Partial Purification Of Heat Stable Enterotoxin Produced By Escherichia Coli Isolated From A Case Of Porcine Colibacillosis, Lee Ann Zochert Swanson
Electronic Theses and Dissertations
Colibacillosis (CB) in livestock is an economically important disease caused by the bacterium Escherichia coli. It is estimated that nearly one third of all baby pigs born in South Dakota die prior to weaning, and one fourth of these deaths is believed to be caused by CB (62). Similarly, it has been stated that 6 to 20% of calves born alive die from this disease (3). The term colibacillosis encompasses a group of diseases caused by E. coli in neonatal and weaned animals and humans (3). The several different types of CB are due to the differences in tissue localization …

Jean Thomas' American Folk Song Festival : British Balladry In Eastern Kentucky., Marshall A. Portnoy
Jean Thomas' American Folk Song Festival : British Balladry In Eastern Kentucky., Marshall A. Portnoy
Electronic Theses and Dissertations
Serious musicological research initiated in the first decades of the twentieth century in America uncovered vast riches of British folk music that had been transplanted to these shores by early pioneers. In the mountains of Appalachia, traditional British ballads remained miraculously unspoiled, and distinguished researchers from Britain and America published many volumes of such songs. Jean Thomas, a legal stenographer born in eastern Kentucky in 1881, became fascinated with this phenomenon. She came to believe that an annual festival of mountain music would help ensure the survival of this art and, in 1930, she founded the American Folk Song Festival. …

Primary Productivity In Lake Cochrane, South Dakota, During And After Sediment-Control Dam Construction, Randall Francis Brich
Primary Productivity In Lake Cochrane, South Dakota, During And After Sediment-Control Dam Construction, Randall Francis Brich
Electronic Theses and Dissertations
Lake Cochrane was selected for this study because of its history of superior water transparency (Haertel 1972, 1976b). Significant amounts of silt and chemicals enter the lake with runoff at 3 locations (Haertel unpublished data). Restriction or impediment of runoff at these locations should result in improved water transparency (Haertel 1976b, Siegel 1975). Therefore, East Dakota Conservancy Sub-District and the South Dakota Department of Wildlife, Parks, and Forestry decided to impede runoff waters by means of 3 sediment-control dams incorporated into the perimeter road system of the lake and financed through a grant from the Environmental Protection Agency (Siegel 1975) …
Pregnancy Diagnosis In The Ewe, Michael J. Trapp
Pregnancy Diagnosis In The Ewe, Michael J. Trapp
Electronic Theses and Dissertations
The ability to diagnose pregnancy accurately, rapidly and economically before the last six weeks of gestation in the ewe could be of real value as a sheep management tool. An efficient non-surgical pregnancy test could enable the producer to reduce feed costs, increase percent lamb crop and select for fertility. It is important to the health of the ewe and to the survival of the lamb that highly productive animals should be adequately fed. About 75% of the fetus' growth occurs during the last trimester of pregnancy. Therefore undernutrition of the ewe during this part of pregnancy leads to the …
