A Rare Case of Homicide by Dual Method-Strangulation with Cut Throat: A Case Report

Background: Homicide is killing of a human being by another human being. Various methods like strangulation, cut throat, stabbing etc may be used for homicide; however combination of two mechanisms is rare.Case Report: hereby we present a rare case with unexpected appearance of two different mechanisms of homicide applied over same region, wherein body of a female was referred to us with history of cut throat. Body of the deceased was found near her house with cut throat injuries over front of neck, on examination cut throat injuries were present over neck along with ligature mark intermingling with them.Conclusion: The present case represents an unexpected rare association of two methods of homicide, as in this case of strangulation followed by cut throat. Correct Interpretation of cause of death with its manner in such case is very important, which needs meticulous post-mortem examination along with proper correlation with other information

Nanocrystalline Pentaerythritoltetranitrate using Sol-Gel Process

The secondary explosives developed with reduced particle size tend to be more insensitive for mechanical stimuli and may release energy with faster rate and gaining more importance nowadays. Therefore, aiming to reduce the particle size of one of the popular explosives, viz., pentaerythritoltetranitrate (PETN) to the nanometer range, a method for preparation of nanocrystalline PETN in the silica (SiO2) gel matrix using sol-gel process has been demonstrated. The PETN-SiO2 xerogels were prepared containing PETN content ranging from 50 per cent to 90 per cent (w/w) and the xerogels were characterised using different techniques. An exothermic peak at around 185 oC preceded by an endotherm in thermal analysis accompanied with weight loss in the temperature range from 150 oC to 200 oC   for the xerogel confirmed the presence of PETN in xerogel. Infrared spectra of xerogels showed peaks at around 1285 cm-1 and 1700 cm-1 assigned to O-NO2 and C-O bond representing PETN. Small angle x-ray scattering measurements on xerogels indicated that PETN entered in the pores of silica matrix. Transmission electron microscopy revealed that cystalline PETN    with particle size of around 15 nm dispersed in silica xerogel. The specific surface area for the PETN-SiO2 (90:10) xerogels was found to be 75 m2/g.Defence Science Journal, 2011, 61(6), pp.534-539, DOI:http://dx.doi.org/10.14429/dsj.61.59
