Limnological Studies On Hyrum Reservoir, In Northern Utah, Royal A. Rich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With an ever increasing fishing pressure on our natural and artificial lakes every measure possible must be taken to preserve the sport for its many thousands of participants.

Hyrum Reservoir is easily accessible to the fishermen of northern Utah. In recent years the lake has offered little in the way of fishing. It is hoped that the information accumulated in this study will help pave the way to a successful stocking program and that Hyrum Reservoir will be one of the productive fishing areas available to Utah anglers.

The objectives of this investigation were:

1. To determine the extent of area …

Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The channel catfish, Ictalurus punctatus (Rafinesque), was first introduced into Utah Lake in the summer of 1911, and has since been stocked in the lake on numerous occasions. It has only been in the last few years that the channel catfish has become an important game fish in Utah. As the value of the channel catfish, as a game fish, increased, it has become increasingly important to the state to maintain this species for present and future generations. This study was initiated in 1958 and completed in 1960, and was financed by the Utah State Department of Fish and Game. …

The Effects Of Flouride Ion On Some Blood Constituents Of Rainbow Trout, Salmo Gairdneri, Linnaeus, Richard H. Alger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past quarter of a century there has been considerable investigation into the effects of fluorides on living organisms. It has been well established, as a result of these studies, that both small and elevated amounts of fluorides present in the environment may have a marked toxic effect upon gaining entry into the organism. Much of the research involving fluorides and the living organism has been confined to experimentation with animals, although considerable evidence indicates that plants are also subject to injury if fluorides are present in the atmosphere or the soil.

The great majority of the research dealing …

Interaction Of Riboflavin With Molybdenum, Jacques Tocatlian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum may function as a catalyst in promoting and controlling some of the complex chemical reactions that go on in living systems. The lack of understanding which exists about these reactions is due to their obvious complexity and to the extremely minute quantities of molybdenum involved. Traces of molybdenum have been shown to have spectacular results on the growth of plants when added to certain soils. This metal is also required for the growth of azobacter, the nitrogen-fixing bacteria (1).

Molybdenum has been shown to be present in four enzymes: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4) and aldehyde …

Life History Notes On The Walleye, Stizostedion Vitreum Vitreum (Mitchill) In A Turbid Water, Utah Lake, Utah, Billy B. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early in 1952, walleye fry were stocked for the first time in Utah Lake. Subsequent plants were made in 1954, 1955 and 1956. Altogether, over two million fry have been stocked.

By January, 1958, it was felt sufficient time had elapsed for the species to establish patterns of growth, reproduction, food habits and consequent relationships to the new environment. Thus, on January 1, 1958, a Federal Aid to Fisheries project, number DJ F-4-R-5, job T, was initiated. This project was entitled "investigations of Yellow Pikeperch and Channel Catfish of Utah Lake, Utah County." Although the closing date was December 31, …

The Effect Of Feeding Various Levels Of Fluoride To Dairy Cattle On Their Pepsin Activity, Hassan Sabeti-Rahmati

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In certain industrial areas fluorides are present in various amounts in the atmosphere. These fluorides are liberated by industrial processes at high temperature in treatment of materials containing fluoride, either as a natural impurity, or as added material for technical purposes. Equipment and procedures have been installed in many plants to reduce the output of fluorides significantly, yet forage and hay grown near the plants may contain elevated amounts of fluorides. The feeding of such material to young livestock for many months may cause fluorosis or chronic fluoride poisoning. Some springs contain a high concentration of fluorides and the continuous …

Studies In Iron Chlorosis Of Leaves, Narayan Gunderao Perur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.

When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant …

A Political Study Of Federal Aid To Education At Utah State University, Richard Yates Merrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the present-day world of change, every time we pick up the paper we read of something new in our society. We now have new rockets, new satellites, new computers, and new methods or destruction. There are also many "new" things in the field of education. One of these is federal aid to education. As yet, there seems to be no consensus on the merits of this supposedly new approach to educational finance. Some view it as a kind or plague; others see it as an unmixed blessing. Actually, federal aid to education is quite old and quite common.

A Comparison Of Daughters Of Sires In Artificial Breeding At Different Levels Of Management, Richard C. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the largest problems facing the successful dairyman of today is selection of proper sires to mate to his high producing cows. Many breeders and dairymen have the impression that proven sires will give the same increase in production regardless of the dam's production or the level of environment present. Even though sires come from high producing herds, some as high as 600 pounds of butterfat, the average production of all cows in the state of Utah remains at a much lower figure. The average for all cows in Utah is about 250 pounds of butterfat and the average …

A Study Of Hot Brine Treatment In Making Cheese From Antibiotic Milk, Robert E. Howe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cheddar cheese industry is continually confronted with the problem of manufacturing cheese from milk in which tile acid development is slow or non-existent. In recent years, many antibiotics have been used as a treatment for mastitis. Penicillin, streptomycin, and aureomycin are some of the more prominent antibiotics used for this purpose.

