D3S: Decision support system for sectorization
Öztürk, E. G.; Rocha, P.; Rodrigues, A. M.; Ferreira, J. S.; Lopes, C.; Oliveira, C.; Nunes, A. C.Sectorization problems refer to dividing a large set, area, or network into smaller parts concerning one or more objectives. A decision support system (DSS) is a relevant tool for solving these problems, improving optimisation procedures, and finding feasible solutions more efficiently. This paper presents a new web-based Decision Support System for Sectorization (D3S). D3S is designed to solve sectorization pr...
Parcel delivery services: A sectorization approach with simulation
Lopes, I.; Rodrigues, A.; Ozturk, E.; Ferreira, J.; Nunes, A. C.; Rocha, P.; Oliveira, C.Sectorization problems, also known as districting or territory design, deal with grouping a set of previously defined basic units, such as points or small geographical areas, into a fixed number of sectors or responsibility areas. Usually, there are multiple criteria to be satisfied regarding the geographic characteristics of the territory or the planning purposes. This work addresses a case study of parcel del...

Silva, R.; Sousa, G.; Brochado, G.; Rocha, P.; Coelho, A.; Lopes, S.As Lesões Músculo-Esqueléticas Relacionadas com o Trabalho foram consideradas pela Organização Mundial de Saúde como uma doença de saúde pública. Estudos realizados até ao momento indicam que a tendência da prevalência de incapacidades associadas a estas lesões, venha a aumentar nos próximos anos sendo que, as regiões anatómicas que reportam sintomatologia associada ao trabalho e que por sua vez poderá criar in...
Comparison of a variety of physico-chemical techniques in the chronological cha...
Silva, Ana Catarina; Rocha, P.; Antelo, J.; Valderrama, P.; Lopez, R.; Geraldo, Dulce; Proenca, M. F.; Pinheiro, J. P.; Fiol, S.; Bento, M. FátimaThe degree of stability and maturity of the organic matter are fundamental features of the chemical characterization of compost. These characteristics are related to the extensive formation of aromatic structures and of oxygen-containing functional groups. The increase of the amount of these chemical moieties can be assessed by different analytical methodologies, based on thermal, spectrophotometric, and electr...
An application of Preference-Inspired Co-Evolutionary Algorithm to sectorization
Öztürk, E.; Rocha, P.; Sousa, F.; Lima, M.; Rodrigues, A. M.; Ferreira, J. S.; Nunes, A. C.; Lopes, C.; Oliveira, C.Sectorization problems have significant challenges arising from the many objectives that must be optimised simultaneously. Several methods exist to deal with these many-objective optimisation problems, but each has its limitations. This paper analyses an application of Preference Inspired Co-Evolutionary Algorithms, with goal vectors (PICEA-g) to sectorization problems. The method is tested on instances of diff...
Comparison of cadmium binding by humic and fulvic acids extracted from compost ...
Rocha, P.; Silva, Ana Catarina; Antelo, J.; Bento, M. Fátima; Bettencourt, Ana Paula; Fiol, S.; Geraldo, Dulce; López, R.; Macías, F.; Pinheiro, J. P.Compost is a bio-sustainable material produced by the controlled decomposition of the organic wastes. Composting can be employed for the urban organic waste treatment in alternative to incineration or landfill disposal [1]. The properties of compost are closely related to the presence of humic-like substances (HS). Both fulvic acids (FA) and humic acids (HA) contain a significant amount of carboxylic acids and ...
Comparison of cadmium binding by humic and fulvic acids extracted from two comp...
Silva, Ana Catarina; Rocha, P.; Antelo, J.; Bento, M. Fátima; Bettencourt, Ana Paula; Fiol, S.; Geraldo, Dulce; López, F.; Macías, F.; Pinheiro, J. P.Composting has been proven to be an environmentally friendly process for urban organic waste, that can represent an opportunity for new uses under the circular economy framework. The binding of cadmium to fulvic-like and humic-like acids extracted from compost of algae and urban residues were evaluated, and the results show significant differences. The fulvic and humic acids from algae compost bind cadmium more...
Characterization of organic matter at different stages of a composting process
Silva, Ana Catarina; Rocha, P.; Antelo, J.; Bento, M. Fátima; Bettencourt, Ana Paula; Ferreira, Paula M. T.; Fiol, S.; Geraldo, Dulce; López, R.The characterization of the organic matter from raw organic wastes, unmatured compost and maturated compost was performed by different techniques: gravimetric, FTIR-ATR, TGA and from the ability of their extracts to bind Cd2+ (evaluating the free cadmium ion by AGNES). Although the amount of humic-like and fulvic-like acids did not change significantly, the structure and properties of the organic matter changed...
The Portuguese Severe Asthma Registry: Development, Features, and Data Sharing ...
Sá-Sousa, A.; Fonseca, J.; Pereira, A.; Ferreira, A.; Arrobas, A.; Mendes, A.; Drummond, M.; Videira, W.; Costa, T.; Farinha, P.; Soares, J.; Rocha, P.The Portuguese Severe Asthma Registry (Registo de Asma Grave Portugal, RAG) was developed by an open collaborative network of asthma specialists. RAG collects data from adults and pediatric severe asthma patients that despite treatment optimization and adequate management of comorbidities require step 4/5 treatment according to GINA recommendations. In this paper, we describe the development and implementation ...
The Diagnosing Challenge of a Positive ANCA Vasculitis in the Paediatric Age
Preto, C.; Silva, A.; Alves, S.; Guedes, M.; Matos, P.; Mota, C.; Rocha, P.; Fernandes, P.ANCA-positive systemic vasculitides, rare in paediatric age, present multiorganic involvement. A female teenager presented with a history of subglottic stenosis diagnosed at the age of 12. From the investigation carried out, we highlight hematoproteinuria and negative ANCAs. At 15 years old, she was admitted for gastrointestinal symptoms and respiratory distress. She presented poor peripheral perfusion, pulmona...
