Performance summary of IMP-1 - instrumentation power supply, telemetry, and thermal systems
Photoelectron energy distributions from indium in far ultraviolet
Radiative heat transfer for nongray nondiffuse surfaces in space environment
Contact area between two wavy rough surfaces and experimental determination of contact conductance
Effects of surface states and grain boundaries on free carrier concentration, mobility, and free path of charge carriers in thin films - Design and fabrication of thin film electronic devices
Protective coatings effect on stress corrosion properties of supersonic transport skin materials
Structural failure criteria for viscoelastic materials
Space radiation effects on Apollo mission - dose limits for crew protection
Space radiation effects on Apollo mission - shielding analysis
The analysis of the Apollo radiation environment concentrates on solar flare particle events. These particles are the major radiation hazard to Apollo. The flux of cosmic rays is too low to be significant, and the passage of the space- craft through the Van Allen belts is fast enough to keep the dose to a low level.
