Remediation Of Roadway Runoff Nutrients: Querying Sources Delivery Mechanism, Efficacy Of Stormwater Best Management Practices, And Stormwater Routing Through Karst Geology, Mohammad Shokri

Electronic Theses and Dissertations, 2020-2023

Stormwater road runoff is a widespread non-point source of contaminants such as nutrients, which endangers water bodies, especially in vulnerable karst areas such as Florida. While roadside vegetated filter strips (VFSs) and stormwater basins are generally accepted best management practices (BMPs) for stormwater management, uncertainties about VFS nutrient removal are reported and stormwater basins are concerned of facilitating contaminant transport. In this dissertation, the application and efficacy of engineered infiltration media was tested as a subgrade for the enhanced nutrient removal from roadway runoff. Results of field-scale laboratory testing indicated that a VFS with engineered biosorption activated media (BAM) outperformed …

Incongruous Surrealism Within Narrative Animated Film, Daniel Mccabe Jan 2021

Incongruous Surrealism Within Narrative Animated Film, Daniel Mccabe

Electronic Theses and Dissertations, 2020-2023

A pop music video is a form of media containing incongruous surrealistic imagery with a narrative structure supplied by song lyrics. The lyrics' presence allows filmmakers to digress from sequential imagery through introduction of nonlinear visual elements. I will analyze these surrealist film elements through several post-modern philosophies to better understand how this animated audio-visual synthesis resides in the larger world of art theory and its relationship to the popular music video. This analysis coincides with the practical and theoretical experimentation evident in the film companion to this thesis, Slapper the Cat: A Musical Cartoon. A long-form animated music video …

Mechanics Of Low Dimensional Biomimetic Scale Metamaterials, Hossein Ebrahimi

Electronic Theses and Dissertations, 2020-2023

Combination of topology and material could play an important role in giving rise to nontraditional behavior in mechanical structures and is a typical strategy in nature. Topology is concerned with the geometrical and spatial properties of the objects, which are preserved under continues mechanical deformation of the object such as stretching, bending, twisting, etc. In this work, we focus on structures based on fish scale inspired surface topology. The utilized idea for surface topology is a bioinspired design on the substrate of biological scale-covered systems. Scales are a path breaking evolutionary adaptation that accompanied vertebrate evolution for the past 500 …

Diffusion Biomarkers To Characterize Tissue Microstructure In Chronic Myocardial Infarction, Mohammad Tanjib Rahman Jan 2021

Diffusion Biomarkers To Characterize Tissue Microstructure In Chronic Myocardial Infarction, Mohammad Tanjib Rahman

Electronic Theses and Dissertations, 2020-2023

Non-invasive imaging techniques to detect and characterize infarcted myocardium are critical for myocardial infarction (MI) prognosis and post-MI risk assessment. Many existing imaging techniques (such as T1-mapping) for MI detection require the use of contrast agents, which are not recommended for patients with renal failure. Cardiac diffusion tensor magnetic resonance imaging (cDTI), a non-contrast imaging technique, allows estimating the aggregate cardiomyocyte microstructure in healthy subjects and its remodeling as a result of cardiac diseases. Two main questions are investigated in this thesis: 1) how cDTI based biomarkers can characterize microstructural changes occurring post-MI; and 2) if cDTI based biomarkers can …

The Language Of Personas: Poetic Masks In Confessional And Black Arts Poems, Grecia Espinoza Jan 2021

The Language Of Personas: Poetic Masks In Confessional And Black Arts Poems, Grecia Espinoza

Honors Undergraduate Theses

This thesis considers Confessional poetry and Black Arts poetry against the backdrop of the political and social culture of the 1950s that influenced the styles of these two major poetic movements. I examine Sylvia Plath's and Nikki Giovanni's distinct poetic personas and the language they employ in relation to each other as representatives of confessional and Black Arts poetry, two poetic styles often thought to be inherently opposed to each other, one personal and one political. I identify connections between these seemingly different poets and movements through close readings of key poems by Plath and Giovanni that situates them within …

