Longtemps décrié dans l’espace public et ignoré dans le champ de la recherche francophone, le jeu vidéo occupe aujourd’hui une place de choix dans les pratiques et les discours en Belgique et en France. Dans le cadre de nos recherches, nous nous sommes intéressée à l’histoire de cette transformation progressive du statut du médium : nous avons pu mettre en évidence plusieurs processus de légitimation — qui touchent à la fois au jeu vidéo comme pratique et comme objet culturel, patrimonial et artistique — et qui affectent actuellement son image sur notre territoire. Fondée sur l’étude de ces différents processus, notre communication aura pour objectif de retracer l’évolution du statut du jeu vidéo en Belgique et en France au cours des dernières décennies, passant d’un objet commercial controversé à un produit culturel digne d’intérêt.

A pseudo-Boolean function is a real-valued function of 0-1 variables. Every pseudo-Boolean function can be represented by various analytical expressions, e.g., as a polynomial in its variables, or as a polynomial in its variables and in their Boolean complements, or as a disjunctive form, or as pointwise minimum of a family of affine functions, and so forth. Motivated by the problem of minimizing pseudo-Boolean functions, we consider yet another class of representations. Namely, we say that g(x,y) is a quadratization of the pseudo-Boolean function f(x) if g(x,y) is a quadratic pseudo-Boolean function of x and of m auxiliary binary variables y such that, for all x, f(x) = min g(x,y), where the minimum is taken over all possible values of the y-variables. It can be shown that every pseudo-Boolean function has at least one, and usually, many quadratizations. In recent years, several authors have proposed to reduce the problem of minimizing an arbitrary function f(x) (say, expressed as a high-degree polynomial) to the (presumably easier) problem of minimizing one of its quadratizations. In this talk, we discuss the size of ``small'' quadratizations, that is, the number of auxiliary variables required in any quadratization. We provide lower and upper bounds on the number of auxiliary variables for the case of an arbitrary function f(x), as well as for the special case where f(x) is a symmetric function of its variables.

For the 10 last years, terrestrial and satellite (GRACE) gravity measurements have reached such a precision that they can be of interest to better monitor underground water masses. First, we show that terrestrial measurements provide high-precision information about the time evolution of mass changes in the few kilometres square around the gravimeter. Then, examples of the possibilities and limitations of terrestrial measurements are given in Membach, close to Eupen, and in the Rochefort karst system. In Membach, we show that the evapotranspiration can be directly inferred from continuous gravity measurements: as water evaporates and transpires from terrestrial ecosystems, the mass distribution varies through the system, changing its gravity field at the level of, or smaller than 10-10 g per day. This corresponds to 2.0 mm of water over an area of 50 ha. The strength of this method is its ability to ensure a direct, traceable and continuous monitoring of actual ET for years at the mesoscale (~50 ha) with a precision of a few tenths of mm of water. In Rochefort, gravity measurements at the surface and in the cave allows separating the water contained in the unsaturated zone from the saturated one and therefore monitoring groundwater content changes that occur in the unsaturated zone only.

Une des priorités contemporaines en éducation scientifique est d’envisager une utilisation des acquis de la recherche en didactique des sciences pour la formation afin que la recherche qui parle des pratiques d’enseignants parle également aux enseignants. Les formateurs ont, dans cette perspective, un rôle de passeurs à jouer. Il serait utile de définir les conditions nécessaires pour que les apports des chercheurs deviennent un éclairage usuel du praticien. Ces conditions sont relatives au mode d’accompagnement et à la posture du formateur; au contenu de la recherche elle-même; au parcours de l’enseignant; aux attentes prescrites… C’est par l’analyse d’exemples vécus d’intégration réussie, ou non, d’apports de la recherche dans la construction de réponses à des questions d’ordre didactique par des enseignants en formation, que nous tenterons de repérer des conditions favorables à une telle intégration.

Key words : Family Practice / Community-Based Participatory Research / Intergenerational Relations / loyalty conflict Introduction “Would you consider yourself more Turkish or more Belgian”? To make a choice between Belgium and Turkey is like making one between my mother and my father claims a Belgian-Turkish teenager. That reveals the deep feeling of the descendants of the Moroccan or Turkish immigration in Belgium we commemorate the 50th anniversary this year. When two objects of desire are in contradiction with each other, that may give rise to a loyalty conflict. And that is exactly what we are interested in: the loyalty feeling between parental culture and the one of the native country. This project aims to take interest in the fruits of the immigration and more particularly in the teenagers born of immigrant parents in Belgium by the realization of a video by whom it concerns first, with the help of professionals. How do these teenagers daily manage this far-out situation? The aim of this project is to illustrate these silent questionings. The realized video will be broadcasted in schools to allow other teenagers to identify with the characters and to open up the debate. Methods The non-profit association ETMS (Private health center Espace Temps) has signed a partnership declaration with the Regional Center of Immigration of Charleroi and the non-profit association Accompaniment of Teenagers in Open Custody (AJMO) to elaborate a participatory research in community health. Recruitment of participants, meetings with the teenagers, storylines writing, shooting, editing and presentation of the video to an interested audience were the following steps. Results A psychologist, a family doctor, a nurse practitioner, a cameraman, a social worker, an educator and six teenagers of Turkish, Moroccan or Algerian origin take part to the project that has lasted for one year. The video will be ready end 2015 and will allow to debate sensitive topics and the creation of a partnership with schools that are interested in using this tool for educational purposes. [less ▲]

