A Study On The Adaptability Of Immune System Principles To Wireless Sensor Network And Iot Security, Vishwa Alaparthy

USF Tampa Graduate Theses and Dissertations

Network security has always been an area of priority and extensive research. Recent years have seen a considerable growth in experimentation with biologically inspired techniques. This is a consequence of our increased understanding of living systems and the application of that understanding to machines and software. The mounting complexity of telecommunications networks and the need for increasing levels of security have been the driving factor. The human body can act as a great role model for its unique abilities in protecting itself from external, foreign entities. Many abnormalities in the human body are similar to that of the attacks in …

Maternal Sexuality During Lactation: The Influence Of Breastfeeding Recency And Relationship Quality, Melissa A. Eaton

Psychology ETDs

Introduction. During lactation, breastfeeders report reduced sexual desire and sexual activity (Von Sydow, 1999). Yet research has not examined the direct impact of suckling on sexuality during lactation. This study looked at breastfeeders, immediately following breastfeeding and several hours later, to determine if the recency of infant suckling influences maternal sexuality. Sexual motivations were also compared between breastfeeders and other mothers. Methods. Mothers of infants between 2 and 7 months of age participated in the repeated measures study online. Participants were randomly assigned to the order of their sessions and participated 20 minutes after breastfeeding or 120 minutes after …

Amazing Facts About The Jfk Assassination, Donald E. Wilkes Jr.

Popular Media

During the past half century, resourceful scholars, journalists and private researchers within the JFK assassination research community, to their enormous credit, repeatedly have uncovered relevant evidence unavailable or overlooked during the official investigations. The members of this research community are the persons who have been the most active in examining the millions of pages of previously secret government documents relating to the assassination that have been declassified and released to the public since 1992.

While many key factual questions about the JFK assassination remain answered, we now, in 2018, know more of the facts surrounding the assassination than ever before. …

Development Of Functional Chemical Probes For The Study Of Viscosity, Fe(Ii), And Ferroptosis And Photo-Triggered Drug Delivery, Yongyi Wei

Chemistry and Chemical Biology ETDs

Small molecule probes are useful tools for the study of biology. In particular, the dye derived fluorescence probes enable to spatiotemporally monitor the events of analytes of interest. The noninvasive feature is particularly attractive for the biological studies in live cells. The challenge is to develop chemical probes capable of detection of the analyte of interest with high specificity.

Toward this end, my Ph. D. study centers on the development of novel chemical probes for the study and understanding of the alternation of important cellar contents and substances and their functions and relationship between normal and disease states. In the …

Acoustofluidics And Soft Materials Interfaces For Biomedical Applications, Frank A. Fencl

Biomedical Engineering ETDs

This dissertation describes fabrication of devices and other tools for biomedical applications through the integration of acoustofluidic systems with bio separation assays, instrumentation components, and soft materials interfaces. For example, we engineer a new class of transparent acoustic flow chambers ideal for optical interrogation. We demonstrate efficacy of these devices by enhancing the signal for high throughput acoustic flow cytometry, capable of robust particle focusing across multiple parallel flowing streams. We also investigate an automated sampling system to determine the parameters of transient particle stream focusing in between sample boluses and air bubbles to model a high throughput, multi-sampling acoustic …

Body And Time: The Temporality Of Human Embodiment, Daniel Harland Briggs Jr.

Philosophy ETDs

In this dissertation I hope to shed further light on Heidegger’s thought-provoking claim that “We do not “have” a body; rather, we “are” bodily.” After discussing the problem of the body in the context of Being and Time in chapters one and two, I move to Heidegger’s later lectures and seminars in chapter three to articulate a specifically Heideggerian account of the bodying of the body. I hope to show that Heidegger’s understanding of the ontological difference can effectively help us to understand bodily difference in its corporeal, lived, and existential dimensions. From a Heideggerian standpoint, the existential dimensions of …

Water, Energy, And Carbon Footprints Of Bioethanol From The U.S. And Brazil, Mesfin Mekonnen, Thiago L. Romanelli, Chittaranjan Ray, Arjen Y. Hoekstra, Adam Liska, Christopher M. U. Neale

