[Characteristics of stab wounds inflicted by knives with the gear-sharpened blade].

The authors present the results of an experimental study designed to estimate the damage to biological and non-biological objects inflicted by the knife blades having the gear-type sharpening. It was shown that a knife with such sharpening leaves edges of the damage of characteristic shape and outline. The results of the study testify to the expediency of further studies on the damaging action of knives considered in the present paper.

[Detection and investigation of microparticles of biological tissues in gunshot wounds].

We studied feasibility of expert purposes solution in examination of gunshot bullet injuries by investigation traces of microparticles of tissues expulsed from the wounds and settled near the victim. Laws of such traces formation are established, feasibility of localization of the place of wounding, of the shot direction finding, definition of the gender, group, species of bioobject is shown.
