　　CCTV News:On April 28th, the State Council Press Office held a press conference to introduce the "Three-year Action Plan for National Special Rectification of Work Safety" and answered questions from reporters.

　　The reporter asked, some localities and enterprises have a weak concept of safe development, a weak sense of red line, and attach importance to development and light safety. How can we reverse this concept and what are the arrangements for the three-year action plan?

　　Shen Zhanli, spokesperson of the Emergency Management Department and director of the Press and Publicity Department, introduced that, first, party committees (party groups) at all levels are required to arrange special study. Combined with the actual situation of the local industry, study and implement measures.

　　The second is to organize safety supervision cadres, enterprise leaders and safety management personnel to conduct batch rotation training. This year, the emergency management system will organize a lecture hall on safety production throughout the year, and other departments and localities will carry out various safety production lecture hall activities in combination with the actual situation. Through leading cadres’ lectures, in-depth lectures by experts and scholars, and interactive lectures by front-line staff, the concept of safety development will be truly rooted in the hearts of the people and can be effective.

　　The third is to carry out regular and systematic publicity and education activities. Recently, the the State Council Safety Committee Office will issue a "five advances" work plan to promote safety publicity, so as to promote safety publicity to enter enterprises, rural areas, communities, schools and families, popularize safety knowledge and cultivate safety culture. At the same time, various media channels are used to widely publicize the principles, policies, laws and regulations of safety production, expose typical cases of violation of laws and regulations, and create a social atmosphere in which safety production must be alarmed, persistent and unrelenting.

　　Only by tightening the ideological "master switch", grasping the "bull’s nose" of the responsibility system for production safety, and setting up the "high-voltage line" governed by law, can we truly hold the bottom line and red line of safe development, thus achieving safe development and high-quality development.

　　A Burmese bought ofo and oBike bicycles that were abandoned overseas and donated them to poor children. On June 20th, a batch of modified bike-sharing was sent to a rural school near Yangon. Local students no longer need to walk far to school every day. This is undoubtedly a blessing for those abandoned bike-sharing.

　　Two years ago, bike-sharing was the darling of capital, and the number of bike-sharing in the city was increasing day by day, and eventually it was surplus; A year ago, when the wind blew away, some entrepreneurs who were swimming naked faded, and there were fewer and fewer players in bike-sharing, leaving only abandoned bicycles and bicycle cemeteries. It is estimated that by 2020, at least 10 million bike-sharing vehicles will be scrapped, which will not only occupy public space and land resources, but also produce at least 160,000 tons of municipal waste. So, where have all those deserted bike-sharing gone?

　　donate

　　Non-profit organizations buy bicycles

　　Donate it to Burmese students after transformation.

　　According to foreign media reports, Mike, a foreign entrepreneur, founded a non-profit organization called LessWalk, bought 10,000 bicycles from enterprises in bike-sharing, and plans to donate them to students in Myanmar.

　　In rural Myanmar, it is very common for students to walk a long way to get to school. Some students walk from home to school for more than an hour every day. Many families can’t afford bicycles or motorcycles, and school buses are unheard of for these children.

　　LessWalk made a simple transformation on the bought bike-sharing, added a back seat to them, converted the QR code scanning lock into a common key lock, and then transported them to Myanmar. Most of these bicycles were purchased from liquidators, who controlled oBike’s closed business in Singapore and inherited ofo’s abandoned fleet, which made their purchase price cheaper than ordinary bicycles.

　　At the end of April, the first batch of 3,300 bicycles arrived in Myanmar, and on June 5, another 1,000 ofo bicycles were delivered to the warehouse in Yangon. Mike said that they bought a total of 4000 bicycles from ofo.

　　He said that the average price of bicycles is about S $20 (about RMB 100). Together with transportation, modification and distribution costs, the cost of each bicycle is about 35 US dollars (about RMB 240 yuan). He bought 5000 cars out of his own pocket, and the other half was sponsored by sponsors. Mike hopes to call on friends from all over the world to join his plan to "regenerate" hundreds of thousands of abandoned bicycles.

