hypoxia in the highly turbid Gironde estuary, applying a 3D model coupling hydrodynamics, sediment transport and biogeochemical processes Estuaries are increasingly degraded due to coastal urban development, and prone to hypoxia problems. The macro-tidal Gironde estuary is characterized by the...
A relaxation method for two-phase flow models with hydrodynamic closure law Abstract The present paper is devoted to the numerical approximation of the solutions of a system of conservation laws arising in the modeling of two-phase flows in oil and...
Hypoxia in the highly turbid Gironde estuary, applying a 3D model Study area The Gironde Estuary is located in Southwest France on the Atlantic Coast, near the city of Bordeaux. It is formed by the confluence of the Garonne River...
Réactivités hydrologique et thermique de l’interface nappe-rivière pour des cours d’eau amont Introduction Understanding of the stream-aquifer interface functioning is of prime importance for the assessment of the stream ecological state and the associated biogeochemical processes (Stanford and Ward, 1988;...
Modeling anaerobic bioreactor landfills in methanogenic phase Introduction Biodegradation of municipal solid waste (MSW) in landfills is a complex and variable process Landfills develop distinctive microbial ecosystems during different decomposition phases. Waste decomposition phases ranging in number from three to...
Structure de l’écosystème planctonique : apport des données à haut débit de séquençage et d’imagerie
Structure de l’écosystème planctonique : apport des données à haut débit de séquençage et d’imagerie Structure globale de l’écosystème planctonique Préambule Dans l’introduction, la complexité des écosystèmes a été présentée. Ces écosystèmes sont composés de très nombreuses entités en interaction,...
Optimisation d’hétérostructures à multipuits quantiques InGaN sur sous-couche InGaN pour diodes électroluminescentes EPITAXIAL GROWTH AND CHARACTERIZATION TECHNIQUES Epitaxial Growth: Metal Organic Vapour Phase Epitaxy (MOVPE) MOVPE is a crystal-growth technology that allows the growth of layers of high quality semiconductor...
Télécharger le fichier original (Mémoire de fin d'études) Origine de l’étude La biologie moléculaire de laboratoire moderne, telle qu’on la connait, est difficilement envisageable sans les techniques électrophorétiques, utilisées en routine pour purifier et analyser des acides nucléiques de tailles...
