  1. 1. Modelling and Quality Assessment of Atrial Fibrillatory Waves

    Författare :Mikael Henriksson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECG; signal processing; atrial fibrillation; signal quality; catheter ablation; atrial fibrillatory waves; f-waves;

    Sammanfattning : This doctoral thesis revolves around the analysis of electrocardiogram (ECG) signals during atrial fibrillation (AF). Special emphasis is put on the atrial fibrillatory waves, sometimes called the f-waves, which is the ECG component reflecting the electrical activity of the atria. LÄS MER

  3. 2. Arkeologiska förväntningar i mötet med ett landskap : Stenålderns Blekinge ur ett kunskapsperspektiv

    Författare :Mikael Henriksson; Kerstin Cassel; Björn Nilsson; Larsson Åsa M.; Södertörns högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; Blekinge; Listerlandet; South East Sweden; Stone Age archaeology; museum archaeology; Mesolithic huts; Mesolithic houses; Kongemose culture; Archaeology; North European; Arkeologi; nordeuropeisk; Historical Studies; Historiska studier;

    Sammanfattning : This study is about archaeological knowledge production. It is also about what kind of impact such knowledge may have on an antiquarian/archaeological practice as well as on society as a whole. The work focuses broadly on Stone Age archaeology and specifically on the middle-Mesolithic Age in the county of Blekinge in the South East of Sweden. LÄS MER

  4. 3. Molecular aspects of proinsulin C-peptide interactions

    Författare :Mikael Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diabetes mellitus; proinsulin C-peptide;

    Sammanfattning : Insulin biosynthesis in the beta-cells of the pancreas begins with the generation of preproinsulin, which is converted to proinsulin. Proinsulin is cleaved into equimolar amounts of insulin and connecting peptide (C-peptide), which are released into the circulation. LÄS MER

  5. 4. Strategies for improving kraftliner pulp properties

    Författare :Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. LÄS MER

  7. 5. The Use of Lignin Derivatives to Improve Selected Paper Properties

    Författare :Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Docent Roland Agnemo Tek. Dr. Harald Brelid; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; black liquor; cross-flow filtration; lignin derivative; kraftliner; oxidative coupling; laccase; manganese; linseed oil; mechano-sorptive creep; kraftlignin; svartlut; tvärsflödesfiltrering; ligninderivat; kraftliner; oxidativ koppling; lackas; mangan; linolja; mekanosorptivt kryp; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. LÄS MER
