En matière d’architecture conventuelle féminine post-tridentine, les directives des autorités ecclésiastiques (cf. Carlo Borromeo) se focalisent presque exclusivement sur les infrastructures de la clôture qui revêt une charge spirituelle et symbolique importante. Les annonciades célestes sont particulièrement représentatives des congrégations féminines apparues dans le contexte de la Réforme catholique. Strictement cloîtrées tout en étant implantées au coeur des villes, ces religieuses apparaissent comme particulièrement observantes des normes édictées par les théoriciens de la clôture. Pourtant, ces religieuses rigoureusement cloîtrées sont amenées à sortir de leurs murs, notamment pour fonder de nouvelles communautés ou fuir un conflit armé. Il est alors intéressant d’exploiter les sources architecturales pour comprendre comment elles parviennent à maintenir l’observance de la clôture, à la déplacer virtuellement et à mettre en place les dispositifs d’une clôture provisoire lors d’une installation temporaire hors du cloître ou portative, à l’occasion d’un voyage. Outre ces pratiques qu’ils documentent, les textes produits par les annonciades permettent aussi d’accéder à leurs représentations mentales de la clôture qui révèlent leur conception des entrées et sorties du cloître. Parallèlement, l’iconographie attachée à cet ordre, en particulier les images de leur fondatrice Vittoria Fornari (1562-1617), apportera un complément très intéressant pour comprendre le dialogue relationnel entre l’extérieur et l’intérieur, entretenu dans l’imaginaire de ces religieuses. En regard de ces pratiques de parfaite observance de la règle, il est également pertinent d’interroger les sources d’autres congrégations féminines post-tridentines qui pourraient avoir pris plus de latitude vis-à-vis des normes.

The Mantile door and the Capitol dorr of the Tournai Cathedral, a monument listed as a Word Heritage Site, are among the most intersting of Belgium. Their trilobal shape seems relatively exceptional and gives them teheir character. The sculptures on these portals from the 12th century have not revealed all their secrets, particularly with regard to their place in the global iconographic programme of the Cathedral. A preliminary study initiated in 2012 to better undestand their structure is part of the vast project on conservation of the Cathedral oranized an international meeting with the scientific collaboration of the IRPA. This Conference was to be an opportunity to update and deepen our knowledge of church portals in their widest aspects - technical, typological, stylistic, iconographic - both in terms of architecture and sculpture. Comparisons with contemporary portals, in France in particular, was alson ath the heart of the discussions. [less ▲]

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

The 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 ▲]

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 ▲]

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 ▲]

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.

There is a growing interest in uncertainty handling in the spacecraft dynamics community. In particular, robust optimization of spacecraft maneuvers is regarded as an important challenge. This paper proposes an optimal control approach for orbital rendez-vous planning under stochastic dynamics and constraints. The method combines differential flatness theory with the scenario approach for optimization under uncertainties. By mapping state and control variables into a set of flat outputs, the enforcement of dynamics equations and boundary conditions is automatically satisfied. The rigorous foundations of the scenario approach lead to a finite-dimensional formulation of the problem which guarantees the feasibility of the solution within an arbitrary portion of the stochastic domain. The methodology is illustrated by means of two case studies involving a rendez-vous in elliptic orbit and a propellantless maneuver using differential drag, respectively. [less ▲]

This paper presents a method to model heat exchangers used in waste heat recovery Rankine based systems in heavy duty trucks. The method is developed to predict both transfer and working fluid physical properties such as temperature and density after the heat exchange process. Due to the flexibility of such a model, it can be used for a numerous quantity of fluids including water-alcohol mixture. A validation of the developed model is shown and compared to steady state and dynamic test results. The model shows good performance as well in terms of accuracy, which is in the range of 5K error as in computational time which is faster than real time and makes it suitable for concept optimization, control and fuel economy evaluation.

Les origines savantes ou populaires des épopées françaises médiévales ont longtemps fait débat. Il s'avère que ces textes contiennent un très grand nombre de références à des personnages issus de l’Antiquité qui témoignent d’une formation scolaire chez les auteurs des chansons. Sur la base d'un examen de l'ensemble du corpus, cette étude s'intéresse plus particulièrement aux mentions explicites faites à des auteurs antiques, qu'ils soient grecs (Homère, Aristote, Platon) ou latins (Virgile, Ovide, César, Caton, Sénèque).

