  2. 11. Uniformity in physics courses and student diversity : A study of learning to participate in physics

    Author : Anders Johansson; Staffan Andersson; Minna Salminen-Karlsson; Maja Elmgren; Cedric Linder; Maria Berge; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; undergraduate physics education; science participation; discourse; identity; subject position; quantum physics; electromagnetism; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This licentiate thesis describes an investigation of participation and achievement in undergraduate physics courses with a discourse analytical lens. Issues of unequal participation have been a growing concern for the physics education research community. READ MORE

  4. 12. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Author : Sofia Thorman; Li Yang; Göran Ström; Magnus Lestelius; Janet Preston; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Abstract : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. READ MORE

  5. 13. Compression uniformity measurements on coated anduncoated paper surfaces

    Author : Isabel Endres; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. READ MORE

  6. 14. Extended impregnation kraft cooking of softwood : Effects on reject, yield, pulping uniformity, and physical properties

    Author : Katarina Karlström; Mikael E. Lindström; Elisabet Brännvall; Kristofer Gamstedt; Anna Jacobs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high kappa number pulp; extended impregnation; softwood; spruce; picea abies; pine; pinus sylvestris; uniform delignification; kappa number distribution; reject; yield; tensile index; tensile stiffness index; SCT; starch multilayers; mechano-sorptive creep; hygroexpansion; dimensional stability; eucalypt; birch; acacia; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. READ MORE
