[more ▼]Shallow reservoirs are used for multiple purposes, such as storm water retention and trapping of sediments. Reliable predictions of the flow fields are necessary to inform the design and operation of these structures. Using numerical simulations, we performed a systematic analysis of the influence of the location of the inlet and outlet on the flow fields developing in rectangular shallow reservoirs of various sizes. Depending on the relative location of the inlet and outlet with respect to the reservoir centreline, contrasting flow patterns are obtained, involving either no flow reattachment, or a jet reattached on either of the reservoir sidewalls. The results reveal also the occurrence of bi-stable flow configurations, i.e. different steady state flow fields are reached depending on the flow history. This is of high relevance for the design of shallow reservoirs as such configurations should certainly be avoided to achieve a robust hydraulic sizing of the reservoir.

[more ▼]In poultry, feed based on maggots, like larvae of Black Soldier fly (Hermetia illucens) is an attractive option to substitute current ingredients which are expensive and often in direct or indirect competition with human food. Little information is currently available on the utility of these larvae in poultry feed, so goals of this study were to determine whether larvae could be reared on horse manure under traditional farming conditions and to evaluate the growth performances of a local poultry fed these larvae and the fatty acids profiles of their meat. After freezing and thawing, larvae were introduced in the feed of Ardennaise chickens between 30 and 80 days of age. Birds in the control group received a commercial standard feed while those in the treatment group received the same commercial feed in which 8% was substituted with whole fresh larvae corresponding to 2% on a dry matter basis. Mean ± standard errors of larval length and weight were 20.67 ± 2.21 mm and 0.14 ± 0.02 g, respectively. Mean larval percentages of dry matter and of substances extractable in diethyl ether were 24.6% and 23.1%, respectively. Larval fatty acids profiles were predominantly composed of lauric (28.1%) and palmitic (22.0%) acids. Least squares means of weekly weights of chicken, adjusted for the effects of sex, replication and initial weights, were significantly higher (P < 0.05) by 77.03 ± 53.37 g in larvae-fed than in control chickens. All the other measurements were not statistically different between larvae-fed and control chicken, including fatty acid profiles, protein content and ω6/ω3 ratio. In conclusion, the use of black soldier fly larvae in the diet of local chicken breed may be an alternative to the use of soy.

[more ▼]Despite the common conception of the dorsal premotor cortex (PMd) as a single brain region, its diverse connectivity profiles and behavioral heterogeneity argue for a differentiated organization of the PMd. A previous study revealed that the right PMd is characterized by a rostro-caudal and a ventro-dorsal distinction dividing it into five subregions: rostral, central, caudal, ventral and dorsal. The present study assessed whether a similar organization is present in the left hemisphere, by capitalizing on a multimodal data-driven approach combining connectivity-based parcellation (CBP) based on meta-analytic modeling, resting- state functional connectivity, and probabilistic diffusion tractography. The resulting PMd modules were then characterized based on multimodal functional connectivity and a quantitative analysis of associated behavioral functions. Analyzing the clusters consistent across all modalities revealed an organization of the left PMd that mirrored its right counterpart to a large degree. Again, caudal, central and rostral modules reflected a cognitive- motor gradient and a premotor eye-field was found in the ventral part of the left PMd. In addition, a distinct module linked to abstract cognitive functions was observed in the rostro- ventral left PMd across all CBP modalities, implying greater differentiation of higher cognitive functions for the left than the right PMd.

[more ▼]In this case study, we study the generation of warning waves with prescribed characteristics in a mountain stream. We determine which dam release will generate the desired warning wave. We solve this inverse problem following a two-model approach. An analytical kinematic model is used for a preliminary design of the dam release and a detailed two-dimensional (2D) fully dynamic model is used to converge to the final solution. Although the presented case study is far from an idealized academic case, the analytical model performs well and, beyond its role for preliminary design, turns out to be of prime interest for both understanding and discussing the results of the detailed 2D model. The complex interactions between the release hydrograph, the geometry of the river and the friction formula are brought to light by the analytical model, which highlights the complementarity of both models and the usefulness of such a two-model approach.

Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

[more ▼]Stiction is a failure mode of microelectromechanical systems (MEMS) involving permanent adhesion of moving surfaces. Models of stiction typically describe the adhesion as a multiple asperity adhesive contact between random rough surfaces, and they thus require a sufficiently accurate statistical representation of the surface, which may be non-Gaussian. If the stiction is caused primarily by multiple asperity adhesive contact in only a small portion of the apparent area of the contacting surfaces, the number of adhesive contacts between asperities may not be sufficiently statistically significant for a homogenized model to be representative. In [Hoang et al., A computational stochastic multiscale methodology for MEMS structures involving adhesive contact, Tribology International, 110:401-425, 2017], the authors have proposed a probabilistic multiscale model of multiple asperity adhesive contact that can capture the uncertainty in stiction behavior. Whereas the previous paper considered Gaussian random rough surfaces, the aim of the present paper is to extend this probabilistic multiscale model to non-Gaussian random rough surfaces whose probabilistic representation accounts for the high order statistical moments of the surface height. The probabilistic multiscale model thus obtained is validated by means of a comparison with experimental data of stiction tests of cantilever beams reported in the literature.

