This research has resulted in three key outcomes. First, use cases of immersive reality technologies are identified, through the lens of …

Using Visual Effects As A Means Of Establishing Or Reinforcing Scale In 3d Visual Works, Eric Dinicolantonio

All Theses

In 3D animation, visual effects help to establish and reinforce the scale of different characters and objects that are otherwise unclear. In the Fall of 2022, I taught a class about visual effects to several students. At the time, I had difficulty explaining the importance of properly scaling your 3D effects in order to add realism. With physically based effects, we must respect the laws of physics to create a visually realistic and understandable visual effect. Going through several of my previous projects, I found that I had made mistakes with scaling several of my effects. With this paper, I …

Laser Stabilization Through Optical Turbulence, Liam Vanderschaaf

All Theses

Laser jitter presents a significant issue in the fields of laser communication and sensing. There are two main categories of positional noise in regards to the instantaneous centroid of a laser propagating over long distances: jitter resulting from optical turbulence and jitter resulting from mechanical vibrations. Optical turbulence was generated using Clemson University’s Variable Turbulence Generator (VTG). The VTG is capable of creating a desired level of optical turbulence that is comparable to atmospheric conditions with fried parameters greater than 0.3 cm. A gaussian laser was transmitted through the VTG and a system of Fast Steering Mirrors and Position Sensing …

Adapting Cultural Storytelling Styles To Modern Media, Julie Huang

All Theses

In the face of modern media, it is inevitable that certain cultural art forms will fade in popularity. Some may even fade out of existence altogether. However, there are continuous efforts to reframe these cultural gems in contemporary forms to preserve them for the younger generations. Digital media, such as animation and video games, provide the perfect vehicle to bridge the gap between traditional and contemporary. This paper investigates how storytelling practices have been carried through time and the creative ways they have evolved in the face of an ever-changing mediascape.

To support this research, I present a narrative in …

Pedagogy, Sexual Violence, And Contemporary Extremist Films: Baise-Moi (2000), Irréversible (2002), And Promising Young Woman (2020), Olivia Harris

All Theses

Baise-moi (dir. Virginie Despentes and Coralie Trinh Thi, 2000), Irréversible (dir. Gaspar Noé, 2002), and Promising Young Woman (dir. Emerald Fennell, 2020) embody characteristics of the extreme. Working from James Quandt’s formative writing in 2004, I define extremism as the purposeful inclusion of transgressive themes and situations. However, each of the selected films portrays the extreme under different production styles, aesthetics, and modes of storytelling. My connections to early exploitation film (a precursor to extremist cinema) demonstrate the genre’s important history of teaching and educating. Similar to the original intent of classical exploitation films, which taught spectators about taboo topics …

Growth, Mortality, And Movement Of Endemic Bartram's Bass And Invasive Alabama Bass In Upper Savannah River Basin Tributaries, Tyler Zumwalt

All Theses

Bartram’s Bass are an endemic to the Upper Savannah River basin in North Carolina, South Carolina, and Georgia. Bartram’s Bass are facing many risks, primary among them being hybridization with nonnative Alabama Bass. More recently, nonnative Alabama Bass and their hybrid congeners have been observed moving from reservoirs into tributaries where the remaining Bartram’s Bass populations exist. Thus, for Chapter 1 we sought to better understand the threat of nonnative gene spreading in tributary systems. To do this, we 1) quantified the movement of pure Alabama Bass, Bartram’s Bass, and their hybrids, 2) assessed correlations between movement and abiotic variables, …

Cú Chulainn's "Vigil On The Hound Fords": The Centrality Of Borders In The Táin Bó Cuailnge, David Atkinson

All Theses

This thesis examines the role of the Irish hero Cú Chulainn as a guardian of both supernatural and human borders in the popular medieval Irish saga, the Táin Bó Cuailnge. As a descendent of both the human inhabitants of Ireland and the supernatural síd, Cú Chulainn is uniquely situated to negotiate the border between the two worlds these peoples inhabit. The ambiguous distinction between these two worlds is reflected by the river borders that divide Ireland into its shifting land holdings and kingdoms. The ambiguity at the heart of this saga has given it enormous potential for adaptation through …

