Characteristics And Distribution Of Staphylococci And Micrococci Isolated From Bovine Udders, Clyde Arnold Kirkbride
Characteristics And Distribution Of Staphylococci And Micrococci Isolated From Bovine Udders, Clyde Arnold Kirkbride
Electronic Theses and Dissertations
Mastitis remains the most costly disease of dairy cattle. The annual loss to the dairy industry in the United States from this disease has been estimated between $225 and $500 million per year. Ninety to 95% of infectious mastitis is reported to be associated with Streptococcus agalactiae or Staphylococcus spp. Staphylococcus aureus and others of the family Micrococcaceae are reported to be the second most commonly found udder pathogens. The pathogenesis of staphylococcic mastitis remains poorly understood. Some research data have indicated that the disease is essentially contagious, and that the source of the organism is an infected udder, and …

Signal Attenuation In V.H.F. Biotelemetry, John Schmelzer
Signal Attenuation In V.H.F. Biotelemetry, John Schmelzer
Electronic Theses and Dissertations
In this paper, the change in loop resistance is examined when the loop is placed at the center of a spherical air cavity which is in turn surrounded by a sphere of physiological saline solution, as shown. The functional dependence of the magnitude of the dissipation resistance on the cavity radius will be studied. The validity of introducing a dissipation resistance will be experimentally tested by immersing a loop in a physiological saline solution and directly measuring the change in resistance with an r.f. bridge. Once the increase in resistance is established, the resultant reduction in radiated power will be …

Studies On In Vitro Boar Semen Storage, Wayne L. Singleton
Electronic Theses and Dissertations
Experiments were conducted in a study of in vitro boar semen storage. Yorkshire boars and Yorkshire-Hampshire crossbred gilts were used and were fed a 16.0% crude protein ration. The sperm-rich fraction of all ejaculates was collected by the gloved-hand technique at a minimum of 48-hr intervals. One experiment involved separating the seminal plasma from the spermatozoa cells within 30min after ejaculation by centrifugation (550 g for 7min) followed by two washings with a glucose-bicarbonate solution. The cells were resuspended in a glucose-bicarbonate solution. The cells were resuspended in a glucose-bicarbonate solution and in glucose-bicarbonate solution plus 20% egg yolk. Percent …

A Rhetorical Criticism Of The Defense In The People V. Sirhan Bishara Sirhan, Suzanne Kiesby
Electronic Theses and Dissertations
Within the present decade, the American public has been shocked by the political assassinations of three well known public figures. One of these was Robert F. Kennedy who was assassinated during a victory celebration at the end of the California primary in 1968.The alleged assassin, Sirhan Bishara Sirhan, a Jordinian immigrant to the United States, pleaded that he committed the murder out of love for Jordan and a loss of faith in Robert F. Kennedy. The public was made aware of Sirhan’s trial through the mass media. The coverage of the trial was somewhat restricted because of laws forbidding any …

Soluble Proteins And Lipoproteins Of Legumes In Relation To Bloat, Loren M. Rommann
Electronic Theses and Dissertations
Percent Fraction 1 protein, total soluble protein, and the lipoproteins of birdsfoot trefoil, white clover, and four varieties of alfalfa (Teton, travois, vernal, ladak) were investigated in relation to ruminant bloat using polyacrylamide gel electrophoresis. The plants were grown in a growth chamber under two daylengths and harvested at the bloom, bud and prebud stages of growth. No statistical difference in percent fraction 1 protein, measured as a percentage of the total soluble protein, could be detected among birdsfoot trefoil and three varieties of alfalfa. Both birdsfoot trefoil and teton alfalfa were significantly lower in percent Fraction 1 protein than …

