The common bean (Phaseolus vulgaris L.) is one of the principal food crops of Rwanda. It is cultivated by 97% of the farms and constitutes the principal source of proteins for the majority of the Rwandan population. One observes since 2000 a considerable reduction in the bean outputs; among the principal causes, one can quote the transmitted diseases and damage caused by insects. In order to contribute to the production of healthy seeds and plant of bean, a test was carried out (February-May 2009) to the station of Rubilizi-ISAE Busogo, from which the objective was to protect the plants of bean against the attacks of insects during the first 8 weeks by coating the seeds with the imidacloprod-gaucho in order to avoid the viral diseases on the plants which result from these seeds and to also thwart the attacks of the principal devastating insects of the bean among which there were the black bean aphid (BBA), Aphis fabae, vector of bean common mosaic virus and the bean stem maggot (BSM), Ophiomyia spp. Three doses of imidacloprid-gaucho were compared to the control, namely 2, 4 and 6g of active matter per kilo of seeds. The results made possible to draw the following conclusions: - the imidacloprid expressed its effects up to eight weeks after sowing; indeed one recorded few close Bean Common Mosaic Virus-attacked plants (less than 3%) until 56 days after sowing; the percentage of virus attacked plant increased beyond to reach 42% for the dose of 2g of imidacloprid per kilo of seeds and only 25% maximum for 4 and 6g of the insecticide product per kilo of seeds; - the imidacloprid allowed also to control the Bean Stem Maggot in the proportion of 58%, 44%, 22% and 18% respectively for the control (0 g), 2, 4, and 6 g of the product per kg of seeds. Within the sight of these results, we can recommend the producers, the pelleting of bean seeds to the dose 4g of imidacloprid-gaucho per kilo of seeds within the framework of the integrated pest management (IPM) against the common mosaic and the damage of Black Bean Aphids and Bean Stem Maggots.

Acute coronary syndromes: considerations for improved acceptance and implementation of management guidelines.

The management of acute coronary syndrome in Europe is covered by various European Society of Cardiology guidelines, which although valuable, are complex and may not always provide clear guidance in everyday clinical practice. Consequently, implementation of the guideline recommendations is frequently suboptimal. To complicate matters further, a wealth of new data from large trials examining novel anti-thrombotic agents will become or are already available, necessitating guideline updates. This article summarizes the gaps between current guideline-recommended treatment of acute coronary syndrome and daily practice as dictated by the evidence base, including recent trials. Reasons for the suboptimal implementation of the current European Society of Cardiology guidelines and possible solutions to making these more practice oriented are presented. [less ▲]

Early detection of alien plants in xeric Natura 2000 sites in Southern Belgium

The Natura 2000 network consists of sites designated by the member States of the European Union, under the Habitats and Birds Directives. Setting up that network is one of the biggest challenge in nature conservation in Europe, since habitats and species for which Natura 2000 sites are designated must be maintained in a “favorable conservation status”. Little is known so far, however, about how Natura 2000 sites are invaded by exotics species. Xeric habitats of high biological value included in the Natura 2000 network are among the most species-rich in Southern Belgium. They include calcareous grasslands, sandy meadows, dry heathlands, boxwood stands, siliceous rocks and calcareous rocks. We randomly sampled 15% of sites in each of these six categories (with a minimum of five sites per category) , with a total of 86 sites out of 470 existing sites. In each site, we recorded the presence/absence of 63 alien plants know to develop in xeric habitats (species list based on Verloove (2006) and expert’s personnal observations.), and estimated species cover. 25 naturalized alien plant species were observed in xeric habitats of the Natura 2000 network in Southern Belgium. Generally, alien species populations were still limited. [less ▲]

Le sens de l'idéalisme platonicien selon Lotze

J'analyse ici l'interprétation très influente que Lotze a donnée de la théorie platonicienne des Idées au troisième livre de sa grande "Logique" de 1874. Je commence par rappeler l'influence de cette interprétation sur l'anti-psychologisme, aussi bien dans sa version néokantienne que dans sa version husserlienne et frégéenne. Puis je la replace dans son contexte en distinguant certaines thèses philosophiques (le rejet du correspondantisme) et certaines thèses historiques sur Platon (caractère logique de sa théorie des Idées, prédominante du vocabulaire ontologique dans la langue grecque, etc.). Enfin, je passe en revue les principales objections qui ont été adressées à l'interprétation lotzéenne, notamment par Natorp et Heidegger. [less ▲]
