  1. 1. LEO Satellite Connectivity for flying vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jinxuan Chen; [2023]
    Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  3. 2. Platsens betydelse för växtnäringsläckage från jordbruksmark i Sverige

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Frida Lundell; [2023]
    Nyckelord :kväve- och fosforutlakning; rumslig variation; långtidsövervakning;

    Sammanfattning : Växtnäringsläckage av kväve (N) och fosfor (P) från jordbruksmark tillför näringsämnen till hav och vattendrag. Det är viktigt att minska transporten av N och P av flera anledningar, då det bland annat är en stor bidragande faktor till övergödning. LÄS MER

  4. 3. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  5. 4. Greenhouse gas emissions and carbon burial in a small pond

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maria Carlson; [2023]
    Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER

  7. 5. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yanhe Zhou; [2023]
    Nyckelord :Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

    Sammanfattning : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. LÄS MER
