Transporte térmico em nanofitas de grafeno dopadas com N, B e SI
(Universidade Federal de Santa Maria, 2017-08-28)
The recent progress of the research on carbon nanostructures and the issue of
thermal management have established a great demand in relation to the scientific understanding
of thermal transport in these nanomaterials. ...
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 ...
Utilização de algoritmo genético para a determinação da estabilidade de aglomerados atômicos e as aplicações destes com grafeno
(Universidade Federal de Santa Maria, 2017-01-31)
In this thesis we propose a improvement of the Genetic Algorithm (GA) method that is used to
search the stability of geometry of atomic clusters. The proposed improvements consist by introducing
two new operators: the ...
Estudo de populações estelares em galáxias ativas a partir de cubos de dados no infravermelho próximo
(Universidade Federal de Santa Maria, 2017-08-30)
The correct characterization of the spectral energy distribution (SED) components in Active Galactic
Nuclei (AGN) is the key for their understanding and their role in the evolution of the host
galaxies. In the near-infrared ...
A emissão do gás da região de linhas estreitas em galáxias Seyfert próximas
(Universidade Federal de Santa Maria, 2017-12-21)
The Active Galactic Nuclei (AGNs) show high luminosities ( 109 L ) and emit energy from
the accretion disk around the central Supermassive Black Hole (SMBH). The Narrow Line
Region (NLR) is the only AGN structure spatially ...
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 ...
Modelo lógico da sinergia entre sinalização TGF_ e dano ao DNA no destino celular
(Universidade Federal de Santa Maria, 2017-08-29)
Many factors may cause damages to the DNA, among them we can quote environmental
pollution, ionizing radiations, amongst others. The signalization involved after an instituted
damage consists in activation pathways and/or ...
Estimativas da radiação de onda longa incidente na Região de Pampa Gaúcho
(Universidade Federal de Santa Maria, 2017-12-20)
The incident long wave radiation flux (L ↓) is a parameter that directly influences the
radiation balance on the surface. Measures of this variable are scarce, where the use of
classical equations may be an alternative ...
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 ...
