Effects of Gold Sodium Thiomalate on Murine Spleen Cells
The effects of gold sodium thiomalate (GST) on murine spleen cells were investigated using in vitro mitogen blastogenesis techniques. Addition of GST to intact spleen cells resulted in a decreased blastogenic response to the T cell mitogen, concanavalin A (Con A). Thymidine uptake of spleen cells depleted of macrophages and cultured with Con A and GST demonstrated biphasic effects. At 2.5 pg Con A/ml, blastogenesis of macrophage depleted spleen cells was inhibited to a lesser degree than intact spleen cells; whereas, at 0.5 pg Con A/ml, the macrophage depleted spleen cells were inhibited to a greater degree than the intact spleen cells. Addition of GST at intervals ranging from 0 to 48 hours indicated that inhibition occurred within 36 hours following mitogen stimulation. These results suggest that GST inhibits early events of lymphocyte activation by direct interaction with lymphocytes.

(Restriction of virus infection by plants: Annual report, 1986)
This research concerns the strong resistance, or even immunity, against a specific virus that is exhibited by one or a few lines of a plant species, in contrast to the general susceptibility of most lines of that species. The contrast between the reactions to virus inoculation of different lines of one species implies that a single gene or a very few genes may mediate the resistance or immunity. The prospects for isolating, studying and transferring such a gene should be good for a system with these characteristics. Seedlings of a line Arlington of the cowpea (Vigna unguiculata) fail to support the replication of cowpea mosaic virus strain SB (CPMV-SB). Genetic crosses of Arlington cowpea to the systemic host Blackeye 5 cowpea show that the immunity is inherited as a simple dominant gene. In contrast to the seedlings, the protoplasts of the Arlington cowpea support CPMV-SB replication, but only to a very low level compared to protoplasts of Blackeye 5 cowpeas. From evidence reported earlier we concluded that Arlington cowpea protoplasts restrict the production of CPMV-SB proteins. We postulated, and obtained evidence for, a proteinase inhibitor that is specific for a CPMV-SB proteinase. This proteinase inhibitor is our prime candidate for …

Shock wave interaction with turbulence: Pseudospectral simulations
Shock waves amplify pre-existing turbulence. Shock tube and shock wave boundary layer interaction experiments provide qualitative confirmation. However, shock pressure, temperature, and rapid transit complicate direct measurement. Computational simulations supplement the experimental data base and help isolate the mechanisms responsible. Simulations and experiments, particularly under reflected shock wave conditions, significantly influence material mixing. In these pseudospectral Navier-Stokes simulations the shock wave is treated as either a moving (tracked or fitted) domain boundary. The simulations assist development of code mix models. Shock Mach number and pre-existing turbulence intensity initially emerge as key parameters. 20 refs., 8 figs.

Customer System Efficiency Improvement Assessment: Description and examination of system characterization data
This report describes three data bases that were developed in the Customer System Efficiency Improvement (CSEI) Assessment project to help characterize transmission and distribution (T and D) system losses experienced by utility customers in the Pacific Northwest. A principal objective of this project is to assess the potential for electric energy conservation in the T and D systems of BPA's utility customers. The three data bases provide essential input on the number and operating characteristics of T and D component stocks that was used in another task of the CSEI Project to estimate the conservation supply functions that result from replacing existing stocks with more efficient components (Tepel et al. 1986). This document describes the three data bases, provides a guide to their use, and presents a summary characterization of the principal loss-generating components (lines and transformers) of the region's T and D systems.

Kriging for interpolation of sparse and irregularly distributed geologic data
For many geologic problems, subsurface observations are available only from a small number of irregularly distributed locations, for example from a handful of drill holes in the region of interest. These observations will be interpolated one way or another, for example by hand-drawn stratigraphic cross-sections, by trend-fitting techniques, or by simple averaging which ignores spatial correlation. In this paper we consider an interpolation technique for such situations which provides, in addition to point estimates, the error estimates which are lacking from other ad hoc methods. The proposed estimator is like a kriging estimator in form, but because direct estimation of the spatial covariance function is not possible the parameters of the estimator are selected by cross-validation. Its use in estimating subsurface stratigraphy at a candidate site for geologic waste repository provides an example.

