Jurassic Stratigraphy Of The Southern Two-Thirds Of North Dakota, Richard A. Salisbury

Theses and Dissertations

Jurassic rocks in the southern two-thirds of North Dakota consist mainly of limestone, shale, anhydrite, and salt of the Piper Formation; shaly limestone, calcareous and non-calcareous shales of the Rierden Formation; shale and sandstone of the Swift Formation; and, at the top, non-marine shale and local sandstones of the Morrison Formation.

The units generally are conformable in the deep part of the Williston Basin, and are unconformable near the edge of the basin in eastern North Dakota. The Poe Member of the Piper Formation, however, unconformably overlies the Spearfish Formation in the western part of North Dakota where Dunham salt …

The Synthesis Of 4-Spiro-2-Aryloxazolines Of Potential Pharmacological Interest, Paul Waddell Collins

Theses and Dissertations

Numerous and diverse physiological actions are found among 2-oxazoline compounds. No reports of the synthesis or biological testing of 4-spiro-2-aryl-2-oxazolines were found in the literature. On the basis of the known pharmacological activities of certain aza- and diazaspirans, it was felt that 4-spiro-2-aryl-2-oxazolines should possess medicinal activity. In particular, it was reasoned that the combination in a bicyclic spiro structure of the 2-oxazoline ring with rings systems commonly found in synthetic antitussive compounds might result in active antitussive agents.

The aim of this research was the synthesis of a series· of 2-aryl-2-oxazoline-4-spirocyclopentanes and a series of 1'-methyl-2-aryl-2-oxazoline-4-spiro-4’-piperidines. Six members were …

Surficial Geology Of The Southern Half Of Griggs County, North Dakota, James C. Merritt

Theses and Dissertations

The southern half of Griggs County, in east-central North Dakota, lies entirely within the Young Drift section of the Central Lowlands physiographic province and is characterized by its undulating surface and nonintegrated drainage. The Kensel, Cooperstown, and Luverne phase of a Late Wisconsinan glaciation are largely responsible for the present appearance of the surface. The tills deposited during glacial stillstands cannot yet be differentiated by texture or X-ray diffreaction analyses, but the average shale pebble content of Kensel till is 16% higher than Cooperstown till.

Synthesis of Pleistocene history is based on the distribution of lithostratigraphic units and glacial geomorphic …

Surficial Geology Of Northern Griggs County, North Dakota, Laverne C. Rude

Theses and Dissertations

Griggs County, situated in the Western Lake section of the Central Lowland province, covers an area of 720 square miles in east-central North Dakota. The surface of the county is mantled with three, or possibly four Pleistocene drift sheets, separated by outwash deposits. These drift sheets lie unconformably on the Cretaceous Pierre Shale which is exposed in the Sheyenne River valley and the Binford Hills. Because the drift sheets have similar lithologic and physical characteristics, and are all late Wisconsin in age, they fulfill the requirements for a lithostratigraphic unit and are being considered for designation as part of the …

The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams

Theses and Dissertations

The level of gamma-aminobutyric acid in the brains of white rats suffering from thiamine deficiency symptoms resulting from pyrithiamine or oxythiamine antagonism of thiamine or from thiamine deprivation was measured. The level of this amino acid was 17.5% lower in the brains of pyrithiamine-treated rats and 20.0% lower in the brains of thiamine-deprived rats than in the control rats. Daily injections of ten times the required amounts of vitamin B6 in rats treated with pyrithiamine or oxythiamine or by thiamine deprivation had no effect on the level of brain gamma-aminobutyric acid or on the psiological behavior of these rats. The …

Thermodynamics Of Proton Ionization In Aqueous Solution I. A Precision Thermometric Titration Calorimeter ; Ii. Entropy Titration : A Calorimetric Method For Equilibrium Constant Determinations ; Iii. H And S Values For Carboxylic Acid Proton Ionization At 25c ; Iv. Site Of Proton Ionization From Adenosine, Lee D. Hansen

Theses and Dissertations

The design, construction, and calibration of a precision thermometric titration calorimeter is described. This calorimeter was tested by determining the enthalpy change for ionization of water. The result, 13.34 ±0.03 kcal/mole (standard deviation), is in exact agreement with the best literature values. This standard deviation indicates that, using this calorimeter, ΔH values can be determined with an accuracy of ±0.0.5 kcal/mole. A calorimetric procedure has been developed for the, simultaneous determination of the equilibrium constant, the enthalpy change, and the entropy change for a chemical reaction from a single titration (Entropy Titration). This procedure has been tested by determining pK, …

