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.

No Indo-iranian formula was coordinating gods with demons, but another one, welle attested, was linking mortal men with gods. Initially, it was saying the solidarity between both groups, who were meeting on the sacrificial ground. Its use in Rigvedic and Avestan texts shows divergent evolutions. In India, men and gods go away from each other. In Iran, the original coordination, whose negative meaning is appearing, is inserted ina an always wider demonic list, which is included in a sentence using another inherited formula, whose theme was the crossing of enmities. During the evolution process of this formula, men go with the ancient *daiva- to demonisation. [less ▲]

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). ...

Les réformes institutionnelles de 1988-1989 ont transféré aux Communautés les compétences en matière d’enseignement. Pour la Communauté française, cette responsabilisation a très vite rimé avec la nécessité de réaliser d’importantes économies et donc d’importantes réformes structurelles. Une première vague de protestation secoue Bruxelles et la Wallonie en 1990 mais, cinq ans plus tard, un nouveau plan d’économies préparé par la socialiste Laurette Onkelinx, Ministre-Présidente de la Communauté française, en charge notamment de l’Education, donne naissance à un long et douloureux mouvement de protestation. Celui-ci semble matérialiser la rupture entre une base enseignante proche, selon les réseaux, du PS ou du PSC, et un Exécutif au sein duquel ces deux partis fonctionnent en coalition. Réduction des dépenses, suppression de trois mille postes, fusions d’écoles, tous les ingrédients sont réunis pour que la situation soit explosive. Elle va l’être d’autant plus – et cela marquera d’ailleurs durablement les esprits – que certaines manifestations de mécontentement vont s’exprimer avec violence, s’attaquer à des symboliques fortes (la Fête de la Communauté française en septembre 1995, le 1er mai 1996) et perturber la vie privée de la Ministre et de son entourage. Notre contribution s’inscrit dans le volet « images produites ». Elle s’interrogera sur le rôle des images dans la représentation que la presse écrite généraliste a donnée du mouvement enseignant et des enseignants eux-mêmes durant ce conflit. Grâce à certaines archives numérisées, le traitement du mouvement par l’audiovisuel public pourra, lui aussi, être abordé. La photographie de presse, la caricature et le reportage ont-ils contribué à présenter le mouvement enseignant de manière objective et dépassionnée ? Ont-ils au contraire – et jusqu’à quel point ? - intégré les clichés traditionnels véhiculés sur cette catégorie socio-professionnelle (conservatisme, attachement à de supposés « privilèges »…). Quelle image est renvoyée du syndicalisme enseignant ? Comment est mise en scène la relation triangulaire entre grévistes, ministre et public de l’école (parents et élèves) ? Quels sont le poids et le rôle dévolus à chacun ? Quelle est, spécifiquement, le traitement réservé au mouvement par un journal comme La Wallonie ? Comment a-t-il accompagné en images la rupture entre le monde enseignant, la CGSP et le parti socialiste, culminant le 1er mai 1996 ? [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 ▲]

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.

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 ▲]

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 ▲]

This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No piles effect or air entrance is considered in the study. The velocity field is measured by Large Scale Particle Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparisons of measured velocities between both spillways indicate low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is then fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity expressed from the relative pressure finally emphasizes that bottom pressure amplitudes are overestimated for the large spillway, while an averaging effect might operate for the pressure measurements on the small spillway.

We describe a new gait segmentation method based on the continuous wavelet transform to identify stride-by-stride gait cycles from measurements of foot-mounted three-dimensional (3D) accelerometers. The detection of such gait cycles is indeed a crucial step for an accurate extraction of relevant gait events such as heel strike, toe strike, heel-off, and toe-off. We demonstrate the ability of this segmentation method, used in conjunction with a validated extraction algorithm, to calculate the following gait (duration) parameters for each gait cycle during the gait of a healthy young subject and of an elderly subject with Parkinson’s disease (PD) in OFF and ON states: durations of (1) loading response, (2) mid-stance, (3) push-off, (4) stance, (5) swing, (6) stride, (7) step, and (8) double support phases. The experimental results show that the proposed method can extract relevant refined gait parameters to quantify subtle gait disturbances in subjects with PD. [less ▲]

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.

