The present energy crisis and the awareness of the human impact on climate change have boosted the public debate on the accelerated deployment of renewable energy sources. The objective of this research project is to analyse and assess the landscape capacity and social attitudes towards wind energy parks in Belgium, especially in non-urban and non-industrial sites. This research project starts from the observation that a sustainable production of energy, relying on renewable resources, should go hand in hand with a sustainable societal support for the use of these renewable sources. Experiences from neighbouring countries showed that the societal support depends of the regional landscape capacity and the social attitudes towards wind energy parks. In this research project both quantitative and qualitative research techniques will be used to: (1) measure the landscape capacity in relation to the location of wind energy parks in Belgium, (2) to gain insight in the way attitudes towards wind energy parks are socially constructed and reproduced.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic airway inflammatory disease caused by repeated exposure to noxious gases or particles. It is now recognized that the disease also features systemic inflammation. The purpose of our study was to compare airway and systemic inflammation in COPD to that seen in healthy subjects and to relate the inflammation with the disease severity. METHODS: Ninety-five COPD patients, encompassing the whole severity spectrum of the disease, were recruited from our outpatient clinic and rehabilitation center and compared to 33 healthy subjects. Induced sputum and blood samples were obtained for measurement of inflammatory cell count. Interleukin (IL)-4, IL-6, IL-10, TNF-alpha and IFN-gamma produced by 24h sputum and blood cell cultures were measured. RESULTS: Compared to healthy subjects, COPD exhibited a prominent airway neutrophilic inflammation associated with a marked IL-10, IL-6 and TNF-alpha release deficiency that contrasted with a raised IFN-gamma production. Neutrophilic inflammation was also prominent at blood level together with raised production of IFN-gamma, IL-10 and TNF-alpha. Furthermore, sputum neutrophilia correlated with disease severity assessed by GOLD stages. Likewise the extent of TNF-alpha release from blood cells also positively correlated with the disease severity but negatively with that of sputum cell culture. Blood release of TNF-alpha and IL-6 negatively correlated with body mass index. Altogether, our results showed a significant relationship between cellular marker in blood and sputum but poor relationship between local and systemic release of cytokines. CONCLUSIONS: COPD is characterized by prominent neutrophilic inflammation and raised IFN-gamma production at both bronchial and systemic level. Overproduction of TNF-alpha at systemic level correlates with disease severity and inversely with body mass index. [less ▲]

Several factors, including fruit and vegetables intakes, have been shown to significantly influence the plasma concentrations of the two antioxidants vitamin C and β-carotene. Deficiency levels of 6 mg/L (34.2 μM) for vitamin C and of 0.22 mg/L (0.4 μM) for β-carotene have been suggested below which cardiovascular risk might be increased. The present study performed on 897 presumably healthy subjects aged 40–60 years aimed to examine how modifiable lifestyle factors may be related to vitamin C and/or β-carotene deficiency. Gender, smoking, lack of regular physical activity and of daily fruit consumption (≥2/day), and social status (in particular, unemployment) were found to be significant risk factors for vitamin C deficiency. For β-carotene deficiency, the same factors were identified except social status; moreover, overweight and OC use in women were also found to have a deleterious effect. For non exposed subjects, the probability of developing vitamin C deficiency was 4% in men and 2.4% in women. This probability increased to 66.3% for men and to 44.3% for women (and even to 50.4% under OC use), when all risk factors were present. For β-carotene deficiency, the corresponding probabilities were equal to 29.7% in men and 13.7% in women (no risk factor present), and to 86.1% for men and 69.9% (91.6% for OC use) for women (all factors present), respectively [less ▲]

In this paper, we introduce a notion of weak pointwise Hölder regularity, starting from the definition of the pointwise anti-Hölder irregularity. Using this concept, a weak spectrum of singularities can be defined as for the usual pointwise Hölder regularity.We build a class of wavelet series satisfying the multifractal formalism and thus show the optimality of the upper bound. We also show that the weak spectrum of singularities is disconnected from the casual one (referred to here as strong spectrum of singularities) by exhibiting a multifractal function made of Davenport series whose weak spectrum differs from the strong one.

Two types of nucleolus can be distinguished among eukaryotic cells: a tri-compartmentalized nucleolus in amniotes and a bi-compartmentalized nucleolus in all the others. However, though the nucleolus' ultrastructure is well characterized in mammals and birds, it has been so far much less studied in reptiles. In this work, we examined the ultrastructural organization of the nucleolus in various tissues from different reptilian species (three turtles, three lizards, two crocodiles, and three snakes). Using cytochemical and immunocytological methods, we showed that in reptiles both types of nucleolus are present: a bi-compartmentalized nucleolus in turtles and a tri-compartmentalized nucleolus in the other species examined in this study. Furthermore, in a given species, the same type of nucleolus is present in all the tissues, however, the importance and the repartition of those nucleolar components could vary from one tissue to another. We also reveal that, contrary to the mammalian nucleolus, the reptilian fibrillar centers contain small clumps of condensed chromatin and that their surrounding dense fibrillar component is thicker. Finally, we also report that Cajal bodies are detected in reptiles. Altogether, we believe that these results have profound evolutionarily implications since they indicate that the point of transition between bipartite and tripartite nucleoli lies at the emergence of the amniotes within the class Reptilia.

