The Reactivity of Uranium and Blacosolv
Abstract: "Blacosolv, trichloroethylene, is used in degreasing uranium metal. Tests were made under possible industrial conditions to determine whether a hazardous reaction between uranium and Blacosolv could occur. Temperature-rise measurements showed that there was no reaction of the metal, in various states of subdivision, with Blacosolv at temperatures up to 850 F. However, a reaction was observed in tests under which the finely divided metal, wet with solvent, was subjected to a severe impact."

A Study of Internal Friction and Twin-Boundary Movement in Uranium
From abstract: "The internal friction of recrystallized uranium has been shown to depend directly on heating and cooling rates and on the rate of application or removal of an external stress during measurement. At zero heating or stress rate, the internal friction falls to a low value and appears to decrease indefinitely at room temperature. Micrographs showing twin disappearance on removal or reversal of load are shown...It is concluded that the various internal-friction phenomena are the result of the stress-induced motion of twin boundaries." Results are compared with similar studies as well.

The Angular Dependence of Thermal Neutron Spectra in Lattices
This technical report discusses techniques that have been developed for "computing the angular thermal flux spectrum emerging from a lattice. These methods are applied to water lattices and it is found that the computed spectra are sensitive to the geometrical description of the lattice, but insensitive to the anisotropic scattering by water. Comparisons with measured spectra indicate that corrections for gradients and the finite size of the experimental lattice are important." -- from abstract (p. 3).

Determination of Diffusion Cooling in Graphite by Measurement of the Average Neutron Velocity
From Abstract: "The diffusion cooling coefficient in graphite has been determined by measuring the change in the asymptotic average velocity with buckling, by pulsed neutron methods. The times necessary to establish equilibrium spectra in graphite and heavy water have been measured and are reported."

The Reaction Between Hydrogen and Oxygen by Catalysis and the Thermal Reaction
From abstract: "The reaction between hydrogen and oxygen with the aid of various catalysts (especially platinum on aluminua) has been studied, and the operating variables such as flow rates, space velocity, temperature, and gas composition have been examined rather extensively. It has been found that hydrogen and oxygen in stoichiometric proportions and mixed with either steam or helium may be made to react to the extent of 99.5% or greater at space velocities up to 30,000 hr-1, or even higher, at temperatures from 100[degrees] to 900[degrees]C, and with mixtures ranging from less than 1% hydrogen to mixtures containing 12% hydrogen and 6% oxygen. Richer mixtures, including undiluted electrolytic gas (H2 + 1/2 O2) have been used with catalysts less active than platinum (e.g. copper, silver, nickel and V2O5) but here the gas mixture is explosive and care must be taken to prevent explosions. The thermal reaction between hydrogen and oxygen diluted with steam has also been investigated at temperatures between 500[degrees] and 800[degrees]C."

Excitation Functions for Reactions of Bev Protons on Indium (Master's Thesis)
Abstract: "Indium was bombarded with protons in the energy range 2 to 6 Bev. Cross sections are reported for the (p,px+), (p,pn), and (p,p') reactions, as well as those for the formation of Be-7 and several neutron deficient isotopes of cadmium and indium. It was found that the (p,pn) yield increases slowly in the energy range 2 to 6 Bev, while the (p,px+) and (p,p') yields are approximately constant. The variation of the (p,pn) and (p,px+) yields with target thickness is discussed. The yields of several isomeric levels are correlated with their nuclear spin."

Off-Gas Treatment in Berkeley Enclosures
"In the past ten years quantities of alpha-, beta-, gamma- and neutron-emitting isotopes handled in enclosures have increased from microcuries to kilocuries. Contaminated-atmosphere problems have increased accordingly. Developments at Berkeley are reviewed with particular emphasis on recent equipment, viz: a multiple-purpose gas scrubber and a total-capture system for slug-dissolver off gas."
