1. Recarga de aquífero em Floresta Estacional Decidual nativa, Parque Estadual do Turvo (RS)
RESUMO Considerando a importância das florestas na retenção das águas oriundas da precipitação pluviométrica e a sua função estratégica na recarga de aquíferos, este estudo teve por objetivo estimar a recarga direta e natural do aquífero raso da zona de alteração dos basaltos da Formação Serra Geral, subjacente à Floresta Estacional Decidual

2. Recharge contribution to the Guarani Aquifer System estimated from the water balance method in a representative watershed
A contribuição da recarga para sistemas regionais de fluxo de água subterrânea é uma informação essencial requerida para estabelecer o gerenciamento sustentável de recursos hídricos. O objetivo deste trabalho foi determinar o escoamento de água subterrânea na Bacia do Ribeirão da Onça usando um modelo de balanço hídrico da zona saturada do sub

3. MONITORING THE FLUCTUATION OF THE WATER TABLE IN UNCONFINED AQUIFERS FOR EVALUATION OF THE POTENTIAL RECHARGE IN OUTCROP ZONE OF THE GUARANI AQUIFER SYSTEM IN CACEQUI - RS/BR / MONITORAMENTO DA FLUTUAÇÃO DOS NÍVEIS DE ÁGUA EM AQUÍFEROS FREÁTICOS PARA AVALIAÇÃO DO POTENCIAL DE RECARGA EM ÁREA DE AFLORAMENTO DO SISTEMA AQUÍFERO GUARANI EM CACEQUI - RS
This research aimed to estimate the recharge and groundwater water table fluctuation in areas with withdrawals of groundwater and surface water related to the variation of groundwater levels and rainfall events. The two areas of study was inserted within the Cacequi Municipality, which is located in the Rio Grande do Sul state, southwestern Brazil, in the Gu

4. Recarga de aquíferos superficiais na região do Alto Rio Grande-MG
As nascentes são afloramentos dos aquíferos superficiais, e o ciclo da água neste ambiente passa pela recarga que é definida, de maneira geral, como a quantidade de água que é acrescentada ao aquífero, podendo ocorrer localmente a partir da infiltração das águas das chuvas. Neste trabalho, apresenta-se o método de flutuação das superfícies livr

5. RECARGA E FLUTUAÇÃO DO NÍVEL DA ÁGUA SUBTERRÂNEA EM SUBBACIAS COM FLORESTA E CAMPO NATIVO / RECHARGE AND FLUCTUTION LEVEL OF GROUNDWATER IN SUB-BASINS WITH FOREST AND NATIVE FIELD
A presente pesquisa busca contribuir com as investigações voltadas ao conhecimento do comportamento das águas subterrâneas. Com finalidade de determinar a estimativa de recarga subterrânea e análise da flutuação do nível da água em relação a eventos de precipitação pluviométrica. Atendendo aos objetivos a investigação se apóia nos referenci

6. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

7. 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

8. A Recombinant Measles Vaccine Virus Expressing Wild-Type Glycoproteins: Consequences for Viral Spread and Cell Tropism
Wild-type, lymphotropic strains of measles virus (MV) and tissue culture-adapted MV vaccine strains possess different cell tropisms. This observation has led to attempts to identify the viral receptors and to characterize the functions of the MV glycoproteins. We have functionally analyzed the interactions of MV hemagglutinin (H) and fusion (F) proteins of v

9. Induction of maturation of human blood dendritic cell precursors by measles virus is associated with immunosuppression
As well as inducing a protective immune response against reinfection, acute measles is associated with a marked suppression of immune functions against superinfecting agents and recall antigens, and this association is the major cause of the current high morbidity and mortality rate associated with measles virus (MV) infections. Dendritic cells (DCs) are ant

10. Receptor usage and differential downregulation of CD46 by measles virus wild-type and vaccine strains.
Recently, two cell surface molecules, CD46 and moesin, have been found to be functionally associated with measles virus (MV) infectivity of cells. We investigated the receptor usage of MV wild-type, subacute sclerosing panencephalitis, and vaccine strains and their effect on the down-regulation of CD46 after infection. We found that the infection of human ce

11. Mutations in the Putative HR-C Region of the Measles Virus F2 Glycoprotein Modulate Syncytium Formation
The fusion (F) glycoproteins of measles virus strains Edmonston (MV-Edm) and wtF (MV-wtF) confer distinct cytopathic effects and strengths of hemagglutinin (H) interaction on a recombinant MV-Edm virus. They differ in just two amino acids, V94 and V101 in F-Edm versus M94 and F101 in F-wtF, both of which lie in the relatively uncharacterized F2 domain. By co

12. Global Effects on Gene Expression in Fission Yeast by Silencing and RNA Interference Machineries†
Histone modifications influence gene expression in complex ways. The RNA interference (RNAi) machinery can repress transcription by recruiting histone-modifying enzymes to chromatin, although it is not clear whether this is a general mechanism for gene silencing or whether it requires repeated sequences such as long terminal repeats (LTRs). We analyzed the g
