Do the metallic atoms penetrate directly in the point of contact or they diffuse a along oxide layer with simultaneous penetration into silicon (like diffusion along grain boundary with simultaneous leakage into bulk in the Fisher-like models [5]).
So, we can just take concentration of nickel atoms (number per unit volume) to be almost zero at silicon side of oxide film and at nickel side.

Originally spouted bed was just suitable to grain drying, and the area of its research and application are steadily extended.
Conventional spouted bed consists of two parts: 1) Cylindrical main body, certain number of fluidized particles with diameter larger than 1mm is loaded in advance; 2) Conical base body, entrance of airflow is in the bottom of it.

However, supposing the manufacturing processes are not carefully controlled, a number of undesirable phases such as carbides, nitrides and intermetallic compounds may precipitate in the microstructure.
It can be seen that in Fig.1 (a) that the σ phase precipitates on the phase boundaries and grows into the surrounding ferrite (α) grains (white: austenite phase, grey: ferrite phase, black: σ phase).

It has been used for pumping water and grinding grains for many centuries.
Truckenbrodt. [6] The velocity distribution on the profile contour at discrete points Xn is obtained through the following summation formula; WkXnU∞=1Xn*an+2m=1N-1AnmZmt±2m=1N-1CnmZms ±αbn +2m=1N-1HnmZmt‘ 2 Coefficients an ,bn , cn , Anm ,Cnm ,Hnm to calculate the velocity distribution on the contour profile according to Eq. 14 for N = 12 are given in [5] (10) where Xn*=Cn+dZtdφn2 And an ,bn , cn, Anm, Cnm and Hnm are Fourier series coefficient, and N is the number of discrete nodes. [5] Flowchart for the Calculation of the Forces and Torque of Wind Car As given in NACA profile we can indetify the geometric parameters of the airfoil.

It makes the land stalinized year after year and output of the grain.
It shows in Fig. 3: Fig. 3 Influence of UASB reactor operation days on turbidity removal From Fig. 3: the wastewater turbidity removal is rising with the increase of the number of days running device.

However, due to the open grain characteristic of porous asphalt mixture, the utilization technology of RAP on recycled porous asphalt mixture has the following features.
The references are to be numbered in the order in which they are cited in the text and are to be listed at the end of the contribution under a heading References, see our example below.

On both sides of the interface is not smooth, there are a number of AlN grains embedded into the Ni layer.

Having a relatively longer service life, the lower mold can be taken larger grid size to reduce the grid number, with minimum mesh size of 3 mm, ratio of 3, 22427 grids and 5120 nodes.
If the heating temperature is exorbitant, coarse grains, excessive heat or burn of aluminum alloy material will appear, causing the deterioration of the forging performance.

*ARI: The long-term average number of years between the occurrences of a flood.
Conclusions As conclusion, it can be conclude that Sembrong River Dam slightly shows high soil loss where is consist of soft fine grained silty clay material with organic matter, tree roots and decaying timber.

In addition, they may have inferior resonant characteristics due to a large number of defects in these SiC films such as stacking faults and dislocations or grain boundaries.
