According to Jiangsu public news channel “news space station”, dangerous driving behaviors such as drunk driving and drunk driving have always been the targets of severe crackdown by traffic police departments. A few days ago, when the traffic police in Changshu, Suzhou, checked the drunk driving, the driver Zhang was arrested. What is unexpected is that Zhang is still on crutches while driving with wine. What is the matter?
At more than 11:00 p.m. on the day of the accident, the traffic police checked the driver of a white vehicle and found that the driver was suspected of drunk driving. Immediately, the police asked the driver to get out of the car and give him an alcohol breath test. Unexpectedly, the driver took out a pair of crutches from the co pilot’s position.
In response to media reports that more than 90 scientific researchers in the Institute of nuclear safety technology, Chinese Academy of Sciences (hereinafter referred to as the “Institute for nuclear safety”) resigned collectively, on July 16, a staff member of the personnel department of Hefei Institute of material science, Chinese Academy of Sciences, told surging news that more than 90 researchers collectively proposed to leave the Institute in June, “they all left voluntarily I have already completed the procedures for leaving the post. “
Institute of nuclear safety is a subordinate Institute of Hefei Institute of material science, Chinese Academy of Sciences.
The above-mentioned staff disclosed that more than 90 scientific research personnel were indeed poached, but their resignation was a normal flow of personnel.
On the same day, a researcher from the Institute of nuclear energy safety technology of the Chinese Academy of Sciences told the surging news that his resignation occurred last month and he did not know the specific reasons for his resignation and other relevant information.
On the 16th, media reports said that more than 90 scientific researchers of Hefei Institute of material sciences of the Chinese Academy of Sciences left. The report quoted an insider as saying that the departures were concentrated in the Institute of nuclear energy safety technology of Hefei Research Institute, most of whom graduated with doctorates and had a career establishment. All of them are within this year. The reason for leaving the company seems not directly related to the salary.
The staff of the personnel department mentioned above confirmed to the surging news that the news that more than 90 scientific research personnel had left was true. However, the above-mentioned media reports exaggerate the facts and “facts speak louder than words”.
According to the official website of the Institute of nuclear safety, Wu Yichan is the director of the Institute of nuclear safety technology, responsible for the strategic planning of the Institute. On November 22, 2019, the Chinese Academy of Sciences officially announced the results of the re election of academicians in 2019, and researcher Wu Yichan was elected as an academician of the Chinese Academy of Sciences.
On the 16th, surging news repeatedly called the relevant functional departments of the Chinese Academy of Sciences, but so far, no effective response has been received.
According to the information on the website of the Institute, the Institute is an Innovative Research Institute for basic, forward-looking and strategic research in the fields related to nuclear safety and advanced nuclear technology. Its goal is to build an internationally advanced basic research base for nuclear safety technology, an innovative high-end talent training center for nuclear safety, and a comprehensive support platform for safety technology of nuclear power plants and other nuclear facilities Third party evaluation institutions. The Institute is located on the science island of Hefei City, Anhui Province.
With the support of IAEA and ITER international cooperation program, national 973 / 863 program, national key R & D program, National Natural Science Foundation major program, national magnetic confinement fusion project and Chinese Academy of Sciences strategic pilot science and technology program, the Institute always pursues the concept of “ensuring nuclear safety from the source”, deeply integrates “research, learning and production”, and takes It has won a number of original scientific and technological achievements with world leading level. It has won more than 20 provincial and ministerial level scientific and technological awards, including the second prize of the National Natural Science Award, the first prize of the national science and technology progress award, the first prize of the national energy science and technology Progress Award, the first prize of the innovation achievement award of China’s industry university research cooperation, and the major scientific and technological achievement award of Anhui Province International awards include achievement award, international outstanding contribution award of fusion nuclear technology, etc.
British scientists have discovered novel coronavirus has evolved into 3 different strains during the spread of the world, and is “rapidly mutating to adapt to the immune system resistance of different populations”. Studies have also shown that virus variants found in some Americans are most closely related to viruses found in bats.
Researchers from Cambridge University mapped the initial spread of the new coronavirus (covid-19) in humans and found three different but closely related variants, the Sun reported on April 10.
Scientists have reconstructed the early evolutionary path of the new coronavirus, from the most affected areas in China to Europe and North America. The results were published in the latest issue of the proceedings of the National Academy of Sciences (PNAs).
