  1. 1. Enabling Surface Cleaning Robot for Large Food Silo

    Författare :Kinan Dandan; Amy Loutfi; Lars Karlsson; Mikael Ekström; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Confined space; surface cleaning robot; motion control; static and dynamic analysis;

    Sammanfattning : Working conditions in the dry cleaning and sanitation of confined interior spaces are often extreme, and workers need overall protection with tight clothing, helmets, face mask, earmuffs, and respirators. The environment is dirty, noisy with bad visibility and heavy with a high static work load. LÄS MER

  3. 2. Treatment of Wastewater Generated by Wood-based Dry Industries : Advances Oxidation Processes & Electrocoagulation

    Författare :Henrik Hansson; William Hogland; Marcia Marques; Ollie Dahl; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Advanced oxidation processes; Electrocoagulation; Fenton; Industrial storm-water; Ozone; Respirometry assays; Wastewater; Wood floor industry.; Environmental Chemistry; Miljökemi;

    Sammanfattning : Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp.

  4. 3. Laser cleaning as a conservation technique for corroded metal artifacts

    Författare :Yang Sook Koh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : Preservation of cultural property for the future is one of the most important activities of our society. The information which we can gather from such materials is a valuable key to understanding the past. Conservation is a process which includes a range of different treatments. LÄS MER

  5. 4. Prevention of Biofilm Formation on Silicone Rubber Materials for Outdoor High Voltage Insulators

    Författare :Sevil Atari Jabarzadeh; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage insulator; silicone rubber; biofouling; biofilm; biocide; superhydrophobicity; self-cleaning; hierarchical roughness;

    Sammanfattning : Microbial colonization on the surface of silicone rubber high voltage outdoor insulators often results in the formation of highly hydrated biofilm that influence the surface properties, such as surface hydrophobicity. The loss of hydrophobicity might lead to dry band formation, and, in the worst cases, flashover and failure of the insulator. LÄS MER

  7. 5. An Experimental Study on Micro-Hydrodynamics of Evaporating/Boiling Liquid Film

    Författare :Shengjie Gong; Ma Weimin; Horst-Michael Prasser; KTH; []
    Nyckelord :liquid film; critical thickness; boiling; critical heat flux; rupture; dry spot; confocal optical sensor; SRA - Energy; SRA - Energi;

    Sammanfattning : Study of liquid film dynamics is of significant importance to the understanding and control of various industrial processes that involve spray cooling (condensation), heating (boiling), coating, cleaning and lubrication. For instance, the critical heat flux (CHF) of boiling heat transfer is one of the key parameters ensuring the efficiency and safety of nuclear power plants under both operational and accident conditions, which occurs as the liquid layers (microlayer and macrolayer) near the heater wall lose their integrity.
