Dans une section de colloque intitulée « Hommes, Église, Institutions à l’époque moderne », il est important de faire entendre des voix de femmes, qui, sans avoir la notoriété et la science des moniales de Port-Royal, n’en ont pas moins imité l’audace et tenté de résister aux injonctions de l’autorité ecclésiale au nom de leur conscience. Cette communication fera le point sur l’apport de certaines collections d’archives produites en interne par des religieuses qui recourent à l’écrit pour défendre leur point de vue face aux instances dirigeantes – annales, abrégés de vertus et correspondances – et sur d’autres documents où la voix de ces femmes est relayée et commentée par les gens d’Église venus les interroger – scrutins et rapports de visites régulières. Cette question sera plus spécialement examinée dans le contexte de la lutte menée par le pouvoir épiscopal au diocèse de Liège contre divers membres du réseau janséniste soupçonnés de semer le trouble dans plusieurs communautés féminines à la fin du XVIIe et au début du XVIIIe siècle. On tentera une analyse de discours croisés entre partis féminins, parfois opposés, et réactions masculines, tout aussi diversifiées, en présentant deux études de cas touchant les sépulcrines de Bouillon et de Marchienne-au-Pont, d’une part, et les deux communautés d’annonciades célestes de Liège, d’autre part [less ▲]

L’utilisation de l’argile en construction permet d’atteindre des propriétés spécifiques en termes de résistance mécanique et d’inertie thermique. Les recherches menées à l’Université de Liège, en collaboration avec l’entreprise MOBIC, ont permis de développer des produits permettant l’amélioration de l’inertie thermique de panneaux à ossature bois. L’effet de l’apport de la couche d’inertie au sein des constructions à ossature bois a été quantifié expérimentalement par l’instrumentation de modules jumeaux de 20m². Cet effet sur le confort thermique a également été modélisé par des simulations thermiques en vue de quantifier les bénéfices sur les surchauffes en été, les réductions des consommations énergétiques en hiver pour divers scénarii au moyen d’un programme de simulation dynamique des échanges thermiques et des bilans d’énergie au sein de bâtiments [less ▲]

La fin de la puissance française à Gênes est marquée par une révolte qui renversa le pouvoir de Charles VI. Prenant la route de la capitale ligure, le gouverneur royal, le maréchal Jean Le Meingre, dit Boucicaut, alors en Lombardie, regroupa autour de lui une armée composée de troupes françaises et piémontaises, le prince d'Achaïe et comte de Piémont étant à l'époque un de ses plus fidèles alliés, si pas le dernier en terre d'Italie. C'est à l'étude de cette société militaire particulière, organisée autour d'une personnalité et en perpétuelle recomposition – à la suite entre autres de l'envoi de renforts depuis Paris – que nous nous intéresserons dans le cadre de cette communication. Il s'agira dans un premier temps de dresser le profil de cette compagnie, en mettant avant tout en évidence la place que jouèrent dans son organisation les réseaux de sociabilité du maréchal de France – expérience des expéditions d'Orient, ordre de l'écu vert à la dame blanche... On y rencontrera certains des plus fidèles compagnons d'armes du maréchal, dont certains furent à ses côtés lors de la bataille d'Azincourt, tel Louis de Boisredont. Il s'agira donc non seulement d'identifier ces hommes d'armes, artisans ou clercs mais surtout de comprendre les raisons de leur présence aux côtés du maréchal. Dans un second temps, nous nous intéresserons à la pratique de la guerre qui fut celle de cette troupe, dans un terroir qui était presque parfaitement étrangers aux usages de la « guerre anglaise ». Comment celle-ci se définissait-elle et quelles furent ses originalités ? Il importera également de constater en quelle mesure celle-ci a pu peser sur les dernières années que Jean Le Meingre passa à combattre en France, et notamment sur son plan de bataille dressé à la veille de la bataille d'Azincourt. Cette communication tirera un grand profit non seulement des chroniques italiennes et des dépêches diplomatiques qui se firent l'écho de cette campagne mais surtout d'un document d'archive d'une valeur exceptionnelle, le compte KK 40 des Archives nationales, composé sur ordre de Boucicaut au lendemain de son retour en France en vue de se faire rembourser par Charles VI l'argent qu'il avança pour l'entretien de son armée. Celui-ci se trouve au cœur de nos recherches actuelles puisque nous travaillons actuellement à son édition qui, nous l'espérons, pourra être achevée et publiée au cours de l'année 2016. [less ▲]

This paper deals with Caryl Phillips, a contemporary British author of Caribbean descent, whose work, both fiction and non-fiction, testifies to his interest in music, both thematically and formally: countless references to music can be found in the titles of his books, in scenes involving musical performances, in the use in the narrative of musical terminology, but also in intriguing structural analogies with musical forms. My proposal is to analyse the influence of music in Phillips’s novel Crossing the River (1993; London: Vintage), which has been described as his most jazzy text. Very much like jazz -- which is for the Barbadian poet Edward Kamau Brathwaite “a cry from the heart of the hurt man”-- Phillips’ writing gives a voice to the victims of history, to shattered individuals in pain whose tragic fate is viewed at once as personal and collective. The novel not only illustrates the thematic overlaps between his narrative and the issues addressed in the lyrics of the African American musical tradition, such as discrimination and family disruption, but also exemplifies the author’s formal musical influence through the recurrent and creative use of meaningful variations in rhythm and of repetitions, which are again focal constituents of jazz. Throughout the novel, especially in the sections framing the narrative, the continual modulation of purposeful words such as “listen”, the variation of rhythm through punctuation and stressed/unstressed syllables, the reiterated elements, create a sonic pattern that goes over and over in the readers’ mind. My contention is that Phillips’ musical language crucially contributes to the emotional impact of his lyrical prose, which generates in the readers mixed feelings of sympathy and disorientation and prevents them from forgetting the characters’ stories which resonate long after closing the book.

