In fact, the structure of casein gel network that forms on renneting, together with moisture removal on syneresis, determines the physical properties of cheese [7].
However, little information could be available on the textural properties of rennet gels produced by reconstituted milk powder, which were more associated with the technical properties of subsequent processing and the consumer acceptability of the final products.
The objective of this research was to investigate the effect of milk composition proportioning on the textural properties of rennet gels produced by reconstituted milk powder.
Conclusions There were different texture properties of rennet gels produced by reconstituted milk powder with milk composition proportioning.
Improvement the texture of reduced-fat gels will require an understanding of the chemical, structural and mechanical properties which dictate these texture attributes.

Crystallographic orientation effect Crystallographic orientation is one of the most important parameter affecting the oxide growth rate and oxide adherence [5, 14-16].
Crystallographic orientation affecting a (Ni,Pd)Al coating, oxidized at 950°C for about 200h.
Chemical pollution Chemical pollution is an important factor influencing the oxidation kinetics and the TGO adherence to the substrate.
This observation shows once again the influence of impurities affecting the oxide growth mechanism.
Oxide growth can proceeds by anionic or cationic mechanisms, depending on the alloy or coating composition which modify the nature and quantity of impurities in alumina, - Chemical pollution may act to modify oxidation and diffusion mechanism, affect oxide growth kinetics and oxide / alloy interface mechanical properties

It can solve some holes with complex plane boundary curves, but it also neglected the around meshes properties of the holes during the process, and hole filling results is not very satisfactory.
For non-closed triangular mesh model, model boundary and hole boundary are both constituted of boundary edges, and the composition of the two boundary properties are the same.
Badly Oriented Meshes Deletion A badly oriented triangle facet which has two boundary edges in its three edges are as shown in Fig. 3, and one can notice that a triangle defined by two boundary edges can rotate around its interior edge without affecting the other triangles.

Introduction Anisotropic material property is required for drawing sheets.
Texture analysis of the hot rolled drawing sheets In some technological conditions, hot rolled sheets product the strong original textures to change its next process orientations and indirectly affect their final mechanical properties.
Seen in the φ1=0 º ODF sections (Fig.1a, 1b), the most unfavourable textures are {112}<110> and {223}<110>, their density levels are great than 5, severely affect sheet's drawability.
The blank size is φ120mm×3mm and its friction factor is 0.2.
Adjusting hot rolled process to reduce the unfavourable anisotropic property will be available to improve the sheet's drawability.

In the absence of accurate method of calculation, increasing the safety factor blindly will lead to large structure size and increasing weight, and increasing strength is not significant, at the same time it will add the cost.
The processing methods of working load affecting the drum are as follows: introducing the conveyor belt when modeling, making a contact process between the conveyor belt and the drum in the analysis, then imposing the circumferential constraints at the drive torque side of the drum and the uniformly distributed loads at the tight side and the loose side of the conveyor belt.
Finite element analysis of drum Solid modeling and material properties defining.
Components of drive drum have many kinds of materials; corresponding material properties are shown in Table 2.

Another application field is the tuning of the properties of 3C-SiC grown on Si as well as the interface of the large mismatched heterostructure [3-7].
Furthermore, it was discovered that Ge incorporation affects, despite its non-doping behavior, the electric properties of the grown SiC layers [9].
The mechanism is not fully understood, but evidence indicates that Ge may affect the concentration of other defects influencing the electric properties of the SiC [10, 11].
Experimental As substrates chemical mechanical polished Si-face 4H-SiC(0001) substrates were used.
This indicates that kinetic factors are dominating the Ge incorporation in the chosen temperature range.

It is our primary interest to develop environmentally safe additives, such as natural plant-based and starch-based additives, for the high concentration CWS with minimal viscosity, nonsettling, and free-flowing properties.[4] The starch widely found in nature, is a rich natural resource, particularly in China.
In a three-necked flask equipped with mechanical stirrer, reflux condenser and thermometer, the appropriate amounts of distilled water and starch were added, gently stirred, heated to 90 °C, then kept at the temperature for 30 min.
The thermal properties were examined by thermogravimetric analysis (TGA), which was carried out by TGA Q500 thermogravimetric analysis instrument (TA Instrument Corp., USA) under nitrogen atmosphere at a scan rate of 20 °C /min.
Zeta potential indicates coal interparticle electrostatic repulsion, and thereby, directly affecting the apparent viscosity of CWS.
The dispersant makes the slurry pseudo-plastic fluid with a shear thinning property meeting the needs in practical application.

This results in a rapid and repeated heating and cooling with consequent unique microstructural, texture and mechanical properties.
The scan strategy is shown to be an effective factor on such a diversity [16], [17].

The review will also focus on the current researches on the degradation of water organic pollutants by using bentonite/TiO2 composite photocatalyst and its key influencing factors.
In the process of preparation of TiO2, calcination temperature affects the crystal of TiO2[51, 52], and further affects the photocatalytic efficiency of the material.
At the same time, various characterization techniques have been used to examine structure properties of bentonite/TiO2 composite.
BET is a common and important method to characterize the specific surface area of materials, which impacts the adsorption properties of adsorbents directly.
In recent years, the high adsorption properties of bentonite has gradually attracted people's attention in the field of environmental purification[58].
