Mites And Lice Of The National Reactor Testing Station, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

Mites of 47 species and lice of 16 species were taken from reptiles of 3 species, birds of 23 species, and mammals of 18 species at the National Reactor Testing Station between June, 1966, and September, 1967. Mammals differed in degree of infestation relative to their geographic distribution at the station. The number of species of ectoparasites which occurred on a particular kind of host generally was in direct proportion to the number of hosts examined, but exceptions occurred in some instances. In some cases the rate of infestation differed relative to the sex of the host. The greatest numbers …

Distribution Of The Native Trees Of Utah, Kimball S. Erdman

Brigham Young University Science Bulletin, Biological Series

Although botanists have been actively collecting in Utah for well over a century, the distribution of many plants are as yet imperfectly known. This is, in part, due to the scattered nature of Utah herbarium material. Also the terrain of the state has impeded collection in more rugged and remote areas. The present study gathers together the data from the major collections of native Utah trees and clarifies our present understanding of tree distributions in the state. The older collection records have been extensively supplemented by the field work of the author and other botanists.

The great diversity of environments …

Effects Of X-Irradiation On The Brain Of White Rats, Bernell K. Dalley

Theses and Dissertations

With the advent of the atomic age, a great deal of attention has been given to the effects of radiation of various types on the living organism. Some emphasis was placed also on the particular effects damaging radiation has on the central nervous system. Of particular importance was the dis -covery of the high resistance to irradiation exhibited by the central nervous system, and the observation of a latent period after exposure, during which the individual appears normal, followed by deterioration and death. Explan - ations of this unique reaction have caused some controversy and, currently, one of two theories …

The Effects Of Various Treatments On Thiamin Diphosphate And Total Thiamin Levels Of Rat Tissues, Dong Hwa Park

Theses and Dissertations

Tissue thiamin diphosphate was assayed enzymatically utilizing purified brewer's yeast apotransketolase. With this assay ten uumoles of thiamin diphosphate could be detected. Total thiamin was fluorometrically measured. For one to three days rats were placed under conditions of stress, consisting of loud noise treatment, emotional stress, deprivation of paradoxical sleep, and swimming to exhaustion, respectively. The body weight was markedly decreased at the end of the respective experimental periods except with the loud noise treated group, compared with the corresponding controls. Following two to three such consecutive treatments, the adrenal weight also showed a significant increase. Thiamin diphosphate and total …

The Chemistry Of Dehydronaphthalene, Richard Harold Hales

Theses and Dissertations

The reaction of monohalonaphthalenes with potassium t-butoxide in a t-butyl alcohol-dimethyl sulfoxide (DMSO) mixture has been studied. The 1-bromonaphthalene reaction was extensively studied. Fifteen identifiable products were observed and conditions were found where the desired products, 1- and 2-t-butyl naphthyl ethers (V and VI) were formed in maximum yield, and their decomposition products, 1- and 2-naphthol (XIV and XV), were formed in minimum yield. The mole percent ratio of 1-substituted products (V and XIV) to 2-substituted products (VI and XV) was found under standardized conditions to be 0.35 ± 0.03 in every case when the halogen was I, Br and …

Osteological And Mylogical Comparisons Of The Head And Thorax Regions Of Cnemidophorus Tigris Septentrionalis Burger And Ameiva Undulata Parva Barbour And Nobel (Family Teiidae), Don Lowell Fisher, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The anterior osteological elements of the skull, lower jaw, and wrist along with the anterior myological characters discussed and figured in this report suggest that A. u. parva and C. t. septentrionalis are members of distinct groups which can be differentiated by internal morphologic characters. Although comparisons were restricted to highly geographically separated individuals of the same family, their general body form and structure appear to be similar.

A great number of anatomical structures are shared in common, but the significant differences between them include:

1. General skull appearance. The skull of C. is generally lighter, that is the bones …

Pinyon-Juniper Succession After Natural Fires On Residual Soils Of Mesa Verde, Colorado, James A. Erdman

Brigham Young University Science Bulletin, Biological Series

A mountain brush vegetation typified by Gambel oak (Quercus gambelii) and serviceberry (Amelanchier utahensis) dominates the uplands of Mesa Verde National Park. There is evidence that this brush element is a successional stage that has been maintained by repeated natural fires in a large part of the Mesa Verde landscape. This study was conducted to determine the role of fire in the region's ecology, the nature of the climax pinyon pine (Pinus edulis) and Utah juniper (Juniperus osteosperma) vegetation, and the major successional stages that lead to the climax condition.

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

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 …

A Study Of The Factors Affecting Lds Institute Enrollment Among Students From Homes Of Parents Who Are Inactive In The Lds Church, Boyd Leslie Robertson

Theses and Dissertations

The purpose of this study is to determine if there are differences in characteristics of home environment, school environment, or within the students themselves, between college students enrolling in classes taught at the LDS Institute of Religion, who come from homes where both parents are "inactive" in the LDS church, and a similar group of students who do not enroll.

The Dream Mine: A Study In Mormon Folklore, Joe Stanley Graham

Theses and Dissertations

In September of 1894, John Hyrum Koyle, Jr., said that he was shown in a dream or vision a large, rich deposit of gold and an underground storehouse of artifacts hidden by people of Ancient America. This dream was the beginning of a mining venture which has never produced anything of value, has been opposed vigorously by both officials of the LDS Church and the State, yet has claimed supporters numbered in the thousands.

The mine has profoundly affected (and continues to affect) the lives of many families who have come into the sphere of its influence. The lore of …
