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.
In this study Bacillus sp. MTCC5877 was explored for the production of biosurfactant (BSs) and various carbon sources 1% (w/v), 0.5% (w/v) nitrogen sources were tested at different pH, and temperature. Yield was measured in terms of Emulsification index (E ...
This bachelor project work aims to set up a prototype measurement station in the Sorge (a small river near the EPFL) to collect some data about the water and the environmental conditions. And also make the work reproducible so that someone, somewhere else ...
The interfaces of neat water and aqueous solutions play a prominent role in many technological processes and in the environment. Examples of aqueous interfaces are ultrathin water films that cover most hydrophilic surfaces under ambient relative humidities ...
Base Mine Lake (BML) is a pit lake used to store the Fluid Fine Tailings (FFT) generated by the oil sands industry, in the Athabasca region (northern Alberta, Canada). It is well studied to try understanding its evolution over time and to determine if an e ...

The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...
Water and food are basics of human life, unfortunately climate changes and water pollution have reduced the amount of water available for human uses. In this context the study of the hydrologic cycle is becoming of growing importance in order to optimize t ...
Instantaneous longitudinal velocity fields are derived from the velocity measurements collected with the ADVP. Detailed velocity profiles are the base for the estimation of the bottom shear stress through the logarithmic law of the wall. Bottom shear stres ...
The ability to evaluate stream hydrochemistry is often constrained by the capacity to sample streamwater at an adequate frequency. While technology is no longer a limiting factor, costs and sample management can still be a barrier to high-resolution water ...
Lake Geneva (Lac Léman) is the largest freshwater body in Western Europe. It is a deep peri-alpine lake whose importance stems from being not only an essential freshwater source in the region, but also a major tourist destination, a fishery and a waterway. ...
