All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lime-induced chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. There are many factors associated with and influencing this form of iron chlorosis and because of this it has been very difficult to determine the relationship between the factors and chlorosis.

An Analysis Of Class Size, Teaching Load, And Instructional Salary Costs In Utah State-Supported Collegiate Institutions Of Higher Education, Don K. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that the State of Utah attempts to provide schooling to a higher proportion of youth than other states in the nation. Utah has the largest proportion of high school graduates (50 per cent) in its adult population, and also the highest median school years completed (12.2 years) by adults 25 years old and older. These are some of the highlights of the 1961 edition of the "Rankings of the States," an annual publication in which the National Education Association compares all 50 states in terms of educational effort and achievement.

Pressure Dependence Of Soil Water Matric Potential, Bozorg Bahrani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The partial specific Gibbs¹ free energy or the chemical potential has been shown to be the most desirable thermodynamic function for describing soil-water systems. The absolute value of the chemical potential of soil water cannot be determined. If pure water at standard temperature and pressure is taken as the reference, the difference between the chemical potential of soil water and that of the reference can be measured and is called "soil water potential," which has the dimension of energy per unit mass.

The barometric pressure at the sea level has been accepted as the standard reference pressure. Thus, any …

The Lower Devonian Water Canyon Formation Of Northeastern Utah, Michael E. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1948 Williams subdivided the Jefferson Formation of northeastern Utah into two formations. The upper formation was referred to as the Late Devonian Jefferson Formation and the lower formation the Early Devonian Water Canyon Formation (Williams, 1948, p. 1138). Since that time detailed study of the Water Canyon Formation has not been made. It is the purpose of this investigation to describe in detail the lithology and paleontology of the formation and their implication as to the environment of deposition of Early Devonian time in northeastern Utah.

Factors Affecting The Price Of Turkeys And Their Usefulness In Decision Making By Utah Turkey Producers, Anthon H. Turley Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of turkeys in Utah has had a rapid growth since its beginning a few decades ago. In 1929 there were only 226,000 birds sold by Utah producers and in 1960 there were 2,798,000 birds sold. Over this 31 year period of time production has increased 12 times.

Gross income received in 1960 for Utah turkeys amounted to $13,787,000 and accounted for 8.35 percent of total farm income in Utah in 1960 (2).

In addition to the income direct to turkey producers, this industry contributes to the incomes of various other industries such as processors, feed handlers, hatcheries, transportation agencies, …

Nitrogen Effect On Cation Exchange Capacity Of Plant Roots, Kamilia Shoukry Mohamed Shoukry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationships that exist between soil and plant are very complicated and have aroused man's curiosity for centuries. Many studies have been done in order to understand and clarify this relation. Among these is the hypothesis that plant roots exhibit cation exchange capacity (CEC) and that this is in some way responsible for differential cation uptake . The CEC of the roots was defined by Helmy (l958a) as the total cations which can be exchanged or replaced from the root surface under a given set of conditions and is usually expressed as milli-equivalents per 100 grams (me/100 g) of dry …

Topological Groups, Nicolas Anthony Thireos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A topological group is an abstract group which is also a topological space and in which the group operation are continuous. In group theory the algebraic binary operation of passage to a limit is studied in a similar manner. The two fundamental mathematical concepts of binary operation and passage to a limit are united and interrelated in the concept of topological group.

The concept of topological groups arose from the study of continuous transformations. However, topological groups can be studied quite independently from continuous transformations and the latter can be presented as applications of topological groups. The first person to …

Leaf Ribonuclease Activity As Related To Virus Infection, And Ribonucleic Acid Concentration, Andrew Chien-Yau Hsu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ribonucleic acid (RNA) appears to be the entity responsible for infectivity and genetic continuity in certain plant, animal and bacterial viruses. RNA also plays an important role in protein synthesis. The enzymes which are involved in RNA synthesis and degradation have received much attention. Among these enzymes ribonuclease (RNase) has been most thoroughly studied Rnase is widely distributed and has been isolated from many sources such as snake venom, bacteria, the pancreas, and many plant and animal tissues. Most studies with RNase have been concerned with its role in the hydrolysis of RNA in vitro. Therefore, it has generally been …

Mineral Salt Movement In Roots As Affected By Various Factors, C. James Lovelace

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants necessitates that they have certain elements to fulfill their mineral requirements. Environmental conditions play an important part in fulfilling these needs. Should any of these essential elements be lacking, the plant displays certain symptoms. Although iron has been classified both as a micro-element and a macro-element, it is undoubtedly necessary for all plants to some extent.

