Influential breeders, among them Arthur Hancock of Kentucky and George Strawbridge of Pennsylvania, said the repeated use of diuretics and painkillers on young horses has resulted in a weaker strain of animals more prone to injury and is responsible for a general decline in the quality of American-bred animals.

Metallic stents made of materials with lower yield stress and weaker strain hardening tend to experience higher deformation and stronger dogboning and recoiling, but less residual stresses.

What's more is, we found that the combination of methanol and SVH displayed a significant synergistic effect on CA accumulation even with a weaker strain, which suggested its great application potential in fermentation.

Growth assays on a range of other sugar and nonsugar carbon sources revealed F2 was also diminished on lactose and maltose, while the apparently weaker strain F0 outperformed F2 on most non-sugar carbon sources tested, except ethanol.

The extended finite element method (X-FEM) is a numerical method for modeling strong (displacement) as well as weak (strain) discontinuities within a standard finite element framework.

However, the improved phase affinity makes the system more sensitive to the strain-responded deformation, leading to the reinforced Maxwell spring unit during creep and to a weak strain overshoot during dynamic flow.
