berthing force is a critical dynamic lateral force in the design of berthing structures, having equal relevance when compared to seismic forces. besides, the construction cost of berthing structures is very high which can be optimized by calculating precise design berthing energy on fender and selecting optimum fender system. in the present study, design berthing energy of bulk carriers having ...
Tamarix sricta plant grows in riversides of Karun river. Outer body plant in the flood times causes decrease in water velocity, preventing erosion. One of the factors by which the hydraulic resistance is expressed is the roughness coefficient. Measurement of roughness coefficient of the existing plants in these riversides and floodplains, and surveying their effects on the velocity decrease and...
A critical air velocity analysis was performed using a numerical model adapted for the eastern tunnel tube of Kastelec road in Slovenia. This allowed efficiency fans to be tested, which is required maintain appropriate traffic conditions and prescribed safety tunnel. At velocity, that is, at an lower than one, where spread smoke can still effectively controlled ensure time safe evacuation passe...
oily wastewaters from oil refineries and oil distribution centers are one of the most important environmental concerns in recent decades; therefore, it is critical to treat these types of wastewaters. in this study, the performance of different polyethersulfone hollow fiber membranes in oily wastewaters treatment was investigated and the effects of operating conditions such as transmembrane pre...
