The Determination Of Thiamin And Its Derivatives In Brain Tissue Of Control, Thiamin-Deficient, Oxythiamin- And Pyrithiamin-Treated Rats, David S. Murdock

Theses and Dissertations

The determination of total thiamin, free thiamin, thiamin di phosphate (TDP) plus thiamin triphosphate (TTP), and total α- hydroxyethylthiamin (HET) levels in rat brain in control, deficient, oxythiamin- (OTH) and pyrithiamin- (PTH) treated rats was accomplished. It was found that the TDP + TTP/thiamin ratio observed in the thiamin-deficient, OTH- and PTH-treated rats was constant and did not differ from the ratio observed in the control rat brains. The brain levels of TDP + TTP decreased to 39% and 12% of the control thiamin levels in deficient and PTH-treated rats respectively. The brain HET and TDP + TTP levels of …

Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence

Theses and Dissertations

Purified Bacillus subtilis DNA taken up by one-day-old barley embryos and permanently fixed within the barley cell is shown to have maintained its biological activity in B. subtilis transformation. Cesuim chloride density gradient centrifugation of DNA isolated from the roots of barley embryos after the uptake and incorporation of radioactive, bromouracil-labelled B. subtilis DNA indicates the presence of the bacterial DNA in several discreet bands of well-defined density, whose density is changed by sonication. These preliminary findings concerning the fate of bacterial DNA taken up by barley roots are discussed in terms of the recombination model of Ledoux and Huart …

The Purification And Characterization Of Cytochrome B₅ From Porcine Kidney, M. Dean Klingler

Theses and Dissertations

A soluble form of cytochrome b_5, with a 413/280 nm ratio of nearly unity, has been isolated and purified from porcine kidney using fractional precipitation, ion exchange resins, and gel filtration procedures. The cytochrome b_5 shows heat stability up to 50° and is stable in the pH range 6.0 to 8.5. The oxidized protein exhibits an absorption maximum at 413 nm, while the reduced form shows three peaks: 423, 526, 556 nm. Molecular weight determinations have given variable results, suggesting the possibility of a polymer composed of four and eight units of a 13,500 molecular weight protomer. This study has …

|Ni.|Pa Calorimetric Study Of The Heat Of Ionization Of Water At 10 And 40°C, And,|Nii.|Pa Calorimetric Determination Of The Heat Of Reaction Of Tris (Hydroxymethyl) Aminomethane (Tham) With Hydrochloric Acid In Aqueous Solution At 10, 25, And 40°C, Griffith Lyn Kimball

Theses and Dissertations

The heat of neutralization, ΔH_-N, of perchloric acid with sodium hydroxide has been determined at 10 and 40° in a low ionic strength, μ, region using a nonisothermal, constant-temperature-environment solution calorimeter. Correction of the data to infinite dilution by extrapolation of a plot of ΔH_-N vs μ^0.5 gives values at zero ionic strength for the heat of ionization of water of 14.216 and 12.695 kcal/mole, respectively, at 10 and 40° . The data are correlated with those of earlier workers to give an equation allowing the calculation of the heat of ionization of water at zero ionic strength over the …

⁷Li(D,P)⁸Li Excitation Function :|Be[Subscript D] = 0.623 Mev To 1.968 Mev, Albert E. Schilling

Theses and Dissertations

In this study the excitation function for the ^7Li(d,p)^8Li reaction is determined at incident deuteron energies ranging from 0.623MeV to 1.968MeV by counting the delayed alpha-particles as a result of the ^8Li beta decay. This excitation function reveals resonances at 0.777±0.012MeV and 1.031±0.015MeV with cross sections of 202±9mb and 188±8mb respectively. The uncertainty in the cross section values was due to three independent sources of error within this experiment, the solid angle, the ^8Li half-life, and the target (LiF) thickness. The uncertainty in the energy values was determined from an energy calibration of the accelerator used in this study. Resonances …

Transient Convective Heat Transfer In Closed Containers During And After Gas Injection, Jennings Donell Means

