However, El-Hilo et al. who interpreted that the formation of NiO grains by there are the part of Ni ions did not enter in the crystalline structure of ZnO due to the limitation of the solid solubility of Ni in ZnO [13].

Arias (2002) studied the characteristics of copper and cadmium on kaolin by the presence of humic acids and the selected experimental pH values ranging from 4 to 7[2]; El Habib (2010) selected pH values ranging from 4 to 7 as the experimental condition to study the pH effect on imazethapyr adsorption onto montmorillonite (M), Cu-montmorillonite (Cu-M) and Cu humic acid - montmorillonite (Cu-HA-M)[3].

Al-12.7Si-0.7Mg alloy is a novel wrought Al-Si alloy which has superior mechanical properties after heat treatment [4,5,6].
In this paper, a novel heat-treatable Al-5.4Si-0.5Mg welding wire was prepared and was used to weld the Al-12.7Si-0.7Mg alloy.
Al-12.7Si-0.7Mg alloy were butt welded using the Al-5.4Si-0.5Mg welding wire as the filler metal.
Conclusions The as-produced Al-5.4Si-0.5Mg welding wire was an ideal special filler wire for the novel Al-12.7Si-0.7Mg alloy.

El Refai et al. [8] studied different types of BFRP bars, specifically ribbed and sand-coated, by performing pullout tests after subjecting the bars to harsh environmental environments.
Elgabbas et al. [9] studied the tensile behavior of BFRP bars after being immersed in an alkaline solution at 60°C for up to 3000 hours to replicate concrete-like conditions.
To evaluate the mechanical properties of BFRP-reinforced concrete structures, Alkhraisha et al. [7] studied the flexural strength of concrete beams reinforced with BFRP bars under severe exposure conditions.
Such variation in the compressive strength of BFRP bars at high strain rates was also observed by Abed et al. [12].

Various authors like Agarwal et. al [2], Shukla and Isa [3], Verma [4], El-Kayar et. al [5], Elsharkawy et. al [6] and Jaw-Ren Lin [7] have studied the flow behavior of various lubricants in an externally pressurized thrust bearing under different conditions.
J S Roy et. al [8] discussed the effect of inertia forces in an externally pressurized thrust bearing with variable film thickness using visco-elastic lubricants.
