This study presents the experimental verification of a damage monitoring and evaluation method for building structures based on the measurement of Relative Story Displacements (RSDs). The damage evaluation method is formulated to detect the damaged locations of structural elements and evaluate their damage degree based on the displacement loading analysis by the time histories of measured RSDs....

To investigate the microstructure and damage of friction-fatigued carburized martensitic steels for reliability remanufacturing parts, retained austenite (γ) phase residual stress were characterized by X-ray diffraction (XRD) scanning electron microscopy (SEM). We evaluated their changes before after roller pitching tests, operation gear parts.

Plants contain enriched bioactive molecules that can protect against skin diseases. Bioactive molecules become unstable and ineffective due to unfavorable conditions. In the present study, to improve the therapeutic efficacy of phytodrugs and enhance photoprotective capability, we used poly(D,L-lactide-co-glycolide) as a carrier of apple peel ethanolic extract (APETE) on permeation-enhanced nan...
