WINDHOEK, Nov. 29 (Xinhua) -- An agreement on Economic and Technical Co-operation was signed here on Tuesday between the Chinese and Namibian governments.The agreement was signed after Namibian Cabinet ministers and officials from various ministries held talks with Chinese State Councilor Liu Yandong, who arrived in Namibia on Tuesday for a three-day official visit.Minister of Presidential Affairs Albert Kawana, who is the Acting Director-General (DG) of the National Planning Commission (NPC), and Ambassador of China to Namibia Wei Ruixing signed the agreement.The two also exchanged letters on the provision of office supplies and solar energy equipment to the Namibian government by the Chinese government.During their talks, Liu highly spoke of the steady, healthy development of the relations between the two countries.She said the substantial cooperation have been obtained on agriculture, mining and human resources. Great achievements have been made in exchanges of culture and education.The state councilor also said China would like to work together with all African countries including Namibia to promote the development of people-to-people exchanges.Namibia's Deputy Prime Minister Marco Hausiku proposed future cooperation with China in visual and performing arts.He said the Directorate of Arts in the Ministry of Youth, National Service, Sports and Culture is keen to develop future relationships that will lead to bilateral exchanges in arts education, assistance in the development of small arts businesses, the promotion of arts through the exchange of information on arts and participation in events in the respective countries."This can be achieved through the development of ties between the relevant institutions responsible for these areas, such as the line ministries responsible for arts, arts education colleges, performance theaters, art galleries and organizers of events such as festivals and expos," he noted.He also encouraged exchanges between musicians in the sphere of composition, conducting, and instrumental playing in both folklore and symphonic genres, and therefore invited China in the development of Namibia's National Symphony Orchestra.Hausiku also proposed for scholarships in information and communication technology (ICT), particularly policy development and regulatory framework, and linkages with Chinese ICT institutions for exchange purposes.

WASHINGTON, Nov. 14 (Xinhua) -- A novel study in twins found that exposure to trichloroethylene (TCE) -- a hazardous organic contaminant found in soil, groundwater, and air -- is significantly associated with increased risk of Parkinson's disease (PD). Possibility of developing this neurodegenerative disease is also linked to perchloroethylene (PERC) and carbon tetrachloride (CCI4) exposure, according to the study appearing in Annals of Neurology on Monday.The National Institute of Neurological Disorders and Stroke estimates that as many as 500,000 Americans have PD and more than 50,000 new cases are diagnosed annually. While there is much debate regarding cause of PD, studies suggest that genetic and environmental factors likely trigger the disease. Several studies have reported that exposure to solvents may increase risk of PD, but research assessing specific agents is limited.The current epidemiological study, led by Samuel Goldman and Caroline Tanner with The Parkinson's Institute in Sunnyvale, California, investigated exposure to TCE, PERC and CCI4 and risk of developing PD. The team interviewed 99 twin pairs in which one twin had PD and one didn't, inquiring about lifetime occupations and hobbies. Lifetime exposures to six specific solvents previously linked to PD in medical literature -- n-hexane, xylene, toluene, CCI4, TCE and PERC -- were inferred for each job or hobby.The findings are the first to report a significant association between TCE exposure and PD -- a more than six-fold increased risk. Researchers also found that exposure to PERC and CCI4 tended toward significant risk of developing the disease. "Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Goldman in a statement.TCE, PERC and CCI4 have been used extensively worldwide, with TCE noted as a common agent in dry-cleaning solutions, adhesives, paints, and carpet cleaners. Despite the U.S. Food and Drug Administration (FDA) banning the use of TCE as a general anesthetic, skin disinfectant, and coffee decaffeinating agent in 1977, it is still widely used today as a degreasing agent. In the U.S., millions of pounds of TCE are still released into the environment each year and it is the most common organic contaminant found in ground water, detected in up to 30 percent of drinking water supplies in the country.In a release issued on Sept. 28, 2011, the Environmental Protection Agency announced that TCE is carcinogenic to humans.

