Abstract:
... In Bulgaria, only Dobrava orthohantavirus has been detected in patients and in rodents. In order to elucidate possible Puumala orthohantavirus (PUUV) circulation, 131 bank voles (Myodes glareolus) were captured. PUUV RNA was detected in 14 (10.7%). Partial L segment sequences were recovered from six M. glareolus. Phylogenetic analysis showed that all PUUV sequences from this study clustered togeth ...

Abstract:
... While the critique to economic growth is quintessential in the degrowth scholarship, one may observe a similar focus in various environmental justice movements around the world. This is particularly visible when it comes to the increasing perception that mega-development projects are both unjust and unsustainable, threatening the survival of people and environments. In this paper, we illustrate th ...
