Plants belonging Dacryodes and lrvingia genus have great economic importance in Central and West Africa. lrvingia gabonensis (IG) produces a seed rich in fats, traditionally used as a soup thickener. Fruit of Dacryodes edulis (DS) contains a pulp how are also rich in fat. Its seed constitute a big waste problem in towns and village remains not exploitable by local people however that may be valued as a resource for various components. Some study shows that this seed contented a proportion of oils that would be an alternative in the substitution of diesel relevant to their physicochemical properties. Despite the potential of two different oils, theirs scientific data still lack. In this work, thermo-physical behaviour of those two oils is compared in the aim to improving knowledge about properties of those oils that will promote their valorisation in industry scale. The result of this investigation showed that IGO have a highest proportion of oil content with 72.38% compared to DSO (14.64%). IGO is rich in myristic (49.8%) and lauric fatty acid (37%) but DSO sample was found to possess a higher proportion of linoleic acid (35.13%), palmitic (32.67%), oleic (17.70%) but lower proportion of stearic (9.97%). SFC of IGO was the highest at all temperatures. IGO is solid at room temperature with a complete melting at 40°C but DSO is liquid at room temperature. The polymorphism profile of IGO and DSO shows the 13' form stable during heating and a transition to liquid state without passage at β form. [less ▲]

Milk is a natural complex system present as oil in water emulsion. The natural organisation of milk fat globules is stabilized by the presence of a natural membrane, called the milk fat globule membrane. It has tripartite structure consisting of a monolayer facing the inner triacylglycerol core and an external bilayer. Apart from giving the nutritive value, milk fat globule membrane also contributes towards the techno-functional properties of the dairy products. The milk fat globule membrane is composed of both polar lipids and proteins. Cholesterol is also present in milk fat globule membrane and accounts for about 2% of milk fat globule membrane. Increased consumer awareness has created a perceived demand for low cholesterol products. The World Health Organization and American Heart Association has also recommended that consumers reduce their consumption of saturated fatty acids and cholesterol to lower the risk of coronary heart disease. Therefore, many researchers have developed different methods for reducing cholesterol in dairy and food products. These methods include physical process (vacuum steam distillation, short path molecular distillation and supercritical fluid extraction), biological process (cholesterol reductase and cholesterol oxidase), complexation method (adsorption with saponin, digitonin and cyclodextrin) and chemical process. Most of these methods are very efficient in process of cholesterol removal. However, most of these methods have various drawbacks for application in dairy industry like, formation of toxic oxidation products, denaturation of proteins, loss of low molecular weight triglycerides, loss of volatile components, loss of flavour compounds etc. This leads to loss of nutritive value of dairy products. Thus, the objectives of cholesterol removal from milk and milk products should be, firstly focusing on the maximum cholesterol removal, secondly maintaining the nutritional quality comparable to the control and thirdly the process of cholesterol removal should not compromise the techno functional properties of the dairy products.

