A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.
The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow in one direction, but is pushed open by flow in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction. Modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems.
Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on / off and pressure control to dish and clothes washers and taps in the home. Even aerosols have a tiny valve built in. Valves are also used in the military and transport sectors.
Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.
They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.
They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unixoperating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows, and OS/2 also have included them as a feature, although with somewhat different syntax, usage and standard variable names.
Details
In all Unix and Unix-like systems, each process has its own separate set of environment variables. By default, when a process is created, it inherits a duplicate environment of its parent process, except for explicit changes made by the parent when it creates the child. At the API level, these changes must be done between running fork and exec. Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. All Unixoperating system flavors, DOS, and Windows have environment variables; however, they do not all use the same variable names. A running program can access the values of environment variables for configuration purposes.
In deliberative bodies a second to a proposed motion is an indication that there is at least one person besides the mover that is interested in seeing the motion come before the meeting. It does not necessarily indicate that the seconder favors the motion.
Purpose
The purpose of requiring a second is to prevent time being wasted by the assembly's having to dispose of a motion that only one person wants to see introduced. Hearing a second to a motion is guidance to the chair that he should state the question on the motion, thereby placing it before the assembly. It does not necessarily indicate that the seconder favors the motion.
Procedure
The seconder may state "I second the motion" or "second" without first being recognized by the chair. He may remain seated but in larger assemblies, especially in those where nonmembers may be seated in the hall, the seconder should stand. After hearing a second, the chair then states the question and the motion is placed before the assembly for discussion.
Like the second, the interval of a ninth is classified as a dissonance in common practicetonality. Since a ninth is an octave larger than a second, its sonority level is considered less dense.
Major ninth
A major ninth is a compound musical interval spanning 14 semitones, or an octave plus 2 semitones. If transposed into a single octave, it becomes a major second or minor seventh. The major ninth is somewhat dissonant in sound.
When baritone/euphonium or trombone parts are written in bass clef or tenor clef they sound as written.
Minor ninth
A minor ninth (m9 or -9) is a compound musical interval spanning 13 semitones, or 1 semitone above an octave (thus it is enharmonically equivalent to an augmented octave). If transposed into a single octave, it becomes a minor second or major seventh. The minor ninth is rather dissonant in sound, and in European classical music, often appears as a suspension. Béla Bartók wrote a study in minor 9ths for piano. The fourth movement (an intermezzo) of Robert Schumann's Faschingsschwank aus Wien, is a constructed to feature prominent notes of the melody a minor ninth above the accompaniment:
The Day Utility was an automobile manufactured in Detroit, Michigan by the Day Automobile Company from 1911-14. The Day used a four-cylinder, 30 horsepower (22kW) engine and shaft drive. Removal of the rear seat and doors allowed the car to be converted from a five-seater touring car to a light truck in one minute. As a truck, the Day was able to carry up to 1,000lb (450kg) in a 36-inch (910mm) by 96-inch (2,400mm) cargo space. The rear seat could be lifted away by triggering two spring locks. The Day had an advertised price of $950US.

Over the years, Valve has solidified itself as one of the pillars of modern esports and video games.
What started off as a game development operation, spearheaded by two former Microsoft employees, has grown into an immense conglomerate of games, esports tournaments, and digital content sales.
And yet despite all this, not much is known about the company.
But what has remained crystal clear throughout the years is that Valve is one of the most important, and lucrative, gaming companies in the world. This is its story.

An Inside Look at Valve HQ
I had a chance to visit Valve's new office in Washington recently. This isn't a video strictly about VR, but with Valve being instrumental to VR's development coupled with the fact that they're an award winning developer that have made some of the best games on the planet, I figured you might be interested in a tour.
