  1. 1. Development of a Method to Predict the Adhesion of Industrial Paint Coating

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Akheen Sadik; [2022]
    Nyckelord :Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

    Sammanfattning : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. LÄS MER

  3. 2. Changes in Running Technique At Shod and Barefoot Running Condition : - An analysis of Muay Thai Fighters

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Therese Sjöholm; [2019]
    Nyckelord :running technique; barefoot running; may thai; thai boxing; running analyses; löpteknik; barfotalöpning; muay thai; thaiboxning;

    Sammanfattning : Background: everal studies mean that individuals accustomed to running barefoot and habitually barefoot individuals choose a fore foot or mid foot strike rather than a rear foot strike when running. This is partly to do with the proprioceptive feedback given from the soles of the feet. LÄS MER

  4. 3. Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilisers with Increased Nutrient Use Efficiency

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Xueyan Xu; [2017]
    Nyckelord :fertilizer coating; lignin; modified lignin; polylactide; slow release; ytbeläggning för gödningsmedel; lignin; modifierad lignin; polylaktid; kontrollerad frisättning;

    Sammanfattning : Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic sulphur and synthetic polymers have been used in the industry as coating materials together with utilization of various types of expensive coating equipment which commonly requires also complicated technical setup and controls.

  5. 4. Analysis of Changes in Running Technique Between a Shod and Barefoot Running Condition.

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Matilda Andersson; [2016]
    Nyckelord :biomechanics; running; barefoot; running technique;

    Sammanfattning : Background: Lately, barefoot running has become popular and there is a debate on the pros and cons of barefoot running with regards to running injuries. Many factors are causing injuries and one of the factors discussed is the fact that we run in shoes. LÄS MER

  7. 5. Hydrophobic Coating on Cellulosic Textile Material by Betulin and a Betulin Based Polymer

    Master-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Tianxiao Huang; [2016]
    Nyckelord :Betulin; biorefinery; cellulose; contact angle; copolymer; hydrophobicity; marketing strategy; standard spray test; textile fibers; water repellency.;

    Sammanfattning : Betulin is a naturally abundant compound in the outer bark of birch and can be easily obtained by solvent extraction. Herein, solutions of betulin were used to treat cellulosic textile fibers and improve their water repellency. Cotton fabrics impregnated in a 7. LÄS MER
