Ventricular fibrillation (VF) is one of the main causes of death in the Western world. According to one hypothesis, the chaotic excitation dynamics during VF are the result of dynamical instabilities in action potential duration (APD) the occurrence of which requires that the slope of the APD restitution curve exceeds 1. Other factors such as electrotonic coupling and cardiac memory also determ...

Slope instability phenomena are among the most hazardous natural events affecting our society, and therefore physical–mechanical behavior of rock masses with reference to these is a relevant topic for engineering geological practice, as it conditions realization functionality structures infrastructures, well quality life economy [...]

Air transmission lines generally use ACSR type conductors. As the demand for electrical energy increases, effort to increase capacity of line is carried out by optimizing current-carrying existing line, but problem that arises in this optimization voltage and slope conductor. This study aims determine effect current instability on conductor temperature, slope, angle voltage, which then useful c...

Instability of submarine slopes in Zhoushan Islands is widespread. Frequent landslides pose a great threat to offshore facilities such as optical cables, reclamation projects, ports and docks. In this paper, self-developed in-situ observation system used observe the deformation on southwest side Zhujiajian Island for 75 days. The results show that characteristics sediments at different depths s...

A theoretical study of the transformation of large amplitude internal solitary waves (ISW) of permanent form over a slope–shelf topography is considered using as basis the Reynolds equations. The vertical fluid stratification, amplitudes of the propagating ISWs, and the bottom parameters were taken close to those observed in the Andaman and Sulu Seas. The problem was solved numerically. It was ...

Abstract The Florida Current (FC) flows in the Straits of (SoF) and connects Loop Gulf Mexico to Stream (GS) Western Atlantic Ocean. Its journey through SoF is at time characterized by formation presence mesoscale but mostly submesoscale frontal eddies on cyclonic side current. those was investigated a very high resolution two-way nested simulation using Regional Oceanic Modeling System (ROMS)....
