Rh Glycoprotein As An Ammonia Transport Molecule, Matthew B. Phillips

College of Graduate Studies: Theses & Dissertations

Fish use their gills to excrete ammonia in order to eliminate nitrogenous waste. We hypothesize that this mechanism is accomplished by one or more transport proteins in the Rh glycoprotein (RhxG) family. Longhorn sculpin (Myoxocephalus octodecemspinosus) cDNA was amplified using polymerase chain reaction (PCR) and then the PCR products were visualized on an agarose gel. The cDNA from the gel bands was then sequenced and the gene sequence fragments were assembled and completed by rapid amplification of the cDNA ends (RACE). By this process we have obtained large portions of the gene sequences of the four known paralogues located in …

Impacts Of Laurel Wilt Disease On Redbay (Persea Borbonia) Population Structure And Forest Communities In The Coastal Plain Of Georgia, Usa, Kimberly S. Spiegel

College of Graduate Studies: Theses & Dissertations

Laurel wilt disease (LWD), a fungal disease vectored by the non-native redbay ambrosia beetle (Xyleborus glabratus), has caused mortality of redbay (Persea borbonia) in the Coastal Plain of Georgia, USA, since 2003. This disease has spread 30-100 km/year and little research has evaluated its impacts on redbay population structure and forest communities. Healthy and infested populations of redbay and their associated communities were compared in five sites infested with LWD and three un-infested sites in five counties in Georgia. Tree, shrub, and herb layers were sampled separately to determine redbay population structure and community composition and structure. Only 8% of …

Students were assessed (at different stages during the module) by evaluation of a written research proposal planner document, a reflective PowerPoint presentation and a final written research project proposal. The contribution reflects on the module …

The Liberal Gene: Sociobiology As Emancipatory Discourse In The Late Soviet Union, Yvonne Howell

Languages, Literatures, and Cultures Faculty Publications

In the following analysis, we will find that Soviet sociobiology did not develop incrementally out of daring interdisciplinary probes; rather, it seemed to spring forth fully formulated in the comprehensive Novyi mir article. Moreover, already in 1971, several years before Wilson's book established its controversial eponymous discipline in the United States, the biosocial paradigm was framed by its earliest Soviet proponents as a scientific vindication for diversity, pluralism, individual difference, heterogeneity, human rights, and ultimately, individual responsibility for one's own actions. In short, the same scientific discipline that in the west was associated with racism, reductionism, and social determinism developed …

Husbandry Of Monodelphis Domestica In The Study Of Mammalian Embryogenesis, Holly Rousmaniere, Rachel Silverman, Rachel A. White, Mark M. Sasaki, Siobhan D. Wilson, Jeremy T. Morrison, Yolanda P. Cruz

Faculty & Staff Scholarship

Monodelphis domestica, commonly called the laboratory opossum, is a useful laboratory animal for studying marsupial embryogenesis and mammalian development. Females breed year-round and the animals can be sustainably bred indoors. The authors draw on their own laboratory's experience to supplement previously published research on laboratory opossums. They describe a breeding protocol that reliably produces timed-pregnant M. domestica. Additionally, the authors discuss general laboratory opossum husbandry techniques and describe how to collect, handle and culture embryos.

Academic Analytics And Data Mining In Higher Education, Paul Baepler, Cynthia James Murdoch

International Journal for the Scholarship of Teaching & Learning

The emerging fields of academic analytics and educational data mining are rapidly producing new possibilities for gathering, analyzing, and presenting student data. Faculty might soon be able to use these new data sources as guides for course redesign and as evidence for implementing new assessments and lines of communication between instructors and students. This essay links the concepts of academic analytics, data mining in higher education, and course management system audits and suggests how these techniques and the data they produce might be useful to those who practice the scholarship of teaching and learning.

