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.
The AK-47, or AK as it is officially known (Russian: Ð°Ð²ÑÐ¾Ð¼Ð°Ñ ÐºÐ°Ð»Ð°ÑÐ½Ð¸ÐºÐ¾Ð²Ð°, translit. Avtomat Kalashnikova, lit. 'Kalashnikov's Automatic Rifle'), also known as the Kalashnikov, is a selective-fire (semi-automatic and fully automatic), gas-operated 7.62Ã39 mm assault rifle, developed in the Soviet Union by Mikhail Kalashnikov. It is the originating firearm of the Kalashnikov rifle (or AK) family. Design work on the AK-47 began in the last year of World War II (1945). In 1946, the AK-47 was presented for official military trials, and in 1948, the fixed-stock version was introduced into active service with selected units of the Soviet Army.
