The Influence Of An Artificial Medium Upon The Morphology Of Swine Cecal Trichomonads, Charles P. Hibler

Biology

As yet no thorough studies of the trichomonads living in the cecum of swine have been made. In fresh preparations the trichomonads from the nose, stomach, and cecum appear distinct. After a period of cultivation In an artificial medium, however, the flagellates from the cecum became morphologically similar to the cultured porcine nasal and stomach trichomonads. The cultivation of the trichomonads from the cecum apparently results in either a morphological change in the trichomonad or in a selection among different species or types present in the cecum.

The Effect Of Copper And Iron Salts On The Expression Of Eye Abnormalities And Melanotic Tumors In Different Stocks Of Drosophila Melanogaster, J. Howard Turner

Biology

Phenotypes in Drosophila can be altered by subjecting the developing larvae to environments containing an exess of heavy metal salts (34, 36). Such alterations, which resemble the effects of mutant genes but are not inherited, have been called phenocopies. The mechanism through which the phenocopy is produced may suggest a process through which a mutant gene influences a phenotype. In cases where such parallels are drawn, it is assumed that a mutant gene and an environmental agent have a similar effect on a particular step in an established metabolic pathway. It would seem less likely but not impossible for the …

Studies In Transmission In Ovine Vibriosis, William H. Rose

Biology

Vibrio fetus, Smith and Taylor, is the principle etiological agent of ovine infectious abortion in the United States. During the 1952 lambing season, the lamb abortions were estimated at 50,000 in Colorado, 30,000 to 40,000 in Idaho, and from 10,000 to 15,000 each in Utah and Wyoming. A conservative estimate of premature lamb losses due to V. fetus infections in the western states for this year was 100,000. In infected flocks the incidence of mortality in aborting ewes may be as high as 10 percent. Since 1952 the incidence of vibrosis among sheep has remained high.

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.

The Effect Of Nutrient Levels In Nutrient Cultures On The Translocation Of Foliar Applied Nutrients, David D. Neher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since man first grew crops on calcareous soils he has probably been troubled with what we today call lime-induced chlorosis. This chlorosis has determined whether he grew certain desirable ornamentals or crops or whether he had to substitute others which were less desirable.

Lime-induced chlorosis is spread world wide. It has been reported in the vine and fruit growing regions of Europe, in the chernozem soils of Russia, and many other areas where the rainfall is relatively low and the soil is relatively high in calcium carbonate. In the United States it most frequently occurrs where the average annual rainfall …

A Comparison Of Internal Bicarbonate Of Some Chlorosis-Resistant And Chlorosis-Susceptible Plants, Ralph Barlow Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron chlorosis has been a srious problem for many years. This physiological disease has occurred so frequently on calcareous soils that it has been called lime-induced chlorosis by many of the workers. Because the western United States has so many soils of this type, the chlorosis problem has been of primary concern. Untold economic losses have been the result of this physiological disease.

Interveinal yellowing of the leaves along with loss of plant vigor and retarded growth characterize the disease. In severe cases die-back of the terminal growth and eventual death of the plant result. No single factor has been …

The Influence Of Age On The Cation Exchange Capacity Of Plant Roots, Einard S. Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock …

The Effect Of Various Levels Of Bicarbonate, Phosphorus, And Ph On The Translocation Of Iron In Plants, Ronald Conrad Doney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Line-induced chlorosis is a nutritional disease affecting many fruit trees, berries, ornamental shrubs, and flowers in Utah and the western United States. In fact, this disease is of wide distribution on calcareous soils throughout the world. Lime-induced chlorosis has contributed to untold economic loss and has challenged the technical ingenuity of plant and soil scientists throughout the world. As yet the exact cause of chlorosis has not been determined; consequently, no permanent cures have been found.

The first symptoms of this disease are characterized by an interveinal yellowing of younger leaves, with the veins remaining green. In more severe cases …

The Typing Of Staphylococcal Isolates From Turkey Epizootics, William R. Thornley

Biology

Utah has been confronted with the problem of turkey synovitis becoming epizootic in certain areas of the state. This is a crippling disease of turkeys causing considerable loss among birds soon after they are placed on the range. Because much of the expense of brooding and rearing has already been encountered by the growers, the loss is often severe.

A Critical Survey Of Elementary School Playgrounds In Cache And Box Elder Counties, Thomas Cracas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the fundamental needs of elementary school children is to develop their motor systems by means of physical activities adequately suited to their representative age groups. In so doing, opportunities are provided for sociological and psychological requirements essential in developing a healthy, confident individual capable and willing to accept social and family obligations and responsibilities. This infers that an essential function of the school is to provide appropriate areas, facilities, and equipment for such activities. It also suggests that the playground be an integral element of a modern school.

The purpose of this study was: (1) to construct check …

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, …

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 …

Absorption Of C14 Labeled Sucrose By Nectaries, Cecil Wright Lefevre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the early Eighteenth Century the significance of nectar secretion has been debated. Some have reasoned that it is reabsorbed into the plant and used as energy for the developing embryo while others believe it is a waste product which attracts pollinating insects.

It has been suggested (Brink and Cooper, 1947) that the nutrient supply to developing ovules is a major factor in the development of seed. Also, alfalfa fields pollinated by pollen-collecting bees produce greater seed yields than those pollinated by nectar collectors (Bohart, Nye, and Levin, 1955). It is a well-known fact that more flowers are tripped by …

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 …

An Evaluation Of The Salt Tolerance Of Particular Varieties, Strains, And Selections Of Three Grasses And Two Legumes, Farrel John Olsen Jr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In arid and semiarid areas in the Western United States, soluble salts tend to accumulate in the soil in amounts harmful to crop production. A considerable portion of this land cannot be reclaimed due to the poor quality of permeability of the soil. Therefore, the wise selection of crops that will produce satisfactory yields on these soils in necessary.

The salt tolerance of many crop plants has been investigated; however, more information is needed on the relative salt tolerance of varieties, strains, and selections. Such information will permit the selection and development of varieties and strains of crop plants which …

A Study Of The Relative Importance Of Items Discussed In Parent-Teacher Conferences As Rated By Parents And Educators In The Logan City Schools, Robert W. Bickmore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are numerous ways, both written and oral, in which the schools can report pupil progress to parents. Promising practices include parent-teacher conferences, notes to parents, combination of narrative reports and parent-teacher conferences, and progress check sheets indicating, among other things, attitudes and behavior.

Educators have long recognized the inadequacy of the report card and the traditional marking system. Studies show that no two teachers mark just alike, even with a common set of standards to follow. Children work for marks rather than self-improvement. Marks, alone, cannot and do not tell a complete story.

The Measurement Of Physical Properties Of Field Soil, Wilbur Sloat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of soil tilled agriculture, there have been many controversies as to the proper kinds and amounts of soil tillage required to establish and produce a crop. These controversies have ranged far and wide between farmers, extension service personnel, agricultural specialists, in fact almost every person connected with agriculture has his own unique concept of what constitutes proper tillage. The concepts vary widely from a no tillage program, for certain perennial row crops, to the extreme dust mulch program.

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

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).
