13. Evaluation of material properties and design requirements for biodegradable magnesium stents
Magnesium represents a very attractive material for biodegradable stents since the process of its natural and gradual dissolution into the human body by a corrosion process would prevent restenosis risks and would allow the progressive transmission of the mechanical load to the surrounding tissues after several months of service. The objective of the present

14. A recontextualização do conhecimento científico: os desafios da constituição do conhecimento escolar
`This research consists in an empirical study which considers a mixed method of investigation, associating quantitative and qualitative aspects when approaching the investigation issues. Its theme is the school knowledge of Sciences and its concern is related to the transformations that occur in the official pedagogical discourse, specifically concerning the

15. Foliculogênese, maturação nuclear e citoplasmática de oócitos bubalinos - Bubalus bubalis : uma análise estrutural
The rusticity and milk production with high market value make possible to buffalos be bred in low or highly technified production system. On the other way, some species inherent characteristics make difficult to apply reproductive biotechniques to multiply animals (mainly females) with high genetic potential. Considering this, the present research establishe

16. Sistema de codificação de video baseado em transformadas tridimensionais, rapidas e progressivas / Video coding system based on three dimensional, fast and progressive transforms
The research on video coding systems has always been looking for techniques that can reach the highest possible compression rate. This compression rate increase is generally achieved by means of increased coding complexity, which is supported by the continuous increase verified in computational power. However, in some video coding and transmission situations

17. Dynamic bandwidth allocation for EPON networks / Alocação dinâmica de largura de banda em redes EPON
Telecommunication networks are divided into core, metropolitan and access networks. The core and metropolitan networks use high capacity bandwidth optical fibers, while the access networks have bandwidth bottlenecks because of the use of twisted-pair wires and coaxial cable. To solve this problem and to offers the users broadband access at low cost the use o

18. TRANSMISSÃO PROGRESSIVA DE MAPAS BASEADA EM GIS SERVICES / TRANSMISSION SCHEDULE OF MAPS BASED ON GIS SERVICES
A Internet criou um ambiente adequado para o compartilhamento de dados geoespaciais, permitindo aos usuários a transferência, visualização, manipulação e interação com esses dados. Esse ambiente não apenas fornece novas oportunidades na utilização dos dados espaciais, como também introduz novos problemas que devem ser resolvidos a fim de possibil

19. O perfil psicossocial do usuario do teste preditivo para a doença de Huntington e as ataxias espinocerebelares / The psychological profile of predictive test users for Huntington s disease and spinocerebellar ataxias
Recent advances in molecular genetics have made it possible to detect specific genetic alterations that are responsible for several diseases, even before the individual presents any symptoms. Hence, genetic tests such as the diagnostic test (DT) to confirm diagnosis and the predictive test (PT) or presymptomatic test can be performed. This study deals with t

20. Regional patterns of the temporal evolution of the AIDS epidemic in Brazil following the introduction of antiretroviral therapy
We examined the characteristics of the AIDS epidemic in the northeastern region of Brazil, comparing it to the epidemic in Brazil as a whole, and to the state of São Paulo, with respect to the temporal evolution of morbidity and mortality during the period 1990 to 1999, using information from communicable disease reports and mortality records. Since 1996, t

21. Estudo comparativo de algoritmos de compressÃo de imagens para transmissÃo em redes de computadores / Comparative study of algorithms of image compression for transmission in computer networks
Recentemente, foram desenvolvidos algoritmos iterativos de compressÃo destinados à transmissÃo de imagens estÃticas via rede tais como: JPEG progressivo, JPEG2000 progressivo, PNG entrelaÃado e GIF entrelaÃado. Esses algoritmos decompÃem a imagem e a transmitem de forma nÃo seqÃencial. O propÃsito desta dissertaÃÃo consiste em efetuar um estudo c

23. The pharmacological effect of Bothrops neuwiedii pauloensis (jararaca-pintada) snake venom on avian neuromuscular transmission
The neuromuscular effects of Bothrops neuwiedii pauloensis (jararaca-pintada) venom were studied on isolated chick biventer cervicis nerve-muscle preparations. Venom concentrations of 5-50 µg/ml produced an initial inhibition and a secondary increase of indirectly evoked twitches followed by a progressive concentration-dependent and irreversible neuromuscul

24. The impact of Chagas disease control in Latin America: a review
Discovered in 1909, Chagas disease was progressively shown to be widespread throughout Latin America, affecting millions of rural people with a high impact on morbidity and mortality. With no vaccine or specific treatment available for large-scale public health interventions, the main control strategy relies on prevention of transmission, principally by elim
