Theoretical parameters of trailing vortices versus aspect ratio of wing models
We perform 2D-PIV measurements to characterize trailing vortices in NACA0012 wing models for aspect ratios ranging between 1 and 2.5, and for chord-based Reynolds numbers from 7000 to 40000. Firstly, and regarding the influence of the Reynolds number, the increase of this dimensionless parameter generates a more concentrated and intense vortex, presenting, therefore, an increase in all its characteristic magnitudes: maximum azimuthal velocity and vorticity. Secondly, the greater the aspect ratio, the greater the vortex strength is observed. Thirdly, the radial location of the peak of the azimuthal velocity has a strong decay as the aspect ratio increases for Re=7000, but it changes its trend for Re=40000.Universidad de Málaga.

Sistema de información geográfica para la generación de mapas temáticos (SIGMAT). Producción de cartografía temática
El Sistema de Información Geográfica para la Generación de Mapas Temáticos (SIGMAT) es una nueva
herramienta que incorpora las más avanzadas tecnologías y métodos a la producción de cartografía temática.
Mediante la introducción de numerosos asistentes facilita todas las tareas de gestión, elaboración y publicación
automatizada de los mapas controlando así el ciclo de vida completo de los mismos. Su diseño permite actualizar
automáticamente los mapas cuando cambian los datos vinculados.Geographic Information System for Thematic Map Generation (SIGMAT from spanish) is a new tool that incorporates

On the Mechanism of Magnesium Storage in Microand Nano-Particulate Tin Battery Electrodes
This study reports on the electrochemical alloying-dealloying properties of Mg2Sn
intermetallic compounds. 119Sn Mössbauer spectra of -Sn powder, thermally alloyed cubic-Mg2Sn,
and an intermediate MgSn nominal composition are used as references. The discharge of a
Mg/micro-Sn half-cell led to significant changes in the spectra line shape, which is explained by a
multiphase mechanism involving the coexistence of c-Mg2Sn, distorted Mg2����� Sn, and Mg-doped
-Sn. Capacities and capacity retention were improved by using nanoparticulate tin electrodes.
This material reduces significantly the diffusion lengths for magnesium and contains surface SnO
and SnO2, which are partially electroactive. The half-cell potentials were suitable to be combined
versus the MgMn2O4 cathodes. Energy density and cycling properties of the resulting full Mg-ion
cells are also scrutinize
