Introduction At present engineering dewatering has been widely used to improve soil physical, mechanical properties.
Water-holding density after pumping could easily be determined based on above equation, which is not affected by test sampling depth, soil samples package and other factors.
Considering saturated density not belongs to soil basic physical and mechanical indexes, thereby it can’t be directly obtained through test, therefore based on initial natural density, specific gravity and water content provided by “engineering geology report”, saturated density can be derived from through series of formulas calculation.
When using process specific field instead of final specific field, the calculation accuracy requirement as well as increased costs and other factors extending pumping time demand should be considered.

However, it was demonstrated that more than 6500 genes are involved in bone healing: this outlines that multiple biological factors are needed to promote the formation of the complex molecular environment for the optimal formation of bone [5].
Yet, pore size, volume fraction and shape affect the mechanical properties of the material, which significantly influences the osteointegration between implants and surrounding tissues [17].
Until now, before the advent of the CAD-CAM customization of the bone plate that allows splitting the biochemical composition properties from the biomechanical issues, it was a difficult compromise to obtain a bone-like porosity and a sufficient mechanical strength; if mechanical integrity was reduced, this might result in a implant failure.
Hydrophilic and osteoinductive properties have also been improved using HA coating of total surface area to favor a better biological fluids ad cell infiltration and colonization as well as osteogenic differentiation. 2.
The novel mineralization process procedure overcomes two limitations: maintaining the collagen structure and functionality intact and not affecting the HA morphology and cristallinity.

The mismatch between steel substrate and composite coating is still the dominant factor for the residual stresses.
Residual thermal stresses significantly affect the mechanical performance of the material and they are responsible for initiation and expansion of cracks and even the possible failure of whole material [3].
Material properties of each coating layer were calculated considering the gradually-changing composition of Fe3Al and Al2O3 [5], starting from pure Fe3Al layer (C1) to pure Al2O3 layer (C5).
Material properties of substrate and coating layers are listed in Table 1.

Nevertheless, PM parts are limited in terms of the shape complexity and production efficiency, not to mention the poor mechanical properties and corrosion resistance caused by large porosity and density gradients.
This process allows the production of more uniform microstructures and improvement of mechanical properties.
While, for sintered 316L SS, mechanical properties and microstructure were the major of concerns.
Castro et al compared the corrosion properties of 316L SS produced by MIM, wrought and conventional [8].
Muterlle et al [9] investigated the mechanical properties and corrosion resistance of MIM 316L SS containing delta ferrite.

Introduction Due to the excellent thermo-mechanical properties, such as high strength, low irradiation swelling, low thermal expansion coefficient, and high thermal conductivity, Ferritic/martensitic (F/M) steels are generally considered as candidate structural materials for fourth-generation reactors and fusion reactors.
The presence of helium bubbles can affect the mechanical properties of materials, such as low-temperature irradiation embrittlement and non-hardening embrittlement at high temperatures.
Experimental results showed that high density of helium bubble can induced hardening to F/M steels [16], while the effect of He (size & pressure) on mechanical properties is still unsolved [17].

It is difficult to directly quantify the various indicators, which makes the estimate a great variety of subjective bias, and then affects the feasibility of decision-making results.
Based on in-depth analysis of practical problems, the related factors are decomposed of several top down levels in accordance with different properties.
Factors of the same level belong to those of the upper layer or influence the upper layer factors, at the same time, dominate the factors of the lower layer or be influenced by the lower layer factors, while factors of the same level are independent from each other as much as possible.
Whether the interval number comparison matrix meets the consistency of the results directly affects the sort of rationality.
Managers should pay more attention to the above factors.

Porous wide bandgap semiconductors have been widely studied in the last decade due to their unique properties compared to the bulk crystals.
GaN received attention from the researchers as an ideal material to fabricate chemical sensing devices due to its excellent properties such as high thermal, mechanical and chemical stabilities, large band gap and high breakdown voltage.
The structural properties was characterized using Scanning Electron Microscope (SEM).
For metal contacts to GaN, the condition of the surface is a key factor in determining the electrical properties.
High quality of Schottky contacts have been key factors in improving performance and reliability.

Dynamic recovery does not occur at the early stage of deformation including the yield-point and the subsequent yield drop regime, but it is activated at a large deformation stage, where it is affected by both strain rate and strain.
Introduction Many high temperature mechanical tests of β titanium alloys show a common feature where the stress-strain curves exhibit a sharp initial peak stress followed by a constant flow stress or flow softening.

Gutfinger et al.P[7]P studied the problem of solidification of polymer melts with variable physical properties for non-Newtonian flow between two plates, held at a constant temperature, by means of a combination of a finite element method coupled with conventional numerical methods.
The influences of these factors on the phase changes and heat transfer in the die are analyzed.
Table 1 lists the properties of the materials used.
Figure 12 illustrates that the inlet temperature of the polymer greatly affects its phase change.
The boundary conditions of heat transfer all affect the temperature of the die and the phase change of the polymer.

Experimental procedure and objects of research Specially designed test structures were used for the measurements of electrical properties of polysilicon layers (Fig.1).
Let us discuss how the magnetic field affects the conductivity of disordered systems.
Depending on the average grain size, the doping level and some other factors, different mechanisms of the charge carrier transport become dominant (from over-barrier mechanism to percolation of electrons via the states of grain boundary traps).
