V4: Sub-basin management and governance of rainwater and small reservoirs

A strong international consensus has been created regarding the need for Integrated Water Resources Management (IWRM) and what it means. The river basin is then invariably singled out as the natural unit for organizing water management. Two main reasons for these shortcomings are generally presented: a lack of political will and socio-political externalities. Calls for more reforms follow but they rarely question policy models themselves. As a consequence, they face the same shortcomings they were meant to address. This project aims at understanding the processes that govern IWRM policy-making, practices and research in the Volta Basin (Ghana and Burkina Faso)

Modalités d'interaction avec des systèmes d'aide à la décision médicale par alerte ou à la demande pour délivrer des recommandations : une étude préliminaire dans le cadre de la prise en charge de l'hypertension

Classiquement développés comme des systèmes d'alertes produisant automatiquement des thérapeutiques centrées patient, les systèmes d'aide à la décision médicale sont appréciés par les médecins utilisateurs de façon variable selon les études. Nous pensons que ce mode d'interaction n'est pertinent que dans les cas simples où le médecin pense a priori qu'il n'a pas besoin d'être aidé. Une approche " à la demande " nous semble, par ailleurs, adaptée dans les cas plus compliqués. Nous avons testé cette hypothèse avec le système ASTI développé de façon à proposer deux modes d'interaction. Dédié aux cas simples, le mode " critique ", entièrement automatique, produit des alertes lorsque la prescription médicamenteuse du médecin n'est pas conforme aux recommandations. Au contraire, le mode " guidé " est utilisé de façon volontaire par le médecin qui, au cours d'une navigation active au sein d'une base de connaissances, accède dans les cas complexes aux recommandations thérapeutiques. Un score de complexité des cas cliniques a été proposé. Une étude préliminaire a été conduite sur 15 cas cliniques et 10 généralistes qui valide notre hypothèse de travail

Detection of an atmosphere around the super-Earth 55 Cancri e

We report the analysis of two new spectroscopic observations of the super-Earth 55 Cancri e, in the near infrared, obtained with the WFC3 camera onboard the HST. 55 Cancri e orbits so close to its parent star, that temperatures much higher than 2000 K are expected on its surface. Given the brightness of 55 Cancri, the observations were obtained in scanning mode, adopting a very long scanning length and a very high scanning speed. We use our specialized pipeline to take into account systematics introduced by these observational parameters when coupled with the geometrical distortions of the instrument. We measure the transit depth per wavelength channel with an average relative uncertainty of 22 ppm per visit and find modulations that depart from a straight line model with a 6$\sigma$ confidence level. These results suggest that 55 Cancri e is surrounded by an atmosphere, which is probably hydrogen-rich. Our fully Bayesian spectral retrieval code, T-REx, has identified HCN to be the most likely molecular candidate able to explain the features at 1.42 and 1.54 $\mu$m. While additional spectroscopic observations in a broader wavelength range in the infrared will be needed to confirm the HCN detection, we discuss here the implications of such result. Our chemical model, developed with combustion specialists, indicates that relatively high mixing ratios of HCN may be caused by a high C/O ratio. This result suggests this super-Earth is a carbon-rich environment even more exotic than previously thought.Comment: 10 pages, 10 figures, 4 tables, Accepted for publication in Ap

ARES. III. Unveiling the Two Faces of KELT-7 b with HST WFC3*

We present the analysis of the hot-Jupiter KELT-7 b using transmission and emission spectroscopy from the Hubble Space Telescope, both taken with the Wide Field Camera 3. Our study uncovers a rich transmission spectrum that is consistent with a cloud-free atmosphere and suggests the presence of H_{2}O and H^{−}. In contrast, the extracted emission spectrum does not contain strong absorption features and, although it is not consistent with a simple blackbody, it can be explained by a varying temperature–pressure profile, collision induced absorption, and H^{-}. KELT-7 b had also been studied with other space-based instruments and we explore the effects of introducing these additional data sets. Further observations with Hubble, or the next generation of space-based telescopes, are needed to allow for the optical opacity source in transmission to be confirmed and for molecular features to be disentangled in emission

A humanised anti-IGF-1R monoclonal antibody (AVE1642) enhances Bortezomib-induced apoptosis in myeloma cells lacking CD45

The humanised form of an antagonistic anti-IGF-1R mAb (AVE1642) selectively inhibits the growth of CD45neg myeloma cells. AVE1642 strongly increased bortezomib-induced apoptosis, correlated with an increase of Noxa expression. These results support the therapeutic use of anti-IGF-1R/bortezomib in CD45neg Myeloma patients, particularly those with the most aggressive form, t(4,14)
