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

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

När man möter en mamma eller pappa berättar de kanske om sitt barn. Men är barnen deras? I många andra sammanhang talas det om våra barn: skolan, sjukvården, föreningar gör också anspråk på att äga barnen. Världen kring handikappade barn sätter förhållandet på sin spets: där finns en myriad av yrken och institutioner, som hävdar att de både vet mer och vet bäst. Experternas kunskaper är eftersökt

When the Ostra Torn area of Lund, Sweden was further developed in the 1990s, storm water was connected to the old separate storm water system. This increases the risk of flooding near the connection points. In this paper, the function of the system is analyzed using Storm Water Management Model SWMM. Consequences of extreme storms are investigated: It is shown that it is not necessary to connect t
