This study is focused on Saadian ceramics called zellige from the archaeological sites of "El Badi palace" and "Saadian Tombs" (Marrakech, Morocco) dated in late 16th Century and classified as world heritage by UNESCO in 2008. A multi-analytical approach based on optical microscopy, cathodoluminescence, scanning electron microscopy, X-ray fluorescence and X-ray diffraction investigations and re-firing tests on ceramic supports has been used,in order to determineraw materials source, technical manufacturing and firing temperatures used by the Saadian artisans. Production technology, microstructure and the chemical compositionsuggest that the zellige pieces used in the construction of Saadian monuments in Marrakech are either imported from Fez, i.e. the main center of production of the zellige in Morocco, or manufactured locally in Marrakech according to the current standards and procedures in Fez. The calcareous clay raw materialwas used to manufacture these ceramics, but firing temperature was different. Zellige of El Badi palace was fired at a maximum temperature of 700°C in oxidizing atmosphere, while the one of Saadian Tombs was fired in the range 900-950 °C. The low firing temperature for Zellige facilitates the pieces cutting but it is responsible for the poor quality of these materials due to the absence of the vitreous phases. The results provide a scientific support for decision making in future conservation and restoration strategies of historical monumentsacross Morocco. [less ▲]

Advances in Computer-Aided Design and Manufacturing (CAD-CAM) composite materials and chair-side CAD-CAM systems offer a new landscape for the implant dentistry. Digital workflows are increasingly used, especially for single-unit restorations, and they allow straightforward and cost-effective protocols that improve patient satisfaction. The efficacy of immediate loading on single implants has been demonstrated (1, 2). Currently, to 12 promote osseointegration, the use of resin-based provisional crowns out of occlusion is recommended for immediate loading. Such protocols require several appointments and a significant contribution of the dentist and the lab technician, which affects overall treatment cost. On the other hand, CAD-CAM composites, especially Polymer-Infiltrated Ceramic Network (PICN), are now competing with ceramics for definitive single-unit restorations, notably due to their better machinability (faster and in lower-thickness milling, with les edge chipping) (3) (4), the absence of post-milling firing and the ease of in-mouth adjustments. In particular, their higher resilience and lower elasticity modulus could indicate them for immediate loading of implants. Intraoral scanning (IOS) of single-unit implants right after surgery and the chair-side manufacturing of a PICN crown would allow delivery of a resilient final tooth on the same day. The aim of these two case reports is to describe, as a technical note, an innovative approach for a straightforward and cost-effective replacement of a single missing tooth in the posterior region, as a proof of concept.

Worldwide, flood risk is expected to increase over the 21st century due to the combined effect of climate and land use changes. However, while the impact of climate change on future flood risk was extensively studied, the effects of urbanization remain unclear. The goal of this PhD thesis is to contribute to a better understanding of the influence of future urban development on changes in inundation flows as well as on the related damage. First, an original porosity-based model was developed, which enables efficient computation of urban flooding. It uses anisotropic porosity parameters to reproduce the influence of subgrid-scale obstacles on the flow. An original merging technique was implemented to optimize the computational efficiency in the presence of low values of the storage porosity parameter. Compared to a standard inundation model, the developed model enables speedup factors of the order of 100, while keeping the error on the flow variables at a few percent. Second, we systematically investigated how the layout of buildings located in floodplains influences the inundation characteristics for a long-duration flood scenario. The anisotropic porosity-based model was used to compute the flow variables for 2,000 alternative urban patterns. Correlations between the computed water depths and the urban characteristics reveal which features of the layout of buildings influences most the severity of urban flooding. In particular, the results suggest how the hydraulic effect of new urban development can be effectively mitigated by a suitable location of the buildings preserving a higher flow conveyance at the district-scale. This result provides guidance for more flood-proof urban developments. Finally, we evaluated the evolution of future flood damage as a result of urbanization along all the main rivers in the Walloon region, Belgium. The study was conducted at the regional level using detailed hydraulic results (resolution of 2 to 5 m). Despite high uncertainties in the considered urbanization scenarios, involving both urban expansion and densification, robust conclusions could be drawn, such as the overwhelming influence of banning new developments in flood-prone areas compared to the other tested facets of urban planning policy.

