The giant dipole (GD) parameters of peak energy, width, and cross section were satisfactorily correlated for elements from V to Bi, assuming two overlapping peaks with a separation dependent on deformation. The energy dependence of the GD resonance is assumed to have a Breit-Wigner form, but with an energy-dependent width. The resulting gamma-ray strength function model is used to predict neutron capture cross sections and gamma-ray spectra for isotopes of Ta, Os, and Au. 23 references.

Production processes for low-cost organic antireflection (AR) coating and etched AR coating on glass are being developed and improved. The etched AR coating process has been scaled-up to etch full-size glass panes but the chemical control of the etching solution remains a problem. Analytical methods including high pressure liquid chromatography (HPLC), flame excited atomic absorption, infrared spectroscopy, Coulter counter techniques, and liquid index of refraction measurements were examined for application to this process monitor and control problem. A phenomenological model for the key reaction species in the etching process is presented along with a monitor control scheme using refractive index measurements to set the initial reactant concentrations and HPLC to track in-process concentrations. The environmental durability of the organic AR coating of fused FEP-120 Teflon dispersion has been improved by the use of a hydrofluoric acid etch/silane coupling agent pretreatment. Improved coating processing techniques were developed culminating in the demonstration of scale-up feasibility for this process for glass panels up to 1 ft x 1 ft with good batch sample to sample repeatability.

This report provides a regional synthesis of geology, geochemistry, hydrology and geophysical data for the Socorro, New Mexico, area. It is based principally on extensive drill-hole data supplied by, and proprietary to, Gulf Mineral Resources Company and Sunoco Energy Development Co. These temperature-gradient and heat-flow data are integrated with older gradient and heat-flow data, groundwater chemistry, studies of local seismicity, regional and local geologic mapping, and other data. This synthesis yields a revised estimate of the geothermal energy potential for the Socorro area. it should be recalled that attention has been focused on Socorro and vicinity because of reported high heat flow and probable magmatic bodies within the shallow crust. Some 20 man-days of effort have gone into this study, exclusive of time spent earlier in logging temperature gradients and studying drill-hole cuttings.

An approach to low-cost instrumentation and performance evaluation of passive solar heated buildings is presented. Beginning with a statement of the need for a low-cost approach, a minimum list of measured quantities necessary to compute a set of recommended performance factors is developed. Conflicts and confusion surrounding the definition of various performance factors are discussed and suggestions are made for dealing with this situation. Available instrumentation and data processing equipment is presented. The recommended system would monitor approximately ten variables and compute numerous performance factors on site at a projected system cost of less than $3,000 per installation.

The solar reflectance, transmittance, and absorptance of common materials used for solar collector fabrication have been compiled for easy reference. The data are derived from solar weighted averaging techniques and can be used for initial calculations of collector performance.

A review of existing models identified several effects that may need consideration in further model development. Most of these effects involved coupling equations through variable property values rather than through omission of any significant mechanism. However, it was also shown that more than one mechanism may adequately simulate a given set of experimental data and additional experimental data are needed to establish which (if any) of the possible mechanisms would actually control conditions in a nuclear waste repository. In particular, it is believed that mathematical modeling of major thermomechanical effects can be accomplished with finite element analysis computer programs, provided that adequate thermomechanical property data of salt and overburden are attained. An attempt was made to develop a general set of differential equations for simulating momentum, mass, and energy flows in geologic formations in order to illustrate the possible mechanisms and point out those included and not included in existing models. Most of the mechanisms are included in some manner in existing models although some approximations may not be adequate. More experimental data are required to assess the importance of most omitted mechanisms. Analysis of some data on brine migration in salt indicated that two mechanisms, acting simultaneously, could adequately …

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

The main objectives of the 3rd Annual Biomass Energy Systems Conference were (1) to review the latest research findings in the clean fuels from biomass field, (2) to summarize the present engineering and economic status of Biomass Energy Systems, (3) to encourage interaction and information exchange among people working or interested in the field, and (4) to identify and discuss existing problems relating to ongoing research and explore opportunities for future research. Abstracts for each paper presented were edited separately. (DC)