Studies And Observations On Potato Powdery Mildew, Brent C. Palmer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the past several years, powdery mildew disease has become an increasingly important problem to potato growers in the northern part of Utah. In some fields, reduction in yield due to powdery mildew has been estimated to be as high as 30 percent (Treshow and Cannon, 1961). The disease has been reported from many parts of the world. Other than in Utah, however, the only place where it has been considered to be of economic importance is Palestine. In that country, reduction in yield has been estimated to be as high as 20 percent (Palti and Moeller, 1946).

The Respiratory Chain Involved In Oxidative Phosphorylation On Higher Plants In Relation To Carbon Dioxide-Bicarbonate Inhibition, Wan-Jean Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased concentrations of CO₂ with the accompanying high bicarbonate level in the culture medium have been reported to have a depressing effect in certain plant species on growth (34), respiration (23, 33), oxidative phosphorylation (9), mineral nutrient absorption (17), certain enzymatic reactions (4, 22, 27), accumulation of organic and amino acids (11), and protein synthesis (16). Since accumulation of organic acids occurs in lime-induced chlorotic tissue together with a depression in the respiration of plant tissue, an effect on the energy transfer mechanism of such plants is suspected. Inhibition of electron transfer from the substrate level could result in …

Infrared Spectroscopy As Applied To The Study Of Biochemical Changes Induced By Tobacco Mosaic Virus In Leaf Cells, Banavara Krishnappa Chandrasekhar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The biochemical reactions occurring during the early stages in the infection cycle of a plant virus are still unknown. Many studies involving bacteriophage and animal viruses that have been made in recent years have provided evidence of the nature of virus infection, but these have not been of much value in understanding the nature of plant viruses. Infrared spectroscopy applied to the study of viral infection processes by Chochran and his co-workers (1960, 1962) have given some clues about the nature of biochemical changes taking place in the leaf tissues as a result of infection with cucumber mosaic virus and …

A Field Study Of Miscible Displacement In Saturated Soils, Lloyd Dowley Mcfadden Sadler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extensive research has been carried out in both field and laboratory to explain water and solute movement under both saturated and unsaturated conditions. The importance of such work is obvious, since any attempt at exploring land reclamation by leaching or nutrient movement in plant feeding (to name only two) is subject to interpretations and theories of moisture flow.

Water flow through soil during reclamation by leaching can be termed miscible displacement since soil water and leaching water do not have a distinct fluid-fluid interface and will physically mix. It is probable that miscible displacement investigations can contribute to an understanding …

A Further Study Of Perceptual Defense, Alma L. Carlisle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years, psychologists have been trying to find the relationship between perception and different factors of personality. Different experimental techniques were constructed to measure these concepts. One of the tools used to measure personality factors and their effect on perception was the tachistoscope. Through the use of this instrument, words or pictures could be flashed on a screen at varying rates of speed, or illumination. The subject upon watching these flashes, would relate the information which he perceived.

An Investigation Of The Properties Of Join Geometry, Louis John Giegerich Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a proof that the classical geometry as stated by Karol Borsuk [1] follows from the join geometry of Walter Prenowitz [2].

The approach taken is to assume the axioms of Prenowitz. Using these as the foundation, the theory of join geometry is then developed to include such ideas as 'convex set', 'linear set', the important concept of 'dimension', and finally the relation of 'betweenness'. The development is in the form of definitions with the important extensions given in the form of theorems.