Le blé est constitué de trois régions : l’albumen, les enveloppes et le germe. Le blé sert depuis longtemps de nourriture de base à l’homme pour donner, après mouture, à la farine dans le cas des blés tendres, ou à la semoule dans le cas des blés durs. Le produit obtenu correspond à la majorité de l’albumen. Le son de blé est quant à lui un coproduit de cette transformation. C’est un empilement de différents tissus : péricarpe externe et interne, testa, épiderme et aleurone. Actuellement, la valorisation du son de blé reste faible malgré son potentiel nutritionnel. Or ce potentiel permettrait un développement d’additifs alimentaires à haute valeur ajoutée si un fractionnement correct suivi d’une analyse histochimique complète des factions obtenues pouvait être réalisés. Parmi les méthodes de fractionnement, note choix s’est porté sur le debranning qui se base sur le retrait séquentiel des différentes couches extérieures du blé (voir la communication « Mise au point du fractionnement par debranning des tissus périphériques du blé tendre (Triticum aestivum) et du blé dur (Triticum durum) ». Afin de quantifier l’efficacité du fractionnement, l’investigation de la répartition des tissus au sein des fractions produites a été réalisée par l’étude macroscopique (visuelle) et microscopique (coloration histologique spécifique) des grains et des fractions. Un modèle mathématique qui permet l’appréciation de la distribution des couches dans les différentes fractions a également été développé sur base des bio-marqueurs et de la composition biochimique des fractions. L’étude visuelle macroscopique montre que les grains dans tous les cas attaqués de façon hétérogène et ce en raison de la géométrie particulière des grains de blé. L’étude histologique microscopique montre que, malgré cela, certaines fractions sont enrichies en tissus particuliers. Donc, quelque soit la variété étudiée, les fractions obtenues par debranning présenteront toujours une hétérogénéité de composition tissulaire. Après étude du profil nutritionnel (analyse composition chimique), la variété Karim semble la plus intéressante, car elle est riche en protéines, lipides et minéraux. Au niveau des fractions, pour toutes les variétés, la fraction F1 présente le meilleur potentiel. [less ▲]

In a previous study the thermal and polymorphic behavior of four different industrial lauric fats which are sold under the same commercial description, was compared (1). According to the findings the four fats were split in two groups based on the similarities found at polymorphic level. In the present paper two of these industrial lauric fats (F1 and F2, one from each group) were incorporated into oil -in -water emulsions. The objective of this study was to point out the differences in the crystallization and polymorphic behavior between bulk and emulsified fat. Moreover anhydrous milk fat (AMF) was used in the same way for comparison. For that purpose, the fats were investigated for their thermal and polymorphic behavior by differential scanning calorimetry (DSC) and X-ray diffraction (XRD), both in bulk and emulsified state. The DSC and X -Ray investigations made possible the observation of the differences in the crystallization behavior and kinetics that occurred for those fats in the bulk and emulsified state. 1.

Dietary lipids are incorporated in food products under different types of structures, e.g., as dispersed lipid droplets (in oil -in -water emulsions, like creams) or as a continuous lipid phase (in water -in -oil emulsions, like butter for example). The crystallization, melting behavior and polymorphic stability of fats are determined by the behavior of the TAGs they contain. In clinical studies, there is a need to add some 13C TAGs as tracers to the ingested fats in order to track their metabolic fate. However, this procedure could modify the physicochemical properties of the fat. The present study was conducted in the framework of a clinical trial aiming at highlighting the effect of the physical structure of a fat (droplets in 0/W emulsion or bulk) in a meal on the absorption, chylomicron transport and further metabolic handling of dietary fatty acids (1). We therefore monitored the thermal and polymorphic behavior of anhydrous milk fat (AMF) enriched in tracers (a mixture of tripalmitin, triolein and tricaprylin; at 2 different concentrations: 1.5 and 5.7 wt%) using DSC and XRD and further compared it to the native AMF. The addition of 13C TAGs modified the AMF melting profile, especially at high concentration. The enriched AMF was completely melted at around 37°C, i.e. close to the body temperature. However, under some conditions, the AMF enriched in high 13C TAGs concentration remained crystallized at 37°C. Similar trends were observed in both systems (bulk vs emulsified). Moreover, AMF polymorphic behavior was also modified upon tracer addition. While only β’ form was observed in the native AMF, the 13 -form was detected in the AMF containing high 13C TAGs concentration. Importantly, low concentration of tracers should not have high impact on human digestive physiology. However more attention should be paid to physicochemical structure when high concentrations are added. (1) Vors et al. 2013.

