13. Territoires de l Oubli : Continuum, Process and listening - a performance conception / Continuum, Processo e Escuta em Territoires de l Oubli : concepção de uma interpretação
This thesis connects theoretical framework to interpretative perspective. It discusses Spectral Music in the context of piano performance. This research aimed to develop an interpretative conception for Tristan Murail?s Territoires de l´Oubli. Three aspects were studied along this goal: incorporation of the Continuum notion, study of the Process idea and th

14. Association study between a genetic polymorphism in aldosterone sinthase and resistance to anti-hypertension treatment / Estudo de associação entre polimorfismo no gene da aldosterona sintase e resistencia ao tratamento anti-hipertensivo
Introduction: Resistant hypertension is characterized by elevated blood pressure concurrent with the use of 3 different anti-hypertensive drugs, being one of them a diuretic. There are genetic factors that interfere in the arterial pressure control system and may have a significant role in resistant hypertension. Renin-Angiotensin-Aldosterone System plays a

15. Controle de síntese sonora por analogia acústica e semântica aplicando computação bio-inspirada / Control of sound synthesis by acoustic and semantic analogy using bio-inspired computing
Este trabalho sugere novos paradigmas de controle de mecanismos de síntese sonora. Utilizando conceitos das ciências cognitivas, o processo gerativo é modelado como um sistema de conversões entre representações, da atuação subjetiva do usuário, passando pela descritiva e culminando no material sonoro. A partir do estudo da analogia descritiva, engen

16. Wheat plants response to new endophytes, achromobacter and zoogloea, under field conditions / Resposta da cultura do trigo aos novos endófitos, Achromobacter e Zoogloea, em condições de campo
This study reports for the first time the endophytic nature of Achromobacter and Zoogloea in wheat plants, that were identified by 16S rDNA gene sequence analyses. To find out the localization of the bacterial cells (IAC-AT-8- Azospirillum brasiliense, IACHT- 11- Achromobacter insolitus, IAC-HT-12- Zoogloea ramigera) in/on wheat plants, an experiment was set

17. Comparison of some mechanical models of larynx in the synthesis of voiced sounds
The process of voiced sounds production can be described as follows: air coming from the lungs is forced through the narrow space between the two vocal folds, which are set in motion in a frequency governed by the tension of their tissues. The vocal folds change the continuous flow that comes from the lungs into a series of pulses. Then, as the flow passes t

18. Sintese e reconhecimento da fala humana / Synthesis and recognition of human speech
The goal of this dissertation is to review the main concepts relating to the synthesis, processing, and recognition of human speech by computer. These technologies have many applications, which have increased substantially in recent years after the spread of portable communication equipment (mobile phones, laptops, palmtops) and the universal access to the I

19. Sintese sonora auto-organizavel atraves da aplicação de algoritmos bio-inspirados / Self-organizing sound synthesis by means of the application of bio-inspired algorithms
Não há limitações teóricas para o uso do computador como fonte de sons musicais. O computador digital permite a produção de qualquer som concebivel dada a seqüência correta de números (amostras digitais). No entanto, produzir uma dada seqüência de números que corresponda a um som musical que possua determinadas características perceptivas desej

20. Desenvolvendo uma meta-linguagem para síntese sonora.
The software sound synthesis is closely related to the Music N programs started with Music I in 1957. Although theMusic N has many advantages such as the unit generators and a flexible score language, it presents a few problems like limitations on instrument reuse, in- flexibility of parameters, lack of a built-in graphical interface, and usually only one pa

21. POLYPHONIC SYNTHESIZER CONTROLLED BY MICROCOMPUTER / SINTETIZADOR POLIFÔNICO CONTROLADO POR MICROCOMPUTADOR
This work describes a system intendent to perform synthesis of four simultaneous sonds controlled by microcomputer using sustrative syntesis technique. Hardware employs analogical performing generating, filtering and conformative functions and performance in real time is allowed throug use of a Keyboard. Programming developed allows user to act upon those bl

22. Linguistic aspects of speech synthesis.
The conversion of text to speech is seen as an analysis of the input text to obtain a common underlying linguistic description, followed by a synthesis of the output speech waveform from this fundamental specification. Hence, the comprehensive linguistic structure serving as the substrate for an utterance must be discovered by analysis from the text. The pro

23. Bacterioplankton Secondary Production Estimates for Coastal Waters of British Columbia, Antarctica, and California
The principal objective of this study was to quantify the rate of heterotrophic bacterioplankton production. Production was estimated by two approaches: (i) measurement of increasing bacterial abundance with time in filtered (3-μm pore size) seawater and (ii) estimation of bacterial deoxyribonucleic acid synthesis by tritiated thymidine incorporation in unf