　　Ofo’s branch in the United States announced in mid-2018 that it would shrink its related business in the United States. A spokesman for ofo in the United States declared: "They will not be thrown into the garbage dump. We hope to leave these little yellow cars here and give them to people who need them." Ofo said that more than 40,000 small yellow cars it put into use will not be abandoned on the streets, nor will they become urban garbage and occupy public resources. At present, it has donated about 3,000 bicycles to local communities and charitable organizations in 10 evacuated cities. In the future, ofo will donate more cars in more cities.

　　After ofo withdrew from India, bicycles were recycled by Bounce, a shared scooter company. After ofo announced the closure of business in Israel and other Middle Eastern countries, it also donated bicycles to local charities.

　　retrieve

　　Sorting bicycles that have reached the scrapping cycle.

　　Ofo promotes recycling

　　In China, ofo claims that bike-sharing has a complete recycling process to ensure that obsolete vehicles can be effectively disposed of.

　　Not long ago, some media reported that thousands of ofo sharing bicycles cars were crushed into scrap iron in a demolition factory in Xuefu Section 2, Wuhou District, Chengdu, and then recycled and transported away by the scrap factory at the price of 15 yuan per car. The relevant personnel of the scrap factory said that there were about 3,000 small yellow cars at the scene.

　　The small yellow car with an ex-factory price of several hundred yuan was eventually sold as scrap iron, and many people expressed "distressed". In this regard, the relevant person in charge of ofo responded that the scrapping clean-up is under the supervision of the government, and the normal management behavior of enterprises on vehicles involves only a very small part of the amount of vehicles put into Chengdu, which has reached the retirement age.

　　Last year, ofo said that it had reached a strategic cooperation with Beijing Vanke, China Circular Economy Association and Beijing Urban Renewable Resources Service Center to promote the recycling of used bicycles, so as to recycle the bike-sharing that has reached the end-of-life cycle and realize the green closed-loop management of the whole life cycle from production, use to recycling.

　　transboundary

　　Mobike made furniture and runways.

　　Realize 100% recycling.

　　On Earth Day on April 22nd this year, mobike and YUUE Product Design Studio in Berlin jointly released a group of creative cross-border cooperation to turn bicycle parts into furniture products, such as recliners, vertical lights, coffee tables, desktop finishing racks, candlesticks, etc. All the raw materials of these furniture are from discarded parts in mobike, which shows the new achievements of mobike’s "life cycle" plan.

　　For example, the mobike classic front fork was transformed into a desktop finishing rack: the front fork has its own internal criss-crossing reinforcing ribs, which naturally divides the container into several parts. The connection between the added PC material and the front fork makes full use of the original screw holes, just like the mortise and tenon structure, and a desktop finishing rack with fashionable appearance and practical function was born.

　　"mobike will be scrapped one day after serving for thousands of kilometers. Although every mobike’s materials can be recycled through recycling, we hope that they can be revived through simple transformation, which is also a more environmentally friendly and energy-saving measure. " Qin Hao, a senior expert on sustainable development in mobike, said. In July 2018, mobike took the lead in putting forward and actively practicing the concept of life cycle environmental protection in the industry. In the whole process of design, procurement, production, delivery, operation and scrapping, the "3R principle" (Reduce, Reuse and Recycle) was implemented, and the used bicycles were 100% recycled, realizing energy conservation and environmental protection in the whole life cycle of mobike.

　　Not long ago, a plastic multifunctional playground made of waste tires from mobike was laid on the playground of Wanhua School in Yan ‘an. According to reports, the particles donated to the plastic site come from the waste tires recycled in mobike, all of which are solid polyurethane tires made of polyurethane materials specially developed by Dow Company. This is another use of recycling in bike-sharing.

