Digital image correlation (DIC) is a photogrammetric method that allows reconstruction of displacement and strain fields from the surface images. The displacements and strains are reconstructed by correlating sections (subsets) of the reference and deformed images generally taken before and after deformation respectively. Traditionally, DIC is applied to grayscale images taken with monochromatic cameras,...

Treatment of chicken liver fructose-1,6-bisphosphatase with oxidized glutathione (GSSG) leads to an increase in activity. This activation is markedly enhanced if treatment is performed in the presence of AMP or Mn 2 + . The effects of AMP and Mn 2 + appear to be synergistic. The maximal activation is over 13-fold and is accompanied by the disappearance of 4 sulfhydryl groups...
