Mammals Of The Lynndyl, Utah, Sand Dune Area : A Population Problem, Hugh J. Phillips

Theses and Dissertations

The purpose of this study was to determine the kinds, population, distribution, and general habits of the mammals of the Lynndyl sand dune area. Only one article concerning the dunes was found, but several have been written on other dunes; however, none was found concerning mammals. Two quantitative studies, plot and transect trappings, were made and general observations were taken within the study area. Three types of plots; Russian thistle, juniper, and baren moving dunes; were trapped and revealed the following species: Dipodomys ordii, Peromyscus maniculatus, Reithrodontomys megalotis, Onychomys leucogaster, and Neotoma lepida. The most numerous animal in all plots …

Some Aspects Of The Chemistry Of The Hydroquinoxalines Unsubstituted On The Nitrogen Atoms, Evan L. Allred

Theses and Dissertations

A search of the literature revealed that almost nothing is known concerning the class of compounds known as decahydroquinoxalines. Since this posed a problem involving a search for a systematic synthetic method of general application as well as a method for establishing the characteristic class and individual properties, a research project under the guidance of Dr. H. Smith Broadbent was initiated. Of particular interest aside from matters of purely chemical interest was the recognition that the hydroquinoxalines possess obvious structural similarities with atropine and other well-known drugs which have valuable application as hypotensive agents, analgesics, spasmolytic agents, parasympathetic depressants, antihistaminics, …

Acidic Properties Of Clay Minerals And Alumina, Kenneth H. Anderson

Theses and Dissertations

Acidic properties of dialyzed alumina and representative clay minerals were studied by performing titrations with various bases. For the first group of experiments the titrations were made in a water system using KOH and NaOH. For this study in a water system the experimental data includes individual cationic activities as well as pH values. Adsorption of the cations was adequately described over a pH range of 5-11 by the equation 1-θ/θ ⋅ aNa+ ⋅ aOH- = 1/K'3 [aOH- + KW/K'2 + 1/K'1], in which θ represents the fraction of the total sites that have reacted. Thermodynamic constants K'3 and K0= …

The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson

Theses and Dissertations

Recent investigations on the crude pigeon liver extracts have shown the presence of an enzyme which catalyzes the oxidative decarboxylation of malate to pyruvate and carbon dioxide. The name malic enzyme has been given to this enzyme to distinguish it from malic dehydrogenase. Under aerobic conditions the addition of ferrous sulfate resulted in inhibition of the action of malic enzyme. Subsequent investigation showed that the inhibition obaerved was not due to ferrous ions, but due to ferric ions which were contaminating the ferrous sulfate. It was also shown that under aerobic conditions ferrous ions were rapidly oxidized to ferric ions. …

Colorimetric Determination Of Rhenium In Ores, Clair Winston Rogers

Theses and Dissertations

The problem of colorimetrically determining rhenium in the presence of molybdenum, copper, iron, sulphur, and rare earth elements with the use of dimethylglyoxime as the complexing compound was accomplished by the method reported here-in. The interfering elements were eliminated either as gaseous oxides and sulfides or were precipitated from a highly basic solution by means of a strong alkaline fusion of equal weights of sodium hydroxide and sodium peroxide, and the ore sample containing rhenium. The fusion product was dissolved in water, the solution boiled with a slight excess of sodium peroxide, and the hydroxide of all the interfering ions …

An Ecological And Distributional Study Of Small Mammals Of Cedar Valley, Utah County, Utah, Loraine Woodbury

Theses and Dissertations

This paper deals with the ecology and distribution of small mammals in the following plant communities of Cedar Valley, Utah: juniper, greasewood, grass-rabbitbrush, and shadscale. Study periods were in August 1950 and 1951, October 1951, and April 1952 with each community studied 1,440 trap-nights. A combination of the Calhoun ''B" and transect method was employed; plant species and densities were taken and soil samples were checked for moisture content, total soluble salts and mechanical analysis. In the communities studied Dipodomys ordii utahensis (Merriam) is found in greatest abundance on sandy soil and Perognathus parvus olivaceus (Merriam) is found in greater …

A Study Of The Families Of Utah Hemiptera, Gerald L. Nielsen

Theses and Dissertations

This study determines the number of families of Hemiptera found in the state and has a key for their classification. The characteristics and general distributions of each family are given, along with specific examples of the most common and economically important bugs. Important references are given for each family of work done to date. It was found that there have been twenty-eight families of Hemiptera collected in Utah, some of which are well represented in numbers of genera, species, and individuals, while others are represented by a single species and collected in only one or two places in the state.

