Distribution And Relationships Of Utah Brome Grasses In Western North America, Jerry B. Anderson Apr 1973

Distribution And Relationships Of Utah Brome Grasses In Western North America, Jerry B. Anderson

Theses and Dissertations

A considerable amount of study material has beccme available since the revision of the genus in 1900 by Shear, and the revision of the section Bromopsis in 1952 by Wagnon. A number of cytological studies have been done in recent years; and Wagnon's work pointed out the need for a comprehensive study of the entire genus. This study is a taxonomic revision of the Genus Bromus for the State of Utah, and contains illustrations and descriptions of the species; synonomy; distribution maps; and discussions of many of the important aspects of the economics, ecology, and historical treatment. I have recognized …

Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence Apr 1973

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 Apr 1973

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 …

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 Apr 1973

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 Apr 1973

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 Apr 1973

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 Apr 1973

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 Apr 1973

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 Apr 1973

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],

The Mysteries Of God, Noel B. Reynolds Mar 1973

The Mysteries Of God, Noel B. Reynolds

Faculty Publications

LDS discourse commonly uses the term mysteries to refer to truths that we don’t know or shouldn’t worry about. But the scriptures—and particularly the Book of Mormon—speak of the mysteries very positively, as something we should seek to know. The scriptural terminology appears to refer to the things of God that the faithful come to know—things that nonbelievers never understand.

Swiss In New Orleans, John Geiser Iii Feb 1973

Swiss In New Orleans, John Geiser Iii

Swiss American Historical Society Newsletter

In April of 1718, Pierre Le Moyne , Sieur de Bienville, Commandant General of the French colony of Louisiana, founded the City of New Orleans. For the next half century this was to be in reality a French city, named for the Regent and with streets called Toulouse, Chartres, Dumaine, Bourbon, Dauphine, and Rue Royale laid out according to the proper French plan around the Place d'Armes. The buildings were of a definite French style and the cultural and social lives of the settlers were as French as they could make them. The most popular French governors were the ones …

History Of The Swiss American Historical Society, Heinz K. Meier Feb 1973

History Of The Swiss American Historical Society, Heinz K. Meier

Swiss American Historical Society Newsletter

On Independence Day 1927, on the occa sion of the Swiss Singing Festival, a group of Swiss Americans living in the Chicago area decided to found a historical society. The idea had been in the air, so to speak. For some time , persons of different background and living in different parts of the country had been working diligently in that direction by encouraging existing Swis s societies to add another dimension to their activities and by gathering materials about "famous Swiss." They were annoyed and concerned "by the fact that every outstanding person of Swiss origin was claimed by …

The History Of Medical Relations Between Switzerland And The Usa, Erwin H. Ackerknecht Feb 1973

The History Of Medical Relations Between Switzerland And The Usa, Erwin H. Ackerknecht

Swiss American Historical Society Newsletter

When in a symposium concerning the medical relations of Switzerland to other countries reports are given on the relations of Swiss medicine to German, French, Italian, English and Austrian medicine, the reasons are obvious. But it might be at first sight surprising that the USA are added to this traditional list of neighbors. This surprise is partly a consequence of outdated technological and geographical thought. Actually, through the airplane, New York is as close to Zurich as by railroad are Hamburg or Paris. We should become conscious of this new situation. But partly doubts remain legitimate. Have the relations between …

A Proposed Mechanism Of Action For In Vitro Excystation Of Two Species Of Coccidia, William Ronald Jolley Jan 1973

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 …

Perceptions Of Personality From Speech: Effects Of Manipulations Of Acoustical Parameters, Bruce L. Brown, William J. Strong, Alvin C. Rencher Jan 1973

Perceptions Of Personality From Speech: Effects Of Manipulations Of Acoustical Parameters, Bruce L. Brown, William J. Strong, Alvin C. Rencher

Faculty Publications

A speech analysis-synthesis system was used to manipulate variance of fundamental frequency and a mechanical rate changer was used to manipulate speech rate. The synthesized and altered voices were tested for realism. Synthesized voices were mistaken for normal 50% to 58% of the time and rate-changed voices were mistaken for normal 78% of the time. Additional studies were conducted to test the effects of these acoustical manipulations on the adjective ratings judges made of speakers. Variance of intonation was increased and decreased by 50% for eight speakers. There was a significantrend for increased intonation to cause voices to be rated …

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 Jan 1973

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 Divine Nature Of God: A Study Of What Has Been Said And Taught About The Divine Nature Of God By Ancient And Modern Apostles And Prophets, Lester Young Moody Jan 1973

The Divine Nature Of God: A Study Of What Has Been Said And Taught About The Divine Nature Of God By Ancient And Modern Apostles And Prophets, Lester Young Moody

Theses and Dissertations

In this thesis prominent teachings of the apostles and prophets were examined on the subject of the divine nature of God. These teachings indicate that among the elements of the divine nature of God is his Holy Spirit, his glory or the light which emanates from his person. God's glory, spirit and light were compared and analyzed to determine their relationship to each other. It was found that they perform the same roles and functions and are often used synonymously. Other aspects of the divine nature were examined, such as life, love, truth and goodness.

The terms omnipotence, omniscience and …

The Correlation Program Of The Church Of Jesus Christ Of Latter-Day Saints During The Twentieth Century, Jerry Rose Jan 1973

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 Jan 1973

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 …
