A conceptual framework for higher education institutions and the circular economy
Gaspar, Marcelo Gaspar; Mateus, Dina; Galacho, Cristina; Dinis, Maria; Teixeira, Margarida; Viegas, Laura; Pardal, Ana; Manteigas, VítorThe need to investigate the knowledge and participation of Higher Education Institutions (HEIs) students in sustainability issues is crucial. The working group on Circular Economy and Waste Management from the Portuguese Sustainable Campus Network (RCS) is dedicated to investigating the attitudes and comprehension of HEIs students about the principles and practices of the Circular Economy (CE). This group inten...
Perceções e práticas dos estudantes do ensino superior português sobre economia...
Mateus, Dina; Galacho, Cristina; Dinis, Maria; Teixeira, Margarida; Viegas, Laura; Gaspar, Marcelo; Pardal, Ana; Manteigas, Vítor; Moreira, AnabelaAs Instituições de Ensino Superior (IES) têm um papel crucial na educação para a economia circular e gestão sustentável de recursos e resíduos (ECGSRR), cabendo-lhes assegurar a transmissão de conhecimento e valores aos estudantes, que serão os futuros profissionais e decisores. Neste contexto, a missão das IES inclui diagnosticar e enfrentar os desafios ambientais contemporâneos, oferecendo uma formação inovad...
Modeling and optimization of atmospheric CO2 capture for neutralization of high...
Madeira, Luís; Teixeira, Margarida; Carvalho, FátimaLab-scale stirrer bubble and lab-scale stepped continuous flow capillary columns were developed to neutralize lime precipitation treated slaughterhouse wastewater (SWW) and recover the volatilized ammonia, using atmospheric CO2. These experiments were carried out using central composite design based on the response surface methodology. The carbonation process occurred in both processes. For the bubbling process...
Immediate one-step lime precipitation and atmospheric carbonation as pre- treat...
Madeira, Luís; Teixeira, Margarida; Prazeres, Ana; Almeida, Adelaide; Chaves, Humberto; Carvalho, FátimaThe treatment of some industrial wastewaters is complex, since they usually contain complex non-biodegradable organic compounds or toxic compounds which are not easily treatable. These compounds are not removed by biological treatment in wastewater treatment plants and they may affect the removal of ammonium, nitrate, organic nitrogen by these treatment systems. Therefore, this research proposes a new and innov...
Innovations in sustainable agriculture: case study of Lis Valley irrigation dis...
Oliveira, Maria de Fátima; Gomes Da Silva, Francisco; Ferreira, Susana; Teixeira, Margarida; Damásio, Henrique; Ferreira, António DinisThe innovation of agricultural systems management is a determinant factor that guarantees adaptation to a new paradigm of global economy, environmental protection, and social requirements. The conventional concepts of innovation, applicable to new products and processes, do not consider many characteristics of the agricultural sector, such as social innovation and innovation resulting from new or renewed proces...
The role of human papillomavirus in head and neck tumors
Saraiva, Nadine; Rodrigues, Joana; Bonito, Nuno; Prazeres, Hugo; Cruz, Eugénia; Costa, Miguel; Teixeira, Margarida; Silva, Regina; Gervásio, HelenaThe human papillomavirus (HPV) infection is a risk factor for the development of tumors of the head and neck. We intend to assess the prevalence of HPV in these tumors in patients without alcohol and tobacco risk factors.The presence of HPV DNA was tested by PCR (Polymerase Chain Reaction) in all patients with head and neck tumor identified between 2010 and 2013.44 patients with a mean age of 61.4 years were id...
A Bioética e a investigação em células estaminais humanas: em Portugal e na Com...
Teixeira, Margarida; Oliveira, Clara CostaCom o presente trabalho, realizado no âmbito do Centro de Investigação em Educação, da Universidade do Minho, pretendemos refletir sobre as implicações éticas da investigação em células estaminais humanas. A investigação em células estaminais tem sido de extrema importância pois permite quer conhecer os processos de desenvolvimento dos organismos, quer encontrar formas de tratamento de doenças irreversíveis. Co...
Sirolimus ameliorates cyclosporin-induced nephrotoxicity in a rat model – focus...
Sereno, José; Romão, Ana M.; Teixeira, Margarida; Parada, Belmiro; Santos, Paulo R.; Alves, Rui; Mega, Cristina; Vala, Helena; Lemos, Edite T.Sirolimus (SRL) have been pointed as a feasible option for minimize the use of cyclosporine A (CsA), especially because os putatively less nephrotoxicity. However, the cellular mechanism underlying the renoprotection remains to be elucidated, and the clinical data is yet insufficient. This stuty aimed to characterize the histological lesions and the molecular pathways implicated in CsA-induced nephropathy and p...
