  2. 11. Derivation, Characterization and Differentiation of Feeder-Free Human Embryonic Stem Cells

    Author : Narmin Bigdeli; Göteborgs universitet; []
    Keywords : Embryonic Stem Cells; Differentiation;

    Abstract : Human embryonic stem cells (hESCs) are pluripotent cells with self-renewal ability, derived from the inner cell mass of a human blastocyst. They have the remarkable potential to develop into different cell types and can thus be used to regenerate and restore damaged tissues and organs in the entire body. READ MORE

  4. 12. Prior-less derivation of the astrophysical factor of Dwarf Spheroidal galaxies

    Author : andrea chiappo; jan dr. conrad; garrelt mellema; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dwarf galaxies; dark matter; fysik; Physics;

    Abstract : Dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are considered ideal targets for particle Dark Matter (DM) identification. Indirect detection strategies entail examining dSphs in search for signals of annihilating or decaying DM, in the form of excess electrons or gamma- and X-ray photons above the astrophysical background.

  5. 13. Optimisation of human embryonic stem cell derivation and culture : towards clinical quality

    Author : Susanne Ström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : hESC;

    Abstract : For clinical grade human embryonic stem cell (hESC) lines, a robust derivation and culture system without any substances having animal origin would be optimal. The general aims of these studies have been to gradually improve our hESC derivation and cultures. READ MORE

  6. 14. Structure-driven derivation of inter-lingual functor-argument trees for multi-lingual generation

    Author : Stefan Svenberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We show how an inter-lingual representation o messages can be exploited for natural language generation of technical documentation into Swedish and English in a system called Genie. Genie has a conceptual knowledge base of the facts considered as true in the domain. A user queries the knowledge base for the facts she wants the document to include. READ MORE

  7. 15. Phases in the NaNbO₃-Nb₂O₅-WO₃ system : derivation of complex structures by twinning, fourling and anti-phase-boundary operations on the ReO₃-type structure

    Author : Bengt-Olof Marinder; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The compounds of the title system are reviewed with emphasis on their crystal structures. The principles used in describing them include not only the well-known concept of crystallographic shear in ReOg and the concomitant notion of block structures but also new applications of the idea of chemical twinning of an ReO^-type structure on the unit cell level.
