2. Um esquema de seleção de rotas para o balanceamento de segurança e desempenho em redes em malha sem fio / Um Esquema de Seleção de Rotas para o Balanceamento de Segurança e Desempenho em Redes em Malha Sem Fio
Wireless mesh networks (WMNs) have been used to support multimedia applications on different domains, such as health care and entertainment, that require high levels of security and performance simultaneously. Those networks comprise of a wireless backbone of routers that cooperate to provide data communication among mobile devices, such as notebooks, PDAs a

3. Distance education and Aberta University of Brazil when the mercantilization of teaching and the precariousness of teaching reach a new height / EducaÃÃo à DistÃncia e Universidade Aberta do Brasil: quando a mercantilizaÃÃo do ensino e a precarizaÃÃo da docÃncia alcanÃam um novo Ãpice?
Taking as reference onto-methodological the Marxist critique of the capitalist system, we will explain the current moment of capitalism, from the contributions of IstuÃn MÃszÃros about what he calls sociometabolic system of the capital. At the structural crisis of this system the production is characterized as destructive being growing the context of the

4. Simulação Computacional e Análise de um Modelo Fenotípico de Evolução Viral. / Computer Simulation and Analysis of a Phenotypic Model of Viral Evolution
A large amount of viruses of medical importance such as HIV, respiratory syncytial virus, the hepatitis C virus, influenza A (H1N1) and polio virus, has RNA genome. These viruses exhibit extremely high mutational rate, fast replicative kinetics, large population of particles and high genetic diversity. Manifested during the infectious process, these features

5. A novel indicator reaction for the catalytic determination of V(V) at ppb levels by the kinetic spectrophotometric method
A novel sensitive and relatively selective kinetic method is presented for the determination of V(V), based on its catalytic effect on the oxidation reaction of Ponceau Xylydine by potassium bromate in presence of 5-sulfosalicylic acid (SSA) as activator. The reaction was monitored spectrophotometrically by measuring the decrease in absorbance of Ponceau Xyl

6. Modelagem do crescimento e da produção de povoamentos de Tectona grandis submetidos a desbaste / Modeling growth and production of stands of Tectona grandis
The objective of this study was to construct a model of growth and production, simulate alternative management stands of teak submitted to selective thinning and evaluate the effectiveness of the selective sampling to obtain data for the modeling of growth and production. The Clutter model was adjusted in its ordinary form, and, also, in the modified form, b

8. Um elemento finito hierarquico para analise dinamica P-adaptativa de placas espessas
The purpose of this research is to present an adaptive process of hierarchical refinement, based on the p-version parametric formulation from the Finite Element Method. The process is applied on the resolution of generalized dynamic eigenvalue problem of thick plates in the linear elasticity mode. The first leveI of approximation of the solution is obtained

10. Selective indications for the use of praziquantel in the treatment of brain cysticercosis.
The selective use of praziquantel for the treatment of brain cysticercosis in human beings is described, based upon the results of clinical tests conducted during a 2 year period. Forty patients with clinical diagnosis of cysticercosis, confirmed and documented by CT, were treated. They are divided into four groups, representative of the various forms of the

11. Development of a two-step enrichment procedure for recovery of Yersinia enterocolitica from food.
Two new enrichment media were formulated for the recovery of Yersinia enterocolitica from foods: (i) yeast extract-rose bengal broth for preenrichment at 4 or 10 degrees C; and (ii) bile-oxalate-sorbose broth, a selective enrichment incubated at 22 degrees C. Comparison of these media in a two-step enrichment procedure against cold enrichment and modified Ra

12. Instrumental conditioning of fast (20- to 50-Hz) oscillations in corticothalamic networks
Cats were instrumentally conditioned to generate grouped fast (20- to 50-Hz) oscillations in motor cortex (area 4). Over seven experimental sessions, there was a spatially selective increased generation of grouped fast oscillations in that electroencephalogram lead. This locally increased generation of fast oscillations in cortex was associated with a widesp
