Therefore, the crystal structure is not a crucial factor to select the catalytic material for a counter electrode in DSCs.
High efficiency of the former is attributed to high short circuit photocurrent density, open circuit voltage as well as fill factor.
This may further explain that the crystal structure is not a crucial factor to select the catalytic material for a counter electrode in DSCs.
Moreover, the Jsc and the Voc are also evidently affected by the characteristics of catalytic material.

It was originally assumed that the calibration curves are not dependent on the properties of the specimen being compressed, however, Sofuoglu [8] performed elastic-plastic FEM simulations that found that the strain rate sensitivity and bulging ratio is affected by the applied friction factor.
To implement the materials plastic properties into the finite element model, the friction correction curve according to the expression below was presented: σMPa=546·ε0.16; The constant (c) = 546 being the strength coefficient and the strain exponent (n) = 0.16.

A shear friction model was taken for a range of friction factors, ‘m’, from 0.1 to 1.0.
The friction factors (m), top and bottom velocities are included in Table 3.

In recent years, with the amount of soil erosion increasing year by year, soil and water erosion has become the key factors affecting the regional ecological security and the ecological environment problems to be solved [4].
There are few scholars to study only on the compressibility of soil, more reflect the compactness using compressibility index, for research and study on the influence of the compactness on the mechanical properties of soil.Song Weifeng et al [5] studied the frictional characteristic between root system and soil; they found that the friction coefficient on root-soil interface increased with increase of density of soil.

The energy transfer rate of the mill has been demonstrated to be a fundamental parameter in the determination of the milling products and their properties.

But the traffic is constant changing, the cars are more and more, overrun, speeding and highly channelizing, together with the difference of the highway original condition of the nation, the difference strength of the roadbed, pavement damage in the earlier period is not controlled effectively under the mutual effects of the various influence factors [3-6].

The BHA model permits prediction of wellbore curvature based on both BHA mechanical behavior and geological influences.
Procedures of the Finite Element Analysis The implementation of the above geometrically nonlinear finite element formulation for the analysis of BHA Model problems consists of the following main steps: Model Property: A steel material will be used with mass density = 7800 kg/m3; Young’s modulus = 209×109; Poisson’s ratio = 0.3.
In contact property option the tangential/normal contact behavior with friction formula (penalty/frictionless) was chosen (friction coefficient = 0.2).

AAS has many advantages such as good mechanical properties, acid and alkali resistance, sulfate corrosion resistance, freeze-thaw resistance, low hydration heat and porosity [4].
With the optimum amount of rubber, the negative effect of rubber on mechanical properties was balanced by the alkalinity effect.
However, when excessive rubber was added, over 5% as found in this study, the alkalinity effect is insufficient in balancing the negative effect of low strength of rubber on the mechanical properties of AASM.
So that, both C-S-H gel characteristics and pore size distribution of AAS are the critical factors to generate higher shrinkage.

Physical degradation is caused by mechanical impacts that change material properties (humidity, temperature, etc.).
The moisture degradation factor based on low velocity of air flow and temperature is not mostly apparent within short time.
