A Pilot Study Of The Upper Pitch Limits Of Young Children As Measured By Psychogalvanic Skin Resistance Audiometry, Lawrence M. Smith

Masters Theses

The purpose of this study was to investigate the upper pitch limits of hearing in young children as a test of a hypothesis proposed by Fatsinger (1959).

According to the place theory of hearing, the low pitch sounds are located at the apex or wide part of basilar membrane, and are mediated by the long fibers, and the high pitch sounds at the basal or narrow part of the basilar membrane, and are mediated by the short fibers. Therefore, a size change which involved the basilar membrane could cause a shit in the pitch sensitivity range by producing longer fibers …

A Method Of Evaluating First Line Supervisory Training, Benjamin I. Killian

Masters Theses

Preface

This study is prepared to establish a method of evaluating supervisory training. An attempt to evaluate the following hypotheses will be considered: (1) There is a method of selecting the basic performance areas of a first line supervisor. (2) There are acceptable standards of performance in the basic area. (3) Performance appraisals prior to the introduction of training will determine sub-standard performance in the selected areas. (4) Follow-up performance appraisals will indicate the effectiveness of training in improving performance without undue contamination of the criteria by other influences.

During the study other areas of investigation to be examined are: …

Electrodeposition Of Antimony From Sulfide Melts, Mahendra N. Rana

Masters Theses

"A study of the current-potential relationships, and the electrodeposition of antimony metal was conducted for fused mixtures of Sb₂S₃-Na₂S, Sb₂S₃-Sb and Sb₂S₃-NaCl-KCl in the temperature range of 700° - 900°C. An attempt was made to determine the mutual solubility of molten antimony and Sb₂S₃-Na₂S melts. The microstructure of deposited metal was studied metallographically. Analysis of phases present in the matte mixture (Sb₂S₃-Na₂S) was made by x-ray diffraction patterns.

All investigations were carried out in …

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

A Study Of The Recrystallization And Polygonization Of High Purity Aluminum, Robert Leon Wright

Masters Theses

"Laue back reflection patterns were used along with visual examination in evaluating the characteristics of the annealed structure of high purity (99.99%) aluminum single crystals which had been deformed by elongation. It was found that the glide strain and annealing temperature are primary factors to be considered with respect to the structural changes occurring during annealing.

It was determined that the glide strain must be above a certain critical value to cause recrystallization; below the critical value polygonization will predominate in the annealed structure regardless of the annealing temperature.

The single crystals used in the investigation were grown by the …

Variation Of Sensitized Fluorescence With Penetration Depth Of Incident 2537a Radiation, George Grayson Robinson

Masters Theses

"An investigation of the sensitized fluorescence of a thallium and mercury mixture using a variable depth cell and photomultiplier type of detection is discussed. Data are given to indicate the variation of the intensity of the 3519A thallium line as a function of thallium temperature, as a function of mercury temperature, and as a function of cell depth. Explanations of results require the use of generally accepted ideas concerning energy transfer, emission, and absorption."

Detection Of Rust Formed Under Paint Films, James Larry Inglis

Masters Theses

"Corrosion is an evil that has plagued man since before the iron age. Three ways of controlling corrosion are: 1. alloy the metal to make it chemically inert to corrosion, .2. change the surroundings to a noncorrosive atmosphere, and 3. isolate the metal from the corrosive atmosphere, as for instance by the application of a number of coats of paint that has been found to be the most economical method.

