Emissions of greenhouse gases in all sectors of society must reach near zero, in developed countries preferably by 2050, in order to reach climate policy objectives. Alternatives and strategies for the energy and transport sectors are relatively well understood but the basic industries are often overlooked, not least in sustainability transition and innovation system studies. The policy and techn

"Anonyma tentor är just nu en av de hetaste trenderna i högskole-Sverige" skrev Svenska Dagbladet i mars 2008 (http://www.svd.se/nyheter/inrikes/artikel_964731.svd ) Frågan har under några år drivits av studentkårerna, men verkar i de flesta fall ha införts av universitetens och högskolornas ledning utan diskussion och förankring i lärarkåren och utan analys av relationen mellan fördelar och nackd
Language contact through globalisation has indeed influenced various changes in a number of human languages in different corners of the world. In recent years, some scholars have focused particularly on language contact as a reason behind historical changes, and some even consider that the language contact is the major force. In this paper, however, it is argued that language contact can be neglig
Frequency dependence of the permittivity and permeability is inevitable in metamaterial applications such as cloaking and perfect lenses. In this paper, Herglotz functions are used as a tool to construct sum rules from which we derive physical bounds suited for metamaterial applications, where the material parameters are often designed to be negative or near zero in the frequency band of interest.
