They are located in Western Utah and Eastern Nevada in Tooele and Juab Counties in Utah and white Pin County in Nevada. The reservation land area includes 111,000 acres.

The following report has been prepared as a study to aid those interested in historical or demographic information of these people and for agencies or individuals intending to become involved in …

Protein Needs Throughout The Life Cycle, Mei-You Tsai

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

In most countries in Africa and in South and East Asia the foods which are produced do not provide adequate diets, or in some areas, not enough food for the population. In most areas, it is not the severe shortage of food supplies, but inequality of food distribution and the quality of the diet as influenced by deficiencies of individual nutrients. One of the most severe deficiencies is in protein because of the poor quality and imbalanced diets due to lack of nutritional knowledge and ignorance of the special needs of large groups of people such as pregnant and lactating …

The Effect Of Chromosomal Position On Dosage Compensation And Ontogenic Expression Of The V+ Gene In D. Melanogaster, Jack E. Tobler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two manifestations of gene regulation-- dosage compensation and ontogenic regulation--were examined in normally positioned and relocated v⁺ genotypes in Drosophila melanogaster to determine the role of gene position in these control functions. Enzyme assays, used as criteria of gene activity, were performed on various genotypes containing different doses of v⁺ in normal and relocated positions in male and female flies. The results indicate that although differently positioned v⁺ genes may specify different tryptophan pyrrolase activities, they still show dosage compensation. In each case, the enzyme activity associated with each gene, either on the X, Y, or third …

Ribose 5'-Phosphate Aminotransferase Of Salmonella Typhimurium, Gulamnabi Y. Vahora

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ribose-5 '-phosphate aminotransferase, an alternate first enzyme in the purine de novo pathway, has been purified about 800-fold from Salmonella typhimurium (pur D-55 ). The enzyme is distinct from ribosylpyrophosphate-5'-phosphate amidotransferase (E C 2.4.2.14), has an approximate molecular weight of 229,000, and requires ribose-5'-phosphate, ATP and either ammonium ion, carbamyl phosphate or L-glutamine, to synthesize 5'-phosphoribosylamine (PRA). A coupled assay system, employing a S. typhimurium (pur G-310) extract as the coupling-agent source, was used to measure the enzyme. PRA production in this system was inhibited by higher ribose-5' -phosphate concentrations and longer (over 10 minutes) incubation periods. It …

Effects Of Dmso And Propham On Mitosis In Root Tips Of Secale Cereale, Max Rosequist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

DMSO (dimethyl sulfoxide) and propham (isopropyl carbanilate) were investigated to determine their effect singly and in combination on mitoses in rye (Secale cereale) root tip cells. Root tips were prepared for observation by the paraffin and aceto-carmine squash methods. Results showed DMSO caused the following abnormalities: arrested metaphases, multipolar spindles, multinucleate cells, stickiness, shortened chromosomes, and mitotic inhibition. Cells from propham treated root tips exhibited the same abnormalities as those treated with DMSO. In addition, propham treatments resulted in polyploid cells and chromosome granulation. In combination, DMSO and propham caused all the abnormalities mentioned above except polyploidy. In …

Water In Relation To The Establishment Of Chukar Partridge In Utah Deserts, James R. Messerli

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects artificial watering devices (guzzlers) have on chukar (Alectoris graeca) populations were studied in Juab County, Utah.

The effect of water was determined by a comparision of chukar populations near guzzlers with water to guzzlers without water. The closure of two guzzlers had a pronounced effect on the distribution of chukars and the number of chukars decreased significantly at the two guzzlers after their closure.

Water concentrated the chukars, therefore, influencing their activities. During the water-critical period, between 1 July and 1 October, frequent, possibly daily, trips were made to water by chukars.

Reproduction and chick survival …

Some Effects Of The Under Snow Environment On Growth And Carbohydrate Content Of Claytonia Lanceolata Pursh, Bryce D. Bennett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies were conducted in a mountain habitat to determine the effects of altered light and temperature upon the natural growth and/or carbohydrate cycles of Claytonia lanceolata during the period of winter snow cover. Treatments included natural control, light exclusion, and temperature alteration by insulation and by heating for a brief period. Monthly measurements were made of soil temperature (upper 12 cm), shoot development, soluble sugar, and soluble starch. The quantity and quality of light penetrating the snow cover was also determined.

About 0.0052% of the available visible light (400-750 nm) penetrated 70 cm of snow and 0.02% penetrated 50 cm …

The Influence Of Bulk Density On The Hydraulic Conductivity And Water Content-Matric Suction Relation Of Two Soils, Rafael B. Andrade

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of bulk density on saturated, unsaturated hydraulic conductivity, diffusivity and water content was measured on undisturbed and disturbed soil samples of Vernal sandy loam and Nibley silty clay loam. Bulk density was changed by artificially compacting the samples.

There was a very large decrease in hydraulic conductivity and diffusivity as water content decreased as has been noted by many others. For the disturbed and compacted samples of the Vernal sandy loam, the water content was higher at .33 and 1.0 bar suction than for the disturbed-uncompacted samples. The same general effect was noted for the undisturbed samples, but …

Economic Rent Values For Pheasant Hunting In Utah, Braulio Rodriguez V.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A conceptual model relating recreation resource values to the concept of economic rent was developed. The model argues that recreation sites possess both quality and location characteristics which serve as rent producing agents. Sites of better quality extract economic rents relative to those of lesser quality while those located most advantageously to user origins earn location rents relative to those more distantly located. The economic rent values are expressed by the differential use costs and recreationist activity associated with individual site usage.

A methodological procedure was developed which generates estimates of total rent values for a given site. The procedure …

Market Structure Analysis Of Fertilizer Distribution In Utah, John C. Welty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was to ascertain the contribution of various structural variables to a growing, efficient system of fertilizer distribution in the state of Utah. A questionnaire to survey the fertilizer distributors was used as a source of data. Information was obtained about structural changes in a five-year period, 1965 to 1970. A multiple regression program was used to synthesize these data to determine which variables were most significant and how much they contributed to an increase in total value of fertilizer sales. While empirical data were obtained only for structural dimensions of the industry, marketing theory was …

Investigations Into The Microbial Ecology And Limnology Of Hyrum Reservoir, In Northern Utah, Kenneth Maxwell Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of preliminary investigations was carried out to determine the factors promoting the dense, late summer waterblooms of Aphanizomenon flos-aguae in Hyrum Reservoir in northern Utah. Attempts were made to culture the Aphanizomenon in the ASM-8a medium of O'Flaherty and Phinney (J. Phycol. 6:95-97. 1970), but no growth was obtained and the algae soon lysed. Cultures were maintained, without growth, for more than four months in a lake water--lake sediment medium at 17 C under 1500 lux flourescent light.

Dissolved oxygen measurements using an in situ probe revealed the development of a sharp oxycline during the summer months; on …

The Flat Pod Rogue In Snap Beans (Phaseolus Vulgaris L.), Lynn B. Kerr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Segregation patterns of several pod shapes of Phaseolus vulgaris L. cv Tendercrop, were studied. The causes of build-up of off-type pods in a seed stock were examined as were possible means of reversing the buildup. Natural selection factors such as germination, vigor, earliness, and ease of threshing, favored the off-types. Careful, selective milling was found to be an aid to roguing in keeping stock seed as free as possible of the off-type pods.

An Evaluation Of A Self-Guided Visitor Tour At Bear River Migratory Bird Refuge, Steven J. Kohler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1967 this study was initiated to evaluate the self-guided visitor tour of Bear River Migratory Bird Refuge. A 20 page visitor information booklet and tour guide was prepared and published for distribution at the refuge, and its effectiveness in telling the refuge story was evaluated. To gain a measure of the self-guided tour in terms of quality, visitor use patterns and satisfactions were critically examined.

To gather data on visitor use of the refuge, the visiting public was directly sampled by three methods: mail questionnaires, on-site interviews and candid tower observations of groups on the tour.

Investigation Of Urolithiasis Occurring In Hatchery-Reared Trout In Utah, Ernest H. Dean Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The urolithiasis condition investigated occurred at a "hard water" hatchery in Utah after the trout were changed from a meat diet to a commercial pelleted fish feed as a sole sustaining diet in 1961. Numerous diet modifications proved unsuccessful in preventing urolithiasis at the hatchery. It was eventually determined that different commercial diets resulted in varied percentages of trout developing urolithiasis. The urolithic deposits found in the kidney tubules were amorphous and composed of calcium phosphate (apatite) and an organic matrix. Bacterial contamination of the kidneys was not an important factor in the formation of urolithiasis. Rainbow trout containing urolithic …

