Groundwater Development In Arid Basins, Dean F. Peterson Jr., Harold E. Thomas, J H. Feth, P. H. Mcgauhey, James H. Milligan, Wayne D. Criddle, Judge Lewis Jones, Dallin W. Jensen, Calvin G. Clyde, Bartell C. Jensen, C. E. Jacob, Jay R. Bingham, E. O. Larson

Reports

Summary: Groundwater development frequently provides a means whereby tremendous new economic opportunities are opened up. If supplies are overdrawn (mined) the ensuing regional economy may be able to affort replacements from more costly sources. In the United States the Salt River Valley of Arizona and the valleys of California provide examples. Two cases are treated in this paper, Israel and West Pakistan. In Israel, besides furnishing more than half of the basic source of water suppply, groundwater development provides opportunity for both quantity and quality management, which makes possible use of surface supplies and reclaimed sewage as firm rather than …

Use Of Uric Acid Analysis To Evaluate Chalcid Infestation In Alfalfa Seed, Gary M. Booth

Biology

The production of alfalfa seed is a major agricultural industry in various parts of the world, including the United States. One of the most serious pests of alfalfa seed is the alfalfa seed chalcid, Bruchophagus roddi Gussakovsii. The female chalcid destroys the seed by ovipositing in young alfalfa seed that is about nine days old. The egg hatches into a white larva in about four days. During the course of larval development, it devours virtually everything in the seed. When the chalcid completes its last or fourth larval instar, the insect may follow one of two alternatives of development: (1) …

Bioassay Evaluation Of Heptachlor, Telodrin And Diazinon Using Cache Valley Populations Of The Alfalfa Weevil, Lan Lin Wu

Biology

The alfalfa weevil, Hypera postica (Gyllenhal), is an insect of European origin which by some unknown means was introduced into Utah (Titus 1910). It is the most destructive pest of alfalfa in the United States although locally others may be more serious. The female inserts her eggs into the alfalfa stems during the spring months. The larvae feed on the developing leaf buds and the leaves, often completely stripping the plants. The weevil destroys from seven to eight percent of the alfalfa in Utah each year. It costs alfalfa growers in the United States several millions of dollars in annual …

The Biology Of Euphytomima Nomiivora James (Diptera:Sarcophagidae), A Parasite Of The Alkali Bee, Nomia Melanderi Ckll., Mohammad Javad Moradeshaghi

Biology

Euphytomima nomiivora James is a sarcophagid fly belonging to the sub-family Miltogramminae . It was first found as a parasite of the alkali bee in Logan, Utah in 1947 by Dr. George E. Bohart who sent several specimens to Dr. Maurice James of Washington State University for determination. Dr. James (1955) described it as a new genus and species but noted that it had previously been collected from other localities such as Imperial County, California and Globe, Arizona. In Logan it was found at an alkali bee nesting site near the Cache-Logan Airport. Later it was introduced to an artificial …

Behavioral And Physiological Changes In House Mice Associated With Sound Deprivation, Clifford A. Meyers

Biology

The development of sensory organs for the reception of external stimuli has clearly been of importance in the evolution of animal life. In part, through natural selection, these organs have increased in complexity and efficiency to the present level seen in mammals and birds. Differences in the physical nature of the sensory stimuli facilitated the development of specifically different organs, each mode of stimulation being of some importance to the animal; yet the relative importance of these modalities depended and depends on the animal-habitat unit.

Man And His Water Resource, Dean F. Peterson

Faculty Honor Lectures

Several preceding honor lectures have dealt with water. The title of a recent one, "Water and Man," by Dr. Sterling Taylor closely resembles the one for this paper. Dr. Taylor's paper dealt primarily with the physical science of water. This one will consider the nature of the use of water by man and the technological and institutional structure related to that use. Thus there should be no serious overlap. My friends in the social sciences may be surprised, too, to find that somehow this lecture has spilled over into their territory. But engineering is the implementation of science and technology. …

Molt Patterns In The Great Basin-Pocket Mouse, Perognathus Parvus, R. Lynn Speth

Biology

Studies of the patterns and sequences of molts in rodents are too few to permit generalizations concerning the taxonomic or ecologic significance of these phenomena. Noteworthy studies of the molts of Thomomys umbrinus (Morejohn and Howard, 1956), Peromyscus boylii (Brown, 1963), Peromyscus leucopus noveboracensis (Gottschang, 1956), Microtus californicus (Ecke and Kinney, 1956), and Dicrostonyx (Hansen, 1959) have utilized live-trapped captive animals. However, most reports in the literature have been based upon the examination of prepared study skins, and these data have been summarized by Ecke and Kinney (1956) and Morejohn and Howard (1956). To date the molts and pelages of …

