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.

Les pigments préhistoriques sont formés à partir de composés naturels tels les d’oxydes de fer ou les oxydes de manganèse. Ils ont été collectés par les hommes préhistoriques dans leur environnement proche ou parfois à de grandes distances. Connaître leur provenance géographique, ou à défaut établir des relations entre matière première retrouvée en fouille et objets archéologiques décorés, pourraient permettre de retracer la mobilité des populations et d’appréhender les choix techniques opérés ou la mise en place des décors.Ces relations et provenances peuvent être établies à partir de la composition chimique des matériaux employés. Il a été notamment démontré, que pour les obsidiennes ou les minéraux précieux tels les grenats ou les rubis, la nature et la concentration des éléments traces sont caractéristiques des milieux géologiques dans lesquels ils ont été formés. Dans le cadre de Madapca, la même démarche a été appliquée aux pigments préhistoriques. Elle s’appuie principalement sur la méthode d’analyse non destructive PIXE (Particule Induced X-ray Emission) et a été développée pour des pigments provenant des sites d’Arcy sur Cure (Châtelperronien, 32 000 BP) et de l’Abri Pataud (niveau Proto-Magdalénien, 22 000 BP). L’analyse élémentaire des éléments majeurs, mineurs et traces a permis de mettre en évidence des groupes de pigments de composition distincte au sein des niveaux archéologiques étudiés, et donc l’utilisation de sources de matière premières différentes. Dans le cas de l’Abri Pataud (Dordogne), il a été possible d’établir des correspondances entre la composition chimique des blocs de matière première composés d’oxydes de fer et celle des décors peints sur des éléments mobiliers ou sur les écailles ornées provenant de l’effondrement du plafond de l’abri. Dans le cas d’Arcy-sur-Cure (Yonne), nous avons pu montrer que la teneur en éléments traces variaient en fonction de la provenance des blocs de pigments rouges et noirs, trouvés en nombre dans la grotte du Renne. Cette étude démontre l’intérêt des techniques de spectrométrie X pour la différentiation des matériaux colorants utilisés en contexte préhistorique. [less ▲]

Stainless steel is widely used in the daily life in building and food industries as well as in the medical field. However, at long term, bacteria succeed in adhering, proliferating and forming a resistant biofilm on stainless steel. Therefore, surface modification is needed providing metal surface with antibacterial, anti-adhesion and easy cleaning properties. Several biomolecules (antimicrobial peptides, antiadhesion biomolecules and anti-biofilm enzymes) were immobilized on stainless steel thanks to different immobilization techniques. In a first approach, cationic peptides have been embedded in a LBL architecture comprising anti-adhesion biomolecules. In a second approach, small inorganic-binding peptides isolated by phage display technology and recognizing specifically the steel surface were used as linker for antimicrobial peptide immobilization. Finally, antibacterial peptides were covalently grafted onto an organic-polymeric interlayer deposited by plasma. Resulting antibacterial, antiadhesion and anti-biofilm properties were characterized and the advantages of each immobilization technique were documented. The biocidal effect of these surfaces was demonstrated against Gram+/- bacteria. Coated stainless steel surfaces led to 95% reduction of S. epidermidis adhesion vs bare substrate. By combining both antibacterial and anti-adhesion biomolecules, we produced stainless steel surfaces with better cleanability. A biofilm-releasing glycoside hydrolase was also immobilized on the surface and showed to confer anti-biofilm properties to stainless steel. Moreover, we provide valuable insight about the resistance of the coating to close to real life cleaning conditions. [less ▲]

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.

Background The immune system controls, at least partially, human papillomavirus (HPV) infection and subsequent tumor development as demonstrated by a higher tumor prevalence in immunodeficient patients. Around 90% of HPV-infected women will clear the virus within two years. However, it remains unclear which immune cells are implicated in this process and no study has been performed evaluating the direct interaction between HPV and Natural Killer (NK) cells although these cells play a key role in host resistance to virus and tumor. Methods/Results By immunochemistry, we demonstrated an NK cell infiltration in HPV+ squamous pre-neoplasic lesions. Since HPV cannot grow in vitro, virus-like particles (VLP) were used as a model for studying the NK cell response against the virus. Interestingly, NK cells displayed a higher cytotoxic activity (CD107 and chromium release assays) and cytokine production (TNF-α and IFN-γ) in the presence of HPV-VLP. Uptake of HPV-VLP by dendritic cells (DC) has been shown to induce their activation, therefore, we investigated by flow cytometry and microscopy whether the stimulation of NK cell activity is linked to VLP internalization. We observed a faster entry into these cells compared to DC. Furthermore, virus uptake by NK cells is mediated by macropinocytosis, whereas this entry is dependent on clathrin or caveolin endocytosis pathways in DC. Using NK cell lines expressing or not CD16 and blocking antibody, we demonstrated that CD16 is necessary for HPV-VLP internalization, but also for degranulation and cytokine production. Conclusion Thus, we show for the first time that NK cells interact with HPV and could participate in the immune response against HPV-induced tumors. [less ▲]

