A Study Of The Effects Of Mastitic Milk On The Quality And Yield Of Cheese, Clayton Shirl Huber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mastitis is found to some degree all over the world where cows are used for milk production. It could be classed as one of the most perplexing problems of milk production in the airy industry. The loss to the producer and the manufacturer is of considerable importance.

Today sub-clinical mastitis is probably the most common form. This type of infection is commonly so mild that it passes without recognition. It will be investigated in this study.

The influence of mastitis on milk composition has not been studied extensively. Very little research has been done on the influence of mastitic milk …

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 …

Effects Of Beaver On Stream Flow And Water Quality, James W. Bates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water, one of the major resources of the western lands, controls the economy and expansion of the communities. Industry, agriculture, timber, livestock, game and home water needs are all dependent upon a steady and continued flow of water from wells, springs, and rivers. Water is derived from one source, precipitation, which occurs in the form of rain and snow. Watersheds which are properly managed accumulate a substantial snow pack during the winter which is the life-giving source of water for our springs.

The Utah Water and Power Report (1948) indicates the annual precipitation over the entire state of Utah averaged …

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.

Abundance, Movements, Harvest, And Survival Of Brown Trout And Mountain Whitefish In A Section Of Logan River, Utah, David W. Bridges

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Comprehensive population studies in the field of fisheries are in great demand. Many of our fishable waters are being changed, and we need to be able to predict the results of these habitat alterations. We must know how to include beneficial modifications in readjustments of habitat in order to create a fishery or prevent destruction of an existing one.

The acceptable situations for good fish production in large mountain streams are not well-known. A fishery can be properly managed only if the manager has sufficient knowledge of the carrying capacity of the habitat, the survival and mortality of the population, …

The Effects Of Cooking Temperature And Stage Of Doneness On Some Factors In Broiled Beef, Carmencita Salvosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Broiling is cooking tender cuts of meat by radiant heat from hot coals, a gas flame, or an electric element. Steaks and chops for broiling are from 1 to 2 inches thick.

Broiling as a method of cooking mat is not new, but the directions for the process are the result of individual trial and error testing and are often in conflict. Current interest in indoor and outdoor broiling, particularly in Western United States, emphasizes the need for better information. There is no measuring device for surface heat during broiling and thus little research on the relationship of surface temperature, …

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 …

Nitrite Reactions In Soil, John Otto Reuss

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Losses of soil nitrogen that cannot be attributed to leaching or crop removal have been observed in many field experiments. Several mechanisms have been proposed to account for these losses.

An Ecological Study Of The Bear Lake Littoral Zone, Utah-Idaho, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past, several projects have been conducted at Bear Lake, Utah-Idaho, by the Utah State University through the Wildlife Resources Department, in conjunction with the Utah and Idaho fish and game departments, the Fish and Wildlife Service , and the National Science Foundation. These projects have dealt primarily with limnology, limnological techniques, fish life histories, fish movements, and bottom fauna in the pelagic and benthic areas of the lake. Subsequently, a littoral zone project was set up to study some of the ecological aspects of the shallow waters of Bear Lake, and some of the influences that this area …

Some Agronomic Aspects Of Seed Chalcid Bruchophagus Roddi Gussakovsii Resistance In Alfalfas, James H. Thomas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous studies have indicated that certain alfalfa varieties and clones are more resistant than others to alfalfa seed chalcid damage. This resistance varies in all cases and data on infestations indicate that agronomic characteristics may be responsible for some of the apparent resistance. Since this is a major pest in alfalfa seed producing areas, and cultural and chemical controls have been essentially ineffective, it was decided to determine if resistance was associated with certain pod characteristics in order to find a partial solution to the problem.

The Nitrification Of Ammonium Sulfate In Polyethylene Bags In The Field And Laboratory, Carlos Dean Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many advantages and some disadvantages associated with the fall application of nitrogen fertilizers. The advantages of applying fertilizer at this time appear very convincing. It is easier to get onto the land in the fall. During the fall, farmers usually have more time to apply fertilizer than they do in the spring. In the fall the fertilizer companies offer better services. This is because the fall application of fertilizer lengthens out their season, thus making it possible for them to handle more fertilizer.

