    Sammanfattning : Diabetic ketoacidosis (DKA) is a life-threatening condition that can appear in patients with diabetes. High ketones in the blood lead to acidity of the blood. For DKA diagnosis and management, ketones such as hydroxybutyrate (HB) can be used to quantify the severity of the disease. LÄS MER

  3. 2. Engineering Rhodosporidium toruloides for the production of polyhydroxybutyrate

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Tova Lindh; [2021]
    Nyckelord :Applied microbiology; Bioplastics; Rhodosporidium toruloides; Polyhydroxybutyrate; Non-conventional yeast; Oleaginous yeast; Biology and Life Sciences;

    Sammanfattning : The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin.

  4. 3. Structural modifications of polyester fibres induced by thermal and chemical treatments to obtain high-performance fibres

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Kartikeya Sharma; [2021]
    Nyckelord :PET fibres; P3HB fibres; Radial gradient; Chemical modification; Thermal annealing; High-performance fibres; PET-fibrer; P3HB-fibrer; Radiell lutning; Kemisk modifiering; termisk glödgning; högpresterande fibrer;

    Sammanfattning : Del A: Polyetylentereftalat fibrer I detta arbete presenteras olika metoder för att framställa monofilament av polyetylentereftalat (PET) (diameter: 30-50 µm) med en radiell gradient. Nyutvecklad Raman-spektroskopiteknik har använts för att kartlägga dessa inducerade radiella gradienter i t.ex. kristallinitet. LÄS MER

  5. 4. Composition and property study of adhesives based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Sammanfattning : Lim klassificeras som ett ämne som kan hålla ihop två ytor så att de motstår separation. Dagens lim kan anpassas efter vilken applikation de ska användas till och kan ha ett stort antal olika egenskaper. De fysikaliska och kemiska egenskaperna av limmet är de viktigaste faktorerna för att bilda en bra limbindning. LÄS MER
