Fossil Bearing Basalts (More Particularly The Yakima Basalt Of Central Washington), George F. Beck

All Faculty Scholarship for the College of the Sciences

Such an overwhelming majority of the floral and faunal remains of the earth's crust have been yielded by rocks of sedimentary origin that generalized statements concerning the occurrence of fossils often neglect their more rare appearance in metamorphic and igneous rocks. In fact there is the temptation, after volcanic tuffs have been excluded as more or less sedimentary, to venture the positive assertion that by their very character igneous rocks are incapable of recording the presence of the life which may have existed at the time of their extrusion. As a result, most that has been written concerning fossil floras …

The Extraction Of Tantalum And Columbium From Tantalite, Stanley P. Wisniewski

Bachelors’ Theses

In the summer of 1932, the Milwaukee Public Museum, sent an expedition to the Bad Lands and Black Hills of South Dakota, under the direction of Dr. Ira Edwards, Curator of Geology in that institution. It was at this time that the author, a member of this group, while studying the pegmatites of the Black Hills, became interested in the tantalum-columbium bearing minerals of that region, namely tantalite and columbite. At that time the writer made a detailed mineralogical study of these two minerals, as well as a thorough investigation of their occurrence in that region. In the fall of …

Arrowhead Making In The Ginkgo Petrified Forest, George F. Beck

All Faculty Scholarship for the College of the Sciences

In a sense we must give the Indians credit for being the original discoverers of these fossil forests of Central Washington. Not that I have been able to run down any legends or traditions regarding fossil logs or any certainty that the Indians recognized them as trees in stone. My opinion is that they could not have failed to recognize them as trees. Be that as it may, they long ago took recognition of the fact that certain logs were to be prized as the source of flint for their arrow-heads.

The Sine-Function, Audrey Siehr

Bachelors’ Theses

Since the sine function is one of the most important elements of that phase of mathematics known as Trigonometry, it is only proper that we pause a moment for a short explanation of that subject. Trigonometry originated with the Greeks as the name itself implies. It was derived from the two Greek words trlgonon, meaning triangle; and metria, meaning measure. Trigonometry, then, dealt with problems related to measuring triangles.

Bird Studies Of The Bear River Marshes, Ernest W. Parkinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.

Wax Analysis With Special Reference To Montan, Spermaceti, And Chinese Insect Wax, Margaret M. Plonsker, Margaret E. Seippel

Bachelors’ Theses

The presentation of this thesis under joint authorship finds its justification in the fact that much of the experimental work, though performed individually, is of such a nature as to warrant a unified description. In this way the reader is afforded a better representation and clearer conception of the problem, and a substantial guide for further investigation. Though much work has been done in the field of wax analysis, little is known of the higher fatty acids and alcohols of many of the waxes. Their isolation has been infrequent, and few if any of their derivatives have been formed. It …

Steric Hindrance In The Ketonic Splitting Of Substituted Acetoacetic Ester, Claude Stanley Abshier

Masters Theses

"The phenomenon of steric hindrance has been observed and investigated in a variety of reactions, most of which have been with aromatic compounds. In this branch of study the speeds of reaction of ethyl acetoacetate, α-mono-methyl-ethyl-acetoacetate, α-mono-ethyl-ethyl-acetoacetate, α-mono-propyl-ethyl-acetoacetate in the presence of 0.05 and 0.10 normal hydrochloric acids have been investigated at temperatures between 60⁰C. and 90⁰C. An attempt has been made to explain the results obtained"--Introduction, page 1.

A Study Of The Acoustics Of Some Stockton Auditoriums And Rooms, Glen Halik

University of the Pacific Theses and Dissertations

Though the original purpose of this thesis was to investigate the cause for criticisms of the acoustical properties of the College Auditorium, it has been enlarged to a study of other Stockton Auditoriums and rooms with the idea of securing a technique of acoustical analysis similar to that of acoustical engineers in the industries. It was planned at first to set up an oscillator and reverberation meter, but it was found that the apparatus expense would be quite prohibitive. This research was therefore confined to noise meter measurements and reverberation calculations, and includes much of architectural and engineering branches. However, …

A Study Of Methods For Separating The Elements That Interfere In The Electrolytic Deposition Of Lead As Lead Oxide, John Shaw Sabine

Masters Theses

"The electrolytic determination of lead as lead dioxide is a very desirable method, due to its simplicity, accuracy, and the small amount of the analyst's time required. The electrolytic method functions when both large and small amounts of lead are present. The method depends upon the fact that from a nitric acid solution the lead is plated upon the anode as lead dioxide; from the lead dioxide deposit the percentage of lead may be calculated.