Global food crisis has played its negative effects on sustainable development. A question has been raised: how could the families in both rural and urban areas struggle against this present global food crisis? This research aims at documenting household food consumption from January to October 2010 by interviewing with and operating a record keeping system of food consumption in 250 households of various income levels living in two different areas of Hanoi, the inner and suburban districts. There is variety of animal products consumed in each family of both areas. Indeed, pork meat, broiler chickens and freshwater fish were popularly used in all families; and broiler ducks are usually consumed in summer season. Furthermore, in the inner districts, there is a rise in the demand of red meats and aquatic products, particularly beef and seafood products. Home-made foods are still a major source of foods for all family members of most of families, however, families in urban areas tends to have breakfasts and lunches in restaurants. In rural areas, the soya curd (tofu) and self-made products from broiler chickens, vegetables, and the rice play an important role, occupying from 15% to 30% of food expenditures. In addition, pork meat and freshwater fish are usually bought in village markets. Through incomes of 82% of households are mainly from agricultural production or from between agriculture and off-farm activities, thanks to self-made products in most of households, the rural areas are not considerably influent by the present global food and financial crisis. Nevertheless, in order to achieve sustainable development, it is necessary to equip farmers with sufficient knowledge of practical agricultural production. [less ▲]

In previous studies, conflicting results could be found regarding the impact of weather forecasts on travel decisions, e.g. Khattak and De Palma (1997) found no significant effect of acquiring forecasted weather information on the probability of adapting mode and departure time, whereas the results reported by Hagens (2005), Niina (2009) and Kilpelainen and Summala (2007) indicated that weather forecast do play an important role. Therefore this paper investigates the changes in activity-travel behavior in response to weather forecasts. The data for this study is collected by means of a stated adaptation survey, which is both administered on the internet and via a traditional paper and pencil questionnaire. In total, 595 respondents completed the survey. To obtain an optimal correspondence between the true population and the sample weights are assigned to the observation. Results indicate that weather information plays a dual role. On the one hand people do alter their activity-travel behavior in response to weather information, albeit these changes are not as pronounced when compared to actual weather. On the other hand the extent (frequency and media type) to which people are exposed to these weather forecasts appears to play only a marginal role. This dual role weather information plays in this study appears to be supported by the conflicting international literature and therefore revealing the underlying psychological motivations to change one's activity-travel behavior is a key challenge for further research.

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 objective of this presentation is to carry out thermal model reduction in the context of the finite element method. The finite element model is decomposed in several sets of adjacent faces called super-faces. Specialized algorithms such as the METIS partitioning algorithm are used to automatically generate the super-faces. Several constraints may be imposed, e.g., the size of the super-face, its aspect ratio or its aperture angle. Once the model is decomposed, view factors between super-faces are calculated with direct numerical integration or ray-tracing methods. This method offers a very substantial reduction of the computational burden compared to the full model, which is particularly interesting for pre-design studies or specific applications such as deployable structures.

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 ▲]

Predictive microbiology is considered by the European legislation as a tool to control food safety. Meat and meat products are particularly sensitive to contamination with pathogens. However, development of predictive microbiology models and interpretation of results require specific knowledge. A free web based model has been developed for an easy use by people who are not experts in this field as industries and public authorities. The model can simulate the growth of Salmonella spp, Listeria monocytogenes and Escherichia coli O157 in minced pork meat and on pork meat product (white pudding) under different environmental conditions. The model provides simulations under static or dynamic conditions over time. The user also has the opportunity to import the specific growth rate and cardinal parameters of a bacterium. Unlike polynomial models currently available, this free web access model is distinguished by the use of secondary square roots and primary logistic model with delay. This model permits to have a real time process management, to prospect new formulation for safer products or to design safer processes, to estimate the shelf life of a food product, etc [less ▲]

