The process of internalization of development occurred in the state of Sao Paulo resulted in accelerated growth of intermediate cities leading to a pattern of development with sprawl, segregation and suburbanization. In this process stands the Administrative Region of Campinas, the hinterland region of higher growth and accumulating a larger number of medium-sized cities. Such questions imply the need for appropriate urban policies to confront these challenges, under risk to jeopardize the quality of life and environment of these cities. The implementation of the Estatuto da Cidade brings new perspectives for urban management in medium-sized cities. This study aims to evaluate the deployment of instruments of urban management in medium-sized cities in São Paulo, with emphasis on Administrative Region of Campinas, based on the Profile of Brazilian Municipalities 2008 conducted by IBGE. The results point to a worrying situation, as it did not see a correlation between the deployment of these instruments and the size, growth and income in the mid-sized cities.

This paper proposes a solution to improve the performance of the first order Early Error Sensing (EES) Adaptive Time Delay Tanlock Loops (ATDTL) presented in (Al-Zaabi, Al-Qutayri e Al-Araji, 2005), regarding to frequency estimation and tracking time. The EES-ATDTL are phaselocked-loops (PLL) used to hardware implementations, due to their simple structure. Fixed-points theorems are used to determine conditions for rapid convergence of the estimation process and a estimative of the frecuency input is obtained with a Gaussian filter that improves the gain adaptation. The mathematical models are the presented by (Al-Araji, Al-Qutayri e Al-Zaabi, 2006). Simulations have been performed to evaluate the theoretical results.

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report one case of DENV-1/DENV-4 co-infection in human serum detected by molecular tests. Phylogenetic analysis of the sequences obtained indicated the presence of genotype V and II for DENV-1 and DENV-4, respectively.
