The Introduction Of Asian History Into Utah High Schools, Carol M. Hinckley
The Introduction Of Asian History Into Utah High Schools, Carol M. Hinckley
Theses and Dissertations
Asian history is increasingly recognized by experts as a necessary part of a high school student's world history experience. Asia is important for them to study because of its great intrinsic value and because of Asia's relationship with the United States in the future. To date, however, in Utah there are no separate Asian history courses being taught and few teachers include Asia as an important part of the world history course.
Schools in other parts of the nation have instituted practical Asian history courses and Utah can follow their example. Teachers should consider how much time can be devoted …

Rayleigh Hysteresis Shape: Its Relationship To Displacement Distance Of A Single Domain Wall In 50% Ni–Fe, R. C. Woodbury, M. R. Hunt
Rayleigh Hysteresis Shape: Its Relationship To Displacement Distance Of A Single Domain Wall In 50% Ni–Fe, R. C. Woodbury, M. R. Hunt
Faculty Publications
The need to measure the displacement distance of domain walls from equilibrium for very weak alternating fields (H ≪ coercive force) in bulk magnetic material has prompted a study of the possible use of the opening of the Rayleigh hysteresis loop to indicate the amount of wall displacement. This paper contains (1) a review of the theoretical relationship between hysteresis shape and the displacement distance of a domain wall, based upon defect-energy models of Rodbell and Bean, and Baldwin; and (2) an experimental approach which provides a measure of the wall displacements versus hysteresis shape for 50% Ni–Fe tape. Discrepancies …
Asymptotic Evaluation Of Wkb Matrix Elements. Ii. Use Of Langer's Uniform Asymptotic Wavefunctions, Wesley D. Smith, Russell T. Pack
Asymptotic Evaluation Of Wkb Matrix Elements. Ii. Use Of Langer's Uniform Asymptotic Wavefunctions, Wesley D. Smith, Russell T. Pack
Faculty Publications
An improvement in a previous procedure for the analytic asymptotic evaluation of integrals arising in the quantum-mechanical theory of inelastic molecular collisions is presented. The integrals are evaluated using Langer's uniform asymptotic wavefunctions and the higher-order saddle-point or steepest-descents method. It is found that the Langer functions give no better results than WKB functions, but the higher-order steepest-descents corrections produce a marked improvement. The result is a simple method for evaluating a large class of integrals with an error of 0.1%-2.1%.
Proposed Thermodynamic Pressure Scale For An Absolute High-Pressure Calibration, Daniel L. Decker, J. Dean Barnett
Proposed Thermodynamic Pressure Scale For An Absolute High-Pressure Calibration, Daniel L. Decker, J. Dean Barnett
Faculty Publications
The field of high pressure has developed rapidly over the past few years to a point where relatively sophisticated experiments are being attempted. In many experiments it is no longer sufficient to qualitatively estimate the pressure or to base conclusions on experimental results tied to an empirical pressure parameter. One desires to accurately know the pressure dependence of physical quantities related to a true thermodynamic scale.

The School Of The Prophets: Its Development And Influence In Utah Territory, John R. Patrick
The School Of The Prophets: Its Development And Influence In Utah Territory, John R. Patrick
Theses and Dissertations
Four separate and distinct Schools of the Prophets were organized by the Church of Jesus Christ of Latter-day Saints. Joseph Smith Jr. organized the first school in the spring of 1833, and it functioned periodically until 1837. Brigham Young organized the second school in December 1867, as a part of the University of the State of Deseret. It functioned until August of 1872 when Brigham Young disbanded it because members failed to adhere to its rules. Three months later he reorganized on a limited basis a third school in Salt Lake City. This school existed until the summer of 1874 …

Quasilattice Interpretation Of The Thermodynamic Properties Of Mixing Of Binary Alkali-Metal Systems, J. Bevan Ott, J. Rex Goates
Quasilattice Interpretation Of The Thermodynamic Properties Of Mixing Of Binary Alkali-Metal Systems, J. Bevan Ott, J. Rex Goates
Faculty Publications
Quasilattice theory was applied to heats of mixing in the six systems formed from the binary combinations of Na, K, Rb, and Cs. The alkali-metal systems are particularly well suited for a critical test of the quasi-crystalline assumption since the theoretical model for these systems is relatively simple and the thermodynamic data are fairly complex. Very good fits of the heat-of-mixing data were achieved by assuming that the larger atom in the binary system covered multiple sites on the quasilattice. The values of the empirically determined constants appear to fit the physical significance accorded to them by the quasilattice model. …

An Optimization Technique Applied To The Determination Of Orthotropic Material Properties Using Dynamic Response Test Data, Ronald L. Webster
An Optimization Technique Applied To The Determination Of Orthotropic Material Properties Using Dynamic Response Test Data, Ronald L. Webster
Theses and Dissertations
A knowledge of the behavior of a material under loading similar to expected service loading is required before that material can be used effectively in the design process. Without sufficient mechanical properties data, the design process degenerates to a time consuming and often costly "build, test and modify" type of program. Obviously, this trial and error approach leaves much to be desired.