Influence Of Potassium Fertilizer Application Timing On Cotton Production As Related To Soil Potassium On U.S. Coastal Plain Soils, Shruthy Suresh Kumar

All Theses

Understanding soil K dynamics is highly significant in cotton production owing to its prominent role in cotton fiber quality. About 31 % of cotton production in the U.S. is concentrated in SE states, with coastal plain soils having low innate K availability. Crop fertilizer-K recommendations are primarily made worldwide and across the U.S. using pre-plant STK concentrations. A literature review on cotton K studies suggests that fertilizer-K recommendations based on pre-plant STK concentrations alone need fine-tuning to meet the increasing K demands in modern cultivars, variations in crop K requirement patterns, and varied soil K supplying capacity. Studies have been …

Fatigue Performance Of Flexural Retrofits For Precast Slab Bridges, Ian Stewart

All Theses

This thesis discusses flexural and cyclic load testing of two potential retrofits for pre-cast slab bridges. These slabs came from South Carolina Department of Transportation (SCDOT) decommissioned bridges as a part of an ongoing project with SCDOT. The first is a Carbon Fiber Reinforced Plate (CFRP) retrofit where four CFRP plates were adhesively bonded to the bottom of a slab. The second is a steel plate that was mechanically attached to the bottom of a slab using bolted connections. The bolts were cast into grouted holes in the slab. To better understand the failure mode of these retrofits and their …

Japan’S Minorities: Nations Within A Nation, Christopher Shumard

All Theses

This thesis concerns the modern history of Japan’s ethnic minorities. These are the Zainichi Koreans, the Okinawans or Ryukyuan People, and the Ainu. Analyzing the feelings expressed in their literature, the constitution of and shifting nature of each group’s identity is tracked. The central argument of this thesis is that there is something innate to the human adherence towards group identity. It is the goal of this work to prove this claim through Japan’s three ethnic minorities which demonstrated this shared tendency and desire for a solid group identity around which individuals clustered under dire circumstances. These circumstances originated with …

Meta-Analysis Of The Effects Of Endophytes And Their Secondary Metabolites On Herbivory From Insects, Derrick Taylor

All Theses

Endophyte-infected plants have reduced the level of herbivory. The defense to herbivory can vary due to the metabolites in the plant and the method of feeding from the pest. Secondary metabolites produced by the endophytes are mainly alkaloids. The associations between endophytes and some alkaloid groups are studied in greater detail. The lack of research of certain alkaloid groups ultimately means that some alkaloids had more data that could be analyzed. As a result, the alkaloid groups were not evenly represented in the meta-analysis. The meta-analysis analyzed the relative effectiveness of the metabolites or endophytes in each of the articles …

Pyrolysis—A Tool In The Wastewater Solids Handling Portfolio, Not A Silver Bullet: Benefits, Drawbacks, And Future Directions, Patrick J. Mcnamara, Zhongzhe Liu, Yiran Tong, Hari Santha, Lynne Moss, Daniel Zitomer

Civil and Environmental Engineering Faculty Research and Publications

Pyrolysis is the process whereby carbonaceous materials, such as biosolids, are heated between 400°C and 900°C in the absence of oxygen. Three main products are generated: a solid product called biochar, a py-liquid that consists of aqueous phase and non-aqueous phase liquid, and py-gas. The biochar holds value as a beneficial soil amendment and sequesters carbon. The py-liquid is potentially hazardous and needs to be dealt with (including potentially reducing it on-site via catalysis or thermal oxidation). Py-gas can be used on-site for energy recovery. Pyrolysis has gained recent interest due to concern over per- and polyfluoroalkyl substances (PFAS) in …

Early Solid Diet Supplementation Influences The Proteomics Of Rumen Epithelium In Goat Kids, Yimin Zhuang, Xiaokang Lv, Kai Cui, Jianmin Chai, Naifeng Zhang

