Drag Forces On Magnetically Accelerated Particles, Darrell Winterton Walker

Theses and Dissertations

The object of this investigation was to determine the effect of acceleration on the drag of spheres as it differs from the steady state case. Steady state drag applies to the force acting on a single sphere moving at constant velocity through an infinite, continuous, incompressible, turbulence free fluid. Extensive experimentation has quite thoroughly documented the steady state drag characteristics of spheres. A dimensionless parameter associated with the drag force is sometimes used to correlate drag characteristics.

At the end of the eight week training period, they participated in unrelated …

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 …

Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes

Theses and Dissertations

The atomization of a liquid by an air stream has been an item of much concern in the past, and there have been numerous experimental studies of the process made in an effort to correlate liquid and air- stream physical properties into a general model which will predict the degree of and the time required for atomization for a given physical situation. The breakup of liquid drops, a major portion of the atomization process, finds application in the field of meteorology, where the formation, breakup, and shape of raindrops is an item of much concern; in the field of internal …

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 …

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 …
