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 ...

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 ...

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), ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
