[more ▼] China is becoming a major actor in Latin America. Trade between Latin America and China has strongly increased the last decade, Chinese investments in Latin America are soaring, and there are increasing political, cultural and military exchanges. Lately questions have been posed about the impact of China’s involvement on Latin America’s development strategies as well as future political and security implications. What implications does the relationship with China have for the economic development of Latin America? How will it affect the relationship to the United States, the European Union, and other major powers?

[more ▼] DNA methylation and histone deacetylation are two key epigenetic modifications that play central role in regulation of gene expression. Several studies have shown that histone deacetylases (HDAC) and DNA methyltransferases (DNMT) inhibitors are potent anti-angiogenic compounds. Though combination of HDAC and DNMT inhibitors are now being examined in clinical trials of hematological malignancies, little work has been done to understand the effect of this combination on physiological and tumoral angiogenesis. We have designed and tested a family of twin drugs with intrinsic HDAC and DNMT inhibitory activities in relevant models of angiogenesis in vitro (Human Umbilical Vein Endothelial Cells – HUVEC and aortic ring) and in vivo (chick chorioallantoic membrane and Zebrafish). We have identified a lead compound having quantifiable anti-angiogenic effect without cytotoxicity affecting global histone acetylation and DNA methylation levels. In order to elucidate its anti-angiogenic mechanism, we characterized gene expression pattern simultaneously with the methylation profile of HUVEC cells treated with the lead compound and reference epigenetic modulators. This approach based on parallel microarray analyses permitted us to underscore a list of genes exclusively affected by the lead compound but not by other HDAC or DNMT inhibitors. These genes were then analyzed using the Ingenuity Pathway software revealing potential involvement of a subset of genes in angiogenesis. Our present work is focused on exploring the exact role of these genes on angiogenesis using RNA silencing and vectors cloned with genes of interest. We are using these novel epigenetic modulators as a tool to understand the regulatory mechanism of angiogenesis and to develop effective approaches to treat cancer.

Exploiting the growing ... [more ▼] The Precise Point Positioning (PPP) has become a powerful satellite positioning technique which nearly equals performances provided by advanced relative positioning techniques. Exploiting the growing availability and quality of IGS products (satellite orbit and clock products), the PPP technique can now provide a centimetre level solution in static mode and a decimetre level in kinematic mode. However, the PPP technique still presents some weaknesses. In order to reach a high precision level, it requires a significant convergence period which can typically reach 30 minutes under normal conditions. Moreover, the PPP seems to be especially sensitive to ionospheric scintillations effects which involve signal amplitude and phase variations of GNSS signals. These weaknesses still limit the use of the PPP technique in the frame of some specific and demanding applications (agricultural industry, airborne mapping, etc.). The goal of our research project is to develop new data processing strategies attempting both to make the PPP technique more reliable under ionospheric scintillations and to optimize the PPP convergence time. The project is composed of several workpackages aiming to improve the mentioned current PPP weaknesses with specific strategies. One of the workpackages is devoted to the impact of satellite geometry on PPP performances. Ionospheric scintillations are susceptible to reduce the number of tracked satellites which degrades the quality of satellite geometry. Based on an analytical development, we first attempt to figure out what types of satellite geometry can be harmful. Then, we discuss about the improvement of the satellite geometry quality involved by the combined use of GPS and Galileo and its benefits in the frame of the PPP. Another workpackage is related to the weighting scheme. Based on an iterative least-square adjustment, the PPP algorithm requires the definition of a stochastic model composed of an observation covariance matrix. Usually, this matrix is chosen as diagonal with zero covariances assuming that correlations between observations can be neglected. In particular, our project aims to study the validity of this stochastic model for the PPP in order to determine whether tuning the weighting scheme of the stochastic model can improve the PPP performances. By exploiting spatial analysis techniques, we try to characterize the spatial auto-correlation between GNSS observations, considering the signal-to-noise ratio as the main observable. From the results of these experiments, we will discuss about the spatial correlation between GNSS observations both under normal conditions and ionospheric scintillations.

