In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
An example of a low-explosive train is a rifle cartridge, which consists of a primer consisting of a small amount of primary high explosive which initiates the explosive train; an igniter which is initiated by the primer and creates a flame that ignites the propellant
An example is the British World War II Fuze, Percussion, D.A., No. 233 [2] ('direct action') The primary explosive transmits its detonation to an explosive booster within the fuze, then in turn to the main charge of the shell. As an artillery shell lands with a considerable impact, the "soft" nose may be made robust enough to be adequately safe ...
In the United States military's strategic nuclear weapon nuclear command and control (NC2) system, an Emergency Action Message (EAM) is a preformatted message that directs nuclear-capable forces [1] to execute specific Major Attack Options (MAOs) or Limited Attack Options (LAOs) in a nuclear war.
Bomb threats were used to incite fear and violence during the American Civil Rights Movement, during which leader of the movement Martin Luther King Jr. received multiple bomb threats during public addresses, [3] [4] [5] and schools forced to integrate faced strong opposition, resulting in 43 bomb threats against Central High School in Arkansas being broadcast on TV and the radio.
The Star Tribune was unable to reach representatives of Cook County Pride, which organizes the annual Pride event in Grand Marais and conducts educational outreach, social events and advocacy for ...
Bomb cyclones can occur when a cold air mass collides with a warm air mass, which is how some significant winter storms can happen. When an atmospheric river and bomb cyclone occur at the same ...
Insensitive munitions are munitions that are designed to withstand stimuli representative of severe but credible accidents. The current range of stimuli are shock (from bullets, fragments and shaped charge jets), heat (from fires or adjacent thermal events) and adjacent detonating munitions.