Le 22 décembre 1645, l’internonce en poste à Bruxelles, Antonio Bichi, donne l’absolution à Charles IV de Lorraine . La sentence prononcée par l’envoyé pontifical doit mettre fin à plus de trois années de tensions qui font suite à la bulle d’excommunication fulminée par le pape Urbain VIII à l’encontre du duc. Pour le Saint-Siège l’enjeu diplomatique de ce geste est grand. Charles IV, duc de Lorraine et de Bar, est en effet un membre important du parti des dévots, hostile à Richelieu et à sa politique d’abaissement de la maison d’Autriche. Réfugié aux Pays-Bas depuis l’occupation de ses états par le cardinal, en 1634, il prend part aux dernières phases de la guerre de Trente Ans en mettant ses troupes au service des Habsbourg, aussi bien en France que dans l’Empire. Or, l’excommunication du duc comme la mauvaise volonté dont celui-ci semble faire preuve pour répondre aux exigences de la Curie romaine ont peu à peu créé des dissensions au sein du clergé et du gouvernement des Pays-Bas. L’irritation qui règne menacerait même la bonne conduite de la guerre menée contre la France et ses alliés protestants. Si, à première vue, la papauté ne prend pas une part active dans ce conflit, elle veille naturellement, à travers ses nonces, aux intérêts catholiques qui sont en jeu. J'ai choisi, à l’occasion de ce colloque, d'étudier plus en détail la conduite de l’internonce Bichi dans le retour en grâce de Charles IV et son absolution en 1645. À cette occasion, j'ai voulu dégager, d’une part, les stratégies mises en place par le prélat pour arriver à ses fins (maîtrise de l’information, entreprise de désinformation et de dénigrement du duc,…) et, d’autre part, les acteurs et les réseaux avec lesquels il est en prise lors de ces négociations (gouvernement des Pays-Bas espagnols, confesseurs, parti des dévots, ordres religieux, Saint Office,…). Une telle analyse devrait permettre de saisir la nature et l’étendue des ressources que l’internonce utilise afin de mener une véritable politique de détente, propre à réconcilier les intérêts politico-religieux et les intérêts juridico-dogmatiques du Saint-Siège. Je désirerais, par cet exercice apporter une contribution à la compréhension de la politique menée par les nonces du Saint-Siège lors de la fin de la guerre de Trente Ans et à l’occasion des Congrès de Westphalie ; moments diplomatiques habituellement considérés par l’historiographie comme étant défavorables à la papauté.

Cette communication vise à étudier la participation des femmes migrantes marocaines à la vie sociale du « pays d’accueil » ; participation qui se réalise grâce aux activités de la vie quotidienne. En particulier, la performance publique des pratiques culinaires, observée dans une ville de la province de Milan, permet aux femmes considérées d’exercer une agency à l’intérieur des espaces institutionnellement concédés à l’expression des migrants. D’un côté, la consommation des « recettes de l’Autre » de la part de la population majoritaire détermine une incorporation de la diversité afin de la contrôler. De l’autre côté, la préparation de ces recettes consent aux migrantes d’exprimer leur subjectivité (individuelle et collective) de façon active et en présentant des aspects qui vont au-delà de la culture alimentaire. Une participation sociale fondée sur le partage de nourriture donne la possibilité aux femmes d’assumer un rôle actif dans la communauté locale, tout en affirmant ses propres spécificités. Des sujets tels que la liberté religieuse sont abordés, et certains droits peuvent être réclamés par des individus qui ont ainsi acquis une position politiquement importante au sein de la société locale.

La chirurgie en cas de maladie de la Peyronie sans implant pénien peut être décevante. Il faut imaginer avec le patient, avant l’opération, la taille de la verge et la qualité de l’érection après la chirurgie de redressement.Si ces estimations risquent de conduire à une insatisfaction, l’implant pénien est une solution efficace permettant rigidité, rectitude et optimisation de la longueur de la verge. Globalement, en cas de maladie de la Peyronie et d'implant pénien, la satisfaction du patient et du couple est élevée et la durée de vie de l’implant n’est pas inférieure à celle des prothèses implantées dans des verges non déformées. Le risque global lié à l’implant est superposable aussi (sauf en cas de greffe majeure) La verge fortement raccourcie par la maladie est une bonne indication d’implantation avec des risques légèrement majorés.