Cette communication s’appuie sur les résultats issus d’une recherche menée dans une entreprise européenne du secteur des télécommunications, portant sur le travail à distance. Elle valorise en particulier les apports des travaux de Goffman dans l’analyse de ce phénomène, tant sur le plan méthodologique que sur le plan de l’analyse. Dans le cadre de cette étude, l’équipe de recherche a élaboré une méthodologie d’observation multifocale, visant à cerner certains aspects du travail à distance généralement oblitérés par la littérature, essentiellement basée sur des pratiques déclaratives. Le recours à cette méthode d’observation permet ainsi de mettre en évidence des stratégies d’interaction mises en place par les acteurs à distance, choisissant de rendre visibles ou, a contrario, de maintenir cachées certaines attitudes lors d’interactions à distance. Par ailleurs, la mobilisation du concept de cadres de l’expérience, au coeur des travaux de Goffman, met également en évidence deux enjeux pour lesquels les différents cadrages d’une même situation influence la perception de dispositifs RH. Les résultats obtenus enrichissent l’appréhension des dispositifs de gestion du travail et du management à distance, en intégrant la compréhension et l’expérience qu’ont les acteurs des dispositifs ainsi que la manière dont ils se les approprient.

The impact of environmental changes on the emergence and dispersal of anatomically modern humans (AMH) is particularly important in North Africa, since the Straits of Gibraltar might have served as western migration route for AMH from Africa to Europe. The prehistoric rock shelter of Ifri n’Ammar in NE Morocco reveals discontinuous Middle and Late Palaeolithic occupation phases since ~170 ka. Our study focuses on Wadi Selloum deposits to unravel palaeoenvironmental features and geomorphological aspects of the direct vicinity of Ifri n’Ammar. As a tributary of the Moulouya River, the catchment area of this ephemeral stream amounts to ~290 km², spanning elevations between ~700 and 200 m above sea level. Headwaters of the 35 km long Wadi Selloum drain Mesozoic limestone and dolomite. The application of luminescence dating techniques on Wadi Selloum deposits yielded burial ages between 1.3 ± 0.2 ka and 78 ± 7 ka, covering morphodynamically stable and active phases. Overbank fines include well-developed soil horizons as evidence of stability and of more humid periods than today around 80 ka and during the Holocene. This is supported by pedofeatures discovered in thin sections as well as the composition of clay minerals of the wadi sediments. Disordered clay minerals and partly illite/chlorite mixed-layer characterize the soil levels. Levels relatively rich in chlorite, illite, ankerite and quartz are interpreted as corresponding to relatively dry periods, while more humid periods lead to more intensive weathering and consequently to the dominance of clay minerals more advanced in the relative stability scale, such as kaolinite. Smectite is taken to indicate a climate with contrasting seasons and a pronounced dry season. In contrast, coarse-grained deposits, which are partly characterised by calcrete layers, point to drier conditions after 80 ka and 14 ka. In addition, the lack of palaeosols confirms morphodynamic activity during these periods. Acknowledgement.

Most of recent anthologies on architectural theory concede that the encounter between architects and the derridean philosophy of deconstruction has marked a kind of turning point in our architectural practices (Sykes, 2010; Mallgrave, Goodman, 2011; Greig, Cairns, Heynen, 2012). Yet this specific episode of our late history seem still provoke a kind of discomfort in the French-speaking part of the contemporary architectural debate. It is as if no one could take on what this disciplinary crossing of the mid-eighties both has produced and has not succeeded in producing. So now, thirty years later, how to be the heirs of such a theoretical experiment? “Inheritance is never a given; it is always a task. It remains before us” (Derrida, 1994). The present paper will attempt to develop what is at stake in the question of the inheritance of deconstruction in architecture. But if inheritance is a “task”, the concern is not here to simply describe it but to take on this task; the concern is to take part at the always ongoing building of this theoretical inheritance. Based on a thesis research still in progress, the paper will present some of the methodological experiments (Despret, 2001) set up in order to build an inheritance for deconstruction in the French-speaking part of architectural debate, and more specifically the original French translation of Wigley's essay, “The Architecture of Deconstruction: Derrida's Haunt”. The translation is here to be understood as an artifact from which new ways to inherit this historical turning of architectural theory can be built. But how to build such an inheritance in a way that doesn't erase its contradictions? And what does it mean to build it today ? The entire methodological apparatus of this attempt of translation will be display as a speculative process, considering theory as a living material for architectural creation. [less ▲]

