Modeling Vibration Stiffness: An Analytical Extension Of Hertzian Theory For Angular Contact Bearings With A Thin Viscoelastic Coating, Davis R. Burton May 2024

Modeling Vibration Stiffness: An Analytical Extension Of Hertzian Theory For Angular Contact Bearings With A Thin Viscoelastic Coating, Davis R. Burton

Honors Theses

This thesis considers the novel angular contact rolling-element bearings proposed by NASA’s Glenn Research Center, which are coated with a thin solid lubricant that exhibits viscoelastic behavior. Current analytical models for the dynamic stiffness matrix of angular contact bearings, critical for vibration analysis, lack the ability to model the effects of a solid coating, as well as the time dependencies inherent in viscoelastic theory. The author first presents an overview of the stiffness matrix derivation, followed by a treatment of the underlying Hertzian contact theory. An analytical extension of this theory is proposed which accounts for a thin elastic layer …

Exploration Of Cytotoxicity Of _Rabidosa Rabida_ Venom On Invertebrate And Vertebrate Cell Cultures, Martina Gooden

Honors Theses

Venom has been observed in thousands of species across different taxa. It can be adapted for different purposes, including prey capture or predator defense. Venom is found almost universally in spiders, but there has been little exploration of spiders that are not medically significant. Rabidosa rabida, the rabid wolf spider, is a common species whose venom has not been adequately investigated. Previous studies indicate that they do not require venom to apprehend easy prey in a laboratory setting, raising a question as to what their venom is adapted to do. To evaluate its effect on mammalian cells, L929 murine fibroblasts …


Development Under Erasure: Deconstruction In Development Discourse, Micah Gill Apr 2024

Development Under Erasure: Deconstruction In Development Discourse, Micah Gill

Honors Theses

Jacques Derrida’s theory of deconstruction has been historically underappreciated in development. Yet Derrida’s critical theory realizes development as an inherently deconstructive field, one which advocates for the Other when disciplines such as economics and international relations overlook them. By examining the history of development through a Derridean lens, we can see how deconstruction was working within some of the development discourse’s prominent shifts leading up to its “impasse” in the 1980s. Heightened critical attention around this time catalyzed a flurry of deconstructive processes in the following years which have reshaped the landscape of development scholarship and practice. The story of …


Dispelling Delusion And Seeing Nature: A Comparative Analysis Of Lucretius’ _De Rerum Natura_ And Hui-Neng’S _Platform Sutra_, Isaac Raymond Apr 2024

Dispelling Delusion And Seeing Nature: A Comparative Analysis Of Lucretius’ _De Rerum Natura_ And Hui-Neng’S _Platform Sutra_, Isaac Raymond

Honors Theses

Lucretius’ De Rerum Natura and Hui-neng’s Platform Sutra have never been compared in a scholarly context; as such, this paper builds a new bridge between Western and Eastern philosophical literature, examining language, narrative, ethics, teleology, theology, and departures from orthodox philosophies in order to synthesize a clear and complete view of the two works in dialogue. De Rerum Natura, or On the Nature of Things, is a first-century BC epic poem composed in Latin by Titus Lucretius Carus which explains Epicurean philosophy in great detail through verse. The Platform Sutra is an eighth-century AD Chinese Zen (Ch’an) Buddhist sermon, …


The Mitre And Crown: The Relationship Between The Church And Crown In Norman-Angevin England, 1066-1215, Isaac Copeland Apr 2024

The Mitre And Crown: The Relationship Between The Church And Crown In Norman-Angevin England, 1066-1215, Isaac Copeland

Honors Theses

From the Norman invasion in 1066 to Magna Carta in 1215, the balance of power between the Mitre and the Crown in Norman- Angevin England shifted from being defined through personal relationships to being defined by charters. This shift occurred due to a cycle of conflict and cooperation between Church and Crown, and during the periods of peace, kings, archbishops, and popes created models that delineated boundaries of power between the Church and the Crown. Over a century and a half, four functioning models emerged: the Crown-led Personal model created by William the Conqueror and Archbishop Lanfranc from 1066-1089, the …

The Third Horseman: Preventability Versus Apocalypse In The Great Famine Of 1315 And The Irish Potato Famine, Luke Ziegler

Honors Theses

Famine is a huge problem for societies, even in the modern world. Throughout history, famine has reared its ugly head and brought about demographic and societal collapse. The Great Famine of 1315 Famine and the Irish Potato Famine, despite their differences, had similar underlying factors of land management and overpopulation paired with an environmental catalyst, and also show that governmental response has the potential to both cause and prevent a famine, but only if the scale of the problem is limited. They both examine the question of national identity and create a multitude of debates in later historiography. Although these …

