The ground-state phase diagram of an Ising spin-glass model on a random graph with an arbitrary fraction w of ferromagnetic interactions is analysed in the presence of an external field. Using the replica method, and ...

Objectives: To determine the marginal adaptation of bulk-fill composites in class II MO cavities.Methods: Standardized class II MO cavities with bevelled enamel margins were prepared in 40 extracted human molars. The teeth ...

Este estudo objetivou: (1) comparar a topografia superficial e a interface entre a obturação e as paredes do canal de raízes seccionadas com laser, ultra-som ou broca; (2) avaliar o efeito do preparo retrógrado com retropontas ...
