Agricultural accumulation has been one of the main source determined the social differentiation in Vietnamese countryside. The complexities of agrarian changes under the post - socialist industrialization with high rate of agricultural land conversion in recent context reveal the new forms of capital accumulation and social differentiation. This research investigates how land conversion process to industrial zones and clusters affected to the way that different groups of peasant households accumulate their resources. The study was carried out in 3 districts of Hung Yen province from 2006 to 2010. The study results are as follows: first, the land conversion to industrialization has impact on not only the decline of household landholdings but also the changes value of land which are the sources of social conflicts and informal land transfer. Second, in the context of land conversion to industrialization with tiny plots of land, low return from agricultural production and more opportunities of non-farm activities, even when non-farm employment is very profitable, peasant households are not likely to give up their land but maintaining agricultural production for not only their basic and secure livelihood but also for their identity. Third, among the affected peasant groups, the households with non-farm background tend to be in better position in engaging to high - earning activities. They are likely the rich peasants in opposed to the poor group with farming background and lost more than 50% of their agricultural land. This research has showed that the industrialization policies have to deal with the proportion of agricultural land would be transferred for industrialization zones and other measures in order to limit the conflicts as well as the social differentiation in countryside.

The Katangan copper-cobalt deposits (Democratic Republic of Congo) are part of the Central African Copperbelt, one of the world’s greatest metallogenic province. The ore comes to the surface in a series of hills isolated in the miombo woodland. These unique ecosystems present high metals concentration levels where a specific vegetation develops. Flora comprises more than 600 species from which 30 are endemics. Due to the recent revival of mining activities in the region, copper plant communities of Katanga and their associated flora are now critically threatened. Tenke Fungurume Mining sarl (TFM), an important mining company operating in Katanga, has developed a Biological Diversity Action Plan (BDAP) to conserve copper-cobalt flora and mitigate potential species extinction risk. One of the most original BDAP tasks is an ecosystem reconstruction experiment that should preserve plant communities representative of the diversity found on the exploited hill and to provide the plant material for further post-exploitation restoration. From December 2007 to April 2009, full vegetation blocks were translocated with their soil mat on an adequate mineral substrate of 1500m². Since 2008, the artificial ecosystem is monitored every year. Three communities were successfully recreated. A total of 144 species were found in the ecosystem which represents more than 80% of the original species richness. The reconstructed ecosystem seems to favour the most tolerant species to copper. This first experience shows that ecosystem reconstruction is successful and may be used as a strategy to conserve copper-cobalt plant communities in their habitat. [less ▲]

While the influence of the grinding media alloy composition on the flotation performances of sulphide ores has been widely studied, its role in the flotation of mixed (oxide and sulphide) ores is poorly documented. For some deposits, the mixed ores zone is well developed and can be of great importance for the economics of a mining project. These ore types often present technical challenges for their beneficiation such as sulphides tarnishment, slimes generation, presence of hydrophobic gangue or presence of acid consuming gangue. This study highlights the importance of matching the right grinding media alloy to the mineralogy of the ore, particularly its degree of weathering and to the subsequent flotation scheme. Shifting the grinding media towards less electrochemically active alloys significantly enhanced the grade-recovery curves and the flotation kinetics of the sulphides fraction, particularly when high degrees of sulphides oxidation were induced within the orebody or during stockpiling. For ores with high acid consuming gangue and medium acid soluble copper content that require a preconcentration of the oxide fraction by flotation through activation by sulphidisation, the higher sulphides flotation rates achieved with the use of high chromium alloys limited the amount of sulphides entering the sulphidisation stages and led to a better selectivity between acid insoluble and acid soluble copper allowing better downstream extractive metallurgy performances.

