Au travers d'Acclimaterra, le comité scientifique régional sur le changement climatique en Nouvelle Aquitaine, la région Nouvelle Aquitaine conduit depuis 2011 une démarche originale de veille sur le changement climatique régional et de prospective pour l'accompagnement à l'adaptation. La création et le fonctionnement de ce « GIEC régional » suscite une attention particulière à l'échelle territoriale et au-delà. Cette contribution propose un « making-of » de la démarche Acclimaterra.

Optimiser le renouvellement et les performances des ouvrages et réseaux qui maillent le territoire reste un enjeu majeur pour une gestion patrimoniale des infrastructures en pleine évolution. À travers l'analyse transversale de l'organisation des acteurs impliqués dans la gestion de différents types d'infrastructures – réseaux d'eau potable et d'assainissement, ouvrages hydrauliques, voiries locales et ouvrages d'art – l'article permet ici de mettre en évidence la grande diversité des configurations existantes et leurs implications en termes de gestion patrimoniale.

Apresenta-se o caso de mulher de 60 anos com doença renal policística autossômica dominante (DRPAD) que desenvolveu quadro de cefaléia e oftalmoplegia completa à direita. A TC levantou a hipótese de um aneurisma gigante do segmento intracavernoso da carótida interna direita, o que foi confirmado pela arteriografia. Realizou-se, então, tratamento endovascular por oclusão do vaso parental com molas destacáveis no segmento supraclinóideo. A paciente evoluiu com a interrupção da cefaléia e com redução parcial da ptose e da oftalmoplegia. Neste artigo, enfatiza-se a relação entre DRPAD e aneurismas intracranianos. Comenta-se a história natural dos aneurismas originados no segmento intracavernoso da artéria carótida interna e comparam-se as opções terapêuticas no manejo destas lesões.We report the case of a 60 years-old woman with autosomal dominant polycystic kidney disease (ADPKD) that presented with headache and right complete ophthalmoplegia. The CT scan raised the possibility of a giant aneurysm of the right intracavernous internal carotid artery, confirmed by angiography. The patient underwent endovascular occlusion of parent vessel with detachable coils, then she presented interruption of headache and partial recovery of ptosis and ophthalmoplegia. We emphasize the relationship between ADPKD and intracranial aneurysms. We also discuss the natural history and compare the therapeutic options for the management of giant aneurysms of the cavernous portion of the carotid artery.

The drying kinetics of carrot slices have been measured in a vacuum chamber, the experiments were carried out at various temperatures (50, 60 and 70C) under conditions of low pressures (5, 15 and 25 kPa). It was observed that the best values of diffusivity were obtained at the major temperature and low pressure for the samples pretreated by freezing. The experimental data were modeled using Fick's diffusional model in terms of moisture concentration with and without shrinkage. It is found that the calculated values of effective diffusivity for the drying process considering no shrinkage were greater than those for the drying process considering shrinkage. PRACTICAL APPLICATIONS Vacuum drying is the effective method of removal of moisture from fruits and vegetables. In this research, the experimental study and modeling on drying kinetics during the vacuum drying of carrot was studied. Also, the effect of the pretreatments, pressure and temperature on the vacuum drying kinetics was determined. A diffusion model based on Fick's second law of diffusion with and without shrinkage was used to describe the transport mechanism in the falling drying rate regions. The results from this research can be used asreference for vacuum drying and modeling kinetics drying of carrot and vegetables. [ABSTRACT FROM AUTHOR]
