Bonjour

Comment dit on "souche" en anglais, contexte : souche virale, par ex pour la grippe humaine les souches ne sont pas identiques d'une année sur l'autre

Merci de vos réponses

Je epnsais aussi à ça, ou à stem. Mais tu as regardé dans le Grand Dico, Vikr ? Parce que selon les combinaisons de termes, il donne plein de trads différentes.

Je suis sûre qu'ANTHOS pourra t'en dire plus

C'est bien "strain". Par exemple, on parlait beaucoup de H5N1 strain pendant l'épisode de grippe aviaire.

C'est bien ca apparement. Voici que ce raconte Wikipedia.

The two solstices can be distinguished by different pairs of names, depending on which feature one wants to stress.

Summer solstice and winter solstice. These names can be used when one wants to explain the cause of the seasons. But as the seasons of the northern hemisphere and southern hemisphere are opposites, the summer solstice of one hemisphere is the winter solstice of the other, which makes their use ambiguous.

June solstice and December solstice. An alternative to the previous set, but without the ambiguity for which hemisphere they are intended. Still not universal, however, as not all people on Earth use a solar based calendar where the solstices occur every year in the same month (Jewish calendar for example), and also not useful for other planets (Mars for example), even though they do have seasons.

First point of Cancer and first point of Capricorn. Alternative names for the previous set. Disadvantage is that due to the precession of the equinoxes these astrological signs where these solstices are located, do not correspond any longer with the actual constellations.
Taurus solstice and Sagittarius solstice. Names to indicate in which constellations the two equinoxes are currently located. These terms are not widely used, the more so since until December 1989 the first solstice was in Gemini according to official IAU boundaries.

Northern solstice and southern solstice. Maybe the best names after all, being neutral yet completely unambiguous. But why is no one using them?

justement ce qui m'a un peu surpris ce sont les périodes prises en compte !!

Hemanta ritu starts from mid November and ends in mid January. This falls in southern solstice which is called as visarga kala or dakshinayana

là ça va, mais

Sisira ritu starts from mid January and lasts till middle of march. Sisira ritu falls in Northern solstice which is called as Aadana kaala or uttaraayana.

là pour le solstice d'été , c'est un peu tôt , non?