Adam Liska Papers

Driven by biofuel policies, which aim to reduce greenhouse gas (GHG) emissions and increase domestic energy supply, global production and consumption of bioethanol have doubled between 2007 and 2016, with rapid growth in corn-based bioethanol in the U.S. and sugar cane-based bioethanol in Brazil. Advances in crop yields, energy use efficiency in fertilizer production, biomass-to-ethanol conversion rates, and energy efficiency in ethanol production have improved the energy balance and GHG emission reduction potential of bioethanol. In the current study, the water, energy, and carbon footprints of bioethanol from corn in the U.S. and sugar cane in Brazil were assessed. The …

Hnrnpa2 Mediated Acetylation Reduces Telomere Length In Response To Mitochondrial Dysfunction, Manti Guha, Satish Srinivasan, F. Bradley Johnson, Gordon Ruthel, Kip Guja, Miguel Garcia-Diaz, Brett A. Kaufman, M. Rebecca Glineburg, Jikang Fang, Hiroshi Nakagawa, Jeelan Basha, Tapas Kundu, Narayan G. Avadhani

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Telomeres protect against chromosomal damage. Accelerated telomere loss has been associated with premature aging syndromes such as Werner’s syndrome and Dyskeratosis Congenita, while, progressive telomere loss activates a DNA damage response leading to chromosomal instability, typically observed in cancer cells and senescent cells. Therefore, identifying mechanisms of telomere length maintenance is critical for understanding human pathologies. In this paper we demonstrate that mitochondrial dysfunction plays a causal role in telomere shortening. Furthermore, hnRNPA2, a mitochondrial stress responsive lysine acetyltransferase (KAT) acetylates telomere histone H4at lysine 8 of (H4K8) and this acetylation is associated with telomere attrition. Cells containing dysfunctional mitochondria …

Novel Pleiotropic Risk Loci For Melanoma And Nevus Density Implicate Multiple Biological Pathways, David L Duffy, Gu Zhu, Xin Li, Marianna Sanna, Mark M Iles, Leonie C Jacobs, David M Evans, Seyhan Yazar, Jonathan Beesley, Matthew H Law, Peter Kraft, Alessia Visconti, John C Taylor, Fan Liu, Margaret J Wright, Anjali K Henders, Lisa Bowdler, Dan Glass, M Arfan Ikram, André G Uitterlinden, Pamela A Madden, Andrew C Heath, Elliot C Nelson, Adele C Green, Stephen Chanock, Jennifer H Barrett, Matthew A Brown, Nicholas K Hayward, Stuart Macgregor, Richard A Sturm, Alex W Hewitt, Manfred Kayser, David J Hunter, Julia A Newton Bishop, Timothy D Spector, Grant W Montgomery, David A Mackey, George Davey Smith, Tamar E Nijsten, D Timothy Bishop, Veronique Bataille, Mario Falchi, Jiali Han, Nicholas G Martin

A Web-Based Calculator For The Prediction Of Severe Neurodevelopmental Impairment In Preterm Infants Using Clinical And Imaging Characteristics, Zachary A Vesoulis, Nathalie M El Ters, Maja Herco, Halana V Whitehead, Amit M Mathur

Open Access Publications

Although the most common forms of brain injury in preterm infants have been associated with adverse neurodevelopmental outcomes, existing MRI scoring systems lack specificity, do not incorporate clinical factors, and are technically challenging to perform. The objective of this study was to develop a web-based, clinically-focused prediction system which differentiates severe neurodevelopmental outcomes from normal-moderate outcomes at two years. Infants were retrospectively identified as those who were born ≤30 weeks gestation and who had MRI imaging at term-equivalent age and neurodevelopmental testing at 18⁻24 months. Each MRI was scored on injury in three domains (intraventricular hemorrhage, white matter injury, and …

Islas De Las Californias, Colaboración Botánica: Islands Of The Californias Botanical Collaborative, William Hoyer, John Knapp, Denise Knapp, David Mazurkiewicz, Ken Owen, Luciana Luna-Mendoza, Kathryn Mceachern

Western North American Naturalist

After nearly 2 centuries of being negatively impacted, primarily by introduced mainland vertebrates, the unique flora and vegetation of the Islands of the Californias archipelago have been severely degraded. The botanical conservation challenges that lie ahead include the near extinction or extirpation of rare, endemic, and even common plant taxa; invasion of nonnative plants; near loss of unique island vegetation communities; and the degradation of a host of sites. These challenges are too large for any one entity to remedy alone. Many of the botanical resources impacted are found on multiple islands and cross political boundaries. The Islands of the …