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.

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 ▲]

Ce symposium réunit des chercheurs et des praticiens d’une université belge et d’une université française autour du thème : « quelles recherches sur/pour les enseignements » ? 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 ▲]

Syntactic analyses describe grouping operations that explain how words are combined to form utterances. The nature of these operations depends on the approach. In a constituency-based approach, grouping operations are ordered, or stratified, part-whole relations. In a dependency-based approach, grouping operations identify a governor (or head), i.e. they are directed hierarchical relations between words. It is possible to convert a constituency tree into a dependency tree by dereifying the nodes, by identifying the governor and by removing the stratification of the part-whole relations. Polygraphs combine the two types of information into a single structure and are therefore a more powerful formalism. By relaxing constraints, polygraphs also allow to underspecify both kinds of information. [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.

In the context of fulfilling the Water Framework Directive requirements, the LIFE+ project Walphy allowed experimental restoration projects to be undertaken on two medium-size catchments of the Meuse basin in Wallonia (Belgium) between 2009 and 2014. Before undertaking sustainable rehabilitation measures, a multi-scale assessment of hydromorphological conditions (catchment, stream and site) was conducted. It was based on a variety of variables characterizing the river system and its geomorphic processes (e.g. sediment transport), along with human-induced disturbances (e.g. barriers to river continuity). The Bocq catchment has been subject to a large-scale restoration project through the removal or modification of 20 barriers (mainly old weirs), reconnecting the Bocq with the Meuse. In addition, 2.6 km of straightened courses were improved by restoring meanders or diversifying habitats through a wide range of rehabilitation techniques. The success of the restoration projects was evaluated on the basis of a multi-disciplinary monitoring. We compared hydromorphological parameters and biological diversity of benthic invertebrates, fish and macrophytes. 2-3 years post-rehabilitation, hydromorphology was significantly improved. Depending on the rehabilitation measures, the restoration effects observed for invertebrates and fish differ. Weir removal and restored meanders have resulted in the most positive effects, while habitat diversification has led to more contrasted results, depending on the level of ambition. The geomorphological monitoring has focused on the effectiveness of spawning gravel rehabilitation and the effect of barriers on sediment transport. Topographic surveys and the use of pebble tracers have highlighted a natural bedload transport following a weir removal. [less ▲]

The paper presents an integrated tool for dam-break hazard modelling. It is based on a two-dimensional, depth-averaged hydraulic model that uses a conservative and shock-capturing finite volume scheme on a Cartesian grid. The hydraulic model is designed so that different zones within the computation domain can be modelled with different spatial resolutions and/or different model enhancements (e.g. pressurised flows, sediment transport, etc.). The two-dimensional model can be coupled with lumped models that compute the water stage in reservoirs and the outflow discharge through hydraulic structures, in case of normal operating, failure of a valve or breaching processes. These features make hydraulic modelling versatile and computationally efficient. They enable the definition of different failure scenarios, which is of prominent importance given the uncertainty of such a phenomenon. If several hydraulic structures are involved, the procedure takes the behaviour of each structure into account. The sensitivity of the results with respect to the interactions between the flow and the terrain (roughness coefficient, collapse of buildings, breaching process) can be analysed. The results of the hydraulic model are handled thanks to a graphical user interface that provides one-, two- and three-dimensional views and animations of the unsteady flow-field and enables the understanding and verification of the results. Danger maps are generated based on the results of one or more ‘worst-case’ scenarios. In case of a complete risk analysis, the danger maps are combined with data on the exposure and vulnerability of elements at risk for the computation of the corresponding damage. [less ▲]