Artificial Pothole And Level Ditch Development As A Means Of Increasing Waterfowl Production, Charles H. Lacy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The glaciated prairie pothole country of the Midwest forms a vital segment of the most important waterfowl breeding habitat in North America. Here are hatched three-quarters of all the ducks raised in the United States. During a recent seven-year period the three-state area of Minnesota and the Dakotas produced an average of 4 to 5 million ducks annually (Janzon, 1947). This wetland region which once comprised 115,000 square miles in five states had shrunk to about 56,000 square miles by 1956 (Lynch, 1956). To maintain the present rate of waterfowl production in the face of continued destruction of habitat through …

Motor Truck Transportation Of Cattle In Utah, Loren H. Grover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The beef cattle industry in Utah is of major importance in the economy of the state. In terms of cash receipts it is the largest single agricultural enterprise. In 1957 cash receipts from the sale of cattle and calves amounted to $38,405,000. This figure represents approximately 70 percent of cash receipts from the sale of all meat animals. It comprises 33 percent of cash receipts from the sale of livestock and livestock products and 24 percent of total cash receipts from farm marketings (2).

The production of beef animals will continue to assume a position of importance in Utah's agriculture, …

A Study Of Delayed Gas Formation In Cheddar Cheese, Mark E. Oldham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During recent years, the dairy industry has been aware of a defect in Cheddar cheese known as "late gas". This causes the mechanical openings to enlarge and become shiny. In Cottage cheese the defect exhibits itself in a general lowering of the grade and quality of the finished product.

Workers in the industry have related this defect to the starter culture, although contamination of milk, equipment and cultures may also be a source. They conclude that with a source of good quality milk and proper manufacturing procedures and efficient sanitation methods, the defect may persist.

Whichever source the defect stems …

A Historical Study Of Plain City, Weber County, Utah: Community Background As An Influence On Education, Fern Olsen Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problem. The problem in the study of the history of Plain City was to show that community backgrounds do affect the lives of individuals. Greater social achievement can be attained within the framework of a good foundation in education, a solidarity of home life, a respect for mankind and attention to religious beliefs.

Lethal Concentrations And Detoxification Time Of Toxaphene For Goldfish, Gambusia And Rainbow Trout, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past few years the Utah Fish and Game Department, as well as the fish and game departments of other states, has been spending fisheries money for fish eradication on both lakes and streams. The Utah Fish and Game Department recently suggested to the University that research be initiated on the subject of toxaphene as a fish poison. Consequently, a better insight into conditions that exist for a given water type could be developed.

The Biology Of The Utah Chub, Gila Atraria (Girard), Of Scofield Reservoir, Utah, Harold F. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah chub is one of the most important non-game fish in Utah. It has a wide range, and occurs in every drainage in Utah. The Utah chub is not important economically as food fish nor is it of much value commercially. The sportsmen think of this species as trash and do not consider catching or consuming them. However, the Utah chub may be caught on hook and line more readily than many game species. The Utah chub in Scofield Reservoir have been caught by trolling, bait fishing and fly casting and furnish considerable sport when caught with a light …

A Method For Determining Proteinase Activity, Bhupendra V. Randeria

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enzymes play a very important role during the ripening process of the cheese. Enzymes are important in producing the body, texture, and flavor of the cheese. The breakdown of carbohydrates, fats, and proteins by added enzymes into different end products during the ripening of the cheese aids the process and may reduce time. The characteristic flavors of different varieties of cheeses are influenced by enzyme action. Some enzyme like proteinases can be used to improve the body, texture, and the flavor of the cheddar cheese. Addition of these enzymes during cheddar cheese making may shorten the ripening period. In order …

Feeding Protein, Phosphorus And Energy Supplements To Beef Cows On Utah Desert Ranges, Robert Hyrum Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many of the beef cattle in the Great Basin area are maintained part or all of the year on rangelands. Most of those going on to desert ranges for only part of the year go on during the late fall, winter, and early spring. It is estimated that 50-60 percent of the 600,000 beef cattle grazing on range lands in Utah graze on the one-fourth million acres of desert or semi-desert sometime during the year.

The Use Of Protease Enzymes In The Manufacture Of Cheddar Cheese, Osamu Fujiwara

An Ecological Study Of The Bottom Fauna Of Bear Lake Idaho And Utah, Earl W. Smart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In evaluating the potential ability of a lake to produce fish, probably no single standard is so important as an estimate of the amount of bottom fauna (Deevey and Bishop, 1942).

The study of the bottom fauna of Bear Lake was a part of the investigation of its limnology and fisheries, begun in 1952. This study was sponsored through federal monies made available through the Dingle-Johnson Act. The primary purpose of the study was to examine all the evidence in estimating the fish producing capacity of the lake. Bear Lake is the second largest fresh water lake in Utah but …

Cost Of Marketing Utah Lambs At Alternative Markets, Norman E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of lamb marketings

The production and marketing of lambs is important in Utah's economy. In 1956, Utah ranked fifth in the United States in lambs produced and saved, with 1,038,000 head produced and 840,000 marketed for consumption, table 1. Cash receipts from the lamb marketings during the year amounted to over 10 million dollars, and in addition, the state's economy benefited through revenues, employment, and raw materials which were provided by the lamb industry.

