Developing A Semester-Long Project In A Biomechanical Engineering Course To Instill The Entrepreneurial Mindset In The Next-Generation Biomedical Engineering Students, Loren Hedgecock

Biomedical Engineering Undergraduate Honors Theses

Entrepreneurial-Minded Learning (EML) is an emerging pedagogy progressively gaining popularity in the engineering education community. Coincided with project-based learning (PBL), EML illustrates an essential dimension to the instruction of next-generation engineers, equipping them with various perspectives and approaches to relate societal challenges with technical concepts. Nationwide initiatives, such as the Kern Entrepreneurial Engineering Network (KEEN), have developed a learning framework specifically designed to create engineers such as these. The implementation of EML aims to stimulate connections, create value, and ignite curiosity. This study introduced a semester-long project based on these EML skillsets in a sophomore-level biomechanical engineering course. To evaluate …

The Interaction Of Angiotensin I And Ii On Calcified Aortic Valve Cells, Fah Sysavanh

Biomedical Engineering Undergraduate Honors Theses

Cardiovascular diseases affect the older population with limited treatments available. Aortic valve stenosis is a cardiovascular disease in which the aortic valve narrows, causing blood flow constriction and calcification.¹ The only treatment is to replace the valve, which can be costly and lead to other health complications.

The renin-angiotensin system (RAS) is a pathway that helps with maintaining cardiovascular homeostasis. Angiotensin I (ANGI) and II (ANGII) are hormones in the RAS that cause an increase in inflammation, stress, and blood pressure by binding to the Angiotensin Type 1 Receptor (AT1R).¹ Gelatin-based valve thin film (vTF) platforms were fabricated to investigate …

Alternative Fixation Of Venous Valves For Bioprosthetic Applications, Makenzie Kapales

Biomedical Engineering Undergraduate Honors Theses

Venous valve failure allows for the retrograde, or backward, flow of blood into the lower extremities, which leads to Chronic Venous Insufficiency (CVI). CVI infringes upon quality of life through ulceration and can result in death due to Deep Vein Thrombosis (DVT), or blood clots, causing pulmonary embolism. A successful treatment of CVI restores valve function and prevents retrograde blood flow; however, current bioprosthetic venous valves exhibit low patency and high calcification. To improve upon bioprosthetic venous valves and CVI treatment, the University of Arkansas’s Cardiovascular Biomechanics Lab conducts studies with the purpose of comparing the properties and performance of …

Virtual Reality As An Education Tool In Biomedical Engineering, Megan Wilkerson

Biomedical Engineering Undergraduate Honors Theses

Virtual Reality (VR) has become more accessible in recent years, both to experience and to create. Various studies have shown that incorporating VR in an educational setting can yield positive results.

VR videos were implemented in a remote biomolecular engineering laboratory course. 180° VR videos of lab procedures were recorded and viewed by students using a Google Cardboard headset and their smartphones. After viewing all the VR lab videos, students were given a survey to report their experiences. The survey contained questions used to measure …

Sequential Illumination In A Tomographic Microendoscopic Probe For Imaging Tumor Microvasculature, Zachariah Neumeier

Biomedical Engineering Undergraduate Honors Theses

Knowledge of colorectal cancer biology is improving how we approach cancer treatment. Specifically, the tumor microenvironment and abnormal angiogenesis are of particular interest. Optical methods are a prime candidate for research of the tumor microenvironment due to their ability to quantitively assess tissue structure and perfusion in real time. Particularly, the “transport scattering regime” has been identified as a method of obtaining high-resolution images and reflectance spectroscopy data; this light scattering regime has been demonstrated compatible with endoscopic imaging systems. In this study, a proof-of-concept optical imaging system is presented, capable of resolving absorbers within scattering turbid media using a …

(Re)Fashioning Gender: Dress As Embodied Feminist Critique In Modernist Women’S Writing, Lauren Elizabeth Sperandio Phelps

English Dissertations - Archive

In this dissertation I examine early twentieth century women writers’ use of fashion as a mode of critiquing gender, race, and class oppression. Through close reading of the novels of Nella Larsen, Edith Wharton, Anzia Yezierska, Radclyffe Hall, and Virginia Woolf, I explore how fashion in these works functions to emphasize elements of identity formation and conditioning. I argue that by taking up fashion as a tool for critique women writers were able to simultaneously challenge oppressive social structures as well as appraisals of women as unfit for serious analysis or literature. If fashion is considered trivial, then using it …

