Impacts of Climate Change on Locust Outbreaks in China＇s History

Global warming is causing the climate to change, lakes to dry up and less rain to fall. In population ecology, researchers have found that climate change plays an important role in controlling the size of species populations. To proof this model long-term observational data are crucial, making researchers to turn to historical records of locust outbreaks.     

CAS scientists active in earthquake relief operation

Soon after the devastating earthquake taking place on last 12 May in Sichuan, the CAS leadership promptly mobilized its researchers to dedicate their expertise to the nationwide drive of the disaster＇s relief and reduction. A leading group was established to coordinate the Academy＇s efforts in this regard. All of the eight CAS institutions located in Sichuan were organized to do everything possible to reduce their losses to the minimum. At the same time, a trans-departmental and interdisciplinary taskforce was formed to provide a powerful S＆T backing for the nationwide drive.     

DESIGN OF INTERNETWORK MANAGEMENT BASED ON VLANs

Implement VLANs essentially creating smaller broadcast domains at layer 2, means that broadcasts sent out from a node in one VLAN won t be forwarded to ports configured to belong to a different VLAN. In this paper, we assigning users to VLAN groups on a switch, this help to gain the flexibility to add only the users you want into that broadcast domain regardless of their physical location. This setup can also work to block broadcast storms caused by a faulty network interface card （NIC） as well as prevent an intermediate device from propagating broadcast storms throughout the entire internetwork.

To what extent is language teaching methodology informed by theory？

With the globalization of the world, language teaching becomes more important than ever before, and many universities and classroom teachers are active to exploret he most efficient and effective methodology to teach languages to achieve a desirable result. When they seek to improve the quality of language teaching, they often research teaching methodologies by referring to general theories about language and language learning. Theoretical bases and teachers‘ hands-out experience have informed methodologies of language teaching, and methods of language teaching have been improved with the developments about linguistics, psychology and education. But there is a question which extent the information that theory has made available can be used to explore language teaching methodology and of the relevance of theory to language teaching methodology.     

The Need for More Women Scientists and Young Scientists To Be Engaged in Chemistry- A Central Science

This year, 2011 is a very important and meaningful year for chemists.The United Nations has declared 2011 as the International Year of Chemistry (IYC 2011), which is the year for the worldwide celebration of the achievements of Chemistry and its contributions to the well-being of mankind.The goals of IYC 2011 are to increase the public appreciation of chemistry in meeting world needs, to encourage interest in chemistry amongst young people, and to generate enthusiasm for the creative future of chemistry.The year 2011 also coincides with the 100th anniversary of the International Women's Day on March 8 as well as the 100th anniversary of the Nobel Prize awarded to Madame Marie Curie -a great opportunity to celebrate and to highlight the contributions and achievements of women in science.
