Mitral and aortic regurgitations (MR and AR) are common in horses. Unlike mild valvular regurgitations, long-term prognosis of moderate or severe MR and AR is suspected to be guarded since they might induce congestive heart failure (CHF). The aim of this study is to perform a long-term follow-up of horses with moderate or severe MR and/or AR to confirm this prognosis. Firstly medical files of horses with moderate or severe MR and/or AR that had a follow-up, were retrospectively reviewed over a 15-years period (2000-2015). Clinical and echocardiographic data of 25 horses with moderate or severe MR (16/25) or AR (8/25) or both (1/25) were considered. All horses had undergone 2 or more echocardiographic exams 6 months to 10 years apart. Eight horses developed CHF (4 MR and 4 AR) and all died/were euthanized. Diastolic left ventricular internal diameter, left atrial diameter and pulmonary artery diameter were/became above reference values in 17/25 horses but no significant difference was observed between the first and the follow-up measurements (Student's t-test, p<0.05). Secondly follow-up data of additional horses with moderate or severe MR was collected by telephone survey. Owners of 27 horses agreed to answer the survey 1 to 6 years after diagnosis. Ten horses with CHF had died, 3/27 had developed CHF, 10/27 had remained clinically stable and 4/27 had died of non-cardiac causes. Results of this study confirm that moderate or severe MR and AR carry a guarded to poor long-term prognosis as 40% (21/52) of the studied horses developed CHF. [less ▲]

Traceroute is the most widely used Internet path analysis tool today to study the topology of the Internet and to diagnose routing failures as well as poor performance events. A major limitation of traceroute when the destination is not controllable by the user is its inability to measure reverse paths, i.e., the path from any given destination back to the source. This is a major drawback for ISPs, who need to understand the performance of the Internet paths connecting popular services (e.g., YouTube and Facebook) to their customers. Even if public servers and distributed measurement platforms can provide partial reverse path visibility through ad-hoc measurements, there is still a need for a structured approach capable of analyzing the performance of Internet paths connecting any pair of nodes (servers, routers, hosts, etc.). While the problem of reverse traceroute has been addressed in the past, proposed techniques rely on IP address spoofing – which might lead to security concerns, and assume the availability of certain route-tracking options –, which might not be available. In this paper, we introduce and evaluate DisNETPerf, a new tool which provides exactly the same type of information as traceroute, but for paths connecting arbitrarily selected nodes. DisNETPerf works by firstly locating probes (i.e., measurement points) that are the closest to a given target node, using them to perform traceroute measurements from the target point-of-view to a given destination for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path (from server to users) can be measured with very high accuracy in certain scenarios. We also analyze relevant characteristics of Internet paths and distributed measurement platforms, which reinforce the applicability and relevance of DisNETPerf in current Internet. [less ▲]

In Europe, ruminant processed animal proteins (PAPs) and blood products are not allowed to be used in feed for farmed animal. In contrast, blood meal and blood products of porcine origin are both authorised in aqua feed, whereas only porcine blood products are allowed to be used in feed intended for other non-ruminants. Besides official methods (light microscopy and PCR), complementary methods are developed in order to refine the by-products identification. By-products derived from blood are one of these products for which additional information are needed. Indeed, these prohibited materials sometimes cannot be distinguished from those authorised (e.g. milk powder) using official methods. The aim of this work was to develop a fast and easy method to detect blood meal and blood products. This study was based on the detection of hemoglobin in animal feed by synchronous fluorescence spectroscopy (SFS). To achieve this goal, preliminary tests were carried out on reference material (hemoglobin and albumin purchased from Sigma Aldrich) in order to determine appropriate conditions (solvent) and parameters (offset values) for hemoglobin detection. Selected settings were then applied to analyse protein extracts of commercial feed material derived from blood. The results obtained on blood meal and blood products (hemoglobin powder and plasma powder) showed fluorescence spectral bands that characterise hemoglobin. In order to determine whether the method was fit for the purpose, real commercial compound feeds known to contain or to be free from blood products or blood meal were analysed. The Principal Component Analysis (PCA) applied to these spectra showed that it was possible to discriminate samples containing hemoglobin from those that do not contain. This result confirmed that SFS is a promising screening method for the detection of hemoglobin in animal feed. [less ▲]

Background: “Less invasive surfactant therapy” (LIST), or tracheal instillation of surfactant through a small catheter in spontaneously breathing infants, is gaining popularity. Different catheters are currently used for this purpose: a nasogastric tube inserted with (LISA) or without (Take Care) Magill’s forceps, a 13 cm 16G adult angiocath (MIST), a 30 cm F4 angiography catheter (Stockholm). We developed a specific device by combining a F5 umbilical catheter and an intubation stylet (Liege). We aimed to compare those 5 devices using INSURE as a reference. Methods: 20 neonatologists from 4 institutions supporting different surfactant instillation policies intubated 2 manikin heads with the 5 catheters and an endotracheal tube in a predetermined random sequence. Water was flushed trough the catheter. Video review provided times between laryngoscope (T1) or catheter insertion (T2) in the mouth and water flowing from the trachea. Participants gave an ease of use score (range: 1-9) for each catheter. Results: Procedural times were longer with the Take Care method and shorter with the Liège device (Table). Failure rates were higher for LIST procedures than for INSURE. Take Care and LISA were rated as more difficult, while Liège, Stockholm and INSURE were considered easier. Conclusions: LIST procedures remain difficult, even on a manikin. The choice of catheter is important. A device combining the rigidity of a stylet with the soft distal end of an umbilical catheter is associated with procedures of shorter duration and is considered easier by neonatologists. [less ▲]