A Teacher Goes To School: A Retrospective Analysis Of Pedagogical Insights On Secondary Writing Instruction, Karen Stelter Otto

English Dissertations - Archive

High school English teachers are familiar with current masters in the field (Kittle, Burke, Gallagher), but are not familiar with the scholarly literature on the topics of composition. Although helpful, these professional development books offer examples of quality lessons for helping students become stronger and more confident writers, but rarely do these books address the research that supports these findings. This dissertation is a retrospective study and analysis of the pedagogical insights on secondary writing instruction that I learned through my doctoral journey. I examine five areas of interest: peer review, teacher review, service-learning, grammar, and grading. I analyze the …

Making Selves As We Make Scholars: The Many Uses Of Life Writing In College English, Lindsey Rose Gendke

English Dissertations - Archive

This dissertation addresses the perennial question, for both new and more seasoned English professors, “What should we teach in English?” In composition, “What types of writing should we teach?” And in literature, “what literature, and which authors, should we read?” In the current age where teachers are concerned with promoting diversity, equity, and inclusion, perhaps these questions are more relevant than ever. Thus, employing Wayne Booth’s rhetorical stance as my theoretical frame, I inquire 1) what are the most pressing needs of traditional-age college students, and 2) what theories and teaching strategies uncovered in recent English studies have the potential …

Bioengineering Dissertations - Archive

Decision-making is one of the most critical activities of human beings. Various studies have investigated the brain responses to a variety of decision tasks by deploying the EEG data. The first aim of my dissertation was to investigate the neurocognitive mechanisms and correlations across multiple subjects when people make risky economic decisions. A decision-making task was designed based on the newsvendor problem (NP) with two scenarios: low-profit margins (LM) as the more challenging scenario and high-profit margins (HM) as the less difficult one. The EEG signals were acquired from healthy humans while subjects were performing the task. The Correlated Component …

Engineering Enzymatic Pathways In The Gut Microbiome To Control Dietary Isoflavone Metabolism, Lenaiya Allisen Kydd

Bioengineering Dissertations - Archive

ABSTRACT: Observing how plasmids persist within the gut can help us understand how newly introduced genes are transmitted within the gut microbiome. I sought to determine the persistence of genetic constructs introduced to the murine gut and then develop our own genetic system to be delivered to the gut to engineer the microbiome in its ability to convert certain dietary isoflavones. In my initial experiments, mice were given bacteria containing a genetically engineered plasmid and were examined for the persistence of the plasmid in the gut. I found long-term persistence of the plasmid in the gut for up to 2 …

Lung infections, especially lower respiratory tract infections and their associated pneumonias, are one of the leading causes of death, accounting for more than 4 million fatalities every year worldwide. Bacterial pathogens are involved in many lower respiratory tract infections including emerging antibiotic resistant respiratory pathogens such as methicillin-resistant staphylococcus aureus (MRSA). Current interventions for MRSA lung infections include systemic antibiotic treatments for an extended period leading to various side effects such as acute kidney injury, nephrotoxicity, and so on. To overcome these limitations, the goal of this dissertation research is to develop a drug delivery system, which includes pathogen-specific drug-loaded …

Parental Involvement And Satisfaction: A Comparative Study Of High-School Charter Schools And Traditional Public Schools, Nicholas Thompson-Davis

Educational Leadership & Policy Studies Dissertations - Archive

The purpose of this study is to examine parents’ levels of satisfaction with school choice by comparing charter and traditional public schools at the secondary level. The main assumption of the study is that parental satisfaction with school choice is related to parental involvement with children’s education and their views of school-home communication. The study is guided by Bourdieu’s theory of capital to interpret parental involvement efforts and their assessment of school-home communication as ways to acquire social capital for themselves and their children. Epstein’s framework of parental involvement allows for operationalizing the concept with respect to school and out-of-school …

The Medicalization Of Communication: An Analysis Of The Policies And Educational Practices Surrounding Patient And Physician Interaction, Ramona Jewelmaria Dorough