　　According to the introduction of mobike, the maintenance records of each vehicle’s components are recorded on the intelligent life cycle management platform in mobike, which can clearly trace the service life of each component, and optimize the design and production of vehicles according to the maintenance records, so as to improve the service life of vehicles and reduce the resource consumption and carbon emissions caused by maintenance. Among them, smart locks, solar panels and wheelsets will be recycled and reused after passing the test. As of a year ago, mobike had recycled more than 300,000 tires in cooperation with manufacturers.

　　In addition, mobike cooperated with China Renewable Resources Development Co., Ltd. and Tianjin Xinneng Renewable Resources Co., Ltd. to provide mobike with professional services such as recycling, dismantling and harmless treatment after the end of bicycle life cycle.

　　transform

　　Hello, waste wheels become cat nests.

　　Recycling according to material differences

　　Not long ago, at the scene of a public welfare activity, the stray cat nest made by parents and children with bike-sharing’s used wheels was very eye-catching. The bottom of the nest formed by overlapping tires ensures a certain distance from the ground, which can not only prevent the nest from being soaked in rainy days, but also increase its own weight and make the nest not easy to topple; The nest is made of three wheels, leaving room for stray cats to move, and waterproof cloth is wrapped to effectively block strong winds and rain.

　　In fact, since last year, Harrow Bicycle has transformed some bicycle waste wheels into stray cat nests, and placed them in the places where stray cats often appear on campus, giving them a warm home in winter.

　　Hellobike said that it will sort and recycle bicycle parts according to their material differences. Metal materials such as the main frame are recycled to make metal ingots for recycling, and the plastic of the car body is granulated for secondary processing, and the parts that cannot be completely decomposed, such as tires and cushions, are treated scientifically and harmlessly.

　　Recently, the game industry is really surging. One minute, the Shanghai Free Trade Zone is established, and the game console is expected to be lifted. The magazine Home Computers and Games is suspected to be closed. The impact of these two events has not dissipated, and suddenly the news that Perfect World will acquire video game buses and game websites and forums such as A9VG and CNGBA has aroused a thousand waves, which has aroused the heated discussion of countless players and media attention. Related analysis can be described as numerous and endless, but many analyses only see a certain point, but fail to see the whole face, that is, the whole picture of the whole thing. What the perfect world has done is actually done grandly, Tencent is doing it, and Sohu Changyou has already done it.To put it simply, these domestic game makers and giants are all seeking diversified development and want to become a comprehensive and diversified entertainment empire.

A ripple

The perfect world is looking for a new breakthrough

　　Perfect World, a company with many products in the field of online games and infinite crazy in-house purchases, has been getting along well in recent years, with great profitability and capital. If nothing else, the game "Saint OL" that Perfect World spent a lot of money to build was heroic when it first came out, and it spread soft articles and did related activities everywhere, which quite swept the world. As a result, the market response was not good because of the poor quality of the game, and then it was almost completely abandoned in Perfect World.

The perfect world is not short of money.

　　Since there is no shortage of money, it will definitely not count money at home every day. One of the characteristics of capitalism is that capital has a natural impulse to accumulate. That is to say, no matter individuals or companies, as long as they have certain funds, they want to earn more money and accumulate more funds.So since the perfect world is not short of money, of course, it has to play some tricks.

　　What tricks should we play? I’ve basically played all the tricks I should play in online games, and it’s hard to play new tricks, but some tricks other than online games haven’t been played yet. Have you noticed that Shanda made a grand box when it was arrogant in the past, bought a starting point, and then made an e-book? Then Tencent, which has all kinds of businesses, besides games and websites, and Weibo, also has WeChat. Look at Sohu Changyou over there, which bought 17,173 online games as early as 2011.

17173 has long been acquired by Sohu Changyou.

　　Therefore, when Perfect World saw these situations, it must think something in its heart. It is also a domestic first-line game manufacturer, and it has not played in other fields except online games. Since everyone is playing diversified integration, we can’t lag behind. As a result, Perfect World announced its own game platform ARC several months ago, and then recently it was reported that Perfect World acquired a series of TV game websites such as video game buses.

