We present recent developments on the role of the running coupling constant at the intersection of perturbative and nonperturbative QCD. A number of experiments show a smooth transition from small to large scales given by the four-momentum transfer in the reactions. This is at variance with perturbative QCD where the running coupling constant becomes infinite when the scale equals ΛQCD. Approaches using an effective coupling constant could help interpret the opposite trend of data as compared to standard perturbative QCD predictions. We give an overview of the role of the coupling constant in the procedure to match nonperturbative hadronic model to perturbative QCD and we propose an extraction of an effective coupling constant from inclusive electron proton scattering data at large Bjorken x.

In a previous work, J. Ponthot et al., Mec Comput, XXIV:441-454 (2005), have extended a large strain elastoplastic constitutive model based on hyperelasticity and multiplicative decomposition of deformation gradient tensor, to viscous case based on a contribution of the same main author . In this way a very useful tool has been obtained, able to deal with both rate dependent and rate independent problems. In this work a brief review of theoretical details is presented and numerical implementation of the model in a three-dimensional finite element code (SOGDE3D) is performed. The finite element code was developed for solving elastoplasticity in solids under large strains in three-dimensional space. A Newton Raphson scheme has been used to solve the non-linear consistency condition in order to compute the viscoplastic multiplier. An analysis of large viscoplastic deformation problems under plane strain condition are provided in order to test the proposed model. A comparison between two and three-dimensional versions of SOGDE code is achieved to validate the implementation and some results available in the literature helped to confirm the correct recovery of elastoplastic response by the viscoplastic model.

Sketching and prototyping of design concepts have long been valued as tools to support productive early stage design. This study investigates previous findings about the use and timing of use of such design tools. This study considers such tools in the context of team design projects. General trends and statistically significant results about “sketchstorming” and prototyping suggest that, in certain constrained contexts, the focus should be on the quality of information rather than on the quantity of information generated, and that prototyping should begin as soon as possible during the design process. Ramifications of these findings are discussed in the context of educating future designers on the efficient use of design tools. [less ▲]

While many studies have investigated histological changes occurring in cnidarians during bleaching, only a few have focused on continuing changes in tissues during the recovery period. Here, we examine the response of the sea anemone Aiptasia pallida to a transient elevation of water temperature combined with high illumination. Following 30h of exposure to stress conditions (33°C and 1900μE/m2.s), anemones show a significant reduction in their Symbiodinium concentration followed by a progressive recovery over 8 weeks. Histological analyses show an increase in cell proliferation in both ectoderm and gastroderm tissues one day following the stress. This increased proliferation seems to be sustained after 3 weeks before returning to normal after 8 weeks. Moreover, our results show a progressive increase in the number of ectodermal mucocytes over 3 weeks before returning to a normal level after 8 weeks. While the new cells formed in the gastroderm would most likely host new Symbiodinium, the fate of new cells in the ectoderm is still not completely understood. These new cells may contribute to the increased number of mucocytes which could eventually help shift the feeding mode temporarily to a heterotrophic state until restoration of the symbiosis.

The non-radial oscillations discovered by CoRoT (see e.g. de Ridder et al. (2009)) and by Kepler(see e.g. Bedding et al. (2010)) in thousands of red giants constitute a wonderful mine of information to determine their global characteristics and probe their internal structure. A. Miglio and J. Montalbán have presented in detail in this conference the seismic structure of red giants, the information hold by their oscillation frequencies, and how it can be used. An adiabatic analysis of the oscillations was sufficient at this level as the frequencies are mainly determined by the deep layers were the oscillatons are quasi-adiabatic. We consider here energetic aspects of non-radial oscillations in red-giants. Non-adiabatic models of solar-like oscillations are required to determine the theoretical amplitude and lifetimes of the modes. These parameters allow us to determine how power spectra are expected to look like, depending on the structure of the red giant. Comparison with the observed measures gives thus additional constraints on the models. [less ▲]

