BEIJING - Chinese researchers have developed a device to conduct marine positioning with high accuracy, according to the Science and Technology Daily on Friday.The device was disclosed at a science forum in Northeast China's Heilongjiang province. The researchers from Harbin Engineering University monitored and collected data from 200 observation stations and independently developed the navigation positioning device to within one meter accuracy, the newspaper said.It can fully support domestic made high-end devices for oil exploitation, laying pipelines, searching and salvaging, and offshore wind power.The device is under the BeiDou navigation system. Named after the Chinese term for the Big Dipper constellation, the BeiDou project was formally initiated in 1994.It began to serve China in 2000 and the Asia-Pacific region at the end of 2012. wristbands for eventsrubber bracelets canadacustom rubber wristbands canadaimprinted rubber braceletssilicone wristbands australia
[Photo/VCG] A cancer patient with HIV may have been cleared of the virus after receiving a bone marrow transplant from an HIV-resistant donor, thought to be the second such case after a bone marrow transplant, according to research published in the journal Nature on Tuesday. The patient, whose identity was not disclosed, stopped taking antiretroviral drugs 16 months after the transplant, and the virus has not been detected during an additional 18 months, according to the study. In the research, led by Ravindra Gupta, an infectious diseases physician at the University of Cambridge in the United Kingdom, the patient received bone marrow stem cells from a donor with a rare genetic mutation known as CCR5 delta 32, which produces immunity to HIV infection, according to Nature. The first such case of an HIV patient being cleared of the virus after a bone marrow transplant happened a decade ago to Timothy Brown, known as the Berlin patient, who is still free of the virus. The breakthrough suggests the first case was not a one-off and could pave the way for future treatments, Nature said in a release on its website. Gupta described his patient as functionally cured and in remission. But he cautioned, It's too early to say he's cured, according to a Reuters report. The procedure is expensive, complex and risky, and will not be a common method to cure all patients with HIV, the report said.