Imaging Innovations For Whole-Slide And Hyperspectral Microscopy, Jun Liao

Doctoral Dissertations

Digital pathology via whole-slide imaging (WSI) systems has recently been approved for the primary diagnostic use in the US. A critical challenge of WSI is to perform accurate focusing in high speed. Traditional systems create a focus map prior to scanning. For each focus point on the map, a sample needs to be static in the x-y plane, and axial scanning is needed to maximize the contrast. Here I report a novel focus map surveying method for WSI. In this method, I use two LEDs to illuminate the sample and recover the focus points based on 1D autocorrelation analysis. The …

Investigating The Roles Of Fucosylation And Calcium Signaling In Melanoma Invasion, Tyler S. Keeley

USF Tampa Graduate Theses and Dissertations

Melanoma is the deadliest form of skin cancer. Prognosis for early stage melanoma patients is excellent, and surgery is often curative for these patients. However, once patients have presented with invasive disease, the average 5-year survival rate drops significantly from over 90% to between 10 and 15%. Several therapies have been developed to target a commonly mutated oncogene BRAF, or its downstream effectors. Unfortunately, while these treatments show robust initial response, most patients relapse within a year. Moreover, therapy-resistant tumors are often more invasive and metastatic. Therefore, it is important to investigate the molecular mechanisms underlying melanoma invasion and metastasis, …

Early Identification Of Students In Accelerated Curricula With Signs Of Academic And Emotional Risk: Working With Teachers To Identify At-Risk Students, Elizabeth D. Storey

USF Tampa Graduate Theses and Dissertations

As part of a comprehensive, multi-tiered system of support for students’ emotional, academic, and behavioral success, effective universal screenings are essential to identify students who may benefit from early intervention and targeted prevention services (Strein, Kuhn-McKearin, & Finney, 2014). Although many screening procedures and methods have been developed and evaluated for general education populations, more research is needed on screening procedures designed for one traditionally underserved population in school-based mental health services—students in accelerated curricula (namely, students in Advanced Placement classes or in the International Baccalaureate program; AP/IB). When teachers are involved in universal screening procedures, regardless of student population …

Behavioral Thermoregulation And Thermal Mismatches Influence Disease Dynamics In Amphibians, Erin Louise Sauer

USF Tampa Graduate Theses and Dissertations

Amphibians are currently the most threatened vertebra taxa on the planet. Hundreds of species are thought to have gone extinct while thousands more have been listed as threatened or endangered over the past few decades. Habitat loss, invasive species, climate change, and disease are all thought to have partially contributed to these declines. Two pathogens in particular, infectious viruses in the genus Ranavirus (simply referred to as ranavirus) and the fungus Batrachochytrium dendrobatidis (Bd), have been associated with global mass mortality events of amphibians. Virulent pathogens such as these tend to impose strong selective pressures on their hosts driving the …

Optical Remote Sensing Of Oil Spills In The Gulf Of Mexico, Shaojie Sun

USF Tampa Graduate Theses and Dissertations

Assessment of oil spills in the ocean using passive remote sensing (i.e., reflected sun light) faces two challenges: detect oil presence/absence and quantify oil volume. While the optical properties of oil allow it to be differentiated from the surrounding marine environment, sun glint can facilitate oil presence/absence detection because the oil-water spatial contrast is enhanced due to wave dampening. However, sun glint also modulates the magnitude and shape of the spectral reflectance of surface oil. In addition to this difficulty, the most critical challenge is how to quantify oil volume (or thickness) through remote sensing. To date, such quantifications have …

Rats Fed Dietary Bioactive Components (Resistant Starch, Whole Grains, And Fat) Undergo Altered Biometrics And Gene Expression As A Result Of Gut Fermentation, Justin Lamont Guice

LSU Doctoral Dissertations

The whole grain and fat content of the diet have been previously shown to affect intestinal fermentation and phenotype conferred by high–amylose maize resistant starch (HAMRS), a form of fermentable dietary fiber. The current studies were designed to compare rodent gut health following consumption of whole grain and non–whole grain prebiotics on moderate fat (MF) and high fat (HF) diets, and to optimize health effect based on dosage of whole grain resistant starch prebiotics.

