Uniaxial Compressive Strength - an overview ...

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c …

Three Basic Principles of Utilitarianism - ThoughtCo

Utilitarianism is one of the most important and influential moral theories of modern times. In many respects, it is the outlook of Scottish philosopher David Hume (1711-1776) and his writings from the mid-18th century. But it received both its name and its clearest statement in the writings of English philosophers Jeremy Bentham (1748-1832) and John Stuart Mill (1806-1873).
