In order to operate an electrical distribution network in a secure and cost-efficient way, it is necessary, due to the rise of renewable energy-based distributed generation, to develop Active Network Management (ANM) strategies. These strategies rely on short-term policies that control the power injected by generators and/or taken of by loads in order to avoid congestion or voltage problems. While simple ANM strategies would curtail the production of generators, more advanced ones would move the consumption of loads to relevant time periods to maximize the potential of renewable energy sources. However, such advanced strategies imply solving large-scale optimal sequential decision-making problems under uncertainty, something that is understandably complicated. In order to promote the development of computational techniques for active network management, we detail a generic procedure for formulating ANM decision problems as Markov decision processes. We also specify it to a 75-bus distribution network. The resulting test instance is available at http://www.montefiore.ulg.ac.be/~anm/ . It can be used as a test bed for comparing existing computational techniques, as well as for developing new ones. A solution technique that consists in an approximate multistage program is also illustrated on the test instance. [less ▲]

Les caractéristiques du récit d’anticipation en font un objet privilégié d’étude des enjeux culturels d’une époque dont il dépeint le tableau futur pour critiquer son état actuel ou s’en rassurer. Le genre de l’anticipation est ainsi enclin à articuler imaginaire social et extrapolations du présent, ce qui le porte à considérer, parmi d’autres aspects socio-culturels, la situation de la littérature. Il traite volontiers du modèle culturel lettré en questionnant son histoire, ses valeurs, ses acteurs et ses institutions. Le bilan qu’il en fait est généralement nuancé et négatif, prenant la forme de fictions dystopiques qui multiplient les alternatives audio-visuelles à l’objet-livre, doutent de Paris en tant que capitale des lettres et questionnent le paradigme de la France comme nation littéraire. Dès 1860, des romans et nouvelles parus pour la plupart dans la presse et les collections populaires développent de telles représentations en mots et en images. Outre l’œuvre d’anticipation d’Albert Robida, qui n’a pas seulement illustré La fin des livres d’Octave Uzanne (1895) mais aussi développé une réflexion d’ensemble sur l’avenir des pratiques littéraires et artistiques, notamment dans le Vingtième Siècle (1883) et La Vie électrique (1890), mentionnons Jules Verne et son Paris au XXe siècle (1994, écrit en 1863) ou Camille Flammarion avec La Fin du monde (La Science illustrée, 1893). Parmi les moins connus, signalons encore Joseph Méry, Les Ruines de Paris (1856) ; Alfred Franklin, Les Ruines de Paris en 4875 (1875) ; Didier De Chousy, Ignis (1883) ; Gustave Guitton, Ce que seront les hommes de l’an 3000 (1907) et Octave Béliard, Une expédition polaire aux ruines de Paris (Lecture pour tous, 1911). Dans ces œuvres encore peu considérées par la recherche universitaire, la littérature apparaît comme un bien culturel éminemment périssable et menacé, mais aussi comme un médium parmi d’autres au sein de pratiques en mutation qui réorganisent les tensions entre la création désintéressée et la production utilitaire. Si la littérature n’est pas le livre, le destin incertain de la première semble indissociablement lié à l’avenir du second. Des ambiguïtés significatives sont à examiner à ce propos : les scénarios fictifs envisagent une fin possible de la culture lettrée qui ne signe pas toujours la mort du livre et imaginent à celui-ci une survie sous des formes alternatives. Ces dernières révèlent un imaginaire médiatique du progrès et une inscription dans la société du spectacle émergente. Pour en rendre compte, on s’interrogera donc sur ce point crucial : y a-t-il disparition ou substitution du livre dans le corpus d’anticipation ? Sous cet angle, la lecture transversale permettra d’esquisser une typologie du livre au futur antérieur selon quatre aspects : (1) ses formes et supports (fragment vs volume, archive documentaire, hybride audio-visuel, objet technologique, etc.), (2) ses lieux matériels et symboliques (bibliothèques et cabinets, topographie urbaine, architecture dédiée), (3) ses usages (individuels vs collectifs, publics vs privés, informels ou ritualisés) et (4) les systèmes de classements dans lesquels il s’inscrit (hiérarchie des genres, valeurs, promotion ou contestation). Ces éléments d’analyse doivent permettre de rendre compte de l’empreinte complexe laissée au XIXe siècle par une certaine culture du livre dans une fraction de la production littéraire particulièrement perméable aux préoccupations et au discours social de son époque. Ils permettront de préciser l’importance assignée au livre dans son double aspect d’objet patrimonial et de vecteur de communication. [less ▲]