La gestion de ces établissements fréquemment secoués par des « imprévus » (émeutes, grèves, évasions, détérioration des bâtiments) repose sur des acteurs spécifiques : les directeurs de prison. Bien que peu étudiés, ils se situent au centre de l’institution pénitentiaire, véritables interfaces entre les discours et politiques étatiques et les pratiques locales. L’objectif de cet article consiste à décrire et analyser travail concret afin de saisir les spécificités d’un métier méconnu qui se joue en équipe (les staffs de direction) et d’analyser les chantiers de « modernisation » essentiellement (juridique et managériale) de l’administration pénitentiaire belge.

[more ▼] Imagerie par ombroscopie avec LEDs pulsées L’imagerie par ombroscopie est une technique adaptée à la visualisation des gouttes, particules, bulles,.. Cette méthode se base sur une imagerie de haute résolution et un éclairage de fond pulsé. Dans une variante de la méthode, la lumière est émise au moyen de sources LEDs de haute puissance focalisées par des optiques en vue d'obtenir une haute illumination de la scène. Le plan focal et la profondeur de champ des composants de l’optique définissent le volume de mesure en combinaison avec le filtrage de l'image réalisé en post-traitement. Ce post-traitement s'impose pour régler les problèmes d'uniformité de l'arrière plan provenant tant des différences entre LEDs que des particules non focalisées ainsi que de différences d’atténuation en fonction de la taille des particules. La source lumineuse est une lampe composée de LEDs pulsées à un intervalle fonction de la vitesse des particules. En utilisant une impulsion courte pour l’éclairage et un overdrive du courant nominal des LEDs, il est possible de figer le mouvement jusqu’à des vitesses élevées par des temps d'exposition de quelques microsecondes. Un contrôleur à deux voies permet de réaliser une double impulsion, ce qui combiné à une caméra double exposition permet la détermination des vitesses de particules en fonction de leur taille. Des travaux sur la mesure de granulométrie et vitesse de jet en pulvérisation agricole ainsi que d'impact de gouttes sur des surfaces superhydrophobes illustent le propos. Une technique de calibrage des algorithmes au moyen de gouttes monodisperses est présentée.

[more ▼] Ethane (C2H6) is the most abundant Non-Methane HydroCarbon (NMHC) in the Earth’s atmosphere, with a lifetime of approximately 2 months. Its main sources are biomass burning, natural gas loss and biofuel consumption. Oxidation by the hydroxyl radical is the major C2H6 sink as it controls its strong modulation throug the year. C2H6 is involved in the formation of tropospheric O3 and in the destruction of atmospheric methane through changes in OH. C2H6 is an indirect greenhouse gas with a net-global warming potential of 5.5 (100-yr horizon). Updates of retrieval parameters such as the spectroscopic linelists have been recently published. We will therefore characterize three µ-windows encompassing the strongest C2H6 features after careful selection of these new parameters, accounting at best for all interfering species. The aim is to lessen the fitting residuals while maximizing the information content, the precision and the reliability of the retrieved product. We will present updated C2H6 total and tropospheric column time series, using the SFIT-2 algorithm (v3.91) and high-resolution Fourier Transform Infrared (FTIR) solar absorption spectra recorded with a Bruker 120HR instrument, at the high altitude research station of the Jungfraujoch (46.5°N, 8.0°E, 3580 m asl), within the framework of the Network for the Detection of Atmospheric Composition Change (NDACC, http://www.ndacc.org).

[more ▼] Laminar to turbulent transition in supersonic boundary layer is numerically investigated by combining linear stability theory and Uncertainty Quanti cation. Linear stability theory is used to determine the Nfactor for the eN transition prediction method for a Mach 6 at plate test case. Transition onset location is determined by using the Nfactor experimen- tally obtained in the facility where the test was carried out. Uncertainty quanti cation is used to compute the probability of transition within the intermittency region downstream of the transition onset. The stochastic approach allows to model the transition region as in the experimental cases since a gradual passage from the laminar to the turbulent ow is obtained. The probability of transition resembles the shape of the skin friction or the heat ux distribution generally observed in the experiments within the transition region. Here we focus on the transition zone rather than on the onset location. [less ▲] Detailed reference viewed: 31 (3 ULg) "Daz man bild mit bilden us tribe".

