The Role Of Thiamine Pyrophosphate In Regulating The Level Of Gamma-Aminobutyric Acid In The Central Nervous System, Bryant L. Adams Aug 1965

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 …

Heat Transfer In Shock Boundary Layer Interaction Regions, Rex W. Shumway Aug 1965

Heat Transfer In Shock Boundary Layer Interaction Regions, Rex W. Shumway

Theses and Dissertations

The interest in aerodynamic heating problems has been increasing rapidly in the last decade. This interest is no longer concentrated on the heating of simple shapes for which adequate heat transfer theory has been developed« Because of the increasing Mach number ranges of aircraft, the need for information on the aerodynamic heating of various components has become imperative. Only when the magnitude of the problem has been exposed can the design for reducing the severity of local heating be optimized. Definition of these problems is of interest, not only because of the flow phenomena, but because of possible design limitations …

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 Aug 1965

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 …

The Investigation And Design Of A Powered, Single-Man Parawing Aircraft, Calvin J. Merrell Aug 1965

The Investigation And Design Of A Powered, Single-Man Parawing Aircraft, Calvin J. Merrell

Theses and Dissertations

During the last few years there has been an increasing interest in a high-lift wing configuration known as the flex-wing, or parawing. The parawing consists basically of a flexible membrane such as cloth, attached to two leading edges (or booms) and a keel as shown in Figure 1. At angles of attack (��) greater than the billowing angle (��). the air impinges on the under side of the membrane and forces it into a double-arch shape at each cross-section. When straight leading edges are used, each arch approximates the shape of a conical section. A cylindrical section is obtained by …

Turbulent Flow In The Entry Region, Chin-Hsiu Li Aug 1965

Turbulent Flow In The Entry Region, Chin-Hsiu Li

Theses and Dissertations

When entering into the subject of turbulent flow, it is essential to understand that the kind of flow with which we deal belongs to a particular class known as shear flow. These types of flow comprise flow fields in which relative velocities have been induced by shear stresses rather than by the action of pressure forces. In pipe flow, when the fluid enters through the well-rounded bell from a reservoir or from the calm open air, a uniform velocity distribution occurs at the pipe entrance. Immediately down stream from the entrance of the pipe, the flow is structured with a …

A Microscopic Study Of An Early Pennsylvanian Flora From The Manning Canyon Shale, Utah, Max W. Blaylock Aug 1965

A Microscopic Study Of An Early Pennsylvanian Flora From The Manning Canyon Shale, Utah, Max W. Blaylock

Theses and Dissertations

The Manning Canyon Shale on the eastern slope of Lake Mountain in Utah County, Utah contains an Early Pennsylvanian flora within its upper shales. Many of these fossils appear to be new species. A microscopic study of the tissue remains can be of value in the further classification of these fossils. Selected fossils were macerated in hydrofluoric acid, and the residues were examined microscopically for tissue remains. Objects identified as fossil tissue remains were found in twenty five of the forty-eight specimens examined. Fibers, fiber tracheids, tracheids, and spores were isolated from fossils identified as Calamites. The spores were possibly …

The Americanization Of Raetic ( Romanish, German, Italian Family Names From The Canton Grisons, Switzerland Jul 1965

The Americanization Of Raetic ( Romanish, German, Italian Family Names From The Canton Grisons, Switzerland

Swiss American Historical Society Newsletter

The Secretary of the SAHS, Dr. Augustin Maissen, has sent us a copy of " Studia Raetoromanica I", Ediziums Della Revista Retoromontscha. 1965 (Editor: Alfons Maissen, Chur). It consists of a study by Augustin Maissen on "L' Americanisaziun dils nums de schlatteina romontschs e grischuns" with an Abstract in English (19) pages. It is astonishing how many Bundner names, some of them extinct in Grabunden, have been preserved in the U.S., either in the original or in a somewhat anglicized form. There are even Romansh sepulchral inscriptions, e.g. at Badus (Romansh geographic name!) in South Dakota.

An English Translation Of J.R. Von Salis' Standard Work On Rilke Switzerland, L. B. Jul 1965

An English Translation Of J.R. Von Salis' Standard Work On Rilke Switzerland, L. B.

