Stereoradiography As Applied To Problems Of Petrology., Martin Goldstone

Masters Theses

"Stereoscopic examination of radiographs of rock and ore samples allows a rapid, cursory determination of texture and structure without time consuming preparation and use of thin sections. In addition, volumetric estimates of known mineral components can be made providing they possess significantly different x-ray absorption characteristics.

Stereoscopic effect was most pronounced for specimens having well defined components of structure such as bedding, banding, lineation, inclusions, textural variations and moderate to large x-ray absorption differences. In general, these conditions were best met by ores or ore minerals with their related gangue minerals.

Stereoscopic examination was not successful in revealing twinning or …

Fossil And Recent Beryciform Otoliths: An Adjunct To Ichthyological Classification., C. Kurt. Lamber

Masters Theses

"Otoliths are calcareous bodies, of consistent form, secreted in the auditory labyrinths of some higher fishes. Of three pairs, only the taxonomically important earstones (sagittae) are considered here. Specifically, this study is restricted to the sagittae of beryciform fishes (Order Beryciformes). Removal of some taxa from the order, and the possible relating of others, is suggested.

The morphology of beryciform sagittae is described, and three basic supra-familial groups are recognized. Diagnostic characters for families are given, with diagnoses of genera added. Sagittae of characteristic species are illustrated.

Otoliths of fossil beryciform fishes, as known from specimens and published illustrations, are …

Hydrogeology Of Reservoir Sites In The Meramec River Basin, Missouri., John H. Anderson

Masters Theses

"Governmental and private agencies have proposed construction of multiple purpose dams in the Meramec River Basin for flood control, conservation, recreation and possible power development. Evaluation of the effects of reservoirs created by these dams on ground water conditions has not been published. Study of possible effects led to the thesis that prediction of changes in ground water conditions could be made.

Several limited applications of ground water geology techniques to the problem of reservoir-ground water relations were studied; no thorough previous studies were found. Apparently, complete studies have not been undertaken by even the larger agencies.

Inspection of the …

Geology Of The Northern Half Of The Ellington Quadrangle Missouri., Robert Charles. Thornton

Masters Theses

"Geologic mapping has been completed for the northern half of the Ellington Quadrangle, Missouri. Rocks exposed in the thesis area are Precambrian and Paleozoic in age. The Precambrian rocks are granites and felsite. The Paleozoic rocks include the Potosi and Eminence Formations, of Upper Cambrian age, and the Gasconade Formation of Ordovician age. Distinction between the Potosi and Eminence Formations is difficult because of conformable and transitional relationships. In the thesis area sufficient evidence was available to separate the dolomites of the Potosi and Eminence as mappable units. This mapping should be useful as a basis for more detailed geologic …

The Application Of Quantum-Mechanical Concepts To Biological Systems, Andrew A. Cochran

Masters Theses

"The relation between quantum-mechanical concepts and biological systems is explored by studying the relation of both to the concepts of heat capacity and entropy. It is shown that the most important substances in living matter have extremely low heat capacities and entropies at ordinary temperatures. A critical analysis of the two types of quantum-mechanical interactions between particles and the interactions occurring in low-entropy systems shows that the wave properties of matter are strongly predominant in the chemical elements that constitute 99 percent of living matter. It is concluded that the wave aspects of matter are strongly predominant in biological systems. …

Mathematical Techniques In The Solution Of Boundary Value Problems., Vincent Paul Pusateri

Masters Theses

"This study was undertaken to present a summary of mathematical techniques as applied to the solution of boundary value problems in partial differential equations.

The techniques that were presented can be considered to be some of the most popular in applied science.

The salient features of the study are that different techniques can present different analytical expressions for a solution to the same boundary value problem, and from the viewpoint of computation and accuracy one solution may prove more desirable than the other.

The study also indicates that in boundary conditions where finite discontinuities exists, a slight perturbation to remove …

Permeation Of Water Vapor Through Linear Polymer Films, Mohammed S. Rifai

Masters Theses

"Film formation from thermoplastic resin solutions Is Influenced by secondary intermolecular forces. Consider what may happen when organic coatings change from a liquid to a solid state. In the liquid state it is logical to consider the linear polymer molecules as agglomerates being dispersed in the volatile component rather than being present In solution. These molecular agglomerates are referred to as micelles. They have various degrees of orientation depending on the extent and the location of dipole forces in both polymer and solvent molecules.

When a coating is applied the solvent starts to evaporate and the micelles are driven closer …

A Study Of Methods For Determining Confidence Intervals For The Mean Of A Normal Distribution With Unknown Varience By Comparison Of Average Lengths, Karl Richard Kneile

Masters Theses

“The purpose of this thesis is to briefly review various properties which may be desirable for a system of confidence intervals; and to empirically determine whether the system of confidence intervals obtained from the Student’s t distribution will produce shorter average lengths than those obtained by other methods which may be used. It was concluded from the results of an empirical investigation that there was no significant difference between the average lengths of confidence intervals obtained from a family of distributions of which the Student’s t is a member"--Abstract, page ii.

