Lateral asymmetries are in everywhere as well as in all movements made by man, which become more evident in movements of sport. The asymmetry is particularly pointed out in futsal when players, even with clear opportunity of making use of their non-preferred foot, try to place the ball in order to execute the action with their preferred foot. The study of asymmetry in futsal is quite relevant, once ambidextrous players present advantages in their performances during a match, which can help futsal athletes not only in their performance improvement but also with the prescription of training. For this reason, the present study had questioned: is there symmetry/asymmetry at the performance of lower contralateral limbs during actions with the possession ball (pass, receiving a ball and kick into the goal) during a futsal match? Thus, the aim of this study was to analyze the symmetry/asymmetry using the preferred and non-preferred foot in actions with the possession ball (pass, receiving and shoot) in adult Futsal's players (professional). The winner team of eight matches of the 2012 FIFA Futsal World Cup was analyzed. An average of 75 players had all their actions (pass, receiving a ball and shot on goal) using their lower limbs during the match analyzed. However, their actions with the head and torso were not analyzed. The games were acquired through a television broadcast. All eight matches were followed by an appraiser through a computer. The Skout® software was used to collect the data, taking notes of the player involved, the type of action (pass, receiving a ball and shot on goal), its foot used (preferred or non-preferred foot) and if the execution was correct or wrong. These data were saved in a text file, in the form of a matrix and imported into the Matlab® software, where was analyzed the following parameters: frequency of occurrence of each action with each foot and quantity of correct and wrong occurrences performed with...

The research objective was to study the genetic diversity of morphological traits in Eucalyptus grandis progenies growing under paclobutrazol regulator effects. The progeny trail was set up through design of randomized blocks. The morphological changes occurred before and during the plant flowering were analyzed. The estimation of genetic parameters were for plant height and stem diameter. The paclobutrazol have caused changes on plant development being strong by the beginning and becoming lightening through the evaluations. The coefficients of variation have shown there is higher genetic diversity within than among progenies for the studied traits. Therefore, it can have high efficiency on selection within progenies in the Eucalyptus grandis breeding program.

A colheita é uma das principais etapas no processo de produção de sementes de soja. O momento adequado para se efetuar a colheita pode variar em função do tipo de colheita e do grau de umidade das sementes. Neste sentido, o objetivo dessa pesquisa foi determinar as alterações fisiológicas de sementes de soja colhidas de forma manual e mecânica com diferentes teores de água. Para tanto, utilizaram-se sementes das cultivares Embrapa 48 e FTS Águia, que têm diferenças no teor de lignina do tegumento, colhidas de forma manual e mecanicamente com 18,0; 15,0 e 12,0% de água. Após a colheita, as sementes foram submetidas à secagem, e a qualidade das sementes foi avaliada pelos testes de germinação, emergência de plântulas, tetrazólio (viabilidade e vigor), envelhecimento acelerado e índice de velocidade de emergência de plântula. Em seguida, as sementes foram armazenadas (20 °C e 45% UR do ar) e analisadas logo após a colheita e aos seis meses de armazenamento. Os resultados obtidos indicam que o parâmetro fisiológico das sementes de soja, não é afetado, quando: se realiza colheita manual com grau de umidade das sementes de 11,4% a 18,4%; e para sementes colhidas à máquina, com grau de umidade entre 12,0% a 15,9%; mantendo a qualidade fisiológica mesmo após seis meses de armazenamento.

Trata-se de discutir as críticas a conceitos insuficientes de liberdade, tais como elas aparecem na Filosofia do direito, de Hegel. Com isto, espera-se expor os verdadeiros problemas que a teoria hegeliana do Estado procura resolver. Tais problemas permitem lançar novas luzes em alguns aspectos decisivos da teoria hegeliana do reconhecimento.
