Understanding the natural heterogeneity of coral zooxanthellae density appears as very important to understand variations in coral survival due to bleaching (the loss of these micro-algal symbionts). Heterogeneity of coral bleaching at different observation scales (within a colony, among neighbouring colonies of the same species or on a wider scale) remains largely misunderstood. The present work explores intracolonial, spatial and temporal variations of zooxanthellae density in the coral Acropora globiceps Dana 1846, over a period of three months on the forereef of Moorea, French Polynesia. In our study, intracolonial zooxanthellae densities did not vary significantly. However, zooxanthellae densities differed slightly between inner and outer branches but this trend was not significant at 6, 12 and 18 meters depth. On a wider scale, zooxanthellae densities also vary spatially : a positive correlation was observed between depth and symbiont density (density increases when light intensity decreases, so according to depth). Moreover, the location of colonies exposed to different hydrodynamical conditions was not a parameter controling the concentration of zooxanthellae. Finally, the temporal variation of zooxanthellae densities did not show significant variations even if it decreased slightly over the study period. The results of this study highlight the importance of accounting for variations within and among colonies to determine zooxanthellae densities and to assess the evolution of zooxanthellae populations.

The tuned mass damper (TMD) is a simple and efficient device, but it is only effective when it is precisely tuned to the frequency of a vibration mode. Because nonlinear vibrating structures have resonant frequencies that vary with the amount of total energy in the system, the efficiency of a TMD is questionable in this case. In the present study, the performance of an essentially nonlinear attachment, termed a nonlinear energy sink (NES), is assessed. It is shown that, unlike the TMD, an NES has no preferential resonant frequency, which makes it a good candidate for vibration mitigation of nonlinear vibrating structures. [less ▲]

Very little is known about primate reintroduction projects in Mesoamerica. The aim of this study was to focus on existing projects concerning primate re-introductions, conservation-introduction, translocation, as well as on reinforcement-supplementation of parallel initiatives. In order to create a database, a survey was sent to a panel of scientists in Mexico, Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama, and we visited five projects in Costa Rica from March to August 2006. A total of 19 projects were found: Costa Rica hosted the higher number (7) while Salvador and Nicaragua did not host any. Fourteen out of those 19 projects concerned confiscated animals. Six of the 7 Costa Rican projects used confiscated primates; the other ones came from wild populations or were born in captivity. Alouatta palliata and Ateles geoffroyi are the most common species subject to reintroduction effort in the Mesoamerican region. A wide range of factors seem to influence reintroduction success such as: the project’s budget, the release site, the mode of transportation, the caging setting, the support from local communities, the presence of environmental education programs, but also the age of primates, etc. Each project seems to work as a completely separated entity, with its own definition of reintroduction success and its own policy. There’s no communication between the projects, no matter if they are based in the same country or work on the same species. A reintroduction guideline for this region should be established as well as a regional network coordinating the information. [less ▲]

The European project SESAME (Southern European Seas: Assessing and Modelling Ecosystem changes) is dedicated to the assessment of ecological changes in the Mediterranean and Black seas during these last decades. This assessment will be done by combining statistical analysis of available data and the development of a 3D hydrodynamical-biogeochemical model. Data available since 1960 for the Black Sea from the databases MEDAR and NATO have been completed with data provided by SESAME partners. These data sets have been analyzed using DIVA, a geostatistical analysis tool developed by the GHER laboratory of the University of Liège. The DIVA analysis relies on a finite element resolution, taking into account coastlines, sub-basins, and advection by ocean currents. DIVA analysis generates spatially interpolated fields for biogeochemical and physical variables. Outputs consist in sets of analysis as well as error fields, and colorimetric scaled maps related to several depth layers. Biogeochemical variables considered consist in measures of chlorophyll, inorganic nutrients concentration, and phytoplankton abundances; physical variables consist in temperature and salinity. These treatments of the Black sea data sets offer an overview of the global pattern of the Black sea biogeochemical structure, and its evolution through the time periods concerned by the project. The interpolated fields generated by the DIVA tool will be used to validate the outputs of the 3D hydrodynamical-biogeochemical model developed for the north-western shelf of the Black sea in the framework of SESAME.

