The Distribution Of Sialic Acid In Selected Tissues And Body Fluids During The Female Reproductive Cycle, Donald Reed Jensen

Biology

An intriguing and dynamic chapter in the history of biochemical research concerns the acylated derivatives of neuraminic acid, the so- called "sialic acids." These substances have been found to occur naturally as constituents of a wide variety of mucoproteins, mucolipids, and related compounds. Because of their vast distribution throughout the animal kingdom, considerable attention has been focused on the chemical, physical, and biological properties of these acids. Attendant studies have shown the functional integrity of certain of the protein and lipid conjugates to be dependent on the presence of sialic acid residues, thereby assigning physiological importance to the acylated derivatives …

The Multiplication Of Lambda And Lambda-Dg Within Their Lysogenic Host Escherichia Coli K12, Gerald D. Elseth

Biology

Bacteriophage λ and its variant λdg, present in the prophage condition within their lysogenic host Escherichia coli K12, can be induced to vegetative multiplication by irradiation with ultraviolet light. Experiments conducted within this laboratory to determine the intra-cellular synthesis of λ and λdg after lytic induction indicate changes in concentration ratios between the two bacteriophages. This change in ratio is dependent upon the growth conditions of the bacteria and the dose of ultraviolet light used for the induction process. Further investigation into this problem is needed and was the major objective of this thesis study.

Biological Studies Of Three Species Of Cuterebra (Diptera: Cuterebridae) From Northern Utah, Charles L. Graham

Biology

Flies of the genus Cuterebra are found in the New World only. They are parasitic bots of rodents and lagomorphs as larvae and have been studied for about one and one-half centuries. During this time very little has been found out about the biology of most of the species, even hosts are still unknown for many of them.

The Genetics Of Abnormal Head Morphogenesis In Drosophila Melanogaster, With Special Reference To Eyelessness, Homoeosis, Penetrance, Asymmetry, And The "Fourth" Instar, James Wesley Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959) some files from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Edwards and Gardner (1962) designated the stock as eyes-reduced and located the major genetic factor (eyr) in the right arm of the third chromosome. The eyes-reduced stock possesses characteristics which are challenging to current theories in genetics and development; the purpose of this investigation was to thoroughly study those characteristics.

The Use Of Amprolium In Controlling Coccidiosis In Calves, Ronald Fayer

Biology

Bovine coccidiosis is an economically important disease in the United States. The Agriculture Research Service (1954) reported that the annual loss caused by coccidiosis in cattle in the United States amounts to $10,000,000. Fitzgerald (1963) found in a survey of losses of calves under 1 year of age in the west northcentral and the western United States that approximately $11,000,000 is lost yearly because of mortality and morbidity from coccidiosis.

The Search For Consensus, M. Judd Harmon

Faculty Honor Lectures

PROFESSIONAL political scientists develop a particular way of looking at the world and interpreting its events. Because of the forces which act upon us all, the view may be excessively narrow, its importance may be exaggerated, and it may be inaccurate as an interpretive device. Yet it is a key to understanding for the person who employs it. He inclines to view all public problems in its light and tends to assume that the solution of social problems is contingent upon an adequate understanding and appreciation of it.

My own view, and I make no claim to originality in expressing …

Inoculation Method And Treatments Which Increase The Sensitivity And Precision Of The Infectivity Assay Of Tobacco Mosaic Virus, Calvin Ray Lamborn

Biology

The active research in cell-free virus synthesis at this university has placed great emphasis on an improved procedure to assay virus infectivity. The conventional method used (finger inoculation) was simple, but low insensitivity and precision. Infectivity assays of plant viruses are complicated by large differences in susceptibility among local lesion hosts. Factors influencing the susceptibility are the age of the host and the environmental conditions under which the plants are grown, such as temperature, humidity, soil moisture, nutrition and lighting. Another problem is to get the virus into the host cell. The inoculation method has to cause enough injury to …

Histochemical Investigations Of The Effects Of Fluoride On Dehydrogenase Enzymes Of Pelargoniom Zonale, Clyde J. Hurst

Biology

The industrialization of the Intermountain West has brought with it the by products of industry. Of these by products, fluoride is of particular interest and importance, because of its toxicity to both plants and animals at low concentrations. There is a wide range of variation in susceptibility of different plants, but gladiolus, prune, apricot, and peach among others are very sensitive to fluoride in concentrations as low as 0.02 to 0.05 ppb (Katz, 1956).

Coccidiosis Of Cattle, Datus M. Hammod

Faculty Honor Lectures

The disease known as coccidiosis occurs in many domestic and wild animals. It is of great importance in chickens, in which coccidiosis is one of the chief causes of losses to the producer. In cattle the disease was estimated by Fitzgerald in 1962' to cause an . annual loss of $3,500,000 in calves under one year of age in the 11 western states and $7,500,000 in the seven west north-central states. In making this estimate Fitzgerald calculated that 90 percent of all calves are infected by coccidia, and that the average loss amounted to 75 cents per head on all …

Studies Related To The Control Of Anacamptodes Clivinaria (Guenée) (Lepidoptera: Geometridae), Harold W. Flake

