Reduction of the dried red mud fines was done in an extended arc plasma reactor to recover the pig iron. Lime grit and low ash metallurgical （LAM） coke were used as the flux and reductant, respectively. 2level factorial design was used to study the influence of all parameters on the responses. Response surface modeling was done with the data obtained from statistically designed experiments. Metal recovery at optimum parameters was found to be 79.52%.展开更多

Tracheostomal myiasis is a rare entity, and only 7 such cases have been reported in literature. Our study emphasizes the importance of health education with regards to hygiene, sanitation and home tracheostomy tube care especially in immunocompromised individuals.展开更多