In this paper we focus on how models carry out correlations and how correlations are used as techniques of government. Correlations are fragile exercises which put together two phenomenon, e.g. one nanoparticle and one toxic effect, without linking them with a straight causality. We examine correlations in the situated case of QSAR (quantitative structure-activity relationship) models applied to the toxicity of nanoparticles. Using scientific and regulatory documentation related to QSAR, and the preliminary results of an empirical study of a QSAR project conducted in France, we analyze the initial expectations, i.e. providing knowledge on nanoparticles useful for regulatory purposes, and how this ambition was confronted to the refusal of nanoparticles to feed the QSAR models in a satisfying way. We argue that this led to "thinking on the edge" the wonders and worries of correlation. This calls for a pragmatics of correlation: what does it do? Which are the effects and consequences of a "co-relating" approach? Exploring these questions leads us to examine the type of knowledge produced through models applied to large sets of data, and how it contributes to certain types of regulatory objectivity, particularly in the European legal context. Thus, we discuss the ways in which a pragmatics of correlation offers analytical entry points for the study of the contemporary transformation of the public administration of technical objects.   [less ▲]

It is widely accepted that cell fate determination in the cochlea is tightly controlled by different factors that remain to be fully defined. Here, we show that Sox9, initially expressed in the entire sensory epithelium of the cochlea, progressively disappears from differentiating hair cells (HCs) and is finally restricted to supporting cells (SCs). The absence of Sox9 leads to supernumerary HCs production, and its overexpression blocks HCs differentiation even if co-expressed with Atoh1, a transcription factor necessary and sufficient to induce HCs. Sox9 reduces Atoh1 transcriptional activity by upregulating Hey1 and HeyL factors and genetic ablation of these genes induce extra HCs along the cochlea. Furthermore, we show that Sox9 is required for Notch-dependent inhibition of HC fate. Taken together, these data show that Sox9 contributes to Notch-dependent cochlear cell patterning by upregulating Hey1 and HeyL proteins in future SCs, thereby preventing Atoh1 from driving HC differentiation.

Stimuli-responsive nano-materials have been playing increasingly important roles in the biomedical field due to their ability to adapt their physico-chemical properties in response to external stimuli, such as temperature, pH, ionic strength, magnetic field, etc. Nanohybrids combining inorganic particles and stimuli-responsive polymers are particularly well-suited to develop advanced drug nanocarriers for targeted delivery and concomitant diagnostics. Based on the recent developments in controlled radical polymerization, especially cobalt-mediated radical polymerization, various hybrid nanostructures have been synthesized and tested as drug delivery systems able to trigger the drug release in response to dedicated environment conditions or external stimuli. Studies on cytotoxicity, cellular uptake and in vitro triggered release with cell culture will also highlight the potential of these new materials. [less ▲]

Anxiety sensitivity (AS) is defined as the fear of anxiety-related sensations due to the belief that these sensations could lead to harmful physical, psychological or social consequences. Some authors examined the contribution of parental factors to child's AS. However, little is known about the relation between parental anxiety and child’s AS, particularly in non-clinical samples. AS being an important risk factor in anxiety, it seems important to understand how AS develops without existing psychopathology in order to act preventively. Moreover, another concern is the little consideration of father, most studies having investigated mother's contribution. This study examined the contribution of mothers’ and fathers’ anxiety to the development of four dimensions of AS in children: physical concerns, mental incapacity concerns, social concerns and losing control concerns. Our sample included 200 non-clinical Belgian children (105 girls) aged 9 to 13 years, 200 mothers and 200 fathers. Children completed the Children Anxiety Sensitivity Index (CASI) whereas parents completed the State-Trait Anxiety Inventory (STAI). The regression analysis revealed that mother and father’s anxiety significantly predicted child’s AS, but in a different way. Mother’s anxiety was positively associated with physical concerns (b = .06, p = .015) and mental incapacity concerns (b = .03, p = .020). Father’s anxiety was negatively associated with physical concerns (b = -.06, p = .018) and losing control concerns (b = -.03, p = .020). Women appear to express their anxiety with more intensity and to be more concerned with the unpleasant emotional, physical, and mental experiences of anxiety while men seem to express their anxiety with less intensity and more control. Without existing pathology, mothers and fathers could thus propose a different model of expression of anxiety symptoms. These gender differences, when observed by children, could lead different beliefs about consequences of anxiety-related sensations. [less ▲]

Burundi: The teaching and learning of French returnees students Summary of the report 1965, 1969, 1972 and from April 2015 1988.1993 alas, Burundi lives recurrently a political-ethnic violence spiral that claimed the lives of hundreds of thousands of Burundian and forced into internal and external exile more one million Burundi. Since 2006, most of these exiles began returning voluntarily, while others are forcibly evicted from Tanzania to neighboring provinces of Burundi. In total, 478 865 people have been repatriated since 2002 and 95.068 in 2008. And since August 2013, following the political tensions between Rwanda (northern Burundi) and Tanzania (east and southern Burundi) 10,000 5à Burundi refugees were forcibly repatriated a week. People in school age integrate the education system in place where French is a language taught and teaching language. It was initiated in classes, intercultural dialogue of languages and cultures in contact between students who speak Swahili and English on one hand and on the other hand their hosts who speak Kirundi and French elementary level. However, resistors extending to verbal or physical violence are seen following their remoteness of linguistic realities of their migratory journey To achieve the objectives of social inclusion and school integration strategies have been implemented to allow newcomers to develop a practice more or less adequate French. Cultural sessions with spontaneous participation and freedom to use the language they master the most (French, English, Swahili and Kirundi) facilitated the initiation of a synergy in training in French with other languages of the course migration of our learners Based on a work tool, basic lexicon in four languages taught in Burundi in 2011 funded a priority solidarity fund for French cooperation I introduced theatrical improvisations activities such as motivational tools and learning about living together and reconciliation and for the personal development of learners pleasure of learning French and to learn French we have prepared and performed a sequence on reconciliation Patrice Faye and each repetition was , simultaneously, subject to a French lesson . This was a source of cohesion among our learners. The motivation was strengthened and despite their learning difficulties and communicate a positive report to the French language has gradually developed and installed. Note , for all practical purposes, a dramatic decision in 2006 , months after the end of a terrible war , was to install the compulsory teaching of languages in the first four primary year to a student population of six years following a 90% rural population . This was to teach simultaneously Kirundi (L1) , mother tongue, French (L2 ), English (L3) and Kiswahili (L4) , widespread language in the neighboring States. This measure was the subject of a scientific and political debate it is easy to guess. This issue has , subsequently made subject of my thesis project title ; " Burundi : The teaching and learning of French to college kids repatriated from Tanzania and the East of the DRC .Profils language , school conditions and educational proposals" Burundi : L’enseignement et apprentissage du français aux élèves rapatriés Résumé de la communication 1965, 1969, 1972, 1988,1993 et depuis avril 2015 hélas, le Burundi vit de manière récurrente une spirale de violences politico-ethnique qui a emporté la vie des centaines de milliers de burundais et contraint à l’exil intérieur et extérieur plus d’un million de burundais.

