Tests Of A Suggested Piezometric Method For Determining Hydraulic Conductivity Of Saturated Soils, K. R. Channarasappa

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A major factor in the design of drainage systems is the hydraulic conductivity of the soil strata to be drained. Various methods for measuring the hydraulic conductivity of soils in both the field and the laboratory have been devised. In many cases, however, laboratory methods fail to give reliable data since the natural field conditions under which flow actually takes place cannot be duplicated in the laboratory. Hence a need exists for a field method for measuring hydraulic conductivity of soils in situ. When a large number of tests are to be performed in a given location, a simple, quick, …

The Programmed Text As An Aid To Teaching Spelling In Junior High School, Gordon Howard Nicholls

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Organized education, historically, has been slow to commit itself to any sort of intensive examination of how learning can be both analyzed and substantially improved. But today Komoski (1960) tells us that we are looking beyond the traditional approaches to teaching. If a newly developed method is shown to be more effective than the techniques which have traditionally been employed, it is carefully considered for incorporation into the current education program.

Programmed instruction is just such an example of a recently developed teaching method which claims it will contribute much to education. It dates back to Pressey's report (1926) of …

A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.

While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …

Effect Of Calcium Availability On Alfalfa Grown In Calcareous High Sodium Soils, Harry Irving Nightingale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil science we shall always be confronted with reactions in soils that involve Ca. Early recognition of this led to experimentation in this area. Due to the fact that Ca deficiency is most common in acid soils, the majority of the experimentation has in the past been largely confined to acid soils and their soil-Ca-plant relationships. There has been relatively little research done with Ca and its availability problems associated with alkaline or sodic soils.

Basic Problems In Playing The Cornet, Loyal J. West

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

After having spent a number of years in the teaching profession, the writer has become aware of the need for a study dealing with the specific and technical problems in playing the cornet.

The problems of performance on the cornet may readily be divided into three groups: (1) those having to do with the instrument, (2) those having to do with the player, and (3) those having to do with the interpretation of music. The problems of playing the cornet will be dealt with in this paper only as they apply directly to the problems of learning the instrument itself. …

A Critical Analysis Of Water Rights And Institutional Factors And Their Effect On The Development Of Logan River, Frank W. Haws

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The physical setting of the Logan River Drainage Basin is first described with emphasis on the hydrologic and climatic factors that made the river an economic and social benefit.

The historical development of the river by man is then traced, and changes in water use patterns are pointed out. Methods used to administer water rights as water use patterns change is then described.

Legal controversies over water rights on the river are examined and methods of solving problems analyzed. A recent law suit between Logan City Corporation and the Logan River Water Users Association is examined in detail and the …

The Kinetics And Mechanism Of The Reaction Of Molybdenum(V) With Iodine, Oxygen And Nitrate, Ervin Park Guymon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum compounds present a series of baffling chemical puzzles. By no means are all of these yet even clearly defined and many may never be. This complexity results from the ability of molybdenum to form six different oxidation states, which can possess three different coordination numbers. Furthermore, molybdenum compounds readily disproportionate to yield mixed valence compounds; and finally, molybdate ions readily aggregate in solution to form a variety of polyions by polymerization-condensation reactions which are controlled by pH and the concentration of the system. Molybdenum's complexity can best be summed up in the words of the late Edgar Smith who …

A Study Of 5-Fluorouracil: Its Effects And Mode Of Action In Drosophila Melanogaster, John B. Jenkins Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations involving the fluorinated pyrimidine, 5-fluorouracil, and its effects on viruses, bacteria, plants and mammals, have brought to light the following facts: FU inhibits the growth of bacteria, plants and mammalian cells and it decreases the ability of certain viruses to produce progeny. In other words, FU is an antimetabolite that inhibits growth and/or reproduction. Two mechanisms have emerged from these studies to define the mode of action of FU. The first mechanism involves the incorporation of the compound into the RNA of the organism thus altering the base sequence and creating a non functional or damaging nucleic acid. The …

Effect Of Fluoride On Respiratory Enzymes In Soybean Leaves, Arthur Chiu-Eng Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many reports relating the effects of fluorides on plant respiration. Fluoride has been regarded as an inhibitor of respiration. Warburg et al. (1942) demonstrated that fluoride inhibited enolase activity, therefore, decreased the respiration rate of yeast. Miller (1958), found a similar inhibition of enolase from pea seed. Bonner (1948), Bonner and Wildman (1946), and Laties (1949) reported that the fluoride ion in culture solutions reduced the respiration rate in Avena Coleoptile, spinach leaves and barley roots. Since the inhibition was reversed by the addition of pyruvate, they concluded that the inhibition of respiration was due to the inactivation …

Chlorophyll, Cartenoid And Protein Metabolism In Relation To Iron Chlorosis, Antaraguttu Subbayya Shetty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron as an essential element has been known since 1843, when Gris proved its need for the growth and well being of plants. Since then, many investigations have been carried out on various aspects of iron nutrition, leading to the accumulation of a vast literature, a monument to the assiduity of the chemists and the biologists.