Vaccinia-H1 Related (VHR) dual-specificity phosphatase, or DUSP3, plays an important role in cell cycle regulation and its expression is altered in several human cancers. In mouse model, DUSP3 deletion prevents neo-angiogenesis and b-FGF-induced microvessel out- growth. Considering the importance of angiogenesis in metastasis formation, our study aimed to investigate the role of DUSP3 in tumour cell dissemination. Using a Lewis Lung carcinoma (LLC) experimental metastasis model, we observed that DUSP3-/- mice devel- oped larger lung metastases than littermate controls. DUSP3-/- bone marrow transfer to lethally irradiated DUSP3+/+ mice was sufficient to transfer the phenotype to DUSP3+/+ mice, indicating that hematopoietic cells compartment was involved in the increased tumour cell dissemination to lung tissues. Interestingly, we found a higher percentage of tumour- promoting Ly6Cint macrophages in DUSP3-/- LLC-bearing lung homogenates that was at least partially due to a better recruitment of these cells. This was confirmed by 1) the pres- ence of higher number of the Ly6Bhi macrophages in DUSP3-/- lung homogenates and by 2) the better migration of DUSP3-/- bone marrow sorted monocytes, peritoneal macrophages and bone marrow derived macrophages (BMDMs), compared to DUSP3+/+ monocytes, macrophages and BMDMs, in response to LLC-conditioned medium. Our study demon- strates that DUSP3 phosphatase plays a key role in metastatic growth through a mechanism involving the recruitment of macrophages towards LLC-bearing lungs. [less ▲]

In this work, materials have been produced by sol-gel route. This synthesis way has been used for immobilization on a support of a function focused on green chemistry. The different functions are related with different applications that allow to illustrate the versatility and the flexibility of this sol-gel process. The two applications are: - Photocatalysis: Synthesis of material with photocatalytic property or with an additional property - Cyclocarbonation: Synthesis of an immobilized catalyst for polyurethane production through a green process The first application concerns the use of a photocatalyst that allows to degrade volatile organic compounds (VOC). The main photocatalyst is TiO2. It has been studied as a powder or as a film deposited on a support. A comparison of these two shapes has shown that an identical photocatalyst can have different performances depending on the final shape. A catalyst must be considered in its totality and with its environment rather than as a chemical composition only. To increase the photocatalyst performances, modifications have been added as the Zn doping to increase the photocatalytic activity and the superhydrophilicity. These new photocatalysts have been compared with pure ZnO and bilayer films composed of TiO2 and of ZnO. Different photocatalytic tests have been performed and depending on the test the best photocatalyst was different. Then, to increase the economic interest, some dopant have been used. In addition of the improvement of the photocatalytic activity and superhydrophilicity, theses dopants add a new property such as electrical conductivity and anticorrosion. First, metallic silver has been incorporated to add antistatic property and to increase the photocatalytic activity. The photocatalytic property has been improved, superhydrophilicity has been kept but no antistatic property was observed. Multiwall carbon nanotubes (MWCNTs) have been tested with TiO2 to increase the electrical conductivity. This doping is efficient because MWCNTs increase the conductivity, the photocatalytic activity and maintain the superhydrophilicity. In addition, anticorrosive property has been observed on stainless steel in a preliminary study with the MWCNTs incorporation. The second study is focused on the heterogeneous cyclocarbonation catalyst synthesis to produce, in fine, polyurethane. The catalyst was immobilized on different matrices that are inert from catalytic point of view but that have a potential activator effect. First, with the preselected catalyst, different supports have been investigated. The comparison between the supports has highlighted the activator effect and the texture influence (accessibility of the active sites) on cyclocarbonation yields. Then, with the optimal matrix, different catalysts from a same family have been grafted to choose the best catalyst. Therefore, it has been possible to define the best catalyst and the best support. With this combination, a kinetic study has been performed to determine the best experimental conditions to produce cyclocarbonates. [less ▲]

