Das and co-workers fabricated two series of flexible PU foams by substituting petroleum-based polyol with increasing amount of soy-based polyol (SBP) having different hydroxyl numbers and their results showed that the morphology and mechanical properties of the foams were affected significantly by the foam fabrication method and SBP hydroxyl numbers [5].

High densities generally result in improved load-bearing properties [9].The support factor or SAG factor or compressive deflection coefficient is the ratio of 65% indentation force deflection (IFD) to the 25% IFD.
This factor can be used to indicate the cushioning quality; higher support factors indicate better cushioning quality [9].
Nevertheless, the support factors of all foams containing palm oil-based polyol were higher than that of reference foam indicating better cushioning quality.

Diamond-Si nanostructured composites were obtained by cyclic high pressure and high temperature sintering with different processing conditions to examine the dominant microstructural factors and the abrasive wear resistance.
Recent studies [9] have shown that nanostructured diamond-SiC composites exhibit an even superior improvement in mechanical properties, especially the toughness.

Indeed, the chip formation is due to a combination of two thermomechanical factors.
This factor depends both on the interface adhesion properties and on the substrate/coating thermal expansion coefficients.
This factor is enhanced in polyamide coatings having a low mechanical strength and a high thermal resistivity.
Taking into account these conclusions, the substrate thermal properties must have an influence on the coating removal efficiency.
The comparative study of different substrate highlighted the influence of the substrate thermal properties.

It is influenced by several factors [1]: process variation during the production line (e.g mask misalignment); environmental – variation during circuit operation (e.g temperature fluctuations); systematic variation as metal dishing or lithography proximity effect; random variation, as material variation; design related issues etc.
In addition, the algorithm can be applied on any parametric response, as layer thickness, other layer properties, defect count, etc.

Calculated on the influence of strata movement, there is a empirical formula for the coal’s alternate distance.It is necessary to analyze the factors in the formula Introduction Close distance coal seam mining in working face of the reasonable distance determination is often encountered in coal mining, which directly affects the upper and lower two layers of the work of the safe production and production organization, reasonable determination of upper and lower working face fault distance can avoid two coal face each other at the same time because of adverse effects caused by mining.
can be used to calculate the coal’s alternate distance Organization of the Text The empirical formula to calculate the coal’s alternate distance Calculated on the influence of strata movement, there is a formula for the coal’s alternate distance in experience: Fig.1 The model of the minimum offset under the influence of strata movement H—the space of coal seam; L—Considering the stability of the roof strata in the upper face and the safety distance of the upper and lower face caused by the unbalanced recommended speed, generally not below) 20 ~ 25 m; δ—Angle of rock movement,the hard rock is 60 ° ~ 70 °, the weak rock is 45 ° ~ 55 ° b—The biggest accused of zenith distance of the working face in the upper coal seam Using this method to mine the close distance coal seam, it is important to note tha t the offset of the up and down coal mining face must not be too small, so as to avoid the powered impact on the floor of coal because of the seam roof caving and the affect
The rock layer’s trend subsidence angle δ is not only depended by rock properties but also by the mining methods, mining thickness, mining depth, goaf area, and others factors.
And get the empirical formula: (1) In the formula: a, b are the physical and mechanical property of rock.
So based on the mining depth, mining thickness, and rock’s physical and mechanical properties, we can adjust the size of mining face displacement according to adjust the rock movement angle. ③The impact of safe distance L on the coal’s alternate distance Actually, In formula (1) the main factors influencing the concurrent slicing distance is the value of L, L is distance of the upper face roof stability and upper and lower face advancing speed unbalanced considering the safe, the value of L mainly depends on periodic weighting step distance, When the working face advancing to a certain distance, basic roof cantilever under the action of gravity and the overburden, and will produce fracture caving, at this time also will bring face pressure phenomenon.