Chromatographic And Spectrophotometric Studies Of Sodium Yeast Metabolism, Walter M. Neville

Biology

The general problem of discovering the role of potassium (K) and sodium (Na) ions in cell metabolism and physiology has been investigated in many ways. The development by Conway and Moore (1954) of a yeast that had a reversed intracellular Na and K ion concentration opened a new approach to the investigation of Na and K effects on intermediary metabolism. This yeast with a Na and K ion reversal (i.e., a high Na and low K intracellular concentration) is called a sodium-rich yeast (Na-yeast).

Biological Studies Of The Parasites And Predators Of The Alfalfa Weevil With Particular Reference To The Effects Of Selected Insecticides, Robert R. Perkes

Biology

The alfalfa weevil Hypera postica (Gyllenhal) was first observed in the United States in 1904 on a farm in Salt Lake City, Utah (Titus, 1907). Since that time, it has spread to 40 of the states in the Union and two provinces of Canada (USDA Leaflet 368, 1965). The alfalfa weevil is recognized as the most serious pest of alfalfa in this country, and for many years has caused millions of dollars of damage to the alfalfa industry in America (Sorensen, 1934). Since the introduction of the alfalfa weevil into Utah, various methods of control have been employed to stop …

An Educational Study To Determine The Nutritional Value And Acceptability Of Dry Milk Among The Navajo, June C. Larson

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

One day at the Intermountain Indian School, when a package of government surplus dry milk seemed to defy opening, a senior Navajo student offered her assistance anx easily opened the many boxes of milk. Upon inquiry, she said that she had opened many a box, especially in the springtime. She went on to say that most of their dry milk was used in the spring to feed baby lambs.

Later this same student told how her baby sister had died during the winter from something. The sister just seemed to get sick and then died. Could her death have been …

The Complex Formation Of Silver Ion With Ribonucleic Acid, Guanosine, Inosine And Related Compounds And Peroxidase-Like Activity Of A Haemundecapeptide Prepared From Horse Heart Cytochrome C, José Angel Reinosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nucleic acids in plant and animal cells as carriers of genetic information and as protein biosynthesis agents is well recognized. It is also known that nucleic acid is a component of all viruses.

Takahashi (45) and Fraenkel-Conrat (16) demonstrated that the protein component of tobacco mosaic virus is non-infectious to the host plant, although it is identical to the original virus morphologically. The virus ribonucleic acid (RNA) alone was infectious, however.

Deoxyribonucleic acid (DNA), which is present in chromosomes, displays a very specific function. The chromosome long has been accepted as the carrier of the hereditary unit, …

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.

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.

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 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.

Nutrition In Thailand, Methee Larptavee

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

Thailand is located in souteast Asia between Burman, Laos, and Cambodia. It has a long coast line as one strip of land reaches out into the sea. It has a warm climate with much rain, especially in the south. There are 27 million people in the area of 200,000 square miles. Rice ranks number one in the Thailand diet. Next to rice is fish, both from fresh water and from the sea.

A nutritional survey was first made in Thailand in Bang Chan Village in 1952-54, in connection with the Cornell-Thailand project. Since the results covered only a small segment …

An Exploration Of Test Taking Strategy With Sixth Grade Students, Mary Bates

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

The present study was an attempt to evaluate the benefits of certain cues in reaching correct answers to test questions given to sixth grade students. While it seems reasonable to assume that test-taking strategy is not as well developed in sixth grade children as in older students, this study was intended to discover if test-taking strategy would be apparent to a measurable degree at this age level. Before such an observation could be undertaken, a technique had to be devised to measure the behavior in question (in this case the use of cues). The technique used was in the form …

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. …

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 …

Simultaneous Flow Of Heat And Water In Plant Tissue, Gaylon Sanford Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although biological phenomena may be partially described in a general way without the use of mathematics and physics, the experimental results may be more meaningful if they are analyzed on the basis of physical and mathematical laws. The complexity of biological systems has made the application to them of mathematics and physics rather difficult, and only recently has much progress been made. Although it has yet been possible to describe only a few simple biological systems by actual equations, a great deal of qualitative information may be obtained by applying physics and mathematics. Russell (1960, p. 439) said

In principle …

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 …