Lignocellulosic substrates constitute a promising alternative resource for the sustainable production of energy (biofuels), biobased products and organic compounds. In the past, the extraction and the valorization of cellulose (into fermentescible glucose) constituted the central axis of lignocellulosic biorefinery processes. Degraded hemicelluloses and lignins were however recovered as side-products with no possibilities of high-added value applications. Within the context of an integrated biorefinery, and for economic reasons, the recovery and the non-energetic transformation of lignins have opened recently new horizons. Lignin is a cross-linked phenolic polymer and is considered as a potential alternative to petrochemical polymers or as a source of antioxidants for cosmetics and food industry, resins, chelating agent... As the final application of lignin is dependent of both extraction process and type of lignocellulosic sources, the development of fast and efficient physicochemical characterization methods is thus a prerequisite to optimize extraction processing conditions. In this study, beech wood particles (Fagus sylvatica L.) collected in the region of Gaume (Belgium) were delignified at atmospheric pressure by a mixture of formic acid/acetic acid/water. The effect of cooking time and temperature was evaluated on delignification and on chemical structure of lignins obtained by precipitation from the black liquor after treatments. To study the delignification, a central composite design and response surface methodology were used for the optimization of two treatments parameters, i.e. time (between 1h30 and 4h30) and temperature (from 87 to 107°C). These two variables were optimized for delignification yield, pulp yield, concentration of degradation products (furfural and hydroxymethylfurfural) and for the amount of residual linkages between lignin constitutive units. On the basis of our results, higher delignification yields were obtained when cooking time and temperature increased. However, for high cooking times and temperatures, pulp yield decreased because hemicelluloses and cellulose were hydrolyzed and the production of furfural and hydroxymethylfurfural was augmented. The structural and physico-chemical features of extracted lignins were investigated with different analytical tools, namely infrared spectrometry, thermogravimetric analysis, size-exclusion chromatography, mono-dimensional nuclear magnetic resonance (NMR 1H and NMR 13C) and bidimensional NMR (heteronuclear HSQC experiments). The characterization of lignins indicated the occurrence of a repolymerization phenomenon when both cooking time and temperature increased. Indeed, HSQC NMR spectra presented oxidized syringyl units. Otherwise, thermogravimetric analysis and HSQC analysis showed the presence of hemicelluloses in lignin samples from soft treatments (1h30, 87°C). Some linkages between lignin and hemicelluloses were not cleaved under these experimental conditions. [less ▲]

The present work was carried out in the frame of a Belgian Science Policy project (PONDSCAPE -“Towards a sustainable management of pond diversity at the landscape level”). During the summer 2008, 7103 lymnaeids snails were collected from 125 ponds distributed in 5 clusters of 25 ponds each. Each cluster was located in a different geological region of Belgium. These snails belonged to the following species or genus: 2474 Galba truncatula (the main intermediate host of Fasciola hepatica in Belgium) and 4629 Radix sp. Moreover, several biological (presence of trampling and dungs, snail size …) and non biological factors (pH, depth, fences …) were also registered from the different biotopes. DNA was extracted based on Chelex® technique. Then the snail DNAs were screened through a multiplex PCR that amplifies the lymnaeid internal transcribed spacer 2 sequence (500-600 bp) (acting as an internal control) and a 124 bp Fasciola sp. sequence. Lymnaeid snails were found in 93 biotopes (66%). Thirty Galba truncatula (1.31%) and 7 Radix sp. (0.16%) were found positive for Fasciola sp. A classification and regression tree (CART) analysis was performed in an attempt to better understand the relative importance and relationships among the different recorded factors. For example, the geographic localization is one of the best explanatory variables for the abundance of the different snail species and the presence/absence of faecal material is the best explanatory variable for the presence of specific F. hepatica DNA material in the different screened snails.

