  1. 6. Little strokes fell great oaks : small RNA in potato and Phytophthora infestans interactions

    Författare :Kristian Persson Hodén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Small RNAs (sRNAs) are non-coding RNAs of approximately 20-30 nucleotides in length. sRNAs bind to Argonaute proteins (AGOs) an integrated partner of the RISC complex. sRNAs act as templates for RISC to recognize complementary mRNA transcripts which can be cleaved by AGOs and thereby cause gene inactivity.

  3. 7. Modelling and Intelligent Climate Control of Buildings

    Författare :Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Chalmers University of technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; indoor climate control; operative temperature; demand controlled ventilation; prediction; feed-forward control;

    Sammanfattning : The main purpose of the work presented in this thesis is to examine the possibilities of different control techniques together with intelligent building technology to improve the indoor climate and/or the energy efficiency of buildings. In particular, the possibilities of measuring more variables and using them as input to the controllers are examined. LÄS MER

  4. 8. High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

    Författare :Björn Nilsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tagged photons; photonuclear reactions; liquid helium; neutron detectors; liquid scintillators; giant resonances; angular distributions; differential cross sections; total cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2003:Nilsson;

    Sammanfattning : A comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintillator arrays.

  5. 9. Roles of the transient receptor potential channels and the intracellular Ca2+ channels in Ca2+ signaling in the beta-cells

    Författare :Amanda Jabin Fågelskiöld; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ca2 signaling;

    Sammanfattning : Previous studies from our group reported that pancreatic β-cells express ryanodine receptors (RyRs) that can mediate Ca2+-induced Ca2+ release (CICR). The full consequences of the activation of RyRs on Ca2+ signaling in these cells, however, remained unclear. LÄS MER

  7. 10. Drug resistance in acute myeloid leukemia : clinical and experimental studies

    Författare :Bertil Uggla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The long-term result of chemotherapy in acute myeloid leukemia (AML) is poor, even though a majority of AML patients initially respond to chemotherapy and achieve complete remission (CR). Initially resistant disease as well as relapse is a result of resistance to chemotherapy drug resistance. LÄS MER
