BUJUMBURA, May 31(Xinhua) -- As the World No Tobacco Day is celebrated on Tuesday, many Burundians feel happy that they have given up smoking thanks to herbal drugs.Evariste Ndikumwami, 55, residing in the Burundian capital Bujumbura, said he had been smoking for 30 years, but gave up smoking in January after taking herbal drugs prescribed by an abbot."I had been smoking since my teenage and I gave up smoking in January (this year) after I took herbal drugs that I got from a Roman Catholic priest from Uganda working at Rugari parish in the province of Muyinga, some 210 km northeast of the Burundian capital Bujumbura," Ndikumwami told Xinhua.Ndikumwami said he used to smoke a pack of 20 cigarettes per day, adding that he had found it hard to give up smoking.He said, "I took the herbal drugs for 15 days. The abbot prescribed me two herbal drugs -- one to be smoked for five days at daytime when I desire to smoke and another one to be applied around the nostrils at night."After the medication period, he never felt the desire for smoking cigarettes, he said."When my friends realized I was no longer smoking, they asked me which drugs I took to give up smoking. I directed them to the abbot who had healed me and they also got cured and stopped smoking," Ndikumwami said.

MOSCOW, June 27 (Xinhua) -- Russia successfully launched a Cosmos class military satellite on Monday, said spokesman of the Russian Space Forces Alexei Zolotukhin.A Soyuz-U carrier rocket carrying the military satellite blasted off from the Plesetsk Plesetsk space center in northern Russia at 20:00 Moscow time (1600 GMT), Zolotukhin said."The rocket put the Cosmos series military satellite into the designated orbit at 20:08 Moscow time (1608 GMT)," he added.The spokesman also said the launch of the Soyuz-U carrier rocket "was the first time for this type of rockets" in this year.The launch carried out by a team from the Russian Space Forces was supervised by Space Forces Commander Oleg Ostapenko.The satellite, Cosmos-2472, is a new member to a Russian network of about 60-70 military reconnaissance satellites.

BEIJING, Sept. 9 (Xinhua) -- Lenovo Group, China's largest PC maker, said it aims to become the world's second-largest PC provider by the end of this year, China Daily reported Friday.The PC maker will take aggressive action to expand in the international PC market left by its competitors because of strategy adjustment, the English newspaper quoted Liu Chuanzhi, the board chairman of Lenovo, as saying.A few weeks ago, the world's biggest PC maker Hewlett-Packard Corp. said it will spin off its PC sector. Apple Inc's former CEO Steve Jobs resigned."The Chinese market is the starting point for Lenovo, but it won't be the only place Lenovo should put emphasis on. We will set up a more active strategy for expanding in overseas markets," Liu said.The PC maker has long been focusing on the global market. It purchased the PC division of the IBM Corp. a few years ago. In January, it announced a 175-million-U.S.-dollar joint venture with Japan's NEC Corp. In July, Lenovo completed its acquisition of Medion AG, a German multimedia and consumer electronics maker.

WELLINGTON, Aug. 8 (Xinhua) -- A New Zealand study has found that people who work at least 50 hours a week can be up to three times more at risk of alcohol problems than people who work fewer hours.The study, conducted by the University of Otago, used data that followed more than 1,000 people born in Christchurch in 1977 through to age 30.Study leader Dr Sheree Gibb said it aimed to examine whether working hours were related to alcohol problems in early adulthood.Data from more than 1,000 participants at ages 25 and 30 showed a significant association between longer working hours and alcohol- related problems.Longer working hours were associated with higher levels of alcohol problems including frequent alcohol use and alcohol abuse or dependence.People who worked 50 hours or more on average a week were 1.8 to 3.3 times more likely to have alcohol-related problems than those who were not working, and about 1.2 to 1.5 times more likely to have alcohol-related problems than those who worked 30 to 49 hours a week.The higher risk of alcohol abuse for those who worked longer hours was evident in both men and women, according to the study.Gibb said the finding could suggest a need for consideration of policies and programs targeting individuals who worked long hours, with the aim of reducing rates of alcohol-related problems.The article had been accepted for publication by the UK-based journal Addiction.

WASHINGTON, June 2 (Xinhua) -- When humans see red, their reactions become both faster and more forceful, according to a new study published this week in the U.S. bimonthly journal Emotion.The findings may have applications for sporting and other activities in which a brief burst of strength and speed is needed, such as weightlifting. But the authors caution that the color energy boost is likely short-lived.The study measured the reactions of students in two experiments. In the first, 30 fourth-through-10th graders pinched and held open a metal clasp. Right before doing so, they read aloud their participant number written in either red or gray crayon. In the second experiment, 46 undergraduates squeezed a handgrip with their dominant hand as hard as possible when they read the word "squeeze" on a computer monitor. The word appeared on a red, blue, or gray background.In both scenarios, red significantly increased the force exerted, with participants in the red condition squeezing with greater maximum force than those in the gray or blue conditions. In the handgrip experiment, not only the amount of force, but also the immediacy of the reaction increased when red was present.The colors in the study were precisely equated in hue, brightness, and chroma (intensity) to insure that reactions were not attributable to these other qualities of color."Red enhances our physical reactions because it is seen as a danger cue," explains coauthor Andrew Elliot, professor of psychology at the University of Rochester and a lead researcher in the field of color psychology. "Humans flush when they are angry or preparing for attack," he explains. "People are acutely aware of such reddening in others and it's implications."But threat is a double-edged sword, argue Elliot and coauthor Henk Aarts, professor of psychology at Utrecht University, in the Netherlands. Along with mobilizing extra energy, "threat also evokes worry, task distraction, and self-preoccupation, all of which have been shown to tax mental resources," they write in the paper.In earlier color research, exposure to red has proven counterproductive for skilled motor and mental tasks: athletes competing against an opponent wearing red are more likely to lose and students exposed to red before a test perform worse.
