Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

Estimation of leaf area index and simulation of evapotranspiration for intensively managed Douglas-fir forests

Creator:: Rogers, Nicole S.
Abstract:: Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...

Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

Creator:: Tai, Leah Chung-Mei
Abstract:: Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...

Modeling Student Engagement in Online Learning Environments Using Real-Time Biometric Measures : Electroencephalography (EEG) and Eye-Tracking

Creator:: Elatlassi, Rime
Abstract:: Online learning, also known as e-learning, has become an increasingly popular and important component of higher education. Current literature indicates that higher education institutions rely on online learning to meet instructional loads and mitigate increasingly complex course scheduling problems. Students also find it more convenient to finish their college curricula...

Runoff and Sediment Transport from Harvested Hillslopes to Riparian Buffers of Rocky Mountain Headwater Catchment

Creator:: Puntenney-Desmond, Kira C.
Abstract:: Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...

Classification of Native Vegetation of Oregon - 2019

Creator:: Kagan, James S., Brunner, Rachel L., and Christy, John A.
Abstract:: This classification is an update of the 2004 classification of native vegetation of Oregon by Kagan, Christy, Murray and Titus. As before, this classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were part of the presettlement landscape of...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

"Instead of tumbleweed, we have mitigation systems" : an ethnography of toxics risk, mitigation, and advocacy in IBM's deindustrialized birthplace

Creator:: Little, Peter C.
Abstract:: This dissertation draws on ethnographic data and political ecological theory to analyze the experience of residents living in the IBM-Endicott Superfund site in Endicott, New York. Combining in-depth narratives and quantitative measures from a household survey, it highlights residents' perceptions of 1) environmental health risk, 2) risk mitigation, 3) deindustrialization...
