An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue Jan 1983

An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue

Electronic Theses and Dissertations

Cow and calf losses due to pine needle abortion in cattle grazing foothill ranges of ponderosa pine (Pinus ponderosa) continue to cause managerial and economic problems for ranchers in South Dakota, Colorado, Idaho, California, Montana and many areas throughout Canada. Because of its overall economic significance, investigators have been attempting to isolate and characterize causative agents of pine needle abortion. To date, a large number of pine needle constituents have been shown to possess abortifacient capabilities. In addition to actual pine needles, it appears that several other undefined factors may be associated with, and (or) predispose animals to, pine needle …

The Development Of Palestinian Territoriality, Jan Charles Betholf Jan 1983

The Development Of Palestinian Territoriality, Jan Charles Betholf

Electronic Theses and Dissertations

The land of Palestine has been the object of conflicting claims by numerous peoples and religions for millennia. This small, arid place generally consisting of territory east and west of the Jordan River has been ruled and coveted by Jews, Christians, and Muslims. Each now possesses historical, cultural, and religious attachments to the land. The Jewish claim to Palestine rests on their conquest of the "promised land" in 1451 B. C. E. and their 1500-year occupancy which ended with the Diaspora in 71 A. D. Christian occupation during the crusades and the importance of the land that Jesus walked also …


Health Knowledge Assessment Of College Freshmen Educated In South Dakota K-12, Nadeen E. Lunde Jan 1983

Health Knowledge Assessment Of College Freshmen Educated In South Dakota K-12, Nadeen E. Lunde

Electronic Theses and Dissertations

Nothing in life is so taken for granted when possessed, or so missed when lost, as is health. Therefore, it is essential to possess basic facts if each individual is to take advantage of medical science advances, protect himself against quackery, and obtain an optimum level of health. Health education is recognized by leading educators as of vital importance in educating our youth, but health education has not established itself in a way comparable to other subjects. Kilander noted this fact as early as 1937, and yet, 46 years later, South Dakota's health education programs have not been established. Many …


Vitamin A And Carotene Supplementation On Feedlot Lambs, Donald F. Samuel Jan 1983

Vitamin A And Carotene Supplementation On Feedlot Lambs, Donald F. Samuel

Electronic Theses and Dissertations

After the discovery and identification of vitamin A as an essential nutrient, the role of the vitamin and its precursor carotene in the nutrition of animals came under widespread study. Many experiments have been designed in the past to examine the interrelationships concerning vitamin A and carotene in animal feeding. In view of the similarity of digestive systems between cattle and sheep, it was reasonable to assume that vitamin A and carotene might function much the same in the two species. As numerous investigators have demonstrated, there are many similarities in vitamin A metabolism between cattle and sheep. However, there …


Pilot Plant Production Of Cellulase By Trichoderma Reesei Qm9414 And The Effect Of Dimethyl Sulfoxide On Cellulase Production By T. Reesei Mcg77, Paul J. Whalen Jan 1983

Pilot Plant Production Of Cellulase By Trichoderma Reesei Qm9414 And The Effect Of Dimethyl Sulfoxide On Cellulase Production By T. Reesei Mcg77, Paul J. Whalen

Electronic Theses and Dissertations

Approximately 15-20 x 1010 tons of organic plant substance is produced on earth per annum. Half of this material is cellulose. Much of this cellulosic material is highly resistant to breakdown due to other plant components such as lignin and hemicellulose which together with the cellulose contribute to the structural integrity of the plants. Thus, these materials find relatively limited uses in comparison to their abundance. Cellulosic materials are utilized by ruminants as an energy source and in lumber and pulping applications but commercial cellulose processing to produce glucose or glucose derived products is not currently performed. The abundance of …

Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar Jan 1983

Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar

Electronic Theses and Dissertations

Cottage cheese has the largest sales volume potential of all cultured dairy products in the United States today. Moreover, it can be a highly profitable product if proper control is exercised during its manufacturing (46). Commercial production of cottage cheese utilizes a significant portion of the total fluid milk produced in the U. S.A. After the 1955's, yearly per capita consumption of cottage cheese increased from 1. 7 7 kg (3.9 lb) to a high of 2. 45 kg (5.4 lb) in 1972 (67) . Consumer demand for lower fat dairy products gradually increased, which put more pricing emphasis on …

Neutron Activation Analysis For Trace Metal Content Of Brookings Sludge For Land Application, Daniel George Dewall Jan 1983

Neutron Activation Analysis For Trace Metal Content Of Brookings Sludge For Land Application, Daniel George Dewall

Electronic Theses and Dissertations

The Federal Environmental Protection Agency (EPA) strongly favors land application of sludge as a disposal method and requires communities to consider the application of sewage wastes to land as one of their alternatives to advanced wastewater treatment in order to be eligible for federal funding to improve sewage wastewater treatment facilities. Although use of sewage sludge on the land has definite benefits, several potential problems may develop when applying this method of disposal. One main concern has been the possibility of toxic metal pollution occurring in the application soils. If high concentrations of zinc, copper, lead, cadmium, etc. are present …


Determination Of Body Density Of College-Age Women Using Circumference Measurements, Melinda J. Robins Jan 1983

Determination Of Body Density Of College-Age Women Using Circumference Measurements, Melinda J. Robins

Electronic Theses and Dissertations

The purpose of this investigation was to determine an effective and simple method of estimating body density of college-age women (n=51), ages 18 to 26 years, using age and selected circumference measurements (thorax, waist, abdomen, hip, gluteal fold and thigh). Two subproblems were also investigated. The first subproblem was to determine if the sum of the selected circumferences was a better predictor of body density than when each circumference was used individually as a predictor. The second subproblem was to determine if body density could best be predicted by a linear or curvilinear relationship. Statistical analysis of the data included …
