The Comparison Of Bacteriophage Sensitivity Of Staphylococcal Isolates From Turkeys, Turkey Processors, And Dairy Workers, Daryl Eugene Peterson

Biology

There have been several surveys made throughout the State of Utah that indicate the presence of staphylococcal synovitis in many of the turkey flocks. Bagley (1949) and Blommer (1950) indicated that from 1947 to 1949, there was a widespread occurrence of the disease throughout the State. Dr. M. L. Miner (1960), Head of the Department of Veterinary Science (Utah State University), indicated that staphylococcal synovitis in turkeys has actually been continuous in Utah since the late nineteen-"thirties." Staphylococcus aureus was found by Prahl (1891) to be the etiologic agent of this synovitis in geese. Synovitis may occur in many other …

The Morphology And Cultural Characteristics Of Bovine Cecal Trichomonads, Emron A. Jensen

Biology

No extensive investigation has been made of the trichomonads living in the cecum of cattle. Two species of trichomonads found in the intestinal tract of cattle have been described. Trichomonas bovis was described by Pavlov and Dimitrov (22). Trichomonas enteris was described by Christl (5). The descriptions given were not complete in that no mention of parabasal bodies was made and specimens stained by methods other than iron-hematoxylin were not described.

The Behavior Of Certain Genes Associated With Tumorous Head In Laboratory Populations Of Drosophila Melanogaster, William D. Berseth

Biology

The tumorous head trait first appeared in a stock of flies maintained at the University of Texas which had previously been collected at Ocahuizolta, Mexico. The tumorous head trait is evidently deleterious to the individual expressing it so it was not evident if the trait would continue to be expressed if it was not selected for. Later investigations indicated that alleles of the tumorous head trait were uniformly absent in some and present in other "wild" laboratory stocks. Different alleles had varying effects on the percentage of expression of the trait. It was not known why alleles of the trait …

Population Structure Of Peromyscus Maniculatus In Two Areas In Green Canyon, Cache County, Utah, John O. Sullivan

Biology

Mammalogists in recent years have demonstrated an increased interest in the population dynamics of small mammals. Many small mammals are nocturnal and consequently are difficult to observe directly. A technique of live-trapping and marking is the most feasible method of studying such animals (Blair 1942; Calhoun and Casby, 1958). This permits the consideration of individual animals. The recognition of individuals contributed to the development of other techniques used in the interpretation of small mammal populations. The "home range" concept discussed by Burt (1943) and Stickel (1954) and the "center of activity" method as described by Hayne (1949) also contribute to …

Graduate Recital, Alma C. Cook

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

The writer, after conferring with his graduate committee, selected a lecture-recital project in partial fulfillment of the requirements for his Master of Science degree in Music Education. As a junior high school instrumental teacher and specialist on the low brass instruments, he was advised by his committee chairman, Professor Max F. Dalby, to also utilize some of his junior high school students on the recital. It was suggested that he play various instruments with them, as well as appropriate solos on his major instruments: euphonium, tenor trombone, and tuba. To show the writer's versatility, it was also suggested that a …

Prediction Of Academic Success In The College Of Forestry, Ronald Skeen Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The College of Forest, Range and Wildlife Management (hereafter referred to as the College of Forestry) at Utah State University has been concerned for some time with the problem of selecting from the applicants to their school the ones whom they think will be able to complete the requirements for graduation. The large number of freshman students placed on probation at the end of the fall quarter and of succeeding quarters each year fives some idea of the magnitude of the problem. It is not unusual for 40 or 50 percent of the entering freshmen to be in this category.

Sedimentation And Diffusion Coefficients Of Legoglobin Fractions, Alfonso R. Trujillo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The preparation of root nodule extract by Virtanen, et. al., has created a good deal of interest in the study of plant hemoglobin (legoglobin). In the preparation of any new substances, it is of interest to determine the physical constants of the new species.

The Influence Of Water-Reducing Admixtures On The Curing Of Concrete, Wallace Don Budge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water-reducing admixtures in concrete has grown continuously since their introduction over 25 years ago, with a present estimated usage in the production of 25 million cubic yards of concrete annually in the United States alone. Opposition to anything added to concrete, other than cement, aggregates, and water, is gradually disappearing, and considerable recognition is being given to the value of using other ingredients.

