    Sammanfattning : The aim of the present study is, firstly, to investigate the amount of Swedish and French that is produced by teachers and students in the foreign language classroom and, secondly, to examine in which situations the interlocutors code-switch and for what purposes the two languages are used. The study is based on empirical data consisting of audio recordings of interactions taking place in two different classrooms in Sweden. LÄS MER

  3. 2. On soft-switching isolated AC/DC converters without auxiliary circuit

    Författare :Staffan Norrga; Stefan Östlund; Rik De Doncker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; voltage source converter; cycloconverter; isolated converter; medium frequency transformer; soft switching; modulation; commutation; wind power; electric traction; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Sammanfattning : The thesis is concerned with a class of power electronic converter systems that permit bidirectional AC/DC conversion with galvanic separation of the AC and DC sides by a transformer operating at elevated frequency. The systems consist of a capacitively snubbered voltage source converter and a cycloconverter, separated by the mentioned transformer. LÄS MER

    Sammanfattning : The development of immature progenitor cells into highly differentiated effector cells is a process central in modern medicine with applications in the fields of cell therapy as well as oncology. This thesis is focused on the molecular mechanisms that control the development of B lymphocytes. LÄS MER

  5. 4. Immunoglobulin isotype switching in health and disease

    Författare :Berivan Baskin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Immunoglobulin isotype switching is the process where the Cmy region, initially located downstream of the VDJ region is replaced by another constant region gene. Class switch recombination takes place between switch (S) regions, composed of tandem repeats of short unit sequences, located 5 of each CH gene, except for Cdelta. LÄS MER
