Mobile food canteens have become popular in the Baton Rouge area but are causing problems in China. Smoke from the barbecue stands are a common source of unhealthy airborne particulate matter known as PM2.5. Beijing's Bureau of City Administration and Law Enforcement insist the "stands" not only create serious air pollution but enhance noise pollution for neighborhoods. Unlicensed grill operators can be fined up to 5,000 yuan or about $815 for violating the ordinance including the confiscation of their grilling equipment for discharging smoke and noise. China's microblogging service, Sina Weibo, believes the crackdown was the government's attempt to harass and limit vendors. The most smoke is caused by specific trucks that serve mutton skewers. On the second day of Fall here in Baton Rouge, there is nothing tastier than a hot mutton skewer. In conclusion, In 1901, sponge divers discovered a mechanical device, split into 82 fragments that included bronze gears and teeth, encrusted dials and deteriorated inscriptions.  Science News reported that researchers used 3-D - X-Ray imaging to verify that the gadget was used 2100 years ago to perform complex astronomical calculations to predict solar and lunar eclipses and planetary movements. It’s known as the Antikythera mechanism, for the small Greek Island where it was discovered. Further investigation of the gadget has determined that it also chartered the four-year cycle of the Olympics and the cycles of the Greek games. A deciphered word Nemea, on the mechanism, represents the Olympiad’s Nemean games. The mechanism is 1,000 years more advanced than other devices.
