Climate targets in European timber-producing countries conflict with goals on forest ecosystem services and biodiversity
2023
The role of increased timber harvests in reaching climate mitigation targets for European countries will be limited if the protection of forest ecosystem services and biodiversity is to be achieved, suggests an empirical forest model driven by future scenarios to limit warming to 1.5 degrees C in 2100.The European Union (EU) set clear climate change mitigation targets to reach climate neutrality, accounting for forests and their woody biomass resources. We investigated the consequences of increased harvest demands resulting from EU climate targets. We analysed the impacts on national policy objectives for forest ecosystem services and biodiversity through empirical forest simulation and mul…
Consequences of analgesics use in early pregnancy: Results of tests on mice.
2019
International audience; Self-medication during pregnancy continues to be an issue in developing countries due topoor medical education. The most commonly used drugs are analgesics, mainlyacetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of thestudy was to establish whether there are consequences of accidental use of these two drugsduring early embryogenesis. The experimental study was performed on 30 pregnant whitemice, divided into three groups: a first group to which APAP was administered, a secondgroup to which KPF was administered, and group 3 as a control group. At delivery, the babymice were examined, and after their first parturition, they were take…
The importance of social networks in the Norwegian firewood industry
2013
Accepted version of an article from journal of Biomass and Bioenergy This study examines the relationship between social network size, innovation and firm performance among firewood producers in Norway. Moreover, it investigates how this relationship is affected both by the structure and variations in networks and by firm size and age. A questionnaire-based survey was sent to managers of firms (including one-person firms) in the firewood industry in Norway. A total of 645 usable replies were received, and the theoretical model was tested using structural equation modeling. The findings show that social network size has a positive effect on firm performance via innovation by firewood produce…
Gestion des ressources naturelles dans le Pays de Tulle : impacts paysagers et histoire du châtaignier (Castanea sativa Mill.) de l'Antiquité à la Re…
2013
Este artículo presenta los resultados paleoambientales de los primeros análisis palinolójicos y sedimentológicos llevados a cabo en el area de Tulle (Mars, Gimel-les-Cascades, Corrèze, Francia). Se basan en la comparación de distintos indicadores bióticos (polen, microfósiles no polínicos) y sedimentarios y en la realización de 9 dataciones radiocarbónicas. Esta investigación establece datos inéditos sobre las dinámicas paisajísticas desde la Antigüedad y sus factores de control tanto climáticos como antrópicos. También analiza de que manera estos cambios paisajísticos pueden significar el desarrollo de sistemas de uso diversificados de los recursos vegetales como el cultivo del castaño (Ca…
Energy and economic assessment of a small domestic wind turbine in Palermo
2016
The cost effectiveness of micro-wind technology is closely linked to the annual energy production plants, which strongly depends on the wind characteristics and on the morphological properties of the installation site. The power curve of a wind turbine, supplied by manufacturers, characterizes the theoretical energy performance that it should have at a particular site. The behavior of a wind turbine in the field is affected by the speed but also by wind direction variations. At each change of direction and speed, the turbine will try to adapt to new conditions and the phase transition negatively influences the energy production. In order to experimentally confirm what above mentioned, the a…

Effet du statut organique des sols pollués sur la dynamique et l'impact du cuivre sur les communautés microbiennes
2009
National audience; L’effet du statut organique des sols (SOS) sur l’impact du cuivre a été évalué par une approche en microcosmes et lysimètres d’un sol de vigne amendé en diverses matières organiques lors d’une expérience de terrain de long terme. Des microcosmes et des lysimètres du sol de vigne ont été contaminés à 240 mg Cu kg-1 et incubés à 23°C pendant 12 mois. La distribution et la dynamique du cuivre ont été caractérisées par fractionnement granulométrique et spéciation solide en extraction séquentielles et par spéciation liquide par mesure de concentration de cuivre échangeable total (ICP-AES), libre (électrode sélective) et biodisponible (biosensor). L’impact du cuivre sur les com…
