The Effect Of Injected Radioactive Phosphorus On Some Phases Of Reproduction In The Albino Rat, Arland E. Olson

Biology

Damage to the germinal tissue of the ovary by radiation was reported in 1905 by Halberstaedter and by Bergonie and Tribondeau (2). These workers stated only that X-irradiation of the ovary injured the organ and resulted in a marked decrease in size. In 1913 Lacassagne (2) reported the effects of X-irradiation on the ovary of the rabbit. After intensive study he reported that the ovary might be made sterile for a time but that recovery could take place. Primitive ova not killed at the time of irradiation would develop, and the animal could give birth to living young. Since these …

A Comparison Of Methods For Differentiating Sources Of Fecal Pollution Of Water, Russell S. Fraser

Biology

Winslow and Palmer (1910) stated: "Sanitarians are continually seeking and seeking in vain, for some criterion by which sewage pollution of human origin may be distinguished from surface wash and agricultural land," and conclude their study of intestinal streptococci by remarking that: "...the use of mannite broth as a differential test for streptococci of human origin would seem sufficiently promising to warrant further study."

The Cinnamon Teal (Anas Cyanoptera Vieillot): Its Life History, Ecology, And Management, Howard E. Spencer Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It takes but a perusal of literature pertaining to waterfowl to realize the paucity of information regarding the Cinnamon Teal. The Redhead, Blue-winged Teal, and Canvasback have all been exhaustively studied by Low (1941). Bennett (1938), and Hochbaum (1944), respectively; and other species are now receiving attention from other workers. In order to help round out these studies of particular species, the writer undertook the project of a detailed study of the life history, ecology, and management of the Cinnamon Teal.

A Study Of The Campus Recreation At Utah State Agricultural College, Tod V. Carlini

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance and growth of campus recreation is being felt by leaders throughout the country. Daniels (2, p. 38) summarizes the importance of the total organism in modern education as follows: "Ample justification for a consideration of, the problem of recreation may be found in the latest and most authoritative literature in the field of educat1on, as well as in a direct study of conditions found on many college campuses throughout the country. Rooted firmly in the philosophy of modern educatlon is the thought that the total organism must be given the opportunity for experiences of an all-round nature, with …

Cost And Efficiency Of Producing Canning Peas In Cache And Box Elder Counties, Utah, 1951, Lynn Herman Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The production of canning peas has an important place in the economy of Utah, particularly in the counties along the western slopes of the Wasatch Mountains. The enterprise is one which adds intensity to Utah's small farms. This intensification is accomplished with little additional equipment or labor other than that owned or supplied by the farm operator and his family. The crop is seeded in early spring and harvested in early summer leaving the ground available for summer fallowing or planting to a short season crop such as grain pasture. Peas are a satisfactory nurse crop for small-seeded legumes such …

Inheritance Of Ten Characters In Barley Crosses, Hazim Ahmed Al-Jibouri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inheritance of many characters in barley has been studied, and two or more genes have been located in each of the seven pairs of chromosomes. Studies of the mode of inheritance of these characters will aid plant breeders materially in working with plants of diverse genetic make-up. Hybridization followed by selection and testing can improve present varieties by replacing them with new ones having more desirable characters.

Barley (Hordeum sp.) is one of the few species of plants widely distributed which is well adapted to genetical analysis. This plant has a lower number of chromosomes, complete self fertility, and a …

Industrial Arts In Utah--Its Introduction And Development, Charles W. Hailes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For the past few years many questions have been asked about the growth and development of the industrial arts program in Utah. Many of these questions could not be answered by leading educators. Thus, it is hoped that with the information presented in this report enlightenment may be given to unanswered questions.

The roots of present-day concepts and practices of industrial arts in Utah extend back about fifty years to the first schools established by the Mormon pioneers. The first school, in its simple setting, faced such issues as: What kind of industrial arts training shall be provided? How much …

The Influence Of Time And Rate Of Application Of Urea Spray On The Yield And Protein Content Of Winter Wheat, Vern L. Marble

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Winter wheat, with an annual average acreage of about 300,000 acres, forms an integral part of the farm economy of Utah.

For many years intermountain agronomists and farmers alike have known dry-land wheat production to be limited by low summer rainfall. In the past 15 years, however, it has become apparent through intelligent research that in many cases lack of nitrogen has been the limiting factor. When this occurs, winter wheat production can be increased by correcting this nitrogen deficiency

An Analysis Of School Drop-Outs At Tooele High School, Franklin Whitehouse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study of approximately 50 early school drop-outs is an effort to find out why so many boys and girls leave school before they complete their high school course. We need to know the basic reasons that prompt their decisions, not the superficial excuses that appear on many school records. The study was undertaken in the belief that when the causes are understood, they can be remedied through measures to provide adequate programs of student aid. If it is because of lack of interest in school, this, too, can be remedied through changes in school programs to make them mean …

