The presence of highly toxic cyanides in the effluent of coke oven of steel industries is considered as a critical problem. Owing to high levels of toxicity, control and removal of cyanide are of great importance in this industry. Biological removal of cyanides by indigenous microorganisms offers inexpensive, safe and environmentally compatible option in comparison with chemical and physical methods. The present study primarily focused on the isolation and purification of the microorganisms which utilize cyanide as the sole source of Nitrogen in alkaline conditions. The isolated bacterial strains were investigated through variety of bacteriological and biochemical reactions as well as... 

Combining the concept of Network-on-Chip (NoC) with three dimensional integrated circuits technology on 3D NoC enables reduction of propagation delay, interconnect power consumption, and die area, as well as increase in system operational bandwidth. Nevertheless, reducing the feature size of semiconductor technologies has raised certain aging mechanisms, like Negative Bias Temperature Instability (NBTI) and Electromigration, as the main reasons for reduction in reliability and lifetime of NoCs. Reduction in die area results in an increase in power density of the chip, which exacerbates temperature-related concerns of 3D NoCs compared to 2D NoCs. Thus, the aging mechanisms that are directly...
