Publikováno v: Journal of Forensic Sciences. 66:2208-2217

The issue of distinguishing between the same-source and different-source hypotheses based on various types of traces is a generic problem in forensic science. This problem is often tackled with Bayesian approaches, which are able to provide a likelih

Forensic profiling of human odor is challenging and would be useful to support information provided by dogs in courts of justice. Analyses of volatile compounds constitutive of human odor are commonly performed with gas chromatography coupled with ma

Les réalisations et les progrès de la chimie analytique sont l'occasion de raconter des récits, des enquêtes policières au sens propre du terme, qui ne masquent pas une réalité scientifique impressionnante qui les rend possibles. La partie �
