Nonlinear vibration absorbers are known as being frequency-robust but not amplitude-robust devices. This lack of amplitude robustness is due to the frequency-energy dependence of their related nonlinear oscillations. This feature makes the design of nonlinear vibration absorbers a particulary challenging problem. In this paper an innovative design procedure of a nonlinear vibration absorber is proposed so that a nonlinear mode of a nonlinear primary structure can be controlled in a frequency and amplitude robustness fashion.

Today, coral bleaching represents a major concern for marine biologists, especially considering the upsurge of this phenomenon possibly linked to climate change. Bleached corals, deprived of most of their energy incomes, may show a partial or total mortality, which ultimately lead to shifts in reef communities. Studies focusing on cellular bleaching mechanisms have shown different ways by which algae may be expelled from gastrodermal host cells. Among those mechanisms, major emphasis has been put on host cell death, most probably due to both apoptosis and necrosis. Recovering gastrodermis is then expected to undergo regeneration process in order to be reinfected by new algae. We describe here this regeneration process in the bleached sea anemone model A. pallida. [less ▲]

The high productivity of coral reef ecosystems is largely attributed to the mutualistic symbiosis between reef-building corals and their intracellular dinoflagellate in the genus Symbiodinium commonly referred to as zooxanthellae. These photosynthetic algae translocate a majority of their photosynthetically fixed carbon to the host and contribute to their metabolic needs and the calcification process. <i>Symbiodinium</i> must maintain a balance between the energy derived from the light reactions in the chloroplast and the amount of energy used during dark reactions and other metabolic processes. Nevertheless, in the natural environment the holobiont have to cope with daily and seasonal changes in light intensity, upsetting that balance and creating a stress that induces a physiological response (photoacclimation) to optimize growth rates. After a ten day exposition to high and very low light intensity, morphological and photophysiological analysis conducted on the symbiotic sea anemone, Anemonia manjano, reveal significant modifications of the host tissues ultrastructure and the Symbiodinium metabolic processes (photosynthesis, respiration). Those results highlight particularly important gastrodermal and ectodermal plasticity in which symbiotic cnidarians acclimate to the Symbiodinium physiological status (mainly photosynthesis) by varying the density of particular cellular types (e.g.: cnidocytes, gastrodermal cells) contained in their tissues.

An ensemble smoother scheme is presented to assimilate high-frequency (HF) radar surface currents to improve tidal boundary conditions and wind forcings of a circulation model of the German Bight. To create an ensemble of dynamically realistic tidal boundary conditions, a cost function is formulated which is directly related to the probability of each perturbation. This cost function ensures that the perturbations are spatially smooth and that the structure of the perturbations satisfies approximately the harmonic linearized shallow water equations. Based on those perturbations an ensemble simulation is carried out using the full three-dimensional General Estuarine Ocean Model (GETM). Optimized boundary values are obtained using all observations within the assimilation period using the covariances of the ensemble simulation. The approach acts like a smoother scheme since past and future observations are taken into account. The final analysis is obtained by rerunning the model using the optimal perturbation of the boundary conditions. The analyzed model solution satisfies thus the model equations exactly and does not suffer from spurious adjustments often observed with sequential assimilation schemes. Model results are also compared to independent tide gage data. The assimilation also reduces the model error compared to those sea level observations. The same scheme is also used to correct surface winds. Surface winds are crucial for accurately modeling the marine circulation in coastal waters. The method is validated directly by comparing the analyzed wind speed to in situ measurements and indirectly by assessing the impact of the corrected winds on sea surface temperature (SST) relative to satellite SST.

