    Abstract : The influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. READ MORE

  4. 2. Life Cycle Assessment of Building Products. Case Studies and Methodology

    Author : Åsa Jönsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

    Abstract : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.

  6. 4. Usability – Who Cares? : The Introduction of User-Centred Systems Design in Organisations

    Author : Åsa Cajander; Jan Gulliksen; Inger Boivie; Bodil Jönsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; User-Centred System Design; UCSD; Human-Computer Interaction; HCI; Usability; Perspectives; Sensemaking; Communities of Practice; Action research; Interpretations; Organisational change; Work environment; IT systems development; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Abstract : This thesis analyses the difficulties encountered in the promotion of usability, especially in relation to occupation health issues, when developing IT systems in a public authority. It examines what happens when User-Centred Systems Design (UCSD) approaches are introduced to organisations with in-house systems development for their employees. READ MORE

  7. 5. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea

    Author : Anette Jönsson; Lars Rahm; Åsa Danielsson; Tarmo Soomere; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface waves; Wave model; Wave friction velocity; Resuspension; Sediment dynamics; Nitrogen fixation; Baltic Sea; Havsvågor; Östersjön; Oceanografi; Sediment; Oceanography; Oceanografi;

    Abstract : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. READ MORE
