Preliminary Report on Some Uranium Deposits Along the West Side of the San Rafael Swell, Emery County, Utah
From introduction: Twelve uranium-bearing deposits were examined along 30 miles of the western border of the San Rafael Swell in Emery County, Utah, from September 21 to 29, 1950. The area examined lies in Emery County, east-central Utah, along the west flank of the San Rafael anticline (Fig. 1).

Neutron Yield in Uranium vs. Energy of Deuterons and Protons
The purpose of this note is to recalculate the semi-empirical curve of neutron yield vs. deuteron energy originally obtained by H. York in order to predict, using it and the best available data, what yields may be expected for deuterons on uranium in the extrapolated energy region.

The Preparation and Properties of Mammalian Ribonucleic Acids
"A method for the preparation of mammalian ribonucleic acids employing high concentrations of guanidine hydrochloride in the fractionation procedure is reported in this paper. Aside from the facility of preparation the method has the advantage of avoiding conditions of acidity and alkalinity which might degrade tissue ribonucleic acids and, by virtue of the protein denaturant action of guanidine salts, of minimizing the possibility for enzymatic degradation" (p. 3).

Heat of Reaction of Chlorine Trifluoride with Water
Abstract: "A measurement of the heat liberated when chlorine trifluoride reacts with water has been made in a simple Dewar calorimeter. The chlorine trifluoride vapor was bubbled into approximately 20 moles of water; the weight of material used, heat equivalent of the calorimeter, and the temperature rise of the water and calorimeter were determined. From these data an average value for the heat of reaction was calculated to be 81.0 +/- 0.4 kcal/mole. Analysis of the reaction solution and evolved gas showed the following to be present: hydrogen fluoride, hydrogen chloride, chlorine, oxygen, and probably oxygen-chlorine compounds."

Uranium Deposits on Mesas I 1/2 and II 1/2, Lukachukai Mountains, Northeast Arizona
Abstract: Mesas 1 1/2 and II 1/2 were investigated in October 1951, to determine the extent and degree of uranium mineralization in the Salt Wash sandstone. Carnotite-vanoxite-type minerals are sufficiently concentrated to recommend 14,600 feet of drilling.

Application of Heavy Media Separation, Flotation and Carbonate Leaching to Congo Ores
The investigation of magnesitic-dolomite uranium ores from Union Miniere du Haute Katanga, Belgian Congo, was undertaken in order to examine the possibility of separating the uranium minerals from the carbonate minerals by Heavy Media Separation or froth flotation; thus reducing the sulfuric acid consumption during the uranium leach. In addition, the effect of carbonate leaching the whole ore and carbonate flotation products was examined.

Recovery of Uranium From Congo Leach Liquors With Ion Exchange Resins
A method is described for recovery of uranium from sulfuric acid leach liquors of Congo ores using anion exchange resins. Excellent uranium recoveries were obtained in cyclic tests which indicate uranium capacities of 11 to 26 lbs. of U3O8 per cubic foot of resin per day. Preliminary tests indicate that sulfuric acid may be as effective as hydrochloric acid in providing the required acidity in the eluant.

Radiation of Pu²⁴³
"The radiations of Pu²⁴³ were studied with beta and gamma scintillation spectrometers alone and in coincidence. An incomplete disintegration scheme is deduced which leads to a total beta disintegration energy of 560 kev. A half-life of 4.98 ± 0.02 hours was observed."

Total Cross Sections of Tritium, Hydrogen, and Helium for Fast Neutrons
Abstract: "By using gaseous samples in neutron transmission experiments the total cross section of tritium has been measured over the energy region from 0.3 to 7.0 Mev and at the following additional energies: 14.1, 18.0, 19.1, and 20.0 Mev. A plot of cross section versus neutron energy shows a broad maximum with the greatest value of 2.5 barns at 3.7 Mev. Cross sections for helium were measured in the energy region from 1 to 3 Mev and for both hydrogen and helium at 14.1 Mev."
