Borophene And Graphene For Non-Enzymatic Biosensor- Ab-Initio Study, Omar A. Ismail
Borophene And Graphene For Non-Enzymatic Biosensor- Ab-Initio Study, Omar A. Ismail
Theses and Dissertations
Non-enzymatic glucose sensing holds promise to overcome limitations associated with glucose oxidase, such as oxygen dependence and short shelf life. This study explores the potential sensing capabilities of borophene and graphene through direct interaction with various compounds, including β-glucose, uric acid, ascorbic acid, fructose, and acetaminophen. Using Density Functional Theory (DFT), we calculated binding energies and the respective Density of States (DOS) for these adsorbates on both graphene and borophene surfaces. Preliminary results suggest that borophene might exhibit nearly twice the affinity for β-glucose compared to graphene. Moreover, the calculated Density of States reveals distinct distortions in the electronic states …

Harnessing The Power Of Student Voice: A Case Study Of Hybrid Proficiency-Based And Co-Created Curriculum And Assessment, Kaitlyn A. Seamons
Theses and Dissertations
Assessment has become a dirty word in arts education, because art is notoriously difficult to assess. Assessment, which is often disliked or even disavowed by arts educators, due to its history of incompatibility with the idiosyncratic nature of arts learning, should ideally be utilized as a means of measuring student progress and help teachers understand how to help students succeed. While assessment can also be used to evaluate programs and teachers and to compare student successes relative to those of other students, I will be focusing on measuring individual student progress for my thesis and building a curriculum to support …

Understanding The Origin, Evolution, And Dynamics Of Transneptunian Binaries, Benjamin C N Proudfoot
Theses and Dissertations
This dissertation discusses research that focuses on understanding transneptunian objects (TNOs) using a variety of techniques and approaches. In Chapter 1, I introduce the main concepts used throughout this dissertation and discuss the current understanding of the transneptunian region. In Chapter 2, I discuss my efforts to understand how Neptune's late stages of migration affect the Haumea family, the only known collisional family in the transneptunian region. Using advanced simulations of Neptune migration, I find that the Haumea family can plausibly form before the termination of giant planet migration and show that this extensively mixes the family. The simplest explanation …
Characterization Of Friction At The Tool/Material Interface In Friction Stir Welding, Bryan Gonzalo Ramos Gonzales
Characterization Of Friction At The Tool/Material Interface In Friction Stir Welding, Bryan Gonzalo Ramos Gonzales
Theses and Dissertations
Friction Stir Welding (FSW) process development is very costly, and it is still experimental. A predictive model would optimize the weld by changing parameters and obtaining results that reflect the physical process. Friction is the primary adjustable parameter in FSW modeling. Currently, friction model selection is not physic-based. It is based on what is available and contributes to the best fit between the model and experimental data. The research objective is to characterize the interface tool/base material by studying the effect of tool friction coefficient and thermal properties. This is accomplished by changing welding parameters such as force, rpm, and …

Simulating Government Institutions In Networked Societies, Michael Richards
Theses and Dissertations
Modern human societies give rise to the expression of complex group dynamics between the members of said society due to the abundance of continued interactions. Of particular interest are how institutions affect these interactions between societal members, alter the resulting group dynamics, and impact society as a whole through their rules. Simulating these dynamics allows for greater insight into how these institutions function and allows researchers to pose interesting questions and test hypotheses within a laboratory setting. We present a novel approach to simulating institutions, particularly governments, within a networked society. This approach builds upon the Junior High Game, which …
Local Atomic And Magnetic Structure Of Multiferroic (Sr,Ba)(Mn,Ti)O3, Braedon Jones
Local Atomic And Magnetic Structure Of Multiferroic (Sr,Ba)(Mn,Ti)O3, Braedon Jones
Theses and Dissertations
We present a detailed study of the local atomic and magnetic structure of the type-I multiferroic perovskite system (Sr,Ba)(Mn,Ti)O3 using x-ray and neutron pair distribution function (PDF) analysis, polarized neutron scattering, and muon spin relaxation (μSR) techniques. The atomic PDF analysis reveals widespread nanoscale tetragonal distortions of the crystal structure even in the paraelectric phase with average cubic symmetry, corresponding to incipient ferroelectricity in the local structure. Magnetic PDF analysis, polarized neutron scattering, and μSR likewise confirm the presence of short-range antiferromagnetic correlations in the paramagnetic state, which grow in magnitude as the temperature approaches the magnetic transition. We show …

