Cfd Investigation Of Heat Transfer Enhancement In Pipes Using Gyroid Tpms Structures For Industrial Steam Generation, Alejandro Moreno Escribano

Graduate Studies Theses and Dissertations 2026

Industrial heating processes account for nearly 28\% of global CO2 emissions, and fossil fueled boilers predominate in high temperature applications. Industrial electrification can be an effective solution when combined with renewable energy sources. Increasing steam generation efficiency and at the same time maintaining system compactness is a significant challenge in industrial thermal processes. Traditional smooth pipes offer limited heat transfer surface area, which constrains boiling heat transfer performance and reduces the overall efficiency of steam generation systems. Advanced internal geometries have the potential to significantly enhance heat transfer by increasing surface area and promoting fluid mixing. This work presents a …

The Intersection Of Abuse, Child Welfare, And The Law For Intimate Partner Violence Survivors: Gender Violence As An Antagonistic Social Force, Julio Montanez

Revolution In The Age Of Social Media: A Mathematical Model For Information, Dissent, And Stability, Killian Muollo

Graduate Studies Theses and Dissertations 2026

Revolutions, defined by Skocpol as rapid transformations in class, state, and/or social structures, are important world events that can cause civil wars, spark international trends, and result in transitions toward democratic and autocratic regimes alike. They are characterized largely by the mechanism of mass mobilization, which is increasingly facilitated by online networks and digital communication. In this dissertation, we investigate such means and outcomes of revolutions as dynamical systems. We construct three models describing separate but complementary aspects of revolution, beginning at the smallest unit of analysis and then moving outward in scope. First, we construct a graph-based model to …

"Time And Place Have Had Their Say": A Digital Historical Context Guide To Zora Neale Hurston's Their Eyes Were Watching God, Anna Kephart Norris

Graduate Studies Theses and Dissertations 2026

Harlem Renaissance author, anthropologist, and folklorist Zora Neale Hurston (1891-1960) is best known for her 1937 novel Their Eyes Were Watching God. As part of the modern American literary canon, Their Eyes Were Watching God is assigned in countless secondary and post-secondary classrooms across the United States each year. Yet students find the book difficult to understand and educators find it challenging to teach due to its dialect, racial themes, and nuanced historical setting. In this paper, I argue that better understanding of Their Eyes Were Watching God's historical context eases these difficulties in reading and teaching the …

Exploring The Role Of Hes4 During Retroviral Infection, Raphael Opoku

Graduate Studies Theses and Dissertations 2026

Human immunodeficiency virus (HIV) infection disrupts immune homeostasis and impairs antiviral defenses, partly by compromising natural killer (NK) cell activity, with simian immunodeficiency virus (SIV) infection in rhesus macaques serving as a valuable model to investigate these mechanisms. This research examines the regulatory role of HES4 and its isoforms in NK cell function during retroviral infection, with particular focus on how Notch signaling–dependent regulation of HES4 shapes NK effector responses. HES4, a downstream effector of the Notch signaling pathway, encodes transcriptional repressors central to immune cell differentiation, yet its contribution to NK cell biology remains poorly understood. Using molecular and …

The scattering data and transition dipole moments for the molecular systems were calculated using R-matrix method through the UKRMol+ codes. A vibrational frame transformation is then performed and multi-channel quantum defect theory is used to calculate closed …

Old Maps Of The New World & New Theories On The European Encounter With La Florida: An Historical Archaeological And Four Field Anthropological Approach To Peter Apian's Cosmographia (1575), Emerson S F Richards

Graduate Studies Theses and Dissertations 2026

This thesis examines the 1575 Spanish edition of the Cosmographia, a geographic textbook initially authored by Peter Apian and expanded by Gemma Frisius, as a source for anthropological inquiry into early European encounters with the Americas. Little attention has been given to the text’s potential as a source for anthropological analysis, particularly regarding its representations of the Americas and the cultural information embedded in the geographic data. This study addresses that gap by applying a Four-Field anthropological framework—cultural, biological, linguistic, and archaeological—to this edition, which incorporates excerpts from Ieronimo Girava’s qualitative and quantitative description of the Americas, including a …

Characterization And Antibacterial Assessment Of An Isoborneol-Loaded Nanoemulsion, Sharon M. Rodriguez Villacis

Graduate Studies Theses and Dissertations 2026

In the United States, about 35,000 fatalities occur annually due to antibiotic resistant infections. It is progressively becoming one of the largest challenges when treating hospital-acquired infections. This decline in effectiveness of commonly used antibiotics makes it essential to identify, synthesize, and formulate compounds that possess antimicrobial activity against these common pathogens. Isoborneol, a compound that is naturally occurring terpene that can be derived from the Camphor tree, Cinnamomum camphora, is known for its antimicrobial properties in traditional medicine and in prior literature. To assess this hypothesis, an oil-in-water (OW) nanoemulsion of isoborneol was synthesized, characterized, and assessed for …

Source Credibility And Chatbots: How Design Factors Impact Chatbot Effectiveness, Kristen M. Schmidt

Graduate Studies Theses and Dissertations 2026

Source credibility theory states that the more credible a source appears to be, the more likely one is to believe both true and untrue information from it. In the modern day, misinformation is considered a major problem, particularly with virtual communication, meaning it is essential to study what factors influence a system’s source credibility. Virtual agents are a particularly relevant subject of study given that their source credibility can be impacted by both technological and social factors. Across three experiments, this dissertation utilized a novel chatbot interaction design to test how varying design factors would impact a chatbot’s source credibility …

Tl;Dr (Too Long; Didn't Read): Examining The Assessment And Causes Of Careless Responding Within Experimental Vignette Studies, David L. Sexton Jr.

