BEIJING, Feb. 28 (Xinhua) -- Construction began on China's first low-speed maglev line Monday in Beijing, a project that will make China only the second country with a low-speed maglev line after Japan.The project marked China's ability to industrialize low-speed maglev technologies, said Chang Wensen, father of China's maglev technology and professor at the National University of Defense Technology.The 10-kilometer line runs from Shimenying Station in west Beijing's Mentougou District to Pingguoyuan Station in the Shijingshan District.The line, a section of Line S1 on the Beijing subway network, is expected to be completed in 2013 with a designed speed of 100 to 120 km per hour.China's research of maglev technologies was started in the 1980s by a team led by Chang Wensen. A 204-meter test line in central China's Hunan Province and a 1.5-km test line in north China's Hebei Province were built jointly by Beijing Maglev Technology Development Co., Ltd. and National University of Defense Technology.The intensity of the magnetic field had been tested as safe, according to a test report of Institute of Electrical Engineering, Chinese Academy of Sciences.The cost of the low-speed maglev line was estimated at 300 million yuan (4.6 million U.S. dollars) per kilometer, slightly more than light rail, but cheaper than the subway, which cost more than 600 million yuan a kilometer, said Li Jie, director of technology research center of National University of Defense Technology.The technology was also under consideration for Line 8 of the subway network in Shenzhen, in south China's Guangdong Province, said Liu Zhiming, board chairman of Beijing Maglev Technology Development Co., Ltd.."If Shenzhen adopts the technology, Line 8 will be China's second low-speed maglev line," he said.The world's first low-speed maglev line, at 8.9 km long, was completed in Japan in March 2005.Maglev, short for magnetic levitation, technology uses a large number of magnets to lift and propel a vehicle, making it faster, quieter and smoother than conventional wheeled transport systems.High-speed maglev vehicles can reach speeds of 450 km per hour and are usually used in long distance transportation, while low-speed maglev lines are usually used in short distance transportation.Construction also began on another seven lines on the Beijing subway network Monday.With an investment of 82 billion yuan (12 billion U.S. dollars), the eight lines will total 113.7 km in length and are expected to open from 2013 to 2015.Beijing has 16 lines under construction.

WASHINGTON, May 12 (Xinhua) -- Early initiation of antiretroviral treatment in people infected with HIV prevents them from transmitting the virus to their partners, according to findings released Thursday from a large-scale international clinical study.The study, known as HPTN 052, was designed to evaluate whether antiretroviral drugs can prevent sexual transmission of HIV infection among couples in which one partner is HIV-infected and the other is not. The results are the first of their kind from a major randomized clinical trial.Led by Myron Cohen, of the University of North Carolina, the research found that treating HIV-infected individuals with antiretroviral therapy (ART) when their immune systems are still relatively healthy led to a 96 percent reduction in HIV transmission to their partners.This critical new finding convincingly demonstrates that early treatment of infected individuals can have a major impact on the spread of the epidemic.Study investigators enrolled 1,763 couples who were not eligible for ART by WHO standards in nine countries around the world. All couples were at least 18 years of age. The vast majority of the couples (97 percent) were heterosexual, which precludes any definitive conclusions about effectiveness in men who have sex with men.Couples were randomly assigned to one of two study groups. In the first group, the HIV-infected partner initiated antiretroviral therapy (ART) as soon as the couple enrolled in the study (the immediate treatment group); in the second group, infected partners did not begin ART until their CD4+ counts fell to between 200 and 250 cells/mm3 or they developed an AIDS-related illness (the delayed treatment group). Couples in both groups received HIV primary care, counseling and condoms.Results of this research study, which was scheduled to conclude in 2015, are being released early, after the independent data and safety monitoring board (DSMB) determined that the benefits of early treatment were clear.