Study 1: Diets were prepared to contain the following factors RS (Present/Absent), WG (Present/Absent), and Fat (HF/MF). A three–way ANOVA was performed with statistical slice …

Rate-Determining Step And Active Sites Probing For Platinum-Group-Metal Free Cathode Catalyst In Fuel Cell, Yechuan Chen

Chemical and Biological Engineering ETDs

With the increasing demand on renewable energy, the fuel cell has attracted more and more interests because of its large power density and controllable size. However, the insufficiency of element abundance and unstable expensive price of conventional platinum-based electrocatalysts used in anode and cathode makes it essential to find their substitutes. As one of the most promising candidates to be used in cathode for oxygen reduction reaction (ORR), iron-nitrogen-carbon (Fe-N-C) catalysts have been widely investigated and get commercialized recently, but still lacks comprehensive understanding on the kinetic mechanism.

This dissertation has been divided into three parts with a discussion on …

The Impact Of The Concepts Of 'Common Good', 'Justice' And 'Diversity' In The Natural Law Of Our Time, Gines Marco

Journal of Vincentian Social Action

In this article we have projected three central objectives: first, to delimit the scope and limits of the recognition granted by the Aristotelian-Thomist tradition to the centrality of the common political good in life and in the fullness of the human being; Secondly, to specify the nature of the present difficulties that has the same possibility of the common reaches, by virtue of the valuation of the diversity projected by the liberal tradition inherited from Modernity; Thirdly, to analyze the impact that the dichotomy common good/diversity has had and continues to have on the way in which intra-organizational conflicts and …

Barriers To Pursuing Stem-Related Careers: Perceptions Of Hispanic Girls Enrolled In Advanced High School Stem Courses, Veronica Vijil, Julie P. Combs, Rebecca M. Bustamante

School Leadership Review

Researchers indicate that the United States has fallen behind other nations in science, technology, engineering, and mathematics (STEM) education (President's Council of Advisors on Science and Technology, 2010, 2012). A declining interest in the field of engineering as demonstrated by students who pursue degrees in STEM fields also threatens the U.S. competitive edge (National Science Foundation, 2013; Schneider, Judy, & Mazuca, 2012). Although some students perform successfully in STEM courses, an achievement gap between school-aged boys and girls is well-documented in the literature (e.g., College Board, 2007). Moreover, Hispanic students are underrepresented in science-related courses and careers (Hanley & Noblit, …

Dealing With Depression In Marriage, Jaelynn R. Jenkins, Alan Springer, Stephen F. Duncan

Forever Families

With an estimated 17 million Americans suffering from a depressive illness13, it is safe to say that mental illness is one of the most painful and persistent trials that a family will face8. The American Medical Association considers it the most incapacitating of chronic conditions in relation to social functioning12. More than one in ten people will suffer a serious depression at some point in their life; however nearly two-thirds do not get the help they need9, 13.

Making The Case For Marriage, Jennifer Crockett, Marissa Beebe, Stephen F. Duncan

Forever Families

In a recent report from the National Marriage Project, scholars David Popenoe and Barbara Dafoe Whitehead wrote, "Marriage is a fundamental social institution. It is central to the nurture and raising of children. It is the ‘social glue’ that reliably attaches fathers to children. It contributes to the physical, emotional and economic health of men, women and children, and thus to the nation as a whole. It is also one of the most highly prized of all human relationships and a central life goal of most Americans."

Increasing Intimacy In Marriage, Derek Willis Hagey, Amber L. Brewer, Rachel V. Jamieson, Robert F. Stahmann, Stephen F. Duncan

Forever Families

Intimacy is the closeness of your relationship with your spouse -- emotionally, spiritually, intellectually, sexually, and in many other ways. Intimacy is not an end goal but rather a journey that lasts throughout your marriage. Marriage and family researchers Schaefer and Olson4 describe attaining intimacy as "a process that occurs over time and is never completed or fully accomplished" (p. 50). As you both grow and develop, each of you changes. If you neglect intimacy in your marriage, you will grow apart. The time to work on intimacy is now.
