In the context of the ever-increasing political problematization of migration in Europe, agencies charged with migrant administration create diverse categories of difference to distinguish between the 'deserving migrant' and the illegal one: They assess the detainability or the credibility of asylum seekers, the danger posed by Islamic organizations, and make situational decisions that determine whether migration or labour law applies to individual agricultural workers. In this book, each chapter analyses how organizational interpretations 'in service of' the common good shape bureaucratic (...) practices. Together, these ethnographic analyses reveal how migration policies in different European countries take shape in administrative practice."--Back cover. (shrink)

The effect of mechanical deformation on the formation of quasicrystals in Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 glassy ribbons has been investigated. The mechanical treatment drastically affects the crystallization behavior and, in particular, suppresses primary quasicrystal formation. However, quasicrystals can be formed by the addition of the appropriate amount of zirconium. This indicates that if a particular short-range order (e.g., icosahedral) is required for quasicrystal formation and if this short-range order is altered during milling, it can be restored by appropriately adjusting the chemical composition.
