The crashworthiness capability of an aircraft structure is dependent on its ability to attenuate crash loading via the controlled deformation of energy absorbing devices. An energy-based constitutive relation was employed to model the behaviour of carbon fibre reinforced epoxy resin composite material under crush loading. Each of the damage modes in the fibre and matrix was treated separately with its own damage initiation and progression relationships as well as a damage parameter that tracks damage progression. Each damage parameter dictates the reduction in stiffness in the respective principal loading directions. This model was implemented for a 3D solid brick element in contrast to shell-based formulations currently available. Crushing composite structures were modelled and the results validated against experimental data. The force-displacement response / specific energy absorption and the failure modes obtained from the simulation show that the underlying physics of the crushing have been captured by the proposed model but that further work is required for reliable quantitative correlation.

La « Bleue Mixte » (BM) est une race à petit effectif localisée de part et d’autre de la frontière franco-belge. Menacée de disparition, elle bénéficie d’un projet transfrontalier BlueSel soutenu par le programme européen INTERREG IV et les autorités françaises et wallonnes. L’objectif de ce projet est d’assurer la conservation, la sélection et la promotion de la BM. L’un des volets du programme a consisté à étudier la rentabilité économique des troupeaux BM. Il s’est appuyé sur un réseau de 16 fermes de références mis en place fin 2008 jusque mi 2012. La collecte des données techniques et économiques sur les 4 années comptables de 2007 à 2010 a reposé sur la méthodologie mise en oeuvre au sein du dispositif français des Réseaux d’élevage. Les exploitations BM ont été regroupées selon deux systèmes, herbivore et polyculture-élevage, et comparées aux exploitations laitières Prim’Holstein (PH) du Réseau d’élevage de Nord-Picardie. Les résultats démontrent la capacité des éleveurs de vaches BM à obtenir de bonnes performances économiques malgré de plus faibles productivité laitière (4225 l/VL) et taux (3,70 % de MG et 3,22 % de protéines), et un moindre prix du lait, grâce notamment à une conduite de troupeaux bien maîtrisée, des surfaces fourragères très bien valorisées, et la mixité lait-viande très affirmée de la race qui atténue les fluctuations du prix du lait. En système herbivore, les exploitations BM s’avèrent économes et autonomes avec une excellente valorisation des prairies. En système de polyculture-élevage, les troupeaux sont conduits de façon à peine plus intensive qu’en système herbivore, contrairement aux troupeaux PH. [less ▲]

The present paper addresses the experimental identification of a simplified realisation of a solar array structure in folded configuration. To this end, a nonlinear subspace identification technique formulated in the frequency domain, referred to as the FNSI method, is exploited. The frequency response functions of the underlying linear structure and the nonlinear coefficients are estimated by this approach. Nonlinearity is caused by impacts between adjacent panels and friction and gaps appearing in their clamping interfaces. This application is challenging for several reasons, which include high modal density and the complicated nature of the involved nonlinear mechanisms. [less ▲]

L’article aborde la question du recyclage des quartiers périurbains existants sous l'angle énergétique. Deux leviers d’actions sont mobilisés à cet effet : la forme urbaine, qui est étudiée en complémentarité de l’échelle du bâtiment individuel, et la mobilité, car l’étalement urbain est entretenu et favorisé, en grande partie par la dépendance à la voiture individuelle. Deux indicateurs principaux (les besoins de chauffage de différents types de formes périurbaines et un indice de performance des déplacements) sont développés et discutés pour mettre en évidence les scénarios de renouvellement les plus adaptés et répondre à deux questions : « comment intervenir dans les quartiers périurbains existants ? » et « où intervenir ? ». Des pistes concrètes visant à l’opérationnalisation d’un « renouvellement périurbain » plus durable sont ensuite proposées. [less ▲]

Les structures publiques de quartier mises en place dans le cadre de cette politique pourraient en effet jouer un rôle d’accélérateurs de la transition de ces quartiers. Elles ont le potentiel pour cela, notamment grâce au réseau social qu’elles développent au sein de la population locale, sans l’engagement de laquelle les pouvoirs publics peuvent bien peu de choses.

