The Preparation And Catalytic Properties Of Rhenium Blacks Obtained By Reduction Of Re(Vii) In Anhydrous Ammonia And Amines With Alkali Metals, David William Seegmiller

Theses and Dissertations

The purpose of the investigation was to determine the catalytic activity of rhenium blacks obtained by reduction of rhenium salts in alkali metal-ammonia or amine systems. A review is presented on the chemical, physical and catalytic properties of rhenium, and on the rhenide ion, on the nature of the alkali metal-liquid ammonia system, and the reduction of metallic salts therein. The first reduction system studied was that obtained by dissolving sodium in liquid ammonia. The salts reduced in this system were KReO_4, Re_2O_7 and NH_4ReO_4. The reduction of KReO_4 was unsuccessful, and the heptoxide was difficult to handle. The product …

A Preliminary Investigation Of The Role Of Selenium In The Growth Of Stanleya Pinnata, Richard F. Nelson

Theses and Dissertations

Stanleya pinnata has been identified as an indicator plant for seleniferous soils. The apparent limitation of its distribution to seleniferous soils suggests that selenium may play an essential role in this species. This study is a preliminary investigation of the role of selenium to Stanleya pinnata. When fully ripe, seeds germinated readily. Concentrations of selenium of 100 parts per million and 1000 parts per million retarded germination. Seeds germiuated in lower concentrations were not affected which was probably due to the selenium content of the seed itself, being greater than in the germinating media. Stanleya pinnata plants were grown from …

Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson

Theses and Dissertations

This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …

The Isomer Distribution In The Sulfonation Of Iodobenzene, Joseph A. Knight

Theses and Dissertations

Using the isotope dilution technique, the distribution of isomers was determined when iodobenzene was sulfonated with sulfur trioxide in liquid sulfur dioxide. The active isotope was S^35. Before this distribution could be established, it was necessary to prepare the pure isomers of iodobenzenesulfonic acid. These were prepared by diazotization of the corresponding aminobenzenesulfonic acids. Since o-aminobenzenesulfonic acid was not readily available, it was necessary that it be synthesized before the diazo reactions could be carried out. Considerable work has been done on the development of a method whereby the bromobenzenesulfonic acids could be synthesized and obtained in pure form. Some …

The Dehydrocyclization Of Normal Heptane To Toluene With Supported Rhenium, Platinum And Molybdenum Catalysts, Robert R. Beishline

Theses and Dissertations

The dehydrocyclization activity of supported platinum, molybdenum and rhenium catalysts was studied by determining the toluene yield from n-heptane as a function of temperature and metal concentration in the catalyst. The support was 100 to 200 mesh alumina. Metal concentrations of 0.01% to 1.0% platinum, 0.1% to 2.0% molybdenum and 0.1% to 2.5% rhenium were studied in the temperature range from 500° to 600° C. Platinum was shown to be superior to both molybdenum and rhenium at all temperatures and metal concentrations investigated. The rhenium data were somewhat erratic, but showed rhenium to be a poor dehydrocyclization catalyst. The apparatus, …

History Of The Japan Mission Of The Church Of Jesus Christ Of Latter-Day Saints, 1901-1924, Murray L. Nichols

Theses and Dissertations

The purpose of this work is of course to fulfill thesis requirements, but more important to me is a desire that those who read it may gain a greater understanding of the mission in Japan. The membership of the church seems to have shared the traditional American opinion that the Far East is of little consequence in our affairs, and have given the area little attention. Missionaries have been and still are reluctant to go there; feelings of failure have persisted because of the early experiences in Japan. However, those who have seriously given their attention to missionary labors in …

A Study Of General And Religious Personal Problems Of Tenth, Eleventh And Twelfth Grade Seminary Students, Wilson K. Andersen

Theses and Dissertations

Because it seemed likely that teachers of adolescent Latter-day Saint boys and girls might benefit from an up-to-date view about what their students are personally concered, a need was felt for this particular kind of survey. A review of the related literature indicated a dearth of material in this area, particularly in connection with Latter-day Saint youth.

A Study To Determine The Ten Most Serious Problems Of Lds Seminary Students, And What The Seminary Is Doing To Help Students With These Problems, Ortho Christensen

Theses and Dissertations

It was the purpose of this study to determine the ten most serious problems of L.D.S. Seminary students, and what the seminaries are doing to help students meet these problems.

An Early History Of Milford Up To Its Incorporation As A Town, George A. Horton Jr.

Theses and Dissertations

The first known party of white men who entered the area that became Utah included a Franciscan Friar, Silvestre Velez de Escalante. This expedition passed through the Milford Valley in the fall of 1776 and it was when they were camped at San Brigida, near or on the present site of Milford, that the important decision to turn back to Sante Fe was made.

Near the hot springs which are 15 or 20 miles farther south, Escalante recorded that the territory of the bearded Indians they had first encountered at the Sevier River extended to that point. It is not …

George Edward Percy Careless: His Contributions To The Musical Culture Of Utah And The Significance Of His Life And Works, Howard Hoggan Putnam

Theses and Dissertations

Through study of the conditions of the past one is often able to appreciate the present a great deal more. Particularly does this seem true when one looks into the early musical activities in our State of Utah. Most people are aware of the great amount of musical activities existing at the present time in Utah, but many fail to stop and realize the background of work and effort applied to bring these musical experiences before the public. Many fail to realize the pioneering work done by individuals to advance music to its present degree of performance. Names such as …

Thermal Reaction Of Hydrogen And Oxygen In Small Bore Tubes, Shib Charan Chattoraj

Theses and Dissertations

The thermal reaction of hydrogen and oxygen has been investigated from the standpoint of the important intermediate hydrogen peroxide in the region between 620-720 degrees centigrade in small bore Pyrex and steel tubes. The minimum explosion-temperatures with different flow rates and compositions of the mixture have been determined. They have been found to vary with the composition and flow rate of the mixture. The minimum explosion temperature is also found to vary with the condition of the reaction tube surface. The yield of hydrogen peroxide has been determined as a function of temperature, contact time, composition of feed stream, and …

Gastropoda From The Pierre Shale (Upper Cretaceous) Of Emmons County, South-Central North Dakota, Alan M. Cvancara

Theses and Dissertations

Fossil gastropods were studied from the upper part of the Pierre shale (Upper Cretaceous) in Emmons County, south-central North Dakota. This primary purpose of this study was to figure all gastropods found and bring the nomenclature of up to date. Secondly, an attempt was made to determine whether these fossil gastropods could be used in defining the contact between the Pierre shale and overlying Fox Hills sandstone.

Little paleontological work has been done on Pierre gastropods in North Dakota. Identification previously made seem to have been done somewhat hurriedly from Meek (1876) with little regard to modernizing the nomenclature.

These …
