The prospect of providing city visitors with dynamic and context-sensitive multimedia information whilst on the move is both novel and exciting and raises many interesting research issues. The GUIDE project is currently examining these issues by developing systems and application-level support for hand-portable multimedia GUIDE units with wireless network connectivity, enabling context-sensitiv...
Panel studies show a consistent association between increase in the cardiovascular hospitalizations with air pollutants in economically developed regions, but little evidence in less developed inland areas. In this study, a time-series analysis was used to examine the specific effects of major air pollutants [particulate matter less than 10 microns in diameter (PM(10)), sulfur dioxide (SO(2)), ...
Silver nanoparticle deposition from suspension is proposed as a route for the morphological design of controllably disordered self-affine substrates for surfaceenhanced Raman sensing of water pollutants. Ionic strength is used as a variable parameter to control the deposition process and, ultimately, the morphology of deposited substrates. The critical dependence of the enhancement factor on th...
BACKGROUND The elevation and dissipation of pollutants after the ignition of fireworks in different functional areas of a valley city were investigated. METHODS The Air Quality Index (AQI) as well as inter-day and intra-day concentrations of various air pollutants (PM10, PM2.5, SO2, NO2, CO, O3) were measured during two episodes that took place during Chinese New Year festivities. RESULTS F...
