HAIKOU, Jan. 28 (Xinhua) -- China's aviation authorities on Friday started to allow helicopters to fly in low-altitude airspace over the tourist island of Hainan on a trial basis for the first time. The aim is to eventually open a part of the country's tightly-controlled airspace to private aircraft.Four helicopters were manned by eight pilots from Shanghai-based Zhengyang Investment Group, a leading domestic firm in the general aviation industry. They are expected to conduct test flights in the sky, 1,000 meters above the ground in Hainan in the next two months.The flight test will collect data for low-altitude flying and test the ground control system's response to emergencies, said Zou Jianming, chairman of Zhengyang Investment Group.Hainan is the first place in China to conduct test flights of private aircraft in low-altitude airspace, said Jiang Sixian, deputy governor of the province. Domestic and foreign firms are both welcome to invest in Hainan's general aviation sector to develop world-class tourism here.China's low-altitude airspace is controlled by the Air Force and the Civil Aviation Administration of China (CAAC). Every private aircraft flight needs approval, and the procedure can take from one day up to a week.But last November, the State Council and the Central Military Commission said that part of the low-altitude airspace would be opened to promote the country's general aviation sector, including the purchase and use of private planes.General aviation refers to the part of the aviation industry that excludes flights for military, law enforcement and public transport. China has only 900 aircraft, 80 airports and fewer than 10,000 pilots in the general aviation segment.The market for general aviation in China is valued at only 13 billion yuan (1.98 billion U.S. dollars) but is expected to grow by 15 percent annually until 2020, Hainan aviation officials said.

BEIJING, May 14 (Xinhua) -- From 24-hour complaint hotlines to instant additive detectors, local governments in China are striving to battle the illegal use of food additives following a string of food scandals.According to a statement released Saturday by the office of the food safety commission under the State Council, China's Cabinet, governments in Beijing, Shanghai, Zhejiang and Guangdong have incorporated the local food safety situation into the evaluation of officials' work, while ordering strengthened and coordinated food safety supervision at city and county levels.Many provinces and autonomous regions are distributing educational information through local media to promote, among the local population, the awareness of food safety and the harm of banned food additives, stressing severe punishment in the hope of intimidating potential violators.Certified food additives are displayed on shelves at a store that sells food additives in Beijing, capital of China, April 22, 2011.Law enforcement departments in Chongqing, Guangdong, Liaoning and Hunan have punished violators involved in a series of food scandals which included "poisonous bean sprouts," "inked vermicelli" and "dyed peppers," according to the statement.The document did not provide details on these cases.Meanwhile, governments are figuring out new measures to stem food violations.For instance, the provincial government of northeastern Jilin has set up round-the-clock hotlines for food safety complaints and recruited 1,300 voluntary food safety supervisors who go deep into communities for clues on potential food scandals.Supervisors in southern Guangxi Zhuang Autonomous Region were equipped with additive detecting devices, which are reportedly able to check 27 kinds of illegal food additives "quickly and correctly," including melamine and clenbuterol, a kind of fat-burning drug used by violators to feed pigs to prevent them from accumulating fat.The municipal government of Beijing stipulates that companies found to have committed food violations in the past would be limited in investing in the municipality, while principals responsible for the wrongdoings will be banned from food manufacturing and distribution businesses.Beijing also requires restaurants to inform customers of all food additives contained in their self-made beverages and food sauces by posting the lists in menus or other public places. The lists should also be reported to supervisory departments.According to the statement, the Ministry of Agriculture has sent five teams to various regions, including Hebei, Jilin and Heilongjiang to inspect local food safety conditions.Vice Premier Li Keqiang warned last month of the great harm caused by illegal additives in food during a high-profile national meeting, promising a "firm attitude, iron-handed measures and more efforts" in dealing with the problem."Once such a case surfaces, it has an extensive social impact and easily causes a ripple effect, so we must attach great importance to it," Li said, adding that severe penalties must be imposed on violators to "let the violators pay dearly" and send a message to others.A high-profile, nationwide fight against the illegal use of additives in food was then launched to intensify supervision, upgrade safety standards and greatly increase penalties for violators.The moves came following a series of scandals including steamed buns dyed with unidentified chemicals, as well as the use of illegal cooking oil, known as "gutter oil."In one of the latest cases, police detained 96 people for producing, selling or using meat additives and confiscated over 400 kg of clenbuterol, widely known in the country as "lean meat powder," in central Henan Province.The action followed a scandal revealed in March when the country's largest meat processor, Shuanghui Group, was forced to issue a public apology for its clenbuterol-tainted pork products.