[more ▼]This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No pier effect or air venting is considered in the study. The velocity field is measured by Bubbles Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparison of measured velocities between both spillways indicates low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity calculated from the relative pressure considering a potential flow finally emphasizes that bottom pressure amplitudes seem overestimated for the larger spillway, while an averaging effect might operate for the pressure measurements on the smaller spillway.

[more ▼]The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10$^{-3}$ in the near-infrared with PIONIER (H band) and GRAVITY (K band). Nulling interferometers in the northern hemisphere and non-redundant aperture masking experiments have, however, demonstrated that contrasts of at least a few 10$^{-4}$ are within reach using specific beam combination and data acquisition techniques. In this paper, we explore the possibility to reach similar or higher contrasts on the VLTI. After reviewing the state-of-the-art in high-contrast infrared interferometry, we discuss key features that made the success of other high-contrast interferometric instruments (e.g., integrated optics, nulling, closure phase, and statistical data reduction) and address possible avenues to improve the contrast of the VLTI by at least one order of magnitude. In particular, we discuss the possibility to use integrated optics, proven in the near-infrared, in the thermal near-infrared (L and M bands, 3-5 $\mu$m), a sweet spot to image and characterize young extra-solar planetary systems. Finally, we address the science cases of a high-contrast VLTI imaging instrument and focus particularly on exoplanet science (young exoplanets, planet formation, and exozodiacal disks), stellar physics (fundamental parameters and multiplicity), and extragalactic astrophysics (active galactic nuclei and fundamental constants). Synergies and scientific preparation for other potential future instruments such as the Planet Formation Imager are also briefly discussed.

[more ▼]Singlet oxygen-based photocatalytic oxygenation reactions have emerged as an efficient technology to synthesize value-added organic molecules. Among organic substrates, bio-sourced molecules such as aminoacids or terpenes have a promising forecast as synthetic building blocks. A pseudo first-order kinetic study for the photocatalytic oxygenation of natural amino acid (L)-methionine was carried out in a macroscopic batch reactor. Various parameters were studied, including the effect of the photosensitizer (Rose Bengal, RB) concentration, the intensity of the light and the O2 flow in terms of apparent kinetic constants and space-time yields. The identification of important limiting parameters as pressure, gas flow or light efficiency during the photocatalytic oxygenation of methionine allowed its transition from macroscopic batch reactor to continuous-flow microreactor.

[more ▼]Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

In its decision, the Federal Constitutional Court confirms the conformity of the ECB's monetary program (Outright Monetary Transactions) with EU law and German constitutional law, but maintains nevertheless some "serious objections" against the CJEU's position, thus nourishing the possibility – also perceptible in other EU Member States (France and Belgium in particular) – of an open confrontation between national constitutional courts and the CJEU.

[more ▼]Negotiations on the liberalization of environmental goods (EGs) and services within the WTO Doha Round (mandated in November 2001) are facing specific challenges. Conflicting interests and differing perceptions of the benefits of increased trade in EGs were reflected in different approaches proposed for determining EGs. Using import data of 34 Organisation for Economic Co-operation and Development (OECD) member countries and from a sample of 167 countries, from 1995 to 2012, we discuss the trade effect of reducing barriers on EGs. We analyze the lists of EGs proposed by the Asia-Pacific Economic Cooperation and OECD using a Translog gravity model. We found that removing tariff barriers for EGs will have a modest impact because for the biggest importers and exporters, elasticities of trade costs are very low while for most trading relationships they are very high, making it difficult for exporters to maintain their markets. Overall, our results suggest that, because of their substantial effect on international trade, future negotiations on EGs should also address the issues of standards and nontariff barriers.

[more ▼]The synthesis of α-alkylidene cyclic carbonates (αCCs) by carboxylative coupling of CO2 with propargylic alcohols is receiving increasing interest but requires the use of catalysts that are most often added in large quantity and/or are lacking of selectivity. Herein, we describe that the fine tuning of the structure of organocatalysts of the ammonium-type enables to identify the important structural parameters that dictate their catalytic performance. Tetrabutylammonium oxalate revealed to be one of the most attractive organocatalysts with a remarkable fast, complete and selective production of αCCs at low catalyst loading (2.5 mol%) under solvent free-conditions. This study clearly opens new avenues for the facile and selective synthesis of libraries of αCCs from CO2 and propargylic alcohol by using simple organocatalysts.

