  24. CONCLUSION • ALICE is collecting data and producing papers. Computing and Upgrade? • The first experimental campaign with the AGATA demonstrator has started at LNL. The realization of ¼ of solid angle is in progress. Nuclei at extremes are being investigated. • Esperiments engaged in upgrades • such as JLAB and LUNA are progressing. • Several relevant results are obtained with the analysis of experiments under way. They are important to guide the future programs. • We count on the activity at JLAB • for which also in the future (as in the past) we expect outstanding results !