Performance-based design in fire engineering leads to increasing demand for advanced temperature-dependent material models for the load bearing materials used in building structures. These models must be valid in natural fire situations including cooling down phase and must be sufficiently robust for complex numerical calculations such as, for example, the analysis of tensile membrane action in composite slabs. Although structural concrete is widely used in civil engineering, proper modelling of its thermo-mechanical behaviour remains a challenging issue for engineers mainly because of the complexity of the phenomena that result from the microcracking process in this material and because of the necessity to ensure the numerical robustness of the models. This paper presents a new multiaxial concrete model based on a plastic-damage formulation and developed to meet the specific requirements of structural fire engineers and researchers. The model, which incorporates an explicit term for transient creep strain and encompasses a limited number of material parameters, has been implemented in a finite element software dedicated to the nonlinear analysis of structures in fire. The paper presents a series of numerical simulations conducted to highlight the model ability to capture the main phenomena that develop in concrete under fire (permanent strains, degradation of the elastic properties, unilateral effect) as well as its ability to be used for the fire analysis of large-scale structural elements. As an example, the new concrete model is used in the numerical analysis of a full scale fire test on a composite steel-concrete slab and it is shown that the computed and measured results agree.

The soft X-ray thermal emission of η Carinae varies strongly around the periastron, following the orbital period of 5.5 yr. We studied the hard X-ray non-thermal emission of η Car using new INTEGRAL observations taken close to periastron. We showed that the hard X-ray emission is very likely to be associated with η Car, and not with any other source found within the INTEGRAL error circle. We also showed that the 3-σ detection during the soft X-ray minimum is consistent with a hydrogen column density that does not exceed 6×10[SUP]23[/SUP] cm[SUP]-2[/SUP]. [less ▲]

During recent years some non-thermal radio emitting OB stars have been discovered to be binary or multiple systems. The non-thermal emission is due to synchrotron radiation that is emitted by electrons accelerated up to high energies. The electron acceleration occurs at the strong shocks created by the collision of radiatively-driven winds. Here we summarize the available radio data and more recent observations for the binary Cyg OB2 No. 9. We also show a new emission model which is being developed to compare the theoretical total radio flux and the spectral index with the observed radio light curves. This comparison will be useful in order to solve fundamental questions, such as the determination of the stellar mass-loss rates, which are perturbed by clumping. [less ▲]

Different scenarios try to explain the X-ray production in the O-type star wind (magnetic confinement, embedded shocks…) and their plasma temperature distribution. In this context, we have developed a new modeling code which computes synthetic spectra as a function of plasma temperature, abundances, and localization of the X-ray emitting shell in the wind. Then we combine several synthetic spectra in order to fit the observed high-resolution spectra. Our preliminary results on ζ Puppis reveal a non-porous wind as well as non-solar abundances for the CNO elements. More important, an extended region with a low temperature plasma begins to emit close to the star surface while small shells with hotter temperature plasmas emit farther in the wind. [less ▲]

We present the results from two optical spectroscopic campaigns on colliding-wind binaries (CWB) which both occurred in 2009. The first one was on WR 140 (WC7pd + O5.5fc), the archetype of CWB, which experienced periastron passage of its highly elliptical 8-year orbit in January. The WR 140 campaign consisted of a unique and constructive collaboration between amateur and professional astronomers and took place at half a dozen locations, including Teide Observatory, Observatoire de Haute Provence, Dominion Astrophysical Observatory, Observatoire du Mont-Mégantic and at several small private observatories. The second campaign was on a selection of 5 short-period WR + O binaries not yet studied for colliding-wind effects: WR 12 (WN8h), WR 21 (WN5o + O7 V), WR 30 (WC6 + O7.5 V), WR 31 (WN4o + O8), and WR 47 (WN6o + O5). The campaign took place at Leoncito Observatory, Argentina, during 1 month. We provide updated values of most of these systems for the orbital parameters, new estimates for the WR and O star masses and new constraints on the mass-loss rates and colliding wind geometry.

We review our knowledge of the mixing properties of magnetic OB stars and discuss whether the observational data presently available support, as predicted by some theoretical models, the idea that magnetic phenomena favour the transport of chemical elements. A (likely statistical) relationship between enhanced mixing and the existence of a field has been emerging over the last few years. As discussed in this contribution, however, a clear answer to this question is presently hampered by the lack of large and well-defined samples of magnetic and non-magnetic stars. [less ▲]

Six O-type stars were observed continuously by the CoRoT satellite during a 34.3-day run. The unprecedented quality of the data allows us to detect even low-amplitude stellar pulsations in some of these stars (HD 46202 and the binaries HD 46149 and Plaskett's star). These cover both opacity-driven modes and solar-like stochastic oscillations, both of importance to the asteroseismological modeling of O stars. Additional effects can be seen in the CoRoT light curves, such as binarity and rotational modulation. Some of the hottest O-type stars (HD 46223, HD 46150 and HD 46966) are dominated by the presence of red-noise: we speculate that this is related to a sub-surface convection zone. [less ▲]

