Techniques for estimating unknown terms - such as eddy diffusivity and counter-gradient - in atmospheric flow are presented in this study. The methos is also used to identify the source term in atmospheric pollution. The ...

Tree experiments were conducted in Santa Maria end Constantina (State of Rio Grande do Sul- Brazil), objecting to determine the best plant population of type II e III of common bean grown in the season and latter season, ...

In this work the static and dynamic magnetic properties are investigated in FM/i/Cu(Ag)/i/FM tri-layer structured samples where FM is the ferromagnetic multilayer and i is the SiO2 isolating layer. All samples have been ...

Serial mesoscale convective system (MCS) events with lifetimes over 18 h and up to nearly 70 h are routinely observed over southeastern South America from infrared satellite imagery during the spring and summer. These ...

In this work, the effect of the thickness on the statistical properties of Barkhausen noise and dynamic hysteresis in thin films with compositions Fe73.5Cu1Nb3Si13.5B9, Fe73.5Cu1Nb3Si16.5B6, Fe73.5Cu1Nb3Si18.5B4 and ...

Barkhausen noise (BN) corresponds to the voltage pulses induced in a sensing coil wound around a ferromagnetic material submitted to a variable magnetic field. It is related to the irregular motion of the domain walls (DWs) ...

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 ...

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 ...

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 ...
