Cork oak woodlands and decline: a social-ecological review and future transdisc...

Lopes-Fernandes, Margarida; Martínez-Fernández, Ernesto; Alves, Rui; Boa-Nova, Daniel; Branquinho, Cristina; Bugalho, Miguel N; Campos-Mardones, Felipe

Cork oak woodlands are socio-ecosystems recognized as biodiversity hotspots, a fundamental economic source for companies and local communities as well as an identitarian landscape for residents and visitors. Cork oak woodlands, however, are facing tree mortality and lack of regeneration. Considering the oak decline scenario, we present Iberian cork oak montado/dehesa as a socio-ecosystem facing climate change, ...


Mechanical and surface properties of a 3D-printed dental resin reinforced with ...

Salgado, Helena; Fialho, Joana; Marques, Marco; Vaz, Mário; Figueiral, Maria Helena; Mesquita, Pedro

Objectives: Commercial photocurable polymers used in dental additive manufacturing still have mechanical limitations. The incorporation of graphene may provide interesting advantages in this field. This study aimed to evaluate in vitro the effect of adding graphene nanoparticles to a 3D-printed polymethylmethacrylate dental resin in terms of surface roughness, flexural properties, and hardness. Methods: A 3D-pr...


Human Plasma Metabolomics in Age-Related Macular Degeneration: Meta-Analysis of...

Laíns, Inês; Chung, Wonil; Kelly, Rachel S.; Gil, João; Marques, Marco; Barreto, Patrícia; Murta, Joaquim N.; Kim, Ivana K.; Vavvas, Demetrios G.

The pathogenesis of age-related macular degeneration (AMD), a leading cause of blindness worldwide, remains only partially understood. This has led to the current lack of accessible and reliable biofluid biomarkers for diagnosis and prognosis, and absence of treatments for dry AMD. This study aimed to assess the plasma metabolomic profiles of AMD and its severity stages with the ultimate goal of contributing to...

#056. Análise da distribuição de tensões em implantes angulados de diferentes c...

Xavier, Joana; Borges, Tiago; Marques, Marco; Parente, Marco; Faria‐Almeida, Ricardo; Tavares, João Manuel R. S.

Objetivos: O principal objetivo deste estudo in vitro foi avaliar, com base no método dos elementos finitos, o uso de implantes curtos em reabilitação mandibular total e como o comprimento desses implantes influencia a distribuição de tensões durante a aplicação de cargas mastigatórias em reabilitações mandibulares, de acordo com o conceito All‐on‐4®. Materiais e métodos: Foi realizada a modelização de um impla...


Total ossicular replacement prosthesis of the middle ear: a biomechanical analysis

Gentil, Fernanda; Marques, Marco; Parente, Marco; Martins, Pedro; Santo, Carla; Jorge, Renato Natal

The main goal of the present study is to analyze and characterize the behavior of the middle ear, when a total ossicular replacement prosthesis (TORP) is used in the ossicular chain, in order to troubleshoot conductive hearing loss. Using a finite element model (FEM), a dynamic study of the middle ear was made. The displacement values were obtained at the umbo and stapes footplate, for a sound pressure level of...


Análise dinâmica do comportamento mecânico do ouvido médio com prótese total

Gentil, Fernanda; Marques, Marco; Garbe, Carolina; Santos, Carla; Parente, Marco; Martins, Pedro; Jorge, Renato

O presente trabalho tem como objetivo analisar e caracterizar o comportamento do ouvido médio quando uma prótese total substitui os elementos da cadeia ossicular de forma a solucionar problemas de surdez de transmissão. com base num modelo geométrico da cadeia ossicular saudável, a partir de imagens de TAC, foi criado um modelo onde uma prótese total foi incluída, assim como todos os objetos inerentes a esta ad...

Design and Implementation of IEEE 802.16 Radio Links with Relays

Marques, Marco; Ambrósio, João; Reis, Carlos; Gouveia, David; Robalo, Daniel; Velez, Fernando José; Costa, Rui; Riscado, José

This paper addresses aspects of design and planning of a Wireless network WiMAX (IEEE 802.16) to establish a point-to-point, PTP, link from the Health Sciences Faculty of University of Beira Interior (FCS/UBI) to Hospital Sousa Martins (Guarda), and also presents a field trial where we tested point-to-point links with pre-WiMAX equipment. The design of the link had into consideration the carrier to noise ratio,...
