The Piano Key Weir (PKW) is a weir of particular geometry, associating to a labyrinth shape the use of overhangs to reduce the basis length. The PKW can thus be directly placed on a dam crest. Together with its important discharge capacity for low heads (several times the one of a linear Creager weir), this geometric feature makes the PKW an interesting solution for dams rehabilitation as well as new constructions. However, PKW constitutes a new type of weir, firstly designed in 2001 and built for the first time in 2006 by EDF. With several researches and projects on PKW all over the world, the workshop about Labyrinth and Piano Key Weirs aimed at bringing together all the people (engineers, researchers,...) interested to state and summarize the current knowledge on this still non conventional hydraulic structure. The main themes tackled during the conference concern followings: • Physical Modeling. Hydraulic capacity • Physical Modeling. Downstream fittings • Numerical Modeling • Hydraulic Design • Planned and achieved projects • Nomenclature, Database, Future developments The papers reviewed and accepted by an International Scientific Committee and presented during the workshop sessions are published in the present book which constitutes a reference on the subject.

Dam engineering is currently experiencing a strong revival of labyrinth oriented weirs. Labyrinth weirs, with a repetitive constructional character and an increased specific discharge capacity, are a very good technico-economical compromise. The concept of Piano Key Weir (PKW), with alveoli developed in overhangs from a reduced support area, enables to install non-linear crests at the top of concrete dams. It eliminates thus the main drawback of classical labyrinth weirs and enables their use to rehabilitate numerous existing dams. Since the first implementation of PKW by Electricité de France on Goulours dam (France) in 2006, at least eight PKWs have been built in France, Vietnam and Switzerland. Their operation over a few years has already provided the first prototype data. Other projects are under study, construction or planning in varied countries. On another hand, research programs are under progress all over the world. Following a first edition in Liege (Belgium) in 2011, the 2nd international workshop on Labyrinth and PKW aims at bringing together people with varied background (engineers, researchers,...) to state and summarize the current knowledge on these still non-conventional hydraulic structures. The papers reviewed and accepted by an International Scientific Committee and presented during the workshop sessions are published in the present book which can be considered as an up-to-date Reference document.

Since the first implementation by Electricité de France on Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dams’ projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world. Besides, more than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the books of proceedings of two first workshops held in Liege (Belgium – 2011) and Paris (France – 2013), this book gathered all the contributions presented by people with varied background, from researchers to practitioners, during the 3rd international workshop on Labyrinth and Piano Key weirs, organized in Qui Nhon, Vietnam. These papers, reviewed and accepted by an International Scientific Committee, summarize the current knowledge on Piano Key Weir, from a theoretical to a practical point of view, and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering. [less ▲]

L’époque des pères fondateurs de l’Europe nous paraît aujourd’hui bien lointaine. La construction de l’Union européenne donne le sentiment d’être le fruit de la communion des États et de leur population, mus par un même élan d’enthousiasme. L’abandon d’une Constitution pour l’Europe lors du refus français et néerlandais semble pourtant aller à l’encontre de cet enthousiasme : le rêve européen se serait-il brutalement interrompu ? La construction européenne serait-elle remise en question ? Partant de ces questions très souvent soulevées et débattues, cet ouvrage démontre que la réalité est bien plus complexe qu’une opposition « stop ou encore » et que la ratification des différents traités européens, par les États membres et leur population, ne fut pas toujours acquise sans heurt. Au travers d’une analyse systématique des votes des assemblées parlementaires et des résultats des referenda, l’ouvrage confronte ces présupposés à la « dure » réalité des urnes et laisse apparaître certaines nuances concernant, notamment, le fait que le Royaume-Uni et la Pologne ne sont pas nécessairement les États les plus « eurosceptiques » ou que les conséquences des referenda danois, irlandais ou français étaient vraisemblablement prévisibles.

