Selenoamino Acids In Wheat And High-Selenium Yeast, Jinq Lih Lee. Lee May 1986

Selenoamino Acids In Wheat And High-Selenium Yeast, Jinq Lih Lee. Lee

Electronic Theses and Dissertations

Selenium has been known to cause toxicity problems in animals since 1928. These problems arise when the element occurs in the soil at reasonably high concentration and is taken up by plants. Animals consuming the plants may then develop certain toxicity signs. More recently selenium has been shown to be an essential nutrient because of its involvement in the enzyme glutathione peroxidase (Rotruck et al., 1973). Evidence has been accumulating that the element may even help protect against cancer in humans (Shamberger, 1970). Consequently, there has been great interest in knowing about the content of selenium in various foods and …

Frontier Agriculture, 1880-1910 : An Area Investigation Of Human And Environmental Factors Involved In The Process Of Agricultural Evolution In Davison County, South Dakota, Chak P. Lee

Electronic Theses and Dissertations

Our curiosity about how an area has developed into what it is today invariably draws our attention to its initial situation. In the United States, the frontier serves as the logical locus upon which questions such as the latter can be laid. Frederick Jackson Turner has popularized the frontier concept by elevating its place in the history of the American national development. What Turner's frontier thesis has for special offer to geography lies in the observation of the frontier as a discrete areal unit, set off, as it was, from the settled area due to the differential pace in the …

Effects Of Eptc And Acifluorfen On Sunflower, Mark E. Law

Electronic Theses and Dissertations

Sunflowers (Helianthus annuus L.) rank third in acreage among the world's oil crops. Approximately 185, 000 ha of sunflowers are grown in South Dakota each year. Despite sunflower's economic importance, few herbicides are available for use in the crop and many of the herbicides commonly used on soybeans (Glycine Max (L.) Merr.) and corn (Zea mays L.) will harm sunflowers. Therefore, weed infestations are a major factor confronting the sunflower grower. Wild mustard (Brassica kaber (DC.) Wheeler) and green foxtail (Setaria viridis (L.) Beauv) commonly infest sunflower fields in North and South Dakota. According to a survey in North Dakota, …

Effects Of Gamma Irradiation On Chicken Fats, Myung Chul Kim May 1986

Effects Of Gamma Irradiation On Chicken Fats, Myung Chul Kim

Electronic Theses and Dissertations

Food irradiation is a process which may provide an alternative to existing conventional food processes. It will not completely replace or substitute for other processes, but its unique qualities offer an additional processing option. A major difficulty with food irradiation is that it can potentially affect all food, and thus it touches on all food issues - from affecting the physical characteristics of food to labeling and consumer acceptance. Research directed toward the use of radiation for the preservation of foods began in 1945. Most of the studies have been government sponsored, at least partly because the 1985 food additives …

Effects Of Prostaglandin F2a [Alpha] Dose On Synchronizing Ovine Estrus Using A Single Injection Regimen, Karl F. Hoppe

Electronic Theses and Dissertations

The cyclic nature of the reproductive process for females has elicited the focus of reproductive specialists. Alterations in this cycle may lead to a more productive female and consequently a more productive livestock operation. These alterations could entail changing the time of the year conception can occur and the specific times during the week estrus may be displayed. For example, the domestic sheep, Ovis aries, has an estrous cycle length of approximately 17 d, whereas the European beef cow Bos Taurus has an estrous cycle of approximately 21 d. Variations within species lead to ranges for parameters which may place …

Role-Taking And Power In Health Care, Dana Charles De Witt Apr 1986

Role-Taking And Power In Health Care, Dana Charles De Witt

Electronic Theses and Dissertations

This study focuses on differential role-taking ability between physicians and nurses. Many sociologists note, subordinates are in positions of lower structural power than superordinates and therefore must employ other means of control.
