The objective of this research project is to investigate a geothermal anomaly of high heat flow discovered in 1969 in central Montana, and to determine how this natural resource might be developed as a source of useful energy. Under Phase I, the natural resource will be explored, drilled, and modeled at an estimated cost of $2,588,935 over a 3-year period. Phase II, depending upon the nature of the heat source, will be developing the resource under a cooperative effort of government and private industry. This environmental analysis is intended to cover the drilling and logging operations noted under Phase I, the only work being undertaken at this time. As can be seen from Figure 1, further tests may be run at this site in later phases of the study. But since the nature of these tests are highly dependent on the results of Phase I, it is not considered productive to speculate on their environmental impact. As is show, however, any later experiments would cover a range of underground experiments, some of which consume water and others which would produce water. Before a meaningful analysis of such work can be written, it will be necessary to analyze the results of …

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, John L. Hill, regarding a legal question submitted for clarification: Under present law, can the Grayson County Commissioners Court legally amend the 9173 County Budget and allow a blanket increase in salaries of county employees, effective January 1, 1973.

During the quarter covered (October 15, 1972 to February 15, 1973), additional models of the nuclear engine were implanted in calves to evaluate the chronic effects of weight and size. Further characterization of the bench test heart pump was performed, The effect of pump rate on cardiac output was evaluated. The effect of outflow (anterial) pressure on cardiac output was evaluated. Bjork- Shiley valves with stainless steel disks and pyrolitic carbon disks were tested and the effect of cardiac output evaluated. A design of a quick connect system to enable rapid connection of the atrial cuffs and anterial graphs to the blood pump was undertaken. Molds of the implantable version of the ventricles were completed, and construction techniques and evaluation of the ventricles is now in progress. A protocol for the implantation of the pump mechanism into calves for testing is under consideration. (auth)