Systemic Inequalities For Afro-Brazilians, Teya De Oliveira Jan 2021

Systemic Inequalities For Afro-Brazilians, Teya De Oliveira

Honors Undergraduate Theses

Brazil is commonly viewed as a racial paradise on the world front due to its highly mixed-race population. Compared to the United States and South Africa, race-based discriminatory laws and racially motivated violence in Brazil have been absent. Despite these factors, African descendants in Brazil have been at a socioeconomic disadvantage since the nation's birth. Brazilian anthropologist Gilberto Freyre put forth the racial democracy ideology, stating that anyone can ascend the socioeconomic ladder no matter their race. This thesis opposes the racial democracy theory by exposing the various aspects in which Afro-Brazilians are systemically oppressed. In education, jobs & wages, …

An Anthropological Analysis Of Ancient, Historic, And Modern Anatolian Cities, Genevieve S. Hall Jan 2021

An Anthropological Analysis Of Ancient, Historic, And Modern Anatolian Cities, Genevieve S. Hall

Honors Undergraduate Theses

This thesis proposes a model for the comparison of cities as settlement patterns, based primarily on the works of Monica Smith, Michael E. Smith, and V. Gordon Childe. The Tripart Stage-Based Model proposed here examines city proportions, internal specialization, and external specialization, as well as variables within each characteristic. It is intended for use in both the individual study of a settlement's form and function as well as comparative analysis. The Tripart Stage-Based Model operationalizes Monica Smith's triaxial model and creates a progression of analysis beginning with the form of the city before moving through its individual and larger context. …

Combat Music, Usability, And Presence In Video Games, Jedidah Wong Jan 2021

Combat Music, Usability, And Presence In Video Games, Jedidah Wong

Honors Undergraduate Theses

The interactive nature of video games offers players unique playthroughs of the same game. Choices made during gameplay, despite going through the same narrative story, create a journey that differs from other players. Music can help support a player's connection to the game's characters and narrative while also providing information to the player to guide their decisions. Ludomusicological studies in the past have shown how music can support a game's narrative, while also serving to inform players of changes in game states. The usability function of music, while crucial in this overall sonic experience, is not the sole purpose that …

Stable Isotope Analysis Of An Invasive Crab Species, Charybdis Hellerii, In The Indian River Lagoon, Justin R. Meyer Jan 2021

Stable Isotope Analysis Of An Invasive Crab Species, Charybdis Hellerii, In The Indian River Lagoon, Justin R. Meyer

Honors Undergraduate Theses

The world has never been more connected than it is today. While this is true for people, it is also true for Earth's flora and fauna. Unfortunately, this connectedness has contributed to unprecedented invasive species introductions around the world. Most introductions result in an introduced species dying out in the newly invaded territory and never becoming established. Other introduced species establish and persist for years, but never have a noticeable effect on local ecosystems. However, occasionally, an invasive species gets introduced to a new area and has negative impacts on native plant and animal life. The Indo-Pacific swimming crab, Charybdis …

Strategies For Successful Mangrove Living Shoreline Stabilizations In Shallow Water Subtropical Estuaries, Rebecca Fillyaw

Electronic Theses and Dissertations, 2020-2023

Mangrove living shorelines are an effective alternative to hard-armoring, which combat erosion while also increasing habitat. To improve the success of future mangrove deployments, an experimental Rhizophora mangle living shoreline was deployed within Mosquito Lagoon, FL. A factorial design was used to test the impact of mangrove age, breakwater presence, and mangrove placement on mangrove survival and growth. Environmental factors were monitored to isolate the reason for mangrove mortalities. Mangrove age was represented by 3 developmental stages: "seedlings" at 11-months-old, "transitionals" at 23-months-old, and "adults" between 35 and 47-months-old. Mixed mangrove age groups were included to identify if seedling survival …

