The category ''magic'' , long used to signify an allegedly substantive |

type of activity distinguishable from ''religion'', has nearly been dismantled by recent historical and social-scientific approaches to religious studies. While recognising and at times reinforcing this stance, the essays in this collection show that there is still much to be learned about the cultural context of early Judaism and Christianity by analysing ancient texts which either use ''magic'' as a category for purposes of deviance labelling or promote behaviour of a broadly magico-religious variety.

Sommario/riassunto |
|
Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park's transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in |
