1. Fast Densification Process in Manufacturing Carbon/Carbon Using Vegetable Precursors
ABSTRACT: The carbon/carbon composite manufacturing processes generally use flammable and toxic precursors. In order to make these processes safer, it is interesting to use less toxic and safer precursors to the environment and people. The present study investigates the types of pyrocarbon resulting from composite carbon/carbon densification produced by the

2. Implementação de uma metodologia para mineração de dados aplicada ao estudo de núcleos convectivos / Implementation of methodology for data mining applied to the study of convective nucleous
In this work, a methodology for data mining was implemented using the rough sets theory and applied to the study of convective nucleous. Data mining has been used to analyze large volumes of data trying to identify frequent correlations, patterns, and outliers, in the most varied domains of applications, including scientific research. In this study, data min

3. Lipopolysaccharide structure required for in vitro trimerization of Escherichia coli OmpF porin.
Deep rought mutants, which produce very defective lipopolysaccharides, are unable to export normal levels of porins into the outer membrane. In this study, we showed that lipopolysaccharides from such mutants were also unable to facilitate the trimerization, in vitro, of monomeric OmpF porin secreted by spheroplasts of Escherichia coli B/r. In contrast, lipo

4. Role of the rfaG and rfaP genes in determining the lipopolysaccharide core structure and cell surface properties of Escherichia coli K-12.
Deletions which removed rfa genes involved in lipopolysaccharide (LPS) core synthesis were constructed in vitro and inserted into the chromosome by linear transformation. The deletion delta rfa1, which removed rfaGPBI, resulted in a truncated LPS core containing two heptose residues but no hexose and a deep rought phenotype including decreased expression of
