A Computer Simulation Of A Partial Venous System Of A Human Lower Extremity, David C. Smith

Theses and Dissertations

The human body is truly a fascinating and complex creation of our Maker. Because of the complexity and variability, many of its workings were little known until recent years. Some of the more amazing facts of the circulatory system follow. If the individual blood vessels of a single adult, i.e., artery, arteriole capillary, venule and vein, were laid end to end, they would extend more than 60,000 miles. For the average adult, the heart beats 70 times per minute; for the well-conditioned athlete, 50-60 beats per minute; and for the extraordinary athlete, as few as 37 times per minute. The …

An Ecological Life History Of Tall Bluebell In Utah, Verl B. Matthews

Theses and Dissertations

The ecological life history of tall bluebell, Mertensia arizonica Green var. leonardi (Rydb.) Johnston (M. leonardi Rydb.), was investigated during 1963 and 1964. Summer field studies were conducted on the Mud Creek Sleep Allotment of the Uinta National Forest, Wasatch County, Utah. Laboratory and herbarium studies were carried out at Brigham Young University. Specific objectives were to investigate seed germination, seedling development, root system, phenology, palatability, and describe the physical site factors where bluebell occurred. A study of this species was necessary because much of the herbage produced in certain areas of aspen range is not utilized. This condition occurs …

Characterization Of A Soluble Form Of Structural Protein From Neurospora Crassa, Clarence Denis Perterson

Theses and Dissertations

The study of membrane assembly has, until now, consisted of fractionating a membrane into its components or of assembling model membranes from non-physiological components. A native precursor to membranes was obtained as a quasi-crystalline material. It was the purpose of this work to develop the appropriate techniques for characterizing the material as well as to carry out the characterization. The results of the characterization indicate the quasi-crystalline material contains a single protein, structural protein. This protein is in two forms which may reflect two sequential steps in membrane assembly. One form is solubilized in 2-chloroethanol and isolated by gel filtration. …

A Taxonomic Revision Of The Weevil Genus Tychius Germar In America North Of Mexico (Coleoptera: Curculionidae), Wayne E. Clark

Brigham Young University Science Bulletin, Biological Series

A study of morphological characters of 4,000 adult weevils used in preparing a key and descriptions indicates there are fifteen North American species in the genus Tychius Germar. Adults occur on plants in the genera Astragalus, Baptisia, Hedysarum, Lotus, Lupinus, and Oxytropis.

The genus is divided into two species groups. The T. sordidus group appears to have representatives in the Old World fauna, but the T. semisquamosus group is probably native to North America. New names, Tychius caesius, and T. hirsutus are proposed for T. armatus Green, 1920 (not Tournier, 1873), and T. hirtellus LeConte, 1876 (not Tournier, 1873) respectively. …

A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

Little work has been done previously on the taxonomy of Crotaphytus collaris baileyi. This and the demonstration by Fitch and Tanner that C. c. baileyi is a heterogeneous grouping prompted the present study. Only the populations of the type material, the Upper Colorado River Basin, and the Chihuahuan Desert were studied. Multivariate, variance, canonical and discriminant analyses of external characters were performed, and pattern-coloration characters were examined on living specimens.

The results of the analyses show significance between all three populations. The discriminant functions distinguished between the populations with 80% reliability and patternal characters were discriminatory with near 100% reliability. …

Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz

Faculty Publications

Using a set of commercially prepared sodium ferrocyanide absorbers enriched to 91.2% Fe57 the Lamb-Mössbauer factor was measured to be 0.28±0.03. The thickness of Fe57 for these absorbers was measured using x-ray absorption techniques and was found to be considerably smaller than that advertised by the manufacturer even after correcting for the size of the ferrocyanide particles in the absorbers.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

An Analysis Of The Role Of Temples In The Establishment Of Zion, C. Max Caldwell

Theses and Dissertations

The establishment of Zion has been a goal of interest to every dispensation. The building of temples and participation in temple ordinances has likewise been a practice of many generations throughout history. In the present dispensation, Joseph Smith declared the need to construct temples in connection with the building of a Latter-day Zion.

