  1. 1. Novel Regulators of the TGF-β Signaling Pathway

    Författare :Marcin Kowanetz; Aristidis Moustakas; Carl-Henrik Heldin; Caroline Hill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; TGF-β; Smad; Id; EMT; cell cycle; SNF1LK; ubiquitin; degradation; signal transduction; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The transforming growth factor-β (TGF-β) superfamily consists of related multifunctional cytokines, which include TGF-βs, activins, and bone morphogenetic proteins (BMPs) and coordinate several biological responses in diverse cell types. The biological activity of TGF-β members is executed by transmembrane serine/threonine kinase receptors and intracellular Smad proteins. LÄS MER

  3. 2. Allocation of body resources to reproduction in butterflies

    Författare :Fredrik Stjernholm; Bengt Karlsson; Christer Wiklund; Jane K. Hill; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Zoology; Ecology; Butterflies; Reproduction; Life histories; Trade-offs; Resource use; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The life-history of an organism can be studied and understood in terms of acquisition and expenditure of resources. In butterflies, the use of resources for reproduction has been the focus of much research due to the possibility to easily quantify both the input of resources from different sources over the life-cycle as well as the partitioning of these resources to reproduction.

  4. 3. Gubben på kullen : Om den smärtsamma skillnaden mellan politiska intentioner och praktiska resultat

    Författare :Mikael Glemdal; Benny Hjern; Göran Bostedt; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; Statsvetenskap;

    Sammanfattning : Many social problems have proved unexpectedly difficult to solve. To analysethe unintended social repercussions of intentional human actions is considered to be the most important task of the social sciences. The ’unintended’ stand inthe way of satisfaction for human needs. LÄS MER

  5. 4. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold

    Författare :Robert Eriksson; KTH; []
    Nyckelord :up-hitt teeming; model powder; inclusions; plant trials; thermal diffusivity; fluid flow; physical modeling;

    Sammanfattning : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. LÄS MER

  7. 5. Sulphide-rich tailings remediated by soil cover : evaluation of cover efficiency and tailings geochemistry, Kristineberg, northern Sweden

    Författare :Erik Carlsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The efficiency of soil cover as a method of remediation of sulphide-rich tailings has been studied at an impoundment at the Kristineberg mine, Northern Sweden. Two variations of soil cover were used in the remediation. The major part of the impoundment was covered with a 1.0 m layer of till where the groundwater table was shallow. LÄS MER
