BEIJING, Aug. 2 (Xinhuanet) -- The first close-up pictures of the asteroid Vesta, a protoplanet that dates back to the early days of the solar system, were revealed Monday by NASA scientists.The images were taken by the U.S. space agency's Dawn robotic probe, which is two weeks into a planned year-long survey of the second largest object in the main asteroid belt, located between Mars and Jupiter.About twice the size of California, Vesta is second in size only to Ceres, Dawn's next target and, along with Pluto, one of just five known dwarf planets. NASA is spending 466 million dollars to explore Vesta and Ceres during the course of a 10-year mission.Images from Dawn show Vesta a surprisingly diverse terrain and several unexplained geologic features. Chaotic terrain near the south pole is dominated by a towering central peak and huge ripple-like grooves stretching around its equatorial belt. Bright spots, dark pits and craters are filled with unexplained streaks of black and white debris. Terrain north of the grooves is much more heavily cratered.Scientists believe Vesta grew from a clump of gas and dust left over after the sun's birth some 4.65 billion years ago, a supernova explosion, which added radioactive materials to the growing body.Dawn will spend about a year circling Vesta, tweaking its orbit and altitude using an innovative technology called ion propulsion system, chief engineer Marc Rayman with NASA's Jet Propulsion Laboratory in California said.The ion propulsion system will enable Dawn to leave Vesta's orbit after a year of study and head off to Ceres, which is the largest object in the asteroid belt.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard (HP) on Monday unveiled a new business desktop computer, days after the world's largest personal computer (PC) maker announced its plan to sell its PC business.The company said the new model, HP Compaq 8200 Elite All-in-One Business Desktop, is the industry's first all-in-one PC that integrates Intel's second-generation Core vPro technology, which can deliver up to 40 percent better performance, 15 percent faster hard drive access and reduced downtime via remote information technology management."Another industry first in our Elite desktop family demonstrates our commitment to engineering excellence and underscores our global leadership in secure, enterprise computing, " Jeff Groudan, HP's director of commercial desktop marketing, said in a statement.HP said the new computer is available now in the United States. It starts at the price of 999 U.S. dollars, and comes with a standard three-year warranty.Last Thursday the company announced that it is considering a full or partial separation of its PC business through a spin-off or other transactions, a process that HP estimates may take about 12 to 18 months.

ISLAMABAD, Sept.4 (Xinhua) -- Pakistan's eastern Punjab province is in the grip of a dengue epidemic with dozens of cases being reported daily at various hospitals across the province, said officials and hospital sources.A report issued by the provincial health department on Friday said that as many as 145 cases of dengue fever in Lahore, the provincial capital, and several other cities have been reported in Punjab over the past three days.The total dengue fever cases in the Punjab are 1,419 since the beginning of this year, out of which 1,358 Dengue patients had recovered and been discharged from hospitals, according to local media.Dengue, an acute febrile disease spread by the bite of the aedes aegypti has been endemic in Pakistan for the last few years. It spreads most often after the rainy season in July and August when pools of standing water serve as ideal mosquito breeding spots.Gravity of the dengue disease was felt at the central level and Prime Minister Yusuf Raza Gilani extended full support to the Punjab government in coping with the growing number of cases of dengue fever.The Prime Minister, who was in Lahore on Friday, directed his Principal Secretary to contact the Punjab government and assist them in taking necessary preventive measures against the Dengue fever. He also asked him to extend offer on behalf of the federal government for provision of any technical expertise to the Punjab government.Acting on reports that the virus was spreading rapidly and that measures to control it had been unsuccessful, Punjab Chief Minister Shahbaz Sharif has presided over series of meetings and ordered the immediate suspension of the Lahore district health officer for failing to control the epidemic.A task force comprising a government minister, health officials and doctors has been set up to review the situation and suggest measures to curb the virus.On the orders of the chief minister, giant advertisements on measures that can be taken to prevent dengue have appeared in the media.People have been advised not to allow water to stand in containers, to use mosquito repellents, spray homes and be particularly vigilant at dawn and twilight when the dengue- carrying mosquitoes bite.This increase in public vigilance and awareness may yet halt the spread of a disease that over the past few weeks has struck across the province, said specialists.Meanwhile, the Health Department spokesman also stressed awareness among the people for prevention, control and treatment of dengue virus. According to him, the symptoms of dengue fever include high fever, severe body pain, itching and red spots, bleeding from nose and teeth and severe pain in the eyes. He said precautions include proper covering of the pots having water, like buckets and drums, and using coils, mats and sprays for eliminating mosquitoes.He further said dengue mosquitoes usually attack early in the morning from 6 a.m. to 9 a.m. and from 4 p.m. to 10 p.m.in the evening. The patients should act upon the advice of qualified physicians only, he maintained.

