In this paper, we review the use of satellite-based remote sensing in combination with in situ data to inform Earth surface modelling. This involves verification and optimization methods that can handle both random and systematic errors and result in effective model imp...

A differential effective medium (DEM) model is used to predict elastic properties for a set of porous and anisotropic aggregates, comprised of mixtures of calcite and muscovite. The DEM takes into consideration an anisotropic background medium with triclinic or higher s...

The various methods of mechanical removal of weeds in relation to their biology are reviewed. Depending on the stage of growth and type of weed, i.e. the depth at which new shoots can be formed and the ability to withstand burial, implements inflict damage on weeds in d...

International audience; This contribution presents a dynamic stand growth model for Beech (Fagus sylvatica L.) forests, based on a dataset provided by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, Birmensdorf. The dataset includes 143 research...

The evaluation of deforestation by optical remote sensing remains a challenge in the humid tropical region due to high cloud cover. This paper develops a simple and reproducible method for mapping deforestation of the old-growth forest using open access software. A map ...

Adaptations xéromorphes chez des Gymnospermes du Mésozoïque. Une revue avec des implications paléoclimatiques. La cuticule des plantes s'est révélée être un proxy à haute résolution des paléo-variations de la pCO2 . Toutefois, la gamme des adaptations xéromorphes est pl...

Chapitre I : Un regard dans le rétroviseur. De l'autogestion à la réforme agraire de 1987; International audience; « Aux portes d’Alger, s’étend sur un arc de cercle de trente lieues, du Chenoua (à l’ouest), au Corso (à l’est), une plaine qui sépare le Sahel de l’Atlas....

International audience; Cette étude porte sur l'évaluation de la pollution de lixiviats produits par l'ancienne décharge de la ville de Fès. Le diagnostic de lixiviats a montré une forte pollution organique difficilement biodégradable qui évolue au cours du temps. En ef...

[1] This paper extends a previous study of the harmonic (or AC) flow of a compressible fluid through a single, elastic, thick-wall pipe. The model previously developed is used to investigate propagation of pore-scale Biot slow waves through heterogeneous one-, two- and ...
