In-Vitro Testing Of Light Wavelength To Detect Clots In Neonatal Extracorporeal Membrane Oxygenation Circuitry, Amanda Holmes

Dissertations and Theses (Open Access)

Background: Neonates requiring extracorporeal membrane oxygenation (ECMO) are at high risk for thrombotic complications, which contribute substantially to morbidity and mortality. Current circuit surveillance methods rely on intermittent visual inspection and indirect laboratory markers, both of which often detect thrombosis only after clinically significant progression. Optical approaches offer a non-invasive alternative for earlier clot visualization, yet the influence of illumination wavelength on detection performance under realistic ECMO conditions remains incompletely characterized.

Methods: This study evaluated wavelength-dependent clot detection performance in a controlled in-vitro neonatal ECMO circuit model using a portable imaging prototype designed to emulate bedside workflow. Twelve independent ECMO …

Using a Vygotskian framework with Cultural-Historical Activity Theory (CHAT) and Knowledge Structures (KS), the study examines how teachers navigate systemic contradictions and how these tensions influence their professional identities.

Using an interpretivist approach, data were collected via semi-structured interviews, a focus group, and a researcher’s journal from six experienced bilingual educators. Thematic analysis reveals profound structural fractures within the activity system: a primary contradiction between …

Modeling Causal Interactions Across Brain Functional Systems For Population-Specific Disease Analysis, Alissen Moreno

Theses and Dissertations

Functional brain connectivity provides critical insight into neural mechanisms underlying neurodegenerative and affective disorders. Traditional neuroimaging studies rely on undirected or region-specific connectivity measures developed predominantly using racially homogeneous cohorts, limiting fairness and generalizability across diverse populations.

We propose a population-aware framework modeling directed causal interactions across large-scale brain functional subnetworks. Resting-state fMRI data from the HABS-HD cohort were used to construct subject-level causal connectivity matrices via ICA-LiNGAM, aggregated into interpretable system-level hyper-connectomes representing interactions among eleven canonical brain subsystems. These features trained nonlinear models for Alzheimer’s disease stage classification and trait worry prediction.

Results demonstrate that MLP models outperform …

Enhancing Walleye (Ogaa) Recruitment: Evaluating Assisted Reproduction As A Mitigation Strategy, Douglass Keiser

Biology Graduate Theses

Over the past several decades, cold- and cool-water fish populations across the Upper Midwest, including Minnesota and Wisconsin, have shown troubling signs of decline. Among the most affected is the walleye/Ogaa (Sander vitreus), a species deeply embedded in the ecological balance, cultural identity, and economic vitality of the region, and central to the lifeways, treaty-reserved rights, and resource stewardship of Tribal Nations, including Ojibwe communities across the Upper Midwest. Despite ongoing stocking efforts and harvest regulations, many lake systems have experienced persistent declines in natural recruitment, prompting resource agencies to investigate the underlying causes. One such system is …

Biodiversity Risk And Firm Valuation: Regional Heterogeneity And Value-Chain Exposure In Global Capital Markets, Madelein Wentzel

Doctoral Dissertations (DBA)

This study examines whether biodiversity-related risks are priced in global equity markets and whether that pricing varies across regions, using a cross-sectional sample of more than 10,000 globally listed firms with biodiversity and financial data drawn from the fourth quarter of 2025. Consistent with a regional heterogeneity hypothesis, the results show that biodiversity risk is significantly negatively associated with firm valuation in developed markets such as the United States and OECD countries, while the relationship is weaker, insignificant, or even positive in certain emerging regions including Latin America and the Middle East and Africa. The analysis further distinguishes between value-chain …

Evaluation Of Palm Oil As An Ingredient In Finishing Beef Cattle Diets On Performance, Carcass Characteristics, And Meat Quality, And The Composition Of Spayed Heifers To Intact Heifers Fed Melengestrol Acetate On Feedlot Performance And Carcass Characteristics, Tate S. Johnson

