The Post-Kansan Geologic History Of The Lower Platte Valley Area, Gilbert Carl Lueninghoener

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

This investigation is essentially a geomorphological study of the lower Platte River Valley area in eastern Nebraska. The area comprises Saunders, Dodge, Washington, Douglas, Sarpy, and Cass counties. The area defined above is one of the most critically located of any for the study of the post-Kansan history of the lower Platte River Valley. It lies between the older till (Nebraskan and Kansan) borders to the west and the younger till (Illinoian, Iowan, and Wisconsin) borders to the east. Physiographic changes have therefore transpired in a strictly post-Kansan periglacial region. The Kansan till is the youngest in the area. The …

Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea

Bachelors Theses and Reports, 1928 - 1970

The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Re­fining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transporta­tion facilities, only the upper portions of a few lodes were exploited by the early miners.

Kibbey Sandstone In Montana, Glen Shean

Bachelors Theses and Reports, 1928 - 1970

Much attention has recently been given, by geolog­ists, to prolific water bearing horizon and a potent­ial oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some local­ities the sandstone is dry, and its identification in cut­tings from deep wells has in many cases proved difficult.

The Ruby Gulch Mine, owned and operated by the Ruby Gulch Mining Company, Zortman, Montana, is one of the most important low-grade gold producers in the state. Sit­uated in the Little Rocky Mountains, the mine has had an interesting history since its discovery shortly before the turn of the century.

Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken

Bachelors Theses and Reports, 1928 - 1970

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.

Upper Cretaceous Sediment In Montana, Frank J. Frankovich

Bachelors Theses and Reports, 1928 - 1970

Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.

The Goss Lemming Mouse, Synaptomys Cooperi Gossii (Goues), In Nebraska, Edson Fichter, Merle F. Hansen

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

In the course of studies on the cestode parasites of microtine rodents by one of the authors (Hansen), specimens of mice were sent to the United State National Museum where they were identified by Dr. David H. Johnson. Two of these microtines proved to be Synaptomys cooperi gossii (Coues). These specimens of Synaptomys (U.S.N.M. Nos. 282343 and 282344), collected at Lincoln, Lancaster County, Nebraska, on September 16, 1946 (male) and November 20, 1946 (female), respectively, are the first ones to be identified from Nebraska.

Studies In The Determination Of Iodine In Soils Organic Materials, And Waters, Russell T. Lundell

Theses and Dissertations

A summary of the literature on the nutritional value of iodine in the diet of various forms of life is given. The majority of evidence indicates that iodine is an essential element in plant and animal nutrition. It functions particularly in animal metabolism in the form of thyroxine. The occurrence of iodine in a nature has been briefly discussed. Investigations made in this regard indicate iodine to be almost universally distributed in very minute amounts. Most iodine salts are soluble in water and their distribution is affected by water movements. Results of iodine determinations made during the course of this …

The Effect Of Some Electrolytes On The Critical Solution Temperature Of The Phenol-Water System, Donald Gerald Leavitt

Bachelors’ Theses

A classical example of a system of liquids exhibiting partial miscibility is the phenol-water system. One of the earliest binary systems of this type to be Investigated, it has been the subject of much research and experimentation during the past sixty years. Its critical solution temperature has been determined by a multitude of investigators, the effect of a third component upon the system has been studied and many generalizations concerning partially miscible binary systems have been derived from these undertakings.

The studies which have been carried on regarding this system have been chiefly of theoretical interest, although in recent years …

The Synthesis And Some Physical Properties Of Certain Aromatic Fluorides, John W. Weldon

Bachelors’ Theses

The late discovery of methods of introduction of fluorine into organic compounds has retarded to some extent the commercial use of organic fluorides. The indirect methods used also prevented general preparation of fluorocompounds. However, the characteristic stability of many fluorine compounds has warranted both the preparation of numerous aromatic and aliphatic fluorides as well as a search for new methods of preparation. It 1s the purpose of this thesis to delineate the present methods of synthesis of aromatic fluorides and to show the influence of the substitution of fluorine on some of the physical properties of aromatic compounds.

An Investigation Into The Adaption Of The Induction Furnace For Determining The Equilibrim Diagram Of The System Cu2s-Fes, John R. Cole

A Preliminary Investigation Of The Hydrometallurgy Of Philipsburg Manganese, W. L. Goodman

Bachelors Theses and Reports, 1928 - 1970

In the past the steel industry of the United States has depended almost wholly on imports for its supplies of manganese. Although it is well known that there are enormous deposits of low grade manganese ore in the United States the production of substantial amounts of ferro-grade mater­ial from domestic sources presents a field for con­structive and practical research.

The Determination Of Interfacial Tension Using Pendant Drop Method, Katherine Tellor

Bachelors’ Theses

Boundary tension is a measure of the free energy of a fluid interface. It is a term derived from the superficial analogy between the surface of a liquid and a stretched membrane. Just as the potential energy of a fluid mass in foot pound per pound is spoken of as a "head" in feet, so it is useful to speak of free energy of a fluid surface in ergs per square centimeter as a "tension" in dynes per centimeter.

A change has been taking place in the brewing industry during the last few years. There has been a tendency to give up traditional methods of brewing for methods based on sound scientific principles. In line with this, the work of the chemical research laboratory has grown from almost nothing Until it now plays a role of vital importance to the industry.

The Determination Of Of Bromo Acid, Genevieve M. Stein

Bachelors’ Theses

The use of bromo acids in lipstick is comparatively recent. Since its use is so necessary to the modern lipstick in order to impart indelibility and staining power, the fact that bromo acid arouses a toxicity in the presence of castor oil in some individuals does not keep it from being one of the most important constituents of the stick. However, in order to keep the toxicity down to a minimum it is necessary to keep the type end amount of bromo acid under control. It is, therefore, highly important that a check on the amount of bromo acid be …

Physical And Chemical Properties Of Soil Profiles Of The Burchard And Steinauer Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to report an investigation of the soils mapped as types of the Burchard and Steinauer series. Burchard soils are described as nearly mature Prairie soils, and Steinauer soils as Lithosols, by the Division of Soil Survey. The C horizons of soils of both series consist of calcareous glacial drift. A part of the conclusions drawn from the investigation of these soils is based upon observations made in the field in southeastern Nebraska, the remainder upon laboratory data for samples taken by horizons from nine profiles.

Malonic Acid Synthesis, Mary K. Hormuth

Bachelors’ Theses

The search for new organic compounds, the discovery of their proper­ ties and the utilization of them, both in the industrial and the biological field has always been the challenge to the organic and research chemist. In particular, the study of fatty acids and their related compounds has been the particular problem to not only the physiological chemist, but also the industrial chemist. The research in this direction has tremen­dous possibilities tor only the even carbon and normal chain acids have been isolated in nature. Here difficulty is often met when trying to establish and identify this type of acid …

Range Land Of America And Some Research On Its Management, Laurence A. Stoddart

Faculty Honor Lectures

Although grazing of livestock has been a practice and a profession of man almost from his beginning only recently has range management reached anything approaching a pre~ cise science. Although ' trials and errors over the years brought to light much practical methodology for assuring high production from grazing land, still it remained for the plant physiologist and ecologist to find the whys and wherefores, and to advance new methods and new thoughts which promise to increase productivity still further and at the same time maintain the great range resource.
