Raptor Temperature Regulation And Energetics, James Arthur Mosher

Theses and Dissertations

A review of energetics studies of raptorial species introduces four separate studies of temperature regulation by raptors. Golden Eagle (Aquila chrysaetos) nest site selection, as influenced by direction of exposure, is discussed. The data show strong directional preferences to the NNW by southern populations and SSE by northern populations. The tarsometatarsus is shown to have a thermoregulatory function in large falcons, and adaptations of this mechanism to varied habitats are examined. Color phase in Screech Owls (Otus asio) is shown to be related to metabolic differences that may explain the distributions of the color morphs. Development of thermoregulation in Flammulated …

Close Coupling Test Of Classical And Semiclassical Cross Sections For Rotationally Inelastic Ar-N2 Collisions, Russell T. Pack

Faculty Publications

Accurate quantum mechanical close coupling (CC) integral cross sections are reported for rotationally inelastic Ar-N2 collisions at room temperature using an empirical intermolecular potential. These cross sections are used to test the infinite order sudden (IOS) approximation and the results of several methods [classical trajectories (CT), full sudden (SA), generalized phase shift (GPS), and classical limit generalized phase shift (CGPS)] as reported in the preceding paper by Pattengill. The IOS approximation works very well for cross sections involving low rotational states. The CT method works well for all the cross sections examined, justifying the popular belief that the rotational motion …

A Comparative Investigation Of Mammalian Serine Transhydroxymethylases, Sanha Panichajakul

Theses and Dissertations

Serine transhydroxymethylase was purified one thousand-fold from bovine brain and one hundred and twenty-fold from bovine liver. Both enzymes were yellow due to the presence of the coenzyme pyridoxal 5'-phosphate. Polyacrylamide gel electrophoresis of the liver enzyme showed one major band containing 95% of the protein, while in the case of the brain enzyme two major bands of nearly equal intensity were observable. The specific activity of the crude liver enzyme was about sixty times higher than that of brain. The liver enzyme was also more heat stable than the brain enzyme. The purified enzymes exhibited L-allothreonine and L-threonine aldolase …

A Comparative Study Of Some Population Characteristics Of Calyptraea Fastigiata Gould, Crepidula Lingulata Gould, And Crepidula Nummaria Gould (Gastropoda, Prosobranchia), Roger Harold Goodwill

Theses and Dissertations

A comparative study of the field populations of Crepidula lingulata, Crepidula nurnmaria, and Calyptraea fastigiata indicated all three preferred a rocky substrate but favored different size rocks. Their positions on the rocks varied but the greatest numbers were found attached to the undersides. Crepidula lingulata and C. nummaria preferred larger rocks and were found in intraspecific associations more often than C. fastigiata which preferred smaller rocks. These associations occurred with a 1:1 sex ratio; however, the overall population did not. Crepidula lingulata had a high female count and C. fastigiata a high male count. Males, of all three species, were …

The Kinetics And Mechanism Of A Free Radical Decay In Aqueous Solution, Denzel Lee Fillmore

Theses and Dissertations

The decomposition of nitrosyl disulfonate ion was studied in strongly alkaline solution of 10-2 to 5 m sodium hydroxide. The decomposition was found to be first-order in both hydroxide and nitrosyl disulfonate ions. A multi-step mechanism involving sulfite ion, sulfite ion radical and nitrosyl monosulfonate ion radical as intermediates was proposed, with the initiating step being the SN2 replacement of a sulfite ion by a hydroxide ion. The rate constant for the initiating step ranged from 1.2 x 10-7 to 2.25 x 10-5 M-1s-1 for the solution concentration range of the study. The products of the decomposition were identified as …

Composition, Time, And Size Distributions Of Airborne Particulate Material In Utah Valley, Douglas R. Lawson

The Lundgren impactor is used to determine the variations in time and size distributions of particulate matter in Utah Valley. Charged particle X-ray fluorescence is employed in this study to determine elemental concentrations. Air samples are taken during two 24-hour periods in downtown Provo, 24 hours near U.S. Steel Corporation, Geneva Works, and 12 hours at Lindon Elementary School, and diurnal particulate variations are compared. The amounts of lead and bromine are four times greater on a weekday than on a Sunday in downtown Provo, suggesting the effect of the automobile on atmospheric particulate concentrations. Paraffin coated impaction surfaces are …

Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions, Power Output And Fuel Consumption Using Static And Dynamic Engine Test Facilities, Dwight J. Bushnell

Theses and Dissertations

America’s energy crunch— something new for a country that has been used to great affluence. America’s smog— an eye stinging, lung burning situation which the Environmental Protection Agency has "promised" to rectify. These are two outstanding problems that face the engineer and scientist of today. The end of the era of cheap gasoline has brought the beginnings of a quiet revolution to Detroit: an improvement in the efficiency, economy and emission level of the American automobile. Word has penetrated to the automotive engineers that the emissions level, fuel economy and automobile safety are the prime design considerations for the automobile …

Melchizedek, The Man And The Tradition, Ann Nicholls Madsen

Theses and Dissertations

The common elements which emerge from this study are: Melchizedek was a priest-king, ruling a small city-state and presiding over the cult. He lived among a people far advanced from the primitive. There is no consensus among scholars concerning the meaning of his name but "Sedeq (a name for God) is my King" is a possible translation. Melchizedek's city-state was named Salem and of the four plausible geographical locations postulated, the Salem-Shechem theory leaves fewer problems. Abraham and Melchizedek worshiped the same God who was known by several names, among which were 'El 'elyon, God Most High and Yahweh. All …

Chemotaxonomical Comparison Of Astragalus Megacarpus, Astragalus Beckwithii, And Astragalus Oophorus In Utah, Marzilla Wright Anderson

Theses and Dissertations

This investigation was concerned with the taxonomic relationship between Astragalus beckwithii (Torr. & Gray) var. beckwithii, Astragalus oophorus (S. Wats) var. caulescens (Jones) Jones, and Astragalus megacarpus (A. Gray). An attempt was made to relate some chemical constituents and the toxic effects on rats to the taxonomy. A number of parameters were used; rat toxicity, lipid analysis, selenium atomic absorption, various salts and glucose percentages, as well as the usual morphological measurements taken from herbarium specimens, field observations, and pollen measurements. While the weight of the data indicates that A. beckwithii is a type of intermediary or intergressory product of …

Breeding Biology And Ecology Of The Peregrine Falcon (Falco Peregrinus) In West Greenland, William A. Burnham

Theses and Dissertations

During the last twenty years marked declines in Peregrine Falcon populations have occurred in many parts of the world (Hickey, 1969). During recent years the peregrine has been placed on the list of Endangered Species. Several factors have been suggested as the cause of its decline. These include changing climatic conditions (Porter and White, 1973), human disturbance (Mattox, pers. comm.), and introduction of chlorinated hydrocarbons as pesticides into the environment (Ratcliffe, 1970). The third factor, introduction of chlorinated hydrocarbons, has occurred on the American, European and Asian continents. Even peregrines nesting in locations far from human population concentrations are exposed …

Genetics, Environment, And Subspecies Differences: The Case Of Polites Sabuleti (Lepidoptera: Hesperiidae), Arthur M. Shapiro

Great Basin Naturalist

Polites sabuleti is an example of an insect having a univoltine, monophenic high-elevation subspecies and a multivoltine lowland one that produces similar phenotypes only in cold weather. When reared under conditions that induce the warm-weather phenotype in lowland stocks, the montane subspecies P. s. tecumseh continues to produce its usual phenotype, indicating that it has become genetically fixed.

Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert

Theses and Dissertations

Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

Conifer Wood From The Upper Jurassic Of Utah; I, Xenoxylon Morrisonense Sp. Nov., William D. Tidwell, David A. Medlyn

Faculty Publications

A new species of conifer wood, Xenoxylon morrisonense, is described from the Morrison Formation on the Colorado Plateau. It is compared with other species of Xenoxylon, with X. latiporosum being the closest. Xenoxylon morrisonense differs from X. latiporosum in its marked indentations, simple pits on the horizontal and tangential walls of ray cells, absence of crassulae, presence of wood parenchyma, and thin borders on podocarpoid type crossfield pits. The origin of the septa in the tracheids is summarized, and the possible affinity of Xenoxylon with the Podocarpaceae is considered.

The Historical Development Of Wasatch Trails In Salt Lake County, Clyde Brian Hardy

Theses and Dissertations

In this study investigation was made concerning the etiology of the foot trails that thread their way through Wasatch Forest lands in Salt Lake county. The time delimitation was 1847 to 1975.

