In the cloud computing security model, authority management and identity authentication is must done, being conducted to ensure that only people who have relevant permissions to access the Hadoop data; network threat defense is setted up, which realizes intrusion protection; Data encryption is done to prevent data theft; Ensuring the integrity of the data ensures the data will not be tampered with; virtual technology is used to realize dynamic management of material resources and protect the safety of cloud environment., cloud computing security policy model based on the structure of the Hadoop can be obtained on the above of protection strategy.

Tourism is not to sell material objects, so it needs to rely on advertising.
From its characteristics, tourism gets natural advantages to develop e-commerce; first, its intangibility and non-transitivity decide it seldom involves material object transportation; tourist activity causes “people flow” instead of “objects flow”; application of e-commerce on tourism are with low requirements on material object distribution.

The most dramatic for the coal industry future events occurred in 1998, when all raw material industries of Russia felt victim to the global financial and economic crisis.
In the national economic science, there are different views on the connection between these crises and problems in the economy of Russia.
Diversity of views on this issue is clearly traced from 2009, starting with the first scientific publications in such prestigious scientific journals as "Problems of Economics".
In both cases, most of the economic indicators of the coal industry of the Russian Federation showed negative dynamics The main reason for decline in coal mining had been a sharp fall in world prices for many types of Russian export raw materials.

Brazing of AZ31B Magnesium Alloy Sheet Takehiko Watanabe1,a and Kengo Oohara1 1 Graduate School of Science and Technology, Niigata University Ikarashi 2-nocho, Niigata, Japan a email: twatanab@eng.niigata-u.ac.jp Keywords: Brazing, Mg alloy sheet, Flux, Filler metal, Surface preparation, Cross tensile strength Abstract.
Introduction Magnesium and its alloys have been widely used in various fields because they are the lightest metal in the structural materials and possess many excellent properties such as high specific strength, low density, good and economic processability by using cast technology, and high recycling potential.
The material used in this study is a rolled magnesium alloy plate AZ31B-H24 0.9 mm thick (hereafter, called the Mg alloy) with a main chemical composition of 2.8 mass% Al and 0.9 mass% Zn.
