  1. 6. Synthesis, characterization and molecular architecture of electroactive and degradable polymers

    Författare :Baolin Guo; Ann-Christine Albertsson; Anna Finne Wistrand; Ann Cornell; Mark Rutland; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poly L; L-lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; tissue engineering; Polymer chemistry; Polymerkemi;

    Sammanfattning : The third-generation biomaterials are designed to stimulate specific cellular responses at the molecular level. Recent studies have shown that electrical signals regulate cellular activities including cell adhesion, migration, proliferation and differentiation. LÄS MER

  3. 7. Warriors and Worriers : Development, Protective and Exacerbating Factors in Children with Behavior Problems. A Study Across the First Six Years of School

    Författare :Lisbeth Henricsson; Ann-Margret Rydell; Ann Frodi; Uppsala universitet; []
    Nyckelord :Psychology; Externalizing behavior problems; Internalizing behavior problems; Social competence; Self-esteem; Teacher-child relationships; Peer relationships; School achievement; Loneliness; Teacher strategies; Psykologi;

    Sammanfattning : Various aspects of elementary school children's behavior problems were investigated in four studies. In Study I, teachers’ perceived low control over the classroom situation and a custodial teacher orientation were associated with teachers' (n = 86) preferences for authoritarian strategies (e.g. LÄS MER

  4. 8. Upper limb reduction deficiencies in Swedish children : classification, prevalence and function with myoelectric prostheses

    Författare :Liselotte M. N. Hermansson; Ann-Christine Eliasson; Ann Nachemson; Karolinska institutet Institutionen för kvinnors och barns hälsa; Karolinska Institutet; Karolinska Institutet; []

  7. 10. The Assessment of Capacity for Myoelectric Control : Psychometric evidence and comparison with upper limb prosthetic outcome measures

    Författare :Helen Lindner; Liselotte Hermansson; Ann-Christin Eliasson; Ann Langius Eklöf; Helena Burger; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; capacity; comparison; icf; myoelectric control; psychometric evidence; upper limb prosthesis;

    Sammanfattning : Evaluation of outcomes using validated prosthetic outcome measures (OMs) is a current priority in upper limb (UL) prosthetics, and OMs with psychometric evidence toward UL prosthesis users are thus necessary. The “Assessment of Capacity for Myoelectric Control” (ACMC) is a tool that assesses the ability to control a myoelectric prosthetic hand. LÄS MER