　　So to put it bluntly, the perfect world is actually seeking a new breakthrough and engaging in diversification strategy, and these tricks of the perfect world are not new. Let’s say this ARC platform, STEAM has done it, and Sohu Changyou has also played it. Then it is said that the perfect world will launch its own TV box in the future, which is also grand.

The ARC platform is not new.

　　In fact, a series of actions of Perfect World are very similar to those of Shanda in the past, which is also because the styles of Perfect World and Shanda and other game companies are more similar. Giants such as Netease, Tencent and even Sohu Changyou started from portals or communication tools, and then gradually tilted their strategic focus to games, while Perfect World and Shanda started from games at the beginning, and games were the top priority of these two companies’ strategies, so when Shanda became crazy by legends in the past, Chen Tianqiao threw out the concept of Shanda Box with great pride, and also acquired the website of Qidian. Chen Tianqiao’s strategic concept was good, but Shanda Box lacked content support and finally suffered a fiasco. So let’s see, this Perfect World is no different from what Shanda did in those years, except that it acquired the starting point of literary websites in those years, while Perfect World acquired websites such as video game buses this time.

The grand box is an eternal joke.

There is always a touch, secret and great!

There is always a feeling, endless!

Yesterday, alumni donated 78 million anonymously.

At the same time, in the name of teacher Yu Xianjue,

Name the donation project as

"Yu Xianjue Life Science Education Fund"

Who is Mr. Yu Xianjue?

Why is the 78 million donation named after him?

With Luo Luo Jia Jia

Find the answer to the story.

Yu Xianjue, Professor of School of Life Sciences, Wuhan University. People from Changsha, Hunan. Graduated from biology department of Wuhan University in 1935. In 1949, he received a doctorate in philosophy from California Institute of Technology. After returning to China, he served as a professor at Wuhan University, director of the Department of Genetics of the Department of Biology, and the first and second directors of the Hubei Genetic Society. Member of China Democratic League. Since 1980, the karyotype of freshwater fish has been studied and achieved results. Editor-in-chief of Genetics, and author of papers such as Studies on Chromosomes of Freshwater Fish in China.

//

In November 1909, Yu Xianjue was born in a peasant family in Changsha County, Hunan Province. My parents make a living by farming and have eight children, and Yu Xianjue ranks third. Because of his poor family, his parents had to adopt one of his brothers to his uncle who was in business. And my brother provided him with a lot of financial assistance for his later schooling. Yu Xianjue grew up in such a typical southern rural family, studied hard, made progress and was strong since childhood, and had a strong love for nature and biology.

In 1931, he was admitted to the Biology Department of National Wuhan University with honors. During his college years, he not only got excellent grades, but also loved sports. When he graduated in 1935, he was recommended by Professor Zhang Yingwu, an embryologist, to stay in school as a teaching assistant in the Department of Biology.

▲ Yu Xianjue graduation photo, a bachelor of Wuhan University in 1935.

Ten years after his graduation, during the period of War of Resistance against Japanese Aggression, he moved to Leshan, Sichuan with Wuhan University. During the hard war years, he not only didn’t lose his major, but also studied hard, worked hard, compiled his own handouts, and enriched his theoretical knowledge in the teaching practice of histology, cytology and embryology. In the second year after the victory of the Anti-Japanese War, Yu Xianjue was funded by the Lee Foundation and was sent to the Biology Department of California Institute of Technology to study for a doctorate. Yu Xianjue entered Morgan’s laboratory at California Institute of Technology and became a student of Professor Sturtevant.

Mendel made a pioneering contribution to establishing the basic principles of genetics. Morgan and his students used Drosophila as materials to discover the laws of sex-linked inheritance, linkage, exchange and non-segregation, and put forward the theory of genes, which is a significant development of Mendel’s theory of genetics and laid the foundation for the development of modern genetics. Professor Yu Xianjue is a modern geneticist who grew up in Morgan’s laboratory during this period.

