L'école est identifiée comme un des piliers de la lutte contre la sédentarité des jeunes. Une société américaine (HOPSports) conçoit et diffuse des séquences de quelques minutes qui mettent en scène des personnages, réalisant des activités à imiter en classe: les 'Brain Breaks' (BB). Ces videos ont été proposées pendant trois mois dans deux écoles primaires de la région liégeoise. L'opinion des élèves est positive mais leurs attitudes à l'égard de l'école et de l'activité physique ne change guère. [less ▲]

Eggs are a rich source of lipids and proteins. Because of their low production cost, they represent a cheap source of animal proteins and lipids. recently, in Algeria, consumers’ interest are oriented of healthiness and dietetic values food. The purpose of this study was to investigate the effects a dietary supplement of Urtica dioica on laying hen's performance and egg quality. The study was conducted from may to june 2014 in the area of Chemini (Algeria). Sixty, 25-wk-old Lohmann Brown layers were randomly divided into 3 groups with 20 hens in each group. Group 1 was the control group fed a standard commercial diet based on corn and soybean, whereas the groups 2 and 3 were fed the control diet supplemented with 1% and 1.5% of nettle respectively. The hens were housed in cages in the same local and fed ad libitum. Fifty five eggs were sampled 4 times in each group from 25 to 27 weeks. A total of 220 eggs were examined. A series of measurements were carried out on each egg, namely egg weight, form index (egg shape), yolk to albumen ratio (Y:A), Yolk color, egg shell thickness, Haugh’s units. Egg weight, yolk color and Haugh Units (HU) were affected by age. Significant differences (P<0.05) were recorded between feeding type in total egg weight, yolk color and Haugh Units. The egg from group 2 proved to have a higher egg weight (57.67g; group 1: 55.41g; group 3: 56.70g; P<0.05), (33.4%), intermediate Yolk color (8.53; group 1: 9.03 ; group 3: 9.38; P<0.05) and HU (79.81; group 1: 80.85; group 3: 76.92). The results showed that the use of 1% and 1.5% of Urtica dioica, had positive effects on the color of yolk of laying hens. Using different levels of Urtica dioica could change the characteristics of egg and could meet the preferences of consumers for the intense color of the yolk. [less ▲]

L’evidence-based practice (EBP) est une approche qui recommande d’optimiser les soins de santé en intégrant les meilleures données actuelles issues de la recherche scientifique, l’expertise des cliniciens ainsi que la situation et les préférences de chaque patient (Sackett et al., 1996). L’EBP fait couler beaucoup d’encre en médecine, où elle prend sa source, mais également dans d’autres disciplines. Certains praticiens ne jurent que par elle, d’autres la décrient… Quoiqu’il en soit, le recours à l’EBP est de plus en plus encouragé en logopédie et en psychologie. Les principaux objectifs de cette conférence seront de définir l’EBP, d’en décrire les étapes et d’exposer les bénéfices et les obstacles à son application. Des perspectives d’avenir seront également discutées afin que l’EBP puisse intégrer le quotidien des logopèdes et des psychologues en Belgique. [less ▲]

Il existe des parentés remarquables entre certaines caractéristiques du roman d’aventures et les premières fictions d’anticipation françaises. Il n'y a pas seulement que la notion d’"aventure" est floue, composant une catégorie infiltrante tenant de l’hypergenre ou du genre parasite, mais il existe aussi des propriétés communes formant un genre hybride de « science-fiction d’aventures» qui compose un corpus important, pourtant peu considéré par les études littéraires consacrées au récit d'anticipation. Envisagé sous cet angle, tout un pan de la production d’anticipation de la seconde moitié du XIXe siècle apparaît comme marqué par le déplacement géographique autant sinon davantage que par le voyage temporel, cultivant une plasticité qui permet dans certains cas des reprises à l’identique ou presque. Ce sont ces procédés d’hybridation qui font l'objet de cette communication, à partir d’un type de récits généralement considéré comme un sous-genre matriciel de l’aventure, la robinsonnade, considérée dans quatre romans du dernier quart du XIXe siècle: André Laurie, Les Exilés de la Terre; Georges Le Faure, Les Robinsons lunaires; Jules Verne, L'Île à hélice; Paul Adam, Lettres de Malaisie.