Le cours de Médecine Palliative est organisé en avant-dernière année des études médicales de 2e cycle par deux enseignants, Médecin Généraliste et Médecin Hospitalier. Ce cours a été dispensé pendant 10 ans selon un format traditionnel ex cathedra. Il était dispensé par de nombreux intervenants pluridisciplinaires. Une évaluation des enseignements a montré que les étudiants jugeaient les interventions trop théoriques, sans lien avec leurs questions et préoccupations. En conséquence, c’est la discipline « Médecine Palliative et de Soins de Vie » qui ne suscitaient pas d’intérêt. De nouveaux objectifs et de nouvelles modalités pédagogiques ont été introduits en 2010-2011 à l’attention de 100 étudiants. L’objectif principal est le développement chez les étudiants d’une attitude réflexive face à la discipline « Médecine Palliative ». Les outils pédagogiques introduits dans le dispositif sont le portfolio électronique, une vignette clinique évolutive, l’accompagnement à distance de chaque étudiant par un tuteur, des cours en présentiel. La pratique réflexive de chaque étudiant est évaluée au terme du dispositif, conjointement par les 2 enseignants sur base de critères et d’indicateurs. Voici une illustration des critères utilisés : - Intensité des interactions dans le carnet d’apprentissage électronique (et aux cours) - Pertinence des interventions - Engagement dans la tâche - Capacité réflexive (pertinence de l’analyse et de la régulation de la situation décrite dans la vignette) - Qualité de l’auto-évaluation et identification des éléments déclencheurs de progrès - Degré d’apprentissage (Bilan d’atteinte des objectifs fixés par le cours et décrits) La communication orale présentera le dispositif d’évaluation, les critères et les indicateurs utilisés, les premiers résultats de l’évaluation des étudiants, les perspectives de régulation du dispositif d’évaluation.

The detailed study of the nebulae ejected from Luminous Blue Variables and the circumstellar bubbles around Wolf-Rayet stars, which radiate strongly in the IR due to the heating of dust, is crucial for understanding the massive stars evolution. With Herschel, the largest telescope ever flown in space, we are able to study the gas and the dust in these circumstellar environments in the full far-infrared waveband. In the context of 'Mass-loss of Evolved StarS' Herschel guaranteed time key programme, we have obtained imaging and spectroscopic observations of nebulae associated with Luminous Blue Variable and Wolf-Rayet stars using PACS, one of the three instruments onboard Herschel. A description of these observations and first results of the data analysis are presented. [less ▲]

The Bonobo could be one of the species facing the biggest conservation challenge in the years to come. Endemic to the West Democratic Republic of Congo (DRC), its survival depends exclusively on the management measures taken by a country having to deal concomitantly with many problems affecting its development, i.e. demographic explosion, poverty, insecurity and deforestation. But the survival of bonobos, classified as Endangered by IUCN (2010) and restricted to a relatively small range, will require newly designated and effective protected areas. This will imply long-term conservation programs, taking into account the bonobos’ populations requirements, as well as the local socio-economic needs and realities. In 2005, a large population of bonobos has been identified in Western DRC, in a rather eccentric part of the species range compare with the best known populations inhabiting the rainforest of center DRC. The Western region, known as the Lake Tumba Landscape, is characterized by a relatively poor rural human population, an active bushmeat trade, and is divided into several logging concessions and cattle ranches. In 2007, WWF initiated a vast conservation program in the area, including an eco-tourism project involving the habituation of 2 bonobos populations. Until now, only sparse information has been gathered but preliminary studies indicate that habitat use by bonobos – a forest-savannah mosaic – differs substantially from that of other known populations. The objective of the research is to define the eco-ethological profile of those 2 populations. For this purpose, we will characterize diet and food preferences, examine population density and try to identify factors inducing nesting sites’ choice. This information will help understanding habitat use by bonobos in the Western region, and should allow us to come up with specific management measures to be adopted by logging concessions, WWF and ICCN as part of the region’s conservation program.

Explaining a difference in atmospheric CO2 dynamics among interglacials is an elusive issue. Several biogeochemical mechanisms of different origin are involved in interglacial CO2 dynamics leading to a CO2 release from the ocean (carbonate compensation, coral growth) compensated by a land carbon uptake (biomass and soil carbon buildup, peat accumulation). The balance between these fluxes of CO2 is delicate and time-dependent, and it is not possible to provide firm constraints on these fluxes from proxy data. The best framework for quantification of all these mechanisms is an Earth System model that includes all necessary physical and biogeochemical components of the atmosphere, ocean, and land. To perform multi-millennial model integrations through the Holocene and Eemian, we use an intermediate complexity climate model, CLIMBER-2, coupled to the LPJ DGVM model with recently implemented boreal peatland module. The global carbon cycle is never in complete equilibrium during the glacial cycles due to changes in small but persistent fluxes such as terrestrial weathering. This complicates setting up the interglacial runs as the usual approach to start model integration from equilibrium state is not valid anymore. To by-pass this problem of non-equilibrium initial conditions, the model is initialized with the oceanic biogeochemistry state taken from a transient CLIMBER-2 simulation through the last glacial cycle. In this simulation, the CLIMBER-2 model was run through the last glacial cycle with carbon cycle in “offline mode” as interactive components of the physical climate system (atmosphere, ocean, ice sheets) were driven by concentration of greenhouse gases reconstructed from ice cores. In response to simulated climate change, the carbon cycle model was able to reproduce the main features of glacial CO2 dynamics reconstructed from ice cores. Results of the CLIMBER-LPJ model integrations through the Holocene and Eemian interglacials in terms of climate changes and atmospheric CO2 and d13CO2 dynamics will be presented. [less ▲]

