A Comparison Between Saponification And Iodine Values And Melting Point Curves For Mixtures Of Various Natural Waxes And Halowax 1012, William Kenneth Watts

Bachelors’ Theses

This thesis 1s concerned with the nature of the action of the lowering of the melting point of the various natural waxes by the addition of Halowax. The problem was suggested by the work of Louis Kroening in his thesis, "The Effect of Halowax 1012, 1013, and 1014 on the Melting Points of the Various Waxes", and also by that of Joseph M. Sevenich in his thesis, "An Investigation of Halowaxes in Trinary Wax Mixtures". The former showed conclusively that the presence of Halowax in a wax mixture invariably lowered the melting point of the natural wax. The latter showed …

The Existence Theorem Of Ordinary Differential Equations, Harris J. Dark

Master's Theses

There are a great many devices for solving differential equations of certain special forms. But there is a large number of classes of differential equations that are not included in these special forms and cannot be integrated by quadratures or other purely elementary methods. When mathematicians were forced to abandon their cherished hope of finding a method for expressing the solution of every differential equation in terms of a finite number of known functions or their integrals they turned their attention to the question of whether a differential equation in general had a solution at all, and, if so, of …

Nebraska In Relation To The Problems Of Pleistocene Stratigraphy, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

Nebraska is so peculiarly situated with respect to Pleistocene deposits of glacial, fluviatile, and eolian origin that it holds the key to the solution of many important problems of the stratigraphy of that period. A brief outline of the Pleistocene geology of Nebraska with several illustrations is followed by a statement of and brief discussion of several of these problems. The main problems touched upon are: age of the Loveland loess, Pleistocene classification, correlation with Europe, the need for a better understanding of what is meant by "glacial" and "interglacial," the problem of glacial and interglacial loess, the duration of …

Remedial Work On The Division Of Decimals, M. Thomasine Schwind

Bachelors’ Theses

The important element in remedial strategy is the reduction of the necessity for it. Prevent more, so as to have to cure less! In all learning and especially in the processes of arithmetic, our attack must be based upon a four-fold basis. Each is affected by the other three. Initial learning, maintenance, measurement and remedial work are the four components of efficiency. before remedial work can be carried out efficient testing must be done.

The Bursting Strength Of Ethylcellulose Films In Various Organic Solvents, James B. Miller

Bachelors’ Theses

Ethylcellulose, one of the newest of these derivatives, has been widely used and investigated in the last few years because or its extraordinary properties which are unavailable in any other single cellulose derivative.

Electro-Dialysis Of Gum Arabic By Means Of A Continuous Flow Apparatus, Jerome J. Kowalski

Bachelors’ Theses

This work was performed with the intention of devising a method for the electro-dialytlc separation of electrolytes and colloids which provides for the continuous flow of sol and dialysate during the process.

The facts which were instrumental in directing the author's attention to this problem are: (1) The lack of a simple and efficient apparatus for electrodialysis, and (2) the wide range of possibilities for the application of such a device.

The purpose of this thesis is the presentation of the better algebraic methods of the segregation of real roots of equations of lower orders and a brief historical sketch of the advance made in the development of algebra. Mention is also made of a few of the men who have made notable contributions to this field of mathematics and the time, as nearly as it is possible to determine it, when new ideas were discovered.

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.

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 …

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 …

Classification Of The Tertiary System In Nebraska, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

This paper represents the results of almost continuous research by the Nebraska State Geological Survey on Tertiary stratigraphy in Nebraska during a perIod of more than 10 years, with special attention to the present acceptable stratigraphic nomenclature. Cogent reasons are presented for the retention of such well-known names as White River, Arikaree, and Ogallala, all now redefined and elevated to group ranking. “Loup Fork” and “Loup River,” "Nebraska beds", and “Republican River" are considered obsolete. The application of fossil seed zones to problems of correlation is noted. The table of Tertiary Formations of Nebraska summarizes the Tertiary stratigraphy in Nebraska.

The Nebraska State Geological Survey And The "Valentine Problem", Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

The Nebraska State Geological Survey is primarily concerned with the stratigraphic classification of the Tertiary lithologic units in this state. When the stratigraphic relationships are fully understood, the faunas can be properly and correctly related and named, whether the stratigraphic names or others are used. It should be understood that this survey, in determmmg its acceptance of stratigraphic names on the basis of priority, is making every effort to differentiate names which have been applied in a strictly stratigraphic sense from names which. while they may be older, were applied in only a geographic or faunal sense and have only …

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.

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.

The Iodine Value Of Tung Oil, M. Beto Reiss

Bachelors’ Theses

In the oil and fat industry the iodine value is one of the most important criteria in testing for the purity of the substance at hand. According to the amount of iodine absorbed fats are classified as drying, semi-drying, and non-drying oils. If the respective oil possesses and iodine value lying between 130 and 200, it is considered a drying oil; between 95 and 130, a semi-drying oil, and between 1 and 95, a non-drying oil.
