Assessment of water resources usisng hydrological modelling: applying VISUAL BALAN v2.0 code to a river basin in Serra da Estrela(Central Portugal)

Numerical models are needed to evaluate complex hydrological systems. VISUAL BALAN v2.0 is a lumped hydrological code which performs daily water balances in the soil, the unsaturated zone and the aquifer requiring a small number of parameters. VISUAL BALAN has been used to model the river Zêzere catchment upstream of Manteigas (Serra da Estrela, Central Portugal), in order to assess its water resources. Modelling started with the definition of sub-basins based on hydrogeomorphological units. Then, daily temperature and precipitation data from Manteigas meteorological station were extrapolated to each sub-basin considering vertical gradients. Finally, modelling with VISUAL BALAN was performed in four stages: (i) physical characterisation of each sub-basin; (ii) preliminary calculations of the daily water balance; (iii) model calibration by means of flow measurements in the river Zêzere; (iv) result analysis. This basin exhibits complex patterns in hydrometeorological variables such as rainfall and temperature. Several sub-basins have been defined in order to account for the spatial variability in hydrometeorological and geomorphological variables. The model reproduces observed flowrates while its results are coherent with the conclusions of previous studies in similar basins.info:eu-repo/semantics/publishedVersio

Uso da acupressão para minimizar desconfortos na gestação

Objetivo: Descrever respostas emitidas por gestantes, quanto à melhora dos desconfortos gravídicos após aplicação da técnica da acupressão.Método: Estudo qualitativo e descritivo desenvolvido com 15 gestantes entre novembro de 2013 e fevereiro de 2014 em uma Unidade Básica de Saúde de Natal-RN, Brasil. A coleta de dados ocorreu por meio de entrevista não estruturada, e os depoimentos, depois de transcritos e tratados de acordo com a proposta operativa de Minayo, foram lidos criteriosamente, comparados entre si e organizados em dois grupos.Resultados: As categorias suscitadas foram: Repercussões positivas da acupressão e Recomendações do uso da acupressão. Segundo as gestantes, os desconfortos da gravidez como câimbras, cansaço nos membros inferiores, lombalgia e cefaleia diminuíram com o uso da acupressão.Conclusões: Baseado nos resultados obtidos, a acupressão deve ser introduzida pela(o) enfermeira(o) em consultas pré-natais como recurso terapêutico em prol da obtenção do bem-estar da gestante.Palavras-chave: Enfermagem obstétrica. Cuidado pré-natal. Acupressão. Humanização da assistência
