Atomistic Calculations Characterizing Thermodynamic And Mechanical Properties Of High Entropy Alloys, Sarah O'Brien

Theses and Dissertations--Chemical and Materials Engineering

High entropy alloys (HEAs) are an exciting new class of materials. HEAs combine multiple elements in concentrations ranging from 5% to 35%. The large variation in concentrations increases the alloy’s entropy, stabilizing it. The stabilization is due to both an increased configurational entropy and increases the vibrational entropy when the alloy is at higher temperatures. This was seen for both MoNbTaW and FeNiMoW by combining the atomistic techniques: density functional theory (DFT) and density functional perturbation theory (DFPT). For MoNbTaW, the composition plays a large role in stabilizing the alloy over the configuration of elements. For the three-phase alloy, FeNiMoW, …

The Disappearance Of Shannon White, Kathryn J. Limberg

Theses and Dissertations--English

The Disappearance of Shannon White is a Mystery-Thriller novel. The aim of the piece is to explore thematic components including perseverance, socio-economic inequities, the stigmas and medical malpractice of the American mental health system in the late twentieth century, and, ultimately, to entertain. My earliest love in the literary world was science fiction and fantasy. Writers like Robert Jordan, and more recently, Simone St. James, create worlds that test the bounds of reality in a way that I find liberating, and I seek to implement this in my own work. Such authors have taught me that fiction offers freedom to …

No Hope?: Queer Negativity, Afropessimism, And The Limits Of Futurity, Colton Barton

Theses and Dissertations--English

Since their inceptions, black and queer studies have sought to articulate the positions of “black” and “queer” within American social life—often converging on the goal of liberation. This thesis examines the intersection of two “negative” theoretical frameworks—Afropessimism and anti-social queer theory (or “queer negativity”)—to interrogate both the limits and generative potential of radical negativity. Though emerging from distinct intellectual traditions, these frameworks conceptualize blackness and queerness as constitutive negations—gaps within the dominant social order that render those so marked inassimilable to normative notions of humanity. While the convergences of these theories can be illuminating, their shared pessimism risks obscuring alternative …

Preserving Nature: Mapping Patriarchal And Imperial Control In Victorian Fiction, Hannah Schultz

Theses and Dissertations--English

In Thomas Hardy’s Tess of the D’Urbervilles, a group of fallen women see “themselves and surrounding nature forming an organism of which all the parts harmoniously and joyously interpenetrated each other” (65). As relational, boundary-dissolving, ecological subjects, these women are empowered above society’s judgment, made “sublime as the moon and stars” (65). By analyzing such representations of ecological relationality in Victorian fiction, my dissertation reveals new forms of agency for women and racialized others. While many ecofeminists have historically disavowed the nature-gender link as reinforcing the shared oppression of nature and marginalized groups, I depart from this standpoint, as …

Fatal Futures: Slow Violence, Utopia, And The Postnatural Human In Contemporary American Literature, Shelby Roberts

Theses and Dissertations--English

Fatal Futures: Slow Violence, Utopia, and the Postnatural Human in Contemporary American Literature investigates the ways in which ideas of futurity are articulated in narratives that conceptualize both the end of the world and post-calamity society through the lens of a pessimistic, queer approach to understanding the future. The purpose of this project is to not only build previous research in the configurations of the body in queer, gothic, and speculative American writing as a whole, but to enter into a developing conversation surrounding Appalachian literature through the idea of kinship (the broadening of relationships both chemical and postnatural) as …

Feeling And Experience In American Women's Writing From The First World War, Anika Jensen

Theses and Dissertations--English

This dissertation analyzes the political capacity of feeling in American women’s autobiographical and semi-autobiographical writing from and about their work during the First World War. Women produced emotionally complex accounts that resist easy categorization, and I argue that attending to feeling clarifies not only their emotional experiences with war work but their social and political projects. This dissertation closely examines portrayals and rhetorics of feeling, considering the intersections of gender, class, race, and labor in impacting how feelings are depicted, negotiated, and conveyed. While British women were more compelled to perform and convey feeling according to a rigid class system, …

"These Are The Concepts Of The Father": Proclus' Solution To Parmenides' Dilemma, Daniel J. Grifferty

Theses and Dissertations--Modern and Classical Languages, Literature and Cultures

This master’s thesis will attempt to solve a dilemma presented by Parmenides in Plato’s dialogue of the same name. This dilemma arises because the young Socrates suggests that the forms may be thoughts that come to be in the soul. Parmenides responds to this statement by attempting to force Socrates to admit that this can only lead to one of two outcomes: (1) each thing thinks because it is composed of thoughts or (2) each thing does not think, even though it is composed of thoughts. Both of these outcomes are unsatisfactory and do not provide a solid grounding for …

Geochemical And Sedimentological Signals Of Bottom Water Oxygen Dynamics From Lake Tanganyika (Zambia), Njahi Mwangala

Theses and Dissertations--Earth and Environmental Sciences

Lake Tanganyika is a large, ancient freshwater body with exceptional biodiversity that is located in the East African Rift System. Lake Tanganyika’s size and longevity make its sedimentary record useful for understanding environmental changes that cross spatial and temporal boundaries. Lake Tanganyika is known to be susceptible to global warming given its tropical location. Over 12 million people living within Lake Tanganyika’s watershed rely on fishing for their income and nutrition. Changes to limnological function driven by climate could therefore have serious implications for human health and biodiversity conservation. This study focuses on using geochemical properties of modern lake bottom …
