investigators? The individual responsible for the crime will not be at the crime site when the crime is discovered. Forensic scientists have to rely on the evidence at the scene to piece together who might have committed the crime. Also fires and explosion can cause a great deal of damage to the crime scene. The evidence traditionally found at other crime scenes is likely to be destroyed or damaged at these crime scenes‚ making it necessary for forensic scientists to focus on other types of evidence

nitrate salts‚ sulfur and charcoal‚ now known as black powder. Gunpowder which is a low explosive‚ exhibits deflagration‚ or rapid burning‚ rather than detonation‚ the reaction exhibited by high explosives. While‚ perhaps counterintuitively‚ their explosions are started by chemical explosives‚ nuclear weapons produce far greater force by totally different mechanisms. Especially in the military‚ discussions often focus on "explosives and demolitions". The field of demolition‚ which also applies to

articles: Nuclear explosion and Effects of nuclear explosions In addition to stellar nuclear explosions‚ a man-made nuclear weapon is a type of explosive weapon that derives its destructive force from nuclear fission or from a combination of fission and fusion. As a result‚ even a nuclear weapon with a small yield is significantly more powerful than the largest conventional explosives available‚ with a single weapon capable of completely destroying an entire city. Properties of explosions[edit] Force[edit]

BOOM! ARGHH! All of a sudden explosions were going off everywhere around us. It sounded like a New Years Eve firework show at Sydney Harbour Bridge I had once been to. One massive explosion after another flying through the air‚ exploding with the biggest flash of light then an enormous bang. By now the adrenaline had kicked in and we were sprinting for our guns. Already there was blood spilt all over the ground‚ even my ears were ringing from the force of the explosions. This had all happened in less

WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

Now it was a scene straight out of hell with fire and explosions of destruction‚ a place where the cries of agonized men would be forever inplanted into the few survivers minds to haunt there darkest nightmares. The waves crashed against the shore furiously‚ washing up the tin prison cells that would bring thousands of young‚ tough‚ often inexperienced men to their deaths. BOOM! A shell landed on one of the boats‚ a direct hit; huge explosions of fuel‚ metal and torn limbs washed over into the sea
