Quantifying sources of variability in neonicotinoid residue data for assessing risks to pollinators
The U.S. Environmental Protection Agency’s 2014 guidance for assessing pesticide risks to bees relies on higher-tier studies of residues in pollen and nectar to refine pesticide exposure estimates obtained from lower tier information (e.g., default ...

Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)
