Optumr A Digital Computer Program To Cost Optimize A District Heat Piping Network To Remove Waste Heat From Nuclear Power Reactors, James Richard Hendricks
Masters Theses
"The thermal pollution problem of a nuclear reactor electrical generating facility can be eliminated if an economical, productive use for the waste heat can be found. The computer program presented here is designed to investigate the economic feasibility of utilizing this waste heat to heat buildings. The program optimizes a district heating network using the reactor's rejected heat and performs a comparative analysis with a selected conventional heat rejection system. The results indicate that the system is feasible only if the reactor can be sited relatively close (5 miles) to an urban center. Increasing national concern regarding thermal pollution and …
Efficiency And Loss Mechanism Of The Electro-Fluid Dynamic Momentum Transfer Process Applied To Propulsion Systems Using Atmospheric Air As The Working Fluid, Roger Coy Crites
Efficiency And Loss Mechanism Of The Electro-Fluid Dynamic Momentum Transfer Process Applied To Propulsion Systems Using Atmospheric Air As The Working Fluid, Roger Coy Crites
Masters Theses
"The general equations governing EFD (electrofluid dynamic) flow are established, simplified, and solved in closed form to provide a mathematical model of an ideal EFD propulsion system. This mathematical model, in conjunction with an analysis of ion-neutral and neutral-neutral molecular collision phenomena, indicates that the cause of inefficiency in the EFD propulsion system is the system entropy increase associated with the diffusion of ion momentum through the neutral fluid. This loss mechanism is shown to be analogous to resistive heating losses in a constant voltage linear electrical network and can be minimized by obtaining minimum ion mobility. It is shown …
Investigation Of The System Al₂O₃-Teo₂-O₂, Vera Zelenkova Sestak
Investigation Of The System Al₂O₃-Teo₂-O₂, Vera Zelenkova Sestak
Masters Theses
"The system Al₂O₃-TeO₂-O₂ has been investigated by X-ray diffraction and differential thermal analysis in air and in sealed silica ampoules. The tellurate, Al₂TeO₆, with tellurium in the +6 valence state, forms in air but not in vacuum at 1 mm pressure. A second phase, a tellurite, possibly Al₂Te₂O₇, forms in air or vacuum by devitrification. The glass-forming region is wider than previously stated and is more extensive in vacuum--from 50% to 98% TeO₂. Tentative phase boundaries have been placed for the system in air and vacuum"--Abstract, page ii.

Special emphasis is directed toward the explanation of laboratory techniques developed for this study to measure the oxygen uptake rate. The effects on oxygen consumption of temperature, nature of sludge, initial oxygen tension, and sludge consolidation are discussed. Benthal sludge samples were taken from three locations in the pond. Oxygen consumption studies were conducted in a specially designed plastic cylinder which included a novel magnetic mixing system. …
The Anodic Oxidation Of Oxalic Acid On Au, Steven C. Mueller
The Anodic Oxidation Of Oxalic Acid On Au, Steven C. Mueller
Masters Theses
"The anodic oxidation of oxalic acid on Au has been studied at 80°C in aqueous media. The reaction rate was measured as a function of potential, oxalic acid concentration, pH, and temperature in H₂SO₄-K₂SO₄-KOH solutions of unit ionic strength. The oxalic acid was oxidized only in acidic media. The oxidation to CO₂ was essentially complete. A first order dependence of the rate on both pH and undissociated oxalic acid was found. A mechanism is proposed in which the first decarboxylation is the rate determining step"--Abstract, page 1.
An Explicit Simulation Of Overland Flow, Glendon Taylor Stevens
An Explicit Simulation Of Overland Flow, Glendon Taylor Stevens
Masters Theses
"Computer simulation of overland flow requires a mathematical model which converges to a true solution. This paper presents a method, based on measurable physical parameters, which insures convergence of a fixed grid explicit numerical solution. Analysis of a wide range of overland flow plane parameters has resulted in an equation of the form Δt = 0. 2 ΔX/So, for the time step increment. This equation provides values for Δt that will insure stability and convergence of the fixed grid explicit numerical method of solving the spatially varied unsteady flow equations. The effect of subarea shape on the rising …

Evaluation Of City And Region Planning Techniques, Charles Clay Miller
Masters Theses
"The transportation and community planning effort in the United States has resulted in the expenditure of a great deal of time and money. However, the result of this effort has largely been unusable because of a lack of an effective formalized planning method. this thesis presents summarizations of the planning methods employed in ten plans which are typical of the U.S. Planning Effort. Each of these methods are critiqued in the light of a proposed planning method. The Federal Government has recently required the adoption of a Planning, Programming and Budgeting System (PPBS) in an effort to formalize a scientific …
Analysis And Control Of Noise Produced By Small Pneumatic Tools, Phillip Ray Elam
Analysis And Control Of Noise Produced By Small Pneumatic Tools, Phillip Ray Elam
Masters Theses
"Noise measurements were made near the exhaust of three small pneumatic tools operating under various loads and with various components removed. One-third octave analyses were performed on the noise for identification of noise sources and to determine possible noise reduction techniques. It was determined that the noise spectra consisted of broad band turbulent flow noise plus periodic components at the tool motor blade passage frequency and harmonics of this frequency. One tool, the nut setter, was selected for reverberant field noise analyses and noise reduction studies. Reverberant field measurements indicated that most of the tool noise was transmitted through the …

