  2. 11. Effects of Pulsed Electric Fields on Plant Tissue

    Author : Yongyut Chalermchat; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Electropermeabilization; Pulsed electric fields; Plant Tissue; Teknik;

    Abstract : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. READ MORE

  4. 12. A Simulation Approach to High-Frequency Plasma Waves

    Author : Etienne Koen; Tomas Karlsson; Orsolya Ferencz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Electrostatic waves in the form of Broadband Electrostatic Noise (BEN) have been observed in the Earth's auroral region associated with high geomagnetic activity. This broad frequency spectrum consists of three electrostatic modes, namely electron plasma, electron acoustic and beam-driven modes. READ MORE

  5. 13. Epitaxial Growth and Characterization of SiC for High Power Devices

    Author : Jawad ul Hassan; Peder Bergman; Hidekazu Tsuchida; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Silicon Carbide (SiC) is a semiconductor with a set of superior properties, including wide bandgap, high thermal conductivity, high critical electric field and high electron mobility. This makes it an excellent material for unipolar and bipolar electronic device applications that can operate under high temperature and high power conditions. READ MORE

  7. 15. Studies on neuronal signaling in the hippocampus related to development, pathogenesis and treatment of mood disorders

    Author : Nermin Sourial-Bassillious; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Hippocampus;

    Abstract : The hippocampus is a central organ in the brain which is interconnected with different cortical regions and plays an important role in memory and learning processes. The anatomical position of the hippocampus together with the special sensitivity of its neurons renders it vulnerable to brain injury. READ MORE
