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 …

Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour

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

Of late, anthropological literature relative to the association of man and extinct mammals, especially bison and mammoth, has received many contributions from various and widely separated sources. Naturally the question has arisen whether man's advent in America is somewhat earlier than has been generally admitted, or whether certain extinct animals have persisted longer than has been realized. The issue is one of such importance and interest that even minor contributions seem desirable. It is well understood by all that the evidence, when submitted, will be properly weighed, and that conservative judges may rule out much or all of the testimony. …

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 …

The Extraction Of Waxes And Wax Mixtures By Means Of Common Organic Solvents, Bernard J. Finley

Bachelors’ Theses

This work was performed with the intention of giving some information of the solubility of the more common waxes, by means of extraction with several commercial solvents. Besides the individual waxes, various mixtures of waxes were also used to determine the effect of the mixtures on the extractability.

Determinations are also made to find the extractable matter in a commercial furniture polish and shellac. The acid, saponification and iodine values of the polish and shellac are also found.

Very little work seems to have been done on the accurate determination of percentage of extractable matter in waxes and mixtures of …

Dielectric Constant Of Absorbed Water, Reiji Funabiki

University of the Pacific Theses and Dissertations

That the dielectric constant of a substance is one of its important properties is a fact that has been very commonly taken into consideration by electrical engineers in design of apparatus and transmission lines. The importance of the dielectric constant is equally evident to the chemist working in the field of nonaqueous solutions, and Walden and others have spent a great deal of time and energy in attempting to measure the relationship of the dielectric constant of a solvent to its solvent ability, the degree of ionization of a solute dissolved in it, etc. Indeed it has become very common …

A Study Of The Effect Of Temperature Upon Reactions Between Stannous And Arsenate Ions In Silicic Acid Gels, Ellis Elder

University of the Pacific Theses and Dissertations

Chapter I: Statement of the Problem

The purpose of this investigation was to determine to what extent the reaction between stannous and arsenate ions in silicic acid gels is influenced by temperature.

This was to be done by observing (1) the rate of crystal growth; and (2) the appearance of the crystal growth in sets of gels identical in composition but kept at different temperatures throughout the process of crystal growth.

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 …

The Electret - An Effort To Find The Cause Of Its Permanent Polarization, Ernest F. Lundeen

University of the Pacific Theses and Dissertations

Certain waxes when solidified in a strong electric field exhibit unusual electrical properties. Several days after formation there is a polarization in the direction of the field which seems to persist for an indefinite length of time. The surface that was in contact with the anode during formation first ass a negative charge and then obtains a positive charge, which under proper conditions is practically permanent. The surface that was in contact with the cathode first has a positive charge and then obtains a negative charge which is the permanent charge.

A Study Of The Colloid Obtained From Weathered Lignite, Cecil O. Lohn

Theses and Dissertations

When Lignite is exposed to the action of weather it undergoes various changes, probably due to oxidation. Surface beds of lignite are often rejected by the miners as inferior coal, due to the weathered condition. But when this weathered lignite is treated with sodium hydroxide, and the resulting solution allowed to evaporate to dryness, there is left a hard, shiny substance very similar in appearance to hard coal. This dried product has been exploited under the name of Dakolite. When dispersed in water this product makes a very good wood stain.

Tests made on Dakolite show that it has colloidal …

The Influence Of A Halowax Oil On The Viscosity Of Lubricating Oil At Various Temperature, Clarence J. Riordan

Bachelors’ Theses

Halowax Oil is used as a.filler in plastic compounds, on wood as an insecticide against termites, and the Petroleum industry finds it a very good valve lubricant in internal combustion engines and a solvent for tarry residues which deposit on combustion chambers. Due to its low viscosity and very low congealing point it would therefore seem logical to investigate this further with the idea of using Halogenated oils as winter lubricants for automobile engines. The work naturally suggested further study, such as its effect on corrosion of steel, aluminum, iron and copper, the flash and fire points, viscosity at various …

Actino- And Thermo- Response Of Molybdenite In Vacuo With Various Colored Lights, John H. Fulton

Master's Theses or Doctor of Nursing Practice

The purposes of this investigation are to study the reaction of molybdenite cells to light of various colors while in vacuo and at various temperatures. The samples of molybdenite were also subjected to radiant heat in the last part of the experiment, which was undertaken to determine to some extent the amount of thermos-electric effect which was due to thermal radiation in the first part of the investigation.
