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 ...
Espectros de turbulência em terreno complexo
(Universidade Federal de Santa Maria, 2008-08-20)
Throughout this paper a spectral analysis is conducted on the superficial limit layer in complex terrains. The data used were collected in the central part of the state of Rio Grande
do Sul, in the Valley of Jacuí River. ...
Modelo espectral de heisenberg aplicado ao decaímento da turbulência na camada residual
(Universidade Federal de Santa Maria, 2005-10-22)
In the study of the dispersion of contaminants in the atmosphere by computational simulations, the Eulerian approach, based in the diffusionadvection equation, is largely employed. In these simulations, concentration values ...

Observações multifreqüência de quasares CSS utilizando o VLBA
(Universidade Federal de Santa Maria, 2006-12-15)
In this thesis, I discuss the results of radio polarization observations of selected Compact Steep Spectrum sources made with the Very Long Baseline Array using selected frequencies in the 18 cm, 21 cm, 13 cm and 6 cm ...
Magnetoimpedância e dinâmica da magnetização em nanoestruturas ferromagneto/Cu (Ag)/ferromagneto
(Universidade Federal de Santa Maria, 2007-08-17)
In this work the static and dynamic magnetic properties are investigated in FM/i/Cu(Ag)/i/FM tri-layer structured samples where FM is the ferromagnetic multilayer and i is the SiO2 isolating layer. All samples have been ...
Magnetoimpedância e dinâmica da magnetização em multicamadas de Ni81Fe19/Ag e Ni81Fe19/Cu
(Universidade Federal de Santa Maria, 2006-05-29)
In this work, the magnetoimpedance (MI) and magnetization dynamics in multilayered
Ni81Fe19/Ag and Ni81Fe19/Cu samples are studied. The samples were produced by magnetron
sputtering at the Laboratório de Magnetistmo e ...
Gradientes de abundâncias químicas em galáxias espirais
(Universidade Federal de Santa Maria, 2006-06-28)
We used photoionization models in order to derive O/H, N/O, and S/O abundance gradients in three isolated barred spiral galaxies (NGC 1365, NGC 925, NGC 1073) and in nine spiral galaxies (NGC 4501, NGC 4571, NGC 4689, NGC ...
Sistemas convectivos de mesoescala no sul da América do Sul: propagação em série contra o escoamento em baixos níveis
(Universidade Federal de Santa Maria, 2008-03-07)
Serial mesoscale convective system (MCS) events with lifetimes over 18 h and up to nearly 70 h are routinely observed over southeastern South America from infrared satellite imagery during the spring and summer. These ...
