JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.

CAIRO, Jan. 23 (Xinhua) -- As part of bilateral efforts to enhance cultural cooperation between the two great civilizations, China, as the Guest of Honor, will participate in the 43rd Cairo International Book Fair in Egypt."An outstanding Chinese delegation will attend the fair to inform the Egyptian people all about Chinese culture," said Chen Dongyun, cultural counsellor of the Chinese Embassy in Egypt.Some 248 publishers, 13 renowned scholars, writers and artists will display about 10,000 books about the achievements made by China in various fields such as politics, economy, science and technology, and culture.The fair, the most important of its kind in the Arab region, will be held on Jan. 29 through Feb. 8 in the Cairo International Conference Center. The annual fair began in 1969.The Chinese hall in the center covers an area of 1,400 square meters, with special areas allocated for a variety of exhibitions about the history of the evolution of Chinese characters, photos reflecting Sino-Egypt friendship and landscape of modern China and intangible cultural heritage.The fair also includes a seminar featuring literature and translation among Chinese and Egyptian writers and artists and a week-long film show in which six Chinese films with Arabic subtitles will be introduced to the audience.Chinese participation reflected the common consensus of the leaders of the two countries to deepen mutual understanding and friendship and will serve to promote the sound and sustainable development of bilateral relations, Chen said.Zhang Jichen, vice president of China National Publications Import and Export (Group) Corporation, which is in charge of the organization of the Chinese activities at the fair, said a cooperation agreement between the General Administration of Press and Publication of China and Egypt's Ministry of Culture.China will also present some 1,000 high-quality books to the National Library and Archives of Egypt and the Alexandria Library.The fair is expected to attract 632 publishers from 29 countries, including 17 in the Middle East. More than two million visitors participate in the fair each year.

JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

STOCKHOLM, Feb. 20 (Xinhua) -- The exhibition of the Chinese Terra-cotta Army here was an enormous success, project organizer Sanne Houby-Nielsen said Sunday.About 320 objects, including terra-cotta warriors from the ancient Chinese Qin Dynasty and other terra-cotta figures from Han Dynasty, were exhibited at the Far Eastern Antiquities Museum during the event, which ended Sunday.Houby-Nielsen, who is director of the museum and also director-general of the country's National Museums of World Culture, told Xinhua in an exclusive interview that the total number of visitors was around 350,000, more than double the expected turnout.This was the highest number of visitors the museum has ever experienced in its history since it was established in the 1940s, said Houby-Nielsen, adding that the exhibition was originally scheduled to end on Jan. 16, but "a great pressure from the audiences" prompted the museum to extend it till Sunday."It is an exhibition which won the most audience for many years in Sweden. We feel particularly happy because it was a very good display of the story of the first emperor and the early Han Dynasty," she said."We felt such a huge interest that we have to prolong it. So we were very grateful that it was possible to prolong the exhibition," she added.The exhibition was declared open by Swedish King Carl XVI Gustaf in August. Many of the ancient Chinese artifacts have never been exhibited outside China.Swedish Sinologist Cecelia Lindqvist commented that the event helped people understand the current China by looking at the history of China presented in the exhibition.

HARBIN, March 2 (Xinhua) -- A therapeutic apparatus to treat Parkinson's disease has been developed in northeast China's Heilongjiang Province, according to the provincial science and technology department. It is a worldwide breakthrough in treating the disease with transcranial magnetic stimulation, concluded an expert panel with the Heilongjiang Provincial Department of Science and Technology.The team said it came to the conclusion after evaluating technical documents and clinical test results Monday.This is the first time that transcranial magnetic stimulation has been adopted to treat Parkinson's disease, said Sun Zuodong, chairman of Aobo Medicine Apparatus Co., Ltd. (AMA), the developer based in the provincial capital Harbin.Transcranial magnetic stimulation is a noninvasive method which causes depolarization in the brains' neurons so as to restore the functions of brain nerves.The apparatus consists of three parts, namely brain wave stimulator, field effect cap and multiplier, said Sun.Clinical tests over more than 100 patients showed that the apparatus had a 70 percent success rate in reducing the disease's symptoms, according to Wang Aili, planning manager of AMA.The new equipment will help generation of dopamine, the reduction of which within the brain caused the disease, said Wang Weixiang, a consulting doctor with the Heilongjiang Provincial Rehabilitation Hospital.Parkinson's disease is a disorder of the neural system, which leads to limb tremors and difficulty in walking and other movements.China has 2 million patients suffering from Parkinson's disease, mostly people over the age of 50, and the number is increasing by 100,000 annually, said Dr. Wang.