Topography Of The Abdominal Nervous System And A Review Of The Abdominal Musculature Of The Honey Bee Apis Mellifera Linnaeus, Nabil N. Yousef

Biology

Studies of insect nervous systems have lagged behind other internal morphological studies for various reasons, the more obvious of which are: the understanding of external morphology remains incomplete; techniques for staining and dissecting nervous tissue have not been fully developed; dissections are time consuming; associations of various nerves between different insect taxa are very difficult; and until the past two decades, the importance of the insect nervous system has been considered insignificant in applied entomology .

The Multiplication Of Lambda And Lambda-Dg Within Their Lysogenic Host Escherichia Coli K12, Gerald D. Elseth

Biology

Bacteriophage λ and its variant λdg, present in the prophage condition within their lysogenic host Escherichia coli K12, can be induced to vegetative multiplication by irradiation with ultraviolet light. Experiments conducted within this laboratory to determine the intra-cellular synthesis of λ and λdg after lytic induction indicate changes in concentration ratios between the two bacteriophages. This change in ratio is dependent upon the growth conditions of the bacteria and the dose of ultraviolet light used for the induction process. Further investigation into this problem is needed and was the major objective of this thesis study.

The Genetics Of Abnormal Head Morphogenesis In Drosophila Melanogaster, With Special Reference To Eyelessness, Homoeosis, Penetrance, Asymmetry, And The "Fourth" Instar, James Wesley Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959) some files from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Edwards and Gardner (1962) designated the stock as eyes-reduced and located the major genetic factor (eyr) in the right arm of the third chromosome. The eyes-reduced stock possesses characteristics which are challenging to current theories in genetics and development; the purpose of this investigation was to thoroughly study those characteristics.

The Influence Of Respiration On The Movement Of Water Through Tomato Root Systems, Ward Bryce Roberson

Biology

The rate at which water moves through the root system of a plant is influenced, in some way, by the metabolic activities of the living cells which compose the tissues of the roots. This conclusion is based on the fact that water movement and metabolic activity are similarly influenced by certain chemical and environmental factors.

Parent Education In A Cooperative Nursery School, Owen William Cahoon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parent education has existed for as long as one parent has attempted to help another, and for as long as we have records. To what extent it has served its purpose has not been fully established. Only the future will fully tell how successful parent education programs have been among those who participated in them, because the final measure of success of a parent education program is the degree to which it contributes to effective family relationships and to favorable growth and development of children in the home.

Parent education sometimes is defined as the use of educational techniques to …

Effect Of Fluoride On The Respiration Of Leaves From Higher Plants, Ming-Ho Yu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies concerning the effects of fluoride on the metabolism of both animals and plants have been of interest to many workers. In plants, it has been known that fluoride will inhibit the growth, that it will induce chlorosis as an evidence of visible injury, and that necrosis will eventually result. The economic importance associated with fluoride damage has been widely recognized, and, as a consequence, fluoride has become a major problem of air pollution.

Temperature Dependence Of Soil-Moisture Potential, Jacob Willem Kijne

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers have noticed that children draw only those objects which they know by name. Doubtless the adult has a similar tendency, exemplified by the researcher, to limit his observations or to relate them to that which can be expressed in the terminology of an existing or newly developed theory. In this thesis the data obtained from studies of the temperature and pressure dependence of the relative vapor pressure over moist soil samples are analyzed by a thermodynamic approach. Not all of the results can be explained completely by means of this tool. Natural systems, such as a moist soil, are …

Influence Of Sodium And Calcium Chlorides In The Nutrient Solution On Secretions Of Salt Glands Of Tamarix Species, Don L. Chadwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt glands are an adaptation for living in saline habitats possessed by several species of plants. In the family of Plumbaginaceae at least three mangrove genera, Aegialitis, Aegiceras, and Avicennia, possess salt glands according to Scholander (1962). Salt glands of the small ornamental shrubs, Statice gmelini, and Limonium latifoluim of the same family, were studied by Ruhland (1915) and Arisz (1955). Spartina townsendii of the Graminaceae and Tamarix petandra, Tamarix hispida, and Tamarix aphylla of the Tamaricaceae families also have the glands.

The Site Of The Immune Reaction Against Eimeria Bovis In Calves And The Demonstration Of Antibodies By Immunofluorescence, Ferron L. Andersen

Biology

In 1959 Senger et al. reported that calves which had received a small oral inoculation of Eimeria bovis oocysts were later resistant to larger challenge inoculations. In an investigation on the mechanism of this immune reaction, Hammond et al. (1959) compared the number and size of E. bovis schizonts in immunized and nonimmunized calves, but found no significant difference in the results. They conducted 3 experiments using 28 young male Holstein-Friesian calves, and killed the majority of these calves for examination 17 to 20 days after the challenge inoculation.

The Effect Of Monosodium Glutamate As A Possible Mutagen On The Compound Eye Of Drosophila Melanogaster, N. Roger Hawkes

Biology

Phenotypes of Drosophila can be altered by subjecting developing larvae to changes in environment. Such environmental changes may be temperature shocks, ionizing and non-ionizing radiation and chemically altered media. Most alterations in phenotype are not inherited, and may resemble the effects produced by known mutant genes. Such alterations are called phenocopies.
