Terrorism In Russia
Terrorism in Russia has a long history starting from the time of the Russian Empire. Terrorism, in the modern sense, means violence against civilians to achieve political or ideological objectives by creating extreme fear. Terrorism was an important tool used by Marxism, Marxist revolutionaries in the early 20th century to disrupt the social, political, and economic system and enable rebels to bring down the Tzarist government. Terrorist tactics, such as hostage-taking, were widely used by the Chronology of Soviet secret police agencies, Soviet secret agencies, most notably during the Red Terror and Great Purge, Great Terror campaigns, against the population of their own country, according to Karl Kautsky and other historians of Bolshevik, Bolshevism.

2010 Moscow Metro Bombings
The 2010 Moscow Metro bombings were suicide bombings carried out by two Islamic female terrorists during the morning rush hour of March 29, 2010, at two stations of the Moscow Metro ( Lubyanka and Park Kultury), with roughly 40 minutes in between. At least 40 people were killed, and over 100 injured. Russian officials called the incident "the deadliest and most sophisticated terrorist attack in the Russian capital in six years", a reference to the Avtozavodskaya and Rizhskaya bombings in 2004. At the time of the attacks, an estimated 500,000 people were commuting through Moscow's metro system. Initial investigation indicated that the bombings were perpetrated by the militant Islamist Caucasus Emirate group. On March 31, Caucasus Emirate leader Doku Umarov claimed responsibility for ordering the attacks in a video released on the internet. He also stated that such attacks in Russia would continue unless Russia grants independence to Muslim states in the North Caucasus region ...

Fragmentation (weaponry)
Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, or autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler. The correct term for these pieces is "fragmentation"; "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and sizes, and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high-velocity fragments produced by either method are the main lethal mechanisms of these weapons, rather than the heat or overpressure caused by detonation, although offensive grenades are often constructed without a frag matrix. These casing pieces are often incorrectly referred to as "shrapnel", particularly by non-military media sources. History The ...

Ball Bearings
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. History Although bearings had been developed since ancient times, the first mod ...
