Stromboli ou le tourisme roulette russe

Via@, 2020
Le Stromboli est l’un des volcans les plus actifs de la planète  ; il est aussi devenu, depuis à peine plus d’un demi-siècle, un haut-lieu touristique.Les récents paroxysmes éruptifs de l’été 2019 ont spectaculairement mis en valeur cette situation ...

Modélisation d’un système de stockage intégré dans un système hybride (PV / Eolien / Diesel)

Journal of Renewable Energies, 2023
Ce travail a pour but l’étude de simulation du fonctionnement physique d’un accumulateur électrochimique intégré dans un système hybride sur le site du CRAER, en utilisant le logiciel Matlab à partir de modèles mathématiques. Nous avons déterminé l’influence de différents paramètres sur le fonctionnement du système de stockage, en particulier la ...

Spatialisation et territorialisation du grand éolien en France : le gigantisme contre l’utopie ?

Bulletin de l’Association de Géographes Français, 2021
Before appearing on the public policy agenda at the turn of the century, renewable energies were initially promoted by actors proposing an alternative project for society. Deeply monopolistic, centralised and polluting, nuclear energy was then castigated

Spatial and Temporal Variations of Water Quality of Mateur Aquifer (Northeastern Tunisia): Suitability for Irrigation and Drinking Purposes

Journal of Chemistry, Volume 2018, Issue 1, 2018., 2018
The present study aims to assess the spatial and temporal variations of the hydrochemical characteristics of Mateur aquifer groundwaters, a crucial water resource in the northeast of Tunisia. The aquifer was subject to water quality deterioration due to salinization and nitrate contamination, and a new assessment of water quality was needed.

Variation in prevalence and intensity of macroparasites in moose and their interactions with winter tick load in eastern Canada

Wildlife Biology, Volume 2025, Issue 5, September 2025.
Wild animals are infected with a large diversity and abundance of parasites that can affect their behavior, growth, body condition, and ultimately their survival. Although the adverse effects of parasites and the mechanisms involved in the interactions between a host and its parasites are generally well studied, much less is known about the additive or

Le foisonnement éolien : les limites d’un mix électrique à forte proportion d’énergies renouvelables intermittentes

Comptes Rendus. Chimie, 2023
Intermittency of wind and solar productions raises the concern of finding other sources of electricity to match the consumption when an hibernal anticyclone reduces dramatically wind production.

Towards a better understanding of avian collision in wind energy facilities using automatic detection systems

Journal of Applied Ecology, Volume 62, Issue 6, Page 1437-1448, June 2025.
Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Eoldist, a Web Application for Estimating Cautionary Detection Distance of Birds by Automatic Detection Systems to Reduce Collisions With Wind Turbines

Wind Energy, Volume 28, Issue 2, February 2025.
ABSTRACT The installation of automatic detection systems (ADSs) on operating wind energy facilities is a mitigation measure to reduce bird collisions. The effectiveness of an ADS depends on a combination of parameters, including the detection distance of the bird, its flight speed, and the time to complete the chosen action (e.g., turbine shutdown). We
