Résumé : International audience
In order to perform a human and ecological risk assessment of pharmaceutical products (PPs) in natural waters, it is necessary to accurately quantify a broad variety of PPs at low concentrations. Although numerous currently implemented analytical methodologies, less is known about the preservation of PPs in natural water samples within the period before analysis (holding time, storage conditions). This paper is the first literature review about the stability of PPs in natural waters (surface and groundwaters) during sample storage. The current work focuses on a comparison of the performances of the available preservation techniques (filtration, container materials, storage temperature, preservative agents, etc.) for PPs in samples. All 58 reviewed PPs may be successfully stabilized during 7 days in surface waters by at least one appropriate methodology regarding temperature, acidic and non-acidic preservatives. When temperature is not a sufficient preservation parameter f! or some PPs (hormones and fluoxetine) its combination with the addition of chemical agents into the samples may prolong the integrity of the PPs during storage in surface water. There is a strong need to use standard protocols to assess and compare the stability of PPs in environmental water matrices during storage as well as during analytical preparation or analysis (European criteria 2002/657/EC). Since the stability of PPs during sample storage is a critical parameter that could call into question the quality of the data provided for the concentrations, the design of stability studies should rigorously take into account all critical parameters that could impact the concentrations of the PPs with time.

Résumé : L’histoire du tourisme international des cinquante dernières années peut être décomposée en trois temps : 1/ les décennies de 1950 à 1980, caractérisées par une démocratisation progressive du tourisme soutenue par une croissance économique inégalée ; 2/ la dernière décennie du vingtième siècle, celle d’une euphorie touristique qui voit les frontières s’ouvrir. La fin d’un monde bipolaire annonce bien des espoirs naïfs. Le champ des territoires ouverts au tourisme ne cesse de s’élargir. 3/ La fin du siècle annonce l’âge de maturité du tourisme. Après l’euphorie, les illusions et les désillusions d’un espace touristique mondial sans frontières, les faits, souvent dramatiques ont fait prendre conscience aux touristes la complexité d’un monde où les guerres n’ont jamais cessé. L’espace touristique mondial est articulé autour de trois bassins régionaux : plus de 75 % des flux touristiques internationaux, impulsés par les riches métropoles européennes, nord-américaines et asiatiques, se cantonnent à dans leur espace régional d’origine. La distribution des flux touristiques dessine une organisation en trois bassins distincts : par ordre d’importance, 1/ le bassin euro-méditerranéen, centré sur la Mer méditerranée, 2/ le bassin Asie orientale-Pacifique, autour des rivages de la mer de Chine, 3/ le bassin Amérique du Nord — Caraïbes, organisé autour de la « Méditerranée américaine ». Les discontinuités s’affirment entre des périphéries mal stabilisées, des prolongements très sélectifs, des marges oubliées ou exclues. Les climats d’insécurité qui touchent certains territoires touristiques visent à fragiliser des périphéries plus sensibles et contraignent l’espace touristique international à se rétracter.
The history of international tourism of the last fifty years can be divided into three stages: 1 / decades from 1950 to 1980, characterized by a progressive democratization of tourism supported by an unparalleled economic growth, 2 / the last decade of the twentieth century, euphoria of a tourist who sees the borders open. The end of a bipolar world announcement many hopes naive. The scope of territories open to tourism continues to widen. 3 / The end of the century announces the age of maturity of tourism. After the euphoria, illusions and disillusions of a space tourist world without borders, facts, often dramatic raised awareness tourists to the complexity of a world where wars have never ceased. The global space tourism is articulated around three regional basins: more than 75% of international tourist flows, driven by the rich European cities, North American and Asian, are confined to their regional area of origin. The distribution of tourist flows draws an organization into three distinct basins: in order of importance, 1 / Euro-Mediterranean basin, focusing on the Mediterranean Sea, 2 / Basin East Asia-Pacific, around the shores of the Sea of China, 3 / basin North America-Caribbean, organized around the "American Mediterranean." Space discontinuities increase between peripheries unstable, extensions selective and margins forgotten or excluded. The climate of insecurity that affect certain touristic territories aimed at weakening the outskirts most sensitive and oblige the international space tourist to retract.

