VIENNA, Oct. 31 (Xinhua) -- Visiting Chinese President Hu Jintao met his Austrian counterpart Heinz Fischer here Monday and laid out a multi-point proposal to further strengthen bilateral cooperation.During the meeting, Hu spoke highly of the ties between the two countries, saying that China values its relations with Austria and is willing to join hands with Austria to elevate bilateral ties to a higher level.Then he proposed that the two sides enhance their political relationship based on equality and mutual trust, continue with their frequent high-level contacts and steer bilateral relations from a strategic and long-term perspective.The two countries should also expand their mutually beneficial economic and trade relations, he said, while calling for concerted efforts to fight trade protectionism and encourage mutual investment so as to achieve a balanced, diversified and sustainable trade relationship.Visiting Chinese President Hu Jintao (L) shakes hands with his Austrian counterpart Heinz Fischer (R) in Vienna, Austria, Oct. 31, 2011. Hu Jintao held talks with Heinz Fischer in Vienna Monday.China is willing to import more goods from Austria and to work with Austria to seek cooperation with third countries in Central and Eastern Europe, said the Chinese president, who also asked Austria to create favorable conditions for Chinese investors in Austria.Meanwhile, Hu urged Vienna to play a more active role in pushing for the EU's recognition of China's full market economy status and for a lift of the bloc's restrictions on high-tech exports to China.In the culture sphere, the two sides should promote people-to-people exchanges and boost cooperation in culture, eduction and media among others, Hu said.In addition, the two countries should also deepen cooperation in multilateral mechanisms to jointly push for a more just and fairer international political and economic order, Hu said.China, he added, is willing to enhance cooperation and coordination with Austria on important issues such as global economic governance, climate change, energy security and peaceful settlement of international disputes.History has proven that as long as the two sides understand and support each other, and respect each other's social systems and development models, the bilateral relationship can achieve long-term, steady and healthy development, Hu said.Fischer, for his part, said that he fully agrees with Hu's proposal, adding that his country is willing to enhance cooperation with China in culture, science and technology and tourism and expand coordination in the United Nations and other multilateral frameworks.

BEIJING, Nov. 3 (Xinhua) -- Two Chinese spacecraft accomplished the country's first space docking procedure early Thursday, silently coupling in space more than 343 km above Earth's surface.Nearly two days after it was launched, the unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 at 1:36 a.m., marking another great leap for China's space program.The success of the docking procedure makes China the third country in the world, after the United States and Russia, to master the technique, moving the country one step closer to establishing its own space station.A video grab taken from the China Central Television on Nov.3, 2011 shows the Shenzhou-8 spacecraft docking with the Tiangong-1 space lab module. Unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 early Thursday, according to the Beijing Aerospace Control Center.President Hu Jintao, who is in France for the G-20 summit, sent a congratulatory message on the success of the country's first-ever space docking."Breakthroughs in and acquisition of space docking technologies are vital to the three-phase development strategy of our manned space program," Hu said in the message.Hu said he wishes all the program participants to try all out to fulfill a complete success of the whole mission after the smooth docking.Other leaders, including Wu Bangguo, Wen Jiabao, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, who are Standing Committee members of the Political Bureau of the Communist Party of China Central Committee, watched the mission at the Beijing Aerospace Flight Control Center.China is now equipped with the basic technology and capacity required for the construction of a space station, said Zhou Jianping, chief designer of China's manned space program."This will make it possible for China to carry out space exploration on a larger scale," he said."The capability increases China's ability to act independently in space, as well as its ability to cooperate with others," said Gregory Kulacki, senior analyst and China project manager at the global security program of the Union of Concerned Scientists, a nonprofit scientific advocacy group based in the United States."China's pursuit of an original solution to space docking, that is based on their understanding of the experience of other nations, could lead to innovations or experiences other space-faring nations could find useful," Kulacki said.The world's first space docking was achieved in 1966, when the manned U.S. spacecraft Gemini 8 docked with an unmanned Agena Target Vehicle.Forty-five years later, the maneuver remains a technological challenge. Many of mankind's 300-plus attempts have been met with difficulties or resulted in failure."To link up two vehicles traveling at 7.8 km per second in orbit, with a margin of error of no more than 20 centimeters, is like 'finding a needle in a haystack'," Zhou said.The Shenzhou-8 and Tiangong-1 will separate after flying together for 12 days. After that a second docking procedure will be conducted.Rendezvous and docking, essential to exploring space beyond Earth's orbit, create the possibility of building space stations, resupplying them, transferring astronauts and rescuing them.Without this key know-how, exploration of the moon and beyond requires carrier rockets with significant amounts of thrust. China does not currently possess rockets of this magnitude.Shenzhou-8 and Tiangong-1 both weigh about 8 metric tons, well within the delivery capacity of the Long March 2F rocket. A permanent orbiting space station is designed to be as heavy as 60 metric tons, with docking ports accommodating both manned and freight space vehicles.The interior of both the Shenzhou-8 and Tiangong-1 is an actual environment in which astronauts can live and work. After the Shenzhou-8 tests, the Tiangong-1 will remain a target orbiter for more docking procedures in 2012 by the Shenzhou-9 and -10 spacecraft, at least one of which will be manned to conduct manual docking.Although the Shenzhou-8 is unmanned, it is equipped with devices to record images and data that will help China make improvements to its spacecraft design and astronaut training.Two female astronauts are now believed to be on the active duty roster for future Shenzhou missions, said Chen Shanguang, director of the Astronaut Center of China (ACC)."We must assess both male and female astronauts to verify if human beings can live in space, as there are huge differences between men and women in spite of their common generalities," Chen said."Space exploration activities would be incomplete without the participation of female astronauts," Chen said.The Chinese spacecraft also feature collaborative space experiments under the framework of a Chinese-German science and technology cooperation.German scientists designed bio-incubators for the experiments, while their Chinese counterparts were in charge of the development of control equipment, China's manned space program spokeswoman Wu Ping said.