[more ▼]A strand of empirical research on deindustrialization seeks to quantify the relative importance of the economic forces behind deindustrialization, and especially of the internal and external factors, i.e. those linked to globalization and trade. The results of this literature are highly fragile, arguably because the commonly used indicators of trade are not well defined to capture the contribution of globalization to deindustrialization. While this empirical study does not necessarily contradict the widespread belief that the internal factors are quantitatively more important in accounting for deindustrialization in the OECD taken as a whole, our empirical results – based on panel data for 15 OECD advanced countries from 1970 to 2006 – nevertheless show that global exchanges have the potential to affect significantly and substantially a country’s sectoral patterns of employment. They also suggest that the contribution of globalization, and especially of growing North-South integration, to deindustrialization in advanced countries may be revised upwards when resorting to better-suited indicators of trade.

[more ▼]Purpose The fracture stage of non-traumatic osteonecrosis (ON stage 3) of the femoral head (ONFH) has an unfavourable prognosis frequently requiring total hip replacement (THR). The percentage could be lowered after core decompression. In earlier non-fracture ON stages, implantation of autologous bone marrow aspirate concentrate (BMAC) improved the effect of core decompression. The purpose was to evaluate the effect of BMAC in addition to core decompression in stage 3 ONFH. Methods A double blind RCT was conducted comparing two groups: core decompression plus saline injection or core decompression plus BMAC implantation. Both patients and assessors were blinded to the treatment assignments. Evaluations were done at baseline, three, six, 12, and 24 months, including pain (VAS), WOMAC, side-effects, radiological evolution including ARCO subclassifications, together with possible THR requirement. The primary endpoint was the need for THR. The second endpoints included the clinical symptoms such as pain and functional ability and the progression of the ON lesions as well as the appearance of osteoarthritis features (ARCO stage 4). Both groups included 23 hips (19 patients). Results No differences were found between the groups for THR requirements, clinical tests, and radiological evolution. In both groups, 15/23 hips needed THR. The radiological evolution of the ONFH lesions in term of location, extension, surface collapse, and dome depression was moderate in both groups and was not correlated with the need of THR. Conclusions Implantation of BMAC after core decompression did not produce any improvement of the evolution of ONFH stage 3.

[more ▼]The terrestrial Antarctic Realm has recently been divided into 16 Antarctic Conservation Biogeographic Regions (ACBRs) based on environmental properties and the distribution of biota. Despite their prominent role in the primary production and nutrient cycling in Antarctic lakes, cyanobacteria were only poorly represented in the biological dataset used to delineate these ACBRs. Here we provide a first high-throughput sequencing (HTS) insight into the spatial distribution of benthic cyanobacterial communities in Antarctic lakes located in four distinct, geographically distant ACBRs and covering a range of limnological conditions. Cyanobacterial community structure differed between saline and freshwater lakes. No clear bioregionalisation was observed, as clusters of community similarity encompassed lakes from distinct ACBRs. Most phylotypes (77.0%) were related to cyanobacterial lineages (defined at ≥ 99.0% 16S rRNA gene sequence similarity) restricted to the cold biosphere, including lineages potentially endemic to Antarctica (55.4%). The latter were generally rare and restricted to a small number of lakes, while more ubiquitous phylotypes were generally abundant and present in different ACBRs. These results point to a widespread distribution of some cosmopolitan cyanobacterial phylotypes across the different Antarctic ice-free regions, but also suggest the existence of dispersal barriers both within and between Antarctica and the other continents.

Most probably it is due to its apparent lack of stature. Indeed, subjected to Philip II’s ambassador in Rome, the agency tasks were limited. It was only able to look after the ecclesiastic affaires of Southern Netherlands and Franche-Comté during the negotiations at the roman curia. However a strategies and network analysis allows to requalify this reading. Through socio-professional strategies of agent Laurent du Blioul, the institution was able to use, maintain and increase royal influence on the city. Our analysis clearly shows that the agency’s standing exceeds Brussel’s interest and Laurent du Blioul was a real stakeholder of the polycentric construction of the Monarchía.

[more ▼]This paper aims at, firstly, highlighting the morpho-biometric characteristics of the Tazegzawth sheep breed, and, secondly, describing the sheep farmers profile and their farming practices. The study was carried out in Kabylie (Algeria) which is the breed cradle of Tazegzawth sheeps. The essay concerned 16 breed farmers located in the Wilayas of Bejaia and Tizi-Ouzou. Each of the 85 sheeps (24 rams and 61 ewes) was characterized and profiled. The study indicated that the sheep farming is a diversification activity and not a specialized activity. Other breeds and species are kept by the farmers. Due to the sharing of grazing areas between farmers, anarchic matings occurred contributing to the Tazegzawth breed’s decline. Farmers involved in this study were male having on average 12.13±3.84 livestock heads per household. All the farmers used local resources as supplement feeding: organic waste, crop leftovers, hay and olive foliage, ash, elm, oak and fig foliage. Average live weight of males (68.48±1.12 kg) were highly significantly higher (p-value <0.01) than the average live weight of females (53.84±1.16 kg). Livestock systems involving Tazegzawth breed showed high diversity. The multiple correspondences analysis indicated 4 groups depending on the time length over which animal breeding took place, the bred animal species, the number of Tazegzawth bred animals, and the aims and objectives of the animal farming.

