On analyse ici les manifestations discursives de la contradiction que constitue en soi, pour le discours médiatique, un événement, et ce en faisant porter l'interrogation sur le récepteur. Il s'agit de se demander comment le média relaie le choc que constitue l'événement en nouant ensemble deux affirmations : l'événement fait quelque chose au discours médiatique et celui-ci fait quelque chose au lecteur. Cette dimension performative du discours est soutenue par la déconstruction derridienne du signe linguistique et par la notion de "partage du sensible" de Jacques Rancière. [less ▲]

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 ▲]

La présente étude part d’un constat selon lequel; des ménages se retrouvent dans une situation d’insécurité alimentaire lorsque leurs modes de vie et moyens d’existence ne sont pas adaptés et qu’ils n’ont pas la capacité de trouver un équilibre entre un ensemble de besoins. La demande alimentaire des ménages ne peut donc être analysée indépendamment de l’ensemble des moyens d’existence et conditions de vie des ménages: relations sociales, ressources disponibles, localisation géographique. Trois quartiers de la ville de Kinshasa ont été choisis en fonction de leur niveau présumé de richesse afin d’analyser les modes de consommation alimentaire des ménages. Il s’agit du quartier Résidentiel de la commune de Limete (quartier aisé), les quartiers 1 et 7 dans la commune de Ndjili (quartier moyen) et le quartier Mabulu dans la commune de Makala (quartier pauvre). Le suivi rapproché de 30 ménages a permis de mettre en évidence les liens entre les modes de vie et les modes de consommation alimentaire. S’agissant des modes de vie, il a été identifié que pour accéder à l'alimentation, les ménages ont développé deux stratégies: la diversification des sources des revenus et la diversification des pourvoyeurs de revenus. Le nombre de sources de revenu par ménage est respectivement de 4 dans les ménages moins aisés et de 2 dans les ménages moyens et dans les ménages aisés. Ce nombre tend à augmenter avec la détérioration des conditions de vie. Le revenu hebdomadaire des membres des ménages a été estimé à respectivement 602 USD quartier aisé, 181 USD dans le quartier moyen et 41 USD dans le quartier pauvre. S’agissant des modes de consommation alimentaire, l’étude a montré que :la part des dépenses des céréales tend à diminuer dans les ménages moins aisés. Les racines et tubercules présentent une tendance opposée à celle des céréales. Ce sont les ménages les moins aisés qui consacrent la part relative la plus importante des dépenses pour l’achat des racines et tubercules soit 27% des dépenses alimentaires. Les légumineuses semblent également avoir une grande importance relative chez les ménages les moins aisés. Les ménages achètent davantage de viandes que de poissons. Les fruits sont des produits dont la consommation est saisonnière. La consommation des oeufs sous-forme d’omelette préparée hors ménage est très prisée par les ménages les moins aisés. Dans les ménages aisés, le lait est plus consommé que le sucre, la tendance est inversée pour les moins aisés. La quantité d’aliments consommés/personne/jour a été estimée respectivement à 1 120 grammes dans les ménages aisés, 801 grammes dans les ménages moyens et 493 grammes dans les ménages moins aisés. Les apports énergétiques/personne/jour sont respectivement estimés à 2452 calories dans les ménages aisés, 1838 calories dans les ménages moyens et 1130 calories dans les ménages pauvres. Les apports protéiques/personnes/jour sont respectivement dans l’ordre de 100grammes dans les ménages aisés, 80grammes dans les ménages moyens et 50grammes dans les ménages pauvres. La consommation de protéine ne semble pas être largement déficitaire tant dans les ménages aisés que dans les ménages pauvres. [less ▲]

The Eurocodes recognise robustness as a way to ensure the structural integrity of a building frame subjected to an unforeseen event and therefore to avoid a so-called “progressive failure” mode in extreme loading situations. However few practical guidelines exist nowadays which would allow a designer to design a structure accordingly. Within the European RFCS ROBUSTFIRE project, the behaviour of steel and composite car parks subjected to localised fire leading to a column loss was investigated. Under such a scenario, the beam-to-column joints play a key role in the global structural response. Indeed, these joints, initially loaded in bending, may be subjected to elevated temperatures and to combined axial load “N” and bending moment “M”. In this paper, a methodology to predict the mechanical response of bolted composite beam-to-column joints at elevated temperatures under M-N is presented and validated through comparison to experimental tests conducted at the University of Coimbra.