Penetration In A Graded Filter, William Chuan Shen
Penetration In A Graded Filter, William Chuan Shen
Masters Theses
"An experimental laboratory study conducted to examine clogging within and penetration of fines into a single layer graded filter. Hydraulic gradient, filter gradation and flow direction were varied. Forty one tests gave over six hundred individual penetration depths. The magnitude of penetration in filters with considerable variation in gradation patterns correlated with an average hydraulic radius based on the volume of voids and an approximated total surface area. It has been shown than an increased thickness of poorly graded filter will stop penetration such as that caused by seepage erosion. A relationship between hydraulic radius, penetration depth and probability of …
Shear Strength Characteristics Of Crushed Glass, Fred Ray Browning
Shear Strength Characteristics Of Crushed Glass, Fred Ray Browning
Masters Theses
"Drained and undrained triaxial compression tests were performed on two gradations of crushed glass in order to determine the compressibility and shear strength characteristics. Consolidation pressures varied from 10 to 100 psi. Volume changes during consolidation were discussed because of the dependency of shear strength behavior on the density condition at the end of consolidation. Stress-strain-volume change characteristics were observed in order to discuss the load-deformation and dilatancy relationships and the effects of varying density, gradation and consolidation pressure. Stress-strain properties were also determined for the undrained tests. The undrained tests were constant volume tests, thus having no dilatancy effects. …
The Semibullvalene Question: A Semi-Empirical Molecular Orbital And Bond Energy Approach, Shiow Yeh Lee
The Semibullvalene Question: A Semi-Empirical Molecular Orbital And Bond Energy Approach, Shiow Yeh Lee
Masters Theses
"Semi-empirical molecular orbital calculations of the Extended Ruckel and MIND0/1 type have been performed on semibullvalene and the supposed transition state for its degenerate [3,3] sigmatropic rearrangement. The results have been coupled with bond energy calculations to ascertain whether semibullvalene is homo-aromatic or is undergoing a rearrangement of exceedingly low activation energy. A preponderance of the resulting data suggests that semibullvalene is homo-aromatic"--Abstract, page ii.
A Study On The Feasibility Of Using Pipelines For The Collection And Transportation Of Urban Solid Wastes, William Leo Sago Jr.
A Study On The Feasibility Of Using Pipelines For The Collection And Transportation Of Urban Solid Wastes, William Leo Sago Jr.
Masters Theses

Masters Theses
"The clay mineralogy and Standard Proctor compaction characteristics of clayey residual soils developed on the Salem Plateau of the Ozark Physiographic Province and used in earth dam construction were studied. A review of the geology of the Salem Plateau is presented along with a discussion of the factors controlling the development of soils on carbonate bedrock in a high leaching environment. The predominant soil clay mineral was found to be a poorly crystallized kaolinite rather than halloysite as has been postulated by others. Minor amounts of triple-layer minerals and an undetermined amount of an alumino-silicate gel are indicated. The effects …
Evaluation Of The Carbon Adsorption Method With Parallel Solvent Extraction Studies, Stanley Kent Wagher
Evaluation Of The Carbon Adsorption Method With Parallel Solvent Extraction Studies, Stanley Kent Wagher
Masters Theses
"In spite of the importance of the carbon adsorption method (CAM) in determining drinking water quality and its wide use in research and plant control studies, little work has been undertaken to quantitatively and qualitatively evaluate the method, especially under field conditions. This investigation was, therefore, undertaken in order to develop a test system consisting of equipment and procedures which would make possible the field evaluation of the carbon adsorption method by parallel solvent extraction studies, and to employ this system in preliminary field investigations to establish guidelines for the experimental conditions required for its effective application. The test system …
The Anodic Dissolution Of Tin In Acidic Chloride Solutions, Edward Chung-Hong Liu
The Anodic Dissolution Of Tin In Acidic Chloride Solutions, Edward Chung-Hong Liu
Masters Theses
"The anodic dissolution of Sn in acidic chloride solutions (pH = -2.0 to 2.9) was studied at 25ºC. The apparent valence of the dissolving ions varied from about 0.4 to 2.4, a function of both electrolyte and c.d. The complexing of Sn⁺² by Cl⁻ had an important influence with SnCl₃⁻ apparently being the dominant products. A reaction sequence is proposed involving the step-wide oxidation of Sn accompanied by reaction with Cl⁻"--Abstract, page 1.
