  1. 6. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results

    Author : Dan Johansson; Ulf Germgård; Pedro Fardim; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kraft cooking; softwood; hardwood; cellulose; xylan; glucomannan; degradation; dissolution; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. READ MORE

  2. 7. The Dynamics of Firm and Industry Growth : The Swedish Computing and Communications Industry

    Author : Dan Johansson; KTH; []

  3. 8. Customer Benefits in City Logistics : Towards Viable Urban Consolidation Centres

    Author : Henrik Johansson; Dan Andersson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Urban Consolidation Centre (UCC) is a city logistics initiative that has the potential to increase the efficiency of urban freight delivery systems while reducing negative environmental and social effects caused by freight vehicles. One important issue that have hindered longevity of this initiative is its viability, both the financial viability and acceptance from affected stakeholders (also called UCC customers). READ MORE

  4. 9. Exploring Perceptions of Route Environments in Relation to Walking

    Author : Dan Andersson; Peter Schantz; Lina Wahlgren; Eva Andersson; Maria Johansson; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Abstract : Background: Every walk takes place in a route environment, which can play an important role in deterring or facilitating walking. The focus of this thesis is on the perceptions of environmental variables, and how they relate to appraisals of route environments as hindering – stimulating for walking and unsafe – safe for reasons of traffic, in two metropolitan environments.

  5. 10. Mechanisms and DNA Specificity in Site-specific Recombination of Integron Cassettes

    Author : Carolina Johansson; Lars Sundström; Dan Andersson; Didier Mazel; Uppsala universitet; []
    Keywords : Microbiology; lateral gene transfer; site-specific recombination; tyrosine recombinase; integron; single-stranded; DNA hairpin; Mikrobiologi; farmaceutisk mikrobiologi; Pharmaceutical Microbiology;

    Abstract : Bacterial resistance to antibiotics has become a serious problem. This is due to the remarkable ability of bacteria to respond and rapidly adapt to environmental changes. Integrons are elements with the capacity for gene capture by an integron-encoded site-specific recombinase called IntI. READ MORE