Lps-Induced Production Of Inflammatory Mediators In The Liver Of Postnatal Animals, Valerie P. Le Rouzic

Seton Hall University Dissertations and Theses (ETDs)

Lipopolysaccharide (LPS) is the primary component of the outer membrane of Gram-negative bacteria and is responsible for the majority of inflammatory effects of infections from Gram-negative bacteria. To gain better understanding of the effects that postnatal age has on the inflammatory response, pups were randomly assigned to be treated with 250 µg/kg of LPS or saline at postnatal day (P) 1, P21, and P70. Two hours post stimulation, the pups were sacrificed and their livers were harvested for total RN A extraction. Relative mRNA levels of inflammatory genes and �-actin were determined using RT-PCR analysis with appropriate rat sense and …

Simulation Studies Of Pulsed Voltage Effects On Cells, Jiahui Song

Electrical & Computer Engineering Theses & Dissertations

This dissertation research focuses on the new field of pulsed electric field interactions with biological cells. In particular, "Intracellular Electromanipulation" which has important biomedical applications, is probed. Among the various aspects studied, nanosecond, high-intensity pulse induced electroporation is one phenomena. It is simulated based on a coupled scheme involving the current continuity and Smoluchowski equations. A dynamic pore model can be achieved by including a dependence on the pore population density and a variable membrane tension. These changes make the pore formation energy E(r) self-adjusting and dynamic in response to pore formation. Additionally, molecular dynamics (MD) simulations are also discussed …

Simultaneous Higher Harmonic Detection And Extraction Of Information From Oxygen Spectra, Karan Dineshchandra Mohan

Electrical & Computer Engineering Theses & Dissertations

Wavelength Modulation Spectroscopy (WMS) is a highly sensitive technique that utilizes synchronous detection at the N-th harmonics of a modulating frequency, by modulating the laser beam used to probe a gaseous species. The advantage of this technique lies in the greater effective signal-to-noise ratio one obtains as a direct consequence of the larger amount of structure present in the higher harmonics, and thus a greater amount of information that can be obtained from that structure. We present the development of a novel technique where data at multiple harmonics is obtained simultaneously, rather than sequentially. This removes the susceptibility of the …

Analysis And Optimization Of Dynamic Spectrum Sharing For Cognitive Radio Networks, Manish Wadhwa

Electrical & Computer Engineering Theses & Dissertations

The goal of this dissertation is to present the analysis and optimization of dynamic spectrum sharing for cognitive radio networks (CRNs). Spectrum scarcity is a well known problem at present. In order to deal with this problem, dynamic spectrum sharing (DSS) was proposed. DSS is a technique where cognitive radio networks dynamically and opportunistically share the channels with primary users. The major contribution of this dissertation is in analyzing the problem of dynamic spectrum sharing under different scenarios and developing optimal solutions for these scenarios. In the first scenario, a contention based dynamic spectrum sharing model is considered and its …

On The Sampling Of Web Images For Learning Visual Concept Classifiers, Shiai Zhu, Gang Wang, Chong-Wah Ngo, Yu-Gang Jiang

Research Collection School Of Computing and Information Systems

Visual concept learning often requires a large set of training images. In practice, nevertheless, acquiring noise-free training labels with sufficient positive examples is always expensive. A plausible solution for training data collection is by sampling the largely available user-tagged images from social media websites. With the general belief that the probability of correct tagging is higher than that of incorrect tagging, such a solution often sounds feasible, though is not without challenges. First, user-tags can be subjective and, to certain extent, are ambiguous. For instance, an image tagged with “whales” may be simply a picture about ocean museum. Learning concept …

Analytics-Modulated Coding Of Surveillance Video, Lai-Tee Cheok, Nikhil Gagvani

Research Collection School Of Computing and Information Systems

Video surveillance systems increasingly use H.264 coding to achieve 24x7 recording and streaming. However, with the proliferation of security cameras, and the need to store several months of video, bandwidth and storage costs can be significant. We propose a new compression technique to significantly improve the coding efficiency of H.264 for surveillance video. Video content is analyzed and video semantics are extracted using video analytics algorithms such as segmentation, classification and tracking. In contrast to existing approaches, our Analytics-Modulated Compression (AMC) scheme does not require coding of object shape information and produces bitstreams that are standards-compliant and not limited to …

Prognosis For Ecosystem Recovery Following Rodent Eradication And Seabird Restoration In An Island Archipelago, Holly P. Jones

Faculty Articles, Papers, and Other Scholarship

Invasive species are widespread and can have devastating effects on biota, especially insular biota. Invasive species eradications are increasingly employed to promote island recovery to preinvasion states. However, it remains unclear if additional restoration actions may be required on islands that were once heavily reliant on seabird guano for ecosystem functions. Active seabird augmentation has been suggested as necessary to exact ecosystem recovery on contemporary timescales in some cases. I use two experiments on offshore islands in Cook Strait, New Zealand, to test the hypothesis that seabird restoration will restore island ecosystem functioning following invasive rodent removal. The first is …

