The Use Of Amprolium In Controlling Coccidiosis In Lambs, Joseph E. Kuta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Young lambs are subject to severe infections with coccidiosis, which cause weight loss, morbidity, woolbreaking, and death (Christensen, 1940b; Shumard, 1957; Lotze, 1959; Smith et al., 1960). Dunlap et al. (1949) have shown that the adult sheep are reservoir hosts and are a constant source of infection to lambs. Outbreaks of coccidial infections, especially under feedlot conditions, are frequent (Newsom and Cross, 1931; Piras, 1934; Deem and Thorp, 1940; Mahrt and Sherrick, 1965).

Estimating Forage Production Following Pinyon-Juniper Control: A Probabilistic Approach, Terrence F. Glover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An important management practice within the 60-80 million acres of Pinyon-Juniper woodlands is to convert these woodlands to open rangelands. The success or failure of seedling adapted grasses in place of trees is contingent upon the revegetation techniques employed and upon fortuitous weather patterns. In order to formulate policy for Pinyon-Juniper control decisions, persons responsible for such policies need to know the risks of introducing range grasses into given areas. This thesis is essentially a hypothesis concerning the magnitude of such risks.

Potentiometric Measurement Of Sodium Chloride In Cheese, Seyed-Hossein Salimi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The salt content of cheese is usually determined by the American Dairy Science Association (ADSA) (26) procedure. This method is based upon the determination of chloride in the sample, and results are expressed as per cent sodium chloride. The presence of chlorides in cheese other than sodium chloride would introduce error in the results. However, in practice this is not serious except where relatively large amounts of CaCl₂ are added to the cheese milk.

In determining the NaCl in cheese, one would be as justiied in basing his results on sodium analysis as on chloride analysis. An exception would …

Breeding And Roasting Temperature As Related To Beef Tenderness And Other Quality Factors, Ruth Ann B. Jenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

According to the 1964 census the production and sale of livestock provided a major source of income in the state of Utah. Twenty-three of the state's twenty-nine counties received more than 40 percent of their total farming income from livestock sales in 1959. According to Taylor (1965) this is expected to increase even more. In studying the economic sources within Utah, it becomes evident that many of the state's farmers and ranchers depend heavily on the sale of livestock for their livelihood. Upon observing this fact, Taylor (1965) states that farm income will depend just as heavily on the sale …

A Comparison Of Tests Used In The Selection Of Milk, Roger L. Stephens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The selection of milk has for many years been based upon the use of bacteriological tests such as the standard plate count, methylene blue, and resazurin tests. Such tests demoted the numbers of bacteria in milk and thus were well accepted as a close correlation of sanitary practices on the farm.

However, improvements in equipment, cleaning procedures, sanitizers and handling methods have greatly improved milk quality over the past decade. The farm bulk tank is a much more efficient system of cooling use in many areas. However, its very efficiency in cooling milk poses many new problems for those engaged …

Sound Communication In The Uinta Ground Squirrel, Donna Mae Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Numerous investigators have studied sound communication in animals in recent years. Most of these studies have been on birds, insects, or cetaceans, particularly the dolphin. Most of the studies on terrestrial mammals have been of the natural history type, and the authors have given an orthographic rendition of any sounds produced by that particular species. Few definitive studies have been done. There have been a few attempts to determine cause and function of sounds in mammals (Arvola, lImen, and Koponen, 1962; Bartholomew and Collias, 1962; Rowell and Hinde, 1962; Andrew, 1963).

No quantitative studies on sound communication in Citellus have …

A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.

While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …

A Comparative Study Of Economic Development: Thailand And India, Charnchai Charnchayasuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quickening the rate of economic growth and the conquest of poverty are the primary expressed objects of public policy in the underdeveloped countries of the world. In the new countries, particularly in Africa and Asia which have recently become independent, it was necessary to start almost from scratch in the construction of an advanced economy. Such countries have usually had (a) a high proportion of population in agriculture, with low productivity; (b) little capital per person and crude technology; (c) major expenditures for food; (d) high birth and death rates; (e) poor health and sanitation; and (f) a low level …

Some Movements Of Black-Tailed Jackrabbits In Northern Utah, Donald H. Rusch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This work describes the extent and pattern of some black-tailed jackrabbit (Lepus californicus) movements and areas of activity in northern Utah and their relationship to sex and age, and season of the year.

Black-tailed jackrabbits are the most common lagomorphs in much of the western United States, particularly in that vegetational association described by McDougal (1908) as the sagebrush desert. Furthermore, Adams and Adams (1959) have suggested a correlation between sagebrush (Artemisia tridentata) incidence and jackrabbit density.

Farmers often regard this species as a liability because of its depredations on alfalfa (Medicago sativa), crested …

Geology Of The Monte Cristo Area, Bear River Range, Utah, Robert B. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Monte Cristo area is a 7 1/2-minute quadrangle located in the southeastern. part of the Bear River Range, northern Utah. It is within the Middle Rocky Mountain province and is 10 miles east of the Basin and Range province. Previous to this investigation little was known about the detailed geology of the area except for a reconnaissance study and general geologic map of the Cache County part included in the Geologic Atlas of Utah, Cache County, published by Williams (1958).

The purposes of this investigation were as follows: (1) to determine the formations present in the area and their …

The Programmed Text As An Aid To Teaching Spelling In Junior High School, Gordon Howard Nicholls

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Organized education, historically, has been slow to commit itself to any sort of intensive examination of how learning can be both analyzed and substantially improved. But today Komoski (1960) tells us that we are looking beyond the traditional approaches to teaching. If a newly developed method is shown to be more effective than the techniques which have traditionally been employed, it is carefully considered for incorporation into the current education program.

