Experiments were performed at 900 degrees C in the beta -stability field (15 GPa) for 0.5 h and in the beta +gamma stability field (16 GPa) for 11 h using a multianvil apparatus with San Carlos olivine as the starting material. A sample assembly designed to produce non-hydrostatic stress was used. The deformed samples have been characterised using optical and transmission electron microscopy. Remnant olivine contains high densities of mostly c dislocations and deformation occurs by dislocation glide involving the slip systems (010)[001] and (100)[001]. In wadsleyite, dislocations are in a climb configuration which suggests that self diffusion of Si and/or O is much faster in wadsleyite than in olivine at approximately 900 degrees C. Wadsleyite also contains (010) (sub beta ) stacking faults which are interpreted to be growth defects that anneal out with time. During the olivine-wadsleyite transformation, non-hydrostatic stress results in anisotropic reaction textures. Wadsleyite nucleates preferentially on olivine grain boundaries which are oriented at a high angle to the direction of principal compressive stress and/or the growth of wadsleyite occurs preferentially in this direction. Wadsleyite transforms to ringwoodite by two competing mechanisms: (i) coherent intracrystalline nucleation on a dislocations, probably where they intersect (010) (sub beta ) stacking faults, and (ii) partially-coherent nucleation at wadsleyite grain boundaries. Non-hydrostatic stress enhances transformation rates by increasing the density of dislocations which act as nucleation sites for ringwoodite. Although the samples were partially reacted under non-hydrostatic stress, there is no evidence for transformational faulting.

Our goal is to match our computed curves to laboratory measurements of porosity-permeability relationships in real rocks. To achieve this goal we model rock as a dense random pack of identical spherical grains with diagenetic cement deposited in the pore space. The positions of the sphere centers in our numerical model are taken from experimental measurements (the Finney pack). The diagenesis is simulated in various ways: uniform cement deposition on the surface of each grain (uniform growth of the grains); cement deposition at grain contacts; cement deposition away from grain contacts; random filling of the pore spaces; and various combinations of these. Permeability is computed by explicitly modeling Stokes flow in the simulated pore space using a lattice Boltzmann method. Our simulations produce distinctively different porosity-permeability relationships which are characteristic of the cement deposition pattern. The distinctive porosity-permeability relationships found in laboratory measurements of real rocks are matched by certain simulation schemes. Copyright 1998 by the American Geophysical Union.

A simple harmonic analysis of the 12-month seasonal mean precipitation values and a principal component (PC) analysis of the 120 monthly values were carried out. Emphasis is placed on the basic seasonal variation for three subregions: the eastern and central United States and the U.S. west coast. It is vital for GCM simulations to accurately portray the seasonal cycle. The results indicate the following. 1) There are problems for almost all the models in capturing the seasonal variation of the precipitation over the eastern United States. The models typically overemphasize the summer-spring rainfall amounts. The PC analysis indicates that many of the models tend to extend the precipitation regime typical of the central United States too far to the east, resulting in a precipitation maxima occurring in the summer for the eastern region. 2) The seasonal variation of the West Coast is handled with the greatest fidelity. This result cuts across all the models and may be attributable to the fact the SST forcing is specified and common to all the simulations. The common SST forcing is apparently a dominant factor in determining this region's precipitation climatology. 3) On the space scales of the regions selected, there is little consistent evidence that points to any specific model feature as a predictor of model performance. None of the obvious candidates such as horizontal resolution, convective closure schemes, or land surface schemes are reliable discriminators of a model's ability to simulate precipitation. 4) For one smaller subregion centered over Arizona, chosen because of the dominance of the semiannual cycle, there is evidence that increased horizontal resolution has an effect. For this intermountain region the higher-resolution models as a whole do better than the low-resolution models. However, even in this case there is enough variation among the individual simulations to obscure the conclusion that increased horizontal resolution is a necessary or sufficient quality to produce a reliable simulation. 5) The models tend to have less interannual variation than the observations with more variance being explained by the leading (annual cycle) PC, whereas the observations have a less peaked spectrum.

AN - 79836461; 9577754 AB - In vitro uptake of 14C-labeled trichloroethylene (TCE) from dilute (approximately 5-ppb) aqueous solutions into human surgical skin was measured using accelerator mass spectrometry (AMS). We analyzed 105 breast-tissue samples obtained from three subjects, representing 27 separate exposure experiments conducted at approximately 20 degrees C for 0, 1, 5, 15, 30, or 60 min. The AMS data obtained positively correlate with (p approximately 0) and vary significantly nonlinearly with (p = 0.0094) exposure duration. These data are inconsistent (p approximately 0) with predictions made for TCE by a proposed U.S. Environmental Protection Agency (USEPA) dermal-exposure model, even when uncertainties in its recommended parameter values for TCE are considered, but are consistent (p = 0.17) with a 1-compartment model for exposed skin-surface tissue governed in vitro by a maximum effective permeability of K*p = 0.28 cm h-1 (+/- 7.0%) and a first-order rate constant of k1 = 1.2 h-1 (+/- 16%). The apparent compartment depth is estimated to be approximately 40-100 microns, i.e., to comprise much or all of the epidermis. In contrast, the USEPA model implies only negligible TCE penetration beyond SC during a 1-h exposure. The K*p estimate based on the 1-compartment model fit is consistent with estimates for TCE based on in vivo studies, which supports the hypothesis that the USEPA model underpredicts short-term dermal uptake of TCE from water. It is shown that for humans, this fit also implies that normalized total uptake of TCE from water by short-term dermal contact in vivo is predicted to be fK*p, where f is approximately 80% for longer normothermic exposures and approximately 95% during a brief hot shower or bath. This study illustrates the power of AMS to facilitate analyses of contaminant biodistribution and uptake kinetics at very low environmental concentrations.

M., Caldeira, K., 1993. Paleoatmospheric consequences of CO (sub 2) released during early Cenozoic regional metamorphism in the Tethyan orogen. In: Touret, J. L. R., Thompson, A. B. (Guest-Eds.), Fluid-Rock Interaction in the Deeper Continental Lithosphere. Chem. Geol. 108, 201-230.] [Kerrick, D. M., Caldeira, K., 1994a. Metamorphic CO (sub 2) degassing and early Cenozoic paleoclimate. GSA (Geol. Soc. Am.) Today 4, 57-65.]. However, our revised CO (sub 2) mass loss computations for regional metamorphism in the Himalaya-Karakoram belt incorporating recent geochronologic data and revised estimates of the proportion of carbonate source rocks indicate that metamorphic CO (sub 2) degassing from this orogen cannot explain Early Eocene warmth. Widespread pluton-induced hydrothermal flow occurred during the Eocene in the Cordilleran belt of western North America. Synmetamorphic intrusions, which are common in metamorphic belts, may cause significant regional fluid flow. To obtain a representative CO (sub 2) flux from such environments, we computed a CO (sub 2) flux of 1.5X10 (super 12) mol km (super -2) Ma (super -1) from petrologic and geochemical studies of the Paleozoic plutonic-metamorphic belt in New England (northeastern United States). For the 2X10 (super 6) km (super 2) area of Eocene metamorphism in the North American Cordillera, the CO (sub 2) fluxes derived from the New England metamorphic belt yield an area-integrated flux of approximately 3X10 (super 18) mol Ma (super -1) . If a significant fraction of this CO (sub 2) entered the atmosphere, this degassing flux would alone account for Eocene greenhouse global warming. For the Ominica belt within the Cordilleran orogen, a volumetric estimate of the mass of carbonate veins indicates that the consumption of CO (sub 2) by precipitation of carbonate veins may not significantly decrease the amount of CO (sub 2) in fluids that convect to near-surface crustal levels. Compared to other Eocene metamorphic belts, the widespread hydrothermal activity in the North American Cordillera may have been the largest, and most climatically significant, source of metamorphic CO (sub 2) to the Eocene atmosphere. CO (sub 2) degassing by active metamorphism is most significant in extensional regimes of high heat flow. Extensional tectonism and hydrothermal activity in metamorphic belts may have substantially contributed to atmospheric CO (sub 2) content throughout the Phanerozoic. Examples include the Mesozoic circum-Pacific metamorphic belt, and Oligocene-Miocene regional metamorphism in the Himalayan orogen.

The GERM initiative will provide a review of available scientific constraints for: (1) the composition of all major chemical reservoirs of the present-day Earth, from core to atmosphere; (2) present-day fluxes between reservoirs; (3) the Earth's chemical and isotopic evolution since accretion; and (4) the chemical and isotopic evolution of seawater as a record of global tectonics and climate. Even though most of the constraints for the GERM will be drawn from chemical data sets, some data will have to come from other disciplines, such as geophysics, nuclear physics, and cosmochemistry. GERM also includes a diverse chemical and physical data base and computer codes that are useful for our understanding of how the Earth works as a dynamic chemical and physical system. The GERM initiative is developed in an open community discussion on the World Wide Web (http://www-ep.es.llnl.gov/germ/germ-home.html) that is moderated by editors with responsibilities for different reservoirs, fluxes, data bases, and other scientific or technical aspects. These editors have agreed to lay out an initial, strawman GERM for their respective sections and to moderate community discussions leading to a first, preliminary consensus. The development of the GERM began with an initial workshop in Lyon, France in March, 1996. Since then, the GERM has continued to be developed on the Internet, punctuated by workshops and special sessions at professional meetings. A second GERM workshop will be held in La Jolla, CA USA on March 10-13, 1998. Abstract Copyright (1998) Elsevier, B.V.

Both the laboratory and field precipitation rates are dependent on reaction affinity for SiO (sub 2(AmSi)) +2H (sub 2) O = H (sub 4) SiO (sub 4) (AB1). In simple laboratory solutions supersaturated with respect to amorphous silica by a factor less than 1.3 and in the absence of chemical impurities, precipitation rates have a first-order dependence on f(delta G (sub r) ) Rate (sub ppt) ([Si] m (super -2) s (super -1) ) = k (sub ppt) exp (E (sub a) /RT) (1-exp delta G (sub r) /RT) (AB2) where k (sub ppt) = 10 (super -1.9) [Si] m (super -2) s (super -1) and E (sub a) = 61+ or -1 kJ mol (super -1) . In more supersaturated and chemically complex field solutions, amorphous silica precipitation rates have a nonlinear dependence on f(delta G (sub r) ) and may be described by Rate (sub ppt) ([Si] m (super -2) s (super -1) ) = 10 (super -10.00+ or -0.06) (exp delta G (sub r) /RT) (super 4.4+ or -0.3) (AB3) or Rate (sub ppt) ([Si] m (super -2) s (super -1) ) = 10 (super -9.29+ or -0.03) (delta G (sub r) /RT) (super 1.7+ or -0.1) (AB4). The changes in reaction order, form of f(delta G (sub r) , and chemical impurities suggest that the dominant amorphous silica precipitation mechanism changes from elementary reaction control in the simple laboratory experiments to surface defect surface nucleation control in the complex field experiments.

THAA, TCHO and lipids account for 91-99% of the TOC in phytoplankton and zooplankton, 57% of TOC in sediment floc and 18-99% of the TOC in phytoplankton and zooplankton, 57% of TOC in sediment floc and 18-38% of TOC in the sediment. Calculated rate constants are THAA approximately TCHO > TOC approximately TN > lipid indicating their relative reactivities in the sediment during early diagenesis. Delta (super 14) C of organic fractions decreased from the surface plankton to ocean-floor sediment at 4100 m; lower Delta (super 14) C signatures occur in the lipid fraction than in THAA and TCHO fractions, and these differences are attributed to differential decomposition of organic material and sorption and/or biological incorporation of DOC into the sediment.

The most significant changes in the condition of the surface water occurred about 12.5 and 9 ka BP during deglaciation. They were caused by warming and, probably, by water freshening, and they resulted in growth of productivity.

Uncertainty in well water concentration is introduced through complex contaminant migration patterns in the subsurface. Variability is considered in parameters related to individual behavior patterns and biological effects and to groundwater extraction and distribution networks. A joint uncertainty and variability (JUV) analysis is used to generate a two-dimensional distribution or risk surface that spans both transport uncertainty as well as individual variability. Cuts in this distributional surface (fractiles of variability and percentiles of uncertainty) are presented and discussed. Comparisons with alternative approaches based upon deterministic transport models are also made. In addition, important distinctions are made between the case where household water is derived from the nearest well and the case where household water is mixed from many wells in a distribution system.

The data are three-component broadband seismograms recorded by the 1991-1992 IRIS-PASSCAL (Incorporated Research Institutions for Seismology-Program for Array Seismic Studies of the Continental Lithosphere) Tibetan Plateau Experiment and Global Seismic Network stations in the region. The Qiangtang Terrane has thick crust (65 + or - 5 km) with P and S wave velocities of 6.1-6.3 and 3.34-3.43 km/s, respectively, yielding an anomalously high crustal Poisson's ratio of 0.29+ or -0.02. Seismic velocities of the upper mantle of the Qiangtang Terrane are normal for P waves and slow for S waves (8.10 and 4.35-4.41 km/s, respectively) with a high mantle Poisson's ratio of 0.29+ or -0.01. Attenuation in the crust and upper mantle is high (Q (sub P ) = 100-200 and Q (sub S ) = 44-89). Modeling of the broadband P waveforms suggests that a decrease in mantle velocity occurs at about 160 km depth in the mantle; however, this is not unambiguously supported by the data and modeling. The crust and uppermost mantle of the Qiangtang Terrane probably contains partial melt based on the high Poisson's ratio, low shear wave velocities, and low Q. The absence of high-frequency S (sub n) and the presence of volcanism of mantle lithospheric origin support the presence of partial melt. Crustal and uppermost mantle structure in the Qiangtang Terrane is different from that for the Lhasa Terrane (immediately to the south) based on results of our previous studies. The average crustal P and S wave velocities are 4% faster and 2% slower, respectively, in the Qiangtang Terrane relative to the Lhasa Terrane. This yields a significant difference in the crustal Poisson's ratio with values of 0.29 for the Qiangtang Terrane and 0.25 for the Lhasa Terrane. Differences in the uppermost mantle P and S wave velocities and Poisson's ratios of these two adjacent terranes cannot be explained by temperature differences alone. Using the mantle temperature estimates of McNamara et al.. [1997] we suggest that partial melt of an ultramafic composition beneath the Qiangtang Terrane fits the velocity and Poisson's ratio estimates. Copyright 1998 by the American Geophysical Union.

Pilot-plant and modeling results are tools in the analysis. The conversion is carried out in two major process steps. The first or pre-treatment step is based on pyrolysis and results in an intermediate product containing approximately 90% of the primary feed in a suitable physical form for the second step. This second step is Texaco's high-temperature, high-pressure gasifier which is based on partial oxidation and converts the organic components to synthesis gas (CO and H sub(2)). Total thermal conversion efficiency for waste to hydrogen is found to be a strong function of feedstock quality. For typical MSW feedstocks, an efficiency of 40-50% is predicted for an integrated process. Fossil-fuel feedstocks such as waste plastics and scrap tires result in efficiencies of the order 60-70%. The cost of produced hydrogen is approximately $15/GJ for typical MSW with a tipping fee of $50/ton, but drops to $6/ton for high-plastics waste that carry a tipping fee of $100/ton.

As sea ice forms, salt is rejected, locally increasing surface sea-water density. This dense water can sink to the pycnocline at the base of the mixed-layer. Previous studies have not considered the impact of this subgrid-scale process on transient tracers in the ocean. To assess the potential importance of this process to the oceanic absorption of atmospheric gases, we performed two idealized simulations: a Control simulation in which salt rejected during sea-ice formation is placed in the model's 25 m thick surface layer; and a Test simulation in which salt rejected during sea-ice formation is distributed uniformly through the upper 160 m beneath the forming sea ice. Our treatment of rejected salt is highly idealized, and is intended to demonstrate the need for a physically-based parameterization of subgrid-scale convection for use in ocean general circulation models that takes into account the subgrid-scale heterogeneity of surface buoyancy forcing. Distributing rejected salt more deeply during periods of ice formation helps to maintain vertical density gradients, inhibiting grid-scale convection, especially in the Southern Ocean. This greatly diminishes simulated ocean uptake of CFC-11, and generally improves simulated CFC-11 and salinity fields. The modeled global ocean inventory of CFC-11 for year 1990 is about 30% lower, and modeled column inventories in the Southern Ocean are up to 90% lower, in our Test simulation relative to our Control simulation. We infer that a more detailed treatment of subgrid-scale processes occurring beneath sea ice may diminish simulated oceanic absorption of anthropogenic CO sub(2), especially in the Southern Ocean.

Comparisons were made between plants growing in an atmosphere naturally enriched with CO sub(2) ( approximately 790 mu mol mol super(-1)) near the CO sub(2) spring and plants of the same species growing in adjacent areas exposed to ambient CO sub(2) concentrations ( approximately 360 mu mol mol super(-1)). Nardus stricta growing near the spring exhibited earlier senescence and reductions in photosynthetic capacity ( approximately 25%), Rubisco content ( approximately 26%), Rubisco activity ( approximately 40%), Rubisco activation state ( approximately 23%), chlorophyll content ( approximately 33%) and leaf area index ( approximately 22%) compared with plants growing away from the spring. The potential positive effects of elevated [CO sub(2)] on grassland ecosystems in Iceland are likely to be reduced by strong down-regulation in the photosynthetic apparatus of the abundant N. stricta species.

The SSCD experiment consisted of a west-east profile across the Sierra Nevada at approximately 36.5 degrees N and a north-south profile extending the length of Owens Valley, located eastward of the Sierran topographic crest. Two-dimensional finite-difference travel-time inversion of P (sub g) and P (sub n) arrivals resolves upper-crustal velocities of 6.0 to 6.4 km s (super -1) within the Sierran Batholith and Basin and Range, an upper-crustal west-dipping wedge of higher velocities (6.8-7.2 km s (super -1) ) consistent with ophiolitic material underlying the Great Valley sedimentary sequence, and higher velocities in the lower crust beneath the Basin and Range (6.8-7.0 km s (super -1) ) than those beneath the Sierran Batholith (6.6 km s (super -1) ). Low average P (sub n) velocities (7.6-7.9 km s (super -1) ) and a laminated transitional Moho imaged beneath the Sierran Batholith also differ from the higher P (sub n) velocities (7.9-8.0 km s (super -1) ) and sharp first-order Moho observed beneath the Basin and Range. The crust decreases in thickness both westward of the root to 28-34 km beneath the Great Valley and eastward to 35 km beneath the highest Sierran topography and decreases further to 27-30 km beneath the Basin and Range. Crustal thickness also appears to increase southeast to northwest from 29-30 km beneath the Garlock Fault in the south to 38-40 km beneath the north end of Chalfant Valley. Juxtaposition of the crustal model with previous P-wave tomography models of the southernmost Sierra Nevada upper-mantle reveal that the thickest Sierran crust on the west-east profile overlies a pronounced upper-mantle high-velocity anomaly (+5%), whereas the region of laminated Moho overlies a flanking upper-mantle low-velocity region (-3%). The upper-mantle velocity anomalies, relatively low P (sub n) , and relatively flat Moho, observed beneath the Sierran crest suggest that the recent uplift of the Sierra Nevada is due to asthenospheric flow and/or lithospheric thinning beneath the southeastern Sierra Nevada and Basin and Range.

At Hill Air Force Base in Utah, a free-product DNAPL plume (consisting predominantly of TCE) is pooled in water-wet soil on a thick clay aquitard. Groundwater pumping at Operable Unit 2 (OU 2) began in 1994; to date, over 30,000 gallons of DNAPL have been recovered from the site. From September, 1994 through September, 1995, changes in the basin during DNAPL pumping were monitored using fiber optic chemical sensors, neutron logs and electrical resistance tomography (ERT). Fiber optic sensors and neutron logs verify the presence of DNAPL in the vicinity of three boreholes which form a cross section from the perimeter of the basin to its center. Cross borehole ERT images the changes in formation electrical properties due to the removal of DNAPL, extending the understanding of DNAPL removal between the boreholes. During pumping, electrical resistivities decreased; we suggest that these decreases are directly caused by the reduction in DNAPL. During ground water pumping, water with relatively low resistivity replaces some of the DNAPL pockets as the highly insulating DNAPL is removed. The results suggest that, as DNAPL is pumped from a nearby well, product slowly drains along the top of an aquitard and into the pump well, where it collects.

The results indicated that alloys 825, G-3, and G-30 suffered from pitting and crevice corrosion in all tested environments.

AN - 79791894; 9541638 AB - Recently, we reported that 6 of 84 (7.1%) hprt mutants arising in in vitro malathion-treated human T-lymphocytes were characterized by specific genomic deletions in a 125-bp region of exon 3 (Pluth et al., Cancer Research 56 (1996) 2393-2399. We have now extended study to determine whether additional differences in molecular spectrum at a basepair level exist between control and malathion-treated mutations, and investigated whether there is evidence to support the hypothesis that malathion is an alkylating agent. We analyzed 101 hprt mutants (24 from control and 77 from treated cultures) isolated form six in vitro malathion exposures of T-lymphocytes from four healthy male donors. Analysis consisted of: Southern blotting, genomic multiplex PCR, genomic DNA sequencing and reverse transcription of PCR amplification (RT/PCR) and sequencing of the cDNA product. Mutations at several basepair sites were frequent after malathion exposure and were isolated from treated cells from at least two different individuals. Using a human hprt mutation database for comparison, the frequency of mutations at one of these sites (basepair 134) was found to be significantly elevated in the malathion-treated cell (p < 0.0005). Hprt mutations in malathion-treated cells arose preferentially at G:C basepairs, which is consistent with earlier reports that malathion alkylates guanine nucleotides. Assessing molecular changes at both genomic and cDNA levels in the same mutants revealed that many small, partial exon deletions (< 20 bp) in genomic DNA were often represented in the cDNA at the loss of one or more exons. In addition, It was noted that identical genomic mutations can result in different cDNA products in different T-cell isolates. These observations affirm the importance of genomic sequence analysis in combination with RT/PCR for a more accurate definition of the mutation spectrum.

The results compare very well with wet-chemical and Mossbauer spectroscopic analyses of the same samples. Areas of 10X20 mu m have been measured successfully, and the results demonstrate that both zoning of Fe (super 3+) and the effect of oxide inclusions on bulk analyses can be quantified. Such sample heterogeneity cannot be detected by conventional bulk analytical techniques. The ability to measure Fe (super 3+) /Sigma Fe with spatial resolution comparable to that of the electron probe further enhances the importance of microbeam techniques in the earth and planetary sciences. Direct measurements of elemental oxidation states that can constrain oxidation-reduction processes are now possible with close to the spatial resolution of traditional compositional analyses derived from electron, or ion, beam and optical microscopic techniques. New, more intense, synchrotron sources such as the Advanced Photon Source at Argonne National Laboratory, are becoming available for analyses of 1-10 mu m areas.

On the basis of our own mapping and earlier investigations in the area, the Late Cenozoic southern Tian Shan thrust belt may be divided into four segments based on their style of deformation. From west to east, they are (1) Kashi-Aksu imbricate thrust system, (2) the Baicheng-Kuche fold and thrust system, (3) the Korla right-slip transfer system, and (4) the Lop-Nor thrust system. The westernmost Kashi-Aksu system is characterized by the occurrence of evenly spaced (12-15 km) imbricate thrusts. The Baicheng-Kuche and Korla systems are expressed by a major north dipping thrust (the Kuche thrust) that changes its strike eastward to become a NW striking oblique thrust ramp (the Korla transfer zone). The Lop Nor system in the eastern-most part of the southern Chinese Tian Shan consists of widely spaced thrusts, all involved with basement rocks. Geologic mapping and cross-section construction suggest that at least 20-40 km of crustal shortening with a horizontal shortening strain of 20-30% has occurred in the southern Chinese Tian Shan during the late Cenozoic. These estimates are minimum because of both conservative extrapolation of the thrust geometries and partial coverage of the thrust belt by the cross sections. The timing of initial thrusting is best constrained in the Kuche basin where crustal shortening may have occurred at 21-24 Ma, the time of a major facies transition between lacusrine and braided-fluvial sequences constrained in general by biostratigraphy and in detail by magnetostratigraphy. This estimate represents only a minimum age, as development of thrusts in the southern Chinese Tian Shan may have propagated southward toward the foreland. Thus the sedimentary record only represents the southernmost and therefore youngest phase of thrusting. If our estimate of timing for the thrust initiation (21-24 Ma) is correct, using the estimated magnitude of shortening (20-40 km) and shortening strain (20-30%), the averaged rates of late Cenozoic horizontal slip and shortening strain are 1-1.9 mm yr (super -1) and 2.9-4.5 X 10 (super -16) s (super -1) , respectively. Our reconnaissance (super 40) Ar/ (super 39) Ar thermochronological analysis in conjunction with earlier published results of apatite fission track analysis by other workers in the Chinese Tian Shan suggests that the magnitude of Cenozoic denudation is no more than 10 km, most likely less than 5 km. We demonstrate via a simple Airy-isostasy model that when the thermal effect on changes in surface elevation is negligible, determination of the spatial distribution and temporal variation of both horizontal shortening strain and denudation becomes a key to reconstructing the elevation history of the Tian Shan. Using this simple model, the loosely constrained magnitude of crustal-shortening strain and denudation in the southern Chinese Tian Shan implies that it may have been elevated 1.0-2.0 km since the onset of Cenozoic thrusting.

The procedure consists of two sequential steps: (i) Prediction of mean flow and turbulence fields via a turbulent flow model; and, (ii) Employment of the calculated flow and turbulence fields to drive a Lagrangian stochastic particle model. Two flow scenarios are used as input to a Lagrangian model; the scenarios assume neutral atmospheric conditions and incoming winds that are from 270 and 240 degree . The problem configuration for the first calculation is based on an earlier transport and diffusion simulation that employed an existing particle-in-cell flux-gradient dispersion model. The second simulation is used to demonstrate the strong spatial variations that the concentration field exhibit within the highly complex separation zones of building wakes. The relationship between concentration levels and toxic load are discussed for the case of a chemical spill.

Nevertheless, the ecological life history of most tropical trees is unknown and even the ages of the largest trees remain to be determined. Tree ages are typically measured by counting annual rings, but in tropical forests rings can be non-existent, annual or irregular. In the absence of annual rings, super(14)C dating is the only way to determine the age of a tree directly. We have super(14)C-dated twenty large, emergent trees from a central Amazon rain forest and find that, contrary to conventional views, trees in these forests can be more than 1,400 years old.

AN - 79794252; 9544190 AB - A multicolor fluorescence in situ hybridization (FISH) method was developed to detect aneuploidy and diploidy in epididymal sperm of rats using DNA probes specific for chromosomes 4 and Y. Fourteen healthy young-adult rats from three strains were evaluated: inbred Fisher 344/N/ehs, outbred Sprague-Dawley, and outbred WU Wistar/CPB. The hybridization efficiency of the FISH procedure was > 99.9%, the sex-ratio in sperm was approximately 1 as expected, and there was no significant variation among two independent scorers. No significant variations were detected within or among strains in the frequencies of sperm disomy for chromosome 4 (1-6.5 per 10,000 cell per animal) or the Y chromosome (0-2.5 per 10,000 cells per animal). There was a trend toward increased variation among Wistar rats. The frequencies of sperm-carrying hyper- and hypohaploidy for chromosome 4 were similar, suggesting a symmetrical mechanism of chromosome gain and loss during meiosis. The frequencies of Y-Y-4-4 sperm, which represent genomic meiosis II errors, did not differ significantly across strains (0.1-0.7 per 10,000 cells per strain). This FISH method for detecting aneuploidy in rat epididymal sperm provides a promising interspecies biomarker of male germ cell aneuploidy and introduces the rat as an animal model for investigating the heritable risk to offspring associated with paternal genotype, physiology, and exposure to environmental mutagens. There appear to be no significant differences among young healthy rats, mice, and men in the baseline frequencies of sperm with Y chromosomal disomy, the only chromosome for which data currently exists for all three species.

Measurements on young and modern straths show no significant ingrowth of (super 10) Be and (super 26) Al, implying that strath exposure ages closely approximate their abandonment age. Strath exposure ages range up to 65 ka and increase with height above the river. The straths can be divided into two groups: low straths dated at about 7 ka, which yield very rapid bedrock incision rates (9-12 m/ka), and high straths >7 ka in age, which yield somewhat slower incision rates (1-6 m/ka). Incision rates for both groups increase by approximately 1-3 m/ka downstream toward an active reverse fault, the Raikot fault, that forms the western border of the Nanga Parbat-Haramosh massif (NPHM). The downstream increases in incision rates for the low straths mimic downstream increases in the modern gradient, suggesting that bedrock incision rates have been proportional to stream power over the last 7 ka. Gradient increases are probably the result of the creation of knickpoints by bedrock uplift along the Raikot fault. The longitudinal profile and steep gorge of the Indus River in the study area indicate that bedrock incision appears to keep pace with differential vertical motions between the NPHM and surrounding regions. Thus, the 1-3 m/ka difference in incision rates likely reflects the differential bedrock uplift rate between the NPHM and the Skardu Basin. The differential incision rate is consistent with differential exhumation rates obtained from apatite fission track ages assuming geotherms of < or =80-90 degrees C/km in the NPHM and 35 degrees C/km in the Skardu Basin. This relation suggests that rapid bedrock incision of at least 1-3 m/ka has persisted within the NPHM for the last 0.5 Ma. The acceleration of incision rates throughout the study area since 15 ka is likely to be a climatic signal that records an increase in the discharge and/or sediment load of the Indus River in the study area related to deglaciation of the surrounding terrane.

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 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 simulated precipitation which can introduce further complexity in climate simulations.

As surface parameterizations include more processes, they have moved from being subroutines of GCMs to independent schemes which can also be applied for other purposes. This evolution has raised the problem within climate modeling groups of coupling these schemes to GCMs in a simple and flexible way. As LSS reaches a larger independence, a general interface is needed to enable exchange within the community. This paper discusses the tasks LSS have to fulfill when coupled to a GCM after a review of the current state of the art and the likely future evolutions of both components. The numerical schemes used for the processes which couple the land surfaces to the atmosphere are reviewed to ensure that the interface can be applied to all LSS and GCMs after only minor changes.

The outcrops were chosen based on lithology, distance from late glacial maximum terminus, landscape position, lack of till and loess cover, presence of striae, chattermarks, grooves, and ventifaction features. We have acquired preliminary data for 12 of the samples and use the production rate estimates of Nishiizumi et al. (1989) to calculate model ages, although recent work suggests that these production rates may be as much as 20% too high and thus our age estimates may be low by a similar percentage. Stated uncertainties in exposure ages propagate analytic precision (4-6%) along with a 20% uncertainty in production rates. Any shielding by snow cover would also cause our model ages to be underestimates. Quartzite samples from the Baraboo Hills, 10 km within the late glacial maximum position, yield 6 model ages ranging from 34.3+ or -7.3 to 73.5+ or -15.2 ky, indicating inheritance from prior exposure. Quartzite samples 60 km behind the terminus near Waterloo, Wisconsin yield 10 model ages from 13.5+ or -2.9 to 19.1+ or -4.1 ky (mean of 4 samples with replicates, 15.8+ or -0.9 ky and 15.2+ or -0.7 ky for 10-Be and 26-Al model ages respectively). Granite samples from Cactus Rock, WI, about 100 km behind the terminus, yield 4 model ages from 14.0+ or -3.0 to 14.9+ or -3.1 ky (mean of 4 samples 14.5+ or -0.2 ky for 10-Be model ages). These results suggest deglaciation of the Green Bay lobe occurred sometime before 15.5 (super 10) Be/ (super 26) Al years BP. The differences between model ages at Waterloo (60 km from terminus) and Cactus Rock (100 km from terminus) suggest that at least 1000 years separated ice maximum and the readvance and deposition of the clayey Kewaunee Till. These data suggest that it is unlikely that the Green Bay lobe was at its maximum as late as 15,000 calendar years BP.

The solubility data were regressed using the method of Clarke and Glew (1966) to calculate the partial molal thermodynamic quantities of the dissolution reactions: delta G, delta H, delta S, and delta Cp. Calculated values for these quantities at 298 K for TCE are: delta G = 11.282 (+ or -.003) kJ/mol, delta H = -3.35 (+ or -.07) kJ/mol, delta S = -49.07 (+ or -.24) J/mol-K, and delta Cp = 385.2 (+ or -3.4) J/mol-K. Calculated values for these quantities at 298 K for PCE are: delta G = 15.80 (+ or -.04) kJ/mol, delta H = -1.79 (+ or -.58) kJ/mol, delta S = -59.00 (+ or -1.96) J/mol-K, and delta Cp = 354.6 (+ or -8.6) J/mol-K. These data may be used to calculate the solubility of TCE and PCE at any temperature of interest.

Because crystallization is, first and foremost, a phase transition, it is critical to separate the roles of kinetics and equilibrium thermodynamics in controlling crystallization rates and resultant mineral morphologies, while also quantifying the energetics associated with growth in both the pure and organically mediated systems. Current understanding of parameters governing calcite growth is inferred from indirect methods that monitor bulk solution composition.We test theoretical model predictions by directly determining fundamental growth parameters in an in situ AFM investigation of calcite crystallization. Using finely-controlled solution saturation states, migration rates of monomolecular steps were measured on dislocation-induced growth hillocks. We determined the dependence of step speed on step length as well as the dependence of critical step length, step speed, and terrace width on supersaturation, s. We show that once the critical length, lc, is reached, the step speed increases to its final value at a length which is short compared to predictions from free energy considerations. Thus, the Gibbs-Thomson effect is smaller than expected. This means that classical models predict a growth rate that is slower than measurements by a factor of two. As expected from free energy considerations, lc exhibits the linear dependence on s-1 as predicted by theory. However, the nonequivalence of positive and negative step directions yields two lc(s) relationships and give surface free energies of 595 and 736 erg cm-2, respectively. For both step directions, the value of lc goes to zero at finite s demonstrating that calcite undergoes kinetic roughening at s = 1.7. Introduction of aspartic acid, an active component in biomineralizing systems, dramatically affects growth morphology and alters the magnitude of the thermodynamic parameters. These results provide the foundation for an emerging physical picture of biomineralization.

Our findings allow us to: 1) establish the age of offset fans and calculate slip rates along the Fish Springs fault and 2) compare relative and numerical dating techniques.The Fish Springs fault, associated with the right lateral Owens Valley Fault Zone, has displaced a cinder cone and multiple debris fan surfaces vertically, leaving a record of progressive deformation over the late Quaternary. Martel et al. (1987) established the age of the cinder cone (314+ or -36 ka, 2s), the displacement of the 3 fan surfaces and cinder cone, and the approximate ages of the fan surfaces by correlating them with the assumed timing of local glaciations. We used the Profile Development Index (PDI) of Harden (1982) to quantify soil development in 11 backhoe trenches on 3 fans. PDI values rise with increasing fan age as estimated by relative weathering of fan surfaces, cross-cutting relationships, and separation of tectonically offset surfaces. However, we could not assign numerical ages to fan surfaces based on PDI values because existing soil PDI values of known age are lacking in Owens Valley. Differences in geomorphic surface characteristics preclude application of PDI calibrations developed in other, climatically similar locations. Comparison of soil development with cosmogenic fan surface age estimates and other relative weathering data (i.e. boulder weathering) provides valuable information on late Quaternary soil formation rates in Owens Valley. Despite difficulties assigning independent ages to the fans based on soil development, interpretations of relative weathering data concur with Martel's proposed glacial origins for fan surfaces. From these relations, a long term vertical displacement rate of approximately 0.24 mm/yr of vertical slip is implied, as calculated by Martel et al. (1989), similar to the rate calculated using cosmogenic estimates of fans surface age. (See abstract this meeting by Bierman et al.).

Inorganic and organic compounds are believed to play various roles as impurities in the processes of biomineralization, but their effect on growth kinetics and resultant growth morphology is not understood. Advances in our ability to unravel biologically-induced mineralization by microscopic in situ observation have rejuvenated cross-disciplinary interests in understanding how microbes and higher organisms synthesize minerals at very near equilibrium conditions. This work quantifies relationships between solution supersaturation and step migration rates on the (104) calcite surface using in situ Fluid Cell AFM and shows how to control rates of growth that are highly specific to crystallographic direction to produce unique growth geometries through perturbations in microscopic kinetics. At very near equilibrium, the kinetics of growth produces morphologies that express a dramatically reversed symmetry and a novel isotropic structure for this anisotropic material. Comparisons of our kinetic data with classical theory suggest these effects are due to minute impurities that impact rates of growth by imposing a kinetic "dead zone" on positive steps while negative steps continue to migrate at a modified rate. This behavior is analogous to the effect we also find for aspartate, a recognized growth modifier and constituent in macromolecules associated with biomineralization. The results demonstrate the importance of microscopic kinetics in controlling morphology and the sensitivity to small differences in solution chemistry. Calcite expresses unique forms when chemical equilibrium is carefully controlled to achieve a regime where individual steps assume atypical growth kinetics without the introduction of complex templates. Perhaps organisms use less energetically costly mechanisms to direct morphology during the postnucleation growth phase of biomineral formation.

The fans surfaces are offset (os) varying amounts by the Fish Springs Fault, within the Owens Valley Fault Zone. Our measurements were made in quartz separated from 33 granite and granodiorite debris-flow transported boulders cropping out on fan surfaces and in boulder levees. Measured (super 10) Be and (super 26) Al abundances and resulting age estimates are well correlated, generating r (super 2) values of 0.99. Regression analysis indicates (super 26) Al/ (super 10) Be for this data set (n = 34) is 6.12+ or -0.11 (68% CI), consistent with prior estimates. Replicate samples from the top surface of boulder FSF-V have statistically inseparable (super 10) Be abundances (0.189+ or -0.009 and 0.181+ or -0.012 M atoms/g, standard deviation) and (super 26) Al abundances (1.241+ or -0.063 and 1.176+ or -0.057 M atoms/g, standard deviation) demonstrating the reproducibility of our analyses. Model ages are calculated using production rate estimates of Nishiizumi et al. (1989). Four of the five fan surfaces have cosmogenically distinct ages. Eight boulders cropping out on the oldest fan surface (os = 31 m), have an average model exposure age of 108.7+ or -11.8 ky. Three of four boulders on a fan surface offset >3 m have an average model exposure age of 14.4+ or -0.7 ky. Six boulders on a fan surface offset 3.3 m have an averae model exposure age of 12.8+ or -1.0 ky and four boulders on a fan surface offset 1.1 m have an average model exposure age of 8.0+ or -1.8 ky. Considered along with the Fish Springs cinder cone (os = 78m, Ar age = 314 ky), we calculate a long-term displacement rate of 0.25 mm/yr. The linearity of the age/displacement data (r (super 2) = 0.997) suggests that faulting rates have been constant, within the resolution of our method, over the last 300 ky.

