These proceedings assemble some fundamental contributions whose topics consist of interesting problems in nuclear and particle physics. Specific works about Heavy Flavors Physics, Theoretical Physics, High Energy Colliders, Nuclear Physics, Neutrino Physics are presented; new experimental results and devices are also discussed in a detailed way. From the theoretical point of view, many problems of QCD are examined and solved using non-conventional ideas.These contributions point the way towards new frontiers in nuclear and hadronic physics.Key Speakers: R Baldini-Celio, E Bellotti, A Bertin, R Bertini, C Caso, E Del Giudice, G Moneti, G Pancheri, G Preparata, A Vitale, J Weber.