"How Could Anyone But A Madman Have Thought This Sleeping Girl Dead?": L.T. Meade's Approach To The "Buried Alive" Literary Tradition In Support Of Death Certification Reform, Shelby Johnson
Theses and Dissertations
A March 1866 issue of The Lancet observes, "If a newspaper were in want of a startling story with which to enliven a dull copy in the 'off season,' it could not do better than select one with the heading "'Buried Alive'"("Premature Interment" 295). Stories of being buried alive gave readers of all backgrounds a thrill. However, the stories frustrated the medical and scientific communities who were quick to dismiss the threat of live burial as a possibility in a modern world. Drawing on the literary history of "buried alive" stories and medical knowledge surrounding death signs and catalepsy, this …

Revisiting Marshallese Causative Constructions Using Lexical Aspect, Damon Hatch Swain
Revisiting Marshallese Causative Constructions Using Lexical Aspect, Damon Hatch Swain
Theses and Dissertations
This thesis reexamines causative constructions found in Marshallese; an Austronesian language spoken in the Republic of the Marshall Islands. Both Bender, Capelle & Pagotto (2016) and Willson (2008) hint that lexical aspect is a necessary predictor of causative behaviors in Marshallese, but offer no explanations. The primary focus of this thesis is to examine lexical aspect's influence on causative derivations. This project shows that Marshallese stative verbs display two distinct causative constructions: stative causatives and causative abstract nouns. The Marshallese causative prefix, ka-, tends to exhibit common crosslinguistic patterns of causative constructions as laid out by Dixon and Aikenvald (2000). …

Development Of Battery-Grade Silicon Through Magnesiothermic Reduction Of Halloysite-Derived Silica, Nathan Clarke
Development Of Battery-Grade Silicon Through Magnesiothermic Reduction Of Halloysite-Derived Silica, Nathan Clarke
Theses and Dissertations
The production of halloysite-derived silicon (HDS) is investigated as a potential anode material in lithium-ion batteries (LIBs). Other researchers have found HDS to be electrochemically active in small test cells. To test larger electrochemical cells, the production process needs to be scaled up and optimized. HDS is produced through magnesiothermic reduction of acid-etched halloysite. The reduction process is very exothermic and requires special consideration while being scaled up. A reactor and pressure release system were designed and fabricated to perform the reduction process in a safe manner. Various steps of the process were tested to determine their influence on the …

In-Depth Geochemical Analysis Of Turbidite-Associated Shales Of The Pindos Basin, Greece, Jonathon Michael Sevy
Theses and Dissertations
Detailed geochemical analysis of the turbidite-associated shales of the Cretaceous Katafito Formation, Greece, reveals important details regarding the paleoenvironment, paleoproductivity, and regional tectonics of the Pindos Basin. The Katafito Formation was deposited along an active margin at the early onset of closure of the Tethys Sea in the Pindos sub-basin. While careful studies of the coarse clastic component of turbidites are common, this study consisted of a detailed geochemical characterization of the fine-grained portions, which helped reveal paleoenvironmental information about the basin. This study combined organic and inorganic geochemistry utilizing elemental, mineralogical, and organic chemical signatures from fine-grained turbidite-associated sediments …
Void Formation And Mortality During Liquid Composite Molding, Jared Michael Turner
Void Formation And Mortality During Liquid Composite Molding, Jared Michael Turner
Theses and Dissertations
Within the high-performance composite manufacturing industry, there exists a need to improve the reliability of LCM (Liquid Composite Molding) manufacturing processes in producing composite parts that better approach the quality and consistency of pre-impregnated composite tapes that are cured in autoclaves with cost being a driving factor of this need. One obstacle to that end is the phenomenon of void formation during the LCM infusion processes. The formation of these voids through different mechanisms leads to composite parts with lower mechanical properties and consistency than their pre-impregnated autoclave cure counterparts. The objective of this research is to investigate the different …

