Hi there, nice pic, so your back did you have a nice time?
Yep yep! Nice weather, nice mountains, nice people :)
actually - realizing a childhood dream, seeing friends/family, a work-related trip?
Although I found that the nearby Nova Friburgo town received some Hungarian colonists in the past (link), and also got to know new good friends, the basic reason of the trip was a conference. :) Then of course I took advantage of SP and set out to meet new friends and mountains in Brazil.
Anything to do with sustainable development?
Boh! :) The topic was diffuse aquatic pollution.
Could you tell me what your PhD thesis is (/going to be) about?
It may sound odd, but my topic is water quality of urban rainfall runoff :)
