In this dissertation, I describe spectroscopic studies of jet-cooled polycyclic aromatic hydrocarbons (PAH) and one nitrogen substituted PAH (PANH) using pulsed field zero kinetic energy (ZEKE) photoelectron spectroscopy and resonantly enhanced multiphoton ionization (REMPI) spectroscopy. Recently, there has been a demand for far-infrared (FIR) spectral information of astrophysically relevant molecules...
The soil bacterium Pseudomonas protegens Pf-5 can colonize root and seed surfaces of many plants, protecting them from infection by plant pathogenic fungi and oomycetes. The capacity to suppress disease is attributed to Pf-5's production of a large spectrum of antibiotics, which is controlled by complex regulatory circuits operating at...

We report here on recent developments and advances in pore-scale x-ray tomographic imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid flow, i.e., the displacement of one immiscible fluid by another inside a porous material, which is of central importance to many natural and engineered processes....
A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay
processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the
77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of
¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...
Across-shelf transects over the eastern flank of Barrow Canyon were obtained in August 2005 with an autonomous underwater vehicle (AUV). Here, the shelf topography creates a “choke” point in which a substantial portion of Pacific inflow from the Bering Strait is concentrated within 30 km of the coast, providing an...
Seafood inspection and certification has become a trend on international trade. Recent incidences of chemical residues were examined in exporting seafood products which hinder the future export to the European Union and Japan particularly. Hence, the perceptions of seafood quality and safety from a consumer point of view and international...
The television show South Park, created by Trey Parker and Matt Stone, is viewed by millions of people each week, regularly addresses a number of controversial issues and plays a major role in contemporary popular culture. Current academic research acknowledges Parker and Stone's willingness to attack the dominant views surrounding...
The purpose of this study was to explore motivations behind participation in cosplay and the use of social media among cosplayers who maintain Facebook Artist Pages. Further focus was placed on investigating the role of Facebook Artist Pages in building fame. To explore such motivations, two theories were referenced: Deci...