In the context of climate change, the Greenland Ice Sheet (GrIS) plays an important role in sea level variation and oceanic thermohaline circulation changes. Unfortunately, Global Climate Models do not illustrate enough the characteristics of Greenland. To solve that, specific RCMs have been developed to take into account the features of polar regions. In this project, we compare three RCMs : the MAR model, the RACMO model and the Weather Research and Forecasting (WRF) model. WRF is an open source model developed by the Mesoscale and Microscale Meteorology Division of NCAR. We use here the standard WRF (version 3.2.1) and its polar optimization (called polar WRF). The MAR version tuned for the GrIS and coupled with a 1D surface scheme called SISVAT (for Soil Ice Snow Vegetation Atmosphere Transfer) is compared here. The version of RACMO is a specific version for the Greenland climate, RACMO2/GR. This model contains a special surface module for snow-ice treatment and other modifications concerning, for example, the surface turbulence heat flux or the surface roughness. The comparison is made on a domain centered on Greenland at a 25-km horizontal resolution over the 1995-2005 period when Automatic Weather Station (AWS) measurements are available from the Greenland Climate NETwork (GC-NET). Statistics (mean, bias, RMSE, correlation coefficient) are calculated for the near-surface temperature, surface pressure, 10m-wind speed and specific humidity for winter (October to April) and summer (May to September). In addition, the modeled snowfall are evaluated with ice core-based snow accumulation climatologies. Comparison shows a significant improvement from RCMs compared to the reanalyses (NCEP2 and ERA-INTERIM) in respect to the AWS measurements. RACMO and MAR seem to compare better with observations than WRF. [less ▲]

Vietnam locates in the most active region (Asia), where gains the highest economic growth rate and highest milk consumption in the world. Milk growth rate is higher than almost other agricultural products in the past 10 years in this region (Nancy, 2008). Vietnam is also one of the highest milk productivity in the Asia. Milk consumption in Vietnam is increasing rapidly (Nancy, 2008). However, the dairy industry in Vietnam is currently able to meet only 22 percent of domestic demand; the remaining amount has been imported from overseas suppliers and producers (VOV News/VNA, 2008). In addition, the linkages among the actors and stakeholders in the value chain of milk in the North of Vietnam are very weak. It leads to low effective in the production of the whole chain. This paper based on semistructure, standard questionnaires and PRA method to collect data of dairy farms in Sonla province, of milk collecting centres, of dairy plan and of milk distributors in 2008-2010. The findings show that dairy plan is the most powerful actor in the chain and it drives the whole chain. The value added of the chain is distributed unequally among determinants in the bias orientation to the non-farmer (non-producer). Opportunity cost of land, capital, and family labor in farm does not include when they calculate their benefits, thus it is not reflect the real situation and their value added would be much lowers. Weak linkages among participants in the chain with stakeholders and insufficient supports discourage farmers to develop their production. [less ▲]

The direct gap semiconductor germanium tin (GeSn) is an attractive material for next-generation devices in nanoelectronics as well as in photovoltaic applications. However, its detailed electronic properties have not yet been clearly understood. Recently, admittance spectroscopy has become a popular analytical tool in materials research and development because it involves a relatively simple electrical measurement whose results may establish accurate characteristics of materials. The aim of this work is to study the effects of the annealing temperature on the electrical nature (rectifying or non-rectifying) of the metal contact by admittance spectroscopy. A numerical method, which is based on the solution of the basic semiconductor equations, is applied to simulate the material structure. From the calculation of microscopic quantities such as the modulated carrier concentrations and current densites, we can compute the theoretical admittance and impedance curves as function of frequency and external parameters (temperature and steady-state voltage) and then extract information on the electrical properties of the heterostructure. By a detailed investigation of the impact of microscopic parameters such as the dopant concentrations and the metal barrier height on the electrical characteristics, our objective is to understand the mechanisms of charge transport between the two electrodes.

Poultry production plays an important role in the structure of familial incomes in Vietnam but this activity is currently met with difficulties caused by the great influence of inputs/outputs on the markets and the risks of epidemic diseases. This research was conducted for interviews and records according to book keeping among 280 poultry smallholders; 100 intermediary agents of poultry meat supply chains at the various scales of poultry supply chains and the diversification of poultry markets (poultry producers, private hatcheries, collectors of live poultry, slaughter houses and distributors of poultry meat) in Hanoi Suburb between 2009 and 2010. This research aimed at addressing to improving the income of small poultry producers and identifying the intermediary economic agents and its economic distributions. Furthermore, this research would like to solve restoring the poultry production and the various restraints faced of food contamination in poultry meat supply chains. Institutional organization and financial analysis approaches in different agents was used to calculate the value-added and to explain this problem in poultry meat commodity chains. Institutional organization of poultry meat supply chains is really complex with diverse economic agents. There are not many poultry meat products have a good traceability. These recent years, broiler industrial chickens and ducks met with some difficulties with the profits were very unstable or loss-making. But this industrial broiler chicken still occupies more and more an important role for the demand of domestic consumers. In addition, color broiler chickens were chosen for more satisfying the Vietnamese taste. In fact, local or color crossbred broiler chickens have a good economic performance but the output is still instable. Traders of live poultry and manual slaughter-house have a good economic performance caused by using the source of familial labor and selling directly to consumers. The systems of automatic skill of live poultry have still limited. The consumers do not be informed the useful information on food safety standards. [less ▲]

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.
