1. Fishes community composition and patterns of species distribution in Neotropical streams
Resumo: A ictiofauna de riachos na região Neotropical ainda não é totalmente conhecida. Este estudo objetiva investigar a composição da ictiofauna de seis riachos da sub-bacia do rio Ijuí, estado do Rio Grande do Sul, inseridos na bacia do rio Uruguai, de forma a contribuir no conhecimento da riqueza e distribuição de espécies de peixes no sul do Br

2. GROUPNESS RACIAL E FLUTUAÇÕES ATITUDINAIS DE PARDOS ENTRE FRONTEIRAS SIMBÓLICAS E SOCIAIS
Neste artigo, examinamos a permeabilidade das fronteiras simbólicas raciais a partir da identificação e análise de atitudes referentes: (1) ao preconceito; (2) à mistura racial e (3) ao apoio às políticas de cotas. Mais especificamente, exploramos a hipótese de que as opiniões posicionais dos pardos, em virtude da sua localização intermediária no

3. Bridging a historical gap: can changes in perceptions of law enforcement and social deterrence accelerate the prevention of drunk driving in low and middle-income countries?
Objectives: The dangers of driving while under the influence of alcohol/drugs (DWI) have been well established. Many countries have successfully reduced the incidence of DWI through effective law enforcement. We aim to explore the links between how law enforcement is perceived in cultures with different socioeconomic indicators. Our hypothesis is that socia

4. Hydraulic architecture of lianas in a semiarid climate: efficiency or safety?
Xylem anatomical traits can provide insights regarding the mechanisms affecting the distribution of vascular plants across environmental gradients. In this study, we aimed to investigate the hypothesis that lianas occurring in semiarid environments have characteristics that maximize the xylem resistance to tension-induced cavitation along the root-stem-branc

5. Reflection of cardinal functions / Reflexão de funções cardinais
This work investigates problems about reflection of cardinal functions, using techniques such as elementary submodels and PCF Theory. We show that the Lindelöf degree reflects all the strongly inaccessible cardinals and that a example of a space in which the same cardinal function does not reflect a weakly inaccessible cardinal requires \"0# exists\".

6. Defense-related emotions in humans
The study of the role of serotonin in anxiety has led to the view that this neurotransmitter enhances anxiety, but inhibits panic. Validation of this hypothesis has been made using two experimental procedures that increase anxiety in human volunteers. One is classical conditioning of the skin electrical conductance response, which is assumed to represent anx

7. Os gestos na interação de crianças ouvintes e surdas: as possibilidades de um contexto bilíngue.
This research regards an observational, qualitative study, which involves 08 (eight) hearing children and 03 (three) deaf children, aged between 7;7 and 11;10, in spontaneous daily interactions within a 3rd year Elementary School classroom in an inclusive private school, in Arapiraca, Alagoas. Our main goal is to identify the strategies adopted by hearing ch

8. O choque entre dois mundos o contato entre o índio e o branco na colonização do Vale do Itajaí: um estudo sobre a interpretação do imigrante europeu a respeito dos Xokleng 1850 - 1914
The goal of the present work is the interpretation of the way European immigrants saw the Indians in the Itajaí Valley, from the foundation of the Blumenau colony in 1850, up to their pacification through the creation of Indian reservations in 1914. This will be done through the analysis of the abundant primary documental sources in that region, which have

9. Environmental constraints structuring fish assemblages in the river Paraíba do Sul watershed: Land use condition, habitat and physico-chemical water quality. / Condicionantes ambientais estruturadoras das assembléias de peixes da bacia do rio Paraíba do Sul: Condição do uso da terra, do habitat físico e qualidade físico-química da água.
Structure and dynamic of the Paraíba do Sul fish assemblages and their relationship with environmental constraints in both regional (e.g. altitude, area of drainage, flow and land use) and local (microhabitat and physico-chemical) scales were studied. A fish sampling programme was carried out in the whole extension of the main channel (1100 km) and in the s

10. Distribuição longitudinal de adultos de Odonata em riachos no Cerrado: uma hipótese ecofisiológica / Longitudinal distribution of adult Odonata in Cerrado streams: an ecophysiologic hypothesis
The longitudinal distribution of adult Odonata was examined in streams of different channel width in the Pindaíba River Basin, in the municipalities of Barra do Garças and Nova Xavantina. The general purpose was to evaluate the existence of environmental gradients that affect the longitudinal distribution of Odonata, and to establish testable predictions t

11. Simulação de escoamentos gás-sólido reativos em leitos fluidizados circulantes / Simulation of reactive gas-solid flows in circulating fluidized beds
Circulating fluidized bed reactors are widely used in large scale applications such as catalytic cracking of petrol and coal combustion. Development and design in those areas are strongly based on demonstration plants, at extremely high costs. In this context, treatments applying computational fluid mechanics assume considerable relevance. The complex gas-so

12. Communication in Scene Complexity in Times of Creation / Comunicação em cena - complexidade em tempos de criação
Communication in Scene Complexity in Times of Creation is a theoretical/practical investigation that studies the movements of body and its process of creation starting from means of communication in which it emerges. The body, here understood as an intertwining between nature and culture, creates cultural texts that transforms itself over time, both by diver