Introduction: Des stéréotypes négatifs liés à l’avancée en âge sont fréquemment observés en population générale. Des études ont montré que ces stéréotypes sont plus puissants que ceux liés à l’origine ethnique, au sexe ou à l’orientation sexuelle. Lorsqu’ils sont présents chez les soignants, ces stéréotypes peuvent entrainer des discriminations et limiter l’accès aux soins des personnes âgées (Schroyen et al., 2016). Il a en outre été démontré qu’un comportement d’aide injustifiée pouvait favoriser la perte d’autonomie chez une personne âgée. L’objectif de cette étude est d’évaluer la force des stéréotypes âgistes chez les étudiants en médecine et de rechercher les facteurs qui y sont associés. Méthodes: Un questionnaire écrit informatisé a été proposé aux étudiants en médecine des facultés de Rennes, Brest et Liège, de la 2ème à la 6ème année. Il associe trois mesures : l’Adaptation française de Fraboni Scale of Ageism, une tâche de fluence verbale à propos du vieillissement et de la jeunesse, et une mesure de la stigmatisation liée à l’âge par estimation de pourcentages. Résultats: Des données ont été obtenues pour 570 étudiants à Rennes et 485 à Liège; le recueil de données se poursuit à Brest. Les premières analyses confirment que l’âgisme est largement répandu chez les étudiants en médecine, avec des résultats globalement similaires à Rennes et Liège. Les étudiants de sexe masculins, ceux qui ont peu de contact avec des personnes âgées, ou qui ont des contacts jugés de mauvaise qualité, sont plus susceptibles d’exprimer des stéréotypes âgistes. Le fait d’avoir fait un stage dans un service de gériatrie ou d’avoir bénéficié d’un enseignement de la gériatrie ne semble pas influencer significativement ces stéréotypes. Conclusion: L’enseignement de la gériatrie aux étudiants en médecine doit prendre en compte la fréquence des stéréotypes âgistes. Nos résultats étant soumis à un biais de désirabilité sociale, des études portant sur les stéréotypes implicites (inconscients) seraient utiles. Une meilleure connaissance de l'âgisme et de ses déterminants chez les étudiants en médecine est nécessaire à l'élaboration d'approches pédagogiques susceptibles de limiter les conséquences de ces stéréotypes sur la qualité des soins aux personnes âgées [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.

Objective : Blood pressure (BP) control in chronic hemodialysis (HD) patients is a major challenge and could explain the controversial results about its cardiovascular risk. Our study aimed to assess the contribution of two ambulatory techniques of measurements compared with office BP (OBP): ambulatory monitoring during a maximum of 44h interdialytic period (ABPM) and home blood pressure (HBPM) during a variable period of days in prevalent HD patients. Methodology : 43 prevalent chronically HD patients (M=28; F=15), mean age 68.3±13 years were submitted to a 44h monitoring of BP (Spacelabs 90207) from the end of an HD session to 10 minutes before the next session, immediately followed by a 7days HBPM (Omron M6). Office BP was the mean of pre-dialysis BP or post-dialysis-BP recorded over 2 weeks (6 HD sessions). Hypertension was defined as BP equal or higher than 140/90 mmHg for pre-HD, 130/80 mmHg for post-HD, 130/80 mmHg for 44 h ABPM and 135/85 mmHg for HBPM. Results : Good correlations were noted between ABPM and HBPM for the diagnosis of hypertension in HD patients. Both ambulatory techniques give the same proportion of masked hypertension and white coat hypertension compared with OBP (25%). The best diagnostic precision was noted for the longest periods of recordings (44h for ABPM and 7days for HBPM). Shorter periods were more practical for the patients but less precise for high BP identification. HBPM was more appreciated than ABPM by the patients Conclusion : ABPM and HBPM identified a quarter of patients with a particular phenotype of hypertension not correctly classified by OBP. HBPM should be first recommended in HD (at least 1 week/month). As ABPM provides unique information for nocturnal BP, it could be proposed 1 time/year in all patients. [less ▲]

Background The distinction of dermatophytes strains by conventional methods is problematic due to a lack of reliable characteristics between isolates. The ability to identify individual organisms allows identification of infection sources, such as communal swimming and public washing rooms and apply appropriate control measures. Several outbreaks of dermatophytes infection have already been described in Europe and the feasibility of comparing DNA fingerprints is of interest in this particular field. We have successfully applied the rep-PCR method for typing dermatophytes species such as Microsporum audouinii, Trichophyton violaceum and Trichophyton mentagrophytes complex (T.mentagrophytes complex). Methods The Diversilab® system (bioMérieux, France) has been used to perform rep-PCR. Strains of M. audouinii (116) and T. violaceum (23) were collected during a national survey conducted by the National Reference center (NRC) for mycoses (Liège) in Belgium from February 2013 to March 2014. Strains of T. mentagrophytes complex (32) are part of the national collection of the NRC collected between 2012 and 2015. Results The Diversilab® is able to distinguish different subspecies between the same species complex as it was confirmed with the T. mentagrophytes complex. For this group of strains, two major groups are clearly visible after Diversilab analysis and correspond to white strains (ITS sequenced as T. interdigitale) and yellow strains (ITS sequenced as A. benhamiae) of T. mentagrophytes complex. Both groups share only 70% of similarity. Within a same species of dermatophyte, the Rep-PCR is also able to define several subgroups sometimes linked with epidemiological factors. Inside the T. violaceum strains circulating in Belgium, two different DNA fingerprints have been found. These two subgroups were well separated regarding the geographical location in Belgium (Wallonia and Flanders). Inside the M. audouinii species, 6 different DNA fingerprints have been detected with a main group. The degree of similarity between these six groups is comprised between 85,6% and 94%. Strains belonging to the six groups were defined as M. audouinii by ITS sequencing. Conclusion The DiversiLab® system with the Rep-PCR technology proved to be an efficient method for dermatophytes molecular typing. It is highly sensitive to discriminate small genotypic variation between two strains within the same species which is not possible with other molecular methods such as ITS sequencing. Inside the T. mentagrophytes complex, it permits to easily distinguish the yellow zoophilic strains from the white anthropophilic strain, hardly possible by microscopy. [less ▲]

