  1. 1. Functional studies of two forkhead genes

    Författare :Mikael Heglind; Göteborgs universitet; []
    Nyckelord :forkhead genes; Foxs1; Foxi1; vacuolar type H -ATPase; boundary cap; neural crest stem cells;

    Sammanfattning : Forkhead genes are functionally diverse and several have been linked to human disease. A previous screen for forkhead genes identified the family member FOXS1. To characterize the function of this gene, we produced a mouse model in which the Foxs1 gene was replaced by a lacZ marker allele. LÄS MER

  3. 2. Monotonicity formulas and applications in free boundary problems

    Författare :Anders Edquist; Henrik Shahgholian; Wolfgang Reichel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Partial differential equations; PDE; Free boundary problems; Monotonicity formulas; Mathematical analysis; Analys;

    Sammanfattning : This thesis consists of three papers devoted to the study of monotonicity formulas and their applications in elliptic and parabolic free boundary problems. The first paper concerns an inhomogeneous parabolic problem. LÄS MER

  4. 3. Energy Transfer and Conversion in the Magnetosphere-Ionosphere System

    Författare :Lisa Rosenqvist; Stephan Buchert; Andris Vaivads; Mike Lockwood; Uppsala universitet; []
    Nyckelord :Space and plasma physics; solar system; space physics; magnetospheric physics; plasma physics; magnetic storms; substorms; boundary layers; magnetic reconnection; energy conversion; space weather; Rymd- och plasmafysik;

    Sammanfattning : Magnetized planets, such as Earth, are strongly influenced by the solar wind. The Sun is very dynamic, releasing varying amounts of energy, resulting in a fluctuating energy and momentum exchange between the solar wind and planetary magnetospheres. LÄS MER

  5. 4. Sensory neurons : stem cells and development

    Författare :Jens Hjerling-Leffler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sensory neuron; stem cells; development; boundary cap; GABA; TRPV 1; TRPA 1; TRPM8; calcium imaging; Foxs 1; SSEA-1; Schwann cells;

    Sammanfattning : The sensory nervous system is the only means we have of communicating with the surrounding world. The neurons responsible for the sensation of pain, touch, the ability to know the position of our limbs and part of maintenance of body posture are located in the dorsal root ganglia (DRG). LÄS MER

  7. 5. Caving mechanisms for a non-daylighting orebody

    Författare :Sraj Umar Banda; Jonny Sjöberg; Björn Nilsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel caving; numerical analysis; laser scanning; seismic data; large-scale structure; rock mass characterization; failure mechanism; discontinuum modeling; continuum modeling; caving analysis; voronoi modeling; bonded block model; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass. LÄS MER
