Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.53B005
Abstract:

This paper presents a comparative study on Magnetic-Dispersion based Energy Harvesting Systems (MD-EHS) on electrical conductors that supply power for a three-phase AC motor. It introduces two MD-EHS which are based on magnetic cores of different material, named, nanocrystalline, ferrite and iron powder. The first one consists of harvesting energy from magnetic flux through three symmetrical magnetic cores installed on each power conductors of a three-phase AC motor. The second one consists of a single magnetic core for harvesting energy from magnetic flux of only one of these conductors. Both ones have an AC/DC converter and a variable resistor based load. Experimental results have agreed with the theoretical analysis and show that the first proposed MD-EHS is capable of supplying 14 times more energy than the second MD-EHS, considering nanocrystalline cores and phase current of 3 A, and 7.5 times more energy, considering ferrite cores and phase current of 9 A. Such energy can be applied to various low-power devices, especially in wireless sensor network.

Abstract: OBJETIVO: Descrever a evolu o da assistência materno-infantil, com base nas informa es extraídas de dois inquéritos domiciliares realizados nos anos de 1984/85 e de 1995/96, na cidade de S o Paulo, SP. MéTODOS: Foram estudadas amostras probabilísticas da popula o entre zero e 59 meses de idade: 1.016 crian as em 1984/85 e 1.280 crian as em 1995/96. Três componentes da assistência materno-infantil foram investigados: assistência pré-natal, assistência ao parto e ao recém-nascido e assistência de puericultura. RESULTADOS: Aspectos favoráveis da evolu o da assistência materno-infantil na cidade de S o Paulo foram a manuten o da cobertura universal da assistência hospitalar ao parto, a expans o substancial do alojamento conjunto m e-filho na maternidade, o aumento no número de consultas de puericultura no primeiro ano de vida e, sobretudo, a universaliza o da cobertura das vacinas BCG, tríplice e anti-sarampo. Aspectos desfavoráveis foram o progresso muito modesto e claramente insuficiente da assistência pré-natal, a manuten o de quase 50% de cesarianas e a n o expans o da puericultura após o primeiro ano de vida. CONCLUS ES: Estimativas sobre a evolu o da assistência materno-infantil no conjunto das áreas urbanas do País em período semelhante confirma e acentua o desempenho insatisfatório da assistência pré-natal na cidade de S o Paulo. Compara es favoráveis a S o Paulo s o registradas apenas quanto a cobertura vacinal. A influência que mudan as na assistência materno-infantil podem ter exercido sobre a evolu o de diferentes indicadores do estado de saúde das crian as da cidade é examinada em artigos subseqüentes.
