25. Reproductive biology of Sciades herzbergii (Siluriformes: Ariidae) in a tropical estuary in Brazil
The present study investigated the reproductive biology of Sciades herzbergii in the Paraíba do Norte River Estuary, Brazil. We aimed to characterize the reproduction of the species with respect to sex ratio, spawning season, condition factor and length at first maturity. Specimens were captured between August 2009 and July 2010 in a stretch of the main cha

26. A estrutura do canal de comercialização de maçãs e as relações estabelecidas entre seus players - o caso da região de Vacaria (RS)
Aspects involved in the global discussion regarding hunger and extreme poverty reduction must be addressed using a framework that considers the behavior of food producers and consequently their conditions in the field. When dealing with such a sample, understanding the structure of distribution channels is mandatory for the comprehension of economic power´s

27. Scorpionism in Central America, with special reference to the case of Panama
Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Cost

28. Composition, species richness and patterns of nycthemeral vertical distribution of planktonic cladocereans in a black water Amazonian lake
The aim of this study was to identify patterns of vertical distribution of planktonic cladocerean populations throughout the diel cycle, during the low and high water periods, and its ecological implications for a black water Amazonian lake. Tupé Lake is a black water lake located near the Brazilian city of Manaus. A channel links the lake with the Negro Ri

29. Editorial
Harbor terminals and urban sewage effluents affect the composition and distribution of epibenthic organisms. In this study, we hypothesized that the benthic community structure at the Vitoria Harbor changes spatially in a ~3 km scale, and that these changes are associated with environmental gradients resulting from point-source sewage and differences in the

30. Effect of particle clusters on turbulence modulations in liquid flow laden with fine solid particles
Studies on particle distributions and interactions between the particles and the liquid turbulence are extremely significant and can help to improve efficiency of industrial processes and final product quality. In this paper, the particle distribution and the particle - turbulence interaction in the solid - liquid flow were investigated in detail by a numeri

31. Macrobenthic community structure in a Brazilian chocked lagoon system under environmental stress
Saquarema-Jaconé lagoonal system (SJLS) comprises a sequence of five interconnected shallow brackish lagoons with access to the sea by a single permanent tidal channel. It is a eutrophic system, receiving constant input of organic load from its urbanized catchments. The relationship between several environmental variables and the spatial-temporal distributi

32. Dilute-phase pneumatic conveying of polystyrene particles: pressure drop curve and particle distribution over the pipe cross-section
During the pneumatic conveying of plastic pellets, it has been observed that materials with similar physical characteristics may develop a substantial difference in pressure drop. In this work, the pressure drop in a particle-laden 2.7 meter long horizontal channel with circular cross-section is presented from an experimental perspective. Experiments are car

33. Avaliação da produção de sedimento na bacia hidrográfica do rio Potengi através do modelo SWAT
Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the ap

34. Consequências da barragem eclusa do Canal São Gonçalo para a ictiofauna do sistema Patos-Mirim / Consequences of the São Gonçalo channel s dam-lock to the ichthyofauna of the Patos-Mirim system
The present study aimed to investigate the consequences of the São Gonçalo channel dam-lock in the structure of the marine, estuarine and freshwater fish assemblies that inhabit the Patos-Mirim lagoon system. The study area was the São Gonçalo channel that connects the Patos Lagoon with the Mirim Lagoon. Sampling took place monthly during years 2005 (12

35. Distribution strategies for the base of the pyramid : an exploratory study in Brazil
Access has been one of the main difficulties companies have faced in emerging markets (PRAHALAD, 2005). The capillarity of the market, the existence of small, not professionalized and sometimes informal retailers, the lack of infrastructure and high transportation costs are some of the distribution challenges companies face in poorer regions. The literature
