1. Penetration resistance and agronomic characteristics of soybean affected by soil management and sowing speed systems
ABSTRACT With the short period of the sowing process, we observed an increase in the seeder speed set in several soil management systems that may result in decreased soybean yield and problems with penetration resistance. We aimed to assess the penetration resistance (PR) and agronomic characteristics of soybean on soil tillage and sowing speed. The randomiz

2. Morphological study of polycrystalline SiGe alloy deposited by vertical LPCVD
As device dimensions shrink to the deep-submicron scale, new challenges arises from the very small scale used and even poly crystalline silicon (poly-Si) presents problems as gate electrode. The use of SiGe as gate material can present many advantages over the poly-Si, as it leads to a lower boron penetration and gate depletion. In this paper authors present

3. Método espectro-nodal linear para problemas de transporte de nêutrons na formulação de ordenadas discretas em geometria bidimensional cartesiana / Spectral greens function-linear nodal method for problems of neutrons transport in the discrete ordinates formulation in X, Y Cartesian geometry
Nesta tese o método espectro-nodal linear (SGF-LN) é desenvolvido para a solução numérica de problemas de penetração profunda na formulação de ordenadas discretas (SN) e regime estacionário com fonte de espalhamento isotrópica a uma velocidade em geometria cartesiana bidimensional. Este método é baseado em análise espectral das equações SN in

4. Dois testes de imageamento com GPR em problemas de controle ambiental em regiões tropicais: migração de dunas e localização de dutos de óleo enterrados
Because the penetration depth of Ground Penetrating Radar (GPR) signals is very limited in high conductive soils, the usefullness of this method in tropical regions is not yet completly known. The main objective of this researh is to test the usefullness of the method in Brazil. Two typical problems where GPR has been used in Europe and North American were c
