In the last few years, polymer carbon nanotubes (CNTs) nanocomposites foams have received increasing attention due to their potential applications in electrostatic dissipation (ESD) and in electromagnetic interferences (EMI) shielding. To be efficient, these foams must exhibit appropriate electrical conductivity (> 1 S/m) and dielectric constant. A good understanding of the influence of the foam structural parameters on the electrical properties of the foam will ultimately enable the optimum design of these materials for the targeted applications. A wide range of poly(methyl methacrylate) (PMMA)/CNTs nanocomposites foams were synthesized using the supercritical CO2 technology. Different foaming parameters, such as the temperature, impregnation pressure, time and rate of depressurization were varied to modify the foam structure. The amount of carbon nanotubes in PMMA plays the most important role in increasing the electrical conductivity. Nanocomposite foams show higher electrical conductivity than non-foamed nanocomposites at the same volume content of CNTs. Effects of foam morphology such as cell-density; pore size, volume expansion, and cell-wall thickness on electrical conductivity were comprehensively assessed. High electrical conductivity can be achieved with nanocomposite foams that have high volume expansion, small pore size, high cell density, and thin cell-walls [less ▲]

In territorial politics, political parties are key actors – be it state-wide or regionalist parties – for constitutional reforms underlying regionalisation or federalisation processes. From the agenda-setting to the implementation of the reforms, they aggregate and catalyse territorial/national interest in order (not) to enable institutional reforms. In most representative democracies under such regionalist pressures – such as the Belgian case we explore, it is however individual MPs that ultimately vote the constitutional reforms. Of course, party discipline strongly constrains MPs’ freedom and frames parliamentary behaviour. The literature thus often explores territorial politics from a macro-perspective – political parties’ positions – rather than at a micro level – individual MPs. Yet, exploring MPs’ views on constitutional reforms bring interesting perspectives on intra-party dynamics complementing inter-party approaches. What explains MPs’ preferences on constitutional reforms? To explore this question, we surveyed every representative of Belgium’s six legislative assemblies with a standardized questionnaire (Summer 2011). We hypothesize that ethno-linguistic identity and party affiliation are strong variables explaining MPs’ preferences but that candidates’ attributes – be it (multi-level) former political experience, gender, political generation, or district origins – should also be taken into account. Based on the Belgian case study, this research will help us apprehend the rationale behind political elites’ attitudes negotiating the new boundaries of the state and above all shed light on territorial politics in Europe.

Control and optimization are major issues in ORC systems applied to waste heat sources. This talk provides an overview of the current state of the art and of the main areas of R&D in that topic, including: - Steady-state and dynamic modeling of ORC cycles (simulation platforms, modeling paradigms, numerical issues) - Optimization of the working conditions for a given heat source and heat sink, and in particular of the evaporating temperature - Optimal start-up and shut-down strategies (grid synchronization, pressure overshoot, ...) - Control of the cycle under transient heat source conditions - Traditional and advanced controllers (PID, Model predictive control) The different adjustable working conditions (condensing/evaporating temperature, superheating, subcooling, working fluid flow rate) are listed with regard to the available degrees of freedom (pump/expander speed, secondary fluid flow rates and temperatures) and their optimal values are derived, depending on the target application.

A big part of our library collections are located in a remote storage which is about 12 km from its managing library. Until recently, the only way to request a volume was by filling in a paper form at a library desk. The form was then faxed to the remote storage whose staff treated the request and delivered the ordered item to the pickup library. This workflow forced patrons to go to the library desk, no remote request was allowed. In order to modernize the workflow, we wanted to implement Aleph remote storage functionalities. We found it not so easy to set up and were faced moreover with two additional problems: we wanted to allow patrons to request (1) some items which are not in a remote storage and (2) serial issues from older collections which had never been itemized and so could not be requested through the traditional Aleph functionalities. Therefore, we set up a PHP form that any registered patron can call from the OPAC holding page (item-global) and that automatically contains patron information, bibliographic information and item details (location, call number, description, status, barcode). The patron just needs to select the appropriate pickup library before the form is sent by e-mail to the remote storage. That form can be used for any location (not necessarily for volumes located in a remote storage) and for serial holdings with few itemized volumes (a Z30 is not required to make a request). [less ▲]

Nine neurodegenerative diseases, referred to as polyglutamine diseases, are associated with nine proteins containing an expanded polyglutamine (polyQ) tract. PolyQ tracts are encoded by a repetition of the CAG codon in the corresponding genes, and are present in proteins of healthy people. They are however pathogenic when their length, due to mutations, becomes higher than a threshold generally comprised between 35 and 45Q. Such pathological tracts trigger the aggregation of the proteins into amyloid-like aggregates that could play an important role in the disease. It is therefore necessary to investigate at a molecular level the aggregation process of polyQ proteins. Since proteins associated with polyQ diseases are generally large and relatively insoluble, they are difficult to produce and handle experimentally. We have therefore decided to study the aggregation properties of polyQ proteins by designing and characterizing model proteins made of a well-characterized host protein, the β-lactamase BlaP, and polyQ tracts of different lengths (23 to 79Q) inserted either at positions 197 or 216 of BlaP. The aggregation behaviour of BlaP chimeras recapitulate those of proteins associated with polyQ diseases. We indeed observed that there is a minimal number of glutamines (i.e. a threshold) required for the chimeras’ aggregation into amyloid-like fibrils and that the kinetics of aggregation are faster with longer glutamine repeats. Most importantly, the value of the threshold for amyloid-like fibril formation seems to critically depend on the structural integrity of BlaP and thus on the constraints applied to the polyQ tract. In the present work, we investigate more deeply the role of the protein context and of oligomers on the aggregation process of BlaP chimeras. This study is mainly based on the use of two techniques: the quartz crystal microbalance with dissipation (QCM-D) in combination with atomic force microscopy (AFM), and the dynamic light scattering (DLS). QCM-D studies indicate that, under native condition, there is a minimal number of glutamines required for the elongation of BlaP197(Gln)79 fibrils by BlaP chimeras containing a polyQ tract in position 197. This threshold is lower than that observed for the aggregation assays monitored in solution in the absence of seed; it corresponds however to the threshold for fibril formation observed under denaturing conditions. These observations suggest that the conformation of BlaP is the limiting step for amyloid fibril formation by interfering with the nucleation step. BlaP chimeras containing 55Q or more in position 216 of BlaP also elongate BlaP197(Gln)79 fibrils. Interestingly this rate of cross-elongation is faster than the elongation rate observed with BlaP197(Gln)55 and BlaP197(Gln)79. This observation demonstrates that the protein environment of the polyQ tract influences its propensity to form amyloid fibrils. Finally, preliminary DLS experiments indicate that oligomers formed by BlaP197(Gln)79 under native condition are on-pathway of amyloid fibril formation and could act as aggregation nuclei. [less ▲]

