Potential of rainwater harvesting in the retail sector: a case study in Portugal
Ferreira, Ana; Sousa, Vítor; Pinheiro, Manuel Duarte; Meireles, Inês; Silva, Cristina Matos; Brito, Jorge de; Mateus, RicardoWater is a crucial resource for life, and it is increasingly scarce in many regions of the globe. In addition, retail water use is responsible for up to 19% of public water globally supplied. Hence, this study has set out to explore the technical and economic feasibility of rainwater harvesting systems as an alternative water source for a retail store located in southern Portugal. Water consumption data from 20...
Teachers’ appreciation of benefits and shortcomings of online and blended highe...
Skliarova, Iouliia; Meireles, Inês; Tchemisova, Tatiana; Cação, Isabel; Martins, NatáliaThis paper is devoted to identifying online teaching strategies appropriate for blended and face-to-face higher STEM (Science, Technology, Engineering, and Mathematics) education. The study is inspired by the experience gained during the COVID-19 pandemic lockdown, which forced many higher education institutions worldwide to shift abruptly to distance education and try many new tools, teaching methods, and stra...
Determinants of water loss in Portuguese utilities
Meireles, Inês; Sousa, Vitor; Matos, José Pedro; Cruz, Carlos OliveiraThis research aims to evaluate the main determinants of real water loss per unit length of the network in the Portuguese water sector, using data covering a 10-year period. The governance model, typology of the area, type of service, management model, total water conveyed, and total network length were found to be statistically significant determinants. The methodology employed Generalized Linear Models and Art...
Enriching traditional higher STEM education with online teaching and learning p...
Skliarova, Iouliia; Meireles, Inês; Martins, Natália; Tchemisova, Tatiana; Cação, IsabelIn this paper, we aim to identify online teaching and learning practices that would be beneficial for blended and traditional on-campus education within STEM (Science, Technology, Engineering, and Mathematics) courses. Our university, as well as the majority of higher education institutions worldwide, has had few to no experience in delivering full online courses before 2020. The teaching process was, however, ...
Assessing the Inclusion of Water Circularity Principles in Environment-Related ...
Miranda, Ana Catarina; Fidélis, Teresa; Roebeling, Peter; Meireles, InêsCities face increasing water pressure and supply issues, jeopardizing the balance between growth and sustainable water resource use. Green, resilient, smart, circular, blue, water sensitive, or water-wise city concepts are increasingly part of the design of strategies to rethink cities. These concepts have motivated many studies, but little is known about their relative relevance among the scientific community ...
Life-cycle cost as basis to optimize waste collection in space and time: a meth...
Sousa, Vitor; Ferreira, Célia; Vaz, João M.; Meireles, InêsExtensive research has been carried out on waste collection costs mainly to differentiate costs of distinct waste streams and spatial optimization of waste collection services (e.g. routes, number, and location of waste facilities). However, waste collection managers also face the challenge of optimizing assets in time, for instance deciding when to replace and how to maintain, or which technological solution t...
