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.

Study of FIDIC Condition in innovative Engineering Environment Zhaohui Liu Hubei University of Science and Technology 1711784450@qq.com Keywords: The FIDIC Condition, Application, Measure Abstract The FIDIC Condition has been widely applied in the international engineering.
Due to the buyer's market, the contractor, material equipment suppliers, supervision unit to turn around the owner, exists the phenomenon of insufficient supervision fees, crude equipment configuration [2].
The Owner's Behavior Because of buyer's market present, the owner often forced the contractor, material suppliers, Supervision Company to sign unequal clause.
It will be bound to cause the contractor, material suppliers jerry-build, carpetbag behavior.

Yuan Jin [1] pointed that pile pH values could be through the following ways: adjustment of raw material control C/N to change the ammonia production capacity and loss amount, ensure the proper pH value; making the aging sludge organic fertilizer backflow to prevent local anaerobic and excessive organic acid production, and adding auxiliary to make the pores increases, easy to oxygen, prevent the organic acid and partial anaerobic produce, and to prevent the decrease of pH value.
Design of experiment Test materials.
Sludge degradation of polycyclic aromatic hydrocarbons by materials the influence of pH value, pH value in the environment can influence the microbial enzyme reaction speed.
