A valve is a mechanical or electromechanical device used to control the movement of liquids, gases, powders, and more, through pipes or tubes or from tanks or other containers. In most applications, valves rely on a plate, ball, diaphragm, or some other type or mechanical barrier that can be inserted to or removed from the flow stream of the material flowing through. Some valves are strictly of the on/off variety, while others allow the user to control the flow rate of the media traveling through it. The type of material a valve is made from also plays an important role in distinguishing valves and ensuring the compatibility of the wetted parts of the valve with the fluid passing through it. Furthermore, sizing is determined by the pipe or tubing diameter, flow rate, and in pipeline valves being installed as replacements, the width between flanges.

A wing is a type of fin used to produce lift while moving through air or another type of fluid. Wings feature streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. The aerodynamic efficiency of a wing is expressed through its lift-to-drag-ratio. The lift generated by a wing at a given angle of attack can be one to two orders of magnitude larger than the total drag on the wing. If a wing produces a high lift-to-drag ratio, a significantly smaller amount of thrust is required to propel the wings through the air at sufficient lift.

Ruthenium is a chemical element from the periodic cable, existing in the form of a rare transition metal that belongs to the platinum group. Ruthenium is considered chemically inert, meaning that it does not undergo any reactions when it comes into contact with most chemicals, whether in nature or during the manufacturing process. While tarnish may not result from ruthenium being in a room temperature environment, it may be explosive from oxidation, and may be attacked by hydroxides and halogenics. Ruthenium was discovered in Kazan, Russia in 1844, and it is most often found as a part of platinum ores. Ruthenium may present use across a variety of applications ranging from benefitting chemical process catalysts to combining with platinum and palladium to manufacture electrical contacts.

Aircraft cabin air systems are key in the reduction of dust, fibers, bacteria, and other microorganisms that would otherwise be present in an aircraft fuselage. They also play an important role in the simple act of breathing itself. At 35,000 feet, a fairly average cruising altitude, air pressure is low enough that even breathing pure oxygen would not provide your body with a sufficient amount of air. For this reason, all airline cabins are pressurized and require an intricate air system to pump in breathable air for passengers and all others aboard.
