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 ...
NIR reflective finishing coatings with nanoparticle inclusion
Veloso, Rita C.; Ramos, Nuno M. M.; Ventura, J.; Maia, J.About 40% of the energy consumption of European countries are attributed to buildings. For the construction sector development, it is necessary to ensure the enhancement of sustainability in buildings, eventually by designing new energy- efficient buildings. To accomplish such goal it is crucial to reduce the amount of solar radiation absorbed by buildings. Several solutions have already been reports in the lit...
A multilevel hypernetworks approach to capture meso-level synchronisation proce...
Ribeiro, J.; Lopes, R. J.; Silva, P.; Araújo, D.; Barreira, D.; Davids, K.; Ramos, J.; Maia, J.; Garganta, J.Understanding team behaviours in sports performance requires understanding the interdependencies established between their levels of complexity (micro-meso-macro). Previously, most studies examined interactions emerging at micro- and macro-levels, thus neglecting those emerging at a meso-level (reveals connections between player and team levels, depicted by the emergence of coordination in specific sub-groups o...
Computação móvel em agricultura
Neto, M. C.; Maia, J.; Queiroz e Mello, L.; Fernandes, L. M.A adopção e utilização das novas tecnologias de informação e comunicação nos mais diversos sectores de actividade económica têm vindo a dar origem a novos e interessantes modelos de negócio. Entre as possibilidades com que hoje nos deparamos, e pelo especial interesse de que se reveste para os sectores agrícola, destacamos o denominado m-Business. O m-Business pode ser definido como o uso de tecnologias móv...
Genetic variation in Wnt/β-catenin and ER signalling pathways in female and mal...
Amorim, T.; Durães, C.; Machado, J. C.; Metsios, G. S.; Wyon, M.; Maia, J.; Flouris, A. D.; Marques, F.; Nogueira, Luisa; Adubeiro, Nuno; Koutedakis, Y.The association of genetic polymorphisms with low bone mineral density in elite athletes have not been considered previously. The present study found that bone mass phenotypes in elite and pre-elite dancers are related to genetic variants at the Wnt/β-catenin and ER pathways.
Bone mineral density in vocational and professional ballet dancers
Amorim, T.; Koutedakis, Y.; Nevill, A.; Wyon, M.; Maia, J.; Machado, J. C.; Marques, F.; Metsios, G.S.; Flouris, A.D.; Adubeiro, Nuno; Nogueira, L.According to existing literature, bone health in ballet dancers is controversial. We have verified that, compared to controls, young female and male vocational ballet dancers have lower bone mineral density (BMD) at both impact and non-impact sites, whereas female professional ballet dancers have lower BMD only at non-impact sites.
Descrição, factores, preditores e prognóstico dos derrames parapneumónicos
Ferreira, J.; Maia, J.; Mendonça, C.; Carvalho, D.; Paiva, P.; Correia, J.Resumo Introdução: A infecção pleural é um problema comum na prática clínica. Uma porção significativa das infecções no espaço pleural representa um processo progressivo que leva à transformação de um derrame simples em complicado. A maioria dos autores sugere que a decisão terapêutica depende do estadio de evolução da doença. Objectivos: Descrever e caracterizar os derrames parapneumónicos quanto à forma de ap...
Left-sided infective endocarditis: analysis of in-hospital and medium-term outc...
Ferreira, J.; Gomes, F.; Rodrigues, P.; Araújo Abreu, M.; Maia, J.; Bettencourt, P.; Luz, A.; Torres, S.; Araújo Correia, J.Abstract Introduction: Despite diagnostic and therapeutic advances, infective endocarditis (IE) remains a challenging and potentially lethal disease. The prognosis of IE remains poor; in the last 30 years, its incidence and mortality have only been marginally reduced. Early identification of high-risk patients can change the course of the disease and improve outcomes. Objectives and methods: To describe and inv...
Simulation of the magnetic induction vector of a magnetic core to be used in FF...
Roque, António; Ramos, Sérgio; Barão, José; Machado, M.; Sousa, D. M.; Margato, E.; Maia, J.This paper is a contribution for the assessment and comparison of magnet properties based on magnetic field characteristics particularly concerning the magnetic induction uniformity in the air gaps. For this aim, a solver was developed and implemented to determine the magnetic field of a magnetic core to be used in Fast Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) relaxometry. The electromagnetic field ...
