  1. 11. Sliding stability re-assessment of concrete dams with bonded concrete-rock interfaces

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Alexandra Krounis; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; sliding stability; cohesion; shear strength; uncertainty; bond; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded.In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded.

  2. 12. Shear in Concrete Structural Elements Subjected to Dynamic Loads

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Johan Magnusson; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; initial response; shear failure; shear capacity; numerical simulations; bond; shear span; support reactions; Dynamisk last; initial respons; skjuvbrott; skjuvkapacitet; numeriska simuleringar; förankring; skjuvspännvidd; upplagsreaktioner; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. LÄS MER

  4. 14. Probing unoccupied electronic states in aqueous solutions

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Lars-Åke Näslund; Stockholms universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray absorption; x-ray absorption spectroscopy; XAS; NEXAFS; water; liquid water; aqueous solution; hydrogen bond; hydrogen bond network; local geometry; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Water is one of the most common compounds on earth and is essential for all biological activities. Water has, however, been a mystery for many years due to the large number of unusual chemical and physical properties, e.g. decreased volume during melting and maximum density at 4 °C. LÄS MER

  5. 15. Enzyme assays for lignin–carbohydrate bond hydrolysis

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Hampus Sunner; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enzyme kinetic param- eter estimation; Glucuronoyl esterase; Enzyme assays; Lignin-carbohydrate bonds; Synergistic enzyme assay;

    Sammanfattning : To identify, produce, and use enzymes, analytical methods known as enzyme assays are employed. Enzyme assays are based on analysing the changes brought about on a substrate by an enzyme under defined conditions. Assays are often based on simplified reactions acting as substitutes for the reaction of interest. LÄS MER
