  1. 1. Utvärdering av sojalecithin som ett alternativ till äggula vid frysning av hundsperma

    University essay from SLU/Dept. of Clinical Sciences

    Author : Elaine Sandell; [2015]
    Keywords : spermafrysning; hundsperma; sojalecithin; äggula; cryopreservation; canine semen; soybean lecithin; egg yolk;

    Abstract : Fryst eller kyld sperma används ofta vid artificiell insemination på hund. Skador kan uppstå på spermierna under frysningsprocessen. För att spermierna ska bibehålla sin viabilitet och undvika skador tillsätts spädningsvätskor som bland annat innehåller sockerarter, antibiotika, glycerol och äggula. READ MORE

  2. 2. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

    University essay from Högskolan i Borås/Ingenjörshögskolan (IH)

    Author : Nima Esmaeili; Shahrzad Javanshir; [2014-01-28]
    Keywords : Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

    Abstract : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.

    Keywords : ;

    Abstract : Lignocellulosic hydrolysates such as spruce and Arundo donax were used in Separate Hydrolysis and Fermentation (SHF) process to analyse the fermentative performance of each recombinant Saccharomyces cerevisiae strain: GS1.11-26 and VTT C-10883, engineered for xylose utilization. In shake flask experiments, GS1. READ MORE

  5. 5. Tribological Performance of Different Coating-lubricant Systems

    University essay from Luleå/Department of Engineering Sciences and Mathematics

    Author : Xin He; [2012]
    Keywords : ;

    Abstract : Diamond-like carbon (DLC) coatings on steel are used to protect mechanical components, to improve lubrication properties such as anti-wear and friction reduction under certain operating conditions. The objectives of this work are (1) to evaluate the compatibility of lubricant with DLC in the boundary lubrication regime by laboratory tribo-test (2) to investigate lubrication mechanism using instrumental analysis.
