Plastics in Agriculture - the Problem and One Potential Solution
Cansado, Isabel; Mourão, Paulo; Nabais, João; Castanheiro, JoséFor years, increased agricultural production and food quality has forced the increasing use of plastics in various activities. Currently, the plastic waste that results from the agricultural activity is recycled outside Portugal which increases the ecological footprint associated with the life cycle of these materials. It is crucial to consider new models for their valorisation at a local and regional level and...

Trindade, Sofia; Rouxinol, Maria Inês; Nabais, João; Agulheiro-Santos, Ana CristinaNowadays there is a search for new alternatives to replace harsh and expensive chemical methods to wastewater treatments. The common methods include the usage of chemicals that negatively affect the environment and the human health. The cladodes of Opuntia ficus-indica (L.) Mill have a great potential for use in innovative, cheap, renewable and eco-friendly water treatment due to their flocculant properties. In...
PORT COMMUNITY SYSTEMS (PCS) AND PORT PERFORMANCE
Caldeirinha, Vitor Manuel dos Ramos; Felício, José Augusto; Salvador, Antônia Sena; Nabais, João; Pinho Escola, TiagoThis study aims to evaluate the port community system (PCS) effect and its influence in port performance. In the Portuguese case, the port single window (JUP) is evaluated, with which it is identified. It was used analysis of the main components and the structural equation modeling (SEM) methodology, applied to the sample of 153 valid responses, obtained in the Portuguese port community. The results show differ...

The impact of Port Community Systems (PCS) characteristics on performance
Caldeirinha, Vítor; Felício, J. Augusto; Salvador, Antónia Sena; Nabais, João; Pinho, TiagoThe purpose of this study is to assess the effect of the port community system (PCS) and its influence on port performance. The techniques of principal component analysis and structural equation modelling are applied to 153 valid responses from a sample, obtained from Portuguese port community experts. The results identify and measure the factors that characterize the PCS and affects port performance. PCS chara...
