Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...
The YA4-H! program engages youth from across the state of Oregon in Youth Participatory Action Research in their own communities surrounding topics that they feel are important to them.

Pediococcus cerevisiae, Lactobacillus casei, Lactobacillus plantarum,
Leuconostoc mesenteroides, Lactococcus diacetylactis Bifidobacterium
bifidum, Leuconostoc oenos, and mixed cultures of Propionibacterium
shermanii and P. cerevisiae were used to ferment cucumber juice brine
(CJB) at 22-26°C for 1.5 months. Sugar utilization ranged from 14.6 to 86.1%.
pH of the fermented CJB ranged from...
Pectinmethylesterase (PME) activity in fresh cucumber
fruit was determined. The effects of several cationic
species, temperature, pH, and acetic acid on the activity
of cucumber PME was investigated. The efficacy of
blanching, infiltration with CaCl₂ or acetic acid, and
fermentation with 0 and 40 mM CaCl₂ on inhibition of
cucumber...
Stormwater runoff is a significant cause for impairment of many water bodies, a problem that will inevitably escalate due to increasing land-cover change associated with urbanization. The effect of stormwater runoff has spurred legislation and the subsequent development and adoption of Best Management Practices (BMPs) to treat stormwater. This work...
A year-long bench-scale treatability study was performed to assess the feasibility of using an activated sludge sequencing batch reactor (SBR) to treat a mixture of domestic wastewater and landfill leachate. A 50/50 (v/v) of domestic wastewater and landfill leachate was treated in a 1 L SBR operated on a 12...