My main goal is to show that the ambiguities and tensions generated by we narration in these two Asian American novels prove particularly apt when it comes to calling into questions essentialist views concerning the anatomy of community-building. But these two we texts are particularly interesting at a theoretical level, in that they help us challenge the orthodoxies of traditional narrative theory– among which Gérard Genette’s all-too-rigid distinction between the homo- and heterodiegetic levels in a text, or the generalized assumption, which has been notably challenged by Mieke Bal, that every act of story-telling is necessarily indebted to ‘a’ narrator, and a narrator of anthropomorphic standards at that.

[more ▼]The purpose of this paper is to provide a comprehensive state of the art of fatigue and cyclic loading of natural rock materials. Papers published in the literature are classified and listed in order to ease bibliographical review, to gather data (sometimes contradictory) on classical experimental results and to analyse the main interpretation concepts. Their advantages and limitations are discussed, and perspectives for further work are highlighted. The first section summarises and defines the different experimental set-ups (type of loading, type of experiment) already applied to cyclic/fatigue investigation of rock materials. The papers are then listed based on these different definitions. Typical results are highlighted in next section. Fatigue/cyclic loading mainly results in accumulation of plastic deformation and/or damage cycle after cycle. A sample cyclically loaded at constant amplitude finally leads to failure even if the peak load is lower than its monotonic strength. This subcritical crack is due to a diffuse microfracturing and decohesion of the rock structure. The third section reviews and comments the concepts used to interpret the results. The fatigue limit and S–N curves are the most common concepts used to describe fatigue experiments. Results published from all papers are gathered into a single figure to highlight the tendency. Predicting the monotonic peak strength of a sample is found to be critical in order to compute accurate S–N curves. Finally, open questions are listed to provide a state of the art of grey areas in the understanding of fatigue mechanisms and challenges for the future.

[more ▼]A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations and finite fields variations. The multi-physics DG formulation is shown to satisfy the consistency condition, and the uniqueness and optimal convergence rate properties are derived under the assumption of small deformation. First the numerical properties are verified on a simple numerical example, and then the framework is applied to simulate the response of smart composite materials in which the shape memory effect of the matrix is triggered by the Joule effect.

[more ▼]Common clay deposits from five localities in Foumban (West Cameroon) were investigated for their morphological, mineralogical and geochemical properties to determine their potential source rocks and suitability in ceramic product. The analytical results were obtained by X-ray diffraction, X-ray fluorescence spectrometry, Thermogravimetric Analysis, Scanning Electron Microscopy, and Fourier Transform Infrared Spectrometry. Morphologically, an homogeneous clayey layer was found in the upper part of a laterite cover on interfluves, and a clayey heterogeneous hydromorphic material in valleys. They are minerallogically composed of kaolinite (25-84%), illite (0-18%), smectite (0- 31%), and chlorite (0-8 %), associated with quartz (2-44 %), K-feldspars (0-27 %.), plagioclase (0-26%), goethite; (0-9%) with traces of rutile and hematite (≤5 %). The geochemical analysis shows a 115 relative large amount of SiO2 (45-71%), Al2O3 (14-31%), and low Fe2O3 (up to 11 %) suggesting weathering of mainly granitic and rhyolitic parent rocks. Most studied clays could be applied to building ceramic product such as bricks (refractory or not) and tiles. Illite may promote the glassy phase responsible for the densification of the final product. In addition, the relatively high proportion of alkali elements (K2O + Na2O, 6-8%) in some samples from Marom, Koutaba and is responsible for low firing temperature. However the presence of smectite (up to 5 %) limits the application of some Koutaba and Marom clays for ceramic building. The high Fe2O3 contents (> 8 %) in some Bangourain clays implied some pretreatment.