Afin de maximiser le potentiel de biodiversité d’une carrière en fin d’exploitation deux options s’offrent au gestionnaire : (1) laisser les espèces recoloniser spontanément le site, (2) mettre en œuvre des appuis techniques à la restauration d’écosystèmes. Une méthode hybride associant une recolonisation naturelle et une assistance technique peut également être une opportunité pour le gestionnaire. La recolonisation spontanée des carrières peut, dans certains cas, créer une mosaïque d’habitats diversifiés pour des coûts faibles par rapport à des projets de réhabilitation ou de restauration couteux. Toutefois, l’intérêt biologique des habitats issus de successions spontanées peut fortement varier d’un site à l’autre en fonction de l’historique de gestion, des conditions climatiques et édaphiques locales, de l’isolement du site dans le paysage et du pool régional d’espèces présentes. Afin d’évaluer la nécessité ou non de mise en œuvre d’une restauration active d’habitats en carrière, il est nécessaire de caractériser les habitats issus de la succession spontanée ainsi que leur valeur biologique. L’évaluation de l’intérêt biologique d’un habitat prend en compte à la fois la diversité biologique locale (diversité alpha) et l’originalité des communautés présentes par rapport à un référentiel paysager (diversité béta). Ce projet a pour objectif de caractériser la flore recolonisant spontanément les zones xériques non exploitées dans une carrière située en Belgique (Loën, en région wallonne), du point de vue de la diversité spécifique et de la fonctionnalité écologique. Les communautés végétales ont été caractérisées au sein du site de Loën (diversité alpha) et d’un ensemble d’autres carrières représentatives de la diversité des contextes géographiques des carrières calcaires en Région wallonne (diversité béta).

The last part of SpS5 dealt with the circumstellar environment. Structures are indeed found around several types of massive stars, such as blue and red supergiants, as well as WRs and LBVs. As shown in the last years, the potential of IR for their study is twofold: first, IR can help discover many previously unknown nebulae, leading to the identification of new massive stars as their progenitors; second, IR can help characterize the nebular features. Current and new IR facilities thus pave the way to a better understanding of the feedback from massive stars. [less ▲]

Most recent SAR sensors use wide band signals to achieve metric range resolution. One can also take advantage of wide band to split it into sub-bands and generate several lower-resolution images, centered on slightly different frequencies, from a single acquisition. This process, named Multi Chromatic Analysis (MCA) corresponds to performing a spectral analysis of SAR images. Split-Band SAR interferometry (SBInSAR) is based on spectral analysis performed on each image of an InSAR pair, yielding a stack of sub-band interferograms. Scatterers keeping a coherent behaviour in each sub-band interferogram show a phase that varies linearly with the carrier frequency, the slope being proportional to the absolute optical path difference. This potentially solves the problems of phase unwrapping on a pixel-per-pixel basis. In this paper, we present an SBInSAR processor and its application using TanDEM-X data over the Nyiragongo volcano. [less ▲]

With the underlying hypothesis of a shift toward neoliberal science regimes, much work has been done to analyze the multiple transformations of science institutions and policies over the last decades (e.g. Mirowski and Sent 2008; Slaughter & Rhoades, 2004; Bruno, 2008). The trends towards privatization and commodification of science are undisputable but we argue that little attention has been paid so far to the various political conceptions of research and innovation (R&I) coexisting within neoliberal science regimes. Cognitive approaches to public policy already stressed the circular relationship between meaning and power (e.g. Muller and Surel, 1998; Roe, 1994), but neoliberal science has remained out of the scope of such analyses. Regarding R&I policies, this leads to different ways to conceive of the “value” of science, some related to preexisting institutions and narratives, and some branching out toward new cognitive resources to achieve politico-economic aims. In our proposal, we hypothesize the coexistence of at least four policy narratives which help structuring the representations and actions of scientists and policymakers when they address science as a political object: ‘science for the sake of science’, ‘science, the endless frontier (continued)’, ‘knowledge-based economy’ and ‘grand societal challenges’. Each one attributes a different value to science, proposes a specific organization for the R&I system, and addresses the relation between economy and society differently. In order to understand how these policy narratives are locally articulated, and thereby grounded in R&I policymaking, we analyze the political discourses on science at three different institutional levels (biotechnology labs, university management, science policy advisory boards) in Belgium. Our data were gathered through semi-structured interviews with key members of the institutions studied. By analyzing the interplay of policy narratives for R&I in a context of neoliberal science, we aim to contribute to a better understanding of the ways science is valued at different levels. [less ▲]

