Au lendemain de la bataille de Sedan (1er septembre 1870), la Belgique accueillit un grand nombre de blessés français et prussiens. Le transfert des grands blessés se fit grâce à l'action de l'association belge de secours aux militaires blessés en temps de guerre (Croix Rouge de Belgique). L'accueil favorable des autorités belges répondait autant à des considérations humanitaires que politiques. Sur le plan technique, les graves blessures causées par les armes à feu, de plus en plus puissantes, posèrent de nouveaux défis aux chirurgiens belges. [less ▲]

For some years now, spectroscopic measurements of massive stars in the amateur domain have been fulfilling professional requirements. Various groups in the northern and southern hemispheres have been established, running successful professional-amateur (ProAm) collaborative campaigns, e.g., on WR, O and B type stars. Today high quality data (echelle and long-slit) are regularly delivered and corresponding results published. Night-to-night long-term observations over months to years open a new opportunity for massive-star research. We introduce recent and ongoing sample campaigns (e.g. ɛ Aur, WR 134, ζ Pup), show respective results and highlight the vast amount of data collected in various data bases. Ultimately it is in the time-dependent domain where amateurs can shine most. [less ▲]

Outil d’évaluation interactive, les boitiers de vote, apparaissent comme un outil propice à la mise en œuvre d’une pédagogie favorisant l’engagement de tous les étudiants dans le cours et en permettant une régulation du processus enseignement/apprentissage « on line ». La littérature déjà abondante apporte des éléments qui vont dans ce sens bien que certains résultats viennent également questionner les bénéfices cognitifs des BVE. Parallèlement aux comptes-rendus d’expérience, les recherches, essentiellement quantitatives, s’intéressent davantage aux appréciations des acteurs et aux performances des étudiants qu’à l’observation des usages en situation. Afin d’appréhender l’utilisation effective des BVE dans les cours, des études de cas approfondies ont été conduites à l’université Blaise Pascal selon un protocole de recueil de données reposant sur des entretiens conduits avec les enseignants avant et après des séances de cours observées et filmées ainsi qu’un recueil des points de vue des étudiants. A partir des résultats obtenus, nous avons construit un schéma théorique visant à modéliser les dimensions structurantes de l’apprentissage actif avec les boitiers qui sera présenté lors de la communication.

This paper presents an explicit multi-model predictive controller (MMPC) for a waste heat recovery system (WHRS) mounted on a heavy duty truck engine. WHRS based on the Rankine cycle principle attracts a lot of interest in the heavy duty industry, over the past few years, to decrease the fuel consumption and reach the future pollutant emissions standards. Control issues have still to be faced before the integration of such a system into a vehicle. Model predictive controllers suits really well for our control purpose due to their ability to handle online optimal control problem. This paper focuses on the development of an explicit control law based on MMPC with aim to control the fluid temperature at the inlet of the expansion machine in order to increase the system performance and the reliability.

The objective of this paper is to study the effect of structural dissipation on the dynamic response of tape springs using experimentally-validated finite element models. In order to reach this goal, an experimental set-up is built. It consists of two tape springs connected to a fixation support and a dummy panel. The data are collected through a force plate and a 3D motion analysis system. The post-treatment of the experimental results and a comparison with a finite element model show that the Kelvin-Voigt model gives a fair approximation of the structural damping for small oscillations, however, more advanced model should be considered in future works for a better understanding in case of large displacements.

The work reported in this paper is part of a wider research program intended to provide the repair industry with improved fundamental knowledge to implement rational design methods and rules for repairs. In that regard, there is a strong need to study the fundamental relationships and parameters that underlie the repair compatibility concepts, in particular those relating to dimensional compatibility. In the first part of the paper, classical formulas derived for thick cylindrical specimens were used to analyze the tensile stress buildup in annular restrained shrinkage test specimens, taking into account the restraining conditions the investigated ring test method and the individual concrete properties/phenomena determined experimentally (elastic modulus, creep coefficient, drying shrinkage deformation). By comparing the ring test results with the calculated tensile stresses, the validity and accuracy of the theoretical approach could be appraised. A quantitative approach for the evaluation of the performance of concrete repair in terms of dimensional compatibility was then developed. Derived from the basic strain balance approach (ratio between the total deformability in tension and the drying shrinkage deformation), a parameter referred to as dimensional compatibility index (CI) was introduced in order to analyze the evolution of dimensional compatibility as a function of time for a given concrete mixture, taking into account the actual degree of restraint in the element. Compatibility index evolution curves were calculated for various repair concrete mixtures in order to highlight material behavior relating to composition parameters and temperature. As it requires the evaluation of a limited number of individual properties that are for most readily available (i.e. strength, elastic modulus, shrinkage), the compatibility index expressed in terms of deformation carries a lot of potential as a relatively simple and convenient analytical tool for assessing the cracking sensitivity of concrete repair materials. Overall, it can be stated that a good correlation was found between the ring test results and the tensile stress values calculated based on individual concrete properties / phenomena and that the proposed calculation method lays ground for evaluating quantitatively the dimensional compatibility of repair materials and defining suitable performance criteria.

