Experimental dynamic substructuring is a means whereby a mathematical model for a substructure can be obtained experimentally and then coupled to a model for the rest of the assembly to predict the response. Recently, various methods have been proposed that use a transmission simulator to overcome sensitivity to measurement errors and to exercise the interface between the substructures; including the Craig-Bampton, Dual Craig-Bampton, and Craig-Mayes methods. This work compares the advantages and disadvantages of these reduced order modeling strategies for two dynamic substructuring problems. The methods are first used on an analytical beam model to validate the methodologies. Then they are used to obtain an experimental model for structure consisting of a cylinder with several components inside connected to the outside case by foam with uncertain properties. This represents an exceedingly difficult structure to model and so experimental substructuring could be an attractive way to obtain a model of the system. [less ▲]

The objective of the paper is to obtain the frequency response curves of nonlinear mechanical systems from broadband testing. The proposed approach consists in coupling an identification method with a continuation method. Specifically, the frequency-domain nonlinear subspace identification (FNSI) method is first used to derive an experimental model of the structure in state space from broadband measurements. The harmonic balance method coupled with arclength continuation then utilizes this experimental model to compute the frequency response curves of the system. The method is demonstrated using a numerical example. [less ▲]

The frequency-domain nonlinear subspace identification (FNSI) method has recently been successfully applied to large-scale nonlinear structures. One of the key features of FNSI is the nonlinear generalisation of the stabilisation diagram. However, as in linear system identification, the selection of the model order in the diagram is complicated by the presence of spurious poles, resulting from noise and modelling errors. Spurious poles have been shown to strongly perturb the estimation of the nonlinear coefficients. The present paper establishes a constructive procedure to discriminate between spurious and genuine poles. This procedure is derived in modal space and is based on a dominancy index and on model reduction techniques. It is demonstrated on a complete satellite structure possessing nonsmooth nonlinearities and high modal density. Spurious frequency variations in the nonlinear coefficients are proved to be effectively removed, significantly improving the quality of the overall identified model. [less ▲]

The European Commission’s White Paper on transport seeks to achieve an efficient and sustainable balance between the various transport modes. In this context, BRAIN-TRAINS is a project supported by Belgian Federal Government that deals with rail freight intermodality, approaching the problem from an interdisciplinary perspective. BRAIN-TRAINS will be able to answer the transition involved in transportation in Belgium. To analyse the sustainability impact of rail freight intermodality in Belgium, the life cycle assessment methodology will be used. The rail freight system is divided in this paper into rail operation, rail equipment and rail infrastructure. This paper shows the methodology to calculate the transport emissions related with the energy consumption during the rail operation. [less ▲]

Though few eighteenth-century houses in Liège have conserved their original wooden furniture or fittings, archival research reveals that these elements constituted a key aspect of the domestic interior. The present work draws largely on a series of public announcements known as Rendages proclamatoires which concerned property belonging to orphans sold by public auction, that exist. From 1697 to 1765, these sources provided descriptions of 257 houses situated within the city walls. The wooden furniture and fittings of eighteenth-century Liegerian houses can clearly be seen to be pertain to far more than the sole history of joinery: they also tell the story of Liege’s domestic living spaces in terms of social structure and cultural change. As such they eloquently illustrate the fact that it is only by taking into account the Old Regime’s conception of architecture as a total entity that we can today work towards establishing an increasingly just, coherent and complete understanding of ancient edifices.

At the end of 2013, a new Common Agricultural Policy was defined at the European level, including the implementation of the so-called “green payment”, which obliges farmers to respect three new conditions in order to get financial support through direct payments. The year 2015 being the first implementation year, the consequences on Walloon agriculture are examined. It appears that 50% of Walloon farmers are not obliged to practice crop diversification, while 16% are obliged to have at least two crops on their arable land and 33% are obliged to have at least three crops on their arable land. Less than 1% does not respect the new diversification rules. Concerning the obligation to have at least 5% of ecological focus area on the arable land, it appears that 54% of Walloon farmers are in conditions not to be obliged to respect the measure. When they implement the measure, the percentage of ecological focus areas in arable land reaches 6.9% as a mean and 2.4% do not reach the requested 5%. Finally, it can be said that the green payment does not represent a big constraint for Walloon farmers, though eventual economic consequences are still to be precised, while environmental benefits are strengthened.

Recent researches have stated the fast deployment of IPv6. It has been demonstrated that IPv6 grows much faster, being so more and more adopted by both Internet service providers but also by servers and end-hosts. In parallel, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels transparent to traceroute probing. However, these studies focus only on IPv4, where MPLS is strongly deployed. In this paper, we provide a first look at how MPLS is used under IPv6 networks using traceroute data collected by CAIDA. At first glance, we observe that the MPLS deployment and usage seem to greatly differ between IPv4 and IPv6, in particular in the way MPLS label stacks are used. While label stacks with at least two labels are marginal in IPv4 (and mostly correspond to a VPN usage), they are prevalent in IPv6. After a deeper analysis of the label stack typical content in IPv6, we show that such tunnels result from the use of 6PE. This is not really surprising since this mechanism was specifically designed to forward IPv6 traffic using MPLS tunnels through networks that are not fully IPv6 compliant. However, we show that it does not result from non dual-stack routers but rather from the absence of native IPv6 MPLS signaling protocols. Finally, we investigate a large Tier-1 network, Cogent, that stands out with an original set-up. [less ▲]

