Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]
, 2006 A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...

Social representation of competition and fraud [PDF]
, 2013 Good citizenship includes fair competitive strategies. Dishonest competitive behaviour – such as fraud – can reflect the absence of one main characteristic of good citizenship as mindfulness of laws and social rules.
