the photocatalytic decomposition of trichloroethylene (tce) and tetrachloroethylene (pce)in water was studied. tce and pce were present in water at very low concentrations of about 15 μg/dm3. thisconcentration level corresponds to the one occasionally occurring in groundwater. results of this researchconfirmed usefulness of the photocatalytic process for successful removal of low-concentrated t...

in iran’s system of tripartite collective bargaining, does the wage-policy maker consistently react optimally to the best move made by the exchange rate-policy maker (nash-rule) or only to the state of economy (non-nash rule)?. this paper not only investigates the nature of the political game (nash rule against non-nash rule) but also estimates some structural parameters by using 2sls method an...
