Potent GHG insulating gas rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price

Health care quality in Africa: Uganda, Nigeria, Tanzania

NigeriaSouth AfricaKenyaZimbabweZambiaTanzaniaUgandaOther African NationsIf You’Re Moving OverseasWhile Nigeria has a public health service financed through a national insurance scheme, newcomers to the country might want to consider their own private medical insurance, use private health care facilities, and make sure they are covered for repatriation (in the event of death) or medical evacuation to another better-equipped country, if necessary. Public health care is improving, but it faces a number of difficulties including a low ratio of doctors at only 1 per 2,000 inhabitants(low on a global scale but higher than most of its African neighbours) and an infrastructure struggling to cope. The country spends 3.7% of its GDP on health care: a figure well below global average but on par with many of the countries around it. Although it has a network of multi-discipline hospitals, mainly in the more urban areas, doctors complain of low pay.