The objective of this study was to evaluate the effects of the inclusion of Urtica dioica leaves meal in diets on growth performances and carcass characteristics of broiler chicken. The study was conducted from May to June 2014 in the area of Chemini (Algeria). In a completely randomized design, a total of 100 one-day-old broilers (industrial strain) were divided into 2 groups and 2 repetitions with 25 chickens each. Group 1 was the control group fed a standard commercial diet based on corn and soybean purchased on the local market, whereas the birds in group 2 were fed the nettle diet (control diet with addition of 2% of nettle). The animals were housed inside in experimental pens and fed ad libitum. The results showed that nettle inclusion significantly promotes growth performance of broilers at 42 days of age (1644.8 ± 45.5 vs. 1565.1 ± 45.5g; P<0.05). The broilers fed the nettle diet had higher thigh yield (26.0 ± 0.3 vs. 25.2 ± 0.3%; P<0.05) but lower abdominal fat yield (4.39 ± 0.16 vs. 3.90 ± 0.16%; P<0.05). No significant effect of the diet was observed for carcass yield (around 71.1%) and breast percentage (around 32.40%). The overall mortality was not significantly different (P>0.05) for any of the dietary regimens (around 20%). Feed conversion ratio of the two groups were very close (around 2.17). This experiment showed that dietary inclusion of Urtica dioica has positive effects on growth performance and carcass quality of broilers. [less ▲]

The livestock sector plays a dynamic role in the economic development of rural areas in Algeria. Due to its adaptation to harsh environments, goat breeding is practiced in many areas of the country. To the north, it is confined to mountainous areas, but the bulk of the workforce is left in the steppe and semi-desert areas. The goat population in Algeria reached 3.8 million heads, ranking second after sheep. The present work contributes to a better characterisation of local goat in Kabylie for production and reproduction traits. The study was conducted in the regions of Chemini (Bejaia province) and Bouzeguene (Tizi-Ouzou province). A survey was conducted in 29 herds. The results revealed that the overall mean of goats per households was 6.69 ± 2.97. The purposes of keeping goat in Chemini and Bouzguene was private consumption of milk (82.76%) and meat (68.97%) as well as for commercial exchange (62.07%). The Kabyle goat is small (male: 62.23 cm and female: 58.41 cm) with long hair. Its ears are drooping, its convex profile has a slightly pronounced nasal split and its coat colour ranges from dark brown to black. However, the crossbreeding with exotic breeds (mainly with Saanen goat), controlled or uncontrolled, increased the frequency of white coat. The average age at puberty in males was 6.93 ± 1.04 and 7.38 ± 0.94 months in females. The reported age at first kidding and kidding interval were 13.03 ± 0.87 months and 7.83 ± 1.29 months, respectively. [less ▲]

Cet atelier aura pour objectif de présenter un modèle théorique, testé auprès de 500 personnes, des liens entre la dépression, le niveau d’engagement dans des activités et différentes familles de processus psychologiques (image de soi, pensées négatives répétitives, évitement expérientiel, satisfaction environnementale, régulation émotionnelle et tendance à l’approche). Plus précisément, nous menons actuellement une étude dont les résultats nous permettront d’identifier les processus psychologiques médiateurs de la relation entre la dépression et le niveau d’engagement dans des activités. Ces processus psychologiques médiateurs pourront donc devenir des cibles précises et identifiées du traitement psychothérapeutique. Pour mener à bien cette étude, nous avons réalisé une revue de la littérature des outils évaluant spécifiquement ces processus psychologiques. Certains questionnaires ont été traduits de l’Anglais au Français et sont en cours de validation. L’ensemble des échelles utilisées, leur utilité et leur cotation, seront présentées lors de l’atelier. Elles seront également mises à disposition des cliniciens intéressés.

Chlorophyll is a photosynthetic pigment available abundantly in microalgae and terrestrial plants. This pigment found applications in pharmaceutical, cosmetic and food products as a wound healing, antioxidant or coloring agent. Recent reports suggest that chlorophyll can also be used as a biomordant to enhance the dyeing process of textile products, but also as a textile dye with antimicrobial properties. In this presentation, different aspects of chlorophyll production are discussed. Firstly, numerous plant biomass types as potential sources of chlorophyll are presented. Subsequently, different methods for chlorophyll extraction and separation from plant biomass are described. Finally, possibilities of chlorophyll implementation into textile products on industrial scale are evaluated. [less ▲]

