Late glacial to deglacial sedimentary

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

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...

Contributions de l’endommagement radoucissant à la zone de rupture autour des tunnels

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 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...

Relative contribution of endogenous and exogenous sources to egg formation

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 =...

Site characteristics and consumption file

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...

Utilisation des matériaux géologiques issus des opérations minières dans les recouvrements

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...

Natural root grafting in hybrid poplar clones

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...

Water Sources in Subarctic Glacierized Watersheds

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,...

Kinetic analysis of anode baking

The green anodes are baked in the baking furnace with a certain heating rate up to about 1100-1200 °C. During baking, a part of binder pitch volatilizes, and the rest carbonizes forming a link between the dry aggregate particles (petroleum...
