But the real output is t

4. Causality enters the taxes of growth of the developed and emergent countries / Causalidade entre as taxas de crescimento dos paÃses desenvolvidos e emergentes
Through the use of statistical and econometric instrumentals for the analysis of time series, this work aims to verify the relationships between the economic growth rate of developed and emergent countries. For so much, it was used of a sample containing the real economic growth rate of those countries in the period of 1970-2007. With base in this study, it

This work deals with the incompressible flow around pairs of rigid and immovable circular cylinders in tandem arrangements. There are two goals in this research: the first one is to find causality relationships between physical characteristics of the flow and the changes that are observed in the forces and in the flow field with the variation of the Reynolds

12. GAMYB-like Genes, Flowering, and Gibberellin Signaling in Arabidopsis1
We have identified three Arabidopsis genes with GAMYB-like activity, AtMYB33, AtMYB65, and AtMYB101, which can substitute for barley (Hordeum vulgare) GAMYB in transactivating the barley α-amylase promoter. We have investigated the relationships between gibberellins (GAs), these GAMYB-like genes, and petiole elongation and flowering of Arabidopsis. Within 1
