The shredding represents the unitary operation to reduce the geometric dimensions of food materials due to external mechanical action [16, 17].
Shredding of food material must be capable to maintaining the material properties, in the cutting process must not appear excessive heating or possibly of breaking the material due to inadequate choice of cutting device [11, 12, 20].
Experimental procedure To achieve the laboratory experiments, for better relevance of experimental results from the variety of food materials were selected to study a variety of materials textures with different properties and homogeneity so that it covered a wide range of properties of food materials with soft texture (Table 1).

Introduction In our life, there is noise everywhere and the noise pollution has become one of the three pollution in the world, which not only affects the people's health and the people's normal work and rest, but also is the main root of reduce worker's efficiency and causes of all kinds of accidents, therefore the noise must be controlled.
is the sound propagation speed of the first layer absorption material. . is the elastic modulus of the first layer sound absorption material. is the density of the first layer sound absorption material. is the structure loss factor of the first layer sound absorption material. is the transmission wave number of the first layer sound absorption material, .

According to Kurt et, al., packing pressure and mold temperature among the most influential factors when it comes to optimizing shrinkage and roundness [3].
On the other hand, changing the holding pressure does not affect the dimensional stability by a huge margin.
This result contradicts with the known theory, and it might be affected by the material’s maximum shrinkage limit.

This study combined microscratch test and fracture-mechanical analysis to assess the interfacial reliability of Nafion and Pt/Ru catalyst layers in micro fuel cells.
Scratch test was used to determine the critical load for interfacial failure, while fracture-mechanical analysis was used to quantify the adhesion between Nafion (the electrolyte polymer substrate) and Pt/Ru alloy (catalyst coating).
In particular, the performance and lifetime of cells are directly affected by PEM delamination phenomena during operation, since mechanical reliability plays an important role in the chemical interaction between packaged laminates [2].
The value ∂Fn/∂C is an increasing rate of the normal force required to extend a crack and is an important factor in arriving at a quantitative adhesion parameter [9].
Note that the value of ∂Fn/∂C does not take into account the material properties of the coating and substrate and thus is merely a qualitative and relative value that is meaningful only in comparing the materials of the same kind.

While electrical conductivity is being introduced, the impact of these conducting polymer and filler on hydrogels’ properties can be very different.
The results indicating the mechanical properties of conducting hydrogels were enhanced by the incorporation of PANI into PAA hydrogel matrix.
However, graphene was shown to be able to improve the biocompatibility of PAA hydrogel[16], hence adding of graphene filler with proper dispersion and amount is crucial to obtain hydrogels with good conductivity and mechanical properties.

In the context of mixing process, two different fluids and have a different properties will mix in a single equipment to produce another fluid with a new property.
In order to investigate the kinds of flow properties, a Particle Image Velocimetry (PIV) technique with 1 µm seeding particle was used.
Most of the mixing operations are performed by mechanical stirred tank.
During their study, they found that the spacing between impellers significantly affected the flow pattern.
Research on the space filling fractal were carried out by Hurst & Vassilicos [14] who found that the static pressure drop for the space filling fractals is independent of the thickness factor; moreover, away from the grids the homogeneity is improved as a function of the thickness factor.

He uses a solid model to reveal the dynamic property and damage forms of a CFST through arch bridge under the impact of an earthquake.
Besides, they also study how the elastic restraint of the bridge deck system affects the dynamic performance of the main arch.
They conclude that the most significant influencing factor is rise-span ratio.
This process turns a complex real model into a simplified spatial mechanical model which can be used in mechanical analysis [5].
Therefore, in the simplifying process, it is the major factors that should be focused on rather than those less important ones.

Based on their major decisive roles as the controller, supervisor, supporter and assistance for the project, the implementation of the project may be greatly affected if the relations with them haven’t been handled appropriately [2].
For the subcontractors, there should be arrangements for the workforce and materials, the temporary facilities planning, the organization for the entrance of mechanical equipments and the reconfirmation for the material source and financial circulation.
While based on the diversification of the influencing factors, there are no universal-applicable rules.
The Methods of Organizational Coordination The organization and cooperation is a complicated work that covers a wide range and be greatly influenced by subjective and objective factors.