Over the last decades, the Arctic has experienced a warming trend that is nearly twice as high as the global average, a phenomenon known as ‘Arctic amplification’. The impact of warmer temperatures on Arctic ecosystems is still unclear. Cyanobacteria are the key primary producers in freshwater and terrestrial Arctic ecosystems, where they are the driver for numerous ecological functions. For a better understanding of the impacts of climate change on Arctic ecosystems, baseline knowledge on cyanobacterial diversity and distribution is crucial. Here we investigate, for the first time, the biogeographic patterns of cyanobacterial communities across Svalbard, using 454 pyrosequencing of partial 16S rRNA gene sequences. Samples were taken from distinct ecosystems and biogeographic zones. We also compare the studied communities with similar Antarctic communities. [less ▲]

Nel 2011 l’UNESCO ha adottato la Raccomandazione sul Paesaggio Storico Urbano che mira al riconoscimento e all'identificazione della stratificazione e dell'interconnessione dei valori - naturali e culturali, materiali e immateriali, internazionali e locali – riscontrabili in qualsiasi città storica, concepita come un “patrimonio vivente” delle comunità. In tale visione il patrimonio culturale urbano è un elemento riconosciuto non solo dagli esperti, ma dalle intere società che ne valutano gli elementi identitari mirando a conservarli per le generazioni future. La Raccomandazione, in particolare, sostiene che per l'interpretazione e la conservazione del patrimonio culturale si può beneficiare di metodi di valutazione tradizionali e di metodi innovativi basati su dati geo-localizzati e sui dati digitali dei social media, come tweets geo-localizzati, impronte digitali e foto su Flickr. Il presente contributo illustra una metodologia basata sull’analisi delle immagini su Flickr. Dai risultati ottenuti si è evinto che proprio l’indagine dei social media può contribuire ad una comprensione significativa dei valori culturali del contesto urbano, fornendo così la possibilità di una migliore integrazione dei valori socio-culturali riconosciuti dalla collettività nei processi di conservazione e di pianificazione urbana.

In the Polar Regions, Cyanobacteria represent key primary producers and are the 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 in terrestrial biotopes. They may present interesting features to survive freeze/thaw cycles, seasonally contrasted light intensities, high UV radiations, dessication and other stresses. The BCCM/ULC public collection funded by the Belgian Science Policy Office since 2011 aims to gather a representative portion of the polar cyanobacterial diversity with different ecological origins (limnetic mats, soil crusts, cryoconites, endoliths…). It makes it available for researchers to study the taxonomy, evolution, adaptations to harsh environmental conditions, and genomic make-up. It presently includes 226 cyanobacterial strains, with 119 being of Antarctic origin (catalogue: http://bccm.belspo.be/catalogues/ulc-catalogue-search). An ISO 9001 certificate was obtained for the public deposition and distribution of strains, as part of the multi-site certification for the BCCM consortium. The morphological identification shows that the strains belong to the orders Synechococcales, Oscillatoriales, Pleurocapsales, Chroococcidiopsidales and Nostocales. The 16S rRNA and ITS sequences of the strains are being characterized. Our results show that the Antarctic strains are positioned into 25 OTUs (sequences with > 97,5% 16S rRNA similarity), and thus, represent a quite large diversity. In addition, cyanobacteria are known to produce a wide range of secondary metabolites (e.g. alkaloids, cyclic and linear peptides, polyketides) with bioactive potential. Among these bioactive metabolites, some display antibiotic, anticancer or antifungal effects. In collaboration with the BCCM/IHEM collection of biomedical fungi, a screening of cyanobacterial strains from BCCM/ULC was performed in order to discover potential new antifungal drugs. The analysis of a first set of methanol extracts from 15 different strains put in evidence the antifungal activity of a Phormidium priestleyi isolate. The latter remains active up to 0.5% (v/v) of fungal culture and was able to inhibit the growth of various fungal species among Candida, Cryptococcus, Aspergillus, and Penicillium. The raw extract was subjected to HPLC and a fraction containing the active molecule was obtained. This molecule appeared to be a thermostable hydrophobic compound. Moreover, in vitro toxicological analyses suggest that the compound has a general cytotoxic effect that could be inhibited by the mammalian metabolism. Further analyses are needed to identify the molecule and to determine if it could be a candidate for a new antifungal drug. In summary, the BCCM/ULC public collection serves as a Biological Resource Centre to conserve ex situ and document the biodiversity of polar cyanobacteria, as well as a repository for discovery of novel bioactive compounds.

The monitoring of coastal environments remains a research domain of great interest and concern. Coastal ecosystems are threatened by natural and human-induced stressors and are, as transitional environments, particularly sensitive to disturbances. EcoNum first research thematic revolves around hermatypic corals, calcifying organisms, and their adaptation potentials to environmental changes including by using original and patented chemostats. The studied organisms are grown and maintained in artificial mesocosms that simulate environmental conditions of a natural system. This infrastructure allows to perform long-term experiments, giving time to organisms to adapt to the tested conditions (e.g., increased temperature or lowered pH). Longer-term studies have demonstrated that many organisms are more resistant to environmental stressors than previously observed on the short-term. EcoNum also studies coastal plankton abundance and diversity. Plankton is particularly sensitive to physicochemical changes of water bodies. The classification and the enumeration of planktonic organisms require specialized tools in order to analyse time series of multiple samples. EcoNum has developed a software for the semi-automatic classification of planktonic organisms called Zoo/PhytoImage. This software has been used to study a 10-year time series of coastal Mediterranean zooplankton samples. The concomitant analysis of environmental parameters registered at high frequency with specific statistical tools such as the R package pastecs allows to understand the processes governing the changes observed in plankton assemblages. The use and the development of statistical tools in R (e.g., Zoo/Phytoimage, pastecs) is a priority of EcoNum to favour open access knowledge and reproductive sciences. EcoNum research topics also focus on coastal ecotoxicology. Chemicals, including trace elements, remain contaminants of concern, mainly in coastal environments that are the final sink of inland pollution sources. The chemical integrity of coastal ecosystems thus has to be accurately monitored. The partitioning of chemicals between their dissolved, particulate and sedimentary phases does not provide information on their bioavailability. EcoNum thus monitors coastal waters using bioindicator species such as seagrasses, mussels or sand worms. A global map of the contamination of the Mediterranean by trace elements has been drawn using seagrasses has bioindicator species. EcoNum also studies trace element ecology and toxicology. For instance, it has demonstrated the toxicity of copper on the coral Seriatopora hystrix and it's symbiont's photosynthetic processes, or its bioaccumulation and basipetal translocation towards rhizomes in the seagrass Posidonia oceanica as reserve nutrient for subsequent leaf growth. Finally, coastal vegetated systems are potential carbon thinks (or sources) in the global carbon cycle. Therefore, EcoNum studies the primary productivity of seagrass meadows, from the individual to the community, with measuring techniques as diverse as PAM-fluorometry or biomass production determination. To conclude, EcoNum is a research unit devoted to marine environment monitoring. It develops research thematics on major coastal communities such as coral reefs, seagrass beds or plankton assemblages and studies their natural dynamics and the effects of stressors on their global functioning.