Bulk (RE)BCO superconductors are able to trap record magnetic fields and can be used as powerful permanent magnets in various engineering applications such as rotating machines and magnetic bearings. When such superconducting (SC) “trapped field magnets” are combined to a ferromagnetic (FM) disc, the total magnetic moment is increased with respect to that of the superconductor alone. In the present work, we study experimentally the magnetic behaviour of such hybrid FM/SC structures when they are subjected to cycles of applied field that are orthogonal to their permanent magnetization, i.e. a “crossed-field” configuration. Experimental results show that the usual “crossed-field demagnetization” caused by the cycles of transverse field is strongly reduced in the presence of the ferromagnet. [less ▲]

The international conference « encore l'architecture – encore la philosophie » is an initiative of the GERPHAU lab, research group for Philosophy, Architecture, Urban (Architecture School of Paris La Villette, UMR 7218 CNRS-Lavue), in partnership with Cité de l'architecture et du patrimoine, UMR-Lavue (Laboratoire Architecture, Ville, Urbanisme, Environnement) and philAU (a scientific thematic network : Philosophy, Architecture, Urban). This conference is the first ARENA conference (Architectural Research in Europe Network Association), a shared platform that aims to promote, support, develop and disseminate high-quality research in all fields of architecture in the widest sense. The network already includes researchers from leading European architecture schools. Synopsis. In Paris in 1987, a first event was held to celebrate the meeting of two disciplinary fields, entitled “Mesure pour mesure, architecture et philosophie”. Architects and philosophers were invited to discuss together how philosophy could capture better what determines architecture itself. Now, on the occasion of a new international conference, the GERPHAU Lab seeks to restate and refresh the question of the meeting of architecture and philosophy, by asking: what still remains today of our cross-over practices? ENCORE L'ARCHITECTURE, ENCORE LA PHILOSOPHIE. To build together these reflections about the future of our respective practices, why don't we hold to the hypothesis that our recent histories, in architecture as well as philosophy, could be written through the addition of a few prefixes? In linguistics, a prefix does not only serve the formation of a new word: it also regenerates the question of the meaning of the word. It is a discursive invention and its real strength lies in its ability to engage a new type of relationship with the world. Re-, alter-, eco-, co-, bio-, etc., these prefixes have clung to both our discourses as well as our disciplines. But in what way do they question the meaning of our practices? In archi-tecture as in philo-sophy, how do these successive re-definitions put the fundamentals into question, and how do they disturb their alleged unity inherited from Ancient Greece? And, moreover, how does the over-use of prefixes help us to understand what still makes sense in philosophy, or what still makes sense in architecture? The key issue of this conference, ‘Encore l'architecture, Encore la philosophie’, will be to trace backwards the stream of architectural and philosophical ideas through the thematic of the prefix as constituting a form of narrative. The conference will aim to trace the paths of their development, and other influencing factors, so as to return to those meetings between architecture and philosophy which already have oriented, re-oriented and sometimes dis-oriented our speech. It will be a meeting at which we invite participants to retell the story of our disciplines in order to grasp what it is still unique today about our practices. [less ▲]

A new Common Agricultural Policy was defined in 2013, with a new structure for direct payment. In Wallonia, the government implemented the following scheme: 30% for the green payment, 29.9% for the basic payment, 17% for the additional payment for the first 30 ha, 1.8% for young farmers and 21.3% for couple payments. Due to convergence, the mean support through direct payments will decline from 21,900 € in 2014 to 19,283 € in 2019. The number of losers will be equivalent to the number of gainers. Regions where cereals and sugar beet are produced will lose the most, where the region suitable for cattle raising will gain somewhat. There will be a better distribution of direct payments among farmers: the Gini index will decline from 0.55 to 0.49. The highest negative impact on income will occur for the specialties “green crops”, “crops and dairy cattle” and “crops and non-dairy cattle”: the least negative impact will be observed within the specialties “dairy cattle”, “meat cattle” and “dairy and meat cattle”. The reform will be more profitable for the farms from 30 to 50 ha and will mainly impact the largest farms. Finally, the CAP reform implemented in Wallonia guarantees a smooth evolution to 2020.

In 2012, the Walloon Government ordered the Walloon Institute for Prospective, Evaluation and Statistics (IWEPS) to calculate five indexes in order to guide and evaluate the public actions, together with the GDP. The index for the conditions of human well-being (CWBI) is presently the first step in the elaboration of the wellbeing index. The methodology is the one used by the Council of Europe. Actually, the CWBI is calculated by using 60 basic indicators, gathered into 8 families. After normalisation, the CWBI is the arithmetic mean of the 60 basic indicators, each of them having the same weight. The CWBI was calculated for the 262 communes of Wallonia and varies from 0.428 to 0.674, with a regional mean of 0.572. An opposition between urban and rural communes clearly appears, the last ones having the best scores. Communes along the borders of Germany and Luxemburg have the highest indexes, while communes in the old industrial areas have the lowest scores. Employment, income, family relations and security are the factors which are the most narrowly linked to the CWBI. At the communal level, social and security expenses per capita have a significant and negative correlation coefficient with the CWBI. In the future, in order to elaborate a finer index, new data, up to now not directly available, will be collected at the communal level, about quantitative and qualitative aspects. [less ▲]

Structurally heterogeneous forest ecosystems are generally considered to be more productive, resistant and resilient to future changes than simplified ones. The quantity of solar radiation available to trees and the vegetation layer has been suggested to be a central driver among the possible mechanisms proposed to explain a greater productivity of heterogeneous stands. The idea that trees of different species and sizes can occupy complementary positions in space has led to the hypothesis that interception of radiation could increase in mixed and multi-layered forest stands, which should thus lead to an increase in production. In addition, the long-term sustainability of structurally heterogeneous forests with multiple coexisting species can only be ensured if the variability in light availability in the understory is sufficient for all species to be able to survive, grow and reproduce. However, better occupancy of canopy space should lead to reduced variability in understory light conditions. In this study, we investigate whether increasing overstory heterogeneity results in greater light capture by trees and greater variability in understory light. Greater light capture has been suggested as a possible explanation for the overyielding of complex stands and the greater variability in understory light as a mechanism for continuous recruitment of juvenile trees of various species. Based on allometric relationships developed in previous studies, we modeled the three-dimensional structure of forest stands (50 x 50 m) with 3 typical forest structures (single-layered, multi-layered and reverse j-shaped), 10 forest compositions combining beech, oak, fir and pine, 3 levels of basal area, and a fixed mean tree diameter (Figure 1). We predicted understory light conditions using the forest light interception model SAMSARALIGHT. The importance of each factor on understory light availability and variability was analyzed with three-way analyses of covariance. We found no evidence that increasing compositional or structural heterogeneity reduces understory light transmittance or increases tree light capture. Understory light transmittance in mixed stands was always intermediate between that is corresponding pure stands of the species involved in the mixture. Moreover, light transmittance slightly increased with increasing heterogeneity in forest structure. Stands composed of a single homogeneous tree layer transmitted less light than stands with two or more tree layers or stands composed of two or more species. Stand composition had the strongest influence on understory light in our simulations. Stand density was the second most important factor while heterogeneity in tree size had little effect. Compositional heterogeneity increased the variability in understory light conditions in some cases such as in fir-pine mixtures but adding beech to mixtures with oak generally limited variability in understory light, except in stands with very low basal area. Size inequality therefore increased understory light variability little and mainly in pure stands. The advantage of heterogeneous forest stands seems to lie in opportunities for the natural regeneration of various species to benefit from a diversity of light conditions in the understory rather than in opportunities to enhance light capture by the overstory although this effect depends on tree species composition.

Recycling is not a luxury or a fashion but a necessity that comes from a very simple fact: we live in a limited world. Contrary to what we have believed for a long time, our human activity is not infinitely expandable but limited in terms of energy, natural resources, space or simply adaptation capacity of nature. From this finding and that awareness must result a behavior that essentially is based on the respect we have for ourselves and therefore for nature (to take car and not to convert). Recycling, reuse, re-use, regeneration or recovery are behaviors that aim to minimize the energy used, to take maximum advantage of the material and to reduce the risk of pollution during the manufacture, use or disposal of these materials. In general, this means that it is desired to delay as much as possible when an object becomes waste. This requires a vision of the life of material or object (Life Cycle Assessment), in which a balance sheet is prepared at every stage of life - from raw material extraction, manufacturing, processing, recycling and elimination. Additionally to materials known as "natural" or “bio-based”, the construction industry increasingly incorporates these alternative materials, even if not without some psychological, normative and technical reservations. As a significant source of pollution (CO2, solid waste, ...), construction is a major reservoir for recovery of waste and industrial by-products: alongside the traditional production process of construction materials and the resurgence of bio-based materials, recycled materials also contribute to the development of materials for future.

During the last years, organic farming considerably developed in Belgium. In 2014, it represented 5% of the total agricultural area and 4.5% of the number of farms [1]. Organic farming is mainly developed in Wallonia where its share of the agricultural area exceeded 10% in 2014. Pastures for bovine production (meat and milk) and general crops (mainly cereals) are the most common cultivated areas. Poultry, eggs and vegetables recorded the highest increases. This success is partly the result of a strategic plan for the development of organic farming in Wallonia towards 2020 [2] and of remarkable financial support for the farmers [3]. More than 8,400 food and non-food organic products are available for the consumers. The number of prepared and processed food products is increasing. The market share of food organic products is still low, but continuously increasing: 1.3% in 2008, 2.3% in 2014. Remarkably, the expenses for organic food products still increased by 50% in 2014, while the total expenses for common food products declined for the first time since many years. The most important expenses per capita concern dairy products (5.40€), vegetables (4.74€), fruits (3.71€) and bovine and pork meat (2.84€). The main locations where food organic products are bought are supermarkets (45%) and specialized shops (31%). Families with children and high income and retired people with high income count for more than 5% of the expenses for organic food, while single persons aged over 40 are the category which spend the highest share of its income (4.1%) for organic food. In such conditions, organic farming is an important topic of the strategic plan for sustainable development presently proposed for discussion to the Walloon citizens. [less ▲]

In the context of energy demand side management (EDSM) and heat storage in aquifers, the design and functioning of aquifer thermal energy storage (ATES) systems have strong interconnections with the geology of the site which may be complex and heterogeneous, making predictions difficult. In this context, we developed a subsurface monitoring methodology to better characterize heat transfer in the subsurface with the help of 4D electrical resistivity tomography (ERT), multiple hydrological measurements in wells, and a short-term heat storage experiment conducted for the purpose in a confined alluvial aquifer. Results clearly show the ability of ERT to delimit the thermal plume growth during injection, the diffusion and decrease of temperature during storage, and the decrease in size after heat recovery. Energy balance shows that up to 70% of the energy can be easily recovered with an adapted strategy in the context of DSM. Short-term heat storage in alluvial aquifer is efficient and ERT is a valuable tool to image and estimate the temperature distribution in the subsurface. [less ▲]

