Life History Notes On The Walleye, Stizostedion Vitreum Vitreum (Mitchill) In A Turbid Water, Utah Lake, Utah, Billy B. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early in 1952, walleye fry were stocked for the first time in Utah Lake. Subsequent plants were made in 1954, 1955 and 1956. Altogether, over two million fry have been stocked.

By January, 1958, it was felt sufficient time had elapsed for the species to establish patterns of growth, reproduction, food habits and consequent relationships to the new environment. Thus, on January 1, 1958, a Federal Aid to Fisheries project, number DJ F-4-R-5, job T, was initiated. This project was entitled "investigations of Yellow Pikeperch and Channel Catfish of Utah Lake, Utah County." Although the closing date was December 31, …

Interaction Of Riboflavin With Molybdenum, Jacques Tocatlian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum may function as a catalyst in promoting and controlling some of the complex chemical reactions that go on in living systems. The lack of understanding which exists about these reactions is due to their obvious complexity and to the extremely minute quantities of molybdenum involved. Traces of molybdenum have been shown to have spectacular results on the growth of plants when added to certain soils. This metal is also required for the growth of azobacter, the nitrogen-fixing bacteria (1).

Molybdenum has been shown to be present in four enzymes: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4) and aldehyde …

How The Curricula Of The Special Navajo Programs Meet The Needs Of The Students At The Intermountain School In Regard To Their Use Of Alcoholic Beverages, C. Stewart Munz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Straddling the Continental Divide, from the Chuska Mountains t o the San Juan and Little Colorado rivers, mostly in Arizona, but partly in New Mexico and Utah, lies 23,574 square miles of desert; home to the estimated 75 to 90 thousand Navajo Indians. Unable to more than eke out a bare existence in a barren land where almost 30 acres of range are needed to sustain one sheep, unprepared after generations of isolation and neglect to leave this reservation for areas where a decend standard of living can be had, the Navajos, since 1950, have been the object of a …

Distribution And Movements Of Some Fishes In Bear Lake, Utah-Idaho, 1958-59, Stanley K.Y. Loo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the summer of 1958, a study of the "Population Dynamics of the Small Benthic Fishes of Bear Lake, Idaho and Utah," was sponsored in part by a National Science Foundation grant to the Wildlife Management Department of Utah State University. The study was designed to extend over a period of three years.

The Effect Of Feeding Various Levels Of Fluoride To Dairy Cattle On Their Pepsin Activity, Hassan Sabeti-Rahmati

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In certain industrial areas fluorides are present in various amounts in the atmosphere. These fluorides are liberated by industrial processes at high temperature in treatment of materials containing fluoride, either as a natural impurity, or as added material for technical purposes. Equipment and procedures have been installed in many plants to reduce the output of fluorides significantly, yet forage and hay grown near the plants may contain elevated amounts of fluorides. The feeding of such material to young livestock for many months may cause fluorosis or chronic fluoride poisoning. Some springs contain a high concentration of fluorides and the continuous …

Fluctuations Of The Clover Seed Chalcid, Bruchophagus Gibbus (Boh.), And Other Alfalfa Insect Populations In Cache Valley, Utah During The Summer Of 1958, Keith C. Tilley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The clover seed chalcid Bruchophagus gibbus (Boham) as it is presently classified, was originally described by Howard, in 1879 as Eurytoma funebris Howard (Comstock 1880). Kolobova (1950) reported different races of chalcid on clover and alfalfa in Russia. Studies are presently being conducted in the United States to see if these are applicable to our fauna, Burks (1960).

Effects Of Beta Rays, Gamma Rays, And Hydrochloric Acid On Tubers Of Jerusalem Artichoke, Subhi Al-Sammarai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Levulose (D-fructose, fruit sugar), C₆H₁₂O₆ is a white crystalline ketohexose. This sugar has distinctive properties which make it of commercial interest. It is more costly than ordinary table sugar (sucrose). Levulose is characterized by a high degree of sweetness (6), great solubility (20), and medical usefulness when administered intravenously. Joslin (21) and Root and Baker (32) found levulose to be of great value in the treatment of diabetes. According to Daniel (8), it is assimilated and oxidized more quickly than sucrose, supplying the necessary energy requirements for the human system. Additional uses of levulose have …

Descriptions, Biology, And Notes On The Identification Of Some Trogoderma Larvae, R. S. Beal Jr.

