The Preparation Of Calcium And Barium Gluconate, Ronald Anthony Plzak

Bachelors’ Theses

The privilege of working on this subject is one which the author has sincerely appreciated, as it has given him the opportunity of incorporating many of the more recent contributions along the line of oxidizing aldose sugars. In reviewing these contributions, he has abstained from conveying an impression of finality and has attempted to show the many possibilities which the free sugar acids offer for the future. The experience of the last few years has proved that even long-cherished conceptions and apparently well-established facts may at any time undergo drastic revision. For this reason, the author has referred directly to …

A Comparison Of The Caffeine Content Of Various Coffees, Emil J. Petrusek

Bachelors’ Theses

Coffee must be rated as one of the most important commodities in the commercial world due to the statistics or output and consumption. There are various brands and kinds of coffee produced by the different growers and roasters. Now to sell the brands, the various concerns base their advertising upon the flavor and price of the coffee. It is a fact that the flavor of coffee is in some way affected by the caffeine present. One popular brand is advertised as decaffeinated, that is, the caffeine has been removed. Confronted with these facts, it occurred to the author to test …

A Contribution To The Preparation Of Synthetic Rubber From Butyl Alcohol, Rosalia Aloisia Leutgoeb

Bachelors’ Theses

Rubber, on account of its almost universal usefulness is one of the important materials of modern time. The unequalled utility of it is found in its physical properties, such as elasticity and toughness, which are not possessed by other plastic substances.

Groups Of Order Eight, Ludwig Eugene Loos

Bachelors’ Theses

The problem of this thesis is to show that there can be only five groups of order eight. Its basis is Kronecker's Theorem, and it demonstrates that, regardless of the number of generators used in composing the groups, the result will always be limited to four groups of order eight. The fifth and last group is a cyclic group formed on eight letters.

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour

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

In Bulletin 25, entitled The Musk-oxen of Nebraska, the writer figured and briefly catalogued the ovibovines of this State as known at that date. In the meantime an interesting new form unlike that of any species falling within our experience presents itself from the Pleistocene of Cherry County, Nebraska. The new specimen cannot be assigned a place in any of the four following genera: Preptoceras, Euceratherium, Ovibos, or Bootherium, but may possibly be referable to the genus Symbos, to which we are assigning it provisionally. It is so unlike Symbos, however, that it may be a distinct genus. …

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz

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

The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …

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.

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.

A Study Of The Deposition Of Wax In A Wax Emulsion By Electricity, Howard Mcdonald

Bachelors’ Theses

The basis of this thesis resides in an experiment performed by Dr. J.R. Koch of Marquette University during the summer of 1931.

A few days later he noticed the wax bad separated from the emulsion and had passed to the positive electrode leaving the solution surrounding the negative electrode clear.

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. …

Determination Of The Adsorptive Power Of Charcoal For Caffein In Coffee Infusions, James G. Lappa

Bachelors’ Theses

In recent years, the American public has been confronted with considerable advertising on the part of the large coffee merchants with regard to the reputed harmful effects of the caffein contained in coffee. The attitude taken against this constituent of coffee, was of course, determined by the form of coffee sold by the respective merchants, those handling the ordinary form stressing the importance of correct brewing in preventing any nervous disorders or loss of sleep, and those selling the decaffeinized brand blaming the caffein as the cause. There is considerable disagreement between authorities on this question,since most knowledge of the …