Perinatal brain injury is a major contributor to neonatal morbidity and mortality and is a common cause of disability with devastating impact on individuals and families. The mechanisms involved in the genesis of brain lesions depend of the the gestational age at which brain development is altered. In the term infant, the most common pathology implicated in brain damage is hypoxic-ischemic encephalopathy (HIE). HIE is the consequence of an excitotoxic cascade leading to cortical and/or basal ganglia lesions. Therapeutic hypothermia induced in the 6 hours following HIE reduces the risk of death or major neurodevelopmental disability in the neonate with moderate or severe encephalopathy and is the only neuroprotective treatment available in clinical practice. Research is now being focused on other promising strategies such as xenon, allopurinol, N-acetyl cystein, melatonin, anticonvulsant, erythropoietin or stem cell transplantation. In the preterm infant, diffuse white matter injury (dWMI) is the main pathological condition associated with neurological impairment. Based on experimental models, pathophysiological mechanisms of dWMI potentially include infection/inflammation, hypoxia-ischemia and oxidative stress. Experimental studies suggest a sensitizing effect of systemic inflammation that makes the perinatal brain more vulnerable to further insults. Antenatal magnesium sulfate therapy given to women at risk of preterm birth substantially reduced the risk of motor disorders in childhood but is unfortunately unable to reduce long term cognitive impairment or behavioural disorders. Antenatal steroids and caffeine therapy for apnea of prematurity are two other treatments with positive impact on neurodevelopment. Randomized controlled trials studying erythropoietin or melatonin are currently under process. Finally, research performed at the University of Liege suggests that Estetrol (E4), an estrogen synthetized exclusively by the human foetus, has neuroprotective properties in animal models of HIE as well as in inflammatory-induced dWMI.

The State archives in Liège preserve some of the 16th century “fabrique“ accounts of the Saint Denis collegiate church of Liège. Among them, accounts of the year 1533 drew the attention of Jean Yernaux in his 1958 study about Lambert Lombard. Indeed he found what he thought to be the proof of the Liège Renaissance Master’s intervention in the painting of the Saint Denis Altarpiece panels, before giving up the attribution in 1970. Since then, these two mentions have been used to illustrate either the involvement of Lombard or of another painter named “Lambert” in the painting of the panels. But looking closer at the original document, it is obvious that Yernaux committed huge mistakes in the transcript of these mentions. Not only was he wrong about the sums paid to the artist but also about the work mentioned in this account. In order to understand this document fully and correctly, it is therefore essential to propose a transcription from which new interpretations can be generated. This new understanding can then lead to further contextualization of the mentions. These accounts need to be looked at in close relationship with the rest of the document. This would shed new light on the writer’s habits, especially when it comes to designate individuals. The amount of money given to the painter Lambert also needs to be assessed. Comparisons to other payments of the same period conserved in the archives of the Saint Denis church and of other churches in or around Liège are going to be unveiled and investigated. This will give interesting clues to understand better the extent of the work done by the artist as well as his social status. [less ▲]

Les spécificités et les difficultés de la « lecture pour apprendre » au début du secondaire sont à l’origine du projet de recherche longitudinale de type quasi-expérimental dans lequel s’inscrit notre contribution. « Lirécrire pour apprendre » a pour principaux objectifs d’expérimenter, durant deux années successives (2014-2016), un programme didactique centré sur le développement de la compréhension et de la production des textes à visée informative-explicative ; de tester la valeur de cet outil sur un large échantillon d’élèves du premier degré de l’enseignement secondaire et d’évaluer les conditions d’implémentation et de mise en œuvre de l’outil les plus favorables au changement de pratiques pédagogiques et au maintien de l’innovation. Dans le cadre de cette contribution, à l’issue de la première année de l’expérimentation, nous évoquons quelques éléments de définition et de modélisation préalables (première partie), quelques-uns des constats posés en amont de la conception du programme (deuxième partie) ainsi que le design de la recherche et les caractéristiques du dispositif didactique (troisième partie). Ces éléments constituent le cadre de référence dans lequel s’inscrit l’étude développée dans la quatrième partie du texte, relative aux premiers résultats quantitatifs de l’expérimentation du dispositif. Les données recueillies auprès d’un échantillon de 1690 élèves (scores bruts), limitées aux apprentissages en lecture, sont examinées à la lumière de la question suivante : les élèves peuvent-ils, sous l’influence d’un outil structuré, progresser dans leur capacité à comprendre un texte ou un dossier de documents informatifs-explicatifs et à rendre compte de leur compréhension ? Seule l’évolution des performances des élèves est ici étudiée. Deux autres variables prépondérantes, qui influencent les résultats des élèves, à savoir l’appropriation de l’instrument didactique par les enseignants ainsi que les pratiques effectives d’enseignement, seront analysées ultérieurement, à la lumière de l’ensemble des données de la recherche.

