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 …

Manual Of The Flora Of The East Tintic Mountains, Utah, Glen T. Nebeker

Theses and Dissertations

The study of the East Tintic Mountains was undertaken because no extensive research concerning the plant species present has ever been done.

An Assay Chamber For Quantitative Analysis Of Nitrogen Fixation Using Intact Plants, Thomas Adrie Leslie

Theses and Dissertations

A unique assay system for quantitative analysis of biological nitrogen fixation by intact plants has been constructed and successfully tested. With the system, it has been possible to detect acetylene reduction by intact legumes in situ under laboratory conditions. This assay method is designed to approximate field conditions and in spite of possible procedural errors in sampling, background noise of the gas chromatograph and ethylene contamination of the acetylene gas used in the assay, this method is sensitive ·enough to detect as little as 1 ppm enrichment of ethylene gas as a result of acetylene reduction by intact soybean plants. …

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 …

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 …

An Investigation Of The Ecology Of Subalpine Fir On The Markagunt Plateau In Southern Utah, Ronald Beatty Bolander

Theses and Dissertations

The ecology of subalpine fir relative to broom rust was investigated. Broom rust infections were most common in trees growing on limestone soils, and seldom occurred on trees growing on basalt soils. Even though plant moisture stress was consistently higher in the plants from limestone soils, the studies indicated that moisture stress is not the major factor causing infection. The amounts of available magnesium and phosphorus were much lower in the limestone soil. It is postulated that the higher plant moisture stress of subalpine fir growing on limestone soils may aggrevate the lack of nutrients and be a contributing factor …

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 …

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; …

Commercial Bank Profits: An Analysis Of Variances In Bank Earnings From The Various Sources Of Funds, Frederick D. Delboy

Theses and Dissertations

This study examines the factors that affect the profit picture of commercial banks in the United States. Particular emphasis is placed on discovering whether or not the profits earned by commercial banks on government funds are at a great disparity with those profits earned on other sources of funds. The author concludes that banks today do appear to be making more money on government funds than on funds from individuals, partnerships, and corporations; that the latter activity is in effect the managing of liabilities by the least cost path and that government regulations do have a nullifying effect on run …

Bryan, Populism And Utah, Herbert E. Cihak

Theses and Dissertations

William Jennings Bryan exercised great political power for thirty years in America. Through his efforts the Democratic Party power base was broadened to include Jews, Negroes businessmen, and farmers. Bryan's call for political and social reform found many supporters in the State of Utah.

It is difficult to assess what actually caused William J. Bryan to lose the 1900 Presidential election in Utah. Yet, we must put to rest the conclusion that he lost solely because silver was an unimportant issue to the Utah electorate in 1900. The powerful influence of the Church of Jesus Christ of Latter-day Saints on …

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.

A Survey Of Parental Knowledge Of Asthma, Nancy Aldred O'Donnell

Theses and Dissertations

The purpose of this study was to investigate the level of parents' knowledge regarding asthma.

Twenty-five parents of children who have asthma were interviewed during their child's hospitalization for status asthmaticus. Adequate knowledge about environmental control and medication was noted in the majority of the subjects but over half were unable to explain the pathological changes which caused wheezeing. While most parents appear to have adequate knowledge of medications and environmental control on which to base their decisions about their child’s care there appears to be a need for more information regarding the pathophysiology.

A Comparison Of Acrosomal Proteinase Activity In The Male And Female Reproductive Tracts Of The Guinea Pig, Thomas Joseph Morris

Theses and Dissertations

The spermatozoon has been the subject of numerous investigations because of its remarkable specialization for locomotion and fertilization. Although the spermatozoon of the guinea pig is relatively large when compared with other mammalian spermatozoa, its small size has hidden many of the details of its structure from the light microscopist. It was not until the invention of the electron microscope that a thorough study of spermatozoon structure could be accomplished. The following anatomical description is based on the works of Fawcett and Hollenberg (1963), Fawcett (1965), and Fawcett (1970). The principle parts of the guinea pig spermatozoon are the head …

The Morphologic Changes In The Muscles Of Mastication Due To Direct Intramuscular Injection Of Lidocaine, Carbocaine, Procaine And Citanest, Kurt Elliot Friedman

Theses and Dissertations

One of the most commonly experienced symptoms in dentistry and one that is of major concern to the dentist is pain. Since pain is manifested when an environmental change occurs causing injury to responsive tissues, it is often spoken of as a protective mechanism.

Pain has been described by a variety of terms: sharp, burning, aching, cramping, dull and throbbing! (Monheim, 1969). Therefore, it is a difficult term to define. Monheim (1969) describes pain as an unpleasant sensation created by a noxious stimulus that is mediated along specific nerve pathways into the central nervous system, where it is interpreted as …
