An Investigation Of Fraxinus Americana Branch Sway Using A 3 Dimensional Motion Capture System, Anna T. Campiformio

Master's Theses

Abstract

Wind is a dominant abiotic factor that a tree experiences throughout its lifetime and can cause severe tree damage, resulting in risk of injury to humans, and economic and ecological losses. It is thought that trees develop structural properties and architectures that help withstand loading conditions by dissipating wind energy through damping mechanisms. The role of branch motion in reducing potential dangerous wind loads has been the focus of relatively few studies. Even fewer studies have examined tree sway response to natural wind loaded conditions. In this investigation, branch frequencies were calculated for three Fraxinus americana using a three-dimensional …

Bivariate Drought Analysis Using Entropy Theory, Zengchao Hao, Vijay P. Singh

2011 Symposium on Data-Driven Approaches to Droughts

Drought duration and severity are two properties that are usually needed for drought analysis. To characterize the correlation between the two drought properties, a bivariate distribution is needed. A new method based on entropy theory is proposed for constructing the bivariate distribution that is capable of modeling drought duration and severity with different marginal distributions. Parameters of the joint distribution are estimated with Newton’s method. Monthly streamflow data from Brazos River at Waco, Texas, are employed to illustrate the application of the proposed method to model drought duration and severity for drought analysis.

Bivariate Drought Analysis Using Entropy Theory, Zengchao Hao, Vijay P. Singh

2011 Symposium on Data-Driven Approaches to Droughts

Drought analysis is important for water resources planning and management. Drought duration and severity are two main characteristics that have often been used for drought analysis, which can be defined using run theory with hydrological variables (e. g., streamflow).

A traditional way to characterize the drought duration or severity is based on fitting a probability density function. The drought duration can be modeled by a geometric distribution (discrete) or an exponential distribution (continuous). The gamma distribution is generally used to model drought severity.

Bivariate drought analysis is often needed to characterize the correlation between drought duration and severity. This article …

Spatial Patterns Of Herbaceous And Woody Recruitment In A Recently Restored Mixed Tidal Regime Freshwater Wetland, James B. Deemy

Theses and Dissertations

Ecological restoration of a converted wetland was characterized within a recently drained impoundment along the James River in Charles City County, Virginia. Colonizing vegetation was assessed over three growing seasons in both tidal and non-tidal environments. Study objectives were to (1) examine geospatial relations of recruitment patterns among colonizing species over three growing seasons, (2) quantify species composition and potential differences between extant species cover and soil seed banks across restored and natural wetland habitats and (3) assess geospatial patterns to develop a GIS model of bald cypress (Taxodium distichum L.) recruitment. The two most common native colonizing species during …

Locking Down The N-Terminus Of Prmt1 In Order To Assess The Role Of Motion In Activity, Taylor James Rasmussen

Undergraduate Honors Capstone Projects

Protein arginine methyltransferases (PRMTs) are involved In many major biological pathways in the human body. Processes that demonstrate arginine methylation by PRMTs include, but are not limited to, histone modification, DNA transcription, and post-translational protein modifications. Although recent research has allowed the identification of several PRMT isoforms and exposed their involvement in these processes, relatively little is known about the details of how these enzymes perform their biochemical duties. It is currently hypothesized that the N-terminus of PRMT variant I is involved in recognizing substrates and aiding in catalysis by virtue of a change in its conformation. To understand how …

Mapping Women's Movement In Medieval England, Claire Clement

Theses and Dissertations

This thesis investigates women’s geographical movement in medieval England from the perspective of mobility and freedom. It uses pilgrimage accounts from medieval miracle story collections and to gather information about individual travel patterns. The study uses GIS to analyze gendered mobility patterns, and to investigate whether there were noticeable differences in the distance which men and women traveled and the geographical area of the country they originated. It also analyzes the nearness of men’s and women’s respective origin towns to alternative pilgrimage locations, as a means of examining the factors determining gendered travel mobility. The study finds that women’s travel …

Surface Mass Transfer In Large Eddy Simulation (Les) Of Langmuir Turbulence, Cigdem Akan

USF Tampa Graduate Theses and Dissertations

Over the past century the study of gas exchange rates between the atmosphere and the ocean has received increased attention because of concern about the fate of greenhouse gases such as CO₂ released into the atmosphere. Of interest is the oceanic uptake of CO₂ in shallow water coastal regions as biological productivity in these regions is on average about three times larger than in the open ocean. It is well-known that in the absence of breaking surface waves, the water side turbulence controls gas transfer of sparingly soluble gases such as CO₂ from the air to the …

The Ecological Role Of Rhizophytic Green Algae In Soft-Bottom Habitats, Laura Bedinger

USF Tampa Graduate Theses and Dissertations

Rhizophytic algae are large, abundant primary producers throughout tropical and subtropical areas worldwide where they grow as an understory in seagrass beds, as well as form mixed or monospecific beds of exclusively rhizophytic algal species. In this dissertation, "rhizophytic algae" refers to coenocytic green algae (Chlorophyta) in the order Bryopsidales that use a net of rhizoids to anchor in unconsolidated sediments. In the development of seagrass beds, rhizophytic algae colonize bare patches and are thought to facilitate seagrass colonization by stabilizing sediments and providing organic matter. However, despite their prominence little is known about many aspects of the ecology of …

The Effects Of Modulating Enos Activity And Coupling On Leukocyte-Endothelial Interactions In Rat Mesenteric Postcapillary Venules, Amber N. Koon, Maria Kern, Lindon H. Young Phd, Brian Rueter, Edward S. Iames, Qian Chen Phd

