Physical Properties Of Aqueous Aerosols In The Presence Of Oxalic Acid, Felicia Lutz
Physical Properties Of Aqueous Aerosols In The Presence Of Oxalic Acid, Felicia Lutz
Celebrating Scholarship and Creativity Day (2018-)
Different compounds in atmospheric aerosols absorb water (deliquesce) and release water (effloresce) at different levels of humidity. This can affect the chemistry of atmospheric aerosols as well as the formation of clouds and movement of water vapor in the sky. While there has been previous research on deliquescence of salts, the results of compounds mixed with organics are of more interest as the composition of aerosols are better understood. Organics can impact other physical properties of liquid aerosols like surface tension. In this research, the deliquescence relative humidity, efflorescence relative humidity and surface tension was determined for common salts found …

Getting Your Master's, Is It Worth It?, Vy Le, Madyson Schreifels

This project uses a differential equation model to evaluate whether earning a master’s degree is financially worthwhile. Using UC Berkeley’s Master of Computer Science program as a case study, we modeled student loan repayment and compared long-term earnings between bachelor’s and master’s degree holders. The model predicts monthly loan payments and estimates the break-even point where the higher salary from the master’s degree outweighs the total investment cost. Results suggest that the degree becomes financially beneficial after approximately 15 years.
Supercritical Fluid Extractions Of Organic Compounds For Chemistry 202 Laboratory, Avery Polipnick, Autumn Larson
Supercritical Fluid Extractions Of Organic Compounds For Chemistry 202 Laboratory, Avery Polipnick, Autumn Larson
Celebrating Scholarship and Creativity Day (2018-)
Supercritical fluid extractions are a green chemistry technique that is used to isolate nonpolar compounds, without the use of solvents that are harmful to the environment. Compounds reach their supercritical point which is found above their critical temperature and pressure causing them to be in a state between liquid and gas phases. Carbon dioxide in its supercritical fluid form acts as a solvent. This study investigates how a supercritical carbon dioxide extraction can be incorporated into the Chemistry 202 Laboratory curriculum at the College of Saint Benedict and Saint John’s University. Initial conditions for this extraction were previously determined. The …

Library Faculty Publications & Presentations
The upcoming Next Discovery Experience (NDE) introduces major changes to how users search, interpret information, and navigate Primo. Preparing for NDE is an opportunity to center the diverse students and faculty who rely on discovery systems every day, ensuring that their lived experiences, accessibility needs, and research practices guide interface design, configuration, and communication. This session presents a consortial approach to NDE readiness that positions students and community members as partners in the development process. We describe strategies for creating ethical and rigorous UX research workflows that include IRB approval, purposeful recruitment, accessible study design, and clear documentation on the …
Redefining Certainty: Non-Euclidean Geometry And Theology Transformation Throughout The Intellectual Unrest Of The Early 1800s, Luke Bensinger
Redefining Certainty: Non-Euclidean Geometry And Theology Transformation Throughout The Intellectual Unrest Of The Early 1800s, Luke Bensinger
Honors Theses
To bridge the gap between mathematics and theology, it is necessary to explore their intersection and challenge the notion that these fields are incompatible. This study focuses on the 19th century, a period when non-Euclidean geometries emerged and disrupted mathematical certainty, while Protestant theologians such as Barton W. Stone and Alexander Campbell grappled with Calvinism and shifting theological perspectives. By analyzing mathematicians studying geometry, such as Gauss, Lobachevsky, and Riemann, this research examines how both disciplines balance change with enduring truths.
Analysis Of The Flavonoid Composition Of Honey Using High-Performance Liquid Chromatography, Bryce Phillips
Analysis Of The Flavonoid Composition Of Honey Using High-Performance Liquid Chromatography, Bryce Phillips
Honors Theses
Honey is a naturally occurring substance that has a complex composition including compounds such as flavonoids, that contribute to potential health benefits. Quantitative analysis of flavonoids in honey can be challenging due to their similar structural characteristics, matrix effects, and chromatographic peak separation issues. This study aimed to establish calibration curves for five flavonoids–kaempferol, luteolin, chrysin, myricetin, and quercetin– to estimate their concentrations in five honey samples from varying geographic origins. Liquid-liquid extraction was used to isolate the flavonoids from honey. High Performance Liquid Chromatography was utilized to establish calibration curves and analyze honey samples. The calibration curves assembled demonstrated …

Warming, sea-level rise, and changing herbivory patterns are affecting ecosystem processes in northern coastal soils, including carbon and nitrogen cycling, although their combined effects are poorly understood. We studied the impact of these changes in a full-factorial microcosm experiment using four distinct soil types from the Yukon-Kuskokwim Delta of western Alaska. Soil was collected from three coastal wetlands, which differ in flooding frequency and use by migratory geese, and one rarely-flooded upland tundra used by geese in late summer. Microcosms containing these soils were incubated for 16 weeks at 10°C or 18°C, with or without three short-term floods, and with …
