ASHRAE Standard 62-1989 (Standard 62-89) Ventilation for Acceptable Indoor Air Quality'' is the new heating, ventilating, and air-conditioning (HVAC) industry consensus for ventilation air in commercial buildings. Bonneville Power Administration (Bonneville) references ASHRAE Standard 62-81 (the predecessor to Standard 62-89) in their current environmental documents for required ventilation rates. Through its use, it had become evident to Bonneville that Standard 62-81 needed interpretation. Now that the revised Standard (Standard 62-89) is available, its usefulness needs to be evaluated. Based on current information and public comment, the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) revised Standard 62-1981 to Standard 62-89. Bonneville's study estimated the energy and cost implications of ASHRAE Standard 62-89 using simulations based on DOE-2.1D, a computer simulation program which estimates building use hourly as a function of building characteristics and climatic location. Ten types of prototypical commercial buildings used by Bonneville for load forecasting purposes were examined: Large and Small Office, Large and Small Retail, Restaurant, Warehouse, Hospital, Hotel, School, and Grocery. These building characterizations are based on survey and energy metering data and represent average or typical construction and operation practices and mechanical system types. Prototypical building ventilation rates were varied in five steps to …

Following a brief introduction to Fermilab facilities and a review of the accelerator status and plans, the physics potential for the Fermilab III upgrade program is discussed for both the fixed target and collider modes.

Disruptions are observed in the Microwave Tokamak Experiment, MTX (nee Alcator C), over a wide range of plasma parameters. Indeed, disruptions often occur far from the boundaries of the operating space as defined by Hugill and l{sub i}-q plots. Despite this, the general behavior during the disruptive process is generally similar whatever the operating parameters. This report will describe one disruption in detail in order to provide a detailed anatomy of the event.

The purpose of the trip was to conduct a preliminary evaluation of biomass energy development in Yunnan Province, China. The evaluation included an assessment of the potential to grow and convert biomass to electricity, and an evaluation of the institutional relationships, which would be critical to the establishment of a collaborative biomass energy development project. This site visit was undertaken to evaluate the potential of an integrated biomass energy project, including the growing and handling of biomass feedstocks and its conversion to electricity. Based on this site visit, it was concluded that biomass production risks are real and further research on species screening and experiments is necessary before proceeding to the conversion phase of this project. The location of potential sites inspected and the logistics required for handling and transporting biomass may also be a concern. The commitment of support (labor and land) and leadership to this project by the Chinese is overwhelming exceeding all pre-site visit expectations. In sum, there is a definite opportunity in Yunnan for an integrated biomass energy project and a potential market for US technology.

This report summarizes the activities under LLNL Purchase Order B089367, the purpose of which is to support the University/Lawrence Livermore National Laboratory Magnetic Fusion Program by evaluating the status of research relative to other national and international programs and assist in long-range plans and development strategies for magnetic fusion in general and for ITER in particular.'' Two specific subtasks are included: to review the LLNL Magnet Technology Development Program in the context of the International Thermonuclear Experimental Reactor Design Study'' and to assist LLNL to organize and prepare materials for an International Thermonuclear Experimental Reactor Design Study information meeting.''

As Annex 20 enters the final year, deliverables in the form of reports, guidelines, and data formats are nearing completion. The Reporting Guidelines for the Measurement of Air Flows and Related Factors in Buildings will be published by the AIVC next month and was presented to the research community at the 11th AIVC Conference. Measurement guidelines and state-of-the-art equipment descriptions are part of a comprehensive manual, Measurement Techniques Related to Air Flow Patterns Within Buildings -- An Application Guide, in the final stages of preparation in Part 2 of Annex 20, together with reports on how to estimate the effects of flow through large openings, as well as contaminant movements in buildings. The Measurement Manual will include the latest information from the AIVC. The next AIVC Conference, in Ottawa, September 1991, will feature more than 12 presentations of Annex 20 results, including the information from Part 1 which has focused on the detailed air flow patterns in a variety of single-room configurations. Both complex modelling (including CFD) and detailed measurements have been completed, and it is now desirable that added tests be made in the next months by the University of Illinois, BERL, representing the US in Part 1 for …

In this note the number of Cerenkov photons generated per unit time by synchrotron radiation characterized by its characteristic energy {var epsilon}{sub c} is calculated as a function of the ratio of {var epsilon}{sub c} to the cutoff energy of the Cerenkov monitor. These results are used to determine approximate scaling relations for the beamstrahlung flux. 6 refs., 3 figs.

The traveler collaborated with M.J.M. Leask, J.M. Baker, B. Bleaney, and others at the Clarendon Laboratory, Oxford University, Oxford, UK, to Study Tetragonal rare-earth phosphates and vanadates by optical and magnetic spectroscopy. This work is related to similar studies that have been performed at ORNL by the Synthesis and Properties of Novel Materials Group in the Solid State Division.

Narrow correlated positron-electron peaks discovered in superheavy nuclear collisions may be signatures for previously undetected neutral particle-like objects having masses of 1--2 MeV/c{sup 2}. We have designed an experiment to definitively test this hypothesis by searching for resonant states formed directly in the scattering of monoenergetic electrons incident on a gas of cold positrons confined magnetically in a Malmberg trap. This technique will provide a hundred-fold improvement in sensitivity to e{sup +}e{sup {minus}} resonances compared to previous positron-beam, thin-foil scattering experiments. Together with a recoil-shadow technique, this experiment will explore a five decade range in neutral-particle lifetimes (10{sup {minus}13}s to 10{sup {minus}8}s) which cannot be probed directly to other methods. 14 refs., 2 figs., 1 tab.

The overall objective of this work was to promote nuclear medicine applications in oncology. This is being done by improving the scientific basis of diagnosis, treatment and treatment follow-up with cyclotron-produced tracers. For diagnostic use, positron-emitting isotopes such as Ga-66 and I-124 are being used. Initial studies on the characterization of He-4 particle energies required for Ga-66 production have been completed. Parameters for I-124 radiolabelling of monoclonal antibodies have been determined; the labelled antibodies have been used in animal studies using positron emission tomography (PET) to quantify antibody concentration within tumors in vivo. Imaging physics studies have demonstrated that I-124 can be quantitatively imaged by PET, even in the presence of 100-told greater concentrations of I-131. Measurement of concentrations of label in vivo has been accomplished in nuclei mice bearing neuroblastoma tumors and nude rats bearing human ovarian cancer cells. These studies have major implications for both the quantification of dosimetry and quantification kinetic assessment of anti-tumor antibody localization in vivo. For treatment of tumors, F-18 has been incorporated in 2-fluoro-2-deoxy glucose and 5-fluoro uridine, and O-15 labelled water has been produced. Reagents incorporating C-11 and N-13 are under development. In a related area, C-14 labelled colchicine is being studied …
