We report on a search for the pair production of scalar leptoquarks, LQ, using 191 pb{sup -1} of proton-antiproton collision data recorded by the CDF experiment during Run II of the Tevatron. The leptoquarks are sought via their decay into a neutrino and quark yielding missing transverse energy and several jets of large transverse energy. No evidence for leptoquark production is observed, and limits are set on {sigma}(p{bar p} {yields} LQ{ovr OQ}X {yields} v{bar v}q{bar q}X). Using a next-to-leading order theoretical prediction of the cross section for scalar leptoquark production, we exclude first-generation leptoquarks in the mass interval 78 to 117 GeV/c{sup 2} at the 95% confidence level for BR(LQ {yields} vq) = 100%.

Field and laboratory investigations of naturally occurring CO{sub 2}-reservoirs are being conducted to determine the characteristics of potential seal and reservoir units and the extent of the interactions that occur between the host rocks and the CO{sub 2} charged fluids. Efforts have focused on the Farnham Dome field, located in central Utah, the Springerville-St. Johns field in Arizona and New Mexico, and most recently, the Crystal Geyser-Salt Wash graben areas with their CO{sub 2}-charged geysers and springs in central Utah. At both the Springerville-St. Johns field and the central Utah CO{sub 2} spring area, there is evidence of extensive travertine deposits that document release of CO{sub 2} to the atmosphere. At Farnham Dome, calcite debris fields appear to be remnants of vein calcite and an earlier period of fluid leakage. The main achievements during this quarter are (1): preparation for a soil gas flux survey in October at the Crystal Geyser --Little Grand Wash fault zone, and the Salt Wash graben; (2) submission of an abstract to the upcoming Measurement, Monitoring and Verification session at the Fall AGU meeting; (3) submission of an invited abstract to the Gordon Conference on Hydrocarbon Resources; and (4) receipt of initial radiocarbon dates of …

Certain shaped-charge cutting operations require a precision aiming system that is operationally convenient, robust, and constructed to allow the aiming system to be left in place for last-minute alignment verification until it is expended when the charge is fired. This report describes an aiming system made from low cost doubled-Nd:YAG 532 nm laser modules of the type used in green laser pointers. Drawings and detailed procedures for constructing the aiming system are provided, as are the results of some minimal tests performed on a prototype device.

The goal of this program is to develop a catalyst and a process for the conversion of syngas to isobutylene. However, due to the low conversion and selectivity generally experienced by the industry in direct conversion of syngas to isobutylene, indirect conversion via branched C{sub 4} alcohol intermediates is being explored. The objectives of the current program are to develop a catalyst and process for the conversion of syngas to isobutanol and to evaluate the commercial potential of the new process. The research program underway at UOP will identify and optimize key catalyst and process characteristics. This report covers the modification and shake-down of a fixed-bed pilot plant (No. 700) for the testing of catalysts and catalyst combinations. A separate syngas feed system has been added to an existing fixed bed Fischer-Tropsch pilot plant and new reactors are constructed to avoid catalyst cross contamination. Shake-down testing with a commercial Cu/Zn/Al oxide catalyst alone and in combination with a basic Mg/Al MOSS (Metal Oxide Solid Solution) catalyst have demonstrated good CO and H{sub 2} conversion. However, contamination of the product by residual Fischer-Tropsch product in the exit lines and the liquid gas chromatograph (GC) has prevented accurate product analyses. A separate …

This report itemizes the irradiations performed by Testing and Irradiation Services for Battelle-Northwest. It lists the materials being irradiated, awaiting disposition and materials shipped during the month of October 1967.

Abstract: "A number of direct current conduction type electromagnetic pumps for liquid metals were constructed. Pumping capacities of over 400 gpm and efficiencies of over 50 percent were obtained. NaK alloy at temperatures up to 400 C was used in the test. The large currents required were obtained from rectifiers or from a homopolar generator constructed for the purpose."

The data obtained from these tests determine the dose rate of the two cobalt sources in SRTC. This testing used chemical dosimetry to measure the dose rate of a radioactive source.