Marketing decisions

Lamb producers and handlers are faced with many decisions in marketing their lambs. They not only must decide when and where to sell, …

Linkage Relationships Of Located And Unlocated Genetic Testers In Certain Normal And Translocation Stocks Of Barley, William Ralph Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is an economically important cereal crop throughout most of the world. The study and elucidation of the genetic complex of this plant will add to its extensive usefulness to man, and will also provide valuable information for similar research projects on other crop plants.

Chlorophyll And Productivity In A Mountain River, William J. Mcconnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigation of primary production in streams and rivers has lagged behind similar investigations in marine and lacustrine environments. Recently, however, Odum (1956) has demonstrated methods that allow the estimation of productivity of most moving waters. For reasons discussed later in this paper, Odum's method is not satisfactory for shallow, very rapid rivers as typified by Logan River. The present investigation then was primarily an exploration of a method possibly applicable to measurement of productivity in shallow rapid rivers.

Investigations of phases of the ecology and distribution of the main contributors to primary production, the benthic algae, was a necessary corollary …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pollution of the atmosphere and its potential deleterious effects on health, industry, agriculture and natural resources are causing grave concern in many parts of the world. In the past century there has developed in the fields embraced by physical and biological sciences a considerable knowledge of theoretical and applied information, serving as a versatile tool in combating such problems. Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

The Agricultural Phase Of The Technical Assistance Program Of The United States In Iran, With Special Reference To The Role Of Utah State University, Malek Mansour Esfandiary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My thesis, while examining the broad scope of American technical assistance in agriculture to Iran, emphasizes the work of scientists and technicians who went there under contract with Utah State University (USAC). I have tried to make this work as complete as available information makes possible.

There are several problems encountered. Some technicians were reluctant to make comments which might appear to be critical of either the American administration or the Iranian government-cultural climate; some did not receive my letter probably because of a change of address. Reference materials were scarce. In most cases it was almost impossible to separate …

Characteristics Of Manila And Related Soil Series, Flayeh H. Altaie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In many parts of the world soils have been found that have apparently been formed under climatic conditions that no longer exist. In many places in northern Utah in areas associated with ancient Lake Bonneville, deep soils, fine-textured and non-calcareous, have been observed immediately above the highest shore line of the ancient lake. These soils have essentially no free carbonates to depths ranging from 4 to 15 feet, even though they exist on relatively steep slopes. In Davis and Utah Counties, soils having these characteristics have been given the tentative series name, Manila.

Soils studied for this thesis include one …

The Natural Reproduction Of The Cutthroat Trout, Salmo Clarki Richardson, In Strawberry Reservoir, Utah, William S. Platts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Strawberry Reservoir, Utah is an 8,000 acre lake at the elevation of 7,550 feet; it has a maximum depth of 52 feet and an average depth of 18 feet. The supply of cutthroat trout eggs used to replenish and distribute this trout throughout the state are taken from two spawning traps located on reservoir tributaries. Because it has not proven economical to raise cutthroat to a larger size than newly hatched fry, it is at this stage they are planted. Because of competition, predation, and lack of space the planting back of fry to maintain the fishery and spawning run …

A Study Of Cheese Spreads And Dips, Grant M. Steed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each year in the State of Utah, thousands of pounds of a number of varieties of bulk and packaged cheese are returned to the manufacturing plants from the stores and other distribution points. The main reasons are: broken wrapper or rind, crushed or otherwise mutilated package, and mold development.

At the present time much of this cheese is shipped out of the state for processing. The remainder is sold at drastically reduced prices. If this unmarketable returned cheese were changed in form with good consumer acceptance the industry would experience a real savings.

The Effects Of Hunting Season Length On Comparable Pheasant Populations, Temple A. Reynolds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years sportsmen have speculated that hunting limits pheasant populations. With the abolition of the Pheasant Game Farm program in Utah in 1953, this popular concept gained much impetus with the result that, because of public disfavor to a longer season, a 3 to 5 day season on pheasants is the maximum that has been called in northern Utah and this only in areas classed as "better" pheasant habitat.

In contrast to the short seasons in Utah, pheasant seasons in southern Idaho have been from 8½ to 15½ days long for the past 10 years, and will be even …

Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Staphylococcal synovitis is a pathological condition of birds involving primarily the wing and leg joints. It is frequently referred to as arthritis, osteoarthritis, bursitis, hock disease, staphylococcosis, and weak leg.

The disease has been reported throughout various parts of the world as having been found in a great variety of avian hosts including pheasants, chickens, pigeons, canaries, geese, ducks, grouse, and turkeys.

Miner (1945) presented results of a survey made on turkey diseases in Sanpete County, Utah, which indicated staphylococcal synovitis to be responsible for the greatest numbers of deaths. His report cites this infection as having been found in …