These methods provide quantitative results for groundwater recharge rates, groundwater residence times, and the extent of mixing with ambient basin groundwater. Simultaneous determination of various water quality parameters, including total organic carbon, nitrate, major and trace metals, pathogens, and some organic compounds including methyl tert butyl ether (MTBE; a gasoline additive) allows characterization of the fate of these compounds during infiltration and subsurface flow. In an effort to prevent seawater intrusion, and to augment water supply, approximately 40 billion liters of water per year is artificially recharged through surface spreading ponds and an adjacent creek in recharge facilities of an East Bay water district. Production wells are located 500 to 800 m downgradient. Groundwater ages were determined for several production wells by the tritium-helium method and give mean ages of 3 to 30 years, and show a pattern of increasing age with depth. In addition, a series of isotopically enriched xenon isotope tracers were introduced into spreading ponds and monitored weekly in downgradient wells. An initial pulse of highly diluted tracer arrived very quickly (corresponding to a groundwater velocity of 2700 m/yr.) and suggests a highly dispersive medium, and high hydraulic conductivity for basin sediments (given the low hydraulic gradient prevalent during the course of the study). The bulk of the tracer traveled more slowly, consistent with mean residence times of a few years, as indicated by groundwater ages. Improvement to water quality through groundwater recharge is indicated by elimination of male-specific coliphage, a large reduction in total organic carbon, and a reduction in some trace metals including Al, Fe, Sb, U, and V. Nitrate levels decrease slightly during recharge, while total dissolved solids levels increase slightly. MTBE is ubiquitous at very low levels in surface water (hundreds of ppt) and groundwater (tens of ppt), due to atmospheric deposition and runoff. Significantly lower levels of MTBE detected in somewhat older water may be due to dilution with water recharged before the time of increased use of MTBE as a gasoline additive.

Using in situ-produced cosmogenic 10-Be and 26-Al in quartz extracted from sediment and bedrock, we have estimated long-term, time-integrated rates of erosion (37.5+ or -3.7 m/My) in Yuma Wash Drainage Basin (190 km (super 2) ), Yuma Proving Grounds, AZ. A detailed study of a 7.5 km (super 2) sub-drainage gives erosion rates of (28.8+ or -1.2 m/My) indicating that erosion rates of individual sub-basins may be significantly different than the basin-wide average of all sub-basins. Our data also show no significant relationship between isotopic concentration and sediment particle size; however, isotope abundances in coarser particle size fractions appear more variable than finer fractions, most likely due to fewer particles per unit weight.Isotopic signatures of individual geomorphic "compartments" (bedrock, hillslope colluvium, alluvial fans and terraces, and stream channel sediments) can be used to indicate sediment source areas and degree of sediment mixing within a basin. Resistant bedrock uplands have relatively high isotopic concentrations (2.7+ or -0.15X10 (super 5) atoms/g), while downstream in the basin, sediments have lower isotopic concentrations (1.26+ or -0.08X10 (super 5) atoms/g) suggesting mixing of high-concentration bedrock-derived material with lower-concentration material from weathering of bedrock beneath the hillslope colluvium. The compartmental isotopic signatures can be used to support the assumption that drainage networks are a good integrator of sediment and therefore isotopic concentrations of the material throughout the drainage basin. We believe that erosion rates determined from stream channel sediments may give better estimates of basin-wide erosion rates than those from bedrock outcrops, which represent the most erosion-resistant surfaces within a basin.

The fault zone is marked by a spectacular approximately 40 degrees W-dipping fault scarp exhibiting up to 1.2 km of topographic relief. Footwall rocks, which reach elevations over 6 km, are comprised of the Cordillera Blanca batholith (concordant U-Pb zircon age of 8.2 Ma), the mylonitized western edge of the batholith, and Jurassic metamorphic rocks. Hanging wall rocks, which lie at approximately 3 km within the intercordilleran Callejon de Huaylas basin, include Tertiary volcanic and sedimentary rocks. Fault rocks record a retrograde deformation history spanning the ductile-to-brittle transition. Microstructures within mylonites show predominantly sinistral-oblique shear under greenschist facies conditions; mylonites are overprinted by chlorite-breccia, cataclasite and pseudotachylyte. West of the mylonitic front, Pleistocene-to-Holocene glacial deposits and alluvial fans are cut by active brittle normal faults. We propose that the Cordillera Blanca fault is a deep-seated detachment fault (Cordillera Blanca detachment: CBD) which developed post-emplacement of the Cordillera Blanca batholith. Uplift/exhumation of lower plate rocks along the CBD is significant, elegantly documented by the presence of young (8.2 Ma), approximately 3 kb batholithic rocks 6 km above sea level. The extreme footwall topography coupled with low basinal sedimentation indicates that footwall uplift greatly exceeds basin subsidence. (super 40) Ar/ (super 39) Ar cooling ages from muscovite within the fault zone (Petford and Atherton 1992) and cosmogenic radionuclide dating of offset Pleistocene moraines indicate post-Miocene uplift rates of approximately 3-4 mm/yr. Significant uplift probably occurred in the Pliocene during a well-documented phase of roughly arc-normal extension (Mercier et al. 1992). Nonetheless, the moderate dip of the master fault and the relatively narrow width of the Callejon de Huaylas basin suggest that the detachment is an incipient crustal feature. The dominant kinematic framework of the Cordillera Blanca thus switched from transcurrent faulting in the late Miocene (sinistral strike-slip: McNulty et al. 1998) to an extensional system from Pliocene-to-Recent (CBD). The late Miocene-to-Recent evolution of the Cordillera Blanca reflects both oblique Nazca-South American plate convergence (sinistral strike-slip kinematics) and crustal thickening-induced extension (normal faulting). The Cordillera Blanca provides an exceptional example of crustal detachment, extension and batholith unroofing within young thick crust above an active subduction system.

Independent evaluations of the Cariaco Basin calendar and (super 14) C chronologies were based on the agreement of varve ages with the GISP2 ice core layer chronology for similar high-resolution paleoclimate records, in addition to (super 14) C age agreement with terrestrial (super 14) C dates, even during large climatic changes. These assessments indicate that the Cariaco Basin (super 14) C reservoir age remained stable throughout the Younger Dryas and late Allerod climatic events and that the varve and (super 14) C chronologies provide an accurate alternative to existing calibrations based on coral U/Th dates. The Cariaco Basin calibration generally agrees with coral-derived calibrations but is more continuous and resolves century-scale details of (super 14) C change not seen in the coral records. (super 14) C plateaus can be identified at 9.6, 11.4, and 11.7 (super 14) C ka BP, in addition to a large, sloping "plateau" during the Younger Dryas ( approximately 10 to 11 (super 14) C ka BP). Accounting for features such as these is crucial to determining the relative timing and rates of change during abrupt global climate changes of the last deglaciation.

After the first 40 days of heating, highly variable amounts of moisture were reported on the floor and crown of the observation drift (OD) near the bulkhead that separates it from the heated drift (HD). Within the HD, the relative humidity (RH), after steadily decreasing from 30% to 15% during the first 10 days of heating, began to fluctuate between 10% and 25%. The temperature (T) within the HD has risen monotonically since the heaters were energized. Pre-test model calculations predicted a monotonic decrease in RH accompanying a monotonic increase in T. Close examination of other data collected revealed that the RH fluctuations were strongly, but inversely, correlated with barometric pressure fluctuations, and that the amount of moisture in the OD increased with RH levels in the HD. During a falling barometer, hot moist air leaks around the bulkhead from the HD to the OD, where much of the moisture condenses at the cooler T in the OD. During a rising barometer, air flows from the OD to the HD. When this air is heated within the HD, its RH drops. The model used for pre-test calculations with the NUFT code was modified by imposing a variable pressure boundary condition (BC) in place of a constant gas pressure BC. Preliminary results with a sinusoidal pressure BC produced a fluctuating RH, in qualitative agreement with the field data. Although the measured RH has remained well below the critical threshold value of about 85% that accelerates moist air corrosion, the unexpected fluctuations caused some concern that thermal-hydrologic codes used by the Yucca Mountain Project might have failed to include potentially important processes. It is now clear that the models available produce results in good agreement with experiment when the appropriate BCs are used. This experience shows why field experiments are necessary for testing models, and why models are needed for designing and analyzing experiments.

As far as we are aware, Am has not been reported previously in fossil bone and neither Gla nor Am (super 14) C values have been measured previously. Interest in Gla, an amino acid found in the non-collagen proteins osteocalcin and matrix Gla-protein (MGP), proceeds from the suggestion that it may be preferentially retained and more resistant to diagenetic contamination affecting (super 14) C values in bones exhibiting low and trace amounts of collagen. Our data do not support these suggestions. The suite of bones examined showed a general tendency for total amino acid and Gla concentrations to decrease in concert. Even for bones retaining significant amounts of collagen, Gla (and Am extracts) can yield (super 14) C values discordant with their expected age and with (super 14) C values obtained on total amino-acid fractions isolated from the same bone sample.

Bench-scale laboratory studies have demonstrated the technical feasibility of trichloroethylene (TCE) reduction to ethane by hydrogen in a Pd-catalysed hydrodehalogenation reaction under ideal conditions. This study investigated catalyst activity in bench-scale continuous-flow columns under a variety of water matrices. Deionized (DI) water caused no observable deactivation, and phosphate caused minimal deactivation when added to DI water. Nitrate, which was amended to DI water, competed with TCE for hydrogen or catalyst sites but caused no deactivation. Carbonate, carbon dioxide and groundwater from Livermore, California, all caused gradual deactivation of the palladium. Regeneration of the carbonate-deactivated catalyst through evacuation and oxidation improved catalyst activity.

The Bay Bridge is situated approximately midway between the Hayward and San Andreas faults and is aligned roughly perpendicular to the faults. Small earthquakes from both faults are recorded. Sensors for six recording sites are located at the bottom of bore-holes, and the other two recording sites are at surface rock outcrops. The Wilcoxen sensors record seismic waves from 0.05 to 200 hertz frequency and from 0.001 to 0.5 g acceleration. The recordings contain all the wave propagation characteristics of larger earthquakes from these faults, and can be analyzed to estimate the wave propagation characteristics of future large earthquakes. We develop relationships for wave passage effects, frequency dependent coherency, and individual site response. Results from this study will be compared with those applied in standard engineering practice. This information will be used to estimate bedrock strong ground motions (time-history or response spectra) at selected sites along the Bay Bridge for the Maximum Credible Earthquakes (MCEs) in the above faults as defined in the current Caltrans California Seismic Hazard Map.

Defined here, the S-ratio is the ratio of complete to incomplete chromosome translocations. It constitutes a clastogenic signature that appears to be stable over time, independent of dose, and varies inversely with the relative biological effectiveness (RBE) of the radiation. In vitro measurements resulted in a ratio of similar to 2 for densely ionizing radiation ( super(56)Fe and super(12)C ions) in contrast to a value of similar to 10 for sparsely ionizing radiation (X- and gamma -rays). The measured ratio was similar to 2 for bleomycin and benzene. Such a distinctive clastogenic signature should facilitate better estimates of neutron dose for A-bomb survivors, as well as a causal connection between early exposure to densely ionizing radiation and late development of cancer.

EIT was used to image the plume resulting from a release of 189 liters (50 gallons) of perchloroethylene (PCE) into a saturated aquifer constructed of sand and two layers of bentonite. Images were made of 4 planes, before, during and after the release, to generate a detailed picture of the spatial and the temporal development of the plume. For the first time, the electrical impedance (both in phase and out of phase voltages) was used at several different frequencies to produce images. We observed some frequency dispersion in the images before and after the PCE release. Some laboratory measurements of organic contamination in soil indicate a detectable systematic dispersion. A search for this effect in EIT images reveals weak evidence, the signal appearing just above the measurement uncertainty, of a change in the reactance (IP effect) in the soil because of the PCE.

Enewatak was one of the sites in the Pacific used to test nuclear devices between 1946 and 1958. No evidence was found to support previous reports that plutonium-238 was more mobile in the environment or more biologically available to organisms than plutonium-239 and plutonium-240. The isotopes appeared to partition equally between oxidized and reduced forms in seawater solution. The relative concentrations of plutonium-238, plutonium-239 and plutonium-240 in reef fish were not significantly different from those found in the water or food (or sediment) in the local environment. Over time, the isotopes had been released from the bottom sediments to solution at comparable rates, and had accumulated, without preferential enrichment, in abiotic and biotic constituents in the lagoon.

The site was contaminated about 50 years ago by some 8 volatile organic compounds, predominantly trichloroethylene and perchloroethylene. The alluvial materials were divided into 8 recently identified hydrostratigraphic layers and natural properties such as hydraulic conductivity, porosity or mineral sorptive capacity specified separately for the alluvial materials, the uplifted fault zone and the underlying clay layer. Within each unit Gaussian random field models were used to represent hydraulic conductivity variation as parametized from well test data and geologic interpretation of spatial variability. Six different statisticized representations of the system were made of the groundwater flow, contaminant transport and remedial extraction. There was seasonable comparison between flow and transport behaviour from the simulations and the predictions of stochastic theories based on Gaussian models, but limitations in the hydraulic data reduced the applicability of Gaussian representations. There was a need for better methods for identifying the spatial distribution and structure of geologic materials and hydraulic properties in field systems. High performance computing could help resolve transport processes in highly variable media. There are 31 references.

N1 - Last updated - 2011-12-12 ER - TY - JOUR T1 - Hydrogen at high pressures and temperatures; implications for Jupiter AN - 1356356534; 2013-041537 AB - Electrical conductivities and shock temperatures were measured for shock-compressed liquid H (sub 2) and D (sub 2) . Conductivities were measured at pressures of 93-180 GPa (0.93-1.8 Mbar). Calculated densities and temperatures were in the range 0.28-0.36 mol/cm (super 3) and 2000-4000 K. The resistivity data are interpreted in terms of a continuous transition from a semiconducting to metallic, primarily diatomic fluid at 140 GPa and 3000 K. Shock temperatures up to 5200 K were measured at pressures up to 83 GPa. These data are interpreted in terms of a continuous dissociative phase transition above 20 GPa. The continuous transition from a molecular to monatomic fluid means that Jupiter has no distinct core-mantle boundary. The dissociation model derived from the temperature measurements indicates a dissociation fraction of about 5% at 140 GPa and 3000 K. The isentrope of hydrogen was calculated starting from the surface temperature of Jupiter (165 K). At a metallization pressure of 140 GPa in Jupiter, the temperature is about 4000 K and about 10% of the hydrogen molecules are dissociated. The electrical conductivity was calculated along this isentrope by deriving a scaling relationship from the measured conductivities. The results indicate that hydrogen becomes metallic much closer to the surface of Jupiter than thought previously, a possible explanation of the very large magnetic field of Jupiter, but the metallic conductivity of the molecular fluid is two orders of magnitude lower than predicted for the monatomic fluid.

AN - 79551397; 9463520 AB - The mutagenicity of many 2-aminoimidazole-azaarenes (AIA) is thought to be mediated by the nitrenium form of the exocyclic amine. This hypothesis is supported by the numerous correlations found between calculated and experimentally-measured chemical properties for the nitreniums and the mutagenic potencies of the nitreniums and their parent amines. One factor favoring high mutagenic potency is the presence of a methyl substituent in the 1- or 3-imidazole position. In this paper, we investigate both the deprotonation of the imidazole ring nitrogens in non-N-methylated AIA mutagens and the plausibility of a chemical pathway involving a 1-4 hydride shift to form an iminium ion, thereby stabilizing the cationic N-methyl substituted AIA mutagens. It has been widely noted that factors that stabilize the nitrenium moiety lead to significantly higher mutagenic potency; hence, the transformation of the nitrenium to a more stable species might be expected to increase the potency, provided that it does not eliminate the electrophilic reactivity of the compound. Using ab initio quantum chemistry and polarizable continuum solvation models, we find that the imidazole ring nitrogens of the nitrenium ions are extremely acidic. This suggests that upon formation of the exocyclic nitrenium these sites will deprotonate to form a neutral imine. We have also studied the 1-4 hydride shift from an imidazole ring methyl to the exocyclic nitrenium to form an iminium. We predict that for AIA mutagens with just two fused rings the resulting iminium species are more stable in the gas phase than the corresponding nitreniums. For mutagens with larger conjugated systems, the nitrenium is stabilized by resonance and is more stable than the corresponding iminium. In the aqueous phase, however, the iminium form is predicted to be more stable than the nitreniums for all polycyclic compounds studied. Although equilibrium calculations favor the iminium form, these have been experimentally shown to be short-lived and their actual concentration will depend on the complex kinetics of AIA mutagen metabolism. The quantum chemical results also show a strong correlation between the relative iminium-nitrenium energy difference and the charge on the exocyclic nitrogen.

The results are then analysed to obtain first-order leaching constants for their removal from the soil units. The results give fairly reliable estimates of the concentrations of U, Th and major cations in the source dusts and in the dust of deposition. The average U contents (carbonate-free basis) of loess and palaeosols are 2.83 + or - 0.27 and 13.0 + or - 0.7 respectively, and average Th contents of the same are 2.52 + or - 0.21 and 13.3 + or - 1.2, respectively. The fraction of (super 238) U leached from parent dust in the source regions is 16% and from palaeosols 17%. Weathering in the source regions occurred within the past 10 (super 5) yr, and the weathered soils are subsequently mixed with unweathered dust in those regions during drier periods.

In this article, an algorithm is presented that locates these arrivals in single-station three-component short-period seismograms using polarization and amplitude information contained in the wavelet transform coefficients of the signals. The main idea is that strong features of the seismic signal appear in the wavelet coefficients across several scales. The first step in the algorithm is the wavelet decomposition of each component of a three-component short-period seismogram. The resulting multi-scalar representation is used to construct "locator" functions that identify the P and S arrivals. The P locator function is constructed by using polarization information across scales, and the S locator function is constructed using transverse over radial amplitude information across scales. These functions prove to be very effective at identifying the important P and S arrivals in the test data. The results are compared with arrival times picked by an analyst.

Amplitude measurements are made on both raw velocity-proportional broadband seismograms and instrument-deconvolved displacement seismograms in the time and frequency domains. Pn/Lg and Pg/Lg ratios are measured on vertical-component waveforms for regional earthquakes observed at the Global Seismic Network (GSN) station ABKT (Alibek, Turkmenistan). Time-domain amplitude measurements are made on narrow-band filtered wave-forms using signal energy measures given by the absolute mean, rms, and envelope mean, and peak measures given by the absolute maximum and envelope maximum. Frequency-domain measurements are made by computing the log (sub 10) -mean amplitude within a narrow band from the broadband spectrum of each windowed phase. Time-domain amplitude ratios for raw velocity and instrument-deconvolved displacement seismograms are very similar (linear correlations > or =0.97), indicating that the instrument response does not affect the time-domain amplitude ratio measurements for the broadband GSN data at the frequencies studied (0.75 to 9.0 Hz). Time-domain amplitude ratios made using the energy or peak measures are well correlated among themselves (linear correlations > or =0.97). However, the energy and peak measures are slightly less well correlated with each other (linear correlations between 0.87 and 0.99). For the time-domain measures, the correlations generally degrade, and the scatter increases for the higher-frequency bands. Time- and frequency-domain measurements are well correlated for the lowest-frequency band (0.75 to 1.5 Hz). However, as the frequency band increases, the correlations decrease and the slopes deviate from 1.0. Time-domain amplitude ratios (for both Pn/Lg and Pg/Lg) are consistently larger than the frequency-domain amplitude ratios. Investigation of the frequency spectra of broadband and narrow-band filtered phases revealed that significant energy from outside the passband, particularly from lower frequencies, possibly biases the time-domain measurements. Log averaging the spectral amplitudes in a given passband before forming the amplitude ratios does not bias the measurements to the low end of passband. Better agreement between time- and frequency-domain measurements is found when linear averaging of the spectrum is used. These observations suggest that with care, time- and frequency-domain measures can be made to agree. We suggest that log-averaged frequency measures look promising for discriminant measures because (1) frequency-domain measurements offer complete control of the frequencies that contribute to the measurement, and (2) log averaging of the spectra does not overweigh spectral amplitudes associated with lower frequencies within the passband. However, because we consider only earthquake data, we cannot evaluate the discrimination performance of the various measurement techniques.

Temporal and spatial distributions of simulated precipitation agreed closely with available observations. It is found that precipitation in California is closely correlated with the moisture influx from the Pacific Ocean. The observed and simulated precipitation indicates that over 70% of the total precipitation in the area during this period was associated with less than 30% of the total winter storms passing this region. Amounts of the simulated season total precipitation generally increased with elevation, with maximum precipitation, mostly in the form of snow, occurring along the ridge of the Sierra Nevada. Simulated surface snow budget indicates that snow plays a major role in seasonal surface hydrology at high elevations where most of surface runoff originates during spring and summer seasons.

To be useful, a biomarker for exposure and risk assessment should employ an end point that is highly quantitative, stable over time, and relevant to human risk. Recent advances in chromosome staining using fluorescence in situ hybridization facilitate fast and reliable measurement of simple translocations, a type of DNA damage linked both to prior clastogenic exposure and to risk. In contrast to other biomarkers available, the frequency of simple translocations in individuals exposed to whole-body radiation is stable over time postexposure, has little interindividual variability, and can be measured accurately at low frequencies.

AN - 79373809; 9355854 AB - To be most useful, a biomarker for dose reconstruction should employ an end point that is highly quantitative, stable with time and easily measured. Reciprocal translocations have been shown to be a promising biomarker that is linked to both prior exposure and risk, and they can be measured easily and quantitatively using fluorescence in situ hybridization. In contrast to other biomarkers that are available, the frequency of reciprocal translocations in individuals exposed to whole-body radiation is stable with time after exposure, has rather small interindividual variability and can be measured accurately at low levels of exposure. Results from recent studies demonstrate that measurements of reciprocal translocation frequencies, facilitated by chromosome painting, can be used to reconstruct radiation dose for individuals exposed in the distant past.

AN - 79373408; 9355858 AB - Issues central to the reliability of cytogenetic biodosimetry are presented. Although it now appears that cytogenetic biodosimetry can be used reliably to reconstruct radiation dose after acute, uniform whole-body exposure (albeit within certain dose ranges), additional data are required to fully validate cytogenetic biodosimetry for the protracted and complex exposure conditions in space. Approaches are presented that could be used to obtain the data necessary for validation. It also appears that the use of dicentric aberrations for biodosimetry on missions lasting several months or more may not be reliable because of the large variability observed among individuals in the rate of loss of cells with dicentrics, making back-extrapolations uncertain. This may be testable, however, by comparing the results for dicentrics and translocations obtained by biodosimetry with the radiation dosimetry obtained on board the spacecraft.

While surface exposure dating using cosmogenic (super 10) Be and (super 26) Al would seem to be an ideal dating method, the surfaces are composed of individual clasts, each with its own complex history of exposure and burial. The stochastic nature of burial depth and hence in nuclide production in these clasts during exhumation and fluvial transport, and during post-depositional stirring, results in great variability in clast nuclide concentrations. We present a method for dealing with the problem of pre-depositional inheritance of cosmogenic nuclides. We generate samples by amalgamating many individual clasts in order to average over their widely different exposure histories. Depth profiles of such amalgamated samples allow us to constrain the mean inheritance, to test for the possible importance of stirring, and to estimate the age of the surface. Working with samples from terraces of the Fremont River, we demonstrate that samples amalgamated from 30 clasts represent well the mean concentration. Depth profiles show the expected shifted exponential concentration profile that we attribute to the sum of uniform mean inheritance and depth-dependent post-depositional nuclide production. That the depth-dependent parts of the profiles are exponential argues against significant post-depositional displacement of clasts within the deposit. Our technique yields (super 10) Be age estimates of 60+ or -9, 102+ or -16 and 151+ or -24 ka for the three highest terraces, corresponding to isotope stages 4, 5d and 6, respectively. The mean inheritance is similar from terrace to terrace and would correspond to an error of approximately 30-40 ka if not taken into account. The inheritance likely reflects primarily the mean exhumation rates in the headwaters, of order 30 m/Ma.

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.

Previous studies of the hydraulic transmissivity function with depth indicate that an exponential function alone may not be appropriate. Recent work suggests that a first-order hyperbolic function can provide improved simulations of base flow recession in the context of TOPMODEL. We present a generalized power function for a range of possible cases and apply this function to the TOPMODEL concepts. The specific function that is most applicable is location dependent.

The resolution is between 20 and 50 years in the Holocene. During the Pleistocene, sampling was coarser, with the resolution ranging between 50 and 200 years. Both concentrations and fluxes are reported. Concentrations of (super 10) Be are observed to correlate strongly with delta (super 18) O and more weakly with snow accumulation rates. Beryllium 10 fluxes show less dependence than do concentrations on climate-related parameters. A good correlation exists between Delta (super 14) C and (super 10) Be for centennial scale variations, which are most likely due to heliomagnetic modulation of the (super 10) Be production rate in the atmosphere. There is no evidence of a long-term geomagnetic effect on the (super 10) Be flux at GISP2. The interpretation of the record depends strongly on the model one uses to infer atmospheric (super 10) Be concentrations from the measured concentrations in snow.

AN - 79420590; 9372848 AB - The cDNA sequence of the Chinese hamster ERCC2 nucleotide excision repair and transcription gene from the UVL-1 Chinese hamster ovary (CHO) mutant cell line and the V-H1 Chinese hamster V79 mutant line was analyzed. ERCC2 encodes a presumed ATP-dependent DNA helicase and is single copy in CHO lines due to the structural hemizygosity of chromosome 9. Both UVL-1 and V-H1 have intermediate levels of (6-4) photoproduct repair but are as highly UV sensitive as the group 2 mutants that have no detectable repair. Deficiency in cyclobutane dimer removal has also been shown for V-H1. In UVL-1, a single base substitution resulting in an Arg75-->Trp substitution in helicase domain Ia was identified. The equivalent amino acid position is also Arg in the human, mouse, Xiphophorus maculatus, Saccharomyces cerevisiae, and Schizosaccharomyces pombe homologs. In V-H1, a single base substitution resulting in a Thr46-->Ile substitution in helicase domain I (the ATP-binding domain) was identified in both alleles. The equivalent amino acid position is also Thr in the five homologs. Analysis of three V-H1 partial revertants revealed that they still have the original V-H1 mutation in both alleles, indicating that these are second site reversion events. Site-specific mutagenesis was used to introduce the Thr46-->Ile, Arg75-->Trp, and Lys48-->Arg (helicase domain I) mutations into a hamster ERCC2 expression plasmid. These plasmids each failed to confer UV resistance to group 2 mutant cells, further demonstrating that the changes identified are the causative mutations in V-H1 and UVL-1. Correlations between specific mutations, biochemical activities, and repair phenotype are discussed.

AN - 79208767; 9258392 AB - During 1972 to 1977, the Lawrence Livermore National Laboratory (LLNL) experienced increased diagnosis of malignant melanoma among employees. In 1984, a report on the results of a case-control study of 39 cases concluded that occupational factors, including exposures to ionizing radiation and to chemicals, caused the excess incidence. The study reported here, based on results from 69 case-control pairs, re-examines the role of the occupational factors implicated by the earlier study in melanoma causation. Results from this study suggest that constitutional factors, including skin reactivity to sunlight, sunbathing frequency, and number of moles, explain most of the excess melanoma. Exposures to occupational factors, including ionizing radiation and chemicals, were found to be no different in cases than in controls.

Once the subject of hushed conversations in the hallways and laboratories of the nation's research universities, fears of a "black hole in science employment" are featured headlines in newspapers, magazines, and broadcast media. While a genuine love of science remains the foundation of a healthy research career, nagging doubts about the availability of good jobs, job security, and compensation can cause even the most dedicated student to question the viability of a research career.

However, calculations of the flow properties of joints, whether simulated by continuous fields or discretely as a network of resistors, show that flow is maintained at appreciably larger contact areas. This behavior has been termed "channeling" in the literature. We have modified the standard effective media theory by introducing a rudimentary sort of nonrandomness in an attempt to simulate features like topographic hills and valleys. Using this new model, we calculate overestimates and underestimates of electrical and hydraulic conductivity as a function of the separation between the fracture surfaces. The underestimate is found to be very close to the standard effective media theory, real-space renormalization, and first-order perturbation theory results. The mean of the overestimate and underestimate is a good approximation to the published values found from calculations of electrical and hydraulic conductivities for simulations of real joints.

Because the model utilizes an analytical solution the transport equation, it is less computationally intensive than models based on numerical transport schemes, is faster, and it is not subject to numerical dispersion effects. Although the assumptions used to construct the model preclude consideration of reactions between the aqueous and solid phases, thermodynamic mineral saturation indices are calculated to provide qualitative insight into such reactions. Test problems involving acid mine drainage and hydrocarbon biodegradation signatures illustrate the utility of the model in simulating essential hydrogeochemical phenomena.

AN - 79414322; 9366897 AB - Trichloroethylene (TCE) is a widely used industrial chemical and a low level contaminant of surface and ground water in industrialized areas. It is weakly mutagenic in several test systems and carcinogenic in rodents. However, the mechanism for its carcinogenicity is not known. We investigated the binding of [1,2-14C]TCE ([14C]TCE) to liver DNA and proteins in male B6C3F1 mice at doses more relevant to humans than used previously. The time course for the binding was studied in animals dosed with 4.1 micrograms [14C]TCE/kg body weight (b.w.) and sacrificed between 0.5 and 120 h after i.p. injection. A dose response study was carried out in mice given [14C]TCE at doses between 2 micrograms/kg and 200 mg/kg b.w. and sacrificed 2 h post-treatment. [14C]TCE associated with the DNA and protein extracts was measured using accelerator mass spectrometry. The highest level of protein binding (2.4 ng/g protein) was observed 1 h after the treatment followed by a rapid decline, indicating pronounced instability of the adducts and/or rapid turnover of liver proteins. DNA binding was biphasic with the first peak (75 pg/g DNA) at 4 h. However, the highest binding (120 pg/g DNA) was found between 24 and 72 h after the treatment. Dose response curves were linear for both protein and DNA binding. The binding of TCE metabolites to DNA was ca. 100-fold lower than to proteins when calculated per unit weight of macromolecules and when measured 2 h post-exposure. This study shows that TCE metabolites bind to DNA and proteins in a dose-dependent manner in liver, one of the target organs for its tumorigenicity. Thus, protein and DNA adduct formation should be considered as a factor in the tumorigenesis of TCE.

AN - 79280913; 9298108 AB - The effect of ara A (9-beta-D-arabino furanosyladenine) a potent inhibitor of DNA synthesis on the frequencies of chromatid breaks induced by restriction endonucleases (RE) has been investigated in normal human and ataxia telangiectasia (AT) lymphoblastoid cells. PvuII, PstI and BamHI which cause blunt-ended, 3'-overhang and 5'-overhang cohesive-ended DNA double-strand breaks (dsb) respectively, were introduced into two AT cell lines (AT-KM and AT-PA) and a normal human (N-SW) cell line by the use of streptolysin-O poration. Controls were exposed to gamma-irradiation and similarly treated with or without ara A. Both AT cell lines were found to exhibit higher frequencies of chromatid breaks when treated with RE alone as compared with the normal cell line. The pattern of chromatid response to the three RE was shown to be similar in all three cell lines i.e. PvuII was most clastogenic while PstI and BamHI were both less effective at inducing chromosomal aberrations. Incubation of cells with ara A resulted in an increase in frequencies of chromatid breaks in PvuII and PstI treated cells but no increase was observed in BamHI treated cells. Normal cells showed most response to ara A following treatment with PvuII and PstI (enhancement ratios 4.63 and 3.75 respectively) while AT cells were affected by ara A to a lesser extent indicating a reduced expression of damage by ara A in these lines. Since ara A is a potent inhibitor of DNA synthesis, it was concluded from the elevated frequency of chromosomal aberrations in the presence of ara A that rejoining of RE-induced dsb in genomic DNA of human cells involves nucleotide insertion at dsb termini prior to ligation.

AN - 79272273; 9291352 AB - The British Nuclear Fuels plc facility at Sellafield performs a range of nuclear-related activities. The site has been in operation since 1950 and has, in general, employed a stable work force, many of whom have accumulated relatively high occupational exposures to ionizing radiation. This paper compares the physical dosimetry with two biological end points for evaluating radiation exposure: fluorescence in situ hybridization with whole-chromosome painting probes to quantify stable chromosome aberrations (translocations and insertions), and glycophorin A (GPA) analysis of variant erythrocytes. For the cytogenetic analyses, 81 workers were evaluated in five dose categories, including 23 with minimal radiation exposure (< or = 50 mSv) and 58 with exposures ranging from 173 to 1108 mSv, all but 3 being > 500 mSv. In a univariate analysis, the mean stable chromosome aberration frequencies showed a significant increase with dose category (P = 0.032), and with cumulative dose when dose is treated as a continuous variable (P = 0.015). The slope of the dose response for stable aberrations is 0.79 +/- 0.22 aberrations per 100 cells per sievert (adjusted for smoking status), which is less than that observed among atomic bomb survivors, and suggests a dose and dose-rate effectiveness factor for chronic exposure of about 6. Analyses of the data for GPA N/O and N/N variants from 36 workers revealed no correlation with dose. Neither was there a correlation between the frequencies of N/O GPA variants and stable aberrations, although a weak negative association was observed between N/N variant frequency and stable aberrations (r = -0.38, P = 0.05). These results provide clear evidence for the accumulation of stable aberrations under conditions of chronic occupational exposure to ionizing radiation and show that stable chromosome aberrations are a more sensitive indicator for chronic radiation exposure than GPA variants. In comparison with human studies of brief exposure, chronic low-dose exposures appear substantially less effective for producing somatic effects as reflected by stable chromosome aberrations.

In crude oils the major fate of alkenes is to be saturated by a labile source of hydrogen, which source probably caps hydrocarbon radicals reducing the decomposition rate of n-C (sub 16) in a crude oil matrix at approximately 350 degrees C. For T 350 degrees C the activation energy of n-C (sub 16) in crude oils is lower than that of neat C (sub 16) causing the crude oil matrix to change for stabilizing to destabilizing.

At Lawrence Livermore National Laboratory (LLNL), a methodology termed hydrostratigraphic analysis is employed to divide the heterogeneous alluvial sediments beneath LLNL into hydrostratigraphic units (HSUs). HSUs are defined as sedimentary sequences whose permeable layers show evidence of hydraulic communication and interconnection. In contrast, hydraulic communication between HSUs is restricted across HSU boundaries. HSUs are based on a comprehensive analysis and integration of chemical, geological, geophysical, and aquifer test data. The seven HSUs identified at LLNL form operational units relevant to the ground water cleanup. Within each HSU, boreholes and wells are positioned to define the relationship between source areas and individual ground water contaminant plumes. The locations of extraction wells have been optimized to hydraulically contain and isolate individual source areas and to methodically clean up the individual ground water contaminant plumes derived from these source areas. Borehole and well locations are based on detailed mapping of higher-permeability sediment distribution, ground water gradients, and contaminant distributions in soil and ground water in each HSU. Improved understanding of the subsurface features controlling contaminant flow and transport is enabling LLNL to more effectively implement remediation plans, decrease cleanup times, and reduce overall project costs. During the last 8 years, significant progress has been made towards hydraulically containing and cleaning up the contaminant plumes along the western margin of LLNL. This progress is clearly evidenced by isoconcentration time series maps, hydraulic capture maps, and mass removal rate plots for each HSU. Through these maps, hydrostratigraphic analysis has become a key tool for demonstrating cost-effective ground water cleanup to DOE, the regulators, and the community.

AN - 79207873; 9256465 AB - The Chinese hamster ovary (CHO) mutant UV40 cell line is hypersensitive to UV and ionizing radiation, simple alkylating agents, and DNA cross-linking agents. The mutant cells also have a high level of spontaneous chromosomal aberrations and 3-fold elevated sister chromatid exchange. We cloned and sequenced a human cDNA, designated XRCC9, that partially corrected the hypersensitivity of UV40 to mitomycin C, cisplatin, ethyl methanesulfonate, UV, and gamma-radiation. The spontaneous chromosomal aberrations in XRCC9 cDNA transformants were almost fully corrected whereas sister chromatid exchanges were unchanged. The XRCC9 genomic sequence was cloned and mapped to chromosome 9p13. The translated XRCC9 sequence of 622 amino acids has no similarity with known proteins. The 2.5-kb XRCC9 mRNA seen in the parental cells was undetectable in UV40 cells. The mRNA levels in testis were up to 10-fold higher compared with other human tissues and up to 100-fold higher compared with other baboon tissues. XRCC9 is a candidate tumor suppressor gene that might operate in a postreplication repair or a cell cycle checkpoint function.

The maximum mean bare-bedrock erosion rate from these alpine environments is 7.6+ or -3.9 m My (super -1) . Individual measurements vary between 2 and 19 m My (super -1) . These erosion rates are similar to previous cosmogenic radionuclide (CRN) erosion rates measured in other environments, except for those from extremely arid regions. This indicates that bare bedrock is not weathered into transportable material more rapidly in alpine environments than in other environments, even though frost weathering should be intense in these areas. Our CRN-deduced point measurements of bedrock erosion are slower than typical basin-averaged denudation rates ( approximately 50 m My (super -1) ). If our measured CRN erosion rates are accurate indicators of the rate at which summit flats are lowered by erosion, then relief in the mountain ranges examined here is probably increasing. We develop a model of outcrop erosion to investigate the magnitude of errors associated with applying the steady-state erosion model to episodically eroding outcrops. Our simulations show that interpreting measurements with the steady-state erosion model can yield erosion rates which are either greater or less than the actual long-term mean erosion rate. While errors resulting from episodic erosion are potentially greater than both measurement and production rate errors for single samples, the mean value of many steady-state erosion rate measurements provides a much better estimate of the long-term erosion rate.

Being an "open system", both in the chemical and nuclear sense, soils have defied quantitative nuclear dating. However, based on the published studies of the cosmogenic atmospheric (super 10) Be in soils, its relatively long half-life (1.5 Ma), and the fact that (super 10) Be gets quickly incorporated in most soil minerals, this radionuclide appears to be potentially the most useful for soil dating. We therefore studied the natural variations in the specific activities of (super 10) Be with respect to the isotope (super 9) Be in mineral phases in eight profiles of diverse soils from temperate to tropical climatic regimes and evaluated the implications of the data for determining the time of formation of soil minerals, following an earlier suggestion [Lal et al., 1991. Development of cosmogenic nuclear methods for the study of soil erosion and formation rates. Current Sci. 61, 636-639.]. We find that the (super 10) Be/ (super 9) Be ratios in both bulk soils and in the authigenic mineral phases are confined within a narrower range than in (super 10) Be concentrations. Also, the highest (super 10) Be/ (super 9) Be ratios in authigenic minerals are observed at the soil-rock interface as predicted by the model. We present model (super 10) Be/ (super 9) Be ages of the B-horizon and the corresponding soil formation rates for several soil profiles. The present study demonstrates that the (super 10) Be/ (super 9) Be ratios in the authigenic phases, e.g. clay and Fe-hydroxides, can indeed be used for obtaining useful model ages for soils younger than 10-15 Ma. However, the present work has to be pushed considerably further, to take into account more realistic age models in which, for instance, downward transport of (super 10) Be and clays, and in-situ dissolution of clay minerals at depths, altering the (super 10) Be/ (super 9) Be ratios of the acidic solutions, are included. We show that in the case of younger soils (<1 Ma) studied here, their (super 10) Be inventories and (super 10) Be/ (super 9) Be ratios have been significantly disturbed possibly by mixing with transported soils.

