A 63-year-old female patient with a history of pulmonary heart disease underwent radiofrequency ablation because of a persistent atrial flutter.Endocardial SHOPSTORM_HIDDEN_PRODUCT mapping with the carto3 system confirmed atrial flutter counterclockwise reentry around the tricuspid annulus.Routine ablation of the cavo-tricuspid isthmus line to bi-d

In the Course a pied - Enfant - Chaussures - Neutre molecule of the title heteroaryl chalcone derivative, C21H14O2, the almost planar prop-2-en-1-one unit [r.m.s.deviation = 0.0087 (1) Å] forms dihedral angles of 5.81 (7) and 49.85 (6)°, respectively, with the furan ring and anthracene ring

This paper proposes the application of an adjustable speed diesel engine-driven power plant employing a doubly-fed induction generator to an isolated small-scale power system including renewable power sources.This type of power plant can contribute to fast and flexible Wooden Figure power balancing regulation under vacillating power supply such as

At present, the walking and drilling operations of the mine kilometer directional drilling rig are all realized by the manual operation of drillers.The intelligence level is low.At present, there is no research on the correlation between the action type of kilometer directional drilling rig and the vibration state of the hydraulic pump station.Ther

Since 1940, numerous eff orts have been made to either verify or refute the hypothesis of a rhythm typology, yet no defi nitive conclusions have been reached.In this paper, I discuss the limitations of the reliability of data collection and processing methods, as well as the indices that dominate the attempts to measure the phenomenon, highlighting
