1. Simetria radial de soluções positivas de sistemas elípticos cooperativos / Radial symmetry of positive solutions of cooperative elliptic systems
Neste trabalho estudamos a questão de simetria de soluções positivas de equações e sistemas de equações diferenciais parciais. Descrevemos em detalhe a demonstração de dois resultados sobre simetria radial, um para equações em domínios limitados e outro para sistemas de equações no espaço todo. Ambas as demonstrações baseiam-se no método do

2. Uma alternativa a inundação baseada em tabelas de dispersão para planos de controle de redes opticas / A hash table based flooding alternative for optical networks control plane
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Servi

3. Management of complete ureteral obstructions with a transluminal puncture technique
INTRODUCTION: The traditional delayed treatment of iatrogenic complete ureteral obstruction is open surgery. An easy endourological technique, transluminal re-canalization of the ureter by guide-wire puncture under fluoro-endoscopic control, which has been performed on 4 patients, is described. SURGICAL TECHNIQUE: With the guidance of C-arm fluoroscopy, by m

4. Magnetic resonance imaging planes for the 3-dimensional characterisation of human coronary arteries.
We report a magnetic resonance imaging study which developed a consistent hierarchy of imaging planes for examination of the origins, courses and principal branches of the main coronary arteries of prepared human cadaveric hearts. The reference longitudinal axis was chosen between the aortic valve and the apex of the left ventricle. A series of transverse pl

5. Dipyridamole magnetic resonance imaging: a comparison with thallium-201 emission tomography.
Limitation of space and motion artefact make magnetic resonance imaging during dynamic exercise difficult. Pharmacological stress with dipyridamole can be used as an alternative to exercise for thallium scanning. Forty patients with a history of angina and an abnormal exercise electrocardiogram were studied by dipyridamole thallium myocardial perfusion tomog