The objectives of APAC were to assess methodologies available in the accident phenomenology and consequence analysis area and to evaluate their adequacy for use in preparing DOE facility safety basis documentation, such as Basis for Interim Operation (BIO), Justification for Continued Operation (JCO), Hazard Analysis Documents, and Safety Analysis Reports (SARs). Additional objectives of APAC were to identify development needs and to define standard practices to be followed in the analyses supporting facility safety basis documentation. The Spills Working Group focused on methodologies for estimating four types of spill source terms: liquid chemical spills and evaporation, pressurized liquid/gas releases, solid spills and resuspension/sublimation, and resuspension of particulate matter from liquid spills.

AN - 50332529; 1997-067723 AB - It is widely believed that the Tibetan plateau is a late Cenozoic feature produced by the Indo-Asian collision. However, because Tibet was the locus of continental accretion and subduction throughout the Mesozoic, crustal thickening during that time may also have contributed to growth of the plateau. This portion of the geologic history was investigated in a traverse through the central Lhasa block, southern Tibet. Together with earlier studies, our mapping and geochronological results show that the Lhasa block underwent little north-south shortening during the Cenozoic. Rather, our mapping shows that approximately 60% crustal shortening, perhaps due to the collision between the Lhasa and Qiangtang blocks, occurred during the Early Cretaceous. This observation implies that a significant portion of southern Tibet was raised to perhaps 3-4 km elevation prior to the Indo-Asian collision.

We report here a detailed study in the laboratory of one of those fractures, an epidote-filled fracture in amphibolite, aimed at determining if the fracture was fluid conducting at in situ stresses and, if so, what characteristics of the fracture allowed it to remain open over geologic times. We found that the presence of the fracture made the core sample 4-7 orders of magnitude more permeable than the host rock at confining pressures near 100 MPa. Fine scale measurements of the shape of the fracture aperture, made with a specially designed profilometer, suggest that water flows through a distributed network of very small (order of 1 mm) high-aspect-ratio (order of 10) channels that cover 30-70% of the fracture surface. In contrast, fresh, well-mated fractures in granite at comparable conditions and for a comparable amount of fracture closure are slightly more compliant normal to the fracture plane and more prone to concentrate flow into channels than the mineralized fracture, suggesting fundamentally different hydraulic conduction mechanisms in fresh versus mineralized fluid-conducting fractures.

AN - 79102267; 9199234 AB - The contribution of inhalation exposure to the total dose for residents of the Marshall Islands was monitored at occasions of opportunity on several islands in the Bikini and Enewetak Atolls. To determine the long-term potential for inhalation exposure, and to understand the mechanisms of redistribution and personal exposure, additional investigations were undertaken on Bikini Island under modified and controlled conditions. Experiments were conducted to provide key parameters for the assessment of inhalation exposure from plutonium-contaminated dust aerosols: characterization of the contribution of plutonium in soil-borne aerosols as compared to sea spray and organic aerosols, determination of plutonium resuspension rates as measured by the meteorological flux-gradient method during extreme conditions of a bare-soil vs. a stabilized surface, determination of the approximate individual exposures to resuspended plutonium by traffic, and studies of exposures to individuals in different occupational environments simulated by personal air sampling of workers assigned to a variety of tasks. Enhancement factors (defined as ratios of the plutonium-activity of suspended aerosols relative to the plutonium-activity of the soil) were determined to be less than 1 (typically 0.4 to 0.7) in the undisturbed, vegetated areas, but greater than 1 (as high as 3) for the case studies of disturbed bare soil, roadside travel, and for occupational duties in fields and in and around houses.

AN - 79102225; 9199225 AB - Rongelap and Utirik Atolls were contaminated on 1 March 1954, by a U.S. nuclear test at Bikini Atoll code named BRAVO. The people at both atolls were removed from their atolls in the first few days after the detonation and were returned to their atolls at different times. Detailed studies have been carried out over the years by Lawrence Livermore National Laboratory (LLNL) to determine the radiological conditions at the atolls and estimate the doses to the populations. The contribution of each exposure pathway and radionuclide have been evaluated. All dose assessments show that the major potential contribution to the estimated dose is 137Cs uptake via the terrestrial food chain. Brookhaven National Laboratory (BNL) has carried out an extensive whole body counting program at both atolls over several years to directly measure the 137Cs body burden. Here we compare the estimates of the body burdens from the LLNL environmental method with body burdens measured by the BNL whole body counting method. The combination of the results from both methods is used to evaluate proposed diet models to establish more realistic dose assessments. Very good agreement is achieved between the two methods with a diet model that includes both local and imported foods. Other diet models greatly overestimate the body burdens (i.e., dose) observed by whole body counting. The upper 95% confidence limit of interindividual variability around the population mean value based on the environmental method is similar to that calculated from direct measurement by whole body counting. Moreover, the uncertainty in the population mean value based on the environmental method is in very good agreement with the whole body counting data. This provides additional confidence in extrapolating the estimated doses calculated by the environmental method to other islands and atolls.

AN - 79095616; 9199222 AB - Uncertainty and interindividual variability were assessed in estimated doses for a rehabilitation scenario for Bikini Island at Bikini Atoll, in which the top 40 cm of soil would be removed in the housing and village area, and the rest of the island would be treated with potassium fertilizer, prior to an assumed resettlement date of 1999. Doses were estimated for ingested 137Cs and 90Sr, external gamma-exposure, and inhalation+ingestion of 241Am + 239+240Pu. Two dietary scenarios were considered: imported foods are available (IA); imported foods are unavailable with only local foods consumed (IUA). After approximately 5 y of Bikini residence under either IA or IUA assumptions, upper and lower 95% confidence limits on interindividual variability in calculated dose were estimated to lie within a approximately threefold factor of its in population-average value; upper and lower 95% confidence limits on uncertainty in calculated dose were estimated to lie within a approximately twofold factor of its expected value. For reference, the expected values of population-average dose at age 70 y were estimated to be 16 and 52 mSv under IA and IUA dietary assumptions, respectively. Assuming that 200 Bikini resettlers would be exposed to local foods (under both IA and IUA assumptions), the maximum 1-y dose received by any Bikini resident is most likely to be approximately 2 and 8 mSv under the IA and IUA assumptions, respectively. Under the most likely dietary scenario, involving access to imported foods, this analysis indicates that it is most likely that no additional cancer fatalities (above those normally expected) would arise from the increased radiation exposures considered.

AN - 79095575; 9199221 AB - On 1 March 1954, a nuclear weapon test, code-named BRAVO, conducted at Bikini Atoll in the northern Marshall Islands contaminated the major residence island. There has been a continuing effort since 1977 to refine dose assessments for resettlement options at Bikini Atoll. Here we provide a radiological dose assessment for the main residence island, Bikini, using extensive radionuclide concentration data derived from analysis of food crops, ground water, cistern water, fish and other marine species, animals, air, and soil collected at Bikini Island as part of our continuing research and monitoring program that began in 1978. The unique composition of coral soil greatly alters the relative contribution of 137Cs and 90Sr to the total estimated dose relative to expectations based on North American and European soils. Without counter measures, 137Cs produces 96% of the estimated dose for returning residents, mostly through uptake from the soil to terrestrial food crops but also from external gamma exposure. The doses are calculated assuming a resettlement date of 1999. The estimated maximum annual effective dose for current island conditions is 4.0 mSv when imported foods, which are now an established part of the diet, are available. The 30-, 50-, and 70-y integral effective doses are 91 mSv, 130 mSv, and 150 mSv, respectively. A detailed uncertainty analysis for these dose estimates is presented in a companion paper in this issue. We have evaluated various countermeasures to reduce 137Cs in food crops. Treatment with potassium reduces the uptake of 137Cs into food crops, and therefore the ingestion dose, to about 5% of pretreatment levels and has essentially no negative environmental consequences. We have calculated the dose for the rehabilitation scenario where the top 40 cm of soil is removed in the housing and village area, and the rest of the island is treated with potassium fertilizer; the maximum annual effective dose is 0.41 mSv and the 30-, 50-, and 70-y integral effective doses are 9.8 mSv, 14 mSv, and 16 mSv, respectively.

A radiological survey at some Northern Marshall Islands was conducted from September through November 1978 to evaluate the extent of residual radioactive contamination. The atolls included in the Northern Marshall Islands Radiological Survey (NMIRS) were Likiep, Ailuk, Utirik, Wotho, Ujelang, Taka, Rongelap, Rongerik, Bikar, Ailinginae, and Mejit and Jemo Islands. The original test sites, Bikini and Enewetak Atolls, were also visited on the survey. An aerial survey was conducted to determine the external gamma exposure rate. Terrestrial (soil, food crops, animals, and native vegetation), cistern and well water samples, and marine (sediment, seawater, fish and clams) samples were collected to evaluate radionuclide concentrations in the atoll environment. Samples were processed and analyzed for 137Cs, 90Sr, 239+240Pu and 241Am. The dose from the ingestion pathway was calculated using the radionuclide concentration data and a diet model for local food, marine, and water consumption. The ingestion pathway contributes 70% to 90% of the estimated dose. Approximately 95% of the dose is from 137Cs. 90Sr is the second most significant radionuclide via ingestion. External gamma exposure from 137Cs accounts for about 10% to 30% of the dose. 239+240Pu and 241Am are the major contributors to dose via the inhalation pathway; however, inhalation accounts for only about 1% of the total estimated dose, based on surface soil levels and resuspension studies. All doses are computed for concentrations decay corrected to 1996. The maximum annual effective dose from manmade radionuclides at these atolls ranges from .02 mSv y(-1) to 2.1 mSv y(-1). The background dose in the Marshall Islands is estimated to be 2.4 mSv y(-1). The combined dose from both background and bomb related radionuclides ranges from slightly over 2.4 mSv y(-1) to 4.5 mSv y(-1). The 50-y integral dose ranges from 0.5 to 65 mSv.

AN - 79079330; 9199218 AB - Bikini and Enewetak were the sites in the Northern Marshall Islands that were used by the United States as testing grounds for nuclear devices between 1946 and 1958. The testing produced close-in fallout debris that was contaminated with different radionuclides and which entered the aquatic environment. The contaminated lagoon sediments became a reservoir and source term of manmade radionuclides for the resident marine organisms. This report contains a summary of all the available data on the concentrations of 137Cs, 60Co and 207Bi in flesh samples of reef and pelagic fish collected from Bikini and Enewetak Atolls between 1964 and 1995. The selection of these three radionuclides for discussion is based on the fact that these are the only radionuclides that have been routinely detected by gamma spectrometry in flesh samples from all fish for the last 20 y. Flesh from fish is an important source of food in the Marshallese diet. These radionuclides along with the transuranic radionuclides and 90Sr contribute most of the small radiological dose from ingesting marine foods. Some basic relationships among concentrations in different tissues and organs are discussed. The reef fish can be used as indicator species because their body burden is derived from feeding, over a lifetime, within a relatively small contaminated area of the lagoon. Therefore, the emphasis of this report is to use this extensive and unique concentration data base to describe the effective half lives and cycling for the radionuclides in the marine environments during the 31-y period between 1964 and 1995. The results from an analysis of the radionuclide concentrations in the flesh samples indicate the removal rates for the 3 radionuclides are significantly different. 137Cs is removed from the lagoons with an effective half life of 9-12 y. Little 60Co is mobilized to the water column so that it is depleted in both environments, primarily through radioactive decay. The properties of 207Bi are different at Enewetak and Bikini. At Enewetak the radionuclide is lost from the environment with an effective half live of 5.1 y. At Bikini only radioactive decay can account for the rate at which the radionuclide is lost from the lagoon. The difference in the binding properties of the sedimentary materials for 207Bi among the two Atolls is not understood.

Calibration is required to confidently use these stations to identify and discriminate between earthquakes, mine-related events and clandestine nuclear explosions, particularly for small to moderate seismic events recorded regionally at only a few stations. Given the lack of regional recordings of underground nuclear tests in most of the world, we are making use of mining and industrial explosions to test discriminants. For example we use the Multimax compiled dataset of small earthquakes and quarry explosions in Israel to test regional discriminants at local distances with mixed results. Further complicating calibration is the fact that many INK sites have not yet been installed and others have very short operating histories. When IMS data is available, there is often a lack of independent information (ground truth) on the seismic sources. Here we describe a procedure for calibrating stations with limited data and apply it to the IMS auxiliary station MDT in Morocco. Data was initially available for three months in 1990 when MDT was operated as part of MEDNET. An event detector was run over the continuous data and regional events identified and roughly located using S-P time and back azimuth. The procedure uses spatial and temporal clustering to identify "known" mine blasts. The spatial clustering is done using the waveform correlation technique of Harris (1991) to find events with similar sources and locations. Temporal clustering looks at the time of day and repetition in time of events with the mine blasts occurring during working hours and days repeatedly over a period of time. A set of "known" earthquakes is also determined using location, time of day, distribution in time and size criteria. With these independent libraries of identified seismic events, we evaluate promising regional discriminants such as high frequency P/Lg. We also examine distance and path effects on the discriminants. Preliminary results indicate high frequency P/Lg provides some separation between mine blasts and earthquakes at MDT.

The (super 36) Cl/Cl values for several geothermal water samples and reservoir host rock samples from the Coso, California geothermal field have been measured for these purposes. The results indicate that most of the chlorine is not derived from the dominant granitoid that host the geothermal system. If the chlorine was originally input into the Coso subsurface through meteoric recharge, that input occurred at least 1-1.25 million years ago. The results suggest that the thermal waters could be connate waters derived from sedimentary formations, presumably underlying and adjacent top the granitic rocks, which have recently migrated into the host rocks. Alternatively, most of the chlorine but not the water, may have recently input into the system from magmatic sources. In either case, the results indicate that most of the chlorine in the thermal waters has existed within the granitoid host rocks for no more than about 100,00-200,00 years. this residence time for the chlorine is similar to residence times suggested by other researchers for chlorine in deep groundwaters of the Mono Basin north of the Coso field.

Unfortunately, most existing techniques are empirical and can not be used reliably in new regions. Our goal is to help develop transportable regional identification techniques by improving our ability to predict the behavior of regional phases and discriminants in diverse geologic regions and in regions with little or no data. Our approach is to use numerical modeling to understand the physical basis for regional wave propagation phenomena and to use this understanding to help explain observed behavior of regional phases and discriminants. In this paper, we focus on results from simulations of data in selected regions and investigate the sensitivity of these regional simulations to various features of the crustal structure. Our initial models use teleseismically estimated source locations, mechanisms, and durations and seismological structures that have been determined by others. We model the Mb 5.9, October 1992, Cairo Egypt earthquake at a station at Ankara Turkey (ANTO) using a two-dimensional crustal model consisting of a water layer over a deep sedimentary basin with a thinning crust beneath the basin. Despite the complex tectonics of the Eastern Mediterranean region, we find surprisingly good agreement between the observed data and synthetics based on this relatively smooth two-dimensional model.

This process can be used as an electrical y-regenerated alternative to ion exchange, thereby reducing-the need for large quantities of chemical regenerants. Once spent (contaminated), these regenerants contribute to the waste that must be disposed of in landfills. The elimination of such wastes is especially beneficial in situations involving radioactive contaminants, and pump and treat processing of massive volumes of ground water.

Here, a general multi-species reactive transport formulation has been developed, which is applicable to homogeneous and/or heterogeneous reactions that can proceed either subject to local equilibrium conditions or kinetic rates under non-isothermal multiphase flow conditions. Two numerical solution methods, the direct substitution approach (DSA) and sequential iteration approach (SIA) for solving the coupled complex subsurface thermo-physical-chemical processes, are described. An efficient sequential iteration approach, which solves transport of solutes and chemical reactions sequentially and iteratively, is proposed for the current reactive chemical transport computer code development. The coupled flow (water, vapor, air and heat) and solute transport equations are also solved sequentially.

Conflicting data have occasionally come from different laboratories, and refinement of experimental techniques has led to the publication of laws that supersede earlier ones. In addition, there are unpublished data from ongoing research that also amend the constitutive laws. Here we compile the most current laboratory-derived flow laws for water ice phases I, II, III, V, and VI, and ice I mixtures with hard particulates. The rheology of interest is mainly that of steady state, and the conditions reviewed are the pressures and temperatures applicable to the surfaces and interiors of icy moons of the outer solar system. Advances in grain-size-dependent creep in ices I and II as well as in phase transformations and metastability under differential stress are also included in this compilation. At laboratory strain rates the several ice polymorphs are rheologically distinct in terms of their stress, temperature, and pressure dependencies but, with the exception of ice III, have fairly similar strengths. Hard particulates strengthen ice I significantly only at high particulate volume fractions. Ice III has the potential for significantly affecting mantle dynamics because it is much weaker than the other polymorphs and its region of stability, which may extend metastably well into what is nominally the ice II field, is located near likely geotherms of large icy moons.

Electrical conductivity sigma was measured to 250 MPa pressure, and room temperature on 1 M NaCl-saturated amphibolites from 4 to 5 km depth. An unexpected feature was an increase of sigma with pressure P that appeared (anisotropically) in most samples. To characterize this behavior, we fitted the linear portion of log sigma versus P to obtain two parameters: the slope dlogsigma /dP (of order 10 (super -3) MPa (super -1) ) and the zero-pressure intercept sigma (sub 0) . Samples of positive and negative slopes behave differently. Those having negative slopes show strong correlation of sigma (sub 0) with a fluid property (permeability). This behavior indicates that fluids exert the dominant control on sigma (sub 0) at low pressure when sigma (sub 0) is greatest, which is typical behavior observed in previous studies. In contrast, samples with positive slopes lack a correlation of sigma (sub 0) with permeability, indicating that fluids are less important to positive pressure behavior. Another result is that samples of negative dlogsigma /dP have uncorrelated slopes and initial conductivities. In significant contrast, samples of positive slopes have the greatest P dependence for lowest initial conductivity sigma (sub 0) , that is, the less fluid, the more positive dlogsigma /dP. Hence positive dlogsigma /dP is consistent with reconnection of solid phases into a conductive texture better resembling that of rock at depth. Detailed examination of one sample by electron probe and scanning electron microscope reveals the presence of carbon on internal cleavage surfaces in amphibole, the most abundant mineral present. Thus carbon probably dominates the reconnection, but total sigma still involves fluids as well as Fe-Ti oxides. For the KTB location it is inferred that the reason mid to deep crustal electrical conductivities modeled from geophysical measurements are so much higher than conductivities of silicates is the presence of interconnected good conductors involving films of carbon on surfaces and other solid phases.

The people at both atolls were removed from their atolls in the first few days after the detonation and were returned to their atolls at different times. Detailed studies have been carried out over the years by Lawrence Livermore National Laboratory (LLNL) to determine the radiological conditions at the atolls and estimate the doses to the populations. The contribution of each exposure pathway and radionuclide have been evaluated. All dose assessments show that the major potential contribution to the estiamted dose is super(137)Cs uptake via the terrestrial food chain. Brookhaven National Laboratory (BNL) has carried out an extensive whole body counting program at both atolls over several years to directly measure the super(137)Cs body burden. Here we compare the estimates of the body burdens from the LLNL environmental method with body burdens measured by the BNL whole body counting method. The combination of the results from both methods is used to evaluate proposed diet models to establish more realistic dose assessments. Very good agreement is achieved between the two methods with a diet model that includes both local and imported foods. Other diet models greatly overestimate the body burdens (i.e., dose) observed by whole body counting. The upper 95% confidence limit of interindividual variability around the population mean value based on the environmental method is similar to that calculated from direct measurement by whole body counting. Moreover, the uncertainty in the population mean value based on the environmental method is in very good agreement with the whole body counting data. This provides additional confidence in extrapolating the estimated doses calculated by the environmental method to other islands and atolls.

Heavily confined cylinders of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) and triaminotrinitrobenzene (TATB) were heated at rates varying from 2 degree C/min to 3.3 degree C/h. Fourteen of the cylinders were hollow, and inner metallic liners with small heaters attached were used to produce uniform temperatures just prior to explosion. A complex thermocouple pattern was used to measure the temperature history throughout the charge and to determine the approximate location where the runaway exothermic reaction first occurred. The violence of the resulting explosion was measured using velocity pin arrays placed inside and outside of the metal confinement cylinders, flash x-rays, overpressure gauges, and fragment collection techniques. Five cylinders were intentionally detonated for violence comparisons. The measured temperature histories, times to explosion, and the locations of first reaction agreed closely with those calculated by a two-dimensional heat transfer code using multistep chemical decomposition models. The acceleration of the confining metal cylinders by the explosion process was accurately simulated using a two-dimensional pressure dependent deflagration reactive flow hydrodynamic model. The most violent HMX thermal explosions gradually accelerated their outer cases to velocities approaching those of intentional detonations approximately 120 mu s after the onset of explosion. The measured inner cylinder collapse velocities from thermal explosions were considerably lower than those produced by detonations. In contrast to the HMX thermal reactions, no violent thermal explosions were produced by the TATB-based explosive LX-17. A heavily confined, slowly heated LX-17 test produced sufficient pressure to cause a 0.1 cm bend in a 2 cm thick steel plate.

AN - 79168373; 9248041 AB - The events associated with the death of Gloria Ramirez at Riverside General Hospital on 19 February 1994 have been portrayed as a major medical mystery. A potential chemical explanation for this incident has been developed. The hypothetical scenario depends upon the oxidation of a common solvent, dimethyl sulfoxide, through dimethyl sulfone to dimethyl sulfate. The latter compound is a volatile and highly toxic agent that can be quite hazardous to humans in small amounts. It is also environmentally nonpersistent. Much of the mystery surrounding the circumstances at the hospital may be explainable if this postulated metabolic pathway took place at the time of the emergency room incident. Although dimethyl sulfate was not detected in any analyses pertinent to this event, there are plausible scientific explanations to account for that fact. The sulfate anion, a hydrolysis product of dimethyl sulfate, was measured at an appreciably elevated concentration in Ramirez' blood. The descriptions of the symptoms of the hospital-staff victims appear quite consistent with dimethyl sulfate exposures. This paper attempts to make some sense of the reported data and eyewitness accounts, and perhaps provide new insight for any future research that could further explain this reported occurrence of toxic exposure.

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.

Time series with bimonthly resolution were constructed using accelerator mass spectrometry. The seasonal variability ranges from 15 to 60 per mil, with large interannual variability. Delta (super 14) C values from Indonesia and Guam have a nearly identical range. Annual mean Delta (super 14) C values from Indonesia are 50 to 60 per mil higher than in corals from Canton in the South Equatorial Current [Druffel, 1987 ]. These observations support a year-round North Pacific source for the Indonesian throughflow and imply negligible contribution by South Equatorial Current water. The large seasonality in Delta (super 14) C values from both sites emphasizes the dynamic behavior of radiocarbon in the surface ocean and suggests that Delta (super 14) C time series of similar resolution can help constrain seasonal and interannual changes in ocean circulation in the Pacific over the last several decades.

In our "control" simulation, rejected salt goes into the top model layer, and simulated salinities are typical of OGCMs: the deep ocean is too fresh, and the intermediate-depth salinity minimum associated with Antarctic Intermediate Water is absent. These problems are eliminated in our "test" simulation, in which we distribute rejected salt uniformly over the upper 160 m. Also, the strength of the Antarctic Circumpolar Current is more realistic in this simulation. These results show the need for, but do not provide, a better representation of sinking of rejected salt. The sensitivity of our model to sinking of rejected salt suggests that a similar sensitivity may exist in the real ocean, and that loss of Antarctic sea ice might have major effects.

This bacterium can be cultivated more conveniently at 45 degree C, a temperature substantially lower than its optimal growth temperature (approx. 60 degree C). Yet, the washed harvested cells from such cultures display the same initial BTEX-degrading activity as those when Thermus sp. is grown at its higher optimal temperature. Two bioreactor cultivation modes, batch and fed batch, were investigated. More biomass and more BTEX-degrading activity (assayed at 60 degree C) were generated in fed-batch cultures than in the growth-limited batch cultures. The former yielded a biomass concentration of 2.5 g dry cell weight (DCW) l super(-1) and whole-cell degrading specific activities of 7.6 plus or minus 1.3, 10.1 plus or minus 1.9, 9.8 plus or minus 2.1, 2.3 plus or minus 0.5, and 4.6 plus or minus 0.9 nmol degraded (mg DCW) super(-1) min super(-1) for benzene, toluene, ethylbenzene, m-xylene, and the o- plus p-xylenes (unresolved mixture), respectively. Although the formation of cellular BTEX-degrading activity is growth-associated, a slow to moderate specific growth rate of 0.02 0.07 h super(-1) favors the production of BTEX-degrading activity, while a high growth rate, of the order of 0.16 h super(-1), is detrimental to its production. The washed harvested Thermus sp. cells were capable of degrading BTEX over a broad range of thermophilic incubation temperatures, 45-77 degree C.

AN - 79110032; 9216741 AB - This study compared heterocyclic aromatic amines in marinated and unmarinated chicken breast meat flame-broiled on a propane grill. Chicken was marinated prior to grilling and the levels of several heterocyclic amines formed during cooking were determined by solid-phase extraction and HPLC. Compared with unmarinated controls, a 92-99% decrease in 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) was observed in whole chicken breast marinated with a mixture of brown sugar, olive oil, cider vinegar, garlic, mustard, lemon juice and salt, then grilled for 10, 20, 30 or 40 min. Conversely, 2-amino-3, 8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) increased over 10-fold with marinating, but only at the 30 and 40 min cooking times. Marinating reduced the total detectable heterocyclic amines from 56 to 1.7 ng/g, from 158 to 10 ng/g and from 330 to 44 ng/g for grilling times of 20, 30 and 40 min, respectively. The mutagenic activity of the sample extracts was also measured, using the Ames/Salmonella assay. Mutagenic activity was lower in marinated samples cooked for 10, 20 and 30 min, but higher in the marinated samples cooked for 40 min, compared with unmarinated controls. Although a change in free amino acids, which are heterocyclic amine precursors, might explain the decrease in PhIP and increase in MeIQx, no such change was detected. Marinating chicken in one ingredient at a time showed that sugar was involved in the increased MeIQx, but the reason for the decrease in PhIP was unclear. PhIP decreased in grilled chicken after marinating with several individual ingredients. This work shows that marinating is one method that can significantly reduce PhIP concentration in grilled chicken.

AN - 78968622; 9140398 AB - Each year more than 20,000 children and young persons of reproductive age are exposed to known mutagens in the form of chemo- and/or radiotherapy for cancer in the States. As more of these treatments are effective there is growing concern that genetic defects are introduced in the germ cells of these young patients. It is well documented for male rodents that treatment with chemo- and radio-therapeutic agents before mating can cause genetic damage in the germ line, and the magnitude of heritable effects depends on the spermatogenic cell stage treated. Similar germinal effects are suspected to occur in humans but remain unproven. Hodgkin's disease (HD) is an example of a malignancy which is typically diagnosed during a patient's reproductive years. In our study we observed eight male HD patients who were treated with NOVP (Novanthrone, Oncovin, Vinblastine, Prednisone) chemotherapy. We evaluated sperm aneuploidy using multi-colour fluorescence in situ hybridization (FISH), and found approximately 5-fold increases in sperm with disomies, diploidies and complex genotypes involving chromosome X, Y and 8. Increases in sex chromosome aneuploidies arose from segregation errors at meiosis I as well as meiosis II. The aneuploidy effects were transient, however, declining to pretreatment levels within approximately 100 days after the end of the therapy. When compared with normal men, some HD patients showed higher proportions of certain sperm aneuploidy types even before their first therapy.

Improvement on the measurement of thermal expansivity is needed since at high temperatures thermal expansivity is the least accurate of the properties needed in thermodynamic studies. Thermal expansivity data is essential in the high temperature thermal dynamics study of important minerals in the Earth. The differential laser interferometry is a new method, simultaneously monitoring two fringe signals which are 90 degree out of phase. We eliminated the error caused by heat in the signal processing. The overall sensitivity in which we can detect changes in length is about 1/100 of the wave length of the He-Ne laser (1/100 of 0.6328X10 (super -6) m). We calibrated the device by measuring the thermal expansivity for single crystals of Al (sub 2) O (sub 3) and MgO up to 1000 K.

Analytical models and soil parameters for SHAKE analysis were developed from geotechnical data obtained from several site investigation programs conducted at the site in 1960, 1991 and 1995. Two sets of rock outcropping input motions were used: (1) modified Santa Cruz earthquake records provided by Caltrans, and (2) LLNL synthetic strong ground motions. The LLNL synthetic ground motions were developed using LLNL Empirical Green functions method simulating strong earthquakes of moment magnitude 7.25 from the nearby Hayward Fault about 4 km from the site. Calculated ground surface motions using LLNL median rock input-motions are compatible with Caltrans design/evaluation motions.

These same compounds produce tumors at multiple organ sites in both mice and rats. One example of these induced tumors has also been seen in nonhuman primates. Risk assessment for the human population consuming these compounds requires the integration of knowledge of dosimetry, metabolism, carcinogenic potency, and epidemiology. When this integration is done in even a preliminary way as is done here, the range of risk for an individual from these compounds is enormous. Exposure contributes a range of 200-fold or more and metabolism and DNA repair differences among individuals could easily be an additional 10-fold between individuals. This indicates that differences in human cancer risk for heterocyclic amines could range more than a thousandfold between individuals based on exposure and genetic susceptibility.

The amines require activation by enzymes to form metabolites reactive with DNA and exhibit an enormous range of potency as frameshift mutagens in the Ames/Salmonella assay. To ascertain factors that might influence potency, structural features and quantum mechanical parameters calculated by the Huckel method (and, for a subset of 20 amines, by semi-empirical AM1, and ab initio methods) were analyzed by multiple linear regression. The major findings were: (1) earlier findings on cooked food mutagens and their synthetic congeners can be extended to other amines; (2) mutagenic potency is directly related to the number of fused aromatic rings (size of the aromatic system), the number of ring nitrogen atoms (participation of lone electron pairs in the pi-cloud), and presence of a methyl substituent on a ring nitrogen; (3) potency is inversely related to the energy of the lowest unoccupied molecular orbital (LUMO) of the parent amine. [FORD AND GRIFFIN (1992)] and [SABBIONI AND WILD (1992)] showed that the LUMO energy of the derived nitrenium ion is closely related to its stability (calculated with reference to aniline). Increased stability has been hypothesized to enhance the probability of adduct formation with DNA by avoiding detoxifying side reactions and increasing the lifetime of the ion. In the large heterogeneous series of amines in our present study the Huckel method energy of the highest occupied molecular orbital (HOMO), rather than the LUMO energy, of the nitrenium ion was marginally related to the potency of the parent amine. However, in the selected subset of 20 amines with ab initio calculation, the LUMO energy of the ion confirmed the previous reports. The contribution of quantum chemical factors to mechanistic insight on the mutagenicity and carcinogenicity of aromatic and heterocyclic amines is still under development.

Human exposure to MeIQx has been estimated to range from ng/person/day to a few mu g/person/day. In contrast, animal studies have been conducted at doses in excess of 10 mg/kg /day. In order to determine the relevance of high-dose animal data for human exposure, the dose-response curves for [14C]-MeIQx have been determined in rodents at low doses under both single-dose and chronic dosing regimens using the high sensitivity of accelerator mass spectrometry (AMS). To make a direct species comparison, rodent and human colonic MeIQx-DNA adduct levels have been compared following oral administration of [14C]-MeIQx. The results of these studies show: (1) total MeIQx levels are highest in the liver {unknown entity >>}kidney>pancreas>intestine>blood; (2) MeIQx levels in the liver plateau after 7 days of chronic feeding; (3) hepatic MeIQx-DNA adducts begin to plateau after 2-4 weeks and reach steady-state levels between 4 and 12 weeks on chronic exposures; (4) hepatic DNA adducts generally increase as a linear function of administered dose for a single-dose exposure and as a power function for chronic feeding over a dose range spanning 4 orders of magnitude; (5) human colon DNA adduct levels are similar to 10 times greater than in rodents at the same dose and time point following exposure; and (6) greater than or equal to 90% of the MeIQx-DNA adduct in both rodent and human colon appears to be the dG-C8-MeIQx adduct. These studies show that MeIQx is readily available to the tissues for both humans and rodents and that adduct levels are generally linear with administered dose except at high chronic doses where adduct levels begin to plateau slightly. This plateau indicates that linear extrapolation from high-dose studies probably underestimates the amount of DNA damage present in the tissues following low dose. Further, if adducts represent the biologically effective dose, these data show that human colon may be as sensitive to the genotoxic effects of MeIQx as rat liver. The significance of these endpoints to tumor response remains to be determined.

The most commonly reported and abundant compounds are PhIP, MeIQx, DiMeIQx, IQ and A alpha C. Using analysis by solid-phase extraction and HPLC, amounts found in foods range from less than one ng/g for products from fast-food restaurants, up to 14 ng/g in commercially cooked products and over 300 ng/g for well done flame-grilled chicken breast meat. Interestingly, marinating meat for 4 h greatly reduces the amount of PhIP produced during cooking, but not MeIQx. Comparing mutagenic activity in meat samples to the mutagenic activity accounted for by the known heterocyclic amines shows that most samples have activity that cannot be accounted for by the aromatic amines we can currently identify. This suggests that additional compounds are present in these foods and need to be investigated, particularly those grilled over open flames.

Digital waveform data from the Iranian Long Period Array (ILPA) and the Global Seismic Network (GSN) stations ABKT (Alibek, Turkmenistan), ANTO (Ankara, Turkey), KEG (Kottamya, Egypt), and KIV (Kislovodsk, Georgia) were used in this study. Three-component rotated seismograms were bandpass filtered (0.5 to 5.0 Hz) and examined for the presence and strength (amplitude) of Sn and Lg relative to the Pn and Pg phases. The short-period Sn and Lg waveforms show great variability. Sn propagates efficiently for paths crossing the Mediterranean, Black, and Caspian Seas as well as for paths passing north of the Greater Caucasus, Alborz, and Kopet-Dag Mountains. Generally, Sn is not observed or propagates inefficiently for paths with segments beneath the Turkish plateau and northern Iranian plateau, consistent with a previous study by Kadinsky-Cade et al. (1981). This study finds that the zone of inefficient Sn propagation coincides with a zone of low Pn velocities (<7.9 km/sec) determined by Hearn and Ni (1994) from Pn tomography. Lg is consistently not observed for paths crossing the Mediterranean, Black, and Caspian Seas. Lg propagates efficiently for paths crossing the northern Arabian shield. Generally, Lg propagates efficiently for paths contained within the Turkish-Iranian plateau. Paths in the Middle East greater than about 2000 km consistently show no or little Lg energy. The correspondence of zones of inefficient Sn propagation and low Pn velocities suggests that high temperatures and partial melt lie at shallow depths in the upper mantle beneath the Turkish plateau and northern Iranian plateau. The presence of water, presumably due to subduction of hydrated oceanic crust, lowers the solidus temperature and enhances partial melt. Lg is blocked by oceanic crustal structures as well as by structural and topographic variations associated with tectonic boundaries.

The geochemical results indicate that the source region(s) for these rocks are more refractory than a MORB source. Distinct source-domains are identified within the Izu-Bonin and central and NE Honshu arc; it is suggested that these may be due to magma interaction with subcontinental lithosphere.

The Closure Plan (Chapter 1) and the Post-Closure Plan (Chapter 2) address the concept of long-term hazard elimination. The Closure Plan provides for capping and grading the HE Open Burn Treatment Facility and revegetating the immediate area in accordance with applicable requirements. The Closure Plan also reflects careful consideration of site location and topography, geologic and hydrologic factors, climate, cover characteristics, type and amount of wastes, and the potential for contaminant migration. The Post-Closure Plan is designed to allow LLNL to monitor the movement, if any, of pollutants from the treatment area. In addition, quarterly inspections will ensure that all surfaces of the closed facility, including the cover and diversion ditches, remain in good repair, thus precluding the potential for contaminant migration.

The results of such an analysis are expressed as estimated probabilities per year or estimated annual frequencies. The objective of this project has been to provide methodological guidance on how to perform a PSHA. The project, co-sponsored by the U.S. Nuclear Regulatory Commission, the U.S. Department of Energy, and the Electric Power Research Institute, has been carried out by a seven-member Senior Seismic Hazard Analysis Committee (SSHAC), supported by a large number of other experts working under the Committee's guidance. The scope of the SSHAC guidance is intended to cover both site-specific and regional applications of PSHA (more broadly, applications in both low-seismicity and high-seismicity regions) in both the eastern U.S. and western U.S. Although the sponsors' primary objective is guidance for applications at nuclear power plants and other critical facilities, the methodological guidance applies in whole or in part, on a case-by-case basis, to a broad range of applications.

The offshore thermal gradient, derived from foraminiferal species assemblages and oxygen isotope data, was similar at the LGM to that at present (warmer offshore), but average temperatures were 3.3 degrees + or -1.5 degrees C colder. Observed gradients require that the sites remained under the southward flow of the California Current, and thus that the polar front remained north of 42 degrees N during the LGM. Carbon isotopic and foraminiferal flux data suggests enhanced nutrients and productivity of foraminfera in the northern California Current up to 650 km offshore. In contrast, marine organic carbon and coastal diatom burial rates decreased during the LGM. These seemingly contradictory results are reconciled by model simulations of the LGM wind- field, which suggest that wind stress curl at 42 degrees N (and thus open-ocean upwelling) increased, while offshore Ekman transport (and thus coastal upwelling) decreased during the last ice age. The ecosystem of the northern California Current during the LGM approximated that of the modern Gulf of Alaska. Cooling and production in this region was thus driven by stronger open-ocean upwelling and/or southward flow of high-latitude water masses, rather than by coastal upwelling.

The Chinese hamster ovary UV5P3 cells are approximately 50-fold more sensitive to the cooked food mutagen, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) than 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), another genotoxic compound found in cooked food, with respect to cytotoxicity and mutation induction at the adenine phosphoribosyltransferase (aprt) locus. To test the hypothesis that the important missing activity in our CHO system for IQ genotoxicity was acetyltransferase, we transfected the UV5P3 cells with cDNA plasmids of either the human NAT2 N-acetyltransferase gene or a bacterial O-acetyltransferase gene. Functionally transformed clones were determined by the differential cytotoxicity assay using IQ, and confirmed by measuring the enzyme activity with isoniazid as substrate. Two clones designated 5P3NAT2 and 5P3YG (expressing human and bacterial transferases, respectively) were characterized. Both cell lines were sensitive to killing by IQ at concentrations as low as 4 ng /ml. Based on the D37 value, the dose that reduced the survival to 37% relative to untreated controls, the acetyltransferase expressing lines showed similar to 1000-fold increase in sensitivity to the killing effects of IQ over the parental UV5P3 cell line. The same dramatic change in sensitivity was also seen in mutation response at the aprt locus and with chromosomal aberrations and sister chromatid exchanges. In contrast, these cell lines showed cytotoxicity to PhIP similar to that of the parental line UV5P3. These results suggest that PhIP does not require acetyltransferase for metabolic activation leading to genotoxicity in these cells. These new cell lines constitute a sensitive cell system for assessing genotoxicity of compounds requiring metabolic activation by both P450IA2 and acetyltransferase, as well as for studying the molecular processes by which DNA damage can lead to mutation and cancer.