Ecology Of Badgers In Curlew Valley, Utah And Idaho With Emphasis On Movement And Activity Patterns, Frederick G. Lindzey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Between March, 1969 and July, 1970, 16 badgers (Taxidea taxus) were caught and fitted with radio transmitters in the southern part of Curlew Valley. The animals were followed telemetrically; seven animals contributed sufficient data from which home-range, movement and activity patterns could be discerned. The aver age annual home-range size of five females was 664 acres (± s.d. 99 .5 acres). Female home-range sizes were approximately the same within crested wheat-grass (Agropyron aristatum) and sagebrush (Artemisia tridentata) vegetation types, with greater distances traveled each night by females in the crested wheat-grass. Both home-range size and total movement were less …

Carrying Capacity Of The Key Browse Species For Moose On The North Slopes Of The Uinta Mountains, Utah, David E. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Shiras moose, Alces alces shirasi, and its winter habitat on the north slopes of the Uinta Mountains in Utah were studied from August, 1969, to July, 1971 to determine the food requirement for moose, the key browse species during the winter months, the acreage, density and utilization of the key browse species, and their carrying capacity for moose.

It was determined that an average adult moose had a daily food requirement of 19,133 kilocalories. The key browse species for moose were Salix drummondiana and S. geyeriana. These two species accounted for 92.0 and 4.7 percent respectively of …

The Effects Of Available Water Upon Populations Of Chukar Partridge On Desert Mountains Of Utah, William W. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of surface water to chukar partridges (Alectoris graeca) and the feasibility of rain-catchment devices for improving chukar habitat were studied on the Thomas and Dugway Mountain Ranges in western Utah during 1969 and 1970.

Sources of surface water were removed from one mountain range, and chukar populations on that range were compared with populations on an adjacent range with permanent sources of water.

Providing drinking water did not improve chukar productivity, survival, or availability to hunters. Although most birds concentrated around water supplies in the summer, some chukars appeared to live completely independent of any permanent …

A Procedure For Measuring Residual Rennin Activity In Whey And Curd From Freshly Coagulated Milk, Jorge Reyes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A procedure was developed for measuring residual rennin activity in curd extracts and whey. A sensitive substrate at pH 5.8 was prepared by mixing 6 grams of low-heat nonfat dry milk in 500 milliliters buffer containing 0.05 molar cacodylic acid, 0.02 molar calcium chloride, and 0.012 molar triethanolamine, and storing it at 2 degrees centigrade for 18 hours. Two milliliters of whey or curd extract were inoculated into 25 milliliters of substrate at 30 degrees centigrade. The coagulation time was measured and compared to that induced by 2 milliliters of a known rennin concentration added at the same time to …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carrots (Daucus carota L. cv. Royal Chantenay) and sweet corn (Zea mays L. cv. Iochief) were grown on the Utah State University's Greenville farm in 1969 and 1970. The soil was fumigated with Telone (a mixture of 1, 3-dichloropropene and other chlorinated hydrocarbons) at the rates of 10, 20, and 30 gal/acre and Nemagon (1, 2-dibromo-3-chloropropane) at the rates of 1, 2, and 3 gal/acre one week before planting. Samples of uniformly mature carrot roots were taken for the studies of total carotenes, β-carotene, total and reducing sugars, respiration, and ultrastructural changes; and those of sweet corn seeds for the …

Effects Of Water Quality On Physico-Chemical And Organoleptic Characteristics Of Selected Canned Fruits And Vegetables, Anita Kay Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of processing water quality, specifically calcium and magnesium salt content (0-500 mg/1) and the addition of chelating agents (0-250 mg/1 of aminopolycarboxylic acids, polyphosphates, hydroxycarboxylic acids or phytates), upon physico-chemical and organoleptic characteristics of canned Jonathan and Delicious apple slices, Montmorency cherries and Blue Lake green beans was investigated.

Physical determinations: shear values, turbidity of syrup or brine measured via light transmittance, Hunter color and color difference meter readings and internal can corrosion; chemical composition: pectin as calcium pectate, volatile reducing substances, total acidity, pigment determinations, nitrate-nitrogen values; and sensory measurements: texture, shape, flavor, aroma, color value and …

Effects Of Zinc Deficiency On Hemoglobin, Red Cell Counts, Red Cell Fragility And Circulating And Storage Levels Of Zinc, Iron And Copper In The Rat, Rekha R. Dalvi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three experiments were conducted to study the effect of zinc deficiency on hemoglobin, red cell counts, red cell fragility, storage of erythropoietic minerals in livers and circulating levels of zinc, iron and copper in the rat.

In the experiment 1, twenty weanling rats were divided into four groups. Two groups were fed zinc-deficient diet ( <0.5 ppm); and two groups, zinc-supplemented diet (50 ppm). The rats in the first and third groups were bled three times a week (bled), however the rats in remaining groups were bled once a week (non-bled). All rats received ad libitum food.