[more ▼]Understanding how the productivity of water can be increased is widely accepted to be a high priority where water resources are currently scarce and/or over-exploited in China. As the primary data source, MODIS remote sensing, statistics, meteorological data, crop growth period data and ground truth-data from Jan. 2011 to Dec. 2012 were used in actual evapotranspiration estimation, yields rasterizing, and water productivity calculation for winter wheat in the Huang-Huai-Hai Plain (3H Plain). The statistical data were synthesized to calculate district-state-level land productivity, which is then further extrapolated to pixel-level values using a MODIS NDVI image, based on a crop dominance map. Spatial variation of crop water productivity was investigated in order to reveal the key factors of crop water productivity. In addition, the relationship between water productivity and actual evapotranspiration and in subsequence yield for winter wheat was discussed in 3H Plain. The main results indicated that the SEBAL is suitable for estimating evapotranspiration in winter wheat based on the comparation between evapotranspiration measured by Yucheng (in Shandong province). The regional average value of water productivity for winter wheat was detected to be 1.21kg·m-3, with the higher value in Beijing, Tianjin, north part of Shandong province and south part of Hebei province. The pronounced relationship of spatial correlation of the yield and water productivity for winter wheat indicated that the increasing yield governed the increment of water productivity for winter wheat in the coastal land-farming-fishing area (zone1), low plain-hydropenia irrigable land and dry land zone (zone2) and basin- irrigable land and dry land (zone5). The increasing water productivity for winter wheat was recognized to be controlled by rather the increment of yield than the reduction of actual evapotranspiration for winter wheat in the piedmont plain-irrigable land (zone2). Whereas, the pronounced relationship of negative correlation of water productivity and actual evapotranspiration for winter wheat described that only the reduction of actual evapotranspiration was responsible for the increment of water productivity for winter wheat in hill-wet hot paddy-paddy field (zone6). The results is expected to provide a basis information for agricultural water management, improvement of crop water productivity and choice of adaptive mechanism under climate change in Huang-Huai-Hai plain.

[more ▼]The majority of methods for calculating the dynamic response of nonlinear aeroelastic systems considers only steady-state periodic behaviour. An exception is the Multiple Time Scales method, which can estimate both the transient and steady-state solutions of such systems; nevertheless, this approach is only accurate close to the Hopf bifurcation. This paper proposes a novel combined approach whereby the transient response is obtained from the Multiple Time Scales method and the asymptotic periodic behaviour is corrected using the Harmonic Balance method. This consistent and efficient framework mutually empowers both techniques and accounts for large parameter variations around the critical condition. The effect of cubic aero-structural nonlinearities on the dynamic response of a generic aeroelastic system is then investigated. Both the Multiple Time Scales and Harmonic Balance methods are adopted and perfect agreement of the explicit results is demonstrated, albeit near the system instability. In contrast, the proposed combined solution is valid for a wider range of perturbations, is analytical and has negligible computational cost while retaining accuracy. The role of key parameters and terms on the core mechanism of the dynamic behaviour is rigorously identified and discussed, from both physical and mathematical points of view. Galloping is finally considered as the simplest but complete application to a fundamental yet practical problem, featuring full conceptual complexity while exploiting the solid synthesis capability of the newly proposed analytical approach. Excellent agreement was found in all cases with results from the numerical integration of the nonlinear equations of motion in the time domain.

However, all variables did not reach satisfying retest reliability. The findings regarding the French version of the MADRE questionnaire are encouraging but a replication with a shorter test/retest interval and a more representative sample is needed.

[more ▼]The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This multi-purpose high-contrast visible and near-infrared (R- to K-band) instrument is not only intended to serve as a VLT-class "planet-imager" instrument in the Northern hemisphere, but also to operate as a technology demonstration testbed ahead of the ELTs-era, with a particular emphasis on small inner-working angle (IWA) coronagraphic capabilities. The given priority to small-IWA imaging led to the early design choice to incorporate focal-plane phase-mask coronagraphs. In this context, a test H-band vector vortex liquid crystal polymer waveplate was provided to SCExAO, to allow a one-to-one comparison of different small-IWA techniques on the same telescope instrument, before considering further steps. Here we present a detailed overview of the vector vortex coronagraph, from its installation and performances on the SCExAO optical bench, to the on-sky results in the extreme AO regime, as of late 2016/early 2017. To this purpose, we also provide a few recent on-sky imaging examples, notably high-contrast ADI detection of the planetary-mass companion \kappa Andromedae b, with a signal-to-noise ratio above 100 reached in less than 10 mn exposure time.

[more ▼]Even if insect pest populations can be reduced by increasing plant diversity through intercropping, natural enemies are not always favored in such systems. Alternatively, semiochemical substances have been tested to enhance biological control, with inconsistent results. Combining both strategies can be an interesting way to maximize pest control. In this work, a 2-year setup involving wheat–pea strip intercropping combined with the release of E-b-farnesene (EBF) or methyl salicylate (MeSA) was tested as a push–pull strategy to simultaneously repel aphids and attract beneficials. Two types of slow-release formulation (i.e., oil and alginate beads) containing EBF or MeSA were deployed with the intercropping. The abundance of aphids was significantly decreased, while hoverfly larvae and mummified aphids increased on both pea plants and wheat tillers by the release of oil-formulated EBF and MeSA. The proportion parasitism of the aphid-parasitism rate [mummies/(aphids + mummies)] was also increased by treating both crops in both years. Releasing EBF through oil rather than alginate beads proved significantly better for attracting natural enemies and reducing aphids. Aphids were negatively correlated with the density of hoverflies (both adults and larvae) and numbers of mummies. All these results showed that combining intercropping with the release of EBF or MeSA formulated in oil can significantly reduce aphid density and attract their natural enemies. Therefore, the combination of both strategies could help farmers reduce the use of insecticides.

