Influence Of Temperature On Protein, Moisture And Fat And Some Other Factors In Charcoal Broiled Meats, Ilene C. Savage

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the increasing popularity of outdoor cooking of meat, there is interest in determining the chemical and physical changes that occur during the charcoal broiling process. Of particular interest is the effect of these changes upon the quality of the broiled meat. Although broiling is not a new method of cooking meat, a review of the literature revealed few reports of scientific work on broiled meats. Some work has been done on the effect of different cooking methods on weight losses, tenderness, palatability, thiamine, protein content, but no reports were found relating surface temperature and cooking time to rate …

Studies On The Relationship Of Serum Lipids And Dietary Intake Of Fat In Senior Citizens, Lina Wu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A number of research studies have shown that aging is a continuous and cumulative process of biological changes which frequently result in cardiovascular diseases in the older age group. Degenerative diseases of old age such as atherosclerosis and coronary artery diseases appear to be related to abnormal lipid metabolism. The findings which indicate serum cholesterol values rise with age are by no means unanimous. The combined evidence in the literature points out that serum cholesterol of newborn infants is low, then rises steadily with age in both sexes from adolescence through middle age with a higher value in males than …

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 …

Effects Of Pre- And Post-Harvest Applications Of 6-Furfurylaminopurine And N6-Benzyladenine On Physio-Chemical Changes In Lettuce (Lactuca Sativa L.), Hussein Ibrahim El-Mansy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The extent and nature of physio-chemical changes that take place in detached leaves after harvest and during storage have been reviewed and discussed by Osborne (1962) and Rogers (1955). These changes include loss of moisture (Wittwer et al., 1962), chlorophyll degredation (Person et al., 1957), Protein loss (Thimann and Manmahan, 1960), and result in subsequent appearance of the visual manifestations of senescence of plant tissues.

As lettuce, like most leafy vegetables, deteriorates rapidly and steadily after harvest. Loss of quality is inevitable and can only be minimized by rapid handling and with the best possible storage conditions (Pratt …

Effects Of Hydro-Cooling, Chemicals, And Packaging Treatments On Refrigerated-Life And Quality Of Sweet Cherries And In Vitro Effects Of Chemicals On Selected Fungi Responsible For Fruit Deterioration, Joseph Yungsheng Do

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the population tends to urbanize, the potential consumer market of fresh produce becomes distant from the producing farm. This distance brings to growers and handlers the problems of how to keep their fresh products unspoiled after harvest and during transit period of shipping, and how they can be delivered to the specified destination without substantial deterioration. It is the common interest of fruit growers, shippers, wholesalers, and retailers that the shelf-life of fresh fruit be prolonged to increase sales.

Sweet cherries are one of the important fruit crops in Utah. Being highly perishable, fresh sweet cherries have relatively short …

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 …

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).

Influence Of Sodium And Calcium Chlorides In The Nutrient Solution On Secretions Of Salt Glands Of Tamarix Species, Don L. Chadwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt glands are an adaptation for living in saline habitats possessed by several species of plants. In the family of Plumbaginaceae at least three mangrove genera, Aegialitis, Aegiceras, and Avicennia, possess salt glands according to Scholander (1962). Salt glands of the small ornamental shrubs, Statice gmelini, and Limonium latifoluim of the same family, were studied by Ruhland (1915) and Arisz (1955). Spartina townsendii of the Graminaceae and Tamarix petandra, Tamarix hispida, and Tamarix aphylla of the Tamaricaceae families also have the glands.

In Vivo And In Vitro Excystation And Description Of The Sporulated Oocysts Of Some Bovine Coccidia, Peter A. Nyberg

Biology

Excystation, as applied to the coccidia, is the mechanism by which sporozoites are released from sporocysts and oocysts. This process has been investigated both in vivo and in vitro, in poultry, rabbits, and sheep. Some work has been done with bovine coccidia, but excystation in vitro has not been reported.

