Characteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
متن کاملSabine Ehrt: Searching for mycobacterial stress points
For most bacteria, getting scooped up by macrophages means a rapid death at the hands of a lethal cocktail of nitric oxide, free radicals, and destructive enzymes. Mycobacterium tuberculosis avoids this fate first by preventing the fusion of phagosomes with lysosomes in resting macrophages. The bacterium then turns off its replication machinery, allowing it to establish a latent infection. Sabi...

متن کاملThe SirT3 divining rod points to oxidative stress.
Sirtuins are NAD(+) dependent deacetylases that counter aging and diseases of aging. Sirtuin research has focused on SirT1, which deacetylates transcription factors and cofactors in the nucleus. More recent findings highlight SirT3 as a mitochondrial sirtuin that regulates metabolism and oxidative stress. This review focuses on new data linking SirT3 to management of reactive oxygen species fro...
متن کاملCrosstalk between abiotic and biotic stress responses: a current view from the points of convergence in the stress signaling networks.
Plants have evolved a wide range of mechanisms to cope with biotic and abiotic stresses. To date, the molecular mechanisms that are involved in each stress has been revealed comparatively independently, and so our understanding of convergence points between biotic and abiotic stress signaling pathways remain rudimentary. However, recent studies have revealed several molecules, including transcr...
