Text: Not all Xbox 360 games will be supported; 104 Xbox 360 games were available for the feature's public launch on November 12, 2015 with Xbox One preview program members getting early access. Microsoft stated that publishers will only need to provide permission to the company to allow the repackaging, and they expect the list to grow significantly over time. Unlike the emulation of original Xbox games on the Xbox 360, the Xbox One does not require game modification, since it emulates an exact replica of its predecessor's environment -- both hardware and software operating systems. The downloaded game is a repackaged version of the original that identifies itself as an Xbox One title to the console. At Gamescom, Microsoft revealed it has plans to ensure ''all future Xbox 360 Games with Gold titles will be playable on Xbox One.'' On December 17, 2015 Microsoft made another sixteen Xbox 360 games compatible with Xbox One, including titles such as Halo: Reach, Fable III and Deus Ex: Human Revolution. On January 21, 2016, Microsoft made another ten Xbox 360 games compatible, including The Witcher 2: Assassins of Kings and Counter-Strike: Global Offensive. On May 13, 2016, Microsoft made Xbox 360 titles with multiple discs compatible, starting with Deus Ex: Human Revolution Director's Cut.

Text: The Electric Variable Transmission (EVT) combines a transmission with an electric motor to provide the illusion of a single CVT. In the common implementation, a gasoline engine is connected to a traditional transmission, which is in turn connected to an epicyclic gear system's planet carrier. An electric motor/generator is connected to the central ''sun'' gear, which is normally un-driven in typical epicyclic systems. Both sources of power can be fed into the transmission's output at the same time, splitting power between them. In common examples, between one-quarter and half of the engine's power can be fed into the sun gear. Depending on the implementation, the transmission in front of the epicyclic system may be greatly simplified, or eliminated completely. EVTs are capable of continuously modulating output/input speed ratios like mechanical CVTs, but offer the distinct benefit of being able to also apply power from two different sources to one output, as well as potentially reducing overall complexity dramatically.

Question: is the transmission and motor the same thing?

Text: In terms of the relational model of databases, a table can be considered a convenient representation of a relation, but the two are not strictly equivalent. For instance, an SQL table can potentially contain duplicate rows, whereas a true relation cannot contain duplicate tuples. Similarly, representation as a table implies a particular ordering to the rows and columns, whereas a relation is explicitly unordered. However, the database system does not guarantee any ordering of the rows unless an ORDER BY clause is specified in the SELECT statement that queries the table.

Question: if a table contains a primary key there can be no duplicate records in a table?
