Phenotypic Expression And Genetic Analysis Of A New Drosophila Melanogaster Mutant (Eyes-Reduced) Exhibiting A Structural Eye Abnormality, James W. Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959), some flies from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Phenotypically the flies of this new stock resembled the established fourth chromosome eyeless mutants of D. melanogaster, and the new mutant was tentatively designated as eyeless-prime (ey'). Turner described the morphology of ey', and he also superficially investigated the genetic basis of the trait. The purpose of this investigation was to locate the genes associated with …

The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Some Factors Influencing The Response Of Halogeton Glomeratus To 2,4-Dichloropheloxyacetic Acid, Eugene H. Cronin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C. A. Mey. was introduced into the cold desert of North America sometime prior to 1934. The first collections were made near Wells, Nevada in 1935 (Zappetini, 1953) and the plant now occupies in excess of 10 million acres. The plant is poisonous to livestock. The toxic substances in halogeton are sodium and potassium oxalates which account for 17 to 30 percent of its dry weight, depending on the time of year it is collected (Dye, 1956, and Williams, 1960a). Since the plant is a pioneer invader on disturbed sites in the salt-desert shrub vegetation of …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a few instances an agricultural problem lend itself well to research into some of the more basic aspects of a problem as well as to research to determine the exact nature of the problem ad to prescribe a cure. Such a problem was found by the author to exist on a soil of the Twin Falls, Idaho area. Besides making an attempt to ascertain the exact nature of the problem, an experiment was set up in an attempt to understand more about the mechanism responsible for the problem.

The Effect Of Chelates On Phosphorus Availability And Mobility, Salah Ahmed Tahoun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil-phosphorus relations and plant-phosphorus relations have attracted the interest of many investigators since Liebig introduced his famous theory about the importance of the mineral matters to the plant in 1840. It was soon realized that phosphorus nutrition was a problem not easily solved for two reasons. 1. The added phosphorus fertilizers, soon after soil application are converted by some reactions in the soil to complex compounds far less soluble, consequently less available to the plant. Conclusions about this process led to controversial debates until it was discovered that a general statement covering all soils was impossible since the reactions involved …

Relations Between Transpiration, Leaf Temperatures, And Some Environmental Factors, Ronald Kay Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transpiration is the loss of water in vapor form from a plant. This is essentially the same process as evaporation except that it is modified by plant structure. Large quantities of water are removed from the soil, transferred through the conducting tissues of the plant, and dissipated into the air each day. As soon as the water is lost to the atmosphere, it becomes unavailable for human use.

The Use Of Objective Physical Measurements And Specific Selling Methods As A Basis Of Marketing Wool Through Pools, Don A. Huber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wool has been an important product in Utah since the pioneers arrived. The Mormon pioneers had with them 358 head of sheep upon entering the Salt Lake Valley. At that time there were also 12 head of sheep near Ogden, Utah belonging to Miles Goodyear, a trading post operator. These early people were very dependent upon wool for their clothing and numerous other products.

The Cost Of Owning And Operating Farm Power And Machinery Used In Tillage Operations On Diversified Farms In Selected Areas Of Utah, 1960, Clynn Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A current problem facing farmers is, how much should they mechanize their farm perations? As the relative price and productivity of factors change farmers usually have to adjust their operations to assure maximum profits. Technological advances often change the relative productiveness and the price of machinery. These changes have caused the progressive farmer to continually review his farm organization and make adjustments in levels of factor use. If he is to produce at maximum profits it is necessary that his machinery investment be in proper adjustment with other resources.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation was devoted to a study of food availability and the selective utilization by juvenile mallards (Anas platyrhynchos platyrhynchos L.) from hatching through the flight stage. Such information furnishes basic knowledge which may be used for determining the effects of chemical poisons on these organisms, how breeding ground habitats could be manipulated for their most efficient use by duckling species, what nutrients occur in natural duckling foods, and the digestibility of these items. The Bear River Migratory Bird Refuge, Utah, was used as the study area during the waterfowl breeding seasons of 1959, 1960, and 1961. Mallard ducklings …

Complexing Of Sugars And Polyhydroxy Alcohols With Molybdenum (Vi), Su Chin Kiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum is very important in the life processes of both plants and animals. It acts as a catalyst in promoting and controlling many biological reactions in living cells, but exactly what it does and how it functions are not well understood. In the past because of the obvious complexity of the reactions concerned and the extremely minute quantities of molybdenum involved, its presence was long undetected. Lately, molybdenum has drawn special attention on account of its effects on metabolic processes, particularly of plants. In this regard, molybdenum has been shown to be present in four enzymes: nitrate reductase (JJ), xanthine …

Within the boundaries of Utah are approximately 52.7 million acres of land. About 41 million acres are rangeland, of which 73 percent is federally owned and 5 percent state owned (6).¹ The portion owned by the Federal government is administered by the Bureau of Land Management (BLM) and the Forest Service. Most of this land is either arid or mountainous and has been used mainly for grazing in the past. IT has other uses, however, such as mining, forestry, recreation, and watersheds. Due to recent increases in population, personal income, shorter work weeks, and improved transportation facilities, these alternatives …

Student Teacher Attitudes Toward Child Aggression And Dependency In A Child Development Laboratory, Kristine Halls Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A child development laboratory in a university finds its first justification in its ability to contribute to the education of college students. After this justification has been established, the laboratory has a responsibility for serving the children enrolled in it.

The Child Development Laboratory at Utah State University serves college students in several ways. Students are able to observe and participate in the nursery school laboratory through experiences in various courses. The culmination of their course work comes when, as juniors or seniors, they do student teaching in the nursery school.