TEL AVIV, Jan. 25 (Xinhua) -- Israeli Prime Minister Benjamin Netanyahu on Tuesday praised the relations between Israel and China at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between the two countries."We may be celebrating 20 years of relations, but our peoples are now celebrating a thousand years of friendship," Netanyahu said.He mentioned China's fair treatment towards the Jewish communities in the past, and the safe-haven given to them during the holocaust. "Like the Chinese people, the Jewish people have a long memory. We always remember our friends. We always remember people who extended a hand to us in our darkest days and we are grateful for China for that."Israli Prime Minister Benjamin Netanyahu (R) speaks at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between China and Israel in Tel Aviv on Jan. 24, 2012.The prime minister said that the friendship between the two sides can further deepen. "I think we barely scratched the surface of Israeli-Chinese relations. I have no doubt that in the coming years we'll see a dramatic expansion of these ties," he said."We've talked about doubling the trade (between the two countries). Well, I'd like to see a doubling of a doubling of the trade. I think Israel and China together are a winning combination, " Netanyahu said.In addition to the prime minister, several other senior Israeli officials attended the reception, among them ministers, former ambassadors and envoys to China and key figures in the bilateral ties.Chinese ambassador Gao Yanping said that "Over the past 20 years our pragmatic cooperation has been booming. When we started our diplomatic relations in 1992, our two-way trade volume was only a little bit more than 50 million U.S. dollars. Now the trade volume we have in two days equals that of the whole year of 1992."She said that "The further development of China-Israel relations is not only beneficial to both countries and the two peoples, but also very much conductive to regional stability, world peace and global prosperity.""Facing the ongoing major transformation and adjustment in the region and in the world, the China-Israel relationship is now at a new historical point. We should continue to work together, grow together and succeed together in the years to come," Gao added.

SAN FRANCISCO, Nov. 11 (Xinhua) -- Apple on Friday said it will "continue to investigate" the unexpected iPhone battery drain as some users still see the problems after downloading a latest software update designed to address the issues."The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues," said Apple in a statement made to technology news site AllThingsD.Apple released iOS 5.0.1, an update to its latest mobile operating system iOS 5 on Thursday. The update includes fixes for some bugs which are blamed for shortening the battery life of iPhones and other devices that use the system.Some users said the battery life of their iPhones look much better after the update. But according to some posts on Apple's official support forums, some iPhone owners still claimed the issue is persisting, saying they saw no difference at all after downloading the update.Complaints about the battery life of Apple's latest iPhone 4S smartphone have been piling up on the Internet in the past weeks.On Apple's official support forums, some iPhone 4S owners said their handsets' battery drained more than 10 percent every hour, even when in standby mode with some advanced features like Siri and location services completely deactivated.It is reported that Apple engineers contacted some iPhone 4S owners in Britain and installed a diagnosis file on their devices to send details back to the company's headquarters in Cupertino, California.Apple confirmed the iPhone battery issue last Wednesday, saying that a few bugs in the iOS system have caused the problem and it will release a software update in a few weeks.

BEIJING, Sept. 30 (Xinhuanet) -- The number of children being prescribed stimulants to treat attention deficit hyperactivity disorder (ADHD) has been steadily rising in the U.S. since 1996, researchers found.The finding was contained in a report released Wednesday in the U.S. medical journal Psychiatry.About 7.8 percent of children aged 4 to 17 in 2003 were diagnosed with ADHD, compared to 9.5 percent in 2007, according to the data gathered from the Health Resources and Services Administration's National Survey of Children's Health.And compared to 0.6 percent in 1987, 2.9 percent of children under 19 in 2002 have been prescribed stimulants, the report said.The finding raises the researchers' concern as stimulants have side effects such as decreased appetite, leeplessness and even heart-related damage, the report warned."Stimulant medications work well to control ADHD symptoms, but they are only one method of treatment for the condition. Experts estimate that about 60 percent of children with ADHD are treated with medication." says researcher Benedetto Vitiello, MD, of the U.S. National Institute of Mental Health."There is ongoing concern that these drugs may not be used properly, especially when they are prescribed to college students or children in their late adolescence who are more in charge of their care and may not be using the medications as prescribed." he added.
