Geology Of The Copper Deposits In The Eminence Region, Shannon County, Missouri, Lanny Lee Evans

Masters Theses

"Copper has been known to occur in Shannon County, Missouri since the early 1830's. A number of small deposits in an area around Eminence has been worked intermittently up to the present day. Little detailed geologic information is available on these deposits. The geology of the Eminence region consists of Precambrian rhyolite porphyry knobs projecting through dolomites and sandstones of Upper Cambrian and Ordovician age. A conglomerate of limited horizontal extent overlying the Precambrian is found at certain localities within the region. The only structures noted are the structural highs formed where the Paleozoic sediments lap upon the knobs. The …

The Effect Of Rare Earth Additions On Low Alloy Steel, Sukh Dev Sehgal

Masters Theses

"Rare earth metals have for some years been used as an inoculant in nonferrous foundry practice and lately in the production of nodular iron. It has been reported that addition of rare earth metal to certain grades of stainless steel so improve the hot malleability that reduction of large size ingots in the blooming mill is now possible. It has been reported that considerable improvement in soundness and mechanical properties of steel castings and wrought products have been attained as a result of small additions of rare earth metals and oxides. In practically all investigations, it has been reported that …

Mechanization Of First Stage Graphitization In Fe- C-Si- Alloys, Dildar S. Gill

Masters Theses

"The purpose of this investigation was to study the mechanism of first stage graphitization in iron-carbon-silicon alloys in the light of results obtained by Taub, and to propose a new mechanism of graphitization. The results of preliminary experiments confirmed the findings of Taub as regards the precipitation of secondary carbides. Therefore, it was decided to extend the investigation so as to include the study of growth of secondary carbides. In order to know the chief factor responsible for the growth of secondary carbides, the activation energy was calculated. Another factor which was investigated was the site of graphite nuclei formation”--Purpose …

X-Ray Diffraction Study Of The Metal Powder Compacts, Rajendra Sharan

Masters Theses

"Various theories have been put forward about the mechanism of compacting and sintering processes. None of these theories are confirmed. The reason is that most of these theories are based on observations on metallographic specimens, which is not a particularly good tool for such a study. Little data using xray diffraction analysis is available and there seems to be a great need of making a thorough investigation in this direction.

The main object of this investigation is to study xray diffraction patterns of green compacts of aluminum, nickel and copper powders pressed under different compacting pressures to see if any …

An Experimental Investigation Of A Small Volume Sandwich Antenna In The 400 Megacycle Frequency Range, James Gilbert Smith

Masters Theses

"Scope of the Investigation: The small volume sandwich antenna was patterned after that of F. D. Clapp's which appears in an unpublished report written for the United States Navy. Clapp's antenna is shown in Figure 2. The antenna described in this report was investigated at approximately one-thousandth of the volume of the original Clapp antenna. Clapp's antenna was designed for the 225-400 megacycle range; while the author's model was designed for operation at 400 megacycles.

The objective of this investigation was to build a small volume sandwich antenna which could be adapted to satisfy the characteristics listed on page 1. …

Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes

Masters Theses

"The purpose of this investigation was to determine the influence of the rate of loading variable on the apparent shear strengths of joints bonded with some of the currently available metal-to-metal adhesives. The effects of this variable are sometimes neglected by testing laboratories. The results of an experimental evaluation of the mechanical behavior of a group on modern metal-to-metal adhesives as a function of the rate of load application are used to more accurately establish the importance of rate of load considerations in adhesive joint testing. An attempt is made to explain observations of other investigators engaged in adhesive joint …

Masters Theses

"The following study consisted of two problems. One was the design and construction of an automatic antenna pattern plotter, and the other was the design of a microwave absorbing material for use in a darkroom"--Introduction, page 1.

Stabilization Of Swelling Clay Soil By Additions Of Calcium Hydroxide And Calcium Oxide, Anthony Diler

Masters Theses

"As a study of all types of stabilization would be very lengthy, it was decided to make the object of this research the determination of the effect of the addition of different percentages of calcium oxide (CaO) and calcium hydroxide Ca(OH)₂ on the physical characteristics of a silty swelling sodium montmorillionite clay. The purpose of this addition is to flocculate the clay by utilizing a base exchange between the sodium and calcium ions, and thus change the physical characteristics of the soil. The soil by itself has the characteristics of a fat clay, that is it can be broken …

Steady State Temperature Distribution In A Rotating Disk, George Henry Morgan

Masters Theses

"The purpose of this investigation was to obtain an expression for the steady state temperature distribution of a disk of uniform thickness rotating at a constant speed in ambient air while absorbing heat through the periphery at a constant rate. Engineers encounter such problems in connection with brakes of several varieties. The general solution obtained here could be extended to similar physical problems such as grinding wheels, disk clutches, and so on.