III. Guidelines for field studies of male reproductive disorders. AN - 78955923; 9100299 AB - Exposures to environmental toxicants can have detrimental effects on several aspects of human male reproduction: fertility, sexual function, hormone status, and pregnancy/birth outcomes. However, no simple prescreening methods are available for reliably identifying potential hazards; questionnaires alone are relatively imprecise and inefficient in the absence of field data. Multidisciplinary field studies are required that include detailed exposure information, health and reproductive histories, physical examinations, semen analyses, and possibly, hormone analyses. Semen analysis is a critical component of field studies for evaluating two aspects of male reproduction: 1) changes in sperm or seminal content, which may be indicative of adverse effects on the male reproductive system with possible implications for fertility potential; and 2) defects in sperm DNA or chromosomes, which may be associated with subsequent changes in viability during embryonic development and health risks to the offspring. Semen analyses may be tiered: 1) initially, each semen study may include conventional semen assays (concentration, motility, and morphology) as well as specific biomarkers indicated by the health effect of concern in the study cohort: and 2) archived samples (i.e., frozen, videotaped, or smeared) may be utilized in later second-tier analyses to further characterize specific findings. Before initiating any field study, it is cost effective to critically evaluate the suitability of the cohort by confirming exposure and determining that there are adequate numbers of male participants in each exposure category. Such evaluations must be based on the statistical sensitivities of the specific tissue biomarkers and health endpoints for detecting changes. This article summarizes the components of the ideal field study and identifies research needs for improving field studies of male effects and for understanding the mechanisms of male reproductive toxicity.

Excavating and treating the contaminated soil may not be practical or even possible if the affected zone is relatively deep. Merely pumping groundwater has proven to be ineffective because huge amounts of water must be flushed through the contaminated area to clean it; even then the contaminants may not be completely removed. Due to the low solubility of most common contaminants, such pump and treat systems can be expected to take decades to centuries to actually clean a site. Today, many sites are required to pump and treat contaminated groundwater even though there is no expectation that the site will be cleaned. In these cases, the pumps simply control the spread of the contaminant, while requiring a continuous flow of money, paperwork, and management attention. Although pump and treat systems are relatively inexpensive to operate, they represent along term cost. Most importantly, they rarely remove enough contaminant to change the property's status. Although a pump and treat system can offer compliance in a regulatory sense, it doesn't solve the site's liability problem. Thermal methods promise to solve this dilemma by actually cleaning a property in a short time period, thus limiting the period of liability. This may involve cleaning a site to closure during the initial contaminant-removal phase, or removal of the majority of the contaminant so that natural processes such as bioremediation can return the site to pristine condition over a period of years, without further owner intervention. Today's regulatory environment encourages this approach through efforts such as the brownfields initiatives. In either case, this requires a strong commitment on the part of the site owner. Most if not all the cleanup occurs within the first year or so, and nearly all the cost. In our experience, the total cleanup cost is still significantly smaller than with conventional methods. The real benefit is the cleanup and thus the removal of liability within a realistic time frame.

Preliminary results of hydrothermal oxidation using both dissolved O (sub 2) gas and mineral oxidants present naturally in soils (e.g., MnO (sub 2) ) demonstrate that TCE, TCA, and even PCE can be rapidly and completely degraded to benign products at moderate conditions, easily achieved in thermal remediation. Polycyclic aromatic hydrocarbons (PAHS) have an even larger thermodynamic driving force favoring oxidation, and they are also amenable to in situ destruction. Today, the principal treatment methods for chlorinated solvent- and PAH-contaminated soil are to remove it to landfills, or incinerate it on site. The most effective method for treating ground water, Dynamic Underground Stripping (Newmark et al., 1995), still involves removing the contaminant for destruction elsewhere. Hydrous pyrolysis/oxidation would eliminate the need for long-term use of expensive treatment facilities by converting all remaining contaminant to benign products (e.g., carbon dioxide, water, and chloride ion). The technique is expected to be applicable to dense non-aqueous phase liquids (DNAPLS) and dissolved organic components. Soil and ground water would be polished without bringing them to the surface. This would dramatically decrease the cost of final site closure efforts. Large-scale cleanup using hydrous pyrolysis/oxidation may cost less than $10/yd. The end product of hydrous pyrolysis/oxidation is expected to be a clean site. The delivery concept for hydrous pyrolysis/oxidation utilizes the established experience in heating large volumes of ground developed in the Dynamic Underground Stripping Demonstration (Newmark et al., 1995). Steam and possibly oxygen are injected together, building a heated, oxygenated zone in the subsurface. When injection is halted, the steam condenses and contaminated groundwater returns to the heated zone. It mixes with the condensate and oxygen, destroying any dissolved contaminants. This avoids many of the mixing problems encountered in other in situ oxidation schemes. In other oxidation schemes, an oxidizing reagent is injected into the subsurface resulting in the displacement of the contaminant. Without a return process such as the steam condensation, the contaminant and oxidant never mix. Using hydrous pyrolysis/oxidation, DNAPLs and dissolved contaminants may be destroyed in place, without surface treatment. This will improve the rate and efficiency of remediation by rendering the hazardous materials into benign ones via a completely in situ process. Because the subsurface is heated during this process, hydrous pyrolysis/oxidation also takes advantage of the large increase in mass transfer rates which make contaminant more available for destruction, such as increased diffusion out of silty sediments. Many remediation processes are limited by the access of the reactants to the contaminant, making mass-transfer limitations the bane of remediation efforts in low-permeability media.

Most VEA installation methods in current use are not economic for environmental applications. The cone penetrometer technology (CPT) can provide an economic and relatively non-intrusive installation method. However, a VEA with deployable and properly functioning electrodes was required. Results of the design, installation and testing of CPT VEAs are reported in this paper. Several designs were developed and bench tested for use with the CPT. After initial field installation studies, one design was chosen for further testing at the DOE Hanford Site. Four VEAs were each pushed to 100 feet in 4 days. To test the CPT VEAs, an infiltration experiment was conducted with cross VEA tomographic data collected for three vertical planes. These data were processed using the electrical resistivity tomography code developed by Lawrence Livermore National Laboratory (LLNL). Tomographic images for each vertical plane tracked the subsurface resistivity changes associated with the migrating fluid. It is concluded from these test results that the CPT is a viable method for installing VEAs. The VEAs were rapidly and economically installed to the maximum depth required, data of adequate quality were obtained and tomographic images from the infiltration experiment verified that the CPT VEAs provide viable ERT data.

The ERT data sets, collected between five pairs of adjacent wells using an array of electrodes located in 4 boreholes, have been previously interpreted with a 2D algorithm (Ramirez and Daily, 1994) to map the changes in conductivity in a clay layer located in the vadose zone over a period of approximately 2 months (before, during and after electrical heating). The objective of this work is to show the usefulness of a new 3D ERT interpretation technique for a complete monitoring of a real 3D underground process. Heating causes moisture content, temperature, and fluid conductivity changes, all of which affect electrical resistivity, and the successful application of ERT provides a three-dimensional view of the subsurface resistivity or conductivity distribution. This information helps us to understand the interaction between heating and the heterogeneous subsurface, the effects of heating on fluid flow and on contaminant removal. The reconstruction of both the background resistivity and of the changes over time, caused by the combined effects of moisture redistribution and heating caused by SPOH and vapor extraction, is enhanced by the 3D interpretation.

A single 4 kW heater, placed in a horizontal borehole, was turned on August, 1996 and will continue to heat the rockmass until April 1997. Of the several thermal, mechanical and hydrological measurements being used to monitor the rockmass response, electrical resistance tomography (ERT) is being used to monitor the movement of liquid water with a special interest in the movement of condensate out of the system. Four boreholes, containing a total of 30 ERT electrodes, were drilled to form the sides of a 30 foot square with the heater at the center and perpendicular to the plane. Images of resistivity change were calculated using data collected before and during the heating episode. The changes recovered show a region of decreasing resistivity approximately centered around the heater. The size this region grows with time and the resistivity decreases become stronger. The changes in resistivity are caused by both temperature and saturation changes. The observed resistivity changes suggest that the rock adjacent to the heater dries as heating progresses. This dry region is surrounded by a region of increased saturation where steam recondenses and imbibes into the rock.

We experimentally investigated the effect of reduced grain size on the solid-state flow of water ice I, a principal component of the asthenospheres of many icy moons of the outer solar system, using techniques new to studies of this deformation regime. We fabricated fully dense ice samples of approximate grain size 2 + or - 1 mu m by transforming "standard" ice I samples of 250 + or - 50 mu m grain size to the higher-pressure phase ice II, deforming them in the ice II field, and then rapidly releasing the pressure deep into the ice I stability field. At T or = 220 K the elongation of the grains is so pronounced that the samples appear finely banded, with aspect ratios of grains approaching 50:1. The anisotropic growth of these crystallographically oriented neoblasts likely contributes to progressive work hardening observed during the transient stage of deformation. We have also documented remarkably similar microstructural development and weak mechanical behavior in fine-grained ice samples partially transformed and deformed in the ice II field.

Constraints from the global atmospheric electric circuit AN - 16455107; 4380411 AB - The global atmospheric electric circuit can be used to constrain the total amount of NO sub(x) produced by lightning (LNO sub(x)). Since the global atmospheric electric circuit is regulated by global thunderstorm activity and, more specifically, global lightning currents, we use the global electric circuit to quantify and place limits on the total amount of energy available from lightning. Using a production rate of 10 times 10 super(16) molecules NO/J, we have calculated the global LNO sub(x) production on monthly, annual, and interannual time scales from 1983 to 1991. The 8-year mean production rate is found to be 13.2 Tg N/yr and agrees with the independent estimate derived in part 1 of this study (12.2 Tg N/yr), which is based on lightning physics and global lightning distributions. After considering the various uncertainties in these calculations, we conclude that the annual production rate of NO sub(x) from lightning cannot be less than 5 nor more than 25 Tg N/yr. JF - J.

Global distribution based on lightning physics AN - 16452667; 4380410 AB - This paper begins a study on the role of lightning in maintaining the global distribution of nitrogen oxides (NO sub(x)) in the troposphere. It presents the first global and seasonal distributions of lightning-produced NO sub(x) (LNO sub(x)) based on the observed distribution of electrical storms and the physical properties of lightning strokes. We derive a global rate for cloud-to-ground (CG) flashes of 20-30 flashes/s with a mean energy per flash of 6.7 times 10 super(9) J. Intracloud (IC) flashes are more frequent, 50-70 flashes/s but have % of the energy of CG strokes and, consequently, produce significantly less NO sub(x). It pears to us that the majority of previous studies have mistakenly assumed that all lightning flashes produce the same amount of NO sub(x), thus overestimating the NO sub(x) production by a factor of 3. On the other hand, we feel these same studies have underestimated the energy released in CG flashes, resulting in two negating assumptions. For CG energies we adopt a production rate of 10 times 10 super(16) molecules NO/J based on the current literature. Using a method to simulate global lightning frequencies from satellite-observed cloud data, we have calculated the LNO sub(x) on various spatial (regional, zonal, meridianal, and global) and temporal scales (daily, monthly, seasonal, and interannual). Regionally, the production of LNO sub(x) is concentrated over tropical continental regions, predominantly in the summer hemisphere. The annual mean production rate is calculated to be 12.2 Tg N/yr, and we believe it extremely unlikely that this number is less than 5 or more than 20 Tg N/yr. Although most of LNO sub(x) is produced in the lowest 5 km by CG lightning, convective mixing in the thunderstorms is likely to deposit large amounts of NO sub(x) in the upper troposphere where it is important in ozone production. On an annual basis, 64% of the LNO sub(x) is produced in the northern hemisphere, implying that the northern hemisphere should have natural ozone levels as much as 2 times greater than the southern hemisphere, even before anthropogenic influences. The amount of O sub(3) produced from this NO sub(x) is expected to exceed the stratospheric source by a factor of 1.5, and thus the hemispheric asymmetry in LNO sub(x) would lead to a significant excess of northern hemisphere O sub(3) even in the preindustrial troposphere.

In this assay, the cells from the irradiated embryo exhibit a competitive cell proliferation disadvantage when they are challenged by direct cell-cell contact with cells from a normal embryo in an aggregation chimera. Here, six pregnant CD-1 mice received a total of 1.85 TBq tritiated thymidine (TdR) delivered by multiple intraperitoneal injections during days 13-15 postconception. Six more pregnant mice were sham-injected to provide control embryos. Sixty randomly selected female progeny were mated at 47 days of age and their 4-cell embryos tested in the chimera assay. The mean proliferation ratio (PR, number of cells from the experimental embryo divided by total cell number of the chimera) for experimental chimeras was 0.45 plus or minus 0.02 SE (n=43), which was significantly less than the mean PR of 0.49 plus or minus 0.01 SE (n=47; p=0.02) for control chimeras. This entire experiment was repeated, with similar results. A comparison for TdR confined to the nucleus (i.e., mean beta -ray range is only 0.7 mu m) with the relationship for uniform irradiation by 137Cs gamma -rays demonstrates that these two very different modes of dose delivery produce essentially identical PRs. These results in vivo suggest a nuclear DNA target for embryonic cell proliferation disadvantage consistent with our previous findings in vitro.

AN - 78962915; 9129321 AB - Carcinogenic and mutagenic heterocyclic aromatic amines (HAA) are natural products often present at ng/g levels in muscle meats when they are cooked at temperatures over 150 degrees C. Using solid-phase extraction and high performance liquid chromatography (HPLC) with photodiode array UV detection, samples were analyzed for the following heterocyclic amines: DiMeIQx (2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline); IQ (2-amino-3-methylimidazo[4,5-f]quinoline); MelQx (2- amino-3,8-dimethylimidazo[4,5-f]quinoxaline); and PhIP (2-amino-1-methyl- 6-phenylimidazo[4,5-b]pyridine). Quality control samples, analyzed periodically over two years in a blind study, show relative standard deviations ranging from 22 to 38% for the compounds found, variations typical for analysis at ng/g levels. Amounts range from undetectable levels (less than 0.1 ng/g) to hundreds of ng/g of PhIP for frying or grilling at high meat surface temperatures. Beef, chicken, pork and lamb can all have greater than 10 ng/g of PhIP. Ground chicken breast meat has lower amounts of heterocyclic amines than intact muscle pieces of the same size cooked identically. Restaurant prepared samples that we analyzed contained undetectable levels up to 14 ng/g total heterocyclic amines for a beef steak sample. Not extracted with the above method are related mutagenic heterocyclic amines, which have been reported in cooked foods in our laboratory and others. Method development using ion exchange on an SCX solid-phase extraction cartridge shows promise in providing a method for the quantitation of these mutagenic dimethyl-, trimethyl- and furo-imidazopyridines where a practical analysis method is needed.

By necessity, early studies have ignored important field properties, parameters, and processes that control the ultimate success of in situ bioremediation of contaminated groundwater. This paper presents a bioengineering systems approach that examines the impact of some of these field variables on common bioremediation practices. Using simple systems, the niche of biostimulation is shown to be aquifers with high contaminant sorption. A novel gas-phase biostimulation filter and a novel resting-state bioaugmentation/biofilter approach which show promise for effective field implementation are discussed.

AN - 78900265; 9056499 AB - Cancer risk assessments for trichloroethylene (TCE) based on linear extrapolation from bioassay results are questionable in light of new data on TCE's likely mechanism of action involving induced cytotoxicity, for which a threshold-type dose-response model may be more appropriate. Previous studies have shown that if a genotoxic mechanism for TCE is assumed, algebraic methods can considerably simplify the use of physiologically based pharmacokinetic (PBPK) models to estimate virtually safe environmental concentrations for humans based on rodent cancer-bioassay data. We show here how such methods can be extended to the case in which TCE is assumed to induce cancer via cytotoxicity, to estimate environmentally safe concentrations based on rodent toxicity data. These methods can be substituted for the numerical methods typically used to calculate PBPK-effective doses when these are defined as peak concentrations. We selected liver and kidney as plausible target tissues, based on an analysis of rodent TCE-bioassay data and on a review of related data bearing on mechanism. Tumor patterns in rodent bioassays are shown to be consistent with our estimates of PBPK-based, effective cytotoxic doses to mice and rats used in these studies. When used with a margin of exposure of 1000, our method yielded maximum concentration levels for TCE of 16 ppb (87 micrograms/m3) for TCE in air respired 24 hr/day, 700 ppb (3.8 mg/m3) for TCE in air respired for relatively brief daily periods (e.g., 0.5 hr while showering/bathing), and 210 micrograms/liter for TCE in drinking water assuming a daily 2-liter ingestion. Cytotoxic effective doses were also estimated for occupational respiratory exposures. These estimates indicate that the current OSHA permissible exposure limit for TCE would produce metabolite concentrations that exceed an acute no observed adverse effect level for hepatotoxicity in mice. On this basis, the OSHA TCE limit is not expected to be protective.

We then discuss how the proposed extinction mechanisms may relate to the environmental consequences of asteroid and comet impacts in general. Our chief goal is to provide relatively simple prescriptions for evaluating the importance of impacting objects over a range of energies and compositions, but we also stress that there are many uncertainties. We conclude that impacts with energies less than about 10 Mt are a negligible hazard. For impacts with energies above 10 Mt and below about 10 (super 4) Mt (i.e., impact frequencies less than one in 6 X 10 (super 4) years, corresponding to comets and asteroids with diameters smaller than about 400 m and 650 m, respectively), blast damage, earthquakes, and fires should be important on a scale of 10 (super 4) or 10 (super 5) km (super 2) , which corresponds to the area damaged in many natural disasters of recent history. However, tsunami excited by marine impacts could be more damaging, flooding a kilometer of coastal plain over entire ocean basins. In the energy range of 10 (super 4) -10 (super 5) Mt (intervals up to 3 X 10 (super 5) years, corresponding to comets and asteroids with diameters up to 850 m and 1.4 km, respectively) water vapor injections and ozone loss become significant on the global scale. In our nominal model, such an impact does not inject enough submicrometer dust into the stratosphere to produce major adverse effects, but if a higher fraction of pulverized rock than we think likely reaches the stratosphere, stratospheric dust (causing global cooling) would also be important in this energy range. Thus 10 (super 5) Mt is a lower limit where damage might occur beyond the experience of human history. The energy range from 10 (super 5) to 10 (super 6) Mt (intervals up to 2 X 10 (super 6) years, corresponding to comets and asteroids up to 1.8 and 3 km diameter) is transitional between regional and global effects. Stratospheric dust, sulfates released from within impacting asteroids, and soot from extensive wild-fires sparked by thermal radiation from the impact can produce climatologically significant global optical depths of the order of 10. Moreover, the ejecta plumes of these impacts may produce enough NO from shock-heated air to destroy the ozone shield. Between 10 (super 6) and 10 (super 7) Mt (intervals up to 1.5 X 10 (super 7) years, corresponding to comets and asteroids up to 4 and 6.5 km diameter), dust and sulfate levels would be high enough to reduce light levels below those necessary for photosynthesis. Ballistic ejecta reentering the atmosphere as shooting stars would set fires over regions exceeding 10 (super 7) km (super 2) , and the resulting smoke would reduce light levels even further. At energies above 10 (super 7) Mt, blast and earthquake damage reach the regional scale (10 (super 6) km (super 2) ). Tsunami cresting to 100 m and flooding 20 km inland could sweep the coastal zones of one of the world's ocean basins. Fires would be set globally. Light levels may drop so low from the smoke, dust, and sulfate as to make vision impossible. At energies approaching 10 (super 9) Mt (>10 (super 8) years) the ocean surface waters may be acidified globally by sulfur from the interiors of comets and asteroids. The Cretaceous-Tertiary impact in particular struck evaporate substrates that very likely generated a dense, widespread sulfate aerosol layer with consequent climatic effects. The combination of all of these physical effects would surely represent a devastating stress on the global biosphere. Copyright 1997 by the American Geophysical Union.

AN - 79513119; 9435878 AB - Deletion and insertion mutations have been found to be a major component of the in vivo somatic mutation spectrum in the hypoxanthine phosphoribosyltransferase (hprt) gene of T-lymphocytes. In a population of 172 healthy people (average age, 34; mutant frequency, 10.3 x 10(-6)), deletion/insertion mutations constituted 41% (89) of the 217 independent mutations, the remainder being base substitutions. Mutations were identified by multiplex PCR assay of genomic DNA for exon regions, by sequencing cDNA, or sequencing genomic DNA. The deletion and insertion mutations were divided among +/- 1 to 2 basepair (bp) frameshifts (14%, 30), small deletions and insertions of 3-200 bps (13%, 28), large deletions of one or more exons (12%, 27), and complex events (2%, 4). Frameshift mutations were dominated by -1 bp deletions (21 of 30). Exon 3 contained five frameshift mutations in the run of 6 Gs, the only site in the coding region with multiple frameshift mutations, possibly caused by strand dislocation during replication. Both endpoints were sequenced for 23 of the 28 small deletions/insertions including two tandem duplication events in exon 6. More small deletions (8/28), possibly mediated by trinucleotide repeats, occurred in exon 2 than in the other exons. Large deletions included total gene deletions (6), exon 2 + 3 deletions (4), and loss of multiple (9) and single exons (8) in genomic DNA. The diverse mutation spectrum indicates that multiple mechanisms operated at many different sequences and provides a resource for examination of deletion mutation.

AN - 79413522; 9368303 AB - In this article we discuss examples of challenging problems in retrospective dosimetry and describe some promising solutions. The ability to make measurements by accelerator mass spectrometry and luminescence techniques promises to provide improved dosimetry for regions of Belarus, Ukraine and Russian Federation contaminated by radionuclides from the Chernobyl accident. In addition, it may soon be possible to resolve the large neutron discrepancy in the dosimetry system for Hiroshima through novel measurement techniques that can be used to reconstruct the fast-neutron fluence emitted by the bomb some 51 years ago. Important advances in molecular cytogenetics and electron paramagnetic resonance measurements have produced biodosimeters that show potential in retrospective dosimetry. The most promising of these are the frequency of reciprocal translocations measured in chromosomes of blood lymphocytes using fluorescence in situ hybridization and the electron paramagnetic resonance signal in tooth enamel.

Some examples include the drill bit as a source for an inverse VSP (IVSP) experiment, or a vibroseis experiment where the electronic vibroseis signal is significantly different than that of the ground motion beneath the truck, or a self-imaging oil field where the pumps or steam front act as seismic sources. One might think that these data, where the excitation time or wavelet shape are unknown, cannot be migrated to precisely image the subsurface reflectors. Here, we show that such data can be migrated by first taking the autocorrelation of the data, and then backpropagating the autocorrelograms in reverse time. Synthetic tests show that the reflector locations can still be accurately imaged, but the penalty is that the dynamic range of the migrated autocorrelogram image can be degraded by interference from "virtual multiples" in the autocorrelograms. Thus autocorrelogram migration is not recommended as a replacement for seismogram migration unless there is insufficient knowledge of the source wavelet.

We show that epsilon lies in the range -3/8 < or = epsilon < or = 1/2[(v (super 2) (sub p) )(v (super -2) (sub p) ) -1], for finely layered media having constant density; smaller positive and all negative values of occur for media with large fluctuations in the Lame parameter lambda . We show that sign (delta ) = sign ([v (super -2) (sub p) ) - (v (super -2) (sub s) ) (v (super 2) (sub s) /v (super 2) (sub p) )) for constant density media, so delta can be either positive or negative. Among all theoretically possible random media, positive and negative delta are equally likely in finely layered media limited to two types of constituent layers. Layered media having large fluctuations in Lame lambda are the ones most likely to have positive delta . Since Gassmann's results for fluid-saturated porous media show that the effects of fluids influence only the lambda Lame constant, not the shear modulus mu , these results suggest that positive occurring together with positive but small epsilon may be indicative of changing fluid content in layered earth.

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.

However, in situ (super 208) Pb/ (super 232) Th dating of monazite inclusions in garnet indicates that peak metamorphic recrystallization of the MCT footwall occurred in this portion of the central Himalaya at only ca. 6 Ma. The apparent inverted metamorphism appears to have resulted from activation of a broad shear zone beneath the MCT which tectonically telescoped the young metamorphic sequence. This explanation may resolve some outstanding problems in Himalayan tectonics, such why the MCT and not the more recently initiated thrusts marks the break in slope of the present day mountain range. It also renders unnecessary the need for exceptional physical conditions (e.g., high shear stress) to explain the generation of the Himalayan leucogranites.

Application of this methodology to the chronology of active tectonics is an emerging area of research, allowing millennial slip-rates and earthquake recurrence intervals to be constrained. Field mapping, SPOT image analysis, and Be-10 and Al-26 dating of quartz-rich surface and subsurface samples have been used to assess the style, magnitude, and rate of Late Quaternary motion on strike-slip, thrust and normal faults along the margin of the Tibetan Plateau. Datable features are largely fluvial/alluvial surfaces deposited at the base of rapidly uplifted mountain belts. In these geomorphic settings the contribution of inherited cosmogenic nuclides appears to be small relative to the total cosmogenic nuclide abundance. Lateral slip-rates are determined from measured offsets of terrace risers combined with ages based on surface exposure dates. Riser ages are constrained to be older than lower-lying inset terraces, which represent the time of fluvial abandonment. Uplift rates are derived in a similar manner from measured vertical offsets of terraces combined with the terrace age. Our results show that pre-Holocene features are preserved in some of the active regions bounding the plateau, but that the youngest, best preserved offsets are Holocene. For instance, along the Xidatan segment of the Kunlun fault, we have identified two terrace risers offset by 24+ or -3 and 33+ or -3 meters with corresponding Be-Al ages of 1778+ or -476 and 2940+ or -645 years, respectively, yielding a slip-rate of 12.6+ or -1.7 mm/yr. Along the eastern segment of the fault, the lateral moraine of an extinct glacier was found to be displaced 180+ or -20 m by the main strand of the fault. The offset is constrained by a C-14 age of 11200+ or -200 years from a high-level terrace dammed by the moraine. This age implies to first order a slip-rate of 13+ or -5 mm/yr, comparable to the rate on the Xidatan segment. These rates are similar to that obtained with C-14 dating of geomorphological offsets by Zhao et al.

Using the production rates of Nishiizumi et al. (1996) the minimum age of the youngest set of LGM moraines is approximately 14.4 ka while that of next oldest moraines is approximately 19.2 ka. However, this apparently contradicts the minimum limiting age of the stratigraphically and morphologically younger Manachaque moraines ( approximately 16,000 cal yr B.P.) and the minimum age of approximately 21,500 cal yr B.P. and 19,700 14C yr B.P. for the Rurec moraines. Because we know that these deposits are associated with the LGM and we know the timing of the LGM in the range, we calculate new effective production rates for 10Be and 26Al based on the assumptions that the youngest set of dated moraines: (a) were formed at the LGM (17,500 cal yr B.P.) and (b) experienced neither prior exposure nor significant post-depositional erosion. Our new as effective production rates for low latitude settings recalculated to high latitude and sea level, are: 4.53+0.50 and 28.9+3.2 atoms/g-quartz for 10Be and 26Al, respectively, with 26Al/10Be of 6.38+1.0, integrated over the last 17,500 years. Using these new production rates the ages from all the moraines cluster into three groups at 17.5 (assumed), approximately 24.0 and approximately 140 ka. The timing of the advances recorded in the Cordillera Blanca closely match those of Heinrich events 1, 2, and 7 (16.5, 23.0 and 130 ka) and changes in isotopic compositions from marine records. These new data suggest that warming at the end of the LGM was synchronous and global in nature. However, recent models of climatic teleconnections between the Atlantic and Pacific basins can not explain this climatic link between the northern and southern hemispheres.

This was based, in part, on the assumption that the most-recent rupture occurred in 1836. Recent work suggests the 1836 earthquake was not on the Hayward fault, thereby removing constraints on elapsed time and segmentation, which are two critical parameters for assessing future fault behavior. The fault traverses a highly urbanized area, which presents unique problems for conducting paleoseismologic research. Most of the northern Hayward fault is covered by roads, buildings, and/or landslides. Less than 5% of the trace crosses undisturbed ground, severely limiting where paleoseismologic data can be obtained. Our approach to identifying viable paleoseismic sites along the northern Hayward fault involved feasibility studies at multiple sites, followed by increasingly detailed studies at fewer and fewer sites. Our initial air-photo analysis yielded about 20 potential sites along the northern Hayward fault. Field reconnaissance and compilation of existing site-specific geologic and historical data narrowed our focus to seven sites. Completion of shallow boreholes and detailed mapping show that only four of these sites have (1) surface or subsurface data constraining the location of the main fault strand, (2) datable deposits that likely provide a piercing line or preserve evidence of recent surface ruptures, (3) minimal cultural disturbance or logistical constraints, and (4) landowners amenable to research-level studies. These sites are the only previously unstudied localities remaining on the northern Hayward fault that have the potential to provide well-constrained paleoseismic data. Current studies at these sites include exploratory trenching and, because of limited time windows imposed by trenching in public spaces, "real-time" radiocarbon dating to provide results while trenches are being logged and interpreted.

By measuring not only the rate of disappearance of TCE, but also the rate of appearance of carbon dioxide and chloride ion we were able to monitor mass balances and confirm that 'mineralization' was the ultimate reaction. We used dilute buffer solutions to fix pH and stoichiometrically sufficient amounts of dissolved oxygen to make the reactions zero-order in oxygen. Using standard chemical kinetic methods, we spanned two orders of magnitude in initial TCE concentration and used the resulting double-log plot vs. initial rate (regressed using both linear and polynomial fits) to determine the rate constant and "true" reaction order (i.e., with respect to concentration, not time). By determining rate constants over the temperature interval 343-373K, we determined the Arrhenius activation energy for the reaction. We also investigated the effect of buffer ligand concentration and type (phosphate, borate, acetate, carbonate, sulfate), ionic strength, specific electrolytes, and pH on the rate of TCE aqueous oxidation. The aqueous oxidation reaction rate was found to be pH dependent (both acid and base catalyzed) over the pH range pH 2 to pH 10 and strongly inhibited by high dissolved bromide concentration.

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.

High resolution SPOT images and field mapping have been used to identify geomorphic features displaced along the Karakax Valley segment of the fault (36N, 78E). Indirect age estimates based on climatic arguments led Peltzer et al. (1989) to infer a Quaternary slip-rate of 20 mm/yr on this segment of the ATF. An alluvial fan preserving two abandoned inset terraces and associated risers has been investigated using in-situ Be-10 and Al-26 dating of surface and subsurface samples to constrain the millennial slip-rate on the Karakax Valley segment of the ATF. Subsurface samples from the upper inset terrace display an exponential decrease in nuclide abundance with depth, consistent with secondary neutron attenuation. The depth profile extrapolates to a surface age of approximately 120 ka, and asymptotically approaches zero at a depth of 2m. The very low cosmogenic nuclide concentrations at depth are indicative of negligible nuclide inheritance and thus suggest rapid exhumation and sediment transport. The lower inset terrace preserves an offset of (super *) 140 m. Model ages for surface cobbles range from 6-32 ka. Subsurface samples of the lower terrace do not display a simple exponential depth profile. Rather, the depth profile is bounded by a 6 ka isochron. In light of the evidence from the upper terrace that the system can deliver material with little inheritance and of the absence of any sign of post-depositional reworking of the lower terrace, we interpret subsurface samples with ages greater than 6 ka to have been locally derived by excavation and redeposition of material from the adjacent 120 ka terrace. Combined with the observed offset, the bounding 6 ka age yields a slip-rate of approximately 25 mm/yr. Displacement along the western terminus of the ATF system is distributed among the Karakax Valley segment and other left-lateral features to the south (the Gozha and Long Mu Co faults). This implies slip-rates of greater than 25 mm/yr on the central segment of the ATF which is represented by a single major fault strand.

Such information can be used to trace the evolution of the Tiwi geothermal field through time. The React geochemical modeling code was used to simulate the effects of isothermal and isoenthalpic boiling, conductive cooling and heating, and incorporation of condensed steam, on fluids from the Matalibong area. Predicted mineral stabilities were used to identify mineral indicators for each process. Calcite and anhydrite precipitation were favored by conductive heating, while illite precipitation was favored when condensed steam was added to the reservoir fluid. Reconstructed downhole fluids from borehole Mat-25 are acidic and are consistent with the presence of illite as the latest alteration mineral in veins. The processes of isothermal and isoenthalpic boiling could be differentiated from conductive cooling by the presence of epidote and/or calcite during boiling, and illite during cooling. Both boiling and cooling favored precipitation of quartz, K-feldspar, wairakite, and pyrite.

Previous studies have placed first-order constraints on upper mantle velocities but relied on data recorded almost exclusively at stations outside of the plateau. We improve resolution by using 40 events recorded at stations within the Tibetan Plateau. We combine these data with observations obtained from the International Seismological Centre (ISC) to extend our coverage by including Pn arrivals from 85 additional plateau events, relocated in previous studies, and recorded at stations in and around the Tibetan Plateau. We use synthetic travel time data to evaluate the resolution of our data set. The observations provide good resolution to about 1 degrees over most of the plateau and surrounding regions. Our results show average Pn velocities that are about 3% lower in the northern plateau relative to the southern plateau. These variations correlate well with major tectonic features and previous geophysical observations. In the Qiangtang terrane of the northern plateau, an area known to be inefficient for Sn propagation, Pn is slow relative to both the plateau south of the Banggong-Nujiang suture and the tectonically stable Tarim basin north of the plateau. This is strong evidence for the existence of partial melt within the uppermost mantle beneath the northern Tibetan Plateau. However, when laboratory estimates of relationships between temperature, velocity, and attenuation are applied, a relatively small temperature variation (240 degrees to 370 degrees C) is required to explain our Pn velocity observations. When combined with geochemical constraints from volcanics in the northern plateau, our results strongly suggest that the mantle lid is intact beneath the northern plateau. This result would preclude tectonic models involving wholesale delamination of the mantle lithosphere in the northern Tibetan Plateau. Copyright 1997 by the American Geophysical Union.

PAINT/DAPI analysis employs multicolor fluorescence in situ hybridization painting plus DAPI staining to detect both stable and unstable chromosomal aberrations at first-cleavage metaphase of the zygote. High levels of chromosomally defective zygotes were detected after mating at all postmeiotic stages (20-190-fold, P < 0.001). Early spermatozoa (6.5 d post-treatment) were the most sensitive, with 76% of the zygotes carrying cytogenetic defects. A significant 10-fold increase was also detected 27.5 d post-treatment, indicating that AA had a cytogenetic effect on meiotic stages. PAINT/DAPI analysis revealed that: 1) AA-induced chromosomal breaks occurred at random, and 2) the frequencies of symmetrical and asymmetrical exchanges were similar at all mating days, except 9.5 d after AA treatment, where significantly (P < 0.02) more asymmetrical aberrations were found. Furthermore, the proportions of zygotes carrying unstable and stable chromosomal aberrations followed a similar post-treatment time course as the proportions of dominant lethality among embryos and heritable translocations among offspring. These findings indicate that PAINT/DAPI analysis of zygotic metaphases is a promising method for detecting male germ cell mutagens capable of inducing chromosomal aberrations and for evaluating the associated risks for embryonic loss and balanced translocations at birth.

Irradiation occurred 24 hr after culture initiation, and metaphase chromosomes were prepared 2, 3, 4, and 5 days later. Chromosomes 1, 2, and 4 were painted in unique colors and scored for structural aberrations. Dicentric chromosomes and acentric fragments diminished rapidly with time, as expected. Translocations exhibited greater persistence, but still showed a reduction in frequency, reaching a plateau of approximately 65 and 55% of their initial values, 4 days after exposure to 1 and 2 Gy, respectively. An exponentially declining model was fit to the combined dicentric, acentric fragment, and translocation frequencies, which showed that all three aberration types declined at equivalent rates. The frequencies of dicentrics and fragments declined to a plateau of zero, while translocations reached a plateau at frequencies significantly greater than zero. The decline in translocations with time is inconsistent with prevailing theoretical expectations, but is consistent with a model where some translocations are fully stable (persistent) and some are unstable (not persistent) through cell division. These results may have implications for radiation biodosimetry in humans.

Two shower nozzles generating droplet sizes of 1800 and 300 um diameter water to air were used and a standard shower nozzle. The nozzles were operated at 35 or 45C. Water-to-air efficiencies of chloroform and aerosol concentrations were compared. The water-to-air transfer efficiencies were 0.65, 0.80 and 0.90, for standard, 300 um and 1800 um nozzles, respectively. The water-to-air efficiencies were shown to have marginal success in predicting measured air concentrations. Discrepancies were observed with the highest aerosol concentrations and when peak aerosol concentrations occurred between 2 and 4 minutes of a 10 minute shower.

Measurements were made for a range of frequencies. Dry and saturated resistivities could differ by more than four orders of magnitude. The impedance arcs observed in frequency-dependent measurements indicated that the overall electrical response of the rock arose from at least three conduction mechanisms: through adsorbed water on solid surfaces; through isolated pockets of water; and through bulk water. Their relative contributions varied with saturation. A continuous bulk water film was apparent at saturations as low as 35 per cent. Permeability predicted from electrical measurements, experimentally obtained values, and microstructural parameters using the Kozeny-Carmen relation showed reasonable agreement. Estimates of cation exchange capacity based on electrical properties were also consistent with published values. There are 31 references.

N1 - Last updated - 2011-12-12 ER - TY - JOUR T1 - Thermophilic biodegradation of BTEX by two consortia of anaerobic bacteria AN - 13621684; 199802191 AB - Two thermophilic microbial consortia, ALK-1 and LLNL-1, capable of utilizing benzene, toluene, ethylbenzene and the xylenes (BTEX), were isolated and characterized. All studies were conducted anaerobically in serum bottles using a formulated mineral salts-BTEX medium. Biodegradation of BTEX compounds was quantified by measuring their disappearance from the gas in the headspace in 14 d at 50C, 60C and 70C. The lack of difference between killed cell cultures and sulphate ion controls suggested that biodegradation was linked to sulphate metabolism. Abiotic controls revealed that high temperature was a factor in biodegradation. Similar trends occurred at each temperature, with most biodegradation occurring between 4-7 d. There was higher sulphate reduction at 50C, which was demonstrated to be the optimal temperature for biodegradation (compared to 60C and 70C). This was coupled with significant growth at 50C, measured by an increase in cellular protein of 16 mg per litre for ALK-1 and 11 mg per litre for LLNL-1. The metabolism of benzene and toluene by the 2 consortia was demonstrated by the incorporation of radioactively-labelled substrates. BTEX provides a carbon source for thermophiles and serves as electron donors for sulphate reducers, which has practical implications for in-situ BTEX biodegradation. The study suggests that thermophilic sulphate-reducing bacteria are principally responsible for the biodegradation of aromatic petroleum hydrocarbons.

