The Construction Of Two Light Sources With Adequate Intensity For Magneto-Optical Rotatory Dispersion Experiments, Norman D. Love

Masters Theses

Chapter I

Introduction

The phenomenon known as the Faraday Effect was discovered by Michael Faraday in the year 1845.¹ He discovered that when an isotropic substance of high refractive index is placed in a strong magnetic field which is parallel to a beam of plane polarized light, the plane of polarization is rotated. The rotation is proportional to H, the strength of the magnetic field; and to 1, the length of the light path in the sample. If X represents the rotation in minutes then

X = VH1.

The proportionality constant V is known as Verdet's constant. The units …

An Investigation Of The Genetic Basis Of Alcoholism, Daniel F. Malamud

Masters Theses

Introduction

Alcoholism: The Disease

"Alcoholism is a chronic disease manifested by repeated implicative drinking so as to cause injury to the drinker's health or to his social or economic functioning" (53). Such a definition of alcoholism points to the disease concept which went unrecognized until recent years. In addition to its medical implications, alcoholism has been the subject of considerable writing and research by academicians in such diverse fields as sociology, psychology, physiology, psychiatry, theology, and law.

At the outset it should be noted that the writer is aware of the arguments and opinions expressed by the advocates of the …

Comparison Of Alcohol Offenses Of College Students With Those Of Persons In A Similar Age Group Who Have Not Had College Experience, Cornelis Laban

Masters Theses

Introduction

The purpose of the study was to·make· a comparison of the drunk driving behavior of college students with that· of those persons in a similar age group who have not had college experience. There is very little published information about the statutes governing "driving under the influence of liquor" (D.U.I.L.). The educable nature of persons involved in such offenses 8 and the probable anti-social and sociopathic behavior in individuals leading up to the offenses, also need thorough investigation. Very pertinent also is the question whether or not there is a biological basis for this particular behavior; an understanding of …

The Reaction Of N-Magnesium Halides On Nitriles In The Synthesis Of Amidines, Robert Bauer

Masters Theses

Introduction

Compounds of the amidine class have long been of interest because of their therapeutic and pharmacological properties. Members of this class of compounds have been shown to be effective in combating pathological conditions ranging from virus (11), bacterial (12), and protozoal infections (7) to diseases of the circulatory system (6), neoplasms (5) and hyperglucemia (21), Since many basic nitrogen compounds have been of interest in cancer chemotherapy, such as a variety of amino alcohols shown by the Upjohn Company to have anti-tumoral activity, it was felt that additional investigations into the use of amidines and amino amidines in this …

The Dielectric Strength Of Some Anti-Corrosive Paints, George Albert Chappell Iii

Masters Theses

"Corrosion has been one of the costly problems to industry because each year losses due to corrosion are in excess of six billion dollars. Corrosion is caused by the tendency of all metals to become oxidized and return to their natural state. Oxidation may be suppressed by restraining the flow of electrons from the system, thereby inhibiting corrosion.

One effective means to prevent rusting is by applying a barrier of paint between the system and the corrosive atmosphere. Not all paints, however, are equally effective as corrosion inhibitors. At present, the only effective means of determining the corrosion resistant ability …

A Study Of Duffing's Equation, Charles Kirby Murch

Masters Theses

"The unforced cases of Duffing's equation and the equation of the simple pendulum are considered by imposing certain conditions on a linear partial differential equation. Geometrical arguments are presented which lead to solutions of the special cases considered.

Undetermined functions of integration in the solutions limit their use to the approximation of systems with small non-linearity"--Abstract, page ii.

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 …

Velocity Distribution Induced By Free Jet Impact On A Stilling Basin, Sedat Özkol

Masters Theses

"At present, the use of the free jet impacting on a stilling basin as an energy dissipator is not very common, as there is very little information available concerning this particular field. However, if conditions are favorable, this type of energy dissipator will be quite economical to construct.

In this paper it was found that the hydraulic behavior of the free jet impacting on a stilling basin can be determined to a degree which may be considered accurate for practical purposes. It was also shown that given the free jet velocity, the magnitudes of the velocities at the critical points …

Development Of A Simple Bar Method Thermal Conductivity Test, V. J. Flanigan

Masters Theses

"A linear flow bar method type apparatus was set up for finding thermal conductivities by comparison techniques. Comparison technique consist of using a standard specimen where the thermal conductivity is known and comparing it to the unknown specimens to find their conductivity. Apparatus of this type usually uses thermocouples for the required temperature measurements, but thermistors were used in this experiment. The thermistors used required calibration to measure accurate temperatures and this was accomplished by using the known temperatures of the changes of state of some common materials. Five alloys were used to evaluate the method: SAE 1020 steel, gray …

Foraminifera Of The Cenozoic And Recent Genus Sphaerogypsina Galloway, Wayne C. Horton

Masters Theses

"The morphology of Sphaerogypsina as seen in thin section affords various characters useful in classification] 1) arrangement and composition of the wall (calcareous-perforate, radially crystalline); 2) layering of wall (like Gypsina, without layering or black line, having only microlamellae); 3) shape of test (always spherical); and 4) specific characters: size of test, order/unorder ratio, size of chambers, wall thickness, pore diameter, and type of embryonic apparatus.

Correlation of the above characters has allowed recognition of two new species. Comparisons with other genera strongly suggest placing the genus in the Family Gypsinidae (nom. correct.) rather than in the …

Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

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

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."

The Experimental Determination And Prediction Of Ternary-Liquid Equilibria Data, Risdon William Hankinson

Masters Theses

"Although the field of liquid extraction is of increasing importance in today's chemical industry, the ternary-liquid data so necessary to the design and study of extraction operations are available in the literature only to a limited extent. During the twentieth century, approximately 120 ternary-liquid systems have been studied. However, limiting solubility data have been reported for approximately one-third of these systems, and about 30 per cent of the equilibria data reported for the remainder of these systems are incomplete or inaccurate.

Within limits, liquid equilibria data may be calculated for a ternary system from the properties of its constituents which …

Whatever method is chosen to determine the stress condition, there is no exact code that can be established to fit the various type problems which arise"--Abstract, page 1.

A Study Of The Chemical Kinetics, Activation Energy And Difference Effect On Beryllium Dissolving In Mineral Acids, Daniel Santhamurthi Gnanamuthu

Masters Theses

"The rate of dissolution of polycrystalline beryllium was studied in hydrofluoric, hydrochloric and sulfuric acids. Two samples of beryllium containing different amounts of beryllium oxide were used. The experiments were performed at temperatures ranging from 20 to 50°C, and at various acid concentrations. The kinetics of these heterogeneous processes conformed to a reaction order of approximately one in all the cases. Since the conditions of the surface were complex during dissolution, these might complicate the reaction. This might be due to the oxide layer, which is present as impurity.

The difference effect was determined at various acid concentrations at 25°C …
