A Study Of Detachment Of Soil By Artificial Rainfall And Its Relation To The Dispersion Ratio And Water Stable Aggregates For Nine Utah Soils, Pundlik N. Kalbhor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of soil erodibility has become of paramount interest in the last few decades. The effects of soil erosion are serious and extensive and affect nearly all people.

In general, man can do little or nothing about the geologic erosion or natural erosion in which the processes of rock weathering and soil erosion gradually wear down the earth's surface. However, human disturbance of the natural conditions of the land surface often creates accelerated erosion. Fertility of eroded soil is usually reduced measurably and crop yields are lowered considerably as erosion removes seed soil nutrients and cover crops. Loss of …

Ferrilegoglobin As An Oxidizing Agent For Hydrazine, Donald B. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The system in which atmospheric nitrogen succumbs to enter Nature's cycle has a yet proven evasive with respect to the actual chemical reactions. At present several types of systems are proposed but their chemical makeup is practically unknown.

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 …

An Evaluation Of The Salt Tolerance Of Selected Clones Of Agropyron Elongatum, Jordan G. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt-affected soils make up much of the bottom-lands of the arid and semiarid areas of the western United States and are especially prevalent in irrigated regions. Such soils require special remedial measures, management practices, and salt tolerant crops if they are to have economic value.

A Survey Of The Use Of Standardized Tests In The Junior High Schools Of Weber County, Ashlaug J. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is evident from the literature reviewed that there is a need for better understanding and utilization of standardized test results. It seems that unless tests contribute to the learning process they are not justifiable. Merritt (12, p. 66) says the main objective of all endeavor is to promote learning. Ultimately, the worth of any activity carried on in the schools has to be judged by the contribution this activity makes toward the improvement of learning. Testing is no exception. In a broad sense, desirable learning has taken place when behavior has been changed in socially approved directions. Testing is …

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 …

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 …

A Study Of The Sequence Of The Professional Education Program For Elementary School Teachers At Utah State University, Christopher Lee Colston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education, like any other profession, is responsible for constant improvement. The professional teacher education institutions are constantly looking for ways of improving professional teacher education programs. The course sequence of the teacher education program is an area for continual improvement. Every teacher educator has a theory as to what is the best teacher education program and what is the best sequence for this theory program. The literature has revealed very little in the area of a sequence for the teacher education program.

A Study Of Two Groups Of Superior Students At The Logan Junior High School, Rudgar H. Daines

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Educators have long been aware of the varied needs, abilities, and interests of children. They have tried to provide proper curriculum, materials, and methods to meet the wide range of abilities that exists in every classroom. Despite the attempt of the schools to provide for the particular needs of the individuals, the gifted students continue as a neglected segment in our schools. Because of other pressing educational problems, the awareness of their needs has been somewhat pushed into the background, and only through the present demand for greater leadership in our country and for the optimum use of our manpower, …

An Application Of A Thermodynamic Flow Equation To Water Movement In Unsaturated Soil, Brennan Derry Soane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movement of water in soil presents many interesting problems to the research worker. It is also a subject which finds wide and important application in agriculture and several branches of engineering.

The object of this work was to examine the usefulness of a new equation of flow of water in unsaturated soil. If valid, this new approach may be able to eliminate some of the gaps in our present knowledge of the subject.

All soil lying above the capillary fringe of a water table is in the unsaturated state with respect to water. This means that in any macroscopic …

Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

The Phytoplankton Of The Logan River, Utah, A Mountain Stream, William J. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The voluminous limnological literature contains few studies of mountain streams. Though there are a few papers on the benthic algae (see Budde 1928, Raabe 1951) only Pennak (1943) reports year-round quantitative data on the phytoplankton. Brinley (1950) gives some phytoplankton information in a summer study of streams in Rocky Mountain National Park.

Morphological, Chemical, Histological, And Sensory Quality Changes In Gamma Irradiated Carrots And Potatoes, Keith Andrew Madsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Through the ages, people have been confronted with the problem of storing food after the harvest season for consumption during the winter months. Foods have been preserved by dehydration, canning, and refrigeration. However, people usually prefer fresh vegetables become unfit for human consumption as a result of sprouting and breakdown in storage.

Some chemicals have been used with various degrees of success in preventing sprouting of certain vegetables. The chemicals were applied as a pre-harvest foliar spray or directly on the tubers or on the roots.

In 1954, a law was passed by the United States Congress authorizing the release …

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 …

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 …

Thermodynamics Of Phosphate Absorption On Several Charcoals, James Duncan Beaton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus has long been recognized by agriculturists as being one of the elements essential for plant growth. Although the total phosphorus content of a soil may be high, the amount of phosphate actually available for plant growth is often low. Many agencies such as inherent low solubilities of phosphate compounds, adsorption on Ca C03, adsorption in the diffuse double layer of clay micelles, and chemical precipitation of phosphate which refers to the removal of phosphate ions from solution and their chemical bonding to the solid phase have been studied to explain the lack of phosphate availability.

The Relative Saponin Content Of Alfalfa Varieties In Utah As Measured By Chick Growth Depression, Morris Dean Wilding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bloat among ruminants is not new to farmers or scientists. One learns from a Roman author's description of this ailment written in 60 A. D. that the symptoms have changed little since that time. Literature also records that the treatments used today for the prevention and relief of bloat are similar to those prescribed by the early Romans (Anonymous 1954).

Combining Field Fertilizer Trials With Soil Tests In An Effort To Obtain The Most Suitable Soil Nitrogen And Phosphorous Tests For Southern Alberta, Einard Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under dryland farming operations, the use of fertilizers is often restricted due to limited crop response arising from limited seasonal moisture. Once this dryland area is brought under irrigation, there is increased use of fertilizers and increased demands for greater exactness in amounts of fertilizers to apply, due to efforts which are made to increase the returns from the land by introduction of new farming techniques and crops.

A Survey To Determine The Incidence Of Antibodies Against Q Fever In Persons In Utah, Carl H. Blank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Q fever, as a recognized clinical entity, is often referred to as a new disease of man. Pneumonic in character but lacking clean-cut pathognomic characteristics, in all probability Q fever has been confused in the past with influenza, primary atypical pneumonia (1), or included as an undifferentiated disease under "virus pneumonia." Geddis Smith (2), writing in 1941, stated:

...influenza, pneumonia, "pleurisy", or bronchitis ... form a nosological jungle in which bacteria and viruses roam at will, despoiling the human race and defying both classification and control. Symptoms overlap and no one knows how many different diseases lurk behind them.

The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

A Follow-Up Study Of Utah State Agricultural College Graduates In 1948, 1951, And 1954, Who Obtained Secondary Teaching Certificates, Wendell Blair Low

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many educators consider the shortage of qualified teaching personnel as one of the most serious problems in education. In the past this shortage has been primarily confined to the elementary level. However, the United States Department of Education states:

Long-run forecasts of population indicate that employment of secondary teachers should be higher throughout the forty-year period 1960-2000 than in 1950. The long-range trend for a rising proportion of young people to attend high school is expected to continue. Greatly increased Federal and State aid to education might expand enrollments considerably. The trend toward enriching curriculum, offering special subjects, and extending …

Seasonal Distribution Of Mosquitoes In A Mile-Square Area West Of Logan, Utah, Takeshi Miura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mosquitoes are one of the most important groups of insects, because of their blood-sucking habit and their ability to transmit a number of serious diseases, such as malaria, yellow fever, dengue, encephalitis, and filiariasis.

The most important mosquito-borne disease in Utah is probably equine encephalomyelitis, which is a serious disease in man, horses, and mules. According to Spendlove and others (1953), this disease occurs every year in Utah:

Cases among horses usually are scattered, but severe horse epidemics in past years have destroyed hundreds of animals. Since this disease in humans is difficult to distinguish from other similar diseases, such …

The Biology And Seasonal Distribution Of Eucalliphora Lilaea (Walker) In Cache County, Utah, Robert P. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of: flies with man has been recorded through many centuries. In nearly all of these records the association is one of discord rather than harmony. In the Book of Exodus, 8:24, in the King James version of the Old Testament, we can read, "...and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was corrupted by reason of the swarms of flies." Centuries later the "grievous swarms of flies" 'were associated with a particular disease by Mercurialis. In 1577 he expressed the …

Union High School is located in Roosevelt, Utah, on the Uintah and Duchesne county line.

Students come to Union High School from an area of approximately 30 miles radius around Roosevelt. Included in this area is the Ouray and Uintah Indian reservation.

There are approximately 125 full-blood and mixed-blood Indians who should be attending Union High School. The greater majority of these students live on the reservation named above.

Since 1951, when the majority of the Ute Indian students were transferred from the Indian school, there has been a closer association of full-blood Indian, mixed-blood Indian, and white students. With …

An Economic Analysis Of Alfalfa Seed Production Costs And Returns In Utah, 1952, Jack B. Goodwin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is the most important forage crop in the United States and a crop vital to the livestock industry. It is the ideal to which other hay crops are compared. In terms of total digestable nutrients and as an economical source of these nutrients, it is without equal. Other features in which alfalfa excels over other hay crops as a forage are: high yield, palatability, high protein and calcium content, and value as a source of vitamins A and D (4, p. 340). In addition it has great value in soil conservation practices for controlling erosion losses and nitrogen depletion. …
