Modelagem computacional de redes genéticas regulatórias
(Universidade Federal de Santa Maria, 2016-09-30)
In biology, regulatory networks are sets of macromolecules, mostly proteins and
RNAs that interact to execute task. The main players in regulatory networks are DNAbinding
proteins, also called transcription factors as they ...
Efeitos de interações de curto alcance e tamanho de clusters em sistemas desordenados
(Universidade Federal de Santa Maria, 2015-08-04)
The competition between cluster spin glass and ferromagnetism or antiferromagnetism
is studied in this work. The model considers clusters of spins with short-range
ferromagnetic or antiferromagnetic interactions (J0) and ...
Análise das propriedades dinâmicas e estruturais da água confinada entre placas hidrofóbicas
(Universidade Federal de Santa Maria, 2013-04-26)
In this work we studied the properties of confined water by graphene sheets via Classical
Molecular Dynamics. The main objective of this dissertation is to understand how the
structural and dynamic properties of confined ...
Exchange bias em multicamadas de NiFe/IrMn/Ta: um estudo através da magnetorresistência anisotrópica
(Universidade Federal de Santa Maria, 2015-08-07)
In this work a study of the exchange interaction between ferromagnetic (NiFe) and antiferromagnetic
(IrMn) layers was done through structural, magnetic and electric characterization.
NiFe/IrMn/Ta films were grown with ...
Avaliação do "magnetron sputtering" como técnica para obtenção de MgB2
(Universidade Federal de Santa Maria, 2014-08-26)
In this work a survey of the potentialities and limitations of magnetron sputtering as a
tool for the production of MgB2 superconductors thin films has been made. Instead of the usual
approaches, like co-deposition onto ...
Análise de populações estelares e subestruturas em aglomerados de galáxias
(Universidade Federal de Santa Maria, 2015-08-25)
In this work, we investigated differences between stellar populations of galaxies that are part
of a cluster with and without substructures. We used optical spectra obtained from Sloan Digital
Sky Servey III DR10 for the ...
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 ...
