EVALUATION OF THE AERODYNAMIC EFFECT OF A SMOOTH ROUNDED ROOF ON CROSSWIND STABILITY OF A TRAIN BY WIND TUNNEL TESTS

Evaluation of the Aerodynamic Effect of a Smooth Rounded Roof on Crosswind Stability of a Train by Wind Tunnel Tests

The advent of high-speed trains led to new issues and constraints for Chandeliers railway network manufacturers and operators.This is the case of crosswind effect, that occurs when train is running in strong wind conditions.The combination of train speed and wind speed generates a relative flow that affects the train stability.Wind tunnel tests on

New mitotic regulators released from chromatin

Faithful action of the mitotic spindle segregates duplicated chromosomes into daughter cells.Perturbations of this process result in chromosome mis-segregation, leading to chromosomal instability and Tea cancer development.Chromosomes are not simply passengers segregated by spindle microtubules but rather play a major active role in spindle assembl