Studies Of Rat Brain Thiamine Pyrophosphokinase, Lavell Rolfson Johnson

Theses and Dissertations

The enzyme ATP:thiamine pyrophosphotransferase (thiamine pyrophosphokinaseJ was purified from acetone powders which were prepared from rat brains up to the chromatography on alumina C_γ step by a modified procedure that Mano (Y. Mano, J. Biochem., 42, 283 (1960)] developed for the purification of the rat liver thiamine pyrophosphokinase. The enzyme was purified 12 fold over that in the original extract of the acetone powder. A spectrophotometric assay for the brain thiamine pyrophosphokinase was developed utilizing brewer's yeast apotransketolase. The transketolase assay was able to detect less than 10^-11 moles of thiamine diphosphate, which was synthesized by the kinase, in the …

Properties Of Chlorophyll Derivatives Bonded To Polymers, Richard Grant Jensen

Theses and Dissertations

Two types of water-soluble complexes of chlorophyll a with organic polymers have been investigated: chlorophyll a coordinately bonded to poly 4-vinylpyridine and a chlorophyll derivative, Mg-chlorin e_6 phytyl methyl ester, covalently bonded to GANTREZ AN (poly (methyl vinyl ether/maleic anhydride) ). The first complex was observed upon dissolving chlorophyll a and poly 4-vinylpyridine in aqueous ethanol solutions. The Mg-chlorin e_6 diester-GANTREZ AN complex (chlorophyll a/polymer) was made by aminolysing the chlorophyll ring V with 1, 6-hexanediamine to give an intermediate product, Mg-chlorin e_6 -6-N-(6' -aminohexyl) carboxamide, phytyl methyl ester. This was attached to GANTREZ AN by linkage of the 6'-amine …

Thermodynamics Of Charge Transfer Complexes, Reed J. Jensen

Theses and Dissertations

Charge transfer complexes were studied spectrophotometrically in the liquid state by a modified Benesi-Hildabrand method. TiCl_4 - Benzene and TiCl_4 - diphenyl ether solutions were found to form contact charge transfer complexes, that is complexes with very weak and non-directional interactions. The systems TiCl_4 - anisole and TiCl_4 - diethyl ether form complexes of the types AD and AD_2 where A stands for TiCl_4 and D stand s for the organic donor. The formation constants for the complexes were, for the TiCl_4 - anisole, K_1 = 0.077, K_2 = 0.01; and TiCl_4 - diethyl ether, K_1= 3.0, K_2 = 1.0. …

A Thermodynamic Study Of (1) Ligand Replacement Reactions And (2) The Interaction Of Hgcl[Subscript 2](Aq) With Hydroxide Ion, Ethylenediamine, Glycinate Ion, And Methylamine, Jerry Alvin Partridge

Theses and Dissertations

A method is reported for determining the species formed in solution by ligand replacement reactions. Reactions in dilute aqueous solution were studied in which the Cl^- on HgCl_2(aq) was replaced by hydroxide ion, ethylenediamine, glycinate ion, and methylamine. The species formed by the replacement reactions were established through computer analysis of pH titration data. Various reaction sequences were proposed for each system and log K values were calculated for each sequence. The selection of the correct reaction sequence for each system was based on the premise that only when the correct sequence is proposed will consistent log K values be …

Hydrogenation Of 4-Methylcinnoline, William E. Maycock

Theses and Dissertations

The rapid expansion of knowledge of cinnoline chemistry since 1941 has not included the hydrocinnolines. Not one catalytic hydrogenation of a fully aromatic cinnoline had been reported. This thesis is an effort to enlarge knowledge of this particular area of cinnoline chemistry. The work is a natural outgrowth of that done at Brigham Young University on decahydroquinoxaline, both the cis- and trans- isomers having been prepared and characterized. 4-Methylcinnoline, prepared by the method of Jacobs, et.al., was hydrogenated in neutral and acidic ethanolic solutions at 2000-3000 psig. hydrogen pressure and 100-266°. The catalysts used were 5% palladium on alumina, ruthenium …

Glacial Geology Of The North Half Of Barnes County, North Dakota, Douglas A. Block

Theses and Dissertations

The geomorphology and glacial geology of the north half of Barnes County in east central North Dakota is described and interpreted. The area comprised a portion of the Western Lake section of the Central Lowland province and was informally designated the Middle Sheyenne River area without defining its boundaries. Four physiographic subdivisions in the Middle Sheyenne River area were assigned: 1. The Kensal Glacial Plain subdivision that embraces land between the Sheyenne River and the west county boundary. 2. The Sheyenne River Valley subdivision. 3. The Glacial-Lake Plains subdivision that consists of three separate but genetically related areas of lacustrine …

Relationship Of The Turtle, Forest, And Park Rivers To The History Of Glacial Lake Agassiz, Samuel S. Harrison

Theses and Dissertations

The thesis here abstracted was written under the direction of Wilson M. Laird and approved by John R. Reid and Alan M. Cvancara as members of the examining committee, of which Dr. Laird was Chainnan.

During the summer of 1964 a study of the Turtle, Forest, and Park river valleys was undertaken to find evidence of former changes in river regimen. The regimen of rivers once draining into glacial Lake Agassiz was probably affected by changes in base level associated with fluctuations of that lake. The Turtle, Forest, and Park rivers, which presently flow eastward across the bed of Lake …

Metabolism Of Thiamine And The Effect Of Some Antagonists, Russel M. Bender

Theses and Dissertations

To investigate the possibility that thiamine has more than one vital role in the mammalian system, it was decided to use the antagonists pyrithiamine and oxythiamine, and to utilize carbon-14 labeled compounds to more effectively study the vitamin and the above-named antagonists. To make it more effective, we felt that perhaps differences between the localization of oxythiamine and pyrithiamine could be detected in the brain. We also considered and tested the possibility that either or both of the antagonists would alter the localization of thiamine. Essentially, two procedures were used in this study. One was a counting method and the …

Evaluation Of Methods Used In The Determination Of Stability Constants Of The Thallium (Iii)-Chloride System At Twenty-Five Degrees, Nelson Kent Dalley

Theses and Dissertations

The difficulties encountered in the determination of equilibrium constants in systems with small, not directly rneasureable free ligand concentrations are discussed. These difficulties are illustrated using the determination of the formation constants of the Tl(III)-Cl- system as a specific example. Four methods are used and evaluated in this study. They are (1) the corresponding solutions method, (2) the method of Fronaeus, (3) the solubility of AgCl in Tl(III) solution method and (4) the method of Hugus. A discussion and derivation of each of these methods is given. The first three methods given and free ligand concentration data from which formation …

Type sections for all three members are herein established. Isopachous maps and stratigraphic cross sections have been prepared to delireate the thickness and distribution of each of the units …

Glacial Geology Of Western Wells County, North Dakota, George A. Faigle

Theses and Dissertations

The landforms of western Wells County were formed during late Wisconsinan glacial activity. Because of the relatively dry climate they have been modified only slightly by post-glacial erosion and mass wasting.

The southern one-third of the area is characterized by randomly-oriented mounds of till or dead-ice moraine. The dead-ice moraine originated when a large mass of stagnant ice ablated after typical glacial depositional features had formed on its drift-covered surface. Complete ablation of the ice resulted in the collapse of the previously formed features.

The remaining two-thirds of the area is characterized by and moraine, ground moraine, outwash, and meltwater …

The Geology Of Eastern Wells County, North Dakota, Ronald J. Kresl

Theses and Dissertations

Late Wisconsinan (Pleistocene) glaciation was responsible for the varied landforms of eastern Wells County. The Burnstad-Streeter phase advanced from the north-northeast about 10,000 to 12,000 years ago and was obstructed by the elevated Missouri Coteau which caused basal shearing and subsequent movement of subglacial drift into the ice. As this ice stagnated, the resultant drift cover impeded ablation and insulated the waters of superglacial lakes present on the surface of the Coteau at that time. Abundant Pleistocene fossils have been found in the sediments of these former lakes. Upon complete ablation, characteristic dead-ice features resulted on the surface of the …

The Glacial Geology Of Eastern Sheridan County, North Dakota, Thomas C. Gustavson

Theses and Dissertations

During late Pleistocene time two ice advances affected parts of eastern Sheridan County, North Dakota. The first advance deposited the Burnstad, Streeter and Grace City drifts, and covered the whole county. The second advance deposited the Martin drift and occupied only the northern quarter of the county.

The Streeter drift, characterize by dead-ice landforms and nonintegrated drainage, is separated from the Burnstad drift by a large partly collapsed outwash plain on the distal side of a pronounced ground moraine and poorly integrated drainage, is separated from the Streeter drift by the Lincoln Valley and moraine and the Missouri Coteau escarpment. …

The Physical Limnology And Sedimentology Of Miller Lake, Martin River Glacier, South-Central Alaska, Edward Callender

Theses and Dissertations

Miller Lake is an ice-walled lake located on the terminus of the Martin River Glacier, south-central Alaska. It has an area of 1.36 km² and a mean depth of 25 meters. The lake basin was formed by the coalescence of several ice sinkholes and is characterized by extremely uneven bottom topography.