A Computer Procedure For The Identification Of Beam, Spring, And Damping Parameters Of An N-Mass Model Using Transient Data, Lynn A. Christiansen
Theses and Dissertations
If, however, one could develop a model for a given physical system, that is a model which can be described in terms of lumped masses, springs beams, and dashpots and then identify the parameter simply by processing acceleration data such as that obtained from drop tests or shaker tests, the task of identification is greatly simplified.

A Thermodynamic Approach To The Study Of Phase Equilibria In The Sodium-Potassium Alloy System I. The Phase Diagram For Nak At Atmospheric Pressure ; Ii. High Pressure Phase Studies, Donald Ray Anderson
Theses and Dissertations
Ultra-pure reagents, platinum resistance thermometry and modern inert atmosphere glove box facilities have made possible a detailed examination of the NaK system at atmospheric pressure. A thermoanalytical study of solid-liquid phase equilibria in the NaK alloy system was conducted in the tetrahedral press to 55 kbars to investigate possible intermediate compound formation and shifting of the invariant points at various pressures. An expected shift in the eutectic composition to lower potassium content with an increase in the halt temperature on increasing pressure was confirmed. A merging of the meritectic and eutectic points at 343 ±2°K and 37 ±3 kbars occurred …

Ii, Proton Dissociation From Adenosine, Several Monosaccharides And Related Compounds. Iii, Proton Dissociation From Several Pyrimidines And Their Nucleosides At 10, 25 And 40°, Joseph Howard Ryttling
Theses and Dissertations
The log K, ΔH° and ΔS° values for the interaction of several metal ions with the two isomers of the cyclic polyether, 2,5,8,15,-18,21 hexaoxatricyclo[20.4.0.0^9,14]hexacosane are reported. The stability order found for alkali metal ion interaction with either isomer is identical to the order of ion permeability through reconstituted biological membranes for structurally related antibiotics. The size of the metal ion is critical in determining the extent of interaction. A calorimetric titration study of proton ionization from several monosaccharides and derivatives, pyrimidine bases and their nucleosides, adenosine and its derivatives, and cycloheptaamylose is described. The heats of reaction obtained in this …
A Study Of Folic Acid Dependent Reactions In Bovine Brain, Dillard Spencer Broderick
A Study Of Folic Acid Dependent Reactions In Bovine Brain, Dillard Spencer Broderick
Theses and Dissertations
The enzymatic interconversion of serine to glycine and N5, N10-methylene tetrahydrofolate to N5 -methyl tetrahydrofolate have been studied in a cell-free system derived from bovine brain. A partial purification of serine transhydroxymethylase and N5, N10 -methylene tetrahydrofolate reductase has been achieved by ammonium sulfate fractionation, protamine sulfate fraction, and by various column chromatography procedures. The two enzymes studied catalyze sequentially the reductive transfer of the hydroxymethyl group of serine to the N5 position of tetrahydrofolate forming N5 -methyl tetrahydrofolate. The products of these reactions were assayed by the incorporation of C14 from a one-carbon precursor i.e., L-beta-(C14)-serine, or N5 -methyl …

The Catalytic Hydrogenation Of Benzodiazines.|Ni.|Pphthlazine.|Nii.|Pquinazoline, Danny Lee Elder
Theses and Dissertations
Quinazoline and phthalazine were hydrogenated at low pressure and temperature (60 psi, room temperature) and high pressure and temperature (2000 psi, 100°C, 150°C} in neutral and acidic solvents over 5% Pd/C, 5% Ru/C, 5% Rh/Al2O3 , 5% Rh/C, and 5% Pt/C. Chromatographic methods for determining the qualitative and quantitative composition of hydrogenation mixtures were developed. The compositions of quinazoline and phthalazine-hydrogenation mixtures were determined. Eight phthalazine-hydrogenation products were detected and isolated: (1) 1,2-dihydrophthalazine, (2) 1,2,3,4-tetrahydrophthalazine, (3) a,a'-diamino-o-xylene, (4) o-methylbenzylamine, (5) 1,3-dihydroisoindole, (6) o-xylene, (7 and 8) cis- and trans- 1,2-dimethylcyclohexane. These products were identified by isolating them from reaction mixtures …