Dans les matériaux de construction, la notion d’environnement et d’empreinte des produits devient de plus en plus importante que ce soit dans un cadre législatif ou comme objet de marketing. Dans ce contexte, des études environnementales ont été réalisées sur divers produits belges en pierre bleue (dalles, bordures, marches) ainsi qu’en grès (pavés). Ces études ont été menées en utilisant la méthodologie de l’Analyse du Cycle de Vie (ACV) et ont permis de mettre en évidence les étapes prépondérantes de leur production dans une optique d’écoconception ainsi que de les comparer à d’autres produits sur le marché tels que leurs concurrents asiatiques. Les frontières du système comprennent les étapes depuis l’extraction des matières premières, en passant par la production des produits finis ainsi que leur transport sur chantier situé en Belgique. Cette présentation reprend le pourquoi et le comment d’une Analyse du Cycle de Vie, les différentes étapes nécessaires à l’application de l’ACV aux produits en pierre belge ainsi que les principaux résultats. Cette présentation permettra la mise en évidence de l’intérêt de l’ACV et des fiches de déclaration environnementale qui y sont associées ainsi que les perspectives qui peuvent en découler dans le domaine des matériaux et plus précisément pour les matières minérales.

Context: Family physicians are large producers of knowledge. The site of Wonca Europe provides access to almost 20,000 abstracts produced by family physicians since 1995 (from Europe) and 1998 (from World Conferences). On the occasion of 20 years of Wonca Europe, an editorial committee selected 100 of the best abstracts and has asked each author (or a substitute) to make a chapter for the Wonca Book published in 2015 at the Wonca Europe congress. The content analysis of medical texts is generally achieved by the use of MeSH. To fill gaps in MeSH, a specific family medicine classification has been developed under the name Core Content Classification of General Practice / Family Medicine (3CGP). A combination of ICPC + Q-Codes (new tool for non-clinical items) provides just fewer than 900 concepts for analyzing the contents of specific texts to family medicine. Method: The 100 chapters of the Wonca Book 2015 were analyzed using 3CGP by a single observer not involved in the editorial committee of the book. Every text has been carefully read and a maximum of two concepts by chapter were reported in an Excel spreadsheet. Result: 150 codes were used of which 143 from the classification of non-clinical items Q-codes and 7 coming from ICPC. Among the topics discussed by 143 authors and identified by Q-codes, 35 relate to knowledge management which includes family medicine education, 29 codes concern research and development, 29 doctor's specific area, 24 patients’ issues, 11 relate to the structure and 8 deal with ethics. Discussion: Despite limitations (unique observer – not validated tools) the study reveals striking facts. It is noted that the editorial board has favored themes that affect the structure and organization of knowledge of the profession. Clinical items or affecting directly the patients are very poorly represented. More about 3CGP on http://docpatient.net/3CGP The chapter of the book are also used as source of knowledge in the Q-Codes content study (ongoing) available on www.hetop.eu (inscription needed) [less ▲]

In order to study N2O exchanges by a Belgian production crop, we installed an eddy covariance system at the Terrestrial Observatory of Lonzée (Belgium), using a H2O and N2O quantum cascade laser analyzer and a sonic anemometer. We obtained three days of measurements and were able to investigate data preprocessing and flux calculation. We observed a drifting time-lag between the analyzer and the anemometers time series, presumably caused by an internal clock drift. Time-lag determination (using the covariance function maximum method) was more difficult for N2O than H2O, suggesting that this routine should be adapted to gas characterized by low fluxes. We investigated high frequency loss and found a system cut-off frequency of 0.5Hz for H2O, comparing its cospectrum to sensible heat cospectrum. We were not able to retrieve a neat cospectrum for N2O because of low fluxes during turbulent conditions. Further work and more data will be needed in order to bring answers to pending questions.

