The Northeast will once again host an Annual Meeting of SBTE taking place from 18 to 20 August 2011. The scenario this time was chosen the outstanding beach of Cumbuco - Ceará, an obligatory stop for visitors to Ceará, located approximately 30 km from Fortaleza. The beach is one of the most important tourist facilities in the state, with more than 40 inns and hotels, and about twenty restaurants specializing in regional and international cuisine, able to please the most discerning palates. Cumbuco is also very popular destination for sportsmen in the world, because the strong winds of the place attract athletes to the windsurfing and kiteboarding. For all these reasons, we could not have chosen a better place to accomplish our XXV Annual Meeting. Under the tropical paradise of sun, the participants of this event will also be illuminated by the most current scientific knowledge, passed on by their own creators: renowned Brazilian and foreign researchers. As usual, the board of SBTE endeavored greatly to us all to enjoy wonderful and memorable moments experienced during the 25th Annual Meeting of the SBTE.
