e probability of perceiving two objects as being similar is a negative exponential function of the distance between them in an internal psychological space (Shepard 1987). Our experimental studies showed that this distance and hence the similarity between objects in the same category is modulated by their size, frequency, and manipulability. Our experimental work also revealed that object properties evoked by digit-word expressions modulate numerosity estimations such that “8 elephants” were judged to be more numerous than “8 ants”, for instance. ese ndings extend the literature on human perceptual biases (Binet 1890) by showing that words instantly access rich mental representations. Our latest experimental ndings established that various emotional states signi cantly impact measurement estimations. [less ▲]

José Muñoz and Carlos Sampayo’s Constancio y Manolo (1976) is their seventh story featuring New York-based detective Alack Sinner. It depicts a Spanish family whose patriarch fought for the Republicans during the Civil War. It also mentions events that took place when Constancio y Manolo was being made: the US presidential election, the death of Francisco Franco and the consequent fall of Spanish dictatorship, and, albeit implicitly, the rise of a similar military, theocratic, and violent regime in the cartoonists’ native country, Argentina. The graphic style is heterogeneous, the main plot is fragmentary and numerous secondary stories interfere with its development; and yet, we are paradoxically dealing with a highlycoherent work. Muñoz and Sampayo’s poetics of fragments are put in the service of their own worldview, committed to resist against all mechanisms of oppression and expressing a deep empathy for all those left out of “economic progress”.

Preclinical molecular imaging plays a key role in the study of diseases and the development, evaluation, andvalidation of novel treatment and diagnostic techniques. The actual aim is to facilitate the translation of innovative therapies and diagnostic agents into patients by providing in vivo proof-of-principle data in animal models of diseases and accordingly match some of the legal requirements before human clinical trials. The real power of preclinical imaging stems from the fact that in vivo data are non-invasively collected, thus making longitudinal studies possible. The evolution of the disease or the actual impact of innovative treatments can be evaluated in the same animal over a long period of time. The major modalities used in preclinical molecular imaging (all present in our laboratory) are the positron emission tomography (microPET), the X-ray tomodensitometry (microCT) and the magnetic resonance imaging (microMRI). The GIGA-CRC In vivo Imaging at ULg is a multidisciplinary laboratory which relies on a medical cyclotron for radioisotope productions, a radiochemistry unit for the development of new radiopharmaceuticals and process automation, a GMP unit for radiopharmaceutical productions, a preclinical imaging unit and a clinical imagingplatform (with MRI, PET, EEG, TMS, . . . ). All expertise and qualified staff are present on site. Our laboratory has all necessary permission and approval for radiopharmaceutical productions and human clinical trials. During this presentation, we will take as an example the development of the first SV2A radioligand [18F]UCB-H (a-b) to illustrate how we can bring new ideas from the laboratory bench to the patient (Bretin, F., et al. Eur. J. Nucl. Med. Mol. Imaging Res. 2013, 3, 35; Warnock, G., et al. J. Nucl. Med. 2014, 55, 1336–1341). [less ▲]

The demethylating agent 5-azacytidine (AZA) has proven its efficacy as treatment for myelodysplastic syndrome and acute myeloid leukemia. In addition, AZA can demethylate FOXP3 intron 1 (FOXP3i1) leading to the generation of regulatory T cells (Treg). Here, we investigated the impact of AZA on xenogeneic graft-versus-host disease (xGVHD) and graft-versus-leukemia effects in a humanized murine model of transplantation (human PBMCs-infused NSG mice), and described the impact of the drug on human T cells in vivo. We observed that AZA improved both survival and xGVHD scores. Further, AZA significantly decreased human T-cell proliferation as well as IFN-γ and TNF-α serum levels, and reduced the expression of GRANZYME B and PERFORIN 1 by cytotoxic T cells. In addition, AZA significantly increased Treg frequency through hypomethylation of FOXP3i1 as well as increased Treg proliferation. The later was subsequent to higher STAT5 signaling in Treg from AZA-treated mice, which resulted from higher IL-2 secretion by conventional T cells from AZA-treated mice itself secondary to demethylation of the IL-2 gene promoter by AZA. Importantly, Tregs harvested from AZA-treated mice were suppressive and stable over time since they persisted at high frequency in secondary transplant experiments. Finally, graft-versus-leukemia effects (assessed by growth inhibition of THP-1 cells, transfected to express the luciferase gene) were not abrogated by AZA. In summary, our data demonstrate that AZA prevents xGVHD without abrogating graft-versus-leukemia effects. These findings could serve of basis for further studies of GVHD prevention by AZA in acute myeloid leukemia patients offered an allogeneic transplantation. [less ▲]

Background: SV2A is the most studied isoform of the Synaptic Vesicle 2 proteins, which are involved in the synaptic vesicle trafficking, being important in normal and pathological process, like the epilepsy (1, 2). [18F]UCB-H was developed like a tool to study the role of this isoform with neuroimaging techniques (3, 4). The objective of this study was to evaluate its specificity to this isoform comparing with the others, through a competition assay in rats with ex-vivo autoradiography and mPET imaging. Methods: Forty male Sprague-Dawley were used in ex-vivo autoradiography experiments (N=20) and in microPET imaging (N=20). Animals were pre-treated 30 minutes before the injection of [18F]UCB-H with a dose IP either of vehicle, Keppra (SV2A ligand), UCB068 (SV2B ligand) or UCB054 (SV2C ligand). Ex-vivo autoradiography was carried out 5 minutes after radiotracer injection while mPET images were acquiring with a dynamic scanner of 1 hour. Data were expressed in Standard Uptake Value and then, the area under the curve was calculated for the total process. Results: In ex-vivo autoradiography, ANOVA of two-ways showed statistical significant differences in brain uptake of [18F]UCB-H among the groups pretreated with Keppra or the ligand for SV2B and the control group. Regarding mPET data, statistical significant differences were found between the group injected with keppra and the rest of groups. Conclusion: Even if a considerable affinity between the ligands UCB068 and UCB054, and the receptor for the isoform SV2A exists, it is only detected during the first 5 minutes (ex-vivo technique), being certainly due to a nonspecific binding. This binding is not strong enough to show a direct competition with the radiotracer during a mPET acquisition. These results allow us to conclude that [18F]UCB-H is a suitable radiotracer for the imaging of the isoform SV2A in vivo, allowing us the clinical study about the molecular base of a disease with a high population impact, like the epilepsy.

