  2. 1. Fluidized bed combustion - modeling and mixing

    Author : David Pallarès; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized bed combustion; Mixing; Modeling;

    Abstract : First demonstrated on industrial scale in 1976, fluidized bed combustion (FBC) rapidly became an established technology for solid fuel combustion with a currentinstalled capacity of about 30 GWe and power plants ranging from 10 to 460 MWe.The widespread use of the FBC technology both under so-called circulating and bubbling conditions (i.e. READ MORE

  4. 2. Capacitive Mixing for Extracting Concentration Gradient Energy

    Author : Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Abstract : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. READ MORE

  5. 3. Hygroscopic Growth of Atmospheric Aerosol Particles and Its Relation to Nucleation Scavenging in Clouds

    Author : Birgitta Svenningsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol formation; atmospheric aerosols; hygroscopic growth; nucleation scavenging; cloud; water activity; external mixing; tandem differential mobility analyser; Kärnfysik; cloud condensation nuclei spectra; Nuclear physics; TDMA; Fysicumarkivet A:1997:Svenningsson; inorganic salts;

    Abstract : Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. READ MORE

  6. 4. Biomaterials for Promoting Self-Healing of Bone Tissue

    Author : Sonya Piskounova; Jöns Hilborn; Tim Bowden; Simon Cool; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Osseointegration; implant coating; hyaluronan hydrogel; bone morphogenetic protein-2; hydroxyapatite; bone; delivery system; injectable; mixing; radioactive labeling; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. READ MORE

  7. 5. Ventilation Performance in Operating Rooms : A Numerical Assessment

    Author : Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

    Abstract : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. READ MORE
