The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the fermi energy *** a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy *** the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been *** main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their *** emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear *** evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport *** approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMfs close to the heavy *** deviations from sequential processes were found for those IMfs in the region of masses intermediate between the mass of heavy residues and the mass of light *** simulations are in *** experimental analysis will be enriched also by information obtained inspecting the IMf-IMf correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having

“稳定的”视神经疾病患者的迟发性视力减退

世界核心医学期刊文摘（眼科学分册） 2005年第12期1卷 30-30页

作者： Kim J.W rizzo J.f Lessell S 潘佳鸿 243 Charles St BostonMA02114United States.Dr

Background: Histological studies on the human optic nerve have documented decreasing axonal nerve fiber counts with age. In patients with optic atrophy, a nonpathological dropout of ganglion cell axons as part of the normal aging process may become clinically significant. Objective: To describe the occurrence of delayed visual loss in patients with presumably “ stable” optic neuropathy. Methods: We reviewed the medical records of 3 patients who experienced slowly progressive visual loss in adulthood after suffering childhood optic nerve injury. Results: All 3 patients had a monophasic illness in childhood that caused bilateral optic atrophy and visual impairment. following decades of stability, each suffered a gradual, symptomatic visual decline that extended over years. No new ophthalmologic, systemic, or neurologic disorder was found that explained the visual decline in any of these patients. Conclusion: We hypothesize that the late visual decline in these 3 patients resulted from deleterious effects of age-related axonal loss on an already depleted population of neurons.
