  1. 21. Evolution of the earliest molluscs

    Författare :Alexander P. Gubanov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

    Sammanfattning : The first helcionelloid molluscs appeared in the late Vendian and were forerunners ofthe sudden molluscan diversification of the Cambrian explosion. The diversification ofMollusca coincided with global changes in the lithosphere, hydrosphere, atmosphere,and biosphere coincident with the break-up of the Late Proterozoic supercontinentRodinia, a distinct shift in oceanic water geochemistry, and the sudden abundance ofshelled multicellular organisms.

  3. 22. Exploring the Molecular Dynamics of Proteins and Viruses

    Författare :Daniel Larsson; David van der Spoel; Modesto Orozco; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; virus dynamics; capsid dissolution; satellite tobacco necrosis virus; satellite tobacco mosaic virus; virus genome structure; gas phase protein structure; water layer; micelle embedded protein; membrane protein; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. LÄS MER

  4. 23. Postural control and adaptation to threats to balance stability

    Författare :Mitesh Patel; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural control; Visual; Vestibular; Somatosensory; Proprioception; Posturography; Complaint surface; Ageing; Mechanoreceptive sensation; Sleep deprivation; Adaptation; Muscle activity;

    Sammanfattning : Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory systems.

  5. 24. A study of war-affected children in Sri Lanka

    Författare :W.M.S.M. Kumari; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children; effects of war; rehbialition programmes;

    Sammanfattning : This licentiate thesis aims to build up an analytical model for studying rehabilitation programmes for children in Sri Lanka, with a view to future research. This area is considered very important, because children's perspectives in the post-war reconstruction efforts can be considered as still a largely invisible subject. LÄS MER

  7. 25. Adaptive tensor-based morphological filtering and analysis of 3D profile data

    Författare :Anders Landström; Cris Luengo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Image analysis methods for processing 3D profile data have been investigated and developed. These methods include; Image reconstruction by prioritized incremental normalized convolution, morphology-based crack detection for steel slabs, and adaptive morphology based on the local structure tensor.
