abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...

Nowadays, energy extraction from sea waves as a renewable energy source has been increasingly considered. In addition, the growing demand for energy as a result of development of industrial activities, air pollution caused by the use of fossil fuels and greenhouse problems caused a new challenge for humankind. Tidal energy is a type of energy that is derived from converting the tidal power of t...

now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...

Abstract Several methods have been developed such as experimental methods, numerical and computational models for studying the prediction of water level. The purpose of this research is to evaluate and verification Telemac's numerical tidal model in Bushehr Bay waters using measured data. In this regard, the Telemac 2D module has been used to simulate the tide in a A course, 15 days from 01/08...
