Top quark mass measurement with ATLAS

The top quark mass measurement with ATLAS in the lepton plus jets channel is summarized from the perspective of the early data. Using the invariant mass of the three jets arising from the hadronic side as the estimator of the top quark mass, a precision of the order of 1 to 3.5 GeV on the top quark mass measurement should be achievable, assuming a jet energy scale uncertainty of 1 to 5%.Comment: Poster session at ICHEP08, Philadelphia, USA, July 2008. 3 pages, LaTeX, 3 eps figure

TRANSPOSITION DU CONCEPT D'HETEROSIS DU MAIS AUX PROFESSIONNELS AGRICOLES Analyse lexicale et phrasique

International audienceLa recherche qui est présentée ici a été menée en mémoire de ΌΕΑ de didactique des disciplines scientifiques à Lyon 1. Nous avons effectué une analyse linguistique de textes de professionnels du milieu agricole. Par ce travail nous voulions analyser la transposition didactique d'un savoir biologique, agronomique dans le cadre non formel de l'information professionnelle, les transformations que ce savoir subä et le type d'information qui parvient aux agriculteurs

Driver-pressure-impact and response-recovery chains in European rivers: observed and predicted effects on BQEs

The report presented in the following is part of the outcome of WISER’s river Workpackage WP5.1 and as such part of the module on aquatic ecosystem management and restoration. The ultimate goal of WP5.1 is to provide guidance on best practice restoration and management to the practitioners in River Basin Management. Therefore, a series of analyses was undertaken, each of which used a part of the WP5.1 database in order to track two major pathways of biological response: 1) the response of riverine biota to environmental pressures (degradation) and 2) the response of biota to the reduction of these impacts (restoration). This report attempts to provide empirical evidence on the environment-biota relationships for both pathways