Synaptotoxicity Of Alzheimer Beta Amyloid Can Be Explained By Its Membrane Perforating Property, Fernando Sepulveda, Jorge Parodi, Robert W. Peoples, Carlos Opazo, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

The mechanisms that induce Alzheimer’s disease (AD) are largely unknown thereby deterring the development of disease-modifying therapies. One working hypothesis of AD is that Aβ excess disrupts membranes causing pore formation leading to alterations in ionic homeostasis. However, it is largely unknown if this also occurs in native brain neuronal membranes. Here we show that similar to other pore forming toxins, Aβ induces perforation of neuronal membranes causing an increase in membrane conductance, intracellular calcium and ethidium bromide influx. These data reveal that the target of Aβ is not another membrane protein, but that Aβ itself is the cellular target …

Involvement Of Noradrenergic Neurotransmission In The Stress- But Not Cocaine-Induced Reinstatement Of Extinguished Cocaine-Induced Conditioned Place Preference In Mice: Role For Β-2 Adrenergic Receptors, John R. Mantsch, Andy Meyer, Oliver Vranjkovic, Chad E. Beyer, David A. Baker, Holly Caretta

Biomedical Sciences Faculty Research and Publications

The responsiveness of central noradrenergic systems to stressors and cocaine poses norepinephrine as a potential common mechanism through which drug re-exposure and stressful stimuli promote relapse. This study investigated the role of noradrenergic systems in the reinstatement of extinguished cocaine-induced conditioned place preference by cocaine and stress in male C57BL/6 mice. Cocaine- (15 mg/kg, i.p.) induced conditioned place preference was extinguished by repeated exposure to the apparatus in the absence of drug and reestablished by a cocaine challenge (15 mg/kg), exposure to a stressor (6-min forced swim (FS); 20–25°C water), or administration of the α-2 adrenergic receptor (AR) antagonists yohimbine …

Malaria In Prehistoric Sardinia (Italy): An Examination Of Skeletal Remains From The Middle Bronze Age, Teddi J. Setzer

USF Tampa Graduate Theses and Dissertations

Sardinia was an island with a history of a malarious environment until eradication efforts were conducted from 1946 to 1950. While historic documents suggest the disease was introduced from North Africa around 500 BC, no study has been conducted to test for the presence of malaria in prehistoric native populations, such as the Nuragic people of the Bronze Age. However, it has been suggested that aspects of the Nuragic culture, for example the stone structures found throughout the island, are adaptations to a malarious environment. The purpose of this dissertation is to test the hypothesis that malaria was present in …

The Accidental Practitioner: Principles Of Rational Emotive Behavior Therapy In The Works Of Kurt Vonnegut, Joseph J. Ward

USF Tampa Graduate Theses and Dissertations

Just as psychology and philosophy have influenced the field of literary studies, literature provides insight about the theories and practices of its sister disciplines. The purpose of this thesis is to demonstrate how literary works of Kurt Vonnegut illuminate principles of the influential branch of psychotherapy known as Rational Emotive Behavior Therapy (REBT).

This thesis traces the similar philosophies and shared beliefs of Vonnegut and REBT's founder, Albert Ellis, and details how Ellis's REBT is illustrated in selected works of Vonnegut, specifically, Slaughterhouse-Five, Breakfast of Champions, Galapagos, and Timequake. The thesis concludes by suggesting that Vonnegut's …

An Ecology Of Performance: Gregory Bateson's Cybernetic Performance, Daniel Matthew Blaeuer

USF Tampa Graduate Theses and Dissertations

This dissertation is a case study of the public performances of Gregory Bateson at The Esalen Institute. The case study is a reconsideration of the work of Gregory Bateson from the perspective of performance studies. The author brings together performativity, cybernetics, and the sacred to argue that Gregory Bateson, in his public performances, was striving for grace in encounters with others. The author has conducted archival research into Bateson’s presentations and has spoken with several close to Bateson to get a sense of how his process of public presentation paralleled his ideas—a process of continually working through ideas in conversation …

