1. 16. I hettan från ångpannan : Vetenskap och politik i konflikter om tekniska anläggningar

   Författare :Robert Hrelja; Jonas Anshelm; Göran Sundqvist; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste incineration; Energy; Citing controversy; Environmental disputes; Strategies; Actor-network theory; Skövde; Avfallsförbränning; Energi; Lokaliseringskonflikter; Miljökonflikter; Strategier; Aktörsnätverksteori; Skövde; Technology and social change; Teknik och social förändring;

   Sammanfattning : Denna avhandling analyserar miljökonflikter i anslutning till storskaliga tekniska anläggningar. Miljökonflikter uppkommer när det finns konkurrerande mål bland aktörer och formas av förhandlingsprocesser mellan olika aktörer där vetenskap, teknik och politik vävs samman. LÄS MER

3. 17. Mercury and dioxins in a MercOx-scrubber

   Författare :Carl-Johan Löthgren; Bert Allard; Bert van Bavel; Sven Andersson; Ivars Neretnieks; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waste incineration; flue gas cleaning; PCDD PCDF; PBDD PBDF; wet scrubber; Chemistry; Kemi; Kemi; Chemistry;

   Sammanfattning : The removal of mercury and the absorption of dioxins in an acid wet scrubber have been studied in industrial scale. Hydrogen peroxide is added as an oxidizing agent to the scrubber liquid with the purpose to remove SO2 and enhance the removal of mercury. LÄS MER

4. 18. RF Wireless Power Transfer for IoT Applications

   Författare :Morteza Tavana; Emil Björnson; Jens Zander; Ayça Özçelikkale; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; Energy harvesting; Internet of things; transceivers; wireless power transfer; wireless sensor networks; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : With the emergence of the Internet of things (IoT) networks, the replacement of batteries for IoT devices became challenging. In particular, the battery replacement is more expensive and cumbersome for scenarios where there are many IoT devices; or where the IoT devices are in unreachable locations; or when they have to be replaced often.

5. 19. RF Energy Harvesting for Zero-Energy Devices and Reconfigurable Intelligent Surfaces

   Författare :Morteza Tavana; Emil Björnson; Jens Zander; George Alexandropoulos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; energy harvesting; Internet of Things; optimization; phased array; reconfigurable intelligent surfaces; stochastic geometry; wireless power transfer; wireless sensor networks; zero-energy devices.; Elektronikskrot; energiutvinning; sakernas internet; optimering; fasstyrda antenner; omkonfigurerbara intelligenta ytor; stokastisk geometri; trådlös kraftöverföring; trådlösa sensornätverk; nollenergienheter.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The growth of Internet of Things (IoT) networks has made battery replacement in IoT devices increasingly challenging. This issue is particularly pronounced in scenarios with a large number of IoT devices, in locations where IoT devices are difficult to access, or when frequent replacement is necessary. LÄS MER

7. 20. Solid waste and the water enviroment in the new European Union perspective

   Författare :Marcia Marques; KTH; []
   Nyckelord :;

   Sammanfattning : Processes that occur during storageand final disposal ofsolid waste were studied, with emphasis on physical andchemical aspects and their effects on the water environment,within the New European Union perspective for landfilling(Council Directive 1999/31/EC, 1999).In the new scenario, landfilling is largely restricted;waste treatments such as incineration, composting, recycling,storage and transportation of materials are intensified.
