  1. 1. Bacterial cytochromes P450-Studies on Cytochrome P450 102A2 and P450 102A3 of Bacillus subtilis

    Author : Mattias Gustafsson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; AbrB; Spo0A; monooxygenase; heme; Bacillus subtilis; Cytochrome P450; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. READ MORE

    Abstract : The traditional energy system as we know it today will change in the future. There is a worldwide concern about the global warming situation and there are different actions implemented to limit the consequences from, mainly, the use of fossil fuels. READ MORE

  3. 3. Evaluation of energy conserving measures in buildings connected to a district heating system : case studies in Gävle, Sweden

    Author : Mattias Gustafsson; Björn Karlsson; Magnus Åberg; Högskolan i Gävle; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energieffektivisering; miljonprogrammet; solceller;

    Abstract : When different energy conserving measures are implemented for reducing energy use in buildings and the buildings are connected to district heating systems, it is important that an overall system analysis is made which takes into account the effects of total change of energy use due to the energy conserving measures.The method applied in this thesis uses hourly production data for the different production units in the district heating system in Gävle, Sweden.

  4. 4. Type-II interband quantum dot photodetectors

    Author : Oscar Gustafsson; Mattias Hammar; Wenquan Ma; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; photodetector; quantum dot; infrared; MOVPE; thermal imaging; type-II; photoluminescence; III V; InSb; InGaSb; InAs; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).