What is school ? Though this question is philosophical – if we keep in mind the historical tight bind between philosophy and teaching – it is nowadays considered exclusively as psycho-sociological matter. In educational relations (e.g. between children and their teacher), psychology is the vantage point : then pedagogy is above all psycho-pedagogy. At the same time we cannot today in Belgium deny a heavy, deep crisis in fundamental education any more. This situation may sanction pessimistic behaviors which often lead to inactivity and passivity. For my part, I would say this crisis is characterized by a current psychological aporia. So I must ask a new question : What should school be ? From the Kantian interrogation about the requirements of education – which is an art, not a science - I will draw some philosophical and pragmatic ways to overcome this psychological puzzle.

The Arabian Nights are universally, but only superficially known. The historical editions present an altered text, only the manuscripts being faithful to it. Amazingly enough, these are not much studied. My research deals with a group of manuscripts of the Arabian Nights, the so-called ZER (« Zotenberg’s Egyptian Recension »), supposedly dating to the end of the 18th or the beginning of the 19th century. I am both interested in the text (its structure, level of language, contents) and in the manuscripts themselves, considering them through a multidisciplinary approach. The first part of my research is a thorough codicological analysis of each manuscript of the group. Its results improve our knowledge of the manuscripts (among others, of the date of their copy) and of the text. A concrete example is given here, with the study of various watermarks found in the papers of the manuscripts. [less ▲]

In order to explore numerically the capability of solid-liquid phase change material (PCM) for heating indoor applications, melting of phase change material (PCM) was studied. The roof of the enclosure is filled with PCM (Hydrate salts PCM with melting temperature, Tmelt = Tcomfort =22 °C) on which are inserted heat pipes coming from the solar collector (heat source). The oom vertical walls are adiabatic. The power transferred from solar collector by water is fully dissipated in a PCM that filled a slab. The advantage of using this heating strategy is that the PCMs are able to store a high amount of heat generated by the solar collector and the sun rising on the slab without acting the HVAC system. Numerical investigations, based on a dynamic simulation, were conducted in order to analyze the thermal performance of the proposed system. It was found that, due to the PCM layer, there are less temperature fluctuations and comfortable leaving conditions are satisfied. The use of the HVACs systems will be remarkably reduced during January in Casablanca Morocco. [less ▲]

We consider the problem of learning high-performance Exploration/Exploitation (E/E) strategies for finite Markov Decision Processes (MDPs) when the MDP to be controlled is supposed to be drawn from a known probability distribution pM( ). The performance criterion is the sum of discounted rewards collected by the E/E strategy over an in finite length trajectory. We propose an approach for solving this problem that works by considering a rich set of candidate E/E strategies and by looking for the one that gives the best average performances on MDPs drawn according to pM( ). As candidate E/E strategies, we consider index-based strategies parametrized by small formulas combining variables that include the estimated reward function, the number of times each transition has occurred and the optimal value functions V and Q of the estimated MDP (obtained through value iteration). The search for the best formula is formalized as a multi-armed bandit problem, each arm being associated with a formula. We experimentally compare the performances of the approach with R-max as well as with e-Greedy strategies and the results are promising. [less ▲]

Physiologically based pharmacokinetic (PBPK) models are mathematical models that are largely based upon the physiological characteristics of the species and the biochemical properties of the chemical of interest. They quantitatively describe and predict the kinetics of pollutants inside the body and can be of major importance for risk assessment of chemicals in marine mammals. PBPK models which consist of five compartments (liver, blubber, kidney, brain, and the rest of the body) were made for selected polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in order to address the bioaccumulation of these compounds in tissues of harbour porpoises (Phocoena phocoena). Harbour porpoises have relatively long life spans, are common cetaceans in the North Sea, a heavily polluted area, and are known to be very sensitive to pollution. Models developed for all compounds (some PCBs and PBDEs) were evaluated using existing datasets from the literature and from analyses performed by GC-MS, the latter being obtained from stranded porpoises in the Black Sea and the North Sea over a period of 18 years (1990–2008) to assess spatial and temporal trends in bioaccumulation of the respective PCBs and PBDEs. We demonstrate that PBPK models are a feasible computational approach that can be used as a non-destructive tool for predicting the chemical pollution status of the marine mammals. [less ▲]

