  1. 1. Early life exposures and lung function development

    Författare :Björn Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : BACKGROUND: Lung development is a dynamic process, vulnerable to adverse environmental exposures. Starting in utero, development continues postnatally, and although lung structure is mainly set at around two years of age, the maturation process continues into young adulthood. LÄS MER

  2. 2. Naturliga medborgare : Friluftsliv och medborgarfostran i scoutrörelsen och Unga Örnar 1925-1960

    Författare :Björn Lundberg; Forskarskolan i historia; []
    Nyckelord :HUMANIORA; HUMANITIES; friluftsliv; medborgarskap; scouting; Unga Örnar; läger;

    Sammanfattning : The aim of this thesis has been to examine outdoor activities and camping, framed within the Scandinavian notion of friluftsliv, as methods for promoting citizenship in two Swedish youth organisations: the Scout movement and Unga Örnar (“Young Eagles”). What knowledge and abilities characterised ideal citizenship; how was instruction in citzenship for children conducted and more specifically, how were nature and friluftsliv employed as resources to accomplish training for citizens? The results of this study show that friluftsliv as an educational method in these organisations, most notably in the Scout organisations, reflected ideas about active citizenship understood as civic, everyday practice.

  3. 3. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Sammanfattning : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. LÄS MER

  4. 4. Parameter Estimation of a DOC from Engine Rig Experiments

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Data Analysis; Parameter Estimation; Exhaust Aftertreatment Modeling; Design of Experiments; Engine Test Bench; DOC; Full Scale;

    Sammanfattning : In this thesis methods of parameter estimation of a Diesel Oxidation Catalyst (DOC) from engine rig experiments were investigated. The investigation did not only include methods of parameter fitting to experimental data but a large effort was also put into catalyst modeling and experimental design. LÄS MER

  5. 5. Safety and efficacy of intracameral mydriatics in cataract surgery

    Författare :Björn Lundberg; Anders Behndig; Charlotta Zetterström; Umeå universitet; []
    Nyckelord :Ophtalmology; intracameral; mydriatics; pupil; cataract; phacoemulsification; lidocaine; phenylephrine; cyclopentolate; epinephrine; endothelial cell loss; Oftalmiatrik; oftalmiatrik; Ophtalmology;

    Sammanfattning : Background: In order to perform cataract surgery, adequate dilatation of the pupil is essential. This is traditionally achieved by preoperative topical mydriatic eye-drops, commonly cyclopentolate and phenylephrine. This routine has several disadvantages. First, the slow penetration through the cornea delays the onset of mydriasis. LÄS MER
