The Electrodeposition Of Waxes From Emulsions, Richard Nebel Mar 1946

The Electrodeposition Of Waxes From Emulsions, Richard Nebel

Bachelors’ Theses

At the beginning of the nineteenth century, electrochemistry became an established part of the science of chemistry. Volta believed in the existence of some definite relationship between chemical and electrical phenomena and his investigations led to the discovery of a means of converting chemical energy to electrical energy. His observations became the foundation upon which all modern electrochemistry is based. Volta alternated zinc and silver disks with paper soaked in salt water between each disk. This afforded a source of electrical energy which produced a current and became to be known as the Voltaic-pile.


Permability And Porosity Of Devonian Dolomites In Northwestern Montana, Jack W. Nordquist Jun 1945

Permability And Porosity Of Devonian Dolomites In Northwestern Montana, Jack W. Nordquist

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to record data per­taining to porosity and permeability derived from physical tests performed on Devonian dolomites occurring in northwestern Montana, and to subsequently summarize the results obtained as an aid in determining the possibility of those dolomites being suitable reservoir rocks for oil and gas accumulation.

The Influence Of Heat On Some Properties Of Triethanolamine Soaps, Hetty Ricker Feb 1945

The Influence Of Heat On Some Properties Of Triethanolamine Soaps, Hetty Ricker

Bachelors’ Theses

In modern times the field of chemistry has a broad scope and even a broader horizon. Yet for a girl the field is limited. One of the few industries in which she is capable and has a slight advantage is that of the cosmetic industry. In this field chemistry is used in the manufacture of lipsticks, shampoos, oils and creams. Research to improve these items is continually going on with a hope of finding cheaper and better products than those compounds already in use.


Comparison Of Census Methods For Pheasants In Nebraska, H. Elliot Mcclure Jan 1945

Comparison Of Census Methods For Pheasants In Nebraska, H. Elliot Mcclure

Nebraska Game and Parks Commission: Staff Research Publications

In plans for the Nebraska Upland Game Bird Pittman Robinson Project the censusing of pheasants and tabulation of population densities was of prime importance. A summary of the data at hand and a comparison of the various methods tried will be discussed here.


Occupational Chemical Hazards In Industries Of Louisville And Jefferson County., Morgan Brown Lewman Jan 1945

Occupational Chemical Hazards In Industries Of Louisville And Jefferson County., Morgan Brown Lewman

Electronic Theses and Dissertations

The facts and conclusions presented in the following pages are the results of figures gathered during two and one half years of work as an Industrial Hygiene Engineer for the Louisville and Jefferson County Health Department. The factual information was acquired from many sources including extensive reading to which reference is made of the more recent publications in the bibliography and also from correspondence and discussions with authorities in various fields. Much data was gained from "in-service training" received at the United States Public Health Service; Bureau of Industrial Hygiene, Bethesda, Maryland; University of Michigan; National Conference of Governmental Industrial …


The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie Oct 1944

The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie

Bachelors Theses and Reports, 1928 - 1970

A determination of the solubility of zinc ethyl xanthate was attempted by measuring the refractive index of a saturated solution of that salt. The small increment in refractive index effected by adding zinc ethyl xanthate to water in saturation quantities rendered measurements difficult and of dubious accuracy.


Hydrogen Overvoltage Of Cadmium Bismuth And Antimony Bismuth Alloys, Edwin W. Stevens Oct 1944

Hydrogen Overvoltage Of Cadmium Bismuth And Antimony Bismuth Alloys, Edwin W. Stevens

Bachelors Theses and Reports, 1928 - 1970

A method to measure hydrogen overvoltage was devel­oped and checked with metals of known overvoltage. Alloys of bismuth and antimony and of bismuth and cad­mium were prepared and their overvoltages determined.

The Incompatibility Of Certain Alcohol And Soap Frothers, John Thomas Doherty Feb 1944

The Incompatibility Of Certain Alcohol And Soap Frothers, John Thomas Doherty

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to elucidate this phenomena of frother incompatibility, and to offer an explanation based upon several divergent lines of investigation. The research was limited to four common frothing agents, namely, pine oil, n-amyl alcohol, sodium oleate, and sodium lauryl sulphate (Dreft).

Bachelors Theses and Reports, 1928 - 1970

This thesis is concerned primarily with the production of metal powder compacts of iron and tin. In producing these compacts, the effects of process­ing variables on some of the essential properties of the pellets made were investigated.


Age Hardening Of Copper Antimony Alloys, William R. Stern Feb 1944

Age Hardening Of Copper Antimony Alloys, William R. Stern

Bachelors Theses and Reports, 1928 - 1970

A large number of alloys of varying percentages of copper and antimony were prepared. These alloys were treated in various ways which might be expected to produce age hardening. The effect of cold working was studied in the range where the alloys were malleable.

Censusing Pheasants By Detonations, H. Elliot Mcclure Jan 1944

Censusing Pheasants By Detonations, H. Elliot Mcclure

Nebraska Game and Parks Commission: Staff Research Publications

A study of the ecology and management of the ring-necked pheasant (Phasianus c. torquatus) was begun in Nebraska in the spring of 1941. Prime among the objectives of the survey was to devise some method by which the populations could be estimated or counted. In conjunction with roadside counts as practiced in Minnesota, Iowa, Ohio, Pennsylvania and other states, attempts were made to derive a closer estimate than by that method. Every game technician working with roadside counts of pheasants realizes the difficulties involved. Having had success in estimating the numbers of mourning doves by counting their calls …