The notion of citizenship rests on the cleavage between national and international law as a matter predominantly shaped by state's internal acts, in accordance with limits determined by the state's interrelations with other states and rules of international law. The respective dichotomy generates further branching of the notional structure, making it multilayered, multidimensional and fluid. The simplified definition of citizenship conceptualises it as a real and effective link between the state and an individual, however, in social reality the notion transcends the respective formal perception and interferes with conceptions of identity, belonging and sentiments. With the aim of positioning citizenship within the domain of contemporary international human rights protection, this paper focuses on the analysis of jurisprudence of the European Court of Human Rights which has in several of its recent judgments provided for an original interpretation of the right to citizenship, subsuming it under the ambit of Article 8 of the Convention for the Protection of Human Rights and Fundamental Freedoms on the right to private and family life. Although Conventional norms do not grant the right to citizenship expressis verbis, an insight into three judgments (Genovese v. Malta, Mennesson v. France and Jeunesse v. the Netherlands) demonstrates that the Court's innovative interpretation of Article 8 has proved that flexible notions of private and family life are comparable enough with citizenship to embrace the aspects of a person's social identity which make up the essence of the concept of citizenship.

In recent years the increasing interest for eco-sustainable building materials and the rising issue of plastic waste disposal are leading to the engineering of new composite construction materials incorporating post consumer recycled plastics, able at the same time to meet new standard requirements, in terms of energy efficiency, and to reduce the consumption of natural resources. In the context of these issues, we have performed investigations on the effects of the addition of foamed artificial aggregates deriving from recycled plastic materials to a cementitious mortar. For this purpose, several mortar samples containing natural sand and different amounts (10, 25 and 50 % by volume) of foamed recycled plastic wastes were produced. The foaming of the recycled plastic waste was performed in laboratory by a foam extrusion process using a blowing agent (2 wt.%). An artificial aggregates particle size distribution similar to standard sand was used. Rheological and physical properties of lightweight mortar were studied. The improved surface roughness of foamed plastic aggregates ensures a more continuous interface and the presence of surface pores provides interlocking effect with cement paste. Replacement of natural sand by artificial aggregates produces a lightweight mortar but reduces mechanical properties. [less ▲]

Technology assessment (TA) and TA-like activities in countries like Japan have a unique history and continue to play a role in contemporary science, technology, and innovation (STI) processes. The aim of the discussion of TA’s experience in East Asia is how STI governance is locally enacted in Asian knowledge-driven economies, as TA activities develop in conjunction with STI policies and programs. To render these processes, policies, and programs visible and to understand their implications for STI governance, a panel at the Berlin conference on TA discussed contributions that described and conceptualized, for example, how TA activities have emerged in Asian knowledge-based economies (KBE), in which particular forms (e.g., academic and parliamentary TA programs), to which technologies and/or actors they are linked, and which methods are used and why. The panel also sought to compare and contrast how TA is (or is not) institutionalized in Asian countries and regions, and to point to prospects for expansion of TA capacity. In doing so, the panellists placed the development of TA in a historical, sociological, and comparative perspective, and opened space for critical reflection on the potential, problems, and limitations associated with initiating TA in Asia and with KBEs overall.

This paper present an experimental study carried out on a swatch-plate piston expander. The expander was integrated into an ORC test-bench using R245fa. The performances are evaluated in term of isentropic efficiency and filling factor. The maximum efficiency and power reached are respectively 53% and 2 kW. Inside cylinder pressure measurements allow to compute mechanical efficiency and drown P-V diagram. A semi-empirical simulation model is then proposed, calibrated and used to analyse the different sources of losses. [less ▲]