Le bassin versant de l’Abiergué, situé dans les arrondissements de Yaoundé II et VII, connaît une importante activité maraîchère localisée dans les bas fonds de Nkolbikok à Nkolbisson. L’étude présentée, basée sur l’approche ECOSANTE, a permis de faire une radiographie de cette activité. Les statuts socio-économiques des acteurs impliqués dans cette filière ont été décrits. Les contraintes et les atouts liés au développement du maraîchage ont été relevés. Les eaux usées utilisées par les maraîchers pour l’arrosage des plantes proviennent de diverses origines (ménages, centres de santé, etc.) et sont fortement contaminées avec des teneurs élevées en nitrates, azote ammoniacal, DCO, Coliformes fécaux et Streptocoques fécaux. Des taux variables de kystes de protozoaires (E. histolotica, et Giardia sp) et des œufs d’helminthes ont été décelés dans ces eaux. L’utilisation de ces eaux usées a pour corollaire l’émergence des maladies hydriques telles que l’amibiase intestinale et la bilharziose qui affectent aussi bien les acteurs engagés dans cette filière que la population en général indépendamment du sexe, de l’âge ou du statut social. De nombreux comportements et pratiques à risque qui concourent à la vulnérabilité des groupes d’acteurs aux maladies hydriques ont été identifiés. Au final, des recommandations ont été proposées en vue d’améliorer les conditions sanitaires et environnementales liées à cette pratique de maraîchage urbain. [less ▲]

The gastropod Coralliophilla meyendorffi is a common predator of the zooxanthellate anemone Anemonia viridis. Zooxanthella from the anemones are an important constitutent of the mollusc faeces. Cell integrity, occurence of flagellated forms, live/dead proportions and mitotic index of Symbiodinium collected from the faeces and cultivated in vitro were examined and compared to that of algae in hospite. The results show that most algae withstand digestive processes of the predator, staying alive and dividing actively in the faeces. Motile (lagellated) algae arise from dividing cells and escape the fecal pellets. Impact on coral bleaching recovery is discussed. [less ▲]

Concrete filled steel hollow section (CFSHS) columns can carry important loads and therefore are used extensively in the construction of high-rise buildings. Steel hollow sections are filled usually with ordinary concrete, but filling problems may arise with small cross sections and dense reinforcement or hollow sections (tubes) surrounding another profile (tube or H section) when the distance between the two profiles is small. For such a configuration, self-compacting concrete can be recommended. Ten columns filled with self-compacting concrete embedding another steel profile have been tested in the Fire Engineering Laboratory of the University of Liege - Belgium. The non linear finite element software SAFIR developed at the University of Liege has been used to simulate the thermal and structural behavior under fire conditions. A good agreement between numerical and experimental results has been obtained. This shows that SAFIR code can predict well the behavior of CFSHS columns and that the properties of self-compacting concrete at high temperatures can be considered to be the same as those of ordinary concrete. Another purpose of this study was to give practical tools to consulting engineers. [less ▲]

The present work offers an approach to the relative orbital motion by using hypercomplex algebra. An extension to this notion is used for vectors, by introducing the hypercomplex vector in the same way as hypercomplex numbers are defined. The solution to the relative orbital motion is offered in all possible situations (it stands for any Keplerian reference or targeted trajectories). A unified view on the relative orbital motion is suggested, by generalizing the previous approaches. The solution is offered to the nonlinear model of the relative motion and it is expressed in a coordinate-free hypercomplex vectorial closed form. The key element of this approach is the hypercomplex eccentric anomaly, introduced via a Sundman-like vectorial regularization. [less ▲]

The present article seeks to determine whether sector inquiries are a “substitute” or a "complement” to conventional competition enforcement techniques. The analysis shows that not unlike a “Swiss knife”, sector inquiries constitute a convenient, multifunctional tool, which serves a variety of purposes. Sector inquiries indeed entitle the Commission to (i) lower the minimal procedural requirements which must be met to launch investigations; (ii) extend the substantive scope of its inquiries beyond mere infringements to Article 101 and 102 TFEU; and (iii) incentivize firms to spontaneously comply with the antitrust rules. In light, however, of a number of shortcomings arising from the Commission’s sector inquiries’ practice, this article formulates several “best practices” (which are also relevant for other competition authorities with similar powers).

Attested from the Thinite Period (ca 3100-2650 BC) onwards and mentioned in the Text Pyramids, the goddess of Imet (Imtyt) settled in a specific part of the Egyptian land only at a late stage of her history. After being present in the area of the ancient Avaris from the Middle Kingdom (1990-1760 BC) on, where she acquired the name of Uadjet, Lady of Imet, it is at the very beginning of the 18th Dynasty (1539-1292 BC) that her cult settled in what is nowadays the modern site of Tell el-Faraun, in the Eastern Delta. Documents from and about Imet allow to trace the theological evolution of the place, which shows the appearance and disappearance of several deities at the goddess’ side. This paper examines these evolutions and especially focuses on the development of a local Triad during the 1st Millennium BC. [less ▲]