CARACAS, March 30 (Xinhua) -- The number of confirmed cases of the A/H1N1 influenza in Venezuela has risen to 482 this year, Health Minister Eugenia Sader said on Wednesday.According to the latest report, the state of Merida in southeastern Venezuela has 189 A/H1N1 influenza cases, the biggest number ever reported, which was followed by the Capital District of Caracas with 112 cases. The other 181 cases were confirmed in 17 of 24 Venezuelan states.The first case for this year was reported in Merida earlier this month.Sader said that the Venezuelan government was trying to prevent the spread of the disease. Some 3 million people have been vaccinated against the virus.Three patients infected with the A/H1N1 influenza virus have died in the country this year, according to Sader.The A/H1N1 influenza can cause deadly pneumonia if it is not treated early.

CAPE TOWN, April 30 (Xinhua) -- The World Economic Forum on Africa, scheduled on May 2-4 in Cape Town, South Africa, will see participants exchange views on how the continent can turn to the next chapter of development.The meeting, expected to gather a record 900 participants from over 60 countries, will be held under the theme "From Vision to Action, Africa's Next Chapter," organizers said."We chose this theme because we feel it is very relevant for the events that are taking place on this continent, and the opportunity for growth and investment that the international and African communities are seeing," said Katherine Tweedie, head of Africa for the World Economic Forum.Seven of the fastest growing economies in the world in the next five years will be in sub-Saharan Africa, Tweedie noted, saying that a lot of discussion will be devoted to explore drivers behind this growth.Africa's economic growth in recent years have impressed the world. Though being the most underdeveloped continent, Africa have been more resilient than expected during the global economic crisis.The International Monetary Fund (IMF) have predicted that the continent's growth in 2011 will reach 5.3 percent.Under one of the three thematic pillars, "Shaping Africa's Role in the New Reality," the meeting will explore how Africa can take on a leadership role in the new reality and guard against newly emerging global and regional risks. Participants will look at how Africa can strengthen its representation and negotiation capacity on global platforms such as COP 17 and the G20.Meanwhile, the meeting will look into Africa's industrial diversification, which is widely considered as an effective way to increase competitiveness. Discussions under the thematic pillar of "Fostering Africa's News Champions of Growth" will focus on what innovative and entrepreneurial lessons drive Africa's fastest- growing companies, and how can Africa's emerging economies build capacity in science, technology and innovation to move up the value chain.Another topic expected to attract much attention is Africa's inclusive development. In recent years, African decision makers have been looking for ways to attain inclusive development by translating economic growth into better lives for the people.Marcus Courage, managing director of consulting group Africapractice, said ahead of the meeting that Africa must start measuring its economic growth in terms of job creation and progress of value addition of what it produces, rather than the gross domestic product (GDP), if it has to move from vision to action."One of the challenges is that we measure economic success in therms of GDP. That is not fair reflection of action," he told Xinhua.Under the thematic pillar of "Building Partnership for Inclusive Development," participants will debate on how can inclusive growth be put at the heart of a sustainable development agenda for Africa, and how can government of African countries work together with the business sector to distribute more equitably the benefits from the wealth in natural resources, among others.Regarding the highlight of this year's meeting, Tweedie said there will be a strong focus on green growth and the environment agenda, working closely with the South African government, given that South Africa will be hosting the COP 17 meetings in December.The meeting will also have very strong representation from Francophone west Africa for the first time. As a result a good part of the discussions will be focusing on issues taking place in this part of Africa, she added.Although South Africa has hosted the World Economic Forum on Africa for a number of times, this year the host is attracting particular attention.South Africa has joined the BRICS group of countries which also include Brazil, Russia, India and China, becoming the only African member in the grouping. It is also the only country from Africa in G20. In November this year, South African city of Durban will host the 17th Conference of the Parties (COP 17) to the UN Framework Convention on Climate Change.How can the country speak for Africa in the international arena, and what role can it play in facilitating closer cooperation between developing countries is also expected to draw in-depth discussions at the meeting.Meanwhile, participants are also expected to exchange views on issues including Africa's agriculture development, infrastructure construction, China-Africa cooperation, impact of political situation in North African and the Middle East on Africa's economic development, among others.