Over the past decades, researchers studying adult metacognition have placed a heavy emphasis on how expectations and naïve theories about memory functioning can improve memory accuracy through the implementation of some metacognitive rules. By contrasts, however, research on metacognition in children has only recently started to pay attention to the influence of these heuristic-based judgments on decision making. Generally, the results of these studies indicate that memory decisions are already based on some heuristics by the ages of 7-8 years. Thus far, the question of whether younger children can do the same has widely gone unexamined. The present experiment investigates whether young children are able to reduce their false recognitions rate after distinctive encoding through the implementation of a strategic metacognitive rule. Specifically, we examine the use of a retrieval strategy called the distinctiveness heuristic whereby people infer that an event has not occurred when they cannot remember expected memorial information about it. Seventy-two children, aged 4, 6, and 9 years, studied two lists of unrelated items. One of these lists was visually displayed (picture/dictinctive condition) while the other was presented auditorily (word/no-distinctive condition). After each study phase, participants completed recognition tests. Finally, they answered questions about their explicit knowledge of the distinctive-encoding effect. The results revealed that even the youngest children in our sample showed a smaller proportion of intrusions in the picture condition than in the word condition. Furthermore, the findings of the signal detection analyses are consistent with the hypothesis that the lower rate of false recognitions after picture encoding results from the implementation of a conservative response criterion based on the participants’ metacognitive expectations (distinctiveness heuristic). Moreover, the absence of correlation between children’s explicit knowledge of the distinctiveness rule and their effective use of this metacognitive heuristic seems to indicate that its involvement in memory decisions could be mediated by implicit mechanisms.

This study investigates tracking a table-tennis ball rapidly from video captured using low-cost equipment for umpiring purposes. A number of highly efficient algorithms have been developed for this purpose. The proposed system was tested using sequences capture from real match scenes. The preliminary results of experiments show that accurate and rapid tracking can be achieved even under challenging conditions, including occlusion and colour merging. This work can contribute to the development of an automatic umpiring system and also has the potential to provide amateur users with open access to a detection tool for fast-moving, small, round objects.

Matériels et méthodes : l’étude porte sur un crâne déformé provenant d’Ancón au Pérou, inventorié au Muséum National d’Histoire Naturelle (MNHN) de Paris en 1889. L’étude est géographique, historique, macroscopique et tomodensitométrique. Résultats : situé sur la côte à 40 km au nord de Lima, la capitale du Pérou, le site d’Ancón est un site archéologique de la période lithique, et un lieu de sépulture depuis l’époque Chavín (1250 à 250 av. J.-Chr.). Dès l’époque Chavín, les peuples du Pérou ancien construisaient des centres cérémoniels dirigés par une élite théocratique, et déformaient le crâne des enfants dès les premiers jours de la vie, à l’aide de moyens de pression variés. La déformation du crâne d’Ancón est une déformation antéro-postérieure oblique, brachycéphale, bilobée et asymétrique, sans trépanation ni déformation dentaire associée. C’est une variante bilobée du type Huaura de déformation crânienne, qui est associé aux régions de Chancay-Ancón et Lima. L’étude tomodensitométrique des variations d’épaisseur de la voûte, avec amincissement en regard des zones de pression, a montré que la déformation était intentionnelle, et caractérisée par une pression fronto-pariéto-temporale bilatérale surtout antérieure et dégressive d’avant en arrière, associée à une pression frontale, occipitale, et sagittale médiane. En l’absence de contexte et de datation, l’ancienneté du crâne étudié ne peut pas être précisée au long d’une période de presque trois millénaires, jusqu’à la domination Inca et l’arrivée des Espagnols (1532). Le crâne pourrait appartenir à l’une ou l’autre des cultures successives du site d’Ancón : Chavín, Baňos de Boza o Miramar, Lima, Wari, et Chancay (1200 à 1470), dont les céramiques représentent la déformation bilobée. Le crâne est probablement celui d’une femme âgée de plus de 45 ans à son décès, de statut social élevé, faisant partie de l’élite magico-religieuse, politique et économique dirigeante. L’étude de l’endocrâne a permis d’observer la déformation des veines superficielles et des lobes du cerveau. Il existe des signes de parodonpathie chronique à un stade avancé. Un abcès d’origine dentaire pourrait avoir été la cause du décès. Conclusions et perspectives : en ce qui concerne la pratique des déformations crâniennes, la région d’Ancón-Chancay et de Lima paraît être remarquable à trois égards : par le grand nombre de crânes déformés, par le grand nombre de crânes bilobés, et par la proportion importante de femmes, dont on peut supposer qu’elles étaient nées de familles nobles, et destinées dès l’enfance à faire partie de l’élite théocratique. La reconstitution 3D de l’épaisseur de la voûte crânienne a permis pour la première fois à notre connaissance de caractériser ce type de déformation, et pourrait permettre de reconstituer l’appareil déformateur. Seule la reprise des exhumations programmées sur le site d’Ancón, dans le cadre d’un projet prospectif pluridisciplinaire, pourrait permettre de mieux préciser la proportion d’individus à crâne déformé, la proportion des crânes bilobés, et le sex ratio, dans chaque contexte historique et socio-culturel de ce type de déformation crânienne intentionnelle ; et, peut-être, de retrouver in situ l’appareil déformateur correspondant.