The Diagenetic Origin Of The Dolomites, Chert, And Pyrite In The Jefferson City Formation., Erik Hans Schot

Masters Theses

"Diagenesis designates all modifications which a sediment undergoes during and following deposition and prior to complete lithification, metamorphism, deep burial, and orogenesis.

Probably the dolomites of the Jefferson City Formation resulted from alteration at, or below the sea floor or the depositional interface and during diagenesis. Diagenetic dolomitization or penecontemporaneous alteration presumably involves a reaction between the calcium carbonate sediments at/or below the sea floor or the depositional interface and magnesium salts in solution or suspension in the basal layer of contacting sea water, or in the initial pr connate water trapped in the sediment.

The cherts of the Jefferson …

Petrographic analysis of forty-four thin sections and the detailed megascopic study of the samples revealed the different types of limestone rocks which were classified on the basis of Folk's (1959) Carbonate Classification. As to the environments of deposition of the Plattin Limestone determined by petrographic study, it has been concluded that this environment was one of low to medium agitation and low to medium organic activity.

Chemical analysis of the Plattin Limestone samples revealed the presence of the …

The Reaction Of Sodium Iodide In Acetone With Halogenated Epoxides -- A Mechanism Study, Thomas E. Breuer

Masters Theses

"l-bromo-2,3-epoxybutane reacted with sodium iodide in acetone to give 3-iodo-l,2-epoxybutane in 70.1 per cent yield. 3-bromo-l,2-epoxybutane produced l-iodo-2,3-epoxybutane in 69.9 per cent yield when it was allowed to react with a solution of sodium iodide in acetone. No other product could be isolated after either reaction, although it is possible that another compound may have been produced in very small amounts. The iodoepoxides were oxidized to the corresponding α-iodoacid in approximately ninety per cent yield by silver oxide"--Summary, page 40.

Investigation Of Measures Of Ill-Conditioning, Thomas D. Calton

Masters Theses

“The object of investigation in this study is that of ill-conditioning in the solution of a system of linear equations. Ill-conditioning arises when the solution is very sensitive to small changes in the coefficients of the unknowns.

A study is made in this paper of the various proposed measures of ill-conditioning for the purpose of finding the most practical method or measure for determining whether a system is ill-conditioned.

The problem of near-singular or ill-conditioned systems is of great importance in the solution of linear systems because of the extensive use made of them in practical situations. Solution of a …

The Measurement Of The Life-Time Of The 62P3/2 State Of Thallium, Danny Hale Sokolowski

Masters Theses

The measurement of the lifetime of the metastable 6²P_3/2 state of thallium is discussed. Time-sampling equipment techniques and instantaneous methods of display on an oscilloscope for measuring the lifetime are explained. The lifetime is measured as a function of mercury vapor pressure. The decay of the 5350 A thallium line is also measured to give an indication of the effect of the imprisonment of the 3776 A resonance line. This decay of the 5350 A line is also in a mercury atmosphere"--Abstract, page ii.

An Investigation Of The Acceleration Of Neutrons, Charles Edward Byvik

Masters Theses

"The acceleration of neutrons via their magnetic dipole moment in an axially symmetric magnetic field is considered. Conditions for bunching are derived and expressions for the off-axis forces are developed. It was found that neutrons off axis are forced back onto the axis and that neutrons slightly depolarized remain in their initial state. A calculation of the acceleration is made using the field of a current loop and the conclusion is that under present laboratory capabilities a neutron accelerator is not feasible"--Abstract, page ii.

An Investigation Of Drift-Covered Environments Using The Shallow Reflection Seismic Method, Kalamazoo County, Michigan, Thomas Patrick Luby

Masters Theses

Seismic work utilizing a six-channel analog seismograph and a hammer impact source successfully obtained coherent reflection events from horizon within the glacial overburden, from the drift-paleozoic interface, and from Paleozoic bedrock targets. Fieldwork was conducted in eight drift-covered environments where the drift thickness varied from 80 feet to greater than 500 feet. Factors that exerted a major control over the seismic response at each environment studied include the depth of the water table, the type of surface material underlying the shot point and geophone spread, and the use of single versus multiple geophones per channel. Each of these factors influenced …

The Correlation Of Spectra And Steric Effects In Alkyl And Aryl Hydrazones, Dennis J. Weber

Masters Theses

Introduction

The correlation of spectra, especially ultraviolet spectra, of hydrazones with their structure has resulted in considerable confusion because of the variations in spectra obtained from apparently the same basic chromophore.

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 …

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.
