The Basic Analogue Of Kummer’S Theorem, J. A. Daum
The Basic Analogue Of Kummer’S Theorem, J. A. Daum
Department of Mathematics: Faculty Publications
About one hundred years ago, E. E. Kummer proved the formula
(1) 2F1 [1 + a – b a, b; -1] = [Γ(1 + a - b)Γ(1 + a/2) ÷ Γ(1+a)Γ(1+a/2 - b)
which has since been known as Kummer's theorem. This appears to be the simplest relation involving a hypergeometric function with argument ( - 1).
All the relations in the theory of hypergeometric series rF8 which have analogues in the theory of basic serie3 are those in which the argument is ( + 1 ) …

The Origin Of Daemonelix, Alvin Leonard Lugn
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 Feeding Habits Of Gambusia Affinis Affinis, With Special Reference To The Malaria Mosquito, Anopheles Quadrimaculatus, A.D. Hess, Clarence M. Tarzwell
The Feeding Habits Of Gambusia Affinis Affinis, With Special Reference To The Malaria Mosquito, Anopheles Quadrimaculatus, A.D. Hess, Clarence M. Tarzwell
United States Environmental Protection Agency: Publications
The viviparous top minnow, Gambusia affinis affinis (Baird and Girard), has for many years been considered an important predator of the immature stages of mosquitoes. Various field workers have reported on the value of this species in controlling both anopheline and culicine mosquitoes, but few detailed studies have been made. Probably the most detailed of these has been that of Hildebrand (1925). His investigations were made during the summers of 1921-24 in the vicinity of Augusta, Ga., with the subspecies G. affinis holbrooki. Employing the common dipper method, he compared the densities of anopheline and culicine larvae and pupae in …

Measurements Of The Magnetic Permeabilities Of The Iron-Manganese Alloy System Prepared By The Methods Of Powder Metallurgy, O. Cihad Onbulak
Bachelors Theses and Reports, 1928 - 1970
Powder metallurgy is a branch of metallurgy which produces metallic compacts in their final forms by means of pressure and heat-treatment from the powders. The products of powder metallurgy are being used in our daily lives quite often. For example, the tungsten wires in the electric bulbs to the silver-tin fillings of our teeth.
The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu
The Extraction Of Chromate Salts From Montana Chromite, Server Tasdemiroglu
Bachelors Theses and Reports, 1928 - 1970
In this thesis I have tried to determine the suitable temperature, time and the amount of soda ash and lime needed for the calcining process. The leaching and purification tests were studied experimentally. The earlier process for making chromate from chromite was not the same as is used today. Therefore I have found it useful to put into this thesis the newest method for making chromate salts and their important uses.

Bachelors Theses and Reports, 1928 - 1970
The geologic history of the Holden area and Lake Chelan district is an integral part of the history of the Cascade Mountain Range. The structure is very complex and the rocks, which have been subjected to intense metamorphic action, are portions of a roof pendant and consists of gneisses, schists and quartzites that are often difficult to correlate.
Pegmatites In Southwestern Montana, Ora Rostad
Pegmatites In Southwestern Montana, Ora Rostad
Bachelors Theses and Reports, 1928 - 1970
Little has been written on pegmatites in Montana except in conjunction with reports on mining districts. This subject was chosen as a senior thesis to see what facts could be ascertained regarding pegmatites alone, and an attempt has been made by the writer to assemble all written material on pegmatites in southwestern Montana, and to study specimens from those that could be reached or from which specimens were available.
A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
A Study Of The Concentration Of A Low-Grade Manganese Ore From The Ennis District, John B. Schuettenhelm
Bachelors Theses and Reports, 1928 - 1970
The purpose of the investigation was to determine the most effective means of concentrating the manganese in the ore. The study was that of identification of the minerals present. This showed the presence of oxides of manganese and iron, and carbonates of calcium and manganese. Methods of investigation were planned to determined whether the ore could be concentrated effectively by gravity concentration methods.
A Study Of Resins From Carbohydrates, Edward F. Sullivan
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 …
The Effects Of A Carbohydrate Deficient Diet On The Mouse, Walter Rudolph Sala
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.
The Preparation Of Some Typical Organoboron Compounds, Glen David Barbaras
The Preparation Of Some Typical Organoboron Compounds, Glen David Barbaras
Bachelors’ Theses
Organoboron compounds have long been known, the first being prepared by Frankland as early as 1862. No particular interest in these compounds was aroused, how ever, because of the difficulty and expense of their preparation as well as their extreme instability. From time to time further attempts at their preparation were made and a few reactions were ob served. With the rise of modern electronic theories of chemical combination, however, organoboron compounds were discovered to exhibit properties and undergo reactions which would substantiate these theories. Consequently, since 1936 possibly over a hundred of these compounds of many different types have …
The Corrosive Effect Of Sodium Acid Sulfite Solution Upon Stainless Steel As Compared With Carbon Steel And Cast Iron, Arthur John Haug
The Corrosive Effect Of Sodium Acid Sulfite Solution Upon Stainless Steel As Compared With Carbon Steel And Cast Iron, Arthur John Haug
Bachelors’ Theses
Tilghman, in 1866, discovered the fundamental principle of the sulfite process - the treatment of wood with a solution of sulfur dioxide gas in water, with the addition of an alkaline bisulfite. However, he was unable to pursue this discovery because of the difficulty of obtaining acid resisting materials.
Permian Pelecypods In The Lower Quartermaster Formation, Texas, Robert Roth, Norman D. Newell, Benjamin H. Burma
Permian Pelecypods In The Lower Quartermaster Formation, Texas, Robert Roth, Norman D. Newell, Benjamin H. Burma
Department of Earth and Atmospheric Sciences: Faculty Publications
The age of the Quartermaster formation of Oklahoma and Texas has been the subject of some controversy, being variously given as late Permian or Triassic (?). Fossils have not been reported from these beds until the present discovery of a faunule in the lower part of the Doxey shale at the base of the Quartermaster. Three species are recognized, Naticopsis transversus (Beede), Schizodus oklahomensis Beede, and Myalina acutirostris, n. sp. These forms characterize the recently described Whitehorse fauna and indicate close relationship of the enclosing beds with the Whitehorse formation, even though the Quartermaster fossils occur more than a …

An Analysis Of Fishing In The Tva Impoundments During 1939, R. William Eschmeyer, Clarence M. Tarzwell
An Analysis Of Fishing In The Tva Impoundments During 1939, R. William Eschmeyer, Clarence M. Tarzwell
United States Environmental Protection Agency: Publications
An inventory of fishing on Norris, a storage reservoir, was begun in 1938. The following year it was extended to Wheeler, a run-of-the-river reservoir, and to the tailwater area below Wilson Dam. This inventory, therefore, covered each of the three general types of fish habitats created by the TVA dams. This discussion is a summary of the 1939 fishing data, together with recommendations for fish management based on the creel census information. The data collected totaled 34,270 usable fishing records, representing a catch of 98,495 fishes.
