Composant semi-conducteurvignette|Aperçu de quelques dispositifs semi-conducteurs encapsulés Un composant semi-conducteur est un composant électronique dont le fonctionnement repose sur les propriétés électroniques d'un matériau semi-conducteur (principalement le silicium, le germanium et l'arséniure de gallium, ainsi que des semi-conducteurs organiques). Sa conductivité se situe entre les conducteurs et les isolants. Les composants semi-conducteurs ont remplacé les tubes à vide dans la plupart des applications.
Direct manipulation interfaceIn computer science, human–computer interaction, and interaction design, direct manipulation is an approach to interfaces which involves continuous representation of objects of interest together with rapid, reversible, and incremental actions and feedback. As opposed to other interaction styles, for example, the command language, the intention of direct manipulation is to allow a user to manipulate objects presented to them, using actions that correspond at least loosely to manipulation of physical objects.
Bodywork (alternative medicine)In alternative medicine, bodywork is any therapeutic or personal development technique that involves working with the human body in a form involving manipulative therapy, breath work, or energy medicine. Bodywork techniques also aim to assess or improve posture, promote awareness of the "bodymind connection" which is an approach that sees the human body and mind as a single integrated unit, or to manipulate the electromagnetic field alleged to surround the human body and affect health.
