Square Wave Pulsed Electrodeposition of Chromium from Deep Eutectic Solvent (DES) Based on Choline Chloride
Abstract: Electrodeposition of chromium from hexavalent chromium ion is very toxic, carcinogenic, not environmentally benign, cathodic efficiency is low, and the quality of coating is very poor (due to H2 evolution). Ambient temperature Deep Eutectic Solvent (DES) can be formed by reacting choline chloride (HOC2H4 (CH3)3Cl) with metal salts. These low cost DES are not sensitive to air and moisture and have good electro-conductivity and they do not have vapour pressure. …

Individual and Combined Effects of Lead Rubber Bearing and Fluid Viscous Damper Techniques on Seismic Response of Irregular Reinforced Concrete Buildings
Abstract: Most old structures that do not meet current seismic regulations may sustain significant damage or perhaps collapse as a result of an earthquake. The seismic enhancement could potentially help people survive a major earthquake. Since earthquake engineering began, not only in India but also in other nations, earthquake-resistant construction of reinforced concrete buildings has been a constant topic of research. Buildings are still being damaged as a result of earthquakes. …

Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …
