O ensino de Gramática(s) é circundado de reveses. Se por muitos séculos a Gramática foi entendida como mero conjunto de regras, a Gramática dita normativa (FARACO, 2008), causando impactos nos modos de ensiná-la, atualmente a multiplicidade de abordagens ... see more

The high-latitude ionosphere is characterised by plasma density irregularities with typical lengths in a wide range of scales (from ~1 m up to ~1000 km). The enhancement of these irregularities caused for instance by severe Space Weather conditions can af... see more

Major geomagnetic storms drive rapid intensification and variability of magnetospheric and iono- spheric current systems that give rise to large ground-induced currents (GIC). Space weather as- sociated GIC pose a serious threat to the reliability of powe... see more

 The magnetosphere-ionosphere system is recognized as a complex and active element affected by space weather and as a region where important scientific questions related to space weather impacts need to be answered. In this framework, there is a high... see more
