Several transport mechanisms contribute to macrosegregation formation in Direct Chill (DC) casting of aluminium. The latter include solidification shrinkage induced flow, thermal-solutal convection and grain motion. The relative importance of these transport mechanisms depends on process parameters...

Macrosegregation refers to the inhomogeneous distribution of solute elements at the scale of cast product. It is a severe defect affecting the quality of cast product produced through Direct Chill (DC) casting process. Several casting parameters and transport mechanisms such as shrinkage induced...

Supply risk analysis of silver for solar thermal power plants. An analysis of global value chains. Ana Rosa Gamarra, Santacruz Banacloche and Yolanda Lechón - 3 Implementing sustainability in laboratory activities: A case study on magnetron sputtering deposition synthesis based on Life Cycle...

Macrosegregation is a severe defect present in direct-chill (DC) cast aluminium ingots and billets. In the recent years, experimental studies were conducted to modify and to an extent optimize macrosegregation formation by modifying the inlet melt flow. Due to several limitations, the grain settling...

Objectives: The general practitioners' (GP) role in the care of mental health patients has received increased attention. The literature underlines the need for integration of primary and specialist services, but cross-boundary continuity for patients with severe conditions may be particularly poor...

Marine litter in the Arctic Basin is influenced by transport from Atlantic and Pacific waters. This highlights the need for harmonization of guidelines across regions. Monitoring can be used to assess temporal and spatial trends but can also be used to assess if environmental objectives are reached...

This work introduces a decentralized management concept for the urban charging hubs (UCHs) where electric vehicles (EVs) can access multiple charger clusters, each controlled by an aggregator. The given day ahead schedules (DASs) and peak power limits (PPLs) of the aggregators providing grid-to...