Comment exposer des objets que la colonisation a arrachés à un continent pour les faire parvenir en Europe où ils furent tour à tour considérés comme des curiosités, des vestiges d’une civilisation sauvage et archaïque, des témoins de l’enfance de l’humanité, avant d’appartenir aux catégories de l’ « art nègre », des « arts primitifs » et, plus récemment, des « arts premiers » ? Les logiques évolutionnistes et différentialistes qui ont dicté les choix muséographiques des musées d’histoire naturelle et des premiers musées d’ethnographie ont-elles réellement disparu ? Le regard sur l’autre a-t-il changé, y compris dans les musées qui, sous l’impulsion du primitivisme, ont contribué à la reconnaissance des arts de l’Afrique ? Ces questions, qui portent sur l’ évolution du regard porté sur les objets africains et leur représentation depuis le XIXe siècle jusqu’à l’ époque post-coloniale, forment le point de départ de l’exposition Labyrinthe-Fétiches. Conçue par l’artiste Toma Muteba Luntumbue à partir des collections africaines de l’Université de Liège, cette exposition nous invite à déambuler dans le labyrinthe des idées et des préjugés qui ont inspiré la collecte, l’étude, la muséalisation, puis la sacralisation d’objets désormais enfermés dans une « prison de sens ». En reconstitant, dans l’espace de la Cité Miroir, les différents modes de classement et dispositifs de présentation des objets africains, Toma Muteba Luntumbue entend montrer combien leur présence muséale et leur artification les a définitivement privés de leur identité culturelle et de leur appartenance structurelle initiale. Ce phénomène de patrimonialisation a non seulement changé le sens et le statut de ces objets, mais il en a fait de nouveaux fétiches. Ce terme, utilisé dès le XVIe siècle pour qualifier des artefacts cultuels rapportés d’Afrique et repris à l’époque coloniale pour désigner avec dédain la statuaire africaine, revit aujourd’hui à travers la dimension iconique et sacrée que l’on attribue à ce que l’on nomme, à tort, le « patrimoine africain ». Devenus intouchables, alors qu’ils sont parvenus à nous dans une situation d’arrachement, de violence et de mépris, les objets d’art africain sont à présent figés dans une autre histoire typiquement occidentale, celle du « patrimoine mondial de l’humanité ».

We have numerically studied a model of granular landscape eroded by wind. We show the appearance of labyrinthic patterns when the wind orientation turns by 90 degrees. The occurrence of such structures is discussed. Moreover, we introduce the density n(k) of "defects" as the dynamic parameter governing the landscape evolution. A power-law behavior of n(k) is found as a function of time. In the case of wind variations, the exponent (drastically) shifts from two to one. The presence of two asymptotic values of n(k) implies the irreversibility of the labyrinthic formation process. [less ▲]

The paper exposes the main lines of french republican secularism as oposed to belgian neutrality. It shows how the former presuposes a basic distrust again religion, while the latter is mainly based on equal treatment. The link is also made whith the growing xenophobia in Europe and the way "secularism" is sometimes used to hide what is in fact a xenophobic position. [less ▲]

Tumour necrosis factor (TNF)alpha is a cytokine endowed with potent inflammatory properties that may contribute to airway inflammation in asthma. It has previously been shown that the single base pair polymorphism-308 (G to A substitution) in the promoter of TNFalpha gene results in enhanced cytokine secretion. Whether this polymorphism is associated with the presence of phenotypic expression of asthma is questioned. In this study the relative frequency of TNF1 and TNF2 alleles in a population of adult healthy subjects (n=98) and adult Caucasian asthmatics (n=95) was compared taking into account their disease severity, atopic status and their smoking habit. For the whole group of asthma the genotype frequency for 1/1, 1/2, 2/2 were 67%, 33% and 0%, respectively, and not significantly different from those found in the control group that reached 70%, 28% and 2% respectively (p>0.05). The allele frequencies in asthma were 86% and 14% for TNF1 and TNF2 respectively while the corresponding figures were 85% and 15% in the control group (p>0.05). Furthermore, subdividing asthmatics into severe forced expiratory volume in one second <60% pred), atopic or smoking patients did not show any significant association with this TNFalpha polymorphism. To conclude the polymorphism -308 in the promoter of the TNFalpha gene does not confer a susceptibility to develop asthma nor to grade its severity. [less ▲]
