Cost/Effectiveness Analysis Of Obtaining Operational Estimates Of Reference Evapotranspiration, Peninsular Florida, Usa, Michael G. Kittridge

USF Tampa Graduate Theses and Dissertations

The objective of this study is to conduct a cost/effectiveness analysis of the computation of reference evapotranspiration (ETo) in the peninsular of Florida. A meteorological station on the Fort Meade Mine in Polk County, Florida was used to provide data for the calculation of ETo. Five ETo equations were tested to determine the accuracy and cost/effectiveness to the fully measured ASCE Penman-Monteith (Full ASCE-PM) equation on daily, monthly, and annually time steps. The ETo equations ranged in amounts of parameters from the Full ASCE-PM to the Hargreaves. The energy terms accounted for approximately 90% of the total ETo flux. Solar …

Hydrostratigraphy And Groundwater Migration Within Surficial Deposits At The North Lakes Wetland, Hillsborough County, Florida, Jason J. Laroche

USF Tampa Graduate Theses and Dissertations

A wetland in west-central Florida was studied to characterize the local hydrostratigraphic configuration of surficial deposits overlying more-permeable limestones and conceptualize groundwater recharge. Eight continuous cores were drilled through the surficial deposits and partially into the underlying limestone. A total of 111 samples were extracted from the cores for laboratory sediment analyses and testing. The surficial deposits are roughly eight meters thick and made up of upper and lower clean-sand hydrostratigraphic layers (S1 and S3, respectively) separated by a low-permeability layer of clayey sand (S2). Also, a discontinuous low-permeability layer of clayey sand (S4) lies between S3 and the top …

Functionalization Of Resorcinarenes And Study Of Antimicrobial Activity, Kirankirti Muppalla

USF Tampa Graduate Theses and Dissertations

Cavitands are very important class of compounds in supramolecular chemistry. These molecules contain rigid enforced cavity,and have attracted considerable attention in supramolecular chemistry as building blocks for the construction of carcerands, hemicarcerands, and other host guests complexes. Nearly 40 years ago, Niederl and Vogel laid foundation for the study of such type of condensation reactions. In our laboratory we are involved in synthesis of resorcinarenes with readily available substrates such as resorcinol and aldehydes to form a cyclic tetramer.

Herein, I present detailed studies about the functionalization of the synthesized tetramers and their antimicrobial activity. Octahydroxy resorcinarenes were synthesized and …

Climatic And Structural Controls On The Geomorphology Of Wadi Sana, Highland Southern Yemen, Joshua Michael Anderson

USF Tampa Graduate Theses and Dissertations

Middle Holocene climate change forced significant environmental response and influenced human activities throughout southern Arabia. Climate models and proxy data indicate that climate along the southern Arabian peninsula changed from a moist phase, spanning the early to middle Holocene, to an arid phase, which persisted for the last ca. 5,000 years. A weakening and southward shift of the Southwest Indian Monsoon System, forced by northern hemisphere insolation variations in the precession band and/or glacial boundary conditions, is suggested as the mechanism for the abrupt shift to more arid conditions. Geoarchaeological evidence suggests that agriculture was more widespread and evolved alongside …

Evanescent Field Absorption Sensing Using Sapphire Fibers, Michael Grossman

USF Tampa Graduate Theses and Dissertations

This thesis explores the application of coiled sapphire multimode optical fibers for evanescent wave chemical sensing in both the visible spectrum and the near infrared. As has been suggested in the literature pertaining to silica fibers, bending converts low-order modes to high order ones, which leads to more evanescent absorption and thus a more sensitive chemical detector. By coiling the fiber many times, it was expected that even greater sensitivity would be attained.

Experiments were performed to investigate the sensor response to different solutions and to characterize this response. In the first of three experiments, the large absorption peak of …

Influence Of Evapotranspiration On Patterns Of Ground-Water Conductivity In Small Basins, Ana Jiménez

USF Tampa Graduate Theses and Dissertations

Ground-water conductivity data were obtained from shallow wells in a 12 km2 stream-basin along a 400 m transect, extending from the divide to the stream. The stream, Pringle Branch, is a second-order perennial stream in Hillsborough County, Florida. The shallow stratigraphy consists of 2-3 m of fine sand over a layer of clayey silt and silty clay. Vegetation cover includes grasses on the upper and middle slope, and riparian woodlands on the foot slope and floodplain. Precipitation is about 1.3 m per year. Shallow ground-water conductivity is about 50 uS/cm at the divide. It increases moderately along the mid slope, …

The John Muir University of the Pacific, Stocktoi, CA BER2/3 Sprint; Summer 2< John Muir's World Tour (part V) Lex Chalmers, University of Waikato, Hamilton, New Zealand Preface by W. R. Swagerty, Director, John Muir Center This past spring, I had the good fortune to travel to New Zealand and Australia through sponsorship of the J. William Fulbright Program of the U.S. State Department. At University of Waikato in Hamilton, New Zealand on the North Island, Dean Daniel Zirker introduced me to Professor Lex Chalmers, a distinguished geographer and researcher on his faculty. It turns out that Professor Chalmers had plans to travel to the United States on family business. After learning my interest in following John Muir's trail from his 1904 visit to New Zealand, Lex agreed to help with this project. In May, Chalmers visited us in Stockton and spent time in the John Muir Papers, clarifying the route and obtaining pertinent transcripts and details from the manuscripts. The document that resulted is his excellent work, not mine. I am indebted to Chalmers and the University of Waikato for the time spent helping the world better understand Muir's unpublished travels in New Zealand from the difficult-to-read notebooks that he kept while traveling abroad, and from Linnie Marsh Wolfe's transcriptions from the 1940s or 1950s. We are planning a more extensive academic publication from this preliminary work and share with you the fifth of six segments in the piece that follows. WRS John Muir's remarkable 'World Tour' began on May 29, 1903 with his departure from New York, and ended almost exactly a year later when he arrived back in San Francisco on May 27,1904. For most of this time Muir maintained a detailed daily journal, commenting on the botany, geomorphology and the patterns of human occupance that he encountered. These journals, closely written in pencil and often illustrated, are held in the Holt-Atherton Collection at the University of the Pacific in Stockton, Ca. The collection also holds some of Muir's correspondence written during his travels, and part of the Library collection he established. The journals have attracted scholarly attention, most notably in the transcription work undertaken by Linnie Marsh Wolfe to support her commentaries and 1946 biography of John Muir (Son of the Wilderness: The Life of John Muir). Wolfe's biography, not without its critics, place her at the forefront of commentators on John Muir's contribution to conservation, and her work was recognised by the award of the Pulitzer Prize for biography. Her typescript records of John Muir's journals are an important contribution and they provide the best research source for (Continued on page 6) page 1

The Impact Of Grey Literature In Advancing Global Karst Research: An Information Needs Assessment For A Globally Distributed Interdisciplinary Community, Todd A. Chavez, Anna H. Perrault, Pete Reehling, Courtney Crummett

Academic Resources Faculty and Staff Publications

A survey of the global karst community was conducted in 2006. The survey was distributed via the World Wide Web to known karst researchers. The instrument was designed to generate an initial inventory of core grey information types, to assess levels of usage of grey information by the respondents, and to gauge the karst community’s willingness to participate in building and expanding both this collection and the associated controlled vocabularies.