Résumé : International audience
Background: Infant exposure to persistent organic pollutants (POPs) may contribute to obesity. However, many studies so far have been small, focused on transplacental exposure, used an inappropriate measure to assess postnatal exposure through breastfeeding if any, or did not discern between prenatal and postnatal effects.Objectives: We investigated prenatal and postnatal exposure to POPs and infant growth (a predictor of obesity).Methods: We pooled data from seven European birth cohorts with biomarker concentrations of polychlorinated biphenyl 153 (PCB-153) (n = 2,487), and p,p´-dichlorodiphenyldichloroethylene (p,p´-DDE) (n = 1,864), estimating prenatal and postnatal POPs exposure using a validated pharmacokinetic model. Growth was change in weight-for-age z-score between birth and 24 months. Per compound, multilevel models were fitted with either POPs total exposure from conception to 24 months or prenatal or postnatal exposure.Results: We found a significant increase in growth associated with p,p´-DDE, seemingly due to prenatal exposure (per interquartile increase in exposure, adjusted β = 0.12; 95% CI: 0.03, 0.22). Due to heterogeneity across cohorts, this estimate cannot be considered precise, but does indicate that an association with infant growth is present on average. In contrast, a significant decrease in growth was associated with postnatal PCB-153 exposure (β = –0.10; 95% CI: –0.19, –0.01).Conclusion: To our knowledge, this is the largest study to date of POPs exposure and infant growth, and it contains state-of-the-art exposure modeling. Prenatal p,p´-DDE was associated with increased infant growth, and postnatal PCB-153 with decreased growth at European exposure levels.

Résumé : International audience
This paper reports the first outcomes of a research program “Environment and Sustainable Development in the Caribbean space” co-funded by the European Union, the Région Martinique and the Université des Antilles et de la Guyane under the European Union operational programme 2007-2013. Since the middle of the last century, the Caribbean countries, regardless of their great diversity and political fragmentation, are faced with the recurring problem of development. Having explored different paths, they are looking now for new development models. This challenge which becomes obsessive over the decades, is now a major concern: indeed, the Caribbean territories are per se vulnerable and highly exposed to natural risks due to climate change. In addition, this relates to areas where tensions between exploitation and conservation of a rich biodiversity are particularly strong. Based on the promotion of tourism and services as part of an “open regionalism” at the intersection of global and local scales of public action, the current development strategies give rise to a dual approach with, however, rather mixed results: on the one hand, a discursive use of sustainable development, apprehended through its environmental dimension, evidences a new way of looking at the region and a change in the way the region sees itself; on the other hand, a political use of sustainable development through cross-cutting policies, is hindered by the complexity of structures, the multiple levels of action and regulation, and the difficult appropriation of public-policy organization by local communities and people.
Cet article rend compte des premiers résultats d’un programme de recherche « Environnement et développement durable dans l’espace caraïbe » cofinancé par l’Union européenne, la région Martinique et l’Université des Antilles et de la Guyane dans le cadre des programmes opérationnels européens 2007-2013. Il montre que les territoires de la Caraïbe, après avoir exploré plusieurs voies en matière de développement, privilégient désormais des stratégies axées sur le tourisme et les services. S’inscrivant dans un « régionalisme ouvert » au croisement des échelles globale et locale d’intervention en matière d’action publique, ces stratégies débouchent sur une double démarche aux résultats contrastés : d’un côté, une mise en discours du développement durable, appréhendé notamment à travers sa dimension environnementale, témoigne d’un changement de regard sur la région et de celle-ci sur elle-même ; de l’autre, une mise en politique du développement durable à travers des dispositifs à caractère transversal, se heurte à la complexité des structures, à la multiplicité des échelles d’intervention et de régulation ainsi qu’à la difficile appropriation desdits dispositifs par les populations locales.

Résumé : Integrated Ocean Drilling Program (IODP) Expedition 325, designed to investigate the fossil reefs on the shelf edge of the Great Barrier Reef, was the fourth expedition to utilize a mission-specific platform and was conducted by the European Consortium for Ocean Research Drilling (ECORD) Science Operator (ESO). The objectives of Expedition 325 were to establish the course of sea level change, define sea-surface temperature variations, and analyze the impact of these environmental changes on reef growth and geometry for the region over the period of 20-10 ka. To meet these objectives, a succession of fossil reef structures preserved on the shelf edge seaward of the modern barrier reef were cored from a dynamically positioned vessel in February-April 2010. A total of 34 boreholes across 17 sites were cored in depths ranging from 42.27 to 167.14 meters below sea level (lowest astronomical tide taken from corrected EM300 multibeam bathymetry data). Borehole logging operations in four boreholes provided continuous geophysical information about the drilled strata. The cores were described during the Onshore Science Party (OSP) at the IODP Bremen Core Repository (Germany) in July 2010, where minimum and some standard measurements were made. Preliminary postcruise dating of core catcher samples and initial observations of the cores made during the OSP confirm that coral reef material ranging in age from >30,000 to 9,000 calendar years before present (years before 1950 AD) was recovered during Expedition 325. Further postcruise research on samples taken during the OSP is expected to fulfill the objectives of the expedition.

