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 …

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 …

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 …

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 …

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 …

Faculty Publications

This paper discusses the application of acoustic Doppler current profilers (ADCP) for the quantification of transport of water and the underlining physical mechanism. The transport of water through estuaries and tidal inlets is affected by tide, river flow, and wind. It is often assumed that wind effects in such systems are negligible unless under severe weather conditions. This study compares the ADCP-measured flows across a tidal inlet under weak wind conditions in late spring and those after the passage of an atmospheric cold front in winter. The Barataria Pass is a major inlet connecting Barataria Bay and northern Gulf of …

Worth A Shot: Encouraging Vaccine Uptake Through “Empathy”, Dr. Jody Lyneé Madeira

Vanderbilt Journal of Entertainment & Technology Law

Pro- and anti-vaccine organizations and individuals have frequently invoked empathy as a strategy for increasing uptake of COVID-19 precautions, including vaccinations. On one hand, vaccine supporters deployed empathy to defuse conflict, prioritize safeguarding the collective welfare, and avoid government mandates. On the other hand, vaccine opponents used empathy to emphasize the alleged individual effects of pandemic precautions, mobilize public voices, and stress the importance of medical freedom in policy-making contexts.

This Article first defines empathy and reviews empathy scholarship, paying particular attention to its relationship with narrative and the contexts where empathy can be difficult or dangerous. It then applies …

Improved Method For Testing Integrity Loss Of Wells With Sustained Casing Pressure, Mohammad Kazemi, Andrew K. Wojtanowicz

Faculty Publications

The pressure bleed-down/build-up (B/B) testing is enforced by the Bureau of Safty and Environmental Enforcement (BSEE) regulations in the US for gas-leaking wells with recurrent casing head annular pressure dubbed “Sustained Casing Pressure” (SCP). The bleed down test involves bleeding the pressure with a needle valve. Once the pressure reached to zero or stabilized, the valve is closedand a 24-h pressure monitoring starts. Analysis of the tests mandated by regulations involves merely a qualitative assessment of the low or high level of environmental risk measured by leak size. A quantitative analysis—based on mathematical models—has been already proposed and used for …
