SHENZHEN -- Construction began Saturday on an experimental facility which will offer a platform for Chinese and foreign scientists to work together for discovering a new kind of neutrino oscillation in Shenzhen, South China's Guangdong Province.It was the second biggest cooperation program Chinese high energy scientists ever conducted with other foreign counterparts since October 1988 when the positive-negative electron collider was built in Beijing.Through the collider, scientists from China and the United States have cooperated and carried out legions of scientific research.Saturday's construction commencement function was attended by more than 100 people, including government officials and foreign diplomats, such as Dr. Robin Staffin, Associate Director of Science in the US Department of Energy.Neutrino Oscillation is an intriguing behavior of a sub-atomic particle called neutrino.And the new facility is being built in the mountain near Daya Nuclear Power Plant, which has four reactors with a combined thermal output of 11.6 million kw in operation, and Ling'ao nuclear power plant is not far away. Both nuke power plants will serve as sources of anti-neutrinos for the experiments when the facility is finished.Workers will build three underground experimental halls which will be connected by long tunnels in the mountain that shields the experiment from unwanted cosmic radiation.Each hall will feature a 10-m deep water-pool within which eight anti-neutrino detectors will be deployed. The water protects the detectors from nearby radiation that interferes with the measurement, and helps identify surviving cosmic radiation.And the first experimental hall is expected to be ready by the end of 2008. Commissioning of the detectors in this hall will take place in 2009.Civil engineering construction is anticipated to last about two years, with installation of the last detector scheduled for 2010.Upon completion of the new facility, more than 190 scientists from six countries and regions including the Chinese mainland, Hong Kong, Taiwan Province, the United States and Russia will come over to do research work, according to Chen Hesheng, Chief of the Institute of High Energy Physics with the Chinese Academy of Sciences (CAS).The facility will have a budget of 250 million yuan (US.25 million). And China will be responsible for infrastructure construction and making of four detectors. And the United States will be responsible for making of the rest of the detectors.Wang Yifang, chief scientist on the experiment, said he was confident that the program would make an important contribution to finding a new breakthrough in China's research efforts in particle physics, starting a new horizon in world's neutrino research, and to improving the overall strength of China in science and technology.

China's production of natural gas rose 23.1 percent last year, faster than in 2006, to 69.31 billion cubic meters as the country used more "clean" energy, an industry association said.In 2006, output jumped 19.2 percent to 58.55 billion cubic meters, the China Petroleum and Chemical Industry Association (CPCIA) said. It also said that output would likely hit 76 billion cubic meters this year. China used 55.6 billion cubic meters of gas in 2006, an increase of 21.6 percent from a year earlier, according to statistics from BP.China has set a target of raising the proportion of natural gas in its total energy consumption to 5.3 percent in 2010 from 2.8 percent in 2005, amid efforts to curb pollution. Coal now accounts for about 70 percent of total energy consumption.The expansion of the natural gas infrastructure, including pipelines, reflected the rapid increases in output and consumption, the CPCIA said.China plans to start building a second east-west gas pipeline this year. The first such pipeline went into commercial operation in 2004.The new pipeline is scheduled to become operational in 2010 and will have a designed annual transport capacity of 30 billion cubic meters. It will mainly move natural gas from Central Asia to the Yangtze and Pearl River Deltas, the country's two most developed regions.Construction on another pipeline, which will link the Puguang Gas Field in the southwestern province of Sichuan, one of the country's largest, with the Yangtze River Delta, started last August.

