Fuel reduction treatments are being applied to public lands, affecting significant acreage at considerable expense. This study compares the short term effects on a chaparral plant community of two different fuel reduction methods, brush mastication and "hand piling and burning" (HPB). Ceanothus cuneatus dominated the southwestern Oregon study sites where...
The intent of this report is to provide a brief description of water quality issues in Nicaragua, Uganda and Bangladesh, and the technologies available to address these issues. The water quality parameters considered include: bacterial contamination, heavy metals and arsenic, pesticides and industrious chemicals, turbidity, radiological characteristics, and taste and...
A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...
The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...
Hunter-gatherers depend on naturally occurring resources and, in order to survive, must overcome resource procurement challenges inherent in their environment. One challenge relates to the temporal and spatial availability of resources, which hunter-gatherers address, in part, through the strategic use of space to position themselves for optimal access to necessary...

A growing body of research has connected bullying victimization to a number of risk factors in adolescents, including substance use. The current study utilizes Agnew’s revised strain theory as a theoretical framework to examine this relationship, as well as patterns of substance use across gender, race, and mental health status....
Increasing access to modern forms of energy in developing countries is a
crucial component to eliminating extreme poverty around the world. Pico-hydro
schemes (less than 5-kW range) can provide environmentally sustainable electricity
and mechanical power to rural communities, generally more cost-effectively than
diesel/gasoline generators, wind turbines, or solar photovoltaic systems....
During spring and early summer hydropower projects are often forced to spill water through their spillways due to increased river flows of the runoff season. Flows which are directed through spillways--instead of through turbines--contain a substantial amount of energy. Stemming from the high energy content, spillway flows entrain air at...
Education as a right has taken off internationally with expanded national policies in recent years. Across Africa over 80% of countries have abolished tuition fees for primary education and several have made the leap to free secondary education as well. With decreased financial barriers keeping kids out of the classroom,...