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 ▲]

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 ▲]

The wear characteristics of three high speed steel grades were studied, one of them being obtained from a conventional casting process and two others originated from a laser cladding route. Tribological tests were carried out at room temperature using a “pin-on-disc” device. The setting of the wear test parameters together with the microstructure of the studied materials seems to strongly influence the subsequent abrasion and wear mechanisms. The results show that the laser cladded high speed steel materials resist better to wear thanks to their ultrafine microstructure compared to the conventional cast material. [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 ▲]

This research analyzes the gender dimensions of labor migration and agricultural production among farm households in Red River Delta region of Vietnam. Through surveying 215 households in Bac Ninh province, the paper explores impacts of female and male migration on agricultural production and its implications on rural development. The results show that in comparison to male migration household, the female one tends to focus on agricultural production by taking the opportunities to rent more land (26.3%) and effective use their own allocated land for agricultural production (97.4%). The overall impacts of migration on agricultural production are the aging of farm labor force (49.6 year old in average) and higher female participation in agricultural production. The findings suggest that female migrants have a greater contribution in agriculture production both in term of working time and agricultural capital investment while male migrants enhance household income by accumulating capital outside agriculture. Through the gender lens, this research emphasizes the duality in the nature of migrant lives and the implications of rural labor migration on the fixed categories. [less ▲]

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

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

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

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 ▲]

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 ▲]

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 ▲]

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 ▲]

Les aspects "santé" prenant de plus en plus d'importance dans les pays riches, la bonne réputation de l'épeautre en ce domaine a permis un récent regain d'intérêt pour cette culture, dont les prix se sont envolés au cours de l'année 2014.

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 ▲]

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.

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 ▲]

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.

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.

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.

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 ▲]

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.

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

Fiber reinforced cementitious composite (FRCC) materials have been widely used during last decades in order to overcome some of traditional cementitious materials issues: brittle behaviour, fire resistance, cover spalling, impact strength. For composite materials, fiber/matrix bond plays an important role because by increasing fiber/matrix interactions is possible to increase the behaviour of the entire material. In this study, in order to improve fiber to matrix adhesion, two chemical treatments of polypropylene fibers were investigated: alkaline hydrolysis and nano-silica sol-gel particles deposition. Treatmtents effect on fibers morphology and mechanical properties was investigated by scanning electron microscopy (SEM) and tensile tests. SEM investigations report the presence of spherical nano-silica particles on fiber surface, in the case of sol-gel process, while alkaline hydrolysis leads to an increase of fibers roughness. Both treatments have negligible influence on fibers mechanical properties confirming the possibility of their use in a cementitious mortar. Pullout tests were carried out considering three embedded length of fibers in mortar samples (10, 20 and 30 mm, respectively) showing an increase of pullout energy for treated fibers. The influence on fiber reinforced mortar mechanical properties was investigated by three-point flexural tests on prismatic specimens considering two fibers length (15 and 30 mm) and two fibers volume fractions (0.50 and 1.00 %). A general increase of flexural strength over the reference mix was achieved and an overall better behaviour is recognizable for mortars containing treated fibers. [less ▲]

Cette enquête est dédiée au "Portrait d'homme en armure", l'une des œuvres les plus célèbres du peintre Giovanni Gerolamo Savoldo. Elle se concentre sur l'identification présumée du modèle avec Gaston de Foix et sur les raisons de cette association. Elle s'attache également à l'histoire ancienne du tableau, qui peut être restituée avec précision : l’œuvre, qui provient de la collection de peintures de François Ier, a été conservée dans l'appartement des bains du château de Fontainebleau. Enfin, les intentions du premier roi Valois sont interrogées. Pourquoi et comment François Ier a-t-il acquis ce portrait et, surtout, pourquoi l'a-t-il exposé dans les salles du château qui étaient dédiées au bain ? [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 ▲]