Graduate Studies Theses and Dissertations 2026

Careless responding occurs when participants answer survey items without considering their content and poses a serious threat to data quality. However, while past research has examined its deleterious effects on both survey and low-stakes cognitive ability measures, little research has focused on careless responding in experimental vignette methodology (EVM) research. EVM studies require participants to attend to one or more experimental vignettes, which are carefully crafted written scenarios designed to manipulate a focal variable across conditions. However, if participants are careless in attending to study vignettes, they may not be exposed to the researchers’ intended experimental manipulations, thereby precluding them …

Data-Driven Seismic Site Classification Using Earthquake And Microtremor Horizontal-To-Vertical Spectral Ratios, Sanidhya Sharma

Graduate Studies Theses and Dissertations 2026

The prevailing seismic site classification parameter, the time-averaged shear-wave velocity in the upper 30 meters (V_S30), provides an incomplete representation of site conditions, neglecting deeper geology, impedance contrasts, and resonance phenomena. This thesis developed and validated a data-driven framework for seismic site classification based on the full spectral shape of Horizontal-to-Vertical Spectral Ratio (HVSR) curves combined with unsupervised machine learning, through two complementary research studies. Research 1 applied K-means clustering to earthquake-based HVSR (eHVSR) data from 3,186 ground motion stations across California and adjacent regions, identifying four physically distinct site clusters, characterized by low-frequency, very-low-frequency, high-frequency, and …

Masculine Devotion And Moral Decay: The Paradox Of Chivalry In Malory's Le Morte Darthur, Julia Annunziato

Graduate Studies Theses and Dissertations 2026

This thesis investigates how, within Sir Thomas Malory’s Le Morte Darthur, the concept of chivalry as a literary construct is misunderstood and misrepresented by the knights who attempt to uphold it. Through a close reading of Le Morte, this paper concludes that Malory presents chivalry not as a coherent moral code, but as a paradoxical system that both promotes and undermines the values it claims to uphold. While chivalry is typically meant to emphasize honor, loyalty, and spiritual devotion, Malory’s narrative reveals how these ideals are compromised by structures of masculine competition, performative identity, homosocial desire, and corrupted …

Lucha Libre: Legends Of The Mask, Anthony J. Aguilar

Graduate Studies Theses and Dissertations 2026

Lucha libre, also known as Mexican wrestling, is a cultural phenomenon whose history dates to 1933. Every wrestling match pits flamboyantly costumed and masked wrestlers (luchadores), classified as either the good guys (técnicos) or the bad guys (rudos), against each other in choreographed and dramatized battles. Although lucha libre is often seen as campy or “low brow” due to its exaggerated, theatrical style, this perception overlooks the deeper cultural significance and narrative potential inherent in the form. This thesis will explore the cultural evolution of lucha libre as a highly interactive themed ride attraction. By integrating guest participation through custom …

Un Lugar A Donde No Puedo Volver: Perteneciendo En La Distancia, Alberto J. Alonso

Graduate Studies Theses and Dissertations 2026

“A Place I Cannot Return To: Distance and Belonging” investigates how home is not limited to a fixed place, but instead a reconstruction sustained through memory and longing, which focuses on personal experiences of being away from Puerto Rico. I contribute to this broader dialogue by offering a deeply personal perspective shaped by the complexities of cultural belonging. Through photography, collage, and painting, my art practice reconstructs fragmented visual narratives of lived experience to explore homesickness, nostalgia, and displacement, examining how personal and shared histories become anchors to what continually slips away. Although I can physically return to Puerto Rico, …

Critical Analysis Of Legal Education: Faculty Perspectives Of Law School's Role In Producing Practice-Ready Graduates, Sophia M. Akel

Graduate Studies Theses and Dissertations 2026

Legal education has long been the subject of harsh, widespread criticism due to concerns about its ability to adequately prepare students for legal practice. Newer attorneys have reported feeling incapable of performing even the most basic functions of their job after graduation from law school (Merritt & Cornett, 2020). Despite this troubling reality, law schools largely continue to function as they always have (Cramton, 1981). To gain insight directly from important figures in legal academia, this study examined law faculty perceptions on legal education’s role in producing practice-ready graduates. A mixed-methods survey design incorporating both quantitative descriptive and qualitative elements …
