  1. 1. Whiteness and Fluorescence in Layered Paper and Board : Perception and Optical Modelling

    Författare :Ludovic Gustafsson Coppel; Per Edström; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Whiteness; Perception; Colour Appearance Modelling; Paper Optics; Light Scattering; Fluorescence; Lateral Light Scattering; White-Top Mottle; Kubelka-Munk; Radiative Transfer;

    Sammanfattning : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This involves psychophysical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.

  4. 3. Fear of violence and gendered power relations : Responses to threat in public space in Sweden

    Författare :Linda Sandberg; Aina Tollefsen; Malin Rönnblom; Rachel Pain; Umeå universitet; []
    Nyckelord :The geography of fear; gender relations; fear of violence; whiteness; gender equality; masculinity; femininity; narrative analysis; Sweden; Social and Economic Geography; kulturgeografi;

    Sammanfattning : Several cases of single repeat offenders in urban space have raised public concern in Sweden during recent decades. Few studies have been conducted on consequences of the kind of ‘hostage situations’ that emerge when one individual offender causes fear and affects a larger group of people in a specific place.

  5. 4. Paper-composite porcelain : characterisation of material properties and workability from a ceramic art and design perspective

    Författare :Kim Jeoung-Ah; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ceramic art and design; Paper clay; Porcelain;

    Sammanfattning : Paper-composite porcelain is a type of paper clay which is made by combining any kind of porcelain with paper. Paper is added to clay to improve low green strength and plasticity - two of the main practical problems of working with porcelain. LÄS MER

    Sammanfattning : Sexuality education (SE) involves topics that can be perceived as sensitive and private, which creates challenges for teachers. Teachers in Sweden feel uncomfortable with the subject of SE, as they lack knowledge about LGBTQ issues and experience uncertainty in handling charged discussions. LÄS MER
