Location Optimization of a Hydraulic Turbine for Koudiet Acerdoune Water Treatment Plants

open access: yesJournal of Materials and Engineering Structures, 2022
This study aims to recover the residual energy of the water in the water treatment plant using turbines instead of wasting energy in the dissipator as it is currently done by means of load- breaker valves.

Provisioning services decline for both people and Critically Endangered wildlife in a rainforest transformation landscape

open access: yesPeople and Nature, Volume 6, Issue 2, Page 627-645, April 2024.
Abstract The loss and degradation of forests and other ecosystems worldwide threaten both global biodiversity and the livelihoods of people who use natural resources. Understanding how natural resource use impacts landscape provisioning services for both people and wildlife is thus critical for designing comprehensive resource management strategies. We

Proton Exchange Membrane Fuel Cell With Enhanced Durability Using Fluorinated Carbon As Electrocatalyst

open access: yesE3S Web of Conferences, 2017
This study evaluates the fluorination of a carbon aerogel and its effects on the durability of the resulting electrocatalyst for Proton Exchange Membrane Fuel Cell (PEMFC). Fluorine has been introduced before or after platinum deposition.

Historical tree phenology data reveal the seasonal rhythms of the Congo Basin rainforest

open access: yesPlant-Environment Interactions, Volume 5, Issue 2, April 2024.
Ground‐based long‐term (1937–1956) phenological observations of tropical tree species in the central Congo Basin are recovered and allow for the analysis of species‐specific phenological patterns. The onset of leaf phenophases in deciduous species was triggered by drought and light availability for a subset of species and showed a species‐specific ...

Agricultural Land‐Use Increases Carbon Yields in Lowland Streams of the Congo Basin

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 3, March 2024.
Abstract As the dominant mode of deforestation in the Congo Basin, shifting agriculture is expected to increase with the projected four‐fold population growth for the region by 2,100. To assess how this land‐use change will affect the export of carbon (C) to rivers in a typical lowland forest ecosystem, we studied paired watersheds near Kisangani ...

Un scénario bas carbone "acceptable" pour la France: Élaboration participative et analyse macroéconomique [PDF]

open access: yes, 2012
The implementation of climate policies is often hindered by a lack of acceptability as well as the lack of long-term vision of stakeholders. Mitigation scenarios exercises allow the debate; however the scenario design process lacks transparency and ...

Insectivorous bats alter their flight and feeding behaviour at ground‐mounted solar farms

open access: yesJournal of Applied Ecology, Volume 61, Issue 2, Page 328-339, February 2024.
The negative effects of solar farms on bat flight and feeding behaviour should be considered when solar energy projects are planned. Research is needed to understand the mechanisms underlying the effects; for example, shading underneath solar panels may reduce plant biomass and therefore insect prey availability.
