Self-organized cyber-physical conveyor system using multi-agent systems
Leitão, Paulo; Barbosa, José; Funchal, Gustavo Silva; Melo, VictóriaThe adoption of industrial cyber-physical systems is facing several challenges, with artificial intelligence and self-organization techniques assuming critical aspects to be considered in the deployment of such solutions to support the dynamic evolution and adaptation to condition changes. This paper describes the implementation of a modular, flexible and self-organized cyber-physical conveyor system build up w...
Caracterização do salpicão do Planalto Mirandês
Martins, Conceição; Estevinho, Leticia M.A norte de Portugal, a designação genérica de salpicão, produto apreciado da salsicharia tradicional, e utilizada para designar um enchido volumoso, curado pelo fumo, variando na matéria prima, condimentação e tecnologia utilizada segundo a região de produção. Assim, onde existe a produção de vinho, este surge coma principal constituinte da condimentação, rareando ou sendo mesmo substituído por água nas zonas p...
Steroids in natural matrices: Chemical features and bioactive properties
Barreira, João C.M.; Ferreira, Isabel C.F.R.Since the establishment of their structure, the potential of steroids to act as structural cornerstone for the design of derived drugs became evident. This potential was confirmed by pharmacological studies, which highlighted broad biological effects. Nevertheless, the term steroid is commonly associated with androgenic-anabolic compounds, but the latter compounds comprise only a single, relatively small, class...
Aspectos bioquimicos y bioactivos de catorce accesos de tomate (Solanum lycoper...
Montoya, CésarEl tomate es uno de los vegetales más consumidos en el mundo y es el componente más importante de la dieta mediterránea. Hoy en día los consumidores son cada vez más conscientes y están mejor informados acerca de los beneficios a la salud que proporcionan los alimentos más allá de su función nutricional básica. Los principales compuestos del fruto de tomate son: carotenoides (β-caroteno y licopeno), vitaminas (...

Fernandes, Florbela P. (Ed.); Torres, Helena (Ed.); Pinto, Pedro (Ed.)These are the abstracts of the 4th Symposium of Applied Science for Young Researchers – SASYR. This scientific event welcomed works by junior researchers on any research topic covered by the following three research centers: ADiT-lab (from IPVC, Instituto Politécnico de Viana do Castelo), 2Ai (from IPCA, Instituto Politécnico do Cávado e do Ave) and CeDRI (from IPB, Instituto Politécnico de Bragança). The main ...
Stressed-out symbiosis: monitoring biodiversity through chemical fingerprints
Mota, Íris Alves; Pedro, Luís G.; Sousa, Maria João; Sánchez-Sánchez, JoséMonitoring through secondary metabolites as essential oils is informative on both plant states and their living conditions. Our research examined the effect of an abiotic factor (mild water stress) on a specific plant species (Ocimum basilicum L.). This drought condition was tested with plants inoculated with a symbiotic fungus (Glomus intraradices), to check if it ameliorated, in terms of biomass, the conseque...
Colaboração em ambientes online na resolução de tarefas de aprendizagem
Miranda, Luísa; Morais, Carlos; Dias, PauloNuma sociedade em permanente mudança, com transformações profundas quer nas concepções de aprendizagem e construção das representações de conhecimento, quer na sua aplicação em situações reais e profissionais, surge uma enorme necessidade de aprofundar a compreensão dos processos de aprendizagem colaborativa a partir dos ambientes online, os quais pelas suas potencialidades são meios poderosos para o desenvolvi...
Experimental optimization of hydraulic mini-turbines
Farrero, BernardoThe use of technologies to obtain energy from renewable sources has developed extensively over time and some of them are consolidated, such as hydroelectric power plants and wind turbines. On the other hand, there are still areas with a lot to increase and that has great potential. One of the energy sources is water. Hydroelectric is one of the main renewable generators of. However, there are still areas of tec...
Caracterização dos sedimentos produzidos por simulação de chuva sobre a banda á...
Fonseca, Felícia; Figueiredo, Tomás de; Moreira, Eduardo; Geraldes, Ana MariaA qualidade da água e o estado trófico das albufeiras são o resultado da interacção de factores intrínsecos e extrínsecos ao sistema. Entre os primeiros, salientam-se a idade e a morfologia das albufeiras. Em relação aos segundos são de realçar as características dos solos, climáticas, geológicas e morfológicas da bacia de drenagem. A ocorrência de fenómenos de erosão nas bacias de drenagem e na banda árida (zo...
Functional evaluation of patients undergoing hemodialysis with chronic kidney d...
Novo, André; Teixeira, Fernanda de Souza; Múrua, Aldo; Azevedo, José; Alves, Maria José; Paz Fernández, José António de; Travassos, FranciscoThe chronic kidney disease (CKD) is characterized by the loss of the kidney’s ability to eliminate toxic substances, concentrate urine and conserve electrolytes, with subsequent alteration of the remaining kidney function. The severe loss of kidney function is a first-order threat to life and requires the removal of toxic waste that cannot be debugged with sufficient effectiveness for other organ systems, as we...