Background: Graft-versus-host disease (GVHD) remains one of the major complications following haematopoietic stem cell transplantation (HSCT). Approximately 15% of the patients with chronic GVHD develop the sclerodermatous form of the disease characterized by multiple organ fibrosis and loss of skin elasticity. Several studies have shown the potential benefits of imatinib, a tyrosine kinase inhibitor, as a treatment of fibrosis in cGVHD due to its ability to inhibit simultaneously PDGF-R and c-Abl pathways which are both involved in fibrosis mechanisms. This work investigates the possible benefits of imatinib on fibrosis in a murine model of sclerodermatous chronic GVHD (sclcGVHD). Methods: Lethally irradiated Balb/cJ mice (7 Gy TBI) were injected i.v. with 10.106 bone marrow cells and 70.106 splenocytes from B10.D2 donnor mice. Mice were then treated with sterile water or imatinib (150 mg/kg/day) by oral gavage from day +7 to day +52 following transplantation. GVHD severity was assessed three times/week with a scoring system encompassing 5 criteria (mice posture, weight loss, activity, hair loss, skin integrity ; 0-1-2 point(s)/criteria). Results: Our results show that imatinib failed to prevent/improve GVHD with a similar evolution of the GVHD severity with no differences between groups. Histological analyses indicate a significant reduction of the phosphorylation level of the PDGR receptor (p = 0,033) and a trend to a decreased level of phosphorylated c-Abl (p = 0,1854). In vivo cell proliferation assay with CFSE were also performed and showed a reduced proliferation of T cells and subsets (CD4, CD8 and Tregs) in spleen, lymph nodes, bone marrow and blood after imatinib treatment. Finally, FACS analyses performed on days +21 and +35 after transplantation did not show any differences in the absolute T-cell counts. Conclusion: Although we have observed a decreased phosphorylation level of PDGR receptor and less proliferation of T cells and subsets in vivo, imatinib failed to alleviate scl-cGVHD in a murine model of severe scl-cGVHD.

Le facteur kurde dans les conflits au Moyen-Orient.. Résumé, L’objectif principal de cette communication est de montrer les enjeux politiques et sécuritaires de l’implication des Kurdes dans les conflits au Proche et au Moyen-Orient. La participation des Kurdes à la résistance à l’État islamique et leur rôle déterminant dans le conflit en Irak et en Syrie ont fortement augmenté leur poids politique. Depuis le déclenchement du conflit en Syrie la question kurde est devenue un sujet de préoccupation pour certains pays de la région qui ont peur des conséquences de la naissance d’une entité fédérale dans le Nord de la Syrie. Ceci crée un dilemme de sécurité pour la Turquie et l’Iran qui ont des convergences d’intérêt sur la question kurde. C’est pourquoi nous constatons depuis quelques mois l’intensification de la guerre entre le PKK et la Turquie et l’entrée de l’armée turque dans le Nord de la Syrie, à quoi il faut ajouter la reprise de la lutte armée du PDKI dans le Kurdistan iranien.

Antioxidants are enzymes, non-enzymatic proteins, minerals micronutrients, vitamins, phenolic compounds, pigments and others. Polyphenols have the ability to reduce or prevent damage caused by free radicals promoting positive effects on human health due to their antioxidant capacity. In this study we evaluated the content of polyphenols from several commercial biological (n = 6) and conventional juices (n = 6 ) (orange, blackcurrant, apple, grapes, tomato, carrot, pomegranate, lemon, grapefruit juices) and we determined the antioxidant effect by inhibition of the superoxide anion production measured by chemiluminescence technology. Conventional juices (orange, apple, tomato, pomegranate, lemon, grapefruit juices) showed more total polyphenolics (+ 32%), more flavan-3-ols (+ 67%) and more flavonols (+ 42%) than the same biological juices. The presence of anthocyanins was reported in juices made with blackcurrant, pomegranate and grapes only, with values above 50 µg/mL, regardless of their nature. Surprisingly, chemiluminescence results showed an inhibition in superoxide anion production by 51% for biological juices vs 23% in conventional ones. The correlation between total polyphenol content and antioxidant capacity of all the juices was r = 0.83 (r2 = 0.7). The fact that there is less polyphenols and higher antioxidant activity in bio juices could be related to the concentration and the type of polyphenol present. [less ▲]

