Temperature Distribution In An Infinite Plate As A Function Of The Input Heat Flux, George Franklin Wright

Masters Theses

"It is the purpose of this thesis to investigate the effects of a variable input heat flux impinging equally on both sides, on the temperature distribution within an infinite plate. An infinite plate may be defined as one in which the dimensions are infinite in two directions and finite in thickness. For practical purposes such a plate could be thought of as one in which the thickness was small enough, compared to the other two dimensions, so that a temperature gradient exists only normal to the surfaces of the plate. This assumption will be made to establish one-dimensional heat flow …

Factors Of The Microclimate Affecting The Activity Of Fox Squirrels In Southwestern Michigan, Frederick K. Courville

Masters Theses

The fox squirrel, Sciurus niger rufiventer, is an important small game animal throughout much of the Midwest. Within the last thirty years several scientific investigations have been focused on this animal, the result being that its life history and ecology are fairly well known.

Concerning the range of the fox squirrel, D. L. Allen (1943:33) states that, in Michigan, the range began to increase with the advent of the pioneers. Baumgartner (1940) and J. M. Allen (1952) noted similar occurrences in their respective states, Ohio and Indiana. In Kansas, the fox squirrel, aided by agricultural land-use, has spread westward throughout …

Community Driver Education: A Study Of The Driver Education Program Of The Kalamazoo Area Safety Council, Milton J. Marovich

Masters Theses

Chapter I

Introduction

The Study and Its Background

In educating for life adjustment in the highly technological culture existent in this country, it is necessary to recognize the role of safety education. More recognition, however, will not instill the proper attitudes, habits, and physical skills necessary for safe and healthful living. Among all the need for safety education, the operation of a motor vehicle is only one area of concern to the safety-minded. But, to the citizenry it is perhaps the most cogent concern in as much as the consequences of unsafe acts involving use of the motor vehicle are …

Gladstone, The Irish Home Rule Question, And Its Effect On The Liberal Party, Kenneth John Van Dellen

Masters Theses

Introduction

Purpose

The Victorian Age of English history produced many great political leaders. Among the best known are Chamberlain, Disreali, Palmerston, Salisbury, and Gladstone. These politicians were able to pacify many dissatisfied groups and produce many reforms. Yet one of the biggest problems they had to face was left unsolved throughout the Victorian period, and the later Edwardian period as well. This problem was Ireland.

This research project will deal with the man who made one of the most persistent efforts of the nineteenth century to solve the Irish problem. It will attempt to show how William Ewart Gladstone become …

Beliefs And Attitudes Of Recent High School Graduates On The Subject Of Beverage Alcohol, Francis E. Chape

Masters Theses

Introduction

During recent years, many investigations concerning the teen-ager and beverage alcohol have been carried out. A survey of the available literature on this subject revealed that most of the studies have been made to determine the attitudes toward drinking and the drinking behavior of this age group. These studies, Maddox¹ states, provide "The basis for generalizations about drinking in high school which are more substantial than impressionistic guesses."

Generalizations, however, have not been limited to drinking behavior alone. Alcohol education programs, required by law in every state in the union,² have received much criticism in recent times. …

Segregation Method As Possible Process To Beneficiate Oxidized Lead Ores, Jose Molfino Tomasio

Masters Theses

"In this investigation it has been demonstrated that the Segregation Process has merit for treating oxidized lead ores.

The process comprises heating the crushed ore with salt and coal at about 750° C. to produce metallic lead attached to the carbon particles, which then is recovered by conventional flotation methods.

The quantities of sodium chloride and coal required for the best segregation of lead obtained in this work was 1.0 percent of coal and 1.0 percent of salt by weight.

Good segregation was obtained by using salt and coal as fine as 65 or 48 mesh. Segregation varied with the …

Business-Sponsored Films For Physical Science, Bertha Elizabeth Slye

Masters Theses

For many years business-sponsored films have been used widely in instruction in the science classroom. Because of the potential of the films in helping teachers bridge the gap between the fundamental teaching of scientific principles, and the applications found in the actual experiences of the student's consumer world, requests for them have often exceeded the output of those that are educationally sound. In the last decade in particular, the development of atomic and space technology, as well as the growing interest in science, have made it necessary to teach science beyond the confines of information in the ordinary science textbook. …

Effect Of Leaching On The Strength Properties Of A Hydrated Lime-Cement Stabilized Soil., Yurdakul Osman Ulugonul

Masters Theses

"The stabilization of soil has been carried on since early historic times. The Romans used lime and volcanic ash as additives for this purpose. After the discovery of cement and its property of bonding soil particles it became one of the essential additives in the soil stabilization field. Many other kinds of additives have been developed and are being used today for soil stabilization.

A question that arises through the increasing use of stabilizers in soil is whether the changes that are effected are of a temporary or permanent nature. Changes may occur from the degradation of the stabilized soil …

Deflections Of Two-Way Slabs, Gerald C. Godzwon

Masters Theses

"A reinforced concrete member is by no means a truly elastic member, hence all ordinary deflection calculations relating to it, whichever method, are approximate. By the use of model study actual reinforced concrete slab models, of different end conditions, were built and tested for deflections under uniform loadings. Theoretical and actual deflection of reinforced concrete slabs are compared. The results of these tests indicate that the theoretical deflection equations may be 60 to 80 percent in error when applied to reinforced concrete slabs"--Abstract, page 2.

