Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

Individual Differences in Intuitive Risk Judgments

Creator:: Brunot, Alexander N.
Abstract:: The present research sought to investigate individual differences in the way individuals process intuitive risk judgments. The present investigation is centered on Fuzzy Trace Theory (Brainerd & Reyna, 1991), a developmental dual process theory of cognition which posits two ways in which individuals process information, gist and verbatim processing. 228...

Case Study: Pisgah Nantahala National Forest Plan Revision and American Ginseng Management

Creator:: Swartz, Shawn C.
Abstract:: The Pisgah and Nantahala National Forests (PNNF) are located in the Southern Appalachian Mountains. A center of biological diversity, they are also within a few hours’ drive of much of the population of the United States. Therefore, there are many desires and objectives the public has for how these national...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...

Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

Creator:: Riddell, Audrey P.
Abstract:: Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

The design of a single chip logic state analyzer

Creator:: Hung, Shih-chuan
Abstract:: This thesis describes the design of a single-chip logic analyzer. The utility of such a chip in measuring and recording digital system parameters is illustrated. Possibilities for future applications of this chip in performance monitoring of computer systems are discussed.

Improved stability in ACTFEL devices

Creator:: Khormaei, Iranpour
Abstract:: The stability of ZnS:Mn AC thin film Electroluminescence (ACEFEL) devices as demonstrated by the brightness-voltage (BV) characteristics is discussed. Two procedures for improvement of the stability are demonstrated. The first method is the addition of a CaS buffer layer to one or both interfaces of the ZnS active phosphor layer....

Low power high resolution data converter in digital CMOS technology

Creator:: Zheng, Zhiliang
Abstract:: The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...

Assessing Lateralization Models in Emotion Perception: The Impact of Emotion, Perceptual Process, and Experimental Paradigm on Visual Field Bias

Creator:: Robles, Rafael
Abstract:: There are currently three main models used to describe the pattern of hemispheric specialization (i.e., lateralization) for emotion perception: the right hemisphere hypothesis, the valence model, and the motivational model. Although evidence exists in support of all three, the variation between each pattern of results may be due to differences...

Biochemical conversion of lignocellulosic biomass to ethanol : experimental, enzymatic hydrolysis modeling, techno-economic and life cycle assessment studies

Creator:: Kumar, Deepak
Abstract:: Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation...
