Development of a rotational power loss measuring system based on the wattmeter method for a single Epstein strip and a brief discussion of magnetization processes of Si-Fe sheets under the rotational magnetizing condition are described. The pick-up coil system has a configuration with a flux search coil sandwiched by…
A ceramic electrolysis cell and a palladium diffuser have been developed in Japan and tested with tritium at the Tritium Systems Test Assembly (TSTA) at the Los Alamos National Laboratory, to test their feasibility as possible upgrades for the fuel cleanup system (FCU). The ceramic electrolysis cell, made of stabilize…

The parameters of gas-metal interaction solubility S, diffusivity D and permeability of protium and deuterium in stainless steel 316L have been determined in the temperature range from 600 to 900 K and in the pressure range from 102 to 105 Pa. The results can be presented by: where KS (Sieverts’ constant) is given in…
Basic characteristics of photomodulation spectroscopy are discussed. The method is applied to studying the band-tail states in a-Si:H and a-Ge:H, and the dangling-bond states in irradiated a-Si:H, trans-(CH)x, and chalcogenide glasses.
The new compounds Ca 3 GaAs 3 and Ca 3 InP 3 crystallize in the orthorhombic system, space group Pnma (No. 62) with the lattice constants Ca 3 GaAs 3 : a = 1217.1(5) pm, b = 419.7(2) pm, c = 1341.4(5) pm; Ca 3 InP 3 : a = 1201.9(5) pm, b = 413.8(2) pm, c = 1346.0(5) pm. In the structures distorted GaAs 4 - and InP 4 -…
Abstract The photoreactions of 2,4,6-triphenyl- (TPP), 2-t-butyl-4,6-diphenylpyrylium (2BDPP) and 2,4,6-triphenylthiopyrylium (TPTP) salts in tetrahydrofuran (THF) and/or 1,2-dimethoxyethane were investigated. Photoproducts were identified to be pyranyl radicals on the basis of photochemical behavior and ESR spectra.…
Abstract Graft copolymerization of maleic anhydride (MA) onto PVA was carried out both in the presence and absence of the initiator. In the former case, the resultant was a copolymer containing a carboxylic acid and a keto‐olefinic side chain. Therefore, the reaction product, viscosity, gel content, and mechanical pro…
Savannah River Laboratory is developing new technology to improve the safety, reliability, and flexibility of processing tritium at the Savannah River Plant. This technology, based on metal hydrides, will also decrease the equipment size. The LaNi5-xAlx series of alloys is used for tritium storage applications and pal…
The results of two types of experiments on electrochromic (poly)crystalline films of rf sputtered WO3 are presented as additional new evidence that the behavior (especially scattering) of the free electrons plays a dominant role in the electrochromic properties of such films.

The purpose of this study was to develop a multivariate method for structuring a sizing system for women's apparel. The I 977 suvey of U.S. Army women was the data base. The sample was limited to 1217 subjects who were White or Black and 17-3 5 years old. The methodology underlying PS 42-70, the current U.S. sizing st…
The electrochemical properties of solid films of Mt‐2,3,9,10,16,17,23,24‐octacyanophthalocyanine 2 were studied by cyclic voltammetry in aqueous electrolytes. The thin (10–100 nm) film electrodes show remarkably stable electrochromic redox behavior, and the charge exchanged in the cathodic and anodic waves, respective…

Three dimensions of human comfort with respect to clothing are proposed: physical, psychological, and social comfort. A pilot study of 60 women, aged 60 to 80, was conducted to develop and test a semantic differential measure of these three human comfort dimensions with respect to actual and ideal insulative clothing…
The changes in collagen metabolism during skeletal muscle growth were investigated by measuring rates of synthesis and degradation during stretch-induced hypertrophy of the anterior latissimus dorsi muscle of the adult chicken (Gallus domesticus). Synthesis rates were obtained from the uptake of tritiated proline inje…
A continuum model for dynamic tensile cleavage fracture and fragmentation has been developed for detailed simulation of brittle fracture processes in elastoplastic materials. The model includes processes for nucleation of microcracks, stress-dependent growth, coalescence and fragmentation, and stress relaxation caused…
