  1. 31. The power of character : Middle-class masculinities, 1800–1900

    Författare :David Tjeder; Arne Jarrick; Yvonne Hirdman; Åsa Bergenheim; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Masculinity; masculinities; gender; power; middle class; passions; character; self-made man; sexuality; prostitution; homosocial; the male norm; George L. Mosse; advice manuals; autobiographies; alcohol; gambling; History; Historia; History; historia;

    Sammanfattning : This is a study of continuity and change in middle-class conceptions of ideal manhood. My theoretical cues are the notions of the male as an unproblematised and genderless norm, masculinity as homosocial, and George L. Mosse’s use of countertypes. Notions of passions, youth, and character were important throughout the century. LÄS MER

  3. 32. Vattenfysikalisk-kemiska och bottenfaunaförhållanden i ett norrländskt vattendrag påverkat av utsläpp från sulfidmalmbrytning och anrikning

    Författare :Bertil Brånin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mining; metals; pollution; stream; physicochemical; invertebrates and diversity index;

    Sammanfattning : Gruvbrytnings- och anrikningsverksamheten av komplexa zink-och kopparsulfidmalmer orsakar på flera håll i Västerbottens län vattenföroreningsproblem. För att studera effekterna av utsläppen i recipienten, har undersökningar och utvärderingar gjorts av de fysikalisk-kemiska och biologiska förhållandena i Vormbäcken 1971 - 1975. LÄS MER

  4. 33. Small-scale pattern and mobility of plant species in Alvar grassland

    Författare :Xiaobing Dai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; association analysis; cattle dung; decomposition; limestone grassland; Gland; PASFRAN; soil seed bank type; Sweden; turn-around time; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Studies of the small-scale pattern, mobility of plant species and the effects of cattle dung deposition and decomposition on the soil seed banks and the above-ground vegetation were carried out in an alvar limestone grassland in Gettlinge, on the Baltic island of Öland, Sweden.A new method for pattern detection using transect data Patch Size Frequency Analysis (PASFRAN), was developed.

  5. 34. The effect of simulated anthropogenic nitrogen deposition on the net carbon balance of boreal soils

    Författare :Nadia Maaroufi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Anthropogenic activities have globally increased nitrogen (N) deposition and carbon dioxide (CO₂) gas emissions. It is proposed that anthropogenic N deposition may increase the size of boreal forest CO₂ sink, because boreal ecosystems are N limited. LÄS MER

  7. 35. Herbivory and plant community structure in a subarctic altitudinal gradient

    Författare :Jon Moen; Nancy Huntly; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; arctic and alpine vegetation; competition; exclosures; lemmings; plant defences; plant-plant interactions; Ranunculus glacialis; snow-bed; structuring factors; tall herb meadow; vertebrate grazing; voles;

    Sammanfattning : The object of this thesis was to study plant community structure, especially in relation to vertebrate herbivory, in an altitudinal gradient in the Fennoscandian mountain chain.A sowing experiment in a high alpine Ranunculus glacialis population showed that seeds germinated better in cleared microsites than under established individuals.
