    Abstract : Strukturrationaliseringen i jordbruket påverkar i stor utsträckning lantbruksmaskinernas storlek vilket gör att vi går mot allt större och tyngre maskiner. Detta påverkar i stor utsträckning markpackningen. Ett sätt att komma förbi detta är att använda sig av fasta körspår (CTF ). READ MORE

  5. 24. Lipase-based in vitro release assays for pharmaceutical lipid formulations

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Leonard Saffer; [2015]
    Keywords : phospholipase; triacyl glycerol lipase; in vitro release; fluorescein.; patent blue; pharmaceutical technology; läkemedelsteknologi; Lipid formulation; phosphatdyl choline; glycerol dioleate; Biology and Life Sciences;

    Abstract : The purpose of this project was to develop and test lipase-based in vitro release (IVR) assays for model and active pharmaceutical ingredients (API) entrapped in lipid formulations based on mixtures of phosphatidylcholine (PC) and glycerol dioleate (GDO). Two dyes, Fluorescein disodium salt and Patent Blue V sodium salt, functioning as model drug compounds, were investigated separately in the PC/GDO formulation. READ MORE

  6. 25. Bioremediation of textile dyes and improvement of plant growth by marine bacteria

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Pandu Krishna Compala Prabhakar; [2013]
    Keywords : Bioremediation; textile dyes; marine bacteria;

    Abstract : Textile industries are the major users of dyes in the world. A huge fraction of dyes are discharged out from the textile industries, causing serious damage to the environment. Bioremediation based technologies has been proved to be the most desirable and cost- effective method to counter textile dye pollution. READ MORE
