The impact of the summer 2007 forest fires in Greece: Recent environmental mobilizations, cyber-activism and electoral performance

This report circumambulates around the environmental issue, examining mobilizations in favour of public access to the seafront and protest events against the recent devastating forest fires. By framing this discussion within existing scholarly contributions on related dimensions of the environmental issue (environmental consciousness, grassroots environmental contestation) in Southern Europe in general and Greece in particular, it suggests that the environmental mobilization dynamic in Greece has been infused with a new, global, mobilizing resource that offers new avenues to evaluate the potency of Greek civil society. Finally, the article discusses the results of the 2007 national elections and ponders the chances of political ecology becoming a permanent feature of Greek parliamentary politics.

Active Phase Conjugating Lens With Sub-Wavelength Resolution Capability

Experimental results are presented for the focusing capability of an active phase conjugating lens for a single and a dipole source pair and these are compared with predictions. In addition for a single source we illustrate the ability of the lens to project a null at the lens focus instead of a peak. A scheme is also presented such that when a source or pair of sources is imaged through an identical pair of passive scatterers located symmetrically about the lens that imaging with sub-wavelength resolution is possible. The rationale for the operation of the lens and aberrations observed due to its finite array size is discussed and is supported throughout by means of numerical simulation.
