A Study Of The Decomposition Potentials Of A Commercial Gluconic Acid Bath, Roman L. Pozorski

Bachelors’ Theses

The study of electrochemistry is not only fascinating and worthwhile, but essential to the student of chemistry in the understanding of many theories and chemical phenomena. Though electrochemistry is still in its infancy, numerous substances are prepared electrolytically in industry. It is reported that about 15% of all the chemical goods manufactured are prepared by electrochemical industries. Of the various types of studies, in electrochemistry, the one which appears to be most appealing is the analysis of chemical reaction sin which electrochemical methods are used. The determination of decomposition potentials is one of these methods. A knowledge of decomposition values …

Marital And Population Composition Of Sheboygan County January 1, 1925 To December 31, 1936, Rhudolph John Ploetz

The table of contents giving the title and page of tables, is intended to be of great value to the reader, in that just a particular table wanted is designated and well-outlined. Regarding a lengthy explanation for each or any one of the tables is really …

Some Properties And Applications Of Symmetric Functions, Marie C. Kniewel

Bachelors’ Theses

The word symmetry suggests that more fundamental aspect of all being, unity. In mathematics as in all other sciences, there is no going without having glimpsed something of that unity. Given even a glimpse, the wayfarer on the path toward mathematical truth, finds the traveling made, not easy, but more certain.

The Influence Of Ph On The Activity Of Trypsin And Papain (Caroid) As Measured By A Modification Of The Northrup Gravimetric Casein Method, Frank W. Dragan

Bachelors’ Theses

Hydrogen ion concentrations have long been recognized as an essential factor in many biochemical processes.

The influence of hydrogen ion concentration upon enzyme activity has been of especial importance as proteolytic enzymes are rapidly gaining in use in various industries, principally the tanning industry.

A Comparison Of Ths Digestive Powers Of Trypsin And Papain On Casein And The Effect Of Certain Mild Antiseptics On These Powers, Joseph E. Steker

Bachelors’ Theses

The purpose of this thesis is to study the effect of certain mild antiseptics, such as Benzoic acid, Boric acid, salicylic acid, Phenol, Cresol, Thymol, on the digestive action of the enzymes Trypsin and Caroid (papain). A thorough perusal of the literature reveals only a small amount of data dealing with the influence of common antiseptics on enzyme action. Because of the important uses of enzymes in industry and the need of antiseptics for protective action, this problem is of great importance. The author wishes to acknowledge the kind cooperation of Dr. John R. Koch, Head of the Department of …

The Solution Of The Quartic Equation In One Variable, Jack W. Bril

Bachelors’ Theses

The purpose of this thesis is to discuss two of the foremost solutions of the quartic equation---Descartes' method and Ferrari's method. Most of the ideas were garnered from books on the theory of equations. The historical material was obtained from histories of mathematics.

Geology Of Some Gold Deposits Of Montana, Leo Edwin Efraimson

Bachelors Theses and Reports, 1928 - 1970

Gold is one of the rarer metals in nature, and chemically it is one of the most inactive. Gold forms stable, natural compounds with few other elements, and only with metals.

The Hyperbola, Mary Aquin Miller

Bachelors’ Theses

This thesis is by no means an exhaustive presentation of the subject "The Hyperbola" or of the many and varied properties connected with this conic section and its associated parts. The aim in writing this paper has been to give a general outline of the history of the development of the hyperbola, to show the various constructions of it, and, with this as a basis, to show the relation between the hyperbola and its connected parts.

A Short Study Of Laplace's Equation, Sidney Teweles Jr.

Bachelors’ Theses

Perhaps if I set forth my original inspiration for this thesis, the reader will be better able to understand the reason for the apparent limitations of treatment. In my study of differential equations, I had the task set before me of presenting a discussion of Laplace's equation to the class. A seemingly easy matter turned out to be quite difficult for the reason that most texts make but brief use of Laplace's equation. Thus in a mathematics book reference will be made to Laplace's equation simply as example of a mathematical process. Some of these processes are the change of …

The Minerals Of New Mexico, Lee Mcguinness

Earth and Planetary Sciences ETDs

Inorganic bodies known as minerals make up, either in whole rock-masses or in isolated form, the material of the upper crust of the earth. Through the evidence furnished by this study of meteorites, we also infer that other bodies in the universe are made up of minerals, or at least those portions of them which are represented by meteorites.

Since minerals are, then, important in making up the observable part of the earth, a study of them is importance in any study of the earth. Because the variety of minerals occurring in New Mexico is large, it will be of …

A Metallographic Study Of Primitive Copper Work., John A. Alley

Bachelors Theses and Reports, 1928 - 1970

The field of archaeology and that of metallurgy appear to be widely separated and in no way related. Work done in recent years, however, tends to show that, in many ways, the metallurgist can supplement and enhance the information gain­ed by the archaeologist, at least in regard to those objects which have been made of metal.

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.

An Investigation Into The Bromate Method Of Manganese Determination, Ray A. Bunday

Electronic Theses and Dissertations

Throughout the history of research in the science of Chemistry the problem of the quantitative determination of manganese has always been a perplexing one. The results have usually fallen short of the theoretical value and has necessitated the application of an empirical factor(1) which is always undesirable to the true research scientist, if not to the commercial analyst.

Test 271: Caterpiller Model 30 (Distillate), Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …
