Investigation Of Normalized Streamflow In West Central Florida And Extrapolation To Ungaged Coastal Fringe Tributaries, Kim Beth Clayback

USF Tampa Graduate Theses and Dissertations

Deriving accurate streamflow estimates for ungaged watersheds provides a challenging task for water resource engineers. Traditional methods include correlation to the nearest USGS streamflow station or numeric simulation of watershed rainfall-runoff processes. Mean annual flow, ten percent exceedance and other streamflow indices can be normalized and non-dimensionalized by dividing by the watershed drainage area and the mean annual precipitation rate. Obtaining non-dimensional parameters can be especially useful for extrapolation of flows to downstream, ungaged, coastal fringe regions. Florida and other states along the Gulf Coast exhibit strong variability in the magnitude of streamflow fraction of precipitation. The irregular patterns created …

The Commodification Of Yoga In Contemporary U.S. Culture, Michelle E. Demeter Jan 2006

The Commodification Of Yoga In Contemporary U.S. Culture, Michelle E. Demeter

USF Tampa Graduate Theses and Dissertations

Yoga is an increasingly visible and versatile commodity in the United States health market. Though its origins stretch to pre-Vedic India and its traditional religious purpose is linked to Hinduism, it is evident that yoga has undergone much change since its transmission to U.S. culture. In its popular, widespread incarnation in the United States, yoga is not usually learned at the feet of a guru, but at exercise centers and gyms. These secular locales of yoga's practice help define the "yoga phenomenon" in contemporary America. This phenomenon has resulted in yoga's wide acceptance and high visibility in American popular culture …

This research intends to fill the void in the literature that utilizes the experiences of students to …


Evaluation Of The Long-Term Effect Of Inorganic Leachate On Geosynthetic Clay Liners, Darwish El-Hajji Jan 2006

Evaluation Of The Long-Term Effect Of Inorganic Leachate On Geosynthetic Clay Liners, Darwish El-Hajji

USF Tampa Graduate Theses and Dissertations

Because of its low permeability and high swelling characteristics, bentonite is used in various hydraulic barrier systems and in the manufacturing of Geosynthetic Clay Liners (GCLs). Exposure to inorganic solutions containing elevated concentrations of electrolyte can significantly increase their permeability. To enhance the bentonite's chemical resistance to inorganic solutions, the manufacturers of GCL materials introduced propriety soluble polymeric compounds as an additive to bentonite. The resulting materials are referred to as polymer-treated, chemically-enhanced, or contaminant-resistant clays, and are arguably resistant to a host of inorganic chemicals. In this study, the response of both regular and polymer treated bentonite clays to …

A Marriage Of Convenience: Batista And The Communists, 1933 – 1944, Charles Clayton Hollenkamp Jan 2006

A Marriage Of Convenience: Batista And The Communists, 1933 – 1944, Charles Clayton Hollenkamp

USF Tampa Graduate Theses and Dissertations

This paper examines the relationship between Fulgencio Batista and the Communist Party of Cuba. At odds during the first several years of Batista's rule, when strikes and repression were the topics of the day, the two sides eventually saw in each other a means to an end. In efforts to understand the Cuban Revolution of the late 1950's, historians often portray Batista as a dictatorial puppet of American business and policy. Contrary to this image, in his first regime (1934 until 1944), Batista presided over the creation of a nominal constitutional democracy. To do this he needed the support and …
