Radioactive waste requires significant isolation from the biosphere. Shallow land burial using low-permeability covers are often used to prevent the release of impounded material. This report details the characterization of a soil mixture intended for use as the low-permeability component of a radioactive waste disposal site. The addition of 6.5 percent bentonite to the sandy soils of the site reduced the value of saturated hydraulic conductivity (K{sub s}) by more than two orders of magnitude to 7.6 {times} 10{minus}{sup 8} cm/sec. Characterization of the soil mixture included measurements of grain density, grain size distribution, compaction, porosity, dry bulk density, shear strength, desiccation shrinkage, K{sub s}, vapor conductivity, air permeability, the characteristic water retention function, and unsaturated hydraulic conductivity by both experimental and numerical estimation methods. The ability of the soil layer to limit infiltration in a simulated application was estimated in a one-dimensional model of a landfill cover.

Crystal Field in Montcalm County, MI, was selected as a field trial site for this project. Analysis of production data for Crystal Field suggests that an additional 200,000 bbls of oil can be produced using one strategically located horizontal well. Total addition production from the Crystal Field could be as much as 6--8 MMBO. Application of the technology developed in this project to other Dundee fields in the area has the potential to increase Dundee production in Michigan by 35%, adding 80--100 MMBO to ultimate recovery. This project will demonstrate through a field trial that horizontal wells can be substantially increase oil production in older reservoirs that are at or near their economic limit. To maximize the potential of the horizontal well and to ensure that a comprehensive evaluation can be made, extensive reservoir characterization will be performed. In addition to the proposed field trial at Crystal Field, 29 additional Dundee fields in a seven-county area have been selected for study in the reservoir characterization portion of this project.

This document contains papers presented at the Fuel Cells `95` Review Meeting. Topics included solid oxide fuel cells; DOE`s transportation program; ARPA advanced fuel cell development; molten carbonate fuel cells; and papers presented at a poster session. Individual papers have been processed separately for the U.S. DOE databases.

Performance assessment models typically account for the processes of sorption and dissolution-precipitation by using an empirical distribution coefficient, commonly referred to as K{sub d} that combines the effects of all chemical reactions between solid and aqueous phases. In recent years, however, there has been an increasing awareness that performance assessments based solely on empirically based K{sub d} models may be incomplete, particularly for applications involving radionuclides having sorption and solubility properties that are sensitive to variations in the in-situ chemical environment. To accommodate variations in the in-situ chemical environment, and to assess its impact on radionuclide mobility, it is necessary to model radionuclide release, transport, and chemical processes in a coupled fashion. This modeling has been done and incorporated into the two-dimensional, finite-element, computer code BLT-EC (Breach, Leach, Transport, Equilibrium Chemistry). BLT-EC is capable of predicting container degradation, waste-form leaching, and advective-dispersive, multispecies, solute transport. BLT-EC accounts for retardation directly by modeling the chemical processes of complexation, sorption, dissolution-precipitation, ion-exchange, and oxidation-reduction reactions. In this report we: (1) present a detailed description of the various physical and chemical processes that control the release and migration of radionuclides from shallow land LLW disposal facilities; (2) formulate the mathematical models that represent …

Under investigation in this study was the effect of ASE certification of automotive technician training programs and other selected factors on ASE test outcome and job placement rate. This research ponders whether the time and money invested in certifying technician training programs is returning desired improvements in this automobile manufacturer's dealer service staff. The study focussed on technicians employed at Chrysler dealerships around the United States. The 2 samples totalling 387 males between the ages of 22 and 30 were drawn from 1,007 graduates of automotive technician training programs. Technicians that completed a formal training program beyond the high school level certified by the National Institute for Automotive Service Excellence (ASE) were compared to others whose training was not certified by ASE. Comparisons were made on the basis of ASE Automobile Technician Test scores and on the length of time from training program completion to employment. This research sought to identify the significance of association between three main predictors - the status of training program ASE certification, work experience and year of training program completion - and the most desirable levels of ASE test outcome (at or above 90% on the ASE test) and job placement rate (immediately following completion …

Laboratory experiments were conducted to evaluate the sorptivity of cesium onto Los Alamos soils under controlled experimental conditions. Four soil profiles were collected and each soil profile which is broken into layers according to previously identified soil horizons were studied. Batch sorption isotherms were studied to quantify the chemical reactivity of each soil horizon toward cesium ion. Radioactive cesium-137 was used as sorbent and gamma counting was used to quantify the amount of sorption. Desorption experiments were conducted after the sorption experiments. Batch desorption isotherms were studied to quantify the desorption of presorbed cesium from these Los Alamos soils. This study suggests cesium may sorb strongly and irreversibly on most Los Alamos soils. The amount of cesium sorption and desorption is possibly related to the clay content of the soil sample since subsurface sample has a higher clay content than that of surface sample.

This workshop dealt with engineering aspects and material properties of silicon electronic devices. Crystalline silicon growth, modeling, and properties are discussed in general and as applied to solar cells. Topics considered in discussions of silicon growth include: casting, string ribbons, Al backside contacts, ion implantation, gettering, passivation, and ultrasound treatments. Properties studies include: Electronic properties of defects and impurities, dopant and carrier concentrations, structure and bonding, nitrogen effects, degradation of bulk diffusion length, and recombination parameters. Individual papers from the workshop are indexed separately on the Energy Data Bases.

There are conflicting data in the literature regarding the effects of mirror exposure on subjective body-image evaluation. Much of the objective self-awareness research by Duval and Wicklund concluded that the presence of a mirror leads people to evaluate themselves negatively, while other studies have reported contrary findings. The primary purpose of this study was to determine the effects of mirror confrontation on individuals' body image ratings. Subjects were 88 childless, female university students. Using the Eating Disorders Inventory-Body Dissatisfaction subscale (BDS) as a screener, subjects were assigned to either a High Satisfaction group or a Low Satisfaction group. The subjects then completed the Multidimensional Body-Self Relations Questionnaire (MBSRQ) in either a Mirror or No Mirror condition. Results suggest that the presence of the mirror had no measurable effect on the subjects' ratings of themselves on the MBSRQ. There was a main effect for satisfaction level, and no interaction was found between the satisfaction level and the mirror condition. Possible explanations for these findings are offered.

This thesis investigates, analyzes, and discusses Picasso's imagery in the cultural context of the nineteenth-century Spanish tradition of flamenco. Two published photographs featuring the elderly artist with the gypsy guitarist Manitas de Plata initiated the study, and led me to the conclusion that selected works by Picasso were influenced psychologically, thematically, and formally by his youth which was spent in the Andalusian province of Malaga and later in Barcelona. Picasso's early artistic education occurred at precisely the same time and place as The Golden Age of Flamenco in Spain, a cultural phenomenon that profoundly affected both his life and art.
