"I think those information and advice and guidance services that help people who haven't quite tipped into severe distress are the things that I most wish we still had.
Severe feeding at the tip of kernels allows entry for diseases and mold growth.

That would, indeed, constitute a major tipping point, with severe consequences for Europe and eastern North America.
For micro-cracks usually with width-to-depth far much less than 1, the light field intensification is more severe than those with rounded tips.
The dissolution of the Cu particles was suggested to be caused by a dynamic partitioning of Cu atoms from the precipitates into the matrix by dislocation shearing at the particle tip sharpened by severe cold working.
However, the local stress fields in single edge notched tension, SE(T), specimens and pipes, for example, are known to be less severe than those at the tip of a deep sharp crack, resulting in an increased capacity to sustain load and higher toughness.
(if not handled with protective gloves through their life, the situation will become comparable to a very small and speedy untame dog) They are known for drawing blood and, in severe cases, slightly removing the tips of offending fingers when they bite.