Sentence repetition is generally considered as a sensitive marker of specific language impairment (SLI). In the present study, we first examined whether the sentence repetition subtest of the L2MA-2 (Chevrie-Muller et al., 2010) makes it possible to discriminate between children with and without SLI. We then investigated the relevance of the multiple scores that can be computed in several linguistic domains in the clinical diagnosis of children with SLI. Twenty-two French-speaking children diagnosed with SLI and 22 chronological age matched children were asked to perform the sentence repetition task from the L2MA-2 test. Results indicate that this task is a sensitive clinical marker of SLI that makes it possible to discriminate between children with and without SLI. In addition, a factorial analysis indicates that two distinct factors can be dissociated when performing a sentence repetition task: a morpho-syntaxic factor and a lexico-semantic factor. Taken together, these results indicate that the sentence repetition task is a powerful tool when assessing language impairments in French language. [less ▲]

Recent years have seen an increase in the use of structural stainless steel, mainly owing to its aesthetic and architectural qualities alongside durability. Among stainless steels, ferritic grades are characterized by low nickel content resulting in a more cost-stable and economic material compared with austenitic stainless steels, allowing a balanced approach between economic and environmental aspects. As an introduction, this paper presents the recent research outcomes especially concerning the currently ongoing RFCS project “Structural Applications of Ferritic Stainless Steels”. Then, attention is paid to the advantages and challenges associated with the use of this material in recent construction projects in view of sustainability. Life cycle analysis is explained. The background of the new European standard EN 15804 is described, including Module D, which takes now into account the end-of-life phase. Life cycle inventories of stainless steel products (cold-rolled coils and quarto plate) are presented. Depending on the fraction of material recovered at the end of the lifespan, several potential impacts such as the Primary Energy Demand and Global Warming Potential are compared for four grades: 1.4301 (AISI 304) and 1.4401 (AISI 316) austenitic grades, 1.4016 (AISI 430) ferritic grade and 1.4462 (AISI 2205) duplex grade. The influence of the end-of-life credits and loads is underlined. [less ▲]

Nonlinearity is a frequent occurrence in engineering structures. It is at the origin of rich and complex dynamical phenomena that cannot be observed in linear structures. The analysis of the dynamics of nonlinear systems therefore warrants the development of rigorous and effective methods and is the focus of this presentation.

Non-local damage-enhanced MFH for multiscale simulations of composites

In this work, a gradient-enhanced mean-field homogenization (MFH) procedure is proposed for fiber reinforced materials. In this approach, the fibers are assumed to remain linear elastic while the matrix material obeys an elasto-plastic behavior enhanced by a damage model. As classical finite element simulations face the problems of losing uniqueness and strain localization when strain softening of materials is involved, we develop the mean-field homogenization in a non-local way. Toward this end we use the so-called non-local implicit approach, reformulated in an anisotropic way to describe the damage in the matrix. As a result we have a multi-scale model that can be used to study the damage process at the meso-scale, and in particular the damaging of plies in a composite stack, in an efficient computational way. As a demonstration a stack with a hole is studied and it is shown that the model predicts the damaging process in bands oriented with the fiber directions. [less ▲]

En janvier 2009, 27 maisons situées sur le littoral sud du Vietnam, dans la ville de Phan Thiet, zone très touristique à 200 kilomètres à l'est de Ho Chi Minh-Ville, se sont effondrées. Une centaine d'autres bâtiments étaient également menacés de disparition. Les médias internationaux ont ainsi relayé l’information « des centaines de soldats, de gardes côtes et de volontaires ont été mobilisés pour amasser des sacs de sable sur place et tenter de limiter les dégâts. En cause, l'érosion du littoral, grignoté par de fortes vagues. Selon les experts, le Vietnam et ses plus de 3.200 km de côtes font partie des zones les plus exposées aux effets du réchauffement climatique, qu'il s'agisse de l'élévation du niveau des mers ou de l'augmentation de la fréquence des typhons et inondations ». Il s’agit donc indéniablement d’une des conséquences du réchauffement climatique. Cet article montre comment, en utilisant la fonction multi dates Google Earth, il est possible de démonter cette argumentation et de mettre en évidence les vraies causes de ce rapide et inéluctable retrait des côtes au niveau de ce village de pêcheurs, à savoir la construction anarchique de la station balnéaire de Mui Ne, quelques kilomètres à l’est. La création de ce désormais haut lieu touristique est extrêmement récente, le premier établissement étant sorti de terre en 1994. Vu le succès croissant des plages de sable blanc, toute la côte a depuis été lotie sur près de cinq kilomètres. Mui Ne a donc modifié son espace pour accueillir les touristes occidentaux. Ainsi, les cocoteraies ont été abattues pour laisser la place à des cocotiers ne faisant plus office que de décor sur la plage, les liserons des sables ont été arrachés pour éloigner les puces de mer, le sable a été égalisé et les infrastructures hôtelières ont recouvert les dunes pour être en contact direct avec la plage. C’est ainsi tout un décor « exotique » qui est créé pour être conforme aux représentations des touristes occidentaux. La suite est connue d’avance : le fragile équilibre littoral est rompu et le bilan sédimentaire devient négatif. Entre 2006 et 2009, la plage d’une trentaine de mètres a totalement disparu. Or, la plage étant la raison d’être de ce lieu, il convient de la préserver à tout prix. Ainsi, les promoteurs immobiliers ont eu recours à la construction d’épis de plus de 100 mètres pour recréer de longues plages, artificielles cette fois, qui interrompent le transit sédimentaire. La dérive littorale est ainsi stoppée ce qui engendre la disparition des plages suivantes et l’effondrement des maisons de pêcheurs. Cette analyse montre clairement la rapide modification des paysages qui résulte d’une conversion économique locale non encadrée répondant aux processus de mondialisation. [less ▲]

Deficits in everyday life functioning are a core feature of persons diagnosed with schizophrenia. However, functional outcome is usually evaluated with questionnaires and performance-based assessments, all of which contain a number of limits. We developed a computerized real-life activity task (meeting preparation task) where participants are required to prepare a meeting room. Twenty-one individuals diagnosed with schizophrenia and 21 matched healthy controls completed the task. Patients were also evaluated with a cognitive battery and measures of symptomatology and functional outcome. Results showed that performance on the computerized task significantly differentiated patients and controls for a certain number of variables. These variables, combined into a composite score, were significantly correlated with both cognitive functioning and functional outcome. Moreover, this composite score significantly predicted 39% of functional outcome, whereas a cognitive composite score did not reach significance. In addition, when the meeting task composite score was combined with symptomatology and the cognitive composite score, these measures significantly predicted 70% of functional outcome. These findings suggest that the meeting preparation task provides a valid and significant indication of the level of everyday life functioning in patients with schizophrenia, and may be viewed as a valuable instrument in both an evaluation and remediation context.

The clinical examination and the ancillary tests at the disposal from the veterinarian may be poor diagnostics in horses suffering from subclinical inflammatory airway disease or in clinical remission of recurrent airway obstruction (RAO). The objective of this study was to determine whether the methacholine bronchoprovocation test -which is daily used for diagnosis of asymptomatic human asthma- may be used as an applicable and repeatable method for the diagnosis of an increased susceptibility to bronchospasm in horses. The test, realised on 8 horses (6 with RAO history and 2 controls) presents a good feasibility and significant repeatability. Dust exposure increased the bronchoreactivity, while it did not affect other clinical and functional parameters or inflammatory markers. In the future, the bronchoprovocation test could therefore find its place in clinicat practice for the detection of asymptomatic horses which are susceptible to develop bronchospasm in poor environmental conditions.

