Rubber Hydrochloride Film as a Replacement for Nylon Film for Radiation Detection Detecting Instruments. Technical Memorandum No. 5-52-15

Description: Air filled proportional or ionization type alpha radiation detecting instruments are usually covered on the open face with a thin conductive film of material. due to the low penetrating ability of alpha particles, it is essential that the film be extremely thin and hence quite fragile. A determination of certain properties of rubber hydrochloride film indicated that it possesses advantages over nylon film which is presently used. Rubber hydrochloride is more resistant to puncture, easily decont… more

Duration of Post-Irradiation Bacteremia in Mice

Description: Mice exposed to moderate does of total body x-radiation have been found to develop septicemias during the second week post-irradiation. The micro-organisms causing these generalized infections were all members of normal intestinal flora. The results of our experiments confirm those obtained on mice killed at daily intervals post-irradiation. Septicemia is a prominent manifestation or irradiation injury the second week post-irradiation in mice exposed to moderate does of x-ray. These results sho… more

The Gram-Negative Flora of the Upper Intestinal Tract and Its Influence on Post-Irradiation Bacteremia in Mice

Description: A systematic study of the flora of the intestinal tract of mice exposed to 550 r of total body x radiation showed an increase in all the Gram negative bacilli in the upper half of the small bowel about the end of the first week post irradiation. When the flora of the gut was changed artificially by introducing about 10 Pseudomonas aeruginosa the effect produced increased with the lapse of time after exposure to irradiation. The sharpest rise in mortality due to Pseudo monas bacteremia occurred … more

Average Charge of Daughter Atoms After Beta Decay

Description: Chemical effects follow beta decay have recently been noted. In each case an increase in oxidation state of the daughter atom has been observed. The results of the studies thus far indicate that orbital electron loss accompanying beta decay is negligible.

Density Transients in Boiling Liquid Systems. Report 52-17.

Description: A program was undertaken to study the density response of a liquid-vapor system when subjected to a change in the magnitude of a distributed heat source. The density transients would be caused by the initiation, growth, and collapse of the vapor bubbles and by their travel into or out of the specified volume. The program is both analytical and experimental and the end objectives are as follows: (1) to obtain a record of the density transient associated with a change in distributed volume heatin… 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

A Semi-Quantitative Study of the Effects of Radiophosphorus on the Spleen of the Cotton Rat, Sigmodon Hispidus Texianus

Description: Following the intraperitoneal injection of 50 με of P32 the spleens of rats were examined microscopically at time intervals of 1 to 63 days and quantitative counts of the cellular constituents were made. Changes in splenic tissue observed included thinning of the stroma and nuclear disorganization in occasional cells, shifts in the relative quantities of the various splenic cellular constituents, notably the reduction in number of some of the more radiosensitive cellular elements, and the compe… more

The Metabolism of Radioactive Vitamin B12 by the Ruminant

Description: Radio-vitamin B12 excretion by the ruminant has been investigated following both oral and intramuscular administration to two young dairy calves. The results obtained indicated that the vitamin is retained to a much greater extent when given by subcutaneous injection than when given orally. This is in contract to previous work with the rat, where the amounts retained were similar, although the pathway of excretion was different.

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.

Sodium-Air Accident Study for a Sodium Cooled Reactor. Technical Memorandum No. 20

Description: The design requirements of a containment building for a sodium-cooled reactor have been investigated from the point of view of a hypothetical sodium - air reaction. In particular, this study was directed toward the containment building of the Enrico Fermi Atomic Power Plant. The hypothetical accident assumes a major leak in the sodium system with a concurrent or earlier failure of the ventilation and cooling systems which allows air to enter the areas around the sodium system which are normally… more

Description: The purpose of the test was to determine the effect of continuous air pressurization of the Valve Operating System water flask on the the oxygen concentration of the water in the flask. Oxygen concentration in the Valve Operating System water flask increased during the testing period of seventeen days. It cannot be determined from the data obtained if equilibrium oxygen concentration was reached. The distribution of oxygen in the flask at the end of 17 days varied from approximately 12 ppm in t… more

A 704 Program for Computing Thermal Neutron Spectra in Infinite Homogenous Media

Description: A flexible program has been prepared for solution of the neutron balance equation in an infinite homogeneous medium. This program is specifically designed for studying the effects of varying the energy transfer kernel on the resultant neutron spectrum. A rapidly converging iterative procedure is employed. The equation to be solved and the specific input information required by the program in order to compute spectra are explicitly stated. No discussion of the physics of the problem is given.
