None (Members of Erysiphales cause powdery mildew diseases on wide host rang and produce whitish primary mycelium on surface of infected parts. Based on microscopic study of one specimen on Jasminum sp., structures of fungus including conidiophores and conidia were observed. Foot cells of conidiophores were cylindrical or curved in basal part, followed by 1-2 shorter cells. Conidia were ellipso...

Let k an algebraically closed field, P the n-dimensional projective space over k and TPn the tangent vector bundle of P . In this paper I prove the following result : for every integer l, for every non-negative integer s, if Zs is the union of s points in sufficiently general position in P, then the restriction map H(P, TPn(l)) → H 0(Zs, TPn(l)|Zs) has maximal rank. This result implies that the...

During priming of pop-out, performance at discriminating a pop-out feature target in visual search is affected by whether the target on the previous trial was defined by the same feature as on the upcoming trial. Recent studies suggest that priming of pop-out relies on attentional processes. With the use of simultaneous, combined transcranial magnetic stimulation and event-related potential rec...

Cet article présente une analyse statistique de la position des économistes français et des spécialistes français des sciences de gestion parmi les chercheurs européens de haut rang. La preuve empirique révèle que la France ne développe pas fortement ses ressources humaines sur la scène internationale. La position de la France en Europe, repérée par les citations (pour les économistes) et les n...