Programmed instruction is just such an example of a recently developed teaching method which claims it will contribute much to education. It dates back to Pressey's report (1926) of …

A Tropical Colonization Experiment In Mexico, Charles Ray Alban

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It would be almost a full year before the families would be reunited in a new and different environment.

Host-Parasite Relationships Between Prunus Mahaleb And The Parasitic Nematodes Pratylenchus Neglectus And Meloidogyne Hapla, Bernard Al Tait

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah orchardists have encountered problems which they have needed to control for continued successful and economical fruit production. Some of these problems are diseases such as western-X virus, cytospora canker (Wadley, 1955) and codling moth (Davis, 1957). These diseases, because of their nature and severity, have received more attention than others.

Effect Of Calcium Availability On Alfalfa Grown In Calcareous High Sodium Soils, Harry Irving Nightingale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil science we shall always be confronted with reactions in soils that involve Ca. Early recognition of this led to experimentation in this area. Due to the fact that Ca deficiency is most common in acid soils, the majority of the experimentation has in the past been largely confined to acid soils and their soil-Ca-plant relationships. There has been relatively little research done with Ca and its availability problems associated with alkaline or sodic soils.

Error Structure Of Randomized Design Under Background Correlation With A Missing Value, Tseng-Chi Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The analysis of variance technique is probably the most popular statistical technique used for testing hypotheses and estimating parameters. Eisenhart (12) presents two classes of problems solvable by the analysis of variance and the assumption underlying each class. Cochran (9) lists the assumptions and also discusses the consequences when these assumptions are not met. It is evident that if all the assumptions are not satisfied, the confidence placed in any result obtained in this manner is adversly affected to varying degrees according to the extent of the violation.

Venison Flavor: Study Of Volatile Compounds In Cooked Deer Meat, Praful C. Vin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Venison meat has a characteristic flavor which is acceptable if mild but some venison has a strong and objectionable flavor. The subject is of practical importance where deer is hunted as sport and for food. Each year in the State of Utah, over 180,000 hunters go in search of deer and over 130,000 animals are killed. This contributes about 10 1/2 million dollars to the economy of the state from licenses, lodging, transportation and other expenses of hunting. The problem is not only important in Utah but also in the U.S.A. and other parts of the world where venison is …

The Relationship Between Personality As Measured By The Minnesota Multiphasic Personality Inventory And Interest As Measured By The Kuder Preference Record, Robert Glen Knudsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Counselors frequently use batteries of psychological tests in helping students to select appropriate educational and occupational choices. The task of interpreting scores on a battery of tests to students is not at any time a simple undertaking. The trend toward emphasis on the importance of the relationship among the various scores in a battery of tests, has further complicated test interpretation.

Vocational choice theories suggest an interrelationship between vocational interests and personality characteristics. They further suggest that different educational majors and occupations require different types of vocational interest and personality characteristics. Two tests, The Minnesota Multiphasic Personality Inventory (hereafter referred …

An Analysis Of Parental Attitudes Toward The Instrumental Music Program In The High Schools Of Bingham County, Idaho, Clark R. Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the end of World War I instrumental music has become an important and accepted part of the secondary school curriculum (17, pp. 56-59). According to a recent report published by the American Music Conference, Chicago, Illinois (19, p. 3), there were in 1963 eleven million students studying music in the schools of America.

There have been numerous studies conducted to determine the purpose and objectives of instrumental music. Many studies have also been made to ascertain what the parents' feelings are toward their schools. Yet there has been very little research or study accomplished concerning the feelings or attitudes …

Her Hour Upon The Stage: A Study Of Anne Bracegirdle, Restoration Actress, Julie Ann Farrer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has always been for me a personal source of regret that so much dramatic art is wasted, so to speak, on the unknowing times. The performances of many actors and actresses have often been of greater creative value and artistic invention than the efforts of the playwrights themselves. Yet the annals of history preserve, for all time, the written word, while the sound and emotion of great acting is lost with its moment. Only the scant impressions of the casual playgoer survive to bring back a faded view of what glory the stage must have known when great talents …

Basic Problems In Playing The Cornet, Loyal J. West

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

After having spent a number of years in the teaching profession, the writer has become aware of the need for a study dealing with the specific and technical problems in playing the cornet.

The problems of performance on the cornet may readily be divided into three groups: (1) those having to do with the instrument, (2) those having to do with the player, and (3) those having to do with the interpretation of music. The problems of playing the cornet will be dealt with in this paper only as they apply directly to the problems of learning the instrument itself. …

A Study Of 5-Fluorouracil: Its Effects And Mode Of Action In Drosophila Melanogaster, John B. Jenkins Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations involving the fluorinated pyrimidine, 5-fluorouracil, and its effects on viruses, bacteria, plants and mammals, have brought to light the following facts: FU inhibits the growth of bacteria, plants and mammalian cells and it decreases the ability of certain viruses to produce progeny. In other words, FU is an antimetabolite that inhibits growth and/or reproduction. Two mechanisms have emerged from these studies to define the mode of action of FU. The first mechanism involves the incorporation of the compound into the RNA of the organism thus altering the base sequence and creating a non functional or damaging nucleic acid. The …

The Use Of "Fashion Therapy" As Adjunctive Therapy In The Rehabilitation Of Psychiatric Patients, Virginia Geddes Eyestone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mental illness is one of the greatest public health problems and foremost challenges of our time. However, because of improved medical practices and modern research methods, more mental patients are now being released and returned to society than at any other recorded period.

The mentally ill person loses touch with reality. Things that once were of primary concern are no longer important. Many mental patients become accustomed to carelessness in dress and personal habits. This state of deterioration often remains as a mark of mental illness, and the resulting inappropriate dress frequently limits the activity of the individual. The patient …
