Effect of the rail surface topography on wear and fatigue
This study is an investigation of the impact of grinding-generated surface roughness on the wear and fatigue life of rails. The grinding process, essential for rail maintenance, creates a rough surface that significantly influences wheel/rail contact ...

Moral Tolerance: The Ethics of Social Punishment in Cases of Moral Disagreement
Theoria, EarlyView.ABSTRACT In many practical contemporary contexts, people need to make correct ethical judgements about how to respond to perceived wrongdoing—in particular, whether to punish it or tolerate it. This judgement can be challenging when the wrongdoer does not accept the allegation of wrongdoing at the level of moral principle, holding that the type of ...
