En 140/39 av. J.-C., une mission romaine composée, entre autres, de Scipion Emilien et du philosophe Panétios visita les alliés orientaux de Rome et se rendit notamment à Alexandrie. Le roi Ptolémée VIII y accueillit officiellement ces hôtes prestigieux, vêtu d’un habit étrange : un chiton long et subtil, dont les auteurs anciens réfèrent unanimement l’effet efféminé et caricatural, au point de susciter le rire des Romains et une condamnation du luxe effréné et décadent du royaume égyptien par comparaison avec la sobriété romaine. Il a fallu attendre une étude de H. Heinen en 1983 pour reconnaître, d’une part, l’envergure idéologique du lien entre la tenue de Ptolémée VIII – en fait empruntée à l’iconographie hellénistique de Dionysos – et la mise en scène officielle de la tryphè et du pouvoir royal et, de l’autre, le sens politique de la représentation caricaturale qu’en donna probablement déjà Panétios, représentation qui fut relayée et amplifiée par toute une tradition historiographique philo-romaine, qui se développa tout au long de la conquête romaine de la Méditerranée et ensuite à l’occasion du conflit entre Octavien et Antoine. Cette tradition nous a transmis, par le biais des auteurs de l’époque impériale, un discours fondé sur l’opposition entre Rome (et l’Italie), vertueuse source de citoyens et de soldats, et l’Orient dégénéré. Dans un tel cadre, Dionysos et le dionysisme sont sollicités pour servir à la construction d’un modèle accusatoire contre les ennemis de Rome, incarnant le désordre dans une dimension à la foi individuelle et institutionnelle. Mais est-ce que cette vision idéologique nous donne un portrait satisfaisant des rapports réels entre Rome et Dionysos / Bacchos / Liber Pater ? En partant de cette question, je propose dans ma contribution une approche visant à analyser, à l’aide de sources aussi littéraires que documentaires, les contextes de contact entre Rome et Dionysos de l’époque hellénistique au début du Principat, pour essayer de mettre en relief les relations entre, d’une part, la répulsion et le refus idéologiques du dionysisme, de l’autre les démarches d’appropriation et d’adaptation, à la culture romaine, de traits caractérisant les cultes hellénistiques de Dionysos et leurs utilisation dans la mise en forme des pratiques du pouvoir et de leurs représentations.

Wireworms (Coleoptera: Elateridae) are important soil dwelling pests worldwide causing yield losses in many crops. The progressive restrictions in the matter of efficient synthetic chemicals for health and environmental care brought out the need for alternative management techniques. This paper summarizes the main potential tools that have been studied up to now and that could be applied together in integrated pest management systems and suggests guidelines for future research.

In current wind design practice, static wind loads are usually defined to obtain, by simple static analyses, the extreme values of any structural response that would be formally obtained with a strict dynamic buffeting analysis. The minimum and maximum values that may reach any response define the envelope. Equivalent static wind loads (ESWLs) allow to recover extreme responses in the envelope. As a first objective, this paper formalizes a general method to determine ESWL, in a nodal basis, by extending the concept of load-response correlation, which is only valid in the background range. The general method, the displacement-response-correlation (DRC) method, covers the background and resonant contributions of the considered response. As a second objective, the paper addresses the problem of building a set of static wind loads that adequately reconstructs the envelopes of responses. The concept of principal static wind loads (PSWL) is introduced to form a reduced basis of representative loads well-suited for envelope reconstruction. Its optimality is demonstrated both analytically and with a detailed illustrative example. [less ▲]

En 2000, Henri Mayr-Harting contesta l’idée qu’Arnold Angenendt se faisait de la religion de Charlemagne . Au modèle d’une religion magique, essentiellement propitiatoire, il opposa un certain génie éthique carolingien teinté de quelques supports quasi-magiques et posa les jalons d’une enquête sur le sens profond de la religion de Charlemagne, son contenu éthique et son objet. Tout en admettant qu’on ne connaîtrait jamais les convictions personnelles de Charlemagne, il a avancé l’hypothèse qu’on était en mesure d’entendre sa voix dans certains documents faisant échos à un débat qui aurait opposé différents membres de la cour. Confortée par les recherches d’Henry Mayr-Harting, cette conférence visait à évaluer la sincérité des convictions religieuses de celui qui déploya tous les moyens matériels, militaires et humains qu’il avait à sa disposition, pour enseigner à son peuple ce qu’il était nécessaire de croire pour être sauvé.

