  1. 1. Effekt av blåbär på blodlipider En systematisk litteraturöversikt om effekt av blåbärsintag på blodlipider.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för medicin

    Författare :Vendela Welander; Viktoria Morell; [2024-02-09]
    Nyckelord :Lipids; LDL; HDL; total cholesterol; triglycerides; blueberries; anthocyanins; Lipider; totalkolesterol; triglycerider; blåbär; antocyanin;

    Sammanfattning : Syfte: Syftet är att sammanställa det aktuella forskningsunderlaget för att undersöka om intag av blåbär förändrar lipidnivåer hos män och kvinnor ≥18 år jämfört med att inte inta blåbär. Metod: I denna systematiska översiktsartikel har en litteratursökning genomförts. LÄS MER

  3. 2. Synthesis and characterization of a greener poly(vinyl acetate) adhesive

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Xiuting Zhang; [2023]
    Nyckelord :poly vinyl acetate -grafted-chitosan; chitosan; poly vinyl acetate ; ceric ammonium nitrate; green adhesive; poly vinyl acetat -ympad kitosan; poly vinyl acetat ; ceriumammoniumnitrat CAN ; grönt lim;

    Sammanfattning : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. LÄS MER

  4. 3. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
    Nyckelord :Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

    Sammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER

  5. 4. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Sara Falk; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. LÄS MER

  7. 5. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Elina Elvelo; [2023]
    Nyckelord :alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Sammanfattning : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.