Objectif Mettre au point une épreuve de quantification de l'activité physique journalière de la population générale en vue, d'une part, d'envisager des mesures préventives en matière de promotion de la santé et, d'autre part, d'établir des données normatives confrontables à celles de populations souffrant d'affections diverses (ostéo-articulatoires, rhumatologiques, chroniques, … ). Patients et Méthodes La population étudiée comporte 84 sujets volontaires sains, âgés de 20 à 80 ans et répartis en classe d'âge par décade. Le monitoring d'activité physique est réalisé durant 24 heures à partir du Sense Wear® Armband (composé d'un accéléromètre et de capteurs thermiques) porté au niveau du bras en l'absence de toute gêne particulière. Ce dispositif enregistre sur une période de 24 heures la dépense énergétique totale (Kcal), le nombre de pas, l'intensité moyenne d'effort en équivalent métabolique (MET), ainsi que la dépense énergétique réalisée à différents niveaux d'intensité d'activités physiques : 0 à 1 MET, 1 à 2 MET, 2 à 3 MET, > à 3 MET, > à 6 MET, … Les sujets sont en outre soumis au « Minnesota Leisure Time Physical Activity Questionnaire » (MLTPAQ). Résultats Nous observons une réduction significative de la dépense énergétique enregistrée durant 24 heures avec l'augmentation de l'âge. La classe d'âge 31-40 ans semble la plus dynamique comme en atteste l'intensité moyenne d'effort sur 24 h (1,7 MET), la dépense énergétique enregistrée lors d'activités supérieures à 6 MET et le nombre de pas parcourus sur 24 h. De façon originale, nous constatons que la dépense énergétique pour des activités comprises entre 0 et 1 MET augmente significativement avec l'âge alors que le phénomène inverse apparaît pour les activités supérieures à 6 MET. Un constat alarmant concerne le manque d'activités physiques actives (supérieures à 3 MET) constaté au sein de la population générale. Des corrélations significatives s'observent entre les différents paramètres enregistrés à partir du Sense Wear® Armband et diverses données issues du questionnaire MLTPAQ. Discussion L'établissement de données normatives en termes d'activités physiques journalières à partir de ce protocole original s'avère particulièrement pertinent dans le cadre du suivi fonctionnel de la population générale mais aussi de multiples populations pathologiques. Conclusion La poursuite de ces recherches dégage des perspectives en vue de la mise en place de mesures préventives en matière de promotion de la santé mais aussi dans la caractérisation du statut fonctionnel ou encore le suivi longitudinal d'un patient souffrant d'affections diverses.

Substituting a heat pump to a boiler may save more than 50% of primary energy, if electricity is produced by a modern combined cycle power plant (and even more if a part of that electricity is produced using renewable sources). Two of the most attractive heat pumps applications consist in recovering the heat rejected by the condenser of an existing chiller and in using this chiller in reversible mode. This is the topic of the IEA-ECBCS Annex 48 project (“Heat pumping and reversible air conditioning”). An overview of the project is presented and the work of the different participants is briefly explained. Case studies are also briefly presented and more details are given on one of them. [less ▲]

redictions of sound propagation in urban areas have attracted a considerable over the years. If the sound energy is assimilated to particles with a constant energy, their movement can be described by a transport equation. In canyon streets, this transport equation can be reduced to a diffusion equation whose expression is more simple. In this presentation, sound absorption at the boundaries (buildings facades and ground), as well as atmospheric sound attenuation are introduced. The problem is then solved numerically using a finite elements method for the configuration of a canyon street. A systematic validation of the obtained model is carried out in terms of sound pressure level by comparison to numerical simulations taken from the literature. Comparisons with experimental data are then conducted. Finally, applications in more complex configurations are presented. [less ▲]

OBJECTIVE: An effective and well tolerated intravenous (IV) bisphosphonate could provide a new treatment method for patients with osteoporosis. The Dosing IntraVenous Administration (DIVA) study was designed to identify the optimal ibandronate IV injection schedule for the treatment of postmenopausal osteoporosis by comparing the efficacy and tolerability of 2- and 3-monthly injections with the previously evaluated daily oral ibandronate regimen. We report the effects on lumbar spine and proximal femur bone mineral density (BMD) and bone resorption markers over 2 years. METHODS: This randomized, double-blind, double-dummy, noninferiority study recruited 1395 women (aged 55-80 yrs; > or = 5 yrs since menopause) with osteoporosis [mean lumbar spine (L2-L4) BMD T-score < -2.5 and > or = -5.0]. Patients received IV ibandronate (2 mg every 2 mo or 3 mg every 3 mo) plus daily oral placebo, or 2.5 mg daily oral ibandronate plus 2- or 3-monthly IV placebo. Supplemental vitamin D (400 IU) and calcium (500 mg) were provided throughout the 2-year study. RESULTS: At 2 years, the 2- and 3-monthly IV regimens achieved statistically noninferior and also superior increases in lumbar spine BMD compared with the daily regimen (6.4% and 6.3% vs 4.8%, respectively; p < 0.001). Greater increases were also obtained with IV ibandronate versus daily in proximal femur BMD. Serum concentrations of the biochemical marker of bone resorption C-telopeptide of the alpha-chain of type I collagen were reduced to a similar extent in all treatment arms (53.4%-59.9%). The tolerability profile of the IV regimens was similar to that observed with daily oral therapy. CONCLUSION: Ibandronate IV injections are an effective and well tolerated treatment for postmenopausal osteoporosis and provide a useful alternative to oral dosing. [less ▲]

Hazard analysis of dams arranged in complex or in cascade may involve the assessment of a large number of different scenarios of combined failures. However, a tremendous computation time would be needed to perform a detailed modeling of the flows generated by all possible scenarios. Therefore, the present paper describes a rational methodology for analyzing the flows induced by the most relevant incidents occurring on a complex or in a cascade of dams and reservoirs. The methodology combines several hydrodynamic models, including the twodimensional flow solver WOLF 2D and a simplified lumped hydrodynamic model, to simulate (i) the flows induced on the dams complex, (ii) the potential breaching in cascade of other dams, as well as (iii) the propagation of the flood wave in the whole downstream valley. The application of the methodology to a practical case study involving a complex of five dams is also described. [less ▲]

This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments. This constitutive model constitutes an effective tool for modelling the thermo-hydro-mechanical (THM) behaviour of geomaterials involved in the confinement of nuclear waste disposal. [less ▲]

In architectural design process, the human error has a particular status. The later it is detected, the more expensive it is. Moreover, some errors can not be detected given the current state of the design process and object definition. In this paper, we propose a model based on cognitive theories about human errors, applied to architectural preliminary design. In this model we classify the consequences of a design decision (direct, indirect, detected and undetected), we describe the steps of decision in architecture in relation to the process of errors detection and we introduce the concept of evolutive context.

