Infiltration Lagoons As A Tertiary Treatment Device, Terry L. Druyvestein Jan 1970

Infiltration Lagoons As A Tertiary Treatment Device, Terry L. Druyvestein

Electronic Theses and Dissertations

As the United States continues to grow and expand industrially, increased mechanization and shorter work weeks will result in a populace which will expect to enjoy increasing amounts of leisure time. Part of this leisure time will be used to participate in outdoor recreation activities, the result being an increased demand on lakes and streams. Maintaining these waters in a suitable condition for recreation and other beneficial uses has become the concern of most Americans. The Water Quality Act of 1965 and the subsequent state water quality standards are ample proof of the concern given to the control of water …


A Chromosome Study Of Chlorophytum Elatum, Dennis E. Driscoll Jan 1970

A Chromosome Study Of Chlorophytum Elatum, Dennis E. Driscoll

Electronic Theses and Dissertations

The spider plant, Chlorophytum elatum R. Br., a member of the family Liliaceae, is a native of South Africa. It has been propagated almost exclusively by vegetative means and it is now grown widely over the world as an ornamental plant. Many studies by other workers have revealed that with only two exceptions all species in the genus Chlorophytum have somatic chromosome numbers that are multiples of seven, ranging from 14 to 56 (c.f. Darlington and Wiley, 1955). Although the chromosome number of Chlorophytum elatum has ·been reported to be 2N = 28 (Sato, 1942; Baldwin and Speese, 1951) information …


Supplementation With Vitamins A And D Of Beef Cattle Finishing Rations Containing Various Levels Of Carotene From Corn Silage And Corn Grain, Harold Richard King Jan 1970

Supplementation With Vitamins A And D Of Beef Cattle Finishing Rations Containing Various Levels Of Carotene From Corn Silage And Corn Grain, Harold Richard King

Electronic Theses and Dissertations

The purpose of this experiment was to determine the need for vitamin A and vitamin D supplements with rations composed of various levels or corn silage and corn grain when fed to cattle. Early investigations with vitamin D demonstrated that the reduced intensity or sunlight during the winter months resulted in decreased cutaneous formation of vitamin D and that dark- skinned animals synthesized less vitamin D than light skinned animals under given conditions of light intensity. Thus this experiment was conducted with Angus and Angus x Hereford crossbred steers and, to the extent possible under seasonal conditions considered to be …


Relationships Of Homologous Erythropoietin, L-Ascorbic Acid, And Iron Dextran To The Hemogram Of Newborn And Doe Rabbits, Lloud Edward Lippert Jan 1970

Relationships Of Homologous Erythropoietin, L-Ascorbic Acid, And Iron Dextran To The Hemogram Of Newborn And Doe Rabbits, Lloud Edward Lippert

Electronic Theses and Dissertations

The neonatal-anemia syndrome, an anemia of newborn animals, in a commonly observed physiological phenomenon in swine, humans and rats. The severity of the anemia is subject to unpredictable individual variation, but may be modified by the nutrition of the dam. Alterations in swine neonatal hemogram values begin 3-5 days postpartum and include decreases in packed cell volume and hemoglobin concentration. Vigorous and healthy appearing newborn become weak and particularly subject to infective agents and stresses, which may terminate in death. A slow return to postpartum hemogram values is observed if the newborn animal survives. The economic considerations of newborn mortality …


Isolation An Characterization Of The Virus Of Epizootic Hemorrhagic Disease (Ehd) Of Deer, Hsing Kuei Liu Jan 1970

Isolation An Characterization Of The Virus Of Epizootic Hemorrhagic Disease (Ehd) Of Deer, Hsing Kuei Liu

Electronic Theses and Dissertations

The name "epizootic hemorrhagic disease" (EHD) of deer was first given by Shope et al. in 1955 because of the occurrence of the hemorrhagic disease in large epizootic_ proportions and because of its pathological features. It was also determined by them that the causative agent for the disease is a virus. Difficulties in studying the causative agent have been encountered because no host system other than the deer itself was available to support replication or detect the virus. However, isolation of the New Jersey strain of EHD virus was accomplished by Mettler et al. in 1962 using newborn mice and …


The Effects Of 2-Chloroethylphosphonic Acid On Bud The Effects Of 2-Chloroethylphosphonic Acid On Bud Vascularization In Sorghum Halapense, L.Ascularization In Sorghum Halapense, L., Robert Allen Peterson Jan 1970

The Effects Of 2-Chloroethylphosphonic Acid On Bud The Effects Of 2-Chloroethylphosphonic Acid On Bud Vascularization In Sorghum Halapense, L.Ascularization In Sorghum Halapense, L., Robert Allen Peterson

Electronic Theses and Dissertations

An assumption can be postulated that the auxin produced in the stem apex may inhibit bud development by preventing differentiation of vascular connections between the cauline bundle and the bud primordia. This would deprive the primordia of nutrients and growth substances being translocated in the mainstream vascular elements. The assumption is that prior to decapitation, vascularization is incomplete to the laterals in johnsongrass and that after decapitation, vascularization becomes complete. Dr. C. A. Beasley has found that plants treated with ethrel will react the same as decapitated plants. This study was designed to examine ethrel treated plants and examine anatomically …


Factors Influencing Asexual Spore Formation By Ceratocystis Ulmi, Richard J. Roster Jan 1970

Factors Influencing Asexual Spore Formation By Ceratocystis Ulmi, Richard J. Roster

