  1. 1. Analysis of granulated carbide powder and how it affects pressing

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Nyckelord :Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Sammanfattning : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. LÄS MER

  3. 2. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Nyckelord :;

    Sammanfattning : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. LÄS MER

  4. 3. Phosphorus accumulation in a free water surface wetland discharging into the Baltic Sea

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Manuela Watschka; [2021]
    Nyckelord :free water surface wetland; phosphorus accumulation; internal loading; sediment accumulation;

    Sammanfattning : Eutrophication has been an issue of the Baltic Sea for a long time, causing de-creased water clarity due to enhanced growth of algae and oxygen depletion dur-ing the decomposition of algae. The study investigated the free water surface wetland Vilhelmsberg that treats agricultural runoff before the water reaches the Baltic Sea. LÄS MER

  5. 4. Karakterisering av kommunalt avloppsvatten - Partikelstorleksfördelning och sammansättning av COD

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sara Tebini; [2020]
    Nyckelord :avloppsvatten; karakterisering; COD; respirometri; partikelstorleksfördelning; förbehandling; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental enginering; Technology and Engineering;

    Sammanfattning : Inkommande avloppsvatten till ett reningsverk består till största delen av organiskt material som i sin tur kan utgöra en viktig resurskälla för reningsverket. Genom att utnyttja kolet i avloppsvattnet för produktion av metan kan ett reningsverk bli självförsörjande på energi. LÄS MER

  7. 5. Extrusion of grass silage and its effect on feed intake, milk production and ingestive behaviour of dairy cows

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Markos Managos; [2020]
    Nyckelord :extrusion; grass silage; dairy cows; milk production; milk composition; rumen pH; ingestive behaviour;

    Sammanfattning : Grass and clover ley is the main forage crop in Sweden, however, its restrictive role in feed intake limits the total amount included in the diet of a dairy cow. This study examined the effect of extrusion on grass silage intake, milk production, ingestive behaviour and rumen pH. LÄS MER
