    • Effects of geometric constraints on the nuclear multifragmentation process 

      Souza, Sergio Ricardo de Azevedo; Donangelo, Raul José; Lynch, William G.; Tsang, M. B. (2007) [Artículo de periódico]
      We include in statistical model calculations the facts that in the nuclear multifragmentation process the fragments are produced within a given volume and have a finite size. The corrections associated with these constraints ...

    • Experimental analysis of lateral impact on planar brittle material 

      Santos, Filipe Pereira Mesquita dos; Barbosa, Valmar Carneiro; Donangelo, Raul José; Souza, Sergio Ricardo de Azevedo (2010) [Artículo de periódico]
      The fragmentation of alumina and glass plates due to lateral impact is studied. A few hundred plates have been fragmented at different impact velocities and the produced fragments are analyzed. The method employed in this ...

    • Experimental analysis of lateral impact on planar brittle material : spatial properties of cracks 

      Santos, Filipe Pereira Mesquita dos; Barbosa, Valmar Carneiro; Donangelo, Raul José; Souza, Sergio Ricardo de Azevedo (2011) [Artículo de periódico]
      The breakup of alkaline glass and alumina plates due to planar impacts on one of their lateral sides is studied. Particular attention is given to investigating the spatial location of the cracks within the plates. Analysis ...

    • Nova urbanização fragmentada na região metropolitana de Porto Alegre: o caso de águas claras - Viamão/RS como exemplo de análise 

      Martins, Samuel; Strohaecker, Tania Marques (2013) [Artículo de periódico]
      As manifestações intraurbanas da globalização fragmentadora, chanceladas pelos agentes produtores do espaço urbano, que visam prioritariamente à reprodução do capital, condicionam a configuração da estrutura urbana em ...

    • Probing the symmetry energy from the nuclear isoscaling 

      Souza, Sergio Ricardo de Azevedo; Tsang, M. B.; Donangelo, Raul José; Lynch, William G.; Steiner, Andrew W. (2008) [Artículo de periódico]
      Using different parametrizations of the nuclear mass formula, we study the sensitivity of the isoscaling parameters to the mass formula employed in grand-canonical calculations. Previous works on isoscaling have suggested ...