Animal Science Faculty Publications and Presentations

It is well known that solid diet supplementation in early life can significantly promote rumen development and metabolic function in young ruminants. However, the changes in the expressed proteome and related metabolism in rumen epithelium in response to a supplemented solid diet remain unclear. In this study, rumen epithelial tissue from goats in three diet regimes including milk replacer only (MRO), milk replacer supplemented concentrate (MRC), and milk replacer supplemented concentrate plus alfalfa pellets (MCA) were collected for measurement of the expression of epithelial proteins using proteomic technology (six per group). The results showed that solid diet significantly improved the …

Owning The Body: Bodily Autonomy And Consent In The Works Of Octavia Butler, Korryn Plantenberg

Theses/Capstones/Creative Projects

During the 1980’s the Second Wave feminist movement provided more interest in interdisciplinary movements towards equity in the case of gender. One movement that slowly grew was Womanism, which included the intersection between race and gender. Specifically, the experiences of black women in the United States. Inspired by this movement authors such as Octavia Butler was a black science fiction author who wrote literature focused on black women. Alongside her preoccupation, with race in science fiction, Butler explores the nature of consent and bodily autonomy in utopian and dystopian futures. Within her novels, she uses Womanism to engage with futuristic …

Veterinary Access Barriers Experienced By Urban Versus Rural Clients: A Case Study In Middle America, Molly Andreasen

Theses/Capstones/Creative Projects

The comparison of urban versus rural clientele as to their access to veterinary care and preferences regarding veterinary services has received little research attention. A better understanding of client perspectives is critical for ongoing efforts to provide more equitable availability of veterinary services across varying demographic areas. In this study, I directly assess differences in access to veterinary services based on client perspectives from both rural and urban locales across Nebraska, USA, a state almost directly in the middle of America. It was expected that rural clients would experience more barriers to veterinary access in general and with respect to …

An Emergentist Critique Of The Contract Theory Of The State Of Nature, With A Consideration On Two Types Of Polity And Their Origins., Ryan A. Apperson

College of Arts & Sciences Senior Theses

The theories of the state of nature provided by the political philosophers Thomas Hobbes and John Locke have made a significant impact in the general conceptions of the origin of states. Though there are many critical differences in the conceptions of the state of nature between each in their seminal works, they both possess of a view of states that is rational and constructivist.

In this paper, I use the game theory concepts of the coordination game, collective action problem, and focal point to illustrate a lacuna in this rational and constructivist conception of the origin of states, as their …

Impact Of Lyophilization On Porcine Hemoglobin Properties., Mustafa Almosawi

College of Arts & Sciences Senior Theses

Blood transfusion is the single most often performed lifesaving procedure in hospitals worldwide. Unfortunately, packed red blood cells (RBCs) used for transfusion can only be stored for 42 days at 4 °C before being discarded due to irreversible damage that occurs during storage. Any reduction in available RBCs for an extended period can lead to blood shortages. To increase the shelf-life of RBCs, we investigated freeze-drying (lyophilizing) in the presence of the non-toxic sugar trehalose as a method for long-term preservation. However, the oxidative stress of the lyophilization and storage processes can compromise the functionality of these cells, and the …

Transferred Emissions Are Still Emissions: Why Fossil Fuel Asset Sales Need Enhanced Transparency And Carbon Accounting, Jack Arnold, Martin Lockman, Perrine Toledano, Martin Dietrich Brauch, Shraman Sen, Michael Burger

Columbia Center on Sustainable Investment

In a widely reported trend, the “Oil Supermajors” — BP, Chevron, ConocoPhillips, Eni, ExxonMobil, Shell, and TotalEnergies — are selling off many upstream fossil fuel assets.

Selling these assets to entities that will continue producing and selling the fossil fuel resources does not necessarily reduce greenhouse gas emissions, but the supermajors have used these asset sales to support claims that they are making progress toward reaching net-zero greenhouse gas emissions.

Emissions reporting frameworks allow companies to conflate the apparent emissions reductions from asset sales with direct reductions from efficiency improvements and asset retirements. In doing so, they hinder the ability …