Nous avons analysé les dossiers de 1079 patients (754 femmes et 325 hommes) qui se sont présentés au CHU de Liège entre 2009 et 2013 pour une plainte vocale. Chez ces patients, nous avons répertorié 121 personnes sans profession (11%), 166 étudiants (16%), 215 retraités (20%), et 577 travailleurs (53%). Parmi ces 577 travailleurs, il y avait notamment 129 enseignants, 55 employés de bureau, 50 chanteurs, comédiens et musiciens, 41 commerçants, 39 managers, 37 aides ménagères et 35 ouvriers. Objectif : Pour les travailleurs, nous avons tenté d’établir le degré d’exposition aux troubles de la voix selon la profession exercée en fonction de leur représentation dans la partie francophone de la Belgique (Wallonie). Notre objectif était de cibler les travailleurs les plus à risque de consulter un spécialiste de la voix. Méthode : Nous avons estimé la proportion de ces travailleurs par profession en calculant le rapport entre leur nombre en consultation phoniatrique et leur nombre parmi les travailleurs wallons. Résultats : Les travailleurs qui consultent le plus pour un problème de voix et qui sont donc le plus à risque sont, par ordre décroissant : les chanteurs, comédiens et musiciens (3.3% ont consulté), suivis par les professeurs de musique (1.5%), les animateurs (0.45%), les entraineurs sportifs (0.29%), les psychologues (0.20%), les journalistes et standardistes (0.17%), et les enseignants (0.14). En conclusion, cette étude montre que les travailleurs qui consultent le plus en phoniatrie ne représentent pas nécessairement le groupe professionnel le plus à risque. [less ▲]

At the beginning of Meditation IV the meditator triumphantly announces that he has “now no difficulty in turning away (convertam) from imaginable things and toward things which are objects of the intellect alone” (AT, VII, 53). Meditation VI thereafter confirms that pure intellection, as opposed to imagination, consists only in turning towards oneself (convertat) and demands no “peculiar effort of the mind” (73). However efforts of attention are required throughout the Meditations and Meditations IV, V and VI are no exceptions in this respect. Descartes’ Second Set of Replies (156-159) confirms that attention is needed as a mental support for metaphysical analysis in order to embrace different ideas and connect different parts of a demonstration. A thorough examination of the Meditations shows something even more interesting: attention is conceived by Descartes as a varying force that can be diminished or relaxed but also, and most importantly, increased as comparative forms like “attentius” (19; 55; 66; 71) or “diligentius” (32; 35; 45) suggest. For sure, it is an original aspect of Cartesian meditative exercise: we are not only invited to maintain our attention but also to make it more intense at a certain point. Such an increase is crucial for the development of the dream argument (55) and also for the achievement of both proofs of the existence of God (45; 66). But is it not a kind of deus ex machina that the meditator puts forward in order to overcome otherwise unsolvable difficulties? A posterior work, The Passions of the Soul, can help us understand such a strategy. In article 72, Descartes distinguishes between two kinds of attention; the first one stems from wonder and is “at its full strength from the start” (XI, 382); it is contrasted with a second type “which, being weak at first and growing only gradually, can be easily diverted” (Ibid.) Further on Descartes says that passion is useful in “strengthening thoughts… and causing them to endure into the soul” (383) but that “the application of our understanding” has the same effect when “our will fixes [it] in a particular attention or reflection” (384). This last case applies to the Meditations: the meditator who is constantly exposed to misleading influences would be easily “diverted” and even stopped if he was not pushed by his own will to go further in his metaphysical inquiry. “Peaks” of attention occurring in the Meditations are caused by volitions originating in the meditator’s resolution to attain truth and certainty and, as we shall see, they are used against three types of harmful influence: sensitive in Meditation I, imaginative in Meditation II and III, and intellectual in Meditation IV and V where old philosophical habits stand in the way of Cartesian theology.