Testosterone (T) is a critical endocrine factor involved in the activation of aggressive behaviors. In many vertebrate species, circulating T levels rapidly increase after aggressive encounters during the breeding season. In contrast, we recently showed that circulating T concentrations did not change in white-crowned sparrows in the late breeding season after simulated territorial intrusions. We suggested that changes in local metabolism of T might be more important than changes in systemic T levels. Neural aromatization of T into 17􀀁-estradiol (E2) often mediates the physiological and behavioral actions of T. In vertebrates, aromatase is expressed in several discrete brain regions. We hypothesized that in the late breeding season, brain aromatase is rapidly modulated after aggressive interaction, leading to changes in local concentrations of E2. Wild male white-crowned sparrows were exposed to simulated territorial intrusion with song playback and decoy (STI) or control (CON) for 30 min. STI significantly increased aggressive behaviors. Birds were then caught, rapidly bled and sacrificed. Brains were collected and rapidly frozen on dry ice. We used 0.9 mm diameter punches from 300 μm coronal sections to isolate 13 different brain nuclei. Aromatase activity was analyzed in punches from the left side of the brain, while E2 was analyzed in punches from the right side of the brain. Aromatase activity was quantified by measuring the release of tritiated water during aromatization of [1􀀁-3H]-androstenedione. As expected, aromatase activity was high in the medial preoptic area, ventromedial nucleus of the hypothalamus, hippocampus, bed nucleus of the stria terminalis, nucleus taeniae of the amygdala, and caudomedial nidopallium. Aromatase activity was low in the medial magnocellular nucleus of anterior nidopallium, HVC, Area X, nucleus robustus of the arcopallium, optic lobes, periaqueductal gray and cerebellum. Aromatase activity was not different between the STI and CON groups in any region. There were no significant correlations between aromatase activity and aggressive behaviors or endocrine measures (plasma T, progesterone, corticosterone and corticosteroid binding globulin). These data provide no evidence for rapid modulation of brain aromatase activity following aggressive interactions. It is however possible that aromatase activity is more rapidly modulated (e.g. within 5 min) and these changes were not observed in our 30 min paradigm. We are currently investigating whether local E2 is affected by aggressive interactions. [less ▲]

This paper examines the question of sustainable consumption through the consumer’s contribution to the various dimensions of sustainability. The consumer’s participation reveals legitimacy conflicts in the process of designing new production systems. The different dimensions of sustainability can be linked to different legitimacy models. When the building of new systems entails a concerted process involving dialogue and deliberation among stakeholders from the agricultural and environmental sectors, various legitimacy principles are mobilized and confront each other through the spokespeople who represent the interests involved. This specific case concerns beef produced from the ”Gaume grassland steer,” a system that can be characterized as agroecological and territorial. The consumers who were involved contributed, through deliberative processes, to the coexistence of various legitimacy principles and stakeholder cooperation. This capacity could be linked to their multiple and fuzzy identities because their identities were shown to be flexible, changing with the institutional setting, which was sometimes consumer-oriented and sometimes territory-driven. This allowed them to act as mediators between environmentalists and farmers. To do this they had to be able to accept the limits of each legitimacy principle and contest the possibility of imposing only one principle on all the others. In so doing they helped the heterogeneous actors to reach compromises by referring to a kind of patrimonial common good. [less ▲]

The emergence of several diseases which affects immune system (HIV infections, few cancers) and the expansion of immunosuppressive and chemical anticancer therapies increase mycosis frequency. Treatments currently used to cure mycoses meet problems such as antifungal agent toxicity or pathogenic strain resistance. Thus there is increasing interest for new medical applications of antifungal molecules. In this context, we investigated the behaviour of an antifungal lipopeptide, mycosubtilin, on cytoplasmic membranes. In this aim, biomimetic systems of biological membranes, such as lipid monolayers at the air-water interface and lipid multilayers were used. The interactions of mycosubtilin with these biomimetic systems were examined by different methods (kinetic isotherms, Brewster angle microscopy, FTIR spectroscopy and 1H HR- Magic Angle Spinning NMR). We demonstrated an original behaviour of mycosubtilin in the presence of sterol monolayer, suggesting a mycosubtilin-sterol affinity. We showed as well that mycosubtilin can interact with C=O ester residues and alkyl chains of phospholipids. Moreover, mycosubtilin has a preference for condensed phospholipid domains. [less ▲]
