  1. 1. Development and Application of Non-linear Mid-infrared Laser Spectroscopy for Combustion Diagnostics

    Author : Zhiwei Sun; Lund University.; Lunds universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Degenerate four-wave mixing; Polarization spectroscopy; Mid-infrared; Non-linear laser spectroscopy; Laser diagnostics; Combustion; Flame; HITRAN; Concentration; Temperature; Fysicumarkivet A:2012:Sun;

    Abstract : The work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking accessible electronic (one-photon) transitions in the ultraviolet (UV) or visible spectral region.

  3. 3. Mechanochemical Modeling of Smooth Muscle Activation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sae-Il Murtada; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomechanics; Muscle contraction; Smooth muscle; Contractile unit; Filament overlap; Intracellular calcium; Carotid artery; Mathematical model;

    Abstract : Smooth muscle has an important role in several physiological processes, where it regulates the wall tension and the size of hollow organs. In blood vessels, the contraction and relaxation of smooth muscle contribute to the mechanical stability of the vessel wall and determines the diameter. READ MORE

  4. 4. Structural Changes in Nonionic Surfactant Systems

    University dissertation from Lund University (Media-Tryck)

    Author : Sanja Bulut; Lund University.; Lunds universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vesicles; Nonionic Surfactant; Wormlike Micelles; Lamellar Phase; NMR; MRI; SLS; DLS; cryo-fracture-TEM; centrifugation; cryo-TEM;

    Abstract : In this thesis we have studied structural changes of a nonionic surfactant self-assembly, as governed by changes in temperature and concentration. The techniques used in experimental investigations were dynamic and static light scattering, nuclear magnetic resonance and cryo-transmission electron microscopy (using a novel specimen preparation protocol).

  5. 5. Numerical stress analysis in hybrid adhesive joint with non-linear materials

    University dissertation from Luleå : Luleå University of Technology

    Author : Nawres Al-Ramahi; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : This thesis presents systematic numerical study of stresses in the adhesive of a single-lap joint subjected to various loading scenarios (mechanical and thermal loading). The main objective of this work is to improve understanding of the main material and geometrical parameters determining performance of adhesive joint for the future analysis of failure initiation and development in these structures.