In the actual context, biopesticides have emerged as a main alternative to conventional agriculture1. Hence, elicitors are metabolites naturally produced by microorganisms, pathogenic or not, and plants which are able to induce the natural resistance of plants. Also, they have proved to be excellent candidates for biological control. In this context, the lipoxygenase pathway leads to the formation of fatty acid degradation products, called oxylipins, which appear to be crucial agents in plant defence mechanisms2,3. Moreover, with their broad spectrum of action and their possible inducibility, oxylipins appear to be promising candidates for their use as elicitors4. This work focuses on two hydroperoxy-derived oxylipins, the 13(S)-hydroperoxy-octadecadienoic acid (13-HPOD) and the 13(S)-hydroperoxy-octadecatrienoic acid (13-HPOT). The study of the interaction of such compounds with representative plant plasma membrane lipids is essential to understand plant resistance mechanisms. Several in silico and experimental techniques of biophysics showed that acyl-hydroperoxides have significant adsorption capacity and a strong affinity for model membranes. They may also penetrate biological membrane but no permeabilisation effect was observed in this work. Slight conformational differences seem to have a significant impact on their ability to interact with plant plasma membranes. Based on these results, further investigation of the interactions of fatty acids hydroperoxides, even more on the 9-forms, with plant plasma membranes and eventually in the presence of phytopathogenic species, would allow a better understanding of the innate immunity and, on the longer term, could lead to the development of new elicitors with biological mechanisms potentially independent of membrane protein receptors.

Zinc and iron are two essential micronutrients for plants. The homeostasis networks of the two metals are intertwined. Arabidopsis halleri is a zinc- and cadmium-tolerant and zinc-hyperaccumulating species, which also present adaptation of its iron homeostasis(1,4). Transcriptomic studies identified genes which are constitu-tively over-expressed in Arabidopsis halleri compared to Arabidopsis thaliana and which may have a role in metal tolerance or accumulation(2-4). Among them, a candidate gene encodes the FRD3 (FERRIC REDUCTASE DEFECTIVE 3) protein, a member of the MATE family of membrane transporters. FRD3 is a citrate transporter involved in iron homeostasis(5-7) and plays a role in zinc tolerance in A. thaliana(8). The FRD3 gene displays a complex regulation. In A. thaliana, alternative transcript initiation for FRD3 determines two transcripts, which dif-fer in their 5'UTRs and have differential translation efficiency. The two transcripts are selectively regulated under stress conditions: iron and zinc depletion, zinc excess or cadmium presence(9). In A. halleri, a single highly ex-pressed FRD3 transcript with high translation efficiency is present(9). [less ▲]

Natural T regulatory cells (Treg) are challenging to expand ex vivo, and this has severely hindered in vivo evaluation of their therapeutic potential. 5-Azacytidine (5-azaC) and Rapamycin (RAPA) are immunosuppressive drugs that promote selectively the expansion of CD4+CD25highFoxp3+ regulatory T cells. We investigated whether 5-azaC and RAPA could be used together to promote the ex vivo expansion of Tregs purified from adult human peripheral blood. : We found that 5-azaC helped maintain FOXP3 expression during the expansion process probably by promoting the conversion of T conventional (Tconv) in Treg, instead Rapa induces selectively apoptosis in Tconv cells and expansion in Treg. Addition of 5-azaC to RAPA treated cultures improved gene expression of FOXP3, CD25, STAT5 and TGF-B resulted in enhanced Treg expansion and suppressive activity. Also Rapa and 5-AzaC combination sustain Bcl-2 protein expression in Treg conferring resistance to apoptosis process. 5-azaC may have utility in ex vivo expansion of human Tregs, not as a single agent, but in combination with RAPA. These data may considerably accelerate the development of immunotherapeutic approaches for the treatment of autoimmune disease or posttransplant alloreactions by the adoptive transfer of nTreg cells.

In the Polar Regions, Cyanobacteria are the key primary producers and main drivers of the food webs in a wide range of aquatic to terrestrial habitats. For example, they build benthic microbial mats in lakes and soil crusts. Their success in these harsh cold conditions can probably be explained by particular adaptations to survive freeze/thaw cycles, seasonally contrasted light intensities, high UV radiations, dessication and other environmental stresses. The BCCM/ULC public collection is funded by the Belgian Science Policy Office since 2011. It has obtained the ISO9001 certification for deposition and distribution of strains, as part of the multi-site certification for the BCCM consortium. This collection aims to gather a representative portion of the polar cyanobacterial diversity with different ecological origins (limnetic mats, soil crusts, cryoconites, endoliths,….) and make it available for researchers to study the taxonomy, evolution, adaptations to harsh environmental conditions, pigments, and genomic make-up. It presently includes 226 cyanobacterial strains, of which 119 are of Antarctic origin (catalogue: http://bccm.belspo.be/catalogues/ulc-catalogue-search). As shown by morphological identification, the strains belong to five orders (Synechococcales, Oscillatoriales, Pleurocapsales, Chroococcidiopsidales and Nostocales). The 16S rRNA and ITS sequences of the strains are being characterized. The first 85 Antarctic strains already studied are distributed into 25 Operational Taxonomic Units (OTUs = groups of sequences with > 97,5% 16S rRNA similarity), and thus, represent a quite large diversity. Moreover, strains identified as members of the genera Leptolyngbya or Phormidium appear in several lineages. This supports the idea that there is a need to revise the taxonomy of these polyphyletic genera with a simple filamentous morphology. To better understand the functioning, metabolism and adaptative strategies of cyanobacteria in the extreme Antarctic environment, the genome sequencing of 11 strains has been started. Pair-read data from illumina MiSeq runs were obtained and submitted to a bioinformatic pipeline dedicated to the assembly of genomes and search of sequences involved in the biosynthesis of secondary metabolites. Gene cluster prediction analysis allowed to characterize 20 clusters of NRPS, PKS and hybrid NRPS-PKS from 2 to 66kb. Surprisingly, none of the characterized operons had previously been described in the literature. [less ▲]