La communication questionne les manières de considérer la relation entre les familles et les professionnel-le-s de la petite enfance du point de vue de ces dernièr-e-s. Reconnaitre la qualité de service comme un processus contextualisé et objet de négociations entre une série d’acteurs (Dahlberg, Moss, Pence, 2007) au sein d’un « système compétent » (Urban, Vandenbroeck, Peeters, Lazzari, Van Laere, 2011) conduit à souligner l’importance des compétences de négociation dans le chef des professionnel-le-s de l’enfance dans leurs relations avec autrui, en particulier avec les familles dans un contexte de diversité (Pirard, F., Camus, C., Barbier, J. M., forthcoming). Même si les prescrits et les recommandations internationales valorisent un investissement dans le travail avec les familles au sein des institutions d’accueil des jeunes enfants, caractérisé par une double orientation potentiellement en tension visant à la fois un soutien à la parentalité et des démarches coéducatives, force est de constater que sur le terrain, ce travail avec les familles pose souvent question aux professionnel-le-s et peut faire l’objet de significations différentes (Camus, Dehier, Pirard, 2012). Il s’agit de mieux comprendre les difficultés rencontrées par les professionnel-le-s dans leur relation aux familles considérée comme génératrice de risques et de potentialités. La communication offre le regard croisé d'une chercheuse francophone intéressée par les dynamiques co-éducatives mises en place dans les régions centre nord de l'Italie et d’une chercheuse italienne qui a étudié cet objet d’abord dans cette région où la collaboration avec les familles dans la gestion des institutions s’est renforcée depuis de nombreuses années avec des visées communautaires (Sharmahd, 2007), ensuite sur un autre contexte, celui de la Fédération Wallonie Bruxelles où au contraire le travail avec les familles est envisagé de manière essentiellement individualisée et reste encore trop peu développé (Sharmahd, 2009 ; 2016). A partir d’une recherche collaborative comprenant trois entretiens semi structurés avec huit professionnelles de cinq services différents implantés dans une même région (au total 24 auprès), complétés de cinq entretiens semi-structurés avec leur direction, l’analyse des résultats réalisée à partir de codes-catégories spécifiques mettent en évidence deux tensions majeures dans les discours. Les professionnelles mettent en avant une volonté d’ouverture et de souplesse dans leur relation aux familles, mais en même temps elles recherchent une sécurité et dans cette optique, évitent ce qu’elles pourraient considérer comme des prises de risque (être sûr VS ouverture à l’incertitude). Ensuite, elles souffrent d’un manque de reconnaissance, y compris des parents, ce qui peut les conduire à se démarquer de ces derniers par une affirmation de leurs savoirs ou par des pratiques validées par leur institution au travers du projet d’établissement, sans mesurer les effets non désirés d’un tel positionnement professionnel. Ces manières de rechercher une reconnaissance sont en même temps des signes de protection qui peuvent restreindre les possibilités d’autonomie dans l’agir valorisées par ailleurs (être protégé VS être reconnu). Les résultats de cette recherche ouvrent des perspectives pour la recherche et l’action : importance des recherches collaboratives qui impliquent les professionnel-le-s de l’enfance dans l’analyse des résultats, nécessité de cadres d’analyse permettant une approche dialectique de l’objet et une prise en compte des tensions et contradictions dans lesquelles les professionnel-le-s sont pris-es, pistes d’action pour la formation initiale, le développement et l’accompagnement professionnel ainsi que les conditions de travail inscrits dans une approche systémique de la professionnalisation et permettant aux professionnel-le-s de faire face à la gestion des risques et de l’incertitude inhérente à leur activité.

L’« Homme » ou la « structure », la « philosophie du sujet » ou la « philosophie du concept » : ces oppositions balisées dans le cadre de la « querelle de l’humanisme » ont la dent dure. Elles contribuent à surdéterminer la manière dont nous héritons, aujourd’hui encore, de la vie intellectuelle des années soixante. Ce livre se situe délibérément après cette querelle : à rebours des polémiques convenues et des dialogues de sourds, il propose une reconstruction dialogique du problème de la pratique et de son primat supposé sur la théorie, comme enjeu commun à trois auteurs réputés incompatibles : Althusser, Foucault et Sartre. Privilégiant le caractère intempestif des thèses à la systématicité des œuvres, l’ouvrage suit le fil conducteur des rapports entre pratique et structure, prenant la forme d’une « théorie des ensembles pratiques ». Le dialogue ainsi reconstruit accorde une importance toute particulière à la critique par Althusser des philosophies de la praxis constituante – parmi lesquelles la Critique de la raison dialectique de Sartre occupe une place majeure – au profit d’une analyse structurale des pratiques constituées. Ce geste althussérien a un coût, qui consiste à écarter l’ancrage historique et empirique des pratiques au profit d’une théorie de l’histoire comme « procès sans sujet ». Foucault et Sartre se démarquent nettement du traitement althussérien de l’intelligibilité des pratiques. Il s’agit pour eux de sonder l’intelligibilité des pratiques à même le concret : celui des archives de pratiques passées chez Foucault, celui de la dialectique comme logique de l’action en cours chez Sartre. Contre l’idée galvaudée d’un Sartre vieillissant parmi ses contemporains, s’ouvre alors la possibilité d’un véritable dialogue entre Foucault, Sartre, et les sciences sociales sur la question d’une histoire politique de la vérité, qui contribue à remanier en profondeur les rapports entre théorie et pratique.
