    Abstract : I denna avhandling visar jag hur elever och lärare genomför NO-verksamhet i grundskolan. Avhandlingen illustrerar hur elevers frågor och uttryckta erfarenheter blir en del av ett etablerat ämnesinnehåll. READ MORE

  5. 3. Measurement and modelling of unbalanced magnetic pull in hydropower generators

    Author : Mattias Wallin; Urban Lundin; Antero Arkkio; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Damper winding; eddy currents; field winding short circuit; finite element method; hydropower generator; parallel circuits; rotor eccentricity; salient poles; synchronous generators; synchronous machines; UMP; unbalanced magnetic pull.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Hydropower research is often perceived to be an old and exhausted field of study but with ageing equipment and the need for more intermittent operation caused by an increased share of other renewable energy sources new challenges lie ahead.The main focus of this dissertation are the electromagnetic forces resulting from nonuniform air gap flux, whether it be caused by rotor eccentricity or a faulty field winding.

  6. 4. QED and collective effects in vacuum and plasmas

    Author : Joakim Lundin; Mattias Marklund; Thomas Heinzl; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; QED; quantum electrodynamics; quantum plasmas; quantum vacuum; Plasma physics; Plasmafysik; fysik; Physics;

    Abstract : The theory of quantum electrodynamics (QED) was born out of an attempt to merge Einsteins theory of special relativity and quantum mechanics. Einsteins energy/mass equivalence together with Heisenberg's uncertainty principle allows for particle pairs to be spontaneously created and annihilated in vacuum. READ MORE

  7. 5. Exploring the complexities of integrating socioscientific issues in science teaching

    Author : Ulrika Bossér; Mats Lindahl; Mattias Lundin; Cedric Linder; Christina Ottander; Linnéuniversitetet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Scientific literacy; Socioscientific issues; Secondary school science; Teacher reflection; Classroom discourse; Science Education; Naturvetenskap med utbildningsvetenskaplig inriktning;

    Abstract : Socioscientific issues, SSI, can briefly be described as societal issues in which science plays a role. Dealing with SSI in science education is a means to prepare and empower students for active and responsible participation in a complex, democratic society. READ MORE
