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.

Simultaneous Movement Of Water And Herbicides In Unsaturated Soils, Ming-Shyong Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since weed killers were developed in the early part of the decade beginning in 1940, herbicides have been increasing in use until they are now widely used to control weeds. The application of herbicides has thus become a regular agricultural and ecological practice.

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 …

The Impact Of Research And Development On Income And Employment In Utah, Thomas Clark Anderson

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 …

The Influence Of Organic Matter And Ph On Transformations Of Nitrites To Elemental Nitrogen, Mohammad A. Rashid

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen occupies an important and prominent place in plant and animal nutrition. Large quantities are required by plants and must be available in the soil. 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.

Movement Of Phosphorus In Soils As Influenced By Chelates And Soil Types, Abd-Elmonem Sayed-Ahmad Mostafa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problems of phosphate fertilization have attracted the attention of agronomists, nutritionists, and other biological scientists due to the importance of phosphorus in animal and plant nutrition. However, the fundamental behavior of phosphorus in soil systems is not well understood. Because of its far-reaching effects, a solution of a portion of this problem is of importance.

Nitrification In Three Different Soils In Polyethylene Bags In The Field Overwinter, William R. Olmstead

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrification, the process whereby ammonical-nitrogen (NH₄⁺ - N) is changed into nitrate-nitrogen (NO₃^--N), is one of the more important biochemical processes associated with agriculture. Nitrate appears to be the form of N that most crops can most readily utilize.

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 …

A Study Of The Extent Of Extramural Competition For Girls In The High Schools Of Utah, Betty Ann Dance

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 …

The Effect Of Protective Materials On The Overwintering Of Hardy Annuals, Candytuft And Stocks, Melvin S. Burningham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many hardy annual flowers will live through the winter if there is sufficient snow protection. Since snow cover is not consistent from year to year it has been suggested that hardy annuals planted in late summer and provided with some kind of protection before severe freezing begins will live through the winter successfully. Not only would this enable plants to bloom four to six weeks earlier, but would also enable gardeners to utilize flowers not commonly grown in northern Utah.

Some studies conducted at the Utah Experiment Station in Farmington have indicated that plants such as candytuft and snapdragons can …

An Exploration Of Test Taking Strategy With Sixth Grade Students, Mary Bates

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

The present study was an attempt to evaluate the benefits of certain cues in reaching correct answers to test questions given to sixth grade students. While it seems reasonable to assume that test-taking strategy is not as well developed in sixth grade children as in older students, this study was intended to discover if test-taking strategy would be apparent to a measurable degree at this age level. Before such an observation could be undertaken, a technique had to be devised to measure the behavior in question (in this case the use of cues). The technique used was in the form …

A Preliminary Experimental Study Of The Turbulence Decay In The Wake Of A Hemisphere In Free-Surface Flow, Jiin-Jen Lee

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

Flows observed in open channels are usually turbulent. The word "turbulent" describes a motion in which an irregular velocity fluctuation (mixing or eddying motion) is superimposed on the main stream motion. The essential characteristic of turbulent flow is that the turbulent fluctuations are random in nature.

If Reynold's rule of averaging is used, the Navier-Stokes equations for laminar flow may be transformed into the Reynold's equations, which hold true for turbulent mean motion. The solution of Reynold's equations will properly describe turbulent flow. Unfortunately, the number of unknowns exceeds the number of equations; therefore the use of mathematical method to …

Graduate Recital, Larry G. Smith

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

As long as the writer has been considering his graduate program, he has felt, because of his own peculiar limitations as a performer, that a recital project would be more beneficial to hie developing musicianship than a research and thesis project.

Strangely enough, the writer had participated quite actively for seventeen years in a most varied succession of musical organizations without having acquired that badge of authority that his successful colleagues wore so proudly: mastery of a particular instrument.

During those years, tho writer had sung soprano, alto, tenor, baritone, and bass in various choral groups, performed upon the piano, …

Graduate Recital, Neil J. Tippets

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

The author began his formal studies toward attainment of an advanced degree in November of 1961. However, the decision to perform a recital was not made until summer, 1965. The desire to improve performance abilities to the point of excellence on at least two instruments was the deciding point in favor of a recital. A more important motivating factor, related to this point of achieving excellence, was the desire to become a better teacher. It is well understood that a teacher's performance on an instrument can inspire students to become better performers. It is a necessity to be able to …

An Evaluation Of The Promotion Policy Of The Iron County Schools, Claudia J. Forsyth

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

In 1931, the Department of Superintendents, National Education Association, in their Nineth Yearbook, put "Pupil Promotion" as first in a listing of five factors needing study . In 1966, more than three decades later, the effects of promotion or nonpromotion, still remain the subject of serious consideration among educators. The problem has been the subject of research studies and many opinion articles.

The Iron County School District, Cedar City, Utah, has advocated a policy of careful evaluation for each child considered for nonpromotion . The philosophy of the district which advocates adjusting instruction to meet individual differences should eliminate, except …

Graduate Recital, Naunie B. Gardner

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

As this writer began preparation for the recital, many problems of performance began to manifest themselves, problems which are not encountered in opera or oratorio. First one must consider the problem of endurance . Would this singer be able to meet the demands of one full hour or recital performance?

Inasmuch as some of the compositions chosen seemed more demanding than others, it seemed advisable to alternate numbers which placed great physical stress upon the singer with those which allowed some moments of ease and relaxation. It is also necessary to consider significant periods and styles of vocal literature and …

Estimating Forage Production Following Pinyon-Juniper Control: A Probabilistic Approach, Terrence F. Glover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An important management practice within the 60-80 million acres of Pinyon-Juniper woodlands is to convert these woodlands to open rangelands. The success or failure of seedling adapted grasses in place of trees is contingent upon the revegetation techniques employed and upon fortuitous weather patterns. In order to formulate policy for Pinyon-Juniper control decisions, persons responsible for such policies need to know the risks of introducing range grasses into given areas. This thesis is essentially a hypothesis concerning the magnitude of such risks.
