  1. 1. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008

    Författare :Erik Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IMO; SOx; global cap; Annex VI; MARPOL; air pollution; ships; sulphur oxides; policy-making; emissions;

    Sammanfattning : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

  3. 2. Upscaling and Evaluation of Absorption Based Systems for Co-removal of NOx and SOx from Flue Gases

    Författare :Jakob Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption; gas-phase oxidation; scale-up; Emissions control; SOx; NOx; ClO2;

    Sammanfattning : As long as combustion remains a vital part of the energy system, the removal of nitrogen oxides (NOx) will be a challenge that will need to be addressed. In addition, emissions of sulfur oxides (SOx) will be a problem as long as fuels such as coal and oil are used, as is envisaged in every road map suggested by the Intergovernmental Panel on Climate Change (IPPC).

  4. 3. Sox proteins and neurogenesis

    Författare :Magnus Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The primordium of the central nervous system is specified in a process called neural induction at which point the ectoderm is subdivided into the epidermal ectoderm and the neural plate. With time the neural plate will thicken, fold and form the neural tube. LÄS MER

  5. 4. Structural Studies of Microbial Proteins - From Escherichia coli and Herpesviruses

    Författare :Daniel Gurmu; Heidi Erlandsen; Pär Nordlund; Arne O. Smalås; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CaiB; RibD; YhaK; SOX; ORF60; Herpesvirus; E. coli; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Structure biology concerns the study of the molecular structures of biological macromolecules, such as proteins, and how these relate to the function. Protein structures are also of importance in structure-based drug design. In this thesis, the work has been carried out in two different projects. LÄS MER

  7. 5. SOX in development and disease

    Författare :Idha Kurtsdotter; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : As stem cells are needed not only to build our bodies during development, but also to maintain tissue function during adulthood, it is of great importance to the organism to maintain their integrity. However, stem cells also pose a threat, as oncogenic mutations can transform them or their progeny to malignant cells giving rise to cancer. LÄS MER