[more ▼]The whitemouth croaker, Micropogonias furnieri, is a long-lived fish of high commercial importance in the Western Atlantic Ocean. Here, we used stable isotope ratios of carbon, sulfur and nitrogen and isotopic niche metrics (SIBER) to study feeding habits and track habitat use by whitemouth croakers in Guanabara Bay, an estuary in Rio de Janeiro state, Brazil. Our results highlighted size-related habitat segregation, with small juvenile (< 30 cm) fishes residing mostly inside estuaries, while large adult (> 60 cm) fishes feed mainly in Continental Shelf (CS) waters. Medium adult fishes (30-60 cm) appear to feed in multiple coastal and CS habitats. Moreover, their feeding ecology showed strong temporal differences, linked with seasonal and, to a lesser extent, inter-annual variation in oceanographic features of the ecosystem in which they live. Overall, these differences in ecological features suggest that (1) adult and juvenile whitemouth croakers should be treated as different components of the food web and (2) the conservation of these habitats should be prioritized to better manage and sustain the coastal fisheries in Guanabara Bay.

[more ▼]Pliosaurid marine reptiles played important roles in marine food chains from the Middle Jurassic to the 'middle' Cretaceous, frequently as apex predators. The evolution of pliosaurids during the later parts of the Early Cretaceous has recently been illuminated by discoveries from Russia (Hauterivian) and Colombia (Barremian). However, knowledge of pliosaurids representing the Jurassic-Cretaceous transition (late Tithonian-Valanginian), is still largely incomplete, especially during the earliest Cretaceous. As such, the effect on pliosaurids of hypothesized faunal turnover during the Jurassic-Cretaceous boundary interval is poorly understood. We report pliosaurid teeth from the upper Volgian (Tithonian, Upper Jurassic) of the Kheta river basin (Eastern Siberia, Russia), to the Berriasian and Valanginian (Lower Cretaceous) of the Volga region (European Russia). These assemblages yielded a series of distinct tooth morphotypes, including the first reports of conical-toothed pliosaurids from the latest Jurassic-earliest Cretaceous. This challenges the hypothesis that only one lineage of pliosaurids crossed the Jurassic-Cretaceous boundary. It appears that conical-toothed pliosaurids co-existed with their trihedral-toothed relatives for at least 25 million years during the latest Jurassic and earliest Cretaceous. In fact, our quantitative analyses indicate that pliosaurids reached their maximal dental disparity during this interval, showing little evidence of turnover associated with the Jurassic-Cretaceous transition. Instead, disparity decreased later in the Early Cretaceous, with the disappearance of trihedral-toothed forms in the Barremian.

[more ▼]Hybrid organizational forms combine values and practices from different institutional domains, rendering them difficult to fit neatly into the structures of extant organizational forms. Since the work required to institutionalize a new hybrid organizational form may be beyond the resources and capabilities of individual organizations acting alone, we shift the focus to inter-organizational collective action. Using empirical data from a study of a European network of renewable energy cooperatives, we find that, in order to institutionalize the new hybrid organizational form, the network can contribute to overcome the legitimacy challenges inherent in organizational hybridity. In particular, the network builds field-level receptivity to institutional pluralism, collectively codifies the hybrid organizational form, and consolidates legitimation towards plural field-level audiences. In order to perform these institutionalization roles, the network itself becomes increasingly formalized and mobilizes mediating functions involving different types of resources, legitimacy and target audiences. The research advances knowledge of hybrid organizational forms and their collective institutionalization through inter-organizational networks.

[more ▼]In the current context of the necessary sustainability transition of the built environment, it is widely recognized that buildings are a major contributor to the energy consumption of fossil fuels and the emission of CO2. Most of the debates, policies and research are however dedicated to the sole construction of new very efficient (up to zero-energy) building, neglecting the potential of actions on the existing building stock. In this context, we argue that LCA tools are of a huge interest to objectivize the need to refurbish old buildings, in order to increase their energy efficiency and extend their life span, and to compare this strategy to the demolition / reconstruction of buildings. To achieve this aim, this paper aims at updating an existing tool that enables to carry out the life cycle assessment of buildings, by taking into account demolition and construction phases. Then, the tool is applied to one case study of the low-energy refurbishment of a public office building in Brussels, to compare the impacts of the complete demolition followed by a complete reconstruction (rebuild project) to the retrofitting of the existing building (retrofit project). Our main findings confirm the huge impact of the use phase, highlight the impact (energy and CO2 emissions) of the construction and demolition phases and show that the in-depth renovation of this building leads to lower environmental indicators compared to its full reconstruction. The tool and results provided in this paper support the development of policies in favour of the retrofitting of the existing building stock and highlight the importance of including the whole life cycle of the building in the analysis.

