Forests dominate carbon (C) exchanges between the terrestrial biosphere and the atmosphere on land. In the long term, the net carbon flux between forests and the atmosphere has been significantly impacted by changes in forest cover area and structure due to ecological disturbances and management activities. Current empirical approaches for...
Proceedings of the 73rd Annual Western Orchard Pest and Disease Management Conference, held January 6-8, 1999 at the Imperial Hotel in Portland, Oregon.
Proceedings of the 75th Annual Western Orchard Pest and Disease Management Conference, held January 10-12, 2001 at the Imperial Hotel in Portland, Oregon.
The interface electrochemical and chemical mechanism of the low alloy steel in a 3.5% NaCl solution containing the Ce3+-based inhibitor was investigated by the electrochemical techniques in conjunction with the surface analysis technologies. It was shown that the Ce(3+-)based inhibitor was an anodic inhibitor with more than 90.0% inhibitory efficiency....
The rapid growth of aquaculture and concomitant growth in the use of compound aquafeeds have resulted in aquaculture using 35% of global fishmeal and 54% of global fish oil in 2000, up from just 10% and 16% respectively in 1988. Meanwhile, landings of reduction fish have hovered near 30 mmt,...

Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of...