Sex Differences In Peripheral Fat Detection And Metabolism, Naima Dahir Jan 2021

Sex Differences In Peripheral Fat Detection And Metabolism, Naima Dahir

Electronic Theses and Dissertations, 2020-2023

The current epidemic of obesity is driven, at least in part, by excessive caloric intake and fat intake has been implicated as a major contributing factor. The mammalian taste system displays marked plasticity, and it has been shown that the detection of fatty acids, the prototypical fat taste stimulus, leads to reduced sensitivity upon prolonged exposure to a high-fat diet. Increased obesity and metabolic disorders in postmenopausal females indicate that the female steroid hormone, estrogen, may contribute to metabolic homeostasis. Sex differences in the taste system were explored using a multidisciplinary approach to examine the ways in which estrogen influences …

Plasmonic Properties Of Nanopatterned Graphene, Muhammad Waqas Shabbir Jan 2021

Plasmonic Properties Of Nanopatterned Graphene, Muhammad Waqas Shabbir

Electronic Theses and Dissertations, 2020-2023

Graphene is an atomically thin two-dimensional material with carbon atoms arranged in a honeycomb lattice. It has been successfully mechanically exfoliated from graphite and characterized in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester, UK. While suspended graphene holds the world record in mobility exceeding 100,000 cm2/Vs, which means that graphene could increase the operating frequency of electronic devices up to the THz regime. For example, imaging computer chips running at a few THz frequency, which would be about 1000 times faster than current chips. However, there are two main obstacles for using graphene in electronics …

Anti-Map Triple Therapy Supports Immunomodulatory Therapeutic Response In Crohn's Disease Through Downregulation Of Nf-Kb Activation In The Absence Of Map Detection, Erij Elkamel

Electronic Theses and Dissertations, 2020-2023

The triple antibiotic formulation, known as anti-MAP therapy, exhibits unique synergistic antimicrobial activity and should be effective for treatment of Crohn's disease (CD) associated with Mycobacterium avium subspecies paratuberculosis (MAP). The absence of MAP detection in some CD cases may be linked to poor diagnostics or lack of association with the disease. To understand the therapeutic response of some CD patients to anti-MAP therapy in absence of MAP detection, the immunomodulatory potency of anti-MAP therapy and its major ingredients, clarithromycin (CLA) and rifabutin (RIF), in THP-1, Caco-2, and Jurkat T-cells were investigated. Anti-MAP formulation at 2.0 µg/mL decreased MAP viability …

A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones Jan 2021

A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones

Electronic Theses and Dissertations, 2020-2023

The effects of roads, buildings, and cities on animal populations are widespread and, often times, disastrous. These structures fragment animals' homes, inhibiting their ability to obtain essential resources and to reproduce. The question arises then: Under what circumstances can an animal population persist in a fragmented landscape? To attempt to answer this question, we present a spatially explicit reaction-diffusion model with varying growth and diffusion rates that incorporates animal behavior at points where habitats are fragmented for four different habitats. The outcome of extinction or persistence of the animal population is determined by examining the effects of changing parameters on …

Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume Jan 2021

Reassessing The Transcriptional Regulation Of Protective Cd4 T Cell Responses Against Influenza A Virus, Kunal Dhume

Electronic Theses and Dissertations, 2020-2023

An attractive strategy to improve efficacy of current Influenza A Virus (IAV) vaccines is to promote protective CD4 T cell responses. Antiviral CD4 T cell responses are predominantly classified as strong IFN-gamma producing T helper type 1 (Th1) cells. Yet, the role of IFN-gamma in protection against IAV is still unclear, suggesting absolute Th1 polarization may be expendable for effective IAV immunity. Here we test this hypothesis using models that restrict the deficiency of known transcriptional regulators of Th1 immunity in only CD4 T cells, avoiding indirect impact on other immune cell responses. We find the 'master regulator' of Th1 …
