Irrigating cork oaks until maturity in the context of climate change: Current i...

Cork oak (Quercus suber L.) is of major importance in the coastal regions of the western Mediterranean basin. However, its widespread chronic decline is compromising the long-term sustainability of its main product, the cork. Fertirrigation has emerged as a potential strategy to accelerate growth and reduce the time to first cork harvest, being discontinued once trees reach their productive stage. This study sy...

Soil conditions influence the advancement of first cork stripping in fertirriga...

Introduction: Fertirrigation in cork oak plantations is a novel approach intended to accelerate growth until trees reach productive maturity, after which they are expected to be managed under rainfed conditions. This study investigated how site quality influenced the timing of the first stripping in a fertirrigated stand. Methods: REGASUBER is a 6-hectare experimental plot located in Coruche, Portugal, installe...

Context-Aware Systems Architecture in Industry 4.0: A Systematic Literature Review

Featured Application This review highlights interoperability, automation, and decision-making as critical requirements for context-aware systems in the manufacturing domain that integrate the principles of Industry 4.0. It discusses relevant patterns and technologies, identifies context gaps, emphasises ontologies' importance, and proposes directions for future research.Abstract Technological evolution has driv...

High-resolution portable bluetooth module for ECG and EMG acquisition

Portable ECG/sEMG acquisition systems for telemedicine often lack application flexibility (e.g., limited configurability, signal validation) and efficient wireless data handling. A modular biosignal acquisition system with up to 8 channels, 24-bit resolution and configurable sampling (1–4 kHz) is proposed, featuring per-channel gain/source adjustments, internal MUX-based reference drive, and visual electrode in...

Efeito de dois sais de lítio no comportamento da Eisenia andrei em ensaios de e...

Diferentes sais de lítio (Li) têm sido usados na avaliação do efeito do lítio (Li) no solo, dificultando a comparação dos resultados e conclusões sobre a contaminação emergente. Este trabalho teve como objetivo estudar o efeito do Li, na forma de dois sais, Li2CO3 (CLi) e Li2SO4 (SLi), através de um teste de evitamento com Eisenia andrei, usando o comportamento de fuga como parâmetro de medição. Foram testadas ...

Automated construction and semantic interoperability for digital twins: integra...

Digital twins are increasingly used, as they allow the creation of detailed virtual representations of physical products and systems. They face, however, significant challenges such as heterogeneous data integration and high costs. This article presents an innovative methodology that uses Large Language Models to unify information and automate the generation of Digital Twin models. The proposal comprises severa...

Integrated valorisation of Agricultural Plastic Waste as a strategy to improve ...

The agricultural sector generates a significant amount of plastic waste, which if not properly managed poses a threat to the environment. This paper introduces an overview on valorisation options of agricultural plastic waste which include recycling, energy recovery, pyrolysis, hydrothermal carbonization and hydrogen production. The publication addresses the importance of the application of an holistic approach...

Climate Effect on Morphological Traits and Polyphenolic Composition of Red Wine...

Wine quality is determined by the development of grape maturation, which is highly dependent on climate variations. Extreme weather events are becoming more common, which will affect the productivity and quality of grapes and wine. Grape development depends on many factors, including weather, and extreme events will influence berry size, skin thickness and the development of some key compounds, such as phenolic...