Dopaminergic neurons (DA) within the substantia nigra pars compacta (SNc) and ventral tegmantal area (VTA) are autonomous pacemakers. SNc DA neurons are particularly prone to degeneration in Parkinson’s disease (PD). However, the cause for their high vulnerability to degeneration, compared to the neighboring, more resistant VTA DA neurons, remains unclear. It has been suggested that the pacemaking in SNc DA neurons relies on L-type calcium channels. A large calcium entry through these channels could cause oxidative stress in SNc DA neurons and could explain their vulnerability. We directly tested this hypothesis in young rats by quantifying the density of L-type calcium channels in the soma of DA neurons using nucleated patch-clamp recordings. Our results show measurable L-type (sensitive to 5µM nifedipine) and non L-type calcium currents in the soma of SNc and VTA DA neurons. We found that the amplitude of the nifedipine-sensitive current is higher in SNc DA neurons (17.8±1.6 pA/pF; n=10) than in VTA DA neurons (11.2±1.8 pA/pF; n=10). Interestingly, we noticed that the L-type current is the predominant Ca2+ current in SNc DA neurons (44%) while this is not the case in VTA DA neurons (22%). These results were confirmed by non-stationary-fluctuation analysis (NSFA). These experiments revealed a higher mean number of nifedipine-sensitive Ca2+ channels in the soma of the SNc DA neurons (502±74; n=6) than in VTA DA neurons (160±45; n=6). The greater density of L-type channels in the soma of SNc DA neurons could contribute to their vulnerability in human PD patients. [less ▲]

Paraneoplastic hypercalcemia and hypercalcemia associated with neoplastic syndromes are particularly resistant to conventional hypocalcemic treatments. We present and discuss two case reports in which Cinacalcet was used to control hypercalcemia. Paraneoplastic hypercalcemia is present in the first case report, in association with a metastasic neuroendocrine pancreas. In the second case report ,cinacalcet is used to control hypecalcemia in a patient with multiple endocrine neoplasia and hyperparathyroidism not controlled by neck surgery. Cinacalcet is an oral agonist of the Calcium Sensing Receptor. The hypocalcemic effects of Cinacalcet have not been documented so far in hypercalcemia-paraneo plastic linked to cancer of the pancreas (Valdés-Socin & al. Rev Med Switzerland 2009). On the other hand, its use seems promising in the MEN1-associated hyperparathyroidism. (Giusti & al. Endocrine 2015). [less ▲]

La dysphasie est un trouble spécifique du développement du langage oral qui fait l’objet de nombreuses recherches mais dont certains aspects sont encore mal connus. Les théories explicatives de ce trouble prolifèrent, notamment suite au développement de l’approche cognitivo-fonctionnelle du langage qui permet de concevoir celui-ci comme étant en interaction avec des processus généraux et non-linguistiques. En particulier, la théorie des grammaires de construction soutient que le langage s’acquiert par une abstraction progressive des formes entendues qui deviennent alors des schémas de construction. Ce mécanisme serait lié au raisonnement analogique. Or, les enfants présentant une dysphasie semblent détenir de faibles capacités de raisonnement analogique par rapport à leurs pairs de même âge. Nous nous demandons donc à quoi pourrait être dû ce déficit, en nous intéressant à un élément déterminant du raisonnement analogique : la connaissance relationnelle. Une tâche de scènes analogiques a été proposée à un groupe d’enfants présentant une dysphasie et à deux groupes contrôles, l’un apparié en âge linguistique et l’autre en mémoire de travail. Les participants devaient sélectionner l’élément détenant le même rôle relationnel qu’un élément pointé dans un dessin présenté au préalable. Les relations étaient similaires pour chaque item mais la nature des indices perceptuels variaient selon la condition : dans une condition, les indices perceptuels et relationnels concordaient, alors que dans une autre ils discordaient. Dans une troisième condition, aucune similarité perceptuelle n’était présente. Tous les enfants semblent bénéficier de la congruence entre informations perceptuelles et relationnelles. De plus, les enfants présentant une dysphasie détiennent des compétences de raisonnement analogique semblables à leurs pairs de même âge linguistique et de mêmes capacités de mémoire de travail. Ils semblent également posséder des connaissances relationnelles relativement préservées par rapport à leurs pairs de même âge mais des difficultés apparaissent quand la tâche se complexifie, notamment quand des distracteurs perceptuels doivent être inhibés. Ceci semble pouvoir être expliqué par les troubles langagiers et les déficits en mémoire de travail liés à la dysphasie. De futures études devront néanmoins écarter l’hypothèse d’une différence qualitative des représentations relationnelles entre des enfants présentant une dysphasie et d’autres ayant un développement langagier normal.

