A Comparison Of Incarcerated And Non-Incarcerated Women Based On The M.M.P.I., Rose Marie Carter

Masters Theses

The field for research on women offenders provides an extensive opportunity for scientific investigation. Many writers (Gibbons, 1971; Cunningham, 1964; Sutherland, 1968) have discussed the causes of crime and their resulting social implications. Organized mass presentations of the movement of crime among women is negligible. Today female incarcerates make up approximately 11 per cent (Lerner, 1972) of the total number in state and federal penitentiaries. Previous research (Cunningham, 1964) on female felons found poor self-concept, excessive dependency and pathological emotionality to be a consistent pattern in women criminals. Other research (Apfeldorf, 1971; Guze, 1959) found criminal and non-criminal groups could …

Effect Of Spatial Titration On Task Performance, Lawrence M. Glowacki

Masters Theses

A spatial titration method was used with a reinforcement schedule to determine task-reinforcement area separation most preferred and effective in producing high task performance. Two third-grade boys were given task contingent reinforcement where the task was solving arithmetic problems. Following shaping to stable response rates, the titration operation was introduced. Errors decreased the task-reinforcement area distance while correct responses increased the distance. With the introduction of Titration Phase 1, both subjects' incorrect responses produced a zero task-reinforcement area separation. In Titration Phase 2, both subjects were started at the opposite extreme of the reinforcement continuum. Repeated errors produced a zero …

The Effect Of Porosity On Strength Degradation In Thermally Shocked Alumina, Russell David Smith

Masters Theses

"Strength degradation and crack propagation in Al₂O₃ are shown to depend on the initial strength and porosity of the material. Specimens were fabricated containing between 0 and 5% induced cylindrical, two dimensional, and spherical porosity. The strengths of the various porosity samples decreased discontinuously at a critical quenching temperature. No difference was observed in the critical temperature for the various aluminas; initial strength decrease occurred between 165°C and 175°C temperature differential. The strength retained after thermal shock decreased with increasing initial strength. The degree of damage sustained upon shocking was also characterized by crack density and crack …

Quantitative Overdesign By Stochastic Simulation, Raymond A. Freeman

Masters Theses

"The determination of overdesign, or safety, factors for industrial processes is an art acquired by the engineer through experience. In general, safety factors are increased as the uncertainty of the process variable increases; a procedure that can be expensive if safety factors are specified too small or too large. A single release of harmful substances from pollution control installations may cause irreparable damage. Likewise, the production of an off specification product by a chemical process costs money and resources. These facilities must often be designed for widely fluctuating flow rates, compositions, temperatures, and etc. Consequently, the selection of the proper …

Nutation Control During Precession Of A Spin-Stabilized Spacecraft, Richard James Donner

Masters Theses

"The effects of precession thrust pulses and energy dissipation upon nutation of a spin-stabilized spacecraft are studied. Methods for controlling nutation during a precession maneuver are proposed and examined. In particular, a precession modulation control law is developed which uses precession thrust pulses to control nutation. Digital simulations show that precession control with separate nutation control is the fastest precessing system; however, the precession modulation method is only fractionally slower while not requiring a separate nutation control system"--Abstract, page ii.

Driver-Vehicle-Roadway Interaction Model, Mark E. Jaeger

Masters Theses

"A non-trivial simulation model has been developed which combines driver and vehicle dynamics with the roadway into one system. The model was successfully simulated on a portion of an existing roadway with the dynamic response and performance of the simulator being subjectively realistic. By implementing the idea of the interaction of variables, a much more detailed and representative response is obtained as compared to previous models based solely upon a single-factor-effect approach. By analyzing a simulated vehicle's velocity and trajectory, it is felt that an increase in driver "look ahead" distance or a decrease in vehicle velocity tends to improve …

Liquid-Liquid Extraction With First Order Reaction : A Mathematical Simulation, Alan Wayne Smith

Masters Theses

"Models for mass transfer to droplets based on film theory with first order chemical reaction are proposed and compared with experimental data. The experimental extraction data is available from the work by Andoe (1968). The physical system used was benzene as a continuous phase and water as a dispersed phase with 2-chloro-2- methyl propane the solute diffusing into and reacting in the droplet. This system had a high interfacial tension (31.0 dynes/cm) and droplet Reynolds numbers ranging from 600 to 1345.

