Secondary organic carbon (SOC) is often a significant portion of organic carbon (OC) in ambient particulate matter (PM). The levels and seasonal patterns of SOC in Hong Kong were examined using more than 2000 PM 10 measurements made over a 4.5-year period (1998–2002) in a network of ten air quality monitoring stations.

This study explored three dimensional (3D) talonavicular joint (TNJ) coverage/orientation and bone morphology to reveal parameters that could classify and identify predispositions to cavus and planus feet. 3D models of 65 feet from 40 subjects were generated from computed tomography images classified as pes cavus, neutrally aligned, or(More)
