At first I thought it was yet another experiment that generates nonsense papers to show which journals will accept just about anything, but after running a quick search on some of the authors (https://pubpeer.com/search?q=Massimo+Fioranelli https://pubpeer.com/search?q=Massimo+Fioranelli) seems like some sort of academic SEO/backlink/reference/paper mill operation going on? Would be fascinating to map the cross referencing and co-author graph here. Some of the comments on pubpeer are hilarious.
