Tetrazolium Salts, Andrew Garnett Richardson

Master's Theses

Tetrazolium salts, as the name indicates, are quartenary. Substitution is possible on positions 2, 3, and 5 of the ring as is shown in type formula (I). When these substituent groups are bifunctional ditetrazolium salts of types (II), (III), and (IV) result. Compounds bridged at both R' and R'' at the same time are theoretical possible, but no such cases have been reported, probably on account of the practical limitations of synthesis. The anion, which is indicated by X, may be halide, sulfate, acetate, picrate, succinate, thiocyanate, or practically any atom or group capable of existing as a negative ion.

Chelation Of The Transition Metal Ions With A Series Of Polyhodrozyamine Compounds, William Percy Moore

Master's Theses

Chelation was reviewed with emphasis on the work done by contemporary workers.

The following polyhydroxyamine compounds were synthesized, purified and· analyzed:

1,2-bis[tris(hydroxymethyl)methylamino]ethane dihydrochloride

1,3-b1s[tris(hydroxymethyl)methylamino]propane dihydrochloride

1,3-b1s[tris(hydroxymethyl)methylamino]-2-propanone dihydrochloride

1,2,3-tris[tris(hydroxymethyl)methylamino)propane tri­ hydrochloride

The latter two compounds have not been reported in the literature.

Chelates were prepared by reacting the above compounds, and 1-3bis[tris(hydroxymethyl)methylamino]-2-propanol dihydrochloride ("disec") and the "disec" free base, with the ions of the first transition metals. Stability cons­tants were obtained where appreciable coordination occurred before precipitation of the metallic ion took place . A list of the metal ions studied with one or more chelating agents follows: Cu⁺², …

Geothermometry At The Balmat No. 2 Mine, New York By The Fes-Zns System, Bruce R. Doe

Masters Theses

"Definition Of The Study. The study consists of an investigation of the variation in the temperature of formation of sphalerite on the 500 and 1500 ft levels of the Balmat zinc deposit at Balmat, New York. A subsidiary investigation was performed on the use of x-ray fluorescence as a means of chemical quantitative analysis. Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are …

A Study Of The Chelation Of 1,3-Bis (Tris (Hydroxymethyl) Methylamino) 2-Propanol With Iron (Iii), Jane Bell Grinnan Gladding

Master's Theses

The element Iron is so important that a major era of history bore its name. Its magnetic and metallic properties have long been studied and used. It is also well known that iron. is the cental element in the oxygen-carrying compound hemo­ globin and therefore essential to life. Its biological importance is also evidenced by its presence in the cytochrome oxidases . These important biochemical compounds are iron chelates

Fundamental research with iron chelates may therefore shed light on the operations of certain enzyme systems, drugs and poisons. Analytical chemistry and the dye industry have used chelate compounds for many …

Classification Of Oligocene Sediments In Nebraska: A Guide For The Stratigraphic Collecting Of Fossil Mammals, C. Bertrand Schultz, Thompson M. Stout

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

The Chadron and Brule formations constitute the White River Group in Nebraska and adjacent states. The Brule is divided into the Orella and Whitney members. The latter members are referred to the Medial and Late Oligocene (equivalents of the European Stampian and Aquitanian), while-the Chadron is equated with the Early Oligocene (Sannoisian). Each unit in Nebraska is subdivided into three parts (Lower, Middle, and Upper; or A, B, and C for the Chadron and Whitney, and A-B, C, and D for the Orella). Key beds such as fossil soils (paleosols), Purplish White beds, and volcanic ash layers, when considered with …

Geology Of A Portion Of The Hand Mine, Argenta Mining District, Beaverhead County, Montana, John Thomas Richards

Bachelors Theses and Reports, 1928 - 1970

The Hand Mine is located in the Argenta Mining District near the town of Argenta. The area surrounding the Hand Mine is characterized by intense thrusting, folding, and igneous activity. The area mapped by the author is in the southeast portion of the mine and differs from the rest of the mine in that no commercial ore has been found. The writer concludes that the steep faulting and flatlying bodies are of two different ages, and that intense oxidation has altered the ore minerals to plumbojarosite.

Oxidized Copper Mineralization Along The Continental Fault Near Butte, Montana, Theodore H. Eyde

Bachelors Theses and Reports, 1928 - 1970

Located in the fault zone of the Continental fault near the western edge of Boulder batholith of southwestern Montana the oxidized copper deposits are developed by three open pit mines, one of which is a presently in operation. Copper has been deposited by descending cold solutions which have leached copper from the surrounding quartz monzonite and deposited within the crushed fault zone. Local high grade 'bunches' of ore occur along narrow limonite veins, remnants of primary sulfide veins which have been enriched by the descending cold solutions.