INTRODUCTION: Despite the interest for the reconstruction of environmental changes over a long period of time, long-term successions have been relatively poorly investigated using a mutli-disciplinary approach compared to short-term intervals such as Kačák, Taghanic, punctata, Kellwasser and Hangenberg events. Recently, BOULVAIN et al. (2010) compared two km-thick Eifelian-Frasnian sections from Belgium and Czeck Republic using magnetic susceptibility (SM) technique. Regardless the very different background of palaeogeography, sedimentary rate, facies and local sea-level changes history, a remarkable similarity in the MS trends can be observed between these two sections. These similarities brought questions on the nature of the long-term forcing parameters that were active at the inter-regional scale. In order to get a better understanding of the factors responsible of the inter-regional forcing, a detailed records of microfacies observations, MS measurements, selected trace and major elemental concentrations and conodonts biostratigraphy have been performed on two Middle to Upper Devonian successions from Germany (Sauerland, Burgberg) and Austria (Carnics Alps, Freikofel). CONODONT BIOSTRATIGRAPHY: In the Burgberg section, conodont biostratigraphy allowed us to confirm that the studied section extend from the Middle Givetian to the Lower Carboniferous. In the Freikofel section, it allowed to precisely identify the Eifelian-Givetian and the Frasnian-Famennian boundaries. SEDIMENTOLOGY: The field and microfacies observations allowed us to reconstruct the sedimentary environment and to highlight several major variations of this environment. In the Middle Devonian, both sections are mainly characterized by fore-reef sediments. In the Burgberg section, those fore-reef sediments, mainly correspond to bioclastic grainstone and rudstone related to gravity flow deposits derived from the shallow-water area. In the Freikofel section, the fore-reef area is dominated by breccia sediments suggesting a strong debris flow influence. Through the Upper Devonian the sedimentary setting evolves to an off-reef pelagic environment in both sections and even a basinal setting in the Burgberg section. Sediments are then dominated by thin-bedded and nodular limestone. In this Upper Devonian part, locally both sections, debris coming from the shallow-water area are still observed (suggestion: Even in the Upper Devonian, occasionally debris deriving from shallow water areas has been observed in both sections. MAGNETIC SUSCEPTIBILITY AND GEOCHEMISTRY: The mean MS values for the Burgberg and Freikofel sections are respectively 1,88x10-8m³/kg and 7,72x10-9m³/kg. Compared to the MSmarine standard of 5.5x10-8m³/kg defined by ELLWOOD et al. (2011) on the basis of ~11,000 marine rocks samples, our values are low, mostly in the Freikofel section, which could indicate a low terrestrial influx seaward during the Middle and Upper Devonian. Regarding the magnetic susceptibility curves from these two sections, several large-scaled trends can be highlighted. The evolution curves of some selected clastic input proxies such as Zr, Si, Al, Ti, Sr display similar large-scaled trends. This indicates that clastic input proxies and MS are inherently linked and MS techniques can thus be used here as a proxi for changes in source or amount or type of weathering (RIQUIER et al. 2010). Most of the long-term MS variations occurring in both sections are interpreted as being related to second order eustatic variations (T-R Cycles). Through this multi-disciplinary investigation, we would like to get a better idea on the causes of long-term trends in MS variations and to document the sedimentary changes in response to these long-term variations. Further aim is to develop the application of MS techniques as a correlation tools. BOULVAIN, F., DA SILVA, A-C., MABILLE, C., HLADIL, J., GERSL, M., KOPTIKOVA, L., SCHONABL P., 2010.

We consider two kinds of questions about the successor function. The first one is concerned with the estimation of the length of the carry propagation when applying the successor map on the first n integers (or more generally on the first n elements in a given language). This leads to the notion of amortized (or average) carry propagation when applying the successor function. The second question is a computational issue: estimating the number of operations (in classical terms of Turing machines complexity) required to compute the representations of the first n integers from the first one by applying n times the successor function. This leads to the notion of (amortized) complexity, i.e., the average amount of computations required to obtain the successor of an element. [less ▲]

As part of the ICE2SEA project, the regional climate model MAR was forced by the global models HadCM3 and ECHAM5 for making future projections of the Greenland Ice Sheet (GrIS) Surface Mass Balance (SMB) over 1980-2099 at a resolution of 25km. However, the comparison with MAR forced by the ERA-40 reanalysis over 1980-1999 shows that MAR forced by these GCMs is not able to represent reliably the current SMB due to biases in the general circulation and in the free atmosphere summer temperature modelled by these GCMs around the GrIS. That is why, we present here first results of MAR forced by the next generation of GCMs from the CMIP5 data base (CanESM2, NorESM1 and MIROC5 here). The comparison with the ERA-INTERIM forced MAR simulations over current climate is a lot of better, which increases the reliability and the interest of these new MAR projections. In addition, the new scenarios (RCP 2.6, 4.5, 6.0 and 8.5) of the next IPCC Assessment Report (AR5) are used here. These new simulations show notably that the response of SMB to rising temperature is not a linear function of the temperature anomalies due to the positive albedo feedback which enhances the surface melt. For 2100, in case of extreme rising temperature (RCP 8.5 scenario), MAR simulates a surface GrIS mass loss corresponding to a cumulated sea level rise (SLR) of about 15 cm since 2000! Mainly the changes in SMB and in surface energy balance will be discussed here and estimations of the GrIS surface melt contribution to the SLR using all the CMIP5 outputs will be given. [less ▲]

