Comparing Sulfur Transformations In Surface Soils Of Chattanooga Wetlands With Different Land Use Histories, Michael Mentz

Honors Theses

The purpose of this study was to assess whether high sulfur inputs in a local wetland had an effect on the functions of this wetland, i.e. an increased sulfate reduction rate and an increased sulfate concentration compared to a control wetland. Sulfate reduction rates were compared in two wetlands in Chattanooga, Tennessee during July and December 2007.These wetlands were known to have bad different histories of sulfur input via sulfates in precipitation or runoff.Through use of a 35S tracer technique, overall sulfate reduction rates could be compared for the two wetlands.Replicated sediment cores were collected from each wetland on the …

Excess 210Pb Inventories And Fluxes Along The Continental Slope And Basins Of The Gulf Of Papua, Zahid Muhammad, Samuel J. Bentley, Lawrence A. Febo, André W. Droxler, Gerald R. Dickens, Larry C. Peterson, Bradley N. Opdyke

Faculty Publications

Sediment samples were collected from continental slopes and marginal basins in the Gulf of Papua and analyzed for excess 210Pb to elucidate transport processes of fine-grained particles to this region. Estimated excess 210Pb fluxes of 1.0-12.8 dpm cm-2 a-1 were derived from measured seabed inventories. Highest sediment accumulation rates (0.28-0.35 cm a-) were measured along the northeastern shelf edge, and they decrease in seaward directions and along isobaths to the southwest. The excess 210Pb flux could result from either focused deposition of high-210Pb activity sediments from the continental shelf and upper slope or scavenging of 210Pb brought landward from deep-sea …

Late Pleistocene And Holocene Sedimentation, Organic-Carbon Delivery, And Paleoclimatic Inferences On The Continental Slope Of The Northern Pandora Trough, Gulf Of Papua, Lawrence A. Febo, Samuel J. Bentley, John H. Wrenn, André W. Droxler, Gerald R. Dickens, Larry C. Peterson, Bradley N. Opdyke

Faculty Publications

We investigated sediment and organic-carbon accumulation rates in two jumbo piston cores (MV-54, MV-51) retrieved from the midslope of the northeastern Pandora Trough in the Gulf of Papua, Papua New Guinea. Our data provide a first assessment of mass fluxes over the past ∼33,000 14C years B.P. and variations in organic-carbon sources. Core sediments were analyzed using a suite of physical properties, organic geochemistry, and micropaleontological measurements. MV-54 and MV-51 show two periods of rapid sediment accumulation. The first interval is from ∼15,000 to 20,400 Cal. years B.P. (MV-51: ∼1.09 in ka-1 and ∼81.2 g cm-2 ka-1) and the second …

An Evaluation And Implementation Guide For Current Groundwater Mass Flux Measurement Practices, Jack G. Wheeldon Iii

Theses and Dissertations

Contaminant mass flux is an important parameter needed for decision making at sites with contaminated groundwater. New and potentially better methods for measuring mass flux are emerging. This study looks at the conventional transect method (TM), and the newer passive flux meter (PFM), modified integral pump test (MIPT), and tandem circulating well (TCW) methods. In order to facilitate transfer and application of these innovative technologies, it is essential that potential technology users have access to credible information that addresses technology capabilities, limitations, and costs. This study provides such information on each of the methods by reviewing implementation practices and comparing …

Development Of An Ecological Model To Predict Risk For Acquisition Of Clostridium Difficile-Associated Diarrhea During Acute Care Hospitalization, Susan Elaine Steele

USF Tampa Graduate Theses and Dissertations

Background: The traditional model of infection control has failed to stop the spread of emerging infectious diseases such as Clostridium difficile-associated diarrhea (CDAD) in the acute care environment. Ecological models, which rely upon identification of susceptible hosts, offer an alternative to the prevention of deadly outbreaks. Previous epidemiological research has identified a number of risk factors associated with CDAD. Utilization of this body of research by nurses is limited due to methodological issues that introduce bias and confounding, and use of variables that have limited meaning to the practicing clinical nurse.