The Salt Lake Group In Cache Valley, Utah And Idaho, Robert D. Adamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah …

Birds Of Jasper National Park, Alberta, Canada, Ian Mctaggart Cowan

Other Publications in Wildlife Management

Jasper Park, with an area of approximately 4 200 square miles, is the largest accessible primeval wildlife sanctuary on this continent and as such its bird lite is of the greatest interest. The meagre available records of earlier conditions indicate that noteworthy changes in the park's avifauna have taken place in the last ,0 years. There can be little doubt that other changes will take place during the years to come. For this reason, then, if tor no other, it seems desirable that as complete a record as possible of the current situation be made, for only against it can …

Various chemical and electrolytic separation methods were investigated in an attempt to separate the in­clusions in Armco ingot iron. Residues obtained were X-rayed for identification purposes. The microstruc­tures of this iron were studied with the object of de­termining the relative sizes, locations, and possible compositions of the inclusions.

The Chromatographic Purification Of Human Red Blood Cell Acetylcholinesterase, Richard P. Dunkley

Theses and Dissertations

A process of column chromatography of human erythrocyte acetylcholinesterase, using a cationic exchange resin, was investigated as a possible method for the primary partial purification of the enzyme on a large scale. The investigation was based, first; on a detailed study of the enzymatic stability to variation in hydrogen-ion and salt concentrations for periods of time extending to forty eight hours and, second; on an investigation of the degree of adsorption by the resin of the enzyme at various pH values within the pH range of enzyme stability. A method for the analysis of the enzyme activity of large numbers …

The Synthesis Of 10-Methyl-3, 4-Benzpyrene And 8,10-Dimethyl-3, 4-Benzpyrene, Jules Adelfang

Chemistry and Chemical Biology ETDs

In 1953 Cook, Hewett, and Rieger found a highly carcinogenic hydrocarbon in coal tar. By a variety of solvent extraction methods, fractional distillation, and crystallization several pure hydrocarbons were isolated from the crude pitch. Two new pentacyclic aromatic hydrocarbons were isolated and since only small quantities of them were available it was decided to ascertain their structures by synthesis instead of degradetive experiments. The hydrocarbon samples were obtained with great difficulty from two tons of crude pitch. The problem was simplified since ten of the possible fifteen pentacyclic hydrocarbons were known. From certain similarities of these hydrocarbons to perylene its …

Biological Oxidation Of Copper Sulfide Minerals, Delmar Boyd Davis

Theses and Dissertations

This work represents a study of the biological oxidation of copper sulfide minerals. The principal objective of the study was to determine the extent of bacterial oxidation on copper containing sulfide minerals. It was also desired to determine if the bacteria could oxidize copper sulfides in the absence of iron. A better understanding of the nitrogen requirements of the organisms was desired. Minerals used in this study were Bingham Canyon Float Concentrate, chalcopyrite, covellite, calcocite, bornite, tetrahedrite, and reagent grade copper sulfide. The bacteria used were obtained from the mine waters of Bingham Canyon, Utah. To study the problem the …

On The Continuity Of The Real Roots Of An Algebraic Equation, Melvin Henriksen, John R. Isbell

All HMC Faculty Publications and Research

It is well known that the root of an algebraic equation is a continuous multiple-valued function of its coefficients [5, p. 3]. However, it is not necessarily true that a root can be given by a continuous single-valued function. A complete solution of this problem has long been known in the case where the coefficients are themselves polynomials in a complex variable [3, chap. V]. For most purposes the concept of the Riemann surface enables one to bypass the problem. However, in the study of the ideal structure of rings of continuous functions, the general problem must be met directly. …

Application Of The Polaroid-Land Process To Radiographic Inspection Of Wheat, Max Milner, Robert Katz, M. R. Lee, W. B. Pyle

Robert Katz Publications

At a time when the technique of X-ray inspection of grains for internal insect infestation, announced almost two years ago, appears to have gained considerable currency in industries handling and processing grain, there exists the general feeling that these industries would be more receptive to any technique which would even further simplify and expedite the radiographic inspection process. To this end Kansas State College and the Picker X-Ray Corporation have engaged in a cooperative study relating to the application of the Picker-Polaroid photographic process to the determination of internal infestation in grain. This process is based on the principle of …

A Study Of Petroleum Resources, Production And Consumption In The United States And Foreign Countries In Their Relation To Our National Welfare And Security, Ann Frazier

Student Scholarship

This document, submitted by Ann Frazier in 1953, presents a comprehensive study of petroleum resources, production, and consumption within the United States and foreign countries, specifically examining their relationship to national welfare and security. The research highlights that while the United States was the world's leading consumer and producer at the time, accounting for over half of global oil production and roughly sixty percent of consumption, its domestic reserves were a waning asset that could not be renewed. The author challenges the alarmist view of imminent exhaustion by distinguishing between proved reserves and total resources, noting that vast quantities of …

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

Internal Fissuring Of Wheat Due To Weathering, Max Milner, J. A. Shellenberger, M. R. Lee, Robert Katz

Robert Katz Publications

Radiographic technique developed at this Station for the determination of internal or hidden insect infestation in stored grain has proved to be useful for the detection of other physical anomalies in grains. Practical applications of this sort include the detection of cracked or broken kernels in rough rice (paddy) prior to milling as well as the extent of internal fracturing of certain grains such as maize due to uneven stresses arising from severe drying conditions. This communication deals with a condition of internal fissuring occurring in wheat due to weathering of the ripened grain in the field.
