Neutral 17-Ketosteroids And 17, 21-Dihydroxy-20-Ketosteroids In Urine Of University Students, Shon-Hua Yu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Degenerative disease of old age such as atherosclerosis and cerebral hemorrhage appear to be related to abnormal lipid metabolism. Many investigators have studied the role of steroid hormones on lipid and cholesterol metabolism in rats and chickens. The results have consistantly indicated that both corticosteroids and sex hormones play an important role in the regulation of lipid and cholesterol metabolism, in vivo. Serum cholesterol values in humans have been decreased by estrogens, while androgen administration tends to increase circulating cholesterol. Estrogens have been shown to decrease circulating cholesterol and prevent cholesterol-induced coronary atherosclerosis in chickens. A study of the …

Canada Goose Production And Population Stability, Ogden Bay Waterfowl Management Area, Utah, Norman H. Dey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the development of Ogden Bay Waterfowl Management Area in 1937, the Canada goose (Branta canadesis moffitti) population increased to a peak in 1949 and then declined slightly. Nelson (1954) noted that the decrease in population was probably due to either a change in habitat or increased hunting pressure. In recent years, direct band returns have indicated a high mortality rate in the population. This project was initiated to determine the relative stability of the Canada goose population and to measure, as closely as possible, the effect of a high mortality rate upon the nesting population.

Geomorphic Features And History Of The Lower Part Of Logan Canyon, Utah, Edmund J. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Logan Canyon is located east of Logan, Utah, in the Bear River Range. The lower part of Logan Canyon is considered that section of the canyon from its mouth upstream to Tony Grove Canyon, a distance of 22 miles¹, Figure 1. Some tributary canyons of the lower part of Logan Canyon have been included in this investigation because of their relationship to Logan Canyon. Grassy Flat Canyon, a south tributary of Logan Canyon 4.4 miles from Logan, exhibits several geomorphic features related to the geology of Logan Canyon. Because of its extensive use and close association with Logan …

Simulation Of Mathematical Models In Genetic Analysis, Dinesh Govindal Patel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years a new field of statistics has become of importance in many branches of experimental science. This is the Monte Carlo Method, so called because it is based on simulation of stochastic processes. By stochastic process, it is meant some possible physical process in the real world that has some random or stochastic element in its structure. This is the subject which may appropriately be called the dynamic part of statistics or the statistics of "change," in contrast with the static statistical problems which have so far been the more systematically studied. Many obvious examples of such processes …

The Interaction Of Water And Salt Flow In Unsaturated Soils, Mahmoud Hassan Abd-El Aziz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movements of salt and water, particularly in fairly dry soils or compacted shales, are important processes in both agronomic studies and hydraulics of deep ground water which is important in the location of oil.

An Economic Study Of Adjustment Possibilities In Farm Organization And Resource Allocation In The Sevier River Valley In Piute County, Utah, 1961, Gordon L. Langford

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Problems that confront the farmer are varied, but one of the most important is the combination of his possible enterprises so that maximum financial return from farming is obtained. This problem has been made more important in the last decade by the severity of the agricultural price-cost squeeze.

Farmers' total net income, on a national basis, has declined from more than 16 billion dollars to about 13 billion dollars. In Utah, total net farm income has dropped from 91.3 million dollars in 1951 to 36.5 million dollars in 1961. Average net income of Utah farm operators dropped from $5.89 per …

The Role Of The Federal Government In The Industrial Expansion Of Utah During World War Two, Anthony Thomas Cluff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For ten years the American economy had been depressed. Unemployment haunted economic planners, low production plagued manufacturers, low incomes impoverished wage earners, and everyone hoped for the dawn of new prosperity. It was as if recovery had waited for an untrodden decade to arrive before heralding the new day. The New Deal brought Social Security for old age, insurance for bank deposits, new guarantees for labor, and a score of public work projects, but it did not bring economic recovery.

Cost Of Reclaiming Pinyon-Juniper Rangeland And Its Effect On Cattle Ranch Income, John William Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There was a period during the early history of Utah when grasses in some areas grew so tall that it hid grazing cattle and sheep from view. However, mismanagement caused this to change and depleted grassland was invaded by noxious weeds, sagebrush, and pinyon-juniper. This deterioration of choice grassland to less desirable range cover was aided by the attitude of stockmen that pasture was available on a first come first serve basis. As a result of such an attitude and the unsatisfactory condition of ranges, the era of free, uncontrolled use of grazing lands came to a close with the …

Molybdenum-L-Histidine Complexes, Jiing-Yun Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

