  1. 21. Systematic design of glulam trusses

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

    Abstract : 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. READ MORE

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

    Author : Hans Johnsson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. Sterically stabilised liposomes and related lipid aggregates : Fundamental studies on aggragate structure and stability

    Author : Markus Johnsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; liposome; steric stabilisation; colloidal stability; cryo-TEM; drug delivery; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : Various aspects of and approaches towards the steric stabilisation of liposomes have been investigated, mainly by use of fluorescence techniques and cryo-transmission electron microscopy (cryo-TEM). It is shown that PEG(2000)-lipids can be incorporated in the liposome membrane up to a critical concentration of 8-10 mol% without any observable structural perturbations. READ MORE

  4. 24. The human-computer interface in commercial systems : Investigations of dialogue design factors and usability with alphanumeric display terminals

    Author : Bengt Johnsson; Bertil Andersson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; administrative process; administrative system; commercial system; controlled experimentation; criteria; design property; display terminal; field investigation; human-computer interface; man-computer dialogue; man-machine matching; terminal user; usability; Information Systems; Informatik;

    Abstract : When terminal based computer systems are incorporated in administrative processes, man-computer interface technology for many reasons becomes a crucial problem area. Terminal users ("terminalists") in such systems account for a vast number of terminal hours. READ MORE

  5. 25. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

    Author : Eskil Johnsson; Institutionen för laboratoriemedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

    Abstract : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. READ MORE