Résumé : International audience
The aim of the present study was to determine the effects of 40 km of cycling on the biomechanical and cardiorespiratory responses measured during the running segment of a classic triathlon, with particular emphasis on the time course of these responses. Seven male triathletes underwent four successive laboratory trials: (1) 40 km of cycling followed by a 10-km triathlon run (TR), (2) a 10-km control run (CR) at the same speed as TR, (3) an incremental treadmill test, and (4) an incremental cycle test. The following ventilatory data were collected every minute using an automated breath-by-breath system: pulmonary ventilation VE, l x min[-1]), oxygen uptake (VO2, ml x min(-1) x kg[-1]), carbon dioxide output (ml x min[-1]), respiratory equivalents for oxygen (VE/VO2) and carbon dioxide (VE/VCO2), respiratory exchange ratio (R) respiratory frequency (f, breaths x min[-1]), and tidal volume (ml). Heart rate (HR, beats x min[-1]) was monitored using a telemetric system. Biomechanical variables included stride length (SL) and stride frequency (SF) recorded on a video tape. The results showed that the following variables were significantly higher (analysis of variance, P < 0.05) for TR than for CR: VO2 [51.7 (3.4) vs 48.3 (3.9) ml x kg(-1) x min(-1), respectively], VE [100.4 (1.4) l x min(-1) vs 84.4 (7.0) l x min(-1)], VE/VO2 [24.2 (2.6) vs 21.5 (2.7)] VE/VCO2 [25.2 (2.6) vs 22.4 (2.6)], f[55.8 (11.6) vs 49.0 (12.4) breaths x min(-1)] and HR [175 (7) vs 168 (9) beats x min(-1)]. Moreover, the time needed to reach steady-state was shorter for HR and VO2 (1 min and 2 min, respectively) and longer for VE (7 min). In contrast, the biomechanical parameters, i.e. SL and SF, remained unchanged throughout TR versus CR. We conclude that the first minutes of the run segment after cycling in an experimental triathlon were specific in terms of VO2 and cardiorespiratory variables, and nonspecific in terms of biomechanical variables.

Résumé : Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of management-oriented indicators, integrating management questions and performance criteria. We first examined the desirable characteristics of indicators aimed at providing decision-support for marine environmental management. Ideally, one should select the indicator that guarantees a safe and unambiguous decision leading to the appropriate measures in terms of regulation, remediation or control. In the present study, indicators are assessed according to two criteria: relevance and effectiveness. Relevance encompasses sensitivity and the existence of quantitative reference values, thereby allowing the selection of potential indicators. Effectiveness is the ability of the indicator to reach its predefined targets based on optimal (or at least improved) data collection protocols. The framework is illustrated by applying it to the European Water Framework Directive and to the Marine Protected Area management contexts. (C) 2010 Elsevier Ltd. All rights reserved.