Et depuis août 2013, suite aux tensions politiques entre le Rwanda (au nord du Burundi) et la Tanzanie (à l’Est et sud du Burundi), 5à 10.000 réfugiés burundais étaient rapatriés de force par semaine . Les personnes en âge scolaires intègrent le système éducatif en place où le français est une langue enseignée et langue d’enseignement. Il s’agissait d’initier, dans les classes, un dialogue interculturel des langues et cultures en contact entre les élèves qui parlent le swahili et l’anglais d’une part et d’autre part leurs hôtes qui parlent le kirundi et un français de niveau élémentaire. Cependant, des résistances allant jusqu’aux violences verbales voire physiques s’observent suite à leur éloignement des réalités linguistiques de leur parcours migratoire. Afin de réaliser les objectifs d’insertion sociale et d’intégration scolaire, des stratégies ont été mises en œuvre pour permettre aux nouveaux arrivants de développer une pratique plus ou moins suffisante du français. Des séances culturelles avec une participation spontanée et liberté d’utiliser la langue qu’on maîtrise le plus (français, anglais, swahili et le kirundi ) ont facilité la mise en route d’une formation en français en synergie avec les autres langues du parcours migratoire de nos apprenants en nous basant sur un outil de travail, Lexique de base en quatre langues enseignées au Burundi,2011 financé par un fonds de solidarité prioritaire de la coopération française . J’ai introduit des activités d’improvisations théâtrales, comme outils de motivation et d’apprentissage, sur le vivre ensemble et la réconciliation, puis, pour l’épanouissement personnel des apprenants au plaisir d’apprendre en français et d’apprendre le français, nous avons préparé et joué une séquence sur la réconciliation de Patrice FAYE et chaque répétition faisait, en même temps, objet d’une leçon de français. Ceci a été une source de cohésion entre nos apprenants. La motivation s’était renforcée et malgré leurs difficultés d’apprentissage et de communiquer, un rapport positif à la langue française s’est peu à peu élaboré et installé. Notons, pour toutes fins utiles, qu'une décision spectaculaire prise en 2006, quelques mois après la fin d'une épouvantable guerre, était d'installer l'enseignement obligatoire de quatre langues dès la première année du primaire, à une clientèle scolaire de six ans issue d'une population à 90 % rurale. Il s'agissait d'enseigner en même temps le kirundi (L1), langue maternelle, le français (L2), l'anglais (L3) et le kiswahili (L4), langue répandue dans les États voisins. Cette mesure a été l'objet d'un débat scientifique et politique qu'il est aisé de deviner. Cette question a, par la suite, fait objet du titre mon projet de thèse ; « Burundi : L’enseignement et apprentissage du français aux jeunes collégiens rapatriés de Tanzanie et de l’Est de la RDC .Profils linguistiques, conditions scolaires et propositions didactiques » [less ▲]

In 1984, introducing a new section of Les Cahiers de la bande dessinée, Pierre Sterckx coined the concept of “case mémorable” (remembered panel) to refer to specific comics panels remembered from childhood reading because of their visual effect. The idea of a case mémorable, however, was not only a cognitive concept: it implied an active remembrance, as the magazine section urged readers to send in their analyses of their own remembered panels. It consisted in an intimate act of canonization based on the collective sharing of a personal history of comics. As Sterckx wrote, the case mémorable is “an atom of comics history.” French cartoonists Blutch and Olivier Josso Hamel have put the concept to fruitful uses in their autobiographical work, coupling the remembrance of their childhood to that of their reading experiences. This paper focuses in particular on Josso Hamel's Au travail, sketching out how the author represents an anti-narrative reading experience, projecting his own experiences onto the albums, reshaping their narratives along other axes. Redrawing these panels further compels the artist to reinvent his own graphic style. In this sense, Josso Hamel portrays what it means to remember and possess an image, raising compelling questions not only about quotation and appropriation but also about the relation between the single image and the narrative sequence, which are examined under the light of comics theory (Baetens, Marion) and film studies (Burgin, Mulvey). Through the analysis of Josso Hamel's bande dessinée, this paper revisits Sterckx's concept of the remembered panel as a citational practice loaded with memory-making effects. [less ▲]