Creating wildflower strips is often suggested as a tool to support pollinator diversity in agricultural landscapes and to promote crop pollination service. The choice of the plant species to sow in flower strips can influence the effectivity of the strips in supporting pollinators. While it has already been shown that increasing plant species diversity is beneficial for ecosystem services, it is often suggested that plant functional traits and functional trait diversity are the key for this relationship. We created a replicated field experiment with different levels of plant functional diversity in wildflower strips in Belgium to test the effect on the flower-visiting pollinator community. We sampled plant-pollinator interaction networks during 2 years and assessed how the plant functional diversity affected the network structure. Plant functional diversity did not have a clear effect on visiting pollinator species richness, however a different interaction pattern was observed with different functional diversity level. Pollinators in wildflower strips with higher functional diversity had less overlap in their ecological niche, while network stability and robustness for secondary extinctions were not affected. We discuss implications for wildflower strip design. [less ▲]

Natural soft clay exhibits a considerable degree of anisotropy as a result of its past sedimentation and consolidation history. It also tends to have significant inter-particle bonding, which affects its mechanical behavior. The natural structure of in-situ soils makes their behavior different from that of a reconstituted material. In fact, most clays lose a proportion of their strength when remoulded. Various authors proposed anisotropic elastoplastic soil models allowing the yield surface to rotate with the stress history. These models have a “rotational hardening law" which relates the change of the inclination of the yield surface to the current soil state and to the increments of the plastic volumetric and/or shear strain, [Sekiguchi and Otha (1977)], [Hashiguchi and Chen (1998)], [Wheeller et al (2003)]… Other authors combine the plastic anisotropy with destructuration effects observed in soft sensitive soils by assuming that the size and /or the position of the center of the yield surface depends on the amount of the structural soil degradation. These models use an additional isotropic hardening law that relates the size and/or the position of the yield surface of the intact sample to that of the reconstituted one [Nova et al (2003)]. The previous models provide little or no flexibility when it comes to describe the change of the plastic modulus with the loading direction as they are unable to produce a smooth degradation of the stiffness, being single yield surface models. A way to improve this behavior is to introduce the “bounding surface plasticity” theory, initially developed by Dafalias [Dafalias and Herrmann 1986]. Unlike a single yield surface model, the bounding surface theory allows a smooth transition of stresses within and on the bounding surface. The mean feature of this concept is that the actual stress is mapped to the imaginary stress on the bounding surface. The distance between the real and imaginary stress, which is called the “ function distance ”, is used to specify the plastic modulus. This work presents a bounding surface plasticity model for natural and structured clays based on the critical state theory. A novel rotational hardening rule for clays is presented, and a hardening function distance is introduced to describe the evolution of the bounding surface. Validation of the model is provided by drained and undrained tests of Scottish and Finnish intact and reconstituted clays [Kastunnen 2008]. Finally, finite element simulations of a foundation considering the formulated constitutive law are presented. [less ▲]

Le diagnostic médical d'une pathologie est un événement significatif dans les parcours de vie des patients et de leurs proches. Il vient catégoriser des symptômes, participer aux processus de (re)construction de soi, et induire des attitudes et comportements en vue d'intervenir activement sur les événements. Notamment, il correspond pour certains au moment de leur engagement au sein d'une association concernée par la pathologie ou le syndrome diagnostiqué en question. De telles associations de patients s'impliquent souvent dans diverses activités de production, de mobilisation et de circulation de connaissances sur les conditions et leurs causes. Ces modes d'activisme dits "basés sur la connaissance" (evidence-based activism) se caractérisent par une articulation étroite entre des connaissances issues d'expertise biomédicale et des connaissances expérientielles, issues des expériences vécues au quotidien par les patients et leurs proches, dont ils revendiquent la légitimité. S'inscrivant à la croisée des Science and Technology Studies et de l'anthropologie de la santé et de la maladie, la présente communication vise à explorer les dynamiques de cette articulation à partir d'une ethnographie multi-site menée auprès d'associations belges francophones concernées par des pathologies ou syndromes génétiques. Plus particulièrement, la communication s'intéresse à un projet d'information et de sensibilisation autour du trouble du spectre autistique (TSA) qui est développé par un groupe de parents concernés. Le TSA y est défini comme une condition complexe et multidimensionnelle, aux causes incertaines et controversées mais dont ils revendiquent la part déterminante de la génétique. Comment des "connaissances expérientielles" sont-elles produites, validées et mises en circulation dans le cadre de telles activités ? Au-delà de la simple information, les observations montrent qu'elles comportent des enjeux identitaires importants. [less ▲]

The analysis of the of Silva’s collection of works places us in quite a disconcerting, yet no less encouraging, position, when re-assessing the different forms of importing literary movements. On one hand, the image attributed to Silva both by his contemporaries and his successors is that of the leading figure in the assimilation and absorption of the literary European movements that would give rise to modernism. On the other hand, the absence of public visibility for Silva’s works, be it through texts or paratexts, let us in a difficult situation to prove the poet’s will to position himself as the one who introduced the new literary movement to Colombia. If we accept from the outset, as we will in this article, that the Colombian poet possessed an obstinate determination to appropriate and assimilate the European literary movements that give rise to modernism, then we must entertain the possibility that Silva’s literary transfer took place through media other than books, journals or magazines. Our hypothesis is that by focusing on the acts of reading and poise, the literary coterie became the ideal platform for the Colombian writer to adopt and propagate the image of the decadent writer, which would become the embodiment of the aesthetic ideals of modern literature.