Résumé : International audience
Previous studies have reported respiratory, cardiac and muscle changes at rest in triathletes 24 h after completion of the event. To examine the effects of these changes on metabolic and cardioventilatory variables during exercise, eight male triathletes of mean age 21.1 (SD 2.5) years (range 17-26 years) performed an incremental cycle exercise test (IET) before (pre) and the day after (post) an official classic triathlon (1.5-km swimming, 40-km cycling and 10-km running). The IET was performed using an electromagnetic cycle ergometer. Ventilatory data were collected every minute using a breath-by-breath automated system and included minute ventilation (V(E)), oxygen uptake (VO2), carbon dioxide production (VCO2), respiratory exchange ratio, ventilatory equivalent for oxygen (V(E)/VO2) and for carbon dioxide (V(E)/VCO2), breathing frequency and tidal volume. Heart rate (HR) was monitored using an electrocardiogram. The oxygen pulse was calculated as VO2/HR. Arterialized blood was collected every 2 min throughout IET and the recovery period, and lactate concentration was measured using an enzymatic method. Maximal oxygen uptake (VO2max) was determined using conventional criteria. Ventilatory threshold (VT) was determined using the V-slope method formulated earlier. Cardioventilatory variables were studied during the test, at the point when the subject felt exhausted and during recovery. Results indicated no significant differences (P > 0.05) in VO2max [62.6 (SD 5.9) vs 64.6 (SD 4.8) ml x kg(-1) x min(-1)], VT [2368 (SD 258) vs 2477 (SD 352) ml x min(-1)] and time courses of VO2 between the pre- versus post-triathlon sessions. In contrast, the time courses of HR and blood lactate concentration reached significantly higher values (P < 0.05) in the pre-triathlon session. We concluded that these triathletes when tested 24 h after a classic triathlon displayed their pre-event aerobic exercise capacity, bud did not recover pretriathlon time courses in HR or blood lactate concentration.

Résumé : International audience
Bronchoalveolar lavage (BAL) is a major diagnostic tool in lung diseases, including viral respiratory infections. We aimed to better define the situations where viral tests should be performed on BAL fluid (BALF). We retrospectively studied all cases where viral tests [immunofluorescence, immunocytochemistry, viral culture, and/or polymerase chain reaction (PCR)] were performed on BALF during a period of 1 year (2008) in our institution. We compared the characteristics of patients with virus-positive versus virus-negative BALF. Of the 636 BALF samples sent to the microbiology laboratory, 232 underwent viral tests. Of these, 70 (30 %) were positive and identified 85 viruses: herpes simplex virus (HSV)-1 (n = 27), cytomegalovirus (CMV, n = 23), Epstein-Barr virus (EBV, n = 18), human herpesvirus (HHV)-6 (n = 12), respiratory syncytial virus (RSV, n = 3), rhinovirus (n = 1), and adenovirus (n = 1). The variables associated with positive viral tests on univariate analysis were immunosuppression [human immunodeficiency virus (HIV), corticosteroids >10 mg/day for ≥3 weeks, or other immunosuppressive therapy], ground-glass attenuations on computed tomography (CT) scanning, late-onset ventilator-associated pneumonia (VAP), and durations of (i) hospital stay, (ii) intensive care unit (ICU) stay, and (iii) mechanical ventilation before BAL (p < 0.01 for each comparison). On multivariate analysis, only immunosuppression [odds ratio (OR) 6.4, 95 % confidence interval (CI) [2.8-14.3], p < 0.0001] and ground-glass attenuations (OR 3.7, 95 % CI [1.8-7.7], p = 0.0004) remained associated with virus-positive BAL. None of the viral tests performed on BALF for the initial assessment of diffuse infiltrative lung disease (n = 15) was positive. PCR improved the diagnostic yield of viral tests on BALF by 50 %. Testing for viruses on BALF should be mostly restricted to immunocompromised patients with acute respiratory diseases and/or patients with unexplained ground-glass attenuations on CT scanning.

Résumé : International audience
This study provides new Ar-40/Ar-39 geochronological constraints on the age of the Alpine tectonics in the Aspromonte Massif (southern part of the Calabrian-Peloritan belt). This massif exposes the upper units of the Calabride Complex which originated from the European continental margin. The Calabride Complex was incorporated in the Alpine orogenic wedge and then integrated into the Apennines and Maghrebides fold- and-thrust belts. Throughout the Calabride Complex there is evidence for a two stage tectonic history, which remains however rather poorly dated: Alpine nappe stacking is followed by extensional reworking along the former thrust contacts or along new detachment surfaces. Our new ages suggest that exhumation of the uppermost units, which accompanied nappe stacking, probably started at 45 Ma and that the deepest units were almost completely exhumed at 33 Ma. This kinematics probably corresponds to syn-orogenic extension while the end of exhumation is clearly related to the extensional tectonics dated at 28.6 Ma along detachment structures.;Our geochronological data reveal a very short lag time between accretional and extensional processes in this part of the Mediterranean Alpine orogenic belt. The direction of extension, when the units are restored to their initial position (i.e. before the opening of the Western Mediterranean basins and the bending of the arc) is NNE-SSW. Such a direction does not fit with the eastward slab-retreat model generally put forward to explain extension in the Western Mediterranean. In contrast, we provide evidence for roughly N-S middle Oligocene extension in the accretionary prism, not previously described in this part of the Mediterranean domain.

