Hi Mike and all,
sorry the late! I had much work in the university these days but now I can return to post in the foruns... Many thanks for the welcome guys, I regularly read the messages here in the iceinspace foruns and to be part of the community is a great honor for me, thanks for the invite Mike!

Well, probably you noticed that my English isn´t good but, I hope at least to be understandable...
regards from Brazil,
Fabio
