The zero-temperature Glauber dynamics is used to investigate the persistence probability P (t) in the Potts model with Q = 3, 4, 5, 7, 9, 12, 24, 64, 128, 256, 512, 1024, 4096, 16384,..., 230 states on directed and undirected Barabási-Albert networks and Erdös-Rényi random graphs. In this model it is found that P (t) decays exponentially to zero in short times for directed and undirected ErdösR...

We propose a topological Chern-Simons term in D = 5 dimensions coupled to Einstein Hilbert theory. Hartree approximation for topological Lagrangian and the Chern-Simons term in D = 3 is considered. An effective model of Quantum Gravity in D = 5 dimensions is presented here. The analysis of residues is considered and the unitarity is guaranteed at tree level. The propagator is ghost and tachyon ...

Nursing School of Universidade Federal do Rio Grande do Sul: 60 years of conquests and challenges.

On December 4th, 2010, the Nursing School of Universidade Federal do Rio Grande do Sul celebrated 60 years. After six decades, the institution is in good shape and recognized academically. Created in 1950, the School was a landmark, for it was the first Nursing School in the Southern Region of Brazil. However, maintain and expand it is a daily challenge for its faculty and staff. In 1966, the S...
