A contested financial frontier: banking and empire building in Eritrea, c.1952–73
2021
AbstractThis article provides an account of the relationship between imperial Ethiopia and Eritrea in the realm of banking governance from the start of the federation to the last years of the imperial regime. It looks in particular at the relationship between the Ethiopian administrations and an Italian bank, Banco di Roma, which had its headquarters in Eritrea from 1948 to 1967 before moving to Addis Ababa. The struggle for control of the economic flows generated by the Italian bank is an index of the changes in centre–periphery linkages between Addis Ababa and the sub-regional centre of Asmara. Archival evidence highlights the multifaced nature of Ethiopian governance and the role perform…
On the effectiveness of different additives and concentrations on the re-building of the molecular structure of degraded polyethylene
2006
Mechanical recycling is an easy and economic way to re-use plastic waste as secondary materials, but, in general, their properties are worse with respect to the reclaimed materials and the virgin polymer. The aim of this work was to study the effect of concentration and reaction kinetics of two additives, an ethylene-co-glycidyl methacrylate (Lotader) and a hydroxylamine derivative (CGX), in the re-building of a degraded polyethylene. CGX is a nitroxyl radical generator able to form branching in polyolefins while the epoxy groups of Lotader can react with the functional groups present in the recycled polyethylene. The results indicate that the CGX has a higher reaction rate than Lotader, pr…
