Prevalência da infecção pelo vírus da hepatite C em comunidades remanescentes de quilombos no Brasil Central
In order to determine the prevalence of hepatitis C virus (HCV) infection in quilombo remnant communities in Central Brazil, 1,007 subjects were interviewed in all 12 communities existing in Mato Grosso do Sul State, Central Brazil. Blood samples were collected and sera were tested for anti-HCV by enzyme-linked immunosorbent assay. Positive samples were retested for confirmation using a line immunoassay and were also subjected to HCV RNA detection. The prevalence of HCV infection was 0.2%. This finding shows a low prevalence of HCV infection in quilombo remnant communities in Central Brazil.Com objetivo de estimar a prevalência da infecção pelo vírus da hepatite C (HCV) em comunidades remanescentes de quilombos no Brasil Central, 1.007 indivíduos foram entrevistados nas 12 comunidades quilombolas existentes no Estado de Mato Grosso do Sul, Brasil Central. Amostras sanguíneas foram coletadas e os soros testados para anti-HCV pelo ensaio imunoenzimático. As amostras positivas foram testadas pelo ensaio confirmatório "line immunoassay" e também submetidas à detecção do RNA-HCV. A prevalência da infecção pelo HCV foi de 0,2%. Este achado mostra uma baixa prevalência da infecção pelo HCV em comunidades remanescentes de quilombos no Brasil Central
Integrated approach of hydrogeomorphology and GIS mapping to the evaluation of ground water resources: an example from the hydromineral system of Caldas da Cavaca, NW Portugal.
Understanding the role of geomorphology is essential to accurately assess hydrogeological systems and groundwater resources. Hard-rock watersheds provide a source of valuable water resources. They commonly exhibit complex geological bedrock and morphological features as well as distinctive gradients in rainfall and temperature. A comprehensive evaluation and integrated gro undwater resources study has been carried out for Caldas da Cavaca hydromineral system in NW Portugal, using hydrogeomorphology and GIS mapping techniques. Thematic maps were prepared from satellite imagery, topographical and geological mapping and other hydrogeological field data. These maps were converted to GIS format a nd then integrated using GIS software with the purpose of elaborating a hydrogeomorphological map intended to delineate the infiltration potential areas for the study region. Finally, this study highlights the importance of hydrogeomorphological cartography and groundwater GIS mapping as useful tools to support hydrogeological surveys, as well as for decision-making in the scope of management plans respecting to land and water resources and groundwater sustainability

Marian: Fast Neural Machine Translation in C++
We present Marian, an efficient and self-contained Neural Machine Translation
framework with an integrated automatic differentiation engine based on dynamic
computation graphs. Marian is written entirely in C++. We describe the design
of the encoder-decoder framework and demonstrate that a research-friendly
toolkit can achieve high training and translation speed.Comment: Demonstration pape
