Rättens Dilemma: Om konflikthantering i ett mångkulturellt samhälle

Dagens Sverige är ett mångkulturellt samhälle, och bristen på stabilitet i relationerna mellan svenskar och olika invandrargrupper banar vägen för konfrontationer, som i sin tur materialiserar sig som "elände, våldsdåd och bråk". Det mångkulturella Sverige blir på så sätt en grogrund för etnokulturella motsättningar. Eftersom rätten i regel betraktas som samhällets konfliktlösande maskineri par ex

Modelling moisture conditions in cementitious materials – some present challenges

The moisture conditions of a concrete have a decisive effect on several properties and many parts of deterioration processes. The moisture distribution in a concrete structure is determined by the concrete composition, curing and the microclimate in the different parts of the structure. A prediction requires access to data on the time-dependency of the binder reactions, moisture fixation and moist

Polymer effects on microemulsions and lamellar phases

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

Modeling of the acoustical field due to a jet engine with ground effect

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

Polymer Gels and their Interactions with Ionic Surfactants

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

Simulation of Hybrid Systems

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
