Quality Evaluation Of Certain Fruit Jellies And Syrups Prepared With Sucrose, Sorbitol, And Synthetic Sweeteners, Sandra Louise Day

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Body weight is fast becoming the major health problem in the United States. Recent estimates of the number of weight conscious people in the United States are now up to 75 million. One year ago the estimate of overweight individuals was 60 million Americans who were overweight or should be concerned about watching their weight. There are also two million known diabetics who must control their disease and body weight by a restricted caloric intake.

A Price Analysis Of The Ogden And Los Angeles Livestock Markets For Slaughter And Feeder Cattle, 1956-1960, Jerald R. Barnard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the major objectives of every farmer, rancher, or feedlot operator is that of trying to maximize profits by marketing their cattle for greatest net returns. For this reason, it is very important at which market the producer decides to sell his cattle. Local supply and demand conditions are constantly causing prices and price differentials between markets to fluctuate, making the decision of choosing the market which will yield the greatest net return rather difficult.

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.

A Study Of The Self-Selection Method Of Reading In The Sixth-Grade Of The Ephraim Elementary School, Elliot J. Arnoldson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As educators have searched continuously for the best method to teach reading, numerous techniques have been advanced. Some of these techniques are comprised of basic elements in reading which are proven and used with much success and security on the part of the teacher. Others are tried, used, made popular for a short time and then are cast aside as in adequate teaching methods.

That learning to read is an individual matter no educator will deny. Nor is it controversial to say that, within each person's generalized reading ability, there exists unevennesses in skills development. Nor does anyone question that …

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 …

On The Enthalpy And Entropy Of Soil Water, Robert A. Kohl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Just twenty years have passed since the first papers were published on the application of chemical thermodynamics to the soil-water system (11, 14). Since then, soil physicists have used thermodynamics in an attempt to characterize and learn more about this intricate system.

A Genetic Investigation Of A Yellow Plant Color Characteristic In Winter Wheat, John Oscar Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective in wheat hybridization primarily is to obtain new varieties which are of a greater agronomic value than existing varieties. Frequently, however, crosses which obviously will not produce superior commercial types are made and studied in order to obtain genetic information which may be useful to the breeder. This latter phase of breeding, i.e., the accumulation of genetic information, provides the basis for this study.

Upper Cretaceous Stratigraphy Of The Central Part Of Utah, Fredric R. Van De Graaff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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.

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, …

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 …

The Influence Of Internal Moisture Deficit On Translocation, Sven Egenolf Wihrheim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reduced growth of plants under conditions of moisture stress has been attributed to reduced turgor necessary for cell enlargement and to reduced photosynthesis often found in wilted or moisture stressed plants. Reduced translocation is rarely mentioned as a factor in reduced plant growth under limited moisture. This is rather surprising, since the Münch pressure flow hypothesis would require a turgor pressure gradient between leaves and receiving organs before any translocation of sugars could occur. Such a turgor pressure gradient would be reduced with increasing internal moisture deficit and would appear to become zero when the leaves wilt. If this …

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 …

Ecology Of Spring Fed Salt-Marshes, Eric George Bolen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any marsh is a distinctive land-form of varied interest. To the agriculturist it is wasteland to be reclaimed; to the naturalist, a habitat of aesthetic value. To the ecologist, however, a marsh represents a complexity of vegetation under the influences of many and often inseparable factors. It becomes a place of challenging study.

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 …

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 …

Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cuterebra are robust flies, which in flight resemble large black bees. Little is known about the bionomics of most of the species included in this genus. Nearly all members of this group parasitize rodents and lagomorphs. Some species have a wide host range, others seem to be specific or semi-specific to a single host. Accidental parasitism of animals other than specific host animals does occur. In such cases the larvae or the host usually die before the larvae can mature. There is a wide variation in the effect of of the parasite on its host. If the parasite is found …

Utah's Delegates To Congress, 1851-1896, Larry Haslam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah existed as a territory for some forty-five years, 1851-1896. During these years Utah continued to occupy an interesting and controversial position on the national scene. The fact that Utah was predominantly Mormon, and that the Mormons were unusual in their beliefs and practices, made the territory and its people a target for the law-making body of the nation as well as the general citizenry. Utah was made an integral part of the congressional discussions and debates in almost every session of Congress during the period of 1851-1896, and there were repeated attempts to punish the Mormons for their "anachronistic" …

The Mineral Resources Of The Sevier River Drainage, Central Utah, David T. Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A survey of the mineral resources, the economic rock products, and the ground-water reserves of that part of central Utah drained by the Sevier River system was undertaken by the author in the fall of 1960 as a continuation of a research project directed toward the stimulation of economic growth in the state of Utah. The project was initiated in 1959 by Dr. Donald R. Olsen and Dr. J. Stewart Williams, who conducted a similar survey of a five county area in southwestern Utah (Olsen and Williams, 1960).

