A Study Of Form And Content For A Laboratory Manual To Be Used By Students In General Chemistry Laboratory, Berne P. Broadbent

Theses and Dissertations

This investigation was carried out for general chemistry classes in which recitation and laboratory work are closely integrated and in which very close supervision is given to laboratory classes. Results indicate that there are fewer failures under these conditions if students do individual work. Students receiving grades of over 80% seem to work just as effectively in pairs as they do when working individually, but about 5% who fail when working in pairs could, apparently obtain grades above 60% if they did individual work. The formal full statement type of report is substantially more effective than the questionaire report as …

Van Slyke Determination Of Amino Acids In Beer And Malt, Rebecca Spilberg

Bachelors’ Theses

A change has been taking place in the brewing industry during the last few years. There has been a tendency to give up traditional methods of brewing for methods based on sound scientific principles. In line with this, the work of the chemical research laboratory has grown from almost nothing Until it now plays a role of vital importance to the industry.

The Determination Of Of Bromo Acid, Genevieve M. Stein

Bachelors’ Theses

The use of bromo acids in lipstick is comparatively recent. Since its use is so necessary to the modern lipstick in order to impart indelibility and staining power, the fact that bromo acid arouses a toxicity in the presence of castor oil in some individuals does not keep it from being one of the most important constituents of the stick. However, in order to keep the toxicity down to a minimum it is necessary to keep the type end amount of bromo acid under control. It is, therefore, highly important that a check on the amount of bromo acid be …

A Study Of The Reactions Of Anhydrous Hydrogen Fluoride On Organic Compounds, Daale Jones

Malonic Acid Synthesis, Mary K. Hormuth

Bachelors’ Theses

The search for new organic compounds, the discovery of their proper­ ties and the utilization of them, both in the industrial and the biological field has always been the challenge to the organic and research chemist. In particular, the study of fatty acids and their related compounds has been the particular problem to not only the physiological chemist, but also the industrial chemist. The research in this direction has tremen­dous possibilities tor only the even carbon and normal chain acids have been isolated in nature. Here difficulty is often met when trying to establish and identify this type of acid …

Dielectric Properties Of Various Organic Compounds, Joyce Elaine Eiling

Bachelors’ Theses

Condensers are widely used for many purposes. These devices are employed in one form or another in radio transmitting and allied industries such as television and amplifier circuits. They are used in automatic equipment, telephone, telegraph, and railway signal equipment as well as in condenser type motors. Condensers reduce sparking and arcing at contact relay points, switches, circuit breakers, time clocks, and thermostats. A vital part of a condenser is the dielectric. In present day condensers mineral oil is used extensively.

The purpose of this investigation is to study other organic compounds in an effort to find a good di …

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.

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

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.

Bachelors Theses and Reports, 1928 - 1970

Although powder metallurgical methods have been used for years to fabricate tungsten and platinum, very little scientific data have been recorded until the beginning of this century. A large percentage of all commercial production at present is based upon past practice rather than upon scientific knowledge.

Methods Of Determining Porosity And Spatter Losses Of Arc Welds, Campbell W. F. Funk

Bachelors Theses and Reports, 1928 - 1970

The original objective of this project was to determine the effect of varying current intensity and electrode coating composition upon the spatter losses and porosity of arc welds made by alternating current. This subject was suggested by the Welding Research Council of the Engineering Foundation, which is a clearing house for welding research in order to avoid du­plication of work.

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.

The Electrodeposition Of Iron-Manganese Alloys, Raymond D. Magorien

Bachelors Theses and Reports, 1928 - 1970

An electrodeposition of an iron-manganese alloy was made from the same conditions determined by previous re­search. Various addition agents were experimented with in an attempt to produce better conditions for electro-deposition. It was found advantageous to add small a­mounts of sodium lauryl sulfate and ammonium sulfite to the electrolyte.
