Fenthion (O,O-dimethyl-O-[3-methyl-4-(methylthio)-phenyl]-thiophos-phate ) is an organophosphate insecticide. A specific method to quantitate fenthion in postmortem matrices with solid-phase extraction combined with high-performance liquid chromatography-diode-array detection (HPLC-DAD) and gas chromatography-mass spectrometry (GC-MS) is presented.(More)
Low-cost architectures based on the transient response of passive circuits are used for the generation of UWB pulses. The input signal is produced by a commercially available ECL gate. Several prototypes were developed for various frequency masks imposed by the regulation authorities. It is shown that in each case the spectral density of the generated(More)
The safety of personnel is of a major concern when using and manipulating hotwire electric detonators. A lot of publications exist regarding the influence of electric fields on electric detonators. Most of them give safety distances in function of the E.I.R.P. (Equivalent Isotropic Radiated Power) taking into account several hypotheses, like the maximum(More)