Analysis of detailed thermal data obtained during the summer of 1963 indicates that the lake is never permanently thermally stratified but does develop some stratification during periods of warm, calm weather. This stratification is easily destroyed by stormy weather. Miller Lake is classified as a subpolar lake due …

Lower Paleozoic Chitinozoans And Scolecodents From North Dakota, Douglass H. Morgan

Theses and Dissertations

Chips from cores of the Red River and Stony Mountain Formations of Ordovician age and the Dawson Bay Formation of Devonian age in North Dakota were taken at three-foot intervals, dissolved in acid, and the residue examined for insoluble, pseudochitinous microfossils. Chitinozoa, an extinct order of rhizopod protozoans, were found in abundance along with lesser numbers of scolecodonts, the mouth parts of polychaete worms. Because the study was restricted to the core available at the North Dakota Geological Survey, which rarely included complete sections of the formations, a complete picture of the distribution of these forms must await the more …

I. Preparation And Properties Of Alkyl And Aryl Substituted Thioquinazolines And Sulfoxides ; Ii. An Investigation Of The Quinazoline 3-Oxide--1,4-Benzodiazepine 4-Oxide Rearrangement, Marvin C. J. Kuchar

Theses and Dissertations

I. The quinazolines, a branch of the benzodiazine class of aromatic nitrogen hetercycles, do not occur to any great extent in naturally occurring compounds. The discovery of the antimalarial febrifugine and its structure elucidation led to the preparation and investigation of a host of new quinazolines in the search for new and more effective antimalarials. Most of the present body of information governing the quinazolines arose out of these synthetic studies. The present study has been accomplished with a four-fold purpose in mind: (1) to investigate the susceptibility of chloroquinazolines to nucleophilic displacement reactions by thiols or their salts, (2) …

Thermodynamics Of I) Metal Cyanide Coordination, Ii) Water Formation, And Iii) Metal Halide Coordination, John Dewey Hale

Theses and Dissertations

ΔH values for the formation of Ni(CN)4(aq)= have been determined calorimetrically at 25° using a simple calorimeter and a thermometric titration procedure at high and low ionic strengths, respectively. Extrapolation of these ΔH values to infinite dilution resulted in a ΔH° value of -42.7 kcal./mole. Combination of ΔH° and ΔF° values gives a ΔS° value of -5.5 e.u. for Ni(CN)4(aq)= formation. A value of +70 e.u. is calculated for the ionic entropy of Ni(CN)4(aq)=. A preliminary investigation of the Zn(CN)4(aq)= system indicated the existence of zinc cyanide complexes other than Zn(CN)4= and allowed calculation of an approximate ΔH° value of …

Directive Effects In The Sulfonation Of Toluene ; Synthesis And Attempted Rearrangement Of Some Anilinoketones ; The Kinetics And Mechanism Of The Addition Of Bromine To Cyclohexene In Dichloromethane. Solution, John Joseph Duvall

Theses and Dissertations

The pure sodium salts of the toluenesulfonic acids were prepared by one of two ways. Both methods started with diazotization of the toluidine. In the first method, the diazonium solution was treated with sulfur dioxide and copper powder, and the resulting sulfinic acid was oxidized to the sulfonic acid with potassium permanganate. In the second method, the diazonium solution was treated with cuprous chloride and sulfur dioxide to give the sulfonyl chloride which was hydrolyzed to the sulfonate. Toluene was sulfonated by SO3 (enriched with S-35) in refluxing SO2 solution. The isotope dilution technique was used to determine the isomer …

The Structural And Stratigraphic Relationships In The Paleozoic Rocks Of Eastern North Dakota, Frederick V. Ballard

Theses and Dissertations

The thickness and areal extent of the commonly defined Paleozoic rock units in eastern North Dakota has been determined by a study of mechanical well logs. Isopachous wops of these units reveal several positive areas which persisted and influenced sedimentation and unit thickness throughout most of the Paleozoic Era. Precambrian topographic highs of either erosional or structural origin produced those influences in early Paleozoic time, whereas later effects resulted from periodic structural rejuvenation of the original highs. The activity of those highs appears to be related to the location of the basin depocenter. The most prominent highs were in Cavalier, …
