  1. 6. KONTAMINERET KEYBOARD I ULTRALYD - ET KVANTITATIVT STUDIE OM BAKTERIEL FOREKOMST PÅ ULTRALYDSAPPARATER

    Magister-uppsats, Göteborgs universitet/Institutioen för biomedicin

    Författare :Brian Seneca Schmidt; [2023-12-22]
    Nyckelord :Smittskydd och vårdhygien; ULTRALYD; KONTAMINERET;

    Sammanfattning : Baggrund: Med et stort flow af ambulante og indlagte patienter til ultralydsundersøgelse på røntgenafdelingen på Hvidovre Hospital, København, er der dagligt mange berøringsflader med patienter og patientkategorier. Kritisk syge der ikke kan transporteres til røntgenafdelingen fx intensivpatienter, undersøges på stuen med mobile ultralydsapparater. LÄS MER

  3. 7. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  4. 8. Lead Concentrations in Indoor Dust : Differences Between Indoor Shooting Ranges and Assumed Non-Lead Contaminated Sites

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Lena Brolin; [2023]
    Nyckelord :Ammunition; environmentally friendly ammunition; lead; lead at indoor shooting ranges; lead exposure.;

    Sammanfattning : A projectile which missed its target and falls into the bullet trap at the end of the shooting range might not be viewed as dangerous. Yet, hazardous fumes and fine metal fragments from the bullet might contaminate the users of the shooting range. LÄS MER

  5. 9. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ivana Pia Saric Söderholm; Erik Readwin; [2023]
    Nyckelord :Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

    Sammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

  7. 10. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Frida Aronsson; [2023]
    Nyckelord :contaminated soil; arsenic; zero-value iron; mZVI; pilot test; pilot study; förorenad mark; arsenik; nollvärt järn; mZVI; pilotförsök; pilotstudie;

    Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER
