This report outlines a concept and proposal for the space shuttle, a reusable space transportation system, and how it would affect future space missions.

A presentation of the proceedings at the "Conference on Education" held in WOAI-TV studios on November 5, 1971, in San Antonio, Texas, discussing problems, solutions, and additions to the current education system.

This report details a mathematical model addressing the financial structure of the Edgewood Independent School District and the impact of multiple-unit housing construction in the surrounding area, allowing public administrators to calculate the economic impact of alternative programs and polices over a ten year period.

Modification of the combined FI/EI ion source to permit operation in the FD mode is underway. Oxidation-reduction and activation cells were fabricated and assembly of the vacuum system for the activation cell is in progress. High- and low-voltage power supplies needed for emitter preparation were constructed. The sensitivity for field ionization of decane relative to that for ethylbenzene was measured as a function of binary mixture composition, ion-source temperature, and field strength. A gallium frit is being added to the all-glass inlet system. The purity of 25 saturates and naphthenes and 10 single-ring aromatics substituted with alkyl groups was checked using FID/GC.

The objective of the research program is to develop and analyze new concepts for absorption cycles to improve the performance or reduce the cost (or both) of a 3-ton absorption chiller that can be used with solar-collected heat. New refrigerant-absorbent pairs, additives to currently used refrigerant-absorbent pairs, and modifications to the cycle are being investigated. For the initial analyses the use of a fluid at 160 to 230/sup 0/F from a solar collector as a heating source is assumed. In the initial analyses the chiller is to provide chilled water at 45/sup 0/F at full load; alternatively, if a new refrigerant-absorbent pair appears to be amenable for direct cooling of the occupied space, the temperature of the evaporator is to be 45/sup 0/F. Both water cooling and air cooling of the absorber and the condenser are being studied. The use of ambient air at 95/sup 0/F dry bulb and 75/sup 0/F wet bulb temperatures is assumed. With the water-cooled cycles, the initial and operating costs of a properly sized cooling tower will be included. The research consists of five principal tasks: (a) acquisition of information for analysis, (b) definition of criteria for selection of promising refrigerant-absorbent pairs, additives for currently …