Department of Animal Science: Dissertations, Theses, and Student Research

Heifers represent a large proportion of cattle placed in feedlots, making pregnancy management an important consideration for maintaining performance and carcass value. Melengestrol acetate (MGA) is commonly included in feedlot diets to suppress estrus and prevent pregnancy in intact heifers during the finishing period. Alternatively, spaying has historically been utilized as a management practice to allow heifers to graze alongside breeding cattle without the risk of pregnancy. Despite its historical use, there is limited contemporary research comparing the growth performance and carcass characteristics of spayed heifers with intact heifers managed with MGA under modern feedlot conditions. Therefore, a commercial study …

Reimagining The Canon: A Paired-Text Framework For Student Engagement In Secondary Ela Classrooms, Jannelle Christine Kay Brawner

Masters Projects

Literary engagement correlates to academic success, yet many schools across the nation struggle to engage their scholars meaningfully with traditionally taught canonical literature. The classrooms impacted most by this concern are secondary language arts classrooms. This disengagement can be attributed to a lack of student autonomy in selecting texts, low-interest topics, and an absence of relevance to student identity. As a result, schools are reporting underdeveloped reading comprehension skills, motivation, academic achievement on a variety of classroom and state-mandated assessments, and a sharp decline in critical thinking skills. This project emphasizes the importance of using high-interest paired-text lessons built into …

The Impact Of Play-Based Learning In Early Education, Stefani Merchant

Masters Projects

The increasing emphasis on academic achievement in early childhood education has contributed to a decline in play-based learning. This decline has raised concerns about its impact on children’s overall development. This project examines play-based learning as a developmentally appropriate approach that supports cognitive, social-emotional, language, and self-regulation skills in preschool and kindergarten students. Supported by the theories of Jean Piaget and Lev Vygotsky, the project explores play as a continuum consisting of free play, guided play, and playful learning. With each form of play, there are varying levels of teacher involvement. A review of current research highlights both the benefits …

Low-Abundance And Fragmentary Helicobacter Pylori Dna Detected In Phenotypically Negative Gastric Biopsies Using Targeted Sequencing, Fabien Mbaya-Tshibangu, Alain Cimuanga-Mukanya, Evariste Tshibangu-Kabamba, Nadine Kayiba-Kalenda, Tressy Kalenga-Ngomba, Patrick Ngoma-Kisoko, Gunturu Revathi, Junko Akada, Benoît Mbiya-Mukinayi, Augustin Tshibaka Kabongo

Pathology, East Africa

Accurate detection and monitoring of antimicrobial resistance (AMR) in Helicobacter pylori mainly rely on phenotypic methods and culture, which can sometimes fail when bacterial load is low or after recent treatment. We investigated whether gastric biopsies classified as H. pylori-negative by standard diagnostic techniques still contain detectable bacterial DNA, including regions linked to AMR, and assessed whether selected DNA fragments can mediate allelic exchange in vitro. Gastric biopsies from 46 dyspeptic patients in the Democratic Republic of the Congo (including 23 phenotypically positive and 23 phenotypically negative individuals) were analyzed using long-read amplicon sequencing of seven resistance-associated loci, selective whole-genome …

Optimized Ultrasound Imaging Of Phase-Change Nanodroplets, Charles R Dyall, Dmitry Nevozhay, Andy Liu, Trevor M Mitcham, George J Lu, Konstantin V Sokolov, Richard R Bouchard

Faculty, Staff and Student Publications

Phase-change nanodroplets (PCNDs) continue to generate significant research interest due to their potential to extravasate into tissue, to be targeted for molecular imaging and drug delivery, and to undergo an induced phase-change to "activated" microbubbles (MBs) for ultrasound (US) imaging. To accurately quantify molecular markers, however, one assumes a consistent proportion of PCNDs in a region of interest (ROI) are stably activated and imaged. Herein we present a framework for developing a diagnostic sequence that is optimized for PCND activation uniformity, contrast, and acquisition time. To develop this framework, activation was examined at three scales of increasing complexity: single, adjacent, …