The aircraft loading problem is a real-world combinatorial optimisation problem highly constrained. Indeed, loading the aircraft so the gross weight is less than the maximum allowable is not enough. This weight must be distributed to keep the centre of gravity (CG) within specified limits. Balance control refers to the location of the CG. Both lateral and longitudinal balances are important in order to minimize fuel consumption and to satisfy stability and safety requirements. Moreover, an aircraft has usually several cargo compartments with specific contours and structural limitations such as floor loading, combined load limits and cumulative load limitations. The topic of this talk is the description of a mixed integer linear program for the problem of loading a set of Unit Loading Devices (ULDs) and bulk into an aircraft. An ULD can be a container or a pallet and is characterised by the type, contour, weight and height. Experimental results for real data sets show that the model achieves better balanced solutions in only a few seconds compared to the solution obtained by load masters. [less ▲]

Developing predictive models of reservoirs is often complicated by the spatial heterogeneities and the different scales which control flow and transport processes. In numerous studies over the past two decades, geophysical imaging techniques have proved very useful for reservoir characterization. However, the loss of resolution and the non-uniqueness of standard solutions to inverse problems strongly limit the use of such deterministic imaging approaches. On the other hand, the use of common geostatistical approaches for reservoir characterization, for instance from logging information, may be a difficult task, since accurate variogram information is difficult to obtain (dense sampling in the vertical and lateral directions), and also because a high number of conditioned simulations is needed to remove statistical bias. Combining the high spatial sampling of deterministic geophysical imaging methods with geostatistical constraints, valid in the whole image plane, appears as a very promising approach to enhance reservoir characterization. To do so, we use a parameterized model covariance matrix based on standard variogram functions and a prior model as regularization operator in the inversion of electrical resistance data. This way of including additional data is not restricted to electrical data but the variogram parameters may be also inferred from for example available textural or lithological information. The benefit of the presented approach is twofold: (i) It honors the spatial statistics of the reservoir and (ii) it alters the posterior model by further reducing model ambiguity inherent to the inversion compared to classical (smooth model) regularization. The proof of concept is given by synthetic studies carried out on random fields from Gauss simulations with varying (an)isotropic scale lengths using different model (co)variogram functions. We also demonstrate the approach on electrical field data combined with borehole electromagnetic data from two artificial sea inlets in the nature reserve "The Westhoek" near the French-Belgian border. The electromagnetic logs were used to calculate an experimental vertical variogram characteristic of the study site. The results enabled to determine the extension of the salt water plume laterally, and significantly enhance its extension in depth, but also in terms of total dissolved solid content. These observations are in agreement with the hydrogeological situation at the site. A comparison with borehole data shows that the results are much more plausible than results obtained with a traditional smoothness constraint used as regularization operator. In conclusion, the incorporation of geostatistical information, vertical variograms in our case, in the inverse process improves imaging capabilities for reservoir characterization significantly.

