  2. 21. Borehole heat store design optimization

    Author : Bo Nordell; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. READ MORE

  4. 22. Conformational Studies of Biologically Active Peptides

    Author : Björn Walse; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PapD chaperone; P pili; desmopressin; DDAVP; protein-peptide interactions; glycopeptides; peptide design; transferred NOE; molecular dynamics simulations; circular dichroism; peptide conformation; NMR spectroscopy; immunogenic glycopeptides; Physical chemistry; Fysikalisk kemi;

    Abstract : In this work conformational studies have been performed on peptides from four different systems in an attempt to gain knowledge about their biological function. Circular dichroism (CD) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy in combination with distance geometry and restrained molecular dynamics simulations were the methods used.

  5. 23. Structural and Functional Studies of De Novo Designed Peptides at Surfaces

    Author : Patrik Nygren; Bo Liedberg; Thomas Ederth; Martin Malmsten; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofouling; vesicles; nanoparticles; peptide; peptide design; circular dichroism; Physical chemistry; Fysikalisk kemi;

    Abstract : The work presented in this thesis deals with the structural and functional properties of peptides at surfaces. The interaction of peptides with surfaces is an ever so common occurrence in our every day life, from the bug squashed on the windshield of our car to the barnacle on our boat, and from the blood plasma used in the hospital to the proteins in our cells.

  6. 24. Policy Framework for Material Resource Efficiency : Pathway Towards a Circular Economy

    Author : Leonidas Milios; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; resource efficiency; circular economy; policy studies; reuse; remanufacturing; recycling;

    Abstract : The strategic direction of the European Union (EU) over the past twenty years has focused on increasing resource productivity and innovation in the economy, aiming at the efficient use and secured supplies of resources, economic growth and job creation, with fewer environmental impacts. One of the basic premises of the new ‘Green Deal’ for Europe is the promotion of the circular economy. READ MORE

  7. 25. Analysis and Design of Conformal Array Antennas

    Author : Patrik Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conformal antennas; conformal arrays; UTD; high frequency method; MoM; hybrid method; mutual coupling; singly curved surface; doubly curved surface; geodesics; dielectric covered circular cylinder; non-paraxial region. paraxial region; waveguide fed; Electrical engineering; Elektroteknik;

    Abstract : Today there is a great need for communication between people and even between things, using systems onboard e.g. aircraft, cars, ships and satellites. As a consequence, these communications needs require antennas mounted on or integrated in the surfaces of different vehicles or platforms, i. READ MORE