[more ▼] Wireworms are the soil dwelling larvae of click beetles (Coleoptera: Elateridae). Their importance as crop pests increases since the efficient chemical means to control them cannot be considered anymore. Therefore, many integrated pest management strategies have been investigated in the past few years. Most of them rely on the understanding of the ecology of the click beetles during their whole life cycle. We focus our work on the chemical ecology of wireworms, more precisely on the root-emitted volatile organic compounds (VOCs) that might intervene in the food-searching process of the larvae by helping them to find a suitable host-plant or by acting as key factors in the belowground defence mechanism of the plant. Here, we present our first results of dual-choice orientation tests in olfactometric pipes. Wireworms (Agriotes sordidus Illiger) were submitted individually to a variety of olfactory baits ranging from entire barley roots (Hordeum vulgare L. var. Quench) to isolated VOCs identified as part of the emitting profile. The latter was described thanks to HS-SPME samplings and GC-MS analysis, for roots grown in the exact same conditions as for the olfactometric experimentations with entire roots. Most of the experimentations gave significant results. When confronted to volatiles emitted by entire roots, wireworms significantly orientated towards the bait (χ²-goodness-of-fit test, χ²=8, P-value=0.005). This result allowed us to follow up with the same device and to progressively vary the nature of the baits. Our protocol should be used for other plant-wireworm species combinations. Our results should be taken into account in varietal selection, in crop rotation, or in trapping systems aiming at the reduction of the populations of wireworms.

[more ▼] Since 2006, the Millennium Challenge Account program subsidizes a project to improve the performance of the Port of Cotonou, through modernization of infrastructure and management systems, and strengthening institutional reforms. But the project mainly concerns the port, not the development of its hinterland. However, no port can develop without its links with its hinterland. That’s why we analyse the issues relating to the hinterland transport network. Thus, rail and road transportation networks will be examined. Also, we will investigate inland terminals in order to build up intermodal transportation which is almost non-operational. But in the case of freight transportation from and to the hinterland of the port of Cotonou, two uncertainties occurred. So, we have to deal with the variability of the traffic and the road capacity. Indeed, the road capacity is restricted by the level of the torrential rains in worst period, as some arcs of the road are damaged. As a first step, the objective of this paper is to determine the optimal number and locations of the terminals so that the total costs of the distribution network are minimized.

