Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82/sup 0/F desired for these prawns, a geothermal resource having a 150/sup 0/F temperature or higher, is needed. The best estimate is that 150/sup 0/F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150/sup 0/F geothermal water.

A multicompartment photoelectrodialytic demineralization cell is provided with a buffer compartment interposed between the product compartment and a compartment containing an electrolyte solution. Semipermeable membranes separate the buffer compartment from the product and electrolyte compartments. The buffer compartment is flushed to prevent leakage of the electrolyte compartment from entering the product compartment.

The disclosure is directed to an acoustical heat pumping engine without moving seals. A tubular housing holds a compressible fluid capable of supporting an acoustical standing wave. An acoustical driver is disposed at one end of the housing and the other end is capped. A second thermodynamic medium is disposed in the housing near to but spaced from the capped end. Heat is pumped along the second thermodynamic medium toward the capped end as a consequence both of the pressure oscillation due to the driver and imperfect thermal contact between the fluid and the second thermodynamic medium.

The permitting process is reviewed. The environmental data requirements are presented for: air resources; vegetation and wildlife; geotechnical environment; surface waters; cultural resources; public health, industrial hygiene, and noise; land use and socio-economic factors; and scheduling and budgets. (MHR)

The following disciplines are covered: air resources; land use, vegetation, and wildlife, geotechnical environment; surface water, ground water, and waste disposal; cultural resources; health, industrial hygiene and noise; and socio-economics. The following are presented for each discipline: general comments; regulations, ordinances, statutes, and guidelines; bibliography with abstracts; and sensitive environmental issues. (MHR)

The magnet power supply for the Tandem Mirror Experiment Upgrade (TMX Upgrade) contains 24 groups of dc rectifiers that feed the water-cooled magnets. Each group consists of five or less rectifiers, connected in series. All 24 are current-regulating, using phase-controlled bilateral thyristors in the rectifier transformer primaries. The electric utility system must furnish reactive power to these phase-controlled thyristors as well as to the cmmutating diodes in the rectifier bridges.

GeoProducts Corporation and the California Department of Water Resources have jointly proposed to develop a 55 MWe power plant in Lassen County, California. The proposed power plant is unique in that it will utilize geothermal heat and wood fuel to generate electrical power, the first attempt to utilize these resources together on a commercial scale. This report identifies requirements for new environmental information that must be generated for permit applications and for preparation of environmental documents required by CEOA and NEPA; presents a schedule for generating new environmental data, for preparing and submitting permit applications, and for obtaining permits; presents a budget for permitting, licensing and environmental assessments as required by applicable laws, regulations and procedures; and investigates the step needed to qualify for a Small Power Plant Exemption by the State Energy Commission.

We have studied Bacillus subtilis, Bacillus pumilus and Bacillus caldolyticus to ascertain the molecular mechanism of the ability to growth at high temperatures. B. subtilus wild type strains grow in minimal salts medium at a mesophilic temperature (37/sup 0/C) but not at a thermophilic temperature (56/sup 0/C). However, they do grow at 56/sup 0/C in complex rich media. Analysis of their nutritional requirements revealed that these bacteria require pyridoxine or aspartic acid and threonine to grow at 56/sup 0/C indicating that they are temperature sensitive mutants. Furthermore, mutants of B. subtilis which are able to grow on minimal salts media at 56/sup 0/C can be readily isolated. Therefore, it appears that the lack of growth of the wild type strain in minimal salts media at 56/sup 0/C is due to the instability of an anabolic enzyme. In contrast to B. subtilis, B. pumilus has never been observed to growth above 50/sup 0/C. However, our studies show that mutants of B. pumilus and B. subtilis which grow at 68/sup 0/C can be easily isolated. The isolation of such mutants strongly supports the idea that one gene can determine the ability to grow at extreme temperatures.

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.