In the past years, mass univariate statistical analyses of neuroimaging data have been complemented by the use of multivariate pattern analyses, especially based on machine learning models. While these allow an increased sensitivity for the detection of spatially distributed e ffects compared to univariate techniques, they lack an established and accessible software framework. Here we introduce the \Pattern Recognition for Neuroimaging Toolbox" (PRoNTo), an open-source, cross-platform and MATLAB-based software comprising many necessary functionalities for machine learning modelling of neuroimaging data.

Les traités d’architecture français reflètent parfaitement l’intérêt plus ou moins appuyé pour les marbres tout au long de l’Ancien Régime. De Philibert de l’Orme à Nicolas Le Camus de Mézières, nous ferons un rapide tour d’horizon du discours sur les marbres ; discours dans lequel apparaissent des questions de provenance, de couleurs, de mise en œuvre... mais également d’usage. Nous envisagerons ainsi les emplois particuliers des marbres. En effet, dans la théorie architecturale, le choix des matériaux — que la matière soit réelle ou imitée — doit répondre à des principes bien établis, autour des notions de convenance et de bienséance. Le matériau choisi et sa mise en œuvre doivent ainsi correspondre à la fois à la qualité sociale du commanditaire et à l’usage du lieu dans lequel le matériau prend place. L’emploi des marbres nous rappelle encore la dimension « totale » de cette architecture de l’Ancien Régime, pensée et écrite avec soin, dans laquelle tous les éléments œuvrent de concert. [less ▲]

Linear modal analysis is a mature tool enjoying various applications ranging from bridges to satellites. Nevertheless, modal analysis fails in the presence of nonlinear dynamical phenomena and the development of a practical nonlinear analog of modal analysis is a current research topic. Recently, numerical techniques (e.g., harmonic balance, continuation of periodic solutions) were developed for the computation of nonlinear normal modes (NNMs). Because these methods are limited to conservative systems, the present study targets the computation of NNMs for nonconservative systems. Their definition as invariant manifolds in phase space is considered. Specifically, a new finite element technique is proposed to solve the set of partial differential equations governing the manifold geometry. [less ▲]

This paper presents a study regarding the determinants of travellers’ mental knowledge of public parking facilities. The data regarding the mental knowledge were collected in the city of Hasselt, Belgium, by means of an internet-based questionnaire. In total 1007 respondents completed the questionnaire. Two different dependent variables were specified: the mental representation of parking facilities (known or not) and the identification of parking facilities (identified first or not). In addition, three different groups of determinants were included in the models: parking attributes, personal characteristics, and mental knowledge of the city. The data are analyzed using generalized estimating equations (GEE) models for binary data. The analyses show a considerable influence of the following parking attributes: type of parking facility, Park & Ride status, charged parking, number of places, and location of parking facility. Furthermore our study revealed that personal characteristics and mental knowledge of the city play a marginal role. [less ▲]

