The mixing of fresh and salt water that occurs at an estuary also dissipates energy, as the different salinity waters combine into a state of less-ordered, uniform salinity. The mixing generates a significant 2.2 kJ of energy per liter of fresh water that flows into the sea. http://www.physorg.com/news171102611.html Technology Wed, 02 Sep 2009 10:30:03 EST news171102611 NASA scientists Maury Estes and Mohammad Al-Hamdan have been seafaring in the Gulf of Mexico, and one of them grew a bit green around the gills. It's not surprising that a space agency scientist might have trouble getting his sea legs, but what was he doing out there in the surf to begin with? http://www.physorg.com/news170353865.html Space & Earth Mon, 24 Aug 2009 18:00:01 EST news170353865 Most patients with ascites caused by liver cirrhosis are treated with diuretics in addition to dietary sodium restriction. This creates a negative nitrogen balance and promotes mobilization of ascites. Lack of response can be secondary to noncompliance to salt restriction. The standard test to monitor compliance has been assessment of 24-h urinary sodium excretion. This can be difficult because it requires 24 h of urine collection by the patient. http://www.physorg.com/news169300618.html Medicine & Health Wed, 12 Aug 2009 13:20:08 EST news169300618 A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S. http://www.physorg.com/news168778403.html Space & Earth Thu, 06 Aug 2009 11:53:59 EST news168778403 NOAA-supported scientists, led by Nancy Rabalais, Ph.D., from the Louisiana Universities Marine Consortium (LUMCON), found the size of this year's Gulf of Mexico dead zone to be smaller than forecasted, measuring 3,000 square miles.
