The Aurora Borealis, Magdalen Kramschuster
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
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.

Heavy Minerals In The Roubidoux And Other Sandstones Of The Ozark Region (Mo.), Cletus Daniel Cordry
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
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.
The Preparation Of Certain Inorganic And Organic Compounds Which May Be Of Use In Mineralogical Separations, Clarence Jay Black
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 …

Experimental And Observational Geometry, Albert D. Field
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 …

Color., Bruce B. Vance
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
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
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
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.