[more ▼]Changing dynamics of power systems caused by the migration from conventional to distributed energy sources increase the risk of blackouts due to voltage instability, especially in case of unforeseen network conditions (e.g., (N-k)-cases). To enable a both secure and efficient power supply, novel monitoring and emergency control systems for the identification of voltage emergency situations as well as the execution of control actions are required that react reliably in due time and adaptively in case of changing network situations. This paper presents a distributed agent-based approach to counteract voltage instability that is based solely on local measurements and limited inter-agent communication. Distributed agents located at substations in the (sub-)transmission network monitor distribution and transmission voltages as well as load tap changer positions and are able to autonomously curtail load in case system stability is endangered. The applicability of the approach is demonstrated in a co-simulation environment interfacing the multi-agent system with a dynamic power system simulation. The presented approach allows for an early detection of voltage instability as well as a coordinated execution of available control actions.

[more ▼]Plant rennets hold an important position amongst various coagulants used in cheese technology. The selection of a suitable plant coagulant is important due to the increasing global demands of cheese alongside reduced supply of calf rennet. Thus, a literature synthesis is presented to investigate recent achievements on their functional properties and enzymatic role in cheese making. Efforts have also been done to compare certain rheological and sensory properties of final products, arising from some plant and animal based rennets. In fact, some coagulants such as actinidin or dubiumin produce cheeses with sensory qualities similar to those produced by animal rennet. Others, like ginger, cucumisin or hieronymain proteases contribute to develop very different textures and flavors, due to excessive proteolytic activity and production of bitter peptides. For milk-clotting enzymes with high non-specific action, several improvement strategies have been developed to produce cheeses with sensory properties close to those of animal rennet. For example, the mixture of coagulants (cardosins/chymosin), the selection of appropriate milk or its ultrafiltration, as well as the increase of salting time of cheese during ripening could be efficient ways to improve texture and reduce bitterness. Concerning cheeses with high yield loss, the whey could be used for a traditional production of whey cheese. To conclude, the selection of appropriate plant rennet with high MCA/PA ratio and the optimization of all coagulation parameters play a central role in manufacturing cheese with superior rheological and sensory properties.

[more ▼]Whether considered as an activity (play) or as a system of rules (game), video games are marked by reflexivity : playing requires the adoption of a distanciated (Henriot, 1969) and metacommunicative attitude (Bateson, 1977), and video games use a plethora of metadiscursive processes (metalepsis, mise en abyme and mirror effect). This connexion between reflexivity and game is particularly clear when considering the avatar : by bringing together an empirical player and a fictional character, this « enveloppe pilotable » (controllable shell ; Amato et Perény, 2013) works as a deixis. As a natural entry point to the fictional world, the avatar continually signifies the loss and the recovery of our control over the game, thus interrogating the player’s posture. The frequency of reflexive figures in video games and the avatar’s pivotal role in these processes question the way video games can build a narration. Because they can interrupt the construction of the fictional world in order to generate a discourse on the game itself, these figures could indeed be seen as disrupting the figurative power of the game. In order to shed some light on the mechanisms behind the transgression of the boundaries of the fictional world and their function in articulating the game and the fiction, this paper will analyze these formal mechanisms through three distinct games : Portal (Valve Corporation, 2007), The Stanley Parable (Galactic Cafe, 2013) and INSIDE (Playdead, 2016). They have in common a mise en abyme of the player’s relationship to the machine through their avatar (and their respective relationship with GlaDOS in Portal, the Narrator in The Stanley Parable and with the second avatar in INSIDE). In these three games, the playable characters are the operators of a metadiscourse that – while constantly breaking the fourth wall to speak to the empirical player – actually constitutes the foundation of the narration itself.

[more ▼]La flexibilité, véritable outil de remise en cause des limites du temps de travail, gagne de plus en plus de terrain sur la table des négociations collectives tant au niveau macroéconomique que micro économique. La loi du 5 mars 2017 concernant le travail faisable et maniable s’inscrit dans cette tendance. Or, négocier le temps de travail et sa flexibilité n’est guère chose aisée. Ce travail porte, dès lors, tout particulièrement sur le processus parcouru par cet instrument d’action publique. Nous tenterons de comprendre les objectifs assignés à cette loi mais aussi, et surtout, leurs conséquences en termes d’interactions entre l’acteur politique et les partenaires sociaux. La complexité de tels processus décisionnels nous a amené à aller à la rencontre des acteurs y ayant pris part ; l’objectif étant de lever le voile sur cette obscurité liée à l’élaboration et à la négociation de ces nouvelles mesures de flexibilité du temps de travail.