Piano Key Weirs, a recent innovation in the Labyrinth Weirs geometry, have been studied for years by several research centers and laboratories all over the world. The first prototypes have already been built, mainly in France, and others are under construction in Vietnam, Algeria and India. Despite some general design equations have been proposed recently, no optimum geometry has been defined yet. Whatever its geometry, a PKW is more efficient than a standard linear weir of same width. It is also more efficient than a labyrinth weir with the same cycle shape. But the PKW geometry may appear as complex as it involves a large set of parameters. Optimization of the weir design is thus not straightforward. Using the results of a large number of systematic scale model tests carried out to analyse the effect of the main geometric parameters on the PKW discharge capacity, the paper shows how a single optimum design doesn’t exist. This is especially true when economic and technical criteria are considered instead of a single hydraulic performance criteria. Despite this observation, some general rules to design a PKW can be suggested, as well as considerations about the best value of the main ratios defining the structure geometry. The relative influence of these parameters on the PKW efficiency is also highlighted. [less ▲]

A hydraulic design equation for Piano Key Weirs is set up using the results of a large experimental parametric study. Comparison of the analytical formulation with experi-mental data from various physical modeling studies, considering idealized as well as real projects Piano Key Weirs configurations, shows a 15% accuracy in unit discharge prediction on a large range of geometric parameters values. Comparison of the proposed formulation to two other recently proposed equations highlights the importance to consider such analytical approaches inside the range of parameter values for which they have been validated.

L’environnement intellectuel des stratèges belges présenté dans cet article ne doit donc pas être considéré comme un corpus doctrinal précis mais plutôt comme une série d’interrogations géopolitiques propres à l’espace belge, son statut de neutralité et ses fortifications. Ainsi, les choix posés par le Roi Albert I depuis l’ordre de mobilisation le 31 juillet 1914 jusqu’au repli de l’armée belge sur Anvers dans la nuit du 18-19 août peuvent être mis en parallèle avec les divers débats, polémiques ou études stratégiques antérieurs concernant la défense de la Belgique. Au cours de ces trois premières semaines de conflit, le souverain belge est en effet confronté à trois dilemmes majeurs : 1)Quand mobiliser ? Faut-il mobiliser avant la France et l’Allemagne ? 2) Quelle attitude adopter après la phase de mobilisation ? Faut-il concentrer les troupes vers la frontière menacée ou au centre du pays ? 3) En cas d’invasion, la jonction de l’armée belge avec une armée de secours est-elle prioritaire ? [less ▲]

The Taoussa Project is a component of a large development scheme of the Niger River in the north-eastern part of Mali aiming at reducing desertification and improving socio-economic activity. It is mainly made of a rockfill dam with central core around 18 m high and 1,000 m long across the valley of the Niger River, 130 km upstream of the town of Gao in the eastern part of Mali. The dam is equipped with a 25 MW hydroelectric power plant, a lock, a dock and a spillway. The spillway is made of a gated ogee crested weir divided into 10 bays and a downstream stilling basin, with a maximum discharge capacity of 3,100 m³/s. 210 km of high tension overhead cables and a 130 km long road complete the Project. The multipurpose Taoussa dam will enable the sustainable development of the Project area by securing water resources, increasing low-water level discharges downstream, creating a link between road and fluvial transports (dock) and producing electricity. The Ministère de l’Energie, des Mines et de l’Eau du Mali - Autorité pour l’Aménagement de Taoussa -commissioned Coyne et Bellier – Tractebel Engineering in 2006 to perform the detailed studies for the Project. In this framework, the hydraulic studies have been performed by the Laboratory of Engineering Hydraulics (HECE) of the University of Liege. These hydraulic studies, depicted in details in the paper, have been carried out successively by two complementary approaches: a first step realized on the basis of numerical modelling to study the flows at the scale of the reservoir and the river, and a second experimental investigation, using a scale model, to analyse in details the spillway operation conditions. They consider varied problems from large scale flow conditions in the reservoir during the spillway operation and hydrodynamic interactions between the dam, the lock and the hydroelectric power plant to validation and optimization of the hydraulic design and dimensions of the gated spillway and the stilling basin or release conditions downstream of the project structures, including the temporary derivation stage.

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.

