Achieving complete nitrification below the washout SRT with hybrid membrane aerated biofilm reactor (MABR) treating municipal wastewater

2021

This study analyzed the performances of a hybrid membrane aerated biofilm reactor (MABR) pilot plant in terms of nutrients removal of the attached growth and suspended biomass in comparison with a conventional activated sludge (CAS) system at different sludge retention time (SRT) (20−3) days. Overall, the MABR showed better performances than the CAS in terms of TSS (86% vs 79%), COD (89% vs 85%) and total nitrogen (80% vs 65%). The minimum SRT for achieving complete nitrification in the MABR was close to 3 days, corresponding to a SRT in the aerobic compartment of 1.9 days, whereas in the CAS it was equal to 8 days (aerobic SRT of 4.8 days). Nitrification rate in biofilm was on average equa…

Apprentissage implicite de régularités : Mise en évidence d'une différence d'apprentissage entre tâches motrices continues et discrètes

2005

This research is concerned with the implicit learning of regularities in continuous motor tasks (e.g., tracking tasks) and discrete tasks (e.g., Serial Reaction Time tasks). First, a reanalysis of Wulf and collaborator's studies, dealing with implicit motor learning, made it possible to highlight methodological problems and potential biases that provide alternative explanations for the apparent implicit learning obtained in their continuous tracking experiments. Indeed, by respecting a more rigorous methodology, it appears that it is quite difficult to obtain such learning in a continuous task. This led us to try to understand why it was easier to draw benefit from a repetition in a discret…

Recognition of earthquake-induced damage in the Abakainon necropolis (NE Sicily): results from geo-morphological, geophysical and numerical analyses

2017

Seismotectonic activity and slope instability are a permanent threat in the archaeological site of Abakainon and in the nearby village of Tripi in NE Sicily. In recent times, signs of an ancient earthquake have been identified in the necropolis of Abakainon which dating was ascertained to the first century AD earthquake. The site is located on a slope of Peloritani Mts. along the Tindari Fault Line and contains evidence for earthquake-induced landslide, including fallen columns and blocks, horizontal shift and counter slope tilting of the tomb basements. In this paper, we used an integrated geomorphological and geophysical analysis to constrain the landslide. The research was directed to th…
