13. Benefícios sociais e ambientais do coprocessamento de pneus inservíveis: estudo de caso na cidade de João Pessoa-PB
The useless tire is a residue that must be managed correctly until its final disposal as well as its collection and storage must be done adequately. Therefore, if it is inadequately disposed of, it can cause damages to the environment and to public health. In March 2005 the city of João Pessoa, initiated a program called Programa Nordeste Rodando Limpo - No

15. Ambiente de apoio ao desenvolvimento de aplicações distribuídas e reconfiguráveis utilizando agentes de busca e classificação inteligentes / Environment to aid the development of distributed and reconfigurable applications using software agents to intelligent search and classification
Software engineering area suffered many transformations since its creation. Usually seen as a technique to raise productivity and decrease costs, softwares reusing is one of the main studies in computer field. Since softwares reconfiguration is, in essence, a software reuse, although with some adaptations, this work aims to develop a methodology and a set of

22. Reutilização de efluente de tingimentos de fibras acrílicas pós-tratamento fotoeletroquímico
On a laboratory scale effluents were produced from bichromic dyeing of acrylic fabrics with the basic dyes Blue Astrazon FGGL 300% and Yellow Gold Astrazon GL 200%. The residual dyeing baths were subjected to a photoelectrochemical treatment and reused in a second dyeing process. In the reutilization study, dyeings with treated effluent were compared with st
