However, Study abroad saline soil microorganisms have always focused upon salinity microorganisms isolated and ecological characteristics of saline extremophiles and gradient changes in physical and chemical properties impact on the number and structure of microbial and other aspects.
Hetao irrigation area is an important grain-producing areas, but 23.3% of the total region's land area affected by salinity hazard , severely restricting food production[12-13].
The higher the degree of soil salt damage, the fewer the number of microorganisms.

A number of approaches for generating electroluminescence from ZnS quantum dots have been reported, including device structures that compose of organic, inorganic and hybrid materials to form charge transport and injection layers [12].
These results conformance according to card number [ICDD PDF 65-1691] which are in a good agreement with the results of the prepared ZnS QDs.
The prepared ZnS QDs has a small average grains size from XRD of 3.82 nm.

Ksp = MaAb = aMc+ + bAc– (2) where a and b represent the numbers of cations and anions, and c+ and c– are the valencies.
In addition to this, the struvite precipitation potential for ammonium nitrogen removal could be enhanced by using quartz grain as the seeding material [45–47].
When a large number of K+ was present in solution, it could compete with NH4+ forming MgNH4PO4 analogs (MgKPO4), reducing the content of Mg2+ and PO43– available for the formation of struvite [50].

A large number of papers deal with Tool Condition Monitoring (TCM).
These bars have the same heat treatments as the discs (solution Heat Treatment and aged) in order to obtain the nearest routine mechanical properties to the original discs (same microstructure, same grain size ≥ 8 (ASTM) and same Hardness HV ≥ 410 HV30).
Acknowledgments The research leading to these results has received funding from the European Community's Seventh framework Programme (FP7/2007-2011) under grant agreement number 213855.

It is important to control Cadmium (Cd) content in rice and ensure the grain security.
The number of rice plant samples was more than 5, at the same time the planting density was recorded.

Rice husk is generated as a waste during the first stage of rice milling, when rough rice or paddy rice is husked (husk is separated from the rest of the grain),it contains about 20% silica in combination with a large amount of the structural polymer [8].
This might be due to the increase in the number of prose on the biomass surface at high temperature.
According to Langmuir isotherm, the biosorbent surface occurred as monolayer biosorption on the homogeneous number of exchanging sites.

The corrosion resistance of stainless steel is defined not only by the steel grade (composition of chemical elements, grain size, surface structure, ...) but also by environmental conditions (gaseous or liquid substances) [1, 2, 3].
In a second, following step, the surface of these specimens were anodically charged with a number of 5.3x10 6 pulses.
Using CV-scans (as done here with a number of five) can reverse the foregoing effect of enlarging of chromium activity back to the level of the untreated condition.

Aggregates: a) Sand: river sand with fineness modulus of 2.60, II zone gradation; b) Stone: gravel with grain size of 5~15mm, crushed index of 6.6%, gradation qualified.
Six groups of mix ratio (Table 4) in line with the different construction requirements were designed to be the mix ratio for the non-dispersible underwater concrete on the basis of a large number of experiments.
UWB-II polysaccharide type of AWA developed by using the polymer glycerol polymerization technique has long chain structures of macromolecular compound, which were absorbed on the cement particles in the dispersion system through a number of active functional groups on the long chain.

Since 1990, there are growing number of literatures conducted on estimating the values of various ecosystem services.
The major factor that stimulates the development of Xi’an is urbanization process, and this process can be divided into five stages: 1) 1949-1957, Xi’an was nominated as one of the key areas for industrial development (mainly heavy industry) in China; 2) 1958-1965, Xi’an was treated as one of the “strategic backbones” - for the reason of national security, a large number of research institutes and universities has moved to this city; 3) 1966-1976, as a result of the “third front construction” policy Led by the government of People's Republic of Chian, large amount of infrastructure construction of national defense, science and technology, heavy industry and transportation has initiated in 13 provinces of Western China since 1964 with the guiding ideology of combat readiness
To estimate the ecological service value of research area more precisely, we calculated the economic value of average natural food production of cropland per hectare per year with the data collected from local statistical resources, and national average price of these grain types with data collected from the China Rural Statistical Yearbook in 2011.

In addition to the severe contact between tool and work material, The vibration is mainly produced by the variations of the components of the cutting forces due to adhesions and transfers of micro-grains of materials leading to a sensitive geometric variation of cutting edge.
This generated a large number of features to acquire maximum information about tool state.
The number of decomposition levels (nls) depends on the sampling frequency of the analyzed signal (fs) in order to allow the high level signals (approximation and detail) to cover the whole range of frequencies along which the wear-sensitive frequency changes during the different phases of wear of the cutting tool.
