A Theorem On The Unit Groups Of Simple Algebras, Ralph Hull Jan 1944

A Theorem On The Unit Groups Of Simple Algebras, Ralph Hull

Department of Mathematics: Faculty Publications

Let k be an algebraic number field of finite degree m and let A be a normal simple algebra of degree n, order n2, over k. Our object is to prove the following theorem.
THEOREM. If A is an R-algebra, that is, if n>2 or at least one infinite prime place of k is unramified in A when n=2, then any two distinct maximal orders of A have distinct groups of units.

The Effect Of Boron On The Hardenability Of Steel, William J. Foy May 1943

The Effect Of Boron On The Hardenability Of Steel, William J. Foy

Bachelors Theses and Reports, 1928 - 1970

Many attempts have been made to improve iron and steel and their alloys by the addition of boron. The re­sults obtained were not encouraging for the reason that the amount of boron used, generally from 0.2 to 2.0 per cent is altogether too high. This percentage of boron ren­ders the product hard and brittle and of late the experiments with boron in this connection have been practically abandoned.

A Cytolocical Study Of The 4th Chromosome Of Eyeless Drosophila, Joyce Ruth Soelch May 1943

A Cytolocical Study Of The 4th Chromosome Of Eyeless Drosophila, Joyce Ruth Soelch

Bachelors’ Theses

In Drosophila Melanogaster the recessive gene for eyeless and its normal allelomorph, which cause in general a redaction of the size of the eye in the adult fly, are situated in the small 4th chromosome. The purpose of this experiment was to make a Cyto- logical study and comparison of the 4th chromosomes of the eyeless Drosophila and the normal plus or wild type to determine whether this recessive gene, located on the 4th chromosome, results in a difference in the number, size, formation, or location of bands.


A Suggested Method For The Measurement Of Unsaturation In Organic Compounds By Means Of A Hydrogen Number, Richard Roberts May 1943

A Suggested Method For The Measurement Of Unsaturation In Organic Compounds By Means Of A Hydrogen Number, Richard Roberts

Bachelors’ Theses

The measurement of unsaturation in organic compounds are commonly expressed in terms of an iodine number, but as this value is not trustworthy in a number of cases, it has been suggested by earlier worker that an indication of unsaturation could be obtained by the quantitative hydrogenation of a compound and expressing the result in terms of a hydrogen number. Although such determinations have been previously made, usually at elevated temperatures and pressures, it is the purpose of this work to carry out the hydrogenation at room temperature and atmospheric pressure. For purposes of comparison, determinations will be made at …

Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma Nov 1942

Missourian Triticites Of The Northern Mid-Continent, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

The tendency toward fine discrimination in fusulinid species has made necessary standardization in their study. Theories and practices of fusulinid study are herein discussed in some detail. Four new species of Triticites are described from the Missouri series of the Pennsylvanian system; one species from the Virgil series and two froim the Missouri are redescribed, and the characters of the other five known Missourian species from the northern mid-Continent are shown in graphs, thus bringing together the known Missourian species. Finally consideration is given to the ontogeny and phylogeny of the group.


A Research In Sixth Grade Children's Solution Of Verbal Arithmetic Problems, Herbert Schroder Jun 1942

A Research In Sixth Grade Children's Solution Of Verbal Arithmetic Problems, Herbert Schroder

Master's Theses or Doctor of Nursing Practice

The purpose of this research in sixth grade children's solution of verbal problems in arithmetic is to investigate the mental processes that lie back of pupils' answers in arithmetic. That is, how do pupils solve verbal problems in arithmetic? The investigation involves several related problems such as; to what extent is the pupils' method of solution influenced by irrelevant data, cues, details, and numbers used in a problem?

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 May 1942

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.