With a firm foundation of theorems in the join geometry, the axioms of classical geometry …

The Effects Of Cooking Temperature And Stage Of Doneness On Some Factors In Broiled Beef, Carmencita Salvosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Broiling is cooking tender cuts of meat by radiant heat from hot coals, a gas flame, or an electric element. Steaks and chops for broiling are from 1 to 2 inches thick.

Broiling as a method of cooking mat is not new, but the directions for the process are the result of individual trial and error testing and are often in conflict. Current interest in indoor and outdoor broiling, particularly in Western United States, emphasizes the need for better information. There is no measuring device for surface heat during broiling and thus little research on the relationship of surface temperature, …

Effects Of Beaver On Stream Flow And Water Quality, James W. Bates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water, one of the major resources of the western lands, controls the economy and expansion of the communities. Industry, agriculture, timber, livestock, game and home water needs are all dependent upon a steady and continued flow of water from wells, springs, and rivers. Water is derived from one source, precipitation, which occurs in the form of rain and snow. Watersheds which are properly managed accumulate a substantial snow pack during the winter which is the life-giving source of water for our springs.

The Utah Water and Power Report (1948) indicates the annual precipitation over the entire state of Utah averaged …

Studies On Eating Quality Of Meat: I. Palatability And Tenderness Of Lamb: Ii. Tenderness Of Turkey, Georgia C. Lauritzen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein was the first substance recognized as a vital part of living tissue. About 18 percent of the human body is in the form of protein, and certain protein constituents can be obtained only from dietary sources. Since meat is the chief source of protein in the normal diet, this study was aimed primarily at factors influencing quality of meat. The problem included two particular meats, lamb and turkey.

The per capita consumption of lamb in the United States is lower than that for any other meat. In 1944 in the United States 6.7 pounds of lamb were eaten per …

Thermal Degradation Of Pigments And Relative Biochemical Changes In Cherries And Apricots, K. B. Dalal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The extent and nature of biochemical changes that take place in canned fruits during storage temperatures above freezing have been reviewed and discussed by Pederson, et al. (1947). These changes include loss in nutritive value, e.g. ascorbic acid, thiamine (Brenner, et al., 1948) and deterioration of color (Tressler, et al., 1955). Bauernfeind (1953) reported that canned peaches, apricots, and sweet cherries, after a few months of storage at 70°F, frequently undergo changes such as destruction of anthocyanin and carotenoid pigments with the subsequent formation of brown colored compounds. Darkening of fruit-color eventually results in their unacceptability at …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Comprehensive population studies in the field of fisheries are in great demand. Many of our fishable waters are being changed, and we need to be able to predict the results of these habitat alterations. We must know how to include beneficial modifications in readjustments of habitat in order to create a fishery or prevent destruction of an existing one.

The acceptable situations for good fish production in large mountain streams are not well-known. A fishery can be properly managed only if the manager has sufficient knowledge of the carrying capacity of the habitat, the survival and mortality of the population, …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past century, vast and rapid changes have transpired in our national life. They have been occasioned by extensive technological, social, and industrial changes and by the emergence of cheap, fast transportation, new techniques for preservation of food, and other basic inventions. Many changes, too, have been brought about in American courtship, marriage, and family living patterns. Some of the most far-reaching changes have been those in the social and psychological roles of the individual in relation to the family.

Effect Of Forage Height Upon The Microtemperature Of A Grass-Legume Pasture And A Comparison Of Forage Composition, Robert E. Warnick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of pasture to provide low cost feed for dairy and other farm animals is an important factor in the success of livestock operations.

Some of the factors which influence the income from pasture land are: management, pasture mix, and climate. The management of a pasture can determine to a great extent the value of pasture in a farming enterprise. Irrigating the pasture at the right time, using the right fertilizer, and proper methods of harvesting are examples of some of the management problems facing the grassland farmer.

Salt Effect On Water Requirements Of Plants, Abdel-Wahhab M. H. Sallam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water requirement was defined by Briggs and Shantz in 1911 as the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter formed during the whole or any part of the life cycle of the plant. Miller (1938) and Kramer (1959) postulated that …
