  1. 1. Investigation of vanadium-containing oxide systems : CALPHAD and experiments

    Författare :Yang Yang; Malin Selleby; Caisa Samuelsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calphad; thermodynamic modelling; compound energy formalism; evaporation kinetics; activation energy; TGA; activity;

    Sammanfattning : Fundamental studies on thermodynamic properties of vanadium-containing oxides systems are essential to understand practical vanadium metallurgical process. The CALPHAD technique is here applied to the thermodynamic modelling of the V-O, Ca-V-O and Ti-V-O systems. The compound energy formalism is used for all the solution phases. LÄS MER

  3. 2. Prognostic factors of electroconvulsive therapy for depression

    Författare :Ole Brus; Axel Nordenskjöld; Yang Cao; Jayanti Chotai; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electroconvulsive therapy; unipolar depression; bipolar depression; outcome; memory; relapse; remission; register-based cohort study;

    Sammanfattning : Depression is a severe disorder that can be difficult to treat. One approach to treating depression is electroconvulsive therapy (ECT), whereby electricity is administered through electrodes fastened to the patient’s head. This procedure is effective, however not all patients respond. LÄS MER

  4. 3. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

    Författare :Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.

  5. 4. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    Författare :Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. LÄS MER