Résumé : Mediterranean aquaculture development is now at a crossroads. The production of seabass and seabream has been increasing at a smart and constant pace for the last ten years. Nevertheless, it is still far behind the Northern European salmonid industry in terms of level of production, reduction of production costs and market internationalisation. Meanwhile, an in depth transformation of market conditions is ongoing in Europe which remains the main target market for Mediterranean aquaculture products. The most important issues are the soaring role of supermarkets in the distribution chain, the development of new processing techniques like pre-packed fresh fish, the growing importance of catering and the evolution of the consumer behaviour. Seafood consumer behaviour results from contradictory attitudes such as scrutiny of products' origin and farming process, research of the best value for money, desire of social image and need for easy to store and ready to cook fish. As in any other seafood industry, product differentiation has become a pre-requisite to fit consumer's demand and reach new consumers thanks to market segmentation. From a theoretical point of view, two kinds of differentiation have to be taken into account: horizontal differentiation basedon the diversity of presentations of the same quality and vertical differentiation based on a hierarchy of quality. Examining precedents in the poultry industry and salmonid industry make it possible to assess the potential role new species may play in product differentiation. In the case of Mediterranean aquaculture, an analysis of the market structure for fresh fish in France, Italy and Greece reveals two different ways of product differentiation: new well known species with a good image for connoisseur markets and standard quality fish provided by species with high growth potential for the mass market. In any case, particular attention has to be given to reputation, long term production costs and capacity to provide a large range of products. [NOT CONTROLLED OCR]

Résumé : A new method is developed to estimate daily turbulent airsea fluxes over the global ocean on a 0.25 degrees grid. The required surface wind speed (w(10)) and specific air humidity (q(10)) at 10m height are both estimated from remotely sensed measurements. w(10) is obtained from the SeaWinds scatterometer on board the QuikSCAT satellite. A new empirical model relating brightness temperatures (T-b) from the Special Sensor Microwave Imager (SSM/I) and q(10) is developed. It is an extension of the author's previous q(10) model. In addition to T-b, the empirical model includes sea surface temperature (SST) and airsea temperature difference data. The calibration of the new empirical q(10) model utilizes q(10) from the latest version of the National Oceanography Centre airsea interaction gridded data set (NOCS2.0). Compared with mooring data, the new satellite q(10) exhibits better statistical results than previous estimates. For instance, the bias, the root mean square (RMS), and the correlation coefficient values estimated from comparisons between satellite and moorings in the northeast Atlantic and the Mediterranean Sea are 0.04gkg(1), 0.87gkg(1), and 0.95, respectively. The new satellite q(10) is used in combination with the newly reprocessed QuikSCAT V3, the latest version of SST analyses provided by the National Climatic Data Center (NCDC), and 10m air temperature estimated from the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalyses (ERA-Interim), to determine three daily gridded turbulent quantities at 0.25 degrees spatial resolution: surface wind stress, latent heat flux (LHF), and sensible heat flux (SHF). Validation of the resulting fields is performed through a comprehensive comparison with daily, in situ values of LHF and SHF from buoys. In the northeast Atlantic basin, the satellite-derived daily LHF has bias, RMS, and correlation of 5Wm(2), 27Wm(2), and 0.89, respectively. For SHF, the statistical parameters are 2Wm(2), 10Wm(2), and 0.94, respectively. At global scale, the new satellite LHF and SHF are compared to NOCS2.0 daily estimates. Both daily fluxes exhibit similar spatial and seasonal variability. The main departures are found at latitudes south of 40 degrees S, where satellite latent and sensible heat fluxes are generally larger.

