  2. 6. Continuum Mechanics Modelling of Corrugated Board

    Author : Ulf Nyman; Institutionen för byggvetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; assumed natural strain shell; failure criterion; lifetime; reliability; moisture transport; sorption hysteresis; corrugated board; hygro-elasticity; Materiallära; materialteknik;

    Abstract : The storage of compressive loaded boxes in an environment with naturally varying humidity is a practical issue in corrugated board employment. Time dependent variables such as moisture content, strain fields, stress fields and material strength play important roles for the time to failure. READ MORE

    Author : Joakim Romson; Åsa Emmer; Peter Dinér; Lukas Käll; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MALDI; Concentration plates; Alkyl ketene dimer; CE-MALDI-MS2; On-target digestion; Automation; Robot; Pieris napi; spermatophore; ESI-MS2; Osteopontin; MALDI; Koncentrationsprovplatta; alkylketenedimer; CE-MALDI-MS2; enzymklyvning på provplatta; Automatisering; Robot; Pieris napi; Spermatofor; ESI-MS2; Osteopontin; Kemi; Chemistry;

    Abstract : Protein analysis is important to understanding biological systems, but sample diversity necessitates a multitude of analysis techniques and methods. Challenges that are addressed include analysis of low abundance samples, fractionation to reduce sample complexity, and automation to reduce time and cost. READ MORE

  5. 8. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

    Author : Eva Frühwald; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

    Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

  6. 9. In-plane mechanical properties of acetylated birch plywood and its response to humidity elevation

    Author : Yue Wang; Magnus Wålinder; Roberto Crocetti; Marie Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; wood modification; acetylation; in-plane mechanical properties; load-to-face grain angle; moisture effect; Björkplywood; trämodifiering; acetylering; mekaniska egenskaper i planet; belastningsriktning; klimategenskaper; Building Materials; Byggnadsmaterial;

    Abstract : Due to the recent flourish of modern timber structures, there is an increasing demand for engineered wood products (EWPs). However, outdoor exposure of EWPs often poses a risk of durability-related issues. READ MORE

  7. 10. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

    Author : Evelina Brännvall; Britt-Marie Steenari; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. READ MORE
