Air volume regulator. Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning system.Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant or varying temperature.
The Messier catalogue: the Messier objects are a set of astronomical objects first listed by French astronomer Charles Messier in 1771.

Pumped air injection systems use a vane pump called the air pump, AIR pump, or colloquially "smog pump" turned by the engine via a belt or electric motor.The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system.
The Smithsonian Astrophysical Observatory Star Catalog is an astrometric star catalogue, created by Smithsonian Institution, a research institute.It was published by the Smithsonian Astrophysical Observatory in 1966 and contains 258,997 stars.
Newer generations of library catalog systems, typically called discovery systems (or a discovery layer), are distinguished from earlier OPACs by their use of more sophisticated search technologies, including relevancy ranking and faceted search, as well as features aimed at greater user interaction and participation with the system, including tagging and reviews.
