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 ...
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 ...
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 ...
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 ...