Educational Leadership & Policy Studies Dissertations - Archive

This dissertation explores the medicalization domains through three studies to assert that communication exists in all facets of the patient- physician relationship. The first study is a policy analysis that examines the institutional domain through policies and educational standards created in the medical community that dictate the importance of communication. The second study examines medical students' level of clinical empathy using the Jefferson Scales of Empathy. The second study ties to the conceptual domain of the medicalization of communication, showing the creation of terminology (i.e., clinical empathy, clinical communication) helps uniquely identify and measure empathy through communication. The third study …

Development Of Algorithms To Analyze Electrogastrography (Egg) For Neonatal Gastrointestinal Development And Electroencephalography (Eeg) For Effects Of Led-Based Pre-Frontal Light Stimulation, Akhil Mahendra M Chaudhari

Bioengineering Dissertations - Archive

Algorithm development, and biological signal processing are the key components for new applications of successful medical diagnosis that can provide physiological and functional information to better understand human condition for either patients with certain diseases or healthy human beings. Neuroimaging tools, such as functional near infrared spectroscopy (fNIRS), and electrogastrography (EGG) have been used to investigate the gut maturity in diseased and healthy state; and electroencephalogram (EEG) have been used to investigate brain functions in response to neuromodulated or task-based interventions. Accordingly, my dissertation focused on algorithm development and signal processing for two major topics: (1) to outline EGG response …

Hydrodynamic Forces On Stream-Crossing Bridges – Consideration Of Flow Parameters, Bridge Geometry, And Debris, Shah Md Imran Kabir

Civil Engineering Dissertations - Archive

ABSTRACT: This thesis examines the interaction of flood flow with bridge superstructures by considering the effects of the flow parameters, bridge geometry, debris, and bridge substructures. The hydrodynamic forces are expressed by using force and moment coefficient charts to portray the effect of bridge submersion, bridge position with respect to the channel bed, flood velocity, and bridge geometry. Of the 580,000 bridges in the United States, 83% span streams and rivers that may subject them to floods and debris loads. Although bridges are designed to withstand hydrodynamic forces, the most frequent causes of failure are attributed to hydraulic events, including …

Performance Of Density Estimators In Additive Measurement Error Models Based On Right Censored Data, Hrishabh Khakurel

Mathematics Dissertations - Archive

In the deconvolution problem for right censored data, one is interested in estimating the density of a contaminated variable X when X satisfies Z= X+ E, where E is a measurement error with a known distribution, and the observable variable Z is right-censored. Zhu, Sun, Khakurel, and Wang (2021) applied the Inverse Probability of Censoring Weighted Average method and derived the estimators of the unknown density of X. In this study, we evaluate the performance of the density estimators both in theory and in simulation. We derive the theoretical upper bounds for Mean Squared Error (MSE) of the estimator and …

Investigating Hybrid Cyclic/Linear And Linear Peptides As Vehicles For Nucleic Acid Delivery, Abdulelah Alhazza

Pharmaceutical Sciences (MS) Theses

Small interfering RNA (siRNA) and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated Protein 9 (Cas9) are advanced biotechnological approaches that have been able to temporarily downregulate gene expression through post-transcription RNA interference or permanently knockdown a protein via creating a mismatch in DNA, respectively. Nucleic acids are anionic and hydrophilic molecule, which cannot enter the cell through passive diffusion and/or interaction with the cell membrane. Cell-penetrating peptides (CPPs) offer a unique carrier for nucleic acid delivery, where positively charged components of CPP bind to the negatively charged nucleic acid and the hydrophobic components enhance the interaction with cell membrane, and …

Developing A Prototype Of A Playfulness Toolkit, Hanneke Hovels

Creativity and Change Leadership Graduate Student Master's Projects

Playfulness is the ability to reframe situations, seeing new possibilities. A playful mind-set increases our mental flexibility, resilience, empathy, and our overall well-being. Unfortunately, growing up most of us lose part of our playfulness. How can we facilitate adults to live a (more) playful life? To ignite playfulness in adults’ lives, we first have to raise awareness for the benefits of playfulness, and then help people to develop a playful mind-set and integrate playfulness into their lives. In this project I combine my knowledge of creativity and playfulness with my experience in service and behavior design. I developed a prototype …
