[Letter from Bill McCarter and Nancy Cason to Janice Wiggins, May 10, 1991]
Photocopy of a letter from Bill McCarter and Nancy Cason, North Texas Institute for Educators on the Visual Arts, to Janice Wiggins, Art Supervisor of Dallas ISD. Thanking Wiggins for her time working with NTIEVA, and meeting with Dr. Brooks-Ray and Howard Dunn to discuss interest in the program for staff development. The Institute and the district face uncertain economic conditions but McCarter and Cason believe if they could stretch their first year budget they could pay a team member (kindergarten and first grade teacher, art specialist and principal) a stipend of $50 a day to attend the three-week institute during the summer. However, since Dallas was not written into the original implementation grant they will have to review it with the Getty Center and cannot promise continued support past the year.

Benchmark field study of deep neutron penetration
A unique benchmark neutron field has been established at the Lawrence Livermore National Laboratory (LLNL) to study deep penetration neutron transport. At LLNL, a tandem accelerator is used to generate a monoenergetic neutron source that permits investigation of deep neutron penetration under conditions that are virtually ideal to model, namely the transport of mono-energetic neutrons through a single material in a simple geometry. General features of the Lawrence Tandem (LATAN) benchmark field are described with emphasis on neutron source characteristics and room return background. The single material chosen for the first benchmark, LATAN-1, is a steel representative of Light Water Reactor (LWR) Pressure Vessels (PV). Also included is a brief description of the Little Boy replica, a critical reactor assembly designed to mimic the radiation doses from the atomic bomb dropped on Hiroshima, and its us in neutron spectrometry. 18 refs.

World nuclear fuel cycle requirements 1991
The nuclear fuel cycle consists of mining and milling uranium ore, processing the uranium into a form suitable for generating electricity, burning'' the fuel in nuclear reactors, and managing the resulting spent nuclear fuel. This report presents projections of domestic and foreign requirements for natural uranium and enrichment services as well as projections of discharges of spent nuclear fuel. These fuel cycle requirements are based on the forecasts of future commercial nuclear power capacity and generation published in a recent Energy Information Administration (EIA) report. Also included in this report are projections of the amount of spent fuel discharged at the end of each fuel cycle for each nuclear generating unit in the United States. The International Nuclear Model is used for calculating the projected nuclear fuel cycle requirements. 14 figs., 38 tabs.

Electron energies in metals
The modern era of electron-electron interactions began a decade ago. Plummer's group initiated a program of using angular resolved photoemission to examine the band structure of the simple metals. Beginning with aluminum, and carrying on to sodium and potassium, they always found that the occupied energy bands were much narrower than expected. For example, the compressed energy bands for metallic potassium suggest a band effective mass of m* = 1.33m{sub e}. This should be compared to the band mass found from optical conductivity m*/m{sub e} = 1.01 {plus minus} 0.01. The discrepancy between these results is startling. It was this great difference which started my group doing calculations. Our program was two-fold. On one hand, we reanalyzed the experimental data, in order to see if Plummer's result was an experimental artifact. On the other hand, we completely redid the electron-electron self-energy calculations for simple metals, using the most modern choices of local-field corrections and vertex corrections. Our results will be reported in these lectures. They can be summarized as following: Our calculations give the same effective masses as the older calculations, so the theory is relatively unchanged; Our analysis of the experiments suggests that the recent measurements of band narrowing …

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.

Integrated dry NO sub x /SO sub 2 emissions control system
This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with convention ash removal equipment. These processes include low-NO{sub x} burners and urea injection for NO{sub x} control, sodium- or calcium-based sorbent injection for SO{sub 2} control, and flue gas humidification to enhance the reactivity of the SO{sub 2} control compound.

Chasing the x sub f dependence of J/. Psi. production
We discuss the combined effects of hard scattering processes and intrinsic heavy-quark components in the hadron wavefunction on the x{sub f} dependence of J/{psi} production. The A dependence arises from nuclear absorption, comover interactions, shadowing of parton distributions, and intrinsic heavy quarks. 9 refs., 1 fig.

Novel macrocyclic carriers for proton-coupled liquid membrane transport
The objective of our research program is to elucidate the chemical principles which are responsible for the cation selectivity and permeability of liquid membranes containing macrocyclic carriers. Several new macrocyclic carriers were synthesized during the last three year period, including selenium-containing macrocycles, new crown-4 structures, and several new crown structures containing nitrogen based heterocycles as substituents in the principal macrocyclic ring. The cation binding properties of these macrocycles were investigated by potentiometric titration, calorimetric titration, solvent extraction, and NMR techniques. In addition, hydrophobic macrocycles were incorporated into dual hollow fiber membrane systems to investigate their membrane performance, especially in the proton-coupled transport mode. It was found that the dual hollow fiber system maintains the cation selectivity and permeability of supported liquid membranes, while enhancing membrane stability. The diffusion limited transport model was expanded to account for membrane solvent effects. Furthermore, Eu{sup 2+} transport was found to be similar to that of strontium and much higher than that of the lanthanides, in supported liquid membrane systems.
