The economic viability and energy use of vertical farms strongly depend on the efficiency of the use of light. Increasing far-red radiation (FR, 700–800 nm) relative to photosynthetically active radiation (PAR, 400–700 nm) may induce shade avoidance responses including stem elongation and leaf expansion, which would benefit light interception, and ...
Depuis les années 1960, l'aide aux pays du Sud (pays en développement) a connu des changements majeurs tant dans les institutions (passage au multilatéralisme p.ex.) que dans les modalités d'intervention (ultralibéralisme et participation sociale p.ex.). Malgré cette capacité d'adaptation, le constat est accablant : les pays du Sud les plus dévelop...
Megathrust ruptures and the ensuing postseismic deformation cause stress changes that may induce seismicity on upper plate crustal faults far from the coseismic rupture area. In this study, we analyze seismic swarms that occurred in the north Ecuador area of Esmeraldas, beginning two months after the 2016 M-w 7.8 Pedernales, Ecuador megathrust eart...
Background In endemic areas, children develop slowly and naturally anti-Plasmodium antibodies and become semi-immune. Seasonal Malaria Chemoprevention (SMC) with sulfadoxine-pyrimethamine + amodiaquine (SPAQ) is a new strategy to reduce malaria morbidity in West African young children. However, SMC may impact on the natural acquisition of anti-Plas...
Anthropogenic pressure in the high altitude lakes such as Titicaca and Uru (Bolivia) may favor the production of methylmercury (MeHg) known to accumulate in trophic chains. Periphyton associated with emerged aquatic plants (totoras) from the lake shores accumulates and demethylates MeHg providing a potential cost-effective water treatment technique...
Maternal mortality occurs mostly in contexts of poverty and health system collapse. Mali has a very high maternal mortality rate and this extremely high mortality rate is due in part to longstanding constraints in maternal health services. The central region has been particularly affected by the humanitarian crisis in recent years, and maternal hea...

L'enquête Parcours réalisée en 2012-2013 dans des établissements de santé en Île-de-France permet d'étudier les violences sexuelles que les femmes immigrées originaires d'Afrique subsaharienne ont subies après leur migration et d'examiner le contexte social de leur survenue. L'insécurité résidentielle et administrative accroît ces violences sexuell...
In West Africa, as in many other estuaries, enormous volumes of marine water are entering the continent. Fresh water discharge is very low, and it is commonly strongly linked to rainfall level. Some of these estuaries are inverse estuaries. During the Great Sahelian Drought (1968-1993), their hyperhaline feature was exacerbated. This paper aims to ...
