Le dispositif du remembrement-relotissement, aussi appelé « Association Foncière Urbaine » en France, est un outil foncier qui permet de réaménager le maillage parcellaire et les espaces publics. Il a pour finalité de matérialiser un projet urbain et il est associé au transfert à une structure de copropriété des droits de propriété relatifs aux terrains nécessaires à la réalisation du projet en question. Il revient ensuite à cette structure de copropriété de gérer le développement du périmètre. À l’issue de l’aménagement, les propriétaires sont rétribués proportionnellement à la valeur de leurs apports fonciers respectifs. Le remembrement-relotissement est considérée comme une « Belle endormie » de l’aménagement . En effet, alors que ce dispositif présente de nombreux avantages (mobilisation du foncier à faible coût, développement de projets intégrés…), il n’est que très rarement appliqué sur le terrain . C’est dans ce cadre que se situe notre proposition, dont l’objectif est de chercher à comprendre les raisons qui limitent l’usage de cette procédure ainsi que les leviers susceptibles d’enfin banaliser sa pratique. Notre intervention sera structurée en trois parties. En première partie, nous développerons les résultats d’une analyse ayant cherché à comprendre la non-utilisation du dispositif au sein du contexte wallon . Ce travail a mis en avant que le remembrement-relotissement souffre d’une mauvaise image auprès des experts wallons de l’aménagement du territoire. Le problème fondamental réside dans la faible faisabilité liée à l’incapacité de mobiliser de concert un nombre suffisamment élevé de propriétaires. La seconde partie de notre intervention sera consacrée à la situation néerlandaise. Aux Pays-Bas, le remembrement-relotissement n’est pas non plus un outil fréquemment utilisé, ce qui s’explique par la tradition de production foncière publique. En effet, il est inutile de chercher à travailler avec les propriétaires lorsque les collectivités locales sont directement à la manœuvre pour mettre en place les projets de développement. Pour autant, en raison de la crise du modèle néerlandais de la production foncière publique, le remembrement-relotissement est aujourd’hui considéré par les autorités néerlandaises comme un outil très important afin de continuer à contrôler les montages opérationnels tout en limitant l’implication financière des collectivités. Il ressort de la comparaison entre les Pays-Bas et le Wallonie que le différentiel de confiance entre acteurs est une explication fondamentale de l’opposition entre les deux contextes. Dans ce cadre, la troisième partie de notre intervention rendra compte d’une recherche en cours qui vise à objectiver l’impact des cultures d’aménagement sur les montages opérationnels. Ce projet, qui s’appuie sur le champ de l’économie comportementale , vise en particulier à traiter des thématiques de l’aversion face aux risques et de l’importance de la confiance dans le développement des partenariats et des coopérations.

FeRh and its first-order phase transition can open new routes for magnetic hybrid materials and devices under the assumption that it can be exploited in ultra-thin-film structures. Motivated by experimental measurements showing an unexpected increase in the phase transition temperature with decreasing thickness of FeRh on top of MgO, we develop a computational model to investigate strain effects of FeRh in such magnetic structures. Our theoretical results show that the presence of theMgO interface results in a strain that changes the magnetic configuration which drives the anomalous behavior. [less ▲]

Twenty-four sand samples were collected from different sand quarries from Douala Littoral Region (Wouri, Dibamba, Mungo and Docteur Anse rivers and Atlantic Sea) along the Guinea Golf. These samples were investigated using gamma-ray spectrometry system. Highest values of 226Ra, 232Th and 40K measured specific activities expressed in Bq Kg−1 units were, respectively, 146.7 (in Youpoue–Bamenda 2) 102.9 (in Village 1) and 928 (in Northern Akwa 6) while the lowest values were found to be, respectively, 11.8 (in Northern Akwa 6), 8.0 (in Bonaberi–Bonamikano 4) and 54.0 (Youpoue 3). The potential radiological hazards parameters were assessed by calculating successively radium equivalent activity (Raeq), outdoor absorbed gamma dose rate (Dout), annual effective dose rate, internal hazard (Hin) and external hazard (Hex) indices and alpha and gamma index from using those sand in the construction of dwellings and large buildings. Results obtained show that annual dose absorbed by inhabitants due to sand construction use in Douala is below 1.0 mSv year−1. Therefore, most of the types of sands studied and incorporated in constructions appear to be safe as building material. The outputs from this research will be useful to assess the radiation hazards of sand building material in humans and to initiate a sand database together with a radiological map of the area at stake.