Bastards, Brains, Boobs And Performance: A Retrospective Account, Joanna Bartell

USF Tampa Graduate Theses and Dissertations

The two essays that comprise this thesis use personal narrative to discuss various aspects of illness, resistance and the body. The first essay uses performance theory to explore the social structures, mandates and restrictions concerning illness. I use the cancer experience to explore the co-creation of self, identity, and modes of being between "performer" and "audience." "Performer," in this case, is the "breast cancer patient," and the "audience" is comprised of the "social others.” The second essay explores cyborgization of the body, its painful effects, and associated social and moral values. It also discusses how we create theory and understanding …

An Integrated Building Water Management Model For Green Building, Caryssa Joustra

USF Tampa Graduate Theses and Dissertations

The U.S. Green Building Council (USGBC) is the developer of the Leadership in Energy and Environmental Design (LEED™) green building scoring system. On first inspection of LEED points, few address water efficiency. However, water management encompasses other points beyond the Water Efficiency (WE) category. In general, the industry is apt to take a somewhat compartmentalized approach to water management. The use of alternative water sources or the reuse of wastewater significantly complicates the water budget picture. A total water management systems approach, taking into consideration water from various sources, both inside and outside the building, should be implemented in order …

Comparing Discrete Simulation And System Dynamics: Modeling An Anti-Insurgency Influence Operation, Wayne Wakeland, Una E. Medina

Complex Systems Faculty Publications and Presentations

This paper contrasts the tradeoffs of modeling the same dynamic problem at a micro scale and at a macro scale of analysis: discrete system simulation (DS) versus continuous system simulation or system dynamics (SD). Both are employed to model the influence of entertainment education on terrorist system decay, with implications for field application. Each method optimizes different design, scope/scale, data availability/accuracy, parameter settings, and system sensitivities. Whether the research served by the computer model is applied or theoretical, DS tends to be useful for understand low-level individual unit/step influences on system change over time, whereas SD tends to shine when …

Why Farm The City? Theorizing Urban Agriculture Through A Lens Of Metabolic Rift, Nathan Mcclintock

Urban Studies and Planning Faculty Publications and Presentations

Urban agriculture (UA) is spreading across vacant and marginal land worldwide, embraced by government and civil society as source of food, ecosystems services and jobs, particularly in times of economic crisis. ‘Metabolic rift' is an effective framework for differentiating UA's multiple origins and functions across the Global North and South. I examine how UA arises from three interrelated dimensions of metabolic rift—ecological, social and individual. By rescaling production, reclaiming vacant land and ‘de-alienating’ urban dwellers from their food, UA also attempts to overcome these forms of rift. Considering all three dimensions is valuable both for theory and practice.

Symmetries Of The Central Vestibular System: Forming Movements For Gravity And A Three-Dimensional World, Gin Mccollum, Douglas Hanes

Mathematics and Statistics Faculty Publications and Presentations

Intrinsic dynamics of the central vestibular system (CVS) appear to be at least partly determined by the symmetries of its connections. The CVS contributes to whole-body functions such as upright balance and maintenance of gaze direction. These functions coordinate disparate senses (visual, inertial, somatosensory, auditory) and body movements (leg, trunk, head/neck, eye). They are also unified by geometric conditions. Symmetry groups have been found to structure experimentally-recorded pathways of the central vestibular system. When related to geometric conditions in three-dimensional physical space, these symmetry groups make sense as a logical foundation for sensorimotor coordination.

Short-Chain Carboxylic Acids From Gray Catbird (Dumetella Carolinensis) Uropygial Secretions Vary With Testosterone Levels And Photoperiod, Rebecca J. Whelan, Tera C. Levin, Mary C. Garvin

Faculty & Staff Scholarship

The uropygial gland of birds produces secretions that are important in maintaining the health and structural integrity of feathers. Non-volatile components of uropygial secretions are believed to serve a number of functions including waterproofing and conditioning the feathers. Volatile components have been characterized in fewer species, but are particularly interesting because of their potential importance in olfactory interactions within and across species. We used solid-phase microextraction headspace sampling with gas chromatography-mass spectrometry to detect and identify volatiles in uropygial secretions of gray catbirds (Dumetella carolinensis), a North American migratory bird. We consistently detected the following carboxylic acids: acetic, …