Driven by future emissions legislations and increase in fuel prices engine, gas heat recovering has recently attracted a lot of interest. In the past few years, a high number of studies have shown the interest of energy recovery Rankine based systems for heavy duty trucks engine compounding. Recent studies have brought a significant potential for such a system in a Heavy Duty (HD) vehicle, which can lead to a decrease in fuel consumption of about 5% [Wang et al. (2011)] and reduce engine emissions. But many challenges still need to be faced before the vehicle integration. This paper presents a control strategy development for waste heat recovery Rankine based systems in heavy duty trucks. Due to the highly transient operating conditions, improving the control strategy of those systems is an important step to their integration into a vehicle. It is shown here that moving to more advanced control strategies than classical PIDs lead to some gains in terms of performance. Due to the limited availability and high operational cost of test bench, the validation of such a controller is done on a representative and previously validated model. [less ▲]

Since migration was mentioned as a pattern of development, the debates have never ended. In Vietnam, the industrial zone has been developed rapidly for more than 20 years. However, the rate of migrant labor is high. Based on push and pull theory of migration the study is to find the reasons that push or pull rural labors to migrate to industrial zones. By surveying 190 migrants in industrial zone, the study found that the employment in the zones is not stable in the long run. Migration not always driven by poor economic condition of the houhsehold in the areas of origin, it is the way of life of young rural labor and the migrants in the zones seem to be pulled rather than pushed.

Fast rotation in massive stars is predicted to induce mixing in their interior, but a population of fast-rotating stars with normal nitrogen abundances at their surface has recently been revealed (Hunter et al. 2009; Brott et al. 2011, but see Maeder et al. 2014). However, as the binary fraction of these stars is unknown, no definitive statements about the ability of single-star evolutionary models including rotation to reproduce these observations can be made. Our work combines for the first time a detailed surface abundance analysis with a radial-velocity monitoring for a sample of bright, fast-rotating Galactic OB stars to put strong constraints on stellar evolutionary and interior models.

How could we link together digital dictionaries which have no common lexical units, but deal with the same linguistic area? And how could we do that automatically, in order to ensure that all future updates of these dictionaries are taken into account in the linking process? This contribution exposes the solutions that we propose in the field of French and Gallo-Romance historical lexicography. The digitalisation currently in progress of a work of scientific reference, i.e. the Französisches Etymologisches Wörterbuch (FEW), gives us a mean to link together other dictionaries, such as the Dictionnaire Etymologique de l’Ancien Français (DEAF), the Dictionnaire du Moyen Français (DMF), the Anglo-Norman Dictionary (AND), or the Atlas Linguistique de la Wallonie (ALW), through the use of the references of these dictionaries to the FEW. Concrete examples of linking lexical data are discussed in this context. We also describe a simple peer-to-peer protocol allowing e-dictionaries to be automatically linked in a distributed way using the references of their articles. An implementation based on a simple REST API is suggested to let teams maintaining different e-dictionaries keep their own technologies and data schema. [less ▲]

La femme vietnamienne a depuis très longtemps assuré un rôle très important dans le développement socio-économique et culturel du Vietnam. Toutefois, en raison d’une forme de paternalisme lié à des aspects sociaux et culturels, les femmes n’ont pas été autorisées à jouer un rôle prépondérant dans les métiers traditionnels des entreprises rurales développées au Vietnam. Aujourd’hui, avec le changement des conditions économiques et sociales, on assiste à une participation accrue des femmes dans les activités autrefois réservées aux hommes comme la production directe, le commerce et même la gestion de l’entreprise. Au travers d’une recherche empirique dans les petites entreprises d’artisanat d’art des communes où se trouvent des villages traditionnels célèbres du Vietnam, on peut observer le changement dans le rôle exercé par les femmes. Cela doit néanmoins encore être accompagné par des politiques convenables capables de réduire l’inégalité du genre dans les activités de métier traditionnel et contribuer ainsi à un développement rural équilibré.

This paper shows how the design of a structure can evolve when considering a stressbased topology optimization along with fatigue failure constraints. More precisely, fatigue failure is added in a stress-based topology optimization Matlab code by following the approach of the design of machine elements, i.e. based on S-N curves or fatigue criteria. The fatigue is introduced through weel-known criteria for high-cycle fatigue such as the Sines and Crossland criteria. The paper presents how these criteria can be formulated for a topology optimization problem. Numerical results for both criteria are successively compared and discussed. The character of fatigue failure in the optimization procedure is illustrated as well as some issues that have to be improved in future work. [less ▲]