Les effets positifs des contextes éducatifs préscolaires sur le développement langagier des en-fants et par conséquent sur leur réussite éducative subséquente sont maintenant reconnus, particulièrement auprès des enfants provenant de milieux vulnérables sur le plan socio-économique (Dickinson, 2011). En effet, les enfants ont l’occasion d’y expérimenter de façon quotidienne des interactions riches et diversifiées avec les enseignant.es, susceptibles d’étayer leur langage (Pence et al., 2008). Or, la qualité du soutien au développement langagier offert, qui dépend entre autres de la capacité de l’enseignante à observer et à ainsi s’adapter au niveau de développement langagier de chaque enfant, est très hétérogène d’une groupe à l’autre (Bou-chard et al., 2010; Girolametto et al., 2002). En Belgique francophone, où l’orthophonie dite préventive est encore peu développée, les ensei-gnantes de maternelle font état d’un manque d’outils et de connaissances pour observer le déve-loppement langagier des enfants. L’outil SOLEM (Soutenir et Observer le Langage des Enfants en Maternelle) a été développé pour répondre à ce besoin. MÉTHODE Quatre groupes nominaux ont été réalisés auprès de 39 enseignants, agents psycho-médico-sociaux et directions d’écoles afin d’identifier leurs besoins. Un prototype de l’outil d’observation a été développé et mis à l’essai dans 10 classes pilotes, afin d’en valider la forme et le contenu. 4 enfants par groupe ont été évalué de façon parallèle avec l’Évaluation du Langage Oral (ELO), afin de faire état de la validité concurrente de l’outil SOLEM. RÉSULTATS SOLEM a été développé à partir de constats issus des groupes nominaux : accorder de l’importance aux aspects moins formels du langage, avoir une démarche en arborescence adap-tée à chaque enfant, qui mène à des pistes d’actions adaptées. Les premières mises à l’essai semblent confirmer que SOLEM répond au besoin exprimé par les enseignants.es : identifier les enfants qui ont besoin d’un soutien spécifique sur le plan du développement langagier et obser-ver leur communication pour y ajuster le soutien offert. Les résultats permettent d’aborder une réflexion sur comment l’observation du développement langagier des enfants par l’enseignant.e peut introduire la mise en place de pratiques de soutien aux habiletés langagières dans les groupes de maternelle.

The assessment of adaptive facades presents a barrier in light of the fact that there is no settled assessment technique se to systematically reach this goal. Many of the available façade performance evaluation systems or frameworks have restricted applicability for such advanced building facades. The complexity of adaptive or dynamic facades evaluation is related to the performance evaluation of façade elements, systems and overall building performance coupled to occupant behavior and occupant satisfaction. In this context, we present\s a case study for an adaptive sunscreens façade and evaluate its performance and occupant behavior. The evaluation focuses mainly on pre and post construction phase of adaptive facades: The design assist phase (including the durability test, visual mockup, onsite mashrabiya mounting and weather stripping), the commissioning phase (field verification and performance testing) and the monitoring phase. The selected project is a 150 meters high twin tower that stands with honey-comb inspired structure and automated dynamic solar screen that responds to the sun’s movement. These solar screens respond dynamically and automatically to the angle of the sun which improves the control over energy consumption, solar radiation and glare with the ability to admit natural light into the building. The paper is part of the research activities of working group 3 of the European COST Action 1403 on “Adaptive Facades “. Different methods were used for evaluation, this include: interviews with the architect and façade engineer and technical control specialist, occupants, reviews of standard and codes, review of energy models and a systematic design process mapping. A documentation of the case study describing the post construction occupant comfort, and façade operation was prepared. This paper’s audience is mainly project managers, architects, building façade engineers together with facility managers concerned with the process of design, construction and operation of adaptive sunscreens facades. The outcome of this study identifies quantifiable performance indicators and effective strategies for the design and performance evaluation of optimal adaptive facades. [less ▲]

Dans son historiographie critique (Les noms de l’histoire, 1992 / Figures de l’histoire, 2012), J. Rancière définit pour l’époque contemporaine des formes alternatives de poétique, de mise en récit et de mise en visibilité de l’histoire, qui auraient pour effet de mieux prendre en compte les anonymes et de découper autrement le sensible. Dans de nombreux textes (cf. par ex. Le destin des images, sur la « phrase-image »), Rancière étudie les formes d’accompagnement entre images et mots, et pense la figurabilité comme articulation de deux pouvoirs expressifs en un agencement spécifique. Pour échapper au débat stérile sur la préséance de l’image sur le langage (ou vice-versa), on envisagera avec Rancière l’idée selon laquelle l’image serait une « manière dont les choses parlent et se taisent ». L’image ne dit pas mieux les intensités que les mots, mais elle aménage un lieu inédit pour la mise en fiction des paroles de l’histoire. En ce sens spécifique, la figurabilité, comme mise en scène des mots et des images, doit pouvoir compter sur le travail de l’indétermination – comme on le montrera avec quelques exemples cinématographiques.

