NS as an abbreviation can mean:
Kingdom of Loathing (abbreviated KoL) is a browser-based, multiplayer role-playing game designed and operated by Asymmetric Publications, including creator Zack "Jick" Johnson and writer Josh "Mr Skullhead" Nite. The game was released in 2003. Because content is added frequently, the game is considered unfinished and officially remains in open beta.
It uses hand-drawn stick figure graphics and writing characterized by surreal humor, word play, parody and references to popular culture. In KoL, a player's character fights monsters for experience, and acquiring meat (the game's currency), and/or items, through a turn-based system. Players may also interact with each other through player versus player competition, participate in the in-game economy by trading goods and services, organize their characters into clans, work together to complete clan dungeons, and speak to each other in many different chat channels.
The game is also particularly notable for managing to be financially successful purely from donations and the purchase of merchandise rather than from advertising or subscription fees, which are used by many online games. In 2008, the game had between 100,000 and 150,000 regular players. These players form an active community which frequently organizes fan meet-ups and runs an internet radio station. The game has been generally well received by critics. In 2012, Mr. Card Game, a tabletop game based on Kingdom of Loathing, was launched on Kickstarter.
The NS-23 was a 23 mm (0.91 in) aircraft cannon designed by A. E. Nudelman, A. Suranov, G. Zhirnykh, V. Nemenov, S. Lunin, and M. Bundin during World War II as a replacement for the Volkov-Yartsev VYa-23 cannon. It entered service in 1944. The NS-23 round was derived from the 14.5×114mm anti-tank round by necking it out to 23 mm.
A synchronized version, designated NS-23S (S for synchronized), was used for fixed installations firing through the propeller disc.
Applications of the NS-23 included the Antonov An-2, Ilyushin Il-10, Ilyushin Il-22, Lavochkin La-9, La-15, MiG-9, Yak-9UT, Yak-15, Yak-17, and Yak-23. Some early MiG-15s also were equipped the NS-23.
The NS-23 was replaced in service by the Nudelman-Rikhter NR-23 around 1949.