Résumé : International audience
ABSTRACT: Environmental exposures during pregnancy and early life may have adverse health effects. Single birth cohort studies often lack statistical power to tease out such effects reliably. To improve the use of existing data and to facilitate collaboration among these studies, an inventory of the environmental exposure and health data in these studies was made as part of the ENRIECO (Environmental Health Risks in European Birth Cohorts) project. The focus with regard to exposure was on outdoor air pollution, water contamination, allergens and biological organisms, metals, pesticides, smoking and second hand tobacco smoke (SHS), persistent organic pollutants (POPs), noise, radiation, and occupational exposures. The review lists methods and data on environmental exposures in 37 European birth cohort studies. Most data is currently available for smoking and SHS (N=37 cohorts), occupational exposures (N=33), outdoor air pollution, and allergens and microbial agents (N=27). Exposure modeling is increasingly used for long-term air pollution exposure assessment; biomonitoring is used for assessment of exposure to metals, POPs and other chemicals; and environmental monitoring for house dust mite exposure assessment. Collaborative analyses with data from several birth cohorts have already been performed successfully for outdoor air pollution, water contamination, allergens, biological contaminants, molds, POPs and SHS. Key success factors for collaborative analyses are common definitions of main exposure and health variables. Our review emphasizes that such common definitions need ideally be arrived at in the study design phase. However, careful comparison of methods used in existing studies also offers excellent opportunities for collaborative analyses. Investigators can use this review to evaluate the potential for future collaborative analyses with respect to data availability and methods used in the different cohorts and to identify potential partners for a specific research question.

Résumé : The method of shear-wave splitting provides a unique possibility to identify seismic anisotropy, which is a result of the preferred orientations of the anisotropic minerals by deformation. The novel software SplitLab, presented in this thesis, simplifies the data processing. The comparison of three independent techniques makes it possible to associate an objective quality to the results and also to define a criterion to automatically detect events without splitting (“Nulls”). This criterion is applied to shear-wave splitting measurements at 16 stations located on the East European Craton. The results indicate that the fast directions reflect the ancient blocks, which constitute the East European Craton. The fast directions in south-west are aligned with the margin of the craton and continue the general tendency of offcraton stations. The stations in the Ural foredeep show fast directions perpendicular to the general tendency of the mountain chain. Various indicators give reason to assume lithospheric origins of anisotropy
La mesure du déphasage des ondes de cisaillement offre la possibilité de caractériser l'anisotropie sismique présente dans les différentes couches de la Terre, qui résulte généralement des orientations préférentielles des minéraux anisotropes induites par la déformation. Le nouveau logiciel SplitLab présenté dans cette thèse, simplifie le traitement des données depuis la requête des données jusqu'à la masure de déphasage et l'interprétation des résultats. La comparaison de trois techniques indépendantes pour mesurer ce déphasage permet de quantifier la qualité des résultats et de détecter automatiquement les mesures sans déphasage apparent. Ce critère est appliqué aux mesures de déphasages des ondes SKS enregistrées en 16 stations situées sur le Craton Est Européen. Les résultats indiquent que les directions rapides reflètent les structures anciennes, qui constituent le Craton Est Européen. En outre, les directions rapides dans le Sud-ouest s'alignent avec la bordure du craton et sont en continuité avec la tendance générale définie par les stations éloignées du Craton. Les stations dans les unités externes de l'Oural montrent des directions rapides perpendiculaires à la tendance générale de la chaîne de montagne.

Résumé : The Var turbiditic system located in the Ligurian Sea (SE France) is an intermediate mud/sand-rich system. The particularity of the Var deep-sea fan is its single channel with abrupt bends and its asymmetric and hyper-developed levee on the right hand side: the Var Sedimentary Ridge. Long-term sediment accumulation on the Var Sedimentary Ridge makes this an ideal target for studying the link between onshore climate change and deep-sea turbidite stratigraphy. This paper focuses on the establishment of the first detailed stratigraphy of the levee, which is used to analyze the timing of overbank deposition throughout the last deglaciation. Main results indicate that high variability in turbidite frequencies and deposition rates along the Var Sedimentary Ridge are determined by two main parameters: 1) the progressive decrease of the levee height controlling the ability of turbidity currents to spill out from the channel onto the levee, and 2) climatic variations affecting the drainage basin, in particular changes in glacial condition since late Last Glacial Maximum to early Holocene. Compared to other deep-water areas, this study confirms the ability of turbiditic systems to record past climatic events on millennial timescales, and underlines the influence of European deglaciation on the observed decrease in turbidite activity in the Var canyon. The presence of a very narrow continental shelf and a single, large channel-levee system makes the Var Sedimentary Ridge a unique example of climate-controlled turbiditic accumulations.

