Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage.

Sexual jealousy functions to defend paternity confidence and is therefore expected to be a ubiquitous aspect of male psychology. Several lines of evidence confirm this expectation. Cross-cultural and historical reviews of adultery law reveal remarkable conceptual consistency: unauthorized sexual contact with a married woman is a crime and the victim is the husband. We find male sexual jealousy ...