The criterion of 3% of stuttered disfluencies – (part-)word repetitions, sound prolongations and blocks – is often suggested to diagnose the stuttering in children (e.g., Boey et al., 2007; Yairi & Ambrose, 2005). There is a long-lasting debate among scholars about the relevance of considering monosyllabic word repetitions as stuttered disfluencies, given their high frequency in typically developing children (e.g., Howell, 2013; Wingate, 2001). Yet, these are the prime characteristics that prompt identification of early stuttering by parents (Yairi & Ambrose, 2013). Nevertheless, very few normative data exist concerning the disfluencies occurring in the speech of normally fluent children (Tumanova et al., 2014), and none exist in French. The aim of this study is to examine the need for reference data in French in order to distinguish typical developmental disfluency from stuttering. We used the CHAT transcription system and the coding conventions of FluencyBank to transcribe and analyse the speech disfluencies of twenty monolingual, French speaking children who do not stutter, aged 4 years. FluencyBank (Bernstein-Ratner & MacWhinney) is a shared database for the study of the development of fluency in both normal and disordered populations. It is a project of Talkbank that seeks to archive and facilitate sharing of data relevant to fluency research. [less ▲]

Tillage is a common agricultural practice affecting soil structure and biogeochemistry. Pore network geometries are crucial to oxygen concentration, gas diffusivity, water location and water movement. Soil aggregates, 4–6 mm in diameter and collected from silty loam in Belgium and sandy loam in China, were scanned using a micro-computed tomography scanner. Images with a pixel size of 6.9 μm were then processed with ImageJ software for pore network analysis. The treatments were no tillage (C-NT) and conventional tillage (C-CT) in China, and shallow tillage (G-ST) and conventional tillage (G-CT) in Belgium. The results showed that aggregates in conservational tillage (G-ST and C-NT) had numerous connected pores compared with conventional tillage (G-CT and C-CT). The Euler number (Ev) was significantly lower and visible total porosity and surface area (SA) were significantly higher in conservational tillage (G-ST and C-NT) than in conventional tillage (G-CT and C-CT) in both studied locations. The predominant size of pores was significantly higher in conservational tillage (G-ST and C-NT) than in conventional tillage (G-CT and C-CT) (> 150 μm vs 90–120 μm). Pore location within the aggregates also showed differences, with porosity being evenly distributed in the aggregates under conventional tillage (G-CT and C-CT). Under conservational tillage (G-ST and C-NT), the aggregates were heterogeneous, showing higher porosity at the center of the aggregates. There was a higher soil organic carbon (SOC) content in the external layer than in the internal layer in conservational tillage in Belgium (G-ST). In no tillage in China (C-NT), the SOC in the external and internal layers, however, showed similar results. Overall, conventional tillage (G-CT and C-CT) reduced the proportion of the largest pores within soil aggregates, whereas there was no significant relationship between pore morphologies and SOC content. Further investigation is required to measure the active and slow carbon pool distribution in the different layers and under different tillage practices. [less ▲]

Ce texte vise tout d’abord à illustrer l’hypothèse selon laquelle le langage verbal n’est pas le traducteur unique et universel de toutes les sémiotiques (visuelles, musicales, audiovisuelles, etc.) comme l’affirment la sémiologie de Roland Barthes et l’approche linguistique. Nous comparons ensuite la notion de réflexivité à celle de métalangage : si les études sur la réflexivité sont assez répandues dans plusieurs disciplines concernant l’image dont en histoire de l’art, il n’en est pas de même pour la notion de métalangage qui implique généralement la hiérarchie d’un langage sur l’autre. Nous prenons en considération à ce propos les critiques des détracteurs de la possibilité d’envisager un métalangage visuel qui s’appuient sur la conviction que le langage visuel n’a pas d’alphabet ni de grammaire stables, voire qu’il est démuni d’unités morphologiques ainsi que de règles syntaxiques. Nous illustrons brièvement des tentatives de construire un alphabet d’unités visuelles, telle que celle de Paul Klee, et nous passons en revue des concepts opérationnels qui permettent de concevoir en image une dimension méta et notamment celui de « semi-symbolisme » selon A.J. Greimas et J.-M. Floch ainsi que celui de « pli » chez Ch. Metz. [less ▲]