Les spéléothèmes sont maintenant considérées comme précieuses archives climatiques et environnementales sur les continents, offrant un certain nombre d'avantages par rapport à d'autres archives continentales (les sédiments lacustres, les carottes de glace….). Cette archive peut être aisément datables (U/Th, comptage de lamines et 14C), et présentent une haute résolution temporelle (décennale à saisonnière). Cependant, leur potentiel pour l'enregistrement de la pollution de l'environnement est largement inexploré et principalement axé sur la quantification des contributions d'aérosols dans des grottes touristiques. Cette étude est un des premières études qui utilise les spéléothèmes pour retracer la pollution atmosphérique. Basé sur deux spéléothèmes collectées dans la grotte de Han-sur-Lesse (S-Belgique), ce travail a deux objectifs : 1) le premier est de quantifier la concentration du Pb pour la dernière 250 ans, 2) le second objectif est de définir les sources anthropiques prédominantes de Pb en utilisant les rapports isotopiques du Pb et en basant sur les comparaisons avec les données historiques des activités anthropogéniques en Europe et la Belgique. Les concentrations en éléments traces (Al et Pb) (mesurées par LA-ICP-MS et ICP-MS) et les rapports isotopiques du Pb (mesurées par MC-ICP-MS) permettent d'identifier trois intervalles caractérisés par un enrichissement particulier en Pb : de 1880 à 1905 AD, de 1945 à 1965 AD, et de 1975 à 1990 AD. Les spéléothèmes montrent des changements similaires au niveau historique de la pollution atmosphérique connu en Belgique. Les rapports isotopiques du Pb distinguent clairement les sources de Pb et confirment que le charbon et la combustion de l'essence combinée avec des activités métallurgiques régionales étaient les sources prédominantes de la pollution au cours des 250 dernières années. Cette étude met l'accent sur la capacité des spéléothèmes d’enregistrer la pollution atmosphérique. [less ▲]

Adult neural crest stem cells (NCSC) are of extraordinary high plasticity and promising candidates for a use in regenerative medicine. Several locations like skin, adipose tissue, dental pulp or bone marrow have been described in rodent. However, very few information is available concerning their correspondence in human tissues. The main objective of this study was therefore to characterize NCSC from adult human bone marrow. In this purpose, we compared human bone marrow stromal cells to human adipose tissue and dermis, already described for containing NCSC. We performed comparative analyses in terms of gene and protein expression, as well as functional characterizations. It appeared that human bone marrow, similarly to adipose tissue and dermis contains NESTIN+ / SOX9+ / TWIST+ / SLUG+ / P75NTR+ / BRN3A+/ MSI1+/ SNAIL1+ cells and were able to differentiate into melanocytes and Schwann cells. Moreover, when injected into chicken embryos, all those cells were able to migrate and follow endogenous neural crest migration pathways. Altogether, the phenotypic characterization and migration abilities strongly suggest the presence of neural crest-derived cells in human adult bone marrow. [less ▲]

In this paper, I propose to explore the link between experience and reason in the problem of the apprehension of life. My general claim is that philosophical issues are necessarily involved in a theory of living organisms, since identifying a certain entity as a living being is to go beyond its manifestations. In part I, I argue that the empirical approach of the natural sciences cannot fully account for the peculiarity of life. In particular, I argue that the different criteria used to distinguish the living from the non-living, as those proposed in biology, are inadequate, both de facto and de jure. Indeed, they are constantly challenged by inventions of machines displaying features commonly regarded as specific to livings, and also by discoveries of new organisms whose unexpected features overcome the boundaries of our categories. More fundamentally, I hold that these criteria fail to provide sufficient conditions for qualifying beings as living, as long as the external appearances of life can, in principle, be reproduced by lifeless automatons. Therefore the phenomenological aspect of life, which cannot be accessed in a third person point of view (as the perception itself), turns out to be crucial. In the second part, I elaborate on these issues by focusing on the leibnizian theory of living beings. According to Leibniz, the distinctive feature of life is to have of a real unity, which must be conceived as the one to be found in a perceiving soul. After a brief survey on the foundations of this theory, I will emphasize how Leibniz’s attempt to account for the true unity of living beings – as opposed to the accidental unity of non-living things – exemplifies the problematic relationship between the observable properties of organized matter and the inner (or metaphysical) properties of the living as such. In Leibniz’s case indeed, the lack of empirical evidence forces him to resort to philosophical postulates, namely the principle of analogy and the principle of continuity. This latter principle allows him to qualify plants as living beings and to predict the existence of “borderline” organisms as the polyp. Finally, I will propose to consider the discovery of the polyp in the eighteenth century as a case of particular interest and a challenge to the classical conceptions of the living. Among its numerous outstanding properties, the polyp has the faculty to regenerate when cut into pieces, each of them becoming a whole new organism, and to breed by budding. Moreover, a polyp is constituted as a colony of self-contained, smaller polyps. Because of that, it is difficult to determine what the living organism exactly is: is it the colony as a whole or each of its members? And if the whole constitutes a real organism, how shall we explain its oneness? These issues raise the crucial questions of unity and individuality, which are of tremendous importance with regard to the ontological status of life. [less ▲]

Bulk superconductors can be used as trapped field magnets with unprecedented performances. Such trapped field magnets find a variety of engineering applications, in particular for brushless rotating machines and levitation devices. Compared to conventional permanent magnets, however, the magnetic field generated by a superconducting trapped field magnet is much more sensitive to the presence of an external field that is not perfectly aligned with the superconductor magnetic moment, i.e. when the external field has a transverse component. A situation where the superconductor experiences a magnetic field with a transverse component is likely to happen several times during running operation of the device. As an example, in a “trapped flux” synchronous machine, any variation of the load of the shaft may lead to a slight misalignment of the magnetic moment of the superconductor (placed in the rotor) with respect to the rotating field (generated by the stator). In such a situation, the superconductor is subjected to a rotating field, and the situation is likely to be different from a situation where the superconductor is subjected to a pure transverse field. In the present work, we aim at examining different scenarios (i.e. transverse or rotating) where the trapped field magnet is subjected to a transverse component. These configurations are examined both experimentally and numerically. The numerical model is used to determine the distribution of currents in the cross-section of the superconductor. We examine the conditions where the rotating field leads to a partial remagnetization of the sample and is therefore less detrimental that the application of a pure transverse field. We also show that the magnetic moment of the sample may behave differently that the field at the surface of the superconductor. Finally, we investigate the behavior of structures where the superconductor is attached to a thin ferromagnetic disk, and show the beneficial effect of such hybrid structures compared to the superconductor alone.

