Catalytic converters are usually used with internal combustion engines fueled by either gasoline or diesel--including lean-burn engines as well as kerosene heaters and stoves.

It is unique in all of the foreign diplomatic missions located in Nicosia in that it is officially accredited to the Turkish Republic of Northern Cyprus (TRNC), rather than the internationally recognized Republic of Cyprus (what Turkey refers to as the Greek Cypriot Administration of South Cyprus as Turkey does not recognize the Greek Cypriot Republic as a legitimate entity).

There are four physical switches on the iPad, including a home button near the display that returns the user to the main menu, and three plastic physical switches on the sides: wake/sleep and volume up/down, plus a software-controlled switch whose function has changed with software updates. Originally the switch locked the screen to its current orientation, but iOS 4.2 changed it to a mute switch, moving the rotation lock function to an onscreen menu. In the iOS 4.3 update, a setting was added to allow the user to specify whether the side switch was used for rotation lock or mute. Unlike its successors, the first-generation iPad has no cameras.

The acquired immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Acquired immunity creates immunological memory after an initial response to a specific pathogen, and leads to an enhanced response to subsequent encounters with that pathogen. This process of acquired immunity is the basis of vaccination. Like the innate system, the acquired system includes both humoral immunity components and cell-mediated immunity components.
