Drawing on results from a survey made at three local social forums held in Sweden, and interviews with activists taking part in the “co-ordination group” of one of these local forums (and to some extent interviews with Swedish local forum activists that visited the World Social Forum 2007 in Nairobi, Kenya), this paper focus on the transnational and the global dimension of activism within the glob
Major threats to biodiversity and ecosystem persistence are fragmentation of habitats and declining population sizes. For conservation biologists to understand the consequences of declining populations for the long term persistence and recovery of species worldwide, it is important to know and understand the underlying causes of potential threats, such as the depletion of genetic diversity, which

Both within Europe and Sweden energy requirements gradually are becoming more stringent in order to increase the share of new buildings with low energy use. However, if the construction and property owners sectors shall make decisions, about larger investments within the field of low energy buildings, a complete evaluation of the buildings´ performance after a few years of operation is needed. Acc
A 7th order polyphase G/sub -m/C IF filter with automatic frequency tuning, implemented in a 0.35/spl mu/m CMOS process, is presented. The filter has a center frequency of 3MHz and a passband of 1MHz. The image band rejection is higher than 57dB, the stop band attenuation is at least 40dB. The in-band spurious free dynamic range is around 53dB. On-chip automatic frequency tuning provides more than
With increased market competition and advances in modern manufacturing technologies, requirements on customer orders and manufacturing conditions have become more diversified. This paper addresses a dynamic production planning problem for a steel plate fabrication plant with practical flexibility of both customers and manufacturing, such as steel slab-plate matching rules, plate substitution optio
