  1. 11. Simulated and observed change of precipitation and temperature in Europe with focus on the Greater Baltic Area

    Författare :Alexander Walther; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climatology; precipitation; temperature; extremes; thermal growing season; diurnal cycle; regional climate model;

    Sammanfattning : The regional climate of the Greater Baltic Area is complex and varies at a multitude of scales in space and time. This thesis contributes to increased understanding of climate change and climate variability in this area focusing on four significant research topics. Droughts have a considerable ecological and socio-economic impact. LÄS MER

  3. 12. Associations among early-season root and shoot traits, nutrient use efficiency and grain yield of spring wheat

    Författare :Hui Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nutrient-efficient and high-yielding spring wheat is needed in high-latitude regions. The aims of this thesis were: (1) to evaluate the effects of soil compaction and differential weather conditions on plant growth and grain yield, (2) to identify critical nutrient elements limiting plant growth and grain yield, and (3) to identify root and shoot traits at an early growth stage (early vigor) influencing nutrient use efficiency and grain yield of spring wheat.

  4. 13. "Det gör godt att skåda" : bildning, moral och underhållning i dramatik och offentlig debatt under teatersäsongen 1868-69 i Stockholm

    Författare :István Molnár; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Publicistik och teater-- Sverige -- 1868-1869; Teater och publicistik-- Sverige -- 1868-1869; Teater-- historia -- Stockholm -- 1868-1869; Teater-- historia -- Sverige -- 1800-talet; Teaterrepertoar-- Stockholm -- 1868-1869; Teaterpolitik-- Stockholm -- 1868-1869;

    Sammanfattning : The purpuse of this study is to explore the views held on theatre and the idea-content of the theatre-productions during this specific year. The conception of the theatre's role in society is presented on the basis of the debates about theatre held in the parliament and by the press. LÄS MER

  5. 14. Drainage intensity in paddy rice fields : nitrogen flows, salinity, rice yield and greenhouse gas emissions

    Författare :Olive Tuyishime; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Managing drainage intensity is important in controlling soil moisture and nutrient losses and improving crop yields. This thesis evaluated the effects of drainage intensity on nitrogen losses, salinity and rice grain yield in three cropping seasons, and on gaseous emissions of methane (CH4) and nitrous oxide (N2O) from rice flowering to ripening in one season, on a marshland in semiarid region of Rwanda.

  7. 15. Dynamics of Resistant Plasmodium falciparum Parasites

    Författare :Nizar Enweji; Göte Swedberg; Anna Färnert; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Persistence of drug resistant Plasmodium falciparum is a major problem to management and control malaria in endemic areas. The focus of this thesis was to study the dynamics of resistant P. falciparum parasites. LÄS MER
