Emission (Briefmarken): Als Emission (von lateinisch: emittere - aussenden) bezeichnet der Philatelist die Ausgabe von Briefmarken oder einer Briefmarkenserie. Die Begriff dient sowohl für die Beschreibung des Ausgabezeitraums als auch für die Ausgabe selbst. (Briefmarken) [100%] 2024-01-19
Emulsion: Emulsions are tiny liquid droplets or particles suspended in a liquid. Emulsions are usually thick in texture and satiny in appearance. [75%] 2023-12-02 [Colloidal Chemistry] [Chemistry]...
Emulsion: An emulsion is a mixture of two immiscible (unblendable) substances. One substance, called the "dispersed phase," is dispersed in the other, known as the "continuous phase." Examples of emulsions include butter, margarine, espresso, mayonnaise, the photosensitive side of photographic film ... [75%] 2023-02-04
Elision: Elision is a term in epic poetry relating to the dactylic hexameter. In Latin, it means "knocking out", and is characterized by the practice of omitting certain syllables during scansion. [71%] 2023-12-02
Elision (French): In French, elision (élision) is the suppression of a final unstressed vowel (usually /ə/) immediately before another word beginning with a vowel or a silent ⟨h⟩. The term also refers to the orthographic convention by which the deletion of a vowel ... (French) [71%] 2023-12-02 [French language] [Silent letters]...
Nepal eMission: Nepal eMission is a software from Nepal Software, Borgarnes, Iceland, used to record lectures and seminars. The software is primary made for educators in all levels. (Software) [70%] 2023-11-29 [Screencasting software] [Podcasting software]...
Emission theory (vision): Emission theory or extramission theory (variants: extromission) or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory (or intromissionism), which is that visual perception comes ... (Vision) [70%] 2023-12-15 [Obsolete theories in physics] [Visual perception]...
Emission standard: Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes.

Stimulated emission: Stimulated emission is the process by which an incoming photon of a specific frequency can interact with an excited atomic electron (or other excited molecular state), causing it to drop to a lower energy level. The liberated energy transfers to ... (Physics) [70%] 2022-02-19 [Electromagnetic radiation] [Physical phenomena]...
Secondary emission: In particle physics, secondary emission is a phenomenon where primary incident particles of sufficient energy, when hitting a surface or passing through some material, induce the emission of secondary particles. The term often refers to the emission of electrons when ... (Physics) [70%] 2023-11-17 [Condensed matter physics] [Vacuum tubes]...
Spontaneous emission: Spontaneous emission is the process in which a quantum mechanical system (such as a molecule, an atom or a subatomic particle) transits from an excited energy state to a lower energy state (e.g., its ground state) and emits a ...

Nocturnal emission: Template:Otheruses4 A nocturnal emission is an ejaculation of semen experienced by a male during sleep. It is also called a "wet dream", an involuntary orgasm, or simply an orgasm during sleep. [70%] 2023-12-18 [Orgasm] [Sleep physiology]...
Electron emission: In physics, electron emission is the ejection of an electron from the surface of matter, or, in beta decay (β− decay), where a beta particle (a fast energetic electron or positron) is emitted from an atomic nucleus transforming the original nuclide ...
