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, ...

Water is a natural resource of extreme importance, humans, animals and plants depends directly on it to survive. The state of RS stands out in national scenario as a big producer of many crops, which demand huge amounts ...

Milk is one of the most important foods for human society. Its main components are water, lactose, fat, protein and minerals. It is a delicate and highly perishable product, with its physical, chemical and biological easily ...

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 ...

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) ...

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 ...
