Overview of clams packaging systems sustainability
Carneiro, A.; Goes, C. B.; Mota, I.; Ferreira, R.; Cruz, A.; Marcos, Begonya; Sivertsvik, M.; Poças, F.Background: This work analyses the protection requirements and options for primary and transportation packaging of shellfish. It considers the properties of materials and the most recent developments and innovations in the arena created by legislation shaping packaging practices and frameworks of circularity and sustainability. A short review of the environmental profiles of typical packaging systems is provide...
Enhancing the Sustainability of Growing Media: Exploring Pine Bark as a Perlite...
Machado, R.A.M.; Dias, G.; Alves-Pereira, I.; Ferreira, R.Increasing the sustainability of growing media constituents is currently a priority. This study aimed to evaluate whether pine bark can replace perlite in coir-based substrates. For this purpose, an experiment was carried out with four treatments: two coir-based mixes, one containing perlite and the other pine bark, and two electrical conductivities of nutrient solution (1.5 ± 0.2 and 2.5 ± 0.2 dS m-1). Lettuce...
Influence of co-applying biochar, compost and inorganic nitrogen on growth, nut...
Machado, R.M.A.; Alves-Pereira, I.; Velez, D.; Grilo, A.; Ferreira, R.In the pursuit of sustainable vegetable farming methods, the effect of co-application of compost, biochar, and a reduced amount of inorganic nitrogen on growth and the quality of turnips was studied in a greenhouse pot experiment. The experiment was carried out with five treatments: unfertilized soil, compost + biochar, compost + 0.5g N/pot, biochar + 0.5 g N/pot, compost + biochar + 0.5 g N/pot. Municipal orga...
European territorial cooperation towards territorial cohesion?
Medeiros, E.; Scott, J.; Ferreira, R.; Boijmans, P.; Verschelde, N.; Guillermo-Ramírez, M.; Gyula, O.; Peyrony, J.; Soares, A.Understood in some conceptual analysis as a pillar of territorial cohesion and due to its critical role in promoting territorial integration, territorial cooperation is often presented as one of the major positive achievements of European Union (EU) Cohesion Policy. In this context, this article proposes a conceptual framework to assess the contribution of the European Territorial Cooperation process, including...
Ethylene removal by Ag-based ZSM-5 adsorbents for the preservation of climacter...
Ferreira, R.; Lopes, H.; Lourenço, J. P.; Silva, J. M.; João, I. M.; Ribeiro, M. F.; Fernandes, A.Ethylene removal is crucial for fruits and vegetables preservation because even a very low concentration (<0.1ppm) can induce ripening during storage and transportation. Ag+ exchanged ZSM-5 zeolites were investigated as adsorbents for the efficient removal of ethylene. Two ZSM-5 materials (Si/Al ratios of 15 and 40), with different amounts of Ag (up to 6 % by weight) and two compensating cations, Na+ and H+, we...
Acacia sp. bark: from waste to a nature-based solution for water treatment
Ferreira, R.; Coura, R. D.; Nunes, L.; Ferraz, A. I.; Rodrigues, A. C.Coagulation-flocculation is an important process in water treatment plants. Recent studies have shown the potential of condensed tannins for the production of coagulants of natural origin, as an alternative to chemical coagulants. The present study highlights the importance of the development of nature-based solutions that can be alternative to conventional processes and is focused on optimizing the process of ...
Brincar e desenvolvimento infantil dos 0 aos 3 meses
Festas, C.; Ferreira, R.Enquadramento: A criança, como ser em desenvolvimento, tem direito a que lhe sejam proporcionadas condições favoráveis a um desenvolvimento global, o mais harmonioso possível. Na primeira infância, dos 0 aos 3 anos, o desenvolvimento infantil é diretamente influenciado pela qualidade de vida da criança. Deste modo, é importante conhecer estratégias que sejam promotoras do melhor desenvolvimento infantil possíve...
Coir-Based Growing Media with Municipal Compost and Biochar and Their Impacts o...
Martins, T.C.; Machado, R.M.A.; Alves-Pereira, Isabel; Ferreira, R.; Gruda, N.S.The purpose of this study was to develop substrates with little or no peat by combining coir-based growing media with municipal compost and/or acacia biochar, two locally produced renewable resources, and to assess their effects on lettuce seedling emergence and growth, as well as their content in photosynthetic pigments and total phenols. Two experiments were carried out, the first with six mixes using compost...
Cardiac mitochondrial dynamics, autophagy and regeneration are stirred by doxor...
Brandão, S. R.; Reis-Mendes, A.; Neuparth, M. J.; Carvalho, F.; Ferreira, R.; Costa, V. M.Background: The chemotherapeutic agent doxorubicin (DOX) has been widely used in the treatment of solid tumors and hematological malignancies [1]. However, serious adverse side effects have emerged in patients treated with this drug, notably cardiotoxicity [2]. Moreover, aging is a risk factor for the development of cardiovascular diseases in cancer treated patients [3]. Objective: We herein aimed to evaluate t...
How can LMS affect student’s motivation and engagement?
Ferreira, R.; Cardoso, E.; Oliveira, J.Technology has revolutionized the education system. Many tools such as Learning Management Systems (LMS) were developed to enhance the learning process. With this new technology, teachers and universities can explore options otherwise difficult to implement. Keeping students engaged is one of the biggest challenges that educational institutions face. Students’ motivation, engagement, and performance can be affe...
