A comparison of the experimental subsonic pressure distributions about several bodies of revolution with pressure distributions computed by means of the linearized theory
"An analysis is made of the effects of compressibility on the pressure coefficients about several bodies of revolution by comparing experimentally determined pressure coefficients with corresponding pressure coefficients calculated by the use of the linearized equations of compressible flow. The results show that the theoretical methods predict the subsonic pressure-coefficient changes over the central part of the body but do not predict the pressure-coefficient changes near the nose. Extrapolation of the linearized subsonic theory into the mixed subsonic-supersonic flow region fails to predict a rearward movement of the negative pressure-coefficient peak which occurs after the critical stream Mach number has been attained" (p. 1125).

Radiometric Reconnaissance Examination in Southeastern Pennsylvania and Western New Jersey
Abstract: In May 1950, 350 miles of road was traversed in the vicinity of a torbernite locality in New Jersey. The radioactivity of the area traversed was two to three times above normal, averaging 0.003 percent equivalent uranium. It is estimated that there is 1,000 tons of rock averaging 0.009 percent uranium at the torbernite locality. The presence of this area of above-normal radioactivity suggests that further study is needed in the Piedmont belt and the flanking sediments, which may contain economic deposits of uranium minerals.

Flight investigation of the effect of control centering springs on the apparent spiral stability of a personal-owner airplane
Report presents the results of a flight investigation conducted on a typical high-wing personal-owner airplane to determine the effect of control centering springs on apparent spiral stability. Apparent spiral stability is the term used to describe the spiraling tendencies of an airplane in uncontrolled flight as affected both by the true spiral stability of the perfectly trimmed airplane and by out-of-trim control settings. Centering springs were used in both the aileron and rudder control systems to provide both a positive centering action and a means of trimming the airplane.

The Fluorapatite System of Equilibria in the Conditions of Formation of Sedimentary Rocks
From translator's abstract: "As part of unified research on the behavior of the fluoride ion in sedimentary rocks, the present study deals with the system CaO-P2O5-HF-H20 at 25 degrees C. under conditions of sea sedimentation. The precipitated phases, their fields of crystallization and stability, the fluorine-phosphorus coefficient, and the isomorphism of fluorhydroxl ions in the apatite lattice are considered and illustrated by orthogonal projections."

Conditions of the Formation of Fluorite in Sedimentary Rocks (The Fluorite System)
From translator's abstract: "The formation of fluorite in sedimentary rocks has been investigated by studies of fluorite equilibria in different solutions. Determinations at different temperatures were made on the solubility of crystalline CaF2 in chemically pure water, in aqueous solutions of components of seat water...at different concentrations, and in the sea water itself at degrees of salinity varying from normal to a 15-fold concentration."
