Fluoroorganic Compounds In Relation To Hydrogen Fluoride Exposures In Leaves Of Glycine Max Merr., Julie Ye-O Cheng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soybean plants were fumigated in HF and the organic acid-fractions of the leaf extracts were compared to those of the leaf extracts from soybean plants grown in nutrient solution containing fluoroacetate. The extracts from both treatments contained fluoroorganic compounds that were chromatographically similar to fluoroacetate and fluorocitrate.

The fluorocitrate separated from HF fumigated leaves was found to inhibit aconitase prepared from pig-heart. This inhibition was similar to that caused by commercial fluorocitrate and the fluorocitrate synthesized using guinea-pig kidney. The aconitase from soybean leaves was found to be sensitive to fluorocitrate as the aconitase that isolated from pig-heart. Inorganic fluoride …

Alkali Liberated Phenolic Acids From Alfalfa, Leslie Huey-Seng Huang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fourteen compounds were isolated from an alkaline hydrolyzed extract of alfalfa leaves by using cellulose thin layer plates. The R_f values, fluorescent characteristics, and color reactions were given for all the compounds isolated.

Eight of these were identified as trans-ferulic acid, trans-p-coumaric acid, trans-caffeic acid, o-coumaric acid, tricin, syringic acid, cis-ferulic acid and cis-p-coumaric acid. The identity of the compounds was confirmed by comparison of the R_f values on thin layer chromatograms, fluorescent characteristics under ultraviolet light, and color reactions of spray reagents with those of authentic samples. Three of …

Seed Size As Related To The Selection Of Alfalfas Resistant To The Seed Chalcid Bruchophagus Roddi, L. S. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several studies have been made by others to try to find a better method of selecting alfalfa that is resistant to seed injury by the alfalfa seed chalcid. This study investigated the possibility of using seed size as a basis of selection for resistance.

Data in this thesis show that the stage of seed development when chalcid oviposited in the seeds did affect the size of seeds. Larger seeds were infested when alfalfa seed chalcid were introduced early in the development of seeds (five days after pollination), and the total number of seeds produced was slightly greater when chalcids were …

Implications Of Absentee Courtships, William Rolfe Kerr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In our society today the progress of many courtships and engagements is interrupted by separations of varying periods of time and for various reasons. Hill (1949) found that wartime family separations cause a two-dimensional crisis constituting a hazard to the continuance of the relationship both at the time of separation and at the time of reunion. The assumption is made that a courtship would be affected in a similar way. Blood (1963, p. 161) says,

Both partners change somewhat while they are apart. This is not due to the separation alone, however, for personality changes go on constantly. When people …

The Comparative Costs Of Processing Frozen Sour Cherries, Utah County, Utah, 1964, Richard K. Hart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since 1905 when Professor Henry C. Taylor opened the area of economies of scale for discussion with his observations on the variables affecting farm size, agricultural economists have been concerned with scale of plant in agriculture. Considerable study and discussion have not resolved many of the questions raised in this area, but a basic framework has been constructed which can be used as a planning tool in the efficient organization and operation of plants of various sizes under given conditions.

Transfer Restrictions And Misallocation Of Irrigation Water, Herbert H. Fullerton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water is among the most abundant of all materials known to man. In all its various forms, water covers 75 percent of the earth's surface. It is estimated that the total physical quantity of water on the earth is 326,000,000 cubic miles. This apparent abundance belies the true nature of the water resource as it relates to the needs of man. At any given point in time, only a rather minute portion of this vast quantity of water is found in those forms and locations which render it useful to man. This may be attributed to the fact that utility …

A History And Economic Analysis Of The Hyrum Reclamation Project, Douglas Eldon Brinley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Reclamation Ac t of 1902 was sign ed into law under the hand of President Theodore Roosevelt on June 17 of that year, culminating years of efforts to involve the federal government in reclamation projects. Prior to this Congress had enacted a variety of land laws designed to encourage private enterprise to develop the land and water resources of the nation, but had resisted using federal funds to construct reclamation works. The early land laws, however, served only as a temporary satisfaction to Western settlers, and Congress finally yielded to the pressure for assistance.

Use, Payment, And Knowledge Of Retail Credit Transactions By A Selected Group Of Single High School Senior Girls, Shirley Ann Lindsay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the end of World War II the Importance of the teen-age market has steadily grown. An article by Grace and Fred Hechinqer (10) In the 1961 New York Times Magazine substantiates this statement: "the young slowly are capturing an ever-growing share of the nation's market, both through their own purchasing power, and through effective dictation to parents."

A Study Of The Extent Of Extramural Competition For Girls In The High Schools Of Utah, Betty Ann Dance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Physical education is included as a part of the curriculum in most secondary schools throughout the United States. Since it is usually required for at least one year, and possibly more in some schools, it is important to design the program properly. A well-rounded physical education program is established to include three phases: the instructional phase, the intramural phase, and the extramural phase.

