Download and read online The Basics of Explosives in PDF and EPUB Explosives are used around the world for both productive purposes such as building hydroelectric dams and mining and destructive purposes, primarily by the military. Explosives are usually divided into two classes those that burn and those that detonate. Detonated explosives typically produce a shock front or shock wave that results from an exothermic chemical reaction. This chemical reaction usually results in a relatively stable compound being exposed to a concentrated source of energy such as a blasting cap or other type of detonation device. The solid explosive will phase shift to a high temperature expanding gas in approximately one-millionth of a second (a nanosecond) with pressures exceeding several million pounds per square inch. For one example we can examine 'Det Cord', also known as Primacord which is usually produced in rolled up or coiled section of cord. This cord is then unwound and when detonated will produce an explosive front along the length of the cord that travels at the speed of 5 miles per second. In other words, if you laid out 5 miles of Det cord, and detonated it, the 5 miles of cord would be explosively spent in one second. Whereas if you burned or ignited the same amount cord it could take weeks to burn to completion. This 2 volume set explains the nature of the various industrial and military explosives and also discusses some of the chemistry involved in these explosives - particularly in the 2nd volume.

Download and read online Detection of Liquid Explosives and Flammable Agents in Connection with Terrorism in PDF and EPUB The organization of an Advanced Research Workshop with the title “Detection and Disposal of Liquid Explosives and Flammable Agents in Connection with Terrorism” was motivated by international findings about activities in this field of application. This ARW followed a meeting about the “Detection of Disposal Improvised Explosives” (St. Petersburg, 2005). Both items show the logistic problems as one of the lessons, terrorists have to overcome. These problems are connected with the illegal supply and transport of explosives and fuels and as counter-measure the detection of these materials. The invention of liquid explosives goes back to the middle of the 19th century and was used for special purposes in the commercial field of application. Because of the high sensitivity of liquid explosives against mechanical shock, caused by adiabatic compression of air-bobbles producing “hot spots” as origin of initiation the commercial application was not very successful. Because of this high risk, liquid explosives are not used in military or commercial application with some exceptions. In the commercial field explosives as slurries or emulsions consisting of suitable salts (Ammoniumnitrate etc.) and water are used to a large extend because of their high insensitivity. In many cases these slurries or emulsions were unfit for terrorist actions, because of their low sensitivity, large critical diameter and using in confinement. In the military field liquid explosives are used in World War I and II as bomb-fillings.

Download and read online Explosives Arson Investigation in PDF and EPUB An uncanny calm settles on the scene. The blaze is out. A soggy, sooty mess remains. Most of us wouldn't have a clue where to begin, yet fire and explosion investigators know precisely where and how to dig in. Other books in this series show that documents, fingerprints, a stray hair, fibers, bullets, tool marks, blood spatter, SNA, cigarette butts, insects, or even a simple candy wrapper can provide clinching proof in many legal cases—but fire and bombs destroy these bits of evidence. What clues can forensic scientists possibly glean from rubble and ash? Using real-life stories as examples, Explosives & Arson Investigation explores the world of fire—and bomb-scene investigation. From first-on-the-scene priorities to collecting and documenting evidence to lab analysis and its procedures, then finally assessing motive, this book reveals basic fire characteristics, what investigators look for, how they process what they find, the meaning of specific clues, and common motives—all while highlighting various forensic careers.
Download and read online Always Faithful Always Forward in PDF and EPUB Established in 1986, the U.S. Special Operations Command was set up to bring the special operational disciplines of all branches of the military under a single, unified command to act on missions involving unconventional warfare, special reconnaissance, foreign internal defense, and direct action… The Marine Special Operations Command (“MARSOC”) is the newest component of the military’s shift toward a fully integrated Special Operations Command structure. At first, the Marines were strongly against any Marines serving under anyone other than another Marine. Then 9/11 happened. In the years following, Marine forces found themselves growing more agreeable to inter-branch operational command, finally forming the Marine Special Operations Command in 2006. Always Faithful, Always Forward follows the journey of a class of Marine candidates from their recruitment, through assessment and selection, to their qualification as Marines Special Operators. The assessment, selection, and training regimes are a combination of psychological testing and intense military training as well as being a physical and professional rite of passage. MARSOC Marines must be efficient, agile, independent, and prepared to live hard in the field. They are warriors trained in the full range of military skills, as well as teachers who can train locals to defend their communities and lead them in battle. But above all, they are Marines. Their ability to leverage their numbers by embedding with the locals and to live in remote locations has, in their short history, made them a valuable force and one with great utility in remote reaches of the world. Retired Navy Captain Dick Couch has been given unprecedented access to this new command and to the individual Marines of this exceptional special-operations unit, allowing him to chronicle the history and development of the Marine Special Operations Command and how they find, recruit, and train their special operators. INCLUDES PHOTOGRAPHS
