  1. 1. Simulations of Simple Fluids and Surface Forces

    University dissertation from Department of Chemistry, Lund University

    Author : Martin Trulsson; Lund University.; Lunds universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular modeling; Surface Forces; Dielectric Constant; Charge Capacitance; Charge Regulation; Hypersphere; Statistical mechanics; Intermolecular interactions; Col- loidal Stability; Simulations; Fluids;

    Abstract : A considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. READ MORE

  2. 2. Theoretical Studies of Simple Polar Fluids

    University dissertation from Department of Chemistry, Lund University

    Author : Joakim Stenhammar; Lund University.; Lunds universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polar fluids; Dielectric theory; van der Waals forces; Molecular simulation;

    Abstract : Fluids composed of dipolar molecules are ubiquitous in nature, with water being the most prominent example. Due to their great importance and large complexity, a basic scientific understanding of the structure and thermodynamics of polar fluids is essential. READ MORE

  3. 3. Water-based hydraulic fluids : rheology and elastohydrodynamic lubrication

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ove Isaksson; Luleå tekniska universitet.; [1986]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Maskinelement; Machine Elements;

    Abstract : Experiments have been carried out to measure traction, antiwear and rheological properties of water-based hydraulic fluids. Four types of fluids have been examined, emulsions, micro-emulsions, synthetic solutions and water-glycols. READ MORE

  4. 4. Rheological properties of lubricating fluids

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan Lundberg; [1987]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Obliteration (gobbing) caused by water based lubricating fluids is studied experimentally by analyzing the flow through a small channel. Flow measurements, energy dispersive X-ray microscopy and photos show, that the rate of gobbing depends on which type of fluid that is being used. READ MORE

  5. 5. Cytokines and their soluble receptors in nasal fluids from school children with allergic rhinitis

    University dissertation from Göteborg

    Author : Mikael Benson; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allergic rhinitis; school children; cytokines; soluble cytokine receptors; nasal fluids;

    Abstract : Allergic inflammation is associated with a shift in the balance between cytokines produced by two T helper subsets (Th1 and Th2) towards a preponderance of Th2 cells. Interleukin (IL)-4 is produced by Th2 cells and interferon-g (IFN-g) by Th1 cells. The ratio IL-4/IFN-g is often used as a marker of the balance between the cytokines. READ MORE