In this paper is presented the analysis of a concrete building exposed to OZone fire. The temperature development in the elements and the structural behaviour were calculated in SAFIR using beam elements for the columns and beams and shell elements for the floor slabs. The first floor was modelled and the effects of action from the upper storeys are applied as external loads. It is shown how the numerical analysis allows understanding the behaviour of the structure when exposed to a natural fire until complete cooling by analysing the evolution of displacements, the distributions of bending moments in the beams, the membrane forces in the slab, and the stresses in the elements. All this detailed information would not be available from an experimental test. [less ▲]

Despite growing recognition that the technical and social dimensions of technology development are coproduced, research and policymaking in the nuclear field is still predicated on the separation between both dimensions. This paper explores how this separation is enacted, and occasionally questioned and transformed, within the Belgian context of nuclear technology. It situates the emergence of a science policy support (SPS) unit and programme (PISA) within the Belgian Nuclear Research Centre SCK•CEN as an institutional response to the need of integrating societal and ethical concerns into nuclear research. The paper elicits how since 1999, SPS/PISA draws together science and technology studies (STS) and technology assessment (TA) approaches, creating links between nuclear research innovation and society in mutually beneficial ways. To this end, it first outlines the four areas in which SPS/PISA researchers are active: 1. Ethics of nuclear technology assessment; 2. Radioactive waste management; 3. Safety governance; 4. Perception and communication of ionising radiation risks. As SPS/PISA research is situated in a trading zone that embeds scholarship, nuclear research and research policy, the paper illuminates the growing entanglement of the natural and social sciences, and the roles social scientists play in the development of contemporary technologies and technology policy. Drawing on the notion of hybrid management (Miller 2001), the paper argues that SPS/PISA researchers must develop a language that underlines the interdependency between science, policy, and politics, while acknowledging that actors (policymakers, industry representatives, natural and social scientists, citizens) recurrently draw distinctions between these domains as a means of collectively managing nuclear issues. SPS/PISA research is therefore best understood as boundary work that mediates between various interests, values, and "knowledges." The paper concludes by discussing the key challenges SPS/PISA researchers face while engaging in work of this kind: maintaining professional independence and credibility, ensuring research continuity, and generating both scientific and policy impacts.

The Kabyle goat breed represents 10.52% of the total Algerian market (3.8 million heads). A survey of 69 farmers has been carried out in order to characterize it and its breeding in the District of Chemini. The questions focused on household agricultural activities, including breeding of goats, cattle, sheep, rabbits, chicken, turkeys, honeybees and the production of olive oil and figs. The goat morpho-biometric characterization was based on 18 corporal measurements. The Hierarchical Cluster Analysis (HCA) of the farm structures defined four groups of farms, variance between groups accounting for 55.7% of total variability. The average number of goats in groups 1 to 4 was 7.2±2.8, 11.1±3.5, 22.3±1.4 and 3.4±1.0, respectively. Group 3 (n=6), showed the greatest number; it consists of older farmers (67 years old or over) not practicing arboriculture. They also have the largest numbers of sheep (48.67), rabbits (50.83), chicken (48.33) and turkeys (42). Group 4 (n=9), with the lowest number of goats, was the group of young farmers (39 years old or less), more dedicated to cattle breeding (~52 heads) and the production of olive oil (~207 trees) and figs (~47 trees). The 18 morpho-biometric variables were significantly higher in males than in females (p<0.05). The Kabyle goat is small (male: 68.23±0.97cm and female: 65.41±0.55cm) with long hair (male: 12.24±0.51cm, and female: 9.51±0.29cm). Its ears are drooping, its convex profile has a slightly pronounced nasal split and its dress color ranges from dark brown to black. This adapted genetic resource should be key in the development of a local production, based on a strong commitment of farmers inside a breed association, for the production of specimens corresponding to a standard, to be determined collectively.

This paper investigates the impact of corporate board of directors’ (supervisory) attributes on conditional accounting conservatim in the French, German and British contexts. Using pooled regression model over the period 2009-2012, our findings report that the relationship between corporate board attributes and accounting conservatism is country dependent. First, regarding the board composition, we find that the effect of board size is positive for German firms, negative for French firms and insignificant for British firms. We also document a positive association between board independence and accounting conservatism for British firms. However, we find no evidence of a positive association between employee seats on the supervisory board and earnings conservatism in German context. Second, female seats on board seem to increase conservative reporting in financial statement only for French firms. Lastly, board meeting frequency in French and British firms appears to increase accounting conservatism. As a robustness test, we use an alternative measure of accounting conservatism namely, time–series of earnings changes measure and confirm the previous results. Overall, our results reveal that corporate board affects the financial reporting quality. [less ▲]