Recent advances in agent-based micro-simulation modelling have further underlined the importance of a thorough full synthetic population procedure to guarantee a correct characterization of the true population. We propose an integrated approach including Markov Chain Monte Carlo (MCMC) simulation and profiling based methods to catch the complexity and the diversity of agents of the true population through representative micro samples. The population synthesis method is capable of building the joint distribution of a given population with its corresponding marginal distributions (e.g. age, gender, socio-professional status etc.) using complete, partial conditional probabilities or both of them at the same time. Particularly, the estimation of socio-demographic variables and characterization of daily activity-travel patterns are included within the framework. Data stemming from the 2010 Belgian Household Daily Travel Survey (BELDAM) are used to calibrate the modelling framework. We illustrate that this framework catches in an efficient way the behavioral heterogeneity of travelers. Furthermore, we show that the proposed framework is adequately adapted to build large scale micro-simulation scenarios of transportation and urban systems. [less ▲]

In this paper, we propose an integrated framework to estimate the indirect economic impact due to flood risk in Belgium. By taking into account the land-use change and different scenarios of climate change, the economic impact can be estimated at the micro-scale level using an Input-Output (I-O) approach. I-O is an econometric model that represents the structure of an economy in the form of a Production-Consumption (P-C) matrix. From a physical point of view, it corresponds to commodity flows between different sectors classified according to the NACE code. This approach is implemented to describe and to better understand the propagation of higher order damage through the entire economic structure. This tool can be used to take strategic decisions in the case of transport and land-use policies within vulnerable areas. [less ▲]

Drowsiness is a major cause of accidents, in particular in road transportation. It is thus crucial to develop robust drowsiness monitoring systems. There is a widespread agreement that the best way to monitor drowsiness is by closely monitoring symptoms of drowsiness that are directly linked to the physiology of an operator such as a driver. The best systems are completely transparent to the operator until the moment he/she must react. In transportation, cameras placed in the passenger compartment and looking at least at the face of the driver are most likely the best way to sense physiology related symptoms such as facial expressions and the fine behavior of the eyeballs and eyelids. We present here the new database (available on http://www.drozy.ulg.ac.be) called DROZY that provides multiple modalities of data to tackle the design of drowsiness monitoring systems and related experiments. We also present two novel systems developed using this database that can make predictions about the speed of reaction of an operator by using near-infrared intensity and range images of his/her face.

Fuel poverty refers to a situation in which an individual or household is not able to meet their basic energy needs. Fuel poverty is currently growing in the European Union. Research in this field is often limited to the assessment of the current risk of fuel poverty based on energy consumptions due to housing. Urban sprawl generates a significant increase in energy consumption related to daily mobility, which generates energy poverty related to transportation needs. This article presents a methodology for modeling the current and future energy poverty of households in Europe on the basis of energy consumptions due to housing, to daily mobility and their combination. Indicators for fuel poverty and transport poverty will be based on Hills’ method, which is widely recognized internationally for fuel poverty assessment and which takes into account two thresholds: energy expenses of households and their available residual income. This article will outline the spatial modeling process of energy costs due to dwellings and mobility thanks to the coupling of a GIS tool, cadastral datasets, existing methods for the assessment of buildings and transport energy consumptions and updated databases (EPB certificates, detailed mobility surveys, data from smart meters, mobile phones and GPS). Different scenarios will be selected to predict the evolution of fuel and transport poverty until 2040 on the basis of national and European prospective studies or, alternatively, based on the historical evaluation of some key parameters and their extrapolation. The evolution of built-up areas will be model thanks to the multinomial logistic regression model (MLR) that enables to visualize the consequence of different urban densities expansion. The different parameters that will influence the evolution of fuel and transport poverty until 2040 will be highlighted (climate change, urban expansion, fuel prices, energy performance of buildings and vehicles, etc.).

In this paper, the effect of traveler's nationality on daily travel time expenditure is assessed using data stemming from the 2010 Belgian national household travel survey. In particular, different (zero-inflated) negative binomial models were estimated to isolate the effect of nationality, after controlling for other contributing factors such as socio-demographics, residential characteristics, transport options and temporal characteristics. The results indicate that, even if one controls for a series of other influencing factors, nationality plays a significant role in differences in travel time expenditure. This finding is especially relevant in the development of policy packages that are targeted to tackle social inequalities. From a methodological perspective, different methodological options, i.e. two weighting schemes and two bootstrap solutions, were presented to provide sufficient support for the conclusions. In order to generalize the results in further studies, an oversampling of travelers with a different nationality is strongly recommended. Future research should focus more on the underlying psychological constructs of why ethnic and cultural differences persist, even if one accounts for other determinants. [less ▲]

Energy performance of buildings generally assesses the energy consumption of buildings such as heating, domestic heat water, ventilation systems... However, this approach is based on the first law of thermodynamics and considers only the quantity of energy used without considering its “quality” and leads to a lack of information about the energy conversion processes. This is particularly true in the new low-energy buildings where sometimes high temperatures sources are used to meet low-temperature needs. The exergy analysis of a system, based on first and second thermodynamic laws, can be used to overcome this. In this work, it is proposed to compare the energy and the exergy consumption of several kinds of buildings to determine the best systems in terms of energy and exergy needs. The energy demand calculations are performed using the official software available in Belgium and some assumptions are implemented to consider the exergy approach. As exergy calculations require a reference state, some different climatic conditions are also investigated. Finally, some conclusions are discussed to rank the sources of energy and their related exergy losses. [less ▲]

