Aspect oriented pluggable support for parallel computing
Sobral, João Luís Ferreira; Cunha, Carlos A.; Monteiro, Miguel PessoaIn this paper, we present an approach to develop parallel applications based on aspect oriented programming. We propose a collection of aspects to implement group communication mechanisms on parallel applications. In our approach, parallelisation code is developed by composing the collection into the application core functionality. The approach requires fewer changes to sequential applications to parallelise th...
Reusable aspect-oriented implementations of concurrency patterns and mechanisms
Sobral, João Luís Ferreira; Cunha, Carlos A.; Monteiro, Miguel PessoaIn this paper, we present a collection of well-known high-level concurrency patterns and mechanisms, coded in AspectJ. We discuss benefits of these implementations relative to plain Java implementations of the same concerns. We detect benefits from using AspectJ in all the cases presented, in the form of higher modularity, reuse, understandability and unpluggability. For most of the implementations, two alterna...
The isolation and characterization of cytochrome c nitrite reductase subunits (...
Almeida, Maria Gabriela; Macieira, Sofia; Gonçalves, Luisa L.; Romão, Maria J.; Costa, Cristina; Lampreia, Jorge; Moura, José J. G.; Moura, IsabelEur. J. Biochem. 270, 3904–3915 (2003) doi:10.1046/j.1432-1033.2003.03772.x ; The cytochrome c nitrite reductase is isolated from the membranes of the sulfate-reducing bacterium Desulfovibrio desulfuricans ATCC 27774 as a heterooligomeric complex composed by two subunits (61 kDa and 19 kDa) containing c-type hemes, encoded by the genes nrfA and nrfH, respectively. The extracted complex has in average a 2NrfA:1...

Cytochrome c nitrite reductase from desulfovibrio desulfuricans ATCC 27774
Moura, Isabel; Cunha, Carlos A.; Macieira, Sofia; Dias, João M.; Almeida, Gabriela; Gonçalves, Luisa L.; Costa, Cristina; Lampreia, Jorge; Huber, RobertThe Journal of Biological Chemistry Vol. 278, No. 19, Issue of May 9, pp. 17455–17465, 2003 ; The gene encoding cytochrome c nitrite reductase(NrfA) from Desulfovibrio desulfuricans ATCC 27774 was sequenced and the crystal structure of the enzyme was determined to 2.3-Å resolution. In comparison with homologous structures, it presents structural differences mainly located at the regions surrounding the putativ...
