Mngapa ristek kita makin loyo. Karena isinya, bukan kulit atau wadahnya. hehe
BAGAIMANA DI CHINA tahun yang baru lewat ? Remote Controlled Coal Mining Core technologies for remote controlled coal mining, a key project under the National 863 Program, was officially launched 2009 in Xi'an. The new technology will make real-time monitoring, failure diagnosis, and remote control of coal mining activities possible, and will provide core technologies for unmanned coal mining surface monitoring. According to a briefing, researchers have developed the core technologies for remote control of coal mining and digging processes, and associated equipment. The new technologies will allow a maximum remote control range between 500m and 1000m. With a budget worth RMB 24.34 million, the project will be completed in three years. It will raise China's coal mining equipment making capability to an internationally advanced level and improve coal mining safety in the country. Plasma Ignition for Power Plant Boiler Thanks to their 3-year efforts, researchers of the University of Science and Technology of China, Anhui Energy Group, and Anhui Tenglong Electric have jointly rolled out a plasma ignition system for power plant boilers. The new system is able to instantly ignite coal dust in the combustor, and release combustible gas, taking advantage of the high temperature flames produced by large power plasma arc. With the help of the combustor, the flame is boosted into the boiler for plasma ignition. Comparing with the conventional systems, the new system enjoys numerous merits, including a simplified ignition structure, stable plasma arcs, a longer electrode life, and raised thermal efficiency. The cathode has reached a work life of 200 hours in the test ignition of No. 5 boiler of Hefei Power Plant, or 4 times that of regular commercial cathode. The progressive flame booster developed in line with fluid dynamics is desirable for industrial applications, with enlarged application scope and raised reliability. It will not exceed the desired temperature, and will not sinter either, with stable progressive combustion. A 168-hour test run shows that the new ignition system consumed only one fourth the energy consumed by an oil ignition system. In addition, plasma ignition allows the operation of dust remover at the same time, greatly reduced the emission of particulate matters. The new technology will save more fuel oil, and produce fine economic returns and social benefits. Novel Internet Structure Granted with Patents QIAN Hualin, a research fellow at CAS Computer Network Information Center, has for the first time proposed a novel Internet structure that is able to address the unregulated networking and poor scalability of the existing Internet. He builds the novel Internet structure as a topological structure, allowing address space to be distributed by layer. The layer based structure can work as an IP router, resulting in a novel Internet structure with better performance, management, and control. The new Internet structure has recently passed the review of State Intellectual Property Office, and was granted with a national invention patent. The project has been so far granted with five invention patents by State Intellectual Property Office, including the patents for IPv6 address space separation and integration, short connect telecommunication, IPv4 accessibility to the layer based switch network, and control techniques for the layer based switch network. Additionally, the project team has produced a range of other results, including network protocols, standards, and associated algorithms, published a monograph named "the configuration of a layer based switch network", applied for two copyrights, and established an experimental platform for developing the prototype equipment for the new network. The said Internet structure will be deployed in the next generation Internet environment, and will soon get ready for commercial applications. Superconductor Material Has New Properties Prof. YUAN Huiqiu and his coworkers have recently found that iron based superconductor materials, such as barium-iron-arsenic, have an isotropic property in the low temperature upper critical magnetic field, indicating that the material has an upper critical magnetic field that is free from the impact of outside magnetic fields, entirely different from the phenomenon observed in a 2-D superconductor structure. The study also shows that though a crystal structure at a lower dimension is more desirable for the formation of high-temperature superconductors, it is not the sole factor contributing to the formation of such conductors. Researchers said that iron based superconductor materials have an electronic structure closer to the 3-D structure, though it is a 2-D crystal structure. The formation of iron based superconductors, therefore, can be explained by its unique electronic structure, indicating that it can be an important bridge to connect the low temperature heavy-fermion superconductors and high temperature cuprate superconductors. Researchers call for more study to understand the mechanism, as it is currently merely a new phenomenon. The finding, published in the recent issue of journal Nature, was jointly completed by Zhejiang University, Los Alamos National Laboratory, and Chinese Academy of Sciences Institute of Physics Pig's Adult Stem Cells Produce Better Skins A research team, headed by JIN Yan, Director of No. 4 Military Medical School Tissue Engineering Research Center, has created a pig based skin burn model to study the practicality of treating burn wounds using the artificial skins containing bone marrow stem cells. With the help of engineering technology and biomedical theory, researchers developed the artificial skins containing both natural materials and pig's adultbone marrow stem cells. The new artificial skins produce natural skins, while the bone marrow stem cells split into different skin cells to narrow down the burn wounds. The new technique expects to find applications in treating burn wounds. Researchers believe that the new technique may also be used to repair damaged joints or bones, if they can find right frames and stem cells. etc. etc. PROGRESS from minute to minute. GONG XI FA CAI.
