Au début des années 70, le Congo Kinshasa est touché par un mouvement de réveil (pentecôtiste) sans précédent. Trois décennies plus tard, c’est un paysage religieux pluriel et très contrasté, pour ne pas dire concurrentiel, qui se donne à voir. Néanmoins, la frontière entre « monde chrétien » et « monde païen » que matérialise un système d’interdits fort, constitue un invariant fédérateur et significatif de l’impératif marquant ce christianisme de conversion. Et pourtant le rappel à l’ordre récurrent, parfois la plainte, des pasteurs à l’endroit des fidèles qui passent « d’une Eglise à l’autre » rend intelligible la perméabilité de cette frontière. Ce que nous mettrons en perspectives en appréhendant ces mobilités sous l’angle d’espaces interstitiels constitutifs de ces mondes religieux. [less ▲]

The measurements of the linear polarisation of visible light from quasars give strong evidence for large-scale coherent orientations of their polarisation vectors in some regions of the sky. We show that these observations can be explained by the mixing of the photons with very light pseudoscalar (axion-like) particles in extragalactic magnetic fields during their propagation. We present a new treatment in terms of wave packets and discuss the circular polarisation. [less ▲]

From the analysis of measurements of the linear polarisation of visible light coming from quasars, the existence of large-scale coherent orientations of quasar polarisation vectors in some regions of the sky has been reported. Here, we show that this can be explained by the mixing of the incoming photons with nearly massless pseudoscalar (axion-like) particles in extragalactic magnetic fields.

In context of the development of the genetic evaluation system of Piétrain boars for crossbred performances, a genetic evaluation model was developed for the estimation of genetic merit of boars for backfat thickness (BF) and meat percentage (%meat). The model developed was a random regression model using linear splines on age which knots at 175, 200 and 250 days. Variance components were estimated by restricted maximum likelihood and Gibbs sampling. Estimated heritability from 150 to 300 days increased from 0.56 to 0.75 for BF and from 0.55 to 0.69 for %meat. Genetic correlation between BF and %meat varied between -0.90 and -0.93 from 150 to 300 days. According to the study of residuals, the developed model was considered to fit well the data especially between 175 and 250 days of age. [less ▲]

Au delà de ses implications techniques, l'informatisation de l'analyse de texte soulève des questions de méthode. Après un recensement des motivations à recourir à des logiciels pour assister l'analyse de données textuelles, nous proposons une typologie distinguant cinq fonctionnalités proposées par ces outils : la lexicométrie, les concordances, les automates, les outils réflexifs et les dictionnaires. Chacune de ces fonctionnalités éclaire les textes d'une manière originale (et partielle). Rapportée à ses usages attestés, chacune de ces potentialités articule des présupposés épistémologiques spécifiques. En définitive, le choix d'un logiciel caractérise autant une démarche de recherche que l'inscription dans un paradigme. [less ▲]

Since the first works on thixoforming, lot of studies have been performed all over the world and the behaviour of the globular semi-solid slurry is now quite well understood. This knowledge had lead to an industrialisation of the technology for low melting point alloys as aluminium or magnesium. For high melting point alloys as steel, this industrialisation is still a wish but seems closer each year. In the aim of this development of the process, it is important to be able to accurately represent the behaviour of the slurry during thixoforming. In this goal, lot of constitutive models has been proposed during the last years. However, until now there isn’t any study about the friction in the case of thixoforming. This knowledge is needed as friction has an important effect on the flow of the slurry during the shaping. The aim of this work is so to propose a quantification of the friction coefficients for the thixoforming technology thanks to experiments on a dedicated tool and comparison with simulations run on the finite elements code Forge2008©. The friction law is a Coulomb limited Tresca one. [less ▲]

We address the anti-windup augmentation problem for plants with saturations on the magnitude, rate and curvature of the control input. To this aim, given an unconstrained closed-loop, we generate a slightly modified strictly proper controller for which the derivatives of the control signal are available and we solve the anti-windup problem for this modified control scheme (namely, an almost anti-windup for the original closed-loop). Based on this “almost” approach, we revisit an existing Model Recovery anti-windup solution for rate and magnitude saturated plants and then we extend the results to the case of rate, magnitude and curvature saturation, by providing a Model Recovery solution to this additional problem. An example illustrates the peculiarities and the effectiveness of the proposed solutions. [less ▲]

