A Model For X-Ray Scattering From A Free-Volume Liquid, Charles A. Hewett

Masters Theses

"Investigation of the diffraction of x-rays by liquids was begun soon after the well-known work of Friedrich, Knipping, and Laue proved to be of value in supplying information as to the arrangement of atoms in crystalline matter. Friedrich in 1913 reported x-ray diffraction patterns of Canadian Balsam, paraffin, and amber; three years later Debye and Scherrer, in their work on benzene, (among other liquids investigated) showed that the diffraction phenomenon exhibited was one of interference. Still later, in 1922, Keesom and de Smedt reported similar investigations carried out on argon, nitrogen, and oxygen in the liquid state, the results of …

Geology Of The South Half Of The Meramec Spring Quadrangle, Missouri, Howard Joseph Yorston

Masters Theses

"This report is a continuation of the work initiated by Mueller in his mapping of the north half of the Meramec Spring Quadrangle. The completion of this work provides not only a geologic map of the whole quadrangle but also completes the mapping of the geology of a strip of quadrangles extending from Rolla to the Mississippi River. In addition to being a step closer to the goal of complete geologic coverage for the state, this work will be of value to those concerned with the prediction of depths of wells drilled in search for water, which in view of …

The Velocity Of Ultrasonics In Liquids, Mack A. Breazeale

Masters Theses

"In acoustics the term ultrasonics is used to refer to those frequencies which are above the range of human hearing; that is, frequencies above approximately 20,000 cycles per second. Since the laws of sound which are valid for the audible range are also valid in the ultrasonic range and since the wave length of ultrasonics is much shorter than that of audible sound, ultrasonic has proved very valuable in the calculation of both the velocity and the absorption coefficient of sound in various media. This is especially notable in the case of liquids, where the velocity of sound is much …

Mechanism And Measurement Of First Stage Graphitization In White Cast Iron, David S. Gould

Masters Theses

"The original object of this thesis was to ascertain if coercive force measurements could be used for the determination of degree of malleablization in malleable iron. Since first stage graphitization was involved, it was only natural that an interest in the mechanism of first stage graphitization developed. The investigation which resulted from this interest was done primarily for the edification of the author, however it was subsequently deemed of enough importance to be included in this thesis. For this reason the thesis may appear at times to deviate from the original objective"--Preface, page iii.

Coloration Of Glass By High Energy Radiation, Thomas L. Nickens

Masters Theses

"Purpose of Investigation: One of the objects of this investigation is to determine the amount of CeO₂ required to prevent the discoloration of glass when exposed to gamma radiation. By discoloration, it is meant that there has been a change in the absorption bands of visible light. Another objective is an attempt to prevent the coloration by the introduction of two oxides not previously used. Finally, a theory is presented which could explain why glass containing CeO₂ does not change color upon irradiation by gamma rays"--Introduction, page 1.

Determination Of The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Harold Robert Weisbrod

Masters Theses

"The purpose of this research is to investigate possible methods of determining the thermal conductivity of small poorly conducting samples at elevated temperatures, and, further, to assemble a suitable apparatus, followed by measurement of thermal conductivity of one or more cubic lattice samples.

Basic requirements of the apparatus are few. It is first required that the measurement of thermal conductivity be made over a considerable range temperature. It is also preferred that the basic apparatus be placed in a vacuum where undesirable heat flow by convection is eliminated and air corrodible samples are preserved.

The apparatus must use only the …

A Study Of The Emission And Absorption Spectra Of Nacl And Kcl Between 100 A And 1000 A, Paul Henry Blackmon

Masters Theses

"This investigation was begun with the idea of obtaining the emission and absorption spectra of NaCl and KCl in the region between 100 A and 1000 A. From these data, it is hoped that useful information concerning the energy levels of these two substances may be obtained.

The vacuum ultraviolet region is rather difficult to investigate because of the necessity of removing all air, lenses and other absorbing material from the light path. Many writers have enumerated the problems involved and some have indicated that much work still needs to be done in the vacuum ultraviolet.

