Ensino a distância com recurso a MOOC para a capacitação ambiental
Miranda, Sandra; Almeida-Silva, M.; Sarreira, Pedro; Camus, Cristina Inês; Monteiro, Ana; David, Alexandra; Manteigas, Vítor; Abreu, RenatoO contínuo desenvolvimento das tecnologias de informação e comunicação (TIC) reorganizaram o modo como vivemos, comunicamos e aprendemos. Para as instituições de ensino superior, as TIC potenciaram o crescimento das modalidades do ensino a distância e a abertura de novos ambientes de aprendizagem, com recurso à educação digital. Como exemplo, os MOOC ganharam protagonismo a partir do movimento da educação abert...
Indoor air quality assessment in grocery stores
Baptista, Teresa; Almeida-Silva, M.; Silva, Dário; Diogo, Carlos; Canha, NunoIndoor Air Quality (IAQ) is a public and occupational health concern, as we are exposed to air pollutants daily given that we spend a great amount of our time in indoor environments. IAQ can be affected by numerous factors, from outdoor pollutants that get indoors through ventilation to building materials, furnishings, and activities carried by the building occupants. Exposure to air pollutants has been linked ...
Cytotoxicity assessment of nanoplastics and plasticizers exposure in in vitro l...
Clérigo, Fabiana; Ferreira, Sandra; Ladeira, Carina; Marques-Ramos, Ana; Almeida-Silva, M.; Mendes, L. A.Emerging contaminants such as nanoplastics (NPs), as well as manufacturing by-products such as plasticizers, have gained global attention and concern due to their limited biodegradability and their potential impact on human health, in particular the effects on respiratory tissue. In parallel, in vitro cell culture techniques are key to the assessment and characterization of toxic effects and cellular mechanisms...
Sustainable and active program – Development and application of SAVING methodology
Almeida-Silva, M.; Monteiro, A.; Carvalho, A.; Teixeira, A. M.; Moreira, J.; Tavares, D.; Tomás, T.; Coelho, A.; Manteigas, V.The SAVING project aimed to create a sustainable and active aging program to promote the transition to sustainable aging in residential structures for the elderly (RSEs), developing research activities to apply the best strategies and good practices regarding the promotion of an active, healthy, and sustainable aging regarding social, economic, environmental, and pedagogic aspects. All this innovative methodolo...
Assessment of particulate matter levels and sources in a street canyon at Loure...
Almeida-Silva, M.; Canha, N.; Vogado, F.; Baptista, P.C.; Faria, A.V.; Faria, T.; Coutinho, J.T.; Alves, C.; Almeida, S.M.Air quality in urban environments is directly related to structural aspects of streets and traffic variables, justifying the need for local assessments. This information is crucial as input to obtain accurate and reliable statistical modelling of the implementation of different mitigation scenarios aiming to improve the local air quality management. The present study intended to assess temporal trends of partic...
Sustainable and active ageing: Development and application of saving methodology
Almeida-Silva, M.; Manteigas,V.; Tavares, D.; Teixeira, A. M.; Carvalho, A.; Moreira, J.; Tomás, T.; Monteiro, A.; Viegas, C.SAVING project intends to develop research activities applying the best strategies and good practices regarding to the promotion of an active, healthy and sustainable ageing in relation to social, economic, environmental and pedagogic aspects. This project aims to create a Sustainable and Active Ageing Program named SAVING Program to promote the transition to a sustainable ageing in Elderly Care Centres (ECCs)....
Exposure and dose assessment to particle components among an elderly population
Almeida-Silva, M.; Almeida, S. M.; Pegas, P. N.; Nunes, T.; Alves, C. A.; Wolterbeek, H. T.People spend the majority of their time indoors and the composition and toxicity of indoor particles is very complex and present significant differences comparing with outdoor aerosols. Consequently, ambient particles cannot represent a real exposure. The aim of this work was to determine the daily exposure and the daily inhaled dose to particle components of elders living in Elderly Care Centers. A questionnai...
The application of a multi-wavelength Aethalometer to estimate iron dust and bl...
Fialho, Paulo; Cerqueira, Mário; Pio, Casimiro; Cardoso, João; Nunes, Teresa; Custódio, Danilo; Alves, Célia A.; Almeida, S. M.; Almeida-Silva, M.The two-component model (Fialho et al., 2006) was used to decouple the contributions of black carbon (BC) and iron oxides, present in dust, to the aerosol attenuation coefficient, measured with a multiwavelength Aethalometer. The model results were compared with the elemental carbon (EC) and iron concentrations determined in the laboratory from the analysis of aerosol particles collected with conventional sampl...

Characterization of the aeolian aerosol from Cape Verde by k 0-INAA and PIXE
Almeida-Silva, M.; Almeida, S. M.; Cardoso, J.; Nunes, T.; Reis, M. A.; Chaves, P. C.; Pio, C. A.Due to its location on West Coast of Africa, Cape Verde is highly influenced by Sahara Desert dust events being an optimum place to observe and study the African aeolian aerosol. During 2011, particulate matter with an aerodynamic diameter lower than 10 μm (PM10) was sampled in Santiago Island and its chemical composition was evaluated by k 0-instrumental neutron activation analysis (k0-INAA) and particle induc...
