  2. 26. Theoretical Studies on Kinetics of Molecular Excited States

    Author : Feng Zhang; Yi Luo; Theodore S. Dibble; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

    Abstract : HTML clipboardKinetics on molecular excited states is a challenging subject in the field of theoretical chemistry. This thesis pays attention to theoretical studies on kinetics of photo-induced processes, including photo-chemical reactions, radiative and non-radiative transitions (intersystem crossing and internal conversion) in molecular and bio-related systems.

  4. 27. Ozone chemistry in aqueous solution : ozone decomposition and stabilisation

    Author : Margareta Eriksson; Lars Kloo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. READ MORE

  5. 28. Time-Based Reconstruction of Hyperons at PANDA at FAIR

    Author : Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Sophie Grape; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; hyperons; track reconstruction; online; cellular automaton; 4D tracking; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at the future FAIR (Facility for Anti-proton and Ion Research) offers unique possibilities for performing hyperon physics.The almost full 4π coverage of the detector will enable the reconstruction of both hyperon and antihyperon which will be created together in proton-antiproton collisions.

  6. 29. Succession of wood-inhabiting fungal communities : diversity and species interactions during the decomposition of Norway spruce

    Author : Elisabet Ottosson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Dead wood constitutes an important substrate for biodiversity in boreal forests. As the wood decays, fungal communities develop and species associations are formed. Species interactions are thought to affect community development, but the mycelial dynamics within fungal communities are poorly understood. READ MORE

  7. 30. Partial Discharge Analysis at Arbitrary Voltage Waveform Stimulus

    Author : Xiaolei Wang; Hans Edin; Elisabeth Lindell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Partial discharge (PD) detection is widely used to diagnose the defects and degradation in an electrical insulation system. Generally, PD are measured with 50 Hz AC sinusoidal voltage in the on-line situation, but can also be detected at other voltage stimulus in some off-line situations. READ MORE