L’ambition de cet ouvrage est de développer en sémiotique visuelle une théorie et une méthodologie originairement formulées en linguistique, celles de l’énonciation. L’analyse énonciative permet de décrire les points de vue à partir desquels l’image a été conçue et d’étudier les valeurs, les formes de vie ainsi que les idéologies offertes à l’observateur. Les plis du visuel revient sur la théorie inaugurale d’Émile Benveniste, sur ses apports et ceux de l’histoire de l’art (Louis Marin, Meyer Schapiro, Victor Stoichita…) et de la sémiotique contemporaine en vue de restituer la trajectoire théorique de la sémiotique visuelle et de dépasser la simple transposition dans l’image d’un appareil formel de l’énonciation validé en linguistique. Cet ouvrage se donne plus exactement pour objectif principal de constituer un organon de concepts inter-définis et d’instruments analytiques permettant de diversifier les différents types d’énonciation dans le cadre du langage visuel, à partir non seulement des constructions langagières de chaque image (type de perspective, rapports entre figure et fond, entre espaces englobant et englobé, entre forme et texture, etc.) mais aussi de leur appartenance à différents domaines socio-culturels (la publicité, l’éducation, la politique, etc.) et à différents médias (le cinéma, l’art numérique, les jeux-vidéo, etc.). Il s’articule en trois parties, « Enonciation et pratiques de l’audiovisuel », « Enonciation et perception. Cas de la peinture, de la photographie et du numérique », et « Enonciation et métalangage visuel », qui explorent trois points fondamentaux de la réflexion sémiotique contemporaine : la question de la transposabilité/transversalité de l’appareil formel de l’énonciation et de la spécificité de chaque pratique médiatique, la relation entre énonciation et perception et les propriétés métalinguistiques de l’énonciation. Au fil des différentes contributions, cet ouvrage propose ainsi un parcours de la sémiotique visuelle qui accompagne l’innovation technologique et médiatique à l’origine des nouvelles formes d’image ; il met l’accent sur la spécificité de l’énonciation dans les langages visuel et audiovisuel et impose une conceptualisation spécifique des contextes médiatiques.

Fire tests remain a precious tool to comprehend the behavior of structures under accidental fire conditions. The common practice in fire testing is to isolate the tested element in a furnace in which the mechanical support conditions are maintained constant throughout the test. However, such tests fail to capture the effect of the structure surrounding the element of interest when this effect cannot be realistically modeled by a free or fixed support condition. It has been observed in large-scale tests that the behavior of entire structures under fire is different compared with the behavior observed in traditional tests on isolated elements. This indicates the importance of capturing accurately the boundary conditions between the element and the remainder of the structure when characterizing the behavior of this element in fire. The literature describes a few attempts at performing fire tests under realistic boundary conditions. In the latter, the tests were still performed on isolated elements but the boundary conditions were updated during the test taking into account the characteristics of the remainder structure. This technique, called hybrid testing, represents an appealing solution to test structural elements under realistic boundary conditions. Hybrid testing is a methodology which offers the advantage of testing singular structural elements (or a group of structural elements) named physical substructure PS while at the same time considering the characteristics of the remainder substructure named numerical NS, thus allowing to model realistic boundary conditions. Pioneering work has been done in the seismic field where this technique is now well described, but the implementation of this methodology for structural fire testing raises important challenges due to the specificities of the field. A few hybrid fire tests have been performed in the past on columns and slabs. Their analysis shows that they all use a similar methodology, which is referred to as the first generation method in this work. The objective of the thesis was to develop and implement a hybrid fire testing methodology on a reinforced concrete beam extracted from a moment resisting frame. Initially, it was intended to build on the first generation method, but after its detailed analysis in the development stage it has been observed that the process can be unstable. The value of the stiffness ratio between the numerical substructure and the physical substructures has been identified as critical in governing the stability of the test, dictating whether the hybrid test needs to be applied in displacement control or force control. This is a severe drawback of the first generation method, as the stiffness ratio is unknown and changing during the test; besides different degrees-of-freedom can require different procedures during the test. Therefore, it has been shown that the first generation method should not be applied as it can lead to instability prematurely during the tests. To overcome the drawbacks of the first generation method, the objective was to develop a new technique that leads to interface equilibrium and compatibility while at the same time is unconditionally stable (i.e. independently of the stiffness ratio). Thus a novel methodology was developed and applied to the case of a concrete beam (PS) being part of a concrete moment resisting frame (NS). The novel method makes use of the PS’s stiffness in addition to the NS’s stiffness as it was the case in the first generation method. The stiffness matrix of the PS is unknown during the test therefore the initial tangent stiffness matrix is considered during the calculations. The latter choice influences the value of the time step to be adopted during the test. Every time step the boundary conditions are updated and it will be discussed how the chosen value can influence the results. A predetermined matrix is used to describe the behavior of the NS during the hybrid fire tests. This approach does not capture the nonlinearity of the remainder but at the same time the implementation is relative simple and the negative effect of the time calculation is eliminated. The procedure to compute the predetermined matrix of the NS is presented in this thesis. One possible direction in the future development of hybrid fire testing is to model the NS in the finite element model. The algorithm of the proposed method is developed and implemented in nonlinear finite element software SAFIR in order to perform virtual hybrid fire tests. The same algorithm is translated in order to be implemented by the company in charge of the control system at the CERIB furnace facility. The thesis also presents a traditional fire test that has been performed on the beam, in order to highlight the differences when testing structural element without and with the real boundary conditions. For the hybrid test, three degrees-of-freedom are controlled at the interface. The furnace facility has an important role to perform successful test where the equilibrium and compatibility are ensured and no instability occurs during the test. The impediments encountered during the tests will be discussed along with the recommendation for a successful hybrid fire test. [less ▲]