The increased risk of breast cancer and thromboembolism in women who take Hormone Replacement Therapy (HRT) currently is a major public health problem. The discovery of novel molecules with better safety profile would provide useful advances for patient care. Estretrol (E4) appears as a promising candidate for HRT. Indeed, in contrast to current treatment containing ethinyl estradiol or estradiol (E2), E4 has a minimal impact on liver cells activity supporting a decreased incidence on thromboembolic events. In preclinical studies, E4 has been effective against the main symptoms of menopause such as hot flushes, vaginal atrophy, and osteoporosis, from a starting dose of 0.3 mg/kg/day. The aim of this study was to define the impact of E4 on breast cancer development when it is used at concentrations effective for menopause symptom relief. Treatment of estrogen receptor (ER)-positive breast cancer-developing mice (MMTV-PyMT) with several concentrations of E4 has shown that 0.3 mg/kg/day E4 did not increase tumor development and metastasis dissemination. However, at 3mg/kg/day, E4 increased the growth of hormone-dependent tumors and their metastatic dissemination in ovariectomized and intact mice. This effect was similar to the one observed with E2 used at 0.08 mg/kg/day. In an in vivo model of ER-negative tumors, we observed that 3mg/kg/day E4 improved tumor growth by increasing angiogenesis, and subsequently decreasing necrosis and tumor hypoxia. In contrast, 0.3 mg/kg/day E4 did not induce any of these effects on ER-negative tumors and tumor microenvironment. In conclusion, we have shown that 0.3 mg/kg/day E4, already reported to prevent menopause symptoms, does not increase breast tumor growth, metastasis dissemination, and angiogenesis. However, similarly to E2, higher concentrations of E4 are pro-tumorous. These results support that E4, if it is used in strictly controlled clinical applications, could have no or only limited impact on breast cancer. [less ▲]

District heating networks (DHN) are generally considered as a convenient, economic and environmental-friendly way to supply heat to a large amount of buildings. Some modelling technics are required to consider the dynamic behaviour of district heating network to design them correctly, spare investment costs and limit the heat losses related to the use of a too high operating temperature. For the same reasons, the DHN control or retrofit of installations also requires the assessment of the DHN dynamic behaviour. To achieve this, the heat transport in DHN, which is one of the key issues in the behaviour of a whole centralized heating system, has to be correctly modelled. Previous work evidenced current limitations of one dimensional finite volume method to model heat transport in pipes and proposed an alternative method considering the thermal losses and the inertia of the pipes. The present contribution intends to experimentally validate this model on a test rig facility available in the Thermodynamics laboratory of the University of Liège (ULg, Belgium) and on an existing district heating network. For both experimental facilities, the current model shows good agreement between experimental data and simulation results for a large range of water velocities. Moreover, it is shown that the thermal inertia of the pipe has a significant influence on the outlet pipe temperature profile. [less ▲]

In Bolivia 44 % of the people living in rural areas do not have reliable access to electric energy. This is due to a combination of unfavourable geography and the lack of economic resources to achieve the necessary infrastructure. In this context, the main goal of this study is to evaluate the economic and technical feasibility of micro-grids including photovoltaic panels (PV), batteries systems and the possible inclusion of diesel generators for off-grid applications. To that aim, a linear optimization model was developed within the Pyomo framework in order to optimize both the installed capacities and dispatch of the PV, battery and diesel sub-systems. The defined objective function is the net present cost. The exogenous inputs of the optimization are the typical demand and solar irradiation of a region of Bolivia in order to achieve results close to real Bolivian systems. Results indicate that due to the high levels of subvention to hydrocarbons, the PV and Li-Ion technology are not yet competitive with a diesel generator for the electrification of rural areas. On the other hand a sensitivity analysis is performed and proves that if the government decide to stop part of the subvention or shared it between conventional and non-conventional sources, the PV becomes competitive and the Li-Ion batteries enter the market around 2020.

L’objectif de cette recherche est d’examiner le développement des habiletés métacognitives au cours de l’enfance, en prêtant une attention particulière aux variables et processus impliqués dans l’acquisition des connaissances concernant le fonctionnement général de la cognition. Précisément, le but de cette étude est de démontrer l’impact des atteintes exécutives résultant d’un traumatisme crânien sur le développement des connaissances explicites des enfants en métamémoire. Dans ce but, 22 enfants (âgés de 7 à 14 ans) ayant subi un traumatisme crânien modéré à sévère ont été recrutés et divisés en deux groupes en fonction de la gravité de leurs atteintes exécutives (déterminée par le score obtenu à une épreuve d’inhibition, de flexibilité et de mémoire de travail). Au total, dix enfants constituaient le groupe ne montrant pas d’altération du fonctionnement tandis que douze enfants constituaient le groupe montrant des altérations significatives du fonctionnement exécutif. Les deux groupes de patients étaient équivalents à tous les autres niveaux du fonctionnement cognitif. Chaque patient a également été apparié à deux enfants contrôles (n = 44) en fonction de l’âge et du niveau socio-économique. Conformément à l’hypothèse généralement avancée dans la littérature concernant le rôle des fonctions exécutives dans l’apprentissage des connaissances métacognitives au cours de l’enfance, les résultats montrent une différence significative entre les deux groupes de patients au niveau des scores à l’échelle de métamémoire. De même, de moins bonnes performance à l’échelle de métamémoire sont observées pour le groupe de patients démontrant une atteinte exécutive comparativement au groupe d’enfants contrôles. Aucune différence n’était observée entre le groupe de patients ne démontrant pas d’atteinte exécutive et le groupe contrôle. Ces différents résultats suggèrent l’implication des fonctions exécutives dans l’acquisition des connaissances en métamémoire au cours de l’enfance. L’implication de ces résultats pour la prise en charge des patients souffrant de déficits exécutifs sera discutée. [less ▲]

