1. Surface-groundwater interaction in unconfined sedimentary aquifer system in the Brazil’s tropical wet region
RESUMO Sendo as águas subterrânea e superficial importantes componentes do sistema hidrológico, a determinação da sua interação é imprescindível para a gestão eficiente dos recursos hídricos por prognosticar as consequências de interferências, seja devido ao crescimento da demanda, seja devido às mudanças climáticas. Todavia, estudos cientí

2. Performance evaluation of flow duration curves regionalization methods
RESUMO Este estudo teve como principal perspectiva avaliar as respostas dos métodos do Valores Característicos e da Curva Exponencial, alternativas disponíveis para a regionalização de curvas de permanência de vazões. O trabalho avaliou, adicionalmente, o emprego de indicadores regionais de vazão para a estimativa de vazões de referência associada

3. Interferential electrical stimulation improves peripheral vasodilatation in healthy individuals
BACKGROUND: Interferential electrical stimulation (IES), which may be linked to greater penetration of deep tissue, may restore blood flow by sympathetic nervous modulation; however, studies have found no association between the frequency and duration of the application and blood flow. We hypothesized that 30 min of IES applied to the ganglion stellate reg

4. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

5. Regionalização de potencial hidrelétrico com escassez de dados : aplicação Moçambique
Hydroelectricity (hydropower) is one branch of water resources engineering, which uses water (river flows) producing electricity. A hydroelectric undertaking, besides providing electricity and its comfort, it also allows the establishment of other productive activities, which provides a good economic and social development of the population (social responsab

6. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

7. Sustentabilidade de barragens e o planejamento de hidreletricas na Bolivia / Sustainability of dams and hydroelectric plants planning in Bolivia
The construction of dams has been one important option that was used by many countries in order to reach the development. With elapsing of the years the dams has evidence that produce many benefits but also impacts, that s why must be a balance in the choice and determination of the new projects in function of the needs and always with the goal of reach the

8. Analysis of grant criteria based on minimum flow and flow according to duration curve for water consumptive uses. / Análise dos critérios de outorga de direito de usos consuntivos dos recursos hídricos baseados em vazões mínimas e em vazões de permanência.
Through these ten years of the Water Resources Brazilian Policy, some difficulties have been presented to the water resources management in so far as the management instruments has becoming solid, mainly to the grant of right for using water resources. A problem of those refers to the low water availability in several water basins, where the total water dema

9. Experimental hydrographs of wetlands in Jacupiranguinhas river microbasins in the Baixo Ribeira do Iguape Valley, SP / Hidrogramas experimentais de área alagada da micro bacia do rio Jacupiranguinha, Baixo Ribeira do Iguape, SP
It is very important to improve our knowledge about the floodplains, which have been proved by studies, since these areas are vital to the maintenance and preservation of the quality of waters and the fluvial ecosystem. This fact, associated with the importance of the wetlands-river system, makes its investigation and preservation to be considered number one

10. Indicadores de vazões mínimas de referência em sub bacias do Rio Miranda
Devido ao crescimento populacional e econômico, Mato Grosso do Sul é uma das regiões de expansão da fronteira agrícola no país e por isso pressiona os recursos hídricos, que aliado à ocorrência de estiagem podem causar degradação do meio ambiente. Um requisito para possibilitar a continuidade das funções oferecidas pela água, é a manutenção

11. Extracellular ions and excitation-contraction coupling in frog twitch muscle fibres.
Intracellular calcium transients were recorded from voltage-clamped frog twitch muscle fibres using Arsenazo III. The possible role of extracellular ions in excitation-contraction (e.-c.) coupling was examined using ion substitutions and blocking drugs in the bathing medium. Parameters measured included the Arsenazo response size to a standard depolarizing p

12. Mechanochemical coupling in muscle: attempts to measure simultaneously shortening and ATPase rates in myofibrils.
We studied the ATPase of shortening myofibrils at 4 degrees C by the rapid flow quench method. The progress curve has three phases: a P(i) burst, a fast linear phase kF of duration tB, and a deceleration to a slow kS. We propose that kF is the ATPase of myofibrils shortening under zero external load; at tB shortening and ATPase rates are reduced by passive r
