Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon Jan 2021

Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon

Electronic Theses and Dissertations

Chronic hyperglycemia is one of the main characteristics of type 2 diabetes mellitus (T2DM). With the increased prevalence of T2DM, the risk of cardiovascular complications, including heart attack or stroke, is increased. Complications linked to the vasculature are increased vascular calcification (VC) or mineral deposition within the medial layer of conducting arteries. Under calcification conditions, vascular smooth muscle cells (VSMCs) undergo an osteogenic switch to an osteoblast-like cell and begin producing bone proteins. Chronic hyperglycemia can also result in increased extracellular matrix (ECM) synthesis, accumulation, and crosslinking. One of the cell types responsible for increased ECM synthesis are ‘activated’ fibroblasts …

The Value Of Participating In Cooperative Education, Megan Upchurch Miller

Electronic Theses and Dissertations

The benefits of experiential education are well known and a popular discussion topic on college campuses. The value of participation in a co-op work experience is recognized by employers, but not necessarily by the students they are hoping to hire. This study sought to determine whether or not students who did participate in a co-op found their experiences to be beneficial to their personal or professional growth.


Constructing And Validating Feature Models Using Relational, Document, And Graph Databases, Hazim Shatnawi Jan 2021

Constructing And Validating Feature Models Using Relational, Document, And Graph Databases, Hazim Shatnawi

Electronic Theses and Dissertations

Building a software product line (SPL) is a systematic strategy for reusing software within a family of related systems from some application domain. To define an SPL, a domain analyst must identify the common and variable aspects of a family of systems and capture them for later use in construction of specific products. To do so, Feature-Oriented Domain Analysis (FODA) introduced the feature model as an abstraction to represent the common and variable aspects, using a feature diagram to depict the model visually. However, this abstraction is often difficult for developers to use because most tools rely on specialized theories, …

Enhanced Electrochemical And Light-Driven Co2 Reduction By Incoporating Pendant Functionality In The Second-Coordination Sphere Of Molecular Catalysts, Sayontani Sinha Roy

Electronic Theses and Dissertations

With the increase in global population and rapid industrialization, a gigantic amount of greenhouse gases is being released into the atmosphere each year. The catastrophic effect of these accumulated greenhouse gases is driving global climate change and adversely impacting our ecosystem. Popularizing the traditional renewable energy sources (such as solar and wind energy) can mitigate the problem by cutting down anthropogenic CO2 emissions, which is the major contributor to this global problem. However, the intermittent nature of these energy sources is problematic to reliably power society throughout the year. Therefore, converting CO2 to various value-added chemicals with the aid of …


From Goethe To Godel: Against The Language Of Thought Hypothesis, Berit Turnquist Jan 2021

From Goethe To Godel: Against The Language Of Thought Hypothesis, Berit Turnquist

Electronic Theses and Dissertations

This paper re-examines the language of thought hypothesis by considering objections raised by Johann Wolfgang von Goethe against influential views about the relation of language and thought in the late 18th and early 19th centuries, such as those posited by Herder, Schleiermacher, Schlegel, and von Humboldt. Goethe’s Theory of Colors contains an instructive critique of the idea held by many of his contemporaries: that the bounds and limits of thought are linguistic in character. I argue that Goethe’s remarks anticipate later 20th-century challenges to the language of thought hypothesis regarding implicit cognition, such as Dennett’s “chess playing” example, as well …

As the Flagship university in Mississippi, UM has a …


Dynamic Characterization Of Bio-Inspired Functionally Graded Polymer Infused Metallic Foams For Blast And Impact Hazard Mitigation, Damian Stoddard Jan 2021

Dynamic Characterization Of Bio-Inspired Functionally Graded Polymer Infused Metallic Foams For Blast And Impact Hazard Mitigation, Damian Stoddard

Electronic Theses and Dissertations

Current vehicular crashworthy systems and body armor designs are effective in protecting personnel and equipment from disaster due to their energy absorbing characteristics. However, little is understood about how to replicate naturally occurring designs through man-made techniques, and the role of functional grading to further improve the performance of such protective systems. This research investigates an advanced material system analogous to a bio-inspired functionally graded material that will serve as a protective system for the mitigation of dynamic events such as low-velocity impact and/or blast loading.


A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do Jan 2021

A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do

Electronic Theses and Dissertations

The Heisenberg Hamiltonian is the prototype model for quantum magnetism. The Hamilto- nian includes exchange couplings between vector spins, which are the intrinsic magnetic moments of localized electrons. The classical energy between any pair of interacting spins can be minimized by aligning them parallel (ferromagnetic case) or antiparallel (antiferromagnetic), depending on the sign of the coupling. But quantum fluctuations play a key role, and a full quantum mechanical treatment of the many-body system is generally required. Finding the exact ground-state energy and wave function of isotropic antiferromagnetic (AFM) systems for an arbitrary spin-S and lattice morphology is still a challenging …

Search For Cpt And Lorentz Invariance Violation In The Muon G-2 Experiment At Fermilab, Meghna Bhattacharya Jan 2021

Search For Cpt And Lorentz Invariance Violation In The Muon G-2 Experiment At Fermilab, Meghna Bhattacharya

Electronic Theses and Dissertations

The Muon g-2 experiment at Fermilab (E989) aims to measure the anomalous magnetic moment of the muon, $a_{\mu}= (g-2)/2$, to a groundbreaking precision of $140$ ppb, obtaining a near four-fold increase in precision over the previous experiment, E821, at the Brookhaven National Laboratory (BNL). The value of $a_{\mu}$ from BNL currently differs from the Standard Model prediction by $\sim 3.7$ standard deviations, suggesting the potential for new physics and therefore, motivating a new experiment.Because the theory predicts this number with high precision, testing the g-factor through experiment provides a stringent test of the SM and can suggest physics beyond the …

Designing For Democracy: How Democratizing States Design International Organizations, Marissa Wyant Jan 2021

Designing For Democracy: How Democratizing States Design International Organizations, Marissa Wyant

Electronic Theses and Dissertations

Building on work by Paul Poast and Johannes Urpelainen that suggests that democratizing states are more likely to form new international governmental organizations rather than join existing ones, I ask the question: how do these states design the organizations they form, and how do those design choices compare to the choices made by consolidated democracies and by nondemocracies? I focus on three design choices made by states regarding membership constraints, voting procedures, and dispute resolution processes. By comparing and analyzing founding charters, I find that democratizing states were more likely to constrain access to membership into these organizations to regional …


Microbial Community Responses To Salinification: Applications In Climate Change And Extreme Environments, Eric Weingarten Jan 2021

Microbial Community Responses To Salinification: Applications In Climate Change And Extreme Environments, Eric Weingarten

Electronic Theses and Dissertations

Sediment microbial community responses to elevated salinity are important in predicting the effects of sea level rise as well as in understanding those communities that can thrive in extreme environments. In this dissertation, I use natural and field experiments to investigate how salinity influences microbiome structure in coastal wetlands. Through the use of amplicon sequencing, I demonstrate that there are compositional differences between the microbiota of four wetland salinity classes: limnetic, oligohaline, mesohaline, and polyhaline. These results were reciprocated in a microcosm study exposing freshwater sediment to meso- and polyhaline conditions, showing that communities shifted proportionally to the magnitude of …
