Estudo teórico de nanodomínios de grafeno e siliceno em carbeto de silício
(Universidade Federal de Santa Maria, 2018-02-20)
In this work the structural, optical and electronic properties of hexagonal monolayer compounds
of silicon carbide (h-SiC) in pristine form and in the presence of defects like graphene (h-
SiC-C) and silicene (h-SiC-Si) ...
Adsorção de cluster de ouro em materiais bidimensionais
(Universidade Federal de Santa Maria, 2017-07-31)
In this work, we studied the interaction of Au34 gold cluster with different two-dimensional
materials. Au clusters, differently of their macroscopic form, are chemically reactive. Their
use requires substrates. The ...
Modelagem da interação superfície- atmosfera: calibração dos modelos sib2 e sib3 em uma área de pastagem no sul do Brasil
(Universidade Federal de Santa Maria, 2018-02-08)
The Simple Biosphere Model (SiB) modelwas developed to represent and estimate the interactions
between soil, vegetation and atmosphere, which describe the transfer processes of energy, mass
and momentum. In this sense, ...
Análise da influência ambiental sobre galáxias de núcleo ativo usando o levantamento MaNGA
(Universidade Federal de Santa Maria, 2017-07-04)
We examined the dependency between nuclear activity in galaxies and the environment in which they are located. Using data from the MaNGA survey from the Sloan Digital Sky Survey IV, we analyzed the gas kinematics of 62 ...
Diagramas de fase do modelo de Ising definido sobre dois grafos acoplados
(Universidade Federal de Santa Maria, 2017-08-07)
In this work we study a model of two coupled complex networks, with the purpose to study
the phase diagrams and the metastability of the system. The networks have internal ferromagnetic
interactions and are coupled to ...
Os primeiros 62 AGNS observados com o SDSS-IV MANGA: cinemática estelar e do gás
(Universidade Federal de Santa Maria, 2018-07-25)
Active galaxies exhibit a great luminosity in central region that can not be explained only by the
emission of the stars of the galaxy, but by the presence of an active galactic nucleus (AGN). In
this scenario, gravitational ...
Estudo teórico da interacção de oxigênio com nanotubos de BC2N
(Universidade Federal de Santa Maria, 2011-04-19)
Using first principles calculations based on the Density Functional Theory (DFT)
with spin polarization and norm conserving fully separable pseudopotentials, we have
studied the structural and electronic properties of the ...
Estudo de impureza de európio em PbSe e PbTe. Uma investigação de primeiros princípios
(Universidade Federal de Santa Maria, 2014-01-30)
In this work properties were studied the structural, electronic and magnetic semiconductors
PbSe and PbTe doped with europium (Eu) in the crystalline phase. The
investigation is performed within the density functional ...
Caracterização de filmes finos magnéticos em altas frequências
(Universidade Federal de Santa Maria, 2014-08-29)
In order to determine the complex permeability of ferromagnetic samples in the GHz
range, measurement techniques with transmission lines are most appropriate. These techniques
use the modification of the scattering ...
Conjunto de testes de garantia de qualidade de um software para planejamento radioterápico
(Universidade Federal de Santa Maria, 2014-05-29)
Radiotherapy can be highlighted as one possible treatment of cancer. From this point of view, the planning system for radiotherapic treatment is crucial. In order to check the software for the computerized planning of the ...
