  1. 1. Controlling the Pore Size and Morphology of Mesoporous Silica

    Författare :Emma M. Johansson; Magnus Odén; José M. Cordoba; Niklas Hedin; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Mesoporous silica with a hexagonally ordered pore structure (SBA-15) has been synthesized. Through variations in the synthesis conditions several morphologies, such as fibers, sheets and separate rods, have been realized. LÄS MER

  3. 2. Oxygen-reducing enzymes in coatings and films for active packaging

    Författare :Kristin Johansson; Lars Järnström; Caisa Johansson; Leif J. Jönsson; Jose M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active packaging; food packaging; oxygen scavengers; oxygen-reducing enzymes; dispersion coating; biopolymers; Chemical Engineering; Kemiteknik;

    Sammanfattning : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. LÄS MER

  4. 3. Interventions for urinary incontinence in women : survey and effects on population and patient level

    Författare :Karin Franzén; Kerstin Nilsson; Jan-Erik Johansson; Ian Milsom; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary incontinence; female; general living conditions; self-management; electrical stimulation; quality of life questionnaire; MEDICINE; MEDICIN; Surgery; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : Urinary Incontinence is a common health problem that can cause both severe medical and social problems, resulting in negative impact on different aspects of Quality of Life. In 2000, the Swedish Council on Health Technology Assessment (SBU) published a systematic review, “Treatment of Urinary Incontinence” where multiple knowledge gaps in the field of UI, all of considerable clinical importance, were pointed out.
