Abstract This paper presents the characterization of dielectric properties (dielectric permittivity and dielectric loss factor) of Tommy Atkins mango (Mangifera indica L), a fruit produced in several regions of Brazil, of great economic importance. The fruits were characterized according to their maturation index, by probe method, and identified by the yellowish tone in their bark. The results allowed correlating the dielectric characteristics of the fruit with the physicochemical transformations that occurred in the maturation process of the mango Tommy. It was also verified a greater variation in the frequencies below 1 GHz, with the maturation indicated by the dielectric signature on the fifth day after the harvest. From these results, we can observe the use of electromagnetic materials and techniques in the solution and optimization of processes in agriculture can improve the quality of products consumed or suggesting best practices to the productive sector.

RESUMO Racional: Os benefícios para a saúde associados ao consumo moderado de vinho, como etanol e compostos fenólicos, incluem mecanismos diferentes ainda pouco compreensíveis. Objetivo: Avaliar as variações da glicemia, peso e depósito de triglicrideos, colesterol e glicogênio hepático com o uso de vinho tinto. Métodos: Sessenta camundongos ApoE knockout foram divididos em três grupos de 20: Grupo do Vinho (WG), grupo do Etanol (EG) Grupo Água (WAG). Cada grupo recebeu diariamente: WG 50 ml de vinho e 50 ml de água; EG 6 ml de etanol e WAG 94 ml de água. Resultados: O WG teve aumento de peso mais elevado em comparação com os outros grupos. A concentração de triglicerídeos foi maior no WG (57%) e no grupo EG inferior (31,6%) do que no controle (p <0,01). A concentração de colesterol foi inferior no WG (23,6%) e no EG (24,5%, p<0,05). A concentração de glicogênio foi maior no WG (16%); a glicemia capilar foi maior no EG em comparação com os outros grupos, mas não demonstrou diferença estatisticamente significativa. Conclusão: Triglicerídeos ficaram aumentados no WG e o colesterol diminuiu no WAG. Os triglicerídeos podem ter aumentado devido ao alto valor calórico do vinho ou alguma propriedade desconhecida que levou ao aumento significativo da gordura subcutânea e retroperitoneal nos camundongos.

ABSTRACT Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable. Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red wine consumption. Methods: 60 ApoE knockout mice were divided into three groups of 20: Wine Group (WG), Ethanol Group (EG) and Water Group (WAG). They received daily: WG 50 ml of wine and 50 ml water; EG 6 ml ethanol and WAG 94 ml of water. All groups were followed for four months. The food intake was monitored daily, in the period from eight to ten hours and held every five days. The measurement of water intake was also made every five days. The weighing of the animals took place every ten days. Results: The WG had higher weight increase as compared to the other groups. The concentration of hepatic triglyceride was higher in WG (57%) and the EG group was lower (31.6%, p<0.01) than the control. The concentration of cholesterol was lower in the WG (23.6%), as well as EG (24.5%, p<0.05). The concentration of glycogen was higher in WG (16%) and fasting blood glucose was higher in EG compared to the other groups but not both demonstrated a statistically significant difference. Conclusion: The WG increased triglyceride and WAG decreased cholesterol. The triglyceride may be increased due to the high caloric value of wine or some unknown property that led to significant increase in subcutaneous andretroperitoneal fat in mice.

Introduction Diabetes patients can benefit significantly from early diagnosis. Thus, accurate automated screening is becoming increasingly important due to the wide spread of that disease. Previous studies in automated screening have found a maximum accuracy of 92.6%. Methods This work proposes a classification methodology based on efficient coding of the input data, which is carried out by decreasing input data redundancy using well-known ICA algorithms, such as FastICA, JADE and INFOMAX. The classifier used in the task to discriminate diabetics from non-diaibetics is the one class support vector machine. Classification tests were performed using noninvasive and invasive indicators. Results The results suggest that redundancy reduction increases one-class support vector machine performance when discriminating between diabetics and nondiabetics up to an accuracy of 98.47% while using all indicators. By using only noninvasive indicators, an accuracy of 98.28% was obtained. Conclusion The ICA feature extraction improves the performance of the classifier in the data set because it reduces the statistical dependence of the collected data, which increases the ability of the classifier to find accurate class boundaries.

Family functionality is characterized as a structuring thread for constructing adolescents' behavior. This is an exploratory, descriptive and quantitative study, whose objective was to classify adolescents' families according to the Family APGAR (Adaptation, Participation, Growth, Affection, Resolution) involving 1035 adolescents from two state schools in a state in the Brazilian northeast. The data was collected by means of the Family APGAR, during lesson time, on days and at times defined by the school management, and analyzed through descriptive statistics, using an Excel database. 73,2% of the families were described as functional, and 26,8% as dysfunctional; the dimensions adaptation and dedication were related to the adolescents' greatest satisfaction. The results generate challenges for research, for the professional insertion of the nurse into the school context, as well as for interdisciplinary work and in the adolescent care network.

La funcionalidad familiar se caracteriza como base estructurante para la construcción de comportamientos de adolescentes. Este es un estudio exploratorio descriptivo y cuantitativo, cuyo objetivo fue clasificar las familias de adolescentes de acuerdo al APGAR (Adaptation, Participation, Growth, Affection, Resolution) familiar involucrando 1.035 adolescentes de dos escuelas públicas de un estado nordestino. Los datos fueron recogidos con el apoyo del APGAR Familiar, en los horarios de las clases, en día y horas definidos por la dirección de la escuela, y analizados por medio de la estadística descriptiva a partir de banco de datos del Excel. Fueron clasificadas como funcionales 73,2% de las familias y 26,8% como disfuncionales; la mayor satisfacción de los adolescentes estuvo relacionada a las dimensiones adaptación y dedicación. Los resultados significan desafíos para investigación y para inserción profesional del enfermero en contexto escolar así como para un trabajo interdisciplinar y en red en el cuidado al adolescente.
