MetaBrowser: A combined browsing, query, and analysis tool
The MetaBrowser design is based on the premise that scientists should not be forced to learn new languages or commands for finding the data they are interested in and for selecting subsets of the data for further analysis. Furthermore, there should be a single system that permits browsing, query, and analysis of the data, so that the scientist does not have to switch between systems. The current version for the MetaBrowser was designed for the DOE CEDR (Comprehensive Epidemiological Data Resource) project, but the same principles can apply to other scientific disciplines. Browsing and query should be combined. It is quite natural for a user to explore the information in the database before deciding what subset of the data to select for further analysis. In general, if there is a large number of datasets (i.e. databases) in the system, then the user would want to find out information about the various datasets (called metadata), before choosing one or more datasets for further exploration. Thus, a metadatabase that holds information about datasets in the systems must exist.

Analysis of energy use in building services of the industrial sector in California: A literature review and a preliminary characterization
Energy use patterns in many of California's fastest-growing industries are not typical of those in the mix of industries elsewhere in the US. Many California firms operate small and medium-sized facilities, often in buildings used simultaneously or interchangeably for commercial (office, retail, warehouse) and industrial activities. In these industrial subsectors, the energy required for building services'' to provide occupant comfort and necessities (lighting, HVAC, office equipment, computers, etc.) may be at least as important as the more familiar process energy requirements -- especially for electricity and on-peak demand. In this report, published or unpublished information on energy use for building services in the industrial sector have been compiled and analyzed. Seven different sources of information and data relevant to California have been identified. Most of these are studies and/or projects sponsored by the Department of Energy, the California Energy Commission, and local utilities. The objectives of these studies were diverse: most focused on industrial energy use in general, and, in one case, the objective was to analyze energy use in commercial buildings. Only one of these studies focused directly on non-process energy use in industrial buildings. Our analysis of Northern California data for five selected industries shows that the contribution …

Wildlife Protection, Mitigation, and Enhancment Plan: Minidoka Dam: Final Report.
A wildlife protection, mitigation, and enhancement plan has been developed for the US Bureau of Reclamation's Minidoka Dam and Reservoir in south-central Idaho. Specific objectives of this study included the following: Develop protection, mitigation, and enhancement goals and objectives for target wildlife species; identify potential protection, mitigation, and enhancement opportunities to achieve the mitigation objectives; and coordinate project activities with agencies, tribes, and the public. The interagency work group previously assessed the impacts of Minidoka Dam on wildlife. There were estimated losses of 10,503 habitat units (HU's) for some target wildlife species and gains of 5,129 HU's for other target species. The work group agreed that mitigation efforts should be directed toward target species that were negatively impacted by Minidoka Dam. They developed the following prioritized mitigation goals: 1,531 river otter HU's in riparian/river habitat, 1,922 sage grouse HU's in shrub-steppe (sagebrush-grassland) habitat, 1,746 mule deer HU's in shrub-steppe habitat, and 175 yellow warbler HU's in deciduous scrub-shrub wetland habitat. The work group proposed the following preferred mitigation options, in priority order: Provide benefits of 1,706 river otter and yellow warbler HU's by protecting and enhancing riparian/river habitat in south central Idaho; and provide benefits of 3,668 sage grouse and …

Choosing and implementing a computer system for plant lubrication: Nine steps to success
Rapid advances in computer software offer may opportunities for increasing efficiency and productivity; however, choosing the right software package and achieving its full potential can be a challenging task. Lubrication engineers faced with the selection and implementation of a computer system will find that they can increase their chance of success when they follow the nine steps outlined in this paper. These steps provide a solid framework for managing the project through its full life-cycle from initial conception until final retirement of the system. Lubrication Departments that already have computer systems in place can also benefit from these steps by picking up at the corresponding point in the system's life and following the remaining steps.

Novel nanodispersed coal liquefaction catalysts: Molecular design via microemulsion-based synthesis
The objective of this project is to pursue the development of highly dispersed and inexpensive catalysts for improved coal solubilization and upgrading of coal liquids. A novel study of the synthesis of liquefaction catalysts of nanometer size will be carried out. It is based on the molecular design of reverse micelles (microemulsions). These surfactant-stabilized, metal bearing microdrops offer unique opportunities for synthesizing very small particles by providing a cage-like effect that limits particle nucleation, growth and agglomeration. The emphasis will be on iron- and molybdenum-based catalysts, but the techniques to be developed should also be generally applicable. The size of these very small and monodispersed particles will be accurately determined both separately and after in situ and ex situ coal impregnation. The as-prepared nanoparticles as well as the catalyst-impregnated coal or char matrix will be characterized using the following techniques: dynamic light scattering, x-ray diffraction, x-ray photoelectron spectroscopy, scanning and/or transmission electron microscopy, and selective chemisorption.

Comparison of Predicted Optical Performance With Measured Results for Dish Concentrators
Several optical design tools have been developed at the National Renewable Energy Laboratory (NREL) during the past two years. These have been used extensively both in-house and by industry to analyze dish concentrator systems and to optimize performance of such designs. The first program, OPTDSH, models single-element dish concentrators. The second code, ODMF, allows multifacet dish arrays to be modeled. The accuracy of performance simulations by these programs has been established by comparing predicted results with measured on-sun data. ODMF evolved from NREL's High-Flux Solar Furnace (HFSF) design tool, SOLFUR, and in fact is a special case of SOLFUR in which the primary facet array is on sun.'' Consequently, confirmation of the accuracy of SOLFUR would verify the results from ODMF as well. Furthermore, because OPTDSH can be viewed as a single-facet case of ODMF, determination of the precision of SOLFUR/ODMF would also substantiate OPTDSH. Thus, the approach to verifying the correctness of all three codes was to compare flux patterns as predicted by SOLFUR with those actually measured at NREL's HFSF. Measured vs. calculated data have been compared on the basis of flux distribution (in terms of contour plots) and peak flux for both single-facet and multiple-facet cases. Agreement …

Non-stoichiometric defects in YBaCuO thin films
Defects in superconducting YBaCuO thin films deposited by laser ablation are investigated by high resolution transmission electron microscopy. Micrographs reveal numerous defects in the YBaCuO film, falling into four basic classes. One of these is an interesting, non-stoichiometric helical defect structure which possibly corresponds to a growth-related screw dislocation. In general, defects in the YBaCuO film are associated both with growth geometry and with local deviations in stoichiometry. Substrate surface geometry is seen to have a profound effect on the number and type of defects produced. Simulation of annealing transformations using a static lattice, three dimensional, Monte Carlo technique is carried out to gain further insight into specific defect formation mechanisms. The results of these studies suggest preparation conditions that are expected to lead to films with improved critical current densities. 17 refs., 6 figs.

A comparison of radioactive waste from first generation fusion reactors and fast fission reactors with actinide recycling
Limitations of the fission fuel resources will presumably mandate the replacement of thermal fission reactors by fast fission reactors that operate on a self-sufficient closed fuel cycle. This replacement might take place within the next one hundred years, so the direct competitors of fusion reactors will be fission reactors of the latter rather than the former type. Also, fast fission reactors, in contrast to thermal fission reactors, have the potential for transmuting long-lived actinides into short-lived fission products. The associated reduction of the long-term activation of radioactive waste due to actinides makes the comparison of radioactive waste from fast fission reactors to that from fusion reactors more rewarding than the comparison of radioactive waste from thermal fission reactors to that from fusion reactors. Radioactive waste from an experimental and a commercial fast fission reactor and an experimental and a commercial fusion reactor has been characterized. The fast fission reactors chosen for this study were the Experimental Breeder Reactor 2 and the Integral Fast Reactor. The fusion reactors chosen for this study were the International Thermonuclear Experimental Reactor and a Reduced Activation Ferrite Helium Tokamak. The comparison of radioactive waste parameters shows that radioactive waste from the experimental fast fission reactor …

Magnetic field in the SSC arc quad
In part one we report on field calculations along the conductor in the end region of the SSC arc-quad. We have determined that the maximum field in the 2D section is 5.04 tesla located at the pole turn of the inner layer somewhere in the middle of the cable (strand 9)(fields are at 6500 A). At the end'' the maximum field is slightly higher 5.09 tesla located at the overpass (strand 11). The iron contribution was included assuming infinite permeability. In part two we include results of a 3D representation of the magnetic field inside the bore. The complete analysis, for which a brief description has been included here, is described elsewhere. This form for presenting the field is suitable for interfacing with other codes that make use of the 3D field components (particle tracking and stability). 69 figs.