La sociologie du droit en France, au même titre que la sociologie juridique dans n’importe quel autre pays, est déterminée par les conditions historiques dans lesquelles le champ juridique s’est construit ainsi que par les relations qui se sont établies entre le droit, le pouvoir politique et l’Etat. Cet article propose de présenter les enjeux auxquels fait face la sociologie du droit en portant une attention particulière au contexte social et politique dans lequel elle s’est développée au sein de l’Hexagone. Cet article pose l’hypothèse d’une faible institutionnalisation de la sociologie du droit dans ce pays, que nous proposons d’expliquer par sa construction historique « à l’ombre du droit », ainsi que par l’éclatement des différents groupes, courants et tendances qui la composent à l’heure actuelle.

Questionner le tourisme rural, c’est se poser la question des particularités de celui-ci notamment liées à sa dispersion, à ses difficultés d’organisation en une « destination », à ses représentations idylliques, à ce patrimoine plus ou moins commun, plus ou moins privatisé, que le touriste consomme, aux difficiles questions du partage des revenus du développement touristique, aux problèmes des équipements et surtout de l’accessibilité par transports individuels et collectifs de ces zones excentrées. Autour de quelques collègues soucieux de partager leur enthousiasme pour la recherche, nous avons convié des doctorants à partager dans le cadre d’une journée de l’école doctoral thématique en géographie auprès du Fonds National de la Recherche Scientifique, leurs interrogations et leurs premières investigations. Ce numéro thématique rassemble les principales contributions à cette réflexion commune, en proposant une étude de l'utilisation de l’autoroute pour développer des produits touristiques à proximité d’un flux important de personnes (Malet, 21-35), une analyse de la mise en tourisme d'un produit de terroir et de la manière d'en faire une ressource clé du tourisme régional (De Myttenaere, 37-51), une recherche sur les images et représentations d'une destination rurale et leur utilisation pour développer l’accueil et la promotion (Mazuel et Bonniot, 7-19), une enquête sur le rôle des associations intercommunales et des municipalités dans le développement des entreprises touristiques en milieu rural (Vanneste et Ryckaert 53-71), une réflexion sur la complexité des polémiques autour des loisirs motorisés (Haye et Mounet, 73-84) et enfin une lecture critique de textbooks anglais qui permet de constater le chemin fait et le chemin qui reste à faire pour réellement passer des monographies à des théories du tourisme sensibles aux particularités du milieu rural (Dubois, 85-94).

We use the Earth system model of intermediate complexity LOVECLIM to show the effect of coupling interactive ice sheets on the climate sensitivity of the model on a millennial time scale. We compare the response to a 2xCO2 warming scenario between fully coupled model versions including interactive Greenland and Antarctic ice sheet models and model versions with fixed ice sheets. For this purpose an ensemble of different parameter sets have been defined for LOVECLIM, covering a wide range of the model's sensitivity to greenhouse warming, while still simulating the present-day climate and the climate evolution over the last millennium within observational uncertainties. Additional freshwater fluxes from the melting ice sheets have a mitigating effect on the model's temperature response, leading to generally lower climate sensitivities of the fully coupled model versions. The mitigation is effectuated by changes in heat exchange within the ocean and at the sea-air interface, driven by freshening of the surface ocean and amplified by sea-ice-related feedbacks. The strength of the effect depends on the response of the ice sheets to the warming and on the model's climate sensitivity itself. With the ensemble approach in this study we cover a wide range of possible model responses. [less ▲]

Flood management is more than ever an issue for dam designers and engineering consulting firms in charge of rehabilitation works. Piano Key Weirs are a new cost-effective type of spillway designed to improve dams discharge capacity. These structures are particularly attractive: they can easily be built on existing structures and enable very high discharge capacities. Therefore, Piano Key Weirs are nowadays studied worldwide. Piano Key Weir description involves a lot of geometrical parameters (more than 30), which designations are not already universally defined. A naming convention is required to enhance exchanges and cooperation between the numerous developers. A naming convention has been developed at EDF – Hydro Engineering Center in cooperation with the Laboratory of Hydraulic Constructions (LCH), Ecole Polytechnique Fédérale de Lausanne and the Laboratory of Hydrology, Applied Hydrodynamics and Hydraulic Constructions (HACH), University of Liege. This paper describes the proposed naming convention and gives definitions and notations of the various geometrical parameters. This work represents a first attempt which should be updated with the contribution of stakeholders involved in this topic. [less ▲]
