The main part of this thesis deals with the effects of adsorbing and non-adsorbing polymers when mixed with microemulsion droplets and bilayers in a lamellar phase. The phase behaviour, microstructure and interactions in a nonionic surfactant/ water/ oil-system, comprising penta ethylene oxide dodecyl ether (C12E5) and decane, was investigated. The microemulsion phase was studied by small angle ne
The principal noise source for a jet engine is associated with the jet exhaust. The acoustical field that is generated by a jet engine before the take-off is considered. The turbulent jet and the mixing of the hot exhaust gas with the cold surrounding air forms an acoustical source. The compressible Navier-Stokes equations describe both flow field as well as sound generation. The acoustic theory u
Popular Abstract in Swedish Polymergeler och deras interaktioner med joniska surfaktanter. Olika typer av hydrofoba polymerer och hydrophobmodifierade polymerer tvärbinds kemisk till geler. Dessa geler tillhör gruppen responsiva geler, vilket betyder att gelerna ändrar sin volym under yttre påverkan. Gelernas volymändring studeras vid tillsats av olika joniska surfaktanter, vid tillsats av saltThe response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. Because of their hydrophobicity the polymers have a strong tendency to associate, both with themselves and with surfactants. Another i
Hybrid systems-those composed of the interaction of discrete and continuous inputs, outputs, states, and dynamic equations-are an important class of models of complex, real-world phenomena. However, the simulation tools currently available seem to be (1) ad hoc retro fitting of existing packages, (2) hastily-built new languages, or (3) specialized software for particular subclasses (e.g., piecewis

The article analyses the origins of the idea of the Swedish government in 1997 to initiate a project, Living History, to inform the Swedish people about the Holocaust.
A number of trends like globalisation, outsourcing, single sourcing, and leanness have together created a more vulnerable supply chain. This increased vulnerability has made supply chain risk issues a hot topic in academia as well as in industry. There has, however, been a lack of suitable models. The objective of this paper is to develop one such model – a conceptual model with the help of which
Rapporten är en sammanfattning av en pilotundersökning av inställningen till ämnesteoretiska studier i samhällskunskap hos färdiga lärare. Utvärderingen har utförts som en enkätundersökning med praktiskt verksamma lärare som utbildats vid Lunds universitet i samhällskunskap enligt 1969 års studieordning.
In this book, nine scholars from six different academic disciplines study various relations between media and monarchy in Sweden from the fifteenth century up until today. With an emphasis on the last one and a half century, the texts primarily analyzes how the Bernadotte family has responded to and used media such as press, film, television and Internet.
