static int8_t *g_sdus[] = {"En dépit de son volontarisme affiché, le premier ministre est de plus en plus décrié pour son incompétence. La tension politique et dans l'opinion publique est encore montée d'un cran au Japon, sur fond d'inquiétantes nouvelles, avec du plutonium détecté dans le sol autour de la centrale de Fukushima. Le premier ministre Naoto Kan a solennellement déclaré que son gouvernement était «en état d'alerte maximum». Tout en reconnaissant que la situation restait «imprévisible». Ce volontarisme affiché par le premier ministre - que Nicolas Sarkozy rencontrera demain lors d'une visite au Japon - ne l'a pas empêché d'être la cible de violentes critiques de la part de parlementaires sur sa gestion de la crise. Attaqué sur le manque de transparence, il a assuré qu'il rendait publiques toutes les informations en sa possession. Un député de l'opposition, Yosuke Isozaki, a aussi reproché à Naoto Kan de ne pas avoir ordonné l'évacuation des populations dans la zone comprise entre 20 et 30 km autour de la centrale. «Peut-il y avoir quelque chose de plus irresponsable que cela ?», a-t-il lancé. Pour l'heure, la zone d'évacuation est limitée à un rayon de 20 km, seul le confinement étant recommandé pour les 10 km suivants. Sur ce sujet, les autorités japonaises ont été fragilisées mardi par les déclarations de Greenpeace, affirmant que ses experts avaient détecté une radioactivité dangereuse à 40 km de la centrale. L'organisation écologiste a appelé à une extension de la zone d'évacuation, exhortant Tokyo à «cesser de privilégier la politique aux dépens de la science». L'Agence japonaise de sûreté nucléaire a balayé ces critiques.",

                           "La pâquerette (Bellis perennis) est une plante vivace des prés, des pelouses, des bords de chemins et des prairies, haute de dix à vingt centimètres, de la famille des Astéracées, dont les fleurs naissent sur des inflorescences appelées capitules : celles du pourtour, que l'on croit à tort être des pétales, appelées fleurs ligulées, parce qu'elles ont la forme d'une languette, ou demi-fleurons, sont des fleurs femelles, dont la couleur varie du blanc au rose plus ou moins prononcé ; celles du centre, jaunes, appelées fleurs tubuleuses, parce que leur corolle forme un tube, ou fleurons, sont hermaphrodites. Ainsi, contrairement à l'opinion populaire, ce qu'on appelle une « fleur » de pâquerette n'est en réalité pas « une » fleur mais un capitule portant des fleurs très nombreuses.Leurs fruits s'envolent grâce au vent et dégagent des odeurs qui attirent les insectes.Une variété muricole peut pousser sur des murs humides verticaux.Les pâquerettes sont des fleurs rustiques et très communes en Europe, sur les gazons, les prairies, les chemins et les zones d'herbe rase.Elles ont la particularité, comme certaines autres fleurs de plantes herbacées, de se fermer la nuit et de s'ouvrir le matin pour s'épanouir au soleil ; elles peuvent aussi se fermer pendant les averses, voire un peu avant, ce qui permet dans les campagnes de prédire la pluie légèrement à l'avance.",