We investigate some properties of abelian return words as recently introduced by Puzynina and Zamboni. In particular, we obtain a characterization of Sturmian words with non-null intercept in terms of the finiteness of the set of abelian return words to all prefixes. We describe this set of abelian returns for the Fibonacci word but also for the 2-automatic Thue–Morse word. We also investigate the relationship existing between abelian complexity and finiteness of the set of abelian returns to all prefixes. We end this paper by considering the notion of abelian derived sequence. It turns out that, for the Thue–Morse word, the set of abelian derived sequences is infinite. [less ▲]

The origin of the genitive –aes/-es for –ae is difficult to establish. The most common opinion about this type of genitive, which occurs in epigraphical and, in more reduced proportions, in papyrological sources (not, insofar as I know, in literary texts) especially for women’s personal names (but also in common nouns), is that it comes from the Greek. Beside the influence of Greek, several theories can be found about the origin of this particularity, commonly attested even in Republican Latin names. Indeed, in vulgar Latin, the –es ending genitive (used as dative as well) was frequently used from the 1st c. B.C. This phenomenon can be observed in Rome, in Italy and in the provinces (not only in western provinces, but also in eastern provinces, where the influence of Greek could have been stronger). In the epigraphical texts, this type of genitive occurs frequently in Greek personal names among some social groups (low classes). The origin of the dedicants (native, Greek or Oriental, i.e. Greek-speaking persons) must be taken into account and, for the common nouns, the contextualization is very important. I’ll focus on the inscriptions from Asia Minor and compare them with other regions as Italia X and Pannonia to see : 1° whether –aes/-es are two distinctive phenomena or two variants of the same phenomenon and 2° if this particularity has been used as a typical feature to point out the Greek origin of the person(s) mentioned in the inscription or the bilingual character of the community which has produced the text.

In the last decades, the market of goods became globalized, increasing international trade relations and the demand for long distance transportation. As a consequence of the larger distances traveled and of the containerization of goods, maritime transportation became more efficient and reliable. In the hinterland, intermodal (rail-road) freight transportation emerged as a competitive alternative to truck-only transportation. In one of its possible meanings, intermodal freight transportation is the multimodal chain of container-transportation services [1] that, e.g., brings containers from (or to) the seaport by barge or rail to (or from) an intermodal terminal in the hinterland from where they are shipped by truck to their final destination (or origin). This study focus on inland intermodal freight transport, in particular, on the rail–truck transport of cargo containers in Belgium. This European country has a long rail system and in the last years has readapted this system in order to handle with containerized cargo. Since 2004, some rail-road terminals have been built and new intermodal services between the seaports of Belgium have been established. In addition, with the aim of promoting the modal share of intermodal rail-road transport, the federal government of Belgium started subsidizing part of the rail transport cost and of the transshipments costs at the rail-road terminals. With these investments the intermodal freight flows in Belgium have increased. [less ▲]

Some non pathogenic microorganisms evolving in the root micro-environment can trigger a positive effect on plant, increasing host defense against disease or/and directly inhibiting growth of pathogen in soil (1). To initiate both phenomena leading to biocontrol activity, microorganisms use plant exudates to grow on roots and to produce in-situ active compounds. In Bacilli, cyclic lipopeptides of the surfactin, iturin and fengycin families represent important antibiotics involved in biocontrol (2). Recent studies in microbiology allowed a better understanding of plant microorganism interactions but few has been done at the molecular level. In this study, MALDI MS imaging has been used to study the nature of the secreted lipopeptide molecules, their relative quantity and their distribution in the root’s environment. Disinfected tomato seeds were first germinated at 28°C in sterile conditions for germination. Seedlings were then placed in Petri dish on ITO glass slide recovered with a thin layer of plant nutritive solution (Hoagland) containing 1,75% of agar and treated with freshly-grown cells of Bacillus amyloliquefaciens S499. Petri dishes were finally incubated vertically in phytotron at 28°C with a 16h photoperiod. Different root age / time of incubation were studied: 13 / 3; 13 / 7; 21 / 14 and 39 / 32. Control tomato root (without bacterial treatment) of the same ages were also analyzed (13 / 0; 21 / 0 and 42 / 0. For MALDI imaging experiments, the ITO slide was removed from the agar and dried in a dessiccator under vacuum. The matrix solution (α-cyano-hydroxycinnamic acid, 5mg/mL in ACN/0.2% TFA 70/30) was applied with an ImagePrep automated sprayer (Bruker Daltonics). An UltraFlex II TOF/TOF and a Solarix FT-ICR mass spectrometers were used to record molecular cartographies. The average mass spectra recorded around the tomato root (2-3 mm on both sides of the root) showed that lipopeptides were major compounds detected on the agar. The relative intensity of lipopeptides families varied with respect to the age of the root/biofilm system. In the 13/3 system, 3 homologues of surfactins were essentially detected (C13, C14 and C15), with very few iturins and fengycins. Their localizations were identical, whatever the considered homologue. Then the production of iturin and fengycin families increases in older systems (13/7 and 21/14) and a novel homologue of surfactin is detected (C12). Some variations in localizations within families may be observed (around the root or at the close vicinity of it in function of the considered homologue or alkali adduct). Then for the oldest system we studied, iturins and fengycins are not detected anymore and the localization of surfactins is less precise. In the 39/32 system, we also detected unknown compounds at 986.6, 1000.6, 1014.7 and 1028.7 m/z. The mass range of these compounds allied to the mass difference between two consecutive ion peaks let us think that these unknown compounds could be a new lipopeptide family. Investigations are in progress to identify these new secondary metabolites of Bacillus amyloliquefaciens. [less ▲]

