The Aurora Borealis, Magdalen Kramschuster

Bachelors’ Theses

The Indians wondered if their beloved aurora would return. They watched and philosophized about the dawn, the twilight, the stars and all the phenomena of the heavens. They pondered the mysteries of lightening and thunder. Peoples down through the ages have written poetry about the mighty thunderhead and the lacy cirrus clouds. One by one these mysteries have been solved, but one still remains--the Aurora Polaris. Advances have been made in scientific fields so that we no longer worry whether or not the next day will come. Thunder, to us, is not the voice of an angry god. Rapid strides …

The Study Of The Curves Of Equations Having The Type Form Of Y=XN, Frank Kohn

Bachelors’ Theses

The purpose of this thesis is to investigate those properties of curves having the general type form of y = xⁿ that will enable us to determine the graph of a particular curve of this type. The investigations will not only determine the graph as it appears in the finite region of the curve but its appearance in infinite regions as well.

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.¹ Other work has been done by Mansfield² in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.³

Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making …

Applications Of Infinite Products, Lillian Schnell

Bachelors’ Theses

Jacob Nicolaus Bernoulli (1654-1705) wrote a work on "Ars Conjectandi." It was published eight years after his death. The work consists of four parts. The second part is on permutations and combinations, which Bernoulli used in a proof of the binomial theorem for the case of positive integral exponents. The book contains a formula for the sum of the rth powers of the first n integers. This involves the famous Bernouillian numbers. Bernouilli boasted that by means of his formula he could calculate "Intra semi-quadrantem Horae" the sum of the 10th power: the first thousand integers.

Experimental And Observational Geometry, Albert D. Field

University of the Pacific Theses and Dissertations

Geometry has the distinction of being one of the oldest subjects given in the high-school.

Its subject-matter was formulated and organized by the Greeks into a fine system of thought before the time of Christ. Since leaving the hands of the Greeks, geometry has received only a few minor changes, and these largely in recent years.

Heretofore, the study of geometry has been made almost entirely dependent upon memory and reasoning. Geometricians have been slow in adopting the laboratory and observational methods.

This thesis has been written to encourage the student in his work of observing geometrical forms, and in …

The Preparation Of Certain Inorganic And Organic Compounds Which May Be Of Use In Mineralogical Separations, Clarence Jay Black

Masters Theses

"In the work with minerals, there has been many mechanical means devised whereby the ores could be separated from the gangue and other material. Among those means which are used to-day, especially in the laboratory tests upon minerals, to quickly determine the value of an ore, heavy liquids have become quite popular. This means of mechanical separation is merely to place finely ground ore containing particles of varying density into a liquid of heavier density than the greater portion of the mineral, which will allow the heavier portions to sink and the lighter to float, which is usually gangue. This …

Heavy Minerals In The Roubidoux And Other Sandstones Of The Ozark Region (Mo.), Cletus Daniel Cordry

Masters Theses

"In this study an attempt has been made to determine the usefulness of heavy minerals for correlation of formations over a limited area, in the heart of the Ozark uplift in southeast Missouri. The Roubidoux formation, already definitely correlated by other means, has been rather systematically sampled throughout the area, and the heavy minerals determined to ascertain their dependability for correlation purposes. Several samples from other horizons have been studied for comparison with the Roubidoux. Also, within the area studied there are numerous isolated patches of sandstone, the horizons of which have not been definitely determined. Samples from a few …

A Means Of Making A Segregate Preparatory To Chemical Analysis Of The Sulphide Minerals In A Low-Grade Dolomitic Ore-Pulp Containing Lead, Zinc, And Copper, Julius Bruce Clemmer

Masters Theses

"The object of this investigation was to find a means of obtaining from a low-grade dolomitic ore pulp a segregate of the sulphide minerals of lead, zinc, and copper preliminary to chemical analysis so that the chemist's error of 0.03 per cent would be divided by the ratio of the segregate to the entire pulp, and hence be reduced. Two methods of obtaining the segregate were investigated: (1) By float-and-sink tests, and (2) by selective dissolution of the dolomite, which is the main gangue constituent of the ore"--Object of Investigation, page 3.

Concentration Of Fluorspar Ores In The Illinois-Kentucky District, Omar Watson Greeman

Masters Theses

"The object of this investigation is to study the means of beneficiating fluorspar ores in order that a marketable product may be made"--Preface, page v.