Los escollos metodológicos encontrados a medida que avanzábamos en la problematización de nuestro corpus sirvieron pues de estímulo para integrar y transponer algunos conceptos y herramientas teóricas tomados principalmente de la teoría de los campos de Pierre Bourdieu, del análisis del discurso a la manera de Dominique Maingueneau y de la poética histórica de los soportes tal y como ha sido desarrollada en Francia por Alain Vaillant y Marie-Ève Thérenty.

Dans les années 60, Grothendieck révolutionna la géométrie algébrique en introduisant le concept de topos. Faisant face à des situations où la notion d'ouvert était trop restrictive pour comprendre les phénomènes géométriques sous-jacents, il définit une nouvelle notion de topologie dans le langage de la théorie des catégories. Très utilisée pour résoudre des problèmes de géométrie et d'analyse contemporains, cette notion a aussi de nombreuses applications surprenantes en logique (théorie intuitionniste, équivalence de Morita, etc ...). Dans ce séminaire je proposerai une application de la théorie des topos de Grothendieck pour étudier les fonctions et les distributions tempérées. En effet, ces objets ne forment un faisceau que sur une topologie de Grothendieck particulière (la topologie sous-analytique), qui n'est pas une topologie au sens usuel du terme. Je montrerai alors, de manière abstraite, comment définir un faisceau de fonctions holomorphes tempérées qui a joué un rôle crucial dans la démonstration de la correspondance de Riemann-Hilbert (généralisation du 21ème problème d'Hilbert). En particulier, ce nouveau faisceau fournira une nouvelle définition, presque purement algébrique, des distributions de Schwartz. [less ▲]

Halyomorpha halys Stål, la punaise diabolique, est une espèce invasive préoccupante en provenance d’Asie de l’Est. En moins de 15 années, elle a colonisé près de l’ensemble des Etats-Unis d’Amérique, occasionnant des pertes de rendement considérables dans les vergers et les cultures en champs ainsi que des nuisances dans les habitations durant l’hiver. La punaise diabolique a été recensée en Suisse en 2007, et il est à craindre qu’elle colonise la presque totalité de l’Europe d’ici 2020. Cette étude a pour objectif de prévenir l’installation de la punaise diabolique dans les pays européens en se focalisant sur le contrôle biologique. Des scientifiques américains ont développé une stratégie « attirer et tuer » basée sur la phéromone d’agrégation de la punaise diabolique et des pesticides. D’autres ont montré l’efficacité d’un champignon pathogène d’insectes (Beauveria bassiana strain GHA. Afin d’établir un contrôle rapide du ravageur en Europe, compatible avec l’agriculture biologique, une idée serait de combiner l’effet attractif de la phéromone d’agrégation et l’application de spores de B. bassiana. Dans cette étude, l’impact du champignon sur la mortalité de l’insecte et son autodissémination sont évalués. [less ▲]

Les pucerons font partie des insectes qui causent des dégâts d’importances économiques sur une grande diversité de plantes cultivées. Les insecticides de synthèse généralement utilisés pour les contrôler montrent de plus en plus leurs limites (résistance), et sont néfastes pour l’homme et l’environnement. Dans la recherche de méthodes de lutte alternatives, le comportement de choix d’Acyrthosiphon pisum Harris (Homoptera : Aphididae) exposé à des sources d’odeurs de plant de fèves (Vicia fabae L.) et du basilic européen (Ocimum basilicum L.) à l’aide d’un olfactomètre en Y a été étudié. Les observations de cette expérience montrent que les pucerons se dirigent préférentiellement vers la source d’odeurs de fève et y passent plus de temps. Ce résultat montre que les volatiles du basilic ont un effet répulsif sur les pucerons du pois. D’autres tests seront évalués sur des espèces de pucerons plutôt généralistes afin de valider l’effet répulsif du basilic sur les pucerons. [less ▲]

Il existe actuellement un consensus sur le fait que les scientifiques ne décrivent pas la réalité telle qu’elle est dans toute sa complexité mais qu’ils en construisent des représentations qui leur permettent de l’expliquer partiellement et de la maîtriser, partiellement également. De telles représentations sont généralement appelées des modèles et le processus de leur construction est la modélisation. Les référentiels et programmes de sciences insistent de plus en plus, dans un souci d’authenticité épistémologique, sur la nécessité de confronter les élèves aux modèles établis et à leur élaboration, afin qu’ils se constituent une vision aussi fidèle que possible de l’entreprise scientifique. Le concept de modèle possède des composantes multiples et il n’est pas aisé d’en donner une définition compacte, complète et définitive. On pourrait tenter de dire, en bref, que modéliser, c’est simplifier délibérément pour pouvoir expliquer et agir efficacement. On peut envisager différents types de modèles qui ne s’excluent pas mutuellement. On les rencontrera dans les différentes activités expérimentales que nous proposons. (i) On peut tout d’abord modéliser une situation expérimentale complexe (une pile commerciale ou un accumulateur, par exemple) par une autre situation apparentée mais plus simple et dont on contrôle mieux les paramètres, afin de mettre leur influence en lumière. Diverses expériences sur les piles (de Daniell, entre autres) illustrent cet aspect. Les expériences proposées sur la diffusion entrent également dans cette catégorie. (ii) En chimie, le principe explicatif fondamental consiste à fonder les observations macroscopiques sur des processus décrits au niveau sub-microscopique (atomes, molécules, ions, électrons). Cette représentation sub-microscopique peut être schématique et/ou symbolique. Pour plusieurs des expériences proposées, on demande de représenter schématiquement les mouvements des particules concernées. On demande aussi de traduire le phénomène en un langage symbolique, l’écriture de la réaction chimique. Ici aussi, il s’agit d’une modélisation : quand on écrit HCl(aq), par exemple, on remplace une situation complexe et relativement mal définie – des ions H3O+ et des ions Cl- hydratés avec éventuellement plusieurs couches d’hydratation – par une écriture compacte qui représente de manière conventionnelle l’essentiel de l’information dont on a besoin dans un but déterminé (un titrage, par exemple).