Relative Curricular Emphasis In Some Utah High Schools During The 1941-1951 Years, Edward W. Payne

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To have a sound and complete philosophy of education is a relative must for all people concerned with the teaching of children. Fortunate is the school whose administration and faculty have in common a functional definition of the term "curriculum" and its place in their total philosophy of education. The school program of only a few decades ago consisted of the strict disciplinary type of teaching, with only a few available subjects which were intended to develop the total capacities of the student. The new philosophy recognizes the variation in students as individuals. One must not assume that there is …

The Effects Of Fertilizers On The Yield, Carotene Content And Tocopherol Content Of Ranger Alfalfa Hay In Utah, Charles Wm. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is generally regarded as one of the world's most valuable cultivated forage crops. Few crops, if any, are equal to it in capacity to produce heavy yields of highly nutritious, palatable feed. A combination of desirable attributes as a forage plant and adaptation to a wide diversity of soil and climatic conditions has led to the use of alfalfa in the world to an extent probably exceeding that of any other single legume or grass. Alfalfa constantly proves itself as a valuable feed for most types of livestock. This is especially true in the states where a large amount …

Salt Movement And Forage Crop Establishment In A Saline-Alkali Soil As Influenced By Ridges And Furrows, Sprinkler Irrigation, And Soil Amendments, D. C. Purnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimated two to four million acres of irrigable saline and alkali soils of the United States return very little income to land owners (17,19). Increased needs for forage crops, and the relatively high salt and alkali tolerance of some improved forage species, once established, suggests a way of increasing revenue from some of these lands without costly reclamation.

(b) The …

The Influence Of Temperature Gradients On Soil Moisture Flow, Luigi Cavassa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The isothermal movement of liquid water in saturated soil has been intensively studied, and a sound theoretical basis has been developed. Considerably less is known about the flow of water in unsaturated soils, but a general theory based on Darcy's law of flow is beginning to develop. A good theoretical basis exists for the vapor diffusion under isothermal conditions. Inconsistent data and theories are found in the literature concerning the movement of water in both the vapor and liquid phases, under the influence of thermal fields.

Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildlife management has been defined as lithe manipulation of wild populations of vertebrate animals in their relation to man and his interests" Wildlife management, then, could not exist in the absence ot either wildlife or humans. Converting this idea to the waterfowl situation, we can say that there are no waterfowl problems other than as they exist in the minds of men. (Wil1s, 1951) These words by the Chief of the IllinoIs Natural History Survey precede a plea for fundamental facts and a basic understanding of waterfowl upon which sound management can in turn be based. l"or only through sound …

The Total Surface Of Some Soils As Related To Permeability And Water Retention Characteristics, Warren W. Rasmussen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that many of the chemical and physical properties of soils are dependent upon the surface activity of the finer soil fractions. The importance of the magnitude of the surface areas to such properties as base exchange, water-holding capacity, absorption of gases, and the plasticity of soils has been demonstrated. Attempts have been made to determine or estimate the surface of soils and soil fractions by various methods and to relate the values obtained to the physical and chemical characteristics exhibited by these materials. Most determinations have been based on calculations of surface area from mechanical analysis …

Drainage Of The Logan-Hyde Park-Benson Area, Utah, Gordon H. Flammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

B.A. Etcheverry (4) in his book, Land Drainage and Flood Protection, states that inadequate drainage causes: (1) a public health menace, (2) an animal health menace, (3) lower grade plant life, (4) inadequate soil saturation, (5) lower soil temperatures, (6) shallow root penetration and, therefore, plant suffering in late summer months from effects of drought, (7) poor soil texture and workability, (8) increased surface washing and erosion of land surface, and (9) alkali and saline conditions. Other factors such as poorer roads and highways, decreased tax revenues, etc., might be added to this list. The advantages of adequate drainage …

Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Little is known of the relationships between livestock grazing and duck nesting. This dearth of information occurs in spite of the fact that an understanding of these relationships is necessary in order to evaluate duck production on range land, and to formulate grazing policies for lands devoted to the production of ducks.

Recognizing the need for information on this subject, the Utah Cooperative Wildlife Research Unit and the Wildlife Management Institute jointly sponsored a study, during 1948-1949, of livestock grazing-duck nesting relationships in the saltgrass vegetation type in northern Utah. The study was financed by the Institute and supervised by …

A Linkage Study Of Chromosome Iv In Barley, Earl William Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley (Hordeum sp.) is a principal cereal crop throughout much of the world and is of great economic importance in the United States. Spring barley is a leading cereal crop in Utah.

Barley has many desirable characteristics which make it an excellent plant for genetic studies. Some of these characteristics are low chromosome number, almost complete self-fertilization, relative ease of hybridization, and easily classified hereditary characters.

The establishment of genes or factors at definite loci in linkage groups is a valuable aid in furthering breeding programs and the ultimate improvement of barley. All seven linkage groups have been established …
