  1. 16. A Shift in Urban Mobility and Parking? : Exploring Policies in Relation to Practices

    Författare :Fredrik Johansson; Greger Henriksson; Jonas Åkerman; Pelle Envall; Greg Marsden; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parking; mobility services; flexible parking requirements; sustainable mobility paradigm; Strategier för hållbar utveckling; Strategies for sustainable development;

    Sammanfattning : The transport sector is associated with many environmental challenges, including carbon dioxide (CO2) emissions. Research indicate that CO2 emissions should decrease by at least 50 % per decade in order to be in line with the Paris Agreement, and the transport sector is highlighted as a particularly challenging sector.

  3. 17. Bronchial hyperresponsiveness of ß-adrenoceptor agonists and antagonists in guinea pig airways

    Författare :Fredrik Johansson; Sven-Erik Dahlén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Asthma is one of the most common diseases in the industrialised countries. The underlying mechanisms are complex and still not fully understood although inflammation of the airways plays an important role. LÄS MER

  4. 18. Food and Packaging Interactions Affecting Food Quality

    Författare :Fredrik Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sorbed vegetable oil; oxygen transmission rate; food packaging; supercritical fluid extraction; inertness test; refillable PET bottles; permeability; aroma; interactions; sorption;

    Sammanfattning : Food and packaging interactions that may impair the food quality have been studied and methods to determine these interactions have been developed. An off-line supercritical fluid extraction method using carbon dioxide was developed and used to extract sorbed low molecular weight compounds from polymer films. LÄS MER

  5. 19. Global geometric graph kernels and applications

    Författare :Fredrik Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis explores the topics of graph kernels and classification of graphs. Graph kernels have received considerable attention in the last decade, in part because of their value in many practical applications, such as chemo informatics and molecular biology, in which classification using graph kernels have become the standard model for several problems.

  7. 20. Interplay between DNA repair pathways at replication forks in mammalian cells

    Författare :Fredrik Johansson; Dag Jenssen; Klaus Erixon; Harry Vrieling; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi;

    Sammanfattning : Cellular DNA is continuously being damaged by various agents of both endogenous and exogenous origin including a wide range of chemical compounds, UV-light and ionizing radiation. In order to remove lesions from the DNA and maintain genomic stability, different repair processes have evolved. LÄS MER
