  2. Montreal Cognitive Assessment - Wikipedia

    en.wikipedia.org/wiki/Montreal_Cognitive_Assessment

    The Montreal Cognitive Assessment (MoCA) is a widely used screening assessment for detecting cognitive impairment. [1] It was created in 1996 by Ziad Nasreddine in Montreal , Quebec . It was validated in the setting of mild cognitive impairment (MCI), and has subsequently been adopted in numerous other clinical settings.

  3. Minimum obstacle clearance altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_obstacle_clearance...

    The MOCA seen on the NACO en route chart, may have been computed by adding the required obstacle clearance (ROC) to the controlling obstacle in the primary area or computed by using a TERPS chart if the controlling obstacle is located in the secondary area. This figure is then rounded to the nearest 100 foot increment, i.e. 2,049 feet becomes ...

  4. Air-operated valve - Wikipedia

    en.wikipedia.org/wiki/Air-operated_valve

    These valves have two ports that help the valves regulate the flow of air into a system. These valves often provide a simple on-off function. 3-way valves can be normally closed, normally open, and offer a universal function where gas can be diverted through a third opening to move the valve into the normally closed or normally open position.

  5. Isolation valve - Wikipedia

    en.wikipedia.org/wiki/Isolation_valve

    Isolation valves must effectively stop the passage of fluids. [4] Gate valves, ball valves and plug valves are generally considered to provide tight and effective shut-off. Globe valves and Butterfly valves may not be tight shut-off due to wear on the plug or the seat, or due to their design, and may not be appropriate to provide effective ...

  6. Blowout preventer - Wikipedia

    en.wikipedia.org/wiki/Blowout_preventer

    A blowout preventer (BOP) (pronounced B-O-P) [1] is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves.

  7. Minimum en route altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_en_route_altitude

    The MEA prescribed for a Federal airway or segment, RNAV low or high route, or other direct route applies to the entire width of the airway, segment, or route. MEAs for routes wholly contained within controlled airspace normally provide a buffer above the floor of controlled airspace consisting of at least 300 feet within transition areas and 500 feet within control areas.

  8. Valve leakage - Wikipedia

    en.wikipedia.org/wiki/Valve_leakage

    The importance of valve leakage depends on what the valve is controlling. For example, a dripping tap is less significant than a leak from a six-inch pipe carrying high-pressure radioactive steam. In the United States, the American National Standards Institute specifies six different leakage classes, with "leakage" defined in terms of the full ...
