Redécouverte d'une faune pléistocène dans les remplissages karstiques de Tam Hang au Laos : premiers résultats.
2008
12 pages; The discovery of a Pleistocene fauna in karstic fills at TamHang in Laos: preliminary results. TamHang, located in northeastern Laos, in the Hua Pan province, is a reference site not only for its numerous archaeological and human remains, but also for its two faunal assemblages, whose composition suggests different dating in the Pleistocene. Discovered in 1934 by Jacques Fromaget, a new excavation of the site has been undertaken in 2003. During this campaign, at Tam Hang south, 575 isolated teeth of mammals were extracted from a deep layer of calcareous breccia. This assemblage corresponds to that one described by Arambourg and Fromaget [C. Arambourg, J. Fromaget, Le gisement quat…

Management et contrôle de gestion environnemental
2015
National audience; Face aux mutations environnementales (telles que les changements climatiques, l’épuisement des ressources naturelles, les pollutions marines, la perte de la biodiversité…), la préservation de l’environnement naturel est un défi pour l’organisation du XXIe siècle. Comment intégrer les enjeux environnementaux dans le management des organisations ? Comment définir et déployer une stratégie verte ? Qu’est-ce que le contrôle de gestion environnemental ? Comment mesurer la performance environnementale ? Quels sont les rôles du contrôleur de gestion et de l’auditeur dans le domaine environnemental ? Comment dialoguer avec les parties prenantes ? En répondant à ces questions, cet…
Sobre la vegetación del Orden Asplenietalia petrarchae en las montañas valencianas
1985
Se han estudiado las comunidades vegetales casmofíticas basífilas, presentes sobre los roquedos cálidos y secos, pertenecientes al orden Asplenietalia petrarchae Br.-Bl. & Mcier 1934, en el territorio de la Comunidad Valenciana y alrededores, detectándose en el mismo los siguientes sintáxones: Alianza Asplenion petrarchae Br.-Bl. & Meier 1934, con la asociación Melieo-Saturejetum fruticosae O. Bolós & Vives 1957. Alianza Teucrion buxifolii Rivas Goday 1955, con las asociaciones: Hippocrepido-Scabiosetum saxatilis (Rivas Goday 1953) O. Bolós 1957, Jasonio-Teucrietum thymifolii G. Mateo 1983, Rhamno borgiae-Teucrietum buxifolii nova y Lapiedro martinezii-Chelanthetum velleae nova. Chasmophyti…
Cannabis, cerebro y adicción
2005
El compuesto psicoactivo de la cannabis sátiva, el í-9-tetrahidrocannabinol, ejerce sus efectos sobre el sistema nervioso central a través del receptor cannabinoide CB1. La localización presináptica del receptor CB I sugiere una función de modulación de la liberación de neurotransmisores a través de la denominada señalización retrógrada. El THC actúa en el sistema de recompensa cerebral de una manera muy similar a la de otras sustancias adictivas, incluyendo tanto la capacidad de generar tolerancia y síndro me de abstinencia como la interacción con otros sistema de neurotransmisión implica dos en el fenómeno de la recompensa. El consumo de cannabis provoca, al menos de manera transitoria,…
Les légumineuses et l'azote : dix espèces de légumineuses à graines bien différentes en matière de fixation symbiotique et d'effet précédent
2020
Les bénéfices associés à l'introduction des légumineuses dans les systèmes de culture sont reconnus dans le but de tendre vers des systèmes agroécologiques plus économes en intrants azotés. Plusieurs essais menés par l'INRAE de Dijon ont pour but de comparer l'effet des légumineuses associées sur le rendement d'une culture de blé.
New records of Asteraceae for the non-native flora of Tunisia and north Africa with some nomenclatural remarks
2022
International audience; Sixteen new Asteraceae are added to the non-indigenous flora of Tunisia. Six of them (Dimorphotheca ecklonis, Gaillardia pulchella, Gazania linearis var. linearis, Guizotia abyssinica, Rudbeckia triloba and Tithonia diversifolia) are also new for the flora of North Africa. Chrysanthemum morifolium is here first reported for the Mediterranean Basin. Seven genera (Argyranthemum, Bidens, Dimorphotheca, Gaillardia, Guizotia, Rudbeckia and Tithonia) are recorded for the first time for the vascular flora of Tunisia. Most of these species escaped from gardens and pots and became casual along roadsides and/or disturbed areas after cypsela dispersion (except for Chrysanthemum…
A first search for coincident gravitational waves and high energy neutrinos using LIGO, Virgo and ANTARES data from 2007
2013
A search for high-energy neutrinos coming from the direction of the Sun has been performed using the data recorded by the ANTARES neutrino telescope during 2007 and 2008. The neutrino selection criteria have been chosen to maximize the selection of possible signals produced by the self-annihilation of weakly interacting massive particles accumulated in the centre of the Sun with respect to the atmospheric background. After data unblinding, the number of neutrinos observed towards the Sun was found to be compatible with background expectations. The 90% CL upper limits in terms of spin-dependent and spin-independent WIMP-proton cross-sections are derived and compared to predictions of two sup…
Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory
2015
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6×1019 eV by analyzing cosmic rays with energies above E ≥ 5×1018 eV arriving within an angular separation of approximately 15∘. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with …
