Functionally, the hilar valve allows water vapor to enter or exit to ensure viability, while blocking liquid water. If however, humidity levels gradually rise to a high enough level, the hilar valve remains open, allowing liquid water passage for germination. [17] Physiologically, the inner and outer epidermides have independent hilar valve ...
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
An electric multi-turn actuator on a gate valve. A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic . Organic compounds

Texas has sued a New York doctor for allegedly prescribing abortion pills to a Dallas-area woman, launching the first known legal challenge of its kind, which will test what happens when two ...
These fluids will flow throughout the gate valve with little resistance to flow and there is additionally small drops in pressure. Within the gate valve, there is a gatelike disk that moves up and down perpendicular to the path of flow and seats against two seat faces to shut off flow. The velocity of the fluid against a partly opened disk may ...
