Experimental methods for determining a performance index of explosives are analysed: the ballistic pendulum, mortar, lead block, and according to volume soil explosion funnel. It is defined that determination emulsion (EE) involves set significant features connected with large critical diameter requiring experiments large-mass charges resulting in refusal from traditional index. Analytical calc...
"Biological terrorism is more likely than ever before and far more greatly to be feared than explosives or chemicals."
The paper begins with a general introduction and update to Fourth Generation Nuclear Weapons (FGNW), and then addresses some particularly important military aspects on which there has been only limited public discussion so far. These aspects concern the unique military characteristics of FGNWs which make them radically different from both nuclear weapons based on previous-generation nuclear-exp...
Recently, there has been a significant interest in employing Terahertz (THz) technology, spectroscopy and imaging for standoff detection applications. There are three prime motivations for this interest: (a) THz radiation can detect concealed weapons since many non-metallic, non-polar materials are transparent to THz radiation, (b) target compounds such as explosives, and bio/chemical weapons h...
In this research, the thermal stability and decomposition kinetics of pentaerythritol tetranitrate (PETN) and Pentastite explosives have been studied experimentally using non-isothermal differential thermal analysis (DTA) and thermo-gravimetric (TG) methods at heating rates of 4.0, 6.0, 8.0 and 10.0 °C/min. The kinetic parameter of activation energy (Ea) and critical ignition temperature fo...
Abstract Environmental pollution from the use of lead compounds and their adverse effects on employees, users and consumers of ammunitions is a serious problem in the military industries. Primary explosives such as lead azide and lead styphnate are essential portions of initiators and have wide consumption in military industries for producing initiators, tinder and detonators. These leaded com...
