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 ...
Dinâmica das propriedades térmicas e do fluxo de calor no solo em uma área de pastagem no bioma Pampa
(Universidade Federal de Santa Maria, 2017-08-07)
For the thermal characterization of a soil it is necessary to determine its thermal properties,
because they describe how the storage and the propagation of thermal energy vary
a function of time and depth. This knowledge ...
Aperfeiçoamento de modelos numéricos para estimativa de propriedades térmicas do solo
(Universidade Federal de Santa Maria, 2019-09-02)
Understanding the soil thermal properties, in particular, diffusivity , volumetric capacity and conductivity is important in applications of several related areas, mainly soil-plant-atmosphere interaction. Studies to ...
Desenvolvimento de um modelo lagrangiano para estimar a dispersão de escalares passivos em condições de meandro do vento horizontal
(Universidade Federal de Santa Maria, 2017-02-24)
The description of the effects of the wind meandering in the scalar dispersion is a challenging
task, since this type of flow represents a physical state characterized by multiple
scales. In this study, a Lagrangian ...
Tomografia PCA aplicada a cubos de dados no infravermelho próximo para a galáxia Seyfert Mrk 1066
(Universidade Federal de Santa Maria, 2014-06-30)
In this work, we apply the PCA Tomography technique (Principal Component Analysis) to data
cubes for the central region of the Seyfert 2 galaxy Mrk 1066. The observations were done with
the NIFS (Near-infrared Integral ...

(Universidade Federal de Santa Maria, 2014-08-15)
The specific heat and the condensation energy of a two-dimensional Hubbard model,
suitable to discuss high Tc superconductors (HTSTC), is studied taking into account
hopping to first (t) and second (t2) nearest neighbors. ...
Efeito do tratamento térmico na relaxação magnética de microfios amorfos de CoFeSiB recobertos por vidro
(Universidade Federal de Santa Maria, 2012-02-27)
Magnetoimpedance has been proved to be an excellent tool to study the magnetization
dynamics and the ferromagnetic resonance (FMR) linewidth provides a convenient way
for measuring damping parameters in magnetic materials. ...

(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 ...
Estudo de primeiros princípios de nanofios de inas submetidos a tensões extremas
(Universidade Federal de Santa Maria, 2015-03-30)
The ability to manipulate materials at the atomic scale turn it possible to look
for materials at the nanoscale that can supersede the performance of their bulk counterparts
in specific tasks. Nanowires, due to their ...
Estudo teórico de antissítios e impureza substitucional de oxigênio em nanofio de SiC
(Universidade Federal de Santa Maria, 2010-09-23)
In this work first we perform a study about the stability, and the electronic properties of SiC growth in the [111] direction when defects are present. We use the supercell method and the dangling bonds on the surface of ...