IS THERE A ROLE FOR INTRA-ARTERIAL THERAPY OR ISOLATED LIVER PERFUSION? Pr Olivier Detry, Dpt of Abdominal Surgery and Transplantation, CHU Liege, University of Liege, The liver is the most common visceral site of colorectal cancer (CRC) metastasis and recurrence. Approximately 25% of CRC patients present with synchronous hepatic metastases at time of initial diagnosis, and further 50% will develop metachronous metastases during the course of their illness. Unfortunately, only 25% of patients with hepatic CRC metastases are suitable for R0 resection at time of diagnosis or after chemotherapy. Intra‐arterial locoregional therapies are evolving tools in the management of CRC liver metastases. Although these therapies were initially used for salvage and palliation, they are becoming therapeutic options earlier in the course of disease in selected populations, to increase the rate of curative surgical resection, and to improve survival and quality of life. Furthermore, intra‐arterial therapies may serve as viable first‐line treatments for the large majority of patients who present with unresectable liver metastases, and as neoadjuvant chemotherapy prior to hepatectomy to minimize systemic effects. Hyperthermic isolated liver perfusion (HILP) has also been proposed by some groups as a mean to treat patients with unresectable liver metastases. Significant anti-tumoral effect has been demonstrated but HILP is a complicated procedure with a high morbidity. There remains a lack of robust, prospective randomized data for fair and balanced comparisons to be made between locoregional and modern systemic therapeutic modalities, as well as between locoregional therapies. Future RCTs addressing overall patient survival, tumor response and toxicity are required before any of these locoregional intra‐arterial treatments can be definitively recommended as the standard of care for hepatic colorectal liver mestastases. At the CHU of Liege, intra-arterial chemotherapy is now the usual way of administrating chemotherapy in patients with multiple CRC metastases limited to the liver after R0 liver resection. [less ▲]

The purpose of this talk is to present recent advances and developments of the R package catR. This package allows for random generation of response patterns under computerized adaptive testing (CAT) and holds various options to select the first items, estimate ability, select the next item, stop the test and return final results. Two main improvements were realized. First, several rules for next item selection were added, among others, Kullback- Leibler, progressive and proportional methods. Second, catR was limited to dichotomous IRT models so far. The most recent update allows now for several polytomous IRT models, such as partial and generalized partial credit model, graded and modified graded response models, rating scale model, and nominal response model. All improvements will be shortly presented, both from a theoretical point of view and in terms of practical implementation in catR. If possible, several illustrative examples will be displayed in a short live demonstration of catR. [less ▲]

Near-Death Experiences (NDEs) are classically associated with positive emotions like peacefulness, happiness and joy [1-3]. To date, few negative NDEs reports have been documented [4]. Although NDEs classically arise in the context of an acute severe brain damage, their associated memories are reported as being phenomenologically very rich and detailed [5]. To date, no satisfactory explanatory model exits to fully account for the rich phenomenology of NDEs following a severe acute brain injury [6]. Neurobiological hypotheses include cerebral hypoxia [7, 8] and temporal lobe dysfunctions [9] to account for some of the features occurring during NDEs. However, it has been recently shown that anoxic/hypoxic, traumatic and other supratentorial brain lesions do not seem to influence the content of a NDE when assessed with a standardized tool (i.e., Greyson NDE scale; [1]). Due to their particular brain lesion (i.e., pontine brainstem), locked-in syndrome (LIS) patients provide a unique opportunity to further investigate the neural correlates of NDEs. We here aimed at retrospectively characterizing the content of NDEs in patients with LIS having suffered from an acute brainstem lesion (cerebrovascular accident (CVA) or trauma; i.e., “LIS NDEs”) and to compare these experiences to those collected in a cohort of matched NDE experiencers after coma with supratentorial lesions (CVA or trauma; i.e., “classical NDEs”).

