Comme les écosystèmes dulçaquicoles, les écosystèmes marins sont soumis à une pression humaine croissante qui altère la qualité de l’eau et les communautés aquatiques. Près de 98 pourcents de l’eau de notre planète bleue est contenue dans les océans qui constituent le réceptacle final de tout ce que nous rejetons comme déchets (volontairement ou non). Moins accessible, les océans sont méconnus, souvent oubliés ou négligés et considérés comme une zone inépuisable et où tout se dilue ; actuellement encore 80% des eaux usées sont rejetées en mer sans traitement préalable, à peine 2 % des surfaces marines sont protégées. La Méditerranée est particulière à plus d’un égard, bassin de concentration, de faible surface (1% des océans) abritant pourtant plus de 10% de la biodiversité mondiale. Cette petite mer est un modèle pour les océanographes : en mesurant ce qui s’y passe, nous pouvons prédire ce que se déroulera à court ou moyen terme dans le reste des océans. Le laboratoire d’Océanologie est activement impliqué depuis une quinzaine d’années dans la mise au point d’indice de la qualité des masses d’eau côtières. Ces indices sont construits sur base des connaissances du milieu (variations naturelles), par la mesure des niveaux de contamination et des effets (observation et contamination en mésocosme) de cette pollution sur les communautés. Nous avons développé et validé des indices biologiques (PREI : Posidonia Rapid and Easy Index, ICAR Indice Caulerpa cylindracea ; espèce envahissante), de pollution (TEPI : Trace Element Pollution Index, TESVI : Trace Element Spatial Variation Index), de qualité paysagère (LIMA LIttoral MArin) … Ces indices sont utilisés actuellement dans le cadre de la DCE (Directive Cadre Eau), la DCSMM (Directive Cadre Stratégie pour le Milieu Marin) et dans des réseaux de surveillance en Méditerranée, ils sont un relais et un moyen de communication entre les scientifiques et les politiques, les gestionnaires. L’exportation et l’apprentissage de l’utilisation de ces indices sont un atout pour une gestion globale de l’eau à l’échelle de la Méditerranée. Leurs applications sur l’ensemble de la façade méditerranéenne ont, entre autre, mis en évidence l’impact positif de l’application de directives européennes en matière de gestion des eaux par rapport aux côtes de Nord de l’Afrique.

Sixteen weaned male Alpine kids (Capra hircus) were subjected to a 21-day oral daily exposure of 0.05 mg kg 1 BW. d 1 of chlordecone (CLD) and 0.30 mg kg 1 BW. d 1 of each non-dioxin-like polychlorinated biphenyls (NDL-PCBs, congeners 28, 52, 101, 138, 153 and 180). Four kids, identified as the CONTA group, were slaughtered at the end of the exposure, while the remaining animals (n ¼ 12) were fed with specific diets for an additional 21-day decontamination period before slaughtering. Kids from the DECONTA (n ¼ 4) group were fed a control diet, while those from the AC10% and PO8% group received pellets supplemented with 10% activated carbon (AC) and 8% paraffin oil (PO), respectively. CLD and NDL-PCB levels in blood, liver, peri-renal fat and muscles from different groups were analysed to compare the decontamination dynamics of the pollutants and to determine the efficiency of AC and PO to decrease the body levels of pollutants. After the decontamination period, the CLD levels considerably decreased (more than 60%) in blood, liver, muscles and fat. Concerning NDL-PCBs, the decontamination process was much lower. Overall, CLD appeared to be less retained in kids’ organism compared with NDL-PCBs, and the decontamination dynamics of these pollutants appeared to be different because of their specific physicochemical properties and lipophilicity. Furthermore, the dietary supplementation with AC or PO did not significantly affect the decontamination dynamics. [less ▲]

Surface-enhanced Raman spectroscopy (SERS) is a sensitive analytical tool used in the pharmaceutical field in recent years. SERS keeps all the advantages of classical Raman spectroscopy while being is more sensitive allowing its use for the detection and the quantification of low-dose substances contained in pharmaceutical samples. However, the analytical performance of SERS is limited due to the difficulty to implement a quantitative methodology correctly validated. Nevertheless, some studies reported the development of SERS quantitative methods especially in pharmaceutical approaches. In this context, this review presents the main concepts of the SERS technique. The different steps that need to be applied to develop a SERS quantitative method are also deeply described. The last part of the present manuscript gives a critical overview of the different SERS pharmaceutical applications that were developed for a non-exhaustive list of pharmaceutical compounds with the aim to highlights the validation criteria for each application.