Apparue au 18e siècle, la piste, dont la forme circulaire est idéale pour faciliter l’équilibre des cavaliers qui profitent de la force centrifuge, devient rapidement l’un des éléments définitoires de l’esthétique circassienne tout en s’offrant comme l’une des nouvelles composantes normatives du spectaculaire. Depuis, si le cercle est par excellence l’espace de représentation du cirque, il semble pouvoir représenter aussi pour le cinéma une source d’inspiration dans le cadre du renouvellement perpétuel d’une conception de la mise en scène favorisant les effets d’immersion et d’attraction. À travers l’évocation de différents exemples issus de l’histoire du cinéma, avec un focus particulier sur le cinéma stéréoscopique contemporain, et notamment la série très populaire des films de danse de la franchise Step Up (2006-2014) dont les trois derniers opus ont été exploités en 3-D, cette communication s’intéressera aux effets d’immersion, de jaillissement et de volumétrie permis par la restitution de performances corporelles saisies dans un espace simulant la tridimensionnalité et travaillé par les dynamiques du concave et du convexe.

Sharing digital textual resources is an actual challenge for scholars working on Ancient Egyptian-Coptic (3000 BC-1350 AD). There are two types of reasons for this: first, the different writing systems that have been used throughout the history of this language (hieroglyphic and hieratic scripts, demotic, Coptic) led to various solutions as regards the encoding of texts; second, the diverging aims and scopes of the projects involved in creating annotated corpora of Ancient Egyptian-Coptic generated representation formats with few characteristics in common. As a result, the resources themselves cannot be shared, and no standard tool can be used for encoding, annotating, querying or analyzing these resources. In order to overcome these issues, several leading projects in the field join forces and introduce a TEI compliant interchange data model that has the following characteristics: 1) The ancient Egyptian-Coptic TEI interchange data model represents an agreement on a subset of the EpiDoc schema towards which the textual data of each project can be converted. Project specific annotations are dealt with either using stand-off markup that refers to tokens of transliterated texts (Bański 2010; Pose et al. 2014), or on the basis of data models that are true expansions of the kernel interchange data model. 2) The specialized metadata elements and attributes referring to Egyptological concepts are based on controlled vocabularies that are shared and enriched collaboratively by the projects. 3) These metadata apply either to physical text-bearing objects, inscribed physical features, witnesses (on documents) or texts (Morlock & Santin 2014). As the conceptualization of the relationship between these entities is shared between projects, coherence and precision when describing both the material, philological and linguistic dimensions of textual resources can be obtained.

Land use and land cover (LULC) maps are important tools for the management of the environment, in particular for the modelling of biogeochemical cycles and climate. LULC maps are typically produced using supervised classification of satellite images supported by expert knowledge. Nowadays, the advance of the crowdsourced project OpenStreetMap (OSM) offers an alternative to official LULC maps. In OSM, LULC is usually mapped by manual digitalisation of satellite imagery and/or by the import of existing databases. We explored the potential of OSM to contribute to the improvement of an existing LULC map, Corine Land Cover (CLC), by comparing forest cover in Southern Belgium and Luxembourg. We focused on three forest types that were common to the two databases: coniferous, deciduous and mixed forest. Confusion matrices showed that the two databases differed in terms of classes over about one quarter of the forest area. Moreover, 9.9% and 8.0% of the forest area in OSM and CLC, respectively, were unmapped as forest area compared to the other database. Compared to CLC data, small patches of forest areas are mapped in OSM data. This study is a first attempt to show the potential of a crowdsourced project, i.e., OSM, to contribute to an official geodatabase. While current drawbacks of OSM such as the lack of completeness may limit its application in some operational applications, we claim that its large accessibility and its potentially high reactiveness makes OSM a serious alternative to existing geodatabase.

In this talk, I will first recall basic results on binomial coefficients of words, then review the connections and differences with Parikh matrices. As a generalization of abelian equivalence, two words u and v are k-binomially equivalent if every word of length at most k appears as a subword of u exactly as many times as it appears as a subword of v. So a k-binomial square is a word uv where u and v are k-binomially equivalent. We will discuss avoidance of squares and cubes in infinite words (this is a joint word with M. Rao). Finally, I will consider the question of deciding whether or not two finite words are k-binomially equivalent. This problem has recently been shown to be decidable in polynomial time by Freydenberger, Gawrychowski et al. [less ▲]

