A vector model for error propagation

A simple vector model for error propagation, which is entirely equivalent to the conventional statistical approach, is discussed. It offers considerable insight into the nature of error propagation while, at the same time, readily demonstrating the significance of uncertainty correlations. This model is well suited to the analysis of error for sets of neutron-induced reaction cross sections. 7 refs., 1 fig

The Emerging Role of miRNAs and Their Clinical Implication in Biliary Tract Cancer

Biliary tract cancers are aggressive malignancies that include gallbladder cancer and tumors of intra- and extrahepatic ducts and have a poor prognosis. Surgical resection remains the main curative therapy. Nevertheless, numerous patients experience recurrence even after radical surgery. This scenario drives the research to identify biliary tract cancer biomarkers despite the limited progress that has been made. Recently, a large number of studies have demonstrated that deregulated expression of microRNAs is closely associated with cancer development and progression. In this review, we highlight the role and importance of microRNAs in biliary tract cancers with an emphasis on utilizing circulating microRNAs as potential biomarkers. Additionally, we report several single-nucleotide polymorphisms in microRNA genes that are associated with the susceptibility of biliary tract tumors

Apoio à agropecuária sustentável e à inclusão socioprodutiva na Região Sudeste

Bibliografia: p. [230]-231Este capítulo relativo ao trabalho sobre o olhar do BNDES para a Região Sudeste do Brasil busca apontar as ações de inclusão socioprodutiva rural e urbana com base nos pontos de convergência entre a atuação da Área de Agropecuária e de Inclusão Social (AGRIS) e as diretrizes do governo federal de buscar a competitividade do setor agropecuário e a diminuição da pobreza urbana e rural no Brasil. O setor agropecuário brasileiro deve seu desenvolvimento e dinamismo, em grande parte, às atividades agropecuárias das regiões Sul, Sudeste e Centro-Oeste e, nesse cenário, a Região Sudeste é uma importante personagem, haja vista que, de acordo com os dados do Ministério da Agricultura, Pecuária e Abastecimento(Mapa), no período de 2010 a agosto de 2014, respondeu por cerca de 32% do Valor Bruto da Produção (VBP) agropecuária do país. De acordo com os principais focos de sua atuação, a AGRIS analisou, neste artigo, as ações por ela realizadas, as que estão em desenvolvimento e as em perspectiva, notadamente no financiamento de investimentos na agricultura familiar, na agropecuária em geral, na produção de alimentos, no cooperativismo de crédito e de produção e na inclusão socioprodutiva urbana.This chapter focuses on the BNDES' approach towards Brazil's Southeast Region and seeks to detail efforts towards rural and urban, social and production inclusion based on points in common between the operations of the Agriculture, Cattle-Raising and Social Inclusion Division (AGRIS) and the federal government's guidelines in seeking competition in the agricultural sector and reducing urban and rural poverty in Brazil. Brazil's agricultural sector owes its development and drive mostly to agricultural activities in the South, Southeast and Central-West Regions and in this scenario, the Southeast Region has become quite important. This is in accordance with data from the Ministry of Agriculture, Cattle-Raising and Food (MAPA), which affirms that, from 2010 to August 2014, the region was responsible for nearly 32.2% of the domestic agricultural GDP. Within the main scope of its operations, AGRIS, in this article, analyzed not only its efforts to date, but also those still underway, and those which are still a perspective. Specifically, this includes financing investments in family farming, general agriculture, food production, credit and production coops, as well as urban social and production inclusion