While representing less than 5% of the total ice cover around Antarctica, fast ice is nevertheless an important habitat with highest biomass and production occurring in the bottom (Archer et al., 1996). Sea--‐ice algae are playing a key role in structuring the ecosystem, as they are an essential food source for krill. With the annual melting of the sea ice there is a strong release of nutrients and algae to the water, possibly fertilizing and/or seeding algae the underlying water column. A time series was sampled during the Austral spring of 2015 (Oct. 27th – Dec. 11th), in the vicinity of Davis station (68°35’ S, 77°58’ E, Prydz Bay, Antarctica). Fast ice, snow cover and underlying water column were sampled with focus on the nitrogen and carbon cycle and the pivotal role of sea--‐ice algae for higher tropic levels. Different parameters such as nutrients, particulate matter (PM) and isotopic signatures for nitrate, ammonium and PM will be measured. Primary production and uptake rates for different nitrogen substrates were also measured using in--‐situ stable isotope incubation experiments to study the change in algae growth rates. That campaign was performed in close relation with colleagues from the Institute of Marine and Antarctic Studies (Hobart, Australia) to link our findings with the availability of trace metals such as iron. Temperature profiles in the ice showed a clear change halfway the sampling campaign with increasing temperatures, likely accompanied by an increase in permeability throughout the ice. Results show a large accumulation of biomass in the bottom few 5 cm (particulate organic carbon reaching up to 1300 μmol l‐1). Preliminary data also shows a large accumulation of nitrate at the bottom with concentrations exceeding those in the underlying water. Preliminary results will be presented and discussed. [less ▲]

Complex oligosaccharides from human milk (HMO) promote growth of Bifidobacterium bifidum. Oligosaccharides from cow milk (BMO), similar to HMO, are mainly represented in colostrum by 3’-sialyllactose (3’SL). Bifidobacterium crudilactis, a species from bovine origin and encoding for β galactosidases and α-glucosidases, could be able to metabolise them. Also, fermentation products could have antivirulent activity against intestinal pathogens. This study focused on capacity of bifidobacteria to metabolise 3’SL and on potential antivirulent effect of cell-free spent media (CFSM) against pathogenic bacteria. B. bifidum BBA1 and B. crudilactis FR/62/B/3 isolated respectively from breastfed children feces and cow raw milk cheese were grown on media supplemented with 3’SL as sole source of carbon. Next, CFSM effects were tested against virulence gene expression using ler and hilA promoter activity of luminescent constructs of Escherichia coli 0157:H7 ATCC 43888 and Salmonella Typhimurium SA 941256, respectively. The effect was confirmed on wild type strains of E. coli O157:H7 ATCC 43890 and S. Typhimurium ATCC 14028 using RT-qPCR. Both strains were able to grow in presence of 3’SL. CFSM resulted in under-expression of hilA and ler genes for the luminescent constructs and in under-expression of ler (ratios of -15.4 and -8.1) and qseA (ratios of -2.1 and -3.1) genes for the wild type strain of E. coli O157:H7. No effect was observed with S. Typhimurium. Little is known about CFSM metabolites and they have to be isolated and identified. The potential synbiotic effect between 3’SL and bifidobacteria will be tested using the Shime®, a human gastrointestinal model. [less ▲]

Most researches on genetic variety evaluation in Vietnamese local chicken breeds have been based up to now on microsatellite markers (Cuc et al., 2011; Pham et al., 2013). Thanks to the genotyping of ~580,000 SNPs on 95 chickens, this study aimed to assess the genetic diversity in four Vietnamese local breeds (Mia, Mong, Ho and Dong Tao). Inbreeding was examined through the detection of runs of homozygosity (ROH; Curik et al., 2014). The ROHs are long stretches of homozygous genome that are likely to reflect autozygosity. Given that Ho chickens have a small effective population size, more inbreeding and consequently longer ROHs are expected. Conversely, Mia chickens, with a larger effective population size should show less consanguinity and shorter ROHs. As expected, Mia chickens led to less observed homozygosity and less ROHs than the three other breeds. Moreover, when ROHs were subdivided in different lengths, the proportion of individuals having at least one R OH longer than 5Mb was significantly higher in Ho (63%) than in Mia chickens (33%). Given that very long ROHs are particularly associated with recent inbreeding, it seems that many Ho chickens have consanguineous parents. However, no significant difference was observed between the four breed concerning the total length of long ROHs (> 5Mb). In conclusion, the analysis of ROHs reported less consanguinity in Mia than in Ho chickens. In each breed, some individuals are found more consanguineous than expected. This study also confirms that ROHs are a useful tool in inbreeding research. [less ▲]

