Nuclear Technology Programs semiannual progress report, April-- September 1990

Description: This document reports on the work done by the Nuclear Technology Programs of the Chemical Technology Division, Argonne National Laboratory, in the period April--September 1990. These programs involve R D in three areas: applied physical chemistry, separation science and technology, and nuclear waste management. The work in applied physical chemistry includes investigations into the processes that control the release and transport of fission products under accident-like conditions in a light wat… more

The Impact of Corporate Interlocks on Power and Constraint in the Telecommunications Industry

Description: Using the tools of structural and network analysis developed by Ronald R. Burt and others, this study investigated the communication patterns among corporate officers of American Telephone and Telegraph Corporation (A.T. & T.) and United Telecommunications Corporation (Sprint). Data on contacts, efficiency, network density, and constraint indicate that opportunities for power and constraint have remained relatively stable at United Telecommunications between 1980 and 1990. A. A.T. & T., on the … more

Changes in Heterozygosity Through Time in American Standardbred and American Saddlebred Horses (1960-1990)

Description: Observed and expected heterozygosity (H) levels for ten electrophoretic blood marker loci and expected H for seven red blood cell (RBC) anitgen/antibody loci were examined for 20 years in American Standardbred and 30 years in American Saddlebred horses. Standardbreds were classed by gait, Trotter and Pacer, and evaluated separately in most analyses. 4,404 Trotters and 12,271 Pacers were found to have statistically highly significant losses of mean total observed H through time for the ten elect… more

Social-structural and Election Level Determinants of the Outcome of Union Certification Elections, 1981-1990

Description: The purpose of this research is to identify major factors that can be used to explain and predict the process of growth in union membership as represented by union victories in certification elections. The emphasis of this research is on organization and social-structural level factors. The logistic regression procedure reveals that organization level variables are most significant in explaining union victories in certification elections. Among the organization level variables, Unit Size, as de… more

Photoinduced electron transfer reactions in zeolite cages. Progress report, January 15, 1990--August 1, 1992

Description: This report summarizes work in the two areas of zeolites and layered double hydroxides. Results of studies on structural aspects of Ru(bpy)[sub 3][sup 2+]-zeolite Y are summarized. Photoinduced electron transfer between entrapped Ru(bpy)[sub 3][sup 2+] and methylviologen (MV) in neighboring supercages was examined. Benzylviologen was also used. Since molecules larger than 13 [angstrom] cannot be accomodated in zeolite cages, the layered double metal hydroxides (LDH) LiAl[sub 2](OH)[sub 6][sup +… more

Novel concepts in weld science: Role of gradients and composite structure. Technical progress report, June 1, 1990--August 31, 1992

Description: The effects of compositional and microstructural gradients on weld metal properties were investigated. The effects of compositional gradients were analyzed using thermodynamic and composite models. Brittle and ductile cracking behavior were investigated using both binary alloy single crystals and large grain castings. In both cases, the crack propagated along regions where the compositional gradients were the steepest. High temperature deformation of large wavelength compositonally modulated st… more

Novel ways of depositing ZnTe films by a solution growth technique. Final subcontract report, 1 January 1990--1 January 1992

Description: An electrochemical process has been successfully developed for the reproducible deposition of ZnTe and copper-doped ZnTe films suitable as transparent ohmic contacts for CdS/CdTe solar cells. The development of this method and optimization of key processing steps in the fabrication of CdS/CdTe/ZnTe:Cu devices has allowed IEC to achieve cell performance results of FF>70% and {eta} {approximately}10%. Preliminary efforts have indicated that the deposition methods investigated are potentially feas… more

Effect of Fracture Surface Interference on Shear Crack Growth. Progress Report, September 1, 1990--April 30, 1992

Description: A joint analytical-experiment program to investigate the effect of fracture surface interference on shear modes of crack growth is progressing satisfactorily. A general two-dimensional, boundary element model has been formulated by the group at Ohio State University that is capable of calculating the effective Mode I and Mode II stress intensity factors for flat or curved cracks with small scale yielding. The model can calculate K{sub I} and K{sub II} for an arbitrary constitutive law for displ… more

Representations of Women in The Dallas Morning News During the Feminist Movement

Description: Content analysis of The Dallas Morning News focuses on sources, bylines, photographs, and main characters to determine the quantity and quality of portrayals of women. The study included front pages and main local news pages during one week each from 1950, 1960, 1970, 1980, and 1990. Change was charted by year for both sexes. In 1950, few representations of women were included and many were stereotypical. Some stereotyping persisted in 1990, and men outnumbered women more than 3 to 1 as story s… more