Assessing social impacts of various products, services and human activities has achieved an increasing interest worldwide. The nature of sustainability of biobased industries from a social point of view is how and to what extent they are perceived by society, and how various societies take advantages from such activities. However, an important issue is that social factors are not usually easy to be quantitatively analyzed and although the social impacts might be very remarkable, especially at the local scale, they have been not possible to be investigated in the majority of impact evaluations in the past. Despite the existence of many different methodologies towards Social Life Cycle Assessment (SLCA) to address social impacts of various businesses and industries, most of them impartially address social performances of an industry. The aim of this paper is to highlight the main criteria that need to be taken into account in SLCA approaches for identifying the social indicators and impacts of biobased industries that is a timely topic worldwide toward climate change mitigation goals. Accordingly, considering the general approach of SLCA and particularly its inventory analysis phase for impact categories and indicator determinations, the paper provides an overview of the existing guidelines and frameworks for identifying social indicators and impact categories associated with bio-industries. In conclusion, main impact categories and indicators formulated in the existing frameworks applied to biobased industries are demonstrated as a basic set of applicable elements of social dimensions in evaluating bio-industries’ sustainability when conducting SLCAs. The state of the art for this study mainly includes leading journal articles, international reports and conference papers up to and including 2016 on SLCA in biobased industries. According to the reviewed frameworks in this study, quantitative, midpoint and site-specific data are the main elements taken into account when collecting the data for biobased product social impact assessment. This study also reveals that although SLCA is in its early steps of development and despite in numerous cases, conducting a comprehensive SLCA is not yet feasible, it has been considered to have substantially promising methodological attributes that can help policymakers and other stakeholders to quantify and assess sustainability of bio-industries from the social perspective. Recommendations for further research work concerning SLCA in bio-industries are also presented. [less ▲]

Le présent projet de communication propose une étude sur la manière de représenter la violence ainsi que son instrumentalisation à des fins personnelles dans des actes relevant de la pratique notariale aux XVIIe et XVIIIe siècles à Liège. L’analyse de ces sources est novatrice pour une histoire de la criminalité. En effet, les historiens se sont avant tout centrés sur les archives des cours judiciaires. Il semble cependant que les populations d’Ancien Régime n’allaient pas systématiquement devant le juge pour régler leurs conflits. Ainsi des accords, qui ne seraient sans doute jamais parvenus à la connaissance de l’historien par la seule étude des archives criminelles, émergent dans les actes relevant de la pratique notariale. Outre ces accommodements clairement identifiés dans les minutes, les populations d’Ancien Régime se déplacent également devant notaires pour que ceux-ci retranscrivent, plus ou moins fidèlement, le récit subjectif d’un évènement vécu. Ces déclarations criminelles seront ensuite, selon le choix du comparant, enregistrées ou non au greffe. En effet, cette trace d’accusation ou de témoignage ne parvient pas systématiquement aux autorités. Tout dépend de l’évolution du conflit et parfois le simple déplacement chez le notaire pousse la partie adverse à s’accommoder avant le passage en justice. Ces déclarations criminelles constituent des sources particulièrement intéressantes pour observer la psychologie, les perceptions et les interprétations de la violence des victimes et des agresseurs. Nous proposons ici d’étudier les stratégies discursives mises en œuvre lors de la passation d’une déclaration devant le notaire et sur ce qu’elles révèlent de la société qui les produit. En effet, ces témoignages constituent une véritable mise en scène de la violence, qui est instrumentalisée afin d’obtenir gain de cause lors d’un conflit. Comment les comparants s’y prennent-ils ? Quels sont les topoï les plus souvent utilisés ? Observe-t-on une évolution de ces discours entre le XVIIe et le XVIIIe siècle ? Cette analyse permettra de mettre en lumière la manière dont la société attribuait différents seuils de gravité à des actes violents, leurs circonstances aggravantes et comment ces représentations de la société étaient sciemment utilisées par les intervenants pour déconstruire la gravité de leurs actes. Enfin, étudier la violence et les discours des personnes impliquées permet également une meilleure compréhension de phénomènes sociaux que nous proposons de souligner, comme l’importance de l’honneur et sa place essentielle dans la société d’Ancien Régime.

Soil compaction is a complex mechanism which results in a decrease of soil porosity and an increase of soil strength. Such effects may reduce crop yield since they are harmful for root growth, germination, mesofauna and bacterial life. Soil compaction may also reduce hydraulic conductivity which increases the risk of runoff, contamination of surface water, erosion and emission of greenhouse gases due to anaerobic processes. In the context of sustainable agriculture, it is crucial to characterise the impact of the agricultural techniques on the compaction state in the arable layer due to machine traffic. For this purpose, Soil samples were taken in a Luvisol at different depths, on plots under longterm reduced tillage (RT) and conventional tillage (CT). The impact of wheel traffic on the physical properties of the soils was also studied. The experimental approach consists in measuring traditional macroscopic soil properties such as bulk density and precompression stress, and combining them with pore size distribution obtained by mercury intrusion porosimetry. Automatic cone index measurements were initially performed to map the soil resistance and easily identify the sampling depths. The measurements revealed a plough pan at 30-cm depth under both CT and RT. Nevertheless, the subsoil under RT showed pieces of evidence of a natural regeneration process of the microporosity. The impact of wheel traffic was studied in RT and CT plots. It was shown that the passage of heavy machine such as beet harvester coupled to water content close to the optimum proctor is clearly unfavourable in terms of compaction. The measurements revealed large modifications of soil structure in the topsoil of CT, whereas the soil structure slightly changes through depth. However, the latter remains the more problematic case since the soil will not be loosened by tillage anymore, resulting in strongly compacted soil years after years. In addition to the experimental approach, numerical modelling was used in order to predict the soil compaction. A finite element method was used and the soil behaviour was modelled by an elastoplastic law (modified Cam-Clay model). The model parameters were calibrated from the experimental measurements. The simulations allowed to compare the porosity and the surface deformation after wheel traffic with the experiments. The variations of machine weight and tyre pressure were numerically studied and it was showed that the machine weight has an influence in the topsoil and the subsoil, whereas the tyre pressure affects only the topsoil.

La réparation et le renforcement des structures existantes en béton comptent parmi les plus importants défis auxquels les ingénieurs civils sont confrontés aujourd’hui et qu’ils devront relever dans les années à venir. Les préoccupations actuelles concernant le développement durable favorisent la réfection au détriment de la construction neuve et ne peuvent que renforcer cette tendance. Des efforts concertés de la part des scientifiques et ingénieurs sont encore nécessaires afin d’améliorer la conception des réparations en béton et d’en assurer la qualité et la fiabilité attendues. L’un des aspects essentiels de la durabilité des réparations en béton et des revêtements ou traitements de surface est la qualité de l’adhérence entre le matériau de réparation et le béton existant. Le présent article résume les principales conclusions de travaux réalisés en collaboration en vue d’identifier les facteurs influençant l’adhérence des réparations (la rugosité, le degré de saturation et la carbonatation du substrat) et l’évaluation de celle-ci en conditions in situ (type de chargement, alignement de l’appareil). Sur la base des résultats recueillis, des recommandations ont été émises dans un guide du USBR [less ▲]

Considering its potential impacts on development, biobased industries require to be assessed according to the positive and negative effects they can bring to the society. Typically, the implications of biobased industries are considered in terms of economic, environmental and technical indices while social factors are usually neglected in the majority of impact assessments. This is mainly due to the fact that social issues are not easy to be quantitatively analyzed, measured and monitored. Indeed, the following issues need to be addressed: (i) how the social dimension is understood from different stakeholders’ perspective; (ii) how the social pillar can be properly integrated into sustainability evaluation methodologies which are mainly focused on environmental performance and (techno)-economic assessments of biobased industries. This review paper aims to answer these questions firstly through identifying the main social impacts and indicators of the biobased industries at local level in order to find an answer for the second question by analyzing and comparing the current methodologies for assessing social impacts in bioindustries. These methods mainly include Social Impact Assessment (SIA), Socio-economic Impacts Assessment (SEIA) and Social Life Cycle Analysis (SLCA). The latter, although is in its early steps of development, has been considered to have substantially promising methodological attributes for bioindustries’ social sustainability assessment. Although ongoing research tackles the incorporation of the environmental dimension into extended techno-economic assessments, no integration of the social pillar into such assessments has been made. Given that, this review focuses on the social dimension for integrated sustainability assessments of biobased industries to assess the main social impacts resulting from each operation or from the bioenergy sector. The current review focuses on the importance of social sustainability indicators and evaluation techniques. By discussing the methodologies for evaluating social impacts, a systemic methodology for assessing and integrating the social dimension into the sustainability assessments of bioindustries is developed, considering the four main iterative steps of an SLCA framework and three useful SLCA-based approaches including Product Social Impact Assessment; Prosuite and the UNEP SETAC Guidelines for SLCA of Products. It is concluded that the term systemic analysis implies that the whole approach needs the capacity to understand different subsystems and relations between them. Accordingly, the systemic assessment of biobased technologies should simultaneously include technological, economic, social and environmental dimensions. The result of this study identifies social impacts in the bioeconomy and particularly highlight the importance of considering social issues in biobased industries’ design and innovation. [less ▲]

The paper focuses on the Romanian consumer behavior and perceptions related to meat consumption, following that it is deeply embedded in the Romanian dietary food culture. The meat consumption is an indicator of the population welfare degree and it is often used in assessing the food safety. The novelty lies in the investigation of meat consumption hindering factors, with a special emphasis on those related to the environmental protection. The main research objective was to evaluate the importance attached by consumers to meat products safety in order to develop resilience to environmental pressure through quality food production and consumption. Statistical analysis revealed the interest in meat free-off antibiotics, hormones and no genetically modified. From a pratical perspective, the results indicate directions that policy-making should follow to adapt the production sector to the market demands, along with promoting a more sustainable consumption pattern.