The purpose of this research is to explore the emerging body of literature on the relationship between sustainability, strategy and management control. Our way to organise and present the literature aims to both structure the state of our knowledge in this area and stimulate others to contribute to a shared and better understanding of this field of research. Previous research has underlined that (sustainability) management control systems play a key role in shaping processes of (sustainability/CSR) strategy formulation and implementation (e.g. Simons, 1990; Epstein and Wisner, 2005; Gond et al., 2011). While the relationship between management control systems and strategy has widely been investigated in the traditional accounting and control literature (e.g. Simons, 1990; Langfield-Smith, 1997; Ferreira and Otley, 2009; Tucker et al., 2009), this is much less frequent in the context of research related to the concept of sustainability. Indeed, until recently social and environmental accounting research has predominantly paid attention to external reporting and accountability (e.g. Albelda, 2011; Gray, 2002) or the link between corporate social responsibility/environmental management and economic performance (e.g. Henri and Journeault, 2010). Conscious of this situation, several researchers have stressed the need for research on the interrelation between sustainability, strategy and control (Parker, 2000; Chung and Parker, 2008; Durden, 2008) and a growing body of literature has emerged over the last years. We hope that in reviewing and reflecting on how this emerging body of literature is organised we can contribute to a better understanding of our current knowledge and to the development of new knowledge in the future. The paper thus also aims to suggest future directions for research. Our interest in reviewing and codifying the literature is also driven by a practical need to further embed sustainability into organisations. Until today, it seems that many organisations are still confronted with difficulties in “operationalising” sustainability and translating their strategic aspirations for sustainability into practice in the midst of many other business pressures (Epstein and Roy, 2001; Schaltegger and Wagner, 2006; Taplin et al., 2006; CIMA and Accenture, 2011).

The cataract corresponds to the total or partial opacification of the lens of the eye preventing the passage of the light. At present, the surgery is the only effective treatment to overcome the cataract. The surgical intervention consists in removing the cloudy lens and to replace it by an artificial intraocular lens (IOL). The in vivo implantation of these synthetic lenses involves the evaluation of several factors as their physico-chemical properties, their capacities to interact with lens epithelial cells and proteins, as well as their biocompatibility. During a previous study, we demonstrated major differences concerning the tackiness (atomic force microscopy), the cellular adhesion and the protein adsorption of various polymer disks intended for the manufacturing of intraocular lenses. The aim of this work was to correlate a histological analysis to a mass spectrometry imaging analysis performed on the same sample. To estimate the biocompatibility of the biomaterials, an animal testing was realized in rabbits. The various polymers were implanted subcutaneously. After one month, the 2 cm x 3 cm pieces of rabbit skin and underlying muscle with a 2 cm thickness were removed, fixed with formaldehyde 10% during six days, treated for the paraffin inclusion and stored at room temperature until use. Slices of 5 µm thickness were performed using a microtome. Paraffin was removed and tissue sections were washed in graded ethanol baths. The slices were then stained with the hematoxylin and eosin dyes. The analysis of stained sections showed different histo-morphological features according to the implanted polymer. For MALDI MSI purposes, on tissue protein digestion was performed using trypsin (1) and the MALDI matrix (α-cyanohydroxycinnamic acid, 5 mg/mL in ACN/0.2% TFA 70:30) was deposited using an ImagePrep automated sprayer (Bruker Daltonics, Bremen, Germany). Experiments were carried out using an UltraFlex II TOF/TOF mass spectrometer (Bruker Daltonics, Bremen, Germany). MALDI imaging can show the detection of different proteomic profiles according to the tested biomaterials, which may be considered as biocompatibility markers. The MALDI images of these markers are then correlated with the histo-morphological profiles. Consequently, mass spectrometry imaging can become a powerful tool in the evaluation of the biocompatibility of artificial implants in biomedical application. [less ▲]

Cette intervention se propose de retracer les moments décisifs de la construction de la théorie de l’image didi-hubermanienne. Celle-ci se décline en deux temps (esthétique du symptôme / politique de l’image), jalonnés de rencontres avec des auteurs dont l’influence est manifeste (Panofsky, Freud, Warburg, Benjamin). En automne 2006, la revue Vacarme (n°37) proposait à ses lecteurs un entretien avec Georges Didi-Huberman (mené par Pierre Zaoui et Mathieu Potte-Bonneville). Au milieu de l’entretien, surgit la demande suivante : « Permettez-moi de vous poser la question un peu brutalement : quel est votre rapport réel à la politique ? […] Il semble que vous entreteniez un rapport extrêmement subtil, mais du même coup peu lisible au premier coup d’œil, à la chose publique et à la question des rapports sociaux en général. […] Il semble que vous vous arrêtiez toujours aux frontières de l’engagement, à la fois pour des motifs à la Foucault – ne pas s’emparer de la parole et de l’image de ceux qui souffrent ou agissent – et pour des motifs plus "indicibles" ». La réponse de Didi-Huberman n’est pas – à cet endroit du moins – bouleversante d’originalité : il faut bien dit-il reconnaître sa limite sur certains dossiers de l’actualité – s’engager à tout va, sans connaître les problèmes de première main, ne servirait à rien. Il admet : de nature contemplative, le rapport aux images semble d’abord coupé de l’action. Mais par ailleurs, le théoricien de l’image ne peut se résoudre à la fascination d’un monde visuel replié sur lui-même. Il faut bien qu’il sorte du musée, de la bibliothèque, de l’atelier d’artiste, pour plonger au cœur du réel et se contraindre à affronter ses aspects les plus inquiétants. Mettre les images au contact du réel, voilà la tâche la plus difficile : « L’inquiétude du contact entre l’image et le réel n’est autre qu’une accession à la dimension politique des images » . Depuis cet entretien, Didi-Huberman a développé une « politique de l’image » plus explicite, avec deux ouvrages en 2009 : Quand les images prennent position (premier volume d’un cycle intitulé L’œil de l’histoire – en trois volumes désormais tous publiés) et Survivance des lucioles (autour de Paolini). À nouveau marqué par le souffle critique de Walter Benjamin, ce dernier texte permet à son auteur de se situer très clairement dans le champ de la réflexion politique sur l’image – en prenant, surtout, ses distances à l’égard de la pensée « apocalyptique » de Giorgio Agamben. Tel est bien l’argument décisif de Survivance des lucioles : face au constat tragique du « dépérissement culturel » de nos sociétés actuelles, deux attitudes sont possibles. Soit on souligne le pire, en reprochant aux images leur pacte secret avec le pouvoir aliénant, et on prend le ton défaitiste du chroniqueur de la fin des temps, attendant désespérément une rédemption venue d’on ne sait où. Soit on souligne les efforts de résistance, les lueurs du contre-pouvoir et la « capacité de suspension, de transformation, de bifurcation » de l’image s’insérant dans la sphère politique. Mais on ne peut pas parler pour autant d’un « tournant politique » de l’esthétique didi-hubermanienne, tant les thèmes aujourd’hui avancés dans les ouvrages récents font écho aux premières interventions. Le débat épistémologique entamé très tôt avec les maîtres à penser de l’histoire de l’art traditionnelle montrait déjà à quel point les opérations théoriques relatives aux images (décrire, interpréter, analyser, retracer l’histoire) sont lourdes de conséquences d’un point de vue idéologique. Je voudrais faire voir la continuité très nette que l’on peut établir entre l’esthétique du symptôme et la politique de l’image. [less ▲]

