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

    University essay from KTH/Skolan för kemivetenskap (CHE)

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

    Abstract : 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.

  3. 17. Degradation and restoration method interact to affect the performance of planted seedlings in tropical rainforest restoration : evidence from plant functional traits

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Julia Mellåker; [2016]
    Keywords : Dipterocarpaceae; enrichment planting; INIKEA; secondary rainforest; hjälpplantering; sekundär regnskog;

    Abstract : A common action to improve or save biodiversity in the tropics is restoration of degraded rainforest. To understand the complex ecological structures of the forest and adapt the restoration actions after them, studies have focused on characterizing species with functional traits. READ MORE

  4. 18. Skalbaggars artsammansättning efter intensiv skogsbrand : en jämförelse mellan artgrupper två år efter brand

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Teresa Leifsdotter; Anna Nilsson; [2015]
    Keywords : specialister; generalister; brandgynnad; rödlistad; funktionella grupper; boreal skog; störning;

    Abstract : Skogsbränder har idag blivit något ovanligt och arter som är beroende av bränder för reproduktion och födotillgång blir därför missgynnade. Idag finns en hypotes om att vissa arter som gynnas av kalhyggesbruk konkurrerar ut brandspecialiserade arter och är en anledning till dessa arters tillbakagång. READ MORE

  5. 19. Specificity and characteristics of fuzzy complexes -- Modelling of intrinsically disordered proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Karolina Mothander; [2015]
    Keywords : specificity; Monte Carlo; Fuzzy complexes; Intrinsically disordered proteins; Physics and Astronomy;

    Abstract : Intrinsically disordered proteins are fully functional proteins without a three-dimensional structure. Intrinsically disordered proteins can, in the same way as ordered proteins, interact with other proteins to fulful their function. READ MORE

  6. 20. Evaluation of the Removal Efficiency of Per- and Polyfluoroalkyl Substances in Drinking Water using Nanofiltration Membranes, Active Carbon and Anion Exchange

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Klara Lindegren; [2015]
    Keywords : PFASs; perfluoroalkyl substances; removal efficiency; NF; nanofiltration; membrane; GAC; granular activated carbon; AE; anion exchange; PFAS; perfluorerade alkylsubstanser; reningseffektivitet; NF; nanofiltrering; membran; GAC; granulärt aktivt kol; AE; jonbytarmassa;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) is a group of man-made, highly persistent chemicals. Due to the specific surface-active attributes of these molecules, applications are numerous and feed an economically important industry. During the last decade, PFASs have been detected globally in the environment, living organisms and tap water. READ MORE
