3-D treatment of convective flow in the earth's mantle
A three-dimensional finite-element method is used to investigate thermal convection in the earth's mantle. The equations of motion are solved implicitly by means of a fast multigrid technique. The computational mesh for the spherical problem is derived from the regular icosahedron. The calculation described use a mesh with 43,554 nodes and 81,920 elements and were run on a Cray X. The earth's mantle is modeled as a thick spherical shell with isothermal, free-slip boundaries. The infinite Prandtl number problem is formulated in terms of pressure, density, absolute temperature, and velocity and assumes an isotropic Newtonian rheology. Solutions are obtained for Rayleigh numbers up to approximately 10/sup 6/ for a variety of modes of heating. Cases initialized with a temperature distribution with warmer temperatures beneath speading ridges and cooler temperatures beneath present subduction zones yield whole-mantle convection solutions with surface velocities that correlate well with currently observed plate velocities. 8 references, 6 figures.

5 K neutron irradiation and thermal cycling of NbTi superconductors
Simulation experiments of magnet operating conditions in a fusion reactor are reported. After approximately half of the lifetime dose the results on a variety of NbTi superconductors show moderate changes of the critical current density j/sub c/ (approx. 10%), the percentage change of j/sub c/ is always larger at high fields (8 T) than at 5 T. After a rapid initial change the resistivity ratios of the Cu-stabilizer are found to decrease only slowly with increasing neutron fluence.

An Analysis of Teacher Perceptions of Inhibitors to Effective Classroom Teaching in Secondary Schools
The primary purpose of this study was to examine the inhibitors affecting classroom teaching by surveying the perceptions of secondary teachers. This purpose was based on the growing crisis of "teacher burnout" which was thoroughly documented. Since it appears that burnout most often affects those teachers who work in conventional classrooms, characteristics of teaching effectiveness within these classrooms were the basis for inhibitor comparison. Seven characteristics were produced by a crosstabulation of studies on effective teaching spanning the last fifty years. The inhibitor choices presented with these seven characteristics were extracted from an extensive list produced by the literature and classified under six areas of origin. The characteristics and inhibitors ultimately selected were surveyed among teachers in a large Southwest metropolitan area.

Analysis of Uranium Urinalysis and in Vivo Measurement Results From Eleven Participating Uranium Mills
Uranium urinalysis and in vivo examination results obtained from workers at eleven uranium mills between 1978 and 1980 were evaluated. The main purpose was to determine the degree of the mills' compliance with bioassay monitoring recommendations given in the draft NRC Regulatory Guide 8.22 (USNRC 1978). The effect of anticipated changes in the draft regulatory guidance, as expressed to PNL in May 1982, was also studied. Statistical analyses of the data showed that the bioassay results did not reliably meet the limited performance criteria given in the draft regulatory guide. Furthermore, quality control measurements of uranium in urine indicated that detection limits at ..cap alpha.. = ..beta.. = 0.05 ranged from 13 ..mu..g/l to 29 ..mu..g/l, whereas the draft regulatory guidance suggests 5 ..mu..g/l as the detection limit. Recommendations for monitoring frequencies given in the draft guide were not followed consistently from mill to mill. The results of these statistical analyses indicate a need to include performance criteria for accuracy, precision, and confidence in revisions of the draft Regulatory Guide 8.22. Revised guidance should also emphasize the need for each mill to continually test the laboratory performing urinalyses by submitting quality control samples (i.e., blank and spiked urine samples as …

Annual research plan, 1983-84. [Organic compounds derived from fossil substances]
The National Institute for Petroleum and Energy Research (NIPER) resulted from efforts by the Department of Energy (DOE) to ensure the continuity of the unique energy research capabilities that had been developed at the Bartlesville Energy Technology Center (BETC) over the past 65 years. This was accomplished by a Cooperative Agreement between DOE and IIT Research Institute (IITRI). The agreement to operate NIPER for the five fiscal years 1984-88 became effective October 1, 1983. The NIPER Annual Research Plan for 1983-84 consists of eight projects in the Base Program and 13 projects in the Optional Program. A sampling of potential Work for Others projects is also presented. The Base Program consists of five EOR and three Fundamental Petroleum Chemistry projects. The Optional Program has three EOR projects, one Unconventional Gas Recovery project, five APT projects, and four Advanced Utilization Research projects.

Anomalous Surface Impedance in Reentrant Ferromagnetic Superconductors
For ErRh/sub 4/B/sub 4/, owing to the critical spin fluctuations just above T/sub s/ (> T/sub c2/), the critical temperature at which surface ferromagnetism appears, the reciprocal penetration depth, lambda/sup -1/, decreases smoothly as T decreases toward T/sub s/. For Er/sub 0/ /sub 5/Ho/sub 0/ /sub 5/Rh/sub 4/B/sub 4/, the decrease in lambda/sup -1/ for T > T/sub c2/ is very small, and lambda/sup -1/ decreases abruptly at T/sub c2/.

Antiproton source beam position system
The TeV I Beam Position Monitor (BPM) system is designed to provide a useful diagnostic tool during the commissioning and operational phases of the antiproton source. Simply stated the design goal is to provide single turn position information for intensities of > 1x10/sup 9/ particles, and multi-turn (clocked orbit) information for beam intensities of > 1x10/sup 7/ particles, both with sub-millimeter resolution. It is anticipated that the system will be used during commissioning for establishing the first turn through the Debuncher and Accumulator, for aligning injection orbits, for providing information necessary to correct closed orbits, and for measuring various machine parameters (e.g. tunes, dispersion, aperture, chromaticity). During normal antiproton operation the system will be used to monitor the beam position throughout the accumulation process.

Application of toroidal multipoles to facilitate tokamak reactor studies
A method of calculating the vacuum magnetic flux for plasma equilibrium over a range of aspect ratio A and major radius R is presented. Toroidal multipoles are used to fit the vacuum flux for a set of reference equilibria and the fitted moments are then used to parametrize the flux over the design space in A and R. An example is given in which the equilibrium flux for a D-shaped tokamak plasma is predicted and compared with the actual equilibrium code vacuum flux.

Applied Science Division annual report, Environmental Research Program FY 1983
The primary concern of the Environmental Research Program is the understanding of pollutant formation, transport, and transformation and the impacts of pollutants on the environment. These impacts include global, regional, and local effects on the atmosphere and hydrosphere, and on certain aspects of human health. This multidisciplinary research program includes fundamental and applied research in physics, chemistry, engineering, and biology, as well as research on the development of advanced methods of measurement and analysis. During FY 1983, research concentrated on atmospheric physics and chemistry, applied physics and laser spectroscopy, combustion theory and phenomena, environmental effects of oil shale processing, freshwater ecology and acid precipitation, trace element analysis for the investigation of present and historical environmental impacts, and a continuing survey of instrumentation for environmental monitoring.

The Aural Perception of Pitch-Class Set Relations: A Computer-Assisted Investigation
Allen Forte's theory of pitch-class set structure has provided useful tools for discovering structural relationships in atonal music. As valuable as set—theoretic procedures are for composers and analysts, the extent to which set relationships are perceptible by the listener largely remains to be investigated. This study addresses the need for aural-perceptual considerations in analysis, reviews related research in music perception, and poses questions concerning the aural perceptibility of set relationships. Specifically, it describes and presents the results of a computer-assisted experiment in testing the perceptibility of set-equivalency relationships.