The research contained in this study may be divided into two portions: tests to determine the rate of volume change of cement paste and compressive strength tests to indicate the effect of moist curing …

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 …

An Analysis Of The Differential Responses Of A Group Of Nursery School Children To A Variety Of Musical Presentations, Eva Louise Godfrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problem of what kinds of music provide the most meaning for the young child has long been a concern of the author. It arises not only out of close experience with young children, but also out of a concern for the responsibility of providing them with meaningful aesthetic experiences. From this background of experience the problem is not purely an academic one. Its first and ultimate concern is an experiential one. Because it arises out of this particular background, the analysis of the problem and its study is less concerned with academic and scientific validity than might otherwise have …

Alfalfa Resistance To The Clover Seed Chalcid Bruchophagus Gibbus (Boheman), Gerald Douglas Minion

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The destructive nature of the clover seed chalcid has been known since the latter part of the 19th century. This jet-black Hymenoptera, often called the "chalcis-fly," destroys from 10 to 20 percent of the alfalfa seed in Utah each year. Damage as high as 85 percent has been reported.

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.

Research On Repertoire Used In Vocal Recital, Drew Van Wagoner

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

The selections in the recital given by the candidate can be divided into four sections. The first four songs can claim as their origin in time the early Italian school of the Baroque period. The two selections following these represent the oratorio. The aria by Haydn properly comes from the Class-ical era. The aria from Mendelssohn's oratorio is from the Romantic period, but it is referred to as Classicist-Romanticist, due to different elements of style and technique used by the composer.1 The third part of the recital is composed of art songs, taken from the German Lieder group, the first …

Graduate Wind Instrument Recital, Harold W. Boyce

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

Since the end of World War II most teacher-training institutions have reinforced and expanded requirements for graduation in instrumental music education; but the problem still remains of determining the actual training needs of the instrumental music educator and the manner in which these needs can best be fulfilled in the relatively brief period of time available for educating the teacher . It is the responsibility of the music departments of the teacher-training institutions to determine the most practical and efficient courses and projects which will better equip students in instrumental music education for teaching general music classes, performing on their …

Graduate Percussion Recital And A History And Development Of Percussion Instruments And Percussion Music, Ned S. Mortensen

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

In today1s public school band the percussion section is often neglected. Some band directors consider the percussion section a place to deposit outcasts. Even though a full, accurate and well-trained percussion section adds polish to a band, few band directors admit its importance. Percussion instruments are seldom recognized as effective solo and ensemble instruments even though both solo and ensemble work can help the percussionist become an accomplished musician.

In this paper, it is proposed to examine the history and development of percussion instruments and percussion music and to thus establish the importance or the percussion section in the public …

Improving Elementary School Singing, P. Annette Hansen

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

The problem of helping children to make continual progress in their singing ability has been of particular interest to me because of the experiences I have had in teaching music to third, fifth, and sixth graders. In most cases the children had had few teachers who were trained or experienced in teaching music. In one district there wasn't even a music supervisor to whom teachers could go for help if they felt they needed it.

The problems on which I have done research to write this paper are the ones which have been the most common in my experience. I …

Differential Responses Of Student Teachers To Children In Nursery School, Carroll Carman Lambert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For some time the writer has observed the keen, creative sensitivity with which children respond to their world. She has also observed, however, that many teachers and parents seem to be quite unaware of this sensitivity. An illustration of this lack of awareness is the following experience: One day a nursery school teacher had a painful headache; in fact, it was suggested that she go home for the remainder of the day. Instead of going home, however, she decided to stay, thinking that her headache would soon abate. The teacher was sitting on a chair observing the children, unaware that …

A Study Of The Homeroom Program In Three Senior High Schools In Utah, Ida D. Draayer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The function of the secondary school is to help each individual develop and direct all of his potentialities. It should seek to help boys and girls find their rightful places as citizens in a democratic world. The fact that each individual is different presents a distinct challenge, and the secondary school is capable of meeting this challenge of individual development if the homeroom functions as it should.

