Slip Dislocation Formation During Continuous Wave Laser Annealing Of Silicon, Helmut Baumgart Jan 1981

Slip Dislocation Formation During Continuous Wave Laser Annealing Of Silicon, Helmut Baumgart

Electrical & Computer Engineering Faculty Publications

High-voltage electron microscopy (HVEM) has been used for the investigation of the defect structure in cw laser-annealed silicon. We report for the first time a (HVEM) analysis of the formation processes involved in the nucleation and glide of slip dislocations during epitaxial regrowth by cw laser annealing of ion-implantation damaged silicon layers. Based on the combined optical and HVEM observations a model of the dislocation generation and glide processes is presented.


Model For Coal-Fired Reactors, Philip J. Smith, Thomas H. Fletcher, L. Douglas Smoot Jan 1981

Model For Coal-Fired Reactors, Philip J. Smith, Thomas H. Fletcher, L. Douglas Smoot

Faculty Publications

An axisymmetric, elliptic model has been developed for analysis of confined, turbulent coal-laden diffusion flames. The scheme is Eulerian for gases and Lagrangian for particles. The approach emphasizes the turbulent fluid mechanics of the mixing-limited gas phase reaction processes. The two-equation (k-─ e) turbulence model is used for closure. Particle drag and turbulent particle diffusion are also modeled. Gaseous combustion is modeled with a probability density function for the mixture fraction. Fluctuations in mixing of inlet streams and coal off-gas are considered. Coal pyrolysis and oxidation reaction processes are assumed to be slow with respect to the turbulent time scale. …


Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan Jan 1981

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan

Reports

The economic well-being of the semiarid intermountain area requires efficent use of available water supplies. Agriculture, the major water-consuming industry, depends on irrigation water. The adoption of sprinkler systems that increase on-farm irrigation "efficiencies" and the area which can be irrigated from upstream diversions may interfere with the "tenure" of downstream water rights. These downstream effects need to be evaluated before allowing farmers to use the water "saved" to irrigate additional acreages or crops to obtain greater profits. The problem in letting farms expand their irrigated acreage is that the individual farmer increases his profits through increased consumptive use. The …


A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer Jan 1981

A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer

Reports

Introduction: Scrubber wastes obtained in an affort to limit air pollution generated by coal-fired pwoer plants may contribute to another possible sources of pollution. To date, scrubber wastse have been in a liquid phase which causes disposal problems partially due to the liquid characteristics. The use of solid scrubber wastes and the land deposition of such wastes is proposed. The feasibility of solid scrubber wastes disposal in landfills is under question. The primary area of concern is the effect that water percolation through such wastes would have on groundwater quality parameters. Contamination could result either as precipitation travels downward through …

Physical Principles Of Local Heat Therapy For Cancer, Charles F. Babbs, David P. Dewitt Jan 1981

Physical Principles Of Local Heat Therapy For Cancer, Charles F. Babbs, David P. Dewitt

Weldon School of Biomedical Engineering Faculty Publications

Local hyperthermia therapy for cancer can produce selective heating of solid tumors on the basis of known physical laws. If energy is deposited in the general region of the tumor, temperature tends to develop in the tumor higher than that in surrounding normal tissues. The goal of therapy is to achieve cytotoxic temperature elevations in the tumor for an adequate period of time, without damaging nearby normal tissues. Several modalities exist for local heat treatment, of which radiofrequency and ultrasound offer the most promise for controlled, localized heating at depth. A paucity of blood flow in the tumor compared to …
