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...

Erotic Capital and Women’s Online Sexual Marketing

Creator:: Perkins, Abby M.
Abstract:: The purpose of this paper was to discuss the theory of erotic capital proposed by Catherine Hakim and how this theory affects online advertising done by sex workers. Through analyzing 29 different pages relating to the commercial sex industry, I observed how sexual capital is utilized in marketing strategies and...

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)...

Implementing a Multi-Agent Approach to a Graph-Based Topology Optimization

Creator:: Bai, Gaofeng
Abstract:: In order to solve some classic problems in traditional topology optimization, such as unknown material distribution, checker-boarding and curse of dimensionality, this thesis introduces a new method to construct a mechanical structure that can reduce mass and increase stiffness. It uses a graph to represent the skeleton of a structure....

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...

Trace analysis of surfactants in Corexit oil dispersant formulations and seawater

Creator:: Place, Benjamin J., Perkins, Matt J., Sinclair, Ewan, Barsamian, Adam L., Blakemore, Paul R., and Field, Jennifer A.
Abstract:: After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants,...

A parallel implementation of the multiple polynomial quadratic sieve

Creator:: Perkins, Virgina E.
Abstract:: Cryptographic systems are used for secure communications in the government, in industry, and by individuals. Many cryptographic systems base their security on our inability to factor quickly. For this reason, in the last few decades several fast factoring algorithms have been developed. The Quadratic Sieve is one of the best...

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...