Research Day

Background: Leukocyte-endothelial interactions associated with vascular injury are attenuated by endothelial-derived nitric oxide (NO). Endothelial NO synthase (eNOS) in the presence of tetrahydrobiopterin (BH4) produces NO from L-arginine and is termed eNOS coupling. However, when the ratio of dihydrobiopterin (BH2) to BH4 is increased, eNOS becomes uncoupled and produces superoxide instead of NO. Protein kinase C epsilon (PKC ε) positively regulates eNOS activity. This study examined modulating eNOS activity and coupling by superfusing BH2 (100 μM) by itself, combined with PKC ε activator (10μM) or PKC ε inhibitor, or combined with BH4 (100μM) and PKC ε activator in rat …

Imp2 Expression In The Mouse Nervous System, Sarah E. Chmielewski, Paige E. Black, Tiffany M. Holmes, Kelly S. Lau, Gary J. Bassell

Research Day

Background: Insulin-like growth factor-II (IGF-II) mRNA-binding protein-2 (IMP2) is one of the three homologs (IMP1-3) that play important roles in the posttranscriptional regulation of gene expression in several tissues. IMP1/ZBP1 (zipcode binding protein) has been shown to play important roles in axon guidance and regeneration by regulating the localization and translation of specific mRNAs. However, the function of IMP2 is least understood, largely because an isoform-specific antibody is not available, which makes the conventional techniques to locate protein expression not feasible.

Effects Of Nadph Oxidase Inhibitor Apocynin On Real-Time Blood Hydrogen Peroxide Release In Femoral Artery/Vein Ischemia And Reperfusion, C Woodsworth Parker, Kyle D. Bartol, Kerry-Anne Perkins, Qian Chen Phd, Lindon H. Young Phd

Research Day

Background: Vascular endothelial dysfunction can initiate oxidative stress during ischemiaJreperfusion (IIR). Endothelial dysfunction is characterized by an increase in blood hydrogen peroxide (H20 ]) and a decrease in endothelial-derived nitric oxide (NO) bioavailability. Previous studies using Go 6983, a broad-spectrum protein kinase C inhibitor that can inhibit NADPH oxidase activity, has attenuated blood H20 ] levels during femoralliR in vivo. This study examines the effects of apocynin, a direct NADPH oxidase inhibitor, on real-time blood H20 ] levels in femoral I1R in vivo. H20 ] microsensors (100 Mm) were inserted into both femoral veins in anesthetized rats.

Intralocus Sexual Conflict, Ontogenetic Conflict And Color Evolution In The Ibiza Wall Lizard, Podarcis Pityusensis, Nathan B. Dappen

Open Access Dissertations

Selection on the same trait may differ between the sexes and among age groups as a result of sex- and age-specific strategies in reproduction and survival. Antagonistic selective pressures on traits shared between the sexes can lead to intralocus sexual conflict, which occurs when selection favors the expression of particular alleles in one sex, but disfavors the expression of those same alleles in the opposite sex. Similarly, antagonistic selection on traits shared among age groups, can lead to intralocus ontogenetic conflict, which occurs when selection favors the expression of particular alleles in one age group, but disfavors the expression of …

Coping With Homonegative Experiences Among Gay Men: Impacts On Mental Health, Psychological Well-Being, And Identity Growth, Seth T. Christman

Open Access Dissertations

While minority stress research increasingly show that high rates of homonegative experiences can contribute to negative mental health outcomes in gay men, less is known about the ways in which gay men cope with these experiences and their potential to experience positive outcomes such as well-being and identity growth. Understanding the strengths of gay men in coping with numerous, multi-faceted homonegative experiences is essential in creating an accurate understanding of gay men’s development and informing research, policy, and practice around gay men’s well-being and growth. This study seeks to describe the nature of gay men’s homonegative experiences, describe the coping …

Small Molecule Inhibition Of Cd40–Cd154 Co-Stimulatory Interaction, Lakshmi Ganesan

Open Access Dissertations

The CD40–CD154 protein-protein interaction (PPI) is an important tumor necrosis factor superfamily (TNFSF) interaction that mainly provides co-stimulatory signals to T-cells consequent to antigen presentation in adaptive immunity. Blockade of this PPI can cause immune unresponsiveness (anergy) and is, therefore, an important therapeutic target for immunosuppression. Following our recent discovery of the first small-molecule inhibitors of this PPI, the present work focuses on the identification of compounds with improved ligand efficiency and the confirmation of their activity in cell-based assays. Our best inhibitors identified to date are organic dyes that show low micro-molar activity in inhibiting CD40–CD154 binding and whose …

Evolutionary Ecology Of The Corallivorous Gastropod, Coralliophila Abbreviata: Implications For Imperiled Caribbean Corals, Lyza Johnston

Open Access Dissertations

As the resiliency of coral reefs is eroded by a variety of natural and anthropogenic stressors, corallivory is becoming an increasingly important factor affecting the structure and function of these important ecosystems. Yet, little is known about the mechanistic drivers of coral-corallivore dynamics in many regions, including the Caribbean. In this dissertation, I used an integrated approach to investigate the evolutionary ecology of the coral-eating gastropod, Coralliophila abbreviata, on the reefs of Florida and the Caribbean. Coralliophila abbreviata snails live and feed on most of the major reef-building corals in the region and cause substantial and chronic mortality of the …