In this paper I look at the particular situation of Congolese and Belgian-Congolese citizens in Belgium, the former colonial metropole. From research conducted over ten years within Congolese circles I argue that postcolonial immigrants/citizens have for the last three decades been experiencing a significant social malus. Not only does daily racial discrimination inform and supply it but so also does treatment by the state itself through its various institutions. Looking at some data collected from political, associative and artistic spheres I argue that the Congolese in Belgium have to deal with a postcolonial malus. My research is grounded on a comprehensive anthropology which privileges the actors’ own perspective. I thereby explore the elements, trends or configurations of the post-migratory situation which may be considered inherited from colonialism. Finally, I discuss the reason why despite three decades of “postcolonial activism”, the postcolonial critique is not a live social issue in French-speaking Belgium. [less ▲]

The resulting framework contains eleven indicators which are the most acceptable set of indicators for all the stakeholders. It answers to European legislation and strategies for biodiversity. It is intended to improve sustainability in the quarries and to help managing biodiversity, to allow setting up of appropriate reporting systems. The aim is to maintain the biodiversity status of the gypsum quarries. It is a flexible framework adaptable given the local context of each gypsum quarry in order to prove if a No Net Loss has been reached at a quarry’s scale. [less ▲]

Epitaxy of metal oxides is of great interest since it provides a way to obtain desired novel properties for the applications such as electronics and energy. However, earlier epitaxy research's have been restricted because of the limited range of compositions and low-index of commercially available single crystal substrates. Consequently, novel epitaxy synthesis methods need to be developed in order to go beyond the present demands of of single crystal substrates in terms of phase, composition, size, orientation and symmetry. In this research work, we have developed a high-throughput synthesis process, called combinatorial substrate epitaxy (CSE), where an oxide film is grown epitaxially on a polycrystalline substrate. As a proof-of-concept, we firstly fabricated Ca3Co4O9 films on Al2O3 ceramics. Films have a good local epitaxial registry, and the Seebeck coefficient is about 170 µV/K at 300 K. High quality BiFeO3/La0.7Sr0.3MnO3 thin film heterostructures were secondly deposited on dense LaAlO3 ceramics prepared by spark plasma sintering. Piezoforce microscopy was used to confirm the local ferroelectric properties. Thirdly, we investigate the growth of of metastable monoclinic Dy2Ti2O7 epitaxial films on polycrystalline La2Ti2O7 substrates. We conclude that CSE approach opens the way towards unexpected electronic properties in oxide films. [less ▲]