This research starts from a lack of conceptualisation, in the architectural field, around the notion of non-figuration. Postmodern Movement’s ideological opposition to Modern Architecture and its ascetic aesthetic led to the promotion of signs and images. This prevents a reading of Modern Architecture around notions such as openness, opacity linked to non-figuration as defined by Umberto Eco in his essay Opera Operta. U. Eco’s literary analysis finds a relevant synthesis in G. Deleuze’s work who develops three approaches of non-figuration in pictural art : abstract art (P. Mondrian), figural art (F. Bacon) and informal art (J. Pollock). These categories represent a specific way of exceeding figuration and forms in favour of the forces on the canvas. The thesis aims at evaluating the applicability of these categories to Modern Architecture. The study of three architectural theorists - R. Venturi, C. Norberg-Schulz and C. Rowe - allows us to clarify non-figuration in architecture. This leads to point two specific constraints: functionality and presence that involve architecture in a figurative field. The thesis than articulates architecture’s specific restrictions to non-figuration with G. Deleuze’s aesthetic and philosophy. The analysis of P. Eisenman, L.I. Kahn, Le Corbusier and Mies van der Rohe’s buildings show progressively the necessity to enrich architecture with irrationality, a way of exceeding figurative content. Finally, the thesis discusses the theoretical issues of this approach and examines the possibility to analyse architectural history with non-figurative concepts developed in this research. These kinds of processes, freed of their stylistic content, allow, for example, Modern Architecture and Baroque to get closer. This work also establishes the possibility to develop similar processes of analysis between the different artistic fields (painting, literature, architecture) with same results. [less ▲]

Viral tumor models have significantly contributed to our understanding of oncogenic mechanisms. How transforming delta-retroviruses induce malignancy however remains poorly understood, especially as viral mRNA/protein are tightly silenced in tumors. Here, using deep sequencing of broad windows of small RNA sizes in the Bovine Leukemia Virus ovine model of leukemia/lymphoma, we provide in vivo evidence of the production of non-canonical Pol IIItranscribed viral microRNAs in leukemic B-cells in the complete absence of Pol II 5’ LTR-driven transcriptional activity. Processed from a cluster of five independent self-sufficient transcriptional units located in a proviral region dispensable for in vivo infectivity, BLV microRNAs represent ~ 40 % of all microRNAs in both experimental and natural malignancy. They are subject to strong purifying selection and associate with Argonautes, consistent with a critical function in silencing of important cellular and/or viral targets. BLV microRNAs are strongly expressed in preleukemic and malignant cells in which structural and regulatory gene expression is repressed, suggesting a key role in tumor onset and progression. Understanding how Pol III-dependent microRNAs subvert cellular and viral pathways will contribute in deciphering the intricate perturbations that underlie malignant transformation. [less ▲]

This thesis used an integrated approach to develop options for the control of cereal and legumes insect pests in Senegal combining laboratory and field tests. A diagnostic survey was conducted to fully understand current storage practices and control methods in foods and seeds. The study focused on traditional practices from the eastern parts of Senegal to develop options in harmony with the populations concerns. Boscia senegalensis is a plant known for its medicinal properties and its food use was the first plant to be tested for the control of Caryedon serratus, the groundnut weevil. We observed that fruits (3% w/w) and crushed leaves (6% w/w) of this species protected groundnuts. B. senegalensis was subsequently used for protection of cowpea, millet and maize against Callosobruchus maculatus, Tribolium castaneum, Sitophilus zeamais and Prostephanus truncatus. Only T. castaneum was insensitive to this plant at low concentrations. Methylisothiocyanate (MITC) is the main active ingredient of this plant liberated from glucocapparin. This molecule can reach C. maculatus and C. serratus larvae and eggs which develop inside grains but concentrations need to be two to four times higher than adults. Ripe fruits still proved to be effective but immature fruits had a higher efficacy. Residues of MITC were detected in the stored grains after treatment, but the treatment had no effect on germination of stored grains. During the study a reliable and effective method to analyze glucocapparin in leaves and fruits of B. senegalensis was developed, during two years in four localities showing an apparently very marked “soil effect”. Highest glucocapparin concentrations were recorded in January at the beginning of dry season and the lowest during the rainy season from August to November, independent of locality. Powdered maize cobs were effective in maintaining maize grain quality in laboratory studies. Observed damage and losses were respectively 5 and 1% at 2.4% (w/w). At higher doses, mixing of powdered maize cobs with grains offered equal protection as Actellic (pyrimiphos-methyl). The efficacy of this control method was tested during two years in farmer’s granaries confirmed the validity of the laboratory tests. The traditional practice of incorporating insecticidal plants within the storage structure did not impact development of pests already established in the granaries. By contrast, storage of maize cobs using a sandwich method with Hyptis spicigera proved to be effective against storage pests. In addition, the storage of non-winnowed maize grains offered a substantial degree of protection against insect infestations. Their composition was carried out by GC-MS/GC-FID analyses. [less ▲]

Y a-t-il encore une place, dans une approche intentionnelle de l’esprit, pour l’idée d’un « donné sensible » ou pour celle d’un caractère phénoménal de l’expérience sensorielle ? L’analyse des sensations est-elle conciliable, d’une manière ou d’une autre, avec l’analyse intentionnelle ? Plus particulièrement : doit-on faire droit à un mode de présentation intentionnel-phénoménal (« contenu phénoménal » : l’apparaître-rouge de la rose) qui ne serait pas réductible à un mode de présentation conceptuel ou linguistique (contenu conceptuel : la rose perçue en tant que rouge) ? Et si oui, quel serait le statut d’un tel « contenu phénoménal » ? [less ▲]
