Blood Oxygen Capacity Of Birds, J. R. Powell

Master's Theses

Avian blood oxygen capacity (BOC: Vol. %) was measured by a modified Roughton - Scholander syringe method with regard to parameters of body weight and sex. Two samples, collected from the Richmond vicinity, were investigated: the domestic pigeon (Columba livia Gmelin) and 25 other bird species.

A Study Of Diets Low In Phenylalanine And Tyrosine For Collagen Disease, Eva H. Crites

Loma Linda University Electronic Theses, Dissertations & Projects

In 1957, Nishimura 74 made a startling proposition that linked collagen disease with hereditary metabolic defects. This defect was stated to be in the metabolism of tyrosine. Based on this report, a pilot study was conducted in which six rheumatoid arthritis patients and one scleroderma case were treated with a low phenylalanine and tyrosine diet.

The diets supplied approximately 1500 calories and 36 grams of protein. No more than 1500 mg. combined phenylalanine and tyrosine were given in any one day. Lofenalac was used as the principle source of protein.

During the six week test period laboratory studies were carried …

Effect Of Isocaloric Unsaturated Fats On Serum Cholesterol Of Patients Treated With Hypocholesterolemic Agents, Yvonne Marie Hatley

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of a high unsaturated-low saturated fat diet on serum cholesterol levels were studied. Subjects were clinic patients receiving the following hypocholesterolmeic agents: triparanol (MER-29), diildothyroacetic acid (Diac), dextrothyroxine (d-T₄) and 3-methoxy-16, alpha-methyl-1,3,5, (10)-estratriene-16 beta, 17 beta-diol (Manvene or Anvene).

Fifteen hypercholesterolemic patients, eleven of whom were diabetic, were placed on diets with prescribed amounts of unsaturated fat. The caloric distribution was 40 per cent carbohydrate, 20 per cent protein, and 40 per cent fat. The level of unsaturated fat was 70 per cent of the total fat.

Seventy-one per cent of the patients on the hypocholesterolemic …

A Comparative Study Of The Growth Of Polyoma Virus In Two Secondary Cell Lines: Mouse Lymphoma And Normal Mouse Fibroblasts, Rheeta M. Stecker

Loma Linda University Electronic Theses, Dissertations & Projects

In comparing the growth of polyoma virus in secondary cell cultures of a mouse lymphoma (P388D₁, a known polyoma-supporting strain) and normal mouse fibroblasts (Earle’s L cells), the following observations have been made.

The L cell is capable of supporting the growth of the polyoma virus with reproduction and release of infectious particles. Viruses appear in the fluid from time to time over a period of several weeks. This probably represents a carrier state of the virus in L cells. Many of the L cells in infected cultures are not killed by the virus infection.

Virus particles released …

Classification And Distribution Of The Native Trees Of Utah, Kimball Steward Erdmann

Theses and Dissertations

This study is an attempt to consolidate the information already known about the trees of Utah and to extend our knowledge of these trees. An intensive study was made of the available literature. The tree specimens of the herbaria of the Utah State University, University of Utah, Brigham Young University and the Regional Office of the Forest Service at Ogden were examined. These studies were supplemented with extensive field work in various parts of the state. From this information, keys and descriptions of the genera and species were written and distribution maps for each tree and illustrations of many of …

Geographic Variation Of The Hispid Cotton Rat In New Mexico, A.L. Gennaro

Biology ETDs

A total of 520 cotton rats, Sigmodon hispidus, was examined to determine the kind and amount of geographic variation of these animals in New Mexico.

The distributional history of Sigmodon hispidus in New Mexico may be revealed by a relationship between color variation of these animals and soil color of areas from which these animals were taken. This relationship suggests, firstly, that Sigmodon hispidus has occupied the southern Rio Grande Valley for a longer period of time than it has areas east of the Rio Grande Valley, and secondly, that Sigmodon hispidus has only recently occupied the Deming Plain. …

Notes On The History And Philosophy Of Science, Claude C. Albritton Jr.

Journal of the Graduate Research Center

In October of 1960 a small group of geologists and philosophers met in Dallas to discuss problems related to the scope and philosophy of geology. Among the subjects considered were homotaxis and geochronometry, the classification of faults, explanation in historical geology, the principle of simplicity, the principle of uniformity, the methodology of geologic mapping, the contribution of geology to general thought, and the scope of the earth sciences. Messrs. William E. Benson of the National Science Foundation, Frederick Betz, Jr. of The Geological Society of America, James Gilluly of the U. S. Geological Survey, J.M.

