Gunshot wounds of skin and long cortical bones inflicted by the special intelligence knife (NRS and NRS-2: special silent cartridges SP-3 and SP-4) from different distances were examined. Stereomicroscopy, emission spectral analysis, contact-diffusion method and regression- step-by-step analysis were made use of within the case study. A lack of mechanical, thermal or chemical impact from firing gas and of fire soot as well as presence of particles of rubber, copper and sealing varnish, i.e. the most informative shot products, were found to be the main distinctive features in the said wounds. The data obtained can be used in the differential diagnosis of a type and model of the used gun. 相似文献

Design philosophy of blades of Russia-made combat cold arms and of inflicted-by-them stab-and-cut wounds were characterized on the basis of a comparative-and-evaluation study. Stereomicroscopy, histology examinations as well as X-ray-spectral and fluorescence analyses were made use of while investigating the wounds with subsequent processing of the results by discriminative analysis. Form, skewness and a graze type of the wound tubber as well as presence of "edge cuts" and of central graze wound were found to be the main distinctive wound signs. The study results ensure a full-value differential diagnosis of a type of the used cold-arm sample. 相似文献
