  4. 2. Torque and Angle Controlled Tightening of Bolted Joints

    Author : Göran Toth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torque controlled tightening; deformation parameters; momentary elongation; deformation factor; torque; Bolted screwed joints; spring characteristic; Torx; torque and angle controlled tightening; hexalobular; final torque; snug torque; Taylor’s series expansions; preload; plastic deformation; permanent elongation; yield; friction diameter; plastic spring constant; clevis; turn-of-nut method; bearing surface pressure; twisting; Monte-Carlo simulations;

    Abstract : Reduced weight and fuel consumption, improved reliability and engine performance are the main requirements in the automotive industry of today. These requirements demand robust and optimized bolted joints, where a high amount of preload obtained by effective utilisation of the bolt is essential. READ MORE

  5. 3. Isomeric yield ratio measurements with JYFLTRAP : In quest of the angular momentum of the primary fragments

    Author : Vasileios Rakopoulos; Mattias Lantz; Stephan Pomp; Andreas Solders; José Benlliure; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products; scission; Penning trap.; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. READ MORE

  6. 4. Methane and Volatile Fatty Acids Production from Toxic Substrate

    Author : - Lukitawesa; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

    Abstract : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. READ MORE

  7. 5. Strength Criteria on Grouting Agents for Hard Rock- Laboratory studies performed on gelling liquid and cementitious grout

    Author : Magnus Axelsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory study; colloidal silica; rheology; shear strength; Grout; erosion; strength; cement; yield stress; silica sol;

    Abstract : Grouting is usually successful in excavations at moderate depths and groundwater inflow. At great depths, in post-grouting or in rock with a large inflow of water, grouting is more problematic due to the forces from groundwater. READ MORE
