Background: Consciousness-altering anesthetic agents disturb connectivity between brain regions composing the resting-state consciousness networks (RSNs). The default mode network (DMn), executive control network, salience network (SALn), auditory network, sensorimotor network (SMn), and visual network sustain mentation. Ketamine modifies consciousness differently from other agents, producing psychedelic dreaming and no apparent interaction with the environment. The authors used functional magnetic resonance imaging to explore ketamine-induced changes in RSNs connectivity. Methods: Fourteen healthy volunteers received stepwise intravenous infusions of ketamine up to loss of responsiveness. Because of agitation, data from six subjects were excluded from analysis. RSNs connectivity was compared between absence of ketamine (wake state [W1]), light ketamine sedation, and ketamine-induced unresponsiveness (deep sedation [S2]). Results: Increasing the depth of ketamine sedation from W1 to S2 altered DMn and SALn connectivity and suppressed the anticorrelated activity between DMn and other brain regions. During S2, DMn connectivity, particularly between the medial prefrontal cortex and the remaining network (effect size β [95% CI]: W1 = 0.20 [0.18 to 0.22]; S2 = 0.07 [0.04 to 0.09]), and DMn anticorrelated activity (e.g., right sensory cortex: W1 = −0.07 [−0.09 to −0.04]; S2 = 0.04 [0.01 to 0.06]) were broken down. SALn connectivity was nonuniformly suppressed (e.g., left parietal operculum: W1 = 0.08 [0.06 to 0.09]; S2 = 0.05 [0.02 to 0.07]). Executive control networks, auditory network, SMn, and visual network were minimally affected. Conclusions: Ketamine induces specific changes in connectivity within and between RSNs. Breakdown of frontoparietal DMn connectivity and DMn anticorrelation and sensory and SMn connectivity preservation are common to ketamine and propofol-induced alterations of consciousness. [less ▲]

Hydrogels based on polyurethane (PU) are promising (bio-) materials because of their bio- compatibility, biodegradation and excellent mechanical properties. In this publication, polyurethane hydrogels were produced for the first time by a non-isocyanate route by solvent-free step-growth copolymerization between a CO2-sourced hydrophilic polyethy- lene glycol bi-cyclic carbonate with diamines in the presence of a cross-linker. Kinetic of poly(hydroxyurethane) (PHU) synthesis was monitored by ATR-IR and the chemical cross-linking was confirmed by rheology and gel contents measurements. Hydrogels were obtained by immersion of PHUs in water and the influence of the diamine/cross-linker ratio and the nature of diamine on the water swelling and compression properties (compression modulus, strain and stress at break) of PHU hydrogels was evaluated. Additionally, the compression properties of the hydrogels were improved by the addition of Montmorillonite as nanofiller in the PHU formulation. This work opens new application fields for CO2-sourced PHUs. [less ▲]

Le but de la présentation est de synthétiser les connaissances sur le contrôle de la dynamique du phytoplancton par les contraintes environnementales dans un site de référence méditerranéen. L’étude est réalisée en Baie de Calvi (Corse) à la station PHYTOCLY (42°34.85'N, 08°43.71'E) où des séries temporelles haute fréquence de données physiques, chimiques et biologiques sont réalisées depuis 1979. Depuis 2006, l’acquisition des données de subsurface et le traitement des échantillons, qui inclut des analyses HPLC de contenu pigmentaire du phytoplancton et des comptages de flore totale, sont réalisés grâce au soutien de la DCE. En Baie de Calvi, l’intensité de la rigueur hivernale, identifiée par deux proxys, la température de l’eau et le nombre de jours de vent fort, contrôle le réapprovisionnement en sels nutritifs des couches de surface et le développement du bloom phytoplanctonique (détails dans Goffart et al., 2015, Progress in Oceanography). Lors des années caractérisées par un hiver rigoureux (e.g. 2010), le bloom phytoplanctonique hivernal se développe pendant la période d’eau froide (eau de subsurface ≤13.5°C). Il est dominé par les diatomées et les cryptophycées, deux groupes qui montrent une préférence marquée pour les eaux froides et riches en sels nutritifs. Lorsque l’hiver est très doux (e.g. 2007), la disponibilité en sels nutritifs est réduite et le bloom ne se développe pas. Les diatomées et les cryptophycées sont absentes, et les communautés phytoplanctoniques sont dominées par les prymnesiophycées pico- et nanoplanctoniques et les cyanobactéries. Les résultats de l’étude permettent aussi : • de fixer les limites de la variabilité naturelle du phytoplancton dans un site de référence méditerranéen, • d’expliquer les variations interannuelles de biomasse et de composition phytoplanctonique, • de définir les préférences écologiques des différents groupes phytoplanctoniques, • d’établir des courbes d’évolution saisonnière des principaux groupes phytoplanctoniques qui intègrent la variabilité interannuelle liée aux variations climatiques. La connaissance acquise au cours de cette étude permet de contribuer au développement d’indices de qualité intégrant la composition du phytoplancton (e.g. indice de composition I C MEDIT) et de tester des méthodes de surveillance à grande échelle (e.g. croisement des suivis pigmentaires réalisés à haute fréquence et de l’imagerie satellitaire), contribuant ainsi à la mise en œuvre des politiques publiques (DCE, DCSMM).

Belgium has fifteen structures included in the list of large dams of the International Committee on Large Dams. Six are managed by Engie Company, the other nine are owned by the Walloon regional public authority. The Belgian legislator has never enacted specific rules for large dams. However, managers have always been concerned with this issue. They developed procedures and methods that were subject to exchanges of experience with their counterparts, in particular through the Belgian Committee on Large Dams. In this ongoing research of security, the impact of multiple failure scenarios (dam break, quick emptying …) on the people and the environment downstream of dams is a particular focal point. An impact study has been conducted for the main plants. This study is based on a deterministic numerical method. The methodology, the assumptions regarding the failure mode or emptying and the lessons learned from the analyses are presented. These results are an important step in the assessment and the management of risks. Indeed, regulations were recently enacted for the management and the coordination of any activity likely to seriously impact public safety during crisis periods. These rules apply therefore for large dams. In this context, managers have established an emergency plan for each structure. This paper provides a broad overview on the issues of the evaluation and the management of dysfunction risks of Belgian dams, as well as on approaches and collaborations initiated between the private managers and public authority.

L'holographie numérique en infrarouge lointain, utilisant un laser CO2 émettant vers 10 µm et des caméras thermiques à microbolomètres, permet la mesure de grandes déformations et de s'affranchir des perturbations environnementales plus facilement qu'en lumière visible. Nous l'appliquons dans le cas de structures spatiales subissant des cyclages thermiques en régime cryogénique sous vide, ce qui induit des déplacements de grande ampleur. Nous passerons en revue les différentes expériences effectuées au Centre Spatial de Liège et discuterons des recherches en cours, notamment pour utiliser des longueurs d'onde plus grande (ondes Terahertz) [less ▲]