The wild boar (Sus scrofa L.) population has increased in most parts of Europe during the last three decades. As a consequence, population distribution ranges have shifted to more agricultural areas. These newly colonized areas are characterized by highly fragmented forest cover and a preponderance of crop fields and grasslands, thus increasing the risk of problematic interactions with farming activities and small game species. Although plasticity of wild boar to various environmental conditions is well known, understanding the ecological patterns that promote the density distribution of the species within agricultural areas remains of importance for adapted management strategies within these landscapes. Inside a recently occupied area (between 10-30 years of wild boar regular presence) of southern Belgium, we studied the relation between occurences of wild boar population, estimated by hunting bag and crop damages, with a set of environmental, anthropic and landscape variables. We used Maximum Entropy (MaxEnt) approach to analyze the data. Considering the main factors known to favour wild boar distribution, we hypothesized that crop fields providing cover and food, deciduous forest (providing mast) and water stream density are the main factors influencing the wild boar density distribution. The results are used to derive a habitat suitability map of wild boar distribution in northern Wallonia where wild boar recently starts to spread. [less ▲]

Metagenomic analysis is a new culture-independent approach for assigning a taxonomic, genic or functional identity to bacterial DNA fragments of unknown origin. Its power and utility is increasingly rising thanks to the next generation sequencing techniques. It is now mature and cheap enough to be transposed to more applied fields like the food microbiology. We demonstrated in several studies the extraordinary potential of the targeted metagenomic analysis to different problematics related to food products. First, this approach is highly useful for the validation of the shelf life of food products. We analyzed standardized pork minced meat and meat product samples packaged either under modified atmosphere (MAP - 30% CO2, 70% O2) or under permeable atmosphere packaging, stored at different temperature (4°C, 4-8°C and 12°C) until the end of shelf-life. The metagenomic analysis allowed to identify species of all the sub-dominant bacterial populations. This approach showed why MAP can improve meat quality by favoring certain species rather than others. As a second example, we sought to identify the potential spoiling bacteria in several food products like raw fish, rind cheese or vacuum packed beef meats in order to illustrate the usefulness of metagenomics for the quality control of food preparations. Samples from various food matrices were screened to identify the bacterial contaminants. We combined the bioinformatics analysis with a classical approach to generate effective quantitative data for the various bacterial populations detected. This analysis characterizes the samples both on the identity of the potential spoiling bacteria present and on the quantification level of the contaminants. Finally, the metagenomic analysis reveals the presence of numerous uncultured and uncharacterized bacteria. The use of a carefully designed analysis pipeline has been used to ensure to label the bacterial population with a precise taxonomic identity and to determine whether the targeted population corresponds to a known species or not. This way, even if the nearest known homologous sequence is an environmental sample, its relatedness to known species can be deduced. This represents a new tool to trace yet uncharacterized food spoiling bacteria. [less ▲]

Nous proposons de réaliser une analyse du Rorschach d’un sujet schizophrène en phase de stabilisation. Le protocole ne répond pas aux critères de validité (moins de 14 réponses et refus de planche à 3 reprises) et ne permet donc pas de réaliser une analyse structurale complète selon les recommandations du Système Intégré. Cependant, une étude que nous qualifierons de « phénoménologique » se révèle intéressante. En centrant notre réflexion sur le processus de médiation cognitive, que le sujet emploie de manière idiosyncrasique lorsqu’il est confronté à la consigne du test, nous observerons que la démarche implicite de « fausse perception » qui est suggérée au sujet (« qu’est-ce que cela pourrait-être ? ») semble difficilement tolérable. La principale particularité de ce protocole consiste en une remise en question par le sujet des éléments perçus, pour finir, la plupart du temps, par rejeter la réponse fournie. Le recours à ce « doute méthodique » est superposable à ce que les théorisations modernes de la psychopathologie phénoménologique appellent l’« hyper-réflexivité schizophrénique » (Sass, 1992, 1994, 2001 ; Stanghellini, 2006). Nous pouvons également réaliser un rapprochement entre ce processus perceptif et les théories du « salience syndrome » développées par la neuropsychologie sociale (Van Os, 2009 ; Van Os & Kapur, 2009). Ces considérations nous permettent de rediscuter la pertinence de la remédiation cognitive basée sur la connaissance de la maladie et la reconnaissance des symptômes associés à laquelle a été soumis le patient. L’analyse du Rorschach nous donne également des informations intéressantes sur la stabilisation symptomatologique de notre patient et sur la composante résiduelle de son trouble schizophrénique. Ces observations semblent incompatibles avec des hypothèses homéostatiques et la possibilité d’un retour à un état antérieur à la schizophrénie, et démontrent l’utilité du diagnostic de schizophrénie résiduelle. Enfin, cette présentation cherchera à construire des ponts entre la méthode du Système Intégré et la psychopathologie phénoménologique moderne. [less ▲]

