A Pelton wheel is an impulse-type water turbine invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energy—which allowed for a very efficient turbine.

ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO). It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously distinguished between sizes. For example, at least 6 different "26 inch" sizes exist, and "27 inch" wheels have a larger diameter than American "28 inch" wheels. The Japanese standard JIS D 9421 specifies the same dimensional system, but adds details on additional rim types and also specifies additional parameters such as rim strength and details spoke holes.

The Merchanter novels are several loosely connected novels by science fiction and fantasy author C. J. Cherryh set in her Alliance-Union universe. These science fiction novels explore her merchanter subculture: the extended families that own and operate the ships that supply goods, transportation, news and trade to the various worlds and space stations in the human Earth, Alliance and Union space. The novels are related by a common setting and theme – a misfit who finds his or her proper home – rather than plot and character; none of the books is a direct sequel of another in the conventional sense.
