  1. 21. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks

    Författare :Karin Karlsson; Bo Stenerlöw; Jörgen Carlsson; Thomas Helleday; Uppsala universitet; []
    Nyckelord :Molecular biology; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionising radiation; high-LET; heat-labile sites; PFGE; Molekylärbiologi;

    Sammanfattning : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. LÄS MER

  3. 22. Radiative Heat Transfer in Suspension-Fired Systems

    Författare :Adrian Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-firing; rotary kiln; combustion; Radiative heat transfer; soot volume fraction;

    Sammanfattning : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. LÄS MER

  4. 23. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

    Författare :Henrik Hofgren; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

    Sammanfattning : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. LÄS MER

  5. 24. An ultra-thin-walled superconducting solenoid for meson-decay physics
