  1. 6. Turbocharged HCCI Engine, Improving Efficiency and Operating Range

    Författare :Thomas Johansson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; NVO; turbo; direct injection; combustion; CAI; low temperature; simulation; engine;

    Sammanfattning : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. LÄS MER

  3. 7. Multi-element trace analysis by proton induced X-ray emission

    Författare :Thomas B Johansson; Internationella miljöinstitutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:000;

  4. 8. Profilin:actin in cell motility : A search for profilin:actin binding proteins

    Författare :Thomas Johansson; Roger Karlsson; Björn Öbrink; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; profilin; actin; Cell biology; Cellbiologi;

    Sammanfattning : The profilin:actin complex is a major source of actin for actin filament growth in vivo. A number of proteins regulating either profilin or actin has been described since profilin:actin was isolated during the 1970s. Since then, profilin and actin and their binding partners have been intensively studied. LÄS MER

  5. 9. Multidrug-Resistant Escherichia coli and Klebsiella pneumoniae : Treatment, Selection and International Spread

    Författare :Thomas Tängdén; Otto Cars; Anders Johansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Escherichia coli; Klebsiella pneumoniae; extended-spectrum beta-lactamases; carbapenemases; metallo-beta-lactamases; synergy; antibiotic interventions;

    Sammanfattning : The prevalence of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum beta-lactamases (ESBLs) and carbapenemases is increasing worldwide. Therapeutic options for infections with these bacteria are limited not only by the production of ESBLs and carbapenemases, which confer resistance to cephalosporins and carbapenems, but also by frequent co-resistance to other antibiotics.

  7. 10. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Mats K G Johansson; Lars Kloo; KTH; []
    Nyckelord :Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

    Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER
