    Nyckelord :Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Sammanfattning : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. LÄS MER

  4. 3. Nitrifikation i biofilmen i en IFAS

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Magnus Lindén; [2020]
    Nyckelord :IFAS; Biofilm; Nitrification; Ciliate; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : Ökande belastningar, hårdare krav på avloppsreningsverk och ytbegränsningar skapar ett behov av kompakta, effektiva processlösningar. En sådan lösning är en Integrated Fixed film Activated Sludge (IFAS) som kombinerar en aktivslam (AS) med en biofilmsprocess. LÄS MER

  5. 4. A Water Resistant Film Forming Emulsion - The First Steps towards a Topical Preventive Product against Intertriginous Dermatitis

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ida Moen Larsson; [2017]
    Nyckelord :pharmaceutical technology; läkemedelsteknologi; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Sammanfattning : Intertriginous dermatitis (Intertrigo) is a skin disease caused by friction between adjacent skin surfaces. Heat and moisture induces an inflammation, causing pain and often secondary infections. The aim of this degree project was to develop a prototype for a topical film forming emulsion for patients suffering from Intertrigo. LÄS MER