Occurrence of fracture-lining manganese minerals in silicic tuffs, Yucca Mountain, Nevada, USA
Yucca Mountain, in southern Nevada, is being studied by the Nevada Nuclear Waste Storage Investigations (NNWSI) Project as a potential site for an underground high-level nuclear waste repository. The site is within Miocene volcanic rocks that are 1.5 to 4 km thick and range in age from 12.5 to 14 MY. Several holes have been drilled in Yucca Mountain for geologic and hydrologic studies. Drill hole USW G-4, the most recently cored hole within the potential repository block, was chosen for detailed study of fracture-filling minerals because it is closest to the planned NNWSI exploratory shaft. Drill hole USW G-4 was drilled to 914.7 m (3001 ft) and continuously cored from 6.7 m (22 ft) to total depth (TD). The drilling history, lithology of the core, and geophysical logs of the well were published earlier. Because manganese oxides in fractures may act as a natural barrier to radionuclide migration, it is important to determine exactly which manganese minerals are present, in what intervals they occur, and how extensive these fracture coatings are.

Simulation of uranium transport with variable temperature and oxidation potential: The computer program THCC (Thermo-Hydro-Chemical Coupling)
A simulator of reactive chemical transport has been constructed with the capabilities of treating variable temperatures and variable oxidation potentials within a single simulation. Homogeneous and heterogeneous chemical reactions are simulated at temperature-dependent equilibrium, and changes of oxidation states of multivalent elements can be simulated during transport. Chemical mass action relations for formation of complexes in the fluid phase are included explicitly within the partial differential equations of transport, and a special algorithm greatly simplifies treatment of reversible precipitation of solid phases. This approach allows direct solution of the complete set of governing equations for concentrations of all aqueous species and solids affected simultaneously by chemical and physical processes. Results of example simulations of transport, along a temperature gradient, of uranium solution species under conditions of varying pH and oxidation potential and with reversible precipitation of uraninite and coffinite are presented. The examples illustrate how inclusion of variable temperature and oxidation potential in numerical simulators can enhance understanding of the chemical mechanisms affecting migration of multivalent waste elements.

The Role of Assistant Principals in Large High Schools in Texas
The purpose of this study was to determine the role of high school assistant principals as perceived by principals, assistant principals, and teachers. The population in this study consisted of the principals, assistant principals, and teachers in Class 5A high schools in Texas during the 1985- 86 school year. One hundred and twenty of the Class 5A high schools were randomly selected to participate in the study. One principal, one assistant principal, and one teacher from each school were asked to respond to the survey. A questionnaire was designed to measure the perception of the three groups under study and contained seventy-seven job responsibilities which were divided into six major areas. The six areas were school management, staff personnel, community relations, student activities, curriculum and instruction, and pupil personnel. Eighteen items were eliminated through clarity, appropriateness, and reliability studies. Each respondent was asked to rate the degree of involvement of assistant principals for each job responsibility listed in two columns labeled current and ideal. Five hypotheses were developed for the study. Three hypotheses were tested by a multivariate one-way analysis of variance with repeated measures, and two were tested using a univariate one-way analysis of variance. The .05 level of …

The Relationship Between One Aspect of Morality of Young Children and Parental Attitudes Toward Child-Rearing, Gender, Employment Status and Socio-Economic Status
This study examined the relationship between the resistance to temptation of three-, four-, and five-year-old children and parental attitudes toward child-rearing. Other variables explored included gender of the children, employment status of mothers, and socio-economic status of families. Fifty-two three-, four-, and five-year-old children from two centers were tested to determine their levels of resistance to temptation as measured by Grinder's Bean Bag Instrument. Parental attitudes toward child-rearing were measured by Schaefer and Bell's Parental Attitude Research Instrument (PARI). To determine the difference between the resistance to temptation scores and socio-economic status, gender, and employment status of mothers, Jt tests were employed. No significant differences were found with regard to these variables. Factor analysis of the PARI resulted in three primary factors: Hostility-Rejection, Authoritarian- Control, and Democratic-Attitude. To determine the difference between the Hostility-Rejection scores, Authoritarian-Control scores, and Democratic-Attitude scores of the mothers and socio-economic status, _t tests were employed. There were no significant differences between mothers of a lower socio-economic level and their Hostility- Rejection and Democratic-Attitude scores. However, mothers of a lower/upper socio-economic level showed significantly higher levels of Authoritarian-Control than mothers of an upper socio-economic level. To determine the difference between the Hostility-Rejection scores, Authoritarian- Control scores, …
