  2. 16. Experimental Determination of Aeracoustic Sources in Low Mach Number Internal Flows

    Author : Andreas Holmberg; Hans Bodén; Lars Enghardt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeracoustics; ducts; N-ports; scattering matrix; wave decomposition; source determination; over-determination; flow noise; fluid-acoustic interaction; fluid-structure-acoustic interaction; wave number; T-junction; power balance; grazing-bias flow; Acoustics; Akustik; Vehicle engineering; Farkostteknik;

    Abstract : In this thesis, the in-duct experimental methods for determining aeroacoustic N-ports of in-duct elements are discussed and improved. The scattering matrix determination methods and the related wave decomposition methods are evaluated from measurements in an empty duct carrying a mean flow. READ MORE

  4. 17. Deciphering Carbohydrate Structure : From NMR Chemical Shifts to Conformational Analysis

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

    Abstract : 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. READ MORE

  5. 18. On protein structure, function and modularity from an evolutionary perspective

    Abstract : We are compounded entities, given life by a complex molecular machinery. When studying these molecules we have to make sense of a diverse set of dynamical nanostructures with wast and intricate patterns of interactions. READ MORE

  6. 19. Structure determination of Methanocaldococcus jannaschii nucleoside kinase

    Author : Linda Arnfors; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Methanocaldococcus jannaschii; Archaea; hyperthermophile; nucleoside kinase; ribokinase family; X-ray crystallography; differential scanning calorimetry; thermal stability;

    Abstract : All organisms can be divided into the tree kingdoms of life: Archaea, Bacteria and Eukarya. Archaeal organisms are often found to exhibit, compared to human perspectives, extreme environments, such as high temperature, high salt and acidic habitats. Many archaeal species are hyperthermophiles, i.e. READ MORE
