Experimental Tissue And Peripheral Eosinophilia, Orson Lee Treloar Jr.

Biology

It has been known for some time that eosinophilia, either local or peripheral, is associated in some manner with the antigen-antibody reaction. Several theories have been proposed to explain this phenomenon. The most prominent of these theories at the present time is that proposed by Code (1944) and strongly supported by Archer (1963). These investigators contend that the release of histamine at the site of the antigen antibody reaction attracts eosinophils to the area. Litt (1964a), on the other hand, reject the eosinophilatactic function of histamine, but believes that the function of the eosinophil is to phagocytize the antigen antibody …

Utilization Of The Breeding Territory In The Black-Capped Chickadee, Raymond A. Stefanski

Biology

Breeding territorial behavior in birds is manifested in self-advertisement, localization of activity, increased conspicuousness, threatening postures, pursuit, or actual physical combat. The several activities represent a considerable expenditure of energy by the males. The function and significance of this behavior has been inferred from many studies in the past 35 years (Hinde, 1956), but until recently (Weeden, 1965; Stenger, 1958), no attempts have been made to quantitatively explain this phenomenon from empirical data.

The Diffracta Complex Of The Genus Polyphylla Harris (Coleoptera: Scarabaeidae, Melolonthinae), Ronald M. Young

Biology

The genus Polyphylla is distributed throughout the major portions of the northern and southern hemisphere but is more common in the temperate zones. Within North America the greatest number of species is in the western sections of the continent, being especially numerous in the southwestern and Pacific coastal regions of the United States. Blackwelder (1948) listed 26 species and one subspecies of Polyphylla which occur North of Mexico. Since then no additional species have been described.

Chlorophyll, Cartenoid And Protein Metabolism In Relation To Iron Chlorosis, Antaraguttu Subbayya Shetty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron as an essential element has been known since 1843, when Gris proved its need for the growth and well being of plants.

Operation And Management Guides For A Dairy Manufacturing Plant, Mohammad Valanejad

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

The dairy and food industries have become highly technical and almost completely mechanized. They also ranked as one of the greatest industries in the country at the present time and represent an investment of many billions of dollars.

The rigid health department regulations, together with the special processes required, call for many types of specialized equipments and procedures. Most of the processes require heat, power, and refrigeration. More exact control of processes, as well as more efficient operation, have become increasingly important as these industries have matured and as competition has become keener. Material handling and automation are major developments …

Sex Preferences And Identifications Of Young Children, Loa Thomson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The acquisition of normal sex-role behavior is one of the fundamental tasks which goes into developing a healthy personality. More needs to be understood about the processes involved in adopting proper sex-role behavior patterns. How does a little girl adopt the feminine role and learn to be a woman? How does a little boy adopt the masculine role and learn to be a man? From the studies in clinical psychology and psychiatry, it is evident that personality maladjustments and certain forms of emotional disorders appear to be related to difficulties in sex-role adjustment. This suggests a close correlation between childhood …

Effect Of Calcium Availability On Alfalfa Grown In Calcareous High Sodium Soils, Harry Irving Nightingale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil science we shall always be confronted with reactions in soils that involve Ca. Early recognition of this led to experimentation in this area. Due to the fact that Ca deficiency is most common in acid soils, the majority of the experimentation has in the past been largely confined to acid soils and their soil-Ca-plant relationships. There has been relatively little research done with Ca and its availability problems associated with alkaline or sodic soils.

A Revision Of The Bee Genus Epeolus Latreille Of Western America North Of Mexico, Richard L. Brumley

Some Movements Of Black-Tailed Jackrabbits In Northern Utah, Donald H. Rusch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This work describes the extent and pattern of some black-tailed jackrabbit (Lepus californicus) movements and areas of activity in northern Utah and their relationship to sex and age, and season of the year.

Black-tailed jackrabbits are the most common lagomorphs in much of the western United States, particularly in that vegetational association described by McDougal (1908) as the sagebrush desert. Furthermore, Adams and Adams (1959) have suggested a correlation between sagebrush (Artemisia tridentata) incidence and jackrabbit density.

