Existência global de soluções para certos sistemas parabólicos não lineares
(Universidade Federal de São Carlos, 2005-03-02)
In this work, we study the global existence of smooth solutions for certain
systems of the form ut + f(u)x = Duxx, where u and f are vectors and D
is a positive, constant and diagonalizable matrix. We assume that the ...

Indicadores de sustentabilidade urbana: as perspectivas e as limitações da operacionalização de um referencial sustentável
(Universidade Federal de São Carlos, 2000-04-05)
The complexity of the problems deriving from urban environments has required a deeper and more integrated understanding of the reality of these environments as an
essential step toward solutions. The main purpose of this ...
Catalisadores de Ni/Al2O3 promovidos com Au e Ag aplicados à reforma a vapor do metano
(Universidade Federal de São Carlos, 2005-04-08)
15%Ni/Al2O3 catalysts was obtained by impregnation with Ni(NO3)2
aqueous solution and promoted with Au and Ag. The Au was successively
impregnated with aqueous solution of [Au(NH3)4](NO3)3. The Ag was coimpregnated
with ...
