The Use Of Proteomic Techniques To Study The Physiology And Virulence Of Staphylococcus Aureus, Frances Rivera

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus

is a bacterial pathogen that is believed to be the most common agent of human infectious disease, causing conditions ranging from common skin lesions to life-threatening illnesses. S. aureus has also shown a remarkable ability to develop resistance to antimicrobial treatment, making infections difficult to treat. In the post-genomic era, proteomic studies analyzing the protein complement of a genome in a particular organism at any given time, have gained real significance. This result is largely due to dynamic changes in protein expression profiles which can lead wide alterations in physiology and behavior. For proteomics, it is necessary to …

The Monitoring And Evaluation Of Geothermal Systems, Whitney E. Maynard

USF Tampa Graduate Theses and Dissertations

With the heightened importance of green engineering in today’s society, harnessing the Earth’s internal energy has become ever more important. Specifically, the use of geothermal heat pumps as a means of heating and cooling homes and municipal buildings is on the rise. However, due to the high cost of installation and limited amount of research conducted, geothermal systems in the State of Florida have yet to meet their potential as an alternative heating and cooling source. With Florida’s relatively constant ground temperature of 72°F, an above average temperature gradient for both heating and cooling of indoor areas is provided. To …

From Night To Dawn: The Cultural Criticism Of George A. Romero, Christopher Paul Wagenheim

USF Tampa Graduate Theses and Dissertations

Analyzing George A. Romero's Night of the Living Dead (1968) and Dawn of the Dead (1978) in relation to the early works of Marshal McLuhan, Erich Fromm, and Herbert Marcuse reveals an ideological parallel that can be explicated using Antonio Gramsci's theory of cultural hegemony. While McLuhan, Marcuse, and Fromm observe, in order to critique, social manifestations of power in a consumerist system, Romero presents a model of hegemony in his films that he exposes to extreme stress thereby allowing viewers to observe such manifestations of power for themselves. These analyses are significant because although Marcuse, McLuhan, Fromm, and Romero …

Ballistic Penetration Of A Sandbagged Redoubt Using Silica Sand And Pulverized Rubber Of Various Grain Sizes, Robert Paul Cole

USF Tampa Graduate Theses and Dissertations

The basis of this work is to find how varying the grain size of materials contained in sandbags (sand and crumb rubber) effects the ballistic penetration of the projectiles from both the 7.62x39mm (308-short), and 9mm Luger cartridges. The sandbags were stacked in a pyramidal stacking configuration according to military specifications in order to simulate a section of a sandbag barrier or redoubt as would be seen on the battlefield. The projectiles were fired at the targets, and the velocity and penetration data was recorded. The results concern both military and civilian applications alike. The 7.62x39 round was found to …

Does Patient Dementia Limit The Use Of Cardiac Catheterization In St-Elevated Myocardial Infarction?, Marianne Chanti-Ketterl

Regardless of age or mental capacity, percutaneous coronary intervention (PCI) is the first line of treatment for ST-elevated myocardial infarction (STEMI). This study evaluates the disparities in the use of diagnostic cardiac catheterization and PCI in STEMI patients with dementia. A retrospective analysis was performed of Florida‟s comprehensive inpatient surveillance system for the years 2006-2007 with admission diagnosis of STEMI. Logistic regression analysis was used to identify disparities in the use of intervention among all STEMI patients. A total of 8,331 STEMI patients met the inclusion criteria. Of these, 77% were catheterized and of these 67% received PCI. A total …

A Novel Approach To X-Ray Mirror Bending Stability And Control, Michael Weinbaum

USF Tampa Graduate Theses and Dissertations

A novel, no-contact approach to X-ray mirror bending control is presented here,

proposed for use on the beamlines of the European X-ray Free Electron Laser (XFEL)

project. A set of mirrors with tunable bending radii are desired, that will maintain their

optical properties even as the beam incidence causes local heating. Various mechanical

bending mechanisms have been proposed and used on other beamlines, which can take up

a lot of physical space, demanding more vacuum power, while using expensive high

precision servomotors. Rather than bend the mirror by mechanical means, it is proposed

to heat the mirror to produce the …

Dynamics Of Teacher Self-Efficacy: Middle School Reading And Language Arts Teacher Responses On A Teacher Sense Of Efficacy Scale, Kimberly Ann Schwartz

USF Tampa Graduate Theses and Dissertations

Efficacy is created early in a career and not easily influenced over time yet states and school districts loose tremendous amounts of money annually educating and training teachers who elect to leave the profession as a result of low self-efficacy. The purpose of this study was to examine the perceived levels of self-efficacy of middle school Language Arts and reading teachers at various stages in their teaching careers in an attempt to inform the practices of teacher preparation. The Teacher Sense of Efficacy Scale along with a Teacher Demographic Survey was used to identify how preparation method, content area, and …

Investigating The Mode Of Action Of A Novel N-Sec-Butylthiolated Beta-Lactam Against Staphylococcus Aureus, Katherine Rose Prosen

USF Tampa Graduate Theses and Dissertations

N-sec

-butylthioloated β-lactam (NsβL) is a novel beta-lactam antimicrobial with a mechanism of action proposed to inhibit 3-oxoacyl-acyl carrier protein synthase (ACP) III (FabH), resulting in the inhibition of fatty acid synthesis. It has been suggested that NsβL inhibits FabH indirectly by inactivating coenzyme-A (CoA). CoA is an essential cofactor for numerous proteins involved in glycolysis, the citric acid cycle (TCA), and pyruvate metabolism, in addition to fatty acid biosynthesis. This study aimed to determine the effects of NsβL on a diverse array of laboratory and clinical Staphylococcus aureus isolates by analyzing the mode of resistance in spontaneous and adaptive …

Thermal Conductivity Of Soils From The Analysis Of Boring Logs, Nicole M. Pauly

USF Tampa Graduate Theses and Dissertations

Recent interest in "greener" geothermal heating and cooling systems as well as developments in the quality assurance of cast-in-place concrete foundations has heightened the need for properly assessing thermal properties of soils. Therein, the ability of a soil to diffuse or absorb heat is dependent on the surrounding conditions (e.g. mineralogy, saturation, density, and insitu temperature). Prior to this work, the primary thermal properties (conductivity and heat capacity) had no correlation to commonly used soil exploration methods and therefore formed the focus of this thesis.

Algorithms were developed in a spreadsheet platform that correlated input boring log information to thermal …

The Design And Synthesis Of Functionalized Porphyrins And Their Applications In Group Transfer Reactions, Medicine, And Materials, Kimberly Bliss Fields

USF Tampa Graduate Theses and Dissertations

Porphyrins and their analogs are a class of chemically and biologically important compounds that have found a variety of applications in different fields such as catalysis, medicine, and materials. The physical, chemical, and biological dependence of the peripheral substituents of porphyrins on their properties has prompted great effort towards the synthesis of new porphyrins with different electronic, steric, and conformational environments. To this end, porphyrins have been prepared using a modular approach from bromo- and triflate synthons. These synthons underwent palladium-catalyzed cross-coupling with chiral amines, amides, alcohols, and boronic esters to create products that were tested for biological activity.

Metalloporphyrins …

Analysis Of Stochastic Disruptions To Support Design Of Capacitated Engineered Networks, Andrés Fernando Uribe-Sánchez

USF Tampa Graduate Theses and Dissertations

This work is a compilation of four manuscripts, three of which are published and one is

in the second round of review, all in refereed journals. All four manuscripts focus on analysis

of stochastic disruptions to support design of capacitated engineered networks. The work

is motivated by limited ability to mitigate elevated risk exposure of large-scale capacitated

enterprise networks functioning in lean environments. Such inability to sustain enterprise

capacity in the face of disruptions of various origins has been causing multi-billion enterprise

forfeitures and hefty insurance premiums. At the same time, decision support methodologies

for reliable design of dynamic capacitated …

Synthesis Of Functionalized Resorcin[4]Arene Via Click Chemistry, Ali Husain

USF Tampa Graduate Theses and Dissertations

Click chemistry is a very powerful chemical strategy that overcome carbon-carbon bond with carbon-heteroatom bond by joining small units with heteroatom links (C-X-C) using spring-loaded reactants. The Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition is a major example based on the click chemistry philosophy. This method was used for the last 10 years to join different functional groups, carbohydrates, aminoacids, polymers to calix[4]arene and resorcin[4]arene cavitands by a stable 1,2,3-triazole linkages.

Herein I describe our interest in this type of click chemistry reaction in the synthesis of dimeric capsules resorcin[4]arene via four 1,2,3-triazole linkages. Two different resorcin[4]arene derivatives were synthesized in which four …

Phenotypic And Genotypic Analysis Of In Vitro Selected Artemisinin Resistant Plasmodium Falciparum, Matthew Scott Tucker

USF Tampa Graduate Theses and Dissertations

Artemisinin and its derivatives provide faster clearance of parasitemia than any other antimalarial drugs and these drugs are part of frontline combination therapies in areas where drug-resistant Plasmodium falciparum exists. Clinical resistance to artemisinins is emerging on the Thailand-Cambodia border, making it imperative to investigate mechanisms of artemisinin resistance. Previous work in our laboratory showed ring-stage parasites enter a dormant state after exposure to artemisinin. We hypothesize that this period of dormancy is directly related to recrudescence and prolonged parasite clearance times in patients, and possibly resistance. The target of artemisinin is currently unknown, and potential resistance mechanisms are not …

Gender And Cocaine Use Influence The Expression Of Urinary Markers Of Inflammation And Oxidative Stress, Marie Meagher Bourgeois

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate whether or not gender differences may be present in the expression of a number of urinary proteins which may serve as markers of inflammation and oxidative stress. Males and females have different patterns of illness and different life spans, suggesting basic biological traits exert significant control on the incidence of rhabdomyolysis, renal failure, atherosclerosis, myocardial ischemia, myocardial contraction band formation, autoimmune disorders and general inflammatory diseases. Men are at greater risk for cardiovascular disease; however women, particularly elderly women, have higher fatality rates due to heart failure. Renal diseases progress far more …
