  1. 11. Environmental fate of chemicals released from consumer products : Multimedia modelling strategies

    Författare :Anna Palm Cousins; Michael McLachlan; Antonio Di Guardo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multimedia fate model; urban model; PBDEs; phthalate esters; indoor environment; emissions; exposure; BDE 209; DINP; DEHP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The objective of this thesis was to assess the environmental fate and transport of chemicals emitted from consumer products through the development and application of modelling tools. The following hypotheses were tested: i) Multimedia fate models can be applied in a multistage assessment process to emerging chemicals when limited knowledge exists to identify the likely environmental fate and to direct further research; ii) the indoor environment acts as a source of anthropogenic substances in consumer products to the outdoor environment; and iii) chemical removal pathways in the indoor environment are important for the fate of organic chemicals in densely populated areas.

  3. 12. Anti-Ageing Strategies : How to avoid failure in sodium-ion batteries

    Författare :Le Anh Ma; Reza Younesi; Daniel Brandell; Laurent Duda; Philipp Adelhelm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries; manganese-based cathodes; solid electrolyte interphase; ageing mechanism; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. LÄS MER

  4. 13. Strävan efter legitimation : en finländsk socialarbetarorganisations professionaliseringsstrategier

    Författare :Weckström Marcus; Ulrika Järkestig Berggren; Jesper Johansson; Ilse Julkunen; Linnéuniversitetet; []

    Sammanfattning : This thesis focuses on professional strategies carried out by the Finnish socialworkers union Talentia to strengthen social welfare professions in Finland. Specialfocus lies on the social worker’s occupation and quest for licensure. The period investigated spans from 1949 until 2019. LÄS MER

  5. 14. Food insecurity and coping strategies in semiarid areas : the case of Mvumi in central Tanzania

    Författare :Emma T. Liwenga; Tor A Benjaminsen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Food insecurity; semiarid; local knowledge; seasonality; coping strategies; livelihood strategies.; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : This study examines how people in dryland areas cope with food insecurity and adversities over time. It draws from the experience of the Gogo people living in Mvumi in the semiarid zone of central Tanzania, an area with a long history of food shortages. The study specifically examines the potential for dryland resources to sustain livelihoods. LÄS MER

  7. 15. Route Adaptation of Charge strategies for Hybrid Vehicles

    Författare :Jan Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; modelling; control strategies; road model route adaptation; powertrain; charge strategies; simulation; hybrid vehicle; vehicle propulsion;

    Sammanfattning : For vehicles with energy storage devices, here referred to as hybrid vehicles, the control of the system is of great importance. The hardware system can not be judged without its control. This thesis describes a method for determining the potential of an arbitrary vehicle propulsion system for a prescribed driving mission.