Farmers often regard this species as a liability because of its depredations on alfalfa (Medicago sativa), crested …

The Effect Of Fluoride On C14O2-Fixation And The Synthesis Of Organic Acids, Amino Acids, Protein And Carbohydrates, Chin-Fung Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many studies have been conducted on the effect of fluoride on plants, but the exact mechanisms by which fluoride causes damage is little understood. The following physiological and metabolic processes are known to be affected by fluoride: a decrease in chlorophyll (McNulty and Newman, 1961), a diminished rate of photosynthesis (Thomas and Hendricks, 1956; Bishop, et al., 1958), decreased plant growth (Bonner and Thimann, 1950), inhibition of ascorbic acid synthesis (Smith, 1952), variation in starch and total polysaccharides (Donald and Emerson, 1961), inhibition of glucose transport (Jiri, et al., 1962), inhibition of metabolism (Ordin and Skoe, 1963), effects …

The Relationship Between Personality As Measured By The Minnesota Multiphasic Personality Inventory And Interest As Measured By The Kuder Preference Record, Robert Glen Knudsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Counselors frequently use batteries of psychological tests in helping students to select appropriate educational and occupational choices. The task of interpreting scores on a battery of tests to students is not at any time a simple undertaking. The trend toward emphasis on the importance of the relationship among the various scores in a battery of tests, has further complicated test interpretation.

Vocational choice theories suggest an interrelationship between vocational interests and personality characteristics. They further suggest that different educational majors and occupations require different types of vocational interest and personality characteristics. Two tests, The Minnesota Multiphasic Personality Inventory (hereafter referred …

A Tropical Colonization Experiment In Mexico, Charles Ray Alban

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One day in March 1963 in the city of Torreon, State of Coahuila, Mexico, a group of 492 heads of families said goodbye to their wives, children, relatives, and friends, and boarded a train to begin a long journey south and east to a new and, they desperately hoped, better life, with land of their own to work and to love. It would be almost a full year before the families would be reunited in a new and different environment.

The Kinetics And Mechanism Of The Reaction Of Molybdenum(V) With Iodine, Oxygen And Nitrate, Ervin Park Guymon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum compounds present a series of baffling chemical puzzles. By no means are all of these yet even clearly defined and many may never be. This complexity results from the ability of molybdenum to form six different oxidation states, which can possess three different coordination numbers. Furthermore, molybdenum compounds readily disproportionate to yield mixed valence compounds; and finally, molybdate ions readily aggregate in solution to form a variety of polyions by polymerization-condensation reactions which are controlled by pH and the concentration of the system. Molybdenum's complexity can best be summed up in the words of the late Edgar Smith who …

The Effects Of Teaching Experience On The Counselor's Perception Of His Role And Effectiveness In Counseling, Benne D. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prior to World War II, the question as to whether or not public school counselors needed public school teaching experience would never have entered the minds of counselor educators, employers, or any other persons concerned with this matter. In the teaching field, a premium was placed on experience and often times an apprenticeship for a position had to be served. With today's shortage of teachers and counselors, a number of persons have been employed as public school counselors without teaching experience. The effects of the employment of public school counselors without school teaching experience has caused many questions to be …

A Study Of 5-Fluorouracil: Its Effects And Mode Of Action In Drosophila Melanogaster, John B. Jenkins Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations involving the fluorinated pyrimidine, 5-fluorouracil, and its effects on viruses, bacteria, plants and mammals, have brought to light the following facts: FU inhibits the growth of bacteria, plants and mammalian cells and it decreases the ability of certain viruses to produce progeny. In other words, FU is an antimetabolite that inhibits growth and/or reproduction. Two mechanisms have emerged from these studies to define the mode of action of FU. The first mechanism involves the incorporation of the compound into the RNA of the organism thus altering the base sequence and creating a non functional or damaging nucleic acid. The …

Radiosensitivity And Cytogenetic Studies On An Interspecific Grass Hybrid, Paul James Bottino

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The complex response of plants to ionizing radiation has never been clearly understood. One of the main problems is the differential sensitivity of plants to radiation. A clear understanding of differential sensitivity lies far in the future. For the present a major question is: can we predict the radiosensitivity of a plant before radiation exposure? Some progress has been made in answering this question. Sparrow et al. (29) feel that they have a useful statistic which can be used to predict the approximate radiosensitivity of a plant. Average interphase chromosome volume has been tested on sixteen species of herbaceous plants …

Host-Parasite Relationships Between Prunus Mahaleb And The Parasitic Nematodes Pratylenchus Neglectus And Meloidogyne Hapla, Bernard Al Tait

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah orchardists have encountered problems which they have needed to control for continued successful and economical fruit production. Some of these problems are diseases such as western-X virus, cytospora canker (Wadley, 1955) and codling moth (Davis, 1957). These diseases, because of their nature and severity, have received more attention than others.

