  4. 3. On the Nucleation and Inoculation of Metals

    Författare :Lena Magnusson; Hasse Fredriksson; Peter Schumacher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solidification; nucleation; inoculation; undercooling; interface energy; refractory metals; latent heat; inclusions; nodular cast iron; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Latent heat during recalesence and nucleation and post-recalesence temperature was analysed for refractory metals. An effect on latent heat was found by alloying the pure elements with other refractories. Latent heat was found to be 15-65% of tabulated values. Interface energy was evaluated from undercooling experiments. LÄS MER

  5. 4. Treåringar, kameror och förskola – en serie diffraktiva rörelser

    Författare :Lena O Magnusson; Claes Eriksson; Tarja Karlsson Häikiö; Hillevi Lenz Taguchi; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction; Innovative Learning; Innovativt lärande; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction;

    Sammanfattning : The aim of this thesis is to examine what happens when three-year-olds are given access to digital cameras, and what shape and form children’s photographic capacity takes within the framework of everyday pre-school activities. The notion that young children in pre-school rarely get to use cameras themselves, and that they take part in photographs produced by pre-school educators as part of an ongoing documenting practice rooted in the curriculum is the point of departure.

  7. 5. Fibroblast Growth Factor Receptor-1 Function in Vasculo- and Angiogenesis

    Författare :Peetra Magnusson; Lena Claesson-Welsh; Anne Eichmann; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; FGF; FGFR-1; VEGFR-2; PDGFR-β; endothelial cells; embryonic stem cell; angiogenesis; hematopoiesis; Patologi; Pathology; Patologi;

    Sammanfattning : During development of the mammalian embryo, spatial and temporal expression of fibroblast growth factors (FGFs) and their cognate receptors are vital in the regulation of a number of patterning processes. Inappropriate or decreased expression leads to severe malformations and even embryonic death. LÄS MER
