The thesis presents the results of studies of aerosol particle formation using ion and electron beam analytical techniques. The sources of aerosol particle formation studied are the following: 1. production of primary aerosol particles in the high Arctic region during summers 2. emission of ultrafine aerosol particles from wear on the road-tire interface 3. emission of aerosol particles from di
Abstract in UndeterminedAccurately modelling the dynamic behaviour of multi-storey buildings in wood requires the geometry involved to be represented in great detail, resulting in systems having many millions of degrees of freedom. Consequently, there is a need for model order reduction and the methodology of substructure modelling is employed here to create reduced models for analysis of low-freq
A survey of form and content of fifteenth-century sermons preached to pilgrims at the Birgittine Abbey of Vadstena, Sweden
This thesis contributes to the development of tools and methods for assessing sustainability and applies them to an assessment of the Swedish sugar production system. The thesis’ aims are to compile an overview of the existing approaches for assessing sustainability, to suggest a method(s) for structuring and analyzing complex sustainability issues, and to appraise sustainability impacts from Swed
An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. The graft copolymer is not soluble in oil or water, but it is quite soluble in AOT oil-continuous microemulsi
Popular Abstract in Swedish Under de senaste decennierna har många ekar i Sverige och i övriga Europa uppvisat en klart försämrad hälsa och på många ställen har omfattande ekdöd förekommit. Forskning för att klarlägga orsakerna bakom ekskadorna pågår och ett flertal möjliga förklaringar har lagts fram, men ännu finns ingen lösning på gåtan. De flesta forskare anser dock att skadorna beror på komplThis thesis investigated the occurrence of soilborne species of the plant pathogenic genus Phytophthora in southern Swedish oak forests and their possible involvement in southern Swedish oak decline. The emphasis was on the impact of P. quercina on Quercus robur in acid forest soils. Several different methods, including screening for Phytophthora in oak forest soils, greenhouse experiments with se
Partial migration is a common phenomenon in animals but has mostly been studied in birds. However, partial migration of cyprinid fish from lakes into streams during winter is a wide-spread phenomenon. Despite the potential trophic effects from an absence of dominant planktivores from the lake during large parts of the winter, only few studies have described this phenomenon. This thesis considers v