Numerical modelling is a very useful tool to predict the fire resistance of a structure, or to reproduce artificially what has happened during a real fire. SAFIR, a non linear computer code developed at the university of Liege-Belgium, is specifically written for modeling the behavior of structures subjected to fire. It allows a determination of the temperatures in the structure resulting from the fire and, in a subsequent analysis, determination of the successive positions of equilibrium of the structure until collapse. Ten steel hollow section columns filled with self-compacting concrete embedding another steel profile have been tested in the Fire Engineering Laboratory of the University of Liege - Belgium. SAFIR code 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 subjected to fire. [less ▲]

Non-linear elements are present in practically all spacecraft structures. The assumption of a (quasi-)linear structure is nevertheless adequate for structural analyses and design verification purposes in those cases where these structural non-linearities are relatively weak or not substantially activated by the mechanical environments encountered during the launch or during ground testing. However, when significant non-linear effects in spacecraft structures are no longer negligible then linear modal analysis will not be able to handle non-linear dynamical phenomena in an adequate manner: the development of a non-linear analogue of linear modal analysis becomes an urgent and important issue. The objective of this paper is to show that nonlinear normal modes (NNMs) represent a useful and practical tool in this context. A full-scale spacecraft structure is considered and is modeled using the finite element method. Its NNMs are computed using advanced numerical algorithms, and the resulting dynamics is then carefully analyzed.

The article analyses the differences in the treatment of the Afro-American slavery between the two latest editions of the famous Histoire des deux Indes, by Raynal and Diderot (1780-1820). The influence of the liberal ideology dominating the 1820 edition . The use of black music - field-hollers, gospel, blues, etc. - as a mean for intensifying and also softening the farm-work remains one of the most curious recommandations common two both editions. The observation concerning the "natural dispositions" of Black people for danse and music is original, compared wth what we learn from Eileen Southern's reserches and the testimonies of Nicholas Cresswell or Philip Vickers Fithian. The 1820 editions delivers a cruel picture of the other natural dispositions of Black people and of their future, considering thems as mere "machines" devoted to the increasement of colonial maket.

This paper presents a method for the measurement of LAI of wheat in situ. By using stereoscopic images a 3D map was computed. One colour image was segmented to identify plant regions and the 3D leaf area was computed on these regions. The result showed that the precision was about the same as for the reference measurements but required a lesser workload. [less ▲]

In the Luy de France valley at Labarthe-Argelos (Pyrénées-Atlantiques), a rescue excavation was carried out during spring 2009 on a surface of 2200 m2. The entire Final Neolithic remains were recovered from one single soil unit within the colluvium sequence at bottom of the slope. Nine hearths have been studied (see contribution of B. Nicolle, this volume), the pottery and lithic objects have been positioned in the stratigraphy and a delimitated area with abundant pottery sherds has been identified in close proximity to a small hearth. The pottery assemblage can be assigned to the Final Neolithic sequence of south-western France, within the third millennium. It forms, however, an original facies and contributes to fill an information gap in the Northern Pyrenean region. The lithic artefacts were made on flint and quartzite. Two radiocarbon dates consistent with the data assemblage stemming from the excavation place these occupations between 2600 and 2400 BC cal. The field data attribute Labarthe 2 to a series of small sites exhibiting subtle features not very deeply anchored into the ground that are known in the Bearn and the Landes regions. They are interpreted by a variety of hypotheses: stops during pastoral displacements, crossing points of the valley, places for specific activities (fishing, hunting?), etc. Their location, at the foot of a spur dominating the confluence may also be complementary of a possible settlement on top of the spur.