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 …

Influence Of Temperature And Rate Of Heat Penetration On Some Factors In Charcoal Broiled Porterhouse Steak And Ground Beef, Geraldine Irvine

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Charcoal broiling is becoming an increasingly popular method for cooking meat. Little scientific work has been done in this area. Information presently available on charcoal broiling consists of broad generalizations which have developed from trial and error testing. With the current interest in charcoal broiling, there is a need for more factual, scientific information as to the proper procedure.

Cooking method affects palatability and nutritive value of meat. Chemical and physical changes occur during the cooking process and the reactions which take place are not fully known or understood. Each cooking method has a specific effect upon meat due to …

The Influence Of Salinity On The Growth And Reproduction Of Marsh Plants, D. K. Kaushik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The water resources of the State of Utah are rapidly being developed for agriculture and industry. They are so extensively exploited that their continued and additional use must be justified on the basis of need and efficiency of utilization. To determine more accurately the quantity and quality of water needed to operate a marsh, a project was undertaken by the Utah Department of Fish and Game, the Engineering Experiment Station and the Cooperative Wildlife Research Unit at Utah State University. The study was divided into the two phases, one on quantity and one on quality of water. The present report …

The Effect Of Range Condition And Intensity Of Grazing Upon The Daily Intake And Nutritive Value Of The Diet Of Sheep On Summer Ranges Of Northern Utah, Merwyn Mortimer Kothmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mountainous ranges of the West are commonly used during the summer and have been used in this manner since the settlement of white men over a century ago. Many of these ranges have been mis-managed and are in poor condition. The productivity of these ranges greatly affects the economy of the nation; thus, if ranges in poor condition have a nutritive value lower than ranges in good condition, it results in an economic loss. little work has been done to determine the nutritive value of mountainous summer ranges in good condition compared to similar ranges in poor condition.

Factors Influencing The Quality And Palatability Of Venison In Utah, Flora H. Bardwell

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Outdoor recreational activities dealing with the pursuit of game is exceedingly popular today and its popularity is increasing each year. Annually over 180,000 hunters go afield in Utah in search of deer. There is harvested in the state over 12,000,000 pounds of dressed venison from Utah deer herds each fall. These hunters contribute 10.5 million dollars to the economy of the state for licenses, lodging, transportation and other expense of hunting.

Deer hunting is often done by the amateur, who with little or no experience has few or improper tools or information for dressing and caring for his game, and …

Leaf Ribonuclease Activity As Related To Virus Infection, And Ribonucleic Acid Concentration, Andrew Chien-Yau Hsu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ribonucleic acid (RNA) appears to be the entity responsible for infectivity and genetic continuity in certain plant, animal and bacterial viruses. RNA also plays an important role in protein synthesis. The enzymes which are involved in RNA synthesis and degradation have received much attention. Among these enzymes ribonuclease (RNase) has been most thoroughly studied Rnase is widely distributed and has been isolated from many sources such as snake venom, bacteria, the pancreas, and many plant and animal tissues. Most studies with RNase have been concerned with its role in the hydrolysis of RNA in vitro. Therefore, it has generally been …

Biosynthesis Of Infectious Cucumber Mosaic Virus Ribonucleic Acid In A Cell-Free Medium, Men Hui Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mechanism of biosynthesis of the nucleic acids, RNA, remained obscure until 1955 when the announcement was made (14) that an enzyme isolated from bacterial sources catalyzes the synthesis of ribopolynucleotides from nucleoside-5'-diphosphates. It has been shown that the biosynthesis of polynucleotides occurs through the stepwise polymerization of nucleoside-5'-diphosphates or triphosphates. A great deal of research over the past few years has indicated that isolated nuclei from both animal (1) and plant (19) sources are able to synthesize ribonucleic acids in vitro (18).

The Biochemical Differences Associated With Iron Chlorosis In Higher Plants, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis, which is associated with a reduction in the chlorophyll content of leaves, is a major problem in the growing of deciduous fruit trees and some field crops on calcareous soil. Under various soil conditions more than one factor may be involved in the development of chlorosis in plants. A deficiency of magnesium, manganese, zinc or iron, and virus infections can induce chlorosis. It is also induced by the presence of high concentrations of phosphate, bicarbonate, manganese, copper, zinc, or numerous other factors.
