  1. 21. Internal frost damage in concrete - experimental studies of destruction mechanisms

    Författare :Katja Fridh; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tining; frysning; kallt klimat; frostskador skador; betong; materiallära; materialteknik; frost; ice formation; material technology; calorimetry; concrete; length change; upptining; fukt; beständighet; livslängd; forskning;

    Sammanfattning : The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.

  4. 23. Reactions with radioactive beams and development of scintillator-based detector systems

    Författare :Alexander Knyazev; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Reactions; Detectors; SImulation; Light transport simulation; Calorimetry; Fysicumarkivet A:2020:Knyazev;

    Sammanfattning : An experiment on elastic scattering of 15 C on 208 Pb at an energy of 65 MeVwas performed at ISOLDE (CERN) exploiting the advantages of the ISOL te-chinique. The measurement showed in increase of the reaction cross section to3035 mb with respect to 12 C, confirming the results obtained at 80 MeV/u. LÄS MER

  5. 24. Diastereomeric Effects in DNA Binding – Biological and Biophysical Studies on Ruthenium Complexes

    Författare :Anna Mårtensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neighbor interaction; spectroscopy; diastereomeric; kinetics; antimicrobial activity; ruthenium; calorimetry; intercalation; DNA; enantiomer;

    Sammanfattning : Organic molecules, such as glucose and amino acids, are most often chiral. This means that their mirror-images are different, in the same way a left and a right hand are different from each other. For example, the DNA double helix in its standard form twists like a right-handed screw. LÄS MER

  7. 25. Thermodynamics of Peptide Nucleic Acid Interactions with DNA

    Författare :Tommi Ratilainen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; enthalpy-entropy compensation; ionic strength; nucleic acids; fluorescence energy transfer; PNA; calorimetry; sequence-specific binding;

    Sammanfattning : Peptide Nucleic Acid (PNA) is a DNA mimic with the natural nucleobases attached to a charge-neutral pseudopeptide backbone. It has remarkably strong and sequence-specific binding affinity to natural nucleic acids (DNA and RNA), mainly attributed to the lack of charge in the PNA backbone. LÄS MER
