The Development Of Collective Investment Funds For Bank Trust Departments, Floyd L. Parks

Masters Theses

Introduction

In recent years the policies of many of our financial institutions have changed to meet the public demands and the degree of competition. It hasn't been too many years ago when most bankers felt that an automobile loan should be repaid in 24 months rather than the 36 month period which is now common. Some lenders today are even offering a 42 month repayment period. It wasn't too long ago when most banks were paying 2 1/2% on their savings accounts while the standard rate now is 3%, with most banks offering an even higher rate of 4% for …

Christianity Encounters Totalitarianism In Germany, Viola M. Gross

Masters Theses

First paragraph:

The German Church of the twentieth century offers a unique opportunity for study. It has twice faced a totalitarian government and has needed to learn to exist and carry on its witness to the Word of God in the face of almost insurmountable obstacles. The purpose of this paper is to contrast and compare the answer of the Church and the Christian to the National Socialists and to the Communists in East Germany, and to determine if possible if Christianity has learned the way through its desperate struggle in this century to continue its task under a hostile …

An Investigation Of The Visual Processes Involved In The Vertical-Horizontal Illusion, Robert L. Vette

Masters Theses

The vertical-horizontal illusion has been the object of experimental study for many years. The first man to investigate the vertical-horizontal illusion was probably Oppel in 1854. Since the time of Oppel's first experiment, many theories have been advanced in an attempt to explain what causes this illusion to occur in our perception of connected vertical-horizontal lines. The primary theory that is most widely accepted states that the vertical line in the "T" illusion will be judged longer because of the vertical-horizontal relationship.

Pan (1934) suggested that the "T" figure illusion was not due entirely to the interaction of the vertical …

Pachycereus Marginatus Alkaloids, John M. Brewer

Masters Theses

Introduction

Serturner's paper, 1817, "Morphis, a New Salt-forming Substance, and Meconic Acid, as the Chief Constituents of Opium", opened a new era of discovery in organic plant chemistry. His isolation of the first alkaloid was soon followed by the isolation or narcotine by Robiquet and strychnine by Pelletier and Caventou. These basic compounds were at first called vegetable alkalies, but were later renamed alkaloids, meaning alkali-like¹¹.

Aging Of The Dielectric Properties Of Some Perovskite Ceramics, Hector Troche-Maldonado

Masters Theses

"The effect of aging upon the dielectric constant and the dissipation factor were investigated for a number of lead titanate zirconate ceramics of varying composition. The ceramics investigated have a perovskite type structure. The materials chosen all have tetragonal symmetry at room temperature but are close in composition to materials of rhombohedral symmetry.

Empirical relations were determined for each specimen giving the rate of aging of the dielectric constant (K) and loss factor in terms of the frequency (f) and the elapsed time (t). The range of frequency was l kcps to l mcps; the range of elapsed time was …

The Indole Acetic Acid Oxidase Of Hygrophorus Conicus., Dilip N. Patel

Masters Theses

"The purpose of this investigation was to determine an assay method for measuring the activity of the indole acetic acid oxidase present in Hygrophorus conicus. This enzyme converts tryptamine or indole acetic acid (IAA) into oxindole acetic acid (OIAA).

An assay method for measuring the activity of the enzyme was developed based on the spectrophotometric measurement of tryptamine, IAA, and OIAA. Several other assay methods were tried. The colorimetric method of Gordon and Weber ^(l4) was found to be useful for a quantitative determination of IAA and was insensitive to OIAA. Paper chromatography proved to be useful as a qualitative …

The Anodic Dissolution Of Cadmium In Aqueous Solution, Yun-Chung Sun

Masters Theses

"The increasing importance of prevention of corrosion in industry has stimulated extensive studies on the fundamental behavior of metals in corrosive media.

The basic mechanism of the anodic dissolution of metals such as cadmium, magnesium, and zinc in salt solutions is not completely known. Several mechanisms have been proposed by different investigators, but evidence is still lacking to draw unquestionable conclusions to explain the discrepancies which often arise between coulometric data and weight loss of metal electrodes in certain salt solutions.

The purpose of this investigation was to obtain experimental data for anodic dissolution of cadmium in various electrolytes and …

Radiation Characteristics Of A U-Slot Antenna., Richard Paul Brueggemann

Masters Theses

"The radiation equations for a simple rectangular slot antenna are derived as a function of the field distribution in the slot. The electric field distribution in the slot is then formulated as a function of the aperture dimensions. The U-shaped slot antenna is described as an extension of the rectangular slot theory and the actual field is measured in the slot for comparison.

The far field equations a.re derived for the U-slot antenna similar to those for the rectangular slot antenna and are evaluated using the formulated distributions in the slot for antennas of two different electrical sizes. The equations …

Microscopic Observations On Etched Surfaces Of Zinc Single Crystals And On Anodic Disintegration., Yun Wang

Masters Theses

"The technique used to grow single zinc crystals was based on the Bridgman method. Zinc-gold, zinc-aluminum, and zinc-magnesium alloys were prepared and their single crystals were grown. Four crystallographic planes of the single zinc crystals were used for both chemical and anodic etching. The zinc alloys were etched more easily by acids than the purest (99.999%) zinc. The etching patterns changed for the different crystallographic planes of the single zinc crystals.

The appearance of particles during anodic dissolution of the single zinc crystals depended on time, acid concentration and current density. The partial disintegration of single zinc crystals is promoted …

Masters Theses

"The extensive application of synthetic organic pesticides in the United States has created many problems, particularly with respect to fish life. While a number of investigations have been undertaken to determine the toxicity of several pesticides to various species of fish, a great deal of research work is needed before the problem is completely understood.