The Content Of Preschool Children's Original Stories, Danae Elaine Dana

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The early years of childhood are characterized by new ideas; experimentation; the building of relationships; fears, both real and imagined; and play, through which the child tries to assemble these experiences into a meaningful whole. The early years are an exciting, complex and vibrant time of learning while the child grows in his understanding of himself and the world around him.

Adolescent Attitudes Toward The Employment Of Women, Ann Leigh Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The past twenty-five years has brought about a substantial increase in the number of American women participating in the labor force. In 1940, approximately 12.8 million women were involved in employment outside the home; this was 25 percent of the total female population 14 years of age and over. By 1964, the number of employed women had doubled; there were then 25.8 million women workers. Out-of-the-home employment was actively engaging 37 percent of American women (7, p. 301). However, not only has there been an increase in the number of workers; there are also changes in the percent of women …

The Preschool Child's Concept Of God, Linda Thompson Saxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The setting is a cheerful nursery school room bustling with activity and lively three and four year old children. Sally, Tom, and Dick are building with blocks and are busily engaged in conversation regarding who is "boss" of the project.

"I'm the boss," states Sally emphatically.

''No, I'm the boss." retorts Dick with just as much enthusiasm.

"Did you know that God is boss of the whole world?" questions Tom thoughtfully. So we see one more example of the tremendous task of reaching for and of gathering in facts and experiences in the environment in order to create some semblance …

A Study Of Adolescents' Reactions To Temporary Absences From Home In A Crisis Situation, Imogene Ward Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is a description of the reactions of adolescents, who had opportunities for independence and growth toward maturity as a result of a crisis situation.

Special consideration is given to (a) the variety of heroic and realistic experiences had during the flood; (b) personal and social adjustments in the unique setting of dormitory living (separated from families); and (c) the academic achievements in the emergency learning situation.

A Program For Hospitalized Children, Leslie Joan Bishop

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When children are hospitalized they are exposed to an unfamiliar and frequently forboding world of an efficiently run institution. They cannot, as adults do, afford to interrupt (Plant, 1962) their normal way of living and exclude the relationships, play and learning that contribute to their overall growth.

There is a general tendency for children to be treated much in the same manner that adults are when they are confined in a hospital situation. The adult (Chapman, 1956) is prepared to make this temporary adjustment because he is aware, to some extent, of the need for hospitalization and the positive consequence …

Navajo Student Food Preferences, Kathlyn L. Coffman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adapt -- “to make suitable to requirements; adjust or modify fittingly." Adaptability is a trait which has been attributed to Navajo Indians by anthropologists, educators, novelists, psychologists, artists -- in fact, by almost everyone who has had dealings with them over a period of time. Yet, to identify specific examples of their adaptability and the attempt to measure the effect upon interpersonal relations of evidences of adaptation has proved to be no easy task.

Streaming Current And Streaming Potential Induced By Water Flow Through Porous Media, Mohamed M. I. Abaza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to investigate analytically and experimentally the relationship between the rate of flow of water through porous material and the streaming current and streaming potential induced by this flow. The effect of dissolved salts in the permeating solution and the size of the soil particles was also investigated.

Results and conclusions of this study are summarized as follows:

1. A modified procedure using the appropriate delay to insure stead state conditions was used for the measurements of both streaming current and streaming potential.
2. The flow-pressure relationship was the same irrespective of the counter electro-osmosis (resulting from the streaming …

An Evaluation Of The Small Business Investment Company Program, It's History And Development, With Emphasis On The Utah Sbic Industry, J. G. Dursteler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Does the small business concern in this country have access to sufficient amounts of growth capital? For the past several years there has been much controversy concerning this question. Articles have been written both pro and con voicing opinions as to whether small businesses are being discriminated against in the acquisition of long-term loans to finance growth and business expansion. The majority of the written information on this subject appears to support the theory that too many small business firms are under-capitalized and the sources of long-term investment and growth funds are seriously limited to the small businessman. The Small …

Gonadotropic Hormone Activity In Blood And Placental Tissue Of The Bovine Early In Gestation, John E. Lunnen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Certain mammalian species have been shown to secrete extra-pituitary gonadotropins. In humans the chorionic cells of the placenta secrete a gonadotropin and in pregnant mares such a hormone is secreted by the endometrial cups. Gonadotropins of placental origin have also been observed in the rat.

A Cytological Study Of Certain Life Cycle Stage Of Eimeria Bovis, John V. Ernst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although much research has been done on the bovine coccidia little has been reported on the cytological nature of the different stages. Few descriptions of cytoplasmic structures occur in the literature. Because of the impermeability of the oocyst wall a definitive study of the nucleus in the unsporulated oocyst has not been made, nor have the nuclear changes during the two successive divisions which occur during the process of sporulation been described.

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).