Ba

For several years members of the dermestid beetle genus Trogoderma have attracted widespread attention, particularly since T. granariurn Everts, the khapra beetle, became established as an introduced pest in Arizona, California, Mexico, and New Mexico. This species has been the object of a control program to remove it as a hazard to stored grain and to prevent its spread to parts of the country where it is not known to occur. Species of Trogoderma other than the khapra beetle may also build up to damaging numbers in stored products. Information has been obtained on these species, as well as on …

A Morphological Description Of The Trichomonad Found In The Stomach Of Swine, Floyd M. Caskey

Biology

As far as is known, no morphological study of the stomach trichomonads of swine has been made. The majority of investigators have assumed that the trichomonads found in the cecum and stomach are identical. It has been reported that the nasal form is different from that of the cecum and that the nasal form is simlar to Trichomonas foetus. The relationships among the trichomonads from these three locations have yet to be determined.

Investigations In The Genus Chrysothamnus, Loran C. Anderson

Biology

The genus Chrysothamnus has long been noted for the great variation within its limits. More than eighty species have been technically described in this genus. In the nauseosus species complex as many as thirty-eight species have been named. An excellent morphological study of the group brought about the reduction of the number of recognized species to twelve with forty subspecies. In C. nauseosus variation has been so expressed by Hall: Nothing can be more certain than that these forty-two attemps to recognize species and varieties do not by any means exhaust the resources of the group. Every autumnal excursion into …

Studies Of Ultraviolet Inactivation Of Cucumber Mosaic Virus In Vivo, Twila Elaine Cheney

Biology

It has been known for some time that plant viruses are inactivated in vitro by ultraviolet (UV) irradiation (Arthur and Newell, 1929). The studies of Hollaender and Duggar (1936) and Price and Gowen (1937) have shown that tobacco mosaic virus (TMV) is inactivated in vitro according to a simple exponential law suggestive of a "one hit" process. More recently plant viruses have been inactivated in vivo by UV irradiation. Bawden and Kleczkowski (1955) found that the development of virus-induced lesions on French bean leaves could be wholly or partially inhibited by UV irradiation subsequent to inoculation with Rothamsted tobacco necrosis …

Comparison Of The Influence Of 17-Hydrocortisone And 2-Methyl 9a-Fluorohydrocortisone Acetate On The Involution Of The Thymus Gland In Mice, Gerald K. Wallace

Biology

Previous studies have shown that the adrenal cortical hormones play an important part in lymphatic tissues physiology. Several authors have demonstrated alterations in blood leukocytes and decreased thymus weight following administration of extracts or purified preparations of adrenal cortical hormones. For this reason the thymus gland weight and lymphocyte response have been used as a method of determining activity of several of the corticoids.

The Influence Of An Artificial Medium Upon The Morphology Of Swine Cecal Trichomonads, Charles P. Hibler

Biology

As yet no thorough studies of the trichomonads living in the cecum of swine have been made. In fresh preparations the trichomonads from the nose, stomach, and cecum appear distinct. After a period of cultivation In an artificial medium, however, the flagellates from the cecum became morphologically similar to the cultured porcine nasal and stomach trichomonads. The cultivation of the trichomonads from the cecum apparently results in either a morphological change in the trichomonad or in a selection among different species or types present in the cecum.

The Effect Of Copper And Iron Salts On The Expression Of Eye Abnormalities And Melanotic Tumors In Different Stocks Of Drosophila Melanogaster, J. Howard Turner

Biology

Phenotypes in Drosophila can be altered by subjecting the developing larvae to environments containing an exess of heavy metal salts (34, 36). Such alterations, which resemble the effects of mutant genes but are not inherited, have been called phenocopies. The mechanism through which the phenocopy is produced may suggest a process through which a mutant gene influences a phenotype. In cases where such parallels are drawn, it is assumed that a mutant gene and an environmental agent have a similar effect on a particular step in an established metabolic pathway. It would seem less likely but not impossible for the …