Cooperative organisations play an important role in the peacebuilding efforts undertaken in the wake of the Rwanda genocide in1994. The genocide tore apart and destroyed large parts of the country’s socio-economic and institutional foundations, its consequences are still evident. Coffee is the main source of income for approximatively 500.000 households. The paper aimed to analyze the impact of coffee cooperatives and the coffee washing stations in the peacebuilding socio-economic changes of coffee farmer’s members in Huye District, Southern Province of Rwanda. A research surveyed selected 70 small coffee farmers from 3 cooperatives to measure socio-economic development of coffee washing stations on the growers. Results reveal that cooperatives increase production and improve the socioeconomic households’ income (86.5%). Jobs are created for women and girls especially during the harvesting and the coffee processing (98.7%). When farmers are working together, a synergy is created among them, by disucussion, exchanging experiences, which avoide discrimination, conflict, division between antagonist ethnic groups Hutu and Tutsi (67.1%). Results reveal that coffee cooperatives promote a spirit of understanding each other and the tolerance between farmers (72.3%). Cooperatives provide loans to the members through the “rotating funds: Ibimina”. They also educate members through vocational trainings by enhancing and empowering farmers especially women and girls (97.1%). This is evidenced by the provision of adequate shelter, the observation of human rights, access to the medical insurance, school fees for children, undertaking entrepreneurial activities, unity and reconciliation between members, participating in the household’s incomes allocation. Cooperatives uses various strategies in peacebuilding such as working together to construct new schools and houses, land inheritance for women, clubs for peacebuilding and visiting each others (74.3%).

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 ▲]

Selon la loi de Pareto, 80 % des effets sont produits par 20 % des causes. Transféré au contexte universitaire, on dira que les petites différences de comportement, notamment langagier, entre enseignants conduisent à des effets sur les étudiants qui peuvent être fortement diversifiés. C’est cette observation qui nous a encouragé à développer les études micropédagogiques , c’est-à-dire l’observation fine de l’activité des enseignants pour saisir ce qui la caractérise et la rend plus ou moins « efficace » (le terme étant évidemment relatif et à définir en fonction des contextes, des objectifs poursuivis et des apprenants). Le principe méthodologique de l’étude micropédagogique consiste donc à combiner (1) l’analyse fine de l’activité enseignante et (2) ses effets auprès des apprenants. Dans le cadre de cette communication, nous présentons l’intégration d’un dispositif de recherche et d’un dispositif d’apprentissage situés dans cette perspective d’approche micropédagogique. Durant plusieurs cours, deux caméras filment simultanément d’une part l’enseignant qui réalise un exposé et d’autre part le groupe d’étudiants. Lors de la séquence pédagogique suivante, les apprenants visionnent le double film (en split screen) et le commentent collectivement, en reliant les observations sur l’activité de l’enseignant et les effets que cela a eu sur leur dynamique d’apprentissage. Il en ressort que plusieurs actions du formateur ont fort impact sur l’apprentissage et la motivation, notamment : les modes de gestion du groupe, la formulation des questions, les modes de réactions de l’enseignant aux interventions des participants, les types d’exemples choisis, l’utilisation des analogies ou encore la projection dans le passé et dans le futur. Selon la manière de procéder de l’enseignant, ils contribueront plus ou moins à l’apprentissage et à la dynamique motivationnelle des étudiants. Par cette démarche de recherche, les apprenants produisent à la fois de la connaissance scientifique et développent leur propre apprentissage sur les contenus de l’étude micropédagogique. [less ▲]

The paper introduces a new model for the motion about an oblate planet under the influence of the atmospheric drag. Both qualitative and quantitative insights are revealed, as well as closed-form equations of motion. The main tool consists in averaging the effects of both perturbations (oblateness and drag), and deriving the variational equations for the vectorial orbital elements. The model is singularity-free and may serve as an initial guess for control problems, as well as an analytic propagator. [less ▲]

