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 ...
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 ...

(Universidade Federal de Santa Maria, 2006-05-31)
In this work, the effect of the thickness on the statistical properties of Barkhausen noise and dynamic hysteresis in thin films with compositions Fe73.5Cu1Nb3Si13.5B9,
Fe73.5Cu1Nb3Si16.5B6, Fe73.5Cu1Nb3Si18.5B4 and ...
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 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 ...
