Back pain is also common with increased cell phone use, especially if you hold the phone between your neck and shoulders as you multitask. Long periods of cell phone use cause you to arch your neck and hold your body in a strange posture. This can lead to back pain, says Healthcentral.com.
A recoilless rifle (RCLR) or recoilless gun is a type of lightweight tube artillery that is designed to allow some of the propellant gases to escape out the rear of the weapon at the moment of ignition, creating forward thrust that counteracts some of the weapon's recoil.lder recoilless rifles are still used by the U.S. National Park Service and the U.S. Forest Service as a system for avalanche control. The Washington State Department of Transportation uses a 105 mm recoilless rifle for avalanche control on Interstate 90.
A revolver is a repeating firearm that has a revolving cylinder containing multiple chambers and at least one barrel for firing. The term revolver refers to a handgun, but other weapons may also have a revolving chamber. These include some models of grenade launchers, shotguns, and rifles.Though the original name was revolving gun, the short-hand revolver is universally used.ach time the user cocks the hammer, the cylinder revolves to align the next chamber and round with the hammer and barrel, which gives this type of firearm its name. In a single-action revolver, the user pulls the hammer back with his free hand or thumb; the trigger pull only releases the hammer.
