Neutrino events collected by this detector are used in order to study the atmospheric neutrino flux. Different measurements in different energy samples are in full agreement and show evidence of neutrino oscillation phenomenon. Also the search for neutrino astrophysical sources is reported.3 pages, 6 figures, Physics in Collision, Stanford, California, 2002, THAP04High Energy Physics - Experimenttext
