Biochar-Derived Ethylene Scavengers For The Preservation Of Bananas, Morgan Samson

Theses

Ethylene regulates the rapid ripening of numerous climacteric fruits (e.g., banana, tomato, mango, and avocado). Minimization of ethylene formation and action in fruits during harvest or at any stage along the supply chain has become an important approach to prolong storage periods and minimize postharvest losses. Active packaging with ethylene scavengers has been proven to extend the shelf life of climacteric fruits; however, a cost-effective and sustainable solution is needed. Biochar-derived ethylene scavengers offer a promising approach to minimize postharvest losses, along with the valorization of abundant organic residues. This study produced and characterized biochars from two different feedstocks (i.e., …

Valorisation Potential Of Microalgae As A Sustainable Source Of Lipids And Health Promoting Compounds, Bozena Mccarthy

Theses

The transition toward a circular bioeconomy requires sustainable strategies for managing and valorising food industry effluents while reducing reliance on environmentally damaging raw materials such as palm oil, which is associated with deforestation, biodiversity loss and greenhouse gas (GHGs) emissions. Microalgae represent a promising platform for converting nutrient rich industrial by-products into biomass and high-value compounds for food, nutraceutical and bio-based applications. Dairy processing generates large quantities of whey, creating environmental challenges due to its high organic load. Improved whey treatment and valorisation strategies are therefore essential for enhancing sustainability in food production systems. In this study, the biomass productivity …

Confederate Women In The Field Of Nursing And Their Impact On Southern Women’S Roles In Society, Laura Leigh L. Prater

Theses

During the Civil War, Confederate women had the opportunity to go to work as nurses. The majority of these women had never been allowed to take on roles beyond the domestic sphere in antebellum society.  Despite most of these women having limited medical training, they developed an expertise in nursing, extraordinary organization skills and gained respect for their achievements.  Their achievements proved that women were able to do far more than many in the South believed prior to the war.  This paper will show how the demands of war opened doors of greater opportunity for women in the South for …

Edvard Munch And The Feminine Sublime, Saralyn Goodspeed

Theses

This paper explores the theory of the sublime in relation to Edvard Munch’s depictions of women. Departing from the common view that Munch was simply anxious about the “New Woman” that emerged in the late nineteenth-century, I argue that Munch’s conflicting emotions regarding women were sublime in nature, rooted in his childhood relationship with his mother. A formal analysis is conducted on three of Munch’s works: Inheritance (1897), Three Stages of Woman or Sphinx (1894), and Madonna (1895). These analyses link Munch’s representations of women to a maternal sublime.

Study Of Global Panel Of Soybean Accessions For Nitrogen Use Efficiency Using Association Mapping, Rita Bhandari

Theses

Soybean (Glycine max [L.] Merr.) is a leguminous crop valued for its high protein, oil content, and other essential nutrients. Global production has significantly increased, with Brazil, the United States, and Argentina being the leading producers. In the U.S., Illinois, Iowa, and Minnesota rank as the top soybean-producing states. Nitrogen (N) is a predominant nutrient required for optimal soybean growth and productivity, particularly in high-yielding varieties. While biological nitrogen fixation and soil mineral N supply part of the plant’s N requirement, synthetic fertilizers are commonly used to meet the remaining demand. However, only 30–50% of applied N is taken up …

Evaluation Of Otolith Microchemistry For Identifying Walleye Stocked As Fry Or Fingerlings, Joshua Fluur

Theses

Walleye (Sander vitreus) is a popular sport fish whose populations are often supported by maintenance or supplemental stocking, with most fish stocked as fry, fingerlings, or advanced fingerlings. Evaluation of stocking efficacy is important to inform decisions regarding fish stocking rates and sizes and allocating hatchery fish to locations where maintenance or supplemental stocking is most needed. Several types of artificial tags or marks have been proven useful in the identification of stocked fish, but they often have various drawbacks. Natural chemical markers in otoliths offer several advantages compared to conventional tags or marks and can be used to identify …

Deep Reinforcement Learning-Based Equitable Post Disaster Resource Allocation Incorporating Social Vulnerability, Trevor John Mogaka

Theses

Prior Deep Reinforcement Learning (DRL) approaches frame post‑disaster recovery as a sequential decision-making problem over infrastructure elements, using graph-based system models and resilience-oriented rewards. This thesis builds on an existing DRL framework by introducing a modified CDC Social Vulnerability Index (mCDC-SVI), developed using Max-min scaling, to quantify social vulnerability.A synthetic interdependent infrastructure testbed is divided into four socio‑economic regions using federal poverty and SNAP eligibility guidelines. The DRL simulation and Deep Q‑Network architecture are retrained under a multi-objective reward function that is efficiency-equity weighted (α:β). Agents are evaluated across unconstrained and constrained budget scenarios to examine how varying α and …