The clinical hallmarks of Parkinson's disease (PD) are movement poverty and slowness (i.e. bradykinesia), muscle rigidity and limb tremor. The physicians usually quantify these motor disturbances by assigning a severity score according to validated but time-consuming clinical scales such as the Unified Parkinson's Disease Rating Scale (UPDRS) - part III. These clinical ratings are however prone to subjectivity and inter-rater variability. The PD medical community is therefore looking for a faster and more objective rating method. As a first step towards this goal, a tri-axial accelerometer-based system is proposed as patients are engaged in a repetitive finger tapping task, which is classically used to assess bradykinesia in the UPDRS-III. After developing the hardware, an algorithm has been developed, that automatically epoched the signal on a trial-by-trial basis and quantified, among others, movement speed, amplitude, hesitations or halts as validated by visual inspection of video recordings during the task. The results obtained in a PD patient and an healthy volunteer are presented. Preliminary results show that PD patients and healthy volunteers have different features profiles, so that a classifier could be set up to predict objective UPDRS-III scores. [less ▲]

This study evaluated the contribution of implementation intentions over the constructs of the theory of planned behaviour in testing a confirmatory model explaining the relationships between antecedents of academic achievement for university students. It was found that the effects of intention to perform and its classic antecedents on exams performance were mediated by implementation intentions with a considerable increase of amount of explained variance above the contribution of the constructs of planned behaviour theory. This paper is organized as follows. We first introduce the construct of intention, particularly in the context of the well documented model of the theory of planned behaviour (TPB). The limitation of this model will be explained and a basic distinction it does not consider will be pointed to: forming an intention vs. implementing it. Then we present the Heckhausen and Gollwitzer's Action Phases Model (APM) and the construct of implementation intention. The results of experimental and correlational researches on the predictive power of this construct, especially in the educational domain, will be discussed. Thirdly, we propose an integrative model which fills the gap between TPB and performance by introducing implementation intentions from unwanted inner states. Fourthly, we give the results of an experimental research aiming in testing this model conducted in an educational settings and using a confirmatory design (Structural Equation Modelling). In the end, we insist on the implication of these results for students. [less ▲]

Substructured and layered thin sheets can be found in a variety of structural, e.g. structured panels, as well as high-tech applications. A typical example is flexible electronics, e.g. flexible displays, where layers of different materials and interconnects are stacked to provide the necessary functionality. The resulting complex three dimensional geometry of the structured thin sheets in this type of applications prohibits the use of classical layer-wise composite shell theory. For these problems, a computational homogenization technique for thin structured sheets is proposed in this work, based on the computational homogenization concepts previously developed for the first- and second-order continua.

Induced by climate change, intensity and frequency of droughts should be more important for the next century. How does water availability affect the physiology of woody plants at the species and stand scale? Carbon and water vapour fluxes measurements of a mixed forest (deciduous and coniferous) were performed for over ten years by the eddy covariance method in Belgian Ardennes (Aubinet et al, 2001) as a part of the CarboEurope project. Whereas carbon fluxes have been analyzed in detailed and good estimations of the Net Ecosystem Exchange (NEE) and Gross Primary Production (GPP) were obtained, a thorough analysis of water vapour fluxes remains to be done. Improving analysis of water vapour fluxes and monitoring species transpiration will contribute to the estimation of the water use efficiency, WUE, at both the species and stand scale. The WUE well characterizes the vegetation productivity and ecosystem response to environmental factors. It also allows evaluating the sensitivity of temperate woody species to drought. The species concerned are beech (Fagus sylvatica L.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and silver fir (Abies alba Mill.). Since summer 2009 we monitor and analyze each species water use by measuring sap flow with the thermal dissipation method (Granier, 1987). Results at the species level will then be upscaled and compared to stand water vapour fluxes measurements obtained by the eddy covariance methodology. Transpiration of each species will be analyzed in relation with their own phenological and ecophysiological attributes, ecosystem soil and atmospheric conditions, to clarify among others their behaviour in case of water deficit. Data are actually analysed, the presented results will concern the 2009, and a part of 2010 growing season. [less ▲]

