  1. 16. Infections with HIV-1 and mycobacterium tuberculosis : the role of HLA class II alleles and HIV phenotypes

    Författare :Simani Gaseitsiwe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human Immunodeficiency Virus (HIV) and Mycobacterium tuberculosis (M.tb), are the two infectious diseases causing the greatest number of deaths globally. The burden of these infections is most felt in the developing world particularly in sub-Saharan Africa. This is also a region where some of the studies in this thesis were conducted. LÄS MER

  3. 17. Genetic, morphological and chemical variation in the genus Harpagophytum

    Författare :Mbaki Muzila; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Harpagophytum procumbens is a valuable medicinal plant but mistakes with plant identification at harvesting, and wilful adulteration using the presumably less efficient H. zeyheri are suggested. A multidisciplinary study with plant material from Botswana was conducted. LÄS MER

  4. 18. Auditing the African State. International Standards and Local Adjustments

    Författare :Maria Gustavson; Göteborgs universitet; []

  5. 19. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS

    Författare :Andreas Gyllenhammar; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; scales; marine fish farms; rainbow trout; nutrients; suspended particulate matter; phosphorus; nitrogen; GIS; basin delineation; regionalisation; coastal areas; aquatic foodweb; fishing quotas; Baltic Sea; Archipelago Sea; Okavango Delta; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : This thesis presents models applicable for aquatic ecosystems. Geographical Information Systems (GIS) form an important part of the thesis. The dynamic mass balance models focus on nutrient fluxes, biotic/abiotic interactions and operate on different temporal and spatial scales (site, local, regional and international). LÄS MER

  7. 20. Prevention of Mother to Child Transmission of HIV in Africa : Operational Research to Reduce Post-natal Transmission and Infant Mortality

    Sammanfattning : This thesis assesses the effectiveness of the National Prevention of Mother to Child Transmission of HIV (PMTCT) programme in 3 sites in South Africa, and the quality of infant feeding counselling across four countries, Botswana, Kenya, Malawi and Uganda . Implementation and outcome of PMTCT services were very different across the 3 sites. LÄS MER