demander dans quelle mesure l’injonction du brigand qui exige « la bourse ou la vie ! » peut être comparée à la norme de comportement édictée par un Etat sous la forme d’une loi, c’est poser la sempiternelle question de la frontière qui sépare le droit du non-droit, tout au moins dans une perspective juspositiviste, en tant que cette école de théorie du droit refuse de définir le phénomène juridique en se référant à une valeur ou un ensemble de valeurs. La frontière du droit et du non-droit est en effet particulièrement difficile à tracer, nonobstant plusieurs siècles de discussions philosophiques à ce sujet. Lorsque, fatigué de parcourir les chemins, le brigand décide de s’installer en ville pour s’y adonner au racket des commerçants du quartier et qu’il s’adjoint ensuite le concours d’autres bandits, c’est un gang de malfaiteurs qui voit le jour. Si, ultérieurement, ce gang se concerte avec d’autres bandes de truands pour s’épauler mutuellement dans les exactions auxquelles ils se livrent sur leurs territoires respectifs, il prend alors la forme d’une organisation criminelle ou, au sens large du terme, d’une « mafia ». Le cinéma de Francis Ford Coppola, Martin Scorsese, Brian De Palma, Sergio Leone ou bien encore Matteo Garrone, entre autres, dépeint, souvent avec réalisme, la genèse et le fonctionnement de telles organisations criminelles. La communication a proposé, au moyen d’illustrations tirées des films de ces grands cinéastes, une analyse de microscopie juridique du crime organisé. Une description serrée de la particule élémentaire du phénomène juridique, identifiée par Lucien François dans son ouvrage de théorie du droit Le cap des Tempêtes sous l’appellation de « jurème », met en lumière une indéniable proximité entre les techniques de pouvoir utilisées respectivement par le brigand isolé, la bande organisée et l’Etat souverain. En remontant ensuite vers la structure plus complexe d’un système étatique, on se demandera si, en fin de compte, dans la vision juspositiviste poussée au bout de sa logique par Lucien François, l’Etat ne pourrait être réduit, d’un point de vue ontologique, à un pouvoir de fait comparable, par les techniques de contrainte qu’il exerce sur ses sujets, à une organisation criminelle – abstraction faite des valeurs promues ou poursuivies par tel ou tel appareil étatique.

Introduction Different methods for in-vivo characterization have resulted in different maps of the human dorsal premotor cortex (PMd): Task-based functional studies suggested a rostro-caudal gradient corresponding to a cognitive-motor gradient1,2 and mapping based on resting-state functional connectivity (RSFC) likewise suggested a subdivision along the rostro-caudal axis3. In contrast, mapping based on structural connectivity as assessed by probabilistic diffusion tractography (PDT) provided evidence that the dorsal part of the precentral gyrus (PG) is organized along a ventro-dorsal axis4. However, there is currently no multimodal mapping of a broadly defined PMd. The present study used a multimodal approach to (1) identify a robust topographical organization of the right PMd by using connectivity-based parcellation (CBP) applied to a meta-analytic approach of task-related coactivation data (i.e. meta-analytic connectivity modeling, MACM5,6), and (2) examine whether the thus obtained parcellation pattern would be reproduced by CBP based on two other connectivity modalities: unconstrained functional (as reflected by RSFC) and structural as measured by PDT based on diffusion-weighted imaging (DWI). Methods A volume of interest (VOI) was defined by merging PMd activation sites from several meta-analyses serving as robust functional localizers of the PMd while excluding primary sensorimotor areas. MACM-CBP6 was performed using Brainmap database. RSFC-CBP and PDT-CBP were performed on distinct datasets to ensure independent parcellation7. RSFC-CBP was computed on RS data of 124 healthy subjects (age: 39.5 ± 11.5 yrs., 66 males) from the 1000BRAINS project8. The voxels’ time series (TS) were first cleaned from confounding effects using PCA denoising and global signal regression. RSFC was then computed by Pearson correlations between the TS of the VOI voxels and those of the rest of the brain. PDT-CBP9 was performed on DWI data of 20 healthy subjects (age: 18.5 ± .76, 10 males) using FSL. Several cluster solutions (k solution) were examined with k-means for MACM- and RSFC-CBP and spectral clustering for PDT-CBP. The choice of the k solution was driven by task-based functional data (MACM) based on three criteria: variation of information, percentage of deviants, and silhouette value6. Results The selected criteria jointly identified the 5-cluster (5k) solution as optimal across the range of functional studies from Brainmap database (Figure 1). Examination of stability across subjects following PDT-CBP further suggested that k=5 may be considered a local optimum within 2 ≤ k ≤ 6. This solution revealed a similar pattern of topographical organization across modalities (Figure 2) with a subdivision along both rostro-caudal and ventro-dorsal axes, including a rostral cluster lying mainly anteriorly to the PG, a central one at the intersection of the precentral sulcus and the superior frontal gyrus, a caudal one in the posterior part of the PG, a ventral one adjacent to ventral PM, and a dorsal one adjacent to the inter-hemispheric premotor areas. Discussion For the first time our study revealed that the PMd could be divided along two axes: rostro-caudal and ventro-dorsal. This is consistent with previous functional2 and microstructure studies10 in humans and non-human primates suggesting a rostro-caudal distinction and with a previous PDT-CBP of the (dorsal) precentral gyrus4 showing that it could be subdivided in the ventro-dorsal direction. Importantly, this topographical organization was found in the independent analysis of three different connectivity aspects: task functional, unconstrained functional and structural, each based on different datasets. In sum, different modalities consistently show that the PMd can be subdivided into 5 subregions organized along both rostro-caudal and ventro-dorsal axes, comprehensively integrating patterns previously revealed by different methods.
