    Sammanfattning : The purpose of this thesis was to examine the role of growth factors and the urokinase plasminogen activator (uPA) system in human endometrial angiogenesis. Growth factors as well as progesterone increased expression of the main inhibitor of uPA (PAI-1) in primary cultures of endometrial stromal cells. LÄS MER

  3. 2. On gene regulatory networks and data fitting

    Sammanfattning : Living organisms can be viewed as complex biological machines. In order to function, they must regulate their internal mechanism to do the right thing, at the right time, and in the right amount. Part of this regulation is encoded in gene regulatory networks. LÄS MER

  4. 3. Ecological interactions in human modified landscapes : Landscape dependent remedies for the maintenance of biodiversity and ecosystem services

    Författare :Arvid Bolin; Biodiversitet; []
    Nyckelord :Central place foraging; Agriculture; Competition; Ecosystem service; Species coexistence; bumble bees; landscape ecology; Biodiversity; Agri-environment scheme; Central place foraging; jordbruk; konkurrens; landskaps ekologi; humlor; bin;

    Sammanfattning : Modern agricultural practices have led to an intensification of the agricultural landscape which has negatively affected both biodiversity and the ecosystem services it provides. In my thesis I have used ecological theory of optimal foraging to try and explain how landscape structure, landscape composition and agricultural management can explain the loss of biodiversity and how remedies can efficiently be implemented.

  5. 4. Patterns of Care : Relating Altruism in Sociobiology and the Christian Tradition of Agape

    Författare :Eva-Lotta Grantén; Centrum för teologi och religionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; kunskapsteori; metafysik; estetik; Praktisk filosofi; ideology; epistemology; Sociobiology; Agape; Altruism; Science and Religion; Independence; Conflict; Integration; Care; Systematic philosophy; ethics; metaphysics; aesthetics; ideologi; General; systematic and practical Christian theology; Kristen teologi allmän; systematisk och praktisk ;

    Sammanfattning : The purpose of this study is to relate sociobiological theories of altruism to theories within the Christian tradition of agape. Firstly, it discusses the relation between scientific, ethical and theological understandings of altruism, and argues that it is possible to compare discussions of benevolent acts towards others or other-directedness.
