All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two computer programs were developed using a CDC 3100. They were written in FORTRAN IV.

One program uses four tape drives, one card reader, and one printer. It will calculate factorial analysis of variance with or without covariance and/or multivariate analysis for one to eight factors and up to twenty-five variables.

The other program is used for completely randomized designs, randomized block designs, and latin square designs. It will handle twenty-five treatments, rows (blocks), and columns. The program can handle fifteen variables using any number of these variables for covariates.

An Exposition On Bayesian Inference, John Laffoon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Bayesian approach to probability and statistics is described, a brief history of Bayesianism is related, differences between Bayesian and Frequentist schools of statistics are defined, protential applications are investigated, and a literature survey is presented in the form of a machine-sort card file.

Bayesian thought is increasing in favor among statisticians because of its ability to attack problems that are unassailable from the Frequentist approach. It should become more popular among practitioners because of the flexibility it allows experimenters and the ease with which prior knowledge can be combined with experimental data.

Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.

With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

A Study Of Amino Acid, Protein, Organic Acid And Carbohydrate Changes Occurring During Germination Of Peach Seeds, Lee Chao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conditions required for seed germination are different among species. Some seed of tropical and subtropical plants may germinate before the maturation of their fleshy fruit, e.g. papaya species, while seed from most deciduous trees have a period of after-ripening before germination. The after-ripening period, also referred to as rest or dormancy has also been observed in some vegetable crops and ornamental flowers.

A Study Of The Extent To Which Further Consolidation Is Feasible And Desirable Within Selected County School Districts In Utah, Walter D. Talbot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under the mandator consolidation act of 1915, the county-unit school district in Utah had its beginning (10). Although, through this consolidation movement, many small school districts were combined into larger ones, the elimination of the small districts did not, necessarily, provide for the elimination of the small schools. Due to several factors including distance, poor communication and transportation facilities, and a strong desire on the part of the people who lived in small communities for a voice in school matters, the consolidation of school attendance areas did not keep pace with school district reorganization.

With the improvement of highways and …

The Comparative Costs Of Processing Frozen Sour Cherries, Utah County, Utah, 1964, Richard K. Hart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since 1905 when Professor Henry C. Taylor opened the area of economies of scale for discussion with his observations on the variables affecting farm size, agricultural economists have been concerned with scale of plant in agriculture. Considerable study and discussion have not resolved many of the questions raised in this area, but a basic framework has been constructed which can be used as a planning tool in the efficient organization and operation of plants of various sizes under given conditions.

Some Economic Effects Of Irrigation Water Pumping From A Declining Water Table In The Milford Area Of Utah, Duane R. Price

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface water is found in very limited quantities in most of southwestern Utah. In order to compensate for a deficit of surface water it has been necessary to use underground water where it is possible and profitable to do so. The Milford pumping area in southwestern Utah is an area where expanded irrigated agriculture has been established by pumping of ground water. It is one of four major pumping areas in the state of Utah.

Navajo Student Food Preferences, Kathlyn L. Coffman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adapt -- “to make suitable to requirements; adjust or modify fittingly." Adaptability is a trait which has been attributed to Navajo Indians by anthropologists, educators, novelists, psychologists, artists -- in fact, by almost everyone who has had dealings with them over a period of time. Yet, to identify specific examples of their adaptability and the attempt to measure the effect upon interpersonal relations of evidences of adaptation has proved to be no easy task.

The Inhibition Of Water Uptake In Sugar Beet Roots By Ammonia, Darrel Marshall Stuart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various ammonium salts, urea, aqua ammonia, and anhydrous ammonia are important sources of nitrogen for the fertilization of agricultural crops. While ammonia and its compounds are useful as fertilizers, they can be, and often are, toxic to many plants (Willis and Rankin, 1930; Stout and Tolman, 1941; Raleigh, 1942; Stoll, 1954; Lorenz, 1955; Grogan and Zink, 1956; Allen, 1962; Cooke, 1962; Allred, 1963; Court et al, 1964; Hood and Ensminger, 1964). There are also products which have been designed to retard the oxidation of ammonia and its compounds (Go ring, 1962). It is therefore important that the effects of ammonia …

The Influence Of Soil Moisture Regimes And Atmospheric Environments On Transpiration And The Energy Status Of Water In Plants, Sampatrao A. Gavande

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant responses to different soil moisture regimes have been extensively studied. Because of interactions between the soil, plant and climatic factors, few convincing generalizations concerning the influence of soil water on the transpiration of water by plants have been established. Generally single factors or at most the interaction of two have been studied at any one time. Useful theories describing the conditions of water retention in plant tissues and movement of water through plants have been proposed. Equally useful theories have been suggested for describing the retention and transmission of water in soil. The integration of these theories and their …

In Search Of The Elizabethan Woman, Melba Mcdonald Burrows

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The modern woman, who analyzes every detail of her existence by means of the written word, finds the Elizabethan woman an enigma that defies a satisfactory solution. She received the finest education available in her day, and she lived during some of the stirring events in English history; yet she has left us almost no written record of her personal life and her attitude toward the world she knew. We catch glimpses of her materialistic life in the detailed accounts in which she recorded the financial transactions affecting her husband’s properties, but we do not know how she regarded the …

The Identification Of Basic Problems Found In The Bassoon Parts Of A Selected Group Of Band Compositions, J. Wayne Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the early sixteenth century, the bassoon has played a role of varying importance in musical organizations. Early groups used as many as twenty-four bassoons in conjunction with other instruments. Today, it is common to have no more than two or three bassoons in bands and orchestras because other instruments, as they developed, have replaced the bassoon in the instrumentation of such groups. Although the bassoon is not as important numerically as it formerly was, its place in musical organizations is assured because it has expressive colors and tonal qualities which cannot be duplicated by any other instrument. The bassoon …

The Dynamics Of Duopoly, Gordon E. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A monopolist, knowing the demand curve for his product, can in a given period produce the quantity of this product which will maximize his profit. Any larger or smaller quantity will result in less profit. When another manufacturer starts producing the same or similar product, a duopoly result. The new manufacturer, in order to maximize his profit, according to Cournot, will choose a quantity that is derived on the assumption that the original manufacturer's quantity will remain fixed.