Biology

Economic importance Anacomptodes clivinaria (Genee) is a serious pest of curlleaf mountain mahogany (Cercocarpus ledifolius) and bitterbrush (Prushia tridentata). Mountain mahogany and bitterbrush are important browse plants for wildlife and for watershed protection. In the winter, curlleaf mountain mahogany may serve as the major food source for wildlife because the leaves are retained year around (Flook, 1955). The deer and antelope winter ranges are some of the limiting factors in herd size and must be protected. Smith (1957) reported that curlleaf mountain mahogany has one of the highest percent nutrients of any winter browse plant for …

A Study Of Morphological Characteristics To Determine Sex In Prepupal Bees, Ross A. Nielsen

Biology

Many solitary bees develop through the egg and larval feeding stages in a week or two and then enter a quiescent prepupal peri od lasting through the winter months. When diapause is broken, development proceeds to the pupal stage in which sex can be determined easily. In contrast, sex differentiation is not obvious in the earlier stages. Michaelis (1900) studied the postembryonic development of the genital organs in fixed specimens of honey bee larvae (Apis mellifera Linn.). This study was extended by Zander (1900) to include larvae of the genera Vespa and Bombus. Although neither of these authors …

The Influence Of Respiration On The Movement Of Water Through Tomato Root Systems, Ward Bryce Roberson

Biology

The rate at which water moves through the root system of a plant is influenced, in some way, by the metabolic activities of the living cells which compose the tissues of the roots. This conclusion is based on the fact that water movement and metabolic activity are similarly influenced by certain chemical and environmental factors.

Molybdenum-L-Histidine Complexes, Jiing-Yun Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

L- Histidine is a very important amino acid and is widely distributed in living systems. In the growth and multiplication of animal cells, it was found that L-histidine is one of the amino acids that must be present. From the kinetic studies of certain enzymes such as chymotrypsin and ribonuclease, it has been proposed that the imidazolyl group of the histidine residue may serve as the basic electron donor, and that the histidine residue in some cases may be the active site of the enzyme. The interactions of L-histidine with heavy metal ions, including Ni (II) (1), Zn (II) (1, …

A History Of Timber Resource Use In The Development Of Cache Valley, Utah, Douglas M. Bird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has long been realized that the forests and forest products contributed very significantly toward the economic development of the Western United States. However, the extent of this contribution over a relatively small area has never been fully analyzed. Therein lies the primary justification for this paper. The author hopes that the readers of this paper will, through their reading, gain some appreciation of the major role the forest and its products played in the development of the western community.

Because of some important social differences between the area described in this paper and other western communities, the history herein …

On The Behavioral Responses Of Free Uinta Ground Squirrels To Trapping, David F. Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biologists often trap animals to obtain information on them. If trapping is selective toward some animals, the information may be inaccurate. Most mammalogists know or suspect that their trapping techniques (reviewed by Hayne, 1949; and Stickel, 1954) contain sources of bias. Since trapping remains the only feasible way to obtain information on many animals, researchers have tried to discover sources of sampling error and refine their techniques. They have found that one major source of difficulty may lie in the behavior of animals. Individual animals seem to respond differently to trapping, both initially and through learning (Geis, 1955; Crowcroft and …

Some Effects Of Accumulated Radium On The Productivity Of Algae, Joseph W. Angelovic

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ionizing radiation from natural occurring radionuclides and cosmic rays has always been a part of man's environment, but at such low levels as to have had virtually no effect. However, with the advent of the atomic age and the advancement of nuclear technology, background activity has measurably increased all over the world. Fallout from nuclear weapons testing, wastes from nuclear reactors, and wastes from the milling of radioactive ores have all contributed to this increase. Due to this increase, many ecosystems and their individual components are now subjected to radiation levels as high as a million times natural background. What …

Simplified Approach To The Problem Of Stability Of Soil Slopes Under Horizontal Earthquake And Pore Pressure, Dalim Kumar Majumdar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A problem that has confronted engineers for a great number of years is that of determining the stability of soil slopes. Many factors introduce complications into stability analysis. Most embankments contain heterogeneous soils, often of several types. This and other complications usually necessitate the use of a simplified cross section. At the same time, it is often necessary to adopt simplified average soil characteristics which represent actual characteristics as best as possible. Those steps which bear on the choice of the simplified section and the simplified soil characteristics are always important in stability analysis work. These steps are independent, however, …

Point Flow Measurements In Irrigation Furrows, David Ernest Mortin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new flow measurement concept is needed to facilitate the study of intake characteristics of the soil under furrow irrigation. Knowledge of the flow rate at various points throughout the furrow length is required but measurement must be made without altering the normal flow regime. Conventional water measuring devices such as weirs, orifices or flumes which require a loss of head in their operation, are usually unsatisfactory because to create a measuring head would alter the normal flow depth upstream thus changing the intake pattern.

The purpose of this study is to develop a simple, reliable method of measuring small …

Consumer Credit Knowledge And Credit Use In A Selected Group Of Married Student Households At Utah State University, Kay Daun P. Edwards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer credit has become an area of major importance in the financial planning of most, if not all, families in the United States. In absolute amounts, total consumer credit extended had increased more than 11 times, from $5,665 million to $63,164 million, since the end of World War II to 1962; and total installment credit had increased more than 19 times. During the same period disposable personal income had grown only about 2½ times (15).