At present, there is no reliable method of testing the effectiveness of a paint film that does not require the corrosion products to destroy the paint film and show themselves …

A Study Of Segregation In Cast Aluminum-Uranium Alloys, B. L. Bramfitt

Masters Theses

"This investigation involves a photomicrographic study of the segregation resulting from the eutectic solidification characteristics of aluminum-uranium alloys, ranging from 5 to 30 weight percent uranium. The segregation can occur in either of two manners; the first, due to the gravitational forces acting upon the growing particles which nucleate in the melt and the second, due to the mode and rate of heat transfer through the material. It was found that segregation occurred only as the result of the latter factor due to the small volume of the ingot and the rapid rate of heat transfer. The segregation was measured …

A Study Of Aging In An Old Order Amish Mennonite Community, Louise Chahbazi

Masters Theses

Introduction

The Old Order Amish Mennonites, undoubtedly the plainest of the "plain people," have a high regard for the beliefs and customs of their forebears. Their forefathers had no telephones, automobiles, electric lights, radios, or church buildings, so the Amish of today work the land with horses, travel in buggies, burn gas lights, gather in homes for worship services, and wear styles of dress which were common in seventeenth and eighteenth century Europe.

Estimates made on the basis of recorded church membership in the Mennonite Yearbook place the Amish population of the United States at approximately 57,000. Their high birth …

Predicted Transient Response Of Complex Poles By Means Of A Residue Ratio, Rameshchandra Shankerbhai Patel

Masters Theses

"Transient response plays an important role in servomechanism, electronic and electrical circuits. A time response of a linear system is the intuitive and immediately comprehensible description of the system performance. The utility of the system performance in television and high speed computer circuits can be determined by its transient characteristics. By locating certain points on the transient response curve the designer is enabled to predict the shape of the response with some precision. The choice of the overall transfer function (or location of the system singularities on the s-plane plot) is decided by speed, accuracy and stability of the response …

A Determination Of Vapor Pressure Of Barium In The Thermal Production Of Barium Metal, Thomas A. Theobald

Masters Theses

The Knudsen effusion method was used to find the equilibrium reaction pressure of barium for the following reactions:
4BaO + 2Al - 3Ba + BaO·Al₂O₃ (l)
4BaO + Si - 2Ba + 2BaO·SiO₂ (2).
The resulting barium pressure for reaction (l) ranged from 0.27 mm. Hg to 1.77 mm. Hg in a temperature range of 940°C to 1086°C. The barium pressures for reaction (2) varied from 0.38 mm. Hg to 1.94 mm. Hg in a temperature range of 1000°C to 1086°C. The free energies of formation of BaO·Al₂O₃ and 2BaO·SiO₂ at 1087°C …

Permeability Of Poly (Ethylene Terephthalate), James G. Harvey

Masters Theses

"Corrosion is a phenomenon which has been the subject of extensive research, in order to find a way to control or completely stop it. Two general methods, either placing the material which corrodes in an anti-corrosive atmosphere or protecting the material which corrodes from the corrosive atmosphere, are the chief means of preventing corrosion today.

The second method is probably most widely used presently. One of the most important methods of protection is by means of organic protective coatings, or paints, but at best these only retard corrosion, due to the fact that corrosive media e.g. water vapor, ions etc. …

Studies Involving Modification Of The Megregian Method Of Fluoride Determination And Application To Fluoride Balance Studies In Infants, Gene R. Wright

Masters Theses

Introduction

At the request of Dr. Frederick Margolis, M.D., and in association with The Upjohn Company, this research problem was initiated as a participation in the investigation of whether or not fluoride ingested as a constituent of the Upjohn 47-M liquid vitamin preparation is retained in an infant's body to the same extent as is fluoride ingested as the sodium salt by itself--either in solution or in tablet form. The retention patterns may be studied indirectly by measuring the amounts of fluoride excreted in the urine and in the feces during each of a series of equal time intervals after …

Thermal Conductometer For Liquids, Yuan-Kai Chang

Masters Theses

"The published data pertaining to the thermal conductivity of liquids are of such a character that it is very difficult to determine from them the correct value, or the temperature coefficient for any liquid.

Most of the published values of thermal conductivity for liquids are evaluated at one particular temperature. It is the purpose of this investigation to design, construct and calibrate a thermal conductometer for liquids over a temperature range of 30°F to 200°F.

Since water and glycerol were the only liquids found by this investigator with published data on their conductivities as a function of temperature, they were …
