Dimensionality And Internal Composition Of The Twenty-Two Item Mental Health Inventory, John William Fox

Masters Theses

Chapter I

Introduction

Social scientists have long been concerned with the relationships between mental disorder and various sociocultural factors, such as, social economic status, ethnic background, sex, age, and marital status. Until quite recently, the majority of studies that have investigated these relationships have defined cases of mental disorder solely in terms of whether or not an individual was in psychiatric treatment (see Faris and Dunham, 1939; Rose and Stub, 1955; Hollingshead and Redlich, 1958).

The utilization of psychiatric treatment as the only criterion of mental disorder, however, has been criticized by a number of researchers. Felix and Bowers (1948), …

Operant And Classical Conditioning Of Single Units In Area 18a Of The Rat’S Cortex, Francis E. Butler

Masters Theses

The effect of the previous history of a single unit on its present firing pattern was studied using classical and operant conditioning. The units were in area 18a of the rat's cortex. It was found that there are polymodal units in that area. The firing pattern can be changed using classical conditioning. The rate of firing can be increased one standard deviation above the mean rate by reinforcing with brain stimulation. The rate can also be changed one standard deviation below the mean rate. This occurs when the trials come at a fixed time and when the trials come at …

Successive Discrimination Reversal Learning In The Rat Offspring As A Function Of Maternal Stress During Gestation, Miles A. Kowall

Masters Theses

This paper itself with the effect of prenatal stress on the learning ability of the offspring, parental emotionality on learning ability, and how these two factors interact. Female animals were categorized as either high or low emotional by measures in the open field and then further divided into shock or no-shock groups. This provided the stress condition. All females were stressed during pregnancy. Cross fostering and fostering techniques were used to provide more stringent control measures so as to be able to extrapolate prenatal influence from post natal artifacts. This resulted in a 2X2X3 analysis of variance matrix with error …

Characterization Of Streptozotocin Induced Small Colony Phenotypes In Bacteria, David M. Zimmer

Masters Theses

Streptozocin-induced small colony variants of E. coli were characterized and found to have a genetic basis. Both E. coli and S. typhimurium were susceptible to the mutation causing small colonies. Small colony cell lines exhibited a greatly increased generation time and were shown to be non-motile, electron microscopy revealing a complete loss of flagella. The small colony phenotype was revertible by streptozotocin and nitrosoguanidine. The locus responsible for small colony phenotype in one strain of E. coli was found to map within a 19 minute segment of the chromosome between HfrH and HfrC.

The Evaluation Of An Activated Sludge Process At Elevated Temperatures, Peter J. Dawson

Masters Theses

"The feasibility of utilizing the thermal energy from an electric power plant to operate an activated sludge process at elevated temperatures (above 40°C) was assessed.

The practicality of using this heat was determined from a heat transfer analysis and the operation of the activated sludge process was evaluated from laboratory studies of a batch process treating domestic and synthetic sewage.

The tank size for a thermophilic activated sludge chamber could be reduced by 40 to 50% as compared to ambient temperatures. For thermophilic processes a temperature of 55°C is recommended because the transition phase between mesophiles and thermophiles is around …

Marshall Properties Of Asphaltic Concrete Containing Glass-Rich Fractions, James Joseph Schneider

Masters Theses

"The use of crushed waste glass as an aggregate in asphaltic concrete has been suggested as a means for re-using glass separated from municipal refuse. Laboratory studies and field installations have generally utilized clean glass obtained by hand sorting bottles from the other refuse and crushing them to produce a desired gradation. For this type of asphalt to be economical though, the glass fraction must be separated mechanically. For mechanically separated materials, the glass-rich fraction also contains such items as metal, bone, rubber and other non-glass materials.

The objective of the study was to determine the effects upon Marshall properties …

An Investigation Into The Degree Of Correlation Between Air Flow Rates, Bacteria In The Air And Post-Operative Infections In Hospitals, Carl Eugene Intag

Masters Theses

"Post-operative infections are a recognized problem in the medical and hospital professions. Annual costs and deaths due to infections in the U.S.A. have been estimated at $8-$9 billion and 10,000 lives respectively. The air lS one potential path in transporting contaminants that may cause an infection. Yet, the degree of influence airborne contaminants have in causing infections is a topic of much debate. As a result of the need for more information in this area, this investigation was undertaken to determine the degree of correlation between post-operative infection rates, bacteria in the air, and air flow rates.

Heavy Metal Concentrations In The Waters Of The Springfield Area, Missouri, Anita Louise Williams

Masters Theses

"Water samples consisting of streams, springs, lakes, deep wells, and shallow wells were collected from various locations around the Springfield area. These were analysed for concentrations of the heavy metals of lead, copper, cadmium, zinc, mercury, and iron. Heavy metal contents in the waters occasionally show local concentrations. The zinc content can be related to known minor mineralized areas around Springfield. Some iron content in the surface waters and shallow aquifers is contributed by the iron-bearing clays and pyrites in the shallow formations.

The ranges of heavy metal values in the Springfield area are in ppb: lead, 1 to 70; …

Treatment Of A Pharmaceutical Waste With The Anaerobic Filter, Norman Dale Dennis Jr.

Masters Theses

"The anaerobic filter is essentially a plug-flow, packed-bed, column type reactor in which the anaerobic bacteria responsible for the waste stabilization are attached to the filter media. This process is a relatively new concept in waste treatment which has been used only in laboratory studies. The objective of this study was to evaluate anaerobic filter performance when used to treat an actual industrial waste under controlled conditions of flow rate, organic strength and temperature.

Four 0.5 cu ft (14.25 l) laboratory filters were operated for 180 days at 35° C using a pharmaceutical waste as the substrate. By varying influent …

Disposal Of Cattle Feedlot Wastes By Anaerobic Digestion, Eric Bayard Rapp

Masters Theses

"Disposal of animal waste represents a severe environmental problem, particularly in areas such as cattle feedlots where livestock are concentrated. Animal waste can be converted to carbon dioxide and methane by the autocatalytic process of anaerobic fermentation. A scheme, based upon this process, for the disposal of the waste from two different size feedlots is presented. The design of this process is based on kinetic data from the literature which are fitted to a kinetic model including diffusional resistances. Economic calculations based upon available cost data are made to determine the profitability of the process. Economic evaluations indicate that this …

A Study Of The Splash-Plate Tower Concept, A Biological Wastewater Treatment Process, Robert Joseph Millman

Masters Theses

"Different modifications and newer methods of treatment which utilize the basic trickling filter concepts, such as the Bio-Disc process, have been developed to increase the efficiency of wastewater treatment. The purpose of this investigation was to develop and evaluate a newer such method called the splash plate concept.

The splash-plate concept utilizes a series of circular plates mounted horizontally on a vertical axis. This allows the wastewater being treated to travel over one plate to the edge and splash down to the next lower plate and so on throughout the tower. A total of four units were operated at different …

Transmission Measurements Through Liquids In A White Cell, David Earl Hurley

Masters Theses

"The suitability of using the White cell for determining the extinction coefficient of liquids was examined by measuring the attenuation of electromagnetic radiation, in the visible part of the spectrum, through distilled water. The analysis of the transmittance measurements through liquids in a White cell does not provide a sufficient number of independent equations to solve directly for the extinction coefficient. Reasonable estimates however can be made by employing a correction which accounts for changes in the mirror reflectance due to a liquid-mirror interface.

The reduction in the transmittance of distilled water due to an oil film was studied for …
