Mining machinery industry is an industry that contains technology http://www.cheapestairmaxonline.com/ , capital and labor at the same time. In recent years, with the development of mining machinery industry, market continues to expand and the infrastructure efforts have been strengthened. Therefore, mining machines are facing higher and stricter challenges, which not only include technology and intelligent, but also include energy-saving and environment-protecting.
It is the target of people in the machinery industry to develop crushers that are energy-saving and efficient. Traditional mining machines Cheapest Air Max , such as crushers and sand-stone-making machines can meet the need our requirements for air quality at the present stage. Only through upgrading and innovating technology gradually, can we achieve sustainable development for a long time.
People who study crushers has been doing research about how to finish the crushing process in an energy-saving and efficient way, from theoretical innovation to equipment modification, even to the development of new products, as well as improve the production process. At present, the research of crushing theory Cheap Nike Air Max Online , process and equipment pays attention to find a way to make high-efficient and energy-saving come true, so that new theory can be found to fight against the three well-known theories of crusher.
HANGZHOU, Sept. 20 (Xinhua) -- A top university in eastern China has sparked controversy after adopting a rule to assess the works of students and teachers as academic achievements if they receive a high click-rate in online media.
According to the Zhejiang University rule, works published by major media outlets -- the People's Daily, Guangming Daily and Qiushi Journal, may be recognized as equal to publications in authoritative domestic journals if they are viewed as influential.
Works picked up by major commercial portals such as Sina Cheap Nike Air Max Shoes , Sohu and Netease and major publications at Xinhua News Agency and China Central Television as well as on mobile apps and social media accounts, such as WeChat and Weibo, are also equal to publication in key journals if they result in significant influence.
The document also says that the works should be transmitted by no less than 10 mainstream media outlets and have more than 100,000 page views if it is on WeChat.
"Excellent Internet cultural achievements," including original articles, video and animation works Cheap Air Max Shoes , are among academic requirements for promotion or prizes.
However, the rule, which took effect in early September, has sparked debate over its feasibility and the extent to which it may devalue academic work.
Viewing the move as an exploration of academic evaluation, the university said outstanding online work would be recognized by a committee of experts in June each year.
"Given the trend of media convergence, a number of professional scholars Cheap Nike Air Max , institutions and government departments are more willing to publish their academic works through new media first," said Zhu Wei, a communication researcher at the China University of Political Science and Law.
The academic value and influence of some online works far exceeds those of core journals, Zhu said.
Zhu Haijiu with Zhejiang Gongshang University also supported the move.
"In the era of the Internet, only recognizing publications in journals as academic output, is like only recognizing work done with brushes in the era of the pen Cheap Air Max ," Zhu Haijiu said.
But others had misgivings about the rule.
"There may be some problems with the current promotion and evaluation system, but academic value should not rely on the number of clicks," said Yin Jun, a teacher at Shenzhen University in Guangdong Province.
"Papers have strict evaluation procedures, but it is hard to assess articles published on public media," said a teacher at Zhejiang University.
Zhejiang University is not the only school to explore the evaluation of online work.
Shanghai Jiao Tong University has piloted a rule that excellent Internet works can be a qualification for the promotion of certain officials. Jilin University also adopted a rule encouraging the creation of online work.
In 2013 Cheap Air Foamposite One , the Ministry of Education proposed to formulate a regulation on the absorption of excellent online work when calculating academic results. In 2017, the ministry said it would advance the regulation.
"I am happy to see such an innovative measure, but I hope supervision covers the publication platforms during implementation to ensure fairness," said one web user.
There’s lots of methods to fastening things together. Such methods are riveting, bolting, pinning Cheap Air Max 2 Light , keying, welding, bonding or magnetism. Many electrical and mechanical machines are mainly joined using bolts and nuts. A bolt contains the model of a nail. It possesses a head plus a shaftcollar. Most bolts once fixed around they can be important to hold are fastened by means of a nut that is certainly similar to but stronger than only a ring. The nut is known for a diameter of equal size considering the shaft of the bolt but has smaller rings on its inside that lock resistant to the rings for the bolt.
Shear Bolts can be a kind of bolts commonly used for locations where require a lot of security and much less maintenance. These are produced from stainless, galvanized mild steel or zinc which you’ll find all really hard metals. They may be built to provide a permanent one way of many fixing since once installed they can not be reinstalled. These bolts are fixed using standard spanners by tightening. When fully tightened the hexagonal head was made to the extent that it will break or shear aloof from the main bolt collar or shaft thus offering a permanent fixing.
