Water intensity indicators in the global retail sector
Ferreira, Ana; Pinheiro, Manuel Duarte; de Brito, Jorge; Mateus, Ricardo; Sousa, VitorRetail water use accounts for up to 19% of public water globally supplied. However, the water intensity of retail stores and its drivers remains largely unexplored. This study is the first of its kind to provide water intensity indicators for retail buildings, namely Water Intensity per store Area (WIA), Water Intensity per Store (WIS), Water Intensity per Worker (WIW) and Water Intensity per Revenue (WIR), pro...
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...
Experimental study on the wear behavior of B4C and TiB2 monolayered PVD coating...
Casais, Rafaela B.; Baptista, António Monteiro; Silva, Francisco J. G.; Andrade, Fátima; Sousa, Vitor; Marques, Maria JoséThere are several ways to characterize the wear resistance of coatings in the laboratory, almost all of them applying relatively low loads, both punctually and more widely. Pin-on-disc, reciprocal sliding, and micro-abrasion wear tests are quite common configurations for this purpose. Thus, a gap was identified in terms of characterization of hard PVD coatings subject to higher loads. This work aims to study an...
Increasing the Sustainability of Manufacturing Processes in Plastic Injection: ...
Costa, Rúben; Sousa, Vitor; Silva, Francisco J. G.; Campilho, Raul; Sá, José Carlos; Pinto, Arnaldo; Pereira, JoãoIn the 20th century, there was a burst concerning the development of the automobile industry, which has become an essential asset for society. With its evolution, this industry created a foundation that based its competitiveness on satisfying people’s needs with the highest possible quality and always respecting the delivery deadlines. With the growth in demand, the improvement of certain processes was needed t...
Dataset of socio-economic and waste collection indicators for Portugal at munic...
Oliveira, Verónica; Sousa, Vitor; Dias-Ferreira, CeliaThis data article presents demographic, socio-economic and waste-related data at municipal level for Portugal. The dataset includes raw data collected from 4 main sources: (i) the annual reports of waste management companies; (ii) the database of the Portuguese water, sanitation and waste regulatory entity; (iii) the Portuguese Environmental Agency; and (iv) national statistical data. Relevant indicators for wa...
Artificial neural network modelling of the amount of separately-collected house...
Oliveira, Verónica; Sousa, Vitor; Ferreira, CéliaThis work develops an artificial neural network (ANN) model using genetic algorithms to estimate the annual amount (kg/inhabitant/year) of separately-collected household packaging waste. The ANN model comprises one input layer, one hidden layer with seven neurons and one output layer. Ten variables affecting the amount of separately-collected packaging waste were identified and used in the ANN model. These vari...

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...
NMR metabolomics of human lung tumours reveals distinct metabolic signatures fo...
Rocha, Claudia M; Barros, Antonio S; Goodfellow, Brian J; Carreira, Isabel M; Gomes, Ana; Sousa, Vitor; Bernardo, Joao; Carvalho, Lina; Gil, Ana MLung tumour subtyping, particularly the distinction between adenocarcinoma (AdC) and squamous cell carcinoma (SqCC), is a critical diagnostic requirement. In this work, the metabolic signatures of lung carcinomas were investigated through 1H NMR metabolomics, with a view to provide additional criteria for improved diagnosis and treatment planning. High Resolution Magic Angle Spinning Nuclear Magnetic Resonance ...

Rocha, Claudia M.; Barros, Antonio S.; Goodfellow, Brian J.; Carreira, Isabel M.; Gomes, Ana; Sousa, Vitor; Bernardo, Joao; Carvalho, Lina; Gil, Ana M.NMR metabolomics of lung tissues revealed distinct metabolic signatures for adenocarcinomas and squamous cell carcinomas (the two types being discriminated with a 94% classification rate), thus showing potential for aiding tumours subtyping, a critical diagnostic requirement in lung cancer management.Lung tumour subtyping, particularly the distinction between adenocarcinoma (AdC) and squamous cell carcinoma (Sq...