Cyprinid herpesvirus 3 (CyHV-3) is the causative agent of a lethal disease in common and koi carp. Since its emergence, in the late 1990s, CyHV 3 has caused severe economic losses worldwide creating a need for a safe and efficacious vaccine. With this goal in mind, recombinant strains deleted for single gene were produced using prokaryotic recombination technologies. While producing such a recombinant for ORF134, we unexpectedly obtained a clone deleted for ORF56 and ORF57 in addition to the expected deletion of ORF134. Interestingly, this triple deleted recombinant replicated efficiently in vitro, exhibited an attenuated profile and induced an immune protection against a lethal challenge in vivo. To determine the role of each deleted locus in the phenotype of the triple deleted recombinant, a series of recombinant were produced and tested in vivo. Firstly, to investigate the role of ORF134 deletion, a double ORF56-57 deleted recombinant and an independent triple ORF56-57-ORF134 deleted recombinant were produced. These experiments revealed that ORF134 deletion did contribute significantly neither to the attenuation nor to the immune protection observed for the triple deleted recombinant. Secondly, to determine the relative importance of ORF56 and ORF57 deletion in the attenuation observed, two single deleted recombinants were produced for ORF56 and ORF57. These experiments demonstrated that ORF57 deletion, in contrast to ORF56 deletion, correlates with an attenuated phenotype. Based on its safety-efficacy profile, the ORF56-57 double deleted recombinant was selected as a candidate vaccine. Complementary experiments were performed to further investigate the potential of this strain as a safe and efficacious attenuated recombinant vaccine. The results obtained can be summarized as follows: (i) In vivo imaging (IVIS) of vaccinated fish challenged with a wild type strain expressing luciferase as a reporter gene, suggested that vaccination induces a sterile immunity at the portal of entry. (ii) Study of viral tropism by qPCR, IVIS, and histopathological analyses, demonstrated that in comparison to the wild type parental strain, the vaccine strain replicates at lower level, at later time post-infection and for a shorter period of time. (iii) Transmission studies demonstrated that there is no detectable spread of the vaccine from freshly vaccinated fish to naive fish located immediately down stream of vaccinated fish (water sharing). All together, the results of the present study demonstrate the potential of ORF56-ORF57 double deleted CyHV-3 recombinant strain for safe and efficacious mass vaccination of carp. [less ▲]

Several insect species are known to have different morphotypes, an adaptation to heterogeneities in changing environments. This phenotypic plasticity could be a factor used by the Multicoloured Asian Ladybird, which is considered as an invasive species in Europe since its introduction in the 80’s. Harmonia axyridis has four major morphotypes: 2 melanic forms, conspicua and spectabilis; and 2 non-melanic, succinea and axyridis. In Belgium, only the three first are observed. Literature reports variations in morphotype frequencies, across native and introduced strains. These variations seem to be linked to climate (geographical and seasonal variation), with non-melanic forms being the most abundant in hot and arid climate. This study focused on the variation of morphotype abundance in H. axyridis according to season, field and gender. Adult ladybirds were caught from mid-July to mid-October 2012 into 5 maize fields. The proportions of observed morphotypes were compared according to the sampling season. The abundance of morphotypes was not significantly different through the fields; the observed ratios were 81.6%, 15% and 3.4% for succinea, spectabilis and conspicua respectively. Succinea was the most observed morphotype (χ2=755.8; P<0.001). The total number of collected males and females was the same with ratios of 48.2% and 51.8%: (χ2=0.93; P=0.33). The sex ratio was also not significantly different for each morphotype. There was no evolution of melanic and non-melanic form ratio according to the season, with 25.6% of melanic form in summer and 20.6% in autumn (χ2=1.22; P=0.27). Our results seem to show that morphotype adaptation according to the climate is not observed for Belgian ladybirds. [less ▲]

Maintaining the overall stability of active riverbeds requires a deep understanding of the complex interactions between turbulent flow forces and forces stabilizing the riverbed. Standard approaches do not properly take into account the turbulence fluctuations in non-uniform flows, while these are of primary importance in the mechanisms determining the stability of stones. In a new approach, the flow forces are quantified by means of parameters combining explicitly the velocity and turbulence distributions over a certain water depth above the riverbed. In this paper, as an onset for using these newly developed bed stability parameters, we report on new experimental measurements of velocity and turbulent kinetic energy based on acoustic methods, whereas all previous uses at the new bed stability parameters relied on Laser PIV Techniques. For quasi-uniform and non-uniform flow conditions, velocity measurements were conducted with two complementary devices: an ultrasonic velocimeter probe (UVP) and an acoustic Doppler velocimeter profiler (ADVP). The results are compared and discussed in detail. A general consistency between the two types of measurements is obtained, while some discrepancies are highlighted close to the bed and tentative explanations are given. [less ▲]