In equines, ingestion of hypoglycin A, a toxin produced in the seeds (samaras) of sycamore maple (Acer pseudoplatanus) tree alters the energetic metabolism of muscle cells and results in atypical myopathy (AM). This alterations leads to a characteristic biochemical profile of acylcarnitines (AC) that enables to confirm the diagnosis of AM. This study aims at validating a methodology for the dosage of hypoglycin A in vegetal extracts but also in blood. In addition, the biochemical profile in AC has been determined in AM cases (5 survivors and 13 deceased) and in 5 horses suffering from exercise-induced myopathy. The AC profiles of these horses have been compared to the one of healthy horses (n = 35). This study showed that hypoglycin A was present in seeds and spring seedlings of sycamore and also in blood of AM cases horses. In addition, the establishment of AC profile contributes to the diagnostic and helps to assess the prognosis of AM cases. [less ▲]

The prediction of the shear resistance of connections as presently given in Eurocode 3, Part 1-8, cannot be applied in a straightforward way to the connection for tubular racking structures realized by means of long through bolts. In order to verify the possibility to extend the codified approach to such joint configurations, in the present paper a finite element model with three-dimensional solid elements is established investigating the behaviour of the connections under shear load in a wide range of variability of the geometrical parameters. The validation of the numerical model has been performed starting from the results of experimental tests already performed by the authors at the laboratory on Materials and Structures of the University of Liège. Based on the finite element results, the load displacement curves for all the assemblies were successfully predicted evidencing the important role played by the hole’s geometry and reduced diameter of the bolts on the initial stiffness of the connections. The results of a parametric study by means of a calibrated FE model in Abaqus/CAE allowed to verify the possibility to extend the formulations provided by EC3 for predicting the bearing resistance of plates to these kind of connections and to analyse the influence of the main parameters governing the bearing resistance: the distance e1 between the hole and the edge of the tube, the distance e2 between the hole and the lateral edge of the plate composing the tube section and the thickness t of the tube.

The increasing number of crane accidents recorded over the last years might be understood as a need for progress on crane modeling. The induced risk of self-excited vibrations has already been investigated through numerous experiments. This work presents a simple numerical model of a crane in a turbulent wind field, in order to support the available experimental approaches. First, the problem is defined with the necessary assumptions of the model. Second, the equation of motion is developed and wind characteristics are detailed. This equation presents several specificities requiring dedicated resolution methods. In a first analysis, the crane model is simplified in order to approach the behavior of the parametric pendulum and enable a general comparison of both responses. Indeed, the parametric pendulum is a well-known problem that is already widely described in the literature. In a second step, the response of the crane is studied under a realistic stochastic wind load with the full model. [less ▲]

Since 2000, we can observe important changes in traditional production systems of coastal communes in North Vietnam. Faced with relatively low incomes, rice farms converted the surfaces available to them in aquaculture ponds. These are difficult to reverse conversions were carried out by farmers seeking to improve family income in areas of relatively low rice productivity. These changes have had a significant impact on the revenues generated in coastal villages with changes in work organization and the upstream business opportunities for feed plants. This type of family aquaculture has grown rapidly to meet domestic demand but also to export markets. Faced with these voluntary initiatives, the Vietnamese authorities have had difficulties to coach and support these new producers in sustainable development schemes for fresh water or brackish water aquaculture. In addition, climate change could significantly affect these areas particularly exposed to rising sea waters. Moreover, aquaculture producers respond to logic relatively isolated individual entrepreneurs. They deliver their products to many collectors who engage strong competition. This is particularly true at the sub-sectors supplying the domestic market. The Vietnamese marketing system for aquaculture products is generally considered competitive and efficient. It involves different stakeholders (collectors, dealers, wholesalers and processors) that develop often difficult short-term strategies to understand and which do not permit a good traceability of production. At producer level, understanding of market mechanisms is very limited which makes it difficult to decision support for investments and marketing. Meanwhile, producers are exposed to high price volatility. Small producers oriented towards the local market are particularly exposed and vulnerable to this issue and it is important to understand the strategies that can be implemented to ensure against this form of risk. In this context, this paper describes two initiatives conducted in the Northern area of Vietnam to strengthen the sustainability of clam’s farms and supported by researchers from Vietnam National University of Agriculture.

In the context of Renovation in Vietnam, there is a large wave of peasant migrants moving out of agriculture to find the jobs in nonfarm sectors. The interactions of migration and agricultural production can be seen in different aspects. This research focused on behaviors of farm households. There are the less evidences of labor shortages at both production and hiring labors. Maintenance at reasonable level rather than rather than the abandonment or expansion of agricultural activites is likely the more popular trend. Although remittance presented as a stable financial inflow ensures the sufficient cash which would strenghten the rural households' livelihoods security and reduce force of selling agricultural production for cash, agriculture production is still fundamental livelihood activity for household security.

