The main objective of this thesis is the identification of mechanisms controlling the occurrence and the evolution of mountain permafrost in peripheral areas, i.e. where the presence of permafrost is strongly discontinuous, isolated, or even uncertain.

Son importance n’en est cependant pas moindre. Au niveau de l’entreprise, les taux de change représentent un facteur essentiel de la stratégie d’internationalisation. Leur influence sur le...
