  1. 1. Implementation of an automatic tangential flow filtration system for latex immunoassay production

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Filippa Stolpe; Sofia Kullander; [2023]
    Nyckelord :biotechnology; bioprocess; diagnostics; production; TFF; tangential flow filtration; blood clots; automation; antibodies; latex immunoassay; LIA;

    Sammanfattning : To diagnose patients suffering from blood clotting disorders latex immununoassays (LIA) can be used. A time consuming manual tangential flow filtration (TFF) process suggests the implementation of an automatic TFF system to improve the efficiency, profitability, and expandability of the production facility of LIA at Nordic Biomarker.

  3. 2. Tribological behaviour of metal sulfides UHMWPE composites in dry lubrication

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Bruno Pizone Vaz; [2021]
    Nyckelord :Polymer composites; polymer tribology; dry lubrication; UHMWPE; metal sulfides; tribology;

    Sammanfattning : The increasing worldwide demand for more eco-friendly materials with improved tribo- logical properties has expanded the interest in research on polymer as an alternative for conventional metal/metal contacts under dry lubrication. Specifically, UHMWPE, a semi-crystalline polymer, has shown interesting tribological properties for low demanding applications, allied with excellent recyclability, manufacturability and low cost.

  4. 3. Migration av gummigranulat från konstgräsplaner : En förbisedd miljöfarlig verksamhet

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Karin Widström; [2017]
    Nyckelord :konstgräs; granulat; SBR; miljöfarlig verksamhet;

    Sammanfattning : Tack vare att konstgräsplaner kan användas dygnets alla timmar och årets alla dagar och därmed är väldigt yteffektiva, blir de alltmer vanliga. Men frågor har lyfts om miljöaspekter kopplade till dem. LÄS MER

  5. 4. Plastic as marine debris and its potential for economic value : A practical and analytical estimation of the marine debris characteristics and a comparative evaluation of possible treatment procedures

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Astrid Hartman; Ella Lovén; [2014]
    Nyckelord :;

    Sammanfattning : Every year around 270 million tonnes of plastic are produced worldwide. As a result of poor waste management in many countries, a large amount of it ends up in the world’s oceans where it degrades into micro particles. LÄS MER

  7. 5. Metodjämförelse mellan instrumenten Vitros 5,1 FS och QuikRead CRP för analysen P-CRP

    Kandidat-uppsats, Institutionen för kemi och biomedicin (KOB)

    Författare :Natasha Gacic; [2013]
    Nyckelord :CRP; c-reaktivt protein;

    Sammanfattning : In studies of serum, in the early 1930s, from patients with pneumonia, a factor was found. It could agglutinate certain pneumococcal species. This factor, which later became known as C-reactive protein (CRP), increased sharply during the early and middle stages of the disease. LÄS MER