The purpose of this study has been to discover a correlation between temple activity and the development of the Church membership in their preparation for the establishment of Zion. It has been concluded that the temples do perform a very significant role in the development of the …

History Of Utah's Salt Industry 1847-1970, John L. Clark

Theses and Dissertations

Utah salt makers have extracted salt from three sources, the principal of these being brine from Great Salt Lake. Other sources are saline beds in Great Salt Lake Desert and subterranean halite formations in central Utah.

This study traces the development of methods used to recover and refine salt by the industry, in general, and by specific companies. It provides brief, historical sketches of the major corporations and the economic, legal, and environmental factors affecting their growth.

Utah produces about 1 per cent of the nation's salt, exporting over half of it from the state. The major factors limiting the …

Two-, Three-, And Four-Particle Spatial Correlations Among Tertiary Cosmic Ray Muons, David D. Busath, R O. Stevenson

Faculty Publications

Showers of muons which result from interactions of primary cosmic rays high in the atmosphere appear deep underground as bundles of nearly parallel muons. For threshold energies of 1 TeV and arrival zenith angles of 45 degrees, those events having a small mean number of muons are described by a power law distribution in shower size having an exponent of ≅ -3.7 and a radial density distribution that decreases with distance R from the shower axis a little less rapidly than exp(-R/5.4 m). Comparison of new data on four muon spatial correlations in terms of the same phenomenology with data …

A Study Of The Contributions Of Andrew Jenson To The Writing And Preservation Of Lds Church History, Keith W. Perkins

Theses and Dissertations

Andrew Jenson, Assistant Church Historian, was one of the most prolific writers of LDS Church History. Born in Damgren, Denmark, he immigrated to Utah when he was fifteen years old. Because of his lack of training, his early life was spent in various manual labor occupations. None of these was satisfying to him; he longed for something better. He began compiling and writing Church history. In this he found much joy and happiness. His labors were soon recognized by the General Authorities of the LDS church, and he was permanently engaged as a historian in the Church historian's office. He …

Causes Of The Mormon Boycott Against Gentile Merchants In 1866 And 1868, Peter Neil Garff

Theses and Dissertations

In the 1850s and 1860s Gentiles monopolized the mercantile profession in Salt Lake valley. Conflict arose between the Mormons and anti-Mormon merchants for essentially five reasons: Mormon Church leaders believed merchants charged exorbitant prices, encouraged the coming of Johnston's army, falsely accused them for the "assassination" of two Salt Lake City Gentiles, supported Gentiles who were "jumping" Mormon land claims, and supported an adamantly anti-Mormon newspaper. Church leaders maintained that the motive behind these actions was essentially the destruction of their church; therefore, they levied a boycott against the anti-Mormon merchants in 1866.

Because Church leaders felt the coming of …

A Comparison Of Passages From Isaiah And Other Old Testament Prophets In Ethan Smith's View Of The Hebrews And The Book Of Mormon, William L. Riley

Theses and Dissertations

The Book of Mormon, having long been a work of great interest to me, became a natural area of study for my Master's program. I was directed by Roy W. Doxey and Paul R. Chessman who brought to my attention several areas of the Book of Mormon which needed to be investigated for clarification and deeper understanding. The area which was settled on centered around a book which was written seven years prior to the publishing of the Book of Mormon. The controversy which surrounds the View of the Hebrews by Ethan Smith is similar to the "Spalding Manuscript" controversy …

An Experimental Theatre Approach To A Mormon Theme Using The Work Of The Open Theatre As Prototype, Dionis C. Spitzer

Theses and Dissertations

The purpose of this thesis is to discover those experimental theatre techniques which can best express a Mormon theme: that one must become as a child to enter the kingdom of God. This thesis concludes from the resultant production, An Afternoon's Work, that certain theatrical techniques are powerful tools for the expression of any theme; that the work of the Open Theatre can be used for Mormon ends as long as the actor and director know exactly what they want to say and refine the techniques for that purpose.

The ideology behind experimental theatres such as the Open Theatre …