Biopreservation is the use of naturally occurring microorganisms and/or their inherent antimicrobial compounds to extend shelf life and to enhance the safety of foods. The aim of the present study was to perform a sensory evaluation of beef patties inoculated with potentially biopreservative strains of Carnobacterium maltaromaticum. Three different strains of C. maltaromaticum (lab. ref.: CM_824, CM_827 and CM_829) isolated from vacuum packaged beef with long shelf life were selected for this study. An untrained panel was requested to make a sensory evaluation of raw and cooked beef patties 8 and 10 days after inoculation with the selected strains at 104 and 106 UFC/g and storage in high-O2 atmosphere. After 8 days of storage, non inoculated samples (blank) were perceived as having the best studied sensory descriptors. The samples inoculated with strain CM_827 had a sensory quality very close to the blank. After 10 days of storage, samples inoculated with the strain CM_827 at 104 UFC/g received the highest scores for appearance and color. This study permitted to evaluate the effect of three C. maltaromaticum strains on the sensory quality of beef patties. Strain CM_827 did practically not change the sensory attributes of beef patties. Samples inoculated with strain CM_824 and CM_829 received the worst scores for several of the tested descriptors. Therefore, further research on the biopreservative capacity of C. maltaromaticum should be conducted with strain CM_827. [less ▲]

This work presents an analysis of the behaviour of different structural members under natural fires, with the aim to characterize their sensitivity to the fire decay phase. Thermo-mechanical numerical simulations based on the non-linear finite element method are conducted using the parametric fire model of Eurocode to represent the natural fires. Results show that, for all the studied members (column, beam) and materials (reinforced concrete, steel, timber), structural failure during or after the cooling phase of a fire is a possible event. The major factors that promote delayed structural failure are the thermal inertia and the constituting material of the member. An indicator is proposed to quantify the propensity to delayed failure for structural members under natural fire. This work enhances the understanding of the structural behaviour under natural fires and has implications for the safety of the fire brigades and people proceeding to a building inspection after a fire.

Avian primordial germ cells (PGCs) are precursor of gametes and appear during early stages of embryonic development. Under appropriate culture conditions, these cells can keep their germ cells properties in vitro and are foreseen as promising tools for developing efficient avian genetic engineering and preservation of germplasm. We propose original methods that allow long term expansion, efficient cryopreservation and genetic modification of primary cultures of undifferentiated PGCs. PGCs are collected from embryonic blood during their migratory period and grown in cell-culture insert in the presence of feeder cells (BRL). This physically separated co-culture system along with selective culture medium promoted emergence, selection and proliferation of PGCs lines. Forty percent of blood samples gave rise to lines originating from three commercial layer and two Belgian endangered breeds. PGCs lines were characterized for the expression of the stem cells and PGCs marker SSEA-1 by FACS. RT-PCR confirmed expression of germ-line specific markers (CVH, CDH, DAZL), pluripotency markers (cPouV, cSox2, cNanog), telomerase and CXCR4 receptor. All lines were male although isolated from pooled male and female blood samples. Two cryopreservation methods were developed based upon slow-freezing and aseptic vitrification. Both have shown a similar effectiveness in allowing storage without phenotype drift. Stably expressing lines were obtained by Lipofectamine® mediated transfection of a GFP plasmid. PGCs were subsequently injected in recipient embryos. Persistence of exogenous PGCs in the developing gonad of recipient embryos confirmed that PGCs retain their gonadal colonisation ability, both after long-term culture and after cryopreservation.

A binder is used to hold together the fibers forming the mineral wool products (see figure 1). These fibers can be produced from sand and recycled glass for glass wool products (see figure 2) or from rock (volcanic rock, typically basalt or dolomite) for stone wool products. Traditionally, the binders used in mineral wool products are based on phenol-formaldehyde. Due to sanitary and environmental considerations and increased focus on indoor air quality, the producers developed new alternative binders. Especially, Knauf Insulation, a worldwide building insulation manufacturer, developed a binder based on plant starch and called ECOSE. In addition of not using added phenol-formaldehyde , this new binder is also supposed to reduce the environmental impacts of Knauf Insulation mineral wools. Moreover, due to its properties, others applications are now considered for ECOSE such as composite wood panels [1]. The aim of this study is to determine the environmental impact of ECOSE and to compare it with more traditional binders using Life Cycle Assessment (LCA) methodology. LCA analyzes the environmental aspects and potential impacts associated with all the stages of a product's life. In this type of environmental assessment the energy and material flows for the entire life-cycle are surveyed and analyzed with special attention to possible environmental hazards or human health problems. The ISO 14040 and 14044 norms [2, 3] provide the general guidance for performing an LCA. The LCA methodology is first applied to ECOSE main component: glucose. The presentation will present results for glucose production from cereals starches After that, first ECOSE application, glass mineral wool products will be presented in details, including production process (see figure 3). The modelling of the glass mineral wool production process in LCA software GaBi 6 [4] is then described. One of the model specificity is that it allows to perform LCA of any glass wool products produced in Knauf Insulation plants in Europe. The adaptations to the model to allow studying former glass wool product when using phenol-formaldehyde binders will also be presented such as the advantages of this model. Moreover, preliminary results about ECOSE and phenol-formaldehyde glass wool products are explained. Références [1] Knauf Insulation. [cited 2014; Available from: http://www.knaufinsulation.ua/en.

