Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

WHO | A study of typhoid fever in five Asian countries

IntroductionMethodsResultsDiscussionConclusionTyphoid fever is a systemic infection caused by Salmonella enterica serotype Typhi (S. typhi). The disease remains an important public health problem in developing countries. In 2000, it was estimated that over 2.16 million episodes of typhoid occurred worldwide, resulting in 216 000 deaths, and that more than 90% of this morbidity and mortality occurred in Asia.1 Although improved water quality and sanitation constitute ultimate solutions to this problem, vaccination in high-risk areas is a potential control strategy recommended by WHO for the short-to-intermediate term.2 Two safe and efficacious typhoid vaccines, the injectable Vi polysaccharide and the oral Ty21a, have been licensed; and new, improved candidate vaccines are currently being tested.3–5 However, typhoid vaccination has not been implemented as a routine public health measure in most typhoid-endemic countries despite the low price of the vaccine (Vi polysaccharide costs ca. US$ 0.50 per dose) and the high cost of trea...Get price

Carbon Tax BillSouth Africa’s GHG emissions are among the highest in the world and its absolute carbon dioxide (CO2) emissions rank among the top twenty countries, “with emissions per capita in the region of 10 metric tons per annum.”The 2011 National Climate Change White Paper described this challenge as follows: South Africa has national and international legal obligation to reduce its emissions. The Bill of Rights section of the South African Constitution includes an environment clause, which states that South Africa is party to a number of multinational environmental agreements. These include the United Nations Framework Convention on Climate Change (UNFCCC), which South Africa ratified in 1997; the Kyoto Protocol, which South Africa ratified in 2002; and the Paris Agreement on Climate Change, ratified by South Africa in 2016.In the 2009 Copenhagen Climate Change Conference, South Africa committed to reducing its GHG emissions by 34% below its current levels (see below) by 2020 and 42% below c...Get price
