Quick control NRV is generally a non return valve that has a special mechanism of closing quickly during emergency situations. It has a quicker response than a normal NRV. It is used in places of extreme caution where the downstream fluid should not by any chance return to the equipment concerned. For example it is used downstream a turbine bleed line to prevent high pressure steam from backing into the turbine.

Allelic is the same gen but non-allelic is different gene interaction.
Cyclic photophosphorylation is when the electron from the chlorophyll went through the electron transport chain and return back to the chlorophyll. Noncyclic photophosphorylation is when the electron from the chlorophyll doesn't return back but incorporated into NADPH.
It's either a "Kylie" or a "Birgan" boomerang. you may have to double check (:
non-return check valve
A non return valve is used mainly on fluid pipe, which uses gravity and the fluid to close it. A check valve is normally spring loaded to ensure a positive seal and will need a greater delta P to open. Also check valves are normally used with gas.
ON a Hansgrohe do u fit a non return valve with a diverter with hand shower

after gate valve, because when you want make maintenance for sump pump , you don't want all water in the pipe drop down sump pump - gate valve - non return valve
Bicycles with inflatable tires usually have one non-return valve for each tube/tire. Bicycles with air-sprung suspension will have one for each shock.
it allows the water to flow in only one direction.
Screw down non return valves only allow a liquid to be passed one way through it. Even when the valve is in open position valve lid is on the seat unless any liquid is pressurized from its inlet side.Any back flow will be restricted.

Can't be used with pulsating systemsClosing element may slam close causing damage and excessive wear
