Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Field and laboratory investigations have been conducted at a former coke plant, discharging to an adjacent river, in order to assess pollutant attenuation in a contaminated alluvial aquifer. Various organic (BTEX, PAHs, mineral oils) and inorganic (As, Zn, ...
Widely used in industrial activities, chloroethenes have become common groundwater contaminants. Dehalorespiration is an anaerobic bacterial respiration coupling their sequential degradation to energy production. The interactions between the dehalorespirin ...
Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents since the beginning of the 20th century. These compounds are known to persist in the environment, exerting adverse effects. They have been considered for ...
Sustainable management of underground natural resources is more and more a worthwhile topic. In particular, worrying about groundwater protection becomes imperative. Taking into account the increase of incompatibilities between water conservation and the u ...
Groundwater managers have often to face regional degradation of the quality of the groundwater under the pressure of diffuse pollution. One of the most problematic and widespread contaminant is certainly nitrate whose concentrations are found in many aquif ...
The selective radius shift model was used to relate changes in mineral volume due to precipitation/dissolution reactions to changes in hydraulic properties affecting flow in porous media. The model accounts for (i) precipitation/dissolution taking place on ...
Mobilization of arsenic (As) in the subsurface environment can result in elevated concentrations of As in groundwater and potential human exposure and adverse health effects. Natural attenuation (i.e., sequestration) of As may, under appropriate geochemica ...
The main objective of this thesis is to improve the understanding of the position and characteristics of karst conduits within a rock massif. Such a characterisation is an important issue in civil engineering and in hydrogeology. Today in practice dissolut ...
The zone of calcified cartilage (ZCC) is critical for the normal attachment of articular cartilage to bone as well as to the biomimetic bioengineering of osteochondral tissue constructs. However, relatively few osteochondral tissue engineering approaches h ...
The concentrations of 16 trace elements were investigated and compared for the first time in the digestive and excreting tissues of two Nautilus species (Cephalopoda: Nautiloidea) from two geologically contrasted areas: (1) N. macromphalus from New Caledon ...
