Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. Setts , also called Belgian blocks, are often referred to as "cobbles", [ 1 ] although a sett is distinct from a cobblestone by being quarried and shaped into a regular form, while cobblestones are naturally occurring ...
A soldier examines two inverted VS-1.6 blast-resistant anti-tank landmines. Cut-away view of a VS-MK2 blast-resistant anti-personnel mine. A blast resistant mine is a landmine (intended for anti-tank or anti-personnel purposes) with a fuze which is designed to be insensitive to the shock wave from a nearby explosion.
Both vehicles incorporate a V-shaped monohull chassis that directs the force of the blast away from the occupants. [3] Buffalo is also now equipped with BAE Systems' LROD cage armor for additional protection against RPG-7 anti-tank rounds. [4] Glass armor is sufficient at 6 inches thickness. Run-flat tires are mounted on all six wheels.
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
They contend that it is improbable that penetrators could be made to burrow so deeply. With yields between 0.3 and 340 kilotons, they argue, it is unlikely the blast would be completely contained. Critics further state that the testing of new nuclear weapons would be prohibited by the proposed Comprehensive Test Ban Treaty. Although Congress ...
Samples of "ground granulated blast furnace slag" (left) and "granulated blast furnace slag" (right) Ground granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Sand-colored VS-50 mine intended for use in desert environments (shown beside a wristwatch, for scale). An anti-personnel mine or anti-personnel landmine (APL) is a form of mine designed for use against humans, as opposed to an anti-tank mine, which target vehicles. [1]
Collision resistance is desirable for several reasons. In some digital signature systems, a party attests to a document by publishing a public key signature on a hash of the document. If it is possible to produce two documents with the same hash, an attacker could get a party to attest to one, and then claim that the party had attested to the ...
