Multiple phonon ultrasonic paramagnetic resonance generation and absorption for studying spin-lattice interactions between U ions and calcium fluoride
Japan-U.S. meteorological rocket project, discussing launchings of MT-135 and Arcas rockets from NASA Wallops Island facility
Venus cloud layer models compared with observations in U, B and V spectral regions
Ionized H-u mixtures high temperature viscosity and diffusivity calculation method
U-tube containing liquid indicates pressure differences in a leakage tester. This tube, connecting two containers, indicates that the amount of leakage over a set period of time is calculated from the pressure and gas volume.
Multigroup calculations of resonance neutron capture in thick slab of depleted U-238
Lead isotope composition and concentrations of U, Th, Ra, total Pb and Pb 210 in recent volcanic rocks, noting disequilibrium due to chemical fractionations
Group cross section generating techniques to calculate neutron capture rates and spatial capture distribution in depleted thick U slab, using GAROL program
Modified model for vibration-dissociation relaxation coupling phenomena in nonequilibrium high temperature gas flow, discussing parameter U variation with kinetic temperature
Least squares analyses of experimental differential cross-section data for the U-235 nucleus have yielded single level Breit-Wigner resonance parameters that fit, simultaneously, three nuclear cross sections of capture, fission, and total.
Alpha particle emissivity measurement of moon by Explorer 35 spacecraft for U 238 abundance in outer crust
Spatial resonance capture rates for U-238 thick slabs to correct gamma ray attenuation errors in broad group shielding calculations
Iron troilite meteorites lead isotopic, Pb and U concentrations, considering fractionation and terrestrial contamination effects
U and Th abundances correlation in tektites and achondrites based on oxygen isotopic composition of lunar rock specimens
Open cycle gas core nuclear rocket reactor, evaluating critical mass for U isotopes
Apollo 11 lunar material actinide element abundance and isotopic composition, examining Th, U and transuranium elements by mass spectrometric and radiometric techniques
Apollo 11 lunar rocks, breccia and fines U, Th and Pb isotopes systematics, considering implications for lunar history
This compilation consists of papers presented at the NASA Symposium on Flight Test Results Pertaining to the Space Shuttlecraft, held at the NASA Flight Research Center, Edwards, Calif., on June 30, 1970. The symposium was divided into the following sessions. I. Lifting Body Flight Test Results and II. Additional Space Shuttle Oriented Studies. Papers were presented by representatives from the NASA Flight Research Center and the U. S. Air Force Flight Test Center. A list of attendees is included.