Dr. Peter Forster, a geneticist at Cambridge University and the lead author of the research paper, said that through the analysis of the first 160 complete viral genome sequences found in patients, the closest variation found in bats was mainly found in patients from the United States and Australia, rather than in patients from Wuhan, China.
Three different strains of new coronavirus in global transmission
They used sample data collected from around the world between December 24, 2019 and March 4, 2020. Data show that there are three distinct but closely related variants of the new coronavirus, known as a, B, and C.
The researchers found that the closest type of coronavirus found in bats is type A, the original human virus genome. The virus genome exists in Wuhan, but it is not the main virus type in Wuhan.
The mutant a virus was found in the Americans living in Wuhan, and a large number of a virus was also found in patients from the United States and Australia.
The main virus type of Wuhan patients is type B, which exists in patients all over East Asia. However, if there is no further variation, it will not spread too much outside the region.
The researchers said the C virus, the main European type, was found in early patients from France, Italy, Sweden and the UK. The type C virus did not appear in the Chinese mainland samples in the study, but was found in Singapore, Hong Kong and South Korea.
The analysis also showed that one of the earliest routes of introduction of the virus into Italy was through the first recorded German patient on January 27, and the other early Italian route of infection was related to “Singapore clustering”.
The results show that type A virus is most closely related to the virus found in bats and pangolins, which the researchers describe as the source of the outbreak. Type B virus is derived from type A, separated by two mutations, and then type C, in turn, is the “daughter” of type B.
“Social isolation” can effectively inhibit the spread of the virus (on the left is the speed of transmission without measures, on the right is the speed of transmission with measures)
Foster said the virus had too many rapid mutations to track the entire covid-19 family tree. “But we use a mathematical network algorithm to visualize all plausible trees at the same time. What these techniques are best known for is the use of DNA to map prehistoric migration. We think it’s the first time it’s been used to track the infection of a coronavirus like covid-19. “
Experts warn that the new coronavirus is constantly mutating rapidly to adapt to immune system resistance in different populations.
Forster said their method could be applied to the sequencing of the latest coronavirus genome to help predict future hot spots in global disease transmission and surge.
The researchers used the phylogenetic network method to observe the evolutionary relationship between biological entities, so that hundreds of evolutionary trees can be visualized in a simple chart at the same time.
On the evening of April 6, Qilu Hospital of Shandong University issued an obituary, the full text of which is as follows:
Zhang Jing, the first group of medical aid team members in Shandong Province and the chief nurse of respiratory and critical medical department of our hospital, died at 18:58 on April 6, 2020 after a sudden cardiac arrest occurred when he was about to return home for rest after the expiration of centralized isolation medical observation according to the regulations. After the hospital organized the whole hospital’s experts and used all possible means to rescue and cure him, he failed.
During the rescue of Comrade Zhang Jingjing, all walks of life and netizens expressed their concern, love and blessing to her through various forms. We are deeply saddened and mourned for the tragic death of Comrade Zhang Jingjing and express sincere condolences to his relatives. We will properly deal with Comrade Zhang Jingjing’s aftermath.
Jiang Hongde, academician of the Chinese Academy of engineering and professor of Tsinghua University, died in Beijing on January 4 at the age of 78. Jiang Hongde was born in Hunan Province in 1942. He graduated from Tsinghua University in 1965 with a master’s degree from Graduate School of Chinese Academy of Sciences in 1981. He was elected academician of Chinese Academy of Engineering in 1999.
He has been engaged in the theoretical and experimental research, technical development and engineering application of the internal flow of turbomachinery for a long time, and has made great contributions to the technical progress of power generation equipment manufacturing industry and power industry in China. Once won the second prize of national science and technology progress award, and four provincial and ministerial science and technology progress awards. As a teacher, he often teaches students to be reassured by scientific research and focus on China: “as one of the national pillar industries, the energy industry’s market cannot be completely occupied by foreign countries, and it needs continuous independent innovation. It will take us more than ten years to create a gas turbine with independent intellectual property rights through digestion, absorption and innovation, and occupy a place in the market. This is a long process, which requires diligence, perseverance and perseverance, not to be tempted by the immediate interests, and finally to give the country a satisfactory answer. “