Aim: The aim of this study was to …

Emotion-Modulated Startle In Major And Minor Depression: The Role Of Mood Severity In Emotion Reactivity, April Taylor-Clift

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is a disorder defined by mood disturbance, but the deficits in emotional reactivity that accompany MDD are not yet fully characterized. Researchers have utilized the emotion-modulated startle paradigm to investigate emotional responding among depressed individuals with mixed results. Inconsistent results may be due in part to the heterogeneity of mood disorders, including variation in mood severity. The current study utilized an emotion-modulated startle procedure with 33 individuals currently experiencing a major depressive episode, 25 individuals currently experiencing a minor depressive episode (mD), and 31 healthy controls. Severity of depression, anxiety, and positive and negative mood states …

Tumor Suppressive Effects Of The Beta-2 Adrenergic Receptor And The Small Gtpase Rhob, Adam E. Carie

USF Tampa Graduate Theses and Dissertations

Receptor tyrosine kinases such as ErbB2 contribute greatly to human malignant transformation, but the role that other receptors such as ß2 adrenergic receptor (B2 AR)play in cancer is ill defined. Furthermore, while some GTPases such as Ras and RhoA promote oncogenesis, RhoB has been suggested to have tumor suppressive activity. In this thesis the tumor suppressive activity of ß2 adrenergic receptors through blockade of the Ras/Raf/Mek/Erk pathway is demonstrated. Furthermore, this thesis provides strong evidence in support of a tumor suppressive activity of RhoB, but not RhoA, in delaying EbB2 mammary oncogenesis in a transgenic mouse model.

The Role Of Perceptions Of Female Administrators Regarding The Gender Regimes In Urban Co-Educational Secondary Schools In Uganda, Frances Naluwemba

Theses and Dissertations

Leaders and policy makers in Uganda developed a national strategy of placing female administrators in traditionally male-dominated coeducational secondary schools in the belief that their vision would promote equitable education by changing gender regimes that play in schools. Gender regimes are patterns of gender arrangements that could disadvantage the education of boys or girls (Connell, 2002). The purpose of this study was to discover if female administrators perceived and had developed strategies to change gender regimes in their schools. Participants were 13 female administrators of government-supported coeducational mixed/day secondary schools in Kampala and Wakiso urban districts. Participants ranged in age …

Delineating Site-Specific Management Zones For Ph-Induced Iron Chlorosis, T. Kyaw, Richard B. Ferguson, Viacheslav I. Adamchuk, Dennis L. Mccallister, David B. Marx, D. D. Tarkalson

Department of Agronomy and Horticulture: Faculty Publications

Iron chlorosis can limit crop yield, especially on calcareous soil. Typical management for iron chlorosis includes the use of iron fertilizers or chlorosis tolerant cultivars. Calcareous and non-calcareous soil can be interspersed within fields. If chlorosisprone areas within fields can be predicted accurately, site-specific use of iron fertilizers and chlorosis-tolerant cultivars might be more profitable than uniform management. In this study, the use of vegetation indices (VI) derived from aerial imagery, on-the-go measurement of soil pH and apparent soil electrical conductivity (EC_a) were evaluated for their potential to delineate chlorosis management zones. The study was conducted at six …

Monte Carlo Calculations And Measurements Of Absorbed Dose Per Monitor Unit For The Treatment Of Uveal Melanoma With Proton Therapy, Nicholas Koch, Wayne D. Newhauser, Uwe Titt, Dan Gombos, Kevin Coombes, George Starkschall

Faculty Publications

The treatment of uveal melanoma with proton radiotherapy has provided excellent clinical outcomes. However, contemporary treatment planning systems use simplistic dose algorithms that limit the accuracy of relative dose distributions. Further, absolute predictions of absorbed dose per monitor unit are not yet available in these systems. The purpose of this study was to determine if Monte Carlo methods could predict dose per monitor unit (D/MU) value at the center of a proton spread-out Bragg peak (SOBP) to within 1% on measured values for a variety of treatment fields relevant to ocular proton therapy. The MCNPX Monte Carlo transport code, in …

Nano-Mechanical Properties Of Heat Inactivated Bacillus Anthracis And Bacillus Thuringiensis Spores, Jessica L. Poindexter

Theses and Dissertations

B. thuringiensis spores must have similar properties to B. anthracis spores to be a good simulant in counter-proliferation studies. In particular, they must behave in a similar way when exposed to high temperatures for short periods of time as would be caused by an explosion. This research project compares surface elasticities for four different spore sample types, B. anthracis spores, heat inactivated B. anthracis spores, B. thuringiensis spores, and heat inactivated B. thuringiensis spores. Heat inactivated spores were exposed to a temperature just high enough that no spores were observed to germinate. Elasticity values for the spore surfaces were determined …
