Thickness And Structural Study Of Major Divisions Of Cretaceous System In Nebraska, Paul Fuenning

Department of Earth and Atmospheric Sciences: Faculty Publications

The purpose of this paper is to present isopach maps of certain stratigraphic divisions of the Cretaceous system and structure-contour maps of certain horizons of that system in Nebraska. Tables of factual data also are included. The maps indicate clearly that certain structural "highs" such as the Chadron-Cambridge axis and the Sioux Falls "high," in conjunction with a large well defined basin across central Nebraska and another deep basin west of the Chadron-Cambridge axis, dominated the structural and depositional history of Nebraska during the Cretaceous period.

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 ) …

A Study Of The Electrolytic Reduction Of Pyrrole, Don Richard Strehlau

Masters Theses

"A review of the chemical literature has shown that electro-organic methods compare favorably with purely chemical methods for certain syntheses belonging to the following general classes of reactions: coupling, oxidation, reactions with halogens, and reductions. Electro-organic methods have been used most successfully in synthesis by reduction. The chief advantage is using electrolytic reduction in preference to a chemical one is that it offers a more exact control of conditions, and consequently should give a higher yield and a purer product. The advantages of the means of reduction suggested an investigation of its use in the synthesis of hydrogenated products of …

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.

The Magnesium Content Of The Rocks Of The Upper Cretaceous System Of Ellis And Osborne Counties, Kansas, Robert Funston

Master's Theses or Doctor of Nursing Practice

The recent impetus given industry by the national defense emergency has made everyone more or less conscious of the great importance of minerals. During the past few years some of the industrial leaders of Kansas have been attempting to promote the natural resources of the state. Some minerals once considered of little or no value are now being developed. For many years the limestone rocks of Western Kansas have been used for building purposes. Until recently little work has been done on the chemical composition of these rocks. The author has decided to continue the study by analyzing the rocks …

A Study Of The Transparency Of Paraffin Wax, Gordon B. Smith

Bachelors’ Theses

The problem of wax transparency with which this thesis is concerned interested the author as a result of past experience with a bakery firm. The practical application of a positive solution to this problem would be as a competitor of cellophane, that is, transparent paraffin used for commercial wax paper would combine the quality of keeping bakery goods fresh with the display value of cellophane.

A Study Of The Bright Nickel Producing Properties Of Tergitol Penetrant 4, Maurice F. Murphy

Bachelors’ Theses

For many years, it has been known in the plating industry that certain metal baths were affected when materials called ’'addition agents” were added. The addition agents were usually organic and had high molecular weights. Nickel is especially sensitive to the presence of such foreign substances, a very bright deposit being obtained upon the addition of small amounts of gum, gelatin, glue, gum tragacanth, gum arabic and similar materials. These substances have, however, proved unsatisfactory because of difficulty of control and because of decomposition of the agent.

In the past ten years a new type of bright nickel bath has …

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.

Will Russia Win The War?, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

As this is written, Russia is not in the war; nevertheless, she may eventually win the war. It may not be immediately, it may not be for a generation, it may not be for fifty or more years, and it may be very soon. The "War" may not even be the present holocaust which engulfs Europe; but eventually Russia may win, even though new battles may be won and lost and perhaps much more blood spilled in the meantime; even a German victory may intervene with far-flung domina- tion in all of the continents.

Russia possesses unmeasured elements of strength …

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 …

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 …

Studies Arising From A Problem In The Calculus Of Variations, John Gonzalez

Mathematics & Statistics ETDs

In mathematics, generalization is progress; so much so that oftentimes one loses sight of the fact that generalization is the result of arduous work in the consideration of the particular. In no other branch of mathematics is this better exemplified than in the Calculus of Variations. The beginning of a systematic development of the theory of the Calculus of Variations really started with the two Bernoulli brothers (1654-1748) in their discussion of the brachistochrone problem in 1696. The method devised by them were sufficiently powerful in the attack of a large number of problems. Euler (1707-85) further elaborated the geometrical …

Some Investigations On Quantitative Measurement Of Amalgamation, Charles Moore

Bachelors Theses and Reports, 1928 - 1970

Amalgamation is a process in which precious metals are collected by mercury. The exact way in which the mercury holds the other metals is not positively known. It is proba­ble that a series of intermetallic compounds form. Very little work has been done so far on the theory of amalgama­tion.

A Study Of The Effect Of Various Organic Compounds Upon The Corrosion Resistance Of Stainless Steel In Sulfuric Acid, Cyril J. Stockhausen

Bachelors’ Theses

Ever since the use of metals become a vital part of modern living, much has "been written about corrosion and its prevention. With regard to corrosion prevention by means of absorbed films, most of the study has "been restricted to experimentation either with commercial compounds of unknown composition or complex amines and sulfonates with little attention paid to a comparison of different polar groupings and the influence of metallic structure.

The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …

Stratigraphy And Paleontology Of The Eagle Formation In Montana And Adjacent Areas, Raymond Thompson

Bachelors Theses and Reports, 1928 - 1970

A conspicuous two hundred and fifty foot sandstone of central Montana, known as the Eagle Formation, constitutes part of the some five thousand feet of Cretaceous sediments in the state. It stands out in steep cliffs which stretch for many miles in the outcrop area from Wyoming to Canada.

Basic Information In The Granitic Rocks Of The Boulder Batholith, Clifford G. Sherwin

Bachelors Theses and Reports, 1928 - 1970

Dark fine grained basic masses of rock are found in nearly every part of the Boulder Batholith, these commonly being referred to as inclusions, segregations, autoliths, and various other names. The origin, distribution, and composition of the dark inclusions form the basis for this report.

Some Chromite Deposits In Madison County, Montana, Russell H. W. Chadwick

Bachelors Theses and Reports, 1928 - 1970

Chromite occurs in Madison County, Montana, in two areas, one three miles southwest of Silver Star, the other five miles southeast of Sheridan. The ore bodies are small, lenticular masses surrounded by metamorphosed sedimentary rocks of the pre-Cambrian Cherry Creek series. The ore was deposited from the hydrothermal solutions which serpentinized the surrounding metamorphic host rocks.

The Electrowinning Of Manganese From Rhodochrosite, Lloyd L. Thompson

Bachelors Theses and Reports, 1928 - 1970

Manganese is commonly known to be a metal of great strategic importance. It is essential in the production of all steels, first as a scavenger to remove oxygen and sulfur, and second as an alloying element in wear-resis­tant steels.