SAN FRANCISCO, Nov. 12 (Xinhua) -- Apple has unveiled a worldwide replacement program for the first-generation iPod nano music player due to overheating battery issues, telling owners to stop using the product and get it replaced for free."Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Affected iPod nanos were sold between September 2005 and December 2006," said Apple in a notice posted late Friday on the support section of its official website.The company said the issue has been traced to a single battery supplier that produced batteries with a manufacturing defect. Since the product is five or six years old now, the likelihood of an incident increases.Owners of iPod nano can check the serial number on the back of the product to see if it is eligible for replacement. Apple promises a replacement unit about six weeks after the company received the affected one.The overheating battery issues of the first generation iPod nano have been known for years. In 2008, Japan's Ministry of Economy, Trade and Industry launched an investigation into Apple after dozens of iPod overheating cases were reported, including several incidents of iPod nanos toasting to the point of catching fire and causing minor burns to owners.Last August, a commuter train in Tokyo was delayed during rush hour when passengers complained of a strong burning smell from an overheating iPod nano that had burst apart.The portable music player also cost Apple a 22.5 million-U.S. dollar settlement in 2009 when a class action lawsuit in California alleged iPod nano is prone to scratches and its alleged defects were not disclosed by the company.

BEIJING, Oct. 14 (Xinhuanet) -- Materialism could be harmful to marriage, according to a new study published in the American Journal of Couple & Relationship Therapy Thursday.The researchers collected online "relationship assessment" questionnaires from 1,734 U.S. married couples.The questionnaire covered the topics about the couples' marital satisfaction, conflict patterns, marital communication, and marriage stability, and so on.Non-materialistic couples were about 10 to 15 percent better than those materialistics in their marital satisfaction, marriage stability and conflict levels, according to the study."What we found was a general pattern that materialism seems to be harmful to marriage," said study researcher Jason Carroll, a professor of family life at Brigham Young University.It didn't matter whether the materialistic spouse was the man or the woman, he added.However, materialism is not simply black-or-white: some couples can pursue their fortune and keep their relationship strong at the same time, the researcher suggested.But breaking their materialistic thought would be helpful for most couples, Carroll concluded.

HOUSTON, Dec. 13 (Xinhua) -- NASA Johnson Space Center on Tuesday formed a partnership with Texas's largest tech incubator and accelerator, the Houston Technology Center (HTC), to help reach its goals of increasing private and public collaboration.The strategic partnership is aimed at expanding HTC's mission of accelerating the growth of emerging technology companies in the Houston region to support NASA's goals of increasing private and public cooperation, the parties said in news release."We are excited to partner with NASA Johnson Space Center in an effort to foster entrepreneurial opportunities to the transitioning workforce in the Bay Area," said Walter Ulrich, CEO of Houston Technology Center."The combination of NASA's incredible technologies and HTC's powerful entrepreneurial resources presents the potential for immense economic development," he said.HTC is committed to growing a sustainable entrepreneurial network that will benefit the surrounding the space center for years to come including its future missions beyond low earth orbit. HTC will seed the future workforce through its close ties with the major universities and with science, technology, engineering, math programs and objectives, according to the news release.NASA and the Houston Technology Center began their partnership earlier this year when they originally formed plans to open an office to help former contractors near the Johnson Space Center.With the signing of the Space Act Agreement on Tuesday, the two sides move forward with retraining contractors and helping them get new jobs in the Houston area.An estimated 4,000 people are expected to lose their jobs when the space shuttle program is completed.
