  2. 1. Flow Over Large-Scale Naturally Rough Surfaces

    Author : Robin Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The fluid mechanical field of rough surface flows has been developed ever since the first experiments by Haagen (1854) and Darcy (1857). Although old, the area still holds merit and a surprising amount of information have to this day yet to be fully understood, which surely is a proof of its complexity. READ MORE

  4. 2. Virus Dynamics in Naturally Varroa-Resistant Honeybee Populations

    Author : Srinivas Thaduri; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The ectoparasitic mite, Varroa destructor, together with its associated viruses is the most significant threat to honeybee (Apis mellifera) health world-wide. Since the introduction of varroa to the new host species, the European honey bee (Apis mellifera), it has been responsible for the near complete eradication of wild and feral honeybee populations in Europe and North America.

  5. 3. Sorption and weathering properties of naturally occurring chlorites

    Author : Åsa Gustafsson; KTH; []
    Keywords : chlorite; nickel; sorption; surface complexation; dissolution rate.;

    Abstract : Chlorite is a ferrous silicate mineral occurring as afracture filling mineral in the Swedish granite bedrock thatsurrounds the area of the candidate Swedish geologicalrepositories for nuclear waste. To investigate the importance of chlorites as a naturalbarrier for radionuclide migration sorption of Ni(II) onto anatural chlorite was chosen as the studied system. READ MORE

  6. 4. Quantum computing with naturally trapped sub-nanometre-spaced ions

    Author : Lars Rippe; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laserteknik; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; akustik; optik; Elektromagnetism; optics; acoustics; Electromagnetism; Fysik; Physics; entanglement; spectroscopy; rare-earth-metal-ion-doped crystals spectral hole-burning; inversion; excitation; laser stabilization; quantum computation; quantum gate;

    Abstract : The main aim of this work, was to lay the foundations for the experimental realisation of a quantum mechanical controlled NOT gate in rare-earth-metal-ion-doped crystals. Small amounts of rare-earth elements, added during the growth of some inorganic crystals, will become substituted into the crystal lattice as trivalent ions. READ MORE

  7. 5. The photophysics and functions of some naturally occurring carotenoids

    Author : Helena Billsten; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; xanthophyll-binding proteins; vibrational relaxation; light-harvesting complexes; carotenoid aggregates; carotenoids; excited states; femtosecond pump-probe spectroscopy; xanthophylls;

    Abstract : Carotenoids are one of the most widespread and important group of pigments in Nature and they can act as light-harvesting agents, photoprotectors and antioxidants. Mechanisms of their multiple functions are not fully understood mainly because their complicated photophysics involving ?dark? excited states. READ MORE