This paper deals with the simulation of two extrusion tests by thixoforming: a non stationary extrusion test and a double-cup extrusion test. The simulations are based on a thermo-mechanical one-phase constitutive law that has been presented in details in several previous papers. A campaign of experimental extrusion testing has been conducted on a steel alloy and the comparison between the numerical and experimental results will validate the model under study. A new feature that has been added to the model is also discussed: the introduction of the phase change thermal effects such as the fusion latent heat and the contraction of the material. [less ▲]

Le but de ce travail est de comparer l’extraction faite par chauffage classique (CC) avec celle réalisée sous micro-ondes (MO). Deux modes d’extraction ont été réalisés : - L’hydro-distillation par chauffage classique (extraction par entraînement à la vapeur d’un solvant) et, - L’hydro-distillation activée par micro-ondes. Les MO permettent un gain de temps considérable. Par exemple, dans le cas du lavandula dentata : on note une cinétique 3 fois plus rapide, de plus le rendement est nettement supérieur (1% contre 0,6% par chauffage classique). Dans le cas de la plante fraiche, l’extraction est faite en absence de solvant sous MO. Ceci présente un grand intérêt sur le plan économique et environnemental. De plus, la qualité de l’huile extraite présente généralement une meilleure pureté. L’extraction par MO constitue une technique en accord avec la chimie verte. Grâce à ce procédé, on pourra alors réduire d'environ 60 % les besoins en énergie, ce qui diminuera d'autant les émissions de gaz à effet de serre. [less ▲]

This paper presents the results of combined economic and computational study of different integrated passive and active design strategies for the Red Sea Coastline of Egypt. A chalet, located in Ain-Sukhna is selected as a case study for the zero energy retrofit. The aim of the study is to investigate the potential of achieving thermal comfort and delivering electrical demands for existing buildings on site. The Red Sea Coastline of Egypt has a semi arid climate with an annual total irradiation above 2409 bankable kWh/m2 per year with approximately 3300 hours of full sunshine. Moreover, the annual monthly averages of wind speed in this region range from 5.0 to 7.1 m/s. Therefore, different passive and active design strategies are discussed and compared to reach an annual net zero energy demand for the existing building stock. In order to achieve zero energy retrofit certain strategies are examined. For example, internal loads reduction, envelope retrofitting in addition to the installation of solar water heater, photovoltaic and small-scale wind turbine. Based on a month-by–month demand analysis, internal loads and envelope performance are analyzed in order to explore the existing economical potential. Simulation software TRNSYS is used to predict the annual net zero energy performance for a chalet at Ain-Sukhna. The final result of this study compares the potential and constraints of each strategy and rank them based on economical feasibility. For the considered location and weather conditions the Chalet can provide thermal comfort for occupants and meets the zero energy objectives. The research also proofs that some strategies applied for retrofitting are economical rewarding with a payback period ranging from 2 to 7 years. [less ▲]

Context: Deficient HRH management – especially insufficient training and motivation, and adverse distribution of qualified staff countrywide, at the expense of poor and remote areas – has been identified for over a decade as one major constraint for the implementation of Mali's national health policy. Main objective: The HRH policy aims to define a coherent framework for the ministry of health (MoH) and its partners in order to ensure the harmonious development, distribution, management and motivation of health staff so as to ultimately improve health results. The policy is translated into an operational plan dealing specifically with training, recruitment, motivation, and career management. Methodology: The HRH policy and plan were developed by a core team under the leadership of the Planning Department of the MoH, with the involvement from other departments of the MoH, the ministries in charge of finance (MoF) and civil service (MoCS), and donors. After analyzing existing studies and data, the diagnosis over the major problems to be tackled was done. This allowed identifying the main orientations of the policy, which were then translated into strategies and interventions, and then costed. Once the policy and plan have been drafted by the core team, they have been circulated to all departments and partners and discussed in several meetings with different stakeholders at central level. After integrating comments from these meetings, the MoH organized a validation workshop with very broad participation (including the operational level, private sector, and civil society) so as to ensure ownership. Final amendments were negotiated with the MoF and MoCS in order to be adopted as a national policy by the Counsel of Ministers by the end of 2009. Results: The HRH policy and plan now benefit from wide political support by major stakeholders. Yet, implementation still has been delayed because of the management modalities at operational level still need to be definitively agreed upon. Conclusion: The inclusive development process has been necessary to move on with the complex and highly sensitive issue of HRH management, and to get the support from MoF, MoSC and donors who are supposed to contribute to its financing.

