All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd-whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused …

Effect Of Added Calcium Ions On Relative Milk-Clotting Activities Of Commercial Milk Clotting Enzymes, Nuchanart Pavenayotin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effect of added calcium ions on the relative milk clotting activities of porcine pepsin, Mucor miehei protease, Endothia parasitica protease, and Mucor pusillus protease was compared with that of rennin. Skimmilk, maintained at pH 6. 3 with 0.000% to 0.030% added calcium chloride, was used as a substrate. The coagulation activity of Mucor pusillus protease appeared to be most sensitive to calcium ions, followed by Mucor rniehei protease, porcine pepsin, rennin, and Endothia parasitica protease. The clotting activities of Mucor pusillus protease were also more sensitive than rennin to added calcium ions in milk samples maintained at pH values of …

"In The Toils" Or "Onward For Zion": Images Of The Mormon Woman, 1852-1890, Gail Farr Casterline

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is to identify and discuss various popular images of the Mormon women of Utah between 1852 and 1890, the period during which the Latter-day Saints openly practiced plural marriage. The phrase "in the toils" refers to the basic image present in the minds of many Americans--that the women of the church were an oppressed, unhappy, enslaved group of individuals. This image, expressed in different ways, is found in many published writings of the period examined.

After demonstrating the presence of this "in the toils" image, this study then attempts to analyze and evaluate its significance. …

The Effects Of Herbicidal Spraying Upon A North Central Utah Blue Grouse Population, T. Barry Barnes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of herbicidal spraying upon a North Central Utah blue grouse population were studied. Baseline data were obtained in 1970 and 1971 prior to the spraying on June 2, 1972. The spraying was done to control wyethia (Wyethia amplexicaulis) and black sage (Artimesia nova) which covered 48 percent and 20 percent of the study area respectively.

No differences in blue grouse numbers occurred following spraying with 17 to 20 broods using the area in 1972 compared to 18 to 20 broods in 1971. Total population of blue grouse each year was between 90 and 104 …

An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

The Production And Prevention Of Stomach Ulcers In Rodents, Eric H. Rudrud

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rats given L-Ascorbic Acid in their drinking water prior to and during starvation did not develop severe ulceration in the glandular portion of their stomachs. Control rats which were either nontreated or given deactivated L-Ascorbic Acid developed severe stomach pathology on the starvation regimen.

The present study was based on the finding that food deprivation results in severe rumenal ulceration in rats. Given that L-AA is essential in maintaining tissue integrity and that ulcers are examples of tissue degeneration, the L-AA in large amounts could retard, or prevent, the formation of starvation induced stomach ulcers in rats.

The results show …

Extractable-Emulsifying Capacity Of Hand And Mechanically Deboned Mutton And Organoleptic Acceptability Of Various Mutton Salami Formulations, Jack Robert Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt soluble extracts from mechanically deboned mutton were significantly higher (P < .01) in pH than the extracts from the hand boned mutton. An associated trend toward greater extractability, however, was not significant. Variation in emulsifying capacity between extracts from carcass parts were highly significant yet significant variation did not occur in the emulsifying capacity of hand versus mechanically deboned mutton. A new term, extractable- emulsifying capacity is presented which incorporates the extractability and emulsifying capacity of meat extracts into one value which should more accurately estimate the contribution of a meat ingredient in forming a stable sausage emulsion.

Salami, utilizing mutton, was formulated from experimental results which indicated that up to 10 percent mutton fat and 68 percent mutton lean was acceptable to panelists. Pork was preferred to beef for use in combination with mutton as determined by panel scores, however disagreement was noted between panelists. Panelists were unable to detect flavor, moisture or texture differences between the final mutton salami and a commercial beef and pork formulation. They did however prefer the appearance of the mutton salami (P < .05).

Effects Of X-Ray Induced Achlorhdria On The Utilization Of Dietary Calcium And Iron From Different Salts By Rats, Reid Scott Holbrook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dietary calcium has been classified as one of the minerals frequently limiting in the American diet (FAO, 1962) . Bone demineralization has been observed as a result of calcium deficient diets (Salomon et al., 1972), partial gastrectomies (Eddy, 1971) and inadequate hormonal balance (Albright et al., 1948). Although bone demineralization, or osteoporosis, has been attributed to many factors, the interrelationship of gastric acidity and the utilization of dietary calcium may be a key to the etiology of osteoporosis.

Eighty weanling male albino rats were divided into eight groups. All animals had their stomachs exposed through a mid-line incision. Control rats …

Biochemical And Physiological Studies On Phytotoxicity Of Selected Pesticides And Allergens During Seed Germination Of Some Food Crops, R. R. Dalvi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Germination of mung bean, Phaseolus mungo L. , and wheat, Triticum aestivum L., seeds was used for bioassay to demonstrate the toxic effects of selected pesticides--menazon, disulfoton, and GS-14254-- and allergens-- alantolactone and usnic acid. The ability of gibberellic acid to counteract the toxic effects of these chemicals on germination and seedling growth was studied. Chemical composition of the treated and untreated seeds was made with special attention to starch and protein degradation. Effect of these toxicants on the synthesis of amylase, ATPase, and protease enzymes during germination was studied since these enzymes are synthesized de novo during germination. To …

Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spraying with the chemical herbicide 2,4-D is the most widely used method of controlling big sagebrush. Spraying is very effective in increasing forage production and generally is not poisonous to either man or animals.

Two procedures can be used to calculate the internal rate of return to big sagebrush control: standard and modified discounting. Standard discounting assumes all nonuse costs are incurred in the year of treatment, and the annual income stream is constant throughout the effective life of treatment. Modified discounting correctly assumes the nonuse cost is incurred in the period of deferment, and the income stream does not …

Modification Of Ontogenic Expression Due To Relocation Of The Ry+ Gene In Drosophila Melanogaster, Allen A. Badgett Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ry⁺ gene of Drosophila melanogaster and its associated enzyme, xanthine dehydrogenase, were employed in an analysis of the relationship between regulation and the location of a gene in the genome. Enzyme assays as an indication of gene activity were performed on genotypes containing zero, one and two doses of ry⁺ genes. Xanthine dehydrogenase activity of rosy genes in normal and relocated positions was determined during development.

The results indicate: 1) the gene ry⁺ is differentially active during ontogeny; 2) the activity during ontogeny is proportional to the number of ry⁺ genes present in the genome; …

Increasing Resistance To The Negative Effects Of Set, Paul B. Chance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two experimental studies were reported in which attempts were made to increase resistance to the negative effects of set. Set interference was measured by performance on 1) a task in which a set was experimentally induced, 2) a series of problems presumed to involve implicit sets, and 3) a test of creativity presumed to involve implicit sets.

The experimental treatments consisted of tasks which required set-breaking. An important aspect of this research was that no hints or instructions concerning sets were provided.

The findings offer modest support for the view that learning experiences can be designed which will increase resistance …

Economics Of Carry-Over Production And Increased Grazing Season Length Due To Range Fertilization, Paul W. Mccormick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper entails the economic and biological interpretation of the response of rangeland grasses to nitrogen fertilization. Six sites throughout Utah received graduated rates of fertilizer. The coefficients of the production function
Y = a + bN - cN²
were identified.

An initial production and a carry-over response were identified on sites receiving greater than ten inches of annual precipitation. Optimum fertilization rates may be identified by equating the marginal physical product to the ratio of the price of nitrogen to the price of the forage.

Forage response to nitrogen is reflected strongly in the early growth response in …
