The purpose of this project is to assist the OSU Baja Racing vehicle in turning more sharply. This is done using a turning brake, which locks one rear wheel to facilitate turning on a smaller radius. This project focuses on the development of a custom cylinder housing for the turning...
Rhizopogon salebrosus is an abundant ectomycorrhizal fungus common throughout Western North America that forms mutualistic partnerships with Pinus species. Studied for its systematics, use in sapling nurseries, post-fire seedling establishment, and unique evolutionary history, R. salebrosus holds many secrets within its genome. This thesis aims to characterize the mating system,...
Low-Income urban African American (LIU-AA) youth are at high risk for HIV/STIs and adolescent pregnancy. Sexual health websites (SHWs) offer an inexpensive, easy-to-disseminate, and potentially highly-accessible method of improving sexual health knowledge, awareness, and help-seeking. The present study examined engagement regarding sexual health websites for at-risk, LIU-AA youth. We conducted...
The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...
Perdeutero-spiropentane (C₅D₈) has been synthesized and infrared and Raman spectra are reported for the first time. Wavenumber assignments are made for most of the fundamental vibrational modes. Gas phase infrared spectra were recorded at a resolution (0.002 cm⁻¹) sufficient to resolve individual rovibrational lines and show evidence of strong Coriolis...
The strained carbon ring, bicyclo[1.1.1]pentane, was synthesized by a reaction between
1-(phenylsulfanyl)bicyclo[1.1.1]pentane, prepared from propellane, and Raney nickel.
Infrared spectra were recorded at a resolution of 0.0015 cm-1, a resolution significantly
better than previous measurements, 0.06 cm-1. A single fundamental band was analyzed
to determine the ground state and excited...
The action of pendant, polyethylene oxide (PEO) brush layers as nonfouling coatings for
biomedical materials is well understood. However progress toward clinical application of stable, high density PEO coatings has historically been impeded by the lack of cost effective, noninvasive methods for their preparation. Triblock polymers featuring a hydrophobic, polypropylene...

The action of pendant, polyethylene oxide (PEO) brush layers as nonfouling
Effective surface coatings for tissue-contacting medical devices should prevent both biofilm formation and infection. One method to achieve this aim is protein repellant polyethylene oxide (PEO) brush coatings loaded with antimicrobials. Previous research has demonstrated that the antimicrobial nisin adsorbs to PEO brush layers in multi-layer amounts and suggests that...
Amyotrophic Lateral Sclerosis (ALS) is a relatively rare neurodegenerative disorder that is fatal 2-4 years after the onset of the disease. Population studies are being done in order to help reveal candidates for further studies of disease etiology, disease progression, as well as to further understand racial and ethnic variations....