Color., Bruce B. Vance

Electronic Theses and Dissertations

Color, any attempt to apply the scientific principles of color vision in the making of a picture must surely fail if it be not granted at the out set that it is only to a limited degree that those principles can apply. Color appreciation is as much a psychical as a physiological, and indeed, it is psychical not only with regard to the objective impression itself, but also with regard to the subjective, the associational mental process. Previous knowledge and training, experience traditions, the association of color impressions with impressions previously received through other senses and stored away as memories, …

A Method Of Measuring The Velocity Of Gravitation, Percy Martin Roope

Historical Dissertations & Theses

For many years the velocity of gravitation, or more properly, the velocity of propagation of gravitational potential, has been the subject of much theoretical discussion. The magnitude of this velocity according to proposed theories varies from the velocity of light to infinity. According to the theory of relativity, the velocity of gravitation should be equal to that of light, and the success which experimental tests of the theory have met justify this assumption. No previous work has been done, however, which would form the basis of a direct measurement. During the past three years, experiments relating to the velocity of …

A Study Of The Ph Of Sodium Citrate In Relation To Blood Transfusion, Roman Edward Galasinski

Bachelors’ Theses

Blood transfusion, within recent years, has become a subject of paramount therapeutic importance. A few years back the technique of blood transfusion was so difficult that there were only a relatively few who possessed the requisite skill to perform the operation and then not always successfully. But since the year 1907 the evolution and perfection of blood transfusion procedures has been so steady and immense that, as a therapeutic measure, it has come into general use in the treatment of various acute and chronic lesions.

Irrational Numbers, Paul O. Smith

Bachelors’ Theses

By an irrational number is meant a number which cannot be expressed by an Integer or by a fraction. The definition in itself is rather vague and to many would not mean very much but by a definite geometric example the idea of just what an irrational number is can be much more clearly shown. Suppose we are given a line of a definite length of two inches. It can easily be seen how this line can be divided into a great number of smaller parts which can be expressed by integers and fractions.

History And Proof Of The Binomial Theorem, Ethel B. Ray

Bachelors’ Theses

Everyone realizes what a wonderful place the world really is. Yet, we of this day little think of the many generations that have gone to make our universe as it is. We think we have done wonders. We pride ourselves on our modern way. There is a tendency in man to "pat himself on the back" and boast of how well he has done. Little do we realize that millions and millions of people have given their whole lives so that we might be as we are. Of course the soldier gives his life for his country; but what of …

Methods Of Tracing Curves, Stephen Lewandowski

Bachelors’ Theses

There are two kinds of equations, algebraic equations and transcendental equations. An algebraic equation is one that involves a finite number of ordinary operations of algebra i.e. addition, multiplication, subtraction, division, extraction of roots, and raising to powers denoted by constant exponents.

Hyperbolic Functions, Margaret S. Johnston

Bachelors’ Theses

A Study of hyperbolic functions is both interesting and fruitful because of their important and historical relation to the more elementary branches of Mathematics: Trigonometry, Analytical Geometry and Differential and Integral Calculus. Historically the development of hyperbolic functions has been closely associated with the development of the properties of the circle, ellipse, and hyperbola; the earliest knowledge of the functions rising out of a comparative study of these curves, and resting on more analogy rather than clear definition and proof.

The Effect Of Aldehydes On The Solutions Of Iron Wire In Hydrochloric Acid, Mary Margaret Bannen

Bachelors’ Theses

The destruction of iron by corrosion, under the influence of natural agencies, is far more rapid than the decay of wood and other materials of construction. Were it not for iron, the erection of large works of engineering would be impossible. Their very size and consequent cost represent a large sum of human energy. This is, after all, the only true foundation for wealth and it becomes a duty to preserve iron from decay.

Indeterminate Coefficients, Armond William Bear

Bachelors’ Theses

The Picric Acid Method Of Sugar Determinations As Applied To Solutions Containing Maltose And Lactose, John J. Hennecke

Bachelors’ Theses

Lewis and Benedict based their method of sugar determination upon the reaction which takes place when a glucose solution is heated with a few C.C. of picric acid to which a small amount of alkali has been added.

The Effect Of Various Waxes On The Rate Of Evaporation Of Light Naphtha, Juel Osmund Severson

Bachelors’ Theses

Solids dissolved in a liquid produce a general decrease in the evaporation rate of the solvent. Experiments were performed, using light naphtha as the solvent and Paraffin, Japan, Carnauba, Candelilla, Ozokerite, Montan, and Bees waxes as solutes. These waxes were selected since they are the waxes most commonly used in the manufacture of floor waxes and work of the kind presented in this thesis finds its greatest application in connection with that industry.

The Catalytic Action Of Neutral Salts : The Effect Of Normal Alkali Sulphates On Alkali Acid Sulphates In The Ketonic Splitting Of Ethyl Acetoacetate, Elbridge Alvah Goodhue

Masters Theses

"The catalytic effect of neutral salts has been investigated for numerous reactions and various theories propounded to account for their action. In this work the action of normal potassium and sodium sulphates on solutions of the corresponding acid salt has been investigated for two concentrations of the latter at three different temperatures. An attempt has been made to account for the observed actions"--Introduction, page 1.

