155. CULTURE BIOLOGIQUE DE LA LIME DE TAHITI A LA MARTINIQUE

Author

Abstract

Organic agriculture in Citrus cultivation in Martinique seems to be very difficult regarding high pests and diseases pressure in the tropical area. A comparison between standard and organic cultivation of Tahiti Lime shows that the main constraints are located in the weed control and also in the high price of nutritional input approved for organic farming. The yield cumulated during the four first years is similar for both crop managements.

Abstract

National audience; Pollen dispersal over short and intermediate distances (generally less than 100m) has been the topic of numerous experimental and theoretical studies (Eastham & Sweet, 2002). Particular importance has been given to the intra-field dispersal (i.e. homogeneous canopy and distances around 100m) and to the effects of discontinuities in the canopy (non cultivated areas, or areas cultivated with non-studied species). A precise description of intermediate distance dispersal and a better understanding of gap effects on pollen dispersal are necessary to predict the cross-pollination rates between two close fields or the genetic pollution within a field that originates from undesired plants (cultivated, feral or wild) in the vicinity. However, it has become relevant to understand pollen dispersal on the larger scale of agricultural landscapes (distances of several kilometers). This is true in agronomy for issues relative to GM and non GM co-existence by defining spatial patterns of fields grown with different varieties, as well as in population biology for issues relative to gene flow between fields and feral or wild populations. Thus, it is necessary to work on the means to extrapolate the dispersal functions fitted to experimental data collected in an homogeneous canopy and only over intermediate distances in order to apply them to a broad range of distances and situations. In this paper, we present concepts to investigate the role and importance of long-distance dispersal regarding mainly the properties of dispersal function tails.; De nombreuses études expérimentales et théoriques se sont attachées à décrire la dispersion du pollen à courtes et moyennes distances (moins de 100 m en général), que ce soit en milieu continu (la surface considérée est couverte de manière homogène par l'espèce considérée) ou lors de l'étude de l'effet de discontinuités (surfaces non cultivées ou couvertes par une autre espèce) sur la dispersion du pollen. Ces études sont fondamentales lorsque l'on cherche à comprendre et prédire les taux de pollinisation croisée entre deux champs voisins ou les taux de pollution génétique engendrés par des plantes indésirables au sein d'une parcelle ou à proximité. Cependant, que ce soit dans une optique de ségrégation de filières par une spatialisation des variétés ou pour des questions de biologie des populations relatives aux flux de gènes entre champs et populations hors-champs ou sauvages, il devient nécessaire de comprendre les flux de gènes à l'échelle plus large d'un paysage agricole (de l'ordre de quelques kilomètres). Il est donc nécessaire de travailler sur les possibilités d'extrapolation à l'échelle du paysage des fonctions de dispersion obtenues en milieu continu pour les courtes et moyennes distances. Nous présentons donc ici quelques travaux qui explorent les propriétés des queues de fonctions de dispersion. Ces travaux sont basés sur la dispersion du pollen de colza pour laquelle des fonctions de dispersion ont été obtenues par ajustement sur des données expérimentales (Inra Rennes). Nous présentons ces données et les ajustements réalisés dans la première partie. Des prédictions de taux de pollinisation croisée ont alors été réalisées en extrapolant les fonctions obtenues à de plus grandes distances (300 m) et confrontées à des données obtenues par le Cetiom (partie 2). Enfin, des modèles à l'échelle du paysage permettent de comprendre l'importance du poids de la queue de dispersion sur le mélange des pollens provenant de différentes sources. En particulier, le fait que la fonction de dispersion ait une queue à décroissance plus lourde que la dispersion exponentielle à un effet bien plus fondamental que la distance moyenne de dispersion (partie 3).

Abstract

A 75-year-old woman followed for Wegener's disease was hospitalized for pleural effusion. The clinical presentation and cytology of the pleural fluid suggested the diagnosis of purulent pleurisy in this immunodepressed patient. The final diagnosis was a pleural involvement of Wegener's disease, a rarely described localization, as proven by the typical pathology findings.

172. Properties of a carbon-fibre composite modified by electrospun poly (vinylidene fluoride)

Abstract

The interlaminar toughening of a carbon-fibre reinforced composite by incorporation of electrospun polyvinylidene fluoride (PVDF) nanofibrous membranes was explored in this work. The nanofibres were electrospun directly onto commercial pre-impregnated carbon fibre materials under optimised conditions and PVDF was found to primarily crystallise in its β phase polymorphic form. There is strong evidence from DMTA analysis to suggest that a partial miscibility between the amorphous phases of the PVDF nanofibres and the epoxy exists. The improved plastic deformation at the crack tip after inclusion of the nanofibres was directly translated to a 57% increase in the mode II interlaminar fracture toughness (in-plane shear failure). Conversely, the fracture toughness in mode I (opening failure) was slightly lower than the reference by approximately 20%, and the results were interpreted from the complex micromechanisms of failure arising from the changes in polymorphism of the PVDF.
