  1. 11. Harvesting and utilizing beach cast on Gotland : A study of the benefits, challenges and opportunities of turning a waste into a resource

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Filip Dessle; [2017]
    Keywords : Beach cast; macroalgae; bioenergy; biofertilizer; eutrophication; cadmium;

    Abstract : Accumulation of beach cast biomass on coastal zones around Gotland is an increasing problem that reduce the recreational value of beaches and cause environmental degradation of coastal environments. Beach cast was once regularly harvested on Gotland, as it was considered a valued biofertilizer, but as it seized to be used in combination with the eutrophication of the Baltic sea, beach cast accumulation has increased in scale.

  3. 12. Heavy metal removal and water treatment using Upsalite

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Philip Erenbo; [2017]
    Keywords : Upsalite; lead; cadmium; nickel; MgO3; heavy metal; water treatment;

    Abstract : Ion exchange reactions between Upsalite, a mesoporous magnesium carbonate, and metal ions of cadmium, lead and nickel have been studied to evaluate the capacities of Upsalite as a water treatment agent. Uptake capacity and reaction kinetics have been evaluated using a batch experiment and atomic absorption spectroscopy. READ MORE

  4. 13. Plasmonic Effect of Metal Nanoparticles Deposited on Wide-Band Gap Metal Oxide Nanowire Substrate

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mojtaba Gilzad Kohan; [2017]
    Keywords : plasmonic particles; nano wires; wide band gap semiconductors;

    Abstract : The application of nanowires (NWs) in solar cells (SCs) is of great interest due to their new promising aspects established in nanoelectronics. Semiconductors associated with plasmonic metal nanoparticles (NPs) such as Silver (Ag), Gold (Au) and Copper (Cu), show enhanced performance in solid state light absorbing SCs owing to plasmonic characteristic of noble metal NPs.

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Emma Lundström; [2017]
    Keywords : tungmetaller; upptag; urban odling; växter; skyddsmekanismer; kontaminering;

    Abstract : För att få en uppfattning av innehållet av tungmetall i urbant odlade grödor analyserades halterna av bly och kadmium i maskrosor (Taraxacum officinale) och jordprov från i Malmö stad. Provpunkterna fördelades brett i staden och kategoriserades efter markanvändning och grad av förorening. READ MORE

  6. 15. Effekten av en kontinuerlig glukosinfusion på triglyceridmetabolismen hos hästar med varierande grad av insulinkänslighet

    University essay from SLU/Dept. of Clinical Sciences

    Author : Helena Johansson; [2016]
    Keywords : kontinuerlig glukosinfusion; triglyceridmetabolism; insulinresistens; hyperlipidemi;

    Abstract : Kritiskt sjuka hästar som utsätts för kraftig fysiologisk stress kan drabbas av negativ energibalans och störningar i glukos- och fettmetabolismen. Fysiologisk stress aktiverar en neuroendokrin respons för att bevara homeostas. READ MORE