Making Good Doctors: The Ama’S Code Of Ethics And A Culture Of Virtue, John Howard Hassmann Feb 2023

Making Good Doctors: The Ama’S Code Of Ethics And A Culture Of Virtue, John Howard Hassmann

Honors Theses

The American Medical Association’s (AMA) Code of Medical Ethics consists of principles that ensure the legal sanctity and professional conduct of practicing physicians. These principles outline imperatives for physicians “primarily for the benefit of the patient. But a physician can be terrible without violating the AMA’s Code of Medical Ethics. Although the AMA’s code ought not be forsaken or replaced, any code of ethics cannot make its adherents good. Physicians cannot become good following a code that neglects to address the delicacy of good habits. Further, a topical, crisis-management approach to ethical training stifles physicians whose ethical goals transcend lawfulness …

Through utilizing a narrative intervention alongside measures of prejudiced attitudes, empathetic capacity, and narrative identification, this study documents how students at a Christian university in the southern United States (n = 100) responded to narrative persuasion. While analyses revealed that the narrative intervention was ineffective in significantly affecting prejudiced attitudes towards women, participants’ empathy levels were positively correlated with character identification, further elucidating the process of perspective-taking. Despite some non-significant results, this study sheds light on the role of narrative persuasion on students at a Christian university …


Exploring The Impacts Of Student Classification On Perceptions Of Success, Mackenzie Richmond Apr 2022

Exploring The Impacts Of Student Classification On Perceptions Of Success, Mackenzie Richmond

Honors Theses

There are several definitions of success, and everyone has their own personal take. Some define success as receiving honors, rewards, or having good relationships, while researchers have their own success vocabulary. Although there is a battle between logic and sociality for perceptions of success, it is commonly agreed that success is linear and multifaceted. The purpose of this study is to explore the impact of student classification (undergraduate and graduate/professional students) on perceptions of success. Knowing how someone perceives success offers insight into that person. Such insight can equip therapists on ways to personalize a therapeutic approach, including goals and …


"Freedmen Not Freemen": The Freedmen's Bureau And Black Land Ownership In Arkansas, Eric Johnson Apr 2022

"Freedmen Not Freemen": The Freedmen's Bureau And Black Land Ownership In Arkansas, Eric Johnson

Honors Theses

When slavery ended at the close of the Civil War, there was no universal answer for where former slaves were to live. The type and quality of freedom Black Southerners would experience during Reconstruction would be largely determined by where they lived. Many freedpeople and Republicans desired for widespread Black land ownership across the South. “Forty acres and a mule” was a common phrase that spread throughout the South and represented the hope that the United States government would ensure that all former slaves would be given land to own and live on. The Freedmen’s Bureau, which was created under …

Microglia Polarize In Response To Transactive Response Dna-Binding Protein-43 (Tdp-43) And Display Partial Recovery After Removal Of The Stimulus, Alicen Wilcox Sep 2021

Microglia Polarize In Response To Transactive Response Dna-Binding Protein-43 (Tdp-43) And Display Partial Recovery After Removal Of The Stimulus, Alicen Wilcox

Honors Theses

The proper response to protein signals is necessary for a healthy central nervous system (CNS), and protein dysregulation is a feature of neurodegenerative diseases. Transactive response DNA-binding protein-43 (TDP-43) is an intranuclear protein, but mislocalization is associated with amyotrophic lateral sclerosis (ALS). TDP-43 is released into the extracellular space where it is sensed by microglia, the CNS-resident immune cells. Our data and the literature suggest that microglia respond to TDP-43 dysregulation by increasing CNS inflammation. The goal of this study was to determine the impact of TDP-43 on microglial function and the extent to which microglia recovery. To study the …


In His Image And Into His Likeness: Human Nature's Theosis In C.S. Lewis's Till We Have Faces: A Myth Retold, Jacob Ross Taylor Apr 2021

In His Image And Into His Likeness: Human Nature's Theosis In C.S. Lewis's Till We Have Faces: A Myth Retold, Jacob Ross Taylor

Honors Theses

C.S. Lewis’s standalone title Till We Have Faces: A Myth Retold transforms the Greek mythos “Cupid and Psyche” into a novel about human nature being deified. In TWHF, Lewis presents an arc from pagan dualism through rationalism and finally to our relational God who makes us holy like Him. Lewis studies have suffered from the lack scholarship applying St. Thomas Aquinas’s christened Aristotelianism which would illuminate the metaphysical foundations that Lewis founds his words and builds his worlds upon. In Aristotle metaphysical biology he proposed that the human soul is neither an altogether separable spirit divorced from the bodily …
