In the experiment, the filling-body was made of tailings used as the basic material, water as the slurry and 325# Portland cement as the cementing agent.
These materials were mixed in the mixing barrel according to the different ratio requirements, and stirred for 10 minutes at room temperature, then molded into 25mm filling balls.
Conclusions In the experiment, the filling-body was made of Jinshandian's tailings as the basic material and 325# Portland cement as the cementing agent.

To give an idea of the importance of their exports, by 1892 the annual Longleaf cut was estimated at more than 16 million cubic meters and the American Lumberman was crowing that “the timber material par excellence of the whole North is Longleaf yellow pine” [3].

Indoor air also contains hundreds of GP emitted from diverse sources, such as building materials, paints, furnishing, cleaning agents, combustion appliances, and outdoor air pollution [2-4].
Common sorbent materials include activated carbon, activated alumina, silica gels, zeolites, synthetic polymers and clay minerals [3].
This emerging air purification technique involves the use of ozone in combination with zeolites and other related porous materials [11].

MOOC: Challenges and Opportunities of Higher Education ZHE YAO Computer Science, University of Nottingham, UK zheyao.marissa@gmail.com Keywords: MOOC, Higher education, Completion rate Abstract.
In many cases, the video lectures are presented in the form of tablet recording, and the worst approach is to teach learners by showing and reading materials page by page.
Learning Resource Learning resources consist of textbooks and additional materials including web pages, journals and other books relevant to this course.
It should be stressed here that the quantity of additional materials in each lesson is no more than five as too much resources may eventually lead to the lost of enthusiasm.
