Diuron is frequently detected in some drinking water reservoirs under the Burgundy vineyards, where organic amendments are applied. The environmental effect of these amendments on pesticide transport is ambiguous: on the one hand it could enhance their retention by increasing soil organic carbon content; on the other hand, dissolved organic matter (DOM)(More)
For the last decades, the fate of lignins in soil was analyzed mainly with cupric oxide (CuO) oxidation, which is traditionally used to quantify soil lignin content and characterize its state of degradation. This method presents limitations due to incomplete depolymerization of the lignin structure. In this study, we used a physicochemical soil lignin(More)
Purpose: To develop a model of post-surgical corneas and its application to analyze the outcomes of standard and custom myopic LASIK treatments. Methods: The optical zone (OZ), transition zone (TZ) and periphery are segmented automatically by a clustering algorithm. For each point, we compute three physical magnitudes: Gauss curvature, root-mean-square(More)