We present an automated tool for measuring atmospheric parameters (T_eff, log(g), [Fe/H]) for F-G-K dwarf and giant stars. The tool, called GAUFRE, is written in C++ and composed of several routines: GAUFRE-RV measures radial velocity from spectra via cross-correlation against a synthetic template, GAUFRE-EW measures atmospheric parameters through the classic line-by-line technique and GAUFRE-CHI2 performs a chi^2 fitting to a library of synthetic spectra. A set of F-G-K stars extensively studied in the literature were used as a benchmark for the program: their high signal-to-noise and high resolution spectra were analysed by using GAUFRE and results were compared with those present in literature. The tool is also implemented in order to perform the spectral analysis after fixing the surface gravity (log(g)) to the accurate value provided by asteroseismology. A set of CoRoT stars, belonging to LRc01 and LRa01 fields was used for first testing the performances and the behaviour of the program when using the seismic log(g). [less ▲]

Interest for near-infrared (NIR) spectroscopy of massive stars has been dramatically increasing over the last decade. Because it allows one to observe objects inaccessible at optical wavelengths due to absorption, the infrared domain offers a privileged window to study highly extinguished objects. Yet, a detailed calibration of the massive star properties at NIR wavelength is still missing. Following the lines of the work of Repolust et al. (2005), we have acquired high resolution spectroscopy of several nearby massive stars using VLT/CRIRES, focusing on spectral lines of interest in the J, H, K, and L bands. In this work, we present the earliest results of our quantitative spectroscopic analysis of the main sequence stars in our sample. Using the unique combination of a genetic algorithm approach with the state-of-the-art non-LTE atmosphere model FASTWIND, we compare the stellar and wind properties as derived from the optical and the NIR regime.

Ludico-symbolic coups and assassination attempts, make-believe funerals and degeneration of trials into grotesque rhetorical jousting : everywhere throughout Europe and the United States in the mid sixties, political happenings thrived. The acts/performances, which were for the most part carried out by groups or individuals close to the Marxist and pacifist student protest movement, can’t be dissociated from a situationnist understanding of the urban milieu, transformed into one large stage for militant theatre. Founded on the principal of diversion and provocation, these actions quickly led to inflation and overbidding. Caught in a hectic whirl which forced them to always push the limit further in order to evade, if only temporarily, a process of institutionalisation that threatens any act of provocation, they soon begin to loose their political effectiveness. Born from a common political and artistic origin as the leaders of the student left movement, several “terrorist” groups harden their tone at the beginning of the seventies and perpetrate acts of violence with a revolutionary intention. Breaking away from the theatrical and ludic student activity while also retaining their situationnist obedience and a certain theatrical conception of the urban place, these armed groups think up actions in the beginning of the seventies which induce a rupture in the performative and theatrical tradition of the end of the sixties. These acts have been the subject of in depths studies by authors who, however conscious of the theatrical origins of the actions of the extreme left terrorists, refer to a terminology which imposes a distinction between action (or happening/performance) and “terrorist” acts. On the basis of this terminological distinction, we will demonstrate not only that these actions of the beginning of the seventies must be considered in a direct lineage with the political-theatrical creation of the end of the sixties, but that they also offer a first escape route, politically efficient, to the inflation which threatens any act of provocation. If the actions of the RAF, the Red Brigades or the Weathermen evade institutionalisation which threatens any act of provocation, they nevertheless remain politically unsustainable and condemn those who imagine them as well as those who execute them to an inevitably tragic ending, incompatible with the pursuit of creative practice. This paradigm will guide us in identifying some more recent creative processes (fake conferences of the Yes Men, shows/performances of Leo Bassi) which try to overcome in turn the political precariousness of their predecessors in endowing themselves with an (auto)reflexive dimension. Beyond their heterogeneity, these actions/shows shall thus be perceived as objects which surpass the act of provocation, inevitably destined to wear out. Because, in actively implicating the spectator to a point where he becomes a full fledge component of an engaged and reflexive creative process, these practices reinstate the politico-theatrical performance in its indispensable efficiency.

