Effect of Depth across a Latitudinal Gradient in the Structure of Rhodolith Sea...

Rhodolith seabeds are ‘ecosystem engineers’ composed of free-living calcareous red macroalgae, which create extensive marine habitats. This study addressed how depth influenced the structure (size and morphology) of rhodoliths and the abundance of associated floral and faunal epibionts across the Eastern Atlantic Ocean. Sampling was carried out at two sites within five regions (Brittany, Galicia, Madeira, Gran ...

Remote Monitoring of Energy-autonomous Constructed Wetlands

Constructed Wetlands systems (CW) are nature-based and sustainable technology for treating wastewater, contributing to the management and protection of freshwater resources. Moreover, CW can contribute to valorizing waste materials, producing reclaimed water for diverse applications, and producing plant biomass that can be material and energetically valorized. Because CW efficiency depends on several mechanisms...

Democracia e plutocracia nas companhias coloniais pombalinas, 1757-1777

A literatura em história empresarial tem demonstrado que a liquidez dos títulos de propriedade das companhias teve consequências nas estruturas de distribuição do capital e do poder de decisão. Este artigo estuda as transações de ações das companhias coloniais pombalinas em comparação com a United East India Company. Encontrou uma distribuição do capital por acionista mais democrática do que em Inglaterra, mas ...

Levelling-up rhodolith-bed science to address global-scale conservation challenges

Global marine conservation remains fractured by an imbalance in research efforts and policy actions, limiting progression towards sustainability. Rhodolith beds represent a prime example, as they have ecological importance on a global scale, provide a wealth of ecosystem functions and services, including biodiversity provision and potential climate change mit-igation, but remain disproportionately understudied,...

Carbon footprint of tourism sector in Portugal: Calculator self-validation

In this work, a Carbon Footprint (CF) calculator developed to the tourism sector in Portugal, was validated. The CF calculator self-validation was based on the comparison of the results obtained with two tools available online (Carbon Footprint Ltd-CFL and Climate Care-CC) and with a Life Cycle Assessment (LCA) performed using the SimaPro PhD software. The calculator is based in the CO2e emissions of 6 componen...

Halochromic inks applied on cardboard for food spoilage monitorization

Control of food spoilage is a critical concern in the current world scenario, not only to ensure the quality and safety of food but also to avoid the generation of food waste. This paper evaluates a dual-sensor strategy using six different pH indicators stamped on cardboard for the detection of spoilage in three different foods: beef, salmon, and strawberries. After function validation and formulation optimizat...

A Rare Case of Unilateral Tongue Edema with Angiotensin Converting Enzyme Inhib...

Angiotensin converting enzyme inhibitors (ACEi) are widely used for the treatment of multiple conditions such as hypertension, heart failure and chronic kidney disease. Angioedema is a rare but potentially fatal complication of ACEi use and unilateral tongue edema is a very rare presentation. We report a case of a 55-year-old man, with a history of hypertension, on enalapril for three years, who presented to th...

Population density, reproduction cycle and nutritional value of Sphaerechinus g...

Sea urchins play an important role in island coastal ecosystems as keystone species and as potential resources for harvesting and aquaculture. In Southern Europe, the most valuable and harvested species is the European purple sea urchin Paracentrotus lividus, but there is a growing interest to explore other edible species like the blunt sea urchin Sphaerechinus granularis. The echinoderms biodiversity of Madeir...
