  1. 1. Accumulation from Below : Smallholders and public irrigation investments in Kilombero Valley, Tanzania

    Författare :Victor Mbande; Lowe Börjeson; Johan Berg; Liwenga Liwenga; Klara Fischer; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accumulation; social differentiation; wealth ranking; irrigation; smallholders; agriculture transformation; land use change; rice boom; progressive farmers; development; geografi med kulturgeografisk inriktning; Geography with Emphasis on Human Geography;

    Sammanfattning : Smallholders in Tanzania and elsewhere in Africa are increasingly differentiated. This thesis contributes to the empirical and conceptual understanding of the differentiation processes in irrigation by following the internal dynamics among smallholders linked to public investments in improving smallholder initiated small scale irrigation schemes in Kilombero district, Tanzania.

  3. 2. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet

    Författare :Charalampos Charalampidis; Veijo Pohjola; Dirk van As; Rickard Pettersson; Douglas Benn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland ice sheet; accumulation area; automatic weather stations; surface energy balance; melt–albedo feedback; surface mass budget; snow; firn; meltwater; percolation; refreezing; runoff;

    Sammanfattning : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. LÄS MER

  4. 3. Cytokines and Neutrophils in the Urinary Tract Mucosa

    Författare :Long Hang; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; neutrophils; chemokines; urinary tract infection; mucosa; epithelial cells; serology; transplantation; Immunologi; serologi;

    Sammanfattning : This study investigated the urinary tract cytokine reponse to infection and the role of chemokines for neutrophil recruitment to the urinary tract. The results suggest that 1) IL-8 and TGFb are consitutively produced by uroepithelial cells in vivo, and that uroepithelial cells are stimulated to produce IL-1b and IL-6 by uropathogenic Escherichia coli.

  5. 4. Bacterial antibody hydrolyzing enzymes – as bacterial virulence factors and biotechnological tools

    Författare :Eleni Bratanis; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunoglobulins; Immunomodulation; Antibody mediated immunity; Glycosylation; Bacterial virulence; Bacterial enzymes; Biotechnology; streptococcus pyogenes; Bdellovibrio bacteriovorus;

    Sammanfattning : Antibodies are an essential part of the human immune system, and antibody mediated immunity has been an area of interest for many researchers for almost a century. An accumulation of knowledge regarding antibody structure, glycosylation and receptor interactions has contributed to the current understanding of antibody mediated immunity. LÄS MER

  7. 5. Berries in Prevention of Metabolic Disease – focus on obesity, diabetes and gut microbiota

    Författare :Lovisa Heyman; Molekylär nutrition; []