The predicted results of this work are in the form of the dimensionless total mass transferred to the droplet …

Model Correction For The Formation Of Amorphous Silicon By Ion Implantation, John Robert Dennis

Masters Theses

"ESR has been used to study the formation of an amorphous layer in silicon by ion implantation. The room temperature implants were done at 20 keV with low dose rates. The critical dose was determined as a function of ion mass for six different ion species. Our experimental heavy ion results agree with those found by other ESR investigators at higher energy, but are not the same for light ions. However, our light and heavy ion results agree with electron microscope measurements for low energy implants. An energy-independent model for the formation of amorphous silicon by ion implantation has …

Approximate Normal Mode Method To Determine The Response Of Certain Nondiagonalizabel Vibratory Systems, Jayaram Seshadri

Masters Theses

"An approximate normal mode method is developed which permits certain normally nondiagonalizable, nonconservative systems to be solved by superposition of uncoupled coordinates.

An approximate solution for a nonproportionally damped, multi-degree of freedom system is obtained by using a perturbation technique. The system is then reduced to a proportionally damped system by means of a modification to the damping factor so that the effect of the off-diagonal terms of the modal damping matrix is included. This modification produces a damping matrix that can be diagonalized by the normal mode technique. An approximate criterion is used for the determination of the modified …

A Comparison Of Three Urban Hydrology Models, Richard F. Astrack

Masters Theses

"Three models, the British Road Research Laboratory Hydrograph Method, the Hydrocomp Simulation Program, and the HEC-1 Flood Hydrograph Package, are applied to the Boneyard Creek basin. Comparing the ability of these models to reproduce the observed peak discharge, time of the peak, and the first runoff volume determines the accuracy of these models"--Abstract, page iii.

On The Complex Index Of Refraction Of Bulk Materials, Carol Jeanne Warren

Masters Theses

"As a part of the investigation of classical reflectance, it is determined that the hemispherical reflectance for a material with a particular pair of optical constants can be approximated by computing the angular reflectance at sixty degrees, using Fresnel's generalized reflectance formulas.

Reflection methods for the purpose of determining the optical constants of a variety of materials are discussed. The unpolarized reflectance versus angle of incidence technique is used for determination of the optical constants of bulk solids. Restrictions on the simultaneous solution of the Fresnel equations are determined and a computer program is developed to compute values necessary to …

Adsorption Of Water On Gold, Jean-Marc Louis Deschanel

Masters Theses

"Water adsorption isotherms on gold films were measured with a quartz crystal microbalance. Two gold films were studied: a "dirty" gold film contaminated by approximately one monolayer of carbon, and a "clean" gold film prepared by evaporating gold from a heated tungsten wire under high vacuum.

Water was found to chemisorb on both films according to a Freundlich type adsorption isotherm. Isosteric heats of adsorption were computed from the isotherm data. On the "clean" gold surface the isosteric heat showed a logarithmic decrease with increasing water coverage. The highest measured value for the heat of adsorption was 35 kcal mole …

A Study Of The Ability Of Surface Active Materials To Increase The Evaporation Rates Of Small, Freely Falling Water Drops, David Alan Sierawski

Masters Theses

"The evaporation rate at 30°C of water droplets partially covered by surface active materials (SAM) were determined. While two of the SAM were studied at a single dew point depression (ΔT_DP), seven others were examined over a range of ΔT_DP values. It was found, by comparison with pure water drops under identical conditions, that SAM increases the evaporation rate as compared to the rate of an uncontaminated drop. The lack of effect of the hydrophobic chain length and the possible effect of the hydrophilic group on this phenomenon are discussed. The explanation proposed is that at 30°C …

