    Sammanfattning : In this thesis, electron transport in mesoscopic semiconductor nanostructures, in particular so-called electron billiards or quantum dots, is studied. The thesis can be divided into two areas: the linear response regime of transport, and the nonlinear response regime of transport. LÄS MER

  2. 2. Skriftligt eller muntligt? : Lärares och elevers erfarenheter av återkoppling i ämnet samhällskunskap i gymnasieskolan

    Författare :Anneli Wiker; Hans Lödén; Håkan Löfgren; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Statsvetenskap; Political Science;

    Sammanfattning : This study examines how teachers present feedback in high school social studies, how students understand said feedback, and how feedback can be a tool to help students achieve their goals.  In order to study subject specific feedback it is necessary to observe how teachers link subject material with assessment in their feedback to students.

    Sammanfattning : Non-surgical and surgical approaches to treatment are used in patients with cervical radiculopathy (CR) due to disc disease. Overall, good effects of surgery have been reported on arm pain and neurological symptoms. However, the effects on neck functioning are more uncertain. LÄS MER
