Linearity In Factor Analysis, Opal Emmons

Master's Theses or Doctor of Nursing Practice

The uniqueness of mathematics in that it is a science complete in itself makes it possible to apply mathematical tools to sciences which, in themselves vary widely in content. There is, however, a particular difficulty which must be surmounted. A given mathematical procedure may be valid in the science of mathematics but invalid in another science, such as psychology. The reason for this is that sometimes there is a discrepancy between the implicit assumptions in the field of mathematics and those implicit in the field of application. The purpose of this investigation is twofold: (1) To point out that linearity …

The Age Hardening Of Silver With Copper-Silicide, Joseph Edward Shaw

Bachelors Theses and Reports, 1928 - 1970

The successful application of the phenomenon of pre­cipitation hardening to aluminum and copper has indicated the possibility of hardening all metals in the same way. The phenomenon of age hardening was discoveredin 1911, and since that time much research has been car­ried on in all parts of the world on various alloy sys­tems.

The Age Hardening Of Copper With Manganese Silicide., Gordon A. Davis

Bachelors Theses and Reports, 1928 - 1970

The increase in hardness is attributed to the manganese silicide being precipitated from solid solution and deposited between crystal planes. The subsequent softening which occurs on prolonging the period of reheating is believed to be due to an agglomeration of the dispersed hardening agent.

Geology Of The Golden Sunlight Mine And Vicinity, Roy H. Earhart

Powder Metallurgy, Cecil R. Waldron

Bachelors Theses and Reports, 1928 - 1970

The metal powders may be produced in a number of different ways. In metals where the intercrystalline material is brittle enough, they may be ground in a ball mill or eddy mill. The fineness of such a powder is more or less controlled by the grain size of the original metal.

Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That the higher valleys of the Wasatch Mountains were occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows in a rough way the extent of the glaciated areas in the Central Wasatch (11 ). In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of …

Qualitative Analysis Of Silver, Lead, Mercury, Copper, Bismuth And Cadmium By Means Of Spot Tests, Jerome S. Szymanski

Bachelors’ Theses

For years the analytical chemist avoided the use of organic chemicals in his work. Some of them he accepted as a matter of course, without paying much attention to their value. Chloroform was used as a solvent in testing for bromine and iodine. A few indicators were used, but organic chemicals were only sparingly used in analytical work. The beginning of the twentieth century marked the introduction of the use of organic dyes in analytical work. Since then, their use has grown steadily, especially during the past decade due to the work of Drs. Feigl and Pregl.

Electrolytic Preparation Of Glucuronic Acid From Glucose, Thomas Mcguine

Bachelors’ Theses

The present work was undertaken to check the results of Dr. R.A. Leutgoeb in the electrolytic preparation and also to further the separation of glucuronic acid from the electrolyte.

Because up to 1938 no efficient chemical method of glucuronic acid had been developed. Dr. Leutgoeb undertook to remedy this lack by making use of electrolysis for a preparation from alpha methyl-glucoside. Such a chemical method is needed if biochemists wish to successfully continue work on the metabolism and deoxioating functions of glucuronic acid. Biological means indeed produce glucuronic acid but in low yields and after much time and labor. Hence …

The Purification Of Linolenic Acid Of Linseed Oil Fatty Acids By Fractional Crystallization From Acetone, Sylvester Ralph Taterzynski

Bachelors’ Theses

Recently the fat and oil chemists are concerning themselves with a more thorough analysis of the fats and oils. In former years chemists in this field seemed to be satisfied with a relatively superficial analysis, used especially in detecting adulteration of oils.

This lack of detailed- analysis was, in great part, due to the fact -that there was no good methods of separation and analysis and especially of the higher unsaturated fatty acids. Only generalizations and approximate calculations were made. However, in the past few years, a decided step has been made toward a far more detailed investigation of the …

Viscosity Of Ethyl Cellulose In Various Binary Mixtures, Frank L. Tinetti

Bachelors’ Theses

Viscosity is that property of a fluid by which it resists continuous deformation, especially characteristic of thick liquids. It is also variously defined as the resistance experienced by one portion of a liquid in moving over another portion, or the "internal friction" of the liquid. This property is the reciprocal of "fluidity", which is the measure of the tendency of a liquid to flow.

A Preparation And Testing Of Bromo Acid, Joseph M. Jauquet

Bachelors’ Theses

Asymptotic Series, Bernard Martin

Master's Theses or Doctor of Nursing Practice

The purpose of this thesis is to follow the development of the asymptotic series from the beginning made by Euler, in his solution of problems, to the modern applications of asymptotic series, also to present a definition and an analysis of asymptotic series, explain some different theories of their use, and show the ways in which they find common usage. The use of asymptotic series is a comparative new development in the field of applied mathematics. The divergent series were not used as a method of calculation until Euler showed that they gave close approximations in the solution of problems. …

The Kolbe Synthesis With Alkyl Ortho-Xenols, Sidney Harris

Master's Theses

The phenol series of compounds has shown marked therapeutic activity. Generally there are two types phenols used as germicides and fungicides - (a) the very soluble type such as the resorcinols and ( b) the less soluble type such as the phenyl phenols and salicylic acid and its derivatives.

Condensation Of Olefins With P-Mercapto-Diphenyl, Raymond Michael Abrams

Master's Theses

Markownikow's rule states that in the addition to unsaturated ,negative groups add to the carbon atom having the least number of Hydrogen atoms. It has been observed that mercaptans and hydrogen sulfide add to olefine contrary to Markownikow's rule in the presence of sodium alcoholates or sulfuric acid.

The Adsorption Of Hydrogen Ion Upon Arsenic Trisulfide Hydrosols Preceding Coagulation, Myron L. Corrin

Bachelors’ Theses

Since the recognition of the colloidal state by Graham in 1861, the importance of colloidal systems in both pure and applied science has received increasing recognition. Many industrial processes are colloidal in nature; the chemistry of living matter is essentially colloidal chemistry; analytical chemistry involves the recognition and removal of matter in the colloidal state. As a result of the many applications of this branch of chemistry, the mechanisms underlying typical processes of colloidal systems are of vital significance. Specifically, the destruction of colloidal systems by electrolytes, finding as it does such wide use, is of considerable importance. In the …
