13. In vivo fluctuation of Tax, Foxp3, CTLA-4, and GITR mRNA expression in CD4+CD25+ T cells of patients with human T-lymphotropic virus type 1-associated myelopathy
HTLV-1 Tax expression exerts an inhibitory effect on the Foxp3 transcription factor in CD4+CD25+ T-regulatory cells (Treg). For a better understanding of the role of Tax mRNA in the gene expression of cellular markers we measured Tax, Foxp3, CTLA-4, GITR, TGF-β, and IL-10 mRNA in Treg cells of 50 patients with human T-lymphotropic virus type 1 (HTLV-1)-asso

15. Análise faunística e flutuação populacional de cigarrinhas (Hemiptera: Cicadellidae) potenciais vetoras de Xylella fastidiosa em pomares de ameixeira nos estados do Rio Grande do Sul e São Paulo, Brasil / Faunistic analysis and seasonal fluctuation of sharpshooters (Hemiptera:Cicadellidae) that are potential vectors of Xylella fastidiosa in plum orchards in Rio Grande do Sul and São Paulo states, Brazil
The plum leaf scald (PLF) is a major threat for plum production in Brazil. PLF is caused by the bacteria Xylella fastidiosa which is transmitted by sharpshooter leafhoppers (Hemiptera: Cicadellidae, Cicadellinae). In this investigation, we surveyed the Cicadellinae species associated with plum orchards located in Rio Grande do Sul (RS) and São Paulo (SP) st

16. Clustering analysis of the data of DFA profiles of eletric induction in oil wells / Análise de agrupamentos dos dados de DFA oriundos de perfis elétricos de indução de poços de petróleo
The main objective of this study is to apply recently developed methods of physical-statistic to time series analysis, particularly in electrical inductions profiles of oil wells data, to study the petrophysical similarity of those wells in a spatial distribution. For this, we used the DFA method in order to know if we can or not use this technique to charac

17. Transmission of prices and volatility in the marketing of pork / Transmissão de preços e da volatilidade na comercialização da carne suína
The pork chain, despite showing significant technical improvement and competitiveness, is still one of the most volatile sectors of Brazilian agribusiness, and marketing and price fluctuation is one of the main barriers for its development. Accordingly, the present study aimed to analyze the price ratios and volatility among production agents and major meat

18. Accounting earnings properties and determinants of earnings response coefficient in Brazil / Propriedades do lucro contábil e determinantes do coeficiente de resposta ao lucro no Brasil
A fundamental issue at the interface of economics, finance, and accounting involves the relation between a firms reported earnings and its stock returns. The lack of research in this field using Brazilian data and the limitations of previous research in terms of time-series data (small length available) motivates the present research. In addition, the practi

19. Determinação da recarga profunda na bacia-piloto do Ribeirão da Onça em zona de afloramento do Sistema Aqüífero Guarani a partir de balanço hídrico em zona saturada / Determination of the deep recharge in the Ribeirão da Onça pilot basin in the outcrop zone of the Guarani Aquifer System through water balance in the saturated zone
Main objective of this work was the determination of the deep recharge in the Ribeirão da Onça basin through water balance in the soil saturated zone. This basin is located in the outcrop zone of the Guarani Aquifer System (GAS) in the São Paulo State - Brazil and is covered by cenozoic sedimentary soil. The water balance model involved the determination

20. Ocorrência e bionomia de Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) e seu inimigo natural Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) em plantas de Eucalyptus globulus / Occurrence and bionomy of Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) and its natural enemy Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae) in plants of Eucalyptus globulus.
Species of the genus Eucalyptus hosting several species of insects of the family Psyllidae. Among them, the specie Ctenarytaina eucalypti (Maskell) (Hemiptera: Psyllidae) is considered the most harmful, causing damage to culture wherever it has been introduced. To control these hemiptera phytophage, treatment with insecticides proved to be costly and unsusta

21. Fatoração QR como ferramenta para a determinação de poços principais em redes de monitoramento de aqüíferos freáticos
Monitoring networks of piezometric motion are increasingly used for evaluation and management of aquifers. A pivoted version of the QR factorization was used in four networks, with the purpose of determining principal wells. One network is located at river Jardim watershed, at the east portion of Distrito Federal, Brazil, and the other three are located in s
