  1. 31. Molecular control of activity - dormancy transitions in Populus

    Författare :Madeleine Englund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Perennials such as woody plants, growing in the high northern part of the earth have to cope with seasonal changes alternating between mild summer and the harsh winter periods. To survive and adapt their reproductive phase to the most favorable environmental conditions trees cycle between periods of active growth during summer and a state of growth arrest during winter, referred to as the activity- dormancy cycle.

  3. 32. NMR studies on calcium-induced conformational transitions in calmodulin

    Författare :Johan Evenäs; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; NMR; conformational exchange; calmodulin; calcium binding; Fysikalisk kemi;

    Sammanfattning : Nuclear magnetic resonance (NMR) spectroscopy was used in order to investigate the relationships between structure, dynamics and calcium binding in the intracellular regulatory protein, calmodulin. Calmodulin consists of two similar domains, each binding two calcium ions with positive cooperativity. LÄS MER

  4. 33. Crystallization of the superconducting phase in unconventional superconductors

    Författare :Patric Holmvall; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pattern formation; spontaneous symmetry breaking; Andreev bound states; mesoscopic superconductivity; phase crystals; thin superconducting films; phase transitions; non-local Ginzburg-Landau theory; time-reversal symmetry; flat bands; unconventional superconductivity; quasiclassical theory; translational symmetry; cuprates; inhomogeneous superconductivity;

    Sammanfattning : Superconductivity is a macroscopic quantum phenomenon, in the sense that a macroscopic number of electrons form a pair condensate, that occupies a single ground state. The electrons in this state are phase-coherent, breaking global U (1)-symmetry, and spatial variations of the phase imply superflows that usually cost kinetic energy, resulting in a uniform and rigid phase.

  5. 34. Safe Transitions to Manual Driving From Faulty Automated Driving System

    Författare :Josef Nilsson; RISE; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver takeover; functional safety; automated driving; safety; vehicle automation; driver capability; brake failure; controllability; driving simulator.;

    Sammanfattning : This thesis presents a method to assess the safety of transitions from automated to manual driving when vehicle automation fails. The method is based on contributions to the understanding of human driving behavior, also presented in this thesis. LÄS MER

  7. 35. Structure studies of some ternary copper chalcogenides

    Författare :Lasse Norén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Ternary copper chalcogenides; Structures; Phase transitions; Disorder; Transformations; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Copper has in its heavier chalcogenides often a high mobility in the solid state. This behaviour has also be found for some ternary compounds where copper appears to govern the observed phase transitions and structural transformations. LÄS MER