The warning times involved are short, from 0 to 30 seconds or so; consequently, most responses must be automated. The San Francisco Bay Area is particularly well suited for an EAS because (1) large earthquakes have relatively shallow hypocenters (10- to 20-kilometer depth), giving favorable ray-path geometries for larger warning times than deeper from earthquakes, and (2) the active faults are few in number and well characterized, which means far fewer geographically distributed strong motion sensors are (about 50 in this region). An EAS prototype is being implemented in the San Francisco Bay Area. The system consists of four distinct subsystems: (1) a distributed strong motion seismic network, (2) a central processing station, (3) a warning communications system and (4) user receiver and response systems. We have designed a simple, reliable, and inexpensive strong motion monitoring station that consists of a three-component Analog Devices ADXLO5 accelerometer sensing unit, a vertical component weak motion sensor for system testing, a 16-bit digitizer with multiplexing, and communication output ports for RS232 modem or radio telemetry. The unit is battery-powered and will be sited in fire stations. The prototype central computer analysis system consists of a PC dam-acquisition platform that pipes the incoming strong motion data via Ethernet to Unix-based workstations for dam processing. Simple real-time algorithms, particularly for magnitude estimation, are implemented to give estimates of the time since the earthquake's onset its hypocenter location, its magnitude, and the reliability of the estimate. These parameters are calculated and transmitted with frequent updates as an 80-character digital string sent from the central analysis computer to pagers throughout the Bay Area in less than 2 seconds. We anticipate that the commercial sector will supply numerous and varied warning receiver systems once an EAS is considered operational. We focus on two prototype demonstration systems: (1) a pager-driven closure switch for opening fire station doors and (2) a pager display sign showing an of warning packet information. We will discuss the specific design features alert message and a display of this prototype system.

At this facility, volatile organic contaminants (VOCs) are removed by air stripping, which raises the water pH, causing the deposition of calcium carbonate as calcite scale downstream. To evaluate the magnetic treatment technique, the ground water was passed through the Descal-A-Matic (super R) device before treatment by the air stripping unit, and the resulting scale formation and other water characteristics were compared with those found during a test with no water treatment and a test with chemical treatment with a polyphosphate additive. No beneficial effect was found when using the magnetic device.

This document provides a summary of field experiment results performed under a 15 m diameter steel tank mockup located at the Hanford Reservation, Washington, and of supporting numerical simulations. Two different leak events were created. About 3800 liters of saline solution were first released along a portion of the tank's edge and another 1900 liters were later released near the tank's center. The release rate averaged about 26 liters/hour for the leak on the tank's side and about 3.0 liters/hour for the center leak. Two-and three-dimensional tomographs were calculated using data collected before, during and after each spill. The tomographs mapped the spatial and temporal evolution of resistivity changes caused by the leak; as the solution penetrated the soil, readily detectable resistivity decreases were observed and used to map the associated plume. The results show that the metal tank has significant effects on the results obtained, primarily in reducing sensitivity to the leak. The field results indicate that the plume associated with these releases could be reliably detected after approximately 190 liters were released. Results are also shown where the metal tank and metal-cased boreholes are used as large electrodes. We use the field results to extrapolate how these techniques could be used to detect and locate leaks, and to delineate any resulting plumes from the underground storage tanks.

The coefficients of the matrix pore pressure and fracture pore pressure in their equation for the effective stress are shown to be identical to those which can be obtained from the constitutive equation approach of Berryman and Wang [1995]. Representative values for a fractured Berea sandstone show that a change in pore pressure within matrix blocks produces about 10% of the volume change resulting from an equal but opposite change in confining pressure, whereas the same change in pore pressure within fractures is about 90% as effective. A similar result is true for Westerly granite.

AN - 78716565; 9131015 AB - The complete hamster ERCC2 cDNA was constructed in a plasmid vector from clones of three overlapping reverse transcribed/polymerase chain reaction amplified fragments using unique restriction enzyme recognition sites within the regions of overlap. This complete cDNA insert was then cloned into a mammalian expression vector, pcD2E, and tested for function by the ability to confer UV resistance to the ERCC2 mutant CHO cell line UV5. Site-specific mutagenesis was used to introduce the G347-->A and G1844-->A changes resulting in the Cys116-->Tyr and Gly615-->Glu mutations previously identified in UV5 and UVL-13 (also an ERCC2 mutant CHO cell line), respectively. The 116Tyr and 615Glu plasmids each failed to confer UV resistance to UV5 or UVL-13 cells, respectively, demonstrating that the changes identified are indeed the causative mutations in UV5 and UVL-13.

AN - 78477302; 8887520 AB - Radioiodine released to the atmosphere from the accident at the Chernobyl nuclear power station in the spring of 1986 resulted in large-scale thyroid-gland exposure of populations in Ukraine, Belarus, and Russia. Because of the short half life of 131I (8.04 d), adequate data on the intensities and patterns of iodine deposition were not collected, especially in the regions where the incidence of childhood-thyroid cancer is now increasing. Results are presented from a feasibility study that show that accelerator-mass-spectrometry measurements of 129I (half life 16 x 106 y) in soil can be used to reconstruct 131I-deposition density and thus help in the thyroid-dosimetry effort that is now urgently needed to support epidemiologic studies of childhood-thyroid cancer in the affected regions.

AN - 78474280; 8882884 AB - Both structural and numerical chromosome aberrations in sperm represent important categories of paternally transmitted genetic damage. Therefore, a new multiprobe fluorescence in situ hybridization (FISH) method, using DNA probes for three targets (centromere and telomere of chromosome 1, centromere of chromosome 8), was developed to detect human sperm carrying three types of chromosomal defects: (1) terminal duplications or deletions in chromosome 1p, (2) aneuploidy involving chromosomes 1 or 8, and (3) diploidy. Baseline frequencies were determined for three healthy donors who had been previously evaluated for sperm cytogenetics by the human-sperm/hamster-oocyte cytogenetic technique (hamster technique). Among approximately 120,000 sperm analyzed by the new FISH method, the average baseline frequencies of sperm carrying telomeric duplications and deletions of 1p were 3.2 +/- 1.9 and 2.9 +/- 3.6 per 10(4), respectively. Diploid sperm was found in an average frequency of 6.6 +/- 4.0 per 10(4). Average frequencies of disomic sperm for chromosomes 1 or 8 were 1.7 +/- 2.2 and 1.9 +/- 2.3 per 10(4), respectively. Inter-individual differences were observed for deletions of 1p but not for the other sperm phenotypes. A good correlation was obtained between the frequencies of sperm with structural chromosome aberrations detected with the new assay and the frequency of sperm carrying premeiotic or meiotic cytogenetic damage detected with the hamster technique. The observed levels of numerical aberrations with the new FISH assay were within range of the baseline frequencies reported by the hamster technique. The newly developed FISH assay has promising applications in genetic, clinical, physiological and toxicological studies.

This complex is significant because it: (1) displays evidence of processes active in magma chambers which are crystallizing cumulus phases; (2) resembles many mid-Mesozoic plutons described in the western and central Sierra Nevada and western Mojave desert which may all be petrologically related; and (3) may be used as a diagnostic tectonic marker for Mesozoic tectonic reconstructions of the Mojave Desert and western Cordillera. The gabbroic body is unusual for its compact, near-circular plan, conspicuous banding and layering and reverse geochemical zonation. The mafic complex was intruded as a hydrous magma and was emplaced as a concentric epizonal pluton. Oxygen isotopic data indicate the melt was mantle derived but has been contaminated by assimilation of metasediments. The gabbro was likely generated by reaction of olivine with fractionated melt from the melting of a low MgO basalt under water-saturated conditions. The banding and layering is ascribed to the cyclic ascent of felsic rejected solute along the walls of the chamber and its accumulation near the roof of the complex. Cooling was facilitated by conduction and the presence of pendant rocks at uppermost levels. The Shadow Mountains gabbros resemble other gabbroic bodies of similar Jurassic age throughout the Sierra Nevada, Mojave Desert and Transverse Ranges, California (Lahren and Schweickert, 1994; Miller and Glazner, 1995). These intrusions are useful as markers of subsequent large-scale tectonic crustal displacements affecting the western Mojave Desert and Sierra Nevada. In particular, the Shadow Mountains gabbros show age, mineralogic and textural affinities with correlative gabbroic complexes in the central Sierra Nevada 400 km to the north. All these plutonic bodies may represent subvolcanic sources of the Jurassic-Cretaceous Independence dike swarm in the western Mojave Desert and eastern Sierra Nevada.

The abundance pattern of these four cosmogenic radionuclides and of noble gases indicates QUE 93069 and QUE 94269 were a paired fall and were exposed to cosmic rays near the surface of the Moon for at least several hundred million years before ejection. After the meteorite was launched from the Moon, where it had resided at a depth of 65-80 g/cm (super 2) , it experienced a short transition time, ca. 20-50 ka, before colliding with the Earth. The terrestrial age of the meteorite is 5-10 ka.

Our data support but considerably extend the earlier studies of Shen and Beer and their colleagues in the upper 0.75 Ma Luochuan loess-paleosol sequences. The effect of climatic change is dramatically expressed by (super 10) Be concentrations: (1) in the red-clay sediments, for which we estimate model accumulation rates of 5.8 and 8.7 m Ma (super -1) for the upper sequences in Lingtai and Baoji, respectively; (2) in the paleosols where soil maturation processes are manifest in the (super 10) Be distribution within different size fractions, accompanied by downward movement to zones of high authigenic mineral concentration; and (3) in loess samples which, at deposition, had an appreciable endowment of (super 10) Be from the dust source regions. On the basis of leaching experiments, we estimate that, on average, the paleosol layers lost about 3+ or -3 of their initial (super 10) Be content to the underlying layers by transport with water. Finally, we estimate that the relative average zonal precipitation rate during glacial periods was approximately (2/3)Xthe average interglacial value. The estimates of the initial (super 10) Be concentrations and dust composition are consistent with the measured values for the recent atmospheric dust falls sampled from the Loess Plateau and the Shandong Peninsula.

Neutron monitor data were used to normalize the measured concentrations in order to calculate production rates equivalent to the cosmic ray flux averaged over four solar cycles (43 years). The (super 7) Be production rates thus obtained correspond to 6.03 + or - 0.07 X 10 (super -6) atom g (super -1) .O s (super -1) at Echo Lake and 5.06 + or - 0.20 X 10 (super -6) atom g (super -1) .O s (super -1) at La Jolla. The (super 10) Be production rates correspond to 3.14 + or - 0.18 X 10 (super -6) atom g (super -6) .O s (super -1) at Echo Lake and 2.68 + or - 0.47 X 10 (super -7) atom g (super -1) .O s (super -1) at La Jolla. When compared with (super 10) Be production rates determined in (super 10) Be-saturated rocks from the Antarctic and with theoretical calculations based on meteorite and lunar sample data, we find that the million-year average production rate is about 14-177% greater than the present production rate averaged over the last four solar cycles. Comparison with production rates determined by measuring glacially polished rocks from the Sierra Nevada in California indicates that average production (based on a revised 13,000-year deglaciation age and a geographic latitude correction) is about 11% greater than the average over the last four solar cycles. The measured (super 10) Be/ (super 7) Be production ratio in oxygen is 0.52 + or - 0.03 at Echo Lake and 0.55 + or - 0.07 at La Jolla. Copyright 1996 by the American Geophysical Union.

Graphitization was complete by the lowest grade of metamorphism attained in the area ( approximately 450 degrees C and 450 MPa). In low-grade rocks, graphite occurs as inclusions within calcite and along grain boundaries, and in medium-grade rocks, it concentrates near porphyroblasts. In neither suite does graphite form interconnected networks. Average reduced carbon abundances are 4400 and 2800 ppm for the low- and medium-grade rocks, respectively. High-grade rocks are almost void of graphite, except for one specimen. The delta (super 13) C values were determined for graphite and carbonates and delta (super 18) O values were determined for the carbonates and silicate residues. There is no change in isotopic values between low- and medium-grade rocks. In contrast, high-grade rocks show marked decreases in delta (super 13) C and delta (super 18) O values of approximately 4 per mil compared to low- and medium-grade rocks. Both isotopic analyses and graphite depletion in high-grade rocks were caused by influx of large quantities of magmatic water during peak metamorphism. Electrical conductivity was measured in the laboratory on representative specimens. Rocks with high carbon content (>7000 ppm) from both the low- and high-grade zones display almost an order of magnitude higher electrical conductivity than expected from their fluid content alone. Graphite does not form an interconnected network in these rocks, yet it combines with the saline fluids to significantly increase electrical conductivities.

To what extent this asymmetry between the two ocean basins was maintained over the past 20 kyr is poorly known because there are few unambiguous proxy records of ventilation from the North Pacific. We present new data for two sediment cores from the California margin at 800 and 1600 m depth to argue that the depth of ventilation shifted repeatedly in the northeast Pacific over the course of deglaciation. The evidence includes benthic foraminiferal Cd/Ca, (super 18) O/ (super 16) O, and (super 13) C/ (super 12) C data as well as radiocarbon age differences between benthic and planktonic foraminifera. A number of features in the shallower of the two cores, including an interval of laminated sediments, are consistent with changes in ventilation over the past 20 kyr suggested by alternations between laminated and bioturbated sediments in the Santa Barbara Basin and the Gulf of California [Keigwin and Jones, 1990; Kennett and Ingram, 1995; Behl and Kennett, 1996]. Data from the deeper of the two California margin cores suggest that during times of reduced ventilation at 800 m, ventilation was enhanced at 1600 m depth, and vice versa. This pronounced depth dependence of ventilation needs to be taken into account when exploring potential teleconnections between the North Pacific and the North Atlantic.

These very high rates of sea level rise indicate periods of exceptionally rapid deglaciation of remaining ice sheets. The Laurentide Ice Sheet is commonly targeted as the source of the first, and largest, of the meltwater pulses (mwp-IA between approximately 14,200 (12,200 (super 14) C years B.P.) and 13,700 years ago (11,700 (super 14) C years B.P.)). In all oceanic records of deglaciation of the former northern hemisphere ice sheets that we review, only those from the Gulf of Mexico and the Bermuda Rise show evidence of low delta (super 18) O values at the time of mwp-IA, identifying the southern Laurentide Ice Sheet as a potential source for mwp-IA. We question this source for mwp-IA, however, because (1) ice sheet models suggest that this sector of the ice sheet contributed only a fraction (<10%) of the sea level needed for mwp-IA, (2) melting this sector of the ice sheet at the necessary rate to explain mwp-IA is physically implausible, and (3) ocean models predict a much stronger thermohaline response to the inferred freshwater pulse out of the Mississippi River into the North Atlantic than is recorded. This leaves the Antarctic Ice Sheet as the only other ice sheet capable of delivering enough sea level to explain mwp-IA, but there are currently no well-dated high-resolution records to document this hypothesis. These conclusions suggest that reconstructions of the Laurentide Ice Sheet in the ICE-4G model, which are constrained to match the sea level record, may be too low for time periods younger than 15,000 years ago. Furthermore, delta (super 18) O records from the Gulf of Mexico show variable fluxes of meltwater from the southern margin of the Laurentide Ice Sheet which can be traced to the opening and closing of eastward draining glacial-lake outlets associated with surging ice sheet behavior. These variable fluxes through eastern outlets were apparently sufficient to affect formation of North Atlantic Deep Water, thus underscoring the sensitivity of this process to changes in freshwater forcing.

Our method is based upon the statistical properties of the microgeometry as observed in scanning electron micrograph (SEM) images of cross sections of porous materials. This method uses a simple statistical measure of microstructure called the spatial correlation function. We formulate a two-point spatial correlation function and show how it can be used to estimate porosity, specific surface area, and other microstructural features such as pore and grain sizes. The porosity and specific surface area are of special interest as they can be used in a Kozeny-Carman relation to predict permeability of porous materials. We explore the Kozeny-Carman relation and show how it incorporates a characteristic microstructural length parameter similar to that used in other analyses of permeability. We analyze SEM images of several different porous glasses and natural sandstones using the two-point correlation function, discuss the importance of image resolution, and show for the sandstones studied here how the appropriate choices of image resolution can be made so the measured parameters are consistent with those used in a simple flow model for computation of permeability. Estimates of permeabilities for several different porous glasses and natural sandstones are presented. Comparison of these estimates to laboratory measurements shows good qualitative agreement and quantitative agreement within about a factor of 2 for most samples and 3 for all samples.

AN - 78355896; 8824508 AB - Understanding the significance of somatic mutations requires knowledge of the mutations that occur in vivo in healthy people. The molecular characterization of mutations in the hypoxanthine phosphoribosyltransferase (hprt) gene in 217 independent T-lymphocyte mutants from 172 donors, including smoking and non-smoking males and females, reveals a broad spectrum of in vivo somatic mutation occurring in a population of healthy people. Identification of the DNA alteration in individual mutant clones was accomplished using either one or a combination of multiplex polymerase chain reaction analysis of genomic DNA, sequencing of cDNA, and genomic DNA sequencing. The total spectrum consists of 59% (128/217) base substitutions: 126 simple and two tandem CC>TT base substitutions; 39% (85/217) deletion/insertion type mutations: 30 frameshifts, 26 small (3-200 basepairs) and 27 large deletions, and two duplications; and the remaining 2% (4/217) complex mutations involving the deletion of one to 11 basepairs which are replaced by 1 to 10 basepairs. No significant difference was detected between the base substitution spectra for the smokers and the non-smokers. Analysis of the number of mutations occurring at any one base position led to the identification of three hotspots for mutations at basepairs 197, 508 and 617, in the hprt gene coding region. Spontaneous deamination of CpG may be implicated in the creation of basepair 508 as a hotspot since all mutations detected are C>T transitions resulting in the nonsense mutation, TAG. At basepairs 197 and 617 both G>T transversions and G>A transitions were found indicating that at least two mechanisms were involved in creating mutations at these positions. Comparison of the mutation spectra from two populations can provide insight into the origin of the mutations. This study provides an excellent base for comparison of mutation spectra in other human populations.

AN - 78344224; 8800202 AB - Chromosome translocations are persistent indicators of prior exposure to ionizing radiation and the development of 'chromosome painting' to efficiently detect translocations has resulted in a powerful biological dosimetry tool for radiation dose reconstruction. However, the actual stability of the translocation frequency with time after exposure must be measured before it can be used reliably to obtain doses for individuals exposed years or decades previously. Human chromosome painting probes were used here to measure reciprocal translocation frequencies in cells from two tissues of 8 rhesus monkeys (Macaca mulatta) irradiated almost three decades previously. Six of the monkeys were exposed in 1965 to whole-body (fully penetrating) radiation and two were unexposed controls. The primates were irradiated as juveniles to single doses of 0.56, 1.13, 2.00, or 2.25 Gy. Blood lymphocytes (and skin fibroblasts from one individual) were obtained for cytogenetic analysis in 1993, near the end of the animals' lifespans. Results show identical dose-response relationships 28 y after exposure in vivo and immediately after exposure in vitro. Because chromosome aberrations are induced with identical frequencies in vivo and in vitro, these results demonstrate that the translocation frequencies induced in 1965 have not changed significantly during the almost three decades since exposure. Finally, our emerging biodosimetry data for individual radiation workers are now confirming the utility of reciprocal translocations measured by FISH in radiation dose reconstruction.

Proliferation in normal, injured and diseased tissue, growth factors, differentiation, DNA replication sites and in situ hybridization. AN - 78492632; 8894660 AB - This paper is a continuation of parts I (history, methods and cell kinetics) and II (clinical applications and carcinogenesis) published previously (Dolbeare, 1995 Histochem. J. 27, 339, 923). Incorporation of bromodeoxyuridine (BrdUrd) into DNA is used to measure proliferation in normal, diseased and injured tissue and to follow the effect of growth factors. Immunochemical detection of BrdUrd can be used to determine proliferative characteristics of differentiating tissues and to obtain birth dates for actual differentiation events. Studies are also described in which BrdUrd is used to follow the order of DNA replication in specific chromosomes, DNA replication sites in the nucleus and to monitor DNA repair. BrdUrd incorporation has been used as a tool for in situ hybridization experiments.

AN - 78479771; 8883473 AB - The primary food mutagens found in cooked meat are the heterocyclic aromatic amines, including 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx). High dose, acute exposures of MeIQx produce hepatic tumours in some mouse and rat strains. By assaying chromosome damage it may be possible to correlate aberrations with exposure to a mutagen. Whole chromosome painting by fluorescence in situ hybridization allows the rapid screening of metaphase chromosomes for rearrangements. This technique was applied to female mice (C57BL/6) chronically fed 100-400 ppms MeIQx for up to 6 months. Two tissues, blood and bone marrow, were screened with multicolour whole chromosome painting probes (1,2,3 and 8). The mice showed no outward signs of toxicity at any dose and very few chromosome aberrations were observed. A slight but significant increase in sister chromatid exchanges (SCE) was seen at 400 ppm in blood at 6 months. When MeIQx was removed from the diet for 1 month there was an apparent decline in SCEs only for animals previously given the 400 ppm diet.

In the experiment described, a simulated 1-kt nuclear explosion was produced in bedded tuffs of Rainier Mesa, Nevada, test site by detonating 1.3 million kg of chemical explosives. Analyses are presented of (super 3) He and SF (sub 6) (the latter to minimize thermal degradation of the (super 3) He tracer). Trace gases are transported to the surface within weeks to 1 yr along faults and fractures driven by barometric P variations. For a 1 kt nuclear test, short-lived (super 133) Xe and (super 37) Ar would, it is predicted, be detectable approximately 50 and 80 days respectively after the detonation.

A unique correlation emerges among the Na, Ca and Cl concentrations in many of these basinal fluids, attributed to a charge balance relation between Na and Ca suggesting a 2 to 1 exchange with plagioclase. Most formation fluids adhere to a linear regression with a slope of near-unity (the 'Basinal Fluid Line') on an excess-deficit plot and show that this linearity is independent of basin lithology. Dolomitization of calcite as a major source of the high Ca in these fluids is not established.

On surfaces, PDFs appear as narrow (50-500 nm) lamellae filled with amorphosed quartz (diaplectic glass) which can be etched with hydrofluoric acid or with hydrothermal alkaline solutions. In contrast, slow-strain-rate tectonic deformation pressure produces wider, semi-linear and widely spaced arrays of dislocation loops that are not glass filled. Etching samples with HF before examination in a scanning electron microscope (SEM) allows for unambiguous visual distinction between glass-filled PDFs and glass-free tectonic deformation arrays in quartz. This etching also reveals the internal "pillaring" often characteristic of shock-induced PDFs. This technique is useful for easily distinguishing between shock and tectonic deformation in quartz, but does not replace optical techniques for characterizing the shock features.

Carbon aerogel is an ideal electrode material because of its low electrical resistivity (<40 m(omega )-cm), high specific surface area (400 to 1100 m (super 2) /g), and controllable pore size distribution (<50 nm). This approach may avoid the generation of a substantial amount of secondary waste associated with ion exchange processing. Ion exchange resins require concentrated solutions of acid, base, or salt for regeneration, whereas carbon aerogel electrodes require only electrical discharge or reverse polarization. Aqueous solutions of NaCl, NaNO (sub 3) , NH (sub 4) ClO (sub 4) , Na (sub 2) CO (sub 3) , Na (sub 2) SO (sub 4) and Na (sub 3) PO (sub 4) have been separated into concentrate and high-purity product streams. The deionization of a 100 mu S/cm NaCl solution with two parallel stacks of carbon aerogel electrodes in a potential-swing mode is discussed in detail. The selective removal of Cu, Zn, Cd, Pb, Cr, Mn, Co and U from a variety of process solutions and natural waters has also been demonstrated. Feasibility tests indicate that the remediation of Cr(VI)-contaminated ground water may be possible.

The Thermodynamic Data Determinations task supplies data needed to resolve performance or design issues and the development of the data base will remain an iterative process as needs change or data improve. For example, data are needed to predict: (1) major ion groundwater chemistry and its evolution, (2) mineral stabilities and evolution, (3) engineered barrier near-field transport and retardation properties, (4) changes in geochemical conditions and processes, (5) solubilities, speciation and transport of waste radionuclides and (6) the dissolution of corrosion of construction and canister materials and the effect on groundwater chemistry and radionuclide solubilities and transport. The system is complex and interactive, and data need to be supplied in order to model the changes and their effect on other components of the system, e.g., temperature, pH and redox conditions (Eh). Through sensitivity and uncertainty analyses, the critical data and system parameters will be identified and the acceptable variations in them documented.

AN - 78167040; 8676907 AB - Efficient molecular methods are being developed for detecting various types of cytogenetic genetic damage in sperm, especially numerical aneuploidy for chromosomes involved in trisomies that survive at birth. These methods provide new approaches for identifying potentially detrimental environmental exposures, genetic predisposition, chromosomal rearrangements, and physiologic factors which may increase a man's risk of fathering a genetically defective offspring. Corollary methods are also being developed for detecting sperm aneuploidy in laboratory rodents and these will be used to make inter-species comparisons of mutagen sensitivities and for investigating mechanisms of induction and persistence of aneuploidy. Validated assays for detecting genetic alterations in human and rodent sperm (of which sperm aneuploidy is a first example) permit comparisons of somatic and germinal response to mutagens within individuals, comparisons of human and rodent germinal sensitivity to mutagens, and can be applied in an extended parallelogram model to sperm for assessing heritable risk resulting from paternal mutagen exposures.

It is well recognized that seismological discriminants based on P/S ratios or individual phase spectral ratios must be corrected for regionally dependent path effects for successful discrimination to be achieved. Such corrections usually involve only distance-dependent decay, parameterized to account for geometric spreading and attenuation factors averaged over some geographic region. However, large scatter persists in distance-corrected discriminants, which degrades their performance, and strategies are needed to further reduce the scatter by accounting for individual path variability. We demonstrate that characterizing some of the path variability by the readily measured surface topographic roughness along each path allows reduction of the scatter in some regional discriminants. P (sub g) /L (sub g) and P (sub n) /L (sub g) ratios and P (sub g) , P (sub n) and L (sub g) low-frequency/high-frequency spectral ratios for 80 earthquakes in the Western United States recorded at four stations of the Livermore NTS Network are analyzed for path effects. While all of these discriminants display distance dependence, log P (sub g) /L (sub g) is also found to be significantly correlated with average surface roughness along each path. The correlation is emphasized when the product of distance and roughness is used as an independent variable, and the data in the frequency range 1 to 6 Hz have the strongest trends. Corrections based on the correlations with distance and roughness can reduce the variance of the log P (sub g) /L (sub g) discriminant by 22 to 25% in the 2- to 4-Hz band. Log P (sub n) /L (sub g) and individual phase spectral ratios have stronger distance dependence than log P (sub g) /L (sub g) , but the correlation with surface roughness is weak for those measurements. It appears that interchange of P (sub g) and L (sub g) energy that reverberates in the crust accounts for the sensitivity to the gross wave-guide properties that are manifested in the surface roughness parameterization. The results support the concept of pursuing path corrections beyond purely range-dependent trends.

Fluid mixing simulations were designed to assess the role that cation exchange plays in controlling the composition of fluids entering the HRL via fracture flow. Because the predominant clay mineral observed in fractures in the Redox Zone has been identified as illite or mixed layer illite smectite, an exchanger with the properties of illite was used to simulate cation exchange. Cation exchange on illite was modeled using three exchange sites, a planar or basal plane site with properties similar to smectite, and two edge sites that have very high affinities for K, Rb, and Cs. The results of the geochemical modeling suggest that Na, Ca, and Sr concentrations in the fluid phase may be controlled by cation exchange reactions that occur during mixing, but that Mg appears to behave conservatively.

Conservative mixing models do not adequately account for changes in Na, Ca and Mg concentrations during mixing. Mixing between relatively dilute shallow waters and more concentrated waters at depth along fracture zones was modeled using the EQ3/6 geochemical modeling package. A cation exchange model was added to the code to describe simultaneously aqueous speciation, mineral precipitation/dissolution, and equilibration between a fluid and a cation exchanger. Fluid chemistries predicted to result from mixing were compared with those monitored from boreholes intersecting the fracture zone. Modeling results suggest that less than 0.1 equivalent of a smectite exchanger per liter of groundwater is necessary to account for discrepancies between predictions from a conservative mixing model and measured Na and Ca concentrations. This quantity of exchanger equates to an effective fracture coating thickness of 20 mu or less given a fracture aperture width of 1,000 mu or less. Trends in cation ratios in the fluid cannot be used to predict trends in cation ratios on the exchanger because of the influence of ionic strength on heterovalent exchange equilibrium. It is expected that Na for Ca exchange will dominate when shallow waters such as HBHO2 are mixed with deeper waters. In contrast, Na for Mg exchange will dominate mixing between deeper waters.

The mutagenic potency of PhIP is highly dependent upon cytochrome P450 N-hydroxylation. In the present study, the ability of rat colon tissue to activate PhIP to a mutagen was investigated in Salmonella typhimurium (strains TA98 and YG1024) and rat colon tissue slices. In the Ames/Salmonella assay, using rat colon S9 as the activating system, no mutations were evident from bacteria exposed to PhIP at any concentration tested. However, mutations were observed when bacteria were exposed to 2-aminoanthracene (2AA) and colon S9, indicating sufficient P450 activity in the S9 to activate 2AA but not PhIP. In rat colon slice preparations, the sulfotransferase and acetyltransferase inhibitors pentachlorophenol (PCP) and 2,6-dichloro-4-nitrophenol (DCNP) were used to modulate DNA adduct and metabolite formation. Incubations of 3-methylcholanthrene-induced colon slices dosed with 50 mu M [ super(3)H]PhIP produced no detectable metabolites. However, incubations of uninduced slices exposed to 10 mu M of the reactive intermediate, [ super(3)H]2-(hydroxyamino)-1-methyl 6-phenylimidazo[4,5-b]pyridine (N-hydroxy-PhIP), produced a single detectable metabolite, a glucuronide conjugate of N-hydroxy-PhIP. This metabolite decreased when PCP or DCNP was added to the incubation medium. DNA adducts were detected in colon slices exposed to N-hydroxy-PhIP at approximately 33 adducts/10 super(7) nucleotides. Interestingly, when PCP was added to the incubation mixture, an increase in DNA adduct levels was detected, whereas DCNP produced a decrease in adducts. Because these inhibitors are thought to have similar mechanisms with regard to sulfotransferase inhibition, the inverse relationship in DNA adduct levels due to PCP or DCNP treatment is at present unexplainable. The formation of DNA adducts and metabolites from colon slices exposed to N-hydroxy-PhIP but not PhIP implies that there is insufficient P450 activity in the rat colon to activate PhIP to hydroxylated metabolites, suggesting that the rat colon is a site of Phase II metabolism for PhIP and that the liver is the primary source for hydroxylation.

AN - 78283662; 8781370 AB - Fluorescence in situ hybridization with chromosome-specific composite DNA probes (chromosome painting) is a reliable and efficient method for detecting structural chromosome aberrations. Painting is now being used to quantify chromosome damage in many human populations. In one such study we evaluated 91 unexposed people ranging in age from birth (cord bloods) to 79. We established a baseline frequency of stable aberrations that showed a highly significant curvilinear increase with age (p < 0.00001) that accounted for 70% of the variance among donors. The magnitude of this effect illustrates the importance of understanding the cytogenetic changes that occur with age, which is particularly important for quantifying the effects of prior adverse environmental, occupational, or accidental exposure. In this paper we use the data obtained in our previous study to characterize the distribution of stable aberrations by age and pack-years of cigarette smoking. We also provide estimates of the number of cell equivalents that need to be scored to detect a given increase in aberrations above the background level surveyed in this population.

AN - 77989417; 8690586 AB - The future use of land contaminated with radionuclides depends upon scientifically defensible bases for setting limits for radionuclides in soil. The purpose of this work is to develop such bases for establishing "posting criteria" to protect nonradiological workers at the Nevada Test Site and to provide a rationale for cost-effective measurements to readily determine the boundary conditions. The analysis begins with a mandated limit on total effective dose equivalent (1 mSv y(-1)) via all pathways. The possible pathways of exposure are external gamma exposure, inhalation of resuspended material, and incidental soil ingestion. These pathways are evaluated for each radionuclide of interest on the Nevada Test Site, and the results are used to define for each radionuclide the deposition-density limits for each pathway of exposure. The minimum deposition-density limits are noted to occur via the external gamma-exposure pathway for most radionuclides; exceptions are incidental soil ingestion for 90Sr/90Y and inhalation for 238Pu, 239,240Pu, and 241Am. The limiting values of deposition density or average concentration in soil are then determined appropriately by combining all pathways. Procedures are developed for dealing with mixtures of many radionuclides and to apply the principles developed so that even a simple measurement of external gamma-exposure rate may be used to define the boundary conditions in the field, provided that the relative abundance of the radionuclide mixture is known and that the defining level of exposure rate is sufficiently above background.

Waveforms of deep regional events in the downgoing Nazca slab and teleseismic earthquakes were processed to isolate the P-to-S converted phases from the Moho in order to compute the crustal thickness. We found crustal-thickness variations of nearly 40 km across the Andes. Maximum crustal thicknesses of 70 - 74 km under the Western Cordillera and the Eastern Cordillera thin to 32 - 38 km 200 km east of the Andes in the Chaco Plain. The central Altiplano at 20 degrees S has crustal thicknesses of 60 to 65 km. The crust also appears to thicken from north (16 degrees S, 55 - 60 km) to south (20 degrees S, 70 - 74 km) along the Eastern Cordillera. The Subandean zone crust has intermediate thicknesses of 43 to 47 km. Crustal-thickness predictions for the Andes based on Airy-type isostatic behavior show remarkable overall correlation with observed crustal thickness in the regions of high elevation. In contrast, at the boundary between the Eastern Cordillera and the Subandean zone and in the Chaco Plain, the crust is thinner than predicted, suggesting that the crust in these regions is supported in part by the flexural rigidity of a strong lithosphere. With additional constraints, we conclude that the observation of Airy-type isostasy is consistent with thickening associated with compressional shortening of a weak lithosphere squeezed between the stronger lithosphere of the subducting Nazca plate and the cratonic lithosphere of the Brazilian craton.

Stable isotope (delta (super 18) O, delta D, delta (super 13) C) and (super 14) C measurements of surface and groundwater samples were used to identify recharge areas, and to evaluate aquifer residence times and flow paths. Recharge locations were constrained from the regional decrement in meteoric water delta (super 18) O values as a function of elevation, determined to be -0.23 per mil per 100 m for small springs and creek waters collected along the western Cascade slope of this region. In general, the large-volume springs are lower in delta (super 18) O than surrounding meteoric waters, and are inferred to originate in high-elevation, high-precipitation regions up to 50 km away from their discharge points. Large spring (super 14) C abundances range from 99 to 41% modern carbon (pmc), and most show evidence of interaction with three distinct carbon isotope reservoirs. These reservoirs are tentatively identified as (1) soil CO (sub 2) gas equilibrated under open system conditions with groundwater in the recharge zone [delta (super 13) C (sub DIC) nearly equal -18 per mil, (super 14) C> or =100 pmc (2) dissolved carbon equilibrated with atmospheric CO (sub 2) gas [delta (super 13) C (sub DIC) nearly equal +1 per mil, (super 14) C> or =100 pmc], and (3) dissolved carbon derived from volcanic CO (sub 2) gas emissions [delta (super 13) C (sub DIC) nearly equal 0 per mil, (super 14) C = 0 pmc]. Many regional waters show a decrease in (super 14) C abundance with increasing delta (super 13) C values, a pattern indicative of interaction with dead carbon originating from volcanic CO (sub 2) gas. Several lines of evidence suggest that actual groundwater residence times are too short (< or =200 years) to apply radiocarbon dating corrections. In particular, water temperatures measured at springs show that deep groundwater circulation does not occur, which implies an insufficient aquifer volume to account for both the high discharge rates and long residence times suggested by (super 14) C apparent ages. The large springs also exhibit rapid decreases in flow during periods of drought that suggests a high level of aquifer interconnectivity to the recharge area. The estimated amount of volcanic CO (sub 2) dissolved in surface and groundwater originating from the Lassen highlands is consistent with the conversion of approximately 10% of the geothermal CO (sub 2) flux into dissolved inorganic carbon.

The study also uses data from the volcanic rocks to identify deep crustal xenoliths that are samples of new crust created by the Tertiary magmatism. The isotopic composition of the mantle component is defined by mantle-derived pyroxenites that are interpreted to have precipitated from mid-Cainozoic basaltic magmas. This component has epsilon (sub Nd) approximately +1.5, (super 87) Sr/ (super 86) Sr approximately 0.7043 and (super 206) Pb/ (super 204) Pb approximately 18.6. Within the upper ignimbrite and associated anadesitic and dacitic lavas, initial (super 87) Sr/ (super 86) Sr is positively correlated with SiO (sub 2) , reaching 0.7164 in the ignimbrite. Initial (super 206) Pb/ (super 204) Pb ratios also show a positive correlation with silica, whereas epsilon V>Nd values have a crude negative correlation, reaching values as low as -2. Of the four isotopically distinct crustal components identified from studies of granulite xenoliths, only the sedimentary protolith of the paragneiss xenoliths can be responsible for the high initial (super 87) Sr/ (super 86) Sr of the upper ignimbrite. The Nd, Sr, and Pb isotopic compositions of the upper ignimbrite can be modelled with relatively modest assimilation (up to 20%) of the sedimentary component with or without Proterozoic granulite. Gabbroic composition granulite xenoliths have distinctive Nd, Sr and Pb isotope ratios that cluster closely within the range of compositions found in the andesitic and dacitic lavas. These mafic granulites are cumulates, and their protoliths are interpreted to have precipitated from the intermediate to silicic magmas at 32-31 m.y. These mafic cumulate rocks are probably representative of much of the deep crust that formed during mid-Cainozoic magmatism in Mexico.

The goal was to test the applicability of isotope techniques for determining the current groundwater flow paths and flow rates in the OCWD spreading facilities. Successful results could then be used to predict the fate of proposed reclaimed waste water recharge. Stable isotope measurements in surface waters and groundwaters in the Forebay region of the Orange County groundwater basin provided a general source indicator. The data defined three general groups: (1) groundwater derived from recharged Santa Ana River water (SAR),(2) groundwater resulting from a mixture of recharged Colorado River water and the SAR, and (3) groundwater recharged from the Santiago basin area.