In order to do …

Foraminifera Of The Type Section Of The Archusa Marl Of Mississippi (Eocene, Claiborne Group, Wautubbee Formation), Nathan Eugene Crockett

Masters Theses

"The type locality of the Archusa marl member of the Wautubbee formation is situated south of Quitman, Clarke County, Mississippi. Stratigraphically, the unit falls within the middle Eocene Claiborne group, being roughly equivalent to the upper part of the Lisbon formation of Alabama and the lower part of the Cook Mountain. The marl falls within the Ostrea sellaefonnis zone and the zone of "Ceratobulimina eximia.” The type section consists of 48 feet of sandy marls, with a thin oyster bed near the middle.

The Archusa foraminifera fauna consists of 87 species and varieties, belonging to 49 genera and …

The Mineralogy Of The Grassy Creek And Saverton Formations, Dirk Pieter Van Duym

Masters Theses

"A study of the mineralogy of the Grassy Creek and Saverton formations of Northeast Missouri was undertaken to determine whether a division is justified, as proposed by some stratigraphers, of these argillaceous beds into two formations. The formations were sampled systematically at surface exposures on the northeast limb of the Lincoln Arch in the vicinity of Hannibal and Louisiana, Missouri. The samples were investigated mineralogically in the laboratory. Previous studies showed that the fossils of the Grassy Creek and Saverton beds were virtually identical. The present study demonstrates that the Grassy Creek and Saverton beds are too near alike in …

Corrosion Products Of Titanium In Fused Salt Baths, Kai-Chai Chiou

Masters Theses

"Titanium is gaining great interest in the modern metal industry because of its natural abundance and its desirable physical and chemical properties. Among them, its excellent corrosion resistance, such as the resistance to normal atmosphere attack, humid and saline atmosphere attack, sea water attack, and nitric acid attack, is the most prominent characteristic being welcomed by the engineers. The usefulness of titanium would be greatly increased if it were possible to plate titanium on other metals, thus increasing the corrosion resistance of these other metals.

Much concern, at present, has been given to the possibilities of the electrodeposition of titanium …

The Use Of A Steady State Flow Reactor In The Study Of Rapid Gas Phase Reactions, Ormond Kennedy Lay

Masters Theses

"The demonstration of the feasibility of rocket propelled devices for various purposes within the past few years has initiated an intensive search for suitable reactants for use as rocket fuels. Consequently, the investigation of the properties of chemical reactions which rapidly liberate large quantities of energy has assumed major importance. In order that such reactions may be adapted to practical use as rocket propellants knowledge of the characteristics of these reactions is required. Properties such as+ the mechanism of the reaction, the speed of the reaction under varied conditions of temperature, pressure and concentrations, the conditions required for the initiation …

Horizontal Pressures On Retaining Walls Due To Line Surface Loads, John B. Heagler

Masters Theses

"Among the oldest types of structures with which engineers have had to deal are those which serve to laterally restrain masses of earth, or to prevent earth embankments from assuming their natural angle of repose. This is necessary where space is limited or the natural slope would encroach upon other property. These structures, usually called retaining walls, are subjected to forces, both lateral and vertical due to the pressures exerted by the backfill material and any loads imposed on the backfill material. The first step in the design of the retaining wall is to determine the magnitude, position, and line …

Testing Of Missouri Shales For Light Weight Aggregate Production, Jerry D. Plunkett

Masters Theses

"The original objective of this investigation was to determine by testing those clays, shales, and loesses occuring in Missouri in large deposits (over 15 feet in thickness with little overburden), which would be suitable for the production of light weight aggregate. The second objective was to investigate the mechanism of bloating as related to the physical and chemical properties of the above materials, and by using these relationships cause clays which do not naturally bloat, to bloat using some addition. The use of additives would permit the economical use of material closer to the market in many instances.
