  2. 22. Lung hyaluronan and lung water in the perinatal period

    Författare :Hans Johnsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; antenatal corticosteroids; antenatal terbutaline; hyaluronan; hyperoxia; lung water; perinatal period; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Sammanfattning : Hyaluronan is an important component of the lung extracellular matrix, with a high capacity for water immobilization, but information on perinatal changes in the lung hyaluronan concentration and their association with changes in the lung water content is limited. In this study, conducted both in rabbit pups and in human infants, we investigated changes in the hyaluronan concentration and distribution in the lung and in the lung water content after preterm or term birth, and changes produced by common antenatal and postnatal pathological conditions and treatments.

  3. 23. Plug shear failure in nailed timber connections : avoiding brittle and promoting ductile failures

    Författare :Helena Johnsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Mechanical timber connections can fail both in a brittle and a ductile manner depending on the joint layout. Plug shear failure in nailed timber connections is a brittle failure mode, which shall be avoided in timber structures. LÄS MER

  4. 24. Systematic design of glulam trusses

    Författare :Helena Johnsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The design of a structure should be regarded as the design of a system. In this licentiate thesis a method (concurrent engineering) for the design of systems is studied parallel with the development of the system itself. LÄS MER
