Response surface methodology (RSM) was employed to optimize the extraction of dihydromyricetin from Ampelopsis grossedentata leaves using dynamic microwave assisted multi-stage countercurrent extraction.
Under postulated accident conditions such as loss-of-coolant accidents (LOCAs) in pressurized water reactors (PWRs), steam and condensate water form countercurrent flows in a hot leg (consisting of a horizontal pipe, a 50-deg vertical elbow, and a short inclined pipe) and a pressurizer surge line (consisting of a slightly inclined pipe with elbows, a vertical elbow, and a vertical pipe), and flooding may occur.

Researches have shown that cetaceans in running-water environments prefer countercurrent pools, where they find refuge from downstream currents and where much of the biological productivity is concentrated (Smith and Reeves, 2012).
These representations stressed beauty but also authority and intellect thanks to, as the authors propose, "a previously unrecognized countercurrent of philogyny in the otherwise misogynistic Renaissance" (p.

Thus the current diverges near the US/Mexico border, splitting into the Southern California Countercurrent (strengthened by the underlying Rodriguez current) that flows east and then north to border the mainland coastline and run the length of the Southern California Bight, and a southerly branch, that parallels the Baja coastline.
