Power Determination For Mobile Mining Equipment., Gene Thomas Lineberry
Power Determination For Mobile Mining Equipment., Gene Thomas Lineberry
Graduate Theses, Dissertations, and Problem Reports (ETD)
A piece of mobile mining equipment must possess sufficient power to overcome normal resistances and also resistances whose prediction and quantification is much more difficult, such as those accompanying cyclic maneuvers and emergencies. These abnormal, highly variable resistances require a quantity of reserve power. The sum of reserve power, required power, auxiliary power, and ambient corrections represents the total power requirement. Reserve power is traditionally defined as "the additional power available to a vehicle for climbing grades and for acceleration." In this study, reserve power was redefined as "the power available to a vehicle in addition to that necessary to …

Electromagnetic Geophysical Tomography Incorporating Refraction And Reflection., Roger Dale Radcliff
Graduate Theses, Dissertations, and Problem Reports (ETD)
An accurate technique for remotely determining the internal structure of an object or underground environment would have a significant impact in mining, geoexploration, and the life sciences. This process of resolving the intrinsic properties of an object or environment by the transmission of X-rays or electromagnetic waves through the unknown anomaly is known as reconstructive imaging or tomography. Several efforts have been made to apply tomographical methods to electromagnetic measurements taken between two boreholes on either side of an unknown geophysical structure. However, it became necessary, because of the nature of existing reconstruction methods, to assume a straight-line propagation path …

A History Of Game Preservation In British East Africa, 1895-1963., Thomas Paul Ofcansky
Graduate Theses, Dissertations, and Problem Reports (ETD)
East Africa's wildlife is justly famous. This study examines the difficulty of preserving large numbers of wild animals in societies committed to widespread and rapid economic development. In Kenya the colonial administration had to devise a policy that would enable a rapidly expanding European settler community to live side by side with hundreds of thousands of potentially destructive wild animals. As far as Uganda was concerned, the authorities had to prevent the country's elephant herds from destroying agricultural crops without destroying them. Tanganyika's situation was even more complex. A large number of European and African farmers believed that the only …

The Rebec: An Orthographic And Iconographic Study. (Volumes I And Ii)., Margaret Anne Downie
Graduate Theses, Dissertations, and Problem Reports (ETD)
Most musical instruments of Western European culture have been studied and defined; however, no systematic study has yet been made for the instrument commonly known as the rebec (or rebeck). General reference sources and musicological studies which mention the rebec often provide discrepant, vague, and erroneous information. The current interest in the performance of Medieval and Renaissance music and the reproduction of instruments upon which this music might have been played has created a need, among performers and instrument makers, for specific, primary source information concerning the rebec. The use of the rebec in Western Europe can be documented through …

The Antioxidant Effects Of Non-Steroidal Anti-Inflammatory Drugs And Ketamine Against Polymorphonuclear Myeloperoxidase Dependent Bactericidal Mechanisms As Measured By Luminol-Enhanced Chemiluminescence., Gary Michael Pekoe
Graduate Theses, Dissertations, and Problem Reports (ETD)
The interaction of myeloperoxidase (MPO) with H(,2)O(,2) and Cl('-) provides a potent cytotoxic/antimicrobial system for polymorphonuclear leukocytes (PMNs). MPO-related cytotoxicity may be associated with the formation of toxic oxidant MPO intermediates, OCl('-), or both. MPO itself is able to oxidize drugs and cellular components. Non-steroidal anti-inflammatory drugs (NSAIDs) able to act as antioxidant free radical scavengers are shown in this study to inhibit luminol-enhanced chemiluminescence (CL) which results from the MPO-H(,2)O(,2)-Cl('-) interaction. CL is a measure of the production of oxygen-centered free radicals by this reaction. The source of CL which these NSAIDs affect is not OCl('-), once thought to …

Clinical Treatments Of Depression., Deborah Kay Orth
Clinical Treatments Of Depression., Deborah Kay Orth
Graduate Theses, Dissertations, and Problem Reports (ETD)
Depression seems to be a major problem for college students who are coping with academic and social pressures, as well as defining goals for life and career, often without adequate support systems. Therapy is frequently sought by moderately depressed college students. This treatment teaches the individual a style of thinking or a way of approaching their difficulties, but in one study, the 42 percent who did seek therapy rated the effectiveness as only 3.5 on a 5-point scale (Bosse, 1975). Students perhaps also need a means of coping that they can rely on in addition to the insight and behavior …
Talking To A Whirlwind: The Loyalist Printers In America, 1763-1783, George Edward Cullen
Talking To A Whirlwind: The Loyalist Printers In America, 1763-1783, George Edward Cullen
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation tells the story of the Loyalist printers of Revolutionary America. They numbered 34, varying in degree from those who adhered to the crown as a matter of principle, to those who merely wanted to be on the winning side, and still others whose loyalism was due to circumstances of time and place. No attempt has been made to provide a blanket "why" for the actions of the Loyalist printers; each is treated as the individual he was and the reasons for his actions are examined on that basis.

A Free-Vortex Model With Numerical Solution For The Unsteady Lifting Characteristics Of Straight Bladed Darrieus Wind Turbines., Paul Gerald Migliore
Graduate Theses, Dissertations, and Problem Reports (ETD)
A method has been developed to analyze the flow and predict the lifting characteristics of vertical axis wind turbines. Blades are modelled by a number of discrete bound vortices located on the airfoil mean camber line; the wake is modelled by a number of discrete vortices shed from the blade trailing edge. Application of the flow tangency boundary condition and the Kutta condition permit a numerical solution for the strengths of the bound vortices. Blade forces are then determined from potential theory. This vortex model faithfully reflects the important phenomena of flow unsteadiness and wake/blade interaction. Wake details and energy …

A History Of The Samia Location In Western Kenya, 1890-1930., Jacob Raymond Seitz
Graduate Theses, Dissertations, and Problem Reports (ETD)
This is a study of development and change on the local level in East Africa during the introduction and establishment of colonialism. Over the years the emphasis in African History has gradually shifted from the study of imperial policy and the Europeans' role to that of the African inhabitants. Until recently, this new focus has resulted principally in valuable studies of the precolonial life and migrations. Now it is the first decades of the twentieth century that are under scrutiny. This period, spanning the establishment of the colonial system, undoubtably had a great impact on independent Kenya.
