Mujeres en la Web 2.0: propuestas para su inclusión digital

“…Esto refuerza las características que promueven la marginación de género. (Rodríguez Gallardo, 2008) Pero ¿qué está pasando en la Web 2.0? Si con Internet aparecen problemas de uso efectivo, la Web 2.0 los acrecienta, si no es posible o no se quiere acceder, menos se crearán contenidos en forma interactiva y colaborativa desde y para la plataforma tecnológica.…”

The Research Program at RIBRAS (Radioactive Ion Beams in Brasil)-III

“…The solenoids make an in-flight selection of the reaction products emerging from the primary target and focus them on a secondary target where the reaction of interest takes place. The 7 Li primary beam and a 9 Be (~12 µ m) target are the standard to produce the 6 He and 8 Li beams via the one proton stripping 9 Be( 7 Li, 6 He) and one neutron pickup 9 Be( 7 Li, 8 Li) reactions. A 3 He gas primary target is used to produce the 8 B and 7 Be beams by the 3 He( 6 Li, 8 B) and 3 He( 7 Li, 7 Be) reactions.…”

“…Most of the experiments performed at RIBRAS consist of elastic scattering and nucleon transfer reactions measurements using light exotic beams such as 6 He, 8 Li and 7 Be. The elastic scattering allows the study of the interacting potential and the total reaction cross section.…”

“…The angular distributions have been analyzed by optical model and four-body CDCC calculations. In Figure 2 we present the elastic angular distributions for the 6 He+ 120 Sn system compared to Optical Model and 4b-CDCC calculations [8]. To compare the reaction cross sections of different systems at different energies, it is convenient to rescale the cross sections and energies in order to overcome trivial effects due to the different sizes and energies with respect to the Coulomb barrier.…”

“…Nucleon transfer reactions induced by exotic projectiles provide, in many cases, important spectroscopic information about states of nuclei not accessible by other means. In particular, the unstable lithium isotopes such as 8,9 Li [6,12,13,14] are important under the nuclear structure point of view and also for astrophysics as they could help to bridge the A = 8 gap. In Figure 4 we present an angular distribution of the proton transfer 12 C( 8 Li, 9 Be) 11 B reaction measured at RIBRAS.…”
