Objective: To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures. Methods: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, was conducted to search for original articles that investigated personality/temperament features of offspring of women with BD and emotional factors involved in the mother-child relationship. The electronic search was performed in the PubMed, Web of Science, and PsycINFO databases from February 2010 to February 2017. Results: Ten quantitative studies were included in the analysis: seven from the United States, two from Brazil, and one from Canada. The narrative synthesis was categorized into three dimensions: 1) reliability of instruments for prediction of future psychopathology in offspring; 2) environmental risk factors for offspring; and 3) early interventions. The findings showed impairments in the offspring’s lives, high rates of behavior and temperament problems, and psychiatric disorders. Conclusion: BD is a frequent psychiatric disorder, and the offspring of mothers with this condition are exposed to complex family relationships and psychosocial difficulties. If they are to ensure a good provision of mental health and psychosocial care to this unique population, early interventions must not neglect their contextual specificities.

Resumen El presente estudio tiene como objetivo evaluar diferentes estrategias de programación de riego en capsicum Rúbia R. el crecimiento y el rendimiento en un entorno protegido. El experimento se llevó a cabo en el Nordeste de Brasil. Se probaron cinco técnicas de programación de riego para definir la profundidad del agua (lisímetro de pesaje, ecuación de Hargreaves-Samani, evaporímetro de Piché, tensiómetro y sensor de humedad del suelo) y dos frecuencias de aplicación (F1- una vez al día y frecuencia alterna F2). Así que se configuró un experimento de diseño factorial completamente al azar en un esquema factorial de 5 x 2 y, con ocho repeticiones. Se observó que las variables diámetro del tallo e índice de área foliar de la planta estaban influenciadas por las técnicas de programación de irrigación, los tratamientos basados en los métodos de programación de Hargreaves-Samani y lisímetro de pesaje presentaron los valores más bajos. Los parámetros biométricos de los frutos fueron significativos solo para el tratamiento del Hargreaves-Samani. Se puede concluir que tanto las técnicas de planificación del riego como las frecuencias de riego influyen en el crecimiento y rendimiento del pimiento. Además, las técnicas de gestión del riego basadas en sensores de humedad del suelo proporcionaron los mayores rendimientos.

Abstract The present study aimed to evaluate different irrigation scheduling strategies on capsicum growth and yield in protected environment. The experiment was carried out at the Northeastern of Brazil. Five irrigation scheduling techniques to define water depth (weighing lysimeter, Hargreaves-Samani equation, Piché evaporimeter, tensiometer and soil moisture sensor) and two application frequencies (F1- once a day and F2-alternating frequency) were tested. A completely randomized factorial design experiment was installed in a 5 x 2 factorial scheme, with eight replicates. It was observed that the variables stem diameter and leaf area index were influenced by the irrigation scheduling techniques, and treatments based on Hargreaves-Samani and lysimeter scheduling methods led to the lowest values. Fruit biometric parameters were significantly affected only by the Hargreaves-Samani treatment. It can be concluded that both irrigation scheduling techniques and frequencies influenced capsicum growth and yield. Furthermore, irrigation management techniques based on soil sensors caused the highest yields.

Abstract Concrete is the world’s most utilized material for production of the structural elements employed in civil construction. Due to its low tensile strength and brittle nature it is reinforced with steel bars forming the reinforced concrete (RC structure). Linear elements of reinforced concrete are commonly employed in multi-story buildings, bridges, industrial sheds, among others. In this study an optimization algorithm is presented to define the amount of steel and its location within a concrete polygonal section subjected to biaxial bending with axial force, so that the amount of steel would be the minimum needed to resist the soliciting forces. Therefore, the project variables are: location, diameter and number of steel bars to be distributed within the concrete polygonal section. The sequential linear programming method is used to determine the optimized section. In this method, the non-linear problem of determining the resistance forces of the section in relation to the project variables is approximated by a sequence of linear problems, which would have its optimal point defined for each step using the Simplex method. Formulation validation is done through results of examples found in literature, and also by means of analytical solutions of simple problems, such as rectangular sections under axial force and moment in only one axis of symmetry. The results show the efficiency of the algorithm implemented in the optimized determination of the quantity and position of the bars of a given diameter in the polygonal section of reinforced concrete under biaxial bending with axial force.

