  1. 1. Biomass gasification in ABFB : Tar mitigation

    Author : Nemanova Vera; Klas Engvall; Joan Salvadó; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Ash; biomass; char; gasification; iron-based; petcoke; tar; Chemical Engineering; Kemiteknik;

    Abstract : Biomass gasification may be an attractive alternative for meeting future energy demand. Although gasification is a mature technology, it has yet to be fully commercialised due to tar formation. This study focuses on the tar mitigation in gas produced in an atmospheric bubbling fluidised bed (ABFB) gasification system. READ MORE

  2. 2. Climate change mitigation in China

    Author : Bo Xu; Ronald Wennersten; Kerstin Kuchta; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China; Climate change mitigation; Environmental Kuznets Curve EKC hypothesis; Mitigation target; Business-as-usual BAU scenarios; Policy instruments;

    Abstract : China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. READ MORE

  3. 3. Plastic Shrinkage Cracking In Concrete : Mitigation and Modelling

    Author : Faez Sayahi; Mats Emborg; Andrzej Cwirzen; Hans Hedlund; Pietro Lura; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

  4. 4. Nonlinearity mitigation in phase-sensitively amplified optical transmission links

    Author : Kovendhan Vijayan; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; copier-PSA; nonlinearity mitigation; phase-sensitive amplifier; self-phase modulation mitigation; low-noise amplification; optical transmission; crossphase modulation mitigation;

    Abstract : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. READ MORE

  5. 5. On the governmentalization of sustainability : the case of flood risk mitigation in Sweden

    Author : Per Becker; Roine Johansson; Jörgen Sparf; Karin Ingold; Mittuniversitetet; []
