Les résultats obtenus dans le cadre du suivi DCE 2006 du phytoplancton des eaux côtières corses ont permis: − de tester et de valider une stratégie d’échantillonnage originale adaptée aux réseaux de surveillance et aux spécificités régionales; − de caractériser globalement les communautés phytoplanctoniques de 6 masses d’eau côtières ne présentant pas de risque NABE à l’horizon 2015 (Calvi, Cargèse, Pianottoli, Est Cap Corse, Sud Bastia et Sant’Amanza); - de démontrer le très bon état des masses d’eaux échantillonnées pour l’indicateur Phytoplancton; - d’émettre des recommandations visant à optimiser l’effort d’échantillonnage et la validité des résultats. La stratégie d’échantillonnage testée et validée propose de réaliser deux suivis « haute fréquence » au niveau des sites de référence de Calvi et de la station « Sud Bastia ». L’échantillonnage doit être réalisé en subsurface toute l’année, une fois par semaine de janvier à juin et une fois par quinzaine de juillet à décembre. Les autres masses d’eau sont échantillonnées une fois par mois, de janvier à décembre. Les résultats 2006 mettent en évidence les caractéristiques communes des communautés phytoplanctoniques des masses d’eau de Calvi, Cargèse et Pianottoli et des masses d’eau Est Cap Corse, Sud Bastia et Sant’Amanza. Ceci suggère que les suivis réalisés dans le cadre des contrôles de surveillance pourraient se limiter aux observations « haute fréquence » réalisées à Calvi et à la station « Sud Bastia ». [less ▲]

The paper deals with a new finite element scheme for non-destructive eddy-current testing (ECT) problems involving multiply connected test pieces and differential probes. It concerns a perturbation technique applied to the magnetodynamic h - phi formulation. The unperturbed field (in the absence of the flaw) is conventionally computed in the complete domain. The source of the perturbation problem is then determined by the projection of the unperturbed field in a relatively small region around the defect, the optimum size of which depends on the working frequency. The discretisation of this reduced domain is well adapted to the size of the defect and chosen independently of the dimensions of the excitation probe and the specimen under study. At a discrete level, the voltage change is efficiently computed by integration only over the defect and a layer of elements in the reduced domain that touches the defect's boundary. The accuracy of the proposed perturbation model is illustrated by comparison of the results obtained for different dimensions of the reduced domain with those achieved in the conventional way. The considered test case involves a differential probe scanning the outer surface of a metal tube for the detection of through-wall cracks. [less ▲]

Matrix metalloproteinases (MMPs) have been implicated in numerous tissue-remodeling processes. The finding that mice deficient in collagenase-2 (MMP-8) are more susceptible to develop skin cancer, prompted us to investigate the role of this protease in cutaneous wound healing. We have observed a significant delay in wound closure in MMP8-/- mice and an altered inflammatory response in their wounds, with a delay of neutrophil infiltration during the first days and a persistent inflammation at later time points. These changes were accompanied by alterations in the TGF-beta1 signaling pathway and by an apoptosis defect in MMP8-/- mice. The delay in wound healing observed in MMP8-/- mice was rescued by bone marrow transplantation from wild-type mice. Analysis of other MMPs showed that MMP8-/- mice had a significant increase in the expression of MMP-9, suggesting that both proteases might act coordinately in this process. This possibility was further supported by the novel finding that MMP-8 and MMP-9 form specific complexes in vivo. Taken together, these data indicate that MMP-8 participates in wound repair by contributing to the resolution of inflammation and open the possibility to develop new strategies for treating wound healing defects.

The paper explores the concept of the 'Center of the Main Interests' which plays a key role under the European Insolvency Regulation to allocation jurisdiction in international insolvency proceedings. The paper reviews the case law of courts of EU Member States and the first cases decided by the European Court of Justice in order to draw some preliminary lessons on how to identify where the Center of the Main Interests of the debtor lies.

