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 …

Preparation And Properties Of 3, 3’ -Disbubstituted-2, 2’ – Three-Carbon-Atom Bridged Biphenyls, Allan E. Nader

Masters Theses

Introduction

The configuration of biphenyl has been treated in numerous articles and reviews (1, 5, 6, 7, 8, 16, 22, 23). In particular the configuration of 2,2'-bridged biphenyl derivatives has obtained attention. The synthesis of an optically active 2,2'-three-carbon-atom-bridged biphenyl possessing an ultraviolet absorption maximum at 250 mμ has been reported by Iffland and Siegel (15). These properties require first, a non-planar configuration for the molecule and second, significant inter-ring conjugation as demonstrated by ultraviolet spectra.

Several 2,2'-three-atom-bridged biphenyls have been prepared by Ahmed and Hall (2, 3) in order to obtain some measure of their specific rotation. The use …

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 …

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. …

These have been intruded in the northern part of the area by a batholithic body of granitic composition, a granitic stock, a pegmatitic granite, a granitic sill-like body and different types of pegmatite dikes and sills. The youngest intrusions are a series of northeast trending basic dikes and sills. A major easterly trending transverse fault and a series …

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 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 …

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 …

A Study Of The Behavior Of Zirconium In Aqueous Solutions And The Separation Of Radioactive Zirconium By Electrodialysis, Charles William Brauer Jr.

Masters Theses

"Nuclear reactor installations designed for power production must of necessity operate at higher energy levels than their experimental precursors. As these facilities increase in number, better solutions must be found for both technical and economic problems.

The disposal of waste materials is of primary importance and will require greater effort if satisfactory disposal methods are to keep pace with the increase of waste materials, produced by the increasing number of new nuclear facilities. The radioactive materials present in this waste material may constitute a valuable by-product from these operations if suitable and economic recovery procedures are developed. If the development …

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

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 …

K₂O/Na₂O Content As A Possible Index To The Chronological Sequence Of Some Precambrian Igneous Rocks Of Missouri, Erwin Joseph Mantei

Masters Theses

"Flame photometric analyses for K₂O and Na₂O were run on 31 samples of the Precambrian igneous rocks of Missouri. Samples were collected from the field, physically prepared and dissolved by a standard method and a modified standard method of rapid silicate analyses. The K₂O, Na₂O values obtained are averages between two methods of analyses. The modified method reduces by 80% the time required to chemically digest a rock sample. The results for both methods are not significantly different. Curtin and Company Advanced Flame Photometer was used.

Results have been plotted on graphs and a chronological sequence for the named Precambrian …

Application Of Digital Computer To Magnetic Data Interpretation Using Surface Integral Method, Afif Hani Saad

Masters Theses

"A simple method is developed for the calculation of the magnetic effect due to three-dimensional bodies. The method is based on the use of surface integration instead of volume integration. Thus, any three-dimensional body can be considered as having two surfaces, upper and lower, with magnetic pole distributions. Simple equations based on potential theory have been derived for the calculation of the vertical component and total intensity due to these surface distributions of poles. The anomalous field of the body can be obtained by subtracting the effect due to one of the surfaces from that of the other.

The method …
