Hot and toxic: accumulation dynamics and ecotoxicological responses of mussel M...

Climate change is increasing marine heatwaves (MHWs) frequency and severity worldwide. These extreme events often cause bivalves' mass mortality and facilitate the growth, proliferation and dispersion of toxinproducing microalgae blooms associated with threats to seafood safety. Yet, the interactive effects between MHW and uptake of marine biotoxins by biota are a novel topic still lacking thorough research, fr...

Applying deep learning to real-time UAV-based forest monitoring: Leveraging mul...

Rising global fire incidents necessitate effective solutions, with forest surveillance emerging as a crucial strategy. This paper proposes a complete solution using technology that integrates visible and infrared spectrum images through Unmanned Aerial Vehicles (UAVs) for enhanced detection of people and vehicles in forest environments. Unlike existing computer vision models relying on single-sensor imagery, th...

Caso clínico: síndrome de Eisenmenger

Introdução: A síndrome de eisenmenger consiste numa doença cardiovascular, tipicamente associada a um defeito cardíaco, que condiciona aumento da resistência vascular pulmonar e hipertensão pulmonar. Os defeitos mais típicos consistem em comunicações interauriculares, comunicações interventriculares, foramen oval patente, ductos arteriosos patentes, entre outros. Com o aumento da resistência vascular pulmonar e...

Surface Roughness Evaluation of Resin Composites after Finishing and Polishing ...

The purpose of this study was to evaluate the effect of two finishing and polishing methods on the surface roughness of different resin composites. Twenty-two disk-shaped specimens of five resin composites Zirconfill® (ZF), Filtek™ Supreme XTE (FS), Brilliant EverGlow™ (BG), Ceram.X® Duo (CD), and Harmonize™ (HA) were prepared for each one using a silicon mold. Both surfaces of each specimen were first grinded ...

Speculative computation: application scenarios

First Online: 24 April 2022; Artificial intelligence and machine learning have been widely applied in several areas with the twofold goal of improving people’s well-being and accelerating computational processes. This may be seen in medical assistance (e.g., automatic verification of MRI images) and in personal assistants that adapt the content to the user based on his/her preferences, to optimize query respons...

Influence of indoor air quality on sleep quality of university students in Lisbon

Sleep is a crucial aspect of human daily life since it allows us to recover from physical and psychological fatigue and its lack can bring several consequences to human health. People spend around one-third of their life sleeping but, despite that, their exposure to pollutants during sleep is often neglected. Specifically, students typically change their habits after entering university, due to the freedom that...

Livro de Atas - 4.ª Conferência Campus Sustentável (CCS2022)

A sustentabilidade, nas suas variadas vertentes designadamente ambiental, económica e social, tem estado, desde sempre, no topo das prioridades do Instituto Politécnico de Leiria (IPL). Esta postura encontra-se espelhada, nomeadamente, no plano estratégico 2030 da instituição que prevê um conjunto alargado de medidas que fomentam a adoção de práticas sustentáveis nas atividades e quotidiano da comunidade académ...