Optimization Of Physical Properties Of Hydraulic Cushion Cells For Vehicle Impact Restraint, William Evans Hughes
Theses and Dissertations
In recent years, the United States has witnessed a vast expansion of its internal highway system. Concurrently the number of vehicles has increased as has the average yearly milage per vehicle. Unfortunately, along with increased vehicle use there has been an alarming increase in annual loss of life and property due to traffic accidents. Statistics verify that the modem freeway systems greatly reduce dangerous head on collisions but the rate of accidents due to collisions with fixed objects in or near the roadway has increased almost 50 percent in the past thirty years.^1 In 1966, about 13>300 deaths were …
Solid-Liquid Phase Equilibria Of The Sodium-Rubidium And Sodium-Potassium-Rubidium Alloy Systems, Chen-Chao Hsu
Solid-Liquid Phase Equilibria Of The Sodium-Rubidium And Sodium-Potassium-Rubidium Alloy Systems, Chen-Chao Hsu
Theses and Dissertations
Thermal methods were used, to determine with high precision, the solid-liquid phase equilibria diagrams for the sodium-rubidium and sodium-potassium-rubidium systems. In the sodium-rubidium system, the results differ greatly from those of earlier works, especially near the eutectic composition where differences in freezing points as large as 25°K occur. A detailed search was made for possible intermetallic compounds (especially Na2Rb). Neither slow temperature cycling in the temperature range where compound formation could occur nor extended periods of annealing just above the eutectic temperature produced any evidence for compound formation in the sodium-rubidium system. A 2:1 (sodium to rubidium) sample was subjected …
Mechanism Of Water Transport Through Reverse Osmotic Membranes, Cheryl Kay Murphy
Mechanism Of Water Transport Through Reverse Osmotic Membranes, Cheryl Kay Murphy
Theses and Dissertations
Cellulose acetate membranes show a higher permeability to water than to salt and are being used for desalination of salt water by reverse osmosis. Use of highly acetylated cellulose membranes give a higher salt rejection but also decrease flow rate of the water. The addition of very-short-chain substances or alkyl groups larger than one carbon atom to the cellulose membrane also decreases water flux. A proposed mechanism of transport through the membrane is that the water molecule is passed along the chain by hydrogen bonding with the acetyl groups, The NMR shows a change in the chemical shift of water …

Theses and Dissertations
Earlier work in these laboratories on the heterotricyclic system 2,6-dioxa-10-azatricyclo[5.2.1.04,10]-decane, formed from 1,4-diketones and 2-amino-1,3-propanediols by a product-water-azeotroping procedure, was extended with the synthesis of analogous compounds, e.g., the 1,4,7-triethyl-, 1,7-dimethyl-4-isopropyl-1,7-diethyl-4-isopropyl-, 1,7-dimethyl-3- and 4-phenyl- compounds. The 1,7-dimethyl heterotricycle, the kinetically-controlled product, was accompanied by the thermodynamically-controlled product, 2-(2,5-dimethyl-1-pyrryl)-1,3-propanediol. The 1,7-diethyl heterotricycle was also accompanied by the isomeric pyrrole as were the 1,7-dimethyl-3- and 4-phenyl compounds. A scheme postulating a common intermediate is presented. The interesting analogous compounds, 1,7-dimethyl-2-oxa-6-thia-10-azatricyclo[5.2.1.04,10]decane, 1,4,7-trimethyl-2,6-dioxa-11-azatricyclo[5.3.1.04,11]undecane and 11-hydroxymethyl- and 11-methyl-9,13-dioxa-14- azatetracyclo[6.5.1.02,7 011,14]tetradeca-2,4,6-triene were also prepared. The syntheses in good yields of a considerable number of moderately to …

Theses and Dissertations
High pressure, high temperature technics were employed to successfully synthesize HoTe1.7, ErTe1.7, TmTe1.7, LuTe1.7, YTe1.7, and LuTe3. The pressure-temperature regions in which synthesis of each compound is successful were determined. Pressures to 100 kbars concurrently with temperatures to 1200 °C were used in an attempt to prepare ScTe1.7 and ScTe3, but these efforts met with failure. X-ray studies of these new compounds confirmed that they are extensions of the LTe2-X (0≤x
Social Structure Of Small Mammal Populations At The National Reactor Testing Station, Idaho, R. Lynn Speth

A Study To Establish Criteria For Creating Thematic Literature Units Appropriate To Lds Secondary Schools In The South Pacific, And The Creation Of Three Such Units, Ronald F. Malan
Theses and Dissertations
The purpose of this study was twofold: (a) to develop criteria for creating thematic literature units appropriate to the English language facility and to the culture of students in the LDS secondary schools in the South Pacific, and (b) to create three thematic literature units at the Form 5 (11th grade) level which would exemplify the recommended criteria.
An analysis of questionnaire responses revealed that a concept-centered approach to literature should take precedence, with geographical literature—especially Polynesian—also receiving emphasis. Less attention should be given to developing skill in literary analysis, and more focus placed upon systematically reinforcing other language arts …
