Abstract:
The concentration of heavy metal levels (Cd, Cu, Hg, Ni, Pb, and Zn) were assessed in water samples from Panvel creek, District Raigad, Maharashtra, West Coast of India. The heavy metals were analysed by using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). Results of the study reveal that, Cu, Ni, Zn, and Hg were detected in water samples of Panvel creek whereas Pb and Cd were not reported. Levels of Cu range from not detectable to 0.037 ppm whereas concentration of Ni varies from not detectable to 0.048. Zn is the only metal which is consistently detected at both the sites

Scientists and engineers still debate the relative contributions of roughness and interlocking of asperities, adhesion and interatomic forces, and elastic and plastic deformation in friction phenomena.

Therefore any mechanism that allows for this energy dissipation during sliding interactions of materials deserves consideration, whether it occurs strictly at the nominal sliding interface or within material at some distance from that interface.If the interaction

However, aluminum occurs in detectable amounts in natural waters, due to leaching of the soil minerals in acidic conditions.

Abstract The corrosion behaviour of magnesium alloys is not substantially comparable to other light metal alloys, it is more similar to that of steels. Voluminous reaction products, formed in neutral electrolytes, leads to a diffusion controlled dissolution on the surface of the underlying magnesium alloy. Therefore, influences from structure and alloying are suppressed very strongly. In alkaline environments, passivation occurs as a result of the formation of a hydroxide layer on the magnesium surface. Therefore, differences in the corrosion behaviour between the alloys are hardly detectable.
