Écran à plasma
Les écrans à plasma fonctionnent de façon similaire aux tubes d'éclairage fluorescents (improprement appelés « néons »). Ils utilisent l’électricité pour illuminer un gaz. thumb|300px|Schéma de principe Le gaz utilisé est un mélange de gaz nobles (argon 90 % et xénon 10 %). Ce mélange de gaz est inerte et inoffensif. Pour qu'il émette de la lumière on lui applique un courant électrique qui le transforme en plasma, un fluide ionisé dont les atomes ont perdu un ou plusieurs de leurs électrons et ne sont plus électriquement neutres, alors que les électrons ainsi libérés forment un nuage autour.
Primitive data type
In computer science, primitive data types are a set of basic data types from which all other data types are constructed. Specifically it often refers to the limited set of data representations in use by a particular processor, which all compiled programs must use. Most processors support a similar set of primitive data types, although the specific representations vary. More generally, "primitive data types" may refer to the standard data types built into a programming language (built-in types).
Centrifugal mechanism of acceleration
Centrifugal acceleration of astroparticles to relativistic energies might take place in rotating astrophysical objects (see also Fermi acceleration). It is strongly believed that active galactic nuclei and pulsars have rotating magnetospheres, therefore, they potentially can drive charged particles to high and ultra-high energies. It is a proposed explanation for ultra-high-energy cosmic rays (UHECRs) and extreme-energy cosmic rays (EECRs) exceeding the Greisen–Zatsepin–Kuzmin limit.
