Late glacial to deglacial sedimentary Introduction One of the peculiar interests of paleoclimatic reconstructions in the high southern latitudes involves the understanding of ice dynamic and ice-sheet behaviour mostly sensitive to temperatures and precipitations variations (Denton and Karlen, 1973; Aniya...
Comportement du champ magnétique terrestre Introduction à l’étude Dans le premier chapitre nous avons vu que le champ magnétique terrestre s’est renversé de nombreuses fois au cours du temps. Il s’agit d’un phénomène géophysique parmi les plus spectaculaires mais qui...
Energy supply by nuclear power plants constitutes, nowadays, one of the main technologies adopted in this industrial sector. The treatment and isolation of the radioactive waste generated by activities based on nuclear energy have become fundamental concerns. In principle, more...
Le rôle prépondérant de l'océan dans le cycle global du carbone Le cycle global du carbone comprend quatre réservoirs principaux : l'atmosphère, les océans, les écosystèmes terrestres et les réserves de combustibles fossiles. La vitesse des échanges entre ces réservoirs...
Females and eggs collection Pre-breeding, pre-laying, and laying adult eider females (see below for definitions) were shot at foraging and resting sites located within 5 km from the nesting colon y (from June 11 to July 11; Total N =...
Weather files One of the main input data used for the simulation of a PV system is the weather file containing the irradiance data. For calculation time reasons, the weather files used cover no more than one year, and give...
CEBC comme méthode de prévention et de contrôle du DMA Les CEBC constituent une des techniques utilisées pour la prévention et le contrôle du DMA en climat humide. Cette technique consiste à recouvrir les rejets miniers réactifs de plusieurs couches...
Competition is often viewed as one of the main driver of interactions between trees, but this idea is being challenged with examples of cooperation or facilitation through natural root grafting (Bertness & Callaway, 1994; McIntire & Fajardo, 2014). Root grafts...
As discussed in the introduction chapter, glacierized watersheds of the subarctic host a large number of potential water sources. Glaciers, the most studied water source, play a dominant role in the watershed they belong to (Kang et al., 2009). However,...
