Tópico de submissão do trabalho: 15 melhoramento genético avaliação preliminar do potencial germinativo de linhagens e híbridos de mamoeiro (Carica Papaya L.) em telado.

A espécie Carica papaya L. é, dentre todas as espécies de mamoeiro, a mais cultivada no mundo, apresentando como provável centro de origem o Noroeste da América do Sul, a vertente oriental dos Andes, ou, mais precisamente, a Bacia Amazônica Superior com máxima diversidade genética (Sanches & Dantas, 1999). O Brasil é a nação que apresenta a maior produção de mamão, 1.440.000 t, cultivado em todos os estados da federação. A região Nordeste concentra a maior área de plantio, cerca de 30 mil hectares (Nakamae, 2003). Em Pernambuco a produção é pouco expressiva, correspondendo a 10.097 t obtidas em 578 hectares, equivalente ao rendimento médio anual de 17,74 t / ha (Agrianual, 2006).pdf 147

Galactic cannibalism in the galaxy cluster C0337-2522 at z=0.59

According to the galactic cannibalism model, cD galaxies are formed in the center of galaxy clusters by merging of massive galaxies and accretion of smaller stellar systems: however, observational examples of the initial phases of this process are lacking. We have identified a strong candidate for this early stage of cD galaxy formation: a group of five elliptical galaxies in the core of the X-ray cluster C0337-2522 at redshift z=0.59. With the aid of numerical simulations, in which the galaxies are represented by N-body systems, we study their dynamical evolution up to z=0; the cluster dark matter distribution is also described as a N-body system. We find that a multiple merging event in the considered group of galaxies will take place before z=0 and that the merger remnant preserves the Fundamental Plane and the Faber-Jackson relations, while its behavior with respect to the Mbh-sigma relation is quite sensitive to the details of black hole merging [abridged].Comment: 30 pages, 7 figures, MNRAS (accepted

Heritability of motor skills: Study with monozygotic and dizygotic twins

El objetivo del estudio fue evaluar el poder relativo de contribución genética y ambiental de la variación de capacidades motoras en gemelos monocigóticos y dicigóticos. Método: participado 88 sujetos divididos en 56 monocigóticos y 32 dicigóticos de ambos sexos. Para la evaluación de la flexibilidad fue realizado el test de flexión de cadera; para la potencia de miembros inferiores fue aplicado el test contra movimiento y para la velocidad de desplazamiento, el test de carrera de 30m. Para determinar el índice de heredabilidad, utilizamos la ecuación: (h²) = (S²DZ–S²MZ)/S²DZx100. Fue utilizado tratamiento descriptivo y el test Shapiro-Wilk. Con la varianza de datos fueron calculados valores de tendencia central. Los datos fueron categorizados en percentiles de 25%. Resultados: flexibilidad 16%, velocidad de desplazamiento 83% y potencia de los miembros inferiores 70%.Conclusión: Fue evidenciado mayor heredabilidad para las variables de potencia y velocidad, y mayor influencia ambiental para la flexibilidadThe aim of the study was to assess the relative power of genetic and environmental contributions to the variation of motor skills in monozygotic and dizygotic twins. Method: For this study, participated 88 people divided in 56 monozygotic and 32 dizygotic twins of both sexes. For the assessment the flexibility, was performed hip flexion test, for assessment the lower limb power, was applied the test against movement and the speed of movement, the 30m running test. To determine the index of heritability, was used an equation: (h ²) = (S ²MZ- S²DZ) / S²DZx100. For the statistic, was used the descriptive treatment and Shapiro-Wilk test. The variance values were calculated, through the tendency central values. Data were categorized into percentiles of 25%. Results: Flexibility was 16% by heritability influence, speed of movement 83% of influence and for the lower limbs power were 70%. Conclusion: In this study was demonstrated higher heritability for the variables of lower limbs power and the speed of movement, and for the flexibility, a greater influence was linked for environmental factor