In the current energy context, many efforts are devoted to the reduction of the energy footprint of buildings. To meet this challenge, the LCIS-GREENMAT laboratory developes a front edge research in the field of advanced materials associated to energy and environment, including structured materials for dye-sensitized solar cells (DSSCs) and electrochromic coatings. DSSCs have been reported by O’Regan and Grätzel in the early nineties as a very promising alternative to conventional photovoltaic silicon devices. Main benefits of these cells are their low cost as well as their mild manufacturing process. In most of the specific literature, DSSCs are made of TiO2 films prepared by doctor-blade or screen-printing of anatase nanoparticles paste. However, due to the random organization of the nanoparticles, pore accessibility by the dye and electrolyte could be incomplete. Moreover, some anatase crystallites could suffer from a lack of connectivity, leading to electron transfer issues. The strategy adopted by our group to improve photovoltaic efficiencies involves a templating-assisted process to prepare highly porous layers with well-ordered and accessible pores as well as improved crystallites connectivity. This talk especially focuses on the templating-assisted synthesis of TiO2 and ZnO semiconducting layers used as photoelectrode in DSSCs. Due to the surface area improvement as well as the perfect control of the pore organization and the pore size, the templating strategy is an effective solution to maximize the adsorption of active dye and the electrolyte infiltration inside the porous network. Besides, in the last few years, there has been increasing interest in electrochromic glazing due to its potential use as an energy-efficient component for buildings, as it could reduce considerably their CO2 emission by decreasing their energy consumption up to 30%. The crucial issues of such devices are the durability, the coloration efficiency and the reversibility upon coloration and bleaching of the electrochromic layers. In order to improve the performances of those electrochromic films, we have investigated a surfactant-assisted deposition process for WO3 layer and the insertion of lithium in the NiO layer. All films have been deposited on FTO glass substrates by ultrasonic spray pyrolysis (USP), which is a low-cost alternative to industrial vacuum processes for manufacturing high quality thin films. The presence of lithium ions in nickel oxide films has shown improved coloration efficiency compared to the undoped films. The higher active surface of surfactant-assisted tungsten oxide films has led to higher reversibility and coloration contrast. [less ▲]

HOME BLOOD PRESSURE IN KIDNEY TRANSPLANT RECIPIENTS (KTR)-Validity of different schedules of self-monitoring A. Saint-Remy, L. Weekers, C. Bonvoisin, P. Xhignesse, B.Dubois, JM. Krzesinski NEPHROLOGY - CHU LIEGE AIM: Office blood pressure (OBP), 24-h ambulatory monitoring (ABPM) and home self- monitoring (HBP) allow assessing BP control in treated HT patients. For HBP, ESH guidelines recommend 7 days of measurements but that duration is questioned. The present study analyzed the agreement between daytime ABP and different schedules for HBP in 70 treated hypertensive KTR. METHOD: BP control defined by OBP <140/90 and daytime ABP or HBP <135/85 mmHg was tested in 70 KTR (mean age 56 ± 11 y; mean graft survival 7 ± 6.6 y). OBP and HBP were measured with an Omron M6 and 24-h ABPM with a Spacelabs 90207. HBP was measured on consecutive days (2 times in morning and 2 times at evening/day), the first day was discarded for the mean calculation. Agreement between daytime and HBP was studied when HBP was measured during 7, 5 or 3 days. RESULTS: BP was uncontrolled in 50% of the KTR based on OBP, in 61 % according to daytime ABP and even in 64 % with HBP. Sensitivity (Se) testing agreement between daytime ABP and HBP decreased progressively when number of days was shortened: the highest Se was observed for a 7 days duration with 1st day discarded (86 %). Specificity (Sp) fluctuated around 70 % and was the highest for a 5 (73 %) and 3 days schedule. However the 5 days schedule had higher Se (83 %) than the 3 days. Proportions of KTR correctly classified according to daytime ABP were 79 %, 79 % and 78 % with the 7, 5 or 3 days schedule, respectively. CONCLUSIONS: HBP, easier and less restricting method than 24h ABPM, is a good alternative to daytime ABPM as nearly 80 % of treated KTR were similarly classified. HBP recording period can be shortened to 5 days according to Se and Sp. A 3 days schedule seems more risky reducing the chance to identify masked HT due to a decreased drug adherence. [less ▲]

For the 10 last years, terrestrial and satellite (GRACE) gravity measurements have reached such a precision that they can be of interest to better monitor underground water masses. First, we show that terrestrial measurements provide high-precision information about the time evolution of mass changes in the few kilometres square around the gravimeter. Then, examples of the possibilities and limitations of terrestrial measurements are given in Membach, close to Eupen, and in the Rochefort karst system. In Membach, we show that the evapotranspiration can be directly inferred from continuous gravity measurements: as water evaporates and transpires from terrestrial ecosystems, the mass distribution varies through the system, changing its gravity field at the level of, or smaller than 10-10 g per day. This corresponds to 2.0 mm of water over an area of 50 ha. The strength of this method is its ability to ensure a direct, traceable and continuous monitoring of actual ET for years at the mesoscale (~50 ha) with a precision of a few tenths of mm of water. In Rochefort, gravity measurements at the surface and in the cave allows separating the water contained in the unsaturated zone from the saturated one and therefore monitoring groundwater content changes that occur in the unsaturated zone only.

Perinatal brain injury is a major contributor to neonatal morbidity and mortality and is a common cause of disability with devastating impact on individuals and families. The mechanisms involved in the genesis of brain lesions depend of the the gestational age at which brain development is altered. In the term infant, the most common pathology implicated in brain damage is hypoxic-ischemic encephalopathy (HIE). HIE is the consequence of an excitotoxic cascade leading to cortical and/or basal ganglia lesions. Therapeutic hypothermia induced in the 6 hours following HIE reduces the risk of death or major neurodevelopmental disability in the neonate with moderate or severe encephalopathy and is the only neuroprotective treatment available in clinical practice. Research is now being focused on other promising strategies such as xenon, allopurinol, N-acetyl cystein, melatonin, anticonvulsant, erythropoietin or stem cell transplantation. In the preterm infant, diffuse white matter injury (dWMI) is the main pathological condition associated with neurological impairment. Based on experimental models, pathophysiological mechanisms of dWMI potentially include infection/inflammation, hypoxia-ischemia and oxidative stress. Experimental studies suggest a sensitizing effect of systemic inflammation that makes the perinatal brain more vulnerable to further insults. Antenatal magnesium sulfate therapy given to women at risk of preterm birth substantially reduced the risk of motor disorders in childhood but is unfortunately unable to reduce long term cognitive impairment or behavioural disorders. Antenatal steroids and caffeine therapy for apnea of prematurity are two other treatments with positive impact on neurodevelopment. Randomized controlled trials studying erythropoietin or melatonin are currently under process. Finally, research performed at the University of Liege suggests that Estetrol (E4), an estrogen synthetized exclusively by the human foetus, has neuroprotective properties in animal models of HIE as well as in inflammatory-induced dWMI.