Gegenwärtig entwickelt die RWTH Aachen University im Rahmen des Projekts "Galileo above" (Anwendungszentrum für bodengebundenen Verkehr ) ein Kollisionsvermeidungssystem (Collision Avoidance System, CAS) unter Einbeziehung von Galileo-Daten. Ziel des CAS ist - wie der Name suggeriert - Fahrzeuge zu erkennen, die sich auf Kollisionskurs mit dem eigenen Fahrzeug befinden und automatisch eine kollisionsvermeidende Maßnahme (Bremsen und/oder Lenken) einzuleiten, insofern der Fahrer nicht rechtzeitig reagiert. Der begrenzte Erfassungsbereich und die Einschränkungen, der die verwendete kosten-optimierte Sensorik unter unterschiedlichsten Umgebungsbedingungen unterliegt, sind häufig ein begrenzender Faktor für die Realisierbarkeit und Robustheit von Fahrerassistenzsystemen (FAS). Der Einsatz von GNSS (Global Navigation Satellite System) in Verbindung mit einer digitalen Karte und Fahrzeug-zu-Fahrzeug- bzw. Fahzeug-zu-Infrastruktur-Kommunikation bietet das Potenzial, den Erfassungsbereich der Sensorik deutlich zu erweitern und diese unter schwierigen Umgebungsbedingungen zu stützen. Für die Entwicklung des CAS wird das Galileo Testzentrum automotiveGATE in Al-denhoven genutzt. Das automotiveGATE erweitert das Aldenhoven Testing Center um sogenannte Pseudoliten (Pseudo-Satelliten), welche Galileo-ähnliche Navigati-onsdaten in einem begrenzten Gebiet ausstrahlen. Das automotiveGATE ermöglicht somit die Entwicklung und Erprobung von Galileo-basierten Applikationen vor der Inbetriebnahme des eigentlichen Galileo-Satellitennavigationssystems. Im Rahmen dieses Beitrags werden Erläuterungen zur Perzeption und Sensorfusion, zur Deeskalationsstrategie und Eingriffsentscheidung sowie zu Testergebnissen bei Auffahrsituationen des CAS gegeben.

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 objective of the paper is to assess the accuracy of current Direct Strength Method (DSM) equations applied to steel structural welded H shapes in axial compression. Commercialised hot-rolled H sections covering IPE, HE, HD, HL, HP, W and UB profiles and made of three grades (235MPa, 355MPa and 460MPa) were treated in (Li & Rossi 2012). This analysis focuses on welded sections made of the same three grades, including sections characterized by local buckling with a significant post-buckling reserve. The finite element model is described. Then, the results of a parametric analysis using the finite element model are re-ported. The codified resistances are also compared to the numerical results. For each cross-section, the recently developed analytical expressions provided in (Seif & Schafer 2010) for hot-rolled profiles are used to cal-culate the elastic cross-section local buckling stress. A comparison with CUFSM results is also reported. Then, the possibility to use the concept of DSM for the design of structural welded steel shapes is discussed. [less ▲]

This paper is a first step in applying machine learning methods typical of Automated Text Catego-rization (ATC) for Automatic Genre Identification (AGI) in Late Egyptian, a language written in either hieroglyphic or hieratic scripts that is found in documents from Ancient Egypt dating from ca. 1350-700 BCE. The study is divided into three parts. After a general intro¬duction on AGI (§1), we introduce the levels of annotation that are integrated in the Ramses corpus and can be used when performing AGI on Late Egyptian (§2). In the following section (§3) we offer a brief survey of the types of features that have been discussed in the literature on AGI, before proceeding with three case studies where we apply supervised machine learning methods — namely the naïve Bayes classifier (§4.1), the Support Vector Machine (§4.2), and the Segment and Combine approach (§4.3) — to a selection of texts in the corpus. Their respective performances are tested using lexical, part-of-speech and inflectional features. [less ▲]