In the Congo Basin forests, local communities used to live from hunting, fishing and gathering, and from slash and burn agriculture. Nowadays, few places remain isolated from the external world, and local practices often have to integrate new parameters. How do family farming and forest activities evolve in a changing landscape, when forest disappears? To answer this question we selected three social and ecological systems positioned in specific places on the forest transition curve (Mather 1992), to constitute a synchronic sample of forested social and ecological system representative of the evolution of Congo Basin Forests. We conducted in 2013 and 2014 a deep analysis of family farming in 8 villages distributed in these 3 studied sites. The method crosses a systemic approach with a systematic approach: agrarian diagnoses were conducted in the three sites (Boulaud 2014; Ferlay 2014) to evaluate technical and economic performances of family farming and forest extractive activities, in parallel, census of households were conducted (Codina Llavinia 2014; Gillet et al. 2014; Lehnebach 2014) to range family activities according to their share in the family income and as subsistence means. Results were harmonized and allowed a deep understanding of the strategy of adaptation to changes of households. [less ▲]

Background: Mesenchymal stromal cells (MSC) are multipotent bone marrow progenitors that have demonstrated significant immunosuppressive effects in various in vivo and in vitro studies. This study aimed to be the first evaluation of the safety and tolerability of MSC infusion after liver transplantation in a prospective, controlled phase-1 study. This study aimed to be the first evaluation of the safety and tolerability of MSC infusion after liver transplantation in a prospective, controlled phase-1 study. Patients & Methods: Clinical grade MSCs were locally collected from the bone marrow of unrelated healthy donors. They were cultured in a GMP-compliant lab, underwent extensive quality controls and were frozen for storage in a MSC bank. When needed for patient treatment, MSC were thawed and intravenously injected into patients. 10 liver transplant recipients under standard immunosuppression (TAC-MMF-low dose steroids until day 30) received 1.5-3x106/kg MSC on post-operative day 3±2. These patients were prospectively compared to a group of 10 control (MSC-) liver recipients. Primary endpoints were MSC infusion toxicity, and incidence of cancer and opportunistic infections at month 6. Secondary endpoints were patient and graft survivals and rejection at month 6, as well as the effects of MSC on recipients’ immune function and on immunohistology of at month 6 graft biopsies. Results: No MSC infusional toxicity was observed. Both groups were comparable in terms of donor and recipient characteristics. There was no difference in primary end-points between control and MSC groups. No patient developed de novo cancer. There was no statistical difference in patient and graft survivals or in rejection rates. There was no graft rejection in the MSC group. Month-6 graft biopsies were not different according to Banff and fibrosis scores. Discussion: This phase 1 study showed excellent tolerability and safety of a single infusion of third-party MSC after liver transplantation. There were no graft safety issues and no excess of immunosuppression after MSC injection. Further analyses of consequences of MSC injection on the immune profile are needed. The possibility of avoiding calcineurin-inhibitors with repeated MSC injections as main immunosuppressive therapy and/of tolerance induction by MSC infusion should be investigated by further studies.

