    Sammanfattning : Why is it that modern architects and planners ? these benevolent and socially visionary ?experts? ? have created environments that can make one feel so uneasy? Such is the question that eventually grew into this thesis, where the aim is to enter into and understand the gap between ideals and realities in planning and architecture, with particular focus on projects that try to create an ?urban atmosphere?. As a starting point the author returns to the feelings she felt when she first visited one of these expertly planned areas; what the architects had described as an attractive, urban environment was to her a ghost town without life.

    Sammanfattning : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.
