Coal In Montana, Clifford A. Barkell

Bachelors Theses and Reports, 1928 - 1970

Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 4₁000,000.00 annually.

On The Production Of Polyploidy With Paradichlorbenzene, Mary Anne Carey

Bachelors’ Theses

The subject of polyploidy has been of scientific interest for some time. The true nature of the cause of this phenomenon has been disputed ever since its existence was made known. Polyploidy is the condition in which the haploid number of the chromosomes, contained within the nucleus, is multiplied so that there is a higher number of chromosomes present than there is in the typical diploid cell of that particular plant or animal. The diploid number of the chromois known as 2n, therefore, higher multiples would be referred to as 3n, 4n, 8n etc. Some plants or animals have one …

Upper Mississippian Faunas Of Western Montana, James King

Bachelors Theses and Reports, 1928 - 1970

The author has made a study of an assemblage of fossils from the Blacktail Range near Dillon Montana with the purpose in view of attempting a correlation of that group with the fauna of the Big Snowy Group. Fossils have also been obtained from a limestone formation in northwestern Montana and from four different areas in the Amsden formation in central and western Mont­ana.

Stratigraphic Studies Of The Ordovician And Devonian Formations Throughout The Northwest Plains Area, Walter N. Campbell

Bachelors Theses and Reports, 1928 - 1970

As yet the knowledge of Ordovician and Devonian physiography in this vast northwest region remains almost a complete secret. Very little, in any, work has been done along this line with the exception of those areas where the various formations outcrop.

An Investigation Of The Age-Hardening Of Copper With Nickel-Boron Compounds, Robert I. Moreen

Bachelors Theses and Reports, 1928 - 1970

Boron is an element whose metallurgical possibil­ities have never been fully investigated. The principal reason for this fact seems to lie in the difficulties encountered in preparing elemental boron and its various intermetallic compounds.

Parabos Dodsoni Barbour And Schultz: A Correction, Erwin Hinckley Barbour, C. Bertrand Schultz

Department of Earth and Atmospheric Sciences: Faculty Publications

A Bos-like animal, Parabos dodsoni, was recently described by Barbour and Schultz (1941, "A New Fossil Bovid from Nebraska", Bull. Univ. Nebr. State Museum, Vol. II, No. 7, pp. 63-66, Figs. 24-27, December) as a new genus and species from the Pleistocene of Nebraska. Attention has been called to the writers by Dr. E. H. Colbert of the American Museum of Natural History that the name Parabos is preoccupied. Parabos was introduced as a generic name by C. Arambourg and J. Piveteau (1929, "Note preliminaire sur un Ruminant du Pliocene inferieur du Roussillon," C. R. Bull. Soc. Geol. de …

The Cleaning Action Of Detergents And Soaps On Printer's Ink And Lubricating Oils, Daniel David Holzman

Bachelors’ Theses

During the past few years, industry has developed a steadily increasing interest in certain new types of synthetic organic compounds.

Industry devoted to the cleaning of textiles has found the removal of printer's ink and lubricating oils a tedious operation.

There has been developed and perfected a series of synthetic materials which successfully meet modern needs.

The detergents, in general, have some or all of the following properties: wetting-out, dispersing, emulsifying, penetrating, and cleaning.

There seems to be a need to investigate some of these new detergents for commercial cleaning purposes.

A Review Of The Daimonelix Problem, C. Bertrand Schultz

University Studies (University of Nebraska) (1888–1984)

THE first paleontological expedition of the University of Nebraska State Museum was organized in the summer of 1891 and was led by Erwin H. Barbour, now Director Emeritus of the Museum. The most important and interesting discoveries made during the season were some very peculiar spiral fossils called by the field party "Devil's Corkscrews," or Daimonelix,l which were found in the Miocene deposits near Harrison in Sioux County, Nebraska. During the fifty years that have intervened scientists have tried to determine the origin of these strange forms. Several controversies arose, and although various theories have been proposed, none as yet …

The Origin Of Daemonelix, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

Attention is called to the controversy of some years ago over the origin of the "Devil's Corkscrews." The problem may have appeared unimportant then, but now a correct understanding of the paleoecology of Harrison time may hinge on the explanation of these strange "fossils." The characteristics of Daemonelix are briefly reviewed, they are compared to the lianas of the modern tropical jungle, and the postulated conditions of Harrison sedimentation are believed to supply an adequate explanation for the presence of fossil rodent remains in the Daemonelices. The possibility of a vegetal origin of these fossils is believed to be demonstrated.

