Host Response To Implantation Of A Poly N-Isopropylarylamide Injectable Cell Therapy Vehicle, Cole Matthew Burk

Master's Theses

There is a need to develop novel and effective therapies targeting end-stage peripheral arterial occlusive disease (PAOD). Inducing collateral arteriogenesis is a possible novel treatment that produces a natural bypass for blood flow, a promising solution to the long-term issues seen with current treatments. Regenerative therapies, and progenitor cells specifically, have demonstrated great promise in repair after injury and disease. While most progenitor or stem cells have poor efficacy in this context, muscle progenitor cells, or myoblasts, have encouraging results. Myoblasts enhance arteriogenesis and secrete cytokines or chemokines that recruit monocytes to injury sites. Implanting these adherent cells in a …

Pokémon Go: Fostering Community In Location-Based Augmented Reality, Miranda Ward

Communication Studies

While most modern video games are played from the comfort of one's own home, Pokémon GO (2016) is a game that requires people to leave their homes and interact with other people in the real world. Pokémon GO contains community-building mechanics that reward players for interacting with each other and catching Pokémon. Due to this, players use third-party applications to organize meetups, particularly through Campfire, which is an app owned by the same company who created the game, Niantic. Uses and Gratifications Theory can be applied to understand why players choose to play Pokémon GO and what needs the game …

Quantifying The Mechanisms Behind Carbon Sequestration And Soil Health Following Compost Application In A Rangeland Chronosequence, Grace Damaschino

Master's Theses

Compost application to rangelands has the potential to sequester carbon (C) and add essential plant nutrients to the soil. The California Department of Food and Agriculture's (CDFA) Healthy Soils Project (HSP) provides financial support to farmers and landowners to implement innovative practices that promote soil health. The CDFA is currently recommending compost application rates of 6-10 tons per acre; however, previous research suggests that degraded soils may require a larger dose of compost to overcome limitations, therefore this recommendation might not meet soil health or soil carbon sequestration objectives. This study examines the compost rate effects on soil health, while …

The Application Of Generative Ai For Sketch-To-Image Conversion, Jeremy J. Kozlowski

Master's Theses

Sketches have historically been the primary way to identify individuals when images are unavailable. Most commonly, this appears in a police investigation, where the police release a sketch to the public in an attempt to find a suspect. However, sketches occasionally do not provide much detail due to the limitations of both the witness and the artist. A poor sketch greatly hinders the public’s ability to identify someone, decreasing the chances they will be found. To improve upon this inefficient way of identifying individuals, we propose a new pipeline that leverages deep generative artificial intelligence models to create detailed images …

“My Pregnant Man Story”: “Bloodchild” As A Means Of Discussing Reproductive Rights, Ashley Lear

Feminist Pedagogy

Restrictions on reproductive health education in Florida have resulted in misinformation and taboos that could be addressed through parallels in science fiction. As Paweł Frelik, University of Warsaw Professor of American Studies, reminds us, science fiction is a “cultural discourse,” in which “fantastic figures such as aliens, clones, and cyborgs are allegories of race, ethnicity, gender, sexuality, able-bodiedness, and other dimensions of individual subjectivity.” Octavia Butler’s short story “Bloodchild” (1995) will be used in this activity to discuss reproductive rights with students in the wake of so many legal challenges to those same rights. Butler, inspired by her own fears …

Williams’ Account Of Positive Obligation And Speciesism: Extending Ashford’S Internal Argument Against Williams, Nathan Bray

Between the Species

In Ethics and The Limits of Philosophy and elsewhere, Bernard Williams presents a formidable objection to utilitarianism. Dubbed the integrity objection, the worry is that utilitarianism is too demanding in requiring agents to abandon their projects in favor of complying with moral injunctions. Elizabeth Ashford (2000) has replied, in part, by arguing that Williams’ account of positive obligation (WPO) is similarly susceptible to exacting burdensome demands on moral agents, such as care for those in emergency situations (pp. 428-431). If these charges of over-demandingness apply to each theory, and if utilitarianism is seen as obligating agents to care for nonhuman …

Hypoxic Incubator: Improving Robustness/Reliability And Demonstrating Physiological Efficacy, Damon Dennis Tan

Master's Theses

The Microphysiological Systems Laboratory aims to develop colorectal cancer tumor models under a hypoxic environment to assess model response to pharmaceutical compounds in vitro. To perform relevant studies, researchers have attempted to use different hypoxic inducing strategies such as a nitrogen pod and hypoxic incubator to recreate in vivo physiological responses to hypoxia. However, studies would be interrupted due to incubator functionality failure. To ensure successful and physiologically relevant studies, I improved and verified the robustness and reliability of a hypoxic incubator previously designed and manufactured in the lab. Through the testing and iterating design processes, I engineered and implemented …

