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 ...
Estudo da difusão turbulenta empregando modelos estocásticos Lagrangeanos
(Universidade Federal de Santa Maria, 2007-03-09)
In this work, the Lagrangian stochastic particle model LAMBDA is utilized to simulate the dispersion and the transport of contaminants under different atmospheric conditions. The analysis employs three different field ...
Catálogo de dados espectroscópicos de regiões HII e estudos aplicados
(Universidade Federal de Santa Maria, 2009-03-20)
Quantitative measurements of line intensities have been made since the beginning of the last century. The quantity and quality of the data available have increased drastically with the advent of electronic detectors. ...

Variações espaciais de propriedades físicas em Puppis A
(Universidade Federal de Santa Maria, 2009-05-27)
The current work presents some physical proprieties from a region of the galactic supernova remnant Puppis A. For that, long slit spectrophotometric data were obtained in distinct positions. The data were obtained in 14 ...
Estudo de aglomerados estelares das nuvens de magalhães usando fotometria CCD na banda V
(Universidade Federal de Santa Maria, 2005-06-02)
In this work we present CCD photometry in the V band for 13 star clusters in the Magellanic Clouds (LI0, L54, L59, L85, L96, NGC 1818, NGC 1866, NGC 1868, NGC 1978, NGC 2157, NGC 2213, NGC 2214, Hll). Photometric calibration ...
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 ...
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 ...
Avaliação do método do balanço da camada limite para a estimativa de fluxos turbulentos noturnos
(Universidade Federal de Santa Maria, 2006-10-27)
This work is about to verify the performance of the boundary layer budgeting method as alternative for measuring the surface turbulent fluxes in conditions that allow the
validation of the measurements with data taken ...
