Between June 25 and 26, 1876, a combined force of Lakota and Northern Cheyenne led the United States 7th Cavalry in to a battle near the Little Bighorn River in what was then the eastern fringe of the Montana Territory. The engagement is well known by several names: the Battle of Greasy Grass, the Battle of Little Big Horn, and Custer's Last Stand. Perhaps the most well-known action in the Indian Wars, it absolutely was a remarkable victory for Sitting Bull and his awesome forces. They defeated a column of seven hundred men led by George Armstrong Custer; five in the Seventh's companies were annihilated and Custer himself was killed in the engagement together with two of his brothers and a brother-in-law. Known as the battle that left no white survivors, Little Big Horn has inspired more than 1,000 pieces of art, including over 40 films. Here are four of the best... Next to contact breaker, spark plug is among the most weakest part of the ignition system. It is mounted within the combustion chamber from the engine, where working conditions are- severe. During peak combustion conditions the temperature inside the combustion chamber in the modern car engine may be around 2500 ºC and the pressure about 7 Mpa. Moreover a spark plug can also be exposed to thermal and load cycling fatigue on account of sudden changes in temperature and pressure-from the high temperature of burnt gas on the relatively low temperature with the air/fuel mixture and from the ruthless during the time of explosion from the air/fuel mixture to low pressure during induction. In addition, the spark plug needs to endure high voltage, mechanical vibration along with the corrosive atmosphere of combustion gages. A modern spark plug posseses an economical life of about 10,000-16,000 km. If in a very room or building, Claustrophobia sufferers may constantly be checking for doorways and exits or standing near exits even during large rooms, and feeling fear when doors are closed. Smalls spaces like cars, planes and lifts ca also bring anxious feelings. In some cases being in these situations can bring on panic disorder, in extreme cases just going to a closed door may cause a Panic Attack.
