Assessing Chemical Dispersants Used During the Deepwater Horizon Oil Spill : Method Innovation and Application

Creator:: Perkins, Matt J.
Abstract:: Large quantities of the chemical oil dispersant Corexit were applied in the Gulf of Mexico (Gulf) in response to the Deepwater Horizon oil spill. Large data gaps regarding the potential transport, persistence and impact of Corexit in the Gulf existed at the time of the emergency response. Analytical methods for...

Land cover at northern spotted owl nest and non-nest sites, east-central Coast Ranges, Oregon

Creator:: Perkins, John P.
Abstract:: This study examined the differences, at various scales, between northern spotted owl (Strix occidentalis caurina) nest sites and non-nest sites, i.e., sites where no nests were found during surveys, in the Coast Ranges of Oregon. I compared land cover around 41 owl nest sites (ONS) and 41 non-nest sites (NNS)...

Interlayer Electronic Interactions in Twisted and Stacked Bilayer Graphene

Creator:: Patel, Hiral
Abstract:: The photophysical properties of two-dimensional (2D) layered van der Waals (vdW) materials, and their heterostructures are manifestly distinct from crystalline bulk materials. Recently, the discovery of new 2D vdW materials and strongly-bound interlayer excitons in these materials has created a new branch in nanoscience. As such, there are a number...

Toward making the invisible visible : studying science teaching self-efficacy beliefs

Creator:: Perkins, Catherine J.
Abstract:: This dissertation consists of two articles to be submitted for publication. The first, a literature review, makes visible common influences on science teaching self-efficacy beliefs and also points to potentially invisible validation concerns regarding the instrument used. The second investigates the participants' invisible science teaching self-efficacy beliefs and, through the...

Novel characteristics (Intra and Ex planta) of indigenous serogroups of rhizobium meliloti

Creator:: Busse, Matt D.
Abstract:: This thesis presents novel findings regarding symbiotic, physiological, and antigenic characteristics of representatives from an indigenous soil-borne population of Rhizobium meliloti. Nodules were sampled from 'Vernal', 'Anchor', and 'Saranac' alfalfa, and the isolates analyzed serologically. Rhizobium meliloti serogroup 31 was identified as a dominant nodule occupant, with a greater and...

The design of an aquatic insect imaging device as part of a system to automate insect classification for biomonitoring

Creator:: Sarpola, Matt J.
Abstract:: Population counts of aquatic insects are a valuable tool for monitoring the water quality of rivers and streams. However, the handling of samples in the lab for species identification is time consuming. An aquatic insect imaging device was designed as part of a system to automate aquatic insect classification and...

Employee theft : a study of the major sociological, economic and business causal theories

Creator:: Voit, Irene Elaine
Abstract:: Although employee theft is claimed by many authors to be a significant problem in America with corrosive and damaging effects upon business and society, very little research has been done to establish the causes of such behavior. The purpose of this thesis was to identify, discuss, and critically evaluate theories...

Expanding the scope of a Diels-Alder approach to biaryl synthesis

Creator:: Schwartz, Johanna Perkins
Abstract:: A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...

Model systems for structural investigations into peroxiredoxin catalysis, conformation change, and inactivation

Creator:: Perkins, Arden
Abstract:: Peroxiredoxin (Prx) enzymes catalyze the reduction of hydrogen peroxide, peroxynitrous acid, and organic peroxides, and are extremely efficient peroxidases, with k[subscript cat]/K[subscript M] on the order of 10⁷ - 10⁸ M⁻¹ s⁻¹. Besides their role in oxidative stress defense, evidence has accumulated that some eukaryotes, including humans, use Prxs as...
