Estudo da dinâmica recente no litoral norte de Portugal com recurso a veículos ...

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 ...

Portuguese recommendations for the management of Raynaud’s phenomenon and digit...

Objective: To develop evidence-based recommendations for the non-pharmacological and pharmacological management of Raynaud's phenomenon (RP) and digital ulcers (DUs) in patients with systemic sclerosis and other immune-mediated connective tissue diseases (CTDs). Methods: A task force comprising 21 rheumatologists, 2 surgeons (vascular and plastic), 2 nurses, and 1 patient representative was established. Followi...

Racing performance of the Quarter Horse: genetic parameters, trends and correla...

The aim of this study was to evaluate the sprint racing performance of Quarter Horses in Brazil. Estimating genetic parameters, trends and correlations were obtained by single- and two-trait analyses using Bayesian inference (earnings to 2 years of equestrian age, best time and time class at distances of 301 m and 402 m). The data comprised a period of 38 equestrian years (1978 to 2015) with 23,482 sprint race ...

Optimization of key growth parameters involved in biomass production of Pavlova...

Microalgae have been presented as an interesting source of bioactive compounds for human consumption in several industries, such as nutraceutical, pharmaceutical or cosmeceutical. Their rich composition in anti-inflammatory and antioxidant compounds (e.g., polyunsaturated fatty acids (PUFAs), proteins) have shown protective effects against several human diseases (e.g., cardiovascular, cancer). Despite their inc...

Can sheep livestock systems based on dynamic grazing influence soil compaction?...

Deferred grazing (DG) consists in adapting the number of animals and the number of days grazed to the availability of pasture. Compared to continuous grazing (CG), which is based on a permanent and low stocking rate, DG is a management strategy that aims at optimizing the use of the resources available in the Mediterranean Montado ecosystem. This study with sheep grazing, carried out between 2019 and 2021 on a ...

Reconfiguring the battery innovation landscape

Batteries are critical for energy transition strategies. This paper offers a comprehensive assessment of the trends and developments of battery innovation. Over 700,000 patents from the period of 2005-2019 are compiled and analyzed. Leading patent applicants and countries of origin are identified. Major patent applicants are mostly large East Asian companies, while Japan and South Korea are the leading countrie...

Maximizing non-aeronautical revenues in airport terminals using gate assignment...

Airports must ensure that their operations can efficiently adapt to the emerging needs considering both the passenger experience and their economic viability. One way to achieve this is by optimizing the airport operations, aiming to maximize revenue levels considering operational objectives and passenger requirements inside the airport. This study presents an original mixed-integer linear programming model (MI...

Joint beamforming algorithm for multi-stream MIMO systems assisted by multiple ...

In recent years there has been a growing interest in reconfigurable intelligent surfaces (RISs) as enablers for the realization of smart radio propagation environments which can provide performance improvements with low energy consumption in future wireless networks. However, to reap the potential gains of RIS it is crucial to jointly design both the transmit precoder and the phases of the RIS elements. Within ...

Technological features of smartphone apps for physical activity promotion in pa...

Introduction: Low physical activity (PA) levels have a negative impact on the health status of patients with Chronic Obstructive Pulmonary Disease (COPD). Smartphone applications (apps) focused on PA promotion may mitigate this problem; however, their effectiveness depends on patient adherence, which can be influenced by the technological features of the apps. This systematic review identified the technological...
