Long-haul diesel trucks carry the lion’s share of all shipped goods in the United States. The drivers of these trucks often live in these trucks for days, sometimes weeks, at a time as they deliver these goods. When stopped overnight, many of these drivers leave their engines idling to heat...
In order to reduce long-term idling along the Oregon I-5 corridor, the US Environmental Agency entered into a collaborative research and implementation program with Oregon State University, the Oregon Climate Trust, and Shurepower (producers of truckstop electrification equipment) to install Shurepower stations at truck stops in Oregon. This research component...
Prior studies have demonstrated that juvenile walleye pollock Theragra chalcogramma forage socially in schools for spatially and temporally clumped food, but forage more independently for spatially and temporally dispersed food. One advantage of social foraging is that fish in schools may be able to locate more food clumps than fish...
Walleye pollock and sablefish, as 0+ yr juveniles, are pelagic particulate feeding planktivores. We conducted a series of laboratory experiments to determine how illumination influences prey consumption in these species, utilizing live Artemia sp. as prey. Both juvenile walleye pollock and sablefish were characterized by a sigmoidal relationship between the...
Research was undertaken to examine the influence of light intensity on the shoaling behavior, activity and anti-predator behavior of juvenile walleye pollock Theragra chalcogramma. Under a 12 h light/12 h dark photoperiod, juveniles displayed a diurnal shoaling and activity pattern, characterized by fish swimming in cohesive groups during the day,...

The uptake of hydrogen by lanthanum pentanickel (LaNi₅) to form lanthanum nickel hydride (LaNi₅H₆) is
followed with three-dimensional imaging by neutron tomography. The hydrogen absorption process is
slower than the time needed for acquiring a single radiograph, about 10 s, but fast relative to the time
to acquire a fully-sampled...
Rockfish species of the genus Sebastes are notable for being numerous and diverse. Rockfishes are unusual among fish because they fertilize their eggs internally and release live, swimming larvae. They undergo complex courting behaviors, which may allow females to be selective about their mates. The major histocompatibility complex (MHC) has...
