TL;DR: Evaluation of six different forage sources as potential risk factors for colony loss indicated that intensive foraging on any of five of these plant sources was associated with significantly higher winter losses, although this finding requires further study and explanation.

TL;DR: Managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries are presented, and it is found that, overall, larger beekeeping operations with more than 150 colonies experienced significantly lower losses.
Journal ArticleDOI
Calibration of the Numerical Model of a Short-span Masonry Railway Bridge Based on Experimental Modal Parameters
Cristina Amaro da Costa,Diogo Ribeiro,Pedro A. S. Jorge,Rúben Silva,Rui Calçada,António Arêde +5 more
TL;DR: In this paper, the authors presented and discussed the strategies used to identify the most representative modal parameters of a short span masonry railway bridge, estimated by performing vibration testing to validate and update the numerical models for the bridge structural analysis.
