  1. 36. On Inter-bar Currents in Induction Motors with Cast Aluminium and Cast Copper Rotors

    Författare :Alexander Stening; Chandur Sadarangani; Ola Aglén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction motors; Inter-bar currents; Copper rotors; Aluminium rotors; Starting torque; Asynchronous torques; Starting current; Stray losses; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis presents a study of the effects of inter-bar currents on inductionmotor starting performance and stray-load losses. The work is focused on theperformance differences between aluminium and copper casted rotors.A method to predict the stator current when starting direct-on-line isdeveloped. LÄS MER

    Författare :Linus Larsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; warm sheet metal forming. elevated temperature; aluminium; malgnesiurn. induction heating;

    Sammanfattning : The increasing use of light metals and high strength steel in the automobile industry, demands for new sheet metal forming processes that can be applied successfully. In this thesis the subject of warm sheet metal forming is studied. LÄS MER

  4. 38. Factors of importance for labor induction

    Författare :Tove Wallström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: What initiates the onset of labor is still not clarified, and it is debated whether expectant or active management is the best for the woman and the fetus. Active management means induction of labor (IOL) which is a very common obstetric intervention and is used in several situations. LÄS MER

  7. 40. Cell-penetrating peptides in model membrane systems : Interaction, structure induction and membrane effects

    Författare :Mazin Magzoub; Astrid Gräslund; Steven Dowdy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : Despite continuing advances in the development of macromolecules, including peptides, proteins, and oligonucleotides, for therapeutic purposes, the successful application of these hydrophilic molecules has so far been hampered by their inability to efficiently traverse the plasma membrane. The discovery of a class of peptides (cell-penetrating peptides, CPPs) with the ability to mediate the non-invasive and efficient import of a whole host of cargoes, both in vitro and in vivo, has provided a new means by which the problem associated with cellular delivery can be circumvented.