The Experience Of Teaching Disengaged Students In Stem: Examined Through The Lens Of The Abc Engagement Framework, William Randall Hjorth
The Experience Of Teaching Disengaged Students In Stem: Examined Through The Lens Of The Abc Engagement Framework, William Randall Hjorth
Theses and Dissertations
Young people today are increasingly disengaged from their education. Studies indicate that of all school subjects, American students struggle to engage in STEM subjects more than others. For decades, we have known that student engagement/disengagement impacts teachers. Researchers have also claimed that engagement/disengagement can be described as a construct made up of affective, behavioral, and cognitive dimensions (ABC). However, we do not understand how teachers experience student disengagement in these three areas. At a crucial time in education, investigation into the experiences of teachers with disengaged students is needed to uncover insights which may help us understand how teachers interpret …
Finding Words For God: Poetic Foraging In Louise Glück's The Wild Iris, Rachel Cardall
Finding Words For God: Poetic Foraging In Louise Glück's The Wild Iris, Rachel Cardall
Theses and Dissertations
The primary speaker of Louise Glück's The Wild Iris is a wanderer in her own garden. She relentlessly searches for God among her foxgloves and daisies, straining to hear God's voice. Two other speakers, God and the collective plants of the garden, offer their perspectives without acknowledgement by the human speaker. Many critics read these two other speakers as, in fact, narcissistic projections of the human speaker, a God and a world made in her own image. In this thesis, I clarify that the kind of narcissistic projection that occurs in The Wild Iris is actually productive for genuine spiritual …
Pullout Strength Of Welded Wire And Ribbed Strip Reinforcement In Lightweight Cellular Concrete Backfill Behind Mechanically Stabilized Earth Wall, Mathew Robert Bueckers
Pullout Strength Of Welded Wire And Ribbed Strip Reinforcement In Lightweight Cellular Concrete Backfill Behind Mechanically Stabilized Earth Wall, Mathew Robert Bueckers
Theses and Dissertations
Lightweight cellular concrete (LCC) is a cement, water, and air entrained mixture that consists of 25-80% voids. The air voids reduce the material strength but also decrease the material weight. Due to its lightweight properties LCC is an attractive alternative to soil backfill for retained structures, such as mechanically stabilized earth (MSE) walls. Although LCC is widely used behind MSE walls, limited information exists regarding the pullout strength of MSE wall reinforcements in LCC backfill. This research attempts to fill the knowledge gap through performing pullout tests on welded wire and ribbed strip reinforcements in MSE walls to determine the …
Synthesis Of Yaku'amide A Analogues And Progress Toward Synthesis Of Virosine A, Alexander S. Ramos
Synthesis Of Yaku'amide A Analogues And Progress Toward Synthesis Of Virosine A, Alexander S. Ramos
Theses and Dissertations
The first project in this dissertation endeavors to outline the total synthesis of yaku'amide A and its analogs. Yaku'amide A is a natural product comprised of dehydroamino acids, including E-dehydro isoleucine, and unprecedented Z-dehydro isoleucine. These amino acids present a significant challenge to their synthesis owing to their unsymmetrical nature. To simplify the synthesis process, we synthesized analogs by substituting the E and Z dehydroamino acids with symmetrical subunits. This substitution facilitated the synthesis process and enabled us to obtain a similar three-dimensional structure to that of the natural product. Furthermore, biological testing of the simplified analogs revealed potency similar …
