Simultaneous OH- and formaldehyde planar-LIF measurements have been performed in an optical engine using two laser sources working on 283 and 355 nm, respectively. The engine used for the measurements was a car diesel engine converted to single-cylinder operation and modified for optical access. The fuel, n-heptane, was injected by a direct injection common-rail system and the engine was also fitt

Recently much attention has been paid to studies concerning bubble dynamics in the cavitation phenomena and this topic has been the subject of many research works. In fact, the simulation of non-spherical bubble dynamics and its interaction with solid boundaries have received much less attention due to the complexity of the problem. One of the main reasons of the structural damages in the cavitati

Popular Abstract in SwedishPopulärmusikens starka ställning idag gör det angeläget för musikvetenskapen att ta dess konstnärliga aspekter på lika stort allvar som ämnet vanligen behandlar konstmusik. Den populära visan lever i en riklig mängd olika former, allt från folkvisor till rockmusik. Ändå är studier sparsamma idag av de sätt ord, ton och röst samverkar på i visan. Denna studie sätter dessaThe aim of this study is to investigate relationships between words, music and voice in contemporary swedish popular ballads – visa – as it is realized in the works of Swedish artist, singer/songwriter Olle Adolphson (b 1934).Entering the world of entertainment in 1956 he quickly became one of the most prominent representatives of the literary branch of popular song in Sweden.

In order to stay competitive and meet the changing needs of the market, construction firms must develop efficient means of gathering and using knowledge of end-users requirements. This study uses two case studies, to explore the knowledge creation of end-users requirements in project driven firms. The focus of the study is the interface between firm and project. The interface is analyzed from both

Popular Abstract in Swedish Tensider, eller amfifiler, är molekyler som består av en hydrofil (”vattenälskande”) och en hydrofob (”vattenskyende”) del. Denna dualistiska karaktär ger tensider speciella egenskaper av vilken den viktigaste är att den självaggregerar i en del lösningsmedel, som i de allra flesta tillämpningar är vatten. Självaggregeringen i vattenlösningar beror på att vattnet vill hThe aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. The phase diagram of the ternary n -nonyl-beta-glucoside (C9G1)/ n -decyl-beta-glucoside (C10G1)/water system has been determined and is discussed in relation to the binary C9G1/water
