Conditions are presented for when estimated demand systems automatically satisfy adding up. It is shown that there exist nonlinear demand systems (such as the Almost Ideal Demand System) where adding up is allowed in the model, but where it is not automatically satisfied for the LS and SUR estimates. In these situations it is possible to test the applicability of the model as regards adding up. Th

This thesis deals mainly with biocatalysed methods for stereoselective reduction. D-(S)-chlorolactic acid was produced by both microbial and electromicrobial reduction of chloropyruvate using whole cells of Proteus vulgaris and an artificial electron mediator. The electron donor was formate, hydrogen gas or the cathode in an electrochemical cell. Since chloropyruvate was susceptible to mediator de

Future wireless networks, the systems beyond 3G, will be a combination of different wireless systems. With only one terminal a user should be able to connect to different type of operators, technologies and systems. The issue is also to make the terminal staying online connected, when these changes are made. Both intrasystem handovers and intersystem handovers should be supported by such terminals

Abraham från Godegård – berättelsen om en originell människa och hans musik bygger på Peter Berrys mångåriga efterforskningar om folkskolläraren Abraham Hagholm (1811-1890). Hagholm var son till en fattig torpare i en avlägsen socken av Östergötland och drabbades i tidig ålder av förlamning. Hagholm övervann svårigheterna i sitt liv genom sin starka vilja och sitt livslånga engagemang i musik. IdaAbraham of Godegård – a tale of originality and music Summarizing a story as wild and ambiguous as this one is a difficult task. My story seems to lack order but is a thorough scholarly study at the same time as being a very personal rendition of how I have proceeded along the road of my research and my search for, and relationship to the subject of my story, the school teacher and musician Abrah

Anyone who teas taught a course in Strategic Management probably provides the same basic content to students including the infamous SWOT (strengths, weaknesses, opportunities and threat) analysis along with the identification of functional level, business level, and generic strategies to enhance an organization's competitiveness. What might be different in the teaching of strategic management cour

This paper describes the results of a perception experiment in which subjects listening to a retold story in Dutch were asked to mark various perceived discourse structures and to give their judgements on prominence in the verbatim transcription of that story. They marked discourse boundaries by means of conventional punctuation, indicating perceived non-final, sentence final, and paragraph final
