Abstract: "The ductility of Type 310 stainless steel T-joints brazed with GE-62 brazing alloy was measured at room temperatures 1200, 1650, and 1800 F. The measure of ductility was taken as the plastic axial strain required to crack braze fillets in T-section tensile specimens. At elevated temperatures, the ductility of as-brazed joints approximated that of the stainless steel, but at room temperature the brazed joints had only one-tenth the ductility of the base metal. Annealing for 16 hr at 1800 F in air was found to triple the room-temperature ductility of the brazed joint."

"The previously found maximum in the cosmic radiation energy spectrum is discussed, and the possibility that it arises in part from a misinterpretation of the data due to oversimplifying assumptions about the composition of the beam is examined. The importance that lack of recognition of isotopic composition may have is pointed out, and it is clear that this importance is strongly dependent on the measurements made and on the cut-off rigidity."

As previously reported, zirconium undergoes large dimensional increases after scaling in air in a critical temperature range, 700 degree-1050 degree C. This finding was observed with specimens of a constant thickness (0;062 in.) To study the thickness effect, a number of specimens ranging in thickness from 0.020 to 0.200 in. were scaled in air at a temperature (900 degree C) where the growth is a maximum for a given time. Both cold rolled iodine sheet and forged iodide bar stock were used. to determine the effect of orientation, specimens from the forged bar were obtained such that the scaling surface was either parallel to or perpendicular to the long axis of the bar.

The following report is divided into two parts, both parts center around the effects of radiation on skin tissue. Part one focuses on superficial radiation, or Beta rays, while part two is on penetrating radiation, or neutrons and gamma rays.

Abstract: "The potential of the Np(IV)-Np(V) couple is not directly measurement since the couple does not establish reversible equilibrium at an inert electrode. Reproducible potential measurements were obtainable, however, in solutions containing Np(IV), Np(V), Pe(II), and Pe(III) ions in oxidation-reduction equilibrium. The expected fourth power hydrogen ion dependence of the Np(IV)-Np(V) couple was confirmed over the range 0.25-1.0 molar perchloric acid concentration. The heat of the reaction NpO2+ + 1/2 H2 + 3H+ = Np-(+4) + 2 H2O in 1 molar perchloric acid solution was determined from the electromotive force temperature coefficient to be -36.3 +/- 0.3 kg.-cal. The formal potential of the Np(IV)-Np(V) couple is -0.746 v. at 25 degrees in 1 molar perchloric acid solution."

Abstract: "Preliminary data have been taken to evaluate X-ray absorption at the L III edge of uranium as a method of detection of uranium in solution. Uranium concentrations in water from 150 ppm to 30,000 ppm have been investigated. The effect of copper as a typical contaminant in the range of 737 ppm of copper to 36,850 ppm of copper has been investigated for a representative uranium solution. Instrumentation has been constantly improved and suggestions for further improvements in amplifying and counting equipment are included. Comparison of experimental data with theory indicates that the derived equations are adequate."

Abstract: A TEC regulator amplifier driving an Eaterline-Angus recording meter was used to record magnet current variations. Tests were made to determine magnet current variations. Tests were made to determine magnet current stability for currents from 500 amperes to 4000 amperes. Changes were necessary in both the TEC and GE regulators before currents below 2500 amperes could be regulated. Regulation to 0.025 percent for and hour was obtained for currents of 1000 to 4000 amperes with the TEC and GE regulators, and regulation to 0.05 percent for 500 ampere currents.

This is a progress report compiled by the chemical development department of the Carbide and Carbon Chemicals Corporation's Y-12 plant, discussing work on the carbonate (Monticello) process, as well as the recovery of uranium and vanadium from carbonate liquors.

The [beta] spectrum of the 10-year Pu²⁴¹ was run on a sample of radiochemically pure plutonium containing the isotopes Pu²³⁹, Pu²⁴⁰, Pu²⁴¹, isotopically enriched in Pu²⁴¹ by pile neutron irradiation. The isotopic composition was determined mass spectrographically.

This report follows an investigation with the purpose of studying the operational characteristics of a catalytic tube recombiner where the gases are passed over stainless steel tubes coated with platinum black.

"Graft polymers were made by Co60 mutual irradiation of mixtures of styrene and methyl acrylate in contact Teflon. These graft copolymers were analyzed by infra-red absorption and their composition determined. The composition of the graft copolymer formed from styrene and methyl acrylate was different from that which is predicted by the copolymer composition equation."