La vie en société de milliers d’individus apparentés dans un milieu confiné augmente le risque de transmission des pathogènes. Par le biais de comportements hygiéniques collectifs tels quel le rejet des déchets, les insectes sociaux ont développé des défenses spécifiques contre les pathogènes. Nous avons comparé la dynamique de rejet de différents types de déchets (cadavres, proies et morceaux de vermiculite) introduits dans des nids de Myrmica rubra. L’analyse vidéo, réalisée grâce à un programme original de suivi du déchet et de digitalisation des zones de couvain, a permis un suivi précis du déplacement de ces déchets au sein du nid. La vermiculite a été rapidement rejetée après 12 ± 4 minutes, les cadavres ont été éliminés après 139 ± 28 min et les proies ont été consommées puis rejetées après 17,3 ± 0,3 heures. L’analyse spatiale des déchets a montré un déplacement rapide des cadavres loin du couvain alors que les proies étaient fréquemment apportées près des larves pour la consommation. L’efficacité de la gestion des déchets a été testée par ailleurs en comparant la survie de colonies de fourmis ayant ou non la possibilité de rejeter leurs cadavres. La mortalité des adultes et des larves vivant dans des nids contraints de garder leurs cadavres est significativement supérieure à celle observée dans les colonies contrôles, confirmant l’importance de ce rejet pour la survie et le bon état sanitaire de la fourmilière.

In the first part of this presentation it will be shown how the general linear model is used to describe experimental functional magnetic resonance imaging (fMRI) data from one subject. Functional magnetic resonance imaging is a neuroimaging method which is used to study the human brain and its functional areas. Based on the general linear model, optimal designs for one-subject fMRI experiments can be obtained by application of the D- and A-optimality criterion. Because of the huge design space for fMRI experiments, a genetic algorithm (GA) is employed to find optimal designs for fMRI experiments based on a multi-objective design criterion. The second part of the presentation will focus on the application of mixed effects models in analysis of fMRI experiments from multiple subjects. Optimal designs for multi-subject experiments are considered and the optimal combination of number of subjects and fMRI scanner time/imaging time per subject will be studied with respect to a linear cost function.

For a class of homogeneous hybrid systems we present a set of annular Lyapunov-like conditions for inferring global pre-asymptotic stability of systems. Then, we prove that such conditions are mild, namely, that each globally pre-asymptotically stable system must satisfy them. Based on these results, we design a sum of squares algorithm that constructs a suitable Lyapunov-like function to fulfill such annular conditions. Finally, based on recent results on homogeneous approximations of hybrid systems, we point out that such conditions can also be used to deduce local pre-asymptotic stability for a wider class of hybrid systems.

Living in society in a restricted and confined nest implies important organisational issues. Ants have to control food supply for the whole colony as well as nest defence but they also have to manage everyday life tasks such as waste rejection. Within the nest, ants are faced with different items that have to be used or rejected regarding colony needs. We study whether they can discriminate between three types of items (building material, nestmate cadaver or prey) and accordingly adapt the spatio-temporal distribution of these items. Therefore, we used colonies of the ant Myrmica rubra settled in a 2-dimensional space and introduced different items in the nest centre. We show that each item triggers a specific cascade of behaviour. We observed important differences in rejection time: building items were removed within a few minutes and cadavers after a few hours while preys could be kept in the nest for a day or more. Furthermore, the movement of items by ants leads to specific spatio-temporal patterns. Building items were removed with a straight trajectory from the centre to the exit of the nest. Ant cadavers that could bear pathogens showed a trajectory avoiding and moving away from larvae that are potentially more sensitive to diseases. The moving of preys headed an oscillating pattern: these items were alternatively taken on larvae for consumption and then moved away from them, until final rejection. This specific pattern may be due to the coupled effects of groups of ants acting alternatively to feed larvae and reject waste. In the case of cadavers and building items, only undertaking ants may be active. These results suggest that each ant is able to discriminate and interact with each other leading at the collective level to a complex cascade of behaviour. [less ▲]

Sociality increases risks of disease transmission as genetically related individuals live in a confined environment. Therefore, social insects developed specific defences against pathogens by showing hygienic behaviours such as the rejection of cadavers and other wastes. We investigated if the undertaking and waste management is actually an efficient way of increasing ants’ survival and of limiting pathogens transmission. First, we observed the survival curve of ant colonies that were prevented from rejecting their dead nestmates outside the nest. Colonies that were forced to keep their dead inside the nest showed increased mortality of both adults and larvae in comparison to control nests, confirming that undertaking is an effective way for improving colony’s survival. Then, we compared the rejection dynamics of single waste items (ant cadavers, preys and clay pellet) introduced into ant nests. Clay pellets were quickly rejected within 12 ± 4 minutes, cadavers were dumped outside after 139 ± 28 min and preys were eaten and rejected only after 17.3 ± 0.3 hours. Spatial localisation inside the nest also differs between different items, as most cadavers stayed far from ants’ aggregate and larvae while preys were long-eaten close to larvae and inside ants’ aggregate. These results show that cadavers and preys are managed differently before becoming contagious, thus preventing effectively pathogens transmission inside the nest. [less ▲]