Policemen guard the sea wall at the Yuhuankanmen Port in Yuhuan, east China's Zhejiang Province, August 18, 2007.The Southeast China provinces are girding for the imminent Typhoon Sepat with cancellation of flights, evacuations of ships, boats and more than half a million people.[Xinhua] FUZHOU -- Typhoon Sepat packing winds of 119 km per hour landed in east China's Fujian Province at 2:00 am Sunday, said the Fujian provincial meteorological station. Before the landfall in Chongwu town, Hui'an county of Fujian, Sepat landed in Hualien, the central-eastern part of Taiwan around 5:40 am Saturday, with sustained winds of 180 kilometers per hour.Power cut for thousands of households and downpours were reported in many parts of the island.Sepat also brought downpours to Hui'an with 50-80 mm of precipitation in hours, according to the local meteorological station.Some buildings in Hui'an were damaged, roofs lifted while billboards and trees were toppled down, an official with the Hui'an office of flood control.The official said the typhoon was expected to cause more damages in the county.It rained heavily in the Fujian cities of Ningde, Fuzhou, Zhangzhou and Quanzhou early Sunday morning, according to the Fujian provincial meteorological station.Sepat was moving northwest and was expected to arrive in Jiangxi Province on Sunday afternoon, said an expert with the Fujian meteorological station.More than 900,000 people in the southern Guangdong Province and the eastern provinces of Fujian and Zhejiang have been relocated to safety before the arrival of Sepat.A car wades ahead in the flood water as typhoon Sepat lands with heavy winds and downpours in Cangnan county of the coastal city of Wenzhou, east China's Zhejiang Province on August 18, 2007. [Xinhua] The provincial meteorological station has issued the highest-level warnings for Sepat.More than 540,000 people in Fujian have been relocated to safe places by 7:00 pm Saturday, according to government officials.All entries of expressways in Fuzhou, capital of Fujian, were closed, while 109 domestic and international flights at the Fuzhou airport were cancelled on Saturday. Xiamen and Jinjiang cities also cancelled outbound flights.The Ministry of Civil Affairs have sent 3,000 tents to evacuated people in Fujian.Downpours have been forecast to hit the coastal areas of Fujian and neighboring Zhejiang Province starting from Saturday night.Passenger liners shuttling from Fujian to Taiwan have been suspended since Friday afternoon and it is undecided when services will resume.In Zhejiang Province, nearly 300,000 people had been evacuated to safety and 27,704 vessels back to harbor by 6:00 pm Saturday.Rain with precipitations of up to 87 millimeters hit Wenzhou, Pingyang, Taishun between Friday afternoon and Saturday.Three large reservoirs in Wenzhou discharged 17.5 million cubic meters of water in advance to leave room for more rainwater.In Guangdong, around 70,000 fishing farm workers on the sea, fishermen and residents in low-lying areas have been evacuated to safe areas.

BEIJING - More than 50 people in the Chinese capital have been fined for spitting during the week-long May Day holidays, according to officials in charge of the city's image. Beijing's management department and civilization promotion office have jointly sent five inspection teams to patrol the downtown Wangfujing pedestrian street, Tian'anmen Square, commercial centers and railway stations to stop people from spitting, littering, random posting of advertisements and scrawling. By Sunday, 56 people were fined for spitting and refusing to correct the bad habit, according to the teams. The officials also handed out more than 10,000 bags to tourists, reminding them not to litter. The government is now anxious to correct the embarrassing habits of Chinese travelers ahead of next year's Olympics Games. And there is no better opportunity of doing it than the May Day travel spree, when an estimated 150 million Chinese will be on the road. The China National Tourism Administration has issued a circular, making travel agencies and tour guides responsible for correcting tourists' bad behavior during the holidays. Jumping the line, spitting, littering and clearing one's throat loudly in public are some of the frequently observed practices among Chinese travelers, according to a guideline prepared and released last year by the Spiritual Civilization Steering Committee (SCSC) of the Chinese Communist Party, the official etiquette watchdog. "We are supposed to remind people constantly throughout the tour, and also lead an etiquette discussion at the end of the tour," said Huang Xiaohui, a travel guide with a Beijing-based travel agency. "The Olympics are coming, and we don't want to get disgraced," Huang said, summing up the purpose succinctly.

WASHINGTON: A team of researchers found there is not much difference between the sexes when it comes to talking, when you actually count the words. The researchers placed microphones on 396 college students in the United States and Mexico for periods ranging from two to 10 days, sampled their conversations and calculated how many words they used in the course of a day. The score: Women, 16,215; Men, 15,669. The difference: 546 words: "Not statistically significant," say the researchers in Friday's edition of the journal Science. "What's a 500-word difference, compared with the 45,000-word difference between the most and the least talkative persons" in the study, Matthias R. Mehl, an assistant psychology professor at the University of Arizona, who led the research, said. He said the least talkative person in the study - a male - used just over 500 words a day, while another male topped that by more than 45,000. Co-author James W. Pennebaker, chairman of the psychology department at the University of Texas, said the researchers collected the recordings as part of a larger project to understand how people are affected when they talk about emotional experiences. They were surprised when a magazine article asserted that women use an average of 20,000 words per day compared with 7,000 for men. If there had been that big a difference, he thought, they should have noticed it. "Although many people believe the stereotypes of females as talkative and males as reticent, there is no large-scale study that systematically has recorded the natural conversations of large groups of people for extended periods of time," Pennebaker said. Indeed, Mehl said, one study they found, done in workplaces, showed men talking more. Still, the idea that women use nearly three times as many words a day as men has taken on the status of an "urban legend", he said. Agencies
