  2. 6. Beyond averages – some aspects of how to describe a heterogeneous material, mechanical pulp, on particle level

    Author : Olof Ferritsius; Birgitta A. Engberg; Per Engstrand; Mats Rundlöf; Øyvind Weiby Gregersen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Visualisation; Uniformity; Distributions; Independent common factors; Weighted fibre length; Fibre bonding; Fibrillation; Curl; Wall thickness; Particle analyser characterisation; Raw material; CTMP; Process configuration; Sampling accuracy;

    Abstract : For a more profound understanding of how a process works, it is essential to have a relevant description of the material being processed. With this description, it will be easier to evaluate and control processes to produce more uniform products with the right properties. READ MORE

  4. 7. Learning Computing at University: Participation and Identity : A Longitudinal Study

    Author : Anne-Kathrin Peters; Arnold Pears; Anders Berglund; Anna Eckerdal; Lars Ulriksen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computing education research; engineering education research; computer science; higher education; engagement; diversity; equity; gender; competencies; culture; longitudinal; identity; participation; power; agency; uniformity; communities of practice; social theory of learning; phenomenography; student reflections; Datavetenskap med inriktning mot datavetenskapens didaktik; Computer Science with specialization in Computer Science Education Research;

    Abstract : Computing education has struggled with student engagement and diversity in the student population for a long time. Research in science, technology, engineering, and mathematics (STEM) education suggests that taking a social, long-term perspective on learning is a fruitful approach to resolving some of these persistent challenges.

  6. 9. Through air drying : Thermographic studies of drying rates, drying non-uniformity and infrared assisted drying

    Author : Aron Tysén; Lars Nilsson; Shri Ramaswamy; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Through air drying; TAD; Drying; Dewatering; Water removal; Infrared drying; Non-uniformity; Variability; Formation; Thermography; Tissue; Fabric; Wire; Pulp; Grammage; Chemical Engineering; Kemiteknik;

    Abstract : The removal of water is an integral part of papermaking. The drying process is responsible for a great share of the energy used in the paper machine. Premium grade tissue products are dried by through air drying. Large volumes of natural gas are burned to heat the air drawn through the paper web to achieve the drying. READ MORE
