  2. 1. Oases of Air : A Phenomenological Study of John Banville's Science Tetralogy

    Author : Joakim Wrethed; H.W. Fawkner; David Pierce; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; John Banville; science tetralogy; contemporary Irish fiction; aseity; air; substance; phenomenology; intentionality; constitution; epistemology; Literature; Litteraturvetenskap;

    Abstract : This phenomenological study of John Banville’s fiction exhibits the way in which Doctor Copernicus, Kepler, The Newton Letter, and Mefisto persistently present air as a constituting factor. Air occurs as a phenomenological oasis permitting constitution to effectuate disclosure ex nihilo. READ MORE

  4. 2. Surface interactions and adsorbate structures : An atomic force microscopy study

    Author : Goran Bogdanovic; KTH; []
    Keywords : atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

    Abstract : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

  5. 3. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Abstract : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. READ MORE

  6. 4. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

    Abstract : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

  7. 5. Surface Force and Friction : effects of adsorbed layers and surface topography

    Author : Xiaoyan Liu; Per Claesson; Bjorn Torger Stokke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

    Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE
