Diagnostic information for these tissues is manifest in textural and geometric features of the OCT images, which are used by human expertise to interpret and triage. However, it suffers delays due to the long process of ...
    • Språkleg toleranse i Noreg: Norge, for faen! 

      Vangsnes, Øystein Alexander (Book; Bok, 2013)
      Er vi nordmenn eigentleg så språktolerante som vi likar å tru? Blant språkforskarar utanlands blir Noreg sett på som eit land med stor takhøgd for språkleg mangfald. Men i kva grad set eigentleg det norske folket pris på språkmangfald? Kvifor ser ein stadig negative og til dels hatske utfall mot nynorsk? Kvifor møter meir synleggjering av samisk språk i Nord-Noreg sterk folkeleg motstand? Er det ...
