From international conference on bone mineral measurement; Chicago, Illinois, USA (12 Oct 1973). Abstracts of papers presented at the international conference on bone mineral measurement are presented. The papers were grouped into two sessions: a physical session including papers on measuring techniques, errors, interpretation and correlations, dual photon techniques, and data handling and exchange; a biomedical session including papers on bone disease, osteoporosis, normative data, non-disease influences, renal, and activity and inactivity.

This second of the four volumes of the Geothermal Leasing Program final impact statement contains the individual environmental statements for the leasing of federally owned geothermal resources for development in three specific areas: Clear Lake-Geysers; Mono Lake-Long Valley; and Imperial Valley, all in California. It also includes a summary of the written comments received and departmental responses relative to the Draft Environmental Impact Statement issued in 1971; comments and responses on the Draft Environmental Impact Statement; consultation and coordination in the development of the proposal and in the preparation of the Draft Environmental Statement; and coordination in the review of the Draft Environmental Statement.

A review of selected portions of the ARHCO waste tank farm monitoring methods and systems was made. Only preliminary evaluations were made as the study was carried out over a period of only ten days. The study was requested by the Operation Support Engineering Department of ARHCO and the objectives as developed were divided into four tasks. Briefly, these were: evaluation of the waste tank dry well monitoring and data processing systems; evaluation of the accuracy (and precision) of material balance calculations for transfers from one tank to another tank; evaluation of the capabilities of material balance techniques for the detection of leaks in evaporator bottoms loop systems; and evaluation of the general operability of liquid level instrument systems currently in use and alternatives to these systems. The objectives of these tasks are restated in more detail in each of the sections below. An overview of the entire Hanford radioactive waste program including a limited description of the physical equipment involved can be found in PWM-530, Hanford Radioactive Waste Management Plans. Additional efforts have been initiated to establish an overall R and D program to more fully evaluate these systems and other factors relative to the successful operation of the …

Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Reasonably firm delivery schedules were arranged for all of the critical Task 1 engine parts. However, the program will likely have to continue to function with loaner turbine wheels for the next few months. Vehicle A was built and utilized for running demonstrations at both EPA and NASA. Engine 5 (Vehicle B) was built and is being checked out. Upgraded Engine design guidelines were jointly worked out and agreed to with EPA and NASA. Life testing on the loaner endurance engine was extended beyond the 3500-hour milestone. Improvements are being made to extend low emissions Baseline burner life, currently under 300 hours. State-of-the-art ceramic regenerator cores were received from two sources and are being bench checked. Drive and seal system procurement is delaying hot rig testing. Analytical studies were made to determine suitability for the upgraded engine. AiResearch was awarded the integrated control system subcontract. They have initiated work on a simulation …

Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emission Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard-size American automobile. Procurement delays have caused an additional one-month slippage in engine deliveries. All test cell conversion and preparation tasks are complete. Assembly, qualification, and delivery to NASA of Engine 3 were accomplished. Vehicle installation design tasks were completed. Vehicle structural modifications were completed. Initial operation of the first vehicle has slipped two weeks due to engine delivery schedule changes. The planned training activity for the NASA technician took place. Endurance activity has included continued testing of molded insulation and the start of testing of new coarse pitch regenerator drive gears. Testing of a variable geometry combustor for control schedule optimization started. The all-ceramic regenerator core program was formulated, and work started on design and fabrication or procurement of core, drive, and seal hardware required specifically for these cores. The integrated control system sub-contract is delayed pending resolution of the adjustments to the scope of work. An elasto-plastic stress analysis program is being written in …

The United Aircraft Research Laboratories are engaged in a program to investigate the use of a dense, mirror-confined, laser-produced plasma as the target for a neutral-injection beam and to examine this technique for establishing and maintaining a high-temperature, high-density, steady-state, mirrorconfined fusion plasma. The program is a direct extension of the current UARL investigations of the capture and confinement of laser-produced plasmas in a minimum-B mirror field. The overall program plan of the UARL Laser-Initiated Target Experiment involves four parts. The first of these is the laser heating of a solid particle positioned within the experiment chamber by an ultrahigh- vacuum suspension system to create a filly ionized plasma of ~10/sup 16/ to 10/ sup 17/ ions and electrons at a temperature of 0.5 to 1 keV. The second part of the program is the capture and confinement of the high-temperature laser-produced plasma to form a stable, high-density (>10/sup13/ cm/sup -3/), mirror-confined target plasma which fills an appreciable fraction of the mirror field volume. Heating of the confined-target plasma to ~10 keV by charge-exchange interaction with an injected energetic neutral beam comprises the third part of the program, and the fourth is the creation of a collisional, steady-state, mirror-confined plasma …