Mean food intake per day was considerably less for zinc-deficient rats than that for zinc-supplemented rats. Approximately 2 to 3 times as much food was required for each gram of body weight gained by the zinc-deficient group as by the controls.

In the experiment 2, …

Isolation And Characterization Of Autosomal Male Sterile Mutants In Drosophila Melanogaster, Lynn J. Romrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In order to study the genetic control of spermiogenesis, recessive, male-sterile, autosomal mutants of Drosophila melanogaster were induced with ethyl methanesulfonate. A total of 31 mutants were recovered, 15 of which were located on the second chromosome and 16 on the third chromosome. Eight second- and 6 third-chromosome mutants demonstrating sterility in all homozygous males were used for further analysis.

Complementation tests showed that 2 of the 8 second chromosome mutants (and none of the 6 third chromosome mutants) were noncomplementing, indicating that two of the mutants produced were alleles of the same locus. Mapping of the second chromosome mutants …

The Coalville Deer Herd In Northeastern Utah: Its Ecology And Management, Gary L. Hickman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study on the Coalville Deer Management Unit adjacent to the corner of Wyoming in Utah was to determine the condition of the deer herd in relation to its range and population characteristics.

Postseason doe-fawn ratio was 100:77, while an adjusted doe-fawn ratio accounting for the unproductive female yearling segment was 100:105. The approximate net-productivity for 1964 was 44 percent compared to 27 percent in 1965. In 1964-65, the average age-class mortality rate for the male and female segments was 45 and 35 percent respectively. Preseason and postseason sex ratios were 64:100 and 60:100 respectively.

Ecology Of The Morgan Creek And East Fork Of The Salmon River Bighorn Sheep Herds And Management Of Bighorn Sheep In Idaho, James K. Morgan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An ecological study on the Morgan Creek and the East Fork of the Salmon River, Idaho, Bighorn Sheep herds was conducted from July 1, 1966 to February 28, 1970.

The Morgan Creek population numbered about 100 animals upon termination of the study. The trend of this population was downward. The East Fork population numbered about 50 animals and the trend appeared to be stable or slightly downward.

Productivity of both herds was low. Lamb mortality was high and recruitment to the breeding herd low. Low recruitment rates coupled with hunting pressure caused a decline in the ram component of both …

The Effects And Desirability Of Utilizing Dried Whey In Selected Food Products, Katherine P. Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects and desirability of utilizing dried whey in pie crust, muffins, and beef gravies were studied using taste panel evaluations and objective testings.

In pastry the addition of whey caused significant changes. As the whey level increased to 10 percent of the flour weight, the crust became browner during baking and the shortometer recorded an increase in tenderness. The taste panel noted as whey levels increased to 10 percent and above that the color became yellow instead of creamy white; the flavor became undesirable; and pastry became less tender and flaky.

Whey significantly increased the desirability of muffins by …

A Study Of The Biology Of The Species Of Protocalliphora In The Northern Wasatch Range, Terry L. Whitworth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A total of 733 bird nests, representing 55 species from 23 habitats, was examined. Forty-nine percent of the nests of 39 bird species were infested with 16 species of Protocalliphora.

Infestation of bird nests by Protocalliphora is believed to be related to a number of factors, which are discussed. Loosely constructed nests, nests heavily saturated with feces, and nests occupied early in the season had low rates of infestation. Nests of colonial birds were more frequently infested than those of solitary birds. Nests of some birds were rarely or never infested.

Sixteen species of Protocalliphora are differentiated and their …

An Electrophysiological Study Of The Oral Plate Sensory Organs Of The Honey Bee (Apis Mellifera L.), Rodney R. Seeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The oral plate sense organs of the honey bee, Apis mellifera L., have been investigated employing an electrophysiological technique which allows simultaneous stimulation and recording.

The results of the study present evidence that the four bipolar sense cells innervating the sensory papillae on the oral surface of the hypopharynx are chemoreceptors. The sensory papillae respond to cations, glucose, water, and amino acids. Evidence for the absence of a mechanosensory cell is presented. The data concerning the sensory structures agree with the current theories of chemoreception.

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …

The Regulatory Effects Of Certain S-Triazine Compounds On The Nutritive Composition Of Seeds And Leaves Of The Pea (Pisum Sativum L.) And Sweet Corn (Zea Mays L.) And Responses Of Metabolic Systems, Ming-Tsung Wu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