A sub-problem finite element method is developed for refining the inductor models in magnetic circuits. It applies electrokinetic, magnetostatic and magnetodynamic models on progressively more complicated geometries and different components of the solution, supported by different meshes.

The measurements of the linear polarisation of visible light from quasars give strong evidence for large-scale coherent orientations of their polarisation vectors in some regions of the sky. We show that these observations can be explained by the mixing of the photons with very light pseudoscalar (axion-like) particles in extragalactic magnetic fields during their propagation. We present a new treatment in terms of wave packets and discuss the circular polarisation. [less ▲]

From the analysis of measurements of the linear polarisation of visible light coming from quasars, the existence of large-scale coherent orientations of quasar polarisation vectors in some regions of the sky has been reported. Here, we show that this can be explained by the mixing of the incoming photons with nearly massless pseudoscalar (axion-like) particles in extragalactic magnetic fields. We present a new treatment in terms of wave packets and discuss its implications for the circular polarisation. [less ▲]

In context of the development of the genetic evaluation system of Piétrain boars for crossbred performances, a genetic evaluation model was developed for the estimation of genetic merit of boars for backfat thickness (BF) and meat percentage (%meat). The model developed was a random regression model using linear splines on age which knots at 175, 200 and 250 days. Variance components were estimated by restricted maximum likelihood and Gibbs sampling. Estimated heritability from 150 to 300 days increased from 0.56 to 0.75 for BF and from 0.55 to 0.69 for %meat. Genetic correlation between BF and %meat varied between -0.90 and -0.93 from 150 to 300 days. According to the study of residuals, the developed model was considered to fit well the data especially between 175 and 250 days of age. [less ▲]

In teleost fishes, the lateral system is assumed to contribute, among other roles, to maintaining schooling behaviour. Sight is also assumed to play a role in schooling, as fish with a cut lateral line do not stop schooling unless they are also blinded. This conclusion, however, was based on experiments where only the trunk lateral line was inactivated, leaving the head lateral system intact. Here the aim was to test how inactivation of the whole lateral system affects the fish shoaling behaviour. Groups of firehead tetras, Hemigrammus bleheri, were video-recorded before and after inactivation of their whole lateral system with aminoglycoside antibiotics (and also in sham-treated specimens). Shoaling behaviour was characterized by: nearest distance to the first, second, and third neighbour, shoal radius, shoal order parameter, and the number of collisions between individuals. SEM observations showed damage to most superficial neuromasts as a result of antibiotic treatment. Importantly, the antibiotic-treated fish proved unable to maintain a shoal. After the end of the treatment, however, they recovered both a normal tissue morphology and normal shoaling behaviour within about a month. The lateral system is thus more crucial to shoaling behaviour than previously believed. [less ▲]

Au delà de ses implications techniques, l'informatisation de l'analyse de texte soulève des questions de méthode. Après un recensement des motivations à recourir à des logiciels pour assister l'analyse de données textuelles, nous proposons une typologie distinguant cinq fonctionnalités proposées par ces outils : la lexicométrie, les concordances, les automates, les outils réflexifs et les dictionnaires. Chacune de ces fonctionnalités éclaire les textes d'une manière originale (et partielle). Rapportée à ses usages attestés, chacune de ces potentialités articule des présupposés épistémologiques spécifiques. En définitive, le choix d'un logiciel caractérise autant une démarche de recherche que l'inscription dans un paradigme. [less ▲]

Au début des années 70, le Congo Kinshasa est touché par un mouvement de réveil (pentecôtiste) sans précédent. Trois décennies plus tard, c’est un paysage religieux pluriel et très contrasté, pour ne pas dire concurrentiel, qui se donne à voir. Néanmoins, la frontière entre « monde chrétien » et « monde païen » que matérialise un système d’interdits fort, constitue un invariant fédérateur et significatif de l’impératif marquant ce christianisme de conversion. Et pourtant le rappel à l’ordre récurrent, parfois la plainte, des pasteurs à l’endroit des fidèles qui passent « d’une Eglise à l’autre » rend intelligible la perméabilité de cette frontière. Ce que nous mettrons en perspectives en appréhendant ces mobilités sous l’angle d’espaces interstitiels constitutifs de ces mondes religieux. [less ▲]
