2. Associação entre insatisfação com a imagem corporal e aptidão física relacionada à saúde em adolescentes
Resumo O objetivo deste estudo foi estimar a prevalência de insatisfação com a imagem corporal e verificar a associação entre a insatisfação pela magreza e pelo excesso de peso e componentes da aptidão física relacionada à saúde em adolescentes. Participaram 1.058 adolescentes (570 moças e 488 rapazes), com média de idade de 16,3(± 1,0) anos. A

3. Fitness components of Monosporascus cannonballus isolates from northeastern Brazilian melon fields
Monosporascus root rot and vine decline caused by Monosporascus cannonballus is one of the most important melon yield-limiting diseases in northeastern Brazil. This study investigated the fitness components of 57 isolates of M. cannonballus obtained from Brazilian melon fields by evaluating: i) their mycelial growth rate (MGR), and perithecia and ascospore p

4. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

5. Aptidão física relacionada à saúde entre escolares de diferentes níveis socioeconômicos e estágios maturacionais
The present study congregate three articles that compose this dissertation of Masters Degree in Physical Education from Catholic University of Brasília. Adolescents present lower indices for a good health-related physical fitness (HRPF) and thereby higher risks to develop diseases associated to sedentarismo. The components of HRPF, strength and muscle endur

6. Optimization of napthalene biodegradation by a genetic algorithm based response surface methodology
Naphthalene biodegradation was studied using the bacterial strain Pseudomonas putida S2. Three medium variables out of seven medium components were selected under Plakett-Burman (PB) design as having significant response on naphthalene biodegradation. These variables were citric acid (additional carbon sources), ammonium sulfate and sodium chloride. The leve

7. Genetic programming: crossover operators, building blocks and semantic emergence / Programação genética: operadores de crossover, blocos construtivos e emergência semântica
Evolutionary algorithms are heuristic methods used to find solutions to optimization problems. These methods use stochastic search mechanisms inspired by Natural Selection Theory. Genetic Algorithms and Genetic Programming are two of the most popular evolutionary algorithms. These techniques make intensive use of crossover operators, a mechanism responsible

9. Distorção da proporção sexual induzida por Spiroplasma, um agente androcida, em Drosophila / Sex-ratio distortion induced by Spiroplasma, a male-killing agent, in Drosophila
Elementos citoplasmáticos egoístas (ECEs) sao bactérias que apresentam transmissão predominantemente vertical e se mantém na população hospedeira através do aumento relativo da produção de fêmeas infectadas. Nesses casos a seleção natural favorece mecanismos de manipulação da reprodução do hospedeiro (feminização, partenogênese, mortalida

10. Efeito de 12 semanas de treinamento com pesos sobre a força muscular e a composição corporal de mulheres idosas
Introduction: Reductions in strength and alterations on body composition, observed with normal aging, may compromise the quality of life of older people. Having said that, regular systematic practice of resistance exercises has been recommended, especially for older adults. Objective: To evaluate the effects of 12 weeks of resistance training in strength and

11. Effects of differential weekly frequencies of weight training on body composition and motor capacities in older men / Efeitos de diferentes frequencias semanais de treinamento com pesos sobre a composição corporal e capacidades motoras em homens idosos
The effects of weight training made with different intensities, frequencies and volumes provide beneficial answers and are well spread among young people and athletes. However, studies that look for the effects of weight training held at different frequencies weekly are limited to elder populations. So, the purpose of this study was to analyze and compare th
