single storms are the most restore water at the water management especially in arid and semi arid. therefore, single storm estimation is the important step in risk management. this study, single storm estimated by gsdm model. so, the date used include: meteorological data, dem and water value in basin jahanbin. in the gsdm model should divide basin to two region smooth and rough, moisture adjus...

The Weibull distribution has received much interest in reliability theory. well-known maximum likelihood estimators (MLE) of this fam ily are not available closed form expression. In work, we propose a consistent and estimator for shape parameter three-parameter distribution. Apart from high degree performance, the derived is location scale-invariant.

A new commercial formulation, F2, was evaluated as a protectant of stored wheat, stored maize, and stored rough (paddy) rice. This formulation comprises the technical active ingredients 0.03% deltamethrin, 0.37% piperonyl butoxide, and 0.95% chlorpyriphos-methyl, plus 10% mineral oil and 88.0% of the diatomaceous earth Protect-It. Tests were conducted with dust and slurry formulations at 50 and...