The paper briefly presents the main features of a hydro-mechanical coupled finite element of interface. The mechanical problems takes into account the the detection of contact, the development of a contact pressure, the shearing and the relative sliding between two solids. A three-node discretisation of hydraulic problem allows the representation of fluid flows across and in the plane of the interface. The method involves a drop of pressure between each side of the interface and the inner medium. The hydro-mechanical couplings come from 1) the definition of the total pressure acting on each side of the interface according to the Terzaghi’s principle; 2) the dependence of the permeability on the gap variation; 3) the variation of the fluid mass stored within the gap.

Locality and place making as elements of social sustainability play a significant role in a world of growing globalization. More and more researchers and professionals realize that the identity of small communities is also constructed by modest heritage, responsible for a large part of the quality and social cohesion. Once we focus on the historical, social, cultural, ecological and physical meshwork, we transcend the solely focus on the object to explore the physical, emotional and experiential realities of place and how these are rooted in the individual and collective memory as they unfold in the everyday life. In the creation of a sustainable and resilient society the meaning and appropriation of that heritage is too important and too complex to restrict the significance of it purely to the artefact itself with its acknowledged architectural, historical or archaeological values. How can new meaning of place be enacted, created and negotiated in current times of migration and mobility? What is the status and role of modest heritage in small communities today? Does it still play a considerable role in the identity, quality and social cohesion of a region? How do we explore the intangible dimension of the tangible? How do we deal with the intangible and informal aspects of heritage? This paper concentrates on these issues in the complex urban countryside of the region of Flanders (Belgium). Flanders is a highly dense and post-industrialized area where the countryside is under an urbanized pressure. Within the fabric we detect numerous small-scale heritage as chapels, parsonages, ice-cellars, donjons, square farms and wind- and watermills. Possible relationships of heritage with its context will be tackled, explored and tested in different layers through particular cases within the strategy of storytelling as a spatial practice.

The competition in the field of storage racking structures is so that the companies proposing structural solutions for such structures are always looking for an optimisation of the structural elements, through the use of optimized thin wall members, and for an optimisation on site, by proposing easy and cheap connections to limit the time of construction. Within this framework, a simple connection with long bolts for tubular racking structures represents an interesting solution whose shear resistance is not covered by the rules provided by the current EC3. In order to verify the possibility to extend the formulations given in EC3 for connections between plates elements to this kind of connection solution in the present paper the results of an experimental campaign on 24 bolted connections, between hollow tube and long through bolts, are presented and analysed. In particular the attention is focused on the bearing failure mode around the tube’s hole due to bolt’s shank contact pressure. The performed analyses evidenced, preliminarily, that Eurocode 3 gives conservative values for the prediction of the bearing resistance. [less ▲]

The Solar Orbiter mission is composed of ten scientific instruments dedicated to the observation of the Sun’s atmosphere and its heliosphere, taking advantage of an out-of ecliptic orbit and at perihelion reaching a proximity close to 0.28 A.U. On board Solar Orbiter, the Extreme Ultraviolet Imager (EUI) will provide full-Sun image sequences of the solar corona in the extreme ultraviolet (17.1 nm and 30.4 nm), and high-resolution image sequences of the solar disk in the extreme ultraviolet (17.1 nm) and in the vacuum ultraviolet (121.6 nm). The EUI concept uses heritage from previous similar extreme ultraviolet instrument. Additional constraints from the specific orbit (thermal and radiation environment, limited telemetry download) however required dedicated technologies to achieve the scientific objectives of the mission. The development phase C of the instrument and its sub-systems has been successfully completed, including thermo-mechanical and electrical design validations with the Structural Thermal Model (STM) and the Engineering Model (EM). The instrument STM and EM units have been integrated on the respective spacecraft models and will undergo the system level tests. In parallel, the Phase D has been started with the sub-system qualifications and the flight parts manufacturing. The next steps of the EUI development will be the instrument Qualification Model (QM) integration and qualification tests. The Flight Model (FM) instrument activities will then follow with the acceptance tests and calibration campaigns. [less ▲]

