1. A forma sonata em descontinuidades e bifurcações / Sonata Form in Discontinuities and Bifurcations.
Este trabalho propõe um novo modelo de análise musical, em complementação à análise harmônica tradicional, com o estabelecimento de dois atratores - a partir da dilatação da estabilidade harmônica a partir do séc. XVIII e da resolução da dicotomia temática, condições fundamentais para a existência do modelo Sonata - definidos como catástrof

2. VERGONHA: A REVELAÇÃO DA CATÁSTROFE NARCÍSICA - PARA UMA COMPREENSÃO DA CLÍNICA CONTEMPORÂNEA / SHAME: THE REVELATION OF THE NARCISSISTIC CATASTROPHE - FOR AN UNDERSTANDING OF CONTEMPORARY CLINIC
Histery was used as model to express the typical form of psychic suffering of the end of century XIX. This thesis tries to justify the use of the melancholy as a psychic formation more adjusted to approach the form of the contemporary psychic suffering. For this a study on Freudian theory regarding the circumscription of this affection is undertaken. To demo

3. Etica no sistema de ideias de Noam Chomsky
This work opposes the hegemonic speech of the Quality, practiced in the great companies, to Noam Chomsky s perspective, in what concems to the crisis of values and the ethical problems that come in the relationship among the matter, the man, and the universal, that is wanted as liberal world. The research doesn t deny the efficiency of the methods and norms

4. RNA virus error catastrophe: Direct molecular test by using ribavirin
RNA viruses evolve rapidly. One source of this ability to rapidly change is the apparently high mutation frequency in RNA virus populations. A high mutation frequency is a central tenet of the quasispecies theory. A corollary of the quasispecies theory postulates that, given their high mutation frequency, animal RNA viruses may be susceptible to error c

5. On the translational error theory of aging
Theoretical treatments of error feedback in translation have revealed that two different modes of behavior are possible, depending on the values of certain parameters. In mode I, the error frequency will rise steadily toward randomness, inevitably reaching whatever value is catastrophic for cell survival; the “error catastrophe” theory of aging implicitl

6. Protein synthetic errors do not increase during aging of cultured human fibroblasts.
To test the error catastrophe theory of aging we determined the error frequency of protein synthesis in several strains of cultured human fibroblasts at early and late passage. Error rates were calculated from analysis of native and substituted actins on two-dimensional gels of cellular proteins after induction of mistranslation by histidine starvation in th

7. Denaturation: An Example of a Catastrophe
We show that a “phase diagram” for the conformational states of proteins can be constructed using the mathematical theory of singularities of functions developed recently by René Thom. For proteins subjected to the disruptive influences of temperature and/or concentration of denaturing agent, this theory can be used as a predictive tool to account for t