Thermodynamic Properties Of Water Adsorbed On Kaolinite, S. John Bennett

Theses and Dissertations

The object of the work presented in this thesis was to obtain quantitative values of the thermodynamic changes in water upon adsorption by kaolinite. Two methode were used. The first was a determination of the differential heat content and entropy of adsorption. The second method included a thermodynamic evaluation of the B.E.T. "c" constant expressed in terms of the Gibbs standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential and standard thermodynamic functions or free energy, entropy, and heat content of adsorption. The adsorption of water on kaolinite appears to be a van der …

A Study Of The Problem Of A Personal Devil And Its Relationship To Latter-Day Saint Beliefs, Lamar E. Garrard

Theses and Dissertations

The problem of the existence of a devil is important, since it relates to other beliefs which a person or his religion may uphold. The orthodox Christian concepts of the divinity of Christ, the Fall of man, the Atonement, and the inspiration of the Bible are altered when a belief in Satan is discarded.

The prophets of the Church of Jesus Christ of Latter-day Saints (Mormon) take a very definite stand concerning the existence of Satan. They declare that the devil and his angels exist and that they tempt and try to deceive men. L.D.S. scriptures, given through modern revelation, …

A Study Of The Nature Of And The Significance Of The Changes In The Revelations As Found In A Comparison Of The Book Of Commandments And Subsequent Editions Of The Doctrine And Covenants, Melvin Joseph Petersen

Theses and Dissertations

An observation of literature extant regarding the revelations accepted by the Church of Jesus Christ of Latter-day Saints as being divinely given through Joseph Smith, discloses that the field has not been probed very thoroughly. Many are the sermons and discourses preached from the pulpit by exegetes of Mormonism vindicating the book of Doctrine and Covenants as being authentic. Few, however, have made a study of the history, origin, and development of this book.

From outside of the church criticisms have arisen concerning certain changes, additions, and omissions made in the revelations as first written by Joseph Smith. When confronted …

Recent Jewish Movement In Israel In Light Of The Teachings Of The Latter-Day Saint Prophets, Dale Thomas Tingey

Theses and Dissertations

The Juarez Stake Academy, Dale M. Valentine

Theses and Dissertations

While the history of the Latter-day Saints who colonized in Mexico is probably not generally known by the majority of Latter-day Saints living throughout the world today, it nevertheless comprises an exceptionally colorful and exciting chapter of the history of Mormonism. The Latter-day Saints who went to Mexico created there a culture and society which has never been duplicated. Probably one of the chief concerns of the Mormon Colonists in Mexico was to establish in their society a culture which would be lastingly enduring and which would progressively improve. Secondly, it is also probable that they were passionately desirous of …

The Origin And History Of The Fast Day In The Church Of Jesus Christ Of Latter-Day Saints, A. Dean Wengreen

Theses and Dissertations

The purpose of this study is two fold: first, to review the historical sources pertaining to the observance of fasting from the time of the establishment of the church in 1830 until 1896, when the last essential change in its observance occurred; and second, as the payment of fast offerings is so closely related to an analysis of the subject, to trace its development out of the Church's policy to provide for its poor.

Latter-Day Saint Servicemen In The Philippine Islands: A Historical Study Of Their Religious Activities And Influences Resulting In The Official Organization Of The Church Of Jesus Christ Of Latter-Day Saints In The Philippines, Lowell Eliason Call

Theses and Dissertations

Though generally unheard of in the Western world and the United States prior to the Spanish-American War of 1898, the Filipino people have made some remarkable contributions to world leadership and world history. Frequently they have been considered a pagan and an ignorant people, although in objectively observing them one finds such a belief unfounded and even the reverse of that to be true. Progress which the republic has made during the last fifty years, since being liberated to develop liberties in religion, politics, and education, is phenomenal, even when compared with the United States period of evolution to her …

Mormon-Indian Relations As Viewed Through The Walker War, H. Bartley Heiner

Theses and Dissertations

Early Utah history involved many adjustments of differences between the pioneers and the Indians. This thesis is a study of the differences and of the policies adopted to alleviate them, particularly in the background, setting, and events of the Walker War.

The Mormons came into a territory inhabited by the aggressive Ute Indians. However, the niggardness of nature and the white man's oppression had reduced them to a condition of destitution. They had descended to trading, begging, and stealing. Possibly, with the idea of exploiting the Mormons, the Indians invited them to settle in various sections of the territory. The …
