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 ...
Magnetoimpedância como ferramenta para a caracterização magnética de microfios amorfos
(Universidade Federal de Santa Maria, 2006-09-22)
The possibility of exploring the magnetic properties of amorphous microwires in technological applications has attracted the attention of the scientific community in the last years. Beyond, the magnetoimpedance effect has ...
Estudo das propriedades térmicas de nanofios de silício
(Universidade Federal de Santa Maria, 2006-06-25)
In this work we present the results of the study of thermal stability of silicon
nanowires (SiNWs), carried out by computational simulation using Monte Carlo
methods. The study focuses on cylindrical nanowires grown in ...

Mapas de densidade e velocidade e estimativa de distância da região H II galáctica NGC 2579
(Universidade Federal de Santa Maria, 2006-08-17)
An observational study was accomplished about the range of eletron density in the HIIregion NGC 2579 and estimate its distance from the 8un and from the centre of the Galaxy. Long slit spectrophotometric data with high ...
A hipótese de turbulência localmente isotrópica e a universalidade da constante de Kolmogorov
(Universidade Federal de Santa Maria, 2006-05-03)
According to the Kolmogorov's fully developed turbulence theory established in 1941, there is an equilibrium range in which phenomenological quantities associated to the turbulence flow are described by laws of universal ...
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 em multicamadas de Ni81Fe19/Cu com a corrente de sonda perpendicular ao plano do filme
(Universidade Federal de Santa Maria, 2006-06-02)
In this work the behavior of the magnetoimpedance (MI) in ferromagnetic
multilayered (Ni81Fe19/Cu) produced by magnetron sputtering was studied. In all
measurements, the probe current was applied perpendicularly to the ...
