Morphology of sagitta, lapillus and asteriscus of Patagonian Genidens barbus

open access: yesMarine and Fishery Sciences, 2022
Otoliths are calcium carbonate structures, deposited as aragonite, located in the inner ear of bony fish. In recent years, they have become a useful tool for the determination of fish species, trophic content, age studies, and the identification of fish

Behavior of multi-layer permeable reactive barriers for groundwater remediation

open access: yesSoils and Foundations, 2023
This paper aims to evaluate the efficiency of a multilayer configuration of a permeable reactive barrier (PRB) made up of granular mixtures of zero valent iron (ZVI) and lapillus. The latter is a volcanic material used to disperse ZVI particles.
