Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown Aug 1967

Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown

Theses and Dissertations

The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …

A Study Of Thermal Responses Of A Body Of Complex Geometry To A Moving Heat Source, J. Norman Smith Aug 1967

A Study Of Thermal Responses Of A Body Of Complex Geometry To A Moving Heat Source, J. Norman Smith

Theses and Dissertations

The effect of the fusion welding process upon the metals being welded is a matter of great interest and has been the subject of much investigation, both theoretical and experimental. The properties of metals are determined by the structure of their crystals (within limits for any given metal), and the crystalline structure is determined by heating and cooling rates. Thus the knowledge of temperatures, and heating and cooling rates, becomes the key to understanding these effects of heating. Since the greatest part of fusion welding is done using a gas torch or an electric arc, the necessary theoretical study is …

The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards Aug 1967

The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards

Theses and Dissertations

Due to a lack of taxonomic and distributional information concerning the Common Crow Corvus brachryhynchos Brehm inhabiting the Great Basin of North America, Johnston (1961) in one of the most recent revisions on crows, was unable to include this area in his work. Between 1965 and 1967, field trips were taken throughout the Great Basin to secure specims, and to determine to what extent the area was being utilized by crows. Ecological information such as habitat prference, nesting behavior, and interactions with other species was collected where possible. Forty-eight birds were collected from the Great Basin. From a comparison of …

The Design Of A One-Man Terramechanism, Brent Charles Fryer

Theses and Dissertations

With the rebirth of special warfare in the last few years, the role of the individual soldier and of squad-sized units has been re-emphasized. Most guerilla-type fighting has been, is presently, and will most likely continue occurring in remote areas of the world. The terrain encountered may be tropical grasslands and canopy areas, or rugged mountains, inland waterways, swamps, mud flats and rice paddies. Other adverse terrain conditions are frequently encountered and must be crossed to accomplish the mission of the unit.

A Geographical Analysis Of The Emergence And Subsequent Disappearance Of The Cotton Industry In The Virgin River Basin (1856-1910), Brooks Kent Hanson Jan 1967

A Geographical Analysis Of The Emergence And Subsequent Disappearance Of The Cotton Industry In The Virgin River Basin (1856-1910), Brooks Kent Hanson

Theses and Dissertations

At one time the cotton industry in Utah was a flourishing activity. Many pioneer farmers were engaged in the growing of this staple for the purpose of providing much needed cotton for the Territory of Utah before the days of railroads and highways. After the favorable climatic conditions for agriculture in Utah's Dixie were discovered, leaders of the Latter-day Saint Church made plans for the growing of many fruits and vegetables of the temperate zone. Of these, cotton received by far the most attention, as a domestic source of this raw material was at one time vital to the well …

Geographical Characteristics Of Early Mormon Settlements, John Haws Baum Jan 1967

Geographical Characteristics Of Early Mormon Settlements, John Haws Baum

Theses and Dissertations

Considerable literature has been written about the Mormons and their settlement of the lands within the Great Basin; yet no one has produced a systematic study which analyzes the following geographical factors: What pattern of land occupancy was actually used by these early pioneers? Which physical characteristics determined the selection of a site for the Mormon village? What type of city survey pattern was instigated as towns were established along the eastern margin of the Great Basin? What was the relationship between the forts and the settlements in their lay-out patterns? As these questions were systematically analyzed new findings were …

A Study Of The Attitudes Of Latter-Day Saint Seminary Students Toward Certain Church Standards Of Dress And Conduct, Alfred Lawrence Pace Iii Jan 1967

A Study Of The Attitudes Of Latter-Day Saint Seminary Students Toward Certain Church Standards Of Dress And Conduct, Alfred Lawrence Pace Iii

Theses and Dissertations

Standards of dress and conduct of the Church of Jesus Christ of Latter-day Saints are presented to the youth in a variety of ways. Although these standards are all important, the seminary youth do not consider them to have equal relevance in their own personal lives; for they are concerned with particular standards, in particular ways, and at particular times. While some attempts have been made to solicit their views pertaining to such standards, most studies to date have not dealt with material which has been published and made available to all of the youth of the Church. Since teachers …

