The structure of a sound speed profile (SSP) in deep water causes refraction rays and Convergence Zones (CZs) high intensity where the focus at shallow depth. Study field characteristics CZs has always been deep-water acoustics research. Many studies have conducted on propagation different parts oceans with environments and, this paper, range width CZ is analyzed East Indian Ocean (EIO) South C...

This paper presents an overview of the characteristics potentially influencing profile vortex shedding (PVS) phenomenon being relevant in noise and vibration low-speed axial fan rotor blades. Dimensional analysis has been applied to explore essential dimensionless quantities a systematic comprehensive manner. On this basis, limitations have established, simplifying assumptions set up terms PVS ...

To explore the formation mechanism of residual stress in high-speed grinding noncircular equidistant profiles, orthogonal experiments three parameters—the wheel speed, workpiece and depth—were designed. A ceramic bond CBN was used for profile by X-C axis linkage. The effects parameters on temperature, surface roughness, were analyzed. results show that with increase temperature increase, roughn...

Objective(s): We examined the effects of endurance exercise in the presence of Bunium persicum extract administration on lipid profile and cardiorespiratory capacity in hypercholesterolemic male mice. Materials and Methods: Forty male hypercholesterolemic mice were divided into four groups: Vehicle, Endurance exercise (EE), Bunium persicum extract (BPE), and EE + BPE. The exercise protocol was ...

The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc.). On the other hand, they are extremely expensive, mainly due to high installation and maintenance cost of the catenary system, including...
