  1. 6. Long-term follow-up in children born with congenital diaphragmatic hernia

    Författare :Elin Öst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Congenital diaphragmatic hernia (CDH) is a developmental defect which occurs in approximately 1 per 3000 births. The incomplete development of the diaphragm early in gestation allows abdominal viscera to herniate into the thoracic cavity. The malformation differs in size and can occur on either one or both sides, but most commonly on the left. LÄS MER

  3. 7. Assessment of Long-Term Losses in Prestressed Concrete Structures - Application for Nuclear Reactor Containments

    Författare :Peter Lundqvist; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; KstrConcrete; Nuclear reactor containments; prestressed concrete; prestress losses; bonded tendons; creep; shrinkage; relaxation; prediction models; resonance frequency; acoustoelasticity.;

    Sammanfattning : Most nuclear reactors, both in Sweden and worldwide, are enclosed by a prestressed concrete containment. The main purpose of the containment is to prevent any radioactive discharge to the environment in the event of a major internal accident. LÄS MER

  4. 8. Costs in the ecology and evolution of the vertebrate immune system

    Författare :Lars Råberg; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cost of resistance; ecological immunology; immunocompetence; Parus caeruleus; transgenic mice; Animal ecology; Djurekologi; blue tit; basal metabolic rate;

    Sammanfattning : A central assumption of theories of the ecology and evolution of immunological defence is that defence has not only benefits (in the form of resistance against parasites), but also costs. The aim of my studies was to investigate the nature and magnitude of costs of the vertebrate immune system, and to examine some of the consequences of these costs. LÄS MER

  5. 9. An epidemiologic approach to disorders in the neck and shoulders

    Författare :Kerstin Ekberg; Töres Theorell; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Complaints about pain in the locomotor system represent a commonly occuning health problem among working people all over the world. In this context, a series of studies were employed to determine if work organization and psychosocial conditions at work, in addition to physical work load, contribute to the development of disorders in the neck and shoulders.

  7. 10. Rehabilitation following bone-patellar tendon-bone graft ACL reconstruction

    Författare :Christina Mikkelsen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ACL injury; ACL reconstruction; ACL rehabilitation; Anterior knee laxity; Closed kinetic chain; Extension deficit; Functional outcome score; Gender; Hyperextension brace; Isokinetic open kinetic chain; KOOS; KT-1000 arthrometer; Patello femoral pain; Personality characteristics; Physical activity; Quadriceps torque; Range of motion;

    Sammanfattning : The overall purpose of this Thesis was to improve treatment and rehabilitation after anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone graft. Study I: The purpose of this study was to evaluate and compare closed kinetic chain (CKC) training and a combination of closed and open kinetic chain (OKC) quadriceps exercises following ACL reconstruction on anterior knee laxity and isokinetic muscle torque.