A differential equation was obtained for the temperature in the disk by the application of Fourier's conduction law and Newton’s convection law. A solution of this equation was …

Effect Of Alkaline Earth Chlorides On Vapor-Liquid Equilibria Of Acetic Acid-Water System, James F. Carnahan

Masters Theses

"In the separation of a system of liquids by distillation the ease with which they may be separated is most clearly indicated by the relative volatility; the greater the value of the relative volatility, the greater the ease of separation.

A system that contains compounds whose boiling points are spread over a relatively small temperature range is not readily separated by distillation. The addition of a substance that reduces the vapor pressure of one of the components, while having little or no effect on the others, adds to the ease of separation and consequently would decrease the initial size and …

Permeability Study Of Algal Reef Beds Within The Bonneterre Formation, National Mine, St. Francois, Missouri, Bobbie L. Perry

Masters Theses

"The Missouri "Lead Belt" comprises approximately 50 square miles, centering around the town of Flat River, in St. Francois County. Missouri. This district has been producing lead for more than 200 years, the total production being at least 8,000,000 tons of lead, valued at more than $1,000,000,000. For many years, the annual production of the district has been at least one-fourth of the total production in the United States.

An excellent description of the geology of this area was published recently by Ohle and Brown in 1954.

The ore consists principally of galena which is disseminated within the Bonneterre formation …

Performance Characteristics Of A Tubular Regenerative Heat Exchanger, Harry J. Sauer Jr.

Masters Theses

"The term regenerator is widely used to define any type of heat exchanger in which the heat is alternately stored and removed...The present investigation is concerned with the calculation of the characteristics of the "single-blow", tubular regenerative heater, its dimensions and performance. In the analysis in this thesis, the heat is considered to be stored in bundles of tubes initially preheated by hot gases flowing through the heater and subsequently cooled by the flow of air. This paper makes no attempt to deal with the effects of radiation from the outer row of tubes to the heater shell"--Introduction, page 1-3.

Effect Of Gamma Radiation On Selected Organic Protective Coatings, James W. Johnson

Masters Theses

"The purpose of this investigation was to prepare pigmented and non-pigmented organic protective coatings and to irradiate them with gamma rays. The coatings received a constant radiation dose of eight million rads. Seven tests were performed on the various coatings. The data from the tests were tabulated so that a direct comparison could be made as to the effect of the radiation on the coatings. The data from the tests also enabled comparisons to be made to determine if the various pigments had imparted any specific properties that would be desirable in coatings being exposed to radiations"--Introduction, page 2.

The Use Of Chelating Agents In Inorganic Analysis, Richard K. Vitek

Masters Theses

"The objectives of this investigation were; (1) to improve the existing gravimetric method of analysis for palladium with dimethylglyoxime by adding EDTA to the solution to chelate interfering metal ions: (2) to develop a new and better gravimetric method of analyses for palladium with a different organic ligand and employing a chelating agent such as EDTA or NTA to remove the interference of foreign ions"--Introduction, page 2.

Reconstruction Of A Model L Podbielniak Fractional Distillation Apparatus, Raymond Bauer

Masters Theses

"The purpose of this thesis was to reconstruct a Model L Podbielniak Fractional Distillation Apparatus to provide equipment suitable for the study of batch multicomponent distillation.

The properties chosen for comparison were: (1) liquid limit, plastic limit and plasticity index; (2) shrinkage limit and shrinkage ratio; (3) density and optimum moisture; (4) resistance to penetration; (5) compressive strength and (6) cohesion and angle of internal friction. In order to …

The Analysis And Evaluation Of Supervisory And Managerial Personnel, Robert A. Huston

Masters Theses

Introduction

The rapid growth of American industry during the first half of the Twentieth Century has brought managements face to face with the necessity to delegate responsibility and commensurate authority to the various echelons of the supervisory and managerial personnel. The owner-manager era is a thing of the past. Gone with it is the intimate relationship that once existed between the owner of the business and those who worked for him. In its place has arisen the corporation, a statutory entity that cloaked ownership with impersonality.

Coincidental with the change of character of ownership and, indeed, one of the major …
