Brinell and Vickers Hardness Measurement Using Image Processing and Analysis Techniques
Mechanical hardness testing is fundamental in the evaluation of the mechanical properties of metallic materials due to the fact that the hardness values allow one to determine the wear resistance of the material involved, as well as the approximate values of its ductility, flow tension, among a number of other key characteristics. As a result, the main objective of the present work has been the...
متن کاملInvestigation acute toxicity some of the heavy metals at different water hardness
All aquatic organisms are directly or indirectly affected by the physical characteristics of their environment, especially the chemical composition of the water. The high concentration levels, damage tissues and interfere with the normal growth and proliferation. The aim of this research was to Investigation acute toxicity of ZnSO4 and CuCl2 to Gambusia holbrooki ...

متن کاملRemoval of heavy metals and hardness from groundwater via electro-coagulation method
Groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. This study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
