The findings indicate that while both factors affected air permeability, only the changing thickness had a statistically significant impact on the thermal conductivity coefficient.
Table 1 provides sample codes and their properties.
The factors are statistically significant if the p-values are less than 0,05 [9].
Factors and levels.
As can be seen, the p-values of both factors and the 2-way interaction of these two factors are 0.000.

Multi Blade Sawing Process
Hieres Vettorazzi da Silvaa, Nuria F.
Petrographic Characteristics that Affect Mechanical Strength.
Being quartz easily deformable and, at the same time, very important for mechanical properties of rocks, this type of microstructure may affect their behavior in the sawing process.
An extensive literature review about petrographic properties as intercrystalline textures, mineral fabric and descriptive and discursive papers on characterization tests and mechanical properties of stones was also analyzed in order to promote better understanding of the parameters involved in the sawing of commercial granites in conventional multi-blade gang saws.
Kibici: Relations between some quantitative petrographic characteristics and mechanical strength properties of granitic building stones.

Absorption and wet strength are main factors which can effects on the property of impregnated paper.
Its main properties are good absorption, certain wet tensile strength, uniform fiber net, and there is no hard block and hole on a surface.
One of the important factors causing white spot was that impregnated paper didn’t absorb enough resin.
However, their properties are different from the ones on the bamboo plywood formwork.

Mineral Component and Engineering Properties
Mineral component.
Strength and deformation characteristics of the filling are important factor affecting the stability of highway roadbed, and they are also significant parameters in highway design.
These are possible factors to affect rock strength.
There are two factors contributing to this result.
On the other hand, softening and wet-chemical properties of mineral component are the internal factors causing the deformation.

Tension and torsion tests quantified the changes in mechanical properties due to aging.
Factors reported to influence delamination include: elevated temperature aging, residual stresses, texture, and interlamellar spacing [14].
Two processing paths were employed to understand the processing history effects on the drawn wire mechanical properties.
As-drawn wire mechanical properties and microstructures were reported previously [7].
Mechanical property changes with heat treatment temperature revealed the effect of low temperature surface treatment on wire properties compared to hotdip galvanizing.

Samples from PBT were prepared by injection molding and their mechanical properties were tested by tensile test and Shore hardness test.
Most published studies of such recycling have dealt with the effect of re-processing on the mechanical properties [4, 5].
Both mechanical and thermal properties are much better than in case of standard polymers [7, 8].
PBT Valox 4631 is a 30% glass reinforced, flame retarded PBT injection moulding resin with good electrical properties and excellent mechanical properties.
As it is shown in SEM figures, the glassy fibers after tests were broken, what can affect the decreasing of measured values of mechanical properties.

The behavior of RC walls under fire exposure is affected by various factors, such as slenderness ratio, concrete strength and composition, and axial load.
Previously conducted experimental studies have shown that several factors affect the behavior of RC walls under fire, including the concrete compressive strength, wall thickness, reinforcement ratio, axial load and lateral load levels, and boundary conditions, among others [10-16].
The effect of some of these factors was also studied in previous numerical investigations.
Moreover, mechanical properties needed for structural analysis include modulus of elasticity, compressive and tensile strengths, stress-strain curves, thermal expansion, and their variation with temperatures.
