Micelle-derived catalysts for extended Schulz-Flory. Technical progress report, October 1, 1985--12/31/85

Our objective is to develop a catalyst for making gasoline or diesel range fuel selectively from synthesis gas. Our catalyst development approach is to provide a cut-off for the higher end of the hydrocarbon distribution by limiting the size of the active metal particle. We are using a micelle technique for preparing specific size ruthenium particles supported on {gamma}-alumina. Hydrocarbon cut-off was not observed with 40--60 {Angstrom} ruthenium particles on {gamma}-alumina. We could not determine whether smaller ruthenium particles would provide cut-off since they agglomerated during the test, apparently through the formation of ruthenium carbonyl. In order to determine whether ruthenium migration can be eliminated under a new set of testing conditions, we evaluated the effect of H{sub 2}:CO feed gas ratio and the effect of total pressure on ruthenium migration. Ruthenium migration was significantly suppressed but not totally eliminated by increasing the H{sub 2}:CO feed gas ratio from 0.9 to 3.0. At the same H{sub 2}:CO feed gas ratio, lowering the total pressure from 500 psig to 150 psig enhanced ruthenium migration. During the next quarter, the use of high pressure in conjunction with high H{sub 2}:CO feed gas ratio will be evaluated to eliminate ruthenium migration. In case …

Children of Battered Women: Personality Patterns and Identification

Mental health professionals have observed that children who witness interparental violence frequently display either an affrontive, demanding personality style, or a passive, compliant style. The prevalence of these personality types and their relation to identification, stress, and other variables was evaluated in a sample of 40 children (age range = 6 - 12 years old) who have witnessed parental spouse abuse. Children completed the Children's Personality Questionnaire and the Parental Identification Questionnaire. Mothers completed the Life Experiences Survey. Independent ratings of the children's personality were made. The results validated the existence of these two personality styles among both male and female witnesses, and supplied evidence for their relation to paternal identification, familial instability, and parental ineffectualness. The implications of these findings for assessment and intervention are discussed.

An Investigation of Factors Deterring Participation in Continuing Professional Education

This study was conceived as an attempt to determine .and analyze factors deterring participation in continuing professional education among social workers in environments where continuing education for relicensure is mandatory and voluntary. The specific research design implemented to complete this study was the ex-post facto descriptive design. The sample included 106 social workers randomly selected in the state of Texas where continuing education is mandatory and 94 social workers in the state of Louisiana where continuing education is voluntary. The instrument used was the Deterrent to Participation Scale developed by Scanlan (1983) and a demographic inventory. Scanlan (1983) earlier identified six factors deterring participation in continuing professional education: Disengagement, Lack of Quality, Family Constraints, Cost, Lack of Benefit, and Work Constraints. The study concluded that social workers in both states considered work constraint as a major factor deterring participation in continuing professional education. Also the factors of cost and lack of quality were also considered as crucial barriers in their efforts to participate in continuing professional education. The Wilks' multivariate test of significance of the means and univariate F tests at alpha level p < .05 revealed differences in the combined mean scores of social workers in both states when …

Childrearing Attitudes of Mexican-American Mothers Effects of Education of Mother

The purpose of this study was to identify childrearing attitudes of Mexican-American mothers with children ages three to five years of age. Specifically the first purpose of this study was to determine childrearing attitudes of Mexican-American mothers with ten years of education or fewer and Mexican-American mothers with eleven years of education or more as identified by the Parent As A Teacher Inventory (PAAT). The second purpose was to identify the relationship of the following demographic variables to childrearing attitudes: mother's age, mother's marital status, family income, sex of child, age of child, access to child, generational status, mother's language and mother's ethnicity. The PAAT and the Parent Information Questionnaire were administered to 112 Mexican-American mothers; 54 Mexican- American mothers with ten years of education or fewer and 58 Mexican-American mothers with eleven years of education or more. The population from which these subjects were drawn were mothers from Mexican-American communities in a North Texas county. Responses on the sample were analyzed using multivariate statistics. Based on the analysis of the data, the following conclusions seem tenable. 1. The Mexican-American mothers with eleven years of education or more have childrearing attitudes which are more positive than the Mexican-American mothers with …

PSP Program close out documentation

In December 1982 DOE-SR directed SRL to study the feasibility and impact of a program to lower the U-236 content of the Highly Enriched Uranium (HEU) stockpile used as fuel for the SRP reactors. In response to this request SRL assessed four technologies, Atomic Vapor Laser Isotope Separation (AVLIS), Molecular Laser Isotope Separation (MLIS), Gas Centrifuge, and the Plasma Separation Process (PSP) for this purpose with the assistance of the Engineering Department. In April 1983 cost/benefit analyses for these processes, high spot cost estimates for production facilities, and process uncertainties were submitted to DOE-SR with a recommendation to proceed with the conceptual design and supporting development programs for a facility based on the use of the PSP process. The current program status for the PSP development program at SRL and the design and documentation of a production facility at SRP, referred to as the Fuel Improvement Demonstration Facility (FIDF), is described in this report.

Historical Estimates of External Gamma Exposure and Collective External Gamma Exposure from Testing at the Nevada Test Site. I. Test Series through HARDTACK II, 1958

In 1959, the Test Manager's Committee to Establish Fallout Doses calculated estimated external gamma exposure at populated locations based upon measurements of external gamma-exposure rate. Using these calculations and estimates of population, we have tabulated the collective estimated external gamma exposures for communities within established fallout patterns. The total collective estimated external gamma exposure is 85,000 person-R. The greatest collective exposures occurred in three general areas: Saint George, Utah; Ely, Nevada; and Las Vegas, Nevada. Three events, HARRY (May 19, 1953), BEE (March 22, 1955), and SMOKY (August 31, 1957), accounted for over half of the total collective estimated external gamma exposure. The bases of the calculational models for external gamma exposure of ''infinite exposure,'' ''estimated exposure,'' and ''one year effective biological exposure'' are explained. 4 figs., 7 tabs.
