Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

PLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Analysis of nocturnal urban heat advection using crowd weather stations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The urban heat island is often studied under calm conditions, where its development is strongest. However, effects of wind speed and direction need to be considered for a full understanding. We study the effects of urban heat advection in the urban canopy layer using crowd weather stations. Wind causes increased exposure to urban heat for areas located

Vibrational Analysis of Steelmaking Ladles: Findings from Industrial and Laboratory Studies for Model Development and Stirring Optimization

steel research international, EarlyView.
Vibration signals are generated by argon gas injection in molten metal and are measured in both industrial and laboratory ladles. Distinct frequency bands are identified, corresponding to bubble formation and rupture. The results demonstrate that vibration analysis can provide valuable insights into bubble dynamics and support optimization of gas ...