A pseudo-Boolean function is a real-valued function of 0-1 variables. Every pseudo-Boolean function can be represented by various analytical expressions, e.g., as a polynomial in its variables, or as a polynomial in its variables and in their Boolean complements, or as a disjunctive form, or as pointwise minimum of a family of affine functions, and so forth. Motivated by the problem of minimizing pseudo-Boolean functions, we consider yet another class of representations. Namely, we say that g(x,y) is a quadratization of the pseudo-Boolean function f(x) if g(x,y) is a quadratic pseudo-Boolean function of x and of m auxiliary binary variables y such that, for all x, f(x) = min g(x,y), where the minimum is taken over all possible values of the y-variables. It can be shown that every pseudo-Boolean function has at least one, and usually, many quadratizations. In recent years, several authors have proposed to reduce the problem of minimizing an arbitrary function f(x) (say, expressed as a high-degree polynomial) to the (presumably easier) problem of minimizing one of its quadratizations. In this talk, we discuss the size of ``small'' quadratizations, that is, the number of auxiliary variables required in any quadratization. We provide lower and upper bounds on the number of auxiliary variables for the case of an arbitrary function f(x), as well as for the special case where f(x) is a symmetric function of its variables.

Indeed he found what he thought to be the proof of the Liège Renaissance Master’s intervention in the painting of the Saint Denis Altarpiece panels, before giving up the attribution in 1970. Since then, these two mentions have been used to illustrate either the involvement of Lombard or of another painter named “Lambert” in the painting of the panels. But looking closer at the original document, it is obvious that Yernaux committed huge mistakes in the transcript of these mentions. Not only was he wrong about the sums paid to the artist but also about the work mentioned in this account. In order to understand this document fully and correctly, it is therefore essential to propose a transcription from which new interpretations can be generated. This new understanding can then lead to further contextualization of the mentions. These accounts need to be looked at in close relationship with the rest of the document. This would shed new light on the writer’s habits, especially when it comes to designate individuals. The amount of money given to the painter Lambert also needs to be assessed. Comparisons to other payments of the same period conserved in the archives of the Saint Denis church and of other churches in or around Liège are going to be unveiled and investigated. This will give interesting clues to understand better the extent of the work done by the artist as well as his social status. [less ▲]

Les spécificités et les difficultés de la « lecture pour apprendre » au début du secondaire sont à l’origine du projet de recherche longitudinale de type quasi-expérimental dans lequel s’inscrit notre contribution. « Lirécrire pour apprendre » a pour principaux objectifs d’expérimenter, durant deux années successives (2014-2016), un programme didactique centré sur le développement de la compréhension et de la production des textes à visée informative-explicative ; de tester la valeur de cet outil sur un large échantillon d’élèves du premier degré de l’enseignement secondaire et d’évaluer les conditions d’implémentation et de mise en œuvre de l’outil les plus favorables au changement de pratiques pédagogiques et au maintien de l’innovation. Dans le cadre de cette contribution, à l’issue de la première année de l’expérimentation, nous évoquons quelques éléments de définition et de modélisation préalables (première partie), quelques-uns des constats posés en amont de la conception du programme (deuxième partie) ainsi que le design de la recherche et les caractéristiques du dispositif didactique (troisième partie). Ces éléments constituent le cadre de référence dans lequel s’inscrit l’étude développée dans la quatrième partie du texte, relative aux premiers résultats quantitatifs de l’expérimentation du dispositif. Les données recueillies auprès d’un échantillon de 1690 élèves (scores bruts), limitées aux apprentissages en lecture, sont examinées à la lumière de la question suivante : les élèves peuvent-ils, sous l’influence d’un outil structuré, progresser dans leur capacité à comprendre un texte ou un dossier de documents informatifs-explicatifs et à rendre compte de leur compréhension ? Seule l’évolution des performances des élèves est ici étudiée. Deux autres variables prépondérantes, qui influencent les résultats des élèves, à savoir l’appropriation de l’instrument didactique par les enseignants ainsi que les pratiques effectives d’enseignement, seront analysées ultérieurement, à la lumière de l’ensemble des données de la recherche.