Development Of Selected Mathematical Instruments Representing Angular, Logarithmic And Arithmetic Computation, Lillian L. Troxell

University of the Pacific Theses and Dissertations

The Sextant in its earliest known form consisted of divided circles and compasses with simply sights. An early Creek astronomer of the second century after Christ, Claudius Ptolemaeus, or more commonly called Ptolemy, wrote a book entitled Megale Syntaxis tes Astron- omias, also known by the Arabic title Almagest. The instrument described in this book was called the Astrolable and was used to measure the angular distance between stars. It was made of two concentric vertical circles, the largest and outer circle was about sixteen inches in diameter with graduated arc; the central ring was movable and carried the two …

The Solubility Of Solid Paraffin In The Lower Molecular Weight Hydrocarbons, Paul Weber

Masters Theses

"In the process of oil refining, a certain fraction of distillate from the crude oil composes the so-called wax distillate fraction from which is obtained the various lubricating oils. But the presence of the waxes and solid paraffins in these oils is very undesirable as they possess no lubricating qualities. Consequently, they must be removed from this wax distillate before the oil can be marketed"--Introduction, page 1.

A Study Of Melting Points Of Various Binary Mixtures Of Waxes, George John Hable

Bachelors’ Theses

Waxes, chemically speaking, are a class of esters which consist of mono- or di-hidric alcohols united with the higher fatty acids. These waxes contain free fatty acids, free alcohols and hydrocarbons. A considerable quantity of free cerotic acid (C26H52O2) myricyl palmitate (C16H31O2. C31H63), and high melting point hydrocarbons are found in beeswax. The acids that occur in waxes appear to have an even number of carbon atoms. Paraffine, ceresine, and ozokerite are really not waxes at all according to the chemical conception. The latter two are esters of glycerine united with higher fatty acids.

Summable Types Of Series, Dorothea Maria Baumann

Bachelors’ Theses

By an infinite series we mean a polynomial, or a sequence of terms, each of which derives from its predecessor according to a fixed formula or process; there is a one to one correspondence, consequently between the terms of the series and the set of positive integers 1,2,----,n,----. Summation means the finding of a finite expression equivalent numerically to the given series; known functions only may occur, connected by a fixed number of steps; such a closed expression is called the "sum" of the series.

The Evaporation Of Pyroxylin Solvents And Non-Solvents And The Effect Of Dissolved Pyroxylin On Various Types Of Evaporation Curves, Herbert Heinrich

Bachelors’ Theses

In 1833 Braconnot described a body which he called Xyloidine. This material was obtained by the action of nitric acid on starch. In 1838 Pelonze produced a similar body by treating paper with nitric acid. Although these experiments were conducted several years before those of Soh8nbein, yet we give Schonbein the honor of priority because of bis extensive studies on the new compound "ex­plosive cotton wool". The material was produced by the combined action of nitric and sulphuric acids on cellulose. A patent was granted to him in the United States December 5, 1846, but little attention was paid to …

A Study Of The Preparation And Properties Of Some Metallic Soaps, Charley George Hagan

Bachelors’ Theses

Soap may be defined as the sodium or potassium salt of the acids that are found in fats. The metallic soaps are those soaps or salts of the metallic bases other than sodium or potassium. The Study of the preparation, properties and uses of metallic soaps is rather an old one, most of the research along that line being done during the last quartile of the nineteenth century. Nothing of any importance has been done of late years in this field of research. Nearly all the work has been done by foreign investigators. The metallic soaps of oleic acid are …

A Specific Gravity Study Of Some Of The Southeast Missouri Lead Ores And Tailings, Robert Gibson O'Meara

Masters Theses

"The object of this investigation was to study some of the Southeast Missouri lead ores and tailings to trace the freeing of galena through all of the screen sizes. It was also desired to determine the efficiency of recovery with the present treatment and, whether or not a change to finer crushing would be advisable. In order to isolate parts of different specific gravity in the ores and tailings, heavy liquids were used"--Object of Investigation, page 2.

Comparative Value Of Various Grog Materials For The Manufacture Of Zinc Retorts, Wei-Tung T. Hu

Masters Theses

"As before stated, this present investigation, of which this thesis covers only a part, undertakes to study the comparative values of various grog materials for the manufacture of zinc retorts, having as its object to find better grog materials for the purpose than those commonly in use at the present time, and to determine the best proportions of bond clay to use with each kind of grog"--Scope of Investigation, page 4.

The Separation Of Inorganic Salts From Food Products By Dialysis, Nicholas H. Tasto

Bachelors’ Theses

The phenomena of the separation of substances by 'Various membranes was first -discovered by Thomas Graham, who found that certain materials passed through membranes much more readily than others. This consequently afforded him a norm by which he distinguished a variety of substances. Those which passed through the membrane most readily he called crystalloids, because of their crystalline nature. Those which were retained colloids, because of their gelatinous or glue like consistency. The distinguishing factor is however not a legitimate one, because it has been proven by Dr. Kahlenberg that opposite reactions occur.
