13. Evolving granular systems = : Sistemas granulares evolutivos / Sistemas granulares evolutivos
In recent years there has been increasing interest in computational modeling approaches to deal with real-world data streams. Methods and algorithms have been proposed to uncover meaningful knowledge from very large (often unbounded) data sets in principle with no apparent value. This thesis introduces a framework for evolving granular modeling of uncertain

14. SOFTWARE COMPONENTS WITH SUPPORT FOR DATA STREAMS / COMPONENTES DE SOFTWARE COM SUPORTE A FLUXO DE DADOS
O desenvolvimento baseado em componentes de um tópico que tem atrasado bastante atençco nos últimos anos. Esta técnica permite a construção de sistemas de software complexos de forma rápida e estruturada. Diversos modelos de componentes já foram propostos pela indústria e pela academia. Dentro destes, aqueles que oferecem suporte da comunicação di

15. Diagnóstico do uso da água e necessidade de formação de capacidades no meio rural nas regiões administrativas do Brasil / Diagnostic of water use and need for skills training in rural areas of Brazilian administrative regions
The Brazilian territory holds the largest fresh water reserves in the world, around 12% of the total amount available. However, this is not enough to say that there is no water scarcity in this country. Most part of the streams, approximately 80%, are located in the Amazon region, which only 5% of the Brazilian population resides. Therefore, even with high w

16. Adaptação de viés indutivo de algoritmos de agrupamento de fluxos de dados / Adapting the inductive bias of data-stream clustering algorithms
Diversas áreas de pesquisa são dedicadas à compreensão de fenômenos que exigem a coleta ininterrupta de sequências de amostras, denominadas fluxos de dados. Esses fenômenos frequentemente apresentam comportamento variável e são estudados por meio de indução não supervisionada baseada em agrupamento de dados. Atualmente, o processo de agrupamento

17. Especificação de bibliotecas digitais de objetos complexos / Specification of digital libraries of digital complex objects
Digital libraries are advanced and complex information systems that store, aggregate, and manage correlated information. These systems are used by specific communities to access digital objects of interest. Due to the creation of huge collections of heterogeneous data (in terms of type and format), some of these data are organized in digital complex objects,

18. Da indenizabilidade dos terrenos marginais de rios federais nas desapropriações agrárias: estudos de caso no estado de Goiás / Inindenizabilidade of marginal land of federal rivers in the agricultural expropriations: case in the State de Goias
The Item III of art. 20 of the Federal Constitution of 1988 prescribes that belong to the Union lakes, rivers and streams in any of its land area, or bathing more than one state, that serve as boundaries with other countries, or extending or come from a foreign country, referring also to marginal lands. However, INCRA, in fulfillment of its institutional rol

19. ASPECTOS EVOLUTIVOS E DIFERENCIAÇÃO DE POPULAÇÕES DE Astyanax scabripinnis (CHARACIDAE, INCERTAE SEDIS)
The species complex Astyanax scabripinnis are composed by fish with wide geographic distribution. Their populations are often isolated in small streams, separated by thousands of years, making it a very interesting system to study evolution. The use of different markers is crucial, since they allow inferences on the identification of individuals and therefor

20. Interannual and seasonal variability of macroinvertebrates in monsoonal climate streams
The aim of this study was to assess the interannual and seasonal changes in the community composition, abundance and presence-absence of macroinvertebrates in the streams of the northwestern of Argentina. The importance of environmental variability in determining these changes was also analyzed. Macroinvertebrates were collected in eleven streams during high

21. Estructura de la comunidad de macroinvertebrados del arroyo Achiras (Córdoba, Argentina): análisis previo a la construcción de una presa
Regulation of rivers and streams modifies parameters that directly influence on the biota. In Achiras-del Gato endorheic basin has completed the construction of a midsize dam that will alter the limnological characteristics of the system and the structure of benthic communities. This study provides the first taxonomic records of macrobenthos of this lotic sy

22. A comparative structural cytogenetic study in three allopatric populations of Astyanax scabripinnis (Teleostei: Characidae)
Individual samples from five populations of the characid fish Astyanax scabripinnis (Jenyns, 1842) from the Tietê and Paranapanema river basins (Brazil) were studied. All individuals analyzed presented 50 chromosomes but three different karyotypic forms were observed. Additionally, some individuals of one karyomorph presented a macro supernumerary chromosom

23. Species composition and reproductive modes of anurans from a transitional Amazonian forest, Brazil
The aim of the present study was to describe the species composition and reproductive modes of an anuran community from a transition area between the Amazonia and Cerrado biomes. Data were collected in habitats exhibiting different degrees of anthropogenic degradation. The community (35 species) identified during the present study presented a larger number o

24. Estrutura populacional, crescimento somático e alométrico, biologia reprodutiva e estimativa do tamanho populacional de Aegla perobae Hebling &Rodrigues, 1977 do município de São Pedro, estado de São Paulo / Population structure, somatic and allometric growth, reproductive biology and population size estimation of Aegla perobae Hebling &Rodrigues, 1977 in São Pedro, São Paulo state
Aeglids are endemic to the neotropical South America. They are restricted to freshwaters, mainly occurring under rocks and fragmented leaves or buried in the sand (Burns, 1972; Rodrigues &Hebling, 1978; Swiech-Ayoub &Masunari 2001a) in lakes, rivers, streams and even rivers running into caves. The aeglids are important links in the food chain of freshwater e
