  1. 1. Tribology of newly developed EAL versus water in hydropower turbine bearings

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

    Author : Nayan Dhakal; [2019]
    Keywords : water-based lubrication; hydropower; turbine bearings; environmentally adaptive lubricants; modified water; viscosity modifiers; polyvinylpyrrolidone; poly sodium 4-styrenesulfonate ; UHMWPE; wear;

    Abstract : The increasing demand for more readily bio-degradable, renewable and non-toxic environmentally adaptive lubricants with a lower degree of bioaccumulation has escalated the investigation of water-based lubricants as the potential alternatives for conventional mineral-based oils. Water is an excellent environmentally adapted lubricant; however, it is a low viscous fluid and holds downsides of having corrosive nature and extremely low pressure-viscosity coefficient leading to insufficient load-carrying capacity.

  2. 2. Use of MMC for Treatment of Pharmaceutical Residues in Wastewater

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Laura Calmanovici Pacoste; [2019]
    Keywords : wastewater treatment; pharmaceutical; pollutions; environment; mesoporous magnesium carbonate; adsorption;

    Abstract : Environmentally hazardous pharmaceutical residues in wastewater cannot successfully be removed by standard treatment procedures used in Swedish wastewater plants. There is a need for cheap, efficient techniques for removing pharmaceutical residues from wastewater. READ MORE

  3. 3. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Eimantas Gladkauskas; [2019]
    Keywords : Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Abstract : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  4. 4. Optimization of modified moisture measurement with Karl Fischer to measure moisture content in freeze-dried enzyme beads for improvement of diagnostic kits

    University essay from KTH/Kemiteknik

    Author : Catharina Jakobsson; [2019]
    Keywords : Mettler Toledo C30S Compact Karl Fischer-coulometer;

    Abstract : Cepheid provides instruments and tests for molecular diagnostic testing of bacterial and viral diseases. Their goal is to deliver a better way to improve patient outcomes by enabling access to molecular diagnostic testing everywhere. These test kits are used in warm and humid countries which may challenge the stability of the kits. READ MORE

  5. 5. Hydropower forecast in Ethiopia using the HBV model - A case study in Omo-Gibe river basin

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Youssef Faouzi; [2019]
    Keywords : Hydropower; Omo-Gibe; HBV model; rainfall-runoff; Ethiopia; Technology and Engineering;

    Abstract : Ethiopia produces 86% of its electricity from hydropower source, still they experience frequent power shortages. As they are part of the East African Power Pool, this power shortage is usually made up for by buying energy from other members of the pool. READ MORE
