  1. 1. Pathophysiology and treatment of chlorine gas-induced lung injury : an experimental study in pigs

    Author : Jianpu Wang; Kai Knudsen; Östergötlands Läns Landsting; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : One of the most threatening scenarios in disaster medicine is the accidental release of toxic gases with the exposure of many people. In this respect, chlorine gas remains a significant threat due to its abundant use and transport through densely populated areas in modem society. READ MORE

  2. 2. Structure, Bonding and Transport of SiC and Graphitic Systems

    Author : Eleni Ziambaras; Chalmers University of Technology; []
    Keywords : nanostructures; Knudsen effect; Silicon Carbide SiC ; van der Waals interactions; density functional theory DFT .; graphite;

    Abstract : Today's development of new electronic devices requires materials that can operate under harsh conditions. One such material is Silicon Carbide (SiC) which exhibits superior properties such as chemical inertness, high durability, high thermal stability, high thermal conductivity, and extreme hardness.

  3. 3. Modelling of cathode-plasma interaction in short high-intensity electric arc : Application to Gas Tungsten Arc Welding

    Author : Alireza Javidi Shirvan; Isabelle Choquet; Håkan Nilsson; Armelle Vardelle; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric arc discharge; sheath; pre-sheath; Knudsen layer; doped refractory cathode; arc-cathode coupling; Gas Tungsten Arc simulation; OpenFOAM.; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. READ MORE

  5. 5. Acoustic separation of submicron particles in gaseous flows

    Author : Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Keywords : Acoustic; submicron particles; gaseous flows; separation; Teknisk mekanik; Engineering Mechanics;

    Abstract : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.
