Foraminifera From Outcrops Of The Pierre Shale (Upper Cretaceous) Of North Dakota, Everett E. Wilson
Foraminifera From Outcrops Of The Pierre Shale (Upper Cretaceous) Of North Dakota, Everett E. Wilson
Theses and Dissertations
In North Dakota the Pierre shale was deposited in all portions of the State except the southeastern corner, where it was either never deposited or removed by pre-Pleistocene erosion. In the western part of North Dakota the Pierre is overlain by later Cretaceous and Tertiary sediments, but to the east of the Missouri River, where it forms the bedrock, it is mantled by glacial drift. However, numerous exposures of the Pierre are present, generally in road cuts and river valleys of the southwestern and northeastern corners of the State. More scattered outcrops occur along Beaver Creek and the Missouri River …

An Explication Of Some Philosophical Aspects Of The Thought Of Orson Pratt, Joseph Willard Tingey
An Explication Of Some Philosophical Aspects Of The Thought Of Orson Pratt, Joseph Willard Tingey
Theses and Dissertations
No formalized philosophical system has officially represented the Church of Jesus Christ of Latter-day Saints to this time. Some claim there is need for one while others believe that none is forthcoming or necessary. Let the question be argued elsewhere. It is to be observed that metaphysics, epistemology, ethics, aesthetics, and science are all essentially represented in mormonism and should at least be recognized in comparison with their kind.
The useful practices of various epistemologies were employed for verification purposes although authoritarianism dominated the acquisition of knowledge in the infant Church. This need not indicate that the submitting authority was …

Rhenium Catalysis I. Hydrogenation And Hydroformylation Using Rhenium Carbonyl Compounds ; Ii. Hydrogenation Using Catalysts Obtained From The Reduction Of Perrhenates With Metals In Aqueous Solution, Terry G. Selin
Theses and Dissertations
The purpose of this work was to investigate the catalytic activity in both hydrogenation and hydroformylation reactions of rhenium preparations which have not been previously characterized. Rhenium pentacarbonyl was prepared in good yield from rhenium heptoxide and carbon monoxide. The optimum conditions for preparation were 25 hours per gram of dry rhenium heptoxide at 250° under 3000 psig. (initial) of carbon monoxide. Rhenium chloropentacarbonyl was prepared in 62% yield from potassium chlororhenite and carbon monoxide at high temperatures and pressures. The iodopentacarbonyl was prepared in 29% yield from potassium perrhenate, methyl iodide, and carbon monoxide. The preparation of rhenium hydrocarbonyl …
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
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 …
Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson
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
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
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, …

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