Regenerative design holds great promise for a new era of sustainable and positive impact architecture, sparking considerable interest among architects, building professionals and their clients. Until now there are no green buildings with an overall positive impact on environment and health. In this regard, the professional and scientific potential of regenerative architecture can only be fully realized by the setting a design framework that guides designers during projects design, construction and operation. This book introduces readers to key concepts of circularity in the built environment, highlight best practices, introduce opportunities to create value learn from real cutting edge case studies. In this book, we present a novel framework for regenerative building design that can be applied to future constructions based on professional expertise and exposure, towards healthy, resource efficient and green buildings in the AEC industry. We compare four state of the art buildings to address the critical principles, strategies and steps in the transition from the negative impact reduction architecture to the positive impact regenerative architecture, utilizing life cycle analysis. The case studies analysis and comparison can serve as an inspiring eye opener and provide a vision for architects and building professionals in the fields of high performance buildings, resource centered thinking and regenerative architecture.

This paper presents a model to simulate built-up expansion and densification based on a combination of a non-ordered multinomial logistic regression (MLR) and cellular automata (CA). The probability for built-up development is assessed based on (i) a set of built-up development causative factors and (ii) the land-use of neighboring cells. The model considers four built-up classes: non built-up, low-density, medium-density and high-density built-up. Unlike the most commonly used built-up/urban models which simulate built-up expansion, our approach considers expansion and the potential for densification within already built-up areas when their present density allows it. The model is built, calibrated, and validated for Wallonia region (Belgium) using cadastral data. Three 100 × 100 m raster-based built-up maps for 1990, 2000, and 2010 are developed to define one calibration interval (1990–2000) and one validation interval (2000 − 2010). The causative factors are calibrated using MLR whereas the CA neighboring effects are calibrated based on a multi-objective genetic algorithm. The calibrated model is applied to simulate the built-up pattern in 2010. The simulated map in 2010 is used to evaluate the model's performance against the actual 2010 map by means of fuzzy set theory. According to the findings, land-use policy, slope, and distance to roads are the most important determinants of the expansion process. The densification process is mainly driven by zoning, slope, distance to different roads and richness index. The results also show that the densification generally occurs where there are dense neighbors whereas areas with lower densities retain their densities over time. [less ▲]

This paper proposes a novel tracking state estimator to process both fast-rate synchronized phasor and slow rate SCADA measurements. The former are assumed to be in limited number. The latter are exploited as and when they arrive to the control center. In order to restore observability, after each execution of the tracking state estimator, forecasted SCADA measurements are used as pseudo-measurements in the next estimation. An event detection analysis allows assessing if the system is in quasi steady-state. If so, an innovation analysis is performed to identify and eliminate erroneous SCADA measurements. The system state is computed by Hachtel’s augmented matrix method. The option of exploiting time-tagged SCADA measurements is also considered. The method is illustrated through detailed dynamic simulations of a test system evolving towards voltage collapse, with and without emergency control. [less ▲]

This paper presents an experimental and numerical investigation of the power extraction from the oscillations of a square beam due to aeroelastic instabilities. The energy harvesting is performed using a coil-magnet arrangement connected to a variable resistance load with the target objective to auto-power a remote sensor. Two aeroelastic phenomena are investigated: Vortex Induced Vibration (VIV) and cross-flow galloping. The first instability (VIV) is analyzed on a free-standing vertical structure. A second experimental set-up is developed on a horizontal square cylinder supported by springs, free to oscillate vertically as a rigid body. In this case, both galloping and VIV interact, leading to interesting characteristics in order to harvest energy from the wind. The behavior of each electro-mechanical aeroelastic system is investigated for different reduced wind speeds and load resistances in a wind tunnel. Observed efficiencies are rather low, but large enough to power a remote sensor with an adapted measuring strategy. Both harvesting systems are then studied numerically using a wake oscillator model (for VIV) coupled to a quasi-steady model (for galloping) and an electric model (for the harvester). This mathematical model is used to extend the parametric space and to highlight the effectiveness of the high stable branch of the VIV-galloping curve to harvest energy. [less ▲]
