    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high voltage techniques; numerical modeling; electrical discharge in gases; streamer mechanism; leader channel; Engineering Science with specialization in Atmospheric Discharges; Teknisk fysik med inriktning mot atmosfäriska urladdningar;

    Abstract : This dissertation deals with research on the numerical modelling of electrical discharges in laboratory long air gaps excited with positive switching impulses. It begins with the preliminary work of several scientists during the last decades, making a detailed analysis of different approaches for modelling all the stages in a full discharge. READ MORE

  4. 2. Impact of genetic and environmental factors in intestinal inflammation

    Author : Oscar Eduardo Diaz Perez; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The gastrointestinal tract, is continuously exposed to a wide variety of stimuli, including dietary-derived metabolites, environmental compounds and the microbiota. Since these antigens can be beneficial or detrimental for the organism, proper sensing of the luminal content is essential for orchestrating both pro-inflammatory and tolerogenic immune responses on demand and therefore, ensure the establishment of intestinal homeostasis.