The debate around the construction of the Museum of Modern Art in Brussels in the 1960’s and 70’s is the most revealing illustration of the urban struggle between « the ancients and the moderns”, in which the associations play a crucial part besides the public authorities. From the beginning of the 1960’s, the implantation of the new building is the subject of numerous discussions where the “Ligue Esthétique”, a very conservative association proceeding from the Social Christian Party, founded in 1953, conflicts with the modernist designs of the Minister of Culture Pierre Wigny. Supporting the idea that the container should reflect the content, the Minister appoints the young architect Roger Bastin, whose project is also supported by the museum curator Philippe Roberts-Jones and the association “Les Amis des Musées”, lead by Count René Boël and comprising art patrons and lovers. Situated in a very delicate area of the city, besides the 18th century Place Royale and the Palace of Charles de Lorraine, the project plans the demolition of a historical building block occupied by dwellings and shops, and its replacement by a sculptural concrete building indicating the presence of the museum, almost entirely subterranean. This option earns the project the opposition of two more associations, which arise at the end of the 1960’s with very different backgrounds and aims. The “Quartier des Arts”, composed of members of the industrial aristocracy, politicians and public authorities representatives, is founded in 1967 with the aim of preserving the heritage of the area. Advised by the archaeologist and conservation expert Raymond Lemaire, the association is opposed to the demolition of one of the last ancient districts of Brussels. The ARAU (Atelier de recherche et d’action urbaine), founded in 1969 by the left wing sociologist René Schoonbrodt, fights for the maintain of the housing function of the city centre. The joint action of these very different groups of interest leads to a new version of the project and the giving up of the concrete signal building. But due to the length of the debates, more than a half of the ancient buildings have to be demolished and the other are very strongly restored: neither contemporary architecture, nor ancient heritage has won this urban battle. If the result of this long story seems today very disappointing as to urban design, the study of its mechanism is, on the other hand, particularly interesting: it reveals, through archival research, the complex relations between public and associative actors, where ideological and political considerations mix with personal – or even familial – relations and the hazards of urban life.

Some non pathogenic microorganisms evolving in the root micro-environment can trigger a positive effect on plant, increasing host defense against disease or/and directly inhibiting growth of pathogen in soil (1). To initiate both phenomena leading to biocontrol activity, microorganisms use plant exudates to grow on roots and to produce in-situ active compounds. In Bacilli, cyclic lipopeptides of the surfactin, iturin and fengycin families represent important antibiotics involved in biocontrol (2). Recent studies in microbiology allowed a better understanding of plant microorganism interactions but few has been done at the molecular level. In this study, MALDI MS imaging has been used to study the nature of the secreted lipopeptide molecules, their relative quantity and their distribution in the root’s environment. Disinfected tomato seeds were first germinated at 28°C in sterile conditions for germination. Seedlings were then placed in Petri dish on ITO glass slide recovered with a thin layer of plant nutritive solution (Hoagland) containing 1,75% of agar and treated with freshly-grown cells of Bacillus amyloliquefaciens S499. Petri dishes were finally incubated vertically in phytotron at 28°C with a 16h photoperiod. Different root age / time of incubation were studied: 13 / 3; 13 / 7; 21 / 14 and 39 / 32. Control tomato root (without bacterial treatment) of the same ages were also analyzed (13 / 0; 21 / 0 and 42 / 0. For MALDI imaging experiments, the ITO slide was removed from the agar and dried in a dessiccator under vacuum. The matrix solution (α-cyano-hydroxycinnamic acid, 5mg/mL in ACN/0.2% TFA 70/30) was applied with an ImagePrep automated sprayer (Bruker Daltonics). An UltraFlex II TOF/TOF and a Solarix FT-ICR mass spectrometers were used to record molecular cartographies. The average mass spectra recorded around the tomato root (2-3 mm on both sides of the root) showed that lipopeptides were major compounds detected on the agar. The relative intensity of lipopeptides families varied with respect to the age of the root/biofilm system. In the 13/3 system, 3 homologues of surfactins were essentially detected (C13, C14 and C15), with very few iturins and fengycins. Their localizations were identical, whatever the considered homologue. Then the production of iturin and fengycin families increases in older systems (13/7 and 21/14) and a novel homologue of surfactin is detected (C12). Some variations in localizations within families may be observed (around the root or at the close vicinity of it in function of the considered homologue or alkali adduct). Then for the oldest system we studied, iturins and fengycins are not detected anymore and the localization of surfactins is less precise. In the 39/32 system, we also detected unknown compounds at 986.6, 1000.6, 1014.7 and 1028.7 m/z. The mass range of these compounds allied to the mass difference between two consecutive ion peaks let us think that these unknown compounds could be a new lipopeptide family. Investigations are in progress to identify these new secondary metabolites of Bacillus amyloliquefaciens. [less ▲]

The Gulf of Corinth in Greece is an active continental rift propagating westward toward the Aegean subduction zone. GPS data shows that deformation rate reaches a maximum of 15 mm/yr at its western tip. The style of extension and strain distribution is well documented offshore in the eastern and central parts of the rift (Bell, 2009). At its most active western extremity, published offshore data is not sufficient to characterize the deformation pattern. High resolution seismic profiles were thus acquired in that region within the framework of the SISCOR project to improve our understanding of fault evolution, seismicity and to be able to construct mechanical models of deformation. Here we investigate the spatio-temporal pattern of the basin subsidence and deposition with sparker data acquired in November 2011. Active faults and correlative time horizons were first mapped. The stratigraphy was then correlated with the eustatic sea-level curve. This sequence stratigraphic interpretation is possible because there are strong glacial-interglacial variations in the depositional environment. In fact lacustrine conditions prevail within the gulf during glacio-eustatic lowstands and are characterized by low amplitudes seismic facies. So synrift sediment isopachs over the last 12 000 and 130 000 yrs could be produced. The interpreted data allow us to: (1) compare deformation pattern at the western tip of the Gulf with the more mature central and eastern part of the Rift; (2) constrain the pattern and the timing of deformation as well as rates of faulting.