The individual toxicities of DDT, BHC, 2.,4-D, and Sevin to western golden shiners were determined by means of the bioassay procedure at a t empera t ure Of 16oc. The four chemicals studied were found to be toxic to the test fish with Median Tolerance …

Estimating Bench Design Parameters For Open-Cut Excavation, Rajni K. Gandhi

Masters Theses

"There are no direct relationships available that provide a basis for bench design of multiple-bench, open-cut earth excavations in competent materials when power shovels are employed. This study was undertaken to determine if mathematical design expressions could be developed when the production rate, material's properties, and equipment operating characteristics were known.

It was found that all bench dimensions were a function of the bench height, which in turn was controlled by the required rate of production. The investigation revealed that suitable relationships could be developed to guide in the control of bank stability, choice of shovel capacity, determination of the …

The Anodic Dissolution And Disintegration Of Gallium And Aluminum And The Initial Valency Of The Ions Entering Aqueous Solutions., Kenneth Anderson Poush

Masters Theses

Gallium dissolved very slowly in dilute acids like HC1, H₂SO₄and HCIO₄. The rate was substantially accelerated if the metal was connected with a platinum electrode in the same solution. From the volume of the hydrogen developed the trivalency of gallium ions going into solution was calculated. This same ionic charge was obtained from coulometric measurements using gallium-amalgam as the anode. The initial ionic charge of aluminum dissolving from an aluminum amalgam anode was evidenced as being plus three by coulometric measurements.

Gallium and aluminum anodes were found to partially disintegrate while the current flowed. …

Masters Theses

"The tie line connecting the compounds 3CaO·Al₂O₃ and Na₂O·8CaO·3Al₂O₃ in the ternary system CaO-Al₂O₃-Na₂O was studied at 1250° Celsius.

It was determined that Na₂O can exist in crystalline solution with 3CaO·Al₂O₃ in percentages of about 2.3% or less without any apparent change in the structure of 3CaO·Al₂O₃. X-ray diffraction peaks in the back-reflection region shifted to lower d-spacing values on increasing Na₂O contents.

At a Na₂O content of about 2.7%, each major x-ray …

A Study Of The Separation Of A Mixture Of Carbon Dioxide And Hydrogen By Means Of An Orifice., Larry Gene Bauer

Masters Theses

"The purpose of the investigation was an attempt to verify a statement made by Partridge in an effort to discover a new method of separating gaseous mixtures. Partridge stated that when a constant pressure is applied on two gases of different specific gravity, a larger volume of the l igl1ter gas is forced through the orifice. Orifices of 1.016, 0.319, and 0.222 millimeter in diameter were used in the course of the investigation.

It was found that with the apparatus used in the research endeavor, no separation of the mixture of hydrogen and carbon dioxide could be obtained"--Abstract, p. i

Ignition Time Lag: A Measure Of Explosive Energy Release, Paul H. Rydlund

Masters Theses

"By means of the resistance-element, or probe-wire, detonation-velocity measurement technique, explosive reactions from various blasting agents were studied. To reduce the number of variables, only standard AN-FO 94/6 mixtures were used, as are commonly employed today in constructions and mining operations. Accuracy of the data obtained was excellent, and the method proved itself not only relatively simple to operate but versatile in providing considerable information under many testing conditions. Studies of test records revealed the presence of a time-lag frequently occuring [sic] after primer detonation. Environmental factors such as confinement, charge diameter, primer size and energy content, and surface coatings …

Structural And Magnetic Characteristics Of The Belton Anomaly, Cass County, Missouri, Nagib Chamon

Masters Theses

"A vertical intensity magnetic survey of approximately 156 square miles in Cass County, central-west Missouri, revealed a broad circular anomaly whose magnetic relief exceeds 1000 gammas. Surface rocks are very gently inclined and are of Pennsylvanian age. Crystalline basement rocks are at a depth of approximately 2400 feet. Analysis of the data shows that the Belton anomaly consists of discontinuous smaller magnetic anomalies surrounding the central part of this broad anomaly. The central area of the Belton anomaly is occupied by a magnetic low. Analytical calculation showed that the source of the magnetic disturbance is at least 3650 feet below …

Thermal Resistance Of Bonds And Contacts, David Marion Lewis

Masters Theses

"The adhesive and sealant Industry has more than kept pace with our rapidly expanding technology of today. This growth has left the standardization of data on adhesives far behind and lack of this data is obvious. Of the many applications, particularly as related to space technology and energy conversion, the resistance to the flow of heat offered by the bond layer is of considerable importance.

Little information is available on the effect of adhesives on heat transfer. In connection with their work on honeycomb panels, Rankle, Gier, and Bevans (7) determined the thermal resistance of the particular type of adhesives …

Compensator Design For Unity Feedback Systems Using An Analytical Method, Chang-Yu Wu

Masters Theses

“In control systems engineering it is frequently necessary to compensate a fixed plant whose transfer function cannot be changed. Usually the characteristics of the resulting system are established in terms of steady-state and transient performance specifications. Generally it is necessary to insert a compensator which insures stability as well as satisfies the specifications.

In this thesis an analytical method is developed to determine the transfer function of the compensator in order to satisfy the following set of specifications. The fixed system is assumed to contain one non-linearity, saturation. The input to the saturable device is constrained in a statistical …
