  1. 16. The Good, the Bad & the Ugly - an exploratory study of impact investors’ perceptions of impact, return and risk.

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Linus Andersson; David Andersson; [2017-06-30]
    Nyckelord :impact investor; consumer behavior; impact investing; ethical investments; SRI; perceived risk; trust; PCE; return; impact;

    Sammanfattning : In consumer research, the decision-making process of ethical investors has foremost been studied in the context of ESG- and SR investments. However, little attention has been paid to the new breed of ethical investments; impact investments. LÄS MER

  3. 17. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Hedda Jönsson; Anna Wiberg; [2017]
    Nyckelord :Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.

  4. 18. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Jonatan Fast; [2017]
    Nyckelord :Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Sammanfattning : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  5. 19. Modulhustillverkning i fabrik : Standardisering i tillverkningsindustrin

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Kwadwo Owusu-Mari; Philip Siltberg; Erica Lundkvist Siltberg; [2017]
    Nyckelord :industriell ekonomi; byggindustri; Prefabricering; SIP-metoden; modulhus; standardisering; processcykel effektivitet PCE ; spagettidiagram;

    Sammanfattning : Studien undersöker hur ett byggföretag som arbetar med prefabricering kan standardisera dess produktionsprocess och stödaktiviteter. Studien försöker även genom reducering eller eliminering av slöseri förbättra processcykel effektiviteteten. Studien genomförs på ett fallföretag. LÄS MER

  7. 20. Framtagande av platsspecifik grundvattenmodell samt modellering av klorerade lösningsmedels spridning i grundvatten kring industritomt : – Utvärdering av nuvarande samt framtida föroreningssituation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Julia Inkapööl; [2017]
    Nyckelord :Förorenad mark; Grundvattenmodellering; Föroreningstransport; MODFLOW; RT3D; Sekventiell nedbrytning; Klorerade lösningsmedel;

    Sammanfattning : One of the Government's environmental quality objectives is to achieve a poison free environment, meaning that the presence of anthropogenic substances in the environment should not pose a threat to human health or biodiversity. Such a substance is chlorinated aliphatic hydrocarbons which have been used historically in dry cleaning and as degreasing agents within industrial processes. LÄS MER
