Environmental contaminants and breeding biology of great blue herons in the Columbia River Basin

Creator:: Thomas, Carmen M.
Abstract:: Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....

Analytical approach to the quantitative analysis of silicon in plants : its application to plant silica extraction

Creator:: Boone, Carmen E.
Abstract:: The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...

Microwave extraction of peppermint oil and comparison to the currentpractice of steam extraction

Creator:: Velasco, Carmen A.
Abstract:: The increase of diesel fuels and natural gas has increased the energy cost of the mint oil extraction industry in the Willamette Valley. In this study the energy evaluation of a distillation facility in Oregon is considered. Solvent free microwave extraction of peppermint oil is introduced as a new technique...

Does self-transcendence explain baby boomers' volunteer hours?

Creator:: Cox, Michelle J.
Abstract:: The goal of this study was to pursue the construct of transcendence from a psychosocial, developmental perspective to predict who will volunteer and its influence on the average number of volunteer hours worked per week. The predictor variable is the self-transcendence subscale score on the Adult Self-Transcendence Inventory (ASTI) (Levenson...

Systems evaluation of the Guatemalan eye care project – Enfoque Ixcan : barriers and avenues for providing eye care services to rural Guatemala

Creator:: Terhes, Amanda Foshay
Abstract:: This thesis evaluates the programs, activities, and relationships of Enfoque Ixcan, a non-profit eye care project providing services to a rural area of Guatemala. I conducted ethnographic interviews with key stakeholders of the organization and carried out participant observation in the Ixcan region of Guatemala in February 2006. The research...

Effect of pharmaceuticals and natural products on multidrug resistance mediatedtransport in Caco-2 and MDCKII-MDR1 drug transport models

Creator:: Fan, Ying
Abstract:: This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

Effective decision-theoretic assistance through relational hierarchical models

Creator:: Natarajan, Sriraam
Abstract:: Building intelligent computer assistants has been a long-cherished goal of AI. Many intelligent assistant systems were built and fine-tuned to specific application domains. In this work, we develop a general model of assistance that combines three powerful ideas: decision theory, hierarchical task models and probabilistic relational languages. We use the...

Accuracy versus cost in distributed data mining

Creator:: Deutschman, Stephanie
Abstract:: A basic tradeoff to consider when designing a distributed data-mining framework is the need for a compromise between the cost of communication and computation resources and the accuracy of the mining results. This is essentially a decision of whether it is more efficient to communicate all of the data to...

A SAT-based planning framework for optimizing resource production

Creator:: Ventura, Christopher
Abstract:: Domain-independent automated planning is concerned with computing a sequence of actions that can transform an initial state into a desired goal state. Resource production domains form an interesting class of such problems, in that they typically require reasoning about concurrent durative-actions with continuous effects while minimizing some cost function. Although...

Evolving character controllers for collision preparation

Creator:: Rose, Robert W.
Abstract:: Full dynamic control of physically simulated characters is the holy grail of video games and other interactive applications. Recent advances in the field have presented controllers that can handle the balance and fall response after a collision. This thesis addresses the development of a controller that handles the response before...