Development Of A Survey For Assessing Women’S Perceptions Of Weight-Related Side Effects Of Hormonal Contraceptives, Ayla Mae Laro

Theses

Background —Hormonal contraceptives (HCs) are widely used among reproductive-age women, yet concerns about weight gain remain common and are frequently cited as a reason for dissatisfaction or discontinuation. Dissatisfaction and discontinuation of HCs can lead to unintended pregnancy—a serious health concern in the United States. Existing research has largely focused on objectively measured weight change as a secondary outcome rather than on perceptions of weight-related side effects, and no validated tool currently assesses these perceptions. Additionally, studies have historically failed to include women with overweight and obesity. This cross-sectional mixed-methods study developed and face-validated an online survey measuring reproductive-age women’s …

Inequality And Well-Being, Sarah E. Boslaugh

Theses

Human well-being has been a topic of interest to philosophers at least since the time of Aristotle, and well-being has also been a core concern of social scientists since the birth of the discipline in the late 18^th century. Some theories of well-being include economic inequality as a factor, and multiple ways to measure this factor have been developed; as with well-being, there is no single best measure of economic inequality and the choice of which measure to use may be based on both theoretical and practical reasons. I argue that income inequality should always be included as a …

Comparative Evaluation Of Five Bacterial Strains For The Fermentation Of Camel Milk, Sifatun Nesa Ali

Theses

In this study, the comparative fermentation performance of lactic acid bacteria Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus, Lb. helveticus, Lb. casei, and Lactiplantibacillus plantarum in Camel Milk (CM) and Bovine Milk (BM) was investigated. Fermentations were carried out at 42°C for 48 hours, and was monitored through bacterial growth, titratable acidity, pH evolution, proteolytic activity, microstructural properties, and rheological characteristics. Although comparable bacterial viability was observed in CM and BM, acidification kinetics varied significantly between CM and BM (p < 0.05). Proteolysis was significantly higher in fermented CM than in BM (p < 0.001), with consistently greater o-Phthalaldehyde Assay (OPA) values in CM across all strains during fermentation (p < 0.001). Scanning electron microscopy revealed more porous, loose protein matrices in fermented CM than in BM, which supports the rheological results showing weaker gel networks and lower rheological strength in fermented CM. Among the tested bacteria, Lb. casei demonstrated superior adaptability, enhanced viability, balanced acidification, and favorable rheological properties in both milks. Overall, the results of this thesis demonstrate strain-specific fermentation responses and support the possible suitability of different starter cultures for improving the technological performance of fermented camel milk products.

Impact Of Oxidative Stress On Mapk Signaling In Human Pancreatic Ductal Cell Line, Alexis Fink

Theses

The main processes linked to diabetes (type 1 or type 2) and obesity are impaired insulin production and glucose intolerance. The imbalance between antioxidant defense systems and oxygen-reactive species are known as oxidative stress. Understanding oxidative stress and its substantial effects on diabetes is crucial. Reactive oxygen species (ROS) can activate mitogen-activated protein kinases (MAPKs). We hypothesize that altered MAPK phosphorylation and hence downstream signaling is associated with changes in oxidative stress in the human pancreatic duct epithelial cell line (H6C7). While H6C7 cells are often engineered to be cancerous precursors, the natural phenotype of these cells and their expression …

Effects Of Energetic State On Male Mating Preferences In Poeciliid Fishes With Differing Mating Strategies, Katherine E. Taylor

Theses

Reproduction is energetically costly, making condition (i.e., energetic state) a potential factor in shaping reproductive behavior. However, its role in male mate choice remains largely unexplored. Here, we investigate condition-dependent effects on male mate choice in two species of Poeciliids: one coercive species (Gambusia affinis) and one courting species (Xiphophorus hellerii). Diet treatments were used to manipulate male and female conditions, and male preferences were assessed in dichotomous-choice tests using animated female stimuli. X. hellerii males showed a preference for high-condition females, whereas G. affinis males showed no overall net preference. Diet influenced preference in G. affinis, with high-fed males …

Caring For Your Heart During Survivorship After Pediatric Cancer: A Visual Education Guide On Chemotherapy-Induced Cardiotoxicity, Bryona Rose Hamilton
