The effect of deformation on the evolution crystallographic texture in a Ti-15V-3Cr-3Sn-3Al (Ti-15333) alloy after unidirectional cold rolling was studied experimentally and numerically present investigation. An optical microscope (OM) scanning electron (SEM) were used to study microstructures, while with X-ray diffraction. process (deformation) simulated PRISMS-plasticity, open-source crystal ...

Electron backscatter diffraction (EBSD) is used to investigate crystal lattice rotation caused by plastic deformation during high-strain rate laser shock peening in single crystal aluminum and copper sample on ~11̄0! and (001) surfaces. New experimental methodologies are employed which enable measurement of the in-plane lattice rotation under approximate plane-strain conditions. Crystal lattice ...

Crystal plasticity involves the motion of dislocations under stress. So far, atomistic simulations of this process have predicted Peierls stresses, the stress needed to overcome the crystal resistance in the absence of thermal fluctuations, of more than twice the experimental values, a discrepancy best-known in body-centred cubic crystals. Here we show that a large contribution arises from the ...

objective brain abscesses represent organized foci of suppuration within the parenchyma. here we report a 3 month-old girl with a very huge complicated cerebral abscess, and the course of treatment given. the patient's recovery was excellent. the follow up mri showed only subtle porencephalic changes as the only parenchymal sequelae, which may be due to cns plasticity in infants.

migraine is a primary headache which is very common in the society. although it is usually starts in a salient point in life span of an individual diagnostically, the repetition of acute stress response such as sleep abnormalities, anxiety, and depression are not new in this population. therefore, they have had almost a long diary of these abnormalities. in order to understand the role/s of str...
