  1. 16. Image processing methods to study the living hearing organ

    Författare :Miriam von Tiedemann; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis we are developing image processing methods allowing one to probe the structure and function of the mammalian hearing organ, an intricate cellular assembly with a highly specialized three-dimensional organization. Confocal as well as electron microscopy was used for image acquisition. LÄS MER

  3. 17. On Hardware Implementation of Discrete-Time Cellular Neural Networks

    Författare :Suleyman Malki; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit switching; Network on Chip; Vein feature extraction; Velocity measurement; Discrete-Time Cellular Neural Network; Switched broadcast; Serialized broadcast; Cellular Neural Network; Field- Programmable Gate-Array; Image processing.;

    Sammanfattning : Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. LÄS MER

  4. 18. Control of Epstein-Barr virus infection by cytotoxic T lymphocytes

    Författare :Pedro-Otavio de Campos-Lima; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Epstein-Barr virus; Cytotoxic T lymphocytes; T cell receptor; CTLescape mutants;

    Sammanfattning : Cytotoxic T lymphocytes (CTL) play a critical role in response to Epstein-Barr virus (EBV), a widespread human herpes virus that persists in healthy carriers as a latent infection of B cells and is implicated in the pathogenesis of lymphoid and epithelial cell malignancies. Six virus encoded nuclear antigens, EBNA1-6, and three membrane proteins, LMP1, -2A and -2B, are regularly detected in EBV transformed lymphoblastoid cell lines (LCLs). LÄS MER

  5. 19. Colour Calibration of Trichromatic Capturing Devices

    Författare :Mattias Andersson; Olle Inganäs; Nir Tessler; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer; fullerene; field-effect transistor; solar cell; electrical transport; mobility; Physics; Fysik;

    Sammanfattning : In a time where there is an increasing demand for easily accessible and up-to-date information, digital printing has become a link between traditional printed media and electronic media. Over the last years, applications such as variable data printing, personalised printing and print on demand have changed the way in which printed matter is produced and handled. LÄS MER

  7. 20. Vector development for suicide gene therapy

    Författare :Alar Aints; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Suicide gene therapy; VP22; selection markers; Ouabain resistance gene; GvHD; retroviral gene transfer;

    Sammanfattning : Gene therapy is used to treat conditions that arise from errors in the genetic makeup of cells either congenital diseases resulting from a deletion or mutation in a gene or malignant diseases where genetic regulation mechanisms have been deranged. Suicide gene therapy is one of several gene therapeutic approaches to treat cancer. LÄS MER