BRAIN-TRAINS is a project supported by the Belgian Federal Government that deals with the possible development of rail freight intermodality in Belgium, approaching this transport issue from an interdisciplinary perspective. Life Cycle Assessment (LCA) methodology is used to analyse the sustainability impact of rail freight intermodality. The rail freight system has been divided in three sub-systems: rail transport operation, rail infrastructure and rail transport equipment (locomotives and wagons). First, a SWOT analysis of the intermodal rail freight transport has been performed to identify internal characteristics and possible external trends of the intermodal rail freight transport. The most important elements identified in the SWOT analysis have been selected through a Delphi-technique with the collaboration of a panel of expert. Thirdly, the selected elements have been translated into clear and measurable parameters, defining for every parameter an input value to quantify the scenarios. The parameters are measured in “tonne-kilometre”. Finally, three divergent Belgian scenarios with a time horizon set in 2030 have been built for further analysis. These scenarios are directly linked to the third strategic goal of the European Commission’s White Paper on transport (2011), which aims to shift the 30% of road freight over 300 km to other modes such as rail transport by 2030. As a result, a best, worst and medium case scenarios have been developed, depending on whether the 30% shift has been successfully accomplished, the status quo has been maintained or the goal has not been completely reached by 2030, respectively. The direct transport emissions and energy consumption during the rail transport activity have been determined using the LCA methodology. These LCA results have been used to improve the accuracy of existing commercial databases as Ecoinvent for the Belgian situation. [less ▲]

Occupant tout les deux une position liminale du champ de la bande dessinée, Jochen Gerner et Ilan Manouach se sont, chacun à leur manière, livrés à des expériences réflexives de destruction de l'image en bande dessinée par le détournement. Ainsi, avec ses projets tels que TNT en Amérique, Abstraction (1941-1968), ou Le Panorama du Feu, Jochen Gerner opère par la technique du recouvrement une relecture d'albums classiques et de petits formats populaires, attirant l'attention sur certains motifs graphiques, abstraits ou figuratifs des objets détournés. Plus en phase avec l'héritage situationniste du détournement, Ilan Manouach intervient sur les œuvres appropriées pour en questionner les principes idéologiques : Katz interroge la métaphore animale au cœur de Maus, tandis qu'avec Les Schtroumpfs noirs, il retourne au thème de la représentation en imprimant l'album de Peyo entièrement en cyan. Moins politisé dans Riki fermier, Manouach y fait disparaître les personnages d'un album de Petzi pour ne garder que celui du pélican Riki, suivant un projet d'écriture à contrainte décrit comme « lipogrammatique ». Pour Gerner comme Manouach, la pratique du détournement touche directement à la matérialité de l'objet de bande dessinée, au sens où il y a une intervention physique sur les bandes dessinées détournées – que ce soit par recouvrement, retouche ou réimpression – qui se double d'un maintien du format de l'objet détourné (48 CC, pocket, pamphlet ou roman graphique). Le lecteur se retrouve ainsi face à une dé-familiarisation d'un objet pourtant connu et reconnu dans sa matérialité. Cette expérience conscientise un acte réflexif de destruction : les images d'origine se voient recouvertes de noir, rayées, masquées, retouchées, effacées, défigurées. Tout en étant extrêmement opaque, ce rapport à la matérialité est cependant différent d'autres formes de « graphiation » qui attirent l'attention sur une gestuelle physique, sur les traces de la main. Ces deux pratiques du détournement mettent en scène une destruction d'images, dont les livres en portent la trace, donnant lieu à une traçabilité différente d'une graphiation qui mettrait en avant la patte graphique du dessinateur. La mesure destructrice de cette acte de détournement se retrouve d'ailleurs en prises avec le dispositif juridique du copyright, comme l'atteste la réaction des ayant-droits à Katz, envoyé au pilon. Face à ces deux formes de destruction (destruction de l'œuvre détourné et, retour du bâton, pilonnage du détournement), MetaKatz s'offre une double portée réflexive qui couvre toute la portée du geste destructeur au cœur du détournement, un acte qui se veut en même temps être une forme d'engendrement, puisqu'il ouvre à de nouveaux dispositifs, à de nouvelles images, et à de nouvelles lectures. Notre communication mettra donc en parallèle les œuvres d'Ilan Manouach et de Jochen Gerner afin d'examiner comment la question de la destruction se trouve au cœur du détournement, et de façon plus spécifique, comment celle-ci relève d'un rapport complexe à la matérialité du médium dont nous étudierons les enjeux.

Bulk High-Temperature Superconductors (HTS) can be used as efficient passive magnetic shields with performances exceeding those of conventional ferromagnetic materials. The most common geometry for a superconducting shield is a bulk hollow cylinder. In this work, we investigate the magnetic shielding properties when the tube is not in the virgin state. Such a situation happens in practice when the tube has been initially subjected to a first magnetic field. The induced superconducting currents that are flowing in the tube generate a trapped magnetic moment which may deteriorate the shielding of a second field. Here we study experimentally how an initial trapped moment affects the shielding of a magnetic field, when they are both perpendicular to each other. In particular, we focus on the effect of an axial trapped moment on the transverse shielding performances and on the effect of a transverse trapped field on the axial or the transverse shielding performances. Finally, we show how the pristine state of the tube can be restored when applying an external field of adequate amplitude. The consequence for practical applications is that it is possible to recover shielding properties similar to those obtained in the virgin state without heating up the shield above its critical temperature TC.

