Its [B-form] characteristics features lie in its dimensions : a helical diameter of 2. 37 nm(nanometers), a rise of 0. 34 nm per base pair, and a pitch(i. e. distance taken up by a complete turn of the helix) of 3. 4 nm, this corresponding to ten base pairs per turn. 1, record 1, English, - B%2Dform%20of%20DNA

Le plus grand nombre des Gastéropodes ont une coquille dissymétrique. Géométriquement, une telle coquille est une «spirale gauche», s'opposant aux spires planes ou discoïdes du type simple mais restant dans l'espace d'une spirale logarithmique, enroulée dans un cône enveloppe. Nous nommerons ces coquilles «spires hélicoïdales». La hauteur des tours successifs, mesurée sur l'axe d'enroulement croît selon une progression géométrique. 1, record 2, French, - spire%20h%C3%A9lico%C3%AFdale

Instability which can arise when an electric current is fed through a plasma with a helical density distribution immersed in a magnetic field. This will give rise to screw-shaped ion and electron clouds which move in opposite directions along the field lines and produce a charge separation. This in turn generates transverse drift motions, electric fields and growing disturbances. 4, record 4, English, - screw%20instability

Instabilité qui peut se manifester quand un courant électrique est envoyé dans un plasma à distribution de densité hélicoïdale placé dans un champ magnétique. Ceci entraîne la formation de nuages d'ions et d'électrons de forme hélicoïdale qui se déplacent en sens opposés le long des lignes de force et produisent une séparation de charge, d'où l'apparition de dérives transversales, de champs électriques et de perturbations croissantes. Ce type de macro-instabilité se produit à grande échelle, et pour des nombres d'ondes azimutaux faibles. 2, record 4, French, - instabilit%C3%A9%20en%20h%C3%A9lice
