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.
Aim of this diploma thesis is to approach to kinetic modelling of subsurface hydrochemistry with the program code phreeqc. The reaction considered is the degradation of organic mass and its concomitant reactions. Phreeqc is a program for thermodynamical ba ...
Degradation of the biorecalcitrant pharmaceutical micropollutant ibuprofen (IBP) was carried out by means of several advanced oxidation hybrid configurations. TiO2 photocatalysis, photo-Fenton and sonolysis - all of them under solar simulated illumination ...
Metallo-β-lactamases (MβLs) constitute an increasingly serious clinical threat by giving rise to β-lactam antibiotic resistance. They accommodate in their catalytic pocket one or two zinc ions, which are responsible for the hydrolysis of β-lactams. Recent ...
Exposure of a bacterial culture to an antibiotic or other lethal stress typically results in the generation of sub-populations of live cells ("persisters") and dead cells, and, in some cases, viable but non-culturable cells. Studies aimed at understanding ...
The work presented in this thesis was carried out in the framework of two European projects: SOLWATER, and AQUACAT. The global objective of those projects, including the present work, was to set an autonomous system for drinking water production in develop ...
Phenotypic heterogeneity, defined as metastable variation in cellular parameters generated by epigenetic mechanisms, is crucial for the persistence of bacterial populations under fluctuating selective pressures. Diversity ensures that some individuals will ...
A wide variety of antibacterial compounds is rapidly oxidized by O-3 and hydroxyl radical ((OH)-O-center dot) during aqueous ozonation. Quantitative microbiological assays have been developed here or adapted from existing methods and utilized to measure th ...
A total asymmetric synthesis of the polyol subunit of the polyene macrolide antibiotic RK-397 was developed through the stereoselective functionalization of (1R,1’S,6S,6’R)-3,3’-methylenebis(cyclohept-3-ene-1,6-diol). The pathway generates a large variety ...
The Fenton and photo-Fenton mediated degradation process of Orange II was investigated in a flow photo-reactor. The degradation was monitored as a function of the wavelength of the applied light, recirculation flow rate, amount of H2O2 and the initial conc ...
The power of two! A natural product hybrid (see structure) composed of a siderophore and an antibiotic separated by a poly(ethylene glycol) linker enables the preparation of antimicrobial and cell-resistant surfaces by a simple dip-and-rinse procedure. The ...
