SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.

XI'AN, Nov. 20 (Xinhua) -- Fish in Hongjiannao Lake, China's largest desert freshwater lake, are teetering on the verge of extinction, according to local fishery authorities."The fish in Hongjiannao have nearly vanished," said Li Weiping, the head of a fish monitoring station in northwest China's Shaanxi province.As the lake continues to shrink, its water has become more salty and its pH reading has reached 9.6, while the maximum reading suitable for fish is 8.5, according to Li.The lake has gradually lost the water that it used to get from underground streams and rivers, Li said, adding that excessive coal mining around the lake has changed the way water flows underground. Two reservoirs have been built on two rivers near the upper reaches of the lake, preventing river water from flowing into the lake.The lake's water level has plunged by 20 to 30 centimeters every year. Its total surface area has been reduced to 41.8 square km, down from 67 km in 1996.