[more ▼] Depuis l’achèvement du camp retranché d’Anvers au milieu des années 1860, l’armée belge est appelée à se mobiliser et à se concentrer au cœur du pays. Elle doit en effet conserver intactes ses lignes de communication avec le principal port national, qui sert également de réduit défensif et de dépôt en vivres et munitions. Ce principe de concentration des forces est fixé dès la fin des années 1850 par Léopold Ier et son ministre de la Guerre le général Chazal. Deux raisons guident le souverain et son ministre. Premièrement, le faible nombre d’hommes appelés à servir sous les drapeaux ne permet pas d’entretenir une armée suffisamment puissante pour garnir les murs des anciennes forteresses des Pays-Bas méridionaux et défendre en même temps toutes les frontières du Royaume. A ce titre, la concentration au cœur du pays entraîne des économies d’échelle. Deuxième avantage, ce choix permet d’éviter à la Belgique des remontrances de la part de la France ou de l’Allemagne en cas de préparatifs militaires belges trop appuyés le long des frontières. Une fois rassemblée dans une position centrale, l’armée est en mesure de se porter ensuite vers la frontière menacée. Durant la guerre de 1870, le roi Léopold II est forcé de déployer l’armée belge jusque dans la pointe sud du Luxembourg afin de désarmer tous les soldats étrangers pénétrant sur le sol belge. Ce choix militaire ne va pas forcément de soi. Il découle d’une conception très pointilleuse de la neutralité belge selon laquelle tout franchissement de frontière, aussi léger soit-il, doit entraîner une réaction immédiate de la part de la Belgique. Si sur le plan du droit international, le principe d’une défense « à la frontière » paraît parfaitement légitime, il l’est beaucoup moins sur le plan stratégique. En effet, un dilemme de taille se pose aux autorités belges : en s’aventurant aussi loin du coude de l’Escaut, le risque est grand que l’armée belge ne soit coupée de sa base et encerclée au cours des combats par une percée massive de l’un des belligérants ; d’un autre côté, une projection peu audacieuse de l’armée belge risque de créer un vacuum très tentant pour les deux adversaires. Peu de temps avant le désastre de Sedan, à mesure que les combats se rapprochent de la frontière belge, la décision d’envoyer l’armée dans le sud Luxembourg n’est pas unanimement partagée. Mais la Belgique est pour ainsi dire acculée à ce choix en raison du droit international : elle doit prouver à la France et à l’Allemagne sa capacité à faire respecter sa neutralité par les armes, au risque de se voir reprocher après le conflit une passivité coupable. La Belgique doit en somme prouver qu’elle demeure bien une Barrière entre la France et l’Allemagne. C’est cette conception qui va guider la politique défensive belge à l’avenir. Sous l’impulsion de l’Inspecteur général des Fortifications et du corps du Génie Alexis Brialmont, deux ceintures de forts sont élevées autour de Liège et Namur (1887-1892). Les cités wallonnes sont en effet considérées comme les clefs stratégiques de la Meuse. En étudiant l’argumentaire belge utilisé au cours des débats précédant la construction des forts, nous constatons que la vallée de la Meuse y est présentée, tant par les milieux militaires que par les hommes politiques, comme un couloir à double porte – Liège et Namur – qu’il suffira de fermer au moment opportun. Une fois les fortifications achevées en 1892, Gouvernement et Armée paraissent convaincus que deux verrous infranchissables interdisent désormais l’accès au couloir mosan. Dans l’esprit de ses concepteurs, cette nouvelle barrière est suffisamment dissuasive pour inciter l’Allemagne et la France à ne pas violer la neutralité belge. Sur le plan diplomatique, les nouvelles fortifications sont présentées comme totalement impartiales et neutres puisque le verrou est censé être tiré autant face au sud que face à l’est ; ce qui n’était pas le cas de l’ancienne ligne de forteresses héritée des Pays-Bas, exclusivement dirigée contre la France. Notre exposé consistera dans un premier temps à rappeler ce contexte stratégique essentiel pour la bonne compréhension de notre communication. Dans un deuxième temps, à l’aide de citations choisies, nous présenterons l’image idéale véhiculée par les autorités belges concernant la frontière militaire de la Meuse. Enfin, dans un troisième temps, nous démontrerons en élargissant notre corpus de sources que cette image d’une frontière militaire parfaite – parfaite car étanche, impartiale et dissuasive – est loin d’être unanimement partagée, tant en Belgique qu’à l’étranger. La Barrière de la Meuse est-elle étanche ? Ni les opposants belges aux fortifications de la Meuse – à la tête desquels on trouve le leader libéral Frère-Orban – ni les commentateurs internationaux ne le pensent. La Barrière de la Meuse est-elle impartiale ? Elle a été conçue comme telle mais des doutes naissent rapidement en France ou en Allemagne à cet égard. La Barrière de la Meuse est-elle dissuasive ? Pas tant que cela si l’on songe qu’en dehors de la fortification du « couloir mosan », rien n’a été entrepris pour obstruer les deux autres grandes voies de communication belges entre l’Allemagne et la France : l’antique trouée du Limbourg et la nouvelle trouée du Luxembourg. C’est la raison pour laquelle, nombreux sont les commentateurs militaires – qu’ils soient anglais, français, allemands ou belges – qui continuent à spéculer sur une traversée probable de la Belgique. D’aucuns affirment même que loin de jouer un rôle de repoussoir, les nouvelles fortifications pourraient conférer à la vallée de la Meuse un intérêt stratégique qu’elle ne possédait pas auparavant.

