Learning Objects and their implications on Learning: a case of developing the foundation for a new Knowledge Infrastructure

In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it

Studies of aerosol particle formation from various sources using ion and electron beam analytical techniques.

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

Coupling elements for substructure modelling of lightweight multi-storey buildings

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

Sustainability of the Swedish Sugar Sector : Assessment Tool Development and Case Study Appraisal

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

Effects of a Novel Amphiphilic Graft Copolymer on Ternary Mixtures of Surfactant, Water, and Oil

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