We introduce the concept of constant 2-labelling of a weighted graph and show how it can be used to obtain periodic sphere packing. Roughly speaking, a constant 2-labelling of a weighted graph is a 2-coloring (black and white) of its vertex set which preserves the sum of the weight of black vertices under some automorphisms. In this manuscript, we study this problem on weighted complete graphs and on weighted cycles. Our results on cycles allow us to determine (r,a,b)-codes in Z^2 whenever |a-b|>4 and r>1. [less ▲]

Patients suffering from liver metastases are diagnosed late and have a poor outcome. Targeted therapies are promising treatment options, however the malignant lesions are heterogeneous in nature offering niches for cancer cells to survive and regrow. A rational strategy is needed to select targetable antigens that would overcome this intra-tumoral heterogeneity. MALDI-MS imaging is an emerging tool to study the distribution of biomolecules in tissue samples and is a good base for defining the regions of interest (ROI) that deserve further in-depth analysis. We employed MALDI-MS imaging of colorectal liver metastasis to identify ROI and guide the proteomic analysis for a more in-depth picture of modulated proteins. The focus was laid on cell membrane and extracellular proteins as these have enhanced potential to be used for targeted therapy and clinical imaging applications. Four defined ROI were further analyzed employing 2D-Nano-UPLC-MSe methodology. Over 1500 unique proteins were statistically divided into different patterns of expression, generating a quantitative picture of the proteome heterogeneity in liver metastases. The results offered insight into novel targets but also antigens against which the antibodies are already involved in cancer clinical trials. Following immunohistochemistry based validation experiments, certain proteins demonstrated the potential to homogeneously cover the metastatic lesion and become better targets. Two such antigens, LTBP2 and TGFBI were selected for in vivo functional/ tumor targeting studies in colorectal carcinoma animal model. Importantly, we were able to demonstrate the “targetable” nature of these antigens for homing antibodies injected i.v. Functionally, TGFBI showed an additional potential to target the tumor via it’s ability to affect migration and growth of cancer cells, hence taking the influence on the process of tumorigenesis. In conclusion, liver metastases display a significant heterogeneity in terms of targetable biomarkers and these findings should flow in the future development of targeted therapies aiming to cure the patient.

Nowadays, polymer micelles have attracted an increasing interest in pharmaceutical research because they could be used as efficient drug delivery systems. Micelles of amphiphilic block copolymers are supramolecular core-shell type assemblies of several tens of nanometers in diameter. In principle, the micelle core is usually constructed with biodegradable hydrophobic polymers such as aliphatic polyesters, e.g. poly(ε-caprolactone) (PCL), which serves as a reservoir for the incorporation of various lipophilic drugs. Water soluble poly(ethylene oxide) (PEO) is most frequently used to build the micelle corona because it is very efficient in preventing protein adsorption at surfaces and in stabilizing micelles in the blood compartment, making particles invisible to the body defense system. Even if micelles get a high stability in aqueous media thanks to their low critical micellar concentration, micelle dissociation is not always preserved when they are injected in the blood compartment. A way to provide the micelle stability during their administration is to cross-link them. Different kinds of cross-linked micelles can be investigated depending on the localization of the cross-linking. Shell cross-linked micelles or nanocage structures with a degradable core have the great advantage to reach drug encapsulation with a high loading rate. However, cross-linking the hydrophilic shell may affect the stealthiness of the carrier. Thus, we have designed reversibly cross-linked micelles by introducing the cross-linking bridges in the hydrophobic segment of the block copolymer, rather than in the hydrophilic one, leading so to more internal cross-linking and thus preserving the mobility of the hydrophilic segment. Three different localizations of the cross-linking has been targeted; (i) loose core cross-linking of a core-corona system, (ii) tight core cross-linking of a core-shell-corona system (the shell and the core being both hydrophobic and the corona hydrophilic) and (iii) tight shell cross-linking of a similar core-shell-corona system. To reach this goal, three types of amphiphilic copolymers have been used bearing pendent azide groups in the hydrophobic segment. These copolymers have been obtained by starting the ring-opening polymerization of ε-CL and a functional CL, either as a mixture or sequentially from a poly(ethylene oxide) macroinitiator leading to the three targeted architectures. The azide groups located along the PCL backbone have then been used to cross-link the micelles by the Huisgens cycloaddition with a bis-alkyne cross-linker. The choice of this cross-linker has also taken into account the requirement to make the cross-linking reversible. For that purpose, disulfide bridges have been selected in order to impart reversibility to the cross-linking by intracellular reduction. Indeed, the marked concentration difference of glutathione between extra- and intra-cellular environments has already been used to trigger drug release by intracellular disulfide bond cleavage. Accordingly, a bis-alkyne disulfide molecule has been chosen as cross-linker. The micellization and cross-linking of these amphiphilic azido macromolecules have been studied. The reversibility of the cross-linking in reductive environment and the cross-linked micelles stealthiness have been tested. [less ▲]

The replacement and building of new electrical power lines (50 000 km in Europe) can’t cope with the growth of RES development in EU for the ten upcoming years. New solutions have to be found to manage such power transmission needs. Dynamic Line Rating (DLR) systems are part of the global solution. They allow to increase the power line capacity by an average 20% over the static rating (which is defined as the maximum current-carrying capacity as designed). The ampacity or thermal rating, is calculated thanks to (i) sensors installed directly on the power line conductors, like Ampacimon, (ii) weather data, and (iii) standard thermal models (IEEE, CIGRE). However, in order to be fully effective and to allow an efficient use of assets, ampacity calculation in real-time is not enough; it has to be forecasted as well. Beyond 6h-forecast, weather forecasts are necessary to compute the line ampacity up to two days ahead, as needed by network operation. As wind convection has a major impact on conductor cooling, even low wind speeds (2m/s up to 5m/s) allow a huge ampacity increase (the actual rating can be doubled). Therefore, low wind speed forecast up to 2-days ahead finds a major application in dynamic rating of overhead transmission and distribution lines. [less ▲]

