Avaliação dos fluxos superficiais noturnos de escalares através do método de balanço da camada limite atmosférica
(Universidade Federal de Santa Maria, 2006-04-19)
We report on three campaigns to measure the structure of the nocturnal
boundary layer in cleared and forested areas near Santarém, PA, in 2001 and 2003.
The aim was to describe the temporal evolution of wind and thermodynamic ...
Um estudo do hidrogênio neutro e rádio contínuo em galáxias seyfert com mopra e atca
(Universidade Federal de Santa Maria, 2006-12-01)
In this work 21-cm observations of a sample of 27 southern nearby galaxies (z < 0:018) are presented with a detected Hi line with the Mopra/ATNF radiotelescope. The total
neutral hydrogen gas content has been derived and ...