The origin of the majority of these trails dates back to the nineteenth century and is closely tied to the efforts of pioneers who labored to wrest a living from semi-arid land. Early lumbering, livestock operations, mining activities, water collection systems, and pioneer recreation all provided impetus for trail development. In a sense these trails are a kind of anthology of human endeavor.

Passing into the twentieth century …

History Of Four Mormon Landmarks In Western New York: The Joseph Smith Farm, Hill Cumorah, The Martin Harris Farm, And The Peter Whitmer, Sr., Farm, Rand H. Packer

Theses and Dissertations

As the church returned to Western New York in the early 1900s there was much prejudice against Mormonism. The twenty-four year mission of the Willard Bean family was instrumental in establishing a friendly atmosphere in the Palmyra, New York area and in regaining four historic land marks to the ownership of the Church.

It is still uncertain if the present Joseph Smith Sr., home was completed enough for the family to live in by the time the Angel Moroni visited Joseph Smith. Since 1881 the Sacred Grove was considered the woods where Joseph Smith had his First Vision. The term …

A Comparison Of Mission Programs Used In The Three Language Training Missions Of The Church Of Jesus Christ Of Latter-Day Saints, Rawn Arthur Wallgren

Theses and Dissertations

Since the instigation of the first language training mission in December, 1961, The Church of Jesus Christ of Latter-day Saints has been vitally interested in the language instruction of its missionaries. As the number of missionaries called to foreign missions increased, the need for more facilities and instruction grew rapidly. During the week of January 18, 1969, Elder Spencer W. Kimball, Chairman of the Church Missionary Committee, announced expansion of the language training mission program that would go into effect on February 8 of that same year. Languages would not only be taught at Brigham Young University, Provo, Utah, but …

The History Of The Church Of Jesus Christ Of Latter-Day Saints In South America, 1945-1960, Joel Alva Flake

Theses and Dissertations

The history of the Church of Jesus Christ of Latter-day Saints in South America between 1945 and 1960 shows growth in numbers of members and strength of those members. The church grew more than 1000 percent during those fifteen years and almost half of all South American branches came under the direction of local, native leadership. The three new missions organized were evidence of the growth being made. Church building was stepped up and Church literature in Spanish and Portuguese became plentiful.

Some problems encountered were opposition of the prevailing church, misunderstandings with government, and the inefficiency of transportation and …

For God And Country: Mormon Chaplains During World War Ii, Richard Maher

Theses and Dissertations

The Church of Jesus Christ of Latter-day Saints (Mormon) is a lay church inasmuch as it has no professionally trained ministers. Because of this, the Chaplains Corps during World War II questioned whether members of the Mormon faith could serve effectively as chaplains. The answer to the effectiveness of Mormon chaplains is found in their performance as many received high praise from their superiors.
During the Second World War, the Mormon Church provided the military services with a total of 45 chaplains, and although only 45 served, they saw duty in all theaters of war and served at such major …

An Analysis Of The Doctrinal Teachings Of President George Albert Smith, Robert K. Mcintosh

Theses and Dissertations

George Albert Smith, Eighth President of The Church of Jesus Christ of Latter-day Saints, was a General Authority during some of the most traumatic years in world history. His teachings and doctrines were practical, rather than philosophical or theoretical, and were applicable to a time when the world needed a message of hope and love. The two key ideas of his teachings were based on the two great commandments of Christ: love of God and love of neighbor. In addition, he also gave vital messages on the importance of obedience to God's laws, the character and attributes of God, the …

Basic Principles Of Orally Communicating The Gospel As Found In The Doctrine And Covenants, Reed Amussen Benson

Theses and Dissertations

In view of the large lay ministry of The Church of Jesus Christ of Latter-day Saints who are called upon to preach and teach the gospel, this study was undertaken to see if the latter-day volume of scripture, the Doctrine and Covenants, revealed basic principles associated with the oral communication of the gospel.

These principles became evident through the frequency that they were mentioned and the emphasis they received. They were (1) righteousness, in particular diligence, humility and meekness, prayer and fasting; (2) knowledge; (3) authority; (4) the right means of communicating; (5) the correct message--with the gospel, testimony, and …
