An Optimization Technique Applied To The Determination Of Modal Damping Coefficients, Craig C. Smith Aug 1970

An Optimization Technique Applied To The Determination Of Modal Damping Coefficients, Craig C. Smith

Theses and Dissertations

Although analytical techniques are generally available for the simulation of dynamic systems, often these techniques require a great deal of computer time and storage. This difficulty was vividly pointed out by a previous thesis undertaken in this Department by R. L. Webster (1). Mr. Webster undertook the determination of orthotropic material properties using dynamic response test data from plates. A major difficulty which was encountered was the enormous amount of computer time required for the simulation. This thesis is an investigation of a method which when fully developed, may provide the ability to simulate such systems much more efficiently.

Preparation Of New Amino-, Thio-, And Sulfonyladamantane Derivatives, Joseph Craig Argyle Jun 1970

Preparation Of New Amino-, Thio-, And Sulfonyladamantane Derivatives, Joseph Craig Argyle

Theses and Dissertations

Various synthetic schemes were used to prepare a number of new amino-thio- and sulfonyladamantane compounds. By a nucleophilic substitution on 1-bromoadamantane, 1-(p-nitrophenylthio)adamantane was prepared from p-nitrothiophenol; the amino- and sulfonyl- derivatives of this compound were also prepared. Silver tosylate was used to generate the 1-adamantyl carbonium ion from 1-bromoadamantane in a synthetically useful procedure for preparing 1-adamantylamides from nitriles. Three 1-(1-adamantylcarbinyl)-2,5-dialkylpyrroles were prepared by Knorr-Paal reactions and reduced to the corresponding pyrrolidines. Thio- and aminomethyl 1-adamantyl ketones were prepared from methyl and bromomethyl 1-adamantyl ketones, respectively. Aliphatic and aromatic oxiranes were reacted with 1-aminoadamantane in a bomb at elevated temperatures …

High Pressure Spectral Chemistry Of Selected Organic Compounds, Frank William Linsley Jun 1970

High Pressure Spectral Chemistry Of Selected Organic Compounds, Frank William Linsley

Theses and Dissertations

The series of compounds indicated by the formular C_6H_5-(CH=CH)n-C_6H_5 change in color from white (colorless) to yellow to orange to red to deep red as n increases from 1 to 12. Stilbene is the first compound of this series (n=1). Under pressure, exerted by a diamond anvil press, stilbene can be seen to change color from white to yellow to red as increasing pressure is applied. Similar color changes are observed for the compounds where n=2,3, and 4 when subjected to similar pressure. This study records and reports the spectra versus pressure for these compounds.

Calorigenic Effects Of Thyroxine And Triiodothyronine On Rat Diaphragm., Robert Lee Chambers Jun 1970

Calorigenic Effects Of Thyroxine And Triiodothyronine On Rat Diaphragm., Robert Lee Chambers

Theses and Dissertations

Since the isolation of triiodothyronine (T3) by Pitt-Rivers and Gross (1953) several questions as to its role as a thyroid hormone arose. Does T3 have the same or different actions than that of thyroxine (T4 )? Is T3 an emergency hormone, since its synthesis relative to T4 is greatly increased during periods of low iodine intake and its response time is I/5th that of T4 (Ackerman and Arons, 1958)? Are there any interactions modifying their respective actions?

The Synthesis And Properties Of New Potentially Chemotheraputic [Sic] Pteridine Derivatives, Walter Wesley Parish Jun 1970

The Synthesis And Properties Of New Potentially Chemotheraputic [Sic] Pteridine Derivatives, Walter Wesley Parish

Theses and Dissertations

A new general synthetic method for the preparation of 6-thiopteridines has been developed. The method involves the addition of thiols to intermediate pyrimidine nitrones formed in situ by the reaction of 4-amino-5-nitrosopyrimidines with pyridinium-activated acetonitriles, acetates, acetophenones, and other methylketones. Ca. forty new pteridines were prepared by this method. The preparation of six new 6-pteridinyl ketones, two new 6- pteridinyl ketone thiosemicarbazones, and two new 6-sulfonylpteridines and their 4-acetamido derivatives is also reported. 4-Acetamido-2- amino-7-phenylpteridine 5-oxide was prepared by the reaction of 2- amino-4,6-diacetamido-5-nitrosopyrimidine with either phenylsulfonyl-acetophenone or phenacylpyridinium bromide. Evidence relating to the structure of the acylated 4-amino-5- nitrosopyrimidines …

The Introduction Of Asian History Into Utah High Schools, Carol M. Hinckley May 1970

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 Mar 1970

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 …

Proposed Thermodynamic Pressure Scale For An Absolute High-Pressure Calibration, Daniel L. Decker, J. Dean Barnett Feb 1970

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.

Asymptotic Evaluation Of Wkb Matrix Elements. Ii. Use Of Langer's Uniform Asymptotic Wavefunctions, Wesley D. Smith, Russell T. Pack Feb 1970

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%.

A History Of The Deseret Alphabet, Larry Ray Wintersteen Jan 1970

A History Of The Deseret Alphabet, Larry Ray Wintersteen

Theses and Dissertations

The Church of Jesus Christ of Latter-day Saints during the years 1852-1877, introduced to its membership a form of rhetoric (writing system) called the deseret alphabet (phonetic alphabet). This experiment was intended to alleviate the problem of non-communication which was created by the great influx of foreign speaking Saints into the great Salt Lake Valley.
The alphabet was developed and encouraged by the Prophet Brigham Young and a few followers. Much to their dismay the members of the Church did not have the same vision of its workability as did its promoters.
This new alphabet appears not to have met …