Le présent article s’intéresse à la reconfiguration du contrôle managérial face à une des évolutions actuelles des formes de travail, à savoir le travail à distance. Après avoir circonscrit ce concept et à partir d’une étude empirique menée au sein d’un groupe international du secteur des télécommunications, cette thématique particulière est abordée à l’aune de la sociologie de Goffman. Cette dernière s’avère singulièrement riche pour appréhender les changements, y compris digitaux, qui prennent place à l’heure actuelle dans les organisations. L’apport goffmanien est double : le propos de l’auteur constitue, d’une part, les bases de la méthodologie ethnographique de recueil des données élaborée et, d’autre part, l’éclairage théorique choisi pour discuter les résultats empiriques. Il apparaît ainsi que le contrôle managérial du travail à distance donne naissance à des situations paradoxales au sein desquelles s’opposent l’invisibilité engendrée par l’absence intra muros et l’hypervisibilité mise en place lorsque les personnes sont présentes dans les établissements physiques de l’entreprise, d’une part, et à travers les outils technologiques, d’autre part. La recommandation classique de la littérature prônant le passage à une direction par objectifs s’avère insuffisante pour répondre à l’enjeu du contrôle managérial. Les conclusions de cette recherche suggèrent davantage une hybridation réfléchie des modes de contrôle articulés autour d’une relation de confiance. [less ▲]

The YROSIAE (Year Round survey of Ocean-Sea Ice-Air Exchanges) survey aimed to carry out a year-round survey of land-fast sea ice focusing on the study of sea ice physics and biogeochemistry. Ice cores, sea water, brines material were collected at regular intervals about 1 km off cape Evans in McMurdo Sound, Antarctica, from November 2011 to December 2011 and from September 2012 to December 2012. Samples were processed to characterize both the vertical distribution and temporal changes of climate gases (CO2, DMS, CH4, N2O), CO2-related parameters (ice-air CO2 fluxes, dissolved inorganic carbon, total alkalinity and CaCO3 amount), physical parameters (salinity, temperature, and ice texture), biogeochemical parameters (macro-nutrients, particulate and dissolved organic carbon, δ13C, δ30Si and δ15N) and biological parameters (chlorophyll a, primary production within sea ice derived from O2:Ar and O2:N ratios…). Very high chlorophyll a abundance was observed at the bottom of the ice, a common feature of land fast ice in McMurdo Sound. During spring, chlorophyll a exhibited a significant increase suggesting high primary production. . However, at the same time, nutrients at the bottom of the ice increased significantly suggesting high remineralization and heterotrophy. In the middle of the ice column, evolution of dissolved inorganic carbon shown a succession of autotrophic and heterotrophic phases. However, the overall increase of DIC suggests that the ice interior was rather heterotroph. This was consistent with the increase in nutrients observed at the bottom of the ice. Such sea ice system should expel CO2. Yet, strong under saturation in CO2 in surface ice, and negative air-ice CO2 fluxes suggested that sea ice was taking up CO2 from the atmosphere. Meanwhile, measurements of N2O within the sea ice suggest that the ice was releasing N2O to the atmosphere as a result of high nitrification. On the whole land fast sea ice in McMurdo Sound appears as a puzzling ecosystem. It is able to support elevated growth of autotrophic organisms, but appears to be heterotrophic, yet pumping CO2 to the atmosphere but releasing other greenhouse gases. [less ▲]

Les environnements flexibles sont en vogue. Présentés dans la littérature managériale comme un terrain d'émancipation pour les travailleurs, gages d'un accroissement de leur autonomie et de leur liberté, ils font désormais partie intégrante des projets de modernisation. Constatant un état des lieux plus alarmiste sur cette thématique dans la littérature académique, nous mettons en question le caractère réellement émancipatoire de ce type d'espace. Par une recherche empirique, conduite dans une entreprise publique belge, nous observerons une réalité plus nuancée. Quand ils ne font pas l'objet de réformes profondes de l'organisation du travail dès le tout début du processus de changement, ce type d'agencement est susceptible de se faire au détriment des travailleurs.

La parentalité est un concept difficile à définir car il s’inscrit à la fois "dans le champ social, juridique et psychologique" [1]. De nos jours, le « devenir parent » est décrit comme un processus dynamique, qui débute dès le désir d’enfant, et qui s’accompagne de remaniements psychiques importants chez les deux parents. Depuis plusieurs années, des études se sont intéressées à l’impact de la précarité sur la sphère familiale. Il est aujourd’hui reconnu que la précarité psychosociale impacte toutes les dimensions du développement de l’enfant et plusieurs dimensions de la parentalité (sensibilité parentale, disponibilité émotionnelle, pratiques éducatives, …). La précarité est définie comme « l’absence d’une ou plusieurs des sécurités, notamment celle de l’emploi, permettant aux personnes et aux familles d’assumer leurs obligations professionnelles, familiales et sociales, et de jouir de leurs droits fondamentaux » [2]. Selon Furtos, à la précarité économique s’ajoute la précarité psychosociale et, parfois, un syndrome d’auto exclusion sociale. Selon lui, « d’un côté, l’environnement est excluant, tandis que de l’autre côté le mot « auto » renvoie à la part du sujet : tout en subissant une situation d’exclusion, le sujet a la capacité d’exercer sur lui-même une activité pour s’exclure de la situation, pour ne pas la souffrir, transformant ainsi le subir en agir » [3]. Ce public est caractérisé par une problématique du lien. Entrer en relation, s’investir dans un suivi, maintenir une continuité du lien sont autant de défis pour les parents en syndrome d’autoexclusion sociale. Parvenir à les rejoindre nécessite donc de développer des structures flexibles et créatives, tant en ce qui concerne le suivi psychosocial que la recherche. Au travers de différentes recherches-action auprès de ces familles, nous avons été confrontés à la nécessité de développer un processus de recherche basée sur le lien pour accéder tant à l’évaluation de pratiques d’intervention et à l’évaluation du vécu de ces parents. Nos travaux ont montré combien le lien occupe une place centrale dans la prise en charge et dans la recherche avec des bénéficiaires en grande précarité psychosociale.