Immunity To Ostertagiasis In Calves, Leo F. Lejambre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parasites are responsible for heavy economic loss to the livestock industry. The losses in cattle due to parasitism can only be roughly estimated, since many cattle do not die or become visibly sick. However, there are more subtle losses such as reduced growth rate, and decreased meat and milk production (Levine, 1961). In 1954 the U. S. Department of Agriculture published an estimate of the losses in agriculture over the 10 year period, 1942-1951. At that time, the best judgement of specialists in the Department of Agriculture placed the annual loss to parasitism in cattle at $19,026,000 of which $8,989,000 …

A Study Of The Function Of Visual Imagery, Type Of Mediator, And Associative Frequency In Induced Mediation Paradigms, Ted Christiansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bugelski and Sharlock (1952) credit McGeoch with saying that although the concept of mediation was an old one, it had generated more discussion than experimentation. Bugelski and Sharlock in commenting on McGeoch's statements had this to say, "The concept of mediation is of great potential value for the psychological analysis of learning, thinking, and insight." (Bugelski and Sharlock, 1952, p. 334) The views of Bugelski and Sharlock represent the current thinking in verbal learning circles relevant to the importance of mediation in symbolic forms of behavior. The experimental emphasis, at the present time, is upon the conditions underlying the process. …

Influence Of A Male Or Female Teacher On Sex-Role Preferences Of The Pre-School Child, Mary Jane Mecham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary function of a nursery school is to educate children, or to provide opportunities for them to learn about their environment, their relationships, and their own selves. The most crucial part of the learning situation in the nursery school is the teacher, whose task it is to promote learning through provision of a variety of experiences by means of which children can discover themselves and begin to relate to the world and to other people.

Optimum Size And Location For A Northern Utah Feed Mill, Morris Duane Whitaker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the years, Utah has enjoyed the advantage of having natural agricultural resources that favor the production of livestock. Sheep and beef cattle do well on the desert and high mountain ranges that cover much of the state, Dairy cattle and wintering beef cattle use the alfalfa and native hay along with some corn silage that is grown in the irrigated valleys. Feed grains are grown in rotation with forage crops on irrigated land and also on dry land. Before 1950, the quantities of feed grains produced had been sufficient to meet the needs of dairy, range livestock and poultry. …

A Study Of Amino Acid, Protein, Organic Acid And Carbohydrate Changes Occurring During Germination Of Peach Seeds, Lee Chao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conditions required for seed germination are different among species. Some seed of tropical and subtropical plants may germinate before the maturation of their fleshy fruit, e.g. papaya species, while seed from most deciduous trees have a period of after-ripening before germination. The after-ripening period, also referred to as rest or dormancy has also been observed in some vegetable crops and ornamental flowers.

The Impact Of Research And Development On Income And Employment In Utah, Thomas Clark Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research and development (R&D) play an increasingly important role in the economy of the United States. Total expenditures for R&D during the decade of the 1950's were greater than in the entire history of the United States previous to that time. As a percent of gross national product, R&D has grown from 0.2 percent in 1921, to 0.4 to 0.6 percent in the 1930's and 1940's, and is now more than 3 percent.¹

Much has been said of the impact that the growth of R&D has on the general economy. R&D had also had a significant economic and sociocultural …

A Historical Survey Of The Economic Development Of Mainland China, 1949-1962, Mandhatasinh A. Chauhan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chinese agriculture differs from the Western agriculture in the development and utilization of agricultural science on the fields. China has always been an agricultural country, but she failed to improve in techniques of cultivation as the time passed by. The land, prior to the Communist take-over, was owned and cultivated by individuals and the produce was sold in a free-market. Unfortunately, the Chinese government, prior to 1949, failed to bring about adequate agricultural reforms and implement economic development measures.

As a result an overwhelming proportion of the population of China is occupied on the land, the supply of which is …

Behavior Patterns Of The Adult Alfalfa Weevil In Cache Valley, Utah, J. Wanless Southwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa weevil, Hypera postica (Gyllenhal), was first found in the United States in Salt Lake City, Utah, during 1904 (Titus, 1910b). It spread form this point of original introduction and partially infested Cache Valley by 1912 (Titus, 1913).

The Economic Value Of Forage For Livestock On Public And Private Ranges In Utah, Mardell D. Topham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States Government controls about 359 million acres of land in the 11 Western States. This vast acreage produces recreation for vacationers, timber for lumbermen, water for city and rural consumption, forage for livestock and wildlife, and minerals for miners. In many cases, the users of these products are competing and are clamoring for a large share of this land. Consequently, land use is continually changing. Since 1941, the amount of timber cut has tripled, recreation has doubled, watersheds now yield a better quality of water (Clawson, 1957), forage for wildlife has increased but forage for livestock use has …

A Study Of The Extent To Which Further Consolidation Is Feasible And Desirable Within Selected County School Districts In Utah, Walter D. Talbot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under the mandator consolidation act of 1915, the county-unit school district in Utah had its beginning (10). Although, through this consolidation movement, many small school districts were combined into larger ones, the elimination of the small districts did not, necessarily, provide for the elimination of the small schools. Due to several factors including distance, poor communication and transportation facilities, and a strong desire on the part of the people who lived in small communities for a voice in school matters, the consolidation of school attendance areas did not keep pace with school district reorganization.

With the improvement of highways and …
