Characterization And Staged Lagoon Treatment Of Swine Feedlot Waste, Abraham H. Loudermilk Jr.

Masters Theses

"Feedlot pollution is developing into a serious problem because of the trend toward intensive farming techniques and the increasing number of animals in confinement feeding operations. The purpose of this study was to characterize swine waste collected under a slotted feeding floor using a water-carriage system, and to evaluate the treatment of this waste in a staged lagoon system consisting of an anaerobic, a dual anaerobic-aerobic, and an aerobic lagoon. A small feeding floor unit capable of maintaining 3 separate groups of animals, and a pilot 3-lagoon system were designed, constructed, and operated for a period of approximately 4 months. …

Thermal Stresses And Movements In Bridges, Joseph Charles Reynolds

Masters Theses

"A state of the art regarding the thermal behavior of bridges and considerations to be given to the resultant thermal effects is presented. The results of studies related to the thermal effects on bridges are reviewed. Studies attempting to relate environmental factors to bridge temperatures, and subsequently to bridge movements and stresses, indicate that the task is extremely complex. Some correlation has been made between equations predicting bridge temperatures and movements based on weather bureau records. However, further research is needed to evaluate the effects of factors other than temperature, such as creep, shrinkage, and humidity on bridge movements and …

The Electric Field Strength Dependence Of Neutron-Induced Defects In Silicon P-N Junctions, Paul Edward Johnson

Masters Theses

"The effect of high electric field strengths (10⁴ to 10⁵ V/cm) present during neutron radiation on the neutron-induced defects is determined by utilizing the high electric field strength inherent in the emitter-base transistion region of an n-p-n transistor. A method is presented for the separation of neutron and gamma effects. Previous theoretical work on the ratio of base current increase to collector current decrease is applied to experimental data. The variations of the space-charge region volume damage introduction rate with neutron fluence and the average electric field strength are determined experimentally in order to obtain a measure of this effect. …

Use Of Glass Separated From Municipal Refuse In Asphaltic Concrete, Thomas Eugene Keith

Masters Theses

"The recent interest in municipal refuse recycling has brought about the development of several systems for separation of the refuse into components. One of the components reclaimed is a glass-rich fraction which, although primarily glass, contains various non-glass materials which the system is not able to remove. Clean waste glass can be used as an asphaltic concrete aggregate, and it would be desirable to use this glass-rich fraction in a similar manner. However, the effect, if any, of the non-glass components on the properties of an asphaltic mixture must be determined in order to utilize the glass-rich fraction with a …

An Investigation Of Stage I Fatigue Crack Growth In Fcc, Bcc, And Hcp Metals, Marion Anthony Russo

Masters Theses

"The objectives of this investigation were to 1) determine if Stage I mode or fatigue crack growth could be extended beyond the 45 degree maximum shear plane in metals having a face-centered, body-centered and hexagonal close pack crystal structure; 2) identify the crystallographic planes or crack propagation in Stage I growth in each crystal structure; 3) characterize the fracture surface topography or Stage I growth in each crystal structure. The test material used for this investigation consisted of alpha brass (70% Cu, 30% Zn), Armco iron and commercially pure titanium which are representative of FCC, BCC, and HCP crystal structures …

Managerial Appraisals - A Systems View, James Thomas Hatlan

Masters Theses

"In the past decade much has been written concerning the performance appraisal which can be defined as the systematic analysis of the individual with respect to his performance on the job. The appraisal's importance lies in the fact that its impact is felt in the areas of control, promotion, and managerial development all of which are essential for the progressive firm. This study is an attempt to offer something new and something different. The author offers a systematic study of industry in general with specific help from key corporations and utilities. His investigations encompass the three elements of appraising and …

Preliminary Studies With A Variable Transfer Composite Polymer Membrane., Samuel Walter Dortch

Masters Theses

"A preliminary study was done to determine the feasibility of using a compressed fibrous teflon (PTFE) silicone polymer membrane in extracorporeal oxygenation devices. A series of composite membranes were fabricated, using different concentrations of a dimethyl silicone polymer dissolved in petroleum ether, to give membranes having variable oxygen transfer properties. A gas-gas system was chosen to obtain the necessary transfer data. Data were obtained by transferring pure oxygen through the membranes into a mixture of 47 mole percent oxygen and 53 mole percent carbon dioxide. All analyses were obtained by chromatographic techniques. The results of these experiments show that membranes …

An Experimental Study Of Power Systems, Nguyen Quang Duoc

Masters Theses

"For three phase AC power systems consisting of synchronous machines interconnected by transmission lines and other electrical transmission equipment, the power transmitted and the stability of the system depend upon the constants of synchronous machine and the characteristics of the transmission lines. The purpose of this work is to design and set up a model of a power system in the laboratory, measure the constants of synchronous machines, the power angles and power flows of the system. An investigation of the effects of the saturated machines is based upon the laboratory data.

This work is intended primarily as a tool …

The Development And Empirical Validation Of A Teaching Program, Arlene Chmil

Masters Theses

The original purpose of this study was to teach college students to write psychology laboratory reports. A programmed text on how to draw a graph that would meet the publication requirements as specified by the American Psychological Association was written and tested on a small sample of psychology stidents. Results showed that the rules were not adequate discriminative stimuli for controlling behavior. It was necessary to give the students discrimination training with examples related to those rules. There was a high percent of errors on rules that pertained to the concepts of the independent and dependent variables, and the task …

The Influence Of Visual Perception On The Academic Performance Of The Mentally Retarded, Shirley A. Knapp

Masters Theses

Visual perception refers to the process of receiving and analyzing sensory information through the medium of the eye. The report extensively surveys literature concerning the developmental processes and characteristics of visual perception. The research tended to show a relationship between visual perceptual maturity and academic achievement. The prominent remedial programs were discussed in conjunction with supporting or disputing research concerning the alleged benefits. Finally, studies dealing with the visual perception of the mentally retarded were proffered.

A research project was conducted with mentally retarded and non-retarded subjects, matched according to mental age. The Frostig Developmental Test of Visual Perception was …
