The parameters that influence crack propagation are the operating conditions (loads by axle, speed, rolling stock characteristics…); track configuration and geometry

This paper examines volatility and correlation dynamics in price returns of gold, silver, platinum and palladium, and explores the corresponding risk management

Our results, using freshwater fish cell lines and a set of relevant cytotoxicity endpoints including cell viability, oxidative stress, and DNA damage, provide additional mechanistic

In all cases, the maximum and minimum stresses were 85% and 20%, respectively, of the average compressive strength of each size se- ries, and we kept these values through the

84% refer to physical activity on a daily basis, in addition to the fact that 65.4% of students consider themselves to be under moderate stress, 16.6% do not present stress, 15.5%

(a) Low lattice resistance (fcc metals and LiF) and (b) Intermediate lattice resistance (bcc metals) normalized shear yield stress vs. pillar diameter and power-law fit.

In not mated females the interest towards control males was highest towards first presented males, and no presentation order effect existed in mated females where

Abstract This paper addresses the problem of finding a static virtual topology design and flow routing in transparent optical WDM networks under a time-varying (multi-hour) traffic