Nine neurodegenerative disorders, referred to as polyglutamine diseases and including Huntington’s disease, are associated with the abnormal expansion of a polyglutamine tract inside nine unrelated proteins. This polyQ expansion is thought to be the major determinant in the development of neurotoxicity, triggering protein aggregation into amyloid fibrils. A large body of evidence however suggests that non-polyQ regions modulate the aggregation process triggered by polyQ expansions. The interplay between the polyQ tract and non-polyQ regions is complex and still not fully understood. In order to better understand it, we previously designed and characterized model polyQ proteins made of the beta-lactamase BlaP with 23, 30, 55 and 79Q inserted at position 197 or 216. Our first results had indicated that our model is relevant to study polyQ aggregation since it recapitulates the aggregation properties of polyQ disease-associated proteins: there is a Q-threshold for the spontaneous formation of amyloid fibrils in solution, and above the threshold, the longer the polyQ, the faster the aggregation. Moreover, the structure of BlaP and the position of insertion of the polyQ tract influence their aggregation properties in solution. This work aims to better understand, at the molecular level, (i) the precise role of the polyQ length (23, 30, 55, 61, 67, 73 and 79Q), (ii) the conformation of the host protein (native or unfolded BlaP), (iii) the location of the polyQ tract within BlaP (197 or 216), (iv) the flexibility of the polyQ flanking sequences, and (v) the origin of constraints applied by BlaP to the inserted polyQ tract (at its N- or C-terminal end) on the structural, thermodynamic and aggregation properties of BlaP-polyQ chimeras, using a wide range of biophysical techniques (e.g., spectroscopy methods, quartz crystal microbalance, atomic force microscopy and dynamic light scattering). The effect on the aggregation properties will be determined on the spontaneous aggregation into amyloid fibrils in solution, and on the nucleation and on the elongation steps of amyloid fibril formation. For this purpose, new chimeras containing 61, 67 and 73Q at position 197, or 55Q inserted at position 197 in between two different protease’s cleavage sites, that are relatively flexible, will be moreover created. Our results first demonstrate that the spontaneous aggregation into amyloid fibrils in solution is correlated to the polyQ length with an exponential growth function, and that the elongation rate is linearly correlated to the polyQ length, independently of the protein context (i.e., conformation of BlaP, and/or location of the polyQ tract, and/or polyQ peptides inserted or not within BlaP). However, the location of the polyQ tract inside BlaP, and/or its conformational state, and/or the flexibility of polyQ flanking sequences, and/or the origin of constraints applied to the polyQ tract drastically influence the ability of a polyQ tract to trigger the nucleation and/or the elongation step of amyloid fibrils (variation in the Q-threshold and in the absolute rate of both steps). Altogether, our results suggest that non-polyQ regions constitute an additional potential therapeutic target, more specific than drugs targeting the polyQ sequence, to interfere with the nucleation and/or the elongation of amyloid fibrils, associated to neurotoxicity. A possible drug could be constituted by a ligand specific to non-polyQ regions of disease-associated proteins, which further increases the constraints applied to the polyQ expansion to prevent the disease onset and/or progression.

In this article, we go back on two ways of taking into account the environmental dimension in urban planning and governance. We stress the difficult articulation between these two approaches – “urban ecology” and “urban environment” – and the actual impasse the discipline of urban planning finds itself in in its quest of the sustainable city. These two approaches for acting on the city by considering the complexity of its milieu build on different representations of this milieu and different modes of action legitimation. Negating each other, they can difficultly coexist, even less articulate. Through the example of water management in Cochabamba, we stress the tensions between these approaches. We point also to the awkward and marginalized position of urban planning and challenges it must face to regain a capacity of action in contemporary fragmented cities that know complex governance landscapes and rare or endangered resources.

In the economic and energy context of our society, it is universally recognized that alternatives to petrochemicals products must be found. To overcome this problem, renewable lignocellulosic biomass could be used to produce high value products. To achieve this objective, pretreatment processes are required to allow the breakdown of lignocellulosic structure and increase accessibility of the material. In this way, steam explosion is a thermo-mechano-chemical pretreatment which allows the opening of lignocellulosic material structural components and includes modifications of the physical properties of the material, hydrolysis of hemicellulosic components and modification of the chemical structure of lignin [1]. This study is focused on the impact of various steam explosion treatments on the chemical configuration of tall fescue lignin. NMR analyses perform on the Festuca L. pretreated samples show variations of links with treatment intensity. Observations show double phenomen :re-polymerization and depolymerization of the lignin structure during steam explosion process [2]. In parallel, HPSEC analyses show modifications in the molecular weight of the lignin obtained after the steam explosion treatment. [less ▲]

As used by Egyptians for irrigation and reported by Archimedes, a screw turning inside a hollow pipe can pull out a fluid againt gravity. At a centimetric scale, an analagous system can be found with a drop pending on a rotating spiral which is tilted toward the horizontal. The ascent of the drop to the top of the spiral is considered and a theoretical model based on geometrical considerations is proposed. The climb of the drop is limited by the fluid deposition on the screw at high capillary number and by a centrifugation phenomenon. We find out the range of fluid proprities and spiral characteristics for which an ascending motion of the drop is possible. Finally we discuss the efficiency of such system to extract a fluid from a bath at a centrimetric scale. [less ▲]
