TL;DR: Osseointegration is the stable anchorage of an implant achieved by direct bone-to-implant contact in craniofacial implantology and this mode of anchorage is the only one for which high success rates have been reported.

TL;DR: The carcinogenicity of polycyclic aromatic hydrocarbons (PAHs) is associated with the complexity of the molecule, and with metabolic activation to reactive diol epoxide intermediates and their subsequent covalent binding to critical targets in DNA.

TL;DR: In this paper, a detailed overview of developments in transducer materials technology relating to their current and future applications in micro-scale devices is provided. And a short discussion of structural polymers that are extending the range of micro-fabrication techniques available to designers and production engineers beyond the limitations of silicon fabrication technology is presented.

TL;DR: In this paper, the emissions of a large number of chemical compounds emitted from birch wood combustion in a wood stove were analyzed and the results were compared to the size distribution in road traffic emissions.

TL;DR: In this paper, a combination of measurements and modelling is used to assess the contribution from road traffic emissions of heavy metals in urban air, and the results showed that more stop and go driving in the street compared to in road tunnels is likely to increase emissions.
