  1. 21. Efficiency of diatom and flagellate-based marine food webs.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Yasmina Hamladji; [2021]
    Keywords : phytoplankton; flagellate; diatoms; ciliates food web efficiency; fungi;

    Abstract : Aquatic microbial food webs are in general size structured. Phytoplankton, which constitute the base of the food web, are grazed by protozoa and mesozooplankton, which in turn are consumed by planktivorous fish. Food web efficiency (FWE) is a measure of how efficiently energy is transported up the food web. READ MORE

  3. 22. Renewable Microgrid : Design and modelling of a potential microgrid by analyzing the renewable resource at island Östergarnsholm to supply the inhabitants of Herrvik with electricity and fresh drinking water

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Noor E Hira Gilani; [2021]
    Keywords : Renewable microgrid; Östergarnsholm; Herrvik; Islanded microgrid;

    Abstract : This project is aimed at developing a model for an off-grid microgrid by studying the wind and solar resource at Östergarnsholm, an island to the east of Gotland, Sweden. For the required consumption, a study and analysis of Herrvik’s local demand has been made which is a village close to the island and the possibility for implementing the microgrid to supply electricity to the inhabitants of Herrvik has been examined.

  4. 23. Offshore Wind Power Foundations' Corrosion Protection Strategy : Anlysis remotely controlled corrosion protection system and comparison to traditional corrosion protection of offshore wind foundation

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Mazen Alhamalawi; [2021]
    Keywords : natural potential; corrosion; corrosion protection system; GACP; ICCP and sacrificial anodes; naturlig potential; korrosion; korrosionsskyddssystem; GACP; ICCP och offeranoder;

    Abstract : När en metall är omgärdad av en elektrolyt, så som havsvatten, kommer det att byggas upp en naturlig potential. Det sker en elektronvandring mellan materialet och havsvattnet och ju större potentialskillnad desto större sannolikhet att metallen kommer korrodera. READ MORE

  5. 24. A Laboratory-Scale Examination to Find an Optimal Application for a Groundwater Barrier Well

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Tatsuya Nagino; [2021]
    Keywords : Groundwater; Seawater intrusion; Countermeasure; Negative hydraulic barrier; Sea level rise; Coastal aquifer; Technology and Engineering;

    Abstract : Seawater intrusion has been aggravated due to anthropogenic reasons, such as sea level rise and over abstraction of groundwater, which is spoiling the groundwater sustainability. This study focused on a negative hydraulic barrier using a barrier well as a countermeasure. READ MORE
