  2. 1. PWO Crystal Measurements and Simulation Studies of Anti-Hyperon Polarisation for PANDA

    Author : Sophie Grape; Tord Johansson; Thomas Nilsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PANDA; PWO; antiproton; hyperon; polarisation; Nuclear physics; Kärnfysik; Kärnfysik; Nuclear Physics;

    Abstract : The Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, will be upgraded to accommodate a new generation of physics experiments. The future accelerator facility will be called FAIR and one of the experimentsat the site will be PANDA, which aims at performing hadron physics investigations by colliding anti-protons with protons.

  4. 2. Applications of Short Extreme Ultraviolet Pulses to the Spectroscopy of Atoms and Molecules

    Author : Allan Johansson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-order harmonics; short pulses; pulse characterisation; sidebands; lifetime measurements; time domain spectroscopy; frequency domain spectroscopy; He; N2; CO; XUV; Atomic and molecular physics; relative polarisation; Atom- och molekylärfysik; Fysicumarkivet A:2003:Johansson;

    Abstract : This thesis is devoted to the characterisation in time and frequency, and to spectroscopic application, of extreme ultraviolet (XUV) pulses. High-order harmonic generation or wave mixing processes were used to produce the pulses in the XUV spectral region. READ MORE

  5. 3. Upconversion Detection for Improved Nonlinear Mid-infrared Spectroscopy in Flames

    Author : Rasmus Lyngbye Pedersen; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared; upconversion; degenerate four wave mixing; hydrogen cyanide; polarisation spectroscopy;

    Abstract : This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). READ MORE

  6. 4. Social differentials in health-related non-employment and poverty : studies on consequences of limiting longstanding illness, musculoskeletal and mental disorders

    Author : Johanna Falk; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The overall aim of the thesis is to increase knowledge on social differentials in employment and income consequences among persons with chronic disease. The studies were conducted in Sweden and different policy context during the first decade of the 2000s. READ MORE

  7. 5. Electrochemical characterisation of porous cathodes in the polymer electrolyte fuel cell

    Author : Frédéric Jaouen; KTH; []
    Keywords : polymer electrolyte fuel cell; cathode; mass transport; porous electrode; modelling; agglomerate model; electrochemical impedance spectroscopy; current interrupt; transient techniques; non-noble catalysts;

    Abstract : Polymer electrolyte fuel cells (PEFC) convert chemicalenergy into electrical energy with higher efficiency thaninternal combustion engines. They are particularly suited fortransportation applications or portable devices owing to theirhigh power density and low operating temperature. READ MORE