Hanoi province, Vietnam has much potential for agricultural development with its large consumer market for agricultural products, soil and water resources, natural climate, physical and social infrastructure. It is also one of provinces that has attracted a large number of investors. However, there are few agriculture investment projects in Hanoi in recent years. This paper presents the results of the structure interview of 200 managers of agricultural firms, co-operatives and farms in Hanoi province in 2008-2009. Even if these enterprises are pleased with their business performance and profitability, the investment climate could have negative effects obstructing investment incentives in agriculture. The study revealed eight key factors determining the investment climate in agriculture in Hanoi province, which include: land issue, provincial policies for agriculture, capital, physical infrastructure, administrative procedures, market, technology and labor issue. Land issues and provincial agricultural policies are the most important constraints; the second group are capital, physical infrastructure, governmental administration; and the third are market, technology and labor issues.

For a class of homogeneous hybrid systems we present a generalization to the hybrid systems framework of Chetaev's theorem and we propose a set of Lyapunov-like conditions for studying instability of the point x e = 0 and overshoots of solutions (namely when the norm of the solution vector x at some time instant exceeds the norm of the initial condition of x). Based on these results, we design a sum of squares algorithm that constructs a suitable Lyapunov-like function to fulfill such conditions. [less ▲]

Mycosubtilin, an antimicrobial lipopeptide, is produced by Bacillus subtilis strains. It belongs to the iturin family, which is characterized by the presence of a peptide part, constituted of a constant chiral amino acid sequence cycled by a β-amino fatty acid (Fig. 1). As all the iturinic lipopeptides, mycosubtilin exhibits its biocide activities on cytoplasmic membrane of target cells [1]. Recently, the activity of mycosubtilin on pathogenic strains resistant to classical agents was shown [2]. However, despite many works focused on its structure and the optimization of its production, only a few studies are conducted to analyze mycosubtilin-membrane interactions. The purpose of our work was to better understand, at the molecular level, the mechanisms of the mycosubtilin activity on cytoplasmic membranes. Firstly, we modelled the mycosubtilin-membrane interactions by using biomimetic monolayers and their associated techniques (tensiometry and PM-IRRAS). After characterizing the interfacial properties of pure mycosubtilin [3], we used Langmuir films to investigate the mycosubtilin behavior when the lipopeptide reaches the external leaflet of the membrane. We found that the mycosubtilin adsorption to lipid monolayers depended on their lipid composition and the lipopeptide interaction with the membrane was facilitated by the presence of sterols. Then, we mimicked the insertion of the lipopeptide in the whole membrane by using multilamellar vesicles. FT-IR spectroscopy analysis showed that the interaction of mycosubtilin with the artificial membranes induced conformational changes of the lipopeptide only in the presence of sterol. 1.

Since 1990s Vietnam is undergoing rapid industrialization with the national goal of becoming an industrial country. As a result, large tracts of agricultural land were conversed to industrial zones and clusters. This paper analyzes the complex impacts caused by industrialization on household food security. Both qualitative and quantitative methods were applied to investigate how land conversion process to industrial companies affected food security of different groups of peasant households in Hung Yen province, the most rapid industrialization province in Red River Delta of Vietnam. The study showed that industrialization and neo-liberalism affected household food security in three aspects: the lost of large agricultural land area which did not ensure stable jobs for peasants; the decline of living quality as a result of environmental pollution and high living costs; and the lost of household self reliance on food, with 77 percent of surveyed households not producing enough food for their own consumption. Industrialization had created a new class structure in the Vietnamese countryside with the rise of landless peasants who survived by selling their labor and who are net food buyers. The study contributes to the research that link the analysis of household food security with livelihood systems in the processes interacting across scales, from the very local to the global.

Nowadays, endocrine disruptor compounds in the water system have become a concern due to the risk of contamination to wild life and humans even at the nanogram level. Excess estrogens and androgens are a major contributor group of endocrine compounds. Statistical surveys have shown that dairy farms contribute to over 90% of the total estrogens in the UK and US. An analytical system is being developed to assess the efficiency of reactive materials to remove target hormonal contaminants from dairy farm effluent. This can be achieved using reporter gene assays (RGAs) to detect low level steroid hormones. A preliminary study comparing the efficiency of granular activated carbon, zero-valent iron, and organoclay was carried out using bench-scale evaluations in negative control HPLC water. Their potential ability to remove testosterone and 17- beta -estradiol spiked at reported environmental levels was measured by androgenic and estrogenic luminescent reporter assay respectively.

