The predominant biological hypothesis for a neurochemical defect in schizophrenia is currently the socalled "dopamine (DA) hypothesis." In its simplest form, this hypothesis states that schizophrenia may be related to a relative excess of DA-dependent neuronal activity. It is derived from pharmacologic evidence that drugs that decrease DA activity (e.g., the phenothiazines) may be antipsychotic...

the estimation of instantaneous peak discharge is important for watershed management because there is ainsufficient climatic and hydrologic data in countries such as iran. researchers have been forced to link constantparameters (geomorphology) and variable parameters (hydrology) to models with minimum dependence on climaticand hydrologic data for hydrologic estimation. the present study used a ...
