Synthesis, Characterization, And Performance Assessment Of Reusable And Biodegradable Antimicrobial Polymeric Membranes For Aerosolized Pathogen Inactivation And Filtration, Ebuka Ogbuoji

Theses and Dissertations--Chemical and Materials Engineering

Air filtration technology has proven effective in purifying air by trapping particulates which can cause adverse health effects. High Efficiency Particulate Air (HEPA) filters, capable of capturing over 99.99% of PM_0.3, are recommended for critical applications. However, conventional non-woven HEPA filters rely on electrostatic interactions to trap smaller particles, which can deplete over time or after cleaning, reducing filtration efficiency and posing health risks. Additionally, these filters contribute to plastic waste.

This dissertation investigated the feasibility of using flat sheet polymeric membranes fabricated via nonsolvent-induced phase separation (NIPS) as reusable and biodegradable alternatives to commercially available non-biodegradable air …

Long-Term Cardiometabolic Effects Of Preconceptional And Prenatal Opioid Exposure In The Adult Offspring, Nermin Hassan Mohamed Selim Ahmed

Theses and Dissertations--Pharmacology and Nutritional Sciences

Opioid use disorder (OUD), one of the greatest public health threats in the US, requires urgent attention. In 2022, the CDC reported 107,941 overdose deaths, over 70% attributed to synthetic opioids such as fentanyl (FEN). An alarming increase in opioid use disorder (OUD) diagnoses in pregnant people resulted in a 5-fold rise in cases of neonatal opioid withdrawal syndrome (NOWS). This condition elicits sympathetic overactivity, neural hyperexcitability, and a stress reaction characterized by tachycardia and hypertension. Whether prenatal exposure to fentanyl induces cardiovascular dysfunction in the offspring remains undetermined, impeding the timely development of strategies to mitigate OUD-related health risks …

Profiles Of Satisfaction And Frustration Of Undergraduate General Chemistry Students’ Basic Psychological Needs At The Beginning And End Of The Semester, Cara E. Worick

Theses and Dissertations--Educational, School, and Counseling Psychology

The early college years represent an adjustment period characterized by motivational destabilization and academic and career-related uncertainty for many STEM majors (Robinson et al., 2019). Although students who begin college less academically prepared than their peers are at greater risk of struggling in introductory STEM courses, many still struggle in these courses despite adequate academic preparation (Perez et al., 2014). Self-determination theory proposes that motivation, optimal functioning, and psychological well-being occur through the satisfaction, as opposed to the frustration, of three basic psychological needs for autonomy, competence, and relatedness (Ryan & Deci, 2020). Although many studies in educational settings demonstrate …

While trends before, during, and after the pandemic have been extensively studied for common cardiovascular diseases, such as heart …

A 3-Step, Open-Data, Ride-Hailing Ridership Model With Pricing Applications, Richard A. Mucci

Theses and Dissertations--Civil Engineering

Researchers and practitioners studied the effects ride-hailing had in cities before the covid-19 pandemic. Previous research found ride-hailing to produce negative externalities, such as reducing transit ridership and increasing congestion in various cities. Since the pandemic, ride-hailing ridership has nearly recovered to pre-pandemic levels in Chicago. Ride-hailing ridership has grown steadily since the pandemic while a rider’s willingness to share their trip stagnated. Ride-hailing ridership nearly recovering to pre-covid levels in Chicago suggests that transportation planners, and policy makers, will need to continue assessing the impacts ride-hailing trips have in their cities.

Pickup and drop off locations in the Chicago …

An Efficient And High-Throughput Method For The Evaluation Of Mitochondrial Dysfunction In Frozen Brain Samples After Traumatic Brain Injury., Hemendra J Vekaria, Olivia J. Kalimon, Paresh Prajapati, Gopal V. Velmurugan, Patrick G Sullivan

Neuroscience Faculty Publications

Mitochondrial function analysis is a well-established method used in preclinical and clinical investigations to assess pathophysiological changes in various disease states, including traumatic brain injury (TBI). Although there are multiple approaches to assess mitochondrial function, one common method involves respirometric assays utilizing either Clark-type oxygen electrodes or fluorescent-based Seahorse analysis (Agilent). However, these functional analysis methods are typically limited to the availability of freshly isolated tissue samples due to the compromise of the electron transport chain (ETC) upon storage, caused by freeze-thaw-mediated breakdown of mitochondrial membranes. In this study, we propose and refine a method for evaluating electron flux through …

Post-Capture Synthesis Of Images Using Manipulable Integration Functions, Paul Eberhart

Theses and Dissertations--Computer Science

Traditional photographic practice, as dictated by the properties of photochemical emulsion film, mechanical apparatus, and human operators, largely treats the sensitivity (gain) and integration interval as coarsely parameterized constants for the entire scene, set no later than the time of exposure. This frame-at-a-time capture and processing model permeates digital cameras and computer image processing. Emerging imaging technologies, such as time domain continuous imaging (TDCI), quanta image sensors (QIS), event cameras, and conventional sensors augmented with computational processing and control, provide opportunities to break out of the frame-oriented paradigm and capture a stream of data describing changes to scene appearance over …

Two Perspectives On Immigrants In The Labor Market: The Immigration Act Of 1990, Shria Holla

Gaines Fellow Senior Theses

When evaluating the impact of immigration, extant economic literature has overwhelmingly focused on natives and men. The widely accepted methodology in the literature usually segments by education and by experience. Segmenting by education has been found to not be viable for immigrants due to immigrant downgrading, and experience is not conducive for women since it is calculated based on age. Through both an empirical analysis and an ethnography, this study takes the initial steps to include existent immigrants and women in the discussion. The economic empirical analysis evaluates the impact of immigration on existent immigrants, a growing portion of the …

Comparing Corequisite And Prerequisite Models For Supporting Underprepared Students In Higher Education, Sara Hendricks

Theses and Dissertations--Educational Leadership Studies

This dissertation investigates the impact of two prevalent types of developmental education (DE) courses—prerequisite and corequisite—on student retention in higher education. As institutions increasingly address concerns over the academic preparedness of first-year students, many implement remedial education courses to support those who are underprepared (National Center for Education Statistics, n.d.). However, these courses disproportionately affect students of color and often contribute to higher dropout rates (USG, 2021; Bailey & Jaggars, 2016). While previous research indicates that corequisite courses, where students enroll in standard courses with additional academic support, can positively impact retention, there is limited knowledge on their effect on …
