    Sammanfattning : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

    Sammanfattning : The blood/plasma protein biomarker profile represents the pathological and physiological changes relating to human diseases. However, the plasma proteome reflects a high degree of complexity that results in a challenge for most analytical methods in clinical diagnostics. LÄS MER

  4. 3. Pedestal structure and stability in JET-ILW and comparison with JET-C

    Författare :Estera Stefanikova; Lorenzo Frassinetti; Per Brunsell; Joelle Mailloux; KTH; []

    Sammanfattning : Controlled thermonuclear fusion offers a promising concept for safe and sustainable production of electrical energy. However, there are still many issues to be investigated on the way to a commercial fusion reactor. An important point for detailed studies is connected to wall materials surrounding hot thermonuclear plasma. LÄS MER

  5. 4. Controlled Trapping in Laser Wakefield Accelerators

    Författare :Martin Hansson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser; Wakefield; Acceleration; Trapping; Fysicumarkivet A:2016:Hansson;

    Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER

  7. 5. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields

    Författare :Joel Rasch; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corona; inhomogeneous fields; multipactor; Microwave breakdown;

    Sammanfattning : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.