Swiss American Historical Society Newsletter

Among the many publications on the poet Rainer Maria Rilke the book by the Swiss Professor of History Dr. Jean Rodolphe von Salis, until recently President of the Foundation Pro Helvetia, excels by its tactful and sober approach to a delicate subject which all too often has been misused by panegyrists full of loud enthusiasm, but rather bare of substance. When Rilke arrived in Switzerland in 1919, von Salis was nearly eighteen years old and twenty five when Rilke died at Territet in 1926. Von Salis knew Rilke as a guest in his family, but more and more also in …

The Poetry Of Matthew Arnold: A Study In Versification, Douglas A. Mathewson Jul 1965

The Poetry Of Matthew Arnold: A Study In Versification, Douglas A. Mathewson

Theses and Dissertations

Despite the great number of published works that deal with English prosody or the more restricted subject of versification, there is a noticeable scarcity of studies that describe the practices of individual poets. One of the more apparent reasons for the meager number of versification studies is the instability of the basic criteria by which a poem is examined. Prosodists quite simply find it difficult to establish concrete principles of scansion that are acceptable to all other prosodists. Without going into discussion of the various schools of thought on metrical structure, suffice it to say that there are conflicting opinions …

Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes Jul 1965

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 …

Residual Stresses And The Bauschinger Effect, Raymond M. Huebner Jun 1965

Residual Stresses And The Bauschinger Effect, Raymond M. Huebner

Theses and Dissertations

Within the last ten years there has been much interest in the field of elasto-plastic behavior of engineering materials. Hie recent popularity of the low-cost light-weight plastically designed structures has added a great deal of impetus to this interest. This thesis deals with one of the aspects of elasto-plastic behavior, namely, the distribution of the residual stresses in a simple member which has been plastically deformed in tension and/or compression,. In particular, an attempt has been made to relate these residual stresses to the well-known but little understood Bauschinger effect.

Residual Stress Distribution Changes During Dynamic Unidirectional Tensile Loading, Henry Swan Todd Jun 1965

Residual Stress Distribution Changes During Dynamic Unidirectional Tensile Loading, Henry Swan Todd

Theses and Dissertations

In recent years there has been much engineering effort channeled toward obtaining higher strength, lower weight and cost product designs. In pursuit of this goal some carefully designed and tested parts have catastrophically failed after a long history of repeated successful service, even though the load at the time of failure was no higher than the part had repeatedly carried previously. These mechanical failures are commonly classified as fatigue failures.

Tularemia And Deer Flies In The Environs Of Utah Lake, Utah, Kaye B. Cox May 1965

Tularemia And Deer Flies In The Environs Of Utah Lake, Utah, Kaye B. Cox

Theses and Dissertations

Deer flies have been implicated as mechanical veotors of tularemia in Utah. Although infected flies heretofore have not been tound in nature, there is little doubt of their importance in transmitting tularemia to man. Two species present in this area, Chrysops discalis Williston and Chrysops noctifer Osten Sacken, have been shown experimentally to transmit the disease. The presence of deer flies in the environs of Utah Lake where tularemia is endemic oftera a potential health threat to man, and the expanding human population and development ot recreational facilities adjacent to the lake inorease this potential. Despite the taot that deer …

Properties Of Chlorophyll Derivatives Bonded To Polymers, Richard Grant Jensen May 1965

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 May 1965

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. …

Religious Attitudes In The World Of Humphry Clinker, Byron Gassman Apr 1965

Religious Attitudes In The World Of Humphry Clinker, Byron Gassman

BYU Studies

Tobias Smollett's Expedition of Humphry Clinker provides a vivid and perceptive view of eighteenth-century Scotland and England. Written as a series of letters from a Welshman travelling through Scotland and Ireland, Humphry Clinker reveals Smollett's unease over the political and economic changes in English society. Smollett's religious commentary, although less central than his political commentary, is no less valuable. Smollett's satirical treatment of both the Anglican clergy and the Methodist movement gives modern readers a glimpse of a segment of religious thought in his time.

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 …

Europe's Contribution To American Civilization, Alfred Zehnder Apr 1965

Europe's Contribution To American Civilization, Alfred Zehnder

Swiss American Historical Society Newsletter

You have invited me to speak about Switzerland's contribution to American civilization. This is quite a task. I don't intend to give you today a complete study on this subject. You will see later why. Switzerland is not only a small country in the heart of Europe, but it is Europe. And Europe is Switzerland. It is impossible to determine exactly what part in the Swiss contribution is genuine Swiss, and what part is European. That is why I would like to invite you to try with me to discover the great ideas and the fact s which ought to …
