Effect of normal load on the wear and rolling contact fatigue behaviour of AAR class B wheel against R350HT rail in a twin disc simulator

The normal load at the wheel-rail contact interface plays a significant role in wear and rolling contact fatigue (RCF) performance of both wheel and rail steels.In recent years, there has been an increase in axle loads due to increased demand for Batteries and Battery Products railway services.This study investigated the effect of normal load on th

Resolving the paradoxes of irrigation efficiency: Irrigated systems accounting analyses depletion-based water conservation for reallocation

The irrigation efficiency paradox says that raising the efficiency of irrigation systems, thereby reducing return flows, either gives no change in water depletion or it raises depletion via increased evapotranspiration and irrigated area.While this paradox can occur, there are problems associated with it.It eludes precise explanation and characteri
