14. Da indeterminação a invariancia : considerações sobre morfologia musical a partir de peças de carater aberto / From indeterminacy to invariance : considerations about musical pmorphology from opera form works
The aim of this research was to propose a transference of the indeterminacy issue to the musical morphology field. By evaluating musical works classified as indeterminated in respect of their openess to varied interpretations, we realized that the definition of a musical work in the terms of flexibility or strictness highly depends on how its morphological c

18. Exposição e reatividade do prematuro ao ruído intenso durante o cuidado em incubadora / The Preterm babiesexposition and reactivity at the intense noise during care in incubators.
Introduction: The sound levels found in incubators and the additional noise generated during the manipulation of them reveal that the preterm and high-risk newly born babies (RN) are exposed to a noisy environment and are kept for long periods in this environment without chance to have auditive rest. Objectives: To evaluate the exposition of premature babies

21. MECHANISM, BEHAVIOR AND EVOLUTION OF CALLING IN FOUR NORTH AMERICAN TREEFROGS / Mecanismos de produção de som em anfíbios norte americanos: biomecânica, comportamento e evolução
Acoustic communication in frogs is an important model system for the study of behavioral evolution in vertebrates. This study aimed to extend the current model on the mechanism of calling in frogs in order to strengthen the bridge between behavioral and physiological knowledge in the field. The limits and tradeoffs of sound production by the passive larynx w

24. Accessory pathway for sound transfer in a neotropical frog.
A portion of the lateral body wall overlying the lung cavity of the arboreal frog, Eleutherodactylus coqui, vibrates in response to free-field sound. Peak displacement amplitude of the body wall in response to a natural call note presented at 73 decibels sound pressure level is 1.70 X 10(-9) m, roughly 8 decibels less than that of the ipsilateral eardrum, as
