Objectives Sarcopenia, an age-related decrease in muscle mass and function, is associated with several potential adverse health outcomes. Its association with another age-related syndrome, dysphagia remains unclear. This systematic review and meta-analysis aims to explore the association between sarcopenia and dysphagia. Methods PubMed, Embase, Scopus and CINAHL were searched for cross-sectional,...
In this study, the influences of intermetallic compounds Cu6Sn5 at interface between solder and Cu substrate and Ag3Sn inside solder with different morphologies on the fracture behaviors of Sn-3Ag-0.5Cu/Cu solder joint were investigated. Cu6Sn5 grains became large in size with the increase of reflow time and aging procedure. Ag3Sn compounds appeared particle-like or branch-like morphologies as reflowed...
The mechanical toughness of poly(phenylene oxide) (PPO) thin films was found to degrade remarkably from physical aging and the fracture mode transformed from ductile shear into a brittle type that involved no stable deformation zone growth. In the beginning, the fresh PPO films deformed almost uniformly upon stretching up to more than 20% strain. However, when the film was isothermally aged, diffuse...
