Carbon nanotubes are the subject of intense interest in virtually every field, from medicine to
nano-scale electrical components. Multi-walled nanotubes exhibit a strong nonlinear response
to high-field strength terahertz radiation. This research uses terahertz pulses with field strength
exceeding 1 MV/cm generated by means of optical rectification utilizing a lithium...
Objective: To examine the pricing trajectories in the United States of disease-modifying therapies (DMT) for multiple sclerosis (MS) over the last 20 years and assess the influences on rising prices.
Methods: We estimated the trend in annual drug costs for 9 DMTs using published drug pricing data from 1993 to...
Mycobacterium avium subsp. hominissuis is an opportunistic pathogen that is associated with biofilm-related infections of the respiratory tract and is difficult to treat. In recent years, extracellular DNA (eDNA) has been found to be a major component of bacterial biofilms, including many pathogens involved in biofilm-associated infections. To date, eDNA...
Pseudomonas aeruginosa is a gram-negative nosocomial pathogenic bacterium known for its resilience against antibiotics. The bacterium infects over 50,000 patients each year in the United States, with 13% of reported cases involving multi-drug-resistant strains of Pseudomonas. This research discovered several fungal natural products with promising activity against Pseudomonas aeruginosa. The...
This thesis explores the process of the creation of TEDxOregonStateU, a TEDx event held on the Oregon State campus on February 12, 2015. TED Conferences, created to share “Ideas Worth Spreading”, created the TEDx Program as a platform to allow for individuals to collaborate in the creation of independently organized...
Even though cloudburst events in high mountain areas can be highly destructive and result in significant losses of life, little is known definitively about these flood events. An exact
understanding of the driving processes, typical precipitation rates, and impacts of cloudburst events remain uncertain. This study seeks to advance knowledge...
This thesis describes an investigation of the molecular basis of the substrate specificity and catalytic mechanism of a unique pseudoglycosyltransferase (PsGT) enzyme, VldE. PsGTs are a newly discovered group of glycosyltransferase (GT)-like proteins that catalyze the transfer of a pseudosugar to an acceptor molecule via a C-N bond formation. This...
Human use of fossil fuels has caused a dramatic shift in the earth’s environment, with global temperatures rising and ecosystem health declining. The need for the human species to reduce our reliance on fossil fuels is apparent. This will be achieved by replacing conventional energy resources with sustainable alternatives, and...
This project examines the computational fluid dynamics (CFD) model used by Global Formula Racing (GFR) to simulate external aerodynamics for a Formula SAE racecar. It seeks to improve the accuracy of the existing model by changing mesh and physics model parameters. Accuracy of the model is quantified through comparison to...
For adult learners to succeed in their educational endeavors, adult educators and event planners must meet their needs and goals (Storksdieck, Ellenbogen, & Heimlich, 2005). The learning environment affects how adults learn and what outcomes they achieve (e.g., Hamilton & Tee, 2010; Knowles, 1990; Lim, Morris, & Kupritz, 2007; Young,...