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 …

Corals Of The St. Louis Limestone In The Area Of Calhoun County, Illinois And St. Louis County, Missouri, William Earl Collins

Masters Theses

"The St. Louis Limestone and its equivalent formations crop out from Alaska south to Sonora and from Arizona east to Virginia. The St. Louis, in most cases, is fossiliferous and contains numerous species of foraminifers, echinoderms, bryozoans, molluscans, brachipods, arthropods and coelenterates. Algal mounds and mats are common. The rugose coral fauna of the Middle Mississippian (Meramecian) St. Louis Limestone of southern Calhoun County, Illinois and northern St. Louis County, Missouri was studied to determine first what corals were present and second the validity of the names assigned to the previously described species. It was found that the binomen for …

The Design And Calibration Of A Vibrating Sample Magnetometer, Donald Dwight Hoffman

Masters Theses

"The design and calibration of a vibrating sample magnetometer is described. The sample motion was in the direction of the external magnetic field which was produced by a superconducting solenoid. The maximum external magnetic field was 70 kilogauss. Sample temperature could be varied from 77°K to 1000°K with a vacuum jacketed furnace. The maximum temperature was obtained with approximately 27 watts. The instrument was calibrated to 1% with a spherical nickel sample"--Abstract, page ii.

Precipitation Of Carbon From Martensite In Ductile Iron, Devendra Ratilal Majmundar

Masters Theses

"Since metallographic studies of quenched and tempered cast iron have indicated that the carbon might precipitate directly as graphite rather than as carbides which are found in steels, this investigation used the Debye-Scherrer x-ray diffraction technique to examine electrolytically extracted residues from quenched and tempered ductile cast iron samples to determine if cementite was present. The precipitation of carbon in quenched samples of this ductile cast iron was found to be similar to the precipitation process in steels. Cementite was identified during the early stages of the tempering process when the tempering temperature was 800 degrees F, 900 degrees F, …

Structure And Chemical Composition Of The Otoliths Of Cyprinus Carpio, Larry Paul Coen

Masters Theses

"The need for the study of microfossils such as foraminifera, conodonts, and otoliths as stratigraphic tools has been well established. However, disarticulated parts such as otoliths and conodonts cannot be effectively used unless they can be recognized. Otoliths, although somewhat unrecognized in the geological record, are far more abundant than articulated skeletons (Frizzell, 1965, p. 86). Therefore, much investigation is being conducted to reveal the origin, function, morphology, and usefulness of the otoliths of fishes.

In this investigation, the asteriscus, well developed only in Ostariophysins (of which the carp is a member), is studied for morphology. New tentative terms are …

Attitude Scaling As A Public Involvement Tool In The Lower Mississippi River Region Comprehensive Study, William A. Lee

Masters Theses

"The planner is under considerable pressure to involve the public in water resource planning. The public, however, often lacks sufficient knowledge to offer useful comments or suggestions. The use of a Likert Type Attitude Scale in the public involvement effort of the Lower Mississippi Region Comprehensive Study demonstrates the usefulness of attitude scaling techniques in obtaining public input to the planning process. The measurement of an individual's attitude, or his thoughts, feelings and disposition to act toward some aspect of his environment with some degree of consistency, gives an indication of the goals and objectives toward which a plan acceptable …

Relative Volatility In The System 1-Butene - N-Butane, Steven Lewis Walker

Masters Theses

"An apparatus suitable for the rapid collection of P-x data at constant T is described. Isothermal P-x data at 40, 70, 100, 130, and 160 degrees Fahrenheit at the extremes of the composition range for the 1-butene - n-butane system are presented as a demonstration of the suitability of the device for its intended purpose. Limiting values of the relative volatility for the binary are presented. The relative volatilities were calculated using limiting forms of the general coexistence equation which are given in the literature. Several recommendations are given for improvements of the equipment and experimental technique"--Abstract, page ii.