Purpose: Successful downstaging of hepatocellular carcinoma (HCC) into the Milan criteria (MC) remains a controversial indication for orthotopic liver transplantation (OLT). In Belgium, successful downstaging of HCC is an accepted non-standard- ized exception (NSE) for liver allocation. This NSE group rep- resents a unique cohort to analyse if OLT can be safely offered to patients with those extended allocation criteria. The aim of this study is to compare the overall and recurrence free survival after cadaveric OLT between patients with successful downstaging (MILDOWN) and patients always inside the MC (MILIN) from all Belgian transplant centres. Methods: We ret- rospectively analysed all patients listed for OLT with HCC and underlying cirrhosis between 12/2006 and 12/2011 from all Belgian liver transplant centres. Successful downstaging was defined as bringing a patient who was outside the MC into the MC after locoregional therapy (LRT). Results: Overall 381 patients were listed in Belgium during the study period. Of these, 320 received OLT. 248 were MILIN, 62 were MIL- DOWN and 10 were transplanted outside MC. Downstaging treatment included transarterial chemoembolization (TACE; n=26), radiofrequency (RF; n=9), transarterial radioembolisa- tion (TARE; n=4), resection (n=3), percutaneous ethanol injec- tion (n=2) and a combination of the above-mentioned therapies in 18 cases. In the MILIN group 67.3% received locoregional therapy before transplantation, with no significant differences in the distribution of treatment type compared to the MIL- DOWN group. At listing there were no significant differences between the MILIN and MILDOWN group for age, gender and underlying liver disease. Median time on waiting list between the two groups was similar (120 days vs. 115.5 days). Overall survival at 1 year was not significantly different between MILIN and MILDOWN (87.1% vs. 79%; p=0.120). 1.6% of patients were lost to follow-up in both groups. Although not significant, recurrence free survival at 1 year tended to be higher in the MILIN group than in the MILDOWN group (83.9% vs. 74.2%; p=0.073). Conclusion: In this large Belgian multicentre cohort, overall and recurrence free survival at 1 year are not signifi- cantly different between patients who have been downstaged successfully and patients who were always inside the Milan criteria. However, a longer follow up period will define, if the trend of lower survival in the successfully downstaged group becomes significant. Factors associated with HCC recurrence have to be identified.

The algae Caulerpa racemosa var. cylindracea (Sonder) was first observed along Corsican coasts in 2002 (Ruitton et al., 2005), and more recently in the Calvi Bay (northwestern Corsica) in 2008. Numerous works have studied the distribution of that invasive species and the factors driving its rapid expansion, as well as the resulting ecological impacts on native coastal communities (Klein and Verlaque, 2008). However, very little is known regarding C. racemosa biochemistry and its natural ability to concentrate trace elements (TEs). In the framework of the STARECAPMED project, this work therefore aimed to study the bioaccumulation and the compartmentalization of 19 TEs in this macroalgae. [less ▲]

In this contribution, the formability of sheet metal cut edges is investigated using damage model.Classical forming limit diagrams are known not to apply properly to the cut edges. However, with mild steels the sheet edges usually behave better than the Forming Limit Diagram prédictions, so this phenomenon has not been given sufficient attention. In contrast, for Advanced High Strengh Steels the cut edges exhibit reduced formability as compared to the plain sheet;this effect is very sensitive to the quality of the cutting process. The current investigation is aimed to evaluate the ability of available damage models to predict this effect on sample applications. The Gurson-Tvergaard-Needleman model is used and the material parameters for a Dual Phase are considered [1]. The effect of the cutting process is described by means of initial fields of equivalent plastic strain and porosity. The geometrical distribution and typical values for these two initial fields are devised based on literature . Numerical simulations of flat notched tensile tests are used within the FE code Abaqus/Explicit to illustrate the impact of the initial fields on the moment and the location of the failure initiation. The influence of the mesh size in the cutting-affected area is also investigated. The hole expansion test and a flat bending test are further simulated to investigate the influence of the cut edge.

Solvent degradation is a major drawback for the large-scale implementation of post-combustion CO2 capture due to amine consumption and emission of degradation products. In the present work, we refine a previous kinetic model for describing solvent oxidative and thermal degradation based on experimental results. The CO2 capture process is then modeled in Aspen Plus with assessment of solvent degradation. As a result, this work provides a useful tool for the identification of optimal operating conditions that minimize both the energy and environmental impacts of the process. [less ▲]

