  2. 16. Nanocelluloses - surface modification and use in functional materials

    Author : Michaela Salajková; Lars Berglund; Gunnar Westman; Anna Finne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose; surfactant; surface modification; papermaking process; quaternary ammonium salt;

    Abstract : Cellulose nanocomposites offer interesting potential in terms of improved properties and new functionalities compared with microcomposites. Preparation from colloidal suspensions is promising, since high reinforcement content is possible and a wide range of constituents can be used. READ MORE

  4. 17. Iron absorption in man - diet modification and fortification

    Author : Michael Hoppe; Göteborgs universitet; []
    Keywords : Iron absorption; Serum iron; Relative bioavailability; Elemental iron; Iron bioavailability; Iron fortification; Dietary modification; Developing countries;

    Abstract : Background: Iron (Fe) deficiency is globally the most common form of nutrient deficiency. The approach to combat this problem can be divided into two major strategies a): increasing the dietary Fe bioavailability by diet modification, or b): increasing the Fe intake through fortification.

  5. 18. Plasma Modification of Polypropylene Materials for Improved Adhesion

    Author : Anna Nihlstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polypropylene; characterization; material composition; lacquer adhesion; plasma modification; chain scission; vacuum-ultraviolet radiation; thermoplastic polyolefin;

    Abstract : Materials based on PP are widely used in industrial applications. To fulfil application demands, components must often be lacquered, printed or glued. As PP is highly unreactive and presents a low surface energy, a pretreatment that can promote bondability is necessary. READ MORE

  6. 19. Older people's home modification process

    Author : Karin Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ageing in place; agency; client-centred; empowerment; possibilities for action; home modifications; occupational therapy; older people; place integration; practical rationalities; service organisation;

    Abstract : The overall aim of the thesis was to provide theoretical and empirical knowledge of interactions involved in the encounters between older persons experiencing activity limitations in their home environments and the service organisation related to home modification services, in the context of one Swedish municipality. A transactional perspective was used, meaning that the focus was on driving forces and relationships connecting different aspects and actors involved in older people s encounters with the service organisation related to home modification services.

  7. 20. On Prosodic Modification of Speech

    Author : Barbara Resch; Bastiaan Kleijn; Thomas Eriksson; KTH; []
    Keywords : ;

    Abstract : Prosodic modification has become of major theoretical and practical interest in the field of speech processing research over the last decades. Algorithms for time and pitch scaling are used both for speech modification and for speech synthesis. READ MORE