Dans le champ intellectuel contemporain, la pensée de Paul Ricœur semble avoir pleinement intégré l’outillage conceptuel requis pour penser les identités et modes de subjectivation. Contre les conceptions du texte comme espace formel autorégulé, Ricœur a décrit le récit comme un dispositif cognitif fondamental, offrant aux individus et aux collectivités des modes de subjectivation et des prises sur le monde. Cette approche constitue un bénéfice disciplinaire non- négligeable pour les sciences humaines. Cette actualité de Ricœur peut sembler paradoxale. Certes, le concept de refiguration permet de penser les effets du récit dans le monde, à une époque où la diffusion massive d’information nécessite de capter l’attention par des récits efficaces (storytelling en politique, publicité, management, infotainment). Par contre, le concept d’identité narrative ne semble pas pouvoir se justifier de la même actualité. En effet, quoi de plus opposé à nos expériences démultipliées que cette forme narrative qui devrait les ordonner dans un récit unique ? Quoi de plus hétérogène que le vécu de l’individu contemporain, sans cesse sommé de s’adapter à de nouveaux rôles et de nouveaux projets ? Dans le cadre de cette communication, notre objectif sera d’évaluer la pertinence du concept d’identité narrative pour penser les modes de subjectivation individuelle, par le prisme de plusieurs romans contemporains (Farah, Delaume, Mérot, Minard, de Toledo, Vasset). Comment le récit de vie littéraire développe-t-il des formes qui puissent répondre aux expériences fragmentaires des sujets ? Ces formes renouvellent-elles l’usage de la narration et/ou de la fiction ? [less ▲]

Les multiples systèmes, formes, catégories et pratiques de la parenté ont retenu l’attention des anthropologues comme une dimension centrale des façons dont les individus et les groupes humains conçoivent et vivent leurs rapports à eux-mêmes, aux autres, aux sociétés et au monde qui les entoure. Dans différents contextes et périodes historiques, des évolutions – tant démographiques, politiques, socio-culturelles, économiques, juridiques, scientifiques, médicales, ou encore relatives aux âges ou aux genres – ont contribué à sa (re)définition constante. Force est de constater que les innovations récentes concernant, entre autres, les technologies de procréation médicalement assistée et de gestation pour autrui, ou les débats autour du « mariage pour tous » et de l’adoption par des couples du même sexe, ont parfois été interprétés en termes de profondes ruptures par rapport à des conceptions plus « traditionnelles » de la parenté, ce qui leur confère un certain caractère inédit et polémique. D’un point de vue anthropologique, ces reconfigurations de la parenté témoignent de différentes modalités d’articulation entre le social, le culturel et le biologique, faits de société et faits de nature, construit et inné, dans la définition de la parenté. Cela amène à repenser la parenté dans toutes ses dimensions, du public à l’intime. Partant de l’anthropologie, et afin d’élargir le champ des réflexions empiriques, théoriques et épistémologiques, ce colloque invite à croiser les perspectives sur les (re)configurations contemporaines de la parenté dans les sciences humaines et sociales en privilégiant les approches ethnographiques. Il comprend deux axes principaux mais non exclusifs. Le premier axe entend appréhender les manières dont la question des (re)configurations contemporaines de la parenté est posée dans différents espaces publics et intimes. Le second axe ouvre quant à lui un débat épistémologique sur les regards croisés et comparatifs entre divers contextes, thématiques ou disciplines en invitant à analyser les enjeux, apports et limites issus de tels travaux de recherche.

Insects are rich in proteins and could be an alternative source of proteins to feed animals. Numerous companies started the production of insects at small or larger scale as feed for chicken and fish. Most of the business models for feed production are based on the black soldier fly (Hermetia illucens) or the mealworm (Tenebrio molitor). In Europe, these novel feed are not yet authorized and products are commercialized outside Europe or eventually used as pet food (e.g. wild birds). For further authorization in Europe, many questions must be clarified concerning the presence of antinutritional compounds, the risk associated to pathogens, to residues (pesticides, antibiotics, heavy metals) and to allergens. To authorize such products on the market, methods to detect if a product really contains insects and to authenticate insect products are also mandatory. European Commission Regulation No 51/2013 named the Polymerase Chain Reaction as a reference method to determine the constituents of animal origin in feed. Targets focused on insects (target common to all insects) and targets specific to particular insect species are required. PCR methods are developed at CRA-W in this way. Among the methods developed, three of them already gave interesting results. The first one (81 bp) is specific to all insects excepting individuals from the Diptera order. The two others (94 bp and 114 bp) are specific to Tenebrio molitor. The specificity of the targets was tested against 45 insect species and on 10 commercial insect-based feed products (real-processed feed material samples). The sensitivity of the method was assessed through the AFNOR XP V03-020-2 standard approach using the LOD6 method. The three methods reached the recommended performance criteria (LOD≤ 20 copies).

Equol is a microbial metabolite of isoflavones that could be used as therapeutic agent against several diseases and cancers. Cow's milk could be a potential source of equol in the human diet, but more studies are needed on the changes in equol concentration during the technological processing of milk and dairy products. This first exploratory study sought to assess the impact of industrial skimming and microfiltration processes on equol concentration in conventional cow's milk. The milk samples used in this study came from bulk cow’s milk collected in Wallonia (Belgium), by a local dairy and processed in a local cheese factory. Six random sampling were conducted during spring and, for each of them, samples from raw, skimmed and microfiltered milk were analyzed. Equol was present in all samples at a concentration of between 3.2 and 10.3 µg.L-1. A Wilcoxon's signed rank test was then performed on the difference of data, having raw milk as reference, irrespective of the collection date. The results showed that the skimming process slightly increased the equol concentration in milk and therefore that equol had no or little affinity with the lipid milk fraction. The results also showed that, with the microfiltration process, a small proportion of equol was retained. Equol concentration has returned to the same level as that found in raw milk. This might be because of a chemical affinity either with bigger molecules that are physically retained or through direct interaction with the membrane. This scoping study paves the way for more extensive studies on the interaction between equol and other components of the milk. [less ▲]