This talk focuses on the computation of asymptotic standard errors (ASE) of ability estimators with dichotomous item response models. A general framework is considered, and ability estimators are defined from a very restricted set of assumptions and formulas. This approach encompasses most standard methods such as maximum likelihood, weighted likelihood, maximum a posteriori, and robust estimators. A general formula for the ASE is derived from the theory of M-estimation. Well-known results are found back as particular cases for the maximum and robust estimators, while new ASE proposals for the weighted likelihood and maximum a posteriori estimators are presented. These new formulas are compared to traditional ones by means of a simulation study under Rasch modeling. [less ▲]

Soumises à une clôture particulièrement stricte – qui impressionne les ecclésiastiques les plus rigoureux –, les annonciades célestes ne peuvent évidemment vivre dans l’isolement absolu inscrit symboliquement au cœur de leur spiritualité. Il en va de leur survie dans des contextes souvent difficiles. Sans nécessairement déroger à leurs règles austères, ces femmes entretiennent des relations suivies avec le « monde » pour divers motifs et dans diverses circonstances. Tout en affichant beaucoup de méfiance à l’égard de la « fréquentation des grilles », elles reçoivent pourtant quantité de visites et nombreux sont ceux qui sollicitent l’accès à leurs parloirs.

Les annonciades se retrouvent ainsi, bon gré mal gré, au cœur de réseaux sociaux qui servent ou desservent leur cause selon les cas.

Bryonia alba L. is a climbing species, spontaneous in the Romanian flora, which can be found throughout the whole country [1]. It is known for its cytotoxic, analgesic, antipyretic, anti-inflammatory, antibacterial, anti-rheumatic, laxative-purgative and smooth muscle relaxant proprieties, being used both in traditional medicine and in homeopathy [2]. The main objective of this study consists in the evaluation of the flavonoid profile of this species. The vegetal material was harvested from the spontaneous flora of Cluj county (Romania). The vegetal extracts were obtained by ultrasonication, in methanol. Analysis of flavonoids was performed by a HPLC-DAD method and revealed mainly the presence of C-glycosides, of which saponarine was found as the main compound. Quantification of saponarin was also performed, using the HPLC method, on samples collected at different periods of time. Variation of the quantity of saponarine according to harvested samples was determined. Further analysis are under process in order to investigate the structure of these flavonoids and the pharmacological effects of the Bryonia alba L. plant extracts.

When simulating a system based on the organic Rankine cycle (ORC), different modeling methods can be used to predict its performance. Each method is characterized by advantages, limitations and a level of complexity. This contribution aims to assess the impact of the modeling approach on the performance prediction of ORC systems. To this end, a 2.8 kWe ORC unit is investigated as case study. In this paper, the components of the test bench are modeled using different approaches of increasing complexity and each model is calibrated using experimental data from the test rig. The goodness of fit as well as the benefits and limitations of each modeling methods are analyzed and discussed. [less ▲]

Although the reproducibility of the protocol has been demonstrated by Bosquet et al. (2010), what about the reproductibility of the measured parameters and various "fatigue index" proposed by dynamometers and used in the clinic and in the literature? Material & method Seventeen subjects, moderately active, performed 30 reciprocal maximal concentric contractions on three occasions with one 7-10 days recovery between each session. The peak torque (PT) and the maximal work (MW) of each repetition computed and subsequently use to compile eleven measured parameters and build forty-four index. The reproducibility of each parameter and index was evaluated through their ICC (2,1), SEM and respective MD. Results The ICC values of the measured parameters for the knee extensors are almost always higher than 0.8 while those for flexor range between 0.7 and 0.8. The ICC values for built "fatigue index" are less than 0.7 and 0.5 respectively for the extensors and flexors. No significant difference was observed between the reproducibility of PT and that of MW (whether for the extensors or flexors or for the measured parameters and "fatigue index"). Discussion In view of the values obtained in our population, it appears that no "fatigue index"or calculated quotient (quotient of the last x repetitions by the first x or accumulated repetitions by the best,...) seems sufficiently reproducible for clinical or scientific use! Only the measured parameters such as the best repetition, total or partial sum have a (very) high or excellent reproducibility and can therefore be used in clinical or research domain.