Transfer Restrictions And Misallocation Of Irrigation Water, Herbert H. Fullerton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water is among the most abundant of all materials known to man. In all its various forms, water covers 75 percent of the earth's surface. It is estimated that the total physical quantity of water on the earth is 326,000,000 cubic miles. This apparent abundance belies the true nature of the water resource as it relates to the needs of man. At any given point in time, only a rather minute portion of this vast quantity of water is found in those forms and locations which render it useful to man. This may be attributed to the fact that utility …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research and development (R&D) play an increasingly important role in the economy of the United States. Total expenditures for R&D during the decade of the 1950's were greater than in the entire history of the United States previous to that time. As a percent of gross national product, R&D has grown from 0.2 percent in 1921, to 0.4 to 0.6 percent in the 1930's and 1940's, and is now more than 3 percent.¹

Much has been said of the impact that the growth of R&D has on the general economy. R&D had also had a significant economic and sociocultural …

Simultaneous Flow Of Heat And Water In Plant Tissue, Gaylon Sanford Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although biological phenomena may be partially described in a general way without the use of mathematics and physics, the experimental results may be more meaningful if they are analyzed on the basis of physical and mathematical laws. The complexity of biological systems has made the application to them of mathematics and physics rather difficult, and only recently has much progress been made. Although it has yet been possible to describe only a few simple biological systems by actual equations, a great deal of qualitative information may be obtained by applying physics and mathematics. Russell (1960, p. 439) said

In principle …

Recently the use of nitrogenous fertilizers has increased manyfold. In view of the importance of this element in crop production, even greater use is anticipated in the coming years. In order to make full use of the applied nitrogen, continued investigations of soil-nitrogen relationship are imperative; however, this element presents many complex and challenging problems to investigators.

The Complex Formation Of Silver Ion With Ribonucleic Acid, Guanosine, Inosine And Related Compounds And Peroxidase-Like Activity Of A Haemundecapeptide Prepared From Horse Heart Cytochrome C, José Angel Reinosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of nucleic acids in plant and animal cells as carriers of genetic information and as protein biosynthesis agents is well recognized. It is also known that nucleic acid is a component of all viruses.

Takahashi (45) and Fraenkel-Conrat (16) demonstrated that the protein component of tobacco mosaic virus is non-infectious to the host plant, although it is identical to the original virus morphologically. The virus ribonucleic acid (RNA) alone was infectious, however.

Deoxyribonucleic acid (DNA), which is present in chromosomes, displays a very specific function. The chromosome long has been accepted as the carrier of the hereditary unit, …

Physio-Chemical Changes In Relation To The Rest Period Of Peach And Apricot Trees, Hussein Ibrahim El-Mansy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many plants require exposure to low temperature for a certain period during each year. This was determined more than a century ago. Understanding this phenomenon, known as the rest period, is part of a larger problem of understanding the factors which determine the ability of an organism to grow. The property of rest is ultimately a property of the actively growing cells, rather than that of the cells involved with protection and support.

The Effect Of Soil Adsorbents On The Thermodynamic Properties Of Soil Water System, Taghi Manbeian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been generally recognized that the surface phenomena of the solid particles such as shrinking and swelling, water- holding capacity, water' movement, and cation exchange are important in understanding the physical properties of the soil. Clay is the most prevalent material in the colloidal fraction of many soils. Because of the complex nature of the surface of clays and the small size of the particles, the direct study of surface phenomena is difficult. Thermodynamic functions change in accordance with changes and organization within the system. Thus, an examination of the thermodynamics of surface phenomena provides some understanding of the …

Considerations Influencing Utah Farmers In Their Decisions To Produce Sugar Beets, Surjit Singh Sidhu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sugar has been an important commodity down through the ages. In the present day world, there is hardly any corner of the world where sugar is not consumed in one form or another.

Wide variation in per capita consumption of sugar exists among nations. Sugar consumption appears to be related to income level. Sugar in the United States is considered an item of necessity, and its consumption is relatively stable. This is evidenced by low price and income elasticities of demand for sugar which were -0.28 and 0.27 respectively for the period 1921-1956 (1). Consumers thus consume about the same …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Physical education is included as a part of the curriculum in most secondary schools throughout the United States. Since it is usually required for at least one year, and possibly more in some schools, it is important to design the program properly. A well-rounded physical education program is established to include three phases: the instructional phase, the intramural phase, and the extramural phase.

Saponin Content And Some Pod And Blossom Characteristics Of Alfalfa As Related To Seed Infestation By The Alfalfa Seed Chalcid, Ronald D. Morse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa seed chalcid, Bruchophagus ruddi Guss., is a jet-black hymenopteran wasp. The destructive nature of this pest has been recognized since the latter part of the nineteenth century. Every year thousands of acres of alfalfa seed are destroyed, with infestation reaching as high as 8 5 percent in some areas. In Utah the chalcid annually ruins from 5 to 25 percent of the alfalfa seed. Much of this damage goes unnoticed, as infested seed is commonly blown out in the trash during harvesting and cleaning operations . The extent of damage is not restricted to the United States. Wherever …
