The Circular Economy introduced new research challenges to be faced. Linear and circular supply chain comparisons require general methodologies obtain significant scalable results. A two-step methodology is here proposed facilitate the interpretation of results during a Life Cycle Assessment (LCA). Firstly, an LCA analysis has been conducted on four single-use - Polypropylene (PP), Polylactic a...

In  this  research,  biological  removal  of  phenol  and  orthonitrophenol  (2NP)  pollutants  from wastewater  by  continuous  moving  bed  sequencing  batch  reactor  (MSBR)  was  studied.  The experiments were conducted in various operational conditions to find out the optimum level of the significant  parameters.  Best  performance  for  removal  of  Phenols  was  achieved  when  parameter...

We show that the ring of the weight enumerators of a self-dual doubly even code dn in arbitrary genus is finitely generated. Indeed enough elements to generate it are given. The latter result is applied to obtain a minimal set of generators of the ring in genus two.
