Purdue Study Aims To Boost MRI Capabilities
...an induce electric currents in the patient, called eddy currents, which then may stimulate nerves and muscles." Little human data are available on the stimulating effects of MRI gradient fields, Bourland says. "Our research is aimed at determining at what levels patients can feel the magnetic fields, and ...Giant jellies invade Gulf of Mexico threatening shrimp fishery
...lates through the Gulf, broke off the Loop into an eddy south of Alabama and the Florida panhandle. Satellite imagery from the Naval Research Laboratory at the Stennis Space Center confirms this. At the present time the jellies seem to have taken up residence and spread out across the Mississippi Sound...New method for studying ocean currents to help fight erosion
... create complex swirls and eddy currents that defy methods for stalling erosion. For instance, residents along the coastal U.S. have tried to counter erosion by adding sand to beaches or building ...NASA satellite spots unique ocean eddy

Like hurricanes, each eddy is given a name to keep better track of it. In 1999, researchers named the eddy Loretta. Around the ...Forest management may mitigate global warming
...bon dioxide levels. A tower-based method, known as eddy covariance, measured the net storage and net release of carbon into the air. Ground-based biometry, a longer-standing method, measured changes in the trees' diameter, a direct indication of carbon storage. Both measurements produced similar results -...UCSD gene therapy to prevent restenosis following balloon angioplasty receives US patent
...l causes a disturbance of blood flow pattern, with eddy motions and local flow reversal, which in turn activates a series of molecules that allow mononuclear white blood cells to enter the artery wall. At the same time, the disturbed flow speeds up the life cycle of endothelial cells. As they grow, divide...Homeland security highlights from Pacific Northwest National Laboratory
...ing the need for costly off-site analysis. Using eddy current technology, the Dual-Use Analyzer determines the electrical conductivity of the metal, then compares this signal "signature" against a built-in library of nuclear dual-use and high-value metal signatures. The system also identifies varying m...AAAS at the BA: Whale food, winners and losers in Antarctica and solar insights
