  4. 2. Randomised clinical trials with hyperbaric oxygen in COVID-19 and Long COVID : transcriptomic insights into benefits and harms

    Author : Anders Kjellberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The flow from transcription of genes through translation and processing of proteins is a common basis for all life. Redox homeostasis is crucial for the defence against oxidative stress. We adapt through hormesis; non-lethal stress regulates redox-sensitive systems to maintain homeostasis. READ MORE

  5. 3. Manufacturing system data management and development : towards a STEP compliant reference model for manufacturing

    Author : Mattias Larsson; Torsten Kjellberg; Anders Dannstedt; KTH; []
    Keywords : Information Management; Industrial Engineering; Collaborative Engineering;

    Abstract : Collaborative engineering assumes a common understanding of the domain. To make joint decisions the engineers must have a common language to start from.
