Un référentiel a été développé en Wallonie, à la demande du Ministre de l’Environnement, de l’Aménagement du Territoire et de la Mobilité, pour opérationnaliser le concept de « quartier durable » en objectivant les critères minimum à respecter pour inscrire un quartier dans une vision transversale de développement durable. Ce référentiel constitue un cadre général qui régira les projets de quartiers durables menés en Wallonie (Belgique). Les 5 thématiques et les 25 critères qui constituent ce référentiel sont présentés. La grille de critères est ensuite appliquée à douze quartiers de façon à identifier les invariants communs aux processus de conception de ces quartiers et les freins à l’intégration des principes transversaux du développement durable dans les opérations de ce type. Si les critères relatifs aux performances énergétiques des bâtiments ont percolé dans un grand nombre de cas, la mixité des logements et leur accessibilité, la mixité sociale et la participation restent peu abordés. Le référentiel est disponible depuis début 2014 pour tous les acteurs de l’architecture et de l’urbanisme. [less ▲]

This chapter suggests that the notion of ‘social enterprise’ is useful to capture the DNA of organizations focused on fair trade and to locate them within a broader organizational taxonomy. Without seeking to impose a new term that may not resonate for certain actors or regions, this chapter aims to bring two contributions to fair trade research and practice. First, it is suggested that the social enterprise approach is particularly useful as an analytical tool enabling researchers and other stakeholders to capture the evolution and diversification of organizational models in fair trade. Second, the use of a broader organizational approach that is not specific to the sole fair trade sector allows for connections with similar organizations in other sectors and brings a shift from considering mainly what the organizations do (fair trade in this case) towards also addressing what they are (innovative social enterprise models combining market dynamics with social purpose). This chapter is structured as follows. First, the concept of social enterprise is introduced and discussed. Then, the evolution of the organizational landscape of fair trade (in the North) is summarized. Finally, fair trade organizations are examined in the light of the social enterprise concept, with illustrations from a study in four European countries (Huybrechts 2010a; 2012). [less ▲]

The chemical characteristics of co-products recovered during a laboratory-scale wet milling procedure as well as that of whole corn flour were characterised and their digestibility and fermentability value determined using a 2 steps in vitro digestibility and fermentation model of the pig digestive tract. Five co-products differing in their chemical composition were collected and analysed. These co-products differed in their in vitro dry matter Digestibility and in their kinetic of fermentation. High coefficients of digestibility were observed for starchy samples, while low coefficients of digestibility were observed for samples rich in lignocellulosic components. Fermentation patterns of samples analysed were different as well as the profile of volatile fatty acids produced during the fermentation. The production of straight-chain fatty acids produced was significantly correlated with the proportion of starch in the sample, while branched-chain fatty acids were correlated to proteins concentration of samples.

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.

Various cases of human beings ‘dedicated’ to deities are attested in Greek epigraphic evidence. Are these kinds of offerings comparable to the dedication of inanimate objects? Besides, does the fact that someone is said to be ‘sacred’ to a specific deity necessarily involve that he went through a process of dedication? This article aims at providing a global picture of different situations in which processes of dedications took place. Among the several issues that are tackled, the cornerstone of this article consists of two questions: for what purposes did some people decide to consecrate a human being to a deity and what were the consequences for the consecrated individuals on religious and social levels? Different categories of persons will be contrasted, in terms of processes through which they acquire their new status but also in terms of the freedom/lack of freedom which is conveyed by this new status. It will also be shown that, as far as method is concerned, it is necessary to complete a lexical analysis with a contextual perspective for a deeper understanding of the problem. [less ▲]

The growing demand for renewable energy leads to an increase in the development of geothermal energy projects and heat has become a common tracer in hydrology and hydrogeology. Designing geothermal systems requires a multidisciplinary approach including geological and hydrogeological aspects. In this context, electrical resistivity tomography (ERT) can bring relevant, qualitative and quantitative information on the temperature distribution in operating shallow geothermal systems or during heat tracing experiments. We followed a heat tracing experiment in an alluvial aquifer using cross-borehole time-lapse ERT. Heated water was injected in a well while water of the aquifer was extracted at another well. An ERT section was set up across the main flow direction. The results of ERT were transformed into temperature using calibrated petrophysical relationships. These ERT-derived temperatures were then compared to direct temperature measurements in control piezometers collected with distributed temperature sensing (DTS) and groundwater temperature loggers. Spatially, it enabled to map the horizontal and vertical extent of the heated water plume, as well as the zones where maximum temperatures occurred. Quantitatively, the temperatures and breakthrough curves estimated from ERT were in good agreement with the ones observed directly during the rise and maximum of the curve. An overestimation, likely related to 3D effects, was observed for the tail of the heat breakthrough curve. The error made on temperature can be estimated to be between 10 to 20 %, which is a fair value for indirect measurements. From our data, we estimated a quantification threshold for temperature variation of 1.2°C. These results suggest that ERT should be considered when designing heat tracing experiments or geothermal systems. It could help also to assess the geometrical complexity of the concerned reservoirs. It also appears that ERT could be a useful tool to monitor and control geothermal systems once they are in operation. [less ▲]

The spatial analysis of the soil compaction risk has been developed at the regional level and applied to Wallonia (Belgium). The methodology is based on the estimation of the probability of exceeding the preconsolidation stress due to the application of loads on the soil. Preconsolidation stresses (Pc) are computed from the pedotransfer functions of Horn and Fleige (2003) at pF 1.8 and 2.5 and classified into 6 categories ranging from very low Pc (< 30 kPa) to extremely high Pc (> 150 kPa). The computation requires the knowledge of pedological (texture, organic content), mechanical (bulk density, cohesion, internal friction angle), and hydraulic variables (water content available, non-available water content, air capacity, saturated hydraulic conductivity). These variables are obtained from databases like HYPRES or AARDEWERK or from pedotransfer functions. The computation of Pc takes into account the spatial structure of the data: in some cases, data are abundant (e.g. texture data) and spatial variability is taken into account through geostatistical methods. In other cases, the data is sparse but uncertainty information can be extracted from the knowledge of the statistical distribution. Maps of the most probable Pc class are produced. Uncertainty is computed as the classification error probability. Implementation of these methods in Wallonia showed that Pc values higher than 120 kPa are reached either on 64 % of the territory at pF 2.5 or on 55 % at pF 1.8. A higher uncertainty was found at pF 2.5 than at pF 1.8. Uncertainty was also found higher for clay and clayed loess than for other textural classes present in Wallonia. The risk of compaction is defined as the probability that Pc is exceeded by the stress created by a load applied to the soil at a depth of 40 cm, the loads being similar to those induced by agricultural or forestry tires. It appeared that subsoil compaction risks exist mainly in loamy forest soils with small coarse fragments supporting loads similar to that existing on logging machines. In the zones where the uncertainty is low, the developed tool could be used as a basis for providing policy measures in order to promote soil-friendly farming and forest practices. [less ▲]

Ball bearings of turbopumps of rocket engines work in very singular conditions; they are flooded into liquid oxygen or liquid hydrogen. Therefore, the use of any conventional lubricants (oil or grease) is prescribed. Although cryogenic fluids can cool this kind of ball bearing, they cannot separate the surfaces in contact. As a result, there is a significant increase in frictional power losses. This paper presents tests performed on a cryotechnic ball bearing flooded in liquid oxygen. The test results showed that beyond a critical loading of the bearing, a sudden increase in temperature occurred. A thermal model is also put forward, in order to understand and anticipate especially the thermal instability described above. [less ▲]