We modeled the associated broadband waveforms of two earthquakes to estimate an average crustal structure for the Altiplano. The resulting model is characterized by an anomalously low mean P velocity of 6.0 km/s, a low Poisson's ratio of 0.25, and a crustal thickness of 65 km. The combination of the low mean velocity and low Poisson's ratio can be explained only by a predominantly quartz-rich, felsic bulk composition. This constraint precludes significant volumes of magmatic addition from the mantle contributing to the great thickness of the Altiplano crust, but is consistent with thickening by compressive shortening concentrated in a weak felsic layer.

We use the method to compute path- and site-corrected seismic momentrate spectra for 117 recent western United States earthquakes. Empirical Green's function corrections were applied to our surface- and body-wave coda envelope measurements to generate S-wave source spectra. These source spectra provide stable, single-station estimates of radiated seismic energy E (sub s) and seismic moment M (sub o) that for common events are in excellent agreement with network-averaged estimates obtained using local and regional data. Teleseismic moment estimates are compatible with our regional results, but teleseismic energy estimates appear to be nearly an order of magnitude low. We estimated the seismic moment of events ranging between M (sub w) 2.2 and 7.3, and energy estimates for which we had measured at least 70% of the total energy, generally events above M (sub w) 3.3. We use these estimates to examine the behavior of derived parameters such as the Orowan stress drop (Delta sigma = 2mu E (sub s) /M (sub o) ). While the earthquakes we studied have a small range in Orowan stress drop, generally between 0.1 and 20 MPa, they show a strong tendency for Orowan stress drop to increase with moment, approximately as M (sub o) (super 0.25) . We believe this is a source effect and is not due to inadequate bandwidth or attenuation correction, and note that this trend appears to continue for microearthquakes as described in a recent deep borehole study in southern California. Many of the large high stress drop earthquakes show complexity in their momentrate spectra near the corner frequency and cannot be fit by a simple omega -square model. Instead, above the first corner frequency, the spectral decay ranges between f (super -1.0) and f (super -1.5) . This leads to larger estimates of radiated energy than predicted with a simple omega -square model and has implications for seismic hazard estimation. Coda envelopes have three main advantages over direct arrivals for estimating seismic moment and energy: (1) Coda amplitudes vary little with geology and source-radiation anisotropy and allow accurate single-station applications; (2) path-corrected coda amplitude measurements can be applied to very large regions, allowing a comparison of source parameters throughout the western United States using a common methodology and stations; (3) because long-period coda can last for hours for large local and regional events, it allows the analysis of seismograms with clipped early arrivals.

AN - 78594437; 8998575 AB - An improved HPLC-based 32P-postlabeling assay has been developed for the analysis of DNA modified with the food carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). Postlabeled samples are loaded onto a C18 precolumn and adducted bases are retained while excess radioactivity and unmodified DNA bases are eluted directly to waste through a switching valve. The use of this HPLC in-line precolumn purification (HIPP) technique allows entire postlabeled samples to be analyzed without prior removal of inorganic phosphate and unmodified DNA bases. The method has a sample to sample precision of 15% and accuracy of 20%, at adduct levels of 2 adducts/10(7) bases and shows a linear relationship between signal and adduction levels from 1 adduct per 10(4) to approximately 2 +/- 1 adducts per 10(9) bases. Individual postlabeled DNA samples can be analyzed by HPLC in less than 1 h, allowing high throughput. The use of calf-thymus DNA (CT-DNA), highly modified with PhIP, or DNA isolated from mice chronically fed a PhIP-modified diet shows two major PhIP-DNA adduct peaks and three additional minor adduct peaks when labeled under ATP-limiting conditions. Isolation of the HPLC purified peaks and analysis by thin layer chromatography (TLC) matches the five HPLC peaks to the spots typically seen by TLC, including N-(deoxyguanosin-8-yl)-2-amino-1-methyl-6-phenylimidazo[4,5- b]pyridine (dG-C8-PhIP). Variations in digestion techniques indicate a potential resistance of the PhIP-DNA adducts to the standard enzymatic digestion methods. Attempts at adduct intensification by solid phase extraction, nuclease P1 enrichment or 1-butanol extraction decreased PhIP-DNA adduct peaks and introduced a large early eluting peak. Removal of the 3'-phosphate with nuclease P1 following the kinase labeling reaction simplifies the HPLC profile to one major peak (dG-C8-PhIP monophosphate) with several minor peaks. In addition to the high resolution provided by HPLC separation of the PhIP-DNA adducts, this method can be adjusted for analysis of other DNA adducts and is readily automated for high throughput.

AN - 78023133; 8638040 AB - The past several years has seen an increased awareness of the need to conduct ecological risk assessments (ERAs) for hazardous waste sites. One technique used in ERAs involves estimating contaminant exposure to individual animals of selected species, which is then compared to a reference dose derived from the literature. Exposure estimates are conducted on those species which are representative of the different trophic levels found at the site. In many terrestrial systems, fossorial (burrowing) vertebrates are found in both lower and upper trophic levels. As part of the ERA conducted for Site 300, Lawrence Livermore National Laboratory's high-explosive test facility, contaminant exposures were estimated for fossorial and nonfossorial vertebrates spanning two trophic levels. The results of the evaluation revealed that a significant pathway by which fossorial vertebrates could be exposed to trichloroethylene in soil was through the inhalation of contaminated subsurface burrow air. This was the first time that the importance of this ecological exposure pathway has been recognized. The results of this analysis suggest that further research into the ecological significance of subsurface burrow air contaminated with volatile organic compounds is warranted.

The crust thickens from southeast to northwest along the axis of the Sierra Nevada from 27 km in the Mojave Desert to 43 km near Fresno, California. A crustal welt is present beneath the Sierra Nevada, but the deepest Moho is found under the western slopes, not beneath the highest topography. A density model directly derived from the crustal velocity model but with constant mantle density satisfies the pronounced negative Bouguer anomaly associated with the Sierra Nevada, but shows large discrepancies of >50 mgal in the Great Valley and in the Basin and Range province. Matching the observed gravity with anomalies in the crust alone is not possible with geologically reasonable densities; we require a contribution from the upper mantle, either by lateral density variations or by a thinning of the lithosphere under the Sierra Nevada and the Basin and Range province. Such a model is consistent with the interpretation that the uplift of the present Sierra Nevada is caused and dynamically supported by asthenospheric upwelling or lithospheric thinning under the Basin and Range province and eastern Sierra Nevada.

The first type occurs in the Sacramento metropolitan area, where meteoric runoff is unnaturally high and 40 years of pumping have depressed water levels to 25 m below sea-level, inducing recharge from losing reaches of the Sacramento and American rivers. Lateral migration rates are quantified by the binary mixing between river water (delta (super 18) O = -10.8) and natural groundwater (delta (super 18) O = -7.0). The second type of mining occurs in agricultural regions to the west, where (super 14) C ages indicate that irrigation waters constitute more than 80% of modern recharge. This recharge has several characteristics of evaporated irrigation water, including: (1) high delta (super 18) O values (to >-6.0) that define closed contour patterns; (2) elevated NO (sub 3) concentrations (to 100 ppm); (3) low (super 14) C ages of less than 500 years. Stable isotope contours, augmented by (super 14) C data, provide dynamic recharge patterns in this profoundly disturbed, giant alluvial aquifer. On a large scale (>100 km (super 2) ), the lateral permeabilities of alluvial aquifers are essentially isotropic, whereas on a smaller scale (<25 km (super 2) ), anisotropy is evident and isotope values can be geographically complex and seasonally transient. Groundwater flow patterns implied by the isotope data can differ substantially from steady-state models based on head measurements.

We analyze over 1200 seismograms for Lg propagation from 185 local and regional earthquakes recorded at distances from 150 to 2000 km, 52 of which are located within the Tibetan Plateau, Although the propagation of Lg has been observed across most of Asia, Lg has not been observed for paths crossing the Tibetan Plateau. We analyze paths that cross the plateau boundaries. and paths contained entirely within the Tibetan Plateau. Lg is generated within the Tibetan Plateau and can propagate to epicentral distances of at least 600 km. For events located outside of the Tibetan Plateau, Lg is either absent or severely diminished for paths that cross both the Himalayan and Kunlun ranges, confirming that the margins of the plateau weaken Lg transmission. Based on the observations from our qualitative analysis, we invert Lg amplitudes for event/station paths that are confined to the Tibetan Plateau to estimate, the quality factor, Q. The inversion yields a frequency-dependent Q function: Q(f) = (366 + or - 37)f (super (0.45+ or -0.06)) (0.5 < or =f< or =16 Hz)z). Similar observations in other areas indicate that frequency-dependent apparent Q within the Tibetan Plateau is well below that expected for a typical continental interior. Instead, it has a frequency dependence that is characteristic of a tectonically active region.

We present evidence, based on the carbon isotopic composition of marine organic matter, that atmospheric CO (sub 2) levels at this time were on average only about 35% higher than the preindustrial value of 280 ppm. We also present carbon isotopic evidence for stronger thermohaline circulation in the Atlantic Ocean during the warmest intervals and propose that the North Atlantic "conveyor belt" may act as a positive feedback to global warming by enhancing sea ice retreat and decreasing high latitude albedo. Based on our results, it seems unlikely that the mid Pliocene warm period was a doubled CO (sub 2) world.

We analyzed the possible ground motion resulting from a M = 7.25 earthquake that ruptures 82 km of the Hayward fault for a site 1.4 km from the fault in the eastern San Francisco Bay area. We developed a suite of 100 rupture scenarios for the Hayward fault earthquake and computed the corresponding strong ground motion time histories. We synthesized strong ground motion with physics-based solutions of earthquake rupture and applied physical bounds on rupture parameters. By having a suite of rupture scenarios of hazardous earthquakes for a fixed magnitude and identifying the hazard to the site from the statistical distribution of engineering parameters, we introduce a probabilistic component into the deterministic hazard calculation.

Standard experimental techniques can be used because the physical conditions under which most solar system ices exist are within reach of conventional rock mechanics testing machines, adapted to the low subsolidus temperatures of the materials in question. The purpose of this review is to summarize the results of a decade-long experimental deformation program and to provide some background in deformation physics in order to lend some appreciation to the application of these measurements to the planetary setting.

At Hill Air Force Base in Utah, a free-product DNAPL plume (consisting predominantly of TCE) is pooled in water-wet soil on a thick clay aquitard. Groundwater pumping at Operable Unit 2 (OU 2) began in 1994; to date, nearly 30,000 gallons of DNAPL have been recovered from the site. From September, 1994 through September, 1995, changes in the basin during DNAPL pumping were monitored using an integrated geophysical system. Fiber optic sensors and neutron logs verify the presence of DNAPL in the vicinity of three boreholes which form a cross section from the perimeter of the basin to its center. Cross borehole electrical resistance tomography (ERT) images the changes in formation electrical properties due to the removal of DNAPL, extending the understanding of DNAPL removal between the boreholes. During pumping, electrical resistivities decreased; we suggest that these decreases are directly caused by the reduction in DNAPL. During ground water pumping, water with relatively low resistivity replaces some of the DNAPL pockets as the highly insulating DNAPL is removed. The results suggest that, as DNAPL is pumped from a nearby well, product slowly drains along the top of an aquitard and into the pump well, where it collects.

Several studies have been concluded to test the capabilities and limitations of ERT for two different applications. First, field experiments have been conducted to determine the utility of ERT to detect and map leaks from underground storage tanks during waste removal processes. Second, the use of ERT for long term vadose zone monitoring has been tested under different field conditions of depth, installation design, acquisition mode/equipment and infiltration chemistry. This work involves transferring the technology from Lawrence Livermore National Laboratory (LLNL) to the Resource Conservation and Recovery Act (RCRA) program at the DOE Hanford Site. This paper covers field training studies relevant to the second application for long term vadose zone monitoring. Electrical resistivity tomography is a cross-borehole, imaging technique for mapping subsurface resistivity variations. Electrodes are placed at predetermined depths in an array of boreholes. Electrical current is introduced into one electrode pair located in one borehole while the resulting voltage change is detected between electrode pairs in other boreholes similar to a surface dipole-dipole array. These data are tomographically inverted to image temporal resistivity contrasts associated with an infiltration event. Thus a dynamic plume is spatially mapped as a function of time. As a long-term vadose zone monitoring method, different field conditions and performance requirements exist than those for short term tank leak detection. To test ERT under these conditions, two vertical electrode arrays were constructed to a depth of 160 feet with a linear surface array between boreholes. The fielding was used to facilitate the technology transfer from LLNL to the Hanford RCRA program. Installation methods, commercial equipment and acquisition mode were evaluated to determine economic and technical feasibility to assist design of long-term monitoring networks. Preliminary results of the training test are presented. Until recently, vadose zone monitoring techniques could provide only local point or linear coverage for leak detection and thus, are used primarily under liquid collection systems at land disposal units. As developed by LLNL, ERT can provide areal coverage under waste treatment and storage facilities given the right conditions. Advantages of ERT to groundwater protection programs are explored along with suggestions for future uses where ERT can be employed today.

This paper provides a summary of the field experiments performed under a 15 m diameter steel tank mockup located at the Hanford Reservation, Washington. Two different leak events were created. About 3800 liters of saline solution were first released along a portion of the tank's edge and another 1900 liters were later released near the tank's center. The release rate averaged about 26 liters/hour for the leak on the tank's side and about 3.0 liters/hour for the center leak. Two and three dimensional tomographs were calculated using data collected before, during and after each spill. The tomographs show that, as the solution penetrated the soil, readily detectable resistivity decreases appeared where the associated plume was expected. The results indicate that the plume associated with these releases could be reliably detected after approximately 190 liters were released. Results are also shown where the metal tank is used as a large electrode.

One hundred ninety liters of PCE were released at a rate of 2 liters per hour from a point 0.5 m below ground surface. The spill was conducted within a double walled tank where saturated layers of sand, bentonite and a sand/bentonite mixture were installed. Complex electrical resistance measurements were performed from 4 vertical electrode arrays, each with 10 electrodes space between 3 m and 0.5 m depth. Data were taken before the release, several times during, and then after the PCE was released. Magnitude and phase were measured at 1 and 64 Hz. Data from before the release were compared with those during the release for the purpose of imaging the changes in conductivity resulting from the plume. Conductivity difference tomographs showed a decrease in electrical conductivity as the DNAPL penetrated the soil. A pancake-shaped anomaly developed on the top of a bentonite layer at 2 m depth. The anomaly grew in magnitude and extent during the release and borehole television surveys data confirmed the anomaly to be free-product PCE whose downward migration was stopped by the low permeability clay. The tomographs clearly delineated the plume as a resistive anomaly. Images showing phase changes caused by the spill are also presented. The phase changes at 64 Hz suggest that the DNAPL spill increased the induced polarization (IP) effect of the clay layers.

The study seeks to identify the more important impacts of medium heterogeneity, as embodied in spatially variable physical and chemical properties, on the migration and dilution rates of a model cocontaminant mixture, as well as on the overall partitioning among the aqueous and solid species formed from complexation and sorption reactions. Solid phase reactions are considered to occur on hydrous-ferric oxide (goethite) coatings on the sand and are controlled by the abundance of the oxide as a function of the specific sand surface area and larger-scale patterns of oxide deposition. The simulations involve calculation of fluid flow and chemical migration within highly resolved, two- and three-dimensional regions with synthetic material properties that approximate observed conditions in a sandy coastal aquifer. Model simulations in this system indicate that (1) the impact of correlation between reactive surface area and hydraulic conductivity, although evident, seems much less significant than the overall abundance and distribution of the reactive area, such as the kind of banded goethite patterns observed in a coastal sand body; (2) strong multicomponent interactions clearly reinforce the need to treat the mixture as a coupled system, as opposed to a series of independently reactive compounds; (3) simplifications can be made in extremely dilute problems that allow retardation effects to become concentration independent; and (4) for nonlinear reaction problems, three-dimensional models will be more appropriate than two-dimensional models to the extent that dispersion in the added dimension accelerates chemical dilution rates.

A priority is to better characterize the complex near-field environment in order to assess and predict the movement of radionuclides in groundwater. Other participating organizations include the Los Alamos National Laboratory (LANL), the U.S. Geological Survey (USGS) and the Desert Research Institute (DRI) of the University of Nevada. A radiologic source term in excess of 10 (super 8) curies of tritium, fission products, activation products and actinides is residual from more than three decades of underground nuclear weapons testing at the Nevada Test Site (NTS). Burial depths to insure containment of these explosions necessitated firing approximately one third of the more than 800 underground nuclear tests within one cavity radius or below the static water table. Work at LLNL has focused on studies of radionuclide transport under saturated, partially saturated or unsaturated conditions as well as investigations of the stable, radiogenic and cosmogenic isotope systematics of NTS groundwaters. LLNL has prioritized these studies because of the significance for potential radionuclide migration at the Nevada Test Site. LLNL utilizes expertise in nuclear weapons testing, radiochemical diagnostics, nuclear test phenomenology, mass spectrometry, aqueous geochemistry and field and laboratory studies of radionuclide migration to bring a unique measurement and interpretative capability to this research.

In one table we present the number of vegetation samples collected in the 1978 NMIRS and from 1986 through 1989. Again the majority of the (super 137) Cs data is from the 1986-1989 trips. We have not made additional analyses of (super 239+240) Pu, (super 241) Am and (super 90) Sr because the concentrations are very low and these radionuclides contribute less than 5% of an already very small dose. In another table we show the number of soil samples collected at each island in 1978 and the number collected since 1986. Most of the data are from 1986 through 1989. The major exception is (super 90) Sr where all of the data are from the 1978 NMIRS. We have done some additional Pu analyses of surface soils (0-5 cm depth) in the northern islands. A significant amount of new data for (super 137) Cs and (super 241) Am have been generated from the samples collected from 1986 through 1989. The data are presented in the form of summary tables, graphics, detailed appendices and aerial photographs of the islands with the sample locations marked. The identified sample locations from the 1978 NMIRS will be added later.

MRI procedures revealed sediment heterogeneities and preferential flow pathways inherent in the sediments as well as those created in the packing of the column. Sequential MRI images were also used to estimate tracer flow velocities and to detect density flows driven by density differences of as little as 0.0013 g/ml. Interpretation of the images emphasized the importance of small changes in hydraulic conductivity and of column orientation in experiments with fluids of different densities. MRI analysis during column flow experiments holds promise as a measurement technique to estimate retardation factors for selected solutes.

Like the Greenland records, the new Antarctic data exhibit a strong periodicity which follows expected changes in the production rate of (super 10) Be over the 11-year solar cycle. Noting that the amplitude of production-rate variation is both latitude and altitude dependent, we estimate the relative contribution of (super 10) Be from different atmospheric reservoirs. The calculations yield a relatively small (<35 %) contribution from the low-to-mid latitude stratosphere, suggesting a weak coupling between Antarctic (super 10) Be and geomagnetic field intensity.

However, in cases where sharp interfaces separate materials with contrasting hydraulic properties, these quantities may be discontinuous. Normally, velocities are interpolated to arbitrary particle locations when finite difference or finite element methods are used to solve the flow equation. The use of interpolation schemes that preserve discontinuities in velocity at material contacts can result in a random-walk model that does not locally conserve mass unless a correction is applied at these contacts. Test simulations of random-walk particle tracking with and without special treatment of material contacts demonstrate the problem. Techniques for resolving the problem, including interpolation schemes and a reflection principle, are reviewed and tested. Results from simulations of transport in porous media with discontinuities in the dispersion tensor show which methods satisfy continuity. Simulations of transport in two-dimensional heterogeneous porous media demonstrate the potentially significant effect of using a nonconservative model to compute spatial moments and breakthrough of a solute plume.

The method is a straightforward extension to three dimensions of the approach originally developed to study the diffraction of SH waves [Bouchon, 1985] and P-SV waves [Gaffet and Bouchon, 1989] by two-dimensipnal topographies. It relies on a boundary integral equation scheme formulated in the frequency domain where the Green functions are evaluated by the discrete wavenumber method. The principle of the method is simple. The diffracted wave field is represented as the integral over the topographic surface of an unknown source density function times the medium Green functions. The Green functions are expressed as integrals over the horizontal wavenumbers. The introduction of a spatial periodicity of the topography combined with the discretization of the surface at equal intervals results in a discretization of the wavenumber integrals and in a periodicity in the horizontal wavenumber space. As a result, the Green functions are expressed as finite sums of analytical terms. The writing of the boundary conditions of free stress at the surface yields a linear system of equations where the unknowns are the source density functions representing the diffracted wave field. Finally, this system is solved iteratively using the conjugate gradient approach. We use this method to investigate the effect of a hill on the ground motion produced during an earthquake. The hill considered is 120 m high and has an elliptical base and ratios of height-to-half-width of 0.2 and 0.4 along its major and minor axes. The results obtained show that amplification occurs at and near the top of the hill over a broad range of frequencies. For incident shear waves polarized along the short dimension of the hill the amplification at the top reaches 100% around 10 Hz and stays above 50% for frequencies between 1.5 Hz and 20 Hz. For incident shear waves polarized along the direction of elongation of the topography, the maximum amplification occurs between 2 Hz and 5 Hz with values ranging from 50% to 75%. The results also show that the geometry of the topography exerts a very strong directivity on the wave field diffracted away from the hill and. that at some distance from the hill this diffracted wave field consists mostly of Rayleigh waves.

All samples are from the quenched, glassy pumice fragments that occur in the upper and lower portions of the Topopah Spring Tuff (68.7-78.7% SiO (sub 2) ), the Rainier Mesa Tuff (55.0-76.3% SiO (sub 2) ), and the Ammonia Tanks Tuff (57.5-76.3% SiO (sub 2) ) (all SiO (sub 2) values anhydrous). Most of the melt inclusions in this study are in feldspar; a few are in quartz. There are large variations of volatile concentrations in melt inclusions within an individual phenocryst and large variations in melt inclusions in different phenocrysts within a pumice fragment. This finding demonstrates that the volatiles did not reequilibrate after the formation of the ash flow sheet. The volatile contents of most of these melt inclusions represent decompression and loss of some volatiles and therefore do not represent conditions at the time of entrapment. The presence of CO (sub 2) in many inclusions demonstrates that the magma evolved a gas phase in its preeruption evolution. The nonvolatile chemical variations of the melt inclusions from the Rainier Mesa and Ammonia Tanks Tuffs are similar. Melt inclusions from the lower-silica pumice fragments show a wide range of chemical variation and monitor the liquid as it evolved. In both tuffs some melt inclusions are significantly more silica-rich than the matrix glass, and indicate mixing with a more evolved magma. Most melt inclusions from the high-silica pumice fragments from each of these tuffs show little chemical variation and are similar to the matrix glass. The fact that no lower-silica melt inclusions occur in the high-silica pumice fragments supports the model that the high-silica magma did not evolve from the low-silica magma. The maximum H (sub 2) O concentrations of inclusions in each pumice fragment from the Rainier Mesa and Ammonia Tanks Tuffs show a general positive correlation with SiO (sub 2) concentrations of the pumice fragment. No such relationship is observed with the Topopah Spring Tuff. Copyright 1996 by the American Geophysical Union.

AN - 78001836; 8609450 AB - Existing models of chromosome aberrations produced by ionizing-radiation predict equal numbers of dicentrics and translocations if the dose is so low that complex aberrations can be ignored. We show that, for a specific subset of aberrations detected by FISH, dicentric/translocation equality is predicted even at higher doses. Assuming one-colour whole-chromosome painting (with unpainted chromosomes counterstained and centromeres recognizable) the relevant restriction is that the final metaphase pattern be, in the terminology of Simpson and Savage, 'apparently simple'. This means that the painted pattern is required to have the colour/centromere appearance corresponding to a single complete reciprocal exchange but its actual formation, as reflected for example in lengths, is allowed to be more complicated. The restriction to apparent simplicity is significantly less limiting than ignoring all complex aberrations. Our analysis of predicted dicentric/translocation equality in this case uses examples, a combinatorial counting method, Monte Carlo computer programs, and a duality proof. However, we argue that for 'visibly complex' dicentrics or translocations, no similar equality is expected in general. Corresponding experimental results are briefly surveyed. Checking dicentric/translocation equality experimentally can provide a significant test of current chromosome aberration models.

Thurber's (1983) iterative inversion method is used to simultaneously estimate velocities along a three-dimensional grid and hypocentral parameters of local earthquakes. Our data consist of over 12,000 arrival times from more than 1300 earthquakes recorded by stations of a permanent seismographic network in Costa Rica. Our resulting velocity model correlates well with mapped geologic units at very shallow depth and with tectonic features at greater depth. We find low velocities (4.0 to 4.8 km/sec) in the shallow crust (above 10 km) near the active volcanoes and associated with a NW-SE trending late Cretaceous to late Tertiary sedimentary basin southeast of Herradura peninsula. High velocities (5.4 to 5.7 km/see) in the shallow crust correlate with outcrops of late Jurassic to early Tertiary ultramafic ophiolitic units and with basic Tertiary volcanic units. At depths between 20 and 30 km, high velocities (6.8 to 7.2 km/sec) are associated with the subducting Cocos plate under Costa Rica and two prominent low-velocity bodies (6.3 to 6.5 km/sec) are present about 30 km trenchward of the volcanic arc and along the projection of the aseismic Cocos Ridge as it subducts beneath Costa Rica. The thickened oceanic crust of the Cocos Ridge is most likely responsible for its low velocities. The deep low-velocity anomaly located trenchward of the axis of the volcanoes may indicate the presence of a low-density intrusive resulting from an earlier phase of magmatism, possibly the late Miocene episode that produced the Talamanca intrusive complex.

Intermediate-period waveforms from 57 events recorded between February 1982 and November 1985 were used in the final analysis. Receiver functions from similar backazimuths and distances ate very uniform and were stacked to increase the signal-to-noise ratio. At some azimuths (particularly from the west), significant energy is observed in the tangential component, indicating the existence of heterogeneous structure. The calculated velocity profiles are complicated and contain several distinct features that axe consistent between the different stacks. The most obvious features are two strong velocity increases or boundaries in the lower crust. The first of these velocity gradients is between 27 and 32 km, a depth that is often associated with the crust-mantle transition in this region. Forward modeling of the receiver function arrivals associated with this boundary indicates that it has a strike of approximately 280 degrees and a dip of at least 10 degrees to the northeast. The velocity profiles and forward modeling also indicate a low-velocity layer between depths of about 15 and 28 km.

This interchange consisted of a series of structures up to 600-m long; during the 1971 and 1994 earthquakes, several of these structures separated along .expansion joints and collapsed. To analyze the possible causes of failure, we recorded aftershocks at and near the interchange for 2 weeks following the 1994 earthquake. The aftershock recordings reveal a substantial relative spectral amplification (in the 1- to 10-Hz range) of a factor of 3 to 6 for sites located at the interchange (which is situated on sandstone) relative to a nearby rock (gneiss) outcrop site. Sites within the interchange area have a variation in amplification of a factor of 2 to 4 in the 1- to 10-Hz range. Also, substantial secondary arrivals were generated at two locations in the interchange area. We attribute variations in ground motion at the interchange to be due to variations in the composition of the sandstone and to topographic effects. We computed the linear-response strong ground motion for three sites at the interchange from the 1971 and 1994 main events using aftershock recordings of the Northridge earthquake from three sites (the south and north abutments of the southbound connector of Hwy 14 to I-5 and a central location to the interchange) as empirical Green's functions. The same source events are used for all three sites for a particular synthesis so that differences between synthesized strong ground motion are due to differences in location, geology, and topography of the three sites. Source rupture models are obtained from independent studies. We estimate (1) peak acceleration to have been near 1 g for both earthquakes, due to the topographic and geologic conditions and the geometry, of the fault rupture; (2) differential displacement across the north and south extremes of the area from the Northridge earthquake to have been about 70 cm longitudinal and 40 cm transverse to the Hwy 14 to I-5 connector; (3) differential displacement across the north and south extremes of the area from the San Fernando earthquake to have been about 25 cm longitudinal and 20 cm transverse; and (4) relative motion to be fairly incoherent fro frequencies above 0.5 Hz. These observations are attributed to local geologic and topographic conditions and to wave passage effects and could have contributed to collapse of structures during these earthquakes.

Interaction of different types of ground motion and changes in the elastic properties of geological media throughout the propagation path result in a highly nonlinear function. We use neural networks to model these nonlinearities and develop learning techniques for the analysis of temporal precursors occurring in the emerging earthquake seismic signal. The warning system is designed to analyze the first-arrival from the three components of an earthquake signal and instantaneously provide a profile of impending ground motion, in as little as 0.3 sec after first ground motion is felt at the sensors. The proposed warning units can be used for site-specific applications, distributed networks, or to enhance existing distributed networks. By producing accurate, and informative warnings, the system has the potential to significantly minimize the hazards of catastrophic ground motion. Detailed system design and performance issues, including error measurement in a simple warning scenario are discussed in detail.

The rigorous definition of these and other potentials is presented from fundamental thermodynamic principles at the microscopic level and extended to the macroscopic level by averaging over a representative elementary volume. Of special interest is the treatment of adsorptive surface forces and their associated potentials. Porous medium potentials are extended to a domain containing multiple fluid phases and multiple components. A macroscopic motion equation for a fluid phase (Darcy's law) is derived, incorporating the effect of potentials and surface forces. It relates advective fluxes to gradients of macroscopic chemical potentials and temperature. It reduces to the usual form of Darcy's law only when the aqueous phase is sufficiently dilute and temperatures are uniform. Kelvin's law, which relates relative humidity to matric potential, is extended to the case of multiple multicomponent fluid phases in a porous medium domain. The concept of "irreducible" (or "residual") wetting fluid saturation and its relationship to capillary pressure, surface forces, and the Gibbs chemical potential, are discussed. Common methods for determining the matric potential are reexamined in light of this work. Copyright 1996 by the American Geophysical Union.

AN - 78524124; 8908184 AB - Trisomy in the human appears to be predominantly associated with maternal age. The maternal-age effect, however, shows considerable variability across affected chromosomes. Chromosome-specific variation has been reported in the shapes of the maternal-age-effect curves, including very small effects for the large chromosomes (groups A and B), linear increases (chromosome 16), and exponential increases (chromosome 21). There is also variation among chromosomes in whether the segregation errors occur predominantly at maternal meiosis I, meiosis II, and/or postfertilization mitotic divisions. There is also limited epidemiological evidence for a paternal-age effect, which was recently supported by the findings of age-related increases in sperm aneuploidy using fluorescence in situ hybridization methods. The paternal-age effect is considerably smaller than the maternal and is more likely to involve meiotic II errors of the sex chromosomes, whereas the maternal-age effect is more likely to arise from meiotic I errors producing autosomal trisomies. These and other differences suggest that constitutional aneuploidy arises by multiple mechanisms that may affect (1) the nature and timing of an initiating lesion affecting the oocyte or sperm; (2) the cellular physiology of the time of the nondisjunction event at meiosis I, II, or postfertilization; and (3) the selection against specific chromosomal aneuploidies during embryonic development. Multidisciplinary research is needed to understand the maternal and paternal-age effects on aneuploidy, to (1) identify and characterize the genes that control meiosis, recombination, and segregation; (2) identify the micro-environmental factors around the oocyte and mole germ cells that are involved in the age effects; (3) develop a laboratory animal model for the age effects; (4) characterize the role of genetics, physiology, and environmental toxicology for the paternal-age effects; and (5) identify cohorts of men and women of differing ages who have been exposed to high doses of candidate aneugens and conduct epidemiological investigations of aneuploidies transmitted to their offspring.

AN - 78403108; 8844988 AB - The chromosomal effects of chloral hydrate (CH) on germ cells of male mice were investigated using two methods to detect and characterize spermatid micronuclei (SMN); (a) anti-kinetochore immunofluorescence (SMN-CREST) and (b) multicolor fluorescence in situ hybridization with DNA probes for centromeric DNA and repetitive sequences on chromosome X (SMN-FISH). B6C3F1 mice received single intraperitoneal (i.p.) injections of 82.7, 165.4, or 413.5 mg/kg and round spermatids were sampled at three time intervals representing cells treated in late meiosis, early meiosis, or as spermatogonial stem cells. No increases in the frequencies of SMN were detected for cells treated during meiosis using either SMN-CREST or SMN-FISH methods. After spermatogonial stem-cell treatment, however, elevated frequencies of SMN were detected by both methods. With SMN-FISH, dose trends were observed both in the frequencies of spermatids containing micronuclei and in the frequency of spermatids carrying centromeric label. These findings corroborate the recent report by Allen and colleagues [Allen JW et al.(1994): Mutat. Res. 323:81-88] that CH treatment of spermatogenic stem cells induced SMN. Furthermore, our findings suggest that chromosomal malsegregation or loss may occur in spermatids long after CH treatment of stem cells. Further studies are needed to understand the mechanism of action of the CH effect on stem cells and to determine whether similar effects are induced in human males treated with CH.

AN - 78114206; 8665874 AB - A set of 16 mutagenic aminoimidazo-azaarenes, including four that have been isolated from cooked foods and identified as bacterial mutagens and rodent carcinogens, was selected from a larger series previously published [Hatch et al. (1991): Environ Mol Mutagen 17:4-19] for an in-depth structure-activity study using computational methods. Structural features believed to affect mutagenic potency were tabulated. Molecular orbital energies and other electronic properties of these compounds were calculated using Huckel, semiempirical AM1, and ab initio quantum mechanical methods. Factor interrelationships were studied by multiple linear regression and canonical correlation analyses. Our goal was an improved understanding of the chemical basis of mutagenicity for this class of heterocyclic amines. The major findings were as follows: 1) mutagenic potency is related to the size of the aromatic ring system; 2) potency is enhanced by the presence and location of an N-methyl group; 3) potency is enhanced by addition of ring nitrogen atoms in pyridine, quinoline, and quinoxaline configurations; 4) potency is inversely related to the energy of the LUMO (lowest unoccupied molecular orbital) of the parent amines; 5) potency is directly, though weakly, related to the LUMO energy of the derived nitrenium ions; and 6) the calculated thermodynamic stability of the nitrenium ions (relative to the parent amine) is directly correlated with nitrenium LUMO energy and with the negative charge on the exocyclic nitrogen atom. Although this study raises several intriguing issues relating mutagenicity to chemical properties, further study will be required to determine the plausibility of the nitrenium ion as the ultimate mutagen for binding to DNA.

(super 26) Al/ (super 27) Al ratios of the leachates are 3 + or - 10 X higher than those ratios in total sediment samples. The results show average total Be of 43.7 + or - 5.5% and total Al 16.9 + or - 5.3% in authigenic sediments dated by (super 230) Th as representing the last 7500 yr of deposition. Authigenic (super 10) Be/ (super 9) Be ratios are similar to those of deep waters at the site. Estimated (super 26) Al/ (super 27) Al ratios in detrital sediments (up to 10 (super -15) ) indicate that the source of (super 26) Al in the ocean lies in the atmosphere, but the deposition flux of (super 10) Be is approximately 3 X higher than the atmospheric input indicating lateral transport of (super 10) Be from the ocean to the study area of relatively high particle flux. A decrease in the Be and Al isotopic ratios at approximately 6000 yr may indicate windblown particles to this area of the N Pacific.

Glass, a thermodynamically metastable solid, reacts with water to form a more stable assemblage of secondary minerals. Waste glass in a repository can be expected to come into contact eventually with local groundwater, making it important to understand how this reaction takes place: what species dissolve into solution, adsorb onto mineral surfaces, or precipitate to form new minerals. Geochemical modeling can complement experimental studies in predicting the consequences of glass-water interaction. Using numerical modeling techniques, we attempt to reproduce the results of dissolution experiments performed using simple and complex glass compositions. In the model, the glass dissolves irreversibly into the fluid, forming an altered layer of secondary minerals. The fluid and altered layer together maintain a state of partial equilibrium. We validate the model by comparing the calculated fluid compositions to chemical analyses made over the course of experimental studies. In the case of the simple glass, the predicted altered layer is composed of Ca and Na clinoptilolite, prehnite, analcime, and calcite. For the complex glass, which contains more oxide components than the simple glass and includes radioactive nuclides, the final mineral assemblage is composed predominately of Na clinoptilolite with small amounts of zeolites, chain and sheet silicates, and oxide minerals. The modeling reproduces most of the salient features of the dissolution experiments, suggesting that theoretical calculations can provide a valuable adjunct to experimental studies of glass dissolution.

This report is the data input report for the Programmatic Environmental Impact Statement (PEIS). The PEIS examines the environmental, safety, and health impacts of implementing each disposition alternative on land use, facility operations, and site infrastructure; air quality and noise; water, geology, and soils; biotic, cultural, and paleontological resources; socioeconomics; human health; normal operations and facility accidents; waste management; and transportation. This data report is prepared to assist in estimating the environmental effects associated with the construction and operation of a Deep Borehole Disposal Facility, an alternative currently included in the PEIS. The facility projects under consideration are, not site specific. This report therefore concentrates on environmental, safety, and health impacts at a generic site appropriate for siting a Deep Borehole Disposal Facility.

Construction of the Mayak facility began in 1945 and was completed in 1948. Initially this complex consisted of three main parts: Reactor plant, radiochemical facility, and waste-management facilities. The major sources of radioactive contamination were the discharges of 2.7X10 (super 6) Ci of liquid wastes into the Techa River (1949-1956); an explosion in the radioactive waste storage facility in 1957 (the so-called Kyshtym Accident) that formed the East Urals Radioactive Trace (EURT) due to dispersion of 2X10 (super 6) Ci into the atmosphere; and gaseous aerosol releases (about 560,000 Ci of (super 131) I in total) within the first decades of the facility's operation. The significant portion of activity for the Techa River and EURT consists of long-lived radionuclides, mainly (super 90) Sr. These releases resulted in the long-lived contamination of surrounding territories. The predominant radionuclide for operating gaseous aerosol releases was short-lived (super 131) I resulting from reprocessing of nuclear fuel. The maximal annual rates, which occurred in 1952-1953, were reconstructed on the basis of technological records by the Mayak team.

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.

Ground water containing various anions and cations are passed through a stack of carbon aerogel electrodes, each having a very high specific surface area and exceptionally low electrical resistivity. After polarization of the stack, impurity ions are removed from the electrolyte by the imposed electric field and adsorbed on the electrode surfaces. Field tests have shown that hexavalent chromium in the form of HCrO (super 4-) /CrO (sub 4) (super 2-) /Cr (sub 2) O (sub 7) (super 2-) can be selectively removed from contaminated ground water with a 530 ppm total dissolved solids (TDS) background. The concentration of Cr(VI) can be lowered from 35 to 2 ppb. The mechanism for Cr(VI) separation involves chemisorption on the carbon aerogel anode, a process that can be reversed by cathodic polarization. Cr(VI) removal is not based upon simple double-layer charging.

