چکیده

1.531211SMJ8 Jeewanu, the autopoeitic eukaryote, was prepared under oxygenic conditions and the effect of addition of different concentrations of formaldehyde in the PEM on the degree of Mo the proton release during exposure to sunlight was investigated. It was observed that on exposure to sunlight, the colourless form Mo 6+ is changed to blue coloured Mo minutes of exposure. The intensity o photoelectric colorimeter. The pH of the five PEM solutions having different concentrations of formaldehyde was measured with the pH meter at different exposure period. The optimum Jeewanu took place only up to 5.68% formaldehyde concentration in the PEM. Further increase in the concentration of formaldehyde in the PEM hinders the Jeewanu formation. The increase in the photochemical release of protons with increasing period of exposure was sharper in lower concentrations of formaldehyde in the PEM

Performance improvement of the Sarcheshmeh Copper Complex Cu-Mo thickener using a vane type feedwell

Water plays a key role in mineral processing plants. In order to process one ton of ore, 2.5 ton water is needed. Thickeners are commonly used for dewatering and recovering the water in most mineral processing plants. The underflow pulp density is increased by the sedimentation of particles and a clear water is then recovered from the overflow. One of the issues related to using the process wat...

Effect of CO in the reformatted fuel on the performance of Polymer Electrolyte Membrane (PEM) fuel cell

There are several obstacles to the commercialization of PEM fuel cells.  One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...