The present study aimed at adapting and testing a French version of Kreutzer et al.’s metamemory interview (1975) in a group of 128 children aged of 4, 6, 9, and 12. Following Fritz et al. (2010), adjustments have been made to reduce language skill contamination as well as to increase the developmental appropriateness and sensibility of the scale. Results show the emergence of two sub-scales (“strategy knowledge” and “general memory knowledge”) on the factor analysis and reveal an excellent interrater reliability as well as a good internal consistency for the global scale and two sub-scales (respectively, Cronbach α = .79; .81 and .71). As expected with regard to the literature, a significant correlation has appeared between the metamemory scale and short-term memory capacities (convergent validity). Similarly, the metamemory score has shown its ability to predict children memory performance (predictive validity). Finally, the lack of correlation between most of the scale’s items and vocabulary measurement (Peabody Picture Vocabulary Test) and the very good ability of the scale to distinguish between age groups demonstrate that the adaptations made to improve the Kreutzer et al.’s scale in terms of language’s contamination and developmental sensibility have reached their goal. Regarding its psychometric properties, these results suggest that this interview can be considered as a useful and reliable tool for developmental research. Furthermore, they confirm the importance of metamemory knowledge in memory performance. Future studies will have to be carried out to show the utility of this scale in a clinical population.

This paper describes a study of car drivers’ familiarity with the parking situation in the vicinity of a regional shopping center. The data used for this study are collected in Hasselt, a medium sized city in Belgium. The central shopping area of Hasselt is surrounded by 23 public parking facilities. 1007 residents have been asked to indicate if they are familiar with each parking facility. The concept of familiarity was related to the socio-demographic and cognitive attributes of the respondents, their trips to the city center and the type of parking facility using multinomial logistic regression and bivariate probit regression. The results show that familiarity with parking facilities is especially related to age and education, and to the frequency of car use towards the city centre, and to a lesser extent to place of residence, income and perceived mental knowledge. In addition to these results, this paper demonstrates the value of collecting virtual buffer data by means of an online survey tool. The authors recommend that simulation models that predict parking choice behavior take into account the different levels of familiarity with parking facilities, and the contributing factors. An important avenue for further research is the combination of personal and facility specific information to assess the familiarity with different types of parking facilities. [less ▲]

La mondialisation et la libéralisation économique qui s’imposent dans les pays du Sud, touchent aujourd’hui largement le secteur agricole et pose la problématique du financement de l’agriculture avec une acuité nouvelle. Les agricultures familiales ont besoin de s’intensifier, de se moderniser, de financer l’innovation technique, organisationnelle, etc. Le plus souvent, leur seule capacité d’autofinancement ne suffit pas à financer cette modernisation. Leurs besoins en services financiers portent sur diverses formes de crédit mais varie suivant les catégories d’exploitants agricoles. Le présent article s’est intéressé à analyser la dynamique du financement de la production agricole en lien avec le type d’exploitation agricole. Cet essai de typologie est fait à l’aide d’une méthode statistique basée sur l’analyse multi-variée et spécifiquement une analyse en composantes principales (ACP). Cette analyse a été appliquée à un échantillon de 475 exploitants agricoles. Les résultats montrent que les exploitants agricoles sont diversifiés et sont répartis en quatre types (pauvres et vulnérables, pauvres, riches et plus prospères) qui se distinguent par leur niveau de revenu, leur capacité d’investissement et leur accessibilité aux microcrédits. Les perceptions de l’accès aux crédits et de leur utilisation varient selon les différentes catégories d’exploitants agricoles. Dans tous les cas, il se dégage que les exploitants le plus prospère développement et adoptent des stratégies qui facilitent leur accès aux crédits et ainsi à l’investissement agricole. [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 ▲]

A l’heure où l’industrie cimentière est majoritairement responsable de la production de CO2 dans le secteur de la construction, il s’avère utile de compenser cette production par un phénomène inverse: la captation du CO2. Ce processus d’absorption de CO2, appelé carbonatation, améliore certaines propriétés du béton lors de la conversion du dioxyde de carbone CO2 en carbonate de calcium CaCO3. Les préoccupations environnementales actuelles motivent l’étude de la carbonatation dans le but de maximiser l'absorption du dioxyde de carbone. Les granulats recyclés, produits à base de déchets de béton concassés mécaniquement, peuvent prendre place dans de nouvelles applications en béton. Ils peuvent remplacer les granulats naturels en tout ou en partie, épargnant ainsi l’extraction des matières premières naturelles. La combinaison des deux approches vise à élaborer un produit dont l’impact environnemental est réduit au minimum. [less ▲]

Hypoxia Inducible Factor (HIF) has important roles in promoting pro-inflammatory and bactericidal functions in myeloid cells. Conditional genetic ablation of its major subunit Hif1alpha in the myeloid lineage consequently results in decreased inflammatory responses in classical models of acute inflammation in mice. In contrast, we observed that mice conditionally deficient for Hif1alpha in myeloid cells display enhanced sensitivity to the development of airway allergy to the experimental allergen ovalbumin as well as to house dust mite antigens. Following allergen exposure, these mice indeed developed enhanced allergen-specific T cell responses due to augmented activation of lung dendritic cells. Further analyses supported the idea that upon allergen exposure, MyD88-dependent upregulation of Hif1alpha boosts the expression of the immunosuppressive cytokine Interleukin (IL)-10 by lung interstitial macrophages. Interstitial macrophage-derived IL-10 in turn counteracts allergen-induced lung dendritic cell activation, consequently preventing the development of allergen-specific T cell responses. Thus, this study supports that, in addition to its known pro-inflammatory activities, myeloid Hif1alpha possesses immunoregulatory functions implicated in the prevention of airway allergy. [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.

In Burundi, family agriculture occupies more than 90% of the active population. That sector accounts more than 50% of GDP. Before the civil war of 1993, Kirundo province was deemed "breadbasket of the country" because the family farming was market-oriented. Today, this region is the first province in Burundi who accuses a high rate of householders who live in food insecurity. In order to conduct this study, 355 randomly selected farmers were surveyed in all municipalities of the province. This preliminary study revealed that the farmers had as major constraints: the small and land conflicts. The study case had identified 73 farmers among them who had not farmland and/ or land conflicts as constraints of agricultural productivity. Two groups emerged: 42 farmers who were not able to fully exploit their land and another group of 32 farmers with a high agricultural productivity. Results from this study show that the major problems in the first group were: lack of applying soil protection techniques, illiteracy, lack of credit which leads farmers to contract moneylenders, lack of improved seed, etc. Moreover, the main strategy used by the second group to boost their income is the practice of non-agricultural activities which influences whole production system.

Pris en tenaille entre les élections du 2 juin et la publication de la Lettre au Roi, le congrès wallon de Liège du 7 juillet 1912 reste peu connu. En termes de souvenir collectif et d’inévitable hiérarchisation des événements historiques, ce sont bien deux autres congrès wallons, tenus à Liège également, qui surnagent : le congrès « identitaire » de 1905 et le fameux congrès national d’octobre 1945. Pourtant, le congrès de 1912 a eu au moins deux implications fondamentales : entretenir, au cœur de l’été le débat sur la séparation administrative, qui rebondira après la lettre de Destrée, et acter la désignation d’un comité d’action wallonne dont les premiers noms sont proposés en séance. C’est l’origine de l’Assemblée wallonne. Notre contribution proposera d’abord un bref résumé des débats ayant animé le congrès, en montrant les nuances entre le compte rendu officiel et celui des observateurs présents.