One hundred ninety liters of PCE were released at a rate of 2 liters per hour from a point 0.5 m below ground surface. The spill was conducted within a double walled tank where saturated layers of sand, bentonite and a sand/bentonite mixture were installed. Complex electrical resistance measurements were performed. Data were taken before the release, several times during, and then after the PCE was released. Magnitude and phase were measured at 1 and 64 Hz. Data from before the release were compared with those during the release for the purpose of imaging the changes in conductivity resulting from the plume. Conductivity difference tomographs showed a decrease in electrical conductivity as the DNAPL penetrated the soil. A pancake-shaped anomaly developed on the top of a bentonite layer at 2 m depth. The anomaly grew in magnitude and extent during the release and borehole television surveys data confirmed the anomaly to be free-product PCE whose downward migration was stopped by the low permeability clay. The tomographs clearly delineated the plume as a resistive anomaly.

The monitoring periods were 14 October-14 November 1992, 20 October-15 November 1993, 16 August-3 November 1994, and 17 February-27 February 1995. Pairs of high volume air samplers were located at each of four locations of the process stream: the "spoils pile" that was the feedstock, the "plant area" near the hot soil gate of the sorter, the "clean pile" conveyer area where sorted clean soil was moved, and the "oversize soil" crushing area. These locations were monitored only during the working hours, while air monitoring was also done at an upwind, "background" area 24-hours per day. The median concentrations of Pu in "workplace" air (combined spoils pile, plant area, and clean pile sites) in 1992 was 397 aCi/m (super 3) (15 mu Bq/m (super 3) ), but increased to median values of 23000 aCi/m (super 3) (852 mu Bq/m (super 3) ) in August-November 1994 and 29800 aCi/m (super 3) (1100 mu Bq/m (super 3) ) in February 1995. The highest median value at the worksites (29800 aCi/m (super 3) ) was more than 200 times lower than the regulatory level. The highest observed value was 84200 aCi/m (super 3) at the spoils pile site, and this was more than 70 times lower than the regulatory level. The conclusion was that, in spite of the dusty environment, and the increased level of specific activity, we did not find that the soil processing posed any significant risk to workers during the observation periods 1992-1995.

Frequently these tanks are found to leak, thereby resulting in not only a loss of stored inventory, but in contamination to soils and groundwater. It is important to develop a reliable method of detecting leaks before large quantities are emitted into the environment surround the tanks. Two field experiments were performed to evaluate the performance of electrical resistance tomography (ERT) as a leak detection method under metal underground storage tanks (UST). This paper provides a summary of the field experiments performed under a 15 m diameter steel tank mockup located at the Hanford Reservation.

The SVE system was proposed to remediate unsaturated soil containing volatile organic compounds (VOCs), primarily trichloroethylene (TCE). To solve the problem of active fluid and gas flow under unsaturated and saturated conditions, the numerical, multiphase, multicomponent computer code, NUFT (Nonisothermal Unsaturated-Saturated Flow and Transport), was used. NUFT is capable of simulating the non-isothermal flow and transport of multiple phases and contaminants in 3-dimensions using finite-difference grids with cartesian or cylindrical coordinates. The code is a valuable tool to guide the design of remediation systems that apply technologies such as soil vapor extraction (SVE), air sparging, steam injection, and ground water pump-and-treat. At LLNL, NUFT was used to quantify the potential impact of VOCs in unsaturated soil on ground water as a result of migration processes dominated by gaseous diffusion, and to evaluate the efficiency and long-term performance of a single-well SVE system under heterogeneous site conditions. Site-specific soil cleanup goals were developed based on the modeling results. The modeling results stress the importance of including soil heterogeneities in the analysis. Fast mass removal proved to be strongly correlated with high air flow velocities and flushing rates, which are generally associated with high-permeability soil strata. While field measurements of the pressure gradient are commonly used to estimate the zone of influence of a SVE system, modeling provides a unique tool to evaluate channeling effects and better predict system efficiency under heterogeneous site conditions.

Assuming that the quartz vein suffered mass wastage soon after any exposure resulting from soil erosion, we obtain model erosion rates of > or =3X10 (super -3) and < or =3X10 (super -4) cm yr (super -1) for the nuclides (super 14) C and (super 10) Be respectively. The implications of these results are discussed both in terms of plausible recent erosion histories of the soil profile, and also the applicability of the quartz vein method and its variants for determining soil erosion rates. We conclude that the two radionuclides together should generally prove useful for determining soil erosion rates in quartz containing rock fragments. By itself, the nuclide (super 14) C should be useful for determining erosion rates exceeding approximately 5X10 (super -2) cm yr (super -1) .

Analysis of stress orientation data from additional wells located >1O km from the fault confirm previous observations that S (sub Hmax) stresses are at high angles to the fault trend, consistent with low shear stress on the San Andreas. We suggest that the overall variation in S (sub Hmax) direction with distance from the San Andreas Fault indicates that shear stresses resolved onto the fault may be depth dependent, with greater shear stress at shallower depths. Alternatively, these stress rotations observed In the vicinity of the San Andreas might also reflect the influence of local secondary faulting and folding, variations in lithology and/or slip heterogeneties associated with the 1857 M8+ Fort Tejon earthquake. Estimates of crustal pore pressure inferred from drilling mud-weights and drill-stem tests from wells in the vicinity (<10 km) of the San Andreas Fault indicate near-hydrostatic conditions to depths of about 5 km. However, 20-30 km from the San Andreas Fault and within the central portions of the southern San Joaquin Valley, crustal pore pressures approach 60% of the lithostatic load starting at about 3.5 km depth. Thus, our data close to the fault suggests that elevated fluid pressures within the fault zone, as proposed to explain the long-term low-strength of the San Andreas, either do not penetrate far into the adjacent crust and/or are confined largely to deeper portions of the fault zone.

The ground water in these sediments contains multiple plumes of contaminants consisting predominantly of volatile organic compounds (VOCs). To better evaluate the hydrogeologic factors controlling subsurface flow and transport of VOCs for the design and implementation of remediation systems, we subdivided the subsurface into hydrostratigraphic units (HSUs). The HSUs have similar hydraulic characteristics based on a methodical analysis of lithology, structure, geophysical logs, VOC distributions, aquifer tests, and water levels. We constructed maps and cross sections showing the changes in the plumes through time. To aid in well field design, these maps and cross sections were then analyzed with respect to hydrogeologic factors, such as hydraulic gradients and geometry of the high-permeability pathways within each HSU. This approach enables us to better position extraction wells and piezometers to optimize VOC mass removal and ensure adequate hydraulic capture of the VOC plumes. We reduced the number of wells originally proposed for the site by demonstrating to the regulatory agencies the hydraulic communication within the HSUs. This work has also provided input parameters to a 3D numerical model and assisted in evaluating the feasibility of using new, innovative technologies at the site. Such subsurface characterization allows us to better evaluate the effectiveness of the ground water cleanup program and reduce long-term closure costs while meeting the requirements of the Record of Decision for the site.

The partition coefficient (K (sub D) ) was determined at temperatures from 25 degrees to 350 degrees C, at 800 bars, and this information was applied to reconstruct pore water B and delta (super 11) B in ODP drill sites, where pH, T, and porosity are known. The partition coefficient of B is a function of temperature, pH, and sediment mineralogy. The solution pH exerts a dominant control at low temperatures; however, K (sub D) decreases to a value of essentially zero (compared to that of K (sub D) = approximately 3.5 at 25 degrees C) at high temperatures indicating no adsorption. Two empirical equations were derived to represent most of the available experimental results. For pelagic clay rich sediments, a K (sub D) = -3.84-0.020T+0.88pH (R = 0.84; 1 = 0.25) is established. For sediments that have experienced progressive metamorphism, a K (sub D) = -1.38-0.008T+0.59pH (R = 0.81; 1 = 0.37) can be applied. Similarly the effect on pore water delta (super 11) B can be corrected if the fractionation factors at different temperatures are assumed. The corrected B and delta (super 11) B in ODP Sites 671, 672, and 808 indicate significant mobilization of bulk B in sediment (exchangeable+lattice bound) at depth, especially near the decollement zone or other potential flow conduits. Tectonically expelled fluids from mud diapirs of Barbados Ridge Complex, hot springs of Rumsey Hills, California, and mud pot waters of the Salton Sea geothermal field, are enriched in B (up to 20 mM) with lower delta (super 11) B, supporting the argument of B mobilization as a result of fluid expulsion in accretionary prisms.

Crystals grown by evaporation of an aqueous solution form in the monoclinic space group P2 sub(1)/n with two molecules of PhIP per asymmetric unit, along with six water molecules. The phenyl groups of these two PhIP molecules have torsion angles of different magnitude with respect to the plane of the imidazopyridine moiety. To maintain centrosymmetry, the crystal also contains an oppositely torsioned symmetry equivalent of each. The amino groups of both PhIP molecules take part in an extensive hydrogen bond network with the water of crystallization, forming long channels through the crystals parallel to the crystallographic b axis. The diffraction results are compared to theoretical calculations of the optimized geometry for a single PhIP molecule in vacuo as well as with water hydrogen-bonded to the exocyclic amine. In general, the agreement between the X-ray crystal structure of PhIP and its theory-derived counterpart in vacuo is within the combined experimental-theoretical uncertainty. The C-N bond to the exocyclic amine and the neighboring C=N imidazole bond are exceptions. This is attributed to the combined neglect of the crystal environment, waters of hydration, and the lack of coplanarity between the imidazole ring and the amine group in the calculations. To address the effect of waters of hydration, additional calculations were performed to optimize the geometry of a PhIP molecule with two water molecules hydrogen-bonded to the exocyclic amine. The resulting C-N exocyclic amine and C=N imidazole bond lengths were closer to those obtained by X-ray diffraction. The accord between theory and experiment demonstrates the utility of applying theory to (1) accurately predict structures of PhIP metabolites and intermediates that are too labile for study by conventional structural techniques such as X-ray crystallography and (2) assist in studying the mechanisms by which PhIP and its metabolites interact with proteins and DNA.

Frequencies were evaluated in 2 steps. The first assigned a provisional frequency based on at least 8 previous samples by examining yearly trends of data normalized to the drinking water standard. The second step evaluated recent to overall trends to locate instances where the previously assigned frequency should be reconsidered. Statistical tests were not applied because it was unlikely that reasonable statistical power would be achieved on this kind of data. The usual quarterly sampling frequency was modified on the basis of this approach. When applied to 2 sampling schedules, this approach yielded savings of around 30 per cent in each case.

About 5.4 kg dry weight of the bacteria were suspended in 1800 litres of groundwater and injected into the aquifer through a single well at 27 m, several metres below the water table. The groundwater contained no TCE; it was buffered with a phosphate solution and contained phenol red tracer. The average porosity and permeability of the aquifer material were 40 per cent and 3 um2, respectively. Approximately 50 per cent of the injected bacteria attached to the sediments, forming an in-situ fixed bed reactor of unknown geometry. Contaminated groundwater was withdrawn through the biofilter region by extracting at 3.8 litres per minute for 30 h then at 2.0 litres per minute for the remaining 39 d of the field experiment. TCE concentrations were reduced by 98 per cent in the first 50 h of the withdrawal. TCE concentrations extracted through the biofilter gradually increased to background values by the end of the experiment. There are 31 references.

M. edulis and S. purpuratus were exposed to total sulphide concentrations of 10-640 ug per litre, R. abronius was exposed to 0-2.5 mg per litre, and E. estuarius was exposed to 0.01-4.35 mg per litre in flow-through systems for 48 h. Abnormal development of M. edulis and S. purpuratus embryos was positively associated with increasing sulphide concentrations. Normal development of M. edulis and S. purpuratus was inhibited at 256 and 640 ug total sulphide per litre, respectively. Complete mortality of R. abronius and E. estuarius occurred at 2.5 and 4.35 mg total sulphide per litre, respectively.

Into repair-deficient UV5 cells we introduced cDNAs for expressing cytochrome P450IA2 and acetyltransferases. We then genetically reverted these transformed lines to obtain matched metabolically competent repair-deficient/proficient lines. For a high mutagenic response, we find a requirement for acetyltransferase with 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) but not with 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). This system allows for both quantifying mutagenesis and analyzing the mutational spectra produced by heterocyclic amines.

AN - 77718025; 7493812 AB - Based on the DS86 dosimetry system, nearly all of the dose to survivors of the atomic bombings of Hiroshima and Nagasaki was due to unusually high-energy gamma rays, predominantly in the 2- to 5-MeV range. These high energies resulted in part from neutron capture gamma rays as the bomb neutrons penetrated large distances of air. Because of the inverse relationship between energy and biological effectiveness, these high-energy gamma rays are expected to be substantially less effective in producing biological damage than the radiations commonly used in radiobiology and risk assessment.

The Pb isotope ratios of Klyuchevskoy basalts ( (super 206) Pb/ (super 204) Pb = 18.26-18.30, (super 207) Pb/ (super 204) Pb = 15.45-15.48, (super 208) Pb/ (super 204) Pb = 37.83-37.91) define a narrow range that falls within the Pacific mid-ocean ridge basalt (MORB) field and are among the least radiogenic island arc basalts measured to date. These data are similar to data from three other Quaternary Kamchatkan volcanoes: Tolbachik, Kumroch-Shish, and Maly Semiachik. In contrast, North Pacific sediments (primarily siliceous oozes) collected parallel to the Kamchatkan trench during Ocean Drilling Program Leg 145, have Pb isotope ratios ( (super 206) Pb/ (super 204) Pb = 18.51-18.78, (super 207) Pb/ (super 204) Pb = 15.56-15.64, (super 208) Pb/ (super 204) Pb = 38.49-38.75) that are more radiogenic than either the Klyuchevskoy basalts or Pacific MORB. Incorporation of even a small amount of sediment in the source of the Klyuchevskoy magmas would shift the Pb isotope ratios of the erupted basalts from the MORB field to more radiogenic values. The absence of (super 10) Be and elevated Pb isotope ratios in the Kamchatkan volcanic lavas, despite the presence of distinctively radiogenic Pb in the North Pacific sediments makes it unlikely that sediments or sediment-derived fluids are involved in the source magmas beneath Kamchatka. The Kamchatkan arc thus represents an "end-member" whereby little or no sediment is involved in terms of elemental recycling and arc magma genesis. The major and trace elements, Pb, Sr and Nd isotope data of the Kamchatkan basalts are most consistently explained if derived from a fluid-fluxed, peridotitic mantle wedge source, wherein the fluid composition is dominantly controlled by dehydration of altered oceanic crust, imparting a radiogenic (super 87) Sr/ (super 86) Sr, and MORB-like Pb isotope signature to the mantle source. The erupted Klyuchevskoy lavas preserve a slab signature derived from incompatible elements that are strongly partitioned into the fluid. The 30 km of arc crust through which the Klyuchevskoy magmas traverse prior to eruption is not composed of older crust, but must be juvenile, similar in isotopic composition to MORB.

The generalization from the single-porosity case increases the number of independent coefficients for volume deformation from three to six for an isotropic applied stress. The physical interpretations are based upon considerations of different temporal and spatial scales. For very short times, both matrix and fractures behave in an undrained fashion. For very long times, the double-porosity medium behaves like an equivalent single-porosity medium. At the macroscopic spatial level, the pertinent parameters (such as the total compressibility) may be determined by appropriate field tests. At an intermediate or mesoscopic scale, pertinent parameters of the rock matrix can be determined directly through laboratory measurements on core, and the compressibility can be measured for a single fracture. All six coefficients are determined from the three poroelastic matrix coefficients and the fracture compressibility from the single assumption that the solid grain modulus of the composite is approximately the same as that of the matrix for a small fracture porosity. Under this assumption, the total compressibility and three-dimensional storage coefficient of the composite are the volume averages of the matrix and fracture contributions.

Standard regional discrimination techniques have many shortcomings. For example, they cannot always discriminate shallow, low-magnitude earthquakes or mining-related events. I show that slopes of P- to S-wave spectral ratios can be used to discriminate shallow- and normal-depth earthquakes from explosions and possibly to discriminate explosions from mining-related rockburst or collapse events. P- to S-wave slopes and conventional, high-frequency P- to S-wave spectral amplitude ratios discriminate even better in combination than alone. A comparison of Pn and Lg spectra from Nevada Test Site (NTS) explosions and earthquakes shows that this method discriminates concentrated explosions from earthquakes and other shallow seismic events such as mine collapses because S waves from explosions decay more rapidly at high frequencies than do S waves from earthquakes. Spectra of one-dimensional reflectivity synthetic seismograms show that frequency-dependent attenuation of explosion-generated P- to S-wave converted phases, in the near-surface layers, may be responsible for the differences in Lg (S-wave) spectral falloff. These simulations also show that absolute amplitudes of earthquake P- to S-wave spectral ratios are very sensitive to mechanism and depth, which may help explain the variable performance of conventional methods.

The frequent technical use of glass and the abundance of glass at the earth's surface make this process one of the most important weathering reactions. In particular the alteration of volcanic glass provides a direct pathway for mantle-derived materials into the hydrosphere. To begin understanding the kinetics of these processes, we carried out three experiments exposing to seawater polished surfaces of nuclear-waste glass. The durations of experiments were: 410 days with continuously flowing sand-filtered, unsterilized seawater (approx. 2X10 (super 6) l; Exp. 1), 126 days with a marine cyanobacterium culture (50 ml, Exp. 2), and for 225 days under sterile conditions (250 ml, Exp. 3). The sterile experiment (Exp. 3) did not show significant signs of alteration. Exp. 1 resulted in development of a several mu m thick biofilm and surface corrosion with grooves exceeding 10 mu m in length and 0.5 mu m in width. Cyanobacterial cultures also developed a biofilm on the glass surfaces, thinner than in Exp. 1. The glass surfaces themselves were corroded with approximately 0.5-mu m-sized pits clustering in 5 mu m broad zones parallel to the polishing direction. These experiments show that biofilms develop within months and the corrosion of glass is enhanced by the presence of bacteria. The time scales of biologically mediated glass corrosion are fast when compared to most geological processes. We expect that volcanic ash is rapidly colonized in the oceanic water column, in deep-sea sediments, and in soils. The biological degradation of basaltic glass may contribute significantly to the oceanic nutrient cycle, the chemical exchange between bottom waters and marine sediments, and the fertility of volcanic soils.

AN - 77706155; 7502995 AB - This case study describes an indoor environment investigation initiated in response to numerous health and comfort complaints suspected of being associated with a two-story office building. Conventional indoor environment investigation techniques were applied in an attempt to identify one or several contributing factors, such as inadequate outdoor air ventilation and the presence of a respiratory irritant. The air quality satisfaction percentage in the building was well above 80%; however, at least one individual was experiencing a fairly severe reaction only upon entering the subject building. Evaluating the building indoor conditions as acceptable without attempting to address all possible building-related causes and communicating findings to interested occupants would likely have resulted in more occupant complaints and increased the potential for hysteria conditions. This investigation necessarily addressed a sensitive individual and involved an occupational physician as a constructive participant in the investigation.

All 10 large spherules collected in glacial till at Lewis Cliff are extraterrestrial. As in earlier work, the great majority of particles show prominent solar cosmic-ray production of (super 2) 6Al, indicating bombardment ages on the order of 10 (super 6) years or even longer. These long ages are in direct contradiction to model ages for small particles in the inner solar system and may require reconsideration of models of small particle lifetimes. A small fraction of the particles so far measured (6/42) possess cosmogenic radionuclide patterns consistent with predictions for meteoroid spall droplets. Presumably, most of the spherules were bombarded in space primarily as bodies not much larger than their present size. (Auth. mod.)

Increases in frequency dictated by remedial actions are left to the judgement of personnel reviewing the recommendations. To become more applicable throughout the life cycle of a ground water cleanup project or for compliance monitoring, several improvements are envisioned, including: chemical signature analysis to identify minimum suites of contaminants for a well, a simple flow and transport model so that sampling of downgradient wells are increased before movement of contamination, and a sampling cost estimation capability. By blending qualitative and quantitative approaches, we hope to create a defensible system while retaining interpretation ease and relevance to decision making.

These tests are being conducted with reference glass compositions doped with neptunium, plutonium, and americium from the Defense Waste Processing Facility (DWPF) and the West Valley Demonstration Project (WVDP), and have been ongoing for over 8 years. Solution compositions, including transuranics, have been periodically determined, and selected analyses of colloid formation and composition, glass corrosion layers, and solid alteration phases have been obtained by scanning and analytical transmission electron microscopies. The importance of integrated testing has been demonstrated, as complex interactions among the glass, the groundwater, and the sensitized stainless steel have been observed. The cumulative releases of both glass-forming and dopant elements are presented along with identification of reaction phases and their partitioning between solution and solid phases. Alteration phases, including smectite clay, iron silicates, uranium silicates, and calcium thorium phosphate, have been observed forming on the glass and stainless steel and have occasionally been found suspended in solution as colloids. Actinides, except neptunium, concentrate into alteration phases or sorb onto the stainless steel. The subsequent transport of the actinides is then controlled by these phases.

The models used are (1) a modified version of the Geophysical Fluid Dynamics Laboratory modular ocean model (MOM) configured with simple horizontal subgrid-scale mixing of tracers; (2) the same model using the Gent and McWilliams (1990) subgrid-scale tracer transport parameterization, which includes isopycnal mixing; and (3) the ocean isopycnal (OPYC) model of J. M. Oberhuber, which uses isopycnal subgrid-scale mixing of tracers within an isopycnal coordinate system. In addition, we perform another MOM simulation which illustrates the sensitivity of the results to the thickness of the surface mixed layer. To minimize differences in the results due to differences in forcings, all our simulations use the same formulations for surface fluxes of heat and fresh water and the same sea ice model. In addition, the numerical grids are all nearly the same. Comparison of our model results to revised estimates of oceanic bomb (super 14) C from the Geochemical Ocean Sections Study observations and to annual mean temperature observations shows that our results are sensitive to the models' treatments of subgrid-scale mixing of tracers and to the thickness of the surface mixed layer. Since the simulated vertical profiles of bomb (super 14) C or temperature alone can be brought close to the observed profile by adjusting model parameters, we judge the realism of modeled vertical transport by how well vertical profiles of both bomb (super 14) C and temperature can be simulated with one set of parameter values. By this standard, OPYC does better than our baseline configuration of MOM, which we attribute to the unrealistic treatment of subgrid-scale mixing of tracers and of the surface mixed layer in this simulation. We illustrate this by showing that the use of the Gent and McWilliams tracer transport parameterization results in a markedly improved vertical temperature profile and almost no change in the bomb (super 14) C distribution, compared with our baseline MOM simulation. Finally, we show that increasing the effective mixed layer thickness in MOM from 30 to 76 m results in a slightly more realistic vertical profile of bomb (super 14) C but a slightly less realistic temperature profile.

Previous seismological studies within this region have had to rely on earthquakes recorded almost exclusively at stations outside of the plateau. We have the opportunity to study numerous source-receiver paths confined entirely within the Tibetan Plateau. Our analysis concentrates on travel time, amplitude, and frequency content measurements of the Pg, Pn and Sn phases. Pn can be clearly picked for all observed paths and propagates at an average velocity of 8.16+ or -0.07 km/s within the Tibetan Plateau. Sn, however, shows dramatic variations in propagation efficiency across the Tibetan Plateau that is strongly dependent on frequency. We observe that Sn rapidly decreases in frequency and amplitude as it passes through the northern portion of the plateau. We show that in general, Sn propagation efficiency decreases with increasing frequency content. We use 122 events from outside of the plateau and 61 from within to refine the boundaries of a region of inefficient high-frequency Sn propagation. Specifically, we show that a larger portion of the northern Tibetan Plateau attenuates Sn energy than was previously suggested. In the southern plateau, where high-frequency Sn is observed, we computed an average velocity of 4.59+ or -0.18 km/s. We also observed that the Pn velocity within this region of inefficient high-frequency Sn propagation is nearly 4% slower than the Pn velocity computed for paths restricted to the southern plateau and that the crust is about 10 km thinner than in the south. The coincident locations of inefficient Sn propagation and slow Pn velocity is commonly observed in regions of active tectonics. Our results add constraints to the velocity structure of the lithosphere beneath the Tibetan Plateau and require first-order lateral variations in the uppermost mantle structure, despite the relatively uniform topography of the plateau.

Garnet/fluid and clinopyroxene/fluid partition coefficients for Pb, Ce, Nd, Sm and Yb were measured by loading trace element dopant with garnet or clinopyroxene and fluid (H (sub 2) O + NaCl) and excess SiO (sub 2) + albite ( approximately 3 wt.%) in welded Pt capsules. The results confirm that low-Ce/Pb fluids coexist with garnet and clinopyroxene during high-P dehydration of altered basalt. Production of subduction-zone magmas from the mantle fluxed by basalt-derived fluid is a mechanism in which relatively Pb-rich, Ce-poor mantle-derived material is added to the continents. The Pb enrichment of the continental margins is thus continuing at convergent margins.

AN - 77589160; 7558838 AB - Environmental monitoring of soils at the U.S. Department of Energy's Lawrence Livermore National Laboratory in California has been conducted for more than 20 years. The purposes of the program are to determine the effects, if any, of LLNL's operations on the surrounding areas near its two separate sites and to determine if there are any long-term trends. Data from 1976 to 1992 were analyzed to determine their appropriate statistical distribution, and differences among locations and changes with time were evaluated. The data generally followed lognormal distributions, and results for 239 + 240Pu and 137Cs data were consistent with previously reported values for world-wide fallout. Although all values for 239 + 240Pu were small, 239 + 240Pu data for locations downwind from the Livermore site were found to be statistically significantly higher than for upwind locations. Results for 238U at Site 300 locations near where 238U is used were significantly higher than background locations. Results for 137Cs and 40K were not significantly different between sites, whereas results for 232Th were significantly higher for Site 300 than for the Livermore site. Doses for all radionuclides were below acceptable levels, and doses for most radionuclides were negligible. Evaluation of trends with time yielded small or statistically insignificant changes for all radionuclides.

AN - 77581001; 7565868 AB - Analysis of two human populations for dependence of somatic mutation on age has revealed both similarities and differences. The studies performed employed peripheral blood lymphocytes and measured the efficiency with which these cells form clones in vitro (cloning efficiency, CE) and the frequency of cells with inactivating mutations of the hypoxanthine phosphoribosyltransferase gene (mutant frequency, MF). The people studied were between 19 and 64 years of age. In one population, composed of 78 never smokers and 140 current smokers from the United States (US), both CE and MF were dependent on age: CE declined with age (p = 0.005); MF increased 0.15 per 10(6) cells per year of age for nonsmokers (p < 0.001) and at 1.3 times that rate for smokers (p = 0.01). In the second population, 80 people of unknown smoking status from Russia, the increase in MF per year was even greater, 2.5 times that of the US nonsmokers (p = 0.001) but the dependence of CE on age was the same as for the US population (p = 0.043). Because the increase of MF of the Russians with age is 2-fold greater than that of the US smokers, the intensity of smoking and/or other environmental exposures, or the susceptibility to these exposures, must account for the difference in age dependent MF increase, not the proportion of Russians that are smokers. Differences in the lymphocyte subpopulations that survived the longer transit from Russia may have contributed to the observed differences in MF. However, overall, the mutant frequency results suggest that the Russians were chronically exposed to higher levels of agents that induce somatic mutation and that, on an age adjusted basis, the Russia population studied is at increased risk for health consequences from accumulated genetic damage.

AN - 77579147; 7565886 AB - Individual responses to the aging process are variable and are affected by genetic as well as environmental factors. Fluorescent in situ hybridization with whole chromosome probes ('chromosome painting') provides an efficient approach for detecting structural chromosome aberrations in human lymphocytes. This rapid and sensitive technique is an effective tool for quantifying chronic exposure to environmental agents which may result in an accumulation of cytogenetic damage with age. We have applied this technology to a normal, putatively unexposed, population to document the relationship between age and the accumulation of cytogenetic damage, as well as to establish a baseline frequency of stable aberrations. Using probes for chromosomes 1, 2 and 4 simultaneously, the equivalent of 1000 metaphases was scored for stable and unstable aberrations from each of 91 subjects ranging in age from newborns (umbilical cord bloods; n = 14) to adults aged 19 to 79 years. Each subject (or one parent of each newborn) completed an extensive questionnaire to identify possible lifestyle factors that may influence the frequency of cytogenetic damage. Our findings show a significant increase in stable aberrations (translocations and insertions) with age (p < 0.0001). We also observed age-related increases with dicentrics (p < 0.0001) and acentric fragments (p < 0.0001). Relative to the frequencies observed in cord bloods, the frequencies of stable aberrations, dicentrics, and acentric fragments in adults aged 50 and over were elevated 10.6-fold, 3.3-fold, and 2.9-fold, respectively. Nine variables other than age are significantly associated with the frequency of stable aberrations; these are: smoking (two variables), consumption of diet drinks and/or diet sweeteners (4 variables), exposure to asbestos or coal products (1 variable each), and having a previous major illness (1 variable). Newborns whose mothers smoked during pregnancy had a 1.5-fold increase in stable aberrations (p = 0.029). Repeat samples from a subset of the adults indicate that for most subjects there is little change in individual translocation frequencies over a period of two to three years. These results support the hypothesis that stable chromosome aberrations show a greater accumulation with age than do unstable aberrations and suggest that lifestyle factors contribute to the accumulation of cytogenetic damage.

Maracaibo basin, Venezuela. Kinetic parameters were determined by pyrolysis experiments. The model predicts that four adjacent regions have distinct history of oil generation: the NE region generated during the late Eocene (48-40 m.y.), the N central region generated during late Eocene and again from late Miocene to present (8-0 m.y.), the S region generated from late Miocene to early Pliocene (8-2 m.y.) and NW region generated late Miocene to present (12-0 m.y.) The important variables affecting expelled oil quality are porosity during generation and initial TOC. Higher maturates favour higher oil gravity, higher oil saturate content, and lower oil sulphur content. Agreement between observation and prediction of physical parameters (e.g. P) and Rock-Eval parameters (e.g. H/C, T (sub max,) etc.) are good, whereas predictions of the amount of hydrocarbon generated and hydrocarbon composition are fair.

Experiments conducted at 1000 degrees C and 1.5 GPa yielded large crystals free of compositional zoning. Partition coefficients were found to be constant at total concentrations ranging from approximately 1 to >100 ppm, indicating Henry's Law is operative over this interval. Comparison of partition coefficients measured in this study with previous determinations yields good agreement for similar compositions at comparable pressure and temperature. The compatibility of U, Th and Pb in amphibole decreases in the order Pb>Th>U. Partial melting or fractional crystallization of amphibole-bearing assemblages will therefore result in the generation of excesses in (super 238) U activity relative to (super 230) Th, similar in magnitude to that produced by clinopyroxene. The compatibility of Pb in amphibole relative to U or Th indicates that melt generation in the presence of residual amphibole will result in the long-term enrichment in Pb relative to U or Th in the residue. This process is therefore incapable of producing the depletion in Pb relative to U or Th inferred from the Pb isotopic composition of MORB and OIB. Comparison of partition coefficients measured in this study with previous values for clinopyroxene allows some distinction to be made between expected trace-element fractionations produced during dry (cpx present) and wet (cpx+amphibole present) melting. Rb, Ba, Nb and Ta are dramatically less compatible in clinopyroxene than in amphibole, whereas Th, U, Hf and Zr have similar compatibilities in both phases. Interelement fractionations, such as D (sub Nb) /D (sub Ba) are also different for clinopyroxene and amphibole. Changes in certain ratios, such as Ba/Nb, Ba/Th, and Nb/Th within comagmatic suites may therefore offer a means to discern the loss of amphibole from the melting assemblage. Elastic strain theory is applied to the partitioning data after the approaches of Beattie and Blundy and Wood and is used to predict amphibole/melt partition coefficients at conditions of P, T and composition other than those employed in this study. Given values of D (sub Ca) , D (sub Ti) and D (sub K) from previous partitioning studies, this approach yields amphibole/melt trace-element partition coefficients that reproduce measured values from the literature to within 40-45%. This degree of reproducibility is considered reasonable given that model parameters are derived from partitioning relations involving iron- and potassium-free amphibole.

AN - 77747769; 8544756 AB - The correlation of bacterial mutagenicity with DNA adducts from the heterocyclic amine cooked-food mutagen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) was investigated in Salmonella typhimurium strains TA98 (uvrB deficient) and TA1978 (uvrB proficient). Bacterial cells were exposed to PhIP using a modification of the Ames/Salmonella microsuspension assay. Half of the cells, generated from a 90 min pre-incubation and washing, were plated for revertant formation while the remaining half was subjected to DNA adduct analysis via 32P-postlabeling. In TA98, DNA adducts were detected at an RAL (relative adduct labeling) of 10 x 10(-7) and 21 x 10(-7) at PhIP concentrations of 5.5 and 17 microM, respectively. This corresponded to 28.8 and 20.9 adducts/revertant, respectively. These values were based on the assumption that only four repeating GC bases within a 75 DNA base region is the gene target site for PhIP induced mutations. In TA1978, no revertants above background were detected at any concentration of PhIP tested. DNA adducts, however, were detected at 11 x 10(-7) and 21 x 10(-7) adducts per nucleotide at 223 and 1116 microM PhIP, respectively. The lack of detectable revertants, but the presence of DNA adducts, suggests pre-mutational lesions did occur during the 90 min pre-incubation. Presumably, when the S9 activating system and PhIP were removed (via washing with phosphate buffered saline) prior to plating, the cells containing an intact uvrB repair system repaired the lesions during the incubation time on the plates. In conclusion, the induction of revertants by adducts appears quite efficient, as approximately 25 adducts are required for one mutational event in the excision repair deficient bacteria.

The safe and secure management and eventual disposition of this plutonium, and of a similar inventory in Russia, is a high priority. A variety of options (both interim and permanent) are under consideration to manage this material. The permanent solutions can be categorized into two broad groups: direct disposal and utilization. Plutonium utilization options have in common the generation of high-level radioactive waste which will be disposed of in a mined geologic disposal system to be developed for spent reactor fuel and defense high level waste. Other final disposition forms, such as plutonium metal, plutonium oxide, and plutonium immobilized without high-level radiation sources may be better suited to placement in a custom facility. This paper discusses a leading candidate for such a facility; deep (several kilometers) borehole disposition. The deep borehole disposition concept involves placing excess plutonium deep into old stable rock formations with little free water present. The safety argument centers around ancient groundwater indicating lack of migration, and thus no expected communication with the accessible environment until the plutonium has decayed.

We investigate a possible mechanism proposed by Hirono whereby volcanic eruptions might trigger or enhance El Ninos. Three distributions of volcanic ash aerosol in the troposphere over the eastern Pacific Ocean were used to force simulations with a modified version of the NCAR CCM1 atmospheric general circulation model for the month of April 1982, using observed sea surface temperatures. Only in the case of mid-tropospheric heating is there a strong dynamical reaction in the atmosphere resulting in a weakening of the trade winds in the eastern Pacific Ocean north of the equator, consistent with surface wind observations and with the first part of Hirono's theory. However, the 1982 ENSO event had started before this wind anomaly, and only trade wind collapses in the western equatorial Pacific can initiate El Ninos. The results suggest that, while tropospheric aerosols from volcanic eruptions can influence atmospheric circulation, the timing and location of the El Chichon eruption and the large ENSO event that followed was a coincidence, and that Hirono's mechanism was not responsible for the strength or timing of the El Nino.

These results are based in part on calculations made using simple one-dimensional ocean models. We recalculate the ocean inventory of bomb (super 14) C using a three-dimensional ocean general circulation model, and find a significantly smaller inventory after about 1980 than in previous one-dimensional model estimates. Our new estimate of the ocean inventory implies that the apparent imbalance in the global budget of bomb (super 14) C is smaller than previously thought and is not significantly different from zero.

The isotopic composition was determined of water-soluble Cl extracted from mineral grains in the sampled granite bedrock, boulders shielded from direct exposure to cosmic rays, and from inselbergs. The resulting (super 36) Cl/Cl analyses reflect the relative rates of erosion: outcrops of saprolite have model erosion rates higher than most bedrock surfaces. Erosion rates appear to be spatially consistent. Some granitic landforms are stable eroding on the order of m to tens of m/m.y. Samples from debris-flow fan surfaces of three separate ages show the expected increase in model age with time, but the (super 36) Cl-exposure ages for boulders on any surface vary by a factor of five.

Large variations in La, Cr, Sr and Fe in the bulk samples indicate inhomogeneous distribution of the host minerals, whereas Mn, Sc and Na are uniformly distributed reflecting constant fractions of olivine, orthopyroxene and plagioclase. There is an equilibrium distribution of heavy REE and non-equilibrium for light REE. A fluid phase rich in incompatible elements infiltrated the meteorite and REE and U were extracted by phosphates. The parent body had a complex evolution with a thermal history different from that of ordinary chondrite parent bodies (OC); the former accreted earlier than the latter so that more (super 26) Al was available for heating leading to higher peak T than in OC. Extensive solid-state equilibrium at 900 degrees C erased the (super 26) Mg signature in plagioclase.

When these seismograms are carefully converted to ground displacement, there appears to be a static offset which is on order of 2 cm. We have modeled the waveforms with a synthetic waveform method that contains near-, intermediate- and far-field terms. Although the synthetics are only calculated for an elastic half-space, they compare favorably with the observed waveform in terms of shape. However, the theoretical amplitude is 1/2 of the observed static offset, which probably reflects the limitations of a homogeneous halfspace model and/or the instabilities in deconvolution.

This is the largest deep event in recorded history and ruptured a portion of the down-going Nazca slab unknown to have ruptured previously. We recorded the main shock and aftershocks on the BANJO and SEDA portable, broadband seismic arrays deployed in Bolivia during this event. Myers et al. (this issue) identified and located 36 aftershocks (M>2) for the 10-day period following the main shock. We use a grid search technique to determine focal mechanisms for 12 of these aftershocks ranging in magnitude from 2.7 to 5.3. We compare the observed P to SV and SH ratios to a series of synthetics that represent different fault plane orientations. We find consistent focal mechanisms with the T-axis roughly horizontal and oriented approximately east-west, and the P-axis predominantly vertical. The aftershock focal mechanisms indicate a rotation of the P-axis within the slab from down-dip compression prior to the main shock to a near-vertical direction afterwards. This observation is consistent with the release of shear stress on the near-horizontal rupture plane and the subsequent rotation of the maximum compressive stress to a fault -normal orientation.

The mainshock and aftershocks were recorded in Bolivia on the BANJO and SEDA broadband seismic arrays and on the San Calixto Network. We used the joint hypocenter determination method to determine the relative location of the aftershocks. We have identified no foreshocks and 89 aftershocks (m > 2.2) for the 20-day period following the mainshock. The frequency of aftershock occurrence decreased rapidly, with only one or two aftershocks per day occuring after day two. The temporal decay of aftershock activity is similar to shallow aftershock sequences, but the number of aftershocks is two orders of magnitude less. Additionally, a m (sub b) approximately 6, apparently triggered earthquake occurred just 10 minutes after the mainshock about 330 km east-southeast of the mainshock at a depth of 671 km. The aftershock sequence occurred north and east of the mainshock and extends to a depth of 665 km. The aftershocks define a slab striking N68 degrees W and dipping 45 degrees NE. The strike, dip, and location of the aftershock zone are consistent with this seismicity being confined within the downward extension of the subducted Nazca plate. The location and orientation of the aftershock sequence indicate that the subducted Nazca plate bends between the NNW striking zone of deep seismicity in western Brazil and the N-S striking zone of seismicity in central Bolivia. A tear in the deep slab is not necessitated by the data. A subset of the aftershock hypocenters cluster along a subhorizontal plane near the depth of the mainshock, favoring a horizontal fault plane. The horizontal dimensions of the mainshock [Beck et al., this issue; Silver et al., 1995] and slab defined by the aftershocks are approximately equal, indicating that the mainshock ruptured through the slab.

