  2. 1. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

    Author : Magnus Andersson; Ove Axner; Lene Broeng Oddershede; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; Physics; Fysik;

    Abstract : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. READ MORE

  4. 2. Bodies of vital matter: Notions of life force and transcendence in traditional southern Italy

    Author : Per Binde; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; socialanropologi; Italien; magi; övertro; social anthropology; Italy; symbolism; cosmology; Roman Catholicism; social organization; vitality; folk medicine; burial practices; death; cult of saints; the evil eye; witches;

    Abstract : Bodies of Vital Matter presents an innovative study that explores folk beliefs relating to the vital force of the human body and to the transcendence of the corporal. The time frame is the period from the unification of Italy to the Second World War. There are three principal themes of investigation. READ MORE

  5. 3. Structural, Kinetic and Thermodynamic Aspects of the Crystal Polymorphism of Substituted Monocyclic Aromatic Compounds

    Author : Michael Svärd; Åke Rasmuson; Hugo Meekes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymorphism; crystallization; thermodynamics; kinetics; nucleation; crystallography; solubility; phase equilibria; polymorphic transformation; solution history; metastable zone; classical theory of nucleation; two-step theory of nucleation; cluster; crystal structure prediction; lattice energy; molecular mechanics; force field; electrostatic potential; potential energy hypersurface; m-aminobenzoic acid; m-hydroxybenzoic acid; Chemical engineering; Kemiteknik;

    Abstract : This work concerns the interrelationship between thermodynamic, kinetic and structural aspects of crystal polymorphism. It is both experimental and theoretical, and limited with respect to compounds to substituted monocyclic aromatics. READ MORE

  6. 4. Thermally Induced Fracture Performance of Asphalt Mixtures

    Author : Prabir Kumar Das; Björn Birgisson; Dallas Little; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low temperature cracking; asphalt concrete fracture mechanics; viscoelasticity; non-linear thermal contraction coefficient; atomic force microscopy; wax; wax crystallization; SRA - Transport; SRA - Transport;

    Abstract : A major distress mode in asphalt pavements is low temperature cracking, which results from the contraction and expansion of the asphalt pavement under extreme temperature changes. The potential for low temperature cracking is an interplay between the environment, the road structure and importantly the properties of the asphalt mixture. READ MORE

  7. 5. Analysis of entry phase in intermittent machining

    Author : Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Cutting forces and vibrations are essential parameters in the assessment of a cutting process. As the energy consumption in the machining process is directly affected by the magnitude of the cutting forces it is of vital importance to design cutting edges and select process conditions that will maintain high tool performance through reduced energy consumption.