Recent researches showed the rapid aeration of the flow downstream of piano key weirs. This could be related to the specific geometric features of the structure, creating several interacting flows and jets downstream. In order to validate this assumption, an experimental research has been carried out at the Laboratory of Engineering Hydraulics, University of Liège. The main objective of the study was to an-alyze the energy dissipation occurring in skimming flow conditions on a stepped spillway downstream of a piano key weir (PKW). Comparison with energy dissipation on a stepped spillway downstream of a standard ogee crested weir has been performed. An indirect method has been used to determine the resid-ual energy at the spillway toe. The results show that uniform flow conditions are reached faster on a stepped spillway downstream of a PWK compared to the length needed downstream of a standard ogee crested weir. Extrapolation of the results to prototype flow conditions is also discussed with regards to scale effects influence. [less ▲]

Network Intrusion Detection Systems (NIDSes) face significant challenges coming from the relentless network link speed growth and increasing complexity of threats. Both hardware accelerated and parallel software-based NIDS solutions, based on commodity multi-core and GPU processors, have been proposed to overcome these challenges. Network Intrusion Detection Systems (NIDSes) face significant challenges coming from the relentless network link speed growth and increasing complexity of threats. Both hardware accelerated and parallel software-based NIDS solutions, based on commodity multi-core and GPU processors, have been proposed to overcome these challenges. This work explores new parallel opportunities afforded by many-core processors for high performance, scalable and inexpensive NIDS. We exploit the huge many-core computational power by adopting a hybrid parallel architecture combining data and pipeline parallelism. We also design a hybrid load balancing scheme, using both ruleset and flow space partitioning. Furthermore, the proposed design leverages particular features of the processor to break the bottlenecks. We have integrated the open source NIDS Suricata into our proposed design and evaluated its performance with synthetic traffic. The prototype exhibits almost linear speedup and can handle up to 7.2 Gbps traffic with 100-bytes packets. [less ▲]

This paper reviews the experience of the Ramses Project in constructing a richly annotated corpus of Late Egyptian that consists of 300 000 words in 2011 (and is expected to grow up to more than 1 million words in coming years). During the first five years of the project, this corpus has been encoded in hieroglyphic script, translated in French or English and received annotations for part-of-speech information, lemmatization, and morphological analysis. The methodology and working tools that have been developed in order to build this corpus are here discussed and future developments are presented. [less ▲]

Middleboxes are heavily used in the Internet to process the network tra c for a speci c purpose. As there is no open standards, these proprietary boxes are expensive and di - cult to upgrade. In this paper, we present a programmable platform for middleboxes called FlowOS to run on commod- ity hardware. It provides an elegant programming model for writing ow processing software, which hides the complexi- ties of low-level packet processing, process synchronisation, and inter-process communication. We show that FlowOS itself does not add any signi cant overhead to ows by pre- senting some preliminary test results. [less ▲]

The article aims at characterizing forms and functions of the uses of Middle Kingdom art in royal and court productions during the Thutmosid Period. In order to assess this artistic phenomenon as a conscious revival and not just a survival of the Past and of the tradition, the analysis starts with a brief examination of the disruption that was felt and expressed during the Second Intermediate Period. It then goes on investigating the evolution of the references to Middle Kingdom art from the dawn of the 18th Dynasty to the time of Hatshepsut and Thutmosis III, when some sorts of artistic quotations replaced a global renaissance of Middle Kingdom forms of expression. A special attention is paid to the relationship between creativity and archaism under the reign of Hatshepsut, and leads to conclude the article with some theoretical deductions on the study of Ancient Egyptian archaism and a tentative definition of how innovation was conceptualized in Ancient Egyptian culture.

