a design discharge is an important issue in the design process of pressurized irrigation networks. underestimating the desing discharge affect, the required pressure and offtake discharge, increase the cost of the network. because of the lack of a standard and reliable method for this propuse, usually different approches are used by designers. the network fails to provide the required flow rate...

Background and aims: One of the innovative technologies for air pollution control is non-thermal plasma. The dielectric barrier discharge reactor is one of the reactors that applied in non thermal plasma technology for air polluation control. In dielectric barrier discharge reactor, the distance between the electrodes for electric discharge is low and led to increasing space velocity of the pol...

this paper seeks to emphasize the flow variability in the calnistea catchment by analyzing the local physiographic factors. the research has shown that the amount of precipitation that falls to the ground is low, the rocks in the region are soft, but highly permeable, gradients are gentle in most of the territory and vegetal cover is sparse and therefore cannot hold important amounts of water. ...

aim and background: the present study aimed to investigate the symptom severity and quality of life in patients suffering from bipolar disorder. methods and materials: this longitudinal and prospective study was done on 20 patients with bipolar type i disorder who were hospitalized in noor hospital of isfahan, iran. patients were evaluated before hospitalization, at the time of discharge, 3 and...

The piano key weir (PKW) is a type of nonlinear control structure that can be used to increase unit discharge over linear overflow weir geometries, particularly when the weir footprint area is restricted To predict the outflow passing over a piano key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of...