A main challenge for philosophers of the late nineteenth and early twentieth century was to construct judgements as acts of decision or position (thesis) rather than as acts of combination or synthesis. Let us call this the thetic view. Franz Brentano (1838–1917) is usually regarded as the best supporter of this view, since he takes advantage of the Kantian-Herbartian notion of ‘position’ (Setzung) to break with the traditional definition of judgement as symplokè (Martin 2006, 64 sq.; see Brentano 2008, 335). Generally speaking I think this usual line of interpretation is quite cor- rect, yet it could benefit from a more detailed account of the Brentano reception. What I would like to suggest is this: At stake in Brentano’s legacy is not just the rejection of the synthetic view but also the way in which the thetic dimension is itself conceived. There are, in fact, various ways of constructing judgements as thetic or positional phenomena. Brentano’s notion of ‘existential assertion’ is not the only way to do so. [less ▲]

During the second half of the 2nd century B.C., the city of Bargylia, in Caria, undertook a major reorganization of the cult of Artemis Kindyas, who manifested herself to help the city when it was threatened by war. A few remarkable inscriptions provide evidence of the regulations designed to « increase the honours » of the goddess, which mainly consist in making an ox sacrifice more splendid. Less than a century beforehand, a similar situation is observed in the cult of Artemis Leukophryene in Magnesia of the Meander, and of Artemis Hiakynthotrophos in Cnidus. Based on these three examples, this paper aims at showing how these epiphanies were used to settle a given deity into its function of patron deity of the city, both from an external and from an internal point of view.

The problems of productivity, predictability and quality in design and delivery of the building product are well documented. Prefabrication, process reengineering and digitalization are proposed as potential solutions to address these issues. One issue that is rarely addressed, however, is the management of the changes required to move from existing to a new paradigm of practices. Organization of work in construction, as opposed to other industries, has barely evolved in the last centuries. The research project studies the impact of the introduction of a new high-rise building construction system and BIM related technologies on the organization of work within a multi- residential project. The aim is to develop a concept of operation on how to reorganize work process within and between practices and trades. Ethnographic methods were used to identify issues regarding the management of information, the organization of work and the perceptions regarding BIM associated technologies and tools such as electronic tablets. Benchmarking and lean production tools such as value stream mapping were also utilized to identify problems of productivity and waste. Waste related to poor management of workflows and information flow was a major issue and had a strong impact on productivity. Contractual context in which there are no incentives for professionals and trades to improve their overall performance (no share responsibilities and fragmented obligations) was identified as the principal obstacle to changes in existing practices. Traditional project management practices proved to be inefficient to compensate the lack of coordination and collaboration between the project stakeholders. However, even if the use of BIM proved to be impractical in this context, tablets were well received as a way to improve collaboration and coordination of the work. A concept of operation was derived from the lessons learned that will be validated in the next pilot project. [less ▲]

La tradition liégeoise reste attachée à la personne de l’évêque Étienne (901-920) qui, à l’aube du Xe siècle, montait sur le siège de saint Lambert. Son œuvre a joui d’une renommée certaine au fil des siècles . Elle a connu un grand succès mesurable à l’aune des copies manuscrites dont elle a fait l’objet. On reconnaît désormais à cet évêque un rôle non négligeable dans la diffusion d’un procédé musical mis au point, dans le courant du IXe siècle, dans les abbayes d’Elnone et de Saint-Thierry de Reims. Pourtant, Étienne de Liège n’a, de toute évidence, pas fait école dans la cité mosane . On douta même longtemps de la part qui fut effectivement la sienne dans la composition de ces œuvres. Cet article s'interroge sur les motifs de cette remise en cause des qualités littéraires et musicales du dernier évêque carolingien liégeois. Quelle image ce prélat laissa-t-il à ses ouailles et à ses successeurs ? Quelle influence exerça-t-il réellement sur la production musicale et liturgique ultérieure ? Notger contribua-t-il à la diffusion de son œuvre ? Cet article propose quelques éléments de réponses à la lumière d'une étude de la tradition manuscrite de l'office de la Trinité. [less ▲]