Theses and Dissertations

This dissertation presents experimental data correlations for the spatially - averaged convective heat transfer coefficient for thin walled closed containers during and after gas injection. The different modes of heat transfer were identified, and correlations were made for each. Correlations are presented for the injection period, post-top injection, post-bottom injection, post- tangential, post-radial injection, and post-ejection heat transfer for various tank geometries. Of special significance are the very high heat transfer rates that were shown to be present in some cases immediately after injection. Heat transfer rates were shown to be, for a short period, up to almost two orders …

The Design And Analysis Of An Electro-Pneumatic Signal Converter, Richard K. Thornton

Theses and Dissertations

In the field of process control it is desirable to study dynamic characteristics such as frequency response and distortion when determining just how equipment is to be controlled. Pneumatic controllers, transmitters, control valves, etc., all have dynamic behaviors which can be expressed mathematically as transfer functions. Each component plays an important role in determining the entire system behavior. Frequency response is one technique used in developing a component’s transfer function. By driving a device with a sinusoidal signal of fixed amplitude and frequency the output amplitude and phase shift are measured and compared with that of the input. Varying the …

Reactions Of N₂F₄ And Sf₆ With H₂ Induced By Co₂ Laser Pulses And By Electrical Discharge, John Leslie Lyman

Theses and Dissertations

A high power pulsed CO_2 laser was used to induce reactions in gas mixtures containing either N_2F_4 or SF_6. The rate of laser induced dissociation of N_2F_4 to NF_2 was as much as 1000 times faster than the thermal rate, and the rate law was of lower order than the thermal, bimolecular rate law. Explosion threshold and induction time data were obtained for butene stabilized mixtures of N_2F_4 and H_2. HF laser gain was observed during the first few microseconds of CO_2 laser pulse, but it was strongly quenched by the explosion. The laser driven reaction of SF_6 with H_2 …

Finite Conductance Element Method Of Conduction Heat Transfer, E. Clark Lemmon

Theses and Dissertations

One of the basic goals in engineering is to formulate models which will provide a means for analytically predicting observed phenomenon. For some time, the partial differential equations describing the steady state and transient conduction of heat within a solid have been available. However, the straight forward use of these equations is often restricted due to the surface geometry of the solid. If the surface geometry is at all irregular, exact solutions will in general not exist. In that case, a solution is sought by some approximate numerical technique. The two techniques most often used are the finite difference method …

An Aerodynamic Investigation Of The Causes Of Overhead Electrical Transmission Line Gallop, Eric Nathan Skousen

Theses and Dissertations

Overhead electrical transmission lines vibrate due to the action of a prevailing wind. These cable vibrations can be classified into two categories— high-frequency and low-frequency. The high-frequency vibrations, "aeolian" vibrations or "singing wires," is a low-amplitude phenomenon. It has been largely controlled with the use of various mechanical dampers [l, 2],

A Proposed Mechanism Of Action For In Vitro Excystation Of Two Species Of Coccidia, William Ronald Jolley

Theses and Dissertations

Excystation of coccidian oocysts is accomplished in vitro by altering wall permeability with CO2 and a reducing agent, then activating the enclosed sporozoites with a solution of trypsin and bile. Elucidation of the mechanism of action of the CO2-reducing agent treatment was the basic intent of this study. Oocysts of Eimeria stiedae (rabbit) and E. tenella (chicken) were tested for the presence of an excystation-associated enzyme by incubating sporulated oocysts in fluids extracted from variously treated oocysts, and by carbon-14 labelling; the effect of CO2 -reducing agent treatment on oocyst walls was investigated by titration with acid or base for …

A History Of The Involvement Of The Church Of Jesus Christ Of Latter-Day Saints In The Tanning Industry In Utah From 1847 To 1973, Paul Edwards Damron

Theses and Dissertations

This thesis reports the extent of the tanning industry in Utah from 1847 to 1973 and explains the relationship of The Church of Jesus Christ of Latter-day Saints with this industry.

The tanning industry was essential to the survival of the pioneer communities in Utah until the coming of the railroad in 1869. Two important factors affecting this industry were external competition and Church support. In fact, the industry survived eastern competition because it was Church-supported. However, all Church support ended in the early 1900's, and except for a few businesses which soon ceased operation, the tanning industry in Utah …

The Effect Of Aflatoxin B1 On Growth Rate And Iron Metabolism In Juvenile Mongolian Gerbils (Meriones Unguiculatus), William Stanley Hastings Jr.