UNITED NATIONS, Sept. 19 (Xinhua) -- Mohammad Hossein Niknam, acting minister of health in international affairs of Iran, said here on Monday that his country is working to prevent and counteract the non-communicable diseases (NCDs), which have had significant effect on the population."NCDs have traditionally been more prevalent in affluent societies," he said. "However, they are increasingly becoming common in many developing countries, and in particular among the less affluent groups. The Eastern Mediterranean Region (EMRO) as others is suffering a heavy burden of NCD diseases and Iran is no exception: the total burden of disease for NCDs is 45 percent for males and 33 percent for females."Niknam's statements came as he addressed the UN General Assembly High-Level Meeting on Prevention and Control of Non- communicable Diseases."This timely high-level event provides us with an ideal platform to share views, information, ideas and experiences, to come up with remedial proposals and to forge effective collaborative partnerships in the implementation of realistic but effective health development programs in common areas of concern pertaining to the non-communicable diseases," Niknam said.He explained that Iran is implementing a series of programs in order to reduce the frequency and impacts of NCDs."As part of these programs I would like to mention prevention and control of common NCDs risk factors, imposition of taxes to curtail unhealthy habits such as tobacco consumption, execution of mass public information and educational campaigns, fostering food industry regulations, screening of blood pressure levels and high glucosemia," he said.Iran has created a Non-Communicable Diseases Risk Factor Surveillance System, according to Niknam. This system, in place since 2004, has conducted six large-scale surveys to gather information helpful to public health."Further, comprehensive cumulative national data has been compiled based on age, sex and location to facilitate effective monitoring and implementation of policies geared towards control and prevention of NCDs," Niknam said.Iran is conducting many other integrated NCD control and prevention programs, such as, to name a few, a Cardiovascular Diseases Control Program for rural areas; a National Cancer Control Program focusing on breast and colorectal cancers; and a Diabetes Control and Prevention Program that targets both rural and urban areas.Niknam ended his statement by noting that Iran has held regional consultations on the NCD issue."I would like to conclude my remarks by mentioning that as a sign of its commitment to promote regional and international cooperation, the Islamic Republic of Iran hosted on 25-26 October 2010 in Tehran the first regional meeting of a series of the regional consultations held by WHO (World Health Organization) on the prevention and control of NCDs," he said. "In our understanding, only through closer and meaningful collaboration at all levels, especially in areas such as legislation, resource mobilization and information and knowledge sharing, we may success in our endeavor to prevent and combat NCDs."

CANBERRA, Sept. 24 (Xinhua) -- Australian scientists on Saturday said a satellite due to re-enter Earth poses a negligible threat to life and property on Earth.U.S. National Aeronautics and Space Administration's Upper Atmosphere Research Satellite (UARS), which weighs more than five tons, is expected to re-enter the Earth's atmosphere at 1058 (AEST) on Saturday. The U.S.-based Center for Orbital and Re-entry Debris Studies estimates that re-entry could occur up to seven hours before or after this time.According to Nonathan Nally, a former editor of two space magazines and currently editor of the Australian Space News website, the satellite poses a negligible threat to life and property on Earth."Most of the satellite will burn up on re-entry, with perhaps as many as 26 stronger or harder small pieces surviving to reach the surface," Nally said in a statement."But with the majority of the Earth comprising oceans or uninhabited (or very sparsely populated) remote regions, the chances are overwhelming that any pieces of UARS that survive re- entry will fall harmlessly and never be seen again."Since the spacecraft is no longer powered, U.S. National Aeronautics and Space Administration has no control over where it comes down, but Nally said there is a small chance that debris from the satellite could land in Australia.Debris from SkyLab, another satellite which plunged to Earth, was scattered over parts of Western Australia in 1979. Skylab weighed about 77 tonnes, many times more than the UARS.?Dr Alice Gorman, a lecturer in the Department of Archaeology, specializing in space archaeology, at Flinders University in South Australia, said the UARS satellite re-entry is very reminiscent of Skylab in 1979."There is the same exaggeration of the hazard through the media, public anxiety as the advance warning allows for speculation, and a lack of understanding of what the risks actually are," he said in a statement."Should it land in Australia, we might expect the same rush for souvenirs as we saw with Skylab, as anything that has been in space has a special meaning on Earth."?UARS was launched on 12 September 1991 and decommissioned on 15 December 2005. Its total dry mass is about 5.5 tonnes. UARS is one of the largest NASA satellites to plunge back to Earth uncontrolled in the last 30 years.Since the beginning of the Space Age in the late-1950s, there have been no confirmed reports of an injury resulting from re- entering space objects.? Nor is there a record of significant property damage resulting from a satellite re-entry.
