Microscopic scaleThe microscopic scale () is the scale of objects and events smaller than those that can easily be seen by the naked eye, requiring a lens or microscope to see them clearly. In physics, the microscopic scale is sometimes regarded as the scale between the macroscopic scale and the quantum scale. Microscopic units and measurements are used to classify and describe very small objects. One common microscopic length scale unit is the micrometre (also called a micron) (symbol: μm), which is one millionth of a metre.
Cellule de SchwannLes cellules de Schwann (ou neurolemmocytes) sont une variété de cellules gliales qui assurent principalement l'isolation myélinique des axones du système nerveux périphérique des chordés (on les classe donc parmi les « cellules gliales périphériques »). Comme les oligodendrocytes du système nerveux central, elles assurent la myélinisation — c'est-à-dire l'isolation électrique — des axones mais dans le système nerveux périphérique. Il existe néanmoins de petites différences entre ces deux types de cellules.
KataninKatanin is a microtubule-severing AAA protein. It is named after the Japanese sword called a katana. Katanin is a heterodimeric protein first discovered in sea urchins. It contains a 60 kDa ATPase subunit, encoded by KATNA1, which functions to sever microtubules. This subunit requires ATP and the presence of microtubules for activation. The second 80 kDA subunit, encoded by KATNB1, regulates the activity of the ATPase and localizes the protein to centrosomes.
MyxogastriaMyxogastria/Myxogastrea (myxogastrids, ICZN) or Myxomycetes (ICN), is a class of slime molds that contains 5 orders, 14 families, 62 genera, and 888 species. They are colloquially known as the plasmodial or acellular slime moulds. All species pass through several, very different morphologic phases, such as microscopic individual cells, slimy amorphous organisms visible with the naked eye and conspicuously shaped fruit bodies. Although they are monocellular, they can reach immense widths and weights: in extreme cases they can be up to across and weigh up to .
Niveau (jeu vidéo)vignette|250px|Première partie du premier niveau de Abuse un jeu de type run and gun. En vert le gabarit de ce qui est visible à l'écran. Un niveau (en anglais level ou stage) ou carte (en anglais map) est une étape dans un jeu vidéo. Généralement il correspond à une unité de lieu (et de temps) dans la progression. Les niveaux se distinguent par divers caractéristiques : environnement, topographie, ennemis, objectifs, difficulté Dans les jeux de plate-forme et les shoot them up, le niveau se parcourt généralement au rythme du scrolling (défilement du décor) et se termine souvent par la confrontation avec un boss.
Eccentric trainingEccentric training is a type of strength training that involves using the target muscles to control weight as it moves in a downward motion. This type of training can help build muscle, improve athletic performance, and reduce the risk of injury. An eccentric contraction is the motion of an active muscle while it is lengthening under load. Eccentric training is repetitively doing eccentric muscle contractions.
