[Letter from Cassandra Broadus to Melanie Wright, March 6, 1991]

Description: Photocopy of a letter from Cassandra Broadus, North Texas Institute for Educators on the Visual Arts, to Melanie Wright, Dallas Museum of Art. Broadus requests the use of two or three permanent pieces from the DMA to use in "Art-O-Gram" and "Class Acts" an art education newspaper series in the Fort Worth Star Telegram. The articles are designed for children to give them something more than just an art project but to talk about and view work critically and develop better communication skills.

A survey of air flow models for multizone structures

Description: Air flow models are used to simulate the rates of incoming and outgoing air flows for a building with known leakage under given weather and shielding conditions. Additional information about the flow paths and air-mass flows inside the building can only by using multizone air flow models. In order to obtain more information on multizone air flow models, a literature review was performed in 1984. A second literature review and a questionnaire survey performed in 1989, revealed the existence of 5… more

Optimizing procedures for a human genome repository

Description: Large numbers of clones will be generated during the Human Genome Project. As each is characterized, subsets will be identified which are useful to the scientific community at large. These subsets are most readily distributed through public repositories. The American Type Culture Collection (ATCC) is experienced in repository operation, but before this project had no history in managing clones and associated information in large batches instead of individually. This project permitted the ATCC t… more

A method to estimate the concentration of elements in smoke from burning vegetation growing in contaminated soil

Description: The Savannah River Site has areas where soil is contaminated with metals and/or radionuclides. Many of these areas are surrounded by native vegetation which is growing adjacent to the area and where the roots have penetrated into the contaminated soil of the area. In some cases vegetation has actually invaded the contaminated area. Even though the volume of contaminated vegetation is small, there are problems associated with its disposal. Vegetation decomposes quickly after burial and the volum… more

Demonstration of rapid and sensitive module leak certification for space station freedom

Description: A leak detection and quantification demonstration using perflurocarbon tracer (PFT) technology was successfully performed at the NASA Marshall Space Flight Center on January 25, 1991. The real-time Dual Trap Analyzer (DTA) at one-half hour after the start of the first run gave an estimated leak rate of 0.7 mL/min. This has since been refined to be 1.15 {plus minus} 0.09 mL/min. The leak rates in the next three runs were determined to be 9.8 {plus minus} 0.7, {minus}0.4 {plus minus} 0.3, and 76 … more

Fundamental studies of catalytic gasification

Description: Studies of the catalytic steam gasification of carbon solids continued. A considerable number of important findings have been made. Recently limited experimentation has been carried out on the production of C{sub 2} hydrocarbons from methane in the presence of Ca/K/Ni oxide catalysts and of oxygen, carbon and water. The main finding thus far has been that C{sub 2} yields of 10--13% can be obtained at about 600{degrees}C or 150{degrees} lower temperature than described in the literature for simi… more

3D field harmonics

Description: We have developed an harmonic representation for the three dimensional field components within the windings of accelerator magnets. The form by which the field is presented is suitable for interfacing with other codes that make use of the 3D field components (particle tracking and stability). The field components can be calculated with high precision and reduced cup time at any location (r,{theta},z) inside the magnet bore. The same conductor geometry which is used to simulate line currents is … more

Cost-Effectiveness of Compact Fluorescent Lighting

Description: Compact fluorescent technologies have been steadily improving. There has been increased interest in utilizing compact fluorescents to provide cost-effective energy savings for electric utilities in the residential sector. Several utilities in the United States have already distributed compact fluorescents to consumers free of charge. This study assesses the cost-effectiveness of compact fluorescents from the perspectives of consumers and utilities in the Pacific Northwest, where electricity rat… more

Ductile-Brittle Transition Temperature testing of tungsten using the three-point bend test

Description: Three-point bend tests were performed to determine the Ductile-Brittle Transition Temperatures (DBTTs) of forged and chemical vapor deposition (CVD) tungsten. Testing was performed under quasi-static conditions at temperatures between 23{degrees}C and 450{degrees}C using a forced-air environmental chamber. Load-displacement data from the three-point bend tests indicated that the constitutive behavior of the materials tested varied considerably. Finite element modeling of the three-point bend te… more

Alternate design concept for the SSC dipole magnet cryogenic support post

Description: New materials and developments in the field of advanced composites have created the opportunity to take a fresh look into the design of the cryogenic supports for SSC collider dipole cryostats. Although the present reentrant post design meets the structural and thermal requirements, its assembly requires precision and proficiency. The objective of the proposed alternate concept is to reduce the overall cost of the support post by means of simplifying and optimizing its component design and asse… more

Meson and baryon correlation studies using the PEP-TPC/2. gamma. Facility

Description: Results on vector meson, and strange and charmed-baryon production are presented for data taken during the period 1982--1986 using the TPC/2{gamma} detector at PEP. Vector mesons ({rho}{sup 0}, K{sup *} and {phi}) with 0, 1 and 2 strange quarks are used to obtain redundant measures of strange-quark suppression and of the vector to pseudoscalar ratio in hadronization. Measurements of the production rates of {Lambda}, {Xi}{sup {minus}}, {Omega} and {Xi}{sup *0} hyperons and for the {Lambda}{sub c… more

Status of 4-cm-aperture, 17-m-long SSC dipole magnet R D program at BNL

Description: Over the last year, several 4-cm-aperture, 17-m-long dipole magnet prototypes were built by Brookhaven National Laboratory (BNL) under contract with the Superconducting Super Collider (SSC) Laboratory. These prototypes are the last phase of a half-decade-long R D program, carried out in collaboration with Fermi National Accelerator Laboratory and Lawrence Berkeley Laboratory, and aimed at demonstrating the feasibility of the SSC main ring magnets. They also lay the ground for the 5-cm aperture … more

Re-powering and site recycling in a competitive environment

Description: Re-powering and site recycling are strategies designed to expand electric generating capacity by using depreciated assets. The resource base for the these strategies is large. By 1995, over 170,000 MW of fossil-fired capacity will be in excess of thirty years old, and approaching the end of its conventional economic lifetime. This paper explores how these assets might be developed using competitive market forces. While some re-powering is being pursued under traditional ratebase regulation, the… more

A progress report on the Berkeley search for distant supernovae to measure. Omega

Description: Over the past two years, in collaboration with the Anglo-Australian Observatory, we have constructed a prototype version of the hardware and software needed to discover distant supernovae for a measurement of {Omega}, the ratio of the average density of the universe to the critical density. To make this measurement, we will use Type Ia supernova, which are now thought to be adequate standard candles for this purpose. 5 refs.