Electronic Theses and Dissertations

Stock cultures of a pure strain of C. ulmi were obtained from the Plant Science Department at South Dakota State University. The inoculum was maintained on Potato Dextrose Agar (PDA) in petri dishes. On this medium, the fungus produced a grayish white rather sparse and appressed mycelium. Conidia were produced in heads on branched conidiophores. Quite often some sectoring was observed on PDA. Cultures producing coremia, obtained on 2% American elm shavings (on dry weight basis) plus bacteriological agar (8 g/1), were also used as an inoculum source. As is shown, this medium produced coremia and very little vegetative mycelium. …


Demonstration Of Glutamate Dehydrogenase In Azotobacter Vinelandii, Jack A. Turner Jan 1970

Demonstration Of Glutamate Dehydrogenase In Azotobacter Vinelandii, Jack A. Turner

Electronic Theses and Dissertations

In the early part of this century it was observed that certain microorganisms could grow in the absence of fixed nitrogen. Since those early observations there has been an intensive effort to unravel the mystery behind the physiology of nitrogen fixation. It was not until development of the use of heavy isotopes that we begin to learn the mechanism of biological nitrogen fixation. It was the object of this study to determine if glutamate dehydrogenase (GDH) was present in A. vinelandii when it was fixing nitrogen. If it is assumed that GDH is the principal means of assimilation of NH+4 …


Root Pulls And Root Ratings As An Analysis Of Insecticide Performance In The Control Of Corn Rootworms (Coleoptera: Chrysomelidae), James I. Jessen Jan 1970

Root Pulls And Root Ratings As An Analysis Of Insecticide Performance In The Control Of Corn Rootworms (Coleoptera: Chrysomelidae), James I. Jessen

Electronic Theses and Dissertations

The western corn rootworm, Diabrotica virgifera Leconte, the northern corn rootworm, Diabrotica longicornis (Say), and the southern corn rootworm, Diabrotica undecimpunctata howardi Barber, are major pests of corn in the corn belt region. In South Dakota, the western and northern corn rootworms are the two predominant species that produce economic damage. The damage produced by this insect complex has elevated them to the position of the number one corn insect pest. In South Dakota the corn rootworm was estimated to produce 5o% of all damage that occurs to corn (Jones, 1968). The corn rootworm is an important factor in the …


The Identification Of Changing Sex Roles Within A Family Unit As Perceived By First Graders, Janelle Fridley Jones Jan 1970

The Identification Of Changing Sex Roles Within A Family Unit As Perceived By First Graders, Janelle Fridley Jones

Electronic Theses and Dissertations

Family life education includes the total education for living in families. The main emphasis of all home economics or homemaking education is life as it is lived within the home and family. Some aspects of home economics are usually included in the curriculum at all age levels from early childhood through secondary education. Family life in America has changed over the years. Such factors as family mobility, a greater amount of leisure time, an increase in early marriages, and more mothers employed outside the home indicate the need for education in family living. Moreover, currently fewer youngsters learn about homemaking …


A Differential Ph Requirement For Extraction Of Stable Polyribosomes From Winter Barley In Relation To Rnase Activity Of The Tissue, Clay G. Johnson Jan 1970

A Differential Ph Requirement For Extraction Of Stable Polyribosomes From Winter Barley In Relation To Rnase Activity Of The Tissue, Clay G. Johnson

Electronic Theses and Dissertations

The development of a systematic procedure to fractionate cells into functional components is important to many current problems in biological research. Polyribosomes are of considerable interest since it is this cell fraction which is the site of protein synthesis. They are unique structures in that they are reported to contain the transcribed genetic information in the form of messenger RNA (mRNA) which functions as the binding site for ribosomes in the decoding process. A satisfactory isolation of polyribosomes provides an opportunity to analyze the nature of this transcribed genetic message and also determine the extent to which protein synthesis is …


The Influence Of An Unusually High Water Table On Ground Water Quality At A Refuse Disposal Site, Charles Strock Johnson Jan 1970

The Influence Of An Unusually High Water Table On Ground Water Quality At A Refuse Disposal Site, Charles Strock Johnson

Electronic Theses and Dissertations

At a 1961 symposium on ground water contamination and later in 1963 at a national conference on solid wastes, concern was shown for the protection of one of our most valuable resources - ground water. It was felt at both conferences that a definite need existed for more research in areas pertaining to the nature and mobility of chemical and biological contaminants leached from refuse disposal areas. Finally, in 1965, because of the interest shown in these problems, Congress passed the Solid Waste Disposal Act which created the Office of Solid Wastes within the Public Health Service. Included in on …


A Comparison Of A Low Protein Diet Plus Added Methionine With A Normal Diet For Three Strains Of Laying Hens In Various Environments, Roger Dale Muller Jan 1970

A Comparison Of A Low Protein Diet Plus Added Methionine With A Normal Diet For Three Strains Of Laying Hens In Various Environments, Roger Dale Muller

Electronic Theses and Dissertations

The protein requirement of the laying hen encompasses a problem of great importance to the nutritionist. With the discovery of amino acids, which are commonly referred to as "the building blocks of protein," it was soon evident that the fowl had a requirement primarily for amino acids, not protein. It has been difficult to establish the exact amino acid requirements of each species and age group. To overcome this difficulty, feed formulae for laying hens as well as other groups of fowl have been designed to provide a surplus of protein and thus amino acids from a wide variety of …