Marine ecosystems underwent several profound crises throughout the Mesozoic; many of them are correlated with supra-regional to worldwide anoxic events. The impact of these crises is relatively well understood among animals occupying lower trophic levels but their influence on top predators of that time, fishes and marine reptiles, remains unclear. The fossil record of marine reptiles is of fluctuating quality but thoroughly revised taxonomic and phylogenetic frameworks now allow assessment of the influence of past climatic and oceanic changes on these top predators, by quantifying their cladogenesis and extinction rates across selected intervals. Here, I focus on ichthyosaurs, a successful clade of marine reptiles that colonized marine ecosystems during most of the Mesozoic. The ichthyosaur record indicates relatively few severe turnovers and a non direct relationship with environmental drivers, notably anoxic events. New fossils from France reveal the middle-late Norian extinctions did not eradicate the clade of whale-sized shastasaurid ichthyosaurs; similarly, the severe early Toarcian anoxic event, the end-Jurassic climate changes and several Cretaceous anoxic events did not impacted ichthyosaurs significantly, at least at the suprageneric level. On the other hand, severe turnovers or extinctions occurred during the latest Triassic and the Cenomanian and are coincident with a number of profound environmental and biotic changes. This indicates that unique drivers fail to explain the turnover patterns in ichthyosaur evolutionary history. Notably, oceanic anoxic events only impacted ichthyosaurs during the end-Cenomanian and did so during a period of intense climatic and biological upheavals. These major crises in ichthyosaur history are seemingly protracted over several million years and are probably best explained by a conjunction of causes. This is part of a wider project that will incorporate data from other contemporaneous groups to shed a new light on the general turnover patterns among marine top predators of the Mesozoic and the influence of ancient environmental changes in shaping their biodiversity.

A ce jour, aucune phéromone sexuelle n’a pu être mise en évidence chez les Coccinellidae. Cependant, diverses études suggèrent que de telles molécules sont impliquées dans la communication sexuelle chez les coccinelles. Afin de vérifier cette hypothèse, nous avons collecté les composés organiques volatils émis par la coccinelle asiatique, Harmonia axyridis (Pallas), en présence ou en absence de pucerons. En présence de pucerons, les femelles vierges présentent un « comportement d’appel » qui est notamment associé à l’émission d’une phéromone sexuelle volatile chez plusieurs espèces de Coléoptères. D’autre part, des tests éthologiques ont démontré que les femelles émettent des composés volatils qui attirent les mâles à distance. Enfin, les prélèvements ont été analysés par chromatographie en phase gazeuse couplée à la spectrométrie de masse. Les analyses ont mis en évidence cinq composés volatils spécifiques provenant des femelles, aucun d’entre eux n’étant émis pas les mâles. L’identification a révélé la présence de (–)-β-caryophyllène, de β-élémène, de méthyl-eugénol, d’α-humulène et d’α-bulnésène, exclusivement produits par les femelles nourries de pucerons et dont les quantités respectives augmentent progressivement au cours de la période de prélèvement. Les résultats confirment donc que les femelles H. axyridis produisent une phéromone sexuelle volatile. Ceux-ci devraient permettre de promouvoir le développement de méthodes de gestion plus efficaces afin de manipuler les mouvements de cette coccinelle invasive et de réduire les impacts négatifs qu’elle occasionne sur la biodiversité.

Un inventaire des Coccinellidae provenant de la collection de l’unité d’Entomologie fonctionnelle et évolutive (ULg - Gembloux Agro-Bio Tech) a été réalisé sur une période s’étendant de 2001 à 2009. Cette collection est essentiellement constituée de récoltes fournies par les étudiants de première Bachelier de Gembloux Agro-Bio Tech. A travers ce recensement, nous avons étudié l’évolution des espèces récoltées au sein de cette famille, en termes d’effectif relatif et de richesse spécifique. Notre étude s’est focalisée sur les données issues de Wallonie et de la Région de Bruxelles-Capitale, car trop peu de collectes ont été réalisées en Flandre. Parmi les individus identifiés, 27 espèces ont été observées, dont 21 appartiennent à la sous-famille des Coccinellinae, 2 à celle des Epilachninae et 4 à celle des Chilocorinae. La plupart des espèces sont communes à la Belgique. Cependant, Harmonia axyridis (Pallas 1773), espèce originaire du sud-est de l’Asie, a été introduite sur le territoire belge en 1997. Cette coccinelle exotique a fait son apparition dans les collectes de 2002 et son effectif ne cesse d’augmenter au fil des années prospectées. En parallèle à cette augmentation, une diminution de la richesse spécifique, ainsi que de l’effectif relatif d’Adalia bipunctata (L. 1758), de Propylea quatuordecimpunctata (L. 1758) et de Psyllobora vigintiduopunctata (L. 1758), est observée.