An electrolytic method, for determining the lead in samples containing from 5 to 150 mg. of lead, was described in a paper by Schrenk and …

The Preparation And Specific Gravity Of Pure Formic Acid And Its Aqueous Solutions, Leo Henry Merchie

Masters Theses

"Formic acid, the lowest member of the fatty acid series, was obtained as early as the seventeenth century by distilling ants with water. Other methods were later found after the correct constitution of the acid became known. This acid is not difficult to prepare in a water solution, but it is difficult to obtain in the anhydrous state...The purpose of this work is to study the various methods of preparing anhydrous formic acid, to improve a method for preparing the anhydrous acid, and to correct specific gravity tables for aqueous solutions of formic acid"--Introduction, page 1-2.

Problem-Solving In Arithmetic, Eva M. Acker

Bachelors’ Theses

For a century arithmetic has been a popular subject in the elementary schools, and has consumed more time than any other subject. The war had an effect in reducing this time on arithmetic, largely due to the war-time emphasis on health, food production, back-of-the-line morale, and kindred subjects. More recently, school activities and playground work have come in for a reasonable share of the school time. The Twenty-ninth Yearbook recognizes the child as the center of interest, and the final criterion of all values being the effect any technique of teaching or any content of instruction has on the child. …

The Development Of A Quantitative Scheme For The Separation Of Quaternary Mixtures Of Alkyl Halides And Alcohols, Edward Joseph Pfeifer

Bachelors’ Theses

Organic chemistry offers a large field for quantitative investigation. The nature of many organic compounds makes for difficult analysis. The separation of simple mixtures is oftentimes a problem. The work undertaken in this thesis is of special interest because it combines several phases of chemistry, in the investigation of a problem, which by its very existence, suggests the need for solution.

Thomas William Robertson, The Mid-Victorian Dramatist, James A. Fitzpatrick

Bachelors’ Theses

It is the purpose of this thesis to determine the position of Thomas William Robertson in the dramatic history of the nineteenth century, and to discover what contributions, if any, he made to the drama of this period. In addition to making a careful analysis of Robertson's more important dramas, I have read all the outstanding dramatic histories of the middle of the last century and some of its popular dramatic works. In my investigation of this problem I have explained the dramatic conditions of the early and mid-nineteenth century, revealed the characteristic tendencies of its popular plays, set forth …

The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The mounted sketleton of Eubelodon morrilli was installed in the west wall case of Elephant Hall December 31, 1931, and has attracted the attention and favorable comments of citizens and other guests. It should be explained that the case in which it is displayed is ten feet deep, sixteen feet high, and extends the length of the hall. Altogether it is a large and impressive mount which reflects credit upon its preparators, and is an important and instructive addition to the Morrill Palaeontological Collections. The pose is spirited and interesting, and the action is all that can be expected of …

Factors Affecting The Electrolytic Deposition Of Small Amounts Of Lead As Lead Dioxide And The Composition Of The Deposit, Thomas Gordon Day

Masters Theses

"The purpose of this investigation is to determine the best conditions for the quantitative deposition of lead when the content of this element is below 5 milligrams and to study the composition of the deposited PbO₂. The following conditions were studied during the course of the investigation. 1. The maximum amounts of copper and zinc permissible for the quantitative determination of lead. 2. Methods of separating lead from zinc when the latter element is present in amounts greater than are permitted in the determination of the lead. 3. The separation of lead from copper when this element is in greater …

Radio And A Public Address System For The High School, Kenneth H. Westlake

University of the Pacific Theses and Dissertations

All the findings and knowledge of electricity and magnetism are not new; even the Greeks as far back as 600 B. C. knew something about these forces. As time went on the facts increased.

After the experiments of Faraday, Maxwell, Hertz and such men as these, electricity and magnetism became a vital part of human life and endeavor. Within the last twenty-five years the advances in electricity have been very rapid. The action of the electric current is a vital part of many developments and is helping to make human life more enjoyable and interesting.

Almost all schools today are …

Probability, The Historical Development Of The Theory And Its Application To Games Of Chance, Rose M. Brandt

Bachelors’ Theses

The theory of probability had its origin in isolated mathematical problems taken from games of chance. The beginnings of many of our modern theories and concepts can be traced back to Chinese origin. So too can the theory of probability. With the exception of the Chinese problem, dating from the beginning of the Christian era, no reference seems to have again been made to the theory prior to the latter part of the fifteenth century. In 1494 an Italian monk, Pacioli, was one of the first to introduce the "Problem of Points" into a treatise on mathematics. By the solution …
