  1. 1. Frictional studies and high strain rate testing of wood under refining conditions

    Författare :Birgitta Svensson; Hans Höglund; Per A. Gradin; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; High strain rate testing; Wood; Mechanical pulping; Tribology; Refining; Energy consumption; Chemical engineering; Kemiteknik;

    Sammanfattning : When producing thermomechanical pulps (TMP), wood chips and fiber material are loaded mechanically in a disc-refiner to separate the fibers and to make them flexible. In the process, much of the energy supplied is transferred to the fiber material through cyclic compression, shear and friction processes. LÄS MER

  3. 2. Health-related quality of life and everyday life for children with right ventricular outflow tract anomalies. Perspectives from children and parents

    Författare :Birgitta Svensson; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HRQoL; Everyday life; Children; Parents; Congenital heart disease; RVOT anomalies; Heart surgery; Thematic analysis;

    Sammanfattning : Background: Children with right ventricular outflow tract (RVOT) anomaliestypically undergo surgical repair during their first months of life and thereafter they will need one or more reoperations through their life.Aims: The overall aim was to describe health-related quality of life (HRQoL) forchildren with congenital heart disease (CHD) with a special focus on children withRVOT anomalies and to explore children’s and their parents’ experiences ofeveryday life during assessment that could result in a new heart surgery.

    Sammanfattning : This thesis deals with financial accounting information useful for creditors assessing SME creditworthiness. The literature describes financial accounting as a multi-paradigm science having several theoretical schools. LÄS MER

  5. 4. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure

    Författare :Birgitta Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; lyotropic; thermotropic; SANS; SAXS; scattering; semicrystalline; reverse micelle; micellar solution; liquid crystalline; phase diagram; phase behaviour; block copolymer; pluronic; poly ethylene oxide ; poly propylene oxide ; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. LÄS MER

  7. 5. Barn som riskerar att fara illa i sin hemmiljö : Utmaningar i ett förebyggande perspektiv

    Författare :Birgitta Svensson; Staffan Janson; Ulla-Britt Eriksson; Henrik Andershed; Carl-Göran Svedin; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Children at risk of maltreatment; Child abuse; prevention; pre-school; chronic health condition; disabilities; detection; support; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : BaksidestextBarnmisshandel är ett omfattande folkhälsoproblem med långsiktiga negativa konsekvenser för den enskilda individen och för samhället i stort. Förebyggande insatser kan vara livsavgörande för de utsatta barnen. LÄS MER