Recent studies have shown that AlSi10Mg processed by Laser Beam Melting (LBM) exhibits a much finer microstructure when compared to its cast counterpart as a consequence of the much faster cooling rates imposed in the LBM process. Such microstructural refinement causes a significant increase in strength and hardness, to such an extent that as-fabricated LBM AlSi10Mg was reported to present hardness value of 127 ± 3 Hv0.5, similar to the hardness of high pressure die cast AlSi10Mg in the aged condition (i.e. 130-133 Hv). Yet, little attention has been given so far to the influence of thermal treatments on the microstructure and mechanical behavior of LBM AlSi10Mg. The present work hence aims to investigate the effect of two different types of heat treatments – i.e. (i) stress relief and (ii) solutionizing and ageing − on the microstructure, hardness and tensile properties of LBM AlSi10Mg.

Les nombreux défis que représente la transition sociale et écologique vers une société post-croissance constituent des problèmes typiques d’action collective. La littérature récente consacrée à ces derniers met en exergue la notion de système « polycentrique » de gouvernance des biens publics, qui implique une multiplicité de centres de décision indépendants partageant un ensemble de règles communes. Un système polycentrique suppose également un degré élevé de participation citoyenne auto-organisée. Les formes organisationnelles adaptées pour encadrer l’action citoyenne ont cependant été jusqu’à présent peu étudiées, à tout le moins dans leur lien avec la transition. Cet article vise à combler ce vide et à explorer les rôles que peuvent jouer les organisations d’économie sociale à cet égard. Nous montrons comment leurs spécificités organisationnelles les rendent aptes à encadrer l’action citoyenne auto-organisée et donc à favoriser la mise en place de systèmes de gouvernance polycentrique de la transition social-écologique. Enfin, nous appliquons cette grille de lecture à deux domaines d’activité : l’énergie et l’alimentation. [less ▲]

The primary objective of this paper is to explore the influence of socio-demographic and contextual variables on the multimodal character of public transit journeys. Accounting for multimodality in public transit journeys is important from a demand modeling point of view, especially in the assessment of new projected public transit infrastructure. To meet the objective, data from the national household travel survey of Flanders (Belgium) is analyzed. Based on 2,202 public transit journeys, the main public transit mode choice (bus/tram/metro or train) and access/egress mode choice are simultaneously estimated using a multinomial logit model, and by explicitly making a distinction between unimodal and multimodal transit journeys. The results indicate that various socio-demographical (e.g. age, gender, level of education, household income) and contextual factors (e.g. journey distance, journey motive, urbanization degree, car availability) significantly influence the joint decision process. Total journey distance and car availability are identified as the most important explanatory variables. In terms of model performance, the model appears to yield satisfactory predictions, justifying the integration of the model in more general demand modeling frameworks. [less ▲]

Monitoring tropical forest carbon stocks changes has been a rising topic in the recent years as a result of REDD+ mechanisms negotiations. Such monitoring will be mandatory for each country willing to benefit from these financial incentives in the future. Aerial and satellite remote sensing technologies offer cost advantages in implementing large scale forest inventories. Despite the recent progress made in the use of airborne LiDAR for C stocks estimation, no widely operational and cost effective method has yet been delivered for central Africa forest monitoring. Within the Maï Ndombe region of DRC, the EO4REDD project develops a method combining satellite, aerial and ground measurements. This combination is done in three steps: [1] mapping and quantifying forest cover changes using an object-based semi-automatic change detection (deforestation and forest degradation) methodology based on very high resolution satellite imagery (RapidEye), [2] developing an allometric linear model for above ground biomass measurements based on dendrometric parameters (tree crown areas and heights) extracted from airborne stereoscopic image pairs and calibrated using ground measurements of individual trees on a data set of 18 one hectare plots and [3] relating these two products to assess carbon stocks changes at a regional scale. Given the high accuracies obtained in [1] (> 80% for deforestation and 77% for forest degradation) and the suitable, but still to be improved with a larger calibrating sample, model (R2 of 0.7) obtained in [2], EO4REDD products can be seen as a valid and replicable option for carbon stocks monitoring in tropical forests. Further improvements are planned to strengthen the cost effectiveness value/REDD+ suitability in the 2nd phase of EO4REDD. This 2nd phase will include [A] specific model developments per forest type; [B] measurements of afforestation, reforestation and natural regeneration processes and [C] study of Sentinel data series potential use.