Some of the purposes the nursery school attempts to …

Differences In Frustration Reactions Of Nursery School Children, Sharon Marshall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of frustration has been of interest to various people including psychiatrists, psychologists, and educators for a number of years. These people have been interested in frustration because the complexity of our modern life has involved so many frustrating experiences. Frustration has been defined by Dollard (8, p. 7) as "an interference with the occurrence of an instigated goal response at its proper time." Ruch (21, p. 151) defined frustration as "the denial or thwarting by some obstacle which lies between a need and its goal." These two definitions are in essence identical. The average person has many obstacles …

The couples were selected from the geographic areas of Enterprise and Logan, Utah, and Preston, Idaho. Respondents consisted of couples who had at least one child, but no children beyond high school age. Their religiosity was determined by the bishop of the L.D.S. Ward of which they were a member. The bishop considered such factors as attendance at regularly scheduled church meetings and contributions made in the form of tithes in determining whether a couple was considered active or inactive. The sample consisted …

Selected Insecticides In The Control Of Invertebrates Possibly Associated With Avian Botulism, J. Larry Haddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Avian botulism or ''western duck sickness" has long been a major problem on duck marshes in the western part of the United States. This has been demonstrated to result from the ingestion of products of metabolism of bacterial cells of Clostridium botulinum type C. These products when ingested by waterfowl act as neurotoxins (Coburn, 1942). Studies have shown that many animal tissues are readily utilized as culture media by Cl. botulinum type C (Bell et al., 1955).

Since 1955 investigations have indicated a close relation between the occurrence of avian botulism and invertebrate population levels. It is thought that when …

An Evaluation Of Social Stars, Regulars, Neglectees, And Isolates In Ability-Grouped And Random-Grouped Classrooms, Benjamin W. Standing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education in the United States attempts to present maximum opportunities for learning in a democratic atmosphere. Many great educators have sought means to accomplish this end. Today, because of the stimulating force of other nations, even greater pressure is being brought to bear to achieve these goals. The plan of grouping pupils according to their abilities has been presented as one way to facilitate learning.

Ability grouping is the assigning of pupils who are essentially alike to special grade levels and to parallel sections of the same grade. Although it may be thought that ability grouping is a new procedure, …

An Analysis Of The Achievement Gains Made By Students In Ability-Grouped Vs. Random-Grouped Classroom Units, Luan H. Ferrin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because of the rapid advancements being made in the field of knowledge, educators, as well as those in other fields, must periodically take inventory. Current practices, policies, and methods must be carefully scrutinized to determine if they are the most effective. The group or class method of instruction is one such area.

Educational Grouping And Students' Self Concept, John N. Giboney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of ability grouping in education has achieved prominence, especially in recent years. Much of the emphasis placed on grouping students according to ability rather than chronological age is a product of modern times and progressive education. Although not accepted by all educators, there is a definite movement toward such a procedure in public schools today. It is held by the advocates of ability grouping that students will benefit more in a situation where they proceed at a rate prescribed by their ability rather than a hypothetical average or norm. Several well-controlled studies (3, 33, 44) have shown that …

A Comparison Of Underachievers And Normal Achievers At The Upper-Elementary And Seventh-Grade Level, M. Nephi Manning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That each is born with differing capacities and potentials is self-evident. Both students and teachers should accept as their right and duty the task of bringing to full fruition these latent potentialities.

It is a cause of concern in the nation, among parents and teachers, and in later years among students themselves, that many of our youth fail to achieve that of which they are capable. This is a loss to society and a disappointment to the individual.

The purpose of this study is to add to the growing fund of knowledge concerning factors related to this important area of …

A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nutritionists, the medical profession, and the public in general have become increasingly interested in low fat food products. Cheddar cheese, as it is now made, has a high caloric value and therefore may be discriminated against in some diets. The production of a reduced fat cheddar-like cheese would be of importance to the cheese industry by providing a reduced fat, high protein product.

The chemical nature of the casein furnishes the foundation for the body and texture in cheese. The body and texture of typical cheddar cheese is influenced principally by its fat and moisture content.

The use of hydrogen …

An Evaluation Of Antibiotics Upon Selected Dairy Organisms, Roy Brog

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to answer a three-fold purpose. Primarily, it has endeavored to measure the inhibitory effect of three antibiotics (potassium pencillin, dihydrostreptomycin, and oxytetracycline) on lactic acid producing organisms. The lactic acid-producing organisms include Streptococcus lactis, Streptococcus thermophilis, and Lactobacillus bulgaricus.

The determination of an effective dose of a given antibiotic which will inhibit 50 percent of the lactic acid-producing organism (E.D.₅₀) will be established. A 50 percent cut in acid development will certainly lead to an inferior product.

The secondary purpose has related to the detection of inhibitory substances (antibiotics) in milk. What is …

Rocks of Late Cretaceous age in the central part of Utah are dominantly elastic. In general, the sediments in the west are of conglomerate and sandstone of continental origin; the sediments in the east are of sandstone and shale of marine origin, These rocks were deposited at or near the western shore of a sea which extended from the Arctic to the Gulf of Mexico. The strand line lay in a general northern direction through Utah with land to the west and marine water to the east.

Molybdenum Chelates Of 8-Hydroxyquinoline-5-Sulfonic Acid, Ellis Ray Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Man has had an intense interest in the role of enzymes in biological reactions for many years. The basic question -- how enzymes are able to function so efficiently -- remains as yet largely unanswered.

Only in recent years has it been discovered that molybdenum is essential for certain biological processes. For example, traces of molybdenum added to certain soils have resulted in spectacular plant growth (1). Four enzymes are known to contain molybdenum: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4), and aldehyde oxidase (5). In each of these enzymes riboflavin is also present as the coenzyme FAD (flavin …