Through a review of existing literature, preliminary field examination of most of …

Geology Of The Summer Ranch And North Promontory Mountains, Utah, O. Clair Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Summer Ranch and North Promontory Mountains have not been studied in detail geologically, although the surrounding mountains have been extensively investigated. Within the limits of this area, sedimentary rocks of Mississippian through Permian crop out. Sedimentary and volcanic rocks of Tertiary age are also exposed. Extensive Lake Bonneville deposits underlie the valleys and overlap the foothills.

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 Aspiration Levels Of Students In Ability-Grouped And Randomly-Grouped Schools, George Aaron Jeffs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grouping students with in the school setting has long been a concern to all those associated with the educative process. Much investigation has been devoted to the position of level of aspiration as influential motive forces for educational, occupational, and social achievement. Many avenues of grouping have been investigated and some very thoroughly. However, research concerning grouping in relation to level of aspiration in the school setting appears to be extremely limited. This study is designed to further investigate this issue. It might be said that this study consists of essentially two phases: (1) the development of instruments for measuring …

A Comparative Analysis Of The Effects Of Heterogeneous And Homogeneous Elementary School Grouping Practices On Selected Personality Variables, Clarence D. Swaner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative advantages or disadvantages associated with the practice of grouping school children according to ability level has long been the subject of considerable discussion among educators. The general tendency has been for educators to divide into two camps: Those who expound the various merits of homogeneous grouping, and those who favor and support heterogeneous grouping practices. Less common, but acknowledged, are those educators who favor a combination of the two methods. Research dealing with the relative value of either method has usually been concerned with only one aspect of the problem--that of academic achievement. However, the efforts of several …

Income Adjustments From Fee And Permit Changes On Utah Cattle Ranches Using Public Ranges Yearlong, C. Kerry Gee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

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 …

Post-Harvest Storage Studies With Selected Fruits, Amrik Singh Dhaliwal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been estimated that one-fourth of the fresh fruits harvested are never consumed because of spoilage. This spoilage amounts to many thousands of tons of fruits which are valued annually at several million dollars. Several factors are responsible for the post-harvest spoilage of fruits, namely, pathological, physiological, and mechanical.

Men in the past have used various methods to control pathological spoilage of foods. The recent development of nuclear radiation, antibiotics, fungicides, and packaging films provides new methods for prolonging the shelf-life of many fruits. These may prove important in countries like India where refrigeration facilities are not readily available …

Experiments On The Origin And Nature Of A Zinc Deficiency Of Field Beans On A Portneuf Soil As Determined By The Application Of Zinc 65, Edgar Dale De Remer

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.

A Genetic Study Of Linkage And Inheritance In Barley, Jerald Dean Oldham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the exception of corn, barley has probably been used more than any other cultivated plant in genetic studies. It was one of several plants with which Erich von Tschermak-Seysenegg was working when he discovered Mendel's paper.

Barley is excellent material for use in genetic studies. It is adapted to many environments and has a large number of contrasting characters. Large populations can be grown on a small area of land in one season. It is a diploid with seven chromosome pairs. Each of these seven chromosome pairs can be identified cytologically.

There are seven linkage groups corresponding to the …

An Economic Analysis Of The Retail Raw Milk Industry In The State Of Utah, H. Kent Dewsnup

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For 98 years after the first "Mormon" pioneers entered the Salt Lake Valley there was no statewide control of the sale and distribution of fluid milk. Prior to any statewide control, however, laws were passed in Salt Lake City and Ogden outlawing sale of raw milk to final consumers in those cities as of January 1, 1945.

The Study Of The Effect Of Various Methods Of Harvesting And Curing On The Color And Viability Of Lima Bean Seed, S. G. Date

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many seedsmen have observed that lima bean seed of a variety like Early Thorogreen, which has green cotyledons, often fades in color during harvesting. This fading of color is known as bleaching. A variety which has green cotyledon and hence green seed, should retain this green color during harvest. Bleached seeds are likely to emerge slowly when planted. Also the final field stand from a planting of bleached seed is likely to be poor.

A Comparison Of Cock Pheasant Harvests Among Areas Having Different Hunting Pressures, Cache County, Utah, James C. Bartonek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parsons (1953) found Utah's posted hunting unit system regulated hunting pressures over much of the state's pheasant range. He found inequalities of hunting pressure among the posted hunting units because of their individualistic methods used to determine the number of hunting permits to be sold. Utah State Department of Fish and Game personnel recommend the number of permits to be sold by the hunting unit; but often, the hunting unit officers use the desired level of hunting pressure, size of cock harvest, and revenue from permit sales as decisive factors. By regulating hunting pressure on their own lands the posted …

Estimation Of Optimum Plot Size And Shape For Use In Safflower Yield Trials, Alfred Max Wiedemann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the big problems encountered in experimental yield trials of field crops is the variation that occurs in yield estimates regardless of how the trial is handled with respect to variety or treatment. This so-called "natural" variation is the result of such factors as heredity, human error, and environment.
