Experimental Investigation of the Cubic, Cylindrical, and Pile-shaped Obstacles on the Motion and Control of the Body of Saline Density Current [PDF]

مهندسی منابع آب, 2023
Introduction: The use of obstacles in dam reservoirs is considered an effective method for directing sedimentation toward the middle of the reservoir (instead of sedimentation next to the dam wall where the facilities are located).

A discussion on the order of magnitude of corrosion current density in reinforcements of concrete structures and its link with cross-section loss of reinforcement

RILEM Technical Letters, 2022
This paper deals with the determination of the corrosion current density in chloride-induced corrosion in reinforced concrete structures. Because the corrosion of steel bars is generally localized, calculations of the densities of corrosion current need

Effects of cylindrical and cubic piles on motion of density currents

Građevinar, 2021
Density current is the motion of a fluid in another fluid of a different density, with frequent negative environmental impacts. According to the deposition problems caused by density currents in the vicinity of dam bodies, attempts are usually made to ...

The Magnetic Response of Starphenes

Chemistry, 2021
The aromaticity of [n]starphenes (n = 1, 4, 7, 10, 13, 16), as well as starphene-based [19]dendriphene, is addressed by calculating the magnetically induced current density and the induced magnetic field, using the pseudo-π model.
