Resumo Objetivos: identificar variáveis associadas à presença de acompanhante na sala de parto e sua associação com o aleitamento materno (AM) na primeira hora de vida. Métodos: análise transversal de dados provenientes de um estudo de coorte (n=344). Para investigação dos fatores associados entre a presença de companhia durante o parto e o AM na primeira hora foram realizadas análises de regressão de Poisson, considerando p<0,05 como nível de significância estatística. Resultados: 93,9% das parturientes tiveram acompanhante na sala de parto, não sendo encontrada associação entre características socioeconômicas, obstétricas e neonatais do binômio mãe-filho e esta presença. Em análise univariada, a ausência de acompanhante reduziu a frequência de AM na primeira hora (RP=0,64; IC95%=0,42-0,96), resultado que não se confirmou nas análises ajustadas (RP=0,79; IC95%=0,54-1,15). Secundariamente, identificou-se que o Apgar no quinto minuto associou-se com AM na primeira hora (RP=1,27; IC95%=1,14-1,40) independentemente dos demais fatores. Conclusões: a maioria das mulheres da coorte contou com acompanhante na sala de parto, sem diferenças segundo variáveis socioeconômicas, obstétricas e neonatais. A frequência de AM na primeira hora também foi alta e menor na ausência de acompanhante, contudo, essa associação não se mostrou independente de outros fatores.

Abstract Objectives: to identify variables associated with the presence of a companion in the delivery room and its association with breastfeeding (BF) in the first hour of life. Methods: cross-sectional analysis of data from a cohort study (n=344). To investigate the factors associated with the presence of a companion during childbirth and breastfeeding in the first hour; we performed Poisson regression analyses, considering p<0.05 as the level of statistical significance. Results: 93.9% of the pregnant women had a companion in the delivery room, and no association was found between socioeconomic, obstetric and neonatal characteristics of the mother-child binomial and the presence of a companion. In a univariate analysis, the absence of a companion reduced the frequency of breastfeeding in the first hour (PR=0.64; CI95%=0.42-0.96), a result that was not confirmed in the adjusted analyses (PR=0.79; CI95%=0.54-1.15). Secondly, it was identified that the five minutes Apgar score was associated with first hour breastfeeding (PR=1.27; CI95%=1.14-1.40) regardless of the other factors. Conclusions: most women in the cohort had a companion in the delivery room, with no differences according to socioeconomic, obstetric and neonatal variables. The frequency of first hour breastfeeding was high; however, it was lower in the absence of a companion but this association was not independent of other factors.

Although analytical techniques to assess the degradation of transformer insulation systems are well established, it is essential to develop fast and effective methodologies for monitoring the quality of power transformer insulating fluid. The objective of this work was to develop a fast, simple, and environmentally friendly method to evaluate and monitor the quality of insulating vegetable oil (IVO) from transformers, using multivariate control chart and infrared spectroscopy (FTIR). For the development of the method, IVO samples were subjected to electrical and thermal stress, as well as to contact with insulating paper and copper, to simulate the internal environment of a transformer before and after energizing. Control chart based on principal component analysis was developed to monitor insulating vegetable oil quality. It was possible to identify oil samples with oxidation levels that were outside the acceptable quality standards for insulating fluid in transformers. The results demonstrated the potential of FTIR spectroscopy and control charts as fast and simple tools for monitoring the quality of insulating fluids, enabling the identification of oil samples that fail to comply with regulation standards for insulating fluids, assisting in the implementation of maintenance programs for power transformers.

RESUMO O Brasil é o terceiro maior produtor de frutas do mundo, porém muitas fruteiras nativas continuam subexploradas, como ocorre com a mangabeira (Hancornia speciosa Gomes). Pouco se conhece sobre os aspectos gerais da espécie em seus ambientes de ocorrência natural. Desta forma, objetivou-se caracterizar a morfologia da planta e do fruto de mangabeiras silvestres selecionadas em áreas de ocorrência natural da espécie, em vegetação de transição entre o Cerrado e a Restinga. O experimento foi realizado no município de Morros-Maranhão, nos povoados Patizal, Recanto e Recurso, caracterizados por extensas áreas de vegetação de transição: Cerrado e Restinga, com ocorrência natural de mangabeira. Nos três povoados, selecionaram-se 45 mangabeiras-matrizes, das quais se mensuraram a altura total, altura do fuste, diâmetro do caule, volume de copa, número de ramos principais e secundários, e número de frutos. Coletaram-se 20 frutos por matriz e determinaram-se a massa, comprimento e diâmetro dos frutos, massa da polpa mais casca, rendimento de polpa, número e massa de sementes. Houve elevado grau de variabilidade para todas as variáveis estudadas, exceto para o rendimento de polpa (média = 86,69%, mínimo = 76,75% e máximo = 91,11%; CV = 3,51%). Há correlação positiva significativa de alta magnitude entre as variáveis massa do fruto e massa da polpa mais casca com o número de sementes (r=0,01; ?=0,78 e ?=0,74, respectivamente).

ABSTRACT Brazil is the third largest fruit producer in the world, but many native fruits remain underexploited, as is the case for mangabeira (Hancornia speciosa Gomes). Little is known about general aspects of this species in its naturally occurring environment. Thus, this study aimed to characterize plant and fruit morphologies from native mangabeira selections in the Savannah-Restinga vegetation transition zone. The experiment was carried out in Patizal, Recanto and Recurso villages located in the Morros municipality, Maranhão State, dominated by extensive Savannah-Restinga vegetation transition zone with naturally occurring mangabeiras. Forty five mangabeira trees were randomly chosen from native selections in the three villages. Data collected were plant height, stem height, stem diameter, canopy volume, number of main and secondary branches and number of fruits. Twenty fruits were collected per plant to determine the mass, length and diameter, pulp and skin mass, pulp yield, seed number and seed mass. There was a high degree of variability for all assessed variables except for the pulp yield (average = 86.69%, minimum = 76.75% and maximum = 91.11%; CV= 3.51%). Significant and positive high magnitude correlations were noted among the variables of fruit mass and pulp mass plus skin with seed number (r=0,01; ?=0,78 e ?=0,74, respectively).
