Experimental thermodynamic first and second law analysis of a variable output 1-4.5 kWe, ICE-driven, natural-gas fueled micro-CHP generator

Creator:: Taie, Zachary and Hagen, Christopher
Abstract:: This work experimentally assesses the thermodynamic performance of the only single kWe, variable-output continuous duty, internal combustion engine driven, residential micro-combined heat and power (mCHP generator (Marathon Engine Systems ecopower) available in the United States. The system underwent steady state testing over its full operating range, and first (energy) and...

Public lands and private waters: scarce mesic resources structure land tenure and sage-grouse distributions

Creator:: Donnelly, J. P., Naugle, D. E., Hagen, C. A., and Maestas, J. D.
Abstract:: Water scarcity in semiarid environments provides a model system to evaluate the role of mesic resources in structuring the distribution and abundance of wildlife. We used remote sensing and point process analyses to evaluate spatio–temporal variability in limited mesic resources in relation to greater sage-grouse (Centrocercus urophasianus) distributions in Oregon,...

Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...

Design considerations for small scale rotating fluidized beds in static geometry with screens for fine particles

Creator:: Lavrich, Zoe, Wagner, David R., Taie, Zachary, Halliday, Devin, and Hagen, Christopher L.
Abstract:: Design of a small scale rotating fluidized bed (RFB) with diameter of 4-6 cm to fluidize 40-80 mu m diameter particles was investigated using computational fluid dynamics (CFD). Simulations explored the impact of the following components on pressure drop and fluidized behavior of the device: particle size, particle density, outer...

Assessing earth system model predictions of C-4 grass cover in North America: From the glacial era to the end of this century

Creator:: Still, Christopher J., Cotton, Jennifer M., and Griffith, Daniel M.
Abstract:: Aim C-4 grasses are distinct from C-3 grasses, because C-4 grasses respond in a different manner to light, temperature, CO2 and nitrogen and often have higher resource-use efficiencies. C-3 and C-4 grasses are typically represented in earth system models (ESMs) by different plant functional types (PFTs). The ability of ESMs...

Early adulthood: A developmental perspective on suicide prevention and intervention

Creator:: Kerr, David C. R.
Abstract:: Early adulthood is a time of transition when large segments of the population embrace new roles and show decreases in behaviors and problems thought to underlie suicide risk. Still, other segments show emergent or worsening psychopathology per-haps exacerbated by age-related disconnection from prior relational and institutional supports. Suicide prevention efforts...

Effects of fuel content and density on the smoldering characteristics of cellulose and hemicellulose

Creator:: Smucker, Benjamin D., Mulky, Tejas C., Cowan, Daniel A., Niemeyer, Kyle E., and Blunck, David L.
Abstract:: Smoldering combustion in wildland fires poses hazards for both ecosystems and humans by destroying biomass, transitioning to flaming combustion, and releasing significant quantities of pollution. Understanding the parameters that control smoldering is necessary to help predict and potentially mitigate these hazards. A challenge in identifying these parameters is the wide...

Scaling up sustainability in commodity agriculture: Transferability of governance mechanisms across the coffee and cattle sectors in Brazil

Creator:: Hajjar, R., Newton, P., Adshead, D., Bogaerts, M., Maguire-Rajpaul, V. A., Pinto, L. F. G., McDermott, C. L., Milder, J. C., Wollenberg, E., and Agrawal, A.
Abstract:: A number of governance mechanisms address socio-environmental challenges associated with commodity agriculture in tropical forested countries. Governance mechanisms that prove effective in one agricultural sector are often applied to other sectors as well. For example, voluntary certification programs have been adopted by producers of commodities as diverse as beef, coffee,...

Seasonal changes in leaf nutrient concentration of male and female hardy kiwifruit grown in Oregon

Creator:: Vance, A. J. and Strik, B. C.
Abstract:: Leaf nutrient concentration of hardy kiwifruit [Actinidia arguta var. arguta (Siebold and Zucc.) Planch. ex Miq.] was evaluated throughout two growing seasons (2008-2009) for determinate and indeterminate shoots of female ('Ananasnaya') and male vines. While research has been conducted on the more commonly grown fuzzy kiwifruit (A. chinensis var. deliciosa...

The Politics of Correctional Privatization in the United States

Creator:: Burkhardt, Brett C.
Abstract:: Research Summary: Private correctional firms are political actors. They work to create favorable conditions to market their services. At the same time, they are constrained by external political forces, including political parties, social movements, and public opinion. This article reviews what we know about the reciprocal relationship between the private...
