    Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

  2. 2. Infectious immunity and pneumococcal vaccine responses in multiple myeloma and related disorders

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Karlsson; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multiple myeloma; Waldenstrom s macroglobulinemia; MGUS; elderly; immunity; infection; pneumococcal vaccination; ELISA; opsonophagocytosis;

    Abstract : Multiple myeloma (MM), Waldenstrom’s macroglobulinemia (WM), and monoclonal gammopathy of undetermined significance (MGUS) are B cell conditions associated with suppressed immune functions and susceptibility to infection. Severe pneumococcal disease is common not least in MM patients and vaccination is considered important, although the protective efficacy is debated. READ MORE

  3. 3. Optical parametric amplification with periodically poled KTiOPO4

    University dissertation from Stockholm : KTH

    Author : Anna Fragemann; Fredrik Laurell; Ebrahim-Zadeh Majid; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric amplification; optical parametric generation; optical parametric oscillation; TECHNOLOGY Engineering physics Optical physics; TEKNIKVETENSKAP Teknisk fysik Optisk fysik;

    Abstract : This thesis explores the use of engineered nonlinear crystals from the KTiOPO4 (KTP) family as the gain material in optical parametric amplifiers (OPAs), with the aim to achieve more knowledge about the benefits and limitations of these devices. The work aims further at extending the possible applications of OPAs by constructing and investigating several efficient and well performing amplifiers. READ MORE

  4. 4. Harnessing the power of model systems to investigate regulation of Anaplastic Lymphoma Kinase function

    University dissertation from Umea : Academic Publications