Loving Beyond The Human: Anthropocentric And Anthropomorphic Values In The Loving And Hating Of Nonhuman Animals, Stephanie M. Takata-Struble

Between the Species

I offer an account of the centrality of values to moral experience and the ways in which value disorder characterizes our relationships with nonhuman animals. To do this, I first provide an account of Max Scheler’s phenomenology of values, including the hierarchy of values, and loving and hating as value orientations. Drawing on this account, I map out two value orientations specific to our relationships with animals—anthropocentrism and anthropomorphism. Within these two value orientations, I detail three specific forms of valuation—gustatory, cosmetic, and anthropomorphic substitution—which demonstrate the ways in which people’s naïve love for the nonhuman animal is often, phenomenologically, …

Modeling, Simulation, And Experimental Testing Of A Single-Legged Hopper, John Anthony Bennett

Master's Theses

Legged robots are well-suited for navigating unstructured terrain due to their ability to perform agile dynamic motions. Building on the efforts of Cal Poly's Legged Robotics Group, this project focuses on achieving stable forward hopping with a single legged robot.

A comprehensive model of leg hopping is formulated, with leg dynamics during flight and stance phases derived using Euler-Lagrange equations. During the stance phase, a spring-mass system models the leg-ground interaction. The touchdown and lift-off conditions are formulated mathematically, and state mappings between phases are determined via momentum conservation. A two-phase hybrid controller is designed, incorporating trajectory planning during flight …

Effects Of Extreme Starvation On The Fasting-Adapted Western Rattlesnake (Crotalus Oreganus), Brandon R. Kong

Master's Theses

Ambush-hunting snakes have long been of great interest in the biology of fasting and starvation, as they are adapted to withstand well over a year without taking a meal. Well-justified ethical constraints have limited our understanding of their biology at the limits of these abilities. Unfortunate circumstances, in which the California Department of Fish and Wildlife confiscated over 50 Western Rattlesnakes (Crotalus oreganus) from an animal hoarder that had long neglected them, culminated in the euthanized animals ending up in the hands of our lab. Some of these snakes were extremely starved, being only one-half to one-third of …

Effect Of Enzymatic Pretreatment On Biomethane Production From Olive Pomace, Ningjing Zhong

Master's Theses

In 2023, approximately 2.36 million metric tons of olive oil were produced globally. Olive pomace, a byproduct of the flesh and pits left after olive oil extraction, presents environmental challenges when used as landfill due to its high polyphenol and organic contents, or when combusted due to greenhouse gas emissions. Its potential as animal feed is limited, yet it holds promise for methane production via anaerobic digestion (AD), providing a source of renewable energy. However, the highly crystallized polysaccharides in olive pomace, such as cellulose, hemicellulose, and pectin, impede its conversion to methane, and the high polyphenol content inhibits methanogen …

Development Of An Undergraduate Course On Women In The Design Of The Built Environment, Anahid Behrouzi, Kira Hope Tolman, Paige Van Rossum

Architectural Engineering

The Cal Poly in San Luis Obispo (Cal Poly) Architectural Engineering (ARCE) department has seen significant progress in reaching gender equity as evidenced by recent student enrollment numbers. However, ARCE-affiliated technical and history classes still lack discussion of notable female practitioners or the value of input from women as project stakeholders. This educational shortcoming is likely true at many other civil or structural engineering, construction management, and architecture programs. To address this gap, the authors developed a new 1-credit hour course offered in Spring 2024 to Cal Poly Honors and ARCE students to expose them to the contributions and concerns …

Neo-Aristotelian Friendship And Non-Human Animals: Can I Be Friends With My Dog?, Dustin Sigsbee

Between the Species

“A dog is man’s best friend” is a well-known and widely used phrase, but are we right in thinking that dogs are our friends? If so, do we owe our dogs what we owe our friends? Aristotle recognized three different kinds of friends: friends of utility, friends of pleasure, and friends of virtue. I suggest that dogs can meet the conditions necessary for entering into the first two kinds of friendship, but that there is a potential moral hazard in thinking about our relationship with dogs in these terms. It is unclear whether dogs can meet the more stringent conditions …

Engineering An Injectable Hydrogel With Self-Assembling 3d Vasculature, Kendyl Cohn