Notre proposition de symposium court s’inscrit dans la continuité des recherches menées dans le pôle Codeus du laboratoire Trigone Cirel[1] et de l’Unité d’Apprentissage et de Formation continue des Adultes de l’Université de Liège (UAFA-ULg)[2]. Nous l’avons intitulé : gestes professionnels, propriété d’accompagnement et dispositif de validation des acquis ; trois exemples de couplage entre un dispositif de recherche et un dispositif de formation. Dans les trois contributions que nous proposons, il sera en effet question de l’association entre une activité de recherche qui se nourrit d’une activité de formation et d’une activité de formation qui exploite l’activité de recherche. Cela nous permettra de rendre compte de travaux menés en cours de formation à des échelles différentes : - à l’échelle du geste singulier de l’enseignant pour la première contribution ; - à l’échelle de la propriété d’accompagnement pour la deuxième ; - à l’échelle d’un dispositif de validation des acquis de l’expérience pour la troisième. Nous commencerons donc ce symposium en ciblant une préoccupation d’ordre micro-pédagogique pour en arriver, par la suite, à des préoccupations plus englobantes. Cela nous permettra de questionner, de différents points de vue, les modalités de collaboration entre dispositifs de formation et dispositifs de recherche, ce qui nous conduira à engager un débat autour des questions suivantes : -.comment les dispositifs de recherche mis en œuvre s’emparent-t-il des dispositifs de formation ? - comment le matériau de recherche est-il collecté, choisi, interprété, analysé, discuté ? - quels sont les cadres de références théoriques et méthodologiques mobilisés, à quoi servent-ils ? - comment l’activité de recherche est-elle distribuée entre les acteurs ? - peut-on parler de savoirs constitués et quels sont-ils ? - comment les dispositifs de formation exploitent-t-ils les dispositifs de recherche, comment s’en emparent-ils ? - etc [less ▲]

Introduction: Innovative plant biomass fractionation methods produce new feed additives that could modulate the pig intestinal microbial population. Material and methods: Such novel indigestible carbohydrates (CHO) were investigated for their prebiotic potential and their influence on Salmonella thyphimurium in a co-inocu¬lation in vitro fermentation model of the pig intestines. Inulin, cellobiose, pecto- (POS), iso-malto- (IMOS), xylo-oligosaccharides (XOS), and gluconic acid (GLU) were fermented by fecal microbes for 72h. Salmonella (7.3 log CFU/ml) were co-inoculated after 6h . Fer¬mentation kinetics was modeled and after 6, 12, 24 h, broth was analysed for short-chain fatty acid using HPLC and bacterial population using q-PCR. Results and discussion: Cellobiose was the fastest fermenting CHO followed by inulin and IMOS (P<0.01). After 6h, cellobiose yielded the highest SCFA production (684 mg/g) and lactate molar ratio (0.484). POS fermented slower. XOS and GLU were little fermented (150 and 175 mg SCFA/g after 24h). Nonetheless, GLU yielded the highest butyrate molar ratio (0.290 at 12h) (P<0.01). Although Salmonella counts did not differ, some CHO dis¬played obvious prebiotic properties, namely inulin and IMOS since they supported the highest growth of Lactobacilli and Bifidobacteria populations after 6 and 12h of fermen¬tation (8.18 to 8.56 log CFU/ml) (P<0.01). Cellobiose and GLU scored well for Lactobacilli too, but poorly for Bifidobacteria (6.41 to 6.92 log CFU/ml) (P<0.01). It is concluded that IMOS seem the most promising prebiotic but owing to their fermentation patterns yield¬ing high levels of lactate or butyrate, also cellobiose and GLU deserve further investigation in in vivo models.

In seismically-active regions, earthquakes may trigger landslides enhancing the short-to-long term slope denudation and sediment delivery and conditioning the general landscape evolution. Co-seismic slope failures present in general a low frequency - high magnitude pattern which should be addressed accordingly by landslide hazard assessment, with respect to the generally more frequent precipitation-triggered landslides. The Vrancea Seismic Region, corresponding to the curvature sector of the Eastern Romanian Carpathians, represents the most active sub-crustal (focal depth > 50 km) earthquake province of Europe. It represents the main seismic energy source throughout Romania with significant transboundary effects recorded as far as Ukraine and Bulgaria. During the last 300 years, the region featured 14 earthquakes with M>7, among which seven events with magnitude above 7.5 and three between 7.7 and 7.9. Apart from the direct damages, the Vrancea earthquakes are also responsible for causing numerous other geohazards, such as ground fracturing, groundwater level disturbances and possible deep-seated landslide occurrences (rock slumps, rock-block slides, rock falls, rock avalanches). ...