Résumé : International audience
The description of the Common European Framework for Languages still varies from a country to another one, nvertheless it is based on seemingly to unambiguous formulations as "Can manage in the situations of the everday life" (CEFRL:66). Ths paper analyzes the methodes of design and the theorical, symbolic and systemic limits of scales, and it tries to define why the establishment of a set of common reference points for languages doesn't reach its goal of a consensual interpretation of the Common Reference Levels.
Nous explorons dans cet article les modalités de conception, les limites théoriques, symboliques et systémiques des échelles de compétence en langue du Cadre européen commun de référence pour les langues, afin de répondre à une question en apparence simple. Pourquoi les spécifications du Cadre, pourtant définies sur la base de descripteurs en apparence aussi univoques que "Peut se débrouiller dans les situations de la vie quotidienne" (Cadre:66) varient-elles autant d'un pays à l'autre ou d'une méthode FLE à l'autre?

Résumé : International audience
A feasibility study of glulam was carried out in French Guiana using local wood species. The aim was to determine gluing parameters affording satisfactory behaviour to manufactured glulam in a tropical climate. Three abundant wood species, with special properties, were selected for the study and Resorcinol-Phenol-Formaldehyde resin was used for bonding. Three industrial parameters were considered: adhesive spread rate, closed assembly time and gluing pressure. Delamination and shearing tests were carried outin accordance with European Standards. The tests revealed the influence of wood properties and manufacturing parameters on joint resistance. In fact, the results showed that specific gravity and the shrinkage coefficientgreatly influenced the gluing step. Indeed, wood with a medium specific gravity needed more adhesive and more pressure than wood with a high specific gravity. In addition, planning and lamella thicknesswere found to affect glue joint resistance.

Résumé : Le territoire d’Aysen, au sud du Chili, officiellement dénommé « Région XI », possède le charme discret d’une Patagonie oubliée. Cette région mythique n’a cessé de hanter l’imaginaire fécond des découvreurs et voyageurs en tout genre. Aujourd’hui, ces derniers sont autant des pêcheurs à la mouche fortunés que des routards européens ou israéliens, et de plus en plus des Chiliens venus des classes moyennes et du nord du pays. La Patagonie est un formidable terrain de jeu, et plus encore un vaste espace d’utopie, hier comme aujourd’hui, pour nombre de voyageurs et rêveurs.Le « charme » est indéniable, il suffit de contempler la nature qui domine ici la culture, et la région n’est pas un paradis pour les photographes par hasard ; quant au caractère « discret », il est également évident, comme en témoignent de nombreux touristes en quête de leur propre expérience “into the wild” et qui s’émerveillent en foulant ces sentiers non battus de la Patagonie. Terre de jeu pour aventuriers, lieu de science pour les chercheurs, espace de refuge pour de riches expatriés, territoire d’expérimentation sinon de rite de passage pour quelques jeunes et sportifs, marcheurs, cyclistes ou flâneurs, la Patagonie chilienne est désormais surtout devenue un enjeu, économique et donc politique, essentiel pour le pays.Cet article, fruit d’un travail en cours, apporte quelques éléments pour tenter de comprendre comment se fabrique et s’établit, dans le temps et dans l’espace, « une destination non touristique » qui, depuis ces dernières années, à la faveur des médias, mais pas seulement, a le vent en poupe. Avec ou sans le consentement des Patagons/Patagoniens ? C’est tout le véritable défi à venir.
The territory of Aysen in southern Chile, officially called "Region XI" has the discreet charm of a forgotten Patagonia. This legendary region has haunted the fertile imagination of explorers and travelers of all kinds. Today, they are so many rich fly fishermen that European or Israeli backpackers, and always more Chileans coming from the middle class and from the north of the country. Patagonia is a wonderful playground, and even more a vast space of utopia, then as now, for many travelers and dreamers.The "charm" is undeniable, simply contemplate the fabulous nature clearly dominating culture here, and the area is not a paradise for photographers by chance. As to the character "discrete", it is also clear, as evidenced by many tourists in search of their own experience "into the wild" and marvel treading the beaten path not of Patagonia. Playground for adventurers, place of science for researchers, refuge area for fortunate expatriates testing ground if not some rite of passage for young athletes, walkers, cyclists or loafers, Chilean Patagonia is now mostly become an issue, and therefore economic policy, rather essential for the country.This article, the first result of a work in progress, brings some elements to try to understand how to manufacture and settled in time and space, "a non-tourist destination", which, in recent years, the for the media but not only has the wind in its sails. With or without the consent of all the habitants of Patagonia? This is the real challenge ahead.
