  1. 16. Chitosan biopolymer as an adsorbent for drinking water treatment Investigation on Arsenic and Uranium

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Md Annaduzzaman; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chitosan Biopolymer; Characterization; Biodegradable; Arsenic V ; Uranium VI ; Adsorption; Isotherm; Kinetic model  ; Chitosan; Biopolymer; Karakterisering; Bionedbrytbar; arsenik V ; uran VI ; Adsorption; Isoterm; Kinetisk modell; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. LÄS MER

  2. 17. User-Centred Design and Technology-Mediated Services- Identifying and Addressing Challenges by Analysing Activities

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Oskar Rexfelt; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology-mediated services; product development; user requirements; User-centred design; service development; user studies;

    Sammanfattning : User-centred design has a focus on designing products to satisfy user needs rather than emanating from a technological starting point. Understanding user needs when developing products is considered a key component to achieve market success today.User-centred design is almost always described as a way to design products that satisfy user needs.

  3. 18. Contribution of stormwater ponds for road runoff to aquatic biodiversity

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Zhenhua Sun; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; road salt; stormwater ponds; water quality; sediments; road runoff; metals; pond size; aquatic biodiversity;

    Sammanfattning : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. LÄS MER

  4. 19. Influence of deformation and environmental degradation of Inconel 792

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jan-erik Kanesund; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Industrial gas turbines are often used as a mechanical drive for pumps and compressors or in power generation as an electric power supply. The gas turbine has for many years been a popular engine due to its flexibility with respect to different types of fuel and due to a design, that enables a high power-to-weight ratio. LÄS MER
