Anaerobic co-digestion of acid whey and sewage sludge for enhanced renewable energy production

Creator:: Cole, Emerson
Abstract:: Acid whey is the largest byproduct of the dairy industry but to date has few useful applications and is frequently discarded as a result. However, acid whey has a high carbon content, making it a suitable co-substrate for anaerobic co-digestion with raw sewage sludge. The synergistic effect of co-digestion has...

Light quality manipulation for the solvent extraction of phycocyanin from Oregon freshwater cyanobacteria

Creator:: Gregor, Katelin
Abstract:: Phycocyanin, a photosynthetic pigment-protein complex produced by cyanobacteria, has critical value in the medical field at high purity. Costs associated with the extraction of this pigment are high, emphasizing the importance of optimal growth conditions. The aim of this study was to investigate potential commercial producers of phycocyanin by evaluating...

Changes in Microbial Extracellular Enzyme Activity in Pacific Northwest Old-Growth Forest Soils After Wildfire

Creator:: Hughes, Abby
Abstract:: The soil microbiome drives nutrient transformation in forest soils and plays a critical role in the carbon (C) cycle of these ecosystems. Wildfires cause significant disturbance to ecosystems and are known to alter C sources available to microbes in forest soils. Summer wildfires in the Pacific Northwest are of growing...

The Stability, Toxicity, and Reactivity of Zero Valent Iron Nanoparticles

Creator:: Bulovsky, Hannah G.
Abstract:: Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...

A Proposed Treatment System for the Remediation of Landfill Leachate Using Algae

Creator:: Myers, Shanna Grace
Abstract:: Landfill leachate is a complex wastewater that contains high levels of ammonium (often over 250 ppm) and trace heavy metals (usually under 0.2 ppm). Microalgae have been shown to inexpensively and effectively treat wastewaters containing high loads of organics and nutrients, as well as adsorb metal ions. This thesis focuses...

Chronic Toxicological Effects in Daphnia magna from Exposure to PMMA Nanoplastics

Creator:: Brown, Hans
Abstract:: Plastic pollution is an ever-increasing environmental threat. As large-scale plastics break down to form nanoscale plastics, it is essential to investigate their effects on freshwater ecosystems. With many plastic nanoparticle (NP) studies favoring the effects of common polystyrene (PS) plastics, a gap is formed for other common plastic types like...

Prescription Drug Abuse among 12 to 17 Year Adolescents in the United States

Creator:: Paralkar, Manali P.
Abstract:: This study examines issues related to prescription drug abuse among 12 – 17 year olds in the United States; namely, the physiological effects of prescription medications, current treatments, and prevention methods. The following research questions are addressed: 1) What factors influence and promote the growing prevalence of prescription drug abuse...

Circadian Clock Disruption via Exposure to Extended Light at Night (LAN) Alters Epigenetic Expression of CKI Genes in the Murine Mammary Gland

Creator:: Rogers, Zackry L.
Abstract:: Breast cancer is a leading cause of cancer deaths among women, with an estimated 12.4% of American women diagnosed with this tumor type. Evidence suggests that exogenous disruptors can exert epigenetic changes leading to aberrant gene expression, shifting the cellular balance toward oncogenesis. While chemical pollutant exposure is well-studied, light...

An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

Comparing the autoignition performance of chemical kinetic models for toluene using data extracted from the literature

Creator:: Mayer, Morgan
Abstract:: Real transportation fuels contain a wide range of hydrocarbon species, and this complexity poses challenges for modeling. Surrogates with a simpler blend of hydrocarbon reference fuels can approximate the physical and chemical characteristics of real fuels and enable practical simulation of the reacting flows that occur in engines and combustors....
