Statistical data analysis Statistical analysis was performed using the software SPSS 13.0.The results were subjected to a one-way ANOVA using the Tukey test to check for significant differences between means (P<0.05).
Maximum reduction of all growth parameters were observed at 200mmol/L NaCl.

Introduction Use of advanced welding technologies for aluminium alloys is considered as an essential longterm alternative to the conventional riveted airframe structures because of its potential in weight reduction.
The peak centers, widths and intensities were obtained by least squares fittings a Gaussian line shape to the experimental data.

There are several experimental confirmations that considerable enhancement of creep resistance at high temperatures can be achieved by reduction of carbon content that leads to numerous precipitations of (Nb,V)(C,N) nanoscaled carbonitrides instead of relatively coarse M23C6-type carbides [7].
Figure 1 shows the Laves-phase particles, which were formed after ~500 (а), 1500 (b), ~6000 (c) and ~16000 (d) hours in the gauge portion of crept specimens along with the EDS data for the indicated particles.

Among the series of LiNixCoyMn1−x−yO2, the Ni-rich compounds (x ≥ 0.5) such as LiNi0.5Co0.2Mn0.3O2 have drawn considerable attention recently because high Ni content contributed to the improvement of specific capacity and the reduction of cost[8-10].
The data are collected from 10.0°to 80.0° with a step size of 0.02°.

The experimental data were taken in the etching solution of 22.5 M HF-0.05 M Na2S2O8-H2O.
It is generally accepted that reduction of the oxidizing agent is a two-step reaction [14,15].

Thus, this method allows reduction of the computational cost while preserving a relatively good accuracy.
It is thus obtained the following expression: and (11) For numerical applications we can use the data of and determined by a 3D model on a simple 1D model under a dynamic loading as an unbalance.

Phosphorous slag occurs during reduction of phosphorous from phosphate rock in an electrical furnace.
Likewise, literature data [5, 6, 9-12]suggest the possibility of using phosphorous slag in cement-based materials as a supplementary cementitious material, which will reduce damage to the environment and help in saving natural resources.
