• Rotation

  A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated around an infinite number of imaginary lines called rotation axes (/ˈæksiːz/ AK-seez ). If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.

  Heavy Rotation Tour

  The Heavy Rotation Tour is the second headlining concert tour by American recording artist Anastacia. The tour is in support of her fourth studio album Heavy Rotation (2008). The singer played over 30 shows in Europe.

• Rotation flap

  A rotation flap is a semicircular skin flap that is rotated into the defect on a fulcrum point. Rotation flaps provide the ability to mobilize large areas of tissue with a wide vascular base for reconstruction. The flap must be adequately large, and a large base is necessary if a back-cut will be needed to lengthen the flap. If the flap is too small, the residual defect can be covered by mobilizing the surrounding tissue.

• Rotation Curation

  Rotation Curation, also #RotationCuration, is the concept of rotating the spokesperson on a broad scoped social media account. Such a scope can be a location, a country, an organization, a group, and so on. The concept is prominent on Twitter, but has also been ported to Instagram (for example la Bio au Labo ).

• Vegetal rotation

  Vegetal rotation is a morphogenetic movement that drives mesoderm internalization during gastrulation in amphibian embryos. The internalization of vegetal cells prior to gastrulation was first observed in the 1930s by Abraham Mandel Schechtman through the use of vital dye labeling experiments in Triturus torosus embryos. More recently, Winklbauer and Schürfeld (1999) described the internal movements in more detail using pregastrular explants of Xenopus laevis.

• Sector rotation

  Sector rotation is a theory of stock market trading patterns. In this context, a sector is understood to mean a group of stocks representing companies in similar lines of business. The basic premise is, that these stocks can be expected to perform similarly. Additionally, different groups of stocks which have been clustered according to the aforementioned principle will show a different performance.

• Ad rotation

  Ad rotation is the practice of showing multiple advertisements in a single location on a web page. Ads may be rotated with each new page load, within a single page load, or both. Because the ads are placed in the same location, they are typically the same format.

  Rotation of ammunition

  Rotation of ammunition is a term used with reference to guns. Projectiles intended for RML (rifled muzzle-loading ) guns were at first fitted with a number of gun-metal studs arranged around them in a spiral manner corresponding to the twist of rifling. This was defective, as it allowed, as in the old smooth-bore guns, the powder gas to escape by the clearance (called "windage") between the projectile and the bore, with a consequent loss of efficiency; it also quickly eroded the bore of the larger guns.
