  1. 16. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Alma Fahlén Hammar; [2023]
    Keywords : Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  3. 17. Investigations of miR-34a structure and dynamics by SHAPE MaP and optimal time between transfection and modification by qPCR

    University essay from KTH/Proteinvetenskap

    Author : Ellinor Lindén; [2023]
    Keywords : SHAPE MaP; qPCR; miRNA; HNF4α; mRNA-34a; SHAPE MaP; qPCR; miRNA; HNF4α; mRNA-34a;

    Abstract : microRNA (miRNA) är korta icke-kodande RNA sekvenser som har fått ökande uppmärksamhet då de kan binda till mRNA och styra vårt genuttryck. Omkring trettio procent av våra proteinkodande gener styrs av miRNA. miRNA binder till mRNA vilket hindrar dess translation eller leder till nedbrytning av mRNA. READ MORE

  4. 18. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

  5. 19. Investigating Yttrium Ruthenate Pyrochlore as an Anodic Electrocatalyst in Proton Exchange Membrane Water Electrolysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kneev Sharma; [2023]
    Keywords : ;

    Abstract : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. READ MORE

  6. 20. Predictive control of fuel cell hybrid construction machines

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
