Short-term evolution of a reflective beach sector in front of a coastal lagoon ...
Gama, Cristina; Albardeiro, Luís; Jacob, José; Pinheiro, IsabelThe subaerial beache act as detritical barriers in the opening and closing of lagoons located in sandy coastal ares. The study of beach morphodynamics, considering the evolution of the beachface and the berm, in these cases is critical to coastal management. The studied area located in an embayed sandy coastline at the Portuguese Southwest Atlantic Coast, is a 308m long subaerial, coarse to very coarse, sandy b...
Short-term evolution of a reflective beach sector in front of a coastal lagoon ...
Gama, Cristina; Albardeiro, Luís; Jacob, José; Pinheiro, IsabelSeveral coastal lagoon entrances are controlled by the contiguous subaerial beach that works as a detrital barrier. Hence the importance of characterizing the adjacent beach morphodynamics regarding the beachface and berm reconstruction for coastal management proposals. The studied area, a subaerial beach sector of 308 m, located in front of the Melides coastal lagoon, is placed in an embayed sandy coastline a...
Erosion of rocky shores- protection promoted by sandy beaches and shore platforms
Moura, Delminda; Gabriel, Selma; Jacob, José; Fortes, Conceição; Silva, Paulo A.; Horta, João; Abreu, TiagoO sector costeiro do Algarve central entre as praias da Galé e Olhos de Água deve a sua fisiografia crenulada a um sistema cársico bem desenvolvido em rochas carbonatadas. As arribas possuem no sopé uma plataforma litoral rochosa ou uma praia arenosa. Os principais objectivos do projecto de investigação EROS são: (i) a quantificação da dissipação da energia das ondas ao longo de plataformas litorais e de praias...
Coastal morphology along the Central Algarve rocky coast: driver mechanisms
Moura, Delminda; Gabriel, Selma; Jacob, JoséThe boundary between the mainland and the sea – the littoral fringe - crosses several sub-environments, among them, the rocky coasts whose evolution depends on marine and sub-aerial processes as well as on the rocks’ mass properties. The study area - in central Algarve (South Portugal) - is framed in a rocky coast exposing carbonate rocks. This work identifies the main drivers to the coastal morphology in that ...
Evolution of the Beach profile in response to storm incidence: Santo André beac...
Mota, Paul; Jacob, José; Gama, Cristina; Salgado, RuiThe study of storm events is essential to understand and predict the storm effects on beaches with implications for coastal management. The effect of the storm that occurred from 21st to 23rd October of 1999 on the Tróia-Sines embayed coast (TSEC) was analyzed in detail regarding the evolution of the Santo André beach profile. The wave climate was simulated using the SWAN wave model in a non-stationary mode, in...
Characterization of The wave field along the Tróia-Sines embayed coast during a...
Mota, Paul; Jacob, José; Gama, Cristina; Salgado, RuiThe study of storm events is essential to understand and predict their effects on sandy beaches with implications for coastal management. Erosion due to storms is responsible for large changes in the shape of the beach profiles. The main goal of this work is the characterization of the wave field along the Tróia-Sines Embayed Coast (TSEC) during a storm event that occurred from 20 to 25 October 1999. The wave p...
Shadowing effects on beach morphodynamics during storm events on Tróia-Sines em...
Jacob, José; Gama, Pereira; Salgado, Rui; Liu, James; Silva, Ana MariaThe prediction of storm effects on coastline is essential to coastal management and represents a critical issue for the scientific community discussion. In this paper we used SWAN and Méso-NH models to simulate the wave pattern along a ten’s kilometre-scale sandy coastline (TSEC, Tróia-Sines Embayed Coast). The obtained results indicate a shelter effect of the Espichel Cape in the northern half of the TSEC for ...
Transplante de Células-tronco marcadas para o miocárdio de paciente com doença ...
Jacob,José Luiz Balthazar; Salis,Fernando Vilela; Ruiz,Milton A.; Greco,Oswaldo TadeuO transplante de células-tronco é uma nova terapia com objetivo de produzir regeneração cardíaca pela diferenciação ou aumento dos miócitos cardíacos ou proliferação neovascular em pacientes no estágio final de insuficiência cardíaca congestiva secundária a cardiomiopatia dilatada¹, mas os resultados são desconhecidos2,3.
Pseudo-aneurisma do ventrículo esquerdo
Jacob,José Luiz Balthazar; Buzelli,Graziele; Machado,Nilton Carlos Spinola; Garzon,Pedro G. A.; Garzon,Sérgio A. C.A ruptura da parede livre do ventrículo esquerdo é uma dramática, porém nem sempre fatal complicação do infarto agudo do miocárdio. No entanto, se o diagnóstico correto for retardado, o tratamento cirúrgico pode ser comprometido. Os autores relatam um caso de volumoso pseudo-aneurisma de parede inferior de ventrículo esquerdo diagnosticado ao estudo angiográfico.
Implante direto de stent através de cateter guia 5F por técnica transradial
Coelho,Wilson Miguel Cecim; Jacob,José Luiz Balthazar; Araujo Filho,José Dalmo de; Frederico,Sumaira Faitarone; Cabbaz,Ivone Eduarda CamposOBJETIVO: Avaliar o implante de stents sem dilatação prévia com cateter balão convencional para o tratamento das obstruções coronarianas, utilizando-se cateteres guias de baixo perfil através da técnica radial. MÉTODOS: A técnica radial é atraente pela possibilidade de se evitar o trauma provocado pelo balão, menor tempo para sua realização, exposição reduzida à radiação e consumo de contraste em quantidades in...
