This is equivalent to a 1.3 percent reduction from the 2006 baseline level of 2588.8 million tons [3].
Emission reduction is still a long term task for environmental protection [4-6].
In present work, we do the field experiments and collects mass of data.

After thorough cleaning and brushing, the Al and Al(Sc) sheets were
mechanically stacked and held for 5 min at 350°C in a preheated air circulating furnace and rolled
without lubrication in a single-pass to 50% reduction using a two high laboratory rolling mill.
After six cycles and a final rolling pass of 50% reduction, 0.5mm thick sheets containing 64 alternating layers were produced.
Standardized tensile test pieces (ASTM-E8) with nominal dimensions of 50 × 5 × 0.5 mm were tested using an INSTRON-1185 Universal Testing System and the tensile data was analysed using Origin-6.0 software.

Figure 1: Changes of pH for tap water and B.cereus seeded water during retting period.
From the result, the pectinolytic enzyme secreted might be effective on alkaline as the reduction of pH was huge from day 1 to day 0.
Supposely, the B.cereus seeded water have higher pH reduction compare to the tap water retting.

As can be seen, for
both layups, a clear reduction in fatigue life takes place especially at high stress levels.
The reduction in fatigue limits between the dry and wet material is 8.2 and 9.7% for the quasi-isotropic and cross-ply laminates, respectively.
Due to lack of precise data describing the property degradation of the Fiberdux/HTA6376 lamina as a function of water absorption, it was assumed that the degradation in the lamina stiffness's and strengths corresponds to the degradation in specimen's stiffness and tensile strength, as evaluated from the experiments (see Table 1).

Reduction in particle size improved the morphology of the YBCO film, and it is a useful technique to minimize cracking of coatings[10].
By comparing the data of the XRD pattern of YBCO powder in Fig.1, it was confirmed that the peak values of (00l) increased.

As suggested by the CV data, the peak AIII corresponds to the formation of Fe (V) species seen in Eq. 4.
Fe+2OH—→Fe(OH)2+2e (2) Fe(OH)2+2OH—→FeO2—+2H2O+e (3) FeO2—+ +2OH— → FeO43-+ 2H2O+2e (4) 3FeO43-+ 2H2O → FeO42-+ FeO2—+4OH— (5) 4 OH— →O2+2H2O+4e (6) Three cathodic current peaks are observed and attributed, one each, to the reduction of Fe(VI) to Fe(III), of Fe(III) to Fe(II), and of Fe(II) to Fe(0).The peak CIII corresponds to the reduction of ferrate(Ⅵ) according to the following Eq.7[5].

Early experimental studies have provided data on the strength of filament- wound GFRP thin-walled cylinders under combinations of internal pressure and axial loads [6-8].
Fig. 3B is showing a high increase of circumferential displacement at θ=30°, which is the result of patch load boundary condition, then the displacement is decreasing because of sudden reduction of force to the value of zero.
Displacement and Stress resultant for different thicknesses of layers According to fig. 3, the curves are indicating that, the stresses and displacements responses of the cylinder shell are not varying properly for ply thickness reduction from 1mm to 0.1 mm.

The specimens were reheated at 1000˚C for 300S and rolled with two pass schedule, resulting in a reduction of 25% and 30% at 950˚C and 900˚C, respectively.
The refinement of bainitic ferrite by increasing the cooling rate could be due to the following: when the cooling rate increases, the reduction in the bainite transformation start temperature (Table 2), Bs, lead to an increase in the driving force (the difference in free energy between the austenite phase and the ferrite phase) for the nucleation rate of substructures of ferrite and, consequently, to a decrease in the width of the bainitic ferrite laths.
The EBSD measurements data were used to analyze the local grain orientation, the grain size and the grain boundary character distribution.