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 Influence Of Nitrogen And Phosphorus Supplements On The Composition Of The Ruminal Ingesta Of Sheep Grazing Desert Range Forage, James G. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approximately 46 million acres or 88 per cent of the land area of the state of Utah has been classified by Reuss and Blanch (1951) as "range land open for grazing." Although some of this area cannot be grazed because of inaccessibility, lack of water, poison plants, and similar factors, it is estimated that some 40 million acres or 78 per cent of the total land area is available for grazing. Most of this grazing land is federally owned (73 per cent), while only 22 per cent is privately held, and 5 per cent is state owned.

Land Tenure Problems In Iran, Jalil Mahmoudi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Land tenure problems throughout the Middle East and most of the underdeveloped countries of the world are considered by competent international organizations and many students of world problems as one of the greatest contributing forces to social unrest and a barrier to economic development.

When the United Nations' General Assembly at its fifth session in 1950, had under discussion the problem of land reform in many underdeveloped countries, the consensus of opinions were that the conditions affecting land reform reduced agricultural productivity and were a major cause of low standards of living for the populations of those countries. The General …

The Effect Of Moisture And Temperature On Transformation Of Applied Ammonium Sulfate In Several Western Soils, Lloyd Richard Hossner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The conversion of ammonia nitrogen to nitrite and nitrate forms of nitrogen has aroused much attention in the past and continues to receive much of the energy of the present day researcher.

Economics Of Wool Marketing In Utah, E. Jay Berry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of history the wool of sheep has been used by the human race. Its chief use has been and still is for clothing. Also, it is widely used for blankets, upholstery, carpets, and numerous other products.

The wool industry is important to the state of Utah, which was the sixth largest producing state in the United States in 1958. Wool growers in Utah received approximately $7,897,000 in sales proceeds and government payments for wool sold during the 1958 marketing year (12).¹

Phosphorus Status Of Genola Soils In Utah, Warren E. Bendixen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With increasing pressure on economical production of crops, more fertilizers are being applied to the soil each year to increase crop yields. Economical production of crops with applications of fertilizer requires an evaluation of the essential elements of the various crops so applications of fertilizer will not exceed the law of diminishing returns.

Because varying soil, moisture, and climatic conditions influence the response to added fertilizers, some workers (18, 26, 38) have contended that the only reliable way of determining the fertilization needs of a crop is to conduct a trial on the particular farm. The length of time involved …

The Mineral Content Of Various Sections Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Hyrum Del Var Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The so-called "lime-induced" chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. The characteristics associated with lime-induced chlorosis are the same as those associated with iron deficiency chlorosis--interveinal yellowing of the leaves at the meristemic region combined with reduced vigor of the plant as a whole. Lime-induced chlorosis is unique in that the iron content of both chlorotic plant and the soil do not always show a deficiency in iron when chemically analyzed. This leads to the theory that iron is inactivated in both the soil and plant.

Although no single factor …

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.

The Use Of Tetrazolium As A Measure Of The Salt Tolerance Of Alfalfa, Daryl A. Freter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The task of obtaining and selecting plants which may not only survive under salty conditions, but grow and produce satisfactory yields is varied and complex. It is becoming necessary to select and breed crops for salt tolerance. Plants can be grown in artificially constructed salt basins to test their individual salt tolerance, but this takes time, at least one year. It would be desirable to develop a rapid test to determine the salt tolerance of a given plant. The use of a dye in conjunction with a series of salt solutions has been suggested for determining the salt tolerance of …

The Influence Of Temperature On The Impedance To Water Flow Through Plants, Royal Duane Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This era has been termed the atomic or space age. The greatest concern of most people seems to be centered around survival from the destruction and suffering that might be caused by atomic and nuclear weapons. However, along with this, the world is confronted with perhaps a greater disaster--a potential calamity seldom realized by most people, yet a problem which grows more serious in the world each year--a tragedy which would probably be worse than destruction from nuclear weapons. This encroaching catastrophe is starvation.

Even today the majority of the people in the world do not have enough food. Each …

A Determination Of The Earth's Gravity Field In Spheroidal Coordinates, M. Spencer Hamilton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The earth's gravity field G * at a point P in the region surrounding the earth's surface is defined as the force acting on a unit mass concentrated at P. This is a force resulting from two components: (1) G₁ due to the gravitational attraction of the earth's mass, and (2) G₂ due to the earth's rotation.

As a result of Newton's law of gravitation, G₁ can be written in integral form as follows:

G₁ = k ( (_V ( rdm/r³

where r = PQ, r = |r|, Q is a point which ranges …
