Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems.New technologies are emerging such as re

It has been proposed that the EU Ecodesign Directive can promote resource efficiency through relevant ecodesign requirements. This paper examines the potential for rare earth element (REE) resource efficiency improvements in the event the current regulation for electric motors under the Ecodesign Directive is to be extended to comprise REE-based permanent magnet motors. The research is based on li

Det grundläggande problem som denna bok behandlar är en till synes växande klyfta mellan världsvida relationer och människors behov av geografisk närhet och ögonkontakt. Författaren behandlar frågor som rör tekniken och den sociala kommunikationens villkor, eller uttryckt på annat sätt, människans förmåga och möjligheter att bemästra det geografiska rummet. Europas geopolitiska karta känneteckna

This thesis addresses; (1) the microdialysis experiment, application and methodology to maximise its performance when sampling from enzymatic bioprocesses, (2) electrochemical detection and electrochemical oxidation of carbohydrates on Au as well as Cu electrodes in alkaline solutions, and (3) coupling and maximising the performance of a microdialysis sampling based high performance anion exchange

Popular Abstract in Swedish I flera tusentals år har människan använt sig av naturen till hjälp för att bota åkommor och krämpor. Det som hon har dragit nytta av då är att alla växter och plantor producerar flertalet små föreningar till skydd eller nytta för plantan. Dessa som föreningar kan då interagera med andra växter och organismer till exempel som ett skydd mot att bli uppäten, som en lockelNatural products have until recently provided the only remedy for treatment of diseases. The development of modern chemistry in the last centuries has opened the door for tapping into the chemical diversity found in nature. Synthetic natural products, together with analogues, are an important piece in the puzzle towards curing many ailments. In this thesis, synthetic endeavors towards different bi

Popular Abstract in Swedish Slemhinnorna i näsan, bihålorna, nasofarynx (nässvalgrummet), örontrumpeten och främre delen av mellanörat, är beklädda med celler på vars yta det finns flimmerhår (cilier). De ciliebeklädda slemhinnorna är täckta av ett tunt slemskikt som transporteras av ciliernas rörelser. I slemskiktet fastnar inandade partiklar, bakterier och döda celler, och transporteras av cilieThe aim with this thesis was to investigate effects of vasoactive mediators on mucociliary activity and blood flow in rabbit and human experimental models. Mucociliary activity in vivo and ciliary beat frequency (CBF) in vitro were measured with photoelectric techniques. Blood flow was measured with laser Doppler flowmetry. Substance P (SP) and methacholine increased human nasal blood flow. Pretre

This paper shares the experiences of 5 universities involved in a benchmarking exercise on e-learning in 2009 through ESMU. A total of 9 European universities participated in the exercise with the purpose of evaluating their existing e-learning practices and policies and getting advice on which areas to improve and how. Initially, the paper discusses the benchmarking concept and reasons why insti

This paper introduces the notion of surprising institutions. We often carry incorrect beliefs about the world surrounding us and we are often mistaken about the nature of the institutional structure. The case story in this paper shows that an institution may come as a surprise, even though its origins lies some 500 years back, and that the information we receive as feedback on our actions does not