Towards a revison of the dairy cow’s standard for nitrogen production: justification and what are consequences for soil link rate of dairy farms. At present, the dairy cow’s standard of nitrogen production in Walloon region is 90 kg per year. This standard is used to calculate the “soil link rate” of farms, a balance between the organic nitrogen to be spread on land and the quantity legally authorized considering grassland and arable land area. This standard is appreciably lower than that fixed by other member states and was criticized by the European Commission during the negotiations having ended in the second program of sustainable nitrogen management. Further to new studies, it seems that the gaseous loss of nitrogen averages in buildings and during the storage is weaker than the 15% value which was used to justify this 90 kg standard. It also seems that there are big differences of average dairy production and average rate of urea according to the agricultural regions and consequently that regional production standards correspond better to the reality. On basis of these mean values, the dairy cow’s annual productions of nitrogen vary between 81 kg per year in grassy region of Fagne and 99 kg per year in Haute Ardenne and in grassy region from Liege. For the Walloon region in general, the average production is 94 kg per year. The adoption of different values of dairy cow’s nitrogen production by region would lead to an increase of 8% of the soil link rate of dairy farms in Haute Ardenne and of 7% in grassy region from Liege and a decrease of 7% in grassy region of Fagne.

DNA methylation and histone deacetylation are two key epigenetic modifications that play central role in regulation of gene expression. Several studies have shown that histone deacetylases (HDAC) and DNA methyltransferases (DNMT) inhibitors are potent antiangiogenic compounds. Though combination of HDAC and DNMT inhibitors are now being examined in clinical trials of hematological malignancies, very little work has been done to understand the effect of this combination on normal and tumoral angiogenesis. We have designed and tested a family of twin drugs with intrinsic HDAC and DNMT inhibitory activities in relevant models of angiogenesis in vitro (endothelial cells, pericytes and the 3D aortic ring assay) and in vivo (the chick chorioallantoic membrane assay). We have identified a lead compound having quantifiable antiangiogenic effect without cytotoxicity associated with increased global acetylation and decreased DNA methylation levels. This compound is presently used to develop effective approaches to treat cancer by modulating the process of angiogenesis. [less ▲]

Results of X-ray absorption fine structure measurements in manganites (La1-xHox)2/3Ca1/3MnO3 with 0.15 < x < 0.50 are presented. When LaMnO3 is doped with a divalent element such as Ca2+, substituting forLa3+, holes are induced in the filled Mn d orbitals. This leads to a strong ferromagnetic coupling between Mn sites. Ca ions in La1-xCaxMnO3 introduce a distortion of the crystal lattice and mixed valence Mn ions (Mn3+ and Mn4+). On the other hand, in manganites (La1-xHox)2/3Ca1/3MnO3 the substitution of La for Ho causes a lattice distortion and induces a disorder, which reduces a magnetic interaction. The ferromagnetic transition temperature and conductivity decrease very quickly with increasing x. The magnetic and transport properties of compounds depend on the local atomic structure around Mn ions. The information on the bond lengths and Debye–Waller factor are obtained from the extended X-ray absorption fine structure (EXAFS) data analysis. The charge state of Mn is determined from the position of the absorption edge in X-ray absorption near edge structure (XANES) data. XAFS results are in good agreement with magnetic characteristics of the studied materials. [less ▲]

In the literary papyri, the presence of a final, initial, or noted on a label title, not only identifies certainly the contents, but is often also, with other codicologic peculiarities, the indication of a copy of library. Do the Greek literary papyri of medicine present an indication of this kind? Under what shape(s) are identified the authors and the medical treatises? We try to answer these questions by examining not only the papyri the author of which is identified, but also the adespota where are quoted some titles, sometimes accompanied with the name of their author. Making it, we distinguish the titles "instruments" of the titles "references", which are mentioned by the very author or by the other authors. [less ▲]

The aim of this study was to examine correlations between impaired memory acquisition/consolidation and brain metabolism at rest in Alzheimer’s disease. 44 confirmed Alzheimer patients (AD), 16 patients with mild cognitive impairment (MCI) who converted to AD (MCI-C) (4-8 years of follow-up), 15 MCI patients who remained stable and 12 healthy elderly controls were administered the California Verbal Learning Task (CVLT) at entry. Acquisition and consolidation memory scores were calculated respectively as mean gained and total lost access across the 5 study-test trials (p = 0.05). Brain metabolism was measured by 18FDG-PET. Cognitive-metabolic correlations were performed with SPM8 (p<0.05 uncorrected). Mean gained access was significantly lower in the AD group than in the control and MCI-S group and was significantly lower in the MCI-C group than in the control group. Mean gained access was significantly correlated to metabolism in the left precentral gyrus and IPS fondus in the control group, in the left and right inferior parietal lobules in the MCI-S group and in the left hippocampus in the AD group. Total lost access was greater in AD patients compared to control participants. No significant correlation between total lost access and brain metabolism was found. The acquisition process is impaired in AD patients at a very early stage of the disease (MCI-C). This deficit is linked to metabolic changes in a frontoparieto-hippocampal learning network. In addition, consolidation process is specifically impaired in confirmed AD patients, while this deficit was not significantly correlated to brain metabolism in our participant groups. [less ▲]