Theses and Dissertations

The metabolic secretions from Aspergillus flavus, aflatoxins. are often found as contaminants of agricultural products used for human and animal consumption. Aflatoxin B1 is the most toxic and carcinogenic of the aflatoxins. A reduction in weight gain has been observed when juvenile animals are fed aflatoxin B1 over an extended period of time. This reduction in weight gain may possibly result from an anemic condition induced by an alteration of iron absorption and/or distribution. The effect of chronic sublethal levels of this hepatocarcinogen on weight gain and the uptake and distribution of 59Fe++ were studied in this investigation.

An experimental …

The Correlation Program Of The Church Of Jesus Christ Of Latter-Day Saints During The Twentieth Century, Jerry Rose

Theses and Dissertations

Within recent years the priesthood correlation program of the Church of Jesus Christ of Latter-day Saints has received significant emphasis from the leaders of the Church, so much so that it has been regarded by some as a new forceful program for the perfecting of the Saints. However, research reveals that the principles of priesthood correlation have always been a part of the restored Church.
The purpose of this thesis is to write a history of the correlation program of the Church of Jesus Christ of Latter-day Saints with particular emphasis on the period 1908 to February 1972.

Zion's Camp, Wilburn D. Talbot

Theses and Dissertations

In 1831, Jackson County, Missouri, was designated as a place of refuge for the members of the Church of Jesus Christ of Latter-day Saints. Attempts to establish permanent residence in their Zion ended in bloodshed and violence. An army was raised to go to the aid of those cast out of their homes. This thesis pays particular attention to the recruiting of the army and the gathering of money and provisions, the trek to Missouri, and the interaction of those promoting and opposing the camp.

The trek from Kirtland, Ohio, to Jackson County, Missouri, revealed frustrations, hardships, strengths, weaknesses, and …

The Des Moines Rapids: A History Of Its Adverse Effects On Mississippi River Traffic And Its Use As A Source Of Water Power To 1860, Donald L. Enders

Theses and Dissertations

During the 19th Century, the Mississippi River was the chief commercial highway in the United States. But for two impediments, the Upper and Lower (Des Moines) Rapids, its entire course of 2400 miles would have offered an untroubled thoroughfare to watercraft.

The federal government, as well as private concerns, attempted throughout the better part of that century to alleviate the river of its barriers and to develop its rapids as a source of power. Those attempts were disappointingly unsuccessful, however, and not until the advent of the 20th Century, when the nation had matured both economically and technologically, was the …

Alexander William Doniphan, The Forgotten Man From Missouri, Gregory P. Maynard

Theses and Dissertations

Few men on the Missouri frontier in the nineteenth century exemplified the quality of character, integrity, as well as did Alexander William Doniphan. Whether in his capacity as a lawyer, soldier, legislator or friend, he remained steadfast to his beliefs and principles, though often in the minority.
Several books have been written about Doniphan's military experiences during the Mexican War. But surprisingly this is the only part of his life which so far has been reported in great detail. The other aspects of his career have been treated only in a sketchy manner. It is therefore the purpose of this …

Possible Lexical Hebraisms In The Book Of Mormon: (Words Of Mormon - Moroni), Melvin Deloy Pack

Theses and Dissertations

This thesis has been a study of possible lexical Hebraisms occurring in the Book of Mormon in the sections entitled "The Words of Mormon" through "Moroni." A Hebraism was defined as any word or phrase which appeared to be a literal rendering of a Hebrew lexicographic mode of speech, in that the English had a usage or connotation which was not normal; whereas, if translated literally into Hebrew it would represent standard usage.

Nearly two hundred such items were found, some one hundred twenty of which were discussed in the body of the thesis. Of these, nouns contributed over sixty …

J. Bracken Lee And Utah Public Education, Elwin Lee Reynolds

Theses and Dissertations

The purpose of this thesis is to examine the two gubernatorial terms of J. Bracken Lee, Governor of Utah 1948-1956, and the effect he had on education during these years. Lee has been accused by his detractors of being opposed to education. He has been defended by his supporters as being a friend whose only desire was to have education operated on a sound fiscal basis. During his two terms as governor he was almost constantly involved in some dispute with the education people in the state and was frequently on the defensive against anti-education charges.
