A Mathematical Model For The Neutron Dependence Of Neutral Base Region Recombination, Jonas Bereisa Jr.
A Mathematical Model For The Neutron Dependence Of Neutral Base Region Recombination, Jonas Bereisa Jr.
Masters Theses
"A discrete, deterministic, mathematical model is developed for the neutral bulk base region of graded base devices which accounts for both the effects of recombination and the built-in electric field in the bulk base region at low, intermediate, and moderate current/injection levels. This model is applied to a study of neutron radiation effects in double diffused silicon transistors. Exact expressions are developed for the injected emitter, base and collector currents, the base recombination term, and the ratio of base current increase to collector current decrease as functions of device geometry, impurity profile, and neutron fluence. Neutron-induced current gain degradation is …
Comparison Of The Buckley-Leverett Technique With A Numerical Simulation Model Containing Heterogeneity And Capillary Pressure, Krishna Kumar Singh
Comparison Of The Buckley-Leverett Technique With A Numerical Simulation Model Containing Heterogeneity And Capillary Pressure, Krishna Kumar Singh
Masters Theses
"A numerical model for a linear, two-phase fluid flow system has been developed with the capabilities of accounting for heterogeneity and capillarity. The model developed is general enough to analyze either water-oil or gas-oil systems. A hypothetical petroleum reservoir (containing only water and oil) under water flood was studied. The results for the homogeneous, no capillary pressure case were found to be similar to those obtained by the Buckley-Leverett technique. The study shows that the Buckley-Leverett is accurate even for a certain degree of heterogeneity. Also, capillarity does not substantially alter the results for the system studied. The results obtained …
The Assignment Problem And A Suboptimal Solution Technique, William Barry Gregory
The Assignment Problem And A Suboptimal Solution Technique, William Barry Gregory
Masters Theses
"A technique is presented which finds a fast suboptimal solution to the assignment problem. This same technique is then applied to two large dynamic programming problems for which the optimal solution is not known. These examples illustrate how easily this technique can be applied and that it is better than most optimizing techniques because it is fast, cheap and only minor hand calculations are needed. The effect of different initial solutions and their value are compared and it is found that the initial solution is not as significant in a suboptimal technique as in an optimizing technique. The initial solution …
The Smelting Of Lead Drosses, Humberto Adolfo Arzabe
The Smelting Of Lead Drosses, Humberto Adolfo Arzabe
Masters Theses
"The constitution of the matte and bullion obtained by the smelting of lead drosses coming from the cooling of lead blast furnace bullion was investigated by metallographic, chemical, electron-microprobe, and X-ray means. At smelting temperatures (1200°C to 1300°C) two liquid phases are in equilibrium. A liquid lead phase with low concentrations of copper and sulfur, and a lighter liquid matte phase containing a high concentration of copper and sulfur with some dissolved lead. On cooling to room temperature the matte precipitates cuprous sulfide, a eutectic mixture of cuprous sulfide and lead sulfide with a deficiency of sulfur, and metallic lead …
St. Louis Limestone, Stratigraphy And Petrography, Near Its Type Locality, Abd El-Aziz El-Hady A. Borahay
St. Louis Limestone, Stratigraphy And Petrography, Near Its Type Locality, Abd El-Aziz El-Hady A. Borahay
Masters Theses
"The St. Louis Limestone of the Upper Meramecian Series, Mississippian System, is typically lithographic, light-to light-olive gray in color, dense, and fractures conchoidally. It is brecciated, especially in the lower part, and contains some chert nodules. Oolites are present close to the top of the formation. The Salem-St. Louis contact is placed at the base of the lowest breccia zone and the top of Salem is characterized by crystalline quartz and abundance of chert nodules. The appearance of typical Ste. Genevieve oolites with sand-size quartz grains indicates the St. Louis-Ste. Genevieve contact. The St. Louis Limestone is characterized by dominance …
The Closed Cycle-External Combustion Engine And Air Pollution, Galen Lee Pearson
The Closed Cycle-External Combustion Engine And Air Pollution, Galen Lee Pearson
Masters Theses
"The impact of the internal combustion engine on the air pollution problem in this country was presented and alternative propulsion systems for the land transportation vehicle were investigated. The potential characteristics of the more promising closed cycle-external combustion engine concepts were established and discussed. The closed thermodynamic power cycles analyzed include the Rankine, Stirling, and Feher supercritical cycles. Thermodynamic property data on eighteen candidate working fluids for the Rankine and Feher supercritical power cycles have been assembled and were presented in a utilizable form. The thermal efficiency (ratio of the net work out to the heat input) and the many …
Metabolism Of 3-Iodotyrosine And 3,5-Diiodotyrosine By Thyroid Extracts, Shih-Ying Sun
Metabolism Of 3-Iodotyrosine And 3,5-Diiodotyrosine By Thyroid Extracts, Shih-Ying Sun
Masters Theses
"A porcine thyroid enzyme was extracted from thyroid tissue by homogenization and differential centrifugation. The enzyme was capable of metabolizing both 3-iodotyrosine and 3,5-diiodotyrosine. All of the thyroid subcellular particles produced a fluorescent compound when incubated with these substrates. When the 1,000 x g sediment was supplemented with the 48,000 x g supernatant a second compound was formed. The compound was UV absorbing and has been identified as either 3-iodo-4-hydroxybenzaldehyde or 3,5-diiodo-4-hydroxybenzaldehyde depending upon which substrate was used. The 1,000 x g sediment was solubilized with 1% Conoco 1012-6 detergent. The activating factor in the 48,000 x g supernatant was …

Investigations Of Several Variables In The Dwight-Lloyd Mcwane Ironmaking Process, James Orlan Hood Jr.
Investigations Of Several Variables In The Dwight-Lloyd Mcwane Ironmaking Process, James Orlan Hood Jr.
Masters Theses
"The Dwight- Lloyd McWane Ironmaking Process (D-LM) is the first commercial process of its particular type and one of the few commercial processes involving prereduction of iron ore in existence today. This presentation reviews some promising ironmaking processes which involve iron ore prereduction, with special attention being given the D-LM process. Although the D-LM process is continuous from iron ore to high quality molten cast iron, the research and discussion herein is limited to principal variables involved in the production of high quality carbonized pellets in the prereduction phase of the operation. The variables of process temperature and pellet carbon …
Digital Simulation Of A Costas Loop Demodulator In Gaussian Noise And Cw Interference, Ajay Mugatlal Mehta
Digital Simulation Of A Costas Loop Demodulator In Gaussian Noise And Cw Interference, Ajay Mugatlal Mehta
Masters Theses
"A digital computer model of a Costas loop has been employed to study the effects of Gaussian noise and continuous-wave interference on the detection of biphase modulated signals. The dependence of bit-error probability, mean-square error between input and output, phase-error variance and threshold on signal-to-Gaussian-noise power ratio, interference-to-Gaussian-noise power ratio and frequency offset of the interference have been investigated and compared with previously obtained experimental results. The model has been verified for its accuracy in the case of no noise and when Gaussian noise is present at its input"--Abstract, Page ii.

Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley
Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley
Masters Theses
The short-term growth response of etiolated pea stem segments (Pisum sativum L., var. Alaska) was investigated using a high-resolution growth recording device. The immediate effect of treatment with indoleacetic acid (IAA) is an inhibition of growth. This inhibition lasts about 10 minutes and then the rate of elongation rises abruptly to a new steady rate about 4 times the rate of elongation before auxin treatment. This rapid steady rate of elongation, however, continues for only about 22 minutes before declining suddenly to a lower steady rate of growth about 2 times the rate of elongation before the addition of auxin. …