Les capitulaires royaux et impériaux carolingiens des VIIIe et IXe siècles regorgent d’injonctions faites aux évêques et aux prêtres de veiller à la formation religieuse du peuple franc. De nombreuses précisions y sont apportées relatives tant à la matière à enseigner qu’aux moyens autorisés par le ou les souverain(s) pour contraindre hommes, femmes et enfants de toutes conditions à s’instruire. A leur lecture, il devient évident que Charlemagne et ses successeurs se sentaient personnellement responsables du salut de leur peuple et qu’ils restèrent en permanence soucieux de mener à bien cette mission. Cette communciation revient sur ces injonctions et propose quelques réflexions sur la conviction qu’avaient les souverains carolingiens d’être responsables de la formation religieuse du peuple. L'auteur considère les moyens – pédagogiques et coercitifs, menaces spirituelles et pénales – mis en œuvre, d’abord dans l’empire de Charlemagne et de Louis les pieux, puis dans les royaumes issus du traité de Verdun, pour faire adhérer le peuple à la foi chrétienne, en attachant une attention toute particulière aux motivations politiques et idéologiques des souverains.

Considérant que la représentation télévisuelle d’un match de football peut être pensée comme le produit d’un dispositif défini par un ensemble de codes « classiques », nous interrogeons quelques oeuvres issues du champ de l’art contemporain (Deep Play de Harun Farocki, Heisenbergs Offside de Jules Spinatsch, Zidane : A 21st Century Portrait de Douglas Gordon et Philippe Parreno, etc.) qui s’emparent de ce spectacle télévisuel pour s’affranchir de ses codes. Dans le passage de ce spectacle à l’univers de l’art contemporain, c’est le dépassement de l’écran unique, du carcan narratif de la durée de jeu, de la subordination du découpage à la circulation du ballon, et du tout pouvoir de l’image analogique et donc « réaliste » qui est en jeu. Notre analyse de "Deep Play" (H. Farocki) tout particulièrement démontre qu’en vertu de son passage à l’espace muséal – qui déplace mais conserve aussi dans une certaine mesure l’aspect ludique de l’objet originel – le spectacle du football se voit doté d’une nouvelle dynamique narrative proche de celle de la mosaïque. Ce modèle mosaïque, contenu implicitement (mais bridé aussi) dans le spectacle à acteurs multiples et sur grande surface, autorise alors une nouvelle appréhension de ce spectacle comme objet fragmenté.

The conference has been centred on an approach of conditions that make each and every child really feel welcome in ECEC services. Following the European childcare network activities in the nineties, the French Community Government (Belgium) has decided to issue the Quality and Care Code : every person who takes care of a child aged 0 to 12 has to elaborate and implement an educational project called in French “projet d’accueil”. This project has to follow the objectives defined by the Quality and Care Code. There is an essential challenge, on various levels of course, but more specifically in terms of development of ECEC services quality : services should be accessible to every child and his family. A short stop on what is meant by “quality of ECEC services” has been proposed. [less ▲]

Le projet RAP est mis en œuvre selon un processus multi-acteurs (PMA). La PMA constitue un cadre de concertation de plusieurs acteurs : producteurs, transformateurs, commerçants, pisciculteurs, éleveurs, structures d’appui, Partenaires Techniques et financiers, etc. Les intérêts de ces acteurs sont très souvent divergents. Mais, ces acteurs sont appelés à apprendre, agir, et innover ensemble dans une approche systémique pour une utilisation optimale et une gestion durable des ressources naturelles de ces bas-fonds. Après deux années de mise en œuvre de cette approche, nous évaluions le niveau d’appropriation par les acteurs. Les conditions de mobilisation des ressources humaines et financières pour la concrétisation de cette innovation ont été évaluées de même que les actions qui ont été mises en œuvre dans le processus d’ancrage de ce partenariat. Les acquis, les faiblesses et les contraintes à l’appropriation ont fait l’objet d’une analyse critique. En somme, les PMA sont en construction et il existe de réelles motivations autour de cette approche. [less ▲]

Ce travail se propose d’analyser les phénomènes du séchage convectif d’un milieu poreux non saturé. Le modèle de calcul considère le couplage des équations de la couche limite et celles qui décrivent le transfert de chaleur et de masse dans un milieu poreux, ayant les caractéristiques du béton renforcé avec des coupeaux de bois. La simulation effectuée montre l’effet de certains paramètres pertinents du matériau comme la température initiale et l’humidité initiale, sur le processus du séchage. [less ▲]
