In the last decade, developments in nanotechnology have provided a new field in medicine called “Nanomedicine”. Nanomedicine has provided new tools for photodynamic therapy. Quantum dots (QDs) are approximately spherical nanoparticles that have attracted broad attention and have been used in nanomedicine applications. QDs have high molar extinction coefficients and photoluminescence quantum yie...

Antibiotic guidelines for community-acquired pneumonia (CAP) often recommend broad-spectrum agents for severe pneumonia. While these may be entirely appropriate in terms of their spectrum of activity and efficacy, there is a risk that such recommendations could result in over-prescribing of broad-spectrum agents with consequent 'collateral damage', meaning superinfection by resistant pathogens,...

The semantic web should be about the meaning of humans with all the richness of cultural and historical dimensions. This paper suggests that a narrow group within the AI community has given too narrow a definition to the semantic web such that it excludes the human dimension. Even the approaches of the Dublin Core and W3 are not yet sufficiently broad. We need a new kind of cultural semantics i...
