Pour en isoler l'ADN, l'échantillon subit solubilisation, centrifugation et précipitation par de l'alcool. Le fragment d’ADN constitutif du transgène recherché est alors sélectivement amplifié, c'est-à-dire répliqué en de nombreux exemplaires. [...] on sépare les deux brins formant l'ADN par chauffage [...] puis on introduit dans le milieu de travail des amorces, qui sont les morceaux d’ADN encadrant le transgène. On ajoute aussi une enzyme, par exemple la Taq-polymérase, qui va, à partir des bases placées en excès dans le milieu, fabriquer le brin complémentaire d’ADN. [...] Pour séparer les transgènes des autres portions d’ADN, on pratique alors une électrophorèse, ou migration différentielle sur gel d’agarose. 7, record 1, French, - amplification%20en%20cha%C3%AEne%20par%20polym%C3%A9rase

Depolarization occurs when the polarization state changes between the transmitted and received signal. For example, changing a HH to a HV response. There are four mechanisms known to cause depolarization: a quasi-specular reflection as a result of the difference between the Fresnel reflection coefficients for a two-dimensional, smoothly undulating surface [;] a multi-scattering due to target surface roughness [;] a multiple scattering due to volume scattering [;] anisotropic properties of the targets. 3, record 2, English, - depolarization

L'onde polarisée circulairement a le désavantage, lorsque le faisceau radar pénètre la précipitation, de changer son état de polarisation de circulaire à elliptique. Ce changement d’état de polarisation, ou dépolarisation, est attribué aux effets de propagation dus à l'atténuation différentielle et au déphasage différentiel. Les mesures de radar se trouvent contaminées par ces effets et, par conséquent, rendent hasardeuse leur interprétation en termes des caractéristiques de polarisation propres à la précipitation ciblée. 2, record 2, French, - d%C3%A9polarisation
