Modos quase-normais e a correspondência AdS/CFT
(Universidade Federal de Santa Maria, 2008-04-25)
The electromagnetic and gravitational quasinormal mode spectra of plane-symmetric anti-de Sitter black holes are investigated in the present work. According to the AdS/CFT
correspondence, the black hole quasinormal frequencies ...
Zimora - um modelo numérico 3d de dispersão atmosférica
(Universidade Federal de Santa Maria, 2009-08-27)
In this thesis, we presents a development and validation of a 3D numerical model for the
advection-diffusion equation. Models of this kind has been developed for scientific investigations
and to support atmospheric emissions ...
Propriedades estruturais e eletrônicas de partículas de 13 e 55 átomos de metais de transição
(Universidade Federal de Santa Maria, 2012-06-01)
In this thesis we performed a theoretical study of the structural, electronic, and magnetic properties of transition metal (TM) particles using two models, with 13 and 55 atoms to describe clusters, nanoparticles (NPs), ...
Gradientes de abundâncias químicas em galáxias espirais
(Universidade Federal de Santa Maria, 2006-06-28)
We used photoionization models in order to derive O/H, N/O, and S/O abundance gradients in three isolated barred spiral galaxies (NGC 1365, NGC 925, NGC 1073) and in nine spiral galaxies (NGC 4501, NGC 4571, NGC 4689, NGC ...
Sistemas bidimensionais formados por silício e germânio: um estudo de primeiros princípios
(Universidade Federal de Santa Maria, 2015-07-14)
First principles calculations within the density functional theory have been used to
study the main structural, energetic, electronic, and optical properties of hydrogenated Si
and Ge in the 2D structures (silicane and ...
UM MÉTODO MULTIESTATÍSTICO PARA IDENTIFICAÇÃO DE VIAS GENÉTICAS DIFERENCIALMENTE EXPRESSAS
(Universidade Federal de Santa Maria, 2016-08-19)
The determination of the causes and origins of a given disease is a complex undertaking, considering
that there is a large number of genes engaged that interact with each other (Watson,
2006). Bioinformatics experts working ...
Transição semicondutor-metal em nanocristais de VO2 termoeletricamente ativada
(Universidade Federal de Santa Maria, 2015-05-26)
In this thesis, structural and electrical characteristics are investigated around the thermally
triggered semiconductor to metal transition in VO2 thin films. The films, the metallics
electrodes, as well as SiO2 buffer ...
O papel da competição por luz e da troca de nutrientes na interação entre plantas
(Universidade Federal de Santa Maria, 2003-12-03)
At this work we present two models to describe de growth dynamics of interacting plants. The first system that we have used describes de water dynamics, and then relates it with the cations in the ground and with the biomass ...
Avaliação dos fluxos superficiais noturnos de escalares através do método de balanço da camada limite atmosférica
(Universidade Federal de Santa Maria, 2006-04-19)
We report on three campaigns to measure the structure of the nocturnal
boundary layer in cleared and forested areas near Santarém, PA, in 2001 and 2003.
The aim was to describe the temporal evolution of wind and thermodynamic ...
Calibração do modelo de superfície noah lsm: aplicação em uma região agrícola no sul do Brasil
(Universidade Federal de Santa Maria, 2016-05-20)
In this study, simulated to net radiation and energy flux in a region with rotation of crops, for two distinct periods: Period 1 (01 / Feb / 2009 to 31 / Jan / 2010) and period 2 (14 / Dec / 2009 to 28 / Apr / 2010). In ...