A discussion of the offsite effective dose equivalents reported for 1988 SRS releases serves as the basis for this report. Detailed analyses of atmospheric and liquid release trends and their consequences in terms of relative importance among facilities, radionuclides, and exposure pathways have also been included. Releases of radioactivity to the atmosphere were generally lower in 1988 than in 1987. No major unplanned tritium releases were recorded during the year. However, there were three inadvertent releases of Pu-238 from F Area in January, March and October of 160, 32 and 83 uCi, respectively. Radioactive releases to onsite streams from direct discharges and seepage basin migration decreased in 1988. However, as a result of a decrease in the flow rate of the Savannah River in 1988, higher offsite doses were reported. The maximum individual dose, conversely, was down from 1987. This decrease reflected the fact that the maximum individual dose is most significantly affected by the cesium concentration in fish. In terms of largest contributors to dose, the releases were dominated by tritium, Cs-137 and to a much lesser extent Sr-90. With respect to the offsite population, doses from atmospheric releases are generally higher than those from liquid releases, and this …

The Robert T. Stafford Disaster Relief and Emergency Assistance Act authorizes the President to declare that an emergency or major disaster exists that overwhelms state and local resources. Legislation before the 106th Congress (H.R. 707 and S. 1691) would, among other matters, amend the Act to: (1) fund hazard mitigation projects designed to reduce future disaster losses; (2) add conditions to assistance; and (3) consolidate provisions governing the distribution of aid to disaster victims. This report compares provisions of the two bills, and will be updated as legislative action occurs.

The dependence of the neutrino total cross section sigma /sub nu / on neutrino energy was measured up to 160 GeV. The data are consistent with a linear dependence with slope (0.58 plus or minus 0.25) x 10/sup -38/ cm/suup 2/ GeV. The ratio of the antineutrino to the neutrino total cross section sigma / sub nu / sigma /su b nu / was found to be approximately constant up to 70 GeV at a value which is consistent with the numerical value of 1/3 expected for the scattering of neutrinos and antineutrinos by relativistic pointlike spin 1/2 fermions.

One fundamental element of scientific inquiry is discoveringrelationships, particularly the interactions between different variablesin observed or simulated phenomena. Building upon our prior work in thefield of Query-Driven Visualization, where visual data analysisprocessing is focused on subsets of large data deemed to be"scientifically interesting," this new work focuses on a novel knowledgediscovery capability suitable for use with petascale class datasets. Itenables visual presentation of the presence or absence of relationships(correlations) between variables in data subsets produced by Query-Drivenmethodologies. This technique holds great potential for enablingknowledge discovery from large and complex datasets currently emergingfrom SciDAC and INCITE projects. It is sufficiently generally to beapplicable to any time of complex, time-varying, multivariate data fromstructured, unstructured or adaptive grids.

Recent methods for extracting precise measurements ofspatial gene expression patterns from three-dimensional (3D) image dataopens the way for new analysis of the complex gene regulatory networkscontrolling animal development. To support analysis of this novel andhighly complex data we developed PointCloudXplore (PCX), an integratedvisualization framework that supports dedicated multi-modal, physical andinformation visualization views along with algorithms to aid in analyzingthe relationships between gene expression levels. Using PCX, we helpedour science stakeholders to address many questions in 3D gene expressionresearch, e.g., to objectively define spatial pattern boundaries andtemporal profiles of genes and to analyze how mRNA patterns arecontrolled by their regulatory transcription factors.

One of the fundamental problems in remote visualization --where I/O and data intensive visualization activities take place at acentrally located supercomputer center and resulting imagery is deliveredto a remotely located user -- is reduced interactivity resulting from thecombination of high network latency and relatively low network bandwidth.This research project has produced a novel approach for latency-tolerantdelivery of visualization and rendering results where client-side framerate display performance is independent of source dataset size, imagesize, visualization technique or rendering complexity. As such, it is asuitable solution for remote visualization image delivery for anyvisualization or rendering application that can generate image frames inan ordered fashion. This new capability is suitable for use in addressingmany of ASCR s remote visualization needs, particularly deployment atopen computing facilities to provide remote visualization capabilities toteams of scientific researchers.
