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. The teacher no longer simply transmits the knowledge but assists the students in their reflection process and their mastering of programming tools [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.

In order to increase the production of power on small satellites, large solar panels are commonly deployed and, in some cases, reflectors are added to improve the concentration factor on solar cells. In this work, reflectors are deployed by the means of compliant mechanisms known as tape springs. Their attractive characteristics are, among others, their passive behaviour, their self-locking capacity, their elastic deformations and their robustness. It is shown here through parametric studies that the behaviour of a tape spring is mainly governed by its geometry. Thus, for each specific application, its dimensions must be determined in order to minimise two critical features: the maximum stresses affecting the structure and the maximum amplitudes of motion during deployment. In this paper, an optimisation procedure is proposed to meet these requirements. [less ▲]

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 ▲]

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 ▲]

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.

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.

In the frame of a regional project evaluating the geothermal potential of the Wallonian Region of Belgium, the Hockai Fault Zone has been identified as one of the most interesting targets. It is a seismically active fault zone that hosted the largest historical earthquake in Northwestern Europe, the M6-6.5 Verviers event in 1692 as well as a swarm of small earthquakes that was recorded in 1989-90. On the surface, the presence of the fault zones is marked by a series of geomorphic features, such as several landslides near the borders in the northern part, repeated NW-SE oriented scarps all along the Eastern border (over a distance of 40 km), river diversions and captures with formation of paleo-valleys....

In the present paper, isolated response curves in a nonlinear system consisting of two masses sliding on a horizontal guide are examined. Transverse springs are attached to one mass to provide the nonlinear restoring force, and a harmonic motion of the complete system is imposed by prescribing the displacement of their supports. Numerical simulations are carried out to study the conditions of existence of isolated solutions, their bifurcations, their merging with the main response branch and their basins of attraction. This is achieved using tools including nonlinear normal modes, energy balance, harmonic balance-based continuation and bifurcation tracking, and global analysis. [less ▲]

In this work, an electricity zone with 100% renewables is simulated to determine the optimal sizing of generation and storage capacities in such a zone. Using actual wind output data, the model evaluates the economic viability of a power-to-fuel storage technology that combines water electrolysis, CO2 capture and methanol synthesis. The main advantage of using methanol as an energy carrier is that liquid fuels are suitable for (long-term) energy storage thanks to their high energy density. The levelized electricity cost projection by 2050 equals 83.4 €/MWh in the base case configuration. The effects of storage round-trip efficiency and the storage unit lifetime are quantified and their impacts on the electricity cost discussed. Additional benefits of using methanol as a fuel substitute may be taken into account in further work. [less ▲]

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 ▲]

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 ▲]

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.

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). ...

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 ▲]

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.

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 ▲]

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 ▲]

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.

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.

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 ▲]

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.

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 ▲]

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.

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 ▲]

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.

Forage legumes (FL) are used in tropical countries to feed pigs, either by reducing allowance of well-balanced diets and supplementing with FL or by incorporating FL in unbalanced fibre-rich diets. The impact of both strategies on animal and economical performances was studied in 2 growth experiments. In Exp. 1, 4 groups of 8 growing pigs (25.5 +- 4.2 kg) were fed under one of 4 dietary treatment: a well-balanced diet (CONTROL) ad libitum or 80% of the ad libitum level of CONTROL + ad libitum freshly cut foliage of one of 3 FL species (Vigna unguiculata, Stylosanthes guinanensis, or Psophocarpens scandens). Similarly, in Exp. 2, 4 groups of 6 pigs (22.6 +- 3.7 kg) were fed one of 4 experimental diets: the well-balanced diet (CONTROL), an unbalanced traditional diet rich in fibre and made of bran, brewers grain, and corn (TRAD) or 80% TRAD diet supplemented with 20% of one of 2 FL hays (V. unguiculata or S. guinanensis). Animals were regularly weighed and feed intake was monitored. After 90d, animals were slaughtered and carcass composition and economic traits were recorded to calculate production costs and economical value. In addition, nutritive value of the FL and the diets was assessed by means of an in vitro model of the pig digestive tract combining an enzymatic hydrolysis to a fermentation with a fecal inoculum. Results indicate that pigs fed diets with FL (Exp.1) and TRAD with and without FL (Exp.2) had reduced ADG, final live and carcass weights (P<0.05) compared to CONTROL pigs. Surprisingly , dry matter intake (DMI) was also reduced by 10% with those diets compared to CONTROL (P<0.001) in both experiments. In Exp. 1, FCR and carcass dressing were not affected by the 20% reduction in CONTROL diet and supplementation with fresh FL, while in Exp. 2 those parameters were negatively affected in TRAD with and without FL compared to CONTROL pigs. In vitro data showed that differences in nutritive values explained most differences in growth performances and carcass traits, but not the decrease in intake, since passage rate and voluntary intake are not taken into account in the in vitro model. Economical assessment showed that fresh foliage of FL could increase incomes, as long as their production costs remain marginal, but the incorporation of FL hays could not improve economical performances in pigs fed traditional unbalanced fibre-rich diets.

The use of Geographic Information Systems within the field of archaeology has been demonstrated through numerous scientific studies in the past. However, such systems do not usually encompass all the characteristics of the archaeological data. Since 2009, the Geomatics Unit of the University of Liège works on the development of a robust, flexible and dynamic Archaeological Information System. The interdisciplinary research group focuses on the development of a conceptual data model based on the general characteristics of archaeological data namely its spatio-temporal, heterogeneous, multimodal and imperfect character. The following paper exposes latest output and especially the integration of archaeological data ambiguity [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 ▲]

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.

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.

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 ▲]

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%).

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 ▲]
