Radial stellar population gradients within dwarf galaxies provide a promising avenue for disentangling the drivers of galaxy evolution, including environment.Within the Local Volume, radial stellar age gradient slopes correlate with interaction history, contrary to model predictions, so dwarfs that are isolated provide a critical control sample.We
The protection against the unintentional islanding of Grid-Tied inverters is an important electrical security issue addressed by the main Standards.This concern is justified in face of the fact that unintentional islanding can lead to abrupt variations of voltage and frequency, electrical damages, professional accidents, power Mustard quality degra
A detailed understanding of what is usual for a species under optimal conditions is critical for identifying and interpreting different features of body function that have known impacts on animal welfare and its assessment.When applying the Five Domains Model to assess animal welfare, the key Commercial Vacuum Cleaner starting point is therefore to
Abstract To gain a deeper understanding of the carbon emission mechanism from transportation facilities, all system elements affecting carbon emissions from regional transportation facilities are identified and analyzed according to panel data from 30 regions in China.A spatial econometric model for carbon emissions from transportation facilities i