The Multicoloured Asian ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is one of these species which was intentionally introduced for biological control and has spread from its native range in Central and Eastern Asia to large parts of North and South America, Europe, and Africa. The decline of native species is linked to the spread and the aggressive behaviour of H. axyridis. From 2009, we evaluated the population densities of aphids predator and predator diversities, with a special focus on H. axyridis in agroecosystems of Wallonia (South of Belgium). First, field crops preferences of H. axyridis were determined. Later, changes linked to aphid’s predator populations over time were evaluated. Finally, H. axyridis population changes between two crop farming methods were also evaluated. Samplings performed in agroecosystems highlighted that the community of aphid's predator is composed of few dominant species: three coccinellids (Coccinella septempunctata L., P. quatuordecimpunctata L., and H. axyridis), one syrphid (Episyrphus balteatus De Geer), and one chrysopid (Chrysoperla carnea Stephens). We demonstrated that H. axyridis do not invade all crops at the same rate, maize and broad bean being more infested than wheat and potato at both larval and adult stages. Moreover, H. axyridis populations in maize have strongly increased from 2009 to 2011. Finally, we showed that organic farming do not contribute to increase the abundance of H. axyridis but leads to increase the total abundance of aphid’s natural enemies. [less ▲]

En Belgique, les compétitions proposées aux enfants de moins de 10 ans sont des modèles réduits des compétitions d'adultes. Face au constat de retard, la Ligue Francophone Belge d'Athlétisme a mis sur pied un groupe de réflexion qui a décidé d'organiser une première compétition Kid's Athletics. [less ▲]

We consider a price signal with two settings: off-peak tariff and on-peak tariff. Some loads are connected to specific electricity meters which allow the consumption of power only in off-peak periods. Historically, off-peak periods were located during the night and on-peak periods during the day. Changing the assignment of off-peak periods is an easy method for distribution system operators to access to the flexibility of small consumers. This solution can be implemented quickly as the infrastructure needed already exists in some countries. We propose a mixed-integer linear model to assign optimally the off-peak hours so as to minimize a societal cost. This cost gathers together the cost of electricity, the financial losses due to energy curtailments of photovoltaic installations and the loads' wellbeing. Our model considers automatic tripping of inverters and constraints of the electrical distribution networks. Simulation results show that the new disposition of off-peak hours could reduce significantly the photovoltaic energy curtailed in the summer. [less ▲]

Raman spectroscopy has been selected as a non-destructive powerful analytical method for forthcoming planetary exploration. In the context of the upcoming ExoMars and NASA 2020 missions (developed by the European Space Agency, IKI Roscomos and NASA) analysis of the biological and geological terrestrial analogues using laboratory instrumentation is of great importance; especially testing the performance of flight-like operating modes and conditions on the feasibility of flight instruments meeting their science goals. Here we present a set of measurements of terrestrial analogues (among them desert varnishes) selected in preparation for in-situ Raman analysis on Mars. Laboratory instrumentation has been used to fully characterise the samples in addition to being operated in modes consistent with ExoMars RLS instrument flight designs, sample preparation and delivery. We discuss the performance of the spectrometers regarding the detection of the target signatures and their geological context. The impact of instrument operating modes and application of flight instrument sampling philosophy (i.e. spot size, grain size, number of target locations, sample preparation and delivery) on the signal intensity and the limits of detection are also discussed.

The Mediterranean seagrass Posidonia oceanica (L.) Delile is regarded as a relevant indicator of bioavailable trace elements (TEs) since it efficiently and proportionally bioaccumulates these chemicals from its surrounding environment. Recent studies have further brought supplementary insights in our understanding of the processes driving TE kinetics within that species. But at a higher degree of organization, the distribution and flows of TEs between P. oceanica meadow components, i.e. seagrass shoots, epiphytes, associated algae and animals and detritus, have not been investigated yet. The present study therefore aims to propose a conceptualization model of P. oceanica meadows, regarded as the juxtaposition of the 5 separate components listed above exchanging flows of TEs between themselves and with their environment, i.e. water and sediment. This model can be drawn in energy circuit language. By writing such a model, one in essence is writing equations describing a system. To be relevant, its elaboration requires the compilation of a large amount of quantitative data. This conceptualization can thus be regarded as a collaborative innovation requiring scientists to fill the model through the continuous supplement of new data. In fine, this model will lead to the exact quantification of the role played by P. oceanica meadows in the coastal biogeochemistry of TEsin the Mediterranean. [less ▲]