It has become an external unifier for South American regionalism and Mercosur has considered the EU as a reference. The EU and Mercosur have planed to establish an ambitious interregional Association agreement. However, since the beginning of the twenty first century the interregional relationship is going through a period of uncertainties. Several factors are affecting it such as the incoherence of the EU policy and the EU-Brazil partnership as well as the loose of EU influence combined with the political radicalism and economic nationalism in South America.

[more ▼] Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) is an emerging tool for clinical research. MALDI MSI can be used to elucidate the relative abundance and spatial localization of peptides and proteins throughout a tissue section. For this, a matrix is applied on the tissue in either a spotted array or a homogenous coating. Acquisition of mass spectra is then carried out by performing a raster with a laser across the tissue section in a defined pattern. The spectra acquired from each position on the tissue section contain molecular weight and intensity information representative of the biomolecules at that position. One can plot the intensity of any measured ion as a function of individual pixel locations to generate m/z specific images. But, if protein desorption/ionization and subsequent MS analyses provides a measurement of molecular weight, no protein identification is performed. To achieve this, several methods have been developed. In this talk, I will first present the methods inspired by classical proteomics techniques that are regularly used to identify proteins. Bottom-up and top-down approaches have been used directly from a tissue slice, leading to the identification of some of the most abundant proteins present within the tissue slice. Then, I will present the new developments led in our lab for imaging and especially for in situ protein identification. The first example will deal with the exceptional features of FT-ICR mass spectrometry for in-source decay (ISD)-based protein identification. The benefit of mass accuracy and high mass resolution allow unequivocal assignment of ISD fragments of proteins, in the low mass range (m/z between 400 and 900), whether from pure solutions or from tissue slices. The next example is the use of a matrix “cleaning” software that reduce/remove matrix peaks thus facilitating ISD spectra analyses. Finally, proteins identification by localization and MALDI-ISD profile matching will also be a really simplistic and interesting method that will complement the immunohistological techniques commonly used to validate expression of known biomarkers within diseased tissues.

Some standard properties are preserved in this wider framework though some others are not. Yet, the advantages of these systems stem from their great generality: current research on this subject strives to highlight the properties that are independent of the target numeration system, such as properties related to the complexity of the numeration language. In this talk I will introduce this topic. In particular, I will present many open questions in the area and highlight the connections with combinatorics on words.

[more ▼] How do the phenomenal character and the intentional content of a mental state relate to one another? I discuss here the view recently supported under the label "inseparatism". My claim is that the two main suggestions made by supporters of inseparatism, namely the supervenience of the intentional upon the phenomenal and the intentional-phenomenal identity, are not compatible with a Brentanian approach. I then suggest that, for Brentano, the relationship between the phenomenal and the intentional should rather be construed as a mereological relation.

[more ▼] This study is concerning the resilience related a juvenile delinquency among victims of sexual abuse: sexual abuse has been recognized as a powerful risk factor for the emergence of deviant and criminal.behavior. Our study aims is to explore and highlight the protective factors that prevents victims of sexual abuse to engage in delinquent trajectory. The sample consists of teenage girls who have revealed at minimum last year, their intergenerational abuse position. These girls, are all between 12 and 18 years old,and divided into sub-groups: victims not offenders and victims offenders (self revealed and judicial control). Each teenage victims is compared to a normative population on different psychological’s functioning dimensions (aggression, self-esteem and pubertal timing). A comparative analysis between victims and not offenders is conducted to determine the elements that have a protective role. Clinical tests also are performed and linked to data from comparative analysis. The main factors of resilience (compared to a juvenile delinquency commitment) highlights concern the individual, the family system and the natural environment.
