Undergraduate students are expected to find, evaluate and use peer-reviewed or scholarly literature, but they rarely learn about the process of creating new knowledge or the roles the literature plays in the work of scholars. A desired outcome of undergraduate education is the understanding that knowledge is created, evolving and...
Wave Energy AS (WE) is an ocean energy company from Norway established to develop, test, market and commercialize the patented SSG™ wave energy converter technology.

Heat activated cooling has the potential of utilizing thermal sources that currently go unused such as engine exhaust heat or industrial waste heat. Using these heat sources can provide enhanced energy utilization and reduced fuel usage in applications where cooling is needed. The concept developed here uses waste heat from...
The effect of copper naphthenate treatment on electrical resistance of Douglas-fir utility poles was compared with similar
poles either left untreated or treated with pentachlorophenol (penta). Penta-treated and untreated wood had similar electrical
resistance shortly after treatment and after a 3-month outdoor weathering period. Electrical resistance of copper naphthenate–
treated...
Numerous studies have demonstrated statistical associations between the El Niño–Southern Oscillation (ENSO) and precipitation in the Mediterranean basin. The dynamical bases for these teleconnections have yet to be fully identified. Here, observational analyses and model simulations are used to show how ENSO variability affects rainfall over southwestern Europe (Iberia, Southern...
