Application of Heavy Media Separation, Flotation and Carbonate Leaching to Congo Ores

Description: 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

Description: 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.

Boundary Disturbances in High Explosive Shock Tubes

Description: Abstract: High Velocity disturbance are observed to propagate in advance of the plane shock front along the walls of a high-explosive-operated shock tube. Experiments were performed which indicate that the disturbance proceeds at a constant velocity relative to the shock front, and carries a considerable amount of energy as evidenced by its ability to penetrate metal plates. The velocity of a similar disturbance observed along a rod placed on the axis of the shock tube normal to the plane shoc… more

The Intracavitary Administration of AU 198

Description: At the Cancer Research Institute of the New England Deaconess Hospital radioactive colloidal gold has been given solely by the intracavitary route. To date 25 patients have been treated. These have been of two types: (a) patients with recurrent fluid formation of cardiocentesis in the pleural or peritoneal cavities; (b) patients with cardiocentesis of the lung in whom radiogold has been instilled post-operatively into the empty hemithorax. The use of AU198 in the first group of cases is now w… more

Nuclear Magnetic Resonance Project. Progress Report for March 15, 1951 to September 1, 1951. Steady State Transients in Nuclear Resonance and the Nuclear Relaxation time. T2, for Hydrocarbons

Description: The Bloch formulation of Nuclear Magnetic Resonance is applied to a repeated pulsing of the external electromagnetic field H1. The steady-state solution is shown to predict the existence of sidebands, a mirror signal, and magnetic field inhomogeneity effects. All of these effects ae shown to be verified experimentally, thus strengthening the ap0plicibility of the Block formulation to transient problems. The solution given was used to determine T2 from the observed transient signals for liquid h… more

Nuclear Magnetic Resonance Project. Progress Report III for 1 September 1951 to 15 March, 1952. Determination of the Accuracy of the Infinitely Repeated Pulse Method and the Observed Effects of Molecular Self Diffusion in Liquids

Description: The range of measurements of nuclear magnetic resonance by the infinitely repeated pulse method is higher than the slow passage method of Bloch. As the measurements approach 10-1 seconds the effect of viscosity or self diffusions becomes important. For liquid hydrocarbons this effect is such as to make the previously measured values for liquid hydrocarbons subject to severe revision. Several possibilities have recently become apparent for making this improvement.

Structural Alterations in the Tissue Sections Associated with Embedding Following Freeze Drying

Description: Various types of tissue distortion and structural artifacts which occur in stained microscopic tissue sections are usually referred to as "fixation artifacts." These include, among other effects, shrinkage of cells (e.g. crenation of red cells, shrinkage of blood plasma away from vessel walls, and shrinkage of groups of cells producing microscopic empty spaces between structures within the tissue section. On the other hand, swelling and even rupture of cells (e.g. homolysis of red cells) is al… more

Thiomethyladenosine

Description: The mechanism of thiomethyladenosine accumulation in yeast was studied by attempting to substitute homocysteine methylmercaptane methylmercaptoethanol and methylome captopropionaldehyde for methionine as a specific precursor. Negative results militate against transmethylation as the underlying mechanism. Tracer studies with methyl-C14- and and S35-labeled methionine suggest transthiomethylation with intermediate formation of a thetin-like compound tentatively termed methionyladenosine. The occu… more

Final Status Report on the Positive Excess of Cosmic Ray Mesons

Description: This experiment was undertaken to study the radiative Bohr orbit transitions of stopped negative mesons in absorbers of high and intermediate Z. (These transitions occur substantially instantaneously, ie in the time taken for the meson to make the transition to its K orbit as opposed to the delayed radiation which occurs after the meson in its K orbit interacts with the nucleus).

Interpretation and Evaluation of the Uranium Occurences Near Goodsprings, Nevada: Final Report

Description: Abstract: The uranium occurrences near Goodsprings, Clark Co., Nevada, are divided into two distinct types which differ from each other in geographic distribution, localization of mineralization, mineralogy and origin. None of the known deposits is of present commercial significance and therefore this study emphasizes the genetic rather than the economic aspects.

Infrared Spectra and Structure of the Crystalline Sodium Acetate Complexes of U(VI), Np(VI), Pu(VI), and Am(VI). A Comparison of Metal-Oxygen Bond Distance and Bond fFrce Constant in this Series

Description: Infrared spectra of solid NaXO2(Ac)3, with X=U, Np, Pu, and Am, have been observed. From the symmetric and asymmetric stretching frequencies of the O-X-O groups, approximate X-O force constants have been calculated and were found to decrease in the order kU—O>kNp—O>kPu—O> kAm—O, the respective values being about 0.705, 0.698, 0.675, and 0.612 megadyne/cm. From the cell constants for NaXO2(Ac)3 it is apparent that the X-O bond distance decreases in the same order—RU—O>RNp—O>RPu—O>RAm—O. Thus, a … more