At that time, Morgan, the founder of the biology department of the school, had just passed away, and Morgan’s eldest disciples, Sturtevant and Mrs. Morgan, continued to study fruit flies in Morgan’s laboratory. Sturtevant received his doctorate from the Drosophila Laboratory in Morgan, Columbia University in 1910, and then came to California Institute of Technology with Morgan. Sturtevant students E. B. Lewis and E. Novitski gave Yu Xianjue direct guidance in experimental research. Lewis later became an academician of the American Academy of Sciences, and won the Nobel Prize in 1995 for his achievements in developmental biology of Drosophila.

Four China scientists of the older generation have studied in this laboratory, namely Li Ruqi, Tan Jiazhen, Lu Huilin and Yu Xianjue. Yu Xianjue completed his research work during his doctoral period in 1949, wrote a 112-page doctoral thesis, successfully passed the doctoral thesis defense, and obtained his doctorate.

▲ Yu Xianjue at California Institute of Technology, USA

Yu Xianjue’s doctoral thesis is to study the reverse mutation and position effect of Drosophila by X- ray technology, and his tutor and Lewis are very satisfied with his experimental results. Yu Xianjue made a series of new discoveries, including the famous antenna foot mutation in modern genetics textbooks. This Drosophila mutant named AntpYu was recommended by Lewis and incorporated into the genetic variations of Drosophila melanogaster, and published by Carnegie Institute in 1968. The discovery of this mutant laid a foundation for Lewis and others to study homeobox genes and the development of Drosophila. Also included in the book is T (2; 3)AntpYu mutation, B48g, Scar, T (2; 3)B48g and t (2; 3) Scar mutation, etc.

Yu Xianjue is very patriotic. After receiving his doctor’s degree, he decided to go back to China and devote himself to the construction of new China. At that time, his brother was the Consul General of the National Government in Houston, and repeatedly advised him to stay in the United States, but Yu Xianjue’s determination to return to China never wavered. The journey to "go home" was hard. He knew that the motherland lacked professional books, and brought back a large number of professional books and documents with him. When he returned to Tianjin to go ashore, it coincided with the establishment of New China on October 1, 1949. After several rounds of rolling, he returned to Wuhan and once again devoted himself to Luojiashan as a professor in the Department of Biology of Wuhan University. Yu Xianjue has taught in the Biology Department of Wuhan University for more than 50 years.

Letter from Hu Shengchu as a Professor of Science College

Yu Xianjue is a loyal Morgan scholar. Since the 1960s, with the acceptance of Morgan School in the whole country, he selected fish as materials for genetic experiments and enrolled graduate students. However, it was soon devastated by another decade, and the newly established genetics laboratory had to be terminated. It was not until the end of the Cultural Revolution in 1978 that he resumed recruiting graduate students and conducting genetic research.

The Chinese Genetic Society was established in 1979, and Professor Yu Xianjue was elected as the first director of the Chinese Genetic Society and the first editorial board of the Journal of Genetics. In the same year, Yu Xianjue advocated the establishment of Hubei Genetic Society, and served as the chairman of the Society for four consecutive years, making great contributions to the development of genetics in Hubei Province. In 1980, he was elected as the first director of China Society of Cell Biology. After the National Science Conference in 1978, he compiled the outline of "Introduction to Genetic Engineering" and made a report to Hubei provincial authorities, Wuhan University and other universities, which played an important role in publicizing Mendel’s genetic theory and popularizing genetic knowledge.

He and graduate students have conducted extensive research on cytogenetics of freshwater fishes in China, and obtained the first-hand information on cytogenetics of freshwater fishes in China, which is the first systematic study on chromosomes of freshwater fishes in China in China. The research achievement "Study on the Karyotype of Freshwater Fish in China" won the second prize of the Science and Technology Progress Award of the State Education Commission in 1988, and was edited by Yu Xianjue and published in Science Press in 1989. This book has become a reference book in the field of fish genetics research.