RESUMO: Objetivou-se neste trabalho avaliar o efeito do cruzamento sobre as características biométricas escroto-testiculares de carneiros da raça Santa Inês e mestiços (Santa Inês x Dorper), submetidos à insulação escrotal, acompanhando o retorno dessas características aos valores previamente observados. Para isso, foram realizadas duas mensurações referentes à circunferência escrotal (CE), comprimento (C) e largura testicular (L), antes da insulação. O volume testicular (V) foi calculado pela fórmula V=2 [(r2) x π x h]. As bolsas de insulação foram fixadas ao redor do funículo espermático e escroto com fita adesiva e esparadrapo, permanecendo por sete dias. Após o período de insulação, as mensurações foram realizadas a cada sete dias, totalizando 15 mensurações durante todo o experimento. Os dados obtidos foram submetidos à análise de variância (ANOVA) para um delineamento em blocos casualizados, com dois blocos, 15 tratamentos e quatro repetições. As variáveis analisadas foram submetidas ao teste de Dunnett a 5% de probabilidade, para comparar os valores obtidos antes e após a insulação. Para a comparação entre as raças, as variáveis foram submetidas ao teste de Tukey a 5% de probabilidade. Todos os animais estudados sofreram influência significativa (P<0,05) após a insulação escrotal, porém os carneiros da raça Santa Inês retornaram aos valores anteriormente observados em um espaço de tempo mais curto do que os mestiços. Conclui-se que carneiros da raça Santa Inês apresentam maior resistência do que animais mestiços quando submetidos ao estresse térmico induzido pela insulação escrotal.

ABSTRACT: The objective of this study was to evaluate the effect of the racial crossing on scrotum-testicular biometric characteristics of four sheep Santa Ines and four crossbred (Santa Ines x Dorper) submitted to scrotal insulation, following the return of these characteristics to values previously reported. For this, two measurements were made regarding the scrotal circumference (SC), length (L) and testicular width (W) before treatments. The testicular volume (V) was calculated by the formula V=2 [(r2) x π x H]. The pouches were made with double-layer plastic, internally lined with cotton, and fixed around the spermatic funiculus and scrotum with adhesive tape and bandage remaining in this position for seven days. Measurements were made every seven days, totaling 15 measurements throughout the experiment. The data were submitted to analysis of variance (ANOVA) to a randomized block design with two blocks, 15 treatments and four replications. The variables analyzed were subjected to Dunnett test at 5% probability, to compare the values obtained before and after insulation. For comparison between the breeds, the variables were submitted to Tukey test at 5% probability. All animals studied suffered significant influence (P<0.05) after scrotal insulation, but Santa Ines returned to the values previously observed in a shorter period than the crossbred. In summary, sheep Santa Ines have a higher resistance than crossbred animals when subjected to thermal stress induced by scrotal insulation.

The present study was conducted to evaluate the toxicity of the ethanolic extract of leaves of Parkia platycephala Benth., Fabaceae, on systemic and reproductive parameters. In toxicity on the estrous cycle, four groups of not-pregnant Wistar rats received distilled water and the doses 250, 500 and 1000 mg.kg-1 of plant extract for thirty days, at the end of which they were examined as to the frequency of their phases. The systemic toxicity was assessed through the consumption of water and food and by measuring body mass. After the extract was administered, serum AST, ALT, ALP, bilirubin (total, direct and indirect), urea and creatinine were dosed. The evaluation of the organs (brain, heart, hypophysis, adrenal glands, liver, spleen, uterus and ovaries) in their macroscopic aspects, relative and absolute masses and histological structure showed that the plant extract induced a decrease of water and food consumption and of body mass. It caused an increase in the luteal phase and a decrease in the follicular phase of the estrous cycle and rose serum alkaline phosphatase levels.The data exhibit systemic and reproductive toxicity induced by plant extract in female Wistar rats.