Some Dynamic Creep Characteristics Of Gypsum, Ikram-Ul-Haq Dar

Masters Theses

"A review of literature concerned with time-dependent deformation of geologic and non-geologic materials is presented. A static loading machine and a four unit dynamic loading unit was designed and assembled to evaluate static and dynamic creep properties of gypsum. The tests were run for various levels of static loads, and superimposed dynamic loads. Investigations were carried out to determine the relationships, if any, between impact energy, impact velocity and momentum, and dynamic strains. Viscoelastic coefficients were determined for the investigations. The conclusion was presented that time-dependent strain in the dynamic creep tests of the particular gypsum rock tested is a …

Methods For Calculating The Minimum Amortization Tonnage And Maximum Present Value For An Ore Body, Garrett M. Sainsbury

Masters Theses

"The discussion is divided into three parts. Part I describes a procedure for determining the mining rate that gives the minimum amortization tonnage required of an ore body, and the amount of that tonnage. The basic idea is that amortization tonnage is equivalent to the estimated capital costs, including interest, divided by the estimated operating profit per ton. Both capital costs and operating profit per ton can be expressed as functions of mining rate by making use of empirical equations. Therefore, amortization tonnage can be expressed as a function of mining rate. The amortization tonnage is calculated for a series …

The Redesign And Construction Of A Rotating Disc Contactor, Richard Henry Okenfuss

Masters Theses

"Liquid-liquid extraction has played a major role in the processing of nuclear fuels. The Department of Chemical Engineering of the Missouri School of Mines and Metallurgy realizing this, petitioned the Atomic Energy Commission for funds to design and construct an instructional facility representing the chemical processing of nuclear fuels. With this unit and its solvent recovery equipment, in which stress is placed on extraction and distillation, not only are the principles of nuclear fuels processing demonstrated, but the more basic concepts of mass and energy transfer are also illustrated. Extraction depends upon solubility differences to achieve a transfer of a …

Determination Of Vapor-Liquid Equilibrium Data By Continuous Distillation, David William Bunch

Masters Theses

"The procuring of experimental vapor-liquid equilibrium data has been a problem of considerable importance to chemical engineers for a number of years. Modern distillation theory and practice have made accurate vapor-liquid equilibrium data practically a necessity.

Using conventional methods for determining vapor-liquid equilibrium data, an experimenter can obtain only a single vapor-liquid equilibrium composition per trial. Ramalho working with Tiller has developed a new method which makes possible the determination of all values of the vapor and liquid concentrations in a single experiment.

The work done by Ramalho indicated that the necessity for very precise temperature measurements presented a serious …

The Effect Of The Rare Earth Elements On The Hot Workability Of Ingot Iron, L. A. Neumeier

Masters Theses

"The effect of mischmetal and rare earth oxides on the hot workability of ingot iron in the hot-short region was studied. Thirteen heats were melted in air in a basic-lined induction furnace. All heats were thoroughly deoxidized with aluminum prior to the rare earth additions. Mischmetal was added in amounts of 0.1, 0.3 and 0.5 per cent. Rare earth oxides were added in amounts of 0.1 and 0.2 per cent. Temperatures were maintained at approximately 2900°F and holding intervals between mischmetal additions and pouring at two minutes. Bars were hot rolled and swaged for hot twisting in the hot-short region. …

Oxygen Permeability Of Free Paint Films, Janice I. Kellerman

Masters Theses

"As early as the mid 1800’s investigations were performed on the gas passage through rubber, but it is only comparatively recently that plastic polymeric materials have come into prominence. One interesting aspect of much experimentation begun was that of permeability, and it was soon evident that, in general, polymeric materials have extremely low permeability of gases. This is, in essence, the basis for use of plastics as packaging materials, balloons, and in many other designs and fabrications where it is desirous and/or necessary to exclude air.

There are several variables which must be taken into consideration in the evaluation of …

The Separation Of Selected Radioactive Fission Products By Electrodialysis, Jerry David Vie

Masters Theses

"The recent advent of nuclear energy has opened an era of almost unlimited power and countless problems. A problem of extreme importance is the recovery of unburned nuclear fuel and the claiming of transmutation products, such as Pu²³⁹ and U²³³, from the irradiated fuel elements. The chemical processing must also separate the fission products from the fissionable material if the fuel is to be used again.

At present, the irradiated fuel elements are stored for 90 to 120 days to allow the intense short half-life activity to decay. After "cooling down", the nuclear fuels are separated from …

Physical Property Tests Of Rock, Centrifugal Tests And The Design Of Underground Mine Openings, Samuel Shu Mou Chan

Masters Theses

A Method For The Prediction Of Detection Ranges For Pulsed Doppler Radar, Phillip Orlan Brown

Masters Theses

"Modern radar systems must provide greater detection ranges both against high and low altitude targets because of the significant advances in weapon speed and range. Extended range indicates that the power transmitted by the radar must be increased. It follows, that ground return becomes a problem even at high altitudes.

There are at present three basic types of radars which are (1) pulsed, (2) continuous wave, and (3) pulsed doppler radar. The conventional pulsed radar now closely approaches the theoretical optimum performance; however, it does not have the inherent ability to distinguish between ground return and moving targets. The continuous …

A Dissolution Rate Study In Hydrofluoric Acid Of Titanium And The Alpha Solid Solutions Of Oxygen In Titanium, John L. Ratliff

Masters Theses

"The dissolution mechanism of titanium in hydrofluoric acid was studied by collecting the hydrogen evolved during the dissolution reaction. A concentration range of 0.05 N to 0.50 N and a temperature range of 15°C to 45°C were employed for the determination. Values of the reaction order and energy of activation were determined for both pure titanium and the alpha solid solutions of oxygen in titanium and found to be the same within experimental limits. This indicated that the reaction giving rise to hydrogen evolution on the surfaces of both pure titanium and the TiO_x alloys was the same. The …