Studies that focused on family issues have allowed a great understanding of the aspectsrelated to its subsystems, such as parenting desire and its expectations, couples’satisfaction and quality of child’s outcomes. All these aspects are greatly interconnectedand contribute to the creation of specific family dynamics, such as the quality offamily interactions. The present study focuses on intuitive co-parental behaviors andthe quality of couple relationship observed during the decision process (intention anddesire) to be (or become) parents. Our first goal was to explore these aspects ina cross-national sample made of Italian and Belgian heterosexual, lesbian and gaycouples. We then aimed to evaluate if the degree of internalized homophobia affectsco-parental alliance. The quality of couple relationship and co-parental behaviors havebeen evaluated through the recruitment of a group of 115 stable heterosexual, gay andlesbian couples (230 individuals, 20–50 years of age) without children, who wanted tobecome parents. We used the Prenatal Lausanne Trilogue Play to evaluate the Co-parental Alliance; the couple’s satisfaction was assessed with the Dyadic AdjustmentScale and the Internalized Homophobia with the MISS-LG. In line with the existentliterature, the analysis did not find any difference between lesbian, gay and heterosexualcouples in terms of co-parental alliance. High levels of couple adjustment lead to betterparental performances among both Italian and Belgian couples. The results suggestalso that sexual stigma differs from one country to another, and it has an impact on thecapability of managing co-parenting. Clinical implications should be verified in furtherlongitudinal studies in order to observe the impact on the inter-generational transmissionof psychopathology. [less ▲]

Modern biotechnology is a driving force and a full grown industry in the international economy with ongoing and rapid innovations. The emphasis of this dissertation is on the valorization of red biotech, i.e. pharmaceutical and healthcare applications. Belgium has firmly established itself as an international red biotechnology country, with a world class biotechnology industry in the Flanders and Wallonia bioRegions. Developing a domestic biotechnology industry - and hence new biotechnology firms - can be influenced by regional policy. The pharmaceutical-biotechnology regional and sectoral innovation system is characterized as an international and dynamic network architecture involving numerous players engaged in drug discovery. Regional governments and dedicated public and private network organizations have supported emerging new biotechnology firms by providing critical resources and by promoting an institutional environment that has enabled partnerships between universities, highly specialized research centers, small science based academic spin-offs and corporate spin-outs and large global pharmaceutical companies. Both policy and big firms look at the new biotechnology firms from a strategic point of view. The policy objective is the emergence of new and sustainable firms in the region; the big firms objective is the filling or renewal of the pipelines of products. New biotechnology firms are both beneficiaries and targets of strategic partnering alliances with large and global (bio)pharmaceutical companies. A number of the Belgian new biotechnology firms hold a nodal position as “ most preferred partner ” with multiple alliances in dynamic R&D networks. They have a high degree of integration into global technological networks through strategic alliances. Strategic alliances and open innovation are commonly leveraged. Despite their small size and relative immaturity, some of the new biotechnology firms are able to adopt innovative business models by providing R&D and services to large biopharmaceutical companies and by cooperating with them through open innovation.

Regulation in terms of greenhouse gas emissions becomes more and more stringent and the fuel consumption targets decrease. In order to meet these demands, vehicle electrification has increased over the last decade. With the arrival of plug-in hybrids and battery electric vehicles, efficient battery cooling system becomes a necessity and has to be integrated into the vehicle thermal management. One of the possibility is to integrate a chiller in the air conditioning system for extreme operating points. Moreover, this kind of system can be dedicated to luxury or large passenger cars for which a secondary evaporator is present to guarantee the comfort for rear passengers. The main challenge of this air-conditioning architecture is to maintain simultaneously the cabin thermal comfort via one or two evaporators on one hand and to maintain the battery cells in an ideal temperature range on the other hand.