Extreme floods of the river Meuse were simulated based on a detailed 2D unsteady hydraulic model. As part of a coordinated transnational modeling program, the study area considered here extends from Ampsin (Belgium) to the Belgian-Dutch border. The results of the present simulations are passed as upstream boundary condition to a second hydraulic model simulating the same flood scenarios in the Meuse in the Netherlands. In the simulations discussed here for the Belgian part of the Meuse, high accuracy and high resolution data were used to represent the main riverbed and the urbanized floodplains. The operation of all influencing mobile dams was represented in the model. The considered flood scenarios include the 100-year flood in the present situation (Q100), as well as two more extreme floods: Q100 + 15 % and Q100 + 30 %. These values correspond to return periods of the order of, respectively 300 and 1000 years in the present climate; but, according to a transnational climate change scenario in the Meuse basin, they may also be considered as estimates of the 100-year flood in 2050 and 2100. The computations have shown a very limited damping of the flood wave in the study area, not exceeding approximately 1 % of the peak discharge for Q100 and Q100 + 15 %, and reaching about 3 % for Q100 + 30 %. Compared to Q100, increases in the flood levels for Q100 + 15 % and Q100 + 30 % are, respectively, in the ranges 0.5-0.9 m and 1.0-1.8 m. Comparisons with the results from previous steady simulations revealed discrepancies not exceeding 5 cm for Q100 and Q100 + 15 %, and reaching a maximum of approximately 30 cm for Q100 + 30 %. Hence, from the perspective of the variation in peak discharge and flood levels, the study concludes that running the hydraulic model in steady mode is reasonable; although some differences occur in terms of inundation extents. The 2D unsteady model constitutes also a tool of primary interest, which is readily available to design and evaluate protection measures for flood-prone areas such as in the city of Liege. [less ▲]

Garlic has been used worldwide for centuries for its taste but also for its health benefits. Garlic's therapeutic compounds are mostly organosulfur compounds, recognized for their antioxidant, anticancer, anti-inflammatory and antimicrobial activity and their effect on cardiovascular diseases (reviewed by Block, 2010). When the cloves are crushed, allicin is synthesized as the vacuolar enzyme alliinase meets its substrate, the cytoplasmic alliin. Allicin is unstable and undergoes rearrangements to form three main groups of derivatives: allyl sulfides, ajoenes and vinyldithiins. The garlic processing method has a major influence on the products released both in terms of chemical composition and yields. For example, the type of medium (aqueous or oily) and the temperature can favour the formation of specific compounds. Our work aims at studying the influence of - the garlic origin, - the reaction conditions and - the extraction procedures (solvent, microwaves) on the organosulfur compounds formed. Particular attention is given to the stereochemistry and the stability of the compounds. Better understanding of the formation of high value natural molecules is important in order to lead further studies on the biological activity of the compounds or to use them as nutraceuticals.

In this chapter, we show that two-dimensional oscillation codes help us to improve our knowledge of the effects of rapid rotation on acoustic (p) and gravity (g) modes. We first discuss how to solve the full problem of stellar oscillations in rapidly rotating stars by including the effects of the Coriolis force as well as those of the centrifugal distortion. We illustrate the development and the validation of a 2-D code using the Two-dimensional Oscillation Program (TOP) as an example. We then describe what strategies are being developed to explore the p- and g-mode spectra, how effective these methods are, and what intrinsic difficulties they face. In the last part of this chapter, we present results obtained with these techniques. [less ▲]

Dans un contexte d’abandon ou négligence du secteur agricole par le pouvoir public, cette étude cherche à analyser la contribution de l’activité non agricole sur la réduction de la pauvreté et des inégalités dans le territoire de kabare dans la province du Sud-kivu. La présente étude se focalise sur deux groupements du territoire de kabare de la province du Sud-Kivu à savoir Bugorhe et Irhambi-katana dont le centre de kavumu a été retenu dans l’échantillonnage pour le premier et le centre Katana dans le second. Deux grandes catégories des ont intéressées la présente étude : les ménages qui exercent l’activité agricole uniquement et les ménages combinant l’activité agricole et le commerce (notés ici ménages agricommerçants). A partir des données de l’enquête menée en mars et avril 2012, nous examinons l’effet du revenu non-agricole sur la pauvreté et l’inégalité en zone rurale de la province du Sud-kivu. Nous partons d’une approche qui considère le revenu non-agricole comme un « transfert exogène » qui s’ajoute au revenu total du ménage et analysons la contribution des différents types de revenus à l’inégalité en utilisant la décomposition de l’indice de Gini. Nous analysons la pauvreté en référence à l’approche de la Banque Africaine de Développement (2010) de l’analyse de la pauvreté en RDC. L’approche absolue de mesure de la pauvreté (pauvreté monétaire) qui est mesurée par les indices de Foster-Greer Thorbecke (F.G.T, 1984). L’étude a porté sur un échantillon de 135 ménages obtenu à partir de la technique de sondage systématique appliquée sur les ménages agri-commerçants, et d’un échantillonnage par quotas appliqué sur les ménages à unique activité agricole. Selon ces enquêtes, les ménages agricommerçants échappent aux chocs négatifs grâce à l’activité commerciale qui assure les besoins de base et finance l’activité agricole. Malgré le déclin relatif et structurel du secteur agricole du Sud-Kivu, 98,3% des ménages n’abandonnent pas cette activité pour des raisons d’autoconsommation (100% des ménages), de sécurité et d’estime sociale (73%), de stabilité économique (82%). Les ménages à unique activité agricole sont plus exposés au phénomène de pauvreté : 80,9% d’eux vivent avec un revenu inférieur au seuil minimum de 171,2$/pers/an. La profondeur de la pauvreté est plus accentuée chez les ménages agriculteurs (37,6%) que chez les ménages agri-commerçants (1,9%). En plus, la pauvreté est plus sévère chez les ménages agriculteurs (21,9%) que chez les ménages agri-commerçants (0,3%). Le secteur agricole contribue moins à l’inégalité par rapport à l’activité de commerce. En effet, pour un indice de Gini de 0,5242, le revenu issu du commerce contribue fortement à l’inégalité de revenus des ménages à l’ordre de 58,7% contre une contribution à l’inégalité de l’ordre de 24,4% du revenu agricole pour un indice de Gini de 0,2356. Dans le contexte du milieu d’étude, l’activité commerciale permet aux ménages de survivre mais n’est pas un moyen efficace pour un développement rural durable dans ce milieu à fort potentialité agricole.

This paper offers an examination of three significant familial inscriptions from the Hellenistic period. The texts are detailed cultic dossiers initiated by three individuals—Diomedon on Cos, Poseidonios in Halicarnassus, and Epikteta on Thera. Though they are often very briefly grouped together, these inscriptions are discussed here in greater textual and contextual detail. In particular, the analysis focusses on the cult personnel, which is appointed in these families, demonstrating that it remains independent from the polis, but is organised with reference to a civic framework. By setting these inscriptions in parallel, the discussion opens up productive perspectives on the evolutions of familial cults in the Hellenistic period.—The inscription of Poseidonios is reedited in an Appendix by Jan-Mathieu Carbon.

Burundi, family agriculture occupies more than 90% of the active population and plays a vital role in food production and participates of more than 50% of GDP. Before the civil war of 1993, Kirundo was deemed "breadbasket of the country" for the simple reason that fed many parts of Burundi in particular food legumes and cereals, so that family farming was oriented the market. Kirundo alone includes 8 lakes with opportunities for field irrigation. Today, this is the first province in Burundi shows a high rate of malnutrition, poverty increased and a sharp decline in agricultural production up more than 500%. In this study, 73 farmers were surveyed in Kirundo, supplemented by secondary data collection. Analysis of data showed us that, despite recurrent droughts in that region which was caused several deaths due to famines and several displacements of people to neighboring countries such as Rwanda and Tanzania, we found 44% of farmers surveyed who had the resilience to climate change. The analysis of data shows that these farmers were members of local development associations, having learned specific topics such as financial management, processing and storage of agricultural products and livestock. That social capital network influences positively their income because they practice not only farming but also revenue-generating activities such as trade and crafts. [less ▲]

Ce travail s'inscrit dans un cadre géographique regroupant deux pays (RDC et Rwanda) appartenant à la Communauté Économique des Pays des Grands Lacs (CEPGL) avec le Burundi. Le commerce des produits alimentaires entre population transfrontalière est une réalité: Elle est facilitée par un ensemble d'accords et certaines pratiques de proximité qui n'ont jamais été mises en cause, même pendant les périodes des guerres. Les flux importants de produits alimentaires enregistrés lors de la traversée du corridor frontalier entre Bukavu (RDC) et le district de Rusizi (Rwanda), les difficultés et risques auxquels les petits commerçants et les ménages sont soumis, constituent des éléments qui ont guidé le choix de l'approche conceptuelle. Lors de la traversée des frontières, on peut se rendre compte que la ville de Bukavu et le district de Rusizi (Rwanda) ont des fonctions bien réparties. Alors que Bukavu fonctionne comme un grand centre de consommation, le district de Rusizi s'est positionné stratégiquement comme une ville entrepôt (Soule et Musila, 2005). Ces approvisionnements à partir de l'étranger solidifient encore la dépendance alimentaire de la province du Sud-Kivu en général et la ville de Bukavu en particulier. Ce problème mérite une étude particulière et a guidé aussi le choix de ce travail. Le choix de l'approche conceptuelle de cette étude a été aussi motivé par le souci d'étalonner la contribution du commerce frontalier à la paix, à la lutte contre la pauvreté et à la sécurité alimentaire. Ceci constitue des réponses à plusieurs préoccupations de développement et d'intégration régionale. Dans ce cadre, plusieurs auteurs, comme Johnson et al. (2009), Cling (2006), Tegera et al. (2007), Masato Hayashikawa (2009), ont déjà montré qu'il existe un lien entre commerce, développement et lutte contre la pauvreté. Divers programmes sous-régionaux (CEPGL), régionaux (COMESA, CIRGL), internationaux (Banque mondiale) ainsi que diverses ONGs internationales (Alert International, DFID) s'intéressent à cette problématique.

Dans le cadre de la conception d’un expanseur dédié à la récupération d’énergie à l’échappement d’un moteur à combustion interne, une étude sur des lubrifiants solides a été menée afin de choisir le couple de matériaux adéquat pour le joint principal de la machine. Ce joint doit assurer à la fois une fonction d’étanchéité interne et limiter ainsi les pertes par fuites internes de l’expanseur. Il doit également présenter un coefficient de frottement la plus faible possible afin de réduire les pertes par friction. Ce joint est en effet sollicité par des contraintes en frottement plan dans un environnement sous vapeur d’eau à des températures pouvant atteindre 250°C. Ces températures rendent complexe l’utilisation d’huile et le recours à des matériaux auto lubrifiants est dès lors l’unique solution. [less ▲]

X-ray tomography is used to investigate the influence of packing geometry and of liquid viscosity on hydrodynamic quantities, as well as on the liquid flow morphology inside a packed column successively filled with two structured metallic packing, M752Y and M500X. As expected, liquid holdup and gas-liquid interfacial area increase with liquid flow rate and viscosity. In both packings, the film flow pattern predominates, while flooded regions remain minority. The influence of liquid flow rate and viscosity on flow morphology depends on the packing geometry. In M752Y, film and flooded region flows are clearly influenced, whereas in M500X, they are not.

This contribution discusses a coupled two-scale framework for hydro-mechanical problems in saturated heterogeneous porous geomaterials. The heterogeneous nature of such materials can lead to an anisotropy of the hydro-mechanical couplings and non-linear effects. Based on an assumed model of the mesostructure, the average macroscopic hydro-mechanical behaviour is extracted by means of a computational homogenisation procedure in a monolithic way. The ingredients needed to upscale the hydro-mechanical couplings are outlined. The two-scale simulation results are compared with direct numerical simulation for the consolidation of a particle-matrix porous material. [less ▲]

Detailed inundation modelling was conducted along a 100 km long transnational section of the Meuse River (in Belgium and The Netherlands), using very similar models for the whole computation (2D unsteady models). As a result, damping of the flood waves could be quantified and the possible relevance of using a steady-state approach could be assessed. The new detailed 2D hydraulic simulations have demonstrated that only a very limited damping of the flood waves occurs along the simulated reaches. From the perspective of the variation in peak discharge, the study concludes that running the hydraulic model in steady mode makes perfectly sense. Nonetheless, the steady computations lead to extensive overestimations of the inundated extent and of the stored volume in the floodplains. The 2D unsteady model constitutes also a tool of primary interest, which is readily available to design and evaluate protection measures for flood-prone areas such as in the city of Liege. [less ▲]

This paper investigates the transition of the Flemish travel survey (OVG) from a household-based travel survey to a person-based travel survey. The paper examines the design features of the different OVGs, with particular attention to the resulting response rates. In addition to the sample unit, the contact and survey procedure has switched from telephone/postal to face-to-face. The most striking effect of the changed methodology is the spectacular increase in the response rates: overall response rates of the most recent OVGs were more than double that of the previous OVGs, resulting in overall response rates of 75%. In addition, the likelihood that some questionnaires were missing (e.g. diaries were retrieved, but household questionnaires were not) decreased from 7% to 3%. Furthermore, the paper shows that a person-based travel survey still can be used for travel demand modeling frameworks that incorporate (some) household interactions. Notwithstanding, some issues have been raised, such as the decreased comparability of travel figures due to the changes in the survey design. In conclusion, the inclusion of a “with whom” dimension in the trip diary is recommended, and it is advocated that policy makers should clearly outline the primary objectives for the OVG for the coming years.

