Development and testing of heat transport fluids for use in active solar heating and cooling systems
Work on heat transport fluids for use with active solar heating and cooling systems is described. Program objectives and how they were accomplished including problems encountered during testing are discussed
Study of the murine viruses present in 'germfree' mice Final report, 1 Sep. 1968 - 30 Jun. 1970
Murine viruses in germfree mice selected for extraterrestrial life testing of Apollo lunar sample
Development, testing, and certification of Owens-Illinois model SEC-601 solar energy collector system
The final results are presented of the additional development work on the existing air-cooled solar energy collector subsystem for use with solar heating and cooling systems. The report discusses the intended use of the final report, describes the deliverable end items, lists program objectives, relates how they were accomplished, deals with problems encountered during fabrication and testing, and includes a certification statement of performance. The report shows that the products developed are marketable and suitable for public use
Advanced flight design systems subsystem performance models. User guide: Environmental analysis routine library
A user guide for a library of interactive computer routines used to develop performance analysis models of specific environmental control and life support subsystems is presented
Advanced flight design systems subsystem performance models. Sample model: Environmental analysis routine library
A sample environmental control and life support model performance analysis using the environmental analysis routines library is presented. An example of a complete model set up and execution is provided. The particular model was synthesized to utilize all of the component performance routines and most of the program options

Fluid transients in closed conduit
GEOS satellite tracking corrections for refraction in the troposphere
Comparison of magnitude at different elevation angles of tropospheric refraction formulation
Preliminary design study of a regenerative life support system information management and display system
The instrumentation requirements for a regenerative life support systems were studied to provide the earliest possible indication of a malfunction that will permit degradation of the environment. Four categories of parameters were investigated: environmental parameters that directly and immediately influence the health and safety of the cabin crew; subsystems' inputs to the cabin that directly maintain the cabin environmental parameters; indications for maintenance or repair; and parameters useful as diagnostic indicators. A data averager concept is introduced which provides a moving average of parameter values that is not influenced by spurious changes, and is convenient for detecting parameter rates of change. A system is included to provide alarms at preselected parameter levels
Toxicity of materials in fire situations: Laboratory data obtained at the University of San Francisco
Approximately 300 materials were evaluated using a specific set of test conditions. Materials tested included wood, fibers, fabrics and synthetic polymers. Data obtained using 10 different sets of test conditions are presented
