Quad SPST CMOS Analog Switches offer 1.5 ohm low on-resistance.
2013-10-31 13:30:51| Industrial Newsroom - All News for Today
Vishay Siliconix DG1411, DG1412, and DG1413 are ±15 V precision monolithic quad SPST CMOS analog switches. With 100 nsec switching times, these bidirectional products feature 4 independently selectable SPST switches. Respective configurations for DG1411 and DG1412 are NC and NO, while DG1413 has 2 NO and 2 NC switches with break-before-make operation. Max on-resistance flatness is 0.48 Ω, CS(OFF) is 11 pF, CD(ON) is 87 pF, and charge injection ranges from -60 to +135 pC over signal range.

U.K. Fracking Review Sees Low Risk to Health From Shale Drilling
2013-10-31 09:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: Risks to the public from shale-gas drilling are expected to be low as long as operations are well-regulated, a U.K. government-backed body said in a draft report. Public Health England anticipates a low risk to public health from direct releases of chemicals and radioactive material if shale gas extraction is properly operated and regulated, it said, seeking comments for the final report. Prime Minister David Camerons government has proposed the worlds most generous tax system to encourage...
Shale gas fracking a low risk to public health, review finds
2013-10-31 08:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The risks to public health from emissions caused by fracking for shale oil and gas are low as long as operations are properly run and regulated, the British government's health agency said on Thursday. Public Health England (PHE) said in a review that any health impacts were likely to be minimal from hydraulic fracturing, or fracking, which involves the pumping of water and chemicals into dense shale formations deep underground. Environmental campaigners have staged large anti-fracking protests...

Low on Natural Gas, More Cities in China Will Face Choking Air Pollution
2013-10-30 17:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: In a push to curb air pollution, China has been urging its cities to rely more heavily on natural gas and less on coal. But a shortage of natural gas is threatening that goal, as urban populations boom and domestic gas production lags, Reuters reports. Chinese officials have said that to reduce air pollution the most densely populated parts of Beijing should use only gas heat, which limits the supply of natural gas for smaller cities and forces those cities to rely on coal. Pollution levels in Chinese...
