    Sammanfattning : This study is based on the presumption that language is fundamental to the construction of knowledge. In addition, linguistic demands are incorporated in the policy documents of the upper secondary edu­cation of Sweden; students shall, during their education, be given the opportunity to appropriate certain linguistic tools.

    Nyckelord :HUMANIORA; HUMANITIES; Worship community; ecclesiological concretion; ecclesiologial balance contextually sensitive; historically rooted and confessionally widened ; corporate person; ideal types; ecclesiological subject hidden; visible and structuring ; ecclesiological core values and ecclesiological basic qualities.;

    Sammanfattning : The dissertation examines the theoretical identity and formal status of a worship community within the Church of Sweden. Two theoretical perspectives form the basis of the investigation. LÄS MER

  3. 3. Advanced nano- and microdomain engineering of Rb-doped KTiOPO4 for nonlinear optical applications

    Författare :Charlotte Liljestrand; Carlota Canalias; Sunao Kurimura; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; KTiOPO4; nonlinear optics; MOPO; quasi-phase matching; SHG; ferroelectrics; domain structuring; periodic poling; Physics; Fysik;

    Sammanfattning : Fine-pitch ferroelectric domain gratings are extensively used for generation of light in the visible and near-infrared spectral regions through quasi-phase matched (QPM) frequency conversion. Sub-μm QPM devices enables demonstration of nonlinear optics with counterpropagating waves, a field of nonlinear optics which remains sparsely explored due to the difficulty of fabricatinghigh quality gratings.

  4. 4. Multi-spectral analysis of fine scale aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Fred Sigernes; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik; Optics; Optik;

    Sammanfattning : The Aurora Borealis is the visible manifestation of the complex plasma interaction between the solar wind and the Earth's magnetosphere and ionosphere. Ground based and in situ measurements demonstrate a prevalence of dynamic fine structure within auroral displays, with spatial scales down to tens of metres and time variations occurring on a fraction of a second.

  5. 5. Ferroelectric domain engineering and characterization for photonic applications

    Författare :Simonetta Grilli; Fredrik Laurell; Wolfgang Sohler; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; LiNbO; KTiOPO; interferometry; digital holography; electric field poling; electro-optic materials; holographic lithography; ferroelectric domains; nanostructures; microstructures; Optical physics; Optisk fysik;

    Sammanfattning : Lithium niobate (LiNbO3) and KTiOPO4 (KTP) are ferroelectric crystals of considerable interest in different fields of optics and optoelectronics. Due to its large values of the nonlinear optical, electro-optic (EO), piezoelectric and acousto-optical coefficients, LiNbO3 is widely used for laser frequency conversion using the quasiphase matching (QPM) approach where the sign of nonlinearity has been periodically modulated by electric field poling (EFP).
