Costing the supply chain for delivery of ACT and RDTs in the public sector in Benin and Kenya [PDF]
, 2015 Studies have shown that supply chain costs are a significant proportion of total programme costs. Nevertheless, the costs of delivering specific products are poorly understood and ballpark estimates are often used to inadequately plan for the budgetary ...

Structure of self-assembled Mn atom chains on Si(001) [PDF]
, 2015 Mn has been found to self-assemble into atomic chains running perpendicular to the surface dimer reconstruction on Si(001). They differ from other atomic chains by a striking asymmetric appearance in filled state scanning tunneling microscopy (STM ...