Algorithmic and computer programming in the bachelor’s degree is a course that demands a large involvement of students in performing non-standard exercises. This practical aspect is incompatible with classical ex cathedra course. It is the reason why we implement a blended learning approach much more responsive to students in a bachelor class of Bio Engineering at the Gembloux Agro Bio Tech Faculty (University of Liege, Belgium). This course alternates theoretical classes, take-home lessons with the help of online pedagogical resources and video and debriefing sessions where students have the possibility to benefit from teacher’ support. In doing so, the students are better prepared for the examination. They also gain in confidence and motivation.

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.

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.

Because nowadays structural engineers are willing to use or at least understand nonlinearities instead of simply avoiding them, there is a need for numerical tools performing analysis of nonlinear large-scale structures. Among these techniques, the harmonic balance (HB) method is certainly one of the most commonly used to study finite element models with reasonably complex nonlinearities. However, in its classical formulation the HB method is limited to the approximation of periodic solutions. For this reason, the present paper proposes to extend the method to the detection and tracking of codimension-1 bifurcations in the system parameters space. As an application, the frequency response of a spacecraft is studied, together with two nonlinear phenomena, namely quasiperiodic oscillations and detached resonance curves. This example illustrates how bifurcation tracking using the HB method can be employed as a promising design tool for detecting and eliminating such undesired behaviors. [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.

The Arlon conference brought together lecturers willing to share and discuss aspects of their practice of “controversies”, seen as a teaching/learning method suited to the contextual needs and demands of higher education environmental studies. The paper contributes to this joint reflective effort by providing conceptual tools helping to interpret the practice, to question what it puts at stake and to detect, from a pedagogical viewpoint, key issues and upcoming questions. The contribution falls within the Conference's aim n°2: “share theories or conceptual propositions that make it possible to equip the teaching approaches and to give them theoretical and methodological foundations” (Program Arlon Conference 2014, p. 2).

Introduction : Le cancer du sein ainsi que ses traitements sont à l'origine de nombreux effets secondaires indésirables. L'objectif de l'étude est de déterminer les bénéfices éventuels, tant sur le plan physique que psychologique, d’un programme de revalidation multidisciplinaire chez des femmes ayant été traitées pour un cancer du sein. Méthodologie : 122 patientes ont été recrutées, 61 faisant partie du groupe contrôle et 61 du groupe traité. Celui-ci a bénéficié d’une revalidation de trois mois comprenant un entraînement physique supervisé et diverses sessions psycho-éducatives. Les évaluations, effectuées avant et après la prise en charge, ont inclus des mesures anthropométriques et de composition corporelle, une évaluation des capacités fonctionnelles et différents questionnaires. Résultats : Au terme des trois mois, l’état de santé (qualité de vie), le rôle fonctionnel, l’état émotionnel et les fonctions physiques, cognitives et sociales s’améliorent significativement au sein du groupe traité. Cette observation s’applique également aux symptômes de fatigue, d'insomnie, de douleur, de dyspnée, de perte d'appétit, d’anxiété et de dépression ainsi qu'aux paramètres physiques obtenus par l'intermédiaire des évaluations fonctionnelles. Au sein du groupe contrôle, ces améliorations n’apparaissent pas et une augmentation significative de l'indice de masse corporelle et du pourcentage de graisse corporelle est observée. Conclusion : Cette étude préliminaire montre ainsi la faisabilité et les effets bénéfiques d’une prise en charge multidisciplinaire chez des femmes au terme de leurs traitements pour le cancer du sein.