L- Histidine is a very important amino acid and is widely distributed in living systems. In the growth and multiplication of animal cells, it was found that L-histidine is one of the amino acids that must be present. From the kinetic studies of certain enzymes such as chymotrypsin and ribonuclease, it has been proposed that the imidazolyl group of the histidine residue may serve as the basic electron donor, and that the histidine residue in some cases may be the active site of the enzyme. The interactions of L-histidine with heavy metal ions, including Ni (II) (1), Zn (II) (1, …

Studies Of The Incorporation Of 5-Fluorouracil Into Tobacco Mosaic Viral Rna By Cell-Free Synthesing Systems Isolated From Infected Tobacco Plants, Helen Lu-Sheng Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on biosynthesis of tobacco mosaic virus (TMV) ribonucleic acid in vitro has been reported by a number of laboratories (8, 16, 17). Bonner et al. postulated that ribonucleic acid could be synthesized from nucleotides by chromatin extracted from nuclei of pea seedlings (5, 14, 22). The evidence from in vitro synthesis of viral RNA suggested that an enzyme, RNA polymerase, links the four nucleotides (ATP, UTP, CTP, GTP) with viral RNA present as a primer and magnesium ions participating as a catalyst (7, 8).

The Site Of The Immune Reaction Against Eimeria Bovis In Calves And The Demonstration Of Antibodies By Immunofluorescence, Ferron L. Andersen

Biology

In 1959 Senger et al. reported that calves which had received a small oral inoculation of Eimeria bovis oocysts were later resistant to larger challenge inoculations. In an investigation on the mechanism of this immune reaction, Hammond et al. (1959) compared the number and size of E. bovis schizonts in immunized and nonimmunized calves, but found no significant difference in the results. They conducted 3 experiments using 28 young male Holstein-Friesian calves, and killed the majority of these calves for examination 17 to 20 days after the challenge inoculation.

Changes In Serum Proteins And Other Blood Values Associated With Ostertagia Ostertagi Infection In Calves, Jerome L. Mahrt

Biology

Parasitism causes large economic losses to the livestock industry. Included in this economic loss are death to the host animal, but even more important are the losses due to illness, reduced growth rate, decreased meat, milk, egg, and wool production and, in working animals, loss of working energy (Levine, 1961). Even rough estimates of this economic loss are difficult to make. The United States Department of Agriculture (1954) published a 10 year report (1942-1951) on the annual losses due to parasitism in the United States. According to this report parasitism caused an estimated loss to livestock and poultry of $79,532,000 …

Experimental Study Of Tissue Eosinophil Transformation, Ferrell R. Campbell

Biology

An increase in the number of eosinophilic leukocytes has long been recognized as an integral part of the cellular response of the body to parenterally introduced foreign proteins. Although the function of eosinophils is poorly understood, high eosinophil counts have been associated with the antigen-antibody reactions resulting either directly or indirectly from hypersensitivity.

A Morphological And Cultural Study Of Trichomonads And Other Flagellates Of The Bovine Digestive Tract, Emron A. Jensen

Biology

The trichomonads of the bovine digestive tract are incompletely known and the taxonomy of the described species is not clear. Two species, Trichomonas enteris (Christl) and T. bovis (Pavlov and Dimitrov) from the lower digestive tract of cattle have been described, although the descriptions in both cases were not complete. A species of flagellates of the rumen has been known since 1913; it has been called a trichomonad by some authors and a monocercomonad by others.

The Responsible Exercise Of Creative Power, Carlton Culmsee

Faculty Honor Lectures

ONCE last summer we stood. near the snow-white cascade flowing over the world's largest concrete dam, Grand Coulee, which is twice as high as Niagara Falls. We were alone in the gallery with the shafts that link the turbines to the dynamos. The nearest shaft appeared to be a pillar strong enough to bear half the burdens of humanity. It seemed to stand still and serene. Examined more closely, it revealed itself as spinning with perfect smoothness. For all we could see, we were alone in the eleven miles of passages inside the dam and powerhouse, alone with a cosmic …

The Secret Of Viral Reproduction, George W. Cochran

Faculty Honor Lectures

Nucleic acid is the basis of life. There are 2 types, ribose nucleic acid (RNA) and deoxyribose nucleic acid (DNA). DNA, the material found in the chromosomes within the nuclei of the cells of most living organisms, bears the genetic code that determines all of the characteristics of a living organism. Information from the DNA of the chromosomes is carried to all parts of the cell by one type of RNA called messenger RNA. Additional specialized RNA molecules are found inside the ribosomes, tiny bodies within the protoplasm that make proteins for the cell. Still other, smaller RNA molecules, called …