Objective The aim of this study was to assess the compatibility between dynamometer Biodex System 3 Pro, Con-Trex MJ PM-2 and Cybex Humac CSMI of knee extensors and flexors. Material & method Twenty-one subjects, moderately active, performed three isokinetic evaluation sessions with six to ten days of rest between each. Each of it, performed on a dynamometer in accordance with a different randomized order, included a concentric evaluation (60°.s-1 & 240°.s-1), eccentric (30°.s-1) and fatigue-resistance protocol (30 concentric repetitions maximum 180°.s-1) for the knee extensors and flexors. The peak torque (PT) and the maximal work (MW) of each repetition were recorded, as well as concentric and mixed agonists/antagonists ratios, to measure the compatibility inter-dynamometer two by two through their respective ICC (3.1), SEM and MD. Results For the short maximal strength test, ICC values for the extensors are almost always higher than 0.85 in concentric mode although they don't exceed 0.61 in eccentric mode. The ICC values for the flexor in slow concentric and eccentric mode are above 0.7, 0.75 and 0.8 for pairs Biodex/Cybex, Biodex/Con-Trex and Cybex/Con-Trex. None of ICC value exceeds 0.75 in fast concentric mode for the flexors. The ratios have ICC values lower than 0.6 except concentric ratio at 60°.s-1 for the pair Cybex/Con-Trex (0.83) and mixed ratio for the pairs Biodex/Cybex (0.73) and Cybex/Con-Trex (0.77). The ICC values of the parameters measured during the extensors fatigue-resistance protocol are mostly above 0.8 regardless of the pair of dynamometers considered. The ICC values of these parameters for the flexors are almost all lower than 0.7. Discussion Although the reproducibility of extensors in concentric mode is high, it's important to inform users, whether in clinical or scientific domain, that different dynamometers provide regular incompatible results and we draw attention to the little reproducibility of the agonist/antagonist ratios. Our results justify the establishment of norms for each dynamometers brand in order to interpret, with relevance, the isokinetic test, either for short maximal strength evaluation or fatigue-resistance protocol.

Cet article a pour objectif d’ébaucher la construction d’une théorie du détournement de jeux vidéo par les joueurs en passant, non pas par une perspective sociologique ou anthropologique, mais par l’analyse formelle des œuvres dérivées. Pour ce faire, le présent travail prend pour objet une pratique spécifique de détournement, la réalisation de machinimas, et l’aborde à travers un corpus illustratif de vidéos ayant pour point commun d’être issues des jeux Halo. L’analyse détaillée de quatre exemples prototypiques permettra de démontrer, d’une part, l’intime continuité qui existe entre la production de détournements et la pratique même du jeu (continuité qui rend donc artificielle toute tentative de démarcation stricte) et, d’autre part, la nature duelle du détournement de jeux vidéo (due à l’existence de deux aspects à détourner : le game et le play). La mise en parallèle de ces réflexions aboutira, enfin, dans la formalisation d’un modèle cartographiant les multiples formes de détournements. [less ▲]

The bottlenose dolphin (Tursiops truncatus) is a major apex predator and the most common cetacean species found in nearshore waters of South Florida, including the Lower Florida Keys (LFK) and the Everglades National Park (ENP). The objective of this study was 1) to assess contamination levels of total mercury (T-Hg) in skin and persistent organic pollutants (PCBs, PBDEs, DDT, HCH, HCB, DLCs and PCDD/Fs) in blubber samples of bottlenose dolphins from the LFK (T-Hg : nmales = 10; POPs : nmales = 16, nfemales = 8) and the ENP (T-Hg : nmales = 13, nfemales = 9; POPs : nmales = 11, nfemales = 8). T-Hg and POPs were analysed by the mean of Direct Mercury analyser (for T-Hg), GC-ECD (POPs) and GC-MS (DLCs and PCDD/Fs). The PCBs were the main compounds found in bottlenose dolphins from the LFK and ENP. The most present congeners where the CB no. 28, 52, 101, 138, 153 and 180 (Σ 6 PCBs LFK males: 13420.5 ng.g-1 lipids, Σ 6 PCBs LFK females: 9683.4 ng.g-1 lipids, Σ 6 PCBs ENP males: 5637.9 ng.g-1 lipids, Σ 6 PCBs ENP females: 1426.9 ng.g-1 lipids), while the concentrations of DL PCBs remained low for both locations (LFK: 739 ng.g-1 lipids, ENP: 183 ng.g-1 lipids). PCBs concentrations were significantly higher in individuals from the LFK than those from the ENP. PCBs concentrations in LFK and ENP dolphins were significantly lower than those from other locations in the south-eastern US. Unlike organic pollutants, T-Hg concentrations were significantly higher in ENP male dolphins (LFK: 2936.0 ng.g-1 dw, ENP: 10048.3 ng.g-1 dw). These high concentrations were the highest recorded in the south-eastern US and are most likely due to the presence of mangrove ecosystems. This study highlights the complexity of contaminant dynamics (inorganic vs. organic), even at small spatial scales. [less ▲]
