Ultra-high vacuum (often spelled ultrahigh in American English, UHV) is the vacuum regime characterised by pressures lower than about 1 × 10 −6 pascals (1.0 × 10 −8 mbar; 7.5 × 10 −9 Torr). UHV conditions are created by pumping the gas out of a UHV chamber.
The langmuir (symbol: L) is a unit of exposure (or dosage) to a surface (e.g. of a crystal) and is used in ultra-high vacuum (UHV) surface physics to study the adsorption of gases. It is a practical unit, and is not dimensionally homogeneous, and so is used only in this field. It is named after American physicist Irving Langmuir.
An entity–attribute–value model (EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc—property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design. The use-case targets applications which offer a large ...

The UHV Jaguars (also known as Jaguars, Jags, Houston–Victoria, or UHV) are the athletic teams that represent of the University of Houston–Victoria, located in Victoria, Texas, in intercollegiate sports as a member of the National Association of Intercollegiate Athletics (NAIA), primarily competing in the Red River Athletic Conference (RRAC) since the 2015–16 academic year.
The operational upheaval at Honeywell comes amid pressure from activist investor Elliott Management, which has a stake of about $5 billion. The firm disclosed its investment in November.
