  1. 1. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Louise Westin; [2023]
    Nyckelord :Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

    Sammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER

  3. 2. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Christian Rotter; Erik Fagerberg; [2023]
    Nyckelord :additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

    Sammanfattning : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. LÄS MER

  4. 3. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Minna Olsson; [2023]
    Nyckelord :metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Sammanfattning : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. LÄS MER

  5. 4. Spår i jorden : en studie av ett extraktionslandskap

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Sebastian Hahn; [2023]
    Nyckelord :extraktionslandskap; nymaterialism; landskapshistoria; mosse; torv; torvtäkt; postindustriellt landskap; spårande; rumslighet;

    Sammanfattning : Detta examensarbete utforskar torvtäkten som landsakap. Torvindustrin har en långtgående historia i Sverige, och de utdikade torvmossarna utgör några av de största landskapssåren i landet. Under påtryckningar från politik och samhälle har industrin minskat kraftigt, och många torvtäkter hotas nu av nedläggning. LÄS MER

  7. 5. Matter Manifesting Itself : Understanding Nonhuman Agency in Ovid’s Metamorphoses

    Master-uppsats, Stockholms universitet/Romanska och klassiska institutionen

    Författare :Johanna Koivunen; [2022]
    Nyckelord :ecocriticism; new materialism; agency; materiality; transformation; nonhuman; latin; ancient literature; roman literature;

    Sammanfattning : This thesis examines transformations of human characters into trees, stones, and water sources in Ovid’s Metamorphoses. The current climate crisis is partly the result of a view of nature as a passive object, or inert matter, that humans without consequences can exploit. LÄS MER
