It is surprising to learn that so large a variety of igneous rocks is present in the Jardine and Crevasse Mountain mining districts, a region that is generally thought of as consisting principally of schists.

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 …

Asymptotic Series, Bernard Martin

Master's Theses

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 …

The Lime Content Of Rocks Of The Upper Cretaceous System Of Osborne County, Kansas, Herman D. Search

Master's Theses

This report is the result of several weeks of intensive study and investigation in the field and in the laboratory. In making this study of the rocks of Osborne County, Kansas, the writer is concerned chiefly with the chemistry of the rooks rather than with their geological formation. He has not attempted to make a complete analysis of the rocks, but has limited his investigation in order to determine certain facts concerning their line content. He has attempted to determine the consistency of the percentage of lime in a given member in various parts of the county and also of …

South Moccasin Kaolin Deposit, Walter Everly

Bachelors Theses and Reports, 1928 - 1970

Kaolin has never been considered an important economic mineral in Montana. Deposits of Kaolin in this state are not described in the literature and apparently very few deposits have been found.

The Reactions Of Acid Halides With Sodium, Magnesium, Zinc And Amalgams, William H. Webb

Masters Theses

"The reactions of acid halides with metals are of interest because there seems to be a possibility of abstracting the halogens from two molecules of the halide, and thereby bringing about a coupling reaction; or the formation of an intermediate organo-metallic compound which would react with another molecule of the acid halide. The result of these reactions should be the formation of diacetyl and acetyl chloride and of dibenzoyl or benzil from benzoyl chloride. This procedure would be far better than the usual procedures for the preparation of these compounds...The results reported in the literature by different workers, on the …

Some Applications Of The Principles Of Isomorphism And Variation To The Teaching Of Geometry, Ralph Mock

Mathematics & Statistics ETDs

In summary, it should be stressed that the numerous examples of this paper are important only in so much as they illustrate the use of the devices and concepts emphasized in the study. It is our premise that plane geometry, as usually taught, does not possess the value which it might have. Certain changes in content as well as in presentation would materially improve the course. This study, then, presents suggestions for improving the ordinary course in two directions. First, by presenting logical propositions from the students' experiences which are partially isomorphic to the theorems of plane geometry, it is …

A Study On The Origin Of Banded Agate, James E. Driscoll

Bachelors Theses and Reports, 1928 - 1970

Agate in any of its varieties presents numerous problems in regard to its origin. Many types have been described and their beauty elaborated upon, but little has been written concerning their formation and the problems involved. The genesis of agate implicates an amazing complexity of physical and colloid­al chemistry, as well as, various principles of geology.

On The Viscosity Of Silicic Acid Gel Mixtures, Arthur Charles Santora

Honors Theses

The Hydrolysis Of Ethyl Orthosilicate And Preparation Of Silicic Acid Gels From It, Matthew Woodrow Wilson

Honors Theses

Ethyl orthosilicate, (C2H5O)4Si, the ester of orthosilicic acid and ethyl alcohol, is a colorless liquid boiling at 165° C. It can be hydrolyzed to produce what is known as a hydrated silica sol or a sol of condensed silicic acid and ethyl alcohol; and under suitable conditions the hydrated silica sol or condensed silicic acid sol can be made to form a gel. It was decided to study the rates of the hy­drolysis and gel formation.

We have thus two reactions to be studied: 1. Eteyl orthosilicate + water ► silicic acid or condensed silicic acid + ethyl alcohol. 2. …

Time Of Set And Ph In Silicic Acid Gels, E August Laurence

Honors Theses

The purpose of this investigation was to determine the time of set and the hydrogen ion concentration of a silicic acid gel, basic in nature. A gel prepared from a mixture of 1.2511 normal sodium silicate solution and 1.0158 normal ammonium chloride was used for this purpose. The possibility of measuring the hydrogen ion concentration by the indicator method was used with considerable success by Prasad and Halliangadi (1). Previous work on this problem at Union by Marotta (2) pointed out the uncertainty of the glass electrode method due to the effect of the silicate on the electrode. The possibility …

Underground Stratigraphy Of Montana, Virgil R. Chamberlain

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to study the subsurface stratigraphy of the state of Montana from information acquired from well logs, composite logs, and measured sections. Underground stratigraphy is important for the intelligent prospecting for oil, gas, or water. A knowledge of the strata beneath us can be gathered only by measurements of numerous outcrops or by deep drilling with careful sampling or logging of the formations passed through.

Study And Correlation Of Belt And Cambrian Arkoses Near Limespur, Montana, Ryan C. Mcnamee

Bachelors Theses and Reports, 1928 - 1970

In the vicinity of Limespur, Montana, a siding along the Northern Pacific Railroad near Whitehall, Montana, occurs a characteristic type of arkose where­ in many small red mineral grains are distributed throughout the rock mass. It is in this respect that this arkose differs from other arkoses in the surrounding region.

The Jefferson Canyon Gypsum Deposit., Arthur Talpt

Bachelors Theses and Reports, 1928 - 1970

Solution To Theory Of Equations For Teachers And Graduate Students, Arthur Lawrence Birkholz

Bachelors’ Theses

This thesis is intended primarily for teachers and graduate students who often find it necessary to review all or part of the basic theorems in the study of equations. Dickson's excellent book on the subject, "First Course in the Theory of Equations", is a recognized authority, so to facilitate a study of this book the writer has worked the problems suggested by Dickson, because these problems, more than any explanation could, illustrate and simplify the theorems on equations.

The user of this work-must bear in mind that there may be several ways of working many of the problems, and hence …

The Surface Tension Of Ethylene Glycol With Various Additions, Walter W. Eichenberger

Bachelors’ Theses

Ethylene glycol is a compound of great interest both from a practical and theoretical viewpoint. In its properties it lies midway between ethyl alcohol and glycerol. Several years ago this substance was a scientific curiosity and was produced solely by laboratory methods. At that time it had little commercial value principally because of its scar• city. However, the demand for glycol steadily rose after its many useful properties had become known until today it is a very common chemical staple. Such uses as in a non-freezing dynamite, as an anti-freeze for automobile cooling systems, as a hygrosoopic agent, as a …