Both in Europe and in the United States, scientific research and science, technology and innovation (STI) policies have undergone profound changes in the last thirty years. In the literature, these transitions are often framed along dichotomous lines : an 'old regime' characterized by strong public funding, independent academia and a linear conception of innovation has supposedly been replaced by a 'new regime' in which research and innovation are conceived in systemic terms, regarding their economic and societal relevance (Rip 2000). These conceptions have been criticized regarding their historical accuracy, or regarding their (un)political-reading of those evolutions (Pestre, 2003). More broadly, Nowotny has recently emphasized the fact that the political understanding of science has been black boxed in STS (Nowotny, 2014). My proposal aims at investigating the multiple political conceptions of science in a regional context: what value is attributed to science? What are its aims? How should it be organized and funded? More specifically, this paper relies on an analytical framework based on the notion of "policy narratives" for science to examine how coexisting, and sometimes competing narratives are embedded in situated discourses, policies and practices. Policy narratives include the following elements (Jones & McBeth, 2010): A context, a plot (a sequence with a beginning, a middle and an expected end: Roe, 1992), characters that have a role and intervene in the plot, and some kind of 'moral' of the story advanced as a policy solution. As narratives help actors to make sense of things and orient their actions, they are both descriptive and performative. Hence, they relate to the notion of imaginary in a very concrete sense: narrative are related to actual institutions, and emerging policy narrative can serve as rationale for change. In this paper, narratives like, e.g., the "Knowledge-based Economy", the "Grand societal Challenges", "Science, the endless Frontier", are studied. Each attribute a different public value to science: improving economic growth, tackling specific issues such as cancer or ageing population, or increasing knowledge as a good in itself. Each also propose a specific organization for the STI system, and assign a specific role to the various stakeholders (the scientists, the university authorities, policy makers, industrialists and entrepreneurs, etc.). In order to understand how these global policy narrative are locally articulated, and thereby grounded in regional STI policymaking, my research is based on interviews with a range of stakeholders in Wallonia: biotech lab leaders, members of university boards, and representatives of labor and employers' organizations in regional advisory boards. In the analysis, a particular attention is paid to the various narratives used by the stakeholders when answering broad questions, with regards to their position. More specifically, the way stakeholders depict and scenarize their own role(s) and their relations with other actors is highly political and hence should be assessed. A main thesis of the paper is that one narrative does not constitute the only resource of a (group of) actor(s). Actors refer to different narratives regarding the context and regarding the evolution they promote. [less ▲]

Plant protection strategies are strongly focused today on the development of alternative methods in order to complete or replace conventional chemical inputs. Elicitors of biological origin are increasingly considered as a promising tool as biocontrol agents. They offer the possibility, through the induction of plant natural defences, to preventively protect plants against a large spectra of diseases. Multiple elicitors have already been identified since their first discovery in the late 70s, but few research has been focused on crop pathogens although such diseases can strongly impact both yield and grain quality. We describe hereby a method of elicitor screening to protect wheat against Zymoseptoria tritici. Focus is made on the importance of a good disease infection protocol in order to achieve screening tests. [less ▲]

What are the similarities and differences between the behavior of a small vibrating test system and an F-16 fighter? To find it out, we compare measurements of the test system to measurements from the bolted connection of the wing and the missile of a F-16 Fighter Falcon from the Belgian air force. These measurements were done during a ground vibration test (GVT) campaign. Essentially, the behavior of these systems match, even though the test system is only the heart of a self-study kit for nonlinear system identification and the F-16 is a complex real life mechanical structure. This clearly shows the added value of an experiment driven nonlinear educational system identification package. It provides safe small-scale toy examples for hands-on exercises that react like real systems. We believe that this practical approach lowers the gap between learning system identification concepts and applying it on real systems. [less ▲]