Organic farming is more and more considered as a credible alternative to conventional agriculture, being able to solve current problesm, notably with respect to environment, employment and food safety. In the South of Belgium, Wallonia, organic farming represents today a significant part of agriculture. The goal of this paper is to show the growth of organic farming in Wallonia, to examine the present situation and to analyse the public support granted to organic farming, through direct payments but also through a new regional development plan including research, extension, promotion and the definition of quantified targets concerning economic activity and consumption. The results are based on statistical data collection and on a Survey among organic cereals producers, in order to contribute to the assessment of the economic relevance of organic farming. [less ▲]

Rwanda is a landlocked country, situated in central and east Africa. It is one of the poorest countries in world, 166th in 186 classified (IDH, 2012). The poor households poverty are shown decreasing from 58.9% in 2000/01 (EICV1) to 44.9% in 2010/11 (EICV3) . At the same period, extreme poverty shows similar patterns; on national level it fell from 40% in 2000/01 to 24.1% in 2010/11. This paper analyses the contribution of the social protection programs to poverty reduction of household beneficiaries: (1) The Vision 2020 Umurenge Programme (VUP) – an Integrated Local Development Program which has trees components: (i) Direct support (DS) for the poorest people who are not able to work. (ii) Public Works (PW) – this component promote the rural employment on productive community assets development projects and (iii) Financial Services (FS) – which increase the access to financial services for the poor for providing loan at low interest rate. (2) The Girinka programme as known “one cow per one poor family”. The programme aims at enabling poor household to own and manage an improved dairy cow which would help the family to better their livelihood through increased milk and meat production and to improve soil fertility of their land for their crops using the available manure. After presenting briefly the achievements, we will compare the socio-economic conditions of genocide windows before and after launching these programs in Munyiginya Sector in Rwamagana Districts.

Sans être une revue exhaustive et détaillée de tout ce qui s’est fait et se fait en Belgique francophone en ce qui concerne la formation des enseignants, cet article propose un arrêt sur image permettant de constater ce qui est mis en place en 2013, d'en discuter et de découvrir ce qui se prévoit dans un avenir plus ou moins proche. En s'appuyant sur le discours européen sur la maîtrise des TIC par les enseignants, les auteurs pointent du doigt les différents programmes de formation accessibles aux (futurs) enseignants, que ce soit au cours de leur formation initiale ou dans un cadre de formation continué. Ils envisagent également les formations complémentaires et présentent la seule certification TIC existant à l'heure d'écrire ce texte : form@TICEF. La description qui en est faite met l'accent sur les objectifs annoncés et sur la méthodologie originale qui y est mise en place. Pour compléter le tableau, les différentes initiatives qui naissent actuellement dans le paysage belge sont évoquées, trouvant logiquement leur place parmi les perspectives de la formation en TIC des enseignants. Des constats sont tirés, des réflexions sont amenées, le débat est ouvert. [less ▲]

This paper analyses the contribution of three programs of poverty reduction in Rwanda. It uses data from different reports and surveys with beneficiary poor households of social protection programs. The activities developed by these programs have allowed the poor in general and the widows of genocide in the Eastern Province of Rwanda in particular to improve their socioeconomic conditions, notably access to education, accommodation and medical care. Moreover, the beneficiaries have developed activities that diversify households’ revenues and improve their economic resilience. [less ▲]

This study was conducted during three production cycles of the third year of vegetation. The main objective was to determine the production of dry matter (DM) and crude protein (CP) made under the influence of mixture and fertilization with nitrogen on P50 agrofond to alfalfa and orchard grass. To achieve these objectives, three variants of mixture were tested between alfalfa and cocksfoot that were applied to four rates of mineral fertilizers. The mixture 75% alfalfa (Medicago sativa L.) and 25% orchard grass (Dactylis glomerata L.) under the effect of dosing with N100P50achieved the highest production increase of DM on cycle I, 108% (5.24 Mg haDM) compared to the control, unfertilized alfalfa in pure culture (4.85 Mg ha DM). The highest increase forthe CP yield was obtained on cycle I from the 100% alfalfa fertilized with doses of N-1-1100P50, 122% (1230 kg haCP) from 100% alfalfa unfertilized (1009 kg ha CP). Alfalfa fertilized with N-1-1100P50 rate had the highest increases on total DM yield (106%, 10.64 Mg haDM) and on total quantity of CP(124%, 2304 kg ha CP). [less ▲]
