  1. 11. The Impact of Multiple Drivers on Marine Systems : Novel approaches for studying structural changes

    Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. LÄS MER

  3. 12. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Författare :Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Sammanfattning : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. LÄS MER

  4. 13. Electronic and structural properties of nanoclusters

    Författare :Alexey Tal; Igor Abrikosov; Peter Münger; Weine Olovsson; Alessandro De Vita; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nanoclusters have gained a huge interest due to their unique properties. They represent an intermediate state between an atom and a solid, which manifests itself in their atomic configurations and electronic structure. LÄS MER

  5. 14. Deciphering Carbohydrate Structure : From NMR Chemical Shifts to Conformational Analysis

    Författare :Kevin M. Dorst; Göran Widmalm; Martina Delbianco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR chemical shift prediction; Structural elucidation; Conformational studies; NMR spectroscopy; MD simulations; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are ubiquitous in nature and exhibit a multitude of roles. Besides nucleic and amino acids, they can be regarded as the third alphabet of life. They are used as energy source to fuel the cells, as structural building blocks and play a key role in cellular recognition processes. LÄS MER

  7. 15. Structural-functional studies of mitochondrial matrix proteins

    Författare :Saba Shahzad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mitochondria;

    Sammanfattning : The mitochondrion is the powerhouse of the eukaryotic cell. Most of the energy required to carry out cellular processes is generated inside mitochondria via the process of oxidative phosphorylation. The machinery required for oxidative phosphorylation is encoded by both the nuclear and the mitochondrial genome. LÄS MER