National briefing summaries: Nuclear fuel cycle and waste management
Since 1976, the International Program Support Office (IPSO) at the Pacific Northwest Laboratory (PNL) has collected and compiled publicly available information concerning foreign and international radioactive waste management programs. This National Briefing Summaries is a printout of an electronic database that has been compiled and is maintained by the IPSO staff. The database contains current information concerning the radioactive waste management programs (with supporting information on nuclear power and the nuclear fuel cycle) of most of the nations (except eastern European countries) that now have or are contemplating nuclear power, and of the multinational agencies that are active in radioactive waste management. Information in this document is included for three additional countries (China, Mexico, and USSR) compared to the prior issue. The database and this document were developed in response to needs of the US Department of Energy.

FDA Approved Registration of Erythromycin for Treatment of Bacterial Kidney Disease (BKD) in Juvenile and Adult Chinook Salmon : Annual Report, Reporting Period March 10, 1989 to March 9, 1990.
Erythromycin is a therapeutic substance useful against bacterial kidney disease in salmon. In 1989 we began a multi year project to learn more about erythromycin applied to juvenile and adult salmon, with the goal of achieving registration of erythromycin with the US Food and Drug Administration. To begin the study, we studied the pharmacokinetics of erythromycin administered to both adult and juvenile chinook salmon. We monitored blood plasmas time curves from individual adult fish injected with two forms of injectable erythromycin using one of three routes of administration. In addition, we began experiments to evaluate hatchery applications of erythromycin to individually marked adult salmon, and we recovered blood tissues from these fish at the time of spawning. To determine how to use erythromycin in juvenile salmon, we evaluated the adsorption and elimination of erythromycin applied arterially and orally to individual juvenile fish. In feeding trials we determined the palatability to juvenile chinook salmon of feed made with one of two different carriers for erythromycin thiocyanate. 35 refs., 4 figs. , 3 tabs.

Renewable energy and utility regulation
This report summarizes the results of a joint project on renewable energy of the National Association of Regulatory Utility Commissioners (NARUC) and the US DOE. NARUC'S Task Force on Renewable Energy conducted a review of the current state of renewable energy technologies to evaluate their potential and extract key policy lessons from experience already gained in deployment of these technologies in numerous states. The main focus of this effort has been to clarify how utility regulators affect the development of renewable energy resources. The goal of the project was twofold: (1) identify the factors that have led to success or failure or renewable energy technologies in various energy markets, and (2) to develop an agenda on renewable energy and utility regulation for NARUC and the DOE. This report consists of three sections: renewable energy contributions, costs and potential; factors affecting development of renewable energy resources; and a renewable energy agenda for NARUC.

Application Experience and Field Performance of Silvered Polymer Reflectors
The solar-weighted hemispheric reflectance of unweathered silvered acrylic mirrors exceeds 92%, and specular reflectance into a 4- milliradian, full-cone acceptance angle is greater than 90%. Comparison of outdoor and accelerated tests suggests that the protected silver can resist corrosion for the five-year life that is the current goal. An installation of parabolic troughs has been cleaned monthly for two years, and reflectance is regularly returned to within a few percent of the initial reflectance values. In the presence of moisture, the silver/acrylic bond can delaminate to form a maze of tunnels and destroy specular reflectance. Proper edge preparation and protection delay the initiation of tunnels. 6 refs.

Environmentally sound irrigated agriculture in the arid west: New challenges for water resources planners and environmental scientists
This is an exciting time for water resources planners and environmental scientists in the State and Federal Agencies in California. The growing environmental awareness of the public has raised their interest in the manner by which water is managed and allocated. Current and future impending water shortages are challenging engineers and planners to make sound policy and system operations decisions to maximize the utility of scarce water resources while ensuring that the environment within which we live is adequately protected to the satisfaction of an informed public. New and innovative decision support systems are needed to meet these challenges that are flexible, comprehensible and accurate and which allow the public a more visible role in the planning process. These changes may help to bring the agricultural and environmental communities closer together in finding solutions to water resources problems and wrest policy making for water resources management out of the hands of lawyers and the courts and restore it to those whose livelihoods are affected by the intentions of these policies. 4 refs.

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts
The primary concern of the study during this period has been to examine the origin and basis of the several nonconforming NMR lines reported in our earlier study. Previous studies by earlier investigators indicate that (a) the product distribution in the conversion of synthesis gas to liquid fuels is dependant on the copper/cobalt ratio and (b) that the catalytic results reported by different groups of investigators using the IFP prescription (4) are widely divergent. These observations prompted us to make a critical examination of the effect of metal ratio and the method of preparation on the magnetic character of catalysts.