A new signal processing algorithm is developed for quantifying heel strike (HS) and toe-off (TO) event times solely from measured heel and toe coordinates during overground walking. It is based on a rough estimation of relevant local 3D position signals. An original piecewise linear fitting method is applied to these local signals to accurately identify HS and TO times without the need of using arbitrary experimental coefficients. We validated the proposed method with nine healthy subjects and a total of 322 trials. The extracted temporal gait events were compared to reference data obtained from a force plate. HS and TO times were identified with a temporal accuracy ± precision of 0.3 ms ± 7.1 ms, and –2.8 ms ± 7.2 ms in comparison with reference data defined with a force threshold of 10 N. This algorithm improves the accuracy of the HS and TO detection. Furthermore, it can be used to perform stride-by-stride analysis during overground walking with only recorded heel and toe coordinates. [less ▲]

Platelets have known roles in coagulation, inflammatory processes, and immunity modulation; they also have ‘‘restorative’’ properties. Indeed, during degranulation, platelets release different cytokines and growth factors (VEGF, PDGF, TGF-B, IGF-I, and HGF) that promote angiogenesis, tissue remodeling (bone, skin, muscle, tendon, etc.), and wound healing. PRP is obtained by centrifuging autologous blood to obtain a concentration of platelets, usually between 3 and 10 times that of whole blood, depending on the isolation method. For this reason, different PRP preparation techniques cannot provide a consistently identical final product, but there is currently no international consensus on this issue. Overall, PRP could be an attractive therapeutic option for treating chronic musculoskeletal conditions, such as tendinopathy or plantar fasciitis. Tendons do not have a high metabolic index. Growth factors released by platelets promote tenocyte proliferation, stimulate angiogenesis and have analgesic properties. Thus it could stimulate and accelerate tissue regeneration in animal models. In addition to PRP, optimal tissue quality requires the application of mechanical loads. PRP should be considered for chronic tendinopathies. Indeed, the goal is to initiate an acute inflammatory reaction that quickly moves on to the proliferative phase that involves collagen synthesis. The latter is necessary for appropriate tendon healing. PRP should therefore not be used for acute tendinitis or tenosynovitis. Even if most of the preclinical studies showed that PRP stimulates the tendon healing process, clinical series remain more controversial. Based on literature and our clinical experience, we suggest some ideas for improving this treatment. Optimization of the technique for collecting the PRP is paramount. Different risk factors must be corrected before infiltration, and chronic tendinopathies must be carefully selected. Finally, post-infiltration rehabilitation remains absolutely necessary. Standardisation of the use of PRP remains necessary in order to optimise the results. [less ▲]

When the control is turned off, the trajectories have not reached the target and they subsequently evolve according to the free motion dynamics. In this context, we show that the problem can be formulated as a finite-horizon optimal control problem which relies on the notion of isostables. For linear and nonlinear systems, we solve this problem using Pontryagin’s maximum principle and we study the relationship between the optimal solutions and the geometry of the isostables. Finally, optimal strategies for choosing the magnitude and duration of the control are considered. [less ▲]

This paper addresses the problem of model reduction for dynamical system models that describe biochemical reaction networks. Inherent in such models are properties such as stability, positivity and network structure. Ideally these properties should be preserved by model reduction procedures, although traditional projection based approaches struggle to do this. We propose a projection based model reduction algorithm which uses generalised block diagonal Gramians to preserve structure and positivity. Two algorithms are presented, one provides more accurate reduced order models, the second provides easier to simulate reduced order models. [less ▲]

This paper proposes a new pixel-based background subtraction technique, applicable to range images, to detect motion. Our method exploits the physical meaning of depth information, which leads to an improved background/foreground segmentation and the instantaneous suppression of ghosts that would appear on color images. In particular, our technique considers certain characteristics of depth measurements, such as failures for certain pixels or the non-uniformity of the spatial distribution of noise in range images, to build an improved pixel-based background model. Experiments show that incorporating specificities related to depth measurements allows us to propose a method whose performance is increased with respect to other state-of-the-art methods. [less ▲]
