  1. 1. CD8+ T cell specificity in thymic selection and in the recognition of antigen

    Författare :Johan Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :T cell; specificity; MHC class 1; selection; tolerance;

    Sammanfattning : Specificity mediated by the T cell receptor (TCR) is of fundamental importance for the ability of T cells to function, and regulate humoral immunity and effector mechanisms of the innate immune system. T cells recognize composite molecules consisting of products of the major histocompatibility complex (MHC) class I or class 11 loci, in complex with a short peptide fragment derived from endogenous or antigenic proteins.

  3. 2. B cell responses to human flavivirus vaccination and SARS-CoV-2 infection

    Författare :Tyler Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Viral infections pose a major threat to global heath. As specific antiviral treatments are lacking against many human viruses, vaccination is the most effective medical intervention to prevent severe disease and death. Delineating the immune events following viral vaccination and infection can help in the design of new vaccines and therapeutics. LÄS MER

  4. 3. Novel Approaches to ECG-Based Modeling and Characterization of Atrial Fibrillation

    Författare :Frida Sandberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMM; ECG; Biomedical Signal Processing; Time-Frequency Analysis; Atrial Fibrillation; Sample Entropy; AV modeling;

    Sammanfattning : This thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. LÄS MER

  5. 4. Norway spruce heartwood : properties related to outdoor use

    Författare :Karin Sandberg; Lars-Olof Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). LÄS MER

  7. 5. Design for manufacturing : methods and applications using knowledge engineering

    Författare :Marcus Sandberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development;

    Sammanfattning : As companies strive to develop artefacts intended for services instead of traditional sell-off, new challenges in the product development process arise to promote continuous improvement and increasing market profits. This creates a focus on product life-cycle components as companies then make life-cycle commitments, where they are responsible for the function availability during the extent of the life-cycle, i.