[more ▼]During the last years, chemistry was involved in the worldwide effort toward environmental problems leading to the birth of green chemistry. In this context, green analytical tools were developed as modern Supercritical Fluid Chromatography in the field of separative techniques. This chromatographic technique knew resurgence a few years ago, thanks to its high efficiency, fastness and robustness of new generation equipment. These advantages and its easy hyphenation to MS fulfill the requirements of bioanalysis regarding separation capacity and high throughput. In the present paper, the technical aspects focused on bioanalysis specifications will be detailed followed by a critical review of bioanalytical supercritical fluid chromatography methods published in the literature.

[more ▼]A first type of Multifractional Process with Random Exponent (MPRE) was constructed several years ago by replacing in a wavelet series representation of Fractional Brownian Motion (FBM) the Hurst parameter by a random variable depending on the time variable. In the present article, we propose another approach for constructing another type of MPRE. It consists in substituting to the Hurst parameter, in a stochastic integral representation of the high-frequency part of FBM, a random variable depending on the integration variable. The MPRE obtained in this way offers, among other things, the advantages to have a representation through classical Itô integral and to be less difficult to simulate than the first type of MPRE, previously introduced. Yet, the study of Hölder regularity of this new MPRE is a significantly more challenging problem than in the case of the previous one. Actually, it requires to develop a new methodology relying on an extensive use of the Haar basis.

[more ▼]Reducing the use of insecticides is an important issue for agriculture today. Sowing wildflower strips along field margins or within crops represents a promising tool to support natural enemy populations in agricultural landscapes and, thus, enhance conservation biological control. However, it is important to sow appropriate flower species that attract natural enemies efficiently. The presence of prey and hosts may also guide natural enemies to wildflower strips, potentially preventing them from migrating into adjacent crops. Here, we assessed how seven flower traits, along with the abundance of pollen beetles (Meligethes spp., Coleoptera: Nitidulidae) and true weevils (Ceutorhynchus spp., Coleoptera: Curculionidae), affect the density of parasitoids of these two coleopterans in wildflower strips sown in an oilseed rape field in Gembloux (Belgium). Only flower traits, not host (i.e. pollen beetles and true weevils) abundance, significantly affected the density of parasitoids. Flower colour, ultraviolet reflectance and nectar availability were the main drivers affecting parasitoids. These results demonstrate how parasitoids of oilseed rape pests react to flower cues under field conditions. Similar analyses on the pests and natural enemies of other crops are expected to help to develop perennial flower mixtures able to enhance biological control throughout a rotation system.

[more ▼]This paper describes a robust and efficient method to obtain the steady-state, nonlinear behaviour of large arrays of electrically actuated micromembranes vibrating in a fluid. The nonlinear electromechanical behavior and the multiple vibration harmonics it creates are fully taken into account thanks to a multiharmonic finite element formulation, generated automatically using symbolic calculation. A domain decomposition method allows to consider large arrays of micromembranes by efficiently distributing the computational cost on parallel computers. Two- and three- dimensional examples highlight the main properties of the proposed method.

[more ▼]This paper presents a three-parameter kinematic theory (3PKT) for predicting the shear strength and deformation patterns of short coupling beams. The 3PKT approach is situated between simple and conservative strut-and-tie models and complex nonlinear finite element (FE) models. It is aimed at improving the strength predictions of strut-and-tie models while maintaining relative simplicity and clear physical basis. In addition, it is aimed at providing estimates of the ultimate deformations in coupling beams which are typically calculated with FE models. While FE models use a large number of degrees of freedom (DOFs) to describe the deformation patterns in coupling beams, the 3PKT is based on a kinematic model with only three DOFs. In addition to kinematic conditions, the 3PKT also includes equilibrium equations and constitutive relationships for the mechanisms of shear resistance in short coupling beams. The paper presents the formulation of the 3PKT and compares its shear strength predictions to results from tests, FE simulations, and strut-and-tie models based on the fib Model Code 2010. It is shown that the 3PKT approximates well the predictions of the FE models while the strut-and-tie model produces significantly lower strengths.

I start by examining some texts related to the awareness of the linguistic diversity and multilingualism in Greece, in Rome and in the Jewish-Christian thought, from Homer to Augustine. Next, after having studied the terminology in Greek and Latin, I consider some case studies of inter-linguistic communication and multilingualism in Greek and Latin authors. In the conclusion, I compare the ancient terminology of the multilingualism with some aspects of the modern terminology in French.
