Objetivo: Verificar o efeito da shantala no manejo da dor em crianças hospitalizadas. Métodos: Trata-se de um estudo experimental não-controlado com abordagem quantitativa, realizado durante o período de setembro de 2018 a maio de 2019, no setor pediátrico de um hospital universitário, com crianças de zero a seis meses de idade. A análise dos dados foi feita com auxílio do software Statistical Package for the Social Science versão 21.0. Foram analisadas frequências absolutas e relativas, características epidemiológicas, clínicas e as variações de parâmetros vitais antes e após a implementação da técnica. Utilizou-se o teste de Wilcoxon para as variáveis pareadas numéricas, considerando um intervalo de confiança de 95%. Resultados: A amostra foi constituída por 50 pacientes pediátricos, com uma média de idade de 1,54±1,84 meses. Observou-se que houve relação significativa entre a shantala e o aumento da saturação de oxigênio e temperatura, e diminuição da frequência respiratória. As frequências nominais das categorias de dor expressas antes e após a execução da shantala, mostraram redução da categoria “dor leve” e considerável aumento da categoria “sem dor”. Conclusões: As evidências indicaram que a aplicação da massagem terapêutica shantala é um meio não farmacológico de grande relevância para alívio da dor e adequação dos parâmetros vitais de crianças hospitalizadas.
In this paper, we propose a modification of the linear component technique for identification of the electromagnetic waves polarization. The proposed measurement is divided in two setups and is used to obtain the amplitude of the two accessible electric field components of a plane wave. From the axial ratio and the discrete phase information obtained by trial, it is possible to determine the amplitude and phase of the electric field radiated by one or more sources. The setup is constituted by a pair of dipoles orthogonally positioned to determine these two field components. The results are obtained for two kinds of polarization: linear and circular. Good agreement was obtained between the simulated and measured results.
In this article is proposed a measurement technique to the electromagnetic polarization for completely polarized waves, using the linear component method, in order to obtain the magnitude and phase of the radiated electric field by one or many sources. Through these parameters the characteristics of the electromagnetic wave emitted by antennas, including the type and miniaturized RFID, will be defined more precisely.

In this paper, we propose a refinement of the linear component technique in identifying the polarization of electromagnetic waves. The waves propagate in free space and are considered completely polarized. The proposed measurement is divided in two setups and is used to obtain the amplitude of the two accessible electric field components of a plane wave. From the axial ratio and the discrete phase information obtained by trial, it is possible to determine the amplitude and phase of the electric field radiated by one or more sources. The setup is constituted by a pair of dipoles orthogonally positioned to determine these two field components. The results are obtained for two kinds of polarization: linear and circular. Good agreement was obtained between the simulated and measured results.
