  1. 11. Conceptual Runoff Models for Material Transport Estimations

    Författare :Rikard Lidén; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; Conceptual Rainfall-Runoff Modelling; Riverine Material Transport; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : Catchment-scale material transport models are today important tools for water and environmental management. However, modelling of material transport is extremely complex due to the physical, chemical and biological processes involved. LÄS MER

  3. 12. Riverine nitrogen : Analysis and modelling under Nordic conditions

    Författare :Berit Arheimer; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The Baltic Sea in northern Europe is a brackish water body where eutrophication is considered a serious problem, partly as a result of high nitrogen load from rivers. This thesis includes statistical analysis of nitrogen behaviour in 55 small catchments. The results were used for further development of a dynamic model (HBV-N). LÄS MER

  4. 13. Improving immunogenicity of hepatitis B and C viral proteins for vaccine design

    Författare :Antony Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The hepatitis B and C virus (HBV, HCV) both presents a global health challenge, with an estimated 350 million individuals chronically infected with HBV and over 200 million infected with HCV. Reported cases of HBV and HCV have declined significantly due to screening of blood products and the availability of HBV vaccination. LÄS MER

  5. 14. The hepatitis B virus – Insights into genetic variability, evolution and Bayesian phylogeographic inference

    Författare :Mikael Ingman; Malmö Klinisk virologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatit B; evolutionsbiologi; fylogeni; Hepatitis B; evolutionary dynamics; Phylogeography;

    Sammanfattning : In terms of genome size, the hepatitis B virus is the smallest virus known to infect humans and its compactness with multiple overlapping reading frames puts restraints on the emergence of mutations. In the papers included in this thesis we aimed to investigate genetic variation within the precore and core promoter region and to describe the origin, spread and diversification of HBV genotype A.

  7. 15. Characterisation of the interaction between the Hepatitis B virus core antigen and B cells

    Författare :Una Lazdina; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HBcAg; B cells; B cell antigen receptor; co-stimulatory molecules; cytokines; T helper cells; cytotoxic T cells;

    Sammanfattning : The Hepatitis B virus (HBV) is a major cause of severe human liver disease globally. There are around 350 million persistent HBV carriers with a risk of development of liver disease including cirrhosis and hepatocellular carcinoma. LÄS MER
