El-Sherik et al. reported increasing sulfur contents in the deposit with increasing saccharin addition [9].
Yamaguchi et al. have shown that sulfur induced embrittlement of nickel [10].
The present result is compared with those of Ebrahimi et al. [11], Torre et al. [12], Gu et al. [13,14], Shen et al
[15] and Prasad et al. [16], who used electrodeposition to produce nickel specimens.

Gupta el al. [3] investigated the bahaviour of pure aluminum plates varying from 0.5 to 2 mm impacted by ogive-nose steel projectiles.
Forrestal et al. [5] conducted experiments with 0.026 kg mass, 8.31 mm diameter conical-nose tungsten projectiles and 12.7, 50.8 and 76.2 mm thick aluminum plates of AA5083-H131.
Børvik et al. [6, 7] performed perforation experiments and calculations with 15-30 mm thick AA5083-H116 aluminum plates and 20 mm diameter, 98 mm long, HRC 53 conical-nose hardened steel projectiles.
Swaddiwudhipong el al. [8] studied the perforation of Weldox 460E steel and AA5083-H116 aluminum plates with varying thicknesses and various projectile nose geometries including bunt, conical and ogival noses, adopting the coupled smooth particle hydrodynamics - finite element method.
In order to examine numerical procedures, the geometry configuration of the projectile-target plate system was taken to be identical to the one designed by Børvik et al. [6].

El-Sebaii et al [2] studied the performance of a single slope still with Phase Change Materials (PCM) as a storage medium and the daily efficiency of 84.3 % was achieved by the PCM incorporated solar still.
Sakthivel et al [3] studied the regenerative solar still with jute cloth as an energy storing material.
Abdallah et al [4] used a suntracking device for rotating the solar still with the movement of the sun.

In figure 1 it is observed that the main elements slag containing are Al, Mg, Cl, Na, K, O, Si, with traces of F and S.
In figure 2 the XRD analysis shows a rich aluminum and magnesium slag, with metallic aluminun as well as Al, Mg and Cu oxides, in addition containing KCl (Silvita), NaCl (halite), SiO2 (quartz), principally.
Both compositions correspond to a hypoeutectic Al-Si alloy (<12 wt% Si).
