  1. 1. Vegetation changes on Swedish mires : Effects of raised temperature and increased nitrogen and sulphur influx

    Författare :Urban Gunnarsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Acidification; growth; long-term studies; mires; nitrogen; species richness; Sphagnum; succession; sulphur; temperature; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Since the start of the industrialisation, the deposition of nitrogen and sulphur and the atmospheric concentrations of greenhouse gases have increased. The main objectives of this study were to find how these changes in climate and deposition can change the vegetation of mire ecosystems and the growth of Sphagnumspecies. LÄS MER

    Sammanfattning : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. LÄS MER

  4. 3. Towards Better Urban Spaces in Harmony with Microclimate: Urban design and planning regulations in hot dry Damascus, Syria

    Författare :Moohammed Wasim Yahia; Boende och bostadsutveckling; []
    Nyckelord :HUMANIORA; HUMANITIES; Architecture; Arid zones; Built environment; Climate; Climatic design; Damascus; Hot dry regions; Landscape elements; Microclimate; Planning regulations; Thermal comfort; Thermal indices; Urban climate; Urban design; Urban planning;

    Sammanfattning : This research is an attempt to develop further understanding of the relationship between microclimate, thermal comfort, urban design and outdoor space users in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in Damascus. LÄS MER

  5. 4. Microclimate and Thermal Comfort of Urban Spaces in Hot Dry Damascus- Influence of urban design and planning regulations

  7. 5. Infective Endocarditis : aspects of pathophysiology, epidemiology, management and prognosis

    Författare :Christer Ekdahl; Rolf Maller; Mats Broqvist; Urban Forsum; Lennart E. Nilsson; Rune Andersson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiology; Infective endocarditis IE ; heart valve surgery; monocytes; granulocytes; staphylococ; Epidemiology; Epidemiologi;

    Sammanfattning : Infective endocarditis (IE) is a rare but complex disease that is fatal if untreated. With a modern combination of antimicrobial therapy and heart valve surgery, mortality is still 10-20 %. The structure of the endocarditis vegetation impedes the penetration of phagocytic cells such as monocytes and granulocytes. LÄS MER
