MATRIX BAND [6 records]

Record 1 2015-04-17

English

Subject field(s)
  • Dentistry
CONT

A wooden wedge must be trimmed to fit anatomically with the triangle formed by the matrix band, the adjacent proximal surface and the gingival tissue... Moistening the wooden wedge by submersing it in water permits easier placement and tends to better secure its position.

French

Domaine(s)
  • Dentisterie
CONT

[...] les matrices individuelles et le séparateur McKean nécessitent l'usage d'un coin de bois pour assurer le contact intime. Nous utilisons deux types de coins de bois [...] Le vieux procédé qui consiste à les mouiller d'une teinture résineuse avant de les insérer, pour leur éviter tout déplacement ultérieur n'est pas à dédaigner [...]

Record 2 2013-10-01

English

Subject field(s)
  • Molecular Biology
CONT

Analysis of Molecular Variance(AMOVA) is a method for studying molecular variation within a species. Electrophoresis, one of the most widely used methods for studying the structure of DNA, produces data of the form of 0s and 1s where 1 denotes the presence of a band and zero its absence, e. g. Sample Band A 0101... B 1000... C 0110... AMOVA works on such data to create a distance matrix between samples in order to measure the genetic structure of a population. In statistical terms, AMOVA is a testing procedure based on permutational analysis and involves few assumptions.

French

Domaine(s)
  • Biologie moléculaire
CONT

L'analyse de la variance moléculaire et une analyse des groupements par la méthode des mesures pairées non pondérées ont servi à examiner la structure de la population et à fractionner la variance génétique.