Deletion of the growth hormone-releasing hormone gene (Ghrh) results in a severe deficiency of the somatotrope GHRH-GH-IGF-1 axis causing dwarf phenotype that can be reversed by GH or GHRH supplementation (Alba & Salvatori, Endocrinology 2004;145:4134). In basal conditions, the immunological phenotype of Ghrh-/- mice is not markedly disturbed except for a decrease in B cells and an increase in generation of thymic (t) Treg cells (submitted for publication). These data prompted us to investigate immune responses of Ghrh-/- mice using vaccination and infection by S. pneumoniae as models since the response to both stimuli rely on the innate immune system and B cells. Ghrh-/- mice were unable to trigger production of specific IgM and IgG against serotype 1 pneumococcal polysaccharide (PPS) after vaccination with either native PPS (Pnx23) or protein-PPS conjugate (Prev-13) vaccines. A short GH supplementation to Ghrh-/- mice (1 daily injection of 1 mg/kg GH for 4 weeks) restored IgM and IgG response to Pnx23 vaccine but not to Prev-13. This suggests that GH differently impacts on B-1, marginal zone B-2 or innate B-1 B cells. Furthermore, after intranasal instillation of a non-lethal dose of serotype 1 S. pneumoniae, Ghrh-/- mice exhibited a dramatic susceptibility reflected by bacteremia 24h after infection and a survival limit of 72 h, compared to WT C57BL/6 mice that need only 24h to clear infection. The possible impact of GH deficiency on components of the innate immune system that play an important role in defense of the respiratory tract against pneumococcal infection is under current investigation.

Production intensification of semi-intensive and intensive culture system has become a trend in the Mekong delta. However, the practice of these systems by small farm households usually results in water pollution, then placing negative consequences on aquaculture yield and quality. Water quality management is therefore nowadays one of the most important in aquaculture production in the Delta. The purpose of this paper is to investigate the water quality management of aquaculture farm households in Mekong delta then to propose the feasible solutions for better water quality management in aquacullture farm in the delta. In addition to the secondary data, a total of 32 aquaculture households at ThotNot district, CanTho province was selected for direct interviews to collect the necessary primary data. The study findings show that over 46% households rated that the quality of the pond water was more polluted than it had been 3 years ago. Several causes of the pollution are chemical residues and antibiotics; too high density of fish (especially for catfish); and no sewage system. A number of measures to manage pond water quality are initially recognized such as changing water and sucking mud of ponds after each harvest; planting trees around ponds; sprinkling lime on pond bottoms and using potassium permanganate to disinfect pond water.

The consultation is a meeting between two human beings, where one is the patient, playing the part of the sick, while the other plays the therapeutic role. It is also a meeting between knowledge and feeling. The doctor's knowledge/thoughts (true or false) influences the thoughts/knowledge (true or false) of the patient, in a dialectical relationship. In a way, the patient-doctor encounter is a meeting between science and conscience fitted in the symbolic world of human beings. The term science, as it is used here, encompasses the knowledge of the biological, the mental and the social being, as well as the observation of what is going on here and now, a cybernetic observation of the consultation itself, in a manner of speaking. Through his or her training, the doctor inevitably confronts the patient with the disease. It is his or her job to reveal it. He or she will be gratified to have, at least, found the evil, by always pushing the limits of diagnostic exploration. In an attempt to know better about what we are doing, we will go through a recent work on the main themes discussed by GPs during congresses ( www.hetop.eu/Q ) to examine which ones are dealing with the Quaternary prevention concept. We will ask to the participants if and when Quaternary prevention could exert a deep influence throughout their consultation process and their patients care pathway. [less ▲]

Quaternary prevention, as a product of the patient doctor relationships, involves actions taken to identify patients at risk of Overmedicalisation, to protect them from unnecessary medical procedures and offer ethically acceptable alternatives. Quaternary prevention, born from the meeting between two worlds of thought, two cultural backgrounds, two kinds of anxiety implies deep implications for decision about mental health issues. There is an urgent need for quaternary prevention in primary care mental health, to counter the medicalisation of normal distressing human emotions and take care with humanity of suffering human beings. The relational bases of the P4 concept are exposed. A Continual Profesional Development session (two days) of a team of 25 French GPs based in St Etienne, France (ADEPUL, CPD society, October 2016) about “Quaternary attitude and mental health” in six steps is related. Step 1; one month before the seminar : retrieving of clinical personal experiences . Step 2; sharing experiences in little groups report synthesis. Step 3; (second day) Critical reading report experts contributions. Step 4; Disease or disease mongering in mental health case reports debate. Step 5; Pros & cons trial about ADD/H, tribunal, attorney, lawyer, jury and final judgment. Step 6; After one month, exchange of modified clinical situations related by participants. [less ▲]

