The Urban Heat Island And Its Role In Shaping Convective Environments: An Observational Study, Benjamin W. Moll

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The continued spread of urbanization and its well-documented effects on regional weather and climate necessitate further research. Urban environments are often warmer and drier than their rural surroundings. This trade-off between a warmer but drier environment could have a complex impact on deep convection and its initiation. Previous studies have noted significant changes in precipitation patterns around cities as well as changes to ongoing deep convection. Given the well-documented theory and past research, it is hypothesized here that urban areas have a significant impact on the PBL thermodynamics of convective environments. The urban heat island (UHI) component of the Micro …

Evaluating The Role Of Seaweeds In Dairy Production: Impacts On In Vitro Ruminal Fermentation, And In Vivo Mineral Utilization And Metabolic Status, William Mitchell Sims

Doctoral Dissertations

Dietary inclusion of seaweed in ruminant diets has been studied for more than 5 decades. Early research in seaweed focused primarily on potential health benefits, but recent interest has shifted the paradigm for its use as a nutritional tool to mitigate greenhouse gas emissions. As new seaweeds are identified for their ability to reduce gas emissions, the pendulum will swing once more to understand the impact seaweeds have on ruminant health and production. The overall objective of this dissertation is to investigate digestibility and fermentation, as well as alterations in metabolic and mineral status in ruminants fed various seaweed species. …

Development And Characterization Of Bulk Dsdna-Based Materials Using Biologically Derived Plasmid Dna, Wynter Amythyst Paiva

Doctoral Dissertations

Double-stranded DNA (dsDNA) exhibits many unique sequence-independent properties that remain underutilized in materials science. The exceptional length, solubility, biocompatibility, imageability, molecular recognition capabilities, and topological control of DNA makes it an ideal candidate for the creation of bespoke biomaterials and investigation of fundamental relationships in polymer physics. Unfortunately, translation of DNA-based materials from the microscale to macroscale has been hindered by source constraints and limitations in chemical modification of biologically derived DNA. This work seeks to expand the utility of dsDNA from the benchtop to real world applications. Establishing dsDNA as a commodity polymer will aid in the development of …

The Baroclinic Route To Acoustic Streaming: Mechanisms Of Mean-Flow Generation And Heat Transport In Acoustically-Forced Stratified Fluids, Remil Mushthaq

Doctoral Dissertations

Standing acoustic waves in density-stratified fluids confined within horizontal channels generate fluctuating vorticity baroclinically, driving mean streaming flows that are much stronger and qualitatively distinct from classical Rayleigh streaming. Theoretical and numerical studies have shown that these baroclinic acoustic streaming flows can reach speeds comparable to the maximum speed of the oscillatory sound-wave field, enabling fully two-way wave/mean-flow coupling: the streaming flow modifies the background density field, which then alters the structure of the acoustic waves. Extending this framework, Massih (2022) quantified the heat-transfer enhancement arising from baroclinic streaming as a function of the channel aspect ratio (δ). The present …

Investigation Of Cross-Flow Turbines With Varying Structural And Surface Properties, Nicole Marone

Doctoral Dissertations

The oceans are a largely untapped resource with regard to their tidal, wave, and ocean current energy potential and could significantly contribute to clean energy objectives. Cross-flow turbines (CFTs) can be used to extract energy from tidal currents and provide electrical energy to the power grid. However, one of their main barriers to market entry is their levelized cost of energy (LCOE), which at present is still quite high. Three parameters that have not previously been studied together, and that could make CFTs more cost-competitive, include the use of less rigid and less expensive materials, a reduction in the number …

Adrift: The Influence Of Shelf Circulation And Larval Dispersal On Coastal Biogeography At Basin And Global Scales, Will Lush

Doctoral Dissertations

The dispersal of larvae plays an important role in determining the distribution of benthic meroplanktonic organisms in the coastal ocean. The work presented in this defense uses biophysical modeling approaches to examine the interaction of larval dispersal with coastal circulation and the impact of these interactions on contemporary coastal biogeography at global scales.I begin by presenting a novel method for validating numerical dispersal estimates against drifter observations from the Global Drifter Program. We find that median dispersal estimates match observations to within 5 percent, while model estimates underpredict the spread of drifters around this median by between 30 and 50 …

Mindreading And Embodiment: Beyond Mirror Neurons., Sanad Al Khatib

College of Arts & Sciences Senior Theses

This paper examines the question: how do we figure out what other people are thinking and why they act as they do, or put differently, how is it that we can read minds in daily life? For decades, the dominant view held that we explain and predict other people’s behavior by attributing to them mental states such as beliefs, desires, and intentions, represented symbolically in the brain. The embodied simulation model challenges this view, proposing that understanding others primarily relies on mirror neurons that activate both when we perform an action and when we observe someone else performing it. This …

Energy Assimilation And Thermoregulatory Behavior In Populations Of A Vertebrate Ectotherm (Sceloporus Consobrinus) Along A Geographic Thermal Gradient, Brandon Wolfsohn

Biology Theses, Dissertations, and Student Creative Activity

Ectothermic organisms make up a vast majority of animal species and fill many vital roles in ecosystems due to their prevalence. Because ectotherms are inherently affected by the thermal environment, they are severely impacted by environmental issues such as climate change and other human driven processes that may affect thermal habitats. To better understand how ecosystems are affected by changes in climate, we need a greater understanding of how ectothermic organisms respond and adapt to altered environmental temperatures. This study aims to understand some of the adaptational differences between populations of a widespread lizard species, Sceloporus consobrinus, that inhabit a …

Political Discoveries In A Žižek Substack Project Critical Digital Studies, Edward Sankowski, Betty J. Harris

International Dialogue

This review essay analyzes Slavoj Žižek’s recent turn to Substack as a publishing platform, examining both his motivations and the philosophical and political implications of this medium for contemporary critical theory. Sankowski and Harris argue that Žižek’s Substack writings continue long-standing themes in his work—anti-capitalism, ecological crisis, updated Communism, and the cultural dimensions of ideology—while also revealing notable shifts, including heightened pessimism about historical progress and new reflections on environmental catastrophe. The authors assess the advantages and pitfalls of Substack for intellectual discourse, including its circumvention of traditional editorial “censorship,” its contribution to information glut, and its role in fostering …

N-Aryl Phenoxazines As Polymer Supported Photocatalysts, Mary Kathryn Hall

Master's Theses

In photosynthesis, the energy of sunlight is perfectly harnessed to facilitate the production of small molecules that are essential for plant life on earth. Inspired by this model of energy efficiency and simplicity, this work seeks to mimic that ability to use the energy in visible light to perform new and more efficient chemistries. Just like in photosynthesis, photocatalysts can act as chromophores absorbing light to excite electrons opening new pathways for previously untapped reactivity. Recent research has provided a wide range of small molecule reactions that are made possible or easier by the use of a photocatalyst. However, these …

Effectiveness Of Education On Increasing Training Likelihood: An Analysis In Relation To Physique Inflation, Reid J. Venable

Honors College Theses

Resistance training is a widely recommended form of exercise for enhancing muscular strength, improving metabolic health, and promoting overall quality of life. In addition to these benefits, perhaps the most popular reason for participating in resistance training is to achieve muscle hypertrophy and attain a desired or aesthetic physique. However, various factors such as the use of performance-enhancing drugs and social media have led to “physique inflation,” a cultural phenomenon in which exposure to highly enhanced or unrealistic body types shifts perceptions of what is considered a “normal” or attainable physique. As a result, many individuals avoid or delay resistance …

What Does Genius Look Like? Investigating Brilliance Bias In Ai-Generated Images, Juliana Shihadeh, Margareta Ackerman, David Loker

Computer Science and Engineering

Text-to-image models, like Midjourney, DALL-E, and Stable Diffusion, have been shown to reinforce harmful biases, often perpetuating outdated and discriminatory stereotypes. In this study, we delve into a particular bias largely overlooked in generative image research: Brilliance Bias. By age 6, many children begin to internalize the damaging notion that intellectual brilliance is a male trait—a belief that persists into adulthood. Our findings demonstrate that popular image AI models possess this bias, further entrenching the misguided notion that exceptional intelligence is inherently male. This study calls for addressing brilliance bias in AI to ensure a more realistic representation of intellectual …

Polypropylene/Polyethylene Blends With Asymmetric Viscosity: Fabrication, Characterization, And Recycling Potential, Bernadine Daichendt

All Dissertations

Polyolefin materials, polypropylene (PP) and polyethylene (PE), are widely used in day-to-day life both commercially and industrially, offering versatile applications due to their mechanical and chemical properties. The high consumption rate of these materials makes them important targets for recycling efforts. However, there are multiple contributing factors leading to low recycling of PP and PE, chiefly sorting factors: chemical similarity, changed properties after multiple rounds of processing, and the use of processing aids. It is necessary to point out that, because of multiple melt processing cycles, recycled PP has decreased molecular weight due to chain scission. Conversely, recycled PE molecular …

Degradation Of Cobalt Chrome Molybdenum Hip And Knee Implants In Vivo And In Vitro, Peter William Kurtz

All Dissertations

Cobalt Chrome Molybdenum (CoCrMo) remains a popular material choice for femoral condyles in total knee arthroplasty and for acetabular liners in dual mobility total hip designs. CoCrMo has been phased out of conventional THA designs due to its correlation with adverse effects such as ALTR and ALVAL. It is less understood if the mechanisms (i.e. abrasive wear to the surface of the implant) that release metal ions into the surrounding tissue occur at similar rates as seen in conventional THA. Additionally, it is unknown what effect the secondary damage modes such as electrocautery damage and adhesive wear have on these …
