Vascular Calcification In A Mouse Model Of Chronic Kidney Disease And In Human Peripheral Arterial Disease, Breanna Pederson

Theses and Dissertations

Vascular calcification is a process in which calcium and phosphate crystallize to form hydroxyapatite in the extracellular matrix of blood vessels. There are two forms of arterial calcification: intimal and medial, which occur via different etiologies. Intimal calcification is associated with atherosclerosis and occurs in the layer of endothelial cells adjacent to the artery lumen. Medial arterial calcification (MAC) is independent of atherosclerosis and occurs in the middle, muscular layer of the artery. MAC is strongly associated with aging, diabetes mellitus, and chronic kidney disease (CKD). MAC is frequently in patients with peripheral arterial disease (PAD). Most studies to date …

Mechanics Based Characterization Of Elastic Metamaterials, Mamdudur Rahman

Theses and Dissertations

In bandgap engineering there is a shortage of systematic design approach which enables one to select design variables to achieve bandgap in desired frequency range. Tools that can address this can open new areas of interest, especially since phononic crystals with low frequency bandgaps have multitude of applications in attenuation of structural vibration. Furthermore, mechanics-based characterization of phononic crystals had not seen much progress in the recent years while a lot of applied research had been conducted on phononic materials with material phase periodicity and other factors taken into consideration. This work aims to propose a systematic characterization approach of …

An Examination Of Civil Asset Forfeiture In South Carolina, Jeffrey Trowbridge

Theses and Dissertations

Civil asset forfeiture allows the government to seize and forfeit property that is associated with criminal activity without arresting or charging the property owner. Although expansive in its potential application, little is understood about the characteristics of civil asset forfeiture cases, the property owners involved in forfeiture cases, or the characteristics of any criminal cases pursued parallel to the civil cases. Utilizing open-source, public court records, this dissertation provides an exploratory analysis of these gaps in the literature by examining the types of civil asset forfeiture used, the value of asset forfeiture cases, how money from asset forfeiture is divided …

Some of my examination is done by means of direct consideration of such concepts and principles. And some of it is done by addressing such concepts and principles indirectly as I address questions about practical ethical or political concerns including: how can public officials make decisions that are not biased, what …

You're Not The Only One Who Can Teach Us: Teacher Facilitation In Three Secondary School Music Contexts, David Dwight Bowman

Theses and Dissertations

Over the last half-century, school music reforms have focused more on content than process, and the directive teaching that serves as the dominant method used by secondary school music teachers is not adequately meeting the needs of the students who currently occupy American high schools. To improve teaching practice in one such high school, an action research study was conducted to investigate the use of facilitative teaching strategies, how those teaching strategies impact students’ learning experience, and what the perceived impacts of those strategies are. A qualitative case study methodology was employed to determine how an intervention period of facilitative …

In Situ Assembly Enabling Adhesive-Free Bonding Of Large Area Electronic Sensors To Concrete For Structural Health Monitoring, Emmanuel Ogunniyi, Han Liu, Austin Downey, Simon Laflamme, Caroline Bennett, William Collins, Hongki Jo, Paul Ziehl

Faculty Publications

Cracks developed in concrete infrastructure are one of the primary mechanisms that degrade their structural integrity, which may result in structural failures. Previous research on soft elastomeric capacitors (SEC) has shown their viability for structural health monitoring of structural materials, including concrete, steel, and fiberglass composites. The SEC, or its derivative version with a corrugated geometry termed corrugated SEC or cSEC, is a parallel plate capacitor. Prior work demonstrated that it was possible to directly paint the electrode interfacing with the structural material onto the structure and adhere the rest of the pre-fabricated sensor onto the wet interface, thereby eliminating …

Allura Red Ac Is A Xenobiotic. Is It Also A Carcinogen?, Lorne J. Hofseth Ph.D., James Hébert Scd, Elizabeth Angela Murphy, Erica Trauner, Athul Vikas, Quinn Harris, Alexander A. Chumanevich

Faculty Publications

Merriam-Webster and Oxford define a xenobiotic as any substance foreign to living systems. Allura Red AC (a.k.a., E129; FD&C Red No. 40), a synthetic food dye extensively used in manufacturing ultra-processed foods and therefore highly prevalent in our food supply, falls under this category. The surge in synthetic food dye consumption during the 70s and 80s was followed by an epidemic of metabolic diseases and the emergence of early-onset colorectal cancer in the 1990s. This temporal association raises significant concerns, particularly given the widespread inclusion of synthetic food dyes in ultra-processed products, notably those marketed toward children. Given its interactions …

Regulation And Function Of The Rna-Binding Protein Khsrp During Neuronal Development, Regeneration And Axonal Injury Response, Courtney Nicole Buchanan

Theses and Dissertations

Axons, which extend long distances from neuronal cell bodies, rely on localized mRNA translation to swiftly respond to extracellular stimuli and physiological states. This work investigates the mechanism underlying the RNA-binding protein KHSRP’s, axonal mRNA translation and regulatory pathways involved in neuronal growth and regeneration. Our results indicate that KHSRP deletion in mice leads to upregulation of growth-associated mRNAs linked to neuronal morphology and function, resulting in increased axon growth and altered memory consolidation. Indicating a critical role for KHSRP in neuronal development and function through post-transcriptional regulation (Chapter 2). Additionally, we show there is a rapid increase in axonal …

From Colonial Frontier To A Slave Society: "Second Slavery" And The Former Backcountry Of South Carolina In The Early Republic, 1780-1833, Elisabeth Zoe Horecny

Theses and Dissertations

Although the South Carolina backcountry was labeled pre-modern by contemporaries and, later, by some historians, it was the model of a modern, “second slavery” in the Atlantic World as evidenced by cultural, economic, and political changes there to accommodate and promote the expansion of slavery. The former backcountry was exemplarily of “second slavery” because the region modernized to create a slave society, instead of modifying the existing colonial system of mass enslavement in the region. Enslaved people responded to these changes in the former backcountry by spreading their oral traditions in healing and religion, maintaining African traditions, and creating communities …

If We Only Had A Wheelbarrow: Asset-Based Pedagogy In The Elementary Classroom, Elizabeth Bedell

Theses and Dissertations

The challenges facing today’s educators are much and many. Among them ranks the persistent underachievement of students from racially and culturally diverse backgrounds. Attempts to remedy this have historically taken a deficit approach, one that attempts to “fix” students by melding them to the norms of the dominant culture, ultimately diminishing their cultural ways of knowing and being and perpetuating inequity. Although educators want to do better, most have simply not been provided with the professional learning that would support their centering students’ voices and experiences as essential to learning

With a focus on asset-based pedagogy, this convergent mixed methods …

Winning And Losing At The Federal District Courts, Madison Shanks

Theses and Dissertations

The federal criminal courts are unique compared to the rest of the justice system. Cases in these courts pit a government backed prosecutor with an informational and first-moving advantage, against an often-disadvantaged defendant in an adversarial system that ultimately determines who wins and who loses. This asymmetry in criminal cases at the federal district courts presents a situation in which we can understand how courtroom actors matter for the justice process, and specifically if and how attorneys’ strategies differ and ultimately influence outcomes for their clients. This dissertation project builds on an existing data collection project that captures motion filings …