Ce papier a pour objectif de réaliser une revue de littérature qui doit permettre de construire une recherche empirique visant à apporter une vision comparative des carrières des hommes et des femmes cadres en regard de trois groupes d’âge : les moins de 35 ans, les [35-50] ans et les plus de 50 ans. Nous considérons les deux sexes étant donné que les trajectoires professionnelles sont influencées par le sexe de la personne ainsi que par les stéréotypes et les rôles qui y sont directement associés (genre). Les générations, quant à elles, nous permettront de tenir compte de l’évolution des facteurs de contexte que sont notamment ces rôles attribués au masculin et au féminin à travers les époques. En effet, les constructions sociales liées au sexe des individus sont susceptibles de changer d’une génération à l’autre et donc d’agir distinctement sur les intentions de carrière. Le fait d’introduire la dimension générationnelle, en plus de celle du genre, est l’occasion d’aborder le concept d’intersectionnalité qui consiste en un croisement des groupes cibles propres à la gestion de la diversité. A l’issue de cet aperçu théorique faisant état de la littérature existante relative à cette thématique des carrières des individus occupant un poste à responsabilités, nous pourrons mettre en évidence différentes questions de recherche qu’il nous faudra, dans un second temps, confronter à la réalité du terrain.

We analyze the behavior of the CO2+ and CO Cameron ultraviolet dayglow in the atmosphere of Mars through a large dataset of dayside grazing limb observations performed by the Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars (SPICAM) on board the Mars Express spacecraft. Limb profiles are studied to retrieve the temperature of the Martian exosphere and its variability with season, latitude and solar activity. We use a one-dimensional chemical-diffusive model to retrieve the main features of the emissions and constrain the temperature and density vertical profiles of the main components of the Martian atmosphere.

The aim of this study is to investigate the mechanochemical behavior of homopolypeptides able to change their conformation is a stimuli-responsive way. The peptidic secondary structures were studied in detail by atomic force microscopy (AFM) at the single-molecule level. Synthetic copolymers containing a polypeptide block were prepared by N-carboxyanhydride amino acid ring-opening polymerization. The polymer chains were grafted as a dilute brush onto gold surfaces and their mechanochemical behavior was then studied by AFM single-molecule force spectroscopy (SMFS). The investigated polypeptide blocks were based on poly(L-glutamic acid), which undergoes a transition from alpha-helix to random coil. This can be induced by external stimuli (pH, ionic strength, temperature) or simply by applying a force. We were able to study the mechanically driven unfolding of the peptide by stretching-release cycles of the biomacromolecule. Stretching the helical peptide resulted in original features in the force-distance traces. Plateaus that are specific for the helical conformation were detected, quantified and discussed. Pulling-relaxing SMFS experiments will eventually lead to a better understanding of the force-induced unfolding of an alpha-helix and the reversibility of the phenomenon. [less ▲]

Waste is considered as a major concern of our century. New technologies and attempts to improve appeared through years. The goal of this study was to evaluate the improvement of waste management through the last forty years. Four steps of time and of technologies of waste treatment were evaluated in an environmental point of view using the life cycle assessment methodology. The first scenario is situated before 1970 with waste landfilling in an open dump without recuperation and valorization of gas. The second one considers the situation between 1990 and 2008 with a plant comprising grinding and sorting of waste to obtain refused derived fuel fraction (RDF) which was burnt in an incinerator, remaining waste being sent to sanitary landfill with recuperation and valorization of gas in electricity. The third one is the current one, in operation since 2009, with incineration of the whole of the residual municipal waste. The last scenario is about future considering the current installation and adding a biomethanation plant using the collected biodegradable fraction of household waste. This environmental evaluation was performed in accordance with the ISO standards 14040 and 14044 and the environmental impacts were calculated with the ReCiPe methodology. We modeled a specific plant situated in Liege using its technical and environmental reports to be as realistic as possible. Main result of this study is the improvement through years starting from the important environmental impact for the landfilling of waste in an open dump to an environmental gain for some categories with the current installation coupled with biomethanation. Global warming impact from the eighties was reduced by 9 in the years 1990-2008 and by 14 for the current scenario alone or coupled with a biomethanation plant. Some sensitivity analyses were used to evaluate the strength of assumptions with for example using a consequential LCA instead of an attributional one and modifying the electricity origin mix. An uncertainty analysis using Monte-Carlo method showed the robustness of our results. This study confirms the environmental improvement of technologies and emissions of waste management through years. [less ▲]

During the last decade, our knowledge of the taxonomic diversity of the Early Cretaceous ichthyosaurs (Mesozoic marine reptiles) has increased significantly, with the recognition of new species, genera, and subfamilies from Canada, Europe, and Russia. New data from England, France, and western Russia suggest ichthyosaurs remained diverse and abundant in western Eurasian marine ecosystems up to the late Albian–early Cenomanian, with the co-occurrence of three to four taxa occupying two to three distinct ecological niches in each formation considered (Cambridge Greensand Member, England; Marnes Bleues Formation, France; Stoïlensky quarry, Russia). However, the overlying formations (middle–late Cenomanian), consisting of chalk or glauconiferous sands, have yielded a very depauperate ichthyosaur fauna. These ichthyosaur assemblages are monospecific and comprise medium to large-sized, presumably opportunistic predators belonging the genus Platypterygius. This suggests a severe drop in ichthyosaur diversity some 5 millions years before their final extinction, which presumably occurred at or near the Cenomanian–Turonian boundary. However, it is difficult to know if this pattern is biased or genuine: the diversity drop may very well be an effect of preservational/ecological biases as well as a genuine extinction linked to the profound environmental changes occurring during the Cenomanian. The presence of similar impoverished assemblages in Cenomanian sediments worldwide favours the latter hypothesis, but the question remains open for now. [less ▲]
