13. Metodologia para implementação do modelo Markoviano em analise confiabilistica de sistemas
Em uma economia globalizada e competitiva, com regras modernas de segurança, leis ambientais e de responsabilidade, o avanço da tecnologia permite o desenvolvimento de equipamentos e sistemas cada vez mais complexos, capazes de satisfazer as exigências impostas e competir com os concorrentes existentes no mercado, sendo um dos parâmetros de diferença, a

14. Nuclear Overhauser effect study and assignment of D stem and reverse-Hoogsteen base pair proton resonances in yeast tRNAAsp.
Nuclear Overhauser effects (NOEs) in yeast tRNAAsp were found for all four GU and G psi base pairs. NOEs of both reverse-Hoogsteen pairs were identified by comparison with a purine C8 deuterated sample. Several NOEs involving these resonances were also found which are clearly between single protons on adjacent base pairs. These interbase NOEs, combined with

15. Anticodon-anticodon interaction induces conformational changes in tRNA: yeast tRNAAsp, a model for tRNA-mRNA recognition.
The crystal structure of yeast tRNAAsp enables visualization of an anticodon-anticodon interaction at the molecular level. Except for differences in the base stacking and twist, the overall conformation of the anticodon loop is quite similar to that of yeast tRNAPhe. The anticodon nucleotide triplets, GUC, of two symmetrically related molecules form a minihe