The atomic ratio of (super 26) Al/ (super 10) Be in surface ocean is close to 1X10 (super -4) , at least an order lower than the atmospheric production ratio. Surface-ocean particulate removal of Al is about 30 times more rapid than that of Be. The results of this first set of data on (super 26) Al in seawater also suggest that the source of (super 26) Al in the sea is dominated by spallation of Ar in the atmosphere (as opposed to eolian and cosmic-dust inputs) and that the ratio (super 26) Al/ (super 10) Be in marine sediments can be potentially used to decipher past variations of oceanic particle flux, hence biologic productivity.

It is shown how these partitioning data can be used to discern important trace element differences between melts and fluids equilibrated with sources of the same composition. The data show the unique role of rutile in suppressing the flux of HFSE relative to LILE to the mantle wedge, accounting in turn for the distinct HFSE depletions in island-arc basalts. A first-order assessment is made of the quantities of certain trace elements that may be recycled into the mantle following slab dehydration, confirming that some of the unique isotopic characteristics of OIB sources are consistent with the presence of subducted materials.

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.

Many of the older tufas (>21,000 yr B.P.) contained in the mounds were formed in association with ground-water discharge. The radiocarbon ( (super 14) C) ages of the older tufas represent maximum estimates of the time of their formation. Lake Lahontan experienced large and abrupt rises in level at approximately 22,000, 15,000, and 11,000 yr B.P. and three abrupt recessions in level at approximately 16,000, 13,600, and 10,000 yr B.P. The lake-level rises that were initiated at approximately 23,500 and 15,500 yr B.P. are believed to indicate the passage of the polar jet stream over the Lahontan basin. During expansion of the Laurentide Ice Sheet, the jet stream moved south across the basin, and during the contraction of the Ice Sheet, the jet stream moved north across the basin. The bulk of the carbonate contained in the mound tufas was deposited during the last major lake cycle ( approximately 23,500-12,000 yr B.P.), indicating that ground- and surface-water discharges increased at approximately 23,500 and decreased at approximately 12,000 yr B.P. A lake-level oscillation that occurred between 11,000 and 10,000 yr B.P. is represented by a 2-cm thick layer of dense laminated tufa that occurs at and below 1180 m in the low-elevation tufa mounds and at 1205 m in the Winnemucca Lake subbasin.

AN - 77371249; 7603995 AB - The mutagen-sensitive CHO line irs1SF was previously isolated on the basis of hypersensitivity to ionizing radiation and was found to be chromosomally unstable as well as cross-sensitive to diverse kinds of DNA-damaging agents. The analysis of somatic cell hybrids formed between irs1SF and human lymphocytes implicated a human gene (defined as XRCC3; x-ray repair cross-complementing), which partially restored mitomycin C resistance to the mutant. A functional cDNA that confers mitomycin C resistance was transferred to irs1SF cells by transforming them with an expression cDNA library and obtaining primary and secondary transformants. Functional cDNA clones were recovered from a cosmid library prepared from a secondary transformant. Transformants also showed partial correction of sensitivity to cisplatin and gamma-rays, efficient correction of chromosomal instability, and substantially improved plating efficiency and growth rate. The XRCC3 cDNA insert is approximately 2.5 kb and detects an approximately 3.0-kb mRNA on Northern blots. The cDNA was mapped by fluorescence in situ hybridization to human chromosome 14q32.3, which was consistent with the chromosome concordance data of two independent hybrid clone panels.

AN - 77618682; 7548748 AB - The food mutagen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) forms adducts to DNA guanine bases at the C-8 position. No other DNA adduction site has been verified for PhIP, nor has any experimental data been collected on the conformation of the PhIP-DNA covalent complex. To determine if multiple PhIP-DNA adduct species exist, or if PhIP-DNA adducts assume multiple conformations, 2-(acetoxyamino)-1-methyl-6-phenylimidazo[4,5-b]-pyridine (N-acetoxy-PhIP) was reacted with calf thymus DNA, followed by an evaluation of the resulting adduct complexes by fluorescence spectroscopy. Approximately 20% of the N-acetoxy-PhIP formed covalent complexes with DNA. Two major and several minor spots were observed by 32P-postlabeling, suggesting a minimum of two major adduct species. UV/vis spectra of the PhIP-modified DNA also showed heterogeneous formation of PhIP-DNA adducts. Fluorescence excitation and emission spectroscopy with or without fluorescence quenching (silver ion and acrylamide) was used to evaluate the number of adducts formed, and the low-resolution conformation of each adduct. Four adduct fluorophores were observed and assigned the nomenclature PAi, where "PA" denotes PhIP Adduct and i = 1-4 in order of fluorescence emission band energies, with 1 the highest and 4 the lowest energy, respectively. Excitation maxima for the adduct fluorophores ranged from 340 to 370 nm, and emission maxima ranged from 390 to 420 nm. The fluorescence from adduct PA1 was quenched by silver but not acrylamide, suggesting a helix-internal configuration. Adduct PA2 fluorescence was strongly enhanced upon silver binding but was not affected by acrylamide, also indicating that this adduct was internal. The fluorescence from adducts PA3 and PA4 was quenched by acrylamide but not silver; thus PA2 and PA3 were tentatively assigned as solvent-accessible.

AN - 77428868; 7628789 AB - Heterocyclic aromatic amines are sometimes formed during the cooking of muscle meats, and their mutagenic and carcinogenic effects are of potential concern in the aetiology of human cancer. In a large survey of the heterocyclic amine content of foods, fried or charbroiled hamburgers, fried chicken, chicken breast sandwiches, fish sandwiches and breakfast sausages were purchased from fast-food restaurants. At least three different chains were visited per product and samples from five stores from each chain were pooled. The solid-phase extraction and HPLC method was used to analyse pooled samples for heterocyclic amine content and mutagenic activity with the Ames/Salmonella assay. Samples were analysed in a blind study which also contained quality control samples of two types, one high and one low in heterocyclic amine content and mutagenic activity. Results from the fast-food products showed undetectable levels of heterocyclic amines in 10 of 17 samples and only low levels [< or = 1 ng/g total of 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx)] in the remaining samples. Compared with literature values based primarily on laboratory and home cooking conditions, fast-food meat products appear to contribute only a small percentage of the estimated daily dietary intake of heterocyclic amines.

The heat-exchange system at the facility used trichloroethene TCE as the primary heat-transfer media for over 20 years. Accidental spills, pipe failures, and seal blowouts over that period contributed to a substantial contaminant plume in a perched water-bearing zone underlying the Complex. Individual wells near the source area have produced ground water samples with TCE concentrations exceeding 800,000 ppb. In the last several years, the authors have developed a modular ground water and soil vapor extraction system for remediating the plume source area. The modular facility design permits the testing of new technologies to expedite remediation, and/or reduce the quantity of hazardous wastes generated as by-products of the primary remedial activities. To contain costs, the authors have used equipment and components recycled from the original Building 834 Complex heat-exchange system, and surplus equipment from other LLNL divisions. The authors have executed two large-scale tests of energy injection systems for TCE destruction in air (a free-air electron beam and a pulsed, ultraviolet photolysis system), and a soil heating test for accelerating vapor extraction. New work plans for this unique site are being prepared, incorporating the lessons learned in developing new technology with recycled equipment.

AN - 85165238; pmid-7790647 AB - People with serious heart conditions have had their expected life span extended considerably with the development of the prosthetic heart valve especially with the great strides made in valve design. Even though the designs are extremely reliable, the valves are mechanical and operating continuously over a long period; therefore structural failures can occur due to fatigue. In this paper acoustical signal processing techniques developed to process noisy heart valve sounds measured by a sensitive, surface contact microphone are discussed. Measuring heart sounds noninvasively in a noisy environment puts more demands on the signal processing to extract the desired signals from the noise. Heart valve sounds are short-duration (10-20 ms) transients and therefore nonstationary, requiring more sophisticated processing algorithms to achieve the desired signal-to-noise ratios. In this paper the preclassification signal processing is concentrated on exclusively. That is, the signal processing operations performed on the heart valve sounds prior to classification are discussed--a subject that will be developed in a future paper. Efforts are concentrated on the sounds corresponding to the heart valve opening cycle. Valve opening and closing acoustics present additional information about the outlet strut condition--the structural component implicated in valve failure. The importance of the opening sound for single leg separation detection/classification is based on the fact that as the valve opens, the disk passively hits the outlet strut. The opening sounds thus yield direct information about outlet strut condition with minimal amount of disturbance caused by the energy radiated from the disk. Hence the opening sound is a very desirable acoustic signal to extract. Unfortunately, the opening sounds have much lower signal levels relative to the closing sounds and therefore noise plays a more significant role than during the closing event. Because of this it is necessary to screen the sounds for outliers in order to insure a high sensitivity of classification. Because of the sharp resonances appearing in the corresponding spectrum, a parametric processing approach is developed based on an autoregressive model which was selected to characterize the sounds emitted by the Bjork-Shiley convexo-concave (BSCC) valve during opening cycle. First the basic signals and the extraction process used to create an ensemble of heart valve sounds are briefly discussed. Next, a beat monitor capable of rejecting beats that fail to meet an acceptance criteria based on their spectral content is developed.(ABSTRACT TRUNCATED AT 400 WORDS) JF - The Journal of the Acoustical Society of America AU - Candy, J V AU - Jones, H E AD - University of California, Lawrence Livermore National Laboratory 94550, USA.

AN - 85159254; pmid-7790648 AB - People with heart problems have had their lives extended considerably with the development of the prosthetic heart valve. Great strides have been made in the development of the valves through the use of improved materials as well as efficient mechanical designs. However, since the valves operate continuously over a long period, structural failures can occur--even though they are relatively uncommon. Here the development of techniques to classify the valve either as having intact struts or as having a separated strut, commonly called single leg separation, is discussed. In this paper the signal processing techniques employed to extract the required signals/parameters are briefly reviewed and then it is shown how they can be used to simulate a synthetic heart valve database for eventual Monte Carlo testing. Next, the optimal classifier is developed under assumed conditions and its performance is compared to that of an adaptive-type classifier implemented with a probabilistic neural network. Finally, the adaptive classifier is applied to a data set and its performance is analyzed. Based on synthetic data it is shown that excellent performance of the classifiers can be achieved implying a potentially robust solution to this classification problem.

AN - 77301825; 7759253 AB - Chromosome painting was employed to measure frequencies of reciprocal translocations in human lymphocytes induced by 60Co gamma rays, with emphasis on low doses. Translocations and dicentrics were distinguished by use of a pan-centromeric probe. A total of 41,151 metaphases were analyzed at doses below 0.2 Gy. The linear "take-off" slope of the linear-quadratic dose-response curve for translocations, i.e., the alpha coefficient, was measured to be 0.023 +/- 0.005 translocations per cell per Gy. This alpha coefficient is more precise than previously measured. Because the alpha coefficient is the dominant contributor to the translocation frequency induced by low-level exposures, the results presented here will substantially reduce uncertainties in biodosimetry estimates obtained for stable translocations.

The stress state changes in considerable domains of massif create dangerous concentration of stresses at large geological heterogeneities, faults localized in the mining works zone. The purpose of the present work is to study the engineering activity influence to processes occurring in the upper part of Earth crust and in particular in a rock massif. The rock massif is treated in those studies as a geophysical medium - such approach takes into account the presence of block structure of medium and the continuous exchange of energy between parts of that structure. The idea "geophysical medium" is applied in geophysics sufficiently wide and stresses the difference of actual Earth crust and rock massifs from the continuous media models discussed in mechanics.

This work was carried out in the Complex Seismological Expedition (CSE) of the Joint Institute of Physics of the Earth of the Russian Academy of Sciences and Lawrence Livermore National Laboratory. The recording system, methods of investigations and primary data processing are described in detail. The largest number of digital records was received by the permanent seismic station Talgar, situated in the northern Tien Shan, 20 km to the east of Almaty city. More than half of the records are seismograms of underground nuclear explosions and chemical explosions. The nuclear explosions were recorded mainly from the Semipalatinsk test site. In addition, records of the explosions from the Chinese test site Lop Nor and industrial nuclear explosions from the West Siberia region were obtained. Four records of strong chemical explosions were picked out (two of them have been produced at the Semipalatinsk test site and two in Uzbekistan). We also obtained 16 records of crustal earthquakes, mainly from the Altai region, close to the Semipalatinsk test site, and also from the West China region, close to the Lop Nor test site. In addition, a small number of records of earthquakes and underground nuclear explosions, received by arrays of temporary stations, that have been working in the southern Kazakhstan region are included in this report. Parameters of the digital seismograms and file structure are described. Possible directions of future work on the digitizing of unique data archive are discussed.

Cr-bearing cast irons are resistant to chloride environments and solutions containing strongly oxidizing constituents. Weathering steels, including high content and at least 0.04% Cu, appear to provide adequate resistance to oxidation under temperate conditions. However, data from long-term, high-temperature oxidation studies on weathering steels were not available. From the literature, it appears that the low alloy steels, plain carbon steels, cast steels, and cast irons corrode at similar rates in an aqueous environment. Alloys containing more than 12% Cr or 36% Ni corrode at a lower rate than plain carbon steels, but pitting may be worse. Short term tests indicate that an alloy of 9Cr-1Mo may result in increased corrosion resistance, however long term data are not available. Austenitic cast irons show the best corrosion resistance. A ranking of total corrosion performance of the materials from most corrosion resistant to least corrosion resistant is: Austenitic Cast Iron; 12% Cr = 36% Ni = 9Cr-1Mo; Carbon Steel = Low Alloy Steels; and Cast Iron. Since the materials to be employed in the Advanced Conceptual Design (ACD) waste package are considered to be corrosion allowance materials, the austenitic cast irons, high Cr steels, high Ni steels and the high Cr-Mo steels should not be considered as candidates for the outer containment barrier. Based upon the oxidation and corrosion data available for carbon steels, low alloy steels, and cast irons, a suitable list of candidate materials for a corrosion allowance outer barrier for an ACD waste package could include, A516, 2.25%Cr -- 1%Mo Steel, and A27.

The radiologic source term also includes potentially mobile short-lived radionuclides excluded from the inventory. The radiologic source term for tritium is known with accuracy and is equivalent to the hydrologic source term within the saturated zone. Definition of the total hydrologic source term for fission and activation products that have high activities for decades following underground testing involves knowledge and assumptions which are presently unavailable. Systematic investigation of the behavior of fission products, activation products and actinides under saturated or Partially saturated conditions is imperative to define a representative total hydrologic source term. This is particularly important given the heterogeneous distribution of radionuclides within testing centers. Data quality objectives which emphasize a combination of measurements and credible estimates of the hydrologic source term are a priority for near-field investigations at the Nevada Test Site.

This research is carried out under the Comprehensive Test Ban Treaty Research and Development Program (CTBTR and D) under task S4.3.4. For regions where the path is calibrated, this modeling can potentially identify and discriminate between clandestine underground nuclear events and other sources of seismic waves such as earthquakes and mine collapses. In regions where the path is not calibrated but is seismically active, the author is investigating the use of moderate to large earthquakes to obtain the necessary path calibration. Research has focused on improving whole waveform techniques for determining the source mechanism of moderate (magnitude greater than about 3.5) seismic events from a few three-component broadband sensors in regions where the paths are calibrated. Presently the author is also using these waveform techniques in new regions to test and improve path calibrations as well as to identify events. As part of this work, he has applied these waveform techniques to events of high monitoring interest with excellent results. In this report he discusses fitting three main types of events, explosions, earthquakes and mine collapses.

This behavior is unlike that exhibited by other Yukon-Tanana samples or by most rocks from other locations. Detailed petrographic examination of the sample revealed the presence of a stringer of carbonaceous material generally less than 10 mu m thick enclosed in and intergrown with one of the muscovite layers and extending for about 2 cm along the foliation. The stringer is probably responsible for the anomalous conductivity change with pressure, making the sample the first for which anomalous electrical conductivity behavior can be attributed to carbon associated with a specific feature. The carbonaceous stringer together with its host muscovite layer are deformed and broken around a rotated garnet porphyroclast. The deformation was accommodated by plastic deformation of quartz and therefore occurred in the ductile regime under conditions at least equivalent to greenschist facies metamorphism. We interpret the textural relations to indicate that the carbonaceous material was formed by fluid deposition in a fracture formed within the muscovite layer, possibly during the main phase of metamorphism and deformation, and that the mica and carbon stringer were then deformed by the noncoaxial deformation responsible for rotation of the garnet porphyroclasts. Together the facts that the deformation resulting in garnet rotation was ductile and that the garnet rotation disrupted the stringer demonstrate that the carbonaceous stringer was present at depth (i.e., > 10 km). Brittle deformation on the microscopic scale is observed to have broken the connectivity of the carbon stringer, explaining in part why the rock does not exhibit anomalously high conductivity at 0.1 MPa (1 atm) pressure. The brittle deformation is interpreted to have been caused by unloading due to uplift. The observations indicate that carbonaceous material may exert a primary control on crustal electrical conductivity because it may be present as interconnected arrays in grain boundaries or microfractures or in megascopic, throughgoing fractures.

Although induction logs are widely used to obtain the conductivity near boreholes, the poor resolution offered by surface-based electrical and electromagnetic (EM) field systems has thus far limited obtaining this information in the region between boreholes. Low-frequency crosswell EM offers the promise of providing subsurface conductivity information at a much higher resolution than was previously possible. Researchers at Lawrence Livermore National Lab (LLNL) and Lawrence Berkeley Laboratories (LBL), together with an industrial consortium, recently began a program to conduct low-frequency crosswell EM surveys and develop suitable inversion techniques for interpreting the data.In developing the field instrumentation we used off-the-shelf components whenever possible, but custom-designed induction coil transmitters and receivers were built for the field experiments. The assembled field system has adequate power for moderate to high-resolution imaging, using boreholes spaced up to 500 m apart. The initial field experiment was undertaken in flat lying terrain at the British Petroleum test site in Devine, Texas. Using wells spaced 100 m apart, we collected a complete crosswell EM data set encompassing a 30 m thick, 10 ohm-m limestone layer at a depth of 600 m. The resulting profiles were repeatable to within 1% and showed an excellent sensitivity to the layered structure, closely matching the borehole induction resisitivity log. At the UC Richmond field station, crosswell EM measurements were made to track an injected slug of salt water. Conductivity images of data collected before and after injection showed a clear anomaly as a result of the salt water plume and indicated that the plume had migrated in a northerly direction from the injection borehole.

AN - 77301018; 7767987 AB - We investigated the specific sequence changes produced by the dietary mutagen 2-amino-1-methyl-6-phenylimidazo-[4,5-b]pyridine (PhIP) in UV5P3 cells [a Chinese hamster ovary (CHO) cell line]. Sequence analysis of the PhIP-induced mutations in the adenine phosphoribosyltransferase (aprt) gene, which is heterozygous in the UV5P3 cells, can provide insight into the mutagenic mechanism in these repair-deficient cells expressing P4501A2. Two allele-specific 20 mer oligonucleotide primer pairs were used in the polymerase chain reaction and the allele of interest was amplified. Single-base transversions occurred in 31/32 PhIP-induced mutants; of these, 6 were A.T-->T.A, 18 were C.G-->A.T and 6 were G.C-->T.A. Twenty of the 30 changes altered specific amino acid sequences and the other 10 resulted in a stop codon. On mutant had a change from C.G-->G.C at the 3' splice site of intron 4, thereby creating a new AG splice acceptor site. Another mutant had an insertion of T within a run of repeated sequences and resulted in a frameshift mutation. There were three 'hot-spots', two at the 3' end of exon 2 and one at the beginning of exon 3; 6 (19%) mutants showed a change from A.T-->T.A (exon 2, amino acid residue 57), 11 (34%) mutants from C.G-->A.T (exon 2, amino acid residue 62), and 7 (22%) mutants from C.G-->A.T (exon 3, amino acid residue 66). Consequently, 75% of the mutations were observed at these three sites. In contrast, none of the 20 spontaneous mutants had alterations at these hotspot sites. The mutations induced by PhIP in these repair-deficient CHO cells were unique and specific, and suggest that these sequences, if found in important genes controlling cell replication and survival, may be more susceptible to mutation from these food mutagens than genes not containing these sequences.

AN - 77253194; 7739600 AB - Four ENU-induced mutations were previously identified at the triosephosphate isomerase (TPI) locus in mouse germinal mutation experiments. Each of the mutants is associated with a 50% loss of enzymatic activity in the F1 (heterozygous) animals. Exons of the TPI gene from control mice and heterozygous mutant mice were PCR amplified and sequenced as necessary to determine the molecular lesion in the mutant alleles. Mutants Tpi*M-1NEU and Tpi*M-2NEU carried the same T:A to A:T transversion in exon 6, resulting in a Leu to Gln substitution at residue 192. Amino acid residue 192 is located in alpha-helix H6 of the protein. Tpi*M-4NEU contained a T:A to A:T transversion within the codon for residue 162 in exon 5, also causing a Leu to Gln substitution. This mutation is located at the beginning of beta-strand B6, within a highly conserved sequence region surrounding the active site residue Glu 165. Sequence analysis of Tpi*M-3NEU revealed an A:T to C:G transversion, changing the stop codon to a codon for Cys, with the resulting addition of 19 predominantly hydrophobic amino acids to the protein. All four mutations occurred at an A:T base pair. In each case, the mutation site was flanked on both sides by G:C base pairs. Each of the sequence alterations has a potential impact on the structure of the TPI protein that is consistent with the existence of a null allele. In addition to providing insight into the molecular basis of ENU induced germ cell mutations and the differences in mutation spectra among organisms, these mutants represent models for structure-function studies of this highly conserved enzyme.

This evaluation requires knowledge about what radioactive materials are in the groundwater and how they are transported through the underground environment. This information coupled with models of groundwater flow (flow paths and flow rates) will enable predictions of the arrival of each radionuclide at a selected receptor site. Risk assessment models will then be used to calculate the expected environmental and human doses. The accuracy of our predictions depends on the validity of our hydrologic and risk assessment models and on the quality of the data for radionuclide concentrations in ground water at each underground nuclear test site. This paper summarizes what we currently know about radioactive material in NTS groundwater and suggests how we can best use our limited knowledge to proceed with initial modeling efforts. The amount of a radionuclide available for transport in groundwater at the site of an underground nuclear test is called the hydrologic source term. The radiologic source term is the total amount of residual radionuclides remaining after an underground nuclear test. The hydrologic source term is smaller than the radiologic source term because some or most of the radionuclide residual cannot be transported by groundwater. The radiologic source term has been determined for each of the underground nuclear tests fired at the NTS; however, the hydrologic source term has been estimated from measurements at only a few sites.

The results represent a new technological application using isotope hydrology to better understand and predict the sustainability of California's groundwater supply for the future. This project is driven by the fact that Californians inhabit a semi-arid region of seasonal precipitation, but have created a lifestyle and economic infrastructure requiring a sub-tropical climate. They have accomplished this by engineering systems that store and divert alpine runoff and by utilizing a large, productive alluvial aquifer. In the past, both of these resources appeared to be unlimited. Today, water shortages are recognized, regardless of drought conditions. Because Californians maintain their current practices of prolific water use, the deep-seated competition between agricultural users and urban consumers has been amplified. This has been aggravated by the acquisition of one-third of the available surface water resources for maintenance of aquatic habitats. The State of California accepts and encourages the use of groundwater to supplement these diverse water demands. Stable isotope imaging of the groundwater resources has proven to be the most economical and effective means to diagnose the health of the giant alluvial aquifer of the Central Valley. Augmented by radiocarbon analysis and nitrate determinations, stable isotope data can be used to clearly distinguish groundwater recharged from natural or anthropogenic sources. Isotope maps delineate (1) the geographic distribution of various groundwater masses and of preferential recharge zones, (2) the sources and extent of non-point source pollution, and (3) the locations and rates of lateral flow channels. Different recharge rates of natural and modem groundwater bodies can be used to characterize safe yield parameters for aquifers.

Currently, the threshold sensitivity of our system is approximately 100 mD, making possible the characterization of typical petroleum reservoir rocks with spatial resolution of between 0.5 and 5 mm in the 50 kHz to 500 kHz frequency range. The degree of disorder in permeable solids is of crucial importance especially when the relative permeability is considered. It is expected that this new technique can complement such methods as hydrodynamic dispersion measurements and petrography for characterizing flow in porous rocks.

AN - 1529925193; 19556318 AB - Our calculations indicate that regions above large mesoscale convective systems may be favorable electrical environments for the production of gamma radiation by runaway electrons in bremsstrahlung collisions. It is well known [Gurevich, 1961] that an electric field however small can accelerate an electron continuously until the electron leaves the region of the electric field, as long as the electric field is larger than the opposing force of friction. Since the force of friction is proportional to the density of air, the resistance on an electron decreases with altitude. The resistance can be expressed in terms of a critical field, which is the strength the field needs to exceed in order to initiate the runaway phenomena. The critical field characterizing the friction is between 710 super(-15) and 1510 super(-15) V-cm super(2) times the number density of air. Thus a reasonable electric field (500 V/m) at high altitudes results in a force that can be larger than the force of friction. The rate for producing high energy electrons by the electric fields over large thunderstorms is estimated from Gurevich's model of runaway electrons in a weakly ionized plasma. It is found that the number of gamma photons produced by the runaway electrons in the discharge volume is consistent with the data recently observed by satellite [Fishman et al., 1994].

AN - 77383692; 7607692 AB - The V79 hamster cell line irs1 is a repair-deficient mutant hypersensitive to radiation and DNA-reactive chemical agents. Somatic cell hybrids were formed by fusing irs1 cells with human lymphocytes and selecting for complementation in medium containing concentrations of mitomycin C (MMC) that are toxic to irs1. Thirty-eight MMC-resistant hybrids showed extensive segregation of human chromosomes, with 35 of them retaining human chromosome 7, as indicated by molecular marker and cytogenetic analyses. Inter-Alu-PCR products from the DNA of hybrids, when used as fluorescence in situ hybridization probe onto normal human metaphases, indicated that one resistant hybrid was monochromosomal for chromosome 7 and that the three resistant hybrids shown to be negative for chromosome 7 markers have retained portions of chromosome 7, with region 7q36 being the smallest common region. MMC-sensitive subclones of a resistant hybrid lost human chromosome 7. Therefore, the gene complementing the repair defect, XRCC2 (X-ray repair cross complementing), is assigned to human chromosome 7q36.

They involved the cell attachment to site-specific sediments, the intrinsic resting-cell biotransformation capacities for the contaminants of interest plus their time-dependent extents of biodegradative removal at the concentrations of concern, and a scaled in situ mini-flow-through-column system that closely mimics the subsurface conditions during a field-treatability or pilot test of an emplaced resting-cell filter. These experiments established the conditions required for the complete metabolic removal of a vinyl chloride (VC), cis-dichlororthylene (cis-DCE) and trichloroethylene (TCE) mixture. However, the gas chromatographic (GC) procedures that we utilized and the mini-flow-through column data demonstrated that, at most, only about 50-70% of the site-water VC, cis-DCE, and TCE would be biodegraded. This occurred because of a limiting level of dissolved oxygen, which was exacerbated by the simultaneous presence of several additional previously unrecognized groundwater components, especially methane, that are also competing substrates for the whole-cell soluble methane monooxygenase (sMMO) enzyme complex.

Current leak detection methods for single shell tanks require careful inventory monitoring, usually from liquid level sensors within the tank, or placement of chemical sensors in the soil under and around the tank. Liquid level sensors can signal a leak but are limited in sensitivity and, of course, give no information about the location or the leak or the distribution of the resulting plume. External sensors are expensive to retrofit and must be very densely spaced to assure reliable detection, especially in heterogeneous soils. The rational for using subsurface tomography is that it may not have any of these shortcomings.

Experiments performed include an initial column experiment for VOC (TCE and perchloroethylene (PCE)) retardation tests on geological materials, PCE and TCE data from LLNL sediments, and a preliminary multilayer sampler experiment. The VOC K (sub d) s in low organic carbon permeable aquifer materials are dependent on the VOC composition and independent of aquifer grain size, indicating that sorption was not operative and that the primary retarding factors are diffusion controlled. The program of future experiments is described.

Years of groundwater pumping may not completely remove the contamination. Researchers at Lawrence Livermore National Laboratory (LLNL) and the College of Engineering at the University of California at Berkeley (UCB) have collaborated to develop a technique called Dynamic Underground Stripping to remove localized underground spills in a relatively short time. The U.S. Department of Energy's Office of Environmental Restoration and Waste Management has sponsored a full-scale demonstration of this technique at the LLNL gasoline spill site. When highly concentrated contamination is found above the standing water table, vacuum extraction has been very effective at both removing the contaminant and enhancing biological remediation through the addition of oxygen. Below the water table, however, these advantages cannot be obtained. For such sites where the contamination is too deep for excavation, there are currently no widely applicable cleanup methods. Dynamic Underground Stripping removes separate-phase organic contaminants below the water table by heating the subsurface above the boiling point of water, and then removing both contaminant and water by vacuum extraction. The high temperatures both convert the organic to vapor and enhance other removal paths by increasing diffusion and eliminating sorption. Because this method uses rapid, high-energy techniques in cleaning the soil, it requires an integrated system of underground monitoring and imaging methods to control and evaluate the process in real time.

We have obtained a direct estimate of the present-day atmospheric CO (sub 2) flux from convective hydrothermal systems within subaerial, seismically-active, high heat flow regions. Geothermal systems of the Salton Trough (California, U.S.A.) and the Taupo Volcanic Zone (New Zealand) provide benchmarks for quantifying convective hydrothermal CO (sub 2) fluxes from such regions. CO (sub 2) fluxes from the Salton Trough ( approximately 10 (super 9) mol yr (super -1) ) and the Taupo Volcanic Zone ( approximately 8.10 (super 9) mol yr (super -1) ) were computed using data on convective heat flow and the temperatures and CO (sub 2) concentrations of reservoir fluids. The similarity in specific CO (sub 2) flux ( approximately 10 (super 6) mol km (super -2) yr (super -1) ) from these two disparate geologic/tectonic settings implies that this flux may be used as a baseline to compute convective hydrothermal CO (sub 2) emission from other areas of high heat flow. If this specific flux is integrated over high heat flow areas of the circum-Pacific and Tethyan belts, the total global CO (sub 2) flux could equal or exceed 10 (super 12) mol yr (super -1) . Adding this flux to a present-day volcanic CO (sub 2) flux of approximately 4.10 (super 12) mol yr (super -1) , the total present-day Earth degassing flux could balance the amount of CO (sub 2) consumed by chemical weathering ( approximately 7.10 (super 12) mol yr (super -1) ).

This work was designed to test the feasibility of injecting a weak mixture of methane in air as a metabolic carbon source for natural microbial populations which are capable of trichloroethylene degradation. Electrical resistance tomograms were constructed of the subsurface during the test to provide detailed images of the process. These images were made using an iterative reconstruction algorithm based on a finite element forward model and Newton-type least-squares minimization. Changes in the subsurface resistivity distribution were imaged by a pixel-by-pixel subtraction of images taken before and during the process. This differential tomography removed all static features of formation resistivity but clearly delineated dynamic features induced by remediation processes. The air-methane mixture was injected into the saturated zone and the intrained air migration paths were tomographically imaged by the increased resistivity of the path as air displaced formation water. We found the flow paths to be confined to a complex three-dimensional network of channels, some of which extended as far as 30 m from the injection well. These channels were not entirely stable over a period of months since new channels appeared to form with time. Also, the resistivity of the air injection paths increased with time. In another series of tests, resistivity images of water infiltration from the surface support similar conclusions about the preferential permeability paths in the vadose zone. In this case, the water infiltration front is confined to narrow channels which have a three-dimensional structure. Here, similar to air injection in the saturated zone, the water flow is controlled by local variations in formation permeability. However, temporal changes in these channels are minor, indicating that the permeable paths do not seem to be modified by continued infiltration.

The OGI facilities are unique; a double-wall tank 10 m square and 5 m deep, filled with river bottom sediments and instrumented for geophysical and hydrological studies. At this facility, liquid contaminants could be released into the confined soil at a scale sufficiently large to represent real-world physical phenomena. In the first test, images of electrical resistivity were made before and during a controlled spill of gasoline into a sandy soil. The primary purpose was to determine if electrical resistivity images could detect the hydrocarbon in either the vadose or saturated zone. Definite changes in electrical resistivity were observed in both the vadose and saturated soils. The effects were an increase in resistivity of as much as 10% above pre-release values. A single resistive anomaly was imaged, directly below the release point, principally within the vadose zone but extending below the phreatic surface. The anomaly remained identifiable in tomograms taken two days after the release ended with clear indications of lateral spreading along the water table. The second test involved electrical resistance measurements before, during, and after air sparging in a saturated soil. The primary purpose was to determine if the electrical images could be used to detect and delineate the extent of the zone influenced by sparging. The images showed an increase of about 20% in resistivity over background values within the sparged zone and the extent of the imaged zone agreed with that inferred from other information. Electrical resistivity tomography measurements were made under a simulated oil storage tank in the third test. Comparison of images taken before and during separate releases of brine and water showed effects of changes induced by the water or brine. The simulated leak and its location were imaged as a conductive anomaly centered near the point of origin and were observed to spread with time during the release.

AN - 77216395; 7714898 AB - Newly isolated members of two recently propagated (young) Alu subfamilies were examined for sequence diversity and insertion polymorphism in primate genomes. The smaller subfamily (termed HS-2) is comprised of approximately 5 to 25 members, while the larger (termed Sb2) includes approximately 125 to 600 members. Individual members of these Alu subfamilies share distinguishing sets of diagnostic mutations, are well-conserved relative to each other, and have expanded in the human lineage. At least one member from each subfamily is known to be polymorphic in humans. Three newly characterized HS-2 Alu family members as well as three Sb2 Alu repeats are monomorphic (fixed) in humans. The existence of a number of Alu subfamilies that have amplified in parallel within the human genome provides compelling evidence for the simultaneous activity of multiple dispersed Alu source genes.

The DOE has established policy and requirements for NPH mitigation for DOE sites and facilities using a graded approach by DOE Order 5480.28. The graded approach is implemented by five performance categories established for structures, systems, and components (SSCs) at DOE facilities based on criteria provided by DOE-STD-1021-93. In applying the design/evaluation criteria of DOE-STD-1020-94 for DOE facilities subjected to one of the natural phenomena hazards, the establishment of design basis load levels consistent with the corresponding performance category is required. This standard provides general criteria as well as specific criteria for natural phenomena hazard assessments to ensure that adequate design basis load levels are established for design and/or evaluation of DOE facilities.

The samples form continuous arrays on chemical and isotopic covariation diagrams and have similar coarse-granular textures and equilibration temperatures ( approximately 950 degrees -1050 degrees C). Sr and Nd isotopic compositions of acid-washed diopsides (epsilon (sub Nd) = +1.9 to +13.3; (super 87) Sr/ (super 86) Sr = 0.70220 to 0.70328) indicate long-term depletion of Rb relative to Sr and Nd relative to Sm, similar to asthenospheric (mid-ocean ridge basalt (MORB)) mantle. Lead isotopic compositions for all but one of the samples are generally higher in (super 206) Pb and (super 207) Pb, relative to (super 204) Pb, than is typical of MORB ( (super 206) Pb/ (super 204) Pb = 18.53 to 19.40; (super 207) pb/ (super 204) pb = 15 57 to 15<62). The peridotite suite as a whole is significantly depleted in both clinopyroxene and incompatible trace element concentrations (Sm/Nd = 0.5 to 0.8; [Nd] = 1.19-2.69 mu g/g). Isotopic and chemical systematics require that more than one depletion episode occurred in the history of the suite. Assuming that the La Olivina mantle had CHUR-like (chrondrite uniform reservoir) isotopic compositions prior to any of the depletion events, the initial event must have occurred at least approximately 735 Ma ago. The final depletion event could have occurred no more than approximately 280 Ma ago and involved a melt extraction of about 5-10% of the existing mass. Nd isotopic similarities between the peridotites and late Paleozoic arc-related basaltic rocks occurring in the Coahuila terrane to the southeast of La Olivina suggest that the final melting event may have produced this magmatism. The calculated magnitude of the presumed late Paleozoic melting and melt extraction implies that the La Olivina mantle was asthenospheric at that time. The peridotites contain veins of websterite that have resulted from mid-Cenozoic magmatic activity in the La Olivina region, indicating that the peridotites were in place and attached to the continent prior to the mid-Cenozoic. Increased buoyancy of the newly depleted asthenosphere coupled with a delamination of previously existing lithosphere, suggested by other studies, may have led to the accretion of the La Olivina mantle to the crust by the early Mesozoic (end of the Ouachita orogeny). Several La Olivina peridotites that have Sr-Nd isotopic compositions that indicate long-term depletion of incompatible elements have subsequently been enriched in these elements. These peridotites contain hydrous minerals and have rare earth element patterns that show enrichment of the light REE relative to the heavy REE. The Sr-Nd-Pb isotopic compositions of these samples indicate that the enriching agent contained isotopic components also present in the two episodes of Cenozoic magmatism in the La Olivina region. However, no satisfactory combination of agents directly related to the two magmatic events can account for the observed isotopic compositions of the enriched samples. This suggests that the enriching agent was not related to either of these magmatic episodes and that the isotopic components are not necessarily coupled together in the mantle regions producing the Cenozoic magmas.

Percolation behavior is a purely geometrical property, independent of any physical properties, and is a powerful constraint on any valid velocity-porosity relation. We show how the conventional Differential Effective Medium (DEM) theory can be modified to incorporate percolation of elastic moduli in rocks by taking the material at the critical porosity as one of the constituents of a two-phase composite. Any desired percolation porosity can be specified as an input. In contrast, the conventional DEM model always predicts percolation at a porosity of either 0 or 100 percent. Most sedimentary rocks however have intermediate percolation porosities and are therefore not well represented by the conventional theory. The modified DEM model incorporates percolation behavior, and at the same time is always consistent with the Hashin-Shtrikman bounds. The predictions compare favorably with laboratory sandstone data.

Seventy-six new estimates of crustal Sigma are reported covering all continents except Antarctica. On average Sigma increases with the age of the crust. This supports a mafic lower crust beneath cratons and uniformitarian craton formation with delamination of the lower crust during continental collisions followed by magmatic underplating, or alternatively crust formation processes that have changed since the Precambrian. In the last-named model, processes in young orogens are different from those active in the Precambrian. Young orogens involve recycling of existing continental crust with little crustal growth.
