Estudo da dinâmica recente no litoral norte de Portugal com recurso a veículos ...
Henriques, Renato; Chikhradze, Nino; Correia, J.; Gomes, P.; Gomes, Miguel; Gonçalves, C.; Maia, J.; Peixoto, P.; Silva, J.; Pereira, P.RESUMO: Um conhecimento detalhado e atualizado da morfodinâmica local é fundamental para apoiar as decisões e iniciativas de gestão costeira na costa arenosa atlântica do Norte de Portugal. Nos últimos anos foram realizados levantamentos fotográficos de alta precisão com recurso a veículos aéreos não tripulados. As imagens foram processadas e foram produzidos Modelos Digitais de Superfície (MDS) e ortomosaicos ...
Real-world safety data of first-line drugs for rheumatoid arthritis
Ramos Rodrigues, Joana; Pires, L.; Inês, L.; Morgado, M.; Pontes Ferreira, M.; Cunha, A.; Almeida, S.; Santos, Marta; Moniz, A. C.; Melim, D.Objectives: To assess adverse events (AE) associated with first-line therapies for rheumatoid arthritis (RA) in a real-world setting. Material and Methods: Retrospective multicenter cohort study of patients fulfilling classification criteria for RA and followed up in 66 rheumatology centers from the Rheumatic Diseases Portuguese Registry (Reuma.pt). All AE reports associated with first-line disease-modifying an...
Salivary calprotectin: a potential biomarker in inflammatory bowel disease?
Rodrigues, C.; Gomes, A.; Leal, J.; Mendes, K.; Correia, M. J.; Pereira, P.; Martins, R.; Nélio, V.; Rosa, N.; Soares, C.; Ministro, P.
Bairros de Lisboa a três vozes: Conceitos e práticas em antropologia e etnograf...
Cordeiro, G. I.; Cachado, R.; Pereira, P.Quando pensamos em Lisboa como uma cidade de bairros, pensamos, em primeiro lugar, em certos bairros, aqueles que hoje se designam por históricos e/ou populares. Bairros que simbolizam, na sua modéstia, esta pequena metrópole (embora grande, à escala do pequeno país onde se situa) e que se associam, simbioticamente, com alguns traços distintivos da sua urbanidade particular: a sua situação ribeirinha, a sua top...
A unificação dos inventários de geossítios como estratégia para a geoconservaçã...
Aires, R.; Machado, Susana; Pereira, P.; Matos, João Xavier; Brilha, José BernardoSUMMARY: The unification of the two main geosites inventories developed in Portugal (University of Minho and LNEG) is important for the Portuguese geological community, for land use planning and nature conservation procedures. This task aims to reinforce the need of continuing the efforts for a geoconservation strategy in Portugal, stressing the need of the protection of the Portuguese geoheritage and its recog...

Rivals’ exit and vertical merger evaluation
Donna, J. D.; Pereira, P.We discuss a subset of vertical mergers, where the exercise of market power and the efficiencies enabled by a vertical merger reduce rivals' profits, making rivals' exit a potentially serious concern. Rivals' exit can fundamentally alter the welfare analysis of vertical mergers due to the reduction in product variety to consumers and the reduction in the number of competitors that would otherwise exert downward...
Development of WC-NiCrMo hardmetals
Pereira, P.; Rocha, A.M. Ferro; Bastos, A.C.; Oliveira, F.J.; Vilhena, L.M.; Ramalho, A.; Sacramento, J.; Malheiros, L.F.; Senos, A.M.R.The demand for improved components with a wide range of properties is a reality in today's hardmetal market. Furthermore, supply shortages of raw materials such as W and especially Co resulted in rapid price fluctuations. Combined with stricter environmental legislation and health protection, these facts prompt the demand for alternative or modified binders. Therefore, in this work, WC-NiCrMo composites were de...
Effect of different acidic media on the corrosion behaviour of hardmetals with ...
Pereira, P.; Rocha, A. M. Ferro; Sacramento, J.; Oliveira, F. J.; Malheiros, L. F.; Senos, A. M. R.; Bastos, AlexandreHighly corrosive agents, such as saltwater, hydrogen sulphide, hydrofluoric or hydrochloric acids, are frequently found in oil and gas exploration. The high costs associated with the premature replacement of equipment damaged by corrosion and the consequent production losses justify the search for more resistant materials. In this work, the corrosion behaviour of cemented carbides with different Ni-based binder...
Synthetic benchmark for the computation of equivalent properties in coupled flo...
Falcão, F.; Barroso, J.; Murad, M.; Pereira, P.; Vargas, E.; Juvinao, A.; Muller, A.; Roehl, D.; Quevedo, R.; Mejia, C.; Guimarães, L.; Beserra, L.Made available in DSpace on 2022-04-28T19:26:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; In this work, we report on a successful benchmark program motivated by the development of robust hydro-mechanical coupled models capable of providing accurate equivalent properties, such as permeability and porosity, in larger computational cells, typical of an outcrop scale. The cells are occupied by a...
