25. Descrição comparativa de aspectos fonetico-acusticos selecionados da fala e do canto em portugues brasileiro
In this dissertation three acoustic phonetic aspects were selected in order to compare speech to singing. The selected aspects were temporal structure, formant pattem and coproduction between consonants and vowels; and for each aspect a study has been elaborated, thus consisting the thesis the sum of this three studies. First we discuss the bad diction myth,

26. Analise de suspensões veiculares utilizando tecnicas de controle robusto
This thesis presents an analysis of the H IND. 2 e H IND. INFINITO robust control theory via linear matrix inequalities, and an approach by Youla parametrization of the closed loop transfer matrix, applied to the design of three different vehicular suspension models. The focus is on comparative analyses of the techniques employed rather than on a specific pr

27. Trade-off between age of first reproduction and survival in a female primate
Trade-offs are central to life-history theory but difficult to document. Patterns of phenotypic and genetic correlations in rhesus macaques, Macaca mulatta—a long-lived, slow-reproducing primate—are used to test for a trade-off between female age of first reproduction and adult survival. A strong positive genetic correlation indicates that female macaque

28. Emergent trade-offs and selection for outbreak frequency in spatial epidemics
Nonspatial theory on pathogen evolution generally predicts selection for maximal number of secondary infections, constrained only by supposed physiological trade-offs between pathogen infectiousness and virulence. Spread of diseases in human populations can, however, exhibit large scale patterns, underlining the need for spatially explicit approaches to path

29. Experimental manipulation of female reproduction reveals an intraspecific egg size-clutch size trade-off.
A negative relationship, or trade-off, between egg size and clutch size is a central and long-standing component of life-history theory, yet there is little empirical evidence for such a trade-off, especially at the intraspecific level. Here, I show that female zebra finches (Taeniopygia guttata) treated chronically during egg formation with the anti-oestrog

30. Trade-offs in the evolution of virulence in an indirectly transmitted macroparasite.
The adaptive trade-off theory for the evolution and maintenance of parasite virulence requires that virulence be genetically correlated with other fitness characteristics of the parasite. Many theoretical models rely on a positive correlation between virulence and transmissibility. They assume that high parasite replication rates are associated with a high p

31. Experimental Examination of Bacteriophage Latent-Period Evolution as a Response to Bacterial Availability
For obligately lytic bacteriophage (phage) a trade-off exists between fecundity (burst size) and latent period (a component of generation time). This trade-off occurs because release of phage progeny from infected bacteria coincides with destruction of the machinery necessary to produce more phage progeny. Here we employ phage mutants to explore issues of ph
