Tzu or TZU may refer to the following:
Ci (tzu; simplified Chinese: 词; traditional Chinese: 詞; pinyin: cí; Wade–Giles: tz'u2, and, interchangeably –– to a point –– with 辭/辞) are a poetic form, a type of lyric poetry, done in the tradition of Classical Chinese poetry. Ci use a set of poetic meters derived from a base set of certain patterns, in fixed-rhythm, fixed-tone, and variable line-length formal types, or model examples: the rhythmic and tonal pattern of the ci are based upon certain, definitive musical song tunes. They are also known as Changduanju (長短句/长短句, "lines of irregular lengths") and Shiyu (詩餘/诗馀, "that which is beside poetry").
Typically the number of characters in each line and the arrangement of tones were determined by one of around 800 set patterns, each associated with a particular title, called cípái 詞牌. Originally they were written to be sung to a tune of that title, with set rhythm, rhyme, and tempo. Therefore, the title may have nothing to do with its contents, and it is common for several ci to share the same title, having little or nothing to do with the topics of those poems, but rather refers to their shared rhythmic and tonal patterns. Some ci would have a "subtitle" (or a commentary, sometimes as long as a paragraph) indicating the contents. Sometimes, for the sake of clarity, a ci is listed under its title plus its first line.
The Shang dynasty (Chinese: 商朝; pinyin: Shāng cháo) or Yin dynasty (Chinese: 殷代; pinyin: Yīn dài), according to traditional historiography, ruled in the Yellow River valley in the second millennium BC, succeeding the Xia dynasty and followed by the Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Records of the Grand Historian. According to the traditional chronology based upon calculations made approximately 2,000 years ago by Liu Xin, the Shang ruled from 1766 to 1122 BC, but according to the chronology based upon the "current text" of Bamboo Annals, they ruled from 1558 to 1046 BC. The Xia–Shang–Zhou Chronology Project dated them from c. 1600 to 1046 BC.
Archaeological work at the Ruins of Yin (near modern-day Anyang), which has been identified as the last Shang capital, uncovered eleven major Yin royal tombs and the foundations of palaces and ritual sites, containing weapons of war and remains from both animal and human sacrifices. Tens of thousands of bronze, jade, stone, bone, and ceramic artifacts have been obtained.
Recoil (often called knockback, kickback or simply kick) is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gases (ejecta), according to Newton's third law. In most small arms, the momentum is transferred to the ground through the body of the shooter; while in heavier guns such as mounted machine guns or cannons, the momentum is transferred to the ground through its mount. In order to bring the gun to a halt, a forward counter-recoil force must be applied to the gun over a period of time. Generally, the counter-recoil force is smaller than the recoil force, and is applied over a time period that is longer than the time that the recoil force is being applied (i.e. the time during which the ejecta are still in the barrel of the gun). This imbalance of forces causes the gun to move backward until it is motionless.
A change in momentum results in a force, which according to Newton's second law is equal to the time derivative of the momentum of the gun. The momentum is equal to the mass of the gun multiplied by its velocity. This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc...) from the gun. If the mass and velocity of the ejecta are known, it is possible to calculate a gun’s momentum and thus the energy. In practice, it is often simpler to derive the gun’s energy directly with a reading from a ballistic pendulum or ballistic chronograph.
The third season of CSI: Miami premiered on CBS on September 20, 2004. The season finale aired on May 23, 2005. The series stars David Caruso and Emily Procter.
Entering their third season, the Miami CSIs continue to work to rid the streets of crime using state of the art scientific techniques and back-to-basics police work. The team suffers a personal loss this season as Tim Speedle is gunned down while investigating a murder/kidnapping. Horatio hires Ryan Wolfe, a patrol officer with Obsessive Compulsive tendencies to round out their investigative squad. Facing their most explosive season yet, the team investigate piracy, car-jacking, gun-play, homicides involving snakes, and a tsunami.
Rory Cochrane left the series after the season premiere. Jonathan Togo joined the show and was promoted to series regular. Rex Linn became a new recurring cast member.
Recoil is a 1998 action/thriller film written by Richard Preston, Jr., produced by Richard Pepin and Joseph Merhi, directed by Art Camacho and starring Gary Daniels, Gregory A. McKinney, and Robin Curtis.
When a Los Angeles Police Department officers kill a young bank robber after a brutal bank heist, the slain criminal's father, mob boss Vincent Sloan, unleashes a blood bath on the police force. One by one, Detective Ray Morgan's partners are gunned down, but when his family is murdered, Morgan has nothing left to live for - except revenge. Becoming an unstoppable one man army, Morgan goes on the ultimate hunt for justice. At the end, Morgan gets his revenge. He kills Sloan with an exploding barrel blown at Sloan's radius.
