Abstract Gas pool coupled activating TIG (GPCA-TIG) welding put forward in-house can dramatically enhance weld penetration of TIG welding through introducing active element oxygen to reverse the Marangoni convection flow in the molten Dog Toys pool.In order to further improve the welding productivity, the normal solid tungsten electrode is replaced
The progress in gene drive research has made the possibility of a future release in the environment probable.This prospect is raising new questions related to the adequacy of the policy frameworks in place to manage and regulate the research and its outcomes responsibly.A number of international mechanisms are exploring how to evaluate this technol
Precipitation is 24" Barstool a critical variable to monitor and predict meteorological drought.The WMO recommended standardized precipitation index (SPI) is calculated from gauge (i.e.GPCC), satellite-gauge (GPCP, CHIRPS), reanalysis (i.e.ERA-Interim, and MERRA-2), and satellite-gauge-reanalysis (i.e.MSWEP) over the global domain.Measured differen