Dans les matériaux de construction, la notion d’environnement et d’empreinte des produits devient de plus en plus importante que ce soit dans un cadre législatif ou comme objet de marketing. Dans ce contexte, des études environnementales ont été réalisées sur divers produits belges en pierre bleue (dalles, bordures, marches) ainsi qu’en grès (pavés). Ces études ont été menées en utilisant la méthodologie de l’Analyse du Cycle de Vie (ACV) et ont permis de mettre en évidence les étapes prépondérantes de leur production dans une optique d’écoconception ainsi que de les comparer à d’autres produits sur le marché tels que leurs concurrents asiatiques. Les frontières du système comprennent les étapes depuis l’extraction des matières premières, en passant par la production des produits finis ainsi que leur transport sur chantier situé en Belgique. Cette présentation reprend le pourquoi et le comment d’une Analyse du Cycle de Vie, les différentes étapes nécessaires à l’application de l’ACV aux produits en pierre belge ainsi que les principaux résultats. Cette présentation permettra la mise en évidence de l’intérêt de l’ACV et des fiches de déclaration environnementale qui y sont associées ainsi que les perspectives qui peuvent en découler dans le domaine des matériaux et plus précisément pour les matières minérales.

Paraneoplastic hypercalcemia and hypercalcemia associated with neoplastic syndromes are particularly resistant to conventional hypocalcemic treatments. We present and discuss two case reports in which Cinacalcet was used to control hypercalcemia. Paraneoplastic hypercalcemia is present in the first case report, in association with a metastasic neuroendocrine pancreas. In the second case report ,cinacalcet is used to control hypecalcemia in a patient with multiple endocrine neoplasia and hyperparathyroidism not controlled by neck surgery. Cinacalcet is an oral agonist of the Calcium Sensing Receptor. The hypocalcemic effects of Cinacalcet have not been documented so far in hypercalcemia-paraneo plastic linked to cancer of the pancreas (Valdés-Socin & al. Rev Med Switzerland 2009). On the other hand, its use seems promising in the MEN1-associated hyperparathyroidism. (Giusti & al. Endocrine 2015). [less ▲]

This paper investigates the impact of corporate board of directors’ (supervisory) attributes on conditional accounting conservatim in the French, German and British contexts. Using pooled regression model over the period 2009-2012, our findings report that the relationship between corporate board attributes and accounting conservatism is country dependent. First, regarding the board composition, we find that the effect of board size is positive for German firms, negative for French firms and insignificant for British firms. We also document a positive association between board independence and accounting conservatism for British firms. However, we find no evidence of a positive association between employee seats on the supervisory board and earnings conservatism in German context. Second, female seats on board seem to increase conservative reporting in financial statement only for French firms. Lastly, board meeting frequency in French and British firms appears to increase accounting conservatism. As a robustness test, we use an alternative measure of accounting conservatism namely, time–series of earnings changes measure and confirm the previous results. Overall, our results reveal that corporate board affects the financial reporting quality. [less ▲]

Despite growing recognition that the technical and social dimensions of technology development are coproduced, research and policymaking in the nuclear field is still predicated on the separation between both dimensions. This paper explores how this separation is enacted, and occasionally questioned and transformed, within the Belgian context of nuclear technology. It situates the emergence of a science policy support (SPS) unit and programme (PISA) within the Belgian Nuclear Research Centre SCK•CEN as an institutional response to the need of integrating societal and ethical concerns into nuclear research. The paper elicits how since 1999, SPS/PISA draws together science and technology studies (STS) and technology assessment (TA) approaches, creating links between nuclear research innovation and society in mutually beneficial ways. To this end, it first outlines the four areas in which SPS/PISA researchers are active: 1. Ethics of nuclear technology assessment; 2. Radioactive waste management; 3. Safety governance; 4. Perception and communication of ionising radiation risks. As SPS/PISA research is situated in a trading zone that embeds scholarship, nuclear research and research policy, the paper illuminates the growing entanglement of the natural and social sciences, and the roles social scientists play in the development of contemporary technologies and technology policy. Drawing on the notion of hybrid management (Miller 2001), the paper argues that SPS/PISA researchers must develop a language that underlines the interdependency between science, policy, and politics, while acknowledging that actors (policymakers, industry representatives, natural and social scientists, citizens) recurrently draw distinctions between these domains as a means of collectively managing nuclear issues. SPS/PISA research is therefore best understood as boundary work that mediates between various interests, values, and "knowledges." The paper concludes by discussing the key challenges SPS/PISA researchers face while engaging in work of this kind: maintaining professional independence and credibility, ensuring research continuity, and generating both scientific and policy impacts.

Biopreservation is the use of naturally occurring microorganisms and/or their inherent antimicrobial compounds to extend shelf life and to enhance the safety of foods. The aim of the present study was to perform a sensory evaluation of beef patties inoculated with potentially biopreservative strains of Carnobacterium maltaromaticum. Three different strains of C. maltaromaticum (lab. ref.: CM_824, CM_827 and CM_829) isolated from vacuum packaged beef with long shelf life were selected for this study. An untrained panel was requested to make a sensory evaluation of raw and cooked beef patties 8 and 10 days after inoculation with the selected strains at 104 and 106 UFC/g and storage in high-O2 atmosphere. After 8 days of storage, non inoculated samples (blank) were perceived as having the best studied sensory descriptors. The samples inoculated with strain CM_827 had a sensory quality very close to the blank. After 10 days of storage, samples inoculated with the strain CM_827 at 104 UFC/g received the highest scores for appearance and color. This study permitted to evaluate the effect of three C. maltaromaticum strains on the sensory quality of beef patties. Strain CM_827 did practically not change the sensory attributes of beef patties. Samples inoculated with strain CM_824 and CM_829 received the worst scores for several of the tested descriptors. Therefore, further research on the biopreservative capacity of C. maltaromaticum should be conducted with strain CM_827. [less ▲]
