Local Invariants and Normal Formsese conditions during environmental testing in space chambers requires that the amount of radiation incident upon the vehicle because of the presence of the chamber walls be minimized. Normally the chamber walls are cooled to about liquid-nitrogen temperature, hence, the amount of radiation emitted

These experiments should, most desirably, be made under conditions which duplicate outer space; otherwise, errors may be introduced which cannot be estimated a

Preliminary experiments indicated additional adsorption was possible if the molybdenum was evaporated onto a liquid-nitrogen-cooled surface[.]. The objectives of the present experiments were: (1) to ascertain the magnitude of the pressure reduction due to adsorption in a baked va

Introduction: Proprietary Developments,ssure of solid hydrogen is about 10. mm Hg. These data were used to construct a temperature-entropy diagram, having lines of constant enthalpy ., constant pressure ., constant volume ., and constant quality . This diagram is shown in Fig. 1.* Such a chart should prove useful in the engineering analy

Published experimental data were used to compute the vapor pressure and heats of vaporization and sublimation at 2° intervals over the temperature range 20° to 100°K, and enthalpy and entropy for the saturated condensed phase, the two-phase region, and the superheated region at 2° In

3D Modeling of Cancellous Bone,d by Burnett in 1936[.]. Since it was conceived, the Burnett method has been applied above the ice point by many investigators[.] and in some instances at low temperatures[.]. Prior to the present investigation, the method had not been verified at cryogenic temperatures by direct comparison with the
