Reliable estimates of plant biomass and leaf surface area are essential for studying primary production, nutrient cycling, hydrology, wildlife management, and fire. This paper presents equations that can be used to make such estimates for most plant species-trees, shrubs, and herbs-dominant in western and central Oregon.' We also document the...
There is increasing evidence that our planet is warming and this warming is also resulting in rising sea levels. Estuaries which are located at the interface between land and ocean are impacted by these changes. We used CE-QUAL-W2 water quality model to predict changes in water temperature as a function...
Muddy and/or musty off-flavors in farmed-raised catfish occur as a result of the absorption of geosmin (GEO) and 2-methylisoborneol (MIB), compounds produced by algae. Previous research suggests the acid pH-shift method may be able to reduce off-flavors to produce a consumer acceptable product. The objective of this research was to...
Atomically-thin graphene sheets have unprecedented characteristics for biosensing applications. These characteristics include mechanical flexibility and strength, optical transparency, electrical sensitivity and biocompatibility. The primary theme of this dissertation is the characterization and application of graphene field-effect transistors (FETs) in biologically-relevant physiological environments.Understanding the interface that forms between an electrolyte and...
This thesis complicates the traditional associations between authorship and alphabetic composition within the comics medium and examines how the contributions of line artists and writers differ and may alter an audience's perceptions of the medium. As a fundamentally multimodal and collaborative work, the popular superhero comic muddies authorial claims and...
This thesis examines perceptions of cooperation among small to medium sized enterprises (SME) in western Oregon's forest products industry. Recent changes in the industry, such as corporate consolidation, global marketing, and government regulations have created an environment in which many SMEs find it difficult to stay competitive. Cooperation among SMEs...
Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...
This research focused on the accuracy of trait judgments at zero acquaintance and after five minutes of interaction. Thirty-five undergraduates judged the neuroticism, extraversion, openness, agreeableness, and conscientiousness of four to six others whom they did not know. Participants then interacted in one-on-one conversations with each target for five minutes....
