  1. 1. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Author : Christina Isaxon; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Abstract : Popular Abstract in Swedish Ta ett djupt andetag och tänk på vad du nu har i lungorna! Jo, det är luft, förstås, syre kväve och sådant. Men det är också något annat. I varje kubikcentimeter du andas in finns tusentals partiklar, alla för små för att kunna ses med blotta ögat. Om dessa partiklar handlar denna avhandling. READ MORE

  2. 2. Ultrafast opto-optical control of extreme ultraviolet light pulses

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Samuel Bengtsson; Lunds universitet.; Lund University.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet; controlled emission; Free induction; time-dependent spectroscopy; noble; High order harmonic generation; phase-control;

    Abstract : Extreme ultraviolet (XUV) light is a valuable frequency range for ultrafast optics experiments. The short wavelength is a requirement for ultrashort pulses, which are widely used to characterize fast dynamics. Additionally, the high photon energy enables quantum control of high frequency transitions in atoms. READ MORE

  3. 3. HCCI Combustion - Engine Operation and Emission Characteristics

    University dissertation from Department of Heat and Power Engineering, Lund university

    Author : Magnus Christensen; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

    Abstract : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. READ MORE

  4. 4. Controlled growth of hexagonal GaN pyramids and InGaN QDs

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Anders Lundskog; Linköpings universitet.; Linköpings universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gallium-nitride (GaN) and its related alloys are direct band gap semiconductors, with a wide variety of applications. The white light emitting diode (LED) is of particular importance as it is expected to replace energy inefficient light bulb and hazardous incandescent lamps used today. READ MORE

    Abstract : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Transplanting bone graft from one site in the patient to the site of fracture or bone void, i.e. READ MORE
