Estudio antropométrico de la forma corporal de bailarines adolescentes de ballet

El desempeño técnico artístico de los bailarines exitosos está relacionado a tipos específicos de forma corporal. El objetivo de esta investigación es comparar la forma corporal de bailarines adolescentes de ballet en relación a ejecutantes de danza moderna y folclórica. Se estudiaron bailarines cubanos de la Escuela Nacional de Ballet y de la Escuela de Danza Moderna y Folclórica, con edades comprendidas entre los 15 y 18 años. Se aplicó un protocolo antropométrico de 10 mediciones para estimar el somatotipo antropométrico, utilizándose el método de Carter-Heath. El somatotipo promedio de las estudiantes de ballet fue Ectomórfico Balanceado (2.1-2.6-4.4) y el de las estudiantes de danza moderna y folclórica fue Somatotipo Central (2.5-3.2-3.5); en los varones de ambas especialidades se encontró un somatotipo promedio Meso-Ectomórfico. Las estudiantes de ballet se distribuyeron en siete categorías somatotípicas con las mayores tendencias de clasificación para los somatotipos Ecto-Mesomórfico (37.0%) y Ectomórfico Balanceado (37.0%). Los estudiantes de ballet cuantificaron una tendencia predominante para la categoría Meso-Ectomórfico (63.0%), en una dispersión de cuatro categorías clasificatorias. Se registraron diferencias estadísticamente significativas en las distribuciones somatotípicas para las estudiantes femeninas y similitudes para los estudiantes varones de ballet y danza moderna y folclórica. Los estudiantes de ballet de ambos sexos registraron distribuciones clasificatorias amplias, idénticas para los varones, que no expresaron una homogeneidad mayor para la forma corporal respecto a los de danza moderna y folclórica. Las dispersiones en frecuencias somatotípicas para los estudiantes de ballet, fundamentalmente las bailarinas, no se corresponden con lo esperado para una población de bailarines de alto nivel técnico-artístico.To be successful in classical ballet performance, it seems dancers must conform to specific morphological standards. The purpose of this research is to compare the human shape of adolescent ballet dancers in relation to modern-folkloric dancers. Cuban dancers from the National Ballet School and the Modern-Folkloric Dance School, aged 15-18 years old, participated in this study. An anthropometric protocol of 10 measurements was applied in order to determine the anthropometric somatotype using the Carter-Heath procedure. The female media somatotype of ballet dancers was Balanced Ectomorfic (2.1-2.6-4.4) and the media somatotype of modern-folkloric dancers was Central (2.5-3.2-3.5); being Ecto-Mesomorfic for male dancers of both disciplines. Female ballet dancers were distributed into seven categories with their main classificatory trends for Meso-Ectomorfic (37.0%) and Balanced Ectomorfic (37.0%) somatotypes. Male ballet dancers showed a high trend for Ecto-Mesomorfic category (63.0%), being distributed into four categories. Statistical differences between female ballet and modern-folkloric dancers were obtained from the comparison of somatotypes distributions; while similitudes were found for male dancers of both disciplines. Male and female ballet dancers registered wide classificatory distributions, identical for males, who didn't show a higher homogeneity for human shape than modern-folkloric dancers. The spread of somatotypic frequencies of ballet dancers, mainly females, didn't correspond with what is expected for a population of dancers of high technical-artistic mastery.Asociación de Antropología Biológica de la República Argentin

Direct Measurement of Nuclear Dependence of Charged Current Quasielastic-like Neutrino Interactions using MINERvA

Charged-current $\nu_{\mu}$ interactions on carbon, iron, and lead with a final state hadronic system of one or more protons with zero mesons are used to investigate the influence of the nuclear environment on quasielastic-like interactions. The transfered four-momentum squared to the target nucleus, $Q^2$, is reconstructed based on the kinematics of the leading proton, and differential cross sections versus $Q^2$ and the cross-section ratios of iron, lead and carbon to scintillator are measured for the first time in a single experiment. The measurements show a dependence on atomic number. While the quasielastic-like scattering on carbon is compatible with predictions, the trends exhibited by scattering on iron and lead favor a prediction with intranuclear rescattering of hadrons accounted for by a conventional particle cascade treatment. These measurements help discriminate between different models of both initial state nucleons and final state interactions used in the neutrino oscillation experiments

Traditional knowledge of wild edible plants used in the northwest of the Iberian Peninsula (Spain and Portugal): a comparative study

<p>Abstract</p> <p>Background</p> <p>We compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula as follows: Campoo, Picos de Europa, Piloña, Sanabria and Caurel in Spain and Parque Natural de Montesinho in Portugal.</p> <p>Methods</p> <p>Data on the use of 97 species were collected through informed consent semi-structured interviews with local informants. A semi-quantitative approach was used to document the relative importance of each species and to indicate differences in selection criteria for consuming wild food species in the regions studied.</p> <p>Results and discussion</p> <p>The most significant species include many wild berries and nuts (e.g. <it>Castanea sativa, Rubus ulmifolius, Fragaria vesca</it>) and the most popular species in each food-category (e.g. fruits or herbs used to prepare liqueurs such as <it>Prunus spinosa</it>, vegetables such as <it>Rumex acetosa</it>, condiments such as <it>Origanum vulgare</it>, or plants used to prepare herbal teas such as <it>Chamaemelum nobile</it>). The most important species in the study area as a whole are consumed at five or all six of the survey sites.</p> <p>Conclusion</p> <p>Social, economic and cultural factors, such as poor communications, fads and direct contact with nature in everyday life should be taken into account in determining why some wild foods and traditional vegetables have been consumed, but others not. They may be even more important than biological factors such as richness and abundance of wild edible flora. Although most are no longer consumed, demand is growing for those regarded as local specialties that reflect regional identity.</p
