Geology Of The Ozark-Martin Mine Area, Madison County, Missouri, William Clifton Hayes

Masters Theses

"General descriptions of the region adjacent to the Ozark and Martin Mines of Madison County, Missouri have been included in a number of early publications dealing with the Einstein Silver Mine area, but a detailed geologic map has not been made. It was thought that through detailed mapping and by a detailed analysis of all of the geologic features present, a more definite relationship between mineralization and structure might be determined"--Introduction, Purpose and Scope of Work, page 1.

An Investigation Of The Colorimetric Methods For The Determination Of Fluorine By The Zirconium Alizarin Sulfonate Method, William Lewis Break

Masters Theses

"There has been a need for a rapid and an accurate method for the determination of fluorine in its compounds. Both gravimetric and volumetric methods have been studied, but both methods were time consuming or inaccurate or both. Colorimetric methods had been studied before F. Richter developed his method but none had been reported to be as satisfactory as his method. This method was investigated because it was thought that F. Richter's method would be a satisfactory colorimetric determination for fluorine in its compounds"--Introduction, page 1.

Geology Of The Einstein-Apex Tungsten Mine Area, Joel B. Pomerene

Masters Theses

"The geological problem existing in the Silver Mine area, the relationship of mineralization to structure, particularly to faulting and jointing, was pointed out to the writer by Prof. O. R. Grawe. Several geologists have made reconnaisance [sic] surveys of the whole region, but so far no detailed geologic map has been published of the immediate area. Prof. Grawe pointed out that such a map would be of value in the better understanding of the area and would be especially useful in the event that another national emergency required the development of all possible sources of tungsten"--Introduction, Selection of the Problem, …

The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter

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

THE GEOLOGIC history of the bison in North America is a subject which has received little attention to date. Osteological rather than geological problems have been the main concern of most writers who have so far published. If the geologic history of the bison is to be learned, it will be necessary to devote more time and effort in the field in determining the age of the deposits in which various specimens have been discovered and in making more extensive collections from deposits of known age. Unfortunately the majority of the type specimens have been surface finds and little attempt …

An Investigation Of The Meaning Of Α3 As A Measure Of Skewness, John W. Coy

Mathematics & Statistics ETDs

The purpose of this study is the interpretation of α₃ by means of a relatively simple formula which will predict the amount of shift in the effective limits of the Type III curve for a given change in the skewness. The methods used are chiefly empirical.

The Synthesis And Certain Chemical Properties Of Several Aromatic Fluorides, Horst G. Schneider

Bachelors’ Theses

The preparation of organic fluorides, until only recently, had been seriously curtailed not only because of the difficulty experienced in their synthesis, but also due to the lack of information with regard to their physical and chemical properties. With the investigation of their characteristics, their great importance was for the first time fully realized. A concerted search was made for new modes of their preparation. That this search was rewarded is shown in part by the synthesis of several aromatic fluorides as a portion of this thesis.

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 …

A Study Of Retention Of Percentage, Fred Dellett

Master's Theses or Doctor of Nursing Practice

The problem of this thesis was to determine by means of a test the retention of the fundamentals of percentage as shown by beginning eighth grade pupils, who were taught percentage the previous year in the seventh grade. The fundamentals of percentage are here considered as the changing of percents to decimal fractions or common fractions, the reverse procedures, and the three types of problems arising from the relation, base times rate equals part. These quantities, base, rate, and part, are represented in the example, 300 X 12% = 36, respectively. Because of the inherent relationship of decimal fractions and …

Geology And Ore Deposits Of The Dunmore Mine, Ouray County, Colorado, Caswell Silver

Earth and Planetary Sciences ETDs

The Dunmore lode is located near Ouray, Colorado in the northwest part of the San Juan Mountains. In structure as well as mineral assemblage it shows a connection between the chimneys and veins of the region. The lode averages about 100 feet wide for 1,200 feet along the Dunmore claim. The fissure zone is over two miles long and displacement along it has offset a folded pre-Cambrian complex 4,500 feet prior to the deposition of 2,400 feet of volcanic tuff. Fissures in the pre-Cambrian rocks controlled in part the intrusion of dikes and the formation of veins. Late Tertiary faulting …

Microradiography With Metal Powders, Wallace Kluck

Bachelors’ Theses

Microradiography is a comparatively recent development in the X-ray field. The term applies to the analysis of a thin specimen by photographing it with X-rays and subsequently enlarging the photograph to bring out minute structural elements. A microradiograph has several advantages over a photomicrograph. First of all it goes beyond the surface and reveals the internal structure of the specimen, a more important advantage at least as concerns this paper is the ability of the microradiograph to enable one to accurately determine the chemical elements making up the specimen.

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 …

A Study Of The Lassaigne Test For Nitrogen, Marion Ann Stout

Bachelors’ Theses

The elementary analysis of an organic compound is a determining factor in the characterization of the compound. The problem of this analysis was first encountered in organic characterization class where it was impossible to obtain a satisfactory test for nitrogen using the Lassaigne Method. It is the purpose of this thesis to testout the Lassaigne method under various conditions and to determine a set of conditions hereby the test will be positive.

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

Economic Talc Deposits Of Montana And Related Firing Problems, Charles J. Lyden

Bachelors Theses and Reports, 1928 - 1970

This thesis has to do with a study of the produc­tion of talc in Montana, describing the local geology of each deposit, and a description of the laboratory tests that were made on various grades of Montana talc in an attempt to determine why some grades of talc can be burned in solid forms while others must be ground, mixed with a binder and molded.

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.
