1. A Genetic Algorithm for Pointwise Source Reconstruction by the Method of Fundamental Solutions
ABSTRACT Inverse source reconstruction problems offer great potential for applications of interest to engineering, such as the identification of polluting sources, and to medicine, such as electroencephalography, to cite at least two relevant examples. From a mathematical point of view, the identification of a concentrated source (intensity and location) cor

2. Carcinoma prostático com metástase para seios frontal e cavernoso: relato de caso
Abstract One of the major problems affecting potatoes quality on stored is the susceptibility to enzymatic browning, which occurs mainly after wounds during the harvest, at postharvest handling and by aging, leading to the development of dark color compounds. Enzymatic browning is associated with the action of polyphenoloxidases (PPO) and peroxidases (POD),

4. Correlação entre qualidade da água e ocorrência de diarreia e hepatite A no Distrito Federal/Brasil
RESUMO O abastecimento público de água de maneira segura e eficiente ainda é um desafio no Brasil. Isso pode levar a um aumento na incidência de agravos como Doença Diarreica Aguda (DDA) e hepatite A. O objetivo deste trabalho foi associar a qualidade da água distribuída e a ocorrência de DDA e hepatite A no Distrito Federal (DF) (Brasil) entre 2012

5. Association of organized physical activity and levels of cardiorespiratory fitness with indicators of mental health in children
Abstract Aim: To verify the associations between organized physical activity out of school (PA) and cardiorespiratory fitness (CRF) with indicators of mental health in children. Methods: This is a cross-sectional study, with a sample of 226 students (47% girls) of public school in the south of Brazil aged between 6 to 11 years-old (8.36 ± 1.46). The cardi

6. Leverage and investment opportunities: the effect on high growth firms
RESUMO O objetivo deste trabalho é investigar se o alto crescimento da firma resultará em redução do nível de dívida. Espera-se que isso aconteça para firmas que sofrem choque idiossincrático positivo nas suas oportunidades de crescimento, o que afetará seu fluxo de caixa e sua lucratividade. Embora a relação entre oportunidades de crescimento (e.

8. Integral Representations of Mittag-Leffler Function on the Positive Real Axis
RESUMO Através do método para encontrar a transformada de Laplace inversa sem o uso de um contorno de integração no plano complexo, mostramos que a função de Mittag-Leffler de três parêmetros, que aparece em muitos problemas associados com cálculo fracionário, possui representações integrais similares no semieixo real positivo. Algumas delas são

9. The relationship of internalizing problems with emotional intelligence and social skills in secondary education students: gender differences
Abstract Internalizing problems (depression, anxiety, social anxiety, somatic complaints, post-traumatic symptoms, and obsession-compulsion) are very important in adolescents’ development. These problems can be related with people who lack social skills and poorly handle their emotions. This study assessed 1358 secondary education students (12-17 years) to

10. Free Vibration Analysis of Multiple Cracked Functionally Graded Timoshenko Beams
Abstract In this paper, authors present the study of free vibration of bending multiple cracked functionally graded material (FGM) beam. Vibration equations of multiple cracked FGM beam were established by using the rotational spring model of cracks, dynamic stiffness method (DSM) and actual position of neutral plane. The frequency equation obtained was in a

11. Transverse permeability determination and influence in resin flow through an orthotropic medium in the RTM process
ABSTRACT Resin Transfer Molding (RTM) process is commonly used to produce high quality polymeric composites with simple or complex geometries in small to large sizes. In RTM process a preformed reinforcement is positioned inside the mold cavity. This dry reinforcement is actually a fibrous porous media whereby resin will flow. The mold is then closed and res

12. PROBLEMAS INVERSOS MAL COLOCADOS EM QUÍMICA
What is an ill-posed inverse problem? The answer to this question is the main objective of the present paper and the pre-requisite to follow the material requires only elementary calculus. The first mathematical formulation of an inverse problem, due to N. H. Abel, together with the fundamental work by Jacques Hadamard, are explored at the beginning of the p