Activity Of Papain On Gelatin Mixtures, Edward J. Ruschmann

Bachelors’ Theses

Within the Marquette chemical laboratories under the direction and supervision of Dr. John R. Koch, professor and head of the Chemistry Department, many noteworthy advances in enzyme chemistry have been achieved. A new type all glass, single unit viscometer was developed and perfected by Koch and now is the basis of the study of enzyme activity by viscometric methods. The use of this viscometer is not limited solely to work in these laboratories but has also been used with great success in bating and brewing.

The Conversion Of Certain Amino Acids To Carbohydrate In Normal Animals, Bergere Alfred Kenney

Chemistry and Chemical Biology ETDs

Among the earliest problems which interested the physiological chemist was that of the possibility of an interconversion of the major types of food-stuffs. That this conversion actually does take place in the case of carbohydrates changing to fats has been apparent, ever since Man began to fatten his domestic animals on a starchy diet. However, interconversion of the other types, such as that of fats to carbohydrates and proteins, or carbohydrates to proteins, and of proteins to carbohydrates and fats, is not so obvious, and even now, after many years of experimen­tation, the answer to the question is far from …

Concrete And Cement Surface Coatings, Gabriel J. Popovich

Bachelors’ Theses

It has been with difficulty that precise information of any kind regarding the surface coating of concrete and cement finishes had been found. In fact, there was limited information to be found after 1930. Having but a short time to conduct any research, it was impossible to delve too deeply into this branch of the thesis. It is sincerely hoped that in the very near future a more thorough, extensive and comprehensive study can be made on this subject. The purpose of this thesis is to determine the best composition of concrete and the best surface coating for it and …

A Study Of The Amino Nitrogen In Various Gelatins By Means Of The Ninhydrin Reaction, Wilma Jane Thrush

Bachelors’ Theses

Experimental work and study has shown that the activity figures measuring the effects of proteolytic enzymes, such as, pepsin, trypsin, and papain are not the same for the various gelatins used as substrates.

The Effect Of Time, Temperature, And Pressure On The Hydrogenation Of A Mixture Of Linoleic And Oleic Acids, Gordon S. Wepfer

Bachelors’ Theses

During the past few years interest and experimentation in the field of hydrogenation of different fats and oils has increased enormously. Strides made in the oil-hardening industry have surpassed all expectations. These advances were brought about by simplifying old methods and creating new ones. The probable reasons for this impetus in research is due to the fact that unexpected uses for hydrogenated oils and fats have been found and will continue to be found. With the increase in use of these products the market for them will also increase. Recently, the resin industries have produced useful products by condensing pure …

The Study Of The Physical And Chemical Factors Influencing The Plankton In The Menomonee River, Hermoise Katz

Bachelors’ Theses

The reasons for the choice of this study are several in number. Previous collecting trips had shown to some extent the relatively high productivity of organic life in this stream. From superficial external evidence, however, it seemed likely that the stream should contain some degree of pollution. The contradictory nature of these two observations called for furthur investigation. Then too, the nearness of the location of the Menomonee River to Marquette University contributed to the facility of such an investigation, and also pointed to the possibility that such a survey might be of some use to the Department of Biology. …

A Study Of Resins From Carbohydrates, Edward F. Sullivan

Bachelors’ Theses

The availability of large amounts of carbohydrates, and the need in the past years of larger markets for the available supplies of sugar have lead a number of sugar companies to investigate the possibilities of synthetic resins from carbohydrates. Although in the last ten or twelve years, a number of steps have been taken in the investigation of sugar resins, the information available has been restricted to a few patents. Consequently, information on the chemistry of the problem has been neglected. Thus, this work, for the most part, covers partially the possibilities of producing alkyd resins from saccharides, as well …

Solubilities Of Glycerides, Alois L. Wagner

Bachelors’ Theses

The mono, di, and triglycerides have many uses in industry; each of these glycerides has a specific purpose, if not directly, then as an intermediary compound .in the synthesis of a glycerol derivative. In order to obtain the highest efficiency in a synthesis, or as a matter of fact, in any phase of chemistry, the production of a homogeneous result demands the use of pure uniform constituents.

The Effects Of A Carbohydrate Deficient Diet On The Mouse, Walter Rudolph Sala

Bachelors’ Theses

Deficient diets have been used extensively as the basis for zoological experiments concerning the metabolism, and dietary requirements of individual animals. The majority of this work has been carried on with the rat as the subject, and resulting external physical variations as the experimental aim. The writer used the mouse as his subject, but, since no literature was available concerning this animal, a few similar experiments performed on the rat will be cited.