RIO DE JANEIRO, March 25 (Xinhua) -- The number of dengue fever cases in Rio de Janeiro city this year has already surpassed 10,000, local health authorities said on Friday.According to the city's Health Secretariat, in less than three months, the number of confirmed dengue fever cases in Rio reached 10,158, exceeding the figures registered in the entire years of 2009 (2,723) and 2010 (3,120).In Rio de Janeiro state, the number of confirmed dengue fever cases reached 20,150, and the death toll rose to 18.This week, the first two cases of type-4 dengue fever in Rio de Janeiro state were confirmed in the city of Niteroi. The type-4 dengue fever is not more dangerous than the other types, but as the disease had not been registered in the region before, the local population has no immunity to it.As there are four different types of dengue fever, a person can develop the disease several times.The last epidemic of dengue fever in Rio de Janeiro state occurred in 2008 when 174 people died of the disease and some 250,000 cases of dengue were registered.

SAN FRANCISCO, April 5 (Xinhua) -- The appeal of tablet computer and electronic-book reader (e-reader) has been giving a boost to semiconductor market as sales of chips for such devices surged in 2010 and keeps growing, market research firm International Data Corp. (IDC) said on Tuesday.A new IDC report showed that worldwide revenues for media tablet and e-reader semiconductors grew by over 2,000 percent to 3. 3 billion U.S. dollars in 2010 as semiconductor suppliers enabled original equipment manufacturers to bring new products to market less than 8 months after Apple Inc. launched its iPad tablet.According to IDC's definition, media tablets are devices with color displays larger than 5-inch and smaller than 14-inch, running lightweight operating systems and able to be based on either x86 or ARM processors."The opportunity for semiconductors in media tablets and e- readers has exploded and semiconductor suppliers are scrambling to bring to market semiconductor and software platforms to enable these products," Michael Palma, a senior research analyst at IDC, said in a statement.Looking forward, IDC said it expects media tablet and e-reader semiconductor revenues to grow by 120 percent year over year in 2011, predicting that the market will be boosted by the arrival of a new version of Google Inc.'s Android operating system, dual core processors and increased bandwidth."For the next several years, we will see rapid innovation cycles for products launched into the marketplace and semiconductor suppliers will continue to satisfy evolving end user requirements over the coming years," Palma noted.

LOS ANGELES, March 16 (Xinhua) -- The death rate in the United States reached an all-time low in 2009, dropping 2.3 percent from 2008, a newly released report said.This was the 10th straight year of decline, demonstrating that Americans are living longer than ever, according to the report from the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics.The nation saw a drop from 758.7 deaths per 100,000 people in 2008 to 741 per 100,000 people in 2009 when 2,436,682 deaths were reported, said the report published by HealthDay News on Wednesday.However, life expectancy for blacks remained unchanged -- 70.9 years for men and 77.4 years for women. The disparity between whites and blacks is now 4.3 years, representing a 0.2 percent increase from 2008 to 2009, the report found.The report said that deaths fell in 10 of the 15 leading causes of death -- heart disease dropped 3.7 percent, cancer fell 1.1 percent, and stroke declined 4.2 percent.Deaths from Alzheimer's disease, diabetes, chronic lower respiratory diseases and accidents all declined 4.1 percent, according to the report.Deaths from flu and pneumonia fell 4.7 percent, and deaths from septicemia, a bacterial infection, decreased 1.8 percent, the report said.Deaths from homicides fell 6.8 percent, but suicides increased from 35,933 in 2008 to 36,547 in 2009. Other than suicide, which overtook septicemia as the 10th leading cause of death, the ranking of the leading causes of death was unchanged from 2008 to 2009, the report noted.Infant mortality hit a record low in 2009, falling from 6.59 deaths per 1,000 births in 2008 to 6.42, representing a 2.6 percent decrease, according to the report.The report, however, did not give reasons for these trends.Experts think behavioral changes, particularly the decline in smoking, are partly responsible for the improvements.The report's lead author Kenneth Kochanek, a statistician at the center, said this is preliminary data, and the final data, which should be available this summer, may shed some light on the findings.
