Paper and pulp industrial waste waters are a major environmental concern. As the treatment of these effluents is a major problem, exploring novel and feasible biotechnological interventions is very important. Utilization of white rot fungi as a means of biological treatment seems to be a viable option. The study was undertaken to use immobilization technique and Phanerochaete chrysosporium, a c...

This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive ...

in this paper we investigated effect of economic uncertainty on money demand function of iran during(1352-1386). at first by using a general equilibrium theory it is shown that in spite of the existence of economic uncertainties, most of agents who are risk-averse consider these uncertainties when constitute their port folio. they consider money demand is a function of income, interest rate and...
