Fly ash is a heterogeneous material composed of a large number of particles of different physical, mineralogical and chemical properties [3].
Fuel and fly ash flow stratify by grain mass to various heights, where these particles constantly swirl around their equilibrium positions.
Grain size, granulometry, particle surface and porosity affect another important property – pozzolan characteristics.

In addition, ETc were used to determine effective rainfall (Er) and to generate hypothetical irrigation schedules to estimate the seasonal or monthly evapotranspiration of applied water (ETaw), where ETaw was an estimate of the ETc minus water supplied by Er [5,6].A great number of studies showed that this method was perfect and developed ETc and widely applied in the most countries [7,8].In China, XU [9]calculating irrigation quota of alfalfa by FAO P-M equation and crop coefficients was studied with the meteorological and the alfalfa experiment data, and estimated irrigation quota under different hydrologic years of alfalfa under different irrigation techniques in Beijing.
The southern Kerqin sandy land was an important production base of commodity grain of Liaoning Province and Inner Mongolia.
Fuxin and Chaoyang located in the southern Kerqin sandy land were the very typical northeast semi-arid region, and also were vital production bases of commodity grain and worsening of the water shortage problems in Liaoning Province in China.As the local major drought-resistant crops and appropriate water-saving crop, more and more corn (Zea mays L.) were produced and their tillage area increasing year on year.

In Figure (2, 3) and (2, 4) dense, homogeneous and nano grain TiO2/ZnO nanocomposite with molar ratio 1:1 could be observed.
Figure (2, 4) show SEM image of surface morphology magnified 500nm the prepared nano grain with several sizes in the range of nano materials could be observed. 3.4 XRD phase structure analyses.
In this test the amounts of colonies are steady and after one hour the number of the bacteria colonies decreases and it takes some time for reactive species reach to the faraway bacteria.

The current was found to increase grain refinement and hardness in the weld nugget zone for the magnesium joints and an increase in grain size and heat affected zone in the aluminum joints.
This can be due to a number of differences between the materials; however, the decrease in temperature suggests that this tool has a lower friction coefficient than steel.

Their production technology has a number of disadvantages [2]: the poor billets quality, smelted in open steelmaking units; increased steel mechanical properties anisotropy by hot plastic deformation, particularly by increasing the forging degree; removing the high-quality surface layer with machining; the deficit press-forging equipment use; large margins stamps preforms (from 30mm - on small stamps, 100...200 mm - at large).
Grain matches 7-8.
After the samples destruction by fractures visual studying (Fig. 8) it have been found (along with the fine-grained portions) characteristic coarse crystalline zone.

No precipitated nitrides appear in grain boundaries when sintering in 75%H2-25%N2 atmosphere, and only the typical porosity is found.

The deformation characteristics are affected by a number of factors, including the alloy composition [6], the heat treatment processes [7], the deforming temperature [8], and the stress–strain cycle [9].
The absence of elongated grain in the as-received material indicates that annealing treatment has been conducted on the material.

The DLC films contain significant fractions of sp 3 type carbon bonds, and their properties are strongly influenced by the ratio of the number of sp 3 to the number of sp 2 hybridized carbon atoms.
However, since the in-plane grain size La of the graphite is always less than 1 nm for the DLC, they follow the relationship ID/IG ¶ La2 [9], instead of the Tuinstra-Koenig relationship [10], in which ID/IG ¶ 1/La.

The formulation number 4 was selected, because it has lower viscosity facilitated the extrusion of the mixture.
All the technical tests were performed on formulation number 4 exclusively. 4 different temperatures of the extruder were tested: 270 ºC, 275ºC, 280 ºC and 290º.