Effect Of Fluoride On Respiratory Enzymes In Soybean Leaves, Arthur Chiu-Eng Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many reports relating the effects of fluorides on plant respiration. Fluoride has been regarded as an inhibitor of respiration. Warburg et al. (1942) demonstrated that fluoride inhibited enolase activity, therefore, decreased the respiration rate of yeast. Miller (1958), found a similar inhibition of enolase from pea seed. Bonner (1948), Bonner and Wildman (1946), and Laties (1949) reported that the fluoride ion in culture solutions reduced the respiration rate in Avena Coleoptile, spinach leaves and barley roots. Since the inhibition was reversed by the addition of pyruvate, they concluded that the inhibition of respiration was due to the inactivation …

Reactions To Parenthood, Geraldine Rosine Brinley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parenthood is a common experience, in the sense that it is almost universal among married couples, but it is a unique experience in the sense that there are great individual variations in its meaning and its impact upon the life of each parent.

In spite of the many variations in reactions and responses to parenthood, a stereotype reaction seems to prevail. The stereotyped conception of behavior following the conception of a child is for the wife to be filled with some inner joy which causes her to behave mysteriously for a time until she reveals the unsuspected truth to her …

Sound Communication In The Uinta Ground Squirrel, Donna Mae Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Numerous investigators have studied sound communication in animals in recent years. Most of these studies have been on birds, insects, or cetaceans, particularly the dolphin. Most of the studies on terrestrial mammals have been of the natural history type, and the authors have given an orthographic rendition of any sounds produced by that particular species. Few definitive studies have been done. There have been a few attempts to determine cause and function of sounds in mammals (Arvola, lImen, and Koponen, 1962; Bartholomew and Collias, 1962; Rowell and Hinde, 1962; Andrew, 1963).

No quantitative studies on sound communication in Citellus have …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water has become one of major national concerns, and it is the limiting factor in the expansion of an irrigated agriculture. Irrigation development is rapidly growing all over the world. New lands are being brought under irrigation and older irrigation lands are being improved. In the planning and operation of an irrigation project, the estimation of water requirements and evapotranspiration, or consumptive use, requires careful consideration. A knowledge of evapotranspiration is playing an increasingly important part in irrigation science. It is the best index of water requirements which represent the amount of water that should be applied by irrigation for …

A Longitudinal Study: The Relationship Of Various Physical Characteristics To Serum Cholesterol In Preadolescents And Adolescents, Carol Ann Milligan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although many theories have been formulated concerning atherosclerosis and its relationship to the incidence of coronary heart disease, few actual facts are known. It is known that atherosclerosis is very complex and appears to be influenced by many factors. It is postulated that an elevated serum cholesterol level is one predisposing factor.

Serum cholesterol levels are likewise influenced by many factors. Age, sex, body build, exercise, socio-economic levels, smoking, health status, weight loss or gain, dietary fat, endocrine function, and stress have been shown to be related to serum cholesterol levels, and according to some authors also are related to …

The ruffed grouse (Bonasa umbellus incana) inhabits much of the deciduous woodland of northern and central Utah. Its distribution is confined mainly to the Wasatch and Uinta mountain ranges. It has been observed in willows (Salix spp.) at 5, 000 feet elevation and in Douglas-fir (Pseudotsuga menziesii) at 9,000 feet.

An Evaluation Of The Differences Among Lower, Middle And Upper Socio-Economic Groups In The Sixth Grades In The Ogden City Schools With Regard To Scholastic Achievement, Milton Kendrick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are some inadequacies in our American way of life. One of these is the inadequate help and attention given to the problem of children who become shackled with their lower class environment with little or no desire or incentive to rise above this. The major challenge to any teacher is the ability to stimulate and inspire children to achieve or succeed. There are different degrees of achievement. For one child, great achievement is not the same as for another. The realization of this prompted the decision to see what differences in achievement exist among the three main socio-economic classes. …

A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.

While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …

A Campus Planning Concept And Its Applicability To Utah State University, J. Mcray Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary assumption used in justifying this thesis is that growth and expansion will continue to occur for Utah State University. This is almost a certainty in view of the national trend and a general increase in the enrollment at Utah State University of from 6% to 7% over the past 10 years.

Error Structure Of Randomized Design Under Background Correlation With A Missing Value, Tseng-Chi Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The analysis of variance technique is probably the most popular statistical technique used for testing hypotheses and estimating parameters. Eisenhart (12) presents two classes of problems solvable by the analysis of variance and the assumption underlying each class. Cochran (9) lists the assumptions and also discusses the consequences when these assumptions are not met. It is evident that if all the assumptions are not satisfied, the confidence placed in any result obtained in this manner is adversly affected to varying degrees according to the extent of the violation.
