As computational power increases, so does the desire to use computational simulations while designing fuel plates. The downside is multi-physics simulations – or more specifically, fluid–structure interactions (FSI) as addressed herein – require a larger amount of computational resources. Current simulations of a single plate can take weeks on a...
The system of partial differential equations which governs the
motion of a Newtonian fluid has been known for over a century. Yet,
due to the complexity of the equations, an analytical solution is known
only for a few simple geometries or a few special cases such as very
slow motion....
Emergy (spelled with an "m") and its economic equivalent emdollars evaluate the work done by the environment and by the human economy on a common basis. Making choices that maximize emdollar contributions of environment and economy is a useful public policy.. Emergy-emdollar evaluation of salmon pen culture is presented in...
Plantation forests on mountainous areas in Tanzania, East Africa, were successfully
established in the 1950's. Harvesting started in the 1970's to meet increased national
timber demand. Current problems of unharvested areas and potential environmental
degradation are associated with uncontrolled harvests, mismatch of harvest systems to
site needs, and post-harvest practices....

This report presents a summary of the principal geologic and physiographic features of the upper part of the Snake River Canyon between Oregon and Idaho. The area discussed extends from Farewell Bend near Huntington, Oregon downriver to Granite Creek 6 miles below Hells Canyon Dam, a distance of 94 miles....
Lagrangian particle tracking (LPT) models are used to explore how physical processes influence the transport of particles (e.g., eggs, larvae, or propagules) in the ocean. On the Oregon continental shelf and slope, the Northern California Current System (CCS) is influenced by spatially and temporally variable coastal currents driven by weather,...