Motivated by neutron scattering experiments, we investigate the decay of the fidelity with which a wave packet is reconstructed by a perfect time-reversal operation performed after a phase-space displacement. In the semiclassical limit, we show that the decay rate is generically given by the Lyapunov exponent of the classical dynamics. For small displacements, we additionally show that, following a short-time Lyapunov decay, the decay freezes well above the ergodic value because of quantum effects. Our analytical results are corroborated by numerical simulations. [less ▲]

The generation of glutamatergic neurons by stem and progenitor cells is a complex process involving the tight coordination of multiple cellular activities, including cell cycle exit, initiation of neuronal differentiation and cell migration. The mechanisms that integrate these different events into a coherent program are not well understood. Here we show that the cyclin-dependent kinase inhibitor p27Kip1 plays an important role in neurogenesis in the mouse cerebral cortex, by promoting the differentiation and radial migration of cortical projection neurons. Importantly, p27Kip1 promotes neuronal differentiation and neuronal migration via two distinct mechanisms, which are themselves independent of the cell cycle regulatory function of p27Kip1. p27Kip1 inactivation by gene targeting or RNA interference results in neuronal differentiation and radial migration defects, demonstrating that p27Kip1 regulates cell migration in vivo. The differentiation defect, but not the migration defect, is rescued by overexpression of the proneural gene Neurogenin 2. p27Kip1 acts by stabilizing Neurogenin 2 protein, an activity carried by the N-terminal half of the protein. The migration defect resulting from p27Kp1 inactivation is rescued by blocking RhoA signalling, an activity that resides in the c-terminal half of p27Kip1. Thus, p27Kip1 plays a key role in cortical development, acting as a modular protein that independently regulates and couples multiple cellular pathways contributing to neurogenesis. [less ▲]

In the present study, published Miocene mega- and microfloral records compiled from a total of 92 localities in Western Eurasia are analysed with respect to diversity of different plant functional types (PFTs). To study spatial diversity patterns and their evolution three time-intervals are selected corresponding to the Langhian (16.3-13.6 Ma), the Serravallian (13.6-11.6), and the earlier part of the Tortonian (11.6-8.5 Ma). First all arboreal species occurring in the floras are classified using a total of 13 different PFTs (functional types of trees and climatically defined subtypes). In a next step, diversity spectra with respect to these PFTs are generated for each site. Cluster analysis is then performed in order to obtain groups of floras with similar spectra that are interpreted in terms of vegetation type. Their spatial distribution in each time-interval is shown in maps. According to these results, zonally arranged patterns are obtained. Broadleaved Deciduous Forests are most important in the higher latitudes while Mixed Mesophytic Forests dominate the mid-latitudes in Western Eurasia. Broadleaved Evergreen Forests are of minor importance in the area of interest. The observed diversity patterns and their changes in time are correlated with spatial climate patterns and the continental palaeoclimate evolution. During the late Miocene cooling, Broadleaved Evergreen Forests completely disappear from the mid-latitudes of Western Eurasia, and Mixed Mesophytic Forests of the mid-latitudes are mostly replaced by broadleaved deciduous vegetation types. In the context of this cooling, a drier season became established in Western Europe during the Tortonian, as is evident from reconstructed arboreal diversity data and precipitation data. In Central Europe, vegetation types indicating permanently humid conditions persisted throughout all the three time-intervals analysed. (C) 2007 Elsevier B.V. All rights reserved. [less ▲]

About a decade ago the Belgian Hypertension Committee endorsed the guidelines for the management of hypertension as proposed by the World Health Organization (WHO) and the International Society of Hypertension (ISH) in 1999. These guidelines have been adapted by the European Societies of Hypertension and of Cardiology in 2003 and more recently in 2007. The core of the document consists of the classification of hypertension according to blood pressure, the evaluation and global risk stratification of the individual patient, and the guidelines for management, non-pharmacological measures and antihypertensive drug treatment. The document also includes information on epidemiology, risk factors, complications of hypertension and the results from large intervention trials with regard to morbidity and mortality. The present manuscript will mainly cover those aspects which are of practical importance for the physician. [less ▲]

The 50-m high arch dam of Esch-sur-Sûre, built on the river Sûre between 1956 and 1957, is located 1.2 km upstream of the town of esch-sur-Sûre in the north west of Luxembourg. As the dam is not equipped with a surface spillway, the construction of a new one is considered necessary. The new spillway design with a discharge capacity of 400 m³/s consists in building two labyrinth weirs discharging into a spillway tunnel passing under the left dam abutment. [less ▲]
