Admission is the act and result of admitting (tolerating, accessing, consenting). Originating from the Latin word admissĭo , the idea of admission can be used in different areas. For example: “I am anxious: tomorrow my admission to the university will be defined” , “To enter this company you will have to pass an admission exam” , “The admission of the real amount of the debt is necessary to begin negotiations with creditors” .
It is common for the concept to be used regarding the acceptance or rejection of a person by an entity. Suppose a young man decides to pursue his university studies at a recognized and traditional institution. It is likely that the university, when analyzing your admission as a student, will carefully observe your academic career or require you to pass an exam.
In the field of law , admission is the procedure carried out to analyze the form of a judicial appeal or a lawsuit, determining whether it should move forward to be resolved or not.
The right of admission
It is known as the right of admission to the power of a company or an establishment to allow or reject a person's access to it . A dance venue (disco) can use the right of admission and prevent the entry of an individual who arrives at the door drunk and insults others.
The right of admission is not a concept that should be applied capriciously or randomly, but rather has the objective of preserving those principles that the public generally associates with the institution. In the previous example, it is clear that the management of the nightclub does not want people to associate its premises with violence and lack of responsibility, and it is for that reason that it decides to prohibit entry to the drunk individual.
Of course, in a world where equality, justice and integrity have little to do with the way people run their businesses, the reasons why a company rejects a potential client are not always as transparent as those described. higher up. The expression " the house reserves the right of admission " can be seen in many stores, usually luxury ones , to warn the public that not every individual meets its standards and, therefore, only some can enter.
The term in mechanics
If we focus on the field of mechanics , the initial stage of the process that takes place in an combustion engine when the piston sucks in a flammable mixture (also known as the fuel mixture ) is called intake. In this phase, the piston descends and the cylinder pressure decreases, generating one of two possible situations:
* In the case of compression ignition and diesel engines, what happens is that air enters the structure;
* For gasoline or Otto cycle engines, what enters is a mixture of fuel and air .
The plunger, the cylinder and the intake
This phenomenon takes place in the first of four strokes, which are intake , compression , explosion or expansion and exhaust . It is important to note that the concept of piston sometimes appears as a piston , and in this area they are synonyms: it is the piece whose movement is alternating, found within the cylinder of a machine or a pump body, which compresses or thins a fluid, or receives movement from it.
When the piston finishes its downward stroke and the cylinder is filled with mixture or air, the intake valve closes. This is the point at which the compression stroke begins.