Electronic Theses and Dissertations
Gout is one of the earliest disease entities to be described in medical writings. Hippocrates noted familial distribution patterns and described its classic symptomatology in the 5th century B.C. Empirical treatment employing colchicine was advocated by Alexander of Tralles in the 5th century A.D. A better understanding of the complex association between clinical manifestations of gout and uric acid, carbohydrate and lipid metabolism has made rational treatment possible only very recently. Ample experimental and clinical data now available show a definite association between disorders of purine metabolism resulting in hyperuricemia and frequent concomitant hyperlipidemia. A high incidence of both …
Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Electronic Theses and Dissertations
Ochratoxin is a toxin produced by fungus Aspergillus ochraceus Wilh. This is one of the poisonous metabolites, like aflatoxin, which when ingested by livestock, poultry, and human beings could produce toxigenic effects—so-called mycotoxicoses. The fungus A. ochraceus is widely distributed in nature and often found in soil and vegetation. Scientists, while searching for causative agents of certain diseases not of bacterial, viral, or nutritional origin, conducted a series of experiments a few decades ago using different species of fungi grown on food and feedstuffs. Toxic effects concurrent with antimicrobial activity of certain species of molds created problems in separating one …
Infiltration Lagoons As A Tertiary Treatment Device, Terry L. Druyvestein
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 …
Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Electronic Theses and Dissertations
When man's view of himself as a being in his universe changes with the tide of events, literary conventions change as well. There is very little in contemporary life that would contradict the assumption that man's view of himself and of his world is no longer governed by the assurance of reason or the confidence of prediction. When certainty of man's place in the universe was commonly accepted, for instance in the eighteenth-century, this assurance was reflected in a literature which was essentially rational and ordered. In the last two centuries, drastic upheavals in the course of human events have …

Erosion Protection For The Outlets Of Small And Medium Culverts, Robert A. Hipschman
Electronic Theses and Dissertations
The development of modern roadways has been regarded as one of the most outstanding accomplishments of the past generation. It has created a society of greater mobility than any of its ancestors. The massive stretches of freeways, expressways, and turnpikes are omnipresent, testifying to a modernization of man that was inconceivable fifty years ago. The design of such trafficways was of no mere coincidence. Millions of dollars and man-hours have been expended on the creation of this vast transportation complex. Continual improvements and new ideas have evolved the highway from rugged wagon trails to its present place of eminence. Included …

The new plant will consist of aeration to remove iron and manganese, lime and alum treatment to partially soften …
Isolation An Characterization Of The Virus Of Epizootic Hemorrhagic Disease (Ehd) Of Deer, Hsing Kuei Liu
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 Origin And Development Of Sunday Competition Between The Hartford Courant And The Hartford Times, James M. Neal Jr.
The Origin And Development Of Sunday Competition Between The Hartford Courant And The Hartford Times, James M. Neal Jr.
Electronic Theses and Dissertations
Despite the fact that the Times was an afternoon paper and the Courant a morning paper, the two were more alike than they were different throughout the 1950s and 1960s. Each newspaper was increasingly influenced by persons not native to New England, but both retained executives with New England roots. They were closely balanced in manpower, they competed vigorously for the same kinds of news, and (after September, 1968) they presented similar Sunday packages. Carl Lindstrom's charge that newspapers were increasingly dominated by the business offices could hardly be applied fairly to either newspaper in Hartford by 1970. The publishers …
A History Of Speech Education At Watertown Senior High School, Watertown, South Dakota, Richard James Reddy
A History Of Speech Education At Watertown Senior High School, Watertown, South Dakota, Richard James Reddy
Electronic Theses and Dissertations
A historical thesis on the development of speech education at Watertown Senior High School, Watertown, South Dakota, is proposed. The specific purpose is to present, in an orderly fashion, a chronology of the development of curricular and cocurricular speech education from the opening of Watertown Senior High School in 1879 through the 1968-1969 academic school year. A study of the past is often valuable as a guide to the future. Historians from the field of speech recognized this fact when, in 1941, they authorized the compilation of A History of Speech Education in America. Chapters 20 and 21 of that …
Factors Influencing Asexual Spore Formation By Ceratocystis Ulmi, Richard J. Roster
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. …
Methods For Rapid Identification And Enumeration Of Streptococcus Bovis From Water, Lawrence Robert Koupal
Methods For Rapid Identification And Enumeration Of Streptococcus Bovis From Water, Lawrence Robert Koupal
Electronic Theses and Dissertations
Because water can be a carrier of enteric pathogenic microorganisms, water pollution from a fecal source is a serious problem to a community obtaining water from streams and rivers. Adequate methods for detection of the enteric pathogens are lacking, consequently, much attention has been given to the detection of other microorganisms as indicators of fecal pollution. The microorganisms called the fecal streptococci are those streptococci which are commonly found in the intestinal tract of man and animals. The fecal streptococci have been divided into two basic groups within the Lancefield Group D streptococci. These two groups are the enterococcus group …
