Search for the top quark and other new particles at D0

Description: Preliminary results from the search for the top quark and other new particles in p[bar p] collisions at [radical]s = 1.8 TeV are reported. In a data sample corresponding to an integrated luminosity of about 7.5 pb[sup [minus]1], one candidate event for top quark is found in the di-lepton channel. A lower limit for the mass of the top quark of 103 GeV/c[sup 2] (99 Gev/c[sup 2]) is obtained at 95% confidence level with (without) background subtraction. Status of searches for other new particles t… more

Processing Constraints on High-Level Nuclear Waste Glasses for Hanford Waste Vitrification Plant

Description: The work presented in this paper is a part of a major technology program supported by the U.S. Department of Energy (DOE) in preparation for the planned operation of the Hanford Waste Vitrification Plant (HWVP). Because composition of Hanford waste varies greatly, processability is a major concern for successful vitrification. This paper briefly surveys general aspects of waste glass processability and then discusses their ramifications for specific examples of Hanford waste streams.

Formation of gas-phase peroxides in a rural atmosphere: An interpretation of the recent SOS/SERON field results

Description: Hydrogen perioxide (H{sub 2}O{sub 2}) and certain organic peroxides such as hydroxymethyl-hydroperoxide (HMHP), are gas-phase oxidants present in the atmosphere at ppbv concentration levels. These oxidants play an important role in atmospheric chemistry. In addition, precipitation containing H{sub 2}O{sub 2} is toxic to trees, and it has also been suggested that organic peroxides formed presumably by ozone reactions with biogenic alkenes are responsible for leaf disorders. Recently, we have dev… more

Possible differences in biological availability of isotopes of plutonium: Report of a workshop

Description: This paper presents the results of a workshop conducted on the apparent different bioavailability of isotopes {sup 238}Pu and {sup 239}Pu. There is a substantial body of evidence that {sup 238}Pu as commonly found in the environment is more biologically available than {sup 239}Pu. Studies of the Trinity Site, Nevada Test Site from nonnuclear and nuclear events, Rocky Flats, Enewetak and Bikini, and the arctic tundra support this conclusion and indicate that the bioavailability of {sup 238}Pu is… more

Energy-efficient mortgages and home energy rating systems: A report on the nation`s progress

Description: This report summarizes progress throughout the nation in establishing voluntary programs linking home energy rating systems (HERS) and energy-efficient mortgages (EEMs). These programs use methods for rating the energy efficiency of new and existing homes and predicting energy cost savings so lenders can factor in energy cost savings when underwriting mortgages. The programs also encourage lenders to finance cost-effective energy-efficiency improvements to existing homes with low-interest mortg… more

Cracking of textured zinc coating during forming process

Description: A model is presented to relate cracking of a zinc coating on steel during forming process with its crystallographic texture. There are three deformation modes that can accommodate strains in a zinc coating caused by external loadings; basal slip, twinning, and cleavage cracking. Twinning of a zinc hexagonal crystal induces a contraction along its c-axis while cleavage relaxes tensile strain along its c-axis. Because of this, when basal slip in grains of a textured zinc coating is difficult unde… more

Multiple-use marketing of lignite

Description: Marketing of lignite faces difficulties due to moisture and sulfur contents, as well as the sodium content, of the ash. The purpose of this study is to determine the economic viability of multiple-use marketing of lignite as a method to increase the use of North Dakota lignite by recapturing lost niche markets. Multiple-use marketing means using lignite and sulfur-capturing additives to clean agricultural wastewater followed by either direct steam and power generation or briquetting to produce … more

Microstructural development in irradiated vanadium alloys

Description: Three simple vanadium alloys, V-5Al, V-1Ni, and V-2Ti-1Ni have been examined to determine the effects of fast neutron irradiation on microstructural evolution. Specimens were irradiated in EBR II at temperatures in the range 425 to 600{degrees}C to doses of 15 and 31 dpa. Each alloy responded very differently to irradiation. All V-5Al specimens were generally void-free and contained high densities of coherent precipitates, and moderate densities of network dislocations. Swelling was much higher… more

High-level waste qualification: Managing uncertainty

Description: A vitrification facility is being developed by the U.S. Department of Energy (DOE) at the West Valley Demonstration Plant (WVDP) near Buffalo, New York, where approximately 300 canisters of high-level nuclear waste glass will be produced. To assure that the produced waste form is acceptable, uncertainty must be managed. Statistical issues arise due to sampling, waste variations, processing uncertainties, and analytical variations. This paper presents elements of a strategy to characterize and m… more

Three-dimensional effects for radio frequency antenna modeling

Description: Electromagnetic field calculations for radio frequency (rf) antennas in two dimensions (2-D) neglect finite antenna length effects as well as the feeders leading to the main current strap. Comparisons with experiments indicate that these 2-D calculations can overestimate the loading of the antenna and fail to give the correct reactive behavior. To study the validity of the 2-D approximation, the Multiple Antenna Implementation System (MAntIS) has been used to perform 3-D modeling of the power s… more

Boundary-layer cumulus over land: Some observations and conceptual models

Description: Starting in 1980, the Boundary Layer Research Team at the University of Wisconsin has been systematically studying the formation and evolution of nonprecipitating boundary-layer cumulus clouds (BLCu) in regions of fair weather (anticyclones) over land (Stull, 1980). Our approach is to quantify the average statistical characteristics of the surface, thermals, boundary layer, and clouds over horizontal regions of roughly 20 km in diameter. Within such a region over land, there is typically quite … more