In the present contribution, it is shown that, in the case of mechanical systems where nonlinearities are physically localised, the general structure of black-box nonlinear state-space models can be drastically simplified. A more parsimonious, grey-box state-space representation is derived, which is found to be compatible with Newton's second law of dynamics. For demonstration purposes, black-box and grey-box state-space models of the Silverbox benchmark, i.e. an electrical mimicry of a single-degree-of-freedom mechanical system with cubic nonlinearity, are identified using a maximum likelihood estimator. It is found that the grey-box approach allows to reduce markedly modelling errors with respect to a black-box model with a comparable number of parameters. It is also suggested that the greater accuracy of the grey-box model lends itself to the computation of reliable confidence bounds on the model parameters. [less ▲]

Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia, and in particular during multitasking activities (Semkovska et al., 2010). Multitasking refers to activities (e.g. preparing a meal) where the person has to: (a) carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; (b) define the tasks’ targets; (c) and where the person is faced with unexpected problems during the realization of these tasks (Burgess, 2000). However, the cognitive underpinnings of multitasking abilities have never been adequately explored in schizophrenia. Further, only two cognitive models exist in the literature, which are based on student (Logie et al., 2011) and neurological (Burgess et al., 2000) samples. Both of these models suggest three primary constructs: Memory, Planning and Intent. There are, however, several limitations related to the way multitasking abilities were evaluated in these studies. We thus developed a computerized real-life activity task - the Computerized Meeting Preparation Task (CPMT), which was specifically designed to take into account the multitasking nature of certain everyday life activities. Using this task, and based on previous studies (Burgess et al., 2000; Logie et al., 2011), the aim of the present study was to evaluate multitasking abilities in schizophrenia and to do so in a new cognitive model of multitasking that takes into account certain cognitive functions that are not integrated in existing models. Methods: Fifty-seven individuals with schizophrenia and 41 matched healthy controls completed the CMPT. Participants were also evaluated with a battery of cognitive tests. Results: The results suggest that the CMPT possesses good sensitivity and confirmed the three underlying constructs of multitasking (Memory, Planning and Intent), which were found to be underpinned by several cognitive functions and multitasking aspects. Conclusion: Taken together, this new cognitive model and the CMPT could be a good basis for cognitive interventions of multitasking abilities in schizophrenia. Burgess, P.W., 2000.

Physical processes are known to play major roles in marine plankton succession. However, few studies have addressed the mechanisms that regulate phyto- and zooplankton phenology in a context of changing climate. Here we used a unique long-term (1979-2011) time series performed in a Mediterranean coastal area unbiased by local anthropogenic pressure (PHYTOCLY station, Bay of Calvi, Corsica) to understand how environmental forcing affects the timing, duration and magnitude of the winter-spring phyto- and zooplankton blooms. We showed that phyto- and zooplankton blooms were bottom-up controlled by the establishment of favourable abiotic conditions, i.e. nutrient replenishment by vertical mixing under specific water temperature and wind conditions, for which thresholds were defined. According to the intensity of winter characteristics, there were strong differences in both the abundance and composition of phyto- and zooplankton during the winter-spring period. Our study is consistent with the recent reports that, when occurring, diatoms peaks were added to the initial phytoplankton groups instead of replacing them. In contrast, zooplankton groups followed a replacement sequence. Based on the results provided by our time series, we show that plankton phenology in the Bay of Calvi is highly controlled by climate variation and exhibits contrasted patterns in response to different scenarios of environmental forcing.

The consequences of collision events can range from minor structural damages of the supporting structure to complete collapse of the wind turbine, which may lead to disruptions of the electricity production and, at worst, to sinking of the striking ship with probability of loss of human lives or/and pollution. For all these reasons, a collision risk analysis becomes mandatory at the pre-design stage in order to identify the collision scenarios having the greatest probabilities of occurrence, to estimate the consequences of collision events and to ensure safe operations through the wind farm service life. The goal of this paper is to outline the behavior of the monopile foundations during ship collision by performing non-linear finite element simulations. Many collision scenarios are analyzed in order to study the sensitivity of the monopile to various parameters like impact striking ship velocity, nacelle mass, wind direction, soil stiffness, vertical location of the impact point, wind orientation … The internal energy dissipated by deformation of the monopile, the crushing force and the indentation of the crushed area are compared for different situations, as well as the overall displacements of the supporting structure.

