A Multi-Scale Analysis Of The Hartselle Sandstone To Characterize Reservoir Properties And Inform Carbon Sequestration Feasibility, Xiaotian Wang

Electronic Theses and Dissertations

This dissertation takes multiple approaches to investigate lithology, depositional environments, diagenesis, and reservoir quality for petroleum and carbon sequestration in the Mississippian Hartselle Sandstone. The Hartselle Sandstone has been considered economically important for its viscous bitumen and natural gas reserves, with only minor attention given to potential oil reserves due to its low permeability. I proposed to reinvestigate the possibility of oil production from the Hartselle Sandstone, including a focus on the required elements of a conventional petroleum system. A detailed petrographic analysis recognized three lithofacies associations: beach lithofacies association, protected transgressive wave-dominated coast association, and unprotected transgressive tidal flat …

Predicting Microstructure Evolution In Alloys Using Deep Learning, Benjamin Mullins Rhoads

Electronic Theses and Dissertations

Modeling the microstructure evolution and linking them to materials properties is critical in establishing processing-microstructure-property linkage in materials. In this project, the evolution of microstructure of Fe-C alloys is modeled using phase field simulations to understand the behavior of these alloys under various cooling temperatures and initial carbon concentrations. However, these simulations require significant computational resources. Therefore, in this thesis, a convolutional neural network (CNN) and gated recurrent unit (GRU) are coupled with phase field simulations to predict the solidification of Fe-C alloys. In addition to the data-driven approach, the solid-liquid interfacial energy is incorporated during the training process, giving …

Design, Synthesis, And Application Of Indolizine-Donor Containing Fluorophores For Near-Infrared And Shortwave-Infrared Biological Imaging, William E. Meador

Electronic Theses and Dissertations

Low energy light in the near infrared (NIR, 700 – 1000 nm), shortwave infrared (SWIR, 1000 – 1700 nm), and extended SWIR (ESWIR, 1700 – 2700 nm) has numerous important applications including fluorescence biological imaging, secure display technologies, and photodetectors. While inorganic materials have dominated each of these spectral regions, organic molecules that absorb and emit light in these regions are being heavily researched due to their high degree of molecular tunability via structure-function relationships, cheap production due to the avoidance of precious metals, ease of manufacturing through solution processability, and operation under physiological and ambient conditions. This dissertation illustrates …

On The Tensor Product Of Archimedean Riesz Spaces, Page Thorn

Electronic Theses and Dissertations

We characterize when, for any infinite cardinal α, Fremlin’s Archimedean Riesz space tensor product of two Archimedean Riesz spaces is Dedekind α-complete. We provide an example of an ideal I in an Archimedean Riesz space E such that the Fremlin tensor product of I with itself is not an ideal in the Fremlin tensor product of E with itself. On the other hand, we present conditions for which the Fremlin tensor product of ideals is an ideal and that the Fremlin tensor product of projection bands is a projection band.

Lastly, we prove that the Carathéodory space of place functions …

It’S Just A Way Of Life: A Symbolic-Interactionist Approach To Inequalities In The Contemporary American South, Angela Rankin

Electronic Theses and Dissertations

The contemporary American South is characterized by significant inequalities that are deeply- embedded into the social fabric of the region. These inequalities are dictated by cultural and social dynamics that have shaped the Southern region over time; however, they are reinforced daily through the individual agency of Southern social actors. This thesis aims to analyze Southern inequalities through a symbolic-interactionist focused lens and data collected from semi-structured, qualitative interviews conducted with over 70 White Southerners in two places within the American South- Oxford, MS, and Memphis, TN. In this thesis, I argue that White Southern actors actively use their individual …

“The War Will Be Over Sometime”: Female Authorship, Time, Trauma, And Healing In H.D.’S Wartime Works, Loren Samons

Electronic Theses and Dissertations

As a tripartite collection of poems, at first glance H.D.'s Trilogy appears vastly different from her semi-autobiographical novel, Bid Me to Live, but the two are not as removed from each other as their formats and publication timelines might indicate. In fact, their connectedness is much less discreet than many scholars have suggested. In addition to being thematically similar in terms of their considerations of time and gender, Bid Me to Live and Trilogy could be viewed as works in conversation with each other, reflecting the development of the female authorial voice along a timeline of war-related trauma progression and …

Novel Formulation Strategies For Oral And Ocular Drug Delivery, Samir Senapati

Electronic Theses and Dissertations

Nanoformulations such as nanoemulsions (NE), solid lipid nanoparticles (SLN), and nanostructured lipid carriers (NLCs) are colloidal particulate systems in the submicron size range and act as carriers of drug molecules. Their size varies from 10 to 1,000 nm (1). The capacity of these nanoparticles to permeate through many anatomical barriers, the prolonged release of their contents, and their stability on the nanometer scale have widely contributed to their efficacy in drug delivery. Owing to the advantages of nanoformulations, they were further explored in our studies to target different diseases like Dry eye disease (DED), glaucoma, and malaria.

Oh Men Of Justice! Petitioning In Protectorate Bahrain 1919-1939, Ashleen Williams

Electronic Theses and Dissertations

In 1934, Bahraini petitioners wrote to the Ruler of Bahrain to demand protection for the rights of individuals. The petition was not the first, nor was it the last, to demand rights in Bahrain during the interwar period. This study examines petitioning and claim-making in protectorate Bahrain. A close reading of petitions submitted by different Bahrain communities from 1919 to 1939 demonstrates Bahrain was shaped by multiple competing and cooperating priorities. This study identifies three stages of petitioning in the interwar period: petitioning for protection, petition for rights, and nationalist petitioning. Using a framework of jurisdictional ambiguity, the dissertation shows …

Tidally-Induced Nonlinear Resonances In Extreme Mass Ratio Inspirals With An Analogue Model, David Bronicki

Electronic Theses and Dissertations

The future space-based gravitational wave observatory LISA is expected to capture signals from extreme mass ratio inspirals (EMRIs), a new class of inspiral systems which current detectors are not sensitive to. Detection and characterization of EMRI systems requires long and accurate waveform models, which may require accounting for effects like those seen in the presence of an external tidal field. In particular, such a perturbation may break integrability of the system and cause significant dephasing. In this thesis, we use a Newtonian analogue of a Kerr black hole to study the effect of an external tidal field when the system …

Different Phonographic L1 Effects In Processing L2 Chinese Characters: The Role Of Phonology And Orthography In Lexical Entry, Shuang Cheng

Electronic Theses and Dissertations

Orthography-phonology mapping in world languages exhibits variations. Extensive research has investigated whether orthographic-phonological consistency impacts the cognitive processing of written words. A major body of work has focused on the recognition of phonographic first language (L1) written words. Results show that the more transparent the orthography, the more reliance on phonological processing, and vice versa (Katz & Frost, 1992). Another body of work has paid attention to the cognitive process of identifying Chinese characters because of their logographic nature. These studies have mostly focused on recognizing L1 Chinese words (including both simplified and traditional written words) (Perfetti & Zhang, 1995; …
