Caracterização de fungos presentes em solos sulfetados da Antártica e sua avaliação para estudos em processos de biolixiviação de metais
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MICROBIOLOGIAPrograma de Pós-Graduação em MicrobiologiaUFMG, 2020-02-19)
Antarctica stands out for its low temperatures and low availability of nutrients, intense solar radiation and strong winds in its different ecosystems. In Antarctica there are soils with different physical and chemical ...
Polarização interestelar na região de interação entre as Bolhas Local e Loop I
(Universidade Federal de Minas GeraisUFMG, 2009-03-05)
The interstellar medium in the proximity of the Sun, between 65 and 250 pc, is composed by a quite irregular, low density cavity (nHI < 0:005 cm..3), known as the Local Bubble. The fraction of this cavity filled with high ...

Having as a reference photographs and the commercial plans of the Alfa-700 bus belonging to Pillapa Metal company from Pelileo, it is aimed to improve that model of inter provincial bus, beginning with the modeling in the ...
Multi-spacecraft study of the January 21st 2005 ICME: Evidence of Current Sheet Substructure Near the Periphery of a Strongly Expanding, Fast Magnetic Cloud
(Springer, 2007-12)
We examine the near-Earth Interplanetary Coronal Mass Ejection (ICME) apparently related to the intense Solar Energetic Particle (SEP) event of 20 January 2005. Our purpose is to contribute to the understanding of the ...
Linking two consecutive non-merging magnetic clouds with their solar sources
(American Geophysical Union, 2009-12)
On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dstpeak = −263 nT). This structure has been associated ...
Very intense geomagnetic storms and their relation to interplanetary and solar active phenomena
(Elsevier, 2012-05)
We revisit previous studies in which the characteristics of the solar and terplanetary sources of intense geomagnetic storms have been discussed. In this particular analysis, using the Dst time series, we consider the very ...
