  1. 1. There and back again... An Earth magneto-tale : understanding plasma flows in the magnetotail

    Författare :Alexandre De Spiegeleer; Maria Hamrin; Herbert Gunell; Timo Pitkänen; Colin Forsyth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma dynamics; Earth magnetosphere; magnetotail; plasma sheet flows; oscillatory flows; burst bulk flows; tailward flows; rymdfysik; Space Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Sammanfattning : On average, the Earth's magnetotail plasma sheet seems to be a calm region of the magnetosphere where the plasma moves slowly towards Earth. However, the plasma sheet actually hosts many phenomena, some of which can affect Earth. LÄS MER

  3. 2. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Författare :Louis Richard; Yuri V. Khotyaintsev; Daniel B. Graham; Andris Vaivads; Emiliya Yordanova; Vassilis Angelopoulos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma jets; Magnetic reconnection; Particle acceleration; Magnetosphere; Magnetospheric Multiscale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : High-speed plasma flows (jets) are ubiquitous phenomena in the visible Universe. When the fast plasma flow encounters the ambient plasma at rest, it forms a front where its kinetic energy is dissipated. At the jet front, charged particles gain energy from the electromagnetic fields through heating and acceleration. LÄS MER

  4. 3. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Författare :Louis Richard; Yuri V. Khotyaintsev; Tomas Karlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. LÄS MER

  5. 4. From Lab to Chip – and back : Polymer microfluidic systems for sample handling in point-of-care diagnostics

    Författare :Jonas Hansson; Wouter van der Wijngaart; Hywel Morgan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis contributes to the development of Lab-on-a-Chip systems that enables reliable, rapid medical diagnostics at the point-of-care. These contributions are focused on microfluidic Lab-on-a-Chip systems for sepsis diagnosis, autonomous sample-to-answer tests, and dried blood spot sampling. LÄS MER