Joys Of Discovery- Historical Research And Writing, Leroy R. Hafen Oct 1966

Joys Of Discovery- Historical Research And Writing, Leroy R. Hafen

BYU Studies

Brigham Young University history professor LeRoy Hafen lauds the merits of pursuing expertise in history, citing the thrill of discovery that historians feel when they uncover the facts. Hafen defines history as a cross between science and art—science because historians seek to find facts, art because the study of human behavior cannot always result in completely accurate discoveries. Additionally, history is an art because a historian must organize and retell the facts in an appealing way, striving for literary excellence as well as accuracy. Hafen describes the process of historical research, including making use of both primary and secondary sources …

Model Of Electron Correlation In Solids, Everett G. Larson, Walter R. Thorson Sep 1966

Model Of Electron Correlation In Solids, Everett G. Larson, Walter R. Thorson

Faculty Publications

The usual Hartree-Fock model (energy-band theory) does not always give an adequate description of electronic structure in a solid, because it ignores the effects of electron correlation. It was shown first by Wigner that such a situation always develops in an electron ''gas'' at sufficiently low density; a solid structure described by ''resonance'' of Heitler-London pair bonds between electrons localized on neighboring atoms is then a good model of the system.The transition from a Bloch-type state to such a highly correlated state as a function of electron density (lattice parameter) is a problem of considerable interest for the theory of …

Pressure Calibration To 100 Kbar Based On The Compression Of Nacl, R. N. Jeffrey, J. Dean Barnett, H. B. Vanfleet, H. Tracy Hall

Faculty Publications

An independent determination has been made of the transformation pressures assigned to the high-pressure transformations in Ba and Bi which are generally used for calibration points. The metals were imbedded in NaCl, and the transitions were detected by the resistance change of the metal while the NaCl lattice parameter was simultaneously measured by x-ray diffraction. The NaCl compression values determined at the fixed points were related to pressure by reference to the semiempirical compression curve of Decker. The Ba I-II and Bi III-V transformations at room temperature were assigned thermodynamic equilibrium values of 53.3 ±1.2 kbar and 73.8 ±1.3 kbar, …

Refinements In The Isomer Distribution And Relative Rate Of Sulfonation Of Toluene And Hydrochlorination Of Olefins With Stannic Chloride Catalyst, David George Guillot May 1966

Refinements In The Isomer Distribution And Relative Rate Of Sulfonation Of Toluene And Hydrochlorination Of Olefins With Stannic Chloride Catalyst, David George Guillot

Theses and Dissertations

The sulfonation of toluene at -12.5° C. with sulfur trioxide in liquid sulfur dioxide was found to give 10.03 ± 0.20 % ortho, 0.73 ± 0.20 % meta and 89.24 ± 0.20 % para isomers. This isomer distribution was determined by isotope dilution analysis using sulfur-35 enriched sulfur trioxide. After dilution of aliquots of the neutralized sulfonation mixture with pure sodium salts of each of the isomers prepared from the corresponding toluidines, the isomers were converted to the p-toluidine salts, purified by recrystallization, and counted by liquid scintillation counting. The relative rate of sulfonation of toluene compared to benzene was …

Cultural Implications Of The Sino-Soviet Conflict, Paul V. Hyer Apr 1966

Cultural Implications Of The Sino-Soviet Conflict, Paul V. Hyer

BYU Studies

The Sino-Soviet conflict is based as much in culture as it is in border disputes or ideological approaches to communism. The Chinese have lived for much of their collective past in isolation from the world and with a strong sense of ethnocentricity. China’s ancient traditions continue to shape the modern country’s attitudes and policies. If the United States wants to better understand China, it must begin by strengthening its understanding of the rich Chinese culture.

A Geographic View Of The Sino-Soviet Dispute, Alan H. Grey, Russell N. Horiuchi Apr 1966

A Geographic View Of The Sino-Soviet Dispute, Alan H. Grey, Russell N. Horiuchi

BYU Studies

This article looks at the impact geographical area has on the Sino-Soviet conflict. Although China and the Soviet Union have similar ideologies, both countries’ imperialist drives makes expanding borders inevitable. In addition, China’s geographical deficiencies—the small proportion of land suitable for agricultural development—and its growing population put pressure on the Chinese government to look elsewhere for resources to sustain its people. In this context, border conflicts are inevitable despite common ideologies.
