Stabilisation of soft soils by deep mixing with binders is the most frequently used method of ground improvement in Sweden today, and is increasingly being used internationally. The most common binders employed are cement and lime, but a variety of other binders may also be used for stabilisation of soils. For further development of the deep mixing method, there is a need for more extensive resear

Popular Abstract in Swedish Kursiverade ord förklaras i ordlistan Ateroskleros (åderförkalkning) är en mycket vanlig sjukdom som börjar i tidig ålder med inlagring av bland annat kolesterol i kärlväggarna (aterosklerotiska plack). Om dessa utvecklas vidare leder det till förträngningar av blodkärlen med hjärt- och kärlsjukdomar som konsekvens. Man pratar om två sorters kolesterol; det goda (HDL) The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. Methods that have been utilised are CD spectroscopy, calorimetry both isothermal and temperature scanni

Popular Abstract in Swedish Trycksatt fluidiserande bädd förgasning är ett effektivt sätt för att omvandla biomassa till en gas som kan användas i olika tillämpningar: som bränsle till gasturbiner och förbränningsmotorer, som råvara till kemikalieproduktion eller som bas i tillverkning av syntetiska drivmedel. I motsatts till rötning och jäsning lämnar termisk förgasning inga kontaminerade restproFluidised bed thermal gasification of biomass is an effective route that results in 100 % conversion of the fuel. In contrast to chemical, enzymatic or anaerobic methods of biomass treatment, the thermal conversion leaves no contaminated residue after the process. The product gas evolved within thermal conversion can be used in several applications such as: fuel for gas turbines, combustion engine

Popular Abstract in Swedish Under 1900-talet förändrades musiklivets villkor i grunden. Bruket av nya elektroniska ljudmedier innebar att musik kunde framföras utan musikers faktiska närvaro. En av konsekvenserna var att ”levande musik” myntades som begrepp. Såväl fackföreningar som proggaktivister och kulturpolitiker ville försvara den levande musiken mot dess förmenta motsats, ”mekanisk musik”. As indicated by the subtitle – “legislation, sound media and the defence of live music” – this thesis explores the intersections of politics and technology, economy and aesthetics. It concerns the changing preconditions for the commodification of music during the 20th century, caused by the use of loudspeakers and radio broadcasting, primarily in Sweden. It was around 1930 that “live music” (leva

The top layer of a road is made up of a mixture of stones and bitumen and the durability is dependent on how well the bitumen adheres to the stones. The standard way of determining the bitumen coverage in the industry is the so called rolling bottle method, where a number of stones cov- ered with bitumen are put in a rolling bottle and the bitu- men coverage is estimated after different times. Thi

Abstract in UndeterminedThis thesis consists of five self-contained chapters: Chapter 1:Effects of driving restrictions on air quality and car use in Bogota Rationing car use at certain times of the day based on license plate numbers has become a popular policy to address traffic congestion and air pollution in several cities around the world. This paper analyzes the effects of moderate and drasti

Daß Schweden während der sogenannten Großmachtzeit (1620-1720 ) enge Beziehungen zu den europäischen Kulturländern unterhielt, ist allgemein bekannt. Was aber war nach der Großmachtzeit geschehen, in der Zeit nach den Kriegszügen Karls XII., also während der sogenannten Freiheitszeit zwischen 1720 und 1771? Das Repertoire der Hofkapelle aus diesen Jahren ist größtenteils verschollen. Die beiden Un

Gas chromatographic methods for the determination of cyclic organic acid anhydrides (OAAs) in industrial air are reviewed. The OAAs discussed are phthalic, hexahydrophthalic, methylhexahydrophthalic, tetrahydrophthalic, methyltetrahydrophthalic, trimellitic, maleic, and octenylsuccinic anhydride. Solid sorbent sampling methods, using Amberlite XAD-2 or Tenax, are used for sampling of OAA vapour. T