The purpose of the present study was to explore the ability of neglect patients to detect and exploit the predictive value of a cue to respond more quickly and accurately to targets on their contralesional side in a Posner spatial cueing task. The majority of the cues (i.e. 80%) were invalid, indicating that the target would appear on the opposite side, although patients were not informed of this bias. Our results demonstrate that some neglect patients were able to extract the cue’s predictability and use it to orient faster toward the left. This cueing effect was present even in patients who were subsequently unable to describe the predictive character of the cues, and thus was not modulated by reportable awareness of the cue-target relation.

In Belgium, Nuclear Waste Management (NWM) is conducted by a Federal Agency called ONDRAF - i.e. the “National Agency for Radioactive Waste and Enriched Fissile Materials”. Adhering to a largely accepted vision, NWM is considered by ONDRAF as a long-term and complex issue, consisting in technical, social, economic and ethical questions. In this respect, scientific literature invites to clarify and address those aspects in a decision-making process that could benefit from meaningful public participation (Callon, Lascoumes, and Barthes 2001). In this context, many stakeholders (e.g. citizens, researchers, industrialists, civil society organizations, the European Union... and ONDRAF itself) are in demand of a “conductor” that can organize, ensure and legitimize such a participatory decision-making process. Many questions emerge from this demand. Who can be the gatekeeper of this process? What could be his role? For which purposes? In addition to that, how should participation be organized/assessed/controlled? To that regard, the purpose of this paper is twofold. First, I elaborate a possible definition of “gatekeeping a participatory decision-making process concerning NWM in Belgium”. Second, I question the possible role of Technology Assessment (TA) - as an institution as well as a set of approached - in this context. To address those questions, I rely on a combination of theoretical and empirical materials – i.e. semi directive interviews with policy makers and members of Belgian and French agencies in charge of NWM.

Introduction and objectives: Colorectal cancer (CRC) is the second most frequent cancer in women and the third in men. Identification of the mechanisms of progression in these early CRC stages is important to develop new diagnostic and therapeutic tools. Formalin-Fixed Paraffin-Embedded (FFPE) specimens are materials that enable proteomic clinical research. Hence our aim was to address the comparison of FFPE samples from early CRC stages patients using shotgun proteomic analysis. Methods: We performed a retrospective study on 36 CRC tissue samples (pT1N0M0, n=16 and pT2N0M0, n=20) compared together and with 40 control tissue samples (20 patients with diverticulitis, using paired inflamed (DI) and healthy tissue (DH)). Each tissue slice was macrodissected to enrich in epithelial cells. We used FFPE-FASP kit (Expedeon) for sample preparation and protein digests were analyzed using 2D-nanoAquity UPLC separation online with Q-Tof Synapt HDMSTM G2 using ion mobility as additional separation. We performed protein identification and differential analysis using Progenesis QI for proteomics (Nonlinear Dynamics). Results and discussion: We selected 149 proteins differentially distributed between T1 and T2 CRC stages which were not significantly different between CRC and DH or DI. Only 30 proteins were significantly more abundant in T1 versus T2 and 119 were distributed inversely, with a minimum fold ratio of 2. Among those, ATP synthase subunit beta, Aspartate-tRNA ligase, Haptoglobin and Kininogen were identified. . Moreover, we validated Kininogen and 3 others proteins with a significant differential distribution between pT1N0M0 and pT2N0M0 stages by immunohistochemistry. Conclusion: This FFPE retrospective study comparing T1 and T2 CRC highlighted proteins already previously identified as potential CRC biomarkers. These proteins may reflect important early changes in cancer development and may help understanding early tumor progression. [less ▲]