The main disadvantage is the fact that it is possible to lose the fall-applied nitrogen …

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.

The Entomological Aspects Of Seed Chalcid Bruchophagus Roddi Gussakovsii Resistance In Alfalfas, Wayne A. Rowley

Biology

The alfalfa seed chalcid has been recognized as an important pest of alfalfa seed since 1891 (Urbahns, 1920). Heavy concentrations of seed chalcid in the alfalfa seed producing regions of the western United States pose a serious threat to the production of alfalfa seed. Experiments designed to study bionomics and plant resistance of this pest are part of a regional project at the Experiment Stations of many western universities. Several states and workers are testing a number of chemicals for possible use in controlling the alfalfa seed chalcid.

Biology And Control Of The Rose Stem Girdler, Agrilus Rubicola Communis Obenb., On Raspberry, Nuggehalli N. Raghuvir

Biology

The first red raspberries were cultivated in Europe 400 years ago. They were grown for the first time in the United States some time before 1800 (Gourley and Howlett, 1941). The cultivation of raspberries is limited largely to the northern part of the United States, chiefly in the cool, temperate areas. Areas from which extensive quantities of red raspberry are shipped are located in southern New Jersey, in the Hudson river valley, in western Michigan, in the Puyallup valley of Washington, and near Sebastopol, Washington.

A Study Of The Relationship Of Potassium Accumulation To Metabolism In A Sodium Rich Yeast, Thomas H. Strunk

Biology

Physiological phenomena such as glandular secretion, intestinal and tubular absorption, nervous activity and bioelectric potentials are all closely related to the movement of sodium (Na) and potassium (K) across cell membranes. The movement of the ionic forms of Na and K across biological membranes has been of special interest to investigators because the movements fail to conform to the predictions of diffusion and thermodynamic law (35). This behavior has been referred to as active transport when the following conditions are met: i) the transport exceeds or is opposite to that to be expected from electrochemical gradients; ii) the transport depends …

Phenotypic Expression And Genetic Analysis Of A New Drosophila Melanogaster Mutant (Eyes-Reduced) Exhibiting A Structural Eye Abnormality, James W. Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959), some flies from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Phenotypically the flies of this new stock resembled the established fourth chromosome eyeless mutants of D. melanogaster, and the new mutant was tentatively designated as eyeless-prime (ey'). Turner described the morphology of ey', and he also superficially investigated the genetic basis of the trait. The purpose of this investigation was to locate the genes associated with …

Genetic And Physiological Mechanisms Associated With Certain Eye Mutants In Drosophila Melanogaster, Afton M. Hansen

Biology

A large number of flies expressing an eye abnormality was observed during the sunmer of 1960 in a "wild" Cockaponsett stock. A review of environmental conditions showed that the temperature had risen to 30 C on several days before the abnormal eyes were detected. Some of the abnormalities resembled certain expressions of known mutants such as lobe and tumorous head. Lobe eyes are reduced and flattened anteriorly, whereas the new abnormal eye is not usually reduced, but is flattened ventrally. The tumorous head phenotype is characterized by abnormal growths in the entire head region, but the new abnormality is usually …

The Price Of Prejudice, Leonard J. Arrington

Faculty Honor Lectures

When the Japanese attacked Pearl Harbor December 7,1941, about 127,000 persons of Japanese descent were living in the United States, of whom more than 112,000 were on the Pacific Coast. These could be conveniently divided into three groups: the Issei or immigrants born in Japan; the Nisei or American-born, American-educated children of the Issei;' and the Kibei, who were born in America but received some of their education in Japan.

Permanently excluded from becoming American citizens by United States law, and seriously limited in their ability to acquire agricultural and residential property by alien land laws, the 40,000 Issei had …
