Modeling the evolution of the Guadalquivir foreland basin (southern Spain) [PDF]

open access: yesTectonics, 2002
Previous quantitative studies dealing with the origin of foreland basins have focused primarily either on the rheological basis of the lithosphere mechanical response or on the relationship between orogenic loading and sediment geometry. To link the evolution of the Guadalquivir foreland basin (South Iberia) with the thermomechanical stratification of ...

Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC-HRMS and Metabolomics Approach. [PDF]

open access: yesJ Appl Toxicol
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in