On the basis of these studies, he further studied the fine structure and genome of fish chromosomes, and the research result "Study on the Fine Structure and Genome Structure of Fish Chromosomes" won the second prize of the Science and Technology Progress Award of the State Education Commission in 1995.

Yu Xianjue’s granddaughter Yu Li said that Grandpa’s students have always been in contact with their families, and this anonymous donation by alumni was also directly contacted with her. She felt very surprised and very moved. "My mother and I have advised before, but the alumni said that this is their long-cherished wish for many years."

Following Yu Xianjue’s footsteps, Yu Li has also been teaching in the College of Life Sciences. She grew up beside her grandfather. At that time, she didn’t know much about her grandfather’s work. She just felt that other people’s grandfathers seemed to have time to play with their grandchildren every day, but her grandfather was very busy all day long. Occasionally, she would take her to make gecko specimens or climb Luojia Mountain to plant small plants when she was free. I didn’t understand until I grew up. Influenced by the Cultural Revolution, Grandpa, as a modern geneticist who grew up in Morgan’s laboratory, had interrupted his academic research countless times, so once he returned to his scientific research post, he devoted himself to his work with double enthusiasm and energy.

In her memory, there were always students coming and going at home, some came to ask grandpa academic questions, some came to report the progress of the experiment, and grandpa was always cheerful and equal and gentle to the students. If he was still talking about work at dinner time, he would ask his mother to serve a bowl of noodles covered with eggs and continue to discuss the problems with the students while entertaining. At that time, a bowl of egg noodles could be said to be quite good food.

▲ In the 1960s, Yu Xianjue was instructing graduate students.

Yu Xianjue was honest and broad-minded all his life. Peace of mind and noble character; Life is simple, honest and simple; Strict scholarship and profound knowledge; Good teaching and tireless teaching. He has successively directed cytology experiments and embryology experiments, and taught courses such as histology, cytology, genetics, zoology, entomology, introduction to biology, agriculture and livestock breeding and cytogenetics.

His teaching preparation is well-prepared, his lecture language is accurate, his concept is clear and his logic is strong. He always said, "If you don’t memorize in advance and think about what to say temporarily, it’s easy to digress and make mistakes." His teaching has been well received by teachers and students in the Department of Biology.

Yu Xianjue attached great importance to discipline construction and personnel training, and established the doctoral program of genetics in Wuhan University, which was also the second batch of doctoral programs in China at that time. Now it is a national key discipline and a comprehensive genetic research institution and personnel training base with complete research directions in plant genetics, animal and human genetics and microbial genetics. Professor Zhu Yingguo, an academician of China Academy of Engineering, and professors Yu Qixing, Song Yunchun, Zhou Gang, He Guangcun, Yang Daichang, Hu Zhongli, Li Lijia and Li Yangsheng all grew up in this doctoral program. In his later years, he enrolled the only postdoctoral fellow, Zhou Rongjia, and later became a professor in the department.

"This alumnus who donated anonymously is my senior. I am also very excited to hear about this charity. He is definitely influenced by Teacher Yu. This is a typical student of Teacher Yu!" Zhou Rongjia said. In 1992, Zhou Rongjia entered Wuhan University to engage in postdoctoral research with Yu Xianjue. At that time, Yu Xianjue, who was over 80 years old, was in poor health, but he still talked with Zhou Rongjia specifically and told him to be a good person before doing scientific research.

"This sentence has a great influence on me," Zhou Rongjia remembers vividly. At that time, the conditions of the postdoctoral mobile station were very difficult, and many studies were almost started from scratch. Yu Xianjue gave Zhou Rongjia great autonomy and allowed him to play freely within the framework of fish genetics. "The old man was very low-key, but he did very well academically. He said that being a man must have a pioneering spirit, which has had a profound impact on my academic path. "
