Torsors, herds and flocks

This paper presents non-commutative and structural notions of torsor. The two are related by the machinery of Tannaka-Krein duality

Methods of Accelerating the Removal of Moisture from Duckweed and their effect on the Crude Protein Content

The two major objectives were to investigate methods for drying duckweed and to determine the effect of the methods on the crude protein content of the plant. The drying methods were oven drying, sun drying, pressing with heat, pressing without heat, pressing combined with oven drying, parboiling combined with oven drying and drying in a spouted bed. A series of drying curves were developed for each drying method. Due to the high moisture content of duckweed (92.9 to 94.0% wet basis), the drying curves exhibited a long constant rate drying period as opposed to grain crops and hay. Equations were developed for each set of curves in the form F = 1-bT Where: F = fraction of water remaining in the sample T = drying time in hours b = drying coefficient In the oven drying, the duckweed was exposed to temperatures of 80, 100, 120 and 140°C. At 120°C and above, the samples exhibited a burned appearance. The samples dried in the sun generally took 11/2 times to 3 times as long to dry as in the oven with the same depth. Parboiling prior to oven drying increased the initial moisture by 0.9% but reduced the drying time. Samples were pressed at 60, 125 and 250 psi and then oven dried. These samples took less time to dry than oven dried samples at the same depth. The samples pressed at higher pressures turned darker green as the pressure was increased. Duckweed was also dried in a spouted bed apparatus at 27 and 50°C. This method took less time to dry the duckweed than any other drying method investigated in this study. The crude protein content of the samples was determined by a standard Kjeldahl analysis. A statistical analysis was then made on the results. Two analyses of variance were made: (1) to compare the oven dried samples to the untreated samples and (2) to compare all other methods to one another. In the second analysis the samples pressed at 780 to 7,810 psi were not included since it was obvious from visual observation that the crude protein contents were significantly decreased by pressing. Pressing at high pressures reduced the crude protein by 66 to 71%

Martin Luther King\u27s Selma To Montgomery March Of 1965 As Reflected In Selected National Media

The significance of this study lies in the examination of the effect of the media upon the public image of an historical event. Such a test was projected from the standpoint of the full range of media, viz., newspapers, magazines, radio, and television. This investigation will demonstrate that the media is furnishing for the future historical documents, and that this kind of documentation has to be understood in all of its dimensions, i.e., idealogy, frame of reference, clientele, climate of opinion, etc., if the historian is to make the best use of the information provided. The test incident is the Selma March of 1965 led by Dr. Martin Luther King, Jr. This study will reveal the flavor and nature of the media documentation of this event which occurred March 21 through 25, 1965. The span of the media will give the writer the opportunity to compare image-making techniques and assess the probable impact upon future understanding of the event. Statement of the problem. What is the effect of the nature of the media upon their validity as sources of historical documentation? Some scholars have a feeling of skepticism toward the validity of the media for purposes of historical documentation. Professor Hockett states that the historian who uses newspapers as sources must take pains to check all statements with care. Newspapers include matters of many different kinds, and the critic\u27s attitude must vary according to the nature of the item. Weekly and monthly news journals, he believed, are more trustworthy than the dailies

Transatlantic Latter-day Saints: Mormon circulations between America and South Africa

Includes bibliographical references."Transatlantic Latter-days Saints" is an analysis of Mormonism in South Africa from a history of religions perspective. Contextualizing the Mormon experience in South Africa, the central concern of this dissertation is whether or not the religion's history in the country should be defined as distinctly American. By tracking historical transatlantic circulations, mapping changing territories, and utilizing the comparative strategies of scholars such as Jonathan Z. Smith and David Chidester, this study documents and analyses the changing associations of South African Mormonism with America. In some instances, such as its nineteenth-century practice of polygamy and its twentieth century policies of racial prejudice, Mormonism appears to be more at home in South Africa than in America. In other areas, such as the contributions made by Mormon missionaries during the 1930s in the organization and development of the game of baseball in South Africa, the religion utilized its American heritage to contribute to its advantage as well as to the Americanization of South Africa. While these case studies yield conclusive outcomes, others, such as the historical mapping of the life and legend of Gobo Fango, display the complexity of tracking transatlantic circulations between America and South Africa. This dissertation demonstrates that despite Mormonism's location on the periphery of South Africa and South Africa's peripheral position within Mormonism, the transatlantic circulations that link America, Mormonism, and South Africa raise issues that are often of central concern to both countries and to the religion. By attending to Mormon circulations between America and South Africa, this dissertation develops alternative perspectives on such important areas of study as nineteenthcentury missions, slavery, policies of racial discrimination, and American popular culture
