  1. 1. Regulation of cellular Hsp70 : Proteostasis and aggregate management

    Author : Jayasankar Mohanakrishnan Kaimal; Claes Andréasson; Pierre Goloubinoff; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Proteins have to be folded to their native structures to be functionally expressed. Misfolded proteins are proteotoxic and negatively impact on cellular fitness. To maintain the proteome functional proteins are under the constant surveillance of dedicated molecular chaperones that perform protein quality control (PQC). READ MORE

  2. 2. An investigation into some aspects for foamed bitumen technology

    Author : May Namutebi; Björn Birgisson; Alvaro Guarin; Umaru Bagampadde; Baoshan Huang; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foamed bitumen; Binder ageing; Aggregate coating; Compaction; Mix design; Aggregate porosity; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Despite applications of foamed bitumen technology in pavement construction in various places around the world, there are still several aspects about this technology that are not clear. In addition, knowledge on foamed bitumen technology is mainly empirical and lacks scientific basis. READ MORE

  3. 3. Performance model for unbound grnular materials pavements

    Author : Tatek Fekadu Yideti; Björn Birgisson; Andrew Dawson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; unbound granular materials; aggregate; packing theory; gradation; primary structure; secundary structure; permanent deformation; resilient modulus;

    Abstract : Recently, there has been growing interest on the behaviour of unbound granular material in road base layers. Researchers have studied that the design of a new pavement and prediction of service life need proper characterization of unbound granular materials, which is one of the requirements for a new mechanistic design method in flexible pavement.

  4. 4. Dry Classification of Fine Aggregates for Concrete and Asphalt

    Author : Robert Johansson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; asphalt; classification; aggregate;

    Abstract : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. READ MORE

  5. 5. Beyond Köhler theory : Molecular dynamics simulations as a tool for atmospheric science

    Author : Thomas Hede; Caroline Leck; Veli-Matti Kerminen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Köhler theory; molecular dynamics; surface tension; aggregate; climate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : In this thesis, the results from molecular dynamics (MD) simulations of nanoaerosol clusters are discussed. The connecting link of these studies is the Köhler theory, which is the theory of condensational growth and activation of cloud droplets to form clouds. READ MORE