A Histological Study Of The Postnatal Development Of The Bovine Testis, R. G. Fossland, A. B. Schultze

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A limited number of detailed studies on the development of the bovine testis from birth to sexual maturity have been reported. Further study of bovine testis development appears desirable to furnish additional observations and to note variations that may occur during the developmental process. Information on the process of spermatogenesis should furnish a basis for experimental work designed to promote increased spermatogenic activity in the postpubertal testis as well as for work directed toward promoting complete spermatogenesis at an earlier than usual age. This report is a study of the histological picture of the testes from 56 bulls varying from …

The Life Cycle And Pathogenicity Of Eimeria Auburnensis, Wayne Norris Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coccidiosis in cattle is caused by microscopic one-celled sporozoa belonging to the order Coccidia and the genus Eimeria. Coccidiosis is a common disease of young calves that weakens or kills them, but the disease also occurs in older animals. Eleven species have been reported in cattle of the U.S.A.(Davis and Bowman, 1956). Of this number only two species, Eimeria bovis(Hammond et al., 1946) and Eimeria zurnii(Davis and Bowman, 1957) have been proven pathogenic for cattle, but except for Eimeria alabamensis(Davis et al., 1955) no experimental work has been done on other species.

An Introduction To The Ethology Of The Uinta Ground Squirrel (Citellus Armatus), David F. Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study describes behavior of the Uinta ground squirrel (Citellus armatus) in a free-living population. Its objective is to provide basic behavioral information on a small mammal which can fill in part of the gaps in our knowledge of behavior and social organization of the vertebrates. This would contribute to the long-term goal of viewing the progressive evolutionary changes in behavior from lower forms to man.

Essential Amino Acid Composition Of A Balanced Chick Diet, Donald Christensen Dobson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The scientific balancing of diets has resulted in a series of studies to determine a standard for amino acid adequacy of a chick ration. These studies have shown that some amino acids are required in a chick diet more than others; they are termed "essential amino acids". Proteins used in formulating rations vary widely in essential amino acid content. Because of this variation, it can no longer be said that a diet with so much protein (N x 6.25) is adequate to meet the chick's need for optimum performance. Many papers have been published showing the results of experiments for …

Studies On The Relationship Of The Redside Shiner (Richardsonius Balteatus) And The Longnose Sucker (Catostomus Catostomus) To The Cutthroat Trout (Salmo Clarki) Popluation In Yellowstone Lake, Kenneth E. Biesinger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biologists have been concerned about the presence of longnose suckers (Catostomus catostomus) and redside shiners (Richarsonius balteatus)and their effect on the cutthroat trout population in Yellowstone Lake. This investigation was made to determine the distribution and certain interactions of these species with cutthroat trout in Yellowstone Lake. The effects of the presence of lake chub (Hybopsis plumbea) and longnose dace (Rhinichtys cataractae) are considered to a lesser extent.

Deviations In Serum Proteins Associated With Eimeria Bovis Infections In Calves And Some Related Immune Reactions, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine coccidiosis is a serious threat to the economy of the cattle industry in the United States. In 1954 the United States Department of Agriculture reported that over $10,000,000 was lost annually as a result of mortality and morbidity in cattle due to this parasite (1). These losses alone amounted to more than one fourth of the total loss in cattle due to parasitism.

Studies On Venison Quality: Flavor Studies; Effect Of Methods Of Thawing, Kind And Level Of Fat, And Degree Of Doneness, Grace J. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Venison represents an important resource in this area. The average number of deer killed in Utah during hunting season of the ten-year period, 1940 to 1950, was over 50,000 animals annually according to the Utah State Fish and Game Department. For the period from 1950 to 1960 this figure has increased to over 100,000 animals. In terms of dressed weight, 100,000 animals would yield an estimated 8,000,000 pounds of meat. Neighboring states also produce large numbers of deer. This pictures venison not only as an important resource but as one rapidly increasing in importance.

Before the recent advent of locker …

The Hydrogen Peroxide Catalase Treatment Of Milk For Swiss Cheese Manufacture, Theodore Ricks Kowallis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various temperatures and concentrations of the hydrogen peroxide catalase treatment of milk were studied in an attempt to discover the optimum temperature and concentration that would destroy unfavorable organisms and yet allow favorable ones to grow. The Federal Food and Drug Administration in their November, 1959, Definitions and Standards of Cheeses and Cheese Products states that "the amount of the hydrogen peroxide solution used shall be such that the weight of the hydrogen peroxide added thereby does not exceed 0.05 percent of the weight of the milk treated." Within the maximum level allowed, it was found that in day old …

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

Economics Of Farm Flock Sheep Production In Northern Utah, Bruce E. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the history of mankind, sheep have played a very important and unique part in the economies of the world. They have been a source of meat, milk, skins and fiber. They have become adapted to nearly every kind of husbandry, from nomadic types to intensively managed flocks on small farms and have thrived under nearly all climatic conditions, ranging from sub-artic regions of Greenland to hot areas of the Mediterranean countries; from desert areas of Africa to wet lowland of England.