In Belgium, Palaeolithic research goes back to the early 19th century, in the wake of mining and quarry work. Geology and paleontology developed early and rapidly and were economically important. As a result, the earliest human history was reconstructed here entirely independently, by defining the Mousterian (Engis, 1830), Aurignacian (Montaigle), Gravettian (Trou Magrite) and Magdalenian (Chaleux) periods. Belgium, due to its central position, is in addition particularly representative of the wave of "modernity" that suddenly was adopted across northwest Europe, overlying a highly diverse and innovative cultural base during the time of the Neandertals. At this point in time, as in others, Belgium played the role of intermediary and incubator between the British Isles and the Rhineland, extending as far as the Loire. [less ▲]

This paper presents the results of an experimental campaign performed to assess the effect of the flame emissivity for steel members engulfed into fire. In detail, two sizes of circular steel tubes were engulfed into pool fires of two different diameters. Two fuels were used and for both fuels tests without column (used as comparison with existing localised fire models) and with column were performed. The temperature of the column and of the flames were measured at different heights. The width of the flame was also measured and used to calculate the emissivity of the flame the value of which was employed in numerical simulations in order to predict the evolution of the temperature of the steel column. Comparison with numerical analyses where the recommended values of the Eurocode were used is also shown. [less ▲]

Assessment of the overall seismic performances of multi-storey unreinforced masonry structures requires an appropriate characterization of the behaviour of their structural components, in particular when these are subjected to a dynamic ground motion input. In order to develop a better understanding on this issue and in a further perspective of investigating the consequences of the presence of 1 cm thick rubber elements used for improving the sound-proofing performances of the building, shaking table tests have been carried out in the framework of the European project SERIES. Four single walls were tested. These were built with high resistance thin-bed layered clay masonry with empty vertical joints. Two of them had an aspect ratio close to 1, while the other two were close to 0.4. One wall of each aspect ratio included rubber devices at its bottom and top to enable comparisons and conclusions about the influence of rubber on the wall behaviour. The test results were then partially compared to results obtained with a theoretical rocking model considering the wall as a rigid body. The results summarized in the present contribution evidence a significant rocking behaviour for the highest input acceleration levels. Characterization of this behaviour is however strongly dependent on the aspect ratio of the wall and on the presence or not of rubber devices in terms of natural frequencies, damping, dynamic amplifications and progressive damage with increasing acceleration levels. It is also showed that the theoretical rocking predictions are in good agreement with the experimental results for high acceleration levels, while the behaviour is closer to the one of a cantilever for the lower levels. It is finally evidenced that, in presence of acoustic rubber devices, amplitudes of the rocking motion are increased but with a more limited damaging of the wall because of the capacity of the rubber to absorb the impact energy. Results of this study on single walls are expected to be further extended to global masonry structures, account taken for the influence of actual boundary conditions of the wall. [less ▲]

Organic farming is today fully recognized as an alternative to conventional agriculture and its problems (water and air pollution, large use of pesticides and possible impacts on human health, vegetal and animal diseases, overproduction, ..) and is clearly supported by the Common Agricultural Policy and its "greening". Belgian (and Walloon) agriculture is an intensive one, with a high "labour force/agricultural area" ratio and high yields thanks to good soils, but also the use of large quantities of inputs like fertilizers and pesticides. However, organic farming increased in importance during the last years and th Walloon regional government has just launched a development plan in June 2013. So, this paper aims to analyse the evolution of organic farming in Wallonia and to present the goals and the measures of the new development plan. [less ▲]

In this paper, we study the origins of the northern Congo Republic rainforests. Macroscopic charcoal fragments were systematically recorded through auger investigations and pits observations in four forest types: the open canopy Marantaceae forest, the dense forest with Marantaceae, the Gilbertiodendron dewevrei forest and the Triplochiton scleroxylon forest. In addition, the charred Elaies guineensis seeds were distinguished from the other charcoals in the pits. Ten selected charcoals, including charred E. guineensis seeds, were dated by AMS. Abundance of charcoal fragments in the soils at various depths indicated several episodes of fires in the region. A dryer climatic phase, between 2320 and 1330 BP, associated with a large scale human occupation related to the important harvesting of oil palm nuts, could explain the widespread Marantaceae forests. Recent slash-and-burn shifting cultivation, c. 200 BP, would allow T. scleroxylon installation. Implications for forest management are discussed. [less ▲]

The recently developed SSH3D solid-shell element, which is based on the Enhanced Assumed Strain (EAS) and the Assumed Natural Strain (ANS) techniques, is utilized for the modeling of a severe bending sheet forming process. To improve the element's ability to capture the through thickness gradients, a specific integration scheme was developed. In this paper, the performances of this element for the modeling of the T-bent process were assessed thanks to comparison between experimental and numerical results in terms of the strain field at the outer surface of the sheet. The experimental results were obtained by Digital Image Correlation. It is shown that a qualitative agreement between experimental and numerical results is obtained but some numerical parameters should be optimized to improve the accuracy of the simulation predictions. In this respect, the influence of the penalty coefficient of the contact modeling was analyzed. [less ▲]