Reviewing the successive cognitive, operative and constructive models of architectural morphogenesis through time, the paper first recalls students and teachers in architecture how designers started experimenting digital design to reach self-generative, morphogenetic morphologies. Generally referred to as “non-standard architecture”, this innovative morphogenesis favours a new kind of spatial and architectural audacity but also generates three types of rupture: i) a rupture between form and structure; ii) a rupture in terms of process continuity and iii) a rupture in terms of multi-disciplinary collaboration. We consequently have to acknowledge the fact that, at a current state, non-standard architecture still struggles in terms of self-coherency and implementation, leaving a large amount of projects at their virtual, embryonic state especially in pedagogical contexts. We believe the challenge resides in overcoming the overly simplistic and reductionist appeal of purely formal and visual non-standard architecture: these morphologies should, on the contrary, be intrinsically defined by their form and structure relationship. We suggest such reconciliation should occur during the early stages of architectural education. Two experimental instruments, that perhaps constitute interesting renewed pedagogical models, are reported in this paper and we conclude by listing the remaining challenges when it comes to the teaching of architectural morphogenesis.

Perinatal hypoxic-ischemic encephalopathy (HIE) occurs in 1-8 cases per live 1000 births. Brain hypoxia and ischemia due to systemic hypoxemia and reduced cerebral blood flow (CBF) are the primary causes of neonatal HIE accompanied by gray and white matter injuries occurring in neonates. About 20% of affected newborns die in the postnatal period, and an additional 25% will sustain childhood disabilities. So far no medical treatment provides important neuroprotection against HIE. Studies of new neuroprotective agents in animal models of HIE may provide important information pertinent to the development of treatments for this pathological condition. Estetrol (E4) is a recently described estrogen with four hydroxyl-groups that is synthesized exclusively during pregnancy by the human fetal liver. It has important antioxidative activity. In this study, in vitro we defined antioxidative effect of E4 on primary hippocampal cell cultures, taken from newborn rat pups, before/after induction of oxidative stress. To examine oxidative stress and cell viability, lactate dehydrogenase (LDH) activity and cell survival (MTS) assays were performed on primary neuronal cell cultures. To study the neuroprotective and therapeutic effects of E4 in vivo neonatal HIE model of 7-day-old newborn rat pups was used. Rat pups body temperatures were examined along with their body and brain weights. Brains were studied at the level of the hippocampus and cortex. Intact cell counting and expressions of markers for neuronal cell viability (microtubule-associated protein-2 (MAP-2)), neurogenesis (doublecortin (DCX)) and angiogenesis (vascular-endothelial growth factor (VEGF)) were evaluated by histo- and immunohistochemistry. The serum levels of brain damage markers (S100B and glial fibrillary acidic protein (GFAP)) were measured by ELISA. Our results demonstrate for the first time that E4 has a significant neuroprotective and therapeutic effects. Also, E4 has powerful antioxidative and cell survival properties in vitro. It decreases the early gray matter loss and promotes neuro- and angiogenesis in vivo. Estetrol treatment has no effects on body weight, brain weight or body temperature. Taken together, E4 might become an important safe and physiological substance to treat neonatal HIE. [less ▲]

Neonatal hypoxic-ischemic brain injury remains a main problem of perinatal medicine. About 20% of affected newborns die in the postnatal period, and an additional 25% will sustain childhood disabilities mostly in the form of motor and cognitive delays. The nature of the deficits is dependent on the gestational age and severity of the insult, though it is s seldom reported in preterm infants. No medical treatment provides important neuroprotection against HIE. Studies in animal models of HIE may provide important information for the development of treatment for this pathological condition. Estetrol (E4) is a recently described estrogen with four hydroxyl-groups that is synthesized exclusively during pregnancy by the human fetal liver. In this study, we defined the antioxidative effect of E4 in primary hippocampal cell cultures taken from newborn rat pups (in vitro) and evaluated its neuroprotective and therapeutic potency in neonatal HIE model of the immature newborn rat (in vivo). Lactate Dehydrogenase (LDH) and cell survival (MTS) assays were performed on primary neuronal cell cultures. Rat pups body temperatures were examined along with their body and brain weights. Brains were studied at the level of the hippocampus and cortex.

Several recent studies about school mobility highlighted the significant decline of active modes and public transport's modal shares. Associated with this decline, it can be observed that distances between home and schools have been rising the last two decades. To develop appropriate policies alleviating the negative effects of the increased motorization in the school commute, a diagnosis of probable causes is required. To perform this diagnosis, we develop an accessibility-based methodology using data stemming from the Belgian national household travel (BELDAM) survey. Gamma-functions are calibrated to describe the use of different transport modes according to their relative travel times. Data from OpenStreetMap are used to describe the Walloon roads network in terms of the maximum allowed vehicle speed and length for each link. Properties of the network are modified to match with other transport modes. Maps of accessibility to schools are computed for each transport mode by merging the value of access time represented by isochrones and the calibrated gamma-functions. [less ▲]