Creation of the Q-Codes online knowledge base The list of themes, called Q-Codes has been elaborated in a bottom-up approach, by retrieving, in a qualitative analysis study, the themes most frequently addressed by GPs when they meet in congresses. A taxonomy has been build. A multilingual terminological record has been developed for each of the 182 items identified. This work is freely available online on www.hetop.eu/Q (free access after inscription) and is supported by the Rouen (France) biomedical informatics department of the University of Rouen (France). All the data are available in the Web Ontology language (OWL-2), an ontology-ready format fit for future use in the semantic web. The product, user guide and e-learning are available on http://3cgp.docpatient.net/ The Q-codes base is aimed at several uses: • Online repository of knowledge specific to GP/FM in several languages • Online PubMed linked bibliographic system easy to use for training in GP/FM • Resource for online e-learning • Resource for analysis of content of congresses in GP/FM in joint usage with ICPC-2 and indexation of gray literature • Research area : o automatic or semi-automatic congresses indexation system o linking GP/FM to the web of data and the linked data initiative The multilingual terminology in GP/FM Out of the online database we are proud to present you the • General Practice / Family Medicine Multilingual Terminology – English version • Terminologia Multilíngue de Clínica Geral / Medicina de Família e Comunidade - Versão em Português • Terminología multilingüe de la medicina general y de familia- Versión española • Terminologie multilingue de médecine générale et de famille – Version française • Een meertalige terminologie in de huisartsgeneeskunde - Nederlandse versie • Từ điển thuật ngữ đa ngôn ngữ về y học tổng quát và y học gia đình – (Vietnamese) • -Codes and definitions will be also available online in Korean and Turkish Those 6 books (60 pages) are readable / downloadable freely online on http://3cgp.docpatient.net/ and contain an explanation of the elaboration process of the taxonomy, a tabular list of the Q-Codes, the list of their definitions and an index.

The session is devoted to the launch of an online knowledge database specific to GP / FM. This work is the result of a two years’ work of a cooperative project between participants from 12 countries and 8 languages. People are now used to the International classification of Primary Care (ICPC-2) which addresses the clinical issues in GP/FM , ie Symptoms, Process and Diagnosis. We have work on non-clinical issues i.e. all themes addressed by GPs during congresses which concern organizational, ethical, structure, teaching or patient related issues not encompassed by ICPC-2. The letter Q was used to name Q-Codes because this letter wasn’t yet used in ICPC-2. Q-codes are a classification of non-clinical items in General Practice / Family Medicine (GP/FM). Q-codes are a classification of non-clinical items in General Practice / Family Medicine (GP/FM). After a demonstration of the Q-Codes terminology and of the online database, we are proud to present to you a new GP/FM terminology in 6 languages freely available online.

Green Building movement has grown in Jordan for the last 10 year for environmental and financial reasons directly related to energy consumption and cost. Despite the few success stories, green design and green buildings are not yet the norm in the building sector in the country. One main concern for design engineers as well as investors and building owners is the extra cost green building will bring compared to traditional one. This assumption is wrong since a building cost should be analyzed through its life cycle, which not only include design and construction but also operation and maintenance costs as well. Since issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, Jordan opened a new era in the RE and EE, a changing point directly related to this law is the ability to sell electricity production to electricity companies and not only being consumers. The building sector is a direct winner if designers and engineers make right decisions. An ambitious but possible goal is to design and build Net Zero Buildings, which are buildings that produce energy as much as they consume. The aim of this paper is to provide real life cost-effective building strategies and design scenarios that will lead to a successful near Zero Energy Building in Jordan. The paper will use a representative residential apartment in the city of Amman (135- 155 m2) as the base case for the study. The design will be upgraded to include main green building strategies recommended for the climatic zone, provide loads for required systems, and test them all against performance and cost. Design scenarios will be tested and refined tell reach the best design formula that will be both functional and cost effective. The paper will provide a list of recommendations for best economically feasible design solutions and system selections that can lead to a near Zero Energy Building in Jordan for residential apartments.

Background The creation of arteriovenous fistula (AVF) may retard chronic kidney disease progression in the general population. Conversely, there is limited literature regarding the impact of AVF closure on renal function in kidney transplant recipients (KTR). Methods All KTR were retrospectively identified from 01/01/2007 to 31/12/2013, and grouped into: (0) no AVF; (1) closed AVF; and (2) left open AVF. Glomerular filtration rate was estimated (eGFR) upon MDRD and FAS equations. Linear mixed models calculated the slope and intercept of eGFR decline versus time, starting at 3 months post transplantation (Tx). Comparative analyses of eGFR slopes were performed among groups, as well as before vs after AVF closure in group 1. For the latter, time was balanced before vs after AVF closure, with at least 10 observations per patient. Results The cohort included 285 KTR (Table 1), with a median follow-up of 1750 days [1665; 2028]. Focusing on group 1, AVF closure occurred after a mean time of 653 ± 441 days post Tx, with a thrombosis/ligation ratio of 19/95. Balanced study periods before vs after AVF closure lasted 15.7 and 14.9 months, respectively. No difference was found between corresponding intercepts (p, 0.11). By contrast, eGFR slopes were significantly different before (0.043 ml/min/year) versus after (-0.176 ml/min/year) AVF closure (p, 0.0115). Similar observations were obtained using FAS equation Conclusion A significant acceleration of eGFR decline is observed over the 15 months following the closure of functioning AVF in KTR. [less ▲]

Belgium has fifteen structures included in the list of large dams of the International Committee on Large Dams. Six are managed by Engie Company, the other nine are owned by the Walloon regional public authority. The Belgian legislator has never enacted specific rules for large dams. However, managers have always been concerned with this issue. They developed procedures and methods that were subject to exchanges of experience with their counterparts, in particular through the Belgian Committee on Large Dams. In this ongoing research of security, the impact of multiple failure scenarios (dam break, quick emptying …) on the people and the environment downstream of dams is a particular focal point. An impact study has been conducted for the main plants. This study is based on a deterministic numerical method. The methodology, the assumptions regarding the failure mode or emptying and the lessons learned from the analyses are presented. These results are an important step in the assessment and the management of risks. Indeed, regulations were recently enacted for the management and the coordination of any activity likely to seriously impact public safety during crisis periods. These rules apply therefore for large dams. In this context, managers have established an emergency plan for each structure. This paper provides a broad overview on the issues of the evaluation and the management of dysfunction risks of Belgian dams, as well as on approaches and collaborations initiated between the private managers and public authority.